Accounting Changes And Error Corrections [Abstract]
New accounting pronouncements	In August 2018, the Financial Accounting Standards Board issued Accounting Standards Update 2018-12 “Targeted Improvements to the Accounting for Long-Duration Contracts” (“ASU 2018-12”). ASU 2018-12 requires reassessment of cash flow assumptions at least annually and revision of discount rate assumptions each reporting period in valuing policyholder liabilities and related deferred acquisition costs of long-duration contracts. The effects from changes in cash flow assumptions are reflected in earnings and the effects from changes in discount rate assumptions are reflected in other comprehensive income. Currently, the cash flow and discount rate assumptions are set at the contract inception date and not subsequently changed, except under limited circumstances. ASU 2018-12 is to be applied retrospectively to the earliest period presented in the financial statements, will require new disclosures and is effective for fiscal years beginning after December 15, 2022, with early adoption permitted. We currently intend to adopt ASU 2018-12 as of January 1, 2023 using the modified retrospective method, which provides that revised cash flow and discount rate assumptions as of January 1, 2021 (the transition date) be applied to contracts then in-force, with liabilities then remeasured as provided under the standard. The cumulative effects from discount rate assumption changes as of the transition date will be recorded in accumulated other comprehensive income and the cumulative effect from cash flow assumption changes will be recorded in retained earnings. While we have not finalized our assessment of the impact of the adoption as of the transition date, we currently believe that the changes in discount rate assumptions will have a greater effect on our recorded liabilities than changes in cash flow assumptions. We also preliminarily estimate that the changes in discount rate assumptions as of the transition date will increase our life, health and annuity benefit liabilities from the amounts previously reported due to the historically low interest rate environment at that time. However, the ultimate impact of adopting ASU 2018-12 will be based on the discount rate and cash flow assumptions determined as of the January 1, 2023 adoption date. We, therefore, continue to evaluate the effect this standard will have on our Consolidated Financial Statements.
