CustomersOur 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.through distribution. In our International segment, sales are made through both indirect and direct sales channels. For the year ended December 31, 2016,2018, no individual customer represented more than 10% of our sales.
Sales and DistributionOur 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, Casco Industries, Sonepar, BunzlWitmer Public Safety Group, Ten-8 Fire Equipment, Essendant 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 4,0003,200 authorized distributor locations worldwide. No individual distributor accounts for more than 10% of our sales.
CompetitionThe 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 equipmentPPE 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 equipmentPPE 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 and after-market service support and price.support.
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 DevelopmentTo 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 strategystrategies 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-geographiccross-geographical 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.

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-settingstandards-setting bodies, investment in research and development and our unique new product development process, we believe we are well-positionedwell 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 PropertyWe 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 SuppliersMany of the components of our products are formulated, machined, tooled or molded in-house from raw materials, which comprise approximately two thirdstwo-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 electronic components, rubber, high density polyethylene, chemical filter media, eye and face protective lenses, air cylinders, certain metals electronic components and ballistic resistant, flame 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, 20162018 for further information on our conflict minerals analysis. Form SD may be obtained free of charge at www.sec.gov.
AssociatesAt December 31, 2016,2018, we employed approximately 4,3004,800 associates, of which approximately 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 MattersOur 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.
SeasonalityOur 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 relatedGovernment-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.

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 materiallymaterial 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 adversenegative publicity against us could have a materiallymaterial 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.
Our subsidiary, Mine Safety Appliances Company, LLC, 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 material adverse effect on our business, operating results, financial condition and liquidity.
Our subsidiary, Mine Safety Appliances Company, LLC (“MSA LLC”) was named as a defendant in 1,481 cumulative trauma lawsuits comprised of 2,355 claims at December 31, 2018. Cumulative trauma product liability claims involve exposures to harmful substances (e.g., silica, asbestos and coal dust) that occurred 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. A reserve has been established with respect to cumulative trauma product liability claims currently asserted and estimated incurred but not reported (“IBNR”) cumulative trauma product liability claims. Because our cumulative trauma product liability risk is subject to inherent uncertainties, including unfavorable trial rulings or developments, an increase in newly filed claims, or more aggressive settlement demands, and since MSA LLC is largely self-insured, there can be no certainty that MSA LLC may not ultimately incur losses in excess of presently recorded liabilities. These losses could have a material adverse effect on our business, operating results, financial condition and liquidity. We will adjust the reserve relating to cumulative trauma product liability claims from time to time based on whether the actual numbers, types, and settlement values of claims asserted differ from current projections and estimates or there are significant changes in the facts underlying the assumptions used in establishing the reserve. These adjustments may be material and could materially impact future periods in which the reserve is adjusted.
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 $71.7 million and notes receivable of $59.6 million at December 31, 2018. 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 now largely self-insured for cumulative trauma product liability claims. As a result, additional amounts recorded as insurance receivables will be limited and based on calculating the amounts to be reimbursed pursuant to negotiated Coverage-in-Place Agreements. Various factors could affect the timing and amount of recovery of the insurance receivables, including: assumptions regarding claims composition (which are relevant to calculating reimbursement under the terms of certain Coverage-in-Place Agreements) 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 MSA LLC being unable to recover for amounts already paid to resolve claims (and recorded as insurance receivables) and could have a material adverse effect on our business, operating results, financial condition and liquidity.
Going forward, most of MSA LLC's cumulative trauma product liability costs will be expensed without the expectation of insurance reimbursement. MSA LLC expects to obtain some limited insurance reimbursement from negotiated Coverage-in-Place Agreements (although that coverage may not be immediately triggered or accessible) or from other sources of coverage, but the precise amount of insurance reimbursement that may be available cannot be determined with specificity at this time.

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 have significant operations in a number of countries outside the U.S., including some in emerging markets. Long-term economic uncertainty in some of the regions of the world in which we are currently seeing a slowdown in China, recessionary conditions in Braziloperate, such as Asia, Latin America, the Middle East 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 conditionsEurope, 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 backpullback 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 backpullback 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 could result in declines in our consolidated results of operations and financial condition.cash flow.
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 affectresult in declines in our net sales, earningsconsolidated results of operations and cash flow.
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 July 31, 2017, we completed the acquisition of Globe Holding Company, LLC ("Globe"), which is a leading innovator and provider of firefighter protective clothing and boots. Please refer to Note 13 of the consolidated financial statements in Part II Item 8 of this Form 10-K for further details. Any future acquisitions will depend on our ability to marketidentify suitable acquisition candidates and sellsuccessfully consummate such acquisitions. Acquisitions involve a number of risks including:
failure of the acquired businesses to achieve the results we expect;
diversion of our productsmanagement’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 Globe, or may acquire in the future, we may not realize anticipated cost savings, improved manufacturing efficiencies and increased revenue, which may result in material 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.

Our plans to continue to improve productivity and reduce complexity may not be successful, which could adversely affect our ability to compete.
MSA has integrated parts of its European operating segment that have historically been individually managed entities, into a centrally managed organization model. 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.
Our plans to improve future profitability through restructuring programs may not be successful and could lead to unintended consequences.
We have incurred and may incur restructuring charges primarily related to severance costs for staff reductions associated with our ongoing initiatives to drive profitable growth and right size our operations. For example in 2016, certain employees in the Americas segment were offered a voluntary retirement incentive package (“VRIP”). Non-cash special termination benefit expense of approximately $11.4 million was recorded in the first quarter of 2017 related to elections under the VRIP. Our cost structure in future periods is somewhat dependent upon our ability to maintain increased productivity without backfilling certain positions. If our programs are not successful, there could be a material adverse effect on our business and consolidated results of operations.
Our future results are subject to existing government regulationsthe risk that purchased components and standards. Changesmaterials are unavailable or available at excessive cost due to material shortages, excessive demand, currency fluctuation, inflationary pressure and other factors.
We depend on various components and materials to manufacture our products. Although we have not experienced any substantial difficulty in such regulationsobtaining components and standardsmaterials, 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 material adverse effect on our business, results of operations and financial condition. Our inability to successfully manage price fluctuations due to market demand, currency risks or material shortages, or future price fluctuations could have a material adverse effect on our business and our consolidated results of operations and financial condition.
A failure to comply with themof our information systems or a cybersecurity breach could materially and adversely affect our business, results of operations.operations and financial condition.
MostThe proper functioning and security of our information systems is critical to the operation and reputation 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, cyber-criminals and other persons could attempt to gain unauthorized access to our information systems with the intent of harming our company, harming our information systems 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, or if there is any compromise or breach of our security, it could result in a violation of applicable privacy and other laws, legal and financial exposure, remediation costs, negative impacts on our customers' willingness to transact business with us, or a loss of confidence in our security measures, which could have an adverse effect on our business, our reputation and our consolidated results of operations and financial condition.
Like many companies, from time to time, we have experienced attacks on our computer systems by unauthorized outside parties. Because the techniques used by computer hackers and others to access or sabotage networks continually 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, the impact of any future incident cannot be predicted, including the failure of our information systems or misappropriation of our technologies and/or processes. Any such system failure or 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 also maintain a robust cyber response plan, including an assessment of triggers for internal and external reporting of cyber incidents. We expect to continue devoting substantial 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 disruption to our information systems.

If we fail to introduce successful new products or extend our existing product lines, we could lose our market position and our financial performance could 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 material 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 requiredsubject to meet performancethe risks inherent in the development process. These risks include delays, the failure of new products and test standards designedproduct line extensions to protectachieve anticipated levels of market acceptance and the safetyrisk of peoplefailed product introductions.
If we lose any of our key personnel or are unable to attract, train and/or retain qualified personnel or plan the succession of senior management, our ability to manage our business and infrastructures aroundcontinue our growth could be negatively impacted.
Our success depends in large part on the world.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 inabilitysuccess also depends on the abilities of new personnel to comply with these standardsfunction 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.

In addition, hiring, training, and successfully integrating replacement critical personnel could be time consuming, may cause additional disruptions to our operations, and may be unsuccessful, which could negatively impact future revenues. Competition for personnel is intense, and we cannot assure you that we will be successful in attracting and retaining qualified personnel. The hiring of new personnel may also result in increased costs and we do not currently maintain key person life insurance.

Our success also depends on effective succession planning. Failure to ensure effective transfer of knowledge and smooth transitions involving senior management could hinder our strategic planning and execution. From time to time, senior management or other key employees may leave our company. While we strive to reduce the negative impact of such changes, the loss of any key employee could result in significant disruptions to our operations, including adversely affecting the timeliness of product releases, the successful implementation and completion of company initiatives, the effectiveness of our disclosure controls and procedures and our internal control over financial reporting, and the results of our operations.

We are subject to various federal, state and local laws and regulations across our global organization and any violation of these laws and regulations could adversely affect our results of operations.
We are subject to extensivenumerous, and sometimes conflicting, laws and regulations on matters as diverse as anticorruption, import/export controls, product content requirements, trade restrictions, tariffs, taxation, sanctions, internal and disclosure control obligations, securities regulation, from U.S. federal, state,anti-competition, data privacy and local governments, as well aslabor relations, among others.

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 materiallymaterial adverse effect on our business, consolidated results of operations.operations and financial condition.

We benefit from free trade laws and regulations, such as the North American Free TradeUnited States-Mexico-Canada 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 TradeUnited States-Mexico-Canada Agreement (“USMCA”), provide certain beneficial duties and tariffs for qualifying imports and exports, subject to compliance with the applicable classification and other requirements.

We are subject to various U.S and foreign tax laws and any changes in these laws related to the taxation of businesses and resolutions of tax disputes 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.project which could adversely impact our effective tax rate.

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.

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 adversenegative publicity or other issues, including concerns about product safety or quality, real or perceived, could negatively impact our business which could have a materiallymaterial adverse effect on our business, operating results and financial condition.
A failure of our information systems could materially and adversely affect our business,consolidated results of operations and financial condition.

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.

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 2016,2018, approximately half of our net sales were made by operations located outside the United States. Our internationalThose operations are subject to various political, economic and other risks and uncertainties, which could adversely affecthave a material adverse effect on 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'sCompany'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;
foreign privacy laws and regulations;
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 U.S. Foreign Corrupt Practices ActAct;
difficulty in hiring and retaining qualified employees;
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.operations; and
risks associated with the United Kingdom's decision to exit the European Union, including disruptions to trade and free movement of goods, services and people to and from the United Kingdom; increased foreign exchange volatility with respect to the British pound; and additional legal and economic uncertainty.
Any one or more of these risks could have a negative impact on the success of our international operations and, thereby, materially and adversely affecthave a material adverse effect 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.

