Debt Disclosure [Abstract] |
LONG-TERM DEBT | LONG-TERM DEBT Mortgage Bonds In March 2019, KCP&L issued collateral mortgage bonds secured by the General Mortgage Indenture and Deed of Trust dated as of December 1, 1986, as supplemented (KCP&L Mortgage Indenture) to serve as collateral for KCP&L's obligations under the following outstanding unsecured senior notes:
• | $300.0 million of 3.15% Series, maturing in 2023;
• | $350.0 million of 3.65% Series, maturing in 2025;
• | $250.0 million of 6.05% Series, maturing in 2035;
• | $400.0 million of 5.30% Series, maturing in 2041;
• | $300.0 million of 4.20% Series, maturing in 2047; and
• | $300.0 million of 4.20% Series, maturing in 2048.
The collateral mortgage bonds were issued to the trustee for the unsecured senior notes, are only payable if KCP&L defaults on the underlying unsecured senior notes and do not increase the amount of outstanding debt for KCP&L. As a result of the above transactions, KCP&L's outstanding senior notes have effectively become secured by the mortgage lien of the KCP&L Mortgage Indenture and will rank equally and ratably with all of KCP&L's mortgage bonds, regardless of series, from time to time issued and outstanding under the KCP&L Mortgage Indenture. Also in March 2019, KCP&L issued, at a discount, $400.0 million of 4.125% Mortgage Bonds, maturing in 2049. KCP&L also repaid its $400.0 million of 7.15% Mortgage Bonds at maturity in April 2019. Senior Notes In March 2019, GMO issued $100.0 million of 3.74% Senior Notes, maturing in 2022, under a note purchase agreement.
