unobservable input range.No definition available.false0Range of Values-Unobservable Inputs1Ranges represent assumed cumulative percentages of policyholders taking withdrawals and the annual amounts withdrawn.2Conversely, the impact of a decrease in input would have the opposite impact to the fair value as that presented in the table.3For reinsurance associated with Japan GMIB, range represents assumed cumulative percentages of policyholders annuitizing variable annuity contracts.4Range represents assumed annual percentages of full surrender of the underlying variable annuity contracts across all policy durations for in force business.5Range represents assumed cumulative percentages of policyholders that would elect to reset their guaranteed benefit base.6Range represents implied market volatilities for equity indices based on multiple pricing sources.falseFair Value Measurements (Details 2) (Level 3
