Actual results could differ from those estimates. Estimates that could change significantly relate to the provision for credit losses and the related allowance, potential impairment of goodwill or other intangible assets, valuation of investment securities and the determination of whether available-for-sale debt securities with fair values less than amortized costs are impaired and require an allowance for credit losses, valuation of other real estate owned, valuation of share based compensation, the assessment that a liability should be recognized with respect to any matters under litigation, the calculation of current and deferred income taxes, and the actuarial projections related to pension expense and the related liability.</span></div>

Derivative loan commitments are recognized at fair value in the Consolidated Statements of Condition in other assets or other liabilities with changes in their fair values recorded as a component of mortgage banking activities in the Consolidated Statements of Income.</span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Mortgage loan commitments are issued to borrowers. Subsequent to commitment date, changes in the fair value of the loan commitment are recognized based on changes in the fair value of the underlying mortgage loan due to interest rate changes, changes in the probability the derivative loan commitment will be exercised, and the passage of time. In estimating fair value, a probability is assigned to a loan commitment based on an expectation that it will be exercised and the loan will be funded.</span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Forward Loan Sale Commitments</span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">Loan sales agreements are evaluated to determine whether they meet the definition of a derivative as facts and circumstances may differ significantly. If agreements qualify, to protect against the price risk inherent in derivative loan commitments, the Company utilizes both “mandatory delivery” and “best efforts” forward loan sale commitments to mitigate the risk of potential decreases in the values of loans that would result from the exercise of the derivative loan commitments. Mandatory delivery contracts are accounted for as derivative instruments. Generally, best efforts contracts also meet the definition of derivative instruments after the loan to the borrower has closed. Accordingly, forward loan sale commitments that economically hedge the closed loan inventory are recognized at fair value in the Consolidated Statements of Condition in other assets or other liabilities with changes in their fair values recorded as a component of mortgage banking activities in the Consolidated Statements of Income. The Company estimates the fair value of its forward loan sales commitments using a methodology similar to that used for derivative loan commitments.</span></div><div style="text-align:justify"><span><br/></span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-style:italic;font-weight:700;line-height:120%">Interest Rate Swap Agreements</span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">The Company enters into interest rate swaps (“swaps”) with commercial loan customers to provide a facility to mitigate the fluctuations in the variable rate on the respective loans. These swaps are matched in exact offsetting terms to swaps that the Company enters into with an outside third party. The swaps are reported at fair value in other assets or other liabilities in the Consolidated Statements of Condition. The Company's swaps qualify as derivatives, but are not designated as hedging instruments, thus any net </span></div><div style="text-align:justify"><span style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:120%">gain or loss resulting from changes in the fair value is recognized in other non-interest income in the Consolidated Statements of Income.
