My bank is in the same spot - we own a mortgage co, insurance co, title co, trust co. The Board and exec managment made a decision 2 years ago to make my department enterprise-wide in it's responsibility (pages 150-151 of the BSA/AML Manual). Yes, they will need to run 314(a) on their customers. The fortunate thing with our company is that the mortgage customers are on our main banking system, so we only have to check one place for their compliance and ours. As far as whose responsibility it is to run 314a or review procedures, that is an executive management decision. Prior to 2 years ago, each of our subsidiaries had their own processes, BSA Officer, etc. I would read carefully the pages mentioned above from the BSA/AML Manual, or pass it on to whoever the decision makers are. Also, it doesn't sound like they are running OFAC?? That is a must!
