Stockholders' Equity Note [Abstract] |
Stockholders' Equity Note Disclosure [Text Block] | 10. Stockholders’ Equity On May 23, 2012, the Company amended its Restated Certificate of Incorporation to increase the number of authorized shares of common stock to 24 million shares. At December 31, 2013, the Company had 24.1 million shares authorized, 24 million of which are $0.01 par value common stock and 100,000 of which are $0.01 par value preferred stock. Issuance of Common Stock On November 26, 2012, the Company issued 23,149 restricted shares of its common stock to MDB Capital Group LLC as payment for advisory services. On June 28, 2013, the Company and one of its directors entered into an agreement pursuant to which the director agreed to purchase $100,000 of the Company’s common stock in a private placement at a price of $1.84 per share, the closing bid price on the day preceding the date of the agreement. In July 2013, the Company issued 54,347 shares of common stock to the director under this agreement. Concurrent with its public offering of common stock, on July 3, 2013, the Company paid $235,000 of premium and interest due June 30, 2013, pursuant to loans made to the Company by Kanis S.A., with 188,000 shares of common stock and warrants to purchase 94,000 shares of common stock. The warrants have an exercise price of $1.25 per share, and are exercisable immediately for a period of five years. The Company relied on the private placement exemption provided by Regulation S. The warrants are within the scope of ASC 815-40 “Derivative and Hedging” and are required to be recorded as liabilities (see note 11). As such, the fair value of the warrants were recorded as a warrant liability on the issuance date. Shelf Registration On May 15, 2012, the Company filed a Shelf Registration which was declared effective by the SEC on May 21, 2012. The Shelf Registration permits the Company to sell, from time to time, up to an aggregate of $50.0 million of various securities, including common stock, preferred stock, warrants to purchase common stock or preferred stock and units consisting of one or more shares of common stock, shares of preferred stock, warrants, or any combination of such securities. However, the Company may not sell its securities in a primary offering pursuant to the Shelf Registration or any other registration statement on Form S-3 with a value exceeding one-third of its public float in any 12-month period (unless the Company’s public float rises to $75.0 million or more). The Shelf Registration is intended to provide the Company with additional flexibility to access capital markets for general corporate purposes, subject to market conditions and the Company's capital needs. On June 28, 2013, the Company entered into an underwriting agreement (the “Underwriting Agreement”) with Roth Capital Partners, LLC, (the “Underwriter”) related to the public offering (the “Offering”) of an aggregate 1,600,000 shares of the Company’s common stock together with warrants to purchase up to 800,000 shares of common stock. The Underwriters were also granted a 30 day option to purchase up to an additional 240,000 shares of common stock and/or warrants to purchase up to an additional 120,000 shares of common stock to cover overallotments, if any. The offering was made pursuant to the Company’s Shelf Registration discussed above. On July 3, 2013, the Company closed the offering in which it sold 1,730,000 shares of common stock at a price of $1.245 per share and warrants to purchase up to 865,000 shares at a price per warrant of $0.01 (the “Offering Warrants”), including 130,000 shares and 65,000 warrants upon partial exercise of the Underwriter’s over-allotment option. The securities were sold in units consisting of one share of common stock and one half of a warrant to purchase one share of common stock for a price of $1.25 per unit. The Offering Warrants have an exercise price of $1.25 per share, and are exercisable immediately for a period of five years. Subsequent to December 31, 2013, warrant holders exercised an aggregate of 800,000 of warrants issued in the offering at an exercise price of $1.25 per share for gross proceeds of $1.0 million. The Company received gross proceeds of $2.2 million and net proceeds of approximately $1.7 million after deducting discounts and commissions to the Underwriter and offering expenses. The Offering Warrants are within the scope of ASC 815-40 and are required to be recorded as liabilities (see note 11). Accordingly, of the $1.7 million in net proceeds, $1.1 million was allocated to the common stock and included in additional paid-in capital and $0.7 million was allocated to the warrant liability based on the fair value of the warrants on the issuance date. Additionally, $0.1 million of the underwriting discounts and commissions and offering costs were allocated to the Offering Warrants, based on the relative fair value of the Offering Warrants and the common stock on the issuance date, and is included in other expense, net in the accompanying statement of comprehensive loss for the year ended December 31, 2013. The Company used the proceeds for general corporate purposes, including working capital, general and administrative expenses, capital expenditures and implementation of its strategic priorities, and to repay a portion of amounts outstanding under its line of credit. In accordance with the Underwriting Agreement, the Company issued the Underwriter a warrant to purchase in aggregate 34,600 shares of the Company’s common stock with an exercise price of $1.25 per share. The warrant is exercisable beginning on December 25, 2013 through June 28, 2018. The fair value of the warrants, which approximated zero, was accounted for as a cost of the offering. Common Stock Purchase Agreement with LPC On October 7, 2011, the Company signed a Purchase Agreement with LPC, together with a Registration Rights Agreement, whereby LPC agreed to purchase up to $10.0 million of the Company’s common stock over a 30-month period ending April 24, 2014. Pursuant to the Registration Rights Agreement, the Company filed a registration statement on Form S-1 with the SEC on October 13, 2011 covering 1,823,577 shares that have been issued or may be issued to LPC under the Purchase Agreement. Of the shares registered, 40,247 shares were issued to LPC as a commitment fee upon entering into the Purchase Agreement; 80,494 shares may be issued to LPC pro rata as an additional commitment fee as up to $10.0 million of the Company’s common stock is purchased by LPC; and 1,702,836 represent shares that the Company may sell to LPC under the Purchase Agreement. The registration statement related to the transaction was declared effective by the SEC on December 5, 2011. Accordingly, the Company has the right, in its sole discretion, over a 30-month period to sell shares of its common stock to LPC in amounts of up to $0.5 million to up to $1.5 million per sale, depending on certain conditions as set forth in the Purchase Agreement, up to the aggregate amount of $10.0 million. T he aggregate number of shares issued pursuant to the Purchase Agreement is limited to 1,434,994 shares of common stock (19.99% of the outstanding shares of the Company’s common stock on October 7, 2011, the date of the Purchase Agreement) (the “Exchange Cap”), unless and until shareholder approval is obtained. The Exchange Cap is not applicable for at-market transactions, defined as when the average price for all shares purchased pursuant to the purchase agreement is greater than or equal the signing price of $2.76 plus $0.254, or $3.014 per share. There have been no sales to date under this arrangement. There are no upper limits to the price LPC may pay to purchase the Company’s common stock and the purchase price of the shares related to the $10.0 million of future funding will be based on the prevailing market prices of the Company’s shares preceding the time of sales as computed in accordance with the Purchase Agreement without any fixed discount, with the Company controlling the timing and amount of future sales, if any, of shares to LPC. The purchase price per share is equal to the lesser of the lowest sales price of the Company’s common stock on the purchase date or the average of the three lowest closing sales prices of the Company’s common stock during the twelve consecutive business days prior to the date of the purchase by LPC. LPC has agreed not to cause or engage in any manner whatsoever, any direct or indirect short selling or hedging of the Company’s shares of common stock. The Company may terminate the Purchase Agreement at any time at its discretion without any cost or penalty. Any proceeds received by the Company under the Purchase Agreement are expected to be used for working capital and general corporate purposes.
