Part I

ITEMS 1 AND 2. BUSINESS AND PROPERTIES

In this Form 10-K, “Occidental”, “we”, “our” and “the Company” refers to Occidental Petroleum Corporation, a Delaware corporation incorporated in 1986, or Occidental and one or more entities in which it owns a controlling interest (subsidiaries). Occidental conducts its operations through its various subsidiaries and affiliates. Occidental’s executive offices are located at 5 Greenway Plaza, Suite 110, Houston, Texas 77046; telephone (713) 215-7000.


GENERAL

Occidental’s principal businesses consist of three reporting segments: oil and gas, chemical and midstream and marketing. The oil and gas segment explores for, develops and produces oil (which includes condensate), NGL and natural gas. The chemical segment primarily manufactures and markets basic chemicals and vinyls. The midstream and marketing segment purchases, markets, gathers, processes, transports and stores oil, NGL, natural gas, CO2 and power. It also optimizes its transportation and storage capacity, and invests in entities that conduct similar activities, such as WES.

The midstream and marketing segment also includes OLCV. OLCV seeks to leverage Occidental’s legacy of carbon management expertise to develop CCUS projects, including the commercialization of DAC technology, and invests in other low-carbon technologies intended to reduce GHG emissions from its operations and strategically partner with other industries to help reduce their emissions.


HUMAN CAPITAL RESOURCES

Occidental’s culture is built upon the following core values:

■Lead with Passion

■Outperform Expectations

■Deliver Results Responsibly

■Unleash Opportunities

■Commit to Good

Occidental’s human capital resources and programs are managed by its Human Resources department, with support from business leaders across the Company. Occidental’s senior management team plays a key role in setting and monitoring Occidental’s culture, values and broader human capital management practices, with oversight by Occidental’s Board of Directors, the Sustainability and Shareholder Engagement Committee of the Board and the Environmental, Health & Safety Committee of the Board. The Sustainability and Shareholder Engagement Committee periodically receives briefings on Occidental’s human capital strategy and the Environmental, Health & Safety Committee receives briefings on employee and contractor health and safety statistics and related matters, including workforce health and safety initiatives. Senior management and the Board also engage regularly on workforce-related topics.

To enhance senior leadership’s engagement with employees, Occidental hosts quarterly executive virtual conversations where Occidental’s President and CEO, Vicki Hollub, and other executive officers review recent financial and operational performance as well as topics pertinent to employees. Occidental’s President and CEO also answers employee questions during these conversations. The quarterly executive virtual conversations form one piece of Occidental’s employee outreach and engagement, which consists of newsletters, focus groups and employee resource groups, among other channels and tools.

DIVERSITY, INCLUSION AND BELONGING

Occidental strives to create an environment where employees’ differences are appreciated, celebrated and encouraged. The Company’s human capital resources extend across several regions. Occidental has attracted, and continues to recruit, a diverse workforce of exceptional talent, including employees from many nations. This diversity enriches Occidental’s culture and its employees' experiences on the job and contributes to an innovative and effective business model that encourages local communities to thrive.

The DIB Advisory Board, which is chaired by Occidental’s President and CEO, and includes members of senior leadership, provides DIB governance and oversight to ensure that Occidental’s integrated DIB strategy is executed and aligns with Occidental’s mission, vision and strategic objectives. The DIB Ambassador Committee, which is chaired by Occidental’s Vice President of Diversity and Inclusion, consists of a diverse group of employee representatives from all business segments, domestic and international. This committee leads company-wide initiatives to raise DIB awareness through educational resources and programs. Educational sessions are available to the entire workforce for continued


OXY 2023 FORM 10-K			3


						BUSINESS AND PROPERTIES

growth and development on topics such as inclusive leadership, diversity advocacy, recognizing and addressing micro aggressions, overcoming unconscious bias and psychological safety at work.

Occidental’s senior management, together with the support of Occidental’s DIB Advisory Board and the DIB Ambassador Committee, works to leverage employees’ varied backgrounds, unique experiences and points of view to spark innovation, empower growth, outperform expectations and maximize results.

As part of Occidental’s integrated DIB strategy, the Human Resources department supports eleven Employee Resource Groups. An ERG is a group of employees who actively engage in communicating or gathering around a central purpose, mission, background or activity. ERGs can help advance inclusion and a sense of belonging of employees with a common set of interests and/or goals. The mission and goals of ERGs are fully aligned with Occidental’s expectation to be an employer, partner, and neighbor of choice. Each ERG is inclusive of all employees—everyone can benefit from and participate in an ERG, either as a member or an ally. Occidental’s ERGs are as follows:

•Allyship

•Asian Heritage Network

•Black Employee Network

•Early Career Network

•FRIEND (Friends, Relatives and Individuals Empowering Neurodiversity)

•Hispanic Network

•Mental Health Matters

•Mosaic (Multicultural) Network

•Out (LGBT+) Network

•Veterans Network

•Women of Oxy Network

TALENT ATTRACTION AND RETENTION

Occidental recruits candidates through job fairs, professional societies and campus recruiting, including expanded recruiting at historically black colleges and universities.

To attract and retain talent, Occidental has the Balanced Workplace Program under which eligible office-based employees may opt to work three days in the office and two days at home each week. The program affords employees more flexibility and promotes increased work-life balance.

In addition, Occidental has its global Strategic Technical Excellence Program to recruit, develop and retain highly skilled and valued geoscientists, engineers, scientists and other petrotechnical professionals who collectively drive innovation, advance performance and inspire the future of energy. STEP is a highly valued program for technical contributors to focus and advance on a technical, non-managerial career path and provides a competitive advantage for Occidental through the optimum application of technology. The Chief Petrotechnical Officer leads all aspects of STEP and reports directly to Occidental’s President and CEO.

Occidental also offers employees development opportunities, competitive compensation and attractive benefits, as discussed further below.

DEVELOPMENT AND TRAINING

Occidental employees have access to extensive development and training opportunities and programs to expand their personal and professional skills and knowledge. Occidental’s approach to education includes:

■Leadership/management training to develop leadership skills at all levels;

■Self-directed learning and development, including web-based and instructor-led training;

■An employee development library;

■Mentoring programs;

■Employee resource groups; and

■Educational assistance to support employees’ continuing education.

Occidental has expanded on-demand professional and development classes and mentoring to enhance critical business skills, broaden employee networks, and engage its employees.

EMPLOYEE COMPENSATION AND BENEFITS

Occidental’s compensation and benefits program is designed to attract and retain the talent necessary to achieve its business strategy. The compensation and benefits program recognizes and rewards strong company and individual performance with competitive base salaries, an annual bonus program, recognition awards, long-term performance incentives and advancement opportunities. Occidental’s compensation and benefits program is routinely reviewed and benchmarked to ensure competitiveness and to provide the benefits that matter most to current and future employees.

Occidental strives to give employees the tools and resources they need to succeed both professionally and personally and to foster a safe and collaborative work environment. To that end, Occidental offers, and regularly evaluates, its comprehensive health, welfare and retirement and savings benefits plans, professional memberships and work/life balance

						BUSINESS AND PROPERTIES

benefits. It also provides programs to enhance and support employees’ overall well-being, including their physical, mental, social and financial health.

MENTAL HEALTH

Addressing well-being is imperative to ensure that Occidental’s employees stay resilient, healthy and productive. Over the past several years, Occidental has taken numerous steps to enhance the support of employee mental health. Occidental launched the global well-being campaign “Commit to You” to educate employees and leaders about how its benefits can support them under the four pillars of well-being: mental, physical, social and financial. Occidental also prioritized the importance of mental health and well-being through manager and employee programs and events. One program, sponsored by OxyHealth and the Mental Health Matters ERG, was a "Talk Saves Lives" conversation with the American Foundation for Suicide Prevention to learn about common risk factors, how to spot warning signs in others, and how to keep employees, loved ones, and those in the community safe. Occidental continues to be a member of One Mind at Work, an employer coalition dedicated to implementing a gold standard for workplace mental health by combating stigma, improving access to treatment and prevention services and fostering a psychologically safe culture.

In 2023, Occidental launched an enhanced mental health benefit through Lyra Health. Lyra Health provides cost-free mental and emotional healthcare that is effective, convenient and personalized to all employees and their dependents. Lyra Health professionals provide virtual or in-person support for a variety of mental health concerns including anxiety, depression, stress management, parenting challenges, relationship conflicts and sleep problems. Online tools, mental health courses and other resources are also available with guided meditations, videos and small group discussions to help improve well-being and provide personal and professional development.

HEALTH AND SAFETY

The health and safety of Occidental’s workforce and communities is a top priority as reflected in the Company's HSE and Sustainability Principles. Occidental’s Operating Management System sets expectations, provides guidance, training and resources, and empowers employees and contractors to stop any job or activity if they observe conditions that may give rise to a safety or environmental incident. In 2023, the Company focused on reducing incident severity, enhancing contractor safety programs and harmonizing safety systems, programs and tools. These efforts helped Occidental sustain its robust safety record and promote continued improvements and innovations in safety, efficiency, reliability and environmental stewardship.

						BUSINESS AND PROPERTIES


OIL AND GAS OPERATIONS

GENERAL

Occidental primarily conducts its ongoing exploration and production activities in the United States, the Middle East and North Africa. Within the United States, Occidental has operations primarily in Texas, New Mexico and Colorado, as well as offshore in the Gulf of Mexico. Internationally, Occidental primarily conducts operations in the UAE, Oman and Algeria. Refer to the Oil and Gas Acreage section in Supplemental Oil and Gas Information under Item 8 of this Form 10-K for further disclosure of Occidental’s holdings of developed and undeveloped oil and gas acreage.

COMPETITION

As a producer of oil, NGL and natural gas, Occidental competes with numerous other domestic and international public, private and government producers. Oil, NGL and natural gas are sensitive to prevailing global and local market conditions, as well as anticipated market conditions. Occidental’s competitive strategy relies on producing hydrocarbons in a capital efficient manner through developing conventional and unconventional fields and utilizing primary, secondary (waterflood) and tertiary (CO2 and steam flood) recovery techniques in areas where Occidental has a competitive advantage as a result of its successful operations or investments in shared infrastructure. Occidental also competes to develop and produce its worldwide oil and gas reserves safely, sustainably and cost-effectively, maintain a skilled workforce and use high quality service providers. Occidental believes that its core competencies in CO2 separation, transportation, use, recycling and storage in EOR provide a competitive advantage over its peers as the world transitions to a less carbon-intensive economy and seeks to remove CO2 from the atmosphere.

PROVED RESERVES AND SALES VOLUMES

The table below shows Occidental��s year-end oil, NGL and natural gas proved reserves. See the information under Oil and Gas Segment in the Management's Discussion and Analysis section under Part II, Item 7, of this Form 10-K for details regarding Occidental’s proved reserves, the reserves estimation process, sales and production volumes, production costs and other reserves-related data.

						BUSINESS AND PROPERTIES


MIDSTREAM AND MARKETING OPERATIONS

GENERAL

Occidental’s midstream and marketing operations primarily support and enhance its oil and gas and chemical businesses. The midstream and marketing segment strives to optimize the use of its gathering, processing, transportation, storage and terminal commitments and to provide access to domestic and international markets. To generate returns, the segment evaluates opportunities across the value chain to provide services to Occidental subsidiaries, as well as third parties. The midstream and marketing segment operates or contracts for services on gathering systems, gas plants, co-generation facilities and storage facilities and invests in entities that conduct similar activities, such as WES and DEL, which are accounted for as equity method investments. WES owns gathering systems, plants and pipelines and earns revenue from fee-based and service-based contracts with Occidental and third parties. DEL owns and operates a pipeline that connects its gas processing and compression plant in Qatar and its receiving facilities in the UAE, and uses its network of DEL-owned and other existing leased pipelines to supply natural gas across the UAE and to Oman. The midstream segment includes Al Hosn Gas, a processing facility in the UAE that removes sulfur from natural gas and processes the natural gas and sulfur for sale. The midstream and marketing segment also includes OLCV businesses.

LOW-CARBON BUSINESSES

Leveraging Occidental’s carbon management expertise, OLCV primarily focuses on advancing carbon removal and CCUS projects, including developing and commercializing DAC technology. OLCV also invests in third-party entities that are developing technologies to advance other low-carbon initiatives, including NET Power, a clean energy technology company. In 2023, Occidental acquired Carbon Engineering, a developer of DAC technology, and entered into a joint venture with BlackRock on the construction of STRATOS, Occidental’s first large-scale DAC facility in Ector County, Texas.

COMPETITION

Occidental’s midstream and marketing businesses operate in competitive and highly regulated markets. Occidental competes for capacity and infrastructure for the gathering, processing, transportation, storage and delivery of its products, which are sold at current market prices or on a forward basis to refiners, end users and other market participants. Occidental’s marketing business competes with other market participants on exchange platforms and through other bilateral transactions with direct counterparties. OLCV and its businesses and investees also face a broad range of competitors, with nascent markets for low-carbon products and CO2 removal credits that are subject to rapidly changing laws, regulations, policies and reporting and verification mechanisms that can significantly impact the financing, construction and operation of projects and the development of markets.

Occidental’s midstream and marketing operations are conducted in the locations described below as of December 31, 2023:


Location	Description	Capacity (a)
Gas Plants
Texas, New Mexico and Colorado	Occidental and third-party-operated natural gas/CO2 gathering, compression and processing systems	2.2 Bcf/d
Texas, Rocky Mountains and Other	Equity investment in WES - gas processing facilities	5.2 Bcf/d
UAE	Natural gas processing facilities for Al Hosn Gas	1.45 Bcf/d
Pipelines and Gathering Systems
Texas, New Mexico and Colorado	CO2 fields and pipeline systems transporting CO2 to oil and gas producing locations	2.8 Bcf/d
Qatar, UAE and Oman	Equity investment in the DEL natural gas pipeline	3.2 Bcf/d

ITEM 1A. RISK FACTORS

Risks related to government regulations and the environment

Government actions and political instability may adversely affect Occidental’s businesses and results of operations.

Occidental’s businesses are subject to, and may be adversely affected by, the actions and decisions of many federal, state, local and international governments and political interests. As a result, Occidental faces risks of:

■New or amended laws and regulations, or new or different applications or interpretations of existing laws and regulations, including those related to drilling, manufacturing or production processes (including flaring and well stimulation techniques such as hydraulic fracturing and acidization), pipelines, labor and employment, taxes, royalty rates, permitted production rates, entitlements, import, export and use of raw materials, equipment or products, use or increased use of land, water and other natural resources, air emissions (including restrictions, taxes or fees on emissions of methane, CO2, or other substances), water recycling and disposal, waste minimization and disposal, public and occupational health and safety, the manufacturing of chemicals, asset integrity management, the marketing or export of commodities, security, environmental protection, and climate change-related and sustainability initiatives, all of which may restrict or prohibit activities of Occidental or its contractors or customers, increase Occidental’s costs or reduce demand for Occidental’s products;

■Violation of certain laws and regulations, which may result in strict, joint and several liability and the imposition of significant administrative, civil or criminal fines and penalties and may also result in liability for remedial actions or assessments. Litigation, orders or other proceedings asserting strict, joint and several liability under such laws and regulations may seek to impose significant administrative, civil or criminal fines and penalties, damages or remedial actions or to require significant changes to, or even closure of, facilities or operations;

■Refusal of, or delay in, the extension or grant of exploration, development or production contracts or leases; and

■Development delays and cost overruns due to approval delays for, or denial of, drilling, construction, environmental and other regulatory approvals, permits and authorizations.

Examples of provisions of recent U.S. federal statutes and regulations that affect key aspects of taxation, land use and production or manufacturing operations and present the foregoing types of risks are described in this risk factor, and examples of those regarding climate change and GHG and other air emissions are described in the next risk factor below.

In August 2022, Congress passed and President Biden signed the IRA, which imposed new or reinstated corporate taxes and fees, including those described below, that could have an adverse effect on Occidental’s tax liability. The IRA enacted a new corporate alternative minimum tax (CAMT) that, starting in tax year 2023, imposes a 15% minimum tax on the adjusted financial statement income (AFSI), net the CAMT foreign tax credit, of corporations with average AFSI exceeding $1 billion for three preceding consecutive tax years. In 2023, the IRS issued five notices providing interim guidance on the CAMT and has indicated it will promulgate CAMT regulations in 2024. The IRA also imposed a 1% excise tax on the aggregate fair market value of corporate share repurchases, net of certain corporate share issuances and other adjustments, by certain corporations during the taxable year. In 2023, the IRS issued two notices containing interim guidance clarifying that corporations are not required to report or pay the excise tax until such time and in such manner dictated by IRS regulations that are expected to be issued in 2024. The IRA also provided significant policy support and incentives, including enhanced tax credits, for DAC, CCUS, hydrogen and other low-carbon projects. Finally, the IRA expanded GHG emissions reporting requirements and imposed a new methane emissions charge on owners or operators of various U.S. oil and gas facilities, as described in the next risk factor on climate change and GHG emissions. For additional discussion of such matters, see Note 10 - Income Taxes in the Notes to Consolidated Financial Statements in Part II Item 8 of this Form 10-K.

In November 2021, Congress passed and President Biden signed the Infrastructure Investment and Jobs Act (IIJA). The IIJA reinstated, effective in July 2022, the federal Superfund chemical excise taxes on various listed taxable chemicals that OxyChem manufactures, produces or imports, such as chlorine, sodium hydroxide and ethylene, subject to certain exceptions such as methane used for fuel and exported chemical products. These excise taxes could lead to higher costs and impact margins. The IIJA also authorized federal support, including grants, loans and loan guarantees, for low-carbon ventures and infrastructure, including grants for DAC and CCUS research, development and demonstration, carbon transport and storage infrastructure and permitting, carbon utilization and market development, and carbon removal. In August 2023, 1PointFive, LLC, a wholly owned subsidiary of Occidental (1PointFive), was selected to receive a grant from the U.S. Department of Energy’s Office of Clean Energy Demonstrations for the development of its South Texas DAC Hub. The amount of the grant has not been established and it is subject to completion of agreements with the DOE. The awarding of grants or other federal support under various statutes could affect the selection and deployment of competing low-carbon technologies and the financing and market acceptance of proposed projects of Occidental and its competitors.

In January 2021, President Biden issued an executive order that, among other things, called for the elimination of fossil fuel subsidies from federal budget requests beginning in 2022 and announced a moratorium on new oil and gas leases on federal lands and offshore waters pending a review of existing leases and permitting practices. The moratorium was subject to legal challenge, and in August 2022, the U.S. District Court for the Western District of Louisiana permanently enjoined the moratorium as to 13 states that filed a lawsuit against the action.

Federal resource agencies have sought to significantly restrict or delay leasing and access to federal lands for oil and gas exploration, production and infrastructure, to increase royalty rates, fees and bonding requirements, to impose


10			OXY 2023 FORM 10-K


						RISK FACTORS

significant preconditions, restrictions or delays on permitting, and in certain locations, to prohibit or significantly restrict oil and gas activities under various federal laws, including the IRA, Outer Continental Shelf Land Act, Federal Land Policy and Management Act, Mineral Leasing Act, Mineral Leasing Act for Acquired Lands, Federal Onshore Oil and Gas Leasing Reform Act, NEPA, Marine Mammal Protection Act, Migratory Bird Treaty Act and Endangered Species Act (ESA). For example, offshore leasing is important for Occidental to sustain GOM production and reserves over the long term. The BOEM sought to cancel recent offshore lease sales in 2022 in response to litigation brought by advocacy groups and because its 2017-2022 Outer Continental Shelf Oil and Gas Leasing Program was expiring. After the IRA mandated the reinstatement of those lease sales, as well as increased royalty rates, rental rates and minimum bids and additional fees for offshore and onshore leasing, the BOEM sought in August 2023 to exclude six million acres from Lease Sale 261 and to impose other conditions restricting vessel activity that BOEM contended would protect habitat of the Rice’s whale, which was listed by the National Marine Fisheries Service (NMFS) as an endangered subspecies of the Bryde’s whale in 2019. After the U.S. District Court for the Western District of Louisiana ordered the BOEM to conduct the sale without the exclusion of acreage and restrictions the BOEM had proposed with respect to the Rice’s whale, and the U.S. Court of Appeals for the Fifth Circuit upheld that order, the BOEM conducted Lease Sale 261 in December 2023. In December 2023, the BOEM also published its Record of Decision and Approval of the 2024-2029 National Outer Continental Shelf Oil and Gas Leasing Program that includes a maximum of three potential GOM oil and gas lease sales during this period. The BOEM noted it is “the fewest oil and gas lease sales in history,” and that it was adopting those sales in response to a provision of the IRA that tied offshore wind leasing to a minimum level of offshore oil and gas leasing until 2032.

Regarding onshore federal oil and gas leasing, the BLM in June 2022 resumed lease sales on a limited scale that excluded 80% of the planned acreage following environmental review, and at a higher royalty rate, after the Biden Administration’s pause of leasing through an executive order was enjoined. In July 2023, the BLM proposed regulations to revise its oil and gas leasing process to implement the IRA’s increases in royalty rates, rental rates and minimum bids, but also to prioritize leasing in areas with known resource potential and in proximity to existing oil and gas infrastructure and avoid leasing in areas with competing uses such as recreation, wildlife habitat, conservation and historical and cultural resources, increased bonding requirements for leasing, development and production, new reporting and operational requirements for temporarily abandoned wells and potentially change the term of an approved application for permit to drill. The BLM is expected to promulgate final regulations on its leasing process in 2024. In July 2023, the U.S. Department of the Interior announced a proposed rule revising bonding requirements, royalty rates and minimum bids for the onshore federal oil and gas leasing program. If the foregoing regulations are finalized, Occidental’s subsidiaries could incur increased federal royalties and face restrictions on future potential drilling sites or infrastructure on federal lands.

In June 2022, advocacy groups filed a petition in the U.S. District Court for the District of Columbia against the BLM seeking to invalidate numerous drilling permits for oil and gas wells on federal lands in New Mexico and Wyoming, and potentially other states, that were approved by the BLM under the Biden Administration, including certain permits obtained by Occidental subsidiaries. The plaintiffs allege that the BLM failed to comply with various statutes, including NEPA, the ESA and the Federal Land Policy and Management Act, by not adequately addressing GHG emissions and climate change in the environmental documents underlying the approvals. Occidental, other producers and multiple trade associations have intervened. In November 2023, the U.S. District Court for the District of Columbia dismissed the case. Plaintiffs have filed an appeal. Similar cases challenge permits issued to other operators with respect to the BLM’s consideration of GHG and other air emissions under NEPA and other statutes.

In January 2023, the White House Council on Environmental Quality (CEQ) released interim guidance directing federal agencies to consider climate change-related effects as part of the NEPA review process. In June 2023, the President signed the Fiscal Responsibility Act (FRA), which amended NEPA to streamline the application and documentation process for agency environmental reviews, set time limits on those reviews, and narrow the scope of agency consideration. In July 2023, the CEQ proposed amendments to NEPA’s implementing regulations, which include defining “effects” to include “climate change-related effects.” The CEQ is expected to issue final NEPA regulations to implement the FRA’s amendment and its final NEPA guidance for consideration of GHG emissions and climate change. Litigation over NEPA environmental reviews by advocacy groups and associated delays in federal agency actions have significantly delayed or increased costs, impacted financing, or led to the cancellation of proposed domestic energy, manufacturing and infrastructure projects, and such litigation and delays could adversely affect such projects in the future, including those involving Occidental or its subsidiaries, joint ventures or customers.

Although the foregoing revisions to federal onshore and offshore leasing, the CEQ’s interim guidance and proposed NEPA regulations, and related lawsuits have not affected to date Occidental’s existing production or planned 2024 drilling and completions activity, restrictions, uncertainty, or litigation regarding federal lease sales and permits and associated royalty and regulatory requirements could impact the future ability to develop resources efficiently on federal lands or in projects that require federal actions on private or state lands.

Significant areas of the Permian Basin in West Texas and Southeast New Mexico are subject to current or proposed land use restrictions under the ESA. On June 30, 2023, the U.S. Fish and Wildlife Service (FWS) proposed listing the Dunes Sagebrush Lizard as an endangered species under the ESA. In November 2022, the FWS published a final rule listing the Lesser Prairie Chicken as endangered. Although Occidental has entered into voluntary conservation agreements with respect to these and other species and their associated habitat in the Permian Basin, listing of such species may impose significant operational requirements and costs and increase the potential for litigation and enforcement actions. In July 2023, the NMFS proposed a critical habitat designation for the Rice’s whale in the GOM, which the NMFS intends to finalize in 2024 pursuant to a settlement agreement with advocacy groups. Under this designation the NMFS may seek to impose

						RISK FACTORS

conditions on offshore oil and gas development and vessel activity that supports such development, which could affect Occidental’s exploration, development and operations in the GOM.

Certain states where Occidental's subsidiaries conduct oil and gas operations have adopted or proposed significant land use and permitting laws and regulations that would impose siting requirements or “setbacks” on certain oil and gas drilling locations based on the distance of a proposed well pad to occupied structures, require additional permitting, notification and monitoring requirements for various oil and gas drilling, completions, hydraulic fracturing and production operations or various types of wells and facilities, limit leasing or use of state lands or increase royalty rates, rental rates and fees for such use, increase bonding, plugging and abandonment, and reclamation requirements, and impose other operational restrictions. While, as of December 31, 2023, Occidental's subsidiaries maintained a significant inventory of permits and permit applications with applicable regulatory agencies for a substantial portion of their planned 2024 drilling and completions activity, any significant regulatory delays could result in changes to the Company’s development program and its ability to establish new proved undeveloped locations by meeting the SEC’s “reasonably certain” threshold for adding PUD reserves.

Texas and New Mexico have experienced an increase in seismic activity in recent years, with events measuring magnitude 4 or greater in each state. In 2021, both states issued guidelines for operators to prevent or mitigate seismic activity, focused on produced water disposal wells. These guidelines also require operators to implement response plans for activities within agency-designated seismic response areas (SRAs). These states have curtailed water disposal and suspended disposal permits in SRAs, particularly in deep disposal wells. Occidental does not operate deep disposal wells in the SRAs established by the state agencies to date, and its shallow disposal wells have been authorized to operate at agency-approved volumes, pressures or injection rates. Occidental also utilizes central water treatment and recycling facilities that reduce the need for disposal of produced water. Certain contractors that dispose of Occidental’s surplus produced water have been affected by agency actions in SRAs, but to date have found alternatives that enable continued disposal. Actions by agencies and companies to shift produced water disposal to shallower disposal zones is believed to alleviate seismic activity, but can increase the pressure in those shallower zones, which may increase costs of drilling and well construction through those zones or affect the ability to access underlying oil and gas formations. While Occidental’s ability to drill and complete wells or to dispose of surplus produced water has not been significantly affected by these seismic guidelines to date, increased seismicity, or responses to seismic events by agencies and companies such as curtailing or relocating disposal, could impact the location, timing and cost of Occidental’s development program and existing operations in or near SRAs.

In 2016, the Toxic Substances Control Act (TSCA) was amended to expand the EPA’s authority to evaluate and regulate new and existing chemicals. The EPA is currently evaluating, or developing regulations with respect to, certain chemicals that OxyChem produces or uses in its chemical manufacturing operations. In 2022, the EPA issued a proposed rule with respect to one chemical used in OxyChem’s manufacturing operations and several other chemicals that OxyChem produces and sells. The EPA is expected to issue final regulations under the 2016 TSCA amendments with respect to these chemicals in 2024. The EPA is also soliciting public comment on commencing risk evaluations of additional chemicals that OxyChem manufactures or uses, including vinyl chloride, as well as changes to its TSCA procedures for data collection and risk evaluation. Depending on the scope of any such final regulations, or of future TSCA regulations, OxyChem’s and its customers’ ability to use certain chemicals or to manufacture or sell certain of its products could be restricted or phased out and OxyChem’s costs could increase.

In addition, Occidental has experienced and may continue to experience adverse consequences, such as risk of loss or production limitations, because certain of its international operations are located in countries that may be affected by political instability, nationalizations, corruption, armed conflict, terrorism, insurgency, civil unrest, security problems, labor unrest, OPEC production restrictions, equipment import restrictions and sanctions. Exposure to such risks may increase if a greater percentage of Occidental’s future oil and gas production or revenue comes from international sources.

Climate change and further regulation of GHG and other air emissions may adversely affect Occidental’s businesses and results of operations.

Continuing political, social and industry attention to climate change has resulted in both existing and pending international agreements and national, regional and local legislation and regulatory programs to reduce GHG emissions. The Biden Administration has identified climate change as a priority and has issued executive orders and proposed regulations to prohibit or restrict oil and gas development activities in certain areas. In addition to the government actions described above, in February 2021, the Biden Administration established an Interagency Working Group (IWG) to assign a price to the impact of each metric ton of GHG emissions, called the social costs of GHGs (SC-GHG), that federal agencies could use to assess the benefits of more stringent GHG regulations and policy support for low-carbon projects. The IWG set an interim value of $51 per metric ton of CO2 emissions in 2020 at a 3% discount rate, which has been subject to legal challenge. Challenges to the interim value have thus far been rejected in two federal appellate courts. In September 2023, based on recommendations from the IWG, the Biden Administration directed federal agencies to expand the use of SC-GHG estimates to assess the benefits of federal programs and regulations in their budgeting, discretionary grants and procurement, and to apply the SC-GHG in calculating penalties in enforcement proceedings and in environmental reviews under NEPA for use in permitting decisions and other regulatory activities. In November 2023, the EPA utilized a range of SC-GHG significantly higher than the IWG’s interim value to support its final regulation of methane and volatile organic compounds (VOCs) described below. In December 2023, the Administration released a memorandum from the IWG inviting federal agencies to “use their professional judgment” to determine which SC-GHG estimates they would apply in a particular

						RISK FACTORS

context. Collectively, these efforts have the potential to significantly increase both the policy support for low-carbon ventures and the scope of regulations that apply to Occidental’s industry segments and facilities, including those described below.

In June 2021, Congress and President Biden reinstated the methane provisions of the EPA’s 2012 and 2016 regulations, an action that Occidental supported. In November 2021 and November 2022, the EPA respectively proposed for public comment a framework for expanded federal regulation of methane and VOC emissions and the proposed regulations to cover a broader set of new upstream and midstream oil and gas operations, as well as various existing operations. In December 2023, the EPA issued its final new source performance standards (NSPS) to directly regulate methane and VOC emissions from nearly all U.S. onshore oil and gas wells and facilities that were new, modified or reconstructed after December 6, 2022, and Emissions Guidelines (EG) that are similar to federal NSPS for states to apply to existing oil and gas wells and facilities through state implementation plans requiring EPA approval and required to take effect no later than 2029. These regulations expand leak detection and repair programs, require rapid reporting and correction of larger emission sources the EPA calls “super emitters”, require additional emission controls for new and existing wells and facilities and certain types of activities, phase out routine flaring, require replacement or conversion of certain emitting equipment such as gas-driven pneumatic controllers and pumps, and encourage the use of advanced technologies to detect and measure methane emissions. In November 2022, the BLM also proposed regulations to restrict venting and flaring from oil and gas operations on federal lands. A final rule has yet to be issued.

In June 2022, the EPA proposed to amend its GHG Reporting Rule with respect to oil and gas operations and several other industry sectors. In August 2022, the IRA also directed the EPA to update its GHG Reporting Rule to require greater use of measurements or empirical data, instead of emissions factors. Accordingly, the EPA proposed regulations in June 2023 to amend Subpart W that applies to most U.S. oil and gas facilities to incorporate additional oil and gas equipment and sources, including a category of “other larger release events”, revise existing emissions estimation methodologies and calculations, including the global warming potential (GWP) of methane and other GHGs, and increase data collection, particularly for new or modified emissions sources. The EPA is expected to promulgate the final Subpart W regulations in 2024, and to apply the revised GWPs to 2024 emissions, with the other changes applicable to emissions starting in 2025. These proposed amendments could increase Occidental’s reported estimated emissions from certain sources or types of equipment in its U.S. oil and gas operations. In April 2023, the EPA released a supplemental proposed rule that would revise the GWP and several other subparts of the GHG Reporting Rule, including the reporting that Occidental submits as a CO2 supplier and for the injection of CO2, and add a new reporting category for sequestration of CO2 associated with enhanced oil recovery. The EPA is expected to promulgate these final GHG regulations in 2024 with the same effective date as expected for the final Subpart W regulations.

The IRA also established an escalating methane emissions charge that the EPA will impose, subject to certain statutory exemptions, on upstream and midstream oil and gas facilities subject to reporting under Subpart W of the GHG Reporting Rule per metric ton of methane emissions above specified intensity thresholds for applicable sectors of the oil and gas industry. The charge starts at $900 per metric ton of methane emitted above applicable thresholds in 2024, and increases to $1,200 per ton in 2025, and $1,500 per ton in 2026 and thereafter. In January 2024, the EPA proposed for public comment regulations to implement the methane emissions charge and calculate the charge to be paid by owners or operators of covered oil and gas facilities.

The EPA proposed several other regulations of GHG emissions in 2023 that it is expected to finalize in 2024, including NSPS and EG for electric generating units, multi-pollutant emissions standards for light- and medium-duty vehicles and GHG emissions standards for heavy-duty vehicles.

As part of its development of five proposed sequestration hubs, 1PointFive has filed multiple permit applications with the EPA for Class VI CO2 sequestration wells in Louisiana and Texas. These permits are necessary to construct and operate sequestration hubs. In December 2023, the EPA granted Louisiana primary authority for permitting and oversight of Class VI sequestration wells, and 1PointFive expects that the Louisiana Department of Natural Resources will assume permitting authority over its pending applications in the state in February 2024. Texas has also applied for such authority, a process which is expected to take up to two years, so 1PointFive expects that the EPA will continue to process its pending Class VI permit applications in Texas. Denial of Class VI permits or significant delays in their issuance could adversely affect the cost, timing, financing and competitiveness of 1PointFive’s planned hub development.

Several state governments have also established rules aimed at reducing GHG emissions, some including GHG cap and trade programs and others directly regulating equipment that emits GHGs, including methane, and other compounds. Most of these cap and trade programs work by requiring major sources of emissions, such as electric power plants, or major producers of fuels, including refineries and natural gas processing plants, to acquire and surrender emission allowances. Other U.S. states where Occidental operates, including Colorado, New Mexico and Texas, adopted or proposed new regulations, policies or strategies in recent years that increase inspection, recordkeeping, reporting, enforcement and controls on flaring, venting and equipment that emit methane and other compounds at oil and gas facilities. In certain instances, these states anticipate tying the processing and active status of oil and gas permits, including drilling permits, to air emissions and compliance. For example, Colorado has established GHG intensity targets for DJ Basin operators in 2025, 2027 and 2030, which Occidental currently meets. In October 2023, California enacted legislation addressing the disclosure of GHG emissions, climate-related risks, certain environmental claims and the use or sale of voluntary carbon offsets.

