ITEM 1.

BUSINESS

Pending Merger With Caterpillar Inc.

On November 14, 2010, we entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Caterpillar Inc., pursuant to which we will become a wholly owned subsidiary of Caterpillar Inc.

In connection with the merger, each outstanding share of our common stock, par value $0.01 per share (other than those held by us, Caterpillar Inc. or any subsidiary of Caterpillar Inc.) and other than those shares with respect to which appraisal rights are properly demanded and not waived, withdrawn or lost, will be converted into the right to receive $92 in cash, without interest.

The completion of the merger is subject to certain conditions, including, among others (i) the absence of certain legal restraints to the consummation of the merger or the other transactions contemplated by the Merger Agreement and (ii) the expiration or termination of the applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and certain other antitrust approvals. On January 20, 2011, our stockholders approved the Merger Agreement.

Terex Mining Acquisition

On February 19, 2010, we completed the acquisition of the mining equipment business (“Terex Mining”) of Terex Corporation for $1.0 billion in cash and 5,809,731 shares of our common stock, subject to certain post-closing net assets, net debt and other adjustments. Terex Mining is a worldwide manufacturer of hydraulic excavators, off-highway haul trucks and drills, which are complementary to our existing product lines. As a result of this acquisition, we have significantly expanded our product portfolio, which allows us to compete in a larger portion of the mining machinery market. We believe that this expanded product portfolio has made us the premier supplier of mining equipment.

Also on February 19, 2010, we entered into an amendment to our existing credit agreement to provide for an additional new secured term loan of $1.0 billion and $167.5 million of additional revolving credit facilities to fund the cash portion of the purchase price for Terex Mining and provide us with new revolving credit facilities to support our future working capital needs and capital expenditure plan.

Terex Mining Acquisition Rationale

We believe that our acquisition of Terex Mining has made us the premier supplier of mining equipment. This acquisition allowed us to (i) expand our global geographic footprint since there was little geographic overlap between our current operations and the operations of Terex Mining; (ii) diversify our product portfolio across a broader range of commodities; (iii) increase our potential surface mining market to approximately $34 billion as of December 31, 2010; and (iv) utilize the services of an expanded team of approximately 10,700 employees and contract employees in nearly 100 locations around the world.

Certain Strategic and Financial Benefits of the Terex Mining Acquisition

Enhanced Scale and Scope. The products acquired in the Terex Mining acquisition consisted of the world’s largest hydraulic excavators, rugged haul trucks, advanced drilling machines and highwall mining systems. As of the acquisition date, Terex Mining had 38 facilities around the world with approximately 2,100 employees. As a result of this acquisition, we have expanded our product offering into the growing hydraulic excavator market, as well as the truck and hydraulic track drill product categories.

Diversified Customer, Commodities and Geographic End Markets. We have benefited from Terex Mining’s strong presence in the Asia Pacific (“APAC”) region. With this acquisition, our sales in the APAC region have increased. We diversified our overall commodity exposure by reducing our percentage of total sales generated by coal-related mining equipment and increased our percentage of total sales generated by iron ore related mining equipment.

Aftermarket Revenue Opportunities. The acquisition of Terex Mining has generated additional aftermarket revenue opportunities. As a result of this acquisition, our installed base of surface mining machinery has grown from approximately $20 billion at December 31, 2009 to approximately $34 billion at December 31, 2010. With a broader product portfolio, we have experienced an increase in opportunities for aftermarket parts and services.

Incremental Access to Growing Economies. The acquisition of Terex Mining has increased our access to growing economies. Our product lines are well positioned in the fast-growing, developing countries of Brazil, Russia, India and China.

Significant Synergy Potential. The acquisition of Terex Mining enhanced our earnings in 2010 and should allow us to benefit from synergies in future years. We expect to be able to realize over $100 million in annual run-rate operating synergies, which we believe may be achievable by the end of 2011. A substantial portion of these synergies are expected to result from the integration of our global manufacturing facilities and leveraging manufacturing centers of excellence, as well as the integration of market distribution, engineering and product development resources. Additional cost savings are expected to be realized through the integration of management functions and reducing purchasing expenses and raw material costs, similar to our successful integration of DBT GmbH following its acquisition in May 2007. We achieved approximately $40 million of synergy savings in 2010 and expect to reach $100 million in total synergies in 2011.

Cultural Similarities. The culture across the mining industry is both universal and unique. The established culture at Terex Mining facilitated the integration process, which was substantially complete as of December 31, 2010.

Company Overview

We are a leading designer and manufacturer of safe and highly productive mining equipment for the extraction of coal, copper, oil sands, iron ore and other minerals in major mining centers throughout the world. In addition to the manufacture of original equipment, we also provide the aftermarket replacement parts and service for this equipment. We operate in two business segments: surface mining (including the principal products of Terex Mining) and underground mining. Substantially all of our products and services are marketed under the

Bucyrus name. We have manufacturing facilities in Australia, China, the Czech Republic, Germany, Mexico, the United Kingdom and the United States, and service and sales centers in Australia, Brazil, Canada, Chile, China, India, Indonesia, Peru, Russia, South Africa, and the United States. The largest markets for our surface mining original equipment and aftermarket parts and service have historically been in Australia, Canada, China, India, South Africa, South America and the United States. We expect these markets to continue to be our largest surface mining equipment markets and we expect growth in the Russian and Asian markets. The largest markets for our underground mining original equipment and aftermarket parts and service have historically been in the United States, Australia and China. We expect these markets to continue to be our largest underground mining equipment markets, and we expect potential growth in the Russian, Eastern European and Indian markets in the next three to five years.

The market for our original equipment is closely correlated with customer expectations of sustained strength in prices of mined commodities. Growth in demand for these commodities is a function of, among other things, economic activity, population increases and continuing improvements in standards of living in many areas of the world. In 2010, the market prices for the primary commodities mined by our equipment (coal, copper, iron ore and oil) increased significantly from the end of 2009.

Our aftermarket parts and service sales tend to be less cyclical than our original equipment sales. Our original equipment is typically kept in continuous operation by our customers for four to 40 years, requiring regular maintenance and repair throughout its productive life. The size of our installed base of surface mining and underground mining original equipment at December 31, 2010 was approximately $34 billion and $10 billion, respectively, based on estimated replacement value. This installed base of original equipment provides the foundation for our future aftermarket sales. Our ability to provide on-time delivery of reliable parts and prompt service are other important drivers of our aftermarket sales.

The mix of our original equipment and aftermarket sales was as follows:


	Year Ended December 31,
	2010			2009			2008
Surface Mining:
Original equipment		50.4	%		41.6	%		48.6	%
Aftermarket parts and service		49.6	%		58.4	%		51.4	%
Underground Mining:
Original equipment		53.8	%		60.1	%		60.3	%
Aftermarket parts and service		46.2	%		39.9	%		39.7	%
Total:
Original equipment		51.6	%		51.1	%		54.3	%
Aftermarket parts and service		48.4	%		48.9	%		45.7	%

A substantial portion of our sales and operating earnings is attributable to our operations located outside the United States. We generally sell our original equipment, including that sold directly to foreign customers, and most of our aftermarket parts in either United States dollars or euros. A portion of our aftermarket parts sales is denominated in the currency of the country in which our products are sold. Aftermarket services are paid for primarily in local currency, which is naturally hedged by our payment of local labor in local currency.

We incorporated in Delaware in 1927 as the successor to a business that began producing excavation machines in 1880.

Our Industry

The surface mining equipment that we manufacture and service is used primarily in coal, copper, oil sands, iron ore, gold and other mineral mines worldwide. The underground mining equipment that we manufacture and service is used primarily in coal mines worldwide. Growth in demand for these commodities is generally a function of population growth and continuing improvements in standards of living in many areas of the world. The market for original equipment tends to be somewhat cyclical in nature due to market fluctuations for these commodities; however, the aftermarket for parts and services is generally more stable because this expensive, complex equipment is typically kept in continuous operation for four to 40 years and requires regular maintenance and repair throughout its productive life.

We are one of the leading suppliers of surface and underground mining equipment and we believe that with the acquisition of Terex Mining, we are the premier supplier of mining equipment. In addition, in various product lines several niche players compete. Our original equipment is primarily used by large multinational companies engaged in mining for a variety of commodities. We believe that recent consolidation within the mining industry has resulted in larger, well-capitalized companies being better positioned to withstand commodity price cycles.

Commodity Markets

Coal. Coal is the world’s most abundant low-cost energy source and is a critical source of energy for many countries. There are two primary types of coal: steam or thermal coal, which is used to generate electricity, and coking or metallurgical coal, which is required to produce steel. Coal provides approximately 27% of global primary energy needs and generates approximately 41% of the world’s electricity. It has been estimated that there are over 847 billion tonnes of proven coal reserves worldwide, which means that there is enough coal to last approximately 119 years at current rates of production. Coal reserves are available in almost every country worldwide, with recoverable reserves in as many as 70 countries. The largest reserves are in the United States, Russia, China and India. The largest coal producing nations in 2009 were China, the United States, India, Australia, Indonesia, South Africa, Russia, Kazakhstan, Poland and Columbia according to the World Coal Association. We believe that large amounts of coal reserves, the relative price of coal and significant coal infrastructure make transitions from coal to other energy sources more difficult and financially challenging. Additionally, new clean coal technologies, flue gas desulphurization and carbon capture and storage help to mitigate environmental and regulatory concerns, and new technologies, such as gasification and liquefaction, create opportunities for future growth in the use of coal.

According to the International Energy Outlook by the United States Energy Information Administration, 75 percent of the increase in world coal production is expected to be attributable to China, with output expected to rise by 54.7 quadrillion Btu from 2007 through 2035. This outlook is based on the assumption that much of the demand for coal in China will continue to be met by domestic production. Other expected increases in regional coal production from 2007 through 2035 include 7.1 quadrillion Btu in Australia/New Zealand (representing 10 percent of the increase in world coal production), 4.0 quadrillion Btu in non-OECD Asia (excluding China), 3.0 quadrillion Btu in Africa, 2.8 quadrillion Btu in the United States and 2.4 quadrillion Btu in Central and South America.

Copper. Copper is a basic material used in residential and commercial construction, electrical equipment, transportation, industrial machinery and durable consumer goods. Demand for copper is driven by accelerating economic growth in the developing world and continued consumption in the developed world. According to the International Copper Study Group, worldwide mine production of copper was 15.9 million tons in 2009 and was projected to increase to 16.2 million tons in 2010 and 17.1 million tons in 2011.

