Deposit/Savings
You must maintain the minimum balance needed for each tier in order to earn the Annual Percentage Yield (APY) disclosed. All rates and APYs are subject to change after the account is opened. Fees could reduce earnings on the account. Interest rates currently offered on all deposit accounts are determined at the bank's discretion and may change daily. We use the daily balance method to calculate interest on all deposit accounts. This method applies a daily periodic rate to the principal in the account each day. Interest on your check deposit begins to accrue on the business day we receive credit for the deposit on all accounts. Interest will be compounded daily and credited to your account monthly for all checking and savings accounts.
Certificate of Deposits
Annual Percentage Yield (APY) assumes principal and interest remain on deposit for the term of the certificate. Interest is compounded daily. All interest payments for the APY will be credited at the end of the term of 6 months or less, and quarterly for term of over 6 months. Penalty will be imposed for early withdrawal. All rates and APYs are offered at the bank’s discretion and may change daily. Fees could reduce earnings on the account.
