Valuation Methodologies and Associated Inputs for Financial Instruments Not Carried at Fair Value

The following discussion outlines the methodologies and assumptions used to determine the fair value of our financial instruments not carried at fair value on our Consolidated Balance Sheets. Considerable judgment is required to develop these assumptions used to measure fair value. Accordingly, the estimates shown are not necessarily indicative of the amounts that would be realized in a one-time, current market exchange of all of our financial instruments.

Mortgage Loans on Real Estate

The fair value of mortgage loans on real estate is established using a discounted cash flow method based on credit rating, maturity and future income. The ratings for mortgages in good standing are based on property type, location, market conditions, occupancy, debt-service coverage, loan-to-value, quality of tenancy, borrower and payment record. The fair value for impaired mortgage loans is based on the present value of expected future cash flows discounted at the loan's effective interest rate, the loan's market price or the fair value of the collateral if the loan is collateral dependent. The inputs used to measure the fair value of our mortgage loans on real estate are classified as Level 2 within the fair value hierarchy.

Other Investments

The carrying value of our assets classified as other investments approximates fair value. Other investments include LPs and other privately held investments that are accounted for using the equity method of accounting and the carrying value is based on our proportional share of the net assets of the LPs. The inputs used to measure the fair value of our other investments are classified as Level 3 within the fair value hierarchy.

Other Contract Holder Funds

Other contract holder funds include remaining guaranteed interest and similar contracts and account values of certain investment contracts. The fair value for the remaining guaranteed interest and similar contracts is estimated using discounted cash flow calculations as of the balance sheet date. These calculations are based on interest rates currently offered on similar contracts with maturities that are consistent with those remaining for the contracts being valued. As of June 30, 2012, and December 31, 2011, the remaining guaranteed interest and similar contracts carrying value approximated fair value. The fair value of the account values of certain investment contracts is based on their approximate surrender value as of the balance sheet date. The inputs used to measure the fair value of our other contract holder funds are classified as Level 3 within the fair value hierarchy.

Short-Term and Long-Term Debt

The fair value of long-term debt is based on quoted market prices. For short-term debt, excluding current maturities of long-term debt, the carrying value approximates fair value. The inputs used to measure the fair value of our short-term and long-term debt are classified as Level 2 within the fair value hierarchy.

Financial Instruments Carried at Fair Value

We did not have any assets or liabilities measured at fair value on a nonrecurring basis as of June 30, 2012, or December 31, 2011, and we noted no changes in our valuation methodologies between these periods.

The following summarizes our financial instruments carried at fair value (in millions) on a recurring basis by the fair value hierarchy levels described in “Summary of Significant Accounting Policies” in Note 1 of our2011 Form 10-K:

• The changes in fair value of the interest rate swaps are offset by an adjustment to derivative investments (see Note 5).
• Transfers in or out of Level 3 for AFS and trading securities are displayed at amortized cost as of the beginning-of-period. For AFS and trading securities, the difference between beginning-of-period amortized cost and beginning-of-period fair value was included in OCI and earnings, respectively, in prior periods.
• Amortization and accretion of premiums and discounts are included in net investment income on our Consolidated Statements of Comprehensive Income (Loss). Gains (losses) from sales, maturities, settlements and calls and OTTI are included in realized gain (loss) on our Consolidated Statements of Comprehensive Income (Loss).
• Gains (losses) from sales, maturities, settlements and calls are included in realized gain (loss) on our Consolidated Statements of Comprehensive Income (Loss).
• The changes in fair value of the credit default swaps andcontingency forwards are included in realized gain (loss) on our Consolidated Statements of Comprehensive Income (Loss).
• Deferrals and subsequent changes in fair value for the participants' investment options are reported in commissions and other expenses on our Consolidated Statements of Comprehensive Income (Loss).
• Gains (losses) from sales, maturities, settlements and calls are included in net investment income on our Consolidated Statements of Comprehensive Income (Loss).

Transfers in and out of Level 3 are generally the result of observable market information on a security no longer being available or becoming available to our pricing vendors. For the three andsixmonths ended June 30, 2012 and 2011, our corporate bonds transfers in and out were attributable primarily to the securities' observable market information no longer being available or becoming available, respectively. Transfers in and out of Levels 1 and 2 are generally the result of a change in the type of input used to measure the fair value of an asset or liability at the end of the reporting period. When quoted prices in active markets become available or when these prices become unavailable, but we are able to employ a valuation methodology using significant observable inputs, transfers between Levels 1 and 2 will result. For the three andsix months ended June 30, 2012 and 2011, the transfers between Levels 1 and 2 of the fair value hierarchy were less than $1 million for our financial instruments carried at fair value.

The following summarizes the fair value (in millions), valuation techniques and significant unobservable inputs of the Level 3 fair value measurements that were developed as of June 30, 2012:

					Fair		Valuation	Significant
					Value		Technique	Unobservable Inputs	Range

						Wait period (5)		0 - 25 years (or
								years until the
								eligible age)
						Percent of maximum
							withdrawal amount (6)	95.0% - 100.0%
						Non-performance risk ("NPR") (7)		0.22% - 0.55%
						Mortality rate (3)		(8)
						Volatility (4)		1.0% - 35.0%

• The liquidity/duration adjustment input represents an estimated market participant composite of adjustments attributable to liquidity premiums, expected durations, structures and credit quality that would be applied to the market observable information of an investment.
• The lapse rate input represents the estimated probability of a contract surrendering during a year, and thereby forgoing any future benefits. The range represents the lapse rates during the surrender charge period for indexed annuity contracts.
• The mortality rate input represents the estimated probability of when an individual belonging to a particular group, categorized according to age or some other factor such as occupation, will die.
• The volatility input represents overall volatilities assumed for the underlying variable annuity funds, which include a mixture of equity and fixed income assets. Fair value of the variable annuity GLB embedded derivatives would increase if higher volatilities were used for valuation.
• The wait period input represents the estimated period a contract holder would wait to withdraw after becoming eligible.
• The percent of maximum withdrawal amount input represents the estimated ratio of contract withdrawal amount to the maximum withdrawal amount specified.
• The NPR input represents the estimated additional credit spread that market participants would apply to the market observable discount rate when pricing a contract.
• Based on the “Annuity 2000 Mortality Table” developed by the Society of Actuaries Committee on Life Insurance Research that was adopted by the National Association of Insurance Commissioners in 1996 for our mortality input.

From the table above, we have excluded Level 3 fair value measurements obtained from independent, third-party pricing sources. We do not develop the significant inputs used to measure the fair value of these assets and liabilities, and the information regarding the significant inputs is not readily available to us. Independent broker-quoted fair values are non-binding quotes developed by market makers or broker-dealers obtained from third-party sources recognized as market participants. The fair value of a broker-quoted asset or liability is based solely on the receipt of an updated quote from a single market maker or a broker-dealer recognized as a market participant as we do not adjust broker quotes when used as the fair value measurement for an asset or liability. Significant increases or decreases in any of the quotes received from a third-party broker-dealer may result in a significantly higher or lower fair value measurement.

Changes in any of the significant inputs presented in the table above may result in a significant change in the fair value measurement of the asset or liability as follows:

• Investments – An increase in the liquidity/duration input would result in a decrease in the fair value measurement.

• Indexed annuity contracts embedded derivatives – An increase in the lapse rate or mortality rate inputs would result in a decrease in the fair value measurement.
• GLB reserves embedded derivatives– An increase in our lapse rate, wait period, NPR or mortality rate inputs would result in a decrease in the fair value measurement. An increase in the percent of maximum withdrawal amountinput would result in an increase in the fair value measurement.

For each category discussed above, the unobservable inputs are not inter-related; therefore, a directional change in one input will not affect the other inputs.

As part of our on-going valuation process, we assess the reasonableness of our valuation techniques or models and make adjustments as necessary. For more information, see “Summary of Significant Accounting Policies” in Note 1 of our 2011 Form 10-K.
