[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.
