[1] | AV includes the contract holder’s investment in the separate account and the general account.
[2] | [9]NAR is defined as the guaranteed benefit in excess of the current AV. RNAR represents NAR reduced for reinsurance. NAR and RNAR are highly sensitive to equity markets movements and increase when equity markets decline.
[3] | ROP GMDB is the greater of current AV or net premiums paid.
[4] | MAV GMDB is the greatest of current AV, net premiums paid and the highest AV on any anniversary before age 80 years (adjusted for withdrawals).
[5] | Rollup GMDB is the greatest of the MAV, current AV, net premium paid and premiums (adjusted for withdrawals) accumulated at generally 5% simple interest up to the earlier of age 80 years or 100% of adjusted premiums.
[6] | EPB GMDB is the greatest of the MAV, current AV, or contract value plus a percentage of the contract’s growth. The contract’s growth is AV less premiums net of withdrawals, subject to a cap of 200% of premiums net of withdrawals.
[7] | APB GMDB is the greater of current AV or MAV, not to exceed current AV plus 25% times the greater of net premiums and MAV (each adjusted for premiums in the past 12 months).
[8] | LIB GMDB is the greatest of current AV; net premiums paid; or, for certain contracts, a benefit amount generally based on market performance that ratchets over time.
[9] | Reset GMDB is the greatest of current AV, net premiums paid and the most recent five to seven year anniversary AV before age 80 years (adjusted for withdrawals).
[10] | [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.
[11] | [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.
[12] | [6]Includes both market and non-market impacts in deriving realized and unrealized gains (losses).
[13] | [7]Amounts presented are for Level 3 only and therefore may not agree to other disclosures included herein.
