Discounted Cash Flow Pricing Model Sensitivity Analysis

The estimated effect of potential changes in interest rates, credit spreads and interest rate volatility on these fair values as of such date is as follows:



	Interest Rates						Credit Spreads						Interest Rate Volatility
Factor Change		Change in fair value (in millions)				Factor change		Change in fair value (in millions)				Factor change		Change in fair value (in millions)
	+50 bps		$	(978	)		+50 bps		$	(975	)		+50 %		$	(36	)
	-50 bps		999				-50 bps		1,011				-50 %		1

The fair values of our held-to-maturity fixed-maturity securities valued by our DCF pricing model totaled $23.9 billion at March 31, 2012. The estimated effect of potential changes in interest rates, credit spreads and interest rate volatility on these fair values as of such date is as follows:



	Interest Rates						Credit Spreads						Interest Rate Volatility
Factor Change		Change in fair value (in millions)				Factor change		Change in fair value (in millions)				Factor change		Change in fair value (in millions)
	+50 bps		$	(1,488	)		+50 bps		$	(1,379	)		+50 %		$	(132	)

- Definition

Tabular disclosure of the fair value measurement of assets using significant unobservable inputs (Level 3), a reconciliation of the beginning and ending balances, separately presenting changes during the period attributable to the following: (1) total gains or losses for the period (realized and unrealized), segregating those gains or losses included in earnings (or changes in net assets) and gains or losses recognized in other comprehensive income, and a description of where those gains or losses included in earnings (or changes in net assets) are reported in the statement of income (or activities); (2) purchases, sales, issuances, and settlements (each type disclosed separately); and (3) transfers in and transfers out of Level 3 (for example, transfers due to changes in the observability of significant inputs), by class of asset.
