Debt Disclosure [Abstract]
Debt	9. DEBT On March 15, 2013, the Company executed loan documents with Hercules Technology Growth Capital Inc. (“Hercules”), a venture capital lender, whereby the Company borrowed $6 million (the “Loan”). The Loan accrued interest at a rate of 10.45%. The term of the Loan was 42 months with interest payments only during the first 12 months. On September 10, 2013, the Company elected to prepay the Loan and paid Hercules approximately $6.4 million, including the end of term fee of $425,000, to settle all obligations to Hercules. Hercules agreed to waive the prepayment penalty of $180,000. Upon executing the loan documents on March 15, 2013 the Company became obligated to issue to the Lender a warrant to purchase shares of the Company’s common stock upon approval by the Company’s stockholders of a proposal to increase the Company’s number of authorized shares of common stock at its 2013 Annual Meeting of Stockholders. The number of shares that could be acquired upon exercise of the warrant and the exercise price per share were not fixed on March 15, 2013, but would be determined when the warrant was issued based on a defined formula using trading prices of the Company’s common stock during certain periods prior to the issuance of the warrant. The Company’s stockholders approved the increase in the number of authorized shares of common stock on April 25, 2013 and on April 26, 2013 the warrant was issued to the Lender. The terms of the warrant were fixed on the date of issuance whereby the Lender received a warrant to purchase 69,321 shares of common stock at an exercise price of approximately $11.20 per share. The warrant expires on April 26, 2018. For financial reporting purposes, the $6 million funded by the Lender on March 15, 2013 was allocated first to the fair value of the obligation to issue the warrant, which totaled approximately $563,000, and the balance was reduced further by the Lender’s costs and fees, resulting in an initial carrying value of the loan of approximately $5.3 million. The Company used a Level 3 fair value measurement to determine fair value of the warrant obligation, which has significant unobservable inputs as defined in Accounting Standards Codification 820 “Fair Value Measures”. During the period from the loan inception date until the warrant obligation was fulfilled and the warrant was issued, the warrant obligation was reflected as a long-term liability at fair value. Changes in the fair value (“mark-to-market adjustments”) of the warrant obligation of approximately $105,292 and $89,859 are included in operating results for the three and six months ended June 30, 2013. The fair value of the warrant obligation was determined using the Monte Carlo pricing model that used various assumptions that included: stock prices ranging from $11.60 to $11.80 per share, volatility of 77%, time to maturity of 5 years, exercise prices ranging from $11.50 to $11.60 and a risk free interest rate of return of .84%. Under the Monte Carlo model, a 10% change in the underlying unobservable inputs would not have a significant impact on the fair value. The value of the warrant obligation combined with the costs resulted in an initial loan discount of approximately $727,000. The terms of the Loan required us to pay the Lender a fee of $425,000 at the maturity of the Loan. The loan discount and the fee were being amortized as additional interest expense over the life of the loan using the interest method. As discussed above, prior to the terms of the warrant being fixed on April 26, 2013, the warrant obligation fell within the scope of Accounting Standards Codification 815 “Derivatives and Hedging” (“ASC 815”) and therefore the warrant obligation was accounted for as a derivative reflected as a long-term liability until the warrant was issued on April 26, 2013. The terms of the warrant upon issuance no longer required derivative accounting under ASC 815 and therefore the fair value of the warrant was classified within stockholders equity. As the result of the Company electing to prepay the loan on September 10, 2013, the unamortized loan discount, fee and deferred financing costs that were expensed at that date were approximately $1.0 million.
