Minimum balance to earn APY is $0.01. Fees or withdrawals could reduce the Annual Percentage Yield (APY) on the above accounts. Disclosures on fees, transaction limitations and other product features are contained in our Consumer Deposit Account Fee Schedule, applicable Product Information Brochure, and our Terms and Conditions.
Automatically renewable CDs will renew for an identical term at maturity unless you specify a different available renewal term in writing. You have 10 days upon maturity to withdraw these funds if desired.
Non-renewable CDs will not automatically renew at maturity. If you do not renew your account on the certificate maturity date, your funds will be placed in a non-interest-bearing account.
CD transaction limitations: You cannot make additional deposits to a CD during a term and cannot withdraw principal from a CD without our consent except on or after maturity. Automatically renewable CD accounts will have a 10-day grace period after each renewal date during which withdrawals are permitted without penalty.
Withdrawing principal from a CD prior to maturity without consent from Bank of Sun Prairie will result in an early withdrawal penalty.
