If a corporate resolution states that only one signature is required to open a deposit account or a CD on behalf of the corporation — regardless of the number of authorized signers listed in the resolution — does that mean any one of the authorized signers can come into the bank and sign the CD agreement on behalf of the corporation?

Yes, we believe that if customer with multiple authorized signers has a corporate resolution authorizing any of the authorized signers to open a certificate of deposit (CD) account, any one of the authorized signers may sign a CD account agreement on behalf of the customer — provided that this would not be inconsistent with the terms of your account agreement and any other agreement you may have defining the scope of the authorized signers’ authority.
