For eligible accounts, the 1st of the 4 Introductory Fixed Bonus Interest periods will begin in the calendar month that your account has been opened. Interest for the 1st period will be calculated from the day the account is opened until the end of that calendar month. For example, an account opened on the 15th of April will have Introductory Fixed Bonus Interest calculated for the months of April, May, June and July as long as the member is eligible, and the Bonus Interest Criteria is met for these months. In this scenario, the interest for the month of April will be calculated from 15/04 – 30/04.
