(1)The related unrealized gain (loss) recorded in “Other income (expense), net” was $448 million, $11.6 billion, and $(13.6) billion for the years ended December 31, 2020, 2021, and 2022.

(2)We are required to pledge or otherwise restrict a portion of our cash, cash equivalents, and marketable fixed income securities primarily as collateral for real estate, amounts due to third-party sellers in certain jurisdictions, debt, and standby and trade letters of credit. We classify cash, cash equivalents, and marketable fixed income securities with use restrictions of less than twelve months as “Accounts receivable, net and other” and of twelve months or longer as non-current “Other assets” on our consolidated balance sheets. See “Note 7 — Commitments and Contingencies.”

(3)Our equity investment in Rivian had a fair value of $15.6 billion and $2.9 billion as of December 31, 2021 and December 31, 2022, respectively. The investment was subject to regulatory sales restrictions resulting in a discount for lack of marketability of approximately $800 million as of December 31, 2021, which expired in Q1 2022.
