[1] Includes derivative instruments in a net positive fair value position after consideration of the accrued interest and impact of collateral posting requirements which may be imposed by agreements and applicable law. See footnote 2 to this table for derivative liabilities.

[2] Includes derivative instruments in a net negative fair value position (derivative liability) after consideration of the accrued interest and impact of collateral posting requirements which may be imposed by agreements and applicable law.

Fair Value Inputs, Assets, Quantitative Information

Significant Unobservable Inputs for Level 3 - Securities
Assets accounted for at fair value on a recurring basis	Fair Value		Predominant Valuation Technique	Significant Unobservable Input	Minimum	Maximum	Weighted Average [1]	Impact of Increase in Input on Fair Value [2]
As of March 31, 2019
CLOs [3]	$	93	Discounted cash flows	Spread	256 bps	256 bps	256 bps	Decrease
CMBS [3]	$	2	Discounted cash flows	Spread (encompasses prepayment, default risk and loss severity)	9 bps	1,040 bps	180 bps	Decrease
Corporate [4]	$	294	Discounted cash flows	Spread	121 bps	656 bps	213 bps	Decrease
RMBS [3]	$	725	Discounted cash flows	Spread [6]	21 bps	407 bps	78 bps	Decrease
				Constant prepayment rate [6]	—%	16%	6%	Decrease [5]
				Constant default rate [6]	1%	6%	3%	Decrease
				Loss severity [6]	—%	100%	62%	Decrease
As of December 31, 2018
CMBS [3]	$	2	Discounted cash flows	Spread (encompasses prepayment, default risk and loss severity)	9 bps	1,040 bps	182 bps	Decrease
Corporate [4]	$	274	Discounted cash flows	Spread	145 bps	1,175 bps	263 bps	Decrease
RMBS [3]	$	815	Discounted cash flows	Spread [6]	12 bps	215 bps	86 bps	Decrease
				Constant prepayment rate [6]	1%	15%	6%	Decrease [5]
				Constant default rate [6]	1%	8%	3%	Decrease
				Loss severity [6]	—%	100%	61%	Decrease

[1] The weighted average is determined based on the fair value of the securities.

[2] Conversely, the impact of a decrease in input would have the opposite impact to the fair value as that presented in the table.

[3] Excludes securities for which the Company bases fair value on broker quotations.

[4] Excludes securities for which the Company bases fair value on broker quotations; however, included are broker priced lower-rated private placement securities for which the Company receives spread and yield information to corroborate the fair value.

[5] Decrease for above market rate coupons and increase for below market rate coupons.

[6]

Generally, a change in the assumption used for the constant default rate would have been accompanied by a directionally similar change in the assumption used for the loss severity and a directionally opposite change in the assumption used for constant prepayment rate and would have resulted in wider spreads.

Significant Unobservable Inputs for Level 3 - Derivatives
	Fair Value		Predominant Valuation  Technique	Significant Unobservable Input	Minimum		Maximum		Weighted Average [1]		Impact of  Increase in Input on  Fair Value [2]
As of March 31, 2019
Equity Options	$	1	Option model	Equity volatility	12	%	20	%	18	%	Increase
As of December 31, 2018
Interest rate swaptions [3]	$	1	Option model	Interest rate volatility	3	%	3	%	3	%	Increase
Equity options	$	3	Option model	Equity volatility	19	%	21	%	20	%	Increase

[1] The weighted average is determined based on the fair value of the derivatives.

[2] Conversely, the impact of a decrease in input would have the opposite impact to the fair value as that presented in the table. Changes are based on long positions, unless otherwise noted. Changes in fair value will be inversely impacted for short positions.

[3]

The swaptions presented are purchased options that have the right to enter into a pay-fixed swap.

[3] Transfers in and/or (out) of Level 3 are primarily attributable to the availability of market observable information and the re-evaluation of the observability of pricing inputs.

[4] Derivative instruments are reported in this table on a net basis for asset (liability) positions and reported in the Condensed Consolidated Balance Sheets in other investments and other liabilities.
