Accordingly, we caution you that any such forward-looking statements are not guarantees of future performance and are subject to risks, assumptions and uncertainties that are difficult to predict. Although we believe that the expectations reflected in these forward-looking statements are reasonable as of the date made, actual results may prove to be materially different from the results expressed or implied by the forward-looking statements. There are or will be important factors that could cause our actual results to differ materially from those indicated in these forward-looking statements, including, but are limited to, the following: business and economic conditions generally and in the financial services industry, nationally and within our local market area; changes in leadership personnel and their ability to execute our strategy; economic, market, operational, liquidity, credit and interest rate risks associated with our business; deterioration of our asset quality; changes in real estate values; increased competition in the financial services industry, nationally, regionally or locally, which may adversely affect pricing and terms; our ability to identify potential candidates for, and consummate, acquisitions of banking franchises on attractive terms, or at all; our ability to achieve organic loan and deposit growth and the composition of that growth; volatility and direction of market interest rates; changes in the regulatory environment, including changes in regulations that affect the fees that we charge or expenses that we incur in connection with our operations; governmental legislation and regulation, including changes in accounting regulation or standards and changes in trade, monetary, tax and fiscal policies and laws; natural disasters, adverse weather and other man-made disasters, acts of terrorism, and other matters beyond our control; and other factors.

Accordingly, you should not place undue reliance on any such forward-looking statements. Any forward-looking statement speaks only as of the date on which it is made, and we do not undertake any obligation to publicly update or review any forward-looking statement, whether as a result of new information, future developments or otherwise. In addition, we cannot assess the impact of each factor on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements.
