This disclosure contains information about terms, fees, and interest rates for some of the accounts we offer.

Rate Information

This account is an interest bearing account. The interest rate and annual percentage yield are included in the Rate Chart. The interest rate and annual percentage yield will not change for the term of the account. The interest rate will be in effect for a period of 90 days or less. Interest begins to accrue on the business day you deposit noncash items (for example, checks). Interest will be compounded and credited on the account. Interest will be credited at maturity. We will mail the interest in a check to you, interest will be added to the principal, or deposit the interest in an account that you designate.

Balance Information

We use the daily balance method to calculate the interest on the account. This method applies a daily periodic rate to principal in the account each day.

You must deposit $500.00 to open this account. You may not make additional deposits into this account. You may not make withdrawals from this account until the maturity date.

Time Account Information

Your account will mature in a period of 90 days or less. The annual percentage yield assumes interest will remain on deposit until maturity. A withdrawal will reduce earnings. If you withdraw any of the principal before the maturity date, we will impose a penalty of an amount that would have been earned at the simple interest rate for the full term of the CD. This account will automatically renew. You will have 10 days after the maturity to withdraw funds without penalty.
