PART I

Item 1. Business

Overview—Mine Safety Appliances Company was incorporated in Pennsylvania in 1914. We are a global leader in the development, manufacture and supply of products that protect people’s health and safety. Our safety products typically integrate any combination of electronics, mechanical systems, and advanced materials to protect users against hazardous or life threatening situations. Our comprehensive line of safety products is used by workers around the world in the fire service, homeland security, oil and gas, construction, and other industries, as well as the military. Our broad product offering includes self-contained breathing apparatus, or SCBAs, gas masks, gas detection instruments, head protection, respirators, thermal imaging cameras, fall protection, and ballistic helmets and body armor. We also provide a broad offering of consumer and contractor safety products through retail channels.

We dedicate significant resources to research and development, which allows us to produce innovative safety products that are often first to market and exceed industry standards. Our global product development teams include cross-geographic and cross-functional members from various functional areas throughout the company, including research and development, marketing, sales, operations, and quality management. Our engineers and technical associates work closely with the safety industry’s leading standards-setting groups and trade associations, such as the National Institute for Occupational Safety and Health, or NIOSH, and the National Fire Protection Association, or NFPA, to develop industry product requirements and standards and to anticipate their impact on our product lines.

Segments—We tailor our product offerings and distribution strategy to satisfy distinct customer preferences that vary across geographic regions. We believe that we best serve these customer preferences by organizing our business into three reportable geographic segments: North America, Europe, and International. Segment information is presented in the note entitled “Segment Information” in Item 8—Financial Statements and Supplementary Data.

Because our financial statements are stated in U.S. dollars, currency fluctuations may affect our results of operations and financial position and may affect the comparability of our results between financial periods.

Principal Products—We manufacture and sell a comprehensive line of safety products to protect workers around the world in the fire service, homeland security, oil and gas, construction, and other industries, as well as the military. We also provide a broad offering of consumer and contractor safety products through retail channels. Our products protect people against a wide variety of hazardous or life-threatening situations. The following is a brief description of each of our principal product categories:

Respiratory protection. Respiratory protection products are used to protect against the harmful effects of contamination caused by dust, gases, fumes, volatile chemicals, sprays, micro-organisms, fibers, and other contaminants. We offer a broad and comprehensive line of respiratory protection products.

•

Self Contained Breathing Apparatus. SCBAs are used by first responders, petrochemical plant workers, and anyone entering an environment deemed immediately dangerous to life and health. SCBAs are also used by first responders to protect against exposure to chemical, biological, radiological, and nuclear, or CBRN, agents. Our FireHawk^®M7 SCBA meets the latest performance requirements adopted by the NFPA. The FireHawk^®M7 Air Mask was the first device of its kind to be certified by the Safety Equipment Institute, or SEI, as NFPA compliant for both its breathing apparatus and Personal Alert Safety System, or PASS. The PASS device is an SCBA component that sounds a loud, piercing alarm when a firefighter becomes disabled or lies motionless for 30 seconds.

•

Air-purifying respirators. Air-purifying respirators range from the simple, filtering types to powered full-facepiece versions for many hazardous applications, including:

•

full-face gas masks for military personnel and first responders exposed to known and unknown concentrations of hazardous gases, chemicals, vapors, and particulates;

•

half-mask respirators for industrial workers, painters, and construction workers exposed to known concentrations of gases, vapors, and particulates;

•

powered-air purifying respirators for industrial, hazmat, and remediation workers who have longer term exposures to hazards in their work environment; and

•

dust and pollen masks for maintenance workers, contractors, and at-home consumers exposed to nuisance dusts, allergens, and other particulates.

•

Gas masks. We have supplied gas masks to the U.S. military for several decades. The latest versions of these masks are currently in use by the U.S. military in Iraq, Afghanistan, and other parts of the world. Our commercial version of this gas mask, the Millennium, was developed based on the MCU-2/P, the gas mask currently used by the U.S. Air Force and U.S. Navy.

•

Escape hoods. Our Response Escape Hood is used by law enforcement personnel, government workers, chemical and pharmaceutical workers, and anyone needing to escape from unknown concentrations of a chemical, biological or radiological release of toxic gases and vapors. The hood gives users head and upper neck coverage and respiratory protection to help them escape from threatening situations quickly and easily.

Portable and permanent gas detection instruments. Our portable and permanent instruments are used to detect the presence or absence of various gases in the air. These instruments can be either hand-held or permanently installed. Typical applications of these instruments include the detection of the lack of oxygen in confined spaces or the presence of combustible or toxic gases.

•

Single- and multi-gas hand-held detectors. Our single- and multi-gas detectors provide portable solutions for detecting the presence of oxygen, combustible gases and various toxic gases, including hydrogen sulfide, carbon monoxide, ammonia and chlorine, either singularly or up to six gases at once. Our hand-held portable instruments are used by chemical workers, oil and gas workers, utility workers entering confined spaces, or anywhere a user needs to continuously monitor the quality of the atmosphere they are working in and around. Our ALTAIR $X multi-gas detector with xcell sensor technology provides faster response times and unsurpassed durability in a tough, easy to operate package.

•

Multi-point permanently installed gas detection systems. Our comprehensive line of gas detection systems is used to continuously monitor for combustible and toxic gases and oxygen deficiency in virtually any application where continuous monitoring is required. Our systems are used for gas detection in pulp and paper, refrigerant monitoring, petrochemical, and general industrial applications. One of our newest lines, the SafeSite^® Multi-Threat Wireless Detection System, designed and developed for homeland security applications, combines the technologies and features from our line of permanent and portable gas detection offerings. The SafeSite System detects and communicates the presence of toxic industrial chemicals and chemical warfare agents. With up to 16 monitoring stations, wirelessly connected to a base station, the SafeSite System allows law enforcement officials to rapidly deploy and set up perimeter gas sensing sentinels that continuously monitor the air for toxic gases at large public events, in subways or at federal facilities, and continuously report their status to incident command.

•

Flame detectors and open-path infrared gas detectors. Our flame and combustible gas detectors are used for plant-wide monitoring of toxic gases and for detecting the presence of flames. These systems use infrared optics to detect potentially hazardous conditions across distances as far as 120 meters, making them suitable for use in such places as offshore oil rigs, storage vessels, refineries, pipelines, and ventilation ducts. First used in the oil and gas industry, our systems currently have broad applications in petrochemical facilities, the transportation industry, and in pharmaceutical production.

Thermal imaging cameras. Our hand-held infrared thermal imaging cameras, or TICs, are used in the global fire service market. TICs detect sources of heat in order to locate downed firefighters and other people trapped inside burning or smoke-filled structures. TICs can also be used to identify “hot spots.” Our Evolution^® 5000 series TICs are unmatched for ease of use and durability. Our Evolution^® 5800 TIC, the newest addition to our

5000 series of TICs, offers state-of-the-art imagery in a high resolution format. Our Evolution 5600 Thermal Imaging Camera provides high resolution and an extended high sensitivity operating range in a rugged, user-friendly and affordable design.

Head, eye, face, and hearing protection. Head, eye, face, and hearing protection is used in work environments where hazards present dangers such as dust, flying particles, metal fragments, chemicals, extreme glare, optical radiation, and items dropped from above.

•

Industrial hard hats. Our broad line of hard hats include full-brim hats and traditional hard hats, available in custom colors and with custom logos. These hard hats are used by plant, steel and construction workers, miners and welders.

•

Fire helmets. Our fire service products include leather, traditional, modern, and specialty helmets designed to satisfy the preferences of firefighters across geographic regions. Our CairnsHELMET is the number one helmet in the North American fire service market based on 2010 sales. Similarly, our Gallet firefighting helmet has a number one market position in Europe based on 2010 sales.

•

Military helmets and communication systems. The Advanced Combat Helmet, or ACH, is used by the military for ballistic head protection. The ACH was originally designed for the Special Forces of the U.S. military and has now been designated as the “basis of issue” by the U.S. Army. In recent years, military forces in Iraq and Afghanistan have trusted MSA’s battle-tested ACH and related Modular Integrated Communication Headset, or MICH™. MICH is a light weight and comfortable communication system that provides superior hearing protection as well as clear radio/intercom communications.

•

Eye, face, and hearing protection. Our broad line of hearing protection products, non-prescription protective eyewear, and face shields is used by workers in a wide variety of industries.

Body protection.

•

Fall protection. Our broad line of fall protection equipment includes confined space equipment, harnesses/fall arrest equipment, lanyards, and lifelines.

•

Ballistic body armor. Our MSA Paraclete Releasable Assault Vest and Releasable Modular Vest are used primarily by the U.S. military, including Special Forces Units. Our ForceField™ Body Armor line features concealable ballistic vests and over-the-uniform tactical vests designed primarily for law enforcement applications.

Customers—Our customers generally fall into three categories: industrial and military end-users, distributors, and retail consumers. In North America, we make nearly all of our non-military sales through our distributors. In our European and International segments, we make our sales through both indirect and direct sales channels. Our U.S. military customers, which are comprised of multiple U.S. government entities, including the Department of Defense, accounted for approximately 4% of our 2010 sales. The year-end backlog of orders under contracts with U.S. government agencies was $56.0 million in 2010, $18.3 million in 2009, and $23.4 million in 2008.

Industrial and military end-users—Examples of the primary industrial and military end-users of our core products are listed below:


Products		Primary End-Users
Respiratory Protection		First Responders; General Industry Workers; Military Personnel

Gas Detection		Oil, Gas, Petrochemical and Chemical Workers; First Responders; Hazmat, and Confined Space Workers

Head, Eye and Face, and Hearing Protection		Construction Workers and Contractors; First Responders; General Industry Workers; Military Personnel

Thermal Imaging Cameras		First Responders

Sales and Distribution—Our sales and distribution team consists of distinct marketing, field sales and customer service organizations for our three geographic segments: North America, Europe, and International. We believe our sales and distribution team, totaling over 400 dedicated associates, is the largest in our industry. In most geographic areas, our field sales organizations work jointly with select distributors to call on end-users, educating them about hazards, exposure limits, safety requirements, and product applications, as well as specific performance requirements of our products. In our International segment and Eastern Europe where distributors are not as well established, our sales associates often work with and sell directly to end-users. We believe that the development of relationships with end-users is critical to increasing the overall demand for our products.

The in-depth customer training and education provided by our sales associates to our customers are critical to ensure proper use of many of our products, such as SCBAs and gas detection instruments. As a result of our sales associates working closely with end-users, they gain valuable insight into customer preferences and needs. To better serve our customers and to ensure that our sales associates are among the most knowledgeable and professional in the industry, we place significant emphasis on training our sales associates with respect to product application, industry standards and regulations, sales skills and sales force automation.

We believe our sales and distribution strategy allows us to deliver a customer value proposition that differentiates our products and services from those of our competitors, resulting in increased customer loyalty and demand.

