It is important to understand why we are requesting this information.

All financial institutions have an increased obligation to maintain current customer information and periodically confirm that information. The more we know about our customers and their banking habits, the better we can identify potential unusual activity.

Financial institutions have been asked to play a more significant role in the battle against money laundering and we are proudly doing our part.

What is money laundering?

  • The illegal process of concealing the identity, source and destination of illicitly obtained money.
  • The magnitude of the problem has been estimated to be over $800 billion per year, creating a sizable threat to the government, economy and people in the U.S. and in countries around the world.

The importance of Know Your Customer (KYC)

  • Federal regulations require that all financial institutions employ KYC screening as part of their ongoing anti-money laundering measures.
  • Knowing more about who we do business with can prevent us from inadvertently facilitating money laundering.
  • KYC enables us to better serve all our customers.

Help us serve you better

  • Knowing our customers has always been a top priority -- it's integral to the way we do business. 
  • We strive to get to know you and your banking practices and habits which, in turn, help us validate account holder information and better understand how the account will be used. 
  • Completing periodic reviews of your information is important to protect and service your banking relationship. 

We are serious about preventing financial crime

  • Money laundering and financial crime remain serious threats to individuals, businesses and our economy.
  • Ensuring your information is accurate, complete and verified on a periodic basis is part of this process.
