(2) Summary of Significant Accounting Policies

Principles of Combination

The Company was not a legal entity as of June 30, 2014 as direct ownership relationships did not exist among all of the entities included in the Alta Wind Portfolio. The combined financial statements include the Operating 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 (U.S. GAAP), 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.

Unaudited Interim Financial Information

The accompanying unaudited combined financial statements do not include all of the information and footnotes required by U.S. GAAP for complete combined financial statements. In the opinion of management, the interim financial information reflects all adjustments of a normal recurring nature, necessary for a fair presentation of the Company’s financial position, results of operations and cash flows for the periods presented. Interim results may not be indicative of the results for any other interim period or the entire fiscal year. The unaudited combined financial statements should be read in conjunction with the audited combined financial statements of the Company for the year ended December 31, 2013.

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 or operating leases in accordance with FASB ASC Topic 980-605-25, Revenue Recognition, and FASB ASC Topic 840-10-15. Leases Overall. Energy revenues for VIs and leases are recognized as income during the period in which electricity is delivered to the power purchasers.

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: Alta X and Alta XI 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. Alta X and XI recognized $1,093 in Test Energy for the six months ended June 30, 2014, prior to the facilities’ commercial operation date of February 1, 2014.

(Dollars in thousands)

Renewable Energy Credits: Alta X and Alta XI sell REC’s under the Merchant PPA with TGEM. REC’s are recognized as revenue after a certification has been issued by an independent third party and the REC’s have been delivered to TGEM.

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 June 30, 2014, all of the Company’s cash balances were deposited with major financial institutions.

Edison accounts for approximately 83.0% and 86.0% of the Company’s revenue for the three and six months ended June 30, 2014, respectively and TGEM accounts for 15.8% and 13.0% of the Company’s revenues for the three and six months ended June 30, 2014, respectively. Edison accounts for approximately 99.0%, of the Company’s revenue for the three and six months ended June 30, 2013.

Accounts receivable as of June 30, 2014, primarily consist of receivables from Edison for electricity delivered and sold under the PPAs with Edison accounting for 96.0% of the Company’s accounts receivable at June 30, 2014.

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 three and 25 years. Proceeds from cash grant proceeds are accounted for as a reduction in the basis of property, plant and equipment upon receipt and the reduction in basis is depreciated over the remaining useful life of the assets. 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.

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 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.

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 Swaps

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 loss 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.

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 consist of the following:

	June 30, 2014		December 31, 2013

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 mergers or consolidation without consent. As of June 30, 2014, Alta I and Alta Wind Holdings were in compliance with the terms, covenants, and provisions of their respective loan agreements.

The finance lease obligations were issued under separate leveraged lease transactions whereby the respective Operating Entities sold and leased back undivided interests in specific assets of the project. As part of the leveraged lease, separate Delaware statutory trusts (collectively, the Owner Lessors) are each owners of an undivided interest in the assets sold and leased back. 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).

After the Owner Lessors acquire their respective undivided interests, the Owner Lessors leased these undivided interests to the applicable Operating Entities under separate facility lease agreements (each, a Facility Lease). The terms and conditions of each Facility Lease are substantially similar. The Operating Entities make rental payments as stipulated in each facility lease agreement on a recurring basis sufficient for the Owner Lessors to make the required payments of principal and interest on debt that was issued under each transaction and to provide a return on the Owner Participant’s equity funding.

The derivative assets and liabilities arise from interest rate swap agreements at Alta X, Alta XI and AWAM. The Company utilizes interest rate swap agreements to lock in specified interest rates on its floating rate debt. The Company did not elect hedge accounting and the swap agreements have been deemed ineffective in offsetting cash flows attributable to the hedged risk. The Company carries these swap agreements in its balance sheet and recognizes the change in fair value through earnings. For the three and six months ended June 30, 2014, the Company recognized approximately $9,022 and $19,550, respectively, of unrealized losses on the swap agreements. For the three and six months ended June 30, 2013, the Company recognized approximately $9,669 and $9,669, respectively, of unrealized gains on the swap agreements. The unrecognized losses and gains are representing cash flow hedge ineffectiveness arising from differences between the terms of the interest rate swap agreements and the hedged debt obligations. These amounts were recorded as an unrealized loss and gain on interest rate swap agreements in the accompanying statement of operations for the three and six months ended June 30, 2014 and 2013, respectively.
