Our exam was completed in May using the SMAART guidelines. At this point there isn't much you can do to prepare. However, I can tell you that they are looking for a system of controls wherein the bank is able to review, identify and resolve regulatory issues. Once the examiners arrive they basically review your work papers and verify the system is functioning properly. Compliance Management and accountability are also under the magnifying glass. I will say that the team conducting our exam were some of the most affable with which I have ever worked.
Before I forget, Bank Secrecy and Flood were two very HOT topics. I would make sure those two areas are in order prior to their arrival.
Good Luck. I hope your exam goes smoothly for you.
