The following discussion mainly focuses on our direct primary RIF , which represents approximately 94.5% of our total mortgage insurance RIF at December 31, 2012. For additional information regarding our pool and non-traditional mortgage insurance RIF, see “—Business—Mortgage Insurance—Business—T raditional Risk” and “—Business—Mortgage Insurance— Business— Non-Traditional Risk .” 

We analyze our portfolio in a number of ways to identify any concentrations or imbalances in risk dispersion. We believe the performance of our mortgage insurance portfolio is af fected significantly by: 

• general economic conditions (in particular home prices and unemployment); 

• the age of the loans insured; 

• the geographic dispersion of the properties securing the insured loans and the condition of the housing market; 

• the quality of underwriting decisions at loan origination; and 

• the characteristics of the loans insured (including loan-to-value (“L TV”), purpose of the loan, type of loan instrument and type of underlying property securing the loan).
