Table of Contents

drilling fluids, which primarily are used to drill water-sensitive shales, reduce torque and drag and are widely used in areas where stuck pipe is likely to occur. In certain drilling areas of the world, oil-base systems exhibit comparably higher penetration rates when compared to water-base systems, significantly reducing time on location and overall drilling costs. Synthetic-base drilling fluids are used in drilling environments where oil-base fluids are environmentally prohibited and provide the performance benefits of oil-base systems. Synthetic-base systems are particularly advantageous in the deepwater environment. M-I SWACO also provides a comprehensive line of reservoir drill-in fluids which combine the high performance properties of a premium drilling fluid with minimal damaging characteristics of a brine completion fluid.
     Completion fluids (clear brines) are solids-free, clear-salt solutions with high specific gravities and are non-damaging to the producing formation. Operators use these specially designed fluid systems in combination with a comprehensive range of specialty chemicals to control bottom-hole pressures, while meeting the specific corrosion inhibition, viscosity and fluid loss requirements necessary during the completion and workover phase of a well. These systems are specially engineered to maximize well production by minimizing formation damage that can be caused by solids-laden systems. M-I SWACO provides a complete line of completion fluids products and services, including low- and high-density brines, specialty chemicals, filtration and chemical treatment services, wellsite engineering and technical and laboratory support services.
     Fluid Competition. The major competitors in the worldwide drilling fluids market, which approximated $6.0 billion in 2006, are Halliburton Energy Services (a division of Halliburton Company (“Halliburton”)) and Baker Hughes Drilling Fluids (a division of Baker Hughes, Inc. (“Baker Hughes”)). While M-I SWACO and these companies supply a majority of the market, the drilling fluids industry is highly competitive, with a significant number of smaller, locally based competitors. The major competitors in the worldwide completion fluids market, which approximated $1.2 billion in 2006, are Baroid Completion Fluids (a division of Halliburton), Tetra Technologies, Inc., and Baker Hughes.
     Generally competition for sales of drilling and completions fluids is based on a number of factors, including wellsite engineering services, product quality and availability, technical support, service response and price.
     M-I SWACO Drilling Waste Management. M-I SWACO provides services, equipment and engineering for solids control, pressure control and waste management to the worldwide drilling market.
     Solids-control equipment is used to remove drill cuttings from the fluid system, allowing the drilling fluid to be cleaned and recirculated. Solids are normally separated from the drilling fluid using one or a combination of the following: balanced elliptical and linear-motion shale shakers, desanders, desilters, hydroclones, mud cleaners and centrifuges. M-I SWACO designs, manufactures, sells and rents a comprehensive, proprietary line of this equipment for oil and gas drilling processes throughout the world. The Company is also a leading manufacturer and supplier of screens used in solids-control equipment for both oilfield and certain industrial markets. M-I SWACO complements its product offering by providing engineering and technical support to operators and drilling contractors from the planning stages of their projects through waste removal and site remediation.
     Operators employ M-I SWACO-manufactured pressure-control equipment to drill in sour-gas and high-pressure zones. Well killing and high-pressure control drilling chokes, together with related operating consoles, are used in the drilling process during well kicks and well clean-up and testing operations. Degassers and mud gas separators are designed to remove and vent entrained gases, including toxic gases such as hydrogen sulfide and corrosive oxygen, from the drilling mud. This equipment reduces the risk of dangerous and costly blowouts caused by recirculating mud that contains natural gas. Key products in M-I SWACO’s pressure control product line include the Mud D-Gasser® and Super Choke™, both of which hold strong market positions as do the Super Mud Gas SeparatorÔ and the Super AutochokeÔ.
     With drilling operations expanding into more environmentally sensitive areas, there has been increased focus on the effective collection, treatment and disposal of waste produced during the drilling of a well. M-I SWACO provides operators with solutions designed to minimize and treat drilling waste. The Company provides a suite of waste handling, minimization and management products and services, including the CleanCut® pneumatic conveyance system for collection and transportation of drill cuttings related to offshore drilling programs. M-I SWACO also provides rig vacuum systems for cuttings recovery, high-gravity force drying equipment for liquid/solid separation and cuttings slurification and re-injection processes for reducing haul-off waste. In addition, through the Thermal Phase Separation™ process, M-I SWACO provides operators a proven technology for maximizing the recovery of drilling fluids, while minimizing wastes. M-I SWACO’s waste treatment services encompass a wide range of activities, including site assessment, drill cuttings injection, water treatment, pit closure and remediation, bioremediation, dewatering and thermal processing. The Company has established EnviroCenters® in Norway, Germany and the United States designed specifically for recovering, treating and recycling solid and liquid drilling wastes.

     M-I SWACO Drilling Waste Management Competition. M-I SWACO competes with Brandt/Rigtech (a subsidiary of National Oilwell Varco, Inc. (“National-Oilwell Varco”)) and Derrick/Oil Tools. Additionally, there are a number of regional suppliers that provide a limited range of equipment and services tailored for local markets. Competition is based on product availability, equipment performance, technical support and price.
     Oilfield Production Chemicals. M-I SWACO provides a line of oilfield specialty chemicals and related technical services through its Oilfield Production Chemical division. Oilfield production chemicals are used to enhance the flow of hydrocarbons from the wellbore by eliminating paraffin, scale and other byproducts encountered during the production process. Oilfield production chemicals are also used to protect piping and other equipment associated with the production, transportation and processing of oil and gas.
     Production Chemical Competition. The major competitors in the worldwide oilfield production chemical market include Baker Petrolite (a division of Baker Hughes), Nalco Energy Services (a division of Nalco Company) and Champion Technologies, Inc. Generally, competition is based on product quality, product performance, technical support and price.
Smith Technologies
     Products and Services. Smith Technologies is a worldwide leader in the design, manufacture and marketing of drill bits primarily used in drilling oil and natural gas wells. In addition, Smith Technologies is a leading provider of downhole turbine drilling products (referred to as “turbodrills”) and services that enhance the operating performance of petroleum drill bits in certain applications. Smith Technologies’ product offerings are designed principally for the premium market segments where faster drilling rates and greater footage drilled provide significant economic benefits in reducing the total cost of a well.
     Smith Technologies designs, manufactures and markets three-cone drill bits for the petroleum industry, ranging in size from 31/2 to 32 inches in diameter. Three-cone bits work by crushing and shearing the rock formation as the bit is turned. These three-cone bits comprise two major components — the body and the cones, which contain different types of pointed structures referred to as “cutting structures” or “teeth.” The cutting structures are either an integral part of the steel cone with a hardmetal-applied surface (referred to as “milled tooth”) or made of an inserted material (referred to as “insert”), which is usually tungsten carbide. The Company also produces three-cone drill bits in which the tungsten carbide insert is coated with polycrystalline diamond. In certain formations, bits produced with diamond-enhanced inserts last longer and increase penetration rates, which substantially decreases overall drilling costs. Smith Technologies is a leading provider of drill bits utilizing diamond-enhanced insert technology.
     In addition, Smith Technologies designs, manufactures and markets diamond drill bits. Diamond bits consist of a single body made of either a matrix powder alloy or steel. The cutting structures of diamond bits consist of either polycrystalline diamond cutters, which are brazed on the bit, or natural or synthetic diamonds, which are impregnated in the bit. These bits, which range in size from 23/4 to 26 inches in diameter, work by shearing the rock formation with a milling action as the bit is turned. Smith Technologies has experienced increased demand for rental of diamond bits as improved designs and manufacturing processes have allowed a diamond bit to be used to drill multiple wells in certain markets.
     Smith Technologies also designs, assembles and markets a comprehensive line of turbodrills and provides related technical support. Turbodrills, which operate directly above the drill bit, use the hydraulic energy provided by drilling fluid pumps on the rig floor to deliver torque to and rotate the drill bit. These proprietary tools are designed to provide faster rates of penetration, operate in much higher temperature formations, deliver longer downhole life and produce better wellbore quality than conventional positive displacement drilling motors. The turbine drilling motor provides operators with cost effective solutions in demanding environments such as horizontal applications, hard formations and high-temperature zones.
     The Company manufactures polycrystalline diamond and cubic boron nitride materials that are used in the Company’s three-cone and diamond drill bits and other specialized cutting tools. The Company believes that it is one of the world’s largest manufacturers of polycrystalline diamond for use in oilfield applications. Smith Technologies also develops and uses patented processes for applying diamonds to a curved surface which optimize the performance of inserts used in drill bits. As a result, the Company believes that Smith Technologies enjoys a competitive advantage in both material cost and technical ability over other drill bit companies. In addition, the Company’s in-house diamond research, engineering and manufacturing capabilities enhance the Company’s ability to develop the application of diamond technology across other Smith product lines and into non-energy markets.

     Competition. Hughes Christensen (a division of Baker Hughes), Security DBS (a division of Halliburton) and ReedHycalog (a division of Grant Prideco, Inc.) are the three major competitors of Smith Technologies in the drill bit business. While Smith Technologies and these companies supply the majority of the worldwide drill bit market, which approximated $2.6 billion in 2006, they compete with more than 20 companies. Generally, competition for sales of drill bits is based on a number of factors, including performance, quality, reliability, service, price, technological advances and breadth of products. The Company believes its quality, reliability and technological advances provide its products with a competitive advantage.
Smith Services
     Products and Services. Smith Services is a leading global provider of technologically advanced drilling, tubular, fishing, remedial, multilateral and completion products, services and solutions to the oil and gas drilling industry.
     Smith Services’ Drilling Products and Services business provides a broad range of downhole impact tools for drilling applications as well as numerous other specialized downhole drilling products and services. Smith Services sells and rents impact drilling tools such as the Hydra-Jar®Tool and the Accelerator®Tool, which are used to free stuck drill strings during the drilling process. Additionally, Drilling on Gauge Subs and Borrox AP Reamers are some of the Company’s tools used by operators for maintaining hole gauge and quality of the wellbore. Smith Services also offers tubular drill string components, such as drill collars, subs, stabilizers, kellys and Hevi-WateÔDrillPipe, and provides related inspection services, including drillstring repair and rebuild services. These components and their placement in the drillstring are supported by engineering and field technical services in order to optimize bottom hole management techniques. Through state-of-the-art software, Smith Services aids the customer in maximizing the life of drillstring components. Rotating control devices for flow control in underbalanced / managed pressure drilling applications and automatic connection torque monitoring and control systems are designed and manufactured by Smith Services. Smith Services also manufactures and markets hole openers and underreamers which are designed to create larger hole diameters in certain sections of the wellbore. The Company’s patented Rhino® Reamer, Reamaster®and simultaneous drilling and hole enlargement system are three examples of products that aid the customer in realizing lower drilling costs through technology. Through the use of the simultaneous drilling and hole enlargement system above the drill bit, the operator may drill the main well bore with the bit and enlarge the diameter of the hole above the drill bit in the same run.
     Smith Services’ Fishing and Remedial Services business provides a comprehensive package of fishing, remedial and thru-tubing services. Fishing operations clear and remove obstructions from a wellbore that may arise during drilling, completion or workover activities or during a well’s production phase. This operation requires a wide variety of specialty tools, including fishing jars, milling tools and casing cutters, all of which are manufactured by Smith Services. These tools are operated by Company service personnel or sold or rented to third-party fishing companies.
     Smith Services provides Wellbore Departure™ Systems through the manufacture of proprietary casing exit tools which are installed by trained technicians. These systems, which include the patented Trackmaster® Plus Whipstock System, allow the operator to divert around obstructions in the main wellbore or reach multiple production zones from the main wellbore (known as multilateral completions). In addition, Smith Services’ Geotrack™ Whipstock System mills the casing exit and continues to drill several hundred feet of formation in a single trip, saving the customer time and reducing their overall drilling costs. The Company also provides mechanical, hydraulic and explosive pipe-cutting services to remove casing during well or platform abandonment.
     Smith Services’ Completion Systems business specializes in providing fit-for-purpose liner hanger systems, liner cementing equipment, isolation packers, retrievable and permanent packers, and drillable bridge and frac plugs. Liner hangers allow strings of casing to be suspended within the wellbore without having to extend the string all the way to the surface and are also used to isolate production zones and formations. Most directional and multilateral wells include one or more hangers due to complex casing programs and need for zonal isolation. Using Smith Services’ Pocket SlipÔ liner hanger system, long or heavy liners can be suspended with minimal casing distortion and maximum flow-by area. Packers are mechanically or hydraulically actuated devices which lock into place at specified depths in the well and provide a seal between zones through expanding-element systems. The devices therefore create isolated zones within the wellbore to permit either specific formation production or allow for certain operations, such as cementing or acidizing, to take place without damaging the reservoir. The Smith Services IsofracÔ packer selectively isolates multiple zones in a single trip to reduce fracturing job time, while the Long ReachÔ packer facilitates successful liner deployment in vertical and long reach horizontal wellbores without excessive work string manipulation. In addition, Smith Services’ top drive cementing manifold eliminates cement contamination of top drive components by creating a flow path for cement that bypasses the drilling rig’s top drive assembly.

(“Weatherford”), Baker Oil Tools (a division of Baker Hughes) and numerous small local companies. The main competitors in the liner hanger and packer markets are Baker Oil Tools, Weatherford and TIW Corporation. The main competitors in the drilling and fishing jar market and the fishing product and service market are Weatherford and National-Oilwell Varco. Competition in the drilling and completions sales, rental and services market is primarily based on performance, quality, reliability, service, price and response time and, in some cases, breadth of products.
Distribution Segment
Wilson
     Products and Services. Wilson is a supply-chain management company which provides products and services to the energy, refining, petrochemical, power generation and mining industries. Wilson operates an extensive network of supply branches, service centers and sales offices through which it markets pipe, valves and fittings as well as mill, safety and other maintenance products, predominately in the United States and Canada. In addition, Wilson provides warehouse management, vendor integration and various surplus and inventory management services. The majority of Wilson’s operations are focused on North American distribution of maintenance, repair and operating supplies and equipment with the remainder associated with line pipe and automated valve products (including valve, actuator and control packages).
     Approximately 72 percent of Wilson’s 2006 revenues were generated in the energy sector, which includes exploration and production companies and companies with operations in the petroleum industry’s pipeline sector. The remainder related to sales in the downstream and industrial market, including refineries, petrochemical and power generation plants and other energy-focused operations. Approximately 25 percent of Wilson’s 2006 revenues were reported in Canada, attributable to the CE Franklin Ltd. operations, a publicly-traded distribution business in which the Company owns the majority of the outstanding common stock.
     Competition. Wilson’s competitors in its energy sector operations include National-Oilwell Varco, Redman Pipe and Supply Company and a significant number of smaller, locally based operations. Wilson’s competitors in the downstream and industrial market include Hagemeyer NV, Ferguson Enterprises, Inc., McJunkin Corporation and W.W. Grainger, Inc. The distribution market that Wilson participates in is highly competitive. Generally, competition involves numerous factors, including price, experience, customer service and equipment availability.
Non-U.S. Operations
     Sales to oil and gas exploration and production markets outside the United States are a key strategic focus of Smith’s management. The Company markets its products and services through subsidiaries, joint ventures and sales agents located in virtually all petroleum-producing areas of the world, including Canada, Latin America, Europe/Africa, and Middle East/Asia. Approximately 54 percent, 55 percent and 55 percent of the Company’s revenues in 2006, 2005 and 2004, respectively, were derived from equipment or services sold or provided outside the United States. The Company’s Distribution operations constitute a significant portion of the consolidated revenue base and are concentrated in North America which serves to distort the geographic revenue mix of the Company’s Oilfield segment operations. Excluding the impact of the Distribution operations, approximately 63 percent, 65 percent and 65 percent of the Company’s revenues were generated in non-U.S. markets in 2006, 2005 and 2004, respectively.
     Historically, drilling activity outside the United States has been less volatile than U.S.-based activity as the high cost exploration and production programs outside the United States are generally undertaken by major oil companies, consortiums and national oil companies. These entities operate under longer-term strategic priorities than do the independent drilling operators that are more common in the U.S. market.
Sales and Distribution
     Sales and service efforts are directed to end users in the exploration and production industry, including major and independent oil companies, national oil companies and independent drilling contractors. The Company’s products and services are primarily marketed through the direct sales force of each business unit. In certain non-U.S. markets where direct sales efforts are not practicable, the Company utilizes independent sales agents, distributors or joint ventures.

Table of Contents

     Smith maintains field service centers, which function as repair and maintenance facilities for rental tools, operations for remedial and completion services and a base for the Company’s global sales force, in all major oil and gas producing regions of the world. The location of these service centers near the Company’s customers is an important factor in maintaining favorable customer relations.
Manufacturing
     The Company’s manufacturing operations, along with quality control support, are designed to ensure that all products and services marketed by the Company will meet standards of performance and reliability consistent with the Company’s reputation in the industry.
     Management believes that it generally has sufficient internal manufacturing capacity to meet anticipated demand for its products and services. During periods of peak demand, certain business units utilize outside resources to provide additional manufacturing capacity.
Raw Materials
     Through its company-owned mines in and outside the United States, M-I SWACO has the capability to produce a large portion of its requirements for barite and bentonite, which are typically added to engineered fluid systems. Barite reserves are mined in the United States, the United Kingdom and Morocco. Bentonite is produced from ore deposits in the U.S. Mining exploration activities continue worldwide to locate and evaluate ore bodies to ensure deposits are readily available for production when market conditions dictate. In addition to its own production, M-I SWACO purchases the majority of its worldwide barite requirement from suppliers outside the United States, mainly the People’s Republic of China, India and Morocco.
     The Company purchases a variety of raw materials for its Smith Technologies and Smith Services units, including alloy and stainless steel bars, tungsten carbide inserts and forgings. Generally, the Company is not dependent on any single source of supply for any of its raw materials or purchased components, and believes that numerous alternative supply sources are available for all such materials. The Company does not expect any interruption in supply, but there can be no assurance that there will be no price or supply issues over the long-term. The Company produces polycrystalline diamond materials in Provo, Utah and Scurelle, Italy for utilization in various Company products as well as direct customer sales.
Product Development, Engineering and Patents
     The Company’s business units maintain product development and engineering departments whose activities are focused on improving existing products and services and developing new technologies to meet customer demands for improved drilling performance and environmental-based solutions for drilling and completion operations. The Company’s primary research facilities are located in Houston, Texas; Stavanger, Norway; Aberdeen, Scotland; and Florence, Kentucky.
     The Company also maintains a drill bit database which records the performance of drill bits over the last 20 years, including those manufactured by competitors. This database gives the Company the ability to monitor, among other things, drill bit failures and performance improvements related to product development. The Company believes this proprietary database gives it a competitive advantage in the drill bit business.
     The Company has historically invested significant resources in research and engineering in order to provide customers with broader product lines and technologically-advanced products and services. The Company’s expenditures for research and engineering activities are attributable to the Company’s Oilfield Products and Services segment and totaled $88.3 million in 2006, $73.6 million in 2005 and $67.2 million in 2004. In 2006, research and engineering expenditures approximated 1.6 percent of the Company’s Oilfield Products and Services segment revenues.
     Although the Company has over 3,900 issued and pending patents and regards its patents and patent applications as important in the operation of its business, it does not believe that any significant portion of its business is materially dependent upon any single patent.
Employees
     At December 31, 2006, the Company had 17,377 full-time employees throughout the world. Most of the Company’s employees in the United States are not covered by collective bargaining agreements except in certain U.S. mining operations of M-I SWACO and several distribution locations of Wilson. The Company considers its labor relations to be satisfactory.

Item 1A. Risk Factors
     This document contains forward-looking statements within the meaning of the Section 21E of the Securities Exchange Act of 1934, as amended, concerning, among other things, our outlook, financial projections and business strategies, all of which are subject to risks, uncertainties and assumptions. These forward-looking statements are identified by their use of terms such as “anticipate,” “believe,” “could,” “estimate,” “expect,” “project” and similar terms. These statements are based on certain assumptions and analyses that we believe are appropriate under the circumstances. Such statements are subject to, among other things, general economic and business conditions, the level of oil and natural gas exploration and development activities, global economic growth and activity, political stability of oil-producing countries, finding and development costs of operations, decline and depletion rates for oil and natural gas wells, seasonal weather conditions, industry conditions, and changes in laws or regulations, many of which are beyond the control of the Company. Should one or more of these risks or uncertainties materialize, or should the assumptions prove incorrect, actual results may differ materially from those expected, estimated or projected. Our management believes these forward-looking statements are reasonable. However, you should not place undue reliance on these forward-looking statements, which are based only on our current expectations. Forward-looking statements speak only as of the date they are made, and we undertake no obligation to publicly update or revise any of them in light of new information, future events or otherwise.
     With this in mind, you should consider the risks discussed elsewhere in this report and other documents we file with the Securities and Exchange Commission from time to time and the following important factors that could cause our actual results to differ materially from those expressed in any forward-looking statement made by us or on our behalf.
We are dependent on the level of oil and natural gas exploration and development activities.
     Demand for our products and services is dependent upon the level of oil and natural gas exploration and development activities. The level of worldwide oil and natural gas development activities is primarily influenced by the price of oil and natural gas, as well as price expectations. In addition to oil and natural gas prices, the following factors impact exploration and development activity and may lead to significant changes in worldwide activity levels:
    Overall level of global economic growth and activity;
 
    Actual and perceived changes in the supply and demand for oil and natural gas;
 
    Political stability and policies of oil-producing countries;
 
    Finding and development costs of operators;
 
    Decline and depletion rates for oil and natural gas wells; and
 
    Seasonal weather conditions that temporarily curtail drilling operations.
     Changes in any of these factors could adversely impact our financial condition or results of operations.
There are certain risks associated with conducting business in markets outside of North America.
     We are a multinational oilfield service company and generate the majority of our Oilfield segment revenues in markets outside of North America. Changes in conditions within certain countries that have historically experienced a high degree of political and/or economic instability could adversely impact our financial condition or results of operations. Additional risks inherent in our non-North American business activities include:
    Changes in political and economic conditions in the countries in which we operate, including civil uprisings, riots and terrorist acts;
 
    Unexpected changes in regulatory requirements;
 
    Fluctuations in currency exchange rates and the value of the U.S. dollar;
 
    Restrictions on repatriation of earnings or expropriation of property without fair compensation;
 
    Governmental actions that result in the deprivation of contract rights; and
 
    Governmental sanctions.

We operate in a highly technical and competitive environment.
     We operate in a highly-competitive business environment. Accordingly, demand for our products and services is largely dependent on our ability to provide leading-edge, technology-based solutions that reduce the operator’s overall cost of developing energy assets. If competitive or other market conditions impact our ability to continue providing superior-performing product offerings, our financial condition or results of operations could be adversely impacted.
Our businesses are subject to a variety of governmental regulations.
     We are exposed to a variety of federal, state, local and international laws and regulations relating to matters such as environmental, health and safety, export control, currency exchange, labor and employment and taxation. These laws and regulations are complex, change frequently and have tended to become more stringent over time. In the event the scope of these laws and regulations expand in the future, the incremental cost of compliance could adversely impact our financial condition or results of operations.
Our industry is experiencing more litigation involving claims of infringement of intellectual property rights.
     Over the past few years, our industry has experienced increased litigation related to the infringement of intellectual property rights. Although no material matters are pending or threatened at this time, we, as well as certain of our competitors, have been named as defendants in various intellectual property matters in the past. These types of claims are typically costly to defend, involve monetary judgments that, in certain circumstances, are subject to being enhanced and are often brought in venues which have proved to be favorable to plaintiffs. If we are served with an intellectual property claim which we are unsuccessful in defending, it could adversely impact our results of operations and cash flows.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations
General
     The following “Management’s Discussion and Analysis of Financial Condition and Results of Operations” is provided to assist readers in understanding the Company’s financial performance during the periods presented and significant trends which may impact the future performance of the Company. This discussion should be read in conjunction with the Consolidated Financial Statements of the Company and the related notes thereto included elsewhere in this Form 10-K. This discussion includes forward-looking statements that are subject to risks and uncertainties. Actual results may differ materially from the statements we make in this section due to a number of factors that are discussed beginning on page 9.
Company Products and Operations
     The Company is a leading global provider of premium products and services to the oil and gas exploration and production industry. The Company provides a comprehensive line of technologically-advanced products and engineering services, including drilling and completion fluid systems, solids-control and separation equipment, waste-management services, oilfield production chemicals, three-cone and diamond drill bits, turbine products, tubulars, fishing services, drilling tools, underreamers, casing exit and multilateral systems, packers and liner hangers. The Company also offers supply chain management solutions through an extensive North American branch network providing pipe, valves and fittings as well as mill, safety and other maintenance products.
     The Company’s operations are largely driven by the level of exploration and production (“E&P”) spending in major energy-producing regions around the world and the depth and complexity of these projects. Although E&P spending is significantly influenced by the market price of oil and natural gas, it may also be affected by supply and demand fundamentals, finding and development costs, decline and depletion rates, political actions and uncertainties, environmental concerns, the financial condition of independent E&P companies and the overall level of global economic growth and activity. In addition, approximately eight percent of the Company’s consolidated revenues relate to the downstream energy sector, including petrochemical plants and refineries, whose spending is largely impacted by the general condition of the U.S. economy.
     Capital investment by energy companies is largely divided into two markets, which vary greatly in terms of primary business drivers and associated volatility levels. North American drilling activity is primarily influenced by natural gas fundamentals, with approximately 82 percent of the current rig count focused on natural gas finding and development activities. Conversely, drilling in areas outside of North America is more dependent on crude oil fundamentals, which influence over three-quarters of international drilling activity. Historically, business in markets outside of North America has proved to be less volatile as the high cost E&P programs in these regions are generally undertaken by major oil companies, consortiums and national oil companies as part of a longer-term strategic development plan. Although close to 60 percent of the Company’s consolidated revenues were generated in North America during 2006, Smith’s profitability was largely dependent upon business levels in markets outside of North America. The Distribution segment, which accounts for approximately 26 percent of consolidated revenues and primarily supports a North American customer base, serves to distort the geographic revenue mix of the Company. Excluding the impact of the Distribution segment, 55 percent of the Company’s 2006 revenues were generated in markets outside of North America.
Business Outlook
     The Company’s business is highly dependent on the general economic environment in the United States and other major world economies, which impact energy consumption and the resulting demand for our products and services. In 2006, the average worldwide rig count grew 13 percent over the prior year period influenced, in part, by higher commodity prices which resulted in increased investment in oil-focused drilling projects in markets outside of North America.
     The Company anticipates modest growth in exploration and production spending in 2007 which is expected to be concentrated in the Eastern Hemisphere regions and, to a lesser extent, in the U.S. offshore market. Although the long-term outlook for North American land-based drilling activity is favorable based upon expected growth in worldwide energy consumption, an adverse change in near-term market fundamentals could cause activity reductions for marginal land-based projects.
     There are a number of factors which influence forecasted exploration and production spending. Ultimately, any significant deterioration in the global economic environment or prolonged weakness in commodity prices could affect worldwide drilling activity and demand for our products and services.

Oilfield Segment
Revenues
     M-I SWACO primarily provides drilling and completion fluid systems, engineering and technical services to the oil and gas industry. Additionally, these operations provide oilfield production chemicals and manufacture and market equipment and services used for solids-control, particle separation, pressure control, rig instrumentation and waste-management. M-I SWACO is significantly influenced by exploration and production spending in markets outside of North America, which contributes approximately two-thirds of the unit’s revenues, and by its exposure to the U.S. offshore market, which constitutes nine percent of the revenue base. U.S. offshore drilling accounts for approximately three percent of the worldwide rig count and generally is more revenue-intensive than land-based projects due to the complex nature of the related drilling environment. For the year ended December 31, 2006, M-I SWACO reported revenues of $3.6 billion, an increase of 33 percent over the prior year period. Excluding the impact of acquired operations, revenues grew 31 percent over the prior year. Approximately two-thirds of the base revenue increase was generated in markets outside of North America, primarily reflecting new contract awards and increased customer activity in the Europe/Africa and Middle East offshore markets. North American base revenues grew 33 percent above the prior year level, largely attributable to increased investment by exploration and production companies in land-based drilling projects and the impact of price increases implemented in late 2005. M-I SWACO’s revenues totaled $2.7 billion for the year ended December 31, 2005, an increase of 20 percent over the prior year period. Over 60 percent of the business growth was generated in the Eastern Hemisphere influenced by an 11 percent increase in corresponding activity levels and the impact of new contract awards. Increased exploration and production spending in the North American market, driven by the significant increase in the number of land-based drilling programs and, to a lesser extent, the impact of price increases initiated throughout 2005 also contributed to the year-over-year revenue improvement.
     Smith Technologies designs and manufactures three-cone drill bits, diamond drill bits and turbines for use in the oil and gas industry. Due to the nature of its product offerings, revenues for these operations typically correlate more closely to the rig count than any of the Company’s other businesses. For the year ended December 31, 2006, Smith Technologies reported revenues of $790.1 million, an increase of 31 percent over the prior year period. The majority of the revenue increase was reported by the Western Hemisphere operations, influenced by higher U.S. land-based drilling activity, improved pricing and, to a lesser extent, strong demand for turbine products in the Latin America market. Revenues generated in the Eastern Hemisphere region increased 30 percent, contributing one-third of the revenue improvement over the prior year period. The year-over-year increase reflects growth in the Middle East, Former Soviet Union (“FSU”) and the North Sea area, attributable to new contract awards and improved market penetration. Smith Technologies reported revenues of $601.8 million for the year ended December 31, 2005, an 18 percent increase over the prior year level. The year-over-year revenue growth resulted from increased unit sales and rentals of diamond drill bits, as technological advancements in fixed cutter drill bit manufacturing and design has influenced a shift from roller-cone toward diamond drill bit product offerings. To a lesser extent, the impact of higher unit pricing and continued demand for turbine products contributed to the year-over-year revenue improvement.
     Smith Services manufactures and markets products and services used in the oil and gas industry for drilling, work-over, well completion and well re-entry. Revenues for Smith Services are relatively balanced between North America and the international markets and are heavily influenced by the complexity of drilling projects, which drive demand for a wider range of its product offerings. For the year ended December 31, 2006, Smith Services reported revenues of $1.0 billion, 47 percent above the prior year period. The year-over-year revenue growth was significantly influenced by increased demand for tubular products in the U.S. market. Excluding the impact of tubular product sales, which are not highly correlated to drilling activity, business volumes increased 29 percent above the prior year period. Two-thirds of the core business growth was reported in North America, reflecting increased customer demand for premium remedial product and service lines. The revenue growth in markets outside of North America was, again, driven by increased demand for remedial product offerings, primarily in the Middle East, North Sea and FSU regions. Smith Services reported revenues of $694.7 million for the year ended December 31, 2005, a 41 percent increase over the amount reported in 2004. Excluding the effect of acquired operations, revenues increased 34 percent influenced by higher worldwide exploration and production spending levels. The majority of the base revenue growth was generated in North America, as increased activity levels impacted tubular product sales, which were twice the level reported in the prior year. Approximately one-third of the year-over-year base revenue growth was reported in markets outside of North America, driven by strong demand for remedial product and service lines in the Middle East and North Sea markets.

Operating Income
     Operating income for the Oilfield segment was $1.0 billion, or 18.8 percent of revenues, for the 2006 fiscal year period. The segment operating margins were 3.1 percentage points above the prior year level with incremental operating income approximating 28 percent of revenues. The operating margin growth was predominantly driven by increased business volumes, but was also favorably impacted by an improved business mix and pricing initiatives. To a lesser extent, the margin improvement was influenced by improved general and administrative cost coverage. On an absolute dollar basis, fiscal 2006 operating income increased $386.9 million over the prior year, largely attributable to the impact of a 35 percent increase in business volumes on gross profit, mitigated by higher variable-based operating expenses, including investment in personnel and infrastructure to support the expanding business operations. For the year ended December 31, 2005, Oilfield operating income was $625.4 million, or 15.7 percent of revenues. The year-over-year comparison to 2004 was impacted by litigation-related charges, including $5.6 million and $31.4 million in 2005 and 2004, respectively. Excluding the impact of these charges, segment operating margins increased 1.8 percentage points above the 2004 level. The year-over-year operating margin expansion primarily reflects reduced operating expenses as a percentage of revenues associated with improved fixed cost coverage in the sales and administrative functions. Gross margins improved slightly reflecting the impact of increased fixed cost absorption in the segment’s manufacturing operations and higher unit pricing, partially offset by a combination of an unfavorable shift in business mix and rising commodity costs. Fiscal 2005 operating income increased $175.9 million over the 2004 period, net of the litigation-related charges. The growth in operating income was attributable to the impact of higher business volumes on gross profit, partially offset by higher variable-based operating expenses associated with the expanding business base.
Distribution Segment
Revenues
     Wilson markets pipe, valves, fittings and mill, safety and other maintenance products to energy and industrial markets, primarily through an extensive network of supply branches in the United States and Canada. The segment has the most significant North American revenue exposure of any of the Company’s operations with approximately 96 percent of Wilson’s 2006 revenues generated in those markets. Moreover, approximately 28 percent of Wilson’s revenues relate to sales to the downstream energy sector, including petrochemical plants and refineries, whose spending is largely influenced by the general state of the U.S. economic environment. Additionally, certain customers in this sector utilize petroleum products as a base material and, accordingly, are adversely impacted by increases in crude oil and natural gas prices. For the year ended December 31, 2006, Wilson reported revenues of $1.9 billion, 22 percent above the prior year. Two-thirds of the revenue growth was generated by the upstream energy operations, reflecting higher spending by exploration and production companies associated with increased North American drilling and completion activity and the impact of new contract awards. Industrial and downstream sales volumes grew 13 percent, influenced by increased customer spending related to line pipe projects. Wilson reported revenues totaling $1.6 billion for the year ended December 31, 2005, an increase of 35 percent from the 2004 fiscal year. Approximately three-quarters of the revenue growth was generated in the upstream energy operations reflecting higher spending by exploration and production companies associated with increased North American drilling and completion activity, the impact of new contract awards and strong demand for tubular products. Industrial and downstream sales volumes grew 17 percent above 2004 levels, influenced by increased spending levels for line pipe and maintenance and repair projects primarily in the engineering and construction and petrochemical customer base.
Operating Income
     Operating income for the Distribution segment in fiscal 2006 was $101.8 million, or 5.2 percent of revenues. The operating margin improvement of 1.2 percentage points reflects lower operating expenses as a percentage of revenues and, to a lesser extent, gross margin expansion. Incremental operating income was 11 percent of revenues, with the majority of the growth attributable to the energy sector operations, influenced by increased coverage of fixed sales and administrative costs. On an absolute dollar basis, segment operating income was $37.1 million above the amount reported in 2005, impacted by a 22 percent increase in revenue volumes on the segment’s reported gross profit, partially offset by higher variable-based operating expenses. For the year ended December 31, 2005, operating income for the Distribution segment was $64.7 million, or four percent of revenues. Distribution operating results increased $38.2 million over the amount reported in 2004, equating to incremental operating income of nine percent of revenues. Incremental operating income was driven by the energy sector operations reflecting increased coverage of fixed sales and administrative costs. The lower expense ratio more than offset deterioration in gross profit margins associated with increased tubular product costs and a higher mix of project and export orders, which typically generate lower comparable margins.

2006 versus 2005
      Consolidated revenues increased to $7.3 billion for the year ended December 31, 2006, 31 percent above the prior year period. The majority of the year-over-year revenue growth was reported in the Oilfield segment attributable to a combination of higher worldwide drilling activity, a favorable product and business mix and, to a lesser extent, improved pricing. On a geographic basis, two-thirds of the revenue improvement was generated in the Western Hemisphere market, which accounted for the majority of the year-over-year increase in drilling activity levels. The year-over-year revenue growth was also driven by the strength in the Company’s international operations which reported a 33 percent increase in revenues.
     Gross profit totaled $2.3 billion, or 32 percent of revenues, two percentage points above the gross profit margins generated in the comparable prior year period. Although the margin expansion was largely driven by the impact of increased sales volumes on fixed manufacturing and service infrastructure costs, an improved business mix and product pricing also had a favorable effect. On an absolute dollar basis, gross profit was $659.1 million above the prior year period primarily reflecting the increased sales volumes in the Oilfield operations.
     Operating expenses, consisting of selling, general and administrative expenses increased $249.6 million from the amount reported in the prior year; however, as a percentage of revenues decreased 95 basis points. Improved fixed cost average in the sales and administrative functions accounted for the operating expense percentage decline. The majority of the absolute dollar increase was attributable to variable costs directly associated with the improved business volumes, including increased investment in personnel and infrastructure. To a lesser extent, increased employee profit-sharing amounts directly attributable to the reported profitability levels, incremental operating expenses of acquired operations and stock-based compensation expense also contributed to the year-over-year operating expense growth.
     Net interest expense, which represents interest expense less interest income, totaled $60.0 million in 2006. Net interest expense increased $17.2 million from the prior year reflecting higher average debt levels in 2006 due to borrowings related to the financing of several acquisitions and, to a lesser extent, an increase in variable interest rates.

     The effective tax rate approximated 32 percent, partially impacted by the settlement of a U.S. tax audit that resulted in the release of certain deferred tax reserves during the second quarter of 2006. Excluding the tax settlement, the effective rate was comparable to the level reported in the prior year, but below the U.S. statutory rate due to the impact of M-I SWACO’s U.S. partnership earnings for which the minority partner is directly responsible for its related income taxes. The Company properly consolidates the pretax income related to the minority partner’s share of U.S. partnership earnings but excludes the related tax provision.
     Minority interests reflect the portion of the results of majority-owned operations which are applicable to the minority interest partners. Minority interests totaled $191.4 million in 2006, a $68.7 million increase from the prior year. The year-over-year increase primarily reflects the higher profitability of the M-I SWACO joint venture and, to a lesser extent, improved earnings reported by CE Franklin Ltd.
2005 versus 2004
     Consolidated revenues increased to $5.6 billion for the year ended December 31, 2005, 26 percent above the prior year period. The majority of the year-over-year dollar variance was reported in the Oilfield segment primarily attributable to higher worldwide drilling activity. On a geographic basis, two-thirds of the revenue improvement was generated in North America impacted by a combination of increased land-based drilling activity, strong demand for tubular products and improved pricing. Increased business volumes in markets outside North America also contributed to the year-over-year revenue variance, reflecting higher customer spending levels and the impact of new contract awards.
     Gross profit totaled $1.7 billion, or 30 percent of revenues, less than one percentage point below the gross profit margins generated in 2004. The modest decline in gross profit margins reflects an increased proportion of Distribution segment sales, which historically generate lower margins than the Oilfield operations. To a lesser extent, gross profit margin deterioration reported in the Distribution segment also contributed to the reduction in consolidated gross profit margins. On an absolute dollar basis, gross profit was $333.2 million above the prior year period primarily reflecting the increased sales volumes in the Oilfield operations.
     Operating expenses, consisting of selling, general and administrative expenses, increased $101.4 million from the amount reported in the 2004 fiscal year. The year-over-year operating expense variance was impacted by litigation-related charges, including $5.6 million recorded in 2005 and $28.8 million recognized during 2004, related to the settlement, legal fees and other costs directly associated with a patent infringement case. Excluding the litigation-related charges, operating expenses increased $124.6 million on an absolute dollar basis, but decreased two percentage points from the prior year period, as a percentage of revenues. The majority of the absolute dollar increase was attributable to variable costs directly associated with the improved business volumes, including increased investment in personnel and infrastructure. To a lesser extent, increased employee profit-sharing amounts directly attributable to the reported profitability levels and stock-based compensation expense associated with restricted stock awards also contributed to the year-over-year operating expense growth.
     Net interest expense, which represents interest expense less interest income, totaled $42.8 million in 2005. Net interest expense increased $5.3 million from the 2004 level reflecting higher average debt levels between the periods and, to a lesser extent, an increase in variable interest rates.
     The effective tax rate approximated 32 percent, which was comparable to the level reported in 2004, but below the U.S. statutory rate. The effective tax rate was lower than the U.S. statutory rate due to the impact of M-I SWACO’s U.S. partnership earnings for which the minority partner is directly responsible for its related income taxes. The Company properly consolidates the pretax income related to the minority partner’s share of U.S. partnership earnings but excludes the related tax provision.
     Minority interests reflect the portion of the results of majority-owned operations which are applicable to the minority interest partners. Minority interests totaled $122.8 million in 2005, a $33.6 million increase from 2004. The year-over-year increase primarily reflects the higher profitability of the M-I SWACO joint venture and, to a lesser extent, improved earnings reported by CE Franklin Ltd.

Liquidity and Capital Resources
General
     At December 31, 2006, cash and cash equivalents equaled $80.4 million. During 2006, the Company generated $287.2 million of cash flows from operations, which is $67.8 million above the amount reported in 2005. Increased profitability levels experienced by the Company were offset by higher working capital investment required to support the significant increase in business volumes.
     In 2006, cash flows used in investing activities totaled $470.9 million, primarily consisting of amounts required to fund capital expenditures and acquisitions. The Company invested $257.7 million in property, plant and equipment, net of cash proceeds associated with certain asset disposals, as well as, funds received related to property insurance claims. Acquisition funding, which primarily related to the purchase of Specialised Petroleum Services Group Limited and Epcon Offshore AS, resulted in cash outflows of $226.7 million in 2006.
     Projected net capital expenditures for 2007 are expected to approximate $285 million. The modest increase in planned investment year-over-year is associated with growth in spending for the rental equipment fleet to support market expansion efforts in the United States and certain key international regions. The majority of the 2007 capital spending consists of investment for routine additions of rental tool and manufacturing equipment to support the Company’s operations and maintenance of the Company’s capital equipment base.
     Cash flows provided by financing activities totaled $199.5 million in 2006. Due to the higher business volumes, which impacted the required investment in working capital, cash flows from operations were not sufficient to fund investing activities, repurchases under the Company’s stock buyback program and dividend payments. This resulted in incremental borrowings of $346.8 million financed by the issuance of publicly-traded debt instruments and, to a lesser extent, the negotiation of foreign-currency denominated term loans with two financial institutions.
     The Company’s primary internal source of liquidity is cash flow generated from operations. Cash flow generated from operations is primarily influenced by the level of worldwide drilling activity, which affects profitability levels and working capital requirements. Capacity under revolving credit agreements is also available, if necessary, to fund operating or investing activities. As of December 31, 2006, the Company had $235.0 million of capacity available under its U.S. revolving credit facilities for future operating, investing or financing needs. The Company also has revolving credit facilities in place outside of the United States, which are generally used to fund local operating needs. At the end of fiscal 2006, the Company had available borrowing capacity of $112.7 million under the non-U.S. borrowing facilities.
     The Company’s external sources of liquidity include debt and equity financing in the public capital markets, if needed. The Company carries an investment-grade credit rating with recognized rating agencies, generally providing the Company with access to debt markets. The Company’s overall borrowing capacity is, in part, dependent on maintaining compliance with financial covenants under the various credit agreements. As of December 31, 2006, the Company was well within the covenant compliance thresholds under its various loan indentures, as amended, providing the ability to access available borrowing capacity. Management believes funds generated by operations, amounts available under existing credit facilities and external sources of liquidity will be sufficient to finance capital expenditures and working capital needs of the existing operations for the foreseeable future.
     Management continues to evaluate opportunities to acquire products or businesses complementary to the Company’s operations. Additional acquisitions, if they arise, may involve the use of cash or, depending upon the size and terms of the acquisition, may require debt or equity financing.
     During 2005, the Company’s Board of Directors approved a quarterly cash dividend program. On February 7, 2007, the Company’s Board of Directors increased the quarterly cash dividend to $0.10 per share. The current annualized payout of approximately $80 million is expected to be funded with cash flows from operations and, if necessary, amounts available under existing credit facilities. The level of future dividend payments will be at the discretion of the Company’s Board of Directors and will depend upon the Company’s financial condition, earnings, cash flows, compliance with certain debt covenants and other relevant factors.

     In October 2005, the Company’s Board of Directors authorized a share repurchase program that allows for the purchase of up to 20 million shares of the Company’s common stock, subject to regulatory issues, market considerations and other relevant factors. As of December 31, 2006, the Company had 17.3 million shares remaining under the current authorizations. Future repurchases under the program may be executed from time to time in the open market or in privately negotiated transactions and will be funded with cash flows from operations or amounts available under existing credit facilities.
     The Company believes that it has sufficient existing manufacturing capacity to meet current demand for its products and services. Additionally, inflation has had a modest impact on the Company’s financial results in the three most recent fiscal years, with the Company experiencing a slight escalation in wages, transportation costs, as well as, petrochemical, steel and other commodity prices during 2006. The Company expects to be able to continue to offset the impact of cost inflation going forward through productivity gains and price increases.
     The Company has not engaged in off-balance sheet financing arrangements through special purpose entities, and the consolidation of the Company’s minority ownership positions would not result in an increase in reported leverage ratios. The Company has no contractual arrangements in place that could result in the issuance of additional shares of the Company’s common stock at a future date other than the Company’s stock-based compensation program, which is discussed in Note 1, “Summary of Significant Accounting Policies,” and Note 15, “Long-Term Incentive Compensation.”

     In the normal course of business, the Company enters into lease agreements with cancellation provisions as well as agreements with initial terms of less than one year. The costs related to these leases have been reflected in rent expense, which totaled $127.1 million in 2006, but have been appropriately excluded from the future minimum payments presented in the table above. Amounts related to commitments under capital lease agreements, as well as pension and other postretirement obligations, were immaterial for the periods presented.
Standby Letters of Credit
     In the normal course of business with customers, vendors and others, the Company is contingently liable for performance under standby letters of credit and bid, performance and surety bonds. Certain of these outstanding instruments guarantee payment to insurance companies which reinsure certain liability coverages of the Company’s insurance captive. Excluding the impact of these instruments, for which $19.4 million of related liabilities are reflected in the accompanying consolidated balance sheet, the Company was contingently liable for approximately $78.3 million of standby letters of credit and bid, performance and surety bonds at December 31, 2006. Management does not expect any material amounts to be drawn on these instruments.
Insurance
     The Company maintains insurance coverage for various aspects of its business and operations. The Company has elected to retain a portion of losses that occur through the use of deductibles and retentions under its insurance programs. 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 management believes that amounts accrued in the accompanying consolidated financial statements are adequate for expected liabilities arising from the Company’s portion of losses, estimates of these liabilities may change as circumstances develop.

Litigation
Rose Dove Egle v. John M. Egle, et al.
     In April 1997, the Company acquired all of the equity interests in Tri-Tech Fishing Services, L.L.C. (“Tri-Tech”) in exchange for cash consideration of approximately $20.4 million (the “Transaction”).
     In August 1998, the Company was added as a defendant in a First Amended Petition filed in the 15th Judicial District Court, Parish of Lafayette, Louisiana entitled Rose Dove Egle v. John M. Egle, et al. In the amended petition, the plaintiffs alleged that, due to an improper conveyance of ownership interest by the Tri-Tech majority partner prior to the Transaction, Smith purchased a portion of its equity interest from individuals who were not legally entitled to their Tri-Tech shares. The suit was tried in the first quarter of 2004, and a jury verdict of approximately $4.8 million was rendered in favor of the plaintiffs. The Company has appealed the verdict and does not anticipate a ruling until the third quarter of 2007. Based upon the facts and circumstances and the opinion of outside legal counsel, management believes that an unfavorable outcome on this matter is not probable at this time. Accordingly, the Company has not recognized a loss provision in the accompanying consolidated financial statements.
Other
     The Company is a defendant in various other legal proceedings arising in the ordinary course of business. In the opinion of management, these matters will not have a material adverse effect on the Company’s consolidated financial position or results of operations.
Environmental
     The Company routinely establishes and reviews the adequacy of reserves for estimated future environmental clean-up costs for properties currently or previously operated by the Company.
     As of December 31, 2006, the Company’s environmental reserve totaled $8.4 million. This amount reflects the future undiscounted estimated exposure related to identified properties, without regard to indemnifications from former owners. While actual future environmental costs may differ from estimated liabilities recorded at December 31, 2006, the Company does not believe that these differences will have a material impact on the Company’s financial position or results of operations.

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. The preparation of these financial statements requires management 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 on-going 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 describes significant judgments and estimates used in the preparation of its consolidated financial statements:
Allowance for doubtful accounts. The Company extends credit to customers and other parties in the normal course of business. Management regularly reviews outstanding receivables and provides for estimated losses through an allowance for doubtful accounts. In evaluating the level of established reserves, management makes judgments regarding the parties’ ability to make required payments, economic events and other factors. As the financial condition of these parties change, circumstances develop or additional information becomes available, adjustments to the allowance for doubtful accounts may be required.
Inventory reserves. The Company has made significant investments in inventory to service its customers around the world. On a routine basis, the Company uses judgments in determining the level of reserves required to state inventory at the lower of cost or market. Management’s estimates are primarily influenced by technological innovations, market fundamentals and the physical condition of products. Changes in these or other factors may result in adjustments to the carrying value of inventory.
Goodwill. The Company has acquired a number of operations during the past decade, which has resulted in the recording of a material amount of goodwill. Under SFAS No. 142, “Goodwill and Other Intangible Assets,” the Company is required to perform an annual goodwill impairment evaluation, which is largely influenced by future cash flow projections. Estimating future cash flows of the Company’s operations requires management to make judgments about future operating results and working capital requirements. Although the majority of the goodwill relates to the Company’s Oilfield operations, $40.7 million of goodwill relates to Distribution transactions. Changes in cash flow assumptions or other factors that negatively impact the fair value of the operations would influence the evaluation and may result in the determination that a portion of the goodwill is impaired when the annual analysis is performed.
Self-Insurance. The Company maintains insurance coverage for various aspects of its business and operations. The Company retains a portion of losses that occur through the use of deductibles and retentions under self-insurance programs. Management regularly reviews estimates of reported and unreported claims and provides for losses through insurance reserves. As claims develop and additional information becomes available, adjustments to loss reserves may be required.
Income taxes. Deferred tax assets and liabilities are recognized for 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. In certain cases, management has established reserves to reduce deferred tax assets to estimated realizable value. If tax regulations, operating results or the ability to implement tax planning strategies vary, adjustments to the carrying value of deferred tax assets and liabilities may be required.
Environmental Obligations. The Company records liabilities for environmental obligations when remedial efforts are probable and the costs can be reasonably estimated. Management’s estimates are based on currently enacted laws and regulations. As more information becomes available or environmental laws and regulations change, such liabilities may be required to be adjusted. Additionally, in connection with acquisitions, the Company generally obtains indemnifications from the seller related to environmental matters. If the indemnifying parties do not fulfill their obligations, adjustments of recorded amounts may be required.

Recent Accounting Pronouncements
     From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) that are adopted by the Company as of the specified effective date.
     In July 2006, the FASB issued Interpretation No. 48, “Accounting for Uncertainty in Income Taxes — an interpretation of FASB Statement No. 109” (“FIN 48”), which clarifies the accounting and disclosure requirements for uncertainty in tax positions. FIN 48 requires a two-step approach to evaluate tax positions and determine if they should be recognized in the financial statements. This approach involves recognizing any tax positions that are “more likely than not” to occur and then measuring those positions to determine if they are recognizable in the financial statements. The provisions of FIN 48 are effective and the Company will adopt the interpretation in the first quarter of 2007. Based on our evaluation as of December 31, 2006, we do not expect the adoption of FIN 48 to have a material impact on our consolidated financial statements.
     In September 2006, the FASB issued Statement of Financial Accounting Standards (“SFAS”) No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans — an amendment of FASB Statements No. 87, 88, 106, and 132(R)” (“SFAS 158”). Effective December 31, 2006, SFAS 158 requires recognition of the funded status of an entity’s defined benefit pension and other postretirement benefit plans as an asset or liability in the Company’s consolidated balance sheet. Subsequent changes to the funded status are to be recognized through stockholders’ equity as a component of comprehensive income. In addition, for fiscal years ending after December 15, 2008, SFAS 158 requires the adoption of certain provisions related to the measurement date of obligations and assets used to calculate the funded status. The December 31, 2006 adoption of the recognition provisions of SFAS 158 did not have a material impact on the Company’s consolidated financial position or results of operations. We do not expect the remaining elements of the Statement to have a material impact on our consolidated financial statements.
     Management believes the impact of other recently issued standards, which are not yet effective, will not have a material impact on the Company’s consolidated financial statements upon adoption.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk
     The Company is exposed to market risks from changes in interest rates and foreign exchange rates and enters into various hedging transactions to mitigate these risks. The Company does not use financial instruments for trading or speculative purposes. See Note 10, “Financial Instruments,” to the Consolidated Financial Statements for additional discussion of hedging instruments.
     The Company’s exposure to interest rate changes is managed through the use of a combination of fixed and floating rate debt and by entering into interest rate contracts, from time to time, on a portion of its long-term borrowings. The Company had no interest rate contracts outstanding as of December 31, 2006 and 2005. At December 31, 2006, 35 percent of the Company’s long-term debt carried a variable interest rate. Management believes that significant interest rate changes will not have a material near-term impact on the Company’s future earnings or cash flows.
     The Company’s exposure to changes in foreign exchange rates is managed primarily through the use of forward exchange contracts. These contracts increase or decrease in value as foreign exchange rates change, to protect the value of the underlying transactions denominated in foreign currencies. All currency contracts are components of the Company’s hedging program and are entered into for the sole purpose of hedging an existing or anticipated currency exposure. The gains and losses on these contracts offset changes in the value of the related exposures. The terms of these contracts generally do not exceed two years. As of December 31, 2006, the notional amounts of fair value hedge contracts and cash flow hedge contracts outstanding were $126.9 million and $20.8 million, respectively, and the fair value was less than the notional amount of these contracts by $0.2 million. As of December 31, 2005, the notional amount of fair value hedge contracts and cash flow hedge contracts outstanding were $99.8 million and $40.4 million, respectively, and the fair value was less than the notional amount of these contracts by $1.7 million. In some areas, where hedging is not cost effective, the Company addresses foreign currency exposure utilizing working capital management.
     The Company utilizes a “Value-at-Risk” (“VAR”) model to determine the maximum potential one-day loss in the fair value of its foreign exchange sensitive financial instruments. The VAR model estimates were made assuming normal market conditions and a 95 percent confidence level. The Company’s VAR computations are based on the historical price movements in various currencies (a “historical” simulation) during the year. The model includes all of the Company’s foreign exchange derivative contracts. Anticipated transactions, firm commitments and assets and liabilities denominated in foreign currencies, which certain of these instruments are intended to hedge, were excluded from the model. The VAR model is a risk analysis tool and does not purport to represent actual losses in fair value that will be incurred by the Company, nor does it consider the potential effect of favorable changes in market factors. The estimated maximum potential one-day loss in fair value of currency sensitive instruments, calculated using the VAR model, was not material to the Company’s financial position or results of operations.

Management’s Report on Internal Control Over Financial Reporting
Management of the Company is responsible for establishing and maintaining effective internal control over financial reporting as defined in Rule 13a — 15(f) under the Securities Exchange Act of 1934. The Company’s internal control over financial reporting is designed to provide reasonable, not absolute, assurance to the Company’s management and board of directors regarding the preparation and fair presentation of published financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable, not absolute, assurance with respect to financial statement preparation and presentation.
The Company’s management assessed the effectiveness of the Company’s internal control over financial reporting based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, management believes that the Company’s internal control over financial reporting was effective as of December 31, 2006.
Management’s assessment of the effectiveness of internal control over financial reporting as of December 31, 2006 has been audited by Deloitte & Touche LLP, the independent registered public accounting firm who also audited the Company’s consolidated financial statements. The Deloitte & Touche LLP attestation report on management’s assessment of the Company’s internal control over financial reporting appears on page 27 of this Annual Report on Form 10-K.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Directors and Stockholders of Smith International, Inc.:
We have audited management’s assessment, included in the accompanying Management’s Report on Internal Control Over Financial Reporting, that Smith International, Inc. and subsidiaries (the “Company”) maintained effective internal control over financial reporting as of December 31, 2006, 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 maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on management’s assessment and an opinion on the effectiveness of the Company’s internal control over financial reporting based on our audit.
We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, evaluating management’s assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides 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, management’s assessment that the Company maintained effective internal control over financial reporting as of December 31, 2006, is fairly stated, in all material respects, based on the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2006, based on the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements and financial statement schedule as of and for the year ended December 31, 2006 of the Company and our report dated February 28, 2007 expressed an unqualified opinion on those financial statements and financial statement schedule and included an explanatory paragraph regarding the Company’s adoption of new accounting standards.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Directors and Stockholders of Smith International, Inc.:
We have audited the accompanying consolidated balance sheets of Smith International, Inc. and subsidiaries (the “Company”) as of December 31, 2006 and 2005, and the related consolidated statements of operations, stockholders’ equity and comprehensive income, and cash flows for each of the three years in the period ended December 31, 2006. Our audits also included the financial statement schedule listed in Part IV, Item 15 (a) (2). These financial statements and the financial statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on the financial statements and financial statement schedule based on our audits.
We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.
In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of Smith International, Inc. and subsidiaries as of December 31, 2006 and 2005, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2006, 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.
As discussed in Note 1 to the consolidated financial statements, the Company adopted Statement of Financial Accounting Standards (“SFAS”) No. 123r, “Share-Based Payment” as of January 1, 2006 and SFAS No. 158, “Employers Accounting for Defined Benefit Pension and Other Postretirement Plans” as of December 31, 2006.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of the Company’s internal control over financial reporting as of December 31, 2006, based on the criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 28, 2007 expressed an unqualified opinion on management’s assessment of the effectiveness of the Company’s internal control over financial reporting and an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

SMITH INTERNATIONAL, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(All dollar amounts are expressed in thousands, unless otherwise noted)
1. Summary of Significant Accounting Policies
Basis of Presentation
     Smith International, Inc. (“Smith” or the “Company”) provides premium products and services to the oil and gas exploration and production industry. The accompanying consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States and all applicable financial statement rules and regulations of the Securities and Exchange Commission (the “Commission”). Management believes the consolidated financial statements present fairly the financial position, results of operations and cash flows of the Company as of the dates indicated.
     The consolidated financial statements include the accounts of the Company and all wholly and majority-owned subsidiaries, after the elimination of all significant intercompany accounts and transactions. Investments in affiliates in which ownership interest ranges from 20 to 50 percent, and the Company exercises significant influence over operating and financial policies, are accounted for on the equity method. All other investments are carried at cost, which does not exceed the estimated net realizable value of such investments.
Stock Split
     In July 2005, the Company’s Board of Directors approved a two-for-one stock split, which was effected in the form of a stock dividend. Stockholders of record as of August 5, 2005 were entitled to the dividend, which was distributed on August 24, 2005. Unless otherwise noted, the 2004 share and earnings per share amounts included in the accompanying consolidated financial statements and related notes have been restated for the effect of the stock split.
Use of Estimates
     Preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosed amounts of contingent assets and liabilities and the reported amounts of revenues and expenses. Management believes the most significant estimates and assumptions are associated with the valuation of accounts receivable, inventories, goodwill and deferred taxes as well as the determination of liabilities related to environmental obligations and self-insurance programs. If the underlying estimates and assumptions, upon which the financial statements are based, change in future periods, actual amounts may differ from those included in the accompanying consolidated financial statements.
Cash and Cash Equivalents
     The Company considers all highly liquid financial instruments purchased with an original maturity of three months or less to be cash equivalents.
Allowance for Doubtful Accounts
     The Company maintains an allowance for doubtful accounts to provide for receivables which may ultimately be uncollectible. Reserves are determined in light of a number of factors including customer specific conditions, economic events and the Company’s historical loss experience. At December 31, 2006 and 2005, the allowance for doubtful accounts was $16.7 million and $13.9 million, respectively.
Inventories
     Inventories are stated at the lower of cost or market. Cost is determined using the average cost method for the majority of the Company’s inventories; however, certain of the Company’s U.S.-based inventories are valued utilizing the last-in, first-out (“LIFO”) method. Inventory costs consist of materials, labor and factory overhead.

Table of Contents

Fixed Assets
     Fixed assets, consisting of rental equipment and property, plant and equipment, are stated at cost, net of accumulated depreciation. The Company computes depreciation on fixed assets using principally the straight-line method; however, for income tax purposes, accelerated methods of depreciation are used. The estimated useful lives used in computing depreciation generally range from 20 to 40 years for buildings, three to 25 years for machinery and equipment, and five to ten years for rental equipment. Leasehold improvements are amortized over the initial lease term or the estimated useful lives of the improvements, whichever is shorter. Depreciation expense for the years ended December 31, 2006, 2005 and 2004 was $129.6 million, $106.8 million and $96.9 million, respectively.
     Costs of major renewals and betterments are capitalized as fixed assets; however, expenditures for maintenance, repairs and minor improvements are charged to expense when incurred. When fixed assets are sold or retired, the remaining cost and related accumulated depreciation are removed from the accounts and the resulting gain or loss is included in the consolidated statement of operations.
Goodwill and Other Intangible Assets
     Goodwill represents the excess of cost over the fair value of net assets acquired. Recorded goodwill balances are not amortized but, instead, are evaluated for impairment annually or more frequently if circumstances indicate that an impairment may exist. The goodwill valuation, which is prepared during the first quarter of each calendar year, is largely influenced by projected future cash flows and, therefore, is significantly impacted by estimates and judgments.
     The Company amortizes other identifiable intangible assets on a straight-line basis over the periods expected to be benefited, ranging from three to 27 years. The components of these other intangible assets generally consist of patents, license agreements, non-compete agreements, trademarks and customer lists and contracts.
Impairment of Long-Lived Assets
     Management reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If an evaluation is required, the estimated undiscounted future cash flows associated with the asset will be compared to the asset’s carrying amount to determine if an impairment exists.
Environmental Obligations
     Expenditures for environmental obligations that relate to current operations are expensed or capitalized, as appropriate. Liabilities are recorded when environmental clean-up efforts are probable and their cost is reasonably estimated, and are adjusted as further information is obtained. Such estimates are based on currently enacted laws and regulations and are not discounted to present value.
Liabilities Related to Self-Insurance Programs
     The Company is self-insured for certain casualty and employee medical insurance liabilities of its U.S. operations. Expenditures for casualty and medical claims are recorded when incurred after taking into consideration recoveries available under stop-loss insurance policies. Additionally, reserves are established to provide for the estimated cost of settling known claims as well as medical and casualty exposures projected to have been incurred but not yet reported.
Foreign Currency Translation and Transactions
     Gains and losses resulting from balance sheet translation of operations outside the United States where the applicable foreign currency is the functional currency are included as a component of accumulated other comprehensive income within stockholders’ equity. Gains and losses resulting from balance sheet translation of operations outside the United States where the U.S. dollar is the functional currency are included in the consolidated statements of operations.
     Gains and losses resulting from foreign currency transactions, excluding cash flow hedges discussed below, are recognized currently in the consolidated statements of operations.

Financial Instruments
     The nature of the Company’s business activities involves the management of various financial and market risks, including those related to changes in currency exchange rates and interest rates. The Company utilizes derivative financial instruments such as foreign exchange contracts, foreign exchange options and interest rate contracts to mitigate or eliminate certain of those risks. The Company does not enter into derivative instruments for speculative purposes.
     The Company records changes in fair market value related to fair value hedges, which includes foreign exchange contracts, to general and administrative expenses in the consolidated statements of operations. Changes in value related to cash flow hedges, which includes foreign exchange contracts, foreign exchange options and interest rate swaps, are recorded in accumulated other comprehensive income and are recognized in the consolidated statement of operations when the hedged item affects earnings.
Income Taxes
     The Company accounts for income taxes using an asset and liability approach for financial accounting and income tax reporting based on enacted tax rates. Deferred tax assets are reduced by a valuation allowance when it is more likely than not that some portion, or all, of the deferred tax assets will not be realized.
Revenue Recognition
     The Company’s revenues, which are composed of product, rental, service and other revenues, are generally subject to contractual arrangements which specify price and general terms and conditions. The Company recognizes product revenues, net of applicable provisions for returns, when title and the related risk of loss transfers to the customer. Rental, service and other revenues are recorded when such services are performed and collectibility is reasonably assured.
Minority Interests
     The Company records minority interest expense which reflects the portion of the earnings of majority-owned operations which are applicable to the minority interest partners. The minority interest amount primarily represents the share of the M-I SWACO profits associated with the minority partner’s 40 percent interest in those operations. To a lesser extent, minority interests include the portion of CE Franklin Ltd. and United Engineering Services LLC earnings applicable to the respective minority shareholders.
Long-term Incentive Compensation
     The Company’s Board of Directors and its stockholders have authorized a long-term incentive plan for the benefit of key employees. Although the Plan provides for the issuance of various stock-based awards, the Compensation Committee has elected to issue restricted stock units and, prior to December, 2005, stock option awards.
     Restricted stock units are considered compensatory awards and compensation expense related to these units is recognized over the established vesting period in the accompanying consolidated financial statements.
     Accounting for the stock option program however, was impacted by the mandatory adoption of Statement of Financial Accounting Standards (“SFAS”) No. 123r, “Share-Based Payment,” (“SFAS No. 123r”) on January 1, 2006. In connection with the implementation, we utilized the modified prospective method; and, accordingly, results for prior periods have not been restated. Prior to January 1, 2006, companies could continue to apply Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees” (“APB No. 25”), and related interpretations in accounting for its stock option program. Accordingly, for fiscal periods prior to January 1, 2006, the Company has elected to make pro forma footnote disclosures rather than recognizing the related compensation expense for stock option awards in the consolidated financial statements.

     Had the Company elected to apply the accounting standards of SFAS No. 123, “Accounting for Stock-Based Compensation”, the Company’s net income and earnings per share would have approximated the pro forma amounts indicated below (in thousands, except per share data):

Recent Accounting Pronouncements
     From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) that are adopted by the Company as of the specified effective date.
     In July 2006, the FASB issued Interpretation No. 48, “Accounting for Uncertainty in Income Taxes – an interpretation of FASB Statement No. 109” (“FIN 48”), which clarifies the accounting and disclosure requirements for uncertainty in tax positions. FIN 48 requires a two-step approach to evaluate tax positions and determine if they should be recognized in the financial statements. This approach involves recognizing any tax positions that are “more likely than not” to occur and then measuring those positions to determine if they are recognizable in the financial statements. The provisions of FIN 48 are effective and the Company will adopt the interpretation in the first quarter of 2007. Based on our evaluation as of December 31, 2006, we do not expect the adoption of FIN 48 to have a material impact on our consolidated financial statements.
     In September 2006, the FASB issued SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans – an amendment of FASB Statements No. 87, 88, 106, and 132(R)” (“SFAS 158”). Effective December 31, 2006, SFAS 158 requires recognition of the funded status of an entity’s defined benefit pension and other postretirement benefit plans as an asset or liability in the Company’s consolidated balance sheet. Subsequent changes to the funded status are to be recognized through stockholders’ equity as a component of comprehensive income. In addition, for fiscal years ending after December 15, 2008, SFAS 158 requires the adoption of certain provisions related to the measurement date of obligations and assets used to calculate the funded status. The December 31, 2006 adoption of the recognition provisions of SFAS 158 did not have a material impact on the Company’s consolidated financial position or results of operations. We do not expect the remaining elements of the Statement to have a material impact on our consolidated financial statements.
     Management believes the impact of other recently issued standards, which are not yet effective, will not have a material impact on the Company’s consolidated financial statements upon adoption.
2. Patent Litigation
     In September 2002, the Company was served with a complaint in the U.S. District Court for the Eastern District of Texas, Sherman Division entitled Halliburton Energy Services, Inc. v. Smith International, Inc. This lawsuit was a patent infringement claim alleging that certain roller cone drill bits made by the Company infringed several U.S. patents owned by Halliburton. The case was tried in the second quarter of 2004, and the Company recorded a litigation-related charge based on management’s best estimate of its potential exposure. This 2004 charge, which consisted of an estimated loss provision, legal fees and other directly related costs, totaled $31.4 million, or $20.4 million on an after-tax basis.
     In December 2005, the Company reached final settlement with Halliburton regarding all outstanding drill bit patent litigation matters. In connection with the settlement, the Company recorded an additional $5.6 million litigation-related charge, or $3.7 million on an after-tax basis, which included legal fees and other costs directly associated with the settlement.

3. Business Combinations
     During 2006, the Company completed seven acquisitions in exchange for aggregate cash consideration of $226.7 million and the assumption of certain liabilities. The 2006 transactions primarily consist of the following:
On February 23, 2006, M-I SWACO acquired Epcon Offshore AS (“Epcon”) in exchange for cash consideration of approximately $44.9 million. Epcon, based in Porsgrunn, Norway, is a global provider of proprietary water treatment technology designed to optimize the removal of hydrocarbons from water generated during the oil and gas production process.
On August 3, 2006, M-I SWACO acquired Specialised Petroleum Services Group Limited (“SPS”) in exchange for cash consideration of approximately $165.4 million. SPS, based in Aberdeen, Scotland, is a global provider of patented well-bore clean-up products and engineering services used to remove debris from the wellbore to facilitate improved well production.
     The excess of the purchase price over the estimated fair value of the net assets acquired amounted to $129.3 million, which has been recorded as goodwill in the accompanying consolidated balance sheet. Based on the structure of the transactions, the majority of the goodwill related to the 2006 acquisitions is not expected to be deductible for tax purposes. The purchase price allocation related to the 2006 acquisitions is based on preliminary information and is subject to change when additional data concerning final asset and liability valuations is obtained; however, material changes in the preliminary allocations are not anticipated by management.
     During 2005, the Company completed six acquisitions in exchange for aggregate cash consideration of $81.3 million and the assumption of certain liabilities. The 2005 transactions primarily consist of the following:
On August 17, 2005, Smith Services acquired certain operating assets of Tubular Technology, Inc. and associated companies for cash consideration of $23.2 million. The acquired operations provide a full range of products and services used during the installation of corrosion-resistant alloy tubulars and also offer proprietary products and technical services used during the completion-phase of oil and gas wells, primarily to customers in the U.S. Gulf Coast region.
On November 1, 2005, Smith Services acquired certain operating assets of Nunez Oil Field Pipe, Ltd. and associated companies for cash consideration of $41.4 million. The acquired companies rent and repair premium drill pipe, drill collars, and blow-out preventers and perform machine shop and related inspection services in the United States.
     The excess of the purchase price over the estimated fair value of the net assets acquired amounted to $23.4 million, which has been recorded as goodwill in the accompanying consolidated balance sheet.
     During 2004, the Company completed six acquisitions in exchange for aggregate cash consideration of $49.2 million and the assumption of certain liabilities. In addition, cash payments of $23.2 million were made during the year to former shareholders of businesses acquired in 2002 to fund amounts due under earn-out arrangements and repay seller-financed notes. The 2004 transactions primarily consist of the following:
On January 31, 2004, M-I SWACO acquired certain specialty chemical assets of Fortum Oil and Gas OY for cash consideration of $11.4 million. The acquired operations, formerly based in Finland, manufacture and market specialty chemical products which improve hydrocarbon flow rates.
On July 31, 2004, Smith Services acquired certain operating assets of CanFish Services for cash consideration of $17.5 million. The acquired operations provide fishing, milling, casing exit, pipe recovery and related wireline services in the United States and Canada.
     The excess of the purchase price over the estimated fair value of the net assets acquired amounted to $15.9 million and has been recorded as goodwill in the accompanying consolidated balance sheet.
     These acquisitions have been recorded using the purchase method of accounting and, accordingly, the acquired operations have been included in the results of operations since the date of acquisition. Pro forma results of operations have not been presented because the effect of these acquisitions was not material to the Company’s consolidated financial statements.

4. Business Dispositions
     From time to time, the Company divests of select business operations. During the years ended December 31, 2006 and 2005, the Company completed the disposition of its ownership interest in certain Oilfield operations in exchange for aggregate cash consideration of $13.5 million and $20.5 million, respectively. These transactions resulted in an aggregate pre-tax gain of approximately $6.5 million and $5.9 million for the year’s ended December 31, 2006, and 2005, respectively. The impact of these dispositions has been reflected as a reduction in general and administrative expenses in the accompanying consolidated statements of operations for the respective periods. After taking into consideration taxes and minority interests, the transactions impacted net income by $3.2 million and $3.7 million for the years ended December 31, 2006 and 2005, respectively.
5. Earnings Per Share
     Basic earnings per share (“EPS”) is computed using the weighted average number of common shares outstanding during the period. Diluted EPS gives effect to the potential dilution of earnings which could have occurred if additional shares were issued for stock option and restricted stock awards under the treasury stock method. An immaterial number of stock awards, which were issued at exercise prices in excess of the year-end stock price, were excluded from the 2004 and 2006 calculations as the instruments would have an anti-dilutive effect on the calculation. The following schedule reconciles the income and shares used in the basic and diluted EPS computations (in thousands, except per share data):
                         
    2006     2005     2004

  $ 1,457,371     $ 1,059,992  
 
           
     During 2006, the Company recorded additional LIFO reserves of $18.9 million, primarily related to the revaluation of on-hand inventories to current standards, largely reflecting higher manufacturing costs in the Oilfield segment.

     Short-term borrowings consist of amounts outstanding under lines of credit and short-term notes. Certain subsidiaries of the Company have unsecured credit facilities with non-U.S. banks aggregating $202.0 million with $112.7 million of additional borrowing capacity available under these facilities at December 31, 2006. These borrowings had a weighted average interest rate of 7.6 percent and 7.0 percent at December 31, 2006 and 2005, respectively.
     Additionally, the Senior Notes maturing in the third quarter of 2007 are classified as current indebtedness and account for the majority of the current portion of long-term debt at December 31, 2006.
     In addition to the credit facilities discussed above, the Company has a $400 million unsecured revolving credit facility provided by a syndicate of nine financial institutions. The revolving credit agreement (the “Agreement”) allows for the election of interest at a base rate, or a Eurodollar rate ranging from LIBOR plus 40 to 50 basis points depending on the borrowing levels drawn under the facility. The Agreement also requires the payment of a quarterly commitment fee of 10 basis points on the unutilized portion of the facility and compliance with certain customary covenants, including a 40 percent debt-to-total capitalization limitation. As of December 31, 2006, the Company had $160.5 million drawn and $4.5 million of letters of credit issued under the facility, resulting in additional borrowing capacity of $235.0 million.
     The 6.0 percent, 6.75 percent and 7.0 percent Senior Notes (the “Public Notes”) are unsecured obligations of the Company issued under an Indenture dated September 8, 1997. The Indenture contains no financial covenants, nor any restrictions related to the payment of cash dividends to common stockholders. The Company’s Public Notes are redeemable by the Company, in whole or in part, at any time prior to maturity at a redemption price equal to accrued interest plus the greater of the principal amount or the present value of the remaining principal and interest payments.
     During 2006, the Company entered into two foreign currency denominated term loans (the “Term Loans”) to provide local financing for the Epcon and SPS transactions. The Term Loans are unsecured and require compliance with certain customary covenants, including debt-to-total capitalization and debt-to-EBITDA limitations. The Term Loans can be prepaid, in whole or in part, without penalty subject to required notice periods and compliance with minimum prepayment amounts.
     The Company was in compliance with its loan covenants under the various loan indentures, as amended, at December 31, 2006.
10. Financial Instruments
Foreign Currency Contracts
     The Company enters into spot and forward contracts as a hedge against foreign currency denominated assets and liabilities and foreign currency commitments. The term of these contracts generally do not exceed two years. For fair value hedges, realized and unrealized gains and losses are recognized currently through earnings, and the resulting amounts generally offset foreign exchange gains or losses on the related accounts. The Company recognized expense of approximately $5.9 million, $4.4 million and $2.4 million in 2006, 2005 and 2004, respectively, related to net realized and unrealized losses on fair value hedge contracts. Gains or losses on designated cash flow hedge contracts are deferred to accumulated other comprehensive income and recognized in the consolidated statement of operations when the hedged item affects earnings. The Company recognized expense of $1.6 million and $0.9 million in 2006 and 2005, respectively, and earnings of $4.2 million in 2004, related to cash flow hedge contracts. As of December 31, 2006, the notional amounts of fair value hedge contracts and cash flow hedge contracts outstanding were $126.9 million and $20.8 million, respectively, and the fair value was less than the notional amount of these contracts by $0.2 million. As of December 31, 2005, the notional amount of fair value hedge contracts and cash flow hedge contracts outstanding were $99.8 million and $40.4 million, respectively, and the fair value was less than the notional amount of these contracts by $1.7 million.
Fair Value of Other Financial Instruments
     The recorded and fair values of long-term debt at December 31 are as follows:
                                 
    2006   2005
    Recorded   Fair   Recorded   Fair
    Value   Value   Value   Value
Long-term Debt
  $ 999,325     $ 1,015,062     $ 622,333     $ 646,013  
     The fair value of publicly-traded long-term debt was primarily determined using quoted market prices. The fair value of the remaining financial instruments, including cash and cash equivalents, receivables, payables and short-term and bank borrowings, approximates the carrying value due to the nature of these instruments.

     At December 31, 2006, the accompanying consolidated financial statements include $18.4 million of deferred tax assets associated with operating loss carryforwards in tax jurisdictions outside the United States. Although a significant portion of these losses will carryforward indefinitely and are available to reduce future tax liabilities of the respective foreign entity, management currently believes that the majority of these assets will not be realized and has, accordingly, established a $16.2 million valuation reserve. The $3.3 million increase from the prior year-end valuation reserve reflects the impact of changes in currency exchange rates, additional reserves established incident to purchase accounting for acquisitions, the expiration of operating loss carryforwards and changes in the anticipated realizability of certain foreign deferred tax assets.
     The Company has provided additional taxes for the anticipated repatriation of certain earnings of its non-U.S. subsidiaries. Undistributed earnings above the amounts upon which additional taxes have been provided, which approximated $291.1 million at December 31, 2006, are intended to be permanently invested by the Company. It is not practicable to determine the amount of applicable taxes that would be incurred if any of such earnings were repatriated.
     The American Jobs Creation Act of 2004 (the “Act”), which was enacted during the fourth quarter of 2004, created a temporary incentive for U.S. corporations to repatriate accumulated earnings of non-U.S. subsidiaries by providing an 85 percent deduction for certain dividends from controlled foreign corporations. During the fourth quarter of 2005, the Company completed its evaluation of the provisions of the new tax law and potential repatriations. Approximately $18.9 million of non-U.S. earnings were repatriated pursuant to the Act, resulting in the recognition of net tax benefits totaling $1.0 million in 2005.

Dividend Program
     In February 2005, the Company’s Board of Directors approved a regular quarterly cash dividend program. The Board of Directors declared dividends of $64.0 million, or $0.32 per share, and $48.4 million, or $0.24 per share, for the years ended December 31, 2006 and 2005, respectively.
     The level of future dividend payments will be at the discretion of the Board of Directors and will depend upon the Company’s financial condition, earnings and cash flow from operations, the level of its capital expenditures, compliance with certain debt covenants, its future business prospects and other factors that the Board of Directors deem relevant.

     On July 21, 2005, the Company’s Board of Directors approved a two-for-one stock split, which was effected in the form of a stock dividend. Stockholders of record as of August 5, 2005 were entitled to the dividend, which was distributed on August 24, 2005.
Common Stock Repurchases
     In October 2005, the Company’s Board of Directors approved a share repurchase program that allows for the purchase of up to 20 million shares of the Company’s common stock, subject to regulatory issues, market considerations and other relevant factors. The Company has purchased $102.9 million, $117.8 million and $92.0 million of common stock during 2006, 2005, and 2004, respectively, under the existing and a previously authorized repurchase program (collectively the “Repurchase Programs”). As of December 31, 2006, approximately 17.3 million shares remained available for purchase under the current program which may be executed from time to time in the open market. Common stock obtained by the Company through the Repurchase Programs has been added to the Company’s treasury stock holdings.
     In addition, certain participants in the long-term incentive plans surrender shares of common stock in order to satisfy tax withholding obligations. The Company acquired an immaterial number of shares in the prior three year period which have been added to the Company’s treasury stock holdings and may be used in the future for acquisitions or other corporate purposes. These shares are not considered acquisitions under the Company’s Repurchase Programs.
Stockholder Rights Plan
     On June 8, 2000, the Company adopted a Stockholder Rights Plan (the “Rights Plan”). As part of the Rights Plan, the Company’s Board of Directors declared a dividend of one junior participating preferred stock purchase right (“Right”) for each share of the Company’s common stock outstanding on June 20, 2000. The Board also authorized the issuance of one such Right for each share of the Company’s common stock issued after June 20, 2000 until the occurrence of certain events.
     The Rights are exercisable upon the occurrence of certain events related to a person (an “Acquiring Person’) acquiring or announcing the intention to acquire beneficial ownership of 20 percent or more of the Company’s common stock. In the event any person becomes an Acquiring Person, each holder (except an Acquiring Person) will be entitled to purchase, at an effective exercise price of $87.50, subject to adjustment, shares of common stock having a market value of twice the Right’s exercise price. The Acquiring Person will not be entitled to exercise these Rights. In addition, if at any time after a person has become an Acquiring Person, the Company is involved in a merger or other business combination transaction, or sells 50 percent or more of its assets or earning power to another entity, each Right will entitle its holder to purchase, at an effective exercise price of $87.50, subject to adjustment, shares of common stock of such other entity having a value of twice the Right’s exercise price. After a person or group becomes an Acquiring Person, but before an Acquiring Person owns 50% or more of the Company’s common stock, the Board may extinguish the Rights by exchanging one share of common stock, or an equivalent security, for each Right, other than Rights held by the Acquiring Person.
     In the event the Rights become exercisable and sufficient shares of the Company’s common stock are not authorized to permit the exercise of all outstanding Rights, the Company is required under the Rights Plan to take all necessary action including, if necessary, seeking stockholder approval to obtain additional authorized shares.
     The Rights are subject to redemption at the option of the Board of Directors at a price of one-quarter of a cent per Right until the occurrence of certain events. The Rights currently trade with Smith common stock, have no voting or dividend rights and expire on June 8, 2010.

13. Retirement Plans
Defined Contribution Plans
     The Company established the Smith International, Inc. 401(k) Retirement Plan (the “Smith Plan”) for the benefit of all eligible employees. Employees may voluntarily contribute a percentage of their compensation, as defined, to the Smith Plan. The Company makes basic, retirement and, in certain cases, discretionary matching contributions to each participant’s account under the Smith Plan. Participants receive a basic match on contributions to the Smith Plan of up to 11/2 percent of qualified compensation and a retirement contribution ranging from two percent to six percent of qualified compensation. In addition, the Board of Directors may provide discretionary profit-sharing contributions based upon financial performance to participants who are employed by the Company on December 31.
     Through September 30, 2004, eligible employees of Wilson International, Inc. (the “Wilson employees”) participated in the Smith Plan. Effective October 1, 2004, the Company established the Wilson 401(k) Retirement Plan (the “Wilson Plan”) and transferred account balances of the Wilson employees into this plan from the Smith Plan. Employees may voluntarily contribute a percentage of their compensation, as defined, to the Wilson Plan. Wilson makes matching contributions to each participant’s account ranging from 1/4 percent to six percent of qualified compensation. In addition, the Board of Directors may provide discretionary profit-sharing contributions based upon financial performance to participants who are employed by Wilson on December 31.
     M-I SWACO has a company Profit-Sharing and Savings Plan (the “M-I Retirement Plan”) under which participating employees may voluntarily contribute a percentage of their compensation, as defined. At its discretion, M-I SWACO may make basic, matching and in certain cases, discretionary matching contributions to each participant’s account under the M-I Retirement Plan. Participants are eligible to receive a basic contribution equal to three percent of qualified compensation, and a full match on employee contributions of up to 11/2 percent of qualified compensation. In addition, the Board of Directors may provide discretionary profit-sharing contributions based upon financial performance to participants who are employed by M-I SWACO on December 31.
     The Company recognized expense totaling $50.5 million, $37.8 million, and $34.0 million in 2006, 2005 and 2004, respectively, related to Company contributions to the plans.
     Certain of the Company’s subsidiaries sponsor various defined contribution plans. The Company’s contributions under these plans for each of the three years in the period ended December 31, 2006 were immaterial.
Deferred Compensation Plans
     The Company maintains Supplemental Executive Retirement Plans (“SERP”), non-qualified, deferred compensation programs, for the benefit of officers and certain other eligible employees of the Company. Participants may contribute up to 100 percent of cash compensation, on a pre-tax basis, as defined. Plan provisions allow for retirement and matching contributions, similar to those provided under the Company’s defined contribution programs, and, in certain cases, an interest contribution in order to provide a yield on short-term investments equal to 120 percent of the long-term applicable federal rate, as defined.
     In the event of insolvency or bankruptcy, plan assets are available to satisfy the claims of all general creditors of the Company. Accordingly, the accompanying consolidated balance sheets reflect the aggregate participant balances as both an asset and a liability of the Company. As of December 31, 2006 and 2005, $59.3 million and $50.7 million, respectively, are included in other assets with a corresponding amount recorded in other long-term liabilities.

14. Employee Benefit Plans
     The Company currently maintains various defined benefit pension plans covering certain U.S. and non-U.S. employees. Future benefit accruals and the addition of new participants under the U.S. plans were frozen prior to 1998.
     The Company and certain subsidiaries have postretirement benefit plans which provide health care benefits to a limited number of current, and in certain cases, future retirees. Individuals who elect to contribute premiums are eligible to participate in the Company’s medical and prescription drug programs, with certain limitations. In addition to premiums, the retiree is responsible for deductibles and any required co-payments and is subject to annual and lifetime dollar spending caps.

Additional Pension Plan Information
     In determining the expected return on plan assets, the Company considers the investment mix, the historical market performance and economic and other indicators of future performance. The Company primarily utilizes a mix of common stock and fixed income index funds to generate asset returns comparable with the general market. The investment mix of pension assets at December 31 is summarized in the following table:
                 
    2006   2005
Common stock and related index funds
    47 %     46 %
Fixed income securities and related index funds
    40       41

    6       6  
Money market funds
    7       7  
 
               
Total
    100 %     100 %
 
               
     For pension plans with accumulated benefit obligations in excess of plan assets, the following table sets forth the projected and accumulated benefit obligations and the fair value of plan assets at December 31:
                 
    2006   2005
Projected benefit obligation
  $ 49,988     $ 46,631  
Accumulated benefit obligation
    49,988       46,631  
Plan assets at fair value
    44,616       38,993  
     Estimated future benefit payments based on projected future service are expected to range between $1.0 million and $1.5 million a year for the next five years and approximate $12.6 million for the five-year period ending December 31, 2016. Company contributions to the pension plans during 2007 are expected to be comparable with 2006 contribution levels.
Additional Postretirement Benefit Plan Information
     The assumed health care cost trend rates used to determine the projected postretirement benefit obligation at December 31 are as follows:
                 
    2006   2005
Health care cost trend rate for current year
    12 %     10 %
Rate that the cost trend rate gradually declines (ultimate trend rate)
    5 %     5 %
Year that the rate reaches the ultimate trend rate
    2016       2010

     Estimated future benefit payments based on projected future service are expected to range between $0.5 million and $0.6 million a year for the next five years and approximately $3.3 million for the five-year period ending December 31, 2016. Company contributions to the postretirement benefit plans during 2007 are expected to be comparable to the 2006 levels.
15. Long-Term Incentive Compensation
     As of December 31, 2006, the Company had outstanding restricted stock and stock option awards granted under the 1989 Long-Term Incentive Compensation Plan (the “Plan”). As of December 31, 2006, 1,857,308 shares were authorized for future issuance pursuant to the Plan.
Restricted Stock Units
     The restricted stock program consists of a combination of performance-based restricted stock units (“performance-based units”) and time-based restricted stock units (“time-based units”). The number of performance-based units issued under the program, which can range from zero to 115 percent of the target units granted, is solely dependent upon the return on equity achieved by the Company in the fiscal year subsequent to the award. A summary of the Company’s restricted stock program is presented below:

(b)   Reflects achievement of performance criteria for awards granted prior to December 2006.
The total intrinsic value of restricted stock units vested during the years ended December 31, 2006, 2005, and 2004 was $12.5 million, $1.2 million, and $0.9 million, respectively. In addition, restrictions on approximately 710,138 performance-based units and 150,434 time-based units outstanding at December 31, 2006 are expected to lapse during the 2007 fiscal year.
Stock Options
     Stock options are generally granted at the fair market value on the date of grant, vest over a four-year period and expire ten years after the date of grant. A summary of the Company’s stock option program is presented below:

Table of Contents

     The Company used an open form (lattice) model to determine the fair value of options granted, and accordingly, calculate the share-based compensation expense. The fair value and assumptions used are as follows:
                         
    2006   2005   2004
Fair value of stock options granted
  $ 11.92     $ 8.53     $ 8.92  
Expected life of option (years)
    5.0       5.0       5.0  
Expected stock volatility
    31.0 %     31.0 %     31.0 %
Expected dividend yield
    0.8 %     0.8 %     N/A  
Risk-free interest rate
    4.3 %     3.9 %     3.6 %
     Expected volatilities are based on both historical volatility of the company’s stock price and implied volatility of exchange-traded options on the company’s stock. The expected life of options is based on historical data for options granted by the company after 1994. The risk-free rates are based on yields available at the time of grant on U.S. Treasury bonds for maturities consistent with the expected life assumption.
Share-based Compensation Expense
     Compensation expense for stock options and time-based units is recognized over the four-year vesting period. For performance-based units, compensation expense is recognized over the three-year vesting period.
     Prior to the adoption of SFAS No. 123r, compensation expense for the performance-based units was calculated as the difference between the market value and the exercise price. After adoption of SFAS No. 123r, compensation expense for the performance-based units and time-based units is based on the grant-date fair value. Share-based compensation expense, consisting of restricted stock unit and stock option awards, for the year ended December 31, 2006 was $27.3 million and, net of taxes and minority interests, was $17.5 million. For the years ended December 31, 2005 and 2004, compensation expense related to restricted stock unit awards totaled $5.7 million and $0.3 million, respectively.
     The total unrecognized share-based compensation expense, consisting of restricted stock and stock options, for awards outstanding as of December 31, 2006 was $74.2 million or approximately $44.6 million, net of taxes and minority interests, which will be recognized over a weighted-average period of 2.6 years.
16. Industry Segments and International Operations
     The Company provides premium products and services to the oil and gas exploration and production industry. The Company aggregates its operations into two reportable segments: Oilfield and Distribution. The Oilfield segment consists of three business units: M-I SWACO, which provides drilling and completion fluid systems and services, solids-control and separation equipment, waste-management services and oilfield production chemicals; Smith Technologies, which designs, manufactures and sells three-cone drill bits, diamond drill bits and turbine products; and Smith Services, which manufactures and markets products and services used for drilling, workover, well completion and well re-entry operations. The principal markets for the Oilfield segment include all major oil and gas-producing regions of the world, with approximately 55 percent of revenues generated in markets outside of North America. Oilfield segment customers primarily include major multi-national, independent and national, or state-owned, oil companies.
     The Distribution segment consists of one business unit, Wilson, which markets pipe, valves, fittings and mill, safety and other maintenance products to energy and industrial markets. The Distribution segment has the most significant North American exposure of any of the Company’s operations with approximately 96 percent of revenues derived in the United States and Canada. Approximately two-thirds of Wilson’s revenues are generated from customers in the energy sector, which includes major multi-national and independent oil companies, pipeline companies and contract drilling companies. The remainder relates to sales in the downstream and industrial markets, which primarily includes refineries, petrochemical and power generation plants.
     The Company’s revenues are derived principally from uncollateralized customer sales. The significant energy industry concentration has the potential to impact the Company’s exposure to credit risk, either positively or negatively, because customers may be similarly affected by changes in economic or other conditions. The creditworthiness of the Company’s customer base is strong, with limited credit losses experienced on such receivables.

17. Commitments and Contingencies
Leases
     The Company routinely enters into operating and capital leases for certain of its facilities and equipment. Amounts related to assets under capital lease were immaterial for the periods presented. Rent expense totaled $127.1 million, $102.1 million, and $94.8 million in 2006, 2005, and 2004, respectively.
     Future minimum payments under non-cancelable operating leases having initial terms of one year or more are as follows:
         
    Amount  
2007
  $ 54,524  
2008
    40,798  
2009
    27,598  
2010
    20,757  
2011
    11,421  
2012-2016
    23,309  
Thereafter
    13,455  
 
     
 
  $ 191,862  
 
     
     In the normal course of business, the Company enters into lease agreements with cancellation provisions as well as agreements with initial terms of less than one year. The costs related to these leases have been reflected in rent expense but have been appropriately excluded from the future minimum payments presented above.
Standby Letters of Credit
     In the normal course of business with customers, vendors and others, the Company is contingently liable for performance under standby letters of credit and bid, performance and surety bonds. Certain of these outstanding instruments guarantee payment to insurance companies which reinsure certain liability coverages of the Company’s insurance captive. Excluding the impact of these instruments, for which $19.4 million of related liabilities are reflected in the accompanying consolidated balance sheet, the Company was contingently liable for approximately $78.3 million of standby letters of credit and bid, performance and surety bonds at December 31, 2006. Management does not expect any material amounts to be drawn on these instruments.
Insurance
     The Company maintains insurance coverage for various aspects of its business and operations. The Company has elected to retain a portion of losses that occur through the use of deductibles and retentions under its insurance programs. 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 management believes that amounts accrued in the accompanying consolidated financial statements are adequate for expected liabilities arising from the Company’s portion of losses, estimates of these liabilities may change as circumstances develop.
Litigation
Rose Dove Egle v. John M. Egle, et al.
     In April 1997, the Company acquired all of the equity interests in Tri-Tech Fishing Services, L.L.C. (“Tri-Tech”) in exchange for cash consideration of approximately $20.4 million (the “Transaction”).
     In August 1998, the Company was added as a defendant in a First Amended Petition filed in the 15th Judicial District Court, Parish of Lafayette, Louisiana entitled Rose Dove Egle v. John M. Egle, et al. In the amended petition, the plaintiffs alleged that, due to an improper conveyance of ownership interest by the Tri-Tech majority partner prior to the Transaction, Smith purchased a portion of its equity interest from individuals who were not legally entitled to their Tri-Tech shares. The suit was tried in the first quarter of 2004, and a jury verdict of approximately $4.8 million was rendered in favor of the plaintiffs. The Company has appealed the verdict and does not anticipate a ruling until the third quarter of 2007. Based upon the facts and circumstances and the opinion of outside legal counsel, management believes that an unfavorable outcome on this matter is not probable at this time. Accordingly, the Company has not recognized a loss provision in the accompanying consolidated financial statements.

Other
     The Company is a defendant in various other legal proceedings arising in the ordinary course of business. In the opinion of management, these matters will not have a material adverse effect on the Company’s consolidated financial position or results of operations.
Environmental
     The Company routinely establishes and reviews the adequacy of reserves for estimated future environmental clean-up costs for properties currently or previously operated by the Company.
     As of December 31, 2006, the Company’s environmental reserve totaled $8.4 million. This amount reflects the future undiscounted estimated exposure related to identified properties, without regard to indemnifications from former owners. While actual future environmental costs may differ from estimated liabilities recorded at December 31, 2006, the Company does not believe that these differences will have a material impact on the Company’s financial position or results of operations.
