I am excited that we will join CompassBank and extend Sandwich Co- operative Bank's branch, ATM and electronic delivery network. In an era of mega-bank consolidations, we believe that a combination with a strong, independent, community-focused institution, with an adjacent franchise, will enhance customer service, retain local jobs and enhance shareholder value. CompassBank's knowledge of our market, their heritage as an institution that services coastal communities, and their commitment to customers and employees, makes this an ideal fit." The proposed acquisition was announced by Kevin G. Champagne, President and CEO of CompassBank, and Frederic D. Legate, President and CEO of Sandwich Bancorp, and is subject to the approval of the shareholders of Sandwich Bancorp, Inc. and federal and state bank regulatory authorities, as well as other customary conditions.
