Policies with a GMIB also have a GMDB, however these benefits are not additive. When a policy terminates due to death, any NAR related to GMIB is released. Similarly, when a policy goes into benefit status on a GMIB, its GMDB NAR is released.

Universal life

Liabilities for universal life contracts in excess of the account balance, some of which contain secondary guarantees, are generally determined by estimating the expected value of benefits and expenses when claims are triggered and recognizing those benefits and expenses over the accumulation period based on total expected assessments. The assumptions used in estimating these liabilities are generally consistent with those used for amortizing DAC.

Non-Insurance Guaranteed Product Features
Certain separate account variable products may contain a GMWB, guaranteed minimum accumulation benefit (“GMAB”) and/or combination (“COMBO”) rider as defined in Note 7 to our consolidated financial statements in the 2013 Form 10-K. These features are accounted for as embedded derivatives as described below.