Oil Sands. Oil sands are a viscous mixture of sand, bitumen, clay and water with the consistency of cold molasses. According to the Energy Resources Conservation Board, an independent quasi-judicial agency of the Government of Alberta, the oil sands in the Athabasca region of northern Alberta, Canada is believed to contain the second largest petroleum reserves in the world, second only to Saudi Arabia. Approximately 27.6 billion cubic meters (175 billion barrels) of bitumen are locked in these oil sands. Currently, industry extracts approximately 174,800 cubic meters (1.1 million barrels) of bitumen each day, a rate expected to rise to 429,000 cubic meters (2.7 million barrels) by 2015.

Iron Ore. Iron ore is one of the only sources of primary iron used to make steel and is mined in more than 50 countries. The seven largest iron ore producing countries account for approximately three-quarters of total global production. Australia and Brazil together account for approximately one-third of total exports. The market for iron ore is largely a function of the demand for steel. Worldwide production of iron ore in 2009 was 1.7 billion tons, was estimated to be 1.8 billion tons in 2010 and is forecasted to increase to 1.9 billion tons in 2011.

Other Minerals. We have also been successful in selling our equipment for use in the mining of various other minerals including gold, uranium, diamonds, molybdenum, phosphate, bauxite, potash and trona.

Surface Mining Segment

Overview

We design, manufacture and market draglines, electric mining shovels, hydraulic excavators, off-highway haul trucks, rotary blasthole drills, hydraulic track drills and highwall miners used for surface mining and provide the aftermarket replacement parts and service for these machines. Based on the assessment of original equipment estimated replacement value, we believe that we have the largest installed base of this original equipment in the world and are the leading market provider of draglines, large rotary blasthole drills and highwall miners. Our products are sold to customers throughout the world in nearly every market where surface mining is conducted with modern methods. Our products are continuously evolving as improvements in design and technology emerge, with the goal of providing our customers maximum productivity and cost effectiveness. We concentrate on producing technologically advanced machines that enable our customers to conduct cost-efficient operations. We utilize alternating current (“AC”) drive technology for draglines, electric mining shovels and off-highway haul trucks and offer advanced computer control systems which allow technicians at our headquarters to remotely monitor and adjust the operating parameters of suitably equipped machines.

Growth in the surface mining industry is driven by increased demand for surface mined commodities such as copper (especially in South America), oil sands (Canada), iron ore (China, Brazil and Australia) and coal (China, the United States, India, Australia, South Africa and Russia). We believe that the potential for increased surface mining of coal in China and India is promising.

Original equipment sales are closely correlated with the strength of commodity markets and maintain and augment our installed base of surface mining original equipment of approximately $34 billion, based on estimated replacement value, at December 31, 2010. Our installed base of original equipment provides the foundation for our surface mining aftermarket activities. Our aftermarket parts and service operations, which historically have been more stable and more profitable than our original equipment sales, have accounted for approximately 59% of our total sales over the last 10 years. Over that period and throughout various commodities cycles, our aftermarket sales have sustained a compound annual sales growth rate of 20.3% through December 31, 2010. Without the Terex Mining acquisition in 2010, the 10-year compound annual sales growth rate through December 31, 2010 was 13.3%. We have established a global presence with a network of sales and service centers located in all countries where major surface mining operations are located. We manufacture our original equipment and the majority of our aftermarket parts at our facilities in the United States, Germany, Mexico, the United Kingdom and Australia.

Original Equipment

Our surface mining original equipment includes draglines, electric mining shovels, hydraulic excavators, drills, off-highway haul trucks and highwall miners.

Draglines. Draglines are primarily used in coal mining applications to remove overburden (i.e., the rock and soil that lies above the coal being mined) by dragging a large bucket through the overburden and carrying it away. Our primary draglines weigh from 1,900 to 8,400 tons and are typically described in terms of their “bucket size,” which typically range from 31 to 152 cubic yards. Our primary models range in price from approximately $65 million to $200 million per dragline for turnkey installations. Draglines are the largest and most expensive type of surface mining equipment but offer customers the lowest cost per ton of material moved. The average life of our draglines is approximately 40 years.

Electric Mining Shovels. Mining shovels are primarily used to load copper, coal, oil sands, iron ore, and other mineral bearing materials, overburden or rock into trucks. There are two basic types of mining shovels: electric and hydraulic. Electric mining shovels are able to handle a larger load, allowing them to move greater volumes of rock and minerals, while hydraulic shovels are diesel powered, generally smaller and more maneuverable. An electric mining shovel typically offers significantly lower cost per ton of mineral mined over a longer period of time as compared to a hydraulic shovel. Electric mining shovels are characterized in terms of hoisting capability and dipper or load capacity. We offer a full line of electric mining shovels, with available hoisting capability of up to 120 tons. Dipper capacities range from nine to 80 cubic yards and prices range from approximately $5 million to $25 million per shovel, with the selling price of our most popular shovels being in the upper part of this range. Our electric mining shovels have an average life of approximately 15 years.

In 2010, we introduced the 495HR² and 495HF² shovels that incorporate our newly designed operator’s cab featuring a state of the art operator’s control station and fully outfitted amenity area with built in cabinets, robust refrigerator and temperature controlled HVAC systems. The highlights of this series include an insulated gate bipolar transistor (“IGBT”) drive system with AC motors, planetary gear configuration and a third rail swing system to enhance shovel operation through increased efficiency and lower maintenance costs. A fully modularized electrical room ships directly to the field to facilitate the field assembly process.

Hydraulic Excavators. Hydraulic excavators in shovel or backhoe configuration are primarily used to dig overburden and minerals and load the material into trucks. These excavators are utilized in surface mines, quarries and large construction sites around the world. Our range of hydraulic excavators begins in the 100 ton size class and reaches up to a 1,000 ton size. Our hydraulic excavators feature patented TriPower technology for increased digging forces and greater productivity. In particular, our 1,000 ton RH 400 is the world’s largest hydraulic excavator and is capable of carrying up to 90 tons. Prices range from approximately $0.9 million to $15 million per excavator. Our hydraulic excavators have an average life of approximately seven to 15 years.

Drills. Many surface mines require breakage of rock, overburden or ore by blasting with explosives. To accomplish this, it is necessary to bore out a pattern of holes in the ground area to be mined into which explosives are then placed. Drills are used to drill these holes and are usually described in terms of the diameter of the hole they bore. We offer a line of rotary blasthole drills ranging in hole diameter size from 6.0 inches to 17.5 inches and ranging in price from approximately $0.6 million to $6 million per drill, depending on machine size and other variable features. The selling price of our most popular rotary blasthole drills is in the upper part of this range. Our rotary blasthole drills have an average life of approximately 10 to 15 years.

Modular design techniques have been applied to our rotary blasthole drills (excluding the drill product line acquired through the acquisition of Terex Mining) to provide ease of maintenance by simplifying equipment change outs and servicing. Our 49HD drill has the production capabilities of larger machines and the flexibility, speed and maneuverability of smaller machines.

We also offer a wide selection of hydraulic track drills that range in hole diameter size from 2.5 inches to six inches for quarrying, construction and utility applications. Our exclusive hydraulic system provides faster operation and reduced fuel usage. Prices average $0.5 million per drill. Our hydraulic track drills have an average life of approximately seven to 10 years.

Off-Highway Haul Trucks. Our truck business consists of a series of rear dump trucks ranging in size from 150 tons to 400 tons. High capacity surface mining trucks are off-road dump trucks. They are powered by a diesel engine driving an electric alternator that provides power to individual electric motors in each of the rear wheels. Our trucks are engineered to minimize the cost of ownership for the customer. Prices can be up to $6 million per truck. Our trucks have an average life of approximately eight to 10 years.

Highwall Miners. Our highwall mining equipment is used for cost effective mining of residual coal seams from the surface. This equipment is comprised of a self-contained coal mining system that remotely mines underground coal from the surface of a surface mining operation to predetermined depths. Prices range up to $8 million per unit.

Aftermarket Parts and Services

We have a comprehensive aftermarket business that supplies replacement and upgrade parts and services for our installed base of original equipment. Customer purchases of

aftermarket parts and services over the life of certain of our original equipment can exceed the initial purchase price of the original equipment. Our aftermarket offerings include engineered replacement parts, maintenance and repair labor, technical advice, refurbishment and relocation of machines, comprehensive structural and mechanical engineering, non-destructive testing, repairs and rebuilds of machine components, product and component upgrades, turnkey assembly and equipment operation. We also distribute less sophisticated components that are consumed in the normal course of machine operation. A substantial portion of our international repair and maintenance services are provided through our global network of wholly owned foreign subsidiaries and overseas offices operating in Australia, Brazil, Canada, Chile, China, India, Indonesia, Mexico, Peru and South Africa.

We generally realize higher gross margins on sales of aftermarket parts than on sales of original equipment. Moreover, because our original equipment tends to operate continuously in all market conditions with expected lives ranging from approximately seven to 40 years and have predictable parts and maintenance needs, our aftermarket business has historically been more stable and predictable than the market for our original equipment, which is closely correlated with expectations of sustained strength in commodity markets.

In certain applications, we offer comprehensive maintenance and repair contracts. Under these contracts, we provide all replacement parts, regular maintenance services and necessary repairs for the excavation equipment at a particular mine with an on-site support team. In addition, some of these contracts call for our personnel to operate the equipment being serviced. Maintenance and repair contracts typically have terms of three to five years with provisions for renewal and early termination.

Our aftermarket parts and service sales have generally grown consistently over the past 10 years. For most of our customers, mining continues even during periods of lower commodity prices, maintaining demand for aftermarket parts and services, although competition from independent firms called “will-fitters” that produce copies of the parts manufactured by us and other original equipment manufacturers tends to intensify during periods of commodity price weakness. We continue to try to improve our performance in key areas such as quality, reducing lead times, increasing on-time delivery and maintaining an information technology infrastructure that motivate customers to purchase their aftermarket parts and services from us. We believe our emphasis on quality and technology has further increased customer motivation to use more of our aftermarket parts and services. We believe that our continued focus on on-time delivery, competitive lead times and enhanced information technology systems combined with our comprehensive offerings of quality aftermarket components and installation services and our development of key supplier alliances position us to compete effectively for most aftermarket opportunities.

Aftermarket sales accounted for approximately 50%, 58% and 51% of our surface mining sales for the years ended December 31, 2010, 2009 and 2008, respectively.

