SVB — During October 2017, the Company opened a revolving line of credit with SVB under a three-year agreement. The SVB credit facility is a secured revolving line of credit where borrowings are based on a formula of 200% of repeatable revenue adjusted by an annualized attrition rate as defined in the credit agreement. During the third quarter of 2018, the credit line was increased from $5 million to $10 million and the term was extended for an additional year. Nothing was drawn on this line of credit as of December 31, 2019. At March 31, 2020, the entire line available of $9,750,000 was drawn, although it was subsequently repaid in full during April. Interest on the SVB revolving line of credit is charged at the prime rate plus 1.50%. There is also a fee of one-half of 1% annually for the unused portion of the credit line. The debt is secured by all of the Company’s domestic assets and 65% of the shares in its offshore facilities. Future acquisitions are subject to approval by SVB.
