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 September 30, 2019
CLOs [3] | $ | 225 |  | Discounted cash flows | Spread | 235 bps | 244 bps | 240 bps | Decrease
CMBS [3] | $ | 11 |  | Discounted cash flows | Spread (encompasses prepayment, default risk and loss severity) | 9 bps | 1,832 bps | 197 bps | Decrease

|  |  | Constant default rate [6] | 1% | 5% | 3% | Decrease
|  |  | Loss severity [6] | —% | 100% | 72% | 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

|  |  | 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 September 30, 2019
Equity options | $ | (5 | ) | Option model | Equity volatility | 11 | % | 25 | % | 15 | % | Increase
As of December 31, 2018

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.
