[1] | [2]All amounts in these rows are reported in net realized capital gains (losses). The realized/unrealized gains (losses) included in net income for separate account assets are offset by an equal amount for separate account liabilities, which results in a net zero impact on net income for the Company. All amounts are before income taxes and amortization of DAC.
[2] | [7]Amounts presented are for Level 3 only and therefore may not agree to other disclosures included herein.
[3] | [1]The Company classifies gains and losses on GMWB reinsurance derivatives and GMWB embedded derivatives as unrealized gains (losses) for purposes of disclosure in this table because it is impracticable to track on a contract-by-contract basis the realized gains (losses) for these derivatives and embedded derivatives.
[4] | [6]Includes both market and non-market impacts in deriving realized and unrealized gains (losses).
[5] | [3]All amounts are before income taxes and amortization of DAC.
[6] | [4]Transfers in and/or (out) of Level 3 are primarily attributable to the availability of market observable information and the re-evaluation of the observability of pricing inputs.
[7] | Conversely, the impact of a decrease in input would have the opposite impact to the fair value as that presented in the table.
[8] | [2]Range represents assumed cumulative percentages of policyholders taking withdrawals.
[9] | Range represents assumed cumulative annual amount withdrawn by policyholders.
[10] | Range represents assumed annual percentages of full surrender of the underlying variable annuity contracts across all policy durations for in force business.
[11] | Range represents assumed cumulative percentages of policyholders that would elect to reset their guaranteed benefit base.
[12] | Range represents implied market volatilities for equity indices based on multiple pricing sources.
[13] | Gross unrealized gains (losses) exclude the fair value of bifurcated, embedded derivative features of certain securities. Subsequent changes in value are recorded in net realized capital gains (losses).
