General

The Company’s products are used by pharmaceutical, life science, biochemical, industrial, academic and government customers working in research and development, quality assurance and other laboratory applications. The Company’s LC and MS instruments are utilized in this broad range of industries to detect, identify, monitor and measure the chemical, physical and biological composition of materials, as well as to purify a full range of compounds. These instruments are used in drug discovery and development, including clinical trial testing, the analysis of proteins in disease processes (known as “proteomics”), food safety analysis and environmental testing. The Company’s thermal analysis, rheometry and calorimetry instruments are used in predicting the suitability of fine chemicals, polymers and viscous liquids for uses in various industrial, consumer goods and healthcare products, as well as for life science research.

Waters is a holding company that owns all of the outstanding common stock of Waters Technologies Corporation, its operating subsidiary. Waters became a publicly traded company with its initial public offering (“IPO”) in November 1995. Since the IPO, the Company has added two significant and complementary technologies to its range of products with the acquisitions of TA Instruments in May 1996 and Micromass Limited (“Micromass^®”) in September 1997.

Business Segments

The Company’s business activities, for which financial information is available, are regularly reviewed and evaluated by the chief operating decision makers. As a result of this evaluation, the Company determined that it has two operating segments: Waters Division and TA Division. As indicated above, the Company operates in the analytical instruments industry, designing, manufacturing, distributing and servicing products in three technologies: LC and MS instruments; columns and other consumables; and thermal analysis, rheometry and calorimetry instruments. The Company’s two operating segments, Waters Division and TA Division, have similar economic characteristics; product processes; products and services; types and classes of customers; methods of distribution and regulatory environments. Because of these similarities, the two segments have been aggregated into one reporting segment for financial statement purposes.

Information concerning revenues and long-lived assets attributable to each of the Company’s products, services and geographic areas is set forth in Note 16 in the Notes to the Consolidated Financial Statements, which is incorporated herein by reference.

Waters Division

High Performance and Ultra Performance Liquid Chromatography

Developed in the 1950’s, HPLC is the standard technique used to identify and analyze the constituent components of a variety of chemicals and other materials. The Company believes that HPLC’s performance capabilities enable it to separate and identify approximately 80% of all known chemicals and materials. As a result, HPLC is used to analyze substances in a wide variety of industries for research and development purposes, quality control and process engineering applications.

The most significant end-use markets for HPLC are those served by the pharmaceutical and life science industries. In these markets, HPLC is used extensively to identify new drugs, develop manufacturing methods and assure the potency and purity of new pharmaceuticals. HPLC is also used in a variety of other applications, such as analyses of foods and beverages for nutritional labeling and compliance with safety regulations, the testing of water and air purity within the environmental testing industry, as well as applications in other industries, such as chemical and consumer products. HPLC is also used by universities, research institutions and government agencies, such as the United States Food and Drug Administration (“FDA”) and the United States Environmental Protection Agency (“EPA”) and their international counterparts who mandate testing requiring HPLC instrumentation.

Traditionally, a typical HPLC system has consisted of five basic components: solvent delivery system, sample injector, separation column, detector and data acquisition unit. The solvent delivery system pumps solvents through the HPLC system, while the sample injector introduces samples into the solvent flow. The chromatography column then separates the sample into its components for analysis by the detector, which measures the presence and amount of the constituents. The data acquisition unit, usually referred to as the instrument’s software or data system, then records and stores the information from the detector.

In 2004, Waters introduced a novel technology that the Company describes as ultra performance liquid chromatography that utilizes a packing material with small, uniform diameter particles and a specialized instrument, the ACQUITY UPLC^®, to accommodate the increased pressure and narrow chromatographic bands that are generated by these small particles. By using the ACQUITY UPLC, researchers and analysts are able to achieve more comprehensive chemical separations and faster analysis times in comparison with many analyses performed by HPLC. In addition, in using ACQUITY UPLC, researchers have the potential to extend the range of applications beyond that of HPLC, enabling them to uncover new levels of scientific information. Though it offers significant performance advantages, ACQUITY UPLC is compatible with the Company’s software products and the general operating protocols of HPLC. For these reasons, the Company’s customers and field sales and support organizations are well positioned to utilize this new technology and instrument. The Company began shipping the ACQUITY UPLC in the third quarter of 2004. During 2009, 2008 and 2007, the Company experienced growth in the LC instrument system product line primarily from the sales of ACQUITY UPLC systems.

Waters manufactures LC instruments that are offered in configurations that allow for varying degrees of automation, from component configured systems for academic research applications to fully automated systems for regulated testing, and that have a variety of detection technologies, from ultra-violet (“UV”) absorbance to MS, optimized for certain analyses. The Company also manufactures tailored LC systems for the analysis of biologics, as well as an LC detector utilizing evaporative light scattering technology to expand the usage of LC to compounds that are not amenable to UV absorbance detection.

The primary consumable products for LC are chromatography columns. These columns are packed with separation media used in the LC testing process and are replaced at regular intervals. The chromatography column contains one of several types of packing material, typically stationary phase particles made from silica. As the sample flows through the column, it is separated into its constituent components.

Waters HPLC columns can be used on Waters-branded and competitors’ LC systems. The Company believes that it is one of the few suppliers in the world that processes silica, packs columns and distributes its own products. In doing so, the Company believes it can better ensure product consistency, a key attribute for its customers in quality control laboratories, and react quickly to new customer requirements. The Company believes that its ACQUITY UPLC lines of columns are used nearly exclusively on its ACQUITY UPLC instrument and, furthermore, that its ACQUITY UPLC instrument primarily uses ACQUITY UPLC columns. In 2009, 2008 and 2007, excluding the small impact from acquisitions mentioned below, the Company experienced growth in its LC chromatography column and sample preparation businesses, especially in ACQUITY UPLC columns.

In February 2009, the Company acquired all of the remaining outstanding capital stock of Thar Instruments, Inc. (“Thar”), a privately-held global leader in the design, development and manufacture of analytical and preparative supercritical fluid chromatography and supercritical fluid extraction (“SFC”) systems, for $36 million in cash, including the assumption of $4 million of debt. In December 2008, the Company acquired the net assets of Analytical Products Group, Inc. (“APG”), a provider of environmental testing products for quality control and proficiency testing used in environmental laboratories, for $5 million in cash. The APG business has been integrated

into the Company’s Environmental Resources Associates, Inc. (“ERA”) business, which was acquired in December 2006. The Company acquired all of the outstanding capital stock of ERA, a provider of environmental testing products for quality control, proficiency testing and specialty calibration chemicals used in environmental laboratories, for $62 million in cash, including the assumption of $4 million of debt. ERA also provides product support services required to help laboratories with their federal and state mandated accreditation requirements or with quality control over critical pharmaceutical analysis. In February 2006, the Company acquired the net assets of the food safety business of VICAM^® Limited Partnership (“VICAM”) for $14 million in cash. VICAM is a leading provider of tests to identify and quantify mycotoxins in various agricultural commodities. The Company’s test kits provide reliable, quantitative detection of particular mycotoxins through the choice of flurometer, LC-MS or HPLC. The APG, ERA and VICAM acquisitions are part of the chemistry consumable product line.

Based upon reports from independent marketing research firms and publicly disclosed sales figures from competitors, the Company believes that it is one of the world’s largest manufacturers and distributors of LC instruments, chromatography columns and other consumables and related services. The Company also believes that it has the leading LC market share in the United States, Europe and Asia, and believes it has a leading market share position in Japan.

Mass Spectrometry

Mass spectrometry is a powerful analytical technique that is used to identify unknown compounds, to quantify known materials and to elucidate the structural and chemical properties of molecules by measuring the masses of individual molecules that have been converted into ions.

The Company believes it is a market leader in the development, manufacture, sale and distribution of MS instruments. These instruments can be integrated and used along with other complementary analytical instruments and systems, such as LC, chemical electrophoresis, chemical electrophoresis chromatography and gas chromatography. A wide variety of instrumental designs fall within the overall category of MS instrumentation, including devices that incorporate quadrupole, ion trap, time-of-flight (“Tof”) and classical magnetic sector technologies. Furthermore, these technologies are often used in tandem to maximize the efficacy of certain experiments.

Currently, the Company offers a wide range of MS instruments utilizing various combinations of quadrupole, Tof, ion mobility and magnetic sector designs. These instruments are used in drug discovery and development, as well as for environmental and food safety testing. The majority of mass spectrometers sold by the Company are designed to utilize an LC system as the sample introduction device. These products supply a diverse market with a strong emphasis on the life science, pharmaceutical, biomedical, clinical, food and environmental market segments worldwide.

The mass spectrometer is an increasingly important detection device for LC. The Company’s smaller-sized mass spectrometers (such as the SQD and the TQD) are often referred to as LC “detectors” and are either sold as part of an LC system or as an LC system upgrade. Larger quadrupole systems, such as the Xevo^tm TQ and Quattro Premier^tm XE instruments, are used primarily for experiments performed for late-stage drug development, including clinical trial testing, and quadrupole time-of-flight (“Q-Tof^tm”) instruments, such as the Company’s Synapt^tm MS, are often used to analyze the role of proteins in disease processes, an application sometimes referred to as “proteomics”. In 2006, the Company introduced the tandem quadrupole device, the TQD, and a new hybrid Q-Tof technology system, the Synapt^tm HDMS^tm. The Synapt HDMS system integrates ion mobility technology within a Q-Tof geometry instrument configuration and uniquely allows researchers to glean molecular shape information, a novel capability for a mass spectrometry instrument. In 2008, the Company introduced a new Q-Tof instrument called the Synapt MS. This instrument is an improved version of the Q-Tof Premier^tm that customers may opt to upgrade to Synapt HDMS capability. In late 2008, the Xevo^tm QTof^tm MS, an exact mass MS/MS bench-top instrument, was introduced. In late 2009, the Company introduced the Synapt^tm G2 HDMS^tm system. The Synapt G2 HDMS and Synapt^tm G2 MS systems are high resolution exact mass MS/MS platforms that are performance enhanced replacements for the Synapt HDMS and Synapt MS systems. The performance enhancements offered by these new systems allow for higher resolution shape discrimination by the HDMS version and superior mass resolution, mass accuracy and quantification accuracy by both versions.

LC-MS

LC and MS are instrumental technologies often embodied within an analytical system tailored for either a dedicated class of analyses or as a general purpose analytical device. An increasing percentage of the Company’s customers are purchasing LC and MS components simultaneously and it is becoming common for LC and MS instrumentation to be used within the same laboratory and operated by the same user. The descriptions of LC and MS above reflect the historical segmentation of these analytical technologies and the historical categorization of their respective practitioners. Increasingly in today’s instrument market, this segmentation and categorization is becoming obsolete as a high percentage of instruments used in the laboratory embody both LC and MS technologies as part of a single device. In response to this development and to further promote the high utilization of these hybrid instruments, the Company has organized its Waters Division to develop, manufacture, sell and service integrated LC-MS systems.

Waters Division Service

The servicing and support of LC and MS instruments and accessories is an important source of revenue for the Waters Division. These revenues are derived primarily through the sale of support plans, demand service, customer training and performance validation services. Support plans most typically involve scheduled instrument maintenance and an agreement to promptly repair a non-functioning instrument in return for a fee described in a contract that is priced according to the configuration of the instrument.

TA Division

Thermal Analysis, Rheometry and Calorimetry

Thermal analysis measures the physical characteristics of materials as a function of temperature. Changes in temperature affect several characteristics of materials, such as their physical state, weight, dimension and mechanical and electrical properties, which may be measured by one or more thermal analysis techniques, including calorimetry. Consequently, thermal analysis techniques are widely used in the development, production and characterization of materials in various industries, such as plastics, chemicals, automobiles, pharmaceuticals and electronics.

Rheometry instruments complement thermal analyzers in characterizing materials. Rheometry characterizes the flow properties of materials and measures their viscosity, elasticity and deformation under different types of “loading” or conditions. The information obtained under such conditions provides insight into a material’s behavior during manufacturing, transport, usage and storage.

Thermal analysis and rheometry instruments are heavily used in material testing laboratories and, in many cases, provide information useful in predicting the suitability of fine chemicals, polymers and viscous liquids for various industrial, consumer goods and healthcare products, as well as for life science research. As with systems offered through the Waters Division, a range of instrumental configurations are available with increasing levels of sample handling and information processing automation. In addition, systems and accompanying software packages can be tailored for specific applications. For example, the Q-Series^tm family of differential scanning calorimeters includes a range of instruments, from basic dedicated analyzers to more expensive systems that can accommodate robotic sample handlers and a variety of sample cells and temperature control features for analyzing a broad range of materials. In 2009, TA introduced the ARIES G2 rheometer, a high performance system uniquely capable of independently measuring stress and strain for a wide variety of solids and liquids.

In July 2008, the Company acquired the net assets of VTI Corporation (“VTI”), a manufacturer of sorption analysis and thermogravimetric analysis instruments, for $3 million in cash. VTI’s products are widely used in the evaluation of pharmaceuticals, catalysts and energy-related materials. This acquisition added two technologies which complement TA’s existing gravimetric analysis product line. VTI’s sorption analysis products are designed for water and organic vapor sorption studies of pharmaceuticals and related materials. VTI’s high pressure, high vacuum TGA projects are designed for high pressure sorption studies, which are commonly used in the analysis of energy-related materials.

calorimeters, for $7 million in cash, including the assumption of $1 million of liabilities. CSC products and services are primarily used in the life sciences industry. This acquisition added two systems which complement TA’s existing TAM micro-calorimeter product line. The Nano-ITC is an isothermal titration calorimeter designed to measure protein-ligand binding and the interaction of biological materials. The Nano-DSC is an ultra-sensitive scanning calorimeter used to measure the stability of proteins and other macromolecules in dilute solutions and is commonly used in pharmaceutical development processes.

In August 2006, the Company acquired all of the outstanding capital stock of Thermometric AB (“Thermometric”), a manufacturer of high performance micro-calorimeters, for $3 million in cash, including the assumption of $1 million of debt. Thermometric’s flagship product, the TAM III, is a modular calorimeter that employs proprietary technology to deliver calorimetric sensitivity and temperature stability. It is used to characterize materials and their interactions in the fields of pharmaceuticals, life and materials sciences. The TAM III systems complement TA’s industry leading Q-Series differential scanning calorimeter product line and the CSC product lines acquired in 2007. Thermometric’s manufacturing and research and development were moved and consolidated with CSC late in 2008.

TA Service

The Company sells, supports and services TA Division’s product offerings through its headquarters in New Castle, Delaware. TA operates independently from the Waters Division, though several of its overseas offices are situated in Waters’ facilities. TA has dedicated field sales and service operations. Service sales are primarily derived from the sale of replacement parts and from billed labor fees associated with the repair, maintenance and upgrade of installed systems.

Customers

The Company has a broad and diversified customer base that includes pharmaceutical accounts, other industrial accounts, universities and government agencies. The pharmaceutical segment represents the Company’s largest sector and includes multinational pharmaceutical companies, generic drug manufacturers, contract research organizations (CROs) and biotechnology companies. The Company’s other industrial customers include chemical manufacturers, polymer manufacturers, food and beverage companies and environmental testing laboratories. The Company also sells to various universities and government agencies worldwide. The Company’s technical support staff works closely with its customers in developing and implementing applications that meet their full range of analytical requirements.

The Company does not rely on any single customer or one group of customers for a material portion of its sales. During fiscal years 2009, 2008 and 2007, no single customer accounted for more than 3% of the Company’s net sales.

Sales and Service

The Company has one of the largest sales and service organizations in the industry, focused exclusively on the various instrument systems’ installed base. Across these product technologies, using respective specialized sales and service forces, the Company serves its customer base with approximately 2,700 field representatives in 92 sales offices throughout the world as of December 31, 2009. The Company’s sales representatives have direct responsibility for account relationships, while service representatives work in the field to install instruments, train and minimize instrument downtime for customers. In-house, technical support representatives work directly with customers providing them assistance with applications and procedures on Company products. The Company provides customers with comprehensive information through various corporate and regional internet websites and product literature, and also makes consumable products available through electronic ordering facilities and a dedicated catalog.

Manufacturing

The Company provides high quality LC products by overseeing each stage of the production of its instruments, columns and chemical reagents. The Company currently assembles a portion of its LC instruments at its facility in

Milford, Massachusetts, where it performs machining, assembly and testing. The Milford facility maintains a quality management system in accordance with the requirements of ISO 9001:2000, ISO 13485:2003, ISO 14001:2004 and applicable regulatory requirements (including FDA Quality System Regulations and the European In-Vitro Diagnostics Directives). The Company outsources manufacturing of certain electronic components, such as computers, monitors and circuit boards, to outside vendors that can meet the Company’s quality requirements. In 2006, the Company transitioned the manufacturing of LC instrument systems and components to a well-established contract manufacturing firm in Singapore. The Company expects to continue pursuing outsourcing opportunities.

The Company manufactures its LC columns at its facilities in Taunton, Massachusetts and Wexford, Ireland, where it processes, sizes and treats silica and polymeric media that are packed into columns, solid phase extraction cartridges and bulk shipping containers. The Wexford facility also manufactures and distributes certain data, instruments and software components for the Company’s LC, MS and TA Division product lines. These facilities meet similar ISO and FDA standards met by the Milford, Massachusetts facility and are registered with the FDA. VICAM manufactures antibody resin and magnetic beads that are packed into columns and kits in Milford, Massachusetts and Nixa, Missouri. ERA manufactures environmental proficiency kits in Arvada, Colorado. Thar manufactures SFC systems in Pittsburgh, Pennsylvania.

The Company manufactures most of its MS products at its facilities in Manchester, England, Cheshire, England and Wexford, Ireland. Certain components or modules of the Company’s MS instruments are manufactured by long-standing outside contractors. Each stage of this supply chain is closely monitored by the Company to maintain high quality and performance standards. The instruments, components or modules are then returned to the Company’s facilities where its engineers perform final assembly, calibrations to customer specifications and quality control procedures. The Company’s MS facilities meet similar ISO and FDA standards met by the Milford, Massachusetts facility and are registered with the FDA.

Thermal analysis, rheometry and calorimetry products are manufactured by TA. Thermal analysis products are manufactured at the Company’s New Castle, Delaware facility. Rheometry products are manufactured at the Company’s New Castle, Delaware and Crawley, England facilities. Microcalorimetry products are manufactured at the Company’s Lindon, Utah facility. VTI manufactures sorption analysis and thermogravimetric analysis instruments in Hialeah, Florida. Similar to MS, elements of TA’s products are manufactured by outside contractors and are then returned to the Company’s facilities for final assembly, calibration and quality control. The Company’s thermal analysis facilities are certified to ISO 9001:2000 standards.

Research and Development

The Company maintains an active research and development program focused on the development and commercialization of products that both complement and update the existing product offering. The Company’s research and development expenditures for 2009, 2008 and 2007 were $77 million, $82 million and $81 million, respectively. Nearly all of the current LC products of the Company have been developed at the Company’s main research and development center located in Milford, Massachusetts, with input and feedback from the Company’s extensive field organizations and customers. The majority of the MS products have been developed at facilities in England and nearly all of the current thermal analysis products have been developed at the Company’s research and development center in New Castle, Delaware. At December 31, 2009, there were 677 employees involved in the Company’s research and development efforts. The Company has increased research and development expenses relating to acquisitions and the Company’s continued commitment to invest significantly in new product development and existing product enhancements. Despite the Company’s active research and development programs, there can be no assurances that the Company’s product development and commercialization efforts will be successful or that the products developed by the Company will be accepted by the marketplace.

Employees

The Company employed approximately 5,200 employees at December 31, 2009, with approximately 44% of the Company’s employees located in the United States. The Company believes its employee relations are generally good. The Company’s employees are not unionized or affiliated with any internal or external labor organizations.

The Company believes that its future success largely depends upon its continued ability to attract and retain highly skilled employees.

Competition

The analytical instrument and systems market is highly competitive. The Company encounters competition from several worldwide instrument manufacturers and other companies in both domestic and foreign markets for each of its three technologies. The Company competes in its markets primarily on the basis of instrument performance, reliability, service and, to a lesser extent, price. Some competitors have instrument businesses that are generally more diversified than the Company’s business, but are typically less focused on the Company’s chosen markets. Some competitors have greater financial and other resources than the Company.

In the markets served by the Waters Division, the Company’s principal competitors include: Agilent Technologies, Inc., Life Technologies Corporation, Thermo Fisher Scientific Inc., Varian, Inc., Shimadzu Corporation, Dionex Corporation and Bruker BioSciences. In 2009, Danaher Corporation announced an intention to acquire the mass spectrometry assets of Life Technologies Corporation and Agilent Technologies, Inc. announced plans to acquire Varian, Inc. In the markets served by the TA Division, the Company’s principal competitors include: PerkinElmer, Inc., Mettler-Toledo International Inc., NETZSCH-Geraetebau GmbH, Thermo Fisher Scientific Inc., Malvern Instruments Ltd., Anton-Paar and General Electric Company.

The market for consumable LC products, including separation columns, is highly competitive and more fragmented than the analytical instruments market. The Company encounters competition in the consumable columns market from chemical companies that produce column chemicals and small specialized companies that pack and distribute columns. The Company believes that it is one of the few suppliers that process silica, packs columns and distributes its own product. The Company competes in this market on the basis of reproducibility, reputation, performance and, to a lesser extent, price. The Company’s principal competitors for consumable products include: Phenomenex, Inc., Supelco, Inc., Agilent Technologies, Inc., General Electric Company, Thermo Fisher Scientific Inc. and Merck and Co., Inc. The ACQUITY UPLC instrument is designed to offer a predictable level of performance when used with ACQUITY UPLC columns and the Company believes that the expansion of the ACQUITY UPLC instrument base will enhance its chromatographic column business because of the high level of synergy between ACQUITY UPLC columns and the ACQUITY UPLC instrument. In 2009, Agilent Technologies, Inc. introduced a new LC system, which they termed a UHPLC, which they have claimed has similar performance characteristics to Waters’ ACQUITY UPLC.

Patents, Trademarks and Licenses

The Company owns a number of United States and foreign patents and has patent applications pending in the United States and abroad. Certain technology and software is licensed from third parties. The Company also owns a number of trademarks. The Company’s patents, trademarks and licenses are viewed as valuable assets to its operations. However, the Company believes that no one patent or group of patents, trademark or license is, in and of itself, essential to the Company such that its loss would materially affect the Company’s business as a whole.

Environmental Matters and Climate Change

The Company is subject to federal, state and local laws, regulations and ordinances that (i) govern activities or operations that may have adverse environmental effects, such as discharges to air and water as well as handling and disposal practices for solid and hazardous wastes, and (ii) impose liability for the costs of cleaning up and certain damages resulting from sites of past spills, disposals or other releases of hazardous substances. The Company believes that it currently conducts its operations and has operated its business in the past in substantial compliance with applicable environmental laws. From time to time, operations of the Company have resulted or may result in noncompliance with environmental laws or liability for cleanup pursuant to environmental laws. The Company does not currently anticipate any material adverse effect on its operations, financial condition or competitive position as a result of its efforts to comply with environmental laws.

The Company is sensitive to the growing global debate with respect to climate change. In the first quarter of 2009, the Company published its first sustainability report identifying the various actions and behaviors the

Company has adopted concerning its commitment to both the environment and the broader topic of social responsibility. An internal sustainability working group was formed and is functioning to develop increasingly robust data with respect to the Company’s utilization of carbon producing substances. See Item 1A, Risk Factors — Effects of Climate Change, for more information on the potential significance of climate change legislation.

Global Economic Conditions

The global economic conditions had an unfavorable impact on demand for the Company’s products in 2009 and in late 2008. These conditions resulted in a decline in demand for the Company’s products and services and may result in a decline in demand for the Company’s products and services in the near future. There can be no assurance that there will not be a further deterioration in financial markets and confidence in major economies. Any further deterioration or prolonged disruption in the financial markets or market conditions generally may result in reduced demand for the Company’s products and services. The Company’s global business may also be adversely affected by decreases in the general level of economic activity as a result of the economic and financial market situations.

Financial Market Conditions

Financial markets in the U.S., Europe and Asia have experienced extreme disruption over the past few years, including, among other things, a sharp increase in the cost of new capital, severely diminished capital availability and severely reduced liquidity in money markets. Financial and banking institutions have also experienced disruptions, resulting in large asset write-downs, higher costs of capital, rating downgrades and reduced desire to lend money. While currently these conditions have not impacted the Company’s ability to access its existing cash or borrow on its existing revolving credit facility, there can be no assurance that there will not be further deterioration or prolonged disruption in financial markets or financial institutions. Any further deterioration or prolonged disruption in financial markets or financial institutions in which the Company participates may impair the Company’s ability to access its existing cash and revolving credit facility and impair its ability to access sources of new capital. The Company’s cost of any new capital raised and interest expense would increase if this were to occur.

Customer Demand

The demand for the Company’s products is dependent upon the size of the markets for its LC, MS, thermal analysis, rheometry and calorimetry products; the timing and level of capital expenditures of the Company’s customers; changes in government regulations, particularly effecting drug, food and drinking water testing; funding available to academic and government institutions; general economic conditions and the rate of economic growth in the Company’s major markets; and competitive considerations. The Company typically experiences an increase in sales in its fourth quarter, as a result of purchasing habits for capital goods by customers that tend to exhaust their spending budgets by calendar year end. There can be no assurances that the Company’s results of operations or financial condition will not be adversely impacted by a change in any of the factors listed above or the continuation of weakness in global economic conditions.

Additionally, the analytical instrument market may, from time to time, experience low sales growth. Approximately 51% and 50% of the Company’s net sales in 2009 and 2008, respectively, were to the worldwide pharmaceutical and biotechnology industries, which may be periodically subject to unfavorable market conditions and consolidations. Unfavorable industry conditions could have a material adverse effect on the Company’s results of operations or financial condition.

Competition and the Analytical Instrument Market

The analytical instrument market and, in particular, the portion related to the Company’s HPLC, UPLC, MS, LC-MS, thermal analysis, rheometry and calorimetry product lines, is highly competitive and subject to rapid changes in technology. The Company encounters competition from several international instrument manufacturers and other companies in both domestic and foreign markets. Some competitors have instrument businesses that are generally more diversified than the Company’s business, but are typically less focused on the Company’s chosen markets. There can be no assurances that the Company’s competitors will not introduce more effective and less costly products than those of the Company or that the Company will be able to increase its sales and profitability from new product introductions. There can be no assurances that the Company’s sales and marketing forces will compete successfully against its competitors in the future.

Levels of Debt and Debt Service Requirements

The Company had approximately $632 million in debt and $630 million in cash, cash equivalents and short-term investments as of December 31, 2009. As of December 31, 2009, the Company also had the ability to borrow an additional $479 million from its existing credit facilities. Most of the Company’s debt is in the U.S. There is a substantial cash requirement in the U.S. to fund operations and capital expenditures, service debt interest obligations, finance potential acquisitions and continue authorized stock repurchase programs. A majority of the Company’s cash is maintained and generated from foreign operations. The Company’s financial condition and results of operations could be adversely impacted if the Company is unable to maintain a sufficient level of cash flow in the U.S. to address these requirements through cash from U.S. operations, efficient and timely repatriation of cash from overseas, the Company’s ability to access its existing cash and revolving credit facility and other sources obtained at an acceptable cost.

Debt Covenants

The Company’s debt may become subject to restrictive covenants that limit the Company’s ability to engage in certain activities that could otherwise benefit the Company. These debt covenants include restrictions on the Company’s ability to enter into certain contracts or agreements that may limit the Company’s ability to make dividend or other payments; secure other indebtedness; enter into transactions with affiliates and consolidate, merge or transfer all or substantially all of the Company’s assets. The Company is also required to meet specified financial ratios under the terms of the Company’s debt agreements. The Company’s ability to comply with these financial restrictions and covenants is dependent on the Company’s future performance, which is subject to, but not limited to, prevailing economic conditions and other factors, including factors that are beyond the Company’s control, such as foreign exchange rates, interest rates, changes in technology and changes in the level of competition.

Risk of Disruption of Operations

The Company manufactures LC instruments at facilities in Milford, Massachusetts and Singapore; chemistry separation columns at its facilities in Taunton, Massachusetts and Wexford, Ireland; MS products at its facilities in Manchester, England, Cheshire, England and Wexford, Ireland; thermal analysis products at its facility in New Castle, Delaware; rheometry products at its facilities in New Castle, Delaware and Crawley, England and other instruments and consumables at various other locations as a result of the Company’s recent acquisitions. Any prolonged disruption to the operations at any of these facilities, whether due to labor difficulties, destruction of or damage to any facility or other reasons, could have a material adverse effect on the Company’s results of operations or financial condition.

Sovereign Risk, Foreign Operations and Exchange Rates

Approximately 69% and 70% of the Company’s net sales in 2009 and 2008, respectively, were outside of the United States and were primarily denominated in foreign currencies. In addition, the Company has considerable manufacturing operations in Ireland, the United Kingdom and Singapore. As a result, a significant portion of the Company’s sales and operations are subject to certain risks, including adverse developments in the foreign political and economic environment; sudden movements in a country’s foreign exchange rates due to a change in a country’s sovereign risk profile or foreign exchange regulatory practices; tariffs and other trade barriers; difficulties in staffing and managing foreign operations; and potentially adverse tax consequences.

Additionally, the U.S. dollar value of the Company’s net sales, cost of sales, operating expenses, interest, taxes and net income varies with currency exchange rate fluctuations. Significant increases or decreases in the value of the U.S. dollar relative to certain foreign currencies could have a material adverse effect or benefit on the Company’s results of operations or financial condition.

Reliance on Key Management

The operation of the Company requires managerial and operational expertise. None of the key management employees have an employment contract with the Company and there can be no assurance that such individuals will remain with the Company. If, for any reason, such key personnel do not continue to be active in management, the Company’s results of operations or financial condition could be adversely affected.

Protection of Intellectual Property

The Company vigorously protects its intellectual property rights and seeks patent coverage on all developments that it regards as material and patentable. However, there can be no assurances that any patents held by the Company will not be challenged, invalidated or circumvented or that the rights granted thereunder will provide competitive advantages to the Company. Conversely, there could be successful claims against the Company by third-party patent holders with respect to certain Company products that may infringe the intellectual property rights of such third parties. The Company’s patents, including those licensed from others, expire on various dates. If the Company is unable to protect its intellectual property rights, it could have an adverse and material effect on the Company’s results of operations or financial condition.

Reliance on Suppliers

Most of the raw materials, components and supplies purchased by the Company are available from a number of different suppliers; however, a number of items are purchased from limited or single sources of supply and disruption of these sources could have a temporary adverse effect on shipments and the financial results of the Company. The Company believes alternative sources could ordinarily be obtained to supply these materials, but a prolonged inability to obtain certain materials or components could have an adverse effect on the Company’s financial condition or results of operations and could result in damage to its relationships with its customers and, accordingly, adversely affect the Company’s business.

Use of Outside Manufacturers

Certain components or modules of the Company’s LC and MS instruments are manufactured by long-standing outside contractors. Since 2006, the Company has transitioned the manufacturing of LC instrument systems and related components to a well-established contract manufacturing firm in Singapore. Disruptions of service by these outside contractors could have an adverse effect on the supply chain and the financial results of the Company. The Company believes that it could obtain alternative sources for these components or modules, but a prolonged inability to obtain these components or modules could have an adverse effect on the Company’s financial condition or results of operations.

Risk in Unexpected Shifts in Taxable Income between Tax Jurisdictions

The Company is subject to a range of income tax rates, from 0% to in excess of 35%, depending on specific tax jurisdictions around the world. The Company typically generates a substantial portion of its taxable income in the fourth quarter of each fiscal year. Shifts in actual taxable income from previous quarters’ projections due to factors, including, but not limited to, changes in volume and foreign currency translation rates, could have a notable favorable or unfavorable effect on the Company’s income tax expense and results of operations.

Effects of Climate Change

The Company’s manufacturing processes for certain of its products involve the use of chemical and other substances that are regulated under various international, federal, state and local laws governing the environment. In the event that any future climate change legislation would require that stricter standards be imposed by domestic or international environmental regulatory authorities with respect to the use and/or levels of possible emissions from such chemicals and/or other substances, the Company may be required to make certain changes and adaptations to

its manufacturing processes. There can be no assurance that any such changes would not have a material effect on the financial statements of the Company.

Another potential effect of climate change is an increase in the severity of global weather conditions. The Company manufactures a growing percentage of its HPLC, UPLC and MS products in both Singapore and Wexford, Ireland. Although the Company believes its has an adequate disaster recovery plan in place, severe weather conditions, including earthquakes, hurricanes and/or tsunami, could potentially cause significant damage to the Company’s manufacturing facilities in each of these countries. There can be no assurance that the effects of such damage and the resultant disruption of manufacturing operations would not have a materially adverse impact to the financial results of the Company.

Regulatory Compliance

The Company is subject to regulation by various federal, state and foreign governments and agencies in areas including, among others, health and safety, import/export and environmental. A portion of the Company’s operations are subject to regulation by the United States Food and Drug Administration and similar foreign agencies. These regulations are complex and govern an array of product activities, including design, development, labeling, manufacturing, promotion, sales and distribution. Any failure by the Company to comply with applicable government regulations could result in product recalls, the imposition of fines, restrictions on the Company’s ability to conduct or expand its operations or the cessation of all or a portion of its operations.

Some of the Company’s operations are subject to domestic and international laws and regulations with respect to the manufacture, handling, use or sale of toxic or hazardous substances. This requires the Company to devote substantial resources to maintain compliance with those applicable laws and regulations. If the Company fails to comply with such requirements in the manufacture or distribution of its products, it could face civil and/or criminal penalties and potentially be prohibited from distributing or selling such products until they are compliant.

Some of the Company’s products are also subject to the rules of certain industrial standards bodies, such as the International Standards Organization. The Company must comply with these rules, as well as those of other agencies such as those of the United States Occupational Health and Safety Administration. Failure to comply with such rules could result in the loss of certification and/or the imposition of fines and penalties which could have a material adverse effect on the Company’s operations.

None.

Agilent Technologies, Inc.

The Company filed suit in the United States against Hewlett-Packard Company and Hewlett-Packard GmbH (collectively, “HP”), seeking a declaration that certain products sold under the mark “Alliance” did not constitute an infringement of one or more patents owned by HP or its foreign subsidiaries (the “HP patents”). The action in the United States was dismissed for lack of controversy. Actions seeking revocation or nullification of foreign HP patents were filed by the Company in Germany, France and England. A German patent tribunal found the HP German patent to be valid. In Germany, France and England, HP and its successor, Agilent Technologies Deutschland GmbH (“Agilent”), brought actions alleging that certain features of the Alliance pump may infringe the HP patents. In England, the Court of Appeal found the HP patent valid and infringed. The Company’s petitions for leave to appeal to the House of Lords were denied. A trial on damages was scheduled for November 2004.

In March 2004, Agilent brought a new action against the Company alleging that certain features of the Alliance pump continued to infringe the HP patents. In December 2004, following a trial in the new action, the UK court ruled that the Company did not infringe the HP patents. Agilent filed an appeal in that action, which was heard in July 2005, and the UK Appellate Court upheld the lower court’s ruling of non-infringement. In December 2005, a trial on damages commenced in the first action and continued for six days prior to a holiday recess. In February 2006, the Company, HP and Agilent entered into a settlement agreement (the “Agilent Settlement Agreement”) with respect to the first action and a consent order dismissing the case was entered. The Agilent Settlement Agreement provides for the release of the Company and its UK affiliate from each and every claim under Agilent’s European patent (UK) number 309,596 arising out of the prior sale by either of them of Alliance Separations Modules incorporating the patented technology. In consideration of entering into the Agilent Settlement Agreement and the consent order, the Company made a payment to Agilent of 3.5 million British Pounds, in full and final settlement of Agilent’s claim for damages and in relation to all claims for costs and interest in the case.

