This document summarizes mortgage insurance delinquency rates from the 4th quarter of 2007 to the 1st quarter of 2008. It shows that default rates increased across most categories, with the highest default rates for loans with lower FICO scores, higher LTV ratios, or riskier loan types like ARMs, Alt-A, interest-only and option ARMs. Default rates on fixed rate loans and for borrowers with stronger credit (FICO over 660) also rose during this period but remained lower than other groups.
