[1] 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).

[2] 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.

[3] 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 withdrawals.

[4] 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).

[5] 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.

[6] 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).

[7] ROP GMDB is the greater of current AV and net premiums paid.

[8] Includes account value for contracts that had a GMDB at issue but no longer have a GMDB due to certain elections made by policyholders or their beneficiaries.

[9] AV includes the contract holder’s investment in the separate account and the general account.

[10] NAR is defined as the guaranteed minimum death benefit in excess of the current AV. RNAR represents NAR reduced for reinsurance. NAR and RNAR are highly sensitive to equity market movements and increase when equity markets decline.

[11] Some variable annuity contracts with GMDB also have a life-contingent GMWB that may provide for benefits in excess of the return of the GRB. Such contracts included in this amount have $5.1 billion of total account value and weighted average attained age of 74 years. There is no NAR or retained NAR related to these contracts.
