PART I

Item 1. Business

Lufkin Industries, Inc. (the “Company”) was incorporated under the laws of the State of Texas on March 4, 1902, and since that date has maintained its principal office and manufacturing facilities in Lufkin, Texas. The Company, a global supplier of oil field and power transmission products, is divided into two operating segments: Oil Field and Power Transmission.

On November 1, 2010 the Company completed the acquisition of the significant operating assets of Petro Hydraulic Lift Systems, LLC (“PHL”) and certain related companies, based in South Louisiana. PHL, specializes in the design, manufacture and leasing of hydraulic rod pumping units for oil and gas wells.

Financial information by industry segment and geographic area is incorporated herein by reference to Note 17 – “Business Segment Information” in the Notes to Consolidated Financial Statements set forth in Part II, Item 8 of this annual report on Form 10-K.

The Company employed approximately 3,000 people at December 31, 2010, including approximately 2,000 people that were paid on an hourly basis. Certain of the Company’s operations are subject to a union contract that expires in October 2011.

No customer represented over 10% of consolidated company sales as of December 31, 2010. An Oil Field customer and its related subsidiaries represented 11.0% and 15.4% of consolidated company sales in 2009 and 2008, respectively.

Oil Field

Products:

The Oil Field segment manufactures and services artificial lift products, including reciprocating rod lift, commonly referred to as pumping units, gas lift, plunger lift equipment and related products.

Pumping Units - Five basic types of pumping units are manufactured: an air-balanced unit; a beam-balanced unit; a crank-balanced unit, a Mark II Unitorque unit; and a hydraulic unit. The basic differences between the five types relate to the counterbalancing system. The depth of a well and the desired fluid production determine the type of counterbalancing configuration that is required. The Company manufactures numerous sizes and combinations of Lufkin oil field pumping units within the five basic types.

Pumping Unit Service - Through a network of service centers, the Company transports and repairs pumping units. The service centers also refurbish used pumping units.

Automation - The Company designs, manufactures, installs and services computer control equipment and analytical services for artificial lift equipment that lower production costs and optimize well efficiency.

Lufkin ILS - Through this acquisition in 2009, the Company now designs, manufactures, installs and services gas lift, plunger lift and completion equipment.

Foundry Castings - As part of the Company’s vertical integration strategy, the Oil Field segment operates an iron foundry to produce castings for new pumping units. In order to maximize utilization of this facility, castings for third parties are also produced.

Raw Materials & Labor:

Oil Field purchases a variety of raw materials in manufacturing its products. The principal raw materials are structural and plate steel, round alloy steel and iron castings, which are purchased from both its own foundry and third-party foundries. Casting costs are subject to change, as a result of changes in raw material prices on scrap iron and pig iron in addition to changes in natural gas and electricity prices. Due to the many configurations of its products and thus sizes of raw material used, Oil Field does not enter into long-term contracts for raw materials but generally does not experience shortages of raw materials. During the period of 2008 through 2010, Oil Field did not experience any significant material shortages. During the first three quarters of 2008, raw material prices for steel and castings increased significantly but started declining in the fourth quarter of 2008 and through 2009. Raw material prices stayed relatively unchanged in 2010. As the global economy improves in 2011, raw material prices are expected to moderately increase. Raw material prices may continue to increase and availability may decrease with little notice.

The nature of the products manufactured and serviced by Oil Field generally requires skilled labor. Oil Field’s ability to increase capacity could be limited by its ability to hire and train qualified personnel. Also, the main U.S. manufacturing facilities are unionized, so any labor disruption could have a significant impact on Oil Field’s ability to maintain production levels. The current labor contract expires in October 2011.

Markets:

Demand for artificial lift equipment primarily depends on the level of new onshore oil well and workover drilling activity as well as the depth and fluid conditions of that drilling. Drilling activity is driven by the available cash flow of the Company’s customers as well as their long-term perceptions of the level and stability of the price of oil. The higher energy prices experienced since 2004 have increased the demand for artificial lift equipment and related service and products from higher drilling activity, activation of idle wells and the upgrading of existing wells. During 2008, demand in the North American market increased significantly due to the impact of increased drilling in response to higher oil prices and recapturing certain market share from lower-priced imported equipment as customers reevaluated the total life-cycle cost differences. In the fourth quarter of 2008, oil prices decreased significantly and stayed at reduced levels throughout 2009. As drilling activity reduced in response to lower oil prices, demand for artificial lift equipment and related service was also negatively impacted. Also, as raw material costs declined and surplus equipment increased, there was competitive pressure to lower selling prices. Lower selling prices combined with the negative impact of low capacity utilization in manufacturing facilities, caused gross margins to decline in 2009. Activity levels increased moderately during the second half of 2009 and early 2010. As the global economy began to recover in 2010 and oil prices and drilling activity rose, demand levels increased to near 2008 levels. This trend is expected to continue in 2011, with higher drilling activity and lower surplus equipment inventory driving demand for new artificial lift equipment. Longer-term, the demand for artificial lift equipment is also expected to continue to increase in international markets. While a majority of the segment’s revenues are in North America, international opportunities continue to increase as new drilling increases and existing fields mature, requiring increased use of artificial lift, especially in the South American, Russian and Middle Eastern markets.

Competition:

The primary global competitor for artificial lift equipment is Weatherford International, but Chinese manufacturers of artificial lift equipment are also present in the market. Used pumping units are also an important factor in the North American market, as customers will generally attempt to satisfy requirements through used equipment before purchasing new equipment. While the Company believes that it is one of the larger manufacturers of artificial lift equipment in the world, manufacturers of other types of equipment like electric submersible pumps have a significant share of the total artificial lift market. While Weatherford International is the Company’s single largest competitor in the service market, small independent operators provide significant competitive pressures.

Because of the competitive nature of the business and the relative age of many of the product designs, price, delivery time, product quality and customer service are important factors in winning orders. To this end, the Company maintains strategic levels of inventories in order to ensure delivery times and invests in new capital equipment to maintain quality and price levels.

Power Transmission

Products:

The Power Transmission segment designs, manufactures and services speed increasing and reducing gearboxes for industrial applications. Speed increasers convert lower speed and higher torque input to higher speed and lower torque output while speed reducers convert higher speed and lower torque input to lower speed and higher torque output. The Company produces numerous sizes and designs of gearboxes depending on the end use. While there are standard designs, the majority of gearboxes are customized for each application.

High-Speed Gearboxes - Single stage gearboxes with pitch line velocities equal to or greater than 35 meters per second or rotational speeds greater than 4500 rpm or multi-stage gearboxes with at least one stage having a pitch line velocity equal to or greater than 35 meters per second and other stages having pitch line velocities equal to or greater than 8 meters per second are classified as high-speed gearboxes. These gearboxes require extremely high precision manufacturing and testing due to the stresses on the gearing. The ratio of increasers to reducers is fairly even. These gearboxes more typically service the energy related markets of petrochemicals, refineries, offshore production and transmission of oil and gas.

Low-Speed Gearboxes - Gearboxes which do not meet the pitch line or rotational speed criteria of high-speed gearboxes are classified as low-speed gearboxes. The majority of low-speed gearboxes are reducers. While still requiring close tolerances, these gearboxes do not require the same precision of manufacturing and testing as high-speed gearboxes. These gearboxes more typically service commodity-related industries like rubber, sugar, paper, steel, plastics, mining and cement as well as marine propulsion.

Parts - The Company manufactures capital spares for customers in conjunction with the production of new gearboxes, in addition to producing parts for aftermarket service.

Gearbox Repair & Service - The Company provides on and off-site repair and service for not only its own products but also those manufactured by other companies. Repair work is performed in dedicated facilities due to the quick turn-around times required.

Lufkin RMT - Through this acquisition in 2009, the Company now participates in the turbo-machinery industry, specializing in the analysis design and manufacture of precision, custom-engineered tilting-pad bearings and related components for high-speed turbo equipment operating in critical duty applications. RMT also services, repairs and upgrades turbo-expander process units for air and gas separation.

Raw Materials & Labor:

Power Transmission purchases a variety of raw materials in manufacturing its products. The principal raw materials are steel plate, round alloy steel, iron castings and steel forgings. Due to the customized nature of its products, Power Transmission generally does not enter into long-term contracts for raw materials. Though raw material shortages are infrequent, lead times can be long due to the custom nature of many of its orders. Raw material prices are not expected to decline significantly in the short-term and may continue to increase with little notice. Certain materials like steel round, steel plate, steel forgings and bearings have continued to experience price increases and longer lead times. Raw material and component part shortages are not expected in the short-term, but certain supplier lead-times have grown, especially bearing suppliers.

The nature of the products manufactured and serviced by Power Transmission generally requires skilled labor. Power Transmission’s ability to increase capacity could be limited by its ability to hire and train qualified personnel. Also, the main U.S. manufacturing facilities are unionized, so any labor disruption could have a significant impact on Power Transmission’s ability to maintain production levels. The current labor contract expires in October 2011.

Markets:

Power Transmission services many diverse markets, with high-speed gearing for markets such as petrochemicals, refineries, offshore production and transmission of oil and low-speed gearing for the gas, rubber, sugar, paper, steel, plastics, mining, cement and marine propulsion markets, each of which has its own unique set of drivers. Favorable conditions for one market may be unfavorable for another market. Generally, if general global industrial capacity utilizations are not high, spending on new equipment lags. Also impacting demand are government regulations involving safety and environmental issues that can require capital spending. Recent market demand increases have come from energy-related markets such as refining, petrochemical, drilling, coal, marine and power generation in response to higher global energy prices. RMT products generally follow the market for high-speed gearboxes. During the latter part of 2008, energy prices decreased significantly, global growth slowed and large project financing became difficult to secure. New order booking declined in the first half of 2009, which negatively impacted sales starting in late 2009. Order levels increased in the first half of 2010 as energy markets recovered, translating into higher sales in the second half of 2010. The pace of bookings in 2011 is expected to remain at this higher level, which should translate in to overall higher sales in 2011 compared to 2010.

Competition:

Despite the highly technical nature of the products in this segment, there are many competitors. While several North American competitors have de-emphasized the market, many European companies remain in the market. Competitors include Flender Graffenstaden, BHS, Renk, Rientjes, CMD, Philadelphia Gear and Horsburgh & Scott. While price is an important factor, proven designs, workmanship and engineering support are critical factors. Due to this, the Company outsources very little of the design and manufacturing processes.

Federal Regulation and Environmental Matters

The Company’s operations are subject to various federal, state and local laws and regulations, including those related to air emissions, wastewater discharges, the handling of solid and hazardous wastes and occupational safety and health. Environmental laws have, in recent years, become more stringent and have generally sought to impose greater liability on a larger number of potentially responsible parties. While the Company is not currently aware of any situation involving an environmental claim that would likely have a material adverse effect on its business, it is always possible that an environmental claim with respect to one or more of the Company’s current businesses or a business or property that one of our predecessors owned or used could arise that could have a material adverse effect. The Company’s operations have incurred, and will continue to incur, capital and operating expenditures and other costs in complying with these laws and regulations in both the United States and abroad. However, the Company does not anticipate the future costs of environmental compliance will have a material adverse effect on its business, financial results or results of operations.

