Fair value measurements |
Note 6 – Fair value measurements The Company classifies its financial instruments using a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include:
For the three months ended March 31, 2019, the Company has not transferred any assets between fair value measurement levels. Financial assets and liabilities measured at fair value on a recurring basis The Company evaluates financial assets and liabilities subject to fair value measurements on a recurring basis to determine the appropriate level at which to classify them each reporting period. This determination requires the Company to make subjective judgments as to the significance of inputs used in determining fair value and where such inputs lie within the hierarchy. As part of the Company’s bridge financing and amendment to the MGHIF Note, the Company issued stock purchase warrants that the Company considers to be mark-to-market liabilities due to certain put features that allow the holder to put the warrant back to the Company for cash equal to the Black-Scholes value of the warrant upon a change of control or fundamental transaction. The Company determines the fair value of the warrant liabilities using the Black-Scholes option pricing model. Using this model, level 3 unobservable inputs include the estimated volatility of the Company’s common stock, estimated terms of the instruments, and estimated risk-free interest rates. The following table sets forth a summary of changes in the fair value of level 3 liabilities measured at fair value on a recurring basis for the three months ended March 31, 2019:
Financial assets and liabilities carried at fair value on a non-recurring basis The Company does not have any financial assets and liabilities measured at fair value on a non-recurring basis. Non-financial assets and liabilities carried at fair value on a recurring basis The Company does not have any non-financial assets and liabilities measured at fair value on a recurring basis. Non-financial assets and liabilities carried at fair value on a non-recurring basis The Company measures its long-lived assets, including property and equipment and intangible assets (including goodwill), at fair value on a non-recurring basis when they are deemed to be impaired. No such fair value impairment was recognized in the three months ended March 31, 2019 and 2018. |
