Loss Reserves [Abstract]

Loss Reserves

We establish reserves to recognize the estimated liability for losses and loss adjustment expenses ("LAE") related to defaults on insured mortgage loans. Loss reserves are established by estimating the number of loans in our inventory of delinquent loans that will result in a claim payment, which is referred to as the claim rate, and further estimating the amount of the claim payment, which is referred to as claim severity.

Estimation of losses is inherently judgmental. The conditions that affect the claim rate and claim severity include the current and future state of the domestic economy, including unemployment, and the current and future strength of local housing markets. Current conditions in the housing and mortgage industries make these assumptions more volatile than they would otherwise be. The actual amount of the claim payments may be substantially different than our loss reserve estimates. Our estimates could be adversely affected by several factors, including a further deterioration of regional or national economic conditions, including unemployment, leading to a reduction in borrowers' income and thus their ability to make mortgage payments, and a further drop in housing values that could result in, among other things, greater losses on loans that have pool insurance, and may affect borrower willingness to continue to make mortgage payments when the value of the home is below the mortgage balance and mitigation from rescissions being materially less than assumed. Changes to our estimates could result in a material impact to our results of operations and capital position, even in a stable economic environment.