In areas where we use indirect selling, we promote, distribute, and service our products to general industry through select authorized national, regional, and local distributors. Some of our key distributors include Airgas, W.W. Grainger Inc., Fastenal, and Hagemeyer. In North America, we distribute fire service products primarily through specially trained local and regional distributors who provide advanced training and service capabilities to volunteer and paid municipal fire departments. In our European and International segments, we primarily sell to and service the fire service market directly. Because of our broad and diverse product line and our desire to reach as many markets and market segments as possible, we have over 4,000 authorized distributor locations worldwide.

We market consumer products under the MSA Safety Works brand through a dedicated sales and marketing force. We serve the retail consumer through various channels, including distributors, such as Orgill, hardware and equipment rental outlets, such as United Rentals, and retail chains, such as The Home Depot, TrueValue and Do-it Best.

Competition—We believe the worldwide personal protection equipment market, including the sophisticated safety products market in which we compete, generates annual sales in excess of $19 billion. The industry supplying this market is broad and highly fragmented with few participants offering a comprehensive line of safety products. Over the long-term, we believe global demand for safety products will be stable or growing because purchases of these products are non-discretionary since they protect workers in hazardous and life-threatening work environments and because their use is often mandated by government and industry regulations. Moreover, safety products industry revenues reflect the need to consistently replace many safety products that have limited life spans due to normal wear-and-tear or because they are one-time use products by design.

The safety products market is highly competitive, with participants ranging in size from small companies focusing on a single type of personal protection equipment to a few large multinational corporations that manufacture and supply many types of sophisticated safety products. Our main competitors vary by region and product. We believe that participants in this industry compete primarily on the basis of product characteristics (such as functional performance, agency approvals, design and style), price, brand name recognition and service.

We believe we compete favorably within each of our operating segments as a result of our high quality and cost-efficient product offerings and strong brand trust and recognition.

Research and Development—To maintain our position at the forefront of safety equipment technology, we operate several sophisticated research and development facilities. We believe our dedication and commitment to innovation and research and development allow us to produce innovative safety products that are often first to market and exceed industry standards. In 2010, 2009, and 2008, on a global basis, we spent $32.8 million, $28.8 million, and $35.0 million, respectively, on research and development. Our primary engineering groups are located in the United States, Germany, and China, and to a lesser extent in France. Our global product development teams include cross-geographic and cross-functional members from various areas throughout the company, including research and development, marketing, sales, operations, and quality management. These teams are responsible for setting product line strategy based on their understanding of the markets and the technologies, opportunities and challenges they foresee in each product area. We believe our team-based, cross-geographic and cross-functional approach to new product development is a source of competitive advantage. Our approach to the new product development process allows us to tailor our product offerings and product line strategies to satisfy distinct customer preferences and industry regulations that vary across our three geographic segments.

We believe another important aspect of our approach to new product development is that our engineers and technical associates work closely with the safety industry’s leading standards-setting groups and trade associations, such as the National Institute for Occupational Safety and Health, or NIOSH, and the National Fire Protection Association, or NFPA, to develop industry product requirements and standards and anticipate their impact on our product lines. For example, nearly every consensus standard-setting body around the world that impacts our product lines has one of our key managers as a voting member. Key members of our management team understand the impact that these standard-setting organizations have on our new product development pipeline and devote time and attention to anticipating a new standard’s impact on our sales and operating results. Because of our technological sophistication, commitment to and membership on global standard-setting bodies, resource dedication to research and development and unique approach to the new product development process, we believe we are well-positioned to anticipate and adapt to the needs of changing product standards and gain the approvals and certifications necessary to meet new government and multinational product regulations.

Patents and Intellectual Property—We own and have obtained licenses to significant intellectual property, including a number of domestic and foreign patents, patent applications and trademarks related to our products, processes and business. Although our intellectual property plays an important role in maintaining our competitive position in a number of markets that we serve, no single patent, or patent application, trademark or license is, in our opinion, of such value to us that our business would be materially affected by the expiration or termination thereof, other than the “MSA” trademark. Our patents expire at various times in the future not exceeding 20 years. Our general policy is to apply for patents on an ongoing basis in the United States and other countries, as appropriate, to perfect our patent development. In addition to our patents, we have also developed or acquired a substantial body of manufacturing know-how that we believe provides a significant competitive advantage over our competitors.

Raw Materials and Suppliers—Many of the components of our products are formulated, machined, tooled, or molded in-house from raw materials. For example, we rely on integrated manufacturing capabilities for breathing apparatus, gas masks, ballistic helmets, hard hats, and circuit boards. The primary raw materials that we source from third parties include rubber, chemical filter media, eye and face protective lenses, air cylinders, certain metals, electronic components, and ballistic resistant and non-ballistic fabrics. We purchase these materials both domestically and internationally, and we believe our supply sources are both well established and reliable. We have close vendor relationship programs with the majority of our key raw material suppliers. Although we generally do not have long-term supply contracts, we have not experienced any significant problems in obtaining adequate raw materials.

Associates—At December 31, 2010, we had approximately 5,200 associates, approximately 3,100 of whom were employed by our European and International segments. None of our U.S. associates are subject to the provisions of a collective bargaining agreement. Some of our associates outside the United States are members of unions. We have not experienced a work stoppage in over 10 years and believe our relations with our associates are good.

Item 1A. Risk Factors

The speed and duration of the economic recovery could materially and adversely affect our business, results of operations, and financial condition.

The recent global recession, distress in the financial markets and general uncertainty about the economy had a significant negative impact on governments, businesses and consumers around the world. The effects of the recession and the ongoing recovery may impact the operations or liquidity of any party with whom we conduct business and could adversely affect our business. If the speed and duration of the recovery is protracted, we could experience declines in revenue, profitability and cash flow due to reduced orders, payment delays, supply chain disruptions or other factors caused by the economic challenges faced by our customers and suppliers. We are unsure of the continuing duration of the recession and the length of the recovery. However, a slow and protracted recovery could have a material adverse effect on our business, results of operations and financial condition.

A reduction in the spending patterns of government agencies could materially and adversely affect our net sales, earnings and cash flow.

The demand for our products sold to the fire service market, the homeland security market, and to U.S. government agencies, including the Department of Defense, is, in large part, driven by available government funding. For example, the level of government funding in these markets increased significantly after the attacks of September 11, 2001, fueling the demand for many of our products such as SCBAs, gas masks, and Advanced Combat Helmets, and declined in 2005 and 2006, as government funding priorities changed. Approximately 4% of our net sales for the year ended December 31, 2010 were made directly to U.S. military customers. Government budgets are set annually and we cannot assure you that government funding will be sustained at the same level in the future. A significant reduction in available government funding could materially and adversely affect our net sales, earnings and cash flow.

The markets in which we compete are highly competitive, and some of our competitors have greater financial and other resources than we do. The competitive pressures faced by us could materially and adversely affect our business, results of operations and financial condition.

The safety products market is highly competitive, with participants ranging in size from small companies focusing on single types of safety products, to large multinational corporations that manufacture and supply many types of safety products. Our main competitors vary by region and product. We believe that participants in this industry compete primarily on the basis of product characteristics (such as functional performance, agency approvals, design and style), price, brand name trust and recognition, and customer service. Some of our competitors have greater financial and other resources than we do and our business could be adversely affected by competitors’ new product innovations, technological advances made to competing products and pricing changes made by us in response to competition from existing or new competitors. We may not be able to compete successfully against current and future competitors and the competitive pressures faced by us could materially and adversely affect our business, results of operations and financial condition.

If we fail to introduce successful new products or extend our existing product lines, we may lose our market position and our financial performance may be materially and adversely affected.

In the safety products market, there are frequent introductions of new products and product line extensions. If we are unable to identify emerging consumer and technological trends, maintain and improve the competitiveness of our products and introduce new products, we may lose our market position, which could have a materially adverse effect on our business, financial condition and results of operations. Although we continue to invest significant resources in research and development and market research, continued product development and marketing efforts are subject to the risks inherent in the development of new products and product line extensions, including development delays, the failure of new products and product line extensions to achieve anticipated levels of market acceptance, and the cost of failed product introductions.

Product liability claims and our inability to collect related insurance receivables could have a materially adverse effect on our business, operating results, and financial condition.

We face an inherent business risk of exposure to product liability claims arising from the alleged failure of our products to prevent the types of personal injury or death against which they are designed to protect. Although we have not experienced any material uninsured losses due to product liability claims, it is possible that we could experience material losses in the future. In the event any of our products prove to be defective, we could be required to recall or redesign such products. In addition, we may voluntarily recall or redesign certain products that could potentially be harmful to end users. A successful claim brought against us in excess of available insurance coverage, or any claim or product recall that results in significant expense or adverse publicity against us, could have a materially adverse effect on our business, operating results, and financial condition.

In the normal course of business, we make payments to settle product liability claims and for related legal fees and record receivables for the amounts covered by insurance. Various factors could affect the timing and amount of recovery of insurance receivables, including: the outcome of negotiations with insurers, legal proceedings with respect to product liability insurance coverage, and the extent to which insurers may become insolvent in the future. Failure to recover amounts due from our insurance carriers could have a materially adverse effect on our business, operating results, and financial condition.

Our ability to market and sell our products is subject to existing regulations and standards. Changes in such regulations and standards or our failure to comply with them could materially and adversely affect our results of operations.

Most of our products are required to meet performance and test standards designed to protect the health and safety of people around the world. Our inability to comply with these standards may materially and adversely affect our results of operations. Changes in regulations could reduce the demand for our products or require us to reengineer our products, thereby creating opportunities for our competitors. Regulatory approvals for our products may be delayed or denied for a variety of reasons that are outside of our control. Additionally, market anticipation of significant new standards, such as the National Fire Protection Association (NFPA) standard for breathing apparatus which became effective August 31, 2007, can cause customers to accelerate or delay buying decisions.

We have significant international operations, and we are subject to the risks of doing business in foreign countries.

We have business operations in over 30 foreign countries. In 2010, approximately 57% of our net sales were made by operations located outside the United States. Our international operations are subject to various political, economic, and other risks and uncertainties, which could adversely affect our business. These risks include the following:

•

currency exchange rate fluctuations;

•

unexpected changes in regulatory requirements;

•

changes in trade policy or tariff regulations;

•

changes in tax laws and regulations;

•

intellectual property protection difficulties;

•

difficulty in collecting accounts receivable;

•

complications in complying with a variety of foreign laws and regulations, some of which may conflict with U.S. laws;

•

trade protection measures and price controls;

•

trade sanctions and embargos;

•

nationalization and expropriation;

•

increased international instability or potential instability of foreign governments;

•

the need to take extra security precautions for our international operations; and

•

costs and difficulties in managing culturally and geographically diverse international operations.

Any one or more of these risks could have a negative impact on the success of our international operations, and thereby materially and adversely affect our business as a whole.

Our future results are subject to availability of, and fluctuations in the costs of, purchased components and materials due to market demand, currency exchange risks, material shortages, and other factors.

We depend on various components and materials to manufacture our products. Although we have not experienced any difficulty in obtaining components and materials, it is possible that any of our supplier relationships could be terminated. Any sustained interruption in our receipt of adequate supplies could have a materially adverse effect on our business, results of operations and financial condition. We cannot assure you that we will be able to successfully manage price fluctuations due to market demand, currency risks or material shortages, or that future price fluctuations will not have a materially adverse effect on our business, results of operations and financial condition.

