PART I

ITEM 1 – Business

INTRODUCTION

Lindsay Corporation, along with its subsidiaries (collectively called “Lindsay” or the “Company”), is a global leader in providing a variety of proprietary water management and road infrastructure products and services. The Company has been involved in the manufacture and distribution of agricultural equipment since 1955 and has grown from a regional company to an international agribusiness and highway infrastructure firm with worldwide sales and distribution. Lindsay, a Delaware corporation, maintains its corporate offices in Omaha, Nebraska. The Company has operations which are categorized into two major reporting segments. Industry segment information about Lindsay is included in Note O to the consolidated financial statements.

Irrigation Segment – The Company’s irrigation segment includes the manufacture and marketing of center pivot, lateral move, and hose reel irrigation systems which are used principally in the agricultural industry to increase or stabilize crop production while conserving water, energy, and labor. The irrigation segment also manufactures and markets repair and replacement parts for its irrigation systems and controls, and designs, manufactures and services water pumping stations and controls for the agriculture, golf, landscape and municipal markets. The Company continues to strengthen irrigation product offerings through innovative technology such as GPS positioning and guidance, variable rate irrigation, wireless irrigation management, and smartphone applications. The Company’s principal irrigation manufacturing facilities are located in Lindsay, Nebraska and Hartland, Wisconsin. Internationally, the Company has production operations in France, Brazil and China as well as distribution operations in South Africa, Australia and New Zealand. The Company also exports some of its equipment from the U.S. to other international markets.

Infrastructure Segment – The Company’s infrastructure segment includes the manufacture and marketing of moveable barriers, specialty barriers, crash cushions and end terminals, road marking and road safety equipment, large diameter steel tubing, railroad signals and structures, and outsourced manufacturing services. The principal infrastructure manufacturing facilities are located in Rio Vista, California, Milan, Italy, and Omaha, Nebraska.

PRODUCTS BY SEGMENT

IRRIGATION SEGMENT

Products – The Company manufactures and markets its center pivot and lateral move irrigation systems in the U.S. and internationally under its Zimmatic^® brand. The Company also manufactures and markets separate lines of center pivot and lateral move irrigation equipment for use on smaller fields under its Greenfield^® brand, and hose reel travelers under the Perrot™ and Greenfield^® brands in Europe and South Africa. The Company also produces or markets irrigation controls, chemical injection systems and remote monitoring and control systems which it sells under its GrowSmart^® brand. In addition to whole systems, the Company manufactures and markets repair and replacement parts for its irrigation systems and controls. The Company also designs, manufactures and services water pumping stations and controls for the agriculture, golf, landscape and municipal markets.

The Company’s irrigation systems are primarily of the standard sized center pivot type, with a small portion of its products consisting of the lateral move type. Both are automatic, continuous move systems consisting of sprinklers mounted on a water carrying pipeline which is supported approximately 11 feet off the ground by a truss system suspended between moving towers.

A typical center pivot is approximately 1,300 feet long and is designed to circle within a quarter-section of land, which comprises 160 acres, wherein it irrigates approximately 130 to 135 acres. A center pivot or lateral move system can also be custom designed and can irrigate from 25 to 600+ acres.

3

A center pivot system represents a significant investment to a farmer. In a dry land conversion to center pivot irrigation, approximately one-half of the investment is for the pivot itself and the remainder is attributable to installation of additional equipment such as wells, pumps, underground water pipes, electrical supply and a concrete pad upon which the pivot is anchored. The Company’s center pivot and lateral move irrigation systems can be enhanced with a family of integrated plug-and-play add-ons such as water pumping station controls.

The Company also manufactures and distributes hose reel travelers. Hose reel travelers are typically deployed in smaller or irregular fields and usually are easy to operate, easy to move from field to field, and a lower investment than a typical standard center pivot.

The Company also markets pivot monitoring and control systems, which include remote telemetry and a web or personal computer hosted data acquisition and monitoring application. These systems allow growers to monitor their pivot system, accumulate data on the operation of the system, and control the pivot from a remote location by logging onto an internet web site. The pivot monitoring and control systems are marketed under the FieldNET^® product name.

Other Types of Irrigation – Center pivot and lateral move irrigation systems compete with three other types of irrigation: flood, drip, and other mechanical devices such as hose reel travelers and solid set sprinklers. The bulk of the worldwide irrigation is accomplished by the traditional method of flood irrigation. Flood irrigation is accomplished by either flooding an entire field, or by providing a water source (ditches or a pipe) along the side of a field, which is planed and slopes slightly away from the water source. The water is released to the crop rows through gates in the ditch or pipe, or through siphon tubes arching over the ditch wall into some of the crop rows. It runs down through the crop row until it reaches the far end of the row, at which time the water source is moved and another set of rows are flooded. A significant disadvantage or limitation of flood irrigation is that it cannot be used to irrigate uneven, hilly, or rolling terrain or fields. In “drip” or “low flow” irrigation, perforated plastic pipe or tape is installed on the ground or buried underground at the root level. Several other types of mechanical devices, such as hose reel travelers, irrigate the remaining irrigated acres.

Center pivot, lateral move, and hose reel traveler irrigation offers significant advantages when compared with other types of irrigation. It requires less labor and monitoring; can be used on sandy ground, which, due to poor water retention ability, must have water applied frequently; can be used on uneven ground, thereby allowing previously unsuitable land to be brought into production; can also be used for the application of fertilizers, insecticides, herbicides, or other chemicals (termed “fertigation” or “chemigation”); and conserves water and chemicals through precise control of the amount and timing of the application.

Markets – Water is an essential and critical requirement for crop production, and the extent, regularity, and frequency of water application can be a critical factor in crop quality and yield. The fundamental factors which govern the demand for center pivot and lateral move systems are essentially the same in both the U.S. and international markets. Demand for center pivot and lateral move systems is determined by whether the value of the increased crop production attributable to center pivot or lateral move irrigation exceeds any increased costs associated with purchasing, installing, and operating the equipment. Thus, the decision to purchase a center pivot or lateral move system, in part, reflects the profitability of agricultural production, which is determined primarily by the prices of agricultural commodities and other farming inputs.

The current demand for center pivot systems has three sources: conversion to center pivot systems from less water efficient, more labor intensive types of irrigation; replacement of older center pivot systems, which are beyond their useful lives or are technologically obsolete; and conversion of dry land farming to irrigated farming. In addition, demand for center pivots and lateral move irrigation equipment depends upon the need for the particular operational characteristics and advantages of such systems in relation to alternative types of irrigation, primarily flood. More efficient use of the basic natural resources of land, water, and energy helps drive demand for center pivot and lateral move irrigation equipment. Increasing global population not only increases demand for agricultural output, but also places additional and competing demands on land, water, and energy. The Company expects demand for center pivots and lateral move systems to continue to increase relative to other irrigation methods because center pivot and lateral move systems are preferred where the soil is sandy, the terrain is not flat, the land area to be irrigated is sizeable; there is a shortage of reliable labor; water supply is restricted and conservation is critical; and/or fertigation or chemigation will be utilized.

4

United States Market – In the United States, the Company sells its branded irrigation systems, including Zimmatic^®, to over 200 independent dealer locations, who resell to their customer, the farmer. Dealers assess their customer’s requirements, assemble and erect the system in the field, and provide additional system components, primarily relating to water supply (wells, pumps, pipes) and electrical supply (on-site generation or hook-up to power lines). Lindsay dealers generally are established local agribusinesses, many of which also deal in related products, such as well drilling and water pump equipment, farm implements, grain handling and storage systems, and farm structures.

International Market – Over the years, the Company has sold center pivot and lateral move irrigation systems throughout the world. The Company has production and sales operations in France, Brazil and China as well as distribution and sales operations in South Africa, Australia and New Zealand and sales operations in Central America and the Middle East serving the key European, South American, Chinese, African, Australian, New Zealand, Central American and Middle Eastern markets, respectively. The Company also exports some of its equipment from the U.S. to other international markets. The majority of the Company’s U.S. export sales is denominated in U.S. dollars and is shipped against prepayments or U.S. bank confirmed irrevocable letters of credit or other secured means.

The Company’s international markets differ with respect to the need for irrigation, the ability to pay, demand, customer type, government support of agriculture, marketing and sales methods, equipment requirements, and the difficulty of on-site erection. The Company’s industry position is such that it believes that it will likely be considered as a potential supplier for most major international agricultural development projects utilizing center pivot or lateral move irrigation systems.

Competition – The U.S. center pivot irrigation system industry has seen significant consolidation of manufacturers over the years; four primary U.S. manufacturers remain today. The international market includes participation and competition by the leading U.S. manufacturers as well as certain regional manufacturers. The Company competes in certain product lines with several manufacturers, some of whom may have greater financial resources than the Company. The Company competes by continuously improving its products through ongoing research and development activities. The Company continues to strengthen irrigation product offerings through innovative technology such as GPS positioning and guidance, variable rate irrigation, wireless irrigation management, and smartphone applications. The Company’s engineering and research expenses related to irrigation totaled approximately $6.0 million, $6.1 million, and $4.1 million for fiscal years 2012, 2011, and 2010, respectively. Competition also occurs in areas of price and seasonal programs, product quality, durability, controls, product characteristics, retention and reputation of local dealers, customer service, and, at certain times of the year, the availability of systems and their delivery time. The Company believes it competes favorably with respect to all of these factors.

INFRASTRUCTURE SEGMENT

Products – Quickchange^® Moveable Barrier™– The Company’s Quickchange^® Moveable Barrier™ (“QMB^®”) system is composed of three parts: 1) T-shaped concrete barriers that are connected to form a continuous wall, 2) a Barrier Transfer Machine™ (“BTM™”) capable of moving the barrier laterally across the pavement, and 3) the variable length barriers necessary for accommodating curves. A barrier element is approximately 32 inches high, 13-24 inches wide, 3 feet long and weighs 1,500 pounds. The barrier elements are interconnected by very heavy duty steel hinges to form a continuous barrier. The BTM™ employs an inverted S-shaped conveyor mechanism that lifts the barrier, moving it laterally before setting it back on the roadway surface.

In permanent applications, the QMB^® systems increase capacity and reduce congestion by varying the number of traffic lanes to match the traffic demand. Roadways with fixed medians have a set number of lanes in each direction and cannot adjust to traffic demands that may change over the course of a day, or to capacity reductions caused by traffic incidents or road repair and maintenance. Applications include high volume highways where expansion may not be feasible due to lack of additional right-of-way, environmental concerns, or insufficient funding. The QMB^® system is particularly useful in busy commuter corridors and at choke points such as bridges and tunnels. QMB^® systems can also be deployed at roadway or roadside construction sites to accelerate construction, improve traffic flow and safeguard work crews and motorists by positively separating the work area and traffic. Examples of types of work completed with the help of a QMB^® system include highway reconstruction, paving and resurfacing, road widening, median and shoulder construction, and repairs to tunnels and bridges.

5

The Company offers a variety of equipment lease options for QMB^® systems and BTM™ equipment used in construction applications. The leases extend for periods of three months or more for equipment already existing in the Company’s lease fleet. Longer lease periods may be required for specialty equipment that must be built for specific projects.

These systems have been in use since 1987. Significant progress has been made introducing the products into international markets in recent years. Typical sales for a highway safety or road improvement project range from $2.0-$20.0 million, making them significant capital investments.

Crash Cushions and End Terminals – The Company offers a complete line of redirective and non-redirective crash cushions which are used to enhance highway safety at locations such as toll booths, freeway off-ramps, medians and roadside barrier ends, bridge supports, utility poles and other fixed roadway hazards. The Company’s primary crash cushion products cover a full range of lengths, widths, speed capacities and application accessories and include the following brand names: TAU^®, Universal TAU-II^®, TAU-II-R™, TAU-B_NR™, ABSORB 350^® and Walt™. In addition to these products the Company also offers guardrail end terminal products such as the X-Tension™ and TESI^® systems. The crash cushions and end terminal products compete with other vendors in the world market. These systems are generally sold through a distribution channel that is domiciled in particular geographic areas.

Specialty Barriers – The Company also offers specialty barrier products such as the SAB™, ArmorGuard™, PaveGuard™ and DR46™ portable barrier and/or barrier gate systems. These products offer portability and flexibility in setting up and modifying barriers in work areas and provide quick opening, high containment gates for use in median or roadside barriers. The gates are generally used to create openings in barrier walls of various types for both construction and incident management purposes. The DR46™ is an energy absorbing barrier to shield motorcyclists from impacting guardrail posts which is becoming an area of focus for reducing the amount and severity of injuries.

Road Marking and Road Safety Equipment – The Company also offers preformed tape and a line of road safety accessory products. The preformed tape is used primarily in temporary applications such as markings for work zones, street crossings, and road center lines or boundaries. The road safety equipment consists of mostly plastic and rubber products used for delineation, slowing traffic, and signaling. The Company also manages an ISO 17025 certified testing laboratory, Safe Technologies, Inc., that performs full-scale impact testing of highway safety products in accordance with the National Cooperative Highway Research Program (“NCHRP”) Report 350, the Manual for Assessing Safety Hardware (“MASH”), and the European Norms (EN1317) for these types of products. The NCHRP Report 350 and MASH guidelines are procedures required by the U.S. Department of Transportation Federal Highway Administration for the safety performance evaluation of highway features. The EN1317 Norms are being used to qualify roadway safety products for the European markets.

Other Products – The Company’s Diversified Manufacturing and Tubing business unit manufactures and markets large diameter steel tubing and railroad signals and structures, and provides outsourced manufacturing and production services for other companies. The Company continues to develop new relationships for infrastructure manufacturing in industries outside of agriculture and irrigation. The Company’s customer base includes certain large industrial companies and railroads. Each customer benefits from the Company’s design and engineering capabilities as well as the Company’s ability to provide a wide spectrum of manufacturing services, including welding, machining, painting, forming, galvanizing and assembling hydraulic, electrical, and mechanical components.

Markets – The Company’s primary infrastructure market includes moveable concrete barriers, delineation systems, guardrails and similar protective equipment. The U.S. roadway infrastructure market includes projects such as new roadway construction, bridges, tunnels, maintenance and resurfacing, the purchase of rights-of-way for roadway expansion and development of technologies for relief of roadway congestion. Much of the U.S. highway infrastructure market is driven by government (state and federal) spending programs. For example, the U.S. government funds highway and road improvements through the Federal Highway Trust Fund Program. This program provides funding to improve the nation’s roadway system. Matching funding from the various states may be required as a condition of federal funding. In the long term, the Company believes that the federal program provides a solid platform for growth in the U.S. market, as it is generally acknowledged that additional funding will be required for infrastructure development and maintenance in the future.

6

The European market is presently very different from country to country, but the standardization in performance requirements and acceptance criteria for highway safety devices adopted by the European Committee for Standardization is expected to lead to greater uniformity and a larger installation program. This will also be influenced by the European Union’s prevention program which has the goal to lower highway traffic fatalities.

Competition – The Company competes in certain product lines with several manufacturers, some of whom may have greater financial resources than the Company. The Company competes by continuously improving its products through ongoing research and development activities. The Company’s engineering and research expenses related to infrastructure products totaled approximately $3.5 million, $4.3 million and $3.7 for fiscal years 2012, 2011 and 2010, respectively. The Company competes with certain products and companies in its crash cushion business, but has limited competition in its moveable barrier line, as there is not another moveable barrier product today comparable to the QMB^® system. However, the Company’s barrier product does compete with traditional “safety shaped” concrete barriers and other safety barriers.

Distribution methods and channels – The Company has production and sales operations in Nebraska, California and Italy. Sales efforts consist of both direct sales and sales programs managed by its network of distributors and third-party representatives. The sales teams have responsibility for new business development and assisting distributors and dealers in soliciting large projects and new customers. The distributor and dealer networks have exclusive territories and are responsible for developing sales and providing service, including product maintenance, repair and installation. The typical dealer sells an array of safety supplies, road signs, crash cushions, delineation equipment and other highway products. Customers include Departments of Transportation, municipal transportation road agencies, roadway contractors, subcontractors, distributors and dealers. Due to the project nature of the roadway construction and congestion management markets, the Company’s customer base changes from year-to-year. Due to the limited life of projects, it is rare that a single customer will account for a significant amount of revenues in consecutive years. The customer base also varies depending on the type of product sold. The Company’s moveable barrier products are typically sold to transportation agencies or the contractors or suppliers serving those agencies. In contrast, distributors account for a majority of crash cushion sales since those products have lower price points and tend to have shorter lead times.

