Depositors Insurance Fund

Established by the Massachusetts legislature in 1934, the Depositors Insurance Fund (DIF) is a private, industry-sponsored insurance fund that insures all deposit accounts above Federal Deposit Insurance Corporation (FDIC) limits at its member banks.

The unique combined insurance coverage afforded by the FDIC and the DIF ensures deposit balances are fully protected.

Since the DIF was established, no depositor has ever lost a penny in any Massachusetts savings or cooperative bank.

Cornerstone Bank donation supports YMCA of Central Massachusetts

Published on May 27, 2025

Cornerstone Bank has donated $25,000 to the YMCA of Central Massachusetts for the fifth year straight. The money will support programs that build academic skills and help kids develop as future leaders.

“The YMCA is a place where children form lasting positive relationships with peers and mentors,” said Cornerstone CEO Todd Tallman. “We’ve seen how powerful that can be.”

Thousands of teenagers attend the YMCA of Central Massachusetts’ many programs every year, including summer camp, after-school activities, internships, food assistance, education, mental health assistance and programs for cancer survivors. Cornerstone Bank’s donation will help ensure that children continue to have access to these life-changing programs regardless of their financial means.

“The Y gives children the tools they need to develop into healthy and socially responsible leaders,” said Tallman. “We’re proud to have a small part in uplifting that important mission.”