If we lose any of our key personnel or are unable to attract, train and retain qualified personnel, our ability to manage our business and continue our growth would be negatively impacted.

Our success depends in large part on the continued contributions of our key management, engineering, and sales and marketing personnel, many of whom are highly skilled and would be difficult to replace. Our success also depends on the abilities of new personnel to function effectively, both individually and as a group. If we are unable to attract, effectively integrate and retain management, engineering or sales and marketing personnel, then the execution of our growth strategy and our ability to react to changing market requirements may be impeded, and our business could suffer as a result. Competition for personnel is intense, and we cannot assure you that we will be successful in attracting and retaining qualified personnel. In addition, we do not currently maintain key person life insurance.

We are subject to various environmental laws and any violation of these laws could adversely affect our results of operations.

We are subject to federal, state, and local laws, regulations and ordinances relating to the protection of the environment, including those governing discharges to air and water, handling and disposal practices for solid and hazardous wastes, and the maintenance of a safe workplace. These laws impose penalties for noncompliance and liability for response costs and certain damages resulting from past and current spills, disposals, or other releases

of hazardous materials. We could incur substantial costs as a result of noncompliance with or liability for cleanup pursuant to these environmental laws. Environmental laws have changed rapidly in recent years, and we may be subject to more stringent environmental laws in the future. If more stringent environmental laws are enacted, these future laws could have a materially adverse effect on our results of operations.

Our inability to successfully identify, consummate and integrate future acquisitions, or to realize anticipated cost savings and other benefits could adversely affect our business.

One of our operating strategies is to selectively pursue acquisitions. Any future acquisitions will depend on our ability to identify suitable acquisition candidates and successfully consummate such acquisitions. Acquisitions involve a number of risks including:

•

failure of the acquired businesses to achieve the results we expect;

•

diversion of our management’s attention from operational matters;

•

our inability to retain key personnel of the acquired businesses;

•

risks associated with unanticipated events or liabilities;

•

potential disruption of our existing business; and

•

customer dissatisfaction or performance problems at the acquired businesses.

If we are unable to integrate or successfully manage businesses that we have recently acquired or may acquire in the future, we may not realize anticipated cost savings, improved manufacturing efficiencies and increased revenue, which may result in materially adverse short- and long-term effects on our operating results, financial condition and liquidity. Even if we are able to integrate the operations of our acquired businesses into our operations, we may not realize the full benefits of the cost savings, revenue enhancements or other benefits that we may have expected at the time of acquisition. In addition, even if we achieve the expected benefits, we may not be able to achieve them within the anticipated time frame, and such benefits may be offset by costs incurred in integrating the acquired companies and increases in other expenses.

Because we derive a significant portion of our sales from the operations of our foreign subsidiaries, future currency exchange rate fluctuations may adversely affect our results of operations and financial condition, and may affect the comparability of our results between financial periods.

For the year ended December 31, 2010, the operations in our European and International segments accounted for approximately 52% of our net sales. The results of our foreign operations are reported in the local currency and then translated into U.S. dollars at the applicable exchange rates for inclusion in our consolidated financial statements. The exchange rates between some of these currencies and the U.S. dollar have fluctuated significantly in recent years, and may continue to do so in the future. In addition, because our financial statements are stated in U.S. dollars, such fluctuations may affect our results of operations and financial position, and may affect the comparability of our results between financial periods. We cannot assure you that we will be able to effectively manage our exchange rate risks or that any volatility in currency exchange rates will not have a materially adverse effect on our results of operations and financial condition.

Our continued success depends on our ability to protect our intellectual property. If we are unable to protect our intellectual property, our business could be materially and adversely affected.

Our success depends, in part, on our ability to obtain and enforce patents, maintain trade secret protection and operate without infringing on the proprietary rights of third parties. We have been issued patents and have registered trademarks with respect to many of our products, but our competitors could independently develop similar or superior products or technologies, duplicate any of our designs, trademarks, processes or other intellectual property or design around any processes or designs on which we have or may obtain patents or

trademark protection. In addition, it is possible that third parties may have, or will acquire, licenses for patents or trademarks that we may use or desire to use, so that we may need to acquire licenses to, or to contest the validity of, such patents or trademarks of third parties. Such licenses may not be made available to us on acceptable terms, if at all, and we may not prevail in contesting the validity of third party rights.

In addition to patent and trademark protection, we also protect trade secrets, know-how, and other confidential information against unauthorized use by others or disclosure by persons who have access to them, such as our employees, through contractual arrangements. These agreements may not provide meaningful protection for our trade secrets, know-how or other proprietary information in the event of any unauthorized use, misappropriation or disclosure of such trade secrets, know-how or other proprietary information. If we are unable to maintain the proprietary nature of our technologies, our results of operations and financial condition could be materially and adversely affected.

Item 3. Legal Proceedings

We categorize the product liability losses that we experience into two main categories, single incident and cumulative trauma. Single incident product liability claims are discrete incidents that are typically known to us when they occur and involve observable injuries and, therefore, more quantifiable damages. Therefore, we maintain a reserve for single incident product liability claims, based on expected settlement costs for pending claims and an estimate of costs for unreported claims derived from experience, sales volumes, and other relevant information. The reserve for single incident product liability claims was $5.2 million and $5.9 million at December 31, 2010 and 2009, respectively. Single incident product liability expense during the years ended December 31, 2010, 2009 and 2008 was $0.2 million, $0.5 million, and $2.7 million, respectively. We evaluate our single incident product liability exposures on an ongoing basis and make adjustments to the reserve as new information becomes available.

Cumulative trauma product liability claims involve exposures to harmful substances (e.g., silica, asbestos, and coal dust) that occurred many years ago and may have developed over long periods of time into diseases such as silicosis, asbestosis, or coal worker’s pneumoconiosis. We are presently named as a defendant in approximately 1,900 lawsuits in which plaintiffs allege to have contracted certain cumulative trauma diseases related to exposure to silica, asbestos, and/or coal dust. These lawsuits mainly involve respiratory protection products allegedly manufactured and sold by us. We are unable to estimate total damages sought in these lawsuits as they generally do not specify the injuries alleged, the amount of damages sought, and potentially involve multiple defendants.

Cumulative trauma product liability litigation is difficult to predict. In our experience, until late in a lawsuit, we cannot reasonably determine whether it is probable that any given cumulative trauma lawsuit will ultimately result in a liability. This uncertainty is caused by many factors, including the following: cumulative trauma complaints generally do not provide information sufficient to determine if a loss is probable; cumulative trauma litigation is inherently unpredictable and information is often insufficient to determine if a lawsuit will develop into an actively litigated case; and even when a case is actively litigated, it is often difficult to determine if the lawsuit will be dismissed or otherwise resolved until late in the lawsuit. Moreover, even once it is probable that such a lawsuit will result in a loss, it is difficult to reasonably estimate the amount of actual loss that will be incurred. These amounts are highly variable and turn on a case-by-case analysis of the relevant facts, which are often not learned until late in the lawsuit.

Because of these factors, we cannot reliably determine our potential liability for such claims until late in the lawsuit. We, therefore, do not record cumulative trauma product liability losses when a lawsuit is filed, but rather, when we learn sufficient information to determine that it is probable that we will incur a loss and the amount of loss can be reasonably estimated. We record expenses for defense costs associated with open cumulative trauma product liability lawsuits as incurred.

We cannot estimate any amount or range of possible losses related to resolving pending and future cumulative trauma product liability claims that we may face because of the factors described above. As new information about cumulative trauma product liability cases and future developments becomes available, we reassess our potential exposures.

A summary of cumulative trauma product liability claims activity follows:


	2010			2009			2008
Open claims, January 1		2,480			2,550			2,450
New claims		260			220			320
Settled and dismissed claims		(840	)		(290	)		(220	)

Open claims, December 31		1,900			2,480			2,550

With some common contract exclusions, we maintain insurance for cumulative trauma product liability claims. We have purchased insurance policies from over 20 different insurance carriers that provide coverage for cumulative trauma product liability losses and related defense costs. In the normal course of business, we make payments to settle product liability claims and for related defense costs. We record receivables for the amounts that are covered by insurance. The available limits of these policies are many times our recorded insurance receivable balance.

Various factors could affect the timing and amount of recovery of our insurance receivables, including the outcome of negotiations with insurers, legal proceedings with respect to product liability insurance coverage, and the extent to which insurers may become insolvent in the future.

Our insurance receivables totaled $89.0 million December 31, 2010, all of which is reported in other non-current assets, and $91.7 million at December 31, 2009, of which $29.0 million is reported in other current assets and $62.7 million in other non-current assets.

A summary of insurance receivable balances and activity related to cumulative trauma product liability losses follows:


(In millions)	2010			2009			2008
Balance January 1	$	91.7		$	60.6			39.1
Additions		30.9			33.1			22.8
Collections and settlements		(33.6	)		(2.0	)		(1.3	)

Balance December 31		89.0			91.7			60.6

Additions to insurance receivables in the above table represent insured cumulative trauma product liability settlements and related defense costs. Uninsured cumulative trauma product liability losses during the years ended December 31, 2010, 2009, and 2008 were $0.2 million, $1.7 million, and $1.6 million, respectively.

Our aggregate cumulative trauma product liability settlement, administrative and defense costs for the years ended December 31, 2010, 2009, and 2008 total approximately $90.3 million, substantially all of which was insured.

We believe that the increase in the insurance receivable balance that we have experienced since 2005 is primarily due to disagreements among our insurance carriers, and consequently with us, as to when their individual obligations to pay us are triggered and the amount of each insurer’s obligation, as compared to other insurers. We believe that our insurers do not contest that they have issued policies to us or that these policies cover cumulative trauma product liability claims. Our ability to resolve our insurance litigations with Century Indemnity Company and Columbia Casualty Company successfully during 2010 demonstrates that we had strong legal positions concerning our rights to coverage.

We regularly evaluate the collectability of the insurance receivables and record the amounts that we conclude are probable of collection. Our conclusion is based on our analysis of the terms of the underlying insurance policies, our experience in successfully recovering cumulative trauma product liability claims from our insurers under other policies, the financial ability of our insurance carriers to pay the claims, our understanding and interpretation of the relevant facts and applicable law, and the advice of legal counsel, who believe that our insurers are required to provide coverage based on the terms of the policies.

Although the outcome of cumulative trauma product liability matters cannot be predicted with certainty and unfavorable resolutions could materially affect our results of operations on a quarter-to-quarter basis, based on information currently available and the amounts of insurance coverage available to us, we believe that the disposition of cumulative trauma product liability lawsuits that are pending against us will not have a materially adverse effect on our future results of operations, financial condition, or liquidity.

We are currently involved in coverage litigation with The North River Insurance Company (North River). We have sued North River in the United States District Court for the Western District of Pennsylvania, alleging that North River breached one insurance policy by failing to pay amounts owing to us and that its refusal to pay constitutes bad faith. The case was assigned to the Court’s mandatory Alternative Dispute Resolution program, in an attempt to resolve the dispute. The mediation was unsuccessful and the case will proceed to trial. We believe that North River’s refusal to indemnify us under the policy for settlements and legal fees paid by us is wholly contrary to Pennsylvania law and we are vigorously pursuing the legal actions necessary to collect all amounts.

On April 9, 2010, North River filed a complaint against us and two excess insurance carriers in the Court of Common Pleas of Allegheny County, Pennsylvania seeking a declaratory judgment concerning their responsibilities under three additional policies shared with Northbrook Insurance Company. We filed a motion to dismiss the declaratory judgment claim and a counter claim for breach of contract against North River and the two excess carriers. The court stayed the declaratory judgment claim and the breach of contract claim is now in discovery. We believe that Pennsylvania law supports our position that North River has insurance responsibilities to indemnify us against various product liability claims to the full limits of these policies.

During May 2010, we resolved the coverage litigation with Century Indemnity Company through a negotiated settlement. As part of this settlement, both parties dismissed all claims against one another under the previously-filed coverage litigation. The settlement did not have an impact on our operating results.

During July 2010, we resolved the coverage litigation with Columbia Casualty Company through a negotiated settlement. As part of this settlement, both parties dismissed all claims against one another under the previously-filed coverage litigation. The settlement did not have an impact on our operating results.

On July 26, 2010, we filed a complaint in the Superior Court of the State of Delaware seeking declaratory and other relief from the majority of our excess insurance carriers concerning the future rights and obligations of MSA and our excess insurance carriers under various insurance policies. The reason for this insurance coverage action is to secure a comprehensive resolution of our rights under the insurance policies issued by our insurers.

In December 2010, North River filed a motion to dismiss or stay the Delaware action asserting that the previously-discussed cases in the United States District Court for the Western District of Pennsylvania and the Court of Common Pleas of Allegheny County, Pennsylvania were capable of resolving the claims presented in the Superior Court of the State of Delaware action.

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

The following discussion and analysis should be read in conjunction with the historical financial statements and other financial information included elsewhere in this annual report on Form 10-K. This discussion may contain forward-looking statements that involve risks and uncertainties. The forward-looking statements are not historical facts, but rather are based on current expectations, estimates, assumptions, and projections about our industry, business, and future financial results. Our actual results could differ materially from the results contemplated by these forward-looking statements due to a number of factors, including those discussed in the sections of this annual report entitled “Forward-Looking Statements” and “Risk Factors.”

BUSINESS OVERVIEW

We are a global leader in the development, manufacture and supply of products that protect people’s health and safety. Our safety products typically integrate any combination of electronics, mechanical systems, and advanced materials to protect users against hazardous or life threatening situations. Our comprehensive lines of safety products are used by workers around the world in the fire service, homeland security, oil and gas, construction, and other industries, as well as the military.

We are committed to providing our customers with service unmatched in the safety industry and, in the process, enhancing our ability to provide a growing line of safety solutions for customers in key global markets. Four strategic imperatives drive us toward our goal of building customer loyalty by delivering exceptional levels of protection, quality, and value:

•

Achieve sustainable growth through product leadership;

•

Expand market penetration through exceptional customer focus;

•

Control costs and increase efficiency in asset utilization; and

•

Build the depth, breadth, and diversity of our global team.

We tailor our product offerings and distribution strategy to satisfy distinct customer preferences that vary across geographic regions. We believe that we best serve these customer preferences by organizing our business into three reportable geographic segments: North America, Europe, and International. Each segment includes a number of operating companies. In 2010, approximately 48%, 26%, and 26% of our net sales were made by our North American, European, and International segments, respectively.

North America. Our largest manufacturing and research and development facilities are located in the United States. We serve our North American markets with sales and distribution functions in the U.S., Canada, and Mexico.

Europe. Our European segment includes companies in most Western European countries and a number of Eastern European and Middle Eastern locations. Our largest European companies, based in Germany and France, develop, manufacture, and sell a wide variety of products. Operations in other European countries focus primarily on sales and distribution in their respective home country markets. While some of these companies may perform limited production, most of their sales are of products that are manufactured in our plants in China, Germany, France, and the U.S., or are purchased from third party vendors.

International. Our International segment includes companies in South America, Africa and the Asia Pacific region, some of which are in developing regions of the world. Principal International segment manufacturing operations are located in Australia, Brazil, China, and South Africa. These companies develop and manufacture products that are sold primarily in each company’s home country and regional markets. The other companies in the International segment focus primarily on sales and distribution in their respective home country markets. While some of these companies may perform limited production, most of their sales are of products that are manufactured in our plants in China, Germany, France, and the U.S., or are purchased from third party vendors.

ACQUISITIONS

On October 13, 2010, we strengthened our presence in oil, gas and petrochemical markets by acquiring General Monitors, Inc. (GMI) of Lake Forest, California and its affiliated companies, General Monitors Ireland Limited (GMIL) and General Monitors Transational, LLC (GMT), collectively referred to as General Monitors. General Monitors is a leading innovator and developer of advanced flame and gas detection systems that are used in a broad range of oil and gas exploration and refining applications and in diverse industrial plant settings. In addition to providing us with greater access to the global oil and gas market, we believe the acquisition significantly enhances our long-term corporate strategy in fixed gas detection by providing us with world-class research and development talent and an industry leading product line. We have assembled a joint cross functional integration team to ensure the successful integration of our operations.

During the year ended December 31, 2010, we saw growing demand in oil and gas and other core industrial markets, resulting in higher shipments of instruments, head protection and respirators, up $32.0 million, $13.0 million, and $5.8 million, respectively. Higher instrument sales in 2010 included $12.1 million in General Monitors product sales following the mid-October acquisition. These increases were partially offset by lower sales of SCBAs and gas masks, down $14.6 million and $6.0 million, respectively, on continued weakness in the fire service, law enforcement, and homeland security markets. Sales of the Advanced Combat Helmet (ACH) were $3.4 million lower in the current year, as we completed one contract and transitioned to a new contract.

Net sales of our European segment were $251.1 million for the year ended December 31, 2010, a decrease of $6.8 million, or 3%, from $257.9 million for the year ended December 31, 2009. Local currency sales in Europe increased $1.9 million for the year ended December 31, 2010. The increase occurred primarily in Western Europe where sales were up $5.9 million, on higher instrument sales to oil and gas and other core industrial market. Higher instrument sales in 2010 included $4.2 million in General Monitors product sales. This increase was partially offset by a $4.1 million decrease in sales in Eastern Europe and the Middle East in the current period, reflecting lower shipments of fire helmets and SCBAs on weakness in the fire service market. Unfavorable translation effects of weaker European currencies, particularly the euro, in the current year decreased European segment sales, when stated in U.S. dollars, by approximately $8.7 million.

Net sales of our International segment were $261.5 million for the year ended December 31, 2010, an increase of $44.0 million, or 20%, compared to $217.5 million for the year ended December 31, 2009. Local currency sales in the International segment increased $23.6 million during the year ended December 31, 2010 on higher sales of head, eye and face protection, instruments and other products, primarily in Latin American mining markets. Currency translation effects increased International segment sales, when stated in U.S. dollars, by $20.4 million, reflecting a strengthening of the Australian dollar, South African rand, and Brazilian real.

Cost of products sold. Cost of products sold was $606.5 million for the year ended December 31, 2010, an increase of $33.2 million, or 6%, from $573.3 million for the year ended December 31, 2009. Cost of products sold in 2010 includes $2.5 million in incremental purchase accounting charges related to the fair value of General Monitors inventory at the acquisition date.

Cost of products sold and operating expenses include net periodic pension benefit costs and credits. Pension credits, combined with pension costs, resulted in net pension credits for the year ended December 31, 2010 of $7.3 million, of which credits of approximately $5.3 million, $1.0 million, and $1.0 million were included in cost of products sold, selling, general and administrative expenses, and research and development expenses, respectively. Pension credits, combined with pension costs, resulted in net pension credits for the year ended December 31, 2009 of $9.1 million, of which credits of approximately $5.7 million, $1.7 million and $1.7 million were included in cost of products sold, selling, general and administrative expenses, and research and

development expenses, respectively. Future net pension credits can be volatile depending on the future performance of plan assets, changes in actuarial assumptions regarding such factors as the selection of discount rates and rates of return on plan assets, changes in the amortization levels of actuarial gains and losses, plan amendments affecting benefit pay-out levels, and profile changes in the participant populations being valued. Changes in any of these factors could cause net pension credits to change. To the extent net pension credits decline in the future, our net income would be adversely affected.

Gross profit. Gross profit for the year ended December 31, 2010 was $370.1 million, an increase of $33.4 million, or 10%, from $336.7 million for the year ended December 31, 2009. The ratio of gross profit to sales was 37.9% in 2010 compared to 37.0% in 2009. The higher gross profit ratio in the current period was primarily related to sales mix, the favorable effect of cost control initiatives and higher production volumes.

Selling, general and administrative expenses. Selling, general and administrative expenses for the year ended December 31, 2010 were $262.9 million, an increase of $32.0 million, or 14%, from $230.9 million for the year ended December 31, 2009. Selling, general and administrative expenses were 26.9% of sales in 2010 compared to 25.4% of sales in 2009. Selling, general and administrative expenses in 2010 included $6.5 million of transaction and integration expenses related to the General Monitors acquisition. North American segment selling general and administrative expenses were up $13.2 million. The increase included General Monitors selling, general and administrative expenses of $3.9 million following the mid-October acquisition. The remainder of the increase in North American segment selling, general and administrative expenses was primarily related to higher selling expenses on the higher sales volumes. Local currency selling, general and administrative expenses in the European segment were up $2.7 million. The increase includes General Monitors selling, general, and administrative expenses of $0.6 million. The remainder of the increase in European segment selling general and administrative expenses related to higher sales in Western Europe. Local currency selling, general and administrative expenses in the International segment increased $7.1 million, primarily to support the increased sales volume. Currency exchange effects increased European and International segment administrative expenses for the year ended December 31, 2010, when stated in U.S. dollars, by $2.5 million, primarily related to the strengthening of the Australian dollar, South African rand, and Brazilian real, partially offset by the weakening of the euro.

Research and development expenses. Research and development expenses were $32.8 million for the year ended December 31, 2010, an increase of $4.0 million, or 14%, from $28.8 million for the year ended December 31, 2009. The increase includes $0.7 million of General Monitors research and development expense. The remainder of the increase occurred in North America and Europe and reflects our ongoing focus on developing innovative new products.

Restructuring and other charges. Restructuring and other charges were $14.1 million for the year ended December 31, 2010, compared to $11.4 million for the year ended December 31, 2009.

For the year ended December 31, 2010, North American segment charges of $3.8 million included stay bonuses and other costs associated with our initiative to reduce operating costs by moving certain production and administrative activities. European segment charges of $8.8 million related primarily to a focused voluntary retirement incentive program in Germany (German VRIP). During the first quarter of 2010, 27 employees made irrevocable elections to retire under the terms of the German VRIP. German VRIP termination benefit expense of $5.0 million was recorded in March 2010. The remaining $3.8 million European segment charges related primarily to staff reductions and our ongoing efforts to reorganize our European operations. International segment charges of $1.5 million were primarily for severance costs related to staff reductions in South Africa and China.

