Important Information Regarding Bank Secrecy Act (BSA) Changes:

Starting May 11, 2018, changes have been made to the Bank Secrecy Act.  The Bank Secrecy Act is a U.S. law requiring financial institutions to assist government agencies to detect and prevent money laundering.

The changes to BSA will require all financial institutions to verify the identity of “Beneficial Owners” of certain “Legal Entities”.  This applies EACH time any account is opened or renewed.

We are required to ask you for identifying information (name, address, date of birth, and social security number), as well as personal identification documentation for:

  • EACH individual that has 25% or more Beneficial Ownership in the Legal Entity; and
  • ONE individual that has Significant Managerial Control of the Legal Entity such as Chief Executive Officer, Chief Financial Officer, President, Vice President, Managing Member, etc.

If you are opening an account on behalf of a covered Legal Entity, you will be required to provide appropriate documentation and to certify that this information is true and accurate to the best of your knowledge.  In order to make this process as efficient as possible, we recommend that you obtain the above information, along with a copy of the current Driver’s License for EACH identified individual.

Thank you for placing your continued trust in Bank of Sun Prairie.  We are grateful for your business and look forward to continuing to work together!