GENERAL

Certain information generally applicable to both of the Company’s reportable segments is set forth below.

The following table describes the Company’s total irrigation and infrastructure revenues for the past three years. United States export revenue is included in International as the region of destination. No individual foreign country’s operating revenues were material for separate disclosure purposes.

Total Revenues	$	551.3		100	$	478.9		100	$	358.4		100

SEASONALITY

Irrigation equipment sales are seasonal by nature. Farmers generally order systems to be delivered and installed before the growing season. Shipments to customers located in Northern Hemisphere countries usually peak during the Company’s second and third fiscal quarters for the spring planting period. Sales of infrastructure products are traditionally higher during prime construction seasons and lower in the winter. The primary construction season for Northern Hemisphere countries is from March until late September which corresponds to the Company’s third and fourth fiscal quarters.

CUSTOMERS

The Company is not dependent for a material part of either segment’s business upon a single customer or upon a limited number of customers. The loss of any one customer would not have a material adverse effect on the Company’s financial condition, results of operations or cash flow.

7

ORDER BACKLOG

As of August 31, 2012, the Company has an order backlog of $57.1 million compared with $46.0 million at August 31, 2011. 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.

Generally, the Company manufactures or purchases the components for its irrigation equipment from a sales forecast and prepares the equipment for shipment upon the receipt of a U.S. or international dealer’s firm order. Irrigation equipment orders from U.S. dealers are generally accompanied with a down payment unless they are purchased through one of the Company’s dealer network preferred vendor financing programs. Irrigation equipment orders being delivered to international markets from the U.S. are generally shipped against prepayments or receipt of an irrevocable letter of credit confirmed by a U.S. bank or other secured means, which call for delivery within time periods negotiated with the customer. Orders delivered from the Company’s international irrigation manufacturing operations are generally shipped according to payment and/or credit terms customary to that country or region.

Generally, the Company manufactures or purchases the components for its infrastructure equipment, excluding QMB^® systems, from a sales forecast and prepares the equipment for shipment upon the receipt of a U.S. or international distributor’s firm order. The Company manufactures or purchases the components for its QMB^® systems once a contract has been signed. Generally, QMB^® system contracts require a down payment before manufacturing of the QMB^® system will begin.

RAW MATERIALS AND COMPONENTS

Raw materials used by the Company include coil steel, angle steel, plate steel, zinc, tires, gearboxes, concrete, rebar, fasteners, and electrical and hydraulic components (motors, switches, cable, valves, hose and stators). The Company has, on occasion, faced shortages of certain such materials. The Company believes it currently has ready access to adequate supplies of raw materials and components.

CAPITAL EXPENDITURES

Capital expenditures for fiscal 2012, 2011, and 2010 were $9.9 million, $8.4 million and $5.8 million, respectively. Capital expenditures for fiscal 2013, excluding possible expansion of the leased barrier and barrier-transfer machine fleet, are estimated to be approximately $15.0 to $20.0 million. The planned expenditures include equipment for manufacturing equipment replacement, tooling, and facilities for identified efficiency and capacity improvements. The Company’s management does maintain flexibility to modify the amount and timing of some of the planned expenditures in response to economic conditions.

PATENTS, TRADEMARKS, AND LICENSES

Lindsay’s Zimmatic^®, Greenfield^®, GrowSmart^®, Perrot™, Quickchange^® Moveable Barrier™, ABSORB 350^®, FieldNET^®, TAU^®, Universal TAU-II^®, TAU-II-R™, TAU-B_NR™, X-Tension™, CableGuard™, TESI™, SAB™, ArmourGuard™, PaveGuard™, DR46™, U-MAD™, and other trademarks are registered or applied for in the major markets in which the Company sells its products. Lindsay follows a policy of applying for patents on all significant patentable inventions in markets deemed appropriate. Although the Company believes it is important to follow a patent protection policy, Lindsay’s business is not dependent, to any material extent, on any single patent or group of patents.

EMPLOYEES

The number of persons employed by the Company and its wholly-owned subsidiaries at fiscal year ends 2012, 2011, and 2010 were 1,082, 999 and 891, respectively. None of the Company’s U.S. employees are represented by a union. Certain of the Company’s non-U.S. employees are unionized due to local governmental regulations.

8

ENVIRONMENTAL AND HEALTH AND SAFETY MATTERS

Like other manufacturing concerns, the Company is subject to numerous laws and regulations that govern environmental and occupational health and safety matters. The Company believes that its operations are substantially in compliance with all such applicable laws and regulations and that it holds all necessary permits in each jurisdiction in which its facilities are located. Environmental and health and safety regulations are subject to change and interpretation. In some cases, compliance with applicable regulations or standards may require the Company to make additional capital and operational expenditures. The Company, however, is not currently aware of any material capital expenditures required to comply with such regulations, other than as described in Note L, Commitments and Contingencies, and does not believe that these matters, individually or in the aggregate, are likely to have a material adverse effect on the Company’s consolidated financial condition.

FINANCIAL INFORMATION ABOUT FOREIGN AND U.S. OPERATIONS

The Company’s primary production facilities are located in the United States. The Company has smaller production and sales operations in France, Brazil, Italy and China as well as distribution and sales operations in South Africa, Australia and New Zealand. Most of the Company’s financial transactions are in U.S. dollars, although some export sales and sales from the Company’s foreign subsidiaries, are conducted in local currencies. Approximately 19 percent of total consolidated Company sales were conducted in local currencies in each of fiscal 2012 and 2011.

A portion of the Company’s cash flow is derived from sales and purchases denominated in currencies other than the designated functional currency. To reduce the uncertainty of foreign currency exchange rate movements on these sales and purchase commitments, the Company monitors its risk of foreign currency fluctuations and, at times, may enter into forward exchange or option contracts for transactions denominated in a currency other than the functional currency for certain of the Company’s operations.

In addition to the transactional foreign currency exposures mentioned above, the Company also has translation exposure resulting from translating the financial statements of its international subsidiaries into U.S. dollars. In order to reduce this translation exposure, the Company, at times, utilizes foreign currency forward contracts to hedge its net investment exposure in its foreign operations. For information on the Company’s foreign currency risks, see Item 7A of Part II of this report.

ITEM 1A — Risk Factors

The following are certain of the more significant risks that may affect the Company’s business, financial condition and results of operations.

The Company’s U.S. and international irrigation equipment sales are highly dependent on the agricultural industry and weather conditions. The Company’s U.S. and international irrigation equipment sales are highly dependent upon the need for irrigated agricultural crop production which, in turn, depends upon many factors, including total worldwide crop production, the profitability of agricultural crop production, agricultural commodity prices, net cash farm income, availability of financing for farmers, governmental policies regarding the agricultural sector, water and energy conservation policies, the regularity of rainfall, regional climate change, and foreign currency exchange rates. As farm income decreases, farmers may postpone capital expenditures or seek less expensive irrigation alternatives.

Weather conditions, particularly during the planting and early growing season, can significantly affect the purchasing decisions of purchasers of irrigation equipment. Natural calamities such as regional floods, hurricanes or other storms, and droughts can have significant effects on seasonal irrigation demand. Drought conditions, which generally impact irrigation equipment demand positively over the long term, can adversely affect demand if water sources become unavailable or if governments impose water restriction policies to reduce overall water availability.

The Company’s infrastructure revenues are highly dependent on government funding of transportation projects. The demand for the Company’s infrastructure products depends to a large degree on the amount of government spending authorized to improve road and highway systems. For example, the U.S. government funds highway and road improvements through the Federal Highway Trust Fund Program and matching funding from states may be required as a condition of federal funding. If highway funding is reduced or delayed, it may reduce demand for the Company’s infrastructure products.

The Company’s profitability may be negatively affected by increases in the cost of raw materials, as well as in the cost of energy. Certain of the Company’s input costs, such as the cost of steel, zinc, and other raw materials, may increase rapidly from time to time. Because there is a level of price competition in the market for irrigation equipment and certain infrastructure products, the Company may not be able to recoup increases in these costs through price increases for its products, which would result in reduced profitability. Whether increased operating costs can be passed through to the customer depends on a number of factors, including farm income and the price of competing products. The cost of raw materials can be volatile and is dependent on a number of factors, including availability, demand, and freight costs.

The Company’s profitability may be negatively affected by the disruption or termination of the supply of parts, materials, and components from third-party suppliers. The Company uses a limited number of suppliers for certain parts, materials, and components in the manufacturing process. Disruptions in supply or significant price increases from these suppliers could affect the Company’s operations and profitability. Such disruptions, terminations or cost increases could result in cost inefficiencies, delayed sales or reduced sales.

The Company’s international equipment sales are highly dependent on foreign market conditions and are subject to additional risk and restrictions. For the fiscal year ended August 31, 2012, approximately 36 percent of the Company’s consolidated revenues were generated from international sales and United States export revenue to international regions. Specifically, international revenues are primarily generated from Australia, New Zealand, Canada, Central and Western Europe, Mexico, the Middle East, South Africa, China, and Central and South America. In addition to risks relating to general economic and political stability in these countries, the Company’s international sales are affected by international trade barriers, including governmental policies on tariffs, taxes, import or export licensing requirements, trade sanctions, and foreign currency exchange rates and are generally governed by local laws which can affect the Company’s ability to resolve disputes on contract performance and collectability. International sales are also more susceptible to disruption from changing social economic conditions as well as terrorism, political hostilities, war and similar incidents.

Compliance with applicable environmental and health and safety regulations or standards may require additional capital and operational expenditures. Like other manufacturing concerns, the Company is subject to numerous laws and regulations which govern environmental and occupational health and safety matters. The Company believes that its operations are substantially in compliance with all such applicable laws and regulations and that it holds all necessary permits in each jurisdiction in which its facilities are located. Environmental and health and safety regulations are subject to change and interpretation. Compliance with applicable regulations or standards may require the Company to make additional capital and operational expenditures.

The Company’s Lindsay, Nebraska site was added to the EPA’s list of priority superfund sites in 1989. The Company and its environmental consultants have developed a remedial action work plan, under which the Company continues to work with the EPA to define and implement steps to better contain and remediate the remaining contamination.

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 August 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 Company’s ongoing remediation activities at its Lindsay, Nebraska facility are described in Note L to the Company’s consolidated financial statements.

The Company’s sales and access to credit may be negatively affected by current economic conditions. The ongoing instability in U.S. and international financial and credit markets along with the resulting global recessionary concerns and the slow economic recovery could adversely affect the ability of farmers and government agencies to buy and finance irrigation equipment and highway infrastructure equipment, respectively. Disruptions in the financial and credit markets could also restrict the Company’s ability to access credit financing under its existing credit facilities or to obtain additional financing.

The Company’s consolidated financial results are reported in U.S. dollars while certain assets and other reported items are denominated in the currencies of other countries, creating currency translation risk. The reporting currency for the Company’s consolidated financial statements is the U.S. dollar. Certain of the Company’s assets, liabilities, expenses and revenues are denominated in other countries’ currencies. Those assets, liabilities, expenses and revenues are translated into U.S. dollars at the applicable exchange rates to prepare the Company’s consolidated financial statements. Therefore, increases or decreases in exchange rates between the U.S. dollar and those other currencies affect the value of those items as reflected in the Company’s consolidated financial statements. Substantial fluctuations in the value of the U.S. dollar compared to those other currencies could have a significant impact on the Company’s results.

Expansion of the Company’s business may result in unanticipated adverse consequences. The Company routinely considers possible expansions of the business, both domestically and in foreign locations. Acquisitions, partnerships, joint ventures or other similar major investments require significant managerial resources, which may be diverted from the Company’s other business activities. The risks of any expansion of the business through investments, acquisitions, partnerships or joint ventures are increased due to the significant capital and other resources that the Company may have to commit to any such expansion, which may not be recoverable if the expansion initiative to which they were devoted is not fully implemented or is ultimately unsuccessful. As a result of these risks and other factors, including general economic risk, the Company may not be able to realize projected returns from any recent or future acquisitions, partnerships, joint ventures or other investments.

Overview

The Company manufactures and markets Zimmatic^®, Greenfield^® and Perrot™ center pivot, lateral move, and hose reel irrigation systems. The Company also produces and markets irrigation controls, chemical injection systems and remote monitoring and control systems which it sells under its GrowSmart^® brand. These products are used by farmers to increase or stabilize crop production while conserving water, energy, and labor. Through its acquisitions, the Company has been able to enhance its capabilities in providing innovative, turn-key solutions to customers through the integration of its proprietary pump stations, controls and designs. The Company sells its irrigation products primarily to a world-wide independent dealer network, who resell to their customer, the farmer. The Company’s primary production facilities are located in the United States. The Company has smaller production and sales operations in France, Brazil, Italy and China as well as distribution and sales operations in South Africa, Australia and New Zealand. The Company also manufactures and markets various infrastructure products, including moveable barriers for traffic lane management, crash cushions, preformed reflective pavement tapes and other road safety devices, through its production facilities in Omaha, Nebraska, Rio Vista, California and Milan, Italy. In addition, the Company’s infrastructure segment produces large diameter steel tubing and railroad signals and structures, and provides outsourced manufacturing and production services for other companies.

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. Key factors which impact demand for the Company’s irrigation products include agricultural commodity prices, net cash farm income, crop yields, weather, environmental regulations, availability of financing and interest rates. A key factor which impacts demand for the Company’s infrastructure products is the amount of spending authorized by governments to improve road and highway systems. Much of the U.S. highway infrastructure market is driven by government spending programs. For example, the U.S. government funds highway and road improvements through the Federal Highway Trust Fund Program. This program provides funding to improve the nation’s roadway system. Matching funding from the various states may be required as a condition of federal funding.

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 by global market expansion, improvements in margins, and strategic acquisitions. Since 2001, the Company has added the operations in Europe, South America, South Africa, Australia, New Zealand and China. The addition of those operations has allowed the Company to strengthen its market position in those regions, yet they remain relatively small in scale. As a result, none of the international operations has achieved the operating margin of the United States based irrigation operations.

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 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 does not expect the adoption of this standard to impact the consolidated financial statements except for the requirement of additional disclosures.

16

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 consolidated financial statements.

In December 2011, the FASB issued ASU No. 2011-11, Amendments to Disclosures about Offsetting Assets and Liabilities. The objective of ASU No. 2011-11 is to provide enhanced disclosures that will enable users of its financial statements to evaluate the effect or potential effect of netting arrangements on an entity’s financial position. This includes the effect or potential effect of rights of setoff associated with an entity’s recognized assets and recognized liabilities which include: derivatives, sale and repurchase agreements, reverse sale and repurchase agreements, securities borrowing, and securities lending arrangements. The amendments require enhanced disclosures by requiring improved information about offsetting financial instruments and derivative instruments. The guidance is effective for fiscal years beginning on or after January 1, 2013. The Company does not expect the adoption of this standard to impact its consolidated financial statements.

In July 2012, the FASB issued ASU No. 2012-02, Amendments to Testing Indefinite-Lived Intangible Assets for Impairment. ASU No. 2012-02 allows entities to first assess qualitative factors to determine whether the existence of events and circumstances indicates that it is more likely than not that the indefinite-lived intangible asset is impaired. If, after assessing the totality of events and circumstances, an entity concludes that it is not more likely than not that the indefinite-lived intangible asset is impaired, then the entity is not required to take further action. However, if an entity concludes otherwise, then it is required to determine the fair value of the indefinite-lived intangible asset and perform the quantitative impairment test by comparing the fair value with the carrying amount. An entity also has the option to bypass the qualitative assessment for any indefinite-lived intangible asset in any period and proceed directly to performing the quantitative impairment test. An entity will be able to resume performing the qualitative assessment in any subsequent period. The guidance is effective for fiscal years beginning after September 15, 2012. The Company does not expect the adoption of this standard to impact its consolidated financial statements.

Critical Accounting Policies and Estimates

In preparing the consolidated financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”), management must make a variety of decisions which impact the reported amounts and the related disclosures. Such decisions include the selection of the appropriate accounting principles to be applied and the assumptions on which to base accounting estimates. In reaching such decisions, management applies judgment based on its understanding and analysis of the relevant facts and circumstances. Certain of the Company’s accounting policies are critical, as these policies are most important to the presentation of the Company’s consolidated results of operations and financial condition. They require the greatest use of judgments and estimates by management based on the Company’s historical experience and management’s knowledge and understanding of current facts and circumstances. Management periodically re-evaluates and adjusts the estimates that are used as circumstances change.

Following are the accounting policies management considers critical to the Company’s consolidated results of operations and financial condition:

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 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. At all locations, the Company reserves for obsolete, slow moving, and excess inventory by estimating the net realizable value based on the potential future use of such inventory.

17

Valuation of Goodwill, Identifiable Intangible Assets and Other Long-Lived Assets

Assessment of the potential impairment of goodwill, intangible assets and other long-lived assets is an integral part of the Company’s normal ongoing review of operations. Testing for potential impairment of these assets is significantly dependent on numerous assumptions and reflects management’s best estimates at a particular point in time. The dynamic economic environments in which the Company’s businesses operate and key economic and business assumptions related to projected selling prices, market growth, inflation rates and operating expense ratios, can significantly affect the outcome of impairment tests. Estimates based on these assumptions may differ significantly from actual results. Changes in factors and assumptions used in assessing potential impairments can have a significant impact on the existence and magnitude of impairments, as well as the time in which such impairments are recognized.

Goodwill represents the excess of the purchase price over the fair value of net assets acquired in a business combination. Acquired intangible assets are recognized separately from goodwill. Goodwill and intangible assets with indefinite useful lives are tested for impairment at least annually at August 31 and whenever triggering events or changes in circumstances indicate its carrying value may not be recoverable. The Company performs the impairment analysis at the reporting unit level using a two-step impairment test. Fair value is typically estimated using a discounted cash flow analysis, which requires the Company to estimate the future cash flows anticipated to be generated by the particular assets being tested for impairment as well as to select a discount rate to measure the present value of the anticipated cash flows. When determining future cash flow estimates, the Company considers historical results adjusted to reflect current and anticipated operating conditions. Estimating future cash flows requires significant judgment and assumptions by management in such areas as future economic conditions, industry-specific conditions, product pricing, and necessary capital expenditures. To the extent that the reporting unit is unable to achieve these assumptions, impairment losses may emerge. The Company updated its impairment evaluation of goodwill and intangible assets with indefinite useful lives at August 31, 2012.

The estimated fair value of each of the Company’s reporting units exceeded the respective carrying values by more than 10 percent. Accordingly, no impairment losses were indicated as a result of the annual impairment testing for fiscal years 2012, 2011, and 2010. If assumptions on discount rates and future cash flows change as a result of events or circumstances, and the Company believes that the long-term profitability may have declined in value, then the Company may record impairment charges, resulting in lower profits. Sales and profitability of each of the Company’s reporting units may fluctuate from year to year and within a year. In the evaluation of the fair value of reporting units, the Company looks at the long-term prospects for the reporting unit and recognizes that current performance may not be the best indicator of future prospects or value, which requires management judgment.

Indefinite life intangible assets primarily consist of tradenames/trademarks. The fair value of these assets are determined using a “relief from royalty” analysis that determines the fair value of each trademark through use of a discounted cash flow model that incorporates an estimated “royalty rate” the Company would be able to charge a third party for the use of the particular trademark. When determining the future cash flow estimates, the Company must estimate future net sales and a fair market royalty rate for each applicable tradename at an appropriate discount rate to measure the present value of the anticipated cash flows. Estimating future net sales requires significant judgment by management in such areas as future economic conditions, industry-specific conditions, product pricing, and consumer trends.

Revenue Recognition

The Company’s basic criteria necessary for revenue recognition are: 1) evidence of a sales arrangement exists, 2) delivery of goods has occurred, 3) the seller’s price to the buyer is fixed or determinable, and 4) collectability is reasonably assured. The Company recognizes revenue when these criteria have been met and when title and risk of loss transfers to the customer. The Company generally has no post delivery obligations to its independent dealers other than standard warranties. Revenues and gross profits on intercompany sales are eliminated in consolidation.

18

Revenues from the sale of the Company’s irrigation products to its U.S. independent dealers, international locations, and sales by its international locations are recognized based on the delivery terms in the sales contract. If an arrangement involves multiple deliverables, the delivered items are considered separate units of accounting if the items have value on a stand-alone basis and there is objective and reliable evidence of their fair values. Revenues from the arrangement are allocated to the separate units of accounting based on their objectively determined fair value. Revenues for retail sales of irrigation products are recognized when the product or service is delivered to the end-user customers. A small portion of the Company’s revenues relate to subscription revenue of wireless management services and are recognized on a straight-line basis over the contract term.

Revenues from the sale of infrastructure products are usually recognized when the product is delivered to the customer; however, they are dependent on the specific delivery terms in the sales contract. The Company leases certain infrastructure property held for lease to customers such as moveable concrete barriers and QMB^® systems. Revenues for the lease of infrastructure property held for lease are recognized on a straight-line basis over the lease term. If an infrastructure project is completed ahead of schedule and prior to the lease term end date, the Company accelerates the lease term and the timing of recognized revenue once the Company is no longer required to perform under the lease contract.

The costs related to revenues are recognized in the same period in which the specific revenues are recorded. Shipping and handling fees billed to customers are reported in revenue. Shipping and handling costs incurred by the Company are included in cost of sales. Customer rebates, cash discounts and other sales incentives are recorded as a reduction of revenues at the time of the original sale. Estimates used in the recognition of operating revenues and cost of operating revenues include, but are not limited to, estimates for product warranties, product rebates, cash discounts and fair value of separate units of accounting on multiple deliverables.

Environmental Remediation Liabilities

The Company is subject to an array of environmental laws and regulations relating to the protection of the environment. In particular, the Company committed to remediate environmental contamination of the groundwater at and adjacent to its Lindsay, Nebraska facility (the “site”) with the U.S. Environmental Protection Agency (the “EPA”). The Company and its environmental consultants have developed a remedial action work plan, under which the Company continues to work with the EPA to define and implement steps to better contain and remediate the remaining contamination.

Environmental remediation liabilities include costs directly associated with site investigation and clean up, such as materials, external contractor costs and incremental internal costs directly related to the remedy. The Company accrues the anticipated cost of environmental remediation when the obligation is probable and can be reasonably estimated. Estimates used to record environmental remediation liabilities are based on the Company’s best estimate of probable future costs based on site-specific facts and circumstances. Estimates of the cost for the likely remedy are developed using our internal resources or by third-party environmental engineers or other service providers. The Company records the undiscounted environmental remediation liabilities that represent the points in the range of estimates that are most probable or the minimum amount when no amount within the range is a better estimate than any other amount.

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 August 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. During fiscal 2012, 2011 and 2010, the Company accrued incremental costs of $7.2 million, $1.3 million and $0.7 million for additional environmental monitoring and remediation in connection with the ongoing remedial action work plan.

Revenues

In fiscal 2012, the Company experienced significant growth in nearly all irrigation markets. The overall trend for fiscal 2012 included higher demand for irrigation systems stimulated by positive fundamental drivers in the global agricultural economy offset by lower infrastructure demand due to funding issues and project delays. Operating revenues for fiscal 2012 increased by $72.4 million to $551.3 million compared with $478.9 million in fiscal 2011. The increase is attributable to a $105.4 million increase in irrigation equipment revenues offset in part by a $33.0 million decrease in infrastructure segment revenues.

U.S. irrigation equipment revenues of $305.4 million increased $77.8 million or 34 percent compared to fiscal 2011. The increase in U.S. irrigation equipment revenues is primarily due to a 28 percent increase in the number of irrigation systems sold compared to the prior fiscal year. Favorable economic conditions in U.S. agriculture markets continued to drive strong demand for irrigation equipment. Relatively high commodity prices, with corn prices increasing 28 percent and soybean prices increasing 33 percent from the same period last year, continued to support improved irrigation equipment demand. The U.S. Department of Agriculture (USDA) projects that 2012 Net Farm Income will be the highest on record and 65 percent higher than the ten year average, creating positive economic conditions for U.S. farmers. Despite the severity of the 2012 drought, shortfalls in crop production did not necessarily have a detrimental impact on sector-wide Net Farm Income as shortages raise the prices farmers receive for crops sold and crop insurance partially offsets the impact of lower yields.

20

International irrigation revenues of $169.9 million increased $27.6 million or 19 percent from fiscal 2011 revenues of $142.3 million driven by volume increases in the number of irrigation systems sold due to favorable economic conditions in most international regions. Operating revenues increased in nearly all international markets, most significantly in the Middle East, Latin America, China, Canada and Africa. Long-term market drivers of improving diets in a growing world-wide population combined with the water use efficiencies available from mechanized irrigation systems continue to be positive drivers for global irrigation equipment demand.

Infrastructure products segment revenues of $76.0 million decreased by $33.0 million or 30 percent compared to the prior fiscal year. The decrease in infrastructure revenues was driven primarily by fewer QMB^® system sales.

Gross Margin

Gross profit was $148.5 million for fiscal 2012, an increase of $18.7 million compared to fiscal 2011. Gross profit increased primarily due to a $20.0 million increase in volume partially offset by $1.3 million decrease in gross margin. Gross margin was 26.9 percent for fiscal 2012 compared to 27.1 percent for the prior fiscal year. Infrastructure segment gross margins decreased by 7.5 percentage points due to lower revenues of higher-margin QMB^® systems offset by higher pricing within road safety products and contract manufuacturing. Irrigation segment gross margins increased by 1.2 percentage points driven by fixed cost leverage from increased volume.

Operating Expenses

The Company’s operating expenses of $83.0 million for fiscal 2012 increased $9.8 million compared to fiscal 2011 operating expenses of $73.2 million. Of the $9.8 million increase in operating expenses, $5.9 million is attributable to the increase in the Company’s environmental remediation accrual over the same prior year period related to an updated remediation assessment completed in fiscal 2012. The remaining increase in operating expenses was primarily due to personnel related expenses of $3.4 million driven by higher headcount to support growth and international markets, the inclusion of incremental expenses of an acquired business of $1.9 million, and investments in sales and marketing of $0.6 million, offset in part by decreases in research and development expenses of $1.1 million and a reduction in consultant expenses associated with the implementation of a new enterprise resource planning (ERP) system implemented in the prior year of $0.9 million.

Operating margin was 11.9 percent for fiscal 2012 as compared to 11.8 percent for fiscal 2011. Operating expenses were 15.1 percent of sales for fiscal 2012 compared to 15.3 percent of sales for fiscal 2011. Excluding environmental accruals, operating margin was 13.2 percent for fiscal 2012 as compared to 12.1 percent for fiscal 2011 and operating expenses were 13.8 percent of sales for fiscal 2012 compared to 15.0 percent of sales for fiscal 2011, an improvement attributable primarily to leverage from increased sales generated from substantially similar fixed expenses.

Income Taxes

Income tax expense of $21.8 million for fiscal 2012 increased $2.1 million compared to fiscal 2011 income tax expense of $19.7 million. The increase in income tax expense was primarily due to increases in pretax income. The effective income tax rate decreased to 33.5 percent in fiscal 2012 compared to 34.9 percent in fiscal 2011. The effective income tax rate decreased by 1.4 percentage points primarily due to a net reduction of uncertain tax positions compared to the previous year and a benefit resulting from finalizing the 2011 tax return calculations that were less than estimated in the 2011 income tax provision.

Net Earnings

Net earnings for fiscal 2012 were $43.3 million or $3.38 per diluted share compared to $36.8 million, or $2.90 per diluted share for the prior fiscal year. The Company’s operating income increased to $65.5 million in fiscal 2012 compared to $56.6 million during the prior fiscal year primarily due to an increase in revenues partially offset by higher operating expenses.

(1) Includes $15.0 million and $14.1 million of unallocated general and administrative expenses for fiscal 2011 and fiscal 2010, respectively.

(2) Excludes unallocated corporate general and administrative expenses.

Revenues

Operating revenues for fiscal 2011 increased by $120.5 million to $478.9 million compared with $358.4 million in fiscal 2010. The increase is attributable to a $111.3 million increase in irrigation equipment revenues and a $9.2 million increase in infrastructure segment revenues.

U.S. irrigation equipment revenues of $227.6 million increased $74.8 million or 49 percent compared to fiscal 2010. The increase in U.S. irrigation equipment revenues is primarily due to a 51 percent increase in the number of irrigation systems sold compared to the prior fiscal year. Favorable economic conditions in U.S. agriculture markets continued to drive strong demand for irrigation equipment. Relatively high commodity prices, with corn prices increasing 27 percent and soybean prices increasing 11 percent from the same period last year, continued to support improved irrigation equipment demand. The USDA reported 2011 Net Farm Income to be the highest on record and 47 percent higher than 2010, creating positive economic conditions for U.S. farmers.

International irrigation revenues of $142.3 million increased $36.5 million from fiscal 2010 revenues of $105.8 million. Operating revenues increased in nearly all international markets, most significantly in China, Brazil, the Middle East and Australia/New Zealand. Long-term market drivers of improving diets in a growing world-wide population combined with the water use efficiencies available from mechanized irrigation systems continue to be positive drivers for global irrigation equipment demand.

Infrastructure products segment revenues of $109.0 million increased by $9.2 million or 9 percent compared to the prior fiscal year. The increase in infrastructure revenues was driven primarily by higher QMB^® system revenue and from railroad signals and structures, commercial tubing and contract manufacturing businesses.

22

Gross Margin

Gross profit was $129.8 million for fiscal 2011, an increase of $30.9 million compared to fiscal 2010. Gross margin was 27.1 percent for fiscal 2011 compared to 27.6 percent for the prior fiscal year. Gross profit increased primarily due to a $34.0 million increase in the volume of irrigation systems sold driven by positive fundamental drivers in irrigation equipment demand partially offset by a $2.8 million decrease in gross margins due to higher average material costs and inefficiencies associated with the implementation of a new ERP system in fiscal 2011.

Operating Expenses

The Company’s operating expenses of $73.2 million for fiscal 2011 increased $12.1 million compared to fiscal 2010 operating expenses of $61.1 million. The increase in operating expenses for fiscal 2011 was primarily attributable to higher incentive compensation of $2.5 million due to improved operating results, inclusion of operating expenses from acquisitions completed in fiscal 2010 of $2.4 million, higher research and development expenses of $1.3 million and investments in sales and marketing of $0.8 million. Operating expenses were 15.3 percent of sales for fiscal 2011 compared to 17.0 percent of sales for fiscal 2010.

Income Taxes

Income tax expense of $19.7 million for fiscal 2011 increased $7.8 million compared to fiscal 2010 income tax expense of $11.9 million. The increase in income tax expense was primarily due to increases in pretax income. The effective income tax rate increased to 34.9 percent in fiscal 2011 compared to 32.4 percent in fiscal 2010. The increase in the effective income tax rate is primarily due to a reduction in state income tax credits of $1.4 million compared to fiscal 2010.

Net Earnings

Net earnings for fiscal 2011 were $36.8 million or $2.90 per diluted share for fiscal 2011 compared to $24.9 million, or $1.98 per diluted share for the prior fiscal year. The Company’s operating income increased to $56.6 million in fiscal 2011 compared to $37.8 million during the prior fiscal year primarily due to an increase in revenues partially offset by higher operating expenses.

Liquidity and Capital Resources

The Company’s cash and cash equivalents totaled $143.4 million at August 31, 2012 compared with $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 $18.1 million and $10.2 million as of August 31, 2012 and 2011, respectively, and does not expect these investments to have a significant impact on the Company’s overall liquidity. The Company does not intend to repatriate funds; however, the Company would need to accrue and pay taxes if these funds were repatriated.

