NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

(1) Condensed Consolidated Financial Statements

The condensed consolidated financial statements are presented in accordance with the rules and regulations of the Securities and Exchange Commission (SEC) and do not include all of the disclosures normally required by U.S. generally accepted accounting principles as contained in Lindsay Corporation’s (the “Company”) Annual Report on Form 10-K. Accordingly, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s latest Annual Report on Form 10-K for the fiscal year ended August 31, 2011.

In the opinion of management, the condensed consolidated financial statements of the Company reflect all adjustments (consisting of only normal recurring accruals) necessary to present fairly the financial position and the results of operations and cash flows for the periods presented. The results for interim periods are not necessarily indicative of trends or results expected by the Company for a full year.

The condensed consolidated financial statements were prepared using accounting principles generally accepted in the United States. These principles require us to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities and the reported amounts of revenues and expenses. Actual results could differ from these estimates. Certain reclassifications have been made to prior financial statements and notes to conform to the current year presentation. These reclassifications were not material to the Company’s condensed consolidated financial statements.

(2) Net Earnings per Share

Basic net earnings per share is computed using the weighted-average number of common shares outstanding during the period. Diluted net earnings per share is computed using the weighted-average number of common shares outstanding plus dilutive potential common shares outstanding during the period.

Employee stock options, nonvested shares and similar equity instruments granted by the Company are treated as potential common share equivalents outstanding in computing diluted net earnings per share. The Company’s diluted common shares outstanding reported in each period includes the dilutive effect of restricted stock units, in-the-money options, and performance stock units for which threshold performance conditions have been satisfied and is calculated based on the average share price for each fiscal period using the treasury stock method.

The following table shows the securities excluded from the computation of earnings per share since their inclusion would have been anti-dilutive:

	Three months ended May 31,				Nine months ended May 31,
	2012		2011		2012		2011
Restricted stock units		—		—		4,322		2,750
Stock options		34,971		—		27,805		—

Performance stock units are excluded from the calculation of dilutive potential common shares until the threshold performance conditions have been satisfied. At May 31, 2012, the threshold performance conditions for the November 12, 2009 grants had been satisfied resulting in the inclusion of 37,746 performance stock units in the calculation of diluted net earnings per share. At May 31, 2012 and 2011, there were 43,388 and 98,625, respectively, of performance stock units excluded from the calculation of diluted net earnings per share because the threshold performance conditions had not been satisfied.

(3) Comprehensive Income

The accumulated other comprehensive income, net, shown in the Company’s condensed consolidated balance sheets includes the unrealized gain (loss) on cash flow hedges, net actuarial losses from the defined benefit pension plan, and the accumulated foreign currency translation adjustment, net of hedging activities. The following table shows the difference between the Company’s reported net earnings and its comprehensive income:

	Three months ended May 31,					Nine months ended May 31,
$ in thousands	2012			2011		2012			2011

⁽¹⁾  Net of tax expense of $530 and $885 for the three months and nine months ended May 31, 2012, respectively. Net of tax expense of $215 and $394 for the three months and nine months ended May 31, 2011, respectively.

(4) Income Taxes

It is the Company’s policy to report income tax expense for interim periods using an estimated annual effective income tax rate. However, the tax effects of significant or unusual items are not considered in the estimated annual effective tax rate. The tax effects of such discrete events are recognized in the interim period in which the events occur. For the three and nine months ended May 31, 2012 and 2011, the Company recorded no material discrete items.

The Company recorded income tax expense of $9.8 million and $17.9 million for the three and nine months ended May 31, 2012, respectively. The Company recorded income tax expense of $7.9 million and $15.8 million for the three and nine months ended May 31, 2011, respectively. The calculated effective tax rate (defined as income tax provision divided by earnings before income taxes) was 34.2 percent and 34.0 percent for the three months ended May 31, 2012 and 2011, respectively. The calculated effective tax rate was 34.2 percent and 33.9 percent for the year-to-date periods ended May 31, 2012 and 2011, respectively.

(5) Inventories

Inventories are stated at the lower of cost or market. Cost is determined by the last-in, first-out (LIFO) method for the Company’s Lindsay, Nebraska inventory and its two warehouses in Idaho and Texas. Cost is determined by the first-in, first-out (FIFO) method for inventory at the Company’s Omaha, Nebraska warehouse, and at operating locations in California, Wisconsin, China and Australia. Cost is determined by the weighted average cost method for inventory at the Company’s other operating locations in Washington State, France, Brazil, Italy, and South Africa. The Company reserves for obsolete, slow moving, and excess inventory by estimating the net realizable value based on potential future use of such inventory.

(7) Credit Arrangements

At May 31, 2012 and 2011 and August 31, 2011, the Company believes it was in compliance with all loan covenants. Changes to credit arrangements since August 31, 2011 consist of the following:

Euro Line of Credit

The Company’s wholly-owned European subsidiary, Lindsay Europe, has an unsecured revolving line of credit with Societe Generale, a European commercial bank, under which it could borrow for working capital purposes up to 2.3 million Euros (the “Euro Line of Credit”). On January 23, 2012, the Company extended the Euro Line of Credit with Societe Generale through January 31, 2013. There were no borrowings outstanding on this credit agreement at May 31, 2012 or August 31, 2011. There was $1.3 million outstanding on this credit agreement at May 31, 2011. Under the terms of the Euro Line of Credit, borrowings, if any, bear interest at a floating rate in effect from time to time designated by the commercial bank as the Euro Interbank Offered Rate plus 110 basis points, (1.78 percent at May 31, 2012). Unpaid principal and interest is due by January 31, 2013.

Due within:
1 year	$	4,286
2 years		1,071
	$	5,357

(8) Financial Derivatives

The Company uses certain financial derivatives to mitigate its exposure to volatility in interest rates and foreign currency exchange rates. The Company uses these derivative instruments to hedge exposures in the ordinary course of business and does not invest in derivative instruments for speculative purposes. Each derivative is designated as a cash flow hedge, a hedge of a net investment, or remains undesignated. The Company records the fair value of these derivative instruments on the balance sheet. For the instruments that are designated as a cash flow hedge and meet certain documentary and analytical requirements to qualify for hedge accounting treatment, changes in the fair value for the effective portion are reported in other comprehensive income (“OCI”), net of related income tax effects, and are reclassified to the income statement when the effects of the item being hedged are recognized in the income statement. Changes in fair value of derivative instruments that qualify as hedges of a net investment in foreign operations are recorded as a component of accumulated currency translation adjustment in accumulated other comprehensive income (“AOCI”), net of related income tax effects. Changes in the fair value of undesignated hedges are recognized currently in the income statement as other income (expense). All changes in derivative fair values due to ineffectiveness are recognized in earnings.

The Company manages market and credit risks associated with its derivative instruments by establishing and monitoring limits as to the types and degree of risk that may be undertaken, and by entering into transactions with high-quality counterparties. As of May 31, 2012, the Company’s derivative counterparty had investment grade credit ratings.

