[1] Excludes equity securities, FVO, with a cost and fair value of $351 and $348, respectively, as of December 31, 2014. The Company did not hold any equity securities, FVO as of September 30, 2015.

[2] [1]Included in other investments on the Condensed Consolidated Balance Sheets.

[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] [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.

[5] [6]Includes both market and non-market impacts in deriving realized and unrealized gains (losses).

[6] [3]All amounts are before income taxes and amortization of DAC.

[7] [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.

[8] [7]Amounts presented are for Level 3 only and therefore may not agree to other disclosures included herein.

[9] [5]Derivative instruments are reported in this table on a net basis for asset (liability) positions and reported in the Condensed Consolidated Balance Sheets in other investments and other liabilities.

[10] Gross unrealized gains (losses) exclude the fair value of bifurcated embedded derivatives within certain securities. Subsequent changes in value are recorded in net realized capital gains (losses).
