The change in fair values of the warrant liabilities is recorded in other income (expense) in the consolidated statement of operations.
The key inputs into the Black-Scholes option pricing model are the current
per-share
value and the expected volatility of the Company’s common stock. Significant changes in these inputs will directly increase or decrease the estimated fair value of the Company’s warrant liabilities.