For the year ended December 31, 2009, North American segment charges of $9.6 million were related primarily to a focused voluntary retirement incentive program (North American VRIP). During January 2009, 61 North American segment employees made irrevocable elections to retire under the terms of the VRIP. VRIP non-cash special termination benefits expense of $6.7 million was recorded in January 2009. The remaining $2.9

million of North American segment charges related to costs associated with layoffs and stay bonuses and other costs related to our ongoing initiative to transfer certain production activities. European and International segment charges of $0.8 million and $1.0 million, respectively, were primarily severance costs related to staff reductions in Germany, Brazil, Australia and South Africa.

Interest expense. Interest expense for the year ended December 31, 2010 was $8.7 million, an increase of $1.6 million, or 23%, from $7.1 million for the year ended December 31, 2009. The increase was related to the higher borrowings associated with the acquisition of General Monitors.

Income tax provision. Our effective tax rate for the year ended December 31, 2010 was 31.9% compared to 33.7% for the year ended December 31, 2009. The lower effective tax rate for the year was primarily related to the research and development credit and domestic production deduction in the U.S.

Net income attributable to Mine Safety Appliances Company. Net income for the year ended December 31, 2010 was $38.1 million, a decrease of $5.2 million, or 12%, from net income for the year ended December 31, 2009 of $43.3 million. Basic earnings per share of common stock was $1.06 in 2010, compared to $1.21 in 2009.

North American segment net income for the year ended December 31, 2010 was $34.6 million, a decrease of $0.4 million, or 1%, from $35.0 million for the year ended December 31, 2009. Flat net income reflects improved sales, substantially offset by higher selling, general and administrative expenses required to support sales growth.

The European segment reported a net loss for the year ended December 31, 2010 of $7.6 million, a decrease of $9.9 million, compared to net income of $2.3 million for the year ended December 31, 2009. The decrease in European segment results for the current year was primarily due to lower sales and the previously discussed increase in restructuring expenses. Currency translation effects reduced the 2010 European segment net loss, when stated in U.S. dollars, by approximately $1.1 million.

International segment net income for the year ended December 31, 2010 was $14.0 million, an increase of $8.9 million, or 175%, from $5.1 million for the year ended December 31, 2009. Higher net income was primarily related to improved sales and gross margins, partially offset by higher selling expenses.

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

Net sales. Net sales for the year ended December 31, 2009 were $910.0 million, a decrease of $224.3 million, or 20%, from $1,134.3 million for the year ended December 31, 2008.


	2009		2008		Dollar Decrease			Percent Decrease
	*(In millions)*
North America	$	434.6	$	596.3	$	(161.7	)		(27	%)
Europe		257.9		301.4		(43.5	)		(14	)
International		217.5		236.6		(19.1	)		(8	)

Net sales of our North American segment were $434.6 million for the year ended December 31, 2009, a decrease of $161.7 million, or 27%, compared to $596.3 million for the year ended December 31, 2008. Sales of Self-Contained Breathing Apparatus (SCBA) were $58.0 million lower during the current year. SCBA sales during 2008 included $54.1 million in shipments of our Firehawk^® M7 Responder to the U.S. Air Force.

Excluding these shipments, SCBA sales were $3.9 million lower in the current year. Shipments of SCBAs to the fire service market were unusually high during the first quarter of 2008 due to an increase in orders that had been delayed in late 2007 as manufacturers and the fire service market made the transition to the new National Fire Protection Association (NFPA) standard for SCBAs. Fire service market sales of thermal imaging cameras and fire helmets were down $5.5 million in the current year. Sales of Advanced Combat Helmets to the U.S. military and CG634 helmets to the Canadian Forces were $34.9 million and $13.0 million lower, respectively, reflecting the completion of certain contracts. Shipments of head protection and fall protection were down $20.8 million and $8.5 million, respectively, as the effects of the economic recession reduced demand in construction and industrial markets. Shipments of instruments were $8.3 million lower in the current year, also due to lower demand in industrial markets.

Net sales of our European segment were $257.9 million for the year ended December 31, 2009, a decrease of $43.5 million, or 14%, from $301.4 million for the year ended December 31, 2008. Local currency sales in Europe decreased $21.0 million for the year ended December 31, 2009. In France, local currency sales were $4.9 million lower in the current year, reflecting a $7.5 million decrease in shipments of ballistic vests and helmets to the military. This decrease was partially offset by a $3.0 million increase in sales of disposable respirators, primarily in response to the swine flu epidemic. In Germany, local currency sales were $12.0 million lower for the year ended December 31, 2009, reflecting a $6.8 million decrease in shipments of gas masks, primarily to the military, and a $2.7 million decrease in instrument shipments due to reduced demand in industrial markets. Unfavorable translation effects of weaker European currencies, particularly the euro, for the year ended December 31, 2009 decreased European segment sales, when stated in U.S. dollars, by approximately $22.5 million.

Net sales of our International segment were $217.5 million for the year ended December 31, 2009, a decrease of $19.1 million, or 8%, compared to $236.6 million for the year ended December 31, 2008. Local currency sales in the International segment decreased $5.4 million during the year ended December 31, 2009. In China, local currency sales increased $12.9 million, reflecting strong shipments of SCBAs and gas masks to the Hong Kong Fire Service, as well as a continued focus on growing our business in the region. Local currency sales in Australia and Latin America were down $11.8 million and $5.9 million, respectively, primarily due to the economic recession. Currency translation effects reduced International segment sales, when stated in U.S. dollars by $13.7 million, primarily related to a weakening of the Australian dollar, South African rand, and Brazilian real.

Cost of products sold. Cost of products sold was $573.3 million for the year ended December 31, 2009, a decrease of $128.4 million, or 18%, from $701.7 million for the year ended December 31, 2008.

Cost of products sold and operating expenses include net periodic pension benefit costs and credits. Pension credits, combined with pension costs, resulted in net pension credits for the year ended December 31, 2009 of $9.1 million, of which credits of approximately $5.7 million, $1.7 million, and $1.7 million were included in cost of products sold, selling, general and administrative expenses, and research and development expenses, respectively. Pension credits, combined with pension costs, resulted in net pension credits for the year ended December 31, 2008 of $9.8 million, of which credits of approximately $7.2 million, $1.4 million and $1.2 million were included in cost of products sold, selling, general and administrative expenses, and research and development expenses, respectively.

Gross profit. Gross profit for the year ended December 31, 2009 was $336.7 million, a decrease of $95.9 million, or 22%, from $432.6 million for the year ended December 31, 2008. The decrease reflects the previously discussed reduction in sales and a lower gross profit percentage. The unfavorable translation effects of weaker foreign currencies reduced gross profit, when stated in U.S. dollars, by $15.1 million. The ratio of gross profit to sales was 37.0% in 2009 compared to 38.1% in 2008. The lower gross profit ratio in the current period occurred primarily in the European and International segments and related to sales mix, lower production volumes, and recessionary pricing pressures.

Selling, general and administrative expenses. Selling, general and administrative expenses for the year ended December 31, 2009 were $230.9 million, a decrease of $39.7 million, or 15%, from $270.6 million for the year ended December 31, 2008. Selling, general and administrative expenses were 25.4% of sales in 2009 compared to 23.9% of sales in 2008. North American segment selling, general and administrative expenses were down $18.2, or 17%. Local currency selling, general and administrative expenses in the European and International segments were down $13.3 million, or 8%, during the year ended December 31, 2009. Lower selling, general and administrative expenses for the year were the direct result of cost-savings initiatives that we took in response to the economic recession. These initiatives included selective staffing reductions, a salary and hiring freeze in the U.S. and Canada, a temporary suspension of company matching contributions to our 401k plan and temporary pay reductions for executives and senior level managers. Currency exchange effects reduced selling, general and administrative expenses, when stated in U.S. dollars, by $8.2 million, primarily due to a weaker euro, Australian dollar and Brazilian real.

Research and development expenses. Research and development expenses were $28.8 million for the year ended December 31, 2009, a decrease of $6.2 million, or 18%, from $35.0 million for the year ended December 31, 2008. The decrease reflects cost-savings realized by shifting a portion of our research and development efforts to our new China Technology Center, as well as, various other cost reduction initiatives in North America and Europe. Currency exchange effects reduced research and development expense, when stated in U.S. dollars by $0.6 million.

Restructuring and other charges. Restructuring and other charges were $11.4 million for the year ended December 31, 2009, compared to $3.9 million for the year ended December 31, 2008.

For the year ended December 31, 2009, North American segment charges of $9.6 million were related primarily to a focused voluntary retirement incentive program (VRIP). During January 2009, 61 North American segment employees made irrevocable elections to retire under the terms of the VRIP. These employees retired on January 31, 2009. VRIP non-cash special termination benefits expense totaled $6.7 million. We estimate that the staff reductions associated with the VRIP have resulted in annual pre-tax savings of approximately $5.0 million. The remaining $2.9 million of North American segment charges related to costs associated with layoffs and stay bonuses and other costs related to our ongoing initiative to transfer certain production activities. European and International segment charges of $0.8 million and $1.0 million, respectively, were primarily for severance costs related to staff reductions in Germany, Brazil, Australia and South Africa.

For the year ended December 31, 2008, North American segment charges of $3.2 million were primarily stay bonuses and other costs associated with our Project Magellan initiative to outsource or transfer certain production activities from our Evans City, Pennsylvania plant. International segment charges of $0.7 million were for severance costs related to staff reductions in Japan and India.

Interest expense. Interest expense for the year ended December 31, 2009 was $7.1 million, a decrease of $1.8 million, or 21%, from $8.9 million for the year ended December 31, 2008. The decrease in interest expense was due to reductions in both short- and long-term debt and lower short-term interest rates.

Currency exchange losses (gains). During the year ended December 31, 2009, we recorded currency exchange gains of $0.9 million compared to losses of $6.9 million for the year ended December 31, 2008. Currency exchange losses during 2008 were primarily unrealized, and related mainly to the effects of a weaker Australian dollar and Mexican peso on inter-company balances and losses on Canadian dollar trade receivables.

Income tax provision. Our effective tax rate for the year ended December 31, 2009 was 33.7% compared to 37.4% for the year ended December 31, 2008. The provision for income taxes for the year ended December 31, 2009 includes tax benefits of $0.6 million related to recognition of net operating losses in South Africa and $0.6

million related to a state tax law change. The provision for incomes taxes for the year ended December 31, 2008

included charges in Germany totaling $0.9 million related to a tax law change that imposed a 3% flat tax on previously untaxed subsidies and the settlement of a tax audit. Excluding these one-time items, the effective tax rate for the year ended December 31, 2009 was 35.5% compared to 36.6% for the year ended December 31, 2008.

Net income attributable to Mine Safety Appliances Company. Net income for the year ended December 31, 2009 was $43.3 million, a decrease of $27.1 million, or 39%, from net income for the year ended December 31, 2008 of $70.4 million. Basic earnings per share of common stock was $1.21 in 2009 compared to $1.98 in 2008.

North American segment net income for the year ended December 31, 2009 was $35.0 million, a decrease of $17.4 million, or 33%, from $52.4 million for the year ended December 31, 2008. North American segment net income for the year ended December 31, 2009 includes a $4.4 million after-tax non-cash charge related to the voluntary retirement incentive program that was completed in January and a $2.1 million after-tax gain on the sale of 25 acres in our Cranberry Woods office park. Excluding these one-time items, North American segment net income was down $15.1 million in the current year. The decrease reflects the negative effect of a 27% decrease in sales, partially offset by the positive effect of reduced operating expenses.

European segment net income for the year ended December 31, 2009 was $2.3 million, a decrease of $9.4 million, or 80%, from $11.7 million for the year ended December 31, 2008. The decrease in European segment net income during the year ended December 31, 2009 was primarily due to the previously discussed decrease in sales and gross margins. Currency translation effects decreased current period European segment net income, when stated in U.S. dollars, by approximately $1.2, largely due to the weakening of the euro.

International segment net income for the year ended December 31, 2009 was $5.1 million, a decrease of $4.7 million, or 48%, from $9.8 million for the year ended December 31, 2008. The decrease in International segment net income was primarily related to lower sales. Currency translation effects decreased current period International segment net income, when stated in U.S. dollars, by approximately $2.0, largely due to the weakening of the Australian dollar and the Brazilian real.

LIQUIDITY AND CAPITAL RESOURCES

Our main source of liquidity is operating cash flows, supplemented by borrowings to fund significant transactions. Our principal liquidity requirements are for working capital, capital expenditures, principal and interest payments on debt, and acquisitions. We believe that our financial strength has been evident during the recession and the early stages of recovery. Approximately half of our long-term debt is at fixed interest rates with manageable repayment schedules through 2021. The remainder of our long-term debt is at variable rates on an unsecured revolving credit facility that is due in 2015. Substantially all of our borrowings originate in the U.S., which has limited our exposure to non-U.S. credit markets and to currency exchange rate fluctuations.

Cash and cash equivalents decreased $2.2 million during the year ended December 31, 2010, compared to increasing $11.1 million during 2009.

Operating activities provided cash of $31.6 million in 2010, compared to providing cash of $120.8 million in 2009. Significantly lower cash provided by operations in 2010 was primarily related to changes in working capital. During the height of the recession in 2009, reductions in working capital provided $67.2 million in cash. Operating cash flow before changes in working capital was $32.9 million in 2010, compared to $53.7 million in 2009. Lower operating cash flow before changes in working capital was primarily due to lower net income and an increase in other non-current assets that was mainly related to insurance receivables. Trade receivables were $198.6 million at December 31, 2010, an increase of $25.2 million, compared to $173.4 million at December 31, 2009. LIFO inventories were $150.6 million at December 31, 2010, an increase of 26.7 million, compared to $123.9 million at December 31, 2009. The December 31, 2010 trade receivables and inventory balances included General Monitors trade receivables and inventory of $12.6 million and $13.2 million, respectively. The

remainder of the increases in trade receivables and inventory reflect the impact of higher sales and improved customer demand. Currency translation effects on trade receivables and inventory were not significant during 2010.

Investing activities used cash of $281.6 million in 2010, compared to using $20.8 million in 2009. The increased use of cash for investing activities in 2010 was related to the acquisition of General Monitors.

Financing activities provided cash of $246.6 million in 2010, compared to using cash of $91.9 million in 2009. The change was primarily related to borrowings made to finance the acquisition of General Monitors in 2010. We made dividend payments of $35.9 million during 2010, compared to $34.5 million during 2009. Dividends paid on our common stock during 2010 (our 93^rd consecutive year of dividend payment) were $0.99 per share. Dividends paid on our common stock in 2009 and 2008 were $0.96 and $0.94 per share, respectively.

CUMULATIVE TRANSLATION ADJUSTMENTS

The year-end position of the U.S. dollar relative to international currencies resulted in a translation gain of $1.6 million being credited to the cumulative translation adjustments attributable to Mine Safety Appliances Company shareholders’ equity account for the year ended December 31, 2010, compared to a gain of $17.7 million in 2009 and a loss of $23.2 million in 2008. The translation gain in 2009 reflects the strengthening of the euro, Brazilian real, Australian dollar, and South African rand. The translation loss in 2008 reflects the strengthening of the U.S. dollar against most currencies.

COMMITMENTS AND CONTINGENCIES

We are obligated to make future payments under various contracts, including debt and lease agreements. Our significant cash obligations as of December 31, 2010 were as follows:


	Total		2011		2012		2013		2014		2015		Thereafter
	*(In millions)*
Long-term debt*	$	377.1	$	9.9	$	8.2	$	6.7	$	6.7	$	201.6	$	144.0
Operating leases		25.5		9.0		5.0		3.6		2.9		2.5		2.5

Totals		402.6		18.9		13.2		10.3		9.6		204.1		146.5

*	Future interest payments are not included in the table.

The significant obligations table does not include obligations to taxing authorities due to uncertainty surrounding the ultimate settlement of amounts and timing of these obligations.

We expect to meet our 2011 through 2014 debt service obligations through cash provided by operations. Approximately $195.0 million of debt payable in 2015 relates to our unsecured senior revolving credit facility. We expect to generate sufficient operating cash flow to make payments against this amount each year. To the extent that a balance remains when the facility matures in 2015, we expect to refinance the remaining balance through new borrowing facilities.

We expect to make net contributions of $3.8 million to our pension plans in 2011.

We have purchase commitments for materials, supplies, services, and property, plant and equipment as part of our ordinary conduct of business.

In 2006, we acquired Paraclete Armor and Equipment, Inc. Under the terms of the asset purchase agreement, we issued a $10.0 million note payable to the former owners of Paraclete. The note is non-interest bearing and is payable in five annual installments of $2.0 million beginning September 1, 2007. We recorded the note at a fair value of $8.5 million at the time of issuance. The discount of $1.5 million is being amortized over the term of the note.

During 2003, we sold our real property in Berlin, Germany for $25.7 million, resulting in a gain of $13.6 million. At the same time, we entered into an eight year agreement to lease back the portion of the property that we occupy. Under sale-leaseback accounting, $12.1 million of the gain was deferred and is being amortized over the term of the lease.

A summary of cumulative trauma product liability claims activity follows:


	2010			2009			2008
Open claims, January 1		2,480			2,550			2,450
New claims		260			220			320
Settled and dismissed claims		(840	)		(290	)		(220	)

Open claims, December 31		1,900			2,480			2,550

A summary of insurance receivable balances and activity related to cumulative trauma product liability losses follows:


(In millions)	2010			2009			2008
Balance January 1	$	91.7		$	60.6			39.1
Additions		30.9			33.1			22.8
Collections and settlements		(33.6	)		(2.0	)		(1.3	)

Balance December 31		89.0			91.7			60.6

In addition to the insurance receivables reported in our balance sheet, the primary effect of the delays in reimbursement from our insurance companies has been the incremental interest expense associated with the net cash outlays and legal expenses related to insurance litigation. Legal fees and incremental interest expense associated with the delays in collection of insurance receivables averaged approximately 5% of cumulative net income during the three years ended December 31, 2010.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

We prepare our consolidated financial statements in accordance with U.S. generally accepted accounting principles (GAAP). The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and the related disclosures. We evaluate these estimates and judgments on an on-going basis based on historical experience and various assumptions that we believe to be reasonable under the circumstances. However, different amounts could be reported if we had used different assumptions and in light of different facts and circumstances. Actual amounts could differ from the estimates and judgments reflected in our financial statements.

We believe that the following are the more critical judgments and estimates used in the preparation of our financial statements.

Accounting for contingencies. We accrue for contingencies when we believe that it is probable that a liability or loss has been incurred and the amount can be reasonably estimated. Contingencies relate to

uncertainties that require our judgment both in assessing whether or not a liability or loss has been incurred and in estimating the amount of the probable loss. Significant contingencies affecting our financial statements include pending or threatened litigation, including product liability claims, and product warranties.

Product liability. We face an inherent business risk of exposure to product liability claims arising from the alleged failure of our products to prevent the types of personal injury or death against which they are designed to protect. We categorize the product liability losses that we experience into two main categories, single incident and cumulative trauma. Single incident product liability claims are discrete incidents that are typically known to us when they occur and involve observable injuries and, therefore, more quantifiable damages. We maintain a reserve for single incident product liability claims, based on expected settlement costs for pending claims and an estimate of costs for unreported claims derived from experience, sales volumes, and other relevant information. We evaluate our single incident product liability exposures on an ongoing basis and make adjustments to the reserve as new information becomes available.

Cumulative trauma product liability claims involve exposures to harmful substances that occurred many years ago and may have developed over long periods of time into diseases such as silicosis, asbestosis, or coal worker’s pneumoconiosis. In our experience, until late in a lawsuit, we cannot reasonably determine whether it is probable that any given cumulative trauma lawsuit will ultimately result in a liability. This uncertainty is caused by many factors, including the following: cumulative trauma complaints generally do not provide information sufficient to determine if a loss is probable; cumulative trauma litigation is inherently unpredictable and information is often insufficient to determine if a lawsuit will develop into an actively litigated case; and even when a case is actively litigated, it is often difficult to determine if the lawsuit will be dismissed or otherwise resolved until late in the lawsuit. Moreover, even once it is probable that such a lawsuit will result in a loss, it is difficult to reasonably estimate the amount of actual loss that will be incurred. These amounts are highly variable and turn on a case-by-case analysis of the relevant facts, which are often not learned until late in the lawsuit. We, therefore, do not record cumulative trauma product liability losses when a lawsuit is filed, but rather, when we learn sufficient information to determine that it is probable that we will incur a loss and the amount of loss can be reasonably estimated.

We cannot estimate any amount or range of possible losses related to resolving pending and future cumulative trauma product liability claims that we may face because of the factors described above. As new information about cumulative trauma product liability claims and future developments becomes available, we reassess our potential exposures.

We record expenses for defense costs associated with open product liability lawsuits as incurred.

With some common contract exclusions, we maintain insurance for single incident and cumulative trauma product liability claims and related defense costs. In the normal course of business, we make payments to settle product liability claims and for related defense costs. We record receivables for the amounts that are covered by insurance.

Due to uncertainty as to the ultimate outcome of pending and threatened claims, as well as the incidence of future claims, it is possible that future results could be materially affected by changes in our assumptions and estimates related to product liability matters, including our estimates of amounts receivable from insurance carriers. Our product liability expense averaged less than 1% of net sales during the three years ended December 31, 2010.

Product warranties. We accrue for the estimated probable cost of product warranties at the time that sales are recognized. Our estimates are principally based on historical experience. We also accrue for our estimates of the probable costs of corrective action when significant product quality issues are identified. These estimates are principally based on our assumptions regarding the cost of corrective action and the probable number of units to be repaired or replaced. Our product warranty obligation is affected by product failure rates, material usage, and

service delivery costs incurred in correcting a product failure. Due to the uncertainty and potential volatility of these factors, it is possible that future results could be materially affected by changes in our assumptions or the effectiveness of our strategies related to these matters. Our product warranty expense averaged approximately 1% of net sales during the three years ended December 31, 2010.

Income taxes. We recognize deferred tax assets and liabilities using enacted tax rates for the effect of temporary differences between the book and tax basis of recorded assets and liabilities. We record valuation allowances to reduce deferred tax assets to the amounts that we estimate are probable to be realized. When assessing the need for valuation allowances, we consider projected future taxable income and prudent and feasible tax planning strategies. Should a change in circumstances lead to a change in our judgments about the realizability of deferred tax assets in future years, we adjust the related valuation allowances in the period that the change in circumstances occurs. We had valuation allowances of $4.3 million and $3.2 million at December 31, 2010 and 2009, respectively.

We record an estimated income tax liability based on our best judgment of the amounts likely to be paid in the various tax jurisdictions in which we operate. We record tax benefits related to uncertain tax positions taken or expected to be taken on a tax return when such benefits meet a more likely than not threshold. We recognize interest related to unrecognized tax benefits in interest expense and penalties in operating expenses. The tax liabilities ultimately paid are dependent on a number of factors, including the resolution of tax audits, and may differ from the amounts recorded. Tax liabilities are adjusted through income when it becomes probable that the actual liability differs from the amount recorded.

Pensions and other postretirement benefits. We sponsor certain pension and other postretirement benefit plans. Accounting for the net periodic benefit costs and credits for these plans requires us to estimate the cost of benefits to be provided well into the future and to attribute these costs over the expected work life of the employees participating in these plans. These estimates require our judgment about discount rates used to determine these obligations, expected returns on plan assets, rates of future compensation increases, rates of increase in future health care costs, participant withdrawal and mortality rates, and participant retirement ages. Differences between our estimates and actual results may significantly affect the cost of our obligations under these plans and could cause net periodic benefit costs and credits to change materially from year-to-year. The discount rate assumptions used in determining projected benefit obligations are based on published long-term bond indices or a company-specific yield curve model.

Goodwill. Each year we evaluate for goodwill impairment by comparing the fair value of each of our reporting units with its carrying value. If carrying value exceeds fair value, then a possible impairment of goodwill exists and requires further evaluation. We estimate the fair value of our reporting units using a combination of discounted cash flow analysis and market capitalization based on historical and projected financial information. We apply our best judgment in assessing the reasonableness of the financial projections and other estimates used to determine the fair value of each reporting unit.

RECENTLY ADOPTED AND RECENTLY ISSUED ACCOUNTING STANDARDS

In December 2007, the Financial Accounting Standards Board (FASB) issued a statement that requires the recognition of a noncontrolling interest (minority interest) as equity in the consolidated financial statements and separate from the parent’s equity. The amount of net income attributable to the noncontrolling interest is to be included in consolidated net income on the face of the income statement. The statement also amended certain consolidation procedures and expanded disclosure requirements regarding the interests of the parent and its noncontrolling interest. The adoption of the new statement on January 1, 2009 is reflected in these financial statements and did not have a material effect on our consolidated results of operations or financial condition.

In March 2008, the FASB issued a statement that requires companies to provide disclosures about (a) how and why derivative instruments are used, (b) how derivative instruments and related hedged items are accounted

for, and (c) how derivative instruments and related hedged items affect the company’s financial position, financial performance, and cash flows. We adopted the new statement on January 1, 2009. See note 15 for disclosures related to derivative instruments and hedging activities.

In April 2008, the FASB issued a staff position that amends the factors that should be considered in developing renewal or extension assumptions used to determine the useful life of a recognized intangible asset. The objective of this staff position is to improve the consistency between the useful life of a recognized intangible asset and the period of expected cash flows used to measure the fair value of the asset. This staff position applies to all intangible assets, whether acquired in a business combination or otherwise, and is to be applied prospectively to intangible assets acquired on or after January 1, 2009. The adoption of this staff position did not have a material effect on our consolidated financial statements.

In April 2009, the FASB issued a staff position that requires disclosures about the fair value of financial instruments for interim reporting periods as well as in annual financial statements. We adopted this staff position for our second quarter 2009 interim reporting period. See note 17 for disclosures related to the fair value of financial instruments.

In May 2009, the FASB issued a statement that establishes general standards of accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued or are available to be issued. Specifically, the statement sets forth the period after the balance sheet date during which management of a reporting entity should evaluate events or transactions that may occur for potential recognition or disclosure in the financial statements, the circumstances under which an entity should recognize events or transactions occurring after the balance sheet date in its financial statements, and the disclosures that an entity should make about events or transactions that occurred after the balance sheet date. Our adoption of the new statement on June 30, 2009 had no impact on the financial statements as management already followed a similar approach prior to the adoption of this standard.

In June 2009, the FASB issued a statement that removes the concept of a qualifying special-purpose entity and clarifies the objective of determining whether a transferor and all of the entities included in the transferor’s financial statements being presented have surrendered control over transferred financial assets. The adoption of this statement on January 1, 2010 did not have a material effect on our consolidated financial statements.

In June 2009, the FASB issued a statement that amends the consolidation guidance applicable to variable interest entities. The adoption of this statement on January 1, 2010 did not have a material effect on our consolidated financial statements.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Market risk represents the risk of adverse changes in the value of a financial instrument caused by changes in currency exchange rates, interest rates, and equity prices. We are exposed to market risks related to currency exchange rates and interest rates.

Currency exchange rate sensitivity. We are subject to the effects of fluctuations in currency exchange rates on various transactions and on the translation of the reported financial position and operating results of our non-U.S. companies from local currencies to U.S. dollars. A hypothetical 10% strengthening or weakening of the U.S. dollar would increase or decrease our reported sales and net income for the year ended December 31, 2010 by approximately $51.3 million and $0.7 million, respectively.

When appropriate, we may attempt to limit our transactional exposure to changes in currency exchange rates through contracts or other actions intended to reduce existing exposures by creating offsetting currency exposures. At December 31, 2010, we had open foreign currency forward contracts with a U.S. dollar notional value of $19.0 million. A hypothetical 10% increase in December 31, 2010 forward exchange rates would result in a $1.9 million increase in the fair value of these contracts.

Interest rate sensitivity. We are exposed to changes in interest rates primarily as a result of borrowing and investing activities used to maintain liquidity and fund business operations. Because of the relatively short maturities of temporary investments and the variable rate nature of industrial development debt, these financial instruments are reported at carrying values which approximate fair values.

We have $176.0 million of fixed rate debt which matures at various dates through 2021. The incremental increase in the fair value of fixed rate long-term debt resulting from a hypothetical 10% decrease in interest rates would be approximately $3.5 million. However, our sensitivity to interest rate declines and the corresponding increase in the fair value of our debt portfolio would unfavorably affect earnings and cash flows only to the extent that we elected to repurchase or retire all or a portion of our fixed rate debt portfolio at prices above carrying values.

Management’s Report on Responsibility for Financial Reporting

Management of Mine Safety Appliances Company (the Company) is responsible for the preparation of the financial statements included in this annual report. The financial statements were prepared in accordance with accounting principles generally accepted in the United States of America and include amounts that are based on the best estimates and judgments of management. The other financial information contained in this annual report is consistent with the financial statements.

Management’s Report on Internal Control Over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting. The 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.

The Company’s internal control over financial reporting includes policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect transactions and dispositions of assets; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures are being made only in accordance with authorizations of management and the directors of the Company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on our 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.

Management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2010. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework. Based on our assessment and those criteria, management has concluded that the Company maintained effective internal control over financial reporting as of December 31, 2010.

The effectiveness of the Company’s 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 herein.

Management excluded General Monitors, Inc., General Monitors Ireland Limited and General Monitors, LLC, collectively referred to as General Monitors, from its assessment of internal control over financial reporting as of December 31, 2010, because they were acquired by the Company in purchase business combinations during 2010. The General Monitors companies are wholly-owned subsidiaries, whose excluded aggregate assets represent 4.8% and whose excluded total revenues represent 1.7% of the related consolidated financial statement amounts as of and for the year ended December 31, 2010.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors of Mine Safety Appliances Company:

In our opinion, the accompanying consolidated balance sheets and related consolidated statements of income, cash flows and changes in retained earnings and other comprehensive income present fairly, in all material respects, the financial position of Mine Safety Appliances Company and its subsidiaries (the “Company”) 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. In addition, in our opinion, the financial statement schedule appearing in Item 15. Exhibits and Financial Statement Schedules (a) 2. presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. 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 and financial statement schedule, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control over Financial Reporting appearing under Item 8. Our responsibility is to express opinions on these financial statements, on the financial statement schedule, 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.

As described in Management’s Report on Internal Control Over Financial Reporting appearing under Item 8, management has excluded General Monitors, Inc. (GMI) and its affiliated companies, General Monitors Ireland Limited (GMIL) and General Monitors Transnational, LLC (GMT), collectively referred to as General Monitors, from its assessment of internal control over financial reporting as of December 31, 2010, because these entities were acquired by the Company in purchase business combinations during 2010. We have also excluded General Monitors from our audit of internal control over financial reporting. General Monitors’ aggregate total assets and aggregate total revenues represent 4.8% and 1.7% respectively, of the related consolidated financial statement amounts as of and for the year ended December 31, 2010.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1—Significant Accounting Policies

Use of Estimates—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 reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Principles of Consolidation—The consolidated financial statements include the accounts of the company and all subsidiaries. Intercompany accounts and transactions are eliminated. Certain prior year amounts have been reclassified to conform with the current year presentation.

Noncontrolling Interests—Noncontrolling interests reflect noncontrolling shareholders’ original investments in certain consolidated subsidiaries and their proportionate share of the income and accumulated other comprehensive income of those subsidiaries.

Currency Translation—The functional currency of all significant non-U.S. subsidiaries is the local currency. Assets and liabilities of these operations are translated at year-end exchange rates. Income statement accounts are translated using the average exchange rates for the reporting period. Translation adjustments for these companies are reported as a component of shareholders’ equity and are not included in income. Foreign currency transaction gains and losses are included in net income for the reporting period.

Cash Equivalents—Cash equivalents include temporary deposits with financial institutions and highly liquid investments with original maturities of 90 days or less.

Inventories—Inventories are stated at the lower of cost or market. U.S. inventories are valued on the last-in, first-out (LIFO) cost method. Other inventories are valued on the average cost method or at standard costs which approximate actual costs.

Property and Depreciation—Property is recorded at cost. Depreciation is computed using straight-line and accelerated methods over the estimated useful lives of the assets, generally as follows: buildings 20 to 40 years and machinery and equipment 3 to 10 years. Expenditures for significant renewals and improvements are capitalized. Ordinary repairs and maintenance are expensed as incurred. Gains or losses on property dispositions are included in income and the cost and related depreciation are removed from the accounts.

