[1] [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.

[2] [7]Includes both market and non-market impacts in deriving realized and unrealized gains (losses).

[3] [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.
