Fair Value Measurements Fair Value Measurements
The Company’s only financial instrument measured at fair value on a recurring basis is its interest make-whole payment derivative liability on its 2025 Notes (see Note 4 – Debt). The fair value of that liability was zero as of both March 31, 2024 and December 31, 2023.
The fair value of the interest make-whole payment derivative liability was determined using a Monte Carlo model using the following key assumptions:

There was no change in the fair value of the interest make-whole liability for the three months ended March 31, 2024 or March 31, 2023.

Other Financial Instruments
The carrying values of the Company’s other financial assets and liabilities approximate their fair values because of their short-term nature, with the exception of the 2025 Notes. The 2025 Notes are carried at amortized cost, adjusted for changes in the fair value of the embedded derivative.
