SENIOR SECURED CREDIT FACILITIES In 2017, Holdings and American Axle & Manufacturing, Inc. (AAM Inc.) entered into a credit agreement (the Credit Agreement). In connection with the Credit Agreement, Holdings, AAM, Inc. and certain of their restricted subsidiaries entered into a Collateral Agreement and Guarantee Agreement with the financial institutions party thereto. The Credit Agreement included a $100.0 million term loan A facility (the Term Loan A Facility), a $1.55 billion term loan B facility (the Term Loan B Facility) and a $932 million multi-currency revolving credit facility (the Revolving Credit Facility, and together with the Term Loan A Facility and the Term Loan B Facility, the Senior Secured Credit Facilities).

In July 2019, Holdings, AAM, Inc., and certain subsidiaries of Holdings entered into the First Amendment to the Credit Agreement (as amended by the First Amendment, the Amended Credit Agreement). The First Amendment, among other things, established $340 million in incremental term loan A commitments under the Amended Credit Agreement with a maturity date of July 29, 2024 (Term Loan A Facility due 2024), reduced the availability under the Revolving Credit Facility from $932 million to $925 million and extended the maturity date of the Revolving Credit Facility from April 6, 2022 to July 29, 2024, and modified the applicable margin with respect to interest rates under the Term Loan A Facility due 2024 and interest rates and commitment fees under the Revolving Credit Facility. The applicable margin and the maturity date for the Term Loan B Facility remain unchanged. The proceeds of $340 million were used to repay all of the outstanding loans under the existing Term Loan A Facility and a portion of the outstanding Term Loan B Facility, resulting in no additional indebtedness. This also satisfied all payment requirements under the Term Loan B Facility until maturity in 2024. We expensed $5.1 million for the write-off of the unamortized debt issuance costs related to the existing Term Loan A Facility and a portion of the unamortized debt issuance costs related to our Term Loan B Facility that we had been amortizing over the expected life of the borrowings.

In December 2019, we used a portion of the cash proceeds from the sale of the U.S. operations of our Casting segment (the Casting Sale) to make a payment on our Term Loan B Facility, which included a principal payment of $59.8 million and $0.4 million in accrued interest. We also expensed approximately $1.0 million for the write-off of the unamortized debt issuance costs that we had been amortizing over the expected life of the borrowing.

In April 2020, Holdings, AAM, Inc., and certain subsidiaries of Holdings entered into the Second Amendment to the Credit Agreement (Second Amendment). For the period from April 1, 2020 through March 31, 2022 (the Amendment Period), the Second Amendment, among other things, replaced the total net leverage ratio covenant with a new senior secured net leverage ratio covenant, reduced the minimum levels of the cash interest expense coverage ratio covenant, and modified certain covenants restricting the ability of Holdings, AAM and certain subsidiaries of Holdings to create, incur, assume or permit to exist certain additional indebtedness and liens and to make certain restricted payments, voluntary payments and distributions. The Second Amendment also increased the maximum levels of the total net leverage ratio covenant after the Amendment Period, modified the applicable margin with respect to interest rates under the Term Loan A Facility due 2024 and interest rates and commitment fees under the Revolving Credit Facility, and increased the minimum adjusted London Interbank Offered Rate for Eurodollar-based loans under the Term Loan A Facility due 2024 and Revolving Credit Facility. The applicable margin for the Term Loan B Facility remains unchanged. We paid debt issuance costs of $4.6 million in the year ended December 31, 2020 related to the Second Amendment.

In December 2020, we made a voluntary prepayment of $100 million on our Term Loan B Facility and paid approximately $15 million on our Term Loan A Facility due 2024, which included approximately $12.8 million for the prepayment of all required payments under the Term Loan A Facility due 2024 for 2021. As a result, we expensed approximately $1.2 million for the write-off of the unamortized debt issuance costs that we had been amortizing over the life of these borrowings.

At December 31, 2020, $891.2 million was available under the Revolving Credit Facility. This availability reflects a reduction of $33.8 million for standby letters of credit issued against the facility. The proceeds of the Revolving Credit Facility are used for general corporate purposes.

The Senior Secured Credit Facilities provide back-up liquidity for our foreign credit facilities. We intend to use the availability of long-term financing under the Senior Secured Credit Facilities to refinance any current maturities related to such debt agreements that are not otherwise refinanced on a long-term basis in their local markets, except where otherwise reclassified to Current portion of long-term debt on our Consolidated Balance Sheet.

6.875% NOTES DUE 2028 In the second quarter of 2020, we issued $400 million in aggregate principal amount of 6.875% senior notes due 2028 (the 6.875% Notes). Proceeds from the 6.875% Notes were used primarily to fund the redemption of the remaining $350 million of 6.625% senior notes due 2022 described below and for general corporate purposes. We paid debt issuance costs of $6.4 million in the year ended December 31, 2020 related to the 6.875% Notes.

REDEMPTION OF 6.625% NOTES DUE 2022 In the first quarter of 2020, we voluntarily redeemed a portion of our 6.625% Notes due 2022.

Proceeds from the 6.25% Notes due 2026 were used primarily to fund the tender offer for the 6.25% senior notes due 2021 (the 6.25% Notes due 2021) described below. We paid debt issuance costs of $6.6 million during 2018 related to the 6.25% Notes due 2026.

TENDER OFFER OF 6.25% NOTES DUE 2021 Also during the first quarter of 2018, we made a tender offer for our 6.25% Notes due 2021.

FOREIGN CREDIT FACILITIES We utilize local currency credit facilities to finance the operations of certain foreign subsidiaries. These credit facilities, some of which are guaranteed by Holdings and/or AAM, Inc., expire at various dates through May 2023.