Net working capital was $218.4 million at August 31, 2012, as compared with $178.4 million at August 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 $52.4 million during the year ended August 31, 2012 compared to $43.1 million provided by operations during the same prior year period. Cash provided by operations increased by $9.4 million compared to the prior year period primarily as a result of increased earnings ($6.5 million) and positive cash flow changes in receivables ($5.1 million) and current taxes payable ($7.7 million) offset in part by decreases due to negative cash flow changes in other current liabilities ($9.8 million).

Cash flows used in investing activities totaled $6.8 million during the year ended August 31, 2012 compared to cash flows used in investing activities of $15.6 million during the same prior year period. 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 as well as the impact of an acquisition of $6.2 million that occurred during the first quarter of fiscal 2011.

23

Capital spending of $9.9 million in fiscal 2012 increased compared to the prior year capital spending of $8.4 million.

Cash flows used in financing activities totaled $8.8 million during the year ended August 31, 2012 compared to cash flows used in financing activities of $3.4 million during the same prior year period. The $5.4 million increase in cash used in financing activities was primarily due to a $4.8 million increase in share-based compensation activities and an increase of $0.6 million of additional dividends paid. The Company’s total interest-bearing debt decreased from $8.6 million at August 31, 2011 to $4.3 million at August 31, 2012 due to four quarterly principal payments. The remaining $4.3 million of interest-bearing debt at August 31, 2012 is scheduled to be paid by June 10, 2013.

Euro Line of Credit

The Company’s wholly-owned European subsidiary, Lindsay Europe SAS, 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 August 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 August 31, 2012 and 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 (1.38 percent at August 31, 2012). Unpaid principal and interest is due by January 31, 2013. The Company intends to renew the Euro Line of Credit upon expiration of its term.

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 Barrier Systems, Inc., a wholly owned subsidiary of the Company (“BSI”). Borrowings under the BSI Term Note bear interest at a rate equal to LIBOR plus 50 basis points (0.65 percent at August 31, 2012). The Company effectively fixed the economic effect of the variable interest rate at 6.05 percent through an interest rate swap as described in Note K, Financial Derivatives, to the 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.

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 August 31, 2012 and 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 (1.28 percent at August 31, 2012), 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 similar 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 August 31, 2012 and 2011, the Company was in compliance with all loan covenants.

Inflation

The Company is subject to the effects of changing prices. During fiscal 2012, the Company realized pricing volatility for purchases of certain commodities, in particular steel and zinc products, used in the production of its products. While the cost outlook for commodities used in the production of the Company’s products is not certain, management believes it can manage these inflationary pressures by introducing appropriate sales price adjustments and by actively pursuing internal cost reduction efforts, while further refining the Company’s inventory and raw materials risk management system. However, competitive market pressures may affect the Company’s ability to pass price adjustments along to its customers.

24

Contractual Obligations, Commercial Commitments and Off-Balance Sheet Arrangements

In the normal course of business, the Company enters into contracts and commitments which obligate the Company to make future payments. The Company uses off-balance sheet arrangements, such as leases accounted for as operating leases, standby letters of credit and performance bonds, where sound business principles warrant their use. The table below sets forth the Company’s significant future obligations by time period.

$ in thousands Contractual Obligations	Total		Less than 1 Year		2-3 Years		4-5 Years		More than 5 Years
Leases	$	8,364	$	2,404	$	2,406	$	1,840	$	1,714
Term Note Obligation		4,285		4,285		—		—		—

Total	$	21,433	$	7,343	$	3,483	$	2,895	$	7,712

⁽¹⁾ Future cash flows for unrecognized tax benefits reflect the recorded liability, including interest and penalties, in accordance with ASC 740 as of August 31, 2012. Amounts for which the year of settlement cannot be reasonably estimated have been included in the “More than 5 Years” column.

The Company does not have any additional off-balance sheet arrangements that have or are reasonably likely to have a material current or future effect on the Company’s financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

Market Conditions and Fiscal 2013 Outlook

Farm incomes and commodity prices remain strong by historical standards and have continued to drive positive farmer sentiment. As of August 28, 2012, the USDA projects U.S. 2012 Net Farm Income to be the highest on record at $122.2 billion and 65 percent higher than the ten year average of $74.0 billion, continuing to represent positive economic conditions for U.S. farmers. Adverse weather conditions in several parts of the world, and most notably the drought in the U.S., has altered the outlook for the overall agriculture sector and particularly irrigation equipment. Current price levels of commodities suggest that 2013 may potentially be a positive year for irrigation equipment demand. The U.S. federal government examines the level of farm subsidies and tax credits from time to time and changes to these programs could have a positive or adverse 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. However, the Company has made progress in reducing the infrastructure segment cost structure in 2012 and expects sales growth and profit improvement in the infrastructure business in 2013. The QMB^® system project delays have not significantly changed the Company’s perspective on the likelihood of future demand for QMB^® systems. The outlook for government funded infrastructure spending remains challenging due to global governmental budget constraints. During 2012 the U.S. government extended the multi-year U.S. highway bill through 2014, creating moderately positive sentiment for U.S. infrastructure spending by setting U.S. transportation policy for the next two years. However, the bill continues the trend of decreasing investment in road transportation and still limits long-term infrastructure projects since it was only extended for two years. 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.

25

As of August 31, 2012, the Company has an order backlog of $57.1 million compared with $46.0 million at August 31, 2011 and $44.5 million at May 31, 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 Company’s 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 by employing sound business strategies, including without limitation global market expansion, improvements in margins, and/or strategic acquisitions.

ITEM 7A – 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 August 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 year ended August 31, 2012, the Company estimates the potential decrease in operating income from a 10 percent 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, intercompany transactions and future settlement of foreign denominated assets and liabilities. The Company had $3.0 million of U.S. dollar equivalent cash flow forward exchange contracts and option contracts outstanding as of August 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 August 31, 2012, the Company had outstanding Euro foreign currency forward contracts to sell 26.5 million Euro at fixed prices expected to settle during the first quarter of fiscal 2013. Based on the net investments contracts outstanding at August 31, 2012, the Company estimates the potential decrease in fair value from a 10 percent adverse change in the underlying exchange rates would be approximately $3.3 million. This decrease in fair value would be reflected as a reduction to other comprehensive income offsetting the translation exposure or adjustment 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.

We have audited the accompanying consolidated balance sheets of Lindsay Corporation and subsidiaries (the Company) as of August 31, 2012 and 2011, and the related consolidated statements of operations, shareholders’ equity and comprehensive income, and cash flows for each of the years in the three-year period ended August 31, 2012. In connection with our audits of the consolidated financial statements, we have also audited the financial statement schedule listed in Item 15(a)(2) of this Form 10-K. These consolidated financial statements and financial statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements and financial statement schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Lindsay Corporation and subsidiaries as of August 31, 2012 and 2011, and the results of their operations and their cash flows for each of the years in the three-year period ended August 31, 2012, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, present fairly, in all material respects, the information set forth therein.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company’s internal control over financial reporting as of August 31, 2012, based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated October 26, 2012 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

A. DESCRIPTION OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

Lindsay Corporation, along with its subsidiaries (collectively called “Lindsay” or the “Company”), is a global leader in providing a variety of proprietary water management and road infrastructure products and services. The Company has been involved in the manufacture and distribution of agricultural equipment since 1955 and has grown from a regional company to an international agribusiness and highway infrastructure firm with worldwide sales and distribution. Lindsay, a Delaware corporation, maintains its corporate offices in Omaha, Nebraska. The Company has operations which are categorized into two major reporting segments.

Irrigation Segment – The Company’s irrigation segment includes the manufacture and marketing of center pivot, lateral move, and hose reel irrigation systems which are used principally in the agricultural industry to increase or stabilize crop production while conserving water, energy, and labor. The irrigation segment also manufactures and markets repair and replacement parts for its irrigation systems and controls, and designs, manufactures and services water pumping stations and controls for the agriculture, golf, landscape and municipal markets. The Company continues to strengthen irrigation product offerings through innovative technology such as GPS positioning and guidance, variable rate irrigation, wireless irrigation management, and smartphone application. The Company’s principal irrigation manufacturing facilities are located in Lindsay, Nebraska and Hartland, Wisconsin. Internationally, the Company has production operations in France, Brazil and China as well as distribution operations in South Africa, Australia and New Zealand. The Company also exports some of its equipment from the U.S. to other international markets.

Infrastructure Segment – The Company’s infrastructure segment includes the manufacture and marketing of moveable barriers, specialty barriers, crash cushions and end terminals, road marking and road safety equipment, large diameter steel tubing, railroad signals and structures, and outsourced manufacturing services. The principal infrastructure manufacturing facilities are located in Rio Vista, California, Milan, Italy, and Omaha, Nebraska.

Notes to the consolidated financial statements describe various elements of the financial statements and the accounting policies, estimates, and assumptions applied by management. While actual results could differ from those estimated at the time of preparation of the consolidated financial statements, management believes that the accounting policies, assumptions, and estimates applied promote the representational faithfulness, verifiability, neutrality, and transparency of the accounting information included in the consolidated financial statements.

The significant accounting policies of the Company are as follows:

(1) Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany balances and transactions are eliminated in consolidation.

(2) Reclassifications

Certain reclassifications have been made to prior financial statements to conform to the current-year presentation.

(3) Stock Based Compensation

The Company recognizes compensation expense for all share-based payment awards made to employees and directors based on estimated fair values on the date of grant. The Company uses the straight-line amortization method over the vesting period of the awards. The Company has historically issued shares upon exercise of stock options or vesting of restricted stock units or performance stock units from new stock issuances, except for certain non-plan option shares granted in March 2000 that are issued from Treasury Stock upon exercise. All outstanding non-plan option shares were exercised in fiscal 2010.

The value of the portion of the award that is ultimately expected to vest is recognized as expense in the Company’s Consolidated Statement of Operations over the periods during which the employee or director is required to perform a service in exchange for the award.

32

The Company uses the Black-Scholes option-pricing model (“Black-Scholes model”) as its valuation method for stock option awards. Under the Black-Scholes model, the fair value of stock option awards on the date of grant is estimated using an option-pricing model that is affected by the Company’s stock price as well as assumptions regarding a number of highly complex and subjective variables. These variables include, but are not limited to the Company’s expected stock price volatility over the term of the awards and actual and projected employee stock option exercise behaviors. Restricted stock, restricted stock units, performance shares and performance stock units issued under the 2010 Long-Term Incentive Plan will have a grant date fair value equal to the fair market value of the underlying stock on the grant date less present value of expected dividends.

(4) Revenue Recognition

The Company’s basic criteria necessary for revenue recognition are: 1) evidence of a sales arrangement exists, 2) delivery of goods has occurred, 3) the seller’s price to the buyer is fixed or determinable, and 4) collectability is reasonably assured. The Company recognizes revenue when these criteria have been met and when title and risk of loss transfers to the customer. The Company generally has no post delivery obligations to its independent dealers other than standard warranties. Revenues and gross profits on intercompany sales are eliminated in consolidation. If an arrangement involves multiple deliverables, the delivered items are considered separate units of accounting if the items have value on a stand-alone basis and there is objective and reliable evidence of their fair values. Revenues from the arrangement are allocated to the separate units of accounting based on their objectively determined fair value.

The costs related to revenues are recognized in the same period in which the specific revenues are recorded. Shipping and handling fees billed to customers are reported in revenue. Shipping and handling costs incurred by the Company are included in cost of sales. Customer rebates, cash discounts and other sales incentives are recorded as a reduction of revenues at the time of the original sale. Estimates used in the recognition of operating revenues and cost of operating revenues include, but are not limited to, estimates for product warranties, product rebates, cash discounts and fair value of separate units of accounting on multiple deliverables.

(5) Receivables and Allowances

Trade receivables are reported on the balance sheet net of any doubtful accounts. Allowances for doubtful accounts are maintained in amounts considered to be appropriate in relation to the receivables outstanding based on collection experience, economic conditions and credit risk quality.

(6) Warranty Costs

The Company’s provision for product warranty reflects management’s best estimate of probable liability under its product warranties. At the time a sale is recognized, the company records the estimated future warranty costs. The Company generally determines its total future warranty liability by applying historical claims rate experience to the amount of equipment that has been sold and is still within the warranty period. In addition, the Company records provisions for known warranty claims. This provision is periodically adjusted to reflect actual experience.

(7) Cash and Cash Equivalents

Cash equivalents consist of investments with original maturities of three months or less.

(8) 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 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. At all locations, the Company reserves for obsolete, slow moving, and excess inventory by estimating the net realizable value based on the potential future use of such inventory.

33

(9) Property, Plant and Equipment

Property, plant, equipment, and capitalized assets held for lease are stated at cost. The Company capitalizes major expenditures and charges to operating expenses the cost of current maintenance and repairs. Provisions for depreciation and amortization have been computed principally on the straight-line method for buildings and equipment. Rates used for depreciation are based principally on the following expected lives: buildings -- 15 to 30 years; temporary structures — 5 years; equipment -- 3 to 10 years; leased Barrier Transfer Machines — 8 to 10 years; leased barriers — 12 years; other -- 2 to 20 years and leasehold improvements – shorter of the economic life or term of the lease. All of the Company’s long-lived asset groups are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the sum of the expected future cash flows is less than the carrying amount of the asset group, an impairment loss is recognized based upon the difference between the fair value of the asset and its carrying value. During fiscal 2012, 2011 and 2010 no impairment losses were recognized. The cost and accumulated depreciation relating to assets retired or otherwise disposed of are eliminated from the respective accounts at the time of disposition. The resulting gain or loss is included in operating income in the consolidated statements of operations.

(10) Goodwill and Intangible Assets

Goodwill represents the excess of the purchase price over the fair value of net assets acquired in a business combination. Acquired intangible assets are recognized separately from goodwill. Goodwill and intangible assets with indefinite useful lives are tested for impairment at least annually at August 31 and whenever triggering events or changes in circumstances indicate its carrying value may not be recoverable. The Company performs the impairment analysis at the reporting unit level using a two-step impairment test. Fair value is typically estimated using a discounted cash flow analysis, which requires the Company to estimate the future cash flows anticipated to be generated by the particular assets being tested for impairment as well as a discount rate to measure the present value of the anticipated cash flows. When determining future cash flow estimates, the Company considers historical results adjusted to reflect current and anticipated operating conditions. Estimating future cash flows requires significant judgment and assumptions by management in such areas as future economic conditions, industry-specific conditions, product pricing, and necessary capital expenditures. To the extent that the reporting unit is unable to achieve these assumptions, impairment losses may emerge.

(11) Income Taxes

Income taxes are accounted for utilizing the asset and liability method of accounting for income taxes. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying value of existing assets and liabilities and their respective tax bases. These expected future tax consequences are measured based on currently enacted tax rates. The effect of tax rate changes on deferred tax assets and liabilities is recognized in income during the period that includes the enactment date.

When the Company has claimed tax benefits that may be challenged by a tax authority, the Company recognizes tax benefits only for tax positions that are more likely than not to be sustained upon examination by tax authorities. The amount recognized is measured as the largest amount of benefit that is greater than 50 percent likely to be realized upon settlement. A liability for “unrecognized tax benefits” is recorded for any tax benefits claimed in the Company’s tax returns that do not meet these recognition and measurement standards.

(12) 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. Under the treasury stock method, the amount the employee must pay for exercising stock options, the amount of compensation cost for future service that the Company has not yet recognized, and the amount of excess tax benefits that would be recorded in additional paid-in-capital when exercised are assumed to be used to repurchase shares.

