[1] As the fair value option was elected for the C-2 Notes, the change in fair value attributable to instrument-specific credit risk associated with each instrument is recorded within Other comprehensive income (loss), and the remaining change in fair value is recorded within Other income (expense), net on the condensed consolidated statements of operations and comprehensive loss. The change in instrument specific credit risk is estimated based on the option adjusted spread of comparable companies and the option adjusted spread of the U.S. high yield index for companies with similar credit ratings.
