On April 17, 2020, CSP, Inc. and Modcomp, Inc., its wholly owned subsidiary (collectively, the “Borrowers”) each received a loan in the form of a promissory note from Paragon Bank (“Lender”) in the amounts of $827,000 and $1,353,600, respectively (the “SBA Loans”) under the Paycheck Protection Program (“PPP”), which was established under the recently enacted Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) administered by the U.S. Small Business Administration (“SBA”). The SBA Loans have a two-year term and carry an annual fixed interest rate of 1%.

The SBA Loans provided for customary events of default, including, among others, those relating to failure to make payment, bankruptcy, materially false or misleading representations to Lender or SBA, and adverse changes in the financial condition or business operations that Lender believed could materially affect Borrowers’ ability to pay the SBA Loans. The Borrowers did not provide any collateral or guarantees for the SBA Loans and the Borrowers could prepay the principal of the SBA Loans at any time without penalty.

The Borrowers applied to the Lender for forgiveness of an amount due on the SBA Loans in an amount equal to the sum of certain costs during the 24 week period beginning on the date of the first disbursement of the SBA Loans. The amount of SBA Loans forgiveness was calculated in accordance with the requirements of the PPP, including provisions of Section 1106 of the CARES Act. We used the SBA Loans proceeds in accordance with the applicable SBA guidelines. In November 2020 the SBA Loans were formally forgiven. The $2.2 million gain is displayed on the Consolidated Statement of Operations in the line item “Gain on forgiveness of debt.”
