Credit Facilities

Until August 3, 2016, we had a credit agreement (the “2013 Credit Agreement”), as amended, which provided for a revolving credit facility of $750.0 million (the “2013 Revolving Credit Facility”) and a term loan of $350.0 million (the “2013 Term Loan”). The 2013 Credit Agreement was effective November 25, 2013. Effective August 3, 2016, we amended and restated the 2013 Credit Agreement to provide 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. The proceeds of the 2016 Term Loan were used to repay amounts drawn under the 2013 Term Loan, as well as a portion of the outstanding balance under the 2013 Revolving Credit Facility. 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 and most of the assets of most of our subsidiaries. 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 September 30, 2016 with respect to the 2016 Credit Agreement and December 31, 2015 with respect to the 2013 Credit Agreement. 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 0.20% of the unused amount as of September 30, 2016. 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 (0.52% at September 30, 2016) 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 (3.50% at September 30, 2016), (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 rate in effect at September 30, 2016 was 1.77%. 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. We capitalized an additional $3.0 million of debt issuance costs associated with the 2016 Credit Agreement. Debt issuance costs are amortized over the life of the agreement and are included as part of interest expense. In connection with the amendment and restatement of the 2013 Credit Agreement, $0.1 million attributable to the acceleration of expense for debt issuance costs in connection with the 2013 Credit Agreement was recorded as part of interest expense during the third quarter of 2016. We are required to make principal payments on the 2016 Term Loan in installments on the last day of March, June, September and December of each year, commencing with the calendar quarter ending December 31, 2016, in the amount of $5.0 million, with a payment of all unpaid principal and interest due on August 3, 2021. As of September 30, 2016 and December 31, 2015, the balance of the 2016 Term Loan and the 2013 Term Loan was $400.0 million and $315.0 million, respectively. As of September 30, 2016 and December 31, 2015, we had approximately $115.4 million and $99.0 million of letters of credit outstanding, respectively. There were $125.0 million in borrowings outstanding under the 2016 Revolving Credit Facility as of September 30, 2016. There were no borrowings outstanding under the 2013 Revolving Credit Facility as of December 31, 2015.
