And it’s not something that happened last week. It happened when these loans were originated, in some cases years ago. Loans have representations and warranties that have to be met. In the past, you had a certain period of time, 60 to 90 days, where you sort through these loans and, if they’re bad, you kick them back. If the do entation wasn’t correct, you’d kick it back. If you found the incomes of the buyers had been overstated, or the houses had been appraised at twice their worth, you’d kick it back. But that didn’t happen here.
And it turned out there were loan files that were missing required do entation. Part of putting the deal together is that the securitization professional, and in this case that’s banks like Goldman Sachs and JP Morgan, has to watch for this stuff. It’s called perfecting the security interest, and it’s not optional.
