Long-term Debt

On November 10, 2020, Acuity Brands Lighting, Inc. (“ABL”), our wholly-owned operating subsidiary, issued $500.0 million aggregate principal amount of 2.150% senior unsecured notes due December 2030 (the "Unsecured Notes"). The Unsecured Notes bear interest at a rate of 2.150% per annum and were issued at a price equal to 99.737% of their face value. Interest on the Unsecured Notes will be paid semi-annually in arrears on June 15 and December 15 of each year, beginning on June 15, 2021. The Unsecured Notes will mature on December 15, 2030. The Unsecured Notes are fully and unconditionally guaranteed on a senior unsecured basis by Acuity Brands and ABL IP Holding LLC, a wholly-owned subsidiary of Acuity Brands. Additionally, we recorded $4.8 million of deferred issuance costs related to the Unsecured Notes as a direct deduction from the face amount of the Unsecured Notes. These issuance costs are amortized over the 10-year term of the Unsecured Notes. As of November 30, 2020, the balance of the bond net of unamortized discount and deferred issuance costs was $493.9 million.

As of November 30, 2020, we also had $4.0 million of tax-exempt industrial revenue bonds that are scheduled to mature in June 2021. The carrying value of these bonds is reflected within Current maturities of debt on the Consolidated Balance Sheets as of November 30, 2020. Additionally, we had $2.0 million outstanding under fixed-rate bank loans at November 30, 2020 that mature in February 2028, subject to monthly or quarterly repayment schedules. Further discussion of our long-term debt is included within the Debt and Lines of Credit footnote of the Notes to Consolidated Financial Statements within our Form 10-K.

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 provided us with a $400.0 million unsecured delayed draw term loan facility (the “Term Loan Facility”). We had no borrowings outstanding under the Revolving Credit Facility as of November 30, 2020 or August 31, 2020. We had $395.0 million of borrowings under the Term Loan Facility as of August 31, 2020, which we fully repaid during the first quarter of fiscal 2021 using the proceeds from the Unsecured Notes. The Credit Agreement allows for no future borrowings under the Term Loan Facility.

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 London Inter-Bank Offered Rate (“LIBOR”) or screen rate for the applicable currency plus an applicable margin. The Eurocurrency Rate 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%.

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 November 30, 2020. At November 30, 2020, we had additional borrowing capacity under the Credit Agreement of $395.9 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 $4.1 million issued under the Revolving Credit Facility. As of November 30, 2020, we had outstanding letters of credit totaling $8.3 million, primarily for securing collateral requirements under our casualty insurance programs and for providing credit support for our industrial revenue bond, which includes the $4.1 million issued under the Revolving Credit Facility.

Borrowings and repayments on our Revolving Credit Facility with terms of three months or less are reported on a net basis on our Consolidated Statements of Cash Flows.

Interest Expense, net

Interest expense, net, is comprised primarily of interest expense on long-term debt, obligations in connection with non-qualified retirement benefits, and Revolving Credit Facility borrowings, partially offset by interest income earned on cash and cash equivalents.
