4. Fair Value Measurements

In accordance with ASC 820, Fair Value Measurements and Disclosures, the Company generally defines fair value 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). The Company uses a three-tier fair value hierarchy, which classifies the inputs used in measuring fair values. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements), and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below:

 

 

Level 1 – inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

 

 

Level 2 – inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. If the asset or liability has a specified (contractual) term, a Level 2 input must be observable for substantially the full term of the asset or liability.

 

 

Level 3 – inputs are unobservable inputs for the asset or liability in which there is little, if any, market activity for the asset or liability at the measurement date.

The Company’s cash equivalents primarily consist of money market deposits which total approximately $53.3 million at March 31, 2020 and are valued based on Level 1 of the fair value hierarchy. As described in Note 8 “Debt”, during 2019, the Company granted warrants to purchase 19,790 shares of common stock in connection with an amendment to its financing arrangement. These equity-classified warrants were valued using the Black-Scholes pricing model, which falls within Level 3 of the fair value hierarchy.

The assumptions used in the Black-Scholes pricing model were as follows at the date of grant:
