Let's just say that at a ficticious bank
there is someone in charge of CTR filings. Just for an example lets say that person went through the large cash transaction report and repeatly marked a customer as exempt when they were in fact not exempt.
At this ficticious bank they went back to January 1,2005 and since that time their had been no CTR reportable transactions. How far back should this bank look to see if they might have accidentally missed filing a CTR for this customer?