Financial derivatives consist of the following:

	Fair Values of Derivative Instruments
	Asset (Liability)
		May 31,			May 31,			August 31,
$ in thousands	Balance Sheet Location	2012			2011			2011

Derivatives not designated as hedging instruments:

Total derivatives not designated as hedging instruments		$	116		$	—		$	—

In addition, accumulated other comprehensive income included realized and unrealized gains, net of related income tax effects, of $2.7 million, $0.4 million and $0.5 million at May 31, 2012 and 2011 and August 31, 2011, respectively, related to derivative contracts designated as hedging instruments.

Cash Flow Hedging Relationships

In order to reduce interest rate risk on the BSI Term Note, the Company entered into an interest rate swap agreement with Wells Fargo Bank, N.A. that is designed to convert the variable interest rate on the entire amount of the borrowing to a fixed rate of 6.05 percent per annum. Under the terms of the interest rate swap, the Company receives variable interest rate payments and makes fixed interest rate payments on an amount equal to the outstanding balance of the BSI Term Note. Changes in the fair value of the interest rate swap designated as a hedging instrument that effectively offset the variability of cash flows associated with variable-rate, long-term debt obligations are reported in AOCI, net of related income tax effects.

In order to reduce exposures related to changes in foreign currency exchange rates, the Company, at times, may enter into forward exchange or option contracts for transactions denominated in a currency other than the functional currency for certain of its operations. This activity primarily relates to economically hedging against foreign currency risk in purchasing inventory, sales of finished goods, and future settlement of foreign denominated assets and liabilities. Changes in the fair value of the forward exchange contracts or option contracts designated as hedging instruments that effectively offset the hedged risks are reported in AOCI, net of related income tax effects. The Company had $2.3 million, $1.1 million, and $0.7 million of U.S. dollar equivalent cash flow forward exchange contracts and option contracts outstanding as of May 31, 2012 and 2011, and August 31, 2011, respectively. In addition, the amount of gain or loss recognized in OCI, the amount of gain or loss reclassified from AOCI into income and the amount of gain or loss recognized in income related to the outstanding cash flow hedging relationships were immaterial.

Net Investment Hedging Relationships

In order to reduce translation exposure resulting from translating the financial statements of its international subsidiaries into U.S. dollars, the Company, at times, utilizes Euro foreign currency forward contracts to hedge a portion of its Euro net investment exposure in its foreign operations. These foreign currency forward contracts qualify as a hedge of net investments in foreign operations. Changes in fair value of the net investment hedge contracts are reported in OCI as part of the currency translation adjustment, net of tax.

For the three and nine months ended May 31, 2012, the Company settled Euro foreign currency forward contracts resulting in after-tax net loss (gain) of $0.2 million and ($0.8) million, respectively, which were included in OCI as part of a currency translation adjustment. For the three and nine months ended May 31, 2011, the Company settled Euro foreign currency forward contracts resulting in after-tax net loss of $0.3 million and $0.7 million, respectively, which were included in OCI as part of a currency translation adjustment.

There were no amounts recorded in the condensed consolidated statement of operations related to ineffectiveness of Euro foreign currency forward contracts for the three and nine months ended May 31, 2012 and 2011. Accumulated currency translation adjustments in AOCI at May 31, 2012 and 2011 and August 31, 2011 reflected realized and unrealized after-tax gains of $2.7 million, $0.8 million and $0.9 million, respectively.

At May 31, 2012 and 2011 and August 31, 2011, the Company had outstanding Euro foreign currency forward contracts to sell 22.5 million Euro, 10.0 million Euro and 10.0 million Euro, respectively, at fixed prices to settle during the next fiscal quarter. The Company’s foreign currency forward contracts qualify as hedges of a net investment in foreign operations.

The carrying amount of long-term debt (including current portion) was $5.4 million, $9.6 million and $8.6 million as of May 31, 2012 and 2011 and August 31, 2011, respectively. The fair value of this debt was estimated at $5.3 million, $9.5 million, and $8.5 million as of May 31, 2012 and 2011 and August 31, 2011, respectively. Fair value of long-term debt (including current portion) is estimated by discounting the future estimated cash flows of each instrument at current market interest rates for similar debt instruments of comparable maturities and credit quality.

The Company also measures the fair value of certain assets on a non-recurring basis, generally quarterly, annually, or when events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. These assets include fixed assets, goodwill, and other intangible assets. There were no required fair value adjustments for assets and liabilities measured at fair value on a non-recurring basis for the three and nine months ended May 31, 2012 and 2011.

(10) Commitments and Contingencies

In 1992, the Company entered into a consent decree with the Environmental Protection Agency of the United States Government (the “EPA”) in which the Company committed to remediate environmental contamination of the groundwater that was discovered in 1982 through 1990 at and adjacent to its Lindsay, Nebraska facility (the “site”). The site was added to the EPA’s list of priority superfund sites in 1989. Between 1993 and 1995, remediation plans for the site were approved by the EPA and fully implemented by the Company. Since 1998, the primary remaining contamination at the site has been the presence of volatile organic chemicals in the groundwater. The remediation process consists of drilling wells into the aquifer and pumping water to the surface to allow these contaminants to be removed by aeration. The Company accrues the anticipated cost of remediation when the obligation is probable and can be reasonably estimated.

In 2008, the Company and the EPA conducted their periodic five-year review of the status of the remediation of the contamination of the site. In response to the review, the Company and its environmental consultants have developed a remedial action work plan. In the first quarter of fiscal 2012, the Company undertook an investigation to assess further potential site remediation and containment actions. In connection with the receipt of preliminary results of this investigation and other evaluations, the Company estimated that it would incur $7.2 million in remediation and operating costs and accrued that undiscounted amount as an operating expense in the first quarter of fiscal 2012.

Although the Company has accrued all reasonably estimable costs associated with remediation of the site, it is expected that additional testing and environmental monitoring and remediation will be required in the future as part of the Company’s ongoing discussions with the EPA regarding the development and implementation of the remedial action plans, which could result in changes to its estimates. In addition, the current investigation has not yet been completed and does not include all affected areas on the site. Estimates continue to be refined and evaluated on a number of remediation alternatives and the EPA has not provided approval of possible action plans. While additional estimated expenses could significantly exceed the amount accrued as of May 31, 2012 and could be material to the operating results of any fiscal quarter or fiscal year, the Company does not expect that such additional expenses would have a material adverse effect on its liquidity or financial condition.

The following table summarizes the undiscounted environmental remediation liability classifications included in the balance sheet as of May 31, 2012 and 2011 and August 31, 2011:

(13) Industry Segment Information

The Company manages its business activities in two reportable segments:

Irrigation: This reporting segment includes the manufacture and marketing of center pivot, lateral move, and hose reel irrigation systems as well as various water pumping stations and controls. The irrigation reporting segment consists of twelve operating segments that have similar economic characteristics and meet the aggregation criteria, including similar products, production processes, type or class of customer and methods for distribution.

Infrastructure: This reporting segment includes the manufacture and marketing of moveable barriers, specialty barriers and crash cushions; providing outsource manufacturing services and the manufacturing and selling of large diameter steel tubing and railroad signals and structures. The infrastructure reporting segment consists of three operating segments that have similar economic characteristics and meet the aggregation criteria.

The Company evaluates the performance of its reportable segments based on segment sales, gross profit, and operating income, with operating income for segment purposes excluding unallocated corporate general and administrative expenses, interest income, interest expense, other income and expenses, and income taxes. Operating income for segment purposes does include general and administrative expenses, selling expenses, engineering and research expenses, environmental remediation expenses and other overhead charges directly attributable to the segment. There are no inter-reporting segment sales.

(14) Share-Based Compensation

The Company measures and recognizes compensation expense for all share-based payment awards made to employees and directors based on estimated fair values. The value of the portion of the award that is ultimately expected to vest is recognized as expense in the Company’s condensed consolidated statement of operations over the periods during which the employee or director is required to perform a service in exchange for the award. The Company’s current share-based compensation plan, approved by the stockholders of the Company, provides for awards of stock options, restricted shares, restricted stock units, stock appreciation rights, performance shares and performance stock units to employees and non-employee directors of the Company. In connection with the restricted stock units, performance stock units and stock options, the Company is accruing compensation expense based on the estimated number of shares expected to be issued utilizing the most current information available to the Company at the date of the financial statements. Share-based compensation expense was $0.8 million and $0.8 million for the three months ended May 31, 2012 and 2011, respectively.

ITEM 2 - Management’s Discussion and Analysis of Financial Condition and Results of Operations Concerning Forward-Looking Statements

This quarterly report on Form 10-Q contains not only historical information, but also forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Statements that are not historical are forward-looking and reflect expectations for future Company conditions or performance. In addition, forward-looking statements may be made orally or in press releases, conferences, reports, on the Company’s worldwide web site, or otherwise, in the future by or on behalf of the Company. When used by or on behalf of the Company, the words “expect,” “anticipate,” “estimate,” “believe,” “intend,” “will,” and similar expressions generally identify forward-looking statements. The entire section entitled “Market Conditions and Fiscal 2012 Outlook” should be considered forward-looking statements. For these statements, the Company claims the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995.

Forward-looking statements involve a number of risks and uncertainties, including but not limited to those discussed in the “Risk Factors” section in the Company’s Annual Report on Form 10-K for the year ended August 31, 2011. Readers should not place undue reliance on any forward-looking statement and should recognize that the statements are predictions of future results or conditions, which may not occur as anticipated. Actual results or conditions could differ materially from those anticipated in the forward-looking statements and from historical results, due to the risks and uncertainties described herein, as well as others not now anticipated. The risks and uncertainties described herein are not exclusive and further information concerning the Company and its businesses, including factors that potentially could materially affect the Company’s financial results, may emerge from time to time. Except as required by law, the Company assumes no obligation to update forward-looking statements to reflect actual results or changes in factors or assumptions affecting such forward-looking statements.

Accounting Policies

In preparing the Company’s condensed consolidated financial statements in conformity with U.S. generally accepted accounting principles, management must make a variety of decisions which impact the reported amounts and the related disclosures. These decisions include the selection of the appropriate accounting principles to be applied and the assumptions on which to base accounting estimates. In making these decisions, management applies its judgment based on its understanding and analysis of the relevant circumstances and the Company’s historical experience.

The Company’s accounting policies that are most important to the presentation of its results of operations and financial condition, and which require the greatest use of judgments and estimates by management, are designated as its critical accounting policies. See further discussion of the Company’s critical accounting policies under Item 7 – “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in the Company’s Annual Report on Form 10-K for the Company’s year ended August 31, 2011. Management periodically re-evaluates and adjusts its critical accounting policies as circumstances change. The Company’s critical accounting policies have not changed since the filing of the Annual Report on Form 10-K except as discussed below for environmental remediation liabilities.

Environmental Remediation Liabilities

The Company accrues for environmental remediation liabilities when it is probable that obligations have been incurred and the associated amounts can be reasonably estimated. Management estimates the cost of environmental remediation liabilities by considering all available information, including engineering estimates and legal advice. Environmental remediation liability estimates may be affected by changing assessments from governmental or other third parties for claims of the Company’s environmental remediation liability and the acceptability of the Company’s remediation plan to federal and state environmental regulators. Inherent uncertainties exist in such estimated costs primarily due to unknown environmental conditions, changing governmental regulations and legal standards regarding liability, and emerging remediation technologies. The Company reviews the environmental remediation liabilities for discounting if both the timing and amounts of future cash flows are fixed or reliably determinable. The recorded liabilities are adjusted periodically as remediation efforts progress, or as additional technical or legal information becomes available.

Overview

Operating revenues for the three months ended May 31, 2012 increased by $18.7 million or 12.2 percent to $172.1 million compared with $153.4 million for the three months ended May 31, 2011. The increase is attributable to a $22.7 million increase in irrigation revenues offset in part by a $4.1 million decrease in infrastructure revenues. Net earnings were $18.8 million or $1.47 per diluted share for the three months ended May 31, 2012 compared with $15.3 million or $1.20 per diluted share for the same prior year period.

Farm incomes and commodity prices have driven positive farmer sentiment, leading to increased domestic irrigation demand. The increase in sales, along with cost reductions and efficiency improvements across the Company’s business segments have resulted in higher operating margins in the third quarter. Government funded infrastructure spending remained challenging due to global governmental budget constraints.

Operating revenues for the nine months ended May 31, 2012 increased by $60.6 million or 16.7 percent to $423.4 million compared with $362.8 million for the nine months ended May 31, 2011. The increase is attributable to an $88.8 million increase in irrigation revenues offset in part by a $28.2 million decrease in infrastructure revenues. Net earnings were $34.5 million or $2.70 per diluted share for the nine months ended May 31, 2012 compared with $30.9 million or $2.44 per diluted share for the same prior year period.

(1) Includes $3.9 million and $3.5 million of unallocated general and administrative expenses for the three months ended May 31, 2012 and 2011, respectively.

(2) Excludes unallocated general & administrative expenses. There were no environmental remediation expenses allocated to the irrigation segment and the infrastructure segment for the three months ended May 31, 2012. Environmental remediation expenses of $0.3 and $0.1 million were allocated to the irrigation segment and the infrastructure segment, respectively, for the three months ended May 31, 2011.

Revenues

Operating revenues for the three months ended May 31, 2012 increased by $18.7 million or 12.2 percent to $172.1 million compared with $153.4 million for the three months ended May 31, 2011. The increase is attributable to a $22.7 million increase in irrigation revenues offset in part by a $4.1 million decrease in infrastructure revenues.

U.S. irrigation revenues for the three months ended May 31, 2012 of $105.6 million increased 37.6 percent compared to the three months ended May 31, 2011. The increase in U.S. irrigation revenues is primarily due to an increase in the number of irrigation systems, parts and related services sold compared to the prior year’s third fiscal quarter. Farm incomes and commodity prices have driven positive farmer sentiment, leading to increased domestic irrigation demand. Order volumes continued to be strong throughout the primary selling season and revenues grew in nearly all U.S. regions, with the lowest growth in the drought stricken Texas market.

International irrigation revenues for the three months ended May 31, 2012 of $44.0 million decreased 12.2 percent compared to the three months ended May 31, 2011. Operating revenues decreased primarily due to less international project based revenue. Revenues in China reflected the largest regional variance due to delays in a provincial government tender. The Company anticipates China revenues to recover in the fourth quarter of fiscal 2012.

- 17

Infrastructure segment revenues were $22.5 million for the three months ended May 31, 2012 decreasing 15.3 percent from $26.5 million for the three months ended May 31, 2011 due primarily to lower road safety and rail product sales. Infrastructure sales continue to be constrained by uncertainty of longer term plans for highway projects and government funding.

Gross Margin

Gross profit was $49.0 million for the three months ended May 31, 2012, an increase of $7.5 million compared to $41.5 million of gross profit for three months ended May 31, 2011. Gross margin was 28.5 percent for the three months ended May 31, 2012 compared to 27.0 percent for the three months ended May 31, 2011 reflecting improvements in gross margins in both the irrigation and infrastructure segments. Irrigation gross margins increased due to favorable sales mix. Infrastructure margins improved due to improved product pricing in road safety and diversified products along with efforts to lower manufacturing costs.

Operating Expenses

The Company’s operating expenses of $20.2 million for the three months ended May 31, 2012 were $1.9 million higher than such expenses for the three months ended May 31, 2011. The increase in operating expenses was driven primarily by personnel related expenses and the inclusion of an acquired business. Operating expenses were 11.8 percent of sales for the three months ended May 31, 2012 compared to 12.0 percent of sales for the three months ended May 31, 2011. Operating margin was 16.7 percent for the three months ended May 31, 2012 as compared to 15.1 percent for the three months ended May 31, 2011.

Income Taxes

The Company recorded income tax expense of $9.8 million and $7.9 million for the three months ended May 31, 2012 and 2011, respectively. The calculated effective tax rate (defined as income tax provision divided by earnings before income taxes) was 34.2 percent and 34.0 percent for the three months ended May 31, 2012 and 2011, respectively. For the three months ended May 31, 2012 and 2011, the Company recorded no material discrete items.

Net Earnings

Net earnings were $18.8 million or $1.47 per diluted share for the three months ended May 31, 2012 compared with $15.3 million or $1.20 per diluted share for the same prior year period.

Farm incomes and commodity prices have driven positive farmer sentiment, leading to increased domestic irrigation demand.

International irrigation revenues for the nine months ended May 31, 2012 increased $19.5 million or 19.7 percent to $118.2 million compared with $98.8 million for the nine months ended May 31, 2011. Operating revenues increased in nearly all international markets, most significantly in the Middle East, Canada, Latin America, Africa and Europe. The international sales growth was due to strong agricultural economies around the world as farm commodity prices continue to be favorable in most markets.

Infrastructure segment revenues were $56.1 million for the nine months ended May 31, 2012 decreasing 33.4 percent from $84.2 million for the nine months ended May 31, 2011 due to lower revenues from sales of QMB^® systems. Revenues from QMB^® systems declined compared to the prior year due to the completion of sizeable projects in the prior fiscal year and delays in anticipated projects this fiscal year.

Gross Margin

Gross profit was $115.8 million for the nine months ended May 31, 2012, an increase of $16.1 million compared to $99.7 million of gross profit for the nine months ended May 31, 2011. Gross margin was 27.3 percent for the nine months ended May 31, 2012 compared to 27.5 percent for the nine months ended May 31, 2011. Total gross margin was lower primarily due to lower revenues of higher-margin QMB^® systems. Infrastructure segment gross margins excluding QMB^® systems and irrigation segment gross margin improved due to cost leveraging and productivity gains on higher sales volumes.

Operating Expenses

The Company’s operating expenses of $63.0 million for the nine months ended May 31, 2012 were $10.0 million higher than the nine months ended May 31, 2011. Of the $10.0 million increase in operating expenses, $6.1 million is attributable to the increase in the Company’s environmental remediation accrual over the same prior year period. The remaining increase in operating expenses was driven primarily by personnel related expenses and the inclusion of an acquired business.

In the first quarter of fiscal 2012, the Company undertook an investigation to assess further potential site remediation and containment actions at its Lindsay, Nebraska manufacturing facility. In connection with the receipt of preliminary results of this investigation and other evaluations, the Company estimated that it would incur $7.2 million in remediation and operating costs and accrued that undiscounted amount as an operating expense in the first quarter of fiscal 2012.

Operating margin was 12.5 percent for the nine months ended May 31, 2012 as compared to 12.9 percent for the nine months ended May 31, 2011. Excluding environmental accruals, operating margin was 14.2 percent for the nine months ended May 31, 2012 as compared to 13.2 percent for the nine months ended May 31, 2011. Operating expenses were 14.9 percent of sales for the nine months ended May 31, 2012 compared to 14.6 percent of sales for the nine months ended May 31, 2011. Excluding environmental accruals, operating expenses were 13.2 percent of sales for the nine months ended May 31, 2012 compared to 14.3 percent of sales for the nine months ended May 31, 2011, an improvement attributable primarily to leverage from increased sales generated from substantially similar fixed expenses.

Income Taxes

The Company recorded income tax expense of $17.9 million and $15.8 million for the nine months ended May 31, 2012 and 2011, respectively. The calculated effective tax rate was 34.2 percent and 33.9 percent for the nine months ended May 31, 2012 and 2011, respectively. For the nine months ended May 31, 2012 and 2011, the Company recorded no material discrete items.

Net Earnings

Net earnings were $34.5 million or $2.70 per diluted share for the nine months ended May 31, 2012 compared with $30.9 million or $2.44 per diluted share for the same prior year period. First quarter fiscal 2012 results included $7.2 million of accrued expense, or $0.37 per diluted share on an after tax basis, related to an increase in the Company’s environmental remediation accrual at its Lindsay, Nebraska facility. Comparatively, fiscal 2011 included environmental remediation expense of $1.2 million, or $0.06 per diluted share on an after tax basis.

Liquidity and Capital Resources

The Company’s cash and cash equivalents totaled $119.8 million at May 31, 2012 compared with $100.6 million at May 31, 2011 and $108.2 million at August 31, 2011. The Company requires cash for financing its receivables and inventories, paying operating expenses and capital expenditures, and for dividends. The Company meets its liquidity needs and finances its capital expenditures from its available cash and funds provided by operations along with borrowings under three credit arrangements that are described below.

