A discussion and analysis of fiscal year 2017 may be found in Part II,Item 7 - Management's Discussion and Analysis of Financial Condition and Resultsof Operations of the Annual Report on Form 10-K for the fiscal year endedDecember 31, 2018 .As further described in Item 15 - Note 4, Acquisitions, Discontinued Operationsand Dispositions, to the Consolidated Financial Statements, the Companydetermined in prior years that the following businesses were discontinuedoperations and recast to present their results in the corporate segment:•South Central Portfolio•NRG Yield, Inc. and its Renewables Platform•Carlsbad•GenOnExecutive SummaryNRG is an integrated power company built on dynamic retail brands with diversegeneration assets. NRG brings the power of energy to customers by producing andselling electricity and related products and services in major competitive powermarkets in theU.S. andCanada in a manner that delivers value to all of NRG'sstakeholders. The Company sells energy, services, and innovative, sustainableproducts and services directly to retail customers under the brand names NRG,Reliant,Green Mountain Energy , Stream andXOOM Energy , as well as other brandnames owned by NRG, supported by approximately 23,000 MW of generation as ofDecember 31, 2019 .Business EnvironmentThe industry dynamics and external influences affecting the Company and itsbusinesses, and the power generation and retail energy industry in 2019 and forthe future medium term include:Commodities Markets - The price of natural gas plays an important role insetting the price of electricity in many of the regions where NRGoperates. Natural gas prices are driven by variables including demand from theindustrial, residential, and electric sectors, productivity across natural gassupply basins, costs of natural gas production, changes in pipelineinfrastructure, and the financial and hedging profile of natural gas customersand producers. In 2019, the average natural gas prices at Henry Hub was 15.0%lower than in 2018.If long-term gas prices increase, the Company is likely to encounter higherrealized energy prices, leading to higher energy revenues as lower priced hedgecontracts mature and are replaced by contracts with higher gas and power prices.This impact is partially offset by the retail business, as NRG's retail grossmargins have historically decreased as natural gas prices increase.NRG's retail gross margins have historically improved as natural gas pricesdecline. This would be partially offset by lower realized energy prices, leadingto lower energy revenues as higher priced hedge contracts mature and arereplaced by contracts with lower gas and power prices. To further mitigate thisimpact, NRG may increase its percentage of coal and nuclear capacity soldforward using a variety of hedging instruments, as described under the heading"Energy-Related Commodities " in Item 15 - Note 6, Accounting for DerivativeInstruments and Hedging Activities, to the Consolidated Financial Statements. 45--------------------------------------------------------------------------------
Natural gas prices are a primary driver of coal demand. The low-priced commodityenvironment has stressed coal equities, leading coal suppliers to file forbankruptcy protection, launch debt exchanges, rationalize assets, and cutproduction. If multiple parties withdraw from the market, liquidity could bechallenged in the short term. Inventory overhang will be utilized to offsetproduction losses. Coal prices are typically affected by the price of naturalgas.Electricity Prices - The price of electricity is a key determinant of theprofitability of the Company. Many variables such as the price of differentfuels, weather, load growth and unit availability all coalesce to impact thefinal price for electricity and the Company's profitability. An increase insupply cost volatility in the competitive retail markets may result in smallercompanies choosing to exit the market, which may result in further consolidationin the competitive retail space. The following table summarizes average on-peakpower prices for each of the major markets in which NRG operates for the yearsendedDecember 31, 2019 andDecember 31, 2018 .ERCOT power prices were higherprimarily due to the continued effect of lower reserve margins as a result ofasset retirements in the region. Power prices in East region decreased for theyear endedDecember 31, 2019 as compared to the same period in 2018.

