[1] Includes a small number of submitted claims that were subsequently withdrawn by the insured.

[2] 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.

[3] Related to claims from policies in which we were in a second loss position. These rescissions or denials may not have resulted in a claim payment obligation due to deductibles and other exposure limitations included in our policies.

[4] Rescission/Denial rates represent the ratio of claims rescinded or denied to claims received (by claim count) and represent (as of September 30, 2011) the cumulative rate for each quarter based on number of claims received during that quarter. Until all of the claims received during the periods shown have been internally resolved, the rescission rates for each quarter will be subject to change. These rates also will remain subject to change based on reinstatements of previously rescinded policies or denied claims.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A claim is considered internally resolved when it is either paid or it is concluded that the claim should be denied or rescinded, though such denials or rescissions could be challenged and, potentially reinstated. For the second and third quarters of 2011, a significant portion of claims received for those quarters have not been internally resolved; therefore, we do not believe the cumulative rescission rates for those periods are presently meaningful.
