In September 2017, in connection with the Rights Offering in August 2017, the Company issued warrants to purchase 200 shares of the Company’s common stock with an exercise price of $1.50 per share to an information agent (the “Information Agent Warrants”). The Information Agent Warrants became exercisable immediately upon issuance. These warrants were recorded in stockholders’ equity on the Company’s condensed consolidated balance sheet.

 

In December 2015, the Company issued warrants to purchase 2,122 shares with an exercise price of $3.74 per share (the “2015 Warrants”). The 2015 Warrants contain a put-option provision. Under this provision, while the 2015 Warrants are outstanding, if the Company enters into a Fundamental Transaction, defined as a merger, consolidation or similar transaction, the Company or any successor entity will, at the option of each warrant holder, exercisable at any time within 30 days after the consummation of the Fundamental Transaction, purchase the warrant from the holder exercising such option by paying to the holder an amount of cash equal to the Black-Scholes value of the remaining unexercised portion of such holder’s warrant on the date of the consummation of the Fundamental Transaction. Because of this put-option provision, the 2015 Warrants are classified as a liability and are marked to market at each reporting date.

 

The warrant liability related to the 2015 Warrants is measured at fair value at each reporting date using certain estimated inputs, which are classified within Level 3 of the fair value hierarchy. The following assumptions were used in the Black Scholes Option Pricing Model to measure the fair value of the 2015 warrants as of June 30, 2018:
