FAIR VALUE MEASUREMENTS	12 Months Ended
FAIR VALUE MEASUREMENTS	Dec. 31, 2023
Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS Fair value is defined under U.S. GAAP as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is a market-based measurement that is determined based on assumptions that market participants would use in pricing an asset or a liability. To increase the comparability of fair value measures, the following hierarchy prioritizes the inputs in valuation methodologies used to measure fair value: Level 1 - Measurements that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2 - Measurements that include other inputs that are directly or indirectly observable in the marketplace. Level 3 - Measurements derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. These fair value measurements require significant judgment. In determining fair value, we use various valuation approaches within the fair value measurement framework. The valuation methodologies used for our assets and liabilities measured at fair value and their classification in the valuation hierarchy are summarized below: Fair value option investments and available-for-sale securities. We have fair value option investments and available-for-sale securities that we measure using the income approach. We have classified these investments as Level 3 due to the lack of observable market data over fair value inputs such as cash flow projections and discount rates. There was no activity in the fair value of recurring Level 3 fair value measurements for the years ended December 31, 2023, 2022 and 2021. Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis Certain assets and liabilities are measured at fair value on a nonrecurring basis, including assets that are written down to fair value as a result of an impairment or modified due to an observable price change in an orderly transaction. We recognized a non-cash remeasurement of our investment in SumUp of $25.8 million during the year ended December 31, 2023. During the year ended December 31, 2021, we adjusted the carrying value of SumUp which resulted in an unrealized gain of $89.1 million and sold shares in two other equity investments for a gain of $6.4 million. See Note 5, Investments, for additional information. We recognized $35.4 million in non-cash impairment charges related to goodwill for the year ended December 31, 2022. We recognized $15.3 million in non-cash impairment charges related to long-lived assets for the year ended December 31, 2022, of which $3.0 million are included in Restructuring and related charges on our Consolidated Statements of Operations. We recognized $7.7 million in non-cash impairment charges related to Right-of-use assets - operating leases and leasehold improvements during the year ended December 31, 2021, which is included in Restructuring and related charges on our Consolidated Statements of Operations. See Note 3, Property, Equipment and Software, Net, Note 4, Goodwill and Other Intangible Assets, Note 8, Leases and Note 13, Restructuring and Related Charges, for additional information. Estimated Fair Value of Financial Assets and Liabilities Not Measured at Fair Value Our financial instruments not carried at fair value consist primarily of accounts receivable, restricted cash, short-term borrowings, accounts payable, accrued merchant and supplier payables and accrued expenses. The carrying values of those assets and liabilities approximate their respective fair values as of December 31, 2023 and 2022 due to their short-term nature.
