Summary of Balance of Subrogation Recoveries and Related Claim Liabilities, by Estimation Approach

The balance of subrogation recoveries and the related claim liabilities, by estimation approach, at September 30, 2012 and December 31, 2011, are as follows:

Approach	Count⁽²⁾		Gross claim liability before subrogation recoveries		Subrogation recoveries⁽¹⁾			Gross claim liability after subrogation recoveries
Adverse samples		28	$	2,734,471	$	(1,508,150	)	$	1,226,321
Random samples		16		1,157,305		(1,180,717	)		(23,412	)

Totals		44	$	3,891,776	$	(2,688,867	)	$	1,202,909

The amount of recorded subrogation recoveries related to each securitization is limited to ever-to-date paid losses plus the present value of projected future paid losses for each policy. To the extent significant losses have been paid but not yet recovered, the recorded amount of subrogation recoveries may exceed the expected future claims for a given policy. The net cash inflow for these policies is recorded as a “Subrogation recoverable” asset. For those transactions where the subrogation recovery is less than expected future claims, the net cash outflow for these policies is recorded as a “Loss and loss expense reserve” liability. Of the $2,688,867 of subrogation recoveries recorded at September 30, 2012, $785,519 was included in “Subrogation recoverable” and $1,903,348 was included in “Loss and loss expense reserves.” Of the $2,720,266 of subrogation recoveries recorded at December 31, 2011, $829,469 was included in “Subrogation recoverable” and $1,890,797 was included in “Loss and loss expense reserves.”

The sponsor’s repurchase obligation may differ depending on the terms of the particular transaction and the status of the specific loan, such as whether it is performing or has been liquidated or charged off. The estimated subrogation recovery for these transactions is based primarily on loan level data provided through trustee reports received in the normal course of our surveillance activities or provided by the sponsor. While this data may not include all the components of the sponsor’s contractual repurchase obligation we believe it is the best information available to estimate the subrogation recovery.

Other changes which may impact subrogation recoveries include changes in actual or projected collateral performance and/or the projected timing of recoveries. For the nine months ended September 30, 2012, two transactions were removed from the Adverse Sample subrogation population; however, the impacts on RMBS subrogation disclosed in the Adverse Sample column relate to multiple transactions.
