The continuing activity report may contain the same limited content as the initial SAR,plus details about the amount of deposits, withdrawals, and transfers in the account since the last SAR. However, if, in the course of conducting customer due diligence(including
ongoingmonitoring for red flags), the financial institution detects changes in activity that potentially implicate one of the Cole Memopriorities or violate state law,the financial institution should file a “Marijuana Priority” SAR
