Securities Purchase Agreement and Warrant Issuances	Securities Purchase Agreement and Warrant Issuances On September 3, 2014, the Company entered into a purchase agreement (the “Purchase Agreement”) with HC2 Holdings 2, Inc., a Delaware corporation (the “Investor”), pursuant to which, on September 8, 2014, the Company sold to the Investor (i) 7,363,334 shares of the Company’s common stock, par value $0.001 per share, (ii) a warrant to purchase 4,117,647 shares of the Company's common stock at an exercise price of $2.26 per share (the “2014 Warrant”) and (iii) 87,196 shares of the Company’s Series C Convertible Preferred Stock, par value $0.001 per share (the “Series C Preferred Stock”), all at a purchase price of (a) $1.75 per share of common stock plus, in each case, the related 2014 Warrant and (b) $17.50 per share of Series C Preferred Stock, for aggregate gross proceeds of approximately $14.4 million. Due to insufficient authorized shares to satisfy the exercise of the instrument in full at the time of issuance, the Company determined that the instrument should be treated as a derivative instrument as of September 30, 2014. Liability classification was required because share settlement was not within the control of the Company and the 2014 Warrant was not considered to be “indexed to the company’s own stock” and therefore did not qualify for the exemptions provided by ASC 815. Because the 2014 Warrant had no comparable market data to determine fair value, the Company hired an independent valuation firm to assist with the valuation of the 2014 Warrant at the measurement date and as of September 30, 2014. The primary factors used to determine the fair value included: (i) the fair value of the Company’s common stock; (ii) the volatility of the Company’s common stock; (iii) the risk free interest rate; (iv) the estimated likelihood and timing of exercise; and (v) the estimated likelihood and timing of a future financing arrangement. Increases in the market value of the Company’s common stock and volatility, which have the most impact on the fair value of the 2014 Warrant, would cause the fair value of the 2014 Warrant to change. While classified as a liability, the 2014 Warrant was measured at fair value on a recurring basis and any unrealized losses were recognized in earnings as other expense. During the three months ended September 30, 2014, the Company recorded a change in fair value of $4.8 million related to the 2014 Warrant, primarily as a result of an increase in the market value of the Company’s common stock. On November 17, 2014, at a Special Meeting of the Stockholders, the Company received stockholder approval to increase the number of authorized shares of the Company's common stock. With this approval, the Company had a sufficient amount of authorized shares to satisfy the exercise of the instrument in full. As a result, the Company marked the 2014 Warrant to fair value and then reclassified it to additional paid-in-capital. On March 26, 2015, the Investor exercised a portion of the 2014 Warrant to purchase 3,824,600 shares of the Company's common stock at an exercise price of $2.26 per share for total proceeds of $8.6 million. On March 26, 2015, in order to induce the Investor to exercise the 2014 Warrant for cash in connection with the acquisition of FW, the Company issued to the Investor a new warrant (the “2015 Warrant”) to purchase 1,593,583 shares of the Company's common stock at an exercise price of $5.50 per share. The 2015 Warrant will be exercisable into shares of the Company's common stock during the period commencing on September 26, 2015 and ending on March 26, 2020, the expiration date of the 2015 Warrant. The 2015 Warrant will generally only be exercisable on a cash basis; provided, however, that the 2015 Warrant may be exercised on a cashless basis if and only if a registration statement relating to the issuance of the shares underlying the 2015 Warrant is not then effective or an exemption from registration is not available for the resale of such shares. The 2015 Warrant may be exercised by surrendering to the Company the certificate evidencing the 2015 Warrant to be exercised with the accompanying exercise notice, appropriately completed, duly signed and delivered, together with cash payment of the exercise price, if applicable. The Company reviewed the terms of the 2015 Warrant to determine whether or not it met the criteria of a derivative instrument under Accounting Standards Codification (“ASC”) 815, Derivatives and Hedges. Pursuant to this guidance, the Company has determined that the 2015 Warrant does not require liability accounting and has classified the warrant as equity. Because the 2015 Warrant has no comparable market data to determine fair value, the Company hired an independent valuation firm to assist with the valuation of the 2015 Warrant at March, 26, 2015, the issuance date of the warrant. The primary factors used to determine the fair value include: (i) the fair value of the Company’s common stock; (ii) the volatility of the Company’s common stock; (iii) the risk free interest rate and (iv) the estimated likelihood and timing of exercise. The 2015 Warrant was issued in connection with the cash exercise of the 2014 Warrant, and accordingly, the fair value of the 2015 Warrant of $3.5 million was considered cost of capital and netted against the $8.6 million aggregate proceeds received from the exercise of the 2014 Warrant.
