Our derivative instruments within the scope of Accounting Standards Codification ("ASC") 815, Derivatives and Hedging, are required to be recorded at fair value. Our derivative instruments that are recorded at fair value include interest rate swaps and foreign currency forward contracts. See Note 10 to these consolidated financial statements for additional information about our derivative instruments. The fair value of our interest rate swaps and foreign currency forward contracts are based on model-driven valuations using Secured Overnight Financing Rate ("SOFR") rates and foreign currency forward rates, respectively, which are observable at commonly quoted intervals. Accordingly, our interest rate swaps and foreign currency forward contracts are classified within Level 2 of the fair value hierarchy. Our financial contracts that were indexed to LIBOR were modified to reference SOFR during the three months ended September 30, 2022. These modifications did not have a significant financial impact. Contingent consideration obligations arise from business acquisitions. The fair values are based on discounted cash flow analyses reflecting a probability-weighted assessment approach derived from the likelihood of possible achievement of specified performance measures or events and captures the contractual nature of the contingencies, commercial risk, and the time value of money. As the fair value measurements for our contingent consideration obligations contain significant unobservable inputs, they are classified within Level 3 of the fair value hierarchy. See Note 3 to these consolidated financial statements for additional information about our contingent consideration obligations. We believe the carrying amounts of our cash and cash equivalents, restricted cash, accounts receivable, trade accounts payable, accrued expenses and other current liabilities and due to customers approximate their fair values at December 31, 2023 and December 31, 2022, due to the immediate or short-term maturity of these instruments. We believe the carrying amount of our debt approximates its fair value at December 31, 2023 and December 31, 2022, as the debt bears interest rates that approximate market value. As SOFR rates are observable at commonly quoted intervals, our debt under the 2020 Credit Facility (as defined below) is classified within Level 2 of the fair value hierarchy. The fair value of our fixed rate debt does not exceed the carrying amount. We did not transfer any assets or liabilities among the levels within the fair value hierarchy during the years ended December 31, 2023, 2022 and 2021. Non-recurring fair value measurements Assets and liabilities that are measured at fair value on a non-recurring basis include long-lived assets, intangible assets, goodwill and operating lease ROU assets. These assets are recognized at fair value during the period in which an acquisition is completed or at lease commencement, from updated estimates and assumptions during the measurement period, or when they are considered to be impaired. These non-recurring fair value measurements, primarily for long-lived assets, intangible assets acquired and operating lease ROU assets, are based on Level 3 unobservable inputs. In the event of an impairment, we determine the fair value of these assets other than goodwill using a discounted cash flow approach, which contains significant unobservable inputs and, therefore, is considered a Level 3 fair value measurement. The unobservable inputs in the analysis generally include future cash flow projections and a discount rate. For goodwill impairment testing, we estimate fair value using market-based methods including the use of market capitalization and consideration of a control premium. During the year ended December 31, 2023, we recorded noncash impairment charges of $5.6 million against certain operating lease ROU assets and $1.1 million impairment charges against certain property and equipment assets. See Notes 11 and 7, respectively, to these consolidated financial statements for additional details. During the year ended December 31, 2022, we recorded noncash impairment charges of $2.3 million against certain previously capitalized software development costs, $2.0 million against certain insignificant customer relationship intangible assets that were held for sale, $1.0 million against certain operating lease ROU assets and insignificant impairment charges against certain property and equipment assets. See Notes 11 and 7, respectively, to these consolidated financial statements for additional details. During the year ended December 31, 2021, we recorded noncash impairment charges of $3.6 million against certain operating lease ROU assets and $1.7 million against certain property and equipment assets. See Notes 11 and 7, respectively, to these consolidated financial statements for additional details. There were no other non-recurring fair value adjustments during 2023, 2022 and 2021 except for certain business combination accounting adjustments to the initial fair value estimates of the assets acquired and liabilities assumed at the acquisition date from updated estimates and assumptions during the measurement period. See Note 3 to these consolidated financial statements for additional details.
