Debt Disclosure [Abstract] |
Debt | Debt Senior Secured Term Loans On December 19, 2014, the Company entered into a second amendment to its Loan and Security Agreement with Hercules (the “Hercules Second Amendment”) and entered into a new term loan, borrowing an additional $1.5 million (the “Term Loan C”). After closing fees and expenses, the net proceeds to the Company for the Term Loan C were $1.4 million. The Company made interest only payments at an interest rate of 11% through March 16, 2017 when the interest rate was increased to 11.25%, until maturity on June 1, 2017, when Term Loan C was repaid in its entirety. Hercules received warrants to purchase 13,927 shares of common stock (the “First Warrant”) and 25,641 shares of common stock (the “Second Warrant”) in conjunction with prior term loans that have been repaid in full. Due to certain adjustment provisions within the warrants, they qualified for liability accounting. The fair value of the warrants, $0.4 million and $0.2 million, respectively, was recorded upon issuance to debt discount and a warrant liability. In conjunction with the Hercules Second Amendment, the First Warrant and Second Warrant were cancelled and replaced with the issuance of a new warrant (the “Hercules Warrant”) to purchase 58,823 shares of common stock at an exercise price of $11.00 per share, subject to adjustment. The Hercules Warrant expires on June 30, 2020. See Note 11, “Warrants and Derivative Liabilities”, for a discussion on the Hercules Warrant and the valuation assumptions used. During the three months ended June 30, 2016, the Company recorded non-cash interest expense for amortization of the debt discount related to a prior term loan of less than $0.1 million. Under Term Loan C, the total debt discount, including the Hercules Warrant, end of term fee and legal and origination costs of $0.3 million was amortized into interest expense over the term of the Term Loan C using the effective interest method. During each of the three months ended June 30, 2017 and 2016, the Company recorded non-cash interest expense for amortization of the debt discount related to the Term Loan C of less than $0.1 million. Interest expense on the Term Loans for the three months ended June 30, 2017 and 2016, was less than $0.1 million and $0.2 million, respectively, each of which included less than $0.1 million of non-cash interest expense related to the amortization of the debt discount on the respective Term Loans.