Customers

Most of our customers are large multinational corporations with operations in the various major surface mining markets throughout the world and state owned enterprises. In recent years, customers have reduced their operating costs by employing larger, more efficient machines such as those we produce and have become increasingly sophisticated in their use and understanding of technology. Our focus on incorporating advanced technology such as AC drives and advanced controls has increased customer adoption of our product offerings.

Further, we believe that these developments have contributed to increased demand for our aftermarket parts and services since we are well-equipped to provide the more sophisticated parts, product technical knowledge and service required by customers who use more complex and efficient machines.

Over the past five years, our surface mining customers have conducted their most significant operations in South America, the United States, Canada, Australia, India and China. We expect China and India to experience the most growth in surface mining in the future. In the aggregate, sales of our surface mining original equipment were $1.2 billion, $534.5 million, and $622.9 million for the years ended December 31, 2010, 2009 and 2008, respectively, and sales of our surface mining aftermarket parts and services were $1.2 billion, $750.5 million and $659.6 million for the years ended December 31, 2010, 2009 and 2008, respectively. Our customers purchase our aftermarket parts and services because they are high quality, reliable and durable products, and our services are well suited to the long productive lives of our original equipment.

Our customers operate under a high fixed cost structure. Small savings on the initial purchase of original equipment may be offset by less efficient operations and greater down time. Furthermore, our customers’ operations are often conducted in remote areas and the large capital investment and long lead time associated with the purchase and erection of a machine encourages many customers to select more reliable and efficient machines and to keep these machines in continuous operation for as long as possible. As a result, our customers are focused on quality as well as price and expect us to offer comprehensive aftermarket parts and services to increase their efficiency and reduce downtime.

We do not consider ourselves to be dependent upon any single customer, although on an annual basis a single customer may account for a meaningful percentage of our sales, particularly original equipment sales. Our top five customers in each of the years ended December 31, 2010, 2009 and 2008 collectively accounted for approximately 27%, 50%, and 43% respectively, of our total surface mining sales. We believe these relatively high percentages reflect the recent consolidation within the mining industry.

Competitors

Our electric mining shovels and draglines compete with similar products manufactured by one significant competitor. For certain applications, our small electric mining shovels also compete against the biggest hydraulic excavators made by several worldwide manufacturers and local and regional competitors, including quasi-governmental competitors. In hydraulic excavators, drills and off-highway haul trucks, we compete with several worldwide manufacturers. In China, India and Russia, we face competition from regional and domestic equipment manufacturers across our product portfolio. Competition factors are diverse and include price, lead times, operating costs, machine productivity, technological enhancements, design and performance, reliability, service, delivery and other commercial factors, as well as government mandates to purchase their mining equipment from local suppliers. Long standing customer relationships are very important to us as well as our competition. These relationships can provide a strong incumbency advantage in retaining business and securing new orders.

than components we manufacture. We also face significant competition from manufacturers and distributors in the sale of consumable replacement parts which we do not manufacture, including wire rope, non-specialized parts and electrical parts, as well as aftermarket services competition from these market participants and local machining and repair shops.

We have a variety of programs to attract large volume customers for our replacement parts. Although will-fitters engage in significant price competition in parts sales, we believe that we possess non-price advantages over will-fitters. We believe that our engineering and manufacturing technology and marketing expertise exceed that of our will-fit competitors, who in many cases are unable to duplicate the exact specifications of our replacement parts. Moreover, the use of replacement parts not manufactured by us can void the warranty on a piece of original equipment, which generally runs for one year, with certain components under warranty for longer periods.

In recent years, we have received several large orders for the refurbishment and relocation of machines, especially draglines.

Underground Mining Segment

Overview

We design, manufacture and market complete system solutions for underground coal mining worldwide. We are one of the world market leaders in longwall mining equipment, which is the result of comprehensive experience and know-how gained over decades of innovative, high-performance engineering. Original equipment sales are closely correlated with the strength of commodity markets and maintain and augment our underground mining original equipment installed based of approximately $10 billion, based on estimated replacement value, at December 31, 2010. This installed base provides the foundation for our aftermarket activities. We have established a global presence with a network of sales and service centers located in all countries where major underground mining operations are located. Our original equipment and aftermarket parts are manufactured in Germany, the United States and, to a lesser extent, in China, Australia and the Czech Republic.

The two main methods of underground mining are longwall and room and pillar mining, which differ significantly in their initial investment amount and corresponding output.

Longwall Mining

Longwall mining involves the near complete extraction of hard coal or other minerals contained in a large rectangular block, or “panel,” using mechanical shearers or plows, after which the mined-out area is allowed to collapse. Room and pillar mining equipment is used to develop a panel by excavating passageways along the panel perimeter. Working under the steel canopies of movable hydraulic roof supports, a coal cutting machine, such as a shearer or a plow, runs back and forth along the “face,” or the exposed part of the panel, taking a cut during each pass. As the shearer or plow cuts into the coal or mineral and deposits it onto the conveyor system, self-advancing hydraulic roof supports temporarily hold up the roof. As the shearer or plow proceeds through the coal or mineral, the equipment, if automated, signals the roof supports to hydraulically drive the entire longwall system forward while the roof behind the roof supports is allowed to collapse.

The longwall method is chosen if the geological conditions of the coal or other mineral deposit are favorable (i.e., the coal or mineral seams are vast in length and width and with minimal rock intrusions, permitting several large panels to be prepared) or generally if the coal or other mineral deposits are more than 1,000 feet underground. A complete longwall mining system typically requires an initial mining equipment investment of between approximately $25 million and $60 million, and a single longwall operating unit can generate an annual output of between approximately four and eight million tons. In certain applications, annual output can be two to three times this volume.

Room and Pillar Mining

In room and pillar mining, hard coal or other mineral deposits such as potash are mined by cutting a network of “rooms” into the coal or mineral seam, leaving behind “pillars” of coal or other mineral to support the roof of the mine either temporarily or permanently. This mining method also requires several pieces of equipment that work together in a synchronized fashion; however, they are not mechanically connected to each other as in longwall mining. The process begins with the continuous miners cutting the coal or other mineral and conveying it through the machine’s conveyor. The coal or mineral is then discharged from the back of the continuous miner into haulage vehicles or mobile chain conveyors which transport it to a feeder (or feeder breaker if the material needs to be crushed or down-sized). The coal or mineral is then loaded on to a belt system, which takes the coal or mineral to the surface. As the continuous miner advances into the coal or mineral deposit, a roof bolter drills and installs roof bolts to secure the roof of the mine.

The pillars can equal to up to 50% of the total coal or mineral in the seam, although this coal or mineral can sometimes be recovered at a later stage, depending on geological conditions. Where this is viable, pillars are partially mined through by the continuous miner as mining retreats back towards the main entries. The room and pillar mining method is used if the coal or mineral deposit requires the mine operator to remove the coal or mineral in smaller and shallow panels. The required initial investment in equipment for one room and pillar mining segment is typically approximately $8 million and the corresponding average annual production is approximately 0.4 million tons.

Original Equipment

Our underground mining original equipment includes longwall equipment and room and pillar equipment.

Longwall Equipment. We are one of the world’s top producers of longwall mining equipment. Our longwall equipment includes hydraulic roof supports and electro-hydraulic controls, automated plow systems, shearers and armored face conveyors, including entry conveyors with a built-in crusher. Our systems can be customized to suit a wide range of mining conditions anywhere in the world, thereby ensuring an appropriate combination of safety, operational reliability and productivity at competitive prices.

Hydraulic Roof Supports. Roof supports provide support to the mine roof during longwall mining. The supports advance with the longwall shearer or plow, allowing mine operators to safely control roof falls as the panel is mined. We offer a full range of roof supports suitable for various mining heights (typically from 0.6 meters to 7.5 meters), including Longwall Top Coal Caving (“LTCC”) roof supports that allow for recovery of some coal seams that exceed 7.5 meters and support capacities in excess of 1,200 tons per shield. We also

offer electro-hydraulic roof support systems for automatic sequences or manually operated functions. A complete roof support system typically includes from 50 to 225 roof support shields. Prices range from approximately $15 million to $50 million per roof support system. Our roof supports have an average minimum life of approximately nine to 12 years.

Armored Face Conveyors. Armored face conveyors (“AFCs”) are used in longwall mining to transport material cut by the shearer or plow away from the longwall face. AFCs are armored steel pan conveyors that are used to convey mined material both in the longwall face and out of the longwall face. Our AFC systems are designed for a variety of performance requirements in low, medium and high seams and for short and long faces. We exclusively offer the Controlled Start Transmission (“CST”) drive systems for long high-capacity faces, which allows for variable start speeds and precise load sharing to reduce chain breaks. Prices range from approximately $4 million to $12 million per AFC system. Our AFC systems are generally purchased in pairs and the pair has an average life of approximately six to nine years.

Longwall Shearers. A longwall shearer moves parallel to the coal or mineral face, cutting into the coal as it moves backward and forward across the face, depositing the coal onto the conveyor system. The shearer is usually a double ended machine with ranging arms at each end and cutter drums mounted on each ranging arm, so the shearer can cut in either direction. We offer a wide range of shearers for low, medium and high seams, currently from 1.8 meters up to 7.0 meters, with production rates of up to 5,000 tons per hour. Prices range from approximately $2.5 million to $3.5 million per shearer. Our shearers are generally purchased in pairs and the pair has an average life of approximately six to eight years.

Automated Plow Systems. Fully automated plow systems are a safe and economically attractive method of mining low and medium coal seam heights. Our plows have high extraction and loading rates in seams of 0.6 meters to 2.3 meters resulting in mining rates of up to 3,500 tons/hour. Prices range from approximately $30 million to $50 million per automated plow system including roof supports. Our automated plow systems have an average life of approximately four to 10 years.

Room and Pillar Equipment. In addition to longwall mining equipment, we offer an extensive line of technologically advanced room and pillar equipment. Our room and pillar equipment offerings include continuous miners, feeder breakers, battery- and diesel-powered underground utility vehicles, continuous haulage systems, roof bolters and belt systems. Our continuous miners can be used for both soft- and hard-cutting applications. In recent years, we extensively re-engineered our room and pillar product portfolio, particularly upgrades to the continuous miner product line.

Continuous Miners. Continuous miners are electric, self-propelled machines that constantly cut material and simultaneously load that material onto an internal conveyor. We offer a “seamless” family of continuous miners for both soft and hard cutting applications for seams from 0.8 meters to 5.2 meters. Due to the severity of the operating environment and continuous usage, these products require extensive aftermarket parts, service and maintenance. Prices range from approximately $1.6 million to $5 million per continuous miner. Our continuous miners have an average life of approximately 8 to 12 years.

