Description of Business and Summary of Significant Accounting Policies
Description of Business and Summary of Significant Accounting Policies	Note 1 Description of Business Genie Energy Ltd. (“Genie”), a Delaware corporation, was incorporated in January 2011. Genie, through its wholly-owned subsidiary, Genie Energy International Corporation (“GEIC”), owns 100% of Genie Retail Energy (“GRE”), and varied interest in entities within the Genie Renewables segment. In the third quarter of 2022 GRE, owns and operates retail energy providers (“REPs”), including IDT Energy, Inc. (“IDT Energy”), Residents Energy, LLC (“Residents Energy”), Town Square Energy, LLC and Town Square Energy East, LLC (collectivity, “TSE”), Southern Federal Power LLC ("Southern Power") and Mirabito Natural Gas (“Mirabito”). GRE's REPs' businesses resell electricity and natural gas to residential and small business customers primarily in the Eastern and Midwestern United States and Texas. Genie Renewables consists of 95.5% interest in Genie Solar, an integrated solar energy company that develops, constructs and operates solar energy project for commercial and industrial customers as well as its own portfolio, a 92.8% interest in CityCom Solar, a marketer of alternative products and services complimentary of our energy offerings, a 91.5% interest in Diversegy, an energy broker for commercial customers, and a 60.0% interest in Prism Solar Technology ("Prism"), a solar solutions company that is engaged in the manufacturing of solar panels, solar installation design and solar energy project management. One In the first quarter of 2023 one 2023 Discontinued operations in Finland and Sweden Prior to the third quarter of 2022 third quarter of 2022 July 2022 The Company determined that the discontinued operations in Finland and Sweden represented a strategic shift that would have a major effect on the Company's operations and financial statements. The Company accounts for these businesses as discontinued operations and accordingly, presents the results of operations and related cash flows as discontinued operations. The results of operations and related cash flows are presented as discontinued operations for all periods. Any remaining assets and liabilities of the discontinued operations are presented separately and reflected within assets and liabilities from discontinued operations in the accompanying consolidated balance sheets as of December 31, 2023 2022 In November 2022 November 9, 2022 Following the discontinuance of operations of Lumo Finland and Lumo Sweden, GRE International ceased to be a separate segment and the remaining assets and liabilities and results of continuing operations of GRE International were combined with corporate. Discontinued Operations in United Kingdom In October 2021 Following the termination of the contract with Shell, Orbit filed a petition with the High Court of Justice Business and Property of England and Wales (the “Court”) to declare Orbit insolvent based on the Insolvency Act of 1986 November 29, 2021 December 1, 2021 December 1, 2021 The Company determined that the discontinued operations of Orbit represented a strategic shift that would have a major effect on the Company's operations and financial statements. Since the appointment of the Administrators, the Company has accounted for these businesses as discontinued operations and accordingly, has presented the results of operations and related cash flows as discontinued operations. Any remaining assets and liabilities of the discontinued operations have been presented separately, and are reflected within assets and liabilities from discontinued operations in the accompanying consolidated balance sheets as of December 31, 2022 December 1, 2021 On November 21, 2023 November 28, 2023 November 28, 2023 Seasonality and Weather; Climate Change and Volatility in Pricing The weather and the seasons, among other things, affect GRE’s revenues. Weather conditions have a significant impact on the demand for natural gas used for heating and electricity used for heating and cooling. Typically, colder winters increase demand for natural gas and electricity, and hotter summers increase demand for electricity. Milder winters or summers have the opposite effect. Unseasonal temperatures in other periods may also impact demand levels. Natural gas revenues typically increase in the first quarter due to increased heating demands and electricity revenues typically increase in the third quarter due to increased air conditioning use. Approximately 48.1 39.7 2023 2022 2023 2022 In addition to the direct physical impact that climate change may have on the Company's business, financial condition and results of operations because of the effect on pricing, demand for our offerings and/or the energy supply markets, we may also be adversely impacted by other environmental factors, including: (i) technological advances designed to promote energy efficiency and limit environmental impact; (ii) increased competition from alternative energy sources; (iii) regulatory responses aimed at decreasing greenhouse gas emissions; and (iv) litigation or regulatory actions that address the environmental impact of our energy products and services. Basis of Consolidation The method of accounting applied to long-term investments, whether consolidated, equity or cost, involves an evaluation of the significant terms of each investment that explicitly grant or suggest evidence of control or influence over the operations of the investee and also includes the identification of any variable interests in which the Company is the primary beneficiary. The consolidated financial statements include the Company’s controlled subsidiaries and the variable interest entity in which the Company is the primary beneficiary (see Note 14 Equity Method Investments Investments in businesses that the Company does not control, but in which the Company has the ability to exercise significant influence over operating and financial matters, are accounted for using the equity method. The Company periodically evaluates its equity method investments for impairment due to declines considered to be other than temporary. If the Company determines that a decline in fair value is other than temporary, then a charge to earnings is recorded, and a new basis in the investment is established. Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Significant estimates affecting amounts reported or disclosed in the consolidated financial statements include revenues, marketable equity securities and other investments, accounts receivables, allowances for doubtful accounts receivable, net realizable value of inventories, valuation of intangible assets, depreciation and amortization periods for long-lived assets, valuation allowances recorded against deferred tax assets, the valuation of stock-based compensation, valuation of derivative instruments, an estimate of captive insurance liability and loss contingencies. These estimates are based on historical experience and on various other assumptions that are believed to be reasonable under the current circumstances. Actual results may differ from those estimates. Revenue Recognition Revenues from the Sale of Electricity and Natural Gas Revenue from the single performance obligation to deliver a unit of electricity and/or natural gas is recognized as the customer simultaneously receives and consumes the benefit. Variable quantities in requirements contracts are considered to be options for additional goods and services because the customer has a current contractual right to choose the amount of additional distinct goods to purchase. GRE records unbilled revenues for the estimated amount customers will be billed for services rendered from the time meters were last read to the end of the respective accounting period. The unbilled revenue is estimated each month based on available per day usage data, the number of unbilled days in the period and historical trends. Incumbent utility companies in most of the service territories in which GRE's REPs operate offer purchase of receivables, or POR, The Company recognizes the incremental costs of obtaining a contract with a customer as an asset if it expects the benefit of those costs to be longer than one to be capitalized. For GRE, the Company applies a practical expedient to expense costs as incurred for sales commissions to acquire customers as the period would have been one Revenues from Sale of Solar Panels Revenues from sales of solar panels are recognized at a point in time following the transfer of control of the solar panels to the customer, which typically occurs upon shipment or delivery depending on the terms of the underlying contracts. For sales contracts that contain multiple performance obligations, such as the shipment or delivery of solar modules, the Company allocates the transaction price to each performance obligation identified in the contract based on relative standalone selling prices, or estimates of such prices, and recognizes the related revenue as control of each individual product is transferred to the customer, in satisfaction of the corresponding performance obligations. Revenues from the sale of solar panels are included in other revenues in the consolidated statements of operations. Revenues from Solar Projects Genie Solar enters into contracts to identify, develop, and in some cases operate solar generation sites to provide solar electricit y to its customers. Obligations under solar project contracts consist of a series of tasks and components and accordingly are accounted for as multiple performance obligations. Because the Company’s performance creates and enhances assets that are controlled by and specific to customers, the Company recognizes construction services revenue over time. Revenue for these performance obligations is recognized using the input method based on the cost incurred as a percentage of total estimated contract costs. Due to the significance of the costs associated with solar panels to the total project, our judgment on when such costs should be included in the measure of progress has a material impact on revenue recognition. Contract costs include all direct material and labor costs related to contract performance. Energy generation revenue is earned from both the sale of electricity generated from solar projects and the sale of renewable energy credits. Revenue from energy generation is recognized when the Company satisfies the performance obligation, which occurs at the time of the delivery of electricity at the contractual rates. The Company applies for and receives Solar Renewable Energy Credits ("SRECs") in certain jurisdictions for power generated by solar energy systems it owns. There are no direct costs allocated to SRECs upon generation. The Company typically sells SRECs to different customers from those purchasing the energy. The sale of each SREC is a distinct performance obligation satisfied at a point in time and that the performance obligation related to each SREC is satisfied when each SREC is delivered to the customer. Revenues from sales of solar panels and solar panel projects are included under the Other Revenues in the consolidated statements of operations. Others Revenues from commissions from selling third-party products to customers, entry and other fees from energy brokerage are recognized at the time the performance obligation is met. The Company's contracts with customers for commission revenue contain a single performance obligation and are satisfied at a point in time.

These advance payments are recognized as revenue as the Company satisfies the performance obligations to the other party. A portion of the transaction price allocated to the performance obligations to be satisfied in future periods is recognized as a contract liability. Contract liabilities are included in other current liabilities account in the consolidated balance sheet. The table below reconciles the change in the carrying amount of contract liabilities: Year Ended December 31, 2023 2022 (in thousands) Contract liability, beginning $ 1,759 $ 367 Recognition of revenue included in the beginning of the year contract liability (1,336 ) (367 ) Additions during the period, net of revenue recognized during the period 5,159 1,759 Contract liability, end $ 5,582 $ 1,759 Cash, Cash Equivalents and Restricted Cash The Company considers all highly liquid investments with an original maturity of three The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported in the consolidated balance sheet that equals the total of the same amounts reported in the consolidated statement of cash flows: December 31, 2023 2022 (in thousands) Cash and cash equivalents $ 107,609 $ 98,571 Restricted cash—short-term 10,442 6,007 Restricted cash—long -term 44,945 — Total cash, cash equivalents, and restricted cash $ 162,996 $ 104,578 Restricted cash—short-term includes amounts set aside in accordance with the Amended and Restated Preferred Supplier Agreement with BP Energy Company (“BP”) (see Note 16 Note 10 Restricted cash—long -term includes cash of a wholly-owned captive insurance subsidiary (the "Captive"), which is restricted for use to secure the noncurrent portion of the insured liability program (see Note 16 December 31, 2023 Included in the cash and cash equivalents as of December 31, 2023 and 2022 see Note 2 ) Marketable Equity Securities and Other Investment Marketable equity securities that are traded in the public market are carried at fair value using the quoted price at the end of each reporting period. Changes in the fair value are recorded as unrealized gains or losses on investments in the consolidated statements of operations. Trade Accounts Receivable, Net Trade accounts receivable, net is reported in the balance sheet as gross outstanding amounts adjusted for doubtful accounts. Inventories Inventory consists of natural gas, renewable energy credits and solar panels. Natural Gas Natural gas inventory is stored at various third parties’ underground storage facilities and is stated at lower of cost or net realizable value. The Company’s natural gas inventory was valued at weighted average cost, which was based on the purchase price of the natural gas and the cost to transport, plus or minus injections or withdrawals. Renewable Energy Credits GRE must obtain a certain percentage or amount of its power supply from renewable energy sources in order to meet the requirements of renewable portfolio standards in the states in which it operates. This requirement may be met by obtaining renewable energy credits that provide evidence that electricity has been generated by a qualifying renewable facility or resource. GRE holds renewable energy credits for both sale and use, and treats the credits as a government incentive to encourage the construction of renewable power plants. Renewable energy credits are valued at the lower of cost and net realizable value. Gains and losses from the sale of renewable energy credits are recognized in cost of revenues when the credits are transferred to the buyer. Solar Panels Inventories related to solar panels are stated at the lower of cost or net realizable value. The cost is determined using the first-in, first-out basis and includes both the costs of acquisition and the costs of manufacturing. These costs include direct material, direct labor, and indirect manufacturing costs. The Company regularly reviews the cost of inventories against their estimated net realizable value and records write-downs if any inventories have costs in excess of their net realizable values. The Company also regularly evaluates the quantities and values of inventories, in light of current market conditions and trends, among other factors and records write-downs for any quantities in excess of demand or for any obsolescence. This evaluation considers the use of modules in the systems business, expected demand, anticipated sales prices, strategic raw material requirements, new product development schedules, the effect new products might have on the sale of existing products, product obsolescence, product merchantability, and other factors. Market conditions are subject to change, and actual consumption of our inventory could differ from forecasted demand. Inventories consisted of the following: December 31, 2023 2022 (in thousands) Natural gas $ 1,309 $ 3,302 Renewable credits 12,105 10,531 Solar panels, net 1,184 1,881 Total inventories $ 14,598 $ 15,714 In the year ended December 31, 2023 The change in the inventory valuation was as follows: (in thousands) Balance at beginning of period Additions charged (reversals credited) to expense Additions (deductions) Balance at end of period Year ended December 31, 2023 Reserves deducted solar panel inventories: Allowance for inventory valuation $ — $ 1,148 $ — $ 1,148 Long-lived Assets Property, plant and equipment — Asset retirement obligations consist of the Company's contractual liability for the removal and disposal cost of its solar array systems. These liabilities are recorded at their fair values (which are the present values of the estimated future cash outflows) in the period in which they are incurred, with an accompanying addition to the recorded cost of the long-lived asset. The asset retirement obligation is accreted each year through a charge to expense. The amounts added to the carrying amounts of the solar array system will be depreciated over the useful lives of the assets. The estimated useful life of property plant and equipment as follows: Years Machinery and equipment 2 — Solar array system 14 — Computer software and development 2 — Computers and computer hardware 2 — Office equipment and other 4 — The fair value of patents and trademarks, non-compete agreements and customer relationships acquired in a business combination accounted for under the purchase method are amortized over their estimated useful lives as follows: patents and trademarks are amortized on a straight-line basis over a 10 to 20-year period; non-compete agreements are amortized on a straight-line basis 9-year term and licenses are amortized on a straight-line basis over a 10-year period. The Company tests the recoverability of its long-lived assets with finite useful lives whenever events or changes in circumstances indicate that the carrying value of the asset may not be recoverable. The Company tests the recoverability based on the projected undiscounted cash flows to be derived from such asset. If the projected undiscounted future cash flows are less than the carrying value of the asset, the Company will record an impairment loss based on the excess of carrying value over fair value of the assets. The Company generally measures fair value by considering sale prices for similar assets or by discounting estimated future cash flows from such asset using an appropriate discount rate. Cash flow projections and fair value estimates require significant estimates and assumptions by management. Should the estimates and assumptions prove to be incorrect, the Company may be required to record impairments in future periods and such impairments could be material. Acquisitions Results of operations of acquired companies are included in the Company’s results of operations as of the respective acquisition dates. The purchase price of each acquisition is allocated to the net assets acquired based on estimates of their fair values at the date of the acquisition. Any purchase price in excess of these net assets is recorded as goodwill. The allocation of purchase price in certain cases may be subject to revision based on the final determination of fair values during the measurement period, which may be up to 1 For each acquisition, the Company undertakes a detailed review to identify other intangibles assets and a valuation is performed for all such identified assets. The Company uses several market participant measures to determine estimated value. This approach includes consideration of similar recent transactions, as well as utilizing discounted expected cash flow methodologies. A substantial portion of the intangible asset value that the Company acquired is the specialized know-how of the workforce, which is treated as part of goodwill and is not required to be valued separately. The majority of the value of the identifiable intangible assets acquired is derived from customer relationships, including the related customer contracts, non-compete agreements, trademarks, patents as well as licenses. If the actual results differ from the estimates, the amount recorded in the financial statements could result in a possible impairment of the intangible assets and goodwill, or require acceleration of the amortization expenses of finite-lived intangible assets. Goodwill and Indefinite Lived Intangible Assets Goodwill is the excess of the acquisition cost of businesses over the fair value of the identifiable net assets acquired. Goodwill and other indefinite-lived intangible assets are not amortized. These assets are reviewed annually (or more frequently under various conditions) for impairment using a fair value approach. The Company has 2 reportable segments with 3 underlying reporting units: GRE and Genie Renewables, which is comprised of Solar and Diversegy. The fair value of each reporting unit is estimated using discounted cash flow methodologies, as well as considering third party market value indicators. Calculating the fair value of the reporting units requires significant estimates and assumptions by management. Should the estimates and assumptions regarding the fair value of the reporting units prove to be incorrect, the Company may be required to record impairments to its goodwill in future periods and such impairments could be material. The Company performs its annual goodwill impairment test as of October 1. In reviewing goodwill for impairment, the Company has the option, for any or all of its reporting units that carry goodwill — 50 T he determination of the fair value of our reporting units is based on an income approach that utilizes discounted cash flows for each reporting 3 820 Fair Value Measurements and Disclosure Derivative Instruments and Hedging Activities The Company records its derivatives instruments at their respective fair values. The accounting for changes in the fair value (that is, gains or losses) of a derivative instrument is dependent upon whether the derivative has been designated and qualifies as part of a hedging relationship and on the type of hedging relationship. Due to the volatility of electricity and natural gas prices, GRE enters into futures contracts, swaps and put and call options as hedges against unfavorable fluctuations in market prices of electricity and natural gas and to reduce exposure from price fluctuations. The Company does not designate its derivative instruments to qualify for hedge accounting, accordingly the futures contracts, swaps and put and call options are recorded at fair value as current and noncurrent assets or liabilities and any changes in fair value are recorded in “Cost of revenues” in the consolidated statements of operations. In addition to the above, GRE utilizes forward physical delivery contracts for a portion of their purchases of electricity and natural gas, which are defined as commodity derivative contracts. Using the exemption available for qualifying contracts, GRE applies the normal purchase and normal sale accounting treatment to its forward physical delivery contracts, therefore these contracts are not adjusted to fair value. GRE also applies the normal purchase and normal sale accounting treatment to forward contracts for the physical delivery of electricity in nodal energy markets that result in locational marginal pricing charges or credits, since this does not constitute a net settlement, even when legal title to the electricity is conveyed to the ISO during transmission. Accordingly, GRE recognizes revenue from customer sales, and the related cost of revenues, at the contracted price, as electricity and natural gas is delivered to retail customers. Shipping and Handling Fees and Costs Amounts billed to customers for shipping and handling are included in revenues. Shipping, handling and freight charges were $0.1 million and a minimal December 31, 2023 2022 0.1 December 31, 2023 2022 Foreign Currency Assets and liabilities of foreign subsidiaries denominated in foreign currencies are translated to U.S. Dollars at end-of-period rates of exchange, and their monthly results of operations are translated to U.S. Dollars at the average rates of exchange for that month. Gains or losses resulting from such foreign currency translations are recorded in “Accumulated other comprehensive income” in the consolidated balance sheets. Foreign currency transaction gains and losses are reported in “Other (expense) income, net” in the consolidated statements of operations. Advertising Expense Cost of advertising for customer acquisitions is charged to selling, general and administrative expenses in the period in which it is incurred. In the years ended December 31, 2023 2022 Income Taxes The Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to temporary differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. A valuation allowance is provided when it is more likely than not that some portion or all of a deferred tax asset will not be realized. The ultimate realization of deferred tax assets depends on the generation of future taxable income during the period in which related temporary differences become deductible. The Company considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in its assessment of a valuation allowance. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date of such change. The Company uses a two 50 one The Company classifies interest and penalties on income taxes as a component of income tax expense. Contingencies The Company accrues for loss contingencies when both (a) information available prior to issuance of the financial statements indicates that it is probable that a liability had been incurred at the date of the financial statements and (b) the amount of loss can reasonably be estimated. When the Company accrues for loss contingencies and the reasonable estimate of the loss is within a range, the Company records its best estimate within the range. When no amount within the range is a better estimate than any other amount, the Company accrues the minimum amount in the range. The Company discloses an estimated possible loss or a range of loss when it is at least reasonably possible that a loss may have been incurred. Earnings Per Share Basic earnings per share is computed by dividing net income or loss attributable to all classes of common stockholders of the Company by the weighted average number of shares of all classes of common stock issued and outstanding during the applicable period. Diluted earnings per share is determined in the same manner as basic earnings per share, except that the number of shares is increased to include restricted stock still subject to risk of forfeiture and to assume exercise of potentially dilutive stock options and warrants using the treasury stock method, unless the effect of such increase is anti-dilutive. The weighted-average number of shares used in the calculation of basic and diluted earnings per share attributable to the Company’s common stockholders consists of the following: Year ended December 31, 2023 2022 (in thousands) Basic weighted-average number of shares $ 25,553 $ 25,629 Effect of dilutive securities Shares underlying stock options and warrants 63 561 Non-vested restricted Class B common stock 446 176 Diluted weighted-average number of shares $ 26,062 $ 26,366 The following shares were excluded from the diluted earnings per share computations: Year ended December 31, (in thousands) 2023 2022 Non-vested deferred stock units — 210 Non-vested deferred stock units were excluded from the basic and diluted weighted average shares outstanding calculation because the market condition for vesting of those deferred stock units was not met as of December 31, 2022 Stock-Based Compensation The Company recognizes compensation expense for grants of stock-based awards to its employees based on the estimated fair value on the grant date. Compensation cost for awards is recognized using the straight-line method over the requisite service period, which approximates the vesting period. Stock-based compensation is included in selling, general and administrative expenses. Forfeitures of equity grants are recognized as incurred. Vulnerability Due to Certain Concentrations Financial instruments that potentially subject the Company to concentration of credit risk consist principally of cash, cash equivalents, restricted cash, certificates of deposit and trade accounts receivable. The Company holds cash, cash equivalents and restricted cash at several major financial institutions, much of which exceeds FDIC insured limits. Historically, the Company has not experienced any losses due to such concentration of credit risk. The Company’s temporary cash investments policy is to limit the dollar amount of investments with any one GRE’s REPs reduce their customer credit risk by participating in purchase of receivable, or POR, programs for a majority of their receivables. In addition to providing billing and collection services, certain utility companies purchase those REPs’ receivables and assume all credit risk without recourse to those REPs for those purchased receivables. GRE’s REPs’ primary credit risk with respect to those purchased receivables is therefore nonpayment by the utility companies. Certain of the utility companies represent significant portions of the Company’s consolidated revenues and consolidated gross trade accounts receivable balance during certain period, and such concentrations increase the Company’s risk associated with nonpayment by those utility companies. The following table summarizes the percentage of consolidated trade receivable by the customer that equaled or exceeded 10.0 December 31, 2023 2022 10.0 December 31, 2023 2022 December 31, 2023 2022 Customer A 21.4 % na % Customer B na 10.2 The following table summarizes the percentage of consolidated revenues from customers that equal or exceed 10.0 revenues in the period (no other single customer accounted for more than 10.0 % of consolidated revenues in these periods): Year ended December 31, 2023 2022 Customer A 19.5 % na % Customer B na 10.1 na —less than 10.0 Allowance for Doubtful Accounts The allowance for doubtful accounts reflects the Company’s best estimate of probable losses inherent in the accounts receivable balance. The allowance is determined based on known troubled accounts, historical expe

Lumo Finland and Lumo Sweden Operations As a result of the sustained volatility in the energy markets in Europe, in July 2022 July 13, 2022 July 19, 2022 In July 2022 August 5, 2022 August 2022 The Company determined that the discontinued operations of Lumo Finland and Lumo Sweden represented a strategic shift that will have a major effect on the Company's operations and financial statements and accordingly, the results of operations and related cash flows are presented as discontinued operations for all periods presented. The assets and liabilities of the discontinued operations have been presented separately and reflected within assets and liabilities from discontinued operations in the accompanying consolidated balance sheets as of December 31, 2023 2022 On November 7, 2022 November 9, 2022 November 9, 2022 The following table represents summarized balance sheet information of assets and liabilities of the discontinued operations of Lumo Finland and Lumo Sweden: December 31, 2023 December 31, 2022 (in thousands) Assets Cash $ 2,483 $ 1,503 Receivables from the settlement of the derivative contract—current 10,699 23,351 Current assets of discontinued operations $ 13,182 $ 24,854 Receivables from the settlement of the derivative contract—noncurrent $ 2,362 $ 12,689 Other noncurrent assets 5,078 3,616 Noncurrent assets of discontinued operations $ 7,440 $ 16,305 Liabilities Income taxes payable 1,399 10,894 Accounts payable and other current liabilities 91 42 Current liabilities of discontinued operations $ 1,490 $ 10,936 Deferred tax liabilities 698 686 Noncurrent liabilities of discontinued operations $ 698 $ 686 The summary of the results of operations of the discontinued operations were as follows: Year ended December 31, 2023 2022 (in thousands) Total revenues $ — $ 25,247 Cost of revenues — (8,357 ) Gross profit — 33,604 Selling, general and administrative expenses — 5,190 Loss from operations — 28,414 Gain from the settlement of assets — 7,482 Loss from deconsolidation of subsidiary — (314 ) Foreign exchange gains — 2,241 Other income 442 383 Net income before taxes 442 38,206 Income taxes 28 7,761 Income from discontinued operations, net of taxes $ 414 $ 30,445 The following table presents a summary of cash flows of the discontinued operations: Year Ended December 31, 2023 2022 (in thousands) Operating Activities Net income $ 414 $ 30,445 Non-cash items (1,743 ) (8,370 ) Changes in assets and liabilities 12,869 (7,395 ) Cash flows used in operating activities of discontinued operation $ 11,540 $ 14,680 In furtherance of the Company’s exit from retail energy markets in Finland and Sweden and to facilitate the maximization of value at Lumo Sweden, November 3, 2022 132,302 restricted Class B common stock of the Company, which will vest ratably from November 2022 to May 2025. The Company increased its interest in Lumo Finland from % to % and in Lumo Sweden from % to %. The assets and liabilities of Lumo Finland and Lumo Sweden were included in GRE International segment. On November 8, 2023 December 31, 2023 Genie was also notified that the Administrator filed a claim against one € December 31, 2023 T € December 31, 2023 The Administrator alleges that the payments represented preferential payments and therefore belong to the bankruptcy estate which are recoverable under the laws of Finland. The Company believes that the Administrator’s position is incorrect, and intends to vigorously challenge the Administrator’s claims. Nevertheless, should the