Fair Value Disclosures [Abstract] |
Fair Value Measurement of Assets and Liabilities | Fair Value Measurement of Assets and Liabilities Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). A fair value measurement reflects the assumptions market participants would use in pricing an asset or liability based on the best available information. These assumptions include the risk inherent in a particular valuation technique (such as a pricing model) and the risks inherent in the inputs to the model. The Company classifies inputs to measure fair value using a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. The categorization of financial instruments within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The hierarchy is prioritized into three levels (with Level 3 being the lowest) and is defined as follows: Level 1: Pricing inputs are based on quoted market prices for identical assets or liabilities in active markets (e.g., NYSE or NASDAQ). Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis. Level 2: Pricing inputs include benchmark yields, trade data, reported trades and broker dealer quotes, two-sided markets and industry and economic events, yield to maturity, Municipal Securities Rule Making Board reported trades and vendor trading platform data. Level 2 includes those financial instruments that are valued using various pricing services and broker pricing information including Electronic Communication Networks and broker feeds. Level 3: Pricing inputs include significant inputs that are generally less observable from objective sources, including the Company’s own assumptions. The fair market value for level 3 securities may be highly sensitive to the use of unobservable inputs and subjective assumptions. Generally, changes in significant unobservable inputs may result in significantly lower or higher fair value measurements. The Company reviews the fair value hierarchy classification on a quarterly basis. Changes in the observability of valuation inputs may result in a reclassification of levels for certain securities within the fair value hierarchy. There have been no transfers of assets or liabilities between fair value measurement classifications during the three months ended March 31, 2022 or 2021. The following tables summarize the Company’s financial instruments measured at fair value on a recurring basis in accordance with the authoritative guidance for fair value measurements as of March 31, 2022 and December 31, 2021 (in thousands):

The fair value of the interest make-whole payment derivative liability was determined using a Monte Carlo model with the following key assumptions:
| March 31, 2022 |  | December 31, 2021 |  |  |  |
Volatility | 50 | % |  | 50 | % |  |  |  |
Stock price | $4.05 per share |  | $5.83 per share |  |  |  |
Credit spread | 15.53 | % |  | 15.93 | % |  |  |  |
Term | 3.09 years |  | 3.34 years |  |  |  |
Dividend yield | — | % |  | — | % |  |  |  |
Risk-free rate | 2.45 | % |  | 1.02 | % |  |  |  |
The following table sets forth a summary of changes in the fair value of Level 3 liabilities for the three months ended March 31, 2022 (in thousands):

The Company evaluated the 2025 Notes under ASC 815, Derivatives and Hedging, and identified an embedded derivative that required bifurcation. The embedded derivative is an interest make-whole payment. The estimated fair values of the interest make-whole derivative liability at March 31, 2022 and December 31, 2021 were determined using significant assumptions which include an implied credit spread rate for notes with a similar term, the expected volatility and dividend yield of the Company’s common stock and the risk-free interest rate. Changes in the fair value of the interest make-whole payment totaling a gain of $0.6 million for the three months ended March 31, 2022 are included in the Company’s condensed consolidated statement of operations within other income (expense), net. As of March 31, 2022, the embedded derivative had a fair value of $0.3 million. Other Financial Instruments The Company’s financial assets and liabilities are carried at fair value or at amounts that, because of their short-term nature, approximate current fair value, with the exception of the 2025 Notes. On May 12, 2020, the Company issued $180.4 million in aggregate principal amount of 2025 Notes, and restructured its outstanding debt as described further in Note 4. Debt. The Company carries its 2025 Notes at amortized cost adjusted for changes in fair value of the embedded derivative. As of March 31, 2022, $161.9 million in principal amount of the 2025 Notes remain outstanding. It is not practicable to determine the fair value of the 2025 Notes due to the lack of information available to calculate the fair value of such notes.
