In October 2014, we entered into a new credit agreement (the "Credit Agreement") with a group of banks. The Credit Agreement provides for a $300 million three-year delayed-draw term loan (the "Term Loan Facility") and a $500 million five-year revolving credit facility (the "Revolving Credit Facility"). The Credit Agreement replaced a prior credit agreement that was scheduled to mature on January 6, 2017. Subject to certain conditions, the aggregate commitments under the Revolving Credit Facility may be increased by up to $300 million at any time upon agreement between us and existing or additional lenders. Borrowings under the Revolving Credit Facility and the Term Loan Facility may be used for general corporate purposes. Simultaneously with the execution of the Credit Agreement and pursuant to its terms, we repaid all amounts outstanding under, and terminated, the prior credit agreement.

The Term Loan Facility is scheduled to mature on October 27, 2017. The Revolving Credit Facility is scheduled to mature on October 25, 2019. Borrowings under the Credit Agreement bear interest at an Adjusted Base Rate or the Eurodollar Rate (both as defined in the Credit Agreement), at our option, plus an applicable margin to be initially based on our Leverage Ratio (as defined in the Credit Agreement) and, at our election, based on the ratings of our senior unsecured debt by both Moody’s Investors Service, Inc. and Standard & Poor’s Ratings Services, thereafter to be based on such debt ratings. The applicable margin varies: (1) in the case of advances bearing interest at the Adjusted Base Rate, from 0.125% to 0.750% for borrowings under the Revolving Credit Facility and from 0% to 0.500% for borrowings under the Term Loan Facility; and (2) in the case of advances bearing interest at the Eurodollar Rate, from 1.125% to 1.750% for borrowings under the Revolving Credit Facility and from 1.000% to 1.500% for borrowings under the Term Loan Facility. The Adjusted Base Rate is the highest of (1) the per annum rate established by the administrative agent as its prime rate, (2) the federal funds rate plus 0.50% and (3) daily one-month LIBOR plus 1%. We pay a commitment fee ranging from 0.125% to 0.300% on the unused portions of the Revolving Credit Facility and the Term Loan Facility, depending on our Leverage Ratio. The commitment fees are included as interest expense in our consolidated financial statements.

The Credit Agreement contains various covenants that we believe are customary for agreements of this nature, including, but not limited to, restrictions on our ability and the ability of each of our subsidiaries to incur debt, grant liens, make certain investments, make distributions, merge or consolidate, sell assets, enter into transactions with affiliates and enter into certain restrictive agreements. We are also subject to a maximum Leverage Ratio of 4.00 to 1.00. The Credit Agreement includes customary events of default and associated remedies. As of March 31, 2015 and December 31, 2014, we were in compliance with all the covenants set forth in the Credit Agreement.

In November 2014, we completed the public offering of $500 million aggregate principal amount of 4.650% Senior Notes due 2024 (the "Senior Notes"). We will pay interest on the Senior Notes on May 15 and November 15 of each year, beginning on May 15, 2015. The Senior Notes are scheduled to mature on November 15, 2024. We may redeem some or all of the Senior Notes at specified redemption prices. We used the net proceeds from the offering for general corporate purposes, including funding acquisitions and capital expenditures and repurchases of shares of our common stock.

We incurred $6.9 million of issuance costs related to the Senior Notes and $1.6 million of new loan costs related to the Revolving Credit Facility and the Term Loan Facility. We are amortizing these costs, which are included on our balance sheet as other non-current assets, to interest expense over ten years for the Senior Notes and over five years for the Revolving Credit Facility and the Term Loan Facility.
