Note 7 – Long term debt

In connection with the purchase of our new facility in November 2018, a wholly-owned subsidiary (the “mortgagor subsidiary”) of the Company entered into a Fee Mortgage and Security Agreement (the “mortgage agreement”) with Citibank, N.A. (the “mortgagee”). The mortgage agreement provides for a loan of $4,500 for a term of 10 years, bears a fixed interest rate of 5.09% per annum and requires monthly mortgage payments of principal and interest of $30. Debt issuance costs of $72 are being amortized over the life of the mortgage agreement. The balance of unamortized debt issuance cost was $48 at April 30, 2022. At April 30, 2022, the balance owed by the subsidiary under the mortgage agreement was $4.0 million. The Company’s obligations under the mortgage agreement are secured by the new facility and by a $1,000 cash collateral deposit with the mortgagee as additional security. This restricted cash is included in other assets as of April 30, 2022.

The mortgage agreement includes affirmative and negative covenants and events of default, as defined. Events of default include non-payment of principal and interest on debt outstanding, non-performance of covenants, material changes in business, breach of representations, bankruptcy or insolvency, and changes in control. The mortgage includes certain financial covenants. Effective October 2020, the Company and the mortgagee agreed to a covenant restructure whereby the mortgagee waived the Company’s financial ratio covenant for the fiscal period ended July 31, 2020 and modified the mortgage to replace a financial ratio covenant with a liquidity covenant. That liquidity covenant required that we own and maintain at all times and throughout the remaining term of the loan at least $25,000 of liquid assets, defined as time deposits, money market accounts and obligations issued by the U.S. government or any of its agencies. The cash collateral agreement was also modified to require compliance with the liquidity covenant for two consecutive fiscal years before the collateral is released back to us. Effective September 29, 2021, the Company and the mortgagee agreed to further covenant restructuring whereby (a) the liquidity covenant was reduced to 150% (or approximately $6 million at April 30, 2022) of the loan principal from $25 million previously, and (b) the collateral requirement would be increased from $0.75 million to $1.0 million. The Company increased the collateral deposit to $1.0 million in November 2021 and was in compliance as to the liquidity covenant as of April 30, 2022.

In April 2020, our subsidiary in Switzerland received a loan of CHF 400 ($400, based on the foreign exchange rate as of April 30, 2022) from the Swiss government under the “Corona Krise” emergency loan program in response to the pandemic. This loan is uncollateralized, bears 0% interest, is due in 5 years, and may be repaid at any time. This loan is included in long term debt – net as of April 30, 2022.

Minimum future annual principal payments under these agreements as of April 30, 2022 are as follows:
