[1] [6]Includes fair value of reinsurance recoverables of approximately $539 and $435 as of March 31, 2014 and 2013, respectively, related to a transaction entered into with an affiliated captive reinsurer. See Note 11 - Transactions with Affiliates of Notes to Condensed Consolidated Financial Statements for more information.

[2] [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.

[3] [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.

[4] [3]All amounts are before income taxes and amortization of DAC.

[5] [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.

[6] [7]Includes both market and non-market impacts in deriving realized and unrealized gains (losses).
