You should not reference either document in an SAR filing.
"Due to the confidentiality of grand jury proceedings, if a bank files a SAR after receiving a grand jury subpoena, law enforcement discourages banks from including any reference to the receipt or existence of the grand jury subpoena in the SAR. Rather, the SAR should reference only those facts and activities that support a finding of suspicious transactions identified by the bank."
"If a bank files a SAR after receiving a NSL, the SAR should not contain any reference to the receipt or existence of the NSL. The SAR should reference only those facts and activities that support a finding of unusual or suspicious transactions identified by the bank."
