Notifying Board of Directors of SAR Filings
Banks are required by the SAR regulations of their federal banking agency to notify the board of directors or an appropriate board committee that SARs have been filed. However, the regulations do not mandate a particular notification format and banks should have flexibility in structuring their format. Therefore, banks may, but are not required to, provide actual copies of SARs to the board of directors or a board committee. Alternatively, banks may opt to provide summaries, tables of SARs filed for specific violation types, or other forms of notification. Regardless of the notification format used by the bank, management should provide sufficient information on its SAR filings to the board of directors or an appropriate committee in order to fulfill its fiduciary duties, while being mindful of the confidential nature of the SAR.
Note, reporting SARs to the board is required by your regulatory agency, not the BSA or FinCEN. I'm sure that FinCEN thinks its the stupidest thing a bank could do. So does the ABA based on their published comments. The amount of detail provided is only an issue in community banks. Mega banks just report the activity to the board of directors in charts and graphs.
