"Although we are actively lending and have ample liquidity, we are being prudent in our underwriting of new loans. This and increased payoffs from an improving economy have caused a dip in our loan portfolio," said Kenneth D. Brenner, the Company's Chief Executive Officer. "The active maintenance of our net interest margin and ongoing program of expense control are continuing drivers of the Bank's profitability."
