FAIR VALUE MEASUREMENTS
Fair value is defined 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 measurements are classified using a three-level hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement. The hierarchy gives the highest priority to observable inputs such as unadjusted quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The Company uses observable inputs where relevant and whenever possible. The three levels of the hierarchy are defined as follows:
Level 1 — Fair value is derived using quoted prices from active markets for identical instruments.
Level 2 — Fair value is derived using quoted prices for similar instruments from active markets or for identical or similar instruments in markets that are not active; or, fair value is based on model-derived valuations in which all significant inputs and significant value drivers are observable from active markets.
Level 3 — Fair value is derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.
The carrying value of cash and cash equivalents, restricted cash, accounts receivable, and accounts payable and accrued expenses approximates their fair value because of their short-term nature.
Long-term Debt — The Company’s term loan B is recorded at adjusted cost, net of original issue discounts and deferred financing costs. The fair value of the Company’s term loan B is based on current bid prices or prices for similar instruments from active markets and is classified as Level 2. The Company's revolving credit facility is recorded at cost and its fair value is classified as Level 2. As of December 31, 2025 and 2024, the estimated fair value approximated the carrying value of long-term debt.
Derivative Financial Instruments — The Company’s derivative financial instruments, comprised of interest rate cap agreements, are recorded at fair value and estimated using market-standard valuation models. Such models project future cash flows and discount the future amounts to a present value using market-based observable inputs. Additionally, the fair value of the interest rate caps included consideration of credit risk. The Company used a potential future exposure model to estimate this credit valuation adjustment (“CVA”). The inputs to the CVA were largely based on observable market data, with the exception of certain assumptions regarding credit worthiness. As the magnitude of the CVA was not a significant component of the fair value of the interest rate caps, it was not considered a significant input. The fair value of the interest rate caps is classified as Level 2. As of December 31, 2025, the fair value of the interest rate cap agreements was $2.2 million, of which $1.8 million was recorded in prepaid expenses and other current assets and $0.4 million was recorded in other assets on the consolidated balance sheet. As of December 31, 2024, the fair value of the interest rate cap agreements was $14.7 million, of which $8.4 million was recorded in prepaid expenses and other current assets and $6.3 million was recorded in other assets on the consolidated balance sheet.
Debt Securities — The Company’s investments in debt securities, which are classified as available-for-sale, primarily consist of U.S. Treasury and U.S. government agency securities, corporate bonds and certificates of deposits. These securities are held in escrow by the Company’s wholly-owned captive insurance company and were purchased with restricted cash. As such, these securities are not available to fund the Company’s operations. Debt securities are recorded at fair value. As of December 31, 2025, the fair value of the available-for-sale debt securities was $39.5 million and was classified based on the instruments’ maturity dates, with $15.4 million included in prepaid expenses and other current assets and $24.1 million in other assets on the consolidated balance sheet. As of December 31, 2024, the fair value of the available-for-sale debt securities was $33.7 million and was classified based on the instruments’ maturity dates, with $11.7 million included in prepaid expenses and other current assets and $22.0 million in other assets on the consolidated balance sheet. As of December 31, 2025, debt securities classified as Level 1 and Level 2 had a fair value of $30.9 million and $8.6 million, respectively.
At December 31, 2025 and 2024, the amortized cost was $39.3 million and $33.7 million, respectively. The debt securities held at December 31, 2025 had remaining contractual maturities ranging from less than one year to approximately six years. Unrealized gains and losses, net of tax, and realized gains and losses, on available-for-sale debt securities were immaterial for the years ended December 31, 2025, 2024 and 2023.
Nonrecurring Fair Value Estimates — During the years ended December 31, 2025, 2024, and 2023, the Company recognized impairment losses of $47.5 million, $33.9 million, and $35.9 million, respectively, primarily related to fixed assets and operating lease right-of-use assets.
The estimated fair value of the applicable long-lived assets was based on the fair value of the asset groups, calculated using a discounted cash flow model, with unobservable inputs. The fair value of the fixed assets was insignificant given the current and expected cash flows for the related centers and the valuation of the lease right-of-use-assets considered the amount a market participant would pay for use of the asset. The Company classified the long-lived assets as a Level 3 fair value measurement due to the lack of observable inputs used in the model.
