Interest rates on certain notes are subject to adjustment based on changes in our credit ratings.

In February 2020, we secured a five-year $850 million term loan scheduled to mature January 2025 (the 2025 Term Loan). The 2025 Term Loan bears interest at LIBOR plus 5.5% and resets monthly.

In March 2020, we purchased under a tender offer $428 million of the October 2021 notes, $250 million of the May 2022 notes, $125 million of the April 2023 notes and $125 million of the March 2024 notes. A $37 million loss was incurred on the early redemption of debt and is recorded in other expense. During the first quarter of 2020, we repaid $5 million of principal related to our term loans.

We have a $500 million secured revolving credit facility that expires in November 2024 and contains financial and non-financial covenants. Through March 31, 2020 we had not drawn upon the credit facility; however in light of the current macroeconomic environment, we drew down $100 million under the credit facility as a precautionary measure in April. At March 31, 2020, we were in compliance with all covenants.