Administrator succeed in clawing back the funds from the supplier, it is possible that following the conclusion of the bankruptcy proceedings, the supplier will seek to recover its losses against the Company, under terms of the parental guarantee. At this time, there is insufficient basis to deem any loss probable or to assess the amount of any possible loss. Discontinuance of U.K. Operations In the third quarter o 2021 , the natural gas and energy market in the United Kingdom deteriorated which prompted the Company to start the process of orderly withdrawal from the U.K. market. In October 2021 Following the termination of the contract with Shell, Orbit filed a petition with the High Court of Justice Business and Property of England and Wales (the “Court”) to declare Orbit insolvent based on the Insolvency Act of 1986 November 29, 2021 December 1, 2021 In the fourth quarter of 2021, Orbit transferred to GEIC a net amount of $49.7 million from the proceeds of the settlement of the contract with Shell which is included in cash and cash equivalents in the consolidated balance sheet as of December 31, 2021. In January 2022, the Company transferred $21.5 million to the Administrators of Orbit Energy to fund the settlement of the expected remaining liabilities of Orbit of $ 30.8 . In February 20 22 On February 24, 2022, the Administrators filed a petition under Chapter 15 In the second quarter 2022 The Company determined that the discontinued operations of Orbit represented a strategic shift that would have a major effect on the Company's operations and financial statements and accordingly, the results of operations and related cash flows are presented as discontinued operations for all periods presented. December 31, 2023 As a result of loss of control, the Company deconsolidated Orbit effective December 1, 2021 and estimated the remaining liability related to its ownership of Orbit.

The underlying asset in the Company’s put and call options is a forward contract. The Company’s swaps are agreements whereby a floating (or market or spot) price is exchanged for a fixed price over a specified period. Fair Value of Other Financial Instruments The estimated fair value of the Company’s other financial instruments was determined using available market information or other appropriate valuation methodologies. However, considerable judgment is required in interpreting this data to develop estimates of fair value. Consequently, the estimates are not necessarily indicative of the amounts that could be realized or would be paid in a current market exchange.

Right-of-Use ("ROU") assets are included under other assets in the consolidated balance sheet The current portion of the operating lease liabilities are included in other current liabilities the noncurrent portion is included in ROU assets and operating lease liabilities are recognized at the present value of the future lease payments at the lease commencement date. The interest rate used to determine the present value of the future lease payments is the incremental borrowing rate, because the interest rate implicit in most of our leases is not readily determinable. The incremental borrowing rate is estimated to approximate the interest rate on a collateralized borrowing rate based on information available at the lease commencement date. ROU assets also include any prepaid lease payments and lease incentives.

Description of Business and Summary of Significant Accounting Policies
Description of Business	Description of Business Genie Energy Ltd. (“Genie”), a Delaware corporation, was incorporated in January 2011. Genie, through its wholly-owned subsidiary, Genie Energy International Corporation (“GEIC”), owns 100% of Genie Retail Energy (“GRE”), and varied interest in entities within the Genie Renewables segment. In the third quarter of 2022 GRE, owns and operates retail energy providers (“REPs”), including IDT Energy, Inc. (“IDT Energy”), Residents Energy, LLC (“Residents Energy”), Town Square Energy, LLC and Town Square Energy East, LLC (collectivity, “TSE”), Southern Federal Power LLC ("Southern Power") and Mirabito Natural Gas (“Mirabito”). GRE's REPs' businesses resell electricity and natural gas to residential and small business customers primarily in the Eastern and Midwestern United States and Texas. Genie Renewables consists of 95.5% interest in Genie Solar, an integrated solar energy company that develops, constructs and operates solar energy project for commercial and industrial customers as well as its own portfolio, a 92.8% interest in CityCom Solar, a marketer of alternative products and services complimentary of our energy offerings, a 91.5% interest in Diversegy, an energy broker for commercial customers, and a 60.0% interest in Prism Solar Technology ("Prism"), a solar solutions company that is engaged in the manufacturing of solar panels, solar installation design and solar energy project management. One In the first quarter of 2023 one 2023 Discontinued operations in Finland and Sweden Prior to the third quarter of 2022 third quarter of 2022 July 2022 The Company determined that the discontinued operations in Finland and Sweden represented a strategic shift that would have a major effect on the Company's operations and financial statements. The Company accounts for these businesses as discontinued operations and accordingly, presents the results of operations and related cash flows as discontinued operations. The results of operations and related cash flows are presented as discontinued operations for all periods. Any remaining assets and liabilities of the discontinued operations are presented separately and reflected within assets and liabilities from discontinued operations in the accompanying consolidated balance sheets as of December 31, 2023 2022 In November 2022 November 9, 2022 Following the discontinuance of operations of Lumo Finland and Lumo Sweden, GRE International ceased to be a separate segment and the remaining assets and liabilities and results of continuing operations of GRE International were combined with corporate. Discontinued Operations in United Kingdom In October 2021 Following the termination of the contract with Shell, Orbit filed a petition with the High Court of Justice Business and Property of England and Wales (the “Court”) to declare Orbit insolvent based on the Insolvency Act of 1986 November 29, 2021 December 1, 2021 December 1, 2021 The Company determined that the discontinued operations of Orbit represented a strategic shift that would have a major effect on the Company's operations and financial statements. Since the appointment of the Administrators, the Company has accounted for these businesses as discontinued operations and accordingly, has presented the results of operations and related cash flows as discontinued operations. Any remaining assets and liabilities of the discontinued operations have been presented separately, and are reflected within assets and liabilities from discontinued operations in the accompanying consolidated balance sheets as of December 31, 2022 December 1, 2021 On November 21, 2023 November 28, 2023 November 28, 2023 Seasonality and Weather; Climate Change and Volatility in Pricing The weather and the seasons, among other things, affect GRE’s revenues. Weather conditions have a significant impact on the demand for natural gas used for heating and electricity used for heating and cooling. Typically, colder winters increase demand for natural gas and electricity, and hotter summers increase demand for electricity. Milder winters or summers have the opposite effect. Unseasonal temperatures in other periods may also impact demand levels. Natural gas revenues typically increase in the first quarter due to increased heating demands and electricity revenues typically increase in the third quarter due to increased air conditioning use. Approximately 48.1 39.7 2023 2022 2023 2022 In addition to the direct physical impact that climate change may have on the Company's business, financial condition and results of operations because of the effect on pricing, demand for our offerings and/or the energy supply markets, we may also be adversely impacted by other environmental factors, including: (i) technological advances designed to promote energy efficiency and limit environmental impact; (ii) increased competition from alternative energy sources; (iii) regulatory responses aimed at decreasing greenhouse gas emissions; and (iv) litigation or regulatory actions that address the environmental impact of our energy products and services.
Basis of Consolidation	Basis of Consolidation The method of accounting applied to long-term investments, whether consolidated, equity or cost, involves an evaluation of the significant terms of each investment that explicitly grant or suggest evidence of control or influence over the operations of the investee and also includes the identification of any variable interests in which the Company is the primary beneficiary. The consolidated financial statements include the Company’s controlled subsidiaries and the variable interest entity in which the Company is the primary beneficiary (see Note 14
Equity Method Investments	Equity Method Investments Investments in businesses that the Company does not control, but in which the Company has the ability to exercise significant influence over operating and financial matters, are accounted for using the equity method. The Company periodically evaluates its equity method investments for impairment due to declines considered to be other than temporary. If the Company determines that a decline in fair value is other than temporary, then a charge to earnings is recorded, and a new basis in the investment is established.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Significant estimates affecting amounts reported or disclosed in the consolidated financial statements include revenues, marketable equity securities and other investments, accounts receivables, allowances for doubtful accounts receivable, net realizable value of inventories, valuation of intangible assets, depreciation and amortization periods for long-lived assets, valuation allowances recorded against deferred tax assets, the valuation of stock-based compensation, valuation of derivative instruments, an estimate of captive insurance liability and loss contingencies. These estimates are based on historical experience and on various other assumptions that are believed to be reasonable under the current circumstances. Actual results may differ from those estimates.
Cash, Cash Equivalents and Restricted Cash	Cash, Cash Equivalents and Restricted Cash The Company considers all highly liquid investments with an original maturity of three The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported in the consolidated balance sheet that equals the total of the same amounts reported in the consolidated statement of cash flows: December 31, 2023 2022 (in thousands) Cash and cash equivalents $ 107,609 $ 98,571 Restricted cash—short-term 10,442 6,007 Restricted cash—long -term 44,945 — Total cash, cash equivalents, and restricted cash $ 162,996 $ 104,578 Restricted cash—short-term includes amounts set aside in accordance with the Amended and Restated Preferred Supplier Agreement with BP Energy Company (“BP”) (see Note 16 Note 10 Restricted cash—long -term includes cash of a wholly-owned captive insurance subsidiary (the "Captive"), which is restricted for use to secure the noncurrent portion of the insured liability program (see Note 16 December 31, 2023 Included in the cash and cash equivalents as of December 31, 2023 and 2022 see Note 2 )
Marketable Equity Securities and Other Investment	Marketable Equity Securities and Other Investment Marketable equity securities that are traded in the public market are carried at fair value using the quoted price at the end of each reporting period. Changes in the fair value are recorded as unrealized gains or losses on investments in the consolidated statements of operations.
Trade Accounts Receivable, Net	Trade Accounts Receivable, Net Trade accounts receivable, net is reported in the balance sheet as gross outstanding amounts adjusted for doubtful accounts.
