Report of Independent Registered Public Accounting Firm To the Stockholders and the Board of Directors of TerraForm Power, Inc. Opinion on Internal Control over Financial Reporting We have audited TerraForm Power, Inc. and subsidiaries internal control over financial reporting as of December 31, 2019, based on
criteria established in Internal ControlIntegrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, because of the effect of the material weakness
described below on the achievement of the objectives of the control criteria, TerraForm Power, Inc. and subsidiaries (the Company) has not maintained effective internal control over financial reporting as of December 31, 2019, based on the COSO
criteria. As indicated in the accompanying Managements Report on Internal Control over Financial Reporting, managements
assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of the 320 MW distributed generation portfolio acquired on September 26, 2019, which is included in the 2019
consolidated financial statements of the Company and constituted approximately 8% of consolidated total assets as of December 31, 2019 and approximately 1% of consolidated total operating revenues for the year then ended. Our audit of internal
control over financial reporting of the Company also did not include an evaluation of the internal control over financial reporting of the 320 MW distributed generation portfolio acquired on September 26, 2019. A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a
reasonable possibility that a material misstatement of the companys annual or interim financial statements will not be prevented or detected on a timely basis. The following material weaknesses have been identified and included in
managements assessment:  

The Companys risk assessment process failed to identify certain risks of material misstatement of the
financial statements and as a result the Company did not have effective review controls to address those risks of material misstatement of significant accounts, including risks related to the completeness and accuracy of information derived from IT
systems and end-user computing spreadsheets used in the performance of those controls.  

The Company did not have sufficient resources to have effective controls over the application of GAAP and
accounting measurements related to certain significant accounts, transactions and related financial statement disclosures. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the 2019
consolidated financial statements of the Company. These material weaknesses were considered in determining the nature, timing and extent of audit tests applied in our audit of the 2019 consolidated financial statements, and this report does not
affect our report dated March 17, 2020, which expressed an unqualified opinion thereon. Basis for Opinion The Companys management is responsible for maintaining effective internal control over financial reporting and for its assessment of the
effectiveness of internal control over financial reporting included in the accompanying Managements Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Companys internal control
over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and
regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit in accordance with the standards of the
PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness
exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a
reasonable basis for our opinion.  F-83

Definition and Limitations of Internal Control Over Financial Reporting A companys internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of
financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A companys internal control over financial reporting includes those policies and procedures that
(1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as
necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors
of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the companys assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of
any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.  /s/ Ernst & Young LLPNew York, New YorkMarch 17, 2020  F-84

Report of Independent Registered Public Accounting Firm To the Stockholders and the Board of Directors of TerraForm Power, Inc. Opinion on the Financial Statements We
have audited the accompanying consolidated balance sheets of TerraForm Power, Inc. and subsidiaries (the Company) as of December 31, 2019 and 2018, the related consolidated statements of operations, comprehensive loss, stockholders
equity, and cash flows for each of the two years in the period ended December 31, 2019, and the related notes (collectively referred to as the consolidated financial statements). In our opinion, based on our audits and the report of
other auditors, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2019 and 2018, and the results of its operations and its cash flows for each of the two years
in the period ended December 31, 2019, in conformity with U.S. generally accepted accounting principles. We did not audit the 2018
financial statements of TERP Spanish Holdco, S.L., a wholly-owned subsidiary, which reflect total assets constituting 36% at December 31, 2018, and total revenues constituting 29% in 2018, of the related consolidated totals. Those statements
were audited by other auditors whose report has been furnished to us, and our opinion, insofar as it relates to the amounts included for TERP Spanish Holdco, S.L., is based solely on the report of the other auditors. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the
Companys internal control over financial reporting as of December 31, 2019, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013
framework), and our report dated March 17, 2020 expressedan adverse opinion thereon. Adoption of New Accounting Standards As discussed in Note 2 to the consolidated financial statements, the Company changed its method for recognizing revenue as a result of the
adoption of Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (Topic 606), and the amendments in ASUs 2015-14, 2016-08, 2016-10 and 2016-12 effective January 1, 2018. As discussed in Note 2 to the consolidated financial statements, the Company changed its accounting for leases in 2019 due to the adoption of
the Accounting Standards Update (ASU) No. 2016-02,Leases (Topic 842), and the amendments in ASU No. 2018-11 effective January 1, 2019. Basis for Opinion These financial
statements are the responsibility of the Companys management. Our responsibility is to express an opinion on the Companys financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are
required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether
due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the
accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits and the report of other auditors during 2018 provide a reasonable basis
for our opinion. Critical Audit Matters The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were
communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments.
The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the
critical audit matters or on the accounts or disclosures to which they relate.  F-85

Accounting for AcquisitionsDescription of the Matter

As described in Note 3 to the consolidated financial statements, TerraForm Power acquired several domestic distributed generation portfolios
of renewable energy facilities from WGL Energy Systems, Inc. and WGSW, Inc. for a purchase price of $735 million and acquired several solar photovoltaic renewable energy facilities from subsidiaries of
X-Elio Energy, S.L., a Spanish corporation, for a total purchase price of approximately $71 million (collectively, the 2019 Acquisitions). The Company also completed the acquisition accounting
and recorded measurement period adjustments in connection with the 2018 acquisition of Saeta Yield, S.A. (the 2018 Acquisition) during the year ended December 31, 2019.
 Auditing the Companys accounting for the 2019 Acquisitions was complex due to the
significant estimation required by management to determine the fair values of renewable energy facilities and identified intangible assets. Auditing the Companys accounting for the measurement period adjustments for the 2018 Acquisition was
complex due to the significant estimation required by management to determine the fair value of debt in international jurisdictions. The assumptions used to estimate the fair value of the renewable energy facilities and intangible assets included
the replacement cost per megawatt, discount rate, and certain assumptions that form the basis of the prospective financial information (PFI) (e.g., current and future power pricing agreement rates and operational data). Further,
determining the interest rates used in calculating the fair value of debt in international jurisdictions required a significant level of subjectivity as the resultant values were highly sensitive to the selected rates. These assumptions are forward
looking and could be affected by future economic and market conditions.How We Addressed the Matter in Our
Audit

To test the fair value of the renewable energy facilities and intangible assets, our audit procedures included, among others, assessing the
significant assumptions described above and testing the completeness and accuracy of the underlying data. For example, we evaluated the estimated cash flows based on future generation volume by comparing the estimated future generation volume to
historical generation volume and comparing the forward power pricing to long term power purchase agreements or Spanish government regulated rates, as applicable. We involved our valuation specialists to assist in evaluating the significant
assumptions, including replacement cost assumptions used to estimate the fair value of renewable energy facilities, discount rates, and valuation methodologies used in the Companys models.
 To test the measurement period adjustments related to the fair value of debt in
international jurisdictions, we performed audit procedures that included evaluating the Companys valuation methodology and significant assumptions. For example, with the assistance of our valuation specialists, we compared the estimated credit
spreads used in the valuation of the assumed debt instruments to market information, including corporate debt indices, and evaluated the effects of prepayment provisions within the debt arrangements on the calculated fair values.Level 3 Derivative Financial Instruments Fair Value MeasurementDescription of the Matter

As described in Note 13 to the consolidated financial statements, as of December 31, 2019, the aggregate fair value of Level 3
derivative instruments was $59.3 million. The Companys long-term physically-settled commodity contracts are considered Level 3 fair value measurements as they contain significant unobservable inputs. The Company uses a discounted
cash flow valuation technique and an option model, when applicable to determine the fair value of its derivative assets. 
Auditing the fair value measurement of Level 3 derivative financial instruments was complex given the complexity of the model used to value the option
component of the derivative instruments and the judgmental nature of the assumptions used as inputs into the valuation model. In particular, the Company used significant unobservable inputs such as the forward commodity prices based on forward
commodity curves and implied volatilities for the option component.  F-86




---

How We Addressed theMatter in Our Audit

To test the valuation of Level 3 derivative financial instruments, our audit procedures included, among others, evaluating the valuation methodologies used by the Company and testing significant inputs, estimates and the
mathematical accuracy of the calculations. In certain instances, with the assistance of our valuation specialists, we independently determined the significant assumptions (including long-dated forward pricing and implied volatilities), calculated
the resultant fair values and compared them to the Companys estimates. We obtained forward prices from independent sources, including broker quotes and counterparty fair values, and evaluated the Companys assumptions related to their
forward curves and confirmed key inputs with counterparties. We also performed sensitivity analyses using independent sources of market data to evaluate the change in fair value of Level 3 derivative financial instruments that would result from
changes in underlying assumptions.Impairment of Long-lived AssetsDescription of the Matter

As described in Note 2 to the consolidated financial statements, the Company reviews long-lived assets that are held and used for impairment
whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable (impairment indicators). When impairment indicators are identified, the Company is required to perform a recoverability test using an
estimate of future undiscounted cash flows for the long-lived asset group to compare to the respective carrying amount to determine whether the asset group is recoverable. 
Auditing the Companys identification of impairment indicators involved significant auditor judgment due to the many geographic, regulatory and economic
environments in which the Company operates, which requires an evaluation of a wide variety of factors in the evaluation of potential impairment indicators. Additionally, when impairment indicators were present, auditing the Companys
recoverability test involved a high degree of subjectivity as the estimates underlying the determination of undiscounted cash flows of the asset group were based on entity-specific assumptions about future performance and industry conditions.
Significant assumptions used in the Companys undiscounted cash flow estimates included energy generation forecasts and unobservable forward energy market prices. Further, the identified material weakness relating to the Company not having
effective review controls over the completeness and accuracy of information derived from IT systems and end-user computing spreadsheets used in the performance of those controls affected our audit procedures
in this area.How We Addressed theMatter in Our Audit

To test the Companys identification of impairment indicators, our audit procedures included, among others, making inquiries of
management to understand changes in the businesses, reading industry journals or publications to independently identify adverse changes in the regulatory environments or the geographic areas and evaluating the completeness of managements
assessment and analysis of the identified changes and whether they represented impairment indicators. 
To test the Companys recoverability tests, our audit procedures included, among others, evaluating the significant assumptions and operating data used to
estimate future undiscounted cash flows. For example, we compared the significant assumptions to power curves, current industry trends, historical generation volumes, and power purchase agreements. We also performed sensitivity analyses of the
significant assumptions to evaluate the change in the undiscounted cash flow estimate that would result from changes in the assumptions. We also recalculated managements estimated undiscounted cash flows and compared them to the carrying value
of the respective long-lived asset groups.  To respond to the material weakness, we
performed incremental audit procedures to assess the completeness and accuracy of data used in the recoverability tests. For example, we agreed energy prices used in the recoverability tests to power purchase agreements and evaluated the future
undiscounted cash flows of the long-lived asset group by comparing them to historical revenue and expense trends.  F-87

Measurement of non-controlling interestsDescription of the Matter

As described in Note 2 to the consolidated financial statements, non-controlling interests represent
the portion of net assets in consolidated entities that are not owned by the Company and are reported in the consolidated balance sheets. As of December 31, 2019, non-controlling interests totaled
$605 million, redeemable non-controlling interests totaled $23 million, and net loss attributable to non-controlling interests and redeemable non-controlling interests (collectively, non-controlling interests) for the year ended December 31, 2019 was $46 million and $12 million,
respectively.  Auditing non-controlling
interests was complex due to the number of unique substantive profit-sharing arrangements and the complexity involved in developing and maintaining the Hypothetical Liquidation at Book Value (HLBV) model for each partnership or similar
agreement that is used to allocate the current period net income or loss between the Company and the non-controlling interest holders. Further, the earnings allocated to the
non-controlling interest holders was sensitive to certain income tax-related inputs to the tax capital accounts that are used in the HLBV models. Further, the identified
material weakness relating to the Company not having sufficient resources to have effective internal controls over the application of U.S. GAAP and accounting measurements related to significant accounts, transactions and related financial statement
disclosures affected our audit procedures in this area.How We Addressed theMatter in Our Audit

To test the measurement of non-controlling interests, our audit procedures included, among others, testing the measurement of the tax capital accounts used in the HLBV models, including
verifying capital contributions and distributions to supporting documentation, evaluating the calculation and allocation of taxable income, and examining the HLBV models for compliance with the contractual provisions in the partnership or similar
agreement. We tested the completeness and accuracy of the underlying data used in the HLBV models, including U.S. GAAP and income tax-related inputs. To respond to the material weakness, we involved tax
subject matter professionals to assist in evaluating the calculation of the tax capital accounts in accordance with the Internal Revenue Code, as well as compliance with the contractual provisions in the partnership or similar agreement.Realizability of Deferred Tax AssetsDescription of the Matter

As described in Note 11 to the consolidated financial statements, at December 31, 2019 the Company recorded gross deferred tax assets of
$768 million, which were reduced by a valuation allowance of $414 million. Deferred tax assets are reduced by a valuation allowance if, based on the weight of all available evidence, it is more likely than not that some portion, or all, of
the deferred tax assets will not be realized.  Auditing managements assessment
of realizability of deferred tax assets involved complex auditor judgment because determining whether the future taxable income expected to be generated from the reversal of existing taxable temporary differences is more likely than not to result in
the realization of existing deferred tax assets required management to make interpretations of the tax law and assumptions about reversal patterns that may be affected by future events.How We Addressed theMatter in Our Audit

To test the realizability of deferred tax assets, our audit procedures included, among others, testing the Companys analysis of the reversal of existing taxable temporary differences. For example, we tested the completeness
and accuracy of the underlying data and the appropriateness of significant inputs and assumptions including the estimated reversal patterns for the existing taxable temporary differences. We tested the completeness and measurement of the
Companys tax attributes related to net operating losses and interest deduction limitation carryforwards generated in the US and foreign jurisdictions. With the assistance of our tax professionals, we evaluated the net operating loss
carryforward periods as well as the amount of future taxable income that can be reduced by net operating loss carryforwards after an ownership change under Section 382 of the Internal Revenue Code.  /s/ Ernst & Young LLPWe have served as the Companys auditor since 2018.New York, New YorkMarch 17, 2020  F-88

TERRAFORM POWER, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Dollar amounts in thousands, except per share data, unless otherwise noted) 1. NATURE OF OPERATIONS AND ORGANIZATION Nature of Operations TerraForm
Power, Inc. (TerraForm Power and, together with its subsidiaries, the Company) is a holding company and its primary asset is an equity interest in TerraForm Power, LLC (Terra LLC). TerraForm Power is the managing
member of Terra LLC and operates, controls and consolidates the business affairs of Terra LLC, which through its subsidiaries owns and operates renewable energy facilities that have long-term contractual arrangements to sell the electricity
generated by these facilities to third parties. The related green energy certificates, ancillary services and other environmental attributes generated by these facilities are also sold to third parties. The Company is sponsored by Brookfield Asset
Management Inc. (Brookfield) and its primary business strategy is to acquire operating solar and wind assets in North America and Western Europe. The Company is a controlled affiliate of Brookfield. As of December 31, 2019,
affiliates of Brookfield held approximately 62% of the Companys Common Stock. Brookfield Renewable Non-Binding Proposal and Signing of
Reorganization Agreement On January 11, 2020, the Company received an unsolicited and
non-binding proposal (the Brookfield Proposal) from Brookfield Renewable Partners L.P. (Brookfield Renewable), an affiliate of Brookfield, to acquire all of the outstanding shares of
Common Stock of the Company, other than the approximately 62% shares held by Brookfield and its affiliates. The Brookfield Proposal expressly conditioned the transaction contemplated thereby on the approval of a committee of the Board of Directors
of the Company (the Board) consisting solely of independent directors and the approval of a majority of the shares held by the Companys stockholders not affiliated with Brookfield Renewable and its affiliates. Following the
Companys receipt of the Brookfield Proposal, the Board formed a special committee (the Special Committee) of non-executive, disinterested and independent directors to, among other things,
review, evaluate and consider the Brookfield Proposal and, if the Special Committee deemed appropriate, negotiate a transaction with Brookfield Renewable or explore alternatives thereto. The Board resolutions establishing the Special Committee
expressly provided that the Board would not approve the transaction contemplated by the Brookfield Proposal or any alternative thereto without a prior favorable recommendation by the Special Committee. Brookfield Renewable holds an approximately 30%
indirect economic interest in TerraForm Power. On March 16, 2020, pursuant to the Brookfield Proposal, the Company and Brookfield
Renewable and certain of their affiliates entered into a definitive agreement (the Reorganization Agreement) for Brookfield Renewable to acquire all of the Companys outstanding shares of Common Stock, other than the approximately
62% currently owned by Brookfield Renewable and its affiliates (the transactions contemplated by the Reorganization Agreement, the Transactions). Pursuant to the Reorganization Agreement, each holder of a share of Common Stock that is
issued and outstanding immediately prior to the consummation of the Transactions will receive, at each such shareholders election, 0.381 of a Brookfield Renewable limited partnership unit or of a Class A exchangeable subordinate voting
share of Brookfield Renewable Corporation, a Canadian subsidiary of Brookfield Renewable which is expected to be publicly listed as of the consummation of the Transactions. The Special Committee has unanimously recommended that the Companys
unaffiliated shareholders approve the Transactions. Consummation of the Transactions is subject to the non-waivable approval of a majority of the Companys shareholders not affiliated with Brookfield Renewable, receipt of required regulatory
approvals and other customary closing conditions. The Consummation of the Brookfield Sponsorship Transaction and the Settlement with SunEdison Prior to the consummation of the Merger (as defined below) on October 16, 2017, TerraForm Power was a controlled affiliate of
SunEdison (together with its consolidated subsidiaries and excluding the Company and TerraForm Global, Inc. (TerraForm Global) and their subsidiaries, SunEdison). Upon the consummation of the Merger, a change of control of
TerraForm Power occurred, and Orion US Holdings 1 L.P. (Orion Holdings), an affiliate of Brookfield, held 51% of the voting securities of TerraForm Power. As a result of the Merger, TerraForm Power is no longer a controlled affiliate of
SunEdison and became a controlled affiliate of Brookfield. In June 2018, TerraForm Power closed a private placement to certain affiliates of Brookfield such that, as of December 31, 2018, affiliates of Brookfield held approximately 65% of
TerraForm Powers Common Stock. On October 8, 2019, the Company completed a public offering and a simultaneous private placement to certain affiliates of Brookfield of its Common Stock whereby as of December 31, 2019, the combined
ownership of affiliates of Brookfield was approximately 62%. On April 21, 2016, SunEdison and certain of its domestic and
international subsidiaries (the SunEdison Debtors) voluntarily filed for protection under Chapter 11 of the U.S. Bankruptcy Code (the SunEdison Bankruptcy). In response to SunEdisons financial and operating
difficulties, the Company initiated a process for the exploration and evaluation of potential strategic alternatives for the Company, including potential transactions to secure a new sponsor or sell the Company, and a process to settle claims with
SunEdison. This process resulted in the Companys entry into a definitive Merger and Sponsorship Transaction agreement on March 6, 2017 with Orion Holdings and BRE TERP Holdings Inc. (Merger Sub), a wholly-owned subsidiary of
Orion Holdings, each of which is an affiliate of Brookfield. At the same time, the Company and SunEdison also entered into a settlement agreement (the Settlement Agreement) and a voting and support agreement (the Voting and Support
Agreement), to among other things, facilitate the closing of the Merger and the settlement of claims between the Company and SunEdison. On October 6, 2017, the Merger Agreement was approved by the holders of a majority of the outstanding Class A shares of TerraForm
Power, excluding SunEdison, Orion Holdings, any of their respective affiliates or any person with whom any of them has formed (and not terminated) a group (as such term is defined in the Securities Exchange Act of 1934 as amended, the
Exchange Act) and by the holders of a majority of the total voting power of the outstanding shares of the  F-98




---

Companys common stock entitled to vote on the transaction. With these votes, all conditions to the merger transaction contemplated by the Merger Agreement were satisfied. On
October 16, 2017, Merger Sub merged with and into TerraForm Power (the Merger), with TerraForm Power continuing as the surviving corporation in the Merger. Immediately following the consummation of the Merger, there were 148,086,027
Class A shares of TerraForm Power outstanding (which excludes 138,402 Class A shares that were issued and held in treasury to pay applicable employee tax withholdings for restricted stock units (RSUs) held by employees that
vested upon the consummation of the Merger) and Orion Holdings held 51% of such shares. In addition, pursuant to the Merger Agreement, at or prior to the effective time of the Merger, the Company and Orion Holdings (or one of its affiliates), among
other parties, entered into a suite of agreements providing for sponsorship arrangements, including a master services agreement, relationship agreement, governance agreement and a sponsor line of credit (the Sponsorship Transaction), as
are more fully described in Note 10. Long-term Debt and Note 21. Related Parties. Immediately prior to the effective
time of the Merger, pursuant to the Settlement Agreement, SunEdison exchanged all of the Class B units held by SunEdison or any of its controlled affiliates in Terra LLC for 48,202,310 Class A shares of TerraForm Power, and as a result of
this exchange, all shares of Class B common stock of TerraForm Power held by SunEdison or any of its controlled affiliates were automatically redeemed and retired. Pursuant to the Settlement Agreement, immediately following this exchange, the
Company issued to SunEdison additional Class A shares such that immediately prior to the effective time of the Merger, SunEdison and certain of its affiliates held an aggregate number of Class A shares equal to 36.9% of the Companys
fully diluted share count (which was subject to proration based on the Merger consideration election results as discussed in Note 16.Stockholders Equity). SunEdison and certain of its affiliates also transferred
all of the outstanding IDRs of Terra LLC held by SunEdison or certain of its affiliates to Brookfield IDR Holder at the effective time of the Merger. Under the Settlement Agreement, upon the consummation of the Merger, all agreements between the
Company and the SunEdison Debtors were deemed rejected, subject to certain limited exceptions, without further liability, claims or damages on the part of the Company. The settlements, mutual release and certain other terms and conditions of the
Settlement Agreement also became effective upon the consummation of the Merger, as more fully discussed in Note 21. Related Parties. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements represent the results of TerraForm Power, which consolidates Terra LLC through its
controlling interest. The accompanying consolidated financial statements have been prepared in accordance with accounting principles
generally accepted in the United States of America (U.S. GAAP). They include the results of wholly-owned and partially-owned subsidiaries in which the Company has a controlling interest with all significant intercompany accounts and
transactions eliminated. The Company elected not to push-down the application of the acquisition method of accounting to its consolidated
financial statements following the consummation of the Merger and the change of control that occurred, as discussed in Note 1. Nature of Operations and Organization. Reclassifications Certain prior
period amounts that existed within the consolidated balance sheets as of December 31, 2018, have been reclassified to conform to the current period presentation. Specifically, the Company presented the balances of current and non-current
derivative assets and liabilities, and prepaid expenses separately on the consolidated balance sheets. Additionally, the Company presented the balances of current and non-current deferred revenue as components of current and non-current other
liabilities, as appropriate. Use of Estimates In preparing the consolidated financial statements, the Company uses estimates and assumptions that affect the reported amounts of assets and
liabilities and the disclosure of contingent assets and liabilities as of the date of the financial statements. Such estimates also affect the reported amounts of revenues, expenses, and cash flows during the reporting period. To the extent there
are material differences between the estimates and actual results, the Companys future results of operations would be affected. Cash and Cash
Equivalents Cash and cash equivalents include all cash balances and money market funds with original maturity periods of three
months or less when purchased.  F-99