Item 1A. Risk Factors.

The risks described below are those which the Company believes are the material risks that it faces. Any of the risk factors described below could significantly and adversely affect its business, prospects, financial condition and results of operations.

A decline in domestic and worldwide oil and gas drilling activity would adversely affect the Company’s results of operations.

The Oil Field segment is materially dependent on the level of oil and gas drilling activity in North America and worldwide, which in turn depends on the level of capital spending by major, independent and state-owned exploration and production companies. This capital spending is driven by current prices for oil and gas and the perceived stability and sustainability of those prices. Oil and gas prices have been subject to significant fluctuation in recent years in response to changes in the supply and demand for oil and gas, market uncertainty, world events, governmental actions, and a variety of additional factors that are beyond the Company’s control, including:

·	the level of North American and worldwide oil and gas exploration and production activity;

·	worldwide economic conditions, particularly economic conditions in North America;

·	oil and gas production costs;

·	weather conditions;

·	the expected costs of developing new reserves;

·	national government political requirements and the policies of OPEC;

·	the price and availability of alternative fuels;

·	the effect of worldwide energy conservation measures;

·	environmental regulation; and

·	tax policies.

Increases in the prices of our raw materials could adversely affect the Company’s margins and results of operations.

The Company uses large amounts of steel, iron and electricity in the manufacture of its products. The price of these raw materials has a significant impact on the cost of producing products. Steel and electricity prices have increased significantly in the last five years, caused primarily by higher energy prices and increased global demand. Since most of the Company’s suppliers are not currently parties to long-term contracts with us, the Company is vulnerable to fluctuations in prices of such raw materials. Factors such as supply and demand, freight costs and transportation availability, inventory levels of brokers and dealers, the level of imports and general economic conditions may affect the price of cast iron and steel. Raw material prices may increase significantly in the future. Certain items such as steel round, bearings and aluminum have continued to experience price increases, price volatility and longer lead times. If the Company is unable to pass future raw material price increases on to its customers, margins, results of operations, cash flow and financial condition could be adversely affected.

Interruption in the Company’s supply of raw materials could adversely affect its results of operations.

The Company relies on various suppliers to supply the components utilized to manufacture its products. The availability of the raw materials is not only a function of the availability of steel and iron, but also the alloy materials that are utilized by the Company’s suppliers. To date, these shortages have not caused a material disruption in availability or the Company’s manufacturing operations. However, material disruptions may occur in the future. Raw material shortages and allocations may result in inefficient operations and a build-up of inventory, which can negatively affect the Company’s working capital position. The loss of any of the Company’s suppliers or their inability to meet its price, quality, quantity and delivery requirements could have an adverse effect on the Company’s business and results of operations.

The inherent dangers and complexity of the Company’s products and services could subject it to substantial liability claims that may not be covered by insurance and that could adversely affect our results of operations.

The products that the Company manufactures and the services that it provides are complex, and the failure of this equipment to operate properly or to meet specifications may greatly increase customers’ costs. In addition, many of these products are used in inherently hazardous industries, such as the oil and gas drilling and production industry where an accident or product failure can cause personal injury or loss of life, damage to property, equipment, or the environment, regulatory investigations and penalties and the suspension of the end-user’s operations. If the Company’s products or services fail to meet specifications or are involved in accidents or failures, the Company could face warranty, contract, or other litigation claims for which it may be held responsible and its reputation for providing quality products may suffer.

The Company’s insurance may not be adequate in risk coverage or policy limits to cover all losses or liabilities that the Company may incur or for which the Company may be found responsible. Moreover, in the future, the Company may not be able to maintain insurance at levels of risk coverage or policy limits that it deems adequate or at premiums that it deems reasonable, particularly in the recent environment of significant insurance premium increases. Further, any claims made under the Company’s policies will likely cause its premiums to increase.

Any future damages deemed to be caused by the Company’s products or services that are assessed against it and that are not covered by insurance, or that are in excess of policy limits or subject to substantial deductibles, could have a material adverse effect on the Company’s results of operations and financial condition. Litigation and claims for which the Company is not insured can occur, including employee claims, intellectual property claims, breach of contract claims, and warranty claims.

The Company may not be able to successfully integrate future acquisitions, which will cause it to fail to realize expected returns.

The Company continually explores opportunities to acquire related businesses, some of which could be material to the Company. The ability to continue to grow, however, may depend upon identifying and successfully acquiring attractive companies, effectively integrating these companies, achieving cost efficiencies and managing these businesses as part of the Company. The Company may not be able to effectively integrate the acquired companies and successfully implement appropriate operational, financial and management systems and controls to achieve the benefits expected to result from these acquisitions. The Company’s efforts to integrate these businesses could be affected by a number of factors beyond its control, such as regulatory developments, general economic conditions and increased competition. In addition, the process of integrating these businesses could cause the interruption of, or loss of momentum in, the activities of the Company’s existing business. The diversion of management’s attention and any delays or difficulties encountered in connection with the integration of these businesses could negatively impact the Company’s business and results of operations. Further, the benefits that the Company anticipates from these acquisitions may not develop.

Labor dispute or the expiration of the Company’s current labor contract could have a material adverse effect on its business.

The Company’s main U.S. manufacturing facilities are unionized and the current labor contract with respect to those facilities expires in October 2011. The Company cannot assure that any disputes, work stoppages or strikes will not arise in the future. In addition, when the existing collective bargaining agreement expires, the Company cannot assure that it will be able to reach a new agreement with its employees or that any new agreement will be on substantially similar terms as the existing agreement. Future disputes with and labor concessions to the Company’s employees could have a material adverse effect upon its results of operations and financial position.

The inability to hire and retain qualified employees may hinder the Company’s growth.

The ability to provide high-quality products and services depends in part on the Company’s ability to hire and retain skilled personnel in the areas of management, product engineering, servicing and sales. Competition for such personnel is intense and competitors can be expected to attempt to hire the Company’s skilled employees from time to time. In particular, the Company’s business and results of operations could be materially adversely affected if it is unable to retain the customer relationships and technical expertise provided by the Company’s management team and professional personnel.

Significant competition in the industries in which the Company operates may result in its competitors offering new or better products and services or lower prices, which could result in a loss of customers and a decrease in revenues.

The industries in which the Company operates are highly competitive. The Company competes with other manufacturers and service providers of varying sizes, some of which may have greater financial and technological resources than it does. If the Company is unable to compete successfully with other manufacturers and service providers, it could lose customers and its revenues may decline. In addition, competitive pressures in the industry may affect the market prices of the Company’s new and used equipment, which, in turn, may adversely affect its sales margins, results of operations, cash flow and financial condition.

Disruption of the Company’s manufacturing operations or management information systems would have an adverse effect on its financial condition and results of operations.

While the Company owns numerous facilities domestically and internationally, its primary manufacturing facilities, located in and around Lufkin, Texas account for a significant percentage of its manufacturing output. An unexpected disruption in the Company’s production at these facilities or in its management information systems for any length of time would have an adverse effect on our business, financial condition and results of operations.

The Company has foreign operations that would be adversely impacted in the event of war, political disruption, civil disturbance, economic and legal sanctions and changes in global trade policies.

The Company has operations in certain international areas, including parts of the Middle East and South America, that are subject to risks of war, political disruption, civil disturbance, economic and legal sanctions (such as restrictions against countries that the U.S. government may deem to sponsor terrorism) and changes in global trade policies. The Company’s operations may be restricted or prohibited in any country in which these risks occur. In particular, the occurrence of any of these risks could result in the following events, which in turn, could materially and adversely impact the Company’s results of operations:

·	disruption of oil and natural gas exploration and production activities;

·	restriction of the movement and exchange of funds;

·	inhibition of our ability to collect receivables;

·	enactment of additional or stricter U.S. government or international sanctions; and

·	limitation of our access to markets for periods of time.

Results of operations could be adversely affected by actions under U.S. trade laws.

Although the Company is a U.S.-based manufacturing and services company, it owns and operates international manufacturing operations that support its U.S.-based business. If actions under U.S. trade laws were instituted that limited the Company’s access to these products, the Company’s ability to meet its customer specifications and delivery requirements would be reduced. Any adverse effects on the Company’s ability to import products from its foreign subsidiaries could have a material adverse effect on its results of operations.

The Company is subject to currency exchange rate risk, which could adversely affect its results of operations.

The Company is subject to currency exchange rate risk with intercompany debt denominated in U.S. dollars owed by its Canadian subsidiary. The Company cannot assure that future currency exchange rate fluctuations will not have an adverse affect on its results of operations.

Significant changes in pension fund investment performance or assumptions relating to pension costs may have a material effect on the valuation of pension obligations, the funded status of pension plans, and the Company’s pension cost.

The Company’s funding policy for its pension plan is to accumulate plan assets that, over the long-run, will approximate the present value of projected benefit obligations. The Company’s pension cost is materially affected by the discount rate used to measure pension obligations, the level of plan assets available to fund those obligations at the measurement date and the expected long-term rate of return on plan assets. The Company’s pension plan is supported by pension fund investments that are volatile and subject to financial market risk, including fixed income, domestic and foreign equity securities, real estate and hedge funds. Significant changes in investment performance or a change in the portfolio mix of invested assets could result in corresponding increases and decreases in the valuation of plan assets or in a change of the expected rate of return on plan assets. A change in the discount rate would result in a significant increase or decrease in the valuation of pension obligations, affecting the reported funded status of the Company’s pension plans as well as the net periodic pension cost in the following fiscal years. Similarly, changes in the expected return on plan assets could result in significant changes in the net periodic pension cost for subsequent fiscal years.

The Company’s common stock has experienced, and may continue to experience, price volatility.

The trading price of the Company’s common stock has been and may continue to be subject to large fluctuations. The Company’s common stock price may increase or decrease in response to a number of events and factors, including:

·	trends in the Company’s industries and the markets in which it operates;

·	changes in the market price of the products the Company sells;

·	the introduction of new technologies or products by the Company or its competitors;

·	changes in expectations as to the Company’s future financial performance, including financial estimates by securities analysts and investors;

·	operating results that vary from the expectations of securities analysts and investors;

·	announcements by the Company or its competitors of significant contracts, acquisitions, strategic partnerships, joint ventures, financings or capital commitments;

·	the price of oil;

·	changes in laws and regulations; and

·	general economic and competitive conditions.

Due to the recent financial and credit crisis, certain of the Company’s counterparties may be unable to meet their financial obligations to the Company or, alternatively, may be forced to postpone or otherwise cancel their contracts with the Company.

The recent credit crisis and the related turmoil in the global financial system have had an adverse impact on the Company’s business and financial condition and the business and financial condition of our counterparties. While the financial markets experienced improvement in 2010, the Company may face challenges if conditions in the financial markets do not continue to improve in 2011. The Company may be subject to increased counterparty risks whereby its counterparties may not be willing or able to meet their financial obligations to the Company or, alternatively, may be forced to postpone or otherwise cancel their contracts with the Company. To the extent a third-party is unable to meet its obligations to the Company, the earnings and results of operations of the Company could be negatively impacted in future reporting periods. A sustained decline in the ability of the Company’s counterparties to meet their financial obligations to the Company would adversely affect its business, results of operations and financial condition.

