The liability for death and income benefit guarantees is established equal to a benefit ratio, multiplied by the cumulative contract charges earned, plus accrued interest less contract benefit payments. The benefit ratio is calculated as the estimated present value of all expected contract benefits divided by the present value of all expected contract charges. The benefit ratio may be in excess of 100%. For guarantees in the event of death, benefits represent the current guaranteed minimum death payments in excess of the current account balance. For guarantees at annuitization, benefits represent the present value of the minimum guaranteed annuity benefits in excess of the current account balance.

Projected benefits and assessments used in determining the liability for contract guarantees are developed using a projection model and stochastic scenarios. Underlying assumptions for the liability related to income benefits include assumed future annuitization elections based upon factors such as eligibility conditions and the annuitant's attained age.

The liability for guarantees is re-calculated and adjusted regularly. Changes to the liability balance are recorded as a charge or credit to policyowner benefits.

GMABs and GMWBs are considered to be derivatives under FASB ASC Topic 815 and are recorded at fair value through earnings. The Company records GMAB and GMWB assets or liabilities in its consolidated balance sheets as part of contractholder deposit funds and other policy liabilities. The net balance of GMABs and GMWBs constituted a liability in the amount of $1,286.8 million and $2.3 million at December 31, 2011 and 2010, respectively. The Company includes the following unobservable inputs in its calculation of the embedded derivative:

Actively-Managed Volatility Adjustments – This component incorporates the basis differential between the observable implied volatilities for each index and the actively-managed funds underlying the variable annuity product. The adjustment is based upon historical actively-managed fund volatilities and historical weighted-average index volatilities.

Credit Standing Adjustment – This component makes an adjustment that market participants would make to reflect the non-performance risk associated with the embedded derivatives. The adjustment is based upon the published credit spread for A-rated corporate bonds, which have ratings that are equivalent to the rating of the Company.

Behavior Risk Margin – This component adds a margin that market participants would require for the risk that the Company's best estimate policyholder behavior assumptions could differ from actual experience. This risk margin is determined by taking the difference between the fair value based on adverse policyholder behavior assumptions and the fair value based on best estimate policyholder behavior assumptions, using assumptions the Company believes market participants would use in developing risk margins.