Additionally, in March 2022, the SEC proposed climate disclosure rules that would require public companies to significantly increase disclosure of GHG emissions and strategies, targets, costs and risks associated with climate change and the energy transition, which the SEC is expected to finalize in 2024. The DOE is implementing several environmental and climate-focused initiatives, including funding low-carbon and emissions reduction projects and setting national energy efficiency standards for residential, commercial and industrial appliances and equipment that promote electrification.

Global efforts have been made and continue to be made in the international community toward the adoption of international treaties or protocols that would address global climate change issues and impose reductions of hydrocarbon-

						RISK FACTORS

based fuels, including plans developed in connection with the Paris climate conference in December 2015, the Katowice climate conference in December 2018 and the United Nations’ climate change conferences since 2021. In January 2023, the European Union (EU) enacted the Corporate Sustainability Reporting Directive, which will require sustainability reporting across a broad range of environmental, social, and governance (ESG) topics for both EU and certain non-EU companies. Numerous countries have also begun proposing climate-related frameworks aligned with the standards of the International Sustainability Standards Board.

These and other government actions relating to GHG and other air emissions are expected to require Occidental to incur increased operating and maintenance costs including higher rates charged by service providers and costs to purchase, operate and maintain emissions control systems, acquire emission allowances, pay taxes or fees for methane or carbon emissions and comply with new regulatory or reporting requirements; and they could prevent Occidental from conducting oil and gas development activities in certain areas. They could also promote the use of alternative sources of energy and thereby decrease demand for oil, NGL, natural gas and other products that Occidental’s businesses produce, and could also materially impact OLCV’s current or future operations and strategy. Any such legislation or regulatory programs could also increase the cost of consuming, and thereby reduce demand for, oil, NGL, natural gas or other products produced by Occidental’s businesses and lower the value of its reserves. Consequently, government actions designed to reduce GHG emissions could cause Occidental to make changes with respect to its business plan, operations and assets that may impact its business and financial performance and could have an adverse effect on its businesses, financial condition, results of operations, cash flows and reserves.

It is difficult to predict the timing, certainty and scope of such government actions and their ultimate effect on Occidental, which could depend on, among other things, the type and extent of GHG emissions reductions required, the availability and price of emission allowances or credits, the availability and price of alternative fuel sources, the energy sectors covered. Occidental’s ability to recover the costs incurred through its operating agreements or the pricing of its oil, NGL, natural gas and other products and whether service providers are able to pass increased costs through to Occidental.

Compliance costs and liabilities associated with health, safety and environmental laws and regulations could have a material adverse effect on Occidental’s or its subsidiaries’ businesses, financial condition and results of operations.

Occidental and its subsidiaries and their respective operations are subject to numerous laws and regulations relating to public and occupational health, safety and environmental protection, including those governing GHG and other air emissions, water use and discharges, waste management, environmental remediation and protection of wildlife and ecosystems. The requirements of these laws and regulations are becoming increasingly complex, stringent and expensive to implement. Costs of compliance with these laws and regulations are significant and can be unpredictable. These laws sometimes provide for strict liability for events that pose an impact or threat to public health and safety or to the environment, including for funding or performance of remediation and, in some cases, compensation for alleged personal injury, property damage, natural resource damages, punitive damages, civil penalties, injunctive relief and government oversight costs. Strict liability can render Occidental or its subsidiaries liable for damages without regard to their degree of care or fault. Some environmental laws provide for joint and several strict liability for remediation of spills and releases of hazardous substances or materials, and, as a result, Occidental or its subsidiaries could be liable for the actions of others.

Occidental and its subsidiaries use and generate hazardous substances or materials in their respective operations. In addition, many of their current and former properties are, or have been, used for industrial purposes. Accordingly, Occidental or its subsidiaries have been, and could become, subject to significant liabilities relating to the investigation, assessment and remediation of potentially contaminated properties and to claims alleging personal injury or property damage as a result of exposures to, or releases of, hazardous substances or materials. For example, as of the date of this filing, Occidental believes its range of reasonably possibly additional losses of its subsidiaries for environmental remediation beyond those amounts currently recorded could be up to $2.6 billion on a consolidated basis. For additional discussion of such matters, see Note 12 – Environmental Liabilities and Expenditures and Note 13 - Lawsuits, Claims, Commitments and Contingencies in the Notes to Consolidated Financial Statements in Part II Item 8 of this Form 10-K.

In addition, stricter enforcement or changing interpretations of existing laws and regulations, the enactment of new laws and regulations, the discovery of previously unknown contamination or the imposition of new or increased requirements could require Occidental or its subsidiaries to incur costs or become the basis for new or increased liabilities that could have a material adverse effect on their respective businesses, financial condition and results of operations.

Occidental’s businesses may experience catastrophic events.

The occurrence of severe weather events such as hurricanes, floods, freezes and heat waves, droughts, earthquakes or other acts of nature, pandemics, well blowouts, fires, explosions, pipeline ruptures, chemical releases, oil releases, including maritime releases, releases into navigable waters and groundwater contamination, material or mechanical failure, power outages, industrial accidents, physical or cyber attacks, abnormally pressured or structured formations and other events that cause operations to cease or be curtailed may negatively affect Occidental’s businesses and the communities in which it operates. Coastal operations are particularly susceptible to disruption from severe weather events. The foregoing events may present acute risks such as specific storms or wildfires or chronic risks such as sea level rise or water scarcity. Any of these risks could adversely affect Occidental’s ability to conduct operations or result in substantial losses as a result of:


14			OXY 2023 FORM 10-K


						RISK FACTORS

■Damage to and destruction of property and equipment, including property and equipment owned by third parties which its operations rely upon;

■Impacts to Occidental’s workforce and local communities;

■Damage to natural resources;

■Pollution and other environmental damage, including spillage or mishandling of recovered chemicals or fluids;

■Regulatory investigations, fines and penalties;

■Loss of well location, acreage, expected production and related reserves;

■Suspension or delay of its operations;

■Substantial liability claims; and

■Significant repair and remediation costs that increase its breakeven economics.

Third-party insurance may not provide adequate coverage or Occidental or its subsidiaries may be self-insured with respect to the related losses. In addition, under certain circumstances, Occidental or its subsidiaries may be liable for environmental conditions on properties that they currently own, lease or operate that were caused by previous owners or operators of those properties. As a result, Occidental or its subsidiaries may incur substantial liabilities to third parties or government entities for environmental matters for which they do not have insurance coverage, which could reduce or eliminate funds available for exploration, development, acquisitions or other investments in their respective businesses, or cause them to incur losses.

Risks related to Occidental’s businesses and operations

Volatile global and local commodity pricing strongly affect Occidental’s results of operations.

Occidental’s financial results correlate closely to the prices it obtains for its products, particularly oil and, to a lesser extent, NGL, natural gas and its chemical products.

Prices for oil, NGL and natural gas fluctuate widely. Historically, the markets for oil, NGL and natural gas have been volatile and may continue to be volatile in the future. If the prices of oil, NGL or natural gas continue to be volatile or decline, Occidental’s operations, financial condition, cash flows, level of expenditures and the quantity of estimated proved reserves that may be attributed to its properties may be materially and adversely affected. Prices are set by global and local market forces which are not in Occidental’s control. These factors include, among others:

■Worldwide and domestic supplies of, and demand for, oil, NGL, natural gas and refined products;

■The cost of exploring for, developing, producing, refining and marketing oil, NGL, natural gas and refined products;

■Operational impacts such as production disruptions, technological advances and regional market conditions, including available transportation capacity and infrastructure constraints in producing areas;

■Changes in weather patterns and climate;

■The impacts of the members of OPEC and non-OPEC member-producing nations that may agree to and maintain production levels;

■The ongoing global impact of the Russia-Ukraine war and conflicts in the Middle East;

■The worldwide military and political environment, including uncertainty or instability resulting from an escalation or outbreak of armed hostilities or acts of terrorism in the United States or elsewhere;

■The price and availability of and demand for alternative and competing fuels and emissions reducing technology;

■Technological advances affecting energy consumption and supply;

■Government policies and support and market demand for low-carbon technologies;

■Domestic and international government regulations and taxes, including those that restrict the export of hydrocarbons;

■Shareholder activism or activities by non-governmental organizations to restrict the exploration, development and production of oil, NGL and natural gas;

■Additional or increased nationalization and expropriation activities by international governments;

■The impact and uncertainty of world health events, including pandemics and epidemics;

■The effect of releases from or replenishment of the U.S. Strategic Petroleum Reserve;

■Volatility in commodity markets;

■The effect of energy conservation efforts; and

■Global inventory levels and general economic conditions, including potential economic slowdowns or recessions, domestically or internationally.

						RISK FACTORS

The long-term effects of these and other conditions on the prices of oil, NGL, natural gas and chemical products are uncertain and there can be no assurance that the demand or pricing for Occidental’s products will follow historic patterns in the near term. Prolonged or substantial decline, or sustained market uncertainty, in these commodity prices may have the following effects on Occidental’s businesses:

■Adversely affect Occidental’s financial condition, results of operations, liquidity, ability to reduce debt, access to and cost of capital, and ability to finance planned capital expenditures or planned acquisitions, pay dividends and repurchase shares;

■Reduce the amount of oil, NGL and natural gas that Occidental can produce economically;

■Cause Occidental to delay or postpone some of its capital projects;

■Reduce Occidental’s revenues, operating income or cash flows;

■Reduce the amounts of Occidental’s estimated proved oil, NGL and natural gas reserves;

■Reduce the carrying value of Occidental’s oil and natural gas properties due to recognizing impairments of proved properties, unproved properties and exploration assets;

■Reduce the standardized measure of discounted future net cash flows relating to oil, NGL and natural gas reserves; and

■Adversely affect the ability of Occidental’s partners to fund their working interest capital requirements.

Generally, Occidental’s historical practice has been to remain exposed to the market prices of commodities. As of December 31, 2023, there were no active commodity hedges in place. Management may choose to put hedges in place in the future for oil, NGL and natural gas commodities. Commodity price risk management activities may prevent Occidental from fully benefiting from price increases and may expose it to regulatory, counterparty credit and other risks.

The prices obtained for Occidental’s chemical products correlate to the strength of the United States and global economies, as well as chemical industry expansion and contraction cycles. Occidental also depends on feedstocks and energy to produce chemicals, which are commodities subject to significant price fluctuations.

Occidental may experience delays, cost overruns, losses or other unrealized expectations in development efforts and exploration activities.

Oil, NGL and natural gas exploration and production activities are subject to numerous risks beyond Occidental’s control, including the risk that drilling will not result in commercially viable oil, NGL and natural gas production. In its development and exploration activities, Occidental bears the risks of:

■Equipment failures;

■Construction delays;

■Escalating costs for, competition for, shortages of or delays in services, materials, supplies, equipment or labor;

■Increasing prices as a result of broad inflation;

■Property or border disputes;

■Disappointing drilling results or reservoir performance;

■Title problems and other associated risks that may affect its ability to profitably grow production, replace reserves and achieve its targeted returns;

■Actions by third-party operators of its properties;

■Delays imposed by or resulting from compliance with permits, laws, regulations or litigation and costs of drilling wells on lands subject to complex development terms and circumstances; and

■Oil, NGL and natural gas gathering, transportation and processing availability, restrictions or limitations.

Exploration is inherently risky and is subject to delays, misinterpretation of geologic or engineering data, unexpected geologic conditions or finding reserves of disappointing quality or quantity, which may result in significant losses.

Claims, litigation, government investigations and other proceedings may adversely affect Occidental’s businesses, consolidated financial position, results of operations and cash flows.

Occidental is subject to actual and threatened claims, litigation, reviews, investigations, and other proceedings, including proceedings by governments and regulatory authorities, involving a wide range of issues, including regarding its drilling, manufacturing or production processes, commercial disputes, environmental compliance, public health and safety and taxes. The outcomes of these matters are inherently unpredictable and subject to significant uncertainties. Determining legal reserves or possible losses from such matters involves judgment and may not reflect the full range of uncertainties and unpredictable outcomes. Until the final resolution of such matters, Occidental may be exposed to losses in excess of the amount recorded, and such amounts could be material. Should any of its estimates and assumptions change or prove to have been incorrect, it could have a material adverse effect on Occidental’s businesses, consolidated financial position, results of operations and cash flows.

For additional discussion of some of these matters, see Note 12 – Environmental Liabilities and Expenditures and Note 13 - Lawsuits, Claims, Commitments and Contingencies in the Notes to Consolidated Financial Statements in Part II Item 8 of this Form 10-K.

						RISK FACTORS

Disruptions in the political, regulatory, economic, and social environments of the countries in which Occidental operates could adversely affect its reputation, financial condition, results of operations and cash flows.

Occidental’s non-U.S. operations accounted for approximately 16% of its consolidated revenue in 2023, 15% in 2022 and 16% in 2021. Operations in non-U.S. countries with varying degrees of political, legal and economic stability expose Occidental to a wide range of developments that could result in contractual, legal or regulatory changes. Instability and unforeseen changes in any of the markets in which Occidental operates could result in business disruptions or operational challenges that may adversely affect the demand for Occidental’s products and services, or its reputation, financial condition, results of operations or cash flows. These factors include, but are not limited to, the following:

■ Uncertain or volatile political, social, and economic conditions;

■ Social unrest, acts of terrorism, war, or other armed conflict;

■ Public health crises and other catastrophic events, such as pandemics;

■ Confiscatory taxation or other adverse tax policies;

■ Theft of, or lack of sufficient legal protection for, proprietary technology and other intellectual property;

■ Unexpected changes in legal and regulatory requirements, including changes in interpretation or enforcement of existing laws;

■ Restrictions on the repatriation of income or capital;

■ Currency exchange controls;

■ Inflation; and

■ Currency exchange, rate fluctuations and devaluations.

In addition, the U.S. government has the authority to prevent or restrict Occidental from doing business in foreign jurisdictions or with certain parties. These restrictions and similar restrictions imposed by foreign governments have in the past limited Occidental’s ability to operate in, or gain access to, opportunities in various jurisdictions. Changes in domestic and international policies and regulations may also restrict the Company’s ability to obtain or maintain licenses or permits necessary to operate in foreign jurisdictions, including those necessary for drilling and development of wells. Similarly, the declaration of a “climate emergency” could result in actions to limit exports of Occidental’s products and other restrictions. Any of these actions could adversely affect its businesses or results of operations.

Occidental’s oil and gas business operates in highly competitive environments, which affect, among other things, its ability to source production and replace reserves.

The exploration and production of oil, NGL and natural gas is a highly competitive business. Occidental has many competitors (including national oil companies), some of which: (i) are larger and better funded; (ii) may be willing to accept greater risks; (iii) have greater access to capital; (iv) have substantially larger staffs; or (v) have special competencies. Results of operations, reserves replacement and the level of oil and gas production depend, in part, on Occidental’s ability to profitably acquire additional reserves. Competition for access to reserves may make it more difficult to find attractive investment opportunities or require delay of reserve replacement efforts. Further, during periods of low product prices, any cash conservation efforts may delay production growth and reserve replacement efforts. Also, there is substantial competition for capital available for investment in the oil and natural gas industry. Occidental’s failure to acquire properties, potentially grow production, replace reserves and attract and retain qualified personnel could have a material adverse effect on its cash flows and results of operations. Further, as its competitors use or develop new technologies, Occidental may be placed at a competitive disadvantage, and competitive pressures may force its to implement new technologies at a substantial cost.

In addition, Occidental’s acquisition activities carry risks that it may: (i) not fully realize anticipated benefits due to less-than-expected reserves or production or changed circumstances, such as declines in oil, NGL and natural gas prices; (ii) bear unexpected integration costs or experience other integration difficulties; (iii) experience share price declines based on the market’s evaluation of the activity; or (iv) be subject to liabilities that are greater than anticipated.

Occidental’s oil and gas reserves are estimates based on professional judgments and may be subject to revision.

Reported oil and gas reserves are an estimate based on periodic review of reservoir characteristics and recoverability, including production decline rates, operating performance and economic feasibility at the prescribed weighted average commodity prices, future operating costs and capital expenditures, workover and remedial costs, assumed effects of regulation by government agencies, the quantity, quality and interpretation of relevant data, taxes and availability of funds. The procedures and methods for estimating the reserves by Occidental’s internal engineers were reviewed by independent petroleum consultants. The process of estimating oil and natural gas reserves, however, is complex and requires significant decisions and assumptions in the evaluation of available geological, geophysical, engineering and economic data for each reservoir and is therefore inherently uncertain. Actual production, revenues, expenditures, oil, NGL and natural gas prices and taxes with respect to Occidental’s reserves may vary from estimates and the variance may be material. Additional regulation around GHG emissions and future costs related to a less carbon-intensive economy could result in a shortened


OXY 2023 FORM 10-K			17


						RISK FACTORS

oil and gas reservoir reserve life as the underlying reserves become uneconomical. If Occidental were required to make significant negative reserve revisions, its results of operations and stock price could be adversely affected.

In addition, the discounted cash flows included in this Form 10-K should not be construed as the fair value of the reserves attributable to Occidental’s properties. The estimated discounted future net cash flows from proved reserves are based on an unweighted arithmetic average of the first-day-of-the-month price for each month within the year in accordance with SEC regulations. Actual future prices and costs may differ materially from SEC regulation-compliant prices and costs used for purposes of estimating future discounted net cash flows from proved reserves. Also, actual future net cash flows may differ from these discounted net cash flows due to the amount and timing of actual production, availability of financing for capital expenditures necessary to develop Occidental’s undeveloped reserves, supply and demand for oil, NGL and natural gas, increases or decreases in consumption of oil, NGL and natural gas and changes in government regulations or taxation.

Occidental’s future results could be adversely affected if it is unable to execute new business strategies effectively.

Occidental’s results of operations depend on the extent to which it can execute new business strategies effectively relative to both the societal transition to a less carbon-intensive economy and laws, regulations and government and private actions regarding the environment and climate change. Occidental’s strategies seek to advance its goals of achieving net-zero emissions (i) from its operations and energy use before 2040, with an ambition to do so before 2035, and (ii) from its total carbon inventory, including the use of its sold products, with an ambition to do so before 2050. Occidental’s strategies and goals are subject to business, economic and competitive uncertainties and contingencies, many of which are beyond its control. Additionally, Occidental may be forced to develop or implement new technologies at substantial costs to achieve its strategies. Effective execution of these goals may require substantial new capital, which might not be available to Occidental in the amounts or at the times expected. In addition, raising such capital may increase its leverage or overall costs of doing businesses. These uncertainties and costs could cause Occidental to not be able to fully implement or realize the anticipated results and benefits of its business strategies.

Certain of Occidental’s emissions goals are dependent upon the successful implementation of new and existing technologies on an industrial scale. These technologies are in various stages of development or implementation and may require more capital, or take longer to develop, than currently expected. Further, these carbon management technologies are in competition with technologies being developed by other companies. The carbon management solutions are not well established and, while Occidental believes it has access to the technologies and the expertise necessary to develop these solutions on an industrial scale, Occidental may not ultimately succeed in doing so and in achieving its GHG emissions reduction and net-zero goals.

Occidental’s strategy to include carbon management in its product line is also dependent upon demand for carbon sequestration and related CO2 removal credits, offsets or other attributes. If this market does not develop, or if the regulatory environment does not support carbon management activities, Occidental may not be successful in this industry.

Occidental’s aspirations, goals and initiatives related to carbon management and overall sustainability expose it to numerous risks.

Occidental continues to develop new technologies and strategies to position it to meet its emissions reduction and net-zero goals. Occidental’s efforts to research, establish, accomplish and accurately report on its emissions goals, targets and strategies expose it to numerous operational, reputational, financial, legal, technological, implementation and other risks. Occidental’s ability to reach its target emissions is subject to a multitude of factors and conditions, many of which are out of its control. Examples of such factors include evolving government regulation and voluntary protocols for reporting or verification of emissions, capture or sequestration, the potential for jurisdictions in which it operates to enact opposing or incompatible regulations, the pace of changes in technology, the successful development and deployment of existing or new technologies and business solutions on a commercial scale, the availability, timing and cost of equipment, manufactured goods and services, and the availability of requisite financing and federal and state incentive programs.

In addition, historical, current and forward-looking sustainability-related statements may be based on standards for measuring progress that are still developing, internal controls and processes that continue to evolve and assumptions that are subject to change in the future. As noted earlier, there are multiple proposed or recently adopted changes to various GHG reporting regulations and protocols, including from the EPA, the SEC, the GHG Protocol and certain countries and states, as well as for additional controls, fees or taxes on emissions. While Occidental has reported voluntarily on its net-zero pathway and associated goals and targets, as well as GHG emissions estimates, the SEC’s proposed rules would require both significant additional disclosure and integration of such disclosure directly into financial reporting processes. Occidental and numerous other stakeholders submitted comments to the SEC on the proposed rules. The SEC is expected to issue final rules in 2024. Given the potential significance of these changes for estimation, reporting and verification of GHG emissions, establishing and reporting on goals and targets, and estimating and disclosing costs of emissions reduction and the energy transition, Occidental may be required or elect to modify or update reported emissions and its current set of GHG goals and targets to reflect such new or changed regulations and protocols, although the Company currently expects to retain its overarching net-zero goals and to continue to implement emissions reduction plans that it believes will complement its investments in DAC, CCUS and other low-carbon technologies and infrastructure. As the nature, scope and complexity of environmental, social and governance (ESG) reporting, calculation methodologies, voluntary reporting


18			OXY 2023 FORM 10-K


						RISK FACTORS

standards and disclosure requirements expand and change, Occidental may have to undertake additional costs to control, assess and report on ESG metrics, especially to the extent applicable rules and standards are not harmonized or consistent.

Occidental may face increased scrutiny from the investment community, customers, political advocacy groups, other stakeholders and the media related to its emissions reduction and net-zero goals and strategies, and it may be unable to satisfy all stakeholders. If Occidental’s emissions goals and strategies to achieve them do not meet evolving investor or other stakeholder expectations or standards, Occidental’s reputation, ability to attract and retain employees and attractiveness as an investment, business partner, supplier or acquirer could be negatively impacted. Similarly, Occidental’s failure or perceived failure to fulfill its emissions goals and targets, to comply with ethical, health, safety, environmental, social, governance or other standards, regulations, or expectations, or to satisfy various reporting standards with respect to these matters effectively could have the same negative impacts and further expose Occidental to government enforcement actions and private litigation. Even if Occidental achieves its goals, targets and objectives, it may not realize all of the benefits that it expected at the time the goals were established.

There also have been efforts in the investment community, including investment advisers, financial institutions and certain sovereign wealth, pension and endowment funds, as well as political actors and other stakeholders, promoting divestment of fossil fuel equities, reducing access to capital markets and pressuring lenders to limit funding or increase the cost of lending to companies engaged in the extraction of fossil fuel reserves. Additionally, institutional lenders who provide financing to oil and gas companies have become more attentive to sustainable lending practices, and some of them may substantially reduce, or elect not to provide, funding for oil and gas companies. Customers and suppliers also may evaluate Occidental’s sustainability practices or require that it adopt certain sustainability policies as a condition of awarding contracts. Such environmental initiatives aimed at limiting climate change and reducing air emissions could adversely affect Occidental’s business activities, operations and ability to access capital, cause the market value of its securities to decrease or its cost of capital to increase, and adversely affect its reputation. At the same time, stakeholders and regulators have increasingly expressed or pursued divergent views, legislation and investment expectations with respect to sustainability, including the enactment or proposal of “anti-ESG” legislation or policies.

Finally, increasing attention to climate change risks has resulted in an increased possibility of government investigations and additional private litigation against Occidental without regard to causation or its contribution to the asserted damage, which could increase its costs or otherwise adversely affect its businesses. For example, governments and private parties are also increasingly filing lawsuits or initiating regulatory action alleging misrepresentation regarding climate change and other ESG-related matters and practices or a failure or lack of diligence to meet publicly stated sustainability or climate-related goals. Such lawsuits present a high degree of uncertainty regarding the extent to which energy companies face an increased risk of liability stemming from climate change or sustainability disclosures and practices.

Occidental has previously recorded impairments of its proved and unproved oil and gas properties and will continue to assess further impairments for these properties and other assets in the future.

Occidental has recorded impairments of its proved and unproved oil and gas properties resulting from prolonged declines in oil and gas prices and may record such impairments in the future. Past impairments included pre-tax impairment and related charges to both proved and unproved oil and gas properties and a lower of cost or net realizable value adjustment for crude inventory. If there is an adverse downturn of the macroeconomic conditions and if such downturn is expected to or does persist for a prolonged period of time, Occidental’s oil and gas properties may be subject to further testing for impairment, which could result in additional non-cash asset impairments. Such impairments could be material to the financial statements.

Occidental may subject its low-carbon initiatives, including related acquisitions, and investments in unconsolidated subsidiaries, to impairment testing. If Occidental and/or its subsidiaries are not successful in these development-stage initiatives, including DAC, CCUS and other low-carbon projects, investments and ventures, such impairments could be material to the financial statements.

Future costs associated with reducing emissions and carbon impacts, as well as impacts resulting from other risk factors described herein, could lead to impairments in the future, if such costs significantly increase Occidental’s breakeven economics.

Occidental uses water and sand and is required to dispose of produced water. Occidental’s inability to source water and sand, or dispose of produced water, could adversely affect its operations.

Water and sand are required for the exploration and production of oil and gas. Occidental’s ability to obtain water and sand for its operations may be affected by the price of water and sand, the availability of transportation and other market conditions. Additionally, some government authorities have restricted the use of water subject to their jurisdiction for hydraulic fracturing. If Occidental is unable to obtain water or sand to use in its operations, Occidental may be unable to economically produce oil and natural gas, which could have a material and adverse effect on its financial condition, results of operations and cash flows.

In addition, Occidental must dispose of the surplus fluids produced from oil and gas production operations, including produced water, directly or through the use of third-party vendors. The legal requirements related to the injection of produced water into a non-producing geologic formation are subject to change. Restrictions as a result of more stringent regulations or legal directives, potential litigation or other developments could materially impact Occidental’s ability to dispose of produced water, which could have a material adverse effect on its business, financial condition and results of operations.


OXY 2023 FORM 10-K			19


						RISK FACTORS

Occidental uses CO2 for its EOR operations. Occidental’s production from these operations may decline if Occidental is not able to obtain sufficient amounts of CO2.

Occidental’s CO2 EOR operations are critical to Occidental’s long-term strategy. Oil production from Occidental’s CO2 EOR projects depends largely on having access to sufficient amounts of naturally occurring or anthropogenic (human-made) CO2. Occidental’s ability to produce oil from its CO2 EOR projects would be hindered if the supply of CO2 were limited due to, among other things, problems with current CO2 producing wells and facilities, including compression equipment, catastrophic pipeline failure or the ability to economically purchase naturally occurring or anthropogenic CO2. This could have a material adverse effect on Occidental’s financial condition, results of operations or cash flows. Future oil production from its CO2 EOR operations is dependent on the timing, volumes and location of CO2 injection and, in particular, Occidental’s ability to obtain sufficient volumes of CO2. Market conditions may cause the delay or cancellation of the development of naturally occurring CO2 sources or construction of plants that produce anthropogenic CO2 as a byproduct that can be purchased, thus limiting the amount of CO2 available for use in Occidental’s CO2 EOR operations.

Occidental is exposed to cyber-related risks.

The oil and gas industry is increasingly dependent on information technology (IT) and industrial control systems (ICS) to conduct certain exploration, development and production activities. Occidental relies on digital and industrial control systems, related infrastructure, technologies and networks to run its businesses and to control and manage its oil and gas, chemicals, marketing and pipeline operations. Use of the internet, cloud services, mobile communication systems and other public networks exposes Occidental’s businesses and those of third parties with whom Occidental does business, and relies on for certain services including related to Occidental’s systems and data, to the risk of cyber attacks, which have escalated in recent years.

Information and industrial control technology system failures, network disruptions and breaches of data security could disrupt Occidental’s operations by causing delays, impeding processing of transactions and reporting financial results, or leading to the unintentional disclosure of company, partner, customer or employee information that could damage its reputation. A cyber attack on Occidental’s information or industrial control systems and related infrastructure, or those of its business associates or third-party service providers, could negatively impact Occidental’s operations in a variety of ways, including, but not limited to:

■Adversely impacting Occidental’s ability to compete for oil and natural gas resources;

■Resulting in delays and failure to reach the intended target or cause a drilling incident;

■Resulting in a loss of production or accidental discharge;

■Resulting in a disruption of the manufacturing and marketing of its products or a potential HSE hazard;

■Resulting in supply chain disruptions, which could delay or halt Occidental’s construction and development projects;

■Delaying or preventing Occidental from producing, transporting, processing and marketing its production;

■Slowing or halting commodities trading, thus preventing Occidental from marketing its production or engaging in hedging activities;

■Adversely impacting the natural gas market;

■Causing operational disruption;

■Causing a loss in production or a potential HSE hazard;

■Resulting in events of non-compliance which could then lead to regulatory fines or other penalties and legal liability; and

■Damaging Occidental’s reputation, subjecting it to potential financial or legal liability, regulatory fines and penalties and requiring it to incur significant costs, including compliance costs, costs to repair or restore its systems and data or to take other remedial steps.

There can be no assurance that Occidental’s cybersecurity measures, or the efforts of its partners, will be sufficient to prevent or identify cybersecurity incidents. Although Occidental has implemented controls and multiple layers of security that it believes are reasonable to mitigate the risks of a cybersecurity incident, there can be no assurance that Occidental’s response will be successful or effectively address an incident on a timely basis. As a result of any of the foregoing, Occidental could suffer interruptions in its ability to manage its operations, which may adversely affect its business and financial results. In addition, Occidental may incur large expenditures to investigate or remediate, to recover data, to repair or replace networks or information systems or to protect against similar future events. Disruption to Occidental’s operations and damage to its reputation could materially adversely affect its financial position, results of operations or cash flows.

Moreover, laws and regulations governing cybersecurity and data privacy and the unauthorized disclosure of confidential or protected information pose increasingly complex compliance challenges and potential costs, and any failure to comply with these data privacy requirements or other applicable laws and regulations in this area could lead to a loss of sensitive information and result in significant regulatory or other penalties and legal liability.

While Occidental has experienced cyber attacks in the past, it has not suffered any material losses. However, if in the future Occidental’s cybersecurity measures are compromised or prove insufficient, the potential consequences to Occidental’s businesses and the communities in which it operates could be significant. As cyber attacks continue to evolve in magnitude and sophistication, Occidental may be required to expend additional resources in order to continue to enhance


20			OXY 2023 FORM 10-K


						RISK FACTORS

its cybersecurity measures and to investigate and remediate any digital and operational systems, related infrastructure, technologies and network security vulnerabilities, which would increase its costs. Occidental also may incur large expenditures to recover data, to repair or replace networks or information systems or to protect against similar future events. A system failure or data security breach, or a series of such failures or breaches, could have a material adverse effect on Occidental’s ability to manage its operations, which may adversely affect its businesses, financial condition, results of operations or cash flows.

Occidental’s oil and gas reserve additions may not continue at the same rate and a failure to replace reserves may negatively affect Occidental’s businesses.

Producing oil and natural gas reservoirs generally are characterized by declining production rates that vary depending upon reservoir characteristics and other factors. Unless Occidental conducts successful exploration or development activities, acquires properties containing proved reserves, or both, proved reserves will generally decline and negatively impact Occidental’s businesses. Occidental may not be successful in finding, developing or acquiring additional reserves, and its efforts may not be economic. Its ability to make the necessary capital investment to maintain or expand its asset base of oil and gas reserves would be limited to the extent cash flow from operations is reduced and external sources of capital become limited or unavailable. The value of Occidental’s securities and its ability to raise capital will be adversely impacted if it is not able to replace reserves that are depleted by production or replace its declining production with new production by successfully allocating annual capital to maintain its reserves and production base. Occidental expects infill development projects, extensions, discoveries and improved recovery to continue as main sources for reserve additions but factors such as geology, government regulations and permits, the effectiveness of development plans and the ability to make the necessary capital investments or acquire capital are partially or fully outside management’s control and could cause results to differ materially from expectations.

Occidental’s operations and financial results could be significantly negatively impacted by its offshore operations.

Occidental is vulnerable to risks associated with offshore operations that could negatively impact its operations and financial results. Certain Occidental subsidiaries conduct offshore operations primarily in the Gulf of Mexico and their operations and financial results are vulnerable to certain unique risks associated with operating offshore, including conditions relating to the following:

■Hurricanes and other adverse weather conditions;

■Geological complexities and water depths associated with such operations;

■Limited number of partners available to participate in projects;

■Oilfield service costs and availability;

■Compliance with HSE and other laws and regulations;

■Terrorist attacks or piracy;

■Remediation and other costs and regulatory changes resulting from oil spills, emissions or releases of hazardous substances or materials;

■Failure of equipment or facilities; and

■Response capabilities for personnel, equipment or environmental incidents.

In addition, certain Occidental subsidiaries conduct some of their exploration in deep waters (greater than 1,000 feet) where operations, support services and decommissioning activities are more difficult and costly than in shallower waters. The deep waters in the Gulf of Mexico, as well as international deep-water locations, lack the physical and oilfield service infrastructure present in shallower waters. As a result, deep-water operations may require significant time between a discovery and the time that Occidental can market its production, thereby increasing the risk involved with these operations.

Anadarko’s Tronox settlement may not be deductible for income tax purposes; Occidental may be required to repay the tax refund Anadarko received in 2016 related to the deduction of the Tronox settlement payment, which may have a material adverse effect on Occidental’s results of operations, liquidity and financial condition.

In April 2014, Anadarko and Kerr-McGee entered into a settlement agreement for $5.2 billion, resolving, among other things, all claims that were or could have been asserted in connection with the May 2009 lawsuit filed by Tronox against Anadarko and Kerr-McGee in the U.S. Bankruptcy Court for the Southern District of New York. After the settlement became effective in January 2015, Anadarko paid $5.2 billion and deducted this payment on its 2015 federal income tax return. Due to the deduction, Anadarko had a net operating loss carryback for 2015, which resulted in a tentative tax refund of $881 million in 2016.

