Senior Unsecured Notes On June 7, 2018, we issued $300.0 million of 4.625 percent Senior Unsecured Notes with a maturity date of June 15, 2028. Interest will be paid semi-annually on June 15 and December 15 of each year. We used the net proceeds from the offering of the notes, plus cash on hand, for the early extinguishment of our $400.0 million of 2.650 percent Senior Unsecured Notes ($400.0 million Notes) in July of fiscal 2019. The $400 million Notes, with an original maturity date of November 1, 2019, were reclassified to current maturities of long-term debt as of June 30, 2018, since our notification of early redemption to bondholders in June 2018 created an irrevocable commitment to redeem the debt. Interest on the $400 million Notes was paid semi-annually on May 1 and November 1 of each year. On February 14, 2012, we issued $300 million of 3.875 percent Senior Unsecured Notes with a maturity date of February 15, 2022. Interest on these Notes is paid semi-annually on February 15 and August 15 of each year.

Credit Agreement The five-year, multi-currency, revolving credit facility, as amended and restated in June 2018 (Credit Agreement) provides for revolving credit loans of up to $700.0 million for working capital, capital expenditures and general corporate purposes. The Credit Agreement matures in June 2023 and allows for borrowings in U.S. dollars, euros, Canadian dollars, pounds sterling and Japanese yen. Interest payable under the Credit Agreement is based upon the type of borrowing under the facility and may be (1) LIBOR plus an applicable margin, (2) the greater of the prime rate or the Federal Funds effective rate plus an applicable margin, or (3) fixed as negotiated by us.

The Credit Agreement requires us to comply with various restrictive and affirmative covenants, including two financial covenants: a maximum leverage ratio and a minimum consolidated interest coverage ratio (as those terms are defined in the Credit agreement). We were in compliance with all covenants as of June 30, 2019. We had no borrowings outstanding under the Credit Agreement as of June 30, 2019 and 2018. Borrowings under the Credit Agreement are guaranteed by our significant domestic subsidiaries.

Future principal maturities of long-term debt are $300 million in 2022 and $300 million in 2028.
