NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Note 1 — Nature of Business
NRG Yield, Inc., or the Company, is a dividend growth-oriented company formed as a Delaware corporation on December 20, 2012, to serve as the primary vehicle through which NRG owns, operates and acquires contracted renewable and conventional generation and thermal infrastructure assets.
The Company used the net proceeds from its initial public offering of Class A common stock on July 22, 2013 to acquire 100% of the Class A units of NRG Yield LLC, including a controlling interest through its position as managing member. NRG Yield LLC, through its wholly owned subsidiary, NRG Yield Operating LLC, is a holder of a portfolio of contracted renewable and conventional generation and thermal infrastructure assets, primarily located in the Northeast, Southwest and California regions of the U.S.
On July 29, 2014, the Company issued additional shares of Class A common stock and utilized the proceeds of the offering to acquire additional Class A units of NRG Yield LLC increasing its ownership to 44.7%. As of March 31, 2015, the Company continues to own 44.7% of NRG Yield LLC, and consolidates the results of NRG Yield LLC through its controlling interest, with NRG's 55.3% interest shown as noncontrolling interest in the financial statements.

Substantially all of the Company's generation assets are under long-term contractual arrangements for the output or capacity from these assets. The thermal assets are comprised of district energy systems and combined heat and power plants that produce steam, hot water and/or chilled water and in some instances, electricity at a central plant. Three of the district energy systems are subject to rate regulation by state public utility commissions while the other district energy systems have rates determined by negotiated bilateral contracts.
In connection with the initial public offering, the Company entered into a management services agreement with NRG for various services, including human resources, accounting, tax, legal, information systems, treasury, and risk management. Costs incurred by the Company under this agreement were $3 million and $2 million for the three months ended March 31, 2015, and 2014, respectively, which included certain direct expenses incurred by NRG on behalf of the Company.
Stockholders' equity represents the equity associated with the Class A common stockholders, with the equity associated with the Class B common stockholders, or NRG, classified as noncontrolling interest.
As described in Note 3, Business Acquisitions, on June 30, 2014, NRG Yield Operating LLC acquired the TA High Desert, Kansas South, and El Segundo projects from NRG for total cash consideration of $357 million plus assumed project level debt. Additionally, on January 2, 2015, NRG Yield Operating LLC acquired the Laredo Ridge, Tapestry, and Walnut Creek projects for total cash consideration of $489 million, including $9 million for working capital, plus assumed debt of $737 million. These acquisitions were accounted for as transfers of entities under common control. The guidance requires retrospective combination of the entities for all periods presented as if the combination has been in effect since the inception of common control. Accordingly, the Company prepared its consolidated financial statements to reflect the transfer as if it had taken place from the beginning of the financial statements period, or from the date the entities were under common control, which was May 13, 2013, for Kansas South, March 28, 2013, for TA High Desert, and April 1, 2014, for Laredo Ridge, the Tapestry projects and Walnut Creek, which represent the dates these entities were acquired by NRG.
The accompanying unaudited interim consolidated financial statements have been prepared in accordance with the Securities and Exchange Commission’s, or SEC’s, regulations for interim financial information. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. The following notes should be read in conjunction with the accounting policies and other disclosures as set forth in the notes to the Company’s annual financial statements for the year ended December 31, 2014. Interim results are not necessarily indicative of results for a full year.
In the opinion of management, the accompanying unaudited interim consolidated financial statements contain all material adjustments consisting of normal and recurring accruals necessary to present fairly the Company's consolidated financial position as of March 31, 2015, and the results of operations, comprehensive income and cash flows for the three months ended March 31, 2015, and 2014.
Note 2 — Summary of Significant Accounting Policies 
Use of Estimates
The preparation of consolidated financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions. These estimates and assumptions impact the reported amount of assets and liabilities and disclosures of contingent assets and liabilities as of the date of the consolidated financial statements. They also impact the reported amount of net earnings during the reporting period. Actual results could be different from these estimates.
Noncontrolling Interest
The following table reflects the changes in the Company's noncontrolling interest balance:

On January 2, 2015, the Company acquired the Laredo Ridge, Tapestry, and Walnut Creek projects, as discussed in Note 3, Business Acquisitions . The difference between the cash paid and historical value of entities' net assets of $61 million, as well as $23 million of AOCL, were recorded as a distribution to NRG and reduced the balance of its noncontrolling interest. In addition, as the Laredo Ridge, Tapestry, and Walnut Creek projects were owned by NRG until January 2, 2015, the pre-acquisition earnings of such projects are recorded as attributable to NRG's noncontrolling interest.
Distributions
On February 17, 2015, NRG Yield LLC declared a distribution on its Class A and Class B units of $0.39 per unit, which was paid on March 16, 2015. The portion of the distributions paid by NRG Yield LLC to NRG was recorded as a reduction to the Company's noncontrolling interest balance.
Recent Accounting Developments
ASU 2015-03 — In April 2015, the FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs , or ASU No. 2015-03.  The amendments of ASU No. 2015-03 were issued to reduce complexity in the balance sheet presentation of debt issuance costs.  ASU No. 2015-03 requires that debt issuance costs be presented in the balance sheet as a direct deduction from the carrying amount of debt liability, consistent with debt discounts or premiums.  The recognition and measurement guidance for debt issuance costs are not affected by the amendments in this standard.  The guidance in ASU No. 2015-03 is effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years.  Early adoption is permitted for financial statements that have not been previously issued.  The adoption of this standard is not expected to have a material impact on the Company's balance sheets on a gross basis and will have no impact on net assets.

ASU 2015-02 — In February 2015, the FASB issued ASU No. 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis , or ASU No. 2015-02. The amendments of ASU No. 2015-02 were issued in an effort to minimize situations under previously existing guidance in which a reporting entity was required to consolidate another legal entity in which that reporting entity did not have: (1) the ability through contractual rights to act primarily on its own behalf; (2) ownership of the majority of the legal entity's voting rights; or (3) the exposure to a majority of the legal entity's economic benefits. ASU No. 2015-02 affects reporting entities that are required to evaluate whether they should consolidate certain legal entities. All legal entities are subject to reevaluation under the revised consolidation model. The guidance in ASU No. 2015-02 is effective for periods beginning after December 15, 2015. Early adoption is permitted. The Company adopted the standard effective January 1, 2015 and the adoption of this standard did not impact the Company's results of operations, cash flows or financial position.
ASU 2014-16 — In November 2014, the FASB issued ASU No. 2014-16, Derivatives and Hedging (Topic 815): Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the Form of a Share Is More Akin to Debt or to Equity , or ASU No. 2014-16. The amendments of ASU No. 2014-16 clarify how U.S. GAAP should be applied in determining whether the nature of a host contract is more akin to debt or equity and in evaluating whether the economic characteristics and risks of an embedded feature are "clearly and closely related" to its host contract. The guidance in ASU No. 2014-16 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted. The Company adopted the standard effective January 1, 2015 and the adoption of this standard did not impact the Company's results of operations, cash flows or financial position.
ASU 2014-09 — In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) , or ASU No. 2014-09.  The amendments of ASU No. 2014-09 complete the joint effort between the FASB and the International Accounting Standards Board, or IASB, to develop a common revenue standard for U.S. GAAP and International Financial Reporting Standards, or IFRS, and to improve financial reporting.  The guidance in ASU No. 2014-09 provides that an entity should recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for the goods or services provided and establishes the following steps to be applied by an entity: (1) identify the contract with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when (or as) the entity satisfies the performance obligation.  The guidance of ASU No. 2014-09 is effective for annual reporting periods beginning after December 15, 2016, including interim periods therein. Early adoption is not permitted.  The Company is currently evaluating the impact of the standard on the Company's results of operations, cash flows and financial position.

Note 3 — Business Acquisitions
2015 Acquisitions

EME-NYLD-Eligible Assets from NRG — On January 2, 2015, NRG Yield Operating LLC acquired the following projects from NRG: (i) Laredo Ridge, an 80 MW wind facility located in Petersburg, Nebraska, (ii) the Tapestry projects, which include Buffalo Bear, a 19 MW wind facility in Buffalo, Oklahoma; Taloga, a 130 MW wind facility in Putnum, Oklahoma; and Pinnacle, a 55 MW wind facility in Keyser, West Virginia, and (iii)  Walnut Creek, a 485 MW natural gas facility located in City of Industry, California, for total cash consideration of $489 million, including $9 million for working capital, plus assumed project-level debt of $737 million. NRG Yield Operating LLC funded the acquisition with cash on hand and drawings under its revolving credit facility. The assets and liabilities transferred to NRG Yield Operating LLC relate to interests under common control by NRG and accordingly, were recorded at historical cost in accordance with ASC 805-50,  Business Combinations - Related Issues . The difference between the cash paid and historical value of the entities' equity of $61 million, as well as $23 million of AOCL, were recorded as a distribution to NRG and reduced the balance of its noncontrolling interest. Since the transaction constituted a transfer of assets under common control, the guidance requires retrospective combination of the entities for all periods presented as if the combination has been in effect since the inception of common control. NRG acquired the majority of EME's assets, including Laredo Ridge, the Tapestry projects and Walnut Creek, on April 1, 2014.

Supplemental Pro Forma Information

As described above, the Company's acquisition of the EME-NYLD-Eligible Assets was accounted for as a transfer of entities under common control and all periods were retrospectively adjusted to reflect the entities as if they were transferred on the date the entities were under common control, which was April 1, 2014, the date NRG acquired Walnut Creek, Laredo Ridge and the Tapestry projects. The following unaudited supplemental pro forma information represents the results of operations as if the Company had acquired the EME-NYLD-Eligible Assets on January 1, 2014, including the impact of acquisition accounting with respect to NRG's acquisition of the projects. While the financial statements have been retrospectively adjusted, all net income or losses prior to the Company's acquisition of the projects is reflected as attributable to NRG and accordingly, no pro forma impact to earnings per Class A common share was calculated.

The following other acquisitions occurred in 2015 with a total purchase price of approximately $41 million, including $1 million paid for University of Bridgeport upon signing of the purchase agreement in the first quarter of 2015.

University of Bridgeport Fuel Cell— On April 30, 2015, the Company completed the acquisition of the University of Bridgeport Fuel Cell project in Bridgeport, CT from FuelCell Energy, Inc. The project will add an additional 1.4 MW of thermal capacity with a 12 year contract, with the option for a 7-year extension.

Spring Canyon Acquisition — On May 7, 2015, NRG Yield Operating LLC acquired a majority interest in Spring Canyon II, a 34 MW wind facility, and Spring Canyon III, a 29 MW wind facility, each located in Logan County, Colorado, from Invenergy Wind Global LLC. The purchase price was funded with cash on hand. Power generated by Spring Canyon II and Spring Canyon III is sold to Platte River Power Authority under long-term PPAs with approximately 25 years of remaining contract life.

2014 Acquisitions

Alta Wind Portfolio Acquisition — OnAugust 12, 2014, the Company acquired 100% of the membership interests of Alta Wind Asset Management Holdings, LLC, Alta Wind Company, LLC, Alta Wind X Holding Company, LLC and Alta Wind XI Holding Company, LLC, which collectively own seven wind facilities that total 947 MW located in Tehachapi, California, and a portfolio of associated land leases, or the Alta Wind Portfolio. Power generated by the Alta Wind Portfolio is sold to Southern California Edison under long-term PPAs, with 21 years of remaining contract life for Alta I-V. The Alta X and XI PPAs begin in 2016 with a term of 22 years and currently sell energy and renewable energy credits on a merchant basis.
The purchase price for the Alta Wind Portfolio was $923 million, which consisted of a base purchase price of $870 million, as well as a payment for working capital of $53 million, plus the assumption of $1.6 billion of non-recourse project-level debt. In order to fund the purchase price, the Company completed an equity offering of 12,075,000 shares of its Class A common stock at an offering price of $54.00 per share on July 29, 2014, which resulted in net proceeds of $630 million, after underwriting discounts and expenses. In addition, on August 5, 2014, NRG Yield Operating LLC issued $500 million of Senior Notes, which bear interest at a rate of 5.375% and mature in August 2024.
The acquisition was recorded as a business combination under ASC 805, with identifiable assets acquired and liabilities assumed provisionally recorded at their estimated fair values on the acquisition date. The initial accounting for the business combination is not complete because the evaluation necessary to assess the fair values of certain net assets acquired is still in process. The provisional amounts are subject to revision until the evaluations are completed to the extent that additional information is obtained about the facts and circumstances that existed as of the acquisition date. The allocation of the purchase price may be modified up to one year from the date of the acquisition as more information is obtained about the fair value of assets acquired and liabilities assumed. The following table summarizes the provisional amounts recognized for assets acquired and liabilities assumed as of December 31, 2014, as well as adjustments made through March 31, 2015.
The purchase price of $923 million was provisionally allocated as follows:

Fair value measurements
The provisional fair values of the property, plant and equipment and intangible assets at the acquisition date were measured primarily based on significant inputs that are not observable in the market and thus represent a Level 3 measurement as defined in ASC 820. Significant inputs were as follows:
 	 	
•	Property, plant and equipment— The estimated fair values were determined primarily based on an income method using discounted cash flows and validated using a cost approach based on the replacement cost of the assets less economic obsolescence. The income approach was applied by determining the enterprise value for each acquired entity and subtracting the fair value of the intangible assets and working capital to determine the implied value of the tangible fixed assets. This methodology was primarily relied upon as the forecasted cash flows incorporate the specific attributes of each asset including age, useful life, equipment condition and technology. The income approach also allows for an accurate reflection of current and expected market dynamics such as supply and demand and regulatory environment as of the acquisition date.	
 	 	
•	Intangible Assets - PPAs— The fair values of the PPAs acquired were determined utilizing a variation of the income approach where the incremental future cash flows resulting from the acquired PPAs compared to the cash flows based on current market prices were discounted to present value at a weighted average cost of capital reflective of a market participant. The values were corroborated with available market data. The PPA values will be amortized over the term of the PPAs, which approximate 22 years.	
 	 	
•	Intangible Assets - Leasehold rights— The fair values of the leasehold rights acquired, which represent the contractual right to receive royalty payments equal to a percentage of PPA revenue from certain projects, were determined utilizing the income approach. The values were corroborated with available market data. The leasehold rights values will be amortized over a period of 21 years, which is equal to the average term of the contracts.

Acquired ROFO Assets —On June 30, 2014, NRG Yield Operating LLC acquired from NRG: (i) El Segundo, a 550 MW fast-start, gas-fired facility located in Los Angeles County, California; (ii) TA High Desert, a 20 MW solar facility located in Los Angeles County, California; and (iii) Kansas South, a 20 MW solar facility located in Kings County, California. The Company paid total cash consideration of $357 million, which represents a base purchase price of $349 million and $8 million of working capital adjustments. In addition, the acquisition included the assumption of $612 million in project-level debt. The assets and liabilities transferred to the Company relate to interests under common control by NRG and accordingly, were recorded at historical cost in accordance with  ASC 805-50 . The difference between the cash proceeds and historical value of the net assets was recorded as a distribution to NRG and reduced the balance of its noncontrolling interest. Since the transaction constituted a transfer of entities under common control, the guidance requires retrospective combination of the entities for all periods presented as if the combination has been in effect since the inception of common control. Accordingly, the Company prepared its consolidated financial statements to reflect the transfer as if it had taken place from the beginning of the financial statements period, or from the date the entities were under common control, which was May 13, 2013, for Kansas South, March 28, 2013, for TA High Desert, which represent the dates these entities were acquired by NRG and January 1, 2014, which represents the beginning of the financial statements period.

Note 5 — Variable Interest Entities, or VIEs
GenConn Energy LLC — The Company has a 49.95% interest in GCE Holding LLC, the owner of GenConn, which owns and operates two 190 MW peaking generation facilities in Connecticut at the Devon and Middletown sites. Each of these facilities was constructed pursuant to a 30-year cost of service type contract with the Connecticut Light & Power Company. GenConn is considered a VIE under ASC 810, however the Company is not the primary beneficiary, and accounts for its investment under the equity method.
The project was funded through equity contributions from the owners and non-recourse, project-level debt. As of March 31, 2015, the Company's investment in GenConn was $112 million and its maximum exposure to loss is limited to its equity investment. On September 17, 2013, GenConn refinanced its existing project financing facility. The refinanced facility is comprised of a $237 million note with an interest rate of 4.73% and a maturity date of July 2041 and a 5-year, $35 million working capital facility that matures in 2018 which can be used to issue letters of credit at an interest rate of 1.875% per annum. As of March 31, 2015, $224 million was outstanding under the note and nothing was drawn on the working capital facility. The refinancing is secured by all of the GenConn assets.

NRG RPV Holdco 1 LLC — On April 9, 2015, NRG Yield RPV Holding LLC, a subsidiary of the Company, and NRG Residential Solar Solutions LLC, a subsidiary of NRG, entered into a partnership that will invest in and hold operating portfolios of residential solar assets developed by NRG Home Solar, a subsidiary of NRG, including: (i) an existing, unlevered portfolio of over 2,200 leases across nine states representing approximately 17 MW with a weighted average remaining lease term of approximately 17 years; (ii) an in-development, tax equity financed portfolio of between 6,000 to 7,000 leases across at least ten states representing approximately 48 MW with a lease term of 20 years; and (iii) an in-development tax equity financed portfolio of 5,500 to 6,500 leases representing approximately 42 MW with a lease term of 20 years. Through the partnership, the Company will invest equity in NRG RPV Holdco and receive an allocation of 95% of the partnership's taxable income and cash distributions over the contracted life of the investments. NRG will retain a 5% residual economic interest in the portfolio and will act as managing member of the partnership. The Company has committed to invest up to an additional $150 million of cash contributions with respect to the tax equity financed portfolios into the partnership over time and expects to realize an average unlevered CAFD yield of approximately 7.5% over the contracted life of these investments. Once the Company reaches its expected return on its investment, which is expected to be achieved consistent with the expiry of the remaining lease term, allocations of taxable income and cash distributions thereafter will be 95% to NRG and 5% to the Company.
The Company invested $26 million in NRG RPV Holdco in April 2015 related to the existing, unlevered portfolio of leases. The Company also invested $7 million of the $150 million investment in the tax equity financed portfolios. Its maximum exposure will be limited to its equity investment. NRG RPV Holdco is considered a VIE under ASC 810, however the Company is not the primary beneficiary, and will account for its investment under the equity method.

The fair value of notes receivable and long-term debt are based on expected future cash flows discounted at market interest rates, or current interest rates for similar instruments and are classified as Level 3 within the fair value hierarchy.
Fair Value Accounting under ASC 820
ASC 820 establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three levels as follows:
 	 	
•	Level 1—quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access as of the measurement date.	
 	 	
•	Level 2—inputs other than quoted prices included within Level 1 that are directly observable for the asset or liability or indirectly observable through corroboration with observable market data.	
 	 	
•	Level 3—unobservable inputs for the asset or liability only used when there is little, if any, market activity for the asset or liability at the measurement date.	
In accordance with ASC 820, the Company determines the level in the fair value hierarchy within which each fair value measurement in its entirety falls, based on the lowest level input that is significant to the fair value measurement.
Recurring Fair Value Measurements
The Company records its derivative assets and liabilities at fair market value on its consolidated balance sheet. The following table presents assets and liabilities measured and recorded at fair value on the Company's consolidated balance sheets on a recurring basis and their level within the fair value hierarchy:

Derivative Fair Value Measurements
A majority of the Company's contracts are non-exchange-traded and valued using prices provided by external sources. For the Company’s energy markets, management receives quotes from multiple sources. To the extent that multiple quotes are received, the prices reflect the average of the bid-ask mid-point prices obtained from all sources believed to provide the most liquid market for the commodity. The remainder of the assets and liabilities represent contracts for which external sources or observable market quotes are not available. These contracts are valued using various valuation techniques including but not limited to internal models that apply fundamental analysis of the market and corroboration with similar markets. As of March 31, 2015, there were no contracts valued with prices provided by models and other valuation techniques.
The fair value of each contract is discounted using a risk free interest rate. In addition, a credit reserve is applied to reflect credit risk, which is calculated based on credit default swaps. To the extent that the net exposure is an asset, the Company uses the counterparty’s default swap rate. If the exposure is a liability, the Company uses its default swap rate. The credit reserve is added to the discounted fair value to reflect the exit price that a market participant would be willing to receive to assume the liabilities or that a market participant would be willing to pay for the assets. As of March 31, 2015, the credit reserve resulted in a $3 million increase in fair value which is composed of a $2 million gain in OCI and a $1 million gain in interest expense. It is possible that future market prices could vary from those used in recording assets and liabilities and such variations could be material.
Concentration of Credit Risk
In addition to the credit risk discussion as disclosed in Note 2, Summary of Significant Accounting Policies,to the Company's audited consolidated financial statements included in the Company's 2014 Form 10-K , the following item is a discussion of the concentration of credit risk for the Company's financial instruments. Credit risk relates to the risk of loss resulting from non-performance or non-payment by counterparties pursuant to the terms of their contractual obligations. The Company monitors and manages credit risk through credit policies that include: (i) an established credit approval process; (ii) a daily monitoring of counterparties' credit limits; (iii) the use of credit mitigation measures such as margin, collateral, prepayment arrangements, or volumetric limits; (iv) the use of payment netting agreements; and (v) the use of master netting agreements that allow for the netting of positive and negative exposures of various contracts associated with a single counterparty. Risks surrounding counterparty performance and credit could ultimately impact the amount and timing of expected cash flows. The Company seeks to mitigate counterparty risk by having a diversified portfolio of counterparties.
Counterparty credit exposure includes credit risk exposure under certain long-term agreements, including solar and other PPAs. As external sources or observable market quotes are not available to estimate such exposure, the Company estimates the exposure related to these contracts based on various techniques including but not limited to internal models based on a fundamental analysis of the market and extrapolation of observable market data with similar characteristics. Based on these valuation techniques, as of March 31, 2015, credit risk exposure to these counterparties attributable to the Company's ownership interests was approximately $2.3 billion for the next five years. The majority of these power contracts are with utilities with strong credit quality and public utility commission or other regulatory support, as further described in Note 11,  Segment Reporting to the Company's audited consolidated financial statements included in the Company's 2014 Form 10-K.   However, such regulated utility counterparties can be impacted by changes in government regulations, which the Company is unable to predict.

Impact of Derivative Instruments on the Statements of Operations
The Company has interest rate derivative instruments that are not designated as cash flow hedges as well as ineffectiveness on cash flow hedge derivatives. The effect of interest rate hedges is recorded to interest expense. For the three months ended March 31, 2015, and 2014, the impact to the consolidated statements of operations was a loss of $12 million and $3 million, respectively.

22

                                                                        

A portion of the Company’s derivative commodity contracts relate to its Thermal Business for the purchase of fuel commodities based on the forecasted usage of the thermal district energy centers. Realized gains and losses on these contracts are reflected in the fuel costs that are permitted to be billed to customers through the related customer contracts or tariffs and accordingly, no gains or losses are reflected in the statement of operations for these contracts. Commodity contracts also hedge the forecasted sale of power for Alta X and Alta XI until the start of the PPA’s on January 1, 2016. The effect of these commodity hedges is recorded to operating revenues. For the three months ended March 31, 2015, and 2014, the impact to the consolidated statements of operations was a gain of $7 million and $0 million, respectively.
See Note 6, Fair Value of Financial Instruments, for discussion regarding concentration of credit risk.

In addition WCEP Holdings LLC partially terminated the interest rate agreements so that at least 90% and no more than 100% of the aggregate principal amount of the loans then outstanding shall be subject to interest rate agreements. As of March 31, 2015, $46 million was outstanding under the term loan.
Avenal Solar Holdings LLC
On March 18, 2015, Avenal Solar Holdings LLC, one of the Company's equity method investments, amended its credit agreement to increase its borrowings by $43 million and to reduce the related interest rate from 6 month LIBOR plus an applicable margin of 2.25% to 6 month LIBOR plus 1.75% from March 18, 2015 through March 17, 2022 and 6 month LIBOR plus 2.00% from March 18, 2022 through March 17, 2027 and 6 month LIBOR plus 2.25% from March 18, 2027 through the maturity date.  As a result of the credit agreement amendment, the Company received net proceeds of $20 million after fees from its 49.95% ownership in Avenal.

Note 9 — (Losses) Earnings Per Share 
Basic and diluted (losses) earnings per common share are computed by dividing net (loss) income by the weighted average number of common shares outstanding. Shares issued during the year are weighted for the portion of the year that they were outstanding.
The reconciliation of the Company's basic and diluted (losses) earnings per share is shown in the following table:

 	Three months ended March 31,

There were a total of seven million and four million of anti-dilutive outstanding equity instruments related to the Convertible Notes for the three months ended March 31, 2015, and March 31, 2014, respectively.
Note 10 — Changes in Capital Structure  
Recapitalization    
On February 24, 2015, the Company's board of directors approved amendments to the Company's certificate of incorporation that would adjust the Company’s capital structure by creating two new classes of capital stock, Class C common stock and Class D common stock and distribute shares of the proposed Class C and Class D common stock to holders of the Company's outstanding Class A and Class B common stock, respectively, through a stock split. The amendments were approved by the Company's stockholders at the Annual Meeting of Stockholders held on May 5, 2015, and the recapitalization is expected to become effective on or around May 14, 2015.

The Class C common stock and Class D common stock will have the same rights and privileges and rank equally, share ratably and be identical in all respects to the shares of Class A common stock and Class B common stock, respectively, as to all matters, except that each share of Class C common stock and Class D common stock will be entitled to 1/100th of a vote on all stockholder matters. The par value per share of the Company’s Class A common stock and Class B common stock will remain unchanged at $0.01 per share after the effect of the stock split described above. Accordingly, the stock split will be accounted for as a stock dividend. Once the stock dividend is authorized, on the effective date, the Company will record a transfer between retained earnings and common stock equal to the par value of each share of Class C common stock and Class D common stock that is issued. The Company will also give retroactive effect to prior period share and per share amounts in the consolidated financial statements for the effect of the stock dividend, such that all periods are comparable.
Dividends to Class A common stockholders
The following table lists the dividends paid on the Company's Class A common stock during the three months ended March 31, 2015:

 	First Quarter 2015	
Dividends per share	$	0.39	
 	
Dividends on the Class A common stock and, once outstanding, the Class C common stock, are subject to available capital, market conditions, and compliance with associated laws, regulations and other contractual obligations.
The Company also authorized 10,000,000 shares of preferred stock, par value $0.01 per share. None of the shares of preferred stock have been issued.

Note 12 — Income Taxes 
Effective Tax Rate
The income tax provision consisted of the following:

 	Three months ended March 31,	
 	2015	 	2014	
 	(In millions, except percentages)	
(Loss) Income before income taxes	$	(20	)	 	$	29	
 	
Income tax (benefit) expense	(4	)	 	3	
 	
Effective income tax rate	20.0	%	 	10.3	%	
For the three months ended March 31, 2015, the overall effective tax rate was different than the statutory rate of 35% primarily due to taxable earnings allocated to NRG resulting from its 55.3% interest in NRG Yield LLC and production tax credits generated from certain wind facilities.
For the three months ended March 31, 2014, the overall effective tax rate was different than the statutory rate of 35% primarily due to taxable earnings allocated to NRG resulting from its 65.5% interest in NRG Yield LLC.

28

                                                                        

The Company records NRG's 55.3% ownership as noncontrolling interest in the financial statements. For tax purposes, NRG Yield LLC is treated as a partnership; therefore, the Company and NRG each record their respective share of taxable income or loss.
The Company's deferred tax balances reflect the difference in book and tax basis of the Company's assets primarily due to an increase in the tax basis of property, plant and equipment. The change in tax basis resulted in a non-cash addition of $27 million during the three months ended March 31, 2015, and $65 million during the year ended December 31, 2014, to the Company's additional paid-in capital.
Note 13 — Related Party Transactions 
Management Services Agreement by and between NRG and the Company
Since the Company has no employees, NRG provides the Company with various operation, management, and administrative services, which include human resources, accounting, tax, legal, information systems, treasury, and risk management, as set forth in the Management Services Agreement. As of March 31, 2015, the base management fee was approximately $7 million per year, subject to an inflation-based adjustment annually, at an inflation factor based on the year-over-year U.S. consumer price index. The fee is also subject to adjustments following the consummation of future acquisitions and as a result of a change in the scope of services provided under the Management Services Agreement. During the three months ended March 31, 2015, the fee was increased by approximately $1 million per year in connection with the acquisition of the EME-NYLD-Eligible Assets. Costs incurred under this agreement were approximately $3 million and $2 million for the three months ended March 31, 2015 and 2014, respectively, which included certain direct expenses incurred by NRG on behalf of the Company in addition to the base management fee.
Operation and Maintenance Services (O&M) Agreements by and between NRG and Thermal Entities
On October 1, 2014, NRG entered into Plant O&M Services Agreements with certain wholly-owned subsidiaries of the Company. NRG provides necessary and appropriate services to operate and maintain the subsidiaries' plant operations, businesses and thermal facilities. NRG is to be reimbursed for the provided services, as well as for all reasonable and related expenses and expenditures, and payments to third parties for services and materials rendered to or on behalf of the parties to the agreements. NRG is not entitled to any management fee or mark-up under the agreements. Prior to October 1, 2014, NRG provided the same services to the Thermal Business on an informal basis. Total fees incurred under the agreements were $7 million for the three months ended March 31, 2015 and 2014. There was a balance of $30 million and $22 million due to NRG in accounts payable — affiliate as of March 31, 2015 and December 31, 2014, respectively.
Administrative Services Agreement by and between Marsh Landing and GenOn Energy Services, LLC
Marsh Landing is a party to an administrative services agreement with GenOn Energy Services, LLC, a wholly owned subsidiary of NRG, which provides invoice processing and payment on behalf of Marsh Landing. Marsh Landing reimburses GenOn Energy Services, LLC for the amounts paid by it. The Company reimbursed costs under this agreement of approximately $2 million for the periods ended March 31, 2015 and 2014. There was a balance of $0 million and $4 million due to GenOn Energy Services, LLC in accounts payable — affiliate as of March 31, 2015 and December 31, 2014, respectively.

Item 2 — Management's Discussion and Analysis of Financial Condition and the Results of Operations
The following discussion analyzes the Company's historical financial condition and results of operations which were recast to include the effect of the Acquired ROFO Assets and EME-NYLD-Eligible Assets on June 30, 2014, and January 2, 2015, respectively. As further discussed in Note 1,  Nature of Business  to the Consolidated Financial Statements, the purchase of these assets was accounted for in accordance with  ASC 850-50, Business Combinations - Related Issues , whereas the assets and liabilities transferred to the Company relate to interests under common control by NRG and, accordingly, were recorded at historical cost. The difference between the cash proceeds and historical value of the net assets was recorded as a distribution to NRG and reduced the balance of its noncontrolling interest. The guidance requires retrospective combination of the entities for all periods presented as if the combination has been in effect since the inception of common control.
As you read this discussion and analysis, refer to the Company's Consolidated Statements of Operations to this Form 10-Q, which present the results of operations for the three months ended March 31, 2015 and 2014. Also refer to the Company's 2014 Form 10-K, which includes detailed discussions of various items impacting the Company's business, results of operations and financial condition.
The discussion and analysis below has been organized as follows:
 	 	
•	Executive Summary, including a description of the business and significant events that are important to understanding the results of operations and financial condition;	
 	 	
•	Results of operations, including an explanation of significant differences between the periods in the specific line items of the consolidated statements of operations;	
 	 	
•	Financial condition addressing liquidity position, sources and uses of cash, capital resources and requirements, commitments, and off-balance sheet arrangements;	
 	 	
•	Known trends that may affect the Company’s results of operations and financial condition in the future; and	
 	 	
•	Critical accounting policies which are most important to both the portrayal of the Company's financial condition and results of operations, and which require management's most difficult, subjective or complex judgment.

Executive Summary
Introduction and Overview
The Company is a dividend growth-oriented company formed to serve as the primary vehicle through which NRG owns, operates and acquires contracted renewable and conventional generation and thermal infrastructure assets. The Company believes it is well positioned to be a premier company for investors seeking stable and growing dividend income from a diversified portfolio of lower-risk high-quality assets.
The Company owns a diversified portfolio of contracted renewable and conventional generation and thermal infrastructure assets in the U.S. The Company’s contracted generation portfolio collectively represents  3,630 net MW.  Each of these assets sells substantially all of its output pursuant to long-term offtake agreements with creditworthy counterparties. The average remaining contract duration of these offtake agreements was approximately  17 years as of  March 31, 2015 ,  based on cash available for distribution . The Company also owns thermal infrastructure assets with an aggregate steam and chilled water capacity of 1,310 net MWt and electric generation capacity of 123 net MW. These thermal infrastructure assets provide steam, hot water and/or chilled water, and in some instances electricity, to commercial businesses, universities, hospitals and governmental units in multiple locations, principally through long-term contracts or pursuant to rates regulated by state utility commissions.
Regulatory Matters
The Company’s regulatory matters are described in the Company’s 2014 Form 10-K in Item 1, Business —  Regulatory Matters.
As owners of power plants and participants in wholesale and thermal energy markets, certain of the Company's subsidiaries are subject to regulation by various federal and state government agencies. These include FERC and the PUCT, as well as other public utility commissions in certain states where the Company's assets are located. Each of the Company's U.S. generating facilities qualifies as an EWG or QF. In addition, the Company is subject to the market rules, procedures and protocols of the various ISO and RTO markets in which it participates. Likewise, the Company must also comply with the mandatory reliability requirements imposed by NERC and the regional reliability entities in the regions where the Company operates.
The Company's operations within the ERCOT footprint are not subject to rate regulation by FERC, as they are deemed to operate solely within the ERCOT market and not in interstate commerce. These operations are subject to regulation by PUCT.
Environmental Matters
The Company’s environmental matters are described in the Company’s 2014 Form 10-K in Item 1, Business —  Environmental Matters.
The Company is subject to a wide range of environmental laws in the development, construction, ownership and operation of projects. These laws generally require that governmental permits and approvals be obtained before construction and during operation of facilities. The Company is also subject to laws and regulations surrounding the protection of wildlife, including migratory birds, eagles and threatened and endangered species. Environmental laws have become increasingly stringent and the Company expects this trend to continue. The electric generation industry is likely to face new requirements to address various emissions, including GHG, and threatened and endangered species.
Significant Events During 2015
EME-NYLD-Eligible Assets Acquisition
On January 2, 2015, NRG Yield Operating LLC acquired the following projects from NRG: (i) Laredo Ridge, an 80 MW wind facility located in Petersburg, Nebraska; (ii) the Tapestry projects, which include Buffalo Bear, a 19 MW wind facility in Oklahoma; Taloga, a 130 MW wind facility in Oklahoma; and Pinnacle, a 55 MW wind facility in West Virginia; and (iii)  Walnut Creek, a 485 MW natural gas facility located in City of Industry, California, for total cash consideration of $489 million including adjustments of $9 million for working capital, plus assumed project level debt of $737 million. The Company funded the acquisition with cash on hand and approximately $210 million borrowed under the Company's revolving credit facility.
Recapitalization and Amended ROFO Agreement
On February 24, 2015, the Company's board of directors approved amendments to the Company's certificate of incorporation that would adjust the Company’s capital structure by creating two new classes of capital stock, Class C common stock and Class D common stock and distribute shares of the proposed Class C and Class D common stock to holders of the Company's outstanding Class A and Class B common stock, respectively, through a stock split. The amendments were approved by the Company's stockholders at the Annual Meeting of Stockholders held on May 5, 2015 and the recapitalization is expected to become effective

31

                                                                        

on or around May 14, 2015. The recapitalization enhances the Company’s ability to focus on growth opportunities without the constraints of NRG’s capital allocation to the Company, while maintaining the Company’s relationship with NRG. The recapitalization preserves NRG’s management and operational expertise, asset development and acquisition track record, financing experience and provides flexibility for the Company to raise capital to fund its growth.

The Class C common stock and Class D common stock will have the same rights and privileges and rank equally, share ratably and be identical in all respects to the shares of Class A common stock and Class B common stock, respectively, as to all matters, except that each share of Class C common stock and Class D common stock will be entitled to 1/100th of a vote on all stockholder matters.

In connection with the amendments described above, the Company and NRG agreed to amend the ROFO Agreement, effective upon the recapitalization, to make additional assets available to the Company should NRG choose to sell them, including (i) two natural gas facilities totaling 795 MW of net capacity that are expected to reach COD in 2017 and 2020, (ii) an equity interest in a wind portfolio that includes wind facilities totaling approximately 934 MW of net capacity, and (iii) up to $250 million of equity interests in one or more residential or distributed solar generation portfolios developed by affiliates of NRG.

Residential Solar Partnership with NRG
On April 9, 2015, NRG Yield RPV Holding LLC, a subsidiary of the Company, and NRG Residential Solar Solutions LLC, a subsidiary of NRG, entered into a partnership that will invest in and hold operating portfolios of residential solar assets developed by NRG Home Solar, a subsidiary of NRG, including: (i) an existing, unlevered portfolio of over 2,200 leases across nine states representing approximately 17 MW with a weighted average remaining lease term of approximately 17 years; (ii) an in-development, tax equity financed portfolio of between 6,000 to 7,000 leases across at least ten states representing approximately 48 MW with a lease term of 20 years; and (iii) an in-development tax equity financed portfolio of 5,500 to 6,500 leases representing approximately 42 MW with a lease term of 20 years. Through the partnership, the Company will invest equity in NRG RPV Holdco and receive an allocation of 95% of the partnership's taxable income and cash distributions over the contracted life of the investments. NRG will retain a 5% residual economic interest in the portfolio and will act as managing member of the partnership. The Company has committed to invest up to an additional $150 million of cash contributions with respect to the tax equity financed portfolios into the partnership over time and expects to realize an average unlevered CAFD yield of approximately 7.5% over the contracted life of these investments. Once the Company reaches its expected return on its investment, which is expected to be achieved consistent with the expiry of the remaining lease term, allocations of taxable income and cash distributions thereafter will be 95% to NRG and 5% to the Company.
Distributed Generation Partnership
The Company and NRG plan to form a new partnership that will invest in and hold operating portfolios of distributed solar assets developed by NRG. The partnership will allow NRG to periodically monetize its distributed solar investments and the Company to invest in a growing segment of the solar market.
Under the terms of the partnership agreement, the Company will receive 95% of the economics until achieving a targeted return, expected to be achieved commensurate with the end of the customer contract period, after which NRG will receive 95% of the economics. The Company has initially committed to invest up to $100 million of cash equity into the partnership over time. While none of the commitment has been utilized to date, the partnership is expected to be fully invested over the next 18 months.
El Segundo Forced Outage
In January 2015, El Segundo experienced a steam turbine water intrusion resulting in a forced outage on Units 5 and 6.  The Company has undertaken a root cause analysis and is reviewing the financial impact of repair costs and capacity revenue loss that are not otherwise covered by warranty or available insurance coverage.  The units returned to service in April 2015.
Wind Resource Availability
In the first quarter of 2015, the Company's results were impacted by lower than normal wind resource availability. While the Company's wind facilities were available, adverse weather trends had a negative impact on wind resources. The Company cannot predict the impact of this trend on future performance or results.

32

                                                                        

Basis of Presentation
The acquisitions of the TA High Desert, Kansas South, and El Segundo projects from NRG on June 30, 2014, and the Laredo Ridge, Tapestry, and Walnut Creek projects on January 2, 2015, were accounted for as a transfer of entities under common control. The guidance requires retrospective combination of the entities for all periods presented as if the combination has been in effect since the inception of common control. Accordingly, the Company prepared its consolidated financial statements to reflect the transfer as if it had taken place on January 1, 2014, or from the date the entities were under common control, which was May 13, 2013, for Kansas South, March 28, 2013, for TA High Desert, and April 1, 2014, for the EME-NYLD-Eligible Assets. Members' equity represents NRG's equity in the subsidiaries, and accordingly, in connection with their acquisition by the Company, the balance was reclassified to noncontrolling interest. The Company reduces net income attributable to its Class A common stockholders by the pre-acquisition net income for the Acquired ROFO Assets as it is not available to the stockholders.

For the same period in 2014, the Company recorded income tax expense of $3 million on pretax income of $29 million. For the three months ended March 31, 2015, the overall effective tax rate was different than the statutory rate of 35% primarily due to taxable earnings allocated to NRG resulting from its 55.3% interest in NRG Yield LLC and production tax credits generated from certain wind facilities. For the same period in 2014, the Company's overall effective tax rate was different than the statutory rate of 35% primarily due to taxable earnings allocated to NRG resulting from its 65.5% interest in NRG Yield LLC.
(Loss) Income Attributable to NRG
The Company had a loss of $11 million attributable to NRG resulting from NRG's controlling interest of 55.3% for the quarter ended March 31, 2015. The Company had income attributable to NRG of $14 million for the three months ended March 31, 2014, which resulted from the NRG's controlling interest of 65.5%.

Liquidity and Capital Resources
The Company's principal liquidity requirements are to meet its financial commitments, finance current operations, fund capital expenditures, including acquisitions from time to time, to service debt and to pay dividends. Historically, the Company's predecessor operations were financed as part of NRG's integrated operations and largely relied on internally generated cash flows as well as corporate and/or project-level borrowings to satisfy its capital expenditure requirements.  As a normal part of the Company's business, depending on market conditions, the Company will from time to time consider opportunities to repay, redeem, repurchase or refinance its indebtedness. Changes in the Company's operating plans, lower than anticipated sales, increased expenses, acquisitions or other events may cause the Company to seek additional debt or equity financing in future periods. There can be no guarantee that financing will be available on acceptable terms or at all. Debt financing, if available, could impose additional cash payment obligations and additional covenants and operating restrictions.
Liquidity Position
As of March 31, 2015, and December 31, 2014, the Company's liquidity was approximately $379 million and $863 million, respectively, comprised of cash, restricted cash, and availability under the Company's revolving credit facility. The decrease primarily relates to the acquisition of the EME-NYLD-Eligible Assets. On January 2, 2015, the Company borrowed $210 million under its revolving credit facility to fund the acquisition of Walnut Creek, Laredo Ridge and the Tapestry projects. On February 2, 2015, the Company made an optional repayment of $15 million. The Company's various financing arrangements are described in Note 8,  Long-term Debt.
Management believes that the Company's liquidity position, cash flows from operations and availability under its revolving credit facility will be adequate to meet the Company's financial commitments, debt service obligations, finance growth, operating and maintenance capital expenditures, and to fund dividends to holders of the Company's Class A common stock. Management continues to regularly monitor the Company's ability to finance the needs of its operating, financing and investing activity within the dictates of prudent balance sheet management.
Credit Ratings
Credit rating agencies rate a firm's public debt securities. These ratings are utilized by the debt markets in evaluating a firm's credit risk. Ratings influence the price paid to issue new debt securities by indicating to the market the Company's ability to pay principal, interest and preferred dividends. Rating agencies evaluate a firm's industry, cash flow, leverage, liquidity, and hedge profile, among other factors, in their credit analysis of a firm's credit risk.
The following table summarizes the credit ratings for the Company and the Senior Notes as of March 31, 2015:

 	S&P	 	Moody's	
NRG Yield, Inc. 	BB+	 	Ba1	
5.375% Senior Notes, due 2024	BB+	 	Ba1	
Sources of Liquidity
The Company's principal sources of liquidity include cash on hand, cash generated from operations, borrowings under new and existing financing arrangements and the issuance of additional equity securities as appropriate given market conditions. As described in Note 8,  Long-term Debt , the Company's financing arrangements consist of the revolving credit facility, the Convertible Notes, the Senior Notes and project-level financings for its various assets.
Recapitalization
As discussed in Significant Events During 2015 in this Item 2 above, amendments to the Company's certificate of incorporation were approved by the Company's stockholders at the Annual Meeting of Stockholders held on May 5, 2015 and the recapitalization is expected to become effective on or around May 14, 2015.

The Class C common stock and Class D common stock will have the same rights and privileges and rank equally, share ratably and be identical in all respects to the shares of Class A common stock and Class B common stock, respectively, as to all matters, except that each share of Class C common stock and Class D common stock will be entitled to 1/100th of a vote on all stockholder matters.

Uses of Liquidity
The Company's requirements for liquidity and capital resources, other than for operating its facilities, are categorized as: (i) debt service obligations, as described more fully in  Note 8 ,  Long-term Debt ; (ii) capital expenditures; (iii) acquisitions and investments; and (iv) cash dividends to investors.
Capital Expenditures
The Company's capital spending program is mainly focused on maintenance capital expenditures, or costs to maintain the assets currently operating, such as costs to replace or refurbish assets during routine maintenance. The Company develops annual capital spending plans based on projected requirements for maintenance capital. For the three months ended  March 31, 2015  and 2014, the Company used approximately $3 million and $22 million, respectively, to fund capital expenditures. The capital expenditures in the first quarter of 2015 primarily related to maintenance expense. During the first quarter of 2015, the Company did not incur significant growth capital expenditures related to the  construction of new assets and/or the completion of the construction of new assets if already in process.
In January 2015, El Segundo experienced a steam turbine water intrusion resulting in a forced outage on Units 5 and 6.  The Company has undertaken a root cause analysis and is reviewing the financial impact of repair costs and capacity revenue loss that are not otherwise covered by warranty or available insurance coverage.  The units returned to service in April 2015.

Acquisitions and Investments
The Company intends to acquire generation assets developed and constructed by NRG in the future, as well as generation and thermal infrastructure assets from third parties where the Company believes its knowledge of the market, operating expertise and access to capital provides a competitive advantage, and to utilize such acquisitions as a means to grow its cash available for distribution. 
On January 2, 2015, NRG Yield Operating LLC acquired the following projects from NRG: (i) Laredo Ridge, a 80 MW wind facility located in Petersburg, Nebraska; (ii) the Tapestry projects, which include Buffalo Bear, a 19 MW wind facility in Oklahoma, Taloga, a 130 MW wind facility in Oklahoma, and Pinnacle, a 55 MW wind facility in West Virginia; and (iii)  Walnut Creek, a 485 MW natural gas facility located in City of Industry, California, for total cash consideration of $489 million including adjustments of $9 million for working capital, plus assumed project level debt of $737 million. The Company funded the acquisition with cash on hand and approximately $210 million borrowed under the Company's revolving credit facility.
On May 7, 2015, NRG Yield Operating LLC acquired a majority interest in Spring Canyon II, a 34 MW wind facility, and Spring Canyon III, a 29 MW wind facility, each located in Logan County, Colorado, from Invenergy Wind Global LLC. The purchase price was funded with cash on hand. Power generated by Spring Canyon II and Spring Canyon III is sold to Platte River Power Authority under long-term PPAs with approximately 25 years of remaining contract life.

On April 9, 2015, NRG Yield RPV Holding LLC, a subsidiary of the Company, and NRG Residential Solar Solutions LLC, a subsidiary of NRG, entered into a partnership that will invest in and hold operating portfolios of residential solar assets developed by NRG Home Solar, a subsidiary of NRG, including: (i) an existing, unlevered portfolio of over 2,200 leases across nine states representing approximately 17 MW with a weighted average remaining lease term of approximately 17 years; (ii) an in-development, tax equity financed portfolio of between 6,000 to 7,000 leases across at least ten states representing approximately 48 MW with a lease term of 20 years; and (iii) an in-development tax equity financed portfolio of 5,500 to 6,500 leases representing approximately 42 MW with a lease term of 20 years. Through the partnership, the Company will invest equity in NRG RPV Holdco and receive an allocation of 95% of the partnership's taxable income and cash distributions over the contracted life of the investments. NRG will retain a 5% residual economic interest in the portfolio and will act as managing member of the partnership. The Company has committed to invest up to an additional $150 million of cash contributions with respect to the tax equity financed portfolios into the partnership over time and expects to realize an average unlevered CAFD yield of approximately 7.5% over the contracted life of these investments. Once the Company reaches its expected return on its investment, which is expected to be achieved consistent with the expiry of the remaining lease term, allocations of taxable income and cash distributions thereafter will be 95% to NRG and 5% to the Company.
The Company invested $26 million in NRG RPV Holdco in April 2015 related to the existing, unlevered portfolio of leases. The Company also invested $7 million of the $150 million investment in the tax equity financed portfolios. Its maximum exposure will be limited to its equity investment.

Cash Dividends to Investors
The Company intends to use the amount of cash that it receives from its distributions from NRG Yield LLC to pay quarterly dividends to the holders of its Class A common stock, and, once outstanding, its Class C common stock. NRG Yield LLC intends to distribute to its unit holders in the form of a quarterly distribution all of the cash available for distribution that is generated each quarter less reserves for the prudent conduct of the business, including among others, maintenance capital expenditures to maintain the operating capacity of the assets. Cash available for distribution is defined as earnings before income taxes, depreciation and amortization, excluding contract amortization, cash interest paid, income taxes paid, maintenance capital expenditures, investments in unconsolidated affiliates, growth capital expenditures, net of capital and debt funding, and principal amortization of indebtedness, and including cash distributions from unconsolidated affiliates.  The common stock dividend is subject to available capital, market conditions, and compliance with associated laws, regulations and other contractual obligations. The Company expects that, based on current circumstances, comparable cash dividends will continue to be paid in the foreseeable future.
The following table lists the dividends paid on the Company's Class A common stock during the three months ended March 31, 2015:

 	 	First Quarter 2015	
Dividends per share	 	$	0.39	
 	
As a result of the recapitalization, the Company will adjust its dividend policy to reflect the additional number of shares of Class C common stock that will be outstanding. The Company expects to pay a quarterly dividend of $0.20 per share (representing $0.80 per share annualized on a post-split basis, or $1.60 per share annualized on a pre-split basis) beginning on June 15, 2015 to stockholders of record of Class A and Class C common stock as of June 1, 2015.

NOLs, Deferred Tax Assets and Uncertain Tax Position Implications, under ASC 740
As of March 31, 2015, the Company has a cumulative federal NOL carry forward balance of $219 million for financial statement purposes, which will begin expiring in 2033. As a result of the Company's tax position, and based on current forecasts, the Company does not anticipate significant income tax payments for federal, state and local jurisdictions in 2015.
The Company has no uncertain tax benefits.
Off-Balance Sheet Arrangements
Obligations under Certain Guarantee Contracts
The Company may enter into guarantee arrangements in the normal course of business to facilitate commercial transactions with third parties.
Retained or Contingent Interests
The Company does not have any material retained or contingent interests in assets transferred to an unconsolidated entity.
Obligations Arising Out of a Variable Interest in an Unconsolidated Entity
Variable interest in equity investments — As of March 31, 2015, the Company has several investments with an ownership interest percentage of 50% or less in energy and energy-related entities that are accounted for under the equity method. One of these investments, GenConn Energy LLC, is a variable interest entity for which the Company is not the primary beneficiary.
The Company's pro-rata share of non-recourse debt held by unconsolidated affiliates was approximately $580 million as of March 31, 2015. This indebtedness may restrict the ability of these subsidiaries to issue dividends or distributions to the Company. See also Note 5,  Variable Interest Entities, or VIEs .
Contractual Obligations and Commercial Commitments
The Company has a variety of contractual obligations and other commercial commitments that represent prospective cash requirements in addition to our capital expenditure programs, as disclosed in the Company's 2014 Form 10-K. See also Note 8, Long-term Debt  for additional discussion of contractual obligations incurred during the three months ended March 31, 2015.
Fair Value of Derivative Instruments
The Company may enter into fuel purchase contracts and other energy-related financial instruments to mitigate variability in earnings due to fluctuations in spot market prices and to hedge fuel requirements at certain generation facilities. In addition, in order to mitigate interest rate risk associated with the issuance of variable rate and fixed rate debt, the Company enters into interest rate swap agreements.

The Company has elected to disclose derivative assets and liabilities on a trade-by-trade basis and does not offset amounts at the counterparty master agreement level. As discussed below in  Quantitative and Qualitative Disclosures about Market Risk -Commodity Price Risk,  NRG, on behalf of the  Company, measures the sensitivity of the portfolio to potential changes in market prices using VaR, a statistical model which attempts to predict risk of loss based on market price and volatility. NRG's risk management policy places a limit on one-day holding period VaR, which limits the net open position.
Critical Accounting Policies and Estimates
The Company's discussion and analysis of the financial condition and results of operations are based upon the consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these financial statements and related disclosures in compliance with U.S. GAAP requires the application of appropriate technical accounting rules and guidance as well as the use of estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosures of contingent assets and liabilities. The application of these policies necessarily involves judgments regarding future events, including the likelihood of success of particular projects, legal and regulatory challenges, and the fair value of certain assets and liabilities. These judgments, in and of themselves, could materially affect the financial statements and disclosures based on varying assumptions, which may be appropriate to use. In addition, the financial and operating environment may also have a significant effect, not only on the operation of the business, but on the results reported through the application of accounting measures used in preparing the financial statements and related disclosures, even if the nature of the accounting policies has not changed.
On an ongoing basis, the Company evaluates these estimates, utilizing historic experience, consultation with experts and other methods the Company considers reasonable. In any event, actual results may differ substantially from the Company's estimates. Any effects on the Company's business, financial position or results of operations resulting from revisions to these estimates are recorded in the period in which the information that gives rise to the revision becomes known.
The Company's significant accounting policies are summarized in Note 2, Summary of Significant Accounting Policies. The Company identifies its most critical accounting policies as those that are the most pervasive and important to the portrayal of the Company's financial position and results of operations, and that require the most difficult, subjective and/or complex judgments by management regarding estimates about matters that are inherently uncertain. The Company's critical accounting policies include income taxes and valuation allowance for deferred tax assets, impairment of long lived assets and other intangible assets, and acquisition accounting.
Recent Accounting Developments

Item 3 — Quantitative and Qualitative Disclosures About Market Risk
The Company is exposed to several market risks in its normal business activities. Market risk is the potential loss that may result from market changes associated with the Company's power generation or with an existing or forecasted financial or commodity transaction. The types of market risks the Company is exposed to are commodity price risk, interest rate risk, liquidity risk, and credit risk.
Commodity Price Risk
Commodity price risks result from exposures to changes in spot prices, forward prices, volatilities, and correlations between various commodities, such as electricity, natural gas and emissions credits. The Company manages the commodity price risk of its merchant generation operations by entering into derivative or non-derivative instruments to hedge the variability in future cash flows from forecasted power sales or purchases of fuel. The portion of forecasted transactions hedged may vary based upon management's assessment of market, weather, operation and other factors.
Based on a sensitivity analysis using simplified assumptions, the impact of a $0.50 per MMBtu increase or decrease in natural gas prices across the term of the derivative contracts would cause a change of approximately $2 million in the net value of derivatives as of  March 31, 2015 .
Interest Rate Risk
The Company is exposed to fluctuations in interest rates through its issuance of variable rate debt. Exposures to interest rate fluctuations may be mitigated by entering into derivative instruments known as interest rate swaps, caps, collars and put or call options. These contracts reduce exposure to interest rate volatility and result in primarily fixed rate debt obligations when taking into account the combination of the variable rate debt and the interest rate derivative instrument. NRG's risk management policies allow the Company to reduce interest rate exposure from variable rate debt obligations.
Most of the Company's project subsidiaries enter into interest rate swaps, intended to hedge the risks associated with interest rates on non-recourse project level debt. See Note 9,  Long-Term Debt,  to the Company's audited consolidated financial statements included in the Company's 2014 Form 10-K, and  Note 8,  Long-term Debt , to this Form 10-Q for more information about interest rate swaps of the Company's project subsidiaries.
If all of the above swaps had been discontinued on March 31, 2015, the Company would have owed the counterparties $143 million. Based on the investment grade rating of the counterparties, the Company believes its exposure to credit risk due to nonperformance by counterparties to its hedge contracts to be insignificant.
The Company has long-term debt instruments that subject it to the risk of loss associated with movements in market interest rates. As of  March 31, 2015 , a 1% change in interest rates would result in an approximately $3 million change in interest expense on a rolling twelve month basis.
As of March 31, 2015, the fair value of the Company's debt was $5,037 million and the carrying value was $4,937 million. The Company estimates that a 1% decrease in market interest rates would have increased the fair value of its long-term debt by $297 million.
Liquidity Risk
Liquidity risk arises from the general funding needs of the Company's activities and in the management of the Company's assets and liabilities.
Counterparty Credit Risk
Credit risk relates to the risk of loss resulting from non-performance or non-payment by counterparties pursuant to the terms of their contractual obligations. The Company monitors and manages credit risk through credit policies that include: (i) an established credit approval process; and (ii) the use of credit mitigation measures such as prepayment arrangements or volumetric limits. Risks surrounding counterparty performance and credit could ultimately impact the amount and timing of expected cash flows. The Company seeks to mitigate counterparty risk by having a diversified portfolio of counterparties.
