Lines of Credit

On June 29, 2018, we entered into a credit agreement (“Credit Agreement”) with a syndicate of banks that provides us with a $400.0 million five-year unsecured revolving credit facility (“Revolving Credit Facility”) and a $400.0 million Term Loan Facility. We had no borrowings outstanding under the Revolving Credit Facility as of August 31, 2020 or 2019. We had $395.0 million in borrowings outstanding under the Term Loan Facility as of August 31, 2020 and no borrowings outstanding under the Term Loan Facility as of August 31, 2019. Based on the repayment schedule, $375.0 million of the borrowings under the Term Loan Facility are reflected within Long-term debt on the Consolidated Balance Sheets as of August 31, 2020.

Generally, amounts outstanding under the Revolving Credit Facility allow for borrowings to bear interest at either the Eurocurrency Rate or the base rate at our option, plus an applicable margin. Eurocurrency Rate advances can be denominated in a variety of currencies, including U.S. Dollars, and amounts outstanding bear interest at a periodic fixed rate equal to the LIBOR for the applicable currency plus an applicable margin. The Eurocurrency applicable margin is based on our leverage ratio, as defined in the Credit Agreement, with such margin ranging from 1.000% to 1.375% Base rate advances bear interest at an alternate base rate plus an applicable margin. The base rate applicable margin is based on our leverage ratio, as defined in the Credit Agreement, with such margin ranging from 0.000% to 0.375%. The Term Loan Facility allowed for borrowings to be drawn over a one-year period ending December 31, 2019, utilizing up to four separate installments, which are U.S. dollar denominated. Borrowings under the Term Loan

Facility amortize in equal quarterly installments of 2.5% per year in year one, 2.5% per year in year two, 5.0% per year in year three, 5.0% per year in year four, and 7.5% per year in year five. Any remaining borrowings under the Term Loan Facility are due and payable in full on June 29, 2023. The Term Loan Facility allows for borrowings to bear interest at either a Eurocurrency Rate or the base rate, at our option, in each case plus an applicable margin. Eurocurrency Rate advances can be denominated in a variety of currencies, including U.S. Dollars, and amounts outstanding bear interest at a periodic fixed rate equal to the LIBOR for the applicable currency plus an applicable margin. The Eurocurrency applicable margin is based on our leverage ratio, as defined in the Credit Agreement, with such margin ranging from 0.875% to 1.250%. Base Rate advances bear interest at an alternate base rate plus an applicable margin. The base rate applicable margin is based on our leverage ratio, as defined in the Credit Agreement, with such margin ranging from 0.0% to 0.25%.

We are required to pay certain fees in connection with the Credit Agreement, including administrative service fees and annual facility fees. The annual facility fee is payable quarterly, in arrears, and is determined by our leverage ratio as defined in the Credit Agreement. The facility fee ranges from 0.125% to 0.250% of the aggregate $800.0 million commitment of the lenders under the Credit Agreement. The Credit Agreement contains financial covenants, including a minimum interest expense coverage ratio (“Minimum Interest Expense Coverage Ratio”) and a leverage ratio (“Maximum Leverage Ratio”) of total indebtedness to earnings before interest, tax, depreciation, and amortization (“EBITDA”), as such terms are defined in the Credit Agreement. These ratios are computed at the end of each fiscal quarter for the most recent 12-month period. The Credit Agreement generally allows for a Minimum Interest Expense Coverage Ratio of 2.50 and a Maximum Leverage Ratio of 3.50, subject to certain conditions, as such terms are defined in the Credit Agreement.

We were in compliance with all financial covenants under the Credit Agreement as of August 31, 2020. At August 31, 2020, we had additional borrowing capacity under the Credit Agreement of $396.2 million under the most restrictive covenant in effect at the time, which represents the full amount of the Revolving Credit Facility less the outstanding letters of credit of $3.8 million issued under the Revolving Credit Facility. As of August 31, 2020, we had outstanding letters of credit totaling $8.1 million, primarily for securing collateral requirements under our casualty insurance programs and for providing credit support for our industrial revenue bond, which includes $3.8 million we issued under the Revolving Credit Facility.

Long-term Debt

On December 16, 2019, we repaid $350 million of senior unsecured notes in full plus accrued interest in full with borrowings under our Term Loan Facility.

We also had $4.0 million of tax-exempt industrial revenue bonds that are scheduled to mature in June 2021 outstanding at August 31, 2020. The carrying value of these bonds is reflected within Current maturities of debt on the Consolidated Balance Sheets as of August 31, 2020. The interest rate on the $4.0 million bonds was approximately 1.0% at August 31, 2020 and 2019. Additionally, we had $2.1 million outstanding under fixed-rate bank loans. These loans have interest rates between 0.8% and 2.0% and mature between December 2022 and February 2028, subject to monthly or quarterly repayment schedules.

None of our existing debt instruments include provisions that would require an acceleration of repayments based solely on changes in our credit ratings.
