Significant Unobservable Inputs

The following tables present quantitative information about the significant unobservable inputs utilized in the fair value measurement of Level 3 assets. Valuations for assets and liabilities not 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 unobservable inputs from these broker quotes is neither provided nor reasonably available. The weighted average rate is calculated based on fair value.

September 30, 2022	Estimated Fair Value		Valuation Techniques	Unobservable Inputs	Range (Weighted Average)
	(In millions)
Fixed maturity securities	$	1,111	Discounted cash flow	Credit spread	1%	—	11%	(3%)

Financial Assets and Liabilities Not Measured at Fair Value

The carrying amount, estimated fair value and the level of the fair value hierarchy of the financial assets and liabilities which are not measured at fair value on the Consolidated Condensed Balance Sheets are presented in the following tables. The carrying amounts and estimated fair values of short term debt and long term debt exclude finance lease obligations. The carrying amounts reported on the Consolidated Condensed Balance Sheets for cash and short term investments not carried at fair value and certain other assets and liabilities approximate fair value due to the short term nature of these items.
