Dec. 31, 2019

The assets and liabilities measured at estimated fair value on a recurring basis and their corresponding placement in the fair value hierarchy are presented below. Investments that do not have a readily determinable fair value and are measured at net asset value (or equivalent) as a practical expedient to estimated fair value are excluded from the fair value hierarchy.

Fair Value Inputs, Quantitative Information

The following table presents certain quantitative information about the significant unobservable inputs used in the fair value measurement, and the sensitivity of the estimated fair value to changes in those inputs, for the more significant asset and liability classes measured at fair value on a recurring basis using significant unobservable inputs (Level 3) at:



					December 31, 2019			December 31, 2018			Impact of Increase in Input on Estimated Fair Value
	Valuation Techniques		Significant Unobservable Inputs		Range			Range			Impact of Increase in Input on Estimated Fair Value
Embedded derivatives
Direct, assumed and ceded guaranteed minimum benefits	•	Option pricing techniques	•	Mortality rates	0.02%	-	11.31%	0.02%	-	11.31%	Decrease (1)
			•	Lapse rates	0.25%	-	16.00%	0.25%	-	16.00%	Decrease (2)
			•	Utilization rates	0.00%	-	25.00%	0.00%	-	25.00%	Increase (3)
			•	Withdrawal rates	0.25%	-	10.00%	0.25%	-	10.00%	(4)
			•	Long-term equity volatilities	16.24%	-	21.65%	16.50%	-	22.00%	Increase (5)
			•	Nonperformance risk spread	0.54%	-	1.99%	1.91%	-	2.66%	Decrease (6)

_______________


(1)	Mortality rates vary by age and by demographic characteristics such as gender. The range shown reflects the mortality rate for policyholders between 35 and 90 years old, which represents the majority of the business with living benefits. Mortality rate assumptions are set based on company experience and include an assumption for mortality improvement.

(2)

The range shown reflects base lapse rates for major product categories for duration 1-20, which represents majority of business with living benefit riders. Base lapse rates are adjusted at the contract level based on a comparison of the actuarially calculated guaranteed values and the current policyholder account value, as well as other factors, such as the applicability of any surrender charges. A dynamic lapse function reduces the base lapse rate when the guaranteed amount is greater than the account value as in-the-money contracts are less likely to lapse. Lapse rates are also generally assumed to be lower in periods when a surrender charge applies.

(3)

The utilization rate assumption estimates the percentage of contract holders with a GMIB or lifetime withdrawal benefit who will elect to utilize the benefit upon becoming eligible in a given year. The range shown represents the floor and cap of the GMIB dynamic election rates across varying levels of in-the-money. For lifetime withdrawal guarantee riders, the assumption is that everyone will begin withdrawals once account value reaches zero which is equivalent to a 100% utilization rate. Utilization rates may vary by the type of guarantee, the amount by which the guaranteed amount is greater than the account value, the contract’s withdrawal history and by the age of the policyholder.

(4)

The withdrawal rate represents the percentage of account balance that any given policyholder will elect to withdraw from the contract each year. The withdrawal rate assumption varies by age and duration of the contract, and also by other factors such as benefit type. For any given contract, withdrawal rates vary throughout the period over which cash flows are projected for purposes of valuing the embedded derivative. For GMWBs, any increase (decrease) in withdrawal rates results in an increase (decrease) in the estimated fair value of the guarantees. For GMABs and GMIBs, any increase (decrease) in withdrawal rates results in a decrease (increase) in the estimated fair value.


(5)	Long-term equity volatilities represent equity volatility beyond the period for which observable equity volatilities are available. For any given contract, long-term equity volatility rates vary throughout the period over which cash flows are projected for purposes of valuing the embedded derivative.

(6)

Nonperformance risk spread varies by duration. For any given contract, multiple nonperformance risk spreads will apply, depending on the duration of the cash flow being discounted for purposes of valuing the embedded derivative.

(1)	Comprised of U.S. and foreign corporate securities.


(2)	Freestanding derivative assets and liabilities are presented net for purposes of the rollforward.


(3)	Embedded derivative assets and liabilities are presented net for purposes of the rollforward.


(4)	Investment performance related to separate account assets is fully offset by corresponding amounts credited to contract holders within separate account liabilities. Therefore, such changes in estimated fair value are not recorded in net income (loss). For the purpose of this disclosure, these changes are presented within net investment gains (losses).

(5)

Amortization of premium/accretion of discount is included within net investment income. Impairments charged to net income (loss) on securities are included in net investment gains (losses). Lapses associated with net embedded derivatives are included in net derivative gains (losses). Substantially all realized/unrealized gains (losses) included in net income (loss) for net derivatives and net embedded derivatives are reported in net derivative gains (losses).


(6)	Interest and dividend accruals, as well as cash interest coupons and dividends received, are excluded from the rollforward.


(7)	Items purchased/issued and then sold/settled in the same period are excluded from the rollforward. Fees attributed to embedded derivatives are included in settlements.


(8)	Gains and losses, in net income (loss) and OCI, are calculated assuming transfers into and/or out of Level 3 occurred at the beginning of the period. Items transferred into and then out of Level 3 in the same period are excluded from the rollforward.

(9)

Changes in unrealized gains (losses) included in net income (loss) relate to assets and liabilities still held at the end of the respective periods. Substantially all changes in unrealized gains (losses) included in net income (loss) for net derivatives and net embedded derivatives are reported in net derivative gains (losses).
