In this example the conductor only has role on one account. We have aggressive aggregation settings on our software but it can only aggregate what there is two data points for.
My bank already has around 35,000 reportable transactions each year. Management has no appetite to lower the threshold. Lacking a specific definition of has knowledge, it would really take an exam finding to move in the direction of gathering conductor information at lower levels. What that finding would be based on is unclear to me or how the missed CTRs would be identified is unclear. I would like to resolve the issue before it ever got to that point, but I can't make factual argument.
In the situation where you gather conductor information at all levels, are you then going back and aggregating that information daily looking for common conductors? For us that would be a few thousand transactions each day, plus deciphering and aggregating ATM conductors.
It seems like CTRs can potentially have an near infinite level of depth and the line just has to be drawn somewhere.
I think some tellers would remember and some wouldn't. If I was a teller, I don't think I would remember every person that comes in. I have to check my calendar sometimes to remember who I had an hour long meeting with sometimes
