Unfunded credit reserves include reserves provided for unfunded lending commitments, unissued standby letters of credit and recourse obligations for loans sold. The allowance for loan losses is established as management’s estimate of probable losses inherent in the Company’s lending activities. The allowance for loan losses is increased by the provision for loan losses and decreased by net charge-offs when management believes the uncollectability of a loan is confirmed. The allowance for loan losses is evaluated on a regular basis by management and is based on management’s periodic review of the collectability of the loans.</font></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The allowance for loan losses on non-PCI loans consists of specific reserves and general reserves. The Company’s non-PCI loans fall into heterogeneous and homogeneous categories. Impaired loans are subject to specific reserves. Loans in the homogeneous category, as well as non-impaired loans in the heterogeneous category, are evaluated as part of the general reserves. General reserves are calculated by utilizing both quantitative and qualitative factors. There are different qualitative risks for the loans in each portfolio segment. The residential and CRE segments’ predominant risk characteristics are the collateral and the geographic locations of the properties collateralizing the loans. The risk is qualitatively assessed based on the total real estate loan concentration in those geographic areas. The C&I segment’s predominant risk characteristics are the global cash flows of the borrowers and guarantors and economic and market conditions. Consumer loans are largely comprised of home equity lines of credit (“HELOCs”) for which the predominant risk characteristic is the real estate collateral securing the loans.</font></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The Company also maintains an allowance for loan losses on purchased credit impaired (“PCI”) loans when there is deterioration in credit quality subsequent to acquisition. Based on the Company’s estimates of cash flows expected to be collected, the Company establishes an allowance for the PCI loans, with a charge to income through the provision for loan losses.  </font></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">When determined uncollectible, it is the Company’s policy to promptly charge off the difference in the outstanding loan balance and the fair value of the collateral or the discounted value of expected cash flows. Recoveries are recorded when payment is received on loans that were previously charged off through the allowance for loan losses. Allocation of a portion of the allowance to one segment of the loan portfolio does not preclude its availability to absorb losses in other segments.</font></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"> </font></div><div style="line-height:120%;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The allowance for unfunded credit reserves is maintained at a level believed by management to be sufficient to absorb estimated probable losses related to unfunded credit facilities. The determination of the adequacy of the allowance is based on periodic evaluations of the unfunded credit facilities, including an assessment of the probability of commitment usage, credit risk factors for loans outstanding to these same customers, and the terms and expiration dates of the unfunded credit facilities. The allowance for loan losses is reported separately on the Consolidated Balance Sheets, whereas the allowance for unfunded credit reserves is reported in accrued expenses and other liabilities. The provision for credit losses is reported in the Consolidated Statements of Income. </font></div></div>