The Company believes its current cash resources, projected operating cash flow, and remaining capacity under its bank lines of credit are sufficient to cover all of its expected working capital needs, planned capital expenditures, dividends, and other cash requirements, excluding potential acquisitions. The Company has permanently reinvested cash and cash equivalents in its foreign operations of $13.9 million and $6.6 million as of May 31, 2012 and 2011, respectively, and does not expect these contributions to have a significant impact on the Company’s overall liquidity.

Net working capital was $211.6 million at May 31, 2012, as compared with $172.3 million at May 31, 2011. The increase in net working capital mainly resulted from increased cash from earnings over the past year, increased inventory to support the increases in sales, especially in the irrigation segment, and increased receivables due to higher sales. Cash flows provided by operations totaled $25.9 million during the nine months ended May 31, 2012 compared to $28.3 million provided by operations during the same prior year period. Cash provided by operations decreased by $2.4 million compared to the prior year period primarily as a result of an increase in the amount of inventories.

Cash flows used in investing activities totaled $6.2 million during the nine months ended May 31, 2012 compared to cash flows used in investing activities of $7.8 million during the same prior year period. Capital spending of $7.6 million in fiscal 2012 increased compared to the prior year capital spending of $5.3 million. The decrease in the net cash used in investing activities was primarily due to the gain proceeds from the settlement of net investment hedges in 2012 and due to the impact of an acquisition that occurred during the first quarter of fiscal 2011.

Cash flows used in financing activities totaled $6.6 million during the nine months ended May 31, 2012 compared to cash flows used in financing activities of $3.9 million during the same prior year period. The Company’s total interest-bearing debt decreased from $9.6 million at May 31, 2011 to $5.4 million at May 31, 2012 due to quarterly principal payments. The remaining $5.4 million of interest-bearing debt at May 31, 2012 is scheduled to be paid by June 10, 2013. The $2.7 million increase in cash used in financing activities was primarily due to a $1.5 million increase in share-based compensation activities and a decrease of $1.2 million in the net borrowing on the revolving line of credit.

Euro Line of Credit

The Company’s wholly-owned European subsidiary, Lindsay Europe, has an unsecured revolving line of credit with Societe Generale, a European commercial bank, under which it could borrow for working capital purposes up to 2.3 million Euros, which equates to approximately USD $2.9 million as of May 31, 2012 (the “Euro Line of Credit”). On January 23, 2012, the Company extended the Euro Line of Credit with Societe Generale through January 31, 2013. There were no borrowings outstanding on this credit agreement at May 31, 2012 and August 31, 2011. There was $1.3 million outstanding on this credit agreement at May 31, 2011. Under the terms of the Euro Line of Credit, borrowings, if any, bear interest at a floating rate in effect from time to time designated by the commercial bank as the Euro Interbank Offered Rate plus 110 basis points (1.78 percent at May 31, 2012). Unpaid principal and interest is due by January 31, 2013.

BSI Term Note

The Company entered into an unsecured $30.0 million Term Note and Credit Agreement, effective June 1, 2006, with Wells Fargo Bank, N.A. (the “BSI Term Note”) to partially finance the acquisition of BSI. Borrowings under the BSI Term Note bear interest at a rate equal to LIBOR plus 50 basis points. The Company in prior years fixed the rate at 6.05 percent through an interest rate swap as described in Note 8 to the condensed consolidated financial statements. Principal is repaid quarterly in equal payments of $1.1 million over a seven-year period that began in September of 2006. The BSI Term Note is due June 10, 2013.

- 21

Revolving Credit Agreement

The Company has an unsecured $30.0 million Revolving Credit Note and Credit Agreement with Wells Fargo Bank, N.A. (the “Revolving Credit Agreement”). The Revolving Credit Agreement was amended on January 23, 2011 in order to extend the termination date from January 23, 2012 to January 23, 2014. The borrowings from the amended Revolving Credit Agreement will primarily be used for working capital purposes and funding acquisitions. At May 31, 2012 and 2011 and August 31, 2011, there was no outstanding balance on the Revolving Credit Agreement. Borrowings under the Revolving Credit Agreement bear interest at a rate equal to LIBOR plus 105 basis points, subject to adjustment as set forth in the Revolving Credit Agreement as amended. Interest is paid on a monthly to quarterly basis depending on loan type. The Company also pays an annual commitment fee of 0.25 percent on the unused portion of the amended Revolving Credit Agreement. Unpaid principal and interest is due by January 23, 2014.

The BSI Term Note and the Revolving Credit Agreement (collectively, the “Notes”) each contain the same covenants, including certain covenants relating to the Company’s financial condition. These include maintaining a funded debt to EBITDA ratio, a fixed charge coverage ratio, a current ratio and a tangible net worth requirement (all as defined in the Notes) at specified levels. Upon the occurrence of any event of default of these covenants specified in the Notes, including a change in control of the Company (as defined in the Notes), all amounts due thereunder may be declared to be immediately due and payable. At May 31, 2012 and 2011 and August 31, 2011, the Company was in compliance with all loan covenants.

Contractual Obligations and Commercial Commitments

There have been no material changes in the Company’s contractual obligations and commercial commitments as described in the Company’s Annual Report on Form 10-K for the fiscal year ended August 31, 2011.

Market Conditions and Fiscal 2012 Outlook

Farm incomes and commodity prices remain relatively high by historical standards and have continued to drive positive farmer sentiment. While the USDA projects U.S. 2012 Net Farm Income to be the second highest on record, it is predicted to be 28 percent higher than the ten year average, continuing to represent positive economic conditions for U.S. farmers. The U.S. federal government is currently examining the level of farm subsidies and tax credits. Changes to these programs could have an impact on commodity prices and irrigation equipment demand. Demand for Lindsay’s irrigation equipment is closely aligned with net farm income and commodity prices and can fluctuate significantly on a quarterly or annual basis. The Company believes the most significant opportunities for growth over the next several years are in international markets, where irrigation use is significantly less developed, and demand is driven by food security, water scarcity and population growth.

Infrastructure demand, including for QMB^® system projects, has proven to be challenging due to funding issues and project delays. The infrastructure segment continues to experience revenue and profit volatility due to the project nature of the QMB^® systems and the fixed nature of some operating expenses. The QMB^® system project delays have not significantly changed the Company’s perspective on the likelihood of the specific projects or the future demand for QMB^® systems. The outlook for government funded infrastructure spending remains challenging due to global governmental budget constraints and uncertainty on timing of a multi-year U.S. highway bill. The Company is confident in the opportunity for QMB^® systems to drive significant profitability over the long term as a superior solution to worldwide traffic congestion, lost productivity and energy waste. Demand for the Company’s transportation safety products continues to be driven by population growth and the need for improved road safety.

- 22

As of May 31, 2012, the Company has an order backlog of $44.5 million compared with $43.3 million at May 31, 2011 and $87.3 million at February 29, 2012. The Company’s backlog can fluctuate from period to period due to the seasonality, cyclicality, timing and execution of contracts. Typically, the Company’s backlog at any point in time represents only a portion of the revenue it expects to realize during the following three month period. However, the timing related to certain project oriented contracts may extend longer than three months.

For the business overall, the global, long-term drivers of water conservation, population growth, increasing importance of biofuels, and the need for safer, more efficient transportation solutions remain positive. In addition to the overall business enhancements that have taken place, the Company continues to have an ongoing, structured, acquisition process that is expected to generate additional growth opportunities throughout the world in water and infrastructure. Lindsay is committed to achieving earnings growth through global market expansion, improvements in margins, and strategic acquisitions.

Recently Issued Accounting Pronouncements

In May 2011, the Financial Accounting Standards Board (FASB) issued ASU No. 2011-04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs, which requires the categorization by level for items that are only required to be disclosed at fair value and information about transfers between Level 1 and Level 2. In addition, the ASU provides guidance on measuring the fair value of financial instruments managed within a portfolio and the application of premiums and discounts on fair value measurements. The ASU requires additional disclosure for Level 3 measurements regarding the sensitivity of fair value to changes in unobservable inputs and any interrelationships between those inputs. The guidance is effective for fiscal years beginning after December 15, 2011. The Company does not expect the adoption of this standard to impact its condensed consolidated financial statements.

In June 2011, the FASB issued ASU No. 2011-05, Presentation of Comprehensive Income, which amends ASC 220, Comprehensive Income, by requiring all nonowner changes in shareholders’ equity be presented either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The guidance is effective retrospectively for fiscal years and interim periods within those years beginning after December 15, 2011. In December 2011, the FASB issued ASU No. 2011-12, Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05, which defers certain portions of ASU No. 2011-05 indefinitely and will be further deliberated by the FASB at a future date. The Company is currently evaluating the impact of the adoption of the guidance on its condensed consolidated financial statements.

In September 2011, the FASB issued ASU No. 2011-08, Intangibles — Goodwill and Other. ASU No. 2011-08 allows entities to first assess qualitatively whether it is necessary to perform the two-step goodwill impairment test. If an entity believes, as a result of its qualitative assessment, that it is more likely than not that the fair value of a reporting period is less than its carrying amount, the quantitative two-step goodwill impairment test is required. An entity has the unconditional option to bypass the qualitative assessment and proceed directly to performing the first step of the goodwill impairment test. The guidance is effective for annual and interim impairment tests for fiscal years beginning after December 15, 2011. The Company does not expect the adoption of this standard to impact its condensed consolidated financial statements.

ITEM 3 – Quantitative and Qualitative Disclosures About Market Risk

The Company uses certain financial derivatives to mitigate its exposure to volatility in interest rates and foreign currency exchange rates. The Company uses these derivative instruments to hedge exposures in the ordinary course of business and does not invest in derivative instruments for speculative purposes. The credit risk under these interest rate and foreign currency agreements is not considered to be significant. The Company attempts to manage market and credit risks associated with its derivative instruments by establishing and monitoring limits as to the types and degree of risk that may be undertaken, and by entering into transactions with high-quality counterparties. As of May 31, 2012, the Company’s derivative counterparty had investment grade credit ratings.

The Company has manufacturing operations in the United States, France, Brazil, Italy and China. The Company has sold products throughout the world and purchases certain of its components from third-party international suppliers. Export sales made from the United States are principally U.S. dollar denominated. At times, export sales may be denominated in a currency other than the U.S. dollar. A majority of the Company’s revenue generated from operations outside the United States is denominated in local currency. Accordingly, these sales are not typically subject to significant foreign currency transaction risk. The Company’s most significant transactional foreign currency exposures are the Euro, the Brazilian real, the South African rand and the Chinese renminbi in relation to the U.S. dollar. Fluctuations in the value of foreign currencies create exposures, which can adversely affect the Company’s results of operations. Based on the consolidated statement of operations for the three months ended May 31, 2012, the Company estimates the potential decrease in operating income from a 10% adverse change in the underlying exchange rates, in U.S. dollar terms, would be less than $1.0 million.

In order to reduce exposures related to changes in foreign currency exchange rates, the Company, at times, may enter into forward exchange or option contracts for transactions denominated in a currency other than the functional currency for certain of its operations. This activity primarily relates to economically hedging against foreign currency risk in purchasing inventory, sales of finished goods, and future settlement of foreign denominated assets and liabilities. The Company had $2.3 million of U.S. dollar equivalent cash flow forward exchange contracts and option contracts outstanding as of May 31, 2012.

In order to reduce translation exposure resulting from translating the financial statements of its international subsidiaries into U.S. dollars, the Company, at times, utilizes Euro foreign currency forward contracts to hedge a portion of its Euro net investment exposure in its foreign operations. At May 31, 2012, the Company had outstanding Euro foreign currency forward contracts to sell 22.5 million Euro at fixed prices expected to settle during the fourth quarter of fiscal 2012. Based on the net investments contracts outstanding at May 31, 2012, the Company estimates the potential decrease in fair value from a 10% adverse change in the underlying exchange rates, in U.S. dollar terms, would be approximately $2.8 million. This decrease in fair value would be reflected as a reduction to other comprehensive income offsetting the translation exposure of the international subsidiaries.

In order to reduce interest rate risk on the $30 million BSI Term Note, the Company has entered into an interest rate swap agreement with Wells Fargo Bank, N.A. that is designed to convert the variable interest rate on the entire amount of this borrowing to a fixed rate of 6.05 percent per annum. Under the terms of the interest rate swap, the Company receives variable interest rate payments and makes fixed interest rate payments on an amount equal to the outstanding balance of the BSI Term Note, thereby creating the equivalent of fixed-rate debt.

ITEM 4 – Controls and Procedures

The Company carried out an evaluation under the supervision and the participation of the Company’s management, including the Company’s Chief Executive Officer (CEO) and Chief Financial Officer (CFO), of the effectiveness of the design and operation of the Company’s disclosure controls and procedures pursuant to Exchange Act Rules 13a-15(e) and 15d-15(e). Based upon that evaluation, the CEO and CFO concluded that the Company’s disclosure controls and procedures were effective as of May 31, 2012.

Additionally, the CEO and CFO determined that there has not been any change to the Company’s internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) during the last fiscal quarter that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

Part II – OTHER INFORMATION

ITEM 1 – Legal Proceedings

In the ordinary course of its business operations, the Company is involved, from time to time, in commercial litigation, employment disputes, administrative proceedings, and other legal proceedings. None of these proceedings, individually or in the aggregate, is expected to have a material effect on the business or financial condition of the Company.

Environmental Matters

In 1992, the Company entered into a consent decree with the Environmental Protection Agency of the United States Government (the “EPA”) in which the Company committed to remediate environmental contamination of the groundwater that was discovered in 1982 through 1990 at and adjacent to its Lindsay, Nebraska facility (the “site”). The site was added to the EPA’s list of priority superfund sites in 1989. Between 1993 and 1995, remediation plans for the site were approved by the EPA and fully implemented by the Company. Since 1998, the primary remaining contamination at the site has been the presence of volatile organic chemicals in the groundwater. The remediation process consists of drilling wells into the aquifer and pumping water to the surface to allow these contaminants to be removed by aeration. The Company accrues the anticipated cost of remediation when the obligation is probable and can be reasonably estimated.