34

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

	For the years ended August 31,
	2012		2011		2010
Restricted stock units		3,241		2,062		476
Stock options		29,181		—		—

Performance stock units are excluded from the calculation of dilutive potential common shares until the threshold performance conditions have been satisfied. At August 31, 2012 and 2010, the threshold performance conditions for certain performance stock units had been satisfied resulting in the inclusion of 37,746 and 13,395, respectively, of performance stock units in the calculation of diluted net earnings per share. At August 31, 2011, the threshold performance conditions for certain performance stock units had not been satisfied. At August 31, 2012, 2011 and 2010, there were 43,388, 98,625 and 70,693, respectively, of performance stock units excluded from the calculation of diluted net earnings per share because the threshold performance conditions had not been satisfied.

(13) Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

(14) Derivative Instruments and Hedging Activities

The Company uses certain financial derivatives to mitigate its exposure to volatility in interest rates and foreign currency exchange rates. All derivative instruments are recorded on the balance sheet at their respective fair values. The Company uses these derivative instruments only to hedge exposures in the ordinary course of business and does not invest in derivative instruments for speculative purposes. On the date a derivative contract is entered into, the Company may elect to designate the derivative as a fair value hedge, a cash flow hedge, or the hedge of a net investment in a foreign operation.

The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivative that is used in the hedging transaction is highly effective. For those 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 earnings. All changes in derivative fair values due to ineffectiveness are recognized currently in income.

The Company discontinues hedge accounting prospectively when it is determined that the derivative is no longer effective in offsetting changes in the cash flows of the hedged item, the derivative expires or is sold, terminated, or exercised, or management determines that designation of the derivative as a hedging instrument is no longer appropriate. In situations in which the Company does not elect hedge accounting or hedge accounting is discontinued and the derivative is retained, the Company carries or continues to carry the derivative at its fair value on the balance sheet and recognizes any subsequent changes in its fair value through 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 August 31, 2012, the Company’s derivative counterparty had investment grade credit ratings.

35

(15) Fair Value Measurements

The Company’s disclosure of the fair value of assets and liabilities is based on a three-level hierarchy for fair value measurements based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. Inputs refers broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk. The categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Financial assets and liabilities carried at fair value will be classified and disclosed in one of the following three categories:

• Level 1 – inputs to the valuation techniques are quoted prices in active markets for identical assets or liabilities

• Level 2 – inputs to the valuation techniques are other than quoted prices but are observable for the assets or liabilities, either directly or indirectly

• Level 3 – inputs to the valuation techniques are unobservable for the assets or liabilities

The following table presents the Company’s financial assets and liabilities measured at fair value based upon the level within the fair value hierarchy in which the fair value measurements fall, as of August 31, 2012 and 2011, respectively:

The carrying amount of long-term debt (including current portion) was $4.3 million and $8.6 million as of August 31, 2012 and 2011, respectively. The fair value of this debt at August 31, 2012 and 2011, was estimated at $4.3 million and $8.5 million, 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. Goodwill is tested for impairment annually or whenever there is an impairment indicator. All goodwill is assigned to a reporting unit, where it is subject to an impairment test based on fair value using Level 3 input as defined in the fair value hierarchy.

(16) Treasury Stock

When the Company repurchases its outstanding stock, it records the repurchased shares at cost as a reduction to shareholders’ equity. The weighted average cost method is utilized for share re-issuances. The difference between the cost and the re-issuance price is charged or credited to a “capital in excess of stated value – treasury stock” account to the extent that there is a sufficient balance to absorb the charge. If the treasury stock is sold for an amount less than its cost and there is not a sufficient balance in the capital in excess of stated value – treasury stock account, the excess is charged to retained earnings.

(17) Contingencies

The Company’s accounting for contingencies covers a variety of business activities including contingencies for legal exposures and environmental exposures. The Company accrues these contingencies when its assessments indicate that it is probable that a liability has been incurred and an amount can be reasonably estimated. The Company’s estimates are based on currently available facts and its estimates of the ultimate outcome or resolution. Actual results may differ from the Company’s estimates resulting in an impact, positive or negative, on earnings.

(18) Translation of Foreign Currency

The Company’s portion of the assets and liabilities related to foreign investments are translated into U.S. dollars at the exchange rates in effect at the balance sheet date. Revenue and expenses are translated at the average rates of exchange prevailing during the year. Unrealized gains or losses are reflected within common shareholders’ equity as accumulated other comprehensive income or loss.

B. ACQUISITIONS

The Company acquires businesses synergistic to the Company’s core irrigation and infrastructure businesses and to align with its strategic intent with respect to growth markets and adjacent product lines or technologies. The Company accounts for business combinations in accordance with ASC 805 – Business Combinations, which requires the recognition of the identifiable assets acquired, liabilities assumed, goodwill, and any noncontrolling interest in the acquiree. In addition, the Company expenses all acquisition-related costs in the period in which the costs are incurred and the services received.

IRZ Consulting, LLC

On August 26, 2011, the Company completed the acquisition of certain assets of IRZ Consulting, LLC (“IRZ”) based in Pasco, Washington and Portland, Oregon. The IRZ business is involved in irrigation engineering, field monitoring, and broadband internet services for rural areas. Total consideration paid was $4.9 million which was financed with cash on hand. The fair value assigned to the assets was finalized in the first quarter of the Company’s 2012 fiscal year. Goodwill recorded in connection with this acquisition is deductible for income tax purposes.

WMC Technology Limited

On November 3, 2010, the Company completed the acquisition of certain assets of WMC Technology Limited (“WMC”) based in Feilding, New Zealand. The assets acquired primarily relate to technology that has enhanced the Company’s irrigation product offerings. Total consideration paid was $1.3 million which was financed with cash on hand. The fair value assigned to the assets was finalized in the second quarter of the Company’s 2011 fiscal year. Goodwill recorded in connection with this acquisition is not deductible for income tax purposes.

The total purchase price for IRZ and WMC has been allocated to the tangible and intangible assets acquired and liabilities assumed based on fair value assessments. The Company’s allocation of purchase price for these acquisitions consisted of current assets of $0.9 million, fixed assets of $0.6 million, finite-lived intangible assets of $1.6 million, indefinite-lived intangible assets of $1.0 million, goodwill of $2.2 million, other long-term assets of $1.1 million, current liabilities of $0.4 million, and long-term liabilities of $0.8 million. Goodwill resulting from business combinations is largely attributable to the existing workforce and historical and projected profitability of the acquired businesses. The goodwill associated with WMC and IRZ are included in the goodwill of the Company’s irrigation segment. Pro forma information related to acquisitions was not included because the impact on the Company’s consolidated financial statements was not considered to be material.

Digitec, Inc.

On August 31, 2010, the Company completed the acquisition of all outstanding shares of stock of Digitec, Inc., (“Digitec”) based in Milford, Nebraska. Digitec is an electronics research, development and manufacturing company. The addition of Digitec enhances the Company’s capabilities in providing electronic design and integration. Total consideration paid to the selling shareholders was $6.4 million which was financed with cash on hand. The purchase price has been allocated to the tangible and intangible assets and liabilities assumed based on fair value assessments. The Company’s allocation of purchase price consisted of current assets of $1.1 million (including $0.1 million of cash), fixed assets of $0.8 million, intangible assets of $1.5 million, goodwill of $4.4 million, current liabilities of $0.5 million and long-term liabilities of $0.9 million. Goodwill related to the acquisition of Digitec primarily relates to intangible assets that do not qualify for separate recognition, including the experience and knowledge of Digitec management, its assembled workforce, and its intellectual capital and specialization within the Irrigation industry. Goodwill recorded in connection with this acquisition is non-deductible for income tax purposes. Proforma data is not presented for this acquisition, as it was not considered material.

Total income tax provision resulted in effective tax rates differing from that of the statutory United States Federal income tax rates. The reasons for these differences are:

In fiscal 2010, the Company recognized investment tax credits from the state of Nebraska’s economic development program, the Nebraska Advantage Act. These credits, which expire in fiscal 2018, reduced income tax expense by $1.4 million.

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company’s deferred tax assets and liabilities are as follows:

	August 31,
$ in thousands	2012			2011
Deferred tax assets:
Deferred rental revenue	$	382		$	1,233
Employee benefits liability		1,282			1,305

Deferred tax liabilities:
Intangible assets		(6,195	)		(7,088	)
Property, plant and equipment		(8,210	)		(9,054	)
Inventory		(115	)		(113	)

Total deferred tax liabilities		(14,816	)		(17,313	)
Net deferred tax liabilities	$	171		$	(3,683	)

In assessing the ability to realize deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. Based upon the level of historical taxable income and projections for future taxable income over the periods in which the deferred tax assets are deductible, management believes it is more likely than not that the Company will realize the benefits of these deductible differences. Accordingly, a valuation allowance for deferred tax assets at August 31, 2012 and 2011 has not been established.

The determination of the unrecognized deferred tax liability for permanently reinvested foreign earnings is not practical as the Company does not intend to repatriate earnings of its non-U.S. subsidiaries and accordingly, has not provided a U.S. deferred income tax liability for cumulative earnings on non-U.S. affiliates and associated companies that have been reinvested indefinitely. The Company continues to analyze the potential tax impact should it elect to repatriate non-U.S. earnings and would recognize a deferred income tax liability if the Company were to determine that such earnings are no longer indefinitely reinvested.

The Company recognizes tax benefits only for tax positions that are more likely than not to be sustained upon examination by tax authorities. The amount recognized is measured as the largest amount of benefit that is greater than 50 percent likely to be realized upon settlement. Unrecognized tax benefits are tax benefits claimed in the Company’s tax returns that do not meet these recognition and measurement standards.

A reconciliation of changes in pre-tax unrecognized tax benefits is as follows:

	August 31,
$ in thousands	2012			2011
Unrecognized Tax Benefits at September 1	$	1,565		$	1,112
Increases for positions taken in current year		2			78
Increases for positions taken in prior years		61			448
Decreases for positions taken in prior years		(44	)		—
Settlements with taxing authorities		(42	)		—
Reduction resulting from lapse of applicable statute of limitations		(173	)		(87	)
Other increases (decreases)		(60	)		14
Unrecognized Tax Benefits at August 31	$	1,309		$	1,565

The net amount of unrecognized tax benefits at August 31, 2012 and 2011 that, if recognized, would impact the Company’s effective tax rate was $1.3 million and $1.6 million, respectively. Recognition of these tax benefits would have a favorable impact on the Company’s effective tax rate.

The Company recognizes accrued interest and penalties related to unrecognized tax benefits in income tax expense. Total accrued pre-tax liabilities for interest and penalties included in the unrecognized tax benefits liability were $0.5 million and $0.5 million for the years ended August 31, 2012 and 2011, respectively.

The Company files income tax returns in the U.S. federal jurisdiction, and various state and foreign jurisdictions. The Company is no longer subject to examination by tax authorities in most jurisdictions for years prior to 2009.

While it is expected that the amount of unrecognized tax benefits will change in the next twelve months as a result of the expiration of statutes of limitations, the Company does not expect this change to have a significant impact on its results of operations or financial position.

Amortization expense for amortizable intangible assets was $2.9 million, $2.8 million and $2.6 million for 2012, 2011, and 2010, respectively. Amortizable intangible assets are being amortized using the straight-line method over an average term of approximately 11.3 years.

Future estimated amortization of intangible assets for the next five years is as follows:

Fiscal Years	$ in thousands
2013	$	2,803
2014		2,748
2015		2,446
2016		2,128

The Company updated its impairment evaluation of goodwill and intangible assets with indefinite useful lives at August 31, 2012. The estimated fair value of all of the Company’s reporting units each exceeded the respective carrying values by more than 10 percent. Accordingly, no impairment losses were indicated as a result of the annual impairment testing for fiscal years 2012, 2011 and 2010. The Company does not include a roll forward of impairment losses because the Company has never had an impairment loss.

J. CREDIT ARRANGEMENTS

Euro Line of Credit

The Company’s wholly-owned European subsidiary, Lindsay Europe SAS, 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”). There were no borrowings outstanding on this credit agreement at August 31, 2012 or 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, (1.38 percent at August 31, 2012). Unpaid principal and interest is due by January 31, 2013. The Company intends to renew the Euro Line of Credit upon expiration of its term.

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 (0.65 percent at August 31, 2012). The Company effectively fixed the economic effect of the variable interest rate at 6.05 percent through an interest rate swap as described in Note K, Financial Derivatives. 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 in June of 2013.

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 August 31, 2012 and 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 (1.28 percent at August 31, 2012), 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 similar 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 August 31, 2012 and 2011, the Company was in compliance with all loan covenants.

Long-term debt consists of the following:

	August 31,

Interest expense was $0.5 million, $0.8 million and $1.6 million for the years ended August 31, 2012, 2011 and 2010, respectively. All remaining principal payments on the term note are due within one year.

K. FINANCIAL DERIVATIVES

Financial derivatives consist of the following:

	Fair Values of Derivative Instruments

In addition, accumulated other comprehensive income included gains, net of related income tax effects of $2.4 million and $0.5 million at August 31, 2012 and 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 effectively convert or hedge the variable interest rate on the entire amount of this borrowing to achieve a net 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 (see Note J, Credit Arrangements). Changes in the fair value of the interest rate swap designated as the hedging instrument that effectively offset the variability of cash flows associated with the variable-rate, long-term debt obligation 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 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 $3.0 million and $0.0 million of U.S. dollar equivalent cash flow forward exchange contracts and option contracts outstanding as of August 31, 2012 and 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.

44

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.

During fiscal 2012, 2011 and 2010, the Company settled Euro foreign currency forward contracts resulting in after-tax net gains (losses) of $1.8 million, ($0.7 million) and $0.3 million, respectively, which were included in OCI as part of a currency translation adjustment. There were no amounts recorded in the consolidated statement of operations related to ineffectiveness of Euro foreign currency forward contracts for the years ended August 31, 2012, 2011 and 2010. Accumulated currency translation adjustment in AOCI at August 31, 2012, 2011 and 2010 reflected realized and unrealized after-tax gains of $2.4 million, $0.7 million and $1.5 million, respectively.

At August 31, 2012 and 2011, the Company had outstanding Euro foreign currency forward contracts to sell 26.5 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.

L. COMMITMENTS AND CONTINGENCIES

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. No such current proceedings, individually or in the aggregate, are expected to have a material effect on the business or financial condition of the Company.

Environmental Remediation

In 1992, the Company entered into a consent decree with the U.S. Environmental Protection Agency (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 fiscal 2012.

45

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 August 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 August 31, 2012 and 2011:

Environmental Remediation Liabilities
$ in thousands	August 31,		August 31,
Balance Sheet Location	2012		2011
Other current liabilities	$	2,414	$	1,540
Other noncurrent liabilities		5,200		—
Total environmental remediation liabilities	$	7,614	$	1,540

Leases

The Company leases land, buildings, machinery, equipment, and computer equipment under various noncancelable operating lease agreements. At August 31, 2012, future minimum lease payments under noncancelable operating leases were as follows:

Fiscal Years	$ in thousands
2013	$	2,404
2014		1,329
2015		1,077
2016		992

Thereafter		1,714
	$	8,364

Lease expense was $3.6 million, $3.4 million and $2.8 million for the years ended August 31, 2012, 2011, and 2010, respectively.

M. RETIREMENT PLANS

The Company has a defined contribution profit-sharing plan covering substantially all of its full-time U.S. employees. Participants may voluntarily contribute a percentage of compensation, but not in excess of the maximum allowed under the Internal Revenue Code. The plan provides for a matching contribution by the Company. The Company’s total contributions charged to expense under this plan were $0.5 million, $0.5 million and $0.6 million for the years ended August 31, 2012, 2011 and 2010, respectively.

A supplementary non-qualified, non-funded retirement plan for six former executives is also maintained. Plan benefits are based on the executive’s average total compensation during the three highest compensation years of employment. This unfunded supplemental retirement plan is not subject to the minimum funding requirements of ERISA. The Company has purchased life insurance policies on certain former executives named in this supplemental retirement plan to provide funding for this liability.

As of August 31, 2012 and 2011, the funded status of the supplemental retirement plan was recorded in the consolidated balance sheets. The Company utilizes an August 31 measurement date for plan obligations related to the supplemental retirement plan. As this is an unfunded retirement plan, the funded status is equal to the benefit obligation.

