Senior Credit Facility - Revolving Facility

In 2017, we entered into a credit agreement with a group of lenders for a $3.0 billion credit facility ("Senior Credit Facility"), comprised of a $2.0 billion senior unsecured multicurrency revolving credit facility ("Revolving Facility") and an approximately $1.0 billion senior unsecured multicurrency term loan facility (the "Term Loan Facility"). The credit agreement was subsequently amended to provide an additional senior unsecured term loan in Japanese yen for approximately $424.7 million at the exchange rate effective on the transaction date. The Term Loan Facility bears interest at a rate based on LIBOR plus a margin that can vary from 1.00% to 1.70%. We are required to repay the Term Loan Facility at a rate of 5% of the original principal amount per annum with the remaining balance to be repaid in full at the maturity of the Senior Credit Facility on December 12, 2022. As of March 31, 2021 and December 31, 2020, the total amounts outstanding under the Term Loan Facility, net of debt issuance costs, were $1.2 billion and $1.3 billion, respectively.

The Revolving Facility allows us to borrow, repay and reborrow over its term. The Revolving Facility provides a sublimit for the issuance of letters of credit of up to $250.0 million at any one time. In March 2020, we borrowed a total of $250.0 million under the Revolving Facility, which was fully repaid in May 2020. As of March 31, 2021, we had 37 irrevocable letters of credit totaling $75.7 million issued and outstanding under the Revolving Facility and the amount available to us to borrow under the Revolving Facility was approximately $1.9 billion as of March 31, 2021.
