In 2015, the Company entered into a $975.0 million credit facility consisting of (i) an $825.0 million seven-year term B loan facility and (ii) a $150.0 million revolving credit facility. The facility was amended four separate times. The first amendment was on August 5, 2016, resulting in a reduction of 25 basis points in the interest rate for the term B loan facility and the Company incurred $0.9 million in third-party fees, which were included in interest expense in 2016. The second amendment was on February 21, 2017, which resulted in (i) a reduction of 50 basis points in the interest rate for the term B loan facility, (ii) an increase in the borrowing capacity of the revolving credit facility from $150.0 million to $200.0 million and (iii) extension of the maturity date for the revolving credit facility to February 21, 2022. The third amendment was on August 22, 2017, which resulted in a reduction of 25 basis points in the interest rate for the term B loan facility. The fourth amendment was on September 22, 2017, which resulted in (i) a reduction of 25 to 50 basis points in the interest rate on the revolving credit facility, depending on leverage levels and (ii) a reduction of five basis points on the commitment fee for the undrawn portion. Related to the 2017 amendments the Company incurred $3.3 million in third-party fees, of which $2.7 million was included in interest expense and the remainder was capitalized and will be amortized over the term of the revolving credit facility. Borrowings under the term B loan bear interest at LIBOR plus 2.00 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. At December 31, 2017, the interest rate on the term B loan was 3.6 percent and there were no borrowings under the revolving credit facility. Under terms of the credit facility, the Company is required to make minimum quarterly payments of $2.1 million and mandatory prepayments from excess cash flow and with the proceeds of asset sales, debt issuances and specified other events, subject to specified exceptions. Due to principal payments made through December 31, 2017, no additional minimum quarterly payments are required. The credit facility includes various restrictive covenants including the maximum ratio of consolidated funded debt to consolidated earnings before interest, taxes, depreciation and amortization ("EBITDA") (4.00 to 1.00 as of December 31, 2017, and steps down at regular intervals to 3.25 to 1.00 on March 31, 2019). The 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, 2017 the Company was in compliance with its debt covenants; its ratio of consolidated funded debt to consolidated EBITDA was 1.89 to 1.00, and it had $195.6 million available borrowing capacity under its revolving credit facility.