46

The funded status of the plan and the net amount recognized in the accompanying balance sheets as of August 31 is as follows:

	August 31,
$ in thousands	2012			2011

	August 31,
$ in thousands	2012			2011
Net actuarial loss	$	(4,101	)	$	(3,445	)

For the years ended August 31, 2012 and 2011, the Company assumed a discount rate of 3.75 percent and 5.00 percent, respectively, for the determination of the liability. The assumptions used to determine benefit obligations and costs are selected based on current and expected market conditions. The discount rate is based on a hypothetical portfolio of long-term corporate bonds with cash flows approximating the timing of expected benefit payments.

For the years ended August 31, 2012, 2011 and 2010, the Company assumed a discount rate of 5.00 percent, 5.00 percent and 5.25 percent, respectively, for the determination of the net periodic benefit cost. The components of the net periodic benefit cost for the supplemental retirement plan for the years ended August 31 are as follows:

	For the years ended August 31,
$ in thousands	2012		2011		2010
Interest cost	$	325	$	334	$	351
Net amortization and deferral		166		164		178
Total	$	491	$	498	$	529

The estimated actuarial loss for the supplemental retirement plan that will be amortized, on a pre-tax basis, from accumulated other comprehensive loss into net periodic benefit cost during fiscal 2013 will be $212.

The Company’s future annual contributions to the supplemental retirement plan will be equal to expected net benefit payments since the plan is unfunded. The following net benefit payments are expected to be paid:

Fiscal Years	$ in thousands
2013		557
2014		541

N. WARRANTIES

Product Warranties

The Company generally warrants its products against certain manufacturing and other defects. These product warranties are provided for specific periods and/or usage of the product. The accrued product warranty costs are for a combination of specifically identified items and other incurred, but not identified, items based primarily on historical experience of actual warranty claims. This reserve is classified within other current liabilities.

The following tables provide the changes in the Company’s product warranties:

	For the years ended August 31,

Warranty costs were $4.9 million, $4.9 million, and $3.8 million for the fiscal years ended August 31, 2012, 2011 and 2010, respectively.

O. 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 accounting policies of the two reportable segments are described in the “Accounting Policies” section of Note A. 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 and other overhead charges directly attributable to the segment. There are no inter-segment sales.

The Company has no single major customer representing 10 percent or more of its total revenues during fiscal 2012, 2011, or 2010.

P. SHARE BASED COMPENSATION

Share Based Compensation Program

Share based compensation is designed to reward employees for their long-term contributions to the Company and provide incentives for them to remain with the Company. The number and frequency of share grants are based on competitive practices, operating results of the Company, and individual performance. As of August 31, 2012, the Company’s share-based compensation plan was the 2010 Long-Term Incentive Plan (the “2010 Plan”). The 2010 Plan was approved by the stockholders of the Company, and became effective on January 25, 2010, and replaced the Company’s 2006 Long Term Incentive Plan. At August 31, 2012 the Company had share based awards outstanding under its 2001, 2006 and 2010 Long-Term Incentive Plans.

The 2010 Plan 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. The maximum number of shares as to which stock awards may be granted under the 2010 Plan is 435,000 shares, exclusive of any forfeitures from the 2001 and 2006 Long Term Incentive Plans. At August 31, 2012, 297,962 shares of common stock (including forfeitures from prior plans) remained available for issuance under the 2010 Plan. All stock awards will be counted against the 2010 Plan in a 1 to 1 ratio. If options, restricted stock units or performance stock units awarded under the 2006 Plan or the 2001 Plan terminate without being fully vested or exercised, those shares will be available again for grant under the 2010 Plan. The 2010 Plan also limits the total awards that may be made to any individual.

Share Based Compensation Information

Stock Options – Stock option awards granted under the 2010 Plan have an exercise price equal to the closing price on the date of grant, expire no later than ten years from the date of grant and vest over a four-year period at 25 percent per year. The fair value of stock option awards is estimated using the Black-Scholes option pricing model. The table below shows the annual weighted-average assumptions used for valuation purposes.

	Grant Year
	Fiscal 2012
Weighed-Average Assumptions
Risk-free interest rate		1.7	%
Dividend yield		0.6	%
Expected life (years)		7
Volatility		55.9	%
Weighted-average grant-date fair value of options granted		$31.04

There were no stock option awards granted for the years ended August 31, 2011 or 2010. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant; the dividend yield is calculated as the ratio of dividends paid per share of common stock to the stock price on the date of grant; the expected life is based on historical and expected exercise behavior; and volatility is based on the historical volatility of the Company’s stock price over the expected life of the option.

Tax benefit realized from stock option exercises	$	368	$	2,628	$	232
Aggregate grant-date fair value of stock options vested		N/A	$	8.13	$	9.72

Restricted stock units – The restricted stock units granted to employees and directors under the 2010 Plan have a grant date fair value equal to the fair market value of the underlying stock on the grant date less present value of expected dividends. The restricted stock units granted to employees vest over a three-year period at approximately 33 percent per year. The restricted stock units granted to non-employee directors generally vest over a nine-month period.

The following table summarizes information about restricted stock units as of and for the years ended August 31, 2012, 2011 and 2010:

	Number of Shares			Weighted- Average Grant- Date Fair Value
Restricted stock units at August 31, 2010		75,093		$	38.61
Granted		40,699			55.27
Vested		(40,337	)		43.91

Forfeited		(7,122	)		51.16
Restricted stock units at August 31, 2012		67,535		$	54.35

51

Restricted stock units are generally settled with the issuance of shares with the exception of certain restricted stock units awarded to internationally-based employees that are settled in cash. At August 31, 2012, 2011 and 2010, outstanding restricted stock units included 4,873, 5,658 and 7,546 units, respectively, that will be settled in cash. The vesting date fair value of restricted stock units that vested was $1.7 million for each of the years ended August 31, 2012 and 2011.

Performance stock units – The performance stock units granted to employees under the 2010 Plan have a grant date fair value equal to the fair market value of the underlying stock on the grant date less present value of expected dividends. The performance stock units granted to employees cliff vest after a three-year period and a specified number of shares of common stock will be awarded under the terms of the performance stock units, if performance measures relating to three-year average revenue growth and a three-year average return on net assets are achieved.

The table below summarizes the status of the Company’s performance stock units as of and for the year ended August 31, 2012, 2011 and 2010:

	Number of Shares			Weighted- Average Grant- Date Fair Value
Performance stock units at August 31, 2010		87,701		$	38.98
Granted		27,932			55.45
Vested		(17,008	)		47.27

Vested		—			—
Forfeited		(38,987	)		43.30
Performance stock units at August 31, 2012		79,024		$	45.32

In connection with the performance stock units, the performance goals are based upon a three-year average revenue growth and a three-year average return on net assets over the performance period. The awards actually earned will range from zero to two hundred percent of the targeted number of performance stock units and will be paid in shares of common stock. Shares earned will be distributed upon vesting on the first day of November following the end of the three-year performance period. 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. If defined performance goals are not met, no compensation cost will be recognized and any previously recognized compensation expense will be reversed. Performance stock units that vested in fiscal 2011 represented 13,395 actual shares of common stock issued. No shares vested in fiscal 2012 as performance measures were not met. The vesting date fair value of performance stock units that vested was $0.6 million for the year ended August 31, 2011.

As of August 31, 2012, there was $4.7 million pre-tax of total unrecognized compensation cost related to nonvested share-based compensation arrangements which is expected to be recognized over a weighted-average period of 1.9 years.

We have audited Lindsay Corporation’s internal control over financial reporting as of August 31, 2012, based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying management’s report on internal control over financial reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

54

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

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

In our opinion, Lindsay Corporation maintained, in all material respects, effective internal control over financial reporting as of August 31, 2012, based on criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Lindsay Corporation and subsidiaries as of August 31, 2012 and 2011, and the related consolidated statements of operations, shareholders’ equity and comprehensive income, and cash flows for each of the years in the three-year period ended August 31, 2012, and our report dated October 26, 2012 expressed an unqualified opinion on those consolidated financial statements.

Description Of Business And Significant Accounting Policies [Abstract]

Priniciples Of Consolidation

(1) Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany balances and transactions are eliminated in consolidation.

Reclassifications

(2) Reclassifications

Certain reclassifications have been made to prior financial statements to conform to the current-year presentation.

Stock Based Compensation

(3) Stock Based Compensation

The Company recognizes compensation expense for all share-based payment awards made to employees and directors based on estimated fair values on the date of grant.  The Company uses the straight-line amortization method over the vesting period of the awards.  The Company has historically issued shares upon exercise of stock options or vesting of restricted stock units or performance stock units from new stock issuances, except for certain non-plan option shares granted in March 2000 that are issued from Treasury Stock upon exercise.  All outstanding non-plan option shares were exercised in fiscal 2010.

The value of the portion of the award that is ultimately expected to vest is recognized as expense in the Company’s 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 uses the Black-Scholes option-pricing model (“Black-Scholes model”) as its valuation method for stock option awards.  Under the Black-Scholes model, the fair value of stock option awards on the date of grant is estimated using an option-pricing model that is affected by the Company’s stock price as well as assumptions regarding a number of highly complex and subjective variables.  These variables include, but are not limited to the Company’s expected stock price volatility over the term of the awards and actual and projected employee stock option exercise behaviors.  Restricted stock, restricted stock units, performance shares and performance stock units issued under the 2010 Long-Term Incentive Plan will have a grant date fair value equal to the fair market value of the underlying stock on the grant date less present value of expected dividends.

Revenue Recognition

(4) Revenue Recognition

The Company’s basic criteria necessary for revenue recognition are: 1) evidence of a sales arrangement exists, 2) delivery of goods has occurred, 3) the seller's price to the buyer is fixed or determinable, and 4) collectability is reasonably assured. The Company recognizes revenue when these criteria have been met and when title and risk of loss transfers to the customer.  The Company generally has no post delivery obligations to its independent dealers other than standard warranties.  Revenues and gross profits on intercompany sales are eliminated in consolidation.If an arrangement involves multiple deliverables, the delivered items are considered separate units of accounting if the items have value on a stand-alone basis and there is objective and reliable evidence of their fair values. Revenues from the arrangement are allocated to the separate units of accounting based on their objectively determined fair value.

The costs related to revenues are recognized in the same period in which the specific revenues are recorded.  Shipping and handling fees billed to customers are reported in revenue. Shipping and handling costs incurred by the Company are included in cost of sales. Customer rebates, cash discounts and other sales incentives are recorded as a reduction of revenues at the time of the original sale.  Estimates used in the recognition of operating revenues and cost of operating revenues include, but are not limited to, estimates for product warranties, product rebates, cash discounts and fair value of separate units of accounting on multiple deliverables.

Receivables And Allowances

(5) Receivables and Allowances

Trade receivables are reported on the balance sheet net of any doubtful accounts. Allowances for doubtful accounts are maintained in amounts considered to be appropriate in relation to the receivables outstanding based on collection experience, economic conditions and credit risk quality.

Warranty Costs

(6) Warranty Costs

The Company's provision for product warranty reflects management's best estimate of probable liability under its product warranties.  At the time a sale is recognized, the company records the estimated future warranty costs. The Company generally determines its total future warranty liability by applying historical claims rate experience to the amount of equipment that has been sold and is still within the warranty period.  In addition, the Company records provisions for known warranty claims.  This provision is periodically adjusted to reflect actual experience.

Cash And Cash Equivalents

(7) Cash and Cash Equivalents

Cash equivalents consist of investments with original maturities of three months or less.

Inventories

(8) 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 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.  At all locations, the Company reserves for obsolete, slow moving, and excess inventory by estimating the net realizable value based on the potential future use of such inventory.

Property, Plant And Equipment

(9) Property, Plant and Equipment

Property, plant, equipment, and capitalized assets held for lease are stated at cost.  The Company capitalizes major expenditures and charges to operating expenses the cost of current maintenance and repairs.  Provisions for depreciation and amortization have been computed principally on the straight-line method for buildings and equipment.  Rates used for depreciation are based principally on the following expected lives: buildings ‑‑ 15 to 30 years; temporary structures -- 5 years; equipment ‑‑ 3 to 10 years; leased Barrier Transfer Machines -- 8 to 10 years; leased barriers -- 12 years; other ‑‑ 2to 20 years and leasehold improvements – shorter of the economic life or term of the lease.  All of the Company's long‑lived asset groups are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the sum of the expected future cash flows is less than the carrying amount of the asset group, an impairment loss is recognized based upon the difference between the fair value of the asset and its carrying value.  During fiscal 2012, 2011 and 2010 no impairment losses were recognized.  The cost and accumulated depreciation relating to assets retired or otherwise disposed of are eliminated from the respective accounts at the time of disposition.  The resulting gain or loss is included in operating income in the consolidated statements of operations. 

Goodwill And Intangible Assets

(10) Goodwill and Intangible Assets

Goodwill represents the excess of the purchase price over the fair value of net assets acquired in a business combination.  Acquired intangible assets are recognized separately from goodwill.  Goodwill and intangible assets with indefinite useful lives are tested for impairment at least annually at August 31 and whenever triggering events or changes in circumstances indicate its carrying value may not be recoverable. The Company performs the impairment analysis at the reporting unit level using a two-step impairment test. Fair value is typically estimated using a discounted cash flow analysis, which requires the Company to estimate the future cash flows anticipated to be generated by the particular assets being tested for impairment as well as a discount rate to measure the present value of the anticipated cash flows. When determining future cash flow estimates, the Company considers historical results adjusted to reflect current and anticipated operating conditions. Estimating future cash flows requires significant judgment and assumptions by management in such areas as future economic conditions, industry-specific conditions, product pricing, and necessary capital expenditures. To the extent that the reporting unit is unable to achieve these assumptions, impairment losses may emerge. 

Income Taxes

(11) Income Taxes

Income taxes are accounted for utilizing the asset and liability method of accounting for income taxes.  Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying value of existing assets and liabilities and their respective tax bases.  These expected future tax consequences are measured based on currently enacted tax rates.  The effect of tax rate changes on deferred tax assets and liabilities is recognized in income during the period that includes the enactment date. 

When the Company has claimed tax benefits that may be challenged by a tax authority, the Company recognizes tax benefits only for tax positions that are more likely than not to be sustained upon examination by tax authorities. The amount recognized is measured as the largest amount of benefit that is greater than 50 percent likely to be realized upon settlement. A liability for “unrecognized tax benefits” is recorded for any tax benefits claimed in the Company’s tax returns that do not meet these recognition and measurement standards.

Net Earnings Per Share

(12) 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. Under the treasury stock method, the amount the employee must pay for exercising stock options, the amount of compensation cost for future service that the Company has not yet recognized, and the amount of excess tax benefits that would be recorded in additional paid-in-capital when exercised are assumed to be used  to repurchase shares.

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

	For the years ended August 31,
	2012	2011	2010
Restricted stock units	3,241	2,062	476
Stock options	29,181	-	-

Performance stock units are excluded from the calculation of dilutive potential common shares until the threshold performance conditions have been satisfied.  At August 31, 2012 and 2010, the threshold performance conditions for certain performance stock units had been satisfied resulting in the inclusion of 37,746 and 13,395, respectively, of performance stock units in the calculation of diluted net earnings per share. At August 31, 2011, the threshold performance conditions for certain performance stock units had not been satisfied. At August 31, 2012, 2011 and 2010, there were 43,388,  98,625 and 70,693, respectively, of performance stock units excluded from the calculation of diluted net earnings per share because the threshold performance conditions had not been satisfied. 

Use Of Estimates

(13) Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.

Derivative Instruments And Hedging Activities

(14) Derivative Instruments and Hedging Activities

The Company uses certain financial derivatives to mitigate its exposure to volatility in interest rates and foreign currency exchange rates.  All derivative instruments are recorded on the balance sheet at their respective fair values. The Company uses these derivative instruments only to hedge exposures in the ordinary course of business and does not invest in derivative instruments for speculative purposes.  On the date a derivative contract is entered into, the Company may elect to designate the derivative as a fair value hedge, a cash flow hedge, or the hedge of a net investment in a foreign operation.

