(1) As of June 30, 2026, there was $296 million outstanding under the committed line of credit; however, $226 million was classified as short-term borrowings and $70 million was classified as long-term on the Condensed Consolidated Balance Sheet due to the Company's intention to refinance such amount on a long-term basis. The amount classified as long-term debt will be refinanced through the issuance and sale of first mortgage bonds in August 2026, pursuant to a bond purchase agreement entered into in May 2026. See Note 10 for further discussion of the first mortgage bonds and the refinancing of short-term debt on a long-term basis. The entire outstanding amount of the committed line of credit as of December 31, 2025 was classified as short-term borrowings on the Condensed Consolidated Balance Sheet.
