Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	8. DERIVATIVES The Company has identified various embedded derivatives resulting from certain features in the Company’s borrowing arrangements, requiring recognition on its consolidated balance sheets. None of these derivative instruments are designated as a hedge. Derivative liabilities are recorded in "Other non-current liabilities" or "Intangible and other assets" on the Company's consolidated balance sheet. The fair value of each embedded derivative is marked-to-market at the end of each reporting period, or more frequently as deemed necessary, with any changes in value reported in the consolidated statements of operations and consolidated statements of cash flows as a non-cash operating activity. The instruments and related features embedded in the debt instruments that are required to be accounted for as derivatives are described below. See Note 9: Fair Value Measurements for further discussion. Embedded Derivatives within the 2023 Funding Agreement The 2023 Funding Agreement contains certain prepayment features that are required to be bifurcated and recorded as an embedded derivative on the Company's consolidated balance sheet with a corresponding debt discount or premium that is netted against the principal amount of the draws under the 2023 Funding Agreement. As the Company makes a draw on the 2023 Funding Agreement, an associated embedded derivative is bifurcated and recorded. The Company determines the fair value of the embedded derivatives using a discounted cash flow model. As the discount yield and the effective interest rate of the loan fluctuates based on projected cash flows, the derivative may result in either a liability or an asset to the Company. During the year ended December 31, 2023, the Company recorded a derivative gain of $1.6 million, which is reflected in "Derivative gain (loss) and other" in the Company’s consolidated statement of operations. As of December 31, 2023, the fair value of the embedded derivatives within the 2023 Funding Agreement were assets totaling $1.3 million. Compound Embedded Derivative within the 2019 Facility Agreement The 2019 Facility Agreement contained certain contingently exercisable put features that were required to be bifurcated and recorded as a compound embedded derivative. The Company determined the fair value of this derivative using a probability weighted discounted cash flow model. During the years ended December 31, 2022 and 2021, the Company recorded derivative losses of $1.0 million and gains of $0.2 million, respectively, which is reflected in Derivative gain (loss) and other in the Company’s consolidated statement of operations. As of December 31, 2022, the fair value of the compound embedded derivative within the 2019 Facility Agreement was $0.1 million. In November 2022, the Company exchanged a portion of the 2019 Facility Agreement into Series A Preferred Stock. In March 2023, the Company refinanced the remaining principal outstanding under the 2019 Facility Agreement with proceeds from the issuance of its 2023 13% Notes. As a result of this activity, the Company wrote off the embedded derivative associated with the 2019 Facility Agreement, which is included in "(Loss) gain on extinguishment of debt" on the consolidated statement of operations; therefore, no balance remained as of December 31, 2023. See Note 6: Long-Term Debt and Other Financing Arrangements for further discussion. Compound Embedded Derivative within the 2013 8.00% Notes The 2013 8.00% Notes contained a conversion option and contingent put feature that were required to be bifurcated and recorded as a compound embedded derivative. The Company determined the fair value of the compound embedded derivative liability using a Monte Carlo simulation model. During the years ended December 31, 2022 and 2021, the Company recorded derivative gains of $0.2 million and losses of $1.2 million, respectively, which is reflected in "Derivative gain (loss) and other" in the Company’s consolidated statement of operations. During 2022, the compound embedded derivative with the 2013 8.00% Notes was extinguished; therefore no balance remained as of December 31, 2022.