Continuous Haulage Systems. The continuous haulage system is used to efficiently remove cut coal or other mineral from the working face to the main mine belts on a continuous basis. The system is usually attached to the continuous miner or independently trammed behind the miner. Our systems can be implemented in new or existing operations with capacity

of up to 38 tons per minute. Prices range from approximately $1.4 million to $4 million per continuous haulage system. Our continuous haulage systems have an average life of approximately 10 to 15 years.

Feeder Breakers. Feeder breakers are a crushing unit that breaks the coal or other mineral into a smaller size suitable for transportation by the belt conveyor systems or feeding into process facilities. Our underground feeder breakers have a production capacity of up to 1,800 tons per hour with a pick force of up to 45,400 kilograms. The units are custom designed to allow maximum discharge rates from the mobile haulers. Prices range from approximately $0.3 million to $0.8 million per feeder breaker. Our feeder breakers have an average life of approximately 10 to 20 years.

Underground Haulage and Utility Vehicles. Underground haulage vehicles are vehicles used to transport material from continuous miners to the main mine belt where the haulage vehicle has self-contained discharge capability to unload material onto the belt. We offer both battery-powered and diesel-powered haulage vehicles. Underground utility vehicles are self-loading vehicles used to clean roadways, haul supplies and perform other functions. Prices range from approximately $0.3 million to $1 million per underground utility haulage vehicle or underground utility vehicle, and each has an average life of approximately 10 to 15 years.

Along with our two main product groups, we offer solutions in the field of horizontal crushing equipment for coal and non-coal applications such as aggregates typically used in road construction, potash and rock salt. The product range includes size reduction technology for primary crushing and scraper chain conveyors.

Aftermarket Parts and Services

We have a comprehensive aftermarket business that supplies replacement and upgrade parts and services for our installed base of original equipment. Our aftermarket offerings include replacement parts and a complete range of services including on-site services, repairs and overhauls. In addition, we provide consulting services, such as mine planning, in emerging markets. We support our customers through the entire equipment life cycle and re-use the information gathered in this process to further improve equipment productivity as well as to develop new technology and systems, tailored to meet customer needs.

We generally realize higher margins on sales of aftermarket parts than on sales of original equipment. Moreover, because our original equipment tends to operate continuously in all market conditions with expected lives ranging from approximately four to 15 years and has predictable parts and maintenance needs, our aftermarket business has historically been more stable and predictable than the market for our original equipment, which is closely correlated with expectations of sustained strength in commodity markets.

Aftermarket sales accounted for approximately 46%, 40% and 40% of our underground mining sales for the years ended December 31, 2010, 2009 and 2008, respectively.

Customers

Multinational coal mining corporations make up the majority of our customer base. In recent years, our large and efficient machines have enabled our customers to reduce their operating costs while enhancing their sophistication for the use and understanding of the employed technology.

Over the past five years, our customers have conducted their most significant operations in the United States, China, South Africa, Australia, Eastern Europe and Western Europe. In the aggregate, sales of our underground mining original equipment were $680.5 million, $821.0 million and $737.6 million for the years ended December 31, 2010, 2009 and 2008, respectively, and sales of our aftermarket parts and services were $584.6 million, $545.8 million, and $487.9 million for the years ended December 31, 2010, 2009 and 2008, respectively.

We do not consider ourselves to be dependent upon any single customer, although on an annual basis a single customer may account for a meaningful percentage of our sales, particularly original equipment sales. Our top five customers in each of the years ended December 31, 2010, 2009 and 2008 collectively accounted for approximately 29%, 41% and 43%, respectively, of our total underground mining sales. We believe this relatively high percentage reflects the recent consolidation within the mining industry.

Competitors

Our complete system solutions to the underground mining industry compete with similar products manufactured by one significant competitor. We are now facing increased competition from manufacturers based in low cost regions such as China, Russia, India and Poland. For example, in China there is significant pressure to increase domestic purchases for roof supports and to reduce the cost of roof supports which are imported. To better compete in these low-cost regions, we have two manufacturing facilities and a joint venture with a local partner in China, and we may consider further expansion in the future. Our other original equipment competitors in other parts of the world are small, regional manufacturers that typically serve the regions where they are located. Competition factors are diverse and include price, lead times, operating costs, machine productivity, technological enhancements, design and performance, reliability, service, delivery and other commercial factors, as well as government mandates to purchase their mining equipment from local suppliers. Long standing customer relationships are very important to us as well as our competition. These relationships can provide a strong incumbency advantage in retaining business and securing new orders.

For most owners of our machines, we are the primary replacement source for highly engineered, integral components. Competition in replacement parts sales consists primarily of will-fitters. Copies of our components that are manufactured by others are generally sold at lower prices for use on older machines and are generally acknowledged to be of lower quality than components we manufacture. We also face significant competition from manufacturers and distributors in the sale of consumable replacement parts which we do not manufacture, including non-specialized parts and electrical parts, as well as aftermarket services competition from these market participants and local machining and repair shops.

manufacturing technology and marketing expertise exceed that of our will-fit competitors, who in many cases are unable to duplicate the exact specifications of our replacement parts. Moreover, the use of replacement parts not manufactured by us can void the warranty on a piece of original equipment, which generally runs for one year, with certain components under warranty for longer periods.

General

Marketing, Distribution and Sales

Our original equipment and aftermarket parts and services are sold directly by our personnel in the United States and in foreign markets as well as by independent dealership networks and joint venture partners. Sales outside the United States are made through our sales offices located in Australia, Brazil, Canada, Chile, China, France, Germany, India, Indonesia, Lebanon, Mongolia, the Netherlands, Peru, Poland, Russia, South Africa, Ukraine and, in some markets, by our independent sales representatives. We typically require a down payment when an agreement is reached for a new machine and customers generally then make progress payments throughout the construction of the machine. Lead times for our large surface mining machines generally vary from two to nine months, but a dragline’s lead time can be more than two years. Lead times for our large underground mining machines generally approximate nine months, but a roof support system’s lead time may be 12 months. In addition, our long lead time replacement part sales often call for prices in effect at the time of order.

International Operations

We have manufacturing facilities in Australia, China, the Czech Republic, Germany, Mexico, the United Kingdom and the United States and service and sales centers in Australia, Brazil, Canada, Chile, China, India, Indonesia, Peru, Russia, South Africa and the United States. Additionally, we employ direct marketing strategies in these markets as well as developing markets such as Jordan, Mauritania and Turkey. A substantial portion of our sales and operating earnings is attributable to operations located outside the United States.

Original equipment sales in foreign markets are supported by our network of foreign subsidiaries and overseas offices, as well as by independent dealership networks and joint venture partners that directly market our products and provide ongoing services and replacement parts for original equipment installed abroad. We believe that the availability and convenience of the services provided through our network ensure the efficient operation of our original equipment by our customers, promote higher gross margin aftermarket sales of parts and services, and provide us with a local presence to promote original equipment orders.

We sell most of our original equipment, including sales directly to foreign customers, in either United States dollars or euros. We sell most of our aftermarket parts in United States dollars and euros, with limited aftermarket parts sales denominated in the currency of the country in which our products are sold. Both surface mining and underground mining aftermarket services are paid primarily in local currency, with a natural partial currency hedge through payment for local labor in local currency. The value, in United States dollars, of our investments in our foreign subsidiaries and of dividends paid to us by those subsidiaries will be affected by changes in exchange rates. We enter into currency hedges to help mitigate currency exchange risks.

Raw Materials and Supplies

We purchase from outside suppliers raw materials, principally structural steel, castings and forgings required for our manufacturing operations, and other items, such as electrical equipment and, for our underground mining business, roof support components, that are incorporated directly our end products. Our foreign subsidiaries purchase components and manufacturing services both from local suppliers and from our manufacturing locations around the world. Certain additional components are sometimes purchased from suppliers, either to expedite delivery schedules in times of high demand or to reduce costs. Moreover, in countries where local content requirements exist, local subcontractors can occasionally be used to manufacture the required components.

Manufacturing

The design, engineering and manufacturing of most of our surface mining original equipment and manufactured aftermarket parts is done in the United States, Germany, Mexico, the United Kingdom and Australia. The manufacturing of our underground mining original equipment and manufactured aftermarket parts is done primarily in Germany and the United States and, to a lesser extent, China, Australia and the Czech Republic. Most longwall mining equipment is manufactured in Germany and most of our room and pillar equipment is manufactured in the United States. In addition, all of our underground mining product lines are supported with sourcing and manufacturing capabilities in China.

Customers

We do not consider ourselves dependent upon any single customer, although on an annual basis, a single customer may account for a meaningful percentage of our sales, particularly original equipment sales. For the year ended December 31, 2010, no one customer accounted for more than 10% of our consolidated sales. For the year ended December 31, 2009, one customer, BHP Billiton, accounted for approximately 14% of our consolidated sales. For the year ended December 31, 2008, no one customer accounted for more than 10% of our consolidated sales.

Backlog

Backlog represents unfilled orders for our products and services. Due to the high cost of some of our original equipment, our backlog is subject to volatility, particularly over relatively short periods of time. A portion of our backlog is related to multi-year contracts that will generate revenue in future years. Our backlog at December 31, 2010 and December 31, 2009, as well as the portion of our backlog which was expected to be recognized within 12 months of these dates, was as follows:


	December 31,
	2010		2009		% Change
	(Dollars in thousands)
Surface Mining:
Total	$	1,708,877	$	1,062,977		60.8	%
Next 12 months	$	1,134,105	$	641,599		76.8	%
Underground Mining:
Total	$	997,388	$	816,543		22.1	%
Next 12 months	$	752,424	$	616,784		22.0	%
Total:
Total	$	2,706,265	$	1,879,520		44.0	%
Next 12 months	$	1,886,529	$	1,258,383		49.9	%

Included in surface mining total and next 12 months backlogs at December 31, 2010 were $698.3 million and $500.2 million, respectively, for Terex Mining.

Patents, Licenses and Franchises

We have numerous United States and foreign patents, patent applications and patent licensing agreements. We do not consider our business to be materially dependent upon any patent, patent application, patent license agreement or group thereof.

Research and Development

Our expenditures for design and development of new products and improvements of existing mining machinery products, including overhead, for the years ended December 31, 2010, 2009 and 2008 totaled $62.5 million, $41.9 million and $36.6 million, respectively. The increase in 2010 was primarily due to the acquisition of Terex Mining as well as further development of our electric mining shovels and draglines. The increase in 2009 was primarily due to product enhancements in all of our product lines.

