Important Information: To help the government fight the funding of terrorism and money laundering activities,
Federal law requires all dealers in precious metals to obtain, verify, and record information
that identifies each person who opens an account.

What this means for you: If an individual, we will ask for your name, address, date of birth and other information
that will allow us to identify you. We may also ask to see your driver's license or other identifying
documents. If a company, we will ask for identifying information, to include government
registration numbers and documents, charter at formation, beneficial ownership and other information.
