Financial Institutions Inc.'s net income doubled in the second quarter of 2010, compared with the same period last year.

The parent of Five Star Bank said this week that its net income totaled $5.2 million for the quarter ending June 30, up 100 percent from $2.6 million in net income reported for the second quarter of 2009. Shares rose to 39 cents, up from 16 cents per share a year ago.

Net interest income increased to $19.7 million for the quarter, compared with $17.7 million for the same quarter last year. That was due to "decreased rates paid on deposits and growth in loans and leases," the bank said. Noninterest income also rose, from $4.5 million a year ago to $5 million during the second quarter.

Nonperforming assets totaled $12.5 million, down from $13.7 million a year ago. The bank said its increase in nonperforming loans during the last quarter stems from participation in a single commercial loan. Loan-loss provisions remained steady at $2.1 million, the same number set aside during the second quarter of 2009.

Five Star is the eighth-largest deposit-taker in Western New York, according to the Federal Deposit Insurance Corp. It is headquartered in Warsaw and operates 20 branches in Western New York.