Restricted Cash Restricted cash consists of cash on deposit in financial institutions that is restricted to satisfy the requirements of certain debt agreements
and funds held within the Companys project companies that are restricted for current debt service payments and other purposes in accordance with the applicable debt agreements. These restrictions include: (i) cash on deposit in collateral
accounts, debt service reserve accounts and maintenance reserve accounts; and (ii) cash on deposit in operating accounts but subject to distribution restrictions related to debt defaults existing as of the date of the balance sheet. Restricted
cash that is not expected to become unrestricted within twelve months from the date of the balance sheet is presented within non-current assets in the consolidated balance sheets. Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are reported on the consolidated balance sheets, including both billed and unbilled amounts, and are adjusted for the
allowance for doubtful accounts and any write-offs. The Company establishes an allowance for doubtful accounts to adjust its receivables to amounts considered to be ultimately collectible, and charges to the allowance are recorded within general and
administrative expenses or cost of operations, as appropriate, in the consolidated statements of operations. The Companys allowance for doubtful accounts is based on a variety of factors, including the length of time receivables are past due,
significant one-time events, the financial health of its customers, and historical experience. The allowance for doubtful accounts was $1.4 million and $1.6 million as of December 31, 2019, and
2018, respectively, and charges (reductions) to the allowance recorded within general and administrative expenses for the years ended December 31, 2019, 2018 and 2017 were $0.2 million, $0.1 million and $(1.5) million, respectively.
Accounts receivable are written off in the period in which the receivable is deemed uncollectible, and collection efforts have been exhausted. There were no write-offs of accounts receivable for the years ended December 31, 2019, 2018, and
2017. Renewable Energy Facilities Renewable energy facilities consist of solar generation and storage facilities and wind power plants that are stated at cost. Expenditures for
major additions and improvements are capitalized, and minor replacements, maintenance, and repairs are charged to expense as incurred. Depreciation of the Companys solar and storage facilities is recognized using the straight-line composite
method over their estimated useful lives which ranged from 12 to 28 years and 23 to 30 years, as of December 31, 2019 and 2018, respectively. Under this method, the Companys assets with similar characteristics and estimated useful lives are
grouped and depreciated as a single unit. Depreciation of the Companys wind power plant is calculated based on the major components of wind power plants and is recognized over the estimated periods during which these major components remain in
service. The Companys major components of wind power plants had remaining useful lives ranging from 8 to 36 years. As of December 31, 2019 and 2018, they had a weighted average remaining useful life of 19
and 21 years, respectively. Construction in-progress represents the cumulative
construction costs, including the costs incurred for the purchase of major equipment and engineering costs and any capitalized interest. Once the project achieves commercial operation, the Company reclassifies the amounts recorded in construction in
progress to renewable energy facilities in service. Finite-Lived Intangibles The Companys finite-lived intangible assets and liabilities represent revenue contracts, consisting of long-term licensing agreements,
power purchase contracts (PPAs), and renewable energy credits (RECs) that were obtained through third-party acquisitions. The revenue contract intangibles comprise favorable and unfavorable rate PPAs and REC agreements and
the in-place value of market-rate PPAs. Intangible assets and liabilities that have determinable estimated lives are amortized on a straight-line basis over those estimated lives. Amortization of favorable and
unfavorable rate revenue contracts is recorded within operating revenues, net in the consolidated statements of operations. Amortization expense related to the licensing contracts and in-place value of
market-rate revenue contracts is recorded within depreciation, accretion and amortization expense in the consolidated statements of operations. The straight-line method of amortization is used because it best reflects the pattern in which the
economic benefits of the intangibles are consumed or otherwise used up. The amounts and useful lives assigned to intangible assets acquired and liabilities assumed impact the amount and timing of future amortization. Impairment of Renewable Energy Facilities and Intangibles Long-lived assets that are held and used are reviewed for impairment whenever events or changes in circumstances indicate that the carrying
amounts may not be recoverable. An impairment loss is recognized when indicators of impairment are present and the total future estimated undiscounted cash flows expected from an asset are less than its carrying value. The Company review our current
activities, changes in the conditions of our renewable energy facilities and the market conditions  F-100




---

in which they operate to determine the existence of any indicators requiring an impairment analysis. Indicators of potential impairment for a long-lived asset group, generally this is an
individual renewable energy project, include a substantial and sustained decline in the trading price of our Common Stock, severe adverse changes in the financial condition of a customer to our offtake agreements, a significant decline in forecasted
operating revenues and earnings of our operating projects, and deterioration in the performance of our renewable energy facilities. An impairment charge is measured as the difference between a long lived asset groups carrying amount and its
fair value. The fair values are determined by a variety of valuation methods, including appraisals, sales prices of similar assets, and present value techniques. During the year ended December 31, 2018, the Company recognized a $15.2 million non-cash
impairment charge within its Solar reporting segment related to an operating project within a distributed generation portfolio due to the bankruptcy of a significant customer. During the year ended December 31, 2017, the Company recognized an
impairment charge of $1.4 million, within impairment of renewable energy facilities in the consolidated statements of operations, on its 11.4 MW portfolio of residential rooftop solar assets that was classified as held for sale as of
December 31, 2016, and subsequently sold in 2017. See Note 3. Acquisitions and Divestitures and Note 6. Renewable Energy Facilities for further discussion. Goodwill The Company evaluates
goodwill for impairment at least annually on December 1. The Company performs an impairment test between scheduled annual tests if facts and circumstances indicate that it is more-likely-than-not that the fair
value of a reporting unit that has goodwill is less than its carrying value. A reporting unit is either the operating segment level or one level below, which is referred to as a component. The level at which the impairment test is performed requires
judgment as to whether the operations below the operating segment constitute a self-sustaining business or whether the operations are similar such that they should be aggregated for purposes of the impairment test. The Company defines its reporting
units to be consistent with its operating segments. The Company may first make a qualitative assessment of whether it is more-likely-than-not that a reporting units fair value is less than its carrying value to determine whether it is necessary to perform the quantitative goodwill impairment test. The qualitative impairment test
includes considering various factors, including macroeconomic conditions, industry and market conditions, cost factors, a sustained share price or market capitalization decrease, and any reporting unit specific events. If it is determined through
the qualitative assessment that a reporting units fair value is more-likely-than-not greater than its carrying value, the quantitative impairment test is not required. If the qualitative assessment
indicates it is more-likely-than-not that a reporting units fair value is not greater than its carrying value, the Company must perform the quantitative impairment test. The Company may also elect to
proceed directly to the quantitative impairment test without considering such qualitative factors. The quantitative impairment test is
the comparison of the fair value of a reporting unit with its carrying amount, including goodwill. In accordance with the authoritative guidance over fair value measurements, the Company defines the fair value of a reporting unit as the price that
would be received to sell the unit as a whole in an orderly transaction between market participants at the measurement date. The Company primarily uses the income approach methodology of valuation, which uses the discounted cash flow method to
estimate the fair values of the Companys reporting units. The Company does not believe that a cost approach is relevant to measuring the fair values of its reporting units. Significant management judgment is required when estimating the fair value of the Companys reporting units, including the forecasting of
future operating results, the discount rates and expected future growth rates that it uses in the discounted cash flow method of valuation, and in the selection of comparable businesses that are used in the market approach. If the estimated fair
value of the reporting unit exceeds the carrying value assigned to that unit, goodwill is not impaired. If the carrying value assigned to a reporting unit exceeds its estimated fair value, the Company records an impairment charge based on the excess
of the reporting units carrying amount over its fair value. The impairment charge is limited to the amount of goodwill allocated to the reporting unit. The Company performed a qualitative impairment test for the goodwill balance of $128.0 million, and concluded that the carrying amount of
the related reporting units does not exceed its fair value. No goodwill impairment charges were recorded for the years ended December 31, 2019, 2018 and 2017. Financing Lease Obligations Certain of the Companys assets were financed with sale-leaseback arrangements. Proceeds received from a sale-leaseback are treated using
the financing method when the sale of the renewable energy facility is not recognizable. A sale is not recognized when the leaseback arrangements include a prohibited form of continuing involvement, such as an option or  F-101




---

obligation to repurchase the assets under the Companys master lease agreements. Under these arrangements, the Company does not recognize any profit until the sale is recognizable, which the
Company expects to recognize at the end of the arrangement when the contract is canceled and the initial deposits received are forfeited by the financing party. The Company is required to make rental payments throughout the leaseback arrangements. These payments are allocated between principal and
interest payments using an effective yield method. Deferred Financing Costs Financing costs incurred in connection with obtaining senior notes and term financing are deferred and amortized over the maturities of the
respective financing arrangements using the effective interest method and are presented as a direct deduction from the carrying amount of the related debt (see Note 10. Long-term Debtfor additional details), except for the costs
related to the Companys revolving credit facilities, which are presented as a non-current asset on the consolidated balance sheets within other assets. As of December 31, 2019, 2018 and 2017, the
Company had $10.8 million, $6.7 million, and $9.4 million, respectively, of unamortized deferred financing costs related to its revolving credit facilities. Inventory Inventory consists of
spare parts and is recorded at the lower of the weighted average cost of purchase or net realizable value within other current assets in the consolidated balance sheets. Spare parts are expensed to cost of operations in the consolidated statements
of operations or capitalized to renewable energy facilities when installed or used, as appropriate. Asset Retirement Obligations Asset retirement obligations are accounted for in accordance with Accounting Standards Codification (ASC) 410-20, Asset Retirement Obligations. Retirement obligations associated with renewable energy facilities included within the scope of ASC 410-20 are those for which a
legal obligation exists under enacted laws, statutes, and written or oral contracts, and for which the timing and/or method of settlement may be conditional on a future event. Asset retirement obligations are recognized at fair value in the period
in which they are incurred, and a corresponding asset retirement costs are recognized within the related renewable energy facilities. Over time, the asset retirement cost is depreciated over the estimated useful life of the related renewable energy
facility, and the asset retirement obligation is accreted to its expected future value. The Company generally reviews its asset
retirement obligations annually, based on its review of updated cost studies, as necessary, and its evaluation of cost escalation factors. The Company evaluates newly assumed costs or substantive changes in previously assumed costs to determine if
the cost estimate impacts are sufficiently material to warrant the application of the updated estimates to the asset retirement obligations. Changes resulting from revisions to the timing or amount of the original estimate of cash flows are
recognized as an increase or a decrease in the asset retirement cost to the extent applicable. Revenue from Contracts with Customers Adoption of Topic 606 On January 1,
2018, the Company adopted ASU No. 2014-09, Revenue from Contracts with Customers and ASU No. 2016-08, Revenue from Contracts with Customers (Topic
606), Principal versus Agent Considerations (Reporting Revenue Gross versus Net)(collectively referred to as Topic 606) for all revenue contracts in scope, which primarily included bundled energy and incentive sales through PPAs,
individual REC sales, and upfront sales of federal and state incentive benefits recorded. The Company elected to use the contract modification practical expedient for purposes of computing the cumulative-effect adjustment recorded to the balances of
stockholders equity as of January 1, 2018. The Company evaluated the impact of Topic 606 as it relates to the individual sale
of RECs. In certain jurisdictions, there may be a lag between physical generation of the underlying energy and the transfer of RECs to the customer due to administrative processes imposed by state regulations. Under the Companys previous
accounting policy, revenue was recognized as the underlying electricity was generated if the sale had been contracted with the customer. Based on the framework in Topic 606, for a portion of the existing individual REC sale arrangements where the
transfer of control to the customer is determined to occur upon the transfer of the RECs, the Company currently recognizes revenue commensurate with the transfer of RECs to the customer as compared to the generation of the underlying energy under
the previous accounting policy. Revenue recognition practices for the remainder of existing individual REC sale arrangements remain the same; that is, revenue is recognized based on the underlying generation of energy because the contracted RECs are
produced from a designated facility and control of the RECs transfers to the customer upon generation of the underlying energy. The adoption of  F-102




---

Topic 606, as it relates to the individual sale of RECs, resulted in an increase in accumulated deficit on January 1, 2018, of $20.5 million, net of tax, and net of $0.3 million
and $4.5 million that were allocated to non-controlling interests and redeemable non-controlling interests, respectively. The adjustments for accumulated deficit
and non-controlling interests are reflected within cumulative-effect adjustment in the consolidated statements of stockholders equity for the year ended December 31, 2018, and the redeemable non-controlling interests adjustment is reflected within cumulative-effect adjustment in the redeemable non-controlling interests roll-forward presented in Note 18. Non-controlling Interests. The Company evaluated the impact of Topic 606 as it relates to the
upfront sale of investment tax credits (ITCs) through its lease pass-through fund arrangements. The amounts allocated to the ITCs were initially recorded as deferred revenue in the consolidated balance sheets, and subsequently, one-fifth of the amounts allocated to the ITCs was recognized annually as incentives revenue in the consolidated statements of operations based on the anniversary of each solar energy systems placed-in-service date. The Company concluded that revenue related to the sale of ITCs through its lease pass-through arrangements should be recognized at the point in time
when the related solar energy systems are placed in service. Previously, the Company recognized this revenue evenly over the five-year ITC recapture period. The Company concluded that the likelihood of a recapture event related to these assessments
is remote. The adoption of Topic 606, as it relates to the upfront sale of ITCs, resulted in a decrease in accumulated deficit on January 1, 2018 of $40.9 million, net of tax, which is reflected within cumulative-effect adjustment in the
consolidated statements of stockholders equity for the year ended December 31, 2018. The impact on the Companys results of operations for the year ended December 31, 2018 resulted in a decrease in
non-cash deferred revenue recognition of $16.3 million. PPA Rental Income The majority of the Companys energy revenue is derived from long-term PPAs accounted for as operating leases under ASC 840,
Leases. Rental income under these lease agreements is recorded as revenue when the electricity is delivered to the customer. The Company adopted ASC 842,Leases on January 1, 2019, and elected certain of the practical expedients
permitted in the issued standard, including the expedient that permits the Company to retain its existing lease assessment and classification. Solar
and Wind PPA Revenue PPAs that are not accounted for under the scope of leases or derivatives are accounted for under Topic 606. The
Company typically delivers bundled goods consisting of energy and incentive products for a singular rate based on a unit of generation at a specified facility over the term of the agreement. In these types of arrangements, the volume reflects total
energy generation measured in Kilowatt hours (kWhs), which can vary period to period depending on system and resource availability. The contract rate per unit of generation (kWhs) is generally fixed at contract inception; however,
certain pricing arrangements can provide for time-of-delivery, seasonal, or market index adjustment mechanisms over time. The customer is invoiced monthly equal to the
volume of energy delivered multiplied by the applicable contract rate. The Company considers bundled energy and incentive products within
PPAs to be distinct performance obligations. A contracts transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied under Topic 606. The Company views
the sale of energy as a series of distinct goods that is substantially the same and has the same pattern of transfer measured by the output method. Although the Company views incentive products in bundled PPAs to be performance obligations satisfied
at a point in time, measurement of satisfaction and transfer of control to the customer in a bundled arrangement coincides with a pattern of revenue recognition with the underlying energy generation. Accordingly, the Company applied the practical
expedient in Topic 606 as the right to consideration corresponds directly to the value provided to the customer to recognize revenue at the invoice amount for its standalone and bundled PPA contracts. Commodity Derivatives The Company has
certain revenue contracts within its wind fleet that are accounted for as derivatives under the scope of ASC 815, Derivatives and Hedging. Amounts recognized within operating revenues, net in the consolidated statements of operations consist
of cash settlements and unrealized gains and losses representing changes in fair value for the commodity derivatives that are not designated as hedging instruments. See Note 12. Derivatives for further discussion.  F-103

Regulated Solar and Wind Energy Revenue Regulated solar and wind includes revenue generated by Saetas solar and wind operations in Spain, which are subject to regulations
applicable to companies that generate production from renewable sources for facilities located in Spain. While Saetas Spanish operations are regulated by the Spanish regulator, the Company has determined that the Spanish entities do not meet
the criteria of a rate-regulated entity under ASC 980 Regulated Operations, since the rates established by the Spanish regulator are not designed to recover the entitys costs of providing its energy generation services. Accordingly, the
Company applied Topic 606 to recognize revenue for these customer contract arrangements. The Company has distinct performance obligations to deliver electricity, capacity, and incentives which are discussed below. The Company has a performance obligation to deliver electricity and these sales are invoiced monthly at the wholesale market price (subject to
adjustments due to regulatory price bands that reduce market risk). The Company transfers control of the electricity over time and the customer receives and consumes the benefit simultaneously. Accordingly, the Company applied the practical
expedient in Topic 606 as the right to consideration corresponds directly to the value provided to the customer to recognize revenue at the invoice amount for electricity sales. The Company has a stand-ready performance obligation to deliver capacity in the Spanish electricity market in which these renewable energy
facilities are located. Proceeds received by the Company from the customer in exchange for capacity are determined by a remuneration on an investment per unit of installed capacity that is determined by the Spanish regulators. The Company satisfies
its performance obligation for capacity under a time-based measure of progress and recognizes revenue by allocating the total annual consideration evenly to each month of service. Regulated Solar and Wind Incentive Revenue For the Companys Spanish solar renewable energy facilities, the Company has identified a performance obligation linked to an incentive
that is distinct from the electricity and capacity deliveries discussed above. For solar technologies under the Spanish market, the customer makes an operating payment per MWh which is calculated based on the difference of a standard cost and an
expected market price, both, determined by the Spanish regulator. The customer is invoiced monthly equal to the volume of energy produced multiplied by the regulated rate. The performance obligation is satisfied when the Company generates
electricity from the solar renewable facility. The Company recognizes revenue based on the amount invoiced each month. Amortization of Favorable and
Unfavorable Rate-Revenue Contracts The Company accounts for its business combinations by recognizing in the financial statements the
identifiable assets acquired, the liabilities assumed and any non-controlling interests in the acquiree at fair value at the acquisition date. Intangible amortization of certain revenue contracts acquired
in business combinations (favorable and unfavorable rate PPAs and REC agreements) is recognized on a straight-line basis over the remaining contract term. The current period amortization for favorable rate revenue contracts is reflected as a
reduction to operating revenues, net, and amortization for unfavorable rate revenue contracts is reflected as an increase to operating revenues, net. SeeNote7. Intangible Assets, Net and Goodwillfor additional
details. Solar and Wind Incentive Revenue The Company generates incentive revenue from individual incentive agreements relating to the sale of RECs and performance-based incentives to
third-party customers that are not bundled with the underlying energy output. The majority of individual REC sales reflect a fixed quantity, fixed price structure over a specified term. The Company views REC products in these arrangements as
distinct performance obligations satisfied at a point in time. Since the REC products delivered to the customer are not linked to the underlying generation of a specified facility, these RECs are recognized into revenue when delivered. The Company
typically receives payment within 30 days of invoiced REC revenue. For certain incentive contract arrangements, the quantity
delivered to the customer is linked to a specific facility. The pattern of revenue recognition for these incentive arrangements is recognized over time coinciding with the underlying revenue generation from the related facility. See Note 4. Revenue for additional disclosures. Leases In February 2016, the
Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-02, Leases (Topic 842), which primarily changes the lessees accounting for
operating leases by requiring the recognition of lease right-of-use assets and lease liabilities. The guidance also eliminates previous real estate specific provisions.
In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842), Targeted Improvements, which amended the  F-104




---

standard to give entities another option to apply the requirements of the standard in the period of adoption (January 1, 2019) or Effective Date Method. The Company adopted the new accounting
guidance on January 1, 2019 using a modified retrospective approach reflecting the Effective Date Method of adoption in which the Company continued to apply the guidance in ASC 840, Leases to the comparable periods presented in the year of
adoption. The Company made the following elections provided under the standard:  

The package of practical expedients that permits the Company to retain its existing lease assessment and
classification;  

The practical expedient that allows the Company to not evaluate existing and expired land easements;  

The practical expedient to not separate non-lease components in power
purchase agreements (PPAs) in which the Company is the lessor in providing energy, capacity, and incentive products for a bundled fixed rate; and  

The Company elected not to apply the recognition requirements for short-term operating leases, defined as a term
of twelve months or shorter, from the commencement date. The Company evaluated the impact of Topic 842 as it relates to
operating leases for land, buildings and equipment for which it is the lessee and reviewed its existing contracts for embedded leases. The adoption of the new standard resulted in the recognition of right-of-use assets and lease liabilities of approximately $262.1 million and $256.0 million, respectively, as of January 1, 2019, for operating leases, whereas the Companys accounting
for finance leases remained substantially unchanged. The Company has operating leases for renewable energy production facilities, land,
office space, transmission lines, vehicles and other operating equipment. Leases with an initial term of twelve months or shorter are not recorded on the balance sheet, but are expensed on a straight-line basis over the lease term. During the year
ended December 31, 2019, the Company did not have any leases with an initial term of less than twelve months. Operating lease right-of-use assets are included within renewable energy facilities, net, whereas right-of-use
liabilities are included within accounts payable, accrued expenses and other current liabilities. Right-of-use assets represent the right to use an underlying asset for
the lease term and lease liabilities represent the obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are
recognized at the lease commencement date based on the present value of lease payments over the lease term. As the Companys leases do not provide an implicit rate, the Company calculated an incremental borrowing rate by leveraging external
transactions at comparable entities and internally available information to determine the present value of lease payments. The Companys leases have remaining lease terms ranging from 5 to 41 years. The Companys lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will
exercise any such options. Lease expense is recognized on a straight-line basis over the expected lease term. Although some of the Companys leases contain lease and non-lease components, the Company
applies the practical expedient to account for each lease component and non-lease component as a single lease component. Lease payments include fixed rent and taxes, where applicable, and exclude variable
rental payments that include other operating expenses is recognized as incurred. The Companys lease agreements do not contain any material residual value guarantees or material restrictive covenants. The following tables outline the different
components of operating leases and other terms and conditions of the lease agreements where the Company is the lessee. As discussed
above, a significant portion of the Companys operating revenues are generated from delivering electricity and related products from owned solar and wind renewable energy facilities under PPAs in which the Company is the lessor. Revenue is
recognized when electricity is delivered and is accounted for as rental income under the lease standard. The adoption of ASC 842 did not have an impact on the accounting policy for rental income from the Companys PPAs in which it is the
lessor. The Company elected the package of practical expedients available under ASC 842, which did not require the Company to reassess its lease classification from ASC 840. Additionally, the Company elected the practical expedient to not separate
lease and non-lease components for lessors. This election allows energy (lease component) and environmental incentives or renewable energy certificates (non-lease
components) under bundled PPAs to be accounted as a singular lease unit of account under ASC 842. See Note 8. Leases for
additional disclosures. Income Taxes The Company accounts for income taxes using the liability method, which requires it to use the asset and liability method of accounting for
deferred income taxes and provide deferred income taxes for all significant temporary differences.  F-105




---

The Company reports certain of its revenues and expenses differently for financial statement
purposes than for income tax return purposes, resulting in temporary and permanent differences between the Companys financial statements and income tax returns. The tax effects of such temporary differences are recorded as either deferred
income tax assets or deferred income tax liabilities in the Companys consolidated balance sheets. The Company measures its deferred income tax assets and deferred income tax liabilities using enacted tax rates that are expected to be in effect
when the deferred tax liabilities are expected to be realized or settled. Many factors are considered when assessing the likelihood of future realization of deferred tax assets, including recent earnings within taxing jurisdictions, expectations of
future taxable income, the carry forward periods available and other relevant factors. The Company believes it is more likely than not that the future reversal of existing taxable temporary differences will allow the Company to realize deferred tax
assets, net of valuation allowances. A valuation allowance is recorded to reduce the net deferred tax assets to an amount that is more-likely-than-not to be realized. Tax benefits are recognized when it is more-likely-than-not that a tax position will be sustained upon examination by the authorities. The benefit recognized from a position that has surpassed the
more-likely-than-not threshold is the largest amount of benefit that is more than 50% likely to be realized upon settlement. The Company recognizes interest and penalties related to uncertain tax
benefits as a component of income tax expense. Changes to existing net deferred tax assets or valuation allowances or changes to uncertain tax benefits are recorded to income tax expense in the period such determination is made. The Company releases the taxes deferred in AOCI as the individual units of account (i.e., derivative instruments in a cash flow hedge or net
investment hedge relationships) are terminated, extinguished, sold or substantially liquidated. Adoption of ASU
2018-02 During the fourth quarter of 2018, the Company early adopted ASU No. 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income addressing certain stranded income tax effects in AOCI resulting from the U.S. governments enactment
of the Tax Cuts and Jobs Act (the Tax Act) on December 22, 2017. The adoption of ASU No. 2018-12 resulted in reclassifying $9.4 million of stranded tax effects on the net unrealized
gains on derivatives designated as hedging instruments in a cash flow relationship from AOCI to accumulated deficit. The reclassification is reflected as an increase to accumulated deficit within the cumulative-effect adjustment in the consolidated
statements of stockholders equity for the year ended December 31, 2018, and an increase to the opening balance of AOCI as of January 1, 2018. Variable Interest Entities The
Company assesses entities for consolidation in accordance with ASC 810. The Company consolidates variable interest entities (VIEs)in renewable energy facilities when determined to be the primary beneficiary. VIEs are entities
that lack one or more of the characteristics of a voting interest entity (VOE). The Company has a controlling financial interest in a VIE when its variable interest or interests provide it with (i) the power to direct the activities
of the VIE that most significantly impact the VIEs economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. VOEs are entities in which (i) the total equity investment at risk is sufficient to enable the entity to finance its activities
independently and (ii) the equity holders have the power to direct the activities of the entity that most significantly impact its economic performance, the obligation to absorb the losses of the entity and the right to receive the residual
returns of the entity. The usual condition for a controlling financial interest in a voting interest entity is ownership of a majority voting interest. If the Company has a majority voting interest in a voting interest entity, the entity is
consolidated. For the Companys consolidated VIEs, the Company has presented on its consolidated balance sheets, to the extent
material, the assets of its consolidated VIEs that can only be used to settle specific obligations of the consolidated VIE, and the liabilities of its consolidated VIEs for which creditors do not have recourse to the Companys general assets
outside of the VIE. Non-controlling Interests and Hypothetical Liquidation at Book Value (HLBV) Non-controlling interests represent the portion of net assets in consolidated entities
that are not owned by the Company and are reported as a component of equity in the consolidated balance sheets. Non-controlling interests in subsidiaries that are redeemable either at the option of the holder
or at fixed and determinable prices at certain dates in the future are classified as redeemable non-controlling interests in subsidiaries between liabilities and stockholders equity in the consolidated
balance sheets. Redeemable non-controlling interests that are currently redeemable or redeemable after the passage of time are adjusted to their redemption value as changes occur. The Company applies the
guidance in ASC 810-10 along with the Securities and Exchange Commission (SEC) guidance in ASC
480-10-S99-3A in the valuation of redeemable non-controlling interests.  F-106




---

The Company has determined the allocation of economics between the controlling party and the
third party for non-controlling interests does not correspond to ownership percentages for certain of its consolidated subsidiaries. In order to reflect the substantive profit sharing arrangements, the
Company has determined that the appropriate methodology for determining the value of non-controlling interests is a balance sheet approach using the HLBV method. Under the HLBV method, the amounts reported as non-controlling interest on the consolidated balance sheets represent the amounts the third party investors could hypothetically receive at each balance sheet reporting date based on the liquidation provisions of
the respective operating partnership agreements. HLBV assumes that the proceeds available for distribution are equivalent to the unadjusted, stand-alone net assets of each respective partnership, as determined under U.S. GAAP. The third
party non-controlling interests in the consolidated statements of operations and statements of comprehensive loss are determined based on the difference in the carrying amounts of non-controlling interests on the consolidated balance sheets between reporting dates, adjusted for any capital transactions between the Company and third party investors that occurred during the respective
period. Where, prior to the commencement of operating activities for a respective renewable energy facility, HLBV results in an immediate
change in the carrying value of non-controlling interests on the consolidated balance sheets due to the recognition of ITCs or other adjustments as required by the U.S. Internal Revenue Code, the Company
defers the recognition of the respective adjustments and recognizes the adjustments in non-controlling interest on the consolidated statements of operations on a straight-line basis over the expected life of
the underlying assets giving rise to the respective difference. Similarly, where the Company has acquired a controlling interest in a partnership and there is a resulting difference between the initial fair value of non-controlling interest and the value of non-controlling interest as measured using HLBV, the Company initially records
non-controlling interests at fair value and amortizes the resulting difference over the remaining life of the underlying assets. Contingencies The Company is
involved in conditions, situations or circumstances in the ordinary course of business with possible gain or loss contingencies that will ultimately be resolved when one or more future events occur or fail to occur. If some amount within a range of
loss appears at the time to be a better estimate than any other amount within the range, that amount will be accrued. When no amount within the range is a better estimate than any other amount, the minimum amount in the range will be accrued. The
Company continually evaluates uncertainties associated with loss contingencies and records a charge equal to at least the minimum estimated liability for a loss contingency when both of the following conditions are met: (i) information
available prior to the issuance of the financial statements indicates that it is probable that an asset had been impaired or a liability had been incurred at the date of the financial statements; and (ii) the loss or range of loss can be
reasonably estimated. Legal costs are expensed when incurred. Gain contingencies are not recorded until realized or realizable. Derivative
Financial Instruments Adoption of ASU 2017-12 On January 1, 2018, the Company adopted ASU No. 2017-12, Derivatives and Hedging (Topic
815): Targeted Improvements to Accounting for Hedging Activities which primarily resulted in simplification of the assessment of hedge effectiveness for derivatives designated in a qualifying cash flow relationship, and the periodic recognition
of gains and losses related to certain components of AOCI. The Company adopted ASU No. 2017-12 using the modified retrospective transition method resulting in a cumulative-effect adjustment of
$4.2 million, net of tax of $1.6 million, representing a decrease in accumulated deficit and AOCI, which is reflected within cumulative-effect adjustment in the consolidated statements of stockholders equity for the year ended
December 31, 2018. Initial Recognition The Company recognizes its derivative instruments as assets or liabilities at fair value in the consolidated balance sheets on a trade date
basis unless they qualify for certain exceptions, including the normal purchases and normal sales exception. Accounting for changes in the fair value (i.e., gains or losses) of a derivative instrument depends on whether it has been designated as
part of a hedging relationship and the type of hedging relationship. Derivatives that qualify and are designated for hedge accounting are
classified as either hedges of the variability of expected future cash flows to be received or paid related to a recognized asset or liability (cash flow hedges) or hedges of the exposure to foreign currency of a net investment in a foreign
operation (net investment hedges). The Company also uses derivative contracts outside the hedging program to manage foreign currency risk
associated with intercompany loans.  F-107




---

Subsequent Measurement The change in fair value of components included in the effectiveness assessment of derivative instruments designated as cash flow hedges is
recognized as a component of OCI and reclassified into earnings on a trade date basis in the period that the hedged transaction affects earnings. The change in fair value of components included in the effectiveness assessment of foreign currency
contracts designated as net investment hedges is recorded in cumulative translation adjustments within AOCI and reclassified into earnings when the foreign operation is sold or substantially liquidated. The change in fair value of derivative contracts intended to serve as economic hedges that are not designated as hedging instruments is
reported as a component of earnings in the consolidated statements of operations. Cash flows from derivative instruments designated as
net investment hedges and non-designated derivatives used to manage foreign currency risks associated with intercompany loans are classified as investing activities in the consolidated statements of cash
flows. Cash flows from all other derivative instruments are classified as operating activities in the consolidated statements of cash flows. Fair
Value Measurements The Company performs fair value measurements defined as the price that would be received from selling an asset
or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required to be recorded at their fair values, the Company
considers the principal or most advantageous market in which it would transact and considers assumptions that market participants would use when pricing the assets or liabilities, such as inherent risk, transfer restrictions and risk of
nonperformance. In determining fair value measurements, the Company maximizes the use of observable inputs and minimizes the use of
unobservable inputs. Assets and liabilities are categorized within a fair value hierarchy based upon the lowest level of input that is significant to the fair value measurement:  

Level 1: Quoted prices in active markets for identical assets or liabilities;  

Level 2: Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted
prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active or other inputs that are observable or can be corroborated by observable market data for
substantially the full term of the assets or liabilities; or  

Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to
the fair values of the assets or liabilities. The Company maintains various financial instruments recorded at cost in
the consolidated balance sheets that are not required to be recorded at fair value. For cash and cash equivalents, restricted cash, accounts receivable, prepaid expenses and other current assets, accounts payable and accrued expenses and other
current liabilities and due to affiliates, net, the carrying amount approximates fair value because of the short-term maturity of the instruments. See Note 13. Fair Value of Financial Instruments for disclosures related to the fair value of
the Companys derivative instruments and long-term debt. Foreign Currency The Companys reporting currency is the U.S. dollar. Certain of the Companys subsidiaries maintain their records in local currencies
other than the U.S. dollar, which are their functional currencies. When a subsidiarys local currency is considered its functional currency, the Company translates its assets and liabilities to U.S. dollars using exchange rates in effect at
date of the financial statements and its revenue and expense accounts to U.S. dollars at average exchange rates for the period. Cumulative translation adjustments are reported in AOCI in stockholders equity. Cumulative translation adjustments
are reclassified from AOCI to earnings only when realized upon sale or upon complete or substantially complete liquidation of an investment in a foreign subsidiary. Transaction gains and losses and changes in fair value of the Companys foreign
exchange derivative contracts not accounted for under hedge accounting are included in results of operations as recognized.  F-108




---

Business Combinations and Acquisitions of Assets The Company applies the definition of a business in ASC 805, Business Combinations to determine whether it is acquiring a business or a
group of assets. The Company accounts for its business combinations by recognizing in the financial statements the identifiable assets
acquired, the liabilities assumed and any non-controlling interests in the acquiree at fair value at the acquisition date. The Company also recognizes and measures the goodwill acquired or a gain from a
bargain purchase in the business combination and determines what information to disclose to enable users of an entitys financial statements to evaluate the nature and financial effects of the business combination. In addition, acquisition
costs related to business combinations are expensed as incurred. When the Company acquires a renewable energy business, the purchase
price is allocated to (i) the acquired tangible assets and liabilities assumed, primarily consisting of land, plant and long-term debt, (ii) the identified intangible assets and liabilities, primarily consisting of the value of favorable
and unfavorable rate PPAs, REC agreements, the licensing contracts and in-place value of market rate PPAs, (iii) non-controlling interests, and (iv) other
working capital items based in each case on their fair values. The excess of the purchase price over the estimated fair value of net assets acquired is recorded as goodwill. The Company generally uses independent appraisers to assist with the estimates and methodologies used such as a replacement cost approach, or
an income approach or excess earnings approach. Factors considered by the Company in its analysis include considering current market conditions and costs to construct similar facilities. The Company also considers information obtained about each
facility as a result of its pre-acquisition due diligence in estimating the fair value of the tangible and intangible assets and liabilities acquired or assumed. In estimating the fair value, the Company also
establishes estimates of energy production, current in-place and market power purchase rates, tax credit arrangements and operating and maintenance costs. A change in any of the assumptions above, which are
subjective, could have a significant impact on the results of operations. The allocation of the purchase price directly affects the
following items in the consolidated financial statements:  

The amount of purchase price allocated to the various tangible and intangible assets, liabilities and non-controlling interests on the balance sheet;  

The amounts allocated to the value of favorable and unfavorable rate PPAs and REC agreements are amortized to
revenue over the remaining non-cancelable terms of the respective arrangement. The amounts allocated to all other tangible assets and intangibles are amortized to depreciation or amortization expense; and  

The period of time over which tangible and definite-lived intangible assets and liabilities are depreciated or
amortized varies, and thus, changes in the amounts allocated to these assets and liabilities will have a direct impact on the Companys results of operations. ASC 805 allows the acquirer to report provisional amounts and adjust them for a period of time up to one year after the acquisition date (the
measurement period) while the Company obtains information about the facts and circumstances that existed as of the acquisition date. When an acquired group of assets does not constitute a business, the transaction is accounted for as an asset acquisition. The Company
recognizes and measures the acquired assets based on the cost of the acquisitions, generally being the consideration transferred to the seller and typically includes the direct transaction costs related to the acquisition. The Company allocates the
total cost of acquisition to the individual assets acquired or liabilities assumed based on their relative fair values generally similar to the allocation of the purchase price in a business combination. No goodwill is recognized in an asset
acquisition. Assets Held for Sale The Company records assets held for sale at the lower of the carrying value or fair value less costs to sell. The following criteria are used
to determine if property is held for sale: (i) management has the authority and commits to a plan to sell the property; (ii) the property is available for immediate sale in its present condition; (iii) there is an active program to
locate a buyer and the plan to sell the property has been initiated; (iv) the sale of the property is probable within one year; (v) the property is being actively marketed at a reasonable price relative to its current fair value; and
(vi) it is unlikely that the plan to sell will be withdrawn or that significant changes to the plan will be made.  F-109




---

In determining the fair value of the assets less costs to sell, the Company considers
factors including current sales prices for comparable assets in the region, recent market analysis studies, appraisals and any recent legitimate offers. If the estimated fair value less costs to sell of an asset is less than its current carrying
value, the asset is written down to its estimated fair value less costs to sell. Due to uncertainties in the estimation process, it is reasonably possible that actual results could differ from the estimates used in the Companys historical
analysis. The Companys assumptions about project sale prices require significant judgment because the current market is highly sensitive to changes in economic conditions. The Company estimates the fair values of assets held for sale based on
current market conditions and assumptions made by management, which may differ from actual results and may result in additional impairments if market conditions deteriorate. When assets are classified as held for sale, the Company does not record depreciation or amortization for the respective renewable energy
facilities or intangibles. At December 31, 2019 and 2018, there were no assets held for sale. Stock-Based Compensation Stock-based compensation expense for all share-based payment awards to certain employees who provide services to the Company is based on the
estimated grant-date fair value. The Company recognizes these compensation costs on a straight-line basis over the requisite service period of the award, which is generally the award vesting term. For ratable awards, the Company recognizes
compensation costs for all grants on a straight-line basis over the requisite service period of the entire award. The Company recognizes the effect of forfeitures in compensation costs when they occur. Deferred Compensation Plan The
Company sponsors a retirement saving plan that qualifies as a deferred compensation plan under Section 401(k) of the Internal Revenue Code. Eligible U.S. employees may elect to defer a percentage of their qualified compensation for income tax
purposes through payroll deductions, and the Company matches a percentage of the contributions based on employees elective deferrals. The Companys total matching contribution expense under the arrangement was $0.5 million,
$0.6 million and $0.5 million for the years ended December 31, 2019, 2018 and 2017, respectively. Restructuring The Company accounts for restructuring costs in accordance with ASC 712 and ASC 420, as applicable. In connection with the consummation of the
Merger and the relocation of the Companys headquarters to New York, New York, the Company announced a restructuring plan that went into effect upon the closing of the Merger. The Company recognized $0.1 million and $3.7 million of
severance and transition bonus costs related to this restructuring within general and administrative expenses in the consolidated statements of operations for the years ended December 31, 2019, and 2018. Severance and transition bonus payments
were $0.4 million and $5.5 million during the years ended December 31, 2019, and 2018. Recently Adopted Accounting
StandardsAdditional Guidance Adopted in 2019 In October 2018, the FASB issued ASU
No. 2018-16, Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge
Accounting Purposes. This ASU expands the list of United States (U.S.) benchmark interest rates permitted in the application of hedge accounting by adding the SOFR as a permissible U.S. benchmark rate. The Company does not have any
derivative instruments indexed to SOFR as a benchmark interest rate, accordingly, the adoption of ASU No. 2018-16 as of January 1, 2019 did not have an impact on the Companys consolidated
financial statements. Recently Issued Accounting Standards Not Yet Adopted In June 2016, the FASB issued ASU 2016-13, Financial Instruments  Credit Losses (Topic 326), to
provide financial statement users with more useful information about the current expected credit losses (CECL). This ASU changes how entities measure credit losses on financial instruments and the timing of when such losses are
recognized by utilizing a lifetime expected credit loss measurement. The guidance is effective for fiscal years and interim periods within those years beginning after January 1, 2020. The Company does not expect the adoption of Topic 326 to
have a material impact on its results of operations.  F-110

In August 2018, the FASB issued ASU
No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework  Changes to the Disclosure Requirements for Fair Value Measurement. This ASU removes some disclosure requirements, modifies
others, and adds some new disclosure requirements. The guidance is effective January 1, 2020, with early adoption permitted. The Company does not expect the effect of the new guidance to be material on its consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-15, Intangibles  Goodwill and Other
 Internal-Use Software (Subtopic 350-40) Customers Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract.
This ASU amends the definition of a hosting arrangement and requires a customer in a cloud computing arrangement that is a service contract to follow the internal use software guidance in ASC 350-402 to
determine which implementation costs to capitalize as assets. Capitalized implementation costs are amortized over the term of the hosting arrangement, beginning when the module or component of the hosting arrangement is ready for its intended use.
The guidance is effective January 1, 2020, with early adoption permitted. The Company does not expect the effect of the new guidance to be material on its consolidated financial statements. In October 2018, the FASB issued ASU No. 2018-17, Consolidation (Topic 810): Targeted
Improvements to Related Party Guidance for Variable Interest Entities. The amendments in this ASU require reporting entities to consider indirect interests held through related parties under common control for determining whether fees paid to
decision makers and service provider are variable interests. These indirect interests should be considered on a proportional basis rather than as the equivalent of a direct interest in its entirety (as currently required in U.S. GAAP). The guidance
is effective January 1, 2020, with early adoption permitted. Entities are required to apply the amendments in this guidance retrospectively with a cumulative-effect adjustment to retained earnings at the beginning of the earliest period
presented. The Company does not expect the effect of the new guidance to be material on its consolidated financial statements. In
December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The amendments in this ASU simplify the accounting for income taxes by removing
certain exceptions to the general principles in Topic 740, Income Taxes. The amendments also improve consistent application or and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. The guidance is
effective January 1, 2021, with early adoption permitted. The Company does not expect the effect of the new guidance to be material on its consolidated financial statements. 3. ACQUISITIONS AND DIVESTITURES 2019 Acquisitions (i) WGL Acquisition On September 26, 2019, TerraForm Arcadia Holdings, LLC, a Delaware limited liability company and a wholly-owned subsidiary of
the Company (TerraForm Arcadia), completed the acquisition of an approximately 320 MW distributed generation portfolio of renewable energy facilities in the United States from subsidiaries of AltaGas Ltd., a Canadian corporation
(AltaGas), for a purchase price of $720.0 million, plus $15.1 million for working capital. The acquisition was pursuant to a membership interest purchase agreement (the Purchase Agreement) dated July 19, 2019,
entered into by TerraForm Arcadia, WGL Energy Systems, Inc., a Delaware corporation (WGL), and WGSW, Inc., a Delaware corporation (WGSW, and together with WGL, the Sellers), both subsidiaries of AltaGas (the
WGL Acquisition). Pursuant to the Purchase Agreement, the ownership of certain projects for which the Sellers had not yet received the required third party consents or had not completed construction as of the closing date (the
Delayed Projects) were to be transferred to the Company once such third party consents were received or construction was completed, subject to certain terms and conditions. The Delayed Projects represented 11.6 MW of the combined
nameplate capacity of the acquired renewable energy facilities as of December 31, 2019. The purchase price allocated to the Delayed Projects based on the Purchase Agreement was $24.8 million, and is presented as Deposit on acquisitions on
the consolidated balance sheets. In the event that the title to certain Delayed Projects is not transferred to the Company within a certain period of time, the Company is entitled to a full refund of the value of these projects based on the Purchase
Agreement. The Company funded the purchase price and the related initial costs of the WGL Acquisition with the net proceeds of
$475.0 million Bridge Facility and the remainder from draws on the Revolver. See Note 10. Long-term Debt for additional details.  F-111

The Company accounted for the WGL Acquisition under the acquisition method of accounting for
business combinations. The final accounting has not been completed since the evaluation necessary to assess the fair values of acquired assets and assumed liabilities is still in process. The additional information needed by the Company to finalize
the measurement of these provisional amounts include, but not limited to, additional information regarding certain energy markets in the United States, the estimation of the removal costs for the acquired assets, the completion of the transfer of
the Delayed Projects, and the assessment of the incremental borrowing rate for operating leases. The provisional amounts for this business combination are subject to revision until these evaluations are completed. The preliminary allocation of the acquisition-date fair values of assets, liabilities and
non-controlling interests pertaining to this business combination as of December 31, 2019, were as follows:  (In thousands)

The Company acquired cash and cash equivalents of $3.4 million as of the acquisition date. The acquired non-financial assets primarily represent an estimate of the fair
value of the acquired renewable energy facilities and intangible assets from PPAs using the cost and income approach. Key inputs used to estimate fair value included forecasted power pricing, operational data, asset useful lives and a discount rate
factor reflecting current market conditions at the time of the acquisition. These significant inputs are not observable in the market and thus represent Level 3 measurements, as defined in Note 13. Fair Value of Financial Instruments.
Refer below for additional disclosures related to the acquired finite-lived intangible assets. The results of operations from the
acquired entities are included in the Companys consolidated results since the date of acquisition. The operating revenues and net income related to the WGL Acquisition reflected in the consolidated statements of operations for the year ended
December 31, 2019, were $13.8 million and $0.1 million, respectively.  F-112

) (ii) X-Elio Acquisition On December 18, 2019, Cuanto De Luz, S.L.U., a wholly-owned subsidiary of the Company, completed the acquisition of approximately 45 MW
utility-scale solar photovoltaic power facilities in Spain, from subsidiaries of X-Elio Energy, S.L., a Spanish corporation (the X-Elio Acquisition), for a
total purchase price of 63.8 million (equivalent to $71.1 million at the date of the acquisition). The Company funded the acquisition with a portion of the net proceeds of the utility-scale wind
non-recourse borrowing refinancing and cash available on hand. See Note 10. Long-term Debt for additional details. These facilities are regulated under the Spanish framework for renewable power, with
approximately 21 years of remaining regulatory life. This transaction was accounted for as an acquisition of assets, whereby the Company acquired approximately $186.5 million renewable energy facilities, and $54.8 million intangible assets
attributable to licensing contracts in-place from the acquired solar facilities using the cost and income approach. (iii) Acquisition of 15.1 MW Distributed Generation Assets During the year ended December 31, 2019, the Company acquired four distributed generation facilities located in the U.S. with a combined
nameplate capacity of 15.1 MW from third parties for a total purchase price of $24.0 million plus working capital adjustments. The facilities are contracted under long-term PPAs with municipal offtakers. This transaction was accounted for as an
acquisition of assets. 2018 Acquisitions (i) Saeta Acquisition On
February 7, 2018, the Company announced that it intended to launch a voluntary tender offer (the Tender Offer) to acquire 100% of the outstanding shares of Saeta, a Spanish renewable power company with then over 1,000 MW of solar
and wind facilities (approximately 250 MW of solar and 778 MW of wind) located primarily in Spain. The Tender Offer was for 12.20 in cash per share of Saeta. On June 8, 2018, the Company announced that Spains National Securities
Market Commission confirmed an over 95% acceptance of shares of Saeta in the Tender Offer (the Tendered Shares). On June 12, 2018, the Company completed the acquisition of the Tendered Shares for total aggregate consideration of
$1.12 billion and the assumption of $1.91 billion of project-level debt. Having acquired 95.28% of the shares of Saeta, the Company then pursued a statutory squeeze out procedure under Spanish law to procure the remaining approximately
4.72% of the shares of Saeta for $54.6 million.  F-113




---

The Company funded the $1.12 billion purchase price of the Tendered Shares with
$650.0 million of proceeds from the private placement of its Common Stock to Orion Holdings and BBHC Orion Holdco L.P. as discussed in Note 16.Stockholders Equity, along with approximately $471 million from
its existing liquidity, including (i) the proceeds of a $30.0 million draw on its Sponsor Line (as defined in Note 10. Long-term Debt), (ii) a $359.0 million as part of a draw on the Companys Revolver (as defined
in Note 10. Long-term Debt), and (iii) approximately $82 million of cash on hand. The Company funded the purchase of the remaining approximately 4.72% non-controlling interest in Saeta
using $54.6 million of the total proceeds from an additional draw on its Sponsor Line. The Company accounted for the acquisition of
Saeta under the acquisition method of accounting for business combinations. The purchase accounting for the Saeta acquisition, including assignment of goodwill to reporting units, was finalized as of June 30, 2019. The final allocation of the
acquisition-date fair values of assets, liabilities and redeemable non-controlling interests pertaining to this business combination as of December 31, 2019, was as follows:  (In thousands)

The excess purchase price over the estimated fair value of net assets acquired of $133.3 million was
recorded as goodwill, with $103.8 million assigned to the Regulated Solar and Wind segment and $29.5 million assigned to the Wind segment. See Note 7. Intangible Assets, Net and GoodwillandNote 23. Segment Reporting for
additional details. (2)
The fair value of the non-controlling interests was determined using a
market approach using a quoted price for the instrument. As discussed above, the Company acquired the remaining shares of Saeta pursuant to a statutory squeeze out procedure under Spanish law, which closed on July 2, 2018. The quoted price for
the purchase of the non-controlling interest was the best indicator of fair value and was supported by a discounted cash flow technique. (3)
The Company acquired cash and cash equivalents of $187.2 million and restricted cash of $95.1 million
as of the acquisition date. The acquired non-financial assets primarily
represent estimates of the fair value of acquired renewable energy facilities and intangible assets from licensing agreements using the cost and income approach. Key inputs used to estimate fair value included forecasted power pricing, operational
data, asset useful lives, and a discount rate factor reflecting current market conditions at the time of the acquisition. These significant inputs are not observable in the market and thus represent Level 3 measurements (as defined in Note
13. Fair Value of Financial Instruments). Refer below for additional disclosures related to the acquired finite-lived intangible assets. The results of operations of Saeta are included in the Companys consolidated results since the date of acquisition for the year ended
December 31, 2018, and for the entire year ended December 31, 2019. The operating revenues and net income of Saeta reflected in the consolidated statements of operations for the year ended December 31, 2019 were $407.1 million
and $57.6 million, respectively, and $221.2 million and $38.2 million for the year ended December 31, 2018, respectively.  F-114

Intangibles at Acquisition Date The Company attributed intangible asset value to licensing contracts in-place from solar and wind
facilities. These intangible assets are amortized on a straight-line basis over the estimated remaining useful life of the facility from the Companys acquisition date. The following table summarizes the estimated fair value and weighted

For purposes of this disclosure, the weighted average amortization period is determined based on a weighting of
the individual intangible fair values against the total fair value for each major intangible asset and liability class. Out-of-Period Adjustments During the preparation of the
Companys consolidated financial statements for the year ended December 31, 2019, management discovered errors related to the Saeta business combination as included in the Companys consolidated condensed financial statements for the
year ended December 31, 2018, included in the previously filed Annual Report on Form 10-K for the related period, and the unaudited consolidated condensed financial statements for the periods ended
March 31, 2019, June 30, 2019, and September 30, 2019, as included in the previously filed Quarterly Reports on Form 10-Q for the related periods. Specifically, the Company allocated the entire value
of $258.3 million of acquired projects within the International Wind operating segment as intangible assets without an allocation to renewable energy facilities. Additionally, the Company overstated the estimated fair value of assumed non-recourse long-term project debt as of June 30, 2019, and September 30, 2019, by approximately $28.5 million. The correction of these errors resulted in a $258.3 million increase in renewable
energy facilities, net, a $258.3 million decrease in intangible assets, a $28.5 million decrease in long-term debt, a $22.0 million decrease in goodwill, and a $6.5 million increase in deferred tax liabilities. The correction did
not have a material impact on the previously reported amounts of net loss, and comprehensive loss, and did not have any impact on the previously reported consolidated cash flows from operating, investing, or financing activities. The Company evaluated the errors and, based on an analysis of quantitative and qualitative factors, determined that the related impact was not
material to the Companys consolidated financial statements for any prior period. Therefore, amendments to the previously filed reports were not required. Unaudited Pro Forma Supplementary Data The unaudited pro forma supplementary data presented in the table below shows the effect of the Saeta acquisition, as if the transaction had
occurred on January 1, 2017. The pro forma net loss includes interest expense related to incremental borrowings used to finance the transaction and adjustments to depreciation and amortization expense for the valuation of renewable energy
facilities and intangible assets. The pro forma net loss for the year ended December 31, 2019, excludes the impact of acquisition related costs disclosed below. The unaudited pro forma supplementary data is provided for informational purposes
only and should not be construed to be indicative of the Companys results of operations had the acquisition been consummated on the date assumed or of the Companys results of operations for any future date.  (In thousands)

Acquisition Costs Total Acquisition costs incurred by the Company for the year ended December 31, 2019, were $4.7 million. Costs related to affiliates
included in these balances were $0.9 million. Acquisition costs incurred by the Company for the year ended December 31, 2018 were $14.6 million. Costs related to affiliates included in these balances were $6.9 million. These
costs are reflected as acquisition costs and acquisition costsaffiliate (see Note 21. Related Parties) in the consolidated statements of operations and are excluded from the unaudited pro forma net loss amount disclosed above. 2019 Divestiture (i) Sale of Six
Distributed Generation Facilities in the United States On December 20, 2019, the Company sold six distributed generation
facilities in the United States, with a combined nameplate capacity of 6.0 MW, for a net consideration of $9.5 million. The Company recognized a net gain of $2.3 million representing the difference between the net proceeds from the sale
and the net carrying amount of assets sold and liabilities extinguished, was recorded in the consolidated statement of operations for the year ended December 31, 2019 within the gain on sale of renewable energy facilities. 2017 Divestitures (i) U.K. Portfolio Sale On May 11, 2017, the Company announced that it completed its sale of substantially all of its portfolio of solar power plants
located in the United Kingdom (24 operating projects representing an aggregate 365.0 MW, the U.K. Portfolio) to Vortex Solar UK Limited, a renewable energy platform managed by the private equity arm of EFG Hermes, an investment bank. The
Company received approximately $214.1 million of proceeds from the sale, which was net of transaction expenses of $3.9 million and distributions taken from the U.K. Portfolio after announcement and before closing of the sale. The Company
also disposed of $14.8 million of cash and cash equivalents and $21.8 million of restricted cash as a result of the sale. The proceeds were used for the reduction of the Companys indebtedness (a $30.0 million prepayment for a non-recourse portfolio term loan and the remainder was applied towards revolving loans outstanding under its senior secured corporate-level revolving credit facility). The sale also resulted in a reduction in the
Companys non-recourse project debt by approximately £301 million British pounds sterling at the U.K. Portfolio level. The Company recognized a gain on the sale of $37.1 million, which is
reflected within Gain on sale of renewable energy facilities in the consolidated statements of operations for the year ended December 31, 2017. The Company retained one 11.1 MW solar project in the United Kingdom. (ii) Residential Portfolio Sale In 2017, the Company closed on the sale of 100% of the membership interests of Enfinity Colorado DHA 1, LLC, a Colorado limited liability
company that owned and operated 2.5 MW of solar installations situated on the roof of public housing units located in Colorado and owned by the Denver Housing Authority, and 100% of the membership interests of TerraForm Resi Solar Manager, LLC, a
subsidiary of the Company that owned and operated 8.9 MW of rooftop solar installations, to Greenbacker Residential Solar II, LLC. The Company received proceeds of $7.1 million during 2017 as a result of the sale of these companies and also
disposed of $0.6 million of cash and cash equivalents and $0.8 million of restricted cash. There was no additional loss recognized during 2017 as a result of these sales.  F-116

Contract balances and performance obligations The Company recognizes accounts receivable when its right to consideration from the performance of services becomes unconditional. The Company
establishes an allowance for doubtful accounts to adjust its receivables to amounts considered to be ultimately collectible and charges to the allowance are recorded within general and administrative expenses in the consolidated statements of
operations. The Companys allowance is based on a variety of factors, including the length of time receivables are past due, significant one-time events, the financial health of its customers and
historical experience. As of December 31, 2019 and 2018, the Companys receivable balances related to PPA contracts with solar and wind customers were approximately $104.1 million and $83.5 million, respectively. Trade
receivables for PPA contracts are reflected within accounts receivable, net in the consolidated balance sheets. The Company typically receives payment within 30 days for invoiced PPA revenue. Energy revenues yet to be earned under these contracts are expected to be recognized between 2020 and 2043. The Company applies the practical
expedient in Topic 606 to its bundled PPA contract arrangements, and accordingly, does not disclose the value of unsatisfied performance obligations for contracts for which it recognizes revenue at the amount to which it has the right to invoice for
services performed. As of December 31, 2019 and December 31, 2018, other liabilities in the consolidated balance sheets
included deferred revenue comprising of $8.4 million and $8.8 million upfront government incentives, respectively, and $1.8 million and $4.9 million contract liabilities related to performance obligations that have not yet been
satisfied, respectively. These contract liabilities represented advanced customer receipts primarily related to future REC deliveries that are recognized into revenue under Topic 606. The amount of revenue recognized during the year ended
December 31, 2019 and 2018, related to contract liabilities was $3.1 million and $1.3 million, respectively. 5. CASH AND CASH EQUIVALENTS Cash and cash equivalents include all cash balances and money market funds, including restricted cash, with original maturity periods of three
months or less when purchased. As of December 31, 2019 and December 31, 2018, cash and cash equivalents included $138.5 million and $177.6 million, respectively, of unrestricted cash held at project-level subsidiaries, which was
available for project expenses but not available for corporate use. Reconciliation of Cash and Cash Equivalents and Restricted Cash as Presented in
the Consolidated Statements of Cash Flows The following table provides a reconciliation of cash and cash equivalents and

respectively, of long-term restricted cash to current as of December 31, 2019, and 2018, consistent with the corresponding debt classification, as the restrictions that required the cash balances to be classified as long-term restricted cash

As discussed in Note 2. Summary of Significant Accounting Policies and Note 8. Leases, on
January 1, 2019, the Company recognized $262.1 million right-of-use of assets related to operating leases as a result of the adoption of Topic 842, which is
included within renewable energy facilities. The amount of right-of-use of assets as of December 31, 2019 was $288.3 million. Depreciation expense related to renewable energy facilities was $325.1 million, $270.4 million and $212.6 million for the years
ended December 31, 2019, 2018 and 2017, respectively. Sale of Assets On December 20, 2019, the Company sold six distributed generation facilities in the United States, with a combined nameplate capacity of
6.0 MW, for a net consideration of $9.5 million. The Company recognized a net gain of $2.3 million, representing the difference between the net proceeds from the sale and the net carrying amount of assets sold and liabilities extinguished,
in the consolidated statement of operations for the year ended December 31, 2019, within Gain on sale of renewable energy facilities. Impairment Assessment During the
year ended December 31, 2019, the Company identified opportunities to repower two wind power plants in the Northeast with a combined nameplate capacity of 160 MW by replacing certain components of the wind turbines with newer equipment while
preserving the existing towers, foundation and balance of plant. The Company views repowering activities as opportunities to increase efficiency and extend the useful lives of existing renewable energy facilities. The Company performed impairment
testing for these two wind power plants and did not record any impairment losses since it was determined that the expected undiscounted cash flows were greater than the net carrying amount of the related renewable energy facilities of
$79.4 million as of December 31, 2019. If the Company determines to move forward with the repowering activities for one or both of these wind plants during the year 2020, the Company will revise the estimated remaining useful lives of
certain components of the renewable energy facilities that will be replaced in the repowering activities and accelerate the recognition of depreciation expense to no later than the removal date. The Company had a REC sales agreement expiring on December 31, 2021, with a customer within a distributed generation portfolio, and on
March 31, 2018, the customer filed for protection under Chapter 11 of the U.S. Bankruptcy Code. The potential replacement of this contract would likely result in a significant decrease in expected revenues for this operating project. The
Companys analysis indicated that the bankruptcy filing was a triggering event to perform an impairment evaluation, and the carrying amount of $19.5 million as of March 31, 2018 was no longer considered recoverable based on an
undiscounted cash flow forecast. The Company estimated the fair value of the operating project at $4.3 million as of March 31, 2018 and recognized an impairment charge of $15.2 million equal to the difference between the carrying
amount and the estimated fair value, which is reflected within impairment of renewable energy facilities in the consolidated statements of operations for the year ended December 31, 2018. The Company used an income approach methodology of
valuation to determine fair value by applying a discounted cash flow method to the forecasted cash flows of the operating project, which was categorized as a Level 3 fair value measurement due to the significance of unobservable inputs. Key
estimates used in the income approach included forecasted power and incentive prices, customer renewal rates, operating and maintenance costs and the discount rate. The Company sold 0.3 MW of residential assets (that were not classified as held for sale as of December 31, 2016) during the third
quarter of 2017. These assets did not meet the criteria for held for sale classification as of June 30, 2017 but the Company determined that certain impairment indicators were present and as a result recognized an impairment charge of $1.4
million within impairment of renewable energy facilities in the consolidated statements of operations for the year ended December 31, 2017.  F-119

432,660 The operating revenues from delivering electricity and the related products from owned solar and wind
renewable energy facilities under PPAs in which the Company is the lessor, the majority of which is variable in nature, is recognized when electricity is delivered and is accounted for as rental income under the lease standard. The Company
determines if an arrangement is a lease at contract inception, and if so, includes both lease and non-lease components as a single component and accounts for it as a lease. The Companys PPAs do not
contain any residual value guarantees or material restrictive covenants. The Company manages its risk associated with the residual value of its leased assets by retaining the ability to sell RECs through REC sale agreements. As a result of the
adoption ASC 842 on January 1, 2019, the Company does not expect the future PPAs that it will enter into to meet the definition of a lease. See Note 2.

amounts of asset retirement obligations and the corresponding renewable energy facilities. The Company also recorded an adjustment to increase the previously reported accretion and depreciation expense by $3.3 million and $3.7 million,
respectively, as a result of this change. The Company had recorded an adjustment during the fourth quarter of 2018, which resulted in a $15.7 million reduction in the Companys asset retirement obligations and the corresponding renewable
energy facilities carrying amounts as of December 31, 2018. The Company also recorded an adjustment during the fourth quarter of 2018 to reduce previously reported accretion and depreciation expense by $6.3 million as a result of
this change. The Company evaluated these adjustments and, based on an analysis of quantitative and qualitative factors, determined that the related impact was not material to the Companys consolidated financial statements for any prior period. The Company did not have any assets that were legally restricted for the purpose of settling the Companys asset
retirement obligations as of December 31, 2019, 2018 and 2017. 10. LONG-TERM DEBT Long-term debt consisted of the following:  As of December 31,

of the principal amount. On June 11, 2015, Terra Operating LLC issued an additional $150.0 million of 5.875% senior notes due 2023 (collectively, with the $800.0 million initially issued, the Old Senior Notes due 2023).
The offering price of the additional $150.0 million of notes was 101.5% of the principal amount. On July 17, 2015, Terra Operating LLC issued $300.0 million of 6.125% senior notes due 2025 at an offering price of 100% of the principal
amount (the Senior Notes due 2025). On December 12, 2017, Terra Operating LLC issued $500.0 million of 4.25% senior
notes due 2023 at an offering price of 100% of the principal amount (the Senior Notes due 2023) and $700.00 million of 5.00% senior notes due 2028 at an offering price of 100% of the principal amount (the Senior Notes due
2028). Terra Operating LLC used the net proceeds of the Senior Notes due 2023 and the Senior Notes due 2028 to redeem, in full, its Old Senior Notes due 2023, of which $950.0 million remained outstanding, at a redemption price that
included a prepayment penalty of $50.7 million, plus accrued and unpaid interest, and to repay $150.0 million of revolving loans outstanding under the Revolver, as described below. As a result of the extinguishment of the Old Senior Notes
due 2023, the Company recognized a $72.3 million loss on extinguishment of debt during the year ended December 31, 2017, consisting of the $50.7 million prepayment penalty and the write-off of
$21.6 million of unamortized deferred financing costs and debt discounts as of the redemption date. On October 16, 2019, Terra
Operating LLC issued $700.0 million aggregate principal amount of 4.75% senior notes due on January 15, 2030, at an offering price of 100% of the principal amount (the Senior Notes due 2030 and, together
with the Senior Notes due 2023 and the Senior Notes due 2028, the Senior Notes), in an unregistered offering pursuant to Rule 144A under the Securities Act. Terra Operating LLC used the net proceeds from the Senior Notes due 2030 to
(i) redeem, in full, the Senior Notes due 2025, of which $300.0 million remained outstanding, at a redemption price that included a prepayment penalty of $18.4 million, plus accrued interest, (ii) redeem, in full, the
Companys Term Loan (as defined below), of which $343.9 million remained outstanding plus accrued interest, (iii) redeem, in full, derivative liabilities related to interest rate swaps with hedge counterparties of which
$8.8 million remained outstanding, and (iii) pay for the fees and expenses related to the issuance. The Senior Notes are senior
obligations of Terra Operating LLC and are guaranteed by Terra LLC and each of Terra Operating LLCs subsidiaries that guarantee the Revolver (as defined below) or certain other material indebtedness of Terra Operating LLC or Terra LLC. Each
series of the Senior Notes rank equally in right of payment with all existing and future  F-125

senior indebtedness of Terra Operating LLC, including the Revolver, senior in right of payment to any future subordinated indebtedness of Terra Operating LLC, and effectively subordinated to all
borrowings under the Revolver, which are secured by substantially all of the assets of Terra Operating LLC and the guarantors of the Senior Notes. At its option, Terra Operating LLC may redeem some or all of each series of the Senior Notes at any time or from time to time before their
maturity. If Terra Operating LLC elects to redeem the Senior Notes due 2023 prior to October 31, 2022, the Senior Notes due 2028 before July 31, 2027, or the Senior Notes due 2030 before January 15, 2025, Terra Operating LLC would be
required to pay a prepayment penalty as set forth in the applicable indenture. If Terra Operating LLC elects to redeem the Senior Notes due 2030 between January 15, 2025 and January 14, 2028, Terra Operating LLC would be required to pay a
call premium as set forth in the applicable indenture. If Terra Operating LLC elects to redeem the Senior Notes due 2023, the Senior Notes due 2028, or the Senior Notes due 2030 on or after these respective dates, Terra Operating LLC would be
required to pay a redemption price equal to 100% of the aggregate principal amount of the Senior Notes redeemed plus accrued and unpaid interest thereon. If certain change of control triggering events occur in the future, Terra Operating LLC must
offer to repurchase all of each series of the Senior Notes at a price equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the repurchase date. Term Loan On November 8, 2017,
Terra Operating LLC entered into a 5-year $350.0 million senior secured term loan (the Term Loan) and used the net proceeds to repay outstanding borrowings under a non-recourse project-level term debt and $50.0 million of revolving loans outstanding under the Revolver. The Term Loan originally bore interest at a rate per annum equal to, at Terra Operating LLCs
option, either (i) a base rate plus a margin of 1.75% or (ii) a reserve adjusted Eurodollar rate plus a margin of 2.75%, and is secured and guaranteed equally and ratably with the Revolver. The Term Loan provided for voluntary prepayments,
in whole or in part, subject to notice periods. There were no prepayment penalties or premiums other than customary breakage costs after the six-month anniversary of the closing date. Within the first six
months following the closing date, a prepayment premium of 1.00% would apply to any principal amounts that were prepaid. On May 11, 2018, Terra Operating LLC entered into an amendment to the Term Loan, whereby the interest rate was reduced
by 0.75% per annum. The Company recognized a $1.5 million loss on extinguishment of debt during the year ended December 31, 2018, as a result of this amendment representing write-offs of certain deferred debt financing costs. On
March 8, 2019, the Company entered into interest rate swap agreements with counterparties to hedge the cash flows associated with the interest payments on the entire principal of the Term Loan, paying an average fixed rate of 2.54%. In return,
the counterparties agreed to pay the variable interest payments due to the lenders until maturity. On October 17, 2019, Terra Operating LLC repaid, in full, the amounts outstanding, including the accrued interest, under the Term Loan using the
proceeds of the offering of the Senior Notes due 2030. The Company recognized a loss on extinguishment of $4.0 million for the year ended December 31, 2019, representing write-offs of deferred debt financing costs. Revolver On October 17, 2017, Terra
Operating LLC entered into a new senior secured revolving credit facility (the Revolver) in an initial amount of $450.0 million, available for revolving loans and letters of credit, and maturing in October 2021. All
outstanding amounts originally bore interest at a rate per annum equal to, at Terra Operating LLCs option, either (i) a base rate plus a margin ranging between 1.25% to 2.00% or (ii) a reserve adjusted Eurodollar rate plus a margin
ranging between 2.25% to 3.00%. In addition to paying interest on outstanding principal under the Revolver, Terra Operating LLC is required to pay a standby fee in respect of the unutilized commitments thereunder, payable quarterly in arrears. This
standby fee ranges between 0.375% and 0.50% per annum. The Revolver provides for voluntary prepayments, in whole or in part, subject to notice periods. There are no prepayment penalties or premiums other than customary breakage costs. On
February 6, 2018, Terra Operating LLC entered into an amendment to increase the facility limit to $600.0 million. On October 5, 2018, Terra Operating LLC entered into an amendment to (i) reduce the interest rate by 0.75% per
annum, and (ii) extend the maturity date of the Revolver to October 2023. The Revolver currently bears interest at a rate equal to, at Terra Operating LLCs option, either (i) a reserve adjusted Eurodollar rate plus an applicable
margin ranging from 1.50% to 2.25% per annum, or (ii) a base rate plus an applicable margin ranging from 0.50% to 1.25% per annum. The Company did not incur additional debt or receive any proceeds in connection with the October 5, 2018
amendment. Under the Revolver, each of Terra Operating LLCs existing and subsequently acquired or organized domestic restricted
subsidiaries (excluding non-recourse subsidiaries) and Terra LLC are or will become guarantors. The Revolver, each guarantee and any interest rate, currency hedging or hedging of REC obligations of Terra
Operating LLC or any guarantor owed to the administrative agent, any arranger or any lender under the Revolver is secured by first priority security interests in (i) all of Terra Operating LLCs, each guarantors and certain
unencumbered non-recourse subsidiaries assets, (ii) 100% of the capital stock of each of Terra Operating LLC and its domestic restricted subsidiaries and 65% of the capital stock of Terra Operating
LLCs foreign restricted subsidiaries and (iii) all intercompany debt. The Revolver is secured equally and ratably with the Term Loan.  F-126




---

On October 8, 2019, Terra Operating LLC entered into an amendment to the Revolver
agreement (the Upsize Amendment) whereby (i) the aggregate size of the commitments to make revolving loans (Revolving Loans) under the Revolver was increased by $200.0 million to $800.00 million,
shared ratably among the lenders of October 8, 2019, (ii) the aggregate size of the letter of credit facility under the Revolver was increased by $50.0 million to $300.0 million and (iii) the accordion feature of the Revolver,
which allows for further increases to the commitments to make Revolving Loans, was set at $150.0 million. Additionally, the Upsize Amendment extended the maturity date of the Revolver by one year to October 5, 2024. Sponsor Line Agreement On
October 16, 2017, TerraForm Power, Inc. entered into a credit agreement (the Sponsor Line) with Brookfield and one of its affiliates. The Sponsor Line establishes a $500.0 million secured revolving credit facility and provides
for the lenders to commit to making LIBOR loans to the Company during a period not to exceed three years from the effective date of the Sponsor Line (subject to acceleration for certain specified events). The Company may only use the revolving
Sponsor Line credit facility to fund all or a portion of certain funded acquisitions or growth capital expenditures. The Sponsor Line terminates, and all obligations thereunder become payable, no later than October 16, 2022. Borrowings under the Sponsor Line bear interest at a rate per annum equal to a LIBOR rate determined by reference to the costs of funds for
U.S. dollar deposits for the interest period relevant to such borrowing adjusted for certain additional costs, in each case plus 3.00% per annum. In addition to paying interest on outstanding principal under the Sponsor Line, the Company is
required to pay a standby fee of 0.50% per annum in respect of the unutilized commitments thereunder, payable quarterly in arrears. The Company is permitted to voluntarily reduce the unutilized portion of the commitment amount and repay outstanding
loans under the Sponsor Line at any time without premium or penalty, other than customary breakage costs. TerraForm Powers obligations under the Sponsor Line are secured by first-priority security interests in substantially all
assets of TerraForm Power, including 100% of the capital stock of Terra LLC, in each case subject to certain exclusions set forth in the credit documentation governing the Sponsor Line. Under certain circumstances, the Company may be required to
prepay amounts outstanding under the Sponsor Line. During the year ended December 31, 2018, the Company made two draws on the
Sponsor Line totaling $86.0 million. The Company used the proceeds to fund the acquisition of Saeta and were repaid in full as of December 31, 2018. The Company did not make any draws on the Sponsor Line during the years ended
December 31, 2019, and 2017. See Note 21. Related Parties for details. Covenants and Cross-defaults The terms of the Companys corporate-level debt agreements and indentures include customary affirmative and negative covenants and provide
for customary events of default, which include, among others, nonpayment of principal or interest and failure to timely deliver financial statements, including quarterly financial maintenance covenants for the Revolver. The occurrence of an event of
default for one corporate-level debt instrument could also cause a cross-default for the other corporate-level debt instruments, as described below. Pursuant to both the terms of the Revolver and the Term Loan, a default of more than $75.0 million of indebtedness (other than non-recourse indebtedness, and indebtedness under the Sponsor Line, which is an obligation of the Company), including under these respective agreements, would result in a cross-default under the respective
agreements that would permit the lenders holding more than 50% of the aggregate exposure under each to accelerate any outstanding principal amount of loans, terminate any outstanding letter of credit and terminate the outstanding commitments (as
applicable to each). Pursuant to the terms of the Senior Notes, a default of indebtedness that exceeds the greater of (i)
$100.0 million for the Senior Notes due 2023 and Senior Notes due 2028, and $140.0 million for the Senior Notes due 2030, or (ii) 1.5% of the Companys consolidated total assets (other than
non-recourse indebtedness and indebtedness under the Sponsor Line, which is an obligation of TerraForm Power), that is (i) caused by a failure to pay principal of, or interest or premium, if any, on such
indebtedness prior to the expiration of the grace period provided in such indebtedness on the date of such default or (ii) results in the acceleration of such indebtedness would give the trustee under the respective indentures or the holders of
at least 25% in the aggregate principal amount of the then outstanding Senior Notes under the respective indentures the right to accelerate any outstanding principal amount of loans and terminate the outstanding commitments under the respective
indentures.  F-127

An event of default of more than $75.0 million of indebtedness under the Revolver, Term
Loan and each series of the Senior Notes would trigger an event of default under the Sponsor Line that would permit the lenders to accelerate any outstanding principal amount of loans and terminate the outstanding commitments under the Sponsor Line. Non-recourse Long-term Debt Certain subsidiaries of the Company have incurred long-term non-recourse debt obligations related to
the renewable energy facilities that those subsidiaries own directly or indirectly. The indebtedness of these subsidiaries is typically secured by the renewable energy facilities or equity interests in subsidiaries that directly or indirectly hold
renewable energy facilities with no recourse to TerraForm Power, Terra LLC or Terra Operating LLC other than limited or capped contingent support obligations, which in aggregate are not considered material to the Companys business and
financial condition. In connection with these financings and in the ordinary course of its business, the Company and its subsidiaries observe formalities and operating procedures to maintain each of their separate existence and can readily identify
each of their separate assets and liabilities as separate and distinct from each other. As a result, these subsidiaries are legal entities that are separate and distinct from each of TerraForm Power, Terra LLC, Terra Operating LLC and the guarantors
under the Senior Notes due 2023, the Senior Notes due 2028, the Senior Notes due 2030, the Revolver and the Sponsor Line. 2019 United States Project
Financings On May 29, 2019, one of the Companys subsidiaries entered into a new
non-recourse debt financing agreement of $104.1 million senior secured term loan facility, and secured by approximately 137.7 MW of distributed generation solar power facilities located in
the U.S. that are owned by certain subsidiaries of the Company. The Company used the net proceeds of this debt to repay a portion of the Revolver and general corporate purposes. The debt bears interest at a rate per annum equal to three month LIBOR
plus an applicable margin of 200 basis points that increases by 12.5 basis points every four years until maturity. The debt matures on May 26, 2034, and amortizes on a fifteen-year sculpted amortization schedule. The Company entered into
interest rate swap agreements with counterparties to hedge the interest payments associated with the debt, paying a fixed rate of 2.3%. In return, the counterparties agreed to pay the variable interest payments to the lenders. On August 30, 2019, one of the Companys subsidiaries entered into a new
non-recourse debt financing agreement issuing $131.0 million of 3.2% senior notes secured by approximately 111 MW of utility-scale wind power plants located in the
United States that are owned by certain subsidiaries of the Company. The Company used the net proceeds of this debt to repay a portion of the balance outstanding under the Revolver. The senior secured notes mature on July 2, 2032 and amortize
on an approximately thirteen-year sculpted amortization schedule. On September 25, 2019, one of the Companys
subsidiaries entered into a $475.0 million new non-recourse senior term loan (Bridge Facility) secured by the approximately 320 MW portfolio of distributed generation power
facilities located in the United States that were acquired from subsidiaries of AltaGas. The Bridge Facility bears interest at a rate per annum equal to LIBOR plus an applicable margin of 100 basis points for the first six months, 150 basis points
for the following six months and 175 basis points thereafter. The Company used the net proceeds of this debt to fund a portion of the purchase price of the WGL Acquisition. See Note 3. Acquisitions and Divestitures for additional details. The
Bridge Facility matures on September 24, 2020. The Company has a one-year extension option and intends, through its subsidiaries, to complete a refinancing of the balance on a long-term basis before
maturity in a series of two or more transactions. The balance, net of a principal repayment and unamortized deferred financing costs, is included within non-current liabilities in the consolidated balance
sheets. On November 25, 2019, one of the Companys subsidiaries entered into a new
non-recourse debt financing agreement issuing $171.5 million of 3.55% senior notes secured by approximately 200.6 MW utility-scale wind power plants located in the United States. The Company used the net
proceeds of this debt to (i) redeem, in full, the outstanding balance of the non-recourse project term debt previously incurred by the subsidiary, of which $69.1 million remained outstanding plus
accrued and unpaid interest, (ii) redeem, in full, derivative liabilities related to interest rate swaps with hedge counterparties of which $9.8 million remained outstanding and (iii) pay for the fees and expenses related to the
issuance. The Company used the remaining proceeds for general corporate purposes. As a result of the extinguishment of the project-level debt, the Company recognized a $0.3 million loss on extinguishment of debt during the year ended
December 31, 2019, representing the write-off of unamortized debt discount as of the redemption date. The senior secured notes mature on May 1, 2039, and amortize on a twenty-year amortization
schedule.  F-128

2019 Spain Project Financings On December 10, 2019, five of the Companys subsidiaries completed a 235.8 million refinancing agreement (equivalent to
$264.4 million at the closing date) of certain non-recourse indebtedness associated with 236.0 MW utility-scale wind plants located in Spain (the Spanish Wind Term Loans). The Spanish Wind
Term Loans bear interest at a rate per annum equal to three months Euribor plus an applicable margin of 165 basis points that increases by 20 basis points every five years throughout maturity. The Spanish Wind Term Loans amortize on a sculpted
amortization schedule through their respective maturity dates through December 2033. The Company entered into interest rate swap agreements with counterparties to hedge approximately 80% of the cash flows associated with the debt, paying a fixed
rate of 1.55%. In return, the counterparties agreed to pay the variable interest payments to the lenders. The Company used the net proceeds of the refinancing to fund a portion of the purchase price of the
X-Elio Acquisition. On December 27, 2019, one of the Companys subsidiaries completed a
213.6 million refinancing agreement of certain non-recourse indebtedness, representing an upsize of approximately 42.0 million (equivalent to $239.5 million and $47.1 million at
the closing date, respectively), of certain non-recourse indebtedness associated with approximately 50.0 MW concentrated solar power facility located in Spain (the Spanish Solar Term Loans). The
Spanish Solar Term Loans consist of 146.4 million variable-rate tranche and 67.2 million fixed-rate tranche (equivalent to $164.2 million and $75.3 million, respectively). The variable-rate tranche bears interest at a
rate per annum equal to three months Euribor plus an applicable margin of 190 basis points that increases by 20 basis points every five years throughout the maturity in December of 2033. The fixed-rate tranche bears interest at a rate of 2.55% and
matures on June 30, 2035. The Spanish Solar Term Loans amortize on a sculpted amortization schedule through their respective maturity dates through 2035. The Company entered into interest rate swap agreements with counterparties to hedge
approximately 80% of the variable cash flows of the debt, paying an average fixed rate of 3.70%. In return, the counterparty agreed to pay the variable interest payments to the lenders. The Company used the net proceeds of the refinancing for
general corporate purposes. 2019 Uruguay Project Financing On April 30, 2019, two of the Companys subsidiaries completed a $204.0 million refinancing agreements of certain non-recourse indebtedness, representing a net upsize of approximately $57.5 million, associated with the Companys 95 MW of utility-scale wind plants located in Uruguay (the Uruguay Term
Loans). The Uruguay Term Loans consist of a $103.0 million Tranche A loan, a new $72.0 million Tranche B loan, and an additional $29.0 million senior secured term loan. Approximately 46% of the combined principal amount of the
Uruguay Term Loans bears a fixed interest rate of 2.6%, and the remainder bears interest at a rate per annum equal to six-month U.S. LIBOR plus an applicable margin that ranges from 1.94% to 2.94%. The Uruguay
Term Loans amortize on a sculpted amortization schedule through their respective maturity dates through December 2035. The Company entered into interest rate swap agreements with a counterparty to hedge greater than 90% of the cash flows associated
with the variable portion of the debt, paying a fixed rate of 2.78%. In return, the counterparty agreed to pay the variable interest payments to the lenders. The net proceeds of the refinancing were used to pay down a portion of the Revolver and
general corporate purposes. Indebtedness Assumed on Acquisition In connection with the X-Elio Acquisition, the Company assumed $151.7 million of project-level
debt secured by the renewable energy facilities of the related entities. The average interest rates applicable to this assumed indebtedness was 2.8%. As of December 31, 2019, the Company obtained all required change of control consents from the
lenders.  F-129

Financing Lease Obligations In certain transactions, the Company accounts for the proceeds of sale-leasebacks as financings, which are typically secured by the renewable
energy facility asset and its future cash flows from energy sales, with no recourse to Terra LLC or Terra Operating LLC under the terms of the arrangement. Non-recourse Debt Defaults As of December 31, 2019 and December 31, 2018, the Company reclassified $159.3 million and $166.4 million,
respectively, of non-recourse long-term indebtedness, net of unamortized deferred financing costs and debt discounts, to current in the consolidated balance sheets due to defaults remaining as of the
respective financial statements issuance dates. The defaults as of December 31, 2019 primarily consisted of indebtedness of the Companys renewable energy facility in Chile. The Company continues to amortize deferred financing costs and
debt discounts over the maturities of the respective financing agreements as before the violations, since the Company believes there is a reasonable likelihood that it will be, in due course, able to successfully negotiate waivers with the lenders
and/or cure existing defaults. The Companys management based this conclusion on (i) its past history of obtaining waivers and/or forbearance agreements with lenders, (ii) the nature and existence of active negotiations between the
Company and the respective lenders to secure waivers, (iii) the Companys timely servicing of these debt instruments and (iv) the fact that no non-recourse financing has been accelerated to date
and no project-level lender has notified the Company of such lenders election to enforce project security interests. See Note 5. Cash
and Cash Equivalentsfor discussion of corresponding restricted cash reclassifications to current as a result of these defaults. Modification
and Extinguishment of Debt Net loss on modification and extinguishment of debt includes prepayment penalties, the write-off of unamortized deferred financing costs and debt premiums or discounts, costs incurred in a debt modification that are not capitalized as deferred financing costs, other costs incurred in relation to debt
extinguishment, and any gain from the redemption of debt below its carrying amount. Loss on modification and extinguishment of debt, net in the consolidated statements of operations for the years ended December 31, 2019, 2018 and 2017, were
attributable to the following:  Year Ended December 31,(In thousands)

Prior to the consummation of the Merger on October 16, 2017, TerraForm Power owned
approximately 66% of Terra LLC and SunEdison owned approximately 34% of Terra LLC. On October 16, 2017, pursuant to the Settlement Agreement, SunEdison transferred its interest in Terra LLC to TerraForm Power. Since the date of this
transaction, TerraForm Power owns 100% of the capital and profits interest in Terra LLC, except for the IDRs which are owned by Brookfield IDR Holder. The Merger resulted in a change in control to occur subjecting TerraForm Powers loss
carryforwards to be limited for future usage under Internal Revenue Code Section 382. On December 31, 2018, the Company
executed a reorganization of its Capital Dynamics portfolio which resulted in no current tax impact by effectively moving the stock of the Capital Dynamics corporate entities up to TerraForm Power and then immediately contributing Capital Dynamics
project assets to Terra LLC. The Company recognized a deferred tax benefit of $20.1 million during the year ended December 31, 2018, resulting from an excess net deferred tax liability that was previously recognized by TerraForm Power
Holdings, Inc. as a separate taxpayer which is now expected to reverse in future periods as part of the U.S. federal and state tax consolidated group and provide a source of future taxable income to realize the Companys net operating loss
(NOL) carryforwards. For the years ended December 31, 2019 and December 31, 2018, the overall effective tax rate
was different than the statutory rate of 21% primarily due to the recording of a valuation allowance on certain income tax benefits attributed to the Company, losses allocated to non-controlling interests, the
2018 revaluation of deferred federal and state tax balances for TerraForm Power Holdings, Inc., and the effect of foreign and state taxes. For the year ended December 31, 2017, the overall effective tax rate was different from the statutory tax
rate of 35% primarily due to the recording of a valuation allowance on certain income tax benefits attributed to the Company, losses allocated to non-controlling interests, the 2017 revaluation of
deferred federal and state tax balances and the effect of foreign and state taxes. The tax effects of the major items recorded as
deferred tax assets and liabilities were as follows:  As of December 31,(In thousands)

178,849 For U.S. income tax purposes, Terra LLC is taxed as a U.S. partnership and controls the underlying renewable
energy facilities. Thus, the tax effects of temporary differences related to the Companys portfolio companies are captured within the net deferred tax liability for the investment in the partnership. At December 31, 2019, the Company has
gross NOL carryforwards of $2.29 billion in the U.S. and gross NOL carryforwards of $132.1 million in foreign jurisdictions that will both expire in tax years beginning in 2035. Of the $2.3 billion of gross NOL carryforwards generated
in the U.S., approximately $0.56 billion are limited and are expected to expire unused. For the remaining $1.73 billion, the Company does not believe it is more likely than not that it will generate sufficient taxable income to realize
this entire amount. Consequently, the Company has recorded a valuation allowance against its deferred tax assets, net of the deferred tax liability related to the Companys partnership investments that is expected to reverse within the NOL
carryforward period with the exception of certain NOL at its Canadian, Portuguese, Spanish and Uruguayan operations. The current year movement in the valuation allowance is related to losses generated in the current year as a result of the current
year operations and changes in the Companys tax accounting methods and the limitations on such U.S. Federal and State losses as a result of U.S. Tax Reform.  F-133

Prior to the acquisition of Saeta, the Companys foreign entities had cumulative
negative earnings and profits, therefore, those entities had no earnings to repatriate back to the U.S. Following the enactment of the Tax Act and the current year acquisition of Saeta, the Company does not assert the indefinite reinvestment related
to undistributed earnings of its foreign subsidiaries. The Company plans to utilize earnings generated by its foreign subsidiaries to make strategic acquisitions abroad and repatriate any excess earnings. The Companys management determined
there was no material deferred tax liabilities that needed to be recognized as of December 31, 2019. The 2017 Tax Act included a
provision to tax global intangible low tax income (GILTI) of foreign subsidiaries in excess of a standard rate of return. The Company will record expense related to GILTI in the period the tax is incurred. For the year ended
December 31, 2019, the Company was in an overall tested loss position for GILTI purposes and therefore has not included GILTI in its calculation of taxable loss. The U.S. Treasury has issued additional guidance through notices and final
regulations during 2019 which did not significantly impact the Companys interpretation of the 2017 Tax Act. The Company will continue to monitor developments as they occur. As of December 31, 2019 and 2018, the Company had not identified any uncertain tax positions for which a liability was required under ASC
740-10. 12. DERIVATIVES As part of its risk management strategy, the Company entered into derivative instruments which include interest rate swaps, foreign currency
contracts and commodity contracts to mitigate interest rate, foreign currency and commodity price exposures. If the Company elects to do so and if the instrument meets the criteria specified in ASC 815,Derivatives and Hedging, the
Company designates its derivative instruments as either cash flow hedges or net investment hedges. The Company enters into interest rate swap agreements in order to hedge the variability the of expected future cash interest payments. Foreign
currency contracts are used to reduce risks arising from the change in fair value of certain foreign currency denominated assets and liabilities. The objective of these practices is to minimize the impact of foreign currency fluctuations on
operating results. The Company also enters into commodity contracts to hedge price variability inherent in energy sales arrangements. The objectives of the commodity contracts are to minimize the impact of variability in spot energy prices and
stabilize estimated revenue streams. The Company does not use derivative instruments for trading or speculative purposes.  F-134

Fair value amounts are shown before the effects of counterparty netting adjustments. (2)
Represents the netting of derivative exposures covered by qualifying master netting arrangements. As of December 31, 2019 and December 31, 2018, the Company had posted letters of credit in the amount of
$15.0 million, as collateral related to certain commodity contracts. Certain derivative contracts contain provisions providing the counterparties a lien on specific assets as collateral. There was no cash collateral received or pledged as of
December 31, 2019 and December 31, 2018 related to the Companys derivative transactions. The Company elected to present
all derivative assets and liabilities on a net basis on the consolidated balance sheets as a right to set-off exists. The Company enters into International Swaps and Derivatives Association, Inc.
(ISDA) Master Agreements with its counterparties. An ISDA Master Agreement is an agreement that can govern multiple derivative transactions between two counterparties that typically provides for the net settlement of all, or a specified
group, of these derivative transactions through a single payment, and in a single currency, as applicable. A right to set-off typically exists when the Company has a legally enforceable ISDA Master Agreement.
No amounts were netted for commodity contracts as of December 31, 2019 or 2018 as each of the commodity contracts were in a gain position.  F-135

(5,117
) During the second quarter of 2018, the Company discontinued hedge accounting for a certain long-dated
commodity contract as it was no longer considered highly effective in offsetting the cash flows associated with the underlying risk being hedged. Long-term electricity prices in the related market declined significantly during the second quarter of
2018, causing the option component of the derivative contract to have an intrinsic value which negatively impacted the effectiveness assessment of the hedge relationship. Hedge accounting was prospectively discontinued effective April 1,
2018, with changes in fair value recorded in earnings. The gains in AOCI as of March 31, 2018 amounted to $44.3 million and $5.7 million of which were recorded in earnings during the three quarters following the discontinuation
of hedge accounting. The balance of the accumulated gains deferred in AOCI as of December 31, 2019 was $30.9 million will be amortized through earnings over the term of the contract, which expires in 2023, of which
$7.7 million will be amortized within the next 12 months. As discussed inNote 3. Acquisitions and Divestitures, the
Company consummated the sale of the U.K. Portfolio on May 11, 2017. As part of the sale agreement, Vortex Solar UK Limited assumed the debt and the associated interest rate swaps. As of the date of the sale, the remaining loss in AOCI
of $0.4 million was reclassified into interest expense, net, and the fair value of the interest rate swap liability of $23.4 million is reflected within gain on sale of renewable energy facilities in the consolidated
statements of operations for the year ended December 31, 2017. The interest expense amount reflected in the table above for the year ended December 31, 2017 primarily pertains to these interest rate swaps.  F-136

years ended December 31, 2018 and 2017, respectively. Derivatives Designated as Hedging Instruments Interest Rate Swaps The Company has
interest rate swap agreements to hedge certain variable rate non-recourse debt. These interest rate swaps qualify for hedge accounting and were designated as cash flow hedges. Under the interest rate swap
agreements, the Company pays a fixed rate and the counterparties to the agreements pay a variable interest rate. The change in the fair value of the components included in the effectiveness assessment of these derivatives is initially reported in
AOCI and subsequently reclassified to earnings in the periods when the hedged transactions affect earnings (the payment of interest). The amounts deferred in AOCI and reclassified into earnings during the years ended December 31, 2019, 2018 and
2017 related to these interest rate swaps are provided in the tables above. The loss expected to be reclassified into earnings over the next twelve months is approximately $6.9 million. The maximum term of outstanding interest rate swaps
designated as hedging instruments is 19 years. Foreign Currency Forward Contracts The Company uses foreign currency forward contracts to hedge portions of its net investment positions in certain subsidiaries with Euro
() and Canadian dollar (C$) functional currencies and to manage its foreign exchange risk. For instruments that are designated and qualify as hedges of net investment in foreign operations, the effective portion of the
net gains or losses attributable to changes in exchange rates are recorded in foreign currency translation adjustments within AOCI. The recognition in earnings of amounts previously recorded in AOCI is limited to circumstances such as complete or
substantial liquidation of the net investment in the hedged foreign operation.  F-137




---

Cash flows from derivative instruments designated as net investment hedges are classified as
investing activities in the consolidated statements of cash flows. As of December 31, 2019, the total notional amount of
foreign currency forward contracts designated as net investment hedges was 200 million and C$94 million. The maturity dates of these derivative instruments designated as net investment hedges range from 3 months
to 33 months. As of December 31, 2018, the total notional amount of foreign currency forward contracts designated as net investment hedges was 320 million and C$81.6 million. The maturity dates of these derivative
instruments designated as net investment hedges range from 3 months to 2 years. There were no foreign currency forward contracts designated as net investment hedges as of December 31, 2017. Commodity Contracts The Company has two
long-dated physically delivered commodity contracts that hedge variability in cash flows associated with the sales of power from certain wind renewable energy facilities located in Texas. One of these commodity contract qualifies for hedge
accounting and is designated as a cash flow hedge. The change in the fair value of the components included in the effectiveness assessment of this derivative is initially reported in AOCI and subsequently reclassified to earnings in the periods when
the hedged transactions affect earnings (the sale of electricity). The amounts deferred in AOCI and reclassified into earnings during the years ended December 31, 2019, 2018 and 2017 related to these commodity contracts are provided in the
tables above. The gain expected to be reclassified into earnings over the next twelve months is approximately $1.6 million. The maximum term of the outstanding commodity contract designated as a hedging instrument is 8 years. Derivatives Not Designated as Hedging Instruments Interest Rate Swaps The Company has
interest rate swap agreements that economically hedge the cash flows for non-recourse debt. These interest rate swaps pay a fixed rate and the counterparties to the agreements pay a variable interest rate. The
changes in fair value are recorded in interest expense, net in the consolidated statements of operations as these derivatives are not accounted for under hedge accounting. Foreign Currency Contracts The Company
has foreign currency forward and option contracts that economically hedge its exposure to foreign currency fluctuations. As these hedges are not accounted for under hedge accounting, the changes in fair value are recorded in loss (gain) on foreign
currency exchange, net in the consolidated statements of operations. Commodity Contracts The Company has commodity contracts that to economically hedge commodity price variability inherent in certain electricity sales arrangements.
If the Company sells electricity to an independent system operator market and there is no PPA available, it may enter into a commodity contract to hedge all or a portion of their estimated revenue stream. These commodity contracts require periodic
settlements in which the Company receives a fixed-price based on specified quantities of electricity and pays the counterparty a variable market price based on the same specified quantity of electricity. As these derivatives are not accounted for
under hedge accounting, the changes in fair value are recorded in operating revenues, net in the consolidated statements of operations. 13. FAIR VALUE OF FINANCIAL INSTRUMENTS The fair values of assets and liabilities are determined using either unadjusted quoted
prices in active markets (Level 1) or pricing inputs that are observable (Level 2) whenever that information is available and using unobservable inputs (Level 3) to estimate fair value only when relevant observable inputs are not available. The
Company uses valuation techniques that maximize the use of observable inputs. Assets and liabilities are classified in their entirety based on the lowest priority level of input that is significant to the fair value measurement. Where observable
inputs are available for substantially the full term of the asset or liability, the instrument is categorized in Level 2. If the inputs into the valuation are not corroborated by market data, in such instances, the valuation for these contracts
is established using techniques including the extrapolation from or interpolation between actively traded contracts, as well as the calculation of implied volatilities. When such inputs have a significant impact on the measurement of fair
value, the instrument is categorized as Level 3. The Company regularly evaluates and validates the inputs used to determine the fair value of Level 3 contracts by using pricing services to support the underlying market price of the
commodity.  F-138




---

The Company uses a discounted cash flow valuation technique to determine the fair value of
its derivative assets and liabilities. The primary inputs in the valuation models for commodity contracts are market observable forward commodity curves, risk-free discount rates, volatilities and, to a lesser degree, credit spreads. The primary
inputs into the valuation of interest rate swaps and foreign currency contracts are forward interest rates and foreign currency exchange rates and, to a lesser degree, credit spreads. Recurring Fair Value Measurements The following table summarizes the financial instruments measured at fair value on a recurring basis classified in the fair value hierarchy
(Level 1, 2 or 3) based on the inputs used for valuation in the consolidated balance sheets:  As of December 31, 2019

129,407 The Companys interest rate swaps, foreign currency contracts and financial commodity contracts are
considered Level 2, since all significant inputs are corroborated by market observable data. The Companys long-term physically settled commodity contracts (see Note 12. Derivatives) are considered Level 3 as they contain
significant unobservable inputs. There were no transfers in or out of Level 1, Level 2 and Level 3 during the years ended December 31, 2019 and 2018. The following table reconciles the changes in the fair value of derivative instruments classified as Level 3 in the fair value hierarchy

Increase (decrease) The Company measures the sensitivity of the fair value of its Level 3 commodity contracts to potential
changes in commodity prices using a mark-to-market analysis based on the current forward commodity prices and estimates of the price volatility. An increase in power
forward prices will produce a mark-to-market loss, while a decrease in prices will result in a
mark-to-market gain. An increase in the estimates of the price volatility will produce a
mark-to-market gain, while a decrease in volatility will result in a mark-to-market loss. Fair Value of Debt The
carrying amount and estimated fair value of the Companys long-term debt as of December 31, 2019 and 2018 was as follows:  As of December 31, 2019

$
5,789,702 The fair value of the Companys long-term debt, except the corporate-level senior notes, was determined
using inputs classified as Level 2 and a discounted cash flow approach using market rates for similar debt instruments. The fair value of the corporate-level senior notes is based on market price information which is classified as a
Level 1 input. They are measured using the last available trades at the end of each respective fiscal year. The fair values of the Senior Notes due 2023, Senior Notes due 2028 and Senior Notes due 2030 were 103.4%, 105.8% and 102.2% of face
value as of December 31, 2019, respectively. The fair values of the Senior Notes due 2023, Senior Notes due 2025 and Senior Notes due 2028 were 93.5%, 89.8% and 102.5% of face value as of December 31, 2018, respectively. Nonrecurring Fair Value Measurements Assets and liabilities that are measured at fair value on a nonrecurring basis relate primarily to renewable energy facilities, goodwill and
intangibles, which are remeasured when the derived fair value is below the carrying value on the Companys consolidated balance sheet. For these assets, the Company does not periodically adjust carrying value to fair value except in the event
of impairment. When the impairment has occurred, the Company measures the required charges and adjusts the carrying value as discussed in Note 2. Summary of Significant Accounting Policies. For discussion about the impairment testing of
assets and liabilities not measured at fair value on a recurring basis see Note 6. Renewable Energy Facilitiesand Note 7. Intangible Assets, Net and Goodwillfor additional details.  F-140

the Company is determined to be the primary beneficiary. VIEs are entities that lack one or more of the characteristics of a VOE. The Company has a controlling financial interest in a VIE when its variable interest(s) provide it with (i) the
power to direct the activities of the VIE that most significantly impact the VIEs economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant
to the VIE. The VIEs own and operate renewable energy facilities in order to generate contracted cash flows. The VIEs were funded through a combination of equity contributions from the owners and non-recourse
project-level debt.  F-141

STOCKHOLDERS EQUITY TerraForm Power, Inc. has 100,000,000 authorized shares of preferred stock of par value $0.01 per share, and 1,200,000,000 authorized shares of
Common Stock of par value $0.01 per share. There are no other authorized classes of shares and the Company does not have any issued shares of preferred stock. As of December 31, 2019, the combined ownership of affiliates of Brookfield was
approximately 62%. On January 11, 2020, the Company received an unsolicited, non-binding
proposal (the Brookfield Proposal) from Brookfield Renewable, an affiliate of Brookfield, to acquire all of the outstanding shares of Common Stock of the Company, other than the approximately 62% already held by Brookfield Renewable and
its affiliates. The Brookfield Proposal expressly conditioned the transaction contemplated thereby on the approval of a committee of the Board of Directors of the Company (the Board) consisting solely of independent Directors and the
approval of a majority of the shares held by the Companys stockholders not affiliated with Brookfield Renewable and its affiliates. Following the Companys receipt of the Brookfield Proposal, the Board formed a special committee (the
Special Committee) of non-executive, disinterested and independent Directors to, among other things, review, evaluate and consider the Brookfield Proposal and, if the Special Committee deemed
appropriate, negotiate a transaction with Brookfield Renewable or explore alternatives thereto. The Board resolutions  F-142




---

establishing the Special Committee expressly provided that the Board would not approve the transaction contemplated by the Brookfield Proposal or any alternative thereto without a prior favorable
recommendation by the Special Committee. On March 16, 2020, on the unanimous recommendation of the Special Committee and with the approval of the Board, the Company and Brookfield Renewable and certain of their affiliates entered into a
definitive agreement (the Reorganization Agreement) for Brookfield Renewable to, among other things, acquire all of the shares of Common Stock, other than the 62% currently owned by Brookfield Renewable and its affiliates (the
transactions contemplated by the Reorganization Agreement, the Transactions). Upon the consummation of the Transactions, each holder of a share of Common Stock that is issued and outstanding immediately prior to the consummation of the
Transactions, will be converted into the right to receive, at each TerraForm Power shareholders election, 0.381 of a Brookfield Renewable limited partnership unit or a Class A exchangeable subordinate voting share of Brookfield Renewable
Corporation, a Canadian subsidiary of Brookfield Renewable which is expected to be publicly listed as of the consummation of the Transactions. As provided by the Brookfield Proposal, the adoption of the Plan of Merger (as defined in the
Reorganization Agreement) and the approval of the Reorganization Agreement and the consummation of the transactions contemplated thereby is subject to the non-waivable approval of TerraForm Powers
shareholders representing a majority of the outstanding shares of Common Stock not owned by Brookfield Renewable and its affiliates and the consummation of the transactions contemplated by the Reorganization Agreement are subject to customary
closing conditions, including receipt of certain regulatory approval. As of the date of this Annual Report, Brookfield Renewable holds an approximately 30% indirect economic interest in TerraForm Power.

On October 8, 2019, the Company completed an underwritten registered public offering of 14,907,573 shares
of Common Stock at a price of $16.77 per share for a total consideration of $250.0 million, not including transaction costs. (2)
On October 8, 2019, concurrently with the public offering described above, the Company completed a private
placement of 2,981,514 shares of Common Stock at a price of $16.77 per share to an affiliate of Brookfield for a total consideration of $50.0 million, not including transaction costs. (3)
On June 11, 2018, the Company completed a private placement of 60,975,609 shares of the Companys
Common Stock with affiliates of Brookfield at a price of $10.66 per share for a total consideration of $650.0 million. The proceeds of the offering were used to pay a portion of the purchase price of the Tendered Shares of Saeta. On
August 3, 2018, the Company issued 80,084 shares of Common Stock to an affiliate of Brookfield in connection with the net losses incurred, such as out-of-pocket
losses, damages, costs, fees and expenses, in connection with the obtainment of a final resolution of a certain litigation matter. (4)
During the fourth quarter of 2019, the Company repurchased a total of 543,265 shares of Common Stock at a total
cost of $8.4 million and recorded within Treasury Stock on the consolidated balance sheets. Merger Consummation and
SunEdison Settlement Agreement As discussed in Note 1. Nature of Operations and Organization, on October 16, 2017,
pursuant to the Merger Agreement, Merger Sub merged with and into TerraForm Power, with TerraForm Power continuing as the surviving corporation in the Merger. Immediately following the consummation of the Merger, there were 148,086,027 Class A
shares of TerraForm Power outstanding, which excludes 138,402 Class A shares that were issued and held in treasury to pay applicable employee tax withholdings for RSUs held by employees that vested upon the consummation of the Merger. As a
result of the Merger, Orion Holdings acquired 51% of TerraForm Powers outstanding Class A shares. Prior to the consummation of
the Merger, SunEdison was the indirect holder of 100% of the shares of Class B common stock of TerraForm Power and held approximately 83.9% of the combined total voting power of the holders of TerraForm Powers Class A Common Stock
and Class B common stock. As contemplated by the Merger Agreement and in satisfaction of its obligations under the Settlement Agreement, SunEdison exchanged, effective immediately prior to the effective time of the Merger, all of the
Class B units of Terra LLC held by it or any of its controlled affiliates for 48,202,310 Class A shares of TerraForm Power. Following completion of this exchange, all of the issued and outstanding shares of Class B common stock
of TerraForm Power were automatically redeemed and retired. Pursuant to the Settlement Agreement,  F-143




---

immediately following this exchange, the Company issued to SunEdison additional Class A shares such that immediately prior to the effective time of the Merger, SunEdison and certain of
its affiliates held an aggregate number of Class A shares equal to 36.9% of TerraForm Powers fully diluted share count (which was subject to proration based on the Merger consideration election results as discussed below). As a result of
the Merger closing, TerraForm Power is no longer a controlled affiliate of SunEdison and is now a controlled affiliate of Brookfield. At
the effective time of the Merger, each share of Common Stock of TerraForm Power issued and outstanding immediately prior to the effective time of the Merger, except for certain excluded shares, was converted into the right to, at the holders
election and subject to proration as described below, either (i) receive $9.52 per Class A Share, in cash, without interest (the Per Share Cash Consideration) or (ii) retain one share of Common Stock, par value $0.01 per
share, of the surviving corporation (the Per Share Stock Consideration, and, together with the Per Share Cash Consideration, without duplication, the Per Share Merger Consideration). Issued and outstanding shares
included shares issued in connection with the SunEdison Settlement Agreement as more fully described above and shares underlying outstanding RSUs of the Company under the Companys 2014 Second Amended and Restated Long-Term Incentive Plan (the
2014 LTIP). At the effective time of the Merger, any vesting conditions applicable to any Company RSU outstanding immediately prior to the effective time of the Merger under the 2014 LTIP were automatically and without any required
action on the part of the holder, deemed to be satisfied in full, and such Company RSU was canceled and converted into the right to receive the Per Share Merger Consideration, including the election of the Per Share Stock Consideration or the Per
Share Cash Consideration in respect of each share (in the case of RSUs subject to performance conditions, with such conditions deemed satisfied at target levels), less any tax withholdings. The Per Share Stock Consideration was subject
to proration in the event that the aggregate number of Class A Shares for which an election to receive the Per Share Stock Consideration exceeded 49% of the TerraForm Power fully diluted share count (the Maximum Stock Consideration
Shares). Additionally, the Per Share Cash Consideration was subject to proration in the event that the aggregate number of Class A shares for which an election to receive the Per Share Cash Consideration exceeded the TerraForm Power fully
diluted share count minus (i) the Maximum Stock Consideration Shares, (ii) any Class A shares currently held by affiliates of Brookfield, and (iii) any shares for which the holders seek appraisal under Delaware law. Based on the
results of the consideration election, the elections of the Per Share Stock Consideration were oversubscribed and the proration ratio was 62.6%, which meant that stockholders electing to receive 100% of their merger consideration in stock retained
62.6% of their Class A shares in the Merger and received cash consideration in respect of 37.4% of their shares. On October 16,
2017, in connection with the consummation of the Merger, the Company entered into a registration rights agreement (the SunEdison Registration Rights Agreement) with SunEdison, SunEdison Holdings Corporation (SHC) and SUNE ML
1, LLC (SML1). The SunEdison Registration Rights Agreement governed the rights of SunEdison, SHC, SML1 and certain permitted assigns with respect to the registration for resale of Class A shares held by them immediately following
the Merger. The Company registered these shares in December of 2017, and these shares were distributed by SunEdison, Inc., SHC and SML1 to certain creditors under the plan of reorganization in connection with SunEdisons emergence from
bankruptcy in December of 2017. Upon the consummation of the Merger, TerraForm Powers certificate of incorporation was amended and
restated to include 100,000,000 authorized shares of preferred stock, par value $0.01 per share, and 1,200,000,000 authorized shares of Common Stock, par value $0.01 per share. There were no other authorized classes of shares, and the Company did
not have any issued shares of preferred stock as of December 31, 2019, 2018 and 2017. 2019 Public Offering and Concurrent Private Placement of
Common Stock to an Affiliate On October 8, 2019, the Company completed an underwritten registered public offering of
14,907,573 shares of Common Stock at a price of $16.77 per share (the Public Offering), for a total consideration of $250.0 million, not including transaction costs. In connection with the Public Offering, the Company entered into
an underwriting agreement, dated October 3, 2019 among the Company, Terra LLC and RBC Capital Markets, LLC, as the underwriter. Concurrent with the Public Offering, on October 8, 2019, the Company completed a private placement of 2,981,514 shares of Common Stock at
a price of $16.77 per share (the 2019 Private Placement), to BBHC Orion Holdco L.P., an affiliate of Brookfield (the 2019 Private Placement Purchaser), for a total consideration of $50.0 million, not including
transaction costs. No underwriting discounts or commissions were paid with respect to the 2019 Private Placement. In connection with the 2019 Private Placement, the Company entered into a stock purchase agreement, dated October 8, 2019, with
the 2019 Private Placement Purchaser. The Common Stock issued in the 2019 Private Placement were not registered with the SEC, in reliance on Section 4(a)(2) of the Securities Act and the acknowledgment of the 2018 Private Placement Purchaser
that it is an accredited investor within the meaning of Rule 501(a) of Regulation D of the Securities Act or a qualified institutional buyer under Rule 144A of the Securities Act. Following the Public Offering and the 2019
Private Placement, as of December 31, 2019, affiliates of Brookfield held approximately 62% of the Companys Common Stock.  F-144




---

The proceeds of the Public Offering and 2019 Private Placement were used to repay the
amounts due under the Revolver and for general corporate purposes. 2018 Private Placement of Common Stock to Affiliates On June 11, 2018, the Company completed a private placement of 60,975,609 shares of Common Stock at a price of $10.66 per share
(the 2018 Private Placement), to Orion Holdings and BBHC Orion Holdco L.P. (together, the 2018 Private Placement Purchasers) for a total consideration of approximately $650.0 million, not including transaction
costs. No underwriting discounts or commissions were paid with respect to the 2018 Private Placement. In connection with the 2018 Private Placement, the Company entered into a stock purchase agreement, dated June 11, 2018, with the 2018 Private
Placement Purchasers. The Common Stock issued in the 2018 Private Placement were not registered with the SEC, in reliance on Section 4(a)(2) of the Securities Act and the acknowledgment of each of the 2018 Private Placement Purchasers that it
is an accredited investor within the meaning of Rule 501(a) of Regulation D of the Securities Act or a qualified institutional buyer under Rule 144A of the Securities Act. Immediately upon completion of the 2018 Private
Placement, affiliates of Brookfield held approximately 65% of TerraForm Powers Common Stock as of the date thereof. The
proceeds of the 2018 Private Placement were used by the Company to pay a portion of the purchase price of the Tendered Shares of Saeta. The purchase of $650 million of TerraForm Powers Common Stock by the 2018 Private Placement Purchasers
was made pursuant to a support agreement that the Company had entered into with Brookfield, dated February 6, 2018, and amended on May 28, 2018, at the previously agreed backstop price of $10.66 per share. 2018 Issuance of Common Stock upon Final Resolution of Chamblee Class Action On August 3, 2018, pursuant to the Merger Agreement, the Company issued 80,084 shares of Common Stock to Orion Holdings in
connection with the net losses incurred as a result of the final resolution of a securities class action under federal securities laws (the Chamblee Class Action). The net losses for the Chamblee Class Action include the
$1.1 million contributed by the Company to the settlement but do not include the $13.6 million contributed by the Companys insurers and certain attorneys fees that TerraForm Global reimbursed to the Company pursuant to the
insurance allocation arrangements entered into with the Company in 2017. Cash Distributions The following table presents the cash distributions declared and/or paid on Common Stock during the years ended December 31, 2019, 2018

Share Repurchase Program On July 25, 2019, the Board of the Company authorized the renewal of the Companys share repurchase program through August 4,
2020. Under the share repurchase program, the Company may repurchase up to 5% of the Companys Common Stock outstanding as of July 25, 2019. The timing and the amount of any repurchases of Common Stock will be determined by the
Companys management based on its evaluation of market conditions and other factors. Repurchases of Common Stock may be made under a Rule 10b5-1 plan, which would permit Common Stock to be repurchased
when the Company might otherwise be precluded from doing so under insider trading laws, open market purchases, privately-negotiated transactions, block purchases or otherwise in accordance with applicable federal securities laws, including Rule 10b-18 under the Exchange Act. The program may be suspended or discontinued at any time and does not obligate the Company to purchase any minimum number of stock. Any repurchased Common Stock will be held by the
Company as treasury shares. The Company expects to fund any repurchases from the available liquidity. During the fourth quarter of 2019,
the Company repurchased 543,265 shares at a total cost of $8.4 million and recorded within Treasury Stock on the consolidated balance sheets. No shares were repurchased by the Company during the year ended December 31, 2018. 17. STOCK-BASED COMPENSATION In March 2018, the Company implemented its 2018 Amended and Restated Long-Term Incentive Plan (the 2018 LTIP), which is an equity
incentive plan that provides for the award of incentive and nonqualified stock options, restricted stock awards (RSAs) and RSUs to employees and directors of the Company. The 2018 LTIP amended and restated the 2014 LTIP. During the years
ended December 31, 2017 and 2016, the 2014 LTIP extended to employees and directors who also provided services to the Companys affiliates, including SunEdison and TerraForm Global during the periods those companies were affiliates of the
Company. The 2018 LTIP only applies to employees and directors of the Company. The maximum contractual term of an award is ten years from the date of grant. As of December 31, 2019, an aggregate of 3,734,185 shares of Common Stock were
available for issuance under the 2018 LTIP. Upon exercise of stock options or the vesting of RSUs, the Company will issue shares that have been previously authorized to be issued. Historically, stock-based compensation costs related to equity awards in the Companys stock were allocated to the Company, SunEdison and
TerraForm Global based on the relative percentage of time that the personnel and directors spent providing services to the respective companies. As of January 1, 2017, the Company hired certain former employees of SunEdison who provided
dedicated services to the Company. The amount of stock-based compensation expense related to equity awards in the Companys stock which has been awarded to the Companys employees was $11.3 million for the years ended
December 31, 2017, and is reflected in the consolidated statements of operations within general and administrative expenses. The total amount of stock-based compensation cost related to equity awards in the Companys stock which has been
allocated to SunEdison and TerraForm Global was $3.4 million for the year ended December 31, 2017, and was recognized as a distribution to SunEdison within Net SunEdison investment on the consolidated statements of stockholders
equity with no impact to the Companys consolidated statements of operations. Similarly, stock-based compensation costs related to equity awards in the stock of SunEdison and TerraForm Global awarded to employees of the Company were allocated
to the Company. The amount of stock-based compensation expense related to equity awards in the stock of SunEdison and TerraForm Global that was allocated to the Company was $5.5 million for the year ended December 31, 2017, and is
reflected in the consolidated statements of operations within general and administrative expensesaffiliate and has been treated as an equity contribution from SunEdison within Net SunEdison investment on the consolidated statements of
stockholders equity. In July of 2017, the Bankruptcy Court approved SunEdisons plan of reorganization which provided that all unvested equity awards in the stock of SunEdison would be canceled. As a result, all previously unrecognized
compensation cost pertaining to unvested equity awards in the stock of SunEdison that were held by the Companys employees of $2.2 million was allocated to the Company, which is reflected within the stock-based compensation expense amount
for the year ended December 31, 2017. Restricted Stock Awards RSAs provide the holder with immediate voting rights, but are restricted in all other respects until vested. Upon a termination of employment
for any reason, any unvested shares of Common Stock held by the terminated participant will be forfeited. All unvested RSAs are paid and distributions. There were no unvested RSAs as of December 31, 2017 and 2018.  F-146

1 year The total fair value of RSUs that vested during the years ended December 31, 2019, and 2017, was
$0.3 million and $16.7 million, respectively. The weighted average fair value of RSUs on the date of grant during the same periods was $12.17 and $12.22, respectively. No RSUs vested during the year ended December 31, 2018 and the
weighted-average fair value on the date of the grant was $11.15 per share. The unrecognized compensation cost related to the RSUs as of December 31, 2019 and 2018, was $1.6 million and $0.9 million, respectively. The vesting schedule
of the RSUs awarded in 2019 and 2018 is three years and the Company recognizes the grant-date fair value as a compensation cost on a straight-line basis over the vesting period. As discussed in Note 1. Nature of Operations and Organization, on October 16, 2017, TerraForm Power consummated the
Merger with certain affiliates of Brookfield. Pursuant to the 2014 LTIP, the Merger resulted in a change of control causing all unvested equity awards issued under the plan to vest. As a result, the Company recognized a $7.0
million stock-based compensation charge in the fourth quarter of 2017, which is reflected in the consolidated statements of operations within general and administrative expenses. The Company also recognized a $1.0 million charge
related to allocated stock-based compensation costs for equity awards in the stock of TerraForm Global that vested upon the change of control of TerraForm Power. The charge is reflected in the consolidated statements of operations within general and
administrative expensesaffiliate. Time-based RSUs During the year ended December 31, 2017, the Company awarded 523,877 time-based RSUs to certain employees and executive officers of
SunEdison, TerraForm Global and the Company. The weighted average grant-date fair value of these time-based awards during the same periods was $6.4 million which was calculated based on the Companys closing stock price on the date of
the grant. The vesting schedule of the awarded RSUs ranged from six months to four years, and the Company was recognizing the grant-date fair value as compensation cost on a straight-line basis over the vesting period. These time-based RSUs vested
upon the consummation of the Merger. During the year ended December 31, 2019 and 2018, the Company did not award any time-based RSUs.  F-147

Stock Options As of December 31, 2019 and 2018, there were no outstanding stock options and no unrecognized compensation cost in relation to stock
options. 18. NON-CONTROLLING INTERESTS Non-controlling Interests Non-controlling interests represent the portion of net assets in consolidated entities that are not
owned by the Company in renewable energy facilities. On December 22, 2017, the U.S. government enacted comprehensive tax legislation
commonly referred to as the Tax Cuts and Jobs Act, which enacted major changes to the U.S. tax code, including a reduction in the U.S. federal corporate income tax rate from 35% to 21%, effective January 1, 2018. Since
the 21% rate enacted in December 2017 went into effect on January 1, 2018, the HLBV methodology utilized by the Company to determine the value of its non-controlling interests began to use the
new rate on that date. The HLBV method is a point in time estimate that utilizes inputs and assumptions in effect at each balance sheet date based on the liquidation provisions of the respective operating partnership agreements. For the year
ended December 31, 2018, $151.2 million of the decline in the non-controlling interests balance and a corresponding allocation of net loss attributable to
non-controlling interests was driven by this reduction in the tax rate used in the HLBV methodology used by the Company. In the calculation of the carrying values through HLBV, the Company allocated
significantly lower amounts to certain non-controlling interests (i.e., tax equity investors) in order to achieve their contracted after-tax rate of return as a result
of the reduction of the federal income tax rate from 35% to 21% as specified in the Tax Act. Redeemable Non-controlling Interests Non-controlling interests in
subsidiaries that are redeemable either at the option of the holder or at fixed and determinable prices at certain dates are classified as redeemable non-controlling interests in subsidiaries between
liabilities and stockholders equity in the consolidated balance sheets. The redeemable non-controlling interests in subsidiaries balance is determined using the hypothetical liquidation at book value
method for the VIE funds or allocation of share of income or losses in other subsidiaries subsequent to initial recognition; however, the non-controlling interests balance cannot be less than the estimated
redemption value. The following table presents the activity of the redeemable non-controlling interests balance
for the years ended December 31, 2019, 2018 and 2017:  (In thousands)

During the year ended December 31, 2017, the Company recorded $6.7 million adjustment to the value of
the Invenergy Wind redeemable non-controlling interest, representing the excess of the future redemption value over its carrying amount based on the SEC guidance in ASC 480-10-S99-3A. Historically, the Company was accreting the redemption value of the Invenergy Wind redeemable non-controlling
interest over the redemption period using the straight-line method and accretion adjustments were recorded against additional paid-in capital. As part of the Settlement Agreement, the Option Agreement between
Terra LLC and Sun Edison LLC with respect to Invenergy Winds remaining 9.9% interest in certain subsidiaries of the Company was rejected upon the consummation of the Merger with affiliates of Brookfield on October 16, 2017. As a result,
the Company is no longer obligated to perform on its Option Agreement, and as of October 16, 2017, the Invenergy Wind non-controlling interest amount of $131.8 million was no longer considered
redeemable and was reclassified to non-controlling interests as of such date. The redemption adjustments recorded in additional paid-in capital will remain in additional
paid-in capital. (2)
See discussion in Note 2. Summary of Significant Accounting Policiesregarding the Companys
adoption of ASU No. 2014-09 and ASU No. 2016-08 as of January 1, 2018. (3)
During the year-ended December 31, 2019, the Company purchased the tax equity investors interests in
certain distributed generation projects in the United States for a combined consideration of $3.9 million, which resulted in increasing the Companys ownership interest in the related projects to 100%. The difference between the
consideration paid and the carrying amounts of the non-controlling interests was recorded as an adjustment to additional paid-in capital within Purchase of (redeemable) non-controlling interests in the consolidated statement of stockholders equity. 19.

