DEBT

Financing Agreements

In June 2012, the Company entered into a revolving credit facility with Silicon Valley Bank (the revolving credit facility) for a principal amount of up to $10.0 million, with a sublimit of $3.0 million for borrowings guaranteed by the Export-Import Bank of the United States. The revolving credit facility is collateralized by substantially all of the Company’s property, other than intellectual property. Prior to March 31, 2015, the revolving credit facility bore monthly interest at a floating rate equal to the greater of (i) 4.00% or (ii) prime rate plus 0.75%. By amendment in March 2015, interest on the credit facility adjusted as of March 31, 2015 to a floating rate equal to the lesser of (i) LIBOR rate plus 2.25% or (ii) prime rate minus 0.5%. In November 2015, the Company further amended the revolving credit facility to revise the floating interest rate to the lesser of (i) LIBOR rate plus 1.75% or (ii) prime rate minus 1.0%, which is effective January 1, 2016.

The revolving credit facility currently provides among other things, (i) a maturity date of March 31, 2017; (ii) no sublimit for borrowings guaranteed by the Export-Import Bank; and (iii) a revolving line up to $20.0 million, subject to certain conditions.

The revolving credit facility contains customary negative covenants which, unless approved by SVB, limit the Company’s ability to, among other things, incur additional indebtedness, grant liens, make investments, repurchase stock, pay dividends, transfer assets and merge or consolidate, as well as requiring the Company to maintain a minimum adjusted quick ratio of 1.25 to 1.00 and minimum cash balances as of the last day of each month. The revolving credit facility also contains customary events of default, subject to customary cure periods for certain defaults, that include, among other things, non-payment defaults, covenant defaults, material judgment defaults, bankruptcy and insolvency defaults, cross-defaults to certain other material indebtedness, and inaccuracy of representation and warranties. Upon an event of default, the lender may declare all or a portion of the outstanding obligations payable by the Company to be immediately due and payable and exercise other rights and remedies provided for under the credit facility. During the existence of an event of default, interest on the obligations under the credit facility could be increased by 5.0%. As of December 31, 2015 and December 31, 2014, the Company was in compliance with these covenants.

As of December 31, 2015, $20.0 million remains outstanding under the revolving credit facility.

In August 2013, the Company entered into a term loan credit facility with TriplePoint Capital LLC (the term loan credit facility) that allowed the Company, subject to certain funding conditions including compliance with certain covenants and the absence of certain events or conditions that could have been deemed to have a material adverse effect on the Company's business, to borrow money under term loans in an aggregate principal amount of up to $20.0 million. In December 2013, the Company borrowed $10.0 million under the term loan credit facility under two separate loans. The stated interest rate for each loan was 10.75% and 9.75%, respectively, and was reduced to 10.25% and 9.25%, respectively, due to the completion of the IPO in 2014. In the first quarter 2015, the Company elected to voluntarily repay in full all of its outstanding obligations under the term loan credit facility, along with an end-of-term payment of $0.3 million, and terminated the facility.