In addition, the costs associated with the development of cleaninfrastructure, such as wind and solar generating facilities, continue todecline. These factors continue to drive increases in the development of cleaninfrastructure in the markets where the Company participates, which may impactthe ability of the Company's generating facilities to participate in thosemarkets. According toERCOT, Inc. , more than 30% of 2019 energy consumption intheERCOT market was generated from carbon-free resources with wind powercontributing 20%. In addition, subsidies and incentives have contributed to theincrease in renewable power sources, and customer awareness and preferences haveshifted toward sustainable solutions. Increased demand for sustainable energyproducts from both residential and commercial customers creates opportunitiesfor diversified product offerings in competitive retail markets. 46--------------------------------------------------------------------------------
Digitization and Customization - The electric industry is experiencing majortechnology changes in the way power is distributed and used by end-usecustomers. The electric grid is shifting from a centralized analog system, wherepower is generated from limited sources and flows in one direction, to adecentralized multidirectional system, where power can be generated from anumber of distributed resources and stored or dispatched on an as-needed basis.In addition, customers are seeking new ways to engage with their powerproviders. Technologies like smart thermostats, appliances and electric vehiclesare giving individuals more choice and control over their electricity usage.Weather - Weather conditions in the regions of theU.S. in which NRG doesbusiness influence the Company's financial results. Weather conditions canaffect the supply and demand for electricity and fuels and may also impact theavailability of the Company's generating assets. Changes in energy supply anddemand may impact the price of these energy commodities in both the spot andforward markets, which may affect the Company's results in any given period.Typically, demand for and the price of electricity is higher in the summer andthe winter seasons, when temperatures are more extreme. The demand for and priceof natural gas is also generally higher in the winter. However, all regions oftheU.S. typically do not experience extreme weather conditions at the sametime, thus NRG's operations are typically not exposed to the effects of extremeweather in all parts of its business at once. A significant portion of theCompany's business is located withinTexas , and extreme weather conditionsoccurring inTexas may have a material impact on the Company's financialposition.Other Factors - A number of other factors significantly influence the level andvolatility of prices for energy commodities and related derivative products forNRG's business. These factors include:•seasonal, daily and hourly changes in demand;•extreme peak demands;•available supply resources;•transportation and transmission availability and reliability within and betweenregions;•location of NRG's generating facilities relative to the location of itsload-serving opportunities;•procedures used to maintain the integrity of the physical electricity systemduring extreme conditions; and•changes in the nature and extent of federal and state regulations.These factors can affect energy commodity and derivative prices in differentways and to different degrees. These effects may vary throughout the country asa result of regional differences in:•weather conditions;•market liquidity;•capability and reliability of the physical electricity and gas systems;•local transportation systems; and•the nature and extent of electricity deregulation.Environmental Matters, Regulatory Matters and Legal Proceedings - Details ofenvironmental matters are presented in Item 15 - Note 25, Environmental Matters,to the Consolidated Financial Statements and Item 1- Business, EnvironmentalMatters.

Economic Gross MarginIn addition to gross margin, the Company evaluates its operating performanceusing the measure of economic gross margin, which is not a GAAP measure and maynot be comparable to other companies' presentations or deemed more useful thanthe GAAP information provided elsewhere in this report. Economic gross marginshould be viewed as a supplement to and not a substitute for the Company'spresentation of gross margin, which is the most directly comparable GAAPmeasure. Economic gross margin is not intended to represent gross margin. TheCompany believes that economic gross margin is useful to investors as it is akey operational measure reviewed by the Company's chief operating decisionmaker. Economic gross margin is defined as the sum of energy revenue, capacityrevenue and other revenue, less cost of fuels and other cost of sales. Economicgross margin does not include mark-to-market gains or losses on economic hedgingactivities, contract amortization, emission credit amortization, or otheroperating costs.The tables below present the composition and reconciliation of gross margin andeconomic gross margin for the years endedDecember 31, 2019 and 2018 based onthe Company's reporting segments as ofDecember 31, 2019 :