Represents the cumulative-effect adjustment of deferred taxes stranded in AOCI resulting from the early

Companys customers, vendors and regulatory agencies often require the Company to post letters of credit in order to guarantee performance under certain contracts and agreements. The Company is also required to post letters of credit to secure
obligations under various swap agreements and leases and may, from time to time, decide to post letters of credit in lieu of cash deposits in reserve accounts under certain financing arrangements. The amount that can be drawn under some of these
letters of credit may be increased from time to time subject to the satisfaction of certain conditions. As of December 31, 2019, the Company had outstanding letters of credit drawn under the Revolver of $115.5 million and outstanding
project-level letters of credit of $266.9 million, drawn under certain project-level financing agreements, respectively, compared to $99.5 million and $197.7 million as of December 31, 2018, respectively. Guaranty Agreements The Company
and its subsidiaries have entered into guaranty agreements to certain of their institutional tax equity investors and financing parties in connection with their tax equity financing transactions. These agreements do not guarantee the returns
targeted by the tax equity investors or financing parties, but rather support any potential indemnity payments payable under the tax equity agreements, including related to management of tax partnerships and recapture of tax credits or renewable
energy grants in connection with transfers of the Companys direct or indirect ownership interests in the tax partnerships to entities that are not qualified to receive those tax benefits. The Company and its subsidiaries have also provided guaranties in connection with acquisitions of third-party assets or to support
project-level contractual obligations, including renewable energy credit sales agreements. The Company and its subsidiaries have also provided other capped or limited contingent guaranties and other support obligations with respect to certain
project-level indebtedness. The amounts of the above guaranties often are not explicitly stated and the overall maximum amount of the
related obligations cannot be reasonably estimated. Historically, no significant payments have been made with respect to these types of guaranties. The Company believes the probability of payments being demanded under these guaranties is remote and
no material amounts have been recognized for the underlying fair value of guaranty obligations.  F-150

Operating Leases The Company has operating leases for renewable energy production facilities, land, office space, transmission lines, vehicles and other
operating equipment. See Note 8. Leasesfor details of the Companys lease arrangements, including rental expense, and future commitments under operating leases. Long-Term Service Agreements On
August 10, 2018, the Company executed an 11-year framework agreement with affiliates of General Electric (GE) that, among other things, provides for the roll out, subject to receipt of
third-party consents, of project level, long-term service agreements (LTSA) for turbine operations and maintenance O&M, as well as other balance of plant services across the Companys 1.6 GW North American wind
fleet. As of December 31, 2019, 15 of 16 project-level LTSAs were in place. Pursuant to the LTSAs with GE, if a facility generates less than the resource-adjusted amount of guaranteed generation, GE is liable to make a payment to the Company,
as liquidated damages, corresponding to the amount of operating revenues lost due to such shortfall, after taking into account certain exclusions. In addition, if a facility generates more than the resource-adjusted amount of guaranteed generation,
the Company has an obligation to pay a bonus to GE. On November 1, 2019, the Company executed a
10-year framework agreement with SMA Solar Technology that, among other things, provides for the roll out, subject to receipt of third-party consents, of project level LTSAs for solar O&M, as well as other
balance of plant services across the Companys North American solar fleet. Legal Proceedings The Company is not a party to any material legal proceedings other than various administrative and regulatory proceedings arising in the
ordinary course of the Companys business or as described below. While the Company cannot predict with certainty the ultimate resolution of such proceedings or other claims asserted against the Company, certain of the claims, if adversely
concluded, could result in substantial damages or other relief. Claim relating to First Wind Acquisition On May 27, 2016, D.E. Shaw Composite Holdings, L.L.C. and Madison Dearborn Capital Partners IV, L.P., as the representatives of the
sellers (the First Wind Sellers) filed an amended complaint for declaratory judgment against TerraForm Power and Terra LLC in the Supreme Court of the State of New York alleging breach of contract with respect to the Purchase and Sale
Agreement, dated as of November 17, 2014 (the FW Purchase Agreement) between, among others, SunEdison, Inc. (SunEdison), TerraForm Power, Terra LLC and the First Wind Sellers. The amended complaint alleges that Terra LLC
and SunEdison became jointly obligated to make $231.0 million in earn-out payments in respect of certain development assets SunEdison acquired from the First Wind Sellers under the FW Purchase Agreement,
when those payments were purportedly accelerated by SunEdisons bankruptcy and by the resignations of two SunEdison employees. The amended complaint further alleges that TerraForm Power, as guarantor of certain Terra LLC obligations under the
FW Purchase Agreement, is liable for this sum. In addition, the plaintiffs have claimed legal costs and expenses and, under applicable New York law, their claim accrues interest at a non-compounding rate of 9%
per annum. The defendants filed a motion to dismiss the amended complaint on July 5, 2016, on the ground that, among other things,
SunEdison is a necessary party to this action. On February 6, 2018, the court denied the Companys motion to dismiss after which document discovery began. In April 2019, Terra LLC filed an amended answer to the amended complaint. The
Company cannot predict the impact on this litigation of any information that may become available in discovery. Document discovery and depositions are now substantially completed and new pretrial schedule has been agreed between the parties and
approved by the court. Subsequent to year end, on January 24, 2020, the parties filed their respective motions to dismiss and on February 12, 2020, the parties filed their respective opposition briefs. The courts ruling on the
motions to dismiss is expected before the end of 2020. The Company believes the First Wind Sellers allegations are without merit
and will contest them vigorously. However, the Company cannot predict with certainty the ultimate resolution of any proceedings brought in connection with such a claim.  F-151

Whistleblower Complaint by Francisco Perez Gundin On May 18, 2016, the Companys former Director and Chief Operating Officer, Francisco Perez Gundin (Mr. Perez), filed a
complaint against the Company, TerraForm Global, Inc. (TerraForm Global) and certain individuals, with the United States Department of Labor. The complaint alleged that the defendants engaged in a retaliatory termination of Mr.
Perezs employment after he allegedly voiced concerns to SunEdisons Board of Directors about public representations made by SunEdison officers regarding SunEdisons liquidity position, and after he allegedly voiced his opposition to
transactions that he alleged were self-interested and which he alleged SunEdison forced on the Company. He alleged that the Company participated in SunEdisons retaliatory termination by constructively terminating his position as Chief
Operating Officer of the Company in connection with SunEdisons constructive termination of his employment. He sought lost wages, bonuses, benefits, and other money that he alleged he would have received if he had not been subjected to the
allegedly retaliatory termination. The Companys Position Statement in response to the complaint was filed in October 2016. On
February 21, 2017, Mr. Perez filed Gundin v. TerraForm Global, Inc. et al. against TerraForm Power, TerraForm Global and certain individuals as defendants in the United States District Court for the District of Maryland, which was
subsequently transferred to the U.S. District Court for the Southern District of New York (SDNY). The complaint asserted claims for retaliation, breach of the implied covenant of good faith and fair dealing and promissory estoppel based
on the same allegation in Mr. Perezs Department of Labor complaint. On March 8, 2018, Mr. Perez voluntarily dismissed the federal action without prejudice. On December 27, 2018, the proceeding before the Department of Labor
was dismissed, which Mr. Perez appealed on January 25, 2019. On August 27, 2019, pursuant to Mr. Perezs offer to settle the dispute, a definitive settlement agreement was executed between the Company and Mr. Perez. The
settlement with Mr. Perez was paid entirely from insurance proceeds. Whistleblower Complaint by Carlos Domenech Zornoza On May 10, 2016, the Companys former Director and Chief Executive Officer, Carlos Domenech Zornoza (Mr. Domenech),
filed a complaint against the Company, TerraForm Global and certain individuals, with the United States Department of Labor. The complaint alleges that the defendants engaged in a retaliatory termination of Mr. Domenechs employment on
November 20, 2015, after he allegedly voiced concerns to SunEdisons Board of Directors about public representations made by SunEdison officers regarding SunEdisons liquidity position, and after he allegedly voiced his opposition to
transactions that he alleges were self-interested and which he alleges SunEdison forced on the Company. He alleges that the Company participated in SunEdisons retaliatory termination by terminating his position as Chief Executive Officer of
the Company in connection with SunEdisons termination of his employment. He seeks lost wages, bonuses, benefits, and other money that he alleges that he would have received if he had not been subjected to the allegedly retaliatory termination.
The Companys Position Statement in response to the complaint was filed in October 2016. On February 21, 2017,
Mr. Domenech filed Domenech Zornoza v. TerraForm Global, Inc. et. al against TerraForm Power, TerraForm Global and certain individuals as defendants in the United States District Court for the District of Maryland. The complaint asserted claims
for retaliation, breach of the implied covenant of good faith and fair dealing and promissory estoppel based on the same allegations in Mr. Domenechs Department of Labor complaint. On March 15, 2017, the Company filed notice with the
Judicial Panel on Multidistrict Litigation to transfer this action to the SDNY where other cases not involving the Company relating to the SunEdison bankruptcy are being tried. The plaintiff opposed the transfer. However, the transfer was approved
by the Judicial Panel on Multidistrict Litigation. On November 6, 2017, TerraForm Power and the other defendants filed a motion to dismiss Mr. Domenechs complaint, and Mr. Domenech filed a response on December 21, 2017. On
March 8, 2018, Mr. Domenech voluntarily dismissed the federal action without prejudice, which would permit the action to be refiled. On August 16, 2018, Mr. Domenech filed a second complaint with the United States District Court for the District of Maryland, with
substantially the same allegations. On October 17, 2018, the Company filed notice with the Judicial Panel on Multidistrict Litigation to transfer this action to the SDNY. The Plaintiff opposed the transfer. However, the transfer was approved by
the Judicial Panel on Multidistrict Litigation. On March 15, 2019, the Company, TerraForm Global, and several individual defendants filed a joint motion to dismiss Mr. Domenechs complaint. Mr. Domenech filed a response on
April 15, 2019, and the Company, TerraForm Global, and the individual defendants filed a reply on April 25, 2019. On December 9, 2019, the Court dismissed two of his three claims against the Company and TerraForm Global. On
January 22, 2020, the Company filed an answer to Mr. Domenechs remaining, narrowed claim of retaliatory termination. The
Company reserved for its estimated loss related to this complaint in 2016, which was not considered material to the Companys consolidated results of operations, and this amount remains accrued as of December 31, 2019. However, the Company
is unable to predict with certainty the ultimate resolution of these proceedings. Derivative Class Action On September 19, 2019, lead plaintiff Martin Rosson filed a derivative and class action lawsuit in the Delaware Court of Chancery on
behalf of the Company, himself, and other minority stockholders of the Company against Brookfield and certain of its affiliates (including the Company as a nominal defendant). The complaint alleges that the defendant controlling stockholders
breached their fiduciary duty to minority stockholders because the Company undertook a private placement of the Companys stock on terms that the complaint alleges are unfair, instead of pursuing a public offering. The proceeds of the  F-152




---

private placement were used to fund the acquisition by the Company of Saeta and had been approved by the Conflicts Committee of the Companys Board of Directors. The complaint seeks the
rescission and invalidation of the private placement and payment to the Company of rescissory damages, among other relief. In a related development, on October 15, 2019, the Company received a demand letter for the production of books and
records pursuant to 8 Del. C. § 220 to allow counsel to the City of Dearborn Policy and Retirement System (a purported shareholder of the Company) to investigate potential breaches of fiduciary duty by Brookfield and the Companys Board of
Directors in connection with the funding of the acquisition of Saeta. Subsequent to year end, on January 27, 2020, the City of Dearborn Police and Retirement System filed a derivative and class action lawsuit in the Delaware Court of Chancery on
behalf of the Company, itself, and other minority stockholders of the Company against Brookfield and certain of its affiliates (including the Company as a nominal defendant) alleging claims similar to those set forth in the Rosson complaint. The
City of Dearborn Police and Retirement System and Martin Rosson agreed, with the consent of the Company and Brookfield, to consolidate their respective claims and such consolidation was approved by the Court during the first quarter of 2020. While
the Company believes that these claims are without merit, it cannot predict with certainty the ultimate resolution of any proceedings brought in connection with these claims. Chile Project Arbitration On
September 5, 2016, Compañía Minera del Pacífico (CMP) submitted demands for arbitration against the subsidiary of the Company that owns its solar project located in Chile and against the latters immediate
holding company to the Santiago Chamber of Commerces Center for Arbitration and Mediation (CAM). The demands alleged, among other things, that the Chile project was not built, operated and maintained according to the relevant
standards using prudent utility practices as required by the electricity supply agreement (the Contract for Difference) between the parties, entitling them to terminate the Contract for Difference. CMP further alleged that it is entitled
to damages based on alleged breaches of a call option agreement entered into by the parties. In June 2019, the CAM issued two rulings in
which it unanimously rejected the claims made by CMP. CMP indicated that they would not seek to appeal the ruling and the window in which they are permitted to appeal the ruling has now closed. Other matters Two of the Companys
project level subsidiaries are parties to litigation that is seeking to recover alleged underpayments of tax grants under Section 1603 of the American Recovery and Reinvestment Tax Act from the U.S. Department of Treasury (U.S.
Treasury). These project level subsidiaries filed complaints at the Court of Federal Claims on March 28, 2014. The U.S. Treasury counterclaimed and both claims went to trial in July 2018. In January 2019, the Court of Federal Claims
entered judgments against each of the project level subsidiaries for approximately $10.0 million in the aggregate. These judgments are being appealed. The project level subsidiaries expect that losses, if any, arising from these claims would be
covered pursuant to an indemnity and, accordingly, the Company recognized a corresponding indemnification asset within other current assets in the consolidated balance sheets as of December 31, 2019 and December 31, 2018. Issuance of Shares upon Final Resolution of Certain Litigation Matters Pursuant to the definitive merger and sponsorship agreement (the Merger Agreement) entered into with Orion Holdings on
March 6, 2017, the Company has agreed to issue additional shares of Common Stock to Orion Holdings for no additional consideration in respect of the Companys net losses, such as out-of-pocket losses, damages, costs, fees and expenses, in connection with the obtainment of a final resolution of certain specified litigation matters (including the litigation brought by the First Wind
Sellers, Mr. Perez and Mr. Domenech described above) within a prescribed period following the final resolution of such matters. The number of additional shares of Common Stock to be issued to Orion Holdings is subject to a pre-determined formula as set forth in the Merger Agreement and is described in greater detail in the Companys Definitive Proxy Statement on Schedule 14A filed with the SEC on September 6, 2017. The
issuance of additional shares to Orion Holdings would dilute the holdings of the Companys common stockholders and may negatively affect the value of the Companys Common Stock. The settlement with Mr. Perez was paid entirely from insurance proceeds and no shares have been issued to Brookfield in connection with
the settlement. As of the date hereof, the Company is unable to predict the quantum of any net losses arising from any of the litigation brought by the First Wind Sellers or Mr. Domenech described above or the number of additional shares, if
any, that may be required to be issued to Orion Holdings pursuant to the terms of the Merger Agreement in connection with any final resolution of such matters.  F-153

21. RELATED PARTIES As discussed inNote 1. Nature of Operations and Organization, the Company is a controlled affiliate of Brookfield.
Brookfield held approximately 62% of the voting securities of TerraForm Powers Common Stock as of December 31, 2019. Certain affiliates of Brookfield hold the outstanding IDRs of Terra LLC held by certain affiliates of
Brookfield, and the Company and the Brookfield IDR Holder entered into an amended and restated limited liability company agreement of Terra LLC as discussed below under Brookfield Sponsorship Transaction, which adjusted the distribution
thresholds and percentages applicable to the IDRs. Brookfield Non-Binding Proposal and Signing of Reorganization Agreement On January 11, 2020, the Company received an unsolicited and non-binding proposal from Brookfield
Renewable Partners L.P., an affiliate of Brookfield, to acquire all of the outstanding shares of Common Stock of the Company, other than the approximately 62% shares held by Brookfield Renewable and its affiliates. The Brookfield Proposal expressly
conditioned the transaction contemplated thereby on the approval of a committee of the Board consisting solely of independent directors and the approval of a majority of the shares held by the Companys stockholders not affiliated with
Brookfield Renewable and its affiliates. Following the Companys receipt of the Brookfield Proposal, the Board formed a Special Committee of non-executive, disinterested and independent directors to,
among other things, review, evaluate and consider the Brookfield Proposal and, if the Special Committee deemed appropriate, negotiate a transaction with Brookfield Renewable or explore alternatives thereto. The Board resolutions establishing the
Special Committee expressly provided that the Board would not approve the transaction contemplated by the Brookfield Proposal or any alternative thereto without a prior favorable recommendation by the Special Committee. Brookfield Renewable holds an
approximately 30% indirect economic interest in TerraForm Power. On March 16, 2020, pursuant to the Brookfield Proposal, the Company
and Brookfield Renewable and certain of their affiliates entered into the Reorganization Agreement for Brookfield Renewable to acquire all of the Companys outstanding shares of Common Stock, other than the approximately 62% currently owned by
Brookfield Renewable and its affiliates. Pursuant to the Reorganization Agreement, each holder of a share of Common Stock that is issued and outstanding immediately prior to the consummation of the Transactions will receive, at each such
shareholders election, 0.381 of a Brookfield Renewable limited partnership unit or of a Class A exchangeable subordinate voting share of Brookfield Renewable Corporation, a Canadian subsidiary of Brookfield Renewable which is expected to
be publicly listed as of the consummation of the Transactions. The Special Committee has unanimously recommended that the Companys unaffiliated shareholders approve the Transactions. Consummation of the Transactions is subject to the non-waivable approval of a majority of the Companys shareholders not affiliated with Brookfield Renewable, receipt of required regulatory approvals and other customary closing conditions. Brookfield Sponsorship Transaction As discussed in Note 1. Nature of Operations and Organization, the Company entered into a suite of agreements with Brookfield and/or
certain of its affiliates providing for sponsorship arrangements, as are more fully described below. Brookfield Master Services Agreement The Company entered into a master services agreement (the Brookfield MSA) with Brookfield and certain affiliates of
Brookfield (collectively, the MSA Providers) pursuant to which the MSA Providers provide certain management and administrative services to the Company, including the provision of strategic and investment management services. As
consideration for the services provided or arranged for by Brookfield and certain of its affiliates pursuant to the Brookfield MSA, the Company pays a base management fee on a quarterly basis that is paid in arrears and calculated as follows:  

for each of the first four quarters following the closing date of the Merger, a fixed component of
$2.5 million per quarter (subject to proration for the quarter including the closing date of the Merger) plus 0.3125% of the market capitalization value increase for such quarter;  

for each of the next four quarters, a fixed component of $3.0 million per quarter adjusted annually for
inflation plus 0.3125% of the market capitalization value increase for such quarter; and  

thereafter, a fixed component of $3.75 million per quarter adjusted annually for inflation plus 0.3125% of
the market capitalization value increase for such quarter. For purposes of calculating the quarterly payment of the
base management fee, the term market capitalization value increase means, for any quarter, the increase in value of the Companys market capitalization for such quarter, calculated by multiplying the number of outstanding shares of common stock
as of the last trading day of such quarter by the difference  F-154




---

between (x) the volume-weighted average trading price of a share of common stock for the trading days in such quarter and (y) $9.52. If the difference between (x) and (y) in the market
capitalization value increase calculation for a quarter is a negative number, then the market capitalization value increase is deemed to be zero. Pursuant to the Brookfield MSA, the Company recorded charges of $26.8 million and $14.6 million within General and administrative
expensesaffiliate in the consolidated statements of operations for the year ended December 31, 2019 and 2018, respectively. The balance payable under the Brookfield MSA was $8.6 million and $4.2 million in the consolidated
balance sheets as of December 31, 2019 and 2018, respectively. Relationship Agreement The Company entered into a relationship agreement (the Relationship Agreement) with Brookfield, which governs certain aspects of
the relationship between Brookfield and the Company. Pursuant to the Relationship Agreement, Brookfield agrees that the Company will serve as the primary vehicle through which Brookfield and certain of its affiliates will own operating wind and
solar assets in North America and Western Europe and that Brookfield will provide the Company, subject to certain terms and conditions, with a right of first offer on certain operating wind and solar assets that are located in such countries and
developed by persons sponsored by or under the control of Brookfield. The rights of the Company under the Relationship Agreement are subject to certain exceptions and consent rights set out therein. See Item 1A. Risk Factors. Risks Related
to our Relationship with Brookfield. The Company did not acquire any renewable energy facilities from Brookfield during the years ended December 31, 2019 and 2018. Terra LLC Agreement BRE Delaware,
Inc. (the Brookfield IDR Holder), an indirect, wholly-owned subsidiary of Brookfield, holds all of the outstanding IDRs of Terra LLC. The Company, Brookfield IDR Holder and TerraForm Power Holdings, Inc. are party to the limited
liability company agreement of Terra LLC (as amended from time to time, the Terra LLC Agreement). Under the Terra LLC Agreement, IDRs are payable when distributions on Common Stock reach a certain threshold. The IDR threshold for a first
distribution is $0.93 per share of Common Stock and for a second distribution is $1.05 per share of Common Stock. There were no IDR payments made by the Company pursuant to the Terra LLC Agreement during the years ended December 31, 2019 and
2018. Registration Rights Agreement The Company entered into a registration rights agreement (the Registration Rights Agreement) on October 16, 2017 with Orion
Holdings. On June 11, 2018, Orion Holdings, Brookfield BRP Holdings (Canada) Inc. and the Company entered into a Joinder Agreement pursuant to which Brookfield BRP Holdings (Canada) Inc. became a party to the Registration Rights Agreement. On
June 29, 2018, a second Joinder Agreement was entered into among Orion Holdings, Brookfield BRP Holdings (Canada) Inc., BBHC Orion Holdco L.P. and the Company pursuant to which BBHC Orion Holdco L.P. became a party to the Registration Rights
Agreement. The Registration Rights Agreement governs the rights and obligations of the parties thereto with respect to the registration for resale of all or a part of the Class A shares held by Orion Holdings, BBHC Orion Holdco L.P and such
other affiliates of Brookfield from time to time to the Registrations Rights Agreement. Sponsor Line Agreement On October 16, 2017, the Company entered into the Sponsor Line with Brookfield and one of its affiliates (the Lenders). The
Sponsor Line establishes a $500.0 million secured revolving credit facility and provides for the Lenders to commit making LIBOR loans to the Company during a period not to exceed three years from the effective date of the Sponsor Line (subject
to acceleration for certain specified events). The Company may only use the revolving Sponsor Line to fund all or a portion of certain funded acquisitions or growth capital expenditures. The Sponsor Line terminates, and all obligations
thereunder become payable, no later than October 16, 2022. Borrowings under the Sponsor Line bear interest at a rate per annum equal to a LIBOR rate determined by reference to the costs of funds for U.S. dollar deposits for the interest period
relevant to such borrowing adjusted for certain additional costs, in each case plus 3.00% per annum. In addition to paying interest on outstanding principal under the Sponsor Line, the Company is required to pay a standby fee of 0.50% per annum
in respect of the unutilized commitments thereunder, payable quarterly in arrears. As a consideration for entering into the Sponsor Line credit facility, the Company paid Brookfield an upfront fee of $5.0 million representing 1.00% of the
credit facility amount during the year ended December 31, 2017, which is recorded, less the cumulative amortization expense, within other assets in the consolidated balance sheets. The Company is permitted to voluntarily reduce the unutilized
portion of the commitment amount and repay outstanding loans under the Sponsor Line at any time without premium or penalty, other than customary breakage costs. TerraForm Powers obligations under the Sponsor Line are secured by
first-priority security interests in substantially all assets of TerraForm Power, including 100% of the capital stock of Terra LLC, in each case subject to certain exclusions set forth in the credit documentation governing the Sponsor Line. Under
certain circumstances, the  F-155




