SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]
BASIS OF PRESENTATION	NOTE 2 Basis of Presentation The unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission, or SEC, for Form 10-Q. Certain information and note disclosures normally included in the annual financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to those rules and regulations, although the Company believes that the disclosures made are adequate to make the information not misleading. Accordingly, these condensed consolidated financial statements and related notes should be read in conjunction with the consolidated financial statements and related notes in the Company's annual report on Form 10-K for fiscal year 2021 as filed with the SEC on March 11, 2022. The condensed consolidated financial statements include the accounts of Artesian Resources Corporation and its wholly owned subsidiaries, including its principal operating company, Artesian Water. In the opinion of the Company, the accompanying unaudited condensed consolidated financial statements reflect all normal recurring adjustments (unless otherwise noted) necessary to present fairly the Company's balance sheet position as of March 31, 2022, the results of its operations for the three-month periods ended March 31, 2022 and March 31, 2021, its cash flows for the three-month periods ended March 31, 2022 and March 31, 2021 and the changes in stockholders’ equity for the three-month periods ended March 31, 2022 and March 31, 2021. The December 31, 2021 Condensed Consolidated Balance Sheet was derived from the Company’s December 31, 2021 audited consolidated financial statements, but does not include all disclosures and notes normally provided in annual financial statements. The results of operations for the interim periods presented are not necessarily indicative of the results for the full year or for future periods. Use of Estimates The condensed consolidated financial statements were prepared in conformity with generally accepted accounting principles in the U.S., which require management to make certain estimates and assumptions regarding the reported amounts of assets and liabilities including unbilled revenues, credit losses and reserves for bad debt, regulatory asset recovery, lease agreements and contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from management's estimates. All additions to utility plant are recorded at cost. Business combinations pursuant to ASC Topic 805 may result in a purchase price allocation and the acquired assets are required to be evaluated by the applicable regulatory agency. Artesian Wastewater acquired TESI in January 2022. As of March 31, 2022, the accounting for the transaction was preliminary. Management’s preliminary determination of fair value of the tangible assets acquired using the cost method requires management to make significant estimates and assumptions related to economic lives of the assets, replacement costs, and physical characteristics of the tangible assets acquired. A third party valuation specialist will assist with the valuation of the assets acquired. The purchase price allocation is expected to be finalized once the valuation of assets acquired has been completed, no later than one year after the acquisition date. Reclassification Certain accounts in the prior year financial statements have been reclassified for comparative purposes to conform with the presentation in the current year financial statements. These reclassifications had no effect on net income or stockholders' equity.

