Some Fine Print
- The minimum opening deposit for all our Local Impact CDs is $1,000, and the maximum amount allowed for this program is $25,000.
- As part of the CD opening process, you'll sign a pledge agreement. In signing, you're confirming your understanding that the CD is pledged as collateral for Walden Mutual's loan to the Assabet Co-op Market. In the event of a default (where the Assabet Co-op Market is unable to repay the loan), you are at risk of loss in value.
- All of our Local Impact CDs are set to automatically renew at maturity on the same term. When your 12-month Local Impact CD is approaching maturity, you'll receive a paper notice in the mail that will provide you options - including withdrawing your funds or changing the term of your Local Impact CD. If you take no action, your Local Impact CD will automatically renew on a 12-month term.
- This program is available for a limited time, and will close as of June 30th, 2025.