The IRS audited Anadarko’s tax position regarding the deductibility of the payment and in September 2018 issued a statutory notice of deficiency rejecting Anadarko’s refund claim. Anadarko disagreed and filed a petition with the U.S. Tax Court to dispute the disallowance in November 2018. Trial was held in May 2023. Post-trial briefing is ongoing. Closing arguments are set for May 2024. Occidental expects to continue pursuing resolution. In accordance with Accounting Standards Codification (ASC) Topic 740’s guidance on the accounting for uncertain tax positions, as of December 31, 2023, Occidental had recorded no tax benefit on the tentative cash tax refund. If the payment is ultimately determined not to be deductible, Occidental would be required to repay the tentative refund received plus interest totaling approximately $2.0 billion as of December 31, 2023, which could have a material adverse effect on its liquidity and consolidated balance sheets.


OXY 2023 FORM 10-K			21


						RISK FACTORS

Occidental’s Consolidated Financial Statements include an uncertain tax position for the approximate repayment of $1.4 billion in federal taxes plus accrued interest of approximately $574 million. This amount is not covered by insurance. For additional information on income taxes, see Note 10 - Income Taxes in the Notes to Consolidated Financial Statements in Part II Item 8 of this Form 10-K.

Occidental’s indebtedness may make it more vulnerable to economic downturns and adverse developments in its businesses. Downgrades in Occidental’s credit ratings or future increases in interest rates may negatively impact Occidental’s cost of capital and ability to access capital markets.

Occidental’s level of indebtedness could increase its vulnerability to adverse changes in general economic and industry conditions, economic downturns and adverse developments in its businesses or limit Occidental’s flexibility in planning for or reacting to changes in its businesses and the industries in which it operates. From time to time, Occidental has relied on access to capital markets for funding. Occidental’s ability to obtain additional financing or refinancing will be subject to a number of factors, including general economic and market conditions such as rising interest rates, inflation or unstable or illiquid market conditions, Occidental’s performance, investor sentiment and Occidental’s ability to meet existing debt compliance requirements. Occidental’s ability to access credit and capital markets may be restricted at a time when it would like, or need, to access to those markets, which could constrain its flexibility to react to changing economic and business conditions. If Occidental is unable to generate sufficient funds from its operations to satisfy its capital requirements, including its existing debt obligations, or to raise additional capital on acceptable terms, Occidental’s businesses could be adversely affected. As of the date of this filing, Occidental’s long-term debt was rated BBB- by Fitch Ratings, Baa3 by Moody’s Investors Service and BB+ by Standard and Poor’s.

One of Occidental’s subsidiaries acts as the general partner of WES, a publicly traded master limited partnership, which may involve potential legal liability.

One of Occidental’s subsidiaries acts as the general partner of WES, a publicly traded master limited partnership. Its general partner interest in WES may increase the possibility that it could be subject to claims of breach of duties owed to WES, including claims of conflict of interest. Any such claims could increase Occidental’s costs and any liability resulting from such claims could have a material adverse effect on Occidental’s financial condition, operating results or cash flows.

Risks related to the CrownRock Acquisition

Occidental may not complete the CrownRock Acquisition within the anticipated timeframe or at all.

The completion of the CrownRock Acquisition is subject to a number of conditions, including the receipt of regulatory approvals. The failure to satisfy all of the required conditions could delay the completion of the CrownRock Acquisition for a significant period of time or prevent it from occurring at all. In addition, the terms and conditions of the required regulatory authorizations and consents for the CrownRock Acquisition that are granted, if any, may impose requirements, limitations or costs or place restrictions on the conduct of Occidental’s business after the transaction or materially delay the completion of the acquisition. A delay in completing the CrownRock Acquisition could cause Occidental to realize some or all of the benefits later than it otherwise expects to realize them if the CrownRock Acquisition were successfully completed within the anticipated timeframe, which could result in additional transaction costs or in other negative effects associated with uncertainty around completion of the acquisition.

In addition, Occidental has incurred, and will incur, transaction-related costs in connection with the CrownRock Acquisition, including legal, accounting, and other fees and costs relating to the CrownRock Acquisition. If Occidental is unable to complete the CrownRock Acquisition, Occidental will still incur, and will remain liable for, various transaction costs, which may be significant, without realizing the expected benefits of the CrownRock Acquisition.

Occidental may not achieve the intended benefits of the CrownRock Acquisition, and the CrownRock Acquisition may disrupt Occidental’s existing plans or operations.

There can be no guarantee that Occidental will be able to successfully integrate CrownRock or otherwise realize the expected benefits of the potential transaction, including being accretive to free cash flow. Difficulties in integrating CrownRock into Occidental may result in operational and other challenges, including the diversion of management’s attention from ongoing business concerns; the diversion of resources to integration processes; the retention of key CrownRock management and other employees; the retention of existing business and operational relationships, including customers, suppliers and other counterparties; the attraction of new business and operational relationships; the possibility of faulty assumptions underlying expectations regarding integration processes and associated expenses; the elimination of duplicative corporate or operational processes; potential limitations placed on Occidental’s business by regulatory authorities; the possibility that a failure to successfully integrate CrownRock into Occidental’s internal control over financial reporting could compromise the integrity of Occidental’s financial reporting; as well as unanticipated issues in integrating certain systems. An inability to realize the full extent of the intended benefits of the CrownRock Acquisition, and any delays encountered in the integration process, could have an adverse effect on Occidental’s revenues and its level of expenses and results of operations, which may adversely affect the value of Occidental’s common stock. In addition, the integration may result in additional or unforeseen expenses. Although Occidental expects the strategic benefits and additional free cash flow to offset incremental transaction-related costs over time, if Occidental is not able to adequately and effectively address


22			OXY 2023 FORM 10-K


						RISK FACTORS

integration challenges, it may be unable to successfully integrate operations or realize anticipated benefits of the integration of CrownRock.

Notwithstanding the due diligence investigation that Occidental performed in connection with its entry into the Purchase Agreement, CrownRock may have liabilities, losses, or other exposures for which Occidental does not have adequate insurance coverage or other protection.

While Occidental performed due diligence on CrownRock prior to Occidental’s entry into the Purchase Agreement, Occidental is dependent on the accuracy and completeness of statements and disclosures made or actions taken by CrownRock and its representatives when conducting due diligence and evaluating the results of such due diligence. Occidental does not control and may be unaware of activities of CrownRock prior to the completion of the CrownRock Acquisition, including intellectual property and other litigation, claims or disputes, information security vulnerabilities, violations of laws, policies, rules and regulations, commercial disputes, tax liabilities and other known and unknown liabilities.

If the CrownRock Acquisition is consummated, the liabilities of CrownRock, including contingent liabilities, will be consolidated with Occidental’s liabilities for purposes of financial reporting. If CrownRock’s liabilities are greater than expected, or if there are obligations of CrownRock of which Occidental is not aware, Occidental’s business could be materially and adversely affected. While the Cash Purchase Price is subject to a negative adjustment for title and environmental defects identified by Occidental prior to the consummation of the CrownRock Acquisition (subject, in each case, to certain customary exceptions, thresholds and deductibles and offset by any title benefits identified by Occidental), Occidental does not have indemnification rights from the current owners of CrownRock and instead will rely on a limited representation and warranty insurance policy, which Occidental has obtained. Such insurance is subject to exclusions, policy limits and certain other customary terms and conditions. CrownRock may also have other unknown liabilities, which Occidental will be responsible for after consummation of the CrownRock Acquisition. If Occidental is responsible for liabilities not covered by representation and warranty insurance, Occidental could suffer consequences that could have a material adverse effect on its financial condition and results of operations.

Occidental will incur a substantial amount of indebtedness in connection with the financing of the CrownRock Acquisition.

Occidental expects to fund the cash portion of the consideration by incurring up to $9.1 billion of third-party indebtedness. In addition, Occidental expects to assume approximately $1.2 billion of CrownRock’s outstanding long-term debt in the CrownRock Acquisition. Occidental cannot guarantee that it will be able to generate sufficient cash flow to service and repay this indebtedness, or that it will be able to refinance such indebtedness on favorable terms, or at all. The failure to repay or refinance such indebtedness as expected could have a material adverse effect on Occidental’s business, financial condition, results of operation, cash flows and/or stock price. If Occidental is unable to service such indebtedness and fund its operations, Occidental may be forced to reduce or delay capital expenditures, seek additional capital, sell assets or refinance Occidental’s indebtedness. Any such action may not be successful and Occidental may be unable to service such indebtedness and its operations, which could have a material adverse effect on Occidental’s business, financial condition, results of operation, cash flows and/or stock price.

In addition, the terms of such indebtedness may restrict certain actions by Occidental and its subsidiaries. The exact terms of such restrictions, if any, will be subject to negotiations prior to consummation of the applicable financing transaction. Such restrictive covenants may limit the ability of Occidental and its subsidiaries. A breach of any of these restrictive covenants, if applicable, could result in default under the applicable debt instrument. Further, Occidental and its subsidiaries may be prevented from taking advantage of business opportunities that arise because of the limitations imposed on them by any restrictive covenants and financial covenants contained in such debt instruments. The requirement that Occidental and its subsidiaries comply with these provisions may materially adversely affect Occidental’s and its subsidiaries’ ability to react to changes in market conditions, take advantage of business opportunities that Occidental believes to be desirable, obtain future financing, fund needed capital expenditures or withstand a downturn in Occidental’s business.

Occidental may not be able to obtain its preferred form of debt financing in connection with the CrownRock Acquisition on anticipated terms or at all.

Occidental expects to fund a portion of the cash consideration for the CrownRock Acquisition and the payment of fees and expenses related to the CrownRock Acquisition using the proceeds of long-term debt financing, which Occidental expects to include the issuance of debt securities through a public offering or in a private placement, in addition to borrowings under a new term loan facility. There is a risk, however, that market conditions will not be conducive to Occidental executing this financing plan with respect to the long-term financing, or that such long-term financing will not be available on favorable terms, or at all. As a result, Occidental may need to pursue other options, including borrowings under


OXY 2023 FORM 10-K			23


						RISK FACTORS

the bridge facility, which may result in less favorable financing terms that could increase costs and/or adversely impact the operations of Occidental.

Occidental may not be able to complete its planned divestitures of certain assets on favorable terms or at all.

Although Occidental intends to complete $4.5 to $6.0 billion of divestitures of certain assets within 18 months after completion of the CrownRock Acquisition, Occidental may not be able to complete its planned divestitures on favorable terms, in a timely manner or at all. Additionally, the completion of any future divestitures will be subject to customary closing conditions, including, if applicable, the receipt of required government and regulatory approvals. Any difficulties with respect to the completion of the planned divestitures could have a material adverse effect on Occidental’s businesses, financial condition, results of operations, cash flows and/or stock price.

The CrownRock Acquisition is subject to certain government approvals, and if such approvals are not granted or are granted with conditions that become applicable to the parties, completion of the CrownRock Acquisition may be jeopardized or prevented or the anticipated benefits of the transactions could be reduced.

Completion of the CrownRock Acquisition is conditioned upon the expiration or termination of the waiting period relating to the CrownRock Acquisition under the Hart-Scott-Rodino Act, as amended (the HSR Act). On December 20, 2023, each of Occidental and the Sellers filed their respective premerger notification and report in connection with the CrownRock Acquisition with the DOJ and the FTC under the HSR Act. On January 19, 2024, Occidental and CrownRock each received a Second Request for additional information and documentary material from the FTC in connection with the FTC’s review of the CrownRock Acquisition. Issuance of the Second Request extends the waiting period under the HSR Act until 30 days after both Occidental and the Sellers have substantially complied with the Second Request, unless the waiting period is terminated earlier by the FTC or the parties otherwise commit not to close the CrownRock Acquisition for some additional period of time. Occidental and the Sellers are cooperating with the FTC in its review of the CrownRock Acquisition and are working diligently to satisfy the closing condition as soon as possible.

Under the terms of the Purchase Agreement, Occidental and the Sellers have agreed to use reasonable best efforts to obtain the required government approvals and complete the CrownRock Acquisition as promptly as practicable, subject to certain exceptions, including that Occidental will not be required to take or authorize any action that would reasonably be expected to have a material adverse effect on the financial condition, business, assets or results of operations of Occidental, CrownRock and their respective subsidiaries and affiliates (provided that, for purposes of such determination, Occidental, CrownRock and their respective subsidiaries and affiliates, taken as a whole, will be deemed a consolidated group of entities of the size and scale of a hypothetical company that is 100% of the size CrownRock and its subsidiaries as of the date of the Purchase Agreement). The FTC may be affected by government shutdowns, which could result in delays regarding any potential approvals or other actions.

ITEM 1B. UNRESOLVED STAFF COMMENTS

None.

ITEM 1C. CYBERSECURITY

RISK MANAGEMENT AND STRATEGY

Occidental has implemented and maintains processes for assessing, identifying and managing material risks from potential unauthorized occurrences on or through its IT and ICS networks that may result in material adverse effects on the confidentiality, integrity and availability of Occidental’s systems and the information residing in those systems. These include a wide variety of mechanisms, controls, technologies, methods, systems, written policies, physical safeguards and other processes designed to prevent or mitigate data loss, theft, misuse or other security incidents or vulnerabilities affecting Occidental’s systems and the data it collects, processes, stores and transmits as part of its businesses.

Occidental has developed a robust cybersecurity program which is reviewed by senior leadership including its Chief Information Officer (CIO) and other stakeholders as part of its standard general IT controls. Business network and ICS cybersecurity risks are handled by separate and dedicated Occidental teams and are incorporated into Occidental’s enterprise risk management program.

Occidental’s cybersecurity strategy is intended to mitigate cybersecurity threats identified in the risk management process and provide a framework for Occidental to have appropriate administrative, technical and physical safeguards to protect its systems and data and respond effectively to cybersecurity threats. The Company’s cybersecurity program aligns with the NIST framework and leverages people, processes and technology to identify and respond to cybersecurity threats in a timely manner. Occidental relies on continuous security monitoring, penetration testing, vulnerability scanning, personnel training and other tools to identify and mitigate potential cybersecurity threats. Occidental also has established cybersecurity policies that address its cybersecurity practices and controls. The Company conducts internal security audits, including audits conducted by third parties, and other assessments. In addition to its administrative and technical safeguards, Occidental has implemented physical safeguards intended to mitigate risks to its systems. Using a standardized written evaluation and other investigative processes, Occidental identifies and assesses cybersecurity risks flowing from its vendors and suppliers, and manages these using a risk-based approach.


24			OXY 2023 FORM 10-K


						OTHER INFORMATION

Occidental has implemented and maintains a cybersecurity incident response plan that provides the organizational and operational protocol for the Company to effectively and timely respond to cybersecurity incidents. In the event of a material cybersecurity incident, Occidental’s CIO will receive regular updates and monitor detection, mitigation and remediation through reports from a team of experienced cybersecurity leaders responsible for actioning the Company’s cybersecurity incident response plan. As a material cybersecurity incident is handled by the team, the CIO will maintain communication and information flow to senior leadership as well as the Audit Committee and/or the Board, as appropriate.

Cybersecurity risks and associated mitigation strategies and efforts are analyzed by senior leadership as part of the enterprise risk assessments that are reported to and discussed by the Board. Additional information on cybersecurity risks Occidental faces is discussed in Item 1A of Part I, “Risk Factors,” under the heading “Occidental is exposed to cyber-related risks,” which should be read in conjunction with the foregoing information.

Occidental’s business strategy, results of operations and financial condition have not been materially affected by risks from cybersecurity threats, including as a result of previously identified cybersecurity incidents, but Occidental cannot provide assurance that they will not be materially affected in the future by such risks or any future material incidents. For more information on Occidental’s cybersecurity related risks, see Item 1A “Risk Factors” of this Annual Report on Form 10-K.

GOVERNANCE

BOARD

The Audit Committee of the Board oversees the Company’s IT security programs, including cybersecurity, which includes review of possible external threats and potential mitigations. The Board also reviews the Company’s cybersecurity program at least annually. In this review, the CIO briefs the full Board on cybersecurity and data protection matters, including analysis and review of the measures implemented by the Company to identify and mitigate cybersecurity risks. Occidental also has protocols by which material cybersecurity incidents are to be reported to the Audit Committee and/or the Board, as appropriate.

SENIOR MANAGEMENT

Occidental’s CIO, who has over 20 years of IT and cybersecurity experience at the Company and elsewhere, heads the team responsible for implementing and maintaining cybersecurity and data protection practices across Occidental’s businesses and reports directly to the President and CEO. Occidental has a centrally coordinated team, led by its CIO, responsible for implementing and maintaining cybersecurity and data protection practices across the Company. Occidental’s CIO regularly reviews risk management measures and the overall cyber risk strategy implemented and maintained by the Company. The CIO receives regular updates on Occidental’s cybersecurity program and monitors the prevention, detection, mitigation and remediation of cybersecurity incidents through reports from the Company’s cybersecurity leaders, each of whom is supported by a team of trained cybersecurity professionals. In addition to Occidental’s extensive in-house cybersecurity capabilities, Occidental also engages assessors, consultants, auditors or other third parties when necessary to assist with assessing, identifying and managing cybersecurity risks.

ITEM 3. LEGAL PROCEEDINGS

Occidental has elected to use a $1 million threshold for disclosing certain proceedings arising under federal, state or local environmental laws when a government authority is a party and potential monetary sanctions are involved. Occidental believes proceedings under this threshold are not material to Occidental's businesses and financial condition. A subsidiary of Occidental has settled a previously disclosed matter by paying in January 2024 an administrative penalty of $1.2 million to the State of New Mexico to resolve violations alleged to have occurred under federal and state air quality regulations between 2016 and 2019 at a facility in Eddy County, New Mexico, and that were voluntarily disclosed by the subsidiary. For information regarding other legal proceedings, see the information under Lawsuits, Claims, Commitments and Contingencies in the Management’s Discussion and Analysis section of this Form 10-K and in Note 13 - Lawsuits, Claims, Commitments and Contingencies in the Notes to Consolidated Financial Statements in Part II Item 8 of this Form 10-K.

OXY 2023 FORM 10-K			29


						MANAGEMENT’S DISCUSSION AND ANALYSIS


CURRENT BUSINESS OUTLOOK AND STRATEGY

GENERAL

Occidental’s operations, financial condition, cash flows and levels of expenditures are highly dependent on oil prices and, to a lesser extent, NGL and natural gas prices, Midland-to-Gulf-Coast oil spreads, chemical product prices and inflationary pressures in the macro-economic environment. In 2023, as compared to 2022, the average annual price per barrel of WTI crude decreased to $77.64 from $94.23, and the average annual Brent price per barrel decreased to $82.25 from $98.83. The macroeconomic softening of major world economies as inflation pressures are being mitigated with higher interest rates have resulted in a decrease in benchmark oil prices year-over-year. It is expected that the price of oil will be volatile for the foreseeable future given the current geopolitical risks, evolving macro-economic environment that impacts energy demand, future supply actions by OPEC and non-OPEC oil producing countries, the Russia-Ukraine war and conflicts in the Middle East, and the Biden Administration's management of the U.S. Strategic Petroleum Reserve. Occidental does not operate or own assets in Russia or Ukraine, or in the immediate vicinity of ongoing conflicts in the Middle East.

Occidental works to manage inflation impacts by capitalizing on operational efficiencies, locking in pricing on longer term contracts and working closely with vendors to secure the supply of critical materials. As of December 31, 2023, substantially all of Occidental's outstanding debt was fixed rate.

STRATEGY

Occidental is focused on delivering a unique shareholder value proposition with its portfolio of oil and gas, chemicals and midstream and marketing assets and its ongoing development of carbon management and storage solutions and GHG emissions reduction efforts. Occidental conducts its operations with a priority on HSE, sustainability and social responsibility. Occidental aims to maximize shareholder returns through a combination of:

■Delivering a sustainable and growing dividend;

■Enhancing its asset base with new investments in its cash-generative energy and chemical businesses as well as emerging low-carbon businesses;

■Advancing technologies and business solutions to help drive a sustainable low-carbon future;

■Further reducing long-term financial leverage; and

■Strengthening Occidental’s U.S. onshore portfolio with premier Permian Basin assets through the CrownRock Acquisition, which is expected to be immediately cash flow accretive.

OPERATIONAL EXCELLENCE AND CAPITAL EFFICIENCY

Occidental's operational priorities for 2023 were to maximize operational efficiencies by investing $5.0 billion in high return upstream assets to generate long-term free cash flow that will provide cash flow stability throughout the commodity cycle. Occidental set new operational records and efficiency benchmarks in the Permian, Rockies, Gulf of Mexico, Oman and UAE. Despite a softer market, OxyChem generated its third-highest year of earnings. With favorable commodity prices and Occidental’s success with operational efficiencies, Occidental’s generated cash flow enabled share repurchases and the commencement of preferred equity redemption, advancing its shareholder return framework.

DEBT

As of December 31, 2023, future principal payments of debt were less than $18.0 billion, of which $1.1 billion is due in in 2024, $1.2 billion in 2025, $1.4 billion in 2026, $0.9 billion in 2027, and $13.3 billion due in 2028 and thereafter.

In connection with entering into an agreement to acquire CrownRock, Occidental secured a fully-committed $5.3 billion bridge loan facility, a $2.0 billion 364-day term loan, and a $2.7 billion two-year term loan. Prior to or concurrent with the closing of the acquisition, Occidental plans to issue new debt comprised of a combination of the term loans and senior unsecured notes. In addition, Occidental plans to refinance a majority of the $1.2 billion of CrownRock’s existing debt assumed in the acquisition. Occidental intends to repay at least $4.5 billion of debt within twelve months of closing the acquisition with proceeds from the divestiture program and excess cash flows.

DEBT RATINGS

As of the date of this filing, Occidental’s long-term debt was rated Baa3 by Moody’s Investors Service, BBB- by Fitch Ratings and BB+ by Standard and Poor’s. Occidental's credit rating was upgraded to investment grade by Moody's Investors Service in March 2023 and by Fitch Ratings in May 2023. Any downgrade in credit ratings could impact Occidental's ability to access capital markets and increase its cost of capital. A non-investment grade debt rating may require Occidental or its subsidiaries to provide financial assurance in the form of cash, letters of credit, surety bonds or other acceptable support under certain contractual arrangements.


30			OXY 2023 FORM 10-K


						MANAGEMENT’S DISCUSSION AND ANALYSIS

SHAREHOLDER RETURN PRIORITIES

Capital is returned to shareholders through Occidental’s dividend and share repurchases. In 2023, Occidental declared dividends to common shareholders of $646 million, or $0.72 per share, and repurchased 29.1 million common shares at an average price of $61.09 per share under the $3.0 billion share repurchase program announced in February 2023. In February 2024, Occidental’s Board declared an increased dividend rate of $0.22 per share per quarter or $0.88 on an annualized basis. Additional free cash flows from the CrownRock Acquisition are expected to support the increase of the quarterly dividend to $0.22 per share. As of December 31, 2023, $1.2 billion remained of Occidental’s $3.0 billion share repurchase program, which the Board authorized in February 2023.

In 2023, Occidental redeemed preferred stock with a face value of $1.5 billion, and incurred $151 million in redemption premiums as its trailing 12-month distributions to common shareholders were above $4.00 per share. As of December 31, 2023, $8.5 billion face value of the preferred stock remains outstanding. In light of the CrownRock Acquisition, Occidental’s shareholder return priorities aim to provide a growing sustainable dividend and reduce outstanding debt principal to below $15 billion before resuming share repurchases.

SUSTAINABILITY AND ENVIRONMENTAL STEWARDSHIP STRATEGY

In 2020, Occidental was the first U.S. oil and gas company to announce goals to achieve net-zero GHG emissions for its total emissions inventory including use of sold products. These goals include achieving net-zero GHG emissions (i) from its operations and energy use before 2040, with an ambition to do so before 2035, and (ii) from its total carbon inventory, including the use of its sold products, with an ambition to do so before 2050. In 2020, Occidental also set various interim targets, including 2025 carbon and methane intensity targets, and Occidental was the first U.S. oil and gas company to endorse the World Bank’s initiative for zero routine flaring by 2030. In 2022, the Board of Directors adopted Occidental’s updated HSE and Sustainability Principles, based on engagement with shareholders, employees and other stakeholders. The Principles reinforce the alignment among Occidental’s core values, goals and strategies, underpin its Operational Management System, and help to guide the workforce across its businesses.

Occidental seeks to meet its sustainability and environmental goals through its development and commercialization of technologies that lower both GHG emissions from industrial processes and existing atmospheric concentrations of CO2. Occidental believes that carbon removal technologies, including DAC and CCUS, can, with incentives necessary for their development and deployment, provide essential CO2 reductions to assist the world’s transition to a less carbon-intensive economy. As a result of these initiatives, Occidental has completed the following actions, among others, toward advancing its low-carbon strategy:

■Acquired full ownership of DAC technology developer Carbon Engineering, Ltd;

■Reduced estimated methane emissions by approximately 58% from 2019 and 40% from 2021, along with CO2 reductions;

■Entered into a joint venture agreement with BlackRock, through a fund managed by its Diversified Infrastructure business, for the development of STRATOS, Occidental’s first large-scale Direct Air Capture plant in Ector County, Texas, which provides $550 million of committed investment from BlackRock's fund;

■STRATOS construction progressed on schedule;

■South Texas DAC Hub selected for a U.S. Department of Energy DAC demonstration grant, with funding to be announced in 2024, and commenced front-end engineering and design;

■Achieved global 67% reduction in routine flaring of gas in 2023 from its 2020 baseline through commissioning additional compression in Oman while its U.S. oil and gas operations sustained zero routine flaring;

■Removed or converted all remaining high-bleed pneumatic control devices found in Occidental’s U.S. onshore oil and operations; and

■Original signatory to the Oil and Gas Decarbonization Charter and committed funding to the World Bank’s Global Flaring and Methane Reduction Partnership, both announced at the UN’s COP28 Climate Change Conference.

The future costs associated with emissions reduction, carbon removal and CCUS to meet its long-term net-zero GHG goals may be substantial and execution of Occidental’s plans and net-zero pathway depends on securing third-party capital investments. As reflected by the joint venture with BlackRock, Occidental is pursuing multiple pathways to fund these projects including project financing, long-term carbon removal or CCUS agreements, and identifying business opportunities with stakeholders in carbon-intensive industries.

						MANAGEMENT’S DISCUSSION AND ANALYSIS

KEY PERFORMANCE INDICATORS

Occidental seeks to meet its strategic goals by continually measuring its success against key performance indicators that drive total stockholder return. In addition to efficient capital allocation and deployment discussed below in the section titled Oil and Gas Segment - Business Strategy, Occidental believes its most significant performance indicators are:

OPERATIONAL

■Total spend per barrel - In 2024, Occidental will continue to focus on controlling total costs from a per-barrel perspective. Total spend per barrel is the sum of capital spending, general and administrative expenses, other operating and non-operating expenses and oil and gas lease operating costs divided by global oil, NGL and natural gas sales volumes.

■Daily production - Occidental seeks to maximize field operability and minimize production down-time.

FINANCIAL

■CROCE - CROCE is calculated as (i) the cash flows from operating activities, before changes in working capital, plus distributions from WES classified as investing cash flows, divided by (ii) the average of the opening and closing balances of total equity plus total debt.

■Credit rating - Maintain and improve financial leverage to a level consistent with investment grade credit metrics.

SUSTAINABILITY AND ENVIRONMENTAL

■Specific interim emissions reduction and emissions intensity targets to advance the goal of net-zero operational and energy use emissions before 2040, with an ambition to achieve before 2035.

■Milestones in specific carbon removal and CCUS projects that advance a net-zero total emissions inventory, including use of sold products, with an ambition to achieve before 2050.

■Facilitate deployment of carbon removal, CCUS and other solutions to advance total carbon impact past 2050.

OIL AND GAS SEGMENT

BUSINESS STRATEGY

Occidental’s oil and gas segment focuses on long-term value creation and leadership in sustainability, health, safety and the environment. In each core operating area, Occidental’s operations benefit from scale, technical expertise, decades of high-margin inventory, environmental and safety leadership and commercial and governmental collaboration. These attributes allow Occidental to bring additional production quickly to market, extend the life of older fields at lower costs and provide low-cost returns-driven growth opportunities with advanced technology.

Occidental is one of the largest U.S. producers of liquids, which includes oil and NGL, allowing Occidental to maximize cash margins on a per barrel basis. The advantages that Occidental’s portfolio provides, coupled with its advanced subsurface characterization ability and the proven ability to execute, position Occidental for full-cycle success in the years ahead. The oil and gas segment maximizes efficiencies to deliver lower breakeven costs and generate excess free cash flow. The oil and gas segment strives to achieve low development and operating costs to maximize full-cycle value of the assets.

The oil and gas business implements Occidental’s strategy primarily by:

■Operating and developing areas where reserves are known to exist and optimizing capital intensity in core areas, primarily in the Permian Basin, DJ Basin, Gulf of Mexico, UAE, Oman and Algeria;

■Maintaining a disciplined and prudent approach to capital expenditures with a focus on high-return, short and mid-cycle, cash-flow-generating opportunities and an emphasis on creating value and further enhancing Occidental’s existing positions;

■Focusing Occidental’s subsurface characterization and technical activities on both conventional and unconventional resources in the Permian Basin, Rockies, Gulf of Mexico and International;

■Using secondary and tertiary recovery techniques in mature fields; and

■Focusing on cost-reduction efficiencies and innovative technologies to reduce carbon emissions.

In 2023, oil and gas capital expenditures were approximately $5.0 billion and primarily focused on Occidental’s assets in the Permian Basin, DJ Basin, Gulf of Mexico and Oman. In 2024, Occidental plans to spend $4.8 billion to $5.0 billion to develop its oil and gas assets, excluding amounts associated with the CrownRock Acquisition.


32			OXY 2023 FORM 10-K


						MANAGEMENT’S DISCUSSION AND ANALYSIS

In December 2023, Occidental entered into an agreement to purchase CrownRock L.P. for total consideration of $12.0 billion. Occidental intends to finance the purchase with the issuance of $9.1 billion of new debt, the issuance of approximately $1.7 billion of common equity and the assumption of CrownRock’s $1.2 billion of existing debt. Occidental believes the CrownRock Acquisition will deliver immediate and significant free cash flow accretion and improve scale in the Midland Basin, along with a unique opportunity to add to Occidental’s high-grade U.S. onshore asset portfolio. This free cash flow accretion will also enable Occidental to increase its dividend in the near term, and provides high-margin inventory that will support the sustainable growth over time.

On January 19, 2024, Occidental and the Sellers each received a Second Request from the FTC in connection with the FTC’s review of the CrownRock Acquisition. A Second Request extends the waiting period imposed by the HSR Act until 30 days after each of Occidental and the Sellers have substantially complied with the Second Request issued to them, unless that period is extended voluntarily by Occidental and the Sellers or terminated sooner by the FTC. Occidental and the Sellers continue to work constructively with the FTC in its review of the CrownRock Acquisition, which Occidental expects will close in the second half of 2024.

OIL AND GAS PRICE ENVIRONMENT

Oil and gas prices are the major variables that drive the industry’s financial performance. The following table presents the average daily WTI and Brent prices for oil and NYMEX natural gas prices for 2023 and 2022:


	2023		2022		% Change
WTI Oil ($/Bbl)	$	77.64	$	94.23	(18)	%
Brent Oil ($/Bbl)	$	82.25	$	98.83	(17)	%
NYMEX Natural Gas ($/Mcf)	$	2.94	$	6.35	(54)	%

The following table presents Occidental’s average realized prices for continuing operations as a percentage of WTI, Brent and NYMEX for 2023 and 2022:


	2023		2022
Worldwide oil as a percentage of average WTI	99	%	100	%
Worldwide oil as a percentage of average Brent	93	%	95	%
Worldwide NGL as a percentage of average WTI	27	%	38	%
Worldwide NGL as a percentage of average Brent	26	%	36	%
Domestic natural gas as a percentage of NYMEX	69	%	86	%

Prices and differentials can vary significantly, even on a short-term basis, making it difficult to predict realized prices with a reliable degree of certainty.

DOMESTIC INTERESTS

BUSINESS REVIEW

Occidental conducts its domestic operations through land leases, subsurface mineral rights it owns, or a combination of both. Occidental’s domestic oil and gas leases have a primary term ranging from one to 10 years, which is extended through the end of production once it commences. Occidental has leasehold and mineral interests in 9.3 million net acres, of which approximately 51% is leased, 48% is owned subsurface mineral rights and 1% is owned land with mineral rights. Approximately $4.1 billion to $4.3 billion of Occidental’s worldwide capital budget is expected to be allocated to its domestic operations in 2024, before the impact of the CrownRock Acquisition.

(a)Map represents geographic outlines of the respective basins.

The Permian Basin

The Permian Basin extends throughout West Texas and Southeast New Mexico and is one of the largest and most active oil basins in the United States, accounting for more than 45% of total United States oil production in 2023. Overall in 2023, Occidental’s production in the Permian Basin was approximately 584 Mboe/d.

Occidental manages its Permian Basin operations through two businesses: Permian Resources, which includes unconventional opportunities, and Permian EOR, which utilizes secondary and tertiary recovery techniques. Occidental had a leading position in the Permian Basin, producing approximately 9% of the total oil in the basin in 2023. By exploiting the natural synergies between Permian Resources and Permian EOR, Occidental is able to deliver unique short- and long-term advantages, efficiencies and expertise across its Permian Basin operations.

The Permian Resources unconventional business is focused on developing and producing unconventional reservoir targets using horizontal drilling technology. The development programs are designed to create long-term value from primary development by maximizing the recovery of oil, utilizing sustainable practices and providing strong financial returns. Occidental’s unconventional oil and gas operations in Permian Resources include approximately 1.4 million net acres. In 2023, Occidental’s activities were focused in the core development areas with emphasis on maintaining the industry leading capital intensity through optimized surface infrastructure and customized well designs. Overall, in 2023, Permian Resources produced from approximately 4,520 gross wells and added 265 MMboe to Occidental’s proved reserves through infill development projects and extensions of proved areas.

The Permian Basin’s concentration of large conventional reservoirs, strong CO2 flooding performance and the expansive CO2 transportation and processing infrastructure has resulted in decades of high-value enhanced oil production. With 34 active CO2 floods and over 50 years of experience, Occidental is the industry leader in Permian Basin CO2 flooding, which can increase ultimate oil recovery by 10% to 25%. Technology improvements, such as the recent trend toward vertical expansion of the CO2 flooded interval into residual oil zone targets, continue to yield more recovery from existing projects. Significant opportunities also remain to gain additional recovery by expanding Occidental’s existing CO2 projects into new portions of reservoirs that have only been waterflooded. Permian EOR has 1.4 million net acres with a large inventory of future CO2 projects, which could be developed over the next 20 years or accelerated, depending on market conditions. Permian EOR produced from approximately 13,000 gross wells in 2023. In 2023, Occidental spent approximately $2.8 billion of capital in the Permian Basin, of which 88% was spent on Permian Resources assets.

						MANAGEMENT’S DISCUSSION AND ANALYSIS

Rockies and Other Domestic

In 2023, Occidental produced approximately 271 Mboe/d net and spent capital of approximately $0.7 billion in the Rockies and Other Domestic locations. Production in the DJ Basin is derived from approximately 4,050 wells primarily focused in the Niobrara and Codell formations. The DJ Basin, including the North DJ Basin, comprises approximately 0.7 million total net acres and provides competitive economics, low breakeven costs and free cash flow generation through Occidental’s contiguous acreage position and royalty uplift.

Operations in the DJ Basin are subject to regulations that impose siting requirements, or “setback,” on certain oil and gas drilling locations based on the distance of a proposed well pad to occupied structures. Occidental has dedicated stakeholder relations team that conducts regulatory and community outreach with respect to its permit applications and operations in Colorado with a focus on building trust and fostering open communication with those that live and work near its operations. Through thoughtful planning, Occidental has established a steady cadence of permit approvals through various agencies, local governments and the ECMC through the demonstration of best-in-class operations mitigations, robust community outreach and protective site selection. In 2023, Occidental submitted Oil and Gas Development Plans comprising over 200 wells to the ECMC. Additionally, during the third quarter of 2022, Occidental became the first oil and gas operator in Colorado to obtain ECMC approval for the first Comprehensive Area Plan under the new ECMC rules. This comprehensive plan will support nine well pads (approximately 140 new wells) and will provide for substantial future development in a geographically remote are on Colorado’s eastern plains. It is anticipated that the first Oil and Gas Development Plan associated with the comprehensive plan will be heard by the ECMC Professional Commission during the first quarter of 2024. As of December 31, 2023, Occidental was permitted, or had submitted permit applications to applicable regulatory agencies, for nearly all planned 2024 drilling and completions activity in the DJ Basin. Occidental continues to gain efficiencies in the permitting process and will continue to look for additional opportunities to do so in the year ahead.

Occidental has interest in over 0.3 million net acres in the Powder River Basin, mainly located in Converse County and Campbell County, Wyoming. The field contains the Turner, Niobrara, Mowry and Parkman formations that hold both liquids and natural gas.

Occidental holds approximately 4.6 million net acres in other domestic locations, which consist of acreage and fee minerals outside of Occidental’s core operated areas including parts of Arkansas, Colorado, Louisiana, Texas, West Virginia and Wyoming.

OFFSHORE DOMESTIC ASSETS

Gulf of Mexico

Occidental is the fourth-largest oil and gas producer in the deep-water Gulf of Mexico, operating 10 strategically located deep-water floating platforms, the highest number among all the deep water operators, and producing from 18 active fields while owning a working interest across 261 blocks, including approximately 0.9 million net acres.

Occidental further operates two marine shore-bases in Galveston, Texas, and Port Fourchon, Louisiana, as well as two helicopter bases in Louisiana, providing back-up and redundancy to support its Gulf operations. A central logistics base and an integrated training center is located in Broussard, Louisiana, and Gulf of Mexico operations and development are managed and supported with engineering and technical staff located in The Woodlands, Texas.

Development projects continued with the strategy of accelerated delivery at Horn Mountain, Lucius, and Holstein facilities. Drilling and well services also ramped up activities, using one floating drill ship, one platform rig and several service rigs, with a second drillship being contracted in the last two months of the year, initially for well workovers. The Marco Polo K2 Subsea Pumping project was successfully started up four months ahead of schedule, enabling increased production and future well development. In 2023, Occidental spent $400 million of capital on development projects.

OBN seismic projects were further expanded in 2023, including at the K2 field, setting up a runway of future development opportunities. Asset development switched to a focus of assessing growth potential from all of its current inventory using secondary recovery techniques and expects to propose new development opportunities beginning around 2025.

In 2023, Occidental increased net production to 145 Mboe/d from 85 gross wells. Occidental focused base production management and artificial lift projects, which successfully reduced reservoir declines. Operational excellence and efficiency continued as a core objective in 2023. Occidental’s Gulf of Mexico Production Operations and Asset Integrity teams continued achieving world class platform operating efficiencies and major equipment uptime in 2023, with major platform and equipment uptimes increasing from 90% to 98%. Multiple platform seasonal shut-ins were planned and executed safely and efficiently in 2023 delivering a 40% reduction in numbers of shut-in days as compared to 2019 and steering on course to implement planned shut-ins only once each two years for each facility. In the fourth quarter of 2023, at the request of the Main Pass Oil Gathering system operator, Occidental temporarily halted certain operations in the eastern Gulf of Mexico. These operations are expected to be restarted in early 2024.

During 2023, all necessary regulatory permits for new wells and existing operations were obtained timely without any operational delays. Occidental was further awarded 11 new leases from BOEM’s Lease Sale 259. Occidental participated in Lease Sale 261, held on December 20, 2023 and was the apparent high bidder on 49 of 57 total blocks.

Occidental’s Gulf of Mexico assets continued to be among the lowest carbon emissions operations in the industry with zero routine flaring and zero cold venting. Occidental’s Gulf of Mexico operations were also recognized by the Center of Offshore Safety for its industry award winning 2023 Heat Stress Program and its continued dedication to improving HSE.

In 2024, Occidental expects to commence new expansions using advanced recovery techniques as well as continuing development of its existing assets across the Gulf of Mexico that deliver some of the highest margin production in its portfolio. Occidental plans to conduct development and exploration activities in 2024 using two floating drill ships and several other well service vessels and continue to optimize its extensive portfolio of lease working interests.

INTERNATIONAL INTERESTS

BUSINESS REVIEW

Occidental conducts its ongoing international operations in two sub-regions: the Middle East and North Africa. Its activities include oil, NGL and natural gas production through direct working-interests, PSAs and PSCs. Under the PSCs, Occidental records a share of production and reserves to recover certain development and production costs and an additional share for profit. These contracts do not transfer any right of ownership to Occidental and reserves reported from these arrangements are based on Occidental’s economic interest as defined in the contracts. Occidental’s share of production and reserves from these contracts decreases when product prices rise and increases when prices decline. Overall, Occidental’s net economic benefit from these contracts is greater when product prices are higher. Approximately $0.5 billion of Occidental’s worldwide capital budget is expected to be allocated to its international operations in 2024.

						MANAGEMENT’S DISCUSSION AND ANALYSIS

Algeria

Occidental’s interest in Algeria involves development and production rights in 18 fields within Blocks 404a and 208, which are located in the Berkine Basin in Algeria’s Sahara Desert and are governed by an agreement amongst Occidental, Sonatrach and other partners. Occidental is responsible for 35% of the development and production costs. The El Merk central processing facility in Block 208 processes produced oil, NGL and natural gas, while the Hassi Berkine South and Ourhoud central processing facilities in Block 404a process produced oil. The rights to produce from the Block 404a and Block 208 fields under the new development agreement commenced May 3, 2023 and will continue until 2048.

In 2023, net production in Algeria was 32 Mboe/d, two gross development wells were drilled and annual net capital expenditures were $30 million.

Oman

In Oman, Occidental is the operator of Block 9, Block 27, Block 53 (Mukhaizna Field), Block 62 and Block 65 and has additional interests in Blocks 30, 51 and 72, which are under the Exploration phase. The working interest and contract expiration year for each of the respective blocks are shown in the table below. Occidental holds 6.0 million gross acres and has 10,000 potential well inventory locations. In 2023, Occidental’s share of production was 66 Mboe/d.


	Working Interest		Block Expiration (Year)
Block 9	50	%	2030
Block 27	65	%	2035
Block 53	47	%	2035
Block 62	100	%	2028
Block 65	51	%	2037
Blocks 30, 51 and 72	100	%	Exploration Phase

Occidental has produced over 789 million gross barrels from Block 9 since the beginning of its operation through successful exploration, continuous drilling improvements and EOR projects. The Mukhaizna Field in Block 53 is a major pattern steam flood project for EOR that utilizes some of the largest mechanical vapor compressors ever built. Since assuming operations in the Mukhaizna Field in 2005, Occidental has drilled close to 3,600 new wells and has produced over 607 million gross barrels. In 2023, Occidental invested capital of $374 million across all of the Oman blocks to drill 97 wells and execute facilities projects to support development and EOR activities.

In 2024, Occidental will continue to enhance production by adding extended and dual laterals, stimulating wells with the OXY JETTINGTM wellbore stimulation system, and expanding thermal conformance. Occidental will also continue to execute projects in Oman targeting emissions reductions.

Qatar

In Qatar, Occidental partners in the Dolphin Energy Project, an investment that is comprised of two separate economic interests. Occidental has a 24.5% interest in the upstream operations to develop and produce NGL, natural gas and condensate from Qatar’s North Field through mid-2032. Occidental also has a 24.5% interest in DEL, which operates a pipeline and is discussed further in the midstream and marketing segment section in this Form 10-K under Pipeline. In 2023, Occidental’s net share of production from Dolphin was 39 Mboe/d.

UAE

Occidental has a 40% participating interest in the Shah gas field (Al Hosn Gas), joining with the Abu Dhabi National Oil Company, which expires in 2041. In 2023, Occidental’s net share of production from Al Hosn Gas was 267 MMcf/d of natural gas and 38 Mbbl/d of NGL and condensate. Al Hosn Gas includes gas processing facilities which are discussed further in the midstream and marketing segment section in this Form 10-K under Gas Processing, Gathering and CO2. In 2023, Occidental completed an expansion project that commenced in 2022 to increase the production capacity of the Al Hosn Gas processing facilities from 1.28 Bcf/d to 1.45 Bcf/d.

In 2019 and 2020, Occidental acquired 9-year exploration concessions and, subject to a declaration of commerciality, 35-year production concessions for Onshore Block 3 and Block 5, which cover an area approximately 1.5 million acres and 1.0 million acres, respectively, and are adjacent to Al Hosn Gas. In 2023, Occidental commenced first oil production in Onshore Block 3. In 2024, Occidental will continue further exploration and appraisal activities in Onshore Block 3 and Block 5.

						MANAGEMENT’S DISCUSSION AND ANALYSIS

natural gas prices used for this purpose were based on posted benchmark prices and adjusted for price differentials including gravity, quality and transportation costs.

The following table shows the 2023, 2022 and 2021 calculated first-day-of-the-month average prices for both WTI and Brent oil prices, as well as the Henry Hub gas prices:


	2023		2022		2021
WTI Oil ($/Bbl)	$	78.22	$	93.67	$	66.56
Brent Oil ($/Bbl)	$	82.80	$	97.77	$	69.24
Henry Hub Natural Gas ($/MMbtu)	$	2.64	$	6.36	$	3.60
Mt. Belvieu NGL ($/Bbl)	$	29.94	$	47.81	$	44.22

Occidental had proved reserves from continuing operations at year-end 2023 of 3,982 MMboe, compared to the year-end 2022 amount of 3,817 MMboe. Proved developed reserves represented approximately 69% and 71% of Occidental’s total proved reserves at year-end 2023 and 2022, respectively. The following table shows the breakout of Occidental’s proved reserves from continuing operations by commodity as a percentage of total proved reserves:


	2023		2022
Oil	49	%	50	%
NGL	24	%	22	%
Natural gas	27	%	28	%

Occidental does not have any reserves from non-traditional sources. For further information regarding Occidental’s proved reserves, see the Supplemental Oil and Gas Information section in Item 8 of this Form 10-K.

CHANGES IN PROVED RESERVES

Changes in Occidental’s 2023 reserves were as follows:


MMboe						2023
Revisions of previous estimates						406
Improved recovery						23
Extensions and discoveries						153
Purchases						31
Sales						(2)
Production						(446)
Total						165

Occidental’s ability to add reserves, other than through purchases, depends on the success of infill development, extension, discovery and improved recovery projects, each of which depends on reservoir characteristics, technology improvements and oil and natural gas prices, as well as capital and operating costs. Many of these factors are outside management’s control and may negatively or positively affect Occidental’s reserves.

Revisions of Previous Estimates

Revisions can include upward or downward changes to previous proved reserve estimates for existing fields due to the evaluation or interpretation of geologic, production decline or operating performance data. In addition, product price changes affect proved reserves recorded by Occidental. For example, lower prices may decrease the economically recoverable reserves, particularly for domestic properties, because the reduced margin limits the expected life of the operations. Offsetting this effect, lower prices increase Occidental’s share of proved reserves under PSCs because more oil is required to recover costs. Conversely, when prices rise, Occidental’s share of proved reserves decreases for PSCs and economically recoverable reserves may increase for other operations. Reserve estimation rules require that estimated ultimate recoveries be much more likely to increase or remain constant than to decrease, as changes are made due to increased availability of technical data.

In 2023, Occidental’s revisions of previous estimates of proved reserves were positive 406 MMboe. These revisions were primarily due to 303 MMboe of positive revisions related to additions associated with infill development projects, mainly in the DJ Basin (138 MMboe), the Permian Basin (132 MMboe) and Algeria (26 MMboe). Further positive revisions of 192 MMboe were primarily associated with updates based on operating cost models (120 MMboe), reservoir performance (47


38			OXY 2023 FORM 10-K


						MANAGEMENT’S DISCUSSION AND ANALYSIS

MMboe), and the Algeria contract extension (44 MMboe). The positive revisions were partially offset by negative revisions associated with management changes in development plans and interest related revisions (16 MMboe).

This was partially offset by 89 MMboe of negative price revisions. The negative price revisions were primarily associated with the Permian Basin (91 MMboe) and the DJ Basin (5 MMboe), which were partially offset by positive price revisions of 13 MMboe on international PSCs.

Improved Recovery

In 2023, Occidental added proved reserves of 23 MMboe related to improved recovery in Oman (14 MMboe) and Permian EOR (9 MMboe). These properties comprise conventional projects, which are characterized by the deployment of EOR development methods, largely employing application of CO2 flood, waterflood or steam flood. These types of conventional EOR development methods can be applied through existing wells, though additional drilling is frequently required to fully optimize the development configuration. Waterflooding is the technique of injecting water into the formation to displace the oil to the offsetting oil production wells. The use of either CO2 or steam flooding depends on the geology of the formation, the evaluation of engineering data, availability and cost of either CO2 or steam and other economic factors. Both techniques work similarly to lower viscosity causing the oil to move more easily to the producing wells.

Extensions and Discoveries

Occidental also added proved reserves from extensions and discoveries, which are dependent on successful exploration and exploitation programs. In 2023, extensions and discoveries added 153 MMboe primarily related to the recognition of proved reserves in the Permian Basin (133 MMboe) and Gulf of Mexico (11 MMboe).

Purchases of Proved Reserves

In 2023, Occidental purchased proved reserves of 31 MMboe primarily consisting of proved reserves in the DJ Basin.

Sales of Proved Reserves

In 2023, Occidental sold 2 MMboe in proved reserves related to the divestitures of certain non-strategic assets in the Permian Basin.

Proved Undeveloped Reserves

Occidental had PUD reserves at year-end 2023 of 1,232 MMboe, compared to the year-end 2022 amount of 1,119 MMboe.

Changes in PUD reserves were as follows:


MMboe						2023
Revisions of previous estimates						242
Improved recovery						8
Extensions and discoveries						96
Purchases						25
Sales						—
Transfer to proved developed reserves						(258)
Total						113

Revisions of previous estimates were a positive 242 MMboe. Approximately 275 MMboe of the positive revisions were related to additions associated with infill development projects located primarily in the DJ Basin (125 MMboe), the Permian Basin (119 MMboe) and Algeria (25 MMboe). The positive revisions were partially offset by negative other revisions associated primarily with management changes in development plans and the Algeria contract extension (19 MMboe). Additionally, the revisions included negative price revisions of 14 MMboe. The negative price revisions were primarily associated with the Permian Basin.

Extensions and discoveries added 96 MMboe primarily related to the recognition of proved reserves in the Permian Basin (80 MMboe) and Gulf of Mexico (10 MMboe). Total improved recovery additions of 8 MMboe were the result of implementing secondary and tertiary projects in international assets. The 2023 additions to PUD reserves were partially offset by transfers to proved developed reserves of 258 MMboe. The transfers were primarily associated with the Permian Basin (151 MMboe), the DJ Basin (62 MMboe) and UAE (29 MMboe).

In 2023, Occidental incurred approximately $1.6 billion to convert PUD reserves to proved developed reserves, and in 2023 Occidental converted approximately 23% of its PUD reserves to proved developed, when adjusted for revisions and sales. As of December 31, 2023, Occidental had 1,232 MMboe of PUD reserves of which 75% were associated with domestic onshore, 5% with Gulf of Mexico and 20% with international assets. Occidental’s most active development areas are located in the Permian Basin, which represented 50% of the PUD reserves as of December 31, 2023. Occidental’s total


OXY 2023 FORM 10-K			39


						MANAGEMENT’S DISCUSSION AND ANALYSIS

planned 2024 capital expenditures for oil and gas are between $4.8 billion and $5.0 billion. Overall, Occidental plans to spend approximately $5.5 billion over the next five years to develop its PUD reserves in the Permian Basin.

PUD reserves are supported by a five-year detailed field-level development plan, which includes the timing, location and capital commitment of the wells to be drilled. Only PUD reserves which are reasonably certain to be drilled within five years of booking and are supported by a final investment decision to drill them are included in the development plan. A portion of the PUD reserves are expected to be developed beyond the five years and are tied to approved long-term development projects.

As of December 31, 2023, Occidental had 212 MMboe of pre-2019 PUD reserves that remained undeveloped. These PUD reserves relate to approved long-term development plans, 165 MMboe of which are primarily associated with international development projects with physical limitations in existing gas processing capacity and 47 MMboe of which are related to approved long-term development plans for Permian EOR projects, also with physical limitations in existing gas processing capacity. Occidental remains committed to these projects and continues to actively progress the development of these volumes. In addition to the above, Occidental has 29 MMboe of PUD reserves that are scheduled to be developed more than five years from their initial date of booking. These PUD reserves are related to approved long-term development plans, 18 MMboe of which are associated with international development projects and 11 MMboe with the Gulf of Mexico projects.

RESERVES EVALUATION AND REVIEW PROCESS

Occidental’s estimates of proved reserves and associated future net cash flows as of December 31, 2023, were made by Occidental’s technical personnel and are the responsibility of management. The estimation of proved reserves is based on the requirement of reasonable certainty of economic producibility and funding commitments by Occidental to develop the reserves. This process involves reservoir engineers, geoscientists, planning engineers and financial analysts. As part of the proved reserves estimation process, all reserve volumes are estimated by a forecast of production rates, operating costs and capital expenditures. Price differentials between benchmark prices (the unweighted arithmetic average of the first-day-of-the-month price for each month within the year) and realized prices and specifics of each operating agreement are then used to estimate the net reserves. Production rate forecasts are derived by a number of methods, including estimates from decline curve analysis, type well profile analysis, computer simulation of the reservoir performance, volumetric analysis and material balance calculations that take into account the volumes of substances replacing the volumes produced and associated reservoir pressure changes supported by various technologies including seismic analysis. These reliable field-tested technologies have demonstrated reasonably certain results with consistency and repeatability in the formation being evaluated or in an analogous formation. Operating and capital costs are forecast using the current cost environment applied to expectations of future operating and development activities.

Net proved developed reserves are those volumes that are expected to be recovered through existing wells with existing equipment and operating methods for which the incremental cost of any additional required investment is relatively minor.

Net PUD reserves are those volumes that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion. PUD reserves are supported by a five-year, detailed, field-level development plan, which includes the timing, location and capital commitment of the wells to be drilled. The development plan is reviewed and approved annually by senior management and technical personnel. Annually, a detailed review is performed by Occidental’s Corporate Reserves Group and its technical personnel on a lease-by-lease basis to assess whether PUD reserves are being converted on a timely basis within five years from the initial disclosure date. Any leases not showing timely transfers from PUD reserves to proved developed reserves are reviewed by senior management to determine if the remaining reserves will be developed in a timely manner and have sufficient capital committed in the development plan. Only PUD reserves that are reasonably certain to be drilled within five years of booking and are supported by a final investment decision to drill them are included in the development plan. A portion of the PUD reserves associated with international operations are expected to be developed beyond the five years and are tied to approved long-term development plans.

The current Senior Vice President, Reserves for Oxy Oil and Gas is responsible for overseeing the preparation of reserve estimates, in compliance with SEC rules and regulations, including the internal audit and review of Occidental’s oil and gas reserves data. He has over 40 years of experience in the upstream sector of the exploration and production business and has held various assignments in North America, Asia and Europe. He is a three-time past Chair of the Society of Petroleum Engineers Oil and Gas Reserves Committee. He is an AAPG Certified Petroleum Geologist and currently serves on the AAPG Committee on Resource Evaluation. He is a member of the Society of Petroleum Evaluation Engineers, the Colorado School of Mines Potential Gas Committee and the United Nations Economic Commission for Europe Expert Group on Resource Management. He has Bachelor of Science and Master of Science degrees in geology from Emory University in Atlanta.

Occidental has a Reserves Committee, consisting of senior corporate officers, to review and approve Occidental’s oil and gas reserves. The Reserves Committee reports to the Audit Committee of Occidental’s Board of Directors during the year. Since 2003, Occidental has retained Ryder Scott, independent petroleum engineering consultants, to review its annual oil and gas reserve estimation processes. For additional reserves information, see Supplemental Oil and Gas Information under Item 8 of this Form 10-K.


40			OXY 2023 FORM 10-K


						MANAGEMENT’S DISCUSSION AND ANALYSIS

In 2023, Ryder Scott conducted a process review of the methods and analytical procedures utilized by Occidental’s engineering and geological staff for estimating the proved reserves volumes, preparing the economic evaluations and determining the reserves classifications as of December 31, 2023, in accordance with SEC regulatory standards. Ryder Scott reviewed the specific application of such methods and procedures for selected oil and gas properties considered to be a valid representation of Occidental’s 2023 year-end total proved reserves portfolio. In 2023, Ryder Scott reviewed approximately 44% of Occidental’s proved oil and gas reserves. Since being engaged in 2003, Ryder Scott has reviewed the specific application of Occidental’s reserve estimation methods and procedures for approximately 97% of Occidental’s existing proved oil and gas reserves.

Management retained Ryder Scott to provide objective third-party input on its methods and procedures and to gather industry information applicable to Occidental’s reserve estimation and reporting process. Ryder Scott has not been engaged to render an opinion as to the reasonableness of reserves quantities reported by Occidental. Occidental has filed Ryder Scott’s independent report as an exhibit to this Form 10-K.

Based on its reviews, including the data, technical processes and interpretations presented by Occidental, Ryder Scott has concluded that the overall procedures and methodologies Occidental utilized in estimating the proved reserves volumes, preparing the economic evaluations and determining the reserves classifications for the reviewed properties are appropriate for the purpose thereof and comply with current SEC regulations.

OUTLOOK

The oil and gas exploration and production industry is highly competitive, is subject to significant volatility due to various market conditions and operations are highly dependent on oil prices and, to a lesser extent, NGL and natural gas prices. Oil prices decreased in 2023. In 2023, as compared to 2022, the average annual price per barrel of WTI crude decreased to $77.64 from $94.23, the average annual Brent price per barrel decreased to $82.25 from $98.83 and the average annual NYMEX natural gas price per mmcf decreased to $2.94 from $6.35.

Oil prices will continue to be affected by: (i) global supply and demand, which are generally a function of global economic conditions, inventory levels, production or supply chain disruptions, technological advances, regional market conditions and the actions of OPEC, other significant producers and governments; (ii) transportation capacity, infrastructure constraints, and costs in producing areas; (iii) currency exchange rates and inflation rates; and (iv) the effect of changes in these variables on market perceptions. It is expected that the price of oil will be volatile for the foreseeable future given the current geopolitical risks, the ongoing global impact of the Russia-Ukraine war and conflicts in the Middle East, the evolving macro-economic environment and supply activity from OPEC and non-OPEC oil producing countries and the Biden Administration’s releases from the U.S, Strategic Petroleum Reserve. Occidental does not operate or own assets in either Russia or Ukraine, or in the immediate vicinity of ongoing conflicts in the Middle East.

NGL prices are related to the supply and demand for the components of products making up these liquids. Some of them more typically correlate to the price of oil while others are affected by natural gas prices as well as the demand for certain chemical products for which they are used as feedstock. In addition, infrastructure constraints magnify the pricing volatility from region to region.

Domestic natural gas prices and local differentials are strongly affected by local supply and demand fundamentals, as well as government regulations, global LNG demand and availability of transportation capacity from producing areas.

These and other factors make it difficult to predict the future direction of oil, NGL and domestic gas prices reliably. For purposes of the current capital plan, Occidental will continue to focus on allocating capital to high return assets with the flexibility to adjust based on fluctuations in commodity prices. International gas prices are generally fixed under long-term contracts. Occidental continues to adjust capital expenditures in line with current economic conditions, such as supply chain constraints, rising interest rates, global logistics and high inflation, which has continued to disrupt global supply and demand balances, with the goal of keeping returns well above its cost of capital.

The timing, process and ultimate cost to transition to a less carbon-intensive economy remains largely unknown; various industry forecasts indicate a growing demand for hydrocarbons for the remainder of the current decade. Occidental believes its operational flexibility to achieve low development and operating costs to maximize full-cycle value of its assets and its knowledge and experience in CO2 separation, transportation, use, recycling and storage position its oil and gas segment to support Occidental’s transition to net zero as well as create opportunities in a low-carbon future.

						MANAGEMENT’S DISCUSSION AND ANALYSIS


CHEMICAL SEGMENT

BUSINESS STRATEGY

OxyChem concentrates on the chlorovinyls chain, beginning with the co-production of caustic soda and chlorine. Caustic soda and chlorine are marketed to external customers. In addition, chlorine, together with ethylene, is converted through a series of intermediate products into PVC. OxyChem seeks to be a low-cost producer in order to generate cash flow in excess of its normal capital expenditure requirements and achieve above-cost-of-capital returns. OxyChem’s focus on chlorovinyls allows it to maximize the benefits of integration and take advantage of economies of scale. Capital is employed to sustain production capacity and to focus on projects and developments designed to improve the competitiveness of segment assets. Acquisitions and plant development opportunities may be pursued when they are expected to enhance the existing core chlor-alkali and PVC businesses or take advantage of other specific opportunities. The expansion and conversion of the Battleground chlor-alkali plant to membrane technology commenced in 2023 with completion expected in 2026. In 2023, capital expenditures for OxyChem totaled $535 million.

BUSINESS ENVIRONMENT

Although the United States economic growth was slightly higher than that of 2022, demand for domestically produced products decreased, including liquid caustic soda and PVC. High global inflationary pressures resulted in slowing demand for many products, as ethylene and energy costs remained advantaged over global pricing. Caustic soda prices were lower in 2023 and PVC pricing decreased slightly in 2023 after moving downward significantly during the second half of 2022, as supply chain constraints, high interest rates, global logistics and high inflation continued to disrupt global supply and demand balances.

BUSINESS REVIEW

BASIC CHEMICALS

Chlor-alkali operating rates decreased in 2023 as global demand weakened in the face of inflationary pressures. As a result of weakening demand in most segments, pricing and margins declined across the year, and most notably on alkali products.

VINYLS

Domestic PVC demand softened for a second consecutive year in 2023, resulting in a 13% year over year decrease in demand. To offset domestic losses and maintain utilization rates, USGC export volume increased by 30% compared to 2022. Year over year industry operating rates were down 1% in 2023 due to weak global market conditions. High interest rates, slowing housing starts, and inflation continue to keep a ceiling on domestic PVC demand. PVC exports represented 36% of total North American sales in 2023 compared to 27% in 2022.

OUTLOOK

Industry performance will depend on the health of the global economy. Response to inflation will continue to control the housing and construction sectors during 2024. Product margins will depend on market supply and demand balances, feedstock and energy prices, supply chain interruptions, labor constraints and inflation. Sustained strong performance in the petroleum industry should strengthen the demand and margins for some of Occidental’s products that are consumed by industry participants. U.S. commodity export markets could be impacted by the relative strength of the U.S. dollar. Approximately $0.7 billion of Occidental’s worldwide capital budget is expected to be allocated to OxyChem in 2024.

BASIC CHEMICALS

Demand for basic chemicals is expected to improve moderately in 2024. Demand in most market segments is expected to follow the trend of the general economy throughout 2024. Demand for chlorine and derivatives should show gradual improvement across the year as both domestic and international growth slowly returns in most segments. Demand for alkali products should increase in 2024, as demand rebounds in all major segments, including pulp and paper, industrial, and alumina markets.

VINYLS

Single family housing starts steadily improved throughout 2023, offset by a declining multi-family housing market. Total housing starts are expected to be relatively flat next year, which will have little positive impact to domestic PVC demand in 2024. However, domestic infrastructure projects and recovering global demand are expected to slightly boost overall PVC demand year over year in 2024. New domestic PVC capacity will come online during 2024, which may have a negative impact on prices as the new production is placed into a bearish PVC market.

						MANAGEMENT’S DISCUSSION AND ANALYSIS


MIDSTREAM AND MARKETING SEGMENT

BUSINESS STRATEGY

The midstream and marketing segment strives to maximize value by optimizing the use of its gathering, processing, transportation, storage and terminal commitments and by providing the oil and gas segment access to domestic and international markets. To generate returns, the segment evaluates opportunities across the value chain and uses its assets to provide services to Occidental’s subsidiaries, as well as third parties. The midstream and marketing segment operates or contracts for services on gathering systems, gas plants, co-generation facilities and storage facilities and invests in entities that conduct similar activities.

This segment also seeks to minimize the costs of gas and power used in Occidental’s various businesses. Also included in the midstream and marketing segment is OLCV. OLCV seeks to leverage Occidental’s carbon management expertise through the development of CCUS projects, and invests in emerging low-carbon technologies that are expected to reduce Occidental’s carbon footprint and enable others to do the same. Capital is employed to sustain or expand assets to improve the competitiveness of Occidental’s businesses. In 2023, capital expenditures related to the midstream and marketing segment totaled $656 million, the majority of which were related to the construction of STRATOS.

BUSINESS ENVIRONMENT

Midstream and marketing segment earnings are affected by the performance of its various businesses, including its marketing, gathering and transportation, gas processing and power-generation assets. The marketing business aggregates, markets and stores Occidental and third-party volumes. Marketing performance is affected primarily by commodity price changes and margins in oil and gas transportation and storage programs. The marketing business results can experience significant volatility depending on commodity prices and the Midland-to-Gulf-Coast oil spreads. The Midland-to-Gulf-Coast oil spreads have decreased from an average of $0.36 per barrel in 2022 to $0.21 per barrel in 2023. A $0.25 change in the Midland-to-Gulf-Coast oil spreads impacts total year operating cash flows by approximately $65 million. Gas gathering, processing and transportation results are affected by fluctuations in commodity prices and the volumes that are processed and transported through the segment’s plants, as well as the margins obtained on related services from investments in which Occidental has an equity interest.

BUSINESS REVIEW

MARKETING

The marketing group markets substantially all of Occidental’s oil, NGL and natural gas production and optimizes its transportation and storage capacity. Occidental’s third-party marketing activities focus on purchasing oil, NGL and natural gas for resale from parties whose oil and gas supply is located near its transportation and storage capacity. These purchases allow Occidental to aggregate volumes to better utilize and optimize its assets. In 2023, compared to the prior year, marketing results were impacted by the timing of crude oil sales, partially offset by higher gas marketing margin from transportation capacity optimization.

DELIVERY AND TRANSPORTATION COMMITMENTS

Occidental has made long-term commitments to certain refineries and other buyers to deliver oil, NGL and natural gas. The total amount contracted to be delivered is approximately 58 MMbbl of oil through 2025, 795 MMbbl of NGL through 2034 and 812 Bcf of gas through 2029. The price for these deliveries is set at the time of delivery of the product.

Occidental has crude pipeline take-or-pay capacity of approximately 850 Mbbl/d to the Gulf Coast, leased crude storage capacity of approximately 10 MMbbl and capacity at the crude terminal of approximately 525 Mbbl/d. Certain of Occidental's crude pipeline take-or-pay agreements expire in 2025 and its Midstream business is well-positioned to benefit from potential reductions in crude oil transportation rates from the Permian to the Gulf Coast.

PIPELINE

Occidental’s pipeline business mainly consists of its 24.5% ownership interest in DEL. DEL owns and operates a 230-mile-long, 48-inch-diameter natural gas pipeline, known as the Dolphin Pipeline, which transports dry natural gas from Qatar to the UAE and Oman. The Dolphin Pipeline has capacity to transport up to 3.2 Bcf/d and currently transports approximately 2.0 Bcf/d and up to 2.2 Bcf/d in the summer months.

GAS PROCESSING, GATHERING AND CO2

Occidental processes its own and third-party domestic wet gas to extract NGL and other gas byproducts, including CO2 and delivers dry gas to pipelines. Margins primarily result from the difference between inlet costs of wet gas and market prices for NGL.

WES is a publicly traded limited partnership with its limited partner units traded on the NYSE under the ticker symbol “WES.” As of December 31, 2023, Occidental owned all of the 2.3% non-voting general partner interest, 48.8% of the WES limited partner units, and a 2% non-voting limited partner interest in WES Operating, a subsidiary of WES. As of December 31, 2023, Occidental's combined share of net income from WES and its subsidiaries was 51.0%. See Note 1 - Summary of


OXY 2023 FORM 10-K			43


						MANAGEMENT’S DISCUSSION AND ANALYSIS

Significant Accounting Policies in the Notes to Consolidated Financial Statements in Part II Item 8 of this Form 10-K for more information regarding Occidental’s equity method investment in WES. WES owns gathering systems, plants and pipelines and earns revenue from fee-based and service-based contracts with Occidental and third parties.

Occidental’s 40% participating interest in Al Hosn Gas also includes sour gas processing facilities that are designed to process 1.45 Bcf/d of natural gas and separate it into salable gas, condensate, NGL and sulfur. In 2023, the project produced 666 MMcf/d of natural gas, 95 Mbbl/d of NGL and condensate, and 12,450 tons/d of sulfur, of which Occidental’s net share was 267 MMcf/d of natural gas, 38 Mbbl/d of NGL and condensate and 4,980 tons/d of sulfur.

In 2023, compared to the prior year, gas processing, gathering and CO2 results decreased primarily due to lower sulfur and NGL prices.

