Short-Term Borrowing [Abstract]

Short-term Debt [Text Block]

16.    Short-Term Borrowings

At March 31, 2021 and December 31, 2020, we had $156.1 million and $175.6 million, respectively, of short-term borrowings outstanding at a weighted average interest rate of 1.11 percent and 1.28 percent. Included in the March 31, 2021 balance, is $100.0 million in short-term debt for which we have entered into interest rate swap agreements.

In September 2020, we entered into a $375.0 million syndicated Revolver with six participating lenders. As a result of entering into the Revolver, in September 2020, we terminated and paid all outstanding balances under the previously existing bilateral lines of credit and the previous revolving credit facility.

The availability of funds under the Revolver is subject to conditions specified in the credit agreement, all of which we currently satisfy. These conditions include our compliance with financial covenants and the continued accuracy of representations and warranties contained in these agreements. We are required by the financial covenants in the Revolver to maintain, at the end of each fiscal year, a funded indebtedness ratio of no greater than 65 percent. As of March 31, 2021, we are in compliance with this covenant.

The Revolver expires on September 29, 2021 and is available to provide funds for our short-term cash needs to meet seasonal working capital requirements and to temporarily fund portions of our capital expenditures. Borrowings under the Revolver are subject to a pricing grid, including the commitment fee and the interest rate charged. Our pricing is adjusted each quarter based upon total indebtedness to total capitalization ratio. As of March 31, 2021, the pricing under the Revolver included an unused commitment fee of 0.15 percent and an interest rate of 1.0 percent over LIBOR. Our available credit under the Revolver at March 31, 2021 was $214.1 million. As of March 31, 2021, we had issued $4.8 million in letters of credit to various counterparties under the syndicated Revolver. Although the letters of credit are not included in the outstanding short-term borrowings and we do not anticipate they will be drawn upon by the counterparties, the letters of credit reduce the available borrowings under our syndicated Revolver.

In the fourth quarter of 2020, we entered into interest rate swaps with a notional amount of $60.0 million through December 2021 with pricing of 0.20 and 0.205 percent for the period associated with our outstanding borrowing under the Revolver. In February 2021, we entered into an additional interest rate swap with a notional amount of $40.0 million through December 2021 with pricing of 0.17 percent. Our short-term borrowing is based on the 30-day LIBOR rate. The interest rate swaps are cash settled monthly as the counter-party pays us the 30-day LIBOR rate less the fixed rate.

We are authorized by our Board of Directors to borrow up to $375.0 million of short-term debt, as required.
