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>

Refer to Note 5 for more details on the Company’s portfolio segments. </span></div><div><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%">The Company applies two calculation methodologies to estimate the collective quantified component of the allowance: discounted cash flows method and weighted average remaining life method. Allowance estimates on commercial acquisition, development and construction (“AD&C”) and residential construction segments are based on the weighted average remaining life method. Allowance estimates on all other portfolio segments are based on the discounted cash flows method. Segments utilizing the discounted cash flows method are further sub-segmented into risk level pools, determined either by risk rating for commercial loans or Beacon Scores ranges for residential and consumer loans. To better manage risk and reasonably determine the sufficiency of reserves, this segregation allows the Company to monitor the allowance component applicable to higher risk loans separate from the remainder of the portfolio. Collective calculation methodologies utilize the Company’s historical default and loss experience adjusted for future economic forecasts. The reasonable and supportable forecast period represents a two-year economic outlook for the applicable economic variables. Following the end of the reasonable and supportable forecast period expected losses revert back to the historical mean over the next two years on a straight-line basis. Economic variables that have the most significant impact on the allowance include: unemployment rate, house price index and business bankruptcies. Contractual loan level cash flows within the discounted cash flows methodology are adjusted for the Company’s historical prepayment and curtailment rate experience.</span></div><div><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%">The individual reserve assessment is applied to collateral dependent loans where borrowers are experiencing financial difficulty or when the Company determines that a foreclosure is probable. The determination of the fair value of the collateral depends on whether a repayment of the loan is expected to be from the sale or the operation of the collateral. When a repayment is expected from the operation of the collateral, the Company uses the present value of expected cash flows from the operation of the collateral as the fair value. When the repayment of the loan is expected from the sale of the collateral the fair value of the collateral is based on an observable market price or the collateral’s appraised value, less estimated costs to sell. Third-party appraisals used in the individual reserve assessment are conducted at least annually with underlying assumptions that are reviewed by management. Third-party appraisals may be obtained on a more frequent basis if deemed necessary. Internal evaluations of collateral value are conducted quarterly to ensure any further deterioration of the collateral value is recognized on a timely basis. During the individual reserve assessment, management also considers the potential future changes in the value of the collateral over the remainder of the loan’s remaining life. The Company may receive updated appraisals which contradict the preliminary determination of fair value used to establish an individual allowance on a loan. In these instances the individual allowance is adjusted to reflect the Company’s evaluation of the updated appraised fair value. In the event a loss was previously confirmed and the loan was charged down to the estimated fair value based on a previous appraisal, the balance of partially charged-off loans are not subsequently increased, but could be further decreased depending on the direction of the change in fair value. Payments on fully or partially charged-off loans are accounted for under the cost-recovery method. Under this method, all payments received are applied on a cash basis to reduce the entire outstanding principal balance, then to recognize a recovery of all previously charged-off amounts before any interest income may be recognized. Based on the individual reserve assessment, if the Company determines that the fair value of the collateral is less than the amortized cost basis of the loan, an individual allowance will be established measured as the difference between the fair value of the collateral (less costs to sell) and the amortized cost basis of the loan. Once a loss has been confirmed, the loan is charged-down to its estimated fair value.</span></div><div><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%">Large groups of smaller non-accrual homogeneous loans are not individually evaluated for allowance and include residential permanent and construction mortgages and consumer installment loans.

However, the determination of the allowance requires significant judgment, and estimates of expected lifetime losses in the loan portfolio can vary significantly from the amounts actually observed. While management uses available information to recognize expected losses, future additions to the allowance may be necessary based on changes in the loans comprising the portfolio, changes in the current and forecasted economic conditions, changes to the interest rate environment which may directly impact prepayment and curtailment rate assumptions, and changes in the financial condition of borrowers.</span></div>

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 gain or loss resulting from changes in the fair value is recognized in other non-interest income in the Consolidated Statements of Income. Further discussion of the Company's financial derivatives is set forth in Note 18.</span></div>
