Fair Value Measurement Inputs and Valuation Techniques
The tables below present quantitative information about the significant unobservable inputs utilized by the Company in determining fair values for fixed maturity investments classified as Level 3 at June 30, 2026 and December 31, 2025. Valuations for assets presented in the tables below are primarily based on broker/dealer quotes for which there is a lack of transparency as to inputs used to develop the valuations. The quantitative detail of these unobservable inputs is neither provided nor reasonably available to the Company. The weighted average yield is calculated based on fair value.