Climate change legislation limiting and reducing greenhouse gas emissions through a “cap and trade” system of allowances and credits could result in increased operating costs and reduced demand for our products or services.

On June 26, 2009, the U.S. House of Representatives passed the American Clean Energy and Security Act of 2009, which would establish an economy-wide cap-and-trade program to reduce U.S. emissions of greenhouse gases, including carbon dioxide and methane. Although it is not possible at this time to predict if or when any future federal laws or implementing regulations addressing greenhouse gas emissions may be adopted, and such laws or regulations that may be adopted could require the Company to incur increased operating costs, could adversely impact customers’ operations or demand for customers’ products, or could adversely affect demand for the Company’s products or services.

An array of international climate change accords focused on limiting and reducing greenhouse gas emissions could result in increased operating costs and reduced demand for our products or services.

The Company services customers in numerous foreign countries. As such, we are subject not only to U.S. climate change legislation but may also be subject to certain international climate change accords. A variety of regulatory developments, proposals or requirements have been introduced and/or adopted in the international regions in which we operate that are focused on restricting the emission of carbon dioxide, methane and other greenhouse gases. Among these developments are the United Nations Framework Convention on Climate Change, also known as the “Kyoto Protocol, ” and the European Union Emissions Trading System (“EU ETS”), which was launched as an international “cap and trade” system on allowances for emitting greenhouse gases. These international regulatory developments may curtail production and demand for fossil fuels such as oil and gas in areas of the world where the Company and our customers operate and thus adversely affect future demand for the Company’s products and services, which may in turn adversely affect the Company’s future results of operations.

Climate change regulations restricting emissions of greenhouse gases could result in increased operating costs and reduced demand for our products or services.

On December 15, 2009, the U.S. Environmental Protection Agency (the “EPA”) officially published its findings that emissions of carbon dioxide, methane and other greenhouse gases present an endangerment to human health and the environment because emissions of such gases are, according to the EPA, contributing to warming of the Earth’s atmosphere and other climatic changes. These findings by the EPA allow the agency to proceed with the adoption and implementation of regulations that would restrict emissions of greenhouse gases under existing provisions of the federal Clean Air Act. In response to its endangerment findings, the EPA adopted regulations that require a reduction in emissions of greenhouse gases from motor vehicles. The EPA has asserted that the motor vehicle greenhouse gas emissions standards triggered the Clean Air Act construction and operating permit requirements for stationary sources, commencing when the motor vehicle standards took effect on January 2, 2011. The EPA also adopted rules which will lead to the imposition of greenhouse gas emission limitations in Clean Air Act permits for certain stationary sources. In addition, on September 22, 2009, the EPA issued a final rule requiring the reporting of greenhouse gas emissions from specified large greenhouse gas emission sources in the United States beginning in 2011 for emissions occurring in 2010. The adoption and implementation of any regulations imposing reporting obligations on, or limiting emissions of greenhouse gases from, our equipment and operations could require the Company to incur costs to reduce emissions of greenhouse gases associated with operations, could adversely impact customers’ operations or demand for customers’ products, or could adversely affect demand for the Company’s products or services.

Item 3. Legal Proceedings

On March 7, 1997, a class action complaint was filed against Lufkin Industries, Inc. (the “Company”) in the U.S. District Court for the Eastern District of Texas by an employee and a former employee of the Company who alleged race discrimination in employment. Certification hearings were conducted in Beaumont, Texas in February 1998 and in Lufkin, Texas in August 1998. In April 1999, the District Court issued a decision that certified a class for this case, which included all black employees employed by the Company from March 6, 1994, to the present. The case was administratively closed from 2001 to 2003 while the parties unsuccessfully attempted mediation. Trial for this case began in December 2003, and after the close of plaintiff’s evidence, the court adjourned and did not complete the trial until October 2004. Although plaintiff’s class certification encompassed a wide variety of employment practices, plaintiffs presented only disparate impact claims relating to discrimination in initial assignments and promotions at trial.

On January 13, 2005, the District Court entered its decision finding that the Company discriminated against African-American employees in initial assignments and promotions. The District Court also concluded that the discrimination resulted in a shortfall in income for those employees and ordered that the Company pay those employees back pay to remedy such shortfall, together with pre-judgment interest in the amount of 5%. On August 29, 2005, the District Court determined that the back pay award for the class of affected employees was $3.4 million (including interest to January 1, 2005) and provided a formula for attorney fees that the Company estimates will result in a total not to exceed $2.5 million. In addition to back pay with interest, the District Court (i) enjoined and ordered the Company to cease and desist all racially biased assignment and promotion practices and (ii) ordered the Company to pay court costs and expenses.

The Company reviewed this decision with its outside counsel and on September 19, 2005, appealed the decision to the U.S. Court of Appeals for the Fifth Circuit. On April 3, 2007, the Company appeared before the appellate court in New Orleans for oral argument in this case. The appellate court subsequently issued a decision on Friday, February 29, 2008 that reversed and vacated the plaintiff’s claim regarding the initial assignment of black employees into the Foundry Division. The court also denied plaintiff’s appeal for class certification of a class disparate treatment claim. Plaintiff’s claim on the issue of the Company’s promotional practices was affirmed but the back pay award was vacated and remanded for recomputation in accordance with the opinion. The District Court’s injunction was vacated and remanded with instructions to enter appropriate and specific injunctive relief. Finally, the issue of plaintiff’s attorney’s fees was remanded to the District Court for further consideration in accordance with prevailing authority.

On December 5, 2008, the U.S. District Court Judge Clark held a hearing in Beaumont, Texas during which he reviewed the 5 th U.S. Circuit Court of Appeals class action decision and informed the parties that he intended to implement the decision in order to conclude this litigation. At the conclusion of the hearing Judge Clark ordered the parties to submit positions regarding the issues of attorney fees, a damage award and injunctive relief. Subsequently, the Company reviewed the plaintiff’s submissions which described the formula and underlying assumptions that supported their positions on attorney fees and damages. After careful review of the plaintiff’s submission to the court the Company continued to have significant differences regarding legal issues that materially impacted the plaintiff’s requests. As a result of these different results, the court requested further evidence from the parties regarding their positions in order to render a final decision. The judge reviewed both parties arguments regarding legal fees, and awarded the plaintiffs an interim fee, but at a reduced level from the plaintiffs original request. The Company and the plaintiffs reconciled the majority of the differences and the damage calculations which also lowered the originally requested amounts of the plaintiffs on those matters. Due to the resolution of certain legal proceedings on damages during first half of 2009 and the District Court awarding the plaintiffs an interim award of attorney fees and cost totaling $5.8 million, the Company recorded an additional provision of $5.0 million in the first half of 2009 above the $6.0 million recorded in fourth quarter of 2008. The plaintiffs filed an appeal of the District Court’s interim award of attorney fees with the U.S. Fifth Circuit Court of Appeals. The Fifth Circuit subsequently dismissed these appeals on August 28, 2009 on the basis that an appealable final judgment in this case had not been issued. The court commented that this issue can be reviewed with an appeal of final judgment.

On January 15, 2010, the U.S. District Court for the Eastern District of Texas notified the Company that it had entered a final judgment related to the Company’s ongoing class-action lawsuit. On January 15, 2010, the plaintiffs filed a notice of appeal with the U.S. Fifth Circuit Court of Appeals of the District Court’s final judgment. On January 21, 2010, the Company filed a notice of cross-appeal with the same court.

On January 15, 2010, in its final judgment, the Court ordered Lufkin Industries to pay the plaintiffs $3.3 million in damages, $2.2 million in pre-judgment interest and 0.41% interest for any post-judgment interest. The Company had previously estimated the total liability for damages and interest to be approximately $5.2 million. The Court also ordered the plaintiffs to submit a request for legal fees and expenses from January 1, 2009 through the date of the final judgment. The plaintiffs were required to submit this request within 14 days of the final judgment. On January 21, 2010, the Company filed a motion with the District Court to stay the payment of damages referenced in the District Court’s final judgment pending the outcome of the Fifth Circuit’s decision on both parties’ appeals. The District Court granted this motion to stay.

On January 29, 2010, the plaintiffs filed a motion with the U.S. District Court for the Eastern District of Texas for a supplemental award of $0.7 million for attorney’s fees, costs and expenses incurred between January 1, 2009 and January 15, 2010, as allowed in the final judgment. In the fourth quarter of 2009, the Company recorded a provision of $1.0 million for these legal expenses and accrual adjustments for the final judgment award of damages. On September 28, 2010, the District Court granted plaintiffs’ motion for supplemental attorney’s fees, costs and expenses in the amount of $0.7 million for the period of January 1, 2009 through January 15, 2010. In order to cover these cost, the Company recorded an additional provision of $1.0 million in September 2010 for anticipated costs through the end of 2010.

On February 2, 2011 the United States Fifth Circuit Court of Appeals accepted the oral arguments from the plaintiffs and the Company on their respective appeals to the court. We anticipate the court’s decision before the end of the second quarter of 2011.

There are various other claims and legal proceedings arising in the ordinary course of business pending against or involving the Company wherein monetary damages are sought. For certain of these claims, the Company maintains insurance coverage while retaining a portion of the losses that occur through the use of deductibles and retention limits. Amounts in excess of the self-insured retention levels are fully insured to limits believed appropriate for the Company’s operations. Self-insurance accruals are based on claims filed and an estimate for claims incurred but not reported. While the Company does maintain insurance above its self-insured levels, a decline in the financial condition of its insurer, while not currently anticipated, could result in the Company recording additional liabilities. It is management’s opinion that the Company’s liability under such circumstances or involving any other non-insured claims or legal proceedings would not materially affect its consolidated financial position, results of operations, or cash flow.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

Overview

General

Lufkin Industries is a global supplier of oil field and power transmission products. Through its Oil Field segment, the Company manufactures and services artificial lift equipment and related products, which are used to extract crude oil and other fluids from wells. Through its Power Transmission segment, the Company manufactures and services high-speed and low-speed increasing and reducing gearboxes for industrial applications. While these markets are price-competitive, technological and quality differences can provide product differentiation.

The Company’s strategy is to differentiate its products through additional value-added capabilities. Examples of these capabilities are high-quality engineering, customized designs, rapid manufacturing response to demand through plant capacity, inventory and vertical integration, superior quality and customer service, and an international network of service locations. In addition, the Company’s strategy is to maintain a low debt-to-equity ratio in order to quickly take advantage of growth opportunities and pay dividends even during unfavorable business cycles.

In support of its strategy, the Company has made capital investments in the Oil Field segment to increase manufacturing capacity and capabilities in its two main manufacturing facilities in Lufkin, Texas and Argentina. These investments have reduced production lead times, improved quality and reduced manufacturing costs. Investments also continue to be made to expand the Company’s presence in automation products and international service. During the first quarter of 2009, the Company purchased International Lift Systems (“ILS”), which manufactures and services gas lift, plunger lift and completion equipment for the oil and gas industry and in November 2010 acquired the assets of Petro Hydraulic Lift Systems, which manufactured hydraulic pumping units. In July 2010, the Company announced its intention to construct a new multi-purpose manufacturing and aftermarket facility in Ploiesti Romania to support market expansion efforts in the Eastern Hemisphere. This facility will manufacture products for both the Oil Field and Power Transmission segments, with an initial focus on oil field products. This facility, which is being built on an 82 acre site, will have an estimated aggregate gross cost of $126 million. When completed in 2012, the facility will initially employ just over 300 employees. The government of Romania, through the Ministry of Public Finance, has agreed to provide the Company with economic development incentives and financial assistance of 28 million Euros towards the construction costs, which accounts for approximately 30% of the total cost of the plant. The Company continues to look for investment opportunities to reduce manufacturing costs, expand geographically and add product offerings in the artificial lift space. On November 1, 2010 the Company completed the acquisition of the significant operating assets of Petro Hydraulic Lift Systems, LLC (“PHL”) and certain related companies, based in South Louisiana. PHL, specializes in the design, manufacture and leasing of hydraulic rod pumping units for oil and gas wells.

In the Power Transmission segment, the Company continues to expand its gear repair network by opening and expanding facilities in various locations in the United States and Canada. The Company has made targeted capital investments in the United States and France to expand capacity, develop new product lines and reduce manufacturing lead times, in addition to certain capital investments targeting cost reductions. On July 1, 2009, the Company purchased Rotating Machinery Technology, Inc. (“RMT”), which specializes in the analysis, design and manufacture of precision, custom-engineered tilting-pad bearings and related components for high-speed turbo equipment operating in critical duty applications. RMT also services, repairs and upgrades turbo-expander process units for air and gas separation, both on-site with its skilled field service team and at its repair facility in Wellsville, New York. The Company intends to focus future capital investments for Oil Field and Power Transmission on international geographic expansion of manufacturing and service centers.

Trends/Outlook

Oil Field

Demand for the Company’s artificial lift equipment is primarily dependent on the level of new onshore oil wells, workover drilling activity, the depth and fluid conditions of such drilling activity and general field maintenance budgets. Drilling activity is driven by the available cash flow of the Company’s customers as well as their long-term perceptions of the level and stability of the price of oil. Increasing energy prices since 2004 increased the demand for pumping units and related service and products as a result of higher drilling activity, activation of idle wells and the upgrading of existing wells. In the fourth quarter of 2008, energy prices dramatically declined due to reductions in global demand. Planned new drilling and workover activity also reduced significantly as capital and operating budgets were reduced. These negative trends continued into the first quarter of 2009, and worsened during the second quarter of 2009, as E&P companies deferred or cancelled drilling programs and reduced field spending in response to lower energy prices. This trend was more pronounced in North America than in international markets. Lower selling prices combined with the negative impact of low capacity utilization in manufacturing facilities caused gross margins to decline in 2009. In the second half of 2009, oil prices increased back to 2007 levels and drilling activity, especially for oil, increased.

During 2010, demand from North America increased steadily as the oil-directed rig count level surpassed 2008 levels. North America demand for artificial lift equipment has not increased as quickly as the oil-directed rig count due to fewer well completions per rig drilling due to the increased use of multi-stage horizontal frac technology, delays in completions due to unavailability of frac crews and improvements in drilling technology that extends the length of time wells remain free-flowing. Also, while order levels have continued to increase during 2010, the ability to raise prices remains a challenge. Most raw material prices have remained stable during 2010, but certain raw material associated with cast iron have recently increased. The Company expects 2011 demand to continue to increase over 2010 levels as these market issues are resolved and equipment sales start to catch up to the prior oil-directed rig count increases.

While the oil market is cyclical, the Company continues to believe that there are long-term positive growth trends for artificial lift equipment, and as existing fields mature, the market will require an increased use of artificial lift, especially in the South American, European, Russian and Middle Eastern markets. For this reason, the Company announced its intentions to construct a new multi-purpose manufacturing and aftermarket facility in Romania to support these markets. The new facility will be operational in 2012 and will cost approximately $90 million net after Romanian government economic incentives. Additionally, the acquisitions of ILS and PHL were consistent with the Company’s long-term growth strategy of integrating strategic assets to leverage the Company’s position of industry leadership, providing an entry for Lufkin into the offshore market for artificial lift wells, including deepwater plays, and expanded reach into the artificial lift market.

Power Transmission

Power Transmission services many diverse markets, with high-speed gearing for markets such as petrochemicals, refineries, offshore production and transmission of oil and slow-speed gearing for the gas, rubber, sugar, paper, steel, plastics, mining, cement and marine propulsion markets, each of which has its own unique set of drivers. Generally, if global industrial capacity utilizations are not high, spending on new equipment lags. Also impacting demand are government regulations involving safety and environmental issues that can require capital spending. Recent market demand increases have come from energy-related markets such as refining, petrochemical, drilling, coal, marine and power generation in response to higher global energy prices. During the latter part of 2008, energy prices decreased significantly, global growth slowed and large project financing became difficult to secure. New order booking declined in the first half of 2009, which negatively impacted sales starting in late 2009. While sales remained at these lower levels throughout the first half of 2010, new order and quotation activity, especially from the energy markets, increased during 2010 over levels seen in 2009. The pace of bookings in 2011 is expected to remain at this higher level, which should translate in to overall higher sales in 2011 compared to 2010.

Discontinued Operations

During the second quarter of 2008, the Trailer segment was classified as a discontinued operation. In January 2008, the Company announced the decision to suspend its participation in the commercial trailer markets and to develop a plan to run-out existing inventories, fulfill contractual obligations and close all trailer facilities. During the second quarter of 2008, this plan was completed, with the majority of the remaining inventory and manufacturing equipment sold and all facilities closed.

Other

During 2010, 2009 and 2008, the Company booked pre-tax contingent liability provisions of $1.0 million, $6.0 million and $6.0 million, respectively, for its ongoing class-action lawsuit. For additional information, please see Part I, Item 3 “Legal Proceedings” of this annual report on Form 10-K.

Summary of Results

The Company generally monitors its performance through analysis of sales, gross margin (gross profit as a percentage of sales) and net earnings, as well as debt/equity levels, short-term debt levels, and cash balances.

Overall, sales for 2010 increased to $645.6 million from $521.4 million for 2009, or 23.8%. This increase in 2010 was primarily driven by higher sales of Oil Field products and services in the North American markets. In 2008, sales were $741.2 million.

Gross margin for 2010 increased to 24.6% from 21.6% for 2009, due primarily to the favorable impact of higher plant utilization on fixed cost coverage in the Oil Field segment. Gross margin in 2008 was 28.9%. Additional segment data on gross margin is provided later in this section.

Higher selling, general and administrative expenses negatively impacted net earnings, with these expenses increasing to $89.9 million during 2010 from $75.1 million during 2009 and $72.0 million during 2008. This increase in 2010 was primarily related to resources added from the ILS and RMT acquisitions, higher employee-related expenses in support of international expansion efforts and new product development. As a percentage of sales, selling, general and administrative expenses decreased to 13.9% during 2010 compared to 14.4% during 2009, but increased compared to 9.7% during 2008. Operating income was also impacted by a litigation reserve of $1.0 million during 2010, as compared to $6.0 million each during 2008 and 2009, related to its ongoing class-action lawsuit.

The Company reported net earnings from continuing operations of $43.5 million, or $1.44 per share (diluted), for 2010, compared to net earnings from continuing operations of $22.5 million, or $0.76 per share (diluted), for 2009, and net earnings from continuing operations of $88.0 million, or $2.96 per share (diluted), for 2008.

Debt/equity (long-term debt net of current portion as a percentage of total equity) levels were back to 0.0% as of December 31, 2010 from 0.3% as of December 31, 2009. Cash balances at December 31, 2010, were $88.6 million, down from $100.9 million at December 31, 2009.

Oil Field

Oil Field sales increased to $477.9 million, or by 36.9%, for the year ended December 31, 2010, from $349.2 million for the year ended December 31, 2009. New pumping unit sales of $254.4 million during 2010 were up $66.2 million, or 35.2%, compared to $188.2 million during 2009, primarily from higher U.S. demand. Pumping unit service sales of $104.1 million during 2010 were up $19.2 million, or 22.6%, compared to $84.9 million during 2009. Automation sales of $83.8 million during 2010 were up $32.4 million, or 62.9%, compared to $51.4 million during 2008. Commercial casting sales of $11.3 million during 2010 were up $1.9 million, or 20.4%, compared to $9.3 million during 2009. Sales from Lufkin ILS of $24.4 million during 2010 were up $9.1 million, or 62.9%, compared to $15.3 million in 2009, which represents 10 months of operations. Oil Field’s backlog increased to $131.4 million as of December 31, 2010, from $43.3 million at December 31, 2009. This increase was caused primarily by higher orders for new pumping units as U.S. and international customers increased production due to higher oil prices.

Gross margin (gross profit as a percentage of sales) for the Oil Field segment increased to 23.5% for year ended December 31, 2010, compared to 18.8% for the year ended December 31, 2009, or 4.7 percentage points. This gross margin increase was related to the positive impact of higher plant utilization on fixed cost coverage.

Direct selling, general and administrative expenses for Oil Field increased to $36.7 million, or by 37.4%, for the year ended December 31, 2010, from $26.7 million for the year ended December 31, 2009. This increase was due to higher employee-related and legal expenses. Direct selling, general and administrative expenses as a percentage of sales increased only 0.1% to 7.7% for the year ended December 31, 2010, from 7.6% for the year ended December 31, 2008.

Power Transmission

Sales for the Company’s Power Transmission segment decreased to $167.8 million, or by 2.6%, for the year ended December 31, 2010, compared to $172.2 million for the year ended December 31, 2009. New unit sales of $114.2 million during 2010 were down $17.6 million, or 13.3%, compared to $131.8 million during 2009. Repair and service sales of $48.8 million during 2010 were up $10.5 million, or 27.3%, compared to $38.4 million during 2009. Sales from Lufkin RMT increased to $4.7 million during 2010, up from $2.0 million during 2009. A portion of this increase is due to 2009 representing only 6 months of operations. Power Transmission backlog at December 31, 2010, increased to $101.6 million from $97.0 million at December 31, 2009, primarily from increased bookings of new units for the energy-related markets.

Gross margin for the Power Transmission segment increased to 27.6% for the year ended December 31, 2010, compared to 27.3% for the year ended December 31, 2009, or 0.3 percentage points. This gross margin increase was primarily from the favorable impact of higher production levels in manufacturing and repair on fixed cost coverage and an improved product mix.

Direct selling, general and administrative expenses for Power Transmission increased to $27.5 million, or by 17.0%, for the year ended December 31, 2010, compared to $23.5 million for the year ended December 31, 2009. Direct selling, general and administrative expenses as a percentage of sales increased to 16.4% for the year ended December 31, 2010, from 13.7% for the year ended December 31, 2009.

Corporate/Other

Corporate administrative expenses, which are allocated to the segments primarily based on budgeted sales levels, were $25.6 million for the year ended December 31, 2010, an increase of $0.7 million or 2.8%, from $24.9 million for the year ended December 31, 2009.

Interest income, interest expense and other income and expense for the year ended December 31, 2010, decreased to $.2 million of expense compared to $1.6 million of income for the year ended December 31, 2009, primarily from a decrease in gains of currency exchange and other interest from tax overpayments.

Pension expense, which is reported as a component of cost of sales, decreased to $7.9 million for the year ended December 31, 2010, compared to $10.7 million for the year ended December 31, 2009. This decrease in expense was primarily due to the impact of favorable demographic trends.

The net tax rate for the year ended December 31, 2010, was 35.5%, compared to 31.9% for the year ended December 31, 2009. The net tax rate in 2009 benefitted from adjustments to prior period tax filings in the U.S related to changes in tax laws.

Year Ended December 31, 2009 Compared to Year Ended December 31, 2008:

The following table summarizes the Company’s sales and gross profit by operating segment (in thousands of dollars):

					Increase/			% Increase/

*Due to the discontinuation of the Trailer segment, certain items previously allocated to that segment in cost of sales have been reclassified to continuing operations. The adjustment is related to pension and postretirement charges associated with Trailer personnel that will continue to be a liability in future years.

Oil Field

Oil Field sales decreased to $349.2 million, or by 36.7%, for the year ended December 31, 2009, from $551.8 million for the year ended December 31, 2008. New pumping unit sales of $188.2 million during 2009 were down $153.9 million, or 45.0%, compared to $342.1 million during 2008, primarily from lower U.S. demand and pricing pressure. Pumping unit service sales of $84.9 million during 2009 were down $18.1 million, or 17.6%, compared to $103.0 million during 2008, from declines in the U.S. market. Automation sales of $51.4 million during 2009 were down $30.9 million, or 37.5%, compared to $82.4 million during 2008, from lower sales in the U.S and pricing pressure. Commercial casting sales of $9.3 million during 2009 were down $15.1 million, or 61.6%, compared to $24.4 million during 2008, from lower sales to the machine tool market. Sales from Lufkin ILS contributed $15.3 million during 2009. Oil Field’s backlog decreased to $43.3 million as of December 31, 2009, from $188.1 million at December 31, 2008. This decrease was caused primarily by lower orders for new pumping units as U.S. and international customers deferred or cancelled drilling programs in response to lower energy prices.

Gross margin (gross profit as a percentage of sales) for the Oil Field segment decreased to 18.8% for year ended December 31, 2009, compared to 27.8% for the year ended December 31, 2008, or 9.0 percentage points. This gross margin decrease was related to price reductions in response to material price decreases and lower customer demand and the negative impact of lower plant utilization on fixed cost coverage.

Direct selling, general and administrative expenses for Oil Field increased to $26.7 million, or by 18.2%, for the year ended December 31, 2009, from $22.6 million for the year ended December 31, 2008. The majority of this increase is related to higher international sales commissions as well as the resources added with the ILS acquisition. Direct selling, general and administrative expenses as a percentage of sales increased to 7.6% for the year ended December 31, 2009, from 4.1% for the year ended December 31, 2008.

Power Transmission

Sales for the Company’s Power Transmission segment decreased to $172.2 million, or by 9.1%, for the year ended December 31, 2009, compared to $189.4 million for the year ended December 31, 2008. New unit sales of $131.8 million during 2009 were down $13.1 million, or 9.0%, compared to $144.9 million during 2008. Repair and service sales of $38.4 million during 2009 were down $6.1 million, or 13.7%, compared to $44.5 million during 2008 as customers deferred spending on maintenance projects due to poor economic conditions. Sales from Lufkin RMT contributed $2.0 million during 2009. Power Transmission backlog at December 31, 2009, decreased to $97.0 million from $129.3 million at December 31, 2008, primarily from decreased bookings of new units for the energy-related and marine markets.

Gross margin for the Power Transmission segment decreased to 27.3% for the year ended December 31, 2009, compared to 31.8% for the year ended December 31, 2008, or 4.5 percentage points. This gross margin decrease was primarily from the unfavorable impact of lower production levels in manufacturing and repair on fixed cost coverage.

Direct selling, general and administrative expenses for Power Transmission remained at $23.5 million for the year ended December 31, 2009, compared to the year ended December 31, 2008. However, direct selling, general and administrative expenses as a percentage of sales increased to 13.7% for the year ended December 31, 2009, from 12.4% for the year ended December 31, 2008.

Corporate/Other

Corporate administrative expenses, which are allocated to the segments primarily based on budgeted sales levels, were $24.9 million for the year ended December 31, 2009, a decrease of $1.0 million or 4.0%, from $25.9 million for the year ended December 31, 2008.

Interest income, interest expense and other income and expense for the year ended December 31, 2009, increased to $1.6 million of income compared to $0.3 million of income for the year ended December 31, 2008, from currency gains offsetting reduced interest income and increased interest expense.

Pension expense, which is reported as an increase in cost of sales, increased to $10.7 million for the year ended December 31, 2009, compared to pension income of $1.3 million for the year ended December 31, 2008. This expense increase was primarily due to lower expected returns on asset balances and the amortization of previously deferred market losses out of other comprehensive income.

The net tax rate for the year ended December 31, 2009, was 31.9%, compared to 35.5% for the year ended December 31, 2008. The net tax rate in 2009 benefitted from adjustments to prior period tax filings in the U.S., the settlement of the 2006 IRS tax audit, revised 199 manufacturing deduction claims and R&E tax credit estimate adjustments.

Liquidity and Capital Resources

The Company has historically relied on cash flows from operations and third-party borrowings to finance its operations, including acquisitions, dividend payments and stock repurchases. The Company believes that its cash flows from operations and its available borrowing capacity under its credit agreements will be sufficient to fund its operations, including planned capital expenditures, dividend payments and stock repurchases, through December 31, 2011, and the foreseeable future.

The Company’s cash balance totaled $88.6 million at December 31, 2010, compared to $100.9 million at December 31, 2009. For the year ended December 31, 2010, net cash provided by operating activities was $59.5 million, net cash used in investing activities totaled $69.5 million and net cash used in financing activities amounted to $2.3 million. Significant components of cash provided by operating activities included net earnings from continuing operations, adjusted for non-cash expenses, of $75.0 million, partially offset by an increase in working capital of $15.5 million. This working capital increase was primarily due to an increase in trade receivables and inventory balances of $35.0 million and $5.0 million, respectively, due to increased sales volumes during 2010, partially offset by an increase in accounts payable and accrued liabilities of $27.2 million. Net cash used in investing activities included net capital expenditures totaling $60.4 million and the ILS, RMT, and PHL acquisitions totaling $9.9 million. Capital expenditures in 2010 were primarily for new facilities to support geographical and product line expansions in the Oil Field and Power Transmission segments. Capital expenditures for 2011 are projected to increase over 2010 spending levels, primarily for the new Romanian manufacturing facility, other new manufacturing and service facilities to support geographical and product line expansions and equipment replacement for efficiency improvements in the Oil Field and Power Transmission segments and will be funded by operating cash flows. Significant components of net cash used by financing activities included dividend payments of $15.0 million, or $0.50, per share and debt repayments of $2.9 million. Proceeds from stock option exercises of $13.3 million partially offset financing cash outflows.

The Company has a three-year credit facility with a domestic bank (the “Bank Facility”) consisting of an unsecured revolving line of credit that provides up to $80.0 million of aggregate borrowing. This Bank Facility expires on December 31, 2013. Borrowings under the Bank Facility bear interest, at the Company’s option, at either the greater of (i) the prime rate, (ii) the base CD rate plus an applicable margin or (iii) the Federal Funds Effective Rate plus an applicable margin or the London Interbank Offered Rate plus an applicable margin, depending on certain ratios as defined in the Bank Facility. As of December 31, 2010, no debt was outstanding under the Bank Facility and the Company was in compliance with all financial covenants under the terms of the Bank Facility. Deducting outstanding letters of credit of $16.4 million, $63.6 million of borrowing capacity was available at December 31, 2010.

The following table summarizes the Company’s expected cash outflows from financial contracts and commitments as of December 31, 2010. Information on recurring purchases of materials for use in manufacturing and service operations has not been included. These amounts are not long-term in nature (less than six months) and are generally consistent from year to year.

Total	$	16,705	$	8,372	$	2,575	$	1,588	$	4,170

Since the Company has no significant tax loss carryforwards, the Company expects to make quarterly estimated tax payments in 2011 based on taxable income levels. Also, the Company has various qualified retirement plans for which the Company has committed a certain level of benefit. The Company expects to make contributions to its pension plans of $6.4 million and to its post-retirement health and life plans of approximately $0.5 million in 2011. Contribution levels to these plans after 2011 will depend on participation in the plans, possible plan changes, discount rates and actual rates of return on plan assets.

As discussed in Note 17 – “Business Segment Information” in the Notes to Consolidated Financial Statements, set forth in Part II, Item 8 of this Form 10-K, the Consolidated Balance Sheet at December 31, 2010 includes approximately $1.8 million of liabilities associated with uncertain tax positions in the jurisdictions in which the Company conducts business. Due to the uncertain and complex application of tax regulations, combined with the difficulty in predicting when tax audits throughout the world may be concluded, Lufkin cannot make reliable estimates of the timing of cash outflows relating to these liabilities.

Off-Balance Sheet Arrangements

None.

Recently Issued Accounting Pronouncements

In September 2009, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2009-13, Revenue Recognition (Topic 605): Multiple – Deliverable Revenue Arrangements – a consensus of the FASB Emerging Issues Task Force, which changes the accounting for certain revenue arrangements. The new requirements change the allocation methods used in determining how to account for multiple payment streams and will result in the ability to separately account for more deliverables, and potentially less revenue deferrals. Additionally, ASU 2009-13 requires enhanced disclosures in financial statements. ASU 2009-13 is effective for revenue arrangements entered into or materially modified in fiscal years beginning after June 15, 2010 on a prospective basis, with early application permitted. The Company is currently evaluating the impact ASU 2009-13 will have on our financial statements.

Management believes the impact of other recently issued guidance, which is not yet effective, will not have a material impact on the Company's consolidated financial statements upon adoption.

Critical Accounting Policies and Estimates

The discussion and analysis of financial condition and results of operations are based upon the Company’s consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. The Company evaluates its estimates on an ongoing basis, based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions. The Company believes the following critical accounting policies affect its more significant judgments and estimates used in preparation of its consolidated statements.

The Company extends credit to customers in the normal course of business. Management performs ongoing credit evaluations of our customers and adjusts credit limits based upon payment history and the customer’s current credit worthiness. An allowance for doubtful accounts has been established to provide for estimated losses on receivable collections. The balance of this allowance is determined by regular reviews of outstanding receivables and historical experience. As the financial condition of customers change, circumstances develop or additional information becomes available, adjustments to the allowance for doubtful accounts may be required.

Revenue is not recognized until it is realized or realizable and earned. The criteria to meet this guideline are: persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the price to the buyer is fixed or determinable and collectability is reasonably assured. In some cases, a customer is not able to take delivery of a completed product and requests that the Company store the product for a defined period of time. The Company will process a Bill-and-Hold invoice and recognize revenue at the time of the storage request if all of the following criteria are met:

l	The customer has accepted title and risk of loss;
l	The customer has provided a written purchase order for the product;
l	The customer, not the Company, requested the product to be stored and to be invoiced under a Bill-and-Hold arrangement. The customer must also provide the business purpose for the storage request;
l	The customer must provide a storage period and future shipping date;
l	The Company must not have retained any future performance obligations on the product;
l	The Company must segregate the stored product and not make it available to use on other orders; and
l	The product must be completed and ready for shipment.

The Company has made significant investments in inventory to service its customers. On a routine basis, the Company uses estimates in determining the level of reserves required to state inventory at the lower of cost or market. Management’s estimates are primarily influenced by market activity levels, production requirements, the physical condition of products and technological innovation. Changes in any of these factors may result in adjustments to the carrying value of inventory. Also, the Company accounts for a significant portion of its inventory under the last-in, first-out (LIFO) method. The LIFO reserve can be impacted by changes in the LIFO layers and by inflation index adjustments . Generally, annual increases in the inflation rate or the first-in, first-out (FIFO) value of inventory cause the value of the LIFO reserve to increase.

Long-lived assets held and used by the Company are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company assesses the recoverability of long-lived assets by determining whether the carrying value can be recovered through projected undiscounted cash flows, based on expected future operating results. Future adverse market conditions or poor operating results could result in the inability to recover the current carrying value and thereby possibly requiring an impairment charge in the future.

Goodwill acquired in connection with business combinations represent the excess of consideration over the fair value of net assets acquired. The Company performs impairment tests on the carrying value of goodwill at least annually or whenever events or changes in circumstances indicate the carrying value of goodwill may be greater than fair value, such as significant underperformance relative to historical or projected operating results and significant negative industry or economic trends. The Company’s fair value is primarily determined using discounted cash flows, which requires management to make judgments about future operating results, working capital requirements and capital spending levels. Changes in cash flow assumptions or other factors which negatively impact the fair value of the operations would influence the evaluation and may result in a determination that goodwill is impaired and a corresponding impairment charge.

The application of income tax law is inherently complex. The Company is required to determine if an income tax position meets the criteria of more-likely-than-not to be realized based on the merits of the position under tax laws, in order to recognize an income tax benefit. This requires the Company to make many assumptions and judgments regarding merits of income tax positions and the application of income tax law. Additionally, if a tax position meets the recognition criteria of more-likely-than-not the Company is required to make judgments and assumptions to measure the amount of the tax benefits to recognize based on the probability of the amount of tax benefits that would be realized if the tax position was challenged by the taxing authorities. Interpretations and guidance surrounding income tax laws and regulations change over time. As a consequence, changes in assumptions and judgments can materially affect amounts recognized in the consolidated financial statements.

Deferred tax assets and liabilities are recognized for the differences between the book basis and tax basis of the net assets of the Company. In providing for deferred taxes, management considers current tax regulations, estimates of future taxable income and available tax planning strategies. Changes in state, federal and foreign tax laws as well as changes in the financial position of the Company could also affect the carrying value of deferred tax assets and liabilities. If management estimates that it is more-likely-than-not some or all of any deferred tax assets will expire before realization or that the future deductibility may not occur, a valuation allowance would be recorded.

The Company is subject to claims and legal actions in the ordinary course of business. The Company maintains insurance coverage for various aspects of its businesses and operations. The Company retains a portion of the insured losses that occur through the use of deductibles. Management regularly reviews estimates of reported and unreported insured and non-insured claims and legal actions and provides for losses through reserves. As circumstances develop and additional information becomes available, adjustments to loss reserves may be required.

The Company sells certain of its products to customers with a product warranty that provides repairs at no cost to the customer or the issuance of credit to the customer. The length of the warranty term depends on the product being sold, but ranges from one year to five years. The Company accrues its estimated exposure to warranty claims based upon historical warranty claim costs as a percentage of sales multiplied by prior sales still under warranty at the end of any period. Management reviews these estimates on a regular basis and adjusts the warranty provisions as actual experience differs from historical estimates or other information becomes available.

The Company offers defined benefit plans and other benefits upon the retirement of its employees. Assets and liabilities associated with these benefits are calculated by third-party actuaries under the rules provided by various accounting standards, with certain estimates provided by management. These estimates include the discount rate, expected rate of return of assets and the rate of increase of compensation and health claims. On a regular basis, management reviews these estimates by comparing them to actual experience and those used by other companies. If a change in an estimate is made, the carrying value of these assets and liabilities may have to be adjusted. Assuming all other variables held constant, differences in the discount rate and expected long-term rate of return on plan assets within reasonably likely ranges would have had the following estimated impact on 2010 results:

	Pension			Other
(Thousands of dollars)	Benefits			Benefits

Discount rate

Forward-Looking Statements and Assumptions

This annual report on Form 10-K contains forward-looking statements and information, within the meaning of the Private Securities Litigation Reform Act of 1995, that are based on management’s beliefs as well as assumptions made by and information currently available to management. When used in this report, the words “will,” “anticipate,” “believe,” “estimate,” “expect,” “plan,” “schedule,” “could,” “may,” “might,” “should,” “project” or similar expressions are intended to identify forward-looking statements. Similarly, statements that describe the Company’s future plans, objectives or goals are also forward-looking statements. Undue reliance should not be placed on forward-looking statements. Such statements reflect the Company’s current views with respect to certain events and are subject to certain assumptions, risks and uncertainties, many of which are outside the control of the Company. These risks and uncertainties include, but are not limited to:

l	oil prices;
l	declines in domestic and worldwide oil and gas drilling;
l	capital spending levels of oil producers;
l	availability and prices for raw materials;
l	the inherent dangers and complexities of the Company’s operations;
l	uninsured judgments or a rise in insurance premiums;
l	the inability to effectively integrate acquisitions;
l	labor disruptions and increasing labor costs;
l	the availability of qualified and skilled labor;
l	disruption of the Company’s operating facilities or management information systems;
l	the impact on foreign operations of war, political disruption, civil disturbance, economic and legal sanctions and changes in global trade policies;
l	currency exchange rate fluctuations in the markets in which the Company operates;
l	changes in the laws, regulations, policies or other activities of governments, agencies and similar organizations where such actions may affect the production, licensing, distribution or sale of the Company’s products, the cost thereof or applicable tax rates;
l	costs related to legal and administrative proceedings, including adverse judgments against the Company if the Company fails to prevail in reversing such judgments; and
l	general industry, political and economic conditions in the markets where the Company’s procures materials, components and supplies for the production of the Company’s principal products or where the Company’s products are produced, distributed or sold.

These and other risks are described in greater detail in “Risk Factors” included elsewhere in this annual report on Form 10-K. All forward-looking statements attributable to the Company or persons acting on its behalf are expressly qualified in their entirety by these factors. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those anticipated, believed, estimated or expected. The Company undertakes no obligations to update or revise its forward-looking statements, whether as a result of new information, future events or otherwise.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

The Company’s financial instruments include cash, accounts receivable, accounts payable, invested funds and debt obligations. The book value of accounts receivable, short-term debt and accounts payable are considered to be representative of their fair market value because of the short maturity of these instruments. While the Company’s accounts receivable are concentrated with customers in the energy industry the Company performs credit evaluations on current and potential customers and adjusts credit limits as appropriate. In certain circumstances the Company will obtain collateral to mitigate higher credit risk.

The Company does not utilize financial or derivative instruments for trading purposes or to hedge exposures to interest rates, foreign currency rates or commodity prices. Due to the lack of current debt, the Company does not have any significant exposure to interest rate fluctuations. However, if the Company drew on its line of credit under its Bank Facility, the Company would have exposure since the interest rate is variable. In addition, the Company primarily invoices and purchases in the same currency as the functional currency of its operations, which minimizes exposure to currency rate fluctuations.

The Company uses large amounts of steel, iron and electricity in the manufacture of its products. The prices of these raw materials have a significant impact on the cost of producing products. Steel and electricity prices have increased significantly in the last five years, caused primarily by higher energy prices and increased global demand. Since the Company does not enter into long-term contracts with most of its suppliers, the Company is vulnerable to fluctuations in prices of such raw materials. Factors such as supply and demand, freight costs and transportation availability, inventory levels of brokers and dealers, the level of imports and general economic conditions may affect the price of cast iron and steel. Raw material prices may increase significantly in the future. Certain items such as steel round, bearings and aluminum have continued to experience price increases, price volatility and longer lead times. If the Company is unable to pass future raw material price increases on to its customers, margins, results of operations, cash flow and financial condition could be adversely affected.

The Company is exposed to currency fluctuations with intercompany debt denominated in U.S. dollars owed by its French and Canadian subsidiaries. As of December 31, 2010, this inter-company debt was comprised of a $0.3 million receivable and a $4.3 million payable from France and Canada, respectively. As of December 31, 2010, if the U.S. dollar strengthened by 10% over these currencies, the net income impact would be $0.3 million of expense and if the U.S. dollar weakened by 10% over these currencies, the net income impact would be $0.3 million of income. Also, certain assets and liabilities, primarily employee and tax related in Argentina, denominated in the local currency of foreign operations whose functional currency is the U.S. dollar are exposed to fluctuations in currency rates. As of December 31, 2010, if the U.S. dollar strengthened or weakened by 10% over these currencies, the net income and expense impact would be negligible.

Item 8. Financial Statements and Supplementary Data

Management’s Report on Internal Control over Financial Reporting

The management of Lufkin Industries, Inc. (the “Company”), is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) and Rule 15d-15(f) promulgated under the Securities Exchange Act of 1934, as amended). The Company’s management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2010. In making this assessment, the Company’s management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) in “Internal Control- Integrated Framework.”

Based on this assessment, management believes that, as of December 31, 2010, the Company’s internal control over financial reporting is effective based on those criteria.

The effectiveness of the Company’s internal control over financial reporting as of December 31, 2010, has been audited by Deloitte & Touche LLP, an independent registered accounting firm, as stated in their report which appears herein.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of Lufkin Industries, Inc.

Lufkin, Texas

We have audited the accompanying consolidated balance sheets of Lufkin Industries, Inc. and subsidiaries (the "Company") as of December 31, 2010 and 2009, and the related consolidated statements of earnings, stockholders' equity and comprehensive income, and cash flows for each of the three years in the period ended December 31, 2010. Our audits also included the financial statement schedule listed in the Index at Item 15. We also have audited the Company's internal control over financial reporting as of December 31, 2010, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company's management is responsible for these financial statements and financial statement schedule, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control over Financial Reporting at Item 8. Our responsibility is to express an opinion on these financial statements and financial statement schedule and an opinion on the Company's internal control over financial reporting based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

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

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Lufkin Industries, Inc. and subsidiaries as of December 31, 2010 and 2009, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2010, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, such financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein. Also, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2010, based on the criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission .

LUFKIN INDUSTRIES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) Corporate Organization and Summary of Significant Accounting Policies

Lufkin Industries, Inc. and its consolidated subsidiaries (collectively, the “Company”) manufacture and sell oil field pumping units and power transmission products throughout the world. The impact of subsequent events on these financial statements has been evaluated through the date of issuance.

Principles of consolidation: The consolidated financial statements include the accounts of Lufkin Industries, Inc. and its wholly-owned subsidiaries after elimination of all inter-company accounts and transactions.

In June 2010, the Company’s Board of Directors approved a 2-for-1 stock dividend to be effected by issuing one additional share of the Company’s common stock for every share of the Company’s common stock outstanding on the stock dividend record date. The additional shares of the Company’s common stock issued in connection with the stock dividend were distributed on June 1, 2010 to stockholders of record at the close of business on May 19, 2010. All prior period shares outstanding, earnings per share and prices per share have been adjusted to reflect the stock dividend.

Use of estimates: The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.

Foreign currencies: Assets and liabilities of foreign operations where the applicable foreign currency is the functional currency are translated into U.S. dollars at the exchange rate in effect at the end of each accounting period, with any resulting translation adjustment reflected in accumulated other comprehensive income (loss) in the shareholders’ equity section of the balance sheet. Income statement accounts are translated at the average exchange rates prevailing during the period. Gains and losses resulting from balance sheet remeasurement of foreign operations where the U.S. dollar is the functional currency are included in the consolidated statement of earnings as incurred.

Any gains or losses on transactions denominated in a foreign currency are included in the consolidated statements of earnings as incurred.

Cash equivalents: The Company considers all highly liquid investments with maturities of three months or less when purchased to be cash equivalents.

Revenue recognition: Revenue is not recognized until it is realized or realizable and earned. The criteria to meet this guideline are: persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the price to the buyer is fixed or determinable and collectability is reasonably assured. The Company will process a Bill-and-Hold invoice and recognize revenue at the time of the storage request if all of the following criteria are met:

l	The customer has accepted title and risk of loss;
l	The customer has provided a written purchase order for the product;
l	The customer, not the Company, requested the product to be stored and to be invoiced under a Bill-and-Hold arrangement. The customer must also provide the business purpose for the storage request;
l	The customer must provide a storage period and future shipping date;
l	The Company must not have retained any future performance obligations on the product;
l	The Company must segregate the stored product and not make it available to use on other orders; and
l	The product must be completed and ready for shipment.

The Company had $20.3 million, $22.7 million, and $23.8 million in Bill-and-Hold sales outstanding as of December 31, 2010, 2009, and 2008, respectively.

Amounts billed for shipping are classified as sales and costs incurred for shipping are classified as cost of sales in the consolidated statements of earnings.

Accounts & Notes Receivable and Allowance for Doubtful Accounts: Accounts and notes receivable are stated at cost net of write-offs and allowance for doubtful accounts. The Company establishes an allowance for doubtful accounts based on historical experience and any specific customer issues that the Company has identified. Uncollected receivables are generally reserved before being past due over one year or when the Company has determined that the balance will not be collected.

Inventories: The Company reports its inventories by using the last-in, first-out (LIFO) and the first-in, first-out (FIFO) methods less reserves necessary to report inventories at the lower of cost or estimated market. Inventory costs include material, labor and factory overhead. On a routine basis, the Company uses estimates in determining the level of reserves required to state inventory at the lower of cost or market. Management’s estimates are primarily influenced by market activity levels, production requirements, the physical condition of products and technological innovation. Changes in any of these factors may result in adjustments to the carrying value of inventory.

Property, plant and equipment (P. P. & E.): The Company records investments in these assets at cost. Improvements are capitalized, while repair and maintenance costs are charged to operations as incurred. Gains or losses realized on the sale or retirement of these assets are reflected in income. The Company periodically reviews its P. P. & E. for possible impairment whenever events or changes in circumstance might indicate that the carrying amount of an asset may not be recoverable. An impairment loss is recognized if the carrying amount of a long-lived asset is not recoverable and exceeds its fair value. The carrying amount of a long-lived asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. Depreciation for financial reporting purposes is provided on a straight-line method based upon the estimated useful lives of the assets. Accelerated depreciation methods are used for tax purposes. The following is a summary of the Company’s P. P. & E. useful lives:

	Useful Life
	(in years)

Land		-
Land improvements	10.0	-	25.0
Buildings	12.5	-	40.0
Machinery and equipment	3.0	-	15.0
Furniture and fixtures	5.0	-	12.5
Computer equipment and software	3.0	-	7.0

Goodwill and other intangible assets: Goodwill and intangible assets with indefinite lives are not amortized, and are tested for impairment at least annually. During the fourth quarter of 2010, the Company completed its annual impairment evaluation by comparing the fair value of each reporting unit to its carrying amount. No impairment was necessary.

The Company amortizes intangible assets with finite lives over the years expected to be benefited.

Income taxes : The Company computes taxes on income in accordance with the tax rules and regulations of the many taxing jurisdictions where the income is earned. The income tax rates imposed by these taxing authorities vary substantially. Taxable income may differ from pretax income for financial accounting purposes. To the extent that differences are due to revenue or expense items reported in one period for tax purposes and in another period for financial accounting purposes, an appropriate provision for deferred income taxes is made. Any effect of changes in income tax rates or tax laws is included in the provision for income taxes in the period of enactment. When it is more likely than not that all or a portion of a deferred tax asset will not be realized in the future, the Company provides a corresponding valuation allowance against deferred tax assets.

Appropriate U.S. and foreign income taxes have been provided for earnings of foreign subsidiary companies that are expected to be remitted in the near future. The cumulative amount of undistributed earnings of foreign subsidiaries that the Company intends to permanently reinvest and upon which no deferred U.S. income taxes have been provided is $79.8 million at December 31, 2010, the majority of which has been generated in Argentina, Canada and France. Upon distribution of these earnings in the form of dividends or otherwise, the Company may be subject to U.S. income taxes (subject to adjustment for foreign tax credits) and foreign withholding taxes and such amounts could be significant. It is not practical, however, to estimate the amount of taxes that may be payable on the eventual remittance of these earnings after consideration of available foreign tax credits.

The Company is required to determine if an income tax position meets the criteria of more-likely-than-not to be realized based on the merits of the position under tax laws, in order to recognize an income tax benefit. This requires the Company to make many assumptions and judgments regarding merits of income tax positions and the application of income tax law. Additionally, if a tax position meets the recognition criteria of more-likely-than-not the Company is required to make judgments and assumptions to measure the amount of the tax benefits to recognize based on the probability of the amount of tax benefits that would be realized if the tax position was challenged by the taxing authorities. Interpretations and guidance surrounding income tax laws and regulations change over time. As a consequence, changes in assumptions and judgments can materially affect amounts recognized in the consolidated financial statements.

Financial instruments: The Company’s financial instruments include cash, accounts receivable, debt obligations, and accounts payable. The book value of accounts receivable, short-term debt and accounts payable are considered to be representative of their fair value because of the short maturity of these instruments. As of December 31, 2010 and 2009, the Company had no derivative financial instruments.

Stock-based compensation: Employee services received in exchange for stock are expensed. The fair value of the employee services received in exchange for stock is measured based on the grant-date fair value. The fair value is estimated using the Black-Scholes option-pricing model for the stock option. Awards granted are expensed pro-ratably over the service period of the award. As stock based compensation expense is recognized based on awards ultimately expected to vest, compensation expense is reduced for estimated forfeitures based on historical forfeiture rates. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods to reflect actual forfeitures.

Product warranties: The Company sells certain of its products to customers with a product warranty that provides repairs at no cost to the customer or the issuance of credit to the customer. The length of the warranty term depends on the product being sold, but ranges from one year to five years. The Company accrues its estimated liability for warranty claims based upon historical warranty claim costs as a percentage of sales multiplied by prior sales still under warranty at the end of any period. Management reviews these estimates on a regular basis and adjusts the warranty provisions as actual experience differs from historical estimates or other information becomes available.

Recently issued accounting pronouncements:

Management believes the impact of other recently issued guidance, which is not yet effective, will not have a material impact on the Company's consolidated financial statements upon adoption

(2) Acquisitions

On March 1, 2009, the Company completed the acquisition of International Lift Systems, LLC (“ILS”), a Louisiana limited partnership. As a result of this acquisition, the Company entered into a hold back agreement with the former owners of ILS. The total hold back is $4.5 million payable in three equal installments of $1.5 million each plus interest. Interest is calculated annually at 4% of the remaining balance of the hold back portion. The first installment was paid on March 1, 2010; the second and third installments, each plus interest to date, are payable on March 1, 2011 and 2012, respectively. These hold back payments are not contingent upon any subsequent events. At December 31, 2010, the liabilities for these hold back payments were included in accrued liabilities and other liabilities of the Company’s consolidated balance sheets.

On July 1, 2009 the Company completed the acquisition of Rotating Machinery Technology, Inc. (“RMT”), a New York corporation. RMT is a recognized leader in the turbo-machinery industry, specializing in the analysis design and manufacture of precision, custom-engineered tilting-pad bearings and related components for high-speed turbo equipment operating in critical duty applications. RMT also services, repairs and upgrades turbo-expander process units for air and gas separation, both on-site with its skilled field service team and at its repair facility in Wellsville, New York. During the second quarter of 2010, the Company made a one-time payment of $0.3 million, as a result of the final valuation of working capital at the time of the acquisition.

The PHL acquisition has been recorded using the acquisition method of accounting and, accordingly, the acquired operations have been included in the results of operations since the date of acquisition. The preliminary purchase price consideration consists of the following (in thousands of dollars):

Cash paid at closing, net	$	8,015
Royalty consideration		7,076

Total consideration paid	$	15,091

The following table indicates (in thousands of dollars) the preliminary purchase price allocation to net assets acquired, which was based on estimated fair values as of the acquisition date. The excess of the purchase price over the net assets acquired was $7.8 million and has been recorded as goodwill in the accompanying December 31, 2010, consolidated balance sheet. Based on the structure of the transaction, the majority of the goodwill related to the transaction is not expected to be deductible for tax purposes.

Purchase price	$	15,091

Property, plant and equipment		4,135
Intangible assets		2,453
Inventory		675

Goodwill recorded	$	7,828

The Company also entered into a royalty agreement with the former owners of PHL. The agreement is for a ten year period beginning November 1, 2010, and is payable at a rate of 5% for the first five years and 8% for the subsequent five years. Royalties are payable quarterly and are based on product revenues. At December 31, 2010, the estimated present value for these royalty payments were included in the accrued liabilities and other liabilities section of the consolidated balance sheet.

Revenues and earnings to date for the PHL acquisition for all 2010 are not material. Pro forma schedules have not been included as the impact on the prior and current periods presented is not material.

The PHL preliminary purchase price allocation, which is based on relevant facts and circumstances and discussions with an independent third-party consultant, are subject to change upon completion of the final valuation analysis by the Company’s management. The final valuation for PHL, which is required to be completed by October 2011, is not expected to result in material changes to the preliminary allocations.

(3) Discontinued Operations

During the second quarter of 2008, the Trailer segment was classified as a discontinued operation.

The sales amounts included in discontinued operations for 2010 and 2009 are related to the sale of certain tooling, equipment, and spare parts for scrap. As these assets were originally part of the trailer segment they have been included in the operating results of discontinued operations. In addition, the earnings for 2010 and loses for 2009 resulted from the settlement of certain litigation and warranty claims in those respective years.

Operating results of discontinued operations were as follows (in thousands of dollars):

	2010			2009			2008

Sales	$	2		$	36		$	7,135

Earnings (loss) before income tax provision		449			(724	)		450

The Company has a three-year credit facility with a domestic bank (the “Bank Facility”) consisting of an unsecured revolving line of credit that provides up to $80.0 million of aggregate borrowing. The Bank Facility expires on December 31, 2013. Borrowings under the Bank Facility bear interest, at the Company’s option, at either the greater of (i) the prime rate, (ii) the base CD rate plus an applicable margin or (iii) the Federal Funds Effective Rate plus an applicable margin or the London Interbank Offered Rate plus an applicable margin, depending on certain ratios as defined in the Bank Facility. As of December 31, 2010, no debt was outstanding under the Bank Facility and the Company was in compliance with all financial covenants under the terms of the Bank Facility. Deducting outstanding letters of credit of $16.4 million, $63.6 million of borrowing capacity was available at December 31, 2010.

(10) Retirement Benefits

The Company has a qualified noncontributory pension plan covering substantially all U.S. employees. The benefits provided by this plan are measured by length of service, compensation and other factors, and are currently funded by trusts established under the plan. Funding of retirement costs for the plan complies with the minimum funding requirements specified by the Employee Retirement Income Security Act, as amended. In addition, the Company has two unfunded non-qualified deferred compensation pension plans for certain U.S. employees. The Pension Restoration Plan provides supplemental retirement benefits. The benefit is based on the same benefit formula as the qualified pension plan except that it does not limit the amount of a participant's compensation or maximum benefit. The Supplemental Executive Retirement Plan credits an individual with 0.5 years of service for each year of service credited under the qualified plan. The benefits calculated under the non-qualified pension plans are offset by the participant's benefit payable under the qualified plan. The liabilities for the non-qualified deferred compensation pensions plans are included in “Other current accrued liabilities” and “Other liabilities” in the Consolidated Balance Sheet.

The Company is also required by the French government to provide a lump sum benefit payable upon retirement to its French employees. A dedicated insurance policy is in place that can reimburse the Company for these retirement payments.

The Company sponsors two defined benefit postretirement plans that cover both salaried and hourly employees. One plan provides medical benefits, and the other plan provides life insurance benefits. Both plans are contributory, with retiree contributions adjusted periodically. The Company accrues the estimated costs of the plans over the employee’s service periods. The Company's postretirement health care plan is unfunded. For measurement purposes, the submitted claims medical trend was assumed to be 9.25% in 1997. Thereafter, the Company’s obligation is fixed at the amount of the Company’s contribution for 1997.

The Company also has qualified defined contribution retirement plans covering substantially all of its U.S. and Canadian employees. For U.S. employees, the Company makes contributions of 75% of employee contributions up to a maximum employee contribution of 6% of employee earnings. Employees may contribute up to an additional 18% (in 1% increments), which is not subject to matching by the Company. For Canadian employees, the Company makes contributions of 3%-8% of an employee’s salary with no individual employee matching required. All obligations of the Company are funded through December 31, 2010. In addition, the Company provides an unfunded non-qualified deferred compensation defined contribution plan for certain U.S. employees. The Company’s and individual’s contributions are based on the same formula as the qualified contribution plan except that it does not limit the amount of a participant’s compensation or maximum benefit. The contribution calculated under the non-qualified defined contribution plan is offset by the Company’s and participant’s contributions under the qualified plan. The Company’s expense for these plans totaled $3.8 million, $3.3 million and $3.5 million in the years ended December 31, 2010, 2009 and 2008, respectively. The liability for the non-qualified deferred defined contribution plan is included in “Other current accrued liabilities” in the Consolidated Balance Sheet.

For 2010, the Company assumed a long-term asset rate of return of 6.8%. In developing the 6.8% expected long-term rate of return assumption, the Company evaluated input from its third-party pension plan asset manager, including their review of asset class return expectations and long-term inflation assumptions. The Company also considered its historical 10-year and 15-year compounded return (period ended December 31, 2009), which were in-line to higher than the Company’s long-term rate of return assumption, and analyzed expected long-term rate of return projections by asset class.

(12) Earnings per Share

A reconciliation of the number of weighted shares used to compute basic and diluted net earnings per share for 2010, 2009 and 2008, are illustrated below:

	2010		2009		2008
Weighted average common shares outstanding for basic EPS		29,978,034		29,729,874		29,577,734

Effect of dilutive securities: employee stock options		328,328		76,068		242,492

Adjusted weighted average common shares outstanding for diluted EPS		30,306,362		29,805,942		29,820,226

Options to purchase a total of 125,543, 1,042,328 and 335,560 shares of the Company’s common stock were excluded from the calculation of fully diluted earnings per share for 2010, 2009 and 2008, respectively, because their effect on fully diluted earnings per share for the period were antidilutive.

(13) Stock Option Plans

The Company currently has two stock compensation plans. The 1996 Nonemployee Director Stock Option Plan and the 2000 Incentive Stock Compensation Plan provide for the granting of stock options to officers, employees and non-employee directors at an exercise price equal to the fair market value of the stock at the date of grant. The 2000 Incentive Stock Compensation Plan also provides for other forms of stock-based compensation such as restricted stock but none have been granted to date. Options granted to employees vest over two to four years and are exercisable up to ten years from the grant date. Upon retirement, any unvested options become exercisable immediately. Options granted to directors vest at the grant date and are exercisable up to ten years from the grant date.

The following table is a summary of the stock-based compensation expense recognized for the years ended December 31, 2010, 2009 and 2008:

(Thousands of dollars)	2010			2009			2008

Stock-based compensation expense	$	4,627		$	2,943		$	3,584
Tax benefit		(1,712	)		(1,089	)		(1,326	)

Stock-based compensation expense, net of tax	$	2,915		$	1,854		$	2,258

The fair value of each option grant during the years ended December 31, 2010, 2009 and 2008 was estimated on the date of grant using the Black-Scholes option-pricing model with the following assumptions:

The expected dividend yield was based on the dividend yield of the Company’s common stock at the date of the grant. The risk free interest rate was based upon the yield of U.S. Treasuries which terms were equivalent to the expected life of the stock option.

The Company conducts business globally and, as a result, Lufkin Industries, Inc. and its subsidiaries file income tax returns in the U.S. federal and state jurisdictions, and various foreign jurisdictions. For U.S. federal purposes, tax years prior to 2007 are closed to assessment. Statutes for years prior to 2007 remain subject to review in certain U.S. state jurisdictions; however, the outcome of any future audit is not expected to have a material effect on the Company’s results of operations. In early 2010, the Company settled the examination by the State of Texas for the 2005 – 2006 tax years. This settlement did not have a material impact on the Company’s financial statements. The Company also remains subject to income tax examinations in the following material international jurisdictions: Canada (2005-2009), France (2009), and Argentina (2003– 2009). In 2010, the Company also settled two international exams in Argentina for tax years 2004-2008 and in France for tax years 2006-2008. These settlements did not have a material impact on the financial statements.

The Company’s continuing practice is to recognize interest and penalties related to income tax matters in administrative costs. The Company had $131,000 accrued for interest and penalties at December 31, 2009. Interest and penalties of $30,000 were accrued during the twelve months ended December 31, 2010.

(16) Commitments and Contingencies

Legal proceedings: On March 7, 1997, a class action complaint was filed against Lufkin Industries, Inc. (the “Company”) in the U.S. District Court for the Eastern District of Texas by an employee and a former employee of the Company who alleged race discrimination in employment. Certification hearings were conducted in Beaumont, Texas in February 1998 and in Lufkin, Texas in August 1998. In April 1999, the District Court issued a decision that certified a class for this case, which included all black employees employed by the Company from March 6, 1994, to the present. The case was administratively closed from 2001 to 2003 while the parties unsuccessfully attempted mediation. Trial for this case began in December 2003, and after the close of plaintiff’s evidence, the court adjourned and did not complete the trial until October 2004. Although plaintiff’s class certification encompassed a wide variety of employment practices, plaintiffs presented only disparate impact claims relating to discrimination in initial assignments and promotions at trial.

Product warranties: The change in the aggregate product warranty liability for the years ended December 31, 2010 and 2009, is as follows:

Expenses for rentals and leases, including short-term rental contracts, were $7.8 million, $6.0 million and $5.2 million for the years ended December 31, 2010, 2009 and 2008, respectively.

Capital expenditures: As of December 31, 2010, the Company had contractual commitments for capital expenditures of $5.8 million that are expected to be paid in 2011.

(17) Business Segment Information

The Company operates with two business segments: Oil Field and Power Transmission. The two operating segments are supported by a common corporate group. The accounting policies of the segments are the same as those described in the summary of major accounting policies. Corporate expenses and certain assets are allocated to the operating segments primarily based upon third party revenues. Sales by geographic region are determined by the shipping destination of a product or the site of service work. Inter-segment sales and transfers are accounted for as if the sales and transfers were to third parties, that is, at current market prices, as available. The following is a summary of key business segment and product group information:

** Due to the discontinuation of the Trailer segment, certain items previously allocated to that segment have been reclassified to continuing operations.

Total assets	$	621,078	$	541,590

(18) Concentrations of Credit Risk

The Company’s concentration with respect to trade accounts receivable is limited. The large number of customers and diversified customer base across the two segments significantly reduces the Company’s credit risk. The Company also has strict policies regarding the granting of credit to customers and does not offer credit terms to those customers that do not meet certain financial criteria and other guidelines. However, the recent downturn in the global economy has caused a higher level of credit risk. The Company is monitoring the payment practices of customers and is reviewing credit limits more frequently and conservatively than in prior periods. No customer represented over 10% of consolidated company sales as of December 31, 2010. At December 31, 2009 and 2008, one customer represented 11.0% and 15.4%, respectively, of the consolidated Company sales.

Based on their evaluation of the Company’s disclosure controls and procedures as of December 31, 2010, the Chief Executive Officer of the Company, John F. Glick, and the Chief Financial Officer of the Company, Christopher L. Boone, have concluded that the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and Rule 15d-15(e) promulgated under the Securities Exchange Act of 1934, as amended (the Exchange Act)) are effective to ensure that information required to be disclosed in reports that the Company files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and effective to ensure that information required to be disclosed in such reports is accumulated and communicated to the Company’s management, including the Company’s principal executive officer and principal financial officer, to allow timely decisions regarding required disclosure.

There were no changes in the Company’s internal control over financial reporting that occurred during the quarter ended December 31, 2010, that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
