On June 20, 2017, the Company entered into a Sixth Amended and Restated Credit Agreement (the "restated credit agreement") as part of refinancing its prior credit agreement. On that day, the Company used an initial draw of $230 million to pay off the outstanding $225 million term and revolving loan balances, with interest, along with $4.0 million in fees related to the restated credit agreement. The fees are being amortized over the term of the agreement.

The Company's restated credit agreement provides for (1) revolving credit facility borrowings consisting of revolving loans, letters of credit participation, and swing-line loans (the “revolving loans”) in an aggregate amount of $600 million and (2) a provision allowing the Company to request an increase of the aggregate amount of the revolving loans in an amount not to exceed $150 million. The restated credit agreement is secured by the accounts receivable of the Company and its domestic subsidiaries, as well as by the outstanding stock of certain subsidiaries of the Company. The restated credit agreement contains customary representations, warranties, affirmative and negative covenants, and default and acceleration provisions. The restated credit agreement matures, and is fully due and payable, on June 20, 2022 and allows for prepayments before maturity.

The revolving loan borrowings bear interest at LIBOR or at an alternative base rate plus a credit spread. At December 31, 2017, the revolving loan borrowing bears interest at LIBOR plus a credit spread of 2%. The weighted-average interest rate on revolving credit borrowings at December 31, 2017 was 3.6%. There were no material outstanding letters of credit at December 31, 2017 or March 31, 2017.

Under the terms of the restated credit agreement, the Company is required to maintain certain debt-to-cash flow and interest coverage ratios, among other restrictions. At December 31, 2017, the Company was in compliance with these covenants and restrictions.