Inventories	Inventories Inventory consists of natural gas, renewable energy credits and solar panels. Natural Gas Natural gas inventory is stored at various third parties’ underground storage facilities and is stated at lower of cost or net realizable value. The Company’s natural gas inventory was valued at weighted average cost, which was based on the purchase price of the natural gas and the cost to transport, plus or minus injections or withdrawals. Renewable Energy Credits GRE must obtain a certain percentage or amount of its power supply from renewable energy sources in order to meet the requirements of renewable portfolio standards in the states in which it operates. This requirement may be met by obtaining renewable energy credits that provide evidence that electricity has been generated by a qualifying renewable facility or resource. GRE holds renewable energy credits for both sale and use, and treats the credits as a government incentive to encourage the construction of renewable power plants. Renewable energy credits are valued at the lower of cost and net realizable value. Gains and losses from the sale of renewable energy credits are recognized in cost of revenues when the credits are transferred to the buyer. Solar Panels Inventories related to solar panels are stated at the lower of cost or net realizable value. The cost is determined using the first-in, first-out basis and includes both the costs of acquisition and the costs of manufacturing. These costs include direct material, direct labor, and indirect manufacturing costs. The Company regularly reviews the cost of inventories against their estimated net realizable value and records write-downs if any inventories have costs in excess of their net realizable values. The Company also regularly evaluates the quantities and values of inventories, in light of current market conditions and trends, among other factors and records write-downs for any quantities in excess of demand or for any obsolescence. This evaluation considers the use of modules in the systems business, expected demand, anticipated sales prices, strategic raw material requirements, new product development schedules, the effect new products might have on the sale of existing products, product obsolescence, product merchantability, and other factors. Market conditions are subject to change, and actual consumption of our inventory could differ from forecasted demand. Inventories consisted of the following: December 31, 2023 2022 (in thousands) Natural gas $ 1,309 $ 3,302 Renewable credits 12,105 10,531 Solar panels, net 1,184 1,881 Total inventories $ 14,598 $ 15,714 In the year ended December 31, 2023 The change in the inventory valuation was as follows: (in thousands) Balance at beginning of period Additions charged (reversals credited) to expense Additions (deductions) Balance at end of period Year ended December 31, 2023 Reserves deducted solar panel inventories: Allowance for inventory valuation $ — $ 1,148 $ — $ 1,148
Long-lived Assets	Long-lived Assets Property, plant and equipment — Asset retirement obligations consist of the Company's contractual liability for the removal and disposal cost of its solar array systems. These liabilities are recorded at their fair values (which are the present values of the estimated future cash outflows) in the period in which they are incurred, with an accompanying addition to the recorded cost of the long-lived asset. The asset retirement obligation is accreted each year through a charge to expense. The amounts added to the carrying amounts of the solar array system will be depreciated over the useful lives of the assets. The estimated useful life of property plant and equipment as follows: Years Machinery and equipment 2 — Solar array system 14 — Computer software and development 2 — Computers and computer hardware 2 — Office equipment and other 4 — The fair value of patents and trademarks, non-compete agreements and customer relationships acquired in a business combination accounted for under the purchase method are amortized over their estimated useful lives as follows: patents and trademarks are amortized on a straight-line basis over a 10 to 20-year period; non-compete agreements are amortized on a straight-line basis 9-year term and licenses are amortized on a straight-line basis over a 10-year period. The Company tests the recoverability of its long-lived assets with finite useful lives whenever events or changes in circumstances indicate that the carrying value of the asset may not be recoverable. The Company tests the recoverability based on the projected undiscounted cash flows to be derived from such asset. If the projected undiscounted future cash flows are less than the carrying value of the asset, the Company will record an impairment loss based on the excess of carrying value over fair value of the assets. The Company generally measures fair value by considering sale prices for similar assets or by discounting estimated future cash flows from such asset using an appropriate discount rate. Cash flow projections and fair value estimates require significant estimates and assumptions by management. Should the estimates and assumptions prove to be incorrect, the Company may be required to record impairments in future periods and such impairments could be material.
Acquisitions	Acquisitions Results of operations of acquired companies are included in the Company’s results of operations as of the respective acquisition dates. The purchase price of each acquisition is allocated to the net assets acquired based on estimates of their fair values at the date of the acquisition. Any purchase price in excess of these net assets is recorded as goodwill. The allocation of purchase price in certain cases may be subject to revision based on the final determination of fair values during the measurement period, which may be up to 1 For each acquisition, the Company undertakes a detailed review to identify other intangibles assets and a valuation is performed for all such identified assets. The Company uses several market participant measures to determine estimated value. This approach includes consideration of similar recent transactions, as well as utilizing discounted expected cash flow methodologies. A substantial portion of the intangible asset value that the Company acquired is the specialized know-how of the workforce, which is treated as part of goodwill and is not required to be valued separately. The majority of the value of the identifiable intangible assets acquired is derived from customer relationships, including the related customer contracts, non-compete agreements, trademarks, patents as well as licenses. If the actual results differ from the estimates, the amount recorded in the financial statements could result in a possible impairment of the intangible assets and goodwill, or require acceleration of the amortization expenses of finite-lived intangible assets.
Goodwill and Indefinite Lived Intangible Assets	Goodwill and Indefinite Lived Intangible Assets Goodwill is the excess of the acquisition cost of businesses over the fair value of the identifiable net assets acquired. Goodwill and other indefinite-lived intangible assets are not amortized. These assets are reviewed annually (or more frequently under various conditions) for impairment using a fair value approach. The Company has 2 reportable segments with 3 underlying reporting units: GRE and Genie Renewables, which is comprised of Solar and Diversegy. The fair value of each reporting unit is estimated using discounted cash flow methodologies, as well as considering third party market value indicators. Calculating the fair value of the reporting units requires significant estimates and assumptions by management. Should the estimates and assumptions regarding the fair value of the reporting units prove to be incorrect, the Company may be required to record impairments to its goodwill in future periods and such impairments could be material. The Company performs its annual goodwill impairment test as of October 1. In reviewing goodwill for impairment, the Company has the option, for any or all of its reporting units that carry goodwill — 50 T he determination of the fair value of our reporting units is based on an income approach that utilizes discounted cash flows for each reporting 3 820 Fair Value Measurements and Disclosure
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities The Company records its derivatives instruments at their respective fair values. The accounting for changes in the fair value (that is, gains or losses) of a derivative instrument is dependent upon whether the derivative has been designated and qualifies as part of a hedging relationship and on the type of hedging relationship. Due to the volatility of electricity and natural gas prices, GRE enters into futures contracts, swaps and put and call options as hedges against unfavorable fluctuations in market prices of electricity and natural gas and to reduce exposure from price fluctuations. The Company does not designate its derivative instruments to qualify for hedge accounting, accordingly the futures contracts, swaps and put and call options are recorded at fair value as current and noncurrent assets or liabilities and any changes in fair value are recorded in “Cost of revenues” in the consolidated statements of operations. In addition to the above, GRE utilizes forward physical delivery contracts for a portion of their purchases of electricity and natural gas, which are defined as commodity derivative contracts. Using the exemption available for qualifying contracts, GRE applies the normal purchase and normal sale accounting treatment to its forward physical delivery contracts, therefore these contracts are not adjusted to fair value. GRE also applies the normal purchase and normal sale accounting treatment to forward contracts for the physical delivery of electricity in nodal energy markets that result in locational marginal pricing charges or credits, since this does not constitute a net settlement, even when legal title to the electricity is conveyed to the ISO during transmission. Accordingly, GRE recognizes revenue from customer sales, and the related cost of revenues, at the contracted price, as electricity and natural gas is delivered to retail customers.