Because we derive a significant portion of our sales from the operations of our foreign subsidiaries, future currency exchange rate fluctuations maycould adversely affect our results of operations and financial condition, and maycould affect the comparability of our results between financial periods.
For the year ended December 31, 2016,In 2018, 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 of the affiliate 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. A weakening of the currencies in which sales are generated relative to the currencies in which costs are denominated would decrease our results of operations and cash flow. Although the Company uses instruments to hedge certain foreign currency risks, these hedges only offset a portion of the Company’s exposure to foreign currency fluctuations.
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 ableOur inability to effectively manage our exchange rate risks or that any volatility in currency exchange rates will notcould have a materiallymaterial adverse effect on our business, 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.

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 unableOur inability to maintain the proprietary nature of our technologies could have a material adverse effect on our consolidated results of operations and financial condition couldcondition.
If our goodwill, other intangible assets and long-lived assets become impaired, we may be materiallyrequired to record significant charges to earnings.
We review our long-lived assets for impairment when events or changes in circumstances indicate the carrying amount may not be recoverable. Goodwill and adversely affected.
indefinite-lived intangible assets are required to be assessed for impairment at least annually. Factors that may be considered a change in circumstances, indicating that the carrying amount of our goodwill, indefinite-lived intangible assets or long-lived assets may not be recoverable, include slower growth rates in our markets, reduced expected future cash flows, increased country risk premiums as a result of political uncertainty and a decline in stock price and market capitalization. We consider available current information when calculating our impairment charge. If there are indicators of impairment, our long-term cash flow forecasts for our operations deteriorate or discount rates increase, we may be required to recognize additional 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 uselater periods. See Note 12 of the consolidated financial statements in Part II Item 8 of this Form 10-K for the carrying amounts of goodwill in each of our reporting segments and details on indefinite-lived intangible assets and divestitures may result in impairments to goodwill and other long-lived assets.

Risks related to our defined benefit pension and other post-retirement plans maycould adversely impactaffect 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 the consolidated financial statements in Part II Item 8 Financial Statements and Supplementary Data.of this Form 10-K.
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 Statementsconsolidated 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.covenants.

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.

Net sales for the Americas segment were $678.4$854.3 million for the year ended December 31, 2016, a decrease2018, an increase of $26.4$117.5 million, or 4%16%, compared to $704.8$736.8 million for the year ended December 31, 2015. Currency translation effects decreased2017. During 2018, constant currency sales in the Americas segment salesincreased 17% compared to 2017, driven primarily by 2%, reflecting weaker currencies across Latin America. Acquisitions, primarily Latchways,the acquisition of Globe, which increased sales in the Americas segment by 1%. In 2016,9% during the period. The 8% organic constant currency sales in the Americas segment decreased 3% compared to the prior year. This decreasegrowth during 2018, 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 offsetdriven by an improvement in portable gas detection as well as fire and rescue helmet sales.growth throughout our core product portfolio.
Net sales for the International segment were $471.1$503.8 million for the year ended December 31, 2016,2018, an increase of $45.1$43.8 million, or 11%10%, compared to $426.0$460.0 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 in2017. During the International segment by 10%. Organicyear ended December 31, 2018, constant currency sales in the International segment increased 3% in 2016,8% as we recognized stronger sales 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-corethroughout our product sales.portfolio.
Gross profit. Gross profit for the year ended December 31, 20162018 was $523.6$611.9 million, an increase of $22.5$73.0 million, or 4%14%, compared to $501.1$538.9 million for the year ended December 31, 2015.2017. The ratio of gross profit to net sales was 45.6%45.1% in 20162018 compared to 44.3%45.0% in 2015.2017. The slightly higher gross profit ratio is attributable to improved price realization and improved leverage on indirect costs, offset by inflationary pressures and dilution associated with a less favorable product mix from the Globe acquisition. The impact of the Globe acquisition reduced the gross profit percentage by 1% or 100 basis points.
Selling, general and administrative expenses. Selling, general and administrative ("SG&A") expenses were $324.8 million for the year ended December 31, 2018, an increase of $24.7 million, or 8%, compared to $300.1 million for the year ended December 31, 2017. The increase is related to increased SG&A expenses related to the Globe acquisition, higher variable compensation cost due to stronger revenue, profitability and cash flow performance as well as higher selling and marketing costs to invest resources in driving revenue growth. Selling, general and administrative expenses were 23.9% of net sales in 2018, compared to 25.1% of net sales in 2017.

Research and development expense. Research and development expense was $52.7 million for the year ended December 31, 2018, an increase of $2.6 million, or 5%, compared to $50.1 million for the year ended December 31, 2017. Research and development expense was 3.9% of net sales in 2018, compared to 4.2% of net sales in 2017. We continue to develop new products for global safety markets, including the newly unveiled M1 SCBA for which we began production at the end of 2018, as well as the V Series product family of fall protection for the industrial market. During 2018, we capitalized $1.6 million of software development costs. Please refer to Note 1—Significant Accounting Policies of the consolidated financial statements in Part II Item 8 of this Form 10-K for additional information.
Restructuring, net of adjustments. During the year ended December 31, 2018, the Company recorded restructuring charges of $13.2 million, primarily related to severance costs for staff reductions associated with our ongoing initiatives to drive profitable growth in Europe and the legal and operational realignment of our U.S. and Canadian operations. This compared to charges of $17.6 million during the year ended December 31, 2017, primarily related to non-cash special termination benefit expense of $11.4 million for the voluntary retirement incentive package elected by certain employees in the Americas segment and severance costs for staff reductions associated with our ongoing initiatives to drive profitable growth in Europe and right size our operations in Australia and Africa. We expect to make progress on our International segment footprint rationalization project in the first quarter of 2019. While these actions may drive noncash restructuring charges associated with the write-off of cumulative currency translation, we expect these actions to drive a more efficient business model and are similar to the steps we took to reduce our footprint and improve our efficiency in other areas of the International segment.
Currency exchange. Currency exchange losses were $2.3 million during the year ended December 31, 2018, compared to losses of $5.1 million during the year ended December 31, 2017. Currency exchange losses in both years were related to management of foreign currency exposure on unsettled intercompany balances. Refer to Note 17—Derivative Financial Instruments of the consolidated financial statements in Part II Item 8 of this Form 10-K for information regarding our currency exchange rate risk management strategy.
Other operating expense. Other operating expense during the year ended December 31, 2018 was $45.3 million and was primarily related to an increase in our reserve for cumulative trauma product liability claims. That increase resulted from the Company’s revision of its estimates of potential liability for cumulative trauma product liability claims as part of its annual review process. This compared to Other operating expense during the year ended December 31, 2017 of $126.4 million. In the fourth quarter of 2017, MSA LLC determined that a reasonable estimate of the liability for incurred but not reported ("IBNR") cumulative trauma liability claims was $111.1 million as of December 31, 2017. MSA LLC recorded a total charge of $126.4 million before tax ($85.0 million after tax) during 2017 representing the estimated liability in excess of available insurance coverage for both asserted and IBNR cumulative trauma product liability claims. Please refer to Note 19—Contingencies of the consolidated financial statements in Part II Item 8 of this Form 10-K for additional information.
GAAP operating income. Consolidated operating income for the year ended December 31, 2018 was $173.5 million compared to $39.6 million for the year ended December 31, 2017. The increase in operating results was primarily driven by higher sales volumes, lower restructuring and other operating expense, partially offset by higher SG&A costs.
Adjusted operating income. Americas adjusted operating income for the year ended December 31, 2018 was $206.8 million, an increase of $31.2 million, or 18%, compared to $175.6 million for the year ended December 31, 2017. The increase was primarily related to the higher level of sales partially offset by higher SG&A costs as a result of higher variable compensation cost due to stronger revenue performance, and higher selling and marketing costs to invest resources in driving revenue growth.
International adjusted operating income for the year ended December 31, 2018 was $59.9 million, an increase of $9.5 million, or 19%, compared to $50.4 million for the year ended December 31, 2017. The increase was primarily attributable to higher sales volumes and improvements associated with our ongoing initiatives to right size our operations in Europe.
Corporate segment adjusted operating loss for the year ended December 31, 2018 was $31.9 million, an improvement of $1.1 million, or 3%, compared to an operating loss of $33.0 million for the year ended December 31, 2017, reflecting lower legal expenses.

Total other expense, net. Other expense for the year ended December 31, 2018 was $11.1 million, an increase of $1.3 million, or 14%, compared to $9.8 million for the year ended December 31, 2017. The increase was related to higher interest expense and the loss on extinguishment of debt which were only partially offset by higher interest income.
Income taxes. The reported effective tax rate for the the year ended December 31, 2018, was 22.9%, which included a benefit of 1.6% for certain share-based payments related to the application of ASU 2016-09 09 as discussed in Note 1—Significant Accounting Policies of the consolidated financial statements in Part II Item 8 of this Form 10-K and a charge of 1.1% associated with to exit taxes related to our U.S., Canadian and European realignment. This compared to a reported effective tax rate of 9.5% for the year ended December 31, 2017, which included a benefit of 28.0% for certain share-based payments related to the adoption of ASU 2016-09 and a benefit of 8.4% associated with the reduction of exit taxes related to our European reorganization. The remaining effective tax rate change was primarily due to the decrease in the U.S. federal statutory rate and benefits associated with the foreign provisions of U.S. tax reform, partially offset by the increased profitability in less favorable tax jurisdictions, higher entity losses in jurisdictions where we cannot take tax benefits and reduced manufacturing deduction benefits.
    During 2018, the Company recorded $1.8 million of foreign income tax reserves related to the legal and operational realignment of our U.S., Canadian and European operations.     
On December 22, 2017, SAB 118 was issued to address the application of U.S. GAAP in situations when a registrant does not have the necessary information available, prepared or analyzed in reasonable detail to complete the accounting for certain income tax effects of the Act. In accordance with SAB 118, the Company calculated its best estimate of the impact of the Act and recorded income tax expense of $19.8 million during the fourth quarter of 2017. At December 31, 2018, the Company has now completed its accounting for all of the enactment-date income tax effects of the Act. Accordingly, we reduced our estimate for the one-time transition tax by $2.0 million and increased our estimate for the revaluation of U.S. deferred tax assets and liabilities by $2.5 million and a $2.0 million increase associated with prepaid taxes for updated regulations related to the Act.

Net sales for the Americas segment were $736.8 million for the year ended December 31, 2017, an increase of $58.4 million, or 9%, compared to $678.4 million for the year ended December 31, 2016. During 2017, constant currency sales in the Americas segment increased 8% compared to the prior year period, driven primarily by the acquisition of Globe on July 31, 2017, which provided a 7% increase in sales. We also saw growth in head protection and fall protection on improving conditions in industrial markets. These increases were partially offset by a lower level of shipments of self-contained breathing apparatus ("SCBA"). At December 31, 2017, we entered 2018 with a strong pipeline of business secured in the fire service market as the fourth quarter order book for SCBA reflected our highest incoming order total of this entire replacement cycle.
Net sales for the International segment were $460.0 million for the year ended December 31, 2017, a decrease of $11.1 million, or 2%, compared to $471.1 million for the year ended December 31, 2016. Constant currency sales in the International segment decreased 4% during 2017, primarily due to a lower volume of non-core military helmet sales in Europe as well as less breathing apparatus, fall protection, and portable instruments sales across the segment. These decreases were partially offset by a higher volume of FGFD sales in the Middle East and head protection across the segment.
Gross profit. Gross profit for the year ended December 31, 2017, was $538.9 million, an increase of $16.6 million, or 3%, compared to $522.2 million for the year ended December 31, 2016. The ratio of gross profit to net sales was 45.0% in 2017 compared to 45.4% in 2016. The slightly lower gross profit ratio during 2017 is primarily attributable to lower product margins from our Globe acquisition mostly offset by improved margins onacross many of our G1 SCBA associated with our value engineering initiatives and improvements in our warranty expense and inventory and obsolescence expense.core products.

