Note: FICO and LTV primarily at origination. First mortgage table excludes First Collateral Services ($1.5 billion Commercial Business Group portfolio). Tables exclude $4.6 billion from first mortgages and $0.8 billion from second mortgages for which FICO and LTV data was unavailable. 90+DPD delinquency rate for the excluded first mortgages is 2.02% (vs. 2.69% for total portfolio) and 1.02% for the excluded second mortgages (vs. 1.26% for total portfolio). Excluding Government insured loans (described below), the 90+DPD delinquency rate for the first mortgage portfolio is 1.99%. Considering current market and economic conditions, LTV ratios and FICO scores may have deteriorated.
