Schedule of carrying value and fair value of the Company's convertible subordinated notes
The following table presents the carrying value and fair value of the Company’s convertible notes. The fair value of the Company’s 2029 Convertible Senior Notes was based on Level 1 inputs. In estimating the fair value of its 2024 Convertible Senior Notes and Convertible Unsecured Note, the Company utilized Level 3 inputs including prevailing market interest rates to estimate the debt portion of the instrument and a Black Scholes valuation model to estimate the fair value of the conversion option. The Black Scholes model utilizes the market price of the Company’s common stock, estimates of the stock’s volatility and the prevailing risk-free interest rate in calculating the fair value estimate.
