As of the November distribution date, the most seasoned of these deals (series 2002-11) has a pool factor (mortgage principal outstanding as a percentage of original mortgage principal as of closing) of 10% and currently benefits from CE levels more than eight times original levels. The least seasoned transaction (series 2003-19) has a pool factor of 83% and has experienced slight increases in CE levels.

All of the Wells Fargo transactions are secured by 15- and/or 30-year fixed-rate, adjustable rate, and hybrid mortgages extended to prime quality borrowers.
