Credit Facilities

On June 30, 2021, we amended our existing credit agreement, dated May 14, 2019, with BMO Harris Bank N.A. The amendment added an unsecured fixed-rate term loan commitment not to exceed a principal amount of $100.0 million and increased our borrowing capacity with BMO Harris Bank N.A. from $200.0 million to $300.0 million. The outstanding principal balance of the term loan shall bear interest at a fixed rate of 1.28%.

As of June 30, 2021, we had unsecured committed credit facilities with two banks, as well as the new term loan commitment described above with one of these banks. We had with Wells Fargo Bank, N.A. a $300.0 million credit facility which will expire on May 14, 2024. We also had a $200.0 million credit facility with BMO Harris Bank N.A., which will expire on May 14, 2024, and a $100.0 million term loan with quarterly principal payments of $1.25 million beginning September 30, 2021 and a final payment of principal and interest due and payable on May 14, 2024. Borrowings under these credit facilities bear variable interest based on the London Interbank Offered Rate (“LIBOR”), and the term loan has a fixed interest rate.

As of June 30, 2021 and December 31, 2020, our outstanding debt totaled $300.0 million and $200.0 million, respectively. Under the credit facilities as of June 30, 2021, we had $50.0 million outstanding at a weighted average variable interest rate of 0.77% and $100.0 million outstanding at a fixed interest rate of 1.28%. We had (i) an additional $75.0 million outstanding under the Wells Fargo Bank, N.A. credit facility at a variable rate of 0.76% as of June 30, 2021, which is effectively fixed at 2.32% with an interest rate swap agreement through May 14, 2024 and (ii) an additional $75.0 million outstanding under the BMO Harris Bank N.A. credit facility at a variable rate of 0.79% as of June 30, 2021, which is effectively fixed at 2.36% with an interest rate swap agreement through May 14, 2024. The $600.0 million of borrowing capacity under our credit arrangements at June 30, 2021, is further reduced by $50.9 million in stand-by letters of credit under which we are obligated. Each of the debt agreements includes, among other things, financial covenants requiring us (i) to exceed a minimum ratio of

earnings before interest, income taxes, depreciation and amortization to interest expense and/or (ii) not to exceed a maximum ratio of total funded debt to earnings before interest, income taxes, depreciation and amortization (as such terms are defined in each credit facility). At June 30, 2021, we were in compliance with these covenants.

At June 30, 2021, the aggregate future maturities of long-term debt by year are as follows (in thousands):

2021	$	2,500
2022	5,000
2023	5,000
2024	287,500
2025	—
Total	$	300,000

The carrying amounts of our long-term debt approximate fair value due to the duration of the notes and the variable interest rates.
