Senior Credit Facility

On November 22, 2019, the Company entered into the sixth amendment to its senior credit agreement, which provides for, among other things, (i) an increase in the aggregate commitments available under the revolving credit facility to $250.0 million and an extension of its maturity date to November 2024 and (ii) a reduction of 25 basis points in the applicable margin for the term loans. The Company wrote-off deferred loan costs totaling $18.9 million related to repayment (and retirement) of the term B loan facility due 2022 and partial repayment of the outstanding loans under the term B loan facility due 2025.

At December 31, 2019, the interest on the term B loans was 3.55 percent. Borrowings under the revolving credit facility bear interest at LIBOR plus 1.25 to 2.25 percent, or the bank’s base rate plus 0.25 to 1.25 percent, depending on leverage levels. A commitment fee of 0.20 to 0.35 percent is payable on the undrawn portion of the revolving credit facility. There are no required minimum payments for any of the Company's debt instruments until their maturity dates. The Company is required to make mandatory prepayments on its term loans from excess cash flow and with the proceeds of asset sales, debt issuances and specified other events, subject to certain exceptions. The senior credit facility is secured by substantially all of our assets and includes various restrictive covenants including the maximum ratio of consolidated secured debt to consolidated EBITDA, which steps down at regular intervals from 4.50 to 1.00 as of December 31, 2019, to 3.75 to 1.00 as of September 30, 2021. The senior credit facility also contains certain customary limitations including, among other terms and conditions, the Company's ability to incur additional indebtedness, engage in mergers and acquisitions and declare dividends. At December 31, 2019, the Company was in compliance with its debt covenants. At December 31, 2019, the ratio of consolidated debt to consolidated EBITDA was 2.30 to 1.00 and the Company had $246.1 million available borrowing capacity under its revolving credit facility.

Senior Notes

On November 22, 2019, the Company issued $550.0 million of 4.625 percent senior notes due 2028 (the "Senior Notes"). The Company used the proceeds from the Senior Notes to repay or paid down borrowings under its senior credit facility. Interest on the Senior Notes is payable in arrears on May 15 and November 15 of each year beginning on May 15, 2020. The Senior Notes are senior unsecured obligations and are effectively subordinated to the Company’s existing and future secured indebtedness (including the secured indebtedness under the Company's

senior credit agreement) to the extent of the value of the collateral securing that indebtedness and are structurally subordinated to all of the liabilities of any of the Company's subsidiaries that do not guarantee the notes. The Senior Notes also contain certain customary limitations including, among other terms and conditions, the Company's ability to incur additional indebtedness, engage in mergers and acquisitions, transfer or sell assets and make certain distributions.

In connection with the issuance of the Senior Notes and the sixth amendment to the senior credit agreement, the Company incurred $9.1 million of debt issuance and amendment costs, of which $8.6 million are presented in the consolidated balance sheet as a reduction of outstanding debt and are being amortized over the term of the Senior Notes and the term loans and $0.5 million fees were presented in other current assets and other non-current assets and are being amortized over the term of the revolving credit facility.