Employees

At December 31, 2010, we employed approximately 9,800 persons, approximately 6,300 of whom are located outside the United States. At December 31, 2010, approximately 1,000 of our United States employees were unionized and approximately 2,400 of our non-United States employees were unionized. We consider our relationship with our unionized and non-unionized workers to be good. In the United States, our five and one-half year contract with the United Steelworkers of America representing hourly workers at our South Milwaukee, Wisconsin facility expires in April 2013, our three-year contract with the United Steelworkers representing hourly workers at our Pulaski, Virginia facility expires in August 2011 and our five-year contract with the United Steelworkers at our Denison, Texas facility expires in May 2015. Also, one of our subsidiaries is a party to a contract with the United Mine Workers of America and the Association of Bituminous Contractors under which its employees’ employment is governed only if they are working at locations that are operated by the United Mine Workers.

Outside of the United States, all of our employees in Germany are covered by an unlimited contract with Manteltarifvertrag der IG Metall or a trade union agreement with IG Metall (Bezirksleitung Nordrhein-Westfalen), which are equivalent to union agreements in the United

States. Also, our three-year and two-year contracts with the Australian Manufacturers Workers Union representing certain of our hourly workers in Australia expire in July 2013 and March 2012, respectively, our three year contract with the Sindicato de Trabajadores Bucyrus Chile Ltda union representing certain of our hourly workers in Chile expires in 2011, and our one-year contract with Základní odborová organizace Bucyrus Czech Republic, a.s. representing certain of our hourly workers in the Czech Republic expired in December 2010. Agreement on a new one-year contract in the Czech Republic was reached in early 2011.

Regulations Affecting Our Customer Base

Our customers are engaged in long-term, capital intensive extractive operations subject to and affected by a variety of environmental, safety, land-use and other regulations. In the United States, federal, state and local authorities regulate mining activities with respect to aspects such as permitting and licensing, air quality, employee safety and health, water pollution, protection of plants and wildlife and land reclamation and restoration. Mining operations may not commence or continue absent federal, state and local government approvals. Approvals may be contingent upon production of extensive social and impact assessments and mitigation measures.

Extractive enterprises in foreign jurisdictions are subject to extensive local regulation. Most key mining jurisdictions subject extractive enterprises to permitting and permit renewal requirements and to royalty assessments. Several key nations place restrictions or assessments on foreign investment. Foreign mining operations may also be subject to safety and environmental regulations that can delay extractive projects or increase associated costs.

Our customers’ operations may also be adversely affected by regulatory regimes concerning mined commodities. In particular, regulations affecting fossil fuel emissions, most notably coal combustion emissions, have had a significant impact on the domestic coal industry. Regulatory initiatives targeting carbon dioxide and other greenhouse gas emissions, which are by-products of coal consumption, could potentially depress coal consumption in the United States and other developed nations. The United States and over 160 other nations are signatories to the 1992 United Nations Framework Convention on Climate Change, which is intended to limit emissions of greenhouse gases, such as carbon dioxide. In December 1997, in Kyoto, Japan, the signatories to the convention established a binding set of emission targets for developed nations which require national reductions in greenhouse gas emissions (the “Kyoto Protocol”). At the December 2007 United Nations Climate Change Conference held in Bali, Indonesia, 187 nations agreed to commence a two-year process on a successor pact to the Kyoto Protocol which expires in 2012. The 2009 United Nations Climate Change Conference was held in Copenhagen, Denmark, with the goal of agreeing on a treaty replacing the Kyoto Protocol. Whether through international treaty, national legislation or state and regional programs to stabilize or reduce greenhouse gas emissions, these restrictions could adversely impact the price of, and demand for, coal in the United States and elsewhere. This in turn could reduce demand for our coal-mining customers’ output and thus their demand for our products, which could have a material adverse effect on our business. No replacement for the Kyoto Protocol was adopted at the 2009 meeting; however, the countries have entered into a letter of intent and will further discuss the objectives for a new treaty at its 2010 meeting in Mexico.

If demand for mining services or mining equipment utilization rates decrease significantly, then demand for our products and services (particularly demand for original equipment, which tends to be closely correlated with the strength of commodity markets and, as a result, tends to be more cyclical than aftermarket sales), will likely decrease. As a result of this cyclicality, we have experienced, and in the future could experience, extended periods of reduced sales and margins.

Because our customers’ purchasing patterns are affected by a variety of factors beyond our control, our sales and operating results may fluctuate significantly from period to period. Given the large sales prices of some of our equipment, one or a limited number of machines may account for a substantial portion of our sales in any particular quarter or other period. Although we recognize sales on a percentage-of-completion basis for most of our original equipment, the timing of one or a small number of contracts in any particular period may nevertheless affect our operating results. In addition, our sales and gross profit may fluctuate depending upon the sizes and the requirements of the particular contracts we enter into in that period.

Changes in global financial markets and global economic conditions could adversely affect our business.

Conditions in the global financial markets and economic conditions affect our results of operations. The recent global financial crisis has caused extreme volatility and tightening in the global capital and credit markets. The decreased availability of credit or the inability to obtain

third-party financing has resulted in our customers deferring capital expenditures, which could continue to adversely affect the demand for our mining equipment. Also, further deterioration in the global economy could lead to higher unemployment, lower consumer spending, reduced investment by businesses and reduced corporate earnings. This could result in our customers further deferring capital expenditures, which could adversely affect the demand for our mining equipment.

In addition, poor conditions in global financial markets or global or regional recessionary economic conditions could lead to the cancellation or delay of existing orders, difficulty in collecting outstanding accounts receivable and affect the financial viability of our suppliers, some of which we may consider key suppliers. The occurrence of any of these items individually or in the aggregate, could have a material adverse effect on our financial position, results of operations and cash flows.

We currently generate funds from our operations and utilize our revolving credit facilities to pay our operating expenses, fund our capital expenditures, pay dividends and fund our employee retirement benefit programs. If changing economic conditions negatively affect our results of operations and cash flows or increase the underfunding of our pension obligations, and the use of our revolving credit facilities is maximized, we may require access to capital and/or credit markets and our access to those markets may be limited, which could have a material adverse affect on our financial position and results of operations.

A material disruption to our manufacturing plants could adversely affect our ability to generate revenue.

We produce most of our surface mining original equipment and aftermarket parts at our manufacturing plants in the United States, Germany, Mexico, the United Kingdom and Australia, and most of our underground mining original equipment and aftermarket parts at our manufacturing plants in Germany and the United States and, to a lesser extent, in China, Australia and the Czech Republic. If operations at any of these facilities were to be disrupted as a result of equipment failures, natural disasters, work stoppages, power outages or other reasons, our business, financial position and results of operations could be materially adversely affected. Any of these significant events could require us to make large unanticipated capital expenditures. Interruptions in production could increase our costs and delay our delivery of original equipment and parts in production. Production capacity limits could cause us to reduce or delay sales efforts until production capacity is available. All of our facilities are also subject to the risk of catastrophic loss due to fires, explosions or adverse weather conditions. Lost sales or increased costs that we may experience during the disruption of operations may not be recoverable under our insurance policies, and longer-term business disruptions could result in a loss of customers. If this were to occur, our future sales levels, and therefore our future financial position, results of operations and cash flow, could be materially adversely affected.

Our results of operations are dependent on the commodity price of coal and other conditions in the coal markets.

For the year ended December 31, 2010, substantially all of our underground mining sales and approximately 20% of our surface mining original equipment sales were to coal mining customers. Many of these customers supply coal as fuel for the production of electricity in the United States and other countries. Government regulation of electric utilities and greenhouse gas emissions may adversely impact the demand for coal to the extent that such regulations cause or require such utilities to select alternative energy sources a source of electric power. If a more economical form of electricity generation is discovered, developed or mandated, or if a current alternative source of energy such as nuclear, wind or solar power becomes more widely accepted or cost effective, or if diminished economic activity reduces demand for steel, the demand for our mining equipment could be adversely affected.

We operate in a highly competitive industry.

Methods of competition in our business are diverse and include price, customer relationships, lead times, operating costs, productivity of equipment, design and performance, technology, reliability, warranty, service, delivery and other commercial factors, as well as government mandates to purchase their mining equipment from local suppliers. In electric mining shovels and draglines, we have a major international competitor and for certain applications our small electric mining shovels may also compete against the biggest diesel hydraulic excavators made by several worldwide manufactures and local and regional competitors, including quasi-governmental competitors. In the hydraulic excavators, drill, and off-highway haul truck markets, we compete with several worldwide manufacturers. In the aftermarket business, we compete with several worldwide manufacturers and numerous independent firms that produce copies of the parts manufactured by us and other original equipment manufacturers. In our underground mining segment, we have a major international competitor for the sale of continuous miners, longwall shearers, powered roof supports, armored face conveyers (“AFC”) and other underground mining equipment, as well as with a number of both established and emerging worldwide manufacturers of such equipment. In China, India. Poland and Russia, we also face competition from regional and domestic equipment manufacturers, including manufacturers owned directly or indirectly by governmental entities. For example, in China there is much pressure to increase domestic purchases for roof supports and to reduce the cost of roof supports which are imported. This circumstance could make it more difficult for us to compete effectively in China for certain products. As those markets and markets in other industrialized countries continue to develop, this competition may increase.

Certain of our competitors may have greater financial, marketing, manufacturing or distribution resources than we do. Demand for our products may be affected by our ability to respond to downward pricing pressure from our competitors or to continue to provide shorter lead time and quicker delivery of our products than our competitors. We cannot assure you that our products will continue to compete successfully with those of our competitors or that we will be able to retain our customer base or improve or maintain our profit margins on customer sales. If we are unable to maintain our profit margins, our results of operations could be materially adversely affected.

In any given year, we rely on significant customers for a large percentage of our sales.

Our business is dependent on securing and maintaining customers by promptly delivering reliable and high-performance products. We do not believe we are dependent upon any single customer; however, on an annual basis a single customer may account for a large percentage of our sales, particularly original equipment sales. Our top five surface mining customers in each of the years ended December 31, 2010, 2009 and 2008 collectively accounted for approximately 27%, 50% and 43%, respectively, of our total surface mining sales and our top five underground mining customers collectively accounted for approximately 29%, 41% and 43%, respectively, of our total underground mining sales for the years ended December 31, 2010, 2009 and 2008, respectively. We believe these relatively high percentages reflect the recent consolidation within the mining industry. In addition, key sectors of the mining industry are dominated by a few enterprises, most of which are our customers. The loss of one or more of our significant customers or significantly reduced sales orders from significant customers could have a material adverse effect on our results of operations, financial condition and cash flows.