The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivative that is used in the hedging transaction is highly effective. For those 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 earnings.  All changes in derivative fair values due to ineffectiveness are recognized currently in income.

The Company discontinues hedge accounting prospectively when it is determined that the derivative is no longer effective in offsetting changes in the cash flows of the hedged item, the derivative expires or is sold, terminated, or exercised, or management determines that designation of the derivative as a hedging instrument is no longer appropriate.In situations in which the Company does not elect hedge accounting or hedge accounting is discontinued and the derivative is retained, the Company carries or continues to carry the derivative at its fair value on the balance sheet and recognizes any subsequent changes in its fair value through 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 August 31, 2012, the Company’s derivative counterparty had investment grade credit ratings.

Fair Value Measurements

.

(15) Fair Value Measurements

The Company’s disclosure of the fair value of assets and liabilities is based on a three-level hierarchy for fair value measurements based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. Inputs refers broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk. The categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Financial assets and liabilities carried at fair value will be classified and disclosed in one of the following three categories:

- Level 1 – inputs to the valuation techniques are quoted prices in active markets for identical assets or liabilities 

- Level 2 – inputs to the valuation techniques are other than quoted prices but are observable for the assets or liabilities, either directly or indirectly 

- Level 3 – inputs to the valuation techniques are unobservable for the assets or liabilities 

The following table presents the Company’s financial assets and liabilities measured at fair value based upon the level within the fair value hierarchy in which the fair value measurements fall, as of August 31, 2012 and 2011, respectively:  

		August 31, 2012
$ in thousands		Level 1		Level 2		Level 3		Total
Cash and cash equivalents	$	143,444	$	-	$	-	$	143,444
Derivative Assets	$	-	$	12	$	-	$	12
Derivative Liabilities	$	-	$	(563)	$	-	$	(563)
		August 31, 2011
$ in thousands		Level 1		Level 2		Level 3		Total
Cash and cash equivalents	$	108,167	$	-	$	-	$	108,167
Derivative Liabilities	$	-	$	(634)	$	-	$	(634)

The carrying amount of long-term debt (including current portion) was $4.3 million and $8.6 million as of August 31, 2012 and 2011, respectively.  The fair value of this debt at August 31, 2012 and 2011, was estimated at $4.3 million and $8.5 million, 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. Goodwill is tested for impairment annually or whenever there is an impairment indicator. All goodwill is assigned to a reporting unit, where it is subject to an impairment test based on fair value using Level 3 input as defined in the fair value hierarchy. 

Treasury Stock

(16) Treasury Stock

When the Company repurchases its outstanding stock, it records the repurchased shares at cost as a reduction to shareholders’ equity.  The weighted average cost method is utilized for share re-issuances.  The difference between the cost and the re-issuance price is charged or credited to a “capital in excess of stated value – treasury stock” account to the extent that there is a sufficient balance to absorb the charge.  If the treasury stock is sold for an amount less than its cost and there is not a sufficient balance in the capital in excess of stated value – treasury stock account, the excess is charged to retained earnings.

Contingencies

(17) Contingencies

The Company’s accounting for contingencies covers a variety of business activities including contingencies for legal exposures and environmental exposures. The Company accrues these contingencies when its assessments indicate that it is probable that a liability has been incurred and an amount can be reasonably estimated. The Company’s estimates are based on currently available facts and its estimates of the ultimate outcome or resolution. Actual results may differ from the Company’s estimates resulting in an impact, positive or negative, on earnings.

Translation Of Foreign Currency

(18) Translation of Foreign Currency

The Company’s portion of the assets and liabilities related to foreign investments are translated into U.S. dollars at the exchange rates in effect at the balance sheet date.  Revenue and expenses are translated at the average rates of exchange prevailing during the year.  Unrealized gains or losses are reflected within common shareholders’ equity as accumulated other comprehensive income or loss.

Description Of Business And Significant Accounting Policies

A. DESCRIPTION OF BUSINESSAND SIGNIFICANT ACCOUNTING POLICIES

Lindsay Corporation, along with its subsidiaries (collectively called "Lindsay" or the "Company"), is a global leader in providing a variety of proprietary water management and road infrastructure products and services. The Company has been involved in the manufacture and distribution of agricultural equipment since 1955 and has grown from a regional company to an international agribusiness and highway infrastructure firm with worldwide sales and distribution. Lindsay, a Delaware corporation, maintains its corporate offices in Omaha, Nebraska.  The Company has operations which are categorized into two major reporting segments.

Irrigation Segment – The Company’s irrigation segment includes the manufacture and marketing of center pivot, lateral move, and hose reel irrigation systems which are used principally in the agricultural industry to increase or stabilize crop production while conserving water, energy, and labor.  The irrigation segment also manufactures and markets repair and replacement parts for its irrigation systems and controls, and designs, manufactures and services water pumping stations and controls for the agriculture, golf, landscape and municipal markets.  The Company continues to strengthen irrigation product offerings through innovative technology such as GPS positioning and guidance, variable rate irrigation, wireless irrigation management, and smartphone application.  The Company’s principal irrigation manufacturing facilities are located in Lindsay, Nebraska and Hartland, Wisconsin.  Internationally, the Company has production operations in France, Brazil and China as well as distribution operations in South Africa, Australia and New Zealand. The Company also exports some of its equipment from the U.S. to other international markets. 

Infrastructure Segment – The Company’s infrastructure segment includes the manufacture and marketing of moveable barriers, specialty barriers, crash cushions and end terminals, road marking and road safety equipment, large diameter steel tubing, railroad signals and structures, and outsourced manufacturing services.  The principal infrastructure manufacturing facilities are located in Rio Vista, California, Milan, Italy, and Omaha, Nebraska.

Notes to the consolidated financial statements describe various elements of the financial statements and the accounting policies, estimates, and assumptions applied by management.  While actual results could differ from those estimated at the time of preparation of the consolidated financial statements, management believes that the accounting policies, assumptions, and estimates applied promote the representational faithfulness, verifiability, neutrality, and transparency of the accounting information included in the consolidated financial statements.

The significant accounting policies of the Company are as follows:

(1) Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany balances and transactions are eliminated in consolidation.

(2) Reclassifications

Certain reclassifications have been made to prior financial statements to conform to the current-year presentation.

(3) Stock Based Compensation

The Company recognizes compensation expense for all share-based payment awards made to employees and directors based on estimated fair values on the date of grant.  The Company uses the straight-line amortization method over the vesting period of the awards.  The Company has historically issued shares upon exercise of stock options or vesting of restricted stock units or performance stock units from new stock issuances, except for certain non-plan option shares granted in March 2000 that are issued from Treasury Stock upon exercise.  All outstanding non-plan option shares were exercised in fiscal 2010.

The value of the portion of the award that is ultimately expected to vest is recognized as expense in the Company’s 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 uses the Black-Scholes option-pricing model (“Black-Scholes model”) as its valuation method for stock option awards.  Under the Black-Scholes model, the fair value of stock option awards on the date of grant is estimated using an option-pricing model that is affected by the Company’s stock price as well as assumptions regarding a number of highly complex and subjective variables.  These variables include, but are not limited to the Company’s expected stock price volatility over the term of the awards and actual and projected employee stock option exercise behaviors.  Restricted stock, restricted stock units, performance shares and performance stock units issued under the 2010 Long-Term Incentive Plan will have a grant date fair value equal to the fair market value of the underlying stock on the grant date less present value of expected dividends.

(4) Revenue Recognition

The Company’s basic criteria necessary for revenue recognition are: 1) evidence of a sales arrangement exists, 2) delivery of goods has occurred, 3) the seller's price to the buyer is fixed or determinable, and 4) collectability is reasonably assured. The Company recognizes revenue when these criteria have been met and when title and risk of loss transfers to the customer.  The Company generally has no post delivery obligations to its independent dealers other than standard warranties.  Revenues and gross profits on intercompany sales are eliminated in consolidation.If an arrangement involves multiple deliverables, the delivered items are considered separate units of accounting if the items have value on a stand-alone basis and there is objective and reliable evidence of their fair values. Revenues from the arrangement are allocated to the separate units of accounting based on their objectively determined fair value.

The costs related to revenues are recognized in the same period in which the specific revenues are recorded.  Shipping and handling fees billed to customers are reported in revenue. Shipping and handling costs incurred by the Company are included in cost of sales. Customer rebates, cash discounts and other sales incentives are recorded as a reduction of revenues at the time of the original sale.  Estimates used in the recognition of operating revenues and cost of operating revenues include, but are not limited to, estimates for product warranties, product rebates, cash discounts and fair value of separate units of accounting on multiple deliverables.

(5) Receivables and Allowances

Trade receivables are reported on the balance sheet net of any doubtful accounts. Allowances for doubtful accounts are maintained in amounts considered to be appropriate in relation to the receivables outstanding based on collection experience, economic conditions and credit risk quality.

(6) Warranty Costs

The Company's provision for product warranty reflects management's best estimate of probable liability under its product warranties.  At the time a sale is recognized, the company records the estimated future warranty costs. The Company generally determines its total future warranty liability by applying historical claims rate experience to the amount of equipment that has been sold and is still within the warranty period.  In addition, the Company records provisions for known warranty claims.  This provision is periodically adjusted to reflect actual experience.

(7) Cash and Cash Equivalents

Cash equivalents consist of investments with original maturities of three months or less.

(8) 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 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.  At all locations, the Company reserves for obsolete, slow moving, and excess inventory by estimating the net realizable value based on the potential future use of such inventory.

(9) Property, Plant and Equipment

Property, plant, equipment, and capitalized assets held for lease are stated at cost.  The Company capitalizes major expenditures and charges to operating expenses the cost of current maintenance and repairs.  Provisions for depreciation and amortization have been computed principally on the straight-line method for buildings and equipment.  Rates used for depreciation are based principally on the following expected lives: buildings ‑‑ 15 to 30 years; temporary structures -- 5 years; equipment ‑‑ 3 to 10 years; leased Barrier Transfer Machines -- 8 to 10 years; leased barriers -- 12 years; other ‑‑ 2to 20 years and leasehold improvements – shorter of the economic life or term of the lease.  All of the Company's long‑lived asset groups are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the sum of the expected future cash flows is less than the carrying amount of the asset group, an impairment loss is recognized based upon the difference between the fair value of the asset and its carrying value.  During fiscal 2012, 2011 and 2010 no impairment losses were recognized.  The cost and accumulated depreciation relating to assets retired or otherwise disposed of are eliminated from the respective accounts at the time of disposition.  The resulting gain or loss is included in operating income in the consolidated statements of operations. 

(10) Goodwill and Intangible Assets

Goodwill represents the excess of the purchase price over the fair value of net assets acquired in a business combination.  Acquired intangible assets are recognized separately from goodwill.  Goodwill and intangible assets with indefinite useful lives are tested for impairment at least annually at August 31 and whenever triggering events or changes in circumstances indicate its carrying value may not be recoverable. The Company performs the impairment analysis at the reporting unit level using a two-step impairment test. Fair value is typically estimated using a discounted cash flow analysis, which requires the Company to estimate the future cash flows anticipated to be generated by the particular assets being tested for impairment as well as a discount rate to measure the present value of the anticipated cash flows. When determining future cash flow estimates, the Company considers historical results adjusted to reflect current and anticipated operating conditions. Estimating future cash flows requires significant judgment and assumptions by management in such areas as future economic conditions, industry-specific conditions, product pricing, and necessary capital expenditures. To the extent that the reporting unit is unable to achieve these assumptions, impairment losses may emerge. 

(11) Income Taxes

Income taxes are accounted for utilizing the asset and liability method of accounting for income taxes.  Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying value of existing assets and liabilities and their respective tax bases.  These expected future tax consequences are measured based on currently enacted tax rates.  The effect of tax rate changes on deferred tax assets and liabilities is recognized in income during the period that includes the enactment date. 

When the Company has claimed tax benefits that may be challenged by a tax authority, the Company recognizes tax benefits only for tax positions that are more likely than not to be sustained upon examination by tax authorities. The amount recognized is measured as the largest amount of benefit that is greater than 50 percent likely to be realized upon settlement. A liability for “unrecognized tax benefits” is recorded for any tax benefits claimed in the Company’s tax returns that do not meet these recognition and measurement standards.

(12) 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. Under the treasury stock method, the amount the employee must pay for exercising stock options, the amount of compensation cost for future service that the Company has not yet recognized, and the amount of excess tax benefits that would be recorded in additional paid-in-capital when exercised are assumed to be used  to repurchase shares.

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

	For the years ended August 31,
	2012	2011	2010
Restricted stock units	3,241	2,062	476
Stock options	29,181	-	-

Performance stock units are excluded from the calculation of dilutive potential common shares until the threshold performance conditions have been satisfied.  At August 31, 2012 and 2010, the threshold performance conditions for certain performance stock units had been satisfied resulting in the inclusion of 37,746 and 13,395, respectively, of performance stock units in the calculation of diluted net earnings per share. At August 31, 2011, the threshold performance conditions for certain performance stock units had not been satisfied. At August 31, 2012, 2011 and 2010, there were 43,388,  98,625 and 70,693, respectively, of performance stock units excluded from the calculation of diluted net earnings per share because the threshold performance conditions had not been satisfied. 

(13) Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  Actual results could differ from those estimates.

(14) Derivative Instruments and Hedging Activities

The Company uses certain financial derivatives to mitigate its exposure to volatility in interest rates and foreign currency exchange rates.  All derivative instruments are recorded on the balance sheet at their respective fair values. The Company uses these derivative instruments only to hedge exposures in the ordinary course of business and does not invest in derivative instruments for speculative purposes.  On the date a derivative contract is entered into, the Company may elect to designate the derivative as a fair value hedge, a cash flow hedge, or the hedge of a net investment in a foreign operation.

The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the derivative that is used in the hedging transaction is highly effective. For those 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 earnings.  All changes in derivative fair values due to ineffectiveness are recognized currently in income.

The Company discontinues hedge accounting prospectively when it is determined that the derivative is no longer effective in offsetting changes in the cash flows of the hedged item, the derivative expires or is sold, terminated, or exercised, or management determines that designation of the derivative as a hedging instrument is no longer appropriate.In situations in which the Company does not elect hedge accounting or hedge accounting is discontinued and the derivative is retained, the Company carries or continues to carry the derivative at its fair value on the balance sheet and recognizes any subsequent changes in its fair value through 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 August 31, 2012, the Company’s derivative counterparty had investment grade credit ratings.

(15) Fair Value Measurements

The Company’s disclosure of the fair value of assets and liabilities is based on a three-level hierarchy for fair value measurements based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. Inputs refers broadly to the assumptions that market participants would use in pricing the asset or liability, including assumptions about risk. The categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Financial assets and liabilities carried at fair value will be classified and disclosed in one of the following three categories:

- Level 1 – inputs to the valuation techniques are quoted prices in active markets for identical assets or liabilities 

- Level 2 – inputs to the valuation techniques are other than quoted prices but are observable for the assets or liabilities, either directly or indirectly 

- Level 3 – inputs to the valuation techniques are unobservable for the assets or liabilities 

The following table presents the Company’s financial assets and liabilities measured at fair value based upon the level within the fair value hierarchy in which the fair value measurements fall, as of August 31, 2012 and 2011, respectively:  

		August 31, 2012
$ in thousands		Level 1		Level 2		Level 3		Total
Cash and cash equivalents	$	143,444	$	-	$	-	$	143,444
Derivative Assets	$	-	$	12	$	-	$	12
Derivative Liabilities	$	-	$	(563)	$	-	$	(563)
		August 31, 2011
$ in thousands		Level 1		Level 2		Level 3		Total
Cash and cash equivalents	$	108,167	$	-	$	-	$	108,167
Derivative Liabilities	$	-	$	(634)	$	-	$	(634)

The carrying amount of long-term debt (including current portion) was $4.3 million and $8.6 million as of August 31, 2012 and 2011, respectively.  The fair value of this debt at August 31, 2012 and 2011, was estimated at $4.3 million and $8.5 million, 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. Goodwill is tested for impairment annually or whenever there is an impairment indicator. All goodwill is assigned to a reporting unit, where it is subject to an impairment test based on fair value using Level 3 input as defined in the fair value hierarchy. 

