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 June 30, 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 Consolidated Statement of Income.

Given the unpredictability of market conditions during the pandemic, we amended our revolving credit facility on June 11, 2020 to extend the initial step-down of the maximum permitted total leverage ratio (from 5.50 to 1.00 to 5.25 to 1.00) until the fiscal quarter ending March 31, 2022, with additional step downs continuing thereafter. The maximum permitted total leverage ratios under our revolving credit facility are now as follows:



Period	Leverage Ratio
Fiscal quarter ending September 30, 2020 through and including fiscal quarter ending December 31, 2021	5.50 to 1.00
Fiscal quarter ending March 31, 2022	5.25 to 1.00
Fiscal quarter ending June 30, 2022	5.00 to 1.00
Fiscal quarter ending September 30, 2022	4.75 to 1.00
Thereafter	4.50 to 1.00

As of June 30, 2020, cash and cash equivalents totaled $173.1 million and we had unused borrowing capacity of $653.8 million under our $1.51 billion revolving credit facility (which expires August 2024). 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.