POWER GENERATION FACILITIES

Earnings from power and steam generation facilities are derived from sales to affiliates and third parties.

LOW-CARBON VENTURES

OLCV was formed to execute on Occidental’s vision to reduce global emissions and provide a more sustainable future through the development of low-carbon energy and products. OLCV capitalizes on Occidental’s extensive experience in utilizing CO2 in its development of CCUS projects and providing services to third parties to facilitate the implementation of their CCUS projects. Moreover, OLCV is fostering emerging technologies, including DAC and low-carbon power sources, and other business models with the potential to position Occidental as a leader in the production of low-carbon energy and products.

Occidental has developed standards and protocols recognized by the EPA for monitoring, reporting and verifying the amount, safety and permanence of CO2 stored through secure geologic sequestration. Occidental holds four EPA-approved monitoring, reporting and verification plans for geologic sequestration through EOR production. OLCV has acquired access to over 300,000 acres of pore space to date, and has commenced permitting of Class VI CO2 sequestration wells with the EPA with the intention of developing five sequestration hubs on this acreage.

In March 2019, OLCV acquired an interest in NET Power, then a limited liability company based in Durham, North Carolina. NET Power is developing a low-cost, natural gas electric power system that generates near-zero emissions and inherently captures all CO2, unlocking the potential to produce electricity at a lower cost than existing power plants. In June 2023, OLCV invested an additional $351 million in NET Power as part of NET Power’s merger with a special purpose acquisition company. NET Power Inc. is currently traded on the NYSE under the symbol “NPWR.”

In May 2023, Occidental began the construction of STRATOS, the world’s largest direct air capture plant in Ector County, Texas. The facility, which uses Carbon Engineering’s technology, is expected to be commercially operational in mid-2025. In November 2023, Occidental entered into a joint venture agreement with BlackRock, through a fund managed by its Diversified Infrastructure business, for the development of STRATOS. The agreement provides $550 million of committed investment from BlackRock's fund.

In August 2023, Occidental entered into an agreement with Carbon Engineering Ltd., its equity method investee, to purchase the remaining 68% interest not already owned by Occidental or its affiliates for total cash consideration of approximately $1.1 billion, resulting in Carbon Engineering becoming a wholly owned subsidiary of Occidental. Because Occidental acquired control of Carbon Engineering in the 2023 purchase, Occidental remeasured its previously held 32% equity interest at its acquisition-date fair value and recognized a gain of $283 million. The purchase price will be made in three approximately equal annual payments, with the first payment made at closing. This transaction closed on November 3, 2023, and Occidental made the first payment of $349 million. The remaining two payments will be paid on the first and second anniversaries of closing. With this purchase Occidental intends to accelerate technological innovation and cost reductions in Carbon Engineering's direct air capture technology. The transaction qualifies as a business combination and was accounted for using the acquisition method of accounting.

OLCV is also currently conducting front-end engineering design work and feasibility studies on a number of projects to capture and sequester CO2, either from the atmosphere or from industrial point sources. The profitability of sequestration projects is dependent upon the costs of developing, building and operating sequestration infrastructure, demand for sequestration services from emitters and the availability of certain tax attributes and credits generated from the capture and storage of CO2.

In August 2022, Congress passed the Inflation Reduction Act that contains, among other provisions, certain tax incentives related to climate change and clean energy. These incentives may attract more third-party investment of OLCV’s projects which may help accelerate certain projects. The ultimate impact of the Inflation Reduction Act on Occidental’s emerging low-carbon businesses and net-zero pathway will depend on a number of factors, interpretations and assumptions as well as additional regulatory guidance.

OUTLOOK

Midstream and marketing segment results can experience volatility depending on commodity price changes, demand impacting export sales and the Midland-to-Gulf-Coast oil spreads. Gas gathering, processing and transportation results are affected by fluctuations in commodity prices and the volumes that are processed and transported through the segment’s plants, as well as the margins obtained on related services from investments in which Occidental has an equity interest.


44			OXY 2023 FORM 10-K


						MANAGEMENT’S DISCUSSION AND ANALYSIS

Throughout 2023, the U.S. experienced economy-wide cost increases, which could increase the cost of sequestration and other low-carbon projects. In 2023, increased interest from third parties in providing sequestration services or purchasing carbon credits indicated a growing market for OLCV products and services. Additionally, grants, credits and other tax-advantaged low-carbon attributes continue to be actively discussed at both state and federal levels. These trends of increasing interest from third parties and funding at state and federal levels are expected to continue, which Occidental believes will enhance the economics of CCUS projects.

Approximately $0.8 billion of Occidental’s worldwide capital budget is expected to be allocated to its midstream and marketing operations in 2024.

						MANAGEMENT’S DISCUSSION AND ANALYSIS

Domestic oil and gas results, excluding significant items affecting comparability, decreased in 2023 compared to 2022 primarily due to lower realized oil, NGL and natural gas prices and higher lease operating costs partially offset by higher sales volumes across all commodities. International oil and gas results, excluding significant items affecting comparability, decreased in 2023 compared to 2022 primarily due to lower oil prices.

Average Realized Prices

The following table sets forth the average realized prices for oil, NGL and natural gas from ongoing operations for each of the three years in the period ended December 31, 2023, and includes a year-over-year change calculation:

Please refer to the Supplemental Oil and Gas Information (unaudited) section of this Form 10-K for additional information on oil and gas production and sales.

Average daily production volumes from ongoing operations increased by 6% in 2023 as compared to 2022. The increase in production was primarily due to increased development activity in the Permian Basin, and the completion of the expansion project that increased the production capacity of the Al Hosn Gas processing facilities from 1.28 Bcf/d to 1.45 Bcf/d. which was partially offset by a decrease in oil production in Algeria resulting from new development agreement fiscal terms, which took effect May 3, 2023.

Lease Operating Expense

The following table sets forth the average lease operating expense per Boe from ongoing operations for each of the three years in the period ended December 31, 2023:


	2023		2022		2021
Average lease operating expense per Boe	$	10.48	$	9.52	$	7.58

Average lease operating expense per Boe increased in 2023 compared to 2022 primarily as a result of higher workover and maintenance activity in Occidental’s domestic operations.

(b)The 2023, 2022 and 2021 amounts included gains on sale of $51 million, $62 million and $102 million, respectively, from the sales of 5.1 million, 10.0 million and 11.5 million limited partner units in WES, respectively, The 2022 amount also included a $36 million gain on sale of a joint venture.

(c)The 2023 amount included derivative losses and charges reported under income from equity investments and other in the Consolidated Condensed Statement of Operations.

(d)The 2023 amount included a gain of $283 million from the remeasurement of the non-controlling interest held prior to the Carbon Engineering acquisition to fair value and acquisition-related costs of $20 million.

Midstream and marketing segment results, excluding items affecting comparability, decreased in 2023 compared to 2022, and was primarily driven by lower crude margins due to the timing of crude sales in the marketing business and lower NGL and sulfur prices impacting gas processing, increased activities in the low-carbon ventures businesses, and lower equity method investment income from WES.

						MANAGEMENT’S DISCUSSION AND ANALYSIS


INCOME TAXES

Total deferred tax assets, after valuation allowance, were $2.0 billion and $2.2 billion as of December 31, 2023 and 2022, respectively. Occidental expects to realize the recorded deferred tax assets, net of any allowances, through future operating income and reversal of temporary differences. The total deferred tax liabilities were $7.7 billion as of December 31, 2023 and 2022. See more discussion below.

WORLDWIDE EFFECTIVE TAX RATE

The following table sets forth the calculation of the worldwide effective tax rate for income from continuing operations:


millions	2023		2022		2021
SEGMENT RESULTS
Oil and gas	$	6,240	$	12,803	$	4,145
Chemical	1,531		2,508		1,544
Midstream and marketing	24		273		257
Unallocated corporate items	(1,366)		(1,467)		(2,241)
Income from continuing operations before taxes	$	6,429	$	14,117	$	3,705
Income tax benefit (expense)
Federal and state	(975)		248		(247)
Foreign	(758)		(1,061)		(668)
Total income tax expense	(1,733)		(813)		(915)
Income from continuing operations	$	4,696	$	13,304	$	2,790
Worldwide effective tax rate	27%		6%		25%

In 2023, Occidental’s worldwide effective tax rate was 27%, which was higher than the U.S. statutory rate of 21% and primarily driven by Occidental's jurisdictional mix of income, where international income is subject to tax at statutory rates as high as 55%.

LEGAL ENTITY REORGANIZATION

To align Occidental’s legal entity structure with the nature of its business activities after completing the Anadarko Acquisition and subsequent large scale post-acquisition divestiture program, management undertook a legal entity reorganization that was completed in the first quarter of 2022.

As a result of this legal entity reorganization, management made an adjustment to the tax basis in a portion of its operating assets, thus reducing Occidental’s deferred tax liabilities. Accordingly, in 2022, Occidental recorded a tax benefit of $2.7 billion in connection with this reorganization. The timing of any reduction in Occidental’s future cash taxes as a result of this legal entity reorganization will be dependent on a number of factors, including prevailing commodity prices, capital activity level and production mix. The legal entity reorganization transaction is currently under IRS review as part of the Company’s 2022 federal tax audit.

INFLATION REDUCTION ACT AND PILLAR TWO

In August 2022, Congress passed the IRA that contains, among other provisions, a corporate book minimum tax on financial statement income, an excise tax on stock buybacks, a methane emissions fee and certain tax incentives related to climate change and clean energy. Occidental is currently evaluating the guidance and proposed regulations released in 2023. The ultimate impact of the IRA to Occidental will depend on a number of factors including future commodity prices, interpretations and assumptions as well as additional regulatory guidance.

Approximately 140 countries have agreed to a statement in support of the OECD Pillar Two initiative that proposes a 15% global minimum tax on a jurisdiction by jurisdiction basis. A number of countries, including European Union member states, the United Kingdom, and Canada have enacted or are expected to enact legislation to be effective as early as 2024, with widespread implementation of a global minimum tax expected by 2025. As the legislation becomes effective in countries in which Occidental operates, its cash tax could increase and its effective tax rate could be negatively impacted. Occidental will continue to monitor proposed legislation and guidance issued by both the OECD as well as the jurisdictions in which it operates to assess the impact on its tax position.

NET SALES

Price and volume changes generally represent the majority of the change in the oil and gas and chemical segments sales. Midstream and marketing sales generally represent the margins earned by the marketing business as it strives to optimize the use of its transportation, storage and terminal commitments to provide access to domestic and international markets and, to a lesser extent, NGL and sulfur revenues from the gas processing business.

The decrease in net sales in 2023 compared to 2022 was primarily due to lower worldwide crude oil, domestic NGL and domestic natural gas commodity prices in the oil and gas segment, lower realized PVC and caustic sales prices and lower sales volumes across most product lines in the chemical segment and lower sales in the marketing business, partially offset by higher domestic sales volumes in the oil and gas segment.

OIL AND GAS OPERATING EXPENSE

Oil and gas operating expense increased in 2023 compared to 2022, primarily as a result of higher workover and maintenance activity in Occidental’s domestic operations.

CHEMICAL AND MIDSTREAM COST OF SALES

Chemical and midstream cost of sales decreased in 2023 compared to 2022, primarily as a result of lower ethylene and energy cost in the chemical segment and lower power generation cost of sales in the midstream and marketing segment.

PURCHASED COMMODITIES

Purchased commodities decreased in 2023 compared to 2022, due to lower volumes and prices on third-party crude purchases in the midstream and marketing segment.

SELLING, GENERAL, AND ADMINISTRATIVE

Selling, General, and Administrative increased in 2023 compared to 2022, due to increased employee and technology costs.

OTHER OPERATING AND NON-OPERATING EXPENSE

Other operating and non-operating expense decreased in 2023 compared to 2022, primarily due to the $260 million adjustment of the valuation allowance for the Maxus Liquidating Trust.


OXY 2023 FORM 10-K			51


						MANAGEMENT’S DISCUSSION AND ANALYSIS

TAXES OTHER THAN ON INCOME

Taxes other than on income in 2023 decreased compared to 2022, primarily due to decreases in production taxes and Rockies ad valorem taxes, which are directly tied to revenues.

ASSET IMPAIRMENTS AND OTHER CHARGES

Asset impairments in 2023 included a pre-tax impairment of $180 million related to undeveloped acreage in the northern non-core area of the Powder River Basin and a $29 million impairment related to an equity method investment in the Black Butte Coal Company.

EXPLORATION EXPENSE

Exploration expense increased in 2023 compared to 2022, primarily due to higher dry hole expense in the Gulf of Mexico.

INTEREST AND DEBT EXPENSE, NET

Interest and debt expense decreased in 2023 compared to 2022, due to lower outstanding debt as a result of $9.5 billion of debt repayments in 2022, partially offset by early debt extinguishment costs incurred in 2022.

INCOME FROM EQUITY INVESTMENTS AND OTHER

Income from equity investments and other decreased in 2023 compared to 2022, primarily due to lower equity income from WES and charges recorded by NET Power in relation to their public offering.

INCOME TAX EXPENSE

Income tax expense increased in 2023 compared to 2022, primarily as a result of a $2.7 billion tax benefit taken in 2022 related to a legal entity reorganization.


LIQUIDITY AND CAPITAL RESOURCES

CASH ON HAND

As of December 31, 2023, Occidental had approximately $1.4 billion in cash and cash equivalents. A substantial majority of this cash is held and available for use in the United States.

SOURCES AND USES OF CASH

Occidental currently expects its operational cash flows and cash on hand along with the committed CrownRock Acquisition financing to be sufficient to meet its current debt maturities and other obligations for the next 12 months from the date of this filing. Occidental’s $4.0 billion RCF, receivables securitization facility and access to capital markets are available to meet its ongoing capital needs, purchase obligations, near-term debt maturities and other liabilities and financial obligations, if required.

The RCF maturity date is June 30, 2025. In February 2024, Occidental entered into a Third Amended and Restated Credit Agreement with the same committed borrowing capacity as above, but extended the maturity date to June 30, 2028. No amounts were drawn under the facility as of December 31, 2023.

Occidental’s planned 2024 capital expenditures are between $6.4 billion and $6.6 billion.

As of December 31, 2023, Occidental had $1.1 billion in current maturities of long-term debt which are due in 2024, and an additional $1.2 billion in long-term obligations due in 2025.

As of December 31, 2023, Occidental had $599 million in non-cancelable lease payments due in 2024, and an additional $427 million in non-cancelable lease payments due in 2025.

Dividends paid to common and preferred shareholders were $1.4 billion in 2023.

Occidental is party to various purchase agreements that are not accounted for as leases or otherwise accrued as liabilities as of December 31, 2023. These agreements consist primarily of obligations to secure terminal, pipeline and processing capacity, purchase services used in the normal course of business including transporting and disposing of produced water, purchase goods used in the production of finished goods including certain chemical raw materials and power and agreements relating to equipment maintenance and service. Refer to the line item “Purchase Obligations” in the

						MANAGEMENT’S DISCUSSION AND ANALYSIS

table below under Contractual Obligations for the amounts that will be paid for such outstanding off-balance sheet purchase obligations from 2024 and thereafter.

CROWNROCK ACQUISITION FINANCING

In connection with the planned CrownRock Acquisition, Occidental has secured a fully-committed $5.3 billion bridge loan facility, a $2.0 billion 364-day term loan, and a $2.7 billion two-year term loan. Prior to or concurrent with the closing of the acquisition, Occidental plans to issue new debt comprised of a combination of the one and two-year term loans and senior unsecured notes. In addition, Occidental plans to refinance a majority of the $1.2 billion of CrownRock’s existing debt assumed in the acquisition. Occidental intends to repay at least $4.5 billion of debt within 12 months of closing the CrownRock Acquisition with proceeds from the divestiture program and excess cash flows.

DIVESTITURE PROGRAM

In the fourth quarter of 2023, Occidental announced a divestiture program between $4.5 billion and $6.0 billion, which Occidental expects to complete within 18 months of closing the CrownRock Acquisition.

SHARE REPURCHASE PROGRAM

In February 2023, the Board authorized a new share repurchase program of up to $3.0 billion of Occidental’s shares of common stock. During 2023, Occidental purchased a total of 29.1 million shares under the share repurchase program for $1.8 billion and the value remaining as of December 31, 2023 was $1.2 billion.

PREFERRED REDEMPTIONS

In connection with the Anadarko Acquisition, Occidental issued 100,000 shares of series A preferred stock, with a face value of $100,000 per share and a liquidation preference of $105,000 per share plus unpaid accrued dividends. Prior to August 2029, a mandatory redemption provision obligates Occidental to redeem preferred stock at a 10% premium to face value on a dollar-for-dollar basis for every dollar distributed to common shareholders (either via common stock dividends or share repurchases) above $4.00 per share, on a trailing 12-month basis. Preferred redemptions can settle between 30 and 60 days from the date Berkshire Hathaway is notified of the redemption obligation and accrued unpaid dividends are paid up to but not including the redemption date. Occidental cannot voluntarily redeem preferred stock before August 2029. After August 2029, Occidental can voluntarily redeem preferred stock at a 5% premium to face value.

Dividends on the preferred stock accrue on the face value at a rate per annum of 8%, but will be paid only when, as and if declared by Occidental’s Board of Directors. At any time, when such dividends have not been paid in full, the unpaid amounts will accrue dividends, compounded quarterly, at a rate per annum of 9%. Following the payment in full of any accrued but unpaid dividends, the dividend rate will remain at 9% per annum. If preferred dividends are not paid in full, Occidental is prohibited from paying dividends on common stock. Occidental paid $762 million in preferred stock dividends in 2023.

In 2023, Occidental redeemed preferred stock with a face value of $1.5 billion, and incurred $151 million in redemption premiums. To the extent Occidental's trailing 12-month distributions to common shareholders is above $4.00 per share, Occidental is required to match any common shareholder distributions with preferred stock redemptions. As of the date of this filing approximately $8.5 billion face value of the preferred stock remains outstanding.

						MANAGEMENT’S DISCUSSION AND ANALYSIS


CRITICAL ACCOUNTING POLICIES AND ESTIMATES

The process of preparing financial statements in accordance with United States GAAP requires Occidental’s management to make informed estimates and judgments regarding certain items and transactions. Changes in facts and circumstances or discovery of new information may result in revised estimates and judgments and actual results may differ from these estimates upon settlement but generally not by material amounts. The selection and development of these policies and estimates have been discussed with the Audit Committee of the Board of Directors. Occidental considers the following to be its most critical accounting policies and estimates that involve management’s judgment.

OIL AND GAS PROPERTIES

The carrying value of Occidental’s PP&E represents the cost incurred to acquire or develop the asset, including any AROs and capitalized interest, net of DD&A and any impairment charges. For assets acquired in a business combination, PP&E cost is based on fair values at the acquisition date. AROs and interest costs incurred in connection with qualifying capital expenditures are capitalized and amortized over the useful lives of the related assets.

Occidental uses the successful efforts method to account for its oil and gas properties. Under this method, Occidental capitalizes costs of acquiring properties, costs of drilling successful exploration wells and development costs. The costs of exploratory wells are initially capitalized pending a determination of whether proved reserves have been found. If proved reserves have been found, the costs of exploratory wells remain capitalized. For exploratory wells that find reserves that cannot be classified as proved when drilling is completed, costs continue to be capitalized as suspended exploratory drilling costs if there have been sufficient reserves found to justify completion as a producing well and sufficient progress is being made in assessing the economic and operating viability of the project. At the end of each quarter, management reviews the status of all suspended exploratory drilling costs in light of ongoing exploration activities and in particular, whether Occidental is making sufficient progress in its ongoing exploration and appraisal efforts or, in the case of discoveries requiring government sanctioning, analyzing whether development negotiations are underway and proceeding as planned. If management determines that future appraisal drilling or development activities are unlikely to occur, associated suspended exploratory well costs are expensed.

Occidental expenses annual lease rentals, the costs of injectants used in production and geological and geophysical costs as incurred for exploration activities.

Occidental determines depreciation and depletion of oil and gas producing properties by the unit-of-production method. It amortizes leasehold acquisition costs over total proved reserves and capitalized development and successful exploration costs over proved developed reserves.

Several factors could change Occidental’s proved oil and gas reserves. For example, Occidental receives a share of production from PSCs to recover its costs and generally an additional share for profit. Occidental’s share of production and reserves from these contracts decreases when product prices rise and increases when prices decline. Generally, Occidental’s net economic benefit from these contracts is greater at higher product prices. In other cases, particularly with long-lived properties, lower product prices may lead to a situation where production of a portion of proved reserves becomes uneconomical. For such properties, higher product prices typically result in additional reserves becoming economical. Estimation of future production and development costs is also subject to change partially due to factors beyond Occidental’s control, such as energy costs and inflation or deflation of oil field service costs. These factors, in turn, could lead to changes in the quantity of proved reserves. Additional factors that could result in a change of proved reserves include production decline rates and operating performance differing from those estimated when the proved reserves were initially recorded. Changes in the political and regulatory climate, including new or amended laws and regulations or changes in the interpretation of those laws and regulations, could lead to decreases in proved reserves as development horizons may be extended into the future, changes to development locations are necessary or the changes result in higher development or operating costs.

Occidental performs impairment tests with respect to its proved properties whenever events or circumstances indicate that the carrying value of property may not be recoverable. If there is an indication the carrying amount of the asset may not be recovered due to significant and prolonged declines in current and forward prices, significant changes in reserve estimates, changes in management’s plans or other significant events, management will evaluate the property for impairment. Under the successful efforts method, if the sum of the undiscounted cash flows is less than the carrying value of the proved property, the carrying value is reduced to estimated fair value and reported as an impairment charge in the period. Individual proved properties are grouped for impairment purposes at the lowest level for which there are identifiable cash flows unless observable and comparable transactions are available. The fair value of impaired assets is typically determined based on the present value of expected future cash flows using discount rates believed to be consistent with those used by market participants. The impairment test incorporates a number of assumptions involving expectations of


OXY 2023 FORM 10-K			57


						MANAGEMENT’S DISCUSSION AND ANALYSIS

future cash flows which can change significantly over time. These assumptions include estimates of future production, product prices, contractual prices, estimates of risk-adjusted oil and gas proved and unproved reserves and estimates of future operating and development costs. It is reasonably possible that prolonged declines in commodity prices, reduced capital spending in response to lower prices or increases in operating costs could result in impairments.

For impairment testing, unless prices are contractually fixed, Occidental uses observable forward strip prices for oil and natural gas prices when projecting future cash flows. Future operating and development costs are estimated using the current cost environment applied to expectations of future operating and development activities to develop and produce oil and gas reserves. Market prices for oil, NGL and natural gas have been volatile and may continue to be volatile in the future. Changes in global supply and demand, transportation capacity, currency exchange rates, applicable laws and regulations and the effect of changes in these variables on market perceptions could impact current forecasts. Future fluctuations in commodity prices could result in estimates of future cash flows to vary significantly.

Net capitalized costs attributable to unproved properties were $10.2 billion as of December 31, 2023, and $12.6 billion as of December 31, 2022. The unproved amounts are not subject to DD&A until they are classified as proved properties. Individually insignificant unproved properties are combined and amortized on a group basis based on factors such as geographic location, lease terms, success rates and other factors to provide for full amortization upon lease expiration or abandonment.

Significant unproved properties are assessed individually for impairment and when events or circumstances indicate that the carrying value of property may not be recovered a valuation allowance is provided if an impairment is indicated. Occidental periodically reviews significant unproved properties for impairments; numerous factors are considered, including but not limited to, availability of funds for future exploration and development activities, current exploration and development plans, favorable or unfavorable exploration activity on the property or the adjacent property, geologists’ evaluation of the property, the current and projected political and regulatory climate, contractual conditions and the remaining lease term for the properties. If an impairment is indicated, Occidental will first determine whether a comparable transaction for similar properties or implied acreage valuation derived from domestic onshore market participants is available and will adjust the carrying amount of the unproved property to its fair value using the market approach. In situations where the market approach is not observable and unproved reserves are available, undiscounted future net cash flows used in the impairment analysis are determined based on managements’ risk adjusted estimates of unproved reserves, future commodity prices and future costs to produce the reserves. If undiscounted future net cash flows are less than the carrying value of the property, the future net cash flows are discounted and compared to the carrying value for determining the amount of the impairment loss to record. Occidental utilizes the same assumptions and methodology discussed above for cash flows associated with proved properties.

PROVED RESERVES

Occidental estimates its proved oil and gas reserves according to the definition of proved reserves provided by the SEC’s Rule 4-10 (a) of Regulation S-X and Financial Accounting Standards Board. Proved oil and gas reserves are those quantities of oil and gas which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible—from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations—prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. Prices include consideration of price changes provided only by contractual arrangements and do not include adjustments based on expected future conditions. For reserves information, see the Supplemental Information on Oil and Gas Exploration and Production Activities under Item 8 of this Form 10-K.

Engineering estimates of the quantities of proved reserves are inherently imprecise and represent only approximate amounts because of the judgments involved in developing such information. Occidental’s estimates of proved reserves are made using available geological and reservoir data as well as production performance data. The reliability of these estimates at any point in time depends on both the quality and quantity of the technical and economic data and the efficiency of extracting and processing the hydrocarbons. These estimates are reviewed annually by internal reservoir engineers and revised, either upward or downward, as warranted by additional data. Revisions are necessary due to changes in, among other things, development plans, reservoir performance, prices, economic conditions and government restrictions as well as changes in the expected recovery associated with infill drilling. Decreases in prices, for example, may cause a reduction in some proved reserves due to reaching economic limits at an earlier projected date. A material adverse change in the estimated volume of proved reserves could have a negative impact on DD&A and could result in property impairments.

The most significant ongoing financial statement effect from a change in Occidental’s oil and gas reserves or impairment of its proved properties would be to the DD&A rate. For example, a 5% increase or decrease in the amount of oil and gas reserves would change the DD&A rate by approximately $0.65/Bbl, which would increase or decrease pre-tax income by approximately $290 million annually at current production rates.

FAIR VALUES

Occidental estimates fair-value of long-lived assets for impairment testing, assets and liabilities acquired in a business combination or exchanged in non-monetary transactions, pension plan assets and initial measurements of AROs.


58			OXY 2023 FORM 10-K


						MANAGEMENT’S DISCUSSION AND ANALYSIS

Accounting for the acquisition of a business requires the allocation of the purchase price to the various assets and liabilities of the acquired business and recording deferred taxes for any differences between the allocated values and tax basis of assets and liabilities. Any excess of the purchase price over the amounts assigned to assets and liabilities is recorded as goodwill. The purchase price allocation is accomplished by recording each asset and liability at its estimated fair value, which may be determined using different methods of fair value measurements, largely based on the availability and quality of market information. Occidental primarily applies the market approach for recurring fair value measurements, maximizes its use of observable inputs and minimizes its use of unobservable inputs.

FINANCIAL ASSETS AND LIABILITIES

Occidental utilizes published prices or counterparty statements for valuing the majority of its financial assets and liabilities measured and reported at fair value. In addition to using market data, Occidental makes assumptions in valuing its assets and liabilities, including assumptions about the risks inherent in the inputs to the valuation technique. For financial assets and liabilities carried at fair value, Occidental measures fair value using the following methods:

■Occidental values exchange-cleared commodity derivatives using closing prices provided by the exchange as of the balance sheet date. These derivatives are classified as using quoted prices in active markets for the assets or liabilities (Level 1).

■OTC bilateral financial commodity contracts, international exchange contracts, options and physical commodity forward purchase and sale contracts are generally classified as using observable inputs other than quoted prices for the assets or liabilities (Level 2) and are generally valued using quotations provided by brokers or industry-standard models that consider various inputs, including quoted forward prices for commodities, time value, volatility factors, credit risk and current market and contractual prices for the underlying instruments, as well as other relevant economic measures. Substantially all of these inputs are observable in the marketplace throughout the full term of the instrument and can be derived from observable data or are supported by observable prices at which transactions are executed in the marketplace.

■Occidental values commodity derivatives based on a market approach that considers various assumptions, including quoted forward commodity prices and market yield curves. The assumptions used include inputs that are generally unobservable in the marketplace or are observable but have been adjusted based upon various assumptions and the fair value is designated as using unobservable inputs (Level 3) within the valuation hierarchy.

■Occidental values debt using market-observable information for debt instruments that are traded on secondary markets. For debt instruments that are not traded, the fair value is determined by interpolating the value based on debt with similar terms and credit risk.

NON-FINANCIAL ASSETS

Occidental uses market-observable prices for assets when comparable transactions can be identified that are similar to the asset being valued. When Occidental is required to measure fair value and there is not a market-observable price for the asset or for a similar asset then the cost or income approach is used depending on the quality of information available to support management’s assumptions. The cost approach is based on management’s best estimate of the current asset replacement cost. The income approach is based on management’s best assumptions regarding expectations of future net cash flows and the expected cash flows are discounted using a commensurate risk-adjusted discount rate. Such evaluations involve significant judgment. The results are based on expected future events or conditions such as sales prices, estimates of future oil and gas production or throughput, development and operating costs and the timing thereof, economic and regulatory climates and other factors, most of which are often outside of management’s control. However, assumptions used reflect a market participant’s view of long-term prices, costs and other factors and are consistent with assumptions used in Occidental’s business plans and investment decisions.

ENVIRONMENTAL LIABILITIES AND EXPENDITURES

Certain subsidiaries of Occidental incur environmental liabilities and expenditures that relate to current operations and are expensed or capitalized by such subsidiaries as appropriate. Certain subsidiaries also incur environmental liabilities and expenditures with respect to remediation of existing conditions from alleged past practices at Third-Party, Currently Operated, and Closed or Non-operated Sites, which categories may include NPL sites. Those environmental liabilities and related charges and expenses for estimated remediation costs from past operations are recorded when environmental remediation efforts are probable and the costs can be reasonably estimated. Occidental discloses such remediation liabilities on a consolidated basis. In determining the environmental remediation liability and the range of reasonably possible additional losses, Occidental refers to currently available information, including relevant past experience, remedial objectives, available technologies, applicable laws and regulations and cost-sharing arrangements. These environmental remediation liabilities are based on management’s estimate of the most likely cost to be incurred, using the most cost-effective technology reasonably expected to achieve the remedial objective. Occidental periodically reviews these environmental remediation liabilities and adjusts them as new information becomes available. Occidental’s subsidiaries generally record reimbursements or recoveries of environmental remediation costs in income when received, or when receipt of recovery is highly probable.


OXY 2023 FORM 10-K			59


						MANAGEMENT’S DISCUSSION AND ANALYSIS

Many factors could affect future remediation costs incurred by Occidental’s subsidiaries and result in adjustments to environmental remediation liabilities and the range of reasonably possible additional losses. The most significant are: (1) cost estimates for remedial activities may vary from the initial estimate; (2) the length of time, type or amount of remediation necessary to achieve the remedial objective may change due to factors such as site conditions, the ability to identify and control contaminant sources or the discovery of additional contamination; (3) a regulatory agency may ultimately reject or modify proposed remedial plans; (4) improved or alternative remediation technologies may change remediation costs; (5) laws and regulations may change remediation requirements or affect cost sharing or allocation of liability; and (6) changes in allocation or cost-sharing arrangements may occur.

Certain sites involve multiple parties with various cost-sharing arrangements, which generally fall into the following three categories: (1) environmental proceedings that result in a negotiated or prescribed allocation of remediation costs among the affected Occidental’s subsidiary and other alleged potentially responsible parties; (2) oil and gas ventures in which each participant pays its proportionate share of remediation costs reflecting its working interest; or (3) contractual arrangements, typically relating to purchases and sales of properties, in which the parties to the transaction agree to methods of allocating remediation costs. In these circumstances, the affected subsidiary evaluates the financial viability of other parties with whom it is alleged to be jointly liable, the degree of their commitment to participate and the consequences to such subsidiary of their failure to participate when estimating its ultimate share of liability. Occidental subsidiaries record environmental remediation liabilities at their expected net cost of remedial activities. Based on these factors, except as otherwise disclosed in Note 12 - Environmental Liabilities and Expenditures in the Notes to Consolidated Financial Statements in Part II Item 8 of this Form 10-K, Occidental’s subsidiaries believe that they will not be required to assume a share of liability of such other potentially responsible parties in an amount materially above amounts reserved.

In addition to the costs of investigations and clean-up measures, which often take in excess of 10 years at CERCLA NPL sites, Occidental subsidiaries’ environmental remediation liabilities include estimates of the costs to operate and maintain remedial systems. If remedial systems are modified over time in response to significant changes in site-specific data, laws, regulations, technologies or engineering estimates, Occidental’s subsidiaries review and adjust their environmental remediation liabilities accordingly.

If Occidental or its subsidiaries were to adjust the balance of their environmental remediation liabilities based on the factors described above, the amount of the increase or decrease would be recognized in earnings. For example, if the balance were reduced by 10%, Occidental would record a pre-tax increase to income of $102 million. If the balance were increased by 10%, Occidental would record an additional remediation expense of $102 million.

INCOME TAXES

Occidental and its subsidiaries file various U.S. federal, state and foreign income tax returns. The impact of changes in tax regulations are reflected when enacted. In general, deferred federal, state and foreign income taxes are provided on temporary differences between the financial statement carrying amounts of assets and liabilities and their respective tax basis. Occidental routinely assesses the realizability of its deferred tax assets. If Occidental concludes that it is more likely than not that some of the deferred tax assets will not be realized, the tax asset is reduced by a valuation allowance. Occidental recognizes a tax benefit from an uncertain tax position when it is more likely than not that the position will be sustained upon examination, based on the technical merits of the position. The tax benefit recorded is equal to the largest amount that is greater than 50% likely to be realized through final settlement with a taxing authority. Interest and penalties related to unrecognized tax benefits are recognized in income tax expense (benefit). See Note 10 - Income Taxes in the Notes to Consolidated Financial Statements in Part II Item 8 of this Form 10-K.

LOSS CONTINGENCIES

Occidental or certain of its subsidiaries are involved, in the normal course of business, in lawsuits, claims and other legal proceedings and audits. Occidental or its affected subsidiaries, as appropriate, accrues reserves for these matters when it is probable that a liability has been incurred and the liability can be reasonably estimated. In addition, Occidental discloses, in aggregate on a consolidated basis, exposure to loss in excess of the amount recorded on the balance sheet for these matters if it is reasonably possible that an additional material loss may be incurred. Occidental reviews such loss contingencies on an ongoing basis.

