REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM ------------------------------------------------------- To the Corning Incorporated Benefits Plan Committee and the Participants of the Corning Incorporated Investment Plan We have audited the accompanying statement of net assets available for benefits of Corning Incorporated Investment Plan (the Plan) as of December 31, 2004, and the related statement of changes in net assets available for benefits for the year 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 audit. We conducted our audit in accordance with the auditing 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. 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 audit provides 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 Corning Incorporated Investment Plan as of December 31, 2004, and the changes in net assets available for benefits for the year then ended, in conformity with U.S. generally accepted accounting principles. Our audit was made for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule of assets (held at end of year) as of December 31, 2004, 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 United States Department of Labor 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.

Corning Incorporated Investment Plan Notes to Financial Statements December 31, 2004 and 2003 -------------------------------------------------------------------------------- (in thousands of dollars) 1. Description of Plan General The following brief description of the Corning Incorporated Investment Plan (the "Plan") is provided for general information purposes only. Participants should refer to the Plan document and summary plan description for a more complete description of the Plan's provisions. The Plan is a defined contribution profit-sharing plan established in January 1967 and is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended ("ERISA"). Effective February 2, 2004, the net assets of the Corning Cable Systems Retirement Plan ("CCSRP") and the Corning Cable Systems Investment Plan ("CCSIP") merged into the Plan. Both CCSRP and CCSIP were sponsored by Corning Incorporated (the "Company"). Administration The Plan is administered by the Corning Incorporated Benefits Committee (the "Committee"), which is appointed by the Board of Directors of the Company. The Committee administers the Plan in accordance with its terms and applicable laws and has all necessary and appropriate powers to carry out the provisions of the Plan. Trustee and Recordkeeper The Plan's assets are held by JPMorgan Chase Bank (the "Trustee"), as trustee. The recordkeeper is Affiliated Computer Services, Inc. (formerly known as Mellon Human Resource and Investor Solutions). Eligibility The Plan covers all employees of the Company and participating subsidiaries who are not members of a union. An employee is eligible for participation in the Plan upon reaching the age of 18 and completing one year of eligible service. Notwithstanding the foregoing, an employee who has attained age 18 and is scheduled on a normal basis to work at least 16 hours a week shall be immediately eligible. Participant Accounts Each participant's account is credited with the participant's contribution and allocations of (a) the Company's contribution and (b) Plan earnings, and charged for administrative expenses. Trustee and investment management fees are deducted from the earnings credited to participant's accounts. A flat monthly fee is charged to each participant's account to subsidize administrative expenses of the Plan and is determined by the plan administrator. Administrative fees, such as investment management fees, are pro-rated among the investment funds as of the last business day of each month. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested balance. Corning Incorporated Investment Plan Notes to Financial Statements December 31, 2004 and 2003 -------------------------------------------------------------------------------- (in thousands of dollars) Vesting Participants are vested immediately in their contributions plus actual earnings thereon. Company contributions to the Plan are fully vested after three years of service. All Company contributions become fully vested upon total and permanent disability, early retirement or normal retirement. Contributions - Employer Depending upon date of hire or employee election, Company matching contributions will be determined under the following provisions: 1) Employees hired on or after July 1, 2000 (and employees hired before July 1, 2000 who so elected) receive matching contributions that equal 100% of the first 2% of eligible pay contributed and 50% of the next 4% of eligible pay contributed, up to 6% of eligible pay. 2) Certain employees hired before July 1, 2000 receive Company matching contributions as a percentage of a participant's first 5% of eligible pay contributed according to years of service as of December 31 of the prior year as follows: Less than 19 years of service 50% 19 but less than 24 years of service 75% 24 or more years of service 100% 3) In 2003, the Company reduced its contributions to the Plan by 2.5% of eligible pay. This applied to all participants except union-free hourly participants. If a participant was entitled to receive both matching and the supplemental contribution, the 2.5% reduction was made proportionally between the two contributions. Effective January 1, 2004, the plan provision adopted in 2003 prescribing a 2.5% of pay reduction in Company contributions was eliminated. With respect to all employees eligible to participate in the Plan and covered by the service-based match described above, beginning in January of the year the participant is expected to reach ten years of vesting service and irrespective of whether such employee has elected to contribute to the Plan, the Company contributes weekly, bi-weekly or monthly (based on the employee's pay frequency) a supplemental contribution to the Corning Common Stock Fund equal to 1.175% of such employee's compensation. Employees hired on or after July 1, 2000 do not receive the supplemental contribution. All Company contributions are invested in the Corning Common Stock Fund. Effective January 1, 2003, participants may transfer Company contributions and associated earnings into any other plan fund. Corning Incorporated Investment Plan Notes to Financial Statements December 31, 2004 and 2003 -------------------------------------------------------------------------------- (in thousands of dollars) Forfeiture credits of $603 were used to reduce employer contributions in 2004. As of December 31, 2004, the amount of forfeitures available to reduce future employer contributions to this plan and the other plan sponsored by the Company with a specific interest in the Corning Incorporated Master Investment Trust is $1,477. Contributions - Participants Generally, participants may contribute up to 75% of their eligible salary on a before-tax basis, after-tax basis or any combination of the two, to the Plan. Prior to October 1, 2003, contributions of highly compensated participants were limited to 1% to 11% of their base salary before tax, and 1% to 4% of their base salary after tax, not to exceed 15% in total. These limits were eliminated July 1, 2004. Effective January 1, 2004, the Plan was amended to limit employees' elections to invest future contributions into the Corning Common Stock Fund. The maximum investment direction election under this new restriction is 20%. The maximum amount a participant can contribute to the Plan on a before-tax basis is $13 per year in 2004 as adjusted by the Internal Revenue Code ("IRC"). The Plan was amended effective July 1, 2004 to permit employees who will have attained age 50 or older during a given year to contribute additional before-tax amounts up to the prescribed IRC limitation for "catch-up contributions." Participants may also elect to have their contributions invested in the Corning Common Stock Fund on a before or after-tax basis. Fund Transfers Participants are allowed to transfer their accumulated contributions between funds. Effective January 1, 2004, the Plan was amended to prohibit the transfer of amounts invested in other Plan investment funds to the Corning Common Stock Fund. Payment of Benefits Benefit payments are made upon retirement (i.e., at least age 55 with five years of service), or in the event of a participant's death, total and permanent disability or other termination of employment. A retired participant can elect to receive distributions in a lump sum, installments, or intermittent withdrawals. The Plan also provides for withdrawals by participants prior to termination. Participant Loans Participants are eligible to obtain loans from the Plan. Loans are limited to one loan per participant with a repayment term not to exceed 4.5 years, except for primary residence loans in which the term may not exceed ten years. The maximum amount of any loan is the lesser of one-half of the vested account balance or $50 (with a $1 minimum). The interest rate on a loan is established by the Committee. Also, participants are charged a loan fee which reduces the loan proceeds.

Summary of Significant Accounting Policies Basis of Presentation The accompanying financial statements are prepared on the accrual basis of accounting. 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 amounts of net assets available for benefits and changes therein. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods could differ from those estimates. Basis of Allocation from the Corning Incorporated Master Investment Trust The Plan has a specific interest in the Corning Incorporated Master Investment Trust (the "Master Trust") in which another plan sponsored by the Company also participates. The Plan's specific interest in the Master Trust is credited or charged for contributions, transfers, and benefit payments relating to its participants. Realized gains and losses and changes in net unrealized appreciation or depreciation on investments, income from investments and expenses are allocated to the Plan based on the Plan's specific interest in the net assets of the Master Trust. At December 31, 2004 and 2003, the Plan's percentage interest in the net assets of the Master Trust was approximately 84% and 81%, respectively. Valuation of Master Trust Investments Master Trust investments in mutual and collective trust funds are recorded at fair value based upon the net asset value announced by the fund on the last business day of the year. Investment contracts are valued at contract value, representing contributions made plus interest at the contract rate, less funds withdrawn and administrative expenses. There are no reserves against contract values for credit risk of the contract issuers or otherwise. Investment contracts are fully benefit-responsive. The Company does not expect any employer initiated events that may cause premature liquidation of a contract at market value. At December 31, 2004 and 2003, investment contracts held by the Master Trust were $407,345 and $421,447, respectively, at contract value. The contract values approximate fair value. The average yield and crediting interest rates were approximately 6% for 2004 and 2003. The crediting interest rates are based on a formula agreed upon with the issuers. Interest is accrued by the Master Trust as earned, and dividends are recorded on the ex-dividend date. Purchases and sales of securities are recorded by the Master Trust on a trade-date basis. Realized gains and losses for security transactions are reported using the average cost method. Unrealized gains and losses represent the difference between the cost and fair value of securities. Valuation of Participant Loans Participant loans are valued at cost plus accrued interest which approximates fair value. Corning Incorporated Investment Plan Notes to Financial Statements December 31, 2004 and 2003 -------------------------------------------------------------------------------- (in thousands of dollars) Payment of Benefits Benefits are recorded when paid. Risks and Uncertainties The Plan's investment securities are exposed to various risks, such as changes in interest rates and market returns. Due to the level of risk associated with certain investments and the level of uncertainty related to changes in the value of these investments, it is at least reasonably possible that changes in valuations in the near term would materially affect participants' account balances and the amounts reported in the Plan's financial statements. 3. Investments The following presents the Master Trust's investments at December 31: 2004 2003 Fixed Income Funds $ 422,902 $ 401,922 Mutual Funds 601,636 410,421 Short-Term Investment Funds 56,120 25,828 Corning Common Stock 497,250 429,456 ------------- ------------- $ 1,577,908 $ 1,267,627 ============= ============= Investments that represent 5% or more of net assets available for benefits as of December 31, 2004 and 2003 were the Plan's interest in the Master Trust. During 2004, the Master Trust's investments (including gains and losses on investments bought and sold, as well as held during the year) appreciated in value by $103,256, as follows: Mutual Funds $ 66,192 Corning Common Stock 37,064 ------------- $ 103,256 ============= During 2004, the Master Trust's investments earned interest and dividends in the amount of $35,135. For 2004, investment expenses totaled $832. Corning Incorporated Investment Plan Notes to Financial Statements December 31, 2004 and 2003 -------------------------------------------------------------------------------- (in thousands of dollars) 4. Plan Termination Although it has not expressed any intent to do so, the Company has the right to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, all amounts credited to participants' accounts will become 100% vested and will be distributed to participants in accordance with Plan provisions. 5. Tax Status The Plan received a favorable determination letter dated November 5, 2003 from the Internal Revenue Service indicating that it meets the requirements of Section 401(a) and 501(a) of the IRC and has qualified status as an employee retirement plan. The Plan has been amended since receiving the determination letter. However, the plan administrator and the Plan's benefits counsel believe that the Plan is designed and is currently being operated in compliance with the applicable provisions of the IRC. 6. Subsequent Events Effective January 1, 2005, participants of the Corning Oak Holding, Inc. Section 401(k) Savings Plan (the Oak Plan) became eligible to participate in the Plan. On February 2, 2005, the assets of the Oak Plan were merged into the Plan. Effective April 1, 2005, the Fidelity Low Priced Stock Fund was eliminated as an investment option for participants. In addition, the Fidelity Mid-cap Stock Fund was replaced with the Vanguard Mid-cap Index Fund. Effective March 28, 2005, the mandatory lump-sum distribution threshold was lowered to $1 to comply with the restrictions set forth under The Economic Growth and Tax Relief Reconciliation Act of 2001 ("EGTRRA").
