Infinity Credit Union (Infinity CU) recently added a 13-month Share Certificate earning 5.00% APY to its product line. The 13-month Share Certificate can be open with a $500 minimum deposit, with no stated balance cap.

As stated in the Truth-in-Savings disclosure (page 36), the Early Withdrawal Penalty reads as follows:

If the term of the certificate is between one hundred eighty (180) days and three (3) years, the forfeiture is an amount equal to three (3) months’ dividends, whether earned or not, calculated on the principal amount.

If the account has not yet earned enough dividends or if the dividend has already been paid, the penalty will be deducted from the principal.

For an IRA Certificate, a $50.00 penalty is imposed for closing an IRA certificate before the maturity date.
