Xiamen Project Loans In November 2018, PDMCX obtained approval to borrow 345 million RMB from the Industrial and Commercial Bank of China. From November 2018 through July 2020, PDMCX entered into separate loan agreements (the “Project Loans”) for the entire approved amount and, as of October 31, 2022, 56.4 million RMB ($7.7 million) remained outstanding. The Project Loans were used to finance certain capital expenditures at the PDMCX facility, and are collateralized by liens granted on the land use right, building, and certain equipment located at the facility. The interest rates on the Project Loans are variable (based on the RMB Loan Prime Rate of the National Interbank Funding Center), and interest incurred on the loans was eligible for reimbursement through incentives provided by the Xiamen Torch Hi-Tech Industrial Development Zone, which afforded for such reimbursements up to a prescribed limit and duration. The Project Loans are subject to covenants and provisions, certain of which relate to the assets pledged as security for the loan, all of which we were in compliance with at October 31, 2022. Xiamen Working Capital Loans In November 2018, PDMCX obtained approval for revolving, unsecured credit of the equivalent of $25.0 million, pursuant to which PDMCX may enter into separate loan agreements with varying terms to maturity. This facility is subject to annual reviews and extension. Unless extended, this facility will expire in November 2023. As of October 31, 2022, PDMCX had 25.6 million RMB ($3.5 million) outstanding against the approval. The interest rates are variable, based on the RMB Loan Prime Rate of the National Interbank Funding Center. Interest incurred on the loans is eligible for reimbursement through incentives provided by the Xiamen Torch Hi-Tech Industrial Development Zone, which provide for such reimbursements up to a prescribed limit and duration. Hefei Equipment Loan In October 2020, our Hefei, China, facility was approved to borrow 200 million RMB from the China Construction Bank Corporation. In July 2022, we repaid our entire outstanding balance of 120.7 million RMB ($18.0 million). This credit facility was subject to annual reviews and extension; the most recent extension expired in August 2022 and we did not apply for an extension. The loan proceeds were used to fund purchases of two lithography tools at the Hefei facility. The interest rate on the loan was variable and based on the RMB Loan Prime Rate of the National Interbank Funding Center. The borrowings were secured by the Hefei facility, its related land use right, and certain manufacturing equipment. The Hefei Equipment Loan was subject to covenants and provisions, certain of which relate to the assets pledged as security for the loan, including covenants for the ratio of total liabilities to total assets and the ratio of current assets to current liabilities, all of which we were in compliance with at the time of repayment. Finance Leases In February 2021, under an MLA which we entered into effective October 2020, we entered into a five-year $7.2 million finance lease for a high-end inspection tool and, in December 2020, under an MLA which we entered into effective July 2019, we entered into a $35.5 million lease for a high-end lithography tool. See Note 8 for additional information on these leases. Corporate Credit Agreement In September 2018, we entered into a five-year amended and restated credit agreement (the “Credit Agreement”), which has a $50 million borrowing limit, with an expansion capacity to $100 million. The Credit Agreement is secured by substantially all of our assets located in the United States and certain of the common stock we own in certain foreign subsidiaries. The Credit Agreement includes covenants around minimum interest coverage ratio, total leverage ratio, and minimum unrestricted cash balance (all of which we were in compliance with at October 31, 2022), and limits the amount of cash dividends, distributions, and redemptions we can pay on our common stock to an aggregate annual amount of $50 million. We had no outstanding borrowings against the Credit Agreement at October 31, 2022. The interest rate on the Credit Agreement (4.75% at October 31, 2022) is based on our total leverage ratio at LIBOR plus a spread, as defined in the Credit Agreement. Interest Paid for Debt Interest payments, including capitalized interest of $0.1 million in both 2021 and 2020, were $2.8 million in 2022, $3.8 million in 2021, and $2.6 million in 2020.
