Members


SG2 Holdings, LLC








We have audited the accompanying financial statements of SG2 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 ended, 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 SG2 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
 SG2 Holdings, LLC and Subsidiary





1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES





SG2 Holdings, LLC (SG2 Holdings) is a holding company that was formed on September 5, 2014 and on October 22, 2014 acquired 100% of the membership interests of SG2 Imperial Valley, LLC (Imperial Valley, and collectively, the Company). Imperial Valley was formed on December 13, 2011 for the purpose of developing, constructing, owning and operating a utility-scale solar photovoltaic facility with a capacity of approximately 150 megawatts (MW) located in Imperial County, California, which began commercial operation on November 26, 2014.





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
 SG2 Holdings, LLC and Subsidiary





Concentration of Credit Risk





The entire output of the facility is contracted under a 25-year PPA with San Diego Gas and Electric Company resulting in a significant concentration of credit risk as it relates to the customer accounts receivable. In addition, the PPA requires that a portion of the revenues are collected directly from the California Independent System Operator. However, the Company does not believe significant credit risk exists at December 31, 2017 due to the creditworthiness of the counterparties. There are no past due amounts from the counterparties 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. Details of the AROs included in the consolidated balance sheets are as follows:


December 31,(in thousands)20172016Balance, at beginning of period$6,172$5,896Accretion expense289276Balance, at end of period$6,461$6,172





Long-Lived Assets





The Company’s long-lived assets include PP&E.  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.

Prepaid Transmission Services





In conjunction with the acquisition of Imperial Valley, the Company acquired a long-term prepaid for transmission services representing network and transmission upgrades that will be reimbursed to the Company through reductions to transmission invoices from the Imperial Irrigation District over 25 years from the acquisition date. The prepaid was recorded at fair value at the acquisition date and subsequently adjusted in 2017 with a charge of $2.4 million reflected in other expense on the consolidated statements of income for the year ended December 31, 2017. At December 31, 2017 and 2016, $1.2 million and $3.2 million is recorded in prepaid expenses within current assets and $14.6 million and $15.7 million is recorded in noncurrent assets, respectively, in the consolidated balance sheets.





Revenues





The Company is a lessor under the terms of a PPA for the sale of electricity and green attributes. The PPA has been evaluated and classified as an operating lease. Under this agreement, revenues are accounted for as contingent revenues and, therefore, the Company recognizes revenues based upon rates specified in the PPA when electricity is delivered. The Company commenced the recognition of revenue upon commercial operation of the facility on November 26, 2014.





Reclassification





Certain amounts reported in prior years have been reclassified to conform to the presentation at December 31, 2017. Total members’ equity, net income, and total cash flows are unchanged due to these reclassifications.





2. MEMBERS’ CAPITAL





SG2 Holdings operates under the amended Limited Liability Company Agreement dated November 26, 2014.





The Class A Member owns 100% of the Class A membership interests of SG2 Holdings and is entitled to 51% of all cash distributions from SG2 Holdings. In addition, the Class A Member is entitled to substantially all of the federal tax benefits with respect to the solar facility. The Class B Member owns 100% of the Class B membership interests of SG2 Holdings and is entitled to 49% of all cash distributions from SG2 Holdings.





3. RELATED-PARTY TRANSACTIONS





The Company has entered into an operations and maintenance agreement with First Solar Electric (California), Inc., a wholly-owned subsidiary of First Solar, Inc., that expires in 2024 to provide operations and maintenance services. First Solar, Inc. owns a noncontrolling 28.0% limited liability company interest in the Class B Member. Expenses recorded during the years ended December 31, 2017 and 2016 were $3.2 million and $3.1 million, respectively. At both December 31, 2017 and 2016, $0.8 million was included in accounts payable - affiliated in the consolidated balance sheets.





The Company has also entered into an ongoing management service agreement with Southern Power Company to provide management and general and administrative services. Expenses recorded for the years ended December 31, 2017 and 2016 were $0.3 million in both years. At December 31, 2017 and 2016, $23,000 and $25,000, respectively, was included in accounts payable - affiliated in the consolidated balance sheets.





At December 31, 2017, SPC had $11.0 million of parent guarantees, $5.0 million of surety bonds, and $0.1 million of cash collateral issued on behalf of the Company. Fees charged by SPC for these arrangements were $0.4 million for both years ended December 31, 2017 and 2016.





4. COMMITMENTS AND CONTINGENCIES





Operating Lease





The Company is obligated under a 30-year, non-cancelable land lease for its solar facility which initially expires in 2043, but contains a 10-year renewal option and inflation-adjusted rent escalation clauses. The related rentals are recognized on a straight-line basis. Rent expense for the years ended December 31, 2017 and 2016 was approximately $1.1 million and $1.6 million, respectively. The Company includes lease extensions that cover the useful life of the solar facility in its computation of minimum lease payments.
