We are OCC too. We had a fair lending examination a few years ago. The examiner said that our name was randomly selected - like we won the lottery! I was freaked out!
However, it was very limited scope. One examiner and he seemed annoyed that he had to do the exam. He looked at the HMDA LAR. Pulled only a few files. They have since changed their process and do a fair lending risk assessment everytime they are here.
Good luck. Have you conducted your own fair lending risk assessment?
