In October 2013, the Company issued $600.0 million of fixed-rate unsecured senior notes (the "2013 Notes") due October 15, 2018. Interest was payable semi-annually in arrears, with payment due in April and October. The 2013 Notes were repaid in October 2018. In June 2018, the Company issued $600.0 million of fixed-rate unsecured senior notes (the "2018 Notes") due June 15, 2028. The proceeds from the 2018 Notes of $598.6 million, which is net of an issuance discount of $1.4 million, were used to repay amounts outstanding under the Company's Five-Year Credit Agreement and the remainder was used to partially repay the maturing 2013 Notes and for general corporate purposes. Interest is payable semi-annually in arrears, with the first payment due in December 2018.

The Company may redeem the 2013 Notes and the 2018 Notes (collectively the "Notes"), in whole or in part, at any time and from time to time at specified redemption prices. In addition, upon the occurrence of certain change of control triggering events, the Company may be required to repurchase all or a portion of the Notes at a price equal to 101% of their principal amount, plus accrued and unpaid interest. The Notes also include covenants that limit the Company's ability to incur secured indebtedness, enter into sale and leaseback transactions, and consolidate, merge, or transfer all or substantially all of its assets.

In April 2018, the Company entered into a new Five-Year Credit Agreement ("the Credit Agreement") which matures on April 28, 2023, and the previous Five-Year Credit Agreement was terminated. The Credit Agreement provides up to an aggregate of $750.0 million in borrowings in multiple currencies. Subject to certain terms and conditions, the Company may increase the amount available under the Credit Agreement by up to an additional $250.0 million in the aggregate. Borrowings generally bear interest at the London interbank offered rate ("LIBOR") plus a spread ranging from 0.9% to 1.3%, depending on the leverage ratio, as defined in the Credit Agreement. The Company also pays a facility fee ranging from 0.1% to 0.2%, depending on the leverage ratio, on the entire credit commitment available, whether drawn or not. The facility fee is expensed as incurred. Issuance costs of $2.4 million are being amortized to interest expense over the term of the Credit Agreement. As of September 30, 2018, there were no borrowings outstanding under the Credit Agreement. The Credit Agreement is unsecured and contains various financial and other covenants, including a maximum leverage ratio, as defined in the Credit Agreement. The Company was in compliance with all covenants as of September 30, 2018.
