Fair Value Measurements | NOTE 3. FAIR VALUE MEASUREMENTS The fair value of our financial assets and liabilities measured on a recurring basis is as follows:
Financial Instruments Not Recorded at Fair Value on a Recurring Basis We report our financial instruments at fair value, with the exception of the 0% convertible senior notes, due in January 2023, (the "2023 Notes") and the 2.50% convertible senior notes, due in 2026, (the "2026 Notes") (collectively, the "Notes"). Financial instruments that are not recorded at fair value on a recurring basis are measured at fair value on a quarterly basis for disclosure purposes. The carrying values and estimated fair values of financial instruments not recorded at fair value are as follows:
The carrying value of the 2023 Notes as of July 31, 2020 and April 30, 2021 was net of the unamortized debt discount of $80.3 million and $56.7 million, respectively, and unamortized debt issuance costs of $4.5 million and $3.2 million, respectively. The carrying value of the 2026 Notes as of April 30, 2021 includes $8.9 million of non-cash interest expense that was converted to the principal balance, net of the unamortized debt discount of $211.8 million and unamortized debt issuance costs of $24.2 million. The total estimated fair value of the 2023 Notes was determined based on the closing trading price per $100 of the 2023 Notes as of the last day of trading for the period. We consider the fair value of the 2023 Notes to be a Level 2 valuation due to the limited trading activity. The total estimated fair value of the 2026 Notes is based on a binomial model. We consider the fair value of the 2026 Notes to be a Level 3 valuation, as the 2026 Notes are not publicly traded. The Level 3 inputs used are the same as those used to determine the estimated fair value of the associated derivative liability, as detailed below. Derivative Liability The conversion feature of the 2026 Notes represents an embedded derivative. The 2026 Notes are not considered to be conventional debt and we determined that the embedded conversion feature was required to be bifurcated from the host debt and accounted for as a derivative liability, as the 2026 Notes are convertible into a variable number of shares until the conversion price becomes fixed in September 2021, based on the level of achievement of the associated financial performance metric. As such, the initial fair value of the derivative instrument was recorded as a liability in the condensed consolidated balance sheet with the corresponding amount recorded as a discount to the 2026 Notes upon issuance. The derivative liability is considered a Level 3 valuation and is recorded at its estimated fair value at the end of each reporting period, with the change in fair value recognized within other expense, net in the condensed consolidated statements of operations. The following table shows the estimated fair value of the derivative liability as of the issuance of the 2026 Notes and the change in fair value from issuance through April 30, 2021:
We estimated the fair value of the derivative liability using a binomial model, with the following valuation inputs:
(1) The conversion ratio was estimated based on the latest forecast of the associated financial performance metric. (2) The discount rate was estimated based on the implied rate for the 2023 Notes as well as a credit analysis. |
