Report of Independent Registered Public Accounting Firm June 26, 2007 To the Participants and Administrators of Community Bank System, Inc. 401(k) Employee Stock Ownership Plan We have audited the accompanying statements of net assets available for benefits of Community Bank System, Inc. 401(k) Employee Stock Ownership Plan ("the Plan") as of December 31, 2006 and 2005 and the related statements of changes in net assets available for benefits for the years then ended. These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Plan is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Plan's internal control over financial reporting. Accordingly, we express no such opinion. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2006 and 2005, and the changes in net assets available for benefits for the years then ended in conformity with generally accepted accounting principles (United States). Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental Schedule of Assets Held for Investment Purposes at End of Year as of December 31, 2006, is presented for the purpose of additional analysis and is not a required part of the basic financial statements, but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This supplemental schedule is the responsibility of the Plan's management. The supplemental schedule has been subjected to the auditing procedures applied in the audit of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole. /s/ Dannible & McKee, LLP Dannible & McKee, LLP Syracuse, New York Community Bank System, Inc. 401(k) Employee Stock Ownership Plan Statements of Net Assets Available for Benefits December 31, 2006 and 2005 -------------------------------------------------------------------------------- 2006 2005 ---- ---- Assets Investments, at fair value (Notes B and C): Mutual funds $ 29,648,801 $ 25,795,311 Community Bank System, Inc. common stock 17,216,217 16,199,821 Collective trust fund 14,222,419 12,065,124 Participant loans 1,927,513 1,751,673 Self-directed brokerage 620,068 294,358 Money market fund 360,048 288,273 ------------ ------------ Total investments 63,995,066 56,394,560 Contributions receivable - employer 672,285 761,438 ------------ ------------ Net assets available for benefits at fair value 64,667,351 57,155,998 Adjustment from fair value to contract value for fully benefit-responsive investments 374,339 30,768 ------------ ------------ Net assets available for benefits $ 65,041,690 $ 57,186,766 ============ ============ The accompanying notes are an integral part of the financial statements. 2 Community Bank System, Inc. 401(k) Employee Stock Ownership Plan Statements of Changes in Net Assets Available for Benefits Years Ended December 31, 2006 and 2005 -------------------------------------------------------------------------------- 2006 2005 ---- ---- Additions Employee contributions $ 3,735,218 $ 3,849,739 Employer contributions 1,726,158 1,777,691 Interest income 154,210 87,924 Dividend income 2,718,538 2,060,356 Net appreciation (depreciation) in the fair value of investments 2,298,048 (3,813,500) Transfer from merged plan (Note F) 5,172,272 -- ------------ ------------ Total additions 15,804,444 3,962,210 ------------ ------------ Deductions Benefit payments 7,860,236 5,035,353 Administrative fees 89,284 72,718 ------------ ------------ Total deductions 7,949,520 5,108,071 ------------ ------------ Net increase (decrease) in net assets available for benefits 7,854,924 (1,145,861) Net assets available for benefits Beginning of Year 57,186,766 58,332,627 ------------ ------------ End of Year $ 65,041,690 $ 57,186,766 ============ ============ The accompanying notes are an integral part of the financial statements. 3 Community Bank System, Inc. 401(k) Employee Stock Ownership Plan Notes to Financial Statements December 31, 2006 and 2005 -------------------------------------------------------------------------------- A. Description of the Plan The following description of the Community Bank System, Inc. 401(k) Employee Stock Ownership Plan (the "Plan") provides only general information. Participants should refer to the Plan agreement for a more complete description of the Plan's provisions. General The Plan is a defined contribution plan covering substantially all employees of Community Bank System, Inc. (the "Company") who are age 18 or older. Employees must have one year of service to be eligible for the Company's contribution. The Plan also qualifies as an employee stock ownership plan under the meaning of Section 4975(e)(7) of the Internal Revenue Code. The Plan is subject to the provisions of the Employment Retirement Income Security Act of 1974 (ERISA). Contributions Participants may make voluntary contributions of up to 90% of their total compensation on a pre-tax or after-tax basis up to a maximum contribution of $15,000 for 2006. Voluntary cash contributions of up to 6% of total eligible compensation are matched 50% by the Company and such match was $1,043,113 and $1,016,253 in 2006 and 2005, respectively. The amount of the Company's annual discretionary profit sharing contribution is determined by the Board of Directors, within certain maximum limitations. These discretionary profit sharing contributions to the Plan are allocated to individual participant accounts. Such discretionary profit sharing contributions were $683,045 and $761,438 in 2006 and 2005, respectively. Participant Accounts Each participant's account is credited with the participant's contribution and allocations of the Company's contribution as well as Plan earnings and charged with an allocation of administrative expenses. Allocation of Plan earnings and administrative expenses are based on participant earnings or account balances, as defined. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account. Forfeited accounts are allocated annually to eligible participant accounts based on the ratio of each eligible participant's compensation to total eligible participant compensation. Forfeited accounts allocated to eligible participants amounted to $2,896 and $27,626 for 2006 and 2005, respectively. Vesting Participants are immediately vested in their contributions and the Company's discretionary profit sharing contributions. Vesting in the Company's matching contribution portion plus actual earnings thereon is based on years of continuous service. A participant is 100 percent vested after three years of service. Participant Loans Participants may borrow from the Plan a minimum of $1,000 up to a maximum equal to the lesser of $50,000 or 50 percent of their vested account balance. Loans are collateralized by the balance in the participant's account. 4 Community Bank System, Inc. 401(k) Employee Stock Ownership Plan Notes to Financial Statements December 31, 2006 and 2005 -------------------------------------------------------------------------------- Payment of Benefits Normal retirement date for participants under the Plan is the later of age 65 or the completion of 5 years of service. Upon termination of service due to death, disability or retirement, the participant will receive either a lump sum amount or installment payments equal to the value of the participant's vested interest in his or her account. If some or all of a participant's account balance is allocated to the employee stock option feature of the Plan, that portion of the Plan benefit may be paid in the form of Company stock. Upon termination of employment, if the account balance is less than $5,000, the participant will receive a single lump sum amount equal to the value of his or her account, otherwise, the participant may elect to defer payment up to age 65. Hardship withdrawals of up to 100% of employee contributions are available if Internal Revenue Service guidelines are met. Plan Termination Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue contributions at any time and terminate the Plan subject to the provisions set forth in ERISA. In the event the Plan terminates, the net assets of the Plan are to be set aside for participating employees based upon balances then credited to individual accounts. Participants shall be vested 100% in the assets so allocated to their accounts. B. Significant Accounting Policies Basis of Accounting The accompanying financial statements are prepared on an accrual basis of accounting in accordance with accounting principles generally accepted in the United States of America. Valuation of Investments Investments are stated at aggregate fair value, except for the SEI Stable Asset GIC Fund, which is stated at contract value. Securities that are traded on a national securities exchange are valued at the last reported sales price on the last business day of the Plan year. Shares of mutual funds are valued at the net asset value of shares held by the Plan at year-end. Participant loan receivable balances are reported at cost, which approximates fair value. The Plan presents in the Statement of Changes in Net Assets the net appreciation (depreciation) in the fair value of its investments, which consists of realized gains or losses as well as unrealized appreciation (depreciation) on those investments. Purchases and sales of securities are recorded on the trade date. Gains or losses on sales of securities are based on average cost. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date. The SEI Stable Asset GIC Fund is stated according to the Financial Accounting Standards Board Staff Position, FSP AAG INV-1 and SOP 94-4-1, Reporting of Fully Benefit-Responsive Investment Contracts Held by Certain Investment Companies Subject to the AICPA Investment Company Guide and Defined-Contribution Health and Welfare and Pension Plans ("FSP"), which states that contract value is the relevant measurement attribute for that portion of the net assets available for benefits of a defined-contribution plan attributable to fully benefit-responsive 5 Community Bank System, Inc. 401(k) Employee Stock Ownership Plan Notes to Financial Statements December 31, 2006 and 2005 -------------------------------------------------------------------------------- investment contracts because contract value is the amount participants would receive if they were to initiate permitted transactions under the terms of the plan. As required by the FSP, the accompanying Statements of Net Assets Available for Benefits presents the fair value of the investment contracts as well as the adjustment of the fully benefit-responsive investment contracts from fair value to contract value. The presentation of the 2005 Statement of Net Assets Available for Benefits has been reclassified to comply with the requirements of the FSP. The accompanying Statement of Changes in Net Assets Available for Benefits is prepared on a contract value basis. Contract value represents contributions made under the contract, plus earnings, less participant withdrawals and administrative expenses. Participants may ordinarily direct the withdrawal or transfer of all or a portion of their investments at contract value. There are no reserves against contract value for credit risk of the contract issuer or otherwise. If an event occurs that may impair the ability of the contract issuer to perform in accordance with the contract terms, fair value may be less than contract value. For the year ended December 31, 2006 the average yield utilized was 5.71% and the crediting interest rate to the fund was 4.95%. Payment of Benefits Benefits are recorded when paid. Administrative Expenses Certain administrative expenses are paid by the Company. These amounted to approximately $260,000 and $280,000, including approximately $216,000 and $208,000 paid to Benefit Plans Administrative Services, Inc. ("BPA"), in 2006 and 2005, respectively. (See Note D). Inactive Accounts Account balances of individuals who have withdrawn from participation in the Plan had an accumulated basis of approximately $12,473,617 and $10,553,610 at December 31, 2006 and 2005, respectively. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Risks and Uncertainties The plan provides for various investment options in mutual funds and Company stock. Investment securities are exposed to various risks, such as interest rate, market and credit. Due to the level of risk associated with certain investment securities and the level of uncertainty related to changes in the value of investment securities, it is at least reasonably possible that changes in risk in the near term would materially affect participants' account balances and the amounts reported in the Statements of Net Assets Available for Benefits and the Statements of Changes in Net Assets Available for Benefits. 6 Community Bank System, Inc. 401(k) Employee Stock Ownership Plan Notes to Financial Statements December 31, 2006 and 2005 -------------------------------------------------------------------------------- C.