The loss of key members of our management team could adversely affect our business.

Our success substantially depends upon our ability to attract and retain qualified employees and upon the ability of senior management and other key employees to implement our business strategy and maintain and enhance our customer and supplier relationships. We believe there are only a limited number of available qualified chief executives in our industry. We rely substantially upon the services of our executive officers, and the loss of their services or the services of other members of our management team or our inability to attract or retain other talented personnel could impede the further implementation of our business strategy, which could have a material adverse effect on our business.

We are subject to risks of conducting business in foreign countries, including emerging markets.

We derive the majority of our sales from foreign markets where we have substantial operations. For the year ended December 31, 2010, we generated $2.9 billion, or approximately 81%, of our sales outside the United States (exports from the United States and sales by our foreign subsidiaries) compared to $1.9 billion, or 71%, for the year ended December 31, 2009. Various political, regulatory or economic factors, or changes in those factors, have the potential to adversely affect our international operations and our financial results. These factors principally include:

•

tariffs and price controls;

•

trade sanctions and embargos;

•

reduction in government subsidies;

•

import or export licensing requirements;

•

economic downturns, civil disturbances or political instability;

•

employment regulations;

•

nationalism;

•

regulations regarding repatriation of earnings;

•

ability to enforce contract and intellectual property rights;

•

availability of credit;

•

natural disasters;

•

national and international conflicts, including terrorist acts;

•

nationalization and expropriation;

•

potentially burdensome taxation; and

•

government corruption.

In addition, a significant portion of our international business is conducted in emerging and developing markets located in Asia, Africa, South America and Eastern Europe. Many of the countries in these regions have developing legal and economic systems, which add a level of uncertainty to our operations in those countries relative to those that would be expected domestically. Our customers in the developing markets of China, India and Eastern Europe have exposed us the uncertainty associated with the developing governmental, legal and economic systems in those countries. We have recently finalized a joint venture with a local partner to expand our manufacturing capacity in China, which will further increase our exposure to the uncertainties in this emerging market.

The above factors, and related unpredictability, could place our operations and business relationships in overseas markets at risk, which could materially adversely affect our financial position and results of operations.

We are subject to risks related to conducting business in foreign currencies.

We are subject to foreign currency exchange risk because we sell a significant amount of our underground mining products in euros, while we sell most of our surface mining original equipment in United States dollars, and we report our combined consolidated results in United States dollars. As a result, an increase in the value of the United States dollar or the euro, relative to other nations’ currencies, would decrease the United States dollar or euro equivalent of our underground mining sales earned without decreasing the United States dollar or euro value of the expenses associated with its sales.

Additionally, a portion of our aftermarket parts sales is denominated in the currency of the country in which the products are sold and the majority of our service sales are denominated in local currencies. Although a portion of the expenses of providing overseas services are denominated in local currencies, the cost of goods associated with overseas sales are generally incurred in United States dollars and euros. As a result, an increase in the value of the United States dollar or the euro relative to these nations’ currencies would decrease the United States dollar or euro equivalent of aftermarket sales earned abroad without decreasing the United States dollar or euro value of a portion of the expenses associated with overseas sales.

Currency controls, devaluations, trade restrictions and other disruptions in currency convertibility and in the market for currency exchange could limit our ability to convert revenues earned abroad into United States dollars or euros in a timely manner. This could adversely affect our ability to service our United States dollar or euro indebtedness, fund our United States dollar or euro costs, finance capital expenditures and pay dividends on our common stock. Therefore, our future results of operations may be subject to increased volatility.

Regulations affecting the mining industry or electric utilities may reduce demand for our products and services.

Our principal customers are mining companies. Many of these customers supply coal as a power generating source for the production of electricity in markets around the world. The operations of these mining companies are geographically diverse and are subject to or affected by a wide array of regulations in the jurisdictions in which they operate, including those with a direct impact on mining activities and those indirectly affecting their businesses, such as applicable environmental laws and regulations governing the operation of coal-fired power plants. As a result of changes in regulations and laws relating to the operation of mines, our customers’ mining operations could be disrupted or curtailed by governmental authorities. The high cost of compliance with mining and environmental regulations may also induce customers to discontinue or limit their mining operations, and may discourage companies from developing new mines. Additionally, government regulation of coal-fired power plants may adversely impact the demand for coal to the extent that such regulations cause electric utilities to select alternative energy sources and technologies as sources of electric power. Domestic and international initiatives to regulate greenhouse gas emissions, including carbon dioxide could depress coal consumption in Western economies. If demand for coal declines, demand for our products will also decline, which would have a material adverse effect on our financial position and results of operations.

We may be adversely affected by environmental and safety regulations or concerns.

We are subject to increasingly stringent environmental and occupational health and safety laws and regulations in the countries in which we operate, including laws and regulations governing emissions to air, discharges to water and the generation, handling, storage, transportation, treatment and disposal of, or exposure to, hazardous materials. Although it is our intent to comply with such laws and regulations, we cannot assure you that we have always done so on a historical basis, or will continue to do so prospectively. If we are not in compliance with these laws and regulations, we may incur remediation obligations or other costs in excess of amounts reserved, or fines, penalties or suspension of production. We may be adversely impacted by costs, liabilities or claims with respect to existing or subsequently acquired operations, under either present laws and regulations or those that may be adopted or imposed in the future.

Our operations are also subject to laws requiring the cleanup of contaminated property. If a release of hazardous substances occurs, or has occurred, at or from any of our current or former properties or at a landfill or another location where we have disposed of hazardous materials, we may be held liable for the contamination, and the amount of such liability could be material.

In addition, increased environmental regulation of the mining industry in North America and overseas could increase costs to us or to our customers and adversely affect the sales of our products and future operating results. These requirements may change in the future in a manner that could require us to make capital and other expenditures, which could have a material adverse effect on our financial position and results of operations.

We must attract and retain skilled labor in order to maintain and increase our business.

Our ability to operate profitably and expand our operations depends in part on our ability to attract and retain skilled manufacturing workers, equipment operators, engineers and other technical personnel. Also, our underground mining business will face the retirement of a large number of skilled employees over the next five to 10 years. As a result, our growth may be limited by the scarcity of skilled labor. Additionally, a significant increase in the wages paid by competing employers could result in a reduction in our skilled labor force, increases in the rates of wages we must pay or both. Further, we may be faced with increased training costs and reduced productivity as we train new employees. If our compensation costs increase or we cannot attract and retain skilled labor, including engineers, machinists and welders, our earnings could be reduced, and production capacity and growth potential could be impaired.

If we fail to offer technologically advanced equipment to our customers, demand for our products may be materially adversely affected.

We believe that most of our mining industry customers are focused on improving automation, standardization and consolidation of equipment and mining operations. In this regard, we concentrate on producing technologically advanced equipment that allows our customers to conduct safe and cost-efficient operations. To remain competitive, we believe we must develop new and innovative products on an ongoing basis. If we are unable to continue developing new and innovative products that incorporate technological advancements and meet the evolving requirements of our customers, or if we are unable to successfully bring such products to market, or if our competitors produce and sell equipment that is more technologically advanced or otherwise better received in the marketplace than ours, the demand for our mining equipment could be materially adversely affected.

Labor disruptions could adversely affect our operations.

At December 31, 2010, approximately 3,400 of our employees were unionized. Our contract with the United Steelworkers of America representing hourly workers at our South Milwaukee facility expires in April 2013, our contract with the United Steelworkers representing hourly workers at our Pulaski, Virginia facility expires in August 2011, and our contract with the United Steelworkers of America representing hourly workers at our Denison, Texas facility expires in May 2015. Many of the collective bargaining agreements relating to our underground mining non-United States employees may be terminated by either the union or the employer association with a one to three month notice period (although these agreements will remain in full force and effect until a new agreement has been reached). After expiration of these agreements, we are not assured of being able to reach new agreements without a work stoppage or strike, and any new agreements may not be reached on terms satisfactory to us, may be on substantially different terms from our current agreements and may result in increased direct and indirect labor costs. A dispute between our employees and us could divert significant management time and attention and disrupt our operations, and the resulting adverse impact on our relationships with customers could reduce our revenue. Also, a few of our mine site operations and production and other facilities are located in areas of high union concentration or in nations with laws favorable to unionization, and, as a result, such operations and facilities are susceptible to union organizing activity. Additionally, our obligations under underground mining business labor agreements may prevent us from taking actions that we

might otherwise deem prudent in connection with the operation of our underground mining business, which could have a material adverse effect on our financial position and results of operations.

In addition, the workforces of many of our suppliers and our transportation providers are unionized. If they are disrupted by labor issues, delivery of parts and materials to us could be reduced or delayed. Many of our customers have unionized work forces, and work stoppages experienced by our customers could cause us to lose sales or incur increased costs.

Our continued success depends in part on our ability to protect our intellectual property.

Our future success depends in part on our ability to protect our intellectual property. We rely principally on nondisclosure agreements and other contractual arrangements and trade secret laws and, to a lesser extent, trademark and patent law, to protect our intellectual property, including jointly developed intellectual property. However, these measures could prove inadequate to protect our intellectual property from infringement by others or to prevent misappropriation of our proprietary rights. In addition, the laws and enforcement mechanisms of some foreign countries do not protect proprietary rights to the same extent as do United States laws. We expect that the expansion of our manufacturing capacity in China and potentially to other countries such as India or Brazil also may heighten our risk of intellectual property infringement due to the pervasive nature in those countries of independent firms called “will-fitters” that produce copies of the parts manufactured by us and other original equipment manufacturers. Our inability to protect our proprietary information and enforce intellectual property rights through infringement or other enforcement proceedings could have a material adverse effect on our financial position and results of operations.

The acquisition of Terex Mining was financed, in large part, with a $1.0 billion term loan which substantially increased our debt service obligations. As a result, we may have less cash flow available for business operations, we could become increasingly vulnerable to general adverse economic and industry conditions and interest rate trends, and our ability to obtain future financing may be limited.

We entered into an amendment to our then existing credit agreement to provide for an additional new secured term loan of $1.0 billion and $167.5 million of revolving credit facilities to fund the cash portion of the purchase price for Terex Mining and to support our future working capital needs and capital expenditure plan.

Our ability to make required payments of principal and interest on our debt levels will depend on future performance of our combined businesses, which, to a certain extent, is subject to general economic, financial, competitive and other factors that are beyond our control. In addition, our amended credit agreement contains financial and restrictive covenants that may limit our ability to, among other things, borrow additional funds or take advantage of business opportunities. Our failure to comply with such covenants could result in an event of default that, if not cured or waived, could result in the acceleration of all our indebtedness or otherwise have a material adverse effect on our financial position, results of operation and debt service capability.

