In my audit reports, I try to give a brief breakdown of the reg that I've just audited. Some are very brief, maybe 2 sentences. Others, such as BSA, may be a couple of paragraphs. I find that this helps when discussing the report, as the Board has some understanding to why I am looking at something. I find that they are asking better questions now. It also helps to document the training, since it is part of the Board package and is filed with the minutes. Our FDIC examiner liked it and that's all that matters.
(not really, but it sure helps!)
