Forward-looking statements represent management’s beliefs, based upon information available at the time the statements are made, with regard to the matters addressed; they are not guarantees of future performance. Forward-looking statements are subject to numerous assumptions, risks and uncertainties that change over time and could cause actual results or financial condition to differ materially from those expressed in or implied by such statements. Factors that could cause or contribute to such differences include, but are not limited to: the level of market volatility, our ability to execute our growth strategy, including the availability of future bank acquisition opportunities, our ability to execute on our revenue and efficiency improvement initiatives, unanticipated losses related to the completion and integration of mergers and acquisitions, refinements to purchase accounting adjustments for acquired businesses and assets and assumed liabilities in these transactions, adjustments of fair values of acquired assets and assumed liabilities and of deferred taxes in acquisitions, actual results deviating from the Company’s current estimates and assumptions of timing and amounts of cash flows, utilization of non-GAAP financial measures, credit risk of our customers, resolution of assets formerly subject to loss share agreements with the FDIC, effects of the on-going correction in residential real estate prices and levels of home sales, our ability to satisfy new capital and liquidity standards such as those imposed by the Dodd-Frank Wall Street Reform and Consumer Protection Act and those adopted by the Basel Committee on Banking Supervision and federal banking regulators, sufficiency of our allowance for loan losses, changes in interest rates, access to funding sources, reliance on the services of executive management, competition for loans, deposits and investment dollars, competition from competitors with greater financial resources than the Company, reputational risk and social factors, compliance with laws and regulations, increases in FDIC insurance assessments, geographic concentration of our markets, economic and business conditions in our markets or nationally, including the impact of volatility of oil and gas prices, rapid changes in the financial services industry, significant litigation, cyber-security risks including dependence on our operational, technological, and organizational systems and infrastructure and those of third party providers of those services, hurricanes and other adverse weather events, and valuation of intangible assets.
