“Management’s focus on noninterest income over the past year led to a roughly 7% year to date increase in the category. This is a long-term strategic focus and we continue to implement strategies to engage our customers in ways that create shared value for both the Bank and the customer,” said Benjamin Bochnowski, president and chief executive officer. “Results were largely as planned and stem from the continued execution of the Bank’s strategic plan. The Company’s strong financial performance reflects the Bank’s customer focus as we continue to find opportunities for growth in the local economy.”

“The Bancorp’s six and three month earnings increase has been positively impacted by management’s ability to consistently grow its loan portfolio and core deposit funding. For the current year, loan originations have increased in excess of 10%, compared to last year. In addition, the Bancorp’s earnings have been enhanced by increased noninterest income and well managed operating expenses,” said Robert Lowry, chief financial officer. “The Bancorp’s earnings continue to create capital that will be used to fuel future growth.”