These liquidity requirements are primarilydriven by: (i) margin and collateral posted with counterparties; (ii) margin andcollateral required to participate in physical markets and commodity exchanges;(iii) timing of disbursem*nts and receipts (e.g. buying fuel before receivingenergy revenues); (iv) initial collateral for large structured transactions; and(v) collateral for project development. As ofDecember 31, 2019 , commercialoperations had total cash collateral outstanding of$190 million and$694million outstanding in letters of credit to third parties primarily to supportit* commercial activities for both wholesale and retail transactions. As ofDecember 31, 2019 , total funds deposited by counterparties was$32 million incash and$102 million of letters of credit.Future liquidity requirements may change based on the Company's hedgingactivities and structures, power purchases and sales, fuel purchases, and futuremarket conditions, including forward prices for energy and fuel and marketvolatility. In addition, liquidity requirements are dependent on the Company'scredit ratings and general perception of its creditworthiness.First Lien StructureNRG has granted first liens to certain counterparties on a substantial portionof property and assets owned by NRG and the guarantors of its senior debt. NRGuses the first lien structure to reduce the amount of cash collateral andletters of credit that it would otherwise be required to post from time to timeto support its obligations under out-of-the-money hedge agreements for forwardsales of power or gas used as a proxy for power. To the extent that theunderlying hedge positions for a counterparty are out-of-the-money to NRG, thecounterparty would have a claim under the first lien program. The first lienprogram limits the volume that can be hedged, not the value of underlyingout-of-the-money positions. The first lien program does not require NRG to postcollateral above any threshold amount of exposure. Within the first lienstructure, the Company can hedge up to 80% of its coal and nuclear capacity and10% of its other assets with these counterparties for the first 60 months andthen declining thereafter. Net exposure to a counterparty on all trades must bepositively correlated to the price of the relevant commodity for the first liento be available to that counterparty. The first lien structure is not subject tounwind or termination upon a ratings downgrade of a counterparty and has nostated maturity date.The Company's first lien counterparties may have a claim on its assets to theextent market prices exceed the hedged prices. As ofDecember 31, 2019 , allhedges under the first liens were in-the-money on a counterparty aggregatebasis. 62--------------------------------------------------------------------------------

For the year endedDecember 31, 2019 , the Company utilized NOLs of$593 million due to current yeartaxable income. As ofDecember 31, 2019 , the Company has cumulativeU.S. federalNOL carryforwards of$10.1 billion , which will begin expiring in 2031 andcumulative state NOL carryforwards of$5.5 billion . NRG also has cumulativeforeign NOL carryforwards of$357 million , which do not have an expiration date.In addition to the above NOLs, NRG has a$361 million indefinite carryforwardfor interest deductions, as well as$384 million of tax credits to be utilizedin future years. As a result of the Company's tax position, including theutilization of federal and state NOLs, and based on current forecasts, theCompany anticipates income tax payments, primarily due to state and localjurisdictions, of up to$16 million in 2020. See Item 15 - Note 20, IncomeTaxes, for further discussion regarding the release of the valuation allowance.The Company has recorded as ofDecember 31, 2019 short-term and long-termreceivables of$35 million and$34 million , respectively, representingrefundable AMT credits from theIRS , which are anticipated to be received from2020 through 2022 pursuant to the 50% annual limitation as enacted by the TaxAct upon repeal of corporate AMT effectiveJanuary 1, 2018 . Of these amounts,short-term and long-term payables of$11 million each are due to GenOn for theirshare of the minimum tax credits.In addition to these amounts, the Company has$15 million of tax effecteduncertain state tax benefits for which the Company has recorded a non-currenttax liability of$17 million (including accrued interest) until such finalresolution with the related taxing authority.The Company is no longer subject toU.S. federal income tax examinations foryears prior to 2016. With few exceptions, state and local income taxexaminations are no longer open for years before 2011. 66--------------------------------------------------------------------------------
Off-Balance Sheet ArrangementsObligations under Certain Guarantee ContractsNRG and certain of its subsidiaries enter into guarantee arrangements in thenormal course of business to facilitate commercial transactions with thirdparties. These arrangements include financial and performance guarantees,stand-by letters of credit, debt guarantees, surety bonds and indemnifications.See also Item 15 - Note 27, Guarantees, to the Consolidated Financial Statementsfor additional discussion.Retained or Contingent InterestsNRG does not have any material retained or contingent interests in assetstransferred to an unconsolidated entity.Obligations Arising Out of a Variable Interest in an Unconsolidated EntityVariable interest in Equity investments - As ofDecember 31, 2019 , NRG hasseveral investments with an ownership interest percentage of 50% or less inenergy and energy-related entities that are accounted for under the equitymethod of accounting. Ivanpah is considered a variable interest entity for whichNRG is not the primary beneficiary.NRG's pro-rata share of non-recourse debt held by unconsolidated affiliates wasapproximately$866 million as ofDecember 31, 2019 . This indebtedness mayrestrict the ability of these subsidiaries to issue dividends or distributionsto NRG.

