Preferred Stock	Preferred Stock Our Certificate of Incorporation authorizes the issuance of up to 5,000,000 shares of preferred stock. As of December 31, 2014, there were: 100 shares of Series B-1 Preferred Stock authorized, and no shares issued or outstanding; 7,500 shares of Series A-2 Preferred Stock authorized and 53 shares issued and outstanding; and 4,000 shares of Series D Preferred Stock authorized and no shares issued or outstanding. During the year ended December 31, 2013, the Company exchanged all 100 issued and outstanding shares of Series B-1 Preferred Stock pursuant to exchange agreements between the Company and the holders of this preferred stock (the “Exchange Agreements”) for 6,667,286 shares of the Company’s common stock. The liquidation preference for the Preferred Shares was approximately $10,247,000, representing an effective conversion price for the Company’s common stock issued pursuant to the Exchange Agreements of $1.54 per share. In connection with the Exchange Agreements, the holders of the Preferred Shares waived their claim to accrued dividends on the Preferred Shares in the approximate amount of $247,000. The Company recorded the reversal of these accrued dividends as a reduction to Preferred Stock Dividends on the accompanying consolidated statement of operations. During the years ended December 31, 2014 and 2013, the Company incurred approximately $5,000 and $289,000 of costs in connection with the Exchange Agreements, respectively, which were recorded as a reduction to additional paid-in capital. The Company also issued 100,000 of shares of Common Stock to a broker in October 2013, recorded in stockholders’ equity as a cost of the preferred stock exchange equal to a value of $135,000. This value was based on the October 15, 2013 stock price of $1.35 (see Note 20 for further discussion). The Exchange Agreements were recorded through stockholders’ equity. Each share of Series A-2 Preferred Stock has a stated value of $7,500 per share (the “A-2 Stated Value”), a liquidation preference equal to the Series A-2 Stated Value, and is convertible at the holder’s election into common stock at a conversion price per share of $2.9844 as of December 31, 2014. Therefore, each share of Series A-2 Preferred Stock is convertible into 2,500 shares of common stock as of December 31, 2014. The conversion price is subject to adjustment upon the occurrence of certain events set forth in our Certificate of Incorporation. During the year ended December 31, 2014, the conversion price was adjusted from $3.00 per share to $2.9844 per share as a result of sales in the ATM Offering during this period. The Series A-2 Preferred Stock is subordinate to the Series B-1 Preferred Stock but senior to all other classes of equity, has weighted average anti-dilution protection and, commencing on January 1, 2013, is entitled to cumulative dividends at a rate of 5% per annum, payable quarterly, based on the Series A-2 Stated Value. All dividends are payable at the option of the holder in cash or through the issuance of a number of additional shares of Series A-2 Preferred Stock with an aggregate liquidation preference equal to the dividend amount payable on the applicable dividend payment date. As of December 31, 2014 and 2013, the Company has recorded $40,000 and $20,000, respectively, in accrued dividends on the accompanying balance sheet related to the Series A-2 Preferred Stock. In accordance with ASC Topic 815, we evaluated whether our convertible preferred stock contains provisions that protect holders from declines in our stock price or otherwise could result in modification of the exercise price and/or shares to be issued under the respective preferred stock agreements based on a variable that is not an input to the fair value of a “fixed-for-fixed” option and require a derivative liability. The Company determined no derivative liability is required under ASC Topic 815 with respect to our convertible preferred stock. A contingent beneficial conversion amount is required to be calculated and recognized when and if the adjusted $3.00 conversion price of the convertible preferred stock is adjusted to reflect a down round stock issuance that reduces the conversion price below the $1.16 fair value of the common stock on the issuance date of the convertible preferred stock.
