Is your counterparty in this network?

A page tells you what OFAC published about the head. A screen tells you whether the name in front of you, with its aliases and 50%-rule owners, matches any of these entries or any of the eight lists.

A dossier screens one named counterparty across all eight lists and the 50% rule, with the evidence chain.
