Fair Value Measurements | 4. Fair Value Measurements Interest Rate Risk Management and Derivative Instruments ​ In April 2020, we entered into interest rate swap agreements to reduce our exposure to variable interest rates on our revolving credit facility. The interest rate swap agreements terminated on September 30, 2022. ​ At times, we use derivative instruments to manage exposure to market risk, including interest rate risk. Unsettled amounts under our interest rate swaps, if any, are recorded in the Consolidated Balance Sheet at fair value in “Other Receivables” or “Other Current Liabilities.” Gains and losses on our interest rate swaps are recorded in the Consolidated Income Statement in “Interest Expense.” For the years ended December 31, 2022, 2021 and 2020, we recognized a net gain of $0.3 million, a net loss of $0.5 million and a net loss of $0.3 million, respectively, related to our interest rate swaps. We currently do not have any derivatives that are accounted for as hedges under ASC 815. ​ Fair Value Measurement ​ We classify and disclose assets and liabilities carried at fair value in one of the following three categories:
| ● | Level 1—quoted prices in active markets for identical assets and liabilities;
| ● | Level 2—observable market-based inputs or unobservable inputs that are corroborated by market data; and
| ● | Level 3—significant unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.
The following table summarizes the fair values, and levels within the fair value hierarchy in which the fair value measurements are included, for assets and liabilities measured on a recurring basis as of December 31, 2022 and 2021 (in thousands):

​ Cash and cash equivalents consist primarily of highly rated money market funds at a variety of well-known institutions with original maturities of three months or less. The original cost of these assets approximates fair value due to their short-term maturity. We believe the carrying value of our debt associated with our revolving credit facility approximates its fair value due to the variable rate on such debt. We believe the carrying values of our notes to former owners approximate their fair values due to the relatively short remaining terms on these notes. We have life insurance policies covering 120 employees with a combined face value of $82.1 million. The policies are invested in several investment vehicles, and the fair value measurement of the cash surrender balance associated with these policies is determined using Level 2 inputs within the fair value hierarchy and will vary with investment performance. The cash surrender value of these policies is included in “Other Noncurrent Assets” in our Consolidated Balance Sheets. We value contingent earn-out obligations using a probability weighted discounted cash flow method. This fair value measurement is based on significant unobservable inputs in the market and thus represents a Level 3 measurement within the fair value hierarchy. This analysis reflects the contractual terms of the purchase agreements (e.g., minimum and maximum payments, length of earn-out periods, manner of calculating any amounts due, etc.) and utilizes assumptions with regard to future cash flows and operating income, probabilities of achieving such future cash flows and operating income and a weighted average cost of capital. Significant changes in any of these assumptions could result in a significantly higher or lower potential liability. The contingent earn-out obligations are measured at fair value each reporting period, and changes in estimates of fair value are recognized in earnings. As of December 31, 2022, cash flows were discounted using a weighted average cost of capital ranging from 11.0% - 17.0%. The table below presents a reconciliation of the fair value of our contingent earn-out obligations that use significant unobservable inputs (Level 3) (in thousands):

​ We measure certain assets at fair value on a nonrecurring basis. These assets are recognized at fair value when they are concluded to be other-than-temporarily impaired. No goodwill or other intangible asset impairments were recorded during the years ended December 31, 2022, 2021 and 2020. We did not recognize any other impairments on those assets required to be measured at fair value on a nonrecurring basis. See Note 6 “Goodwill and Identifiable Intangible Assets, Net” for further discussion.
