Basis of Presentation	Basis of Presentation The condensed consolidated financial statements are prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and the rules and regulations of the Securities and Exchange Commission (“SEC”). Any reference in these notes to applicable guidance is meant to refer to the authoritative U.S. GAAP as found in the Accounting Standards Codification (“ASC”) and the Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”).

ADK LLC’s condensed consolidated financial statements include its wholly-owned subsidiaries indie Services Corporation, indie LLC and indie City LLC, all California entities, Ay Dee Kay Limited, a private limited company incorporated under the laws of Scotland, indie GmbH and Symeo GmbH, both of which are private limited liability companies incorporated under the laws of Germany, indie Kft, a limited liability company incorporated under the laws of Hungary, TeraXion Inc., a company incorporated under the laws of Canada, indie Semiconductor Israel Ltd., a private limited company incorporated under the laws of Israel, Ay Dee Kay S.A., a limited liability company incorporated under the laws of Argentina, indie Semiconductor Morocco, a limited liability company under the laws of Morocco, indie Semiconductor Japan KK, a limited liability company under the laws of Japan, indie Semiconductor Korea Branch, a limited liability company under the laws of Korea, Wuxi indie Microelectronics (“Wuxi”), a Chinese entity with 55% voting controlled and 38% owned by the Company as of June 30, 2023 and Wuxi’s wholly-owned subsidiaries, indie Semiconductor Suzhou, indie Semiconductor HK, Ltd and Shanghai Ziying Microelectronics Co., Ltd. All significant intercompany accounts and transactions of the subsidiaries have been eliminated in consolidation.

Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements In June 2016, the FASB amended guidance related to impairment of financial instruments as part of ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which replaces the incurred loss impairment methodology with an expected credit loss model for which a company recognizes an allowance based on the estimate of expected credit loss. This ASU requires entities to measure the impairment of certain financial instruments, including accounts receivable, based on expected losses rather than incurred losses. This ASU is effective for fiscal years beginning after December 15, 2022, with early adoption permitted, and will be effective for the Company beginning in 2023. The Company adopted the guidance as of January 1, 2023 and the impact to its condensed consolidated financial statements was not material.
