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 on August 5, 2016, resulting in a 25 basis points reduction 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 facility was also amended on February 21, 2017, resulting in a 50 basis points reduction in the interest rate for the term B loan facility and an increase in the borrowing capacity of the revolving credit facility from $150.0 million to $200.0 million, with the maturity date for the revolving credit facility extended from June 5, 2020 to February 21, 2022. The maturity date for the term B loan remained at June 5, 2022. The Company incurred $2.5 million in third-party fees, of which $1.9 million were included in interest expense in the six months ended June 30, 2017. The remaining fees were included in other current assets and other non-current assets and will be amortized over the term of the revolving credit facility.

Borrowings under the term B loan bear interest at LIBOR, plus 2.25 percent and borrowings under the revolving credit facility bear interest at LIBOR (or the bank’s base rate), plus 0.75 to 2.5 percent depending on leverage levels. A commitment fee of 0.25 to 0.40 percent is payable on the undrawn portion of the revolving credit facility. At June 30, 2017, the interest rate on the term B loan was 3.5 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 June 30, 2017, no additional minimum quarterly payments are required.

The Company's obligations under the credit facility are guaranteed by substantially all of its direct and indirect domestic subsidiaries and are secured by a lien on substantially all of the Company's tangible and intangible property and by a pledge of all of the equity interests in its direct and indirect domestic subsidiaries.

The credit facility includes various restrictive covenants including the maximum ratio of consolidated funded debt to consolidated EBITDA (4.00 to 1.00 as of June 30, 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 June 30, 2017, the Company had a ratio of consolidated funded debt to consolidated EBITDA of 2.04 to 1.00.

At June 30, 2017 the Company was in compliance with all of its debt covenants and had $196.0 million of borrowing available under the revolving credit facility, after excluding the unused stand-by letters of credit of $4.0 million at June 30, 2017.
