Put-back litigation continues to be a fight for information. Trustees might know that loans within the securitization pool are in breach, the question is whether they are willing to provide the information to investors who need it.
There are different ways to get that information. One way is the CoreLogic approach where investors basically use the firm's database to create comparisons to discover probable breaches. This approach does not give investors access to the loan files, but only provides a composite view of the files. In other words, having the composite data has allowed investors to go to the trustee and ask the trustee to look at the files to verify if there are any breaches. If the trustee refuses, then investors have ground to file a suit.
