As of December 31, 2018, the Company, together with certain direct and indirect subsidiaries, had a credit agreement (the “Credit Agreement”) which included a revolving credit note (“U.S. Revolving Note”) with a maximum borrowing capacity of $350,000.

On June 27, 2019, the Company entered into an Amended and Restated Credit Agreement (the “Amended Credit Agreement”) with a consortium of lenders and Bank of America, N.A. as administrative agent. The Amended Credit Agreement amends and restates in its entirety the Credit Agreement. The outstanding principal and interest of the U.S. Revolving Note under the Credit Agreement continued and constitute obligations under the Amended Credit Agreement.

The Amended Credit Agreement increased the U.S. Revolving Note from $350,000 to $475,000 and extended the maturity from March 17, 2021 to June 27, 2024. Subject to specified conditions, the Company can increase the U.S. Revolving Note or incur secured term loans in an aggregate amount of $175,000.

The U.S. borrowers and guarantors participating in the Amended Credit Agreement have entered into a related amended and restated pledge and security agreement. The amended and restated security agreement grants a security interest to the lenders in substantially all of the personal property of the Company and its U.S. subsidiaries designated as borrowers to secure their respective obligations under the Amended Credit Agreement, including the stock and membership interests of specified subsidiaries (limited to 66% of the stock in the case of certain non-U.S. subsidiaries). In addition to the security obligations, all obligations under the Amended Credit Agreement are unconditionally guaranteed by certain of the Company’s subsidiaries. The Amended Credit Agreement restricts the amount of dividend payments the Company can make to shareholders.

The Amended Credit Agreement requires the Company and its subsidiaries to comply with customary affirmative and negative covenants, and contain customary events of default. The Amended Credit Agreement also requires the Company to maintain a minimum Consolidated Interest Coverage Ratio and Consolidated Leverage Ratio, as defined in the agreement.

Under the Amended Credit Agreement, U.S. Dollar denominated loans bear interest at either a base rate (“Base Rate Loans”) or Eurocurrency rate (“Eurocurrency Rate Loans”), plus a margin (“Applicable Rate”). The rate for Base Rate Loans is equal to the highest of the Federal Funds Rate (1.90% at September 30, 2019) plus 0.50%, Bank of America’s prime rate (5.00% at September 30, 2019), or the Eurocurrency rate (0.00% at September 30, 2019) plus 1.00%. The rate for Eurocurrency Rate Loans denominated in U.S. Dollars is equal to the London Interbank Offered Rate (2.02% at September 30, 2019). All loans denominated in a currency other than the U.S. Dollar must be Eurocurrency Rate Loans. Interest is payable at least quarterly.

The Applicable Rate varies based on the Consolidated Leverage Ratio reported by the Company. As long as the Company is not in default of the terms and conditions of the Amended Credit Agreement, the lowest and highest possible Applicable Rate is 1.25% and 2.25%, respectively, for Eurocurrency Rate Loans and 0.25% and 1.25%, respectively, for Base Rate Loans.

In connection with the Amended Credit Agreement, the Company incurred debt issuance costs of $1,278 which have been capitalized and will be amortized into interest expense over the term of the credit facility.

The Company also has two fixed interest rate loans with the German Investment Corporation (“DEG”), a subsidiary of KfW Banking Group, a Germany government-owned development bank.

The first DEG loan, a loan we used to fund capital investments in China (the “DEG China Loan”), was subject to semi-annual principal payments that began March 2015 and ended in September 2019. During the third quarter of 2019, the DEG China Loan was paid in full.

The Company’s second fixed interest rate loan agreement with DEG was used to finance the construction and set up of the Vietnam production facility (“DEG Vietnam Loan”). The DEG Vietnam Loan is subject to semi-annual principal payments that began November 2017 and will end May 2023. Under the terms of the DEG Vietnam Loan, the Company must maintain a minimum Equity Ratio and Enhanced Equity Ratio, as defined by the DEG Vietnam Loan agreement, based on the financial statements of Gentherm’s wholly owned subsidiary, Gentherm Vietnam Co. Ltd.

Undrawn borrowing capacity under the U.S. Revolving Note was $385,129 as of September 30, 2019. The following table summarizes the Company’s debt as of September 30, 2019 and December 31, 2018:
