Level is calculated based on the sum of jumbo, subprime, and Alt-A mortgages from data purchased from Loan Performance TrueStandings Securities Summary report with an adjustment to estimate complete coverage. Unadjusted transactions are the change in the level, less other volume changes. Other volume changes include charge-offs beginning 2007:Q1. Gross charge-offs data are estimated by the FOF section based on data from Moody's Analytics. Data for the most recent ten years show no significant seasonality.
