Line of credit facility interest rate description | The Company will be required to pay interest on borrowings outstanding, if any, under the revolving line of credit at a floating rate per annum equal to 1% above the Wall Street Journal prime rate (4.75% as of December 31, 2019) (or, if unavailable, the Silicon Valley Bank prime rate) on a monthly basis, so long as the Company maintains a liquidity ratio of cash and cash equivalents plus accounts receivable to outstanding debt under the Amended Loan Agreement minus deferred revenue of 1.50 to 1.00. If this liquidity ratio is not met, the Company will be subject to a minimum interest charge of $3 thousand per month and borrowings outstanding, if any, under the revolving line of credit will accrue interest at a floating rate per annum equal to 2% above the Wall Street Journal prime rate (4.75% as of December 31, 2019) (or, if unavailable the Silicon Valley Bank prime rate) on a monthly basis. Prior to the amendment in January 2018, the revolving line of credit bore interest rate at the U.S. prime rate plus 1.25%. The revolving line of credit matured on January 31, 2020 and was not renewed. | |||||
