APTIV PLCNOTES TO CONSOLIDATED FINANCIAL STATEMENTS1. GENERALGeneral and basis of presentation—“Aptiv,” the “Company,” “we,” “us” and “our” refer to Aptiv PLC (formerly known as Delphi Automotive PLC), a public limited company formed under the laws of Jersey on May 19, 2011, which completed an initial public offering on November 22, 2011, and its consolidated subsidiaries. On December 4, 2017, following the spin-off of Delphi Technologies, the Company changed its name to Aptiv PLC and its NYSE symbol to “APTV.”The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”).Nature of operations—Aptiv is a leading global technology and mobility architecture company primarily serving the automotive sector. We deliver end-to-end mobility solutions enabling our customers' transition to more electrified, software-defined vehicles. We design and manufacture vehicle components and provide electrical, electronic and active safety technology solutions to the global automotive and commercial vehicle markets.

2. SIGNIFICANT ACCOUNTING POLICIESConsolidation—The consolidated financial statements include the accounts of Aptiv and the subsidiaries in which Aptiv holds a controlling financial or management interest and variable interest entities of which Aptiv has determined that it is the primary beneficiary. Aptiv’s share of the earnings or losses of non-controlled affiliates, over which Aptiv exercises significant influence (generally a 20% to 50% ownership interest), is included in the consolidated operating results using the equity method of accounting. When Aptiv does not have the ability to exercise significant influence (generally when ownership interest is less than 20%), investments in non-consolidated affiliates without readily determinable fair value are measured at cost, less impairments, adjusted for observable price changes in orderly transactions for identical or similar investments of the same issuer, while investments in publicly traded equity securities are measured at fair value based on quoted prices for identical assets on active market exchanges as of each reporting date. The Company monitors its investments in affiliates for indicators of other-than-temporary declines in value on an ongoing basis. If the Company determines that such a decline has occurred, an impairment loss is recorded, which is measured as the difference between carrying value and estimated fair value. Estimated fair value is generally determined using an income approach based on discounted cash flows or negotiated transaction values.Intercompany transactions and balances between consolidated Aptiv businesses have been eliminated.During the years ended December 31, 2021, 2020 and 2019, Aptiv received dividends of $6 million, $9 million and $9 million, respectively, from its equity method investments. The dividends were recognized as a reduction to the investment and represented a return on investment included in cash flows from operating activities.Aptiv's equity investments without readily determinable fair value totaled $30 million and $113 million as of December 31, 2021 and 2020, respectively, and are classified within other long-term assets in the consolidated balance sheets. Aptiv's investments in publicly traded equity securities totaled $66 million as of December 31, 2021 and are classified within other long-term assets in the consolidated balance sheet. There were no publicly traded equity securities held as of December 31, 2020. Refer to Note 5. Investments in Affiliates for further information regarding Aptiv's equity investments.Use of estimates—Preparation of consolidated financial statements in conformity with U.S. GAAP requires the use of estimates and assumptions that affect amounts reported therein. Generally, matters subject to estimation and judgment include amounts related to accounts receivable realization, inventory obsolescence, asset impairments, useful lives of intangible and fixed assets, deferred tax asset valuation allowances, income taxes, pension benefit plan assumptions, accruals related to litigation, warranty costs, environmental remediation costs, contingent consideration arrangements, worker’s compensation accruals and healthcare accruals. Due to the inherent uncertainty involved in making estimates, including the duration and severity of the impacts of the COVID-19 pandemic and the ongoing global supply chain disruptions, actual results reported in future periods may be based upon amounts that differ from those estimates.Revenue recognition—Revenue is measured based on consideration specified in a contract with a customer. Customer contracts generally are represented by a combination of a current purchase order and a current production schedule issued by the customer. The Company recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer. From time to time, Aptiv enters into pricing agreements with its customers that provide for 70
