Fair value measurements Fair value measurements
As of June 30, 2025 and December 31, 2024, the carrying amount of certain financial instruments, including cash and cash equivalents, restricted cash, accounts receivable, accounts payable, and accrued liabilities, were representative of their fair values due to the short-term maturity of these instruments.
The following table presents the fair value hierarchy levels of the Company’s assets and liabilities at fair value:

In accordance with GAAP, the Company has elected to remeasure investments without readily determinable fair values only when an observable transaction occurs for an identical or similar investment of the same issuer. During the three and six months ended June 30, 2025 and 2024, the Company recorded immaterial non-recurring fair value adjustments within Other nonoperating income (expense), net in the condensed consolidated statements of operations and comprehensive income (loss) related to certain other investments without readily determinable fair values.
The Company’s long-term debt is reported at the aggregate principal amount less unamortized deferred financing costs and any above or below market adjustments (as required in purchase accounting) in the condensed consolidated balance sheets. For instruments with no prepayment option, the fair value is estimated utilizing a discounted cash flow model where the contractual cash flows (i.e., coupon and principal repayments) were discounted at a risk-adjusted yield reflective of both the time value of money and the credit risk inherent in each instrument. For instruments that include a prior-to-maturity prepayment option, the fair value is estimated using a Black-Derman-Toy lattice model. The inputs used to estimate the fair value of the Company’s debt instruments are comprised of Level 2 inputs, including risk-free interest rates, credit ratings, and financial metrics for comparable publicly listed companies, and Level 3 inputs, such as risk-adjusted credit spreads based on adjusted yields implied at issuance, and yield volatility (used for instruments with a prepayment option).
