John, let me ask you this- if during the course of originating a loan, the customer does not produce all proper documentation requested, including recent financial statements- would you say that activity would lead to open an investigation,,, and potentially a SAR?
It's been a while since I've done any lending (I decided I had a hard time saying "No!"), but I don't think that failure to provide all the requested documentation for underwriting (such as financial statements) would call, per se, for a SAR investigation. Some people don't have current financials, some don't want to give out the information (even though they know it will be asked for by a lender). But if anything in the documents turns out to be fraudulently omitted or misstated, I'd get my SAR pencil and notebook out.
