PART I

Item 1. Business

Overview—MSA was founded in Pennsylvania in 1914. We are a global leader in the development, manufacture and supply of safety products that protect people and facility infrastructures. Our safety products typically integrate a 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 a broad range of markets including the oil, gas and petrochemical, fire service, construction, utilities, and mining industries. We also sell products designed for specific industrial and military applications. The company's core products include fixed gas and flame detection systems, breathing apparatus where self-contained breathing apparatus ("SCBA") is the principal product, portable gas detection instruments, industrial head protection products, fire and rescue helmets, and fall protection devices.

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 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 to develop industry specific 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. To best serve these customer preferences, we have organized our business into six geographic operating segments that are aggregated into three reportable geographic segments: Americas, International and Corporate. 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 and much of our business is conducted outside the U.S., currency fluctuations may affect our results of operations and financial position and may affect the comparability of our results between financial periods.

Products—We manufacture and sell a comprehensive line of safety products to protect the safety of workers and facility infrastructures around the world in the oil, gas and petrochemical, fire service, construction, utilities, and mining industries. We also sell products designed for specific industrial and military applications. Our products protect people against a wide variety of hazardous or life-threatening situations.

The following is a brief description of each of our product categories:

Core products. MSA's corporate strategy includes a focus on driving sales of core products, which have leading market positions and a competitive advantage. Core products, as mentioned above, include fixed gas and flame detection systems, breathing apparatus where SCBA is the principal product, portable gas detection instruments, industrial head protection products, fire and rescue helmets, and fall protection devices. These products receive the highest levels of investment and resources as they typically realize a higher gross profit margin and provide higher levels of return on investment than non-core products. Core products comprised approximately 82% of sales in both 2016 and 2015.

The following is a brief description of our core product offerings:

Fixed gas and flame detection instruments ("FGFD"). Our permanently installed fixed gas and flame detection instruments are used in oil, gas and petrochemical facilities and general industrial production facilities to detect the presence or absence of various gases in the air. Typical applications of these instruments include the detection of an oxygen deficiency in confined spaces or the presence of combustible or toxic gases. FGFD product lines have a meaningful portion of overall revenue generated from recurring business including replacement components and related service. A portion of business from this product line is project oriented and more associated with upstream exploration and production activity. We sell these instruments in both our Americas and International segments. Key products include:

• Multi-point permanently installed gas detection systems. This product line is used to 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 petrochemical, pulp and paper, wastewater, refrigerant monitoring, and general industrial applications. These systems utilize a wide array of sensing technologies including electrochemical, catalytic, infrared and ultrasonic.

4

• Flame detectors and open-path infrared gas detectors. These instruments 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 long distances, making them suitable for use in such applications as offshore oil rigs, storage vessels, refineries, pipelines and ventilation ducts. First used in the oil and gas industry, our systems now have broad applications in petrochemical facilities, the transportation industry and in pharmaceutical production.

• The recent acquisition of Senscient, Inc. ("Senscient"), a leader in laser-based gas detection technology strengthens MSA’s leading position in the global market for FGFD systems, represents a key step in the execution of MSA’s Core Product growth strategy and fast tracks MSA’s new product development efforts in the area of laser-based, open-path gas detection. Senscient’s innovative technology provides a strong complement to our existing fixed gas and flame detection portfolio. The technology provides further technical and competitive differentiation to MSA’s fixed gas and flame detection business.

Breathing apparatus products. Breathing apparatus products include SCBA, face masks and respirators, where SCBA is the primary product offering. SCBA are used by first responders, petrochemical plant workers and anyone entering an environment deemed immediately dangerous to life and health. Our newest breathing apparatus product, the MSA G1 SCBA, is an entirely redesigned platform that offers many customizable and differentiated features, including the first and only Integrated Thermal Imaging Camera available on the market. We currently have 6 patents issued and an additional 9 patents pending for the MSA G1 SCBA. Our strongest sales of breathing apparatus products have historically been in North America, across Western Europe and in China.

Portable gas detection instruments. Our hand-held portable gas detection instruments are used to detect the presence or absence of various gases in the air. The product is used by oil, gas and petrochemical workers; general industry workers; miners; first responders or anyone working in a confined space environment. Typical applications of these instruments include the detection of an oxygen deficiency in confined spaces or the presence of combustible or toxic gases. 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 ALTAIR^® 2X Single or Two Gas Detectors; ALTAIR^® 4X and ALTAIR^® 5X Multigas Detectors with XCell^® sensor technology, which include internally developed sensors, provide faster response times and unsurpassed durability in a tough, easy-to-operate package. The ALTAIR^® 2XP provides users with unique and significant cost of ownership advantages over competitive offerings by giving users the ability to perform their own daily bump test to make sure the instrument is functioning properly. We sell these instruments in both our Americas and International segments.

Head protection. We offer a complete line of industrial head protection that includes the iconic V-Gard^® helmet brand, a bellwether product in MSA's portfolio for over 50 years. We offer customers a wide range of color choices and we are a world leader in the application of customized logos. Our industrial head protection has a wide user base including oil, gas and petrochemical workers, steel and construction workers, miners and industrial workers. Our Fas-Trac^® III Suspension system was designed to provide comfort for the users of our helmets without sacrificing safety. Our strongest sales of head protection products have historically been in North America and Brazil.

Fire and rescue helmets. We offer a complete line of fire helmets that includes our Cairns^® and Gallet^® helmet brands. Our Cairns helmets are primarily used by firefighters in North America while the Gallet helmets are used by firefighters across our International segment. Rescue helmets including the F2 X-Trem Brand, are used by military and first responders outside of North America. We sell these products in both our Americas and International segments.

Fall protection. Our broad line of fall protection equipment includes confined space equipment, harnesses, fall arrest equipment, lanyards and lifelines. Fall protection equipment is used by workers in the construction industry, oil, gas and petrochemical market, utilities industry, aerospace industry, and general industrial applications, and anyone working at height. In October 2015, MSA acquired UK-based Latchways plc ("Latchways"). This acquisition - complementary from a product, geographic and end market standpoint - doubled our fall protection revenue, positioning MSA as one of the largest fall protection providers globally.

Non-core products. MSA maintains a portfolio of non-core products which includes both adjacent and peripheral offerings. Adjacent products reinforce and extend the core, drawing upon our customer relationships, distribution channels, geographical presence and technical experience. These products are complementary to the core offerings and have their roots within the core product value chain. Key adjacent products include respirators, eye and face protection, thermal imaging cameras, ballistic helmets, and gas masks. Gas masks and ballistic helmet sales are the primary purchases from our military customers and were approximately $55 million globally in 2016 compared to $56 million in 2015. Peripheral products are primarily sold to the mining industry and reflect a small portion of consolidated sales.

Customers—Our customers generally fall into two categories: distributors and industrial or military end-users. In our Americas segment, the majority of our sales are made to our distributors. In our International segment, sales are made through both indirect and direct sales channels. For the year ended December 31, 2016, no individual customer represented more than 10% of our sales.

Sales and Distribution—Our sales and distribution team consists of marketing, field sales and customer service organizations. In most geographic areas, our field sales organizations work jointly with select distributors to call on end-users and educate them about hazards, exposure limits, safety requirements and product applications, as well as the specific performance attributes of our products. In our South Africa and Eastern Europe regions, where distributors are not as well established, our sales associates often work with and sell directly to end-users. We believe that understanding end-user requirements is critical to increasing MSA's market share.

The in-depth customer training and education provided by our sales associates to our customers is critical to ensuring proper use of many of our products, such as SCBA 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 in product application, industry standards and regulations.

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 authorized national, regional and local distributors. Some of our key distributors include W.W. Grainger Inc., Airgas, Sonepar, Bunzl and Fastenal. 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 International segment, 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. No individual distributor accounts for more than 10% of our sales.

Competition— The global safety products market is broad and highly fragmented with few participants offering a comprehensive line of safety products. The sophisticated safety products market in which we compete is comprised of both core and non-core offerings and is a subset of the larger personal protection equipment market. We maintain leading positions in nearly all of our core products. Over the long-term, we believe global demand for safety products will continue to grow. Purchases of these products are non-discretionary, protecting workers' health in hazardous and life-threatening work environments. Their use is often mandated by government and industry regulations, which are increasingly enforced on a global basis.

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 several 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, technology, agency approvals, design and style), brand name recognition, service support and price.

We believe we compete favorably within each of our operating segments as a result of our high quality, our innovative offerings and strong brand trust and recognition.

Research and Development—To achieve and maintain our market leading positions, we operate several sophisticated research and development facilities. We believe our dedication and commitment to innovation and research and development allows us to produce state-of-the-art safety products that are often first to market and exceed industry standards. In 2016, 2015 and 2014, on a global basis, we spent $46.8 million, $48.6 million and $48.2 million, respectively, on research and development, reflecting 4.1%, 4.3% and 4.3% of sales respectively. Our primary engineering groups are located in the United States, Germany, China and 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 customers' needs and available technology, as well as the 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 operating segments.

6

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. These organizations include the National Institute for Occupational Safety and Health ("NIOSH"), the National Fire Protection Association ("NFPA"), American National Standards Institute ("ANSI"), International Safety Equipment Association ("ISEA"), and their overseas counterparts. We work with these organizations to develop industry specific product requirements and standards and anticipate their impact on our product lines. Key members of our management team understand the impact that these standard-setting organizations have on our new product development pipeline. As such, management devotes significant time and attention to anticipating a new standard’s impact on our sales and operating results. Because of our understanding of customer needs, membership on global standard-setting bodies, investment in research and development and our unique new product development process, we believe we are well-positioned to anticipate and adapt to changing product standards. While we acknowledge that the length of the approval process can be unpredictable, we also believe that we are well positioned to gain the approvals and certifications necessary to meet new government and multinational product regulations.

Patents and Intellectual Property—We own 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, which comprise approximately two thirds of our cost of sales. 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, high density polyethylene, 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, thus far we have not experienced any significant problems in obtaining adequate raw materials. Please refer to MSA's Form SD filed on May 31, 2016 for further information on our conflict minerals analysis. Form SD may be obtained free of charge at www.sec.gov.

Associates—At December 31, 2016, we employed approximately 4,300 associates of which 2,000 were employed by our International segment. 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 significant work stoppage in over 10 years and believe our relations with our associates are strong.

Environmental Matters— Our facilities and operations are subject to laws and regulations relating to environmental protection and human health and safety. In the opinion of management, compliance with current environmental protection laws will not have a material adverse effect on our financial condition. See Item 1A, Risk Factors, for further information regarding our environmental risks which could impact the Company.

Seasonality— Our operating results are not significantly affected by seasonal factors. Sales are generally higher during the second and fourth quarters. During periods of economic expansion or contraction and following significant catastrophes, our sales by quarter have varied from this seasonal pattern. Government related sales tend to spike in the fourth quarter. Americas sales tend to be strong during the oil and gas market turnaround seasons late in the first quarter, early in the second quarter and then again at the end of the third quarter and beginning of the fourth quarter. International segment sales are typically weaker for the Europe region in the summer holiday months of July and August and seasonality can be strongly affected by the timing of delivery of larger orders. Invoicing and the delivery of larger orders can affect sales patterns variably across all reporting segments.

Item 1A. Risk Factors

We may experience losses from cumulative trauma product liability claims. The inability to collect insurance receivables and the transition to becoming largely self-insured for cumulative trauma product liability claims, could have a materially adverse effect on our business, operating results, financial condition and liquidity.

Our subsidiary, Mine Safety Appliances Company, LLC (“MSA LLC”) is presently named as a defendant in 1,794 cumulative trauma lawsuits comprised of 3,023 claims. 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, mesothelioma, or coal worker’s pneumoconiosis. The products at issue were manufactured many years ago and are not currently offered by MSA LLC. Although we have reserved against the portion of claims outstanding, the reserve does not take into account all the currently pending coal dust claims against MSA LLC or any incurred but not reported (“IBNR”) claims, which losses could have a materially adverse effect on our business, operating results, financial condition and liquidity. Because litigation is subject to inherent uncertainties, and unfavorable rulings or developments could occur, there can be no certainty that MSA LLC may not ultimately incur charges in excess of presently recorded liabilities with respect to claims included within the existing reserve or related to claims not included in the reserve. We will adjust the reserve for our liability relating to cumulative trauma claims from time to time based on the maturation of claims, developing facts and circumstances, and if actual experience is worse than previously projected. These adjustments may reflect changes in estimates for claims currently covered by the reserve, as well as estimated liabilities for claims not presently covered by the reserve and IBNR claims, in the event we become able to reasonably assess the probability and estimate the magnitude of potential losses. These adjustments may be material and could increase the year over year variability of our financial results.

In the normal course of business, MSA LLC, makes payments to settle these types of cumulative trauma product liability claims and for related defense costs, and records receivables for the amounts believed to be recoverable under insurance. MSA LLC has recorded insurance receivables totaling $159.9 million at December 31, 2016. As described in greater detail in Note 19 of the Consolidated Financial Statements in Part II Item 8 of this Form 10-K, MSA LLC is currently involved in insurance coverage litigation regarding the rights and obligations under numerous insurance policies, and for the payment of amounts recorded as insurance receivables. Various factors could affect the timing and amount of recovery of insurance receivables, including: the outcome of coverage litigation, the outcome of negotiations with insurers, and the extent to which insurers may become insolvent in the future. Failure to recover amounts due from MSA LLC’s insurance carriers would result in it being unable to recover amounts already paid to resolve claims (and recorded as insurance receivables) and could have a materially adverse effect on our business, consolidated operating results, financial condition and liquidity.

We have determined that at some point in the next 18 months, even if insurance coverage litigation is generally successful, MSA LLC will become largely self-insured for costs associated with cumulative trauma product liability claims and most of the related costs will be expensed without the expectation such costs will be covered by insurance reimbursement. The exact point when this transition will happen is difficult to predict and subject to a number of variables, including the pace at which future cumulative trauma product liability costs are incurred and the results of litigation and negotiations with insurance carriers. After it becomes largely self-insured, MSA LLC may still obtain some insurance reimbursement from negotiated coverage-in-place agreements (although that coverage may not be immediately triggered or accessible) or from other sources of coverage.  However, the precise amount of insurance reimbursement that may be available cannot be determined with specificity at this time.

MSA LLC may experience an increase in newly filed claims or more aggressive settlement demands from plaintiffs at any time, which could accelerate the point at which MSA LLC becomes self-insured. We expect that once we become largely self-insured for cumulative trauma claims, we could experience greater year over year variability in our consolidated financial results.

8

On February 26, 2016, a Kentucky state court jury in the James Couch claim rendered a verdict against MSA LLC (the "Couch verdict") of $7.2 million dollars (comprised of $3.2 million of an apportioned share of compensatory damages and $4.0 million in punitive damages). The Couch claim is a cumulative trauma product liability lawsuit involving exposure to coal dust. MSA LLC is appealing the Couch verdict. MSA LLC experienced an increase in coal dust related claims filed in 2016. Such claims could result in increased product liability expense in the future, and the impact of such an increase in claims to our results of operations may be worsened to the extent MSA LLC is self-insured. Please refer to Note 19 Contingencies of the Consolidated Financial Statements in Part II Item 8 of this Form 10-K for further details on the Couch verdict.

Claims of injuries from our products, product defects or recalls of our products could have a materially adverse effect on our business, operating results, financial condition and liquidity.

MSA and its subsidiaries 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. In the event the parties using our products are injured or any of our products prove to be defective, we could be subject to claims with respect to such injuries. In addition, we may be required to or may voluntarily recall or redesign certain products that could potentially be harmful to end users. Any claim or product recall that results in significant expense or adverse publicity against us could have a materially adverse effect on our business, consolidated operating results, financial condition and liquidity, including any successful claim brought against us in excess or outside of available insurance coverage.

Unfavorable economic and market conditions could materially and adversely affect our business, results of operations and financial condition.

We are subject to risks arising from adverse changes in global economic conditions. The global economy remains unstable. For example, we are currently seeing a slowdown in China, recessionary conditions in Brazil and a slowdown in certain regions that are dependent upon the mining of certain commodities. We expect economic conditions will continue to be challenging and uneven for the foreseeable future. Adverse changes in economic conditions could result in 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.

A portion of MSA's sales are made to customers in the oil, gas and petrochemical market. These sales expose MSA to the risks of doing business in that global market. We estimate that between 25% - 30% of our global business is sold into the energy market vertical with the most significant exposure in industrial head protection, portable gas detection and FGFD. Approximately 10% - 15% of consolidated revenue, primarily in industrial head protection and portable gas detection, is more exposed to a pull back in employment trends across the energy market. Another 5% - 10% of consolidated revenue, primarily in the FGFD product line is more exposed to a pull back in capital equipment spending within the energy market. It is possible that the volatility in upstream, midstream and downstream markets, driven partly by geopolitical factors, could negatively impact our business and our results of operations and financial condition.

A reduction in the spending patterns of government agencies or delays in obtaining government approval for our products 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 other government agencies is, in large part, driven by available government funding. Government budgets are set annually and we cannot assure 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.

Our ability to market and sell our products is subject to existing government 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 safety of people and infrastructures 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 re-engineer 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 can cause customers to accelerate or delay buying decisions.

9

We are subject to various federal, state and local laws and any violation of these laws could adversely affect our results of operations.

We are subject to extensive regulation from U.S. federal, state, and local governments, as well as the governments of the countries in which we conduct business. Failure to comply with these regulations could result in severe civil or criminal penalties, sanctions or significant changes to our operations. These actions could have a materially adverse effect on our business, results of operations and financial condition.

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

Included in the extensive laws, regulations and ordinances, to which we are subject, are those relating to the protection of the environment. Examples include 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. Such laws continue to change, 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.

We benefit from free trade laws and regulations, such as the North American Free Trade Agreement and any changes to these laws and regulations could adversely affect our results of operations.

Existing free trade laws and regulations, such as the North American Free Trade Agreement, provide certain beneficial duties and tariffs for qualifying imports and exports, subject to compliance with the applicable classification and other requirements. Changes in laws or policies governing the terms of foreign trade, and in particular increased trade restrictions, tariffs or taxes on imports from countries where we manufacture products, such as China and Mexico, could have a material adverse effect on our business and financial results.

We are subject to various U.S and foreign tax laws and any changes in these laws related to the taxation of businesses could adversely affect our results of operations.

The U.S. Congress, the Organization for Economic Co-operation and Development (or, OECD) and other government agencies in jurisdictions in which we and our affiliates invest or do business have maintained a focus on issues related to the taxation of multinational companies. The OECD has changed numerous long-standing tax principles through its base erosion and profit shifting (“BEPS”) project. Additionally, the Trump administration has announced other proposals for potential reform to the U.S. federal income tax rules for businesses, including reducing the deductibility of interest for corporations, reducing the top marginal rate on corporations and implementing border-adjusted taxation. These proposals for reform, if enacted by the U.S. could adversely impact our effective tax rate.

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.

10

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. We continue to invest significant resources in research and development and market research. However, continued product development and marketing efforts are subject to the risks inherent in the development process. These risks include delays, the failure of new products and product line extensions to achieve anticipated levels of market acceptance and the risk of failed product introductions.

Damage to the reputation of MSA or to one or more of our product brands could adversely affect our business.

Developing and maintaining our reputation, as well as the reputation of our brands, is a critical factor in our relationship with customers, distributors and others. Our inability to address adverse publicity or other issues, including concerns about product safety or quality, real or perceived, could negatively impact our business which could have a materially adverse effect on our business, operating results and financial condition.

A failure of our information systems could materially and adversely affect our business, results of operations and financial condition.

The proper functioning and security of our information systems is critical to the operation of our business. Our information systems may be vulnerable to damage or disruption from natural or man-made disasters, computer viruses, power losses or other system or network failures. In addition, hackers and cybercriminals could attempt to gain unauthorized access to our information systems with the intent of harming our company or obtaining sensitive information such as intellectual property, trade secrets, financial and business development information, and customer and vendor related information. If our information systems or security fail, our business, results of operations and financial condition could be materially and adversely affected.

Like many companies, from time to time, we have experienced attacks on our computer systems by unauthorized outside parties; however, we do not believe that such attacks have resulted in any material damage to us or our customers. Because the techniques used by computer hackers and others to access or sabotage networks constantly evolve and generally are not recognized until launched against a target, we may be unable to anticipate, prevent or detect these attacks. As a result, our technologies and processes may be misappropriated and the impact of any future incident cannot be predicted. Any loss of such information could harm our competitive position, or cause us to incur significant costs to remedy the damages caused by the incident. We routinely implement improvements to our network security safeguards as well as cybersecurity initiatives. We expect to devote increasing resources to the security of our information technology systems. We cannot assure that such system improvements will be sufficient to prevent or limit the damage from any future cyber-attack or network disruptions.

Our plans to continue to improve productivity and reduce complexity may not be successful, which could adversely affect our ability to compete.

MSA has transitioned parts of its European operating segment to a principal operating company ("European reorganization"). This principal operating company model integrates our historically individually managed entities, into one that is a centrally managed organization. We have begun to and plan to continue to leverage the benefits of scale created from this approach and are in the process of implementing a more efficient and cost-effective enterprise resource planning system in additional locations across the International Segment. MSA runs the risk that these and similar initiatives may not be completed substantially as planned, may be more costly to implement than expected, or may not have the positive effects anticipated. In addition, these various initiatives require MSA to implement a significant amount of organizational change which could divert management’s attention from other concerns, and if not properly managed, could cause disruptions in our day-to-day operations and have a negative impact on MSA's financial results. It is also possible that other major productivity and streamlining programs may be required in the future.

11

Our plans to improve future profitability through restructuring programs may not be successful and may lead to unintended consequences.

MSA incurred a significant amount of restructuring expense during 2015, primarily related to headcount reduction. In 2016, certain employees in the Americas segment were offered a voluntary retirement incentive package (“VRIP”). Non-cash special termination benefit expense of approximately $11.5 million is expected to be recorded in the first quarter of 2017 related to these elections. These efforts should contribute to profitability in future periods. Our success will depend on our ability to maintain increased productivity without backfilling certain positions.

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

We have business operations in over 40 foreign countries. In 2016, approximately half 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:

• unexpected changes in regulatory requirements;

• changes in trade policy or tariff regulations;

• changes in tax laws and regulations;

• changes to the company's legal structure could have unintended tax consequences;

• inability to generate sufficient profit in certain foreign jurisdictions could lead to additional valuation allowances on deferred tax assets;

• 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 embargoes;

• nationalization and expropriation;

• increased international instability or potential instability of foreign governments;

• effectiveness of worldwide compliance with MSA's anti-bribery policy, local laws and the Foreign Corrupt Practices Act

• the ability to effectively negotiate with labor unions in foreign countries;

• 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 the risk that purchased components and materials are unavailable or available at excessive cost due to material shortages, excessive demand, currency fluctuation 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 or otherwise disrupted. 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.

