The fair value of the Company’s Convertible Notes was $187.9 million as of September 30, 2019. The estimated fair value of Convertible Notes was determined based on a discounted cash flow analysis and a binomial lattice model. The valuation required the use of Level 3 unobservable inputs and subjective assumptions, including but not limited to the stock price volatility and bond yield. The use of alternative market assumptions and estimation methodologies could have had an effect on these estimates of fair value.
