Summary Of Significant Accounting Policies	'
	NOTE A  Summary of Significant Accounting Policies
	Description of Business Donaldson Company, Inc. (Donaldson or the Company), is a worldwide manufacturer of filtration systems and replacement parts.  The Company’s core strengths are leading filtration technology, strong Customer relationships, and its global presence.  Products are manufactured at 39 plants around the world and through three joint ventures.  Products are sold to original equipment manufacturers (OEMs), distributors, dealers, and directly to end-users.
	Principles of Consolidation The Consolidated Financial Statements include the accounts of Donaldson Company, Inc. and all majority-owned subsidiaries.  All intercompany accounts and transactions have been eliminated.  The Company’s three joint ventures that are not majority-owned are accounted for under the equity method.
	Use of Estimates The preparation of Financial Statements in conformity with generally accepted accounting principles in the United States of America (U.S.) (U.S. GAAP) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes.  Actual results could differ from those estimates.
	Foreign Currency Translation For substantially all foreign operations, local currencies are considered the functional currency.  Assets and liabilities of non-U.S. dollar functional currency entities are translated to U.S. dollars at year-end exchange rates and the resulting gains and losses arising from the translation of net assets located outside the U.S. are recorded as a cumulative translation adjustment, a component of Accumulated other comprehensive income (loss) (AOCI) in the Consolidated Balance Sheets.  Elements of the Consolidated Statements of Earnings are translated at average exchange rates in effect during the year.  Realized and unrealized foreign currency transaction gains and losses are included in Other income, net in the Consolidated Statements of Earnings.  Foreign currency translation gains of $1.7 million, $0.2 million, and $1.8 million are included in Other income, net in the Consolidated Statements of Earnings in Fiscal 2014, 2013, and 2012, respectively.
	Cash Equivalents The Company considers all highly liquid temporary investments with an original maturity of three months or less to be cash equivalents.  Cash equivalents are carried at cost that approximates market value.
	Short-Term Investments As of July 31, 2014 and 2013, the Company’s short-term investments consisted exclusively of time deposits with durations longer than 3 months, but less than 1 year.  These investments are carried at cost, which approximates their estimated fair value.  Classification of the Company’s investments as current or non-current is dependent upon management’s intended holding period, the investment’s maturity date, and liquidity considerations based on market conditions.  If management intends to hold the investments for longer than one year as of the balance sheet date, they are classified as non-current.
	Accounts Receivable and Allowance for Doubtful Accounts Trade accounts receivable are recorded at the invoiced amount and do not bear interest.  The allowance for doubtful accounts is the Company’s best estimate of the amount of credit losses in its existing accounts receivable.  The Company determines the allowance based on historical write-off experience in the industry, regional economic data, and evaluation of specific Customer accounts for risk of loss.  The Company reviews its allowance for doubtful accounts monthly.  Past due balances over 90 days and over a specified amount are reviewed individually for collectability.  All other balances are reviewed on a pooled basis by type of receivable.  Account balances are charged off against the allowance when the Company feels it is probable the receivable will not be recovered.  The Company does not have any off-balance-sheet credit exposure related to its Customers.
	Inventories Inventories are stated at the lower of cost or market.  U.S. inventories are valued using the last-in, first-out (LIFO) method, while the non-U.S. inventories are valued using the first-in, first-out (FIFO) method.  Inventories valued at LIFO were approximately 33 percent of total inventories at July 31, 2014 and 2013.  For inventories valued under the LIFO method, the FIFO cost exceeded the LIFO carrying values by $37.9 million and $37.8 million at July 31, 2014 and 2013, respectively.  Results of operations for all periods presented were not materially affected by the liquidation of LIFO inventory.  The components of inventory are as follows (thousands of dollars):
		At July 31,
		2014		2013
	Raw materials	$	112,522	$	99,814
	Work in process		17,256		29,097
	Finished products		123,573		105,909
	Total inventories	$	253,351	$	234,820
	Property, Plant, and Equipment Property, plant, and equipment are stated at cost.  Additions, improvements, or major renewals are capitalized, while expenditures that do not enhance or extend the asset’s useful life are charged to expense as incurred.  Depreciation is computed under the straight-line method.  Depreciation expense was $62.0 million in Fiscal 2014, $58.8 million in Fiscal 2013, and $55.3 million in Fiscal 2012.  The estimated useful lives of property, plant, and equipment are 10 to 40 years for buildings, including building improvements, and 3 to 10 years for machinery and equipment.  The components of property, plant, and equipment are as follows (thousands of dollars):
		At July 31,
		2014		2013
	Land	$	20,558	$	21,116
	Buildings		273,599		270,022
	Machinery and equipment		753,637		687,797
	Construction in progress		51,394		46,078
	Less accumulated depreciation		-647,523		-605,733
	Total property, plant, and equipment, net	$	451,665	$	419,280
	Internal-Use Software The Company capitalizes direct costs of materials and services used in the development and purchase of internal-use software.  Amounts capitalized are amortized on a straight-line basis over a period of five to seven years and are reported as a component of machinery and equipment within property, plant, and equipment.
	Goodwill and Other Intangible Assets Goodwill represents the excess of the purchase price over the fair value of net assets acquired in business combinations under the purchase method of accounting.  Other intangible assets, consisting primarily of patents, trademarks, and Customer relationships and lists, are recorded at cost and are amortized on a straight-line basis over their estimated useful lives of 3 to 20 years.  Goodwill is assessed for impairment annually or if an event occurs or circumstances change that would indicate the carrying amount may be impaired.  The impairment assessment for goodwill is done at a reporting unit level.  Reporting units are one level below the operating segment level, but can be combined when reporting units within the same operating segment have similar economic characteristics.  An impairment loss generally would be recognized when the carrying amount of the reporting unit’s net assets exceeds the estimated fair value of the reporting unit.
	Recoverability of Long-Lived Assets The Company reviews its long-lived assets, including identifiable intangibles, for impairment when events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.  If impairment indicators are present and the estimated future undiscounted cash flows are less than the carrying value of the assets, the carrying value is reduced.  There were no significant impairment charges recorded in Fiscal 2014, Fiscal 2013, or Fiscal 2012.
	Income Taxes The provision for income taxes is computed based on the pre-tax income reported for financial statement purposes.  Deferred tax assets and liabilities are recognized for the expected future tax consequences attributed to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis.  Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to reverse.  Valuation allowances are recorded to reduce deferred tax assets when it is more-likely-than-not that a tax benefit will not be realized.
	Comprehensive Income (Loss) Comprehensive income (loss) consists of net income, foreign currency translation adjustments, net changes in the funded status of pension retirement obligations, and net gains or losses on cash flow hedging derivatives, and is presented in the Consolidated Statements of Changes in Shareholders’ Equity.  The components of the ending balances of AOCI are as follows (thousands of dollars):
		At July 31,
		2014		2013		2012
	Foreign currency translation adjustment	$	48,289	$	50,411	$	32,976
	Net loss on cash flow hedging derivatives, net of deferred taxes		-101		-172		-292
	Pension and postretirement liability adjustment, net of deferred taxes		-93,998		-87,712		-134,572
	Total accumulated other comprehensive loss	$	-45,810	$	-37,473	$	-101,888
	Cumulative foreign currency translation is not adjusted for income taxes.  See Note H for additional disclosures related to AOCI.
	Earnings Per Share The Company’s basic net earnings per share are computed by dividing net earnings by the weighted average number of outstanding common shares.  The Company’s diluted net earnings per share is computed by dividing net earnings by the weighted average number of outstanding common shares and common equivalent shares relating to stock options and stock incentive plans.  Certain outstanding options were excluded from the diluted net earnings per share calculations because their exercise prices were greater than the average market price of the Company’s common stock during those periods.  There were 884,138 options, 22,619 options, and 1,063,135 options excluded from the diluted net earnings per share calculation for the fiscal year ended July 31, 2014, 2013, and 2012, respectively.
	The following table presents information necessary to calculate basic and diluted earnings per share:

	On January 27, 2012, the Company announced that its Board of Directors declared a two-for-one stock split effected in the form of a 100 percent stock dividend. The stock split was distributed March 23, 2012, to stockholders of record as of March 2, 2012.  Earnings and dividends per share and weighted average shares outstanding are presented in this Form 10-K after the effect of the 100 percent stock dividend.  The two-for-one stock split is reflected in the share amounts in all periods presented in the table above and elsewhere in this annual Form 10-K.
	Treasury Stock Repurchased common stock is stated at cost (determined on an average cost basis) and is presented as a reduction of shareholders’ equity.
	Research and Development Research and development costs are charged against earnings in the year incurred.  Research and development expenses include basic scientific research and the application of scientific advances to the development of new and improved products and their uses.
	Stock-Based Compensation The Company offers stock-based employee compensation plans, which are more fully described in Note I.  Stock-based employee compensation cost is recognized using the fair-value based method.
	Revenue Recognition Revenue is recognized when all the following criteria are satisfied: (a) persuasive evidence of a sales arrangement exists; (b) price is fixed and determinable; (c) collectability is reasonably assured; and (d) delivery has occurred.  At that time, product ownership and the risk of loss have transferred to the Customer and the Company has no remaining obligations.  The Company records estimated discounts and rebates as a reduction of sales in the same period revenue is recognized.  Shipping and handling costs for Fiscal 2014, 2013, and 2012 totaled $64.2 million, $66.2 million, and $67.0 million, respectively, and are classified as a component of selling, general, and administrative expenses.
	Product Warranties The Company provides for estimated warranty costs at the time of sale and accrues for specific items at the time their existence is known and the amounts are determinable.  The Company estimates warranty costs using standard quantitative measures based on historical warranty claim experience and evaluation of specific Customer warranty issues.  For a warranty reserve reconciliation see Note M.
	Derivative Instruments and Hedging Activities The Company recognizes all derivatives on the balance sheet at fair value.  Derivatives that are not designated as hedges are adjusted to fair value through income.  If the derivative is designated as a hedge, depending on the nature of the hedge, changes in the fair value of derivatives are either offset against the change in fair value of the hedged assets, liabilities, or firm commitments through earnings or recognized in shareholders’ equity through other comprehensive income until the hedged item is recognized.  Gains or losses related to the ineffective portion of any hedge are recognized through earnings in the current period.
	New Accounting Standards Recently Adopted In February 2013, the FASB updated the disclosure requirements for AOCI.  The updated guidance requires companies to disclose amounts reclassified out of AOCI by component.  The updated guidance only impacts disclosure requirements and does not affect how net income or other comprehensive income are calculated.  The updated guidance was adopted by the Company beginning in the first quarter of Fiscal 2014.  For additional information, refer to Note H.

Fair Value [Abstract]	'
Fair Value	'
	NOTE E  Fair Value
	Fair Value of Financial Instruments At July 31, 2014 and 2013, the Company’s financial instruments included cash and cash equivalents, accounts receivable, accounts payable, short-term borrowings, long-term debt, and derivative contracts.  The fair values of cash and cash equivalents, accounts receivable, accounts payable, and short-term borrowings approximated carrying values because of the short-term nature of these instruments and are classified as Level 1 in the fair value hierarchy.  Derivative contracts are reported at their fair values based on third-party quotes.  As of July 31, 2014, the estimated fair value of long-term debt with fixed interest rates was $237.6 million compared to its carrying value of $225.0 million.  The fair value is estimated by discounting the projected cash flows using the rate that similar amounts of debt could currently be borrowed, which is classified as Level 2 in the fair value hierarchy.
	Derivative contracts are reported at their fair values based on third-party quotes.  The fair values of the Company’s financial assets and liabilities listed below reflect the amounts that would be received to sell the assets or paid to transfer the liabilities in an orderly transaction between market participants at the measurement date (exit price).  The fair values are based on inputs other than quoted prices that are observable for the asset or liability.  These inputs include foreign currency exchange rates and interest rates.  The financial assets and liabilities are primarily valued using standard calculations and models that use as their basis readily observable market parameters.  Industry standard data providers are the primary source for forward and spot rate information for both interest rates and currency rates.
	The following summarizes the Company’s fair value of outstanding derivatives at July 31, 2014, and 2013, on the Consolidated Balance Sheets:
		Significant Other Observable Inputs
		(Level 2)*
		At July 31,
		2014		2013

