Quantitative Information, Level 3 Fair Value Measurements
The following table provides quantitative information about the significant unobservable inputs used for recurring fair value measurements categorized within Level 3, excluding investments where third party valuation inputs were not reasonably available. The market risk benefits are also excluded from the table. See Note 8 - Policyholder Liabilities for information on the unobservable inputs used in the fair value measurements of market risk benefits. See discussion of the valuation technique and significant unobservable inputs used for the embedded derivative component of our fixed index annuities in the Fixed index annuities-embedded derivatives paragraph below.
