Just finishing up this SAR. Does everyone agree that the subjects are the payee of the check and the employee that honored his request to change the amount of the check?
That's really up to you, as SAR filing is subjective; the most important thing is that you justify and document your conclusions relative to each transaction party's degree of involvement within the narrative. Reason being, I have heard many a horror story of banks receiving findings for not including
every financial party linked to a suspicious transaction as a subject unless they were a confirmed victim. While I disagree with those findings, the point remains that it's in your best interest to explain your basis for including or not including as a subject anyone that could
reasonably considered one.
Personally, I would put the CPA, check issuer, and the payee as
subjects. Remember - "Subject" does not equal "Suspect." I acknowledge that most folks would disagree with that recommendation; however, I tend to employ a minimax strategy towards all aspects of SAR filing.
As others have indicated - additional review may be appropriate. Make sure your investigation goes back a reasonable amount of time to determine if any other checks were issued to the same payee, as that may give you a better idea of how involved the CPA is in structuring the checks. If the payee received multiple checks in a short time frame, that could solidify the role of the CPA. Make sure you also evaluate the source of funds for the payment and determine why the payment was issued.
If you conclude the CPA is involved beyond having his name on the checks, you should reconsider the relationship.
