Fair Value Disclosures [Abstract] |
Recurring Fair Value Measurements | The assets and liabilities measured at estimated fair value on a recurring basis and their corresponding placement in the fair value hierarchy are presented in the tables below. Investments that do not have a readily determinable fair value and are measured at net asset value (or equivalent) as a practical expedient to estimated fair value are excluded from the fair value hierarchy.

Fair Value Measurement Inputs and Valuation Techniques | Certain quantitative information about the significant unobservable inputs used in the fair value measurement, and the sensitivity of the estimated fair value to changes in those inputs, for the more significant asset and liability classes measured at fair value on a recurring basis using significant unobservable inputs (Level 3) were as follows at:

_______________ (1)Mortality rates vary by age and by demographic characteristics such as gender. The range shown reflects the mortality rate for policyholders between 35 and 90 years old. Mortality rate assumptions are set based on company experience and include an assumption for mortality improvement. (2)The lapse rate range reflects base lapse rates for major product categories for duration 1-20. Base lapse rates are adjusted at the contract level based on a comparison of the actuarially calculated guaranteed values and the current policyholder account value, as well as other factors, such as the applicability of any surrender charges. For variable annuity guarantees, a dynamic lapse function reduces the base lapse rate when the guaranteed amount is greater than the account value as in-the-money contracts are less likely to lapse. Lapse rates are also generally assumed to be lower in periods when a surrender charge applies. (3)The utilization rate assumption for variable annuity guarantees estimates the percentage of contract holders with a GMIB or lifetime withdrawal benefit who will elect to utilize the benefit upon becoming eligible in a given year. The range shown represents the floor and cap of the GMIB dynamic election rates across varying levels of in-the-money. For lifetime withdrawal guarantee riders, the assumption is that everyone will begin withdrawals once account value reaches zero which is equivalent to a 100% utilization rate. Utilization rates may vary by the type of guarantee, the amount by which the guaranteed amount is greater than the account value, the contract’s withdrawal history and by the age of the policyholder. (4)The withdrawal rate represents the percentage of account balance that any given policyholder will elect to withdraw from the contract each year. The withdrawal rate assumption varies by age and duration of the contract, and also by other factors such as benefit type. For any given contract, withdrawal rates vary throughout the period over which cash flows are projected for purposes of valuing the embedded derivative. For variable annuity GMWBs, any increase (decrease) in withdrawal rates results in an increase (decrease) in the estimated fair value of the guarantees. For variable annuity GMABs and GMIBs, any increase (decrease) in withdrawal rates results in a decrease (increase) in the estimated fair value. (5)Long-term equity volatilities represent equity volatility beyond the period for which observable equity volatilities are available. For any given contract, long-term equity volatility rates vary throughout the period over which cash flows are projected for purposes of valuing MRBs. (6)Nonperformance risk spread varies by duration. For any given contract, multiple nonperformance risk spreads will apply, depending on the duration of the cash flow being discounted for purposes of valuing the MRB or embedded derivative.