12

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, 2016, our operations outside of the United States accounted for approximately half of our net sales. The results of our foreign operations are generally 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 consolidated financial statements are stated in U.S. dollars, such fluctuations may affect our consolidated 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 consolidated 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.

Our inability to successfully identify, consummate and integrate current and 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. On October 21, 2015, MSA completed the acquisition of Latchways - a leading global provider of innovative fall protection systems and solutions based in the United Kingdom (UK). Additionally on September 19, 2016, MSA completed the acquisition of Senscient, which is also headquartered in the UK and is a leader in laser-based gas detection technology. Please refer to Note 13 in Part II Item 8 of this Form 10-K for further details. 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 including Latchways and Senscient, 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 consolidated 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.

13

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.

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 consolidated results of operations and financial condition could be materially and adversely affected.

We may be required to recognize impairment charges for our long-lived assets or available for sale investments.

At December 31, 2016, the net carrying value of long-lived assets (property, plant and equipment, goodwill and other intangible assets) totaled approximately $559.0 million. In accordance with generally accepted accounting principles, we periodically assess these assets to determine if they are impaired. Significant negative industry or economic trends, disruptions to our business, unexpected significant changes or planned changes in use of the assets and divestitures may result in impairments to goodwill and other long-lived assets. Future impairment charges could significantly affect our consolidated results of operations in the periods recognized. Impairment charges would also reduce our consolidated shareholders’ equity and increase our debt-to-total-capitalization ratio, which could negatively impact our credit rating and access to debt and equity markets.

Risks related to our defined benefit pension and other post-retirement plans may adversely impact our results of operations and cash flow.

Significant changes in actual investment return on pension assets, discount rates, and other factors could adversely affect our results of operations and pension contributions in future periods. U.S. generally accepted accounting principles require that we calculate income or expense for the plans using actuarial valuations. These valuations reflect assumptions about financial markets and interest rates, which may change based on economic conditions. Funding requirements for our pension plans may become more significant. However, the ultimate amounts to be contributed are dependent upon, among other things, interest rates, underlying asset returns and the impact of legislative or regulatory changes related to pension funding obligations. For further information regarding our pension plans, refer to "Pensions and Other Post-retirement Benefits" in Note 14 of Item 8 Financial Statements and Supplementary Data.

If we fail to meet our debt service requirements or the restrictive covenants in our debt agreements or if interest rates increase, our results of operations and financial condition could be materially and adversely affected.

We have a substantial amount of debt upon which we are required to make scheduled interest and principal payments and we may incur additional debt in the future. A significant portion of our debt bears interest at variable rates that may increase in the future. Our debt agreements require us to comply with certain restrictive covenants. If we are unable to generate sufficient cash to service our debt or if interest rates increase, our consolidated results of operations and financial condition could be materially and adversely affected. Additionally, a failure to comply with the restrictive covenants contained in our debt agreements could result in a default, which if not waived by our lenders, could substantially increase borrowing costs and require accelerated repayment of our debt. Please refer to Note 11 of the Consolidated Financial Statements in Part II Item 8 of this Form 10-K for commentary on our compliance with the restrictive covenants in our debt agreements as of December 31, 2016.

Comparison of Five-Year Cumulative Total Return

The following paragraph compares the most recent five year performance of MSA stock with (1) the Standard & Poor’s 500 Composite Index and (2) the Russell 2000 Index. Because our competitors are principally privately held concerns or subsidiaries or divisions of corporations engaged in multiple lines of business, we do not believe it feasible to construct a peer group comparison on an industry or line-of-business basis. The Russell 2000 Index, while including corporations both larger and smaller than MSA in terms of market capitalization, is composed of corporations with an average market capitalization similar to us.

COMPARISON OF 5 YEAR CUMULATIVE TOTAL RETURN

Among MSA Safety Incorporated, the S&P 500 Index, and the Russell 2000 Index

Assumes $100 invested on December 31, 2011 in stock or index, including reinvestment of dividends. Fiscal year ending December 31.

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.”

On October 21, 2015, the Company acquired 100% of the common stock of Latchways plc ("Latchways") for $190.9 million in cash. Latchways, which is headquartered in the United Kingdom, is a leading provider of innovative fall protection systems and solutions. The acquisition of Latchways represents a key step in the execution of our corporate strategy by expanding our investment in one of the largest and fastest growing product segments of the global safety market. This acquisition will double our fall protection business, positioning MSA as one of the largest fall protection providers globally. Within the fall protection space, the Latchways acquisition strengthens our position in permanent engineered systems and our presence in other sectors such as utilities, telecommunications, and aircraft maintenance. The data presented in Part II Item 6 of this Form 10-K should be read in conjunction with the following comments.

The Americas and International reportable segments were established on January 1, 2016. The Americas segment is comprised of our operations in North America and Latin America geographies. The International segment is comprised of our operations of all geographies outside of the Americas. Certain global expenses are now allocated to each segment in a manner consistent with where the benefits from the expenses are derived. The 2015 and 2014 segment results have been recast to conform with current period presentation. Please refer to Note 7 Segment Information, which is included in Part II Item 8 of this Form 10-K, for further information.

MSA's South African personal protective equipment distribution business and MSA's Zambian operations had historically been part of the International reportable segment. On February 29, 2016, the Company sold 100% of the stock associated with these operations. In accordance with generally accepted accounting principles, these operations and related results are excluded from continuing operations and are presented as discontinued operations in all periods presented. Please refer to Note 20 Discontinued Operations, which is included in Part II Item 8 of this Form 10-K, for further commentary on these discontinued operations.

On September 19, 2016, the Company acquired 100% of the common stock of Senscient, Inc. for $19.1 million in cash. Senscient, which is headquartered in the UK, is a leader in laser-based gas detection technology. The acquisition of Senscient expands and enhances MSA’s technology offerings in the global market for fixed gas and flame detection systems, as the Company continues to execute its core product growth strategy.

BUSINESS OVERVIEW

We are a global leader in the development, manufacture and supply of safety products that protect people and facility infrastructures.  Many MSA products integrate a combination of electronics, mechanical systems and advanced materials to protect users against hazardous or life-threatening situations.  The company's comprehensive product line is used by workers around the world in a broad range of markets, including the oil, gas and petrochemical, fire service, construction, utilities, and mining industries.  MSA's core products include fixed gas and flame detection systems, breathing apparatus where SCBA is the principal product, portable gas detection instruments, industrial head protection products, fire and rescue helmets, and fall protection devices.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.

We tailor our product offerings and distribution strategy to satisfy distinct customer preferences that vary across geographic regions. To best serve these customer preferences, we have organized our business into six geographical operating segments that are aggregated into three reportable geographic segments: Americas, International and Corporate. Each segment includes a number of operating segments. In 2016, 59% and 41% of our net sales were made by our Americas and International segments, respectively.

Americas. Our largest manufacturing and research and development facilities are located in the United States. We serve our markets across the Americas with manufacturing facilities in the U.S., Mexico, Brazil and Canada. Operations in other Americas segment countries focus primarily on sales and distribution in their respective home country markets.

International. Our International segment includes companies in Europe, Middle East, Africa, and the Asia Pacific region, some of which are in developing regions of the world. In our largest International affiliates (in Germany, France, United Kingdom, Ireland and China), we develop, manufacture and sell a wide variety of products. In China, the products manufactured are sold primarily in the home country as well as regional markets. Operations in other International segment countries focus primarily on sales and distribution in their respective home country markets. Although some of these companies may perform limited production, most of their sales are of products manufactured in our plants in Germany, France, the U.S., United Kingdom, Ireland, Sweden and China or are purchased from third party vendors.

Corporate. The Corporate segment primarily consists of general and administrative expenses incurred in our corporate headquarters, costs associated with corporate development initiatives, legal expense, interest expense, foreign exchange gains or losses, and other centrally-managed costs. Corporate general and administrative costs comprise the majority of the expense in the Corporate segment. During the year ended December 31, 2016, corporate general and administrative costs were $38.9 million, which included $2.5 million of strategic transaction costs related to mergers and acquisitions.During the year ended December 31, 2015, corporate general and administrative costs were $38.3 million, which included $7.5 million of strategic transaction costs related to the Latchways acquisition. During the year ended December 31, 2014, corporate general and administrative costs were $37.4 million.

RESULTS OF OPERATIONS

Year Ended December 31, 2016 Compared to Year Ended December 31, 2015

Net Sales	2016	2015	Dollar Increase (Decrease)	Percent Increase (Decrease)
(In millions)
Consolidated Continuing Operations	$1,149.5	$1,130.8	$18.7	1.7%
Americas	678.4	704.8	(26.4)	(3.7)%
International	471.1	426.0	45.1	10.6%

Net Sales from continuing operations. Net sales for the year ended December 31, 2016 were $1,149.5 million, an increase of $18.7 million, from $1,130.8 million for the year ended December 31, 2015. Organic constant currency sales decreased by 1% for the year ended December 31, 2016. Please refer to the Net Sales from Continuing Operations table below for a reconciliation of the year over year sales change.

21

Net Sales from Continuing Operations	Year Ended December 31, 2016 versus December 31, 2015
(Percent Change)	Americas	International	Consolidated Continuing Operations
GAAP reported sales change	(3.7)%	10.6%	1.7%
Currency translation effects	(1.9)%	(2.4)%	(2.1)%
Constant currency sales change	(1.8)%	13.0%	3.8%
Acquisitions	1.3%	10.3%	4.8%
Organic constant currency change	(3.1)%	2.7%	(1.0)%

Note: Organic constant currency sales change is a non-GAAP financial measure provided by the Company to give a better understanding of the Company's underlying business performance. Organic constant currency sales change is calculated by removing the percentage impact from acquisitions and currency translation effects from the overall percentage change in net sales.

Net sales for the Americas segment were $678.4 million for the year ended December 31, 2016, a decrease of $26.4 million, or 4% compared to $704.8 million for the year ended December 31, 2015. Currency translation effects decreased Americas segment sales by 2%, reflecting weaker currencies across Latin America. Acquisitions, primarily Latchways, increased sales in the Americas segment by 1%. In 2016, organic constant currency sales in the Americas segment decreased 3% compared to the prior year. This decrease was primarily related to a lower level of shipments of the G1 self-contained breathing apparatus ("SCBA"). Our sales in 2015 benefited from a higher backlog at December 31, 2014 of approximately $35 million. We shipped these additional units in 2015 and had a more normalized backlog to start 2016. Furthermore, industrial head protection sales decreased, there was a lower level of fixed gas and flame detection sales stemming from reduced project spending in the energy market, and sales of other non-core products decreased. These declines were partially offset by an improvement in portable gas detection as well as fire and rescue helmet sales.

Net sales for the International segment were $471.1 million for the year ended December 31, 2016, an increase of $45.1 million, or 11%, compared to $426.0 million for the year ended December 31, 2015. Currency translation effects decreased International segment net sales by 2%, reflecting a weaker British pound and euro. Acquisitions, primarily Latchways, increased sales in the International segment by 10%. Organic constant currency sales in the International segment increased 3% in 2016, driven by growth in breathing apparatus in both developed and emerging markets, fixed gas and flame detection projects in the Middle East, and portable gas detection in Europe. These increases were partially offset by a decline in fire and rescue helmet sales and other non-core product sales.

Gross profit. Gross profit for the year ended December 31, 2016 was $523.6 million, an increase of $22.5 million, or 4%, compared to $501.1 million for the year ended December 31, 2015. The ratio of gross profit to net sales was 45.6% in 2016 compared to 44.3% in 2015. The higher gross profit ratio during 2016 is primarily attributable to improved margins on our G1 SCBA associated with our value engineering initiatives and improvements in our warranty expense and inventory and obsolescence expense.

Selling, general and administrative expenses. Selling, general and administrative expenses were $306.1 million for the year ended December 31, 2016, a decrease of $9.2 million, compared to $315.3 million for the year ended December 31, 2015. Selling, general and administrative expenses were 26.6% of net sales in 2016, compared to 27.9% of net sales in 2015. Organic constant currency selling, general, and administrative expense decreased 3% during 2016 driven by headcount reductions and implementation of discretionary spending controls related to our global cost reduction program. The following table presents a reconciliation of the year over year expense change for selling, general, and administrative expenses.

22

Selling, general, and administrative expenses	Year Ended December 31, 2016 versus December 31, 2015
(Percent Change)	Consolidated Continuing Operations
GAAP reported change	(2.9)%
Currency translation effects	(2.2)%
Constant currency change	(0.7)%
Acquisitions and related strategic transaction costs	2.4%
Organic constant currency change	(3.1)%

Note: Organic constant currency change is a non-GAAP financial measure provided by the Company to give a better understanding of the Company's underlying business performance. Organic constant currency change in selling, general, and administrative expenses is calculated by removing the percentage impact from acquisitions and currency translation effects from the overall percentage change in GAAP selling, general, and administrative expense. Management believes excluding acquisitions and currency translation effects provide investors with a greater level of clarity into spending levels on a year-over-year basis.

Research and development expenses. Research and development expense was $46.8 million for the year ended December 31, 2016, a decrease of $1.8 million, or 3.7%, compared to $48.6 million for the year ended December 31, 2015. Research and development expense was 4.1% of net sales in 2016, compared to 4.3% of net sales in 2015 and we expect research and development expense to range from 4.0% to 4.5% of sales for the year ending December 31, 2017 as we continue to develop new products for global safety markets.

Restructuring and other charges. During the year ended December 31, 2016, the Company recorded restructuring charges, net of adjustments, of $5.7 million, primarily related to severance costs for staff reductions associated with ongoing initiatives to right size our operations in Europe, Brazil, and Japan. This compared to charges of $12.3 million during the year ended December 31, 2015, primarily related to severance costs associated with our global cost reduction program.

In September 2016, certain employees in the Americas segment were offered a voluntary retirement incentive package (“VRIP”). The election window for participation closed on October 17, 2016. The employees were required to render service through January 31, 2017 to receive the VRIP and had until February 6, 2017 to revoke their election. None of the 83 employees who accepted the VRIP revoked their election to retire under the terms of the plan. Non-cash special termination benefit expense of approximately $11.5 million is expected to be recorded in the first quarter of 2017 related to these elections. All benefits will be paid from our over funded North America pension plan. Including our non-cash special termination benefit expense and additional initiatives across our International segment, we expect to incur between $13 million and $15 million in restructuring expense over the next several quarters as we continue to evaluate additional restructuring activities, and anticipate savings in 2017 of approximately $10.0 million related to these programs.

Currency exchange. Currency exchange losses were $0.8 million during the year ended December 31, 2016, compared to $2.2 million during the year ended December 31, 2015. Currency exchange losses in both years were mostly unrealized and related primarily to the effect of the strengthening U.S. dollar on intercompany balances. Refer to Note 17 to the Consolidated Financial Statements in Part II Item 8 of this Form 10-K, for information regarding our currency exchange rate risk management strategy.

GAAP operating income. Consolidated operating income for the year ended December 31, 2016 was $164.2 million, an increase of $41.5 million, or 34%, compared to $122.7 million for the year ended December 31, 2015. Improved operating income for 2016 was driven by higher gross profit margins associated with our value engineering initiatives; lower selling, general and administrative costs stemming from our cost reduction programs; lower restructuring costs and lower currency exchange losses.

Adjusted operating income. Americas adjusted operating income for the year ended December 31, 2016 was $162.8 million, an increase of $20.8 million, or 15%, compared to $142.0 million for the year ended December 31, 2015. Improved margins for our G1 SCBA associated with our value engineering initiatives and lower selling, general and administrative expense stemming from our cost reduction programs contributed to adjusted operating income growth during 2016.

International adjusted operating income for the year ended December 31, 2016 was $46.5 million, an increase of $13.0 million, or 39%, compared to $33.5 million for the year ended December 31, 2015. Increased revenues from the acquisition of Latchways combined with organic growth in both developed and emerging international markets contributed to improved adjusted operating income as compared to 2015. Lower selling, general and administrative expense as a result of our global cost reduction program also contributed to improvements in operating income.

23

Corporate segment adjusted operating loss for the year ended December 31, 2016 was $38.6 million, an increase of $0.3 million, or 1%, compared to an operating loss of $38.3 million for the year ended December 31, 2015, reflecting higher stock compensation, bonus, and legal expenses.

The following table provides a reconciliation from GAAP operating income to adjusted operating income. Adjusted operating margin % is calculated as adjusted operating income divided by net sales.

Adjusted operating income	Year Ended December 31, 2016
(In thousands)	Americas	International	Corporate	Consolidated Continuing Operations
Net sales	$678,433	$471,097	$—	$1,149,530
GAAP operating income				164,192
Restructuring and other charges				5,694
Currency exchange losses, net				766
Adjusted operating income	$162,788	$46,491	$(38,627)	$170,652
Adjusted operating margin %	24.0%	9.9%

Note: Adjusted operating income is a non-GAAP financial measure used by the chief operating decision maker to evaluate segment performance and allocate resources. Adjusted operating income is reconciled above to the nearest GAAP financial measure, Operating income.

Total other expense, net. Other expense for the year ended December 31, 2016 was $12.3 million, an increase of $0.6 million, or 5%, compared to $11.7 million for the year ended December 31, 2015. The increase reflects higher interest expense associated with the Latchways and Senscient acquisitions.

Income taxes. The effective tax rate for the year ended December 31, 2016 was 38.1%, compared to 40.0% for the year ended December 31, 2015. The decrease was primarily due to less exit taxes partially offset by higher U.S. profitability. The effective tax rate for the year is inclusive of exit taxes related to our European reorganization of 4.3% compared to 6.9% for the same period last year.

MSA finalized its European reorganization during 2016. The reorganization is designed to drive optimal performance by aligning certain strategic planning and decision making into a single location enabled by a common IT platform. During 2016, the Company incurred $6.5 million of charges associated with exit taxes related to our European reorganization compared to $7.7 million in 2015.

Net income from continuing operations attributable to MSA Safety Incorporated. Net income from continuing operations was $92.7 million for the year ended December 31, 2016, or $2.44 per diluted share, an increase of $23.1 million, or 33%, compared to $69.6 million, or $1.84 per diluted share, for the year ended December 31, 2015 as a result of the factors described above.

Net (loss) income from discontinued operations attributable to MSA Safety Incorporated. Net loss from discontinued operations was $0.8 million for the year ended December 31, 2016, or $0.02 per diluted share compared to net income of $1.2 million, or $0.03 per diluted share, for the year ended December 31, 2015. Please refer to Note 20 to the Consolidated Financial Statements in Part II Item 8 of this Form 10-K.

Year Ended December 31, 2015 Compared to Year Ended December 31, 2014

Net Sales from continuing operations. Net sales for the year ended December 31, 2015 were $1,130.8 million, a decrease of $3.1 million, from $1,133.9 million for the year ended December 31, 2014. Organic constant currency sales increased by 7% for the year ended December 31, 2015. Please refer to the Net Sales from Continuing Operations table below for a reconciliation of the year over year sales change.

Net Sales	2015	2014	Dollar Increase (Decrease)	Percent Increase (Decrease)
(In millions)
Consolidated Continuing Operations	$1,130.8	$1,133.9	$(3.1)	(0.3)%
Americas	704.8	663.7	41.1	6.2%
International	426.0	470.2	(44.2)	(9.4)%

Net Sales from Continuing Operations	Year Ended December 31, 2015 versus December 31, 2014
(Percent Change)	Americas	International	Consolidated Continuing Operations
GAAP reported sales change	6.2%	(9.4)%	(0.3)%
Currency translation effects	(4.3)%	(12.8)%	(7.8)%
Constant currency sales change	10.5%	3.4%	7.5%
Acquisitions	0.2%	1.9%	0.9%
Organic constant currency change	10.3%	1.5%	6.6%

Note: Organic constant currency sales change is a non-GAAP financial measure provided by the Company to give a better understanding of the Company's underlying business performance. Organic constant currency sales change is calculated by removing the percentage impact from acquisitions and currency translation effects from the overall percentage change in net sales.

Net sales for the Americas segment were $704.8 million for the year ended December 31, 2015, an increase of $41.1 million million, or 6%, compared to $663.7 million for the year ended December 31, 2014. Currency translation effects decreased Americas segment sales by 4%, reflecting weaker currencies in Latin America. In 2015, organic constant currency sales in the Americas segment increased 10% over the prior year on strong G1 self-contained breathing apparatus ("SCBA") sales across the segment. Strength in the fire service market was partially offset by decreased demand in the gas, petroleum, & chemical markets, reflecting decreased shipments of portable gas detection, industrial head protection, and fixed gas and flame detection.

Net sales for the International segment were $426.0 million for the year ended December 31, 2015, an decrease of $44.2 million, or 9%, compared to $470.2 million for the year ended December 31, 2014. Currency translation effects decreased International segment net sales by 13%, reflecting weakened currencies across several International geographies, notably in Europe and Australia. Organic constant currency sales in the International segment provided 2% growth in 2015, driven by increased shipments of industrial head protection, portable gas detection, and fixed gas and flame detection in the Middle East and Europe, and higher fire helmets sales in Pacific Asia.

Gross profit. Gross profit for the year ended December 31, 2015 was $501.1 million, a decrease of $14.2 million, or 3%, from $515.3 million for the year ended December 31, 2014. The ratio of gross profit to net sales was 44.3% for 2015 compared to 45.4% in 2014. The lower gross profit ratio in 2015 was primarily related to a less favorable product mix, increased indirect costs, and increased amortization related to the Latchways acquisition.

Selling, general and administrative expenses. Selling, general and administrative expenses were $315.3 million for the year ended December 31, 2015, a decrease of $7.5 million, or 2%, from $322.8 million for the year ended December 31, 2014. Selling, general and administrative expenses were 27.9% of net sales in 2015 compared to 28.5% of net sales in 2014. Local currency selling, general and administrative expenses increased 6% in the current period, primarily reflecting Latchways acquisition related costs of $7.5 million and Latchways operating selling, general and administrative costs of $3.2 million. Please refer to the Selling, general and administrative expenses table for a reconciliation of the year over year expense change.

Selling, general, and administrative expenses	Year Ended December 31, 2015 versus December 31, 2014
(Percent Change)	Consolidated Continuing Operations
GAAP reported change	(2.3)%
Currency translation effects	(8.3)%
Constant currency change	6.0%
Acquisitions and related strategic transaction costs	3.4%
Organic constant currency change	2.6%

Note: Organic constant currency change is a non-GAAP financial measure provided by the Company to give a better understanding of the Company's underlying business performance. Organic constant currency change in selling, general, and administrative expenses is calculated by removing the percentage impact from acquisitions and currency translation effects from the overall percentage change in GAAP selling, general, and administrative expense. Management believes excluding acquisitions and currency translation effects provide investors with a greater level of clarity into spending levels on a year-over-year basis.