	Asset derivatives recorded under the caption Prepaids and other current assets
	Foreign exchange contracts	$	931	$	734
	Liability derivatives recorded under the caption Other current liabilities
	Foreign exchange contracts		-1,242		-845
	Forward exchange contracts - net liability position	$	-311	$	-111
	*Inputs to the valuation methodology of level 2 assets include quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in inactive markets; inputs other than quoted prices that are observable for the asset or liability; and inputs that are derived principally from or corroborated by observable market data by correlation or other means.
	The Company holds equity method investments which are classified in other long-term assets in the consolidated balance sheets.  The aggregate carrying amount of these investments was $21.4 million and $18.8 million as of July 31, 2014 and 2013, respectively.  These equity method investments are measured at fair value on a nonrecurring basis.  The fair value of the Company’s equity method investments has not been estimated as there have been no identified events or changes in circumstance that would have had an adverse impact on the value of these investments.  In the event that these investments were required to be measured, these investments would fall within Level 3 of the fair value hierarchy, due to the use of significant unobservable inputs to determine fair value, as the investments are in privately-held entities or divisions of public companies without quoted market prices.
	Goodwill and intangible assets are assessed for impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired.  The Company’s goodwill and intangible assets are not recorded at fair value as there have been no events or circumstances that would have an adverse impact on the value of these assets.  In the event that an impairment was recognized, the fair value would be classified within Level 3 of the fair value hierarchy.  Refer to Note B for further discussion of the annual goodwill impairment analysis and carrying values of goodwill and other intangible assets.
	The Company assesses the impairment of intangible assets and property, plant, and equipment whenever events or changes in circumstances indicate that the carrying amount of property, plant, and equipment assets may not be recoverable.  There were no significant impairment charges recorded in Fiscal 2014, Fiscal 2013, or Fiscal 2012.  Refer to Note B for further discussion of the annual goodwill impairment analysis and carrying values of intangible assets.

Employee Benefit Plans	'
	NOTE F  Employee Benefit Plans
	Pension Plans The Company and certain of its international subsidiaries have defined benefit pension plans for many of their hourly and salaried employees.  There are two types of U.S. plans.  The first type of U.S. plan is a traditional defined benefit pension plan primarily for production employees.  The second is a plan for salaried workers that provides defined benefits pursuant to a cash balance feature whereby a participant accumulates a benefit comprised of a percentage of current salary that varies with years of service, interest credits and transition credits.  The non-U.S. plans generally provide pension benefits based on years of service and compensation level.
	On July 31, 2013, the Company adopted a sunset freeze on its U.S. salaried pension plan.  Effective August 1, 2013, there are no longer any new entrants into the plan.  Then effective, August 1, 2016, employees hired prior to August 1, 2013, will no longer continue to accrue Company contribution credits under the plan.

	AOCI at July 31, 2014 consists primarily of unrecognized actuarial losses, net of tax.  The loss expected to be recognized in net periodic pension expense during Fiscal 2015 is $7.6 million.  The accumulated benefit obligation for all defined benefit pension plans was $476.1 million and $427.8 million at July 31, 2014 and 2013, respectively.
	The projected benefit obligation, accumulated benefit obligation, and fair value of plan assets for pension plans with accumulated benefit obligations in excess of plan assets were $234.8 million, $233.8 million, and $215.9 million, respectively, as of July 31, 2014, and $20.5 million, $19.7 million, and $8.4 million, respectively, as of July 31, 2013.
	For the years ended July 31, 2014 and 2013, the U.S. pension plans represented approximately 69 percent and 70 percent, respectively, of the Company’s total plan assets, approximately 69 percent and 71 percent, respectively, of the Company’s total projected benefit obligation, and approximately 80 percent and 75 percent, respectively, of the Company’s total pension expense.
	The weighted-average discount rate and rates of increase in future compensation levels used in determining the actuarial present value of the projected benefit obligation are as follows:
	Weighted average actuarial assumptions		2014		2013
	All U.S. plans:
	Discount rate		4.33%		4.58%
	Rate of compensation increase		2.61%		2.61%
	Non - U.S. plans:
	Discount rate		3.64%		4.04%
	Rate of compensation increase		2.79%		2.92%
	The weighted-average discount rates, expected returns on plan assets and rates of increase in future compensation levels used to determine the net periodic benefit cost are as follows:
	Weighted average actuarial assumptions		2014		2013		2012
	All U.S. plans:
	Discount rate		4.58%		3.59%		4.91%
	Expected return on plan assets		7.50%		7.50%		7.75%
	Rate of compensation increase		2.61%		2.61%		4.50%
	Non - U.S. plans:
	Discount rate		4.04%		4.13%		5.36%
	Expected return on plan assets		5.48%		5.20%		6.03%
Rate of compensation increase		2.92%		2.86%		3.57%
Expected Long-Term Rate of Return To develop the expected long-term rate of return on assets assumption, the Company considered the historical returns and the future expectations for returns for each asset class, as well as the target asset allocation of the pension portfolio.  In Fiscal 2014 the Company adopted a plan to adjust the target asset allocation for all U.S. plans and to employ differing allocation strategies for each plan.  These investment changes, which will be implemented in the first quarter of Fiscal 2015, will help the Company to maintain or reduce the risk profile while continuing to ensure an appropriate funded status in each plan.  Therefore, as of the measurement date of July 31, 2014, the Company reduced its long-term rate of return for the U.S. pension plans to an asset-based weighted average of 7.14 percent.  The expected long-term rate of return on assets shown in the pension benefit disclosure for non-U.S. plans is an asset-based weighted average of all non-U.S. plans.
Discount Rate The Company’s objective in selecting a discount rate is to select the best estimate of the rate at which the benefit obligations could be effectively settled on the measurement date, taking into account the nature and duration of the benefit obligations of the plan.  In making this best estimate, the Company looks at rates of return on high-quality fixed-income investments currently available, and expected to be available, during the period to maturity of the benefits.  This process includes looking at the universe of bonds available on the measurement date with a quality rating of Aa or better. Similar appropriate benchmarks are used to determine the discount rate for the non-U.S. plans. The discount rate disclosed in the assumptions used to determine net periodic benefit cost and to determine benefit obligations is based upon a weighted average, using year-end projected benefit obligations.
Plan Assets The Company used the following definitions to classify pension assets into either Level 1, Level 2, or Level 3:
Level 1 – Quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.
Level 2 – Inputs other than quoted prices available in Level 1 that are observable either directly or indirectly.
Level 3 – Unobservable inputs for the asset or liability.
The fair values of the assets held by the U.S. pension plans by asset category are as follows (in millions):
		Quoted Prices in
		Active Markets			Significant			Significant
		for Identical			Observable			Unobservable
		Assets			Inputs			Inputs