Our increased level of debt and the financial and restrictive covenants contained in our amended new credit agreement could have important consequences on our financial position and results of operations, including:

•

increasing our vulnerability to general adverse economic and industry conditions and detraction from our ability to successfully withstand a downturn in our markets or the economy generally;

•

requiring us to dedicate a substantial portion of our cash flow from operations to required payments on debt, thereby reducing the availability of such cash flows to fund working capital, capital expenditures, manufacturing capacity expansion, additional business opportunities and other general corporate activities;

•

limiting our ability to obtain additional financing in the future to fund working capital, capital expenditures, manufacturing capacity expansion, additional business opportunities and other general corporate requirements;

•

limiting our flexibility in planning for, or reacting to, changes in our business and the markets we serve;

•

placing us at a competitive disadvantage compared to less leveraged competitors; and

•

making us vulnerable to increases in interest rates because debt under our amended credit facility bears interest at variable rates.

Our customers’ inability to obtain loan guarantees or other credit enhancements or financing from the Export-Import Bank of the United States, Hermes of Germany or other sources to support their purchase of our equipment could adversely impact our results of operations.

Many of our targeted customers operate in developing countries and markets. Some of our customers in these countries and markets may rely on loan guarantees, credit enhancements or other sources of financing to support their purchase orders for our equipment, including through the Export-Import Bank of the United States or Hermes of Germany. If these customers are unable to receive such loan guarantees, credit enhancements or financing from the Export-Import Bank, Hermes or other sources, or if they experience significant delays in the receipt of or are subjected to significant or burdensome terms and conditions in obtaining such loan guarantees, credit enhancements or financing, then they may place their equipment orders with other manufacturers, including foreign manufacturers. As a consequence, our results of operations could be materially adversely affected.

Aspects of our operations are dependent on relationships with local partners in some countries.

In certain countries we have formed relationships with local partners to manufacture, sell or service our products. For example, we have a commercial agreement with a local partner in India and we have recently finalized a joint venture with a local partner in China, each with respect to certain limited aspects of our operations in these countries. These and other countries may require us to use additional local partners in connection with our operations in such countries. The use of local partners may adversely impact our margins and profitability in such countries and disputes with local partners may adversely impact our operations in the applicable countries.

We may have liabilities relating to Terex Mining which are not known to us.

As part of the acquisition of Terex Mining, we assumed some of Terex Mining’s liabilities and risks after the closing of the transaction, subject to certain representations and warranties of, and indemnification rights against, Terex Corporation. There may be liabilities or risks that we failed, or were unable, to discover in the course of performing our due diligence investigations of Terex Mining. Additionally, Terex Mining has made previous acquisitions and we may be subject to potential liabilities and risks relating to these prior acquisitions as well. We cannot assure you that our rights to indemnification contained in our Asset and Stock Purchase Agreement will be sufficient in amount, scope or duration to fully offset the possible liabilities associated with the business or property acquired. Any such liabilities, individually or in the aggregate, could have a material adverse effect on our financial position and results of operations. We may learn additional information about Terex Mining that adversely affects us, such as unknown or contingent liabilities and issues relating to compliance with applicable laws or issues related to ongoing customer relationships or order demand.

To remain compliant with the obligations imposed on us by the Sarbanes-Oxley Act of 2002, we may be required to make significant changes in the internal controls, information systems and technologies or other aspects of Terex Mining’s business.

Section 404 of the Sarbanes-Oxley Act of 2002 requires public companies like ours to review and make certain disclosures regarding their internal controls over financial reporting. We are also required to maintain certain disclosure controls and procedures and to take certain other actions and implement certain other practices and procedures, in order to remain compliant with other sections of the Sarbanes-Oxley Act of 2002, as well as other rules and regulations of the SEC applicable to us. In the past, we have undertaken efforts, at substantial cost, to become compliant with these rules and regulations, including the documentation, testing and review of our internal controls over financial reporting under the direction of senior management and the implementation of a system of disclosure controls and procedures. We have not completed our testing and review of the internal controls over financial reporting currently maintained by Terex Mining and, as a result, do not know whether such internal controls are sufficient to allow us to identify significant deficiencies and material weaknesses in their design or operation which are reasonably likely to adversely affect our ability to record, process, summarize and report financial information and/or detect fraud. If Terex Mining’s internal controls over financial reporting are not adequate or in conformity with the requirements of the Sarbanes-Oxley Act of 2002, we may be required to use significant financial and managerial resources to implement a compliant system or to disclose significant deficiencies or material weaknesses, which may subject us to penalties and other enforcement actions. Nevertheless, we have commenced this analytical process. We may also be required to use

significant financial and managerial resources to implement a system of disclosure controls and procedures at Terex Mining to ensure that material information relating to Terex Mining is made known to us in a timely fashion. These actions may have a material adverse effect on our financial position and results of operations.

We have entered a new line of business and new geographic markets in which certain of our competitors have substantially more experience than we do.

Through the acquisition of Terex Mining, we have entered the market for the production, sale and service of original equipment and spare parts for additional equipment lines primarily used in surface mining including hydraulic shovels, off-highway haul trucks, highwall miners, hydraulic track drills and consumables. There can be no assurance that the business strategies applicable to our operations with respect to surface or underground mining, or the manner in which we have implemented those strategies, will be effective in the additional product lines or geographic markets, or that we will be able to develop and implement alternative successful strategies, including strategies used to increase aftermarket sales and services. If we are unable to effectively manage the acquired operations or compete against our competitors who are more established in their respective product lines, our operating results could be materially adversely affected.

We are in the process of implementing a global enterprise resource planning (“ERP”) system in our surface mining segment.

We are in the process of implementing a new global ERP system in our surface mining segment. This system will replace our surface mining segment’s existing operating and financial system. If the system is not implemented successfully and within budget or if the system does not perform in a satisfactory manner, it could be disruptive and or adversely affect our operations and results of operations, including our ability to report accurate and timely financial results.

We may have to utilize significant cash to meet our unfunded pension obligations, and these obligations are subject to increase.

A substantial portion of our United States employees participate in our defined benefit pension plans. At December 31, 2010, our unfunded pension liability for these plans totaled $14.0 million compared to $13.8 million at December 31, 2009. Declines in interest rates or the market values of the securities held by the plans, or other adverse changes, could materially increase the underfunded status of these plans and affect the level and timing of required cash contributions in 2010 and after. In addition, at December 31, 2010, we had $129.7 million in unfunded pension liabilities with respect to pension plans for certain non-United States employees, with minimal assets set aside to fund such obligations, compared to $119.0 million at December 31, 2009. Declines in interest rates or other adverse changes could materially increase the underfunded status of these plans.

Our mining production capacity may not be sufficient to meet customer demand.

Our backlog of firm orders was $2.7 billion at December 31, 2010. Production capacity at all of our manufacturing locations may not be sufficient to satisfy customer demand for our surface mining products from time to time. If we are unable to commit to producing products for customers within the timeframes they require, then these customers may seek to procure equipment from other sources to meet their project deadlines, which could adversely affect our future sales levels, profitability and cash flow.

We are, and may be in the future, subject to product liability and other lawsuits related to past and current activities.

The selling and servicing of complex, large scale surface mining equipment used in a variety of locations and climates, and integrating a variety of manufactured and purchased components entails an inherent risk of lawsuits and liability relating to the operation and performance of the equipment and the health and safety of the workers who operate and come into contact with it. We have been named as a co-defendant in numerous pending personal injury liability cases alleging damages caused by exposure to asbestos and other substances, and the particular circumstances of many of these cases are difficult to assess because the claims allege exposure to a variety of substances from various sources over varying historical periods and assert the culpability of multiple defendants. Our underground mining business is also subject to various product liability and personal injury claims, including those relating to alleged asbestos and silicosis exposure. These types of claims, as well as product liability claims in general, can be expensive to defend and can divert the attention of management and other personnel for long periods of time, regardless of the ultimate outcome. While we maintain product liability and other insurance to cover varying levels of claims of this nature, including varying levels of coverage for the historical periods during which the pending claims of which we are aware allege asbestos exposure, those policies are subject to deductibles and recovery limitations, and there are limitations on events covered by the policies. Also, there can be no assurance that we will be able to obtain insurance on acceptable terms in the future, if at all, or obtain insurance that will provide adequate coverage against potential future claims. These lawsuits and future lawsuits against us could be resolved in a manner that materially and adversely affects our product reputation, business, financial position and results of operations.

If we are unable to purchase component parts or raw materials from key suppliers, the prices of component parts or raw materials rise materially, or the costs of shipping products rise materially, our business and results of operations may be materially adversely affected.

We purchase most of our alternating current (“AC”) drives and certain electrical parts for our surface mining equipment pursuant to a 10-year agreement, which ends in February 2016, with Siemens Energy & Automation (“Siemens”). Delays, disruptions or other difficulties procuring parts from Siemens, or our inability to obtain parts from Siemens altogether could have a material adverse effect on our business and results of operations. We currently purchase motors, an important component of our room and pillar equipment, from one supplier. The loss of this supplier could cause a delay in manufacturing due to the time required to have motors of a new supplier approved and certified by the Mine Safety and Health Administration and other similar approval agencies around the world. The loss of this supplier could also result in a possible loss of sales, which could have a material adverse effect on our business and results of operations. We purchase components for our roof supports from three primary suppliers pursuant to written agreements. The loss of any of these three primary suppliers, or

delays, disruptions or other difficulties procuring parts from these suppliers or from related raw material sources, could have a material adverse effect on our ability to timely produce our roof supports and other underground mining original equipment and, ultimately, could have a material adverse effect on our business and results of operations. We also purchase track links, castings and forgings from suppliers with whom we have longstanding relationships. Although these are not sole source suppliers, the loss of these suppliers could affect our ability to maintain costs.

If we are required to procure alternative sources of supply, our ability to supply parts to our customers when needed could be impaired, we could lose business and our margins and cash flow could be reduced. Also, because we maintain limited production input inventories, even brief unanticipated delays in delivery by suppliers, including those due to capacity constraints, labor disputes, impaired financial position of suppliers, weather emergencies or other natural disasters, may impair our ability to satisfy our customers and could adversely affect our operations.

