I can speak on this since we are in the middle of an exam and the examiners made us change a huge number of revenue codes from 1 to 3. This was because we accept what the borrower tell us verbally and don't require them to always provide new financial info. This is on certain loans with very established borrowers. The reg says we don't have to verify but the regulator says we do. Anyway, we were told that the number of NA/3 shouldn't affect our rating because we can show it is a low/doc program we offer. These are primarily rural ag or small biz loans with tons of collateral.
We do have another small business program that is also low/doc but the borrower does write the revenues on the application. The regulator wasn't going to count that at first but since it is in writing and signed by the borrower as true, we are not having to change those.
Like Rizzo says, address it up front.
