For each ATM cash withdrawal, this International Transaction Fee is 3% of the U.S. dollar amount, and for each purchase, this International Transaction Fee is 3% of the U.S. dollar amount

When you use a foreign ATM, you could be charged a variety of fees, likw
Non-bank ATM usage fees,
ATM operator access fees, and
International transaction fees for conversion to U.S. dollars
To limit such fees is to use your Bank of America ATM or debit card at one of its international partner ATMs.
This enables you to avoid the Non-Bank of America ATM $5 usage fee for each withdrawal, transfer or balance inquiry as well as the ATM operator access fee.