Fair Value of Derivative InstrumentsNRG may enter into power purchase and sales contracts, fuel purchase contractsand other energy-related financial instruments to mitigate variability inearnings due to fluctuations in spot market prices and to hedge fuelrequirements at power plants or retail load obligations.NRG's trading activities are subject to limits in accordance with the Company'sRisk Management Policy. These contracts are recognized on the balance sheet atfair value and changes in the fair value of these derivative financialinstruments are recognized in earnings.The tables below disclose the activities that include both exchange andnon-exchange traded contracts accounted for at fair value in accordance with ASC820, Fair Value Measurements and Disclosures, or ASC 820. Specifically, thesetables disaggregate realized and unrealized changes in fair value; disaggregateestimated fair values atDecember 31, 2019 , based on their level within the fairvalue hierarchy defined in ASC 820; and indicate the maturities of contracts atDecember 31, 2019 . For a full discussion of the Company's valuation methodologyof its contracts, see Derivative Fair Value Measurements in Item 15 - Note 5,Fair Value of Financial Instruments, to the Consolidated Financial Statements.Derivative Activity Gains/(Losses) (In millions)Fair value of contracts as of December 31, 2018$ 104 Contracts realized or otherwise settled during the period (105)Contracts acquired during the period (12)Changes in fair value 80Fair value of contracts as of December 31, 2019 $ 67 Fair Value of Contracts as of December 31, 2019(In millions) Maturity Greater Than 1 Greater Than 3 Greater Than Total FairFair value hierarchy (Losses)/Gains 1 Year or Less Year to 3 Years Years to 5 Years 5 Years ValueLevel 1$ (31) $ (27) $ (2)$ 1 $ (59) Level 2 56 49 (7) (10) 88Level 3 54 (2) 1 (15) 38Total $ 79$ 20 $ (8)$ (24) $ 67 The Company has elected to disclose derivative assets and liabilities on atrade-by-trade basis and does not offset amounts at the counterparty masteragreement level. Also, collateral received or posted on the Company's derivativeassets or liabilities are recorded on a separate line item on the balance sheet.Consequently, the magnitude of the changes in individual current and non-currentderivative assets or liabilities is higher than the underlying credit and marketrisk of the Company's portfolio. As discussed in Item 7A - Quantitative andQualitative Disclosures About Market Risk, Commodity Price Risk, NRG measuresthe sensitivity of the Company's portfolio to potential changes in market pricesusing VaR, a statistical model which attempts to predict risk of loss based onmarket price and volatility. NRG's risk management policy places a limit onone-day holding period VaR, which limits the Company's net open position. As theCompany's trade-by-trade derivative accounting results in a gross-up of theCompany's derivative assets and liabilities, the net derivative assets andliability position is a better indicator of NRG's hedging activity. As ofDecember 31, 2019 , NRG's net derivative asset was$67 million , a decrease tototal fair value of$37 million as compared toDecember 31, 2018 . This decreasewas primarily driven by losses in trades settled and contracts acquired duringthe period, partially offset by increases in change in fair value during theperiod.Based on a sensitivity analysis using simplified assumptions, the impact of a$0.50 per MMBtu increase in natural gas prices across the term of the derivativecontracts would result in an increase of approximately$41 million in the netvalue of derivatives as ofDecember 31, 2019 .The impact of a$0.50 per MMBtu decrease in natural gas prices across the termof the derivative contracts would result in a decrease of approximately$36million in the net value of derivatives as ofDecember 31, 2019 . 68--------------------------------------------------------------------------------
Critical Accounting Policies and EstimatesNRG's discussion and analysis of the financial condition and results ofoperations are based upon the Consolidated Financial Statements, which have beenprepared in accordance with GAAP. The preparation of these financial statementsand related disclosures in compliance with GAAP requires the application ofappropriate technical accounting rules and guidance as well as the use ofestimates and judgments that affect the reported amounts of assets, liabilities,revenues and expenses, and related disclosures of contingent assets andliabilities. The application of these policies involves judgments regardingfuture events, including the likelihood of success of particular projects, legaland regulatory challenges, and the fair value of certain assets and liabilities.These judgments, in and of themselves, could materially affect the financialstatements and disclosures based on varying assumptions, which may beappropriate to use. In