INDEPENDENT AUDITORS’ REPORT

The Members’

Terra-Gen Power, LLC

Report on the Financial Statements

We have audited the accompanying combined financial statements of the Alta Wind Portfolio of Terra-Gen Power, LLC, which comprise the combined balance sheets as of December 31, 2013 and 2012, and the related combined statements of operations and comprehensive income (loss), members’ capital, and cash flows for each of the years in the three-year period ended December 31, 2013, and the related notes to the combined financial statements.

Management’s Responsibility for the Financial Statements

Management is responsible for the preparation and fair presentation of these combined financial statements in accordance with U.S. generally accepted accounting principles; this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of combined financial statements that are free from material misstatement, whether due to fraud or error.

Auditors’ Responsibility

Our responsibility is to express an opinion on these combined financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the combined financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the combined financial statements. The procedures selected depend on the auditors’ judgment, including the assessment of the risks of material misstatement of the combined financial statements, whether due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to the entity’s preparation and fair presentation of the combined financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the combined financial statements.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the combined financial statements referred to above present fairly in all material respects, the financial position of the Alta Wind Portfolio of Terra-Gen Power, LLC as of December 31, 2013 and 2012, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2013, in accordance with U.S. generally accepted accounting principles.

(1) Organization and Business of the Company

Terra-Gen Power, LLC (Power), a wholly owned subsidiary of Terra-Gen Power Holdings, LLC, is engaged in the development, construction, ownership, operation, and management of renewable energy projects utilizing wind, geothermal, and solar as fuel for its generating assets. The Alta Wind Portfolio of Terra-Gen Power, LLC (collectively referred to within these combined financial statements as the Company) consists of Alta Wind I, LLC, Alta Wind Holdings, LLC (Alta Holdings), Alta Wind X, LLC, Alta Wind XI, LLC, Alta Realty Investments, LLC (Alta Realty), and Alta Wind Asset Management, LLC (AWAM). These entities are indirect, wholly-owned subsidiaries of Power. The Company is engaged in the ownership, operation, management, and construction of wind renewable energy projects located at the Alta Wind Energy Center (AWEC) in Tehachapi, California. As of December 31, 2013, the Company is engaged in the following activities:

·                  Owning and managing five wind plants (individually, an Operating Entity and, collectively, the Operating Entities).

·                  Construction of two wind plants (individually, a Construction Entity and, collectively, the Construction Entities).

·                  Own the rights to royalty income and leasehold interest (the Leasehold Rights) in leases with certain of the Operating Entities and two third-party wind plants. The Leasehold Rights are owned by Alta Realty and AWAM (collectively known as Leasehold Entities).

The Operating Entities sell all electricity produced to Southern California Edison (Edison) under separate fixed price power purchase agreements (PPAs), with original terms of approximately 25 years, utilizing 290 turbines on leased and owned property.

The following table provides information for each of the Operating Entities as of December 31, 2013:

The following table provides information for each of the Construction Entities as of December 31, 2013:

**                                  The fixed price PPA begins January 1, 2016.

Construction of Alta X and XI began during 2013. As of December 31, 2013, construction was substantially complete and the Construction Entities achieved commercial operations on February 1, 2014. Through December 31, 2015, the Construction Entities are selling energy and renewable energy credits on a merchant basis under a Master Power Purchase and Sale Agreement (the Merchant PPA) with TGP Energy Management, LLC (TGEM), an affiliate. Energy sales under the Merchant PPA are sold into the California Independent System Operator market. The Merchant PPA is effective on the first date of delivery of energy from the Construction Entities and shall continue through December 31, 2015. Beginning on January 1, 2016, the Construction Entities will sell all energy produced to Edison under separate fixed price PPAs, which expire in 2038.

The Operating and Construction Entities represent a portion of AWEC, a 3,000 MW wind development project in the Tehachapi region, which was built in multiple phases by subsidiaries of Power and is located in the largest wind resource area of California approximately 100 miles from Los Angeles. In conjunction with the development of the Operating Entities during 2009 and 2010 and the Construction Entities during 2012, a subsidiary of Power contributed certain assets to the Company at historical cost. The historical cost approximated fair value as the assets and liabilities were recorded at fair value in connection with the affiliate’s acquisition of the AWEC assets in July 2008. The fair value as of the acquisition date was based in part on the work of third-party appraisers engaged to perform valuations of certain of the tangible and intangible assets acquired. The affiliate’s contribution of assets consisted of:

Subsequent events have been evaluated and disclosed as required through the report issuance date of June 16, 2014.

(2) Summary of Significant Accounting Policies

Principles of Combination

The Company was not a legal entity as of December 31, 2013 as direct ownership relationships did not exist among all of the entities included in the Alta Wind Portfolio of Terra-Gen Power, LLC. The combined financial statements include the Operating Entities, Construction Entities, and Leasehold Entities and were prepared using the historical basis of these entities’ assets, liabilities, revenues, and expenses. All intercompany accounts and transactions have been eliminated.

Basis of Presentation

The combined financial statements are prepared in accordance with U.S. generally accepted accounting principles, which requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and members’ capital, and disclosure of contingent assets and liabilities at the date of the combined financial statements and the reported amounts of revenues, and expenses during the period. Actual results could differ from these estimates.

Cash and Cash Equivalents

For purposes of the combined statements of cash flows, the Company considers all money market instruments purchased with an original maturity of three months or less to be cash equivalents.

Restricted Cash and Cash Equivalents

The Company is required to maintain cash balances that are restricted by provisions of their financing and operational agreements. The Company’s financing and operational agreements specify restrictions primarily based on debt service requirements, construction costs, working capital requirements and operating costs.

Revenue Recognition

Revenue from Power Generation:  The Operating Entity PPAs are treated as a variable interest (VI) in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Section 810-10-65, Consolidation, Variable Interest Entities. Income from power purchase agreements for VIs is recognized as income during the period in which electricity is delivered to Edison.

In the event that the PPAs are amended, the Company’s accounting policies would be reassessed in accordance with the guidance established in FASB ASC Topic 605-10-25, Revenue Recognition Overall, and FASB ASC Topic 840-10-15, Leases Overall.

Test Energy:  The Construction Entities began generating energy during the late phases of construction as the wind turbines were being tested and synchronized prior to commercial operations. The Company sold this energy produced on a merchant basis at a variable market rate under a short-term arrangement through commercial operations (Test Energy). The Test Energy was recognized upon delivery of energy to TGEM and was recorded as a reduction in basis of the construction-in-progress. The Construction Entities recognized $80 in Test Energy for the year ended December 31, 2013. The construction of the Operating Entities was completed during 2011 and the Operating Entities recognized $2,487 in Test Energy for the year ended December 31, 2011.

Years ended December 31, 2013, 2012, and 2011

(Dollars in thousands)

Other Revenue:  Included in other revenue is royalty income from two third-party wind plants and the amortization of deferred revenue related to wake impact payments received by certain of the Operating Entities. The royalty income is recognized during the period that the third party project produces energy based on a percent of revenue generated by the third party project. The deferred revenue is recognized on a straight-line basis over the life of the respective PPA.

Concentration of Credit Risk

Financial instruments that are potentially subject to the concentration of credit risk consist primarily of restricted cash and cash equivalents and accounts receivable. As of December 31, 2013 and 2012, all of the Company’s cash balances were deposited with major financial institutions.

Edison accounts for approximately 99.3%, 99.8%, and 99.4% of the Company’s revenue for the years ended December 31, 2013, 2012 and 2011, respectively. Edison also accounts for 93.4% and 97.6% of the Company’s accounts receivable at December 31, 2013 and 2012, respectively. Accounts receivable as of December 31, 2013 and 2012 consist of receivables from Edison for electricity delivered and sold under the PPAs and as of December 31, 2013, for Edison’s reimbursement of costs incurred by the Company during the Operating Entities construction phase (note 4).

Property, Plant, and Equipment, and Depreciation

Property, plant, and equipment consists of costs incurred in connection with the development and construction of the wind plants, the substations, and collection lines. The wind plant assets are depreciated beginning on the commercial operations date using the straight-line method over 25 years, the estimated useful life of the assets. Other property and equipment are depreciated using the straight-line method between 3 and 25 years. Expenditures for maintenance, repairs, and minor parts are charged to expenses as incurred with improvements being capitalized over the remaining useful life of the project. Proceeds from the cash grants and other construction reimbursements (note 4) are accounted for as a reduction in the basis of the property, plant, and equipment upon receipt and the reduction in basis will be depreciated over the remaining useful life of the assets.

Construction-in-Progress

Costs incurred related to the development, permitting, preconstruction, construction, and direct administrative costs are capitalized as construction-in-progress. Interest costs incurred on debt during the construction phase and all deferred financing costs amortized during the construction phase are also capitalized in construction-in-progress. Upon achieving commercial operations, construction-in-progress will be transferred to property, plant, and equipment and be depreciated over their estimated useful lives using the straight-line method. Proceeds from Test Energy have been and will be accounted for as reduction in the basis of construction-in-progress upon receipt. The reduction in basis will be depreciated over the remaining useful life of the assets.

Interest Capitalization

The Company’s policy is to capitalize interest cost incurred on debt during the construction of major projects. Capitalization is discontinued when a project achieves commercial operation or when construction is terminated. A reconciliation of total interest cost to interest expense as reported in the combined statements of operations is as follows:

Intangible Assets

Intangible assets consist of transmission queue rights and the Leasehold Rights. The Company amortizes the transmission queue rights using the straight-line method over their respective useful lives of approximately 25 years and the Leasehold Rights over the Operating Entity or third-party wind plant’s power purchase agreement lives through 2035.

Long-Lived Assets and Intangible Assets

In accordance with Impairment or Disposal of Long-Lived Assets Subsections of FASB ASC Subtopic 360-10, Property, Plant, and Equipment—Overall, long-lived assets, such as property, plant, and equipment and purchased intangible assets subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If circumstances require a long-lived asset or asset group be tested for possible impairment, the Company first compares undiscounted cash flows expected to be generated by the asset or asset group to its carrying value. If the carrying value of the long-lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying value exceeds its fair value. Fair value is determined through various valuation techniques including discounted cash flow models, quoted market values, and third-party independent appraisals, as considered necessary.

Deferred Financing Costs

Deferred financing costs consist of certain bank fees and legal costs related to the issuance of various debt instruments. Deferred financing costs are being amortized using the effective-interest method over the life of the respective debt instruments. Amortization of deferred financing costs during construction is capitalized in construction-in-progress.

Asset Retirement Obligations

The Company has asset retirement obligations to perform certain asset retirement activities. The liabilities are initially measured at fair value and subsequently will be adjusted for accretion expense and changes in the amount or timing of the estimated cash flows. The corresponding asset retirement costs are capitalized as part of the carrying amount of the related long-lived asset and will be depreciated over the asset’s useful life.

Fair Value Measurements

The Company utilizes valuation techniques that maximize the use of observable inputs. The Company determines fair value based on assumptions that market participants would use in pricing an asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels:

·                  Level 1—Consists of assets or liabilities whose value is based on unadjusted quoted prices in active markets at the measurement date.

·                  Level 2—Consists of assets or liabilities valued using industry standard models and based on prices, other than quoted prices within Level 1, that are either directly or indirectly observable as of the measurement date.

·                  Level 3—Consists of assets or liabilities whose fair value is estimated based on internally developed models or methodologies using inputs that are generally less readily observable and supported by little, if any, market activity at the measurement date.

Interest Rate Swap Agreements

The Company utilizes interest rate swap agreements to lock in a specified interest rate on a portion of its long-term debt. The interest rate swap agreements are recorded at fair value on the accompanying combined balance sheets. The Company did not meet the requirements for hedge accounting in accordance with FASB ASC Topic 815, Derivatives and Hedging, and, accordingly, has recorded the change in the fair value of the interest rate swaps in unrealized gain on interest rate swap agreements in the combined statements of operations. Amounts paid on the interest rate swap agreements have been recorded as interest expense in the combined statements of operations.

As a result of the use of derivative financial instruments, such as interest rate swaps, the Company is exposed to the risk that counterparties will fail to meet their contractual obligations. To mitigate the counterparty credit risk, the Company has a policy of entering into contracts only with major financial institutions selected based upon their credit ratings and other financial factors.

Fair Value of Financial Instruments

The carrying amounts of cash and cash equivalents, restricted cash and cash equivalents, accounts receivable, prepaid expenses, other current assets, materials and supplies, amounts due from affiliates, accounts payable, accrued liabilities, accrued construction costs, accrued interest, and amounts due to affiliates approximated fair value as of December 31, 2013 and 2012 because of the relatively short maturities of these instruments.

(Dollars in thousands)

Income Taxes

No income taxes or tax benefits have been recorded in the Company’s combined financial statements because such taxes, if any, are the responsibility of the members.

Risks and Uncertainties

The Company is subject to a variety of factors, including the economy, the regulatory environment, the electricity markets, and the availability of capital resources. As with any power generation facility, operation of the Company’s wind portfolio and the third-party wind plants related to the Leasehold Entities involves risk, including the performance of the facilities below expected levels of efficiency and output, shut downs due to breakdown or failure of equipment or processes, violation of permit requirements, operator error, labor disputes, weather interferences, or catastrophic events such as fires, earthquakes, floods, explosions, or other similar occurrences affecting a power generation facility or its power purchasers. The occurrence of any of these events could significantly reduce or eliminate revenues generated by these facilities or significantly increase the expenses of each of the facilities, adversely impacting the Company’s ability to make payments of principal and interest on its debt or finance lease obligations when due.

Commitments and Contingencies

Liabilities for loss contingencies arising from claims, assessments, litigation, fines, and penalties and other sources are recorded when it is probable that a liability has been incurred and the amount can be reasonably estimated. Legal costs incurred in connection with loss contingencies are expensed as incurred.

(3) Restricted Cash and Cash Equivalents

The Company is required to maintain restricted cash accounts in accordance with certain of its financing and operational agreements. Restricted cash and cash equivalents at December 31, 2013 and 2012 consist of the following:

(4) Property, Plant, and Equipment

Property, plant, and equipment at December 31, 2013 and 2012 consists of the following:

Depreciation expense for the year ended December 31, 2011 was $51,264.

Cash Grant Program:  Construction and financing of the Operating Entities’ wind plants was arranged with the expectation of applying for and receiving cash grants under the American Recovery and Reinvestment Act of 2009 (ARRA). Under ARRA, owners of these wind plants are eligible to receive a cash grant from the U.S. Department of Treasury (U.S. Treasury) representing 30% of the eligible costs, as defined (the Cash Grant). At the request of the Operating Entities, the Owner Lessors (note 9) filed cash grant applications with the U.S. Treasury aggregating $654,881, which represents 30% of the Owner Lessors’ eligible cost to acquire these wind plants. During 2011, the Owner Lessors received from the U.S. Treasury and paid to the Operating Entities partial payments aggregating $467,971 under the grant program, which were classified as a reduction in the carrying value of the property, plant, and equipment and as rental payments under the finance lease obligations (note 9). At the request of the Operating Entities, certain Owner Lessors filed claims against the U.S. Treasury to recover what the Operating Entities believe to be shortfalls in the grant proceeds. Any additional proceeds received by the Operating Entities will be treated as reduction of the wind plant asset when received.

(Dollars in thousands)

Reimbursements:  Included in the 2013 reimbursement is a settlement executed during December 2013 between Edison and the Operating Entities related to certain costs incurred by the Operating Entities during the construction phase of its wind plants. The settlement requires Edison to reimburse the Operating Entities for $1,793 of these costs. This amount was included in accounts receivable as of December 31, 2013 and was received during January 2014.

The 2012 reimbursements consist of refunds of $3,531 primarily from Edison and $4,001 from affiliates. The Edison payments were related to the final costs to construct the interconnect wind plants pursuant to a letter agreement between the Company, Edison, and the California Independent System Operator. The affiliate payments related to a Shared Facilities Agreement (SFA) between the Operating Entities, certain affiliates, and Terra-Gen Operating Company, LLC (TG Operating) and a Long-Term Interconnection Co- tenancy Agreement between the Company and certain affiliates (the LGIA—note 12). Under the terms of these agreements, the affiliates are required to reimburse the Company for capital expenditures previously incurred by the Company for the construction of shared assets including substations, operations and maintenance facilities, and interconnect facilities. The Company may receive additional funds as other AWEC phases are successfully developed. All reimbursements are treated as a reduction in the basis in the wind plant and depreciated over the remaining useful life of the wind plant.

(5) Construction-in-Progress

Construction-in-progress at December 31, 2013 and 2012 consists of the following:

Additions:  The 2013 additions include the construction of the Alta X and XI wind plants. These entities will utilize a federal government program supporting renewable energy, which enhance the economic feasibility of developing the project. The key federal programs expected to benefit Alta X and XI are production tax credits under the American Tax Relief Act of 2012 (Tax Relief Act) and accelerated tax depreciation for renewable energy property. Under the Tax Relief Act, the owners of Alta X and XI are eligible for a federal tax credit equal to 2.3 cents per kilowatt-hour of energy produced for the first ten years of operation.

Included in additions for the year ended December 31, 2013 is $68,934 in accrued costs, which were paid during 2014.

(6) Intangible Assets

Interconnection Queue Rights:  In an effort to meet its future renewable energy goals, Edison commenced construction on the $1,800,000 Tehachapi Renewable Transmission Project, a series of transmission upgrades that are designed to deliver approximately 4,500 MW of generation from the Tehachapi region to the Los Angeles basin. The value of the interconnection queue rights is derived from the Company’s rights in certain large generator interconnection agreements and their positions in the California System Independent Operator Corporation interconnection queue (note 1).

Leasehold Rights:  Alta Realty and AWAM, through a series of transactions, acquired Leasehold Rights in certain parcels of real property located in Kern County, California, and owned by third parties (collectively, the Property Owners), which are subject to the long-term lease agreements with the Operating Entities. The acquisitions of the Leasehold Rights for the years ended December 31, 2013 and 2012 totaled $9,034 and $10,489, respectively. As part of the acquisitions, the Property Owners assigned 100% of the rights in the royalty income to Alta Realty and AWAM that the Operating Entities are required to pay the Property Owners during the term of the lease agreements.

The aggregate intangible assets at December 31, 2013 and 2012 consist of the following:

Amortization expense for the year ended December 31, 2011 was $3,538. The estimated annual amortization of the intangible assets over the next five years is approximately $5,077 per year.

(7) Deferred Financing Costs

Deferred financing costs consist of certain legal and bank fees related to the issuance of various debt instruments described in note 9. Deferred financing costs are being amortized using the effective-interest method over the life of the respective debt instruments. The following table presents the activity for deferred financing costs for the years ended December 31, 2013 and 2012:

(Dollars in thousands)

The amortization of deferred financing costs for the year ended December 31, 2011 was $9,321, of which $6,287 was expensed and included in the accompanying combined statement of operations and $3,034 was capitalized and included in construction in progress in the accompanying combined balance sheet.

Alta X and XI:  During 2013, Alta X and XI incurred new deferred financing costs of $13,846 related to the issuance of new credit agreements. Amortization of deferred financing costs during construction of Alta X and XI totaled $1,022 for the year ended December 31, 2013.

AWAM:  During 2013, AWAM incurred new deferred financing costs of $861 related to the issuance of a new credit agreement.

(8) Note Receivable

In conjunction with the development of its wind plant, Alta XI entered into lease agreements for the property that the turbines will be located on (note 13). In conjunction with obtaining one of the leases, Alta XI issued a $2,100 note receivable to its landowner. The note receivable accrues interest at 8.0%, which is added to the unpaid principal of the note receivable on a monthly basis. Repayment of the note receivable is equal to 40% of the royalties due to the landowner, as defined, with a minimum payment of $30 per month beginning in June 2014. For the year ended December 31, 2013, the Company recognized $115 in interest income related to this note receivable, all of which has been capitalized into the note receivable principal. The long-term and current portion of the note receivable of $2,005 and $210, respectively, are included in other assets and prepaids and other current assets, respectively, in the accompanying combined balance sheet as of December 31, 2013.

The Company’s management has estimated the fair value of its finance lease obligations based on a discounted cash flow analysis using interest rates currently available for borrowings not involving a leveraged lease.

The finance lease obligations are subject to certain restrictive covenants that, among other things, limit the borrowers’ ability to incur additional indebtedness, release funds from reserve accounts, maintain reserve accounts, make distributions, create liens, and enter into any transaction of merger or consolidation.

The finance lease obligations were issued under separate leveraged lease transactions whereby the Operating Entities sold and leased back undivided interests in specific assets of the project.

The leveraged lease transactions are accounted for as a financing due to Operating Entities continued involvement with the property sold and leased back. Each Owner Lessor is beneficially owned by an equity investor (each, an Owner Participant).