25

Research and development expenses. Research and development expense was $48.6 million for the year ended December 31, 2015, increase of $0.4 million, or 1%, compared to $48.2 million for the year ended December 31, 2014. Research and development expenses were 4.3% of net sales in both 2015 and 2014, which is in line with our target ratio of 4.0% - 4.5% of net sales. The Company continues to focus on developing new and innovative technologies, closely aligned with our strategic goals.

Restructuring and other charges. During the year ended December 31, 2015, the Company recorded charges of $12.3 million, an increase of $3.8 million, or 45%, compared to charges of $8.5 million for the year ended December 31, 2014. At December 31, 2015, the Company had accrued restructuring costs of $8.1 million, primarily related to severance costs associated with our global cost reduction program.

Currency exchange. Currency exchange losses were $2.2 million during the year ended December 31, 2015, compared to losses of $1.5 million during the year ended December 31, 2014. Currency exchange losses in both periods were mostly unrealized and related primarily to the effect of the strengthening US dollar on inter-company balances. Refer to Note 17 to the Consolidated Financial Statements in Part I Item I of this Form 10-Q, for information regarding our currency exchange rate risk management strategy.

GAAP operating income. Consolidated operating income for the year ended December 31, 2015 was $122.7 million, a decrease of $11.6 million, or 9%, compared to $134.3 million for the year ended December 31, 2014.

Adjusted operating income. Americas adjusted operating income for the year ended December 31, 2015 was $142.0 million, an increase of $7.2 million, or 5%, compared to $134.8 million for the year ended December 31, 2014. The increase in Americas adjusted operating income reflects higher sales, notably in the fire sector, and controlled selling, general, and administrative spending.

International adjusted operating income for the year ended December 31, 2015 was $33.5 million, a decrease of $13.3 million, or 28%, compared to $46.8 million for the year ended December 31, 2014. The decrease in International adjusted operating income reflects a lower level of sales, higher pension costs, and higher restructuring costs associated with initiatives to right-size our operations in accordance with our global cost reduction program.

Corporate segment adjusted operating loss for the year ended December 31, 2015 was $38.3 million, an increase of $0.9 million, or 2%, compared to an operating loss of $37.4 million for the year ended December 31, 2014, reflecting higher costs associated with our acquisition and integration of Latchways as well as higher restructuring costs associated with our global cost reduction efforts.

The following table represents a reconciliation from GAAP operating income to adjusted operating income. Adjusted operating margin % is calculated as adjusted operating income divided by net sales.

Adjusted operating income	Year Ended December 31, 2015
(In thousands)	Americas	International	Corporate	Consolidated Continuing Operations
Net sales	$704,754	$426,029	$—	$1,130,783
GAAP operating income				122,741
Restructuring and other charges				12,258
Currency exchange losses, net				2,204
Adjusted operating income	$141,971	$33,501	$(38,269)	$137,203
Adjusted operating margin %	20.1%	7.9%

Note: Adjusted operating income is a non-GAAP financial measure used by the chief operating decision maker to evaluate segment performance and allocate resources. Adjusted operating income is reconciled above to the nearest GAAP financial measure, Operating income.

Total other expense, net. Other expense for the year ended December 31, 2015 was $11.7 million, compared to $7.1 million for the year ended December 31, 2014. The increase in other expense is primarily the result of the disposal of net assets which resulted in a net loss of $0.9 million in 2015 versus a $2.2 million gain in 2014. Refer to Note 15 of the Consolidated Financial Statements in Part II Item 8 of this Form 10-K for more information.

26

Income taxes. Our effective tax rate from continuing operations for the year ended December 31, 2015 was 40.0% compared to 32.3% for the year ended December 31, 2014. The effective tax rate for December 31, 2015 included 6.9% associated with exit taxes related to our European reorganization. The remaining effective tax rate increase was primarily due to non-deductible losses in certain foreign jurisdictions.

Net income from continuing operations attributable to MSA Safety Incorporated. Net income from continuing operations was $69.6 million for the year ended December 31, 2015, or $1.84 per diluted share, a decrease of $17.8 million, or 20%, compared to $87.4 million, or $2.30 per diluted share, for the year ended December 31, 2014 as a result of the factors described above.

Net income from discontinued operations attributable to MSA Safety Incorporated. Net income from discontinued operations was $1.2 million for the year ended December 31, 2015, or $0.03 per diluted share, compared to net income of $1.1 million, or $0.03 per diluted share, for the year ended December 31, 2014. Please refer to Note 20 to the Consolidated Financial Statements in Part II Item 8 of this Form 10-K.

Non-GAAP Financial Information

We may provide information regarding organic constant currency changes, financial measures excluding the impact of acquisitions, and adjusted operating income, which are not recognized terms under U.S. GAAP and do not purport to be alternatives to net sales, selling, general and administrative expense, operating income, or net income as a measure of operating performance. We believe that the use of these non-GAAP financial measures provide investors with additional useful information and provide a more complete understanding of the underlying results. Because not all companies use identical calculations, these presentations may not be comparable to similarly titled measures from other companies. For more information about these non-GAAP measures and a reconciliation to the nearest GAAP measure, please refer to the reconciliations referenced above in Management's Discussion & Analysis section and in Note 7 to the consolidated financial statements In Part II Item 8 of this Form 10-K.

We also refer to certain financial measures on a constant currency basis, which is a non-GAAP financial measure. These references to a constant currency basis do not include operational impacts that could result from fluctuations in foreign currency rates, which are outside of management's control. To provide information on a constant currency basis, the applicable financial results are adjusted by translating current and prior period results in local currency to a fixed foreign exchange rate. This approach is used for countries where the functional currency is the local country currency. This information is provided so that certain financial results can be viewed without the impact of fluctuations in foreign currency rates, thereby facilitating period-to-period comparisons of business performance. Constant currency information is not recognized under U.S. GAAP, and it is not intended as an alternative to U.S. GAAP measures.

LIQUIDITY AND CAPITAL RESOURCES

Our main source of liquidity is operating cash flows, supplemented by borrowings. Our principal liquidity requirements are for working capital, capital expenditures, principal and interest payments on debt, dividend payments, and acquisitions. At December 31, 2016, approximately 51% of our long-term debt is at fixed interest rates with repayment schedules through 2031. The remainder of our long-term debt is at variable rates on an unsecured revolving credit facility that is due in 2020. Approximately 80% of our borrowings are denominated in US dollars, which limits our exposure to currency exchange rate fluctuations.

At December 31, 2016, we had cash and cash equivalents totaling $113.8 million, of which $106.9 million was held by our foreign subsidiaries. The $106.9 million of cash and cash equivalents are held by our foreign subsidiaries whose earnings are considered indefinitely reinvested at December 31, 2016. These funds could be subject to additional income taxes if repatriated. It is not practical to determine the potential income tax liability that we would incur if these funds were repatriated to the U.S. because the time and manner of repatriation is uncertain. We believe that domestic cash and cash equivalents, domestic cash flows from operations, annual repatriation of a portion of the current period's foreign earnings, and the availability of our domestic line of credit are sufficient to fund our domestic liquidity requirements. Cash and cash equivalents increased $7.8 million during the year ended December 31, 2016, compared to an decrease of $0.1 million during 2015 and an increase of $9.7 million during 2014.

Our unsecured senior revolving credit facility provides for borrowings up to $575.0 million through 2020 and is subject to certain commitment fees. This credit facility has sub-limits for the issuance of letters of credit, swingline borrowings and foreign currency denominated borrowings; and may be used for general corporate purposes, including working capital, permitted acquisitions, capital expenditures and repayment of existing indebtedness. Loans under the revolving facility will bear interest, at a variable rate based on LIBOR or the federal funds rate, at the Company's option. Our weighted average interest rate was 2.27% in 2016. At December 31, 2016, $377.2 million of the $575.0 million senior revolving credit facility was unused, including letters of credit.

The Company currently has access to approximately $572.2 million of capital at December 31, 2016. Refer to Note 11 Short and Long- Term Debt to the Consolidated Financial Statements in Part II Item 8 of this Form 10-K.

Operating activities. Operating activities provided cash of $134.9 million in 2016, compared to providing cash of $55.3 million in 2015. The increase in operating cash flow during 2016 was primarily attributable to higher net income and lower working capital driven by collections of accounts receivable and our ongoing focus on inventory management. Working capital as a percentage of sales improved by 400 bps to 21.7% in 2016 as compared to 25.7% in 2015. At December 31, 2016, working capital included trade receivables, inventory and accounts payable of $1.1 million, $3.3 million and $0.9 million, respectively related to the acquisition of Senscient.

Operating activities provided cash of $55.3 million in 2015, compared to providing cash of $107.0 million in 2014. Lower operating cash flow in 2015 is primarily related to lower profitability in 2015 and changes in working capital. Trade receivables were $232.9 million at December 31, 2015 compared to $211.4 million at December 31, 2014, reflecting strong G1 SCBA sales results in the 2015 fourth quarter partially offset by a decrease due to currency translation effects. Inventories were $125.8 million at December 31, 2015 increased $2.8 million as compared to $123.0 million at December 31, 2014 due to the acquisition of Latchways and continued demand planning for our G1 SCBA. Currency translation effects of $16.4 million decreased inventories. Accounts payable were $68.2 million at December 31, 2015 compared to $70.2 million at December 31, 2014 primarily due to a decrease for currency translation effects. The December 31, 2015 trade receivables and inventory balances included Latchways trade receivables and inventory of $11.8 million and $9.1 million, respectively.

Investing activities. Investing activities used cash of $25.8 million for the year ended December 31, 2016, compared to using $208.5 million in 2015. The acquisition of Senscient drove cash outflows from investing activities during 2016 while the acquisition of Latchways drove cash outflows from investing activities during 2015. Capital expenditures were $25.5 million in 2016 compared to $36.2 million in 2015. Capital expenditures in 2015 included spending related to initiatives such as the G1 SCBA and our European reorganization. We plan to invest approximately $30.0 million in capital expenditures in 2017.

Investing activities used cash of $208.5 million for the year ended December 31, 2015, compared to using $30.7 million in 2014. The increased use of cash for investing activities in 2015 was related to the acquisition of Latchways. Cash generated from property disposals was $8.0 million in 2015 compared to $3.4 million in 2014. The cash received from property disposals in 2015 include proceeds from the sale of property in Australia. Capital expenditures were $36.2 million compared to $33.6 million in 2014.

Financing activities. Financing activities used cash of $97.8 million for the year ended December 31, 2016, compared to providing cash of $164.9 million in 2015. During 2016, we had net payments on debt of $60.9 million. This compared to net proceeds from borrowings of $218.9 million in the same period in 2015 primarily related to the financing of the Latchways acquisition.

We made dividend payments of $49.1 million during 2016, compared to $47.4 million million during 2015. Dividends paid on our common stock during 2016 were $1.31 per share. Dividends paid on our common stock in 2015 and 2014 were $1.27 and $1.23 per share, respectively.

Restricted cash balances were $1.2 million at December 31, 2016 compared to $2.4 million at December 31, 2015 and were primarily used to support letter of credit balances.

During 2015, the MSA Board of Directors authorized the Company to repurchase up to $100.0 million in shares of MSA common stock and we executed share repurchases of $7.1 million. There were no share repurchases in 2016. The program seeks to offset equity dilution associated with employee stock compensation. The Board of Directors did not set a time limitation on the repurchase program.

Financing activities provided cash of $164.9 million for the year ended December 31, 2015, compared to using cash of $58.1 million in 2014. The change was primarily related to borrowings made to finance the acquisition of Latchways in 2015.

CUMULATIVE TRANSLATION ADJUSTMENTS

The year-end position of the U.S. dollar relative to international currencies resulted in a translation loss of $25.9 million being recorded to cumulative translation adjustments for the year ended December 31, 2016. This compares to losses of $47.7 million in 2015 and $40.0 million in 2014. The translation loss in 2016 was primarily related to the strengthening of the U.S. dollar against the British pound, Mexican peso, Argentine peso, euro, and Brazilian real. The translation loss in 2015 was primarily related to the strengthening of the U.S. dollar against the euro, British pound, Brazilian real, and South African rand. The translation loss in 2014 was primarily related to the weakening of the euro, Mexican peso, Argentine peso, and the South African rand.

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, 2016 are as follows:

(In millions)	Total		2017		2018		2019		2020		2021		Thereafter
Long-term debt	$	392.3	$	26.7	$	26.7	$	26.7	$	217.7	$	26.7	$	67.8
Operating leases	50.2		12.2		11.0		10.6		5.2		4.2		7.0
Totals	442.5		38.9		37.7		37.3		222.9		30.9		74.8

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 2017, 2018 and 2019 debt service obligations through cash provided by operations. Approximately $191.0 million of debt payable in 2020 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 2020, we expect to refinance the remaining balance through new borrowing facilities. Interest expense on fixed rate debt over the next five years is expected to be approximately $8.1 million in 2017, $6.9 million in 2018, $5.8 million in 2019, $4.6 million in 2020, and $3.6 million in 2021.

The Company had outstanding bank guarantees and standby letters of credit with banks as of December 31, 2016 totaling $13.1 million, of which $6.9million relate to the senior revolving credit facility. These letters of credit serve to cover customer requirements in connection with certain sales orders and insurance companies. No amounts were drawn on these arrangements at December 31, 2016. The Company is also required to provide cash collateral in connection with certain arrangements. At December 31, 2016, the Company has $1.2 million of restricted cash in support of these arrangements.

We expect to make net contributions of $5.9 million to our pension plans in 2017 which are primarily associated with our International segment. We have not been required to make contributions to our U.S. based qualified defined benefit pension plan in many years.

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

Please refer to Note 19 Contingencies to the Consolidated Financial Statements in Part II Item 8 of this Form 10-K for further discussion on the Company's product liabilities.

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 consolidated financial statements. A summary of the Company's significant accounting policies is included in Note 1 to the Consolidated Financial Statements in Part II, Item 8 of this Form 10-K.

We believe that the following are the more critical judgments and estimates used in the preparation of our consolidated 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 consolidated 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. The Company categorizes the product liability losses of its subsidiary MSA LLC into two main categories: single incident and cumulative trauma.

29

Single incident claims. Single incident product liability claims involve incidents of short duration that are typically known to us when they occur and involve observable injuries, which provide an objective basis for quantifying damages. MSA LLC estimates its liability for single incident product liability claims based on expected settlement costs for reported claims and an estimate of costs for unreported claims (claims incurred but not reported or IBNR). The estimate for IBNR claims is based on experience, sales volumes, and other relevant information. The reserve for single incident product liability claims, which includes reported and IBNR claims, was $3.4 million at December 31, 2016 and $3.5 million at December 31, 2015. Single incident product liability expense during the year ended December 31, 2016 was $0.8 million and was $0.9 million for the year ended December 31, 2015. Single incident product liability exposures are evaluated on an annual basis, or more frequently if changing circumstances warrant. Adjustments are made to the reserve as appropriate.

Cumulative trauma claims. 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, mesothelioma, or coal worker’s pneumoconiosis. MSA LLC is presently named as a defendant in 1,794 lawsuits comprised of 3,023 claims. These lawsuits mainly involve respiratory protection products allegedly manufactured and sold by MSA LLC or its predecessors. The products at issue were manufactured many years ago and are not currently offered by MSA LLC. Although there is year over year variability in the number and quality of claims defended and resolved, MSA LLC’s aggregate spend for cumulative trauma product liability claims (inclusive of settlements and defense costs) for the three years ended December 31, 2016, totaled approximately $150.9 million, substantially all of which was recorded as insurance receivables because the amounts are believed to be recoverable under insurance.

More than half of the open lawsuits at December 31, 2016 have had a de minimis level of activity over the last 5 years. It is possible that these cases could become active again at any time due to changes in circumstances.

Management works with its outside valuation consultant and outside legal counsel to review its cumulative trauma product liability exposure on an annual basis, or more frequently if changing circumstances or developments in existing cases make an interim review appropriate. The review process takes into account the number and composition of pending claims, outcomes of matters resolved during current and prior periods, and variances associated with different plaintiffs’ counsel and venues, as well as other information known about the current docket.

Cumulative trauma product liability litigation is inherently unpredictable. Factors that can limit our ability to estimate potential liability include the lack of claims experience with applicable plaintiffs’ counsel, as claims experience can vary significantly among different counsel, low volume of resolution, lack of confidence with the consistency of claims composition, or other factors. With respect to the risk associated with any particular case, it has typically not been until very late in the legal process that it can be reasonably determined whether it is probable that any such case will ultimately result in a liability. This uncertainty is caused by many factors, including consideration of the applicable statute of limitations, the sufficiency of product identification and other defenses. Complaints generally do not provide information sufficient to determine if a lawsuit will develop into an actively litigated case. 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 if it is probable that such a lawsuit will result in a loss, it is often difficult to estimate the amount of actual loss that will be incurred. These actual loss amounts are highly variable and turn on a case by case analysis of the relevant facts, including the nature of the injury, the jurisdiction in which the claim is filed, the plaintiffs' counsel and the number of parties in the lawsuit. In addition, there are uncertainties concerning the impact of bankruptcies of other companies that are co-defendants in claims, uncertainties surrounding the litigation process from jurisdiction to jurisdiction and case to case. Consequently, MSA LLC is unable to comprehensively estimate its cumulative trauma product liability exposure.

Currently, management, in consultation with its outside valuation consultant and outside legal counsel, has been unable to estimate, and therefore has not recorded any liability, for MSA LLC’s incurred but not reported claims (“IBNR claims") as well as for certain of its existing coal dust claims, including those coal dust claims that arose subsequent to the Couch verdict. (Please refer to Note 19 Contingencies of the Consolidated Financial Statements in Part II Item 8 of this Form 10-K for further details on the Couch verdict.)

MSA LLC recorded a liability of $7.5 million and $7.1 million as of December 31, 2016 and 2015, respectively, pertaining to certain reported claims where MSA LLC’s claims experience allowed it to make an estimate of potential liability. To arrive at the estimate, it was necessary to employ significant assumptions. The reserve does not include amounts which will be spent to defend the claims covered by the reserve. These costs are recognized as incurred.

As noted above, the liability recorded does not take into account any IBNR claims and certain of the currently pending coal dust claims against MSA LLC. These claims have not been included in the reserve due to a lack of claims experience with the applicable plaintiffs’ counsel, low volume of resolution, or lack of confidence in the consistency of claims composition, or other factors, which have rendered us unable to reasonably assess the probability and estimate the magnitude of potential losses.

30

Because litigation is subject to inherent uncertainties, and unfavorable rulings or developments could occur, there can be no certainty that MSA LLC may not ultimately incur charges in excess of presently recorded liabilities with respect to claims included within the existing reserve or related to claims not included in the reserve. We will adjust the reserve for our liability relating to cumulative trauma claims from time to time based on the maturation of claims, developing facts and circumstances, and if actual experience is worse than previously projected. These adjustments may reflect changes in estimates for claims currently covered by the reserve, as well as estimated liabilities for claims not presently covered by the reserve and IBNR claims, in the event we become able to reasonably assess the probability and estimate the magnitude of potential losses. These adjustments may be material and could increase the year over year variability of our financial results.

Income taxes. We recognize deferred tax assets and liabilities using enacted tax rates to record the tax 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 $5.3 million and $5.2 million at December 31, 2016 and 2015, 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.

No deferred U.S. income taxes have been provided on undistributed earnings of non-U.S. subsidiaries, which amounted to $422.3 million as of December 31, 2016. These earnings are considered to be reinvested for an indefinite period of time. Because we currently do not have any plans to repatriate these funds, we cannot determine the impact of local taxes, withholding taxes and foreign tax credits associated with the future repatriation of such earnings and, therefore, cannot reasonably estimate the associated tax liability. In cases where we intend to repatriate a portion of the undistributed earnings of our foreign subsidiaries, we provide U.S. income taxes on such earnings.

Pensions and other post-retirement benefits. We sponsor certain pension and other post-retirement 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. Discount rates and plan asset valuations are point-in-time measures. 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. Expected returns on plan assets are based on our historical returns by asset class.

Please refer to Note 14 to the Consolidated Financial Statements in Part II Item 8 of this Form 10-K for further details on the funded status of our pension and post-retirement benefit plans.

The following table summarizes the impact of changes in significant actuarial assumptions on our December 31, 2016 actuarial valuations.

	Impact of Changes in Actuarial Assumptions
	Change in Discount Rate						Change in Expected Return					Change in Market Value of Assets
(In thousands)	1%			(1)%			1%			(1)%		5%			(5)%

Increase (decrease) in funded status	65,405			(78,832		)	—			—		21,663			(21,663		)

Stock Compensation. We sponsor both a Management and a Non-Employee Directors' Equity Incentive plan which provide for grants of stock options, restricted stock and other equity-based vehicles such as restricted stock units and performance stock units; all of which are recognized as compensation expense based on grant date fair value. Stock options are

31

valued using the Black-Scholes option pricing model. Performance stock units that have a market condition are valued on the grant date using a Monte Carlo simulation valuation model. We believe these valuation models are appropriate for use based and are consistent with models used by our peer companies. Please refer to Note 10 to the Consolidated Financial Statements in Part II Item 8 of this Form 10-K for further details on the assumptions used in these valuation models.

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 distributor'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.

Goodwill. In the fourth quarter of each year, or more frequently if indicators of impairment exist or if a decision is made to sell a business, we evaluate goodwill for impairment. A significant amount of judgment is involved in determining if an indicator of impairment has occurred. Such indicators may include a decline in expected cash flows, a significant adverse change in the business climate, unanticipated competition, slower growth rates, or negative developments in equity and credit markets, among others.

All goodwill is assigned to and evaluated for impairment at the reporting unit level, which is defined as an operating segment or one level below an operating segment. For goodwill impairment testing purposes, we consider our operating segments to be our reporting units. The evaluation of impairment involves using either a qualitative or quantitative approach as outlined in Accounting Standards Codification (ASC) Topic 350. The qualitative evaluation is an assessment of factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value, including goodwill. Factors considered as part of the qualitative assessment include entity-specific industry, market and general economic conditions. In 2016, we elected to bypass the qualitative evaluation for all of our reporting units and performed a two-step quantitative test at October 1, 2016. Quantitative testing involves comparing the estimated fair value of each reporting unit to its carrying value. We estimate reporting unit fair value using a weighted average of fair values determined by discounted cash flow (DCF) and market approach methodologies, as we believe both are equally important indicators of fair value. A number of significant assumptions and estimates are involved in the application of the DCF model, including sales volumes and prices, costs to produce, tax rates, capital spending, discount rates, and working capital changes. Cash flow forecasts are generally based on approved business unit operating plans for the early years and historical relationships in later years. The betas used in calculating the individual reporting units’ weighted average cost of capital (WACC) rate are estimated for each reporting unit based on peer data. The market approach methodology measures value through an analysis of peer companies. The analysis entails measuring the multiples of EBITDA at which peer companies are trading.

In the event the estimated fair value of a reporting unit per the weighted average of the DCF and market approach models is less than the carrying value, additional analysis would be required. The additional analysis would compare the carrying amount of the reporting unit’s goodwill with the implied fair value of that goodwill, which may involve the use of valuation experts. The implied fair value of goodwill is the excess of the fair value of the reporting unit over the fair value amounts assigned to all of the assets and liabilities of that unit as if the reporting unit had been acquired in a business combination and the fair value of the reporting unit represented the purchase price. If the carrying value of goodwill exceeds its implied fair value, an impairment loss equal to such excess would be recognized, which could significantly and adversely impact reported consolidated results of operations and shareholders’ equity. At October 1, 2016, based on our quantitative test, the fair values of all of our reporting units exceeded their carrying value by at least 40%.

Foreign currency. As part of our currency exchange rate risk management strategy, we enter into certain derivative foreign currency forward contracts that do not meet the U.S. GAAP criteria for hedge accounting, but which have the impact of partially offsetting certain foreign currency exposures. We account for these forward contracts on a full mark-to-market basis and report the related gains or losses in currency exchange losses (gains) in the consolidated statement of income. Please refer to Note 17 to the Consolidated Financial Statements in Part II Item 8 of this Form 10-K for further details on our current positions.

RECENTLY ADOPTED AND RECENTLY ISSUED ACCOUNTING STANDARDS

In April 2014, the FASB issued ASU 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of an Entity. This ASU amends the definition of a discontinued operation to include a disposal of a component or group of components that is disposed of or is classified as held for sale and represents a strategic shift that has (or will have) a major effect on an entity's operations and financial results. This ASU was adopted on January 1, 2015. The adoption of this ASU may have a material effect on our consolidated financial statements in the event that we were to divest of a component that meets the definition of discontinued operations.

In May 2014, the FASB issued ASU 2014-09, Revenue with Contracts from Customers. This ASU establishes a single revenue recognition model for all contracts with customers based on recognizing revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services, eliminates industry specific requirements, and expands disclosure requirements. This ASU is required to be adopted beginning January 1, 2018. Our revenue streams include agreements with distributors, agreements with end users and agreements with governmental entities. The Company continues to evaluate the impact that the adoption of this ASU will have on the consolidated financial statements, including the timing of revenue recognition associated with certain customized products. We have conducted a risk assessment and have worked with outside consultants to develop a transition plan that will enable us to meet the implementation requirement. We are currently in the process of reviewing and analyzing contracts. We anticipate using the modified retrospective method of adoption and having enhanced disclosures surrounding revenue recognition.

This ASU was adopted on January 1, 2016. The adoption of this ASU did not have a material effect on our consolidated financial statements.

In September 2015, the FASB issued ASU 2015-16, Simplifying the Accounting for Measurement-Period Adjustments. This ASU simplifies the accounting for adjustments made to provisional amounts recognized in a business combination. The amendments in this Update eliminate the requirement to retrospectively account for those adjustments. MSA elected to early adopt this standard for the period ended December 31, 2015. The adoption of this ASU could have a material effect on our consolidated financial statements to the extent that measurement-period adjustments for business combinations are identified.

In February 2016, the FASB issued ASU 2016-02, Leases. This ASU requires lessees to record a right of use asset and a liability for virtually all leases. This ASU will be effective beginning in 2019. The Company continues to evaluate the impact that the adoption of this ASU will have on the consolidated financial statements.

In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting. This ASU simplifies the accounting for many aspects associated with share-based payment accounting including income taxes and the use of forfeiture rates. This ASU will be effective beginning in 2017. The Company is currently evaluating the impact that the adoption of these ASU will have on the consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, Allowance for Loan and Lease Losses. This ASU introduces an approach based on expected losses to estimate credit losses on certain types of financial instruments including loans, held-to-maturity debt securities, loan commitments, financial guarantees and net investments in leases as well as reinsurance and trade receivables. This ASU will be effective beginning in 2020. The Company is currently evaluating the impact that the adoption of these ASU will have on the consolidated financial statements and expects that adoption will result in increased disclosure.

In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Payments and Cash Receipts. This ASU clarifies how certain cash receipts and cash payments are presented and classified in the statement of cash flows. This ASU will be effective beginning in 2018. The Company is currently evaluating the impact that the adoption of these ASU will have on the consolidated financial statements.

In October 2016, the FASB issued ASU 2016-16, Intra-entity Transfers of Assets Other than Inventory. This ASU states that an entity should recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. This ASU is effective beginning in 2018 to be adopted on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings and early adoption is permitted. The Company is currently evaluating the impact that the adoption of these ASU will have on the consolidated financial statements.

In November 2016, the FASB issued ASU 2016-18, Restricted Cash. This ASU requires that amounts generally described as restricted cash and restricted cash equivalents are included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. This ASU is effective beginning in 2018 to be adopted on a retrospective basis and early adoption is permitted. The Company is currently evaluating the impact that the adoption of these ASU will have on the consolidated financial statements.

In January 2017, the FASB issued ASU 2017-01, Business Combinations - Clarifying the Definition of a Business. This ASU provides further guidance for identifying whether a set of assets and activities is a business by providing a screen outlining that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This ASU is effective beginning in 2018 and will be applied prospectively. The adoption of this ASU may have a material effect on our consolidated financial statements in the event that we have an acquisition or disposal that falls within this screen.

In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment. This ASU simplifies the accounting for goodwill impairments under Step 2 by eliminating the requirement to perform procedures to determine the fair value of the assets and liabilities of the reporting unit, including previously unrecognized assets and liabilities, in order to determine the fair value of the goodwill and any impairment charge to be recognized. Under this ASU, the impairment charge to be recognized should be the amount by which the reporting unit's carrying value exceeds the reporting unit's fair value as calculated under Step 1 provided that the loss recognized should not exceed the total amount of goodwill allocated to the reporting unit. This ASU is effective beginning in 2019 for public entities and early adoption is permitted for interim or annual goodwill impairment tests performed after January 1, 2017. The adoption of this ASU may have a material effect on our consolidated financial statements in the event that we determine that goodwill for any of our reporting units is impaired.

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 rates. 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, 2016 by approximately $53.5 million and $6.1 million, or 4.7% and 6.6%, respectively.

When appropriate, we may attempt to limit our transactional exposure to changes in currency exchange rates through forward contracts or other actions intended to reduce existing exposures by creating offsetting currency exposures. At December 31, 2016, we had open foreign currency forward contracts with a U.S. dollar notional value of $75.3 million. A hypothetical 10% increase in December 31, 2016 forward exchange rates would result in a $7.5 million increase in the fair value of these contracts.

Interest rates. 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 our revolving credit facility, these financial instruments are reported at carrying values which approximate fair values.

At December 31, 2016, we had $201.2 million million of fixed rate debt which matures at various dates through 2031. 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 $14.4 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.

At December 31, 2016, we had $191.0 million of variable rate borrowings under our revolving credit facility. A 100 basis point increase or decrease in interest rates could have an impact on future earnings under our current capital structure.

Management’s Reports to Shareholders

Management’s Report on Responsibility for Financial Reporting

Management of MSA Safety Incorporated (the Company) is responsible for the preparation of the consolidated financial statements included in this annual report. The consolidated 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 consolidated 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, 2016. 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 (2013). Based on our assessment and those criteria, management has concluded that the Company maintained effective internal control over financial reporting as of December 31, 2016.

Management has excluded Senscient, Inc. (Senscient) from its assessment of internal controls over financial reporting as of December 31, 2016 because the Company acquired Senscient effective September 19, 2016 (Acquisition Date), whose total assets represents 3%, and net loss represents 1%, and whose customer revenues represents less than 0.5% of the related consolidated financial statement amounts as of December 31, 2016 and from the period from the acquisition date through December 31, 2016.

The Company's independent registered public accounting firm that audited the consolidated financial statements included in this annual report issued an attestation report on the Company's internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders of MSA Safety Incorporated:

We have audited MSA Safety Incorporated’s internal control over financial reporting as of December 31, 2016, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 Framework) (the COSO criteria). MSA Safety Incorporated’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

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

Because of 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.

As indicated in the accompanying Management’s Report on Internal Control Over Financial Reporting, management’s assessment of and conclusion on the effectiveness of internal control over financial reporting did not include the internal controls of Senscient, Inc., which is included in the 2016 consolidated financial statements of MSA Safety Incorporated and constituted 3% and 6% of total and net assets, respectively, as of December 31, 2016, and less than 1% of revenues and net income, respectively, for the year then ended. Our audit of internal control over financial reporting of MSA Safety Incorporated also did not include an evaluation of the internal control over financial reporting of Senscient, Inc.

In our opinion, MSA Safety Incorporated maintained, in all material respects, effective internal control over financial reporting as of December 31, 2016, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of MSA Safety Incorporated as of December 31, 2016 and 2015, and the related consolidated statements of income, comprehensive income, cash flows, changes in retained earnings and accumulated other comprehensive loss for each of the two years in the period ended December 31, 2016 of MSA Safety Incorporated and our report dated February 28, 2017, expressed an unqualified opinion thereon.

MSA SAFETY INCORPORATED

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1—Significant Accounting Policies

Basis of Presentation—The Consolidated Financial Statements of MSA Safety Incorporated ("MSA" or "the Company") are prepared in conformity with accounting principles generally accepted in the United States of America (GAAP) and require management to make certain judgments, estimates, and assumptions. These may affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements. They also may affect the reported amounts of revenues and expenses during the period. Actual results could differ from those estimates upon subsequent resolution of identified matters.

Certain segment results in previously issued consolidated financial statements were recast to conform to the current period presentation. Refer to Note 7 for further information regarding MSA's segment allocation methodology.

Principles of Consolidation—The consolidated financial statements include the accounts of the Company and all subsidiaries. Intercompany accounts and transactions are eliminated.

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

Restricted Cash—Restricted cash, which is designated for use other than current operations, is included in prepaid expenses and other current assets in the Consolidated Balance Sheet. Restricted cash balances were $1.2 million and $2.4 million at December 31, 2016 and December 31, 2015, respectively. These balances were used to support letter of credit balances.

Inventories—Inventories are stated at the lower of cost or market. The majority of 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. It is the Company’s general policy to write-down any inventory that is identified as obsolete and any inventory that has aged or has not moved in more than twenty-four months.

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 other income and the cost and related depreciation are removed from the accounts. Depreciation expense for the years ended December 31, 2016, 2015 and 2014 was $27.0 million, $26.9 million and $26.2 million, respectively. Properties, plants, and equipment are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of assets is determined by comparing the estimated undiscounted net cash flows of the operations related to the assets to their carrying amount. An impairment loss would be recognized when the carrying amount of the assets exceeds the estimated undiscounted net cash flows. The amount of the impairment loss to be recorded is calculated as the excess of the carrying value of the assets over their fair value, with fair value determined using the best information available, which generally is a discounted cash flow model.

45

Goodwill and Other Intangible Assets—Intangible assets with a finite useful life are amortized on a straight-line basis over their useful lives. Indefinite lived intangible assets are assessed for possible impairment annually or whenever circumstances change such that the recorded value of the asset may not be recoverable. Goodwill is not amortized, but is subject to impairment assessments. In the fourth quarter of each year, or more frequently if indicators of impairment exist or if a decision is made to sell a business, we evaluate goodwill for impairment. A significant amount of judgment is involved in determining if an indicator of impairment has occurred. Such indicators may include a decline in expected cash flows, a significant adverse change in the business climate, unanticipated competition, slower growth rates, or negative developments in equity and credit markets, among others.

All goodwill is assigned to and evaluated for impairment at the reporting unit level, which is defined as an operating segment or one level below an operating segment. For goodwill impairment testing purposes, we consider our operating segments to be our reporting units. The evaluation of impairment involves using either a qualitative or quantitative approach as outlined in Accounting Standards Codification (ASC) Topic 350. The qualitative evaluation is an assessment of factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value, including goodwill. Factors considered as part of the qualitative assessment include entity-specific industry, market and general economic conditions. In 2016, we elected to bypass the qualitative evaluation for all of our reporting units and performed a two-step quantitative test at October 1, 2016. Step 1 of the quantitative testing involves comparing the estimated fair value of each reporting unit to its carrying value. We estimate reporting unit fair value using a weighted average of fair values determined by discounted cash flow (DCF) and market approach methodologies, as we believe both are equally important indicators of fair value. A number of significant assumptions and estimates are involved in the application of the DCF model, including sales volumes and prices, costs to produce, tax rates, capital spending, discount rates, and working capital changes. Cash flow forecasts are generally based on approved business unit operating plans for the early years and historical relationships in later years. The betas used in calculating the individual reporting units’ weighted average cost of capital (WACC) rate are estimated for each reporting unit based on peer data. The market approach methodology measures value through an analysis of peer companies. The analysis entails measuring the multiples of EBITDA at which peer companies are trading.

In the event the estimated fair value of a reporting unit per the weighted average of the DCF and market approach models is less than the carrying value, Step 2 of the analysis would be required. The additional analysis would compare the carrying amount of the reporting unit’s goodwill with the implied fair value of that goodwill, which may involve the use of valuation specialist. The implied fair value of goodwill is the excess of the fair value of the reporting unit over the fair value amounts assigned to all of the assets and liabilities of that unit as if the reporting unit had been acquired in a business combination and the fair value of the reporting unit represented the purchase price. If the carrying value of goodwill exceeds its implied fair value, an impairment loss equal to such excess would be recognized, which could significantly and adversely impact reported consolidated results of operations and shareholders’ equity. There has been no impairment of our goodwill as of December 31, 2016, 2015 or 2014.

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 distributor'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.

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.

46

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. 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 consolidated statements of income as currency exchange (income) loss in the current period.

Commitments and Contingencies—For asserted claims and assessments, liabilities are recorded when an unfavorable outcome of a matter is deemed to be probable and the loss is reasonably estimable. Management determines the likelihood of an unfavorable outcome based on many factors such as the nature of the matter, available defenses and case strategy, progress of the matter, views and opinions of legal counsel and other advisors, applicability and success of appeals processes, and the outcome of similar historical matters, among others. Once an unfavorable outcome is deemed probable, management weighs the probability of estimated losses, and the most reasonable loss estimate is recorded. If an unfavorable outcome of a matter is deemed to be reasonably possible, then the matter is disclosed and no liability is recorded. With respect to unasserted claims or assessments, management must first determine that the probability that an assertion will be made is likely, then, a determination as to the likelihood of an unfavorable outcome and the ability to reasonably estimate the potential loss is made. Legal matters are reviewed on a continuous basis to determine if there has been a change in management’s judgment regarding the likelihood of an unfavorable outcome or the estimate of a potential loss. Please refer to Note 19 Contingencies for further details on product liability related matters.

Discontinued Operations and Assets Held For Sale—For those businesses where management has committed to a plan to divest, each business is valued at the lower of its carrying amount or estimated fair value less cost to sell. If the carrying amount of the business exceeds its estimated fair value, an impairment loss is recognized. Fair value is estimated using accepted valuation techniques such as a discounted cash flow model, valuations performed by third parties, earnings multiples, or indicative bids, when available. A number of significant estimates and assumptions are involved in the application of these techniques, including the forecasting of markets and market share, sales volumes and prices, costs and expenses, and multiple other factors. Management considers historical experience and all available information at the time the estimates are made; however, the fair value that is ultimately realized upon the divestiture of a business may differ from the estimated fair value reflected in the Consolidated Financial Statements. Depreciation and amortization expense is not recorded on assets of a business to be divested once they are classified as held for sale.

For businesses classified as discontinued operations, the results of operations are reclassified from their historical presentation to discontinued operations on the Consolidated Statement of Income, for all periods presented. The gains or losses associated with these divested businesses are recorded in discontinued operations on the Consolidated Statement of Income. Additionally, segment information does not include the operating results of businesses classified as discontinued operations for all periods presented. Management does not expect any continuing involvement with these businesses following their divestiture, and these businesses are expected to be disposed of within one year.

Concentration of credit and business risks - We are exposed to credit risk in the event of nonpayment by customers, principally in the oil and gas, fire service, construction, utilities, chemicals and mining industries. Changes in these industries may significantly affect our financial performance and management's estimates. We mitigate our exposure to credit risk by performing ongoing credit evaluations and, when deemed necessary, requiring letters of credit, credit insurance, prepayments, guarantees or other collateral. No individual customer represented more than 10% of our sales.

Reclassifications - Certain reclassifications of prior years' data have been made to conform to the current year presentation.

Recently Adopted and Recently Issued Accounting Standards—In April 2014, the FASB issued ASU 2014-08, Reporting Discontinued Operations and Disclosures of Disposals of an Entity. This ASU amends the definition of a discontinued operation to include a disposal of a component or group of components that is disposed of or is classified as held for sale and represents a strategic shift that has (or will have) a major effect on an entity's operations and financial results. This ASU was adopted on January 1, 2015. The adoption of this ASU may have a material effect on our consolidated financial statements in the event that we were to divest of a component that meets the definition of discontinued operations.

47

In May 2014, the FASB issued ASU 2014-09, Revenue with Contracts from Customers. This ASU establishes a single revenue recognition model for all contracts with customers based on recognizing revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services, eliminates industry specific requirements, and expands disclosure requirements. This ASU is required to be adopted beginning January 1, 2018. Our revenue streams include agreements with distributors, agreements with end users and agreements with governmental entities. The Company continues to evaluate the impact that the adoption of this ASU will have on the consolidated financial statements, including the timing of revenue recognition associated with certain customized products. We have conducted a risk assessment and have worked with outside consultants to develop a transition plan that will enable us to meet the implementation requirement. We are currently in the process of reviewing and analyzing contracts. We anticipate using the modified retrospective method of adoption and having enhanced disclosures surrounding revenue recognition.

In June 2014, the FASB issued ASU 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could be Achieved after the Requisite Service Period.

Prior year balances in Note 11 were also adjusted to conform with current year presentation.

In April 2015, the FASB issued ASU 2015-04, Retirement Benefits - Practical Expedient for the Measurement Date of an Employer's Defined Benefit Obligation and Plan Assets. This ASU allows entities with a fiscal year end that does not coincide with a month end to use the closest month end for measurement purposes. This ASU also allows entities that have a significant event in an interim period that calls for a remeasurement of defined benefit plan assets and obligations to use the month end date that is closest to the date of the significant event. This ASU was adopted on January 1, 2016. The adoption of this ASU did not have a material effect on our consolidated financial statements.

In January 2017, the FASB issued ASU 2017-01, Business Combinations - Clarifying the Definition of a Business. This ASU provides further guidance for identifying whether a set of assets and activities is a business by providing a screen outlining that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This ASU is effective beginning in 2018 and will be applied prospectively. The adoption of this ASU may have a material effect on our consolidated financial statements in the event that we have an acquisition or disposal that falls within this screen.

In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment. This ASU simplifies the accounting for goodwill impairments under Step 2 by eliminating the requirement to perform procedures to determine the fair value of the assets and liabilities of the reporting unit, including previously unrecognized assets and liabilities, in order to determine the fair value of the goodwill and any impairment charge to be recognized. Under this ASU, the impairment charge to be recognized should be the amount by which the reporting unit's carrying value exceeds the reporting unit's fair value as calculated under Step 1 provided that the loss recognized should not exceed the total amount of goodwill allocated to the reporting unit. This ASU is effective beginning in 2019 for public entities and early adoption is permitted for interim or annual goodwill impairment tests performed after January 1, 2017. The adoption of this ASU may have a material effect on our consolidated financial statements in the event that we determine that goodwill for any of our reporting units is impaired.

Note 2—Restructuring Charges

During the years ended December 31, 2016, 2015 and 2014, we recorded restructuring charges, net of adjustments, of $5.7 million, $12.3 million, and $8.5 million, respectively. These charges were primarily related to reorganization activities.

In September 2016, certain employees in the Americas segment were offered a voluntary retirement incentive package (“VRIP”). The election window for participation closed on October 17, 2016. The employees were required to render service through January 31, 2017 to receive the VRIP and had until February 6, 2017 to revoke their election. None of the 83 employees who accepted the VRIP revoked their election to retire under the terms of the plan.  Non-cash special termination benefit expense of approximately $11.5 million is expected to be incurred in the first quarter of 2017 related to these elections. All benefits will be paid from our over funded North America pension plan.

During the year ended December 31, 2016, we recorded restructuring charges, net of adjustments, of $5.7 million. International segment charges of $5.3 million during the year ended December 31, 2016 were related to severance costs for staff reductions associated with ongoing initiatives to right size our operations in Europe and Japan. Americas segment restructuring charges of $1.8 million during the year ended December 31, 2016 related primarily to severance from staff reductions in Brazil and North America. Corporate segment charges were $0.2 million during the year ended December 31, 2016. Favorable adjustments for changes in estimates on employee restructuring reserves of $1.6 million were recorded during the year ended December 31, 2016.

Headcount was reduced by 179 in 2016. Headcount was reduced by 103 in the Americas segment, 75 in the International segment, and 1 in the Corporate segment.

For the year ended December 31, 2015, International segment charges of $7.4 million were primarily related to staff reductions in Europe, Australia, Japan, and China and a one-time benefit for employees impacted by our European Principal Operating Company. Americas charges of $3.3 million and Corporate segment charges of $1.6 million were primarily related to staff reductions in North America.

Headcount was reduced by 216 in 2015. Headcount was reduced by 70 in the Americas segment, 134 in the International segment, and 12 in the Corporate segment.

For the year ended December 31, 2014, International segment charges of $8.0 million were primarily related to severance from staff reductions in Europe, South Africa, and Australia as the Company continued to focus manufacturing efforts in line with our core products and to respond to changing economic conditions.

Activity and reserve balances for restructuring charges by segment were as follows:

(in millions)	Americas			International			Corporate			Total
Reserve balances at January 1, 2014	$	—		$	1.7		$	—		$	1.7
Restructuring charges	0.5			8.0			—			8.5

Note 3—Inventories

The following table sets forth the components of inventory:

	December 31,
(In thousands)	2016			2015
Finished products	$	54,348		$	74,929
Work in process	6,542			8,979
Raw materials and supplies	84,069			85,643
Inventories at current cost	144,959			169,551
Less: LIFO valuation	(41,893		)	(43,702		)
Total inventories	$	103,066		$	125,849

Inventories stated on the LIFO basis represent 25% and 23% of total inventories at December 31, 2016 and 2015, respectively.

Reductions in certain inventory quantities during the years ended December 31, 2016 and 2015 resulted in liquidations of LIFO inventories carried at lower costs prevailing in prior years. The effect of LIFO liquidations during 2016 reduced cost of sales by $0.3 million and increased net income by $0.2 million. The effect of LIFO liquidations during 2015 reduced cost of sales by $1.4 million and increased net income by $0.9 million.