Global Equity consists primarily of publicly traded U.S. and non-U.S. equities, Europe, Australasia, Far East (EAFE) index funds, equity private placement funds, private equity investments, and some cash and cash equivalents.  Publicly traded equities are valued at the closing price reported in the active market in which the individual securities are traded.  Index funds are valued at the net asset value (NAV) as determined by the custodian of the fund.  The NAV is based on the fair value of the underlying assets owned by the fund, minus its liabilities then divided by the number of units outstanding.  Private equity consists of interests in partnerships that invest in U.S. and non-U.S. equity and debt securities.  This may include a diversified mix of partnership interests including buyouts, restructured/distressed debt, growth equity, mezzanine/subordinated debt, real estate, special situation partnerships, and venture capital investments.  Partnership interest is valued using the most recent general partner statement of fair value, updated for any subsequent partnership interests' cash flow.
The target allocation for Global Equity investments was  65 percent.  The underlying global equity investment managers within the Plan will invest primarily in equity securities spanning across market capitalization, geography, style (value, growth), and other diversifying characteristics.  Managers may invest in common stocks or American Depository Receipts (ADRs), mutual funds, bank or trust company pooled funds, international stocks, stock options for hedging purposes, stock index futures, financial futures for purposes of replicating a major market index, and private equity partnerships.  The Long/Short Equity managers within Global Equity may take long or short positions in equity securities and have the ability to shift exposure from net long to net short.  Long/Short Equity managers made up about 15 percent of the global equity portfolio at year-end, and are considered less liquid, as the funds can be partially liquidated on a quarterly basis.  Long-only managers are considered liquid.  The long-only investment managers are typically valued daily, while long/short equity is valued on a monthly basis.  Private equity is considered illiquid and performance is typically valued on a quarterly basis.  The underlying assets, however, may be valued less frequently, such as annually, or if and when a potential buyer is identified and has submitted a bid to similar types of investments.
Fixed income consists primarily of investment and non-investment grade debt securities and alternative fixed income-like investments.  Corporate and other bonds and notes are valued at either the yields currently available on comparable securities of issuers with similar credit ratings or valued under a discounted cash flows approach that maximizes observable inputs, such as current yields of similar instruments, but includes adjustments for certain risks that may not be observable such as credit and liquidity risks.  Alternative fixed income-like investments consist primarily of private partnership interests in hedge funds of funds.  Partnership interests are valued using the NAV as determined by the administrator or custodian of the fund.
The target allocation for Fixed Income was  30 percent.  The Fixed Income class may invest in Debt securities issued or guaranteed by the U.S., its agencies or instrumentalities (including U.S. Government Agency mortgage backed securities), or other investment grade rated debt issued by foreign governments; corporate bonds, debentures and other forms of corporate debt obligations, including equipment trust certificates; Indexed notes, floaters and other variable rate obligations; bank collective funds; mutual funds; insurance company pooled funds and guaranteed investments; futures and options for the purpose of yield curve management; and private debt investments.  Fixed Income risk is driven by various factors including, but not limited to,  interest rate levels and changes, credit risk, and duration. The current fixed income investment is considered liquid, with daily pricing and liquidity.  The Fixed Income class is also invested in a variety of alternative investments.  Alternatives cover an enormous variety of traditional and non-traditional investments and investment strategies, spanning various levels of risk and return.  These investments can be made in a broad array of non-traditional investment strategies (including, but not limited to, commodities and futures, distressed securities, short/long--or both--fixed income, international opportunities, relative value) with multiple hedge fund managers.   This class is considered less liquid to illiquid.  The liquidity ranges from quarterly to semi-annually and illiquid.  Alternative investments are typically valued on a quarterly basis.
Real assets consist of commodity funds, Real Estate Investment Trusts (REITS), and interests in partnerships that invest in private real estate, commodity, and timber investments.  Private investments are valued using the most recent partnership statement of fair value, updated for any subsequent partnership interests' cash flows.  Commodity funds and REITS are valued at the closing price reported in the active market in which it is traded.
The target allocation for Real Assets was  5 percent.  The Fund invests in real assets to provide a hedge against unexpected inflation, to capture unique sources of returns, and to provide diversification benefits.  The Fund pursues a real asset strategy through a fund of funds, private investments, and/or a direct investment program that may invest long, short, or both in assets including, but not limited to, domestic and international properties, buildings and developments, timber, and/or commodities.  Real assets range from less liquid to illiquid, with about two-thirds of the real asset allocation having monthly liquidity and one-third illiquid.  Real asset manager performance is typically reported quarterly, though underlying assets may be valued less frequently.
Reflecting the relatively long-term nature of the plans’ obligations, approximately 65 percent of the plans assets are invested in equity securities, 30 percent in fixed income, and 5 percent in real assets (investments into funds containing commodities and real estate).  In Fiscal 2015, the Company plans to begin investing in liability-driven investment funds, which will change the asset allocations.

Global equity consists of publicly traded diversified growth funds invested across a broad range of traditional and alternative asset classes which may include, but are not limited to, equities, investment grade and high yield bonds, property, private equity, infrastructure, commodities and currencies.  They may invest directly or hold up to 100 percent of the fund in other collective investment vehicles and may use exchange traded and over the counter financial derivatives, such as currency forwards or futures, for both investment as well as hedging purposes.
Fixed income consists primarily of investment grade debt securities.  Corporate bonds and notes are valued at either the yields currently available on comparable securities of issuers with similar credit ratings or valued under a discounted cash flows approach that maximizes observable inputs, such as current yields of similar instruments, but includes adjustments for certain risks that may not be observable such as credit and liquidity risks.  These funds may also aim to provide liability hedging by offering interest rate and inflation protections which replicates the liability profile of a typical defined benefit pension scheme.
Equity/Fixed Income consists of Level 1 assets that are part of a unit linked fund with a strategic asset allocation of 40 percent fixed income products and 60 percent equity type products.  Assets are valued at either the closing price reported if traded on an active market or at yields currently available on comparable securities of issuers with similar credit ratings.  Index funds are valued at the net asset value as determined by the custodian of the fund.  The Level 3 assets are composed of mathematical reserves on individual contracts and the Company does not have any influence on the investment decisions as made by the insurer due to the specific minimum guaranteed return characteristics of this type of contract.  European insurers in general, broadly have a strategic asset allocation with 80 percent to 90 percent fixed income products and 20 percent to 10 percent equity type products (including real estate).
Real Assets consists of property funds.  Property funds are valued using the most recent partnership statement of fair value, updated for any subsequent partnership interests’ cash flows.

Investment Policies and Strategies. For the Company’s U.S. plans, the Company uses a total return investment approach to achieve a long-term return on plan assets, with what the Company believes to be a prudent level of risk for the purpose of meeting its retirement income commitments to employees. The plans’ investments are diversified to assist in managing risk. In Fiscal 2014, the Company’s asset allocation guidelines targeted an allocation of 65 percent global equity securities, 30 percent fixed income, and 5 percent real assets (investments into funds containing commodities and real estate).  These target allocation guidelines are determined in consultation with the Company’s investment consultant, and through the use of modeling the risk/return trade-offs among asset classes utilizing assumptions about expected annual return, expected volatility/standard deviation of returns, and expected correlations with other asset classes.  In Fiscal 2015, the Company plans to begin investing in liability-driven investment funds, which will change the asset allocations.
For the Company’s non-U.S. plans, the general investment objectives are to maintain a suitably diversified portfolio of secure assets of appropriate liquidity which will generate income and capital growth to meet, together with any new contributions from members and the Company, the cost of current and future benefits.  Investment policy and performance is measured and monitored on an ongoing basis by the Company’s investment committee through its use of an investment consultant and through quarterly investment portfolio reviews.
Estimated Contributions and Future Payments The Company’s general funding policy for its pension plans is to make at least the minimum contributions as required by applicable regulations.  Additionally, the Company may elect to make additional contributions up to the maximum tax deductible contribution.  The Company made contributions of $0.6 million to its U.S. pension plans in Fiscal 2014.  The minimum funding requirement for the Company’s U.S. plans is $12.2 million in Fiscal 2015.  Per the Pension Protection Act of 2006, this obligation could be met with existing credit balances that resulted from payments above the minimum obligation in prior years.  As such, the Company does not anticipate making a contribution in Fiscal 2015 to its U.S. pension plans.  The Company made contributions of $3.7 million to its non-U.S. pension plans in Fiscal 2014 and estimates that it will contribute approximately $3.9 million in Fiscal 2015 based upon the local government prescribed funding requirements.  Future estimates of the Company’s pension plan contributions may change significantly depending on the actual rate of return on plan assets, discount rates, and regulatory requirements.
Estimated future benefit payments for the Company’s U.S. and non-U.S. plans are as follows (thousands of dollars):
Fiscal Year
2015	$	23,032
2016	$	22,728
2017	$	27,717
2018	$	25,059
2019	$	27,754
2020-2024	$	149,865
Postemployment and Postretirement Benefit Plans The Company provides certain postemployment and postretirement health care benefits for certain U.S. employees for a limited time after termination of employment.  The Company has recorded a liability for its postretirement benefit plan in the amount of $1.3 million for both the years ended July 31, 2014 and 2013.  The annual cost resulting from these benefits is not material.  For measurement purposes, a  7.0 percent annual rate of increase in the per capita cost of covered health care benefits was assumed for Fiscal 2014.  The Company has assumed that the long-term rate of increase will decrease gradually to an ultimate annual rate of 4.5 percent.  A one-percentage point increase in the health care cost trend rate would increase the Fiscal 2014 and 2013 liability by $0.1 million.
Retirement Savings and Employee Stock Ownership Plan  The Company provides a contributory employee savings plan to U.S. employees that permits participants to make contributions by salary reduction pursuant to section 401(k) of the Internal Revenue Code.  Employee contributions of up to 25 percent of compensation are matched at a rate equaling 100 percent of the first 3 percent contributed and 50 percent of the next 2 percent contributed.  The Company’s contributions under this plan are based on the level of employee contributions.  Total contribution expense for these plans was $8.1 million, $7.3 million, and $5.5 million for the years ended July 31, 2014, 2013, and 2012, respectively.  This plan also includes shares from an Employee Stock Ownership Plan (ESOP).  As of July 31, 2014, all shares of the ESOP have been allocated to participants.  Total ESOP shares are considered to be shares outstanding for earnings per share calculations.  In July 2013, the Company announced that Employees hired on or after August 1, 2013 will be eligible for a 3 percent annual Company retirement contribution in addition to the Company’s 401(k) match.  Effective August 1, 2016, Employees hired prior to August 1, 2013 will be eligible for the 3 percent annual Company retirement contribution.
Deferred Compensation and Other Benefit Plans The Company provides various deferred compensation and other benefit plans to certain executives.  The deferred compensation plan allows these employees to defer the receipt of all of their bonus and other stock related compensation and up to 75 percent of their salary to future periods.  Other benefit plans are provided to supplement the benefits for a select group of highly compensated individuals which are reduced because of compensation limitations set by the Internal Revenue Code.  The Company has recorded a liability of $9.1 million and $9.5 million the years ended July 31, 2014 and July 31, 2013, respectively, related primarily to its deferred compensation plans.

	NOTE G  Shareholders’ Equity
	Stock Rights On January 27, 2006, the Board of Directors of the Company approved the extension of the benefits afforded by the Company’s existing rights plan by adopting a new shareholder rights plan.  Pursuant to the Rights Agreement, dated as of January 27, 2006 by and between the Company and Wells Fargo Bank, N.A., as Rights Agent, one right was issued on March 3, 2006 for each outstanding share of common stock of the Company upon the expiration of the Company’s existing rights.  Each of the new rights entitles the registered holder to purchase from the Company one one-thousandth of a share of Series A Junior Participating Preferred Stock, without par value, at a price of $143.00 per one one-thousandth of a share.  The rights, however, will not become exercisable unless and until, among other things, any person acquires 15 percent or more of the outstanding common stock of the Company.  If a person acquires 15 percent or more of the outstanding common stock of the Company (subject to certain conditions and exceptions more fully described in the Rights Agreement), each right will entitle the holder (other than the person who acquired 15 percent or more of the outstanding common stock) to purchase common stock of the Company having a market value equal to twice the exercise price of a right.  The rights are redeemable under certain circumstances at $.001 per right and will expire, unless earlier redeemed, on March 2, 2016.
	Stock Compensation Plans The Stock Compensation Plans in the Consolidated Statements of Changes in Shareholders’ Equity consist of the balance of amounts payable to eligible participants for stock compensation that was deferred to a Rabbi Trust pursuant to the provisions of the 2010 Master Stock Incentive Plan, as well as performance awards payable in common stock discussed further in Note I.
	Treasury Stock The Board of Directors authorized the repurchase, at the Company’s discretion, of up to 15.0 million shares of common stock under the Company’s stock repurchase plan dated September 27, 2013.  As of July 31, 2014, the Company had remaining authorization to repurchase 8.5 million shares under this plan.  Following is a summary of treasury stock share activity for Fiscal 2014 and 2013:

Stock Option Plans	'
	NOTE I  Stock Option Plans
	Employee Incentive Plans In November 2010, shareholders approved the 2010 Master Stock Incentive Plan (the Plan).  The Plan extends through September 2020 and allows for the granting of nonqualified stock options, incentive stock options, restricted stock, restricted stock units, stock appreciation rights (SAR), dividend equivalents, and other stock-based awards.  Options under the Plan are granted to key employees at market price at the date of grant.  Options are generally exercisable for up to 10 years from the date of grant.  The Plan also allows for the granting of performance awards to a limited number of key executives.  As administered by the Human Resources Committee of the Company’s Board of Directors to date, these performance awards are payable in common stock and are based on a formula which measures performance of the Company over a three-year period. Performance award expense under these plans totaled $0.7 million in Fiscal 2014, $0.1 million in Fiscal 2013, and $1.9 million in Fiscal 2012.
	Stock options for non-executives are exercisable in equal increments over three years.  Stock options issued after Fiscal 2010 become exercisable for executives in equal increments over three years.  Stock options issued from Fiscal 2004 to Fiscal 2010 became exercisable for most executives immediately upon the date of grant.  For Fiscal 2014, the Company recorded pre-tax compensation expense associated with stock options of $9.9 million and recorded $3.2 million of related tax benefit.  For Fiscal 2013 and 2012, the Company recorded pre-tax compensation expense associated with stock options of $8.3 million and $7.8 million, respectively, and $2.7 million and $2.5 million, respectively, of related tax benefit.
	Stock-based employee compensation cost is recognized using the fair-value based method. The Company determined the fair value of these awards using the Black-Scholes option pricing model, with the following weighted average assumptions:
		2014		2013		2012
	Risk - free interest rate	0.31 - 2.8%		0.02 - 1.7%		0.10 - 1.8%
	Expected volatility	18.2 - 28.0%		22.5 - 29.7%		25.8 - 31.9%
	Expected dividend yield	1.4 - 1.6%		1.0 - 1.4%		1.0%
	Expected life
	Director and officer grants	8 years		8 years		8 years
	Non - officer original grants	7 years		7 years		7 years
	Reload grants	<6 years		<5 years		<8 years
	Black-Scholes is a widely accepted stock option pricing model.  The weighted average fair value for options granted during Fiscal 2014, 2013, and 2012 was  $11.44,  $8.18, and $9.37 per share, respectively, using the Black-Scholes pricing model.
	Reload grants are grants made to officers or directors who exercised a reloadable option during the fiscal year and made payment of the purchase price using shares of previously owned Company stock. The reload grant is for the number of shares equal to the shares used in payment of the purchase price and/or withheld for minimum tax withholding.  Options with a reload provision were no longer issued to officers with more than five years of service and all directors beginning in Fiscal 2006.  The Company continued to issue options with a reload provision to officers with less than five years of service until Fiscal 2011 when this was discontinued.

	Prepaid tax assets		4,392			4,015
	Net tax asset	$	6,853		$	1,751
	Deferred income tax assets on the face of the balance sheet include $4.4 million and $4.0 million of prepaid tax assets related to intercompany transfers of inventory as of July 31, 2014 and 2013, respectively.
	The effective tax rate for Fiscal 2014 was 27.9 percent compared to 29.0 percent in Fiscal 2013.  The decrease in the effective tax rate is primarily due to the favorable settlement of a tax audit, the remeasurement of certain deferred tax assets due to a change in tax rates in certain foreign jurisdictions, and a favorable shift in the mix of earnings between tax jurisdictions.  This was partially offset by tax costs associated with foreign dividend distributions and the expiration of the Research and Experimentation Credit in the U.S. in the current year.
	The Company has not provided for U.S. income taxes on additional undistributed earnings of non-U.S. subsidiaries of approximately $914.0 million.  The Company currently intends to indefinitely reinvest these undistributed earnings as there are significant investment opportunities outside the U.S. or to repatriate the earnings only when it is tax effective to do so.  If any portion were to be distributed, the related U.S. tax liability may be reduced by foreign income taxes paid on those earnings plus any available foreign tax credit carryovers.  Determination of the unrecognized deferred tax liability related to these undistributed earnings is not practicable.  In August 2014, the Company repatriated $52.4 million of cash held by its foreign subsidiaries in the form of a cash dividend.  This dividend represented a portion of the total planned dividends for Fiscal 2015.  At this time, the Company anticipates the net tax impact of the Fiscal 2015 dividends to be tax neutral.
	The Company maintains a reserve for uncertain tax benefits.  The accounting standard defines the threshold for recognizing the benefits of tax return positions in the financial statements as "more-likely-than-not" to be sustained by the taxing authorities based solely on the technical merits of the position.  If the recognition threshold is met, the tax benefit is measured and recognized as the largest amount of tax benefit that in the Company’s judgment is greater than 50 percent likely to be realized.  A reconciliation of the beginning and ending amount of gross unrecognized tax benefits is as follows:
		2014			2013		2012
		(thousands of dollars)
	Gross unrecognized tax benefits at beginning of fiscal year	$	18,419		$	16,514	$	20,005
	Additions for tax positions of the current year		2,959			5,453		3,323
	Additions for tax positions of prior years		1,706			407		261
	Reductions for tax positions of prior years		-7,113			-1,640		-4,462
	Settlements		-240			-277		-
	Reductions due to lapse of applicable statute of limitations		-726			-2,038		-2,613
	Gross unrecognized tax benefits at end of fiscal year	$	15,005		$	18,419	$	16,514
The Company recognizes interest and penalties accrued related to unrecognized tax benefits in income tax expense.  During the fiscal year ended July 31, 2014, the Company recognized interest expense, net of tax benefit, of approximately $0.3  million.  At July 31, 2014 and July 31, 2013, accrued interest and penalties on a gross basis were $1.7 million and $1.1 million, respectively.
The Company files income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions.  With few exceptions, the Company is no longer subject to state and foreign income tax examinations by tax authorities for years before 2008.  The IRS has completed examinations of the company’s U.S. federal income tax returns through 2012.
If the Company were to prevail on all unrecognized tax benefits recorded, substantially all of the unrecognized tax benefits would benefit the effective tax rate.  With an average statute of limitations of about 5 years, up to $1.0 million of the unrecognized tax benefits could potentially expire in the next 12 month period, unless extended by audit.  It is possible that quicker than expected settlement of either current or future audits and disputes would cause additional reversals of previously recorded reserves in the next 12 month period.  Currently, the Company has approximately $0.2 million of unrecognized tax benefits that are in formal dispute with various taxing authorities related to transfer pricing and deductibility of expenses.  Quantification of an estimated range and timing of future audit settlements cannot be made at this time.

Segment Reporting [Abstract]	'
Segment Reporting	'
	NOTE K  Segment Reporting
	Consistent with FASB guidance related to segment reporting, the Company identified two reportable segments: Engine Products and Industrial Products.  Segment selection was based on the internal organizational structure, management of operations, and performance evaluation by management and the Company’s Board of Directors.
	The Engine Products segment sells to original equipment manufacturers (OEM) in the construction, mining, agriculture, aerospace, defense, and truck markets, and to independent distributors, OEM dealer networks, private label accounts, and large equipment fleets. Products include air filtration systems, exhaust and emissions systems, liquid filtration systems including hydraulics, fuel and lube, and replacement filters.
	The Industrial Products segment sells to various industrial dealers, distributors, OEMs of gas-fired turbines, and OEMs and end-users requiring clean air.  Products include dust, fume, and mist collectors, compressed air purification systems, air filtration systems for gas turbines, PTFE membrane-based products, and specialized air and gas filtration systems for applications including computer hard disk drives and semi-conductor manufacturing.
	Corporate and Unallocated includes corporate expenses determined to be non-allocable to the segments such as interest income and interest expense.  Assets included in Corporate and Unallocated principally are cash and cash equivalents, inventory reserves, certain prepaids, certain investments, other assets, and assets allocated to general corporate purposes.
	The Company has an internal measurement system to evaluate performance and allocate resources based on profit or loss from operations before income taxes.  The Company’s manufacturing facilities serve both reporting segments.  Therefore, the Company uses an allocation methodology to assign costs and assets to the segments.  A certain amount of costs and assets relate to general corporate purposes and are not assigned to either segment.  The accounting policy applied to inventory for the reportable segments differs from that described in the summary of significant accounting policies.  The reportable segments account for inventory on a standard cost basis, which is consistent with our internal reporting.
	Segment allocated assets are primarily accounts receivable, inventories, property, plant, and equipment, and goodwill.  Reconciling items included in Corporate and Unallocated are created based on accounting differences between segment reporting and the consolidated, external reporting as well as internal allocation methodologies.
	The Company is an integrated enterprise, characterized by substantial intersegment cooperation, cost allocations, and sharing of assets.  Therefore, the Company does not represent that these segments, if operated independently, would report the operating profit and other financial information shown below.
	Segment detail is summarized as follows:

Summary_Of_Significant_Account1

Summary Of Significant Accounting Policies (Policy)	12 Months Ended
	Jul. 31, 2014
Summary Of Significant Accounting Policies [Abstract]	'
Principles Of Consolidation	'
	Principles of Consolidation The Consolidated Financial Statements include the accounts of Donaldson Company, Inc. and all majority-owned subsidiaries.  All intercompany accounts and transactions have been eliminated.  The Company’s three joint ventures that are not majority-owned are accounted for under the equity method.
Use Of Estimates	'
	Use of Estimates The preparation of Financial Statements in conformity with generally accepted accounting principles in the United States of America (U.S.) (U.S. GAAP) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes.  Actual results could differ from those estimates.
Foreign Currency Translation	'
	Foreign Currency Translation For substantially all foreign operations, local currencies are considered the functional currency.  Assets and liabilities of non-U.S. dollar functional currency entities are translated to U.S. dollars at year-end exchange rates and the resulting gains and losses arising from the translation of net assets located outside the U.S. are recorded as a cumulative translation adjustment, a component of Accumulated other comprehensive income (loss) (AOCI) in the Consolidated Balance Sheets.  Elements of the Consolidated Statements of Earnings are translated at average exchange rates in effect during the year.  Realized and unrealized foreign currency transaction gains and losses are included in Other income, net in the Consolidated Statements of Earnings.  Foreign currency translation gains of $1.7 million, $0.2 million, and $1.8 million are included in Other income, net in the Consolidated Statements of Earnings in Fiscal 2014, 2013, and 2012, respectively.
Cash Equivalents	'
	Cash Equivalents The Company considers all highly liquid temporary investments with an original maturity of three months or less to be cash equivalents.  Cash equivalents are carried at cost that approximates market value.
Short-Term Investments	'
	Short-Term Investments As of July 31, 2014 and 2013, the Company’s short-term investments consisted exclusively of time deposits with durations longer than 3 months, but less than 1 year.  These investments are carried at cost, which approximates their estimated fair value.  Classification of the Company’s investments as current or non-current is dependent upon management’s intended holding period, the investment’s maturity date, and liquidity considerations based on market conditions.  If management intends to hold the investments for longer than one year as of the balance sheet date, they are classified as non-current.
Accounts Receivable And Allowance For Doubtful Accounts	'
	Accounts Receivable and Allowance for Doubtful Accounts Trade accounts receivable are recorded at the invoiced amount and do not bear interest.  The allowance for doubtful accounts is the Company’s best estimate of the amount of credit losses in its existing accounts receivable.  The Company determines the allowance based on historical write-off experience in the industry, regional economic data, and evaluation of specific Customer accounts for risk of loss.  The Company reviews its allowance for doubtful accounts monthly.  Past due balances over 90 days and over a specified amount are reviewed individually for collectability.  All other balances are reviewed on a pooled basis by type of receivable.  Account balances are charged off against the allowance when the Company feels it is probable the receivable will not be recovered.  The Company does not have any off-balance-sheet credit exposure related to its Customers.
Inventories	'
	Inventories Inventories are stated at the lower of cost or market.  U.S. inventories are valued using the last-in, first-out (LIFO) method, while the non-U.S. inventories are valued using the first-in, first-out (FIFO) method.  Inventories valued at LIFO were approximately 33 percent of total inventories at July 31, 2014 and 2013.  For inventories valued under the LIFO method, the FIFO cost exceeded the LIFO carrying values by $37.9 million and $37.8 million at July 31, 2014 and 2013, respectively.  Results of operations for all periods presented were not materially affected by the liquidation of LIFO inventory.  The components of inventory are as follows (thousands of dollars):
		At July 31,

