Debt	11. Debt On March 31, 2011, the Company entered into a loan and security agreement with a lender (the “Loan Agreement”) providing for up to an $8.0 million asset based line of credit (the “Line of Credit”). Under the Line of Credit, the Company can borrow up to the lesser of (i) $8.0 million or (ii) 80% of the Company's eligible accounts receivable. Borrowing availability under the Line of Credit changes based upon the amount of eligible receivables, concentration of eligible receivables and other factors. The Company has the ability to obtain letters of credit. Borrowings under the Line of Credit are secured by substantially all of the Company's assets. Outstanding amounts under the Line of Credit accrue interest at a rate equal to the prime rate plus 1.5%. Advances under the Line of Credit were due on March 31, 2013, and interest and related finance charges are payable monthly. On April 29, 2013, the Company amended the Line of Credit to increase the aggregate amount of borrowings that may be outstanding under the Company's asset-based line of credit from $8.0 million to $10.0 million and to extend the maturity date to March 30, 2015. At December 31, 2014 and 2013, the Company had no amounts outstanding under the Line of Credit. On October 3, 2014, the Company amended the Line of Credit and entered into the Third Loan Modification Agreement (the “Modification Agreement”) to (i) increase the aggregate amount of borrowings that may be outstanding under the Company's Line of Credit from $10.0 million to $20.0 million, (ii) increase the aggregate Facility Amount (as defined in the Loan Agreement) available pursuant to the Loan Agreement from $12.5 million to $25.0 million, (iii) provide for an unused line fee of 0.25% of the average unused portion of the Maximum Availability Amount (as defined in the Loan Agreement) per year and (iv) extend the maturity date to October 3, 2016. The interest rate decreased from the prime rate plus 1.5% to the prime rate plus 0.75%. At December 31, 2014 and 2013, the Company had no amounts outstanding under the Line of Credit. Under the Modification Agreement, the Company must comply with certain financial covenants, including maintaining a minimum asset coverage ratio, a minimum net income threshold based on non-GAAP operating measures and a minimum net cash balance at certain points throughout the year. The interest rate will increase to the prime rate plus 2.25% if the Company is not able to meet the minimum asset coverage ratio. Failure to comply with these covenants, or the occurrence of an event of default, could permit the Lenders under the Line of Credit to declare all amounts borrowed under the Line of Credit, together with accrued interest and fees, to be immediately due and payable. In addition, the Line of Credit is secured by substantially all of our assets and places limits on the Company and its subsidiaries ability to incur debt or liens and engage in sale-leaseback transactions, make loans and investments, incur additional indebtedness, engage in mergers, acquisitions and asset sales, transact with affiliates and alter its business. The Company was in compliance with all covenants under the Line of Credit as of December 31, 2014.
