[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 Guaranteed Living Benefit 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] [5]Derivative instruments are reported in this table on a net basis for asset/(liability) positions and reported in the Condensed Consolidated Balance Sheet in other investments and other liabilities.
