A tentative $9 million settlement with Bank of Hawaii requires the bank to pay each of its customers who had more than one overdraft fee in a day over the last five years.

Bank of Hawaii, the state's second-largest bank, reached the class-action lawsuit settlement in response to claims that the bank improperly charged overdraft fees on debit card transactions, the Honolulu Star-Advertiser reported Tuesday.

The lawsuit accused the bank of systematically re-ordering debit card transactions from highest dollar amount to lowest dollar amount, a practice that allowed the bank to deplete customers' available funds as quickly as possible while maximizing the number of overdraft fees.

The $9 million will be put in a settlement fund used to refund customers and pay attorneys' fees, administrative and other costs in exchange for a complete release of all claims against the company, the bank said. It's unclear how many Bank of Hawaii customers are eligible for refunds.

Similar lawsuits against American Savings Bank and Central Pacific Bank, the state's third- and fourth-largest banks, also are pending.
