Long-term Debt and Other Credit Arrangements Long-term Debt and Other Credit Arrangements
On May 6, 2013, the Company entered into a credit and security agreement (the "Loan Agreement") consisting of a $20 million revolving credit facility ("Line of Credit") with Wells Fargo, National Bank, which originally matured in May 2018 and was extended numerous times until it was terminated in June 2022.
On June 19, 2019, the Company entered into a Security Agreement with Wells Fargo, National Bank, pursuant to which the Company granted a security interest in substantially all of its assets to secure its obligations under the Loan Agreement. On December 13, 2019, the Company entered into an amendment to the Loan Agreement and the Line of Credit to effect a change to an asset based lending arrangement based on eligible accounts receivable and inventory, with the available amount not to exceed $20 million through January 31, 2020, and with such maximum amount reduced to $15 million thereafter. This amendment replaced the prior financial covenants with new financial covenants, including minimum monthly liquidity and EBITDA requirements. Additionally, a requirement for the repatriation of foreign cash and restrictions on the payment of dividends were added. The Security Agreement was amended several times during fiscal years 2022 and 2023 as the Company was finalizing the Sale-Leaseback financing transaction discussed in Note 5, Sale-Leaseback Financing Transaction. These amendments were primarily driven by requirements and timing of the Company's new credit arrangement.
On June 27, 2022, the Company terminated the Credit Agreement with Wells Fargo, National Bank. At the time of termination, there were no borrowings under the Credit Agreement, and the Company did not incur any material termination penalties as a result of the termination.
At April 30, 2022, there were advances of $1.6 million and $716,000 in letters of credit outstanding, leaving $2.4 million available under the Line of Credit. The borrowing rate under the Line of Credit at that date was 4.75%. Monthly interest payments under the Line of Credit were payable at the greater of the Daily One Month LIBOR interest rate, or 0.75%, plus 4.0%. At April 30, 2022, the Company was in compliance with all the financial covenants under its revolving credit facility.
On December 19, 2022, the Company entered into a Credit and Security Agreement (the "Credit Agreement") with Mid Cap Funding IV Trust, as agent (the "Agent"), and the lenders from time to time party thereto (collectively, the "Lenders"). The Credit Agreement provides for a secured revolving line of credit initially up to $15.0 million (the "Revolving Credit Facility"). Availability under the Revolving Credit Facility is subject to a borrowing base calculated in accordance with the terms of the Credit Agreement and on the basis of eligible accounts and inventory and certain other reserves and adjustments. Pursuant to the Credit Agreement, the Company granted to the Agent, for itself and the Lenders, a first priority security interest in all existing and future acquired assets owned by the Company. Subject to the terms of the Credit Agreement, from time to time the Company may request that the initial revolving loan amount available under the Revolving Credit Facility be increased with additional tranches in minimum amounts of $1,000,000, up to a maximum borrowing availability of $30.0 million. The Agent and Lenders must consent to any such increase in their sole discretion. The Revolving Credit Facility matures on December 19, 2025.
Except as set forth in the Credit Agreement, borrowings under the Revolving Credit Facility bear interest at a rate equal to Term SOFR (Secured Overnight Financing Rate) plus 4.10%. The Company is required to make monthly interest payments on the Revolving Credit Facility, with the entire principal payment due at maturity.
At April 30, 2023, there was $3,548,000 outstanding under the Revolving Credit Facility, with remaining borrowing capacity under the Revolving Credit Facility of $10,286,000. The borrowing rate under the Revolving Credit Facility was 9.02% as of April 30, 2023. At April 30, 2023, the Company was in compliance with all financial covenants under its revolving credit facility. In addition, the Company's International subsidiaries have a balance outstanding of $39,000 in short-term borrowings related to overdraft protection and short-term loan arrangements.
At April 30, 2023, there were foreign bank guarantees outstanding to customers in the amounts of $5.2 million, $142,000, $3,000, and $233,000 with expiration dates in fiscal years 2024, 2025, 2026, and 2027, respectively, collateralized by certain assets of the Company's subsidiaries in India. At April 30, 2022, there were bank guarantees issued by foreign banks outstanding to customers in the amounts of $8.2 million, $111,000, $9,000, $3,000, and $249,000 with expiration dates in fiscal years 2023, 2024, 2025, 2026, and 2027, respectively, collateralized by a $6.0 million corporate guarantee and certain assets of the Company's subsidiaries in India.
