Interest Compounding
Interest will be compounded monthly. Interest will be credited to your account on the first day of each month for the month prior. If you close your account before interest is credited, you will not receive the accrued interest. The Bank uses the daily balance method to calculate the interest on your account. This method applies a daily periodic rate to the end of day balance in the account each day. Interest will begin to accrue no later than the business day we receive provisional credit for the deposit of noncash items (for example, checks) into your Increase Deposit Account.