---

Company may be required to prepay amounts outstanding under the Sponsor Line. During the year ended December 31, 2018, the Company made two draws on the Sponsor Line totaling
$86.0 million that were used to fund part of the purchase price of the acquisition of Saeta and repaid such amounts in full. As of December 31, 2019, and December 31, 2018, respectively, there were no amounts drawn under the Sponsor
Line. Total interest expense, including the amortization of the deferred financing costs incurred on the Sponsor Line for the years ended December 31, 2019, 2018, and 2017, amounted to $4.2 million, $5.2 million, and
$0.9 million, respectively. Governance Agreement In connection with the consummation of the Merger, the Company entered into a governance agreement (the Governance Agreement) with
Orion Holdings and any controlled affiliate of Brookfield (other than the Company and its controlled affiliates) that by the terms of the Governance Agreement from time to time becomes a party thereto. The Governance Agreement establishes certain
rights and obligations of the Company and controlled affiliates of Brookfield that own voting securities of the Company relating to the governance of the Company and the relationship between such affiliates of Brookfield and the Company and its
controlled affiliates. On June 11, 2018, Orion Holdings, Brookfield BRP Holdings (Canada) Inc. and the Company entered into a Joinder Agreement pursuant to which Brookfield BRP Holdings (Canada) Inc. became a party to the Governance Agreement.
On June 29, 2018, a second Joinder Agreement was entered into among Orion Holdings, Brookfield BRP Holdings (Canada) Inc., BBHC Orion Holdco L.P. and the Company pursuant to which BBHC Orion Holdco L.P. became a party to the Governance
Agreement. New York Office Lease & Co-tenancy Agreement In May 2018 and in connection with the relocation of the Companys corporate headquarters to New York City, the Company entered into a
lease for office space and related co-tenancy agreement with affiliates of Brookfield for a ten-year term. The Company recorded $0.9 million and $0.8 million
of charges within general and administrative expensesaffiliate in the consolidated statements of operations during the years ended December 31, 2019 and 2018, respectively. Amended and Restated Terra LLC Agreement As discussed above, SunEdison transferred all of the outstanding IDRs of Terra LLC held by SunEdison or certain of its affiliates to Brookfield
IDR Holder at the effective time of the Merger, and the Company and Brookfield IDR Holder entered into an amended and restated limited liability company agreement of Terra LLC (as amended from time to time, the New Terra LLC Agreement).
The New Terra LLC Agreement, among other things, reset the IDR thresholds of Terra LLC to establish a first distribution threshold of $0.93 per share of Common Stock and a second distribution threshold of $1.05 per share of Common Stock. As a result
of the New Terra LLC Agreement, amounts distributed from Terra LLC are distributed on a quarterly basis as follows:  

first, to the Company in an amount equal to the Companys outlays and expenses for such quarter;  

second, to holders of Class A units, until an amount has been distributed to such holders of Class A
units that would result, after taking account of all taxes payable by the Company in respect of the taxable income attributable to such distribution, in a distribution to holders of shares of Common Stock of $0.93 per share (subject to adjustment
for distributions, combinations or subdivisions of shares of Common Stock) if such amount were distributed to all holders of shares of Common Stock;  

third, 15% to the holders of the IDRs and 85% to the holders of Class A units until a further amount has
been distributed to holders of Class A units in such quarter that would result, after taking account of all taxes payable by the Company in respect of the taxable income attributable to such distribution, in a distribution to holders of shares
of Common Stock of an additional $0.12 per share (subject to adjustment for distributions, combinations or subdivisions of shares of Common Stock) if such amount were distributed to all holders of shares of Common Stock; and  

thereafter, 75% to holders of Class A units and 25% to holders of the IDRs. The Company made no IDR payments during the years ended December 31, 2019 and 2018. Other Brookfield Transactions and Agreements 2018 Private Placement As discussed in

the Company completed the 2019 Private Placement, whereby affiliates of Brookfield purchased 2,981,514 shares of Common Stock at a price per share of $16.77, representing total consideration of $50.0 million. Upon completion of the Public
Offering and the 2019 Private Placement, as of December 31, 2019, affiliates of Brookfield held approximately 62% of TerraForm Powers Common Stock. 1 Acquisition-related Services During
the year ended December 31, 2019, an affiliate of Brookfield incurred $1.4 million for services and fees payable on behalf of the Company in relation to acquisitions in Spain. These costs primarily represent professional fees for legal,
valuation and accounting services. In connection with bank guarantees issued in support of the Saeta acquisition (Note 3. Acquisitions
and Divestitures), Brookfield provided credit support to the Company, and the Company agreed to pay a fee to Brookfield equal to 50% of the savings realized by the Company as a result of Brookfields provision of credit support, which
amounted to $2.9 million and was paid in the second quarter of 2018. The bank guarantees were canceled following the acquisition of Saeta and no amounts remain outstanding thereunder. During the year ended December 31, 2018, the Company paid an affiliate of Brookfield $4.0 million for services and fees paid on
behalf of the Company by affiliates of Brookfield in relation to the acquisition of Saeta. These costs primarily represent investment banker advisory fees and professional fees for legal and accounting services. Recovery of Short-swing Profit Claim During the year ended December 31, 2018, the Company received $3.7 million from Brookfield and certain of its affiliates for the
settlement of claims relating to certain transactions under Section 16 (b) of the Exchange Act. The Company recognized the net proceeds of $3.0 million as a capital contribution from a stockholder and recorded it as an increase to
additional paid-in capital, which is reflected within the other line in the consolidated statements of stockholders equity for the year ended December 31, 2018. Commodity Contracts During the year
December 31, 2018, the Company entered into agreements with an affiliate of Brookfield regarding the financial swap of certain commodity contracts. These agreements were entered on a flow-through, cost-reimbursement basis, and did not result in
any fees or other amounts payable by the Company to any Brookfield affiliate. During the years ended December 31, 2019 and 2018, a total of $0.5 million and $1.2 million, respectively, was recorded pursuant to these agreements on a
cost-reimbursement basis by the Company to the Brookfield counterparty. Chamblee Class Action Settlement As discussed inNote16.Stockholders Equity, on August 3, 2018, pursuant to
the Merger Agreement, the Company issued 80,084 shares of Common Stock to Orion Holdings in connection with the net losses incurred as a result of the final resolution of the Chamblee Class Action. Due from affiliates The $0.5
million and $0.2 million due from affiliates amount reported on the consolidated balance sheets as of December 31, 2019 and 2018, respectively, represents a receivable from certain affiliates of Brookfield, as a result of
payments made by the Company on their behalf, primarily related to professional fees and rent for shared corporate headquarters, compensation for certain employees that provided services to both companies and certain information technology services.
There was no right of set-off with respect to these receivables from affiliates and the payables to the other Brookfield affiliates described herein, and thus these amounts were separately reported in due from
affiliate in the consolidated balance sheets.  F-157




---

Due to affiliates The $11.5 million due to affiliates amount reported on the consolidated balance sheets as of December 31, 2019, represented (i)

acquisitions in Spain, (iii) $0.6 million standby fee payable under the Sponsor Line, (iv) $0.5 million payable for commodity contracts executed on behalf of the Company on a cost-reimbursement basis, and (v) $0.4 million payables
related to rent, office charges and other services to affiliates of Brookfield related to the Company corporate headquarters in New York. The $7.0 million due to affiliates amount reported in the consolidated balance sheets as of December 31, 2018, primarily represented
payables to affiliates of Brookfield of $4.2 million for the Brookfield MSA quarterly base management fee for the fourth quarter of 2018 and $2.8 million for leasehold improvements, rent, office charges and other services associated with
the transition to the Companys new corporate headquarters during 2018. During the year ended December 31, 2019, the Company
paid affiliates of Brookfield $22.4 million for the Brookfield MSA base management fee, $1.9 million representing standby fee interest payable under the Sponsor Line, and $3.6 million for leasehold improvements, rent, office charges

paid in the second quarter of 2018. Agreements with X-Elio Energy As discussed in Note 3. Acquisitions and Divestitures, on December 18, 2019, the Company acquired an approximately 45
MW portfolio of utility-scale solar photovoltaic power plants in Spain from subsidiaries of X-Elio Energy, S.L. (X-Elio). Contemporaneously with the closing
of the X-Elio Acquisition, Brookfield and certain of its institutional partners entered into a 50-50 joint venture in respect of
X-Elio. The X-Elio Acquisition was pursuant to three
share purchase agreements with X-Elio (collectively the X-Elio SPAs), pursuant to which the Company acquired three
X-Elio subsidiaries. In connection with the X-Elio Acquisition, on the closing date, the Company entered into a Transitional Services Agreement (the X-Elio TSA) with X-Elio. The X-Elio TSA provides for X-Elio to support the Company
on a transitional basis by providing certain accounting and other services for an initial three-month term that may be extended at the election of the Company for an additional three-month term. In addition, the subsidiaries acquired by the Company
on the closing date were party to existing O&M agreements with X-Elio (collectively, the X-Elio O&M Agreements), pursuant to which X-Elio provided O&M services to the acquired solar power facilities. Under the terms of the X-Elio SPAs, the X-Elio O&M
Agreements will remain in effect for a maximum 12-month term after the closing date, subject to earlier termination at the Companys election, for a total consideration of 1.0 million per annum
(equivalent to $1.1 million as of December 31, 2019). Under the X-Elio SPAs, certain indemnity and other obligations remain in place post-closing of the acquisition but no post-closing payments are
expected to be made by either party in the ordinary course. SunEdison Matters SunEdison Bankruptcy and Settlement Agreement with SunEdison As discussed in Note 1. Nature of Operations and Organization, TerraForm Power entered into the Settlement Agreement with
SunEdison on March 6, 2017, which was approved by the Bankruptcy Court. The settlements, mutual intercompany releases, and certain other terms and conditions became effective upon the consummation of the Merger with affiliates of Brookfield on
October 16, 2017. The effectiveness of these Settlement Agreement provisions has resolved claims between TerraForm Power and SunEdison, including, among other things, claims of SunEdison against the Company for alleged fraudulent and
preferential transfers and claims of the Company against SunEdison, including those outlined in the initial proof of claim filed by the Company in the SunEdison Bankruptcy on September 25, 2016, and on October 7, 2016. Under the Settlement
Agreement, all such claims have been mutually released. Moreover, with certain limited exceptions, any agreements between SunEdison Debtors and SunEdison parties to the Settlement Agreement on the one hand and the Company, on the other hand, have
been deemed rejected without further liability, claims, or damages on the part of the Company. These exceptions included directors and officers liability insurance allocation agreements and certain corporate and project-level transition
services agreements.  F-158




---

Historical Management Services Agreement with SunEdison Historically, general and administrative expensesaffiliate primarily represented costs incurred by SunEdison for services provided to the
Company pursuant to the management services agreement (the SunEdison MSA). Pursuant to the SunEdison MSA, SunEdison agreed to provide or arrange for other service providers to provide management and administrative services to the
Company. As consideration for the services provided, the Company agreed to pay SunEdison a base management fee equal to 2.5% of the Companys cash available for distribution in 2017 but not to exceed $9.0 million. Subsequent to the
SunEdison Bankruptcy, SunEdison continued to provide some of these services, including services related to information technology, human resources, tax, treasury, finance and controllership, but stopped providing or reimbursing the Company for other
services. The Company entered into a corporate-level transition services agreement with SunEdison on September 7, 2017 that covered
the services that SunEdison continued to provide under the SunEdison MSA and retroactively applied to transition services provided since February 1, 2017. The Company paid SunEdison certain monthly fees in exchange for these services at rates
consistent with past practice. Amounts incurred by the Company under this transition services agreement with SunEdison and by SunEdison under the SunEdison MSA totaled $4.5 million for the year ended December 31, 2017, and are reported
within general and administrative expensesaffiliate in the consolidated statements of operations. As discussed above, the SunEdison MSA was rejected without further liability, claims or damages on the part of the Company pursuant to the
Settlement Agreement upon the closing of the Merger. The corporate-level transition services agreement was extended through the end of the fourth quarter of 2017 with respect to certain information technology services. Amounts incurred for these
services subsequent to the Merger closing date on October 16, 2017 are included within general and administrative expenses in the consolidated statements of operations since SunEdison was no longer an affiliate of the Company. Historical O&M and Asset Management Services with SunEdison O&M services, as well as asset management services, were historically provided to the Company substantially by SunEdison pursuant to
contractual agreements. The Company has completed its transition away from SunEdison for these services, except for services provided to its 101.6 MW renewable energy facility in Chile. In the first half of 2017, the Company entered into certain
transition services agreements with SunEdison to facilitate this transition. These transition services agreements allowed the Company, among other things, to hire employees of SunEdison that were performing these project-level services for the
Company and to terminate project-level asset management and O&M services on 10 days advance notice. Total costs incurred for O&M and asset management services from SunEdison were $17.6 million and $26.7 million during the years
ended December 31, 2017 and 2017, respectively, and are reported as cost of operationsaffiliate in the consolidated statements of operations. Amounts incurred for O&M and asset management services from SunEdison subsequent to the
Merger closing date on October 16, 2017 are included within cost of operations in the consolidated statements of operations since SunEdison was no longer an affiliate of the Company.  F-159

Historical Engineering, Procurement and Construction Contracts and Module Warranties SunEdison served as the prime construction contractor for most of the Companys renewable energy facilities acquired from SunEdison
pursuant to engineering, procurement and construction contracts with the Companys project-level subsidiaries. The Company also generally obtained solar module warranties from SunEdison, including workmanship warranties and output guarantees,
for those solar facilities that the Company acquired from SunEdison that utilized SunEdison modules. Third party insurance was procured by SunEdison to back-stop payment of warranty claims for SunEdison modules purchased from January of 2011 through
January of 2017. During the first quarter of 2017, the Company received $7.0 million from SunEdison in satisfaction of outstanding
claims made under engineering, procurement and construction contracts, of which $4.8 million related to the Companys renewable energy facility located in Chile and compensated the relevant project company as the facilitys
performance during the warranty period was below that guaranteed by an affiliate of SunEdison under the applicable EPC contract. These receipts were treated as equity contributions from SunEdison within Net SunEdison investment on the consolidated
statements of stockholders equity for the year ended December 31, 2017. As discussed above, pursuant to the Settlement Agreement entered into with SunEdison, and upon the consummation of the Merger with affiliates of Brookfield on
October 16, 2017, these construction and related contracts were rejected without further liability, claims or damages on the part of the Company. Insurance Allocation Agreements The
Company, TerraForm Global, SunEdison and certain of their respective directors and officers shared $150.0 million of directors and officers liability insurance policies that covered the period from July 15, 2015 to
July 14, 2016 (the D&O Insurance). SunEdison and the independent directors of SunEdison entered into an agreement, dated March 27, 2017 and amended on June 7, 2017, with the Company, TerraForm Global, their respective
current directors (as of that date) and certain of their respective current officers (as of that date) (the YieldCo D&O Parties) related to the D&O Insurance, which included, among other things, an agreement by SunEdison to
consent to proposed settlements of up to $32.0 million to be funded from the D&O Insurance for certain lawsuits against the YieldCo D&O Parties. The agreement was approved by the Bankruptcy Court on June 28, 2017. On August 31, 2017, the Company, TerraForm Global, SunEdison and certain of their respective current and former directors and officers
entered into a second agreement related to the D&O insurance, which provided, among other things, that no party to the second D&O insurance allocation agreement would object to the settlement of the Chamblee Class Action (as discussed
in Note 20. Commitments and Contingencies)with the use of $13.6 million of the D&O insurance. On September 11, 2017, the Bankruptcy Court granted approval of the second D&O insurance allocation. In connection with
the second D&O insurance allocation agreement, the Company and TerraForm Global entered into an agreement pursuant to which TerraForm Global agreed to indemnify and reimburse the Company for certain legal costs and expenses related to the
defense or settlement of the Chamblee Class Action that are not covered by the D&O insurance. In addition to the insurance
allocation agreements, from time to time, the Company agreed to orders or stipulations with SunEdison and TerraForm Global in connection with the SunEdison Bankruptcy related to, among other things, insurance proceeds, interim operating protocols,
bankruptcy filing protocols and other matters. Net SunEdison Investment During the year ended December 31, 2017, SunEdison made net contributions to Terra LLC pursuant to the related party agreements discussed
above and in connection with drop down acquisitions. The following table illustrates the detail of Net SunEdison investment for the year ended December 31, 2017, as reported in the consolidated statements of stockholders equity:  (in thousands)

Represents stock-based compensation cost related to equity awards in the Companys stock which was
allocated to SunEdison and TerraForm Global. (3)
Represents cash received from SunEdison in satisfaction of outstanding claims made under engineering,
procurement and construction contracts as discussed above. 22. (LOSS) EARNINGS PER SHARE Basic (loss) earnings per share is computed by dividing net (loss) income attributable to Class A common stockholders by the number of
weighted average ordinary shares outstanding during the period. Diluted (loss) earnings per share is computed by adjusting basic (loss) income per share for the impact of the equivalent weighted average dilutive common shares outstanding during the
period unless the impact is anti-dilutive. Common equivalent shares represent the incremental shares issuable for unvested restricted Common Stock. Unvested RSAs that contain non-forfeitable rights to distributions are treated as participating
securities and are included in the (loss) earnings per share computation using the two-class method. The two-class method is an earnings allocation formula that treats
participating securities as having rights to earnings that would otherwise have been available to common stockholders. This method determines loss per share based on distributions declared on common stock and participating securities (i.e.,
distributed earnings), as well as participation rights of participating securities in any undistributed earnings. Undistributed losses are not allocated to participating securities since they are not contractually obligated to share in the losses of
the Company. The numerator for undistributed (loss) earnings per share is also adjusted by the amount of deemed distributions related to the accretion of redeemable non-controlling interest since the
redemption value of the non-controlling interest was considered to be at an amount other than fair value (and was considered a right to an economic distribution that differed from other common stockholders)
and as accretion adjustments were recognized in additional paid-in capital and not within net (loss) income attributable to Class A common stockholders. Basic and diluted (loss) earnings per share of the Companys Common Stock for the years ended December 31, 2019, 2018 and 2017 was
calculated as follows:  Year Ended December 31,(In thousands, except per share amounts)

The computation of diluted earnings per share of the Companys Common Stock for the year ended
December 31, 2019, excluded the impact of 191,936 potentially dilutive unvested RSUs outstanding at December 31, 2019, because the effect would have been anti-dilutive. 23. SEGMENT REPORTING The Company has three reportable segments: Solar, Wind, and Regulated Solar and Wind. These segments, which represent the Companys entire
portfolio of renewable energy facilities, have been determined based on the management approach. The management approach designates the internal reporting used by management for making decisions and assessing performance as the source of the
reportable segments. Each of the Companys reportable segments represents an aggregation of operating segments. An operating segment is defined as a component of an enterprise that engages in business activities from  F-161

which it may earn revenues and incur expenses, and that has discrete financial information that is regularly reviewed by the chief operating decision maker (CODM) in deciding how to
allocate resources. The Companys Chief Executive Officer and Chief Financial Officer have been identified as the CODMs. The Companys operating segments consist of: (i) Distributed Generation, North America Solar Utility,
International Solar Utility, which are aggregated into the Solar reportable segment; (ii) Northeast Wind, Central Wind, Texas Wind, Hawaii Wind and International Wind operating segments, which are aggregated into the Wind reportable segment;
and (iii) the Spanish Regulated Solar and Spanish Regulated Wind operating segments that are aggregated within the Regulated Solar and Wind reportable segment. The International Wind, comprising the Companys wind operations in Portugal
and Uruguay, and the Spanish Regulated Solar and Wind operating segments were added during the second quarter of 2018 upon the acquisition of Saeta and represent its entire operations. See Note 3. Acquisitions and Divestitures for additional
details. The operating segments were aggregated as they have similar economic characteristics and meet the aggregation criteria per ASC 280. The CODMs evaluate the performance of the Companys operating segments principally based on operating
income or loss. Corporate expenses include general and administrative expenses, acquisition costs, interest expense on corporate-level indebtedness, stock-based compensation and depreciation expense. All net operating revenues for the years
ended December 31, 2019, 2018, and 2017, were earned by the Companys reportable segments from external customers in the United States (including Puerto Rico), Canada, Spain, Portugal, the United Kingdom, Uruguay and Chile, as
applicable. The following table reflects summarized financial information for the Companys reportable segments for the years ended

Cash and Cash Equivalents The Company is subject to concentrations of credit risk related to the cash and cash equivalents that may exceed the insurable limits in the
related jurisdictions. The maximum exposure to loss due to credit risk would generally equal the stated value of cash and cash equivalents in the above table. The Company places its cash and cash equivalents with creditworthy financial institutions
and, historically, did not experience any losses with regards to balances in excess of insured limits or as a result of other concentrations of credit risk. Accounts Receivable, Net The
Company serves hundreds of customers in three continents, and, in the United States, the Companys customers are spread across various states resulting in the diversification of its customer base. Notwithstanding this diversification, a
significant portion of the Companys offtake counterparties are government-backed entities and public utility companies, which has the potential to impact the Companys exposure to credit risk. Major Customers The following table
reflects operating revenues, net for the years ended December 31, 2019, 2018 and 2017, by specific customers exceeding 10% of total net operating revenues:  Year Ended December 31,2019

The Company earned $338.7 million and $186.7 million from the Spanish Electricity System for the
years ended December 31, 2019, and 2018, respectively, of which $240.7 million and $127.9 million were through collections from the Comisión Nacional de los Mercados y la Competencia (CNMC). These operating revenues
were earned within the Regulated Solar and Wind segment and represented 25.6% and 16.7% of the Companys net consolidated operating revenues for these years, respectively. The CNMC is the state-owned regulator of the Spanish Electricity System
who collects the funds payable, mainly from the tariffs to end user customers, and is responsible for the calculation and the settlement of regulated payments. (2)
The Company earned $93.9 million and $90.3 million operating revenues from the Tennessee Valley
Authority (TVA) for the years ended December 31, 2019, and 2018, respectively. These operating revenues were earned within the Regulated Solar and Wind segment and represented 10.0% and 11.8% of the Companys net consolidated
operating revenues for these years, respectively. The TVA is a corporation wholly-owned by the U.S. government that sells power mainly to wholesale customers in several states in the Southern part on the U.S. (3)
This customer did not exceed 10% of total operating revenue for the year ended December 31, 2019. The amounts receivable from the CNMC and TVA as of December 31, 2019, and 2018, were as follows:  As of December 31,(In thousands)

74,454 If the CNMC or the TVA were to cease to honor their obligations to the Company it would have a material
adverse effect on the Companys business, operating results or financial position. The Companys management believes that the concentration of risk with the CNMC is mitigated by, among other things, the indirect support of the Spanish
government for the CNMCs obligations and, in general, by the regulated rate system in Spain. Similarly, the Companys management believes that the concentration risk of the credit risk with the TVA is mitigated by, among other things, the
indirect support of the U.S. government.  F-165

Derivative Assets The Company is subject to credit risk related to its derivatives to the extent the hedge counterparties may be unable to meet the terms of the
contractual arrangements. The maximum exposure to loss due to credit risk if counterparties fail completely to perform according to the terms of the contracts would generally equal the fair value of derivative assets presented in the above table.
The Company seeks to mitigate credit risk by transacting with a group of creditworthy financial institutions and through the use of master netting arrangements. 25.

During the first quarter of 2018, the Company recorded a reduction of $151.2 million to the non-controlling interests balance and a corresponding allocation of net loss attributable to non-controlling interests due to the change in the tax rate input in the HLBV
methodology used by the Company. As a result of the reduction of the federal income tax rate from 35% to 21% as specified in the Tax Act, the Company allocated significantly lower amounts to certain
non-controlling interests (i.e., tax equity investors) in order to achieve their contracted after-tax rate of return. (3)
As discussed in Note 3. Acquisitions and Divestitures,on June 12, 2018 the Company
acquired approximately 95.28% of the outstanding shares of Saeta, a Spanish renewable power company with over 1,000 MW of wind and solar facilities (approximately 250 MW of solar and 778 MW of wind) located primarily in Spain. The Company acquired
the remaining approximately 4.72% of the shares of Saeta on July 2, 2018. The below table presents selected financial information of Saeta as included in the Companys results for the year ended December 31, 2018:  (In thousands)

During the second quarter of 2018, the Company discontinued hedge accounting for a certain long-dated commodity
contract as it was no longer considered highly effective in offsetting the cash flows associated with the underlying risk being hedged. The gains (losses) in fair value on this commodity contract were recorded in earnings within operating revenues,
net and amounted to $10.8 million, $0.9 million and $(5.3) million for the second, third and fourth quarters of 2018, respectively (see Note 12. Derivatives). (5)
During the fourth quarter of 2018, the Company recorded corrections related to the accretion period related to
changes in the period over which the asset retirement obligations were accreted to their expected future value using the estimate of the future timing of settlement resulting in a reduction in the previously reported accretion and depreciation
expense by $6.3 million and $4.4 million, respectively, as a result of this change.  F-167

26. SUBSEQUENT EVENTS Brookfield Renewable Non-Binding Proposal and Signing of Reorganization Agreement On January 11, 2020, the Company received an unsolicited and non-binding proposal from Brookfield
Renewable Partners L.P., an affiliate of Brookfield, to acquire all of the outstanding shares of Common Stock of the Company, other than the approximately 62% shares held by Brookfield Renewable and its affiliates. The Brookfield Proposal expressly
conditioned the transaction contemplated thereby on the approval of a committee of the Board consisting solely of independent directors and the approval of a majority of the shares held by the Companys stockholders not affiliated with
Brookfield Renewable and its affiliates. Following the Companys receipt of the Brookfield Proposal, the Board formed a Special Committee of non-executive, disinterested and independent directors to,
among other things, review, evaluate and consider the Brookfield Proposal and, if the Special Committee deemed appropriate, negotiate a transaction with Brookfield Renewable or explore alternatives thereto. The Board resolutions establishing the
Special Committee expressly provided that the Board would not approve the transaction contemplated by the Brookfield Proposal or any alternative thereto without a prior favorable recommendation by the Special Committee. Brookfield Renewable holds an
approximately 30% indirect economic interest in TerraForm Power. On March 16, 2020, pursuant to the Brookfield Proposal, the Company
and Brookfield Renewable and certain of their affiliates entered into the Reorganization Agreement for Brookfield Renewable to acquire all of the Companys outstanding shares of Common Stock, other than the approximately 62% currently owned by
Brookfield Renewable and its affiliates. Pursuant to the Reorganization Agreement, each holder of a share of Common Stock that is issued and outstanding immediately prior to the consummation of the Transactions will receive, at each such
shareholders election, 0.381 of a Brookfield Renewable limited partnership unit or of a Class A exchangeable subordinate voting share of Brookfield Renewable Corporation, a Canadian subsidiary of Brookfield Renewable which is expected to
be publicly listed as of the consummation of the Transactions. The Special Committee has unanimously recommended that the Companys unaffiliated shareholders approve the Transactions. Consummation of the Transactions is subject to the non-waivable approval of a majority of the Companys shareholders not affiliated with Brookfield Renewable, receipt of required regulatory approvals and other customary closing conditions. Acquisition of 100 MW Concentrated Solar Power Facilities in Spain On February 11, 2020, TERP Spanish Holdco, S.L.U., a wholly-owned subsidiary of the Company, completed the acquisition of a portfolio of
