1. CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

Basis of Presentation

CLARCOR Inc. and its subsidiaries (collectively, the “Company” or “CLARCOR”) is a global provider of filtration products, filtration systems and services, and consumer and industrial packaging products. As discussed further in Note 13, the Company has three reportable segments: Engine/Mobile Filtration, Industrial/Environmental Filtration and Packaging. The Consolidated Condensed Financial Statements include all domestic and foreign subsidiaries that were more than 50% owned and controlled as of each respective reporting period presented. All intercompany accounts and transactions have been eliminated.

The Consolidated Condensed Statements of Earnings and the Consolidated Condensed Statements of Cash Flows for the periods ended August 31, 2013 and September 1, 2012 and the Consolidated Condensed Balance Sheet as of August 31, 2013 have been prepared by the Company without audit.  The Consolidated Condensed Financial Statements have been prepared on the same basis as those in the Company’s Annual Report on Form 10-K for the fiscal year ended December 1, 2012 (“2012 Form 10-K”).  The December 1, 2012 Consolidated Condensed Balance Sheet data was derived from the Company’s year-end audited Consolidated Financial Statements as presented in the 2012 Form 10-K but does not include all disclosures required by accounting principles generally accepted in the United States of America ("U.S. GAAP").  In the opinion of management, all adjustments (which include only normal recurring adjustments) necessary to present fairly the financial position, results of operations and cash flows have been made.  The results of operations for the period ended August 31, 2013, are not necessarily indicative of the operating results for the full year.  The information included in this Form 10-Q should be read in conjunction with the audited Consolidated Financial Statements and accompanying notes included in the 2012 Form 10-K.

Cash and Cash Equivalents and Restricted Cash

Highly liquid investments with an original maturity of three months or less when purchased and that are readily saleable are considered to be cash and cash equivalents.  Restricted cash represents funds held in escrow and cash balances held by German banks as collateral for certain guarantees of overseas subsidiaries.  Restricted cash classified as current corresponds to funds held in escrow that will be used within one year or guarantees that expire within one year.  The Company also has $1,883 and $1,839 of noncurrent restricted cash recorded in Other noncurrent assets as of August 31, 2013 and December 1, 2012, respectively, corresponding to guarantees and escrow agreements that expire longer than one year from the dates of the Consolidated Condensed Balance Sheets.

Inventories

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

	August 31, 2013		December 1, 2012
Raw materials	$	79,663	$	75,928
Work in process	36,839		34,996
Finished products	108,111		100,327
Inventories	$	224,613	$	211,251

Property, Plant and Equipment

At December 1, 2012, land of $398 and building and building fixtures of $1,602 related to one Kentucky plant were classified as Assets held for sale. Those assets where sold March 29, 2013 for $2,211 resulting in a gain of $211, which is included in Cost of sales in the accompanying Consolidated Condensed Statements of Earnings for the nine months ended August 31, 2013.

During the third quarter of 2013 the Company made the decision to dispose of certain equipment at our air filtration operations, resulting in a loss of $4,631, which is included in Cost of sales in the accompanying Consolidated Condensed Statements of Earnings for the nine months ended August 31, 2013.

Accumulated Other Comprehensive Loss

The components of the ending balances of Accumulated other comprehensive loss are as follows:

	August 31, 2013			December 1, 2012
Pension liability, net of tax	$	(46,338	)	$	(50,890	)
Translation adjustments, net of tax	(5,367		)	(818		)
Accumulated other comprehensive loss	$	(51,705	)	$	(51,708	)

New Accounting Guidance

In February 2013, the Financial Accounting Standards Board ("FASB") issued guidance to improve the reporting of reclassifications out of accumulated other comprehensive income ("AOCI"). The amendments do not change the current requirement for reporting net income or other comprehensive income in financial statements; however, the amendments require an entity to provide information about the amounts reclassified out of AOCI by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of AOCI by the respective line items of net income, but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail about those amounts. The guidance is effective for annual and interim periods beginning after December 15, 2012, although early adoption is permitted. The Company does not expect the adoption of this guidance on the first day of fiscal year 2014 to have a material impact on the Consolidated Financial Statements.

In July 2012, the FASB issued amendments to its indefinite-lived intangible assets impairment testing guidance to simplify how entities test for indefinite-lived intangible asset impairments. The objective of the amendments is to reduce cost and complexity by providing an entity with the option to make a qualitative assessment about the likelihood that an indefinite-lived intangible asset is impaired to determine whether it should perform a quantitative impairment test. The amendments also enhance the consistency of impairment testing guidance amount long-lived asset categories by permitting an entity to assess qualitative factors to determine whether it is necessary to calculate the asset's fair value when testing an indefinite-lived intangible asset for impairment, which is equivalent to the impairment testing requirements for other long-lived assets. The amendments are effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, although early adoption is permitted. The adoption of this guidance on the first day of fiscal year 2013 did not have a material impact on the Consolidated Financial Statements.

In September 2011, the FASB issued amendments to its goodwill impairment testing guidance to simplify how entities test for goodwill impairments. The amendments are intended to reduce complexity and cost by providing a company the option of making an initial qualitative evaluation about the likelihood of goodwill impairment in determining whether it should calculate the fair value of a reporting unit. The amendments also include examples of events and circumstances that a company should consider in evaluating whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. The amendments are effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011, although early adoption is permitted. The adoption of this guidance on the first day of fiscal year 2013 did not have a material impact on the Consolidated Financial Statements.

In June 2011, the FASB issued amendments to its comprehensive income guidance to (a) improve the comparability, consistency and transparency of financial reporting, (b) increase the prominence of items reported in other comprehensive income and (c) facilitate the convergence of U.S. GAAP with International Financial Reporting Standards ("IFRS"). The amendments require all non-owner changes in shareholders' equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The required amendments, pursuant to the guidance, must be applied retrospectively. In December 2011, the FASB issued amendments to defer certain presentation requirements of the initial guidance. The guidance is effective for fiscal years and interim periods within those years, beginning after December 15, 2011, although early adoption is permitted. The adoption of this guidance on the first day of fiscal year 2013 resulted in the presentation of the Consolidated Condensed Statements of Comprehensive Earnings, but did not have a material effect on the Company’s financial position or results of operations.

2. BUSINESS ACQUISITIONS AND INVESTMENTS

Business Acquisitions

On May 9, 2012, the Company acquired 100% of the shares in Modular Engineering Company Pty Ltd. ("Modular") for $7,875. An initial payment of $5,237 was made at closing. On May 8, 2013, another installment of the purchase price in the amount of $1,530 was paid. The remaining purchase price will be paid on the second anniversary of the closing date. Modular, a manufacturer of pressure vessels, process and storage tanks and other natural gas filtration products and distributor of aftermarket elements is located in Henderson, Western Australia. The acquisition of Modular gave the Company first-fit manufacturing capabilities in Western Australia, as well as a platform for aftermarket growth throughout the region. Modular has been combined into an existing Company subsidiary, which is part of the Company's Industrial/Environmental Filtration segment. An allocation of the purchase price for the acquisition has been made to major categories of assets and liabilities. Acquired finite-lived intangible assets of $2,552 were recorded in connection with the purchase. The $5,339 excess of the initial purchase price over the estimated fair value of the assets acquired and liabilities assumed was recorded as goodwill, which is not deductible for income tax purposes. Net sales and Operating profit (loss) attributable to Modular for the three and nine months endedAugust 31, 2013 and September 1, 2012 were as follows:

	Quarter Ended					Nine Months Ended
	August 31, 2013			September 1, 2012		August 31, 2013			September 1, 2012
Net sales	$	2,012		$	2,941	$	5,639		$	3,513
Operating profit (loss)	(395		)	197		(1,362		)	229

Investments

Effective May 1, 2008, the Company acquired a 30% share in BioProcessH2O LLC (“BPH”), a Rhode Island-based manufacturer of industrial waste water and water reuse filtration systems, for $4,000.  During the three and nine months endedAugust 31, 2013, the Company did not make any additional investments. During the three months ended September 1, 2012, the Company did not make any additional investments. During the nine months endedSeptember 1, 2012, the Company invested an additional $33. The Company also has $21 accrued which has not yet been funded and is included in Accounts payable and accrued liabilities in the accompanying Consolidated Condensed Balance Sheets at both August 31, 2013 and December 1, 2012. Under the terms of the agreement with BPH, the Company has the right, but not the obligation, to acquire additional ownership shares and eventually complete ownership of BPH over several years at a price based on, among other factors, BPH’s operating income.  The investment, with a carrying amount of $3,075 and $3,137, at August 31, 2013 and December 1, 2012, respectively, included in Other noncurrent assets in the Consolidated Condensed Balance Sheets, is being accounted for under the equity method of accounting.  The carrying amount is adjusted each period to recognize the Company’s share of the earnings or losses of BPH, included in Other, net in the Consolidated Condensed Statements of Earnings, based on the percentage of ownership, as well as the receipt of any dividends.  During the three and nine months endedAugust 31, 2013 and September 1, 2012, the Company did not receive any dividends from BPH.  The equity investment is periodically reviewed for indicators of impairment.

The Company also owns a 15.62% share in BioProcess Algae LLC (“Algae”), a Delaware-based company developing technology to grow and harvest algae which can be used to consume carbon dioxide and also be used as a renewable energy source.  During the three and nine months endedAugust 31, 2013, the Company invested an additional $156 and $615, respectively, into Algae, of which $223 had been accrued and included in Accounts payable and accrued liabilities at December 1, 2012 in the accompanying Consolidated Condensed Balance Sheets. During the three and nine months endedSeptember 1, 2012, the Company invested an additional $444 and $768, respectively, into Algae. The investment, with a carrying amount of $2,204 and $1,812 at August 31, 2013 and December 1, 2012, respectively, included in Other noncurrent assets, is being accounted for under the cost method of accounting.  Under the cost method, the Company recognizes dividends as income when received and reviews the cost basis of the investment for impairment if factors indicate that a decrease in value of the investment has occurred.  During the three and nine months endedAugust 31, 2013, the Company did not receive any dividends from Algae. During the three months ended September 1, 2012, the Company did not receive any dividends from Algae. During the nine months endedSeptember 1, 2012, the Company received dividends from Algae of $1,200, which is included in Other, net in the Consolidated Condensed Statements of Earnings.

3. INCENTIVE PLANS AND STOCK-BASED COMPENSATION

On March 23, 2009, the shareholders of CLARCOR approved the 2009 Incentive Plan, which replaced the 2004 Incentive Plan.  The 2009 Incentive Plan allows the Company to grant stock options, restricted stock unit awards, restricted stock, performance awards and other awards to officers, directors and key employees of up to 3,800,000 shares during a ten-year period that ends in December 2019.  Upon share option exercise or restricted stock unit award conversion, the Company issues new shares unless treasury shares are available.  The key provisions of the Company’s stock-based incentive plans are described in Note M of the Company’s Consolidated Financial Statements included in the 2012 Form 10-K.

Stock Options

Nonqualified stock options are granted at exercise prices equal to the market price of CLARCOR common stock at the date of grant, which is the date the Company’s Board of Directors approves the grant and the participants receive it.  The Company’s Board of Directors determines the vesting requirements for stock options at the time of grant and may accelerate vesting.  In general, options granted to key employees vest 25% per year beginning at the end of the first year; therefore, they become fully exercisable at the end of four years.  Vesting may be accelerated in the event of retirement, disability or death of a participant or change in control of the Company.  Options granted to non-employee directors vest immediately.  All options expire ten years from the date of grant unless otherwise terminated.

The following table summarizes information related to stock options and stock option exercises during the three and nine months endedAugust 31, 2013 and September 1, 2012.

The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model with the following weighted average assumptions by grant year.

	Nine Months Ended
	August 31, 2013			September 1, 2012
Weighted average fair value per option at the date of grant for options granted	$	9.98		$	12.49
Risk-free interest rate	1.19		%	1.38		%
Expected dividend yield	1.19		%	0.96		%
Expected volatility factor	25.80		%	26.52		%
Expected option term in years	5.4			6.1

The expected option term in years selected for options granted during each period presented represents the period of time that the options are expected to be outstanding based on historical data of option holder exercise and termination behavior.  Expected volatilities are based upon historical volatility of the Company’s monthly stock closing prices over a period equal to the expected life of each option grant.  The risk-free interest rate is selected based on yields from U.S. Treasury zero-coupon issues with a remaining term approximately equal to the expected term of the options being valued.  Expected dividend yield is based on the estimated dividend yield determined on the date of issuance.

Restricted Stock Unit Awards

The Company’s restricted stock unit awards are considered nonvested share awards.  The restricted stock unit awards require no payment from the employee.  Compensation cost is recorded based on the market price of the stock on the grant date and is recorded equally over the vesting period of four years.  During the vesting period, officers and key employees receive compensation equal to the amount of dividends declared on common shares they would have been entitled to receive had the shares been issued.  Upon vesting, employees may elect to defer receipt of their shares.  There were 14,760 and 131,197 vested and deferred shares at August 31, 2013 and December 1, 2012, respectively.

The following table summarizes information related to restricted stock unit awards during the three and nine months endedAugust 31, 2013 and September 1, 2012.

Directors' Stock Compensation

The incentive plans provide for grants of shares of common stock to all non-employee directors for annual incentive awards, and for grants of shares of common stock to all non-employee directors equal to a one-year annual retainer in lieu of cash at the directors' option. The directors' rights to the shares vest immediately on the date of grant; however, shares issued as annual retainer fees cannot be sold for a six-month period from the date of grant. The following table summarizes information related to directors' stock compensation during the three and nine months endedAugust 31, 2013 and September 1, 2012.

4. NONCONTROLLING INTERESTS

Noncontrolling interests changed as follows during the nine months endedAugust 31, 2013 and September 1, 2012:

	Nine Months Ended
	August 31, 2013					September 1, 2012
	Redeemable		Non-Redeemable			Redeemable			Non-Redeemable

Dividend	—		(206		)	—			—
Noncontrolling interests at end of period	$	1,814	$	948		$	1,707		$	908

Redeemable Noncontrolling Interests

In March 2007, the Company acquired an 80% ownership share in Sinfa SA (“SINFA”), a manufacturer of automotive and heavy-duty engine filters based in Casablanca, Morocco.  As part of the purchase agreement, the Company and the noncontrolling owners each have an option to require the purchase of the remaining 20% ownership shares by the Company after December 31, 2012 which would result in SINFA becoming a wholly owned subsidiary.  As of August 31, 2013, neither the Company nor the noncontrolling owners have exercised the purchase option. The remaining 20% of SINFA owned by the noncontrolling owners has been reported as Redeemable noncontrolling interests and classified as mezzanine equity in the Consolidated Condensed Balance Sheets.  The Redeemable noncontrolling interests is reflected at its carrying value, which is greater than its estimated redemption price. The Redeemable noncontrolling interests will be accreted to the redemption price, through equity, at the point at which the redemption becomes probable.  The Company has not recorded any accretion to date.

5. GOODWILL AND ACQUIRED INTANGIBLE ASSETS

All goodwill is stated on a gross basis, as the Company has not recorded any impairment charges against goodwill. Based on a decline in the net sales of our TransWeb business, in the third quarter of 2013 we performed an impairment review of the related indefinite-lived intangible assets ($900 carrying value) and definite-lived intangible assets ($9,332 carrying value) and determined that the estimated future cash flows of the relevant asset group were sufficient to cover the carrying value and no impairment existed. We also performed an impairment review of goodwill at the related reporting unit, and determined that the estimated fair value of the reporting unit exceeds its book value and no impairment existed. Our analysis includes management judgment and estimates related to future cash flows, which we believe are reasonable. The following table reconciles the activity for goodwill by segment for the nine months endedAugust 31, 2013.  

	Engine/Mobile Filtration			Industrial/ Environmental Filtration			Packaging		Total

6. FAIR VALUE MEASUREMENTS

Fair Value Measurements

The Company measures certain assets and liabilities at fair value as discussed throughout the notes to its quarterly and annual financial statements. Fair value is the exchange price that would be received for an asset or paid to transfer a liability, an exit price, in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants.  Fair value measurements are categorized in a hierarchy based upon the observability of inputs used in valuation techniques.  Observable inputs are the highest level and reflect market data obtained from independent sources, while unobservable inputs are the lowest level and reflect internally developed market assumptions.  The Company classifies fair value measurements by the following hierarchy:

• Level 1 – Quoted active market prices for identical assets

• Level 2 – Significant other observable inputs, such as quoted prices for similar (but not identical) instruments in active markets, quoted prices for identical or similar instruments in markets which are not active and model determined valuations in which all significant inputs or significant value-drivers are observable in active markets

• Level 3 – Significant unobservable inputs, such as model determined valuations in which one or more significant inputs or significant value-drivers are unobservable

Assets or liabilities that have recurring fair value measurements are shown below:

	Fair Value Measurements at Reporting Date
	Total		Level 1		Level 2		Level 3

There were no changes in the fair value determination methods or significant assumptions used in those methods during the nine months endedAugust 31, 2013.  There were no transfers between Level 1 and Level 2 and there were no transfers into or out of Level 3 during the nine months endedAugust 31, 2013. The Company's policy is to recognize transfers on the actual date of transfer. The restricted trust, which is used to fund certain payments for the Company’s U.S. combined nonqualified pension plans, consists of actively traded equity and bond funds. The TransWeb contingent earn-out payment was established in connection with the acquisition of TransWeb on December 29, 2010, and the acquisition-date estimated fair value of the earn-out payment to one of the former owners was $1,018.  The contingent liability for the earn-out payment will continue to be accounted for and measured at fair value until the contingency is settled during fiscal year 2016.  The fair value measurement of the contingent earn-out payment is based primarily on projected 2014 and 2015 TransWeb earnings, which represent significant inputs not observed in the market and thus represents a Level 3 measurement as defined by accounting literature. The contingent consideration payment is revalued to its current fair value at each reporting date.  Any increase or decrease in the fair value, as a result of changes in significant inputs such as the discount rate, the discount period or other factors used in the calculation, is recognized in Selling and administrative expenses in the Consolidated Condensed Statements of Earnings in the period the estimated fair value changes. The fair value of the contingent consideration was estimated using a probability-weighted discounted cash flow model with a discount rate of 13.2%. The fair value of the TransWeb contingent earn-out payment decreased by $1,292, based on changes in the projected earnings of TransWeb, during the nine months endedAugust 31, 2013.

Fair Values of Financial Instruments

The fair values of the Company’s financial instruments, which are cash and cash equivalents, restricted cash, accounts receivable, the restricted trust and accounts payable and accrued liabilities, approximated the carrying values of those financial instruments at both August 31, 2013 and December 1, 2012.  An expected present value technique is used to estimate the fair value of long-term debt.  Long-term debt had a fair value estimate of $16,570 and $16,532 at August 31, 2013 and December 1, 2012, respectively. The Company's fair value estimate of its long-term debt represents a Level 2 measurement as it is based on the current interest rates available to the Company for debt with similar remaining maturities.  The carrying value for the long-term debt at August 31, 2013 and December 1, 2012 is $16,693 and $16,592, respectively.

7. ACCOUNTS PAYABLE, ACCRUED LIABILITIES AND GUARANTEES

Accounts payable and accrued liabilities at August 31, 2013 and December 1, 2012 were as follows:

	August 31, 2013		December 1, 2012
Accounts payable	$	67,965	$	69,206
Accrued salaries, wages and commissions	11,827		16,884
Pension and postretirement healthcare benefits liabilities	240		21,442
Compensated absences	8,804		9,010
Accrued insurance liabilities	7,738		7,733

Other accrued liabilities	26,687		33,780
Accounts payable and accrued liabilities	$	135,558	$	172,262

The Company has letters of credit totaling $28,573 and $23,307 as of August 31, 2013 and December 1, 2012, respectively, issued to various government agencies, primarily related to industrial revenue bonds, and to insurance companies and other commercial entities in support of its obligations. The Company believes that no payments will be required resulting from these obligations.

In the ordinary course of business, the Company also provides routine indemnifications and other guarantees whose terms range in duration and are often 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.

Warranties are recorded as a liability on the balance sheet and as charges to current expense for estimated normal warranty costs and, if applicable, for specific performance issues known to exist on products already sold. The expenses estimated to be incurred are provided at the time of sale and adjusted as needed, based primarily upon experience. Changes in the Company’s warranty accrual, which is included in Other accrued liabilities, are as follows:

	Nine Months Ended
	August 31, 2013			September 1, 2012
Warranty accrual at beginning of period	$	1,533		$	2,580
Warranty accrual added through business acquisitions	—			32

Other adjustments, including currency translation	(2		)	(36		)
Warranty accrual at end of period	$	1,162		$	2,307

8. LONG-TERM DEBT

On April 5, 2012, the Company entered into a five-year multicurrency revolving credit agreement (“Credit Facility”) with a group of financial institutions. Under the Credit Facility, the Company may borrow up to $150,000, which includes a $10,000 swing line sub-facility, as well as an accordion feature that allows the Company to increase the Credit Facility by a total of up to $100,000, subject to securing additional commitments from existing lenders or new lending institutions. At the Company's election, loans made under the Credit Facility bear interest at either (1) a defined base rate, which varies with the highest of the defined prime rate, the federal funds rate, or a specified margin over the one-month London Interbank Offered Rate (“LIBOR”), or (2) LIBOR plus an applicable margin. Swing line loans bear interest at the defined base rate plus an applicable margin. Commitment fees and letter of credit fees are also payable under the Credit Facility. Borrowings under the Credit Facility are unsecured, but are guaranteed by substantially all of the Company's material domestic subsidiaries. The Credit Facility also contains certain covenants customary to such agreements, as well as customary events of default. At August 31, 2013, there were no borrowings outstanding on the Credit Facility. The Credit Facility includes a $50,000 letter of credit sub-facility, against which $16,012 in letters of credit had been issued at both August 31, 2013 and December 1, 2012.

During the three and nine months ended August 31, 2013, the Company recorded a settlement cost of $3,111 related to the scheduled payment of pension benefits payable under our U.S. combined nonqualified pension plan to our former Executive Chairman, who retired from the Company at the end of 2012.

The Company’s policy is to contribute to its qualified U.S. and non-U.S. pension plans at least the minimum amount required by applicable laws and regulations, to contribute to the U.S. combined nonqualified plans when required for benefit payments, and to contribute to the postretirement healthcare benefit plan an amount equal to the benefit payments.  The Company, from time to time, makes voluntary contributions in excess of the minimum amount required as economic conditions warrant. The Company expects to contribute up to the following amounts to its various plans to pay benefits during 2013:

U.S. Qualified Plans	$	2,837
U.S. Combined Nonqualified Plans	21,335
Non-U.S. Plan	340
Postretirement Healthcare Benefit Plan	70
Total expected contributions	$	24,582

During the three and nine months endedAugust 31, 2013, the Company contributed $7,727 and $24,270, respectively, to its various plans. In addition to the plan assets related to its qualified plans, the Company has also funded $1,024 and $1,070 at August 31, 2013 and December 1, 2012, respectively, into a restricted trust for its U.S. combined nonqualified plans (see Note 6).  This trust is included in Other noncurrent assets in the Consolidated Condensed Balance Sheets.

10. INCOME TAXES

The following is a reconciliation of the beginning and ending amount of gross unrecognized tax benefits for uncertain tax positions, including positions which impact only the timing of tax benefits.

	Nine Months Ended
	August 31, 2013			September 1, 2012
Unrecognized tax benefits at beginning of year	$	2,209		$	3,015
Additions for current period tax positions	348			257
Reductions for prior period tax positions	—			(6		)
Reductions for lapse of statue of limitations / settlements	(334		)	(390		)
Changes in interest and penalties	(226		)	38
Unrecognized tax benefits at end of period	$	1,997		$	2,914

At August 31, 2013, the amount of unrecognized tax benefit, that would impact the effective tax rate if recognized, was $1,386.  The Company recognizes interest and penalties related to unrecognized benefits in income tax expense.  At August 31, 2013, the Company had $245 accrued for the payment of interest and penalties.

Due to the various jurisdictions in which the Company files tax returns and the uncertainty regarding the timing of settlements, it is possible that there could be other significant changes in the amount of unrecognized tax benefits in the next twelve months; however, the amount cannot be estimated.

The Company is regularly audited by federal, state and foreign tax authorities.  The Internal Revenue Service has completed its audits of the Company’s U.S. income tax returns through fiscal year 2009.  With few exceptions, the Company is no longer subject to income tax examinations by state or foreign tax jurisdictions for years prior to 2007.

During the nine months endedAugust 31, 2013, the Company recognized a $985 benefit related to the extension of the research and development tax credit in January 2013.

11. CONTINGENCIES

Legal Contingencies

From time to time, the Company is subject to lawsuits, investigations and disputes (some of which involve substantial claimed amounts) arising out of the conduct of its business, including matters relating to commercial transactions, product liability, intellectual property and other matters.  Items included in these other matters are discussed below.  The Company believes recorded reserves in its Consolidated Condensed Financial Statements are adequate in light of the probable and estimable outcomes of the items discussed below and other matters.  Any recorded liabilities were not material to the Company’s financial position, results of operation or liquidity and the Company does not currently believe that any pending claims or litigation, including those identified below, will materially affect its financial position, results of operations or liquidity.

TransWeb/3M

On May 21, 2010, 3M Company and 3M Innovative Properties (“3M”) brought a lawsuit against TransWeb, LLC ("TransWeb") in the United States District Court for the District of Minnesota, alleging that certain TransWeb products infringe multiple claims of certain 3M patents. Shortly after receiving service of process in this litigation, TransWeb filed its own complaint against 3M in the United States District Court for the District of New Jersey, seeking a declaratory judgment that the asserted patents are invalid and that the products in question do not infringe. 3M withdrew its Minnesota action, and the parties are currently litigating the matter in New Jersey.

The litigation in question was filed and underway before the Company acquired TransWeb in December 2010, but the Company assumed the risk of this litigation as a result of the acquisition. On June 3, 2011, TransWeb filed a Second Amended Complaint against 3M, (i) seeking declaratory judgment that the asserted 3M patents are invalid, the TransWeb products in question do not infringe, and the 3M patents are unenforceable due to inequitable conduct by 3M in obtaining the patents, (ii) alleging patent infringement by 3M of a patent held by TransWeb, and (iii) alleging antitrust violations by 3M in connection with certain upstream and downstream markets for fluorinated polymeric filtration media under theories of Walker Process fraud and sham litigation. TransWeb later dropped its patent infringement allegations against 3M, but continued to allege and pursue its inequitable conduct and antitrust claims. Prior to trial, 3M voluntarily dismissed with prejudice the majority of the patent claims 3M had originally brought against TransWeb, but continued to allege infringement by TransWeb of two claims of one of the patents in suit.

A jury trial commenced on November 13, 2012. After 10 days of testimony and deliberation, on November 30, 2012, a six-member jury unanimously found that (i) TransWeb does not infringe the asserted claims of the 3M patent in suit, (ii) the asserted claims of the patent in suit are invalid as being obvious, (iii) 3M violated the antitrust laws in trying to enforce patents obtained through fraud on the United States Patent Office (i.e., Walker Process fraud), (iv) TransWeb is entitled to recoup lost profits of approximately $34 plus its attorneys' fees as damages, and (v) 3M did not engage in "sham" litigation. The jury also rendered a unanimous advisory verdict, which is not binding on the court, that 3M's asserted patents were obtained through inequitable conduct, and thus unenforceable.

The court has not yet decided whether to accept the jury's verdict on inequitable conduct and has not yet issued a final judgment in the case, pending (i) resolution of various post-trial motions made by 3M to set aside the jury verdicts adverse to 3M, and (ii) a separate procedure before a third party Special Master to quantify and qualify TransWeb's attorneys' fees that may be awarded as damages, including those subject to potential trebling under the antitrust laws. Such procedure is anticipated to take until at least September 2013 to resolve.

The Company acquired TransWeb on December 29, 2010.  Of the base purchase price, the Company withheld payment of $17,000 pending resolution of the 3M litigation, which funds could be used by the Company in connection with the same.  Any litigation related amounts incurred in excess of the amount withheld would be expensed and paid by the Company. During the three months ended August 31, 2013, the Company did not apply any legal charges against the withheld payment as the limit had been reached. During the nine months endedAugust 31, 2013, the Company applied legal charges of $531 against the withheld payment.  Since the acquisition, the Company has incurred legal charges of $18,258 related to the 3M litigation, of which $17,000 has been applied against the withheld portion of the TransWeb purchase price as noted above. During the three and nine months endedAugust 31, 2013, the Company expensed $384 and $1,258, respectively, related to the 3M litigation, which is included in Selling and administrative expenses in the Consolidated Condensed Statements of Earnings.

Other

Additionally, the Company is party to various proceedings relating to environmental issues.  The U.S. Environmental Protection Agency and/or other responsible state agencies have designated the Company as a potentially responsible party, along with other companies, in remedial activities for the cleanup of waste sites under the Comprehensive Environmental Response, Compensation, and Liability Act (“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 is not material.  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 nature and extent of the contamination at issue, the length of time remediation may require, the complexity of the environmental regulation and the continuing advancement of remediation technology.  Applicable federal law may impose joint and several liability on each potentially responsible party for the cleanup.

In addition to the matters cited above, the Company is involved in legal actions arising in the normal course of business.  The Company records provisions with respect to identified claims or lawsuits when it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Claims and lawsuits are reviewed quarterly and provisions are taken or adjusted to reflect the status of a particular matter.

Other Contingencies

In the event of a change in control of the Company, termination benefits are likely to be required for certain executive officers and other employees.

12. EARNINGS PER SHARE AND STOCK REPURCHASE ACTIVITY

The Company calculates basic earnings per share by dividing net earnings by the weighted average number of shares outstanding.  Diluted earnings per share reflects the impact of outstanding stock options, restricted stock and other stock-based arrangements.  The FASB has issued guidance requiring unvested share-based payment awards containing nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) be considered participating securities and included in the computation of earnings per share pursuant to the two-class method.  The Company’s unvested restricted stock unit awards discussed in Note 3 qualify as participating securities under this guidance.  However, the unvested restricted stock unit awards do not materially impact the calculation of basic or diluted earnings per share; therefore, the Company does not present the two-class method computation.  The following table provides a reconciliation of the numerators and denominators utilized in the calculation of basic and diluted earnings per share.

Third Quarter

Net Sales

Net sales increased $2.4 million, or 1%, in the third quarter of 2013 from the third quarter of 2012. Estimated components of this 1% increase in net sales are as follows:

Volume	1	%
Pricing	—	%
Modular acquisition	—	%
Foreign exchange	—	%
	1	%

Our $2.4 million, or 1%, increase in net sales in the third quarter of 2013 from the third quarter of 2012 was driven by a $2.3 million, or 2%, increase in net sales at our Engine/Mobile Filtration segment and a $1.1 million, or 1%, increase in net sales at our Industrial/Environmental Filtration segment, partially offset by a $1.0 million, or 5%, decrease in net sales at our Packaging segment.

• The $2.3 million, or 2%, increase in net sales at our Engine/Mobile Filtration segment primarily resulted from $3.9 million, or 5%, higher sales within the U.S., partly offset by a $1.3 million, or 3%, decrease in foreign sales and by a $0.3 million decrease due to changes in foreign currency exchange rates. The 5% increase in U.S. sales in this segment was driven by a 6% increase in sales of heavy-duty engine filters to the U.S. aftermarket. The decrease in foreign sales was driven by a 10% decline in sales of heavy-duty engine filters in Europe, partially offset by a 5% increase in export sales of heavy-duty engine filters to Canada, Southeast Asia and South America.

• The $1.1 million, or 1%, increase in net sales at our Industrial/Environmental Filtration segment was caused by a $2.5 million, or 7%, increase in foreign net sales, partly offset by a $1.4 million, or 1%, decrease in sales within the U.S. The 7% increase in foreign net sales primarily resulted from increased sales of natural gas vessels and aftermarket filters in Latin America and increased sales of refinery and petrochemical vessels and aftermarket filters in Europe. These effects were partly offset by lower foreign net sales of military aviation and marine filters and dust collector systems in Europe, lower sales from our Modular Engineering business in Australia, and lower sales of aerospace, oil drilling and other industrial filters. The 1% decrease in sales within the U.S. was driven by declines in sales of air filtration products, dust collector systems and filtration media. These lower sales were partly offset by increased sales within the U.S. of aviation and natural gas vessels and aftermarket filters, and increased aerospace filter sales.

• The $1.0 million, or 5%, decrease in net sales at our Packaging segment was driven primarily by lower sales of decorated flat sheet metal products, film packaging products and confection packaging products, partially offset by higher sales of spice containers.

Cost of Sales

Cost of sales increased $5.4 million, or 3%, in the third quarter of 2013 from the third quarter of 2012. As a result, our gross margin decreased to 31.8% in the third quarter of 2013 from 33.1% in the third quarter of 2012. This decrease was primarily caused by a $4.6 million loss on disposal of equipment at our air filtration operations in the third quarter of 2013, reflecting our strategic focus within our air filtration operations on higher-end air filtration products that are not manufactured with this equipment. Gross margin was positively impacted by a less than one percent increase in selling prices of our products and a decrease in our material purchase costs of approximately 1% from the third quarter of 2012, reflecting our continued focus on cost reduction initiatives.

Selling and Administrative Expenses

Selling and administrative expenses increased $1.2 million, or 2%, in the third quarter of 2013 from the third quarter of 2012. This increase was primarily the result of a $3.1 million settlement charge in the third quarter of 2013 related to the scheduled payment of pension benefits under our U.S. combined nonqualified pension plan to our former Executive Chairman, who retired from the Company at the end of 2012. This was partially offset by lower expense of $1.4 million in the third quarter of 2013 from the third quarter of 2012 related to a change in the estimated contingent liability for a potential earn-out

Page 24

payment to one of the former owners of our TransWeb subsidiary. Since selling and administrative expenses increased 2% while sales increased 1%, our selling and administrative expenses as a percentage of net sales increased to 17.3% in the third quarter of 2013 from 17.0% in last year's third quarter.

First Nine Months

Net Sales

Net sales increased $4.1 million, or 1%, in the first nine months of 2013 from the first nine months of 2012. We estimate that volume and changes in foreign exchange rates each resulted in a less than one percent decrease in net sales in the first nine months of 2013 from the first nine months of 2012, while pricing and acquisitions each resulted in a less than one percent increase in net sales in the first nine months of 2013 from the first nine months of 2012.

Our $4.1 million, or 1%, increase in net sales in the first nine months of 2013 from the first nine months of 2012 reflects a $4.7 million, or 1%, increase in net sales at our Industrial/Environmental Filtration segment and a $1.3 million, or less than one percent, increase in net sales at our Engine/Mobile Filtration segment, partially offset by a $1.9 million, or 3%, decrease in net sales at our Packaging segment.

• The $4.7 million, or 1%, increase in net sales at our Industrial/Environmental Filtration segment was driven by $2.1 million in higher sales arising from our acquisition of Modular Engineering Pty Ltd in Australia in the second quarter of 2012. Excluding the impact of the Modular acquisition, net sales at our Industrial/Environmental Filtration segment increased $2.6 million, or 1%, as growth in natural gas vessels and aftermarket filter sales in the U.S. and Latin America, as well as growth in refinery, petrochemical and aviation filter sales and growth in filter sales through our Total Filtration Services ("TFS") distribution business were partially offset by lower sales of military aviation and marine filters and dust collection systems in Europe, lower sales of commercial and industrial air filters in the U.S. and lower filtration media sales at TransWeb.

• The $1.3 million, or less than one percent, increase in net sales at our Engine/Mobile Filtration segment was driven by a 2% increase in U.S. sales in this segment, which was primarily due to a 2% increase in sales of heavy-duty engine filters to the U.S. aftermarket. This was partially offset by a 1% decrease in foreign sales, which was due primarily to a 9% decline in heavy-duty engine filter sales in Europe, partially offset by increased export sales of heavy-duty engine filters in Canada, Southeast Asia and South America.

• The $1.9 million, or 3%, decrease in net sales at our Packaging segment reflects lower sales of film packaging products, confection packaging products and decorated flat sheet metal products, partly offset by growth in spice containers and packaging sales to the battery and smokeless tobacco markets.

Cost of Sales

Cost of sales increased $11.8 million, or 2%, in the first nine months of 2013 from the first nine months of 2012. This increase was greater than the 1% increase in net sales. As a result, our gross margin decreased to 32.6% in the first nine months of 2013 from 33.7% in the first nine months of 2012. This decrease was driven by a $4.6 million loss on disposal of equipment at our air filtration operations in the third quarter of 2013. Our material purchase costs decreased approximately 1% from the first nine months of 2012. However, we experienced lower fixed cost absorption due to lower sales at our air filtration, filtration media and packaging businesses as well as due to costs related to increased capacity and infrastructure to support expected future growth, including the expansion of our manufacturing facility in Yankton, South Dakota.

Selling and Administrative Expenses

Selling and administrative expenses declined $3.3 million, or 2%, in the first nine months of 2013 from the first nine months of 2012. This reduction was primarily the result of $4.0 million lower pension and postretirement benefits plan expense, $1.9 million lower expense related to stock-based compensation, $1.4 million lower expense related to a change in the estimated contingent liability for a potential earn-out payment to one of the former owners of our TransWeb subsidiary and $0.9 million lower compensation expense related to our company-wide profit sharing program. This reduction was partially offset by a $3.1 million settlement charge in the third quarter of 2013 related to the scheduled payment of pension benefits under our U.S. combined nonqualified pension plan to our former Executive Chairman, who retired from the Company at the end of 2012, and by a $1.3 million increase in expenses related to the TransWeb/3M litigation. The increase in expenses related to the TransWeb/3M litigation reflects amounts incurred in excess of the $17.0 million withheld from the base purchase price when we acquired TransWeb. Since

Page 25

selling and administrative expenses decreased 2% while sales increased 1%, our selling and administrative expenses as a percentage of net sales decreased to 17.6% in the first nine months of 2013 from 18.1% in last year's first nine months.

Other Items

Other significant items impacting the comparison between the periods presented are as follows:

• Acquisitions

The acquisition of Modular Engineering Company Pty Ltd. ("Modular") in the second quarter of 2012 impacted our net sales and operating profit (loss) in the third quarter and first nine months of 2013 compared to the third quarter and first nine months of 2012 as follows:

(Dollars in thousands)	Third Quarter			First Nine Months
Net sales	$	(929	)	$	2,126
Operating loss	(592		)	(1,591		)

The decline in sales at Modular in the third quarter of 2013 compared to the third quarter of 2012 was driven by the timing of several large projects in the third quarter of 2012 that did not repeat this year. The operating results at this acquired company in the third quarter and first nine months of 2013 reflect planned investments during these periods in product development and engineering capabilities, the addition of selling and administrative resources to support our long-term growth initiatives, as well as the impact of $0.2 million of bad debt expense relating to a customer bankruptcy during the first quarter of 2013.

• Foreign Exchange

The average exchange rates for foreign currencies versus the U.S. dollar unfavorably impacted our 2013 translated U.S. dollar value of net sales and operating profit compared to the same periods in 2012 as follows:

(Dollars in thousands)	Third Quarter			First Nine Months
Net sales	$	(265	)	$	(659	)
Operating loss	(214		)	(401		)

• Other income (expense)

Interest income (expense)

Net interest income (expense) in the third quarter and first nine months of each of 2013 and 2012 was not significant.

Foreign currency gains and (losses)

We recognized foreign currency gains (losses) in other income (expense) primarily from the translation of cash accounts at certain foreign subsidiaries denominated in currencies other than their functional currencies as follows:

(Dollars in thousands)	Third Quarter			First Nine Months
2013	$	95		$	(137	)
2012	(184		)	(701		)

Other income (expense)

There was no significant other income (expense) in the third quarter of 2013 or in the third quarter of 2012. There was no significant other income (expense) in the first nine months of 2013. Other income (expense) in the first nine months of 2012 included the receipt of a $1.2 million dividend pursuant to our investment in BioProcess Algae LLC.

Page 26

• Provisions for income taxes

Our effective tax rate decreased 2.1 percentage points to 31.8% in the third quarter of 2013 from 33.9% in the third quarter of 2012 primarily due to the extension of the research and development tax credit in December 2012 and various tax planning activities. Our effective tax rate decreased 1.3 percentage points in the first nine months of 2013 from the first nine months of 2012 primarily from a $1.0 million benefit in the first nine months of 2013 related to the extension of the research and development tax credit in December 2012 and from various tax planning activities.

• Shares outstanding

Average diluted shares outstanding decreased by 0.3 million shares in the third quarter of 2013 and by 0.5 million in the first nine months of 2013 from the comparable prior year periods of 2012 as our repurchases of common stock were only partially offset by incremental dilutive shares related to stock option exercises and the issuance of stock options and restricted shares.

The net changes in U.S. net sales for our Engine/Mobile Filtration segment in the third quarter and first nine months of 2013 from the comparable periods in 2012 are detailed as follows:

(Dollars in thousands)	Third Quarter		First Nine Months
Heavy-duty engine filters	$	3,275	$	2,751
Locomotive filters	299		635
Other	349		675
Increase in U.S. net sales	$	3,923	$	4,061

Our U.S. net sales increased 5% in the third quarter of 2013 compared with the same period in 2012, primarily reflecting a 6% increase in heavy-duty engine filter aftermarket sales, which was driven by improved year-over-year demand from our U.S. independent distributors--our primary distribution channel. This growth exceeded the 5% year-over-year increase in heavy-duty truck tonnage for the preceding three months as measured by the American Trucking Associations, which we believe is a leading indicator of heavy-duty engine filter aftermarket demand in the U.S. We also experienced growth of approximately 7% in locomotive filter sales in the third quarter of 2013 compared with the same period in 2012, as well as growth in dust collection cartridge filter sales. Our U.S. net sales increased 2% in the first nine months of 2013 compared with the same period in 2012, primarily driven by a 2% increase in heavy-duty engine filter aftermarket sales.

The net changes in foreign net sales (adjusted for changes in foreign currencies) for our Engine/Mobile Filtration segment in the third quarter and first nine months of 2013 from the comparable periods in 2012 are detailed as follows:

(Dollars in thousands)	Third Quarter			First Nine Months
Export sales primarily to Southeast Asia, South America and the Middle East	970			1,367
Heavy-duty engine filter sales in Australia	(356		)	(388		)
Heavy-duty engine filter sales in Europe	(1,062		)	(3,152		)
Other	(888		)	105
Decrease in foreign net sales	$	(1,336	)	$	(2,068	)

Our foreign net sales decreased 3% in the third quarter of 2013 compared with the same period in 2012 and decreased 1% in the first nine months of 2013 compared with the same period in 2012. These declines in net sales were primarily the result of decreased sales in Europe, where our sales of heavy-duty engine filters declined 10% in the third quarter of 2013 and 9% in the first nine months of 2013 compared with the same periods in 2012, which we believe was primarily driven by lingering macroeconomic conditions in Europe. Sales of heavy-duty engine filters in Australia declined 10% in the third quarter of 2013 and 4% in the first nine months of 2013 compared with the same periods in 2012. These lower sales in Europe and Australia were partially offset by increased export sales of heavy-duty engine filters to Southeast Asia, South America and the Middle East during these periods.

Cost of Sales

Cost of sales increased $1.5 million, or 2%, in the third quarter of 2013 from the third quarter of 2012. This increase was consistent with the 2% increase in net sales. As a result, our gross margin stayed flat at 36.1% in the third quarter of 2013 from 36.1% in the third quarter of 2012. Our material costs and our pricing improved compared with the third quarter of 2012, as we experienced material cost decreases related to changes in product mix and were able to generate cost savings from our continuous cost reduction activities. This was offset by increased manufacturing overhead, primarily due to the impact of additional capacity brought into service to support expected future growth.

Cost of sales increased $4.0 million, or 2%, in the first nine months of 2013 from the first nine months of 2012. This increase was greater than the less than one percent increase in net sales. As a result, our gross margin decreased to 35.6% in the first nine months of 2013 from 36.4% in the first nine months of 2012. Our material costs and our pricing improved compared with the first nine months of 2012, as we experienced material cost decreases related to changes in product mix and we were able to generate cost savings from our continuous cost reduction activities. This was offset by increased manufacturing overhead, primarily

Page 30

reflecting lower absorption of fixed manufacturing costs due to the impact of additional capacity brought into service to support expected future growth.

Selling and Administrative Expenses

Selling and administrative expenses increased $0.6 million, or 3%, in the third quarter of 2013 from the third quarter of 2012. This increase was primarily the result of $0.4 million higher legal and other professional services expenses and $0.4 million higher bad debt expenses. With selling and administrative expenses in this segment increasing 3% while segment net sales increased 2%, our selling and administrative expenses as a percentage of net sales increased to 13.9% in the third quarter of 2013 from 13.7% in the third quarter of 2012.

Selling and administrative expenses decreased $2.4 million, or 4%, in the first nine months of 2013 from the first nine months of 2012. This reduction was primarily the result of $1.2 million lower employee costs related to stock-based compensation and pension and postretirement benefits and $1.2 million lower legal and other professional services expenses. With selling and administrative expenses in this segment declining 4% while our net sales increased less than one percent, our selling and administrative expenses as a percentage of net sales declined to 14.2% in the first nine months of 2013 from 14.9% in the first nine months of 2012.

• Higher sales in the natural gas market in the third quarter and first nine months of 2013 from the comparable periods of 2012 were driven by an increase in natural gas vessel and replacement element sales arising from increased natural gas extraction and transportation activity throughout the U.S., including at various shale gas basins.

• Higher sales in the aviation market in the third quarter and first nine months of 2013 from the comparable periods of 2012 were driven by increased sales of commercial and military aviation filtration products, including filter separators, coalescers, and replacement cartridges used at various filtration points related to the storage, transportation and dispensing of aviation fuel.

• Higher sales through our TFS distribution subsidiary in the the third quarter and first nine months of 2013 from the comparable periods of 2012 were primarily the result of higher liquid and air filter sales to a variety of customers, including those in the automotive, food and beverage and heavy equipment markets.

• Lower dust collection system sales in the third quarter and first nine months of 2013 from the comparable period in 2012 were primarily the result of lower sales of Dust Hog^® weld fume collection systems and Smog Hog^® industrial mist collection systems by our United Air Specialists subsidiary.

• Lower sales of filtration media at TransWeb in the third quarter and first nine months of 2013 from the comparable periods of 2012 were primarily the result of lower order volume from a significant customer.

• Lower sales of air filtration products in the third quarter and first nine months of 2013 from the comparable periods of 2012 were driven by lower sales of heating, ventilation and air conditioning filters to various commercial and industrial customers and lower swine filtration sales due to continuing negative impact of drought conditions in much of the U.S. and the resultant impact on capital spending decisions by agricultural customers.

The net changes in foreign net sales (including export sales and excluding the impact of changes in foreign currency exchange rates) for the Industrial/Environmental Filtration segment in the third quarter and first nine months of 2013 from the comparable periods of 2012 are detailed as follows:

(Dollars in thousands)	Third Quarter			First Nine Months
Natural gas vessels and aftermarket filters (Middle East, Asia, South America, Canada)	$	3,625		$	6,414

Increase in foreign net sales	$	2,476		$	4,314

• Higher sales of natural gas vessels and aftermarket filters in the third quarter and first nine months of 2013 from the comparable prior year periods were driven by increased natural gas extraction, processing and transportation activity in Latin America, where we continue to develop key customer relationships. These increased sales were partially offset by lower sales in Canada and Southeast Asia. Lower sales in Canada reflect lower export demand from the U.S., as increased U.S. natural gas production, including at various shale gas basins, has lowered demand for natural gas exports from Canada.

• Higher sales of refinery and petrochemical vessels and aftermarket filters in the third quarter and first nine months of 2013 compared to the same periods last year were driven by the timing of several large petrochemical system orders in Europe in 2013.

• Sales of dust collector systems increased in the third quarter of 2013 from the comparable prior year period, driven by increased sales in China, partially offset by lower demand for industrial dust, fume and oil mist collectors in Europe, which we believe was primarily due to weak macroeconomic conditions in Europe. These lower sales in Europe have driven lower overall sales of dust collector systems in the first nine months of 2013 from the comparable prior year period.

• Lower export sales of aerospace, off-shore oil drilling and other industrial filters in the third quarter and first nine months of 2013 from the comparable prior year periods were driven by lower sales of sand control screen filters to the oil and gas drilling industry, due primarily to timing issues with a major customer. These lower sales were partially offset by higher sales of cabin air, hydraulic and waste tank filters to the aerospace industry.

• Lower sales of military aviation and marine filtration products in the third quarter and first nine months of 2013 compared to the same periods last year were driven by lower government military spending in Europe, which we believe was primarily driven by lingering adverse macroeconomic conditions in Europe.

Cost of Sales

Cost of sales increased $4.9 million, or 5%, in the third quarter of 2013 from the third quarter of 2012. This increase was greater than the 1% increase in net sales. As a result, our gross margin decreased to 29.5% in the third quarter of 2013 from 32.5% in the third quarter of 2012. This decrease was driven by a $4.6 million loss on disposal of equipment at our air filtration operations in the third quarter of 2013. Our gross margin was positively impacted by a reduction in material purchase costs of approximately 1% in the third quarter of 2013 from the third quarter of 2012, partially offset by lower fixed cost absorption due to lower sales at our air filtration and filtration media businesses.

Cost of sales increased $9.7 million, or 4%, in the first nine months of 2013 from the comparable period of 2012, while net sales increased 1%. As a result, our gross margin decreased to 31.6% in the first nine months of 2013 from 33.3% in the first nine months of 2012. This decrease was driven by a $4.6 million loss on disposal of equipment at our air filtration operations in the third quarter of 2013. Although we realized some reductions in direct material and labor costs through our continuous improvement initiatives in the first nine months of 2013, our material and overhead costs as a percentage of net sales increased approximately 3% in the first nine months of 2013 from the comparable prior year period. This increase was due primarily to an increased sales

Page 33

mix of natural gas vessels, which carry higher material content in comparison to filter elements and other replacement filters, and lower absorption of fixed manufacturing overhead due to lower sales of air filtration products and lower sales of filtration media.

Selling and Administrative Expenses

Selling and administrative expenses increased $0.6 million, or 2%, in the third quarter of 2013 from the third quarter of 2012. This increase was primarily the result of $0.4 million higher legal and other professional services expenses and $0.3 million higher bad debt expense. With selling and administrative expenses increasing 2% while our net sales increased 1%, our selling and administrative expenses as a percentage of net sales increased to 21.4% in the third quarter of 2013 from 21.1% in last year's third quarter.

Selling and administrative expenses decreased $0.2 million, or less than one percent, in the first nine months of 2013 from the comparable period of 2012. This decrease was primarily the result of lower employee costs related to stock-based compensation and pension and postretirement benefits, and lower compensation expense related to our profit sharing program, partially offset by higher legal and other professional services expenses and higher bad debt expenses. With selling and administrative expenses decreasing less than one percent while our net sales increased 1%, we reduced our selling and administrative expenses as a percentage of net sales to 21.7% in the first nine months of 2013 from 22.1% in the comparable period of 2012.

Decrease in U.S. net sales	$	(979	)	$	(1,874	)

Lower sales of film packaging in the third quarter and first nine months of 2013 from the comparable periods of 2012 were driven by lower sales of metal lithography film cannisters due to a continued migration within the film industry from analog to

Page 34

digital technologies. Lower sales of confection packaging during these periods were primarily due to the loss of a significant customer in 2012. The increase in spice packaging sales in the third quarter and first nine months of 2013 compared to the prior year was due to increased order volume from both branded and private label customers.

Cost of Sales

Cost of sales decreased $1.0 million, or 6%, in the third quarter of 2013 from the third quarter of 2012. This decrease was primarily driven by the 5% decrease in net sales. Gross margin increased to 20.6% in the third quarter of 2013 from 19.2% in the third quarter of 2012. This increase was primarily related to lower depreciation costs as certain assets reached the end of their depreciable lives.

Cost of sales decreased $1.9 million, or 4%, in the first nine months of 2013 from the first nine months of 2012. This decrease was primarily driven by the 3% decrease in net sales. Gross margin increased to 19.3% in the first nine months of 2013 from 18.7% in the first nine months of 2012. This increase was primarily related to improved absorption of fixed manufacturing costs as production volumes increased to provide inventory in support of targeted customer service levels.

Selling and Administrative Expenses

Selling and administrative expenses were $2.1 million in the third quarter of 2013 and in the third quarter of 2012. With selling and administrative expenses staying flat while our net sales decreased 5%, our selling and administrative expenses as a percentage of net sales increased to 10.5% in the third quarter of 2013 from 10.0% in last year's third quarter.

Selling and administrative expenses declined $0.6 million, or 10%, in the first nine months of 2013 from the first nine months of 2012. This decrease was driven by $0.2 million of bad debt expense recognized in the first nine months of 2012 pursuant to the Kodak bankruptcy, as well as lower employee costs related to stock-based compensation and pension and postretirement benefits and lower administrative spending, driven by our continuous commitment to cost control efforts. With selling and administrative expenses decreasing 10% while our net sales decreased 3%, we reduced our selling and administrative expenses as a percentage of net sales to 10.8% in the first nine months of 2013 from 11.6% in the first nine months of 2012.

FINANCIAL CONDITION

Liquidity and Capital Resources

We believe that our operations will continue to generate cash and that sufficient cash, cash equivalents and borrowings under our Credit Facility will be available to fund operating needs, pay dividends, invest in the development of new products and filter media, fund planned capital expenditures, including the expansion of facilities, provide for interest and principal payments related to debt agreements, fund pension contributions and repurchase our common stock. We also continue to assess acquisition opportunities in related filtration businesses. Any such acquisitions could affect operating cash flows and require changes in our debt and capitalization. 

We had cash, cash equivalents and restricted cash of $216.6 million at the end of the third quarter of 2013.  Approximately $102.5 million of this cash was held at entities outside the U.S.  Although we plan to use this cash at our non-U.S. entities, if we repatriated this cash to the U.S., we could incur significant tax expense since most of this cash is considered permanently invested for U.S. tax purposes.  Cash and cash equivalents are held by financial institutions throughout the world.  We regularly review the credit worthiness of these institutions and believe our funds are not at significant risk.  

Our current ratio of 5.1 at the end of the third quarter of 2013 increased from 3.7 at year-end 2012.  This increase was primarily due to a $36.7 million reduction in accounts payable and accrued liabilities due in part to $24.3 million of pension benefit payments made in the first nine months of fiscal 2013, including $21.3 million related to pension benefits paid under our U.S. combined nonqualified pension plan to our former Executive Chairman who retired from the Company at the end of 2012, as well as a $5.1 million reduction in accrued incentive compensation from amounts paid in 2013 related to the 2012 company-wide profit sharing program, $4.0 million in payments made in fiscal 2013 related to the funding of matching contributions to the Company's defined contribution benefit plans and a $1.2 million reduction in trade accounts payable.

We entered into our Credit Facility in April 2012 under which we may borrow up to $150.0 million under a selection of currencies and rate formulas. Our Credit Facility also includes a $10.0 million swing line sub-facility and a $50.0 million letter of credit sub-facility, as well as an accordion feature that allows us to increase the Credit Facility by up to $100.0 million, subject to securing additional commitments from existing lenders or new lending institutions. We believe the financial institutions that are party to this arrangement have adequate capital resources and will be able to fund future borrowings under our Credit Facility.  At our election, the interest rate under our Credit Facility is based upon either a defined base rate or LIBOR plus an applicable margin.  Commitment fees and letter of credit fees are also payable under the Credit Facility. Borrowings under the Credit Facility are unsecured, but are guaranteed by substantially all of the Company's material domestic subsidiaries. The Credit Facility also contains certain covenants customary to such agreements, as well as customary events of default. At the end of the third quarter of 2013, the LIBOR interest rate on our Credit Facility including margin was 0.7%.  At the end of the third quarter of 2013, there were no borrowings outstanding on our Credit Facility, but we had approximately $16.0 million outstanding on a $50.0 million letter of credit sub-facility.  Accordingly, we had $134.0 million available for further borrowing at the end of the third quarter of 2013. Our Credit Facility expires in April 2017.

Total long-term debt of $16.7 million at the end of the third quarter of 2013 included $15.8 million outstanding on industrial revenue bonds and $0.9 million of other long-term debt.  At the end of the third quarter of 2013, we were in compliance with all financial covenants as included in our Credit Facility.  We expect to be in compliance with these covenants in the foreseeable future.  The ratio of total debt to total capitalization (defined as long-term debt plus total shareholders’ equity) was 1.7% at the end of the third quarter of 2013 compared to 1.8% at year-end 2012.

We had 49.7 million shares of common stock outstanding at the end of the third quarter of 2013, consistent with the amount outstanding at year-end 2012.  Shares issued pursuant to stock incentive plans were primarily offset by shares repurchased in the first nine months of 2013.  Shareholders’ equity increased to $977.3 million at the end of the third quarter of 2013 from $901.8 million at year-end 2012.  This $75.5 million increase resulted mainly from additional net earnings of $85.5 million and items related to stock compensation and option activity pursuant to incentive plans of $34.7 million, partially offset by dividend payments of $20.2 million, stock repurchases of $24.1 million and currency translation adjustments of $4.6 million.

Page 36

Cash Flow

Net cash provided by operating activities decreased $8.6 million to $71.2 million in the first nine months of 2013 from $79.8 million in the first nine months of 2012.  This decrease was primarily due to a $7.6 million increase in cash used for changes in working capital, which was driven primarily by a $21.5 million decrease in accounts payable, accrued liabilities and other liabilities and a $6.3 million increase in inventory, partly offset by improved accounts receivable management of $10.0 million and lower pension and postretirement healthcare liability payments of $12.7 million.

Net cash used in investing activities decreased $5.4 million in the first nine months of 2013 from the first nine months of 2012 primarily due to a $8.2 million decline in payments related to business acquisitions, a $4.0 million decline in capital expenditures and a $2.2 million increase in proceeds from disposition of plant assets, including the sale of our manufacturing facility in Jeffersontown, Kentucky which had been classified within assets held for sale. This was partially offset by a $9.1 million increase in restricted cash, driven by the staging of funds to execute the planned purchase of a European operating facility.

Net cash used in financing activities decreased $15.5 million in the first nine months of 2013 from the first nine months of 2012 primarily as the result of a $18.8 million increase in cash received from stock option exercises, the sale of capital stock pursuant to the Company's employee stock purchase plan and a $4.7 million increase in excess tax benefits from stock-based compensation, partially offset by a $7.4 million increase in cash paid for the repurchase of common stock and a $2.1 million increase in dividends paid.

We will continue to assess repurchases of our common stock. In June 2013, our Board of Directors authorized a $250.0 million stock repurchase program of our common stock in the open market and through private transactions over a three-year period. During the first nine months of 2013, we repurchased and retired 0.5 million shares of our common stock for $24.1 million at an approximate average price of $51.37.  At the end of the third quarter of 2013, there was approximately $244.8 million available for repurchase under the current authorization.  Future repurchases of our common stock may be made after considering cash flow requirements for internal growth, capital expenditures, acquisitions, interest rates and the market price of our common stock.

In January 2013 we announced that we intend to invest approximately $40.0 million in our Engine/Mobile Filtration segment to build a new warehouse and distribution center adjacent to our manufacturing facility in Kearney, Nebraska. The project is anticipated to take approximately two years to complete. Through the third quarter of 2013 we have incurred $0.6 million in costs related to this project.

During the first nine months of 2013 we made contributions of $21.3 million to our U.S. combined nonqualified pension plans related to pension benefits payable to our former Executive Chairman, who retired from the Company at the end of 2012.

At the end of the third quarter of 2013, our gross liability for uncertain income tax provisions was $2.0 million including interest and penalties.  Due to the high degree of uncertainty regarding the timing of potential future cash outflows associated with these liabilities, we were unable to make a reasonably reliable estimate of the amount and period in which these remaining liabilities might be paid.

Off-Balance Sheet Arrangements

Our off-balance sheet arrangements relate to various operating leases as discussed in Note H to the Consolidated Financial Statements in our 2012 Form 10-K.  We had no variable interest entity or special purpose entity agreements during the first nine months of 2013 or 2012.

OTHER MATTERS

Critical Accounting Policies

Our critical accounting policies, including the assumptions and judgments underlying them, are disclosed in our 2012 Form 10-K in Management’s Discussion and Analysis of Financial Condition and Results of Operations.  There have been no material changes in our critical accounting policies set forth in our 2012 Form 10-K.  These policies have been consistently applied in all material respects.  While the estimates and judgments associated with the application of these policies may be affected by different assumptions or conditions, we believe the estimates and judgments associated with the reported amounts are appropriate in the circumstances.

Environmental Matters and Climate Change and Energy Legislation and Regulation

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, we believe that any potential environmental liabilities 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 liabilities, costs or claims in the future, either under present laws and regulations or those that may be adopted or imposed in the future.

Foreign, federal, state and local regulatory and legislative bodies have proposed various legislative and regulatory measures relating to climate change, regulating greenhouse gas emissions and energy policies.  Due to the uncertainty in the regulatory and legislative processes, as well as the scope of such requirements and initiatives, we cannot currently determine the effect such legislation and regulation may have on our operations.

The potential physical impacts of climate change on our operations are also highly uncertain and would vary depending on type of physical impact and geographic location.  Climate change physical impacts could include changing temperatures, water shortages, changes in weather and rainfall patterns, and changing storm patterns and intensities.  The occurrence of one or more natural disasters, whether due to climate change or naturally occurring, such as tornadoes, hurricanes, earthquakes and other forms of severe weather in the U.S. or in a country in which we operate or in which our suppliers or customers are located could adversely impact our operations and financial performance.  Such events could result in:

• physical damage to and complete or partial closure of one or more of our manufacturing facilities

• temporary or long-term disruption in the supply of raw materials from our suppliers

• disruption in the transport of our products to customers and end users

• delay in the delivery of our products to our customers

Recent Relevant Accounting Pronouncements

A discussion of recent relevant accounting pronouncements is included in Note 1 to the Consolidated Condensed Financial Statements.

Commitments and Contingencies Disclosure [Abstract]

Contingencies

CONTINGENCIES

Legal Contingencies

From time to time, the Company is subject to lawsuits, investigations and disputes (some of which involve substantial claimed amounts) arising out of the conduct of its business, including matters relating to commercial transactions, product liability, intellectual property and other matters.  Items included in these other matters are discussed below.  The Company believes recorded reserves in its Consolidated Condensed Financial Statements are adequate in light of the probable and estimable outcomes of the items discussed below and other matters.  Any recorded liabilities were not material to the Company’s financial position, results of operation or liquidity and the Company does not currently believe that any pending claims or litigation, including those identified below, will materially affect its financial position, results of operations or liquidity.

TransWeb/3M

On May 21, 2010, 3M Company and 3M Innovative Properties (“3M”) brought a lawsuit against TransWeb, LLC ("TransWeb") in the United States District Court for the District of Minnesota, alleging that certain TransWeb products infringe multiple claims of certain 3M patents. Shortly after receiving service of process in this litigation, TransWeb filed its own complaint against 3M in the United States District Court for the District of New Jersey, seeking a declaratory judgment that the asserted patents are invalid and that the products in question do not infringe. 3M withdrew its Minnesota action, and the parties are currently litigating the matter in New Jersey.

The litigation in question was filed and underway before the Company acquired TransWeb in December 2010, but the Company assumed the risk of this litigation as a result of the acquisition. On June 3, 2011, TransWeb filed a Second Amended Complaint against 3M, (i) seeking declaratory judgment that the asserted 3M patents are invalid, the TransWeb products in question do not infringe, and the 3M patents are unenforceable due to inequitable conduct by 3M in obtaining the patents, (ii) alleging patent infringement by 3M of a patent held by TransWeb, and (iii) alleging antitrust violations by 3M in connection with certain upstream and downstream markets for fluorinated polymeric filtration media under theories of Walker Process fraud and sham litigation. TransWeb later dropped its patent infringement allegations against 3M, but continued to allege and pursue its inequitable conduct and antitrust claims. Prior to trial, 3M voluntarily dismissed with prejudice the majority of the patent claims 3M had originally brought against TransWeb, but continued to allege infringement by TransWeb of two claims of one of the patents in suit.

A jury trial commenced on November 13, 2012. After 10 days of testimony and deliberation, on November 30, 2012, a six-member jury unanimously found that (i) TransWeb does not infringe the asserted claims of the 3M patent in suit, (ii) the asserted claims of the patent in suit are invalid as being obvious, (iii) 3M violated the antitrust laws in trying to enforce patents obtained through fraud on the United States Patent Office (i.e., Walker Process fraud), (iv) TransWeb is entitled to recoup lost profits of approximately $34 plus its attorneys' fees as damages, and (v) 3M did not engage in "sham" litigation. The jury also rendered a unanimous advisory verdict, which is not binding on the court, that 3M's asserted patents were obtained through inequitable conduct, and thus unenforceable.

The court has not yet decided whether to accept the jury's verdict on inequitable conduct and has not yet issued a final judgment in the case, pending (i) resolution of various post-trial motions made by 3M to set aside the jury verdicts adverse to 3M, and (ii) a separate procedure before a third party Special Master to quantify and qualify TransWeb's attorneys' fees that may be awarded as damages, including those subject to potential trebling under the antitrust laws. Such procedure is anticipated to take until at least September 2013 to resolve.

The Company acquired TransWeb on December 29, 2010.  Of the base purchase price, the Company withheld payment of $17,000 pending resolution of the 3M litigation, which funds could be used by the Company in connection with the same.  Any litigation related amounts incurred in excess of the amount withheld would be expensed and paid by the Company. During the three months ended August 31, 2013, the Company did not apply any legal charges against the withheld payment as the limit had been reached. During the nine months endedAugust 31, 2013, the Company applied legal charges of $531 against the withheld payment.  Since the acquisition, the Company has incurred legal charges of $18,258 related to the 3M litigation, of which $17,000 has been applied against the withheld portion of the TransWeb purchase price as noted above. During the three and nine months endedAugust 31, 2013, the Company expensed $384 and $1,258, respectively, related to the 3M litigation, which is included in Selling and administrative expenses in the Consolidated Condensed Statements of Earnings.

Other

Additionally, the Company is party to various proceedings relating to environmental issues.  The U.S. Environmental Protection Agency and/or other responsible state agencies have designated the Company as a potentially responsible party, along with other companies, in remedial activities for the cleanup of waste sites under the Comprehensive Environmental Response, Compensation, and Liability Act (“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 is not material.  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 nature and extent of the contamination at issue, the length of time remediation may require, the complexity of the environmental regulation and the continuing advancement of remediation technology.  Applicable federal law may impose joint and several liability on each potentially responsible party for the cleanup.

In addition to the matters cited above, the Company is involved in legal actions arising in the normal course of business.  The Company records provisions with respect to identified claims or lawsuits when it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Claims and lawsuits are reviewed quarterly and provisions are taken or adjusted to reflect the status of a particular matter.

Other Contingencies

In the event of a change in control of the Company, termination benefits are likely to be required for certain executive officers and other employees.

Redeemable Noncontrolling Interests

In March 2007, the Company acquired an 80% ownership share in Sinfa SA (“SINFA”), a manufacturer of automotive and heavy-duty engine filters based in Casablanca, Morocco.  As part of the purchase agreement, the Company and the noncontrolling owners each have an option to require the purchase of the remaining 20% ownership shares by the Company after December 31, 2012 which would result in SINFA becoming a wholly owned subsidiary.  As of August 31, 2013, neither the Company nor the noncontrolling owners have exercised the purchase option. The remaining 20% of SINFA owned by the noncontrolling owners has been reported as Redeemable noncontrolling interests and classified as mezzanine equity in the Consolidated Condensed Balance Sheets.  The Redeemable noncontrolling interests is reflected at its carrying value, which is greater than its estimated redemption price. The Redeemable noncontrolling interests will be accreted to the redemption price, through equity, at the point at which the redemption becomes probable.  The Company has not recorded any accretion to date.

Earnings Per Share and Stock Repurchase Activity [Abstract]

Earnings Per Share and Stock Repurchase Activity

EARNINGS PER SHARE AND STOCK REPURCHASE ACTIVITY

The Company calculates basic earnings per share by dividing net earnings by the weighted average number of shares outstanding.  Diluted earnings per share reflects the impact of outstanding stock options, restricted stock and other stock-based arrangements.  The FASB has issued guidance requiring unvested share-based payment awards containing nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) be considered participating securities and included in the computation of earnings per share pursuant to the two-class method.  The Company’s unvested restricted stock unit awards discussed in Note 3 qualify as participating securities under this guidance.  However, the unvested restricted stock unit awards do not materially impact the calculation of basic or diluted earnings per share; therefore, the Company does not present the two-class method computation.  The following table provides a reconciliation of the numerators and denominators utilized in the calculation of basic and diluted earnings per share.

	Quarter Ended				Nine Months Ended
	August 31, 2013		September 1, 2012		August 31, 2013		September 1, 2012
Weighted average number of shares outstanding - Basic	50,092,548		50,283,340		49,917,939		50,357,567
Dilutive effect of stock-based arrangements	512,261		580,554		563,110		621,975
Weighted average number of shares outstanding - Diluted	50,604,809		50,863,894		50,481,049		50,979,542
Net earnings attributable to CLARCOR Inc.	$	28,707	$	30,270	$	85,220	$	86,676

BUSINESS ACQUISITIONS AND INVESTMENTS

Business Acquisitions

On May 9, 2012, the Company acquired 100% of the shares in Modular Engineering Company Pty Ltd. ("Modular") for $7,875. An initial payment of $5,237 was made at closing. On May 8, 2013, another installment of the purchase price in the amount of $1,530 was paid. The remaining purchase price will be paid on the second anniversary of the closing date. Modular, a manufacturer of pressure vessels, process and storage tanks and other natural gas filtration products and distributor of aftermarket elements is located in Henderson, Western Australia. The acquisition of Modular gave the Company first-fit manufacturing capabilities in Western Australia, as well as a platform for aftermarket growth throughout the region. Modular has been combined into an existing Company subsidiary, which is part of the Company's Industrial/Environmental Filtration segment. An allocation of the purchase price for the acquisition has been made to major categories of assets and liabilities. Acquired finite-lived intangible assets of $2,552 were recorded in connection with the purchase. The $5,339 excess of the initial purchase price over the estimated fair value of the assets acquired and liabilities assumed was recorded as goodwill, which is not deductible for income tax purposes. Net sales and Operating profit (loss) attributable to Modular for the three and nine months endedAugust 31, 2013 and September 1, 2012 were as follows:

	Quarter Ended					Nine Months Ended
	August 31, 2013			September 1, 2012		August 31, 2013			September 1, 2012

Investments

Effective May 1, 2008, the Company acquired a 30% share in BioProcessH2O LLC (“BPH”), a Rhode Island-based manufacturer of industrial waste water and water reuse filtration systems, for $4,000.  During the three and nine months endedAugust 31, 2013, the Company did not make any additional investments. During the three months ended September 1, 2012, the Company did not make any additional investments. During the nine months endedSeptember 1, 2012, the Company invested an additional $33. The Company also has $21 accrued which has not yet been funded and is included in Accounts payable and accrued liabilities in the accompanying Consolidated Condensed Balance Sheets at both August 31, 2013 and December 1, 2012. Under the terms of the agreement with BPH, the Company has the right, but not the obligation, to acquire additional ownership shares and eventually complete ownership of BPH over several years at a price based on, among other factors, BPH’s operating income.  The investment, with a carrying amount of $3,075 and $3,137, at August 31, 2013 and December 1, 2012, respectively, included in Other noncurrent assets in the Consolidated Condensed Balance Sheets, is being accounted for under the equity method of accounting.  The carrying amount is adjusted each period to recognize the Company’s share of the earnings or losses of BPH, included in Other, net in the Consolidated Condensed Statements of Earnings, based on the percentage of ownership, as well as the receipt of any dividends.  During the three and nine months endedAugust 31, 2013 and September 1, 2012, the Company did not receive any dividends from BPH.  The equity investment is periodically reviewed for indicators of impairment.

The Company also owns a 15.62% share in BioProcess Algae LLC (“Algae”), a Delaware-based company developing technology to grow and harvest algae which can be used to consume carbon dioxide and also be used as a renewable energy source.  During the three and nine months endedAugust 31, 2013, the Company invested an additional $156 and $615, respectively, into Algae, of which $223 had been accrued and included in Accounts payable and accrued liabilities at December 1, 2012 in the accompanying Consolidated Condensed Balance Sheets. During the three and nine months endedSeptember 1, 2012, the Company invested an additional $444 and $768, respectively, into Algae. The investment, with a carrying amount of $2,204 and $1,812 at August 31, 2013 and December 1, 2012, respectively, included in Other noncurrent assets, is being accounted for under the cost method of accounting.  Under the cost method, the Company recognizes dividends as income when received and reviews the cost basis of the investment for impairment if factors indicate that a decrease in value of the investment has occurred.  During the three and nine months endedAugust 31, 2013, the Company did not receive any dividends from Algae. During the three months ended September 1, 2012, the Company did not receive any dividends from Algae. During the nine months endedSeptember 1, 2012, the Company received dividends from Algae of $1,200, which is included in Other, net in the Consolidated Condensed Statements of Earnings.

Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill and Acquired Intangible Assets

GOODWILL AND ACQUIRED INTANGIBLE ASSETS

All goodwill is stated on a gross basis, as the Company has not recorded any impairment charges against goodwill. Based on a decline in the net sales of our TransWeb business, in the third quarter of 2013 we performed an impairment review of the related indefinite-lived intangible assets ($900 carrying value) and definite-lived intangible assets ($9,332 carrying value) and determined that the estimated future cash flows of the relevant asset group were sufficient to cover the carrying value and no impairment existed. We also performed an impairment review of goodwill at the related reporting unit, and determined that the estimated fair value of the reporting unit exceeds its book value and no impairment existed. Our analysis includes management judgment and estimates related to future cash flows, which we believe are reasonable. The following table reconciles the activity for goodwill by segment for the nine months endedAugust 31, 2013.  

	Engine/Mobile Filtration			Industrial/ Environmental Filtration			Packaging		Total

Incentive Plans and Stock-Based Compensation

INCENTIVE PLANS AND STOCK-BASED COMPENSATION

On March 23, 2009, the shareholders of CLARCOR approved the 2009 Incentive Plan, which replaced the 2004 Incentive Plan.  The 2009 Incentive Plan allows the Company to grant stock options, restricted stock unit awards, restricted stock, performance awards and other awards to officers, directors and key employees of up to 3,800,000 shares during a ten-year period that ends in December 2019.  Upon share option exercise or restricted stock unit award conversion, the Company issues new shares unless treasury shares are available.  The key provisions of the Company’s stock-based incentive plans are described in Note M of the Company’s Consolidated Financial Statements included in the 2012 Form 10-K.

Stock Options

Nonqualified stock options are granted at exercise prices equal to the market price of CLARCOR common stock at the date of grant, which is the date the Company’s Board of Directors approves the grant and the participants receive it.  The Company’s Board of Directors determines the vesting requirements for stock options at the time of grant and may accelerate vesting.  In general, options granted to key employees vest 25% per year beginning at the end of the first year; therefore, they become fully exercisable at the end of four years.  Vesting may be accelerated in the event of retirement, disability or death of a participant or change in control of the Company.  Options granted to non-employee directors vest immediately.  All options expire ten years from the date of grant unless otherwise terminated.

The following table summarizes information related to stock options and stock option exercises during the three and nine months endedAugust 31, 2013 and September 1, 2012.

The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model with the following weighted average assumptions by grant year.

	Nine Months Ended
	August 31, 2013			September 1, 2012
Weighted average fair value per option at the date of grant for options granted	$	9.98		$	12.49
Risk-free interest rate	1.19		%	1.38		%
Expected dividend yield	1.19		%	0.96		%
Expected volatility factor	25.80		%	26.52		%
Expected option term in years	5.4			6.1

The expected option term in years selected for options granted during each period presented represents the period of time that the options are expected to be outstanding based on historical data of option holder exercise and termination behavior.  Expected volatilities are based upon historical volatility of the Company’s monthly stock closing prices over a period equal to the expected life of each option grant.  The risk-free interest rate is selected based on yields from U.S. Treasury zero-coupon issues with a remaining term approximately equal to the expected term of the options being valued.  Expected dividend yield is based on the estimated dividend yield determined on the date of issuance.

Restricted Stock Unit Awards

The Company’s restricted stock unit awards are considered nonvested share awards.  The restricted stock unit awards require no payment from the employee.  Compensation cost is recorded based on the market price of the stock on the grant date and is recorded equally over the vesting period of four years.  During the vesting period, officers and key employees receive compensation equal to the amount of dividends declared on common shares they would have been entitled to receive had the shares been issued.  Upon vesting, employees may elect to defer receipt of their shares.  There were 14,760 and 131,197 vested and deferred shares at August 31, 2013 and December 1, 2012, respectively.

The following table summarizes information related to restricted stock unit awards during the three and nine months endedAugust 31, 2013 and September 1, 2012.

Long-Term Debt

LONG-TERM DEBT

On April 5, 2012, the Company entered into a five-year multicurrency revolving credit agreement (“Credit Facility”) with a group of financial institutions. Under the Credit Facility, the Company may borrow up to $150,000, which includes a $10,000 swing line sub-facility, as well as an accordion feature that allows the Company to increase the Credit Facility by a total of up to $100,000, subject to securing additional commitments from existing lenders or new lending institutions. At the Company's election, loans made under the Credit Facility bear interest at either (1) a defined base rate, which varies with the highest of the defined prime rate, the federal funds rate, or a specified margin over the one-month London Interbank Offered Rate (“LIBOR”), or (2) LIBOR plus an applicable margin. Swing line loans bear interest at the defined base rate plus an applicable margin. Commitment fees and letter of credit fees are also payable under the Credit Facility. Borrowings under the Credit Facility are unsecured, but are guaranteed by substantially all of the Company's material domestic subsidiaries. The Credit Facility also contains certain covenants customary to such agreements, as well as customary events of default. At August 31, 2013, there were no borrowings outstanding on the Credit Facility. The Credit Facility includes a $50,000 letter of credit sub-facility, against which $16,012 in letters of credit had been issued at both August 31, 2013 and December 1, 2012.

The Company has letters of credit totaling $28,573 and $23,307 as of August 31, 2013 and December 1, 2012, respectively, issued to various government agencies, primarily related to industrial revenue bonds, and to insurance companies and other commercial entities in support of its obligations. The Company believes that no payments will be required resulting from these obligations.

In the ordinary course of business, the Company also provides routine indemnifications and other guarantees whose terms range in duration and are often 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.

Warranties are recorded as a liability on the balance sheet and as charges to current expense for estimated normal warranty costs and, if applicable, for specific performance issues known to exist on products already sold. The expenses estimated to be incurred are provided at the time of sale and adjusted as needed, based primarily upon experience. Changes in the Company’s warranty accrual, which is included in Other accrued liabilities, are as follows:

INCOME TAXES

The following is a reconciliation of the beginning and ending amount of gross unrecognized tax benefits for uncertain tax positions, including positions which impact only the timing of tax benefits.

	Nine Months Ended
	August 31, 2013			September 1, 2012
Unrecognized tax benefits at beginning of year	$	2,209		$	3,015
Additions for current period tax positions	348			257

Reductions for lapse of statue of limitations / settlements	(334		)	(390		)
Changes in interest and penalties	(226		)	38
Unrecognized tax benefits at end of period	$	1,997		$	2,914

At August 31, 2013, the amount of unrecognized tax benefit, that would impact the effective tax rate if recognized, was $1,386.  The Company recognizes interest and penalties related to unrecognized benefits in income tax expense.  At August 31, 2013, the Company had $245 accrued for the payment of interest and penalties.

Due to the various jurisdictions in which the Company files tax returns and the uncertainty regarding the timing of settlements, it is possible that there could be other significant changes in the amount of unrecognized tax benefits in the next twelve months; however, the amount cannot be estimated.

The Company is regularly audited by federal, state and foreign tax authorities.  The Internal Revenue Service has completed its audits of the Company’s U.S. income tax returns through fiscal year 2009.  With few exceptions, the Company is no longer subject to income tax examinations by state or foreign tax jurisdictions for years prior to 2007.

During the nine months endedAugust 31, 2013, the Company recognized a $985 benefit related to the extension of the research and development tax credit in January 2013.

Fair Value Disclosures [Abstract]

Fair Value Measurements

FAIR VALUE MEASUREMENTS

Fair Value Measurements

The Company measures certain assets and liabilities at fair value as discussed throughout the notes to its quarterly and annual financial statements. Fair value is the exchange price that would be received for an asset or paid to transfer a liability, an exit price, in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants.  Fair value measurements are categorized in a hierarchy based upon the observability of inputs used in valuation techniques.  Observable inputs are the highest level and reflect market data obtained from independent sources, while unobservable inputs are the lowest level and reflect internally developed market assumptions.  The Company classifies fair value measurements by the following hierarchy:

• Level 1 – Quoted active market prices for identical assets

• Level 2 – Significant other observable inputs, such as quoted prices for similar (but not identical) instruments in active markets, quoted prices for identical or similar instruments in markets which are not active and model determined valuations in which all significant inputs or significant value-drivers are observable in active markets

• Level 3 – Significant unobservable inputs, such as model determined valuations in which one or more significant inputs or significant value-drivers are unobservable

Assets or liabilities that have recurring fair value measurements are shown below:

	Fair Value Measurements at Reporting Date

TransWeb contingent earn-out, included in Other long-term liabilities	$	1,292	$	—	$	—	$	1,292

There were no changes in the fair value determination methods or significant assumptions used in those methods during the nine months endedAugust 31, 2013.  There were no transfers between Level 1 and Level 2 and there were no transfers into or out of Level 3 during the nine months endedAugust 31, 2013. The Company's policy is to recognize transfers on the actual date of transfer. The restricted trust, which is used to fund certain payments for the Company’s U.S. combined nonqualified pension plans, consists of actively traded equity and bond funds. The TransWeb contingent earn-out payment was established in connection with the acquisition of TransWeb on December 29, 2010, and the acquisition-date estimated fair value of the earn-out payment to one of the former owners was $1,018.  The contingent liability for the earn-out payment will continue to be accounted for and measured at fair value until the contingency is settled during fiscal year 2016.  The fair value measurement of the contingent earn-out payment is based primarily on projected 2014 and 2015 TransWeb earnings, which represent significant inputs not observed in the market and thus represents a Level 3 measurement as defined by accounting literature. The contingent consideration payment is revalued to its current fair value at each reporting date.  Any increase or decrease in the fair value, as a result of changes in significant inputs such as the discount rate, the discount period or other factors used in the calculation, is recognized in Selling and administrative expenses in the Consolidated Condensed Statements of Earnings in the period the estimated fair value changes. The fair value of the contingent consideration was estimated using a probability-weighted discounted cash flow model with a discount rate of 13.2%. The fair value of the TransWeb contingent earn-out payment decreased by $1,292, based on changes in the projected earnings of TransWeb, during the nine months endedAugust 31, 2013.

Fair Values of Financial Instruments

The fair values of the Company’s financial instruments, which are cash and cash equivalents, restricted cash, accounts receivable, the restricted trust and accounts payable and accrued liabilities, approximated the carrying values of those financial instruments at both August 31, 2013 and December 1, 2012.  An expected present value technique is used to estimate the fair value of long-term debt.  Long-term debt had a fair value estimate of $16,570 and $16,532 at August 31, 2013 and December 1, 2012, respectively. The Company's fair value estimate of its long-term debt represents a Level 2 measurement as it is based on the current interest rates available to the Company for debt with similar remaining maturities.  The carrying value for the long-term debt at August 31, 2013 and December 1, 2012 is $16,693 and $16,592, respectively.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Consolidated Condensed Financial Statements

CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

Basis of Presentation

CLARCOR Inc. and its subsidiaries (collectively, the “Company” or “CLARCOR”) is a global provider of filtration products, filtration systems and services, and consumer and industrial packaging products. As discussed further in Note 13, the Company has three reportable segments: Engine/Mobile Filtration, Industrial/Environmental Filtration and Packaging. The Consolidated Condensed Financial Statements include all domestic and foreign subsidiaries that were more than 50% owned and controlled as of each respective reporting period presented. All intercompany accounts and transactions have been eliminated.

The Consolidated Condensed Statements of Earnings and the Consolidated Condensed Statements of Cash Flows for the periods ended August 31, 2013 and September 1, 2012 and the Consolidated Condensed Balance Sheet as of August 31, 2013 have been prepared by the Company without audit.  The Consolidated Condensed Financial Statements have been prepared on the same basis as those in the Company’s Annual Report on Form 10-K for the fiscal year ended December 1, 2012 (“2012 Form 10-K”).  The December 1, 2012 Consolidated Condensed Balance Sheet data was derived from the Company’s year-end audited Consolidated Financial Statements as presented in the 2012 Form 10-K but does not include all disclosures required by accounting principles generally accepted in the United States of America ("U.S. GAAP").  In the opinion of management, all adjustments (which include only normal recurring adjustments) necessary to present fairly the financial position, results of operations and cash flows have been made.  The results of operations for the period ended August 31, 2013, are not necessarily indicative of the operating results for the full year.  The information included in this Form 10-Q should be read in conjunction with the audited Consolidated Financial Statements and accompanying notes included in the 2012 Form 10-K.

Cash and Cash Equivalents and Restricted Cash

Highly liquid investments with an original maturity of three months or less when purchased and that are readily saleable are considered to be cash and cash equivalents.  Restricted cash represents funds held in escrow and cash balances held by German banks as collateral for certain guarantees of overseas subsidiaries.  Restricted cash classified as current corresponds to funds held in escrow that will be used within one year or guarantees that expire within one year.  The Company also has $1,883 and $1,839 of noncurrent restricted cash recorded in Other noncurrent assets as of August 31, 2013 and December 1, 2012, respectively, corresponding to guarantees and escrow agreements that expire longer than one year from the dates of the Consolidated Condensed Balance Sheets.

Inventories

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

	August 31, 2013		December 1, 2012
Raw materials	$	79,663	$	75,928
Work in process	36,839		34,996
Finished products	108,111		100,327
Inventories	$	224,613	$	211,251

Property, Plant and Equipment

At December 1, 2012, land of $398 and building and building fixtures of $1,602 related to one Kentucky plant were classified as Assets held for sale. Those assets where sold March 29, 2013 for $2,211 resulting in a gain of $211, which is included in Cost of sales in the accompanying Consolidated Condensed Statements of Earnings for the nine months ended August 31, 2013.

During the third quarter of 2013 the Company made the decision to dispose of certain equipment at our air filtration operations, resulting in a loss of $4,631, which is included in Cost of sales in the accompanying Consolidated Condensed Statements of Earnings for the nine months ended August 31, 2013.

Accumulated Other Comprehensive Loss

The components of the ending balances of Accumulated other comprehensive loss are as follows:

	August 31, 2013			December 1, 2012
Pension liability, net of tax	$	(46,338	)	$	(50,890	)
Translation adjustments, net of tax	(5,367		)	(818		)
Accumulated other comprehensive loss	$	(51,705	)	$	(51,708	)

New Accounting Guidance

In February 2013, the Financial Accounting Standards Board ("FASB") issued guidance to improve the reporting of reclassifications out of accumulated other comprehensive income ("AOCI"). The amendments do not change the current requirement for reporting net income or other comprehensive income in financial statements; however, the amendments require an entity to provide information about the amounts reclassified out of AOCI by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of AOCI by the respective line items of net income, but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail about those amounts. The guidance is effective for annual and interim periods beginning after December 15, 2012, although early adoption is permitted. The Company does not expect the adoption of this guidance on the first day of fiscal year 2014 to have a material impact on the Consolidated Financial Statements.

In July 2012, the FASB issued amendments to its indefinite-lived intangible assets impairment testing guidance to simplify how entities test for indefinite-lived intangible asset impairments. The objective of the amendments is to reduce cost and complexity by providing an entity with the option to make a qualitative assessment about the likelihood that an indefinite-lived intangible asset is impaired to determine whether it should perform a quantitative impairment test. The amendments also enhance the consistency of impairment testing guidance amount long-lived asset categories by permitting an entity to assess qualitative factors to determine whether it is necessary to calculate the asset's fair value when testing an indefinite-lived intangible asset for impairment, which is equivalent to the impairment testing requirements for other long-lived assets. The amendments are effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, although early adoption is permitted. The adoption of this guidance on the first day of fiscal year 2013 did not have a material impact on the Consolidated Financial Statements.

In September 2011, the FASB issued amendments to its goodwill impairment testing guidance to simplify how entities test for goodwill impairments. The amendments are intended to reduce complexity and cost by providing a company the option of making an initial qualitative evaluation about the likelihood of goodwill impairment in determining whether it should calculate the fair value of a reporting unit. The amendments also include examples of events and circumstances that a company should consider in evaluating whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. The amendments are effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011, although early adoption is permitted. The adoption of this guidance on the first day of fiscal year 2013 did not have a material impact on the Consolidated Financial Statements.

In June 2011, the FASB issued amendments to its comprehensive income guidance to (a) improve the comparability, consistency and transparency of financial reporting, (b) increase the prominence of items reported in other comprehensive income and (c) facilitate the convergence of U.S. GAAP with International Financial Reporting Standards ("IFRS"). The amendments require all non-owner changes in shareholders' equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The required amendments, pursuant to the guidance, must be applied retrospectively. In December 2011, the FASB issued amendments to defer certain presentation requirements of the initial guidance. The guidance is effective for fiscal years and interim periods within those years, beginning after December 15, 2011, although early adoption is permitted. The adoption of this guidance on the first day of fiscal year 2013 resulted in the presentation of the Consolidated Condensed Statements of Comprehensive Earnings, but did not have a material effect on the Company’s financial position or results of operations.

During the three and nine months ended August 31, 2013, the Company recorded a settlement cost of $3,111 related to the scheduled payment of pension benefits payable under our U.S. combined nonqualified pension plan to our former Executive Chairman, who retired from the Company at the end of 2012.

The Company’s policy is to contribute to its qualified U.S. and non-U.S. pension plans at least the minimum amount required by applicable laws and regulations, to contribute to the U.S. combined nonqualified plans when required for benefit payments, and to contribute to the postretirement healthcare benefit plan an amount equal to the benefit payments.  The Company, from time to time, makes voluntary contributions in excess of the minimum amount required as economic conditions warrant. The Company expects to contribute up to the following amounts to its various plans to pay benefits during 2013:

U.S. Qualified Plans	$	2,837
U.S. Combined Nonqualified Plans	21,335
Non-U.S. Plan	340

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Consolidation, Policy [Policy Text Block]

Basis of Presentation

CLARCOR Inc. and its subsidiaries (collectively, the “Company” or “CLARCOR”) is a global provider of filtration products, filtration systems and services, and consumer and industrial packaging products. As discussed further in Note 13, the Company has three reportable segments: Engine/Mobile Filtration, Industrial/Environmental Filtration and Packaging. The Consolidated Condensed Financial Statements include all domestic and foreign subsidiaries that were more than 50% owned and controlled as of each respective reporting period presented. All intercompany accounts and transactions have been eliminated.

The Consolidated Condensed Statements of Earnings and the Consolidated Condensed Statements of Cash Flows for the periods ended August 31, 2013 and September 1, 2012 and the Consolidated Condensed Balance Sheet as of August 31, 2013 have been prepared by the Company without audit.  The Consolidated Condensed Financial Statements have been prepared on the same basis as those in the Company’s Annual Report on Form 10-K for the fiscal year ended December 1, 2012 (“2012 Form 10-K”).  The December 1, 2012 Consolidated Condensed Balance Sheet data was derived from the Company’s year-end audited Consolidated Financial Statements as presented in the 2012 Form 10-K but does not include all disclosures required by accounting principles generally accepted in the United States of America ("U.S. GAAP").  In the opinion of management, all adjustments (which include only normal recurring adjustments) necessary to present fairly the financial position, results of operations and cash flows have been made.  The results of operations for the period ended August 31, 2013, are not necessarily indicative of the operating results for the full year.  The information included in this Form 10-Q should be read in conjunction with the audited Consolidated Financial Statements and accompanying notes included in the 2012 Form 10-K.

Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block]

Cash and Cash Equivalents and Restricted Cash

Highly liquid investments with an original maturity of three months or less when purchased and that are readily saleable are considered to be cash and cash equivalents.  Restricted cash represents funds held in escrow and cash balances held by German banks as collateral for certain guarantees of overseas subsidiaries.  Restricted cash classified as current corresponds to funds held in escrow that will be used within one year or guarantees that expire within one year.

Inventory, Policy [Policy Text Block]

Inventories

Inventories are valued at the lower of cost or market primarily determined on the first-in, first-out (“FIFO”) method of inventory costing, which approximates current cost.

New Accounting Guidance [Table Text Block]

New Accounting Guidance

In February 2013, the Financial Accounting Standards Board ("FASB") issued guidance to improve the reporting of reclassifications out of accumulated other comprehensive income ("AOCI"). The amendments do not change the current requirement for reporting net income or other comprehensive income in financial statements; however, the amendments require an entity to provide information about the amounts reclassified out of AOCI by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of AOCI by the respective line items of net income, but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail about those amounts. The guidance is effective for annual and interim periods beginning after December 15, 2012, although early adoption is permitted. The Company does not expect the adoption of this guidance on the first day of fiscal year 2014 to have a material impact on the Consolidated Financial Statements.

In July 2012, the FASB issued amendments to its indefinite-lived intangible assets impairment testing guidance to simplify how entities test for indefinite-lived intangible asset impairments. The objective of the amendments is to reduce cost and complexity by providing an entity with the option to make a qualitative assessment about the likelihood that an indefinite-lived intangible asset is impaired to determine whether it should perform a quantitative impairment test. The amendments also enhance the consistency of impairment testing guidance amount long-lived asset categories by permitting an entity to assess qualitative factors to determine whether it is necessary to calculate the asset's fair value when testing an indefinite-lived intangible asset for impairment, which is equivalent to the impairment testing requirements for other long-lived assets. The amendments are effective for annual and interim impairment tests performed for fiscal years beginning after September 15, 2012, although early adoption is permitted. The adoption of this guidance on the first day of fiscal year 2013 did not have a material impact on the Consolidated Financial Statements.

In September 2011, the FASB issued amendments to its goodwill impairment testing guidance to simplify how entities test for goodwill impairments. The amendments are intended to reduce complexity and cost by providing a company the option of making an initial qualitative evaluation about the likelihood of goodwill impairment in determining whether it should calculate the fair value of a reporting unit. The amendments also include examples of events and circumstances that a company should consider in evaluating whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. The amendments are effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011, although early adoption is permitted. The adoption of this guidance on the first day of fiscal year 2013 did not have a material impact on the Consolidated Financial Statements.

In June 2011, the FASB issued amendments to its comprehensive income guidance to (a) improve the comparability, consistency and transparency of financial reporting, (b) increase the prominence of items reported in other comprehensive income and (c) facilitate the convergence of U.S. GAAP with International Financial Reporting Standards ("IFRS"). The amendments require all non-owner changes in shareholders' equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The required amendments, pursuant to the guidance, must be applied retrospectively. In December 2011, the FASB issued amendments to defer certain presentation requirements of the initial guidance. The guidance is effective for fiscal years and interim periods within those years, beginning after December 15, 2011, although early adoption is permitted. The adoption of this guidance on the first day of fiscal year 2013 resulted in the presentation of the Consolidated Condensed Statements of Comprehensive Earnings, but did not have a material effect on the Company’s financial position or results of operations.
