On October 29, 2018, the Company entered into a JPY 33.0 billion Term Loan Agreement (the “TOKIN Term Loan Facility”) by and among TOKIN Corporation (“TOKIN”), the lenders party thereto (the “Lenders”) and Sumitomo Mitsui Trust Bank, Limited in its capacity as agent (the “Agent”), arranger and Lender. Funding for the TOKIN Term Loan Facility occurred on November 7, 2018. The proceeds, which were net of an arrangement fee withheld from the funding amount, were JPY 32.1 billion, or approximately $283.9 million using the exchange rate as of November 7, 2018. Net of the arrangement fee, bank issuance costs, and other indirect issuance costs, the Company's net proceeds from the TOKIN Term Loan Facility were $281.8 million.

The TOKIN Term Loan Facility consists of (i) a JPY 16.5 billion (approximately $146.0 million using the exchange rate as of November 7, 2018) Term Loan A tranche (the “Term Loan A”) and (ii) a JPY 16.5 billion (approximately $146.0 million using the exchange rate as of November 7, 2018) Term Loan B tranche (the “Term Loan B” and, together with the Term Loan A, collectively, the “Term Loans”). Principal payments under Term Loan A are required semi-annually, in the amount of JPY 1.4 billion (approximately $12.7 million using the exchange rate as of September 30, 2019), while the principal of Term Loan B is due in one payment at maturity. At each reporting period, the carrying value of the loan is translated from Japanese Yen to U.S. Dollars using the spot exchange rate as of the end of the reporting period.

Interest payments are due semi-annually on the Term Loans, with the interest rate based on a margin over the six-month Japanese TIBOR. The applicable margin for Term Loan A is 2.00% and for Term Loan B is 2.25%. Japanese TIBOR at September 30, 2019 was 0.13%.

The Term Loans mature on September 30, 2024. KEMET Corporation and certain subsidiaries of TOKIN provided guarantees of the obligations under the Term Loans, which also are secured by certain assets, properties and equity interests of TOKIN and its material subsidiaries. The Term Loans contain customary covenants applicable to both the Company and to TOKIN, including maintenance of a consolidated leverage ratio, the absence of two consecutive years of consolidated operating losses and the maintenance of certain required levels of consolidated net assets. The TOKIN Term Loan Facility agreement also contains customary events of default. The Company may prepay the Term Loans at any time, subject to certain notice requirements and reimbursement of loan breakage costs.

In connection with the closing of the TOKIN Term Loan Facility on October 29, 2018, the Company entered into Amendment No. 10 to the Loan and Security Agreement, Waiver and Consent (the “Revolver Amendment”), by and among KEMET Corporation, KEMET Electronics Corporation (“KEC”), the other borrowers named therein, the financial institutions party thereto as lenders and Bank of America, N.A., a national banking association, as agent for the lenders. The Revolver Amendment provides the Company with, among other things, increased flexibility for certain restricted payments (including dividends), and also released certain pledges that allowed the Company to obtain the TOKIN Term Loan Facility in order to pay in full the Company's prior term loan. The revolving line of credit has a facility amount of up to $75.0 million, which is based on factors including outstanding eligible accounts receivable, inventory, and equipment collateral. There were no borrowings under the revolving line of credit during the quarter ended September 30, 2019, and the Company’s available borrowing capacity under the revolving line of credit was $60.1 million as of September 30, 2019.

In September, November, and February of fiscal year 2019, the Company entered into three agreements with different customers (the “Customers”) pursuant to which the Customers agreed to make advances (collectively, the “Advances”) to the Company in an aggregate amount of up to $72.0 million (collectively, the “Customer Capacity Agreements”). The Company is using these Advances to fund the purchase of production equipment and to make other investments and improvements in its business and operations (the “Investments”) to increase overall capacity to produce various electronic components of the type and part as may be sold by the Company to the Customers from time to time. The Company retains all rights to the production equipment purchased with the funds from the Advances. The Advances from the Customers are being made in quarterly installments over an expected period of 18 to 24 months from the effective date of the respective Customer Capacity Agreements.

The Advances will be repaid beginning on the date that production from the Investments is sufficient to meet the Company's obligations under the agreements with the Customers. Repayments will be made on a quarterly basis as determined by calculations that generally consider the number of components purchased by the Customers during the quarter. Repayments based on the calculations will continue until either the Advances are repaid in full, or December 31, 2038 for all three Customers. The Company has a quarterly repayment cap in the agreement with each of the Customers and is not required to make any quarterly repayments to the Customers that in the aggregate exceeds $1.8 million. If the Customers do not purchase a number of components that would require full repayment of the Advances by December 31, 2038, then the Advances shall be deemed repaid in full. Additionally, if the Customers do not purchase a number of components that would require a payment on the Advances for a period of 16 consecutive quarters, the Advances shall be deemed repaid in full.

As of September 30, 2019, the Company has received a total of $35.0 million in Advances. Since the debt is non-interest bearing, the Company has recorded debt discounts on the Advances. These discounts will be amortized over the expected life of the Advances through interest expense. During the six months ended September 30, 2019, the Company had $19.9 million in capital expenditures related to the Customer Capacity Agreements.

As of September 30, 2019, the Company had $0.6 million in cash that was restricted to be used to fund these Investments. Restricted cash is recorded within “Prepaid expenses and other current assets” in the Condensed Consolidated Balance Sheets.

In January 2017, KEMET Electronics Portugal, S.A. (“KEP”), a wholly owned subsidiary, entered into a program with the Portuguese government where KEP is eligible to receive interest free loans if purchases of fixed assets meet certain approved terms within the program. In January 2017, KEP received the first part of an interest free loan in the amount of EUR 2.2 million (or $2.5 million). In July 2017, KEP received the second part of the loan in the amount of EUR 0.3 million (or $0.3 million). The loan has a maturity date of February 1, 2025. The loan is being repaid through semi-annual payments on August 1 and February 1 of each year. Repayments started in August 2019 and are in the amount of EUR 0.2 million (or $0.2 million).

In February 2019, KEP received a second interest free loan from the Portuguese government in the amount of EUR 0.9 million (or $1.1 million). The loan has a maturity date of September 1, 2026 and will be repaid through semi-annual payments on March 1 and September 1 of each year beginning on March 1, 2021. The repayments will be in the amount of EUR 0.1 million (or $0.1 million).

Since the KEP debt is non-interest bearing, the Company has recorded debt discounts on these loans. These discounts are being amortized over the life of the loans through interest expense. If certain conditions are met by KEP, such as increased headcount at its facility in Evora, Portugal, increased revenue, and increased gross value added, a portion of these loans could be forgiven.

TOKIN has a short term borrowing pursuant to an agreement with The 77 Bank Limited, located in Japan, in the amount of 350.0 million Yen (or $3.2 million), at an interest rate of 0.53% (Japanese TIBOR plus 40 basis points). The loan was originally due in September 2019 and was extended to September 2020. The loan agreement automatically renews for successive one year periods if both parties choose not to terminate or modify it.
