¹We have the intent and ability to refinance the principal payments due within the next 12 months on a long-term basis through our revolving credit facility. As such, all debt presented in the table above is classified as long-term on our March 31, 2020 Condensed Consolidated Balance Sheet.

On January 9, 2020, we completed a private placement offering of $1.0 billion aggregate principal amount of senior unsecured notes bearing an interest rate of 4.625% which are due in March 2028.

On February 11, 2020 we used the net proceeds from the $1.0 billion senior notes to repay the remaining $310.0 million of unsecured notes bearing fixed rate interest of 5.125%, which were due in July 2020 and $650.0 million of unsecured notes bearing fixed rate interest of 6.375%, which were due in October 2023. We incurred $13.8 million of early redemption fees in relation to the 2023 debt payoff. Additionally, we wrote off $7.9 million of unamortized financing fees and discounts related to the early payoff of the 2020 and 2023 notes. These charges were recorded in the other non-operating items, net line item of the Statement of Income.

As of March 31, 2020, we had unused borrowing capacity of $720.8 million under our $1.51 billion revolving credit facility (which expires August 2024) and we were in compliance with all covenants, including the leverage ratio (our one financial covenant) contained in our debt agreements and revolving credit facility. We believe that we will remain compliant with all covenants for the foreseeable future.
