We entered into a Loan and Security Agreement with Silicon Valley Bank (“SVB”) on July 23, 2010, which, as amended, provides for a revolving line of credit for the lesser of $2,500,000, or 80% of eligible accounts receivable. The line of credit matures on February 14, 2022, and is subject to certain financial and performance covenants with which we were in compliance as of September 30, 2021. Financial covenants include maintaining an adjusted quick ratio of unrestricted cash and net accounts receivable, divided by current liabilities plus debt less deferred revenue of at least 1.15 to 1.0, and maintaining tangible net worth of $1,500,000, plus 50% of net income for the fiscal quarter ended from and after December 31, 2017, plus 50% of the dollar value of equity issuances after October 1, 2017 and the principal amount of subordinated debt. The line of credit bears interest at an annual rate equal to the greater of 1% above the prime rate and 5.5%. The interest rate on the line of credit was 5.5% as of September 30, 2021.

Non-GAAP Measure – Adjusted EBITDA
In addition to our GAAP results, we present Adjusted EBITDA as a supplemental measure of our performance. However, Adjusted EBITDA is not a recognized measurement under GAAP and should not be considered as an alternative to net income, income from operations or any other performance measure derived in accordance with GAAP or as an alternative to cash flow from operating activities as a measure of liquidity. We define Adjusted EBITDA as net income (loss), plus interest expense, other income (expense), foreign currency transaction loss, provision for income taxes, depreciation and amortization, stock-based compensation, income from discontinued operations and gain on sale of discontinued operations. Management considers our core operating performance to be that which our managers can affect in any particular period through their management of the resources that affect our underlying revenue and profit generating operations that period. Non-GAAP adjustments to our results prepared in accordance with GAAP are itemized below. You