REVENUE RECOGNITION

REVENUE RECOGNITION	3 Months Ended
REVENUE RECOGNITION	Mar. 31, 2022
REVENUE RECOGNITION [Abstract]
REVENUE RECOGNITION	NOTE 3 – REVENUE RECOGNITION Background Artesian’s operating revenues are primarily attributable to contract services based upon tariff rates approved by the Delaware Public Service Commission, or DEPSC, the Maryland Public Service Commission, or MDPSC, and the Pennsylvania Public Utility Commission, or PAPUC. Tariff contract service revenues consist of water consumption, industrial wastewater services, fixed fees for water and wastewater services including customer and fire protection fees, service charges and Distribution System Improvement Charges, or DSIC, billed to customers at rates outlined in our tariffs that represent stand-alone selling prices. Our non-tariff contract revenues consist of Service Line Protection Plan, or SLP Plan, fees, water and wastewater contract operations, design and installation contract services, and wastewater inspection fees. Other operating revenue primarily consists of developer guarantee contributions for wastewater and rental income for antenna agreements, which are not considered in the scope of Accounting Standards Codification 606, Revenue from Contracts with Customers. Tariff Contract Revenues Artesian generates revenue from the sale of water to customers in Delaware, Cecil County, Maryland, and Southern Chester County, Pennsylvania once a customer requests service in our territory. We recognize water consumption revenue at tariff rates on a cycle basis for the volume of water transferred to customers based upon meter readings for actual gallons of water consumed as well as unbilled amounts for estimated usage from the date of the last meter reading to the end of the accounting period. As actual usage amounts are known based on recurring meter readings, adjustments are made to the unbilled estimates in the next billing cycle based on the actual results. Estimates are made on an individual customer basis, based on one of three methods: the previous year’s consumption in the same period, the previous billing period’s consumption, or averaging. While actual usage for individual customers may differ materially from the estimate based on management judgments described above, we believe the overall total estimate of consumption and revenue for the fiscal period will not differ materially from actual billed consumption. The majority of our water customers are billed for water consumed on a monthly basis, while the remaining customers are billed on a quarterly basis. As a result, we record unbilled operating revenue (contract asset) for any estimated usage through the end of the accounting period that will be billed in the next monthly or quarterly billing cycle. Artesian generates revenue from industrial wastewater services provided to a customer in Sussex County, Delaware. We recognize industrial wastewater service revenue at a contract rate on a monthly basis for the volume of wastewater transferred to Artesian’s wastewater facilities based upon meter readings for actual gallons of wastewater transferred. These services are invoiced at the end of every month based on the actual meter readings for that month, and therefore there is no contract asset or liability associated with this revenue. The contract also provides for a minimum required volume of wastewater flow to our facility. At each year end, any shortfall of the actual volume from the required minimum volume is billed to the industrial customer and recorded as revenue. Additionally, if during the course of the year it is probable that the actual volume will not meet the minimum required volume, estimated revenue amounts would be recorded for the pro rata minimum volume, constrained for potential flow capacity that could occur in the remainder of the year. Pursuant to a settlement agreement, the minimum required volume was prorated on a seven month basis beginning June 1, 2021 and ending December 31, 2021. Artesian generates revenue from metered wastewater services provided to customers in Sussex County, Delaware. We recognize metered wastewater services at tariff rates on a cycle basis for the volume of wastewater transferred to Artesian’s wastewater facilities based upon meter readings for actual gallons of water transferred, as well as unbilled amounts for estimated volume from the date of the last meter reading to the end of the accounting period. As actual volume amounts are known based on recurring meter readings, adjustments are made to the unbilled estimates in the next billing cycle based on the actual results. Estimates are made on an individual customer basis, based on one of three methods: the previous year’s volume in the same period, the previous billing period’s volume, or averaging. While actual usage for individual customers may differ materially from the estimate based on management judgments described above, we believe the overall total estimate of volume and revenue for the fiscal period will not differ materially from actual billed consumption. The majority of these wastewater customers are billed for the volume of water transferred on a quarterly basis. As a result, we record unbilled operating revenue (contract asset) for any estimated volume through the end of the accounting period that will be billed in the next monthly cycle. Artesian generates fixed fee revenue for water and wastewater services provided to customers once a customer requests service in our territory. Our wastewater territory is located in Sussex County, Delaware. We recognize revenue from these services on a ratable basis over time as the customer simultaneously receives and consumes all the benefits of the Company remaining ready to provide them water and wastewater service. These contract services are billed either in advance or arrears at tariff rates on a monthly, quarterly or semi-annual basis. For contract services billed in arrears, we record unbilled operating revenue (contract asset) for any services through the end of the accounting period that will be billed in the next monthly or quarterly cycle. For contract services billed in advance, we record deferred revenue (contract liability) and accounts receivable for any amounts for which we have a right to invoice but for which services have not been provided. This deferred revenue is netted with unbilled operating revenue on the Condensed Consolidated Balance Sheet. Artesian generates service charges primarily from non-payment fees, such as water shut off and reconnection fees and finance charges. These fees are billed and recognized as revenue at the point in time when our tariffs indicate the Company has the right to payment such as days past due have been reached or shut-offs and reconnections have been performed. There is no contract asset or liability associated with these fees. Artesian generates revenue from DSIC, which are surcharges applied to water customer tariff rates in Delaware related to specific types of water distribution system improvements. This rate is calculated on a semi-annual basis based on an approved projected revenue requirement over the following six-month period. This rate is adjusted up or down at the next DSIC filing to account for any differences between actual earned revenue and the projected revenue requirement. Since DSIC revenue is a surcharge applied to tariff rates, we recognize DSIC revenue based on the same guidelines as noted above depending on whether the surcharge was applied to consumption revenue or fixed fee revenue. Accounts receivable related to tariff contract revenues are typically due within 25 days of invoicing. An allowance for doubtful accounts is calculated as a percentage of total associated revenues based upon historical trends and adjusted for current conditions. We mitigate our exposure to credit losses by discontinuing services in the event of non-payment; accordingly, the related allowance for doubtful accounts and associated bad debt expense has not been significant. However, due to the COVID-19 pandemic causing hardships for many utility customers, the Company experienced longer receivable cycles throughout 2020 and into 2021 and made an adjustment to increase the reserve for bad debt by $0.5 million in 2020. In June 2021 we made an adjustment to reduce the reserve by $0.3 million. We will continue to monitor factors that affect the reserve for bad debt. Non-tariff Contract Revenues Artesian generates SLP Plan revenue once a customer requests service to cover all parts, materials and labor required to repair or replace leaking water service lines, leaking or clogged sewer lines, or water and wastewater lines within the customer’s residence, up to an annual limit. We recognize revenue from these services on a ratable basis over time as the customer simultaneously receives and consumes all the benefits of having service line protection services. These contract services are billed in advance on a monthly or quarterly basis. As a result, we record deferred revenue (contract liability) and accounts receivable for any amounts for which we have a right to invoice but for which services have not been provided. Accounts receivable from SLP Plan customers are typically due within 25 days of invoicing. An allowance for doubtful accounts is calculated as a percentage of total SLP Plan contract revenue. We mitigate our exposure to credit losses by discontinuing services in the event of non-payment; accordingly, the related allowance for doubtful accounts and associated bad debt expense has not been significant. Artesian generates contract operation revenue from water and wastewater operation services provided to customers. We recognize revenue from these operation contracts, which consist primarily of monthly operation and maintenance services over time as customers receive and consume the benefits of such services performed. These services are invoiced in advance at the beginning of every month and are typically due within 30 days, and therefore there is no contract asset or liability associated with these revenues. An allowance for doubtful accounts is provided based on a periodic analysis of individual account balances, including an evaluation of days outstanding, payment history, recent payment trends, and our assessment of our customers’ creditworthiness. The related allowance for doubtful accounts and associated bad debt expense has not been significant. Artesian generates design and installation revenue for services related to the design and construction of wastewater infrastructure for a state agency under contract. We recognize revenue from these services over time as services are performed using the percentage-of-completion method based on an input method of incurred costs (cost-to-cost). These services are invoiced at the end of every month based on incurred costs to date. As of March 31, 2022, there is no associated contract asset or liability. There is no allowance for doubtful accounts or bad debt expense associated with this revenue. Artesian generates inspection fee revenue for inspection services related to onsite wastewater collection systems installed by developers of new communities. These fees are paid by developers in advance when a service is requested for a new phase of a development. Inspection fee revenue is recognized on a per lot basis once the inspection of the infrastructure that serves each lot is completed. As a result, we record deferred revenue (contract liability) for any amounts related to infrastructure not yet inspected. There are no accounts receivable, allowance for doubtful accounts or bad debt expense associated with inspection fee contracts. Sales Tax The majority of Artesian’s revenues are earned within the State of Delaware, where there is no sales tax. Revenues earned in the State of Maryland and the Commonwealth of Pennsylvania are related primarily to the sale of water by a public water utility and are exempt from sales tax. Therefore, no sales tax is collected on revenues .

