In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities as of the date of the consolidated balance sheet, and revenue and expenses for the period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the allowance for credit losses, the valuation of derivative instruments, investment securities valuation, evaluation of investment securities for other than temporary impairment and deferred income taxes valuation.</span></div>
