Stockholders' Equity Note [Abstract] |
STOCKHOLDERS’ EQUITY | STOCKHOLDERS’ EQUITY Common Stock. Pursuant to our Third Amended and Restated Certificate of Incorporation, as amended, we currently have 150,000,000 shares of common stock authorized for issuance. On February 2, 2012, we entered into definitive agreements with institutional and other accredited investors and raised approximately $22.0 million in a private placement financing (the “Private Placement”), which includes an aggregate of $3.0 million in convertible notes (the “Convertible Notes”) issued in December 2011 to entities affiliated with Third Security, LLC (the “Third Security Investors”), a related party, that automatically convert into shares of our common stock and warrants to purchase such common stock on the same terms as all investors in the Private Placement. Pursuant to the applicable purchase agreement, we issued an aggregate of 1,583,333 shares of our common stock at a price per share of $12.00, as well as five-year warrants to purchase up to an aggregate of 823,333 shares of common stock with an exercise price of $15.00 per share. In connection with the conversion of the Convertible Notes, the Third Security Investors received an aggregate of 250,000 shares of common stock and 125,000 warrants on the same terms as all investors in the Private Placement. Craig-Hallum Capital Group LLC served as the sole placement agent for the offering. In consideration for services rendered as the placement agent in the offering, we agreed to (i) pay to the placement agent cash commissions equal to $1,330,000, or 7.0% of the gross proceeds received in the offering, (ii) issue to the placement agent a five-year warrant to purchase up to 31,666 shares of our common stock (representing 2% of the shares sold in the Private Placement) with an exercise price of $15.00 per share and other terms that are the same as the terms of the warrants issued in the Private Placement; and (iii) reimburse the placement agent for reasonable out-of-pocket expenses, including fees paid to the placement agent’s legal counsel, incurred in connection with the offering, which reimbursable expenses were not to exceed $125,000. The costs incurred to complete the Private Placement were recorded as a reduction in equity in the amount of $1.5 million. Net proceeds from this offering have been used for general corporate and working capital purposes, primarily to accelerate development of several of our key initiatives. On January 24, 2013, we entered into a Securities Purchase Agreement with certain institutional and other accredited investors pursuant to which we: (i) sold to the investors an aggregate of 1,383,333 shares of our common stock at a price per share of $6.00 for aggregate gross proceeds of approximately $8.3 million; and (ii) issued to the investors warrants to purchase up to an aggregate of 691,656 shares of our common stock with an exercise price of $9.00 per share (the “Offering”). The warrants may be exercised, in whole or in part, at any time from January 30, 2013 until January 30, 2018 and contain both cash and “cashless exercise” features. The Third Security Investors purchased an aggregate of 500,000 shares of common stock and warrants to purchase an aggregate of 250,000 shares of common stock in the Offering on the same terms as the other investors. We used the net proceeds from the Offering for general corporate and working capital purposes. In connection with the Offering, we entered into a registration rights agreement with the investors (the “Registration Rights Agreement”). The Registration Rights Agreement required that we file with the Securities and Exchange Commission (the “SEC”) a registration statement to register for resale the shares of common stock sold and the shares of common stock issuable upon exercise of the warrants by March 16, 2013. The registration statement was filed with the SEC on March 15, 2013 and was declared effective by the SEC on March 29, 2013. The January 2013 common stock transaction required the repricing and issuance of additional common stock warrants to the holders of warrants issued in the February 2012 common stock and warrant sale. The exercise price of the warrants decreased from $15.00 per share to $12.96 per share and the number of shares issuable upon exercise of the warrants increased from 948,333 to 1,097,600. On October 22, 2014, we entered into a Securities Purchase Agreement with certain accredited investors (the “October 2014 Investors”), pursuant to which we, in a private placement, issued and sold to the October 2014 Investors (the “2014 Private Placement”) an aggregate of 730,776 shares of our common stock at a price per share of $3.25 for an aggregate purchase price of approximately $2.375 million, and warrants to purchase up to an aggregate of 365,388 shares of our common stock with an initial exercise price of $4.00 per share that are exercisable for the period from April 22, 2015 through April 22, 2020. In connection with the 2014 Private Placement, we also issued a warrant to purchase up to an aggregate of 9,230 shares of our common stock to one advisor. The warrants issued in the 2014 Private Placement include both cash and “cashless exercise” features. The 2014 Private Placement required the repricing and issuance of additional common stock warrants to the holders of warrants issued in the February 2012 common stock and warrant sale. The exercise price of the warrants decreased from $11.73 per share to $10.86 per share and the number of shares issuable upon exercise of the warrants increased from 1,212,665 to 1,309,785. On December 31, 2014, we entered into the Note Purchase Agreement with the Investor pursuant to which we agreed to issue and sell the Initial note to the Investor (the “Note Private Placement”). See Note 6 “Debt-Convertible Promissory Notes” for additional information regarding the terms of the Initial note. Pursuant to the terms of the Note Purchase Agreement, we are subject to certain registration obligations and we may be required to effect one or more other registrations to register for resale the shares of our common stock issued or issuable under the Initial Note in connection with certain “piggy-back” registration rights granted to the Investor. The Note Private Placement required the repricing and issuance of additional