How does overdraft protection from my savings account to my checking account work?

When you specify overdraft protection from savings account, we will automatically transfer funds from the available balance in your savings to the checking account in the event your checking account balance is not sufficient to cover an item presented for payment.

Transfers from the savings account are made in the amount that is needed to cover the insufficient transaction amount and are subject to Regulation D, which limits the number of unsigned transfers to six (6) per month. There is a fee for the transfer.
