Short-Term Debt [Abstract] |
Short-Term Borrowings | We generate short-term borrowings from our revolving credit facility, commercial paper program, accounts receivable transfer programs, and term credit agreement. Each of these borrowing sources is described further below. Revolving Credit Facility. We maintain a revolving credit facility to fund ongoing working capital requirements, including the provision of liquidity support for our commercial paper program, provide for issuance of letters of credit, and also for general corporate purposes. Our revolving credit facility has a program limit of $1.85 billion and is comprised of a syndicate of banks. On February 18, 2022, we extended the termination date of our revolving credit facility to February 18, 2027. At December 31, 2022 and 2021, we had no outstanding borrowings under this facility. Commercial Paper Program. Our commercial paper program has a program limit of up to $1.5 billion. We had $415.0 million and $560.0 million of commercial paper outstanding with weighted-average interest rates of 4.60% and 0.24% as of December 31, 2022 and 2021, respectively. Accounts Receivable Transfer Programs. Columbia of Ohio, NIPSCO, and Columbia of Pennsylvania each maintain a receivables agreement whereby they transfer their customer accounts receivables to third party financial institutions through wholly-owned and consolidated special purpose entities. The three agreements expire between May 2023 and October 2023 and may be further extended if mutually agreed to by the parties thereto. All receivables transferred to third parties are valued at face value, which approximates fair value due to their short-term nature. The amount of the undivided percentage ownership interest in the accounts receivables transferred is determined in part by required loss reserves under the agreements. Transfers of accounts receivable are accounted for as secured borrowings resulting in the recognition of short-term borrowings on the Consolidated Balance Sheets. As of December 31, 2022, the maximum amount of debt that could be recognized related to our accounts receivable programs is $500.0 million. We had $347.2 million and no short-term borrowings related to the securitization transactions as of December 31, 2022 and 2021, respectively. For the years ended December 31, 2022 and 2021, $347.2 million and zero, respectively, were recorded as cash flows from financing activities related to the change in short-term borrowings due to securitization transactions. For the accounts receivable transfer programs, we pay used facility fees for amounts borrowed, unused commitment fees for amounts not borrowed, and upfront renewal fees. Fees associated with the securitization transactions were $2.5 million, $1.4 million, and $2.6 million for the years ended December 31, 2022, 2021 and 2020, respectively. Columbia of Ohio, NIPSCO and Columbia of Pennsylvania remain responsible for collecting on the receivables securitized, and the receivables cannot be transferred to another party. Term Credit Agreement. On December 20, 2022, we entered into a $1.0 billion term credit agreement with a syndicate of banks. The agreement matures on December 19, 2023 and interest charged on the borrowings depends on the variable rate structure elected at the time of each borrowing. The available variable rate structures from which we can choose are defined in the agreement. Under the agreement, we borrowed $1.0 billion on December 20, 2022 with an interest rate of SOFR plus 105 basis points. We had $1.0 billion outstanding with an interest rate of 5.37% as of December 31, 2022. Items listed above, excluding the term credit agreement, are presented net in the Statements of Consolidated Cash Flows as their maturities are less than 90 days.
