The bank said its net interest income, the difference between the revenue generated from a bank’s assets and the expense associated with its liabilities, increased 15 percent in the second quarter, year over year, to $21.3 million.

The bank said it plans to open branches in East Islip, College Point in Queens and Bay Ridge in Brooklyn in the next year. The bank already has 44 offices on Long Island and in Queens and Manhattan.
