The range for indexed annuity contracts represents the lapse rates during the surrender charge period.(4)The utilization of guaranteed withdrawals input represents the estimated percentage of contract holders that utilize the guaranteed withdrawal feature.(5)The utilization factors are applied to the present value of claims or premiums, as appropriate, in the GLB reserve calculation to estimate the impact of inefficient withdrawal behavior, including taking less than or more than the maximum guaranteed withdrawal.(6)The NPR input represents the estimated additional credit spread that market participants would apply to the market observable discount rate when pricing a contract. The NPR input was weighted by the absolute value of the sensitivity of the reserve to the NPR assumption. (7)The mortality rate input represents the estimated probability of when an individual belonging to a particular group, categorized according to age or some other factor such as gender, will die.(8)The volatility input represents overall volatilities assumed for the underlying variable annuity funds, which include a mixture of equity and fixed-income assets. Fair value of the variable annuity GLB embedded derivatives would increase if higher volatilities were used for valuation. Volatility assumptions vary by fund due to the benchmarking of different indices. The volatility input was weighted by the relative account value assigned to each index.(9)The mortality rate is based on a combination of company and industry experience, adjusted for improvement factors.(10)A weighted average input range is not a meaningful measurement for lapse rate, utilization factors or mortality rate.
