[1] Related to claims from policies in which we were in a first loss position and would have paid the claim absent the rescission or denial.

[2] Related to claims from policies in which we were in a second loss position. These claims may not have resulted in a claim payment obligation absent the rescission or denial, due to deductibles and other exposure limitations included in our policies.

[3] Includes an amount related to a small number of submitted claims that were subsequently withdrawn by the insured.

[4] Projected net cumulative rescission/denial rates represent the ratio of claims rescinded or denied to claims received (by claim count). Rescissions and denials are net of actual reinstatements, plus our current estimate for expected reinstatements of previously rescinded or denied claims. These amounts represent the cumulative rates for each quarter as of September 30, 2012. Until all of the claims received during the periods shown have been internally resolved, the rescission/denial rates for each quarter will be subject to change. As discussed in footnote (2) below, these rates also will remain subject to change based on differences between estimated and actual reinstatements of previously rescinded policies or denied claims.

[5] The percentage of claims resolved for each quarter presented in the table above, represents the number of claims that have been internally resolved as a percentage of the total number of claims received for that specific quarter. A claim is considered internally resolved when it is either paid or it is concluded that the claim should be denied or rescinded, though such denials or rescissions could be challenged and, potentially reinstated or overturned, respectively. For the second and third quarters of 2012, a significant portion of claims received for those quarters have not been internally resolved; therefore, we do not believe the cumulative rescission/denial rates for those periods are presently meaningful and therefore they are not presented.
