Fair value measurements Fair value measurements
The carrying amount of Cash and cash equivalents, Accounts Receivable, net and Accounts payable is a reasonable approximation of fair value due to the short-term nature of these assets and liabilities. Financial liabilities that are not measured at fair value on a recurring basis include our senior secured term loan and deferred royalty financing obligation. The carrying value of our senior secured term loan approximates fair value as these borrowings are based on variable market rates. The fair value of our deferred royalty obligation was approximately $312.0 million as of both June 30, 2025 and December 31, 2024 and is based on our current estimates of future royalties expected to be paid over the estimated life of the royalty purchase agreement which are level 3 inputs.

The Deerfield warrants were measured at fair value on a recurring basis and were classified as Level 2. The warrants expired on May 19, 2025 in accordance with their terms and therefore, there were no warrants outstanding as of June 30, 2025. As of December 31, 2024 the value of the Deerfield warrants was $0. Fair values were estimated at the end of each reporting period with regard to the Deerfield warrants. The approach to valuation follows the fair value principle, and the key input factors are described for the Deerfield warrants in Note 9, "Deerfield warrants." A Black-Scholes model was used to calculate the fair values.
There were no transfers between the respective levels during the period.
