Stockholders’ Equity
Stock Warrants
As part of an agreement dated as of July 27, 2010 with Cappello Capital Corp., the placement agent in connection with our best efforts offering and the financial advisor in connection with our completed rights offering, we issued warrants to purchase 250,000 shares of our common stock for services performed. The warrants had an exercise price of $9.60 per share. According to the agreement, the warrants vested on October 14, 2010 and were exercisable until their expiration on October 14, 2015. The Company followed the guidance of FASB ASC Topic 815-40, Derivatives and Hedging—Contracts in Entity’s Own Stock, which established a framework for determining whether certain freestanding and embedded instruments are indexed to a company’s own stock for purposes of evaluation of the accounting for such instruments under existing accounting literature. Under GAAP, the issuer is required to measure the fair value of the equity instruments in the transaction as of the earlier of (i) the date at which a commitment for performance by the counterparty to earn the equity instruments is reached or (ii) the date at which the counterparty’s performance is complete. The fair value of the warrants at the date of issuance totaling $2.0 million was recorded as a liability and a cost of equity, which was determined by the Black-Scholes option pricing model. The expected stock volatility was based on historical volatility of our common stock over the expected term of the warrants. We used a weighted average expected stock volatility of 111.46 percent. The expected life assumption was based on the contract term of five years. The dividend yield of zero was based on the fact that we had no intention to pay cash dividends for the term at the grant date. The risk free rate of 2.07 percent used for the warrants was equal to the zero coupon rate in effect at the time of the grant. During the years of 2012, 2013 and 2014, all the stock warrants were exercised and there were no outstanding stock warrants as of December 31, 2014.