addition, the financial and operating environment mayalso have a significant effect, not only on the operation of the business, buton the results reported through the application of accounting measures used inpreparing the financial statements and related disclosures, even if the natureof the accounting policies have not changed.On an ongoing basis, NRG evaluates these estimates, utilizing historicexperience, consultation with experts and other methods the Company considersreasonable. In any event, actual results may differ substantially from theCompany's estimates. Any effects on the Company's business, financial positionor results of operations resulting from revisions to these estimates arerecorded in the period in which the information that gives rise to the revisionbecomes known.NRG's significant accounting policies are summarized in Item 15 - Note 2,Summary of Significant Accounting Policies, to the Consolidated FinancialStatements. The Company identifies its most critical accounting policies asthose that are the most pervasive and important to the portrayal of theCompany's financial position and results of operations, and require the mostdifficult, subjective and/or complex judgments by management regarding estimatesabout matters that are inherently uncertain.Accounting Policy Judgments/Uncertainties Affecting ApplicationDerivative Instruments Assumptions used in valuation techniques Assumptions used in forecasting generation Assumptions used in forecasting borrowings Market maturity and economic conditions Contract interpretation Market conditions in

Derivative InstrumentsThe Company follows the guidance of ASC 815 to account for derivativeinstruments. ASC 815 requires the Company to mark-to-market all derivativeinstruments on the balance sheet and recognize changes in the fair value ofnon-hedge derivative instruments immediately in earnings. In certain cases, NRGmay apply hedge accounting to the Company's derivative instruments. The criteriaused to determine if hedge accounting treatment is appropriate are: (i) thedesignation of the hedge to an underlying exposure; (ii) whether the overallrisk is being reduced; and (iii) if there is a correlation between the changesin fair value of the derivative instrument and the underlying hedged item.Changes in the fair value of derivatives instruments accounted for as hedges aredeferred and recorded as a component of OCI and subsequently recognized inearnings when the hedged transactions occur.For purposes of measuring the fair value of derivative instruments, NRG usesquoted exchange prices and broker quotes. When external prices are notavailable, NRG uses internal models to determine the fair value. These internalmodels include assumptions of the future prices of energy commodities based onthe specific market in which the energy commodity is being purchased or sold,using externally available forward market pricing curves for all periodspossible under the pricing model. These estimations are considered to becritical accounting estimates.Upon repayment of the Term Loan in 2019, all of the Company's interest rateswaps were terminated. In order to qualify the derivative instruments for hedgedtransactions prior to termination, NRG estimated the forecasted borrowings forinterest rate swaps occurring within a specified time period. Judgments relatedto the probability of forecasted borrowings were based on the estimated timingof project construction, which can vary based on various factors. Theprobability that forecasted borrowings will occur by the end of a specified timeperiod could change the results of operations by requiring amounts currentlyclassified in OCI to be reclassified into earnings, creating increasedvariability in the Company's earnings.Certain derivative instruments that meet the criteria for derivative accountingtreatment also qualify for a scope exception to derivative accounting, as theyare considered to be NPNS. The availability of this exception is based upon theassumption that NRG has the ability and it is probable to deliver or takedelivery of the underlying item. These assumptions are based on expected loadrequirements, available baseload capacity, internal forecasts of sales andgeneration and historical physical delivery on contracts. Derivatives that areconsidered to be NPNS are exempt from derivative accounting treatment and areaccounted for under accrual accounting. If it is determined that a transactiondesignated as NPNS no longer meets the scope exception due to changes inestimates, the related contract would be recorded on the balance sheet at fairvalue combined with the immediate recognition through earnings.Income Taxes and Valuation Allowance for Deferred Tax AssetsAs ofDecember 31, 2019 , NRG's deferred tax assets were primarily the result ofU.S. federal and state NOLs, the difference between book and tax basis inproperty, plant, and equipment, and tax credit carryforwards. The realization ofdeferred tax assets is dependent upon the Company's ability to generatesufficient future taxable income during the periods in which those temporarydifferences become deductible, prior to the expiration of the tax attributes.The evaluation of deferred tax assets requires judgment in assessing the likelyfuture tax consequences of events that have been recognized in the Company'sfinancial statements or tax returns and forecasting future profitability by taxjurisdiction.A valuation allowance of$242 million and$3.8 billion was recorded againstNRG's gross deferred tax asset balance as ofDecember 31, 2019 , andDecember 31,2018 , respectively. During the year endedDecember 31, 2019 , NRG released themajority of its valuation allowance against itsU.S. federal and state deferredtax assets, resulting in a non-cash benefit to income tax expense ofapproximately$3.5 billion .The Company evaluates its deferred tax assets quarterly on a jurisdictionalbasis to determine whether adjustments to the valuation allowance areappropriate considering changes in facts or circ*mstances. As of each reportingdate, management considers new evidence, both positive and negative, whendetermining the future realization of the Company's deferred tax assets. Inmaking the determination to release the majority of the valuation allowance asofDecember 31, 2019 , the Company evaluated a number of factors, including itsrecent history of pre-tax earnings, utilization of$593 million of NOLs in 2019,as well as its forecasted future pre-tax earnings. Based on this evaluation, theCompany determined that its futureU.S. federal tax benefits aremore-likely-than-not to be realized. Given the Company's current level ofpre-tax earnings and forecasted future pre-tax earnings, the Company expects togenerate income before taxes in theU.S. in future periods at a level that wouldfully utilize itsU.S. federal NOL carryforwards and the majority of its stateNOL carryforwards prior to their expiration.NRG continues to maintain a valuation allowance of approximately$242 million asofDecember 31, 2019 against net deferred tax assets consisting of state netoperating losses and foreign NOL carryforwards in jurisdictions where theCompany does not currently believe that the realization of its deferred taxassets is more likely than not.NRG continues to be under audit for multiple years by taxing authorities inother jurisdictions. Considerable judgment is required to determine the taxtreatment of a particular item that involves interpretations of complex taxlaws, including the 70--------------------------------------------------------------------------------
impact of the Tax Act effectiveDecember 22, 2017 . NRG is subject to examinationby taxing authorities for income tax returns filed in theU.S. federaljurisdiction and various state and foreign jurisdictions, including operationslocated inAustralia .The Company is no longer subject toU.S. federal income tax examinations foryears prior to 2016. With few exceptions, state and local income taxexaminations are no longer open for years before 2011.Evaluation of Assets for Impairment and Other-Than-Temporary Decline in ValueIn accordance with ASC 360, Property, Plant, and Equipment, or ASC 360, NRGevaluates property, plant and equipment and certain intangible assets forimpairment whenever indicators of impairment exist. Examples of such indicatorsor events are:•Significant decrease in the market price of a long-lived asset;•Significant adverse change in the manner an asset is being used or its physicalcondition;•Adverse business climate;•Accumulation of costs significantly in excess of the amount originally expectedfor the construction or acquisition of an asset;•Current period loss combined with a history of losses or the projection offuture losses; and•Change in the Company's intent about an asset from an intent to hold to agreater than 50% likelihood that an asset will be sold, or disposed of beforethe end of its previously estimated useful life.Recoverability of assets to be held and used is measured by a comparison of thecarrying amount of the assets to the future net cash flows expected to begenerated by the asset, through considering project specific assumptions forlong-term power prices, escalated future project operating costs and expectedplant operations. If such assets are considered to be impaired, the impairmentto be recognized is measured by the amount by which the carrying amount of theassets exceeds the fair value of the assets by factoring in the differentcourses of action available to the Company. Generally, fair value will bedetermined using valuation techniques, such as the present value of expectedfuture cash flows. NRG uses its best estimates in making these evaluations andconsiders various factors, including forward price curves for energy, fuel andoperating costs. However, actual future market prices and project costs couldvary from the assumptions used in the Company's estimates and the impact of suchvariations could be material.For assets to be held and used, if the Company determines that the undiscountedcash flows from the asset are less than the carrying amount of the asset, NRGmust estimate fair value to determine the amount of any impairment loss. Assetsheld-for-sale are reported at the lower of the carrying amount or fair valueless the cost to sell. The estimation of fair value, whether in conjunction withan asset to be held and used or with an asset held-for-sale, and the evaluationof asset impairment are, by their nature, subjective. NRG considers quotedmarket prices in active markets to the extent they are available. In the absenceof such information, the Company may consider prices of similar assets, consultwith brokers, or employ other valuation techniques. NRG will also discount theestimated future cash flows associated with the asset using a single interestrate representative of the risk involved with such an investment or employ anexpected present value method that probability-weights a range of possibleoutcomes. The use of these methods involves the same inherent uncertainty offuture cash flows as previously discussed with respect to undiscounted cashflows. Actual future market prices and project costs could vary from those usedin the Company's estimates and the impact of such variations could be material.Annually, during the fourth quarter, the Company revises its views of power andfuel prices including the Company's fundamental view for long-term prices,forecasted generation and operating and capital expenditures, in connection withthe preparation of its annual budget. Changes to the Company's views oflong-term power and fuel prices impact the Company's projections ofprofitability, based on management's estimate of supply and demand within thesub-markets for its operations and the physical and economic characteristics ofeach of its businesses.As ofDecember 31, 2019 , the Company recorded impairment losses of approximately$5 million , excluding impairment losses on equity and cost method investmentsdiscussed below. These impairment losses were primarily to record the value ofcertain long-lived assets, including property, plant and equipment andintangible assets, at fair market value in connection with an impairmentindicator.Equity and Cost Method InvestmentsNRG is also required to evaluate its equity method and cost method investmentsto determine whether or not they are impaired in accordance with ASC 323,Investments -Equity Method and Joint Ventures , or ASC 323. The standard fordetermining whether an impairment must be recorded under ASC 323 is whether adecline in the value is considered an other-than-temporary decline in value. Theevaluation and measurement of impairments under ASC 323 involves the sameuncertainties as described for long-lived assets that the Company owns directlyand accounts for in accordance with ASC 360. 71--------------------------------------------------------------------------------
Similarly, the estimates that NRG makes with respect to its equity and costmethod investments are subjective, and the impact of variations in theseestimates could be material. Additionally, if the projects in which the Companyholds these investments recognize an impairment under the provisions of ASC 360,NRG would record its proportionate share of that impairment loss and wouldevaluate its investment for an other-than-temporary decline in value under ASC323. During the year endedDecember 31, 2019 , the Company recorded impairmentlosses on its equity and cost method investments, primarilyPetra Nova , of$108 million due to declines in value.Goodwill and Other Intangible AssetsAtDecember 31, 2019 , NRG reported goodwill of$579 million , consisting of$165million associated with the acquisition of Midwest Generation and$414 million for retail business acquisitions, includingTexas non-commodity, XOOM and StreamEnergy.The Company applies ASC 805, Business Combinations, or ASC 805, and ASC 350, toaccount for its goodwill and intangible assets. Under these standards, theCompany amortizes all finite-lived intangible assets over their respectiveestimated weighted-average useful lives, while goodwill has an indefinite lifeand is not amortized.Goodwill is tested for impairment at least annually, ormore frequently whenever an event or change in circ*mstances occurs that wouldmore likely than not reduce the fair value of a reporting unit below itscarrying amount. The Company tests goodwill for impairment at the reporting unitlevel, which is identified by assessing whether the components of the Company'soperating segments constitute businesses for which discrete financialinformation is available and whether segment management regularly reviews theoperating results of those components. The Company performs the