In addition, we use substantial quantities of steel in our production processes. If the price of steel or other raw materials increases and we are unable to recover those price increases, or if availability of certain types of steel decreases and we are not able to acquire sufficient quantities of this steel, we will experience reduced margins. Any significant future delays in obtaining production inputs and other supplies could result in our delay in delivering or producing products for our customers, which could subject us to contractual damage claims or otherwise harm our business and results of operations. In addition, there recently has been consolidation within the steelmaking industry, which could impede our ability to rely on competitive balance and longstanding business relationships to procure steel on favorable terms and in a timely manner.

We also purchase component parts and raw materials on terms extended to us by our suppliers based on our overall credit rating. If our credit rating were to change adversely, our suppliers may not be willing or able to continue to extend favorable terms to us, which could negatively impact our cash flow or cause us to incur increased indebtedness under our revolving credit facility.

Some of our contracts require us to bear all costs of shipping and handling to the customer’s site. Because of the size and weight of our products, these costs can be a significant portion of the total costs of a given contract. If transportation costs rise materially due to fuel prices or other factors, our gross margins could be reduced.

ITEM 2.

PROPERTIES

Our principal surface mining manufacturing operations are located in South Milwaukee, Wisconsin, Dortmund, Germany; Dennison, Texas; Acuna, Mexico; Beckley, West Virginia; Halifax, United Kingdom and Perth, Australia.

South Milwaukee and Milwaukee, Wisconsin. Our South Milwaukee facility is located on approximately 66 acres of land and comprises several buildings totaling approximately 1,100,000 square feet of floor space, including approximately 852,000 square feet for

manufacturing and manufacturing support. A portion of this facility houses our corporate headquarters and surface mining research and development facilities. The major buildings at this facility are constructed principally of structural steel, concrete and brick and have sprinkler systems and other devices for protection against fire. The buildings and equipment therein, which include specialized machine tools and equipment for fabrication, welding and assembly of our surface mining machinery, including draglines, electric mining shovels and rotary blasthole drills, are well-maintained, in good condition and in regular use. We lease the majority of the land and buildings at our South Milwaukee facility. The term of the lease is 20 years through 2021 with the option to renew the lease for up to five five-year terms at our option. Annual rent under the lease is $1.1 million through 2016.

ITEM 3.

LEGAL PROCEEDINGS

Product Liability

We are normally subject to numerous product liability claims, many of which relate to products no longer manufactured by us or our subsidiaries, and other claims arising in the ordinary course of business in federal and state courts. Such claims are generally related to property damage and to personal injury. Our products are operated by us and our customers’ employees and independent contractors at various work sites in the United States and abroad. In the United States, workers’ claims against employers related to workplace injuries are generally limited by state workers’ compensation statutes, but such limitations do not apply to equipment suppliers. In addition, independent contractors may not be subject to state workers’ compensation regimes. We have insurance covering most of these claims and various limits of liability depending on the insurance policy year in question. We do not believe that the costs and/or final resolution of these claims and other similar adverse claims which are likely to arise in the future will individually or in the aggregate have a material effect on our financial position, results of operations or cash flows, although no assurance to that effect can be given.

Suits Alleging Exposure to Asbestos and Other Substances

We have been named as a co-defendant in numerous personal injury liability cases alleging damages due to exposure to asbestos and other substances. These cases are pending in courts in various states. In most of these cases, insurance carriers have accepted or are expected to accept defense. These cases are in various pre-trial stages. We do not believe that costs and/or final resolution of these claims will individually or in the aggregate have a material effect on our financial position, results of operations or cash flows, although no assurance to that effect can be given.

Other

In August 2010, we received letters from the U.S. Department of Justice and from the U.S. Securities and Exchange Commission (“SEC”) requesting certain documents and information and notifying us that the SEC is conducting a non-public, fact-finding inquiry of us. We are cooperating fully with this inquiry.

We are also involved in various other litigation in the United States and abroad arising in the normal course of business. We do not believe that our recovery or liability, if any, under any such pending litigation will have a material effect on our financial position, results of operations or cash flows, although no assurance to that effect can be given.

Environmental and Related Matters

Our operations and properties are subject to a broad range of federal, state, local and foreign laws and regulations relating to environmental matters, including laws and regulations governing discharges into the air and water, the handling and disposal of solid and hazardous substances and wastes, and the remediation of contamination associated with releases of hazardous substances at our facilities and at off-site disposal locations. These laws are complex, change frequently and have tended to become more stringent over time. Future events, such as required compliance with more stringent laws or regulations, more vigorous enforcement policies of regulatory agencies or stricter or different interpretations of existing laws, could require additional expenditures by us, which may be material.

Environmental problems have not interfered in any material respect with our manufacturing operations to date. We believe that our compliance with current statutory requirements respecting environmental quality will not have a material adverse affect on our financial position, results of operations or cash flows, although no assurance to that effect can be given. We have an ongoing program to address potential environmental problems.

Certain environmental laws, such as the Federal Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”), provide for strict, joint and several liability for investigation and remediation of spills and other releases of hazardous substances. Such laws may apply to conditions at properties currently or formerly owned or operated by an entity or its predecessors, as well as to conditions at properties at which wastes or other contamination attributable to an entity or its predecessors come to be located.

We have previously been named as a potentially responsible party under CERCLA and analogous state laws at sites throughout the United States. We believe we have determined our cleanup liabilities with respect to these sites and do not believe that any such remaining liabilities, if any, either individually or in the aggregate, will have a material adverse effect on our financial position, results of operations or cash flows, although no assurance to that effect can be given. We may incur additional liabilities with respect to these sites in the future, the costs of which could be material, and may incur remediation liability in the future with respect to sites formerly or currently owned or operated by us, or with respect to off-site disposal locations, the costs of which could be material.

Over the past three years, expenditures for ongoing compliance, remediation, monitoring and clean-up have been immaterial. While no assurance can be given, we believe that expenditures for compliance and remediation will not have a material adverse effect on our financial position, results of operations or cash flows, although no assurance to that effect can be given.

Litigation Relating to the Proposed Merger With Caterpillar Inc.

Between November 16, 2010 and December 30, 2010, six putative class actions – five in Wisconsin Circuit Court and one in Delaware Chancery Court – were filed concerning the proposed merger between Badger Merger Sub., a wholly owned subsidiary of Caterpillar Inc., and us.

On November 16, 2010, a lawsuit was filed against us and each of our directors, Caterpillar Inc., and Badger Merger Sub. The case is captioned Evelyn Greenberg, et al. v. Bucyrus International, Inc., et al. Wisconsin Circuit Court, Milwaukee County, Case No. 10CV19342. The lawsuit was filed by a person claiming she is a stockholder of ours and purporting to act on behalf of herself and a class of other similarly situated stockholders. Two other putative class actions were filed on the same date against the same defendants in the same court in Wisconsin; another putative class action was also filed in the same court on November 19, 2010. These cases have been removed to the United States District Court for the Eastern District of Wisconsin and are captioned Evelyn Greenberg, et al. v. Bucyrus International, Inc., et al., Case No. 10-CV-1103-CNC; Daniel Himmel, et al. v. Bucyrus International, Inc., et al., Case No. 10-CV-1104-CNC; Thomas Turberg, et al. v. Bucyrus International, Inc., et al., Case No. 10-CV-1105-CNC; and City of Sterling Heights Police & Fire Retirement System, et al. v. Bucyrus International, Inc., et al., Case No. 10-CV-1106-CNC. On December 30, 2010, a lawsuit was filed against us and each of our directors, Caterpillar Inc., and Badger Merger Sub Inc., in the United States District Court for the Eastern District of Wisconsin and is captioned Edmund J. Impens, et al. v. Sullivan, et. al., Case No. 10-CV-1179-CNC.

In addition, on November 17, 2010, a putative class action was filed in Delaware Chancery Court, captioned Margaret C. Richardson, et al. v. Bucyrus International, Inc., et al., Case No. 5998, against us and each of our directors and Caterpillar Inc.

In each of the actions, the plaintiffs allege that, by approving the merger agreement, our directors allegedly violated a fiduciary duty owed to our stockholders because the price to be paid pursuant to the merger agreement is allegedly inadequate and the process through which it was obtained was allegedly unfair. The plaintiffs further allege that Caterpillar Inc. aided and abetted such alleged violations. Plaintiffs allege that the class has and will be damaged by these breaches of duty, and that the class is entitled to an injunction preventing the consummation of the merger, monetary damages and attorneys’ fees.

On December 14, 2010, the plaintiffs in the Greenberg and Turberg actions amended their complaints, restating their claims of breach of fiduciary duty and aiding and abetting a breach of fiduciary duty. They also added claims that we and the individual defendants violated Sections 14(a) and 14(e) of the Securities Exchange Act by allegedly issuing a misleading proxy statement, and that the individual defendants had “controlling person” liability under Section 20(a) of the Securities Exchange Act with respect to the proxy statement. On December 28, 2010, we filed motions to dismiss arguing that plaintiffs have failed to state a claim. A briefing schedule has been set.

On December 20, 2010, the plaintiffs in the City of Sterling Heights action amended their complaint, adding claims that the individual defendants and Caterpillar, Inc. violated Sections 14(a) and 20(a) of the Securities Exchange Act. On January 3, 2011, we filed a motion to dismiss asserting that plaintiffs have failed to state a claim. A briefing schedule has been set.

On December 21, 2010, the plaintiffs in Himmel, filed a motion for remand to state court instead of filing an amended complaint. A briefing schedule has been set.

Our directors and us, Caterpillar Inc. and Badger Merger Sub believe the actions are without merit and intend to defend them vigorously.

CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

In accordance with Rule 13a-15(b) of the Securities Exchange Act of 1934 (the “Exchange Act”), our management evaluated, with the participation of our Chief Executive Officer and Chief Financial Officer and Secretary, the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act) as of December 31, 2010. Based upon their evaluation of these disclosure controls and procedures, our Chief Executive Officer and Chief Financial Officer and Secretary concluded that the disclosure controls and procedures were effective as of December 31, 2010 to ensure that information required to be disclosed by us in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time period specified in the Securities and Exchange Commission rules and forms, and to ensure that information required to be disclosed by us in the reports we file or submit under the Exchange Act is accumulated and communicated to our management, including our principal executive and principal financial officers, as appropriate, to allow timely decisions regarding required disclosure. Management has excluded the Terex Mining business from its assessment of internal control over financial reporting as of December 31, 2010 because we acquired Terex Mining during 2010. The total assets and total revenues of the Terex Mining business represented approximately 39% and 28%, respectively, of our consolidated financial statement amounts as of and for the year ended December 31, 2010.