Shipping and Handling Fees and Costs	Shipping and Handling Fees and Costs Amounts billed to customers for shipping and handling are included in revenues. Shipping, handling and freight charges were $0.1 million and a minimal December 31, 2023 2022 0.1 December 31, 2023 2022
Foreign Currency	Foreign Currency Assets and liabilities of foreign subsidiaries denominated in foreign currencies are translated to U.S. Dollars at end-of-period rates of exchange, and their monthly results of operations are translated to U.S. Dollars at the average rates of exchange for that month. Gains or losses resulting from such foreign currency translations are recorded in “Accumulated other comprehensive income” in the consolidated balance sheets. Foreign currency transaction gains and losses are reported in “Other (expense) income, net” in the consolidated statements of operations.
Advertising Expense	Advertising Expense Cost of advertising for customer acquisitions is charged to selling, general and administrative expenses in the period in which it is incurred. In the years ended December 31, 2023 2022
Income Taxes	Income Taxes The Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to temporary differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. A valuation allowance is provided when it is more likely than not that some portion or all of a deferred tax asset will not be realized. The ultimate realization of deferred tax assets depends on the generation of future taxable income during the period in which related temporary differences become deductible. The Company considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in its assessment of a valuation allowance. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date of such change. The Company uses a two 50 one The Company classifies interest and penalties on income taxes as a component of income tax expense.
Contingencies	Contingencies The Company accrues for loss contingencies when both (a) information available prior to issuance of the financial statements indicates that it is probable that a liability had been incurred at the date of the financial statements and (b) the amount of loss can reasonably be estimated. When the Company accrues for loss contingencies and the reasonable estimate of the loss is within a range, the Company records its best estimate within the range. When no amount within the range is a better estimate than any other amount, the Company accrues the minimum amount in the range. The Company discloses an estimated possible loss or a range of loss when it is at least reasonably possible that a loss may have been incurred.
Earnings Per Share	Earnings Per Share Basic earnings per share is computed by dividing net income or loss attributable to all classes of common stockholders of the Company by the weighted average number of shares of all classes of common stock issued and outstanding during the applicable period. Diluted earnings per share is determined in the same manner as basic earnings per share, except that the number of shares is increased to include restricted stock still subject to risk of forfeiture and to assume exercise of potentially dilutive stock options and warrants using the treasury stock method, unless the effect of such increase is anti-dilutive. The weighted-average number of shares used in the calculation of basic and diluted earnings per share attributable to the Company’s common stockholders consists of the following: Year ended December 31, 2023 2022 (in thousands) Basic weighted-average number of shares $ 25,553 $ 25,629 Effect of dilutive securities Shares underlying stock options and warrants 63 561 Non-vested restricted Class B common stock 446 176 Diluted weighted-average number of shares $ 26,062 $ 26,366 The following shares were excluded from the diluted earnings per share computations: Year ended December 31, (in thousands) 2023 2022 Non-vested deferred stock units — 210 Non-vested deferred stock units were excluded from the basic and diluted weighted average shares outstanding calculation because the market condition for vesting of those deferred stock units was not met as of December 31, 2022
Stock-Based Compensation	Stock-Based Compensation The Company recognizes compensation expense for grants of stock-based awards to its employees based on the estimated fair value on the grant date. Compensation cost for awards is recognized using the straight-line method over the requisite service period, which approximates the vesting period. Stock-based compensation is included in selling, general and administrative expenses. Forfeitures of equity grants are recognized as incurred.
Vulnerability Due to Certain Concentrations	Vulnerability Due to Certain Concentrations Financial instruments that potentially subject the Company to concentration of credit risk consist principally of cash, cash equivalents, restricted cash, certificates of deposit and trade accounts receivable. The Company holds cash, cash equivalents and restricted cash at several major financial institutions, much of which exceeds FDIC insured limits. Historically, the Company has not experienced any losses due to such concentration of credit risk. The Company’s temporary cash investments policy is to limit the dollar amount of investments with any one GRE’s REPs reduce their customer credit risk by participating in purchase of receivable, or POR, programs for a majority of their receivables. In addition to providing billing and collection services, certain utility companies purchase those REPs’ receivables and assume all credit risk without recourse to those REPs for those purchased receivables. GRE’s REPs’ primary credit risk with respect to those purchased receivables is therefore nonpayment by the utility companies. Certain of the utility companies represent significant portions of the Company’s consolidated revenues and consolidated gross trade accounts receivable balance during certain period, and such concentrations increase the Company’s risk associated with nonpayment by those utility companies. The following table summarizes the percentage of consolidated trade receivable by the customer that equaled or exceeded 10.0 December 31, 2023 2022 10.0 December 31, 2023 2022 December 31, 2023 2022 Customer A 21.4 % na % Customer B na 10.2 The following table summarizes the percentage of consolidated revenues from customers that equal or exceed 10.0 revenues in the period (no other single customer accounted for more than 10.0 % of consolidated revenues in these periods): Year ended December 31, 2023 2022 Customer A 19.5 % na % Customer B na 10.1 na —less than 10.0
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts The allowance for doubtful accounts reflects the Company’s best estimate of probable losses inherent in the accounts receivable balance. The allowance is determined based on known troubled accounts, historical experience and other currently available evidence. Doubtful accounts are written-off upon final determination that the trade accounts will not be collected. The change in the allowance for doubtful accounts was as follows: (in thousands) Balance at beginning of period Additions charged (reversals credited) to expense Additions (deductions) Balance at end of period Year ended December 31, 2023 Reserves deducted from accounts receivable: Allowance for doubtful accounts $ 4,826 $ 2,362 $ (614 ) $ 6,574 Year ended December 31, 2022 Reserves deducted from accounts receivable: Allowance for doubtful accounts $ 6,139 $ 2,515 $ (3,828 ) $ 4,826
Fair Value Measurements	Fair Value Measurements Fair value of financial and non-financial assets and liabilities is defined as an exit price, which is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The three Level 1 — quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 — quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 — unobservable inputs based on the Company’s assumptions used to measure assets and liabilities at fair value. A financial asset's or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the valuation of the assets and liabilities being measured and their placement within the fair value hierarchy.
Accounting Standards Updates	Accounting Standards Updates In June 2016, the FASB issued Accounting Standards Updated ("ASU") No. 2016 13 Measurement of Credit Losses on Financial Instruments In addition, an entity will have to disclose significantly more information about allowances, credit quality indicators and past due securities. The new provisions will be applied as a cumulative-effect adjustment to retained earnings.
