The Company has a multi-currency revolving credit facility with a group of lenders. On July 21, 2017, the Company entered into an amended and restated credit agreement that increases the borrowing availability to $500.0 million and extends the maturity date of the credit facility to July 21, 2022. The credit facility also has an accordion feature that allows the Company to request an increase to the commitment under the facility by up to $250.0 million. At July 31, 2018 and 2017, $324.5 million and $299.5 million, respectively, was available for further borrowing under this facility. The amount available for further borrowing reflects the issued standby letters of credit, as discussed in Note 16, as issued standby letters of credit reduce the amounts available for borrowing under this facility. The credit facility also includes a $50.0 million term loan due July 21, 2020. Borrowings under the Company's amended revolving credit facility are automatically rolled over until the credit facility maturity date unless the agreement is terminated early or the Company is found to be in default.

Certain debt agreements, including the $500.0 million revolving credit facility, contain financial covenants related to interest coverage and leverage ratios. As of July 31, 2018, the Company was in compliance with all such covenants.