annual goodwillimpairment assessment as ofDecember 31 or when events or changes incirc*mstances indicate that the carrying value may not be recoverable. TheCompany first assesses qualitative factors to determine whether it is morelikely than not that an impairment has occurred. In the absence of sufficientqualitative factors, the Company performs a quantitative assessment bydetermining the fair value of the reporting unit and comparing to its bookvalue. If it is determined that the fair value of a reporting unit is below itscarrying amount, where necessary, the Company's goodwill will be impaired atthat time.The Company performed its qualitative assessment of macroeconomic, industry andmarket events and circ*mstances, and the overall financial performance of theNRG Business Solutions and Retail Mass reporting units. The Company determinedit was more-likely-than-not that the fair value of the goodwill attributed tothese reporting units were more than their carrying amount and accordingly, noimpairment existed for the year endedDecember 31, 2019 .The Company performed a quantitative assessment for the reporting units in thefollowing table. The Company determined the fair value of these reporting unitsusing primarily an income approach. Under the income approach, the Companyestimated the fair value of the reporting units' invested capital exceeds itscarrying value and, as such, the Company concluded that goodwill associated withthe reporting units in the following table is not impaired as ofDecember 31,2019 :Reporting Unit % Fair Value Over Carrying
Value
Midwest Generation (Generation Segment) 112 %Texas Non-Commodity (Retail Segment)
140 %
The Company believes the methodology and assumptions used in its quantitativeassessment are consistent with the views of market participants. Significantinputs to the determination of fair value were as follows:•The Company applied a discounted cash flow methodology to the long-termforecasts for the Midwest Generation plants. The significant assumptions used toderive the long-term budgets used in the income approach are affected by thefollowing key inputs:•The Company's views of power and fuel prices consider market prices for thenext five years and the Company's fundamental view for the longer term, drivenby the Company's long-term view of the price of natural gas. The Company'sfundamental view for the longer term reflects the implied power price and heatrate that would support new build of a combined cycle gas plant. The price ofnatural gas plays an important role in setting the price of electricity in manyof the regions where NRG operates power plants. Hedging is included to theextent of contracts already in place;•The Company's estimate of generation, fuel costs, capital expenditurerequirements and the existing and anticipated impact of environmentalregulations;•The Company's fundamental view for the longer term, cash flows for the plantsin the region were included in the fair value calculation through the end ofeach plants' estimated useful life; and•Projected generation and resulting energy gross margin in the long-termforecasts is based on an hourly dispatch that simulates dispatch of each unitinto the power market. The dispatch simulation is based on power prices, fuelprices, and the physical and economic characteristics of each plant 72--------------------------------------------------------------------------------
•The Company applied a discounted cash flow methodology to the long-term budgetfor the Texas Non-Commodity reporting unit. The significant assumptions used toderive the long-term budgets used in the income approach are affected by thefollowing key inputs: a terminal value utilizing assumed growth rates anddiscount rates that reflect the inherent cash flow risk.Fair value determinations require considerable judgment and are sensitive tochanges in underlying assumptions and factors. As a result, there can be noassurance that the estimates and assumptions made for purposes of the annualgoodwill impairment test will prove to be accurate predictions of the future.ContingenciesNRG records reserves for estimated losses from contingencies when informationavailable indicates that a loss is probable and the amount of the loss, or rangeof loss, can be reasonably estimated. Gain contingencies are not recorded untilmanagement determines it is certain that the future event will become or doesbecome a reality. Such determinations are subject to interpretations of currentfacts and circ*mstances, forecasts of future events, and estimates of thefinancial impacts of such events. NRG describes in detail its contingencies inItem 15 - Note 23, Commitments and Contingencies, to the Consolidated FinancialStatements.Recent Accounting DevelopmentsSee Item 15 - Note 2, Summary of Significant Accounting Policies, to theConsolidated Financial Statements for a discussion of recent accountingdevelopments. 73