The changes in Contract Assets and Deferred Revenue are primarily due to normal timing differences between our performance and customer payments. Remaining Performance Obligations As of March 31, 2022 and December 31, 2021, Deferred Revenue – Tariff is recorded net of contract assets within Unbilled operating revenues and represents our remaining performance obligations for our fixed fee water and wastewater services, all of which are expected to be satisfied and associated revenue recognized in the next three months. As of March 31, 2022 and December 31, 2021, Deferred Revenue – Non-Tariff is recorded within Other current liabilities and represents our remaining performance obligations for our SLP Plan services and wastewater inspections, which are expected to be satisfied and associated revenue recognized within the next three months and one year for the SLP Plan revenue and inspection fee revenue, respectively.

LEASES [Abstract]
LEASES	NOTE 4 – LEASES The Company leases land and office equipment under operating leases from non-related parties. Our leases have remaining lease terms of 20 years to 74 years, some of which include options to automatically extend the leases for up to 66 years. Payments made under operating leases are recognized in the consolidated statement of operations on a straight-line basis over the period of the lease. The annual lease payments for the land operating leases increase each year either by the most recent increase in the Consumer Price Index or by 3%, as applicable based on the lease agreements. Periodically, the annual lease payment for one operating land lease is determined based on the fair market value of the applicable parcel of land. None of the operating leases contain contingent rent provisions. The commencement date of all the operating leases is the earlier of the date we become legally obligated to make rent payments or the date we may exercise control over the use of the land or equipment. The Company currently does not have any financing leases and does not have any lessor leases that require disclosure. Management made certain assumptions related to the separation of lease and nonlease components and to the discount rate used when calculating the right of use asset and liability amounts for the operating leases. As our leases do not provide an implicit rate, we use our incremental borrowing rates for long term and short term agreements and apply the rates accordingly based on the term of the lease agreements to determine the present value of lease payments. Rent expense for all operating leases except those with terms of 12 months or less comprises: (in thousands) Three Months Ended Three Months Ended March 31, 2022 March 31, 2021 Minimum rentals $ 7 $ 7 Contingent rentals – – $ 7 $ 7 Supplemental cash flow information related to leases is as follows: (in thousands) Three Months Ended Three Months Ended March 31, 2022 March 31, 2021 Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 7 $ 7 Right-of-use assets obtained in exchange for lease obligations: Operating leases $ 446 $ 455 Supplemental balance sheet information related to leases is as follows: (in thousands, except lease term and discount rate) March 31, 2022 December 31, 2021 Operating Leases: Operating lease right-of-use assets $ 446 $ 451 Other current liabilities $ 2 6 Operating lease liabilities 440 440 Total operating lease liabilities $ 442 $ 446 Weighted Average Remaining Lease Term Operating leases 61 years 61 Weighted Average Discount Rate Operating leases 5.0 % 5.0 % Maturities of operating lease liabilities that have initial or remaining non-cancelable lease terms in excess of one year as of March 31, 2022 are as follows: (in thousands) Operating Leases Year 2023 $ 24 2024 24 2025 24 2026 24 2027 25 Thereafter 1,332 Total undiscounted lease payments $ 1,453 Less effects of discounting (1,011 ) Total lease liabilities recognized $ 442 As of March 31, 2022, we have not entered into operating or finance leases that will commence at a future date.

STOCK COMPENSATION PLANS	NOTE 5 – STOCK COMPENSATION PLANS On December 9, 2015, the Company's stockholders approved the 2015 Equity Compensation Plan, or the 2015 Plan. The 2015 Plan provides that grants may be in any of the following forms: incentive stock options, nonqualified stock options, stock units, stock awards, dividend equivalents and other stock-based awards. The 2015 Plan is administered and interpreted by the Compensation Committee, or the Committee, of the Board of Directors of the Company, or the Board. The Committee has the authority to determine the individuals to whom grants will be made under the 2015 Plan, the type, size and terms of the grants, the time when grants will be made and the duration of any applicable exercise or restriction period (subject to the limitations of the 2015 Plan), and deal with any other matters arising under the 2015 Plan. The Committee presently consists of three directors, each of whom is a non-employee director of the Company.

REGULATORY ASSETS	N OTE 7 - REGULATORY ASSETS The FASB ASC Topic 980 stipulates generally accepted accounting principles for companies whose rates are established or subject to approvals by a third-party regulatory agency. Certain expenses are recoverable through rates charged to our customers, without a return on investment, and are deferred and amortized during future periods using various methods as permitted by the DEPSC, MDPSC, and PAPUC. The deferred income taxes will be amortized over future years as the tax effects of temporary differences that previously flowed through to our customers are reversed. Debt related costs include debt issuance costs and other debt related expense. The DEPSC has approved deferred regulatory accounting treatment for issuance costs associated with Artesian Water’s First Mortgage bonds. Debt issuance costs and other debt related expenses are reviewed during Artesian Water’s rate applications as part of its cost of capital calculations.

REGULATORY LIABILITIES [Abstract]
REGULATORY LIABILITIES	NOTE 8 FASB ASC Topic 980 stipulates generally accepted accounting principles for companies whose rates are established or subject to approvals by a third-party regulatory agency. Certain obligations are deferred and/or amortized as determined by the DEPSC, MDPSC, and PAPUC. Regulatory liabilities represent excess recovery of cost or other items that have been deferred because it is probable such amounts will be returned to customers through future regulated rates. Utility plant retirement cost obligation consists of estimated costs related to the potential removal and replacement of facilities and equipment on the Company’s water and wastewater properties. Effective January 1, 2012, as authorized by the DEPSC, when depreciable units of utility plant are retired, any cost associated with retirement, less any salvage value or proceeds received, is charged to a regulated retirement liability. Each year the liability is increased by an annual amount authorized by the DEPSC. Pursuant to the enactment of the Tax Cuts and Jobs Act, or TCJA, on December 22, 2017, the Company adjusted its existing deferred income tax balances to reflect the decrease in the corporate income tax rate from 34% to 21% (see Note 11) resulting in a decrease in the net deferred income tax liability of $24.3 million, of which $22.8 million was reclassified to a regulatory liability related to Artesian Water and Artesian Water Maryland. The regulatory liability amount is subject to certain Internal Revenue Service normalization rules that require the benefits to customers be spread over the remaining useful life of the underlying assets giving rise to the associated deferred income taxes. On January 31, 2019, the DEPSC approved the amortization of the regulatory liability amount of $22.2 million over a period of 49.5 years beginning February 1, 2018, subject to audit at a later date. This audit is currently underway by the DEPSC, with no final ruling yet made. The MDPSC has not issued a final order on the regulatory liability amount of $0.6 million regarding the effects of the TCJA on Maryland customers.

REGULATORY PROCEEDINGS [Abstract]
REGULATORY PROCEEDINGS	N OTE 10 - REGULATO Our water and wastewater utilities generate operating revenue from customers based on rates that are established by state Public Service Commissions through a rate setting process that may include public hearings, evidentiary hearings and the submission of evidence and testimony in support of the requested level of rates by the Company. We are subject to regulation by the following state regulatory commissions: • The DEPSC, regulates both Artesian Water and Artesian Wastewater. • The MDPSC, regulates both Artesian Water Maryland and Artesian Wastewater Maryland. • The PAPUC, regulates Artesian Water Pennsylvania. Our water and wastewater utility operations are also subject to regulation under the federal Safe Drinking Water Act of 1974, or Safe Drinking Water Act, the Clean Water Act of 1972, or the Clean Water Act, and related state laws, and under federal and state regulations issued under these laws. These laws and regulations establish criteria and standards for drinking water and for wastewater discharges. Capital expenditures and operating costs required as a result of water quality standards and environmental requirements have been traditionally recognized by state regulatory commissions as appropriate for inclusion in establishing rates. Water and Wastewater Rates Our regulated utilities periodically seek rate increases to cover the cost of increased operating expenses, increased financing expenses due to additional investments in utility plant and other costs of doing business. In Delaware, utilities are permitted by law to place rates into effect, under bond, on a temporary basis pending completion of a rate increase proceeding. The first temporary increase may be up to the lesser of $ Other Proceedings Delaware law permits water utilities to put into effect, on a semi-annual basis, increases related to specific types of distribution system improvements through a DSIC. This charge may be implemented by water utilities between general rate increase applications that normally recognize changes in a water utility's overall financial position. The DSIC approval process is less costly when compared to the approval process for general rate increase requests. The DSIC rate applied between base rate filings is capped at 7.50% of the amount billed to customers under otherwise applicable rates and charges, and the DSIC rate increase applied cannot exceed 5.0% within an y 12-month period. The following table summarizes (1) Artesian Water’s applications with the DEPSC to collect DSIC rates and (2) the rates upon which eligible plant improvements are based: Application Date 11/20/2020 DEPSC Approval Date 12/14/2020 Effective Date 01/01/2021 Cumulative DSIC Rate 7.50% Net Eligible Plant Improvements – Cumulative Dollars (in millions) $43.1 Eligible Plant Improvements – Installed Beginning Date 10/01/2014 Eligible Plant Improvements – Installed Ending Date 04/30/2019 The rate reflects the eligible plant improvements installed through April 30, 2019. The DSIC rate effective January 1, 2021 is still subject to audit by the DEPSC at a later date. For each of the three months ended March 31, 2022 and March 31, 2021, we earned approximately $1.2 million in DSIC revenue.

INCOME TAXES [Abstract]
INCOME TAXES	NOTE 11 – INCOME TAXES Deferred income taxes are provided in accordance with FASB ASC Topic 740 on all differences between the tax basis of assets and liabilities and the amounts at which they are carried in the consolidated financial statements based on the enacted tax rates expected to be in effect when such temporary differences are expected to reverse. The Company’s rate regulated utilities recognize regulatory liabilities, to the extent considered in ratemaking, for deferred taxes provided in excess of the current statutory tax rate and regulatory assets for deferred taxes provided at rates less than the current statutory rate. Such tax-related regulatory assets and liabilities are reported at the revenue requirement level and amortized to income as the related temporary differences reverse, generally over the lives of the related properties. Under FASB ASC Topic 740, an uncertain tax position represents our expected treatment of a tax position taken, or planned to be taken in the future, that has not been reflected in measuring income tax expense for financial reporting purposes. The Company establishes reserves for uncertain tax positions based upon management's judgment as to the sustainability of these positions. These accounting estimates related to the uncertain tax position reserve require judgments to be made as to the sustainability of each uncertain tax position based on its technical merits. The Company believes its tax positions comply with applicable law and that it has adequately recorded reserves as required. However, to the extent the final tax outcome of these matters is different than the estimates recorded, the Company would then adjust its tax reserves or unrecognized tax benefits in the period that this information becomes known. The Company has elected to recognize accrued interest (net of related tax benefits) and penalties related to uncertain tax positions as a component of its income tax expense. The Company has accrued approximately $ in penalties and interest for the . The Company remains subject to examination by federal and state authorities for the tax years 2018 through 2021 . Investment tax credits were deferred through 1986 and are recognized as a reduction of deferred income tax expense over the estimated economic useful lives of the related assets.

BUSINESS COMBINATIONS [Abstract]
BUSINESS COMBINATIONS	NOTE 14 – BUSINESS COMBINATIONS As part of the Company’s growth strategy, on January 14, 2022 Artesian Wastewater completed its agreement to acquire TESI, which provides regulated wastewater services in Delaware. Artesian Wastewater purchased all of the stock of TESI from Middlesex Water Company for $6.4 million in cash and other consideration, including, forgiveness of a $2.1 million note due from Middlesex, consisting of $3.1 million paid at closing. This acquisition more than doubled the number of wastewater customers served in Sussex County, Delaware. The TESI acquisition was approved by the DEPSC on October 27, 2021, subject to the DEPSC determining the appropriate ratemaking treatment of the acquisition price and the assets acquired in Artesian Wastewater Management’s next base rate case. The Company reflected revenue of $0.7 million for the three months ended March 31, 2022 in its condensed consolidated statement of operations related to the acquisition. The pro forma revenue for the three months ended March 31, 2022 is estimated to be approximately $0.7 million. The Company anticipates the pro forma effects of revenue for the three months ended March 31, 2022 to be approximately the same given there has not been any changes in the rates. The pro forma information is not necessarily indicative of the Company’s future results. Any pro forma effects of earnings is not practicable, as we continue to integrate TESI operations and adjust the operating cost structure as it relates to operating expenses reflective of synergies of the combined operations, and therefore would not present an accurate comparison. The table below sets forth the preliminary purchase price allocation of this acquisition as of March 31, 2022. The preliminary purchase price allocation is provisional and there could be material changes to the estimates below.

It is expected that the LIBOR rate will no longer be published for most currencies as of December 31, 2021, however, publication for USD currency should continue through June 30, 2023. LIBOR is expected to be phased out completely by June 30, 2023. As a result, it is possible that, in the future, the LIBOR rate may become unavailable or may no longer be deemed an appropriate reference rate upon which to determine the interest rate on LIBOR Rate Loans. The guidance is optional and may be elected over time as reference rate reform activities occur. In light of this eventuality, one of the banks with which we have a line of credit arrangement, currently has initiatives underway to identify new or alternative reference rates to be used in place of the LIBOR rate. The Company is evaluating the impact of the new guidance on our financial position, results of operations and cash flows.
