Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

There have been no changes in our accounting policies from those reported in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020. We have expanded our accounting policy relating to foreign currency transactions as follows:

Foreign Currency Transactions

The functional currencies of most of our foreign subsidiaries are the U.S. dollar since the subsidiaries are considered financially and operationally integrated with their domestic parent. For these subsidiaries, the foreign currency monetary assets and liabilities are remeasured into U.S. dollars at end-of-period exchange rates. Any currency transaction gains and losses are included as a component of other expense in our condensed consolidated statements of operations.

The functional currency of our joint venture in the Republic of Korea is the local currency, the South Korean won ("KRW"), since the joint venture is financially independent of its U.S. parent and the KRW is the currency in which the joint venture generates and expends cash. Assets and liabilities of this entity are translated at the rate of exchange at the balance sheet date. Revenues and expenses are translated at the weighted average rate of exchange during the period. For this entity, translation adjustments resulting from the process of translating the KRW financial statements into U.S dollars are included in other comprehensive loss. Translation adjustments attributable to noncontrolling interests are allocated to and reported as part of the noncontrolling interests in the condensed consolidated financial statements.

Recent Accounting Pronouncements

Other than the adoption of the accounting guidance mentioned below, there have been no other significant changes in our reported financial position or results of operations and cash flows resulting from the adoption of new accounting pronouncements.

Accounting Guidance Implemented in 2021

In August 2020, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40) ("ASU 2020-06"). The new standard simplifies the accounting for convertible instruments by eliminating the conversion option separation model for convertible debt that can be settled in cash and by eliminating the measurement model for beneficial conversion features. The guidance is effective for fiscal years beginning after December 15, 2021, with early adoption permitted as early as fiscal years (including interim periods) beginning after December 15, 2020. Consequently, a convertible debt instrument will be accounted for as a single liability measured at its amortized cost, as long as no other features require bifurcation and recognition as derivatives. There will no longer be a debt discount representing the difference between the carrying value, excluding issuance costs, and the principal of the convertible debt instrument and, as a result, there will no longer be interest expense from the amortization of the debt discount over the term of the convertible debt instrument. The amendments in this update also require the if-converted method to be applied for all convertible instruments when calculating diluted earnings per share.

We elected to early adopt ASU 2020-06 as of January 1, 2021 using the modified retrospective transition method, which resulted in a cumulative-effect adjustment to the opening balance of accumulated deficit on the date of adoption. Prior period condensed consolidated financial statements were not restated upon adoption.

Upon adoption of ASU 2020-06, the Company combined the previously separated equity component with the liability component of our 2.5% Green Convertible Senior Notes due August 2025. These components are now together classified as Recourse debt, thereby eliminating the subsequent amortization of the debt discount as interest expense. Similarly, the portion of issuance costs previously allocated to equity was reclassified to debt and will be amortized as interest expense. Accordingly, we recorded a decrease to Accumulated deficit of $5.3 million, a decrease to Additional paid-in capital of $126.8 million, and an increase to Recourse debt, non-current of approximately $121.5 million.

There is no deferred tax impact related to the adoption of ASU 2020-06 due to our full valuation allowance.

Accounting Guidance Not Yet Adopted

Cessation of LIBOR - In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848) Facilitation of the Effects of Reference Rate Reform on Financial Reporting ("ASU 2020-04"), which provides optional expedients for a limited period of time for accounting for contracts, hedging relationships, and other transactions affected by the London

Interbank Offered Rate ("LIBOR") or other reference rate expected to be discontinued. ASU 2020-04 is effective immediately and may be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2022. We are currently evaluating the impact of the adoption of ASU 2020-04 on our consolidated financial statements.
