[1] 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] Includes both market and non-market impacts in deriving realized and unrealized gains (losses).

[3] 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 reinsurance derivatives and embedded derivatives.

[4] All amounts are before income taxes and amortization of DAC.

[5] Transfers in and/or (out) of Level 3 are primarily attributable to the availability of market observable information, the re-evaluation of the observability of pricing inputs and liquidity restrictions.

[6] [7]Amounts presented are for Level 3 only and therefore may not agree to other disclosures included herein.

[7] Derivative instruments are reported in this table on a net basis for asset (liability) positions and reported in the Consolidated Balance Sheets in other investments and other liabilities.