(16) Treasury Stock

When the Company repurchases its outstanding stock, it records the repurchased shares at cost as a reduction to shareholders’ equity.  The weighted average cost method is utilized for share re-issuances.  The difference between the cost and the re-issuance price is charged or credited to a “capital in excess of stated value – treasury stock” account to the extent that there is a sufficient balance to absorb the charge.  If the treasury stock is sold for an amount less than its cost and there is not a sufficient balance in the capital in excess of stated value – treasury stock account, the excess is charged to retained earnings.

(17) Contingencies

The Company’s accounting for contingencies covers a variety of business activities including contingencies for legal exposures and environmental exposures. The Company accrues these contingencies when its assessments indicate that it is probable that a liability has been incurred and an amount can be reasonably estimated. The Company’s estimates are based on currently available facts and its estimates of the ultimate outcome or resolution. Actual results may differ from the Company’s estimates resulting in an impact, positive or negative, on earnings.

(18) Translation of Foreign Currency

The Company’s portion of the assets and liabilities related to foreign investments are translated into U.S. dollars at the exchange rates in effect at the balance sheet date.  Revenue and expenses are translated at the average rates of exchange prevailing during the year.  Unrealized gains or losses are reflected within common shareholders’ equity as accumulated other comprehensive income or loss.

Industry Segment Information

O.  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 accounting policies of the two reportable segments are described in the “Accounting Policies” section of Note A.  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 and other overhead charges directly attributable to the segment.  There are no inter-segment sales. 

The Company has no single major customer representing 10 percent or more of its total revenues during fiscal 2012, 2011, or 2010.

Credit Arrangements

J. CREDIT ARRANGEMENTS

Euro Line of Credit

The Company’s wholly-owned European subsidiary, Lindsay Europe SAS, 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”).  There were no borrowings outstanding on this credit agreement at August 31, 2012 or 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, (1.38 percent at August 31, 2012). Unpaid principal and interest is due by January 31, 2013.  The Company intends to renew the Euro Line of Credit upon expiration of its term.

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  (0.65percent at August 31, 2012). The Company effectively fixed the economic effect of the variable interest rate at 6.05 percent through an interest rate swap as described in Note K, Financial Derivatives.  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 in June of 2013. 

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 August 31, 2012 and 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  (1.28percent at August 31, 2012), 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 similar 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 August 31, 2012 and 2011, the Companywas in compliance with all loan covenants. 

Long-term debt consists of the following:

	August 31,
$ in thousands	2012		2011
BSI Term Note	$	4,285	$	8,571
Less current portion		(4,285)		(4,286)
Total long-term debt	$	-	$	4,285

Interest expense was $0.5million, $0.8 million and $1.6 million for the years ended August 31, 2012, 2011 and 2010, respectively.  All remaining principal payments on the term note are due within one year.

In addition, accumulated other comprehensive income included gains, net of related income tax effects of $2.4 million and $0.5 million at August 31, 2012 and 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 effectively convert or hedge the variable interest rate on the entire amount of this borrowing to achieve a  net 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 (see Note J, Credit Arrangements).  Changes in the fair value of the interest rate swap designated as the hedging instrument that effectively offset the variability of cash flows associated with the variable-rate, long-term debt obligation 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 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 $3.0 million and $0.0million of U.S. dollar equivalent cash flow forward exchange contracts and option contracts outstanding as of August 31, 2012 and 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.

(1)Net of tax expense (benefit) of $1,023,  ($489) and $181 for the years ended August 31, 2012, 2011 and 2010, respectively.

During fiscal 2012, 2011 and 2010, the Company settled Euro foreign currency forward contracts resulting in after-tax net gains (losses) of $1.8 million, ($0.7 million) and $0.3 million, respectively, which were included in OCI as part of a currency translation adjustment.  There were no amounts recorded in the consolidated statement of operations related to ineffectiveness of Euro foreign currency forward contracts for the years ended August 31, 2012, 2011 and 2010.  Accumulated currency translation adjustment in AOCI at August 31, 2012, 2011 and 2010 reflected realized and unrealized after-tax gains of $2.4 million, $0.7 million and $1.5 million, respectively.

At August 31, 2012 and 2011, the Company had outstanding Euro foreign currency forward contracts to sell 26.5 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.

In fiscal 2010, the Company recognized investment tax credits from the state of Nebraska’s economic development program, the Nebraska Advantage Act.  These credits, which expire in fiscal 2018, reduced income tax expense by $1.4 million. 

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Company's deferred tax assets and liabilities are as follows:

	August 31,
$ in thousands	2012		2011
Deferred tax assets:
Deferred rental revenue	$	382	$	1,233

Total deferred tax liabilities		(14,816)		(17,313)
Net deferred tax liabilities	$	171	$	(3,683)

In assessing the ability to realize deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized.  The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible.  Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment.  Based upon the level of historical taxable income and projections for future taxable income over the periods in which the deferred tax assets are deductible, management believes it is more likely than not that the Company will realize the benefits of these deductible differences.  Accordingly, a valuation allowance for deferred tax assets at August 31, 2012 and 2011 has not been established.

The determination of the unrecognized deferred tax liability for permanently reinvested foreign earnings is not practical as the Company does not intend to repatriate earnings of its non-U.S. subsidiaries and accordingly, has not provided a U.S. deferred income tax liability for cumulative earnings on non-U.S. affiliates and associated companies that have been reinvested indefinitely.The Company continues to analyze the potential tax impact should it elect to repatriate non-U.S. earnings and would recognize a deferred income tax liability if the Company were to determine that such earnings are no longer indefinitely reinvested.

The Company recognizes tax benefits only for tax positions that are more likely than not to be sustained upon examination by tax authorities.  The amount recognized is measured as the largest amount of benefit that is greater than 50 percent likely to be realized upon settlement. Unrecognized tax benefits are tax benefits claimed in the Company’s tax returns that do not meet these recognition and measurement standards.   

A reconciliation of changes in pre-tax unrecognized tax benefits is as follows:

	August 31,
$ in thousands	2012		2011
Unrecognized Tax Benefits at September 1	$	1,565	$	1,112
Increases for positions taken in current year		2		78
Increases for positions taken in prior years		61		448
Decreases for positions taken in prior years		(44)		-
Settlements with taxing authorities		(42)		-
Reduction resulting from lapse of applicable statute of limitations		(173)		(87)
Other increases (decreases)		(60)		14
Unrecognized Tax Benefits at August 31	$	1,309	$	1,565

The net amount of unrecognized tax benefits at August 31, 2012 and 2011 that, if recognized, would impact the Company’s effective tax rate was $1.3 million and $1.6 million, respectively. Recognition of these tax benefits would have a favorable impact on the Company’s effective tax rate.

The Company recognizes accrued interest and penalties related to unrecognized tax benefits in income tax expense. Total accrued pre-tax liabilities for interest and penalties included in the unrecognized tax benefits liability were $0.5 million and $0.5 million for the years ended August 31, 2012 and 2011, respectively.  

The Company files income tax returns in the U.S. federal jurisdiction, and various state and foreign jurisdictions. The Company is no longer subject to examination by tax authorities in most jurisdictions for years prior to 2009.  

While it is expected that the amount of unrecognized tax benefits will change in the next twelve months as a result of the expiration of statutes of limitations, the Company does not expect this change to have a significant impact on its results of operations or financial position.

Share Based Compensation [Abstract]

Share Based Compensation

P. SHARE BASED COMPENSATION

Share Based Compensation Program

Share based compensation is designed to reward employees for their long-term contributions to the Company and provide incentives for them to remain with the Company.  The number and frequency of share grants are based on competitive practices, operating results of the Company, and individual performance.  As of August 31, 2012, the Company’s share-based compensation plan was the 2010 Long-Term Incentive Plan (the “2010 Plan”).  The 2010 Plan was approved by the stockholders of the Company, and became effective on January 25, 2010, and replaced the Company’s 2006 Long Term Incentive Plan.  At August 31, 2012 the Company had share based awards outstanding under its 2001, 2006 and 2010 Long-Term Incentive Plans.  

The 2010 Plan 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.  The maximum number of shares as to which stock awards may be granted under the 2010 Plan is 435,000 shares, exclusive of any forfeitures from the 2001 and 2006 Long Term Incentive Plans.  At August 31, 2012, 297,962 shares of common stock (including forfeitures from prior plans) remained available for issuance under the 2010 Plan.  All stock awards will be counted against the 2010 Plan in a 1 to 1 ratio.  If options, restricted stock units or performance stock units awarded under the 2006 Plan or the 2001 Plan terminate without being fully vested or exercised, those shares will be available again for grant under the 2010 Plan.  The 2010 Plan also limits the total awards that may be made to any individual.   

Share Based Compensation Information 

Stock Options – Stock option awards granted under the 2010 Plan have an exercise price equal to the closing price on the date of grant, expire no later than ten years from the date of grant and vest over a four-year period at 25 percent per year.  The fair value of stock option awards is estimated using the Black-Scholes option pricing model.  The table below shows the annual weighted-average assumptions used for valuation purposes. 

		Grant Year
Weighed-Average Assumptions		Fiscal 2012
Risk-free interest rate		1.7%
Dividend yield		0.6%
Expected life (years)		7
Volatility		55.9%
Weighted-average grant-date fair value of options granted	$	31.04

There were no stock option awards granted for the years ended August 31, 2011 or 2010.  The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant; the dividend yield is calculated as the ratio of dividends paid per share of common stock to the stock price on the date of grant; the expected life is based on historical and expected exercise behavior; and volatility is based on the historical volatility of the Company’s stock price over the expected life of the option.

The following table summarizes information about stock options outstanding as of and for the years ended August 31, 2012, 2011 and 2010:

	Number of Shares	Average Exercise Price		Average Remaining Contractual Term (years)	Aggregate Intrinsic Value ('000s)

Restricted stock units are generally settled with the issuance of shares with the exception of certain restricted stock units awarded to internationally-based employees that are settled in cash.  At August 31, 2012, 2011 and 2010, outstanding restricted stock units included 4,873,  5,658and 7,546 units, respectively, that will be settled in cash.  The vesting date fair value of restricted stock units that vested was $1.7 million for each of the years ended August 31, 2012 and 2011. 

Performance stock units - The performance stock units granted to employees under the 2010 Plan have a grant date fair value equal to the fair market value of the underlying stock on the grant date less present value of expected dividends.  The performance stock units granted to employees cliff vest after a three-year period and a specified number of shares of common stock will be awarded under the terms of the performance stock units, if performance measures relating to three-year average revenue growth and a three-year average return on net assets are achieved. 

The table below summarizes the status of the Company’s performance stock units as of and for the year ended August 31, 2012, 2011 and 2010:

Performance stock units at August 31, 2012		79,024	$	45.32

In connection with the performance stock units, the performance goals are based upon a three-year average revenue growth and a three-year average return on net assets over the performance period.  The awards actually earned will range from zero to two hundred percent of the targeted number of performance stock units and will be paid in shares of common stock.  Shares earned will be distributed upon vesting on the first day of November following the end of the three-year performance period.  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.  If defined performance goals are not met, no compensation cost will be recognized and any previously recognized compensation expense will be reversed.  Performance stock units that vested in fiscal 2011 represented 13,395 actual shares of common stock issued.  No shares vested in fiscal 2012 as performance measures were not met. The vesting date fair value of performance stock units that vested was $0.6 million for the year ended August 31, 2011. 

As of August 31, 2012, there was $4.7 million pre-tax of total unrecognized compensation cost related to nonvested share-based compensation arrangements which is expected to be recognized over a weighted-average period of 1.9 years.

Commitments And Contingencies [Abstract]

Commitments And Contingencies

L. COMMITMENTS AND CONTINGENCIES

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.  No such current proceedings, individually or in the aggregate, are expected to have a material effect on the business or financial condition of the Company.

Environmental Remediation

In 1992, the Company entered into a consent decree with the U.S. Environmental Protection Agency (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 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 August 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 August 31, 2012 and 2011: 

Environmental Remediation Liabilities

Amortization expense for amortizable intangible assets was $2.9 million, $2.8 million and $2.6 million for 2012, 2011, and 2010,  respectively.  Amortizable intangible assets are being amortized using the straight-line method over an average term of approximately 11.3 years.   

Future estimated amortization of intangible assets for the next five years is as follows:

Fiscal Years	$ in thousands
2013	$	2,803
2014		2,748
2015		2,446

The Company updated its impairment evaluation of goodwill and intangible assets with indefinite useful lives at August 31, 2012.  The estimated fair value of all of the Company’s reporting units each exceeded the respective carrying values by more than 10 percent. Accordingly, no impairment losses were indicated as a result of the annual impairment testing for fiscal years 2012, 2011 and 2010. The Company does not include a roll forward of impairment losses because the Company has never had an impairment loss.

Retirement Plan [Abstract]

Retirement Plan

M. RETIREMENT PLANS

The Company has a defined contribution profit‑sharing plan covering substantially all of its full-time U.S. employees.  Participants may voluntarily contribute a percentage of compensation, but not in excess of the maximum allowed under the Internal Revenue Code.  The plan provides for a matching contribution by the Company.  The Company's total contributions charged to expense under this plan were $0.5 million, $0.5 million and  $0.6 millionfor the years ended August 31, 2012, 2011 and 2010, respectively. 

A supplementary non‑qualified, non‑funded retirement plan for six former executives is also maintained.  Plan benefits are based on the executive's average total compensation during the three highest compensation years of employment.  This unfunded supplemental retirement plan is not subject to the minimum funding requirements of ERISA.  The Company has purchased life insurance policies on certain former executives named in this supplemental retirement plan to provide funding for this liability.

As of August 31, 2012 and 2011, the funded status of the supplemental retirement plan was recorded in the consolidated balance sheets.  The Company utilizes an August 31 measurement date for plan obligations related to the supplemental retirement plan.  As this is an unfunded retirement plan, the funded status is equal to the benefit obligation. 

The funded status of the plan and the net amount recognized in the accompanying balance sheets as of August 31 is as follows: 

	August 31,
$ in thousands	2012		2011
Change in benefit obligation:
Benefit obligation at beginning of year	$	6,787	$	6,957
Interest cost		325		334
Actuarial loss		823		53
Benefits paid		(557)		(557)
Benefit obligation at end of year	$	7,378	$	6,787

Amounts recognized in the statement of financial position consist of:

	August 31,
$ in thousands	2012		2011
Other current liabilities	$	557	$	557
Pension benefit liabilities		6,821		6,230
Net amount recognized	$	7,378	$	6,787

The before-tax amounts recognized in accumulated other comprehensive loss as of August 31 consists of:

	August 31,
$ in thousands	2012		2011
Net actuarial loss	$	(4,101)	$	(3,445)

For the years ended August 31, 2012 and 2011, the Company assumed a discount rate of 3.75 percent and 5.00 percent, respectively, for the determination of the liability.  The assumptions used to determine benefit obligations and costs are selected based on current and expected market conditions.  The discount rate is based on a hypothetical portfolio of long-term corporate bonds with cash flows approximating the timing of expected benefit payments.

For the years ended August 31, 2012, 2011 and 2010, the Company assumed a discount rate of 5.00 percent, 5.00 percent and 5.25 percent, respectively, for the determination of the net periodic benefit cost.  The components of the net periodic benefit cost for the supplemental retirement plan for the years ended August 31 are as follows:

	For the years ended August 31,
$ in thousands	2012		2011		2010
Interest cost	$	325	$	334	$	351
Net amortization and deferral		166		164		178
Total	$	491	$	498	$	529

The estimated actuarial loss for the supplemental retirement plan that will be amortized, on a pre-tax basis, from accumulated other comprehensive loss into net periodic benefit cost during fiscal 2013 will be $212.

The Company’s future annual contributions to the supplemental retirement plan will be equal to expected net benefit payments since the plan is unfunded.The following net benefit payments are expected to be paid:
