NOTES TO UNAUDITED INTERIM CONSOLIDATED FINANCIAL STATEMENTS

September 30, 2011

Note 1.                      Description of Business

NBT Bancorp Inc. (the “Registrant”) is a registered financial holding company incorporated in the State of Delaware in 1986, with its principal headquarters located in Norwich, New York. The Registrant is the parent holding company of NBT Bank, N.A. (the “Bank”), NBT Financial Services, Inc. (“NBT Financial”), NBT Holdings, Inc. (“NBT Holdings”), CNBF Capital Trust I, NBT Statutory Trust I and NBT Statutory Trust II (the “Trusts”).  Through the Bank, the Company is focused on community banking operations.  Through NBT Financial, the Company operates EPIC Advisors, Inc. (“EPIC”), a retirement plan administrator.  Through NBT Holdings, the Company operates Mang Insurance Agency, LLC (“Mang”), a full-service insurance agency.  The Trusts were organized to raise additional regulatory capital and to provide funding for certain acquisitions. The Registrant’s primary business consists of providing commercial banking and financial services to customers in its market area. The principal assets of the Registrant are all of the outstanding shares of common stock of its direct subsidiaries, and its principal sources of revenue are the management fees and dividends it receives from the Bank, NBT Financial, and NBT Holdings.

The Bank is a full service commercial bank formed in 1856, which provides a broad range of financial products to individuals, corporations and municipalities throughout the upstate New York, northeastern Pennsylvania, northwestern Vermont, and western Massachusetts market areas.

Note 2.                      Basis of Presentation

The accompanying unaudited interim consolidated financial statements include the accounts of the Registrant and its wholly owned subsidiaries, the Bank, NBT Financial and NBT Holdings.  Collectively, the Registrant and its subsidiaries are referred to herein as “the Company.”  All intercompany transactions have been eliminated in consolidation. Amounts in the prior period financial statements are reclassified whenever necessary to conform to current period presentation.

Note 3.                      Use of Estimates

Preparing financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period, as well as the disclosures provided. Actual results could differ from those estimates. Estimates associated with the allowance for loan and lease losses, other real estate owned (“OREO”), income taxes, pension expense, fair values of financial instruments and status of contingencies are particularly susceptible to material change in the near term.

The allowance for loan and lease losses is the amount which, in the opinion of management, is necessary to absorb probable losses inherent in the loan and lease portfolio. The allowance is determined based upon numerous considerations, including local and national economic conditions, the growth and composition of the loan portfolio with respect to the mix between the various types of loans and their related risk characteristics, a review of the value of collateral supporting the loans, comprehensive reviews of the loan portfolio by the independent loan review staff and management, as well as consideration of volume and trends of delinquencies, nonperforming loans, and loan charge-offs.  As a result of the review of these factors and historical and current indicators, required additions or reductions to the allowance for loan and lease losses are made periodically by charges or credits to the provision for loan and lease losses.

8

The allowance for loan and lease losses related to impaired loans is based on discounted cash flows using the loan’s initial effective interest rate or the fair value of the collateral for certain loans where repayment of the loan is expected to be provided solely by the underlying collateral (collateral dependent loans). The Company’s impaired loans are generally collateral dependent loans. The Company considers the estimated cost to sell, on a discounted basis, when determining the fair value of collateral in the measurement of impairment if those costs are expected to reduce the cash flows available to repay or otherwise satisfy the loans.

Management believes that the allowance for loan and lease losses is adequate. While management uses available information to recognize loan and lease losses, future additions or reductions to the allowance for loan and lease losses may be necessary based on changes in economic conditions or changes in the values of properties securing loans in the process of foreclosure. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the Company’s allowance for loan and lease losses. Such agencies may require the Company to recognize additions to the allowance for loan and lease losses based on their judgments about information available to them at the time of their examination which may not be currently available to management.  In determining that we will be unable to collect all principal and interest payments due in accordance with the contractual terms of the loan agreements, we consider factors such as payment history and changes in the financial condition of individual borrowers, local economic conditions, historical loss experience and the conditions of the various markets in which the collateral may be liquidated.

OREO consists of properties acquired through foreclosure or by acceptance of a deed in lieu of foreclosure. These assets are recorded at the lower of fair value of the asset acquired less estimated costs to sell or “cost” (cost is defined as the fair value less costs to sell at initial foreclosure). At the time of foreclosure, or when foreclosure occurs in-substance, the excess, if any, of the loan over the fair value of the assets received, less estimated selling costs, is charged to the allowance for loan and lease losses and any subsequent valuation write-downs are charged to other expense. Operating costs associated with the properties are charged to expense as incurred. Gains on the sale of OREO are included in income when title has passed and the sale has met the minimum down payment requirements prescribed by U.S. GAAP.

Income taxes are accounted for under the asset and liability method. The Company files consolidated tax returns on the accrual basis. Deferred income taxes are recognized for the future tax consequences and benefits attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Realization of deferred tax assets is dependent upon the generation of future taxable income or the existence of sufficient taxable income within the available carryback period. A valuation allowance is provided when it is more likely than not that some portion of the deferred tax asset will not be realized. Based on available carrybacks and expected future income, gross deferred tax assets will ultimately be realized and a valuation allowance was not deemed necessary at September 30, 2011 or December 31, 2010. The effect of a change in tax rates on deferred taxes is recognized in income in the period that includes the enactment date.  Uncertain tax positions are recognized only when it is more likely than not (likelihood of greater than 50%), based on technical merits, that the position would be sustained upon examination by taxing authorities.  Tax positions that meet the more than likely than not threshold are measured using a probability-weighted approach as the largest amount of tax benefit that is greater than 50% likely of being realized upon settlement.

Management is required to make various assumptions in valuing its pension assets and liabilities. These assumptions include the expected long-term rate of return on plan assets, the discount rate, and the rate of increase in future compensation levels. Changes to these assumptions could impact earnings in future periods. The Company takes into account the plan asset mix, funding obligations, and expert opinions in determining the various assumptions used to compute pension expense. The Company also considers relevant indices and market interest rates in selecting an appropriate discount rate. A cash flow analysis for expected benefit payments from the plan is performed each year to assist in selecting the discount rate.  In addition, the Company reviews expected inflationary and merit increases to compensation in determining the expected rate of increase in future compensation levels.

9

Management is required to make various assumptions in determining the fair values of financial instruments.  Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

Management is required to make various assumptions in determining the credit risk involved in issuing contingent obligations such as standby letters of credit, commercial letters of credit, and other lines of credit.  Since commitments to extend credit and unused lines of credit may expire without being fully drawn upon, this amount does not necessarily represent future cash commitments.  Based on historical experience and economic factors, the Company makes estimates of future cash commitments from these contingent obligations to determine their fair value and establish an allowance if necessary.

Note 4.                      Commitments and Contingencies

The Company is a party to financial instruments in the normal course of business to meet the financing needs of its customers and to reduce its own exposure to fluctuating interest rates. These financial instruments include commitments to extend credit, unused lines of credit, and standby letters of credit. Exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to make loans and standby letters of credit is represented by the contractual amount of those instruments. The Company uses the same credit origination guidelines, portfolio maintenance and management procedures as other credit and off-balance sheet products.  Commitments to extend credit and unused lines of credit totaled $749.2 million at September 30, 2011 and $643.6 million at December 31, 2010.  Since commitments to extend credit and unused lines of credit may expire without being fully drawn upon, this amount does not necessarily represent future cash commitments. Collateral obtained upon exercise of the commitment is determined using management’s credit evaluation of the borrower and may include accounts receivable, inventory, property, land and other items.

The Company guarantees the obligations or performance of customers by issuing standby letters of credit to third parties. These standby letters of credit are frequently issued in support of third party debt, such as corporate debt issuances, industrial revenue bonds and municipal securities. The credit risk involved in issuing standby letters of credit is essentially the same as the credit risk involved in extending loan facilities to customers, and they are subject to the same credit origination guidelines, portfolio maintenance and management procedures as other credit and off-balance sheet products. Typically, these instruments have terms of five years or less and expire unused; therefore, the total amounts do not necessarily represent future cash commitments. Standby letters of credit totaled $26.0 million at September 30, 2011 and $26.2 million at December 31, 2010. As of September 30, 2011, the fair value of standby letters of credit was not significant to the Company’s consolidated financial statements.

The Company has also entered into commercial letter of credit agreements on behalf of its customers.  Under these agreements, the Company, on the request of its customer, opens the letter of credit and makes a commitment to honor draws made under the agreement, whereby the beneficiary is normally the provider of goods and/or services and the Company essentially replaces the customer as the payee.  The credit risk involved in issuing commercial letters of credit is essentially the same as the credit risk involved in extending loan facilities to customers, and they are subject to the same credit origination guidelines, portfolio maintenance and management procedures as other credit and off-balance sheet products.  

10

Typically, these agreements vary in terms and the total amounts do not necessarily represent future cash commitments.  Commercial letters of credit totaled $15.7 million at September 30, 2011 and $16.3 million at December 31, 2010.  As of September 30, 2011, the fair value of commercial letters of credit was not significant to the Company’s consolidated financial statements.

Note  5.                     Allowance for Loan and Lease Losses and Credit Quality of Loans and Leases

Allowance for Loan and Lease Losses

The allowance for loan and lease losses is maintained at a level estimated by management to provide adequately for risk of probable losses inherent in the current loan and lease portfolio. The adequacy of the allowance for loan and lease losses is continuously monitored.  It is assessed for adequacy using a methodology designed to ensure the level of the allowance reasonably reflects the loan and lease portfolio’s risk profile. It is evaluated to ensure that it is sufficient to absorb all reasonably estimable credit losses inherent in the current loan and lease portfolio.

To develop and document a systematic methodology for determining the allowance for loan and lease losses, the Company has divided the loan portfolio into three portfolio segments, each with different risk characteristics and methodologies for assessing risk.  Each portfolio segment is broken down into class segments where appropriate.  Class segments contain unique measurement attributes, risk characteristics and methods for monitoring and assessing risk that are necessary to develop the allowance for loan and lease losses.  Unique characteristics such as borrower type, loan type, collateral type, and risk characteristics define each class segment.  The following table illustrates the portfolio and class segments for the Company’s loan portfolio:

Portfolio	Class
Commercial Loans	Commercial
	Commercial Real Estate
	Agricultural
	Agricultural Real Estate
	Business Banking
Consumer Loans	Indirect
	Home Equity
	Direct
Residential Real Estate Mortgages

Commercial – The Company offers a variety of loan options to meet the specific needs of our commercial customers including term loans, time notes and lines of credit.  Such loans are made available to businesses for working capital such as inventory and receivables, business expansion and equipment purchases. Generally, a collateral lien is placed on equipment or other assets owned by the borrower.  These loans carry a higher risk than commercial real estate loans due to the nature of the underlying collateral, which can be business assets such as equipment and accounts receivable and is generally less liquid than real estate. To reduce the risk, management also attempts to secure real estate as collateral and obtain personal guarantees of the borrowers.

Commercial Real Estate – The Company offers commercial real estate loans to finance real estate purchases, refinancings, expansions and improvements to commercial properties.  Commercial real estate loans are made to finance the purchases of real property which generally consists of real estate with completed structures. These commercial real estate loans are secured by first liens on the real estate, which may include apartments, commercial structures, housing businesses, healthcare facilities, and other non owner-occupied facilities.  These loans are typically less risky than commercial loans, since they are secured by real estate and buildings. The Company’s underwriting analysis includes credit verification, independent appraisals, a review of the borrower's financial condition, and a detailed analysis of the borrower’s underlying cash flows. These loans are typically originated in amounts of no more than 80% of the appraised value of the property.

11

Agricultural – The Company offers a variety of agricultural loans to meet the needs of our agricultural customers including term loans, time notes, and lines of credit.  These loans are made to purchase livestock, purchase and modernize equipment, and finance seasonal crop expenses.  Generally, a collateral lien is placed on the livestock, equipment, produce inventories, and/or receivables owned by the borrower.  These loans may carry a higher risk than commercial and agricultural real estate loans due to the industry price volatility, and in some cases, the perishable nature of the underlying collateral.  To reduce these risks, management may attempt to secure these loans with additional real estate collateral, obtain personal guarantees of the borrowers, or obtain government loan guarantees to provide further support.

Agricultural Real Estate – The Company offers real estate loans to our agricultural customers to finance farm related real estate purchases, refinancings, expansions, and improvements to agricultural properties such as barns, production facilities, and land.  The agricultural real estate loans are secured by first liens on the farm real estate.  Because they are secured by land and buildings, these loans may be less risky than agricultural loans.  The Company's underwriting analysis includes credit verification, independent appraisals, a review of the borrower's financial condition, and a detailed analysis of the borrower’s underlying cash flows.  These loans are typically originated in amounts of no more than 75% of the appraised value of the property.  Government loan guarantees may be obtained to provide further support.

Business Banking - The Company offers a variety of loan options to meet the specific needs of our small business customers including term loans, small business mortgages and lines of credit.  Such loans are generally less than $350 thousand and are made available to businesses for working capital such as inventory and receivables, business expansion, equipment purchases, and agricultural needs.  Generally, a collateral lien is placed on equipment or other assets owned by the borrower such as inventory and/or receivables.  These loans carry a higher risk than commercial loans due to the smaller size of the borrower and lower levels of capital.  To reduce the risk, the Company obtains personal guarantees of the owners for a majority of the loans.

Indirect – The Company maintains relationships with many dealers primarily in the communities that we serve.  Through these relationships, the company finances the purchases of automobiles and recreational vehicles (such as campers, boats, etc.) indirectly through dealer relationships.  Approximately 70% of the indirect relationships represent automobile financing.  Most of these loans carry a fixed rate of interest with principal repayment terms typically ranging from three to six years, based upon the nature of the collateral and the size of the loan. The majority of indirect consumer loans are underwritten on a secured basis using the underlying collateral being financed.

Home Equity –The Company offers fixed home equity loans as well as home equity lines of credit to consumers to finance home improvements, debt consolidation, education and other uses.  Consumers are able to borrow up to 85% of the equity in their homes.  The Company originates home equity lines of credit and second mortgage loans (loans secured by a second [junior] lien position on one-to-four-family residential real estate).  These loans carry a higher risk than first mortgage residential loans as they are in a second position with respect to collateral.  Risk is reduced through underwriting criteria, which include credit verification, appraisals, a review of the borrower's financial condition, and personal cash flows.  A security interest, with title insurance when necessary, is taken in the underlying real estate.

12

Direct – The Company offers a variety of consumer installment loans to finance vehicle purchases, mobile home purchases and personal expenditures.  Most of these loans carry a fixed rate of interest with principal repayment terms typically ranging from one to ten years, based upon the nature of the collateral and the size of the loan. The majority of consumer loans are underwritten on a secured basis using the underlying collateral being financed or a customer's deposit account. In addition to installment loans, the Company also offers personal lines of credit and overdraft protection.  A minimal amount of loans are unsecured, which carry a higher risk of loss.

Residential Real Estate – Residential real estate loans consist primarily of loans secured by first or second deeds of trust on primary residences.  We originate adjustable-rate and fixed-rate, one-to-four-family residential real estate loans for the construction, purchase or refinancing of a mortgage.  These loans are collateralized by owner-occupied properties located in the Company’s market area. When market conditions are favorable, for longer term, fixed-rate residential mortgages without escrow, the Company retains the servicing, but sells the right to receive principal and interest to Freddie Mac.   This practice allows the Company to manage interest rate risk, liquidity risk, and credit risk.  Loans on one-to-four-family residential real estate are generally originated in amounts of no more than 85% of the purchase price or appraised value (whichever is lower), or have private mortgage insurance.  Mortgage title insurance and hazard insurance are normally required. Construction loans have a unique risk, because they are secured by an incomplete dwelling. This risk is reduced through periodic site inspections, including one at each loan draw period.

Allowance for Loan and Lease Loss Calculation

Management considers the accounting policy related to the allowance for loan and lease losses to be a critical accounting policy given the inherent uncertainty in evaluating the levels of the allowance required to cover credit losses in the portfolio and the material effect that such judgments can have on the consolidated results of operations.

For purposes of evaluating the adequacy of the allowance, the Company considers a number of significant factors that affect the collectibility of the portfolio.  For individually analyzed loans, these include estimates of loss exposure, which reflect the facts and circumstances that affect the likelihood of repayment of such loans as of the evaluation date. For homogeneous pools of loans and leases, estimates of the Company’s exposure to credit loss reflect a current assessment of a number of factors, which could affect collectibility.  These factors include:  past loss experience;  size, trend, composition, and nature of loans;  changes in lending policies and procedures, including underwriting standards and collection,  charge-offs  and  recoveries; trends experienced in nonperforming and delinquent loans; current economic conditions in the Company’s market;  portfolio concentrations that may affect loss experienced across one or more components of the portfolio; the effect of external factors such as competition, legal and regulatory requirements; and the experience, ability, and depth of lending management and staff. In addition, various regulatory agencies, as an integral component of their examination process, periodically review the Company’s allowance for loan and lease losses.  Such agencies may require the Company to make loan grade changes as well as recognize additions to the allowance based on their examinations.

After a thorough consideration of the factors discussed above, any required additions or reductions to the allowance for loan and lease losses are made periodically by charges or credits to the provision for loan and lease losses. These charges or credits are necessary to maintain the allowance at a level which management believes is reasonably reflective of overall inherent risk of probable loss in the portfolio. While management uses available information to recognize losses on loans and leases, additions and reductions of the allowance may fluctuate from one reporting period to another.  These fluctuations are reflective of changes in risk associated with portfolio content and/or changes in management’s assessment of any or all of the determining factors discussed above.  The following table illustrates the changes in the allowance for loan and lease losses by portfolio segment for the three and nine months ended September 30, 2011 and September 30, 2010:

Credit Quality of Loans and Leases

Loans and leases are placed on nonaccrual status when timely collection of principal and interest in accordance with contractual terms is doubtful. Loans and leases are transferred to nonaccrual status generally when principal or interest payments become ninety days delinquent, unless the loan is well secured and in the process of collection, or sooner when management concludes or circumstances indicate that borrowers may be unable to meet contractual principal or interest payments.  When a loan or lease is transferred to a nonaccrual status, all interest previously accrued in the current period but not collected is reversed against interest income in that period. Interest accrued in a prior period and not collected is charged-off against the allowance for loan and lease losses.  The Company’s nonaccrual policies are the same for all classes of financing receivable.

15

If ultimate repayment of a nonaccrual loan is expected, any payments received are applied in accordance with contractual terms. If ultimate repayment of principal is not expected, any payment received on a nonaccrual loan is applied to principal until ultimate repayment becomes expected.  Nonaccrual loans are returned to accrual status when they become current as to principal and interest and demonstrate a period of performance under the contractual terms and, in the opinion of management, are fully collectible as to principal and interest.  When in the opinion of management the collection of principal appears unlikely, the loan balance is charged-off in total or in part.  For loans in all portfolios, the principal amount is charged off in full or in part as soon as management determines, based on available facts, that the collection of principal in full is improbable.  For commercial loans, management considers specific facts and circumstances relative to individual credits in making such a determination.  For consumer and residential loan classes, management uses specific guidance and thresholds from the Federal Financial Institutions Examination Council’s Uniform Retail Credit Classification and Account Management Policy.

There were no material commitments to extend further credit to borrowers with nonperforming loans. Within nonaccrual loans, there were approximately $4.6 million and $1.0 million of troubled debt restructured (“TDR”) loans at September 30, 2011 and December 31, 2010, respectively.

Impaired loans, which primarily consist of nonaccruing commercial, commercial real estate, agricultural, agricultural real estate and business banking loans, as well as certain consumer loans that have been modified in a TDR were $23.7 million at September 30, 2011 and $25.4 million at December 31, 2010.

The methodology used to establish the allowance for loan and lease losses on impaired loans incorporates specific allocations on loans analyzed individually.  Classified loans with outstanding balances of $500 thousand or more are evaluated for impairment through the Company’s quarterly status review process.  In determining that we will be unable to collect all principal and interest payments due in accordance with the contractual terms of the loan agreements, we consider factors such as payment history and changes in the financial condition of individual borrowers, local economic conditions, historical loss experience and the conditions of the various markets in which the collateral may be liquidated.  For loans that are evaluated for impairment, impairment is measured by one of three methods: 1) the fair value of collateral less cost to sell, 2) present value of expected future cash flows or 3) the loan’s observable market price.  These impaired loans are reviewed on a quarterly basis for changes in the measurement of impairment.  For impaired loans measured using the present value of expected cash flow method, any change to the previously recognized impairment loss is recognized as a change to the allowance account and recorded in the consolidated statement of income as a component of the provision for credit losses.  At September 30, 2011, $0.5 million of the total impaired loans had a specific reserve allocation of $0.2 million compared to $5.7 million of impaired loans at December 31, 2010 which had a specific reserve allocation of $2.2 million.

There has been significant disruption and volatility in the financial and capital markets since the second half of 2008.  Turmoil in the mortgage industry adversely impacted both domestic and global economies and led to a significant credit and liquidity crisis in many domestic markets.  These conditions were attributable to a variety of factors, in particular the fallout associated with subprime mortgage loans (a type of lending we have never actively pursued).  The disruption was exacerbated by the decline of the real estate and housing market.  However, in the markets in which the Company does business, the disruption has been somewhat delayed and less significant than in the national market.  For example, our real estate market has not suffered the extreme declines seen nationally and our unemployment rate, while notably higher than in prior periods, is still below the national average.

While we continue to adhere to prudent underwriting standards, as a lender we may be adversely impacted by general economic weaknesses and, in particular, a sharp downturn in the housing market nationally.  Decreases in real estate values could adversely affect the value of property used as collateral for our loans.  Adverse changes in the economy may have a negative effect on the ability of our borrowers to make timely loan payments, which would have an adverse impact on our earnings.  An adverse impact on loan delinquencies would decrease our net interest income and adversely impact our loan loss experience, causing increases in our provision and allowance for loan and lease losses.

21

The Company has developed an internal loan grading system to evaluate and quantify the Bank’s loan portfolio with respect to quality and risk.  The system focuses on, among other things, financial strength of borrowers, experience and depth of borrower’s management, primary and secondary sources of repayment, payment history, nature of the business, and outlook on particular industries.  The internal grading system enables the Company to monitor the quality of the entire loan portfolio on a consistent basis and provide management with an early warning system, enabling recognition and response to problem loans and potential problem loans.

Commercial Grading System

For commercial and agricultural loans, the Company uses a grading system that relies on quantifiable and measurable characteristics when available.  This would include comparison of financial strength to available industry averages, comparison of transaction factors (loan terms and conditions) to loan policy, and comparison of credit history to stated repayment terms and industry averages. Some grading factors are necessarily more subjective such as economic and industry factors, regulatory environment, and management.  Classified commercial loans consist of loans graded substandard and below.  All classified loans with outstanding balances of $500 thousand or more are evaluated individually for impairment through the quarterly review process.  The grading system for commercial and agricultural loans is as follows:

· Doubtful

A doubtful loan has a high probability of total or substantial loss, but because of specific pending events that may strengthen the asset, its classification as a loss is deferred. Doubtful borrowers are usually in default, lack adequate liquidity or capital, and lack the resources necessary to remain an operating entity. Pending events can include mergers, acquisitions, liquidations, capital injections, the perfection of liens on additional collateral, the valuation of collateral, and refinancing. Generally, pending events should be resolved within a relatively short period and the ratings will be adjusted based on the new information. Nonaccrual treatment is required for doubtful assets because of the high probability of loss.

· Substandard

Substandard loans have a high probability of payment default, or they have other well-defined weaknesses. They require more intensive supervision by bank management. Substandard loans are generally characterized by current or expected unprofitable operations, inadequate debt service coverage, inadequate liquidity, or marginal capitalization. Repayment may depend on collateral or other credit risk mitigants. For some Substandard loans, the likelihood of full collection of interest and principal may be in doubt and should be placed on nonaccrual. Although Substandard assets in the aggregate will have a distinct potential for loss, an individual asset’s loss potential does not have to be distinct for the asset to be rated Substandard.

· Special Mention

Special Mention loans have potential weaknesses that may, if not checked or corrected, weaken the asset or inadequately protect the Company’s position at some future date. These loans pose elevated risk, but their weakness does not yet justify a Substandard classification. Borrowers may be experiencing adverse operating trends (declining revenues or margins) or may be struggling with an ill-proportioned balance sheet (e.g., increasing inventory without an increase in sales, high leverage, tight liquidity). Adverse economic or market conditions, such as interest rate increases or the entry of a new competitor, may also support a Special Mention rating. Although a Special Mention loan has a higher probability of default than a pass asset, its default is not imminent.

22

· Pass

Loans graded as Pass encompass all loans not graded as Doubtful, Substandard, or Special Mention.  Pass loans are in compliance with loan covenants, and payments are generally made as agreed.  Pass loans range from superior quality to fair quality.

Business Banking Grading System

Business Banking loans are graded as either Classified or Non-classified:

· Classified

Classified loans are inadequately protected by the current worth and paying capacity of the obligor or, if applicable, the collateral pledged.   These loans have a well-defined weakness, or weaknesses, that jeopardize the liquidation of the debt, or in some cases make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected.   Classified loans have a high probability of payment default, or a high probability of total or substantial loss.  These loans require more intensive supervision by management and are generally characterized by current or expected unprofitable operations, inadequate debt service coverage, inadequate liquidity, or marginal capitalization.  Repayment may depend on collateral or other credit risk mitigants.  When the likelihood of full collection of interest and principal may be in doubt; classified loans are considered to have a nonaccrual status.   In some cases, Classified loans are considered uncollectible and of such little value that their continuance as assets is not warranted.

· Non-classified

Loans graded as Non-classified encompass all loans not graded as Classified.  Non-classified loans are in compliance with loan covenants, and payments are generally made as agreed.

Consumer and Residential Mortgage Grading System

Consumer and Residential Mortgage loans are graded as either Performing or Nonperforming.   Nonperforming loans are loans that are 1) over 90 days past due and interest is still accruing, 2) on nonaccrual status or 3) restructured.  All loans not meeting any of these three criteria are considered Performing.

Modifications

The Company’s loan portfolio includes certain loans that have been modified in a TDR, where economic concessions have been granted to borrowers who have experienced or are expected to experience financial difficulties.  These concessions typically result from the Company’s loss mitigation activities and could include reductions in the interest rate, payment extensions, forgiveness of principal, forbearance or other actions.  Certain TDRs are classified as nonperforming at the time of restructure and may only be returned to performing status after considering the borrower’s sustained repayment performance for a reasonable period, generally six months.

When the Company modifies a loan, management evaluates any possible impairment based on the present value of the expected future cash flows, discounted at the contractual interest rate of the original loan agreement, except when the sole (remaining) source of repayment for the loan is the operation or liquidation of the collateral.  In these cases, management uses the current fair value of the collateral, less selling costs, instead of discounted cash flows.  If management determines that the value of the modified loan is less than the recorded investment in the loan (net of previous charge-offs, deferred loan fees or costs and unamortized premium or discount), impairment is recognized by segment or class of loan as applicable, through an allowance estimate or a charge-off to the allowance.  Segment and class status is determined by the loan’s classification at origination.

25

Modifications made during the three month period ending September 30, 2011 consisted of three commercial loans totaling $0.7 million.   Modifications made during the nine month period ending September 30, 2011 consisted of twenty-five home equity modifications totaling $2.4 million and four residential real estate mortgages totaling $0.8 million, in addition to the three aforementioned commercial loan modifications.  For all such modifications, the pre and post outstanding recorded investment amount remained unchanged.  During the three month period ending September 30, 2011 there were no subsequent defaults on previously modified loans.  During the nine months ended September 30, 2011, there were six home equity loans classified as TDRs totaling $0.6 million and two residential real estate loans classified as TDRs totaling $0.4 million that subsequently defaulted on their renegotiated terms.

As a result of adopting the amendments in Accounting Standards Update (“ASU”) No. 2011-02, “A Creditor’s Determination of Whether a Restructuring Is a Troubled Debt Restructuring (Topic 310)”, the Company reassessed all restructurings that occurred on or after the beginning of the current fiscal year (January 1, 2011) for identification as TDRs.  The Company identified as TDRs certain receivables for which the allowance for credit losses had previously been measured under a general allowance for credit losses methodology.  Upon identifying those receivables as TDRs, the Company identified them as impaired under the guidance in Section 310-10-35 and evaluated TDRs for impairment in accordance with the Company’s methodology used to establish the allowance for loan and lease losses on impaired loans. The amendments in ASU No. 2011-02 require prospective application of the impairment measurement guidance in Section 310-10-35 for those receivables newly identified as impaired.  Adoption of this amendment had no material impact on the Company’s measured of impairment on these loans.

Note 6.                      Earnings Per Share

Basic earnings per share excludes dilution and is computed by dividing income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity (such as the Company’s dilutive stock options and restricted stock units).

The following is a reconciliation of basic and diluted earnings per share for the periods presented in the consolidated statements of income.

There were 1,651,159 stock options for the quarter ended September 30, 2011 and 1,476,461stock options for the quarter ended September 30, 2010 that were not considered in the calculation of diluted earnings per share since the stock options’ exercise price was greater than the average market price during these periods.

There were 1,239,021 stock options for the nine months ended September 30, 2011 and 1,433,276stock options for the nine months ended September 30, 2010 that were not considered in the calculation of diluted earnings per share since the stock options’ exercise price was greater than the average market price during these periods.

Note 7.                      Defined Benefit Postretirement Plans

The Company has a qualified, noncontributory, defined benefit pension plan covering substantially all of its employees at September 30, 2011.  Benefits paid from the plan are based on age, years of service, compensation and social security benefits, and are determined in accordance with defined formulas. The Company’s policy is to fund the pension plan in accordance with Employee Retirement Income Security Act (“ERISA”) standards. Assets of the plan are invested in publicly traded stocks and bonds and mutual funds. Prior to January 1, 2000, the Company’s plan was a traditional defined benefit plan based on final average compensation.  On January 1, 2000, the plan was converted to a cash balance plan with grandfathering provisions for existing participants.

In addition to the pension plan, the Company also provides supplemental employee retirement plans to certain current and former executives.  These supplemental employee retirement plans and the defined benefit pension plan are collectively referred to herein as “Pension Benefits.”

Also, the Company provides certain health care benefits for retired employees.  Benefits are accrued over the employees’ active service period. Only employees that were employed by the Company on or before January 1, 2000 are eligible to receive postretirement health care benefits.  The plan is contributory for participating retirees, requiring participants to absorb certain deductibles and coinsurance amounts with contributions adjusted annually to reflect cost sharing provisions and benefit limitations called for in the plan.  Eligibility is contingent upon the direct transition from active employment status to retirement without any break in employment from the Company.  Employees also must be participants in the Company’s medical plan prior to their retirement.  The Company funds the cost of postretirement health care as benefits are paid. The Company elected to recognize the transition obligation on a delayed basis over twenty years.  These postretirement benefits are referred to herein as “Other Benefits.”

The components of expense for Pension Benefits and Other Benefits are set forth below (in thousands):

	Pension Benefits						Other Benefits
	Three months ended September 30,						Three months ended September 30,
Components of net periodic benefit cost:	2011			2010			2011		2010
Service cost	$	668		$	749		$	5	$	2
Interest cost		874			966			57		65
Expected return on plan assets		(1,914	)		(1,568	)		-		-
Net amortization		408			273			9		15
Total cost (benefit)	$	36		$	420		$	71	$	82

	Pension Benefits						Other Benefits
	Nine months ended September 30,						Nine months ended September 30,
Components of net periodic benefit cost:		2011			2010			2011		2010
Service cost	$	2,003		$	1,674		$	15	$	12
Interest cost		2,621			2,710			171		171
Expected return on plan assets		(5,742	)		(5,124	)		-		-
Net amortization		1,221			1,076			27		(1	)
Total cost (benefit)	$	103		$	336		$	213	$	182

The Company is not required to make contributions to the plans in 2011, and did not do so during the nine months ended September 30, 2011.  The Company recorded approximately $0.3 million and $0.7 million, net of tax, as amortization of pension amounts previously recognized in Accumulated Other Comprehensive Income during the three and nine months ended September 30, 2011, respectively.

28

Market conditions can result in an unusually high degree of volatility and increase the risks and short term liquidity associated with certain investments held by the Company’s defined benefit pension plan (“the Plan”) which could impact the value of these investments.

Note 8.                      Trust Preferred Debentures

CNBF Capital Trust I is a Delaware statutory business trust formed in 1999, for the purpose of issuing $18 million in trust preferred securities and lending the proceeds to the Company. NBT Statutory Trust I is a Delaware statutory business trust formed in 2005, for the purpose of issuing $5 million in trust preferred securities and lending the proceeds to the Company.  NBT Statutory Trust II is a Delaware statutory business trust formed in 2006, for the purpose of issuing $50 million in trust preferred securities and lending the proceeds to the Company to provide funding for the acquisition of CNB Bancorp, Inc. These three statutory business trusts are collectively referred herein to as “the Trusts.”  The Company guarantees, on a limited basis, payments of distributions on the trust preferred securities and payments on redemption of the trust preferred securities.  The Trusts are variable interest entities (“VIEs”) for which the Company is not the primary beneficiary, as defined by U.S. GAAP.  In accordance with U.S. GAAP, the accounts of the Trusts are not included in the Company’s consolidated financial statements.  On January 1, 2010, the Company adopted ASU 2009-17, Consolidations: Improvements to Financial Reporting by Enterprises Involved with Variable Interest Entities (“Topic 810”), which had no impact on the Company’s financial statements.

As of September 30, 2011, the Trusts had the following issues of trust preferred debentures, all held by the Trusts, outstanding (dollars in thousands):

Description	Issuance Date	Trust Preferred Securities Outstanding		Interest Rate	Trust Preferred Debt Owed To  Trust		Final Maturity date
CNBF Capital Trust I	June 1999		18,000	3-month LIBOR plus 2.75%	$	18,720	August 2029
NBT Statutory Trust I	November 2005		5,000	3-month LIBOR plus 1.40%		5,155	December 2035
NBT Statutory Trust II	February 2006		50,000	3-month LIBOR plus 1.40%		51,547	March 2036

The Company owns all of the common stock of the Trusts, which have issued trust preferred securities in conjunction with the Company issuing trust preferred debentures to the Trusts. The terms of the trust preferred debentures are substantially the same as the terms of the trust preferred securities.

Note 9.                      Fair Value Measurements and Fair Value of Financial Instruments

U.S. GAAP states that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants.  Fair value measurements are not adjusted for transaction costs.  A fair value hierarchy exists within U.S. GAAP that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements). The three levels of the fair value hierarchy are described below:

29

Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

Level 2 -  Quoted prices for similar assets or liabilities in active markets, quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability;

Level 3 - Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity).

A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.

The types of instruments valued based on quoted market prices in active markets include most U.S. government and agency securities, many other sovereign government obligations, liquid mortgage products, active listed equities and most money market securities. Such instruments are generally classified within level 1 or level 2 of the fair value hierarchy.  The Company does not adjust the quoted price for such instruments.

The types of instruments valued based on quoted prices in markets that are not active, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency include most investment-grade and high-yield corporate bonds, less liquid mortgage products, less liquid agency securities, less liquid listed equities, state, municipal and provincial obligations, and certain physical commodities. Such instruments are generally classified within level 2 of the fair value hierarchy.

Level 3 is for positions that are not traded in active markets or are subject to transfer restrictions, valuations are adjusted to reflect illiquidity and/or non-transferability, and such adjustments are generally based on available market evidence. In the absence of such evidence, management’s best estimate will be used. Management’s best estimate consists of both internal and external support on certain Level 3 investments. Subsequent to inception, management only changes level 3 inputs and assumptions when corroborated by evidence such as transactions in similar instruments, completed or pending third-party transactions in the underlying investment or comparable entities, subsequent rounds of financing, recapitalizations and other transactions across the capital structure, offerings in the equity or debt markets, and changes in financial ratios or cash flows.

For the nine months ended September 30, 2011, the Company has made no transfers of assets between Level 1 and Level 2, and has had no Level 3 activity.

The following tables set forth the Company’s financial assets and liabilities measured on a recurring basis that were accounted for at fair value.  Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement (in thousands):

Certain common equity securities are reported at fair value utilizing Level 1 inputs (exchange quoted prices).  The majority of the other investment securities are reported at fair value utilizing Level 2 inputs.  The prices for these instruments are obtained through an independent pricing service or dealer market participants with whom the Company has historically transacted both purchases and sales of investment securities.  Prices obtained from these sources include prices derived from market quotations and matrix pricing.  The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things.  Management reviews the methodologies used in pricing the securities by its third party providers.

U.S. GAAP requires disclosure of assets and liabilities measured and recorded at fair value on a nonrecurring basis such as goodwill, loans held for sale, other real estate owned, lease residuals, collateral-dependent impaired loans, mortgage servicing rights, and held-to-maturity securities.  The only nonrecurring fair value measurement recorded during the nine month period ended September 30, 2011 was related to impaired loans.  During the nine month period ended September 30, 2011, the Company did not establish additional specific reserves on impaired loans.  The Company uses the fair value of underlying collateral, less costs to sell, to estimate the specific reserves for collateral dependent impaired loans.  Based on the valuation techniques used, the fair value measurements for collateral dependent impaired loans are classified as Level 3.

(1)  Lease receivables, although excluded from the scope of ASC 825-10-50-10, are included in the estimated fair value  amounts at their carrying amounts.

Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

Fair value estimates are based on existing on and off balance sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. For example, the Company has a substantial trust and investment management operation that contributes net fee income annually. The trust and investment management operation is not considered a financial instrument, and its value has not been incorporated into the fair value estimates. Other significant assets and liabilities include the benefits resulting from the low-cost funding of deposit liabilities as compared to the cost of borrowing funds in the market, and premises and equipment. In addition, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in the estimate of fair value.

Declines in the fair value of held-to-maturity and available-for-sale securities below their cost that are deemed to be other than temporary are reflected in earnings as realized losses or in other comprehensive income, depending on whether the Company intends to sell the security or more likely than not will be required to sell the security before recovery of its amortized cost basis less any current-period credit loss.  If the Company intends to sell the security or more likely than not will be required to sell the security before recovery of its amortized cost basis less any current-period credit loss, the other-than-temporary impairment shall be recognized in earnings equal to the entire difference between the investment’s amortized cost basis and its fair value at the balance sheet date.  If the Company does not intend to sell the security and it is not more likely than not that the entity will be required to sell the security before recovery of its amortized cost basis less any current-period credit loss, the other-than-temporary impairment shall be separated into (a) the amount representing the credit loss and (b) the amount related to all other factors.  The amount of the total other-than-temporary impairment related to the credit loss shall be recognized in earnings. The amount of the total other-than-temporary impairment related to other factors shall be recognized in other comprehensive income, net of applicable taxes.

In estimating other-than-temporary impairment losses, management considers, among other things, (i) the length of time and the extent to which the fair value has been less than cost, (ii) the financial condition and near-term prospects of the issuer, and (iii) the historical and implied volatility of the fair value of the security.

35

Management has the intent to hold the securities classified as held to maturity until they mature, at which time it is believed the Company will receive full value for the securities. Furthermore, as of September 30, 2011, management also had the intent to hold, and will not be required to sell, the securities classified as available for sale for a period of time sufficient for a recovery of cost, which may be until maturity.  The unrealized losses are due to increases in market interest rates over the yields available at the time the underlying securities were purchased. When necessary, the Company has performed a discounted cash flow analysis to determine whether or not it will receive the contractual principal and interest on certain securities.  The fair value is expected to recover as the bonds approach their maturity date or repricing date or if market yields for such investments decline.  As of September 30, 2011, management believes the impairments detailed in the table above are temporary and no other-than-temporary impairment losses have been realized in the Company’s consolidated statements of income.

The following tables set forth information with regard to contractual maturities of debt securities at September 30, 2011:

Maturities of mortgage-backed, collateralized mortgage obligations and asset-backed securities are stated based on their estimated average lives.  Actual maturities may differ from estimated average lives or contractual maturities because, in certain cases, borrowers have the right to call or prepay obligations with or without call or prepayment penalties.

Except for U.S. Government related securities, there were no holdings, when taken in the aggregate, of any single issuer that exceeded 10% of consolidated stockholders’ equity at September 30, 2011.

NBT BANCORP INC. AND SUBSIDIARIES

Item 2 -- MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The purpose of this discussion and analysis is to provide a concise description of the financial condition and results of operations of NBT Bancorp Inc. and its wholly owned consolidated subsidiaries, NBT Bank, N.A. (the “Bank”), NBT Financial Services, Inc. (“NBT Financial”), and NBT Holdings, Inc. (“NBT Holdings”) (collectively referred to herein as the “Company”). This discussion will focus on results of operations, financial condition, capital resources and asset/liability management. Reference should be made to the Company's consolidated financial statements and footnotes thereto included in this Form 10-Q as well as to the Company's Annual Report on Form 10-K for the year ended December 31, 2010 for an understanding of the following discussion and analysis.  Operating results for the three and nine month periods ended September 30, 2011 are not necessarily indicative of the results of the full year ending December 31, 2011 or any future period.

Forward-looking Statements

Certain statements in this filing and future filings by the Company with the Securities and Exchange Commission, in the Company’s press releases or other public or shareholder communications, contain forward-looking statements, as defined in the Private Securities Litigation Reform Act. These statements may be identified by the use of phrases such as “anticipate,” “believe,” “expect,” “forecasts,” “projects,” “could,” or other similar terms.   There are a number of factors, many of which are beyond the Company’s control, that could cause actual results to differ materially from those contemplated by the forward-looking statements. Factors that may cause actual results to differ materially from those contemplated by such forward-looking statements include, among others, the following: (1) competitive pressures among depository and other financial institutions may increase significantly; (2) revenues may be lower than expected; (3) changes in the interest rate environment may affect interest margins; (4) general economic conditions, either nationally or regionally, may be less favorable than expected, resulting in, among other things, a deterioration in credit quality and/or a reduced demand for credit; (5) legislative or regulatory changes, including changes in accounting standards or tax laws, may adversely affect the businesses in which the Company is engaged; (6) competitors may have greater financial resources and develop products that enable such competitors to compete more successfully than the Company; (7) adverse changes may occur in the securities markets or with respect to inflation; (8) acts of war or terrorism; (9) the costs and effects of litigation and of unexpected or adverse outcomes in such litigation; (10) internal control failures; and (11) the Company’s success in managing the risks involved in the foregoing.

The Company cautions readers not to place undue reliance on any forward-looking statements, which speak only as of the date made, and advises readers that various factors, including those described above and other factors discussed in the Company’s annual and quarterly reports previously filed with the Securities and Exchange Commission, could affect the Company’s financial performance and could cause the Company’s actual results or circumstances for future periods to differ materially from those anticipated or projected.

Unless required by law, the Company does not undertake, and specifically disclaims any obligations to publicly release any revisions to any forward-looking statements to reflect the occurrence of anticipated or unanticipated events or circumstances after the date of such statements.

Critical Accounting Policies

Management of the Company considers the accounting policy relating to the allowance for loan and lease losses to be a critical accounting policy given the judgment in evaluating the level of the allowance required to cover credit losses inherent in the loan and lease portfolio and the material effect that such judgments can have on the results of operations. While management’s current evaluation of the allowance for loan and lease losses indicates that the allowance is adequate, under different conditions or assumptions, the allowance may need to be increased or decreased. For example, if historical loan and lease loss experience significantly changed or if current economic conditions deteriorated or improved, particularly in the Company’s primary market area, provisions for loan and lease losses may be increased or decreased to adjust the allowance. In addition, the assumptions and estimates relating to loss experience, ability to collect and economic conditions used in the internal reviews of the Company’s nonperforming loans and potential problem loans has a significant impact on the overall analysis of the adequacy of the allowance for loan and lease losses. While management has concluded that the current evaluation of collateral values is reasonable under the circumstances, if collateral valuations were significantly changed, the Company’s allowance for loan and lease policy may require increases or decreases in the provision for loan and lease losses.

Management of the Company considers the accounting policy relating to pension accounting to be a critical accounting policy. Management is required to make various assumptions in valuing its pension assets and liabilities. These assumptions include the expected rate of return on plan assets, the discount rate, and the rate of increase in future compensation levels. Changes to these assumptions could impact earnings in future periods. The Company takes into account the plan asset mix, funding obligations, and expert opinions in determining the various rates used to estimate pension expense. The Company also considers relevant indices and market interest rates in setting the appropriate discount rate. In addition, the Company reviews expected inflationary and merit increases to compensation in determining the rate of increase in future compensation levels.

Management of the Company considers the accounting policy relating to other-than-temporary impairment to be a critical accounting policy.  Management systematically evaluates certain assets for other-than-temporary declines in fair value, primarily investment securities.  Management considers historical values and current market conditions as a part of the assessment.  The amount of the total other-than-temporary impairment related to the credit loss is recognized in earnings and the amount of the total other-than-temporary impairment related to other factors is recognized in other comprehensive income, net of applicable taxes.

Overview

Significant factors management reviews to evaluate the Company’s operating results and financial condition include, but are not limited to:  net income and earnings per share, return on assets and equity, net interest margin, noninterest income, operating expenses, asset quality indicators, loan and deposit growth, capital management, liquidity and interest rate sensitivity, enhancements to customer products and services, technology advancements, market share and peer comparisons.  The following information should be considered in connection with the Company's results for the first nine months of 2011:

· Net income for the nine months ended September 30, 2011 was $44.2 million, up $1.2 million, or 2.8%, from the nine months ended September 30, 2010.  Net income per diluted share for the nine months ended September 30, 2011 was $1.29 per share, up $0.04 from the nine months ended September 30, 2010.

· Net interest margin (on a fully taxable equivalent basis (“FTE”)) was 4.13% for the nine months ended September 30, 2011 as compared to 4.17% for the same period in 2010.

· Certain capital ratios decreased slightly during the nine months ended September 30, 2011 due in large part to the repurchase of approximately $30.5 million of common stock:

38

● Tier 1 Leverage ratio increased from 9.16% to 9.21%

● Tier 1 Capital ratio decreased from 12.44% to 12.00%

● Total Risk-Based Capital Ratio decreased from 13.70% to 13.25%

· Past due loans as a percentage of total loans improved notably to 0.68% at September 30, 2011, as compared with 0.86% at December 31, 2010.

· Net charge-offs were 0.55% of average loans and leases for the first nine months of 2011, down 10 bps from 0.65% for the first nine months of 2010.

· The provision for loan and lease losses was $15.2 million for the nine months ended September 30, 2011, down from $23.1 million for the same period in 2010.

· Annualized return on average assets was 1.09% for the nine months ended September 30, 2011, up from 1.05% for the nine months ended September 30, 2010.

· Noninterest income decreased slightly from $61.7 million for the nine months ended September 30, 2010 to $60.2 million for the nine months ended September 30, 2011.  Service charges on deposit accounts were down $2.3 million, or 12.6%, for the nine months ended September 30, 2011 as compared with the nine months ended September 30, 2010 as a result of the effects of implementing new regulations regarding overdraft fees in the third quarter of 2010.  This decrease was offset by increases in insurance and other financial services revenue, trust income, and ATM and debit card fees.

· Continued strategic expansion with the successful acquisition of four branches in Berkshire County, Massachusetts on October 21, 2011, and the announcement of the purchase of three additional branches in Greene County, New York and deposits and loans in Schoharie County, New York on October 25, 2011.  This transaction is expected to close during the first quarter of 2012, subject to regulatory approval

The following table depicts several annualized measurements of performance using U.S. GAAP net income that management reviews in analyzing the Company’s performance. Returns on average assets and average equity measure how effectively an entity utilizes its total resources and capital, respectively. Net interest margin, which is the net federal taxable equivalent (FTE) interest income divided by average earning assets, is a measure of an entity's ability to utilize its earning assets in relation to the cost of funding. Interest income for tax-exempt securities and loans is adjusted to a taxable equivalent basis using the statutory Federal income tax rate of 35%.

2011	First  Quarter			Second  Quarter			Third Quarter			Nine  Months
Return on average assets (ROAA)		1.08	%		1.09	%		1.12	%		1.09	%
Return on average equity (ROAE)		10.78	%		10.86	%		11.21	%		10.95	%
Net Interest Margin		4.11	%		4.13	%		4.14	%		4.13	%
2010
Return on average assets (ROAA)		1.03	%		1.06	%		1.07	%		1.05	%
Return on average equity (ROAE)		11.05	%		11.09	%		10.89	%		11.01	%
Net Interest Margin		4.21	%		4.14	%		4.15	%		4.17	%

Net Interest Income

Net interest income is the difference between interest income on earning assets, primarily loans and securities, and interest expense on interest bearing liabilities, primarily deposits and borrowings.  Net interest income is affected by the interest rate spread, the difference between the yield on earning assets and cost of interest bearing liabilities, as well as the volumes of such assets and liabilities. Net interest income is one of the key determining factors in a financial institution’s performance as it is the principal source of earnings.

FTE net interest income decreased $0.4 million, or 0.8%, during the three months ended September 30, 2011, compared to the same period of 2010.  The decrease in FTE net interest income resulted primarily from a decrease in the yield on interest earning assets of 27 bp to 4.90% for the three months ended September 30, 2011 from 5.17% for the same period in 2010.  This decrease was partially offset by a decrease of 28 bp on the rate paid on interest bearing liabilities for the three months ended September 30, 2011 period as compared to the same period in 2010. The interest rate spread increased to 3.91% during the three months ended September 30, 2011 compared to 3.90% for the same period in 2010.  The net interest margin decreased by 1 bp to 4.14% for the three months ended September 30, 2011, compared with 4.15% for the same period in 2010.

For the three months ended September 30, 2011, total interest income decreased $3.5 million, or 5.6%, from the same period in 2010 primarily as a result of the decrease in the yield earned on earning assets.  The yield on securities available for sale decreased 54 bp to 2.95% for the three months ended September 30, 2011 from 3.49% for the three months ended September 30, 2010.  This decrease was due to the decreasing rate environment from September 30, 2010 to September 30, 2011 resulting in reinvestment of cash flows from maturing securities into lower yielding securities.  In addition, the yield on loans and leases decreased 34 bp to 5.51% for the three months ended September 30, 2011 from 5.85% for the three months ended September 30, 2010.  Average interest earning assets decreased approximately $25.8 million, or 0.5%, for the three months ended September 30, 2011 as compared to the same period in 2010, which also contributed to the decrease in total interest income.

For the three months ended September 30, 2011, total interest expense decreased $3.3 million, or 25.7%, from the three months ended September 30, 2010.  This decrease was due in large part to a decrease in average interest bearing liabilities of $177.1 million, or 4.5%, for the three months ended September 30, 2011 as compared with the three months ended September 30, 2010.  The lower average balance was due primarily to a decrease in average long-term debt for the three months ended September 30, 2011 as the Company paid down long term borrowings in the second half of 2010, in addition to lower total average interest bearing deposits, which decreased $115.6 million, or 3.5%, for the three months ended September 30, 2011 when compared to the same period in 2010.

The aforementioned decrease in total interest expense was also due to the decrease in the rate paid on average interest bearing liabilities from 1.27% for the three months ended September 30, 2010 to 0.99% for the three months ended September 30, 2011.  The rate paid on average interest bearing deposits decreased 20 bp from 0.87% for the three months ended September 30, 2010 to 0.67% for the same period in 2011.  The rate paid on average time deposits decreased from 2.00% for the three months ended September 30, 2010 to 1.75% for the three months ended September 30, 2011.  The rate paid on average money market deposit accounts decreased from 0.53% for the three months ended September 30, 2010 to 0.31% for the three months ended September 30, 2011.  Going forward, additional rate reductions on deposits could be more difficult as deposit rates are at or near their floors.

Total average borrowings, including trust preferred debentures, decreased $61.4 million, or 9.0%, for the three months ended September 30, 2011 compared with the same period in 2010, primarily due to the aforementioned pay down of long term borrowings.  Given the funds sold position, the Company elected to prepay FHLB borrowings during 2009 and 2010.  The rate paid on long-term debt decreased slightly to 3.88% for the three months ended September 30, 2011 as compared to 3.90% for the three months ended September 30, 2010.  As a result of the decrease in the average balance, interest paid on long-term debt decreased $0.8 million, or 17.2%, for the three months ended September 30, 2011 as compared to the same period in 2010.

FTE net interest income decreased $3.0 million, or 1.9%, during the nine months ended September 30, 2011, compared to the same period of 2010.  The decrease in FTE net interest income resulted primarily from a decrease in the yield on interest earning assets of 33 bp to 4.94% for the nine months ended September 30, 2011 from 5.27% for the same period in 2010.  This decrease was partially offset by a decrease of 31 bp on the rate paid on interest bearing liabilities for the nine months ended September 30, 2011 period as compared to the same period in 2010. The interest rate spread decreased 2 bp during the nine months ended September 30, 2011 compared to the same period in 2010.  The net interest margin decreased by 4 bp to 4.13% for the nine months ended September 30, 2011, compared with 4.17% for the same period in 2010.

For the nine months ended September 30, 2011, total interest income decreased $13.3 million, or 6.9%, from the same period in 2010 primarily as a result of the decrease in the yield earned on earning assets.  The yield on securities available for sale decreased 68 bp to 3.06% for the nine months ended September 30, 2011 from 3.74% for the nine months ended September 30, 2010.  This decrease was due to the decreasing rate environment from September 30, 2010 to September 30, 2011 resulting in reinvestment of cash flows from maturing securities into lower yielding securities.  In addition, the yield on loans and leases decreased 29 bp to 5.63% for the nine months ended September 30, 2011 from 5.92% for the nine months ended September 30, 2010.  Average interest earning assets decreased approximately $48.9 million, or 1.0%, for the nine months ended September 30, 2011 as compared to the same period in 2010, which also contributed to the decrease in total interest income.

For the nine months ended September 30, 2011, total interest expense decreased $11.0 million, or 26.7%, from the nine months ended September 30, 2010.  This decrease was due in large part to a decrease in average interest bearing liabilities of $217.8 million, or 5.4%, for the nine months ended September 30, 2011 as compared with the nine months ended September 30, 2010.  The lower average balance was due primarily to a decrease in average long-term debt for the nine months ended September 30, 2011 as the Company paid down long term borrowings in the second half of 2010, in addition to lower total average interest bearing deposits, which decreased $94.7 million, or 2.8%, for the nine months ended September 30, 2011 when compared to the same period in 2010.

The aforementioned decrease in total interest expense was also due to the decrease in the rate paid on average interest bearing liabilities from 1.36% for the nine months ended September 30, 2010 to 1.05% for the nine months ended September 30, 2011.  The rate paid on average interest bearing deposits decreased 21 bp from 0.94% for the nine months ended September 30, 2010 to 0.73% for the same period in 2011.  The rate paid on average time deposits decreased from 2.10% for the nine months ended September 30, 2010 to 1.83% for the nine months ended September 30, 2011.  The rate paid on average money market deposit accounts decreased from 0.62% for the nine months ended September 30, 2010 to 0.37% for the nine months ended September 30, 2011.  Going forward, additional rate reductions on deposits could be more difficult as deposit rates are at or near their floors.

Total average borrowings, including trust preferred debentures, decreased $123.1 million, or 17.0%, for the nine months ended September 30, 2011 compared with the same period in 2010, primarily due to the aforementioned pay down of long term borrowings.  Given the funds sold position, the Company elected to prepay FHLB borrowings during 2009 and 2010.  The rate paid on long-term debt increased slightly to 3.90% for the nine months ended September 30, 2011 as compared to 3.89% for the nine months ended September 30, 2010.  As a result of the decrease in the average balance, interest paid on long-term debt decreased $3.5 million, or 24.5%, for the nine months ended September 30, 2011 as compared to the same period in 2010.

	Three months ended September 30,				Nine months ended September 30,
	2011		2010		2011		2010

Noninterest income for the three months ended September 30, 2011 was $20.2 million, down slightly from $21.0 million for the same period in 2010.  Insurance and other financial services revenue increased approximately $0.5 million for the three months ended September 30, 2011, as compared to the three months ended September 30, 2010, due primarily to the acquisition of an insurance agency during the second quarter of 2011.  ATM and debit card fees also increased approximately $0.5 million for the three months ended September 30, 2011, as compared to the three months ended September 30, 2010 due to an increase in card usage as well as a change in the fee structure on foreign ATM transactions.  Trust revenue increased approximately $0.3 million for the three months ended September 30, 2011, as compared to the three months ended September 30, 2010, due primarily to the addition of new business generated from markets where we have recently expanded, and an increase in the fair market value of trust assets under administration.    These increases were offset by a decrease in service charges on deposit accounts of approximately $0.4 million, or 7.1%, for the three months ended September 30, 2011, as compared with the same period in 2010.  The decrease in service charges was the result of a decrease in overdraft activity due to customer awareness and the current state of the economy.  In addition, retirement plan administration fees decreased by $0.3 million, or 12.1%, for the three months ended September 30, 2011 as compared to the same period in 2010, driven by the loss of one client in the fourth quarter of 2010.  This decrease was partially offset by increases from new business and market-based fees during 2011.  Net securities gains decreased by $1.1 million for the three months ended September 30, 2011 as compared to the same period in 2010 due to gains on certain securities sales during the third quarter of 2010.

Noninterest income for the nine months ended September 30, 2011 was $60.2 million, down slightly from $61.7 million for the same period in 2010.  Insurance and other financial services revenue increased approximately $1.4 million for the nine months ended September 30, 2011, as compared to the nine months ended September 30, 2010, due primarily to the aforementioned acquisition of an insurance agency during the second quarter of 2011 and an increase in brokerage commission revenue due to new business.  ATM and debit card fees increased approximately $1.2 million for the nine months ended September 30, 2011, as compared to the nine months ended September 30, 2010 due to an increase in card usage as well as a change in the fee structure on foreign ATM transactions.  Trust revenue increased approximately $0.9 million for the nine months ended September 30, 2011, as compared to the nine months ended September 30, 2010, due primarily to the addition of new business generated from markets where we have recently expanded, and an increase in the fair market value of trust assets under administration.    These increases were offset by a decrease in service charges on deposit accounts of approximately $2.3 million, or 12.6%, for the nine months ended September 30, 2011, as compared with the same period in 2010.  The decrease in service charges was the result of a decrease in overdraft activity due to the effects of implementing new regulations regarding overdraft fees in the third quarter of 2010, as well as the current state of the economy.  In addition, retirement plan administration fees decreased by $0.9 million, or 11.4%, for the nine months ended September 30, 2011 as compared to the same period in 2010, driven by the loss of one client in the fourth quarter of 2010.  This decrease was partially offset by increases from new business and market-based fees during 2011.  Net securities gains decreased by $1.1 million for the nine months ended September 30, 2011 as compared to the same period in 2010 due to gains on certain securities sales in 2010.

Noninterest expense for the three months ended September 30, 2011 was $45.0 million, up slightly from $44.7 million, or 0.8%, for the same period in 2010.  Salaries and employee benefits increased $1.0 million, or 4.1%, for the three months ended September 30, 2011, compared with the same period in 2010.  This increase was due primarily to increases in full-time-equivalent employees, merit increases and other employee benefits.  Other operating expenses increased approximately $0.6 million for the three months ended September 30, 2011, as compared to the same period in 2010, primarily as a result of flood and merger related expenses during the third quarter of 2011.  These increases were offset by a decrease in Federal Deposit Insurance Corporation (FDIC) premium expenses of approximately $0.7 million for the three months ended September 30, 2011 as compared to the same period in 2010, due to the FDIC redefining the deposit insurance assessment base.  In addition, the Company incurred a debt prepayment penalty of $1.2 million to pay off long-term debt during the third quarter of 2010, while no prepayment penalties were incurred for the same period in 2011.

Noninterest expense for the nine months ended September 30, 2011 was $133.3 million, up from $131.0 million, or 1.7%, for the same period in 2010.  Salaries and employee benefits increased $3.6 million, or 5.1%, for the nine months ended September 30, 2011, compared with the same period in 2010.  This increase was due primarily to increases in full-time-equivalent employees, merit increases and other employee benefits.  In addition, occupancy expenses increased approximately $0.9 million for the nine months ended September 30, 2011, as compared to the same period in 2010, primarily due to continued branch expansion and expenses related to the harsh winter.  Other operating expenses increased approximately $0.9 million for the nine months ended September 30, 2011, as compared to the same period in 2010, primarily as a result of flood and merger related expenses during the third quarter of 2011.  

46

These increases were partially offset by a decrease in FDIC premium expenses of approximately $1.4 million for the first nine months of 2011 as compared to the same period in 2010 due to the aforementioned FDIC redefined deposit insurance assessment base.  In addition, the Company incurred a debt prepayment penalty of $1.2 million to pay off long-term debt during the third quarter of 2010, while no prepayment penalties were incurred for the same period in 2011.  Data processing and communications expenses decreased approximately $0.4 million for the nine months ended September 30, 2011, as compared to the nine months ended September 30, 2010.  This decrease was due to the renegotiation of a data processing contract resulting in a decrease in processing fees.  In addition, loan collection and other real estate owned expenses decreased approximately $0.4 million for the nine months ended September 30, 2011, as compared to the nine months ended September 30, 2010, due primarily to a reduction in properties classified as other real estate owned resulting in a reduction in maintenance expenses on those properties.

Income Taxes

Income tax expense for the three month period ended September 30, 2011 was $5.1 million, up from $4.8 million for the same period in 2010.  The effective tax rate was 25.2% for the three months ended September 30, 2011, as compared to 24.9% for the same period in 2010.  During the three months ended September 30, 2011, a reduction in the Company’s tax provision was driven by a reduction of tax reserves of $0.8 million, no longer required due to the expiration of the related statute of limitations.

Income tax expense for the nine month period ended September 30, 2011 was $17.4 million, up from $16.5 million for the same period in 2010.  The effective tax rate was 28.2% for the nine months ended September 30, 2011, as compared to 27.8% for the same period in 2010.

ANALYSIS OF FINANCIAL CONDITION

Securities

The Company classifies its securities at date of purchase as available for sale, held to maturity or trading.  Held to maturity debt securities are those that the Company has the ability and intent to hold until maturity.  Held to maturity securities are recorded at amortized cost.  Available for sale securities are recorded at fair value.  Unrealized holding gains and losses, net of the related tax effect, on available for sale securities are excluded from earnings and are reported in stockholders’ equity as a component of accumulated other comprehensive income or loss.  For the securities that the Company does not have the intent to sell and will not be more likely than not required to sell, the amount of the total other-than-temporary impairment related to the credit loss is recognized in earnings and the amount of the total other-than-temporary impairment related to other factors is recognized in other comprehensive income, net of applicable taxes.  Securities with an other-than-temporary impairment are generally placed on nonaccrual status.  Trading securities are recorded at fair value, with net unrealized gains and losses recognized currently in income.  Transfers of securities between categories are recorded at fair value at the date of transfer.

Average total earning securities decreased $30.4 million, or 2.6%, for the three months ended September 30, 2011 when compared to the same period in 2010.  The average balance of securities available for sale increased $67.1 million, or 6.4%, for the three months ended September 30, 2011 when compared to the same period in 2010.  The average balance of securities held to maturity decreased $36.7 million, or 33.0%, for the three months ended September 30, 2011, compared to the same period in 2010.  This decrease was due primarily to the scheduled run-off of municipal securities in the held to maturity portfolio.  The average total securities portfolio represents 24.2% of total average earning assets for the three months ended September 30, 2011, up from 23.5% for the same period in 2010.

47

Average total earning securities decreased $33.1 million, or 2.7%, for the nine months ended September 30, 2011 when compared to the same period in 2010.  The average balance of securities available for sale increased $20.6 million, or 1.9%, for the nine months ended September 30, 2011 when compared to the same period in 2010.  The average balance of securities held to maturity decreased $53.7 million, or 38.8%, for the nine months ended September 30, 2011, compared to the same period in 2010.  This decrease was due primarily to the scheduled run-off of municipal securities in the held to maturity portfolio.  The average total securities portfolio represents 24.0% of total average earning assets for the nine months ended September 30, 2011, down from 24.4% for the same period in 2010.

The following table details the composition of securities available for sale, securities held to maturity and regulatory investments for the periods indicated:

	September 30,  2011			December 31, 2010
Mortgage-backed securities:
With maturities 15 years or less		22	%		16	%
With maturities greater than 15 years		3	%		4	%
Collateral mortgage obligations		32	%		24	%
Municipal securities		14	%		17	%
US agency notes		24	%		35	%
Other		5	%		4	%
Total		100	%		100	%

The Company’s mortgage backed securities, U.S. agency notes, and collateralized mortgage obligations are all “prime/conforming” and are guaranteed by Fannie Mae, Freddie Mac, Federal Home Loan Bank, Federal Farm Credit Banks, or Ginnie Mae (“GNMA”).  GNMA securities are considered equivalent to U.S. Treasury securities, as they are backed by the full faith and credit of the U.S. government.  Currently, there are no subprime mortgages in our investment portfolio.

During the nine months ended September 30, 2011, the Company experienced a shift from U.S. agency notes to mortgage-backed securities and collateral mortgage obligations.  As of September 30, 2011, mortgage-backed securities with maturities of 15 years or less comprised 22% of the securities portfolio as compared to 16% as of December 31, 2010.  As of September 30, 2011, US agency notes comprised 24% of the Company’s securities as compared to 35% as of December 31, 2010.

Loans and Leases

A summary of loans and leases, net of deferred fees and origination costs, by category for the periods indicated follows:

(In thousands)	September 30,  2011		December 31, 2010
Residential real estate mortgages	$	570,448	$	548,394
Commercial		608,675		577,731
Commercial real estate mortgages		867,258		844,458

Home equity		552,925		575,678
Total loans and leases	$	3,708,090	$	3,610,006

Total loans and leases increased by $98.1 million, or 2.7%, at September 30, 2011 from December 31, 2010, and represent approximately 67.7% of assets, as compared to 67.6% of total assets at December 31, 2010.  Commercial loans increased approximately $30.9 million, or 5.4%, from December 31, 2010 to September 30, 2011.  Real estate construction and development loans increased by approximately $20.6 million, or 45.4%, from December 31, 2010 to September 30, 2011, due primarily to the origination of three large construction loans during the nine months ended September 30, 2011.  These increases were slightly offset by a decrease in home equity loans of approximately $22.8 million, or 4.0%, from December 31, 2010 to September 30, 2011.

Allowance for Loan and Lease Losses, Provision for Loan and Lease Losses, and Nonperforming Assets

The allowance for loan and lease losses is maintained at a level estimated by management to provide adequately for risk of probable losses inherent in the current loan and lease portfolio.  The adequacy of the allowance for loan and lease losses is continuously monitored using a methodology designed to ensure that the level of the allowance reasonably reflects the loan portfolio’s risk profile. It is evaluated to ensure that it is sufficient to absorb all reasonably estimable credit losses inherent in the current loan and lease portfolio.

Management considers the accounting policy relating to the allowance for loan and lease losses to be a critical accounting policy given the degree of judgment exercised in evaluating the level of the allowance required to cover credit losses in the portfolio and the material effect that such judgments can have on the consolidated results of operations.

For purposes of evaluating the adequacy of the allowance, the Company considers a number of significant factors that affect the collectibility of the portfolio.  For individually analyzed loans, these factors include estimates of loss exposure, which reflect the facts and circumstances that affect the likelihood of repayment of such loans as of the evaluation date.  For homogeneous pools of loans and leases, estimates of the Company’s exposure to credit loss reflect a thorough current assessment of a number of factors, which could affect collectibility. These factors include: past loss experience; the size, trend, composition, and nature of the loans and leases; changes in lending policies and procedures, including underwriting  standards and collection, charge-off and recovery practices;  trends experienced in nonperforming and delinquent loans and leases; current economic conditions in the Company’s market; portfolio concentrations that may affect loss experienced across one or more components of the portfolio; the effect of external factors such as competition, legal and regulatory requirements; and the experience, ability, and depth of lending management and staff.  In addition, various regulatory agencies, as an integral component of their examination process, periodically review the Company’s allowance for loan and lease losses.  Such agencies may require the Company to recognize additions to the allowance based on their judgment about information available to them at the time of their examination, which may not be currently available to management.

After a thorough consideration and validation of the factors discussed above, required additions or reductions to the allowance for loan and lease losses are made periodically by charges or credits to the provision for loan and lease losses.  These charges are necessary to maintain the allowance at a level which management believes is reasonably reflective of the overall inherent risk of probable loss in the portfolio.  While management uses available information to recognize losses on loans and leases, additions or reductions to the allowance may fluctuate from one reporting period to another.  These fluctuations are reflective of changes in risk associated with portfolio content and/or changes in management’s assessment of any or all of the determining factors discussed above.  The allowance for loan and lease losses related to commercial loans decreased by approximately $1.2 million from December 31, 2010 to September 30, 2011 due primarily to the charge-off of one large commercial credit during the period that had been specifically reserved for.  The allowance for loan and lease losses related to residential real estate mortgages increased by $1.3 million from December 31, 2010 to September 30, 2011, due primarily to environmental and economic conditions related to the September 2011 flood within the Company’s footprint.  The allowance for loan and lease losses to outstanding loans and leases decreased slightly to 1.92% as of September 30, 2011 as compared to 1.97% at December 31, 2010.  Management considers the allowance for loan losses to be adequate based on evaluation and analysis of the loan portfolio.

49

The following table reflects changes to the allowance for loan and lease losses for the periods presented. The allowance is increased by provisions for losses charged to operations and is reduced by net charge-offs. Charge-offs are made when the ability to collect loan principal within a reasonable time becomes unlikely. Any recoveries of previously charged-off loans are credited directly to the allowance for loan and lease losses.

Nonperforming assets consist of nonaccrual loans, loans 90 days or more past due and still accruing, restructured loans, OREO, and nonperforming securities. Loans are generally placed on nonaccrual when principal or interest payments become ninety days past due, unless the loan is well secured and in the process of collection. Loans may also be placed on nonaccrual when circumstances indicate that the borrower may be unable to meet the contractual principal or interest payments. OREO represents property acquired through foreclosure and is valued at the lower of the carrying amount or fair value, less any estimated disposal costs.  Nonperforming securities include securities which management believes are other-than-temporarily impaired, are carried at their estimated fair value and are not accruing interest.

Loans over 60 days past due but not over 90 days past due were 0.11% of total loans as of September 30, 2011, compared to 0.15% of total loans as of December 31, 2010.  In addition to nonperforming loans, the Company has also identified approximately $96.7 million in potential problem loans at September 30, 2011 as compared to $82.2 million at December 31, 2010.  Potential problem loans are loans that are currently performing, but known information about possible credit problems of the borrowers causes management to have serious doubts as to the ability of such borrowers to comply with the present loan repayment terms and which may result in classification of such loans as nonperforming at some time in the future.  Potential problem loans are typically defined as loans that are performing but are classified by the Company’s loan rating system as “substandard.”  At September 30, 2011, potential problem loans primarily consisted of commercial real estate and commercial and agricultural loans.  Potential problem loans were up $14.5 million from December 31, 2011, due primarily to the migration of certain commercial credits to classified status, which management believes have been adequately reserved for in the allowance for loan and lease losses.  Nonaccrual home equity loans increased approximately $2.0 million from December 31, 2010 to September 30, 2011, due primarily to economic conditions.  Management cannot predict the extent to which economic conditions may worsen or other factors which may impact borrowers and the potential problem loans.  Accordingly, there can be no assurance that other loans will not become 90 days or more past due, be placed on nonaccrual, become restructured, or require increased allowance coverage and provision for loan losses.

51

The Company recorded a provision for loan and lease losses of $5.2 million during the third quarter of 2011 compared with $7.5 million during the third quarter of 2010.  Annualized net charge-offs to average loans and leases for the three months ended September 30, 2011 were 0.47%, compared with 0.65% for three months ended September 30, 2010.  The Company’s allowance for loan and lease losses decreased slightly to 1.92% of loans and leases at September 30, 2011, compared with 1.97% at December 31, 2010.  Specific reserves on impaired loans totaled $0.2 million at September 30, 2011 and $2.2 million at December 31, 2010.  General allocations increased slightly to $71.1 million at September 30, 2011 from $69.0 million at December 31, 2010.

The Company recorded a provision for loan and lease losses of $15.2 million during the nine months ended September 30, 2011, which included additional provisions as a result of the September 2011 flooding in the Company’s geographic footprint, compared with $23.1 million during the nine months ended September 30, 2010.  Annualized net charge-offs to average loans and leases for the nine months ended September 30, 2011 were 0.55%, compared with 0.65% for nine months ended September 30, 2010.

Subprime mortgage lending, which has been the riskiest sector of the residential housing market, is not a market that the Company has ever actively pursued.  The market does not apply a uniform definition of what constitutes “subprime” lending.  Our reference to subprime lending relies upon the “Statement on Subprime Mortgage Lending” issued by the Office of Thrift Supervision and the other federal bank regulatory agencies, or the Agencies, on June 29, 2007, which further referenced the “Expanded Guidance for Subprime Lending Programs,” or the Expanded Guidance, issued by the Agencies by press release dated January 31, 2001.  In the Expanded Guidance, the Agencies indicated that subprime lending does not refer to individual subprime loans originated and managed, in the ordinary course of business, as exceptions to prime risk selection standards.  The Agencies recognize that many prime loan portfolios will contain such accounts.  The Agencies also excluded prime loans that develop credit problems after acquisition and community development loans from the subprime arena.  According to the Expanded Guidance, subprime loans are other loans to borrowers which display one or more characteristics of reduced payment capacity.  Five specific criteria, which are not intended to be exhaustive and are not meant to define specific parameters for all subprime borrowers and may not match all markets or institutions’ specific subprime definitions, are set forth, including having a FICO score of 660 or below.  Based upon the definition and exclusions described above, management believes that the Company is a prime lender.  Within the loan portfolio, there are loans that, at the time of origination, had FICO scores of 660 or below.  However, since the Company is a portfolio lender, it reviews all data contained in borrower credit reports and does not base underwriting decisions solely on FICO scores.  We believe the aforementioned loans, when made, were amply collateralized and otherwise conformed to our prime lending standards.  The Company has not originated Alt A loans or no interest loans.

Deposits

Total deposits were $4.3 billion at September 30, 2011, up $130.7 million, or 3.2%, from December 31, 2010.  Savings, NOW and money market accounts increased $73.5 million as of September 30, 2011 as compared with December 31, 2010.  Time deposits decreased $59.6 million, or 6.4%, from December 31, 2010 to September 30, 2011.  Demand deposits increased by $116.8 million, or 12.8%, from December 31, 2010 to September 30, 2011.

Total average deposits for the three months ended September 30, 2011 increased $40.3 million, or 1.0%, from the same period in 2010.  The Company experienced a decrease in average money market accounts of $42.2 million, or 3.9%, for the three months ended September 30, 2011 compared to the same period in 2010.  Average NOW accounts decreased $34.6 million, or 5.2%, for the three months ended September 30, 2011 as compared to the same period in 2010.  Average savings accounts increased $50.3 million, or 8.9%, for the three month period ending September 30, 2011 as compared to the same period in 2010.  This increase in average savings accounts was primarily due to a transition from a run-off of time deposit accounts into savings accounts, due to a decline in interest rates offered on time deposits.  Average time deposits decreased $89.2 million, or 9.2%, for the three months ended September 30, 2011 from the same period in 2010.  Average demand deposit accounts increased $156.0 million, or 18.9%, for the three months ended September 30, 2011 as compared to the same period in 2010.  This was due primarily to an increasing customer base, as the Company continues to expand into new markets.

52

Total average deposits for the nine months ended September 30, 2011 increased $56.5 million, or 1.4%, from the same period in 2010.  The Company experienced a decrease in average money market accounts of $29.9 million, or 2.7%, for the nine months ended September 30, 2011 compared to the same period in 2010.  Average NOW accounts decreased $25.2 million, or 3.6%, for the nine months ended September 30, 2011 as compared to the same period in 2010.  Average savings accounts increased $47.5 million, or 8.6%, for the nine month period ending September 30, 2011 as compared to the same period in 2010.  This increase in average savings accounts was primarily due to the aforementioned transition from a run-off of time deposit accounts into savings accounts, due to a decline in interest rates offered on time deposits.  Average time deposits decreased $87.1 million, or 8.7%, for the nine months ended September 30, 2011 from the same period in 2010.  Average demand deposit accounts increased $151.2 million, or 19.2%, for the nine months ended September 30, 2011 as compared to the same period in 2010.  This was due primarily to an increasing customer base, as the Company continues to expand into new markets.

Borrowed Funds

The Company's borrowed funds consist of short-term borrowings and long-term debt. Short-term borrowings totaled $158.3 million at September 30, 2011 compared to $159.4 million at December 31, 2010.  Long-term debt was $370.3 million at September 30, 2011, as compared to $369.9 million at December 31, 2010.  For more information about the Company’s borrowing capacity and liquidity position, see “Liquidity Risk” below.

Capital Resources

Stockholders' equity of $538.8 million represented 9.84% of total assets at September 30, 2011, compared with $533.6 million, or 9.99% as of December 31, 2010.  Under previously disclosed stock repurchase plans, the Company purchased 1,458,609 shares of its common stock during the nine month period ended September 30, 2011, for a total of $30.5 million at an average price of $20.91 per share.  On July 25, 2011, the NBT Board of Directors authorized a new repurchase program for NBT to repurchase up to 1,000,000 shares (approximately 3%) of its outstanding common stock, effective July 25, 2011, as market conditions warrant in open market and privately negotiated transactions.  At September 30, 2011, there were 517,581 shares available for repurchase under this plan, which expires on December 31, 2013.  On October 24, 2011, the NBT Board of Directors authorized a new repurchase program for NBT to repurchase up to an additional 1,000,000 shares (approximately 3%) of its outstanding common stock, effective October 24, 2011, as market conditions warrant in open market and privately negotiated transactions.  This plan expires on December 31, 2013.

The Board of Directors considers the Company's earnings position and earnings potential when making dividend decisions.  The Company does not have a target dividend pay out ratio.

As the capital ratios in the following table indicate, the Company remained “well capitalized” at September 30, 2011 under applicable bank regulatory requirements.  Capital measurements are well in excess of regulatory minimum guidelines and meet the requirements to be considered well capitalized for all periods presented. Tier 1 leverage, Tier 1 capital and Total risk-based capital ratios have regulatory minimum guidelines of 3%, 4% and 8% respectively, with requirements to be considered well capitalized of 5%, 6% and 10%, respectively.

Liquidity and Interest Rate Sensitivity Management

Market Risk

Interest rate risk is the primary market risk affecting the Company.  Other types of market risk, such as foreign currency exchange rate risk and commodity price risk, do not arise in the normal course of the Company’s business activities.  Interest rate risk is defined as an exposure to a movement in interest rates that could have an adverse effect on the Company’s net interest income.  Net interest income is susceptible to interest rate risk to the degree that interest bearing liabilities mature or reprice on a different basis than earning assets.  When interest bearing liabilities mature or reprice more quickly than earning assets in a given period, a significant increase in market rates of interest could adversely affect net interest income.  Similarly, when earning assets mature or reprice more quickly than interest bearing liabilities, falling interest rates could result in a decrease in net interest income.

In an attempt to manage the Company's exposure to changes in interest rates, management monitors the Company’s interest rate risk.  Management’s Asset Liability Committee (“ALCO”) meets monthly to review the Company’s interest rate risk position and profitability, and to recommend strategies for consideration by the Board of Directors.  Management also reviews loan and deposit pricing and the Company’s securities portfolio, formulates investment and funding strategies, and oversees the timing and implementation of transactions to assure attainment of the Board’s objectives in the most effective manner. Notwithstanding the Company’s interest rate risk management activities, the potential for changing interest rates is an uncertainty that can have an adverse effect on net income.

In adjusting the Company’s asset/liability position, the Board and management attempt to manage the Company’s interest rate risk while minimizing net interest margin compression.  At times, depending on the level of general interest rates, the relationship between long- and short-term interest rates, market conditions and competitive factors, the Board and management may determine to increase the Company’s interest rate risk position somewhat in order to increase its net interest margin.  The Company’s results of operations and net portfolio values remain vulnerable to changes in interest rates and fluctuations in the difference between long- and short-term interest rates.  Assuming interest rates remain at or near current historical lows, net interest margin will continue to experience compression.  Additional rate reductions on deposits are becoming more difficult as deposit rates are at or near their floors, and with asset yields continuing to reprice at lower rates, this could result in additional margin pressure as well as a decrease in net interest income.

The primary tool utilized by ALCO to manage interest rate risk is a balance sheet/income statement simulation model (interest rate sensitivity analysis).  Information such as principal balance, interest rate, maturity date, cash flows, next repricing date (if needed), and current rates is uploaded into the model to create an ending balance sheet.  In addition, ALCO makes certain assumptions regarding prepayment speeds for loans and leases and mortgage related investment securities along with any optionality within the deposits and borrowings.

54

The model is first run under an assumption of a flat rate scenario (i.e. no change in current interest rates) with a static balance sheet over a 12-month period.  Two additional models are run with static balance sheets: (1) a gradual increase of 200 bp, and (2) a gradual decrease of 100 bp taking place over a 12-month period. Under these scenarios, assets subject to prepayments are adjusted to account for faster or slower prepayment assumptions.  Any investment securities or borrowings that have callable options embedded into them are handled accordingly based on the interest rate scenario. The resulting changes in net interest income are then measured against the flat rate scenario.

In the declining rate scenario, net interest income is projected to decrease when compared to the forecasted net interest income in the flat rate scenario through the simulation period. The decrease in net interest income is a result of earning assets repricing downward at a faster rate than interest bearing liabilities. The inability to effectively lower deposit rates will likely reduce or eliminate the benefit of lower interest rates. In the rising rate scenarios, net interest income is projected to experience a decline from the flat rate scenario. Net interest income is projected to remain at lower levels than in a flat rate scenario through the simulation period primarily due to a lag in assets repricing while funding costs increase. The potential impact on earnings is dependent on the ability to lag deposit repricing. If short-term rates continue to increase, the Company expects competitive pressures will likely lead to core deposit pricing increases, which will likely continue compression of the net interest margin.

Net interest income for the next 12 months in the + 200/- 100 bp scenarios, as described above, is within the internal policy risk limits of not more than a 7.5% change in net interest income. The following table summarizes the percentage change in net interest income in the rising and declining rate scenarios over a 12-month period from the forecasted net interest income in the flat rate scenario using the September 30, 2011 balance sheet position:

(in bp points)	net interest income

Liquidity Risk

Liquidity involves the ability to meet the cash flow requirements of customers who may be depositors wanting to withdraw funds or borrowers needing assurance that sufficient funds will be available to meet their credit needs. The ALCO is responsible for liquidity management and has developed guidelines which cover all assets and liabilities, as well as off balance sheet items that are potential sources or uses of liquidity.  Liquidity policies must also provide the flexibility to implement appropriate strategies and tactical actions. Requirements change as loans and leases grow, deposits and securities mature, and payments on borrowings are made. Liquidity management includes a focus on interest rate sensitivity management with a goal of avoiding widely fluctuating net interest margins through periods of changing economic conditions.

The primary liquidity measurement the Company utilizes is called the Basic Surplus, which captures the adequacy of its access to reliable sources of cash relative to the stability of its funding mix of average liabilities.  Basic Surplus is calculated by subtracting short-term liabilities from liquid assets.  This approach recognizes the importance of balancing levels of cash flow liquidity from short- and long-term securities with the availability of dependable borrowing sources which can be accessed when necessary.  At September 30, 2011, the Company’s Basic Surplus measurement was 11.1% of total assets or $610 million as compared to the December 31, 2010 Basic Surplus of 9.7% or $517 million, and was above the Company’s minimum of 5% or $274 million set forth in its liquidity policies.  Since March 2009, the Company has been in a Fed Funds sold position as a result of excess liquidity.

55

This Basic Surplus approach enables the Company to adequately manage liquidity from both operational and contingency perspectives. By tempering the need for cash flow liquidity with reliable borrowing facilities, the Company is able to operate with a more fully invested and, therefore, higher interest income generating securities portfolio. The makeup and term structure of the securities portfolio is, in part, impacted by the overall interest rate sensitivity of the balance sheet. Investment decisions and deposit pricing strategies are impacted by the liquidity position.

The Company’s primary source of funds is the Bank. Certain restrictions exist regarding the ability of the Bank to transfer funds to the Company in the form of cash dividends. The approval of the Office of Comptroller of the Currency (OCC) is required to pay dividends when a bank fails to meet certain minimum regulatory capital standards or when such dividends are in excess of a subsidiary bank’s earnings retained in the current year plus retained net profits for the preceding two years (as defined in the regulations). At September 30, 2011, approximately $87.9 million of the total stockholders’ equity of the Bank was available for payment of dividends to the Company without approval by the OCC.  The Bank’s ability to pay dividends is also subject to the Bank being in compliance with regulatory capital requirements. The Bank is currently in compliance with these requirements. Under the General Corporation Law of the State of Delaware, the Company may declare and pay dividends either out of its surplus or, in case there is no surplus, out of its net profits for the fiscal year in which the dividend is declared and/or the preceding fiscal year.

At September 30, 2011 and December 31, 2010, FHLB advances outstanding totaled $343 million.  The Bank is a member of the FHLB system and had additional borrowing capacity from the FHLB of approximately $328 million at September 30, 2011 and $284 million at December 31, 2010.  In addition, unpledged securities could have been used to increase borrowing capacity at the FHLB by an additional $276 million at September 30, 2011, or used to collateralize other borrowings, such as repurchase agreements.  At September 30, 2011 the Bank also had additional borrowing capacity from unused collateral at the Federal Reserve of $471 million.

Recent Accounting Pronouncements

In September 2011, the FASB issued ASU No. 2011-08 "Intangibles – Goodwill and Other (Topic 350) – Testing Goodwill for Impairment".  ASU 2011-08 is intended to reduce complexity and costs of performing goodwill impairment tests by allowing an entity the option to make a qualitative evaluation about the likelihood of goodwill impairment to determine whether it should calculate the fair value of a reporting unit. The amendments in ASU 2011-08 also improve previous guidance by expanding upon the examples of events and circumstances that an entity should consider between annual impairment tests in determining whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. Also, the amendments improve the examples of events and circumstances that an entity having a reporting unit with a zero or negative carrying amount should consider in determining whether to measure an impairment loss, if any, under the second step of the goodwill impairment test.  The amendments are effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. Early adoption is permitted, including for annual and interim goodwill impairment tests performed as of a date before September 15, 2011, if an entity’s financial statements for the most recent annual or interim period have not yet been issued or, for nonpublic entities, have not yet been made available for issuance.  The Company is assessing the impact of ASU 2011-08 on its goodwill impairment testing procedures.

In May 2011, the FASB issued ASU No. 2011-04 "Fair Value Measurement (Topic 820) - Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs."  ASU 2011-04 changes the wording used to describe many of the requirements in GAAP for measuring fair value and for disclosing information about fair value measurements.  Consequently, the amendments in this update result in common fair value measurement and disclosure requirements in GAAP and IFRSs (International Financial Reporting Standards).  ASU 2011-04 is effective prospectively during interim and annual periods beginning on or after December 15, 2011.  Early application by public entities is not permitted.  The Company is assessing the impact of ASU 2011-04 on its fair value disclosures.

56

In April 2011, the FASB issued ASU No. 2011-03 "Transfers and Servicing (Topic 860) - Reconsideration of Effective Control for Repurchase Agreement."  ASU 2011-03 removes from the assessment of effective control the criterion relating to the transferor's ability to repurchase or redeem financial assets on substantially the agreed terms, even in the event of default by the transferee.  ASU 2011-03 is effective for the first interim or annual period beginning on or after December 15, 2011.  The guidance should be applied prospectively to transactions or modifications of existing transactions that occur on or after the effective date.  Early adoption is not permitted.  The Company believes that the adoption of the standard will not have a significant impact on the Company's consolidated financial statements.

In April 2011, the FASB issued ASU No. 2011-02, “A Creditor’s Determination of Whether a Restructuring Is a Troubled Debt Restructuring (Topic 310)”, was issued in April 2011.  The amendments in this Update provide guidance in evaluating whether a restructuring constitutes a troubled debt restructuring.  A creditor must separately conclude that both of the following exist: 1. The restructuring constitutes a concession. 2. The debtor is experiencing financial difficulties. The amendments to Topic 310 clarify the guidance on a creditor’s evaluation of whether it has granted a concession as follows: 1. If a debtor does not otherwise have access to funds at a market rate for debt with similar risk characteristics as the restructured debt, the restructuring would be considered to be at a below-market rate, which may indicate that the creditor has granted a concession. In that circumstance, a creditor should consider all aspects of the restructuring in determining whether it has granted a concession. If a creditor determines that it has granted a concession, the creditor must make a separate assessment about whether the debtor is experiencing financial difficulties to determine whether the restructuring constitutes a troubled debt restructuring. 2. A temporary or permanent increase in the contractual interest rate as a result of a restructuring does not preclude the restructuring from being considered a concession because the new contractual interest rate on the restructured debt could still be below the market interest rate for new debt with similar risk characteristics. In such situations, a creditor should consider all aspects of the restructuring in determining whether it has granted a concession. If a creditor determines that it has granted a concession, the creditor must make a separate assessment about whether the debtor is experiencing financial difficulties to determine whether the restructuring constitutes a troubled debt restructuring. 3. A restructuring that results in a delay in payment that is insignificant is not a concession. However, an entity should consider various factors in assessing whether a restructuring resulting in a delay in payment is insignificant. The amendments include examples illustrating the assessment of whether a restructuring results in a delay in payment that is insignificant. The amendments to Topic 310 also clarify the guidance on a creditor’s evaluation of whether a debtor is experiencing financial difficulties as follows:  A creditor may conclude that a debtor is experiencing financial difficulties, even though the debtor is not currently in payment default. A creditor should evaluate whether it is probable that the debtor would be in payment default on any of its debt in the foreseeable future without the modification. In addition, the amendments to Topic 310 clarify that a creditor is precluded from using the effective interest rate test in the debtor’s guidance on restructuring of payables when evaluating whether a restructuring constitutes a troubled debt restructuring.  The amendments in this Update are effective for the first interim or annual period beginning on or after June 15, 2011 and should be applied retrospectively to the beginning of the annual period of adoption.  The amendments in this Update require disclosures consistent with its effective date.  The implementation of this amendment did not have a material effect on the Company’s financial statements, but did have a significant effect on disclosures in our interim and annual reports.

PART II.  OTHER INFORMATION

Item 1 – LEGAL PROCEEDINGS

The Bank has been named as a defendant in a purported class action lawsuit arising from its assessment and collection of overdraft fees on its checking account customers. The complaint was filed in the Supreme Court of the State of New York, County of Delaware, on September 12, 2011 and alleges that the Bank engaged in certain unfair practices and failed to make adequate disclosure to customers concerning its overdraft fee assessment practices.  The complaint seeks certification of a class of national checking account holders who have incurred overdraft fees and a subclass of such customers who reside in New York.  In addition, the complaint seeks actual and punitive damages, disgorgement, interest and costs including attorneys' fees.  The Company believes the claims to be without merit and intends to defend the action vigorously.

There are no other material legal proceedings, other than ordinary routine litigation incidental to the business, to which the Company or any of its subsidiaries is a party or of which any of their property is subject.

Item 1A – RISK FACTORS

Management of the Company does not believe there have been any material changes in the risk factors that were disclosed in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2010 filed with the Securities and Exchange Commission on March 1, 2011.

Use of Estimates [Abstract]

Use of Estimates

Note 3.                                Use of Estimates

Preparing financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period, as well as the disclosures provided. Actual results could differ from those estimates. Estimates associated with the allowance for loan and lease losses, other real estate owned ("OREO"), income taxes, pension expense, fair values of financial instruments and status of contingencies are particularly susceptible to material change in the near term.

The allowance for loan and lease losses is the amount which, in the opinion of management, is necessary to absorb probable losses inherent in the loan and lease portfolio. The allowance is determined based upon numerous considerations, including local and national economic conditions, the growth and composition of the loan portfolio with respect to the mix between the various types of loans and their related risk characteristics, a review of the value of collateral supporting the loans, comprehensive reviews of the loan portfolio by the independent loan review staff and management, as well as consideration of volume and trends of delinquencies, nonperforming loans, and loan charge-offs.  As a result of the review of these factors and historical and current indicators, required additions or reductions to the allowance for loan and lease losses are made periodically by charges or credits to the provision for loan and lease losses.

The allowance for loan and lease losses related to impaired loans is based on discounted cash flows using the loan's initial effective interest rate or the fair value of the collateral for certain loans where repayment of the loan is expected to be provided solely by the underlying collateral (collateral dependent loans). The Company's impaired loans are generally collateral dependent loans. The Company considers the estimated cost to sell, on a discounted basis, when determining the fair value of collateral in the measurement of impairment if those costs are expected to reduce the cash flows available to repay or otherwise satisfy the loans.

Management believes that the allowance for loan and lease losses is adequate. While management uses available information to recognize loan and lease losses, future additions or reductions to the allowance for loan and lease losses may be necessary based on changes in economic conditions or changes in the values of properties securing loans in the process of foreclosure. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the Company's allowance for loan and lease losses. Such agencies may require the Company to recognize additions to the allowance for loan and lease losses based on their judgments about information available to them at the time of their examination which may not be currently available to management.  In determining that we will be unable to collect all principal and interest payments due in accordance with the contractual terms of the loan agreements, we consider factors such as payment history and changes in the financial condition of individual borrowers, local economic conditions, historical loss experience and the conditions of the various markets in which the collateral may be liquidated.

OREO consists of properties acquired through foreclosure or by acceptance of a deed in lieu of foreclosure. These assets are recorded at the lower of fair value of the asset acquired less estimated costs to sell or "cost" (cost is defined as the fair value less costs to sell at initial foreclosure). At the time of foreclosure, or when foreclosure occurs in-substance, the excess, if any, of the loan over the fair value of the assets received, less estimated selling costs, is charged to the allowance for loan and lease losses and any subsequent valuation write-downs are charged to other expense. Operating costs associated with the properties are charged to expense as incurred. Gains on the sale of OREO are included in income when title has passed and the sale has met the minimum down payment requirements prescribed by U.S. GAAP.

Income taxes are accounted for under the asset and liability method. The Company files consolidated tax returns on the accrual basis. Deferred income taxes are recognized for the future tax consequences and benefits attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Realization of deferred tax assets is dependent upon the generation of future taxable income or the existence of sufficient taxable income within the available carryback period. A valuation allowance is provided when it is more likely than not that some portion of the deferred tax asset will not be realized. Based on available carrybacks and expected future income, gross deferred tax assets will ultimately be realized and a valuation allowance was not deemed necessary at September 30, 2011 or December 31, 2010. The effect of a change in tax rates on deferred taxes is recognized in income in the period that includes the enactment date.  Uncertain tax positions are recognized only when it is more likely than not (likelihood of greater than 50%), based on technical merits, that the position would be sustained upon examination by taxing authorities.  Tax positions that meet the more than likely than not threshold are measured using a probability-weighted approach as the largest amount of tax benefit that is greater than 50% likely of being realized upon settlement.

Management is required to make various assumptions in valuing its pension assets and liabilities. These assumptions include the expected long-term rate of return on plan assets, the discount rate, and the rate of increase in future compensation levels. Changes to these assumptions could impact earnings in future periods. The Company takes into account the plan asset mix, funding obligations, and expert opinions in determining the various assumptions used to compute pension expense. The Company also considers relevant indices and market interest rates in selecting an appropriate discount rate. A cash flow analysis for expected benefit payments from the plan is performed each year to assist in selecting the discount rate.  In addition, the Company reviews expected inflationary and merit increases to compensation in determining the expected rate of increase in future compensation levels.

Management is required to make various assumptions in determining the fair values of financial instruments.  Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company's entire holdings of a particular financial instrument. Because no market exists for a significant portion of the Company's financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

Management is required to make various assumptions in determining the credit risk involved in issuing contingent obligations such as standby letters of credit, commercial letters of credit, and other lines of credit.  Since commitments to extend credit and unused lines of credit may expire without being fully drawn upon, this amount does not necessarily represent future cash commitments.  Based on historical experience and economic factors, the Company makes estimates of future cash commitments from these contingent obligations to determine their fair value and establish an allowance if necessary.

Note 8.                      Trust Preferred Debentures

CNBF Capital Trust I is a Delaware statutory business trust formed in 1999, for the purpose of issuing $18 million in trust preferred securities and lending the proceeds to the Company. NBT Statutory Trust I is a Delaware statutory business trust formed in 2005, for the purpose of issuing $5 million in trust preferred securities and lending the proceeds to the Company.  NBT Statutory Trust II is a Delaware statutory business trust formed in 2006, for the purpose of issuing $50 million in trust preferred securities and lending the proceeds to the Company to provide funding for the acquisition of CNB Bancorp, Inc. These three statutory business trusts are collectively referred herein to as "the Trusts."  The Company guarantees, on a limited basis, payments of distributions on the trust preferred securities and payments on redemption of the trust preferred securities.  The Trusts are variable interest entities ("VIEs") for which the Company is not the primary beneficiary, as defined by U.S. GAAP.  In accordance with U.S. GAAP, the accounts of the Trusts are not included in the Company's consolidated financial statements.  On January 1, 2010, the Company adopted ASU 2009-17, Consolidations: Improvements to Financial Reporting by Enterprises Involved with Variable Interest Entities ("Topic 810"), which had no impact on the Company's financial statements.

As of September 30, 2011, the Trusts had the following issues of trust preferred debentures, all held by the Trusts, outstanding (dollars in thousands):

Allowance for Loan and Lease Losses and Credit Quality of Loans and Leases

Note  5.                      Allowance for Loan and Lease Losses and Credit Quality of Loans and Leases

Allowance for Loan and Lease Losses

The allowance for loan and lease losses is maintained at a level estimated by management to provide adequately for risk of probable losses inherent in the current loan and lease portfolio. The adequacy of the allowance for loan and lease losses is continuously monitored.  It is assessed for adequacy using a methodology designed to ensure the level of the allowance reasonably reflects the loan and lease portfolio's risk profile. It is evaluated to ensure that it is sufficient to absorb all reasonably estimable credit losses inherent in the current loan and lease portfolio.

To develop and document a systematic methodology for determining the allowance for loan and lease losses, the Company has divided the loan portfolio into three portfolio segments, each with different risk characteristics and methodologies for assessing risk.  Each portfolio segment is broken down into class segments where appropriate.  Class segments contain unique measurement attributes, risk characteristics and methods for monitoring and assessing risk that are necessary to develop the allowance for loan and lease losses.  Unique characteristics such as borrower type, loan type, collateral type, and risk characteristics define each class segment.  The following table illustrates the portfolio and class segments for the Company's loan portfolio:

Portfolio	Class
Commercial Loans	Commercial
	Commercial Real Estate
	Agricultural
	Agricultural Real Estate
	Business Banking
Consumer Loans	Indirect
	Home Equity
	Direct
Residential Real Estate Mortgages

Commercial - The Company offers a variety of loan options to meet the specific needs of our commercial customers including term loans, time notes and lines of credit.  Such loans are made available to businesses for working capital such as inventory and receivables, business expansion and equipment purchases. Generally, a collateral lien is placed on equipment or other assets owned by the borrower.  These loans carry a higher risk than commercial real estate loans due to the nature of the underlying collateral, which can be business assets such as equipment and accounts receivable and is generally less liquid than real estate. To reduce the risk, management also attempts to secure real estate as collateral and obtain personal guarantees of the borrowers.

Commercial Real Estate - The Company offers commercial real estate loans to finance real estate purchases, refinancings, expansions and improvements to commercial properties.  Commercial real estate loans are made to finance the purchases of real property which generally consists of real estate with completed structures. These commercial real estate loans are secured by first liens on the real estate, which may include apartments, commercial structures, housing businesses, healthcare facilities, and other non owner-occupied facilities.  These loans are typically less risky than commercial loans, since they are secured by real estate and buildings. The Company's underwriting analysis includes credit verification, independent appraisals, a review of the borrower's financial condition, and a detailed analysis of the borrower's underlying cash flows. These loans are typically originated in amounts of no more than 80% of the appraised value of the property.

Agricultural - The Company offers a variety of agricultural loans to meet the needs of our agricultural customers including term loans, time notes, and lines of credit.  These loans are made to purchase livestock, purchase and modernize equipment, and finance seasonal crop expenses.  Generally, a collateral lien is placed on the livestock, equipment, produce inventories, and/or receivables owned by the borrower.  These loans may carry a higher risk than commercial and agricultural real estate loans due to the industry price volatility, and in some cases, the perishable nature of the underlying collateral.  To reduce these risks, management may attempt to secure these loans with additional real estate collateral, obtain personal guarantees of the borrowers, or obtain government loan guarantees to provide further support.

Agricultural Real Estate - The Company offers real estate loans to our agricultural customers to finance farm related real estate purchases, refinancings, expansions, and improvements to agricultural properties such as barns, production facilities, and land.  The agricultural real estate loans are secured by first liens on the farm real estate.  Because they are secured by land and buildings, these loans may be less risky than agricultural loans.  The Company's underwriting analysis includes credit verification, independent appraisals, a review of the borrower's financial condition, and a detailed analysis of the borrower's underlying cash flows.  These loans are typically originated in amounts of no more than 75% of the appraised value of the property.  Government loan guarantees may be obtained to provide further support.

Business Banking - The Company offers a variety of loan options to meet the specific needs of our small business customers including term loans, small business mortgages and lines of credit.  Such loans are generally less than $350 thousand and are made available to businesses for working capital such as inventory and receivables, business expansion, equipment purchases, and agricultural needs.  Generally, a collateral lien is placed on equipment or other assets owned by the borrower such as inventory and/or receivables.  These loans carry a higher risk than commercial loans due to the smaller size of the borrower and lower levels of capital.  To reduce the risk, the Company obtains personal guarantees of the owners for a majority of the loans.

Indirect - The Company maintains relationships with many dealers primarily in the communities that we serve.  Through these relationships, the company finances the purchases of automobiles and recreational vehicles (such as campers, boats, etc.) indirectly through dealer relationships.  Approximately 70% of the indirect relationships represent automobile financing.  Most of these loans carry a fixed rate of interest with principal repayment terms typically ranging from three to six years, based upon the nature of the collateral and the size of the loan. The majority of indirect consumer loans are underwritten on a secured basis using the underlying collateral being financed.

Home Equity -The Company offers fixed home equity loans as well as home equity lines of credit to consumers to finance home improvements, debt consolidation, education and other uses.  Consumers are able to borrow up to 85% of the equity in their homes.  The Company originates home equity lines of credit and second mortgage loans (loans secured by a second [junior] lien position on one-to-four-family residential real estate).  These loans carry a higher risk than first mortgage residential loans as they are in a second position with respect to collateral.  Risk is reduced through underwriting criteria, which include credit verification, appraisals, a review of the borrower's financial condition, and personal cash flows.  A security interest, with title insurance when necessary, is taken in the underlying real estate.

Direct - The Company offers a variety of consumer installment loans to finance vehicle purchases, mobile home purchases and personal expenditures.  Most of these loans carry a fixed rate of interest with principal repayment terms typically ranging from one to ten years, based upon the nature of the collateral and the size of the loan. The majority of consumer loans are underwritten on a secured basis using the underlying collateral being financed or a customer's deposit account. In addition to installment loans, the Company also offers personal lines of credit and overdraft protection.  A minimal amount of loans are unsecured, which carry a higher risk of loss.

Residential Real Estate - Residential real estate loans consist primarily of loans secured by first or second deeds of trust on primary residences.  We originate adjustable-rate and fixed-rate, one-to-four-family residential real estate loans for the construction, purchase or refinancing of a mortgage.  These loans are collateralized by owner-occupied properties located in the Company's market area. When market conditions are favorable, for longer term, fixed-rate residential mortgages without escrow, the Company retains the servicing, but sells the right to receive principal and interest to Freddie Mac.   This practice allows the Company to manage interest rate risk, liquidity risk, and credit risk.  Loans on one-to-four-family residential real estate are generally originated in amounts of no more than 85% of the purchase price or appraised value (whichever is lower), or have private mortgage insurance.  Mortgage title insurance and hazard insurance are normally required. Construction loans have a unique risk, because they are secured by an incomplete dwelling. This risk is reduced through periodic site inspections, including one at each loan draw period.

Allowance for Loan and Lease Loss Calculation

Management considers the accounting policy related to the allowance for loan and lease losses to be a critical accounting policy given the inherent uncertainty in evaluating the levels of the allowance required to cover credit losses in the portfolio and the material effect that such judgments can have on the consolidated results of operations.

For purposes of evaluating the adequacy of the allowance, the Company considers a number of significant factors that affect the collectibility of the portfolio.  For individually analyzed loans, these include estimates of loss exposure, which reflect the facts and circumstances that affect the likelihood of repayment of such loans as of the evaluation date. For homogeneous pools of loans and leases, estimates of the Company's exposure to credit loss reflect a current assessment of a number of factors, which could affect collectibility.  These factors include:  past loss experience;  size, trend, composition, and nature of loans;  changes in lending policies and procedures, including underwriting standards and collection,  charge-offs  and  recoveries; trends experienced in nonperforming and delinquent loans; current economic conditions in the Company's market;  portfolio concentrations that may affect loss experienced across one or more components of the portfolio; the effect of external factors such as competition, legal and regulatory requirements; and the experience, ability, and depth of lending management and staff. In addition, various regulatory agencies, as an integral component of their examination process, periodically review the Company's allowance for loan and lease losses.  Such agencies may require the Company to make loan grade changes as well as recognize additions to the allowance based on their examinations.

After a thorough consideration of the factors discussed above, any required additions or reductions to the allowance for loan and lease losses are made periodically by charges or credits to the provision for loan and lease losses. These charges or credits are necessary to maintain the allowance at a level which management believes is reasonably reflective of overall inherent risk of probable loss in the portfolio. While management uses available information to recognize losses on loans and leases, additions and reductions of the allowance may fluctuate from one reporting period to another.  These fluctuations are reflective of changes in risk associated with portfolio content and/or changes in management's assessment of any or all of the determining factors discussed above.  The following table illustrates the changes in the allowance for loan and lease losses by portfolio segment for the three and nine months ended September 30, 2011 and September 30, 2010:

Credit Quality of Loans and Leases

Loans and leases are placed on nonaccrual status when timely collection of principal and interest in accordance with contractual terms is doubtful. Loans and leases are transferred to nonaccrual status generally when principal or interest payments become ninety days delinquent, unless the loan is well secured and in the process of collection, or sooner when management concludes or circumstances indicate that borrowers may be unable to meet contractual principal or interest payments.  When a loan or lease is transferred to a nonaccrual status, all interest previously accrued in the current period but not collected is reversed against interest income in that period. Interest accrued in a prior period and not collected is charged-off against the allowance for loan and lease losses.  The Company's nonaccrual policies are the same for all classes of financing receivable.

If ultimate repayment of a nonaccrual loan is expected, any payments received are applied in accordance with contractual terms. If ultimate repayment of principal is not expected, any payment received on a nonaccrual loan is applied to principal until ultimate repayment becomes expected.  Nonaccrual loans are returned to accrual status when they become current as to principal and interest and demonstrate a period of performance under the contractual terms and, in the opinion of management, are fully collectible as to principal and interest.  When in the opinion of management the collection of principal appears unlikely, the loan balance is charged-off in total or in part.  For loans in all portfolios, the principal amount is charged off in full or in part as soon as management determines, based on available facts, that the collection of principal in full is improbable.  For commercial loans, management considers specific facts and circumstances relative to individual credits in making such a determination.  For consumer and residential loan classes, management uses specific guidance and thresholds from the Federal Financial Institutions Examination Council's Uniform Retail Credit Classification and Account Management Policy.

There were no material commitments to extend further credit to borrowers with nonperforming loans. Within nonaccrual loans, there were approximately $4.6 million and $1.0 million of troubled debt restructured loans at September 30, 2011 and December 31, 2010, respectively.

Impaired loans, which primarily consist of nonaccruing commercial, commercial real estate, agricultural, agricultural real estate and business banking loans, as well as certain consumer loans that have been modified in a troubled debt restructuring were $23.7 million at September 30, 2011 and $25.4 million at December 31, 2010.

The methodology used to establish the allowance for loan and lease losses on impaired loans incorporates specific allocations on loans analyzed individually.  Classified loans with outstanding balances of $500 thousand or more are evaluated for impairment through the Company's quarterly status review process.  In determining that we will be unable to collect all principal and interest payments due in accordance with the contractual terms of the loan agreements, we consider factors such as payment history and changes in the financial condition of individual borrowers, local economic conditions, historical loss experience and the conditions of the various markets in which the collateral may be liquidated.  For loans that are evaluated for impairment, impairment is measured by one of three methods: 1) the fair value of collateral less cost to sell, 2) present value of expected future cash flows or 3) the loan's observable market price.  These impaired loans are reviewed on a quarterly basis for changes in the measurement of impairment.  For impaired loans measured using the present value of expected cash flow method, any change to the previously recognized impairment loss is recognized as a change to the allowance account and recorded in the consolidated statement of income as a component of the provision for credit losses.  At September 30, 2011, $0.5 million of the total impaired loans had a specific reserve allocation of $0.2 million compared to $5.7 million of impaired loans at December 31, 2010 which had a specific reserve allocation of $2.2 million.

The following table provides additional information on impaired loans and specific reserve allocations as of September 30, 2011 and December 31, 2010:

There has been significant disruption and volatility in the financial and capital markets since the second half of 2008.  Turmoil in the mortgage industry adversely impacted both domestic and global economies and led to a significant credit and liquidity crisis in many domestic markets.  These conditions were attributable to a variety of factors, in particular the fallout associated with subprime mortgage loans (a type of lending we have never actively pursued).  The disruption was exacerbated by the decline of the real estate and housing market.  However, in the markets in which the Company does business, the disruption has been somewhat delayed and less significant than in the national market.  For example, our real estate market has not suffered the extreme declines seen nationally and our unemployment rate, while notably higher than in prior periods, is still below the national average.

While we continue to adhere to prudent underwriting standards, as a lender we may be adversely impacted by general economic weaknesses and, in particular, a sharp downturn in the housing market nationally.  Decreases in real estate values could adversely affect the value of property used as collateral for our loans.  Adverse changes in the economy may have a negative effect on the ability of our borrowers to make timely loan payments, which would have an adverse impact on our earnings.  An adverse impact on loan delinquencies would decrease our net interest income and adversely impact our loan loss experience, causing increases in our provision and allowance for loan and lease losses.

The Company has developed an internal loan grading system to evaluate and quantify the Bank's loan portfolio with respect to quality and risk.  The system focuses on, among other things, financial strength of borrowers, experience and depth of borrower's management, primary and secondary sources of repayment, payment history, nature of the business, and outlook on particular industries.  The internal grading system enables the Company to monitor the quality of the entire loan portfolio on a consistent basis and provide management with an early warning system, enabling recognition and response to problem loans and potential problem loans.

Commercial Grading System

For commercial and agricultural loans, the Company uses a grading system that relies on quantifiable and measurable characteristics when available.  This would include comparison of financial strength to available industry averages, comparison of transaction factors (loan terms and conditions) to loan policy, and comparison of credit history to stated repayment terms and industry averages. Some grading factors are necessarily more subjective such as economic and industry factors, regulatory environment, and management.  Classified commercial loans consist of loans graded substandard and below.  All classified loans with outstanding balances of $500 thousand or more are evaluated individually for impairment through the quarterly review process.  The grading system for commercial and agricultural loans is as follows:

Doubtful

A doubtful loan has a high probability of total or substantial loss, but because of specific pending events that may strengthen the asset, its classification as a loss is deferred. Doubtful borrowers are usually in default, lack adequate liquidity or capital, and lack the resources necessary to remain an operating entity. Pending events can include mergers, acquisitions, liquidations, capital injections, the perfection of liens on additional collateral, the valuation of collateral, and refinancing. Generally, pending events should be resolved within a relatively short period and the ratings will be adjusted based on the new information. Nonaccrual treatment is required for doubtful assets because of the high probability of loss.

Substandard

Substandard loans have a high probability of payment default, or they have other well-defined weaknesses. They require more intensive supervision by bank management. Substandard loans are generally characterized by current or expected unprofitable operations, inadequate debt service coverage, inadequate liquidity, or marginal capitalization. Repayment may depend on collateral or other credit risk mitigants. For some Substandard loans, the likelihood of full collection of interest and principal may be in doubt and should be placed on nonaccrual. Although Substandard assets in the aggregate will have a distinct potential for loss, an individual asset's loss potential does not have to be distinct for the asset to be rated Substandard.

Special Mention

Special Mention loans have potential weaknesses that may, if not checked or corrected, weaken the asset or inadequately protect the Company's position at some future date. These loans pose elevated risk, but their weakness does not yet justify a Substandard classification. Borrowers may be experiencing adverse operating trends (declining revenues or margins) or may be struggling with an ill-proportioned balance sheet (e.g., increasing inventory without an increase in sales, high leverage, tight liquidity). Adverse economic or market conditions, such as interest rate increases or the entry of a new competitor, may also support a Special Mention rating. Although a Special Mention loan has a higher probability of default than a pass asset, its default is not imminent.

Pass

Loans graded as Pass encompass all loans not graded as Doubtful, Substandard, or Special Mention.  Pass loans are in compliance with loan covenants, and payments are generally made as agreed.  Pass loans range from superior quality to fair quality.

Business Banking Grading System

Business Banking loans are graded as either Classified or Non-classified:

Classified

Classified loans are inadequately protected by the current worth and paying capacity of the obligor or, if applicable, the collateral pledged.   These loans have a well-defined weakness, or weaknesses, that jeopardize the liquidation of the debt, or in some cases make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected.   Classified loans have a high probability of payment default, or a high probability of total or substantial loss.  These loans require more intensive supervision by management and are generally characterized by current or expected unprofitable operations, inadequate debt service coverage, inadequate liquidity, or marginal capitalization.  Repayment may depend on collateral or other credit risk mitigants.  When the likelihood of full collection of interest and principal may be in doubt; classified loans are considered to have a nonaccrual status.   In some cases, Classified loans are considered uncollectible and of such little value that their continuance as assets is not warranted.

Non-classified

Loans graded as Non-classified encompass all loans not graded as Classified.  Non-classified loans are in compliance with loan covenants, and payments are generally made as agreed.

Consumer and Residential Mortgage Grading System

Consumer and Residential Mortgage loans are graded as either Performing or Nonperforming.   Nonperforming loans are loans that are 1) over 90 days past due and interest is still accruing, 2) on nonaccrual status or 3) restructured.  All loans not meeting any of these three criteria are considered Performing.

Modifications

The Company's loan portfolio includes certain loans that have been modified in a TDR, where economic concessions have been granted to borrowers who have experienced or are expected to experience financial difficulties.  These concessions typically result from the Company's loss mitigation activities and could include reductions in the interest rate, payment extensions, forgiveness of principal, forbearance or other actions.  Certain TDRs are classified as nonperforming at the time of restructure and may only be returned to performing status after considering the borrower's sustained repayment performance for a reasonable period, generally six months.

When the Company modifies a loan, management evaluates any possible impairment based on the present value of the expected future cash flows, discounted at the contractual interest rate of the original loan agreement, except when the sole (remaining) source of repayment for the loan is the operation or liquidation of the collateral.  In these cases, management uses the current fair value of the collateral, less selling costs, instead of discounted cash flows.  If management determines that the value of the modified loan is less than the recorded investment in the loan (net of previous charge-offs, deferred loan fees or costs and unamortized premium or discount), impairment is recognized by segment or class of loan as applicable, through an allowance estimate or a charge-off to the allowance.  Segment and class status is determined by the loan's classification at origination.

Modifications made during the three month period ending September 30, 2011 consisted of three commercial loans totaling $0.7 million.   Modifications during the nine month period ending September 30, 2011 consisted of twenty-five home equity modifications totaling $2.4 million and four residential real estate mortgages totaling $0.8 million, in addition to the three aforementioned commercial loan modifications.  For all such modifications, the pre and post outstanding recorded investment amount remained unchanged.  During the three month period ending September 30, 2011 there were no subsequent defaults on previously modified loans.  During the nine months ended September 30, 2011, there were six home equity loans classified as TDRs totaling $0.6 million and two residential real estate loans classified as TDRs totaling $0.4 million that subsequently defaulted on their renegotiated terms.

As a result of adopting the amendments in Accounting Standards Update ("ASU") No. 2011-02, "A Creditor's Determination of Whether a Restructuring Is a Troubled Debt Restructuring (Topic 310)", the Company reassessed all restructurings that occurred on or after the beginning of the current fiscal year (January 1, 2011) for identification as TDRs.  The Company identified as TDRs certain receivables for which the allowance for credit losses had previously been measured under a general allowance for credit losses methodology.  Upon identifying those receivables as TDRs, the Company identified them as impaired under the guidance in Section 310-10-35 and evaluated TDRs for impairment in accordance with the Company's methodology used to establish the allowance for loan and lease losses on impaired loans. The amendments in ASU No. 2011-02 require prospective application of the impairment measurement guidance in Section 310-10-35 for those receivables newly identified as impaired.  Adoption of this amendment had no material impact on the Company's measured of impairment on these loans.

Declines in the fair value of held-to-maturity and available-for-sale securities below their cost that are deemed to be other than temporary are reflected in earnings as realized losses or in other comprehensive income, depending on whether the Company intends to sell the security or more likely than not will be required to sell the security before recovery of its amortized cost basis less any current-period credit loss.  If the Company intends to sell the security or more likely than not will be required to sell the security before recovery of its amortized cost basis less any current-period credit loss, the other-than-temporary impairment shall be recognized in earnings equal to the entire difference between the investment’s amortized cost basis and its fair value at the balance sheet date.  If the Company does not intend to sell the security and it is not more likely than not that the entity will be required to sell the security before recovery of its amortized cost basis less any current-period credit loss, the other-than-temporary impairment shall be separated into (a) the amount representing the credit loss and (b) the amount related to all other factors.  The amount of the total other-than-temporary impairment related to the credit loss shall be recognized in earnings. The amount of the total other-than-temporary impairment related to other factors shall be recognized in other comprehensive income, net of applicable taxes.

In estimating other-than-temporary impairment losses, management considers, among other things, (i) the length of time and the extent to which the fair value has been less than cost, (ii) the financial condition and near-term prospects of the issuer, and (iii) the historical and implied volatility of the fair value of the security.

Management has the intent to hold the securities classified as held to maturity until they mature, at which time it is believed the Company will receive full value for the securities. Furthermore, as of September 30, 2011, management also had the intent to hold, and will not be required to sell, the securities classified as available for sale for a period of time sufficient for a recovery of cost, which may be until maturity.  The unrealized losses are due to increases in market interest rates over the yields available at the time the underlying securities were purchased. When necessary, the Company has performed a discounted cash flow analysis to determine whether or not it will receive the contractual principal and interest on certain securities.  The fair value is expected to recover as the bonds approach their maturity date or repricing date or if market yields for such investments decline.  As of September 30, 2011, management believes the impairments detailed in the table above are temporary and no other-than-temporary impairment losses have been realized in the Company’s consolidated statements of income.

The following tables set forth information with regard to contractual maturities of debt securities at September 30, 2011:

Maturities of mortgage-backed, collateralized mortgage obligations and asset-backed securities are stated based on their estimated average lives.  Actual maturities may differ from estimated average lives or contractual maturities because, in certain cases, borrowers have the right to call or prepay obligations with or without call or prepayment penalties.

Except for U.S. Government related securities, there were no holdings, when taken in the aggregate, of any single issuer that exceeded 10% of consolidated stockholders’ equity at September 30, 2011

Earnings Per Share [Abstract]

Earnings Per Share

Note 6.                      Earnings Per Share

Basic earnings per share excludes dilution and is computed by dividing income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity (such as the Company's dilutive stock options and restricted stock units).

The following is a reconciliation of basic and diluted earnings per share for the periods presented in the consolidated statements of income.

Commitments And Contingencies [Abstract]

Commitments and Contingent Liabilities

Note 4.                                Commitments and Contingencies

The Company is a party to financial instruments in the normal course of business to meet the financing needs of its customers and to reduce its own exposure to fluctuating interest rates. These financial instruments include commitments to extend credit, unused lines of credit, and standby letters of credit. Exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to make loans and standby letters of credit is represented by the contractual amount of those instruments. The Company uses the same credit origination guidelines, portfolio maintenance and management procedures as other credit and off-balance sheet products.  Commitments to extend credit and unused lines of credit totaled $749.2 million at September 30, 2011 and $643.6 million at December 31, 2010.  Since commitments to extend credit and unused lines of credit may expire without being fully drawn upon, this amount does not necessarily represent future cash commitments. Collateral obtained upon exercise of the commitment is determined using management's credit evaluation of the borrower and may include accounts receivable, inventory, property, land and other items.

The Company guarantees the obligations or performance of customers by issuing standby letters of credit to third parties. These standby letters of credit are frequently issued in support of third party debt, such as corporate debt issuances, industrial revenue bonds and municipal securities. The credit risk involved in issuing standby letters of credit is essentially the same as the credit risk involved in extending loan facilities to customers, and they are subject to the same credit origination guidelines, portfolio maintenance and management procedures as other credit and off-balance sheet products. Typically, these instruments have terms of five years or less and expire unused; therefore, the total amounts do not necessarily represent future cash commitments. Standby letters of credit totaled $26.0 million at September 30, 2011 and $26.2 million at December 31, 2010. As of September 30, 2011, the fair value of standby letters of credit was not significant to the Company's consolidated financial statements.

The Company has also entered into commercial letter of credit agreements on behalf of its customers.  Under these agreements, the Company, on the request of its customer, opens the letter of credit and makes a commitment to honor draws made under the agreement, whereby the beneficiary is normally the provider of goods and/or services and the Company essentially replaces the customer as the payee.  The credit risk involved in issuing commercial letters of credit is essentially the same as the credit risk involved in extending loan facilities to customers, and they are subject to the same credit origination guidelines, portfolio maintenance and management procedures as other credit and off-balance sheet products.  Typically, these agreements vary in terms and the total amounts do not necessarily represent future cash commitments.  Commercial letters of credit totaled $15.7 million at September 30, 2011 and $16.3 million at December 31, 2010.  As of September 30, 2011, the fair value of commercial letters of credit was not significant to the Company's consolidated financial statements.

Fair Values of Financial Instruments

Fair Values of Financial Instruments [Abstract]

Fair Values of Financial Instruments

Note 9.    Fair Value Measurements and Fair Value of Financial Instruments

U.S. GAAP states that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants.  Fair value measurements are not adjusted for transaction costs.  A fair value hierarchy exists within U.S. GAAP that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1 measurements) and the lowest priority to unobservable inputs (level 3 measurements). The three levels of the fair value hierarchy are described below:

Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

Level 2 -  Quoted prices for similar assets or liabilities in active markets, quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability;

Level 3 - Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity).

A financial instrument's level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.

The types of instruments valued based on quoted market prices in active markets include most U.S. government and agency securities, many other sovereign government obligations, liquid mortgage products, active listed equities and most money market securities. Such instruments are generally classified within level 1 or level 2 of the fair value hierarchy.  The Company does not adjust the quoted price for such instruments.

The types of instruments valued based on quoted prices in markets that are not active, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency include most investment-grade and high-yield corporate bonds, less liquid mortgage products, less liquid agency securities, less liquid listed equities, state, municipal and provincial obligations, and certain physical commodities. Such instruments are generally classified within level 2 of the fair value hierarchy.

Level 3 is for positions that are not traded in active markets or are subject to transfer restrictions, valuations are adjusted to reflect illiquidity and/or non-transferability, and such adjustments are generally based on available market evidence. In the absence of such evidence, management's best estimate will be used. Management's best estimate consists of both internal and external support on certain Level 3 investments. Subsequent to inception, management only changes level 3 inputs and assumptions when corroborated by evidence such as transactions in similar instruments, completed or pending third-party transactions in the underlying investment or comparable entities, subsequent rounds of financing, recapitalizations and other transactions across the capital structure, offerings in the equity or debt markets, and changes in financial ratios or cash flows.

For the nine months ended September 30, 2011, the Company has made no transfers of assets between Level 1 and Level 2, and has had no Level 3 activity.

The following tables set forth the Company's financial assets and liabilities measured on a recurring basis that were accounted for at fair value.  Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement (in thousands):

Certain common equity securities are reported at fair value utilizing Level 1 inputs (exchange quoted prices).  The majority of the other investment securities are reported at fair value utilizing Level 2 inputs.  The prices for these instruments are obtained through an independent pricing service or dealer market participants with whom the Company has historically transacted both purchases and sales of investment securities.  Prices obtained from these sources include prices derived from market quotations and matrix pricing.  The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond's terms and conditions, among other things.  Management reviews the methodologies used in pricing the securities by its third party providers.

U.S. GAAP requires disclosure of assets and liabilities measured and recorded at fair value on a nonrecurring basis such as goodwill, loans held for sale, other real estate owned, lease residuals, collateral-dependent impaired loans, mortgage servicing rights, and held-to-maturity securities.  The only nonrecurring fair value measurement recorded during the nine month period ended September 30, 2011 was related to impaired loans.  During the nine month period ended September 30, 2011, the Company did not establish additional specific reserves on impaired loans.  The Company uses the fair value of underlying collateral, less costs to sell, to estimate the specific reserves for collateral dependent impaired loans.  Based on the valuation techniques used, the fair value measurements for collateral dependent impaired loans are classified as Level 3.

The following table sets forth information with regard to estimated fair values of financial instruments at September 30, 2011 and December 31, 2010:

These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company's entire holdings of a particular financial instrument. Because no market exists for a significant portion of the Company's financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

Fair value estimates are based on existing on and off balance sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. For example, the Company has a substantial trust and investment management operation that contributes net fee income annually. The trust and investment management operation is not considered a financial instrument, and its value has not been incorporated into the fair value estimates. Other significant assets and liabilities include the benefits resulting from the low-cost funding of deposit liabilities as compared to the cost of borrowing funds in the market, and premises and equipment. In addition, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in the estimate of fair value.

Employee Benefit Plans [Abstract]

Employee Benefit Plans

Note 7.                       Defined Benefit Postretirement Plans

The Company has a qualified, noncontributory, defined benefit pension plan covering substantially all of its employees at September 30, 2011.  Benefits paid from the plan are based on age, years of service, compensation and social security benefits, and are determined in accordance with defined formulas. The Company's policy is to fund the pension plan in accordance with Employee Retirement Income Security Act ("ERISA") standards. Assets of the plan are invested in publicly traded stocks and bonds and mutual funds. Prior to January 1, 2000, the Company's plan was a traditional defined benefit plan based on final average compensation.  On January 1, 2000, the plan was converted to a cash balance plan with grandfathering provisions for existing participants.

In addition to the pension plan, the Company also provides supplemental employee retirement plans to certain current and former executives.  These supplemental employee retirement plans and the defined benefit pension plan are collectively referred to herein as "Pension Benefits."

Also, the Company provides certain health care benefits for retired employees.  Benefits are accrued over the employees' active service period. Only employees that were employed by the Company on or before January 1, 2000 are eligible to receive postretirement health care benefits.  The plan is contributory for participating retirees, requiring participants to absorb certain deductibles and coinsurance amounts with contributions adjusted annually to reflect cost sharing provisions and benefit limitations called for in the plan.  Eligibility is contingent upon the direct transition from active employment status to retirement without any break in employment from the Company.  Employees also must be participants in the Company's medical plan prior to their retirement.  The Company funds the cost of postretirement health care as benefits are paid. The Company elected to recognize the transition obligation on a delayed basis over twenty years.  These postretirement benefits are referred to herein as "Other Benefits."

The components of expense for Pension Benefits and Other Benefits are set forth below (in thousands):

Total cost (benefit)	$               103	$            336	$             213	$               182

The Company is not required to make contributions to the plans in 2011, and did not do so during the nine months ended September 30, 2011.  The Company recorded approximately $0.3 million and $0.7 million, net of tax, as amortization of pension amounts previously recognized in Accumulated Other Comprehensive Income during the three and nine months ended September 30, 2011, respectively.

Market conditions can result in an unusually high degree of volatility and increase the risks and short term liquidity associated with certain investments held by the Company's defined benefit pension plan ("the Plan") which could impact the value of these investments.

Use of Estimates (Policies)

Use of Estimates [Abstract]

Use of Estimates

Preparing financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period, as well as the disclosures provided. Actual results could differ from those estimates. Estimates associated with the allowance for loan and lease losses, other real estate owned ("OREO"), income taxes, pension expense, fair values of financial instruments and status of contingencies are particularly susceptible to material change in the near term.

The allowance for loan and lease losses is the amount which, in the opinion of management, is necessary to absorb probable losses inherent in the loan and lease portfolio. The allowance is determined based upon numerous considerations, including local and national economic conditions, the growth and composition of the loan portfolio with respect to the mix between the various types of loans and their related risk characteristics, a review of the value of collateral supporting the loans, comprehensive reviews of the loan portfolio by the independent loan review staff and management, as well as consideration of volume and trends of delinquencies, nonperforming loans, and loan charge-offs.  As a result of the review of these factors and historical and current indicators, required additions or reductions to the allowance for loan and lease losses are made periodically by charges or credits to the provision for loan and lease losses.

The allowance for loan and lease losses related to impaired loans is based on discounted cash flows using the loan's initial effective interest rate or the fair value of the collateral for certain loans where repayment of the loan is expected to be provided solely by the underlying collateral (collateral dependent loans). The Company's impaired loans are generally collateral dependent loans. The Company considers the estimated cost to sell, on a discounted basis, when determining the fair value of collateral in the measurement of impairment if those costs are expected to reduce the cash flows available to repay or otherwise satisfy the loans.

Management believes that the allowance for loan and lease losses is adequate. While management uses available information to recognize loan and lease losses, future additions or reductions to the allowance for loan and lease losses may be necessary based on changes in economic conditions or changes in the values of properties securing loans in the process of foreclosure. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the Company's allowance for loan and lease losses. Such agencies may require the Company to recognize additions to the allowance for loan and lease losses based on their judgments about information available to them at the time of their examination which may not be currently available to management.  In determining that we will be unable to collect all principal and interest payments due in accordance with the contractual terms of the loan agreements, we consider factors such as payment history and changes in the financial condition of individual borrowers, local economic conditions, historical loss experience and the conditions of the various markets in which the collateral may be liquidated.

OREO consists of properties acquired through foreclosure or by acceptance of a deed in lieu of foreclosure. These assets are recorded at the lower of fair value of the asset acquired less estimated costs to sell or "cost" (cost is defined as the fair value less costs to sell at initial foreclosure). At the time of foreclosure, or when foreclosure occurs in-substance, the excess, if any, of the loan over the fair value of the assets received, less estimated selling costs, is charged to the allowance for loan and lease losses and any subsequent valuation write-downs are charged to other expense. Operating costs associated with the properties are charged to expense as incurred. Gains on the sale of OREO are included in income when title has passed and the sale has met the minimum down payment requirements prescribed by U.S. GAAP.

Income taxes are accounted for under the asset and liability method. The Company files consolidated tax returns on the accrual basis. Deferred income taxes are recognized for the future tax consequences and benefits attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Realization of deferred tax assets is dependent upon the generation of future taxable income or the existence of sufficient taxable income within the available carryback period. A valuation allowance is provided when it is more likely than not that some portion of the deferred tax asset will not be realized. Based on available carrybacks and expected future income, gross deferred tax assets will ultimately be realized and a valuation allowance was not deemed necessary at September 30, 2011 or December 31, 2010. The effect of a change in tax rates on deferred taxes is recognized in income in the period that includes the enactment date.  Uncertain tax positions are recognized only when it is more likely than not (likelihood of greater than 50%), based on technical merits, that the position would be sustained upon examination by taxing authorities.  Tax positions that meet the more than likely than not threshold are measured using a probability-weighted approach as the largest amount of tax benefit that is greater than 50% likely of being realized upon settlement.

Management is required to make various assumptions in valuing its pension assets and liabilities. These assumptions include the expected long-term rate of return on plan assets, the discount rate, and the rate of increase in future compensation levels. Changes to these assumptions could impact earnings in future periods. The Company takes into account the plan asset mix, funding obligations, and expert opinions in determining the various assumptions used to compute pension expense. The Company also considers relevant indices and market interest rates in selecting an appropriate discount rate. A cash flow analysis for expected benefit payments from the plan is performed each year to assist in selecting the discount rate.  In addition, the Company reviews expected inflationary and merit increases to compensation in determining the expected rate of increase in future compensation levels.

Management is required to make various assumptions in determining the fair values of financial instruments.  Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company's entire holdings of a particular financial instrument. Because no market exists for a significant portion of the Company's financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

Management is required to make various assumptions in determining the credit risk involved in issuing contingent obligations such as standby letters of credit, commercial letters of credit, and other lines of credit.  Since commitments to extend credit and unused lines of credit may expire without being fully drawn upon, this amount does not necessarily represent future cash commitments.  Based on historical experience and economic factors, the Company makes estimates of future cash commitments from these contingent obligations to determine their fair value and establish an allowance if necessary.

Income Tax Uncertainties Policy

Income taxes are accounted for under the asset and liability method. The Company files consolidated tax returns on the accrual basis. Deferred income taxes are recognized for the future tax consequences and benefits attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Realization of deferred tax assets is dependent upon the generation of future taxable income or the existence of sufficient taxable income within the available carryback period. A valuation allowance is provided when it is more likely than not that some portion of the deferred tax asset will not be realized. Based on available carrybacks and expected future income, gross deferred tax assets will ultimately be realized and a valuation allowance was not deemed necessary at September 30, 2011 or December 31, 2010. The effect of a change in tax rates on deferred taxes is recognized in income in the period that includes the enactment date.  Uncertain tax positions are recognized only when it is more likely than not (likelihood of greater than 50%), based on technical merits, that the position would be sustained upon examination by taxing authorities.  Tax positions that meet the more than likely than not threshold are measured using a probability-weighted approach as the largest amount of tax benefit that is greater than 50% likely of being realized upon settlement.

Pension Plans Policy

Management is required to make various assumptions in valuing its pension assets and liabilities. These assumptions include the expected long-term rate of return on plan assets, the discount rate, and the rate of increase in future compensation levels. Changes to these assumptions could impact earnings in future periods. The Company takes into account the plan asset mix, funding obligations, and expert opinions in determining the various assumptions used to compute pension expense. The Company also considers relevant indices and market interest rates in selecting an appropriate discount rate. A cash flow analysis for expected benefit payments from the plan is performed each year to assist in selecting the discount rate.  In addition, the Company reviews expected inflationary and merit increases to compensation in determining the expected rate of increase in future compensation levels.
