Debt Disclosure [Abstract]
Debt	13. DEBT Junior Subordinated Debentures The U.K. Financial Conduct Authority ("FCA") announced that publication of U.S. dollar London Inter Bank Offered Rate (“LIBOR”) on a representative basis will cease immediately after June 30, 2023. LIBOR is used as a benchmark or reference rate for certain investments and derivatives the Company owns, and floating rate debt the Company has issued. Uncertainties and risks relating to the transition from LIBOR have been reduced by the federal Adjustable Interest Rate (LIBOR) Act, which addresses replacement of LIBOR in certain contracts governed by U.S. law (including the law of any U.S. state), including 3-Month LIBOR, which was the original reference rate on the Company's $500 junior subordinated debentures due 2067. Prior to July 1, 2023, the Company's $500 junior subordinated debentures due 2067 paid interest at a rate of LIBOR plus 2.125%. Effective July 1, 2023, the interest rate on the $500 junior subordinated debentures due 2067 is determined based on a reference rate of 3-month CME term Secured Overnight Financing Rate (“SOFR”) plus a spread adjustment of 0.26161% plus 2.125%. The Company's interest rate swap agreements that converted the LIBOR variable interest payments on the $500 junior subordinated debentures to fixed interest payments were terminated and new interest rate swap agreements were entered into that reference SOFR so that interest rate swaps continue to effectively convert the variable interest payments to fixed interest payments of approximately 4.39%.