In 2008, the Company and the EPA conducted their periodic five-year review of the status of the remediation of the contamination of the site. In response to the review, the Company and its environmental consultants have developed a remedial action work plan. In the first quarter of fiscal 2012, the Company undertook an investigation to assess further potential site remediation and containment actions. In connection with the receipt of preliminary results of this investigation and other evaluations, the Company estimated that it would incur $7.2 million in remediation and operating costs and accrued that undiscounted amount as an operating expense in the first quarter of fiscal 2012.

Although the Company has accrued all reasonably estimable costs associated with remediation of the site, it is expected that additional testing and environmental monitoring and remediation will be required in the future as part of the Company’s ongoing discussions with the EPA regarding the development and implementation of the remedial action plans, which could result in changes to its estimates. In addition, the current investigation has not yet been completed and does not include all affected areas on the site. Estimates continue to be refined and evaluated on a number of remediation alternatives and the EPA has not provided approval of possible action plans. While additional estimated expenses could significantly exceed the amount accrued as of May 31, 2012 and could be material to the operating results of any fiscal quarter or fiscal year, the Company does not expect that such additional expenses would have a material adverse effect on its liquidity or financial condition.

The following table summarizes the undiscounted environmental remediation liability classifications included in the balance sheet as of May 31, 2012 and 2011 and August 31, 2011:

Environmental Remediation Liabilities
$ in thousands	May 31,		May 31,		August 31,

ITEM 2 – Unregistered Sales of Equity Securities and Use of Proceeds

The Company made no repurchases of its common stock under the Company’s stock repurchase plan during the quarter ended May 31, 2012; therefore, tabular disclosure is not presented. From time to time, the Company’s Board of Directors has authorized the Company to repurchase shares of the Company’s common stock. Under this share repurchase plan, the Company has existing authorization to purchase, without further announcement, up to 881,139 shares of the Company’s common stock in the open market or otherwise.

Condensed Consolidated Financial Statements [Abstract]

Condensed Consolidated Financial Statements

(1)Condensed Consolidated Financial Statements

The condensed consolidated financial statements are presented in accordance with the rules and regulations of the Securities and Exchange Commission (SEC) and do not include all of the disclosures normally required by U.S. generally accepted accounting principles as contained in Lindsay Corporation’s (the “Company”) Annual Report on Form 10-K.Accordingly, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s latest Annual Report on Form 10-K for the fiscal year ended August 31, 2011.

In the opinion of management, the condensed consolidated financial statements of the Company reflect all adjustments (consisting of only normal recurring accruals) necessary to present fairly the financial position and the results of operations and cash flows for the periods presented.The results for interim periods are not necessarily indicative of trends or results expected by the Company for a full year.

The condensed consolidated financial statements were prepared using accounting principles generally accepted in the United States. These principles require us to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities and the reported amounts of revenues and expenses. Actual results could differ from these estimates. Certain reclassifications have been made to prior financial statements and notes to conform to the current year presentation.

Net Earnings Per Share [Abstract]

Net Earnings Per Share

(2)Net Earnings per Share

Basic net earnings per share is computed using the weighted-average number of common shares outstanding during the period. Diluted net earnings per share is computed using the weighted-average number of common shares outstanding plus dilutive potential common shares outstanding during the period.

Employee stock options, nonvested shares and similar equity instruments granted by the Company are treated as potential common share equivalents outstanding in computing diluted net earnings per share. The Company’s diluted common shares outstanding reported in each period includes the dilutive effect of restricted stock units, in-the-money options, and performance stock units for which threshold performance conditions have been satisfied and is calculated based on the average share price for each fiscal period using the treasury stock method.

The following table shows the securities excluded from the computation of earnings per share since their inclusion would have been anti-dilutive:

	Three months ended		Nine months ended
	May 31,		May 31,
	2012	2011	2012	2011
Restricted stock units	-	-	4,322	2,750
Stock options	34,971	-	27,805	-

Performance stock units are excluded from the calculation of dilutive potential common shares until the threshold performance conditions have been satisfied.At May 31, 2012, the threshold performance conditions for the November 12, 2009 grants had been satisfied resulting in the inclusion of 37,746 performance stock units in the calculation of diluted net earnings per share. At May 31, 2012 and 2011, there were 43,388 and 98,625, respectively, of performance stock units excluded from the calculation of diluted net earnings per share because the threshold performance conditions had not been satisfied.

Share-Based Compensation

(14)Share-Based Compensation

The Company measures and recognizes compensation expense for all share-based payment awards made to employees and directors based on estimated fair values. The value of the portion of the award that is ultimately expected to vest is recognized as expense in the Company’s condensed consolidated statement of operations over the periods during which the employee or director is required to perform a service in exchange for the award.The Company’s current share-based compensation plan, approved by the stockholders of the Company, provides for awards of stock options, restricted shares, restricted stock units, stock appreciation rights, performance shares and performance stock units to employees and non-employee directors of the Company.In connection with the restricted stock units, performance stock units and stock options, the Company is accruing compensation expense based on the estimated number of shares expected to be issued utilizing the most current information available to the Company at the date of the financial statements.Share-based compensation expense was $0.8 million and $0.8 million for the three months ended May 31, 2012 and 2011, respectively.Share-based compensation expense was $2.6 million and $2.4 million for the nine months ended May 31, 2012 and 2011, respectively.

Commitments And Contingencies

(10) Commitments and Contingencies

In 1992, the Company entered into a consent decree with the Environmental Protection Agency of the United States Government (the “EPA”) in which the Company committed to remediate environmental contamination of the groundwater that was discovered in 1982 through 1990 at and adjacent to its Lindsay, Nebraska facility (the “site”).The site was added to the EPA’s list of priority superfund sites in 1989.Between 1993 and 1995, remediation plans for the site were approved by the EPA and fully implemented by the Company.Since 1998, the primary remaining contamination at the site has been the presence of volatile organic chemicals in the groundwater.The remediation process consists of drilling wells into the aquifer and pumping water to the surface to allow these contaminants to be removed by aeration. The Company accrues the anticipated cost of remediation when the obligation is probable and can be reasonably estimated.

In 2008, the Company and the EPA conducted their periodic five-year review of the status of the remediation of the contamination of the site. In response to the review, the Company and its environmental consultants have developed a remedial action work plan. In the first quarter of fiscal 2012, the Company undertook an investigation to assess further potential site remediation and containment actions.In connection with the receipt of preliminary results of this investigation and other evaluations, the Company estimated that it would incur $7.2 million in remediation and operating costs and accrued that undiscounted amount as an operating expense in the first quarter of fiscal 2012.

Although the Company has accrued all reasonably estimable costs associated with remediation of the site, it is expected that additional testing and environmental monitoring and remediation will be required in the future as part of the Company’s ongoing discussions with the EPA regarding the development and implementation of the remedial action plans, which could result in changes to its estimates.In addition, the current investigation has not yet been completed and does not include all affected areas on the site.Estimates continue to be refined and evaluated on a number of remediation alternatives and the EPA has not provided approval of possible action plans.While additional estimated expenses could significantly exceed the amount accrued as of May 31, 2012 and could be material to the operating results of any fiscal quarter or fiscal year, the Company does not expect that such additional expenses would have a material adverse effect on its liquidity or financial condition.

The following table summarizes the undiscounted environmental remediation liability classifications included in the balance sheet as of May 31, 2012 and 2011 and August 31, 2011:

Financial Derivatives [Abstract]

Financial Derivatives

(8) Financial Derivatives

The Company uses certain financial derivatives to mitigate its exposure to volatility in interest rates and foreign currency exchange rates.The Company uses these derivative instruments to hedge exposures in the ordinary course of business and does not invest in derivative instruments for speculative purposes.Each derivative is designated as a cash flow hedge, a hedge of a net investment, or remains undesignated.The Company records the fair value of these derivative instruments on the balance sheet.For the instruments that are designated as a cash flow hedge and meet certain documentary and analytical requirements to qualify for hedge accounting treatment, changes in the fair value for the effective portion are reported in other comprehensive income (“OCI”), net of related income tax effects, and are reclassified to the income statement when the effects of the item being hedged are recognized in the income statement.Changes in fair value of derivative instruments that qualify as hedges of a net investment in foreign operations are recorded as a component of accumulated currency translation adjustment in accumulated other comprehensive income (“AOCI”), net of related income tax effects.Changes in the fair value of undesignated hedges are recognized currently in the income statement as other income (expense).All changes in derivative fair values due to ineffectiveness are recognized in earnings.

The Company manages market and credit risks associated with its derivative instruments by establishing and monitoring limits as to the types and degree of risk that may be undertaken, and by entering into transactions with high-quality counterparties. As of May 31, 2012, the Company’s derivative counterparty had investment grade credit ratings.

Financial derivatives consist of the following:

	Fair Values of Derivative Instruments

Total derivatives not designated as hedging instruments		$	116	$	-	$	-

In addition, accumulated other comprehensive income included realized and unrealized gains, net of related income tax effects, of $2.7 million, $0.4 million and $0.5 million at May 31, 2012 and 2011 and August 31, 2011, respectively, related to derivative contracts designated as hedging instruments.

Cash Flow Hedging Relationships

In order to reduce interest rate risk on the BSI Term Note, the Company entered into an interest rate swap agreement with Wells Fargo Bank, N.A. that is designed to convert the variable interest rate on the entire amount of the borrowing to a fixed rate of 6.05 percent per annum.Under the terms of the interest rate swap, the Company receives variable interest rate payments and makes fixed interest rate payments on an amount equal to the outstanding balance of the BSI Term Note.Changes in the fair value of the interest rate swap designated as a hedging instrument that effectively offset the variability of cash flows associated with variable-rate, long-term debt obligations are reported in AOCI, net of related income tax effects.

In order to reduce exposures related to changes in foreign currency exchange rates, the Company, at times, may enter into forward exchange or option contracts for transactions denominated in a currency other than the functional currency for certain of its operations. This activity primarily relates to economically hedging against foreign currency risk in purchasing inventory, sales of finished goods, and future settlement of foreign denominated assets and liabilities. Changes in the fair value of the forward exchange contracts or option contracts designated as hedging instruments that effectively offset the hedged risks are reported in AOCI, net of related income tax effects.The Company had $2.3 million, $1.1 million, and $0.7 million of U.S. dollar equivalent cash flow forward exchange contracts and option contracts outstanding as of May 31, 2012 and 2011, and August 31, 2011, respectively. In addition, the amount of gain or loss recognized in OCI, the amount of gain or loss reclassified from AOCI into income and the amount of gain or loss recognized in income related to the outstanding cash flow hedging relationships were immaterial.

Net Investment Hedging Relationships

In order to reduce translation exposure resulting from translating the financial statements of its international subsidiaries into U.S. dollars, the Company, at times, utilizes Euro foreign currency forward contracts to hedge a portion of its Euro net investment exposure in its foreign operations.These foreign currency forward contracts qualify as a hedge of net investments in foreign operations.Changes in fair value of the net investment hedge contracts are reported in OCI as part of the currency translation adjustment, net of tax.

For the three and nine months ended May 31, 2012, the Company settled Euro foreign currency forward contracts resulting in after-tax net loss (gain) of $0.2 million and ($0.8) million, respectively, which were included in OCI as part of a currency translation adjustment.For the three and nine months ended May 31, 2011, the Company settled Euro foreign currency forward contracts resulting in after-tax net loss of $0.3 million and $0.7 million, respectively, which were included in OCI as part of a currency translation adjustment.

There were no amounts recorded in the condensed consolidated statement of operations related to ineffectiveness of Euro foreign currency forward contracts for the three and nine months ended May 31, 2012 and 2011. Accumulated currency translation adjustments in AOCI at May 31, 2012 and 2011 and August 31, 2011 reflected realized and unrealized after-tax gains of $2.7 million, $0.8 million and $0.9 million, respectively.

At May 31, 2012 and 2011 and August 31, 2011, the Company had outstanding Euro foreign currency forward contracts to sell 22.5 million Euro, 10.0 million Euro and 10.0 million Euro, respectively, at fixed prices to settle during the next fiscal quarter. The Company’s foreign currency forward contracts qualify as hedges of a net investment in foreign operations.

The carrying amount of long-term debt (including current portion) was $5.4 million, $9.6 million and $8.6 million as of May 31, 2012 and 2011 and August 31, 2011, respectively.  The fair value of this debt was estimated at $5.3 million, $9.5 million, and $8.5 million as of May 31, 2012 and 2011 and August 31, 2011, respectively. Fair value of long-term debt (including current portion) is estimated by discounting the future estimated cash flows of each instrument at current market interest rates for similar debt instruments of comparable maturities and credit quality.

The Company also measures the fair value of certain assets on a non-recurring basis, generally quarterly, annually, or when events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. These assets include fixed assets, goodwill, and other intangible assets. There were no required fair value adjustments for assets and liabilities measured at fair value on a non-recurring basis for the three and nine months ended May 31, 2012 and 2011.

Inventories

(5)Inventories

Inventories are stated at the lower of cost or market. Cost is determined by the last‑in, first‑out (LIFO) method for the Company’s Lindsay, Nebraska inventory and its two warehouses in Idaho and Texas. Cost is determined by the first-in, first-out (FIFO) method for inventory at the Company’s Omaha, Nebraska warehouse, and at operating locations in California, Wisconsin, China and Australia.Cost is determined by the weighted average cost method for inventory at the Company’s other operating locations in Washington State, France, Brazil, Italy, and South Africa.The Company reserves for obsolete, slow moving, and excess inventory by estimating the net realizable value based on potential future use of such inventory.
