American Savings Bank’s earnings slipped 1.4 percent in the fourth quarter after settling a class-action lawsuit related to overdraft fees on debit card transactions, costs related to its soon-to-be-built headquarters in Chinatown and more money set aside for potential loan losses.

The state’s third-largest bank said Friday that net income fell to $12 million from $12.2 million in the year-earlier quarter. American Savings, though, boosted its loans 6.8 percent and its deposits 5.7 percent.

American Savings is scheduled to be spun off within the next 12 months by parent Hawaiian Electric Industries Inc. into a stand-alone entity if a $4.3 billion merger with Florida-based NextEra Energy Inc. is approved by regulators and shareholders.

For the year, American Savings’s net income dropped 10.5 percent to $51.5 million from $57.5 million.
