Credit Agreement Covenant Compliance
The Credit Agreement contains various provisions and covenants, including, among other items, restrictions on the ability to pay dividends, incur additional indebtedness and issue certain capital stock. We have agreed to maintain certain financial ratios, including interest coverage and total net leverage ratios, all as defined in the Credit Agreement. Among other things, it will be an event of default if our total net leverage ratio or interest coverage ratio as of the end of any fiscal quarter is greater than 5.25:1.00 or less than 2.25:1.00, respectively. As of June 30, 2020, our total net leverage ratio under the Credit Agreement was 4.22:1.00, and our interest coverage ratio was 3.84:1.00. As of June 30, 2020, we were in compliance with the Credit Agreement covenants.
6.50% Senior Notes due 2022
In September 2014, we completed an offering of $200.0 million aggregate principal amount of 6.50% Senior Notes due in October 2022 (the “Existing Notes”). The Existing Notes were priced at par, which resulted in total gross proceeds of $200.0 million. On June 8, 2015, we completed an additional offering of $300.0 million in aggregate principal amount of 6.50% Senior Notes due 2022 (the “New Notes” and together with the Existing Notes, the “Senior Notes”). The New Notes were issued as additional notes under the same indenture pursuant to which the Existing Notes were previously issued on in September 2014. The New Notes were priced at 98.26% of par with a yield to maturity of 6.80% and resulted in total gross proceeds of approximately $294.8 million, excluding accrued interest. The discount is being amortized using the effective interest method over the term of the notes.
The Senior Notes mature on October 1, 2022 and interest is payable semi-annually on April 1 and October 1 of each year. Consolidated Communications, Inc. (“CCI”) is the primary obligor under the Senior Notes, and we and a majority of our wholly-owned subsidiaries have fully and unconditionally guaranteed the Senior Notes. The Senior Notes are senior unsecured obligations of the Company.
During the six months ended June 30, 2020 and 2019, we repurchased $4.5 million and $4.6 million, respectively, of the aggregate principal amount of the Senior Notes. In connection with the partial repurchase of the Senior Notes, we paid $4.2 million and $4.3 million and recognized a gain on extinguishment of debt of $0.2 million and $0.3 million, respectively, during the six months ended June 30, 2020 and 2019.
