Investments

See Note 5 for additional information related to the Company's investments.

The valuation of the Company's investments in debt securities is considered a "Level 2" valuation because the Company has access to quoted prices for identical or comparable securities, but does not have visibility into the volume and frequency of trading for this investment. A market approach is used for recurring fair value measurements and the valuation techniques use inputs that are observable, or can be corroborated by observable data, in an active marketplace.

Investments in private companies measured using Level 3 inputs

The Company's investments measured using Level 3 inputs primarily consist of investments in privately-held companies. Fair values of privately-held securities are estimated using a variety of valuation methodologies, including both market and income approaches. The Company uses valuation techniques appropriate for the type of investment and the information available about the investee as of the valuation date to determine fair value. Recent financing transactions in the investee are generally considered the best indication of the enterprise value and therefore used as a basis to estimate fair value. However, based on a number of factors, such as the proximity in timing to the valuation date or the volume or other terms of these financing transactions, the Company may also use other valuation techniques to supplement this data, including the income approach. When a financing transaction occurs and represents fair value, the Company also uses the calibration process, as appropriate, when estimating fair value on subsequent measurement dates. Calibration is the process of using observed transactions in the investee company's own instruments to ensure that the valuation techniques that will be employed to value the investee company investment on subsequent measurement dates begin with assumptions that are consistent with the original observed transaction as well as any more recent observed transactions in the instruments issued by the investee company.

As of June 30, 2023 and 2022, the Company evaluated its investment in Yanolja for impairment using a combination of the market approach and the income approach in estimating the fair value of the investment as of those dates, and recognized impairment charges. The market approach estimates value using prices and other relevant information generated by market transactions involving comparable companies. The income approach estimates value based on the expectation of future cash flows that a company will generate. These future cash flows are discounted to their present values using a discount rate based on a company's weighted-average cost of capital adjusted to reflect the risks inherent in its cash flows. The key unobservable inputs and ranges used for the June 2023 impairment evaluation, primarily using the income approach, include the weighted average cost of capital (10.5%-14.5%) and the terminal EBITDA multiple (14x-16x). The key unobservable inputs and ranges used for the June 2022 impairment evaluation include, for the market approach, percentage decrease in the calibrated EBITDA multiple (36%) and for the income approach, the weighted average cost of capital (10%-14%) and the terminal EBITDA multiple (14x-16x). Significant changes in any of these inputs in isolation would result in significantly different fair value measurements. A change in the assumption used for EBITDA multiples would result in a directionally similar change in the fair value, and a change in the assumption used for weighted average cost of capital would result in a directionally opposite change in the fair value.

The determination of the fair values of investments, where the Company is a minority shareholder and has access to limited information from the investee, reflects numerous assumptions that are subject to various risks and uncertainties, including key assumptions regarding the investee's expected growth rates and operating margin, as well as other key assumptions with respect to matters outside of the Company's control, such as discount rates and market comparables. It requires significant judgments and estimates and actual results could be materially different than those judgments and estimates utilized in the fair value estimate. Future events and changing market conditions may lead the Company to re-evaluate the assumptions reflected in the valuation which may result in a need to recognize additional impairment charges.

Derivatives

In the normal course of business, the Company is exposed to the impact of foreign currency fluctuations. The Company mitigates these risks by following established risk management policies and procedures, including the use of derivatives. The Company enters into foreign currency forward contracts to hedge its exposure to the impact of movements in foreign currency exchange rates on its transactional balances denominated in currencies other than the functional currency. The Company does not use derivatives for trading or speculative purposes.

The Company's derivative instruments are valued using pricing models. Pricing models take into account the contract terms as well as multiple inputs where applicable, such as interest rate yield curves, option volatility, and foreign currency exchange rates. The valuation of derivatives is considered "Level 2" fair value measurement. The Company's derivative instruments are typically short-term in nature. The Company reports the fair values of its derivative assets and liabilities on a gross basis in the Consolidated Balance Sheets in "Other current assets" and "Accrued expenses and other current liabilities," respectively.

As of December 31, 2023 and 2022, the Company did not designate any derivatives as hedges for accounting purposes. Gains and losses resulting from changes in the fair values of derivative instruments are recognized in "Other income (expense), net" in the Consolidated Statements of Operations in the period that the changes occur and cash flow impacts, if any, are classified within "Net cash provided by operating activities" or "Net cash used in financing activities," as appropriate, in the Consolidated Statements of Cash Flows.

The table below provides estimated fair values and notional amounts of foreign currency exchange derivatives outstanding at December 31, 2023 and 2022 (in millions). The notional amount of a foreign currency forward contract is the contracted amount of foreign currency to be exchanged and is not recorded in the balance sheet.


	December 31,
	2023		2022
Estimated fair value of derivative assets	$	62	$	65
Estimated fair value of derivative liabilities	36		26

Notional amount:
Foreign currency purchases	$	4,907	$	2,870
Foreign currency sales	4,200		2,682

The effect of foreign currency exchange derivatives recorded in "Other income (expense), net" in the Consolidated Statements of Operations for the years ended December 31, 2023, 2022, and 2021 is as follows (in millions):


	Year Ended December 31,
	2023		2022		2021
Losses on foreign currency exchange derivatives	$	106	$	52	$	30

Derivatives designated as cash flow hedges

In March 2021, the Company entered into reverse treasury lock agreements with certain financial institutions, with an aggregate notional amount of $1.8 billion and expiration date of March 31, 2021, to hedge the risk of changes in the cash flows related to the planned redemption, in April 2021, of the Senior Notes due April 2025 (the "April 2025 Notes") and the Senior Notes due April 2027 (the "April 2027 Notes") attributable to changes in the underlying U.S. treasury notes' interest rates. The Company designated the reverse treasury lock agreements as cash flow hedges. As of March 31, 2021, the Company recognized unrealized losses of $15 million in "Accumulated other comprehensive loss" in the Consolidated Balance Sheet. In April 2021, the Company settled the reverse treasury lock agreements for an aggregate amount of $15 million and also redeemed the April 2025 Notes and the April 2027 Notes. The cash flows related to the reverse treasury lock agreements are classified within "Net cash used in financing activities" in the Consolidated Statement of Cash Flows. During the three months ended June 30, 2021, the Company reclassified the losses on the cash flow hedges from "Accumulated other comprehensive loss" in the Consolidated Balance Sheet to "Other income (expense), net" in the Consolidated Statement of Operations, concurrently with the recognition of the losses upon early extinguishment of the April 2025 Notes and the April 2027 Notes (see Note 12).

Other Financial Assets and Liabilities

At December 31, 2023 and 2022, the Company's cash consisted of bank deposits. Cash equivalents principally include money market fund investments and certificates of deposit and their carrying value generally approximates the fair value as they are readily convertible to known amounts of cash. Other financial assets and liabilities, including restricted cash, accounts payable, accrued expenses, and deferred merchant bookings, are carried at cost which approximates their fair values because of the short-term nature of these items. Accounts receivable and other financial assets measured at amortized cost are carried at cost less an allowance for expected credit losses to present the net amount expected to be collected (see Note 7). See Note 12 for the estimated fair value of the Company's outstanding senior notes, including the estimated fair value of the Company's convertible senior notes.
