Note 5 - Line of Credit

On September 28, 2022, certain subsidiaries of the Company entered into an Invoice Purchase and Security Agreement (together with an Inventory Finance Rider thereto, the “PSA”) with Alterna Capital Solutions LLC (the “Lender”) providing for (a) the purchase by the Lender of certain of the subsidiaries’ accounts receivable, and (b) financing based upon a percentage of the value of the subsidiaries’ inventory. Pursuant to the PSA, the subsidiaries agree to sell eligible accounts receivable to the Lender for an amount equal to the face amount of each account receivable less a reserve percentage. The maximum amount potentially available to be deployed by the Lender at any given time is $15,000,000, which may be increased to an amount up to $20,000,000. Pursuant to the Inventory Finance Rider to the RSA, the subsidiaries may request advances from time to time based upon the value of the subsidiaries’ inventory. Such advances bear interest at the current prime rate plus 2.25% and are required to be repaid at any time the aggregate outstanding amount of such advances exceed a designated percentage of the value of such inventory.

The PSA provides for the payment of fees by the subsidiaries and includes customary representations and warranties, indemnification provisions, covenants and events of default. Subject in some cases to cure periods, amounts outstanding under the PSA may be accelerated for typical defaults including, but not limited to, the failure to make when due payments, the failure to perform any covenant, the inaccuracy of representations and warranties, the occurrence of debtor-relief proceedings and the occurrence of liens against the purchased accounts receivable and collateral. The subsidiaries have granted the Lender a security interest in all of their respective personal property to secure their obligations under the PSA; provided that the Lender has a first priority security interest in the Subsidiaries’ accounts receivable, payment intangibles and inventory. A named executive officer of the Company granted the Lender a security interest in certain personal property owned by the named executive officer to further secure the Company's obligations under the PSA.

The PSA provides for an initial twenty four (24) month term, followed by automatic annual renewal terms unless the subsidiaries provide written notice pursuant to the PSA prior to the end of any term.

As of March 31, 2023 and December 31, 2022, $3,829,615 and $1,257,301, respectively, was borrowed under the financing agreement. The Company recognized approximately $87,600 in interest expense for the three months ended March 31, 2023 . No amounts under the PSA were outstanding as of March 31, 2022, therefore no interest was recorded in the comparable period in prior year.