In France, the Paris District Court found the HP patent valid and infringed by the Alliance pump. The Company appealed the French decision and, in April 2004, the French appeals court affirmed the Paris District Court’s finding of infringement. The Company filed a further appeal in the case and the appeal was dismissed in March 2007. In January 2009, the French appeals court affirmed that the Company had infringed the Agilent patent and a judgment was issued against the Company. The Company has appealed this judgment. In the meantime, however, the Company recorded a $7 million provision in 2008 for damages and fees estimated to be incurred in connection with this case. The accrued patent litigation expense is in other current liabilities in the consolidated balance sheets at December 31, 2009. In addition, the Company sought a declaration from the French court that, as was found in both the UK and Germany, certain modified features of the Alliance pump do not infringe the HP patents. A hearing on this matter was held in September 2007 and, in December 2007, the French court held that the modified features of the Alliance pump are non-infringing. Agilent appealed this ruling and, in January 2010, the French appeals court affirmed the finding of non-infringement with respect to the modified features of the Alliance pump.

In the German case, a German court found the patent infringed. The Company appealed the German decision and, in December 2004, the German appeals court reversed the trial court and issued a finding of non-infringement in favor of the Company. Agilent sought an appeal in that action and the appeal was heard in April 2007. Following the hearing, the German Federal Court of Justice set aside the judgment of the appeals court and remanded the case back to the appeals court for further proceedings. In 2008, the appeals court found the patent infringed. The Company has appealed this finding to the German Federal Court of Justice. In July 2005, Agilent brought a new action against the Company alleging that certain features of the Alliance pump continued to infringe the HP patents. In August 2006, following a trial in this new action, the German court ruled that the Company did not infringe the HP patents. Agilent filed an appeal in this action. A hearing on this appeal was held in January 2008. The appeals court affirmed the finding of the trial court that the Company did not infringe. Agilent has appealed this finding to the German Federal Court of Justice.

The Company recorded provisions in 2004, 2005 and 2008 for estimated damages, legal fees and court costs to be incurred with respect to this ongoing litigation. The provisions represent management’s best estimate of the probable and reasonably estimable loss related to the litigations.

City of Dearborn Heights

In November 2008, the City of Dearborn Heights Act 345 Police & Fire Retirement System filed a purported federal securities class action against the Company, Douglas Berthiaume and John Ornell in the United States District Court for the District of Massachusetts. In January 2009, Inter-Local Pension Fund GCC/IBT filed a motion to be appointed as lead plaintiff, which was granted. In April 2009, plaintiff filed an amended complaint that alleges that between July 24, 2007 and January 22, 2008, the Company misrepresented or omitted material information about its projected annual revenues and earnings, its projected effective annual tax rate and the level of business activity in Japan. The action is purportedly brought on behalf of persons who purchased common stock of the Company between July 24, 2007 and January 22, 2008. The amended complaint seeks to recover under Section 10(b) of the Exchange Act, Rule 10b-5 thereunder and Section 20(a) of the Exchange Act. The Company, Mr. Berthiaume and Mr. Ornell have filed a motion to dismiss the amended complaint, which lead plaintiff opposed. The court has not yet indicated if it will hold oral argument on the pending motion. The Company intends to defend vigorously.

Reference is made to information contained in the section entitled “Selected Financial Data” and is incorporated by reference from page 79 of this Form 10-K, included in Item 8, Financial Statements and Supplementary Data, and should be considered an integral part of this Item 6.

Business and Financial Overview

The Company’s sales were $1,499 million, $1,575 million and $1,473 million in 2009, 2008 and 2007, respectively. Sales declined 5% in 2009 as compared with 2008 and sales grew by 7% in 2008 as compared with 2007. Overall,

the 2009 decline in sales is primarily due to lower instrument spending by the Company’s customers as a result of global economic recessionary conditions and, to a lesser extent, due to the effect of foreign currency translation, which lowered sales by 2% in 2009. Companies acquired in late 2008 and early 2009 added 2% to sales in 2009 as compared to 2008. 2009 instrument system sales declined 10% while recurring sales of chemistry consumables and service increased 2% as compared with 2008, primarily from the effect of acquisitions. The 2008 sales growth as compared to 2007 was primarily attributed to the Company’s introduction of new products, the increase in chemistry consumable and service sales and the effects of foreign currency translation.

A decline in sales, as compared to the corresponding quarter in the prior year, started in the fourth quarter of 2008 due to the global economic recession and continued into the first three quarters of 2009. This decline ended in the fourth quarter of 2009 when sales increased at a rate of 3% over the 2008 fourth quarter. The increase in the 2009 fourth quarter sales is attributed to favorable currency translation, the benefit from acquisitions, a slight improvement in global economic conditions and the introduction of new products.

During 2009, as compared to 2008, sales increased 1% in Asia (including Japan) while sales decreased 4% in the U.S., 9% in Europe and 12% in the rest of the world. The effect of currency translation decreased 2009 sales by 2%. During 2008, as compared to 2007, sales increased 1% in the U.S., 7% in Europe, 16% in Asia and 3% in the rest of the world. The effect of currency translation benefited 2008 sales by approximately 2%.

In 2009, as compared to 2008, sales to pharmaceutical and industrial and food safety customers decreased 4% and 11%, respectively. These decreases are primarily a result of reduced spending on instrument systems caused by the global economic recession and, to a lesser extent, the strengthening of the U.S. dollar in developing economies, including India, South America and Eastern Europe. Global sales to government and academic customers were 5% higher in 2009 and the increase can be primarily attributed to sales of the newly introduced mass spectrometry instrument systems, higher ACQUITY UPLC^® instrument system sales and global governmental stimulus spending programs. In 2008, as compared to 2007, global sales to pharmaceutical, industrial and food safety, and government and academic customers grew 3%, 13% and 10%, respectively. The increases were primarily attributable to the demand for the Company’s new products in the U.S. and Asia, new governmental regulatory testing requirements, higher awareness of food safety issues and higher chemistry consumable and service sales.

The Waters Division’s products and services primarily consist of high performance liquid chromatography (“HPLC”), ultra performance liquid chromatography (“UPLC^®” and together with HPLC, referred to as “LC”), mass spectrometry (“MS”) and chemistry consumable products and related services. The Waters Division sales decline of 4% in 2009 as compared with 2008 was primarily attributable to weaker demand for instrument systems due to the reduction in capital spending by the Company’s customers as a result of the global recession. The Waters Division’s recurring revenue growth from chemistry consumables and service was 2% in 2009 as compared to 2008, primarily from the effect of acquisitions. The Waters Division sales grew by 7% in 2008 as compared with 2007. The Waters Division sales growth in 2008 was strongly influenced by ACQUITY UPLC sales, shipments of new Synapt^tm HDMS^tm, Xevo^tm TQ and Synapt^tm MS systems and recurring revenue growth from the service and chemistry consumables business.

In February 2009, the Company acquired all of the remaining outstanding capital stock of Thar Instruments, Inc. (“Thar”), a privately-held global leader in the design, development and manufacture of analytical and preparative supercritical fluid chromatography and supercritical fluid extraction (“SFC”) systems, for $36 million in cash, including the assumption of $4 million of debt. The Company had previously made a $4 million equity investment in Thar in June 2007. Thar added approximately $17 million of product sales and was about neutral to earnings in 2009 after debt service costs. Recently acquired companies, both Thar and the 2008 acquisition of Analytical Products Group, Inc. (“APG”), added 2% to Waters Division’s sales in 2009.

The TA Division’s (“TA^®”) products and services primarily consist of thermal analysis, rheometry and calorimetry instrument systems and service sales. Sales for TA decreased by 11% in 2009 as compared to 2008. TA’s sales decline in 2009 can be primarily attributed to a decrease in spending by the Company’s industrial customers as a result of the global economic recession. The July 2008 acquisition of VTI Corporation (“VTI”) added 1% to TA’s sales in 2009 as compared to 2008. TA’s 2008 sales growth of 10% as compared to 2007 can be primarily attributed to new product introductions, the effect of foreign currency translation and the impact of acquisitions. Acquisitions

and the effect of foreign currency translation added 3% and 2%, respectively, to TA’s 2008 sales as compared to 2007.

Operating income was $395 million, $390 million and $349 million in 2009, 2008 and 2007, respectively. The $5 million net increase in operating income in 2009 over 2008 is primarily a result of the following:

These 2009 increases were partially offset by lower gross margin dollars from lower unit volume; lower prices resulting from competitive situations in certain geographies and the impact of $6 million of expense in connection with the TA building lease termination payment and $3 million of severance costs related to a restructuring in Europe.

The $41 million net increase in operating income in 2008 over 2007 is primarily the result of the benefits from an increase in sales volume, the favorable effect of foreign currency translation and the impact of a one-time $12 million expense recorded in 2007 related to a contribution into the Waters Employee Investment Plan. The 2008 increase was partially offset by a patent litigation provision of $7 million and a $9 million impact of an out-of-period capitalized software amortization adjustment recorded during 2008. During 2008, the Company identified errors originating in periods prior to the three months ended June 28, 2008. The errors primarily relate to (i) an overstatement of the Company’s income tax expense of $16 million as a result of errors in recording its income tax provision during the period from 2000 to March 29, 2008 and (ii) an understatement of amortization expense of $9 million for certain capitalized software. The Company incorrectly calculated its provision for income taxes by tax-effecting its tax liability utilizing a U.S. tax rate of 35% instead of an Irish tax rate of approximately 10%. In addition, the Company incorrectly accounted for Irish-based capitalized software and the related amortization expense as U.S. Dollar-denominated instead of Euro-denominated, resulting in an understatement of amortization expense and cumulative translation adjustment. For 2008, the errors reduced the Company’s effective tax rate by 4.0 percentage points.

In 2009, the Company recorded approximately $5 million of tax benefit associated with the reversal of a $5 million tax provision which was originally recorded in 2008 relating to the reorganization of certain foreign legal entities. The recognition of this tax benefit was a result of changes in income tax regulations promulgated by the U.S. Treasury in February 2009. The tax benefit recognized in 2009 decreased the Company’s effective tax rate by 1.2 percentage points for 2009. The one-time tax provision recorded in 2008 increased the Company’s effective tax rate by 1.4 percentage points in 2008.

Net income per diluted share was $3.34, $3.21 and $2.62 in 2009, 2008 and 2007, respectively. Net income per diluted share grew at a rate of 4% in 2009 as compared with 2008 and 23% in 2008 as compared with 2007. Net income per diluted share was primarily impacted by the following factors in 2009, 2008 and 2007:

Net cash provided by operating activities was $418 million, $418 million and $371 million in 2009, 2008 and 2007, respectively. The 2009 cash provided by operating activities was consistent with the 2008 cash provided by operating activities despite the lower sales volume and the global economic recession. The $47 million increase in the operating cash flow in 2008 as compared to 2007 was primarily the result of higher net income and improved cash collections from customers, partially offset by a $13 million one-time transition benefit payment into the Waters Employee Investment Plan that was expensed in 2007, increases in inventory and the timing of payments to vendors.

Within cash flows used in investing activities, capital expenditures related to property, plant, equipment and software capitalization were $94 million, $69 million and $60 million in 2009, 2008 and 2007, respectively. The increase in capital expenditures in 2009 is primarily attributed to $28 million spent to acquire land and construct a new TA facility, which was completed in 2009. In February 2009, the Company acquired all of the remaining outstanding capital stock of Thar for $36 million in cash. The Company made an equity investment in Thar in June 2007 for $4 million in cash. The Company continues to evaluate the acquisition of businesses, product lines and technologies to augment the Waters and TA operating divisions.

Within cash flows used in financing activities, the Company received $19 million, $29 million and $91 million of proceeds from stock plans in 2009, 2008 and 2007, respectively. Fluctuations in these amounts are primarily attributed to changes in the Company’s stock price and the expiration of stock option grants. In February 2009, the Company’s Board of Directors authorized the Company to repurchase up to $500 million of its outstanding common stock over a two-year period. During 2009, 2008 and 2007, the Company repurchased 4.5 million, 4.1 million and 3.4 million shares at a cost of $210 million, $235 million and $201 million, respectively, under the February 2009 authorization and previously announced stock repurchase programs. The Company believes that it has the financial flexibility to fund these share repurchases given current cash and debt levels, as well as to invest in research, technology and business acquisitions to further grow the Company’s sales and profits.

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

Net Sales

Net sales for 2009 and 2008 were $1,499 million and $1,575 million, respectively, a decrease of 5%. The effect of foreign currency translation lowered sales in 2009 by 2%. Product sales were $1,052 million and $1,140 million for 2009 and 2008, respectively, a decrease of 8%. The decrease in product sales in 2009 as compared to 2008 was primarily due to the overall decline in Waters and TA instrument system sales due to lower spending by the Company’s customers as a result of the global economic recession and adverse effects from foreign currency translation. Service sales were $447 million and $435 million in 2009 and 2008, respectively, an increase of 3%. The increase in service sales in 2009 as compared with 2008 was primarily attributable to increased sales of service plans and billings to a higher installed base of customers.

Waters Division Net Sales

The Waters Division net sales declined 4% in 2009 as compared to 2008. The effect of foreign currency translation negatively impacted the Waters Division across all product lines, resulting in a decline in total sales of 2%. The 2009 acquisition of Thar and 2008 acquisition of APG added 2% to sales in 2009.

Chemistry consumables sales in 2009 were comparable to 2008, with the effect of foreign currency translation negatively impacting chemistry consumable sales by 2%. Waters Division service sales grew 3% in 2009 due to increased sales of service plans and billings to a higher installed base of customers. The service sales growth rate was negatively impacted by 1% from the effect of foreign currency translation. Waters instrument system sales (LC and MS) declined by 9% in 2009. The decrease in instrument system sales is primarily attributable to weak industrial and pharmaceutical customer spending caused by the global recession. The effect of foreign currency translation negatively impacted the 2009 instrument system sales by 2%. Waters Division sales by product line in 2009 were 52% for instrument systems, 18% for chemistry consumables and 30% for service, as compared to 55% for instrument systems, 17% for chemistry consumables and 28% for service in 2008.

Waters Division sales in Europe declined 9%, primarily due to weak demand in Eastern Europe and the effects of foreign currency translation, which decreased 2009 sales in Europe by 6%. Waters Division sales in Asia increased 2% in 2009, with strong sales growth in China partially offset by weakness in other Asian markets. The effects of foreign currency translation increased Asia’s 2009 sales by 2%. Waters Division sales in the U.S. and the rest of the world declined 2% and 13%, respectively. The effects of foreign currency translation decreased 2009 sales in the rest of world by 3%.

TA Division Net Sales

TA’s sales were 11% lower in 2009 as compared to 2008 primarily as a result of weak instrument system demand from its industrial customers. Foreign currency translation had minimal impact on TA’s 2009 sales as compared to 2008. The 2008 acquisition of VTI added 1% to sales in 2009. Instrument system sales declined 15% in 2009 and represented 74% of sales in 2009 as compared to 78% in 2008. TA service sales increased by 4% in 2009 due to the increased sales of service plans and billings to a higher installed base of customers. Geographically, TA sales decreased in each market.

Gross Profit

Gross profit for 2009 was $904 million compared to $914 million for 2008, a decrease of $10 million, or 1%. Gross profit as a percentage of sales increased to 60.3% in 2009 compared to 58.0% for 2008. The decrease in gross profit dollars in 2009 can be primarily attributed to the lower sales volume and lower prices in certain geographies offset by the benefits from net favorable foreign currency translation, a favorable change in sales mix and lower manufacturing costs. Gross profit in 2008 also had a $9 million charge from out-of-period adjustments related to capitalized software amortization. During 2009, the Company’s gross profit as a percentage of sales benefited from the favorable movements in certain foreign exchange rates between the currencies where the Company manufactures and services products and the currencies where the sales were transacted, principally the Euro, Japanese Yen and British Pound. Gross profit as a percentage of sales was also primarily impacted by the change in sales mix, with 2009 containing a higher level of higher margin chemistry consumables and service sales than 2008.

Selling and Administrative Expenses

Selling and administrative expenses for 2009 and 2008 were $421 million and $427 million, respectively, a decrease of 1%. The decrease in 2009 selling and administrative expenses is primarily due to tighter control of discretionary spending including no merit increase in 2009, lower incentive compensation and the comparative favorable impact of foreign currency translation. The 2009 decreases were offset by the impact of the $6 million expense incurred in connection with the TA lease termination payment. As a percentage of net sales, selling and administrative expenses were 28.1% for 2009 compared to 27.1% for 2008. This percentage increase can be attributed to the lower 2009 sales volume.

Research and Development Expenses

Research and development expenses were $77 million and $82 million for 2009 and 2008, respectively, a decrease of $5 million, or 5%. The decrease in research and development expenses in 2009 is primarily due to the comparative favorable impact of foreign currency translation.

Interest Expense

Interest expense was $11 million and $39 million for 2009 and 2008, respectively. The decrease in interest expense in 2009 is primarily attributable to a decrease in average borrowings, as well as significantly lower interest rates during 2009 as compared to 2008.

Interest Income

Interest income was $3 million and $21 million for 2009 and 2008, respectively. The decrease in interest income is primarily due to significantly lower yields during 2009 as compared to 2008, as well as lower average cash and short-term investment balances.

Provision for Income Taxes

The Company’s effective tax rates for 2009 and 2008 were 16.4% and 13.4%, respectively. Included in the income tax provision for 2009 is approximately $5 million of tax benefit relating to the reversal of a $5 million provision which was originally recorded in 2008 relating to the reorganization of certain foreign legal entities. The recognition of this tax benefit in 2009 was a result of changes in income tax regulations promulgated by the U.S. Treasury in February 2009. The $5 million tax benefit decreased the Company’s effective tax rate by 1.2 percentage points in 2009. The one-time provision increased the Company’s effective tax rate by 1.4 percentage points in 2008. In addition, the effective tax rate for 2008 included a $16 million benefit resulting from out-of-period adjustments related to software capitalization amortization. The out-of-period adjustments had the effect of reducing the Company’s effective tax rate by 4.0 percentage points in 2008. After consideration of these items, the remaining change in the effective tax rates for 2009 as compared to 2008 is primarily attributable to changes in income in jurisdictions with different effective tax rates.