Property, Plant And Equipment	'
	Property, Plant, and Equipment Property, plant, and equipment are stated at cost.  Additions, improvements, or major renewals are capitalized, while expenditures that do not enhance or extend the asset’s useful life are charged to expense as incurred.  Depreciation is computed under the straight-line method.  Depreciation expense was $62.0 million in Fiscal 2014, $58.8 million in Fiscal 2013, and $55.3 million in Fiscal 2012.  The estimated useful lives of property, plant, and equipment are 10 to 40 years for buildings, including building improvements, and 3 to 10 years for machinery and equipment.  The components of property, plant, and equipment are as follows (thousands of dollars):
		At July 31,
		2014		2013
	Land	$	20,558	$	21,116
	Buildings		273,599		270,022
	Machinery and equipment		753,637		687,797
	Construction in progress		51,394		46,078
	Less accumulated depreciation		-647,523		-605,733
	Total property, plant, and equipment, net	$	451,665	$	419,280
Internal-Use Software	'
	Internal-Use Software The Company capitalizes direct costs of materials and services used in the development and purchase of internal-use software.  Amounts capitalized are amortized on a straight-line basis over a period of five to seven years and are reported as a component of machinery and equipment within property, plant, and equipment.
Goodwill And Other Intangible Assets	'
	Goodwill and Other Intangible Assets Goodwill represents the excess of the purchase price over the fair value of net assets acquired in business combinations under the purchase method of accounting.  Other intangible assets, consisting primarily of patents, trademarks, and Customer relationships and lists, are recorded at cost and are amortized on a straight-line basis over their estimated useful lives of 3 to 20 years.  Goodwill is assessed for impairment annually or if an event occurs or circumstances change that would indicate the carrying amount may be impaired.  The impairment assessment for goodwill is done at a reporting unit level.  Reporting units are one level below the operating segment level, but can be combined when reporting units within the same operating segment have similar economic characteristics.  An impairment loss generally would be recognized when the carrying amount of the reporting unit’s net assets exceeds the estimated fair value of the reporting unit.
Recoverability Of Long-Lived Assets	'
	Recoverability of Long-Lived Assets The Company reviews its long-lived assets, including identifiable intangibles, for impairment when events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.  If impairment indicators are present and the estimated future undiscounted cash flows are less than the carrying value of the assets, the carrying value is reduced.  There were no significant impairment charges recorded in Fiscal 2014, Fiscal 2013, or Fiscal 2012.
Income Taxes	'
	Income Taxes The provision for income taxes is computed based on the pre-tax income reported for financial statement purposes.  Deferred tax assets and liabilities are recognized for the expected future tax consequences attributed to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis.  Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to reverse.  Valuation allowances are recorded to reduce deferred tax assets when it is more-likely-than-not that a tax benefit will not be realized.
Comprehensive Income (Loss)	'
	Comprehensive Income (Loss) Comprehensive income (loss) consists of net income, foreign currency translation adjustments, net changes in the funded status of pension retirement obligations, and net gains or losses on cash flow hedging derivatives, and is presented in the Consolidated Statements of Changes in Shareholders’ Equity.  The components of the ending balances of AOCI are as follows (thousands of dollars):
		At July 31,
		2014		2013		2012
	Foreign currency translation adjustment	$	48,289	$	50,411	$	32,976
	Net loss on cash flow hedging derivatives, net of deferred taxes		-101		-172		-292
	Pension and postretirement liability adjustment, net of deferred taxes		-93,998		-87,712		-134,572
	Total accumulated other comprehensive loss	$	-45,810	$	-37,473	$	-101,888
	Cumulative foreign currency translation is not adjusted for income taxes.  See Note H for additional disclosures related to AOCI.
Earnings Per Share	'
	Earnings Per Share The Company’s basic net earnings per share are computed by dividing net earnings by the weighted average number of outstanding common shares.  The Company’s diluted net earnings per share is computed by dividing net earnings by the weighted average number of outstanding common shares and common equivalent shares relating to stock options and stock incentive plans.  Certain outstanding options were excluded from the diluted net earnings per share calculations because their exercise prices were greater than the average market price of the Company’s common stock during those periods.  There were 884,138 options, 22,619 options, and 1,063,135 options excluded from the diluted net earnings per share calculation for the fiscal year ended July 31, 2014, 2013, and 2012, respectively.
	The following table presents information necessary to calculate basic and diluted earnings per share:
		2014		2013		2012
		(thousands, except per share amounts)
	Weighted average shares - basic		145,594		148,274		150,286
	Diluted share equivalents		2,047		2,181		2,655
	Weighted average shares - diluted		147,641		150,455		152,941
	Net earnings for basic and diluted earnings

	Net earnings per share - basic	$	1.79	$	1.67	$	1.76
	Net earnings per share - diluted	$	1.76	$	1.64	$	1.73
	On January 27, 2012, the Company announced that its Board of Directors declared a two-for-one stock split effected in the form of a 100 percent stock dividend. The stock split was distributed March 23, 2012, to stockholders of record as of March 2, 2012.  Earnings and dividends per share and weighted average shares outstanding are presented in this Form 10-K after the effect of the 100 percent stock dividend.  The two-for-one stock split is reflected in the share amounts in all periods presented in the table above and elsewhere in this annual Form 10-K.
Treasury Stock	'
	Treasury Stock Repurchased common stock is stated at cost (determined on an average cost basis) and is presented as a reduction of shareholders’ equity.
Research And Development	'
	Research and Development Research and development costs are charged against earnings in the year incurred.  Research and development expenses include basic scientific research and the application of scientific advances to the development of new and improved products and their uses.
Stock-Based Compensation	'
	Stock-Based Compensation The Company offers stock-based employee compensation plans, which are more fully described in Note I.  Stock-based employee compensation cost is recognized using the fair-value based method.
Revenue Recognition	'
	Revenue Recognition Revenue is recognized when all the following criteria are satisfied: (a) persuasive evidence of a sales arrangement exists; (b) price is fixed and determinable; (c) collectability is reasonably assured; and (d) delivery has occurred.  At that time, product ownership and the risk of loss have transferred to the Customer and the Company has no remaining obligations.  The Company records estimated discounts and rebates as a reduction of sales in the same period revenue is recognized.  Shipping and handling costs for Fiscal 2014, 2013, and 2012 totaled $64.2 million, $66.2 million, and $67.0 million, respectively, and are classified as a component of selling, general, and administrative expenses.
Product Warranties	'
	Product Warranties The Company provides for estimated warranty costs at the time of sale and accrues for specific items at the time their existence is known and the amounts are determinable.  The Company estimates warranty costs using standard quantitative measures based on historical warranty claim experience and evaluation of specific Customer warranty issues.  For a warranty reserve reconciliation see Note M.
Derivative Instruments And Hedging Activities	'
	Derivative Instruments and Hedging Activities The Company recognizes all derivatives on the balance sheet at fair value.  Derivatives that are not designated as hedges are adjusted to fair value through income.  If the derivative is designated as a hedge, depending on the nature of the hedge, changes in the fair value of derivatives are either offset against the change in fair value of the hedged assets, liabilities, or firm commitments through earnings or recognized in shareholders’ equity through other comprehensive income until the hedged item is recognized.  Gains or losses related to the ineffective portion of any hedge are recognized through earnings in the current period.
New Accounting Standards Recently Adopted	'
	New Accounting Standards Recently Adopted In February 2013, the FASB updated the disclosure requirements for AOCI.  The updated guidance requires companies to disclose amounts reclassified out of AOCI by component.  The updated guidance only impacts disclosure requirements and does not affect how net income or other comprehensive income are calculated.  The updated guidance was adopted by the Company beginning in the first quarter of Fiscal 2014.  For additional information, refer to Note H.