Restructuring and other charges. During the year ended December 31, 2016,2017, the Company recorded restructuring charges net of adjustments,$17.6 million, primarily related to the voluntary retirement incentive package discussed below as well as to severance costs for staff reductions associated with our ongoing initiatives to drive profitable growth in Europe and right size our operations in Australia and Africa. This compared to charges of $5.7 million during the year ended December 31, 2016, primarily related to severance costs for staff reductions associated with ongoing initiatives to right size our operations in Europe, Brazil, and Japan.

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$11.4 million is expected to be recordedwas incurred in the first quarter of 2017 related to these elections. All benefits will bewere 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 $5.1 million during the year ended December 31, 2017, compared to $0.8 million during the year ended December 31, 2016, compared to $2.2 million during the year ended December 31, 2015.2016.

Total other expense, net. Other expense for the year ended December 31, 20162017, was $12.3$9.8 million, an increase of $0.6$1.0 million, or 5%12%, compared to $11.7$8.8 million for the year ended December 31, 2015. The increase reflects higher interest expense associated with the Latchways and Senscient acquisitions.2016.
Income taxes. The reported effective tax rate for the year ended December 31, 2017, was 9.5%, which included a benefit of 28.0% for certain share-based payments related to the adoption of ASU 2016-09 as discussed in Note 1—Significant Accounting Policies of the consolidated financial statements in Part II Item 8 of this Form 10-K and a benefit of 8.4% associated with the reduction of exit taxes related to our European reorganization as well as benefits related to higher profitability in more favorable tax jurisdictions and additional manufacturing deduction benefits. The unfavorable effects of U.S. tax reform partially offset these benefits. The reported 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 4.3% associated with exit taxes related to our European reorganizationreorganization. The remaining effective tax rate change was primarily due to additional manufacturing deduction benefits and the release of 4.3% compareda valuation allowance on foreign losses.

On December 22, 2017, SAB 118 was issued to address the application of US GAAP in situations when a registrant does not have the necessary information available, prepared or analyzed in reasonable detail to complete the accounting for certain income tax effects of the sameAct. In accordance with SAB 118, the Company calculated its best estimate of the impact of the Act and recorded income tax expense of $19.8 million during the fourth quarter of 2017, the period last year.in which the legislation was enacted. Of this amount, $18.0 million related to the one-time transition tax and the remaining $1.8 million related to the revaluation of U.S. deferred tax assets and liabilities. In addition, deferred taxes have been recorded on the outside basis differences of non-U.S. subsidiaries in the amount of $7.8 million, fully offset by foreign tax credits. Changes to applicable tax law, regulations or interpretations of the Act may require further adjustments and changes in our estimates.
MSAThe Company finalized its European reorganization during 2016. The reorganization iswas 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 year ended December 31, 2017, the Company incurred $6.5had a benefit due to the reduction of $2.5 million of charges associated with exit taxes related to our European reorganization, compared to $7.7expense of $6.5 million for the year ended December 31, 2016.
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. We early adopted this ASU on January 1, 2017 using the modified retrospective approach which resulted in 2015.a $6.2 million cumulative-effect adjustment directly to retained earnings during the year ended December 31, 2017, for any previously deferred income tax effects.
In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, which we adopted effective January 1, 2017. From an income tax perspective, this ASU requires that all excess tax benefits and deficiencies that pertain to share-based payment arrangements be recognized as a component of income tax expense rather than as a component of additional paid-in-capital. We expect this to create volatility in the effective tax rate on a go-forward basis as the impact is treated as a discrete item within our quarterly tax provision. The adoption of this standard resulted in an $8.3 million tax benefit during the year ended December 31, 2017.
Please refer to Note 1—Significant Accounting Policies of the consolidated financial statements in Part II Item 8 of this Form 10-K for additional information regarding the two standards adopted.

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.

Non-GAAP Financial Information
We may provide information regarding organic constant currency changes, financial measures excluding the impact of acquisitions and related strategic transaction costs, adjusted operating income, and adjusted operating margin percentage, 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 to7—Segment Information of the consolidated financial statements Inin Part II Item 8 of this Form 10-K.
We may also refer to certainprovide financial measuresinformation 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, 2016,2018, approximately 51%32% 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%2023. At December 31, 2018, approximately 79% of our borrowings are denominated in US dollars, which limits our exposure to currency exchange rate fluctuations.
At December 31, 2016,2018, we had cash, and cash equivalents and restricted cash totaling $113.8$140.6 million, of which $106.9 million was held by our foreign subsidiaries. The $106.9included $93.6 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 andsubsidiaries. Cash, cash equivalents domesticand restricted 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$2.7 million during the year ended December 31, 2016,2018, compared to an decreaseincrease of $0.1$22.9 million during 20152017 and an increase of $9.7$6.6 million during 2014.2016. During the year ended December 31, 2018, we repatriated $96 million of cash from our foreign affiliates. While cash repatriation allows us to tap into our offshore cash more efficiently, our business continues to generate strong cash flow, and this improvement in cash flow has enabled us to continue to fund our dividend and de-lever. In July 2018, we reached a settlement on the disputed portion of our insurance receivable as discussed in Note 19—Contingencies to the consolidated financial statements in Part II Item 8 of this Form 10-K. The settlement ensured collection of the full amount of the insurance receivable that was previously subject to litigation. Payment was received in the third quarter of 2018. We plan to continue to employ a balanced capital allocation strategy that prioritizes growth investments, funding our dividend and servicing debt obligations.
Our unsecured senior revolving credit facility provides for borrowings up to $575.0$600.0 million through 20202023 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%3.47% in 2016.2018. At December 31, 2016, $377.22018, $363.5 million of the $575.0$600.0 million senior revolving credit facility was unused, including letters of credit.

CUMULATIVE TRANSLATION ADJUSTMENTS
The year-end position of the U.S. dollar relative to international currencies resulted in a translation loss of $25.9$29.8 million being recorded to cumulative translation adjustments for the year ended December 31, 2016.2018. This compares to gains of $38.4 million in 2017 and losses of $47.7$25.9 million in 20152016. The translation loss in 2018 was primarily related to the strengthening of the U.S. dollar relative to the euro and $40.0 millionBritish pound. The translation gain in 2014.2017 was primarily related to the weakening of the U.S. dollar against the euro, British pound and Mexican peso. 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.

We expect to meet our 2017, 20182019 and 20192020 debt service obligations through cash provided by operations. Approximately $191.0$233.5 million of debt payable in 20202023 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 2020,2023, 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$4.8 million in 2019, $4.6$4.0 million in 2020, and $3.6$3.2 million in 2021.2021, $2.5 million in 2022, and $2.3 million in 2023.
The Company had outstanding bank guarantees and standby letters of credit with banks as of December 31, 20162018 totaling $13.1$11.4 million, of which $6.9$3.1 million 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, 2016.2018. The Company is also required to provide cash collateral in connection with certain arrangements. At December 31, 2016,2018, the Company has $1.2$0.5 million of restricted cash in support of these arrangements.
We expect to make net contributions of $5.9$7.1 million to our pension plans in 20172019 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.

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 11—Significant Accounting Policies to the Consolidated Financial Statementsconsolidated 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 productProduct liability losses of its subsidiary MSA LLC into two main categories:claims are categorized as either single incident andor cumulative trauma.

Table of Contents

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 LLCThe Company estimates its liability for single incident product liability claims based on expected settlement costs for reportedasserted single incident product liability 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 includesincurred but not 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.("IBNR"). 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 comprisedLLC's combined cumulative trauma product liability reserve consists 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 spendliability for asserted cumulative trauma product liability claims (inclusive of settlementsnot yet resolved 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.
IBNR cumulative trauma product liability claims. Management works with itsoutside legal counsel quarterly to review and assess MSA LLC's exposure to asserted cumulative trauma product liability claims not yet resolved. In addition, in connection with finalizing and reporting the Company's results of operations, management works annually (unless significant changes in trends or new developments warrant an earlier review) with an outside valuation consultant and outside legal counsel to review itsMSA LLC's exposure to asserted 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.claims not yet resolved and IBNR cumulative trauma product liability claims. The review process for asserted cumulative trauma product liability claims not yet resolved takes into account available facts for those claims including the number and composition of pendingsuch claims, outcomes of matters resolved during current and prior periods, and variances associated with different plaintiffs’groups of claims, plaintiffs' counsel, and venues, as well as any other information known aboutrelevant information. The review process for IBNR claims involves a number of key judgments and assumptions, including as to the current docket.
Cumulative trauma product liability litigation is inherently unpredictable. Factors that can limit our ability to estimate potential liability include the lacknumber and types of claims experience with applicable plaintiffs’ counsel, asthat may be asserted, the period in which claims experience can vary significantly among different counsel, low volume of resolution, lack of confidence withmay be asserted and resolved, the consistencypercentage 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 willmay be dismissed or otherwise resolved until latewithout payment, the average cost to resolve claims on which a payment is made, the manner in which MSA LLC will defend claims, and 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 lossmedical and legal environments that will be incurred. These actual loss amounts are highly variableapplicable to the assertion, evaluation, and turn on a case by case analysisresolution of claims in the relevant facts, including the nature of the injury, the jurisdiction in which the claim is filed, the plaintiffs' counselfuture.
Additional information respecting MSA LLC’s product liability claims and the number of partiesaccounting for such claims in the lawsuit. In addition, there are uncertainties concerning the impactCompany’s Consolidated Financial Statements, including estimated liabilities accrued on account of bankruptcies of other companies that are co-defendantssuch claims, is contained 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 subsequentNote 19—Contingencies to the Couch verdict. (Please refer to Note 19 Contingencies of the Consolidated Financial Statementsconsolidated financial statements in Part II Item 8 of this Form 10-K10-K.
Insurance receivable. In the normal course of business, the Company makes payments to settle product liability claims and for further details onrelated defense costs and records receivables for the Couch verdict.)
estimated amounts that are covered by insurance. Various factors could affect the timing and amount of recovery of the insurance receivable balances, including the terms of the settlement agreements reached with the insurers, assumptions regarding various aspects of the composition of future claims (which are relevant to calculating reimbursement under the terms of certain Coverage-In-Place Agreements), the financial ability of the insurance carriers to pay the claims, and the advice of MSA LLC's outside legal counsel. As a result, MSA LLC recorded ais now largely self-insured for costs associated with cumulative trauma product liability claims. Most 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. TheseLLC's cumulative trauma product liability costs are recognized as incurred.
As noted above,now expensed without the liability recorded does not take into account any IBNR claims and certainexpectation 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.

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.insurance reimbursement.
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$5.0 million and $5.2$4.6 million at December 31, 20162018 and 2015,2017, 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

The Tax Cuts and Jobs Act of 2017 (“the Act”), which was signed into law on December 22, 2017 has resulted in significant changes to the U.S. corporate income taxes have been provided on undistributed earningstax system. In accordance with SAB 118, the Company calculated its best estimate 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 taxesthe Act and foreignrecorded income tax creditsexpense of $19.8 million during the fourth quarter of 2017. At December 31, 2018, the Company has now completed its accounting for all of the enactment-date income tax effects of the Act. Accordingly, we reduced our estimate for the one-time transition tax by $2.0 million and increased our estimate for the revaluation of U.S. deferred tax assets and liabilities by $2.5 million and a $2.0 million increase associated with prepaid taxes.

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.Act.
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 for a majority of our U.S. and foreign plans were based on the spot rate method at December 31, 2018. The remaining plans' discount rate assumptions are based on published long-term bond indices or a company-specific yield curve model.
We recognize, as of a measurement date, any unrecognized actuarial net gains or losses that exceed 10% of the larger of the projected benefit obligations or the plan assets, defined as the "corridor." Amounts inside the corridor are amortized over the plan participants' life expectancy. Expected returns on plan assets are based on our historical returns by asset class.
Please refer to Note 14 to the Consolidated Financial Statementsconsolidated financial statements in Part II Item 8 of this Form 10-K for additional information on the spot rate method and further details on the funded status of our pension and post-retirement benefit plans.

Revenue Recognition. We generate revenue primarily from manufacturing and selling a comprehensive line of safety products to protect the health and safety of workers and facility infrastructures around the world in the oil, gas and petrochemical, fire service, construction, utilities and mining industries. Our core safety products include fixed gas and flame detection instruments, breathing apparatus where SCBA is the principal product, portable gas detection instruments, industrial head protection products, firefighter helmets & protective apparel and fall protection devices. Our customers generally fall into two categories: distributors and industrial or military end-users. In our Americas segment, approximately 75% to 85% of our sales are made through distributors. In our International segment, approximately 55% to 65% of our sales are made through distributors. The underlying principles of revenue recognition are identical for both categories of customers and revenue is generally recognized at a point in time as described below.
Revenue from the sale of products is recognized when title, ownershipthere is persuasive evidence of an arrangement and the risk of loss have transferredcontrol passes 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. Our payment terms vary by the type and location of our customer and the products offered. The term between invoicing and when payment is due is not significant.

Refer to Note 7—Segment Information to the consolidated financial statements in Part II Item 8 of this Form 10-K for disaggregation of revenue by segment and product group, as we believe this best depicts how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors.

Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services. Amounts billed and due from our customers are classified as receivables on the consolidated balance sheet. 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 contracts with customers, primarily distributor customers, receivehave an element of variable consideration that is estimated when revenue is recognized under the contract to the extent that it is material to the individual contract. Variable consideration includes volume incentive rebates, performance guarantees, price rebatesconcessions and returns. Rebates are based on theirachieving a certain level of purchases and other performance criteria that are documented in established distributor programs. These rebates are estimated based on projected sales to the customer and accrued as a reduction of net sales as they are earned by the customer. The rebate accrual is reviewed monthly and adjustments are made as the estimate of projected sales changes. Product returns, including an adjustment for restocking fees if it is material, are estimated based on historical return experience and revenue is adjusted. Sales, value add and other taxes collected with revenue-producing activities and remitted to governmental authorities are excluded from revenue.

Depending on the terms of the arrangement, we may defer revenue for which we have a future obligation, including training and extended warranty and technical services, until such time that the obligation has been satisfied. We use an observable price, or a cost plus margin approach when one is not available, to determine the stand-alone selling price for separate performance obligations. We have elected to recognize the cost for shipping and handling as an expense when control of the product has passed to the customer. These costs are included within the Cost of Products Sold line on the Consolidated Statement of Income. Amounts billed to customers for shipping and handling are included in net sales.

We typically receive interim milestone payments under certain contracts, including our fixed gas and flame detection projects, as work progresses. For some of these contracts, we may be entitled to receive an advance payment. Revenue for these contracts is generally recognized as control passes to the customer, which is a point in time upon shipment of the product, and if applicable, acceptance by the customer. We recognize a liability for these advance payments in excess of revenue recognized and present it as contract liabilities on the Consolidated Balance Sheet. The advance payment is typically not considered a significant financing component because it is used to meet working capital demands that can be higher in the early stages of a contract and to protect us from the other party failing to adequately complete some or all of its obligations under the contract. In some cases, the customer retains a small portion of the contract price, typically 10%, until completion of the contract, which we present as contract assets on the Consolidated Balance Sheet. Accordingly, during the period of contract performance, billings and costs are accumulated on the Consolidated Balance Sheet as contract assets or contract liabilities, but no income is recognized until completion of the project and control has passed to the customer. As of December 31, 2018, there were no material contract assets or contract liabilities recorded on the Consolidated Balance Sheet.

Practical Expedients and Exemptions

We do not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed.

We do not assess whether a contract has a significant financing component if the expectation at contract inception is such that the period between payment by the customer and the transfer of the promised goods or services to the customer will be one year or less.

We generally expense sales commissions when incurred because the amortization period would have been one year or less. These costs are recorded within selling, general and administrative expenses in our Condensed Consolidated Statement of Income.  
Goodwill.Goodwill and Indefinite-lived Intangible Assets. In the fourth quarterOn October 1st 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 2016,2018, we elected to bypass the qualitative evaluation for all of our reporting units and performed a two-step quantitative test at October 1, 2016.2018. 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 significantlymaterially and adversely impactaffect reported consolidated results of operations and shareholders’ equity. At October 1, 2016,2018, based on our quantitative test, the fair values of all of our reporting units exceeded their carrying value by at least 40%89%.
Foreign currency. As partIntangible assets with indefinite lives are also subject to impairment testing on October 1st of our currency exchange rate risk management strategy, we enter into certain derivative foreign currency forward contracts that do not meeteach year, or more frequently if indicators of impairment exist. The impairment test compares the U.S. GAAP criteria for hedge accounting, but which havefair value of the impactintangible assets with their carrying amounts. We performed a quantitative assessment of partially offsetting certain foreign currency exposures.the indefinite lived trade name intangible asset as outlined in ASC 350 by comparing the estimated fair value of the trade name intangible asset to its carrying value.

This ASU clarifies when entities should account for fees paid in a cloud computing arrangement as a software license or service contract. This ASU was adopted on January 1, 2016 and was implemented on a prospective basis. The adoption of this ASU did not have a material effect on our consolidated financial statements.
In July 2015, the FASB issued ASU 2015-11, Simplifying the Measurement of Inventory. This ASU requires inventory to be measured at the lower of cost and net realizable value. This ASU applies to inventory measured using the first-in, first-out (FIFO) or average cost methods only. This ASU will be effective beginning in 2017. The adoption of this ASU is not expected to have a material effect on our consolidated financial statements.
In July 2015, the FASB issued ASU 2015-12, Plan Accounting: Defined Benefit Pension Plans (Topic 960), Defined Contribution Pension Plans (Topic 962), Health and Welfare Benefit Plans (Topic 965).

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 adjustmentsin Part II Item 8 of this Form 10-K for business combinations are identified.further information on our updated revenue recognition policy.
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 inJanuary 1, 2019. The Company has developed a transition plan and continues to evaluate the impact that the adoption of this ASU 2016-02 will have on the consolidated financial statements. During 2017, we conducted a survey to identify all leases across the organization and are currently working to obtain all lease contracts to accumulate the necessary information for adoption. We identified that a majority of our leases fall into one of three categories: office equipment, real estate and vehicles. We also identified that most office equipment and vehicle leases utilize standard master leasing contracts that have similar terms. During 2018, we selected a service provider to help us inventory and account for our leases and gathered the majority of the data necessary to prepare the transition accounting. We are finalizing the data upload to the system and accumulating information for leases entered into at the end of 2018. We estimate that total assets and total liabilities will increase within the range of $52 million and $58 million on January 1, 2019 when the ASU is adopted. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, Leases. ASU 2018-10 includes certain clarifications to address potential narrow-scope implementation issues which the Company is incorporating into its assessment and adoption of ASU 2016-02. Additionally, in July 2018, the FASB issued ASU 2018-11, Targeted Improvements to Topic 842, Leases. ASU 2018-11 which provides an additional transition method to adopt ASU 2016-02 identified as comparative reporting at adoption. We expect to use this new transition approach and the comparative periods presented in our consolidated financial statements will continue to be reported in accordance with ASC 840, Leases. We anticipate that we will elect the package of practical expedients allowed in the standard, which among other things, allows us to carry forward our historical lease classification. All of our leases have historically been classified as operating leases. We also anticipate that we will make an accounting policy election to use the practical expedient allowed in the standard to not separate lease and non-lease components for new leases entered into after January 1, 2019 when calculating the lease liability under ASU 2016-02.
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 inwas adopted on January 1, 2017. The provisions of this ASU which impacted us included a requirement that all excess tax benefits and deficiencies that pertain to share-based payment arrangements be recognized as a component of income tax expense rather than as a component of shareholders’ equity. The Company is currently evaluatingexpects this to create volatility in its effective tax rate on a go-forward basis as the impact thatis treated as a discrete item within our quarterly tax provision. The extent of excess tax benefits/deficiencies is subject to variation in our stock price and timing/extent of stock-based compensation share vestings and employee stock option exercises. This ASU also removes the adoptionimpact of the excess tax benefits and deficiencies from the calculation of diluted earnings per share and no longer requires a presentation of excess tax benefits and deficiencies related to the vesting and exercise of share-based compensation as both an operating outflow and financing inflow on the statement of cash flows. We have applied all of these changes on a prospective basis and therefore, prior years were not adjusted. Additionally, this ASU allows for an accounting policy election to estimate the number of awards that are expected to vest or account for forfeitures when they occur. We elected to maintain our current forfeitures policy and will have on the consolidated financial statements.continue to include an estimate of those forfeitures when recognizing stock-based compensation expense. This ASU also requires cash payments to tax authorities when an employer uses a net-settlement feature to withhold shares to meet statutory tax withholding provisions to be presented as a financing activity (eliminating previous diversity in practice). Adoption of this ASU resulted in an additional discrete tax benefit of approximately $2.5 million and $8.3 million during years ended December 31, 2018 and 2017, respectively.
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. TheBased on a review of its portfolio of financial instruments, the Company is currently evaluating the impact thatdoes not believe the adoption of thesethis ASU will have a material impact on the consolidated financial statements, and expects thatbut does expect the adoption willto result in increased disclosure.additional disclosures.

ThisWe adopted this ASU is effective beginningon January 1, 2018 using the retrospective method. The adoption of ASU 2016-18 had an impact on our financial statement presentation within the Consolidated Statement of Cash Flows, as amounts generally described as restricted cash and restricted cash equivalents are now 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 and transfers of these amounts between balance sheet line items are no longer presented as an operating, investing or financing cash flow. For the years ended December 31, 2017 and 2016, cash flow from financing activities increased by $2.5 million and cash flow used in 2018 to be adopted onfinancing activities increased by $1.5 million, respectively as a retrospective basis and early adoption is permitted.

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 Company will adopt ASU 2017-04 effective January 1, 2019 and 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.
In March 2017, the FASB issued ASU 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Post-retirement Benefit Cost, to improve the presentation of net periodic pension and net periodic post-retirement benefit cost. This ASU requires companies to present the service cost component of net periodic benefit cost in the same income statement line item as other compensation costs arising from services rendered during the period. Only the service cost component will be eligible for capitalization in assets. Additionally, this ASU requires that companies present the other components of the net periodic benefit cost separately from the line item that includes the service cost and outside of any subtotal of income from operations, if one is presented. This ASU is effective for annual periods beginning after December 15, 2017, and early adoption is permitted. The amendments in this ASU are to be applied retrospectively for presentation in the Consolidated Statement of Income and prospectively for the capitalization of the service cost component of net periodic pension cost and net periodic post-retirement benefit in assets. A practical expedient allows the Company to use the amount disclosed in its pension and other post-retirement benefit plan note for the prior comparative periods as the estimation basis for applying the retrospective presentation requirements. The Company adopted ASU 2017-07 on January 1, 2018, using the retrospective method and elected to use the practical expedient. The adoption of this ASU resulted in a $4.1 million, $3.8 million and $3.5 million decrease in operating income for the years ended December 31, 2018, 2017 and 2016, respectively. The Company does not capitalize costs in assets so there is no impact from that provision of ASU 2017-07.

In May 2017, the FASB issued ASU 2017-09, Stock Compensation - Scope of Modification Accounting, which amends the scope of modification accounting for share-based payment arrangements. This ASU provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting. Specifically, an entity would not apply modification accounting if the fair value, vesting conditions, and classification of the awards are the same immediately before and after the modification. This ASU is effective for periods beginning after December 31, 2017. The Company's adoption of ASU 2017-09 on January 1, 2018, did not have a material effect on our consolidated financial statements.
In January 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which gives entities the option to reclassify to retained earnings the tax effects resulting from the new tax reform legislation commonly known as the Tax Cuts and Jobs Act ("the Act") related to items in AOCI that the FASB refers to as having been stranded in AOCI. The new guidance may be applied retrospectively to each period in which the effect of the Act is recognized in the period of adoption. The Company must adopt this guidance for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted for periods for which financial statements have not yet been issued or made available for issuance, including the period the Act was enacted. The guidance, when adopted, will require new disclosures regarding a company’s accounting policy for releasing the tax effects in AOCI and permit a company the option to reclassify to retained earnings the tax effects resulting from the Act that are stranded in AOCI. The Company will adopt ASU 2018-02 effective January 1, 2019 and this adoption will result in a reclassification between retained earnings and AOCI. The Company estimates that the impact from ASU 2018-02 will increase retained earnings by approximately $4.0 million, with an offsetting increase to accumulated other comprehensive loss for the same amount.
In August 2018, the FASB issued ASU 2018-13, Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement, which improves fair value disclosure requirements by removing disclosures that are not cost beneficial, clarifying disclosures’ specific requirements and adding relevant disclosure requirements. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. Early adoption is permitted and an entity can choose to early adopt any removed or modified disclosures upon issuance of this ASU and delay adoption of the additional disclosures until their effective date. The Company is still evaluating the impact that the adoption of ASU 2018-13 will have on the consolidated financial statements and has not yet decided whether to early adopt the amendments.
In August 2018, the FASB issued ASU 2018-14, Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans, which improves defined benefit disclosure requirements by removing disclosures that are not cost beneficial, clarifying disclosures’ specific requirements and adding relevant disclosure requirements. This ASU is effective for fiscal years ending after December 15, 2020 and early adoption is permitted.  The amendments in this ASU are required to be applied on a retrospective basis to all periods presented.

In August 2018, the FASB issued ASU 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract, which will now allow all cloud computing arrangements classified as service contracts to capitalize certain implementation costs in accordance with ASC 350-40, Intangibles - Goodwill and Other - Internal-Use Software, depending on the project stage within which the costs were incurred. This ASU is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal periods. Early adoption of the amendments in this ASU is permitted, including adoption in any interim period and the amendments can be applied either retrospectively or prospectively. The Company has adopted this ASU prospectively for all implementation costs incurred related to cloud computing arrangements and the implementation did not have a material impact on our consolidated financial statements.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk
Market risk represents the risk of adverse changes in the value of a financial instrument caused by changes in currency exchange rates, interest rates and equity prices. We are exposed to market risks related to currency exchange rates and interest rates.
Currency exchange 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, 20162018 by approximately $53.5$63.6 million and $6.1$6.4 million, or 4.7% and 6.6%5.1%, 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, 2016,2018, we had open foreign currency forward contracts with a U.S. dollar notional value of $75.3$72.4 million. A hypothetical 10% increase in December 31, 20162018 forward exchange rates would result in a $7.5$7.2 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, 2016,2018, we had $201.2 million$129.8 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$11.0 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, 2016,2018, we had $191.0$233.4 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.

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, 2016.2018. 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, 2016.2018.

Definition and Limitations of Internal Control Over Financial Reporting

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.

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. Other highly liquid investments consist of $11.4 million in money market funds that are valued at net asset value (“NAV”). The money market funds are required to price and transact at a NAV per share that fluctuates based upon the pricing of the underlying portfolio of securities and this requirement may impact the value of those fund shares.
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$0.5 million and $2.4$3.6 million at December 31, 20162018 and December 31, 2015,2017, respectively. These balances were used to support letter of credit balances.
Inventories—Inventories are stated at the lower of cost or market.net realizable value. The majority of U.S. inventories are valued on the last-in, first-out (LIFO) cost method.method which is used since this method provides better matching of costs and revenues. Other inventories are valued on the average cost method orat actual costs, at standard costs which approximate actual costs.costs or in very rare occasions, on the average cost method. It is the Company’sCompany's general policy to write-down any inventory that is identified as obsolete andobsolete. Additionally, it will write-down any inventory that has aged or has not movedbalance in more thanexcess of the last twenty-four months.months of consumption.

Investment securitiesThe Company’s investment securities, primarily fixed income, are classified as available for sale. The securities are recorded at fair market value and reported in “Investments, short-term” in the accompanying Consolidated Balance Sheet with changes in fair market value recorded in other comprehensive income, net of tax. The purchases and sales of these investments are classified as investing activities in the Consolidated Statement of Cash Flows.
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, 2018, 2017 and 2016 2015 and 2014 was $27.0 million, $26.9 million, $28.0 million and $26.2$27.0 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.

Software Development Costs—Software development costs consist primarily of costs incurred in software development and related personnel compensation to create, enhance and deploy the Company’s broad range of wireless technology and cloud-based computing safety services. Software development costs, other than software development costs qualifying for capitalization, are expensed as incurred. Costs of computer software developed or obtained for internal use that are incurred in the preliminary project and post implementation stages are expensed as incurred. Certain costs incurred during the application and development stage, which primarily include compensation and related expenses, are capitalized. Additionally, costs of upgrades and enhancements are capitalized when it is probable that the upgrades and enhancements will result in added functionality. The estimated useful life of costs capitalized is three years. Capitalized costs are amortized using the straight-line method over the estimated useful life, beginning in the period in which the software is ready for its intended use or when the upgrade or enhancement is deployed. During 2018, there was approximately $1.6 million of software development costs capitalized. During 2017, there was no software development costs capitalized.
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 on October 1st or whenever circumstances change such that the recorded value of the asset may not be recoverable. We performed a quantitative assessment of the indefinite lived trade name intangible asset as outlined in ASC 350 by comparing the estimated fair value of the trade name intangible asset to their carrying value. We estimate the fair value using the relief from royalty income approach. A number of significant assumptions and estimates are involved in the application of the relief from royalty model, including sales volumes and prices, royalty rates and tax rates. Forecasts are based on sales generated by the underlying trade name assets and are generally based on approved business unit operating plans for the early years and historical relationships in later years. Based on this assessment, there was no indication of impairment for 2018.
Goodwill is not amortized, but is subject to impairment assessments. In the fourth quarterOn October 1st of each year, or more frequently if indicators of impairment exist or if a decision is made to sell a business, we evaluate goodwill and indefinite lived intangible assets 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 2016,2018, we elected to bypass the qualitative evaluation for all of our reporting units, and performed a two-step quantitative test at October 1, 2016.2018. 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 businessreporting 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 significantlymaterially and adversely impactaffect reported consolidated results of operations and shareholders’ equity. There has been no impairment of our goodwill as of December 31, 2016, 20152018, 2017 or 2014.2016.

Revenue Recognition—We generate revenue primarily from manufacturing and selling a comprehensive line of safety products to protect the health and safety of workers and facility infrastructures around the world in the oil, gas and petrochemical, fire service, construction, utilities and mining industries. Our core safety products include fixed gas and flame detection instruments, breathing apparatus where SCBA is the principal product, portable gas detection instruments, industrial head protection products, firefighter helmets & protective apparel and fall protection devices. Our customers generally fall into two categories: distributors and industrial or military end-users. In our Americas segment, approximately 75% to 85% of our sales are made through distributors. In our International segment, approximately 55% to 65% of our sales are made through distributors. The underlying principles of revenue recognition are identical for both categories of customers and revenue is generally recognized at a point in time as described below.
We account for revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers, which we adopted on January 1, 2018, using the modified retrospective method. Revenue from the sale of products is recognized when title, ownershipthere is persuasive evidence of an arrangement and the risk of loss have transferredcontrol passes 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. Our payment terms vary by the type and location of our customer and the products offered. The term between invoicing and when payment is due is not significant.
Revenue is measured as the amount of consideration we expect to receive in exchange for transferring goods or providing services. Amounts billed and due from our customers are classified as receivables on the consolidated balance sheet. 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 contracts with customers, primarily distributor customers, receivehave an element of variable consideration that is estimated when revenue is recognized under the contract to the extent that it is material to the individual contract. Variable consideration includes volume incentive rebates, performance guarantees, price rebatesconcessions and returns. Rebates are based on theirachieving a certain level of purchases and other performance criteria that are documented in established distributor programs. These rebates are estimated based on projected sales to the customer and accrued as a reduction of net sales as they are earned by the customer. The rebate accrual is reviewed monthly and adjustments are made as the estimate of projected sales changes. Product returns, including an adjustment for restocking fees if it is material, are estimated based on historical return experience and revenue is adjusted. Sales, value add and other taxes collected with revenue-producing activities and remitted to governmental authorities are excluded from revenue.
Shipping
Refer to Note 7—Segment Information for disaggregation of revenue by segment and Handling—Shippingproduct group, as we believe this best depicts how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors.

Depending on the terms of the arrangement, we may defer revenue for which we have a future obligation, including training and extended warranty and technical services, until such time that the obligation has been satisfied. We use an observable price, or a cost plus margin approach when one is not available, to determine the stand-alone selling price for separate performance obligations. We have elected to recognize the cost for shipping and handling expenses for products soldas an expense when control of the product has passed to customersthe customer. These costs are charged to costincluded within the Cost of products sold as incurred.Products Sold line on the Consolidated Statement of Income. Amounts billed to customers for shipping and handling are included in net sales.

We typically receive interim milestone payments under certain contracts, including our fixed gas and flame detection projects, as work progresses. For some of these contracts, we may be entitled to receive an advance payment. Revenue for these contracts is generally recognized as control passes to the customer, which is a point in time upon shipment of the product, and if applicable, acceptance by the customer. We recognize a liability for these advance payments in excess of revenue recognized and present it as contract liabilities on the Consolidated Balance Sheet. The advance payment is typically not considered a significant financing component because it is used to meet working capital demands that can be higher in the early stages of a contract and to protect us from the other party failing to adequately complete some or all of its obligations under the contract. In some cases, the customer retains a small portion of the contract price, typically 10%, until completion of the contract, which we present as contract assets on the Consolidated Balance Sheet. Accordingly, during the period of contract performance, billings and costs are accumulated on the Consolidated Balance Sheet as contract assets or contract liabilities, but no income is recognized until completion of the project and control has passed to the customer. As of December 31, 2018, there were no material contract assets or contract liabilities recorded on the Consolidated Balance Sheet.

Practical Expedients and Exemptions

We do not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed.

We do not assess whether a contract has a significant financing component if the expectation at contract inception is such that the period between payment by the customer and the transfer of the promised goods or services to the customer will be one year or less.

We generally expense sales commissions when incurred because the amortization period would have been one year or less. These costs are recorded within selling, general and administrative expenses in our Condensed Consolidated Statement of Income.  
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 providedrecognized 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 madeDeferred taxes are booked for possible U.S. taxes on the undistributedavailable cash in excess of working capital for non-U.S. subsidiaries as these earnings of foreign subsidiaries that are no longer considered to be reinvested indefinitely.permanently reinvested.

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 statementsstatement of income as currency exchange (income) losslosses, net in the current period.
Commitments and Contingencies—For asserted claims and assessments, liabilities are recorded when an unfavorable outcome of a matterloss is deemed to be probable and the amount of the loss is reasonably estimable. Management determinesassesses the likelihoodprobability of an unfavorable outcome with respect to asserted claims or assessments 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 deemedassessed to be probable, management weighsevaluates estimates of the probability of estimated losses,potential loss, and the most reasonable loss estimate is recorded.recorded (or, if the estimate of the loss is a range, and no amount within the range is considered to be a better estimate than any other amount, the minimum amount in the range is recorded). If an unfavorable outcome of a matterloss is deemed to be reasonably possible but less than probable and/or such loss cannot be reasonably estimated, then the matter is disclosed and no liability is recorded.
With respect to unasserted claims or assessments, management must first determinedetermines whether it is probable that a claim or assessment may be asserted and then, if so, the degree of probability that an assertion will be made is likely, then, a determination as to the likelihood of an unfavorable outcome. If an unfavorable outcome andis probable, management assesses whether the ability to reasonably estimate theamount of potential loss can be reasonably estimated and, if so, accrues the most reasonable estimate of the loss (or, if the estimate of the loss is made.a range, and not amount within the range is considered to be a better estimate than any other amount, the minimum amount in the range is recorded). If an unfavorable outcome is reasonably possible but less than probable, or the amount of loss cannot be reasonably estimated, then the matter is disclosed and no liability is recorded. 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 and/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, gas and gas,petrochemical, 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. These reclassifications relate to (1) additional captions disclosed within the operating section of the Consolidated Statement of Cash Flows but do not change the overall cash flow from operating activities for the prior years as previously reported, and (2) additional captions disclosed for product warranty activity within the table that reconciles the changes in the Company's accrued warranty reserve (Note 19).
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. ThisWe adopted 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 anticipate2014-09 using the modified retrospective method as 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. This ASU clarifies the accounting treatment for share based payment awards that contain performance targets. This ASU was adopted on January 1, 2016.2018. The majority of our revenue transactions consist of a single performance obligation to transfer promised goods or services. The adoption of this ASUnew standard did not have a materialimpact the Company's consolidated statement of income or balance sheet and there was no cumulative effect of initially applying the standard to the opening balance of retained earnings. See Revenue Recognition section above for further information on our consolidated financial statements.
In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements - Going Concern. This ASU clarifies management's responsibility to evaluate whether there is a substantial doubt about the entity's ability to continue as a going concern and provides guidance for related footnote disclosures. This ASU is effective for the annual period ending December 31, 2016. The adoption of this ASU did not have a material effect on our consolidated financial statements.
In January 2015, the FASB issued ASU 2015-01, Income Statement - Extraordinary and Unusual Items. This ASU eliminates the requirement to separately present and disclose extraordinary and unusual items in the financial statements. 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 February 2015, the FASB issued ASU 2015-02, Amendments to the Consolidation Analysis. This ASU changes the analysis that an entity must perform to determine whether it should consolidate certain types of legal entities. 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 April 2015, the FASB issued ASU 2015-03, Imputation of Interest - Simplifying the Presentation of Debt Issuance Costs. This ASU simplifies the presentation of debt issuance costs and requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability. In August 2015, the FASB issued ASU 2015-15, Imputation of Interest - Simplifying the Presentation of Debt Issuance Costs. This ASU simplifies the presentation of debt issuance costs for line of credit arrangements. These ASUs were adopted on January 1, 2016. The Consolidated Balance Sheet as of December 31, 2015 has been adjusted to apply the change in accounting principle retrospectively, which resulted in a decrease in Prepaid expenses and other current assets of $0.4 million, a decrease in Other noncurrent assets of $1.5 million, a decrease in the current portion of long-term debt, net of $17 thousand, and a decrease in long-term debt of $1.9 million as of December 31, 2015. There was no impact to the Statements of Consolidated Income as a result of the change in accounting principle. 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 April 2015, the FASB issued ASU 2015-05, Goodwill and Other Internal Use Software - Customer's Accounting for Fees Paid in a Cloud Computing Arrangement. This ASU clarifies when entities should account for fees paid in a cloud computing arrangement as a software license or service contract. This ASU was adopted on January 1, 2016 and was implemented on a prospective basis. The adoption of this ASU did not have a material effect on our consolidated financial statements.
In July 2015, the FASB issued ASU 2015-11, Simplifying the Measurement of Inventory. This ASU requires inventory to be measured at the lower of cost and net realizable value. This ASU applies to inventory measured using the first-in, first-out (FIFO) or average cost methods only. This ASU will be effective beginning in 2017. The adoption of this ASU is not expected to have a material effect on our consolidated financial statements.updated revenue recognition policy.

In July 2015, the FASB issued ASU 2015-12, Plan Accounting: Defined Benefit Pension Plans (Topic 960), Defined Contribution Pension Plans (Topic 962), Health and Welfare Benefit Plans (Topic 965). This ASU simplifies complexities within employee benefit plan accounting including Fully Benefit-Responsive Investment Contracts, Plan Investment Disclosures, and the Measurement Date Practical Expedient. 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 inJanuary 1, 2019. The Company has developed a transition plan and continues to evaluate the impact that the adoption of this ASU 2016-02 will have on the consolidated financial statements. During 2017, we conducted a survey to identify all leases across the organization and are currently working to obtain all lease contracts to accumulate the necessary information for adoption. We identified that a majority of our leases fall into one of three categories: office equipment, real estate and vehicles. We also identified that most office equipment and vehicle leases utilize standard master leasing contracts that have similar terms. During 2018, we selected a service provider to help us inventory and account for our leases and gathered the majority of the data necessary to prepare the transition accounting. We are finalizing the data upload to the system and accumulating information for leases entered into at the end of 2018. We estimate that total assets and total liabilities will increase within the range of $52 million and $58 million on January 1, 2019 when the ASU is adopted. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, Leases. ASU 2018-10 includes certain clarifications to address potential narrow-scope implementation issues which the Company is incorporating into its assessment and adoption of ASU 2016-02. Additionally, in July 2018, the FASB issued ASU 2018-11, Targeted Improvements to Topic 842, Leases. ASU 2018-11 which provides an additional transition method to adopt ASU 2016-02 identified as comparative reporting at adoption. We expect to use this new transition approach and the comparative periods presented in our consolidated financial statements will continue to be reported in accordance with ASC 840, Leases. We anticipate that we will elect the package of practical expedients allowed in the standard, which among other things, allows us to carry forward our historical lease classification. All of our leases have historically been classified as operating leases. We also anticipate that we will make an accounting policy election to use the practical expedient allowed in the standard to not separate lease and non-lease components for new leases entered into after January 1, 2019 when calculating the lease liability under ASU 2016-02.
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 inwas adopted on January 1, 2017. The provisions of this ASU which impacted us included a requirement that all excess tax benefits and deficiencies that pertain to share-based payment arrangements be recognized as a component of income tax expense rather than as a component of shareholders’ equity. The Company is currently evaluatingexpects this to create volatility in its effective tax rate on a go-forward basis as the impact thatis treated as a discrete item within our quarterly tax provision. The extent of excess tax benefits/deficiencies is subject to variation in our stock price and timing/extent of stock-based compensation share vestings and employee stock option exercises. This ASU also removes the adoptionimpact of the excess tax benefits and deficiencies from the calculation of diluted earnings per share and no longer requires a presentation of excess tax benefits and deficiencies related to the vesting and exercise of share-based compensation as both an operating outflow and financing inflow on the statement of cash flows. We have applied all of these changes on a prospective basis and therefore, prior years were not adjusted. Additionally, this ASU allows for an accounting policy election to estimate the number of awards that are expected to vest or account for forfeitures when they occur. We elected to maintain our current forfeitures policy and will have on the consolidated financial statements.continue to include an estimate of those forfeitures when recognizing stock-based compensation expense. This ASU also requires cash payments to tax authorities when an employer uses a net-settlement feature to withhold shares to meet statutory tax withholding provisions to be presented as a financing activity (eliminating previous diversity in practice). Adoption of this ASU resulted in an additional discrete tax benefit of approximately $2.5 million and $8.3 million during years ended December 31, 2018 and 2017, respectively.
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. TheBased on a review of its portfolio of financial instruments, the Company is currently evaluating the impact thatdoes not believe the adoption of thesethis ASU will have a material impact on the consolidated financial statements, and expects thatbut does expect the adoption willto result in increased disclosure.additional disclosures.
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 theCompany's adoption of thesethis ASU willon January 1, 2018 did not have a material impact on our presentation of the consolidated financial statements.statement of cash flows.
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 bewas early adopted on aJanuary 1, 2017 using the modified retrospective basis throughapproach which resulted in a cumulative-effect$6.2 million cumulative-effective adjustment directly to retained earnings and early adoption is permitted. The Company is currently evaluatingfor any previously deferred income tax effects during the impact that the adoptionyear ended December 31, 2017.