Loss contingencies are based on judgments made by management with respect to the likely outcome of these matters and are adjusted as appropriate. Management’s judgments could change based on new information, changes in, or interpretations of, laws or regulations, changes in management’s plans or intentions, opinions regarding the outcome of legal proceedings or other factors. See Note 13 - Lawsuits, Claims, Commitments and Contingencies in the Notes to Consolidated Financial Statements in Part II Item 8 of this Form 10-K for additional information.

						QUANTITATIVE AND QUALITATIVE DISCLOSURES

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK


COMMODITY PRICE RISK

GENERAL

Occidental’s results are sensitive to fluctuations in oil, NGL and natural gas prices. Price changes at current global prices and levels of production affect Occidental’s budgeted 2024 pre-tax annual income by approximately $215 million for a $1 per barrel change in oil prices and approximately $25 million for a $1 per barrel change in NGL prices. If domestic natural gas prices varied by $0.10 per Mcf, it would have an estimated annual effect on Occidental’s budgeted 2024 pre-tax income of approximately $36 million. These price-change sensitivities include the impact of PSC and similar contract volume changes on income. If production levels differ from Occidental’s 2024 budgeted production, the sensitivity of Occidental’s results to prices also will change. Marketing results are sensitive to price changes of oil, natural gas and, to a lesser degree, other commodities. A $0.25 change in the Midland-to-Gulf-Coast oil spreads impacts budgeted 2024 operating cash flows by approximately $65 million.

Occidental’s results are also sensitive to fluctuations in chemical prices. A variation in chlorine and caustic soda prices of $10 per ton would have a pre-tax annual effect on income of approximately $10 million and $30 million, respectively. A variation in PVC prices of $0.01 per lb. would have a pre-tax annual effect on income of approximately $30 million. Historically, over time, product price changes have tracked raw material and feedstock product price changes, somewhat mitigating the effect of price changes on margins.

RISK MANAGEMENT

Occidental conducts its risk management activities for marketing and trading under the controls and governance of its risk control policies. The controls under these policies are implemented and enforced by a risk management group which monitors risk by providing an independent and separate evaluation and check. Members of the risk management group report to the Corporate Vice President and Treasurer. Controls for these activities include limits on value at risk, limits on credit, limits on total notional trade value, segregation of duties, delegation of authority, daily price verifications, reporting to senior management on various risk measures and a number of other policy and procedural controls.

FAIR VALUE OF MARKETING DERIVATIVE CONTRACTS

Occidental carries derivative contracts it enters into in connection with its marketing activities at fair value. Fair values for these contracts are derived from Level 1 and Level 2 sources. The fair values in future maturity periods are insignificant.

The following table shows the fair value of Occidental’s derivatives (excluding collateral), segregated by maturity periods and by methodology of fair value estimation:


	Maturity Periods
Source of Fair Value Assets (Liabilities) millions	2024		2025 and 2026		2027 and 2028		2029 and thereafter		Total
Prices actively quoted	$	44	$	—	$	—	$	—	$	44
Prices provided by other external sources	36		(4)		—		—		32
Total	$	80	$	(4)	$	—	$	—	$	76

QUANTITATIVE INFORMATION

Occidental uses value at risk to estimate the potential effects of changes in fair values of commodity contracts used in trading activities. This measure determines the maximum potential negative one day change in fair value with a 95% level of confidence. Additionally, Occidental uses complementary trading limits including position and tenor limits and maintains liquid positions as a result of which market risk typically can be neutralized or mitigated on short notice. As a result of these controls, Occidental believes that the market risk of its trading activities is not reasonably likely to have a material adverse effect on its performance.


62			OXY 2023 FORM 10-K


						QUANTITATIVE AND QUALITATIVE DISCLOSURES


INTEREST RATE RISK

GENERAL

As of December 31, 2023, Occidental had fixed rate debt with a fair value of $18.0 billion outstanding. A 25-basis point change in Treasury rates would change the fair value of the fixed rate debt approximately $282 million.

The table below provides information about Occidental’s long-term debt obligations. Debt amounts represent principal payments by maturity date.


millions except percentages	U.S. Dollar Fixed-Rate Debt		U.S. Dollar Variable-Rate Debt		Total (a)

2025	1,208		—		1,208
2026	1,448		—		1,448
2027	903		—		903
2028	906		—		906

Weighted-average interest rate	5.91%		5.75%		5.91%
Fair Value	$	18,011	$	68	$	18,079

(a)Excluded net unamortized debt premiums of $1.2 billion and debt issuance costs of $106 million.


FOREIGN CURRENCY RISK

Occidental’s international operations have limited currency risk. Occidental manages its exposure primarily by balancing monetary assets and liabilities and limiting cash positions in foreign currencies to levels necessary for operating purposes. A vast majority of international oil sales are denominated in United States dollars. Additionally, all of Occidental’s consolidated international oil and gas subsidiaries have the United States dollar as the functional currency. The effect of exchange rates on transactions in foreign currencies is included in periodic income.


CREDIT RISK

The majority of Occidental’s counterparty credit risk is related to the physical delivery of energy commodities to its customers and any inability of these customers to meet their settlement commitments. Occidental manages credit risk by selecting counterparties that it believes to be financially strong, by entering into netting arrangements with counterparties and by requiring collateral or other credit risk mitigants, as appropriate. Occidental actively evaluates the creditworthiness of its counterparties, assigns appropriate credit limits and monitors credit exposures against those assigned limits. Occidental also enters into futures contracts through regulated exchanges with select clearinghouses and brokers, which are subject to minimal credit risk, if any.

As of December 31, 2023, the substantial majority of the credit exposures were with investment grade counterparties. Occidental believes its exposure to credit-related losses as of December 31, 2023, was not material and losses associated with credit risk have been insignificant for all years presented.

						FINANCIAL STATEMENTS REPORT

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors

Occidental Petroleum Corporation:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Occidental Petroleum Corporation and subsidiaries (the Company) as of December 31, 2023 and 2022, the related consolidated statements of operations, comprehensive income, equity, and cash flows for each of the years in the three-year period ended December 31, 2023, and the related notes and financial statement schedule II - valuation and qualifying accounts (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2023, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 14, 2024 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Assessment of the estimated proved oil and gas reserves on the determination of depreciation and depletion expense for proved oil and gas properties.

As discussed in Note 1 to the consolidated financial statements, the Company determines depreciation and depletion of oil and gas producing properties by the unit-of-production method. Under this method, capitalized costs are amortized over estimated proved reserves. For the year ended December 31, 2023, the Company recorded depreciation and depletion expense related to proved oil and gas properties of $6.1 billion.

We identified the assessment of the estimated proved oil and gas reserves on the determination of depreciation and depletion expense related to proved oil and gas properties as a critical audit matter. Complex auditor judgment was required to assess the Company’s estimate of proved oil and gas reserves, which is a key input for the determination of depreciation and depletion expense. Estimating proved oil and gas reserves requires the expertise of professional petroleum reservoir engineers. The key assumptions included (1) estimated future production quantities and (2) estimated operating and capital costs.


OXY 2023 FORM 10-K			65


						FINANCIAL STATEMENTS REPORT

depletion process, including the estimation of proved oil and gas reserves. We analyzed and assessed the determination of depreciation and depletion expense for compliance with industry and regulatory standards. We assessed compliance of the methodology used by the Company’s engineering and technical staff to estimate proved oil and gas reserves with industry and regulatory standards. We read the findings of the independent reservoir engineering specialist’s review of the methods and procedures used by the Company in estimating the proved reserves for compliance with industry and regulatory standards. To assess the Company’s ability to accurately estimate future production quantities, we compared the future production quantity assumptions used by the Company in prior periods to the actual production amounts. We compared the estimated future production quantities used by the Company in the current period to historical production rates. We evaluated the operating and capital cost assumptions used by the Company’s engineering and technical staff by comparing them to historical costs. We evaluated the professional qualifications and the knowledge, skills, and ability of the Company’s internal reserve engineers and the independent reservoir engineering specialists engaged by the Company.

Evaluation of the environmental liability associated with the lower 8.3 miles of the Lower Passaic River site.

As discussed in Notes 1 and 12 to the consolidated financial statements, the Company accrues a liability for estimated environmental remedial activities when it is probable a liability has been incurred and the amount of remediation costs can be estimated. The Company accrued a liability related to its estimated allocable share of the costs to perform the remedial activities required for the lower 8.3 miles of the Lower Passaic River site. As of December 31, 2023, the Company’s total estimated environmental liabilities were $1.0 billion, which includes the estimated environmental liability for the lower 8.3 miles of the Lower Passaic River site.

We identified the evaluation of the environmental liability associated with the lower 8.3 miles of the Lower Passaic River site as a critical audit matter. There was a high degree of subjective auditor judgment in applying and evaluating the results of our procedures due to possible changes to the Company’s estimated allocable share of the remediation costs.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls over the Company’s environmental liability process to estimate the Company’s allocable share of the remediation costs associated with the lower 8.3 miles of the Lower Passaic River site. We assessed the Company’s assumption for its allocable share of the remediation costs and analyzed publicly available data sources for information that might be contrary to the information used by the Company. We involved an environmental analysis professional with specialized skills and knowledge who assisted in the evaluation of information used by management including publicly available data sources.

						FINANCIAL STATEMENTS REPORT

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors

Occidental Petroleum Corporation:

Opinion on Internal Control Over Financial Reporting

We have audited Occidental Petroleum Corporation and subsidiaries' (the Company) internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2023 and 2022, the related consolidated statements of operations, comprehensive income, equity, and cash flows for each of the years in the three-year period ended December 31, 2023, and the related notes and financial statement schedule II - valuation and qualifying accounts (collectively, the consolidated financial statements), and our report dated February 14, 2024 expressed an unqualified opinion on those consolidated financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Annual Assessment of and Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

						FINANCIAL STATEMENTS FOOTNOTES


Notes to Consolidated Financial Statements			Occidental Petroleum Corporation and Subsidiaries


NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

NATURE OF OPERATIONS

Occidental conducts its operations through various subsidiaries and affiliates. Occidental’s principal businesses consist of three reporting segments: oil and gas, chemical and midstream and marketing. The oil and gas segment explores for, develops and produces oil (which includes condensate), NGL and natural gas. OxyChem primarily manufactures and markets basic chemicals and vinyls. The midstream and marketing segment purchases, markets, gathers, processes, transports and stores oil (which includes condensate), NGL, natural gas, CO2 and power. It also optimizes its transportation and storage capacity, and invests in entities that conduct similar activities, such as WES.

PRINCIPLES OF CONSOLIDATION

The Consolidated Financial Statements have been prepared in conformity with GAAP and include the accounts of Occidental, its subsidiaries, its undivided interests in oil and gas exploration and production ventures and, previously, variable interest entities, for which Occidental was the primary beneficiary. Occidental accounts for its share of oil and gas exploration and production ventures by reporting its proportionate share of assets, liabilities, revenues, costs and cash flows within the relevant lines on the balance sheets, statements of operations and statements of cash flows.

INVESTMENTS IN UNCONSOLIDATED ENTITIES

Occidental’s percentage interest in the underlying net assets of affiliates for which it exercises significant influence without having a controlling interest (excluding oil and gas ventures in which Occidental holds an undivided interest) are accounted for under the equity method. Occidental reviews equity-method investments for impairment whenever events or changes in circumstances indicate that an other-than-temporary decline in value may have occurred. The amount of impairment, if any, is based on quoted market prices, when available, or other valuation techniques, including discounted cash flows. Occidental evaluates the facts and circumstances of any distributions in excess of its carrying amount in the investment to determine the appropriate accounting, including the source of the proceeds and any implicit or explicit commitments to fund the affiliate. If there is no implicit or explicit commitment the distribution is treated as a gain. If an implicit or explicit commitment exists to possibly fund the affiliate at a future date the distribution is recorded against the equity-method investment. See Note 4 - Investments and Related-Party Transactions for further discussion regarding investments in unconsolidated entities.

WES INVESTMENT

NON-CONTROLLING INTEREST

In 2023, Occidental and BlackRock formed a joint venture, for the continued development of the first commercial scale direct air capture facility using Carbon Engineering technology. The joint venture is a VIE and Occidental consolidates the VIE as it is the primary beneficiary. BlackRock’s investment is accounted for as a NCI. Each party has committed to make additional investments towards the completion of the direct air capture facility in Ector County, Texas, with BlackRock committed to invest up to $550 million. In addition, Occidental has entered into agreements with the joint venture related to project management, operations and maintenance and carbon removal offtake. Occidental may incur additional payments if certain construction and operational thresholds are not met.

Occidental may call the NCI on June 30, 2025 or earlier if the plant does not achieve commercial operations or ceases and permanently discontinues operations. Dividends from the joint venture will be distributed preferentially to the NCI up to a return threshold, then preferentially to Occidental thereafter. The NCI receives preferential distributions in liquidation.

Because distributions from the joint venture will not be consistent over time, or with the initial investments or ownership interest, Occidental has determined that the appropriate methodology for attributing income and loss from the joint venture is the HLBV method. Under the HLBV method, the amounts of income and loss attributed to the NCI in the consolidated statements of operations reflect changes in the amounts the NCI would hypothetically receive at each balance sheet date if


74			OXY 2023 FORM 10-K


						FINANCIAL STATEMENTS FOOTNOTES

the joint venture was liquidated. As of December 31, 2023, the VIE’s assets were comprised of $275 million construction in progress.

BERKSHIRE HATHAWAY OWNERSHIP

Berkshire Hathaway is a related party of Occidental due to its level of ownership of Occidental's common stock. As of December 31, 2023, Berkshire Hathaway’s ownership in Occidental included 244 million shares of common stock, 83.9 million of warrants of Occidental common stock with a strike price of $59.62, and $8.5 billion in preferred stock. Occidental has, from time to time, contracted with Berkshire Hathaway for the provision of electricity, rail and insurance. In addition, certain Berkshire Hathaway subsidiaries purchase various chemicals from OxyChem.

DISCONTINUED OPERATIONS

Unless otherwise indicated, information presented in the Notes to Consolidated Financial Statements relates only to Occidental's continuing operations. Information related to discontinued operations is included in Note 5 - Acquisitions, Divestitures and Other Transactions and in some instances, where appropriate, is included as a separate disclosure within the individual Notes to Consolidated Financial Statements.

RISKS AND UNCERTAINTIES

The process of preparing Consolidated Financial Statements in conformity with GAAP requires Occidental’s management to make informed estimates and judgments regarding certain types of financial statement balances and disclosures. Such estimates primarily relate to unsettled transactions and events as of the date of the Consolidated Financial Statements and judgments on expected outcomes as well as the materiality of transactions and balances. Changes in facts and circumstances or discovery of new information relating to such transactions and events may result in revised estimates and judgments and actual results may differ from estimates upon settlement. Management believes that these estimates and judgments provide a reasonable basis for the fair presentation of Occidental’s financial statements. Occidental establishes a valuation allowance against net operating losses and other deferred tax assets to the extent it believes the future benefit from these assets will not be realized in the statutory carryforward periods. Realization of deferred tax assets is dependent upon Occidental generating sufficient future taxable income and reversal of temporary differences in jurisdictions where such assets originate.

The accompanying Consolidated Financial Statements include assets of approximately $7.8 billion as of December 31, 2023 and net sales of approximately $4.4 billion in 2023, relating to Occidental’s operations in countries outside North America. Occidental has experienced and may continue to experience adverse consequences, such as risk of loss or production limitations, because certain of its international operations are located in countries affected by political instability, nationalizations, corruption, armed conflict, terrorism, insurgency, civil unrest, security problems, labor unrest, OPEC production restrictions, equipment import restrictions and sanctions. Exposure to such risks may increase if a greater percentage of Occidental’s future oil and gas production or revenue comes from international sources. Occidental attempts to conduct its affairs so as to mitigate its exposure to such risks and would seek compensation in the event of nationalization.

Because Occidental’s major products are commodities, significant changes in the prices of oil, NGL, natural gas and chemical products may have a significant impact on Occidental’s results of operations. Also, see Property, Plant and Equipment section below.

RECEIVABLES AND OTHER CURRENT ASSETS

Trade receivables, net of $3.2 billion and $4.3 billion as of December 31, 2023 and 2022, respectively, represent rights to payment for which Occidental had satisfied its obligations under a contract with a customer and its right to payment was conditioned only on the passage of time.

Other current assets includes amounts receivable from working interest partners in Occidental’s oil and gas operations, prepaid expenses, derivative assets and taxes receivable.

INVENTORIES

Materials and supplies are valued at weighted-average cost and are reviewed periodically for obsolescence. Oil, NGL and natural gas inventories are valued at the lower of cost or market.

For the chemical segment, Occidental’s finished goods inventories are valued at the lower of cost or market. For most of its domestic inventories, other than materials and supplies, the chemical segment uses the LIFO method as it better matches current costs and current revenue. For other countries, Occidental uses the first-in, first-out method (if the costs of goods are specifically identifiable) or the average-cost method (if the costs of goods are not specifically identifiable).

For assets acquired, PP&E cost is based on fair values at the acquisition date. AROs and interest costs incurred in connection with qualifying capital expenditures are capitalized and amortized over the lives of the related assets.

Occidental uses the successful efforts method to account for its oil and gas properties. Under this method, Occidental capitalizes costs of acquiring properties, costs of drilling successful exploration wells and development costs. The costs of exploratory wells are initially capitalized pending a determination of whether proved reserves have been found. If proved reserves have been found, the costs of exploratory wells remain capitalized. For exploratory wells that find reserves that cannot be classified as proved when drilling is completed, costs continue to be capitalized as suspended exploratory drilling costs if there have been sufficient reserves found to justify completion as a producing well and sufficient progress is being made in assessing the reserves and the economic and operating viability of the project. At the end of each quarter, management reviews the status of all suspended exploratory drilling costs in light of ongoing exploration activities, in particular, whether Occidental is making sufficient progress in its ongoing exploration and appraisal efforts or, in the case of discoveries requiring government sanctioning, analyzing whether development negotiations are underway and proceeding as planned. If management determines that future appraisal drilling or development activities are unlikely to occur, associated suspended exploratory well costs are expensed.

The following table summarizes the activity of capitalized exploratory well costs for continuing operations for the years ended December 31:


millions	2023		2022		2021
Balance — beginning of year	$	276	$	213	$	211
Additions to capitalized exploratory well costs pending the determination of proved reserves	750		323		163
Reclassifications to property, plant and equipment based on the determination of proved reserves	(314)		(183)		(67)
Capitalized exploratory well costs charged to expense	(307)		(77)		(94)
Balance — end of year	$	405	$	276	$	213

Occidental expenses annual lease rentals, the costs of injectants used in production and geological and geophysical costs as incurred.

Occidental determines depreciation and depletion of oil and gas producing properties by the unit-of-production method. It amortizes leasehold costs over total proved reserves and capitalized development and successful exploration costs over proved developed reserves.

Proved oil and gas reserves are those quantities of oil and gas which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible from a given date forward, from known reservoirs and under existing economic conditions, operating methods and government regulations prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. Proved reserves include PUD reserves. PUD reserves are supported by a management-approved, detailed, field-level development plan where sufficient capital has been committed to develop those reserves. Only PUD reserves which are reasonably certain to be drilled within five years of booking and are supported by a final investment decision to drill them are included in the development plan. A portion of the PUD reserves associated with international operations are expected to be developed beyond the five years and are tied to approved long-term development projects.

Occidental performs impairment tests with respect to its proved properties whenever events or circumstances indicate that the carrying value of property may not be recoverable. If there is an indication the carrying amount of the asset may not be recovered due to significant and prolonged declines in current and forward prices, significant changes in reserve estimates, changes in management’s plans, or other significant events, management will evaluate the property for impairment. Under the successful efforts method, if the sum of the undiscounted cash flows is less than the carrying value of the proved property, the carrying value is reduced to estimated fair value and reported as an impairment charge in the period. Individual proved properties are grouped for impairment purposes at the lowest level for which there are identifiable cash flows. The fair value of impaired assets is typically determined based on the present value of expected future cash flows using discount rates believed to be consistent with those used by market participants. The impairment test incorporates a number of assumptions involving expectations of future cash flows which can change significantly over time. These assumptions include estimates of future production, product prices, contractual prices, estimates of risk-adjusted oil and gas proved and unproved reserves and estimates of future operating and development costs. It is reasonably possible that prolonged declines in commodity prices, reduced capital spending in response to lower prices or increases in operating costs could result in additional impairments. See Note 9 - Fair Value Measurements and below for further discussion of asset impairments.


76			OXY 2023 FORM 10-K


						FINANCIAL STATEMENTS FOOTNOTES

Net capitalized costs attributable to unproved properties were $10.2 billion as of December 31, 2023 and $12.6 billion as of December 31, 2022. The unproved amounts are not subject to DD&A until they are classified as proved properties. Individually insignificant unproved properties are combined and amortized on a group basis based on factors such as geographic location, lease terms, success rates and other factors to provide for full amortization upon lease expiration or abandonment.

Significant unproved properties are assessed individually for impairment and when events or circumstances indicate that the carrying value of property may not be recovered a valuation allowance is provided if an impairment is indicated. Occidental periodically reviews significant unproved properties for impairments. When assessing for impairments, several factors are considered, including but not limited to, availability of funds for future exploration and development activities, current exploration and development plans, favorable or unfavorable exploration activity on the property or the adjacent property, geologists’ evaluation of the property, the current and projected political and regulatory climate, contractual conditions and the remaining lease term for the properties. If an impairment is indicated, Occidental will first determine whether a comparable transaction for similar properties or implied acreage valuation derived from domestic onshore market participants is available and will adjust the carrying amount of the unproved property to its fair value using the market approach. In situations where the market approach is not observable and unproved reserves are available, undiscounted future net cash flows used in the impairment analysis are determined based on managements’ risk adjusted estimates of unproved reserves, future commodity prices and future costs to produce the reserves. If undiscounted future net cash flows are less than the carrying value of the unproved property, the future net cash flows are discounted and compared to the carrying value for determining the amount of the impairment loss to record. Occidental utilizes the same assumptions and methodology discussed above for cash flows associated with proved properties.

CHEMICAL

Occidental’s chemical assets are depreciated using either the unit-of-production or the straight-line method, based upon the estimated useful lives of the facilities. The estimated useful lives of Occidental’s chemical assets, which range from three years to 50 years, are also used for impairment tests. The estimated useful lives for the chemical facilities are based on the assumption that Occidental will provide an appropriate level of annual expenditures to ensure productive capacity is sustained. Such expenditures consist of ongoing routine repairs and maintenance, as well as planned major maintenance activities. Ongoing routine repairs and maintenance expenditures are expensed as incurred. Planned major maintenance activities costs are capitalized and amortized over the period until the next planned overhaul. Additionally, Occidental incurs capital expenditures that extend the remaining useful lives of existing assets, increase their capacity or operating efficiency beyond the original specification or add value through modification for a different use. These capital expenditures are not considered in the initial determination of the useful lives of these assets at the time they are placed into service. The resulting revision, if any, of the asset’s estimated useful life is measured and accounted for prospectively.

Without these continued expenditures, the useful lives of these assets could decrease significantly. Other factors that could change the estimated useful lives of Occidental’s chemical assets include sustained higher or lower product prices, which are affected by domestic and international competition, demand, feedstock costs, energy prices, environmental regulations and technological changes.

Occidental performs impairment tests on its chemical assets whenever events or changes in circumstances lead to a reduction in the estimated useful lives or estimated future cash flows that would indicate that the carrying amount may not be recoverable, or when management’s plans change with respect to those assets. Any impairment loss would be calculated as the excess of the asset’s net book value over its estimated fair value.

MIDSTREAM AND MARKETING

Occidental’s midstream and marketing PP&E is depreciated over the estimated useful lives of the assets, using either the unit-of-production or straight-line method.

Occidental performs impairment tests on its midstream and marketing assets whenever events or changes in circumstances lead to a reduction in the estimated useful lives or estimated future cash flows that would indicate that the carrying amount may not be recoverable, or when management’s plans change with respect to those assets. Any impairment loss would be calculated as the excess of the asset’s net book value over its estimated fair value.

IMPAIRMENTS AND OTHER CHARGES

In 2023, Occidental recorded a pre-tax impairment of $180 million related to undeveloped acreage in the northern non-core area of the Powder River Basin where Occidental has decided not to pursue future exploration and appraisal activities. In 2023, impairment expense also included $29 million related to an equity method investment in Black Butte Coal Company.

During 2021, Occidental’s oil and gas segment recognized pre-tax impairment and related charges of $282 million primarily related to undeveloped leases that either expired or were set to expire in the near-term, where Occidental had no plans to pursue exploration activities and, to a lesser extent, impairments of oil and gas materials and supplies inventories.


OXY 2023 FORM 10-K			77


						FINANCIAL STATEMENTS FOOTNOTES

Prolonged declines in commodity prices, reduced capital spending in response to lower prices or increases in operating costs could result in additional impairments.

INTANGIBLES AND GOODWILL

As of December 31, 2023, Occidental had $960 million of other intangible assets primarily related to Carbon Engineering and TerraLithium, included in other long-term assets. These assets will be amortized between 9 and 25 years on a straight-line basis. Occidental performs impairment tests on its finite-lived intangible assets whenever events or changes in circumstances lead to a reduction in the estimated useful lives or estimated future cash flows that would indicate that the carrying amount may not be recoverable, or when management’s plans change with respect to those assets. Any impairment loss would be calculated as the excess of the asset’s net book value over its estimated fair value.

As of December 31, 2023, Occidental had $668 million of goodwill related to its ownership in Carbon Engineering, included in other long-term assets. Goodwill is subject to annual impairment testing every April. Occidental’s goodwill impairment test first assesses qualitative factors to determine whether goodwill is likely impaired. If the qualitative assessment indicates that it is more likely than not that the fair value of a reporting unit is less than its carrying amount including goodwill, Occidental will then perform a quantitative goodwill impairment test. Changes in goodwill may result from, among other things, impairments, future acquisitions, or future divestitures.

FAIR VALUE MEASUREMENTS

FAIR VALUES - RECURRING

Occidental primarily applies the market approach for recurring fair value measurements, maximizes its use of observable inputs and minimizes its use of unobservable inputs. Occidental utilizes the mid-point between bid and ask prices for valuing the majority of its assets and liabilities measured and reported at fair value. In addition to using market data, Occidental makes assumptions in valuing its assets and liabilities, including assumptions about the risks inherent in the inputs to the valuation technique. For assets and liabilities carried at fair value, Occidental measures fair value using the following methods:

■Occidental values exchange-cleared commodity derivatives using closing prices provided by the exchange as of the balance sheet date. These derivatives are classified as Level 1.

■OTC bilateral financial commodity contracts, foreign exchange contracts, interest rate swaps, warrants, options and physical commodity forward purchase and sale contracts are generally classified as Level 2 and are generally valued using quotations provided by brokers or industry-standard models that consider various inputs, including quoted forward prices for commodities, time value, volatility factors, credit risk and current market and contractual prices for the underlying instruments, as well as other relevant economic measures. Substantially all of these inputs are observable in the marketplace throughout the full term of the instrument, and can be derived from observable data or are supported by observable prices at which transactions are executed in the marketplace.

NON-FINANCIAL ASSETS

Occidental uses market-observable prices for assets when comparable transactions can be identified that are similar to the asset being valued. When Occidental is required to measure fair value and there is not a market-observable price for the asset or for a similar asset then the cost or income approach is used depending on the quality of information available to support management’s assumptions. The cost approach is based on management’s best estimate of the current asset replacement cost. The income approach is based on management’s best assumptions regarding expectations of future net cash flows. The expected cash flows are discounted using a commensurate risk-adjusted discount rate. Such evaluations involve significant judgment, and the results are based on expected future events or conditions such as sales prices, estimates of future oil and gas production or throughput, development and operating costs and the timing thereof, economic and regulatory climates and other factors, most of which are often outside of management’s control. However, assumptions used reflect a market participant’s view of long-term prices, costs and other factors and are consistent with assumptions used in Occidental’s business plans and investment decisions.

ACCRUED LIABILITIES - CURRENT

Accrued liabilities - current included accrued payroll, commissions and related expenses of $693 million and $582 million as of December 31, 2023 and 2022, respectively, and taxes other than on income of $618 million and $544 million as of December 31, 2023 and 2022, respectively. Dividends payable, also included in accrued liabilities - current, were $307 million and $289 million as of December 31, 2023 and 2022, respectively.

ENVIRONMENTAL LIABILITIES AND EXPENDITURES

Many factors could affect future remediation costs incurred by Occidental’s subsidiaries and result in adjustments to environmental remediation liabilities and the range of reasonably possible additional losses. The most significant are: (1) cost estimates for remedial activities may vary from the initial estimate; (2) the length of time, type or amount of remediation necessary to achieve the remedial objective may change due to factors such as site conditions, the ability to identify and control contaminant sources or the discovery of additional contamination; (3) a regulatory agency may ultimately reject or modify Occidental’s proposed remedial plan; (4) improved or alternative remediation technologies may change remediation costs; (5) laws and regulations may change remediation requirements or affect cost sharing or allocation of liability; and (6) changes in allocation or cost-sharing arrangements may occur.

Certain sites involve multiple parties with various cost-sharing arrangements, which fall into the following three categories: (1) environmental proceedings that result in a negotiated or prescribed allocation of remediation costs among the affected Occidental subsidiary and other alleged potentially responsible parties; (2) oil and gas ventures in which each participant pays its proportionate share of remediation costs reflecting its working interest; or (3) contractual arrangements, typically relating to purchases and sales of properties, in which the parties to the transaction agree to methods of allocating remediation costs. In these circumstances, the affected subsidiary evaluates the financial viability of other parties with whom it is alleged to be jointly liable, the degree of their commitment to participate and the consequences to such subsidiary of their failure to participate when estimating its ultimate share of liability. Occidental records its environmental remediation liabilities at its expected net cost of remedial activities and, based on these factors, believes that it will not be required to assume a share of liability of such other potentially responsible parties in an amount materially above amounts reserved.

In addition to the costs of investigations and clean-up measures, which often take in excess of 10 years at CERCLA NPL sites, Occidental’s environmental remediation liabilities include management’s estimates of the costs to operate and maintain remedial systems. If remedial systems are modified over time in response to significant changes in site-specific data, laws, regulations, technologies or engineering estimates, Occidental reviews and adjusts its environmental remediation liabilities accordingly.

ASSET RETIREMENT OBLIGATIONS

Occidental recognizes the fair value of AROs in the period in which a determination is made that a legal obligation exists to dismantle an asset and reclaim or remediate the property at the end of its useful life and the cost of the obligation can be reasonably estimated. The liability amounts are based on future retirement cost estimates and incorporate many assumptions such as time to abandonment, future inflation rates and the risk-adjusted discount rate. When the liability is initially recorded, Occidental capitalizes the cost by increasing the related PP&E balances. If the estimated future cost of the AROs changes, Occidental records an adjustment to both the AROs and PP&E. Over time, the liability is increased, expense is recognized for accretion and the capitalized cost is depreciated over the useful life of the asset.

The majority of Occidental’s AROs relate to the plugging of wells and the related abandonment of oil and gas properties.

At a certain number of its facilities, Occidental has identified conditional AROs that are related mainly to plant decommissioning. Occidental does not know or cannot estimate when it may settle these obligations. Therefore, Occidental cannot reasonably estimate the fair value of these liabilities. Occidental will recognize these conditional AROs in the periods in which sufficient information becomes available to reasonably estimate their fair values.

DERIVATIVE INSTRUMENTS

Derivatives are carried at fair value and on a net basis when a legal right of offset exists with the same counterparty. Occidental applies hedge accounting when transactions meet specified criteria for cash flow hedge treatment and management elects and documents such treatment. Otherwise, any fair value gains or losses are recognized in earnings in the current period. For cash flow hedges, the gain or loss on the effective portion of the derivative is reported as a component of OCI with an offsetting adjustment to the carrying value of the item being hedged. Realized gains or losses from cash flow hedges, and any ineffective portion, are recorded as a component of net sales in the Consolidated Statements of Operations. Ineffectiveness is primarily created by a lack of correlation between the hedged item and the hedging instrument due to location, quality, grade or changes in the expected quantity of the hedged item. Gains and losses from derivative instruments are reported net in the Consolidated Statements of Operations. See Note 8 Derivatives. There were no fair value hedges as of and during the years ended December 31, 2023, 2022 and 2021.

STOCK-BASED INCENTIVE PLANS

Occidental has established the Plans that are more fully described in Note 15 - Stock-Based Incentive Plans. A summary of Occidental’s accounting policy for awards issued under the Plans is as follows.

For cash- and stock-settled RSUs and CROCEI awards, compensation value is initially measured on the grant date using the quoted market price of Occidental’s common stock and the estimated payout on the grant date. The fair value of stock options is estimated using a Black Scholes model. For TSRI awards, compensation value is initially measured on the grant date using the fair value derived from a Monte Carlo valuation model. Compensation expense for all awards is recognized on a straight-line basis over the requisite service periods, which is generally over the awards’ respective vesting or performance periods. The stock-settled awards are expensed using the initially measured compensation value. The liability resulting from cash settled awards and accrued dividends are remeasured at each reporting period. Dividends accrued on unvested awards are adjusted quarterly for any changes in the number of share equivalents expected to be paid based on the relevant performance and market criteria, if applicable.

RETIREMENT AND POSTRETIREMENT BENEFIT PLANS

Occidental recognizes the overfunded or underfunded amounts of its defined benefit pension and postretirement plans, which are more fully described in Note 11 - Retirement and Postretirement Benefit Plans, in its financial statements using a December 31 measurement date.

Occidental’s defined benefit pension and postretirement benefit plan obligations are actuarially determined based on various assumptions and discount rates. The discount rate assumptions used are meant to reflect the interest rate at which the obligations could effectively be settled on the measurement date. Occidental estimates the rate of return on assets with regard to current market factors but within the context of historical returns. Occidental funds and expenses negotiated pension increases for domestic union employees over the terms of the applicable collective bargaining agreements.

Pension and any postretirement plan assets are measured at fair value. Common stock, preferred stock, publicly registered mutual funds, U.S. government securities and corporate bonds are valued using quoted market prices in active markets when available. When quoted market prices are not available, these investments are valued using pricing models with observable inputs from both active and non-active markets. Common and collective trusts are valued at the fund units’ NAV provided by the issuer, which represents the quoted price in a non-active market. Short-term investment funds are valued at the fund units’ NAV provided by the issuer.

Occidental swapped oil and gas acreage with a fair value of approximately $120 million and $340 million in non-monetary exchange transactions during the years ended December 31, 2023 and December 31, 2022, respectively.

