Desert Stateline Holdings, LLC








We have audited the accompanying financial statements of Desert Stateline Holdings, LLC and Subsidiary, which comprise the consolidated balance sheets as of December 31, 2017 and 2016, and the related consolidated statements of income, changes in members' equity, and cash flows for the years then, and the related notes to the consolidated financial statements.





Management's Responsibility for the Consolidated Financial Statements





Management is responsible for the preparation and fair presentation of these consolidated financial statements in conformity with accounting principles generally accepted in the United States of America; this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of consolidated 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 consolidated 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 consolidated financial statements are free from material misstatement.





An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the consolidated financial statements. The procedures selected depend on the auditors' judgment, including the assessment of the risks of material misstatement of the consolidated 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 consolidated 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 consolidated 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 consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of Desert Stateline Holdings, LLC and Subsidiary as of December 31, 2017 and 2016, and the consolidated results of their income and their cash flows for the years then ended in accordance with accounting principles generally accepted in the United States of America.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 Desert Stateline Holdings, LLC and Subsidiary





1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES





Desert Stateline Holdings, LLC (Desert Stateline Holdings) is a holding company that was formed on August 12, 2015 and owns 100% of the membership interests of Desert Stateline, LLC (Desert Stateline, and collectively with Desert Stateline Holdings, the Company).  Desert Stateline was formed on May 18, 2009 for the purpose of developing, constructing, owning and operating a utility-scale solar photovoltaic facility with a capacity of approximately 300 megawatts (MW) located in San Bernardino County, California.





The Company is a partnership with Class A membership interests owned by a wholly-owned subsidiary of Southern Power Company (SPC or Class A Member), and Class B membership interests owned by a wholly-owned subsidiary of 8point3 Operating Company, LLC (Class B Member).





Basis of Presentation





The consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles (GAAP).





Principles of Consolidation





The accompanying consolidated financial statements include the accounts and results of operations of the Company and its wholly-owned subsidiary. All intercompany accounts and transactions have been eliminated in consolidation.





Use of Estimates





The preparation of consolidated financial statements requires the use of estimates, and actual results may differ.





Recently Issued Accounting Standards





In 2014, the FASB issued ASC 606, Revenue from Contracts with Customers (ASC 606), replacing the existing accounting standard and industry specific guidance for revenue recognition with a five-step model for recognizing and measuring revenue from contracts with customers. The underlying principle of the standard is to recognize revenue to depict the transfer of goods or services to customers at the amount expected to be collected. The new standard also requires enhanced disclosures regarding the nature, amount, timing, and uncertainty of revenue and the related cash flows arising from contracts with customers.





The Company has completed the evaluation of all revenue streams, which are derived from the purchase power agreement (PPA), and determined the adoption of ASC 606 will not change the current timing or amounts of revenue recognized in the Company's financial statements. The PPA is excluded from the scope of ASC 606 and included in the scope of the current leasing guidance (ASC 840).





The new standard is effective for periods beginning after December 15, 2018 for non-public companies and early adoption is permitted. The Company intends to use the modified retrospective method of adoption effective January 1, 2018. The Company has also elected to utilize practical expedients which allow it to apply the standard to open contracts at the date of adoption and to reflect the aggregate effect of all modifications when identifying performance obligations and allocating the transaction price for contracts modified before the effective date. The adoption of ASC 606 will not result in a cumulative adjustment as of the adoption date.





In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (ASU 2016-02). ASU 2016-02 requires lessees to recognize on the balance sheet a lease liability and a right-of-use asset for all leases. ASU 2016-02 also changes the recognition, measurement, and presentation of expense associated with leases and provides clarification regarding the identification of certain components of contracts that would represent a lease. The accounting required by lessors is relatively unchanged. ASU 2016-02 is effective for fiscal years beginning after December 15, 2019 for non-public companies and early adoption is permitted. The Company will adopt the new standard effective January 1, 2019.





The Company has completed a detailed inventory and analysis of its leases, which comprise the PPA and land leases for its renewable generation facilities. While the Company has not yet determined the ultimate impact, adoption of ASU 2016-02 is expected to have a significant impact on the Company's balance sheet for lessee arrangements. See Note 4 for details of the Company’s undiscounted lease commitment.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 Desert Stateline Holdings, LLC and Subsidiary





Concentration of Credit Risk





The entire output of the solar facility is contracted under a 20-year PPA with Southern California Edison Company resulting in a significant concentration of credit risk as it relates to the customer accounts receivable. However, the Company does not believe significant credit risk exists at December 31, 2017 due to the creditworthiness of the counterparty. There are no past due amounts from the counterparty at December 31, 2017.





Cash





The Company considers unrestricted cash on hand and deposits in banks to be cash.





Income Taxes





The Company and its subsidiary are limited liability companies treated as a partnership and a single-member disregarded entity, respectively, for income tax purposes. Therefore, federal and state income taxes are not recognized in these consolidated financial statements.





Property, Plant, and Equipment





Property, plant, and equipment (PP&E) is stated at original cost, less accumulated depreciation. Capital additions and betterments that increase the useful lives of the assets are capitalized. Solar facility equipment and related assets are depreciated over their estimated useful lives of up to 35 years on a straight-line basis.





Asset Retirement Obligations





The Company’s asset retirement obligations (ARO) relate to the leased land where the solar facility is located. Upon termination of the lease, the land is required to be restored to an agreed-upon condition. The Company’s AROs are based on future estimated costs associated with the dismantlement, demolition, and removal of the solar facility and could differ significantly when they are incurred.





AROs are computed as the present value of the ultimate costs for an asset’s future retirement and are recorded in the period in which the liability is incurred and estimable, and are then accreted to their future value. Costs are capitalized as part of the related long-lived asset and depreciated over 35 years. During 2017, future estimated costs were adjusted and are reflected as a cash flow revision in the table below. Details of the AROs included in the consolidated balance sheet are as follows:


December 31,(in thousands)20172016Balance, at beginning of period$7,439$870Liability incurred—6,430Accretion expense274139Cash flow revision(1,058)—Balance, at end of period$6,655$7,439





Long-Lived Assets and Intangibles





The Company’s long-lived assets include PP&E and the PPA intangible.  The Company evaluates impairment of these long-lived assets when events or changes in circumstances indicate that the carrying values may not be recoverable. The determination of whether an impairment has occurred is based on an estimate of undiscounted future cash flows compared to carrying value. If the estimated undiscounted future cash flows are less than the carrying value, the fair value of the asset is determined and an impairment loss is recorded. During the years ended December 31, 2017 and 2016, there were no impairment charges recorded.

The Company commenced the recognition of revenue upon commercial operation of each phase of the facility at various dates from December 2015 through July 2016.