Year Ended December 31, 2008 Compared to Year Ended December 31, 2007

Net sales for 2008 and 2007 were $1,575 million and $1,473 million, respectively, an increase of 7%. Foreign currency translation benefited sales growth for 2008 by 2%. Product sales were $1,140 million and $1,088 million for 2008 and 2007, respectively, an increase of 5%. The increase in product sales was primarily due to the overall positive growth in Waters and TA instrument systems, chemistry consumables and foreign currency translation benefits. Service sales were $435 million and $385 million in 2008 and 2007, respectively, an increase of 13%. The increase in service sales was primarily attributable to increased sales of service plans and billings to a higher installed base of customers and foreign currency translation benefits.

The Waters Division net sales grew 7% in 2008 as compared to 2007. The effect of foreign currency translation benefited the Waters Division across all product lines, resulting in a benefit to total sales growth of 2%.

Chemistry consumables sales grew 9% in 2008 as compared to 2007. This growth was driven by increased column sales of ACQUITY UPLC proprietary column technology and sales of HPLC columns. Waters Division service sales grew 12% in 2008 due primarily to increased sales of service plans and billings to a higher installed base of customers. Waters instrument system sales grew 3% in 2008. The increase in instrument system sales during 2008 is primarily attributable to higher sales of ACQUITY UPLC, Synapt HDMS, Synapt MS and the Xevo TQ. Sales were negatively impacted by the slowdown in industrial customer spending which occurred during the fourth quarter of 2008 due to the economic recession. Waters Division sales by product line were essentially unchanged in 2008 and 2007 with instrument systems, chemistry consumables and service representing approximately 55%, 17% and 28% of sales, respectively.

Geographically, Waters Division sales in Europe, Asia and the rest of the world grew approximately 6%, 17% and 4% in 2008, respectively. Sales in the U.S. were flat in 2008. The sales growth in 2008 was primarily due to higher demand from the Company’s government, academic and industrial customers. Asia’s sales growth was primarily driven by increased sales in India and China. The effects of foreign currency translation increased sales growth in Europe and Asia by 4% and 5% in 2008, respectively.

TA’s sales grew 10% in 2008 as compared to 2007 primarily as a result of new product introductions, acquisitions and the effect of foreign currency translation. The effect of foreign currency translation benefited the TA sales growth by 2% in 2008 as compared to 2007. Instrument system sales grew 6% and represented approximately 78% and 81% of sales in 2008 and 2007, respectively. TA service sales grew 27% in 2008 and can be primarily attributed to a higher installed base of customers and new service sales to the customers of recently acquired companies. Geographically, sales growth for TA in 2008 was predominantly in the U.S., Europe and Asia. The July 2008 VTI acquisition and the August 2007 acquisition of CSC added 3% to TA’s sales growth for 2008.

Gross profit for 2008 was $914 million compared to $842 million for 2007, an increase of $72 million, or 9%. Gross profit as a percentage of sales increased to 58.0% in 2008 compared to 57.2% in 2007. This increase is primarily due to higher sales volume, increased comparative benefits of foreign currency translation and, to a lesser extent, lower manufacturing costs. Also, the overall gross profit increase was negatively impacted by a $9 million out-of-period capitalized software amortization adjustment recorded during 2008. The gross profit increase can also be attributed to a $3 million expense recorded in 2007 relating to the contribution into the Waters Employee Investment Plan.

Selling and administrative expenses for 2008 and 2007 were $427 million and $404 million, respectively, an increase of 6%. Included in selling and administrative expenses for 2007 is the impact of a one-time $7 million expense related to the contribution into the Waters Employee Investment Plan. The remaining $16 million increase in total selling and administrative expenses for 2008 is primarily due to annual merit increases, modest headcount additions to support increased sales volume and the comparative unfavorable impact of foreign currency translation. As a percentage of net sales, selling and administrative expenses were 27.1% for 2008 compared to 27.4% for 2007.

Research and development expenses were $82 million and $81 million for 2008 and 2007, respectively, an increase of $1 million, or 1%. Included in research and development expenses for 2007 is $2 million of expense related to the contribution into the Waters Employee Investment Plan. The remaining increase in research and development expenses for 2008 is primarily due to the timing of new product introduction costs, annual merit increases and modest headcount additions.

Litigation Provision

The Company recorded a $7 million provision in 2008 for damages and fees estimated to be incurred in connection with a judgment issued against the Company relating to an ongoing patent infringement lawsuit with Agilent Technologies Inc.

Interest expense was $39 million and $57 million for 2008 and 2007, respectively. The decrease in interest expense is primarily attributable to a decrease in average borrowing costs and lower average borrowings during 2008 as compared to 2007.

Interest income was $21 million and $31 million for 2008 and 2007, respectively. The decrease in interest income is primarily due to lower yields and lower cash and short-term investment balances.

The Company’s effective tax rates for 2008 and 2007 were 13.4% and 17.1%, respectively. Included in the income tax provision for 2008 is approximately $5 million of tax provision associated with the reorganization of certain foreign legal entities. This one-time provision increased the Company’s effective tax rate by 1.4 percentage points in 2008. In addition, the effective tax rate for 2008 included a $16 million benefit resulting from out-of-period adjustments related to software capitalization amortization. The out-of-period adjustments had the effect of reducing the Company’s effective tax rate by 4.0 percentage points in 2008. The 2007 tax provision includes a $4 million tax benefit associated with a one-time contribution into the Waters Employee Investment Plan. The remaining decrease in the effective tax rate for 2008 is primarily attributable to proportionately greater growth in income in jurisdictions with comparatively lower effective tax rates.

Net cash provided by operating activities was $418 million in both 2009 and 2008. The changes within net cash provided from operating activities in 2009 as compared to 2008 include the following significant changes in the sources and uses of net cash provided by operating activities, aside from the increase in net income:

Year Ended December 31, 2008 Compared to Year Ended December 31, 2007

Net cash provided by operating activities was $418 million and $371 million in 2008 and 2007, respectively. The $47 million increase in net cash provided from operating activities in 2008 as compared to 2007 is attributed primarily to the following significant changes in the sources and uses of net cash provided from operating activities, aside from the increase in net income:

Cash Used in Investing Activities

Net cash used in investing activities totaled $419 million in 2009. Net cash provided by investing activities totaled $19 million in 2008. Net cash used in investing activities totaled $168 million in 2007. Additions to fixed assets and capitalized software were $94 million in 2009, $69 million in 2008 and $60 million in 2007. The increase in capital spending in 2009 can be attributed primarily to $28 million spent to acquire land and construct a new TA facility, which was completed in 2009. Capital spending returned to 2008 levels beginning in the fourth quarter of 2009; however, capital spending may increase periodically in the future in order to fund other facility expansions to accommodate future sales growth. During 2009, 2008 and 2007, the Company purchased $518 million, $20 million and $391 million of short-term investments, respectively, while $229 million, $115 million and $295 million of short-term investments matured, respectively. Business acquisitions, net of cash acquired, were $36 million, $8 million and $9 million in 2009, 2008 and 2007, respectively.

Cash Used in Financing Activities

In February 2010, the Company issued and sold five-year senior unsecured notes at an interest rate of 3.75% with a face value of $100 million. This debt matures in February 2015. In addition, in early March 2010, the Company expects to issue and sell ten-year senior unsecured notes at an interest rate of 5.00% with a face value of $100 million. This debt would mature in February 2020. The Company plans to use the proceeds from the issuance of these senior unsecured notes to repay other outstanding debt amounts and for general corporate purposes. Interest on both issuances of the senior unsecured notes are payable semi-annually in February and August of each year. The Company may redeem some or all of the notes at any time in an amount not less than 10% of the aggregate principal amount outstanding, plus accrued and unpaid interest, plus the applicable make-whole amount. These notes require that the Company comply with an interest coverage ratio test of not less than 3.50:1 and a leverage ratio test of not more than 3.50:1 for any period of four consecutive fiscal quarters, respectively. In addition, these notes include negative covenants that are similar to the existing credit agreement. These notes also contain certain customary representations and warranties, affirmative covenants and events of default.

During 2009, the Company’s net debt borrowings increased by $92 million. During 2008 and 2007, the Company’s net debt borrowings decreased $348 million and $19 million, respectively.

In March 2008, the Company entered into a credit agreement (the “2008 Credit Agreement”) that provided for a $150 million term loan facility. In January 2007, the Company entered into a credit agreement (the “2007 Credit Agreement”) that provides for a $500 million term loan facility and $600 million in revolving facilities, which include both a letter of credit and a swingline subfacility. Both credit agreements were to mature on January 11, 2012 and required or require no scheduled prepayments before that date. The Company uses the revolving line of credit to fund its working capital needs.

In October 2008, the Company utilized cash balances associated with the effective liquidation of certain foreign legal entities into the U.S. to voluntarily prepay the $150 million term loan under the 2008 Credit Agreement. The repayment of the term loan effectively terminated all lending arrangements under the 2008 Credit Agreement.

The interest rates applicable to the 2007 Credit Agreement are, at the Company’s option, equal to either the base rate (which is the higher of the prime rate or the federal funds rate plus 1/2%) or the applicable 1, 2, 3, 6, 9 or 12 month LIBOR rate, in each case, plus an interest rate margin based upon the Company’s leverage ratio, which can range between 33 basis points and 72.5 basis points for LIBOR rate loans and range between zero basis points and 37.5 basis points for base rate loans. The 2007 Credit Agreement requires that the Company comply with an interest coverage ratio test of not less than 3.50:1 and a leverage ratio test of not more than 3.25:1 for any period of four consecutive fiscal quarters, respectively. In addition, the 2007 Credit Agreement includes negative covenants that are customary for investment grade credit facilities. The 2007 Credit Agreement also contains certain customary representations and warranties, affirmative covenants and events of default.

As of December 31, 2009, the Company had a total of $620 million borrowed under the 2007 Credit Agreement. The Company had $500 million classified as long-term debt and $120 million classified as short-term debt from this credit agreement and various other lines of credit. The Company has classified the revolving portion of the credit agreement as short-term debt as it is the Company’s intention to pay the outstanding revolving line of credit balance during the subsequent twelve months following the respective period end date. As of December 31, 2009, the total amount available to borrow under the 2007 Credit Agreement was $479 million after outstanding letters of credit.

In February 2009, the Company’s Board of Directors authorized the Company to repurchase up to $500 million of its outstanding common stock over a two-year period. During 2009, the Company repurchased 3.1 million shares at a cost of $157 million under this program, leaving $343 million authorized for future repurchases. The Company repurchased 4.5 million, 4.1 million and 3.4 million shares at a cost of $210 million, $235 million and $201 million during 2009, 2008 and 2007, respectively, under the February 2009 authorization and previously announced programs.

The Company received $19 million, $29 million and $91 million of proceeds from the exercise of stock options and the purchase of shares pursuant to the Company’s employee stock purchase plan in 2009, 2008 and 2007, respectively. Fluctuations in these amounts are primarily attributed to the changes in the Company’s stock price and the expiration of stock option grants.

The Company believes that the cash, cash equivalents and short-term investments balance of $630 million as of December 31, 2009 and expected cash flow from operating activities, together with borrowing capacity from committed credit facilities, will be sufficient to fund working capital, capital spending requirements, authorized share repurchase amounts, potential acquisitions and any adverse final determination of ongoing litigation for at least the next twelve months. Management believes, as of the date of this report, that its financial position, along with expected future cash flows from earnings based on historical trends and the ability to raise funds from external sources, will be sufficient to meet future operating and investing needs for the foreseeable future.

The Company’s cash equivalents represent highly liquid investments, with original maturities of generally 90 days or less, in bank deposits; U.S., German, French and Dutch Government Treasury Bills; AAA rated U.S. Treasury Bills and European government bond money market funds. Similar investments with longer maturities are classified as short-term investments. Cash equivalents and short-term investments are convertible

to a known amount of cash and carry an insignificant risk of change in market value. The Company maintains balances in various operating accounts in excess of federally insured limits, and in foreign subsidiary accounts in currencies other than U.S. dollars.

Contractual Obligations and Commercial Commitments

Letters of credit

The Company licenses certain technology and software from third parties, which expire at various dates through 2010. Fees paid for licenses were less than $1 million each in 2009, 2008 and 2007. Future minimum license fees payable under existing license agreements as of December 31, 2009 are immaterial.

From time to time, the Company and its subsidiaries are involved in various litigation matters arising in the ordinary course of business. The Company believes it has meritorious arguments in its current litigation matters and any outcome, either individually or in the aggregate, will not be material to the Company’s financial position or results of operations. Current litigation is described in Item 3, Legal Proceedings, of Part I of this Form 10-K.

The Company has long-term liabilities for deferred employee compensation, including pension and supplemental executive retirement plans. The payments related to the supplemental retirement plan are not included above since they are dependent upon when the employee retires or leaves the Company and whether the employee elects lump-sum or annuity payments. During fiscal year 2010, the Company expects to contribute approximately $3 million to $5 million to the Company’s defined benefit plans. Capital expenditures in 2009 were higher than in 2008 primarily due to the $28 million spent to acquire land and construct a new TA facility, which was completed in 2009. Capital spending is expected to return to 2008 levels in 2010 and may increase periodically in the future in order to fund other facility expansions to accommodate future sales growth.

The Company accounts for its uncertain tax return reporting positions in accordance with the income taxes accounting standard, which requires financial statement reporting of the expected future tax consequences of uncertain tax return reporting positions on the presumption that all relevant tax authorities possess full knowledge of those tax reporting positions, as well as all of the pertinent facts and circumstances, but it prohibits any discounting of any of the related tax effects for the time value of money. If all of the Company’s unrecognized tax benefits accrued as of December 31, 2009 were to become recognizable in the future, the Company would record a total reduction of approximately $78 million in the income tax provision. The Company’s uncertain tax positions are taken with respect to income tax return reporting periods beginning after December 31, 1999, which are the periods

that generally remain open to income tax audit examination by the various income tax authorities. As of December 31, 2009, the Company expects that a tax audit of one of the Company’s U.K. affiliates’ tax returns for 2003, 2004 and 2005 will be settled before December 31, 2010. As of December 31, 2009, the Company does not expect the settlement of that audit to have a material effect on its consolidated financial statements. In addition, the Company has monitored and will continue to monitor the lapsing of statutes of limitations on potential tax assessments for related changes in the measurement of unrecognized tax benefits, related net interest and penalties, and deferred tax assets and liabilities. Other than the aforementioned tax audit, as of December 31, 2009, the Company does not expect to record any material changes in the measurement of unrecognized tax benefits, related net interest and penalties or deferred tax assets and liabilities due to the settlement of tax audit examinations or to the lapsing of statutes of limitations on potential tax assessments within the next twelve months.

The Company has not paid any dividends and does not plan to pay any dividends in the foreseeable future.

Off-Balance Sheet Arrangements

The Company has not created, and is not party to, any special-purpose or off-balance sheet entities for the purpose of raising capital, incurring debt or operating parts of its business that are not consolidated (to the extent of the Company’s ownership interest therein) into the consolidated financial statements. The Company has not entered into any transactions with unconsolidated entities whereby it has subordinated retained interests, derivative instruments or other contingent arrangements that expose the Company to material continuing risks, contingent liabilities or any other obligation under a variable interest in an unconsolidated entity that provides financing, liquidity, market risk or credit risk support to the Company.

Critical Accounting Policies and Estimates

Summary

The preparation of consolidated financial statements requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent liabilities. Critical accounting policies are those that are central to the presentation of the Company’s financial condition and results of operations that require management to make estimates about matters that are highly uncertain and that would have a material impact on the Company’s results of operations given changes in the estimate that are reasonably likely to occur from period to period or use of different estimates that reasonably could have been used in the current period. On an ongoing basis, the Company evaluates its policies and estimates. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. There are other items within the Company’s consolidated financial statements that require estimation, but are not deemed critical as defined above. Changes in estimates used in these and other items could potentially have a material impact on the Company’s consolidated financial statements.

Revenue Recognition

Sales of products and services are generally recorded based on product shipment and performance of service, respectively. Proceeds received in advance of product shipment or performance of service are recorded as deferred revenue in the consolidated balance sheets. Shipping and handling costs are included in cost of sales net of amounts invoiced to the customer per the order. The Company’s products generally carry one year of warranty. These costs are accrued at the point of shipment. Once the warranty period has expired, the customer may purchase a service contract. Service contract billings are generally invoiced to the customer at the beginning of the contract term and revenue is amortized on a straight-line basis over the contract term. At December 31, 2009, the Company had current and long-term deferred revenue liabilities of $95 million and $16 million, respectively.

Product shipments, including those for demonstration or evaluation, and service contracts are not recorded as revenues until a valid purchase order or master agreement is received specifying fixed terms and prices. Revenues are adjusted accordingly for changes in contract terms or if collectibility is not reasonably assured. The Company’s method of revenue recognition for certain products requiring installation is in accordance with accounting standards

for revenue recognition. Accordingly, revenue is recognized when all of the following criteria are met: persuasive evidence of an arrangement exists; delivery has occurred; the vendor’s fee is fixed or determinable; collectibility is reasonably assured and, if applicable, upon acceptance when acceptance criteria with contractual cash holdback are specified. With respect to installation obligations, the larger of the contractual cash holdback or the fair value of the installation service is deferred when the product is shipped and revenue is recognized as a multiple-element arrangement when installation is complete. The Company determines the fair value of installation based upon a number of factors, including hourly service billing rates, estimated installation hours and comparisons of amounts charged by third parties. The Company believes that this amount approximates the amount that a third party would charge for the installation effort.