CASH EQUIVALENTS AND RESTRICTED CASH EQUIVALENTS

Occidental considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents or restricted cash equivalents. The cash equivalents and restricted cash equivalents balance as of December 31, 2023, included investments in government money market funds in which the carrying value approximates fair value.

The following table provides a reconciliation of cash, cash equivalents, restricted cash and restricted cash equivalents as reported at the end of the period in the Consolidated Statements of Cash Flows for the year ended December 31, 2023 and 2022:

FOREIGN CURRENCY TRANSACTIONS

The functional currency applicable to all of Occidental’s international oil and gas operations is the U.S. dollar since cash flows are denominated principally in U.S. dollars. In Occidental’s other operations, Occidental’s use of non-United States dollar functional currencies was not material for all years presented. The effect of exchange rates on transactions in foreign currencies is included in periodic income. Occidental reports the exchange rate differences arising from translating foreign-currency-denominated balance sheet accounts to the United States dollar as of the reporting date in OCI. Exchange-rate gains and losses for continuing operations were not material for all years presented.

INCOME TAXES

Occidental files various U.S. federal, state and foreign income tax returns. The impact of changes in tax regulations are reflected when enacted. In general, deferred federal, state and foreign income taxes are provided on temporary differences between the financial statement carrying amounts of assets and liabilities and their respective tax basis. Occidental routinely assesses the realizability of its deferred tax assets. If Occidental concludes that it is more likely than not that some of the deferred tax assets will not be realized, the tax asset is reduced by a valuation allowance. Occidental recognizes a tax benefit from an uncertain tax position when it is more likely than not that the position will be sustained upon examination, based on the technical merits of the position. The tax benefit recorded is equal to the largest amount that is greater than 50% likely to be realized through final settlement with a taxing authority. Interest and penalties related to unrecognized tax benefits are recognized in income tax expense (benefit). See Note 10 - Income Taxes for more information.

LOSS CONTINGENCIES

Occidental or certain of its subsidiaries are involved, in the normal course of business, in lawsuits, claims and other legal proceedings that seek, among other things, compensation for alleged personal injury, breach of contract, property damage or other losses, punitive damages, civil penalties, or injunctive or declaratory relief. Occidental or certain of its subsidiaries also are involved in proceedings under CERCLA and similar federal, state, local and international environmental laws. These environmental proceedings seek funding or performance of remediation and, in some cases, compensation for alleged property damage, punitive damages, civil penalties, injunctive relief, and government oversight costs. Usually Occidental or such subsidiaries are among many companies in these environmental proceedings and have to date been successful in sharing response costs with other financially sound companies. Further, some lawsuits, claims and legal


OXY 2023 FORM 10-K			81


						FINANCIAL STATEMENTS FOOTNOTES

proceedings involve acquired or disposed assets with respect to which a third party or Occidental or its subsidiaries retains liability or indemnifies the other party for conditions that existed prior to the transaction.

In accordance with applicable accounting guidance, Occidental accrues reserves for outstanding lawsuits, claims and proceedings when it is probable that a liability has been incurred and the liability can be reasonably estimated. In Note 12 - Environmental Liabilities and Expenditures, Occidental has disclosed its reserve balances for environmental remediation matters that satisfy this criteria. See Note 13 - Lawsuits, Claims, Commitments and Contingencies.

RECENT ACCOUNTING PRONOUNCEMENTS

In December 2023, FASB issued new guidance to improve Income Tax disclosures to provide information to assess how an entity’s operations and related tax risks and tax planning and operational opportunities affect its tax rate and prospects for future cash flows. The rules become effective for annual periods beginning after December 15, 2024. The standard modifies required income tax disclosures. Occidental is currently evaluating the impact of adopting this guidance on the consolidated financial statements.

In November 2023, FASB issued new guidance to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The rules become effective for the fiscal years beginning after December 15, 2023. The standard requires additional disclosures about operating segments. Occidental is currently evaluating the impact of adopting this guidance on the consolidated financial statements.

In August 2023, FASB issued new guidance to provide specific guidance on how a joint venture, upon formation, should recognize and initially measure assets contributed and liabilities assumed. The rules become effective prospectively for all joint venture formations occurring on or after January 1, 2025. Occidental is currently assessing the impact of this guidance.


NOTE 2 - REVENUE

Revenue from customers is recognized when obligations under the terms of a contract are satisfied; this generally occurs with the delivery of oil, NGL, gas, chemicals or services such as transportation. Revenue from customers is measured as the amount of consideration Occidental expects to receive in exchange for the delivery of goods or services. Contracts may last from one month to one year or more and may have renewal terms that extend indefinitely at the option of either party. Price is typically based on market indexes. Volumes fluctuate due to production and, in certain cases, customer demand and transportation availability. Occidental records revenue net of certain taxes, such as sales taxes, that are assessed by government authorities on Occidental’s customers.

Occidental does not incur significant costs to obtain contracts. Incidental items that are immaterial in the context of the contract are recognized as expenses. Sales of hydrocarbons and chemicals to customers are invoiced and settled on a monthly basis. Occidental is not usually subject to obligations for warranties, rebates, returns or refunds except in the case of customer incentive payments as discussed for the chemical segment below. Occidental does not typically receive payment in advance of satisfying its obligations under the terms of its sales contracts with customers; therefore, liabilities related to such payment are immaterial to Occidental. Occidental does not disclose consideration for remaining performance obligations with an original expected duration of one year or less or for variable consideration related to unsatisfied performance obligations.

OIL AND GAS SEGMENT

Revenue from oil and gas production is recognized when production is delivered and control passes to the customer. Revenues from the production of oil and gas properties in which Occidental has an interest with other producers are recognized on the basis of Occidental’s net revenue interest.

CHEMICAL SEGMENT

Revenue from chemical product sales is recognized when control passes to the customer. Certain incentive programs may provide for payments or credits to be made to customers based on the volume of product purchased over a defined period. Customer incentives are estimated and recorded as a reduction to revenue ratably over the contract period. Such estimates are evaluated and revised as warranted. Revenue from exchange contracts is excluded from revenue from customers.

MIDSTREAM AND MARKETING SEGMENT

Revenue from pipeline and gas processing is recognized upon the completion of the transportation or processing service. Revenue from power sales is recognized upon delivery. Net marketing revenue is recognized upon completion of contract terms that are a prerequisite to payment and upon title transfer for physical deliveries. Unless the normal purchases and sales exception has been elected, net marketing revenue is classified as a derivative, reported on a net basis, recorded at fair value. Changes in fair value are reflected in net sales and excluded from revenue from customers in the table below.

						FINANCIAL STATEMENTS FOOTNOTES

In September 2023, Occidental sold certain non-core proved and unproved properties in the Permian Basin for $202 million and recorded a gain on sale of assets of $142 million.

Throughout 2023, Occidental entered into non-monetary exchange agreements, primarily in the Permian Basin. These exchanges were recorded as acquisitions and divestitures at a total combined fair value of $120 million. The difference in the assets' net book value was treated as a recovery of cost and normal retirement, which resulted in no gain or loss being recognized.

In August 2023, Occidental entered into an agreement with Carbon Engineering Ltd., its equity method investee, to purchase the remaining 68% interest not already owned by Occidental or its affiliates for total cash consideration of approximately $1.1 billion, resulting in Carbon Engineering becoming a wholly owned subsidiary of Occidental. The transaction qualifies as a business combination and is accounted for using the acquisition method of accounting. Because Occidental acquired control of Carbon Engineering in the 2023 purchase, Occidental remeasured its previously held 32% equity interest at its acquisition-date fair value and recognized the resulting gain of $283 million in accordance with GAAP. The purchase price will be made in three approximately equal annual payments, with the first payment made at closing. This transaction closed on November 3, 2023, and Occidental made the first payment of $349 million. The remaining two payments will be paid on the first and second anniversaries of closing, which were accrued on the closing date. With this purchase Occidental intends to accelerate technological innovation and cost reductions in Carbon Engineering's direct air capture technology. Carbon Engineering’s current and historical results of operations are immaterial to Occidental.

The purchase price was allocated to the major categories of assets and liabilities acquired based upon their estimated fair values at the date of acquisition. The valuation of intangible assets is based on inputs that are not observable in the market and thus represent Level 3 inputs. The fair value of intangible assets was derived using an income approach, with significant inputs being forecasted revenues and expenses, an anticipated growth rate, and an estimated discount rate.

Occidental allocated the preliminary purchase price to the fair value of Carbon Engineering’s assets as follows:


millions	2023
Fair value of assets acquired:
Cash and other current assets	$	154
Property, plant and equipment	11
Intangible assets related to developed technology	845
Goodwill	668
Total fair value of assets acquired	$	1,678
Fair value of liabilities acquired:
Liabilities acquired	110
Deferred tax liability	190
Total liabilities assumed	$	300

Fair value of previously held interest	371

Total acquisition consideration	$	1,007

2022

Throughout 2022, Occidental entered into non-monetary exchange agreements, primarily in the Permian Basin. These exchanges were recorded as acquisitions and divestitures at a total combined fair value of $340 million.

In 2022, Occidental acquired additional interests in emerging low-carbon businesses to advance net-zero pathway for a combined net purchase price of approximately $350 million.

In November 2022 and December 2022, Occidental acquired additional primarily producing assets in the Permian Basin for a combined net purchase price of approximately $400 million.

In November 2021, Occidental entered into an agreement to sell certain non-strategic assets in the Permian Basin. The transaction closed in January 2022 for net cash proceeds of approximately $190 million. The difference in the proved assets' net book value and adjusted purchase price was treated as a normal retirement, which resulted in no gain or loss being recognized. The difference in the unproved assets' net book value and adjusted purchase price resulted in a gain on sale of approximately $123 million. The gain has been presented within gains on sales of assets and equity investments, net in the Consolidated Statements of Operations.

In 2022, Occidental sold 10.0 million limited partner units of WES for proceeds of approximately $250 million, resulting in a gain of $62 million, see Note 4 - Investments and Related-Party Transactions.

2021

In November 2021, Occidental acquired additional working interests in certain assets in the Permian EOR business for a net purchase price of approximately $285 million.

In October 2021, Occidental closed the sale of its Ghana assets. See below discussion on Discontinued Operations for additional information. This divestiture completed Occidental's large-scale asset divestiture program.

In June 2021, Occidental entered into an agreement to sell certain non-strategic assets in the Permian Basin. The transaction closed in July 2021 for net cash proceeds of approximately $475 million. The difference in the assets' net book value and adjusted purchase price was treated as a recovery of cost and normal retirement, which resulted in no gain or loss being recognized.

In March 2021, Occidental completed the sale of certain non-operated assets in the DJ Basin for net cash proceeds of approximately $280 million. The difference in the assets' net book value and adjusted purchase price was treated as a recovery of cost and normal retirement, which resulted in no gain or loss being recognized.

In 2021, Occidental sold 14 million limited partner units of WES for proceeds of approximately $250 million, see Note 4 - Investments and Related-Party Transactions.

DISCONTINUED OPERATIONS

In 2021, Occidental recorded a $437 million after-tax loss contingency in discontinued operations associated with its former operations in Ecuador, see Note 13 - Lawsuits, Claims, Commitments and Contingencies.

In October 2021, Occidental closed the sale of its Ghana assets for $750 million and net proceeds of $555 million, after closing adjustments to reflect an April 1, 2021 effective date. In addition, Occidental settled certain tax claims related to historical operations in Ghana for $170 million. Prior to the sale, 2021 operations in Ghana resulted in an after-tax loss of $31 million.

DEBT MATURITIES

As of December 31, 2023, future principal payments of debt were less than $18.0 billion, of which $1.1 billion is due in 2024, $1.2 billion in 2025, $1.4 billion in 2026, $0.9 billion in 2027, and $13.3 billion due in 2028 and thereafter.

ZERO COUPONS

The Zero Coupons have an aggregate principal amount due at the 2036 maturity of approximately $673 million. The Zero Coupons can be put to Occidental in October of each year, in whole or in part, for the then-accreted value of the outstanding Zero Coupons. The Zero Coupons can next be put to Occidental in October 2024, which, if put in whole, would be $362 million at such date. Occidental currently has the ability to meet this obligation and may use available capacity under the RCF to satisfy the put should it be exercised.

FAIR VALUE OF DEBT

Occidental estimates the fair value of fixed-rate debt based on the quoted market prices for those instruments or on quoted market yields for similarly rated debt instruments, taking into account such instruments’ maturities. The estimated fair values of Occidental’s debt as of December 31, 2023, and 2022, the majority of which were classified as Level 1, were approximately $18.1 billion and $17.6 billion, respectively. Occidental’s exposure to changes in interest rates relates primarily to its variable-rate, long-term debt obligations, and is not material. As of December 31, 2023, and 2022, variable-rate debt constituted approximately 0.4% of Occidental’s total debt.

DEBT RATINGS

As of December 31, 2023, Occidental’s long-term debt was rated Baa3 by Moody’s Investors Service, BBB- by Fitch Ratings and BB+ by Standard and Poor’s. Occidental's credit rating was upgraded to investment grade by Moody's Investors Service in March 2023 and by Fitch Ratings in May 2023. Any downgrade in credit ratings could impact Occidental's ability to access capital markets and increase its cost of capital. In addition, Occidental or its subsidiaries may be requested, elect to provide or in some cases be required to provide collateral in the form of cash, letters of credit, surety bonds or other acceptable support as financial assurance of their performance and payment obligations under certain contractual arrangements such as pipeline transportation contracts, environmental remediation obligations, oil and gas purchase contracts and certain derivative instruments.

As of the date of this filing, Occidental had provided required financial assurances through a combination of cash, letters of credit and surety bonds and had not issued any letters of credit under the RCF or other committed facilities. For additional information, see Risk Factors in Part I, Item IA of this Form 10-K.

CROWNROCK ACQUISITION FINANCING

In connection with the CrownRock Acquisition, Occidental has secured a fully-committed $5.3 billion bridge loan facility, a $2.0 billion 364-day term loan, and a $2.7 billion two-year term loan. No amounts were drawn as of December 31, 2023 under any acquisition financing. Proceeds from the loans must be used to fund all or a portion of the CrownRock Acquisition.

REVOLVING CREDIT FACILITY

In December 2021, Occidental entered into the Second Amended and Restated Credit Agreement in which the total committed borrowing capacity of $4.0 billion is based on a SOFR benchmark. The interest rate margin and the facility fee rates are subject to adjustments based on Occidental’s performance on specified sustainability target thresholds with respect to absolute reductions in GHG emissions from its worldwide operated assets. The RCF maturity date is June 30, 2025. In February 2024, Occidental entered into a Third Amended and Restated Credit Agreement with the same committed borrowing capacity as above, but extended the maturity date to June 30, 2028. No amounts were drawn under the facility as of December 31, 2023.


90			OXY 2023 FORM 10-K


						FINANCIAL STATEMENTS FOOTNOTES

Borrowings under the RCF bear interest at SOFR benchmark rates, plus a margin based on Occidental’s senior debt ratings. The facility has similar terms to other debt agreements and does not contain material adverse change clauses or debt ratings triggers that could restrict Occidental’s ability to borrow, or that would permit lenders to terminate their commitments or accelerate debt repayment. The facility provides for the termination of loan commitments and requires immediate repayment of any outstanding amounts if certain events of default occur. As of the date of this filing, Occidental had no drawn amounts under the RCF. In 2023, Occidental paid average annual facility fees of 0.22% on the total commitment amount.

RECEIVABLES SECURITIZATION FACILITY

In December 2021, Occidental amended and extended its existing receivables securitization facility to December 2024. In February 2023, Occidental amended the facility to expand its available borrowing capacity to $600 million. As of December 31, 2023, the facility had $600 million of available borrowing capacity and no drawn amounts. The amended facility includes adjustments based on the same specified sustainability target thresholds as contained in the RCF.


NOTE 7 - LEASE COMMITMENTS

Occidental identifies leases through its accounts payable and contract monitoring processes. Lease assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. Lease assets include the discounted value of future lease payments, upfront payments and costs incurred to execute the lease and are amortized on a straight-line basis over the lease term. Occidental assesses the likelihood of exercising renewal, termination and purchase options to determine the lease term. Occidental uses its incremental borrowing rate at commencement date to determine the present value of lease payments. The incremental borrowing rate is the rate of interest that Occidental would pay to borrow an amount equal to the lease payments over a similar term on a collateralized basis in a similar economic environment. For assets except drilling rigs, Occidental does not separate lease and non-lease components as the non-lease portions were not significant.

Occidental has operating leases for oil and gas exploration and development equipment, including offshore and onshore drilling rigs of $385 million, office space of $339 million, compressors of $125 million, railcars of $112 million, marine transportation vessels of $110 million and $45 million consisting of storage facilities and other field equipment. Operating leases also include easements and real estate of $57 million. These operating leases have contract expiration terms ranging from one to 10 years.

Occidental’s finance leases include compressors of $454 million, office space of $255 million, and $28 million of other assets. Property, plant and equipment included $738 million of finance leases at December 31, 2023.

The following summarizes maturities of lease liabilities at December 31, 2023:

NOTE 8 - DERIVATIVES

OBJECTIVE AND STRATEGY

Occidental uses a variety of derivative financial instruments and physical contracts to manage its exposure to commodity price fluctuations, transportation commitments and to fix margins on the future sale of stored commodity volumes. Occidental also enters into derivative financial instruments for trading purposes. Derivatives are carried at fair value and on a net basis when a legal right of offset exists with the same counterparty.

Occidental may elect normal purchases and normal sales exclusions when physically delivered commodities are purchased or sold to a customer. Occidental occasionally applies cash flow hedge accounting treatment to derivative financial instruments to lock in margins on the forecasted sales of its natural gas storage volumes. The value of cash flow hedges was insignificant for all periods presented. See Note 1 - Summary of Significant Accounting Policies for Occidental’s accounting policy on derivatives.

DERIVATIVES NOT DESIGNATED AS HEDGING INSTRUMENTS

As of December 31, 2023, Occidental’s derivatives not designated as hedges consisted of marketing derivatives. All interest rate swaps were settled prior to December 31, 2022.

Derivative instruments that are not designated as hedging instruments are required to be recorded on the balance sheet at fair value. Changes in fair value will impact Occidental’s earnings through mark-to-market adjustments until the physical commodity is delivered or the financial instrument is settled.

MARKETING DERIVATIVES

Occidental’s marketing derivative instruments not designated as hedges are short-duration physical and financial forward contracts. A substantial majority of Occidental’s physically settled derivative contracts are index-based and carry no mark-to-market valuation in earnings. As of December 31, 2023, the weighted-average settlement price of these forward contracts was $76.36/Bbl and $2.62/Mcf for crude oil and natural gas, respectively. The weighted-average settlement price was $81.37/Bbl and $7.89/Mcf for crude oil and natural gas, respectively, as of December 31, 2022. Net gains and losses associated with marketing derivative instruments not designated as hedging instruments are recognized currently in net sales. Derivative settlements and collateralization are classified as cash flows from operating activities unless the derivatives contain an other-than-insignificant financing element, in which case the settlements and collateralization are classified as cash flows from financing activities.

The following table summarizes net short volumes associated with the outstanding marketing commodity derivatives not designated as hedging instruments as of December 31:



	2023	2022
Oil commodity contracts
Volume (MMbbl)	(20)	(33)

Natural gas commodity contracts
Volume (Bcf)	(113)	(112)

INTEREST RATE SWAPS

Occidental retired all remaining outstanding interest rate swaps in 2022. Occidental's interest rate swap contracts locked in a fixed interest rate in exchange for a floating interest rate indexed to the three-month London Interbank Offered Rate throughout the reference period. Interest rate swaps and collateralization are classified as cash flows from financing activities.

FAIR VALUE OF DERIVATIVES

Occidental has categorized its assets and liabilities that are measured at fair value in a three-level fair value hierarchy, based on the inputs to the valuation techniques: Level 1 – using quoted prices in active markets for the assets or liabilities; Level 2 – using observable inputs other than quoted prices for the assets or liabilities; and Level 3 – using unobservable inputs. Transfers between levels, if any, are reported at the end of each reporting period. The following table presents the fair values of Occidental’s outstanding derivatives. Fair values are presented at gross amounts below, including when derivatives are subject to netting arrangements, and are presented on a net basis in the Consolidated Balance Sheets.

CREDIT RISK

The majority of Occidental’s counterparty credit risk is related to the physical delivery of energy commodities to its customers and their inability to meet their settlement commitments. Occidental manages credit risk by selecting counterparties that it believes to be financially strong, by entering into netting arrangements with counterparties and by requiring collateral or other credit risk mitigants, as appropriate. Occidental actively evaluates the creditworthiness of its counterparties, assigns appropriate credit limits and monitors credit exposures against those assigned limits. Occidental also enters into futures contracts through regulated exchanges with select clearinghouses and brokers, which are subject to minimal credit risk, if any.

NOTE 9 - FAIR VALUE MEASUREMENTS

FAIR VALUES – NONRECURRING

In 2023, Occidental recorded a pre-tax impairment of $180 million related to undeveloped acreage in the northern non-core area of the Powder River Basin where Occidental has decided not to pursue future exploration and appraisal activities. Impairment expense also included a $29 million impairment related to an equity method investment in Black Butte Coal Company.

There were no significant non-recurring fair value measurements in 2022.

In 2021, Occidental recorded pre-tax impairments of $276 million related to undeveloped leases that either expired or were set to expire in the near-term, where Occidental had no plans to pursue exploration activities.

FINANCIAL INSTRUMENTS FAIR VALUE

The carrying amounts of cash, cash equivalents, restricted cash, restricted cash equivalents and other financial instruments, other than fixed-rate debt, approximate fair value. See Note 6 - Long-Term Debt for the fair value of long-term debt.


NOTE 10 - INCOME TAXES

LEGAL ENTITY REORGANIZATION

To align Occidental’s legal entity structure with the nature of its business activities after completing the acquisition of Anadarko and subsequent large scale post-acquisition divestiture programs, management undertook a legal entity reorganization that was completed in 2022.

INFLATION REDUCTION ACT

PILLAR TWO

Approximately 140 countries have agreed to a statement in support of the OECD Pillar Two initiative that proposes a 15% global minimum tax on a jurisdiction by jurisdiction basis. A number of countries, including European Union member states, the United Kingdom, and Canada have enacted or are expected to enact legislation to be effective as early as 2024, with widespread implementation of a global minimum tax expected by 2025. As the legislation becomes effective in countries in which Oxy operates, the company’s cash tax could increase and its effective tax rate could be negatively impacted. Occidental will continue to monitor proposed legislation and guidance issued by both the OECD as well as the jurisdictions in which it operates to assess the impact on the its tax position.

The following reconciliation of the U.S federal statutory income tax rate to Occidental’s worldwide effective tax rate on income from continuing operations for the years ended December 31 is stated as a percentage of income from continuing operations before income taxes:

Worldwide effective tax rate	27	%	6	%	25	%

In 2023, Occidental’s worldwide effective tax rate of 27% was higher than the U.S. statutory rate of 21% and primarily driven by Occidental's jurisdictional mix of income, where international income is subject to tax at statutory rates as high as 55%.

In 2022, Occidental’s worldwide effective tax rate was 6%, which was lower than the U.S. statutory rate of 21% and primarily driven by a tax benefit associated with Occidental's legal entity reorganization, as described above, partially offset by higher tax rates in the foreign jurisdictions in which Occidental operates.

In 2021, Occidental’s worldwide effective tax rate was 25%, which was higher than the U.S. statutory rate of 21% due to higher tax rates in the foreign jurisdictions in which Occidental operates, partially offset by the tax impact of business credits, state tax revaluations and other domestic tax benefits.

Total deferred tax assets, after valuation allowances, were $2.0 billion and $2.2 billion as of December 31, 2023 and 2022, respectively. Occidental expects to realize the recorded deferred tax assets, net of any allowances, through future operating income and reversal of temporary differences. The total deferred tax liabilities were $7.7 billion as of December 31, 2023 and 2022.

As of December 31, 2023, Occidental had foreign tax credit carryforwards of $2.8 billion and state tax credit carryforwards of $33 million. Occidental had recorded a valuation allowance for $2.8 billion of the foreign tax credit carryforwards and $29 million of the state tax credit carryforwards.

As of December 31, 2023, Occidental had tax-effected foreign net operating loss carryforwards of $854 million, state net operating loss carryforwards of $199 million, and federal net operating loss carryforwards of $3 million. The carryforward balances have varying carryforward periods through 2043, excluding certain attributes for which there is an indefinite carryforward period. A valuation allowance was recorded for $801 million of the tax-effected foreign net operating loss carryforwards and $159 million of the tax-effected state net operating loss carryforwards. Occidental had an additional valuation allowance of $145 million against other foreign deferred tax assets.

Occidental had a tax-effected state interest expense carryforward of $11 million with a valuation allowance for $3 million of the state interest expense carryforward as of December 31, 2023.

A deferred tax liability had not been recognized for temporary differences related to unremitted earnings of certain consolidated international subsidiaries aggregating approximately $984 million as of December 31, 2023, as it is Occidental’s intention to reinvest such earnings indefinitely. If the earnings of these international subsidiaries were not indefinitely reinvested, an additional deferred tax liability of approximately $232 million would be required.

The December 31, 2023 balance of unrecognized tax benefits of $2.0 billion included potential benefits of $2.0 billion of which, if recognized, $1.5 billion would affect the effective tax rate on income. Also included were benefits of $45 million related to tax positions for which the ultimate deductibility is highly certain, but the timing of such deductibility is uncertain. Unrecognized tax benefits are included in deferred credits and other liabilities - other. Occidental records estimated potential interest and penalties related to liabilities for unrecognized tax benefits in the provisions for domestic and foreign income taxes. In 2023, Occidental recorded interest related to liabilities for unrecognized tax benefits of $159 million, for a cumulative accrued interest related to liabilities for unrecognized tax benefits of $576 million as of December 31, 2023. There were no penalties associated with liabilities for unrecognized tax benefits recorded for the years ended December 31, 2023 and 2022. Over the next 12 months, it is reasonably possible that the total amount of unrecognized tax benefits could decrease by an estimated $10 million due to settlements with taxing authorities or lapses in statutes of limitation.

Occidental recognized $79 million and $280 million in federal and state income tax receivables as of December 31, 2023 and 2022, respectively, which was recorded in other current assets. In addition, Occidental recognized $31 million and $33 million in 2023 and 2022, respectively, of long-term income tax receivables, which were recorded in long-term receivables and other assets, net.

Occidental is subject to audit by various tax authorities in varying periods. See Note 13 - Lawsuits, Claims, Commitments and Contingencies for a discussion of these matters.


NOTE 11 - RETIREMENT AND POSTRETIREMENT BENEFIT PLANS

Occidental has various defined contribution and defined benefit plans for its salaried, domestic union and nonunion hourly and certain foreign national employees. In addition, Occidental also provides medical and other benefits for certain active, retired and disabled employees and their eligible dependents.

DEFINED CONTRIBUTION PLANS

All domestic employees and certain foreign national employees are eligible to participate in one or more of the defined contribution retirement or savings plans that provide for periodic contributions by Occidental based on plan-specific criteria, such as base pay, level and employee contributions. Certain salaried employees participate in a supplemental retirement plan that restores benefits lost due to government limitations on qualified retirement benefits. The accrued liabilities for the supplemental retirement plan were $330 million and $288 million as of December 31, 2023 and 2022, respectively. In 2023, 2022 and 2021 Occidental expensed $221 million, $202 million and $166 million, respectively under the provisions of these defined contribution and supplemental retirement plans.

DEFINED BENEFIT PLANS

Participation in defined benefit plans is limited. Approximately 300 domestic and 300 foreign national employees, mainly union, nonunion hourly and certain employees that joined Occidental from acquired operations with grandfathered benefits, are currently accruing benefits under these plans.

Pension costs for Occidental’s defined benefit pension plans, determined by independent actuarial valuations, are generally funded by payments to trust funds, which are administered by independent trustees.

POSTRETIREMENT AND OTHER BENEFIT PLANS

Occidental provides medical and dental benefits and life insurance coverage for certain active, retired and disabled employees and their eligible dependents. Occidental generally funds the benefits as they are paid during the year. In 2023, 2022 and 2021, these benefit costs, including the postretirement costs, were $175 million, $211 million and $211 million, respectively.

ADDITIONAL INFORMATION

The following table sets forth the weighted-average assumptions used to determine Occidental’s benefit obligation and net periodic benefit cost for domestic plans for the years ended December 31:


	Pension Benefits				Postretirement Benefits
	2023		2022		2023		2022
Benefit Obligation Assumptions:

Rate of increase in compensation levels	3.95	%	3.98	%	—		—
Assumed long-term rate of return on assets	6.65	%	4.36	%	—		—

For domestic pension plans and postretirement benefit plans, Occidental based the discount rate on a AA-AAA Universe yield curve in 2023 and 2022. The assumed long-term rate of return on assets is estimated with regard to current market factors but within the context of historical returns for the asset mix that exists at year end. Assumed rates of compensation increases for active participants in certain plans vary by age group.

In 2021, Occidental adopted the Society of Actuaries Pri-2012 Private Retirement Plans Mortality Tables with MP-2021 Mortality Improvement Scale, which updated the mortality assumptions that private defined-benefit plans in the United States use in the actuarial valuations that determine a plan sponsor’s pension obligations. These mortality assumptions reflect additional data that the Social Security Administration released since the previous mortality tables and improvement scales were released.


100			OXY 2023 FORM 10-K


						FINANCIAL STATEMENTS FOOTNOTES

The postretirement benefit obligation was determined by application of the terms of medical and dental benefits and life insurance coverage, including the effect of established maximums on covered costs, together with relevant actuarial assumptions and health care cost trend rates. Health care cost trend rates for Medicare advantaged prescription drug plans are 8.7% starting in 2023, then grading down to 4.5% in 2028 and beyond. Health care cost trend rates used for non-medicare advantaged prescription drug plans are 5.8% to 6.3% in 2023, then grading down to 4.5% in 2028 and beyond.

The actuarial assumptions used could change in the near-term as a result of changes in expected future trends and other factors that, depending on the nature of the changes, could cause increases or decreases in the plan assets and liabilities.

FAIR VALUE OF PENSION PLAN ASSETS

Qualified defined benefit plan assets are monitored by Occidental’s Pension and Retirement Trust and Investment Committee in its role as a fiduciary. The Investment Committee selects and employs various external professional investment management firms to manage specific investments across the spectrum of asset classes. The Investment Committee employs a liability driven investment approach that uses a diversified blend of investments (equity securities, fixed-income securities, and alternative investments) along a glide path to optimize the long-term return of plan assets relative to plan liabilities, at a prudent level of risk. Equity investments are diversified across U.S. and non-U.S. stocks, as well as differing styles and market capitalizations. Investment performance is measured and monitored on an ongoing basis through quarterly investment portfolio and manager guideline compliance reviews, annual liability measurements and periodic studies.

The fair values of Occidental’s pension plan assets by asset category were as follows:

The laws that require or address environmental remediation, including CERCLA and similar federal, state, local and international laws, may apply retroactively and regardless of fault, the legality of the original activities or the current ownership or control of sites. Occidental or certain of its subsidiaries participate in or actively monitor a range of remedial activities and government or private proceedings under these laws with respect to alleged past practices at Third-Party, Currently Operated, and Closed or Non-operated Sites, which categories may include NPL Sites. Remedial activities may include one or more of the following: investigation involving sampling, modeling, risk assessment or monitoring; clean-up measures including removal, treatment or disposal; or operation and maintenance of remedial systems. The environmental proceedings seek funding or performance of remediation and, in some cases, compensation for alleged property damage, natural resource damages, punitive damages, civil penalties, injunctive relief and government oversight costs.

ENVIRONMENTAL REMEDIATION

As of December 31, 2023, certain Occidental subsidiaries participated in or monitored remedial activities or proceedings at 160 sites. The following table presents the current and non-current environmental remediation liabilities of such subsidiaries on a consolidated basis as of December 31, 2023 and 2022, the current portion of which is included in accrued liabilities ($132 million in 2023 and $141 million in 2022) and the remainder in deferred credits and other liabilities - environmental remediation liabilities ($0.9 billion in 2023 and $0.9 billion in 2022).

These environmental remediation sites are grouped into NPL Sites and the following three categories of non-NPL Sites —Third-Party Sites, Currently Operated Sites and Closed or Non-operated Sites.


	2023			2022
millions, except number of sites	Number of Sites	Remediation Balance		Number of Sites	Remediation Balance
NPL Sites	32	$	435	30	$	445
Third-Party Sites	65	233		68	238
Currently Operated Sites	12	98		13	106
Closed or Non-operated Sites	51	255		51	257
Total	160	$	1,021	162	$	1,046

As of December 31, 2023, environmental remediation liabilities of Occidental subsidiaries exceeded $10 million each at 18 of the 160 sites described above, and 94 of the sites had liabilities from $0 to $1 million each.

The DASS in Newark, New Jersey accounted for a significant portion of the liabilities associated with the category of NPL Sites.

Six of the 65 Third-Party Sites — a chrome site in New Jersey, a former copper mining and smelting operation in Tennessee, a former oil field, a former chemical plant and a landfill in California and an active refinery in Louisiana where Occidental reimburses the current owner for certain remediation activities — accounted for approximately two thirds of the liabilities associated with this category.

Three Currently Operated Sites — oil and gas operations in Colorado and chemical plants in Kansas and Louisiana — accounted for approximately two thirds of the liabilities associated with this category.


102			OXY 2023 FORM 10-K


						FINANCIAL STATEMENTS FOOTNOTES

Eight Closed or Non-operated Sites — a landfill in Western New York, a former refinery in Oklahoma, former chemical plants in California, Michigan, Ohio, Tennessee and Washington, and a closed coal mine in Pennsylvania — accounted for approximately two thirds of the liabilities associated with this category.

The consolidated estimate of environmental remediation liabilities in the table above varies over time depending on factors such as acquisitions or divestitures, identification of additional sites, remedy selection and implementation and changes in applicable laws or regulations, among other factors. Occidental’s subsidiaries recorded environmental remediation expenses of $79 million, $65 million and $28 million for the years ended December 31, 2023, 2022, and 2021, respectively, on a consolidated basis. Environmental remediation expenses primarily relate to changes to existing conditions from past operations. Based on current estimates, Occidental expects its subsidiaries to expend funds corresponding to approximately 40% of the year-end remediation balance over the next three to four years with the remainder over the subsequent 10 or more years.

Occidental believes its range of reasonably possible additional losses of its subsidiaries beyond those amounts currently recorded for environmental remediation for the 160 environmental sites in the table above could be up to $2.6 billion.

