Hypothetical
You are a compliance manager in the United States at a major U.S. bank that operates internationally.
A compliance analyst on your team flags a pending $2,500 payment for your review because the payment appears to involve a Specially Designated National (“SDN”), Gaston Tomaghelli.
The pending payment was originally automatically flagged in the bank’s systems as a potential sanctions hit because of the presence of the name “Tomaghelli” in the related payment documentation.
The compliance analyst manually reviewed the flagged pending payment and escalated it to you for further review. 
Based on your initial review of the information available, it appears one of the bank’s U.S. customers (the originator) is attempting to send money to Tomaghelli (the beneficiary).
