6. Warrant Liability
We currently have outstanding warrants to purchase an aggregate of 983,395 shares of common stock (“Series A Warrants”). The Series A Warrants are exercisable at $4.85 per share (reflecting an adjustment arising from the issuance of warrants described in Note 8 below) and expire in April 2018. The Series A Warrants contain a provision where the warrant holder has the option to receive cash, equal to the Black Scholes fair value of the remaining unexercised portion of the warrant, as cash settlement in the event that there is a fundamental transaction (contractually defined to include various merger, acquisition or stock transfer activities). Due to this provision, ASC 480, Distinguishing Liabilities from Equity requires that these warrants be classified as liabilities. The fair values of these warrants have been determined using the Lattice valuation model, and the changes in the fair value are recorded in the Condensed Statements of Operations and Comprehensive Loss. The Lattice model provides for assumptions regarding volatility and risk-free interest rates within the total period to maturity.
The key assumptions used to value the Series A Warrants were as follows:
