Foundry Park I. The TEL business of Ethyl is reflected in the “All other” category. All of these are discussed below.

Petroleum Additives—Petroleum additives are used in lubricating oils and fuels to enhance their performance in machinery, vehicles, and other equipment. We manufacture chemical components that are selected to perform one or more specific functions and combine those chemicals with other components to form additive packages for use in specified end-user applications. The petroleum additives market is an international marketplace, with customers ranging from oil companies and refineries to original equipment manufacturers (OEMs) and other specialty chemical companies. The products offered by the petroleum additives segment are sold to common customers, are served by the same plants, share common components or building blocks, and are supported with a common sales, as well as research and development, workforce.

We believe our success in the petroleum additives market is largely due to our ability to bring value to our customers through our products and our open, flexible, and collaborative working style. We accomplish this by understanding their needs and applying our technical capabilities, formulation expertise, broadly differentiated product offerings, and global distribution capabilities to meet those needs. We invest significantly in research and development in order to meet our customers’ needs, and to adapt to the rapidly changing environment for new and improved products and services.

We view the petroleum additives marketplace as being comprised of two broad product groupings: lubricant additives and fuel additives. Lubricant additives are highly formulated chemical products that improve the efficiency, durability, performance, and functionality of mineral oils, synthetic oils, and biodegradable fluids, thereby enhancing the performance of machinery and engines. Fuel additives are chemical components and products that improve the refining process and performance of gasoline, diesel, biofuels, and other fuels, resulting in lower fuel costs, improved vehicle performance, reduced tailpipe or smokestack emissions, and improved power plant efficiency.

Lubricant Additives

Lubricant additives are essential ingredients for lubricating oils. Lubricant additives are used in a wide variety of vehicle and industrial applications, including engine oils, transmission fluids, gear oils, hydraulic oils, turbine oils, and in virtually any other application where metal-to-metal moving parts are utilized. Lubricant additives are organic and synthetic chemical components that enhance wear protection, prevent deposits, and protect against the hostile operating environment of an engine, transmission, axle, hydraulic pump, or industrial machine.

Lubricants are used in nearly every piece of operating machinery from heavy industrial equipment to vehicles. Lubricants provide a layer of protection between moving mechanical parts. Without this layer of protection, the normal functioning of machinery would not occur. Effective lubricants reduce downtime, prevent accidents, and increase efficiency. Specifically, lubricants serve the following main functions:

• Friction reduction—Friction is reduced by maintaining a thin film of lubricant between moving surfaces, preventing them from coming into direct contact with one another and reducing wear on moving machinery.

• Heat removal—Lubricants act as coolants by removing heat resulting from either friction or through contact with other, higher temperature materials.

• Containment of contaminants—Lubricants can be contaminated in many ways, especially over time. Lubricants are required to function by carrying contaminants away from the machinery and neutralizing the deleterious impact of the by-products of combustion.

4

The functionality of lubricants is created through an exact balance between a base fluid and performance enhancing additives. This balance is the goal of effective formulations achieved by experienced research professionals. We offer a full line of lubricant additive products, each of which is composed of component chemicals specially selected to perform desired functions. We manufacture most of the chemical components and blend these components to create formulated additives packages designed to meet industry and customer specifications. Lubricant additive components are generally classified based upon their intended functionality, including:

• detergents, which clean moving parts of engines and machines, suspend oil contaminants and combustion by-products, and absorb acidic combustion products;

• dispersants, which serve to inhibit the formation of sludge and particulates;

• extreme pressure/antiwear agents, which reduce wear on moving engine and machinery parts;

• viscosity index modifiers, which improve the viscosity and temperature characteristics of lubricants and help the lubricant flow evenly to all parts of an engine or machine; and

• antioxidants, which prevent oil from degrading over time.

We are one of the leading global suppliers of specially formulated lubricant additives that combine some or all of the components described above to develop our products. Our products are highly formulated, complex chemical compositions derived from extensive research and testing to ensure all additive components work together to provide the intended results. Our products are engineered to meet specifications prescribed by either the industry generally or a specific customer. Purchasers of lubricant additives tend to be oil companies, distributors, refineries, and compounders/blenders.

Key drivers of demand for lubricant additives include total vehicle miles driven, vehicle production, equipment production, the average age of vehicles on the road, new engine and driveline technologies, and drain/refill intervals.

We view our participation in the lubricant marketplace in three primary areas: engine oil additives, driveline additives, and industrial additives. Our view is not necessarily the same way others view the market.

Engine Oil Additives—The largest submarket within the lubricant additives marketplace is engine oil additives, which we estimate represents approximately 70% of the overall lubricant additives market volume. The engine oils market’s primary customers include consumers, service dealers, and OEMs. The extension of drain intervals has generally offset increased demand due to higher vehicle population and more miles driven. The primary functions of engine oil additives are to reduce friction, prevent wear, control formation of sludge and oxidation, and prevent rust. Engine oil additives are typically sold to lubricant manufacturers who combine them with a base oil fluid to meet internal, industry, and OEM specifications.

Key drivers of the engine oils market are the number of vehicles on the road, drain intervals for engine oils, engine and crankcase size, changes in engine design, and temperature and specification changes driven by the OEMs. Afton offers additives for oils that protect the modern engine and makes additives that are specially formulated to protect high mileage vehicles. Afton offers products that enhance the performance of mineral, part-synthetic, and fully-synthetic engine oils.

Driveline Additives—The driveline additives submarket is comprised of additives designed for products such as transmission fluids (TF), gear oils, and off-road fluids. This submarket shares in the 30% of the market not covered by engine oils. TF primarily serve as the power transmission and heat transfer medium in the area of the transmission where the torque of the drive shaft is transferred to the gears of the vehicle. Gear oil additives lubricate gears, bearings, clutches, and bands in the gear-box and are used in vehicles, off-highway, hydraulic, and marine equipment. Other products in this area include hydraulic transmission fluids, universal tractor fluids,

5

power steering fluids, shock absorber fluids, gear oils, lubricants for heavy machinery, and vehicle greases. These products must conform to highly prescribed specifications developed by vehicle OEMs for specific models or designs. These additives are generally sold to oil companies and often ultimately sold to vehicle OEMs for new vehicles (factory-fill). End-products are also sold to service dealers for aftermarket servicing (service-fill), as well as retailers and distributors.

Key drivers of the driveline additives marketplace are the number of vehicles manufactured, drain intervals for TF and gear applications, changes in engine and transmission design and temperatures, and specification changes driven by the OEMs.

Industrial Additives—The industrial additives submarket is comprised of additives designed for products for industrial applications such as hydraulic fluids, grease, industrial gear fluids, industrial specialty applications, and metalworking additives. This submarket also shares in the 30% of the market not covered by engine oils. These products must conform to industry specifications, OEM requirements and/or application and operating environment demands. Industrial additives are generally sold to oil companies, service dealers for after-market servicing, and distributors.

Key drivers of the industrial additives marketplace are gross domestic product levels and industrial production.

Fuel Additives

Fuel additives are chemical compounds that are used to improve both the oil refining process and the performance of gasoline, diesel, residual, biofuels, and other fuels. Benefits of fuel additives in the oil refining process include reduced use of crude oil, lower processing costs, and improved fuel storage properties. Fuel performance benefits include ignition improvements, combustion efficiency, reduced emission particulates, fuel economy improvements, and engine cleanliness, as well as protection against deposits in fuel injectors, intake valves, and the combustion chamber. Our fuel additives are extensively tested and designed to meet stringent industry, government, OEM, and individual customer requirements.

Many different types of additives are used in fuels. Their use is generally determined by customer, industry, OEM, and government specifications, and often differs from country to country. The types of fuel additives we offer include:

• gasoline performance additives, which clean and maintain key elements of the fuel delivery systems, including fuel injectors and intake valves, in gasoline engines;

• diesel fuel performance additives, which perform similar cleaning functions in diesel engines;

• cetane improvers, which increase the cetane number (ignition quality) in diesel fuel by reducing the delay between injection and ignition;

• stabilizers, which reduce or eliminate oxidation in fuel;

• corrosion inhibitors, which minimize the corrosive effects of combustion by-products and prevent rust;

• lubricity additives, which restore lubricating properties lost in the refining process;

• cold flow improvers, which improve the pumping and flow of diesel in cold temperatures; and

• octane enhancers, which increase octane ratings and decrease emissions.

We offer a broad line of fuel additives worldwide and sell our products to major fuel marketers and refiners, as well as independent terminals and other fuel blenders.

Key drivers in the fuel additive marketplace include total vehicle miles driven, the introduction of more sophisticated engines, regulations on emissions (both gasoline and diesel), quality of the crude oil slate and performance standards, and marketing programs of major oil companies.

Competition

We believe we are one of the four largest manufacturers and suppliers in the petroleum additives marketplace.

In the lubricant additives submarket of petroleum additives, our major competitors are The Lubrizol Corporation, Infineum (a joint venture between ExxonMobil Chemical and Royal Dutch Shell plc), and Chevron Oronite Company LLC. There are several other suppliers in the worldwide market who are competitors in their particular product areas.

The fuel additives submarket is fragmented and characterized by many competitors. While we participate in many facets of the fuel additives market, our competitors tend to be more narrowly focused. In the gasoline detergent market, we compete mainly against BASF AG, Chevron Oronite Company LLC, and The Lubrizol Corporation; in the cetane improver market, we compete mainly against Innospec, Inc. (Innospec), Eurenco, and EPC - U.K.; and in the diesel markets, we compete mainly against The Lubrizol Corporation, Infineum, BASF AG, and Innospec. We also compete against other regional competitors in the fuel additives marketplace.

The competition among the participants in these industries is characterized by the need to provide customers with cost effective, technologically-capable products that meet or exceed industry specifications. The need to continually increase technology performance and lower cost through formulation technology and cost improvement programs is vital for success in this environment.

Real Estate Development—The real estate development segment represents the operations of Foundry Park I.

In January 2007, Foundry Park I entered into a Deed of Lease Agreement with MeadWestvaco Corporation (MeadWestvaco) under which it is leasing an office building which we have constructed on approximately three acres. The construction of the building was completed in late 2009 and was to the specifications of MeadWestvaco, which is using the building as its corporate headquarters. The rental income to us began in 2010. The lease term is for a period of 13 ¹/2 years with rent based upon a factor of the final project cost.

Foundry Park I obtained financing, which was due in August 2010 and which was guaranteed by NewMarket Corporation, for the construction phase. In early 2010, we secured a five year loan on the property. We used the proceeds from this loan together with cash on hand to repay the construction loan. Further information on our financing of the project and the related interest rate swap agreements is in Notes 12 and 16 (when we make a reference to Notes, we mean the Notes to Consolidated Financial Statements included herein). None of these agreements impacts the terms of the lease with MeadWestvaco. During 2007, 2008, and 2009, we capitalized the costs of the project, as well as the financing expenses.

We are currently exploring various development opportunities for other portions of the property we own, as the demand warrants. This search is ongoing in nature, as we have no specific timeline for any future developments.

All Other—The “All other” category includes the continuing operations of the TEL business (primarily sales of TEL in North America), as well as certain contract manufacturing Ethyl provides to Afton and to third parties. Ethyl manufacturing facilities include our Houston, Texas and Sarnia, Ontario, Canada plants. Both the Houston and Sarnia plants manufacture a significant amount of petroleum additives products for Afton. The Houston plant is substantially dedicated to petroleum additives manufacturing and produces both lubricant additives and fuel additives. The Sarnia plant is completely dedicated to petroleum additives manufacturing and produces fuel additives. The financial results of the petroleum additives production by the Ethyl manufacturing facilities are reflected in the petroleum additives segment results. The “All other” category financial results include a service fee charged by Ethyl for its production services to Afton. Our remaining manufacturing facilities are part of Afton and produce both lubricant additives and fuel additives.

Raw Materials and Product Supply

We use a variety of raw materials and chemicals in our manufacturing and blending processes and believe the sources of these are adequate for our current operations. The primary raw materials for Afton are base oil, polyisobutylene, antioxidants, alcohols, solvents, sulfonates, friction modifiers, olefins, and copolymers.

As the performance requirements of our products become more complex, we often work with highly specialized suppliers. In some cases, we source from a single supplier. In cases where we decide to source from a single supplier, we manage our risk by maintaining safety stock of the raw material, qualifying alternate supply, or identifying a backup position. The backup position could take additional time to implement, but we are confident we can ensure continued supply for our customers. We continue to monitor the raw material supply situation and will adjust our procurement strategies as conditions require.

Research, Development, and Testing

Research, development, and testing (R&D) provides technologies and performance based solutions for the petroleum additives market. We develop products through a combination of chemical synthesis, formulation, engineering design and performance testing. In addition to products, R&D provides our customers with product differentiation and technical support to assure total customer satisfaction.

We are committed to providing the most advanced products, comprehensive testing programs, creative solutions, and superior technical support to our customers and to OEMs worldwide. R&D expenditures, which totaled $91 million in 2010, $86 million in 2009, and $82 million in 2008, are expected to grow again in 2011 in support of our core technology areas. Afton continues to increase globally our internal testing, research, and customer support capabilities in support of our goals of providing market driven technical leadership and performance based differentiation.

In 2010, we successfully launched effective new technologies for multiple new engine oil categories including ILSAC GF-5, ACEA 2008, and General Motor’s new engine oil specification, dexos1™. Research in the engine oil area continues to increase with a focused approach to develop next generation technologies capable of meeting new performance standards and to provide our customers with marketing differentiation.

We continue to provide leading technology in the fuel additives area. New products were developed and launched in all product lines including gasoline performance additives, diesel performance additives and finished fuel additives. Research is focused on the development of new technologies that exceed the changing needs of modern engine fueling systems and changing fuel properties, as well as addressing the growing need for increased fuel economy and emissions reduction. In addition, we continued to maintain close interactions with regulatory, industry, and OEM leaders to guide our development of future fuel additive technologies based on well-defined market needs.

Our industrial additives product slate continued to expand with the development of new products in multiple areas including hydraulic fluids, grease, industrial gear oils, turbine oils, and metal working fluid additives. Research is focused on the development of technologies that will provide differentiation to our customers in multiple performance areas including equipment life and energy efficiency.

Technology development continued at a rapid pace in our driveline product lines. This included the development of new products, components, and technology for the expanding line-up of transmission types and the increasing need for fuel efficiency and performance durability in both transmission and axle systems. Afton’s state-of-the art testing capabilities are enabling customized research in all areas of performance needed by both OEMs and tier one suppliers. Our leading-edge capabilities and fundamental understanding in the areas of friction control, energy efficiency, and wear/pitting prevention were used to set the stage for next generation products in all driveline areas including both factory fill and service fill sectors.

Intellectual Property

Our intellectual property, including our patents, licenses, and trademarks, is an important component of our business. We actively protect our inventions, new technologies, and product developments by filing patent applications or maintaining trade secrets. We currently own approximately 1,400 issued or pending United States and foreign patents. In addition, we have acquired the rights under patents and inventions of others through licenses or otherwise. We take care to respect the intellectual property rights of others and we believe our products do not infringe upon those rights. We vigorously participate in patent opposition proceedings around the world, where necessary, to secure a technology base free of infringement. We believe our patent position is strong, aggressively managed, and sufficient for the conduct of our business.

We also have several hundred trademark registrations throughout the world for our marks, including NewMarket^®, Afton Chemical^®, Ethyl^®, mmt^®, HiTEC^®, TecGARD^®, GREENBURN^®, Passion for Solutions^®, CleanStart^®, Polartech^®, and BioTEC^®, as well as several pending trademark and service mark applications, including Axcel™ and 24/7 QuickResponse^SM.

Commitment to Environmental and Safety Excellence

We are committed to continuous improvement and vigilant management of the health and safety of our employees, customers, and the communities in which we operate, as well as the stewardship of the environment. One way our companies demonstrate this is through our commitment to the Guiding Principles of the American Chemistry Council (ACC) Responsible Care^® program. Both Afton and Ethyl have implemented Responsible Care Management Systems (RCMS^®) at their U.S. headquarters and most facilities. Our implementation of RCMS was certified by an independent auditing process as established by the ACC as a requirement of membership. Additionally, Afton’s Feluy, Belgium plant was certified to the environmental standard ISO 14001. Afton’s Sauget, Illinois plant also continues to be an OSHA Star VPP (Voluntary Protection Program) location.

Safety and environmental responsibility are a way of life at NewMarket—enhancing operations, the way we work, and the relationships we maintain with our employees, customers, supply chain partners, and the communities in which we operate. Our executive management meetings begin with a review of our environmental and safety performance.

Our objective is to establish a culture where our employees understand that good environmental and safety performance is good business and understand that environmental compliance and safety is their personal responsibility.

Our worldwide injury/illness recordable rate (which is the number of injuries per 200,000 hours worked) in 2010 was 0.64. The rate in 2009 was 0.66 and the 2008 rate was 0.84. We plan to continue to demonstrate our safety-first culture with continuous improvement in our safety record. This represents a focused effort by all of our employees. We are extremely proud of our accomplishments in the safety area, especially when compared to safety records in other industries.

As members of the ACC, Afton and Ethyl provide data on twelve metrics used to track environmental, safety, energy use, and product stewardship performance of ACC member companies. These can be viewed at www.responsiblecare-us.com. The information on this website is not, and shall not be deemed to be, a part of this Annual Report on Form 10-K or incorporated by reference in this Annual Report on Form 10-K or any other filings we make with the Securities and Exchange Commission (SEC).

Environmental

We operate under policies that we believe comply with federal, state, local, and foreign requirements regarding the handling, manufacture, and use of materials. One or more regulatory agencies may classify some of these materials as hazardous or toxic. We also believe that we comply in all material respects with laws, regulations,

9

statutes, and ordinances protecting the environment, including those related to the discharge of materials. We expect to continue to comply in all material respects.

We regularly review the status of significant existing or potential environmental issues. We record and expense our proportionate share of environmental remediation and monitoring costs in accordance with accounting principles generally accepted in the United States.

Total gross liabilities accrued at year-end for environmental remediation were $22.5 million for 2010 and $22.0 million for 2009. In addition to the accruals for environmental remediation, we also had accruals for dismantling and decommissioning costs of $500 thousand at both December 31, 2010 and December 31, 2009.

As new technology becomes available, it may be possible to reduce accrued amounts. While we believe that we are fully accrued for known environmental issues, it is possible that unexpected future costs could have a significant financial impact on our financial position and results of operations.

We spent approximately $18 million in 2010 and $17 million in both 2009 and 2008 for ongoing environmental operating and clean-up costs, excluding depreciation of previously capitalized expenditures. These environmental operating and clean-up expenses are included in cost of goods sold.

For capital expenditures on pollution prevention and safety projects, we spent $7 million in 2010, $5 million in 2009, and $7 million in 2008.

Our estimate of the effects of complying with governmental pollution prevention and safety regulations is subject to:

• potential changes in applicable statutes and regulations (or their enforcement and interpretation);

• uncertainty as to the success of anticipated solutions to pollution problems;

• uncertainty as to whether additional expense may prove necessary; and

• potential for emerging technology to affect remediation methods and reduce associated costs.

We are subject to liabilities associated with the investigation and cleanup of hazardous substances, as well as personal injury, property damage, or natural resource damage arising from the release of, or exposure to, such hazardous substances. Further, we may have environmental liabilities imposed in many situations without regard to violations of laws or regulations. These liabilities may also be imposed jointly and severally (so that a responsible party may be held liable for more than its share of the losses involved, or even the entire loss) and may be imposed on many different entities with a relationship to the hazardous substances at issue, including, for example, entities that formerly owned or operated the property and entities that arranged for the disposal of the hazardous substances at an affected property. We are subject to many environmental laws, including the federal Comprehensive Environmental Response, Compensation and Liability Act, commonly known as CERCLA or Superfund, in the United States, and similar foreign and state laws.

Under CERCLA, we are currently considered a potentially responsible party (PRP), at several sites, ranging from a de minimis PRP or a minor PRP, to an involvement considered greater than the minor PRP involvement. At some of these sites, the remediation methodology, as well as the proportionate shares of each PRP, has been well established. Other sites are not as mature, which makes it more difficult to reasonably estimate our share of the future clean-up or remediation costs.

In 2000, the Environmental Protection Agency (EPA) named us as a PRP for the clean-up of soil and groundwater contamination at the Sauget Area 2 Site in Sauget, Illinois. Without admitting any fact, responsibility, fault, or liability in connection with this site, we are participating with other PRPs in site investigations and feasibility studies. The Sauget Area 2 Site PRPs received notice of approval from the EPA of

10

their October 2009 Human Health Risk Assessment. Additionally, the PRPs have submitted their Feasibility Study (FS) to the EPA Remedy review board. We have accrued our estimated proportional share of the expenses for the FS, as well as our best estimate of our proportional share of the remediation liability proposed in our ongoing discussions and submissions with the agencies involved. We do not believe there is any additional information available as a basis for revision of the liability that we have established. The amount accrued for this site is not material. We also have several other sites where we are in the process of environmental remediation and monitoring. See Note 18.

Geographic Areas

We have operations in the United States, Europe, Asia, Latin America, Australia, India, the Middle East, and Canada. The economies are stable in the countries where we do most of our business. In countries with more political or economic uncertainty, we generally minimize our risk of loss by utilizing U.S. Dollar-denominated transactions, letters of credit, and prepaid transactions. Our foreign customers consist of financially viable government organizations, as well as both large and smaller companies.

The table below reports revenues and long-lived assets by geographic area. Except for the United States, no country exceeded 10% of revenue or long-lived assets during any year. We assign revenues to geographic areas based on the location to which the product was shipped to a third-party. The change in revenues during the three-year period is discussed more fully in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operation.”

ITEM 1A. RISK FACTORS

Our business is subject to many factors that could materially adversely affect our future performance and cause our actual results to differ materially from those expressed or implied by forward-looking statements made in this Annual Report on Form 10-K. Those risk factors are outlined below.

• Availability of raw materials and transportation systems, including sourcing from some single suppliers, could have a material adverse effect on our operations.

The chemical industry can experience some tightness of supply of certain materials or transportation systems. In addition, in some cases, we choose to source from a single supplier. Any significant disruption in supply could affect our ability to obtain raw materials or transportation systems. This could have a material adverse effect on our operations.

• Several of our products are produced solely at one facility, and a significant disruption or disaster at such a facility could have a material adverse effect on our results of operations.

Several of the products we sell are produced only in one location. We are dependent upon the continued safe operation of these production facilities. These production facilities are subject to various hazards associated with the manufacturing, handling, storage, and transportation of chemical materials and products, including leaks and ruptures, explosions, fires, inclement weather and natural disasters, unscheduled downtime, and environmental hazards. Some of our products involve the manufacturing and handling of a variety of reactive, explosive, and flammable materials. Many of these hazards could cause a disruption in the production of our products. We cannot assure you that these facilities will not experience these types of hazards and disruptions in the future or that these incidents will not result in production delays or otherwise have an adverse effect on our results of operations, financial condition or cash flows in any given period.

12

• We may be unable to respond effectively to technological changes in our industry.

Our future business success will depend upon our ability to maintain and enhance our technological capabilities, develop and market products and applications that meet changing customer needs, and successfully anticipate or respond to technological changes on a cost-effective and timely basis. Our industry is characterized by frequent changes in industry performance standards, which affect the amount and timing of our research and development costs and other technology-related costs. As a result, the life cycle of our products is often hard to predict. Further, technological changes in some or all of our customers’ products or processes may make our products obsolete. Our inability to maintain a highly qualified technical workforce or their inability to anticipate, respond to, or utilize changing technologies could have a material adverse effect on our results of operations, financial condition, and cash flow in any given period.

• Our failure to protect our intellectual property rights could adversely affect our future performance and growth.

Protection of our proprietary processes, methods, compounds, and other technologies is important to our business. We depend upon our ability to develop and protect our intellectual property rights to distinguish our products from those of our competitors. Failure to protect our existing intellectual property rights may result in the loss of valuable technologies or having to pay other companies for infringing on their intellectual property rights. We rely on a combination of patent, trade secret, trademark, and copyright law, as well as judicial enforcement, to protect such technologies. We currently own approximately 1,400 issued and pending U.S. and foreign patents. Some of these patents are licensed to others. In addition, we have acquired the rights under patents and inventions of others through licenses or otherwise. We have developed, and may in the future develop, technologies with universities or other academic institutions, or with the use of government funding. In such cases, the academic institution or the government may retain certain rights to the developed intellectual property. We also own several hundred trademark and service mark registrations throughout the world for our marks, including NewMarket^®, Afton Chemical^®, Ethyl^®, HiTEC^®, TecGARD^®, GREENBURN^® BioTEC^®, Passion for Solutions^®, CleanStart^®, Polartech^®, and mmt^®, as well as pending trademark and service mark applications, including Axcel™ and 24/7 QuickResponse^SM. In the event that we are unable to continue using certain of our marks, we may be forced to rebrand our products, which could result in the loss of brand recognition, and could require us to devote resources to advertise and market brands. In particular, the loss of our HiTEC^® mark would have a material adverse effect on our business.

We cannot assure you that the measures taken by us to protect these assets and rights will provide meaningful protection for our trade secrets or proprietary manufacturing expertise or that adequate remedies will be available in the event of an unauthorized use or disclosure of our trade secrets or manufacturing expertise. We cannot assure you that any of our intellectual property rights will not be challenged, invalidated, circumvented, or rendered unenforceable. Furthermore, we cannot assure you that any pending patent application filed by us will result in an issued patent, or if patents are issued to us, that those patents will provide meaningful protection against competitors or against competitive technologies. The failure of our patents or other measures to protect our processes, apparatuses, technology, trade secrets and proprietary manufacturing expertise, methods, and compounds could have an adverse effect on our results of operations, financial condition, and cash flow.

We could face patent infringement claims from our competitors or others alleging that our processes or products infringe on their proprietary technologies. If we were found to be infringing on the proprietary technology of others, we may be liable for damages, and we may be required to change our processes, to redesign our products partially or completely, to pay to use the technology of others or to stop using certain technologies or producing the infringing product entirely. Even if we ultimately prevail in an infringement suit, the existence of the suit could prompt customers to switch to products that are not the subject of infringement suits. We may not prevail in any intellectual property litigation and such litigation may result in significant legal costs or otherwise impede our ability to produce and distribute key products.

13

• Our business is subject to hazards common to chemical businesses, any of which could interrupt our production or our transportation systems and adversely affect our results of operations.

Our business is subject to hazards common to chemical manufacturing, storage, handling, and transportation, including explosions, fires, inclement weather, natural disasters, mechanical failure, unscheduled downtime, transportation interruptions, remediation, chemical spills, discharges or releases of toxic or hazardous substances or gases, and other risks. These hazards can cause personal injury and loss of life, severe damage to, or destruction of, property and equipment, and environmental contamination. In addition, the occurrence of material operating problems at our facilities due to any of these hazards may diminish our ability to meet our output goals. Accordingly, these hazards and their consequences could have a material adverse effect on our operations as a whole, including our results of operations, and cash flows, both during and after the period of operational difficulties.

• The occurrence or threat of extraordinary events, including natural disasters and domestic and international terrorist attacks may disrupt our operations, decrease demand for our products, and increase our expenses.

Chemical-related assets may be at greater risk of future terrorist attacks than other possible targets in the United States and throughout the world. Federal legislation has imposed significant new site security requirements, specifically on chemical manufacturing facilities, that will require an estimated $2 million to $3 million in capital expenditures over the next two years at our manufacturing facilities and increase our annual overhead expenses. Federal regulations have also been enacted to increase the security of the transportation of hazardous chemicals in the United States. Further regulations could be enacted in the future, which could result in additional costs.

The occurrence of extraordinary events, including future terrorist attacks and the outbreak or escalation of hostilities, cannot be predicted, but their occurrence can be expected to affect negatively the economy in general, and specifically the markets for our products. The resulting damage from a direct attack on our assets or assets used by us could include loss of life and property damage. In addition, available insurance coverage may not be sufficient to cover all of the damage incurred or, if available, may be prohibitively expensive.

• Competition could adversely affect our operating results.

We face intense competition in certain of the product lines and markets in which we compete. We expect that our competitors will develop and introduce new and enhanced products, which could cause a decline in the market acceptance of certain products we manufacture. In addition, as a result of price competition, we may be compelled to reduce the prices for some of our products, which could adversely affect our margins and profitability. Competitive pressures can also result in the loss of major customers. Our inability to compete successfully could have a material adverse effect on our results of operations, financial condition, and cash flows in any given period. In addition, some of our competitors may have greater financial, technological, and other resources than we have. Some of our competitors may also be able to maintain greater operating and financial flexibility than we are able to maintain. As a result, these competitors may be able to better withstand changes in conditions within our industry, changes in the prices for raw materials, and changes in general economic conditions.

• Sudden or sharp raw materials price increases may adversely affect our profit margins.

We utilize a variety of raw materials in the manufacture of our products, including base oil, polyisobutylene, antioxidants, alcohols, solvents, sulfonates, friction modifiers, olefins, and copolymers. Our profitability is sensitive to changes in the costs of these materials caused by changes in supply, demand or other market conditions, over which we have little or no control. Political and economic conditions in the Middle East and Latin America have caused, and may continue to cause, the cost of our raw materials to fluctuate. War, armed hostilities, terrorist acts, civil unrest, or other incidents may also cause a sudden or sharp increase in the cost of our raw materials. We cannot assure you that we will be able to pass on to our customers any future increases in raw material costs in the form of price increases for our products.

14

• Our reliance on a small number of significant customers may have a material adverse effect on our results of operations.

Our principal customers are major multinational oil companies. The oil industry is characterized by the concentration of a few large participants as a result of consolidation. The loss of a significant customer or a material reduction in purchases by a significant customer could have a material adverse effect on our results of operations, financial condition, and cash flow.

• Our customers are concentrated in the lubricant and fuel industries and, as a result, our reliance on that industry is significant.

Most of our customers are primarily engaged in the fuel and lubricant industries. This concentration of customers affects our overall risk profile, since our customers will be similarly affected by changes in economic, geopolitical, and industry conditions. Many factors affect the level of our customers’ spending on our products, including, among others, general business conditions, changes in technology, interest rates, gasoline prices, and consumer confidence in future economic conditions. A sudden or protracted downturn in these industries could adversely affect the buying power and purchases by our customers.

• We face risks related to our foreign operations that may negatively affect our business.

In 2010, sales to customers outside of the United States accounted for over 60% of consolidated revenue. We do business in all major regions of the world, some of which do not have stable economies or governments. In particular, we sell and market products in countries experiencing political and economic instability in the Middle East, Asia Pacific, and Latin America. Our international operations are subject to international business risks, including unsettled political conditions, expropriation, import and export restrictions, increases in royalties, exchange controls, national and regional labor strikes, taxes, government royalties, inflationary economies and currency exchange rate fluctuations, and changes in laws and policies governing operations of foreign-based companies (such as restrictions on repatriation of earnings or proceeds from liquidated assets of foreign subsidiaries). The occurrence of any one or a combination of these factors may increase our costs or have other adverse effects on our business.

• We are exposed to fluctuations in foreign exchange rates, which may adversely affect our results of operations.

We conduct our business in the local currency of most of the countries in which we operate. The financial condition and results of operations of our foreign operating subsidiaries are reported in the relevant local currency and then translated to U.S. Dollars at the applicable currency exchange rate for inclusion in our consolidated financial statements. Changes in exchange rates between these foreign currencies and the U.S. Dollar will affect the recorded levels of our assets and liabilities, as well as our revenues, costs, and operating margins. The primary foreign currencies in which we have exchange rate fluctuation exposure are the European Union Euro, British Pound Sterling, Japanese Yen, and Canadian Dollar. Exchange rates between these currencies and the U.S. Dollar have fluctuated significantly in recent years and may do so in the future.

• Political, economic, and regulatory factors concerning one of our products, mmt^®, could adversely affect our sales of mmt^®.

The United States EPA studied mmt^® and determined that it does not cause or contribute to the failure of vehicle emission systems. The Canadian government has made similar findings. The EPA also required, under certain provisions of the Clean Air Act, additional testing to fill some data gaps, including potential risks to public health. The final report for the mmt^® Alternative Tier 2 Health Testing Program was accepted and requirements of the mandated program were deemed to have been met with submission of a June 2009 report to the EPA. No change in current determinations has been made. In December 2003, the government of Canada released its “Proposed Framework for an

15

Independent Third-Party Review of New Information on the Effects of mmt^® Vehicle Emissions.” In its proposal, the Canadian government provided no timetable for the commencement or completion of the review, and to date, the government of Canada has not initiated the review.

The European Union (EU) finalized the latest version of the EU Fuel Quality Directive in December 2008, rejecting a proposed ban on mmt^® by the European Parliament’s Environmental Committee but implementing interim use limits and labeling requirements while a scientific risk assessment on metallic additives is carried out. A legal challenge initiated by Afton, seeking removal of these limits and labeling requirements while a risk assessment is underway, was rejected in 2010. The EU has not yet initiated a risk assessment for metallic additives.

Certain industry and other interest groups continue to urge greater regulation of all metal-based gasoline additives, including mmt^®. These industry groups include the Alliance of Automobile Manufacturers (AAM), the Association of International Automobile Manufacturers, and the Canadian Vehicle Manufacturers’ Association, who allege generally that metallic additives impair the proper operation of vehicle emission control systems. Increased government regulation of mmt^®, if it occurs, or additional studies evaluating metallic additives, even if government regulation does not occur, could have a material adverse effect on our sales of mmt^®.

• Our business is subject to government regulation and could be adversely affected by future governmental regulation.

We are subject to regulation by local, state, federal, and foreign governmental authorities. In some circumstances, before we may sell certain products, these authorities must approve these products, our manufacturing processes, and facilities. We are also subject to ongoing reviews of our products, manufacturing processes, and facilities by governmental authorities.

In order to obtain regulatory approval of certain new products, we must, among other things, demonstrate to the relevant authority that the product is safe and effective for its intended uses and that we are capable of manufacturing the product in accordance with current regulations. The process of seeking approvals can be costly, time consuming, and subject to unanticipated and significant delays. There can be no assurance that approvals will be granted to us on a timely basis, or at all. Any delay in obtaining, or any failure to obtain or maintain, these approvals would adversely affect our ability to introduce new products and to generate sales from those products.

New laws and regulations, including climate change regulations, may be introduced in the future that could result in additional compliance costs, seizures, confiscation, recall, or monetary fines, any of which could prevent or inhibit the development, distribution, and sale of our products. If we fail to comply with applicable laws and regulations, we may be subject to civil remedies, including fines, injunctions, and recalls or seizures, any of which could have an adverse effect on our results of operations, financial condition, and cash flows.

Our business and our customers are subject to significant regulations under the European Commission’s Registration, Evaluation and Authorization of Chemicals (REACH) regulation. REACH became effective on June 1, 2007. It imposes obligations on European Union manufacturers and importers of chemicals and other products into the European Union to compile and file comprehensive reports, including testing data, on each chemical substance, perform chemical safety assessments, and obtain pre-market authorization with respect to certain substances of particularly high concern. The regulation imposes significant additional burdens on chemical producers and importers, and, to a lesser extent, downstream users of chemical substances and preparations. Our manufacturing presence and sales activities in the European Union will require us to incur significant additional compliance costs.

• Legal proceedings and other claims could impose substantial costs on us.

We are involved in numerous administrative and legal proceedings that result from, and are incidental to, the conduct of our business. From time to time, these proceedings involve environmental, product liability, TEL, premises asbestos liability, and other matters. See Item 3, “Legal Proceedings.” We have

16

insurance coverage that we believe would be available to mitigate potential damages in many of these proceedings. However, there is no assurance that our available insurance will cover these claims, that our insurers will not challenge coverage for certain claims, or that final damage awards will not exceed our available insurance coverage. Any of the foregoing could have a material adverse effect on our results of operations, financial condition, and cash flows in any given period.

• Environmental matters could have a substantial negative impact on our results of operations.

As a manufacturer and distributor of chemical products, we are generally subject to extensive local, state, federal, and foreign environmental, safety, and health laws and regulations concerning, among other things, emissions to the air, discharges to land and water, the generation, handling, treatment, and disposal of hazardous waste and other materials, and remediation of contaminated soil, surface, and ground water. Our operations entail the risk of violations of those laws and regulations, many of which provide for substantial fines and criminal sanctions for violations. We believe that we comply in all material respects with laws, regulations, statutes, and ordinances protecting the environment, including those related to the discharge of materials. However, we cannot assure you that we have been or will be at all times in compliance with all of these requirements.

In addition, these requirements, and the enforcement or interpretation of these requirements, may become more stringent in the future. Although we cannot predict the ultimate cost of compliance with any such requirements, the costs could be material. Noncompliance could subject us to material liabilities, such as government fines, damages arising from third-party lawsuits, or the suspension and potential cessation of noncompliant operations. We may also be required to make significant site or operational modifications at substantial cost. Future developments could also restrict or eliminate the use of or require us to make modifications to our products, which could have an adverse effect on our results of operations, financial condition, and cash flows in any given period.

At any given time, we are involved in claims, litigation, administrative proceedings, and investigations of various types in a number of jurisdictions involving potential environmental liabilities, including clean-up costs associated with waste disposal sites, natural resource damages, property damage, and personal injury. We cannot assure you that the resolution of these environmental matters will not have an adverse effect on our results of operations, financial condition, and cash flows in any given period.

There may be environmental problems associated with our properties of which we are unaware. Some of our properties contain, or may have contained in the past, on-site facilities or underground tanks for the storage of chemicals, hazardous materials, and waste products that could create a potential for release of hazardous substances or contamination of the environment. The discovery of environmental liabilities attached to our properties could have a material adverse effect on our results of operations, financial condition, and cash flows.

We may also face liability arising from current or future claims alleging personal injury, product liability, property damage due to exposure to chemicals or other hazardous substances, such as premises asbestos, at or from our facilities. We may also face liability for personal injury, product liability, property damage, natural resource damage, or clean-up costs for the alleged migration of contaminants or hazardous substances from our facilities or for future accidents or spills. A significant increase in the number or success of these claims could adversely affect our financial condition, results of operations, and cash flows. For further discussion of some related claims, see Item 1, “Business—Environmental.”

The ultimate costs and timing of environmental liabilities are difficult to predict. Liability under environmental laws relating to contaminated sites can be imposed retroactively and on a joint and several basis. A liable party could be held responsible for all costs at a site, whether currently or formerly owned or operated regardless of fault, knowledge, timing of the contamination, cause of the contamination, percentage of contribution to the contamination, or the legality of the original disposal. We could incur significant costs, including clean-up costs, natural resource damages, civil or criminal

17

fines and sanctions, and third-party claims, as a result of past or future violations of, or liabilities under, environmental laws.

• We have been identified, and in the future may be identified, as a PRP in connection with state and federal laws regarding environmental clean-up projects.

We are subject to the federal, state and local environmental laws under which we may be designated as a PRP. As a PRP, we may be liable for a share of the costs associated with cleaning up hazardous waste sites, such as a landfill to which we may have sent waste.

In de minimis PRP matters and in some minor PRP matters, we generally negotiate a consent decree to pay an apportioned settlement. This relieves us of any further liability as a PRP, except for remote contingencies. We are also a PRP at sites where our liability may be in excess of the de minimis or minor PRP levels. Most sites where we are a PRP represent environmental issues that are quite mature. The sites have been investigated, and in many cases, the remediation methodology, as well as the proportionate shares of each PRP, has been established. Other sites are not as mature, which makes it more difficult to reasonably estimate our share of future clean-up or remediation costs. Generally, environmental remediation and monitoring will go on for an extended period. As a result, we may incur substantial expenses for all these sites over a number of years.

Liability for investigation and remediation of hazardous substance contamination at currently or formerly owned or operated facilities or at third-party waste disposal sites is joint and several. Currently, we are involved in active remediation efforts at several sites where we have been named a PRP. If other PRPs at these sites are unable to contribute to the remediation costs, we could be held responsible for some, or all, of their portion of the remediation costs, in addition to the portions for which we have already accounted.

• Restrictive covenants in our debt instruments may adversely affect our business.

Our senior credit agreement and senior notes contain restrictive covenants. These covenants may constrain our activities and limit our operational and financial flexibility. The failure to comply with these covenants could result in an event of default, which, if not cured or waived, could have a material adverse effect on our business, financial condition, and results of operations.

• The insurance that we maintain may not fully cover all potential exposures.

We maintain property, business interruption, and casualty insurance, but such insurance may not cover all risks associated with the hazards of our business and is subject to limitations, including deductibles and maximum liabilities covered. We may incur losses beyond the limits, or outside the coverage, of our insurance policies, including liabilities for environmental remediation. In the future, we may not be able to obtain coverage at current levels, and our premiums may increase significantly on coverage that we maintain.

• Landlord and financing risks associated with Foundry Park I could adversely affect our financial results.

In January 2007, Foundry Park I entered into a Deed of Lease Agreement with MeadWestvaco under which it is leasing an office building which we have constructed on approximately three acres.

Our landlord and financing activities may subject us to the following risks:

• We may incur costs associated with our landlord activities that exceed our expectations and result in the Foundry Park I operations materially negatively impacting our results of operations for our real estate development segment; and

• we may incur losses, which could be material, under the Goldman Sachs interest rate swap agreement. See Note 16 for further information on the interest rate swap.

18

• We may not be able to complete recent or future acquisitions or successfully integrate recent or future acquisitions into our business, which could result in unanticipated expenses and losses.

As part of our business growth strategy, we intend to pursue acquisitions and joint venture opportunities. Our ability to implement this component of our growth strategy will be limited by our ability to identify appropriate acquisition or joint venture candidates and our financial resources, including available cash and borrowing capacity. The expense incurred in completing acquisitions or entering into joint ventures, the time it takes to integrate an acquisition, or our failure to integrate businesses successfully, could result in unanticipated expenses and losses. Furthermore, we may not be able to realize any of the anticipated benefits from acquisitions or joint ventures.

The process of integrating acquired operations into our existing operations may result in unforeseen operating difficulties and may require significant financial resources that would otherwise be available for the ongoing development or expansion of existing operations.

• Our financial results will vary according to the timing of customer orders and other external factors, which complicates your ability to gauge our performance.

External factors beyond our control, such as customer orders, product shipment dates, and other factors can cause shifts in net sales and income from quarter to quarter. These external factors can magnify the impact of industry cycles. As a result, our income and cash flows may fluctuate significantly on a quarter-to-quarter basis, and your ability to gauge trends in our business may be impaired.

• We could be required to make additional contributions to our pension plans, which may be underfunded due to any underperformance of the equities markets.

Our pension plan asset allocation is predominantly weighted towards equities. Cash contribution requirements to our pension plans are sensitive to changes in our plans’ actual return on assets. Reductions in our plans’ return on assets due to poor performance of the equities markets could cause our pension plans to be underfunded and require us to make additional cash contributions.

NewMarket Development Corporation manages the property and improvements that we own on a site in Richmond, Virginia consisting of approximately 64 acres. We have our corporate offices on this site, as well as a research and testing facility, the office complex we constructed for Foundry Park I, and several acres dedicated to other uses. We are currently exploring various development opportunities for portions of the property as the demand warrants. This effort is ongoing in nature, as we have no specific timeline for any future developments.

In January 2007, Foundry Park I entered into a Deed of Lease Agreement with MeadWestvaco under which it is leasing the office building which we constructed on approximately three acres.

Production Capacity

We believe our plants and supply agreements are sufficient to meet expected sales levels. Operating rates of the plants vary with product mix and normal sales swings. We believe that our facilities are well maintained and in good operating condition.

ITEM 3. LEGAL PROCEEDINGS

We are involved in legal proceedings that are incidental to our business and include administrative or judicial actions seeking remediation under environmental laws, such as Superfund. Some of these legal proceedings relate to environmental matters and involve governmental authorities. For further information, see “Environmental” in Part I, Item 1.

While it is not possible to predict or determine with certainty the outcome of any legal proceeding, we believe the outcome of any of these proceedings, or all of them combined, will not result in a material adverse effect on our consolidated financial condition or results of operations.

On July 23, 2010, Afton Chemical Corporation and NewMarket Corporation filed a complaint in Federal District Court in Richmond, Virginia against Innospec. The complaint alleges that Innospec violated the Robinson-Patman Act, the Sherman Act, the Virginia Antitrust Act and Virginia Business Conspiracy Act based on the disclosures that Innospec recently made in its plea agreements with the U.S. Department of Justice and the Securities and Exchange Commission, as well as the UK Serious Fraud Office. In those agreements, Innospec pled guilty to violating the Foreign Corrupt Practices Act by bribing government officials in Iraq and Indonesia. Innospec paid the bribes to secure the sale of its product and to exclude NewMarket’s product in Iraq and Indonesia. Afton Chemical Corporation and NewMarket Corporation are seeking treble damages, all reasonable attorneys’ fees, expenses, and costs for injuries sustained as a result of these bribes.

PART II

ITEM 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

Our common stock, with no par value, has traded on the New York Stock Exchange (NYSE) under the symbol “NEU” since June 21, 2004 when we became the parent holding company of Ethyl, Afton, NewMarket Services, and their subsidiaries. We had 3,025 shareholders of record at January 31, 2011.

On July 31, 2008, our Board of Directors approved a share repurchase program that authorized management to repurchase up to $100 million of NewMarket’s outstanding common stock until December 31, 2010, as market conditions warrant and covenants under our existing agreements permitted. We could conduct the share repurchases in the open market and in privately negotiated transactions. The repurchase program did not require NewMarket to acquire any specific number of shares and could be terminated or suspended at any time. The 2008 repurchase program was terminated on July 21, 2010.

Also, on July 21, 2010, our Board of Directors approved a new share repurchase program authorizing management to repurchase up to $200 million of NewMarket’s outstanding common stock until December 31, 2012, as market conditions warrant and covenants under our existing agreements permit. We may conduct the share repurchases in the open market and in privately negotiated transactions. The repurchase program does not require NewMarket to acquire any specific number of shares and may be terminated or suspended at any time. Approximately $154.4 million remained available under the 2010 authorization at December 31, 2010. The following table outlines the purchases during the fourth quarter 2010 under this authorization.

Notes to the Five Year Summary

(1) Special item income, net was $14.8 million in 2006 and included a $5.3 million gain related to an earn-out agreement for certain pharmaceutical intellectual property that we sold in 1994; a $3.3 million gain associated with a legal settlement related to transportation charges; a $5.5 million gain resulting from a class action lawsuit related to raw materials; a $2.5 million loss from a legal settlement; and a $3.3 million gain on the sale of property.

(2) In December 2006, we purchased $149.75 million of the outstanding $150 million aggregate principal amount of our 8.875% senior notes due 2010 in a tender offer. As a result of the transaction, we recognized a loss of $11 million on the early extinguishment of debt. This loss included the write-off of unamortized deferred financing costs of $2.6 million and cash paid of $8.6 million related to the premium and other costs of the purchase of the senior notes. Subsequently in December 2006, we issued $150 million aggregate principal amount of our 7.125% senior notes due in 2016.

(3) Other (expense) income, net in 2010 and 2009 included the loss on the interest rate swap we entered into on June 25, 2009. The loss on the interest rate swap was $10.3 million for the twelve months ended December 31, 2010 and $11.4 million for the twelve months ended December 31, 2009. We are not using hedge accounting to record the interest rate swap, and accordingly, any change in the fair value is immediately recognized in earnings. Other (expense) income, net in both 2008 and 2007 consists primarily of investment income. Other (expense) income, net in 2006 includes a gain of $4 million for interest on an income tax settlement, as well as $2 million of investment income.

(4) Income tax expense in 2007 included a special item of $9.5 million primarily representing a reversal of deferred tax provisions that were previously provided on the undistributed earnings of certain foreign subsidiaries.

(5) Discontinued operations for 2007 and 2006 reflect the April 1, 2007 termination of all marketing agreements between the subsidiaries of Ethyl and Innospec. The gain on the termination of this business was $22.8 million ($14.6 million after tax). The remaining amounts reflect the after-tax earnings of this business.

(6) Of the total research, development, and testing expenses, the portion related to new products and processes was $45 million in 2010, $46 million in 2009, $44 million in 2008, $42 million in 2007, and $37 million in 2006.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATION

Forward-Looking Statements

The following discussion, as well as other discussions in this Annual Report on Form 10-K, contains forward-looking statements about future events and expectations within the meaning of the Private Securities Litigation Reform Act of 1995. We have based these forward-looking statements on our current expectations and projections about future results. When we use words in this document such as “anticipates,” “intends,” “plans,” “believes,” “estimates,” “expects,” “should,” “could,” “may,” “will,” and similar expressions, we do so to identify forward-looking statements. Examples of forward-looking statements include statements we make regarding future prospects of growth in the petroleum additives market, our ability to maintain or increase our market share, and our future capital expenditure levels.

We believe our forward-looking statements are based on reasonable expectations and assumptions, within the bounds of what we know about our business and operations. However, we offer no assurance that actual results will not differ materially from our expectations due to uncertainties and factors that are difficult to predict and beyond our control.

These factors include, but are not limited to, availability of raw materials and transportation systems; supply disruptions at single sourced facilities; ability to respond effectively to technological changes in our industry; failure to protect our intellectual property rights; hazards common to chemical businesses; occurrence or threat of extraordinary events, including natural disasters and terrorist attacks; competition from other manufacturers; sudden or sharp raw materials price increases; gain or loss of significant customers; risks related to operating outside of the United States; the impact of fluctuations in foreign exchange rates; political, economic, and regulatory factors concerning our products; future governmental regulation; resolution of environmental liabilities or legal proceedings; and inability to complete recent or future acquisitions or successfully integrate recent or future acquisitions into our business. In addition, certain risk factors are also discussed in Item 1A, “Risk Factors.”

You should keep in mind that any forward-looking statement made by us in this discussion or elsewhere speaks only as of the date on which we make it. New risks and uncertainties arise from time to time, and it is impossible for us to predict these events or how they may affect us. We have no duty to, and do not intend to, update or revise the forward-looking statements in this discussion after the date hereof, except as may be required by law. In light of these risks and uncertainties, you should keep in mind that any forward-looking statement made in this discussion, or elsewhere, might not occur.

OVERVIEW

We had many accomplishments in 2010 as we realized record profits and reached a return of product demand to pre-recessionary levels. Our petroleum additives business attained the highest profits on record through strong sales volumes and operating margins that reflect the value our technology-driven products provide to our customers. Our plants are running safely at high levels; we increased our production capacity in Singapore; we expanded our capability in research and development through new investment in people and facilities; and we expanded our regional presence to better meet our customers’ needs.

In addition, we completed the acquisition of the Polartech group of companies (Polartech), a leading metal working additive company, which provides Afton an opportunity to further expand in the industrial additives market.

Our Foundry Park project was operational for the entire year with long-term financing being secured in January 2010 and the tenant occupying the entire building, as expected.

Finally, our financial position remains strong, with $49 million of cash on our balance sheet. We obtained a new, unsecured $300 million revolving line of credit from a group of banks, replacing the $150 million secured facility. We also repurchased $125 million of our common stock during the year.

RESULTS OF OPERATIONS

Revenue

Our consolidated revenue for 2010 amounted to $1,797 million, representing an increase of approximately 17% from $1,530 million in 2009. The decrease of $87 million between 2009 and 2008 was 5%.

Net sales to one customer of our petroleum additives segment exceeded 10% of consolidated revenue in 2010, 2009, and 2008. Sales to Royal Dutch Shell plc and its affiliates (Shell) amounted to $217 million (12% of consolidated revenue) in 2010, $232 million (15% of consolidated revenue) in 2009, and $261 million (16% of consolidated revenue) in 2008. These sales represent a wide-range of products sold to this customer in multiple regions of the world.

No other single customer accounted for 10% or more of our total revenue in 2010, 2009, or 2008.

The following table shows revenue by segment for each of the last three years.

Consolidated Revenue by Segment

(in millions of dollars)

	2010		2009		2008
Petroleum additives	$	1,774	$	1,518	$	1,604
Real estate development		11		0		0

Consolidated revenue	$	1,797	$	1,530	$	1,617

Petroleum Additives—Net sales of our petroleum additives segment were higher in 2010 than in 2009, while 2009 petroleum additives net sales were lower than 2008.

Net sales in 2010 of $1,774 million were $256 million or 17% higher than 2009 net sales of $1,518 million. The increase in net sales reflects higher total product shipments of 12%, including the benefit of Polartech shipments during 2010. The increase in product shipments was across most product lines, but primarily in the lubricant additives product lines. Selling prices were also favorable for 2010 as compared to 2009. An unfavorable foreign currency impact of $6 million partially offset the increase in product shipments and selling prices. While recovering in 2009 from the worldwide economic slowdown, product shipments were weaker than normal during the first half of 2009. We believe the overall demand for petroleum additive products has recovered from recessionary effects and are now at levels consistent with normal market demands.

Net sales in 2009 of $1,518 million were $86 million or 5% lower than the 2008 amount of $1,604 million. The decrease between the two years reflects lower total product shipments, as well as a significant unfavorable foreign currency impact of $21 million. Product shipments were 9% lower when comparing 2009 and 2008. The decrease in shipments was primarily in the lubricant additives product lines, which was partially offset by a modest increase in fuel additives product lines shipments. While product shipments were lower when comparing the two years, when comparing the second half of each year, shipments increased 6% in 2009 over 2008. The unfavorable impact on net sales between 2009 and 2008 from shipments was partially offset by higher selling prices, which were implemented in 2008. The unfavorable impact from foreign currency reflects the strengthening of the U.S. Dollar between 2009 and 2008 versus the other currencies in which we conduct business.

27

The approximate components of the petroleum additives increase in net sales of $256 million when comparing 2010 to 2009 and the decrease in net sales of $86 million when comparing 2009 to 2008 are shown below in millions.

Net sales for year ended December 31, 2008	$	1,604
Decrease in shipments, including changes in product mix		(141	)
Increase in selling prices, including changes in customer mix		76

Net sales for year ended December 31, 2010	$	1,774

Real Estate Development Segment—The revenue of $11 million for the real estate development segment represents the rental of the office building, which was constructed by Foundry Park I. The building was completed in late 2009, and we began recognizing rental revenue in January 2010.

Segment Operating Profit

NewMarket evaluates the performance of the petroleum additives business and the real estate development business based on segment operating profit. NewMarket Services departmental and other expenses are billed to NewMarket and each subsidiary pursuant to services agreements between the companies. Depreciation on segment property, plant, and equipment, as well as amortization of segment intangible assets is included in the segment operating profit.

The “All other” category includes the continuing operations of the TEL business (primarily sales of TEL in North America), as well as certain contract manufacturing Ethyl provides to Afton and to third parties.

The table below reports operating profit by segment for the last three years.

Segment Operating Profit

(in millions of dollars)

	2010		2009			2008
Petroleum additives	$	299	$	280		$	130
Real estate development	$	7	$	(1	)	$	0
All other	$	3	$	0		$	2

Petroleum Additives—The petroleum additives operating profit increased $19 million when comparing 2010 and 2009. The operating profit margin was 16.9% for 2010 and 18.4% for 2009. When compared to 2009 operating profit levels, the 2010 results are higher across the lubricant additives product lines, but lower across the fuel additives product lines. Substantially increased product shipments and somewhat higher selling prices, as well as the benefit of the Polartech acquisition, as discussed in the Revenue section above, were significant favorable factors in the operating profit when compared to 2009. Partially offsetting these favorable factors on operating profit, were unfavorable impacts from margin compression, as well as planned additional spending in selling, general, and administrative expenses. While operating profit improved in 2010 over 2009, the operating profit margin was unfavorable when comparing the two years. The lower 2010 operating profit margin reflects increased raw material costs and less favorable product mix resulting from the decrease of shipments of certain high margin products. In response to the increase of raw material costs during 2010, we have been implementing selling price increases.

28

The petroleum additives operating profit increased $150 million when comparing 2009 and 2008. The operating profit margin of 18.4% for 2009 compares to 8.1% for 2008. The 2008 results included a gain of $3 million resulting from a legal settlement related to raw materials. The 2009 results are significantly higher across all product lines. The most significant factors when comparing operating profit and the operating profit margins between 2009 and 2008 were higher selling prices, as discussed in the Revenue section above, and lower raw material costs. While partially offset by selling price reductions made during 2009, the overall increase in selling prices for 2009 is the result of actions taken throughout 2008 to raise selling prices in response to the then increasing raw material costs. The key unfavorable factor in operating profit results between 2009 and 2008 was lower product shipments, also discussed in the Revenue section. During the second half of 2009, we experienced increasing raw material costs and tightening in the availability of certain raw materials.

Finally, our selling, general, and administrative expenses (SG&A), together with research, development, and testing expenses (R&D), were $25 million, or 14%, higher in 2010 than 2009, and $2 million, or 1%, higher in 2009 than 2008.

In 2010, SG&A increased approximately $19 million, or 21%, over 2009 levels. The increase was primarily the result of certain growth-related costs, largely reflecting the inclusion of the Polartech operations in 2010, as well as higher personnel-related costs and professional fees. SG&A was approximately $3 million, or 3%, lower when comparing 2009 and 2008. The decrease resulted primarily from favorable foreign currency, partially offset by higher personnel-related costs. Total R&D for petroleum additives was $91 million in 2010, $86 million in 2009, and $82 million in 2008. We continue to invest in SG&A and R&D to support our customers’ programs and to develop the technology required to remain a leader in this industry. We expect this to continue for the foreseeable future. R&D related to new products and processes was $45 million in 2010, $46 million in 2009, and $44 million in 2008. All of our R&D was related to the petroleum additives segment.

Real estate development—Operating profit for the real estate development segment was $7 million for 2010, compared to a loss of $1 million for 2009. During 2009, the office building was under construction resulting in no rental revenue and limited non-capital expenses.

The following discussion references certain captions on the Consolidated Statements of Income.

Interest and Financing Expenses

Interest and financing expenses were $17.3 million in 2010, $11.7 million in 2009, and $12.0 million in 2008. The increase in interest and financing expenses between 2010 and 2009 was primarily related to the mortgage loan on the Foundry Park I office building, as well as higher average outstanding debt on the revolving credit facility during 2010. Prior to obtaining the mortgage loan in January 2010, the interest and financing expenses for the construction phase of the office building were capitalized. The small decrease in interest and financing expenses between 2009 and 2008 resulted primarily from lower average debt between the two years, as we had no drawn debt on the revolving credit facility during most of 2009. The lower debt was partially offset by slightly higher interest rates and higher amortization of deferred financing costs in 2009 due to the cost related to increased commitment levels achieved on the revolving credit facility.

Other (Expense) Income, Net

Other (expense) income, net was $10 million expense in 2010, $11 million expense in 2009, and $1 million income in 2008. The 2010 and 2009 amounts primarily represent the loss on an interest rate swap which is recorded at fair value. See Note 16 for additional information on the interest rate swap. The 2008 amount resulted primarily from investment income.

Income Tax Expense

Income tax expense was $83 million in 2010, $77 million in 2009, and $32 million in 2008. The effective tax rate was 31.9% in 2010, 32.2% in 2009, and 30.5% in 2008. The 2010 and 2008 effective income tax rates include the

29

benefit of higher income in foreign jurisdictions with lower tax rates. The 2010 and 2009 effective income tax rates include a substantial benefit from the domestic manufacturing tax deduction. The effective tax rate in each year reflects certain foreign and other tax benefits. See Note 22 for further details on income taxes.

The increase in income before income tax expense between 2009 and 2010 resulted in an increase in tax expense of $7 million. This was partially offset by a reduction in tax expense of $1 million due to the lower effective tax rate in 2010 compared to 2009.

The increase in income before income tax expense between 2008 and 2009 resulted in an increase in tax expense of $41 million. The remaining change in income tax expense resulted from the higher effective tax rate, which primarily reflects the higher proportion of domestic earnings in 2009, which are subject to both U.S. federal and state income taxes.

Our deferred taxes are in a net asset position. Based on current forecast operating plans and historical profitability, we believe that we will recover nearly the full benefit of our deferred tax assets and have, therefore, recorded an immaterial valuation allowance at a foreign subsidiary.

CASH FLOWS DISCUSSION

We generated cash from operating activities of $165 million in 2010, $224 million in 2009, and $21 million in 2008.

During 2010, we utilized the $165 million of cash generated from operations and $103 million of cash on hand, along with the borrowing of $68 million under the mortgage loan for Foundry Park I and $4 million under the revolving credit facility to fund several key initiatives. These initiatives included repaying the Foundry Park I construction loan of $99 million. We also funded the acquisition of Polartech for $41 million, funded capital expenses of $36 million, repurchased $122 million of our common stock, paid $23 million of dividends on our common stock, made a net deposit of $8 million related to the Goldman Sachs interest rate swap, paid $4 million for debt issuance costs, and made a net payment of $2 million for settlements under the mortgage loan interest rate swap. Further information on the Goldman Sachs and mortgage loan interest rate swaps is in Note 16. These cash flows included an unfavorable foreign currency impact on cash of $2 million. Cash flows from operating activities included a decrease of $63 million resulting from higher working capital requirements and payments of $22 million for our pension and postretirement plans.

During 2009, we used the cash generated from operations, along with $56 million of draws under the Foundry Park I construction loan and $11 million from a net return of funds for the deposit related to an interest rate lock agreement to fund $89 million of capital expenditures, payoff the outstanding balance of $42 million on the revolving credit agreement, and make a net deposit of $15 million related to the Goldman Sachs interest rate swap. We also paid dividends on our common stock of $16 million. These items, including a favorable fluctuation in foreign currency rates of $5 million, resulted in an increase of $130 million in cash and cash equivalents. Cash flows from operating activities included an increase of $23 million resulting from lower working capital requirements, as well as payments of $25 million for our pension and postretirement plans.

As of December 31, 2008, we had $42 million outstanding under our revolving credit agreement and had made draws of $38 million under the Foundry Park I construction loan. We used these borrowings, as well as cash provided from operating activities to fund $75 million of capital expenditures, $27 million for repurchase of our common stock, $15 million for dividends on our common stock, and $15 million for the acquisition of a business. In addition, we also funded $10 million cash for the net deposit on an interest rate lock agreement. Our book overdraft decreased $5 million. These items, combined with an unfavorable foreign exchange effect on cash of $4 million, resulted in a decrease in cash and cash equivalents of $50 million. Cash flows from operating activities included a decrease of $91 million due to higher working capital requirements, payments of $17 million to fund our pension and postretirement plans, and proceeds of $3 million for a legal settlement related to raw materials. The higher working capital requirements during the year primarily reflected a reduction in outstanding accounts payable at the end of 2008, as well as higher inventory costs during the year.

30

We expect that cash from operations, together with borrowing available under our senior credit facility, will continue to be sufficient to cover our operating expenses and planned capital expenditures for at least the next twelve months.

FINANCIAL POSITION AND LIQUIDITY

Cash

At December 31, 2010, we had cash and cash equivalents of $49 million as compared to $152 million at the end of 2009.

At both December 31, 2010 and December 31, 2009, we had a book overdraft for some of our disbursement cash accounts. A book overdraft represents disbursements that have not cleared the bank accounts at the end of the reporting period. We transfer cash on an as-needed basis to fund these items as they clear the bank in subsequent periods.

Debt

Senior Notes—The 7.125% senior notes are our senior unsecured obligations and are jointly and severally guaranteed on an unsecured basis by all of our existing and future 100% owned by NewMarket domestic restricted subsidiaries. We incurred financing costs of approximately $3 million in 2006 related to the 7.125% senior notes, which are being amortized over ten years.

The 7.125% senior notes and the subsidiary guarantees rank:

• effectively junior to all of our and the guarantors’ existing and future secured indebtedness, including any borrowings under the senior credit facility described below;

• equal in right of payment with any of our and the guarantors’ existing and future unsecured senior indebtedness; and

• senior in right of payment to any of our and the guarantors’ existing and future subordinated indebtedness.

The indenture governing the 7.125% senior notes contains covenants that, among other things, limit our ability and the ability of our restricted subsidiaries to:

• incur additional indebtedness;

• create liens;

• pay dividends or repurchase capital stock;

• make certain investments;

• sell assets or consolidate or merge with or into other companies; and

• engage in transactions with affiliates.

The more restrictive and significant of the covenants under the indenture include a minimum fixed charge ratio of 2.00, as well as a limitation on restricted payments, as defined in the indenture. Our fixed charge coverage ratio was 19.46 at December 31, 2010 and 22.62 at December 31, 2009. In addition, we would have been permitted to make additional restricted payments in the amount of approximately $50 million at December 31, 2010 and $84 million at December 31, 2009. In January 2011, we obtained consents from the holders of the senior notes to modify the formula for calculating the capacity under the senior notes to make certain restricted payments. Had the consent been effective at year-end 2010, we would have been permitted to make additional restricted payments in the amount of approximately $150 million at December 31, 2010.

We were in compliance with all covenants under the indenture governing the 7.125% senior notes as of December 31, 2010 and December 31, 2009.

Senior Credit Facility—On November 12, 2010, we entered into a Credit Agreement (Credit Agreement). The Credit Agreement provides for a $300 million, multicurrency revolving credit facility, with a $100 million sublimit for multicurrency borrowings, a $100 million sublimit for letters of credit, and a $20 million sublimit for swingline loans. The Credit Agreement includes an expansion feature, which allows us, subject to certain conditions, to request to increase the aggregate amount of the revolving credit facility or obtain incremental term loans in an amount up to $150 million. We used the proceeds from the Credit Agreement to pay off the outstanding balance of $35 million on our previous revolving credit agreement. Our previous revolving credit agreement was terminated on November 12, 2010.

At December 31, 2010, we had outstanding letters of credit of $5.1 million and $4 million borrowed, resulting in the unused portion of the senior credit facility amounting to $290.9 million. For further information on the outstanding letters of credit, see Note 18.

We paid financing costs in 2010 of approximately $2.5 million related to this agreement and carried over deferred financing costs from our previous revolving credit agreement of approximately $700 thousand, resulting in total deferred financing costs of $3.2 million, which we are amortizing over the term of the Credit Agreement.

The obligations under the Credit Agreement are unsecured and are fully and unconditionally guaranteed by NewMarket and the subsidiary guarantors. The revolving credit facility matures on November 12, 2015.

Borrowing made under the revolving credit facility bear interest at an annual rate equal to, at our election, either (1) the ABR plus the Applicable Rate (solely in the case of loans denominated in U.S. dollars to NewMarket) or (2) the Adjusted LIBO Rate plus the Applicable Rate. ABR is the greatest of (i) the rate of interest publicly announced by the Administrative Agent as its prime rate, (ii) the federal funds effective rate from time to time plus 0.5% or (iii) the Adjusted LIBO Rate for a one month interest period plus 1%. The Adjusted LIBO Rate means the rate at which Eurocurrency deposits in the London interbank market for certain periods (as selected by NewMarket) are quoted, as adjusted for statutory reserve requirements for Eurocurrency liabilities and other applicable mandatory costs. Depending on our Leverage Ratio, the Applicable Rate ranges from 1.00% to 1.50% for loans bearing interest based on the ABR and from 2.00% to 2.50% for loans bearing interest based on the Adjusted LIBO Rate. At December 31, 2010, the Applicable Rate was 1.00% for loans bearing interest based on the ABR and 2.00% for loans bearing interest based on the Adjusted LIBO Rate. Our average interest rate under the Credit Agreement was 3.6% during 2010, while the combined average interest rate under both revolving credit agreements in effect during 2010 was 4.5%. At December 31, 2010, the interest rate was 4.25%.

The Credit Agreement contains financial covenants that require NewMarket to maintain a consolidated Leverage Ratio (as defined in the Credit Agreement) of no more than 3.00 to 1.00 and a consolidated Interest Coverage ratio (as defined in the Credit Agreement) of no less than 3.00 to 1.00, as of the end of each fiscal quarter ending on and after December 31, 2010. At December 31, 2010, the Leverage Ratio was 0.74 and the Interest Ratio was 16.50.

We were in compliance with all covenants under the Credit Agreement at December 31, 2010.

Mortgage Loan Agreement—On January 28, 2010, Foundry Park I entered into a mortgage loan agreement in the amount of $68.4 million. The loan, which is collateralized by the Foundry Park I office building, is for a period of five years, with two thirteen-month extension options. NewMarket Corporation is fully guaranteeing the loan. The mortgage loan bears interest at a variable rate of LIBOR plus a margin of 400 basis points, with a minimum LIBOR of 200 basis points. At December 31, 2010, the interest rate was 4.26%. Principal payments on the loan are being made monthly based on a 15 year amortization schedule, with all remaining amounts due in five years, unless we exercise the extension options. We incurred financing costs of $1.5 million related to the mortgage loan, which are being amortized over five years.

Concurrently with the closing of the mortgage loan, Foundry Park I obtained an interest rate swap to effectively convert the variable interest rate in the loan to a fixed interest rate by setting LIBOR at 2.642% for five years. Further information on the interest rate swap is in Note 16.

32

Construction Loan Agreement—Foundry Park I and NewMarket Corporation entered into a construction loan agreement with a group of banks on August 7, 2007 to borrow up to $116 million to fund the development and construction of an office building. The construction loan bore interest at LIBOR plus a margin of 140 basis points. The term of the loan was for a period of 36 months and was unconditionally guaranteed by NewMarket Corporation. No principal reduction payment became due during the construction period. As a condition of the construction loan and concurrently with the closing of the loan, Foundry Park I also obtained interest rate risk protection in the form of an interest rate swap. See Note 16. On January 29, 2010, we paid off the outstanding balance of $99.1 million of the construction loan with proceeds of $68.4 million from the mortgage loan agreement (discussed above) and cash on hand of $30.7 million.

Other Borrowings—One of our subsidiaries in India has a short-term line of credit of 110 million Rupees for working capital purposes. The average interest rate was approximately 9.8% during 2010 and 9.96% at December 31, 2010. The outstanding balance of $1.5 million at December 31, 2010 is due during 2011.

***

We had combined current and noncurrent long-term debt of $222 million at December 31, 2010 and $250 million at December 31, 2009. The decrease in debt resulted from the payment of the outstanding balance of $99 million on the construction loan, which was partially offset by net borrowings of $66 million on the mortgage loan, $4 million on the revolving credit facility, and $1 million under the line of credit of our subsidiary in India. In addition, during 2010, we also paid $800 thousand on our capital lease obligations.

As a percentage of total capitalization (total debt and shareholders’ equity), our total debt decreased from 35.3% at the end of 2009 to 31.1% at the end of 2010. The change in the percentage was primarily the result of the increase in shareholders’ equity and the decrease in debt. The increase in shareholders’ equity reflects our earnings, partially offset by the impact of dividend payments and the stock repurchase program. Normally, we repay long-term debt with cash from operations or refinancing activities.

Working Capital

At December 31, 2010, we had working capital of $396 million, resulting in a current ratio of 2.92 to 1. Our working capital at year-end 2009 was $405 million resulting in a current ratio of 3.05 to 1.

The change in the working capital ratio primarily reflects lower cash levels and prepaid expenses, as well as higher accounts payable at December 31, 2010. These were offset by higher accounts receivable and inventories, as well as lower current portion of long-term debt at December 31, 2010. The decrease in prepaid expenses reflects a reduction of prepaid taxes on intercompany profit in inventory, while the fluctuation in accounts payable results from normal differences in timing of payments and increased inventory purchases. The increase in inventories primarily reflects higher quantities at certain locations in response to demand for our products. The increase in accounts receivables primarily reflects higher sales levels when comparing fourth quarter 2010 and fourth quarter 2009, as well as an increase in our domestic tax receivable position. The decrease in the current portion of long-term debt resulted from the January 2010 payment of the construction loan and subsequent entry into the mortgage loan. The changes in the working capital components include a foreign currency impact, as well as the impact of Polartech since the March 2010 acquisition.

Capital Expenditures

We expect capital expenditures to be approximately $45 million to $50 million in 2011. We expect to continue to finance this capital spending through cash provided from operations, together with borrowing available under our senior credit facility.

Environmental Expenses

We spent approximately $18 million in 2010 and $17 million in both 2009 and 2008 for ongoing environmental operating and clean-up costs, excluding depreciation of previously capitalized expenditures. These environmental

33

operating and clean-up expenses are included in cost of goods sold. Further, we expect to continue to fund these costs through cash provided by operations.

Contractual Obligations

The table below shows our year-end contractual obligations by year due.

	Payments due by period (in millions of dollars)
	Total		Less than 1 Year		1 - 3 Years		3 - 5 Years		More than 5 Years

(a) Amounts represent contractual payments due on the senior notes, senior credit facility, mortgage loan, and short-term line of credit as of December 31, 2010. See Note 12 for more information on long-term debt obligations.

(b) We intend to renew letters of credit when necessary as they mature; therefore, the obligations do not have a definitive maturity date.

(c) Raw material purchase obligations include agreements to purchase goods or services that are enforceable and legally binding and that specify all significant terms, including: fixed or minimum quantities to be purchased; fixed, minimum, or variable price provisions; and the approximate timing of the transaction. Purchase obligations exclude agreements that are cancelable without penalty. Purchase orders made in the ordinary course of business are excluded from the above table. Any amounts for which we are liable under purchase orders are reflected in our Consolidated Balance Sheets as accounts payable or accrued expenses.

(d) These represent other long-term liability amounts reflected in our Consolidated Balance Sheets that have known payment streams. Amounts include environmental liabilities, including asset retirement obligations, as well as contributions associated with pension and postretirement benefit plans. Amounts accrued for the potential exposure with respect to litigation, claims, and assessments are not included in the table above.

Pension and Postretirement Benefit Plans

Our U.S. and foreign benefit plans are discussed separately below. Our U.S. pension and postretirement plans are similar and therefore, the information discussed below applies to all of our U.S. benefit plans. Our foreign plans are quite diverse, and the actual assumptions used by the various foreign plans are based upon the circumstances of each particular country and retirement plan. The discussion below surrounding our foreign retirement benefits focuses only on our pension plan in the United Kingdom (U.K.) which represents the majority of the impact on our financial statements from foreign pension plans. We use a December 31 measurement date to determine our pension and postretirement expenses and related financial disclosure information. Additional information on our pension and postretirement plans is in Note 19.

U.S. Pension and Postretirement Benefit Plans—The following information applies to our U.S. pension and postretirement benefit plans. The average remaining service period of active participants for our U.S. plans is 12.9 years, while the average remaining life expectancy of inactive participants is 24.9 years. We utilize the Optional Combined Mortality Tables for males and females based on the RP-2000 Mortality Tables projected with Scale AA as published by the IRS on February 2, 2007 in determining the impact of the U.S. benefit plans on our financial statements.

34

Investment Return and Asset Allocation—We periodically review our assumptions for the long-term expected return on pension plan assets. As part of the review and to develop expected rates of return, we considered a stochastic analysis of expected returns based on the U.S. plans’ asset allocation as of both January 1, 2009 and January 1, 2010. This forecast reflects our expected long-term rates of return for each significant asset class or economic indicator. As of January 1, 2011, the expected rates were 8.4% for U.S. large cap stocks, 3.6% for U.S. long-term corporate bonds, and 2.1% for inflation. The range of returns developed relies both on forecasts and on broad-market historical benchmarks for expected return, correlation, and volatility for each asset class.

Our asset allocation is predominantly weighted toward equities. Through our ongoing monitoring of our investments, we have determined that we should maintain the expected long-term rate of return for our U.S. plans at 9.0% at December 31, 2010.

An actuarial gain, where the actual return was higher than the expected return, occurred during 2010 and 2009 resulting in the actual investment return being higher than the expected return for all of our U.S. plans by approximately $4 million in 2010 and $10 million in 2009. An actuarial loss, where the actual return was lower than the expected return, occurred during 2008 resulting in the actual investment return being approximately $38 million lower than the expected return for all of our U.S. pension plans. This is consistent with the steep decline in the global stock markets during 2008. Investment gains and losses enter earnings on an amortized basis over a period of years so that the 2008 investment losses caused an increase in expense of approximately $1.5 million in 2010, as well as an expected $1.5 million increase in expense in 2011. We expect that there will be continued volatility in pension expense as actual investment returns vary from the expected return, but we continue to believe the potential long-term benefits justify the risk premium for equity investments.

Pension expense and the retiree medical portion of postretirement expense are sensitive to changes in the expected return on assets. For example, decreasing the expected rate of return by 25 basis points to 8.75% for pension assets and 6.0% for postretirement benefit assets (while holding other assumptions constant) would increase the forecasted 2011 expense for our U.S. pension and postretirement plans by approximately $375 thousand. Similarly, a 25 basis point increase in the expected rate of return to 9.25% for pension assets and 6.5% for postretirement benefit assets (while holding other assumptions constant) would reduce forecasted 2011 pension and postretirement expense by approximately $375 thousand.

Discount Rate Assumption—We utilize a proprietary model maintained by our actuarial consultant in developing the discount rate assumption. The model determines the single effective discount rate for a unique hypothetical portfolio constructed from investment-grade bonds that, in aggregate, match the projected cash flows of each of our retirement plans. Our discount rate is developed based on the hypothetical portfolio on the last day of December. The discount rate at December 31, 2010 was 5.875% for all plans.

Pension and postretirement benefit expense is also sensitive to changes in the discount rate. For example, decreasing the discount rate by 25 basis points to 5.625% (while holding other assumptions constant) would increase the forecasted 2011 expense for our U.S. pension and postretirement benefit plans by approximately $800 thousand. A 25 basis point increase in the discount rate to 6.125% would reduce forecasted 2011 pension and postretirement benefit expense by approximately $800 thousand.

Rate of Projected Compensation Increase—We have decreased our rate of projected compensation increase at December 31, 2010 from 4.00% to 3.50%. The rate assumption was based on an analysis of our projected compensation increases for the foreseeable future.

Liquidity—Cash contribution requirements to the pension plan are sensitive to changes in assumed interest rates and investment gains or losses in the same manner as pension expense. We expect our aggregate cash contributions, before income taxes, to the U.S. pension plans will be approximately $23 million in 2011. We expect our contributions to the postretirement benefit plans will be approximately $2 million.

35

Other Assumptions—During 2008, we reviewed our assumption for the health care cost trend rate. Based on actual cost experience, we restarted our overall assumption for health care cost increases at 10%, scaling down to 5.0% by 2018. We maintained this health care cost trend assumption for 2010 resulting in an assumed rate of 9.0% for 2010 and 8.5% for 2011. The assumption includes temporarily higher cost increases for our retiree prescription drug coverage.

At December 31, 2010, our expected long-term rate of return on our postretirement plans was 6.25%. This rate varies from the pension rate of 9.0% primarily because of the difference in investment of assets. The assets of the postretirement plan are held in an insurance contract, which results in a lower assumed rate of investment return.

Foreign Pension Benefit Plans – As discussed above, our foreign pension plans are quite diverse. The following information applies only to our U.K. pension plan, which represents the majority of the impact on our financial statements from our foreign pension plans. The average remaining service period for our U.K. plan is 13 years, while the average remaining life expectancy is 37 years. We utilize PA92 mortality tables which allow for future “medium cohort” projected improvements in life expectancy with a minimum 1% per year improvement and a -1 year age rating based on the membership of the plan, in determining the impact of the U.K. pension plans on our financial statements.

Investment Return Assumptions and Asset Allocation—We periodically review our assumptions for the long-term expected return on the U.K. pension plan assets. The expected long-term rate of return is based on both the asset allocation, as well as yields available in the U.K. markets.

The target asset allocation in the U.K. is to be invested 55% in equities, 40% in a mixture of government and corporate bonds, and 5% in a pooled investment property fund, although the actual allocation at the end of 2010 was 58% in equities, 37% in government and corporate bonds, and 5% in a pooled investment property fund. Based on the actual asset allocation and the expected yields available in the U.K. markets, the expected long-term rate of return for the U.K. pension plan was 6.0% at December 31, 2010.

An actuarial gain occurred during 2010 as the actual investment return exceeded the expected investment return in 2010 by approximately $5 million for our U.K. pension plan. This compares to an actuarial gain of $7 million in 2009 and an actuarial loss of $15 million in 2008. Investment gains and losses enter earnings on an amortized basis resulting in increased expense of approximately $1 million in 2010, as well as an expected $800 thousand increased expense in 2011. We expect that there will be continued volatility in pension expense as actual investment returns vary from the expected return, but we continue to believe the potential benefits justify the risk premium for the target asset allocation.

Pension expense is sensitive to changes in the expected return on assets. For example, decreasing the expected rate of return by 25 basis points to 5.75% (while holding other assumptions constant) would increase the forecasted 2011 expense for our U.K. pension plan by approximately $200 thousand. Similarly, a 25 basis point increase in the expected rate of return to 6.25% (while holding other assumptions constant) would reduce forecasted 2011 pension expense by approximately $200 thousand.

Discount Rate Assumption—We utilize a yield curve based on AA-rated corporate bond yields constructed from iBoxx indices in developing a discount rate assumption (extrapolated at longer terms based on the corresponding swap yield curve). The yield appropriate to the duration of the U.K. plan liabilities is then used. The discount rate at December 31, 2010 was 5.4%.

Pension expense is also sensitive to changes in the discount rate. For example, decreasing the discount rate by 25 basis points to 5.15% (while holding other assumptions constant) would increase the forecasted 2011 expense for our U.K. pension plans by approximately $200 thousand. A 25 basis point increase in the discount rate to 5.65% would reduce forecasted 2011 pension expense by approximately $200 thousand.

36

Rate of Projected Compensation Increase—We have increased our rate of projected compensation increase at December 31, 2010 to 5.10% from 4.55%. The rate assumption was based on an analysis of our projected compensation increases for the foreseeable future.

Liquidity—Cash contribution requirements to the U.K. pension plan are sensitive to changes in assumed interest rates in the same manner as pension expense. We expect our aggregate U.K. cash contributions, before income taxes, will be approximately $5 million in 2011.

OUTLOOK

We begin 2011 with high confidence in our business, as 2010 proved to be a record setting year. We believe the fundamentals of how we run our business—a safety-first culture, customer-focused solutions, technology-driven product offerings, world-class supply chain capability, and a regional organizational structure to better understand our customers’ needs—will continue to pay dividends to all of our stakeholders.

We expect 2011 to be a more profitable year than 2010, as we project an increase in both revenue and net income. Over the past several years, we have made significant investments to expand our capabilities around the globe. These investments have been in people, research centers, and production capacity. We intend to use these new capabilities to improve our ability to deliver the goods and service that our customers value and to expand our business and profits.

In summary, we expect the business practices that have produced the outstanding results of the past two years will continue next year. We expect that the macro-business environment in which we operate will improve as the world economies continue to strengthen.

Our business continues to generate significant amounts of cash beyond what is necessary for the expansion and growth of our current product lines. We regularly review the many internal opportunities which we have to utilize this cash, both from a geographical and product line point of view. We have increased our efforts in investigating potential acquisitions as both a use for this cash and to generate shareholder value. Our primary focus in the acquisition area remains on the petroleum additives industry. It is our view that this industry will provide the greatest opportunity for a good return on our investment while minimizing risk. We remain focused on this strategy and will evaluate any future opportunities. Nonetheless, we are patient in this pursuit and intend to make the right acquisition when the opportunity arises. Until an acquisition materializes, we will build cash on our balance sheet and will continue to evaluate all alternative uses of that cash to enhance shareholder value, including stock repurchases and dividends.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

It is our goal to clearly present our financial information in a manner that enhances the understanding of our sources of earnings and cash flows, as well as our financial condition. We do this by including the information required by the SEC, as well as additional information that gives further insight into our financial operations.

Our financial report includes a discussion of our accounting principles, as well as methods and estimates used in the preparation of our financial statements. We believe these discussions and statements fairly represent the financial position and operating results of our company. The purpose of this portion of our discussion is to further emphasize some of the more critical areas where a significant change in facts and circumstances in our operating and financial environment could cause a change in reported financial results.

Intangibles (net of amortization) and Goodwill

We have certain identifiable intangibles, as well as goodwill, amounting to $47 million at year-end 2010 that are discussed in Note 10. These intangibles relate to our petroleum additives business and, except for the goodwill, are being amortized over periods with up to approximately twenty years of remaining life. We continue to assess

37

the market related to these intangibles, as well as their specific values, and have concluded the values and amortization periods are appropriate. We also evaluate these intangibles for any potential impairment when significant events or circumstances occur that might impair the value of these assets. These evaluations continue to support the value at which these identifiable intangibles are carried on our financial statements. In addition, none of our reporting units with goodwill is at risk of failing the goodwill impairment test. However, if conditions were to substantially deteriorate in the petroleum additives market, it could possibly cause a reduction in the periods of this amortization charge or result in a noncash write-off of a portion of the intangibles’ carrying value. A reduction in the amortization period would have no effect on cash flows. We do not anticipate such a change in the market conditions.

Environmental and Legal Proceedings

We have made disclosure of our environmental matters in Item 1 of this Annual Report on Form 10-K, as well as in the Notes to Consolidated Financial Statements. We believe our environmental accruals are appropriate for the exposures and regulatory guidelines under which we currently operate. While we currently do not anticipate significant changes to the many factors that could impact our environmental requirements, we continue to keep our accruals consistent with these requirements as they change.

Also, as noted in the discussion of “Legal Proceedings” in Item 3 of this Annual Report on Form 10-K, while it is not possible to predict or determine with certainty the outcome of any legal proceeding, it is our opinion, based on our current knowledge, that we will not experience any material adverse effects on our results of operations or financial condition as a result of any pending or threatened proceeding.

Pension Plans and Other Postretirement Benefits

We use assumptions to record the impact of the pension and postretirement plans in the financial statements. These assumptions include the discount rate, expected long-term rate of return on plan assets, rate of compensation increase, and health-care cost trend rate. A change in any one of these assumptions could result in different results for the plans. We develop these assumptions after considering available information that we deem relevant. Information is provided on the pension and postretirement plans in Note 19. In addition, further disclosure on the effect of changes in these assumptions is provided in the “Financial Position and Liquidity” section of Item 7.

Income Taxes

We file consolidated U.S. federal and state income tax returns, as well as individual foreign income tax returns, under which assumptions may be made to determine the deductibility of certain costs. We make estimates related to the impact of tax positions taken on our financial statements when we believe the tax position is likely to be upheld on audit. In addition, we make certain assumptions in the determination of the estimated future recovery of deferred tax assets.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to many market risk factors, including fluctuations in interest and foreign currency rates, as well as changes in the cost of raw materials and marketable security prices. These risk factors may affect our results of operations, cash flows, and financial position.

We manage these risks through regular operating and financing methods, including the use of derivative financial instruments. When we have derivative instruments, they are with major financial institutions and are not for speculative or trading purposes. Also, as part of our financial risk management, we regularly review significant contracts for embedded derivatives and record them in accordance with accounting standards.

38

The following analysis presents the effect on our earnings, cash flows, and financial position as if the hypothetical changes in market risk factors occurred at year-end 2010. We analyzed only the potential impacts of our hypothetical assumptions. This analysis does not consider other possible effects that could impact our business.

Interest Rate Risk

At December 31, 2010, we had total debt of $222 million. Of the total debt, $150 million is at fixed rates. There was no interest rate risk at the end of the year associated with the fixed rate debt.

At year-end 2010, we had $4 million of outstanding variable rate debt under our revolving credit facility. Holding all other variables constant, if the variable portion of the interest rate on the revolving credit facility hypothetically increased 10% (approximately 33 basis points), the effect on our earnings and cash flows would have been higher interest expense of approximately $13 thousand.

Substantially, the remaining amount of debt represents the outstanding balance of the mortgage loan, which bears interest at a variable rate of LIBOR plus a margin of 400 basis points. Concurrently with the closing of the mortgage loan, Foundry Park I obtained an interest rate swap to effectively convert the variable interest rate of the loan to a fixed interest rate by setting LIBOR at 2.642% for five years. Accordingly, in combination, there is no interest rate risk associated with the mortgage loan and related interest rate swap, other than the change in the value of the interest rate swap due to changes in the yield curve. The fair value amounted to a liability of $3 million at December 31, 2010. Any change in fair value is recognized immediately in accumulated other comprehensive income, to the degree of effectiveness of the swap. With other variables held constant, a hypothetical 50 basis point adverse parallel shift in the LIBOR yield curve would have resulted in an increase of approximately $1.2 million in the fair value liability of the mortgage loan interest rate swap at December 31, 2010.

We recorded the Goldman Sachs interest rate swap at fair value, which amounted to a liability of $19 million at December 31, 2010. Any change in fair value is recognized immediately in earnings. With other variables held constant, a hypothetical 50 basis point adverse parallel shift in the LIBOR yield curve would have resulted in an increase of approximately $5 million in the liability fair value of the interest rate swap with Goldman Sachs. See Note 16 for further information.

A hypothetical 10% decrease in interest rates, holding all other variables constant, would have resulted in a change of $5 million in fair value of our debt at year-end 2010.

Foreign Currency Risk

We sell to customers in foreign markets through our foreign subsidiaries, as well as through export sales from the United States. These transactions are often denominated in currencies other than the U.S. Dollar. Our primary currency exposures are the European Union Euro, British Pound Sterling, Japanese Yen, and Canadian Dollar. We sometimes enter into forward contracts as hedges to minimize the fluctuation of intercompany accounts receivable denominated in foreign currencies. At December 31, 2010, we had no outstanding forward contracts.

Raw Material Price Risk

We utilize a variety of raw materials in the manufacture of our products, including base oil, polyisobutylene, antioxidants, alcohols, solvents, sulfonates, friction modifiers, olefins and copolymers. Our profitability is sensitive to changes in the costs of these materials caused by changes in supply, demand, or other market conditions, over which we have little or no control. If we experience sudden or sharp increases in the cost of our raw materials, we may not be able to pass on these increases in whole or in part to our customers. Political and economic conditions in the Middle East and Latin America have caused and may continue to cause the cost of our raw materials to fluctuate. War, armed hostilities, terrorist acts, civil unrest or other incidents may also cause a sudden or sharp increase in the cost of our raw materials. If we cannot pass on to our customers any future increases in raw material costs in the form of price increases for our products, there will be a negative impact on operating profit.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of NewMarket Corporation:

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of income, shareholders’ equity and cash flows present fairly, in all material respects, the financial position of NewMarket Corporation and its subsidiaries at December 31, 2010 and 2009, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2010 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2010, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (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 Management’s Report on Internal Control Over Financial Reporting appearing under Item 9A. 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.

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

(tabular amounts in thousands, except per-share amounts)

1. Summary of Significant Accounting Policies

Consolidation—Our consolidated financial statements include the accounts of NewMarket Corporation and its subsidiaries. All significant intercompany transactions are eliminated upon consolidation. References to “we,” “our,” and “NewMarket” are to NewMarket Corporation and its subsidiaries on a consolidated basis, unless the context indicates otherwise.

NewMarket is the parent company of two operating companies, each managing its own assets and liabilities. Those companies are Afton, which focuses on petroleum additive products, and Ethyl, representing certain manufacturing operations and the TEL business. NewMarket is also the parent company of NewMarket Development, which manages the property and improvements that we own in Richmond, Virginia, and NewMarket Services, which provides various administrative services to NewMarket, Afton, Ethyl, and NewMarket Development.

Foreign Currency Translation—We translate the balance sheets of our foreign subsidiaries into U.S. Dollars based on the current exchange rate at the end of each period. We translate the statements of income using the weighted-average exchange rates for the period. NewMarket includes translation adjustments in the balance sheet as part of accumulated other comprehensive loss and transaction adjustments in cost of sales.

Revenue Recognition—Our policy is to recognize revenue from the sale of products when title and risk of loss have transferred to the buyer, the price is fixed and determinable, and collectability is reasonably assured. Provisions for rebates to customers are recorded in the same period the related sales are recorded. Freight costs incurred on the delivery of product are included in cost of goods sold. The majority of our sales are sold FOB (“free on board”) shipping point or on a substantially equivalent basis. Our standard terms of delivery are included in our contracts, sales order confirmation documents, and invoices.

Cash and Cash Equivalents—Our cash equivalents generally consist of government obligations and commercial paper which mature in less than 90 days. Throughout the year, we have cash balances in excess of federally insured amounts on deposit with various financial institutions. We state cash and cash equivalents at cost, which approximates fair value.

At both December 31, 2010 and December 31, 2009, we had a book overdraft for some of our disbursement cash accounts. A book overdraft represents disbursements that have not cleared the bank accounts at the end of the reporting period. We transfer cash on an as-needed basis to fund these items as the items clear the bank in subsequent periods.

Accounts Receivable—We record our accounts receivable at net realizable value. We maintain an allowance for doubtful accounts for estimated losses resulting from our customers not making required payments. We determine the adequacy of the allowance by periodically evaluating each customer’s receivable balance, considering our customers’ financial condition and credit history, and considering current economic conditions.

Inventories—NewMarket values its U.S. petroleum additives and TEL inventories at the lower of cost or market, with cost determined on the last-in, first-out (LIFO) basis. In countries where the LIFO method is not permitted, we use the weighted-average method. Inventory cost includes raw materials, direct labor, and manufacturing overhead.

Property, Plant, and Equipment—We state property, plant, and equipment at cost and compute depreciation by the straight-line method based on the estimated useful lives of the assets. We capitalize expenditures for significant improvements that extend the useful life of the related property. We expense repairs and maintenance,

45

Notes to Consolidated Financial Statements—(Continued)

(tabular amounts in thousands, except per-share amounts)

including plant turnaround costs, as incurred. When property is sold or retired, we remove the cost and accumulated depreciation from the accounts and any related gain or loss is included in earnings.

Our policy on capital leases is to record the asset at the lower of fair value at lease inception or the present value of the total minimum lease payments. We compute amortization by the straight-line method over the lesser of the estimated economic life of the asset or the term of the lease.

Real Estate Development and Construction Costs—We capitalize in property, plant, and equipment the costs associated with real estate development projects, including the cost of land, as well as development and construction costs. We also capitalize interest cost associated with the project. Upon completion of the project, the accumulated depreciable costs are recognized in the Consolidated Statements of Income over the estimated useful life of the asset.

Intangibles (Net of Amortization) and Goodwill—Identifiable intangibles include the cost of acquired contracts; formulas and technology; trademarks and trade name; and customer base. We assign a value to identifiable intangibles based on independent appraisals and internal estimates. NewMarket amortizes the cost of the customer base by an accelerated method and the cost of the remaining identifiable intangibles by the straight-line method over the estimated economic life of the intangible.

Goodwill arises from the excess of cost over net assets of businesses acquired. Goodwill represents the residual purchase price after allocation to all identifiable net assets. We test goodwill for impairment each year and whenever a significant event or circumstance occurs which could reduce the fair value of the reporting unit to which the goodwill applies below the carrying value of the goodwill.

Impairment of Long-Lived Assets—When significant events or circumstances occur that might impair the value of long-lived assets, we evaluate recoverability of the recorded cost of these assets. Assets are considered to be impaired if their carrying value is not recoverable from the estimated undiscounted cash flows associated with the assets. If we determine an asset is impaired and its recorded cost is higher than estimated fair market value based on the estimated present value of future cash flows, we adjust the asset to estimated fair market value.

Asset Retirement Obligations—Asset retirement obligations, including costs associated with the retirement of tangible long-lived assets, are recorded at the fair value of the liability for an asset retirement obligation when incurred instead of ratably over the life of the asset. The asset retirement costs must be capitalized as part of the carrying value of the long-lived asset. If the liability is settled for an amount other than the recorded balance, we recognize either a gain or loss at settlement.

Environmental Costs—NewMarket capitalizes environmental compliance costs if they extend the useful life of the related property or prevent future contamination. Environmental compliance costs also include maintenance and operation of pollution prevention and control facilities. We expense these compliance costs as incurred.

Accrued environmental remediation and monitoring costs relate to an existing condition caused by past operations. NewMarket accrues these costs in current operations within cost of goods sold in the Consolidated Statements of Income when it is probable that we have incurred a liability and the amount can be reasonably estimated.

When we can reliably determine the amount and timing of future cash flows, we discount these liabilities, incorporating an inflation factor.

46

Notes to Consolidated Financial Statements—(Continued)

(tabular amounts in thousands, except per-share amounts)

Employee Savings Plan—Most of our full-time salaried and hourly employees may participate in defined contribution savings plans. Employees who are covered by collective bargaining agreements may also participate in a savings plan according to the terms of their bargaining agreements. Employees, as well as NewMarket, contribute to the plans. We made contributions of $4 million in 2010 and $3 million in both 2009 and 2008 related to these plans.

Research, Development, and Testing Expenses—NewMarket expenses all research, development, and testing costs as incurred. Of the total research, development, and testing expenses, those related to new products and processes were $45 million in 2010, $46 million in 2009, and $44 million in 2008.

Income Taxes—We recognize deferred income taxes for temporary differences between the financial reporting basis and the income tax basis of assets and liabilities. We also adjust for changes in tax rates and laws at the time the changes are enacted. A valuation allowance is recorded when it is more likely than not that a deferred tax asset will not be realized. We recognize accrued interest and penalties associated with uncertain tax positions as part of income tax expense on our Consolidated Statements of Income.

We generally provide for additional U.S. taxes that would be incurred when a foreign subsidiary returns its earnings in cash to Afton or Ethyl. Undistributed earnings of certain foreign subsidiaries for which U.S. taxes have not been provided totaled approximately $138 million at December 31, 2010, $92 million at December 31, 2009, and $67 million at December 31, 2008. Deferred income taxes have not been provided on these earnings since we expect them to be indefinitely reinvested abroad. Accordingly, no provision has been made for taxes that may be payable on the remittance of these earnings at December 31, 2010 or December 31, 2009. The determination of the amount of such unrecognized deferred tax liability is not practicable.

Derivative Financial Instruments and Hedging Activities—We record all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether we have elected to designate a derivative in a hedging relationship and apply hedge accounting, and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. We may enter into derivative contracts that are intended to economically hedge certain of our risks, even though hedge accounting does not apply or we elect not to apply hedge accounting. We do not enter into derivative instruments for speculative purposes. Additional information on our derivatives and hedging activities is in Note 16.

Stock-Based Compensation—We use an option-pricing model similar to Black-Scholes to estimate the fair value of options and recognize the related costs in the financial statements. See Note 15 for further information on our stock-based compensation plan.

Investments—We classify current marketable securities as “available for sale” and record them at fair value with the unrealized gains or losses, net of tax, included as a component of shareholders’ equity in accumulated other comprehensive loss. The fair value is determined based on quoted market prices.

When a decline in the fair value of a marketable security is considered other than temporary, we writedown the investment to estimated fair market value with a corresponding charge to earnings.

Estimates and Risks Due to Concentration of Business—The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

47

Notes to Consolidated Financial Statements—(Continued)

(tabular amounts in thousands, except per-share amounts)

In addition, our financial results can be influenced by certain risk factors. Some of our significant concentrations of risk include the following:

• reliance on a small number of significant customers;

• customers concentrated in the fuel and lubricant industries;

• production of several of our products solely at one facility; and

• cash balances in excess of federally insured amounts on deposit with various financial institutions.

2. Acquisition of Business

On March 5, 2010, Afton Chemical Corporation completed the acquisition of 100% of Polartech for $43.1 million in cash. Polartech is a global company specializing in the supply of metalworking additives. The acquisition agreement included all physical assets of the Polartech business including the headquarters, research and development, and manufacturing facilities in the United Kingdom, as well as manufacturing sites in India, China, and the United States.

We performed a valuation of the assets acquired to determine the purchase price allocation. This valuation resulted in the recognition of $6 million of identifiable intangibles, including formulas and technology, customer base, and trademarks/trade names. We also acquired property, plant, and equipment of $28.4 million, as well as working capital.

As part of the acquisition, we recorded $4.2 million of goodwill. The goodwill resulted from the cost of assets acquired exceeding the valuation of the assets and liabilities. All of the goodwill recognized is part of the petroleum additives segment, and none is deductible for tax purposes.

Pro forma consolidated results of operations for the year ended December 31, 2010, December 31, 2009, and December 31, 2008, assuming the acquisition had occurred on January 1, 2010, January 1, 2009, or January 1, 2008, would not be materially different from the actual results reported for NewMarket Corporation for the year ended December 31, 2010, December 31, 2009, and December 31, 2008.

There were no bad debt write-offs in either 2010 or 2009. Bad debt expense was $54 thousand in 2008. The allowance for doubtful accounts amounted to $1.1 million at December 31, 2008. The change in the allowance for doubtful accounts between 2009 and 2010 primarily reflects our evaluation of certain higher risk customer receivables, all of which are current at December 31, 2010, as well as allowances for disputed invoiced prices and quantities. The change in the allowance doubtful accounts between 2008 and 2009 reflects allowances for disputed invoiced prices and quantities.

The reserve for obsolete and slow moving inventory amounted to $3 million at December 31, 2010 and $800 thousand at December 31, 2009. These amounts are included in the table above.

Our foreign inventories amounted to $178 million at year-end 2010 and $126 million at year-end 2009.

Our U.S. inventories, which are stated on the LIFO basis, amounted to $83 million at year-end 2010, which was below replacement cost by approximately $49 million. At year-end 2009, LIFO basis inventories were $58 million, which was approximately $41 million below replacement cost.

During 2010, the TEL inventory quantities were reduced resulting in a liquidation of LIFO layers. The effect of this liquidation increased net income by $200 thousand in 2010. During 2009, the petroleum additives and TEL inventory quantities were reduced resulting in a liquidation of LIFO layers. The effect of these liquidations increased net income $400 thousand with $300 thousand from petroleum additives and $100 thousand from TEL.

We depreciate the cost of property, plant, and equipment generally by the straight-line method and primarily over the following useful lives:

Land improvements	5 - 30 years
Buildings	10 - 50 years
Machinery and equipment	3 - 15 years

At both December 31, 2010 and December 31, 2009, assets held for lease and included in the table above, include $3 million of land, $2 million of land improvements, $66 million of buildings, and $38 million of machinery and equipment. Accumulated depreciation on these assets was $4 million at December 31, 2010. There was no accumulated depreciation at December 31, 2009. All of these assets represent the assets of Foundry Park I.

Interest capitalized was $400 thousand in 2010, $2.0 million in 2009, and $1.7 million in 2008. Of the total amount capitalized, $1.5 million in 2009 and $1.1 million in 2008 related to the construction of the office building by Foundry Park I. Capitalized interest is amortized generally over the same lives as the asset to which it relates. Depreciation expense was $29 million in 2010, $23 million in 2009, and $21 million in 2008. Amortization of capitalized interest, which is included in depreciation expense, was $300 thousand in 2010 and $200 thousand in both 2009 and 2008.

We incurred $4 million of additional deferred financing fees in 2010 related to the mortgage loan and the new senior credit facility, and recognized amortization expense of $1 million during 2010. The accumulated amortization on the deferred financing costs relating to our 7.125% senior notes, mortgage loan, and current senior credit facility was $2 million at December 31, 2010 and $6 million at December 31, 2009. In addition to

The increase in 2010 in gross amortizing intangible assets and goodwill reflected above was the result of the purchase of Polartech. See Note 2 for further information on the acquisition of Polartech.

The goodwill in 2009 relates to the 2008 acquisition by Afton of the North American Fuel Additives Business from GE Water and Process Technologies for $15 million, which was paid upon acquisition. We performed a valuation of the assets acquired to determine the purchase price allocation. The results of the valuation resulted in the recognition of $14 million of identifiable intangibles, including contracts, formulas, and customer base, as well as the goodwill of approximately $900 thousand.

During 2006 we acquired contracts with a value of approximately $10 million. We paid approximately $1 million during each of 2010, 2009, and 2008, as well as $3 million during 2007 and $4 million during 2006 for the acquisition of these 2006 contracts. We recorded the remaining amount payable under the contracts as a liability at December 31, 2009. There was no remaining amount payable at December 31, 2010.

The fair value of intangible assets is estimated based upon management’s assessment, as well as independent third-party appraisals, in some cases. All of the intangibles relate to the petroleum additives segment. There is no accumulated goodwill impairment.

Estimated amortization expense for the next five years is expected to be:

•   2011	$	8,586
•   2012	$	7,421
•   2013	$	7,108
•   2014	$	6,163
•   2015	$	5,790

52

Notes to Consolidated Financial Statements—(Continued)

(tabular amounts in thousands, except per-share amounts)

Generally, we amortize the cost of the customer base intangible by an accelerated method and the cost of the remaining intangible assets by the straight-line method over their estimated economic lives. We generally amortize contracts over 1.5 to 10 years and formulas and technology over 5 to 20 years. Trademarks and the trade name are amortized over 10 years.

	$	217,544		$	216,200

Senior Notes—The 7.125% senior notes are our senior unsecured obligations and are jointly and severally guaranteed on an unsecured basis by all of our existing and future wholly-owned domestic restricted subsidiaries. We incurred financing costs of approximately $3 million in 2006 related to the 7.125% senior notes, which are being amortized over ten years.

The 7.125% senior notes and the subsidiary guarantees rank:

• effectively junior to all of our and the guarantors’ existing and future secured indebtedness, including any borrowings under the senior credit facility described below;

• equal in right of payment with any of our and the guarantors’ existing and future unsecured senior indebtedness; and

• senior in right of payment to any of our and the guarantors’ existing and future subordinated indebtedness.

53

Notes to Consolidated Financial Statements—(Continued)

(tabular amounts in thousands, except per-share amounts)

The indenture governing the 7.125% senior notes contains covenants that, among other things, limit our ability and the ability of our restricted subsidiaries to:

• incur additional indebtedness;

• create liens;

• pay dividends or repurchase capital stock;

• make certain investments;

• sell assets or consolidate or merge with or into other companies; and

• engage in transactions with affiliates.

The more restrictive and significant of the covenants under the indenture include a minimum fixed charge ratio of 2.00, as well as a limitation on restricted payments, as defined in the indenture.

We were in compliance with all covenants under the indenture governing the 7.125% senior notes as of December 31, 2010 and December 31, 2009.

Senior Credit Facility—On November 12, 2010, we entered into a Credit Agreement (Credit Agreement). The Credit Agreement provides for a $300 million, multicurrency revolving credit facility, with a $100 million sublimit for multicurrency borrowings, a $100 million sublimit for letters of credit, and a $20 million sublimit for swingline loans. The Credit Agreement includes an expansion feature, which allows us, subject to certain conditions, to request to increase the aggregate amount of the revolving credit facility or obtain incremental term loans in an amount up to $150 million. We used the proceeds from the Credit Agreement to pay off the outstanding balance of $35 million on our previous revolving credit agreement. Our previous revolving credit agreement was terminated on November 12, 2010.

At December 31, 2010, we had outstanding letters of credit of $5.1 million and borrowings of $4 million, resulting in the unused portion of the senior credit facility amounting to $290.9 million. For further information on the outstanding letters of credit, see Note 18.

We paid financing costs in 2010 of approximately $2.5 million related to this agreement and carried over deferred financing costs from our previous revolving credit agreement of approximately $700 thousand, resulting in total deferred financing costs of $3.2 million, which we are amortizing over the term of the Credit Agreement.

The obligations under the Credit Agreement are unsecured and are fully and unconditionally guaranteed by NewMarket and the subsidiary guarantors. The revolving credit facility matures on November 12, 2015.

Borrowing made under the revolving credit facility bear interest at an annual rate equal to, at our election, either (1) the ABR plus the Applicable Rate (solely in the case of loans denominated in U.S. dollars to NewMarket) or (2) the Adjusted LIBO Rate plus the Applicable Rate. ABR is the greatest of (i) the rate of interest publicly announced by the Administrative Agent as its prime rate, (ii) the federal funds effective rate from time to time plus 0.5% or (iii) the Adjusted LIBO Rate for a one month interest period plus 1%. The Adjusted LIBO Rate means the rate at which Eurocurrency deposits in the London interbank market for certain periods (as selected by NewMarket) are quoted, as adjusted for statutory reserve requirements for Eurocurrency liabilities and other applicable mandatory costs. Depending on our Leverage Ratio, the Applicable Rate ranges from 1.00% to 1.50% for loans bearing interest based on the ABR and from 2.00% to 2.50% for loans bearing interest based on the Adjusted LIBO Rate. At December 31, 2010, the Applicable Rate was 1.00% for loans bearing interest based on

54

Notes to Consolidated Financial Statements—(Continued)

(tabular amounts in thousands, except per-share amounts)

the ABR and 2.00% for loans bearing interest based on the Adjusted LIBO Rate. Our average interest rate under the current revolving credit agreement was 3.6% during 2010, while the combined average interest rate under both revolving credit agreements in effect during 2010 was 4.5%. At December 31, 2010, the interest rate was 4.25%.

The Credit Agreement contains financial covenants that require NewMarket to maintain a consolidated Leverage Ratio (as defined in the Credit Agreement) of no more than 3.00 to 1.00 and a consolidated Interest Coverage ratio (as defined in the Credit Agreement) of no less than 3.00 to 1.00, as of the end of each fiscal quarter ending on and after December 31, 2010.

We were in compliance with all covenants under the Credit Agreement at December 31, 2010.

Mortgage Loan Agreement—On January 28, 2010, Foundry Park I entered into a mortgage loan agreement in the amount of $68.4 million. The loan, which is collateralized by the Foundry Park I office building, is for a period of five years, with two thirteen-month extension options. NewMarket Corporation is fully guaranteeing the loan. The mortgage loan bears interest at a variable rate of LIBOR plus a margin of 400 basis points, with a minimum LIBOR of 200 basis points. At December 31, 2010, the interest rate was 4.26%. Principal payments on the loan are being made monthly based on a 15 year amortization schedule, with all remaining amounts due in five years, unless we exercise the extension options. We incurred financing costs of $1.5 million related to the mortgage loan, which are being amortized over five years.

Concurrently with the closing of the mortgage loan, Foundry Park I obtained an interest rate swap to effectively convert the variable interest rate in the loan to a fixed interest rate by setting LIBOR at 2.642% for five years. Further information on the interest rate swap is in Note 16.

Construction Loan Agreement—Foundry Park I and NewMarket Corporation entered into a construction loan agreement with a group of banks on August 7, 2007 to borrow up to $116 million to fund the development and construction of an office building. The construction loan bore interest at LIBOR plus a margin of 140 basis points. The term of the loan was for a period of 36 months and was unconditionally guaranteed by NewMarket Corporation. No principal reduction payment became due during the construction period. As a condition of the construction loan and concurrently with the closing of the loan, Foundry Park I also obtained interest rate risk protection in the form of an interest rate swap. See Note 16. On January 29, 2010, we paid off the outstanding balance of $99.1 million of the construction loan with proceeds of $68.4 million from the mortgage loan agreement (discussed above) and cash on hand of $30.7 million.

Other Borrowings—One of our subsidiaries in India has a short-term line of credit of 110 million Rupees for working capital purposes. The average interest rate was approximately 9.8% during 2010 and 9.96% at December 31, 2010. The outstanding balance of $1.5 million at December 31, 2010 is due during 2011.

We record our capital lease obligations at the lower of fair market value of the related asset at the inception of the lease or the present value of the total minimum lease payments. Capital lease obligations, including interest, will be approximately $100 thousand for 2011. The future minimum lease payments in excess of the capital lease obligation are included in the noncancelable future lease payments discussed in Note 18.

15. Stock-Based Compensation

The 2004 Incentive Compensation and Stock Plan (the Plan) was approved on May 24, 2004. Any employee of our company or an affiliate or a person who is a member of our board of directors or the board of directors of an affiliate is eligible to participate in the Plan if the Compensation Committee of the Board of Directors (the

56

Notes to Consolidated Financial Statements—(Continued)

(tabular amounts in thousands, except per-share amounts)

Administrator), in its sole discretion, determines that such person has contributed significantly or can be expected to contribute significantly to the profits or growth of our company or its affiliates (each, a participant). Under the terms of the Plan, we may grant participants stock awards, incentive awards, or options (which may be either incentive stock options or nonqualified stock options), or stock appreciation rights (SARs), which may be granted with a related option. Stock options entitle the participant to purchase a specified number of shares of our common stock at a price that is fixed by the Administrator at the time the option is granted; provided, however, that the price cannot be less than the shares’ fair market value on the date of grant. The maximum period in which an option may be exercised is fixed by the Administrator at the time the option is granted but, in the case of an incentive stock option, cannot exceed ten years.

The maximum aggregate number of shares of our common stock that may be issued under the Plan is 1,500,000. During 2010, 17,053 shares of our common stock were issued under the Plan resulting in 1,477,595 shares being available for grant at December 31, 2010. No participant may be granted or awarded in any calendar year options or SARs covering more than 200,000 shares of our common stock in the aggregate. For purposes of this limitation and the individual limitation on the grant of options, an option and corresponding SAR are treated as a single award.

Of the 17,053 shares of common stock issued during 2010 under the Plan, 1,374 shares were to six of our non-employee directors with an aggregate fair value of $120 thousand at the issue date of July 1, 2010. The fair value of the shares was based on the closing price of our common stock on the day prior to the date of issue. We recognized expense of $120 thousand related to the issuance of this common stock. The remaining 15,679 shares issued during 2010 under the Plan related to a stock award granted on November 15, 2010. The shares issued under award vested immediately; however, the stock may not be sold or otherwise transferred until November 15, 2011. We recognized expense of $2.8 million related to the issuance of the shares under the stock award.

At December 31, 2010, we had 16,000 outstanding options to purchase shares of our common stock at an exercise price of $4.35 per share. These outstanding options became exercisable over a stated period of time. These previously granted outstanding options were awarded under Ethyl’s 1982 Stock Option Plan, which terminated in March 2004, and pursuant to which no further options may be granted. None of these options include an associated SAR. These options are fully vested and exercisable at December 31, 2010. All of the outstanding options will expire on September 28, 2011.

A summary of activity during 2010 in NewMarket’s stock option plan is presented below in whole shares:

	Whole Shares			Weighted Average Exercise Price		Weighted Average Remaining Contractual Term in Years		Aggregate Intrinsic Value (in  thousands)
Outstanding at January 1, 2010		37,000		$	4.35
Exercised		(21,000	)		4.35			$	2,345
Outstanding at December 31, 2010		16,000		$	4.35		0.74	$	1,904
Exercisable at December 31, 2010		16,000		$	4.35		0.74	$	1,904

We have neither granted nor modified any stock option awards in 2010, 2009, or 2008. The total intrinsic value of options exercised was $2 million for 2010, $500 thousand for 2009, and $4 million for 2008.

57

Notes to Consolidated Financial Statements—(Continued)

(tabular amounts in thousands, except per-share amounts)

We recognized a tax benefit of $700 thousand on the $4.35 options for 2010 and $1 million for 2008. We recognized no tax benefit for 2009. There was no unrecognized compensation cost during 2010, 2009, or 2008.

16. Derivatives and Hedging Activities

Accounting Policy for Derivative Instruments and Hedging Activities

Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Derivatives may also be designated as hedges of the foreign currency exposure of a net investment in a foreign operation. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge.

Risk Management Objective of Using Derivatives

We are exposed to certain risks arising from both our business operations and economic conditions. We primarily manage our exposures to a wide variety of business and operational risks through management of our core business activities.

We manage certain economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of our debt funding, as well as through the use of derivative financial instruments. Specifically, we have entered into interest rate swaps to manage our exposure to interest rate movements.

Our foreign operations expose us to fluctuations of foreign exchange rates. These fluctuations may impact the value of our cash receipts and payments as compared to our reporting currency, the U.S. Dollar. To manage this exposure, we sometimes enter into foreign currency forward contracts to minimize currency exposure due to cash flows from foreign operations.

Cash Flow Hedge of Interest Rate Risk

In January 2010, we entered into an interest rate swap to manage our exposure to interest rate movements on the Foundry Park I mortgage loan and to reduce variability in interest expense. Further information on the mortgage loan is in Note 12. We also had an interest rate swap to manage our exposure to interest rate movements on the Foundry Park I construction loan and add stability to capitalized interest expense. The Foundry Park I construction loan interest rate swap matured on January 1, 2010. Further information on the construction loan is in Note 12. Both interest rate swaps are designated and qualify as a cash flow hedge. As such, the effective portion of changes in the fair value of the swaps is recorded in accumulated other comprehensive loss and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. Any ineffective portion of changes in the fair value of the swap is recognized immediately in earnings. We assess the effectiveness of the mortgage loan interest rate swap quarterly, just as we assessed the effectiveness of the construction loan interest rate swap quarterly, by comparing the changes in the fair value of the derivative hedging instrument with the change in present value of the expected future cash flows of the hedged transaction.

Both interest rate swaps involve the receipt of variable-rate amounts based on LIBOR in exchange for fixed-rate payments over the life of the agreement without exchange of the underlying notional amount. The fixed-rate payments are at a rate of 2.642% for the mortgage loan interest rate swap, while the fixed-rate payments on the

58

Notes to Consolidated Financial Statements—(Continued)

(tabular amounts in thousands, except per-share amounts)

construction loan interest rate swap were at a rate of 4.975%. The notional amount of the mortgage loan interest rate swap was $68 million at origination and approximately $66 million at December 31, 2010. The notional amount of the mortgage loan swap amortizes to approximately $54 million over the term of the swap. The amortizing notional amount is necessary to maintain the swap notional at an amount that matches the declining mortgage loan principal balance over the loan term. The mortgage loan interest swap matures on January 29, 2015. The notional amount of the construction loan interest rate swap was approximately $94 million at December 31, 2009, just prior to its January 1, 2010 maturity. The accreting notional amount was necessary to maintain the construction loan interest rate swap notional at an amount that represented approximately 85% of the projected construction loan principal balance over the loan term.

The unrealized loss, net of tax, related to the fair value of the mortgage loan interest rate swap is recorded in accumulated other comprehensive loss in shareholders’ equity on the Consolidated Balance Sheets, and amounted to approximately $1.5 million at December 31, 2010. The unrealized loss, net of tax, related to the fair value of the construction loan interest rate swap and recorded in accumulated other comprehensive loss amounted to approximately $37 thousand at December 31, 2009. This amount was settled on January 1, 2010. Also recorded as a component of accumulated other comprehensive loss in shareholders’ equity on the Consolidated Balance Sheets was the accumulated losses related to the construction loan interest rate swap. This amounted to approximately $3 million, net of tax, at both December 31, 2010 and December 31, 2009. The amounts remaining in accumulated other comprehensive loss related to the construction loan interest rate swap are being recognized in the Consolidated Statements of Income over the depreciable life of the office building beginning in January 2010. Approximately $1 million, net of tax, currently recognized in accumulated other comprehensive loss related to both the construction loan interest rate swap and the mortgage loan interest rate swap is expected to be reclassified into earnings over the next twelve months.

Non-designated Hedges

On June 25, 2009, we entered into an interest rate swap with Goldman Sachs in the notional amount of $97 million and with a maturity date of January 19, 2022 (Goldman Sachs interest rate swap). NewMarket entered into the Goldman Sachs interest rate swap in connection with the termination of a loan application and related rate lock agreement between Foundry Park I and Principal. When the rate lock agreement was originally executed in 2007, Principal simultaneously entered into an interest rate swap with a third party to hedge Principal’s exposure to fluctuation in the ten-year Treasuries rate. Upon the termination on June 25, 2009 of the rate lock agreement, Goldman Sachs both assumed Principal’s position with the third party and entered into an offsetting interest rate swap with NewMarket. Under the terms of this interest rate swap, NewMarket is making fixed rate payments at 5.3075% and Goldman Sachs will make variable rate payments based on three-month LIBOR. We have collateralized this exposure through cash deposits posted with Goldman Sachs amounting to $23 million at December 31, 2010. This transaction effectively preserves the impact of the original rate lock agreement for the possible application to a future loan amount of $97 million of a similar structure.

In December 2008, we entered into $17 million of Euro-denominated forward contracts to minimize foreign currency exposure from expected cash flows from foreign operations. The forward contracts obligated us to sell Euros for U.S. Dollars at a fixed exchange rate of 1.403, which was agreed to at the inception of the contracts. These contracts had maturity dates through December 2009. The outstanding Euro-denominated foreign currency forward contracts amounted to $17 million at December 31, 2008. There were no outstanding contracts at December 31, 2010 or December 31, 2009.

In April 2008, we entered into $11 million of Euro-denominated forward contracts. The contracts all matured in 2008.

(tabular amounts in thousands, except per-share amounts)

During 2007, we entered into $16 million of Euro-denominated forward contracts. The contracts had maturity dates from June 2007 to May 2008.

Any foreign currency rate change that affects the fair value of any of these forward contract transactions was offset by a corresponding change in the value of the Euro-denominated transactions.

We elected not to use hedge accounting for both the Goldman Sachs interest rate swap and the forward contracts, and therefore, immediately recognize any change in the fair value of these derivative financial instruments directly in earnings.

The table below presents the fair value of our derivative financial instruments, as well as their classification on the Consolidated Balance Sheets as of December 31, 2010 and December 31, 2009.

Credit-risk-related Contingent Features

We have agreements with both of our current derivative counterparties that contain a provision where we could be declared in default on our derivative obligations if repayment of indebtedness is accelerated by the lender due to our default on the indebtedness.

Notes to Consolidated Financial Statements—(Continued)

(tabular amounts in thousands, except per-share amounts)

As of December 31, 2010, the fair value of derivatives in a net liability position, which includes accrued interest but excludes any adjustment for nonperformance risk, related to these agreements was $21 million. We have minimum collateral posting thresholds with one of our derivative counterparties and have posted cash collateral of $23 million as of December 31, 2010. If required, we could have settled our obligations under the agreements at their termination value of $21 million at December 31, 2010.

17. Fair Value Measurements

The following table provides information on assets and liabilities measured at fair value on a recurring basis. No events occurred during the twelve months ended December 31, 2010, requiring adjustment to the recognized balances of assets or liabilities which are recorded at fair value on a nonrecurring basis.

	Carrying Amount in Consolidated Balance Sheets		Fair Value		Fair Value Measurements Using
					Level 1		Level 2		Level 3
	December 31, 2010
Cash and cash equivalents	$	49,192	$	49,192	$	49,192	$	0	$	0
Short-term investments	$	300	$	300	$	300	$	0	$	0

Interest rate swaps liability	$	11,861	$	11,861	$	0	$	11,861	$	0

We determine the fair value of the derivative instruments shown in the table above by using widely-accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each instrument. The analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs.

The fair value of the interest rate swaps is determined using the market standard methodology of netting the discounted future fixed cash receipts and the discounted expected variable cash payments. The variable cash payments are based on an expectation of future interest rates derived from observable market interest rate curves. In determining the fair value measurements, we incorporate credit valuation adjustments to appropriately reflect both our nonperformance risk and the counterparties’ nonperformance risk.

Although we have determined that the majority of the inputs used to value our derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustment associated with the derivatives utilizes Level 3 inputs. These Level 3 inputs include estimates of current credit spreads to evaluate the likelihood of default by both us and the counterparties to the derivatives. As of December 31, 2010 and December 31, 2009, we have assessed the significance of the impact of the credit valuation adjustment on the overall valuation of our derivatives and have determined that the credit valuation adjustment is not significant to the overall valuation of the derivatives. Accordingly, we have determined that our derivative valuations should be classified in Level 2 of the fair value hierarchy.

Long-Term Debt—We record the value of our long-term debt at historical cost. The estimated fair value of our long-term debt is shown in the table below and is based primarily on estimated current rates available to us for debt of the same remaining duration and adjusted for nonperformance risk and credit risk.

18. Contractual Commitments and Contingencies

Contractual Commitments—NewMarket has operating lease agreements primarily for office space, transportation equipment, and storage facilities. Rental expense was $22 million in 2010, $19 million in 2009, and $20 million in 2008.

Future lease payments for all noncancelable operating leases as of December 31, 2010 are:

•   2011	$	10 million
•   2012	$	6 million
•   2013	$	5 million
•   2014	$	4 million
•   2015	$	3 million
•   After 2015	$	16 million

Future minimum lease payments in excess of the capital lease debt obligation as of December 31, 2010 amount to approximately $100 thousand for 2011. We have contractual obligations for the construction of assets, as well as purchases of property and equipment of approximately $7 million at December 31, 2010.

Raw Material Purchase Obligations—We have raw material purchase obligations over the next five years amounting to approximately $273 million at December 31, 2010 for agreements to purchase goods or services that are enforceable, and legally binding and that specify all significant terms, including: fixed or minimum quantities to be purchased; fixed, minimum, or variable price provisions; and the approximate timing of the transaction. Raw material purchase obligations exclude agreements that are cancelable without penalty. Purchase orders made in the ordinary course of business are excluded from this amount. Any amounts for which we are liable under purchase orders are reflected in our Consolidated Balance Sheets as accounts payable and accrued expenses.

Litigation—We are involved in legal proceedings that are incidental to our business and include administrative or judicial actions seeking remediation under environmental laws, such as Superfund. Some of these legal proceedings relate to environmental matters and involve governmental authorities. For further information see “Environmental” below and Item 3.

While it is not possible to predict or determine with certainty the outcome of any legal proceeding, we believe the outcome of any of these proceedings, or all of them combined, will not result in a material adverse effect on our financial condition or results of operations.

On July 23, 2010, Afton Chemical Corporation and NewMarket Corporation filed a complaint in Federal District Court in Richmond, Virginia against Innospec. The complaint alleges that Innospec violated the Robinson-Patman Act, the Sherman Act, the Virginia Antitrust Act and Virginia Business Conspiracy Act based on the disclosures that Innospec recently made in its plea agreements with the U.S. Department of Justice and the Securities and Exchange Commission, as well as the UK Serious Fraud Office. In those agreements, Innospec pled guilty to violating the Foreign Corrupt Practices Act by bribing government officials in Iraq and Indonesia. Innospec paid the bribes to secure the sale of its product and to exclude NewMarket’s product in Iraq

and Indonesia. Afton Chemical Corporation and NewMarket Corporation are seeking treble damages, all reasonable attorneys’ fees, expenses, and costs for injuries sustained as a result of these bribes.

Asbestos

We are a defendant in personal injury lawsuits involving exposure to asbestos. These cases involve exposure to asbestos in premises owned or operated, or formerly owned or operated, by subsidiaries of NewMarket. We have never manufactured, sold, or distributed products that contain asbestos. Nearly all of these cases are pending in Texas, Louisiana, or Illinois and involve multiple defendants. We maintain an accrual for these proceedings, as well as a receivable for expected insurance recoveries.

During 2005, we entered into an agreement with Travelers Indemnity Company resolving certain long-standing issues regarding our coverage for certain premises asbestos claims. In addition, our agreement with Travelers provides a procedure for allocating defense and indemnity costs with respect to certain future premises asbestos claims. The lawsuit we had previously filed against Travelers in the Southern District of Texas was dismissed. We also settled our outstanding receivable from Albemarle Corporation for certain premises asbestos liability obligations.

The accrual for our premises asbestos liability related to currently asserted claims is based on the following assumptions and factors:

• We are often one of many defendants. This factor influences both the number of claims settled against us and also the indemnity cost associated with such resolutions.

• The estimated percent of claimants in each case that will actually, after discovery, make a claim against us, out of the total number of claimants in a case, is based on a level consistent with past experience and current trends.

• We utilize average comparable plaintiff cost history as the basis for estimating pending premises asbestos related claims. These claims are filed by both former contractors’ employees and former employees who worked at past and present company locations. We also include an estimated inflation factor in the calculation.

• No estimate is made for unasserted claims.

• The estimated recoveries from insurance and Albemarle Corporation for these cases are based on, and are consistent with, the 2005 settlement agreements.

Based on the above assumptions, we have provided an undiscounted liability related to premises asbestos claims of $13.6 million at both year-end 2010 and year-end 2009. The liabilities related to asbestos claims are included in accrued expenses (current portion) and other noncurrent liabilities on the balance sheet. Certain of these costs are recoverable through our insurance coverage and agreement with Albemarle Corporation. The receivable for these recoveries related to premises asbestos liabilities was $9.6 million at December 31, 2010 and $9.8 million at December 31, 2009. These receivables are included in trade and other accounts receivable, net for the current portion. The noncurrent portion is included in other assets and deferred charges.

Environmental—During 2000, the EPA named us as a PRP under Superfund law for the clean-up of soil and groundwater contamination at the Sauget Area 2 Site in Sauget, Illinois. Without admitting any fact, responsibility, fault, or liability in connection with this site, we are participating with other PRPs in site investigations and feasibility studies. The Sauget Area 2 Site PRPs received notice of approval from the EPA of their October 2009 Human Health Risk Assessment. Additionally, the PRPs have submitted their Feasibility

(tabular amounts in thousands, except per-share amounts)

Study (FS) to the EPA Remedy review board. We have accrued our estimated proportional share of the expenses for the FS, as well as our best estimate of our proportional share of the remediation liability proposed in our ongoing discussions and submissions with the agencies involved. We do not believe there is any additional information available as a basis for revision of the liability that we have established. The amount accrued for this site is not material.

At a former TEL plant site located in the state of Louisiana, we have completed significant environmental remediation, although we will be monitoring and treating the site for an extended period. The accrual for this site was $6.8 million at year-end 2010 and $7.5 million at year-end 2009. We based these amounts on the best estimate of future costs discounted at approximately 3% in both 2010 and 2009. An inflation factor is included in the estimate. The undiscounted liability was $8.7 million at year-end 2010 and $9.7 million at year-end 2009. The expected payments for each of the next five years amount to approximately $800 thousand in 2011, $700 thousand in 2012, and $600 thousand for each of the years 2013 through 2015. Expected payments thereafter amount to approximately $5.4 million.

At a plant site in Houston, Texas, we have an accrual of $7.6 million at December 31, 2010 and $7.9 million at December 31, 2009 for environmental remediation, dismantling, and decontamination. Included in these amounts are $7.3 million at year-end 2010 and $7.6 million at year-end 2009 for remediation. Of the total remediation, $6.9 million at December 31, 2010 and $7.2 million at December 31, 2009 relates to remediation of groundwater and soil. The accruals for this site are discounted at approximately 3% at December 31, 2010 and December 31, 2009. The accruals include an inflation factor. The undiscounted accrual for this site was $10.8 million at year-end 2010 and $11.2 million at year-end 2009. The expected payments for each of the next five years are approximately $400 thousand in 2011, $500 thousand in 2012, $600 thousand in 2013, $1.6 million in 2014, and $200 thousand in 2015. Expected payments thereafter amount to approximately $7.5 million.

At a superfund site in Louisiana, we have an accrual of $3.3 million at December 31, 2010 and $2.6 million at December 31, 2009 for environmental remediation. The accrual for this site was discounted at approximately 3% and included an inflation factor. The undiscounted accrual for this site was $4.2 million at December 31, 2010 and $3.2 million at December 31, 2009. The expected payments over the next five years amount to approximately $500 thousand in 2011, $400 thousand in 2012, and $200 thousand each for years 2013 through 2015. Expected payments thereafter amount to approximately $2.7 million.

The remaining environmental liabilities are not discounted.

We accrue for environmental remediation and monitoring activities for which costs can be reasonably estimated and are probable. These estimates are based on an assessment of the site, available clean-up methods, and prior experience in handling remediation. While we believe we are currently fully accrued for known environmental issues, it is possible that unexpected future costs could have a significant impact on our financial position and results of operations.

At December 31, our total accruals for environmental remediation were $22.5 million for 2010 and $22.0 million for 2009. In addition to the accruals for environmental remediation, we also have accruals for dismantling and decommissioning costs of $500 thousand at both December 31, 2010 and December 31, 2009

NewMarket spent $18 million in 2010 and $17 million in both 2009 and 2008 for ongoing environmental operating and clean-up costs, excluding depreciation of previously capitalized expenditures. On capital expenditures for pollution prevention and safety projects, we spent $7 million in 2010, $5 million in 2009, and $7 million in 2008.

(tabular amounts in thousands, except per-share amounts)

Letters of Credit and Guarantees—We have outstanding guarantees with several financial institutions in the amount of $41.6 million at December 31, 2010. The guarantees are secured by letters of credit, as well as cash collateral. A portion of these guarantees is unsecured. The outstanding letters of credit amounted to $5.1 million at December 31, 2010, all of which were issued under the letter of credit sub-facility of our revolving credit facility. See Note 12. The letters of credit primarily relate to insurance guarantees. We renew letters of credit as necessary. The remaining amounts represent performance, lease, custom and excise tax guarantees, as well as a cash deposit of $23 million related to the Goldman Sachs interest rate swap. The cash deposit is recorded in “Other assets and deferred charges” on the Consolidated Balance Sheet. See Note 9 for further information. Expiration dates range from 2011 to 2013. Some of the guarantees have no expiration date.

We cannot estimate the maximum amount of potential liability under the guarantees. However, we accrue for potential liabilities when a future payment is probable and the range of loss can be reasonably estimated.

19. Pension Plans and Other Postretirement Benefits

NewMarket uses a December 31 measurement date for all of our plans.

U.S. Retirement Plans

NewMarket sponsors pension plans for all full-time U.S. employees that offer a benefit based primarily on years of service and compensation. Employees do not contribute to these pension plans.

In addition, we offer an unfunded, nonqualified supplemental pension plan. This plan restores the pension benefits from our regular pension plans that would have been payable to designated participants if it were not for limitations imposed by U.S. federal income tax regulations.

We also provide postretirement health care benefits and life insurance to eligible retired employees. NewMarket and retirees share in the cost of postretirement health care benefits. NewMarket pays the premium for the insurance contract that holds plan assets for retiree life insurance benefits.

The estimated net gain which will be amortized from accumulated other comprehensive loss into net periodic benefit cost during 2011 is expected to be $400 thousand for postretirement benefit plans. The estimated prior service cost which will be amortized from accumulated other comprehensive loss into net periodic benefit cost during 2011 is expected to be $300 thousand for pension plans and $9 thousand for postretirement benefit plans.

The 2010 plan amendment in the table above represents contract negotiations with the Sauget and Houston plans.

The accumulated benefit obligation for all domestic defined benefit pension plans was $130 million at December 31, 2010 and $120 million at December 31, 2009.

The projected benefit obligation exceeded the fair market value of plan assets for all domestic plans, except for the Port Arthur and Sauget plans, at December 31, 2010. The fair market value of the Port Arthur and Sauget assets exceeded the projected benefit obligation at December 31, 2010. The projected benefit obligation exceeded the fair market value of plan assets for all domestic plans at December 31, 2009. The fair market value of plan assets for all domestic plans, except the nonqualified plan, exceeded the accumulated benefit obligation at December 31, 2010. The accumulated benefit obligation exceeded the fair market value of plan assets for the nonqualified plan at December 31, 2010. The accumulated benefit obligation exceeded the fair market value of plan assets for all the domestic plans, except for the Port Arthur plan, at December 31, 2009. The fair market value of the Port Arthur plan assets exceeded the accumulated benefit obligation at December 31, 2009.

The net liability position of plans in which the projected benefit obligation exceeds assets is included in other noncurrent liabilities on the balance sheet. A portion of the accrued benefit cost for the nonqualified plan is included in current liabilities at both December 31, 2010 and December 31, 2009. As the nonqualified plan is unfunded, the amount reflected in current liabilities represents the expected benefit payments related to the nonqualified plan during 2011.

The following table shows information on domestic pension plans with the accumulated benefit obligation in excess of plan assets. The second table presents information on domestic pension plans with the projected benefit obligation in excess of plan assets.

There are no assets held in the nonqualified plan by the trustee for the retired beneficiaries of the nonqualified plan. Payments to retired beneficiaries of the nonqualified plan are made with cash from operations.

Assumptions—We used the following assumptions to calculate the results of our retirement plans:

	Pension Benefits									Postretirement Benefits
	2010			2009			2008			2010			2009			2008
Weighted-average assumptions used to determine net periodic benefit cost for years ended December 31
Discount rate		5.875	%		6.250	%		6.375	%		5.875	%		6.250	%		6.375	%
Expected long-term rate of return on plan assets		9.00	%		9.00	%		8.75	%		6.25	%		6.25	%		6.25	%
Rate of projected compensation increase		4.00	%		3.75	%		4.00	%
Weighted-average assumptions used to determine benefit obligations at December 31
Discount rate		5.875	%		5.875	%		6.250	%		5.875	%		5.875	%		6.250	%
Rate of projected compensation increase		3.50	%		4.00	%		3.75	%

We base the assumed expected long-term rate of return for plan assets on an analysis of our actual investments, including our asset allocation, as well as a stochastic analysis of expected returns. This analysis reflects the expected long-term rates of return for each significant asset class and economic indicator. As of January 1, 2011, the expected rates were 8.4% for U.S. large cap stocks, 3.6% for U.S. long-term corporate bonds, and 2.1% for inflation. The range of returns developed relies both on forecasts and on broad-market historical benchmarks for expected return, correlation, and volatility for each asset class. Our asset allocation is predominantly weighted toward equities. Through our ongoing monitoring of our investments, we have determined that we should maintain the expected long-term rate of return for our U.S. plans at 9.0% at December 31, 2010.

At December 31, 2010, we changed our method of developing the discount rate assumption. We utilize a proprietary model maintained by our actuarial consultant. The model determines the single effective discount rate for a unique hypothetical portfolio constructed from investment-grade bonds that, in aggregate, match the projected cash flows of each of our retirement plans. Our discount rate is developed based on the hypothetical portfolio on the last day of December.

Assumed health care cost trend rates at December 31 are shown in the table below. The expected health care cost trend rate for 2010 was 9.0% with temporarily higher cost increases for our retiree prescription drug coverage.

	2010			2009
Health care cost trend rate assumed for next year		8.5	%		9.0	%
Rate to which the cost trend rate is assumed to decline (the ultimate trend rate)		5.0	%		5.0	%
Year that the rate reaches the ultimate trend rate		2018			2018

A one-percentage point change in the assumed health care cost trend rate would have the following effects.

	1% Increase		1% Decrease
Effect on accumulated postretirement benefit obligation as of December 31, 2010	$	6,986	$	(5,587	)
Effect on net periodic postretirement benefit cost in 2010	$	756	$	(583	)

The Patient Protection and Affordable Care Act (PPACA), as amended by the Health Care and Education Reconciliation Act of 2010, was signed into law in March 2010. The PPACA mandates health care reforms with effective dates from 2010 to 2018, including an excise tax on high cost health care plans effective in 2018. The additional accumulated postretirement liability resulting from the PPACA is not material and has been included in the benefit obligation for our postretirement plan at December 31, 2010. Given the complexity of the PPACA and the extended time period during which implementation is currently expected to occur, additional adjustments to the benefit obligation may be necessary.

Plan Assets—Pension plan assets are held and distributed by trusts and consist principally of common stock and investment-grade fixed income securities. We invest directly in common stocks, as well as in funds which primarily hold stock and debt securities. Our target allocation is 90% to 97% in equities and 3% to 10% in debt securities or cash.

The pension obligation is long-term in nature and the investment philosophy followed by the Pension Investment Committee is likewise long-term in its approach. The majority of the pension funds are invested in equity securities as historically, equity securities have outperformed debt securities and cash investments resulting in a higher investment return over the long-term. While in the short-term, equity securities may underperform other investment classes, we are less concerned with short-term results and more concerned with long-term improvement. The pension funds are managed by six different investment companies who predominantly invest in U.S. large cap stocks. Each investment company’s performance is reviewed quarterly. A small portion of the funds is in investments, such as cash or short-term bonds, which historically has been less vulnerable to short-term market swings. These funds are used to provide the cash needed to meet our monthly obligations.

There are no significant concentrations of risk within plan assets, nor do the equity securities include any NewMarket common stock for any year presented.

The assets of the postretirement benefit plan are invested completely in an insurance contract held by Metropolitan Life. No NewMarket common stock is included in these assets.

The valuation methodologies used to develop the fair value measurements for the investments in the tables above are outlined below. There have been no changes in the valuation techniques used to value the investments.

• Equity securities, including common stock, real estate investment trusts, and exchange traded funds, are valued at the closing price reported on a national exchange.

• Securities which are part of the common collective trust are recorded at market value. Foreign securities are valued on the basis of quotations from the primary market in which they are traded and translated at each valuation date from the local currency into U.S. dollars using the mean between bid and asked market rates for such currencies. Securities traded on the over-the-counter markets for which reliable quotations are available are valued at the last current bid quotation. Securities traded on U.S. national exchanges are valued at the last reported sales price, or, if there are no sales, at the latest bid quotation. Spot and forward currency contracts are valued at the unrealized gain or loss on each contract, which is based on the difference between the contract rate and published spot rate for the contracted currencies. Short-term investments in other money market funds are valued at the underlying fund’s net asset value on the date of valuation.

Contributions to and withdrawals from the common collective trust may generally only be made effective on the first business day of a month.

• Mutual funds are valued at the closing price reported on a national exchange.

71

Notes to Consolidated Financial Statements—(Continued)

(tabular amounts in thousands, except per-share amounts)

• Money market instruments are valued at cost, which approximates fair value.

• Cash and cash equivalents are valued at cost.

• The insurance contracts are unallocated funds deposited with an insurance company and are stated at an amount equal to the sum of all amounts deposited less the sum of all amounts withdrawn, adjusted for investment return.

Cash Flows—For U.S. plans, NewMarket expects to contribute $23 million to the pension plans and $2 million to our other postretirement benefit plans in 2011. The expected benefit payments for the next ten years are as follows.

	Expected Pension Benefit Payments		Expected Postretirement Benefit Payments
2011	$	6,308	$	3,959
2012	$	6,695	$	3,878
2013	$	7,176	$	3,805

Foreign Retirement Plans

For most employees of our foreign subsidiaries, NewMarket has defined benefit pension plans that offer benefits based primarily on years of service and compensation. These defined benefit plans provide benefits for employees of our foreign subsidiaries located in Belgium, the United Kingdom, Germany, and Canada. NewMarket generally contributes to investment trusts and insurance policies to provide for these plans.

In addition to the foreign defined benefit pension plans, NewMarket also provides retirement benefits in Japan and Brazil which are not defined benefit plans. The total pension expense for these plans was $200 thousand for 2010, $100 thousand for 2009, and $300 thousand for 2008.

Our foreign subsidiary in Canada also sponsors a defined benefit postretirement plan. This postretirement plan provides certain health care benefits and life insurance to eligible retired employees. We pay the entire premium for these benefits.

The estimated net loss which will be amortized from accumulated other comprehensive loss into net periodic benefit cost during 2011 is expected to be $1 million for foreign pension plans and $60 thousand for foreign postretirement benefit plans. The estimated prior service cost which will be amortized from accumulated other comprehensive loss into net periodic benefit cost during 2011 is expected to be $80 thousand for foreign pension plans. There will be no estimated unrecognized transition asset amortized from accumulated other comprehensive loss into net periodic benefit cost during 2011 for foreign pension plans. The estimated unrecognized transition obligation which will be amortized from accumulated other comprehensive loss into net periodic benefit cost during 2011 is expected to be $50 thousand expense for foreign postretirement benefit plans.

The fair market value of plan assets exceeded both the accumulated benefit obligation and projected benefit obligation for the Canadian Salary plan and the United Kingdom plan at year-end 2010 and 2009. The net asset positions of the Canadian Salary plan and the United Kingdom plan are included in prepaid pension cost on the balance sheet in both 2010 and 2009. For the Canadian Hourly plan in 2010, the fair market value of plan assets

exceeded the accumulated benefit obligation, but not the projected benefit obligation. The net liability position of the Canadian Hourly plan is included in noncurrent liabilities.

The accumulated benefit obligation and projected benefit obligation exceeded the fair market value of plan assets for the German and Afton Belgium plans at December 31, 2010 and for the German, Afton Belgium, and Canadian hourly plans at December 31, 2009. The accrued benefit cost of these plans is included in other noncurrent liabilities on the balance sheet. As the German plan is unfunded, a portion of the accrued benefit cost for the German plan is included in current liabilities at year-end 2010 and year-end 2009 reflecting the expected benefit payments related to the plan for the following year.

The Ethyl Belgium plan was terminated and all liabilities settled in 2009.

Rate of projected compensation increase		4.63	%		4.22	%		4.24	%

The actual assumptions used by the various foreign locations are based upon the circumstances of each particular country and pension plan. The factors impacting the determination of the long-term rate of return for a particular foreign pension plan include the market conditions within a particular country, as well as the investment strategy and asset allocation of the specific plan.

Effect on accumulated postretirement benefit obligation as of December 31, 2010	$	333	$	(395	)
Effect on net periodic postretirement benefit cost in 2010	$	28	$	(25	)

Plan Assets—Pension plan assets vary by foreign location and plan. Assets are held and distributed by trusts and, depending upon the foreign location and plan, consist primarily of equity securities, corporate and government debt securities, cash, and insurance contracts. The combined average target allocation of our foreign pension plans is 53% in equities, 34% in debt securities, 9% in insurance contracts, and 4% in a pooled investment property fund.

While the pension obligation is long-term in nature for each of our foreign plans, the investment strategies followed by each plan vary to some degree based upon the laws of a particular country, as well as the provisions of the specific pension trust. The United Kingdom and Canadian plans are invested predominantly in equity securities and debt securities. The funds of these plans are managed by various trustees and investment companies whose performance is reviewed throughout the year. The Afton Belgium plan is invested in an insurance contract. The German plan has no assets.

There are no significant concentrations of risk within plan assets, nor do the equity securities include any NewMarket common stock for any year presented. The benefits of the Canadian postretirement benefit plan are paid through an insurance contract.

The valuation methodologies used to develop the fair value measurements for the investments in the table above are outlined below. There have been no changes in the valuation techniques used to value the investments.

• Equity securities are valued at the closing price reported on a national exchange.

• Corporate and government debt securities are composed of bond funds that are priced daily.

• Cash and cash equivalents are valued at cost.

• The insurance contracts are funds deposited with an insurance company and are stated at an amount equal to the sum of all amounts deposited less the sum of all amounts withdrawn, adjusted for investment return.

• The pooled investment funds are priced daily. The underlying assets that are invested in equity securities, as well as corporate and government debt securities are listed on a recognized exchange. The underlying assets that are invested in property are valued monthly by an independent property management firm.

Cash Flows—For foreign pension plans, NewMarket expects to contribute $6 million to the plans in 2011. We expect to contribute approximately $200 thousand to the Canadian postretirement benefit plan. The expected benefit payments for the next ten years are as follows:

	Expected Pension Benefit Payments		Expected Postretirement Benefit Payments
2011	$	3,843	$	163

20. Other (Expense) Income, Net

Other expense, net was $10 million in 2010 and $11 million in 2009, primarily representing a loss on an interest rate swap derivative instrument recorded at fair value, which we entered into on June 25, 2009. See Note 16 for additional information on the interest rate swap. Other income, net was $1 million in 2008 resulting primarily from investment income.

21. Gains and Losses on Foreign Currency

Transactions conducted in a foreign currency resulted in a net loss of $2 million in 2010, a net loss of $8 million in 2009, and a net gain of $3 million in 2008. These amounts are reported in cost of sales.

The reconciliation of the U.S. federal statutory rate to the effective income tax rate follows:

	% of Income       Before Income Tax Expense
	2010			2009			2008
Federal statutory rate		35.0	%		35.0	%		35.0	%
State taxes, net of federal tax		1.4			1.8			1.6

Other items and adjustments		(0.5	)		(0.5	)		(1.1	)
Effective income tax rate		31.9	%		32.2	%		30.5	%

For those foreign subsidiaries that we have not determined their undistributed earnings to be indefinitely reinvested and based on available foreign tax credits and current U.S. income tax rates, we believe that we have adequately provided for any additional U.S. taxes that would be incurred when one of these foreign subsidiaries returns its earnings in cash to Afton or Ethyl.

Certain foreign operations have a U.S. tax impact due to our election to include their earnings in our federal income tax return.

Our deferred income tax assets and liabilities follow.

Our deferred taxes are in a net asset position at December 31, 2010. Based on current forecast operating plans and historical profitability, we believe that we will recover nearly the full benefit of our deferred tax assets and have, therefore, recorded an immaterial valuation allowance at a foreign subsidiary.

A reconciliation of the beginning and ending balances of the unrecognized tax benefits from uncertain positions is as follows:

Balance at January 1, 2008	$	2,583
Additions for tax positions of prior years		1,474
Reductions as a result of settlements with tax authorities		(182	)
Decreases for tax positions of prior years		(1,484	)
Balance at December 31, 2008		2,391
Additions for tax positions of prior years		200
Reductions as a result of settlements with tax authorities		(1,474	)
Decreases for tax positions of prior years		(200	)
Balance at December 31, 2009		917
Additions for tax positions of prior years		333
Reductions as a result of settlements with tax authorities		(200	)
Decreases for tax positions of prior years		(317	)
Balance at December 31, 2010	$	733

All of the balance at December 31, 2010, if recognized, would affect our effective tax rate.

During the year ended December 31, 2010, we reduced the accrued interest associated with uncertain tax positions by an immaterial amount resulting in a net accrued interest of approximately $50 thousand. During the year ended December 31, 2009, we reduced the accrued interest associated with uncertain tax positions by approximately $250 thousand resulting in a net accrued interest of approximately $50 thousand. During the year ended December 31, 2008, we reduced the accrued interest associated with uncertain tax positions by $400 thousand, resulting in net accrued interest of $300 thousand. We recognize accrued interest and penalties associated with uncertain tax positions as part of income tax expense on our consolidated statements of income.

We expect the amount of unrecognized tax benefits to change in the next twelve months; however, we do not expect the change to have a material impact on our financial statements.

Our U.S. subsidiaries join in the filing of a U.S. federal consolidated income tax return. The Internal Revenue Service (IRS) completed its examination of our consolidated federal income tax returns for the years 2005 and 2006 during 2008. Foreign and U.S. state jurisdictions have statutes of limitations generally ranging from three to five years. Years still open to examination by foreign tax authorities in major jurisdictions include: the United Kingdom (2007 and forward); Singapore (2008 and forward); Japan (2008 and forward); Belgium (2007 and forward); and Canada (2003 and forward). We are currently under examination in various U.S. state and foreign jurisdictions.

24. Segment and Geographic Area Information

Segment Information—The tables below show our consolidated segment results. The “All other” category includes the continuing operations of the TEL business, as well as certain contract manufacturing Ethyl provides to Afton and to third parties.

The accounting policies of the segments are the same as those described in Note 1. We evaluate the performance of the petroleum additives business based on operating profit. NewMarket Services departments and other expenses are billed to Afton and Ethyl based on the services provided under the holding company structure. Depreciation on segment property, plant, and equipment, as well as amortization of segment intangible assets is included in segment operating profit. No transfers occurred between the petroleum additives segment, the real estate development segment or the “All other” category during the periods presented. The table below reports revenue and operating profit by segment, as well as a reconciliation to income before income taxes for the last three years.

(a) Net sales to one customer of our petroleum additives segment exceeded 10% of consolidated revenue in 2010, 2009, and 2008. Sales to Royal Dutch Shell plc and its affiliates (Shell) amounted to $217 million (12% of consolidated revenue) in 2010, $232 million (15% of consolidated revenue) in 2009, and $261 million (16% of consolidated revenue) in 2008. These sales represent a wide-range of products sold to this customer in multiple regions of the world.

(b) Operating profit for the petroleum additives segment in 2008 includes a gain of $3 million from a class action lawsuit related to raw materials.

26. Consolidating Financial Information

The 7.125% senior notes due 2016 are fully and unconditionally guaranteed by certain of our subsidiaries (Guarantor Subsidiaries) on a joint and several unsecured senior basis. The Guarantor Subsidiaries include all of our existing and future 100% owned domestic restricted subsidiaries. The Guarantor Subsidiaries and the subsidiaries that do not guarantee the senior notes (the Non-Guarantor Subsidiaries) are 100% owned by NewMarket Corporation (the Parent Company). The Guarantor Subsidiaries consist of the following:

Ethyl Corporation	Afton Chemical Corporation
Ethyl Asia Pacific LLC	Afton Chemical Asia Pacific LLC
Ethyl Canada Holdings, Inc.	Afton Chemical Canada Holdings, Inc.
Ethyl Export Corporation	Afton Chemical Japan Holdings, Inc.
Ethyl Interamerica Corporation	Afton Chemical Additives Corporation
Ethyl Ventures, Inc.	NewMarket Services Corporation
Interamerica Terminals Corporation	The Edwin Cooper Corporation
Afton Chemical Intangibles LLC	Old Town LLC
NewMarket Investment Company	NewMarket Development Corporation
Foundry Park I, LLC	Foundry Park II, LLC
Gamble’s Hill, LLC	Gamble’s Hill Lab, LLC
Gamble’s Hill Landing, LLC	Gamble’s Hill Third Street, LLC
Gamble’s Hill Tredegar, LLC	Polartech Additives, Inc.

We conduct all of our business and derive essentially all of our income from our subsidiaries. Therefore, our ability to make payments on the senior notes or other obligations is dependent on the earnings and the distribution of funds from our subsidiaries. There are no restrictions on the ability of any of our domestic subsidiaries to transfer funds to the Parent Company.

The following sets forth the Consolidating Statements of Income for the years ended December 31, 2010, December 31, 2009, and December 31, 2008; Consolidating Balance Sheets as of December 31, 2010 and December 31, 2009; and Condensed Consolidating Statements of Cash Flows for the years ended December 31, 2010, December 31, 2009, and December 31, 2008 for the Parent Company, the Guarantor Subsidiaries and Non-Guarantor Subsidiaries. The financial information is based on our understanding of the SEC’s interpretation and application of Rule 3-10 of the SEC Regulation S-X.

The financial information may not necessarily be indicative of results of operations or financial position had the Guarantor Subsidiaries or Non-Guarantor Subsidiaries operated as independent entities. The Parent Company accounts for investments in these subsidiaries using the equity method.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

None.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We maintain a system of internal control over financial reporting to provide reasonable, but not absolute, assurance of the reliability of the financial records and the protection of assets. Our controls and procedures include written policies and procedures, careful selection and training of qualified personnel, and an internal audit program. We use a third-party firm, separate from our independent registered public accounting firm, to assist with internal audit services.

We work closely with the business groups, operations personnel, and information technology to ensure transactions are recorded properly. Environmental and legal staff are consulted to determine the appropriateness of our environmental and legal liabilities for each reporting period. We regularly review the regulations and rule changes that affect our financial disclosures.

Our disclosure control procedures include signed representation letters from our regional officers, as well as senior management.

We have a Financial Disclosure Committee, which is made up of the president of Afton, the general counsel of NewMarket, and the controller of NewMarket. The committee, as well as regional management, makes representations with regard to the financial statements that, to the best of their knowledge, the report does not contain any misstatement of a material fact or omit a material fact that is necessary to make the statements not misleading with respect to the periods covered by the report.

The committee and the regional management also represent, to the best of their knowledge, that the financial statements and other financial information included in the report fairly present, in all material respects, the financial condition, results of operations and cash flows of the company as of and for the periods presented in the report.

Pursuant to Rule 13a-15(b) under the Securities Exchange Act of 1934 (the Exchange Act), we carried out an evaluation, with the participation of our management, including our principal executive officer and our principal financial officer, of the effectiveness of our disclosure controls and procedures (as defined under Rule 13a-15(e)) under the Exchange Act as of the end of the period covered by this report. Based upon that evaluation, our principal executive officer and our principal financial officer concluded that our disclosure controls and procedures are effective.

There has been no change in our internal control over financial reporting, as such term is defined in Rule 13a-15(f) under the Exchange Act, during the quarter ended December 31, 2010 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

95

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 Rule 13a-15(f), under the Securities Exchange Act of 1934.

Our 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 accounting principles generally accepted in the United States of America. Internal control over financial reporting includes those policies and procedures that:

• pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of our assets;

• provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with accounting principles generally accepted in the United States of America and that our receipts and expenditures are being made only in accordance with authorization of our management and directors; and

• provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of assets that could have a material effect on the consolidated 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.

Under the supervision and with the participation of our management, including our principal executive officer and principal 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 concluded that our internal control over financial reporting was effective at the reasonable assurance level as of December 31, 2010. The effectiveness of our internal control over financial reporting as of December 31, 2010, has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report, which is included in Item 8 of this Annual Report on Form 10-K.