Goodwill and Other Intangible Assets—Goodwill is not amortized, but is subject to impairment write-down tests. We test the goodwill of each of our reporting units for impairment at least annually. The annual goodwill impairment tests are performed as of September 30 each year. For this purpose, we consider our operating segments to be our reporting units. Fair value is estimated using discounted cash flow methodologies and market comparable information. Intangible assets are amortized on a straight-line basis over their useful lives.

Revenue Recognition—Revenue from the sale of products is recognized when title, ownership, and the risk of loss have transferred to the customer, which generally occurs either when product is shipped to the customer or, in the case of most U.S. distributor customers, when product is delivered to the customer’s delivery site. We establish our shipping terms according to local practice and market characteristics. We do not ship product unless we have an order or other documentation authorizing shipment to our customers. We make appropriate provisions for uncollectible accounts receivable and product returns, both of which have historically been insignificant in relation to our net sales. Certain distributor customers receive price rebates based on their level of purchases and other performance criteria that are documented in established distributor programs. These rebates are accrued as a reduction of net sales as they are earned by the customer.

MINE SAFETY APPLIANCES COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Shipping and Handling—Shipping and handling expenses for products sold to customers are charged to cost of products sold as incurred. Amounts billed to customers for shipping and handling are included in net sales.

Product Warranties—Estimated expenses related to product warranties and additional service actions are charged to cost of products sold in the period in which the related revenue is recognized or when significant product quality issues are identified.

Research and Development—Research and development costs are expensed as incurred.

Income Taxes—Deferred income taxes are provided for temporary differences between financial and tax reporting. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. If it is more likely than not that some portion or all of a deferred tax asset will not be realized, a valuation allowance is recognized. We record tax benefits related to uncertain tax positions taken or expected to be taken on a tax return when such benefits meet a more likely than not threshold. We recognize interest related to unrecognized tax benefits in interest expense and penalties in operating expenses. No provision is made for possible U.S. taxes on the undistributed earnings of foreign subsidiaries that are considered to be reinvested indefinitely.

Stock-Based Compensation—We account for stock-based compensation in accordance with the FASB guidance on share-based payment, which requires that we recognize compensation expense for employee and non-employee director stock-based compensation based on the grant date fair value. Except for retirement-eligible participants, for whom there is no requisite service period, this expense is recognized ratably over the requisite service periods following the date of grant. For retirement-eligible participants, this expense is recognized at the grant date.

Derivative Instruments—We may use derivative instruments to minimize the effects of changes in currency exchange rates and to achieve a targeted mix of fixed and floating interest rates on outstanding debt. We do not enter into derivative transactions for speculative purposes and do not hold derivative instruments for trading purposes. Changes in the fair value of derivative instruments designated as fair value hedges are recorded in the balance sheet as adjustments to the underlying hedged asset or liability. Changes in the fair value of derivative instruments that do not qualify for hedge accounting treatment are recognized in the income statement in the current period.

Note 2—Restructuring and Other Charges

During the years ended December 31, 2010 and 2009, we recorded charges of $14.1 million and $11.4 million, respectively. These charges were primarily related to reorganization activities.

For the year ended December 31, 2010, European segment charges of $8.8 million related primarily to a focused voluntary retirement incentive program in Germany (German VRIP). During the first quarter of 2010, 27 employees made irrevocable elections to retire under the terms of the German VRIP. German VRIP termination benefit expense of $5.0 million was recorded in March 2010. The remaining $3.8 million European segment charges related to costs associated with staff reductions and our ongoing efforts to reorganize our European operations. North American segment charges for the year ended December 31, 2010 of $3.8 million included stay bonuses and other costs associated with our initiative to transfer certain production and administrative activities. International segment charges for the year ended December 31, 2010 of $1.5 million were primarily related to severance costs associated with staff reductions in South Africa and China.

MINE SAFETY APPLIANCES COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

For the year ended December 31, 2009, North American segment charges of $9.6 million related primarily to a focused voluntary retirement incentive program (North American VRIP). During January 2009, 61 North American segment employees made irrevocable elections to retire under the terms of the North American VRIP. North American VRIP non-cash special termination benefits expense of $6.7 million was recorded in January 2009. The remaining $2.9 million of North American segment charges related to costs associated with layoffs, stay bonuses, and our ongoing initiative to transfer certain production activities. European and International segment charges for the year ended December 31, 2009 of $0.8 million and $1.0 million, respectively, were primarily for severance costs related to staff reductions in Germany, Brazil, Australia and South Africa.

Inventories stated on the LIFO basis represent 22% and 18% of total inventories at December 31, 2010 and 2009, respectively.

Reductions in certain inventory quantities during the years ended December 31, 2010 and 2009 resulted in liquidations of LIFO inventories carried at lower costs prevailing in prior years. The effect of LIFO liquidations during 2010 was not significant. The effect of LIFO liquidations during 2009 reduced cost of sales by $2.5 million and increased net income by $1.6 million.

The Mine Safety Appliances Company Stock Compensation Trust was established to provide shares for certain benefit plans, including the management and non-employee directors’ equity incentive plans. Shares held by the Stock Compensation Trust, and the corresponding cost of those shares, are reported as a reduction of common shares issued. Differences between the cost of the shares held by the Stock Compensation Trust and the market value of shares released for stock-related benefits are reflected in common stock issued.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

In 2010, we changed the composition of our European and International segments to reflect new management responsibilities. Under the new structure, our operations in the Middle East, Egypt and India are reported in the European segment. Previously these operations were reported in the International segment. Comparative prior year amounts have been revised to conform to the current year presentation. The effect of the revisions for 2009 increased European segment sales and net income by $19.4 million and $2.2 million, respectively, and decreased International segment sales and net income by the corresponding amounts. The effect for 2008 increased European segment sales and net income by $20.8 million and $2.0 million, respectively, and decreased International segment sales and net income by the corresponding amounts.

At December 31, 2010, we had net operating loss carryforwards of approximately $34.0 million, all in non-U.S. tax jurisdictions. A portion of the net operating loss carryforwards will expire in 2013 and a portion may be carried forward indefinitely.

No deferred U.S. income taxes have been provided on undistributed earnings of non-U.S. subsidiaries, which amounted to $211.8 million as of December 31, 2010. These earnings are considered to be reinvested for an indefinite period of time. It is not practicable to determine the deferred tax liability on these undistributed earnings.

A reconciliation of the change in the tax liability for unrecognized tax benefits for the years ended December 31, 2010 and December 31, 2009 is as follows:

MINE SAFETY APPLIANCES COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

The total amount of unrecognized tax benefits, if recognized, would reduce our future effective tax rate. We have recognized tax benefits associated with these liabilities in the amount of $10.5 million and $7.4 million at December 31, 2010 and December 31, 2009, respectively.

We recognize interest related to unrecognized tax benefits in interest expense and penalties in operating expenses. As a result of the adoption of the FASB interpretation on accounting for uncertainty in income taxes, we recognized a $0.9 million increase in the liability for accrued interest and penalties related to uncertain tax positions, which were also accounted for as a reduction of retained earnings at January 1, 2007. During 2010, we accrued additional interest and penalties related to uncertain tax positions of $0.3 million. As a result of settlements and additional uncertain tax positions, we reversed a net amount of $0.4 million of accrued interest and penalties related to uncertain tax positions for years prior to 2010. Our liability for accrued interest and penalties related to uncertain tax positions was $0.8 million at December 31, 2010.

We file a U.S. federal income tax return along with various state and foreign income tax returns. Examinations of our federal returns have been completed through 2006. Various state and foreign income tax returns may be subject to tax audits after 2005.

Note 8—Stock Plans

In May 2008, the shareholders approved the 2008 Management Equity Incentive Plan and the 2008 Non-Employee Directors’ Equity Incentive Plan. These plans replaced the 1998 Management Share Incentive Plan and the 1990 Non-Employee Directors’ Stock Option Plan. The 2008 Management Equity Incentive Plan provides for various forms of stock-based compensation for eligible key employees through May 2018. Management stock-based compensation includes stock options, restricted stock and, beginning in 2009, performance stock units. The 2008 Non-Employee Directors’ Equity Incentive Plan provides for grants of stock options and restricted stock to non-employee directors through May 2018. Stock options are granted at market value option prices and expire after ten years, with limited instances of option prices in excess of market value and expiration after five years. Stock options are exercisable beginning three years after the grant date. Restricted stock is granted without payment to the company and generally vests three years after the grant date. Certain restricted stock for management retention vests in three equal tranches four, five, and six years after the grant date. Unvested restricted stock for management retention is forfeited if the grantee’s employment with the company terminates for any reason other than death or disability. Restricted stock is valued at the market value of the stock on the grant date. Performance stock units are valued at the market value of the stock on the grant date. The final number of shares to be issued for performance stock units may range from zero to 200% of the target award based on achieving a targeted return on net assets (RONA) over a three year performance period relative to a pre-determined peer group of companies.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

We did not capitalize any stock-based compensation expense in 2010, 2009, or 2008.

Stock option expense is based on the fair value of stock option grants estimated on the grant dates using the Black-Scholes option pricing model and the following weighted average assumptions for options granted in 2010, 2009, and 2008.


	2010			2009			2008
Fair value per option	$	7.21		$	5.80		$	16.10
Risk-free interest rate		3.0	%		2.2	%		3.3	%
Expected dividend yield		3.9	%		3.0	%		1.9	%
Expected volatility		40	%		42	%		40	%
Expected life (years)		6.1			6.1			6.1

The risk-free interest rate is based on the U.S. Treasury Constant Maturity rates as of the grant date converted into an implied spot rate yield curve. Expected dividend yield is based on the most recent annualized dividend divided by the one year average closing share price. Expected volatility is based on the ten year historical volatility using daily stock prices. Expected life is based on historical stock option exercise data.

On October 13, 2010, we entered into a credit agreement with a syndicate of lenders establishing a $250.0 million unsecured senior revolving credit facility that matures in October 2015. The senior revolving credit facility provides for borrowings up to $250.0 million and is subject to certain commitment fees. Loans made under the senior revolving credit facility bear interest at a variable rate. Loan proceeds may be used for general corporate purposes, including working capital, permitted acquisitions, capital expenditures and repayment of existing indebtedness. The credit agreement also provides for an uncommitted incremental facility that permits us, subject to certain conditions, to request an increase in the senior credit facility of up to $50 million. At December 31, 2010, $55.0 million of the $250.0 million senior revolving credit facility was unused.

On October 13, 2010, we issued $100.0 million in 4.00% Series A Senior Notes. The Series A Senior Notes will mature on October 13, 2021 and are payable in five annual installments of $20.0 million, commencing October 13, 2017. Interest is payable quarterly beginning January 13, 2011. The Series A Senior Notes are unsecured.

Approximate maturities of these obligations are $9.9 million in 2011, $8.2 million in 2012, $6.7 million in 2013, $6.7 million in 2014, $201.6 million in 2015, and $144.0 million thereafter. Some debt agreements require us to maintain certain financial ratios and minimum net worth and contain restrictions on the total amount of debt. We were in compliance with our debt covenants as of December 31, 2010.
