The Company maintains committed and unsecured credit facilities and irrevocable letters of credit as part of its normal and recurring business operations. The purpose of these credit facilities is to meet short-term funding requirements, finance working capital needs, and for general corporate purposes. The Company typically borrows on an overnight or short-term basis on its credit facilities.

Details of the Company’s credit facilities are as follows:

⁽¹⁾JPM acts as the administrative agent for this syndicated credit facility.

⁽²⁾This agreement replaced the Company’s predecessor four year unsecured $150.0 million credit facility dated March 17, 2016, which was terminated on February 6, 2020.

⁽³⁾The total amount available under these credit facilities as of May 31, 2021 was approximately $1.7 billion. Amounts under the PNC credit facility remain outstanding as of the date of this report.

Upon the expiration date of any credit facility, any borrowings outstanding under that facility will mature and be payable.

Interest rates on each of the Company’s credit facilities can be based upon (1) an alternate base rate that is established by the lending institution at the highest of several publicly available interest rates, plus an applicable interest rate margin, or (2) at our election, the adjusted London Interbank Offered Rate (“LIBOR”) or an alternate interest rate as determined by the administrative agent, plus an applicable interest rate margin. The Company is also required to pay a commitment fee, ranging from 0.05% to 0.15%, related to the unutilized portion of each credit facility. The commitment fee is determined on a sliding-scale basis based upon the Company’s consolidated leverage ratio.

Obligations under the credit facilities are guaranteed by the Company and certain of its subsidiaries. The credit facilities contain financial and operational covenants with which the Company must maintain compliance. The Company’s ability to borrow under the credit facilities may be restricted in the event of certain covenant breaches or events of default. In addition, the terms of the credit facilities could restrict the Company’s ability to engage in certain business transactions. The Company was in compliance with all these covenants as of May 31, 2021.

Certain lenders under these credit facilities, and their respective affiliates, have performed, and may in the future perform for the Company, various commercial banking, investment banking, underwriting, and other financial advisory services, for which they have received, and will continue to receive in the future, customary fees and expenses.

Letters of credit: The Company had irrevocable standby letters of credit outstanding totaling $180.4 million and $147.9 million as of May 31, 2021 and May 31, 2020, respectively, required to secure commitments for certain insurance policies. The letters of credit expire at various dates between June 26, 2021 and July 15, 2022. No amounts were outstanding on these letters of credit during fiscal 2021 or fiscal 2020, or as of May 31, 2021 and May 31, 2020. Subsequent to May 31, 2021, a $41.2 million letter of credit was cancelled, and letters of credit expiring on June 26, 2021 were renewed through June 26, 2022.