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. ThisWe adopted this ASU is effective beginningon January 1, 2018 using the retrospective method. The adoption of ASU 2016-18 had an impact on our financial statement presentation within the Consolidated Statement of Cash Flows, as amounts generally described as restricted cash and restricted cash equivalents are now 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 and transfers of these amounts between balance sheet line items are no longer presented as an operating, investing or financing cash flow. For the years ended December 31, 2017 and 2016, cash flow from financing activities increased by $2.5 million and cash flow used in 2018 to be adopted onfinancing activities increased by $1.5 million, respectively as a retrospective basis and early adoption is permitted. The Company is currently evaluating the impact thatresult of the adoption of thesethis ASU. Furthermore, adoption of ASU will have on the consolidated financial statements.2016-18 resulted in additional disclosures.
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 effectivewas adopted beginning in 2018 and will bewas 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 Company will adopt ASU 2017-04 effective January 1, 2019 and 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.
In March 2017, the FASB issued ASU 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Post-retirement Benefit Cost, to improve the presentation of net periodic pension and net periodic post-retirement benefit cost. This ASU requires companies to present the service cost component of net periodic benefit cost in the same income statement line item as other compensation costs arising from services rendered during the period. Only the service cost component will be eligible for capitalization in assets. Additionally, this ASU requires that companies present the other components of the net periodic benefit cost separately from the line item that includes the service cost and outside of any subtotal of income from operations, if one is presented. This ASU is effective for annual periods beginning after December 15, 2017, and early adoption is permitted. The amendments in this ASU are to be applied retrospectively for presentation in the Consolidated Statement of Income and prospectively for the capitalization of the service cost component of net periodic pension cost and net periodic post-retirement benefit in assets. A practical expedient allows the Company to use the amount disclosed in its pension and other post-retirement benefit plan note for the prior comparative periods as the estimation basis for applying the retrospective presentation requirements. The Company adopted ASU 2017-07 on January 1, 2018, using the retrospective method and elected to use the practical expedient. The adoption of this ASU resulted in a $4.1 million, $3.8 million and $3.5 million decrease in operating income for the years ended December 31, 2018, 2017 and 2016, respectively. The Company does not capitalize costs in assets so there is no impact from that provision of ASU 2017-07.
In May 2017, the FASB issued ASU 2017-09, Stock Compensation - Scope of Modification Accounting, which amends the scope of modification accounting for share-based payment arrangements. This ASU provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting. Specifically, an entity would not apply modification accounting if the fair value, vesting conditions, and classification of the awards are the same immediately before and after the modification. This ASU is effective for periods beginning after December 31, 2017. The Company's adoption of ASU 2017-09 on January 1, 2018, did not have a material effect on our consolidated financial statements.

In January 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which gives entities the option to reclassify to retained earnings the tax effects resulting from the new tax reform legislation commonly known as the Tax Cuts and Jobs Act ("the Act") related to items in AOCI that the FASB refers to as having been stranded in AOCI. The new guidance may be applied retrospectively to each period in which the effect of the Act is recognized in the period of adoption. The Company must adopt this guidance for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted for periods for which financial statements have not yet been issued or made available for issuance, including the period the Act was enacted. The guidance, when adopted, will require new disclosures regarding a company’s accounting policy for releasing the tax effects in AOCI and permit a company the option to reclassify to retained earnings the tax effects resulting from the Act that are stranded in AOCI. The Company will adopt ASU 2018-02 effective January 1, 2019 and this adoption will result in a reclassification between retained earnings and AOCI. The Company estimates that the impact from ASU 2018-02 will increase retained earnings by approximately $4.0 million, with an offsetting increase to accumulated other comprehensive loss for the same amount.
In August 2018, the FASB issued ASU 2018-13, Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement, which improves fair value disclosure requirements by removing disclosures that are not cost beneficial, clarifying disclosures’ specific requirements and adding relevant disclosure requirements. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. Early adoption is permitted and an entity can choose to early adopt any removed or modified disclosures upon issuance of this ASU and delay adoption of the additional disclosures until their effective date. The Company is still evaluating the impact that the adoption of ASU 2018-13 will have on the consolidated financial statements and has not yet decided whether to early adopt the amendments.
In August 2018, the FASB issued ASU 2018-14, Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans, which improves defined benefit disclosure requirements by removing disclosures that are not cost beneficial, clarifying disclosures’ specific requirements and adding relevant disclosure requirements. This ASU is effective for fiscal years ending after December 15, 2020 and early adoption is permitted.  The amendments in this ASU are required to be applied on a retrospective basis to all periods presented. The Company is still evaluating the impact that the adoption of ASU 2018-14 will have on the consolidated financial statements and has not yet decided whether to early adopt the amendments.
In August 2018, the FASB issued ASU 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement that is a Service Contract, which will now allow all cloud computing arrangements classified as service contracts to capitalize certain implementation costs in accordance with ASC 350-40, Intangibles - Goodwill and Other - Internal-Use Software, depending on the project stage within which the costs were incurred. This ASU is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal periods. Early adoption of the amendments in this ASU is permitted, including adoption in any interim period and the amendments can be applied either retrospectively or prospectively. The Company has adopted this ASU prospectively for all implementation costs incurred related to cloud computing arrangements and the implementation did not have a material impact on our consolidated financial statements.

The Mine Safety Appliances Company Stock Compensation Trust was established to provide shares for certain benefit plans, including the management and non-employee directors’ equity incentive plans. Shares held by the Stock Compensation Trust, and the corresponding cost of those shares, are reported as a reduction of common shares issued. Differences between the cost of the shares held by the Stock Compensation Trust and the market value of shares released for stock-related benefits are reflected in common stock issued. The Company began issuing Treasury Shares for all Board of Director share based benefit plans in April 2014.- The Company subsequently began issuing Treasury Shares for all share based benefit plans when theCompany's stock compensation trust was depleted in September 2014. Shares are issued from Treasury at the average Treasury Share cost on the date of the transaction.
On May 12, 2015, the Board of Directors adopted a new stock repurchase program replacing the existing program. The new program authorizes up to $100$100.0 million to repurchase MSA common stock in the open market and in private transactions. The share purchaserepurchase program has no expiration date. The maximum number of shares that may be purchased is calculated based on the dollars remaining under the program and the respective month-end closing share price. We repurchased 150,000 shares during 2015. There were no168,941 shares repurchased during 2017. No shares were repurchased during 2018 or 2016.

Note 7—Segment Information
We are organized into six geographic operating segments based on management responsibilities. The operating segments have been aggregated (based on economic similarities, the nature of their products, end-user markets and methods of distribution) into three reportable segments: Americas, International and Corporate.
The Americas and International 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 in 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.
The Company's sales are allocated to each country based primarily on the destination of the end-customer.
Adjusted operating income (loss) and adjusted operating margin are the measures used by the chief operating decision maker to evaluate segment performance and allocate resources. Adjusted operating income (loss) is defined as operating income from continuing operations excluding restructuring charges, and currency exchange gains (losses)., other operating expense and strategic transaction costs. Adjusted operating margin is defined as adjusted operating income (loss) divided by segment sales to external customers. Adjusted operating income (loss) and adjusted operating margin are not recognized terms under U.S. GAAP, and therefore, do not purport to be alternatives to operating income or operating margin from continuing operations as a measure of operating performance. Further, the Company's measure of adjusted operating income (loss) and adjusted operating margin may not be comparable to similarly titled measures of other companies. Adjusted operating income (loss) on a consolidated basis is presented in the following table to reconcile the segment operating performance measure to operating income as presented on the Consolidated Statement of Income.
The accounting principles applied at the operating segment level in determining operating income (loss) are generally the same as those applied at the consolidated financial statement level. Sales and transfers between operating segments are accounted for at market-based transaction prices and are eliminated in consolidation.
Reportable segment information is presented in the following table:

Note 8—Earnings per Share
Basic earnings per share is computed by dividing net income, after the deduction of preferred stock dividends and undistributed earnings allocated to participating securities, by the weighted average number of common shares outstanding during the period. Diluted earnings per share assumes the issuance of common stock for all potentially dilutive share equivalents outstanding not classified as participating securities. Participating securities are defined as unvested stock-based payment awards that contain nonforfeitable rights to dividends.

*The components of income before income taxes and the provision for income taxes relate to continuing operations.

The Company elected to treat Global Intangible Low Taxed Income (“GILTI”), which was effective in 2018 for the Company, as a period cost.
The Tax Cuts and Jobs Act of 2017 ("the Act"), which was signed into law on December 22, 2017, has resulted in significant changes to the U.S. corporate income tax system including reducing the U.S. corporate rate to 21% starting in 2018. The Act also creates a territorial tax system with a one-time mandatory tax on previously deferred foreign earnings of U.S. subsidiaries.
On December 22, 2017, SAB 118 was issued to address the application of US GAAP in situations when a registrant does not have the necessary information available, prepared or analyzed in reasonable detail to complete the accounting for certain income tax effects of the Act. In accordance with SAB 118, the Company calculated its best estimate of the impact of the Act and recorded income tax expense of $19.8 million during the fourth quarter of 2017, the period in which the legislation was enacted. Of this amount, $18.0 million related to the one-time transition tax and the remaining $1.8 million was related to the revaluation of U.S. deferred tax assets and liabilities. The company previously considered the earnings in non-U.S. subsidiaries to be indefinitely reinvested and, accordingly, recorded no deferred income taxes. As as result of the Act, among other things, the Company determined it will repatriate earnings for all non-U.S. subsidiaries with cash in excess of working capital needs. The Company has estimated the associated tax to be $1.9 million, offset partially by $0.7 million of foreign tax credits. At December 31, 2018, the Company has now completed its accounting for all of the enactment-date income tax effects of the Act. Accordingly, we reduced our estimate for the one-time transition tax by $2.0 million and increased our estimate for the revaluation of U.S. deferred tax assets and liabilities by $2.5 million and a $2.0 million increase associated with prepaid taxes for updated regulations related to the Act.
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 2016,2017, the Company incurred $6.5recognized a benefit of $2.5 million of charges associated with the reduction of exit taxes related to our European reorganization compared to $7.7incurring charges of $6.5 million in 2015.2016 related to the European reorganization.
During 2018, the Company recorded $1.8 million of foreign income tax reserves related to the legal and operational realignment of our U.S., Canadian and European operations.     
Included in discontinued operations is tax expense of $0.3 million in 2016, $0.6 million in 2015 and $0.6 million in 2014.
Cash flows from2016. There were no discontinued operations in the Consolidated Statement2018 or 2017.