Sales of software are accounted for in accordance with the accounting standards for software revenue recognition. Software revenue is recognized upon shipment, as typically no significant post-delivery obligations remain. Software upgrades are typically sold as part of a service contract, with revenue recognized ratably over the term of the service contract.

Loss Provisions on Accounts Receivable and Inventory

The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. If the financial condition of the Company’s customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. The Company does not request collateral from its customers, but collectibility is enhanced through the use of credit card payments and letters of credit. The Company assesses collectibility based on a number of factors including, but not limited to, past transaction history with the customer, the credit-worthiness of the customer, industry trends and the macro-economic environment. Historically, the Company has not experienced significant bad debt losses. Sales returns and allowances are estimates of future product returns related to current period revenue. Material differences may result in the amount and timing of revenue for any period if management made different judgments or utilized different estimates for sales returns and allowances for doubtful accounts. The Company’s accounts receivable balance at December 31, 2009 was $314 million, net of allowances for doubtful accounts and sales returns of $7 million.

The Company values all of its inventories at the lower of cost or market on a first-in, first-out basis (“FIFO”). The Company estimates revisions to its inventory valuations based on technical obsolescence; historical demand; projections of future demand, including that in the Company’s current backlog of orders; and industry and market conditions. If actual future demand or market conditions are less favorable than those projected by management, additional write-downs may be required. The Company’s inventory balance at December 31, 2009 was $179 million, net of write-downs to net realizable value of $13 million.

Long-Lived Assets, Intangible Assets and Goodwill

The Company assesses the impairment of identifiable intangibles, long-lived assets and goodwill whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Factors the Company considers important which could trigger an impairment review include, but are not limited to, the following:

When the Company determines that the carrying value of an individual intangible asset, long-lived asset or goodwill may not be recoverable based upon the existence of one or more of the above indicators, an estimate of undiscounted future cash flows produced by that intangible asset, long-lived asset or goodwill, including its eventual residual value, is compared to the carrying value to determine whether impairment exists. In the event that such cash flows are not expected to be sufficient to recover the carrying amount of the asset, the asset is written-down to its estimated fair value. Net intangible assets, long-lived assets and goodwill amounted to $182 million, $211 million and $293 million, respectively, as of December 31, 2009. The Company performs annual impairment reviews of its goodwill. The Company performed its annual review during the fourth quarter of 2009 and currently

does not expect to record an impairment charge in the foreseeable future. However, there can be no assurance that, at the time future reviews are completed, a material impairment charge will not be recorded.

Warranty

Product warranties are recorded at the time revenue is recognized for certain product shipments. While the Company engages in extensive product quality programs and processes, including actively monitoring and evaluating the quality of its component suppliers, the Company’s warranty obligation is affected by product failure rates, material usage and service delivery costs incurred in correcting a product failure. Should actual product failure rates, material usage or service delivery costs differ from the Company’s previous estimates, revisions to the estimated warranty liability would be required. At December 31, 2009, the Company’s warranty liability was $10 million.

Income Taxes

As part of the process of preparing the consolidated financial statements, the Company is required to estimate its income taxes in each of the jurisdictions in which it operates. This process involves the Company estimating its actual current tax exposure together with assessing changes in temporary differences resulting from differing treatment of items, such as depreciation, amortization and inventory reserves, for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included within the consolidated balance sheets. In the event that actual results differ from these estimates, or the Company adjusts these estimates in future periods, the Company may need to establish an additional valuation allowance which could materially impact its financial position and results of operations.

The accounting standard for income taxes requires that a company continually evaluate the necessity of establishing or changing a valuation allowance for deferred tax assets, depending on whether it is more likely than not that actual benefit of those assets will be realized in future periods. In addition, the Company accounts for its uncertain tax return reporting positions in accordance with the income taxes accounting standard, which requires financial statement reporting of the expected future tax consequences of uncertain tax return reporting positions on the presumption that all relevant tax authorities possess full knowledge of those tax reporting positions, as well as all of the pertinent facts and circumstances, but it prohibits any discounting of any of the related tax effects for the time value of money. At December 31, 2009, the Company had unrecognized tax benefits of $78 million.

Litigation

As described in Item 3, Legal Proceedings, of Part I of this Form 10-K, the Company is a party to various pending litigation matters. With respect to each pending claim, management determines whether it can reasonably estimate whether a loss is probable and, if so, the probable range of that loss. If and when management has determined, with respect to a particular claim, both that a loss is probable and that it can reasonably estimate the range of that loss, the Company records a charge equal to either its best estimate of that loss or the lowest amount in that probable range of loss. The Company will disclose additional exposures when the range of loss is subject to considerable interpretation.

With respect to the claims referenced in Item 3, management of the Company to date has been able to make this determination and thus has recorded charges with respect to the claims described in Item 3. As developments occur in these matters and additional information becomes available, management of the Company will reassess the probability of any losses and of their range, which may result in its recording charges or additional charges which could materially impact the Company’s results of operation or financial position.

Pension and Other Retirement Benefits

Assumptions used in determining projected benefit obligations and the fair values of plan assets for the Company’s pension plans and other retirement benefits are evaluated periodically by management. Changes in assumptions are based on relevant company data. Critical assumptions, such as the discount rate used to measure the benefit obligations and the expected long-term rate of return on plan assets, are evaluated and updated annually. The Company has assumed that the weighted-average expected long-term rate of return on plan assets will be 7.95% for its U.S. benefit plans and 3.34% for its Non-U.S. benefit plans.

At the end of each year, the Company determines the discount rate that reflects the current rate at which the pension liabilities could be effectively settled. The Company determined the discount rate based on the analysis of the Mercer and Citigroup Pension Discount Curves for high quality investments and the Moody’s Aa interest rate as of December 31, 2009 that best matched the timing of the plan’s future cash flows for the period to maturity of the pension benefits. Once the interest rates were determined, the plan’s cash flow was discounted at the spot interest rate back to the measurement date. At December 31, 2009, the Company determined the weighted-average discount rate to be 5.95% for the U.S. benefit plans and 4.05% for the Non-U.S. benefits plans.

A one-quarter percentage point increase in the discount rate would decrease the Company’s net periodic benefit cost for the Waters Retirement Plan by less than $1 million. A one-quarter percentage point increase in the assumed long-term rate of return would decrease the Company’s net periodic benefit cost for the Waters Retirement Plan by less than $1 million.

Stock-based Compensation

The accounting standard for stock-based compensation requires that all share-based payments to employees be recognized in the statements of operations based on their fair values. The Company has used the Black-Scholes model to determine the fair value of its stock option awards. Under the fair-value recognition provisions of this statement, share-based compensation cost is measured at the grant date based on the value of the award and is recognized as expense over the vesting period. Determining the fair value of share-based awards at the grant date requires judgment, including estimating stock price volatility and employee stock option exercise behaviors. If actual results differ significantly from these estimates, stock-based compensation expense and the Company’s results of operations could be materially impacted. As stock-based compensation expense recognized in the consolidated statements of operations is based on awards that ultimately are expected to vest, the amount of expense has been reduced for estimated forfeitures. This accounting standard requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Forfeitures were estimated based on historical experience. If factors change and the Company employs different assumptions in the application of this accounting standard, the compensation expense that the Company records in the future periods may differ significantly from what the Company has recorded in the current period.

The Company adopted the modified prospective transition method permitted under the stock-based compensation accounting standard and, consequently, has not adjusted results from prior years. Under the modified transition method, compensation costs now include expense relating to the remaining unvested awards granted prior to December 31, 2005 and the expense related to any awards issued subsequent to December 31, 2005. The Company recognizes the expense using the straight-line attribution method.

As of December 31, 2009, unrecognized compensation costs and related weighted-average lives over which the costs will be amortized were as follows (in millions):

Recent Accounting Standards Changes

Recently Adopted Accounting Standards

In June 2009, a new accounting standard was issued that establishes the hierarchy of Generally Accepted Accounting Principles (“GAAP”) that are to be used as the source of authoritative accounting principles recognized by the Financial Accounting Standards Board (“FASB”) for non-governmental entities in preparation of financial statements in conformity with GAAP in the United States. This standard was effective for interim and annual periods ending after September 15, 2009. The adoption of this standard by the Company did not have a material effect on its financial position, results of operations or cash flows.

In August 2009, a new accounting standard was issued for measuring liabilities at fair value. This standard provides clarification that, in circumstances in which a quoted price in an active market for the identical liability is not available, a reporting entity is required to measure fair value using one or more of the following methods: (1) a valuation technique that uses (a) the quoted price of the identical liability when traded as an asset or (b) quoted prices for similar liabilities or similar liabilities when traded as assets; and/or (2) a valuation technique that is consistent with GAAP. This standard also clarifies that when estimating the fair value of a liability, a reporting entity is not required to adjust to include inputs relating to the existence of transfer restrictions on that liability. The adoption of this standard did not have a material effect on the Company’s financial position, results of operations or cash flows.

In April 2009, a new accounting standard was issued to provide greater clarity about the credit and noncredit component of an other-than-temporary impairment event and to more effectively communicate when an other-than-temporary impairment event has occurred. This standard applies to debt securities. This standard was effective for periods ending after June 15, 2009. The adoption of this standard did not have a material effect on the Company’s financial position, results of operations or cash flows.

In April 2009, a new accounting standard was issued to require disclosures about fair value of financial instruments in interim as well as in annual financial statements. This standard was effective for periods ending after June 15, 2009. The adoption of this standard did not have a material effect on the Company’s financial position, results of operations or cash flows.

In the second quarter of 2009, the Company implemented the newly issued subsequent events accounting standard. This standard establishes general standards of accounting for and disclosure of events that occur after the balance sheet date, but before financial statements are issued. The adoption of this standard did not impact the Company’s financial position or results of operations. The Company evaluated all events or transactions that occurred after December 31, 2009 up through February 26, 2010, the date the Company issued these financial statements. During this period, the Company did not have any material recognizable subsequent events which have not been disclosed.

In December 2008, a new accounting standard was issued relating to the employers’ disclosures about postretirement benefit plan assets. This requirement amends the previous accounting standard to provide guidance on employers’ disclosures about plan assets of a defined benefit pension or other postretirement plan. This new standard is effective for financial statements issued for fiscal years ending after December 15, 2009. The provisions of this new standard are not required for earlier periods presented and early adoption is permitted. The adoption of this standard did not have an effect on the Company’s financial position, results of operations or cash flows.

Recently Issued Accounting Standards

In June 2009, a new accounting standard was issued relating to the consolidation of variable interest entities. This statement addresses (1) the effects on certain provisions on existing accounting standards as a result of the elimination of the qualifying special-purpose entity concept and (2) constituent concerns about the application of certain key provisions of existing accounting standards, including those in which the accounting and disclosures under existing accounting standards do not always provide timely and useful information about an enterprise’s involvement in a variable interest entity. This standard is effective for periods beginning after November 15, 2009. The adoption of this standard will not have a material effect on its financial position, results of operations or cash flows.

elements in the arrangement was not determinable, then revenue was deferred until all of the items were delivered or fair value was determined. This new approach is effective prospectively for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010. The Company is in the process of evaluating whether the adoption of this standard will have a material effect on its financial position, results of operations or cash flows.

In October 2009, a new accounting consensus was issued for certain revenue arrangements that include software elements. This consensus amends the existing accounting guidance for revenue arrangements that contain tangible products and software. This consensus requires that tangible products which contain software components and non-software components that function together to deliver the tangible products essential functionality are no longer within the scope of the software revenue guidance. This new approach is effective prospectively for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010. The Company is in the process of evaluating whether the adoption of this standard will have a material effect on its financial position, results of operations or cash flows.

The Company operates on a global basis and is exposed to the risk that its earnings, cash flows and stockholders’ equity could be adversely impacted by fluctuations in currency exchange rates and interest rates. The Company attempts to minimize its exposures by using certain financial instruments, for purposes other than trading, in accordance with the Company’s overall risk management guidelines.

The Company is primarily exposed to currency exchange-rate risk with respect to certain inter-company balances, forecasted transactions and cash flow, and net assets denominated in Euro, Japanese Yen, British Pound and Singapore Dollar. The Company manages its foreign currency exposures on a consolidated basis, which allows the Company to analyze exposures globally and take into account offsetting exposures in certain balances. In addition, the Company utilizes derivative and non-derivative financial instruments to further reduce the net exposure to currency fluctuations.

The Company is also exposed to the risk that its earnings and cash flows could be adversely impacted by fluctuations in interest rates. The Company’s policy is to manage interest costs by using a mix of fixed and floating rate debt that management believes is appropriate. At times, to manage this mix in a cost efficient manner, the Company has periodically entered into interest rate swaps in which the Company agrees to exchange, at specified intervals, the difference between fixed and floating interest amounts calculated by reference to an agreed upon notional amount.

Hedge Transactions

The Company records its hedge transactions in accordance the accounting standard for derivative instruments and hedging activities, which establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities. All derivatives, whether designated in hedging relationships or not, are required to be recorded on the consolidated balance sheets at fair value as either assets or liabilities. If the derivative is designated as a fair-value hedge, the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are recognized in earnings. If the derivative is designated as a cash flow hedge, the effective portions of changes in the fair value of the derivative are recorded in other comprehensive income and are recognized in earnings when the hedged item affects earnings; ineffective portions of changes in fair value are recognized in earnings. In addition, disclosures required for derivative instruments and hedging activities include the Company’s objectives for using derivative instruments, the level of derivative activity the Company engages in, as well as how derivative instruments and related hedged items affect the Company’s financial position and performance.

The Company currently uses derivative instruments to manage exposures to foreign currency and interest rate risks. The Company’s objectives for holding derivatives are to minimize foreign currency and interest rate risk using the most effective methods to eliminate or reduce the impact of foreign currency and interest rate exposures. The Company documents all relationships between hedging instruments and hedged items and links all derivatives designated as fair-value, cash flow or net investment hedges to specific assets and liabilities on the consolidated

balance sheets or to specific forecasted transactions. In addition, the Company considers the impact of its counterparties’ credit risk on the fair value of the contracts as well as the ability of each party to execute under the contracts. The Company also assesses and documents, both at the hedges’ inception and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in fair values or cash flows associated with the hedged items.

Cash Flow Hedges

The Company uses interest rate swap agreements to hedge the risk to earnings associated with fluctuations in interest rates related to outstanding U.S. dollar floating rate debt. In August 2007, the Company entered into two floating-to-fixed-rate interest rate swaps, each with a notional amount of $50 million and maturity dates of April 2009 and October 2009, to hedge floating rate debt related to the term loan facility of its outstanding debt. At December 31, 2009, the Company had no outstanding interest rate swap agreements. At both December 31, 2008 and 2007, the Company had a $2 million liability in other current liabilities in the consolidated balances sheets related to the interest rate swap agreements. For the year ended December 31, 2009, the Company recorded a change of $2 million in accumulated other comprehensive income on these interest rate swap agreements. For the years ended December 31, 2008 and 2007, the Company recorded a cumulative net pre-tax unrealized loss of $1 million and $2 million in accumulated other comprehensive income, respectively, on these interest rate swap agreements. For the years ended December 31, 2009, 2008 and 2007, the Company recorded additional interest expense of $2 million, $1 million and less than $1 million, respectively.

Hedges of Net Investments in Foreign Operations

The Company has operations in various countries and currencies throughout the world, with approximately 33% of its sales denominated in Euros, 11% in Japanese Yen and smaller sales exposures in other currencies in 2009. As a result, the Company’s financial position, results of operations and cash flows can be affected by fluctuations in foreign currency exchange rates. The Company uses cross-currency interest rate swaps, forward contracts and range forward contracts to hedge its stockholders’ equity balance from the effects of fluctuations in currency exchange rates. These agreements are designated as foreign currency hedges of a net investment in foreign operations. Any increase or decrease in the fair value of cross-currency interest rate swap agreements, forward contracts or range forward contracts is offset by the change in the value of the hedged net assets of the Company’s consolidated foreign affiliates. Therefore, these derivative instruments are intended to serve as an effective hedge of certain foreign net assets of the Company.

During 2007, the Company hedged its net investment in Euro foreign affiliates with cross-currency interest rate swaps, with notional values ranging from $20 million to $50 million. At December 31, 2009, 2008 and 2007, the Company had no outstanding cross-currency interest rate swap contracts. For the year ended December 31, 2007, the Company recorded cumulative net pre-tax losses of $10 million in accumulated other comprehensive income, which consists of realized losses of $10 million.

Other

The Company enters into forward foreign exchange contracts, principally to hedge the impact of currency fluctuations on certain inter-company balances and short-term assets and liabilities. Principal hedged currencies include the Euro, Japanese Yen, British Pound and Singapore Dollar. The periods of these forward contracts typically range from one to three months and have varying notional amounts which are intended to be consistent with changes in the underlying exposures. Gains and losses on these forward contracts are recorded in selling and administrative expenses in the consolidated statements of operations. At December 31, 2009, 2008 and 2007, the Company held forward foreign exchange contracts with notional amounts totaling approximately $138 million, $120 million and $101 million, respectively. At December 31, 2009 and 2008, the Company had liabilities of less than $1 million and $2 million, respectively, in other current liabilities in the consolidated balance sheets related to the foreign currency exchange contracts. At December 31, 2007, the Company had assets of less than $1 million in other current assets in the consolidated balance sheets related to the foreign currency exchange contracts. For the year ended December 31, 2009, the Company recorded cumulative net pre-tax gains of $7 million, which consists of realized gains of $5 million relating to the closed forward contracts and $2 million of unrealized gains relating to the open forward contracts. For the year ended December 31, 2008, the Company recorded cumulative net pre-tax

losses of $23 million, which consists of realized losses of $22 million relating to the closed forward contracts and $1 million of unrealized losses relating to the open forward contracts. For the year ended December 31, 2007, the Company recorded cumulative net pre-tax gains of $2 million, which consists of realized gains of $3 million relating to the closed forward contracts and $1 million of unrealized losses relating to the open forward contracts.

Assuming a hypothetical adverse change of 10% in year-end exchange rates (a strengthening of the U.S. dollar), the fair market value of the forward contracts outstanding as of December 31, 2009 would decrease pre-tax earnings by approximately $14 million.

The Company is exposed to the risk of interest rate fluctuations from the investments of cash generated from operations. The Company’s cash equivalents represent highly liquid investments, with original maturities of generally 90 days or less, in bank deposits; U.S., German, French and Dutch Government Treasury Bills; AAA rated U.S. Treasury Bills and European government bond money market funds. Similar investments with longer maturities are classified as short-term investments. Cash equivalents and short-term investments are convertible to a known amount of cash and carry an insignificant risk of change in market value. The Company maintains balances in various operating accounts in excess of federally insured limits, and in foreign subsidiary accounts in currencies other than U.S. dollars. As of December 31, 2009, the Company has no holdings in auction rate securities or commercial paper issued by structured investment vehicles, collateralized debt obligation conduits or asset-backed conduits.

The Company’s cash, cash equivalents and short-term investments are not subject to significant interest rate risk due to the short maturities of these instruments. As of December 31, 2009, the carrying value of the Company’s cash and cash equivalents approximated fair value.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-15(f) or 15d-15(f) under the Exchange Act. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, we conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation under the framework in Internal Control — Integrated Framework, our management, including our chief executive officer and chief financial officer, concluded that our internal control over financial reporting was effective as of December 31, 2009.

The effectiveness of our internal control over financial reporting as of December 31, 2009 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which is included herein.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of Waters Corporation

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of operations, of stockholders’ equity and comprehensive income, and of cash flows present fairly, in all material respects, the financial position of Waters Corporation and its subsidiaries at December 31, 2009 and December 31, 2008 and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2009 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2009, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express opinions on these financial statements and on the Company’s internal control over financial reporting based on our integrated 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 audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

As discussed in Notes 6 and 9 to the consolidated financial statements, respectively, the Company changed the manner in which it accounts for business combinations effective January 1, 2009 and uncertain tax positions effective January 1, 2007.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) 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 (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

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

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Waters Corporation (“Waters” or the “Company”), an analytical instrument manufacturer, primarily designs, manufactures, sells and services, through its Waters Division, high performance liquid chromatography (“HPLC”), ultra performance liquid chromatography (“UPLC^®” and together with HPLC, referred to as “LC”) and mass spectrometry (“MS”) instrument systems and support products, including chromatography columns, other consumable products and comprehensive post-warranty service plans. These systems are complementary products that can be integrated together and used along with other analytical instruments. LC is a standard technique and is utilized in a broad range of industries to detect, identify, monitor and measure the chemical, physical and biological composition of materials, and to purify a full range of compounds. MS instruments are used in drug discovery and development, including clinical trial testing, the analysis of proteins in disease processes (known as “proteomics”), food safety analysis and environmental testing. LC is often combined with MS to create LC-MS instruments that include a liquid phase sample introduction and separation system with mass spectrometric compound identification and quantification. Through its TA Division (“TA^®”), the Company primarily designs, manufactures, sells and services thermal analysis, rheometry and calorimetry instruments, which are used in predicting the suitability of fine chemicals, polymers and viscous liquids for various industrial, consumer goods and healthcare products, as well as for life science research. The Company is also a developer and supplier of software-based products that interface with the Company’s instruments and are typically purchased by customers as part of the instrument system.

Use of Estimates

The preparation of consolidated financial statements in conformity with generally accepted accounting principles (“GAAP”) requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent liabilities. On an ongoing basis, the Company evaluates its estimates, including those related to revenue recognition, product returns and allowances, bad debts, inventory valuation, equity investments, goodwill and intangible assets, warranty and installation provisions, income taxes, contingencies, litigation, retirement plan obligations and stock-based compensation. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual amounts may differ from these estimates under different assumptions or conditions.

Risks and Uncertainties

The Company is subject to risks common to companies in the analytical instrument industry, including, but not limited to, global economic and financial market conditions, development by its competitors of new technological innovations, risk of disruption, fluctuations in foreign currency exchange rates, dependence on key personnel, protection and litigation of proprietary technology, compliance with regulations of the U.S. Food and Drug Administration and similar foreign regulatory authorities and agencies and changes in the fair value of the underlying assets of the Company’s defined benefit plans.

Reclassifications

Certain amounts from prior years have been reclassified in the accompanying financial statements in order to be consistent with the current year’s classifications.

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and its subsidiaries, most of which are wholly owned. The Company consolidates entities in which it owns or controls fifty percent or more of the voting shares. All material inter-company balances and transactions have been eliminated.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Translation of Foreign Currencies

For most of the Company’s foreign operations, assets and liabilities are translated into U.S. dollars at exchange rates prevailing on the balance sheet date, while revenues and expenses are translated at average exchange rates prevailing during the period. Any resulting translation gains or losses are included in accumulated other comprehensive income in the consolidated balance sheets. The Company’s net sales derived from operations outside the United States were 69% in 2009, 70% in 2008 and 68% in 2007. Gains and losses from foreign currency transactions are included in net income in the consolidated statements of operations and were not material for the years presented.

Cash and Cash Equivalents

Cash equivalents primarily represent highly liquid investments, with original maturities of generally 90 days or less, in bank deposits; U.S., German, French and Dutch Government Treasury Bills; AAA rated U.S. Treasury Bills and European government bond money market funds, which are convertible to a known amount of cash and carry an insignificant risk of change in market value. Similar investments with longer maturities are classified as short-term investments. The Company maintains balances in various operating accounts in excess of federally insured limits, and in foreign subsidiary accounts in currencies other than U.S. dollars.

Short-Term Investments

Short-term investments are classified as available-for-sale in accordance with the accounting standard for investments in debt and equity securities. All available-for-sale securities are recorded at fair market value and any unrealized holding gains and losses, to the extent deemed temporary, are included in accumulated other comprehensive income in stockholders’ equity, net of the related tax effects. Realized gains and losses are determined on the specific identification method and are included in other income (expense) net. If any adjustment to fair value reflects a decline in the value of the investment, the Company considers all available evidence to evaluate the extent to which the decline is “other than temporary” and marks the investment to market through a charge to the statement of operations. The Company classifies its investments as short-term investments exclusive of those categorized as cash equivalents. At December 31, 2009, the Company had short-term investments with a cost of $289 million, which approximated market value. The Company had no short-term investments as of December 31, 2008.

Concentration of Credit Risk

The Company sells its products and services to a significant number of large and small customers throughout the world, with net sales to the pharmaceutical industry of approximately 51% in 2009, 50% in 2008 and 52% in 2007. None of the Company’s individual customers accounted for more than 3% of annual Company sales in 2009, 2008 or 2007. The Company performs continuing credit evaluations of its customers and generally does not require collateral, but in certain circumstances may require letters of credit or deposits. Historically, the Company has not experienced significant bad debt losses.

Seasonality of Business

The Company experiences an increase in sales in the fourth quarter, as a result of purchasing habits for capital goods of customers that tend to exhaust their spending budgets by calendar year end.

Accounts Receivable and Allowance for Doubtful Accounts

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts is the best estimate of the amount of probable credit losses in the existing accounts receivable. The allowance is based on a number of factors, including historical experience and the customer’s credit-worthiness. The allowance for doubtful accounts is reviewed on at least a quarterly basis. Past due balances over 90 days and over a specified amount are reviewed individually for collectibility. Account balances are charged against the

allowance when the Company feels it is probable that the receivable will not be recovered. The Company does not have any off-balance sheet credit exposure related to its customers.

The following is a summary of the activity of the Company’s allowance for doubtful accounts and sales returns for the years ended December 31, 2009, 2008 and 2007 (in thousands):

Allowance for Doubtful Accounts and Sales Returns:

2009

2008

2007

Inventory

The Company values all of its inventories at the lower of cost or market on a first-in, first-out basis (“FIFO”).

Deferred income taxes are recognized for temporary differences between the financial statement and income tax basis of assets and liabilities using tax rates in effect for the years in which the differences are expected to reverse. A valuation allowance is provided to offset any net deferred tax assets if, based upon the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. A liability has also been recorded to recognize uncertain tax return reporting positions.

Property, Plant and Equipment

Property, plant and equipment are recorded at cost. Expenditures for maintenance and repairs are charged to expense, while the costs of significant improvements are capitalized. Depreciation is provided using the straight-line method over the following estimated useful lives: buildings — fifteen to thirty years; building improvements — five to ten years; leasehold improvements — the shorter of the economic useful life or life of lease; and production and other equipment — three to ten years. Upon retirement or sale, the cost of the assets disposed of and the related accumulated depreciation are eliminated from the consolidated balance sheets and related gains or losses are reflected in the consolidated statements of operations. There were no material gains or losses from retirement or sale of assets in 2009, 2008 and 2007.

Goodwill and Other Intangible Assets

The Company tests for goodwill impairment using a fair-value approach at the reporting unit level annually, or earlier, if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. Additionally, the Company has elected to make January 1 the annual impairment assessment date for its reporting units. The goodwill and other intangible assets accounting standard defines a reporting unit as an operating segment, or one level below an operating segment, if discrete financial information is prepared and reviewed by management. Goodwill is allocated to the reporting units at the time of acquisition. Under the impairment test, if a reporting unit’s carrying amount exceeds its estimated fair value, goodwill impairment is recognized to the extent that the carrying amount of goodwill exceeds the implied fair value of the goodwill. The fair value of reporting units was estimated using a discounted cash flows technique, which includes certain management assumptions, such as estimated future cash flows, estimated growth rates and discount rates.

The Company’s intangible assets include purchased technology; capitalized software development costs; costs associated with acquiring Company patents, trademarks and intellectual properties, such as licenses; debt issuance costs and acquired in-process research and development (“IPR&D”). Purchased intangibles are recorded at their fair

market values as of the acquisition date and amortized over their estimated useful lives, ranging from one to fifteen years. Other intangibles are amortized over a period ranging from one to thirteen years. Debt issuance costs are amortized over the life of the related debt. Acquired IPR&D is amortized from the date of completion over its estimated useful life. In addition, acquired IPR&D will be tested for impairment until completion of the acquired programs.

Software Development Costs

The Company capitalizes software development costs for products offered for sale in accordance with the accounting standard for the costs of software to be sold, leased, or otherwise marketed. Capitalized costs are amortized to cost of sales over the period of economic benefit, which approximates a straight-line basis over the estimated useful lives of the related software products, generally three to five years.

The Company capitalizes internal software development costs in accordance with the accounting standard for goodwill and other intangible assets. Capitalized internal software development costs are amortized over the period of economic benefit which approximates a straight-line basis over ten years. Net capitalized internal software included in property, plant and equipment totaled $2 million at December 31, 2009 and 2008.

Investments

The Company accounts for its investments that represent less than twenty percent ownership, and for which the Company does not have significant influence, using the accounting standard for investments in debt and equity securities. Investments for which the Company does not have the ability to exercise significant influence, and for which there is not a readily determinable market value, are accounted for under the cost method of accounting. The Company periodically evaluates the carrying value of its investments accounted for under the cost method of accounting and carries them at the lower of cost or estimated net realizable value. For investments in which the Company owns or controls between twenty and forty-nine percent of the voting shares, or over which it exerts significant influence over operating and financial policies, the equity method of accounting is used. The Company’s share of net income or losses of equity investments is included in the consolidated statements of operations and was not material in any period presented. All investments at December 31, 2009 and 2008 are included in other assets and amounted to $4 million and $7 million, respectively.

Asset Impairments

The Company reviews its long-lived assets for impairment in accordance with the accounting standard for property, plant and equipment. Whenever events or circumstances indicate that the carrying amount of an asset may not be recoverable, the Company evaluates the fair value of the asset, relying on a number of factors, including, but not limited to, operating results, business plans, economic projections and anticipated future cash flows. Any change in the carrying amount of an asset as a result of the Company’s evaluation is separately identified in the consolidated statements of operations.

Fair Values of Financial Instruments

In accordance with the accounting standards for fair value measurements and disclosures, the Company’s assets and liabilities are measured at fair value on a recurring basis as of December 31, 2009 and 2008. Fair values determined by Level 1 inputs utilize observable data such as quoted prices in active markets. Fair values determined by Level 2 inputs utilize data points other than quoted prices in active markets that are observable either directly or indirectly. Fair values determined by Level 3 inputs utilize unobservable data points in which there is little or no market data, which require the reporting entity to develop its own assumptions.

The following table represents the Company’s assets and liabilities measured at fair value on a recurring basis as of December 31, 2009 (in thousands):

Assets:

Cash equivalents

Short-term investments

Waters Retirement Restoration Plan assets

Foreign currency exchange contract agreements

Liabilities:

The following table represents the Company’s assets and liabilities measured at fair value on a recurring basis as of December 31, 2008 (in thousands):

Interest rate swap agreements

The Company’s financial assets and liabilities have been classified as Level 2. These assets and liabilities have been initially valued at the transaction price and subsequently valued typically utilizing third-party pricing services. The pricing services use many inputs to determine value, including reportable trades, benchmark yields, credit spreads, broker/dealer quotes, current spot rates and other industry and economic events. The Company validates the prices provided by third-party pricing services by reviewing their pricing methods and obtaining market values from other pricing sources. The fair values of the Company’s cash equivalents, short-term investments, retirement restoration plan assets, foreign currency exchange contracts and interest rate swap agreements are determined through market and observable sources and have been classified as Level 2. After completing these validation procedures, the Company did not adjust or override any fair value measurements provided by third-party pricing services as of December 31, 2009 and 2008.

In January 2009, the Company implemented the accounting and disclosure requirements related to non-financial assets and liabilities that are remeasured at fair value on a non-recurring basis. The adoption of this accounting and disclosure requirement did not have a significant impact on the Company’s financial statements.

Stockholders’ Equity

In February 2007, the Company’s Board of Directors authorized the Company to repurchase up to $500 million of its outstanding common stock over a two-year period. During 2009, 2008 and 2007, the Company repurchased a total of 8.2 million shares at a cost of $454 million under this program, which expired in February 2009.

The Company repurchased 4.5 million, 4.1 million and 3.4 million shares at a cost of $210 million, $235 million and $201 million during 2009, 2008 and 2007, respectively, under the February 2009 authorization and previously announced programs. The Company believes it has the resources to fund the common stock repurchases as well as to pursue acquisition opportunities in the future.

On August 9, 2002, the Board of Directors approved the adoption of a stock purchase rights plan where a dividend of one fractional preferred share purchase right (a “Right”) was declared for each outstanding share of common stock, par value $0.01 per share, of the Company. The dividend was paid on August 27, 2002 to the stockholders of record on that date. The Rights, which expire on August 27, 2012, become exercisable only under certain conditions. When they first become exercisable, each Right will entitle its holder to buy from Waters one one-hundredth of a share of new Series A Junior Participating Preferred Stock (authorized limit of 4,000) for $120.00. When a person or group actually has acquired 15% or more of Waters’ common stock, the Rights will then become exercisable for a number of shares of Waters’ common stock with a market value of twice the $120.00 exercise price of each Right. In addition, the Rights will then become exercisable for a number of shares of common stock of the acquiring company with a market value of twice the $120.00 exercise price per Right. The Board of Directors may redeem the Rights at a price of $0.001 per Right up until 10 days following a public announcement that any person or group has acquired 15% or more of the Company’s common stock.

The Company records its hedge transactions in accordance with the accounting standard for derivative instruments and hedging activities, which establishes accounting and reporting standards for derivative instruments, including certain derivative instruments embedded in other contracts, and for hedging activities. All derivatives, whether designated in hedging relationships or not, are required to be recorded on the consolidated balance sheets at fair value as either assets or liabilities. If the derivative is designated as a fair-value hedge, the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are recognized in earnings. If the derivative is designated as a cash flow hedge, the effective portions of changes in the fair value of the derivative are recorded in other comprehensive income and are recognized in earnings when the hedged item affects earnings; ineffective portions of changes in fair value are recognized in earnings. In addition, disclosures required for derivative instruments and hedging activities include the Company’s objectives for using derivative instruments, the level of derivative activity the Company engages in, as well as how derivative instruments and related hedged items affect the Company’s financial position and performance.

designated as fair-value, cash flow or net investment hedges to specific assets and liabilities on the consolidated balance sheets or to specific forecasted transactions. In addition, the Company considers the impact of its counterparties’ credit risk on the fair value of the contracts as well as the ability of each party to execute under the contracts. The Company also assesses and documents, both at the hedges’ inception and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in fair values or cash flows associated with the hedged items.

other current assets in the consolidated balance sheets related to the foreign currency exchange contracts. For the year ended December 31, 2009, the Company recorded cumulative net pre-tax gains of $7 million, which consists of realized gains of $5 million relating to the closed forward contracts and $2 million of unrealized gains relating to the open forward contracts. For the year ended December 31, 2008, the Company recorded cumulative net pre-tax losses of $23 million, which consists of realized losses of $22 million relating to the closed forward contracts and $1 million of unrealized losses relating to the open forward contracts. For the year ended December 31, 2007, the Company recorded cumulative net pre-tax gains of $2 million, which consists of realized gains of $3 million relating to the closed forward contracts and $1 million of unrealized losses relating to the open forward contracts.

Product shipments, including those for demonstration or evaluation, and service contracts are not recorded as revenues until a valid purchase order or master agreement is received specifying fixed terms and prices. The Company’s method of revenue recognition for certain products requiring installation is in accordance with accounting standards for revenue recognition. Accordingly, revenue is recognized when all of the following criteria are met: persuasive evidence of an arrangement exists; delivery has occurred; the vendor’s fee is fixed or determinable; collectibility is reasonably assured and, if applicable, upon acceptance when acceptance criteria with contractual cash holdback are specified. With respect to installation obligations, the larger of the contractual cash holdback or the fair value of the installation service is deferred when the product is shipped and revenue is recognized as a multiple-element arrangement when installation is complete. The Company determines the fair value of installation based upon a number of factors, including hourly service billing rates, estimated installation hours and comparisons of amounts charged by third parties.

The Company recognizes product revenue when legal title has transferred and risk of loss passes to the customer. The Company structures its sales arrangements as FOB shipping point or international equivalent and, accordingly, recognizes revenue upon shipment. In some cases, FOB destination based shipping terms are included in sales arrangements, in which cases revenue is recognized when the products arrive at the customer site.

Returns and customer credits are infrequent and are recorded as a reduction to sales. Rights of return are not included in sales arrangements. Revenue associated with products that contain specific customer acceptance criteria is not recognized before the customer acceptance criteria are satisfied. Discounts from list prices are recorded as a reduction to sales.

Sales of software are accounted for in accordance with the accounting standards for software revenue recognition. Software revenue is recognized upon shipment, as typically no significant post-delivery obligations remain. Software upgrades are typically sold as part of a service contract with revenue recognized ratably over the term of the service contract.

The Company assists customers in obtaining financing with an independent third-party leasing company with respect to certain product sales. Revenue is generally recognized upon product shipment under these arrangements. The Company receives payment from the leasing company shortly after shipment, provided delivery and credit documentation meets contractual criteria. The customer is obligated to pay the leasing company, but the Company retains some credit risk if the customer is unable to pay. Accordingly, the Company reduces revenue equal to pre-established loss-pool criteria, including contracts with recourse. The Company’s credit risk is significantly reduced through loss-pool limitations and re-marketing rights in the event of a default.

Product Warranty Costs

The Company accrues estimated product warranty costs at the time of sale, which are included in cost of sales in the consolidated statements of operations. While the Company engages in extensive product quality programs and processes, including actively monitoring and evaluating the quality of its component supplies, the Company’s warranty obligation is affected by product failure rates, material usage and service delivery costs incurred in correcting a product failure. The amount of the accrued warranty liability is based on historical information, such as past experience, product failure rates, number of units repaired and estimated costs of material and labor. The liability is reviewed for reasonableness at least quarterly.

The following is a summary of the activity of the Company’s accrued warranty liability for the years ended December 31, 2009, 2008 and 2007 (in thousands):

Accrued warranty liability:

Advertising Costs

All advertising costs are expensed as incurred and are included in selling and administrative expenses in the consolidated statements of operations. Advertising expenses for 2009, 2008 and 2007 were $10 million, $9 million and $6 million, respectively.

Research and development expenses are comprised of costs incurred in performing research and development activities, including salaries and benefits, facilities costs, overhead costs, contract services and other outside costs. Research and development expenses are expensed as incurred.

Stock-Based Compensation

The Company has two stock-based compensation plans, which are described in Note 12, “Stock-Based Compensation”.

Earnings Per Share

In accordance with the earnings per share accounting standard, the Company presents two earnings per share (“EPS”) amounts. Income per basic common share is based on income available to common shareholders and the weighted-average number of common shares outstanding during the periods presented. Income per diluted common share includes additional dilution from potential common stock, such as stock issuable pursuant to the exercise of stock options outstanding.

Comprehensive Income

The Company accounts for comprehensive income in accordance with the accounting standards for comprehensive income, which establishes the accounting rules for reporting and displaying comprehensive income and its components in a full set of general-purpose financial statements. The standard requires that all components of comprehensive income be reported in a financial statement that is displayed with the same prominence as other financial statements.

The adoption of this standard will not have a material effect on its financial position, results of operations or cash flows.

In October 2009, a new accounting consensus was issued for multiple-deliverable revenue arrangements. This consensus amends existing revenue recognition accounting standards. This consensus provides accounting principles and application guidance on whether multiple deliverables exist, how the arrangement should be separated and the consideration allocated. This guidance eliminates the requirement to establish the fair value of undelivered products and services and instead provides for separate revenue recognition based upon management’s estimate of the selling price for an undelivered item when there is no other means to determine the fair value of that undelivered item. Previously the existing accounting consensus required that the fair value of the undelivered item be the price of the item either sold in a separate transaction between unrelated third parties or the price charged for each item when the item is sold separately by the vendor. Under the existing accounting consensus, if the fair value of all of the elements in the arrangement was not determinable, then revenue was deferred until all of the items were delivered or fair value was determined. This new approach is effective prospectively for revenue arrangements entered into or materially modified in fiscal years beginning on or after June 15, 2010. The Company is in the process of evaluating whether the adoption of this standard will have a material effect on its financial position, results of operations or cash flows.

During 2008, the Company identified errors originating in periods prior to the three months ended June 28, 2008. The errors primarily related to (i) an overstatement of the Company’s income tax expense of $16 million as a result of errors in recording its income tax provision during the period from 2000 to March 29, 2008 and (ii) an understatement of amortization expense of $9 million for certain capitalized software. The Company incorrectly calculated its provision for income taxes by tax-effecting its tax liability utilizing a U.S. tax rate of 35% instead of an Irish tax rate of approximately 10%. In addition, the Company incorrectly accounted for Irish-based capitalized software and the related amortization expense as U.S. Dollar-denominated instead of Euro-denominated, resulting in an understatement of amortization expense and cumulative translation adjustment.

The Company identified and corrected the errors in the three months ended June 28, 2008, which had the effect of increasing cost of sales by $9 million; reducing gross profit and income from operations before income tax by $9 million; reducing the provision for income taxes by $16 million and increasing net income by $8 million. For the year ended December 31, 2008, the errors had the effect of reducing the Company’s effective tax rate by 4.0 percentage points. In addition, the out-of-period adjustments had the following effect on the consolidated balance sheet as of June 28, 2008: increased the gross carrying value of capitalized software by $46 million; increased accumulated amortization for capitalized software by $36 million; reduced deferred tax liabilities by $14 million and increased accumulated other comprehensive income by $17 million.

The Company did not believe that the prior period errors, individually or in the aggregate, were material to any previously issued annual or quarterly financial statements. In addition, the Company did not believe that the adjustments described above to correct the cumulative effect of the errors in the three months ended June 28, 2008 were material to the three months ended June 28, 2008 or to the full year results for 2008. As a result, the Company did not restate its previously issued annual financial statements or interim financial data.

Inventories are classified as follows (in thousands):

During 2009, 2008 and 2007, the Company retired and disposed of approximately $7 million, $9 million and $4 million of property, plant and equipment, respectively, most of which was fully depreciated and no longer in use. Gains and losses on disposal were immaterial.

Effective January 1, 2009, the Company implemented the newly issued accounting standard for business combinations. This standard requires an acquiring company to measure all assets acquired and liabilities assumed, including contingent considerations and all contractual contingencies, at fair value as of the acquisition date. In addition, an acquiring company is required to capitalize IPR&D and either amortize it over the life of the product or write it off if the project is abandoned or impaired. This accounting standard is applicable to acquisitions completed after January 1, 2009. Previous standards generally required post-acquisition adjustments related to business combination deferred tax asset valuation allowances and liabilities for uncertain tax positions to be recorded as an increase or decrease to goodwill. This new accounting standard does not permit this accounting and generally requires any such changes to be recorded in current period income tax expense. Thus, all changes to valuation allowances and liabilities for uncertain tax positions established in acquisition accounting, whether the business combination was accounted for under previous standards or under the newly issued accounting standard, will be recognized in current period income tax expense.

In February 2009, the Company acquired all of the remaining outstanding capital stock of Thar Instruments, Inc. (“Thar”), a privately-held global leader in the design, development and manufacture of analytical and preparative supercritical fluid chromatography and supercritical fluid extraction (“SFC”) systems, for $36 million in cash, including the assumption of $4 million of debt. Thar was acquired to add its environmentally-friendly SFC technology to the Company’s product line and to leverage the Company’s distribution channels. The Company had previously made a $4 million equity investment in Thar in June 2007. Immediately prior to the acquisition date, the Company remeasured the fair value of its original equity investment in Thar, resulting in an acquisition date fair

value of $4 million. Thus, there was no gain or loss recognized in the statement of operations as a result of remeasuring the Company’s equity interest in Thar to fair value prior to the business combination.

The acquisition of Thar was accounted for under the newly issued accounting standard for business combinations and the results of Thar have been included in the consolidated results of the Company from the acquisition date. The purchase price of the acquisition was allocated to tangible and intangible assets and assumed liabilities based on their estimated fair values. The Company has allocated $24 million of the purchase price to intangible assets comprised of customer relationships, non-compete agreements, acquired technology, IPR&D and other purchased intangibles. The Company is amortizing the customer relationships and acquired technology over 15 years. The non-compete agreements and other purchased intangibles are being amortized over five years. These intangible assets are being amortized over a weighted-average period of 13 years. Included in intangible assets is a trademark in the amount of $4 million, which has been assigned an indefinite life. Also included in intangible assets are IPR&D intangibles in the amount of $1 million, which will be amortized over an estimated useful life of 15 years once the projects have been completed and commercialized. The excess purchase price of $22 million has been accounted for as goodwill. The sellers also have provided the Company with customary representations, warranties and indemnification, which would be settled in the future if and when the contractual representation or warranty condition occurs. The goodwill is not deductible for tax purposes. Since the acquisition date, Thar added $17 million of sales to the consolidated statements of operations for the year ended December 31, 2009. Thar’s impact on the Company’s net income since the acquisition date for the year ended December 31, 2009 was not significant.

In accordance with the accounting standards for fair value measurements and disclosures, the Company measured the non-financial assets and non-financial liabilities that were acquired through the acquisition of Thar at fair value. The fair value of these non-financial assets and non-financial liabilities were determined using Level 3 inputs. The following table presents the fair values, as determined by the Company, of 100% of the assets and liabilities owned and recorded in connection with the Thar acquisition (in thousands):

In December 2008, the Company acquired the net assets of Analytical Products Group, Inc. (“APG”), a provider of environmental testing products for quality control and proficiency testing used in environmental laboratories, for $5 million in cash. This acquisition was accounted for under the purchase method of accounting and the results of APG have been included in the consolidated results of the Company from the acquisition date. The purchase price of the acquisition was allocated to tangible and intangible assets and assumed liabilities based on their estimated fair values. The Company has allocated $3 million of the purchase price to intangible assets comprised of non-compete agreements, acquired technology, customer relationships and tradename. These intangible assets are being amortized over a weighted-average period of ten years. The excess purchase price of $1 million after this allocation has been accounted for as goodwill. The goodwill is deductible for tax purposes.

In July 2008, the Company acquired the net assets of VTI Corporation (“VTI”), a manufacturer of sorption analysis and thermogravimetric analysis instruments, for $3 million in cash. This acquisition was accounted for under the purchase method of accounting and the results of VTI have been included in the consolidated results of the

Company from the acquisition date. The purchase price of the acquisition was allocated to tangible and intangible assets and assumed liabilities based on their estimated fair values. The Company has allocated $1 million of the purchase price to intangible assets comprised of a non-compete agreement and acquired technology. These intangible assets are being amortized over a weighted-average period of nine years. The excess purchase price of $2 million after this allocation has been accounted for as goodwill. The goodwill is deductible for tax purposes.

In October 2007, the Company acquired certain net assets and customer lists from a South Korean distributor of thermal analysis products for a total of $2 million in cash. This acquisition was accounted for under the purchase method of accounting and the results of operations have been included in the consolidated results of the Company from the acquisition date.

In August 2007, the Company acquired all of the outstanding capital stock of Calorimetry Sciences Corporation (“CSC”), a privately-held company that designs, develops and manufactures highly sensitive calorimeters, for $7 million in cash, including the assumption of $1 million of liabilities. This acquisition was accounted for under the purchase method of accounting and the results of operations of CSC have been included in the consolidated results of the Company from the acquisition date.

The pro forma effect of the ongoing operations for Waters, Thar, APG, VTI, CSC and other acquisitions as though these acquisitions had occurred at the beginning of the periods covered by this report is immaterial.

The carrying amount of goodwill was $293 million, $268 million and $273 million at December 31, 2009, 2008 and 2007, respectively. The increase in goodwill in 2009 is primarily due to the Company’s acquisition of Thar, which increased goodwill by $22 million (Note 6). In addition, currency translation adjustments increased goodwill by $3 million in 2009. The decrease in goodwill in 2008 is attributable to an $8 million decrease due to currency translation being partially offset by the $3 million of goodwill from the Company’s acquisitions of VTI and APG.

The Company’s intangible assets included in the consolidated balance sheets are detailed as follows (in thousands):

Purchased intangibles

Capitalized software

Licenses

Patents and other intangibles

During the year ended December 31, 2009, the Company acquired $24 million of purchased intangibles as a result of the acquisition of Thar. During 2008, the gross carrying value of capitalized software and related accumulated amortization increased by $46 million and $36 million, respectively, primarily as a result of an out-of-period adjustment (Note 3). During the year ended December 31, 2008, the Company acquired $4 million of purchased intangibles as a result of the acquisitions of VTI and APG. In addition, the gross carrying value of intangible assets increased by $4 million in 2009 and decreased by $25 million in 2008 due to the effect of foreign currency translation. The gross carrying value of accumulated amortization for intangible assets increased by $3 million in 2009 and decreased by $17 million in 2008 due to the effect of foreign currency translation.

For the years ended December 31, 2009, 2008 and 2007, amortization expense for intangible assets was $25 million, $36 million and $26 million, respectively. Included in amortization expense for the year ended December 31, 2008 is a $9 million out-of-period adjustment related to capitalized software. Amortization expense for intangible assets is estimated to be approximately $30 million for each of the next five years.

In February 2010, the Company issued and sold five-year senior unsecured notes at an interest rate of 3.75% with a face value of $100 million. This debt matures in February 2015. The Company plans to use the proceeds from the issuance of these senior unsecured notes to repay other outstanding debt amounts and for general corporate purposes. Interest on both issuances of the senior unsecured notes are payable semi-annually in February and August of each year. The Company may redeem some or all of the notes at any time in an amount not less than 10% of the aggregate principal amount outstanding, plus accrued and unpaid interest, plus the applicable make-whole amount. These notes require that the Company comply with an interest coverage ratio test of not less than 3.50:1 and a leverage ratio test of not more than 3.50:1 for any period of four consecutive fiscal quarters, respectively. In addition, these notes include negative covenants that are similar to the existing credit agreement. These notes also contain certain customary representations and warranties, affirmative covenants and events of default.

In March 2008, the Company entered into a new credit agreement (the “2008 Credit Agreement”) that provided for a $150 million term loan facility. In January 2007, the Company entered into a credit agreement (the “2007 Credit Agreement”) that provides for a $500 million term loan facility and $600 million in revolving facilities, which include both a letter of credit and a swingline subfacility. Both credit agreements were to mature on January 11, 2012 and required or require no scheduled prepayments before that date. The outstanding portions of the revolving facilities have been classified as short-term liabilities in the consolidated balance sheets due to the fact that the Company utilizes the revolving line of credit to fund its working capital needs. It is the Company’s intention to pay the outstanding revolving line of credit balance during the subsequent twelve months following the respective period end date.

In October 2008, the Company utilized cash balances associated with the effective liquidation of certain foreign legal entities into the U.S. to voluntarily prepay the $150 million term loan under the 2008 Credit Agreement. The Company prepaid the term loan in order to reduce interest expense and there was no penalty for prepaying the term loan. The repayment of the term loan effectively terminated all lending arrangements under the 2008 Credit Agreement.

As of December 31, 2009, the Company had a total of $620 million borrowed under the 2007 Credit Agreement and an amount available to borrow of $479 million after outstanding letters of credit. At December 31, 2009, $500 million of the total debt was classified as long-term debt and $120 million classified as short-term debt in the consolidated balance sheet. As of December 31, 2008, the Company had $500 million borrowed under the 2007 Credit Agreement and an amount available to borrow of $599 million after outstanding letters of credit. At December 31, 2008, $500 million of the total debt was classified as long-term debt in the consolidated balance sheet. The weighted-average interest rates applicable to these borrowings were 0.78% and 2.43% at December 31, 2009 and 2008, respectively.

The Company and its foreign subsidiaries also had available short-term lines of credit totaling $88 million at both December 31, 2009 and 2008. At December 31, 2009 and 2008, related short-term borrowings were $12 million at a weighted-average interest rate of 1.97% and $36 million at a weighted-average interest rate of 2.18%, respectively.

Net deferred tax assets

Net deferred tax assets of $21 million and $30 million are included in other current assets and $19 million and $46 million are included in other assets at December 31, 2009 and 2008, respectively.

The Company’s deferred tax assets associated with net operating loss, tax credit carryforwards and alternative minimum tax credits are comprised of the following at December 31, 2009: less than $1 million benefit of U.S. federal and state net operating loss carryforwards that begin to expire in 2020 and 2010, respectively; $71 million in foreign tax credits, which begin to expire in 2010; $11 million in research and development credits that begin to expire in 2010; and $1 million ($3 million pre-tax) in foreign net operating losses, $1 million ($2 million pre-tax) of which do not expire under current law, the remainder of which begin to expire in 2010. The Company has excluded the benefit of $14 million ($38 million pre-tax) of U.S. federal and state net operating loss carryforwards from the deferred tax asset balance at December 31, 2009. This amount represents an “excess tax benefit”, as the term is defined in the accounting standard for stock-based compensation, which will be recognized as a reduction to the Company’s accrued income taxes and an addition to its additional paid-in capital when it is realized in the Company’s tax returns.

As of December 31, 2009, the Company has provided a deferred tax valuation allowance of $84 million, principally against foreign tax credits ($71 million), certain foreign net operating losses and other deferred tax assets. The benefit relating to foreign tax credits and these other deferred tax assets, if realized, will be credited to additional paid-in capital.

The income tax benefits associated with non-qualified stock option compensation expense recognized for tax purposes and credited to additional paid-in capital were $5 million, $7 million and $17 million for the years ended December 31, 2009, 2008 and 2007, respectively.

At December 31, 2009, there were unremitted earnings of foreign subsidiaries of approximately $1.4 billion. The Company has not provided for U.S. income taxes or foreign withholding taxes on these earnings as it is the Company’s current intention to permanently reinvest these earnings outside the U.S.

Effective on January 1, 2007, the Company adopted a new accounting interpretation standard relating to income taxes which prescribed the methodology by which a company must measure, report, present and disclose in its financial statements the effects of any uncertain tax return reporting positions that a company has taken or expects to take. This accounting standard requires financial statement reporting of the expected future tax consequences of uncertain tax return reporting positions on the presumption that all relevant tax authorities possess full knowledge of those tax reporting positions, as well as all of the pertinent facts and circumstances, but it prohibits any discounting of any of the related tax effects for the time value of money. This standard also mandates expanded financial statement disclosure about uncertainty in income tax reporting positions. The Company recorded the effect of adopting this standard with a $4 million charge to beginning retained earnings in the consolidated balance sheet as of January 1, 2007.

The following is a summary of the activity in the Company’s unrecognized tax benefits for the years ended December 31, 2009, 2008 and 2007 (in thousands):

Balance at the beginning of the period

Change in tax positions of the current year

Balance at the end of the period

For the years ended December 31, 2009 and 2008, the Company recorded increases of $1 million and $9 million, respectively, in unrecognized tax benefits via the income tax provision. In 2009, the Company recorded approximately $5 million of tax benefit relating to the reversal of a $5 million tax provision which was originally recorded in 2008 relating to the reorganization of certain foreign legal entities. The recognition of this tax benefit in 2009 was a result of changes in income tax regulations promulgated by the U.S. Treasury in February 2009. If all of the Company’s unrecognized tax benefits accrued as of December 31, 2009 were to become recognizable in the future, the Company would record a total reduction of approximately $78 million in the income tax provision.

The Company’s accounting policy is to record estimated interest and penalties related to the potential underpayment of income taxes, net of related tax effects, as a component of the income tax provision. For each of the years ended December 31, 2009, 2008 and 2007, the Company included $1 million ($2 million pre-tax) of such interest expense, net of related tax benefits, and no income tax penalty expense in the income tax provision. As of December 31, 2009 and 2008, the Company had accrued $7 million ($10 million pre-tax) and $5 million ($8 million pre-tax), respectively, of such estimated interest expense, net of related tax benefits. As of both December 31, 2009 and 2008, the Company had no income tax penalty expense accrued.

The Company’s uncertain tax positions are taken with respect to income tax return reporting periods beginning after December 31, 1999, which are the periods that generally remain open to income tax audit examination by the various income tax authorities. As of December 31, 2009, the Company expects that a tax audit of one of the Company’s U.K. affiliates’ tax returns for 2003, 2004 and 2005 will be settled before December 31, 2010. As of December 31, 2009, the Company does not expect the settlement of that audit to have a material effect on its consolidated financial statements. In addition, the Company has monitored and will continue to monitor the lapsing of statutes of limitations on potential tax assessments for related changes in the measurement of unrecognized tax benefits, related net interest and penalties, and deferred tax assets and liabilities. Other than the aforementioned tax audit, as of December 31, 2009, the Company does not expect to record any material changes in the measurement of unrecognized tax benefits, related net interest and penalties or deferred tax assets and liabilities due to the settlement of tax audit examinations or to the lapsing of statutes of limitations on potential tax assessments within the next twelve months.

The Company’s effective tax rates for years ended December 31, 2009, 2008 and 2007 were 16.4%, 13.4% and 17.1%, respectively. Included in the income tax provision for 2009 is approximately $5 million of tax benefit relating to the reversal of a $5 million provision which was originally recorded in 2008 relating to the reorganization of certain foreign legal entities. The recognition of this tax benefit in 2009 was a result of changes in income tax regulations promulgated by the U.S. Treasury in February 2009. The $5 million tax benefit decreased the Company’s effective tax rate by 1.2 percentage points in 2009. The one-time provision increased the Company’s effective tax rate by 1.4 percentage points in 2008. In addition, the effective tax rate for 2008 included a $16 million benefit resulting from out-of-period adjustments related to software capitalization amortization. The out-of-period adjustments had the effect of reducing the Company’s effective tax rate by 4.0 percentage points in 2008. The 2007 tax provision includes a $4 million tax benefit associated with a one-time contribution into the Waters Employee Investment Plan. The remaining changes in the effective tax rates for 2009, 2008 and 2007 are primarily attributable to changes in income in jurisdictions with different effective tax rates.

The Company is involved in various litigation matters arising in the ordinary course of business. The Company believes the outcome, if the plaintiff ultimately prevails, will not have a material impact on the Company’s financial position.

The Company has been engaged in ongoing patent litigation with Agilent Technologies GmbH in France and Germany. In January 2009, the French appeals court affirmed that the Company had infringed the Agilent Technologies GmbH patent and a judgment was issued against the Company. The Company has appealed this judgment. In 2008, the Company recorded a $7 million provision and, in the first quarter of 2009, the Company made a payment of $6 million for damages and fees estimated to be incurred in connection with the French litigation case. The accrued patent litigation expense is in other current liabilities in the consolidated balance sheets at December 31, 2009 and 2008. No provision has been made for the German patent litigation and the Company believes the outcome, if the plaintiff ultimately prevails, will not have a material impact on the Company’s financial position.

Lease agreements, expiring at various dates through 2026, cover buildings, office equipment and automobiles. Rental expense was $34 million, $30 million and $23 million during the years ended December 31, 2009, 2008 and 2007, respectively. Future minimum rents payable as of December 31, 2009 under non-cancelable leases with initial terms exceeding one year are as follows (in thousands):

The Company licenses certain technology and software from third parties, which expire at various dates through 2010. Fees paid for licenses were less than $1 million for each of the years ended December 31, 2009, 2008 and 2007. Future minimum license fees payable under existing license agreements as of December 31, 2009 are immaterial for the years ended December 31, 2010 and thereafter.

The Company enters into standard indemnification agreements in its ordinary course of business. Pursuant to these agreements, the Company indemnifies, holds harmless and agrees to reimburse the indemnified party for

losses suffered or incurred by the indemnified party, generally the Company’s business partners or customers, in connection with patent, copyright or other intellectual property infringement claims by any third party with respect to its current products, as well as claims relating to property damage or personal injury resulting from the performance of services by the Company or its subcontractors. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited. Historically, the Company’s costs to defend lawsuits or settle claims relating to such indemnity agreements have been minimal and management accordingly believes the estimated fair value of these agreements is immaterial.

In May 2003, the Company’s shareholders approved the Company’s 2003 Equity Incentive Plan (“2003 Plan”). As of December 31, 2009, the 2003 Plan has 3.0 million shares available for granting in the form of incentive or non-qualified stock options, stock appreciation rights (“SARs”), restricted stock, restricted stock units or other types of awards. The Company issues new shares of common stock upon exercise of stock options or restricted stock unit conversion. Under the 2003 Plan, the exercise price for stock options may not be less than the fair market value of the underlying stock at the date of grant. The 2003 Plan is scheduled to terminate on March 4, 2013. Options generally will expire no later than 10 years after the date on which they are granted and will become exercisable as directed by the Compensation Committee of the Board of Directors and generally vest in equal annual installments over a five-year period. A SAR may be granted alone or in conjunction with an option or other award. Shares of restricted stock and restricted stock units may be issued under the 2003 Plan for such consideration as is determined by the Compensation Committee of the Board of Directors. No award of restricted stock may have a restriction period of less than three years except as may be recommended by the Compensation Committee of the Board of Directors, or with respect to any award of restricted stock which provides solely for a performance-based risk of forfeiture so long as such award has a restriction period of at least one year. As of December 31, 2009, the Company had stock options, restricted stock and restricted stock unit awards outstanding.

In February 2009, the Company adopted its 2009 Employee Stock Purchase Plan under which eligible employees may contribute up to 15% of their earnings toward the quarterly purchase of the Company’s common stock. The plan makes available 0.9 million shares of the Company’s common stock, which includes the remaining shares available under the 1996 Employee Stock Purchase Plan. As of December 31, 2009, 0.9 million shares have been issued under both the 2009 and 1996 Employee Stock Purchase Plans. Each plan period lasts three months beginning on January 1, April 1, July 1 and October 1 of each year. The purchase price for each share of stock is the lesser of 90% of the market price on the first day of the plan period or 100% of the market price on the last day of the plan period. Stock-based compensation expense related to this plan was $1 million, $1 million and less than $1 million for each of the years ended December 31, 2009, 2008 and 2007.

The Company accounts for stock-based compensation costs in accordance with the accounting standards for stock-based compensation, which requires that all share-based payments to employees be recognized in the statements of operations based on their fair values. The Company recognizes the expense using the straight-line attribution method. The stock-based compensation expense recognized in the consolidated statements of operations is based on awards that ultimately are expected to vest; therefore, the amount of expense has been reduced for estimated forfeitures. This accounting standard requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Forfeitures were estimated based on historical experience. If actual results differ significantly from these estimates, stock-based compensation expense and the Company’s results of operations could be materially impacted. In addition, if the Company employs different assumptions in the application of this accounting standard, the compensation expense that the Company records in the future periods may differ significantly from what the Company has recorded in the current period.

The consolidated statements of operations for the years ended December 31, 2009, 2008 and 2007 include the following stock-based compensation expense related to stock option awards, restricted stock, restricted stock unit awards and the employee stock purchase plan (in thousands):

Cost of sales

Total stock-based compensation

As of both December 31, 2009 and 2008, the Company has capitalized stock-based compensation costs of less than $1 million in inventory in the consolidated balance sheets. As of December 31, 2009 and 2008, the Company has capitalized stock-based compensation costs of $3 million and $2 million, respectively, in capitalized software in the consolidated balance sheets.

Stock Option Plans

In determining the fair value of the stock options, the Company makes a variety of assumptions and estimates, including volatility measures, expected yields and expected stock option lives. The fair value of each option grant was estimated on the date of grant using the Black-Scholes option pricing model. The Company uses implied volatility on its publicly traded options as the basis for its estimate of expected volatility. The Company believes that implied volatility is the most appropriate indicator of expected volatility because it is generally reflective of historical volatility and expectations of how future volatility will differ from historical volatility. The expected life assumption for grants is based on historical experience for the population of non-qualified stock optionees. The risk-free interest rate is the yield currently available on U.S. Treasury zero-coupon issues with a remaining term approximating the expected term used as the input to the Black-Scholes model. The relevant data used to determine the value of the stock options granted in 2009, 2008 and 2007 are as follows:

The total cash received from the exercise of these stock options was $16 million, $25 million and $89 million for the years ended December 31, 2009, 2008 and 2007, respectively.

As of December 31, 2009, 2008 and 2007, there were $36 million, $41 million and $51 million of total unrecognized compensation costs related to unvested stock option awards. These costs are expected to be recognized over a weighted-average period of 3.4 years.

Restricted Stock

During each of the years ended December 31, 2009, 2008 and 2007, the Company granted eight thousand shares of restricted stock. The restrictions on these shares lapse at the end of a three-year period. The Company has recorded less than $1 million of compensation expense in each of the years ended December 31, 2009, 2008 and 2007 related to the restricted stock grants. The weighted-average fair value on the grant date of the restricted stock for 2009, 2008 and 2007 was $38.09, $76.75 and $48.88, respectively. As of December 31, 2009, the Company has 24 thousand unvested shares of restricted stock outstanding with a total of less than $1 million of unrecognized compensation costs. These costs are expected to be recognized over a weighted-average period of 1.5 years.

U.S. employees are eligible to participate in the Waters Employee Investment Plan, a 401(k) defined contribution plan, after one month of service. Employees may contribute from 1% to 30% of eligible pay on a pre-tax basis. Prior to the amendments described below, which became effective on January 1, 2008, the Company made matching contributions of 50% for contributions up to 6% of eligible pay after one year of service. Employees are 100% vested in employee and Company matching contributions. For the years ended December 31, 2009, 2008 and 2007, the Company’s matching contributions amounted to $10 million, $10 million and $4 million, respectively.

U.S. employees were eligible to participate in the Waters Retirement Plan, a defined benefit, cash balance plan, after one year of service. Annually, the Company credited each employee’s account as a percentage of eligible pay based on years of service. In addition, each employee’s account is credited with interest at the end of each year based

on the employee’s account balance at the beginning of such year. The interest rate is the one-year constant maturity Treasury bond yield in effect as of the first business day in November preceding such year plus 0.5%, limited to a minimum interest crediting rate of 5% and a maximum interest crediting rate of 10%. An employee does not vest until the completion of three years of service, at which time the employee becomes 100% vested. The Company maintains an unfunded supplemental executive retirement plan, the Waters Retirement Restoration Plan, which is non-qualified and restores the benefits under the Waters Retirement Plan that are limited by IRS benefit and compensation maximums.

In September 2007, the Company’s Board of Directors approved various amendments to freeze the pay credit accruals under the Waters Retirement Plan and the Waters Retirement Restoration Plan (collectively, the “U.S. Pension Plans”) effective December 31, 2007. In accordance with accounting standards for retirement benefits, the Company recorded a curtailment gain of $1 million. In addition, the Company re-measured the U.S. Pension Plans’ liabilities in September 2007 and the Company reduced the projected benefit obligation liability by $7 million with a corresponding adjustment, net of tax, to accumulated other comprehensive income as a result of the curtailment reducing the accrual for future service.

The Company’s Board of Directors also approved a $13 million payment that was contributed to the Waters Employee Investment Plan in the first quarter of 2008. The $13 million of expense was reduced by a curtailment gain of $1 million, relating to various amendments to freeze the pay credit accrual, resulting in $12 million of expense recorded in the consolidated statements of operations in the year ending December 31, 2007 with $3 million included in cost of sales, $7 million included in selling and administrative expenses and $2 million included in research and development expenses. In addition, effective January 1, 2008, the Company’s Board of Directors increased the employer matching contribution in the Waters Employee Investment Plan to 100% for contributions up to 6% of eligible pay, an increase of 3%, and eliminated the one-year service requirement to be eligible for matching contributions.

The Company also sponsors other employee benefit plans in the U.S., including a retiree healthcare plan, which provides reimbursement for medical expenses and is contributory. There are various non-U.S. retirement plans sponsored by the Company. The eligibility and vesting of the non-U.S. plans are generally consistent with local laws and regulations.

The net periodic pension cost is made up of several components that reflect different aspects of the Company’s financial arrangements as well as the cost of benefits earned by employees. These components are determined using the projected unit credit actuarial cost method and are based on certain actuarial assumptions. The Company’s accounting policy is to reflect in the projected benefit obligation all benefit changes to which the Company is committed as of the current valuation date; use a market-related value of assets to determine pension expense; amortize increases in prior service costs on a straight-line basis over the expected future service of active participants as of the date such costs are first recognized; and amortize cumulative actuarial gains and losses in excess of 10% of the larger of the market-related value of plan assets and the projected benefit obligation over the expected future service of active participants.

Summary data for the U.S. Pension Plans, the U.S. retiree healthcare plan and the Company’s non-U.S. retirement plans are presented in the following tables, using the measurement dates of December 31, 2009 and 2008, respectively.

Within the equity portfolio of the U.S. retirement plans, investments are diversified among market capitalization and investment strategy. The Company targets a 20% allocation of its U.S. retirement plans’ equity portfolio to be invested in financial markets outside of the United States. The Company does not invest in its own stock within the U.S. retirement plans’ assets.

The weighted-average assumptions used to determine the benefit obligation in the consolidated balance sheets at December 31, 2009, 2008 and 2007 are as follows:

Discount rate

Increases in compensation levels

The weighted-average assumptions used to determine the pension cost at December 31, 2009, 2008 and 2007 are as follows:

Return on assets

To develop the expected long-term rate of return on assets assumption, the Company considered the historical returns and the future expectations for returns for each asset class, as well as the target asset allocation of the pension portfolio and historical expenses paid by the plan. A one-quarter percentage point increase in the discount rate would decrease the Company’s net periodic benefit cost for the Waters Retirement Plan by less than $1 million. A one-quarter percentage point increase in the assumed long-term rate of return would decrease the Company’s net periodic benefit cost for the Waters Retirement Plan by less than $1 million.

During fiscal year 2010, the Company expects to contribute approximately $3 million to $5 million to the Company’s defined benefit plans.

Estimated future benefit payments as of December 31, 2009 are as follows (in thousands):

The accounting standard for segment reporting establishes standards for reporting information about operating segments in annual financial statements and requires selected information for those segments to be presented in interim financial reports of public business enterprises. It also establishes standards for related disclosures about products and services, geographic areas and major customers. The Company’s business activities, for which financial information is available, are regularly reviewed and evaluated by the chief operating decision makers. As a result of this evaluation, the Company determined that it has two operating segments: Waters Division and TA Division.

Waters Division is primarily in the business of designing, manufacturing, distributing and servicing LC and MS instruments, columns and other chemistry consumables that can be integrated and used along with other analytical instruments. TA Division is primarily in the business of designing, manufacturing, distributing and servicing thermal analysis, rheometry and calorimetry instruments. The Company’s two divisions are its operating segments and each has similar economic characteristics; product processes; products and services; types and classes of customers; methods of distribution and regulatory environments. Because of these similarities, the two segments have been aggregated into one reporting segment for financial statement purposes. Please refer to the consolidated financial statements for financial information regarding the one reportable segment of the Company.

The Company experiences an increase in sales in the fourth quarter, as a result of purchasing habits on capital goods of customers that tend to exhaust their spending budgets by calendar year end. Selling and administrative expenses are typically higher in the second and third quarters over the first quarter in each year as the Company’s annual payroll merit increases take effect. Selling and administrative expenses will vary in the fourth quarter in relation to performance in the quarter and for the year. In the first quarter of 2009, the Company recorded approximately $5 million of tax benefit relating to the reversal of a $5 million tax provision which was originally recorded in the third quarter of 2008 relating to the reorganization of certain foreign legal entities (Note 9). In the second quarter of 2008, the Company recorded out-of-period adjustments related to capitalized software amortization and the income tax provision (Note 3). In the fourth quarter of 2008, the Company recorded a $7 million provision related to ongoing litigation (Note 10).