MAXUS ENVIRONMENTAL SITES

A significant portion of aggregate estimates of environmental remediation liabilities and reasonably possible additional losses described above relates to the former DSCC. When OxyChem acquired DSCC in 1986, Maxus agreed to indemnify OxyChem for a number of environmental sites, including the DASS. In June 2016, Maxus and several affiliated companies filed for Chapter 11 bankruptcy in the U.S. Bankruptcy Court for the District of Delaware. Prior to filing for bankruptcy, Maxus defended and indemnified OxyChem in connection with remediation costs and other liabilities associated with the sites subject to the indemnity. In 2023, OxyChem recovered on its remaining claims for indemnified costs from the proceeds of litigation brought by the Maxus Liquidating Trust. For additional information on the Maxus Liquidating Trust, see Note 13 - Lawsuits, Claims, Commitments and Contingencies.

DIAMOND ALKALI SUPERFUND SITE

The EPA has organized the DASS into four OUs for evaluating, selecting and implementing remediation under CERCLA. OxyChem’s current activities in each OU are summarized below, many of which are performed on OxyChem’s behalf by Glenn Springs Holdings, Inc.

OU1 – The Former Diamond Alkali Plant at 80-120 Lister Avenue in Newark: Maxus and its affiliates implemented an interim remedy of OU1 pursuant to a 1990 Consent Decree, for which OxyChem currently performs maintenance and monitoring. The EPA is conducting a periodic evaluation of the interim remedy for OU1.

OU2 – The Lower 8.3 Miles of the Lower Passaic River: In March 2016, the EPA issued a ROD specifying remedial actions required for OU2. During the third quarter of 2016, and following Maxus’s bankruptcy filing, OxyChem and the EPA entered into an AOC to complete the design of the remedy selected in the ROD. At that time, the EPA sent notice letters to approximately 100 parties notifying them that they were potentially responsible to pay the costs to implement the remedy in OU2 and announced that it would pursue similar agreements with other potentially responsible parties. In June 2018, OxyChem filed a complaint under CERCLA in U.S. District Court for the District of New Jersey against numerous potentially responsible parties seeking contribution and cost recovery of amounts incurred or to be incurred to comply with the AOC and the OU2 ROD, or to perform other remediation activities related to the DASS (2018 Contribution Action). The District Court has not adjudicated OxyChem’s relative share of responsibility for those costs. The EPA has estimated the cost to remediate OU2 to be approximately $1.4 billion.

OU3 – Newark Bay Study Area, including Newark Bay and Portions of the Hackensack River, Arthur Kill, and Kill van Kull: Maxus and its affiliates initiated a remedial investigation and feasibility study of OU3 pursuant to a 2004 AOC which was amended in 2010. OxyChem is currently performing feasibility study activities in OU3. In September 2022, the EPA listed the Lower Hackensack River (LHR) on the NPL, and this newly listed site comprises several existing NPL sites along a portion of that river that flows into OU3. In January 2024, EPA sent a general notice letter requesting that OxyChem and four other entities coordinate certain investigation activities at the LHR site.

OU4 – The 17-mile Lower Passaic River Study Area, comprising OU2 and the Upper 9 Miles of the Lower Passaic River: In September 2021, the EPA issued a ROD selecting an interim remedy for the portion of OU4 that excludes OU2, and is located upstream from the Lister Avenue Plant site for which OxyChem inherited legal responsibility. The EPA has estimated the cost to remediate OU4 to be approximately $440 million. At this time, OxyChem's role or responsibilities under the OU4 ROD, and those of other potentially responsible parties, have not been adjudicated. To provide continued, efficient remediation progress, in January 2022, OxyChem offered to design and implement the interim remedy for OU4 subject to certain conditions, including a condition that the EPA would not seek to bar OxyChem’s right to seek contribution or cost recovery from any other parties that are potentially responsible to pay for the OU4 interim remedy. In March 2022, the EPA sent a notice letter to OxyChem and other parties requesting good faith offers to implement the selected remedies at OU2 and OU4. OxyChem submitted a good faith offer in June 2022, reaffirming the offer to design the remedy for OU4 and offering to enter into additional sequential agreements to remediate OU2 and OU4, subject to similar conditions, including that the EPA not seek to bar OxyChem from pursuing contribution or cost recovery from other responsible parties. The EPA did not accept OxyChem's June 2022 offer. In March 2023, the EPA issued a Unilateral Administrative Order (OU4 UAO) in which it directed and ordered OxyChem to design the EPA’s selected interim remedy for OU4 and to provide approximately


OXY 2023 FORM 10-K			103


						FINANCIAL STATEMENTS FOOTNOTES

$93 million in financial assurance to secure its performance. Subject to all its defenses, OxyChem is designing the interim remedy in compliance with the OU4 UAO. As a result of OxyChem incurring costs to implement the OU4 UAO, and the EPA's proposal described below to bar OxyChem's contribution claims against various parties, including those asserted in the 2018 Contribution Action, OxyChem filed a cost recovery action under CERCLA in March 2023 in the District Court against multiple parties (2023 Cost Recovery Action).

Natural Resource Trustees – In addition to the activities of the EPA and OxyChem in the OUs described above, federal and state natural resource trustees are assessing natural resources in the Lower Passaic River and Greater Newark Bay to evaluate potential claims for natural resource damages.

ALDEN LEEDS LITIGATION

In December 2022, the EPA and the DOJ filed a proposed Consent Decree in the Alden Leeds litigation seeking court approval to settle with 85 parties for a total of $150 million, which OxyChem believes is based on an unauthorized, flawed and disproportionate allocation of responsibility, release the settling companies from liability to the United States for remediation costs in DASS OU2 and OU4 and bar OxyChem from pursuing contribution against those parties for remediation costs OxyChem had incurred or may incur in the future to design and implement the remedies in OU2 and OU4, including claims OxyChem asserted in the 2018 Contribution Action. The proposed settlement does not address the liability of entities that were excluded from the settlement for the DASS, including OU2, OU3, OU4 or natural resource damages, or the liability of any settling party with respect to OU3 or natural resource damages. The proposed settlement was subject to a public comment period that closed in March 2023. In January 2024, the DOJ filed a proposed Amended Consent Decree in which it excluded three companies from the proposed settlement, among other changes, and a motion to approve the Amended Consent Decree.

OxyChem believes the proposed settlement and Amended Consent Decree rely, improperly, on an allocation report prepared by an EPA contractor in which the contractor purported to assign a disproportionate share of the responsibility for remediation costs in OU2 and OU4 to OxyChem. OxyChem also believes that process was unreasonably limited in scope and unreliably based on voluntary reporting by the settling parties, instead of sworn evidence, publicly available sampling results and historical documents reflecting the operating history and disposal practices of the 82 parties that the EPA proposes to release in this settlement.

OxyChem intends to challenge vigorously the proposed settlement and Amended Consent Decree, as well as the allocation report and process upon which they are based, and to seek contribution and cost recovery from other potentially responsible parties for remediation costs it has incurred or may incur at the DASS. OxyChem's response to the motion to approve the Amended Consent Decree is due in April 2024.

OxyChem does not know when the District Court will rule on the DOJ’s motion to approve the Amended Consent Decree. If the Amended Consent Decree is approved by the District Court and not overturned on appeal, then, notwithstanding OxyChem’s vigorous, good faith effort to contest the settlement proposed in the Alden Leeds litigation, the EPA could attempt to compel OxyChem to bear substantially all the estimated cost to design and implement the OU2 and OU4 remedies. Such a result could have a material adverse impact on OxyChem and Occidental’s consolidated results of operations in the period recorded.

While the remedies for OU2 and OU4 are expected to take over ten years to complete, the EPA may seek to require OxyChem to provide additional financial assurance. In the OU4 UAO, the EPA directed OxyChem to post financial assurance in the amount of approximately $93 million. Subject to all defenses, OxyChem has complied with this directive. The amount of any additional financial assurance is not subject to estimation at this time. It is uncertain when or to what extent the EPA may take action to compel OxyChem to perform further remediation in OU2 or OU4 or the amount of financial assurance the EPA may attempt to require OxyChem to post. For further information on the Alden Leeds litigation, see Note 13 - Lawsuits, Claims, Commitments and Contingencies.

OTHER INFORMATION

For the DASS, OxyChem has accrued a reserve relating to its estimated allocable share of the costs to perform the maintenance and monitoring required in the OU1 Consent Decree, the design and implementation of remedies selected in the OU2 ROD and AOC and the OU4 ROD and OU4 UAO, and the remedial investigation and feasibility study required in OU3.

OxyChem’s accrued environmental remediation reserve does not reflect the potential for additional remediation costs or natural resource damages for the DASS that OxyChem believes are not reasonably estimable. OxyChem’s ultimate liability at the DASS may be higher or lower than the reserved amount and the reasonably possible additional losses, and is subject to final design plans, further action by the EPA and natural resource trustees, and the resolution of OxyChem's allocable share with other potentially responsible parties, among other factors.

OxyChem continues to evaluate the estimated costs currently recorded for remediation at the DASS as well as the range of reasonably possible additional losses beyond those amounts currently recorded. Given the complexity and extent of the remediation efforts, estimates of the remediation costs may increase or decrease over time as new information becomes available.

NOTE 13 - LAWSUITS, CLAIMS, COMMITMENTS AND CONTINGENCIES

LEGAL MATTERS

Occidental or certain of its subsidiaries are involved, in the normal course of business, in lawsuits, claims and other legal proceedings that seek, among other things, compensation for alleged personal injury, breach of contract, property damage or other losses, punitive damages, civil penalties, or injunctive or declaratory relief. Occidental or certain of its subsidiaries also are involved in proceedings under CERCLA and similar federal, regional, state, provincial, tribal, local and international environmental laws. These environmental proceedings seek funding or performance of remediation and, in some cases, compensation for alleged property damage, natural resource damages, punitive damages, civil penalties, injunctive relief and government oversight costs. Usually Occidental or such subsidiaries are among many companies in these environmental proceedings and have to date been successful in sharing remediation costs with other financially sound companies. Further, some lawsuits, claims and legal proceedings involve acquired or disposed assets with respect to which a third party or Occidental or its subsidiary retains liability or indemnifies the other party for conditions that existed prior to the transaction.

In accordance with applicable accounting guidance, Occidental or its subsidiaries accrue reserves for outstanding lawsuits, claims and proceedings when it is probable that a liability has been incurred and the liability can be reasonably estimated. Reserves for matters, other than for the arbitration award (disclosed below), tax matters or environmental remediation, that satisfy these criteria as of December 31, 2023 and 2022, were not material to Occidental’s Consolidated Balance Sheets.

If unfavorable outcomes of these matters were to occur, future results of operations or cash flows for any particular quarterly or annual period could be materially adversely affected. Occidental’s estimates are based on information known about the legal matters and its experience in contesting, litigating and settling similar matters. Occidental will reassess the probability and estimability of contingent losses as new information becomes available.

ANDES ARBITRATION

In 2016, Occidental received payments from the Republic of Ecuador of approximately $1.0 billion pursuant to a November 2015 arbitration award for Ecuador’s 2006 expropriation of Occidental’s Participation Contract for Block 15. The awarded amount represented a recovery of Occidental's 60% of the value of Block 15. In 2017, Andes commenced an arbitration against OEPC, claiming it is entitled to a 40% share of the judgment amount obtained by Occidental. Occidental believes that Andes is not entitled to any of the amounts paid under the 2015 arbitration award because Occidental’s recovery was limited to Occidental’s own 60% economic interest in the block. In March 2021, the arbitration tribunal issued an award in favor of Andes and against OEPC in the amount of $391 million plus interest. In June 2021, OEPC filed a motion to vacate the award due to concerns regarding the validity of the award. In December 2021, the U.S. District Court for the Southern District of New York confirmed the arbitration award, plus prejudgment interest, in the aggregate amount of $558 million. OEPC appealed the judgment. In June 2023, the U.S. Court of Appeals for the Second Circuit confirmed the District Court's ruling with respect to the arbitration award but overturned the District Court's decision to add prejudgment interest in the amount of $166 million, ordering the District Court to recalculate the interest amount. The parties completed briefing on the interest issue in December 2023. Simultaneously, OEPC sought review of the Second Circuit ruling in the U.S. Supreme Court. Andes responded to OEPC’s request on February 2, 2024 and OEPC’s reply is due later in February.

Andes also filed state court claims in New York and Delaware against OEPC, Occidental Petroleum Corporation (OPC) and OXY USA to attempt to recover on its judgment against OEPC during the pendency of the appeal. The New York state court dismissed Andes’ action against OPC with prejudice in March 2023. Andes appealed this ruling and oral argument was set for March 2024. Andes also seeks to recover its judgment from other Occidental entities (which were not a party to the Andes arbitration) in New York federal court and in Delaware state court. Both OXY USA and Andes filed motions for summary judgment in the Delaware state court action. The Delaware state court heard argument on these motions in November 2023.

In addition, OEPC commenced an arbitration against Andes to recover significant additional claims not addressed by the prior arbitration tribunal relating to Andes' 40% share of costs, liabilities, losses and expenses due under the farmout agreement and joint operating agreement to which Andes and OEPC are parties. In July 2023, a majority of the arbitration tribunal declined to award any costs to OEPC based upon the doctrine of res judicata. One arbitrator dissented, noting that the prior arbitration panel expressly noted that it was not ruling on the types of claims asserted by OEPC. Andes has moved to confirm this award and OEPC has moved to vacate the award because of, among other things, what OEPC believes are fundamental legal errors embodied in the award.

Regarding the pending matters discussed above, Andes and the Occidental entities named in the pending actions have jointly requested that the relevant courts adjourn all rulings for sixty days while Andes and OEPC attempt to negotiate settlement terms acceptable to both parties. If acceptable terms cannot be agreed upon, then all Occidental entities will continue to vigorously defend against these actions.

ALDEN LEEDS AND OTHER LITIGATION

As described in Note 12 - Environmental Liabilities and Expenditures, OxyChem intends to challenge vigorously the proposed settlement and Amended Consent Decree in the Alden Leeds litigation, as well as the allocation report and process upon which they are based. In the 2018 Contribution Action and 2023 Cost Recovery Action, OxyChem also intends to defend and prosecute vigorously its right to seek contribution and cost recovery from all potentially responsible parties to pay remediation costs in the DASS and to seek a judicial allocation of responsibility under CERCLA. The 2018 Contribution Action and the 2023 Cost Recovery Action are currently stayed pending the outcome of the Alden Leeds litigation. As the Alden Leeds litigation is in its early stages, OxyChem is unable to estimate the timing of the District Court’s decision, its outcome, or the outcome of any appeals from the District Court’s decision.

MAXUS LIQUIDATING TRUST

As described in Note 12 – Environmental Liabilities and Expenditures, Maxus was contractually obligated to indemnify, defend, and hold harmless OxyChem against environmental liabilities arising from the former operations of DSCC. In June 2016, Maxus filed for bankruptcy protection in the U.S. Bankruptcy Court for the District of Delaware (the Bankruptcy Court). In June 2017, the Bankruptcy Court approved a Plan of Liquidation to liquidate Maxus and create the Trust for the benefit of Maxus’ creditors, including OxyChem, to pursue claims against Maxus’ current and former parents, YPF and Repsol, certain of their respective subsidiaries and affiliates, and others to satisfy claims by OxyChem and other creditors for past and future remediation and other costs. In July 2017, the court-approved Plan of Liquidation became final, and the Trust became effective. Pursuant to the Plan, the Trust is governed by an independent trustee and is not controlled by OxyChem. The Plan authorizes the Trust to distribute any assets it recovers from such litigation claims to the Trust’s beneficiaries, which include OxyChem and other creditors, in accordance with the Plan and governing Trust Agreement.

In June 2018, the Trust filed its complaint against YPF and Repsol in the Bankruptcy Court asserting claims based upon, among other things, fraudulent transfer and alter ego. In April 2023, the Trust, YPF and Repsol reached an agreement to resolve the claims pending in the Bankruptcy Court. Related agreements were executed among the United States Government, YPF and Repsol as well as among OxyChem, YPF and Repsol. Under the settlement, which became final in August 2023, YPF and Repsol paid the Trust $575 million, which the Trust is distributing according to the Plan. OxyChem’s share of these settlement proceeds, under the Plan, is approximately $350 million. OxyChem adjusted its valuation allowance established against its claims against Maxus, resulting in a gain of approximately $260 million in the second quarter of 2023. In October 2023, OxyChem recovered proceeds of $341 million and expects to recover approximately $9 million during 2024.

TAX MATTERS AND OTHER DISPUTES

During the course of its operations, Occidental is subject to audit by tax authorities for varying periods in various federal, state, local and international tax jurisdictions. Tax years through 2021 for U.S. federal income tax purposes have been audited by the IRS pursuant to its Compliance Assurance Program and subsequent taxable years are currently under review. Tax years through 2018 have been audited for state income tax purposes. There are no outstanding significant audit matters in international jurisdictions. During the course of tax audits, disputes have arisen and other disputes may arise as to facts and matters of law.

For Anadarko, its taxable years through 2014 and tax year 2016 for U.S. federal tax purposes have been audited and closed by the IRS. Tax years 2015 and 2017 through 2019 have been audited by the IRS but remain open pending the outcome of the Tronox U.S. Tax court litigation discussed below. Tax years through 2010 have been audited for state income tax purposes. There is one outstanding significant tax matter in an international jurisdiction related to a discontinued operation. As stated above, during the course of tax audits, disputes have arisen and other disputes may arise as to facts and matters of law.

Other than the dispute discussed below, Occidental believes that the resolution of these outstanding tax disputes would not have a material adverse effect on its consolidated financial position or results of operations.

Anadarko received an $881 million tentative refund in 2016 related to its $5.2 billion Tronox Adversary Proceeding settlement payment in 2015. In September 2018, Anadarko received a statutory notice of deficiency from the IRS disallowing the net operating loss carryback and rejecting Anadarko’s refund claim. As a result, Anadarko filed a petition with the U.S. Tax Court to dispute the disallowances in November 2018. Trial was held in May 2023. The parties filed simultaneous post-trial briefs on September 1, 2023 and will file reply briefs on December 7, 2023. Closing arguments are scheduled for May 2024. An opinion by the Tax Court could be issued at any time. If any tax liability is due as a result of the Tax Court’s opinion, it must be fully bonded or paid in full within 90 days of the entry of decision by the Tax Court. If an appeal is not pursued by Anadarko, any resulting tax deficiency will be assessed by the IRS and would be due within 30 days of receiving a formal notice of tax assessment.

In accordance with ASC 740’s guidance on the accounting for uncertain tax positions, Occidental has recorded no tax benefit on the tentative cash tax refund of $881 million. Additionally, Occidental has recorded no tax benefit on approximately $500 million of additional cash tax benefits realized from the utilization of tax attributes generated as a result of the deduction of the $5.2 billion Tronox Adversary Proceeding settlement payment in 2015. As a result, should Occidental not ultimately prevail on the issue, there would be no additional tax expense recorded relative to this position for financial statement purposes other than future interest. However, in that event, as of December 31, 2023, Occidental would be


106			OXY 2023 FORM 10-K


						FINANCIAL STATEMENTS FOOTNOTES

required to repay approximately $1.4 billion in federal taxes, $28 million in state taxes and accrued interest of $574 million. A liability for the taxes and interest is included in deferred credits and other liabilities - other.

INDEMNITIES TO THIRD PARTIES

Occidental, its subsidiaries, or both, have indemnified various parties against specified liabilities those parties might incur in the future in connection with purchases and other transactions that they have entered into with Occidental or its subsidiaries. These indemnities usually are contingent upon the other party incurring liabilities that reach specified thresholds. As of December 31, 2023, Occidental is not aware of circumstances that it believes would reasonably be expected to lead to indemnity claims that would result in payments materially in excess of reserves.

PURCHASE OBLIGATIONS AND COMMITMENTS

Occidental, its subsidiaries, or both, have entered into agreements providing for future payments, primarily to secure terminal and pipeline capacity, and also for drilling rigs and services, electrical power, non-lease components, steam and certain chemical raw materials. Occidental has certain other commitments under contracts, guarantees and joint ventures, including purchase commitments for goods and services at market-related prices and certain other contingent liabilities. The amounts that will be paid for such outstanding off-balance sheet purchase obligations as of December 31, 2023 are $3.2 billion in 2024, $4.1 billion in 2025 and 2026, $2.5 billion in 2027 and 2028 and $2.6 billion in 2029 and thereafter.


NOTE 14 - STOCKHOLDERS’ EQUITY

The following table presents Occidental's common share activity, including exercises of options and warrants, other transactions in Occidental's common stock in 2023 and treasury stock purchased both under its $3.0 billion share repurchase program announced in February 2023 and from the trustee of Occidental's defined contribution savings plan:

Total 2023	4,844,795		4,159,079		(29,399,715)		879,463,103

(a) Approximately $112 million of cash was received as a result of the exercise of common stock warrants and options.

(b) Consisted of issuances for the 2015 long-term incentive plan, the OPC savings plan and the dividend reinvestment plan.

(c) Included purchases of shares from the trustee of Occidental's defined contribution savings plan that are not part of publicly announced plans or programs.

(d) As of December 31, 2023, Occidental had 99.5 million outstanding warrants with a strike price of $22 per share and 83.9 million of warrants with a strike price of $59.62 per share.

TREASURY STOCK

Under the share repurchase program announced in February 2023, Occidental purchased 29.1 million shares for $1.8 billion during 2023. Additionally, Occidental purchased shares from the trustee of its defined contribution savings plan in 2023, 2022 and 2021. As of December 31, 2023, 2022 and 2021, treasury stock shares numbered 228.1 million, 198.7 million and 149.3 million, respectively.

PREFERRED STOCK

Less: Preferred redemptions			(15,103)
Preferred stock, as of December 31, 2023			84,897

The carrying value of preferred stock is less than the face value. The difference between carrying value and face value, along with the redemption premium, reduces net income available to common stockholders. The following presents the components of preferred stock dividends and redemptions:


millions	Year ended December 31, 2023
Preferred dividends	$	736
Redemption premium	151
Redemption value in excess of carrying value	36
Preferred dividend and redemption premiums	$	923

BERKSHIRE WARRANT

In connection with the preferred stock issuance, Occidental also issued the Berkshire Warrant. The Berkshire Warrant is exercisable at the holder’s option, in whole or in part, until the first anniversary of the date on which no shares of preferred stock remain outstanding, at which time the Berkshire Warrant expires. The holder of the Berkshire Warrant and the preferred stock may redeem the preferred stock as payment for the exercise price of the Warrant in lieu of cash payment upon exercise. As of December 31, 2023, the Berkshire warrant would result in the issuance of 83.9 million shares of Occidental common stock, if exercised in full for its current strike price of $59.62 per share of Occidental common stock.

COMMON STOCK WARRANTS

On June 26, 2020, the Board of Directors declared Common Stock Warrants, at a rate of 0.125 warrants per share of Occidental common stock. Occidental issued approximately 116 million Common Stock Warrants on August 3, 2020 to holders of record of outstanding shares of Occidental’s common stock as of the close of business on July 6, 2020, and pursuant to Occidental’s outstanding equity-based incentive awards in connection with anti-dilution adjustments resulting from such distribution. The Common Stock Warrants have an exercise price of $22.00 per share and will expire on August 3, 2027. The Common Stock Warrants are listed on the NYSE and trade under the symbol "OXY WS". As of December 31, 2023, Occidental had 99.5 million outstanding warrants.

The Common Stock Warrants were measured at fair value on the declaration date using the Black-Scholes option model and were classified as equity in "Additional paid-in capital". The following level 2 inputs were used in the Black-Scholes option model: the expected life of the Common Stock Warrants, a volatility factor and the exercise price. The expected life is based on the estimated term of the Common Stock Warrants, the volatility factor is based on historical volatilities of Occidental common stock and the exercise of $22.00 per share of Occidental common stock.

EARNINGS PER SHARE

Occidental’s instruments containing rights to nonforfeitable dividends granted in stock-based awards are considered participating securities prior to vesting and, therefore, have been deducted from earnings in computing basic and diluted EPS under the two-class method.

Basic EPS was computed by dividing net income attributable to common stock, net of income allocated to participating securities, by the weighted-average number of common shares outstanding during each period, including vested but

unissued shares and share units. The computation of diluted EPS reflects the additional dilutive effect of stock options, warrants and unvested stock awards.

The following table presents the calculation of basic and diluted EPS for the years ended December 31:

NOTE 15 - STOCK-BASED INCENTIVE PLANS

Occidental issues stock-based awards to employees in accordance with the terms of the Plans. An aggregate of 133 million shares of Occidental common stock were authorized for issuance and approximately 14.1 million shares had been reserved for issuance for employee awards through December 31, 2023. As of December 31, 2023, approximately 45.0 million shares were available for grants of future awards. The 2015 Long-Term Incentive plan requires each share covered by an award (other than options) to be counted as if three shares were issued in determining the number of shares that are available for future awards. Accordingly, the number of shares available for future awards may be less than 45.0 million depending on the type of award granted, and shares available for future awards may increase by the number of shares that are forfeited, canceled, or correspond to the portion of any stock-based awards settled in cash, including awards that were issued under a previous plan that remain outstanding. Current outstanding awards include RSUs, stock options, CROCEI awards and TSRI awards.

During 2023, non-employee directors were granted awards for 36,106 shares of common stock. Compensation expense for these awards was measured using the closing quoted market price of Occidental’s common stock on the grant date and was fully recognized at that time.


OXY 2023 FORM 10-K			109


						FINANCIAL STATEMENTS FOOTNOTES

Occidental incurred expenses of $217 million, $258 million and $287 million related to stock-based incentive plans in the years ended December 31, 2023, 2022, and 2021, respectively. The income tax benefit associated with this expense was $46 million, $54 million and $60 million in the years ended December 31, 2023, 2022, and 2021, respectively.

As of December 31, 2023, unrecognized compensation expense for all unvested stock-based incentive awards was $283 million. This expense is expected to be recognized over a weighted-average period of 1.9 years. Occidental accounts for forfeitures as they occur.

RESTRICTED STOCK UNITS

Certain employees are awarded the right to receive RSUs, some of which have performance criteria, and are in the form of, or equivalent in value to, actual shares of Occidental common stock. Depending on their terms, RSUs may be settled in stock or may be cash settled liabilities. These awards vest from one to three years following the grant date. For certain RSUs, dividend equivalents are paid during the vesting period.

CASH-SETTLED RSU LIABILITY AWARDS

The weighted-average, grant-date fair values of cash-settled RSUs granted in 2023, 2022, and 2021 were $60.43, $47.41 and $25.83 per share, respectively. Cash-settled RSUs resulted in payments of $9 million, $203 million and $4 million, during the years ended December 31, 2023, 2022, and 2021, respectively.

STOCK-SETTLED RSU EQUITY AWARDS

The weighted-average, grant-date fair values of the stock-settled RSUs granted in 2023, 2022, and 2021 were $59.85, $45.14 and $25.45, respectively. The fair value of RSUs settled in shares during the years ended December 31, 2023, 2022, and 2021 was $254 million, $160 million and $70 million, respectively.

A summary of changes in Occidental’s unvested cash- and stock-settled RSUs for 2023, is presented below:


	Cash-Settled			Stock-Settled
thousands, except fair values	RSUs			RSUs
Unvested as of January 1	298	$	37.96	8,894	$	36.70

Unvested as of December 31	271	$	49.53	7,732	$	47.03

TOTAL SHAREHOLDER RETURN INCENTIVE AWARDS

Certain executives are awarded TSRIs that vest at the end of a three-year period following the grant date. Payout is based upon Occidental’s absolute total shareholder return and performance relative to its peers. TSRIs have payouts that range from 0% to 200% of the target award and settle in stock once certified. Dividend equivalents for TSRIs are accumulated and paid upon certification of the award. The fair value of TSRIs settled in shares during the years ended December 31, 2023, 2022, and 2021 was $45 million, zero and $4 million, respectively.

The fair values of TSRIs are initially determined on the grant date using a Monte Carlo simulation model based on Occidental’s assumptions, noted in the following table, and the volatility from corresponding peer group companies. The expected life is based on the Term. The risk-free interest rate is the implied yield available on zero coupon Treasury notes at the time of grant with a remaining term equal to the Term. The dividend yield is the expected annual dividend yield over the Term, expressed as a percentage of the stock price on the grant date. Estimates of fair value may not accurately predict the value ultimately realized by the employees who receive the awards, and the ultimate value may not be indicative of the reasonableness of the original estimates of fair value made by Occidental.

The grant-date assumptions used in the Monte Carlo simulation models for the estimated payout level of TSRIs were as follows:


	TSRIs
	2023		2022		2021
Assumptions used:
Risk-free interest rate	4.6%		1.7%		0.2%
Volatility factor	64%		80%		75%
Expected life, years	2.84		2.89		2.88
Grant-date fair value of underlying Occidental common stock	$	59.71	$	42.98	$	25.39

Occidental conducts its operations through three segments: (1) oil and gas; (2) chemical; and (3) midstream and marketing. The factors used to identify these segments are based on the nature of the operations that are undertaken in each segment. Income taxes, interest income, interest expense, environmental remediation expenses, acquisition-related costs and unallocated corporate expenses are included under corporate and eliminations. Intersegment sales eliminate upon consolidation and are generally made at prices approximating those that the selling entity would be able to obtain in third-party transactions. Identifiable assets are those assets used in the operations of the segments. Corporate assets consist of cash and restricted cash, certain corporate receivables and PP&E. The chief operating decision maker analyzes each segment’s operating results to make decisions about resources to be allocated to the segment and to assess its performance as well as Occidental’s overall performance.

Supplemental Oil and Gas Information

OIL AND GAS RESERVES

The following tables set forth Occidental’s net interests in quantities of proved developed and undeveloped reserves of oil, NGL and natural gas and changes in such quantities. Proved oil, NGL and natural gas reserves were estimated using the unweighted arithmetic average of the first-day-of-the-month price for each month within the year, unless prices were defined by contractual arrangements. Oil, NGL and natural gas prices used for this purpose were based on posted benchmark prices and adjusted for price differentials including gravity, quality and transportation costs. The following table shows the pricing used in the reserve analysis for the periods presented:


	2023		2022		2021
Average WTI Oil ($/Bbl)	$	78.22	$	93.67	$	66.56
Average Brent Oil ($/Bbl)	$	82.80	$	97.77	$	69.24
Average Henry Hub Natural Gas ($/MMbtu)	$	2.64	$	6.36	$	3.60
Average Mt. Belvieu NGL ($/Bbl)	$	29.94	$	47.81	$	44.22

Reserves are stated net of applicable royalties. Estimated reserves include Occidental’s economic interests under PSCs and other similar economic arrangements. In addition, discussions of oil and gas production or volumes, in general, refer to sales volumes unless the context requires or it is indicated otherwise.

Prices for oil, NGL and natural gas fluctuate widely. Historically, the markets for oil, NGL and natural gas and refined products have been volatile and may continue to be volatile in the future. Prolonged declines in oil, NGL and natural gas prices would reduce Occidental’s operating results and cash flows and could impact its future rate of growth and the recoverability of the carrying value of its assets.

STANDARDIZED MEASURE, INCLUDING YEAR-TO-YEAR CHANGES THEREIN, OF DISCOUNTED FUTURE NET CASH FLOWS

For purposes of the following disclosures, future cash flows were computed by applying to Occidental’s proved oil and gas reserves the unweighted arithmetic average of the first-day-of-the-month price for each month within the years ended December 31, 2023, 2022 and 2021, respectively, unless prices were defined by contractual arrangements, and exclude escalations based upon future conditions. The realized prices used to calculate future cash flows vary by producing area and market conditions. Future operating and capital costs were forecast using the current cost environment applied to expectations of future operating and development activities to develop and produce proved reserves at year end.

Future income tax expenses were computed by applying, generally, year-end statutory tax rates (adjusted for permanent differences, tax credits, allowances and foreign income repatriation considerations) to the estimated net future pre-tax cash flows. The discount was computed by application of a 10% discount factor. The calculations assumed the continuation of existing economic, operating and contractual conditions as of December 31, 2023, 2022 and 2021. Such assumptions, which are required by regulation, have not always proven accurate in the past. Other valid assumptions would give rise to substantially different results.

Occidental’s investment in developed and undeveloped acreage comprises numerous concessions, blocks and leases. Work programs are designed to ensure that the exploration potential of any property is fully evaluated before the contractual expiration date. In some instances, Occidental may elect to relinquish acreage in advance of the contractual expiration date if the evaluation process is complete and there is not a business basis for extension. In cases where additional time may be required to fully evaluate acreage, Occidental has generally been successful in obtaining extensions. Scheduled lease and concession expirations for undeveloped acreage over the next three years are not expected to have a material adverse impact on Occidental.

OIL, NGL AND NATURAL GAS SALES VOLUMES PER DAY

The following tables set forth the sales volumes from ongoing operations of oil, NGL and natural gas per day for each of the three years in the period ended December 31, 2023. The differences between the sales and production volumes per day are negligible and are generally due to the timing of shipments at Occidental’s international locations where product is loaded onto tankers. Natural gas volumes have been converted to Boe based on energy content of six Mcf of gas to one barrel of oil.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

Occidental had no changes in, and no disagreements with, Occidental’s accountants on accounting and financial disclosure.

ITEM 9A. CONTROLS AND PROCEDURES


MANAGEMENT’S ANNUAL ASSESSMENT OF AND REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of Occidental Petroleum Corporation and its subsidiaries is responsible for establishing and maintaining adequate internal control over financial reporting. Occidental’s system of internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of Consolidated Financial Statements for external purposes in accordance with GAAP. Occidental’s internal control over financial reporting includes those policies and procedures that: (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and divestitures of Occidental’s assets; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP and that Occidental’s receipts and expenditures are being made only in accordance with authorizations of Occidental’s management and directors; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of Occidental’s assets that could have a material effect on the financial statements.

Management has assessed the effectiveness of Occidental’s internal control system as of December 31, 2023, based on the criteria for effective internal control over financial reporting described in Internal Control - Integrated Framework issued in 2013 by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this assessment, management believes that, as of December 31, 2023, Occidental’s system of internal control over financial reporting is effective.

Occidental’s independent auditors, KPMG LLP, have issued an audit report on Occidental’s internal control over financial reporting.


DISCLOSURE CONTROLS AND PROCEDURES

Occidental’s President and Chief Executive Officer and its Senior Vice President and Chief Financial Officer supervised and participated in Occidental’s evaluation of its disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report. Based upon that evaluation, Occidental’s President and Chief Executive Officer and Senior Vice President and Chief Financial Officer concluded that Occidental’s disclosure controls and procedures were effective as of December 31, 2023.