At December 31, 2016,2018, we had net operating loss carryforwards of approximately $37.2$29.5 million, all of which are in non-U.S. tax jurisdictions. NetAll net operating loss carryforwards without a valuation allowance of $0.1 million will expire in 2017. The remainder either have a valuation allowance or may be carried forward for a period of at least six years. The change in valuation allowance for the year of $0.2$0.5 million is primarily due to our inability to recognize deferred tax assets on certain foreign entities that continue to generate losses partially offset by the release of a valuation allowance on certain losses.
No deferred U.S. income taxes have been provided on undistributed earnings

Table 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.Contents

A reconciliation of the change in the tax liability for unrecognized tax benefits for the years ended December 31, 20162018 and 20152017 is as follows:

We recognize interest related to unrecognized tax benefits in interest expense and penalties in operating expenses. Our liability for accrued interest and penalties related to uncertain tax positions was $0.9$3.3 million and $2.2 million at December 31, 2015. During 2016, we increased interest related to uncertain tax positions by $0.6 million. Our liability for accrued interest2018 and penalties related to uncertain tax positions was $1.5 million at December 31, 2016.2017, respectively.
We file a U.S. federal income tax return along with various state and foreign income tax returns. Examinations of our U.S. federal returns have been completed through 2013, with the 20122014 tax year closed by statute. Various state and foreign income tax returns may be subject to tax audits for periods after 2010.
Note 10—Stock Plans
The 2016 Management Equity Incentive Plan provides for various forms of stock-based compensation for eligible key employees through May 2026. Management stock-based compensation includes stock options, restricted stock, restricted stock units and performance stock units. The 20082017 Non-Employee Directors’ Equity Incentive Plan provides for grants of stock options and restricted stock to non-employee directors through May 2018.2027. Stock options are granted at market prices and expire after ten years. Stock options are exercisable beginning three years after the grant date. Restricted stock and restricted stock units are granted without payment to the Company and generally vest three years after the grant date. Restricted stock and restricted stock units are valued at the market value of the stock on the grant date. Performance stock units with a market condition are valued at an estimated fair value using the Monte Carlo model. The final number of shares to be issued for performance stock units may range from zero to 200% of the target award based on achieving the specified performance targets over the performance period. In general, unvested stock options, restricted stock and performance stock units are forfeited if the participant’s employment with the Company terminates for any reason other than retirement, death or disability. We issue Treasury shares for stock option exercises and grants of restricted stock and performance stock. Please refer to Note 6 for further information regarding stock compensation share issuance. As of December 31, 2016,2018, there were 1,368,6381,054,730 and 139,657114,878 shares, respectively, reserved for future grants under the management and non-employee directors’ equity incentive plans.

Stock option expense is based on the fair value of stock option grants estimated on the grant dates using the Black-Scholes option pricing model and the following weighted average assumptions for options granted in 2016, 20152016. There were no stock options granted in 2018 and 2014.2017.

Note 13—Acquisitions

Acquisition of Globe Holding Company, LLC
On July 31, 2017, we acquired 100% of the common stock in Globe Holding Company, LLC ("Globe") in an all-cash transaction valued at $215 million plus a working capital adjustment of $1.4 million. There is no contingent consideration.
Based in Pittsfield, NH, Globe is a leading innovator and provider of firefighter protective clothing and boots. This acquisition aligns with our corporate strategy in that it strengthens our leading position in the North American fire service market. The transaction was funded through borrowings on our unsecured senior revolving credit facility.
Globe operating results are included in our consolidated financial statements from the acquisition date as part of the Americas reportable segment. The acquisition qualifies as a business combination and was accounted for using the acquisition method of accounting.
We finalized the purchase price allocation as of June 30, 2018. The following table summarizes the fair values of the Globe assets acquired and liabilities assumed at the date of acquisition:
(In millions)July 31, 2017
Current assets (including cash of $58 thousand)$28.6

Trade name60.0
Distributor relationships40.2
Acquired technology and other intangible assets10.5
Goodwill74.5
Total assets acquired222.1
Total liabilities assumed5.7
Net assets acquired$216.4
Assets acquired and liabilities assumed in connection with the acquisition have been recorded at their fair values. Fair values were determined by management, based, in part on an independent valuation performed by a third party valuation specialist. The valuation methods used to determine the fair value of intangible assets included the relief from royalty method for trade name and technology related intangible assets; the excess earnings approach for distributor relationships using distributor inputs and contributory charges; and the cost method for assembled workforce which is included in goodwill. A number of significant assumptions and estimates were involved in the application of these valuation methods, including sales volumes and prices, royalty rates, costs to produce, tax rates, capital spending, discount rates, and working capital changes. Cash flow forecasts were generally based on Globe pre-acquisition forecasts coupled with estimated MSA sales synergies.

Table of Contents

Identifiable intangible assets with finite lives are subject to amortization over their estimated useful lives. The distributor relationships acquired in the Globe transaction will be amortized over a period of 20 years and the remaining identifiable assets will be amortized over 5 years. The trade name was determined to have an indefinite useful life. We will perform an impairment assessment annually on October 1st on the trade name, or sooner if there is a triggering event. Additionally, as part of each impairment assessment, we will reassess whether the asset continues to have an indefinite life or whether it should be reassessed with a finite life. Estimated future amortization expense related to the identifiable intangible assets is approximately $4.1 million in each of the next three years, $3.2 million in year four, and $2.0 million in year five. Estimated future depreciation expense related to Globe property, plant and equipment is approximately $1.0 million in each of the next five years.

Acquisition of Senscient, Inc.
On September 19, 2016, we acquired 100% of the common stock of Senscient, Inc. ("Senscient") for $19.1 million in cash. There is no contingent consideration. 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. The acquisition was funded through borrowings on our unsecured senior revolving credit facility.

Acquisition of Latchways
On October 21, 2015, MSA Safety Incorporated acquired Latchways plc and its affiliated companies, Latchways Australia Pty Limited ("LA"), Latchways Inc. ("LI"), HCL Group Plc ("HCL"), Height Solutions Limited ("HSL"), and Sigma 6 d.o.o. ('Sigma 6"), collectively referred to as ("Latchways"), for $190.9 million. There is no contingent consideration.
The acquisition was funded through cash on hand and borrowings on our $125.0 million unsecured senior revolving credit facility.
Latchways is a global provider of innovative fall protection systems based in the United Kingdom. Latchways solutions are found throughout the aerospace, power transmission, utility and telecommunication sectors, and Latchways products are integrated with major roofing and tower systems. In addition to providing us with greater access to the fall protection market, we believe that the acquisition significantly enhances our long-term corporate strategy in fall protection by providing us with world-class research and development talent and an industry-leading product line. While Latchways products will be sold globally, its operations will most significantly impact our International reportable segment.

Assets acquired and liabilities assumed in connection with both acquisitions have been recorded at their fair values. Fair values were determined by management, based, in part on an independent valuation performed by a third party valuation specialist. The valuation methods used to determine the fair value of intangible assets included the excess earnings approach for all customer relationships and Latchways technology related intangible assets; the relief from royalty method for the Latchways trade name and Senscient technology related intangible assets; and the cost method for assembled workforce which is included in goodwill for both acquisitions. A number of significant assumptions and estimates were involved in the application of these valuation methods, including sales volumes and prices, costs to produce, tax rates, capital spending, discount rates, and working capital changes. Cash flow forecasts were generally based on Latchways and Senscient pre-acquisition forecasts coupled with estimated MSA sales synergies. Identifiable intangible assets with finite lives are subject to amortization over their estimated useful lives. The identifiable intangible assets acquired in the Latchways transaction will be amortized over an estimated amortization period of 15 years. The identifiable intangible assets for Senscient include technology and customer-related intangibles which will be amortized over ten and five years, respectively. Estimated future amortization expense related to Latchways and Senscient identifiable intangible assets is approximately $4.5 million and $0.7 million respectively, in each of the next five years. A step up to fair value of acquired inventory of $1.6 million was recorded as part of the Latchways purchase price allocation. Amortization expense for inventory step up was $1.4years one and two, $0.5 million in 2016year three and the remaining $0.2 million is expected to be amortized in 2017. Estimated future depreciation expense related to Latchways property, plantyears four and equipment is approximately $0.9 million in each of the next five years.five.
Goodwill is calculated as the excess of the purchase price over the fair value of net assets acquired and represents the future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. Among the factors that contributed to a purchase price in excess of the fair value of the net tangible and intangible assets acquired were the acquisition of an assembled workforce, the expected synergies and other benefits that we believe will result from combining the operations of Globe, Latchways and Senscient with our operations. Goodwill of $74.5 million related to the LatchwaysGlobe acquisition has been recorded in ourthe Americas reportable segments as follows: $96.6 million in the International segment and $1.4 million in the Americas segment. Goodwill for Latchways is not expected to be tax deductible. Goodwill of $10.5 million related to the Senscient acquisition is includedwas recorded in the International operatingreportable segment and is deductibleexpected to be tax deductible.

Our results for the year ended December 31, 2015 include Latchways sales and net loss of $10.1 million and ($0.7) million, respectively.
The following unaudited pro forma information presents our combined results as if both acquisitions had occurred at the beginning of 2015.2016. The unaudited pro forma financial information was prepared to give effect to events that are (1) directly attributable to the acquisition; (2) factually supportable; and (3) expected to have a continuing impact on the combined company’s results. There were no material transactions between MSA and either LatchwaysSenscient or SenscientGlobe during the periods presented that are required to be eliminated. Intercompany transactions between LatchwaysSenscient companies as well as Senscientand Globe companies during the periods presented have been eliminated in the unaudited pro forma condensed combined financial information. The unaudited pro forma financial information does not reflect any cost savings, operating synergies or revenue enhancements that the combined companies may achieve as a result of the acquisitions or the costs to integrate the operations or the costs necessary to achieve cost savings, operating synergies or revenue enhancements.

Note 14—Pensions and Other Post-retirement Benefits
We maintain various defined benefit and defined contribution plans covering the majority of our employees. Our principal U.S. plan is funded in compliance with the Employee Retirement Income Security Act (ERISA). It is our general policy to fund current costs for the international plans, except in Germany and Mexico, where it is common practice and permissible under tax laws to accrue book reserves.
We provide health care benefits and limited life insurance for certain retired employees who are covered by our principal U.S. defined benefit pension plan until they become Medicare-eligible.

Effective December 31, 2017, the Company changed the method it uses to estimate the service and interest cost components of net periodic benefit cost for pension and other post-retirement benefits for a majority of its U.S. and foreign plans. Historically, the service and interest cost components for these plans were estimated using a single weighted-average discount rate derived from the yield curve