common stock warrants to the holders of warrants issued in the February 2012 common stock and warrant sale. The exercise price of the 2012 warrants decreased from $10.86 per share to $10.25 per share and the number of shares issuable upon exercise of the warrants increased from 1,309,785 to 1,387,685. On January 15, 2015, we entered into the Note Purchase Agreement with the Additional Investors and, on January 20, 2015, issued and sold to the Additional Investors, in a private placement, the Additional Notes in an aggregate principal amount of $925,000 (the “Additional Note Private Placement”). The Additional Notes have the same terms and conditions as the Initial Note. Craig-Hallum acted as the sole placement agent for the sale and issuance of the Additional Notes. In connection with the sale and issuance of the Additional Notes, we issued to Craig-Hallum an unsecured convertible promissory note, upon the same terms and conditions as the Notes, in an aggregate principal amount equal to 5% of the proceeds received by us pursuant to the sale and issuance of the Additional Notes, or $46,250. As of the date of filing of this Annual Report, the Placement Agent Note remains outstanding. The Additional Note Private Placement required the repricing and issuance of additional common stock warrants to the investors in our February 2012 common stock and warrant financing. The exercise price of these warrants decreased from $10.25 per share to $9.59 per share and the number of shares issuable upon exercise of the warrants increased from 1,387,685 to 1,483,161. On February 27, 2015, we entered into a purchase agreement with Craig-Hallum Capital Group LLC (the “Underwriter”) relating to our sale and issuance of 3,573,899 shares of our common stock and corresponding warrants to purchase up to 714,780 shares of our common stock (the “2015 Offering”). Each share of common stock was sold in combination with a warrant to purchase 0.20 of a share of common stock. The purchase price to the public for each share of common stock and accompanying warrant was $1.95. The purchase price paid by the Underwriter to us for the common stock and accompanying warrants was $1.8135. The net proceeds from the 2015 Offering, after deducting the Underwriter’s discount and other estimated 2015 Offering expenses, were approximately $6.2 million. The accompanying warrants are exercisable immediately upon their initial issuance date at an exercise price of $2.24 per share and will expire five years from the date of issuance. The exercise price will also be subject to adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations, reclassifications or similar events affecting our common stock. The 2015 Offering required the repricing and issuance of additional common stock warrants to the investors in our February 2012 common stock and warrant financing. The exercise price of these warrants decreased from $9.59 per share to $7.56 per share and the number of shares issuable upon exercise of the warrants increased from 1,483,161 to 1,881,396. On June 30, 2015, we entered into a Securities Purchase Agreement with certain accredited investors (the “July 2015 Investors”) pursuant to which, on July 7, 2015, we sold to the July 2015 Investors, and the July 2015 Investors purchased from us, (a) an aggregate of approximately 1.5 million shares of our common stock at a price per share of $1.42, (b) warrants (the “Series B Warrants”) to purchase up to an aggregate of 0.7 million shares of our common stock with an exercise price of $0.01 per share, and (c) warrants (the “Series A Warrants” and, together with the Series B Warrants, the “July 2015 Warrants”) to purchase up to an aggregate of 1.2 million shares of our common stock, with an exercise price of $1.66 per share (collectively, the “July 2015 Offering”). The purchase price for the Series B Warrants was $1.42 per share of our common stock subject to the Series B Warrants. Each of the July 2015 Warrants has a term of 5 and 1/2 years. The Series B Warrants are immediately exercisable. The Series A Warrants will be exercisable beginning on January 7, 2016, six months from the date of issuance. The aggregate gross proceeds to us from the July 2015 Offering were approximately $3.0 million. Craig-Hallum Capital Group LLC (the “2015 Placement Agent”) served as the sole placement agent for the Offering. In consideration for services rendered as the placement agent in the July 2015 Offering, we (a) paid to the 2015 Placement Agent cash commissions equal to approximately $212,783, or 7.0% of the gross proceeds received in the July 2015 Offering; (b) issued to the 2015 Placement Agent a five-year warrant to purchase up to 107,033 shares of our common stock with an exercise price of $1.66 per share and which is subject to other terms that are the same as the terms of the Series A Warrants; and (c) reimbursed the 2015 Placement Agent for reasonable out-of-pocket expenses, including fees paid to the 2015 Placement Agent’s legal counsel, incurred in connection with the July 2015 Offering, which reimbursable expenses did not exceed $50,000. The July 2015 Offering required the repricing and issuance of additional common stock warrants to the investors in our February 2012 common stock and warrant financing. The exercise price of these warrants decreased from $7.56 per share to $6.50 per share and the number of shares issuable upon exercise of the warrants increased from 1,881,396 to 2,188,177. Common Stock Warrants. During the twelve months ended December 31, 2015, we issued warrants to purchase 3,466,841 shares of common stock and none of the issued warrants were exercised. Included in the warrants issued in 2015 were 800,492 warrant issued due to repricing requirements of the Private Placement and 2,666,349 warrants issued in connection with the 2015 Offering and the July 2015 Offering. During the twelve months ended December 31, 2015, warrants to purchase 431,027 shares of common stock expired. There were 664,703 common stock warrants issued during the 12 months ended December 31, 2014 and none of the issued warrants were exercised. Included in the warrants issued in 2014 were 290,085 warrants issued due to re-pricing requirements of the Private Placement. Warrants to purchase an aggregate of 5,920,799 shares of common stock were outstanding at December 31, 2015.

Preferred Stock Series A. The Company’s Board of Directors is authorized to issue up to 15,000,000 shares of preferred stock in one or more series, from time to time, with such designations, powers, preferences and rights and such qualifications, limitations and restrictions as may be provided in a resolution or resolutions adopted by the Board of Directors. The authority of the Board of Directors includes, but is not limited to, the determination or fixing of the following with respect to shares of such class or any series thereof: (i) the number of shares; (ii) the dividend rate, whether dividends shall be cumulative and, if so, from which date; (iii) whether shares are to be redeemable and, if so, the terms and amount of any sinking fund providing for the purchase or redemption of such shares; (iv) whether shares shall be convertible and, if so, the terms and provisions thereof; (v) what restrictions are to apply, if any, on the issue or reissue of any additional preferred stock; and (vi) whether shares have voting rights. The preferred stock may be issued with a preference over the common stock as to the payment of dividends. We have no current plans to issue any additional preferred stock. Classes of stock such as the preferred stock may be used, in certain circumstances, to create voting impediments on extraordinary corporate transactions or to frustrate persons seeking to effect a merger or otherwise to gain control of the Company. For the foregoing reasons, any additional preferred stock issued by the Company could have an adverse effect on the rights of the holders of the common stock. On December 29, 2010, we entered into a transaction with the Third Security Investors, pursuant to the terms of a Series A Convertible Preferred Stock Purchase Agreement (the “Series A Purchase Agreement”), in which we: (i) sold an aggregate of 2,586,205 shares of Series A Preferred Stock at a price of $2.32 per share; and (ii) issued Series A Warrants to purchase up to an aggregate of 1,293,102 shares of Series A Preferred Stock having an exercise price of $2.32 per share (the sale of Series A Preferred Stock and issuance of the Series A Warrants hereafter referred to together as the “Financing”). The Series A Warrants may be exercised at any time from December 29, 2010 until December 28, 2015 and contain a “cashless exercise” feature. The gross proceeds from the Series A financing were $6.0 million. The $0.2 million of costs incurred to complete the Series A financing were recorded as a reduction in the value of the Series A Preferred Stock. We used the net proceeds from the financing to acquire the FAMILION family of genetic tests from PGxHealth, a subsidiary of Clinical Data, Inc. Until the November 2011 modifications, the Series A Preferred Stock met the definition of mandatorily redeemable stock as it was preferred capital stock that was redeemable at the option of the holder through December 2015 and was reported outside of equity. The Series A Preferred Stock was to be accreted to its redemption value of $6.0 million. Until the November 2011 modifications, the Series A Warrants did not qualify to be treated as equity and, accordingly, were recorded as a liability. A preferred stock anti-dilution feature is embedded within the Series A Preferred Stock that met the definition of a derivative. In connection with the Series A financing, we filed a Certificate of Designation of Series A Convertible Preferred Stock (the “Series A Certificate of Designation”) with the Secretary of State of the State of Delaware, designating 3,879,307 shares of our preferred stock as Series A Preferred Stock. As of December 31, 2013, the Series A Preferred Stock, including the Series A Preferred Stock issuable upon exercise of the Series A Warrants, was convertible into shares of our common stock at a rate of 4-for-1, which conversion rate is subject to further adjustment as set forth in the Series A Certificate of Designation. Giving effect to the reverse split of our stock in January 2014, the conversion rate was adjusted to 1-for-3. Certain rights of the holders of the Series A Preferred Stock are senior to the rights of the holders of our common stock. The Series A Preferred Stock has a liquidation preference equal to its original price per share, plus any accrued and unpaid dividends thereon. The holders of the Series A Preferred Stock are entitled to receive quarterly dividends, which accrue at the rate of 10% of the original price per share per annum, whether or not declared, and which shall compound annually and shall be cumulative. In any calendar quarter in which we have positive distributable cash flow as defined in the Series A Purchase Agreement, we are required to pay from funds legally available a cash dividend in the amount equal to the lesser of 50% of such distributable cash flow or the aggregate amount of dividends accrued on the Series A Preferred Stock. Generally, the holders of the Series A Preferred Stock are entitled to vote together with the holders of common stock, as a single group, on an as-converted basis. However, the Series A Certificate of Designation provides that we shall not perform some activities, subject to certain exceptions, without the affirmative vote of a majority of the holders of the outstanding shares of Series A Preferred Stock. The holders of the Series A Preferred Stock, along with the holders of the Series B Preferred Stock, also are entitled to elect or appoint, as a single group, two directors of the Company. In connection with the Series A financing, we also entered into a registration rights agreement with the Third Security Investors (the “Registration Rights Agreement”). Pursuant to the terms of the Registration Rights Agreement, the Company has granted certain demand, “piggyback” and S-3 registration rights covering the resale of the shares of common stock underlying the Series A Preferred Stock issued pursuant to the Series A Purchase Agreement and issuable upon exercise of the Series A Warrants and all shares of common stock issuable upon any dividend or other distribution with respect thereto. In November 2011, we entered into a transaction with the Third Security Investors, pursuant to an Agreement Regarding Preferred Stock (the “Amendment Agreement”), in which the Third Security Investors agreed to (i) waive their rights to enforce the anti-dilution and redemption features of the Series A Preferred Stock and (ii) at the next annual stockholders’ meeting, vote to amend the Series A Certificate of Designation to remove the anti-dilution and redemption features of the Series A Preferred Stock. In exchange, the Company issued shares of common stock to the Third Security Investors having an aggregate market value of $0.3 million. As a result of the Amendment Agreement, the values of the Series A Preferred Stock and Series A Warrants, including the Series A Preferred Stock conversion feature and Series A Warrant liability, were reclassified into stockholders’ equity as of the date of the Amendment Agreement. The Series A Preferred Stock was converted into common stock on January 6, 2016 (See Note 15 - “Subsequent Events - Conversion of Preferred Stock”). Preferred Stock Series B. On March 5, 2014, we entered into a Series B Convertible Preferred Stock Purchase Agreement (the “Series B Purchase Agreement”) with affiliates of Third Security, LLC (the “2014 Third Security Investors”), pursuant to which we, in a private placement, sold and issued an aggregate of 1,443,297 shares of our Series B Preferred Stock, par value $0.01 per share (the “Series B Preferred Stock”), at a price per share of $4.85 for an aggregate purchase price of approximately $7.0 million. Each share of Series B Preferred Stock issued pursuant to the Series B Purchase Agreement is initially convertible into shares of our common stock at a rate of 1-for-1, which conversion rate is subject to further adjustment as set forth in the Certificate of Designation of Series B Convertible Preferred Stock. In connection with the Series B financing, we also entered into a Registration Rights Agreement, dated March 5, 2014, with the 2014 Third Security Investors, pursuant to which we granted certain demand, “piggy-back” and S-3 registrations rights covering the resale of the shares of common stock underlying the Series B Preferred Stock issued pursuant to the Series B Purchase Agreement and all shares of common stock issuable upon any dividend or other distribution with respect thereto. The Series B financing required the repricing and issuance of additional common stock warrants to the holders of warrants issued in the Private Placement. The exercise price of the warrants decreased from $12.96 per share to $11.73 per share and the number of shares issuable upon exercise of the warrants increased from 1,097,600 to 1,212,665. The Series B Preferred Stock was converted into common stock on January 6, 2016 (See Note 15 - “Subsequent Events - Conversion of Preferred Stock”). Preferred Stock Dividends. We have cumulative undeclared dividends on our Series A Convertible Preferred Stock and Series B Preferred Stock (collectively “Preferred Stock”). At December 31, 2014, we had a recorded liability of $3.1 million for these undeclared dividends. Since dividends should generally not be recognized as a liability until declared, the $3.1 million liability was reversed in 2015 with an offset to accumulated deficit. For the twelve months ended December 31, 2015 and 2014, we had cumulative undeclared dividends on our Preferred Stock of $4.4 million and $3.1 million, respectively. In accordance with the FASB’s Accounting Standards Codification Topic 260-10-45-11, “Earnings per Share”, these dividends were added to the net loss per share calculation. The accrued dividends were paid through the issuance of common stock on January 6, 2016 (See Note 15 - “Subsequent Events - Conversion of Preferred Stock”).
