Long-Term Debt, Unclassified [Abstract] |
Long-Term Debt | 8. Long-Term Debt At September 30, 2025, the Registrants were in compliance with all of their debt agreements. OG&E Industrial Authority Bonds OG&E has tax-exempt pollution control bonds with optional redemption provisions that allow the holders to request repayment of the bonds on any business day. The following table presents information about these bonds, which can be tendered at the option of the holder during the next 12 months.
Series |  | Date Due |  | Amount |
|  |  |  |  |  |  |  | (In millions) |
1.65% |  | - |  | 4.60% |  | Muskogee Industrial Authority, June 1, 2027 |  | $ | 56.0 |
1.80% |  | - |  | 4.60% |  | Garfield Industrial Authority, October 1, 2039 |  |  | 47.0 |
Total (redeemable during next 12 months) |  | $ | 103.0 |
OG&E repaid $32.4 million of Muskogee Industrial Authority bonds that matured on January 1, 2025. All of these bonds are subject to an optional tender at the request of the holders, at 100 percent of the principal amount, together with accrued and unpaid interest to the date of purchase. The bond holders, on any business day, can request repayment of the bond by delivering an irrevocable notice to the tender agent stating the principal amount of the bond, payment instructions for the purchase price and the business day the bond is to be purchased. The repayment option may only be exercised by the holder of a bond for the principal amount. When a tender notice has been received by the trustee, a third-party remarketing agent for the bonds will attempt to remarket any bonds tendered for purchase. This process occurs once per week. Since the original issuance of these series of bonds in 1995 and 1997, the remarketing agent has successfully remarketed all tendered bonds. If the remarketing agent is unable to remarket any such bonds, OG&E is obligated to repurchase such unremarketed bonds. As OG&E has both the intent and ability to refinance the bonds on a long-term basis and such ability is supported by an ability to consummate the refinancing, the remarketing of bonds does not result in short-term debt classification in the condensed balance sheets. OG&E believes that it has sufficient liquidity to meet these obligations. Issuance of Long-Term Debt On April 1, 2025, OG&E issued $350.0 million of 5.80 percent senior notes due April 1, 2055. The proceeds from this issuance were added to OG&E's general funds and used for the repayment of short-term debt and borrowings under its revolving credit facility, and to fund OG&E's capital investment program and working capital needs.
