11. Capitalization and Equity Structure
Summary
The Company’s authorized capital stock at September 30, 2018 consisted of 141,429 shares of common stock and 10,000 shares of preferred stock. At September 30, 2018, 62,617 shares of common stock were issued and outstanding and no shares of preferred stock were issued and outstanding.
Common Stock
On August 21, 2018, the Company entered into a Controlled Equity OfferingSM Sales Agreement ("ATM Agreement") with Cantor Fitzgerald & Co. (the “Agent”) under which the Company may issue and sell shares of its common stock, from time to time, to or through the Agent, by methods deemed to be an “at the market offering.” Shares having an aggregate offering price of up to $25,000 may be offered pursuant to a prospectus dated August 21, 2018 (the “ATM Prospectus”) under the Company’s previously filed and currently effective shelf registration statement on Form S-3 (Registration No. 333-218517). For the three and nine months ended September 30, 2018, the Company sold 1,747 shares of common stock under the ATM Agreement at an average price of $2.48 per share, for aggregate proceeds of $3,961, net of commission and issuance costs, to the Company. As of September 30, 2018, approximately $20,664 aggregate offering price of the Company's common stock remained available for issuance pursuant to the ATM Prospectus.
Warrants
Warrant shares outstanding as of December 31, 2017 and September 30, 2018 were as follows:
Information Agent Warrants
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.
2015 Warrants
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. During the years ended December 31, 2016 and 2017, 488 shares and 30 shares, respectively, of the 2015 warrants, were exercised.
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 September 30, 2018:
