TABLE OF CONTENTS

PART I

     (a) General Development of Business

      CLARCOR Inc. (“CLARCOR”) was organized in 1904 as an Illinois corporation and in 1969 was reincorporated in the State of Delaware. As used herein, the “Company” and terms such as “we” or “our” refers to CLARCOR and its subsidiaries unless the context otherwise requires.

      The Company’s fiscal year ends on the Saturday closest to November 30. For fiscal year 2005, the year ended on December 3, 2005 and included 53 weeks. For fiscal year 2004, the year ended November 27, 2004 and included 52 weeks. For fiscal year 2003, the year ended November 29, 2003 and included 52 weeks. In this Form 10-K, all references to fiscal years are shown to begin on December 1 and end on November 30 for clarity of presentation.

     Certain Significant Developments.

      On March 1, 2005, the Company acquired 100% of the shares of Niagara Screen Products Limited (“Niagara”), a Canadian manufacturer of woven wire and metallic screening and filtration products located in St. Catharines, Ontario, Canada, for approximately US $3.4 million in cash. As a result of the acquisition, Niagara is a wholly-owned subsidiary of the Company, reported as part of the Company’s Industrial/ Environmental Filtration segment.

      On November 1, 2005, the Company acquired 100% of the shares of Martin Kurz & Co., Inc. (“MKI”), a privately-owned manufacturer of sintered porous metal laminates used in screening and filtration products for a wide array of industries, including pharmaceutical, petrochemical, aerospace, paper and chemical process industries, for approximately $24.6 million in cash, net of cash received. Based in Mineola, NY, MKI sells products under the Dynapore^® and Foil-Mesh^tm trademarks, among others. As a result of the acquisition, MKI is a wholly-owned subsidiary of the Company, reported as part of the Company’s Industrial/ Environmental Filtration segment.

      During fiscal 2005 these acquired businesses contributed approximately $3.0 million to the Company’s revenues for the year.

      In late November 2005, the Company learned that a major customer of the Company’s Industrial/ Environmental segment intends to begin manufacturing certain products at the customer’s non-U.S. facilities and will cease purchasing these products from the Company at some point in 2006. A fuller discussion of this matter is set forth on page 8 of Exhibit 13(a)(ii) to this Form 10-K — Management’s Discussion and Analysis of Financial Condition and Results of Operation, under the heading “Outlook”.

      (b) Financial Information About Industry Segments

      During 2005, the Company conducted business in three principal industry segments: (1) Engine/ Mobile Filtration, (2) Industrial/ Environmental Filtration and (3) Packaging. These segments are discussed in greater detail below. Financial information for each of the Company’s business segments for the fiscal years 2003 through 2005 is included in Note Q to Notes to Consolidated Financial Statements. See pages F-27 through F-28 in this 2005 Annual Report on Form 10-K (“2005 Form 10-K”).

      (c) Narrative Description of the Business

Engine/Mobile Filtration

      The Company’s Engine/ Mobile segment sells filtration products used on engines and in mobile equipment applications, including trucks, automobiles, buses, locomotives, and marine, construction, industrial, mining and agricultural equipment. The segment’s filters are sold throughout the world, primarily in the replacement market. In addition, some “first-fit” filters are sold to original equipment manufacturers.

      The products in this segment include a full line of oil, air, fuel, coolant, transmission and hydraulic fluid filters which are used in a wide variety of applications and in processes where filter efficiency, reliability and durability are essential. Most of these applications involve a process where impure air or fluid flows through semi-porous paper, corrugated paper, cotton, synthetic, chemical or membrane filter media with varying filtration efficiency characteristics. The impurities contained on the media are disposed of when the filter is changed.

Industrial/Environmental Filtration

      The Company’s Industrial/ Environmental segment centers around the manufacture and marketing of filtration products used in industrial and commercial processes, and in buildings and infrastructures of various types. The segment’s products are sold throughout the world, and include process filtration products and air filtration products and systems used to maintain high interior air quality and to control exterior pollution.

      The segment’s process filtration products include specialty industrial process liquid filters; filters for pharmaceutical processes and beverages; filtration systems for aircraft refueling, anti-pollution, sewage treatment and water recycling; bilge separators; sand control filters for oil and gas drilling; and woven wire and metallic products for filtration of plastics and polymer fibers. These filters use a variety of string wound, meltblown, and porous and sintered and non-sintered metal media, woven wire, and absorbent media.

      The segment’s air filtration products represent a complete line of air filters and cleaners, including antimicrobial treated filters and high efficiency electronic air cleaners. These products are used in commercial buildings, hospitals, factories, residential buildings, paint spray booths, gas turbine systems, medical facilities, motor vehicle cabins, aircraft cabins, clean rooms, compressors and dust collector systems.

Packaging

      The Company’s consumer and industrial packaging products business is conducted by a wholly-owned subsidiary, J. L. Clark, Inc. (“J. L. Clark”).

      J.L. Clark manufactures a wide variety of different types and sizes of containers and packaging specialties. Metal, plastic and combination metal/plastic containers and closures manufactured by the Company are used in packaging a wide variety of dry and paste form products, such as food specialties (e.g., tea, coffee, spices, cookies, candy, mints and other confections); cosmetics and toiletries; playing cards; cosmetics and pharmaceuticals. Other packaging products include shells for dry batteries, film canisters, candles, spools for insulated and fine wire, and custom decorated flat metal sheets.

      Containers and packaging specialties are manufactured only upon orders received from customers, and individualized containers and packaging specialties are designed and manufactured, usually with distinctive decoration, to meet each customer’s marketing and packaging requirements and specifications.

Distribution

      Products in both the Engine/Mobile Filtration and Industrial/ Environmental Filtration segments are sold primarily through a combination of independent distributors, dealers for original equipment manufacturers, retail stores and directly to end-use customers such as truck and equipment fleet users, manufacturing companies and contractors. In addition, both segments distribute products worldwide through their respective foreign subsidiaries and through export sales from the United States to end-use customers.

      During fiscal 2005, the Company continued its development and expansion of its Total Filtration Program, as a distribution channel for all of the Company’s filtration products. Under this Program, the Company offers customers the ability to purchase all of their filters for their respective facilities and manufacturing, transportation and construction equipment — effectively a “one-stop shopping” approach to filtration. Customers that purchase a broad range of filtration products and services from multiple suppliers are able, by taking advantage of the Program, to purchase most of their filter requirements from a single source, and thereby reduce administrative burdens and uncertainty concerning filter pricing, availability, delivery, performance and quality. The Company believes that it can serve its customers’ total filtration requirements

because it believes that it manufactures and supplies the broadest range of filtration products in the industry. The Company expects that the impact of this Program will grow as customers’ facilities are converted to the Program. During fiscal 2005, the Company concentrated on implementing various elements of the Program that are important for the Program’s success over the medium and long-term. These included the further integration of Company branch operations, training sales people to be cross-functional and cross-disciplinary with respect to the Company’s array of filtration products and services, and standardizing back-office IT systems and operational practices across branch offices.

      In the Packaging segment, J.L. Clark uses an internal sales force and sells its products directly to customers for containers and packaging specialties. Each salesperson is trained in all aspects of J.L. Clark’s manufacturing processes with respect to the products sold and is qualified to consult with customers and prospective customers concerning the details of their particular requirements. In addition, salespersons with expertise in specific areas, such as flat-sheet decorating, are focused on specific customers and markets.

Class of Products

      No class of products accounted for 10% or more of the total sales of the Company in any of the Company’s last three fiscal years.

Raw Materials

      Steel, filter media, cartons, aluminum sheet and coil, stainless steel, chrome vanadium, chrome silicon, resins, gaskets, roll paper, corrugated paper, bulk and roll plastic materials and cotton, wood and synthetic fibers and adhesives are the most important raw materials used in the manufacture of the Company’s products. All of these are purchased or are available from a variety of sources. The Company has no long-term purchase commitments. During fiscal 2005 the price of steel and certain hydrocarbon based products (such as resins) purchased by the Company either increased to or remained at high levels. The Company was able to procure adequate supplies of raw materials.

Patents, Trademarks and Tradenames

      Certain features of some of the Company’s products are covered by domestic and, in some cases, foreign patents or patent applications. While these patents are valuable and important for certain products, the Company does not believe that its competitive position is dependent upon patent protection, although as discussed under the heading of “Risk Factors”, the Company believes that patent-related litigation may become more commonplace across all of its business segments, particularly with respect to its engine aftermarket business.

      With respect to trademarks and tradenames, the Company believes that its trademarks used in connection with certain products and certain tradenames (such as “Baldwin”, “Purolator” and “Facet”) are valuable and significant to its business.

Customers

      The largest 10 customers of the Engine/ Mobile Filtration segment accounted for 24% of the $368,183,000 of fiscal year 2005 sales of such segment.

      The largest 10 customers of the Industrial/ Environmental Filtration segment accounted for 24% of the $427,448,000 of fiscal year 2005 sales of such segment.

      The largest 10 customers of the Packaging segment accounted for 63% of the $78,343,000 of fiscal year 2005 sales of such segment.

      No single customer accounted for 10% or more of the Company’s consolidated fiscal year 2005 sales.

Backlog

      At November 30, 2005, the Company had a backlog of firm orders for products amounting to approximately $91,602,000. The backlog figure for November 30, 2004 was approximately $75,900,000. Substantially all of the orders on hand at November 30, 2005 are expected to be filled during fiscal 2006. The Company does not view its backlog as being excessive or problematic, or a significant indication of fiscal 2006 sales levels.

Competition

      The Company encounters strong competition in the sale of all of its products. The Company competes in a number of filtration markets against a variety of competitors. The Company is unable to state its relative competitive position in all of these markets due to a lack of reliable industry-wide data. However, in the replacement market for heavy-duty liquid and air filters used in internal combustion engines, the Company believes that it is among the top five companies worldwide measured by annual sales. In addition, the Company believes that it is a leading manufacturer of liquid and air filters for diesel locomotives. The Company believes that for industrial and environmental filtration products, it is among the top five companies worldwide measured by annual sales.

      In the Packaging segment, its principal competitors include several manufacturers who often compete on a regional basis only and whose specialty packaging segments are smaller than the Company’s. Strong competition is also presented by manufacturers of paper, plastic and glass containers. The Company’s competitors generally manufacture and sell a wide variety of products in addition to packaging products of the type produced by the Company and do not publish separate sales figures relative to these competitive products. Consequently, the Company is unable to state its relative competitive position in those markets.

      The Company believes that it is able to maintain its competitive position because of the quality and breadth of its products and services and the broad geographic scope of its operations.

Product Development

      The Company develops products on its own and in consultation or partnership with its customers. The Company’s Technical Centers and laboratories test product components and completed products to insure high-quality manufacturing results, evaluate competitive products, aid suppliers in the development of product components, and conduct controlled tests of newly designed filters, filtration systems and packaging products for particular uses. Product development departments are concerned with the improvement and creation of new filters and filtration media, filtration systems, containers and packaging products in order to broaden the uses of these items, counteract obsolescence and evaluate other products available in the marketplace.

      In fiscal 2005, the Company employed approximately 100 professional employees on either a full-time or part-time basis on research activities relating to the development of new products or the improvement or redesign of its existing products. During this period the Company spent approximately $9,490,000 on such activities as compared with $7,950,000 for fiscal year 2004 and $7,403,000 for fiscal year 2003.

      During fiscal 2005, the Company spent approximately $3 million in connection with completing approximately 95% of a new aviation fuel test facility in Greensboro, North Carolina. In addition, the Company completed a significant portion of a new media development center in Cincinnati, Ohio. The Company anticipates completing both the Greensboro and Cincinnati centers in the first half of 2006.

Environmental Factors

      The Company is not aware of any facts which would cause it to believe that it is in material violation of existing applicable standards with respect to emissions to the atmosphere, discharges to waters, or treatment, storage and disposal of solid or hazardous wastes.

      The Company is party to various proceedings relating to environmental issues. The U.S. Environmental Protection Agency (EPA) and/or other responsible state agencies have designated the Company as a

potentially responsible party (PRP), along with other companies, in remedial activities for the cleanup of waste sites under the federal Superfund statute.

      Although it is not certain what future environmental claims, if any, may be asserted, the Company currently believes that its potential liability for known environmental matters does not exceed its present accrual of $50,000. However, environmental and related remediation costs are difficult to quantify for a number of reasons, including the number of parties involved, the difficulty in determining the extent of the contamination, the length of time remediation may require, the complexity of environmental regulation and the continuing advancement of remediation technology. Applicable federal law may impose joint and several liability on each PRP for the cleanup of a contaminated site.

      The Company does anticipate, however, that it may be required to install additional pollution control equipment to augment or replace existing equipment in the future in order to meet applicable environmental standards. For example, during fiscal 2003, the Company replaced certain oxidizers used to remove air-borne contaminants at its Rockford, Illinois, packaging manufacturing facility. The cost of this project was about $1.4 million. In 2005 similar equipment was installed at the Company’s packaging manufacturing facility located in Lancaster, Pennsylvania, at approximately the same cost. The Company is presently unable to predict the timing or the cost of any other project of this nature and cannot give any assurance that the cost of such projects may not have an adverse effect on earnings. However, the Company is not aware, at this time, of any other additional significant current or pending requirements to install such equipment at any of its facilities.

Employees

      As of November 30, 2005, the Company had approximately 5,034 employees.

      Our business faces a variety of risks. These risks include those described below and may include additional risks and uncertainties not presently known to us or that we currently deem immaterial. If any of the events or circumstances described in the following risk factors occur, our business, financial condition or results of operations may suffer, and the trading price of our common stock could decline. These risk factors should be read in conjunction with the other information in this 2005 Form 10-K.

      Our financial performance depends, in large part, on varying conditions in the markets that we serve, particularly the general industrial and trucking markets. Demand in these markets fluctuates in response to overall economic conditions and is particularly sensitive to changes in fuel costs, although the replacement nature of our products helps mitigate the effects of these changes. Economic downturns in the markets we serve may result in reductions in sales and pricing of our products, which could reduce future earnings and cash flow.

      We obtain materials and manufactured components from third-party suppliers. Although the majority of these materials and components can be obtained from multiple sources, and while we historically have not suffered any significant limitations on our ability to procure them, any delay in our suppliers’ abilities to provide us with necessary materials and components may affect our capabilities at a number of our manufacturing locations. Delays in obtaining supplies may result from a number of factors affecting our suppliers, including capacity constraints, labor disputes, the impaired financial condition of a particular supplier, suppliers’ allocations to other purchasers, weather emergencies or acts of war or terrorism. Any delay in receiving supplies could impair our ability to deliver products to our customers and, accordingly, could have a material adverse effect on our business, results of operations and financial condition.

      Our operations are subject to U.S. and non-U.S. environmental laws and regulations governing emissions to air; discharges to water; the generation, handling, storage, transportation, treatment and disposal of waste materials; and the cleanup of contaminated properties. Currently, environmental costs with respect to our former or existing operations are not material, but there is no assurance that we will not be adversely impacted by such costs, liabilities or claims in the future, either under present laws and regulations or those that may be adopted or imposed in the future.

      Approximately 22% of our sales result from exports to countries outside of the United States and from sales of our foreign business units. As part of our business strategy, we intend to expand our international operations through internal growth and acquisitions. Sales and operations outside of the United States, particularly in emerging markets, are subject to a variety of risks which are different from or additional to the risks the Company faces within the United States. Among others, these risks include:

      The occurrence of one or more of the foregoing factors could have a material adverse effect on our international operations or upon the financial condition and results of operations.

      The markets in which we operate are highly competitive and highly fragmented. We compete worldwide with a number of other manufacturers and distributors that produce and sell similar products. Our products primarily compete on the basis of price, performance, speed of delivery, quality and customer support. Some of our competitors are companies, or divisions or operating units of companies, that have greater financial and other resources than we do. Any failure by us to compete effectively in the markets we serve could have a material adverse effect on our business, results of operations and financial condition.

      We use a broad range of manufactured components and raw materials in our products, including raw steel, steel-related components, filtration media, resins, plastics, paper and packaging materials. Materials comprise the largest component of our costs, representing over 40% of the costs of our net sales in fiscal 2005. Further increases in the price of these items could further materially increase our operating costs and materially adversely affect our profit margins. Although we try to pass along increased costs in the form of price increases to our customers, we may be unsuccessful in doing so for competitive reasons, and even when successful, the timing of such price increases may lag significantly behind our incurrence of higher costs.

      We have developed and actively pursue developing proprietary technology in the industries in which we operate, and rely on intellectual property laws and a number of patents to protect such technology. In doing so, we incur ongoing costs to enforce and defend our intellectual property. Despite our efforts in this regard, we may face situations where our own intellectual property rights are invalidated or circumvented, to our material detriment. We also face increasing exposure to claims by others for infringement of intellectual property rights, particularly with respect to our aftermarket products. These claims could result in significant costs or losses.

      Our continued success depends on our ability to maintain technological capabilities, machinery and knowledge necessary to adapt to changing market demands as well as to develop and commercialize innovative products, such as innovative filtration media and higher efficiency filtration systems. We may not be able to develop new products as successfully as in the past or be able to keep pace with technological developments by our competitors and the industry generally. In addition, we may develop specific technologies and capabilities in anticipation of customers’ demands for new innovations and technologies. If such demand does not materialize, we may be unable to recover the costs incurred in such programs. If we are unable to recover these costs or if any such programs do not progress as expected, our business, financial condition or results of operations could be materially adversely affected.

      Substantial changes or technological developments in the industries in which our products are used could reduce sales if these changes negatively impact the need for our products. For example, improvements in

engine technology may reduce the need to make periodic filter changes and thus negatively impact our aftermarket filter sales for such engines.

      Our ability to operate our business and implement our strategies depends, in part, on the efforts of our executive officers and other key employees. Our management philosophy of cost-control means that we operate what we consider to be a very lean company with respect to personnel, and our commitment to a less centralized organization (discussed further below) also places greater emphasis on the strength of local management. Our future success will depend on, among other factors, our ability to attract and retain other qualified personnel, particularly management, research and development engineers and technical sales professionals. The loss of the services of any of our key employees or the failure to attract or retain other qualified personnel, domestically or abroad, could have a material adverse effect on our business or business prospects.

      As part of our growth strategy, we plan to pursue the acquisition of other companies, assets and product lines that either complement or expand our existing business. We may be unable to find or consummate future acquisitions at acceptable prices and terms. We continually evaluate potential acquisition opportunities in the ordinary course of business, including those that could be material in size and scope. Acquisitions involve a number of special risks and factors, including:

      Although we conduct what we believe to be a prudent level of investigation regarding the operating and financial condition of the businesses we purchase, an unavoidable level of risk remains regarding the actual operating condition of these businesses. Until we actually assume operating control of these business assets and their operations, we may not be able to ascertain the actual value or understand the potential liabilities of the acquired entities and their operations. This is particularly true with respect to non-U.S. acquisitions.

      We compete for potential acquisitions based on a number of factors, including price, terms and conditions, size and ability to offer cash, stock or other forms of consideration. In pursuing acquisitions, we compete against other strategic and financial buyers, some of which are larger than we are and have greater financial and other resources than we have. Increased competition for acquisition candidates could result in fewer acquisition opportunities for us and higher acquisition prices. In addition, the negotiation of potential acquisitions may require members of management to divert their time and resources away from our operations.

      The Company is relatively decentralized in comparison with its peers. While we believe this practice has catalyzed our growth and enabled us to remain responsive to opportunities and to our customers’ needs, it necessarily places significant control and decision-making powers in the hands of local management. This means that “company-wide” business initiatives, such as our Total Filtration Program and the integration of

disparate information technology systems, are often more challenging and costly to implement, and their risk of failure higher, than they would be in a more centralized environment. Depending on the nature of the initiative in question, such failure could materially adversely affect our business, financial condition or results of operations.

      The Company has no unresolved SEC comments.

      The various properties owned and leased by the Company and its operating units are considered by it to be in good repair and well maintained. Plant asset additions in fiscal 2006 are estimated at $25-$30 million for land, buildings, furniture, production equipment and machinery, and computer and communications equipment.

      The following is a description of the real property owned or leased by the Company or its affiliated entities, broken down by Business Segment. All acreage and square foot measurements are approximate.

ADDITIONAL ITEM: Executive Officers of the Registrant

      The following individuals are the executive officers of the Company as of February 1, 2006:

      Each executive officer of the Company is elected by the Board of Directors for a term of one year which begins at the Board of Directors Meeting at which he or she is elected, held at the time of the Annual Meeting of Shareholders, and ends on the date of the next Annual Meeting of Shareholders or upon the due election and qualification of his or her successor.

PART II

      The Company’s Common Stock is listed on the New York Stock Exchange; it is traded under the symbol CLC.

      On March 21, 2005, the Company’s Board of Directors approved a 100% stock dividend for the purpose of effecting a 2-for-1 stock split of the issued shares of Common Stock of the Company. The record date for the split was April 15, 2005, and the stock dividend was paid on April 29, 2005, doubling the number of shares of Common Stock outstanding at that time to approximately 51,519,588. Unless otherwise indicated, all shares and per share amounts set forth in this report have been adjusted for the 2-for-1 stock split.

      The following table sets forth the high and low market prices as quoted during the relevant periods on the New York Stock Exchange and dividends per share paid for each quarter of the last two fiscal years.

      As set forth above, the quarterly dividend rate was increased in fiscal year 2005, and the Company expects to continue making dividend payments to shareholders.

      The approximate number of holders of record of the Company’s Common Stock at February 1, 2006, 2006 was 1,950. In addition, the Company believes that there are approximately 6,100 beneficial owners whose shares are held in street names.

      On June 17, 2005, the Company’s Board of Directors approved a two-year Stock Repurchase Program, pursuant to which the Company from time to time may purchase up to $150 million worth of shares of the Company’s Common Stock in the open market or through privately negotiated transactions. The Company has no obligation to repurchase shares under the program, and the timing, actual number and value of shares to be purchased depend on market conditions and the Company’s then-current liquidity needs. As of the end of fiscal year 2005, the Company had repurchased approximately 368,200 shares of its Common Stock, at a

median price of $28.41 per share, and an aggregate cost of $10.4 million. The following table sets forth the monthly share purchases by Company in the last fiscal quarter of 2005.

Management’s Report on Internal Control Over Financial Reporting

      The management of CLARCOR is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f), for the Company. Under the supervision and with the participation of management, including the Company’s Chief Executive Officer and Chief Financial Officer, an evaluation of the effectiveness of the Company’s internal control over financial reporting was conducted based on the framework in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”).

      The Company has excluded MKI from its assessment of internal control over financial reporting as of December 3, 2005 because it was acquired by the Company in a purchase business combination during fiscal 2005. MKI is a wholly-owned subsidiary whose total assets and total revenues represent 4% and 0.05%, respectively, of the related consolidated financial statement amounts as of and for the fiscal year ended December 3, 2005.

REPORT OF INDEPENDENT REGISTERED

PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders

CLARCOR Inc.

We have completed integrated audits of CLARCOR Inc.’s 2005 and 2004 consolidated financial statements and of its internal control over financial reporting as of December 3, 2005, and an audit of its 2003 consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Our opinions on CLARCOR’s 2005, 2004 and 2003 consolidated financial statements and on its internal control over financial reporting as of December 3, 2005, based on our audits, are presented below.

Consolidated financial statements and financial statement schedule

In our opinion, the consolidated financial statements listed in the accompanying index present fairly, in all material respects, the financial position of CLARCOR and its subsidiaries at December 3, 2005 and November 27, 2004, and the results of their operations and their cash flows for each of the three years in the period ended December 3, 2005 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedule listed in the index appearing under Item 15(a)(2) presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. These financial statements and financial statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and financial statement schedules based on our audits. We conducted our audits of these statements 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. An audit of financial statements includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

Internal control over financial reporting

Also, in our opinion, management’s assessment, included in Management’s Report on Internal Control Over Financial Reporting appearing under Item 9A, that the Company maintained effective internal control over financial reporting as of December 3, 2005 based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), is fairly stated, in all material respects, based on those criteria. Furthermore, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 3, 2005, based on criteria established in Internal Control — Integrated Framework issued by the COSO. The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express opinions on management’s assessment and on the effectiveness of the Company’s internal control over financial reporting based on our audit. We conducted our audit of internal control over financial reporting 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 effective internal control over financial reporting was maintained in all material respects. An audit of internal control over financial reporting includes obtaining an understanding of internal control over financial reporting, evaluating management’s assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we consider necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial

reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

As described in Management’s Report on Internal Control over Financial Reporting, management has excluded Martin Kurz & Co., Inc. from its assessment of internal control over financial reporting as of December 3, 2005 because it was acquired by the Company in a purchase business combination during 2005. We have also excluded Martin Kurz & Co., Inc. from our audit of internal control over financial reporting. Martin Kurz & Co., Inc. is a wholly-owned subsidiary whose total assets and total revenues represent 4% and 0.05%, respectively, of the related consolidated financial statement amounts as of and for the year ended December 3, 2005.

Principles of Consolidation

      The consolidated financial statements include all domestic and foreign subsidiaries that are more than 50% owned and controlled. CLARCOR Inc. and its subsidiaries are hereinafter collectively referred to as the “Company” or CLARCOR. The Company has three reportable segments: Engine/ Mobile Filtration, Industrial/ Environmental Filtration and Packaging.

Use of Management’s Estimates

      The preparation of the 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 assets and liabilities and disclosure of contingent 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.

Accounting Period

      The Company’s fiscal year ends on the Saturday closest to November 30. The fiscal year ended December 3, 2005 was comprised of fifty-three weeks. The fiscal years ended November 27, 2004 and November 29, 2003 were comprised of fifty-two weeks. In the consolidated financial statements, all fiscal years are shown to begin as of December 1 and end as of November 30 for clarity of presentation.

Reclassifications

      Certain reclassifications have been made to conform prior years’ data to the current presentation. These reclassifications had no effect on reported earnings.

Cash and Cash Equivalents and Short-term Investments

      All highly liquid investments with a maturity of three months or less when purchased or that are readily saleable are considered to be short-term cash equivalents. Management determines the appropriate classification of its investments at the time of acquisition and reevaluates such determination at each balance sheet date. Short-term investments include auction rate securities (ARS) classified as trading securities. Unrealized holding gains and losses, if any, would be included in investment income. There were no unrealized holding gains or losses in any year presented. The carrying amount of cash equivalents and investments approximates fair value. In 2005, the Company began recording its ARS in a separate balance sheet classification.

      The Company reclassified short-term investments on its Consolidated Balance Sheet for 2004 and on its 2004 and 2003 Statements of Cash Flows, which were previously presented as cash and cash equivalents, to present them in accordance with their contractual maturities. The amounts reclassified totaled $5,100 in 2004 and $2,500 in 2003. The purchases and sales related to the investments held in each of the three years ended November 30, 2005 have been presented on the Consolidated Statements of Cash Flows in the operating activities section. This reclassification had no impact on the Consolidated Statements of Earnings or Consolidated Statements of Shareholders’ Equity.

Foreign Currency Translation

      Financial statements of foreign subsidiaries are translated into U.S. dollars at current rates, except that revenues, costs, expenses and cash flows are translated at average rates during each reporting period. Net exchange gains or losses resulting from the translation of foreign financial statements are accumulated with other comprehensive earnings as a separate component of shareholders’ equity and are presented in the Consolidated Statements of Shareholders’ Equity.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Dollars in thousands except per share data) — (Continued)

Derivatives

      During the years presented, the Company did not use any derivatives. However, from time-to-time, the Company may make limited use of derivative financial instruments to manage certain interest rate and foreign currency risks. Interest rate swap agreements could be utilized to convert certain floating rate debt into fixed rate debt. Cash flows related to interest rate swap agreements would be included in interest expense over the terms of the agreements.

      When applicable, the Company documents all relationships between hedging instruments and hedged items, as well as its risk-management objective and strategy for undertaking various hedge transactions. In addition, the Company assesses (both at the hedge’s inception and on an ongoing basis) the effectiveness of the derivatives that are used in hedging transactions. If it is determined that a derivative is not (or has ceased to be) effective as a hedge, the Company would discontinue hedge accounting prospectively. Ineffective portions of changes in the fair value of cash flow hedges would be recognized in earnings.

Comprehensive Earnings

      Foreign currency translation adjustments, unrealized gains and losses on derivative instruments and minimum pension liability adjustments are included in other comprehensive earnings, net of tax.

      The components of the ending balances of accumulated other comprehensive earnings are as follows:

      The minimum pension liability is net of tax of $2,373, $1,089, and $359 for the years ended November 30, 2005, 2004 and 2003, respectively. The translation adjustment is net of tax of $155 for the year ended November 30, 2005. There were no tax effects for prior years’ translation adjustments.

Stock-based Compensation

      In accordance with Statement of Financial Accounting Standards (SFAS) No. 123, “Accounting for Stock-Based Compensation” and SFAS No. 148, “Accounting for Stock-Based Compensation — Transition and Disclosure,” the Company accounts for stock-based compensation using the intrinsic value method as prescribed under Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees,” and related Interpretations and provides the disclosure-only provisions of SFAS No. 123. As discussed under “New Pronouncements”, the Company will adopt SFAS No. 123R, “Share-Based Payment” for its fiscal year 2006.

      If the Company had determined compensation expense for its stock-based compensation plans based on the fair value at the grant dates consistent with the method of SFAS No. 123 and SFAS No. 148, the

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Dollars in thousands except per share data) — (Continued)

Company’s pro forma net earnings and basic and diluted earnings per share (EPS) would have been as follows.

      On November 18, 2005, the Board of Directors approved a grant of 386,375 options that were fully vested on the date of grant. Approximately $3,000 of pretax compensation expense was included in the determination of pro forma earnings during 2005 that otherwise would have been recorded as stock option expense in accordance with SFAS No. 123R, “Share-Based Payment” over future years had the options been granted with a four-year vesting period similar to prior grants.

      On March 22, 2005, the Compensation Committee of the Board of Directors approved accelerating the vesting of nonqualified stock options granted on December 12, 2004 to current employees, including executive officers. All of these options had an exercise price greater than the then-market price per share and provided for vesting at the rate of 25% per year beginning on the first anniversary of the date of grant. Approximately $3,000 of pretax compensation expense was included in the determination of pro forma earnings during 2005 that otherwise would have been recorded as stock option expense in accordance with SFAS No. 123R, “Share-Based Payment” over future years.

Accounts Receivable and Allowance for Losses

      Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for losses is the Company’s best estimate of the amount of probable credit losses in its existing accounts receivable. The Company determines the allowance based on economic conditions in the industries to which the Company sells and on historical experience by evaluating specific customer accounts for risk of loss, fluctuations in amounts owed and current payment trends. The allowances provided are estimates that may be impacted by economic and market conditions which could have an effect on future allowance requirements and results of operations. The Company reviews its allowance for doubtful accounts monthly. Past due balances over 90 days and over a specified amount are reviewed individually for collectibility. Account balances are charged off against the allowance when it is probable the receivable will not be recovered. The Company does not have any off-balance sheet credit exposure related to its customers.

Plant Assets

      Depreciation is determined primarily by the straight-line method for financial statement purposes and by the accelerated method for tax purposes. The provision for depreciation is based on the estimated useful lives of the assets (15 to 40 years for buildings and improvements and 3 to 15 years for machinery and equipment). It is the policy of the Company to capitalize renewals and betterments and to charge to expense the cost of current maintenance and repairs. When property or equipment is retired or otherwise disposed of, the net book value of the asset is removed from the Company’s books and the resulting gain or loss is reflected in earnings.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Dollars in thousands except per share data) — (Continued)

Goodwill and Other Intangible Assets

      The Company recognizes the excess of the cost of an acquired entity over the net amount assigned to assets acquired and liabilities assumed as goodwill. Goodwill is tested for impairment on an annual basis and between annual tests in certain circumstances. Impairment losses would be recognized whenever the implied fair value of goodwill is less than its carrying value.

      The Company recognizes an acquired intangible apart from goodwill whenever the asset arises from contractual or other legal rights, or whenever it is capable of being separated or divided from the acquired entity and sold, transferred, licensed, rented, or exchanged, either individually or in combination with a related contract, asset or liability. An intangible other than goodwill is amortized over its estimated useful life unless that life is determined to be indefinite. The Company’s trade names and trademarks have indefinite useful lives and are subject to impairment testing. All other acquired intangible assets, including patents (average fourteen year life) and other identifiable intangible assets with lives ranging from two to thirty years, are being amortized using the straight-line method over the estimated periods to be benefited. The Company reviews the lives of its definite-lived intangibles annually and if necessary, impairment losses would be recognized if the carrying amount of an intangible subject to amortization is not recoverable from expected future cash flows and its carrying amount exceeds its fair value.

Impairment of Long-Lived Assets

      The Company determines any impairment losses based on underlying cash flows related to specific groups of acquired long-lived assets, including associated identifiable intangibles and goodwill, when events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.

Income Taxes

      The Company provides for income taxes and recognizes deferred tax liabilities and assets for the expected future tax consequences of temporary differences between the financial statement carrying amounts and the tax basis of assets and liabilities.

Revenue Recognition

      Revenue is recognized when product ownership and risk of loss has transferred to the customer or performance of services is complete and the Company has no remaining obligations regarding the transaction. Estimated discounts and rebates are recorded as a reduction of sales in the same period revenue is recognized. Shipping and handling costs are recorded as revenue when billed to customers.

Product Warranties

      The Company provides for estimated warranty costs when the related products are recorded as sales or for specific items at the time their existence is known and the amounts are reasonably determinable.

Research and Development

      The Company charges research and development costs relating to the development of new products or the improvement or redesign of its existing products to expense when incurred. These costs totaled approximately $9,490 in 2005, $7,950 in 2004 and $7,403 in 2003.

Self-Insurance

      The Company self-insures for certain insurable risks, primarily workers’ compensation, general liability, property losses and employee medical coverage. Insurance coverage is generally obtained for catastrophic property and casualty exposures, as well as risks that require insurance by law or contract. Liabilities are

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Dollars in thousands except per share data) — (Continued)

determined using independent actuarial estimates of the aggregate liability for claims incurred and an estimate of incurred but not reported claims, on an undiscounted basis. When applicable, anticipated recoveries are recorded in the same lines in the Consolidated Statements of Earnings in which the losses were recorded, based on management’s best estimate of amounts due from insurance providers.

Guarantees

      The Company has provided letters of credit totaling approximately $25,028 to various government agencies, primarily related to industrial revenue bonds, and to insurance companies and other entities in support of its obligations. The Company believes that no payments will be required resulting from these accommodation obligations.

      In the ordinary course of business, the Company also provides routine indemnifications and other guarantees whose terms range in duration and often are not explicitly defined. The Company does not believe these will have a material impact on the results of operations or financial condition of the Company.

      The Company has a majority ownership interest in a consolidated affiliate in which the Company has agreed, under certain conditions, to buy out the minority owners’ interest for an amount estimated not to exceed $1,400 as of November 30, 2005. In accordance with SFAS No. 150, “Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity”, the Company has recorded this amount at its fair value in other long-term liabilities.

New Pronouncements

      On December 16, 2004, the Financial Accounting Standards Board (FASB) issued SFAS No. 123R, “Share-Based Payment,” which requires companies to expense the value of employee stock options and similar awards. In accordance with a Securities and Exchange Commission rule issued in April 2005, SFAS No. 123R is effective for the Company’s fiscal year beginning December 1, 2005. The Company will also adopt the non-substantive vesting period approach for awards with retirement eligibility options, which requires recognition of compensation expense immediately for grants to retirement eligible employees or over the period from the grant date to the date retirement eligibility is achieved. Adoption of this standard is expected to reduce the Company’s net earnings and earnings per share for interim and annual periods after adoption. Management expects fiscal year 2006 EPS will be reduced by approximately $0.03 under the modified prospective method of reporting based on the unvested options outstanding as of November 30, 2005.

      On December 21, 2004, the FASB issued two FSPs regarding the accounting implications of the American Jobs Creation Act of 2004. FSP No. 109-1, “Application of FASB Statement No. 109 ‘Accounting for Income Taxes’ to the Tax Deduction on Qualified Production Activities Provided by the American Jobs Creation Act of 2004” is not expected to have an effect on the Company’s effective tax rate until fiscal 2006. FSP No. 109-2, “Accounting and Disclosure Guidance for the Foreign Earnings Repatriation Provision within the American Jobs Creation Act of 2004” was effective for fiscal year 2004 and is discussed in Note J.

      On November 1, 2005, the Company acquired Martin Kurz & Co., Inc. (MKI), a privately-owned Mineola, New York manufacturer of sintered porous metal laminates used in screening and filtration products for a wide array of industries, including pharmaceutical, petrochemical, aerospace, paper and chemical process industries, for approximately $24,621 net of cash received, including acquisition expenses. The preliminary purchase price was paid in cash with available funds. MKI’s sales for the most recent twelve months prior to acquisition were approximately $12,000. The acquisition would not have significantly affected net earnings and earnings per share of the Company for prior fiscal years. MKI was acquired to expand the Company’s product line and technical capabilities in filter manufacturing. The Company expects the acquisition to be accretive to

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Dollars in thousands except per share data) — (Continued)

earnings per share in fiscal year 2006. MKI is included in the Industrial/ Environmental segment from the date of acquisition.

      The excess of the initial purchase price over the estimated fair value of the net tangible and identifiable intangible assets acquired was recorded as goodwill. The initial purchase price was based on the net assets of the business acquired as shown on an October 31, 2005, balance sheet which is subject to a final adjustment. The preliminary allocation of the purchase price over the preliminary estimated fair value of the tangible and identifiable intangible assets acquired for MKI resulted in $9,114 recorded as goodwill. In addition based on a preliminary appraisal, the Company recognized $8,600 for customer relationships that will be amortized over twelve years, $267 as indefinite-lived trademarks and $1,700 as other acquired intangibles which will be amortized over five to ten years. The preliminary allocation for MKI will be finalized when the Company completes its estimates of liabilities assumed, completes an appraisal of the assets acquired and finalizes the purchase price with the sellers. The Company expects to do this in fiscal 2006. Following is a preliminary condensed balance sheet based on fair values of the assets acquired and liabilities assumed.

      On March 1, 2005, the Company acquired Niagara Screen Products Limited (Niagara), a manufacturer of woven wire and metallic screening and filtration products, located in St. Catharines, Ontario, Canada for $3,356 in cash. Niagara became a wholly-owned subsidiary of the Company and is included in the Industrial/ Environmental Filtration segment from the date of acquisition. The allocation of the excess of purchase price over the fair value of the tangible and identifiable intangible assets acquired for Niagara resulted in $2,164 recorded as goodwill. In addition, the Company recognized $53 for customer relationships that will be amortized over twenty years. The Company also recorded $382 as exit costs for terminated employees and $78 as plant shutdown costs, both of which were paid during fiscal year 2005. The acquisition would not have significantly affected net earnings and earnings per share of the Company for prior fiscal years.

      On September 15, 2004, the Company acquired certain assets of United EFP, a privately-owned manufacturer of woven wire and metallic screening and filtration products for the plastic and polymer fiber industries, operating through two manufacturing facilities in Houston, Texas and Shelby, North Carolina for $37,188 net of cash received, including acquisition expenses. The purchase price was paid in cash with available funds and proceeds from a revolving credit facility. During 2005, the purchase price was finalized resulting in a $60 payment by the seller to the Company. An increase to goodwill of $282 was recorded primarily as a result of the net settlement payment, entries associated with the valuation of accounts receivable and liabilities assumed and final payment of acquisition expenses. United EFP was renamed Purolator EFP (PEFP) and became a wholly-owned subsidiary reported as part of the Industrial/Environmental Filtration segment. PEFP’s sales in the most recent twelve-month period prior to the acquisition were approximately $25,000. PEFP was acquired in order to expand the Company’s product line and provide strategic growth opportunities, particularly in liquid process filtration applications. The acquisition would not have significantly affected net earnings and earnings per share of the Company for prior fiscal years.

(Dollars in thousands except per share data) — (Continued)

      The excess of the initial purchase price over the estimated fair value of the net tangible and identifiable intangible assets acquired was recorded as goodwill. The purchase price was based on the net assets of the business acquired as shown on a September 14, 2004, balance sheet which was subject to a final adjustment. The allocation of the purchase price over the estimated fair value of the tangible and identifiable intangible assets acquired for PEFP resulted in $16,357 recorded as goodwill in 2004. In addition, the Company recognized $5,204 for customer relationships that is being amortized over twenty years, $18 as indefinite-lived trademarks and $560 as other acquired intangibles which is being amortized over three years.

      Following is a condensed balance sheet based on fair values of the assets acquired and liabilities assumed.

      On March 1, 2004, the Company acquired certain assets of Filtrel Group, a Luton, England manufacturer and distributor of heavy-duty engine air filters for $4,871 in cash. As a result of the acquisition, the assets were combined into existing subsidiaries of the Company in the Engine/ Mobile Filtration segment. An allocation of the purchase price was made to major categories of assets and liabilities. The $3,598 excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired was recorded as goodwill. Other acquired intangibles included a noncompete agreement valued by an independent appraiser at $115, which is being amortized on a straight-line basis over two years. The Company also recorded $50 as exit costs for terminated employees. This amount was paid during the quarter ended May 29, 2004. The acquisition is not material to the results of the Company.

      Inventories are valued at the lower of cost or market determined on the first-in, first-out (FIFO) method of inventory costing which approximates current cost. Inventories are summarized as follows:
