Credit Agreement

We have a credit agreement dated as of August 3, 2016, which provides for a $900.0 million revolving credit facility (the “2016 Revolving Credit Facility”) and a $400.0 million term loan (the “2016 Term Loan”) (collectively referred to as the “2016 Credit Agreement”) expiring August 3, 2021. We may increase the 2016 Revolving Credit Facility to $1.3 billion if additional lenders are identified and/or existing lenders are willing to increase their current commitments. We may allocate up to $300.0 million of available capacity under the 2016 Revolving Credit Facility to letters of credit for our account or for the account of any of our subsidiaries. Obligations under the 2016 Credit Agreement are guaranteed by most of our direct and indirect subsidiaries and are secured by substantially all of our assets. The 2016 Credit Agreement contains various covenants providing for, among other things, maintenance of certain financial ratios and certain limitations on payment of dividends, common stock repurchases, investments, acquisitions, indebtedness and capital expenditures. We were in compliance with all such covenants as of June 30, 2018 and December 31, 2017. A commitment fee is payable on the average daily unused amount of the 2016 Revolving Credit Facility, which ranges from 0.15% to 0.30%, based on certain financial tests. The fee was 0.15% of the unused amount as of June 30, 2018. Borrowings under the 2016 Credit Agreement bear interest at (1) a base rate plus a margin of 0.00% to 0.75%, based on certain financial tests, or (2) United States dollar LIBOR (2.09% and 2.33% at June 30, 2018 for our 2016 Revolving Credit Facility and our 2016 Term Loan, respectively) plus 1.00% to 1.75%, based on certain financial tests. The base rate is determined by the greater of (a) the prime commercial lending rate announced by Bank of Montreal from time to time (5.00% at June 30, 2018), (b) the federal funds effective rate, plus ½ of 1.00%, (c) the daily one month LIBOR rate, plus 1.00%, or (d) 0.00%. The interest rates in effect at June 30, 2018 were 3.09% and 3.33% for our 2016 Revolving Credit Facility and our 2016 Term Loan, respectively. Fees for letters of credit issued under the 2016 Revolving Credit Facility range from 1.00% to 1.75% of the respective face amounts of outstanding letters of credit and are computed based on certain financial tests. Debt issuance costs are amortized over the life of the agreement and are included as part of interest expense. The 2016 Term Loan previously required us to make principal payments of $5.0 million on the last day of March, June, September and December of each year, which commenced with the calendar quarter ended December 31, 2016. On December 30, 2016, we made a payment of $100.0 million, of which $5.0 million represented our required quarterly payment and $95.0 million represented a prepayment of outstanding principal. Such prepayment was applied against the remaining mandatory quarterly payments on a ratable basis. As a result, commencing with the calendar quarter ended March 31, 2017, our required quarterly payment has been reduced to $3.8 million. All unpaid principal and interest is due on August 3, 2021. As of June 30, 2018 and December 31, 2017, the balance of the 2016 Term Loan was $277.2 million and $284.8 million, respectively. As of June 30, 2018 and December 31, 2017, we had approximately $110.3 million and $110.1 million of letters of credit outstanding, respectively. There were $25.0 million in borrowings outstanding under the 2016 Revolving Credit Facility as of June 30, 2018 and December 31, 2017.
