Fair Value Measurement

6 Months Ended

Jun. 30, 2022

Fair value is defined as the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value maximize the use of observable inputs and minimize the use of unobservable inputs. The fair value hierarchy defines a three-level valuation hierarchy for classification and disclosure of fair value measurements as follows:

Level 1 – Quoted prices in active markets for identical assets or liabilities.

Level 2 – Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

There has been no movement between Level 1 and Level 2 or between Level 2 and Level 3 from December 31, 2021 to June 30, 2022. Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

Debt Derivative Liabilities

The Debt Derivative Liabilities are measured using a ‘with and without’ valuation model to compare the fair value of the Company's financing agreement with Oberland Capital including the identified embedded derivative features and the fair value of a plain vanilla note with the same terms. The fair value of the Oberland Facility including the embedded derivative features was determined using a probability-weighted expected return model based on four potential settlement scenarios for the Oberland Facility due to (a) a 5% probability of a mandatory prepayment event of the Oberland Facility on December 31, 2023; (b) a 15% probability of a mandatory prepayment event of the Oberland Facility on March 31, 2026; (c) a 5% probability of the prepayment of the Oberland Facility at the Company’s option on December 31, 2025; and (d) a 75% probability that the Oberland Facility will be held to its scheduled maturity dates in accordance with the terms of the debt agreement. The estimated settlement value of each scenario, which would include any required make-whole payment, is then discounted to present value

using a discount rate that is derived based on the initial terms of the Oberland Facility at issuance and corroborated utilizing a synthetic credit rating analysis.

The fair value of cash, restricted cash, accounts receivable, accounts payable and accrued expenses approximates the carrying values because of the short-term nature of these instruments. The Oberland Facility is classified as Level 3 within the fair value hierarchy. The carrying value and estimated fair value of the Oberland Facility were $45,263 and $47,759 at June 30, 2022, and $45,325 and $52,605 at December 31, 2021, respectively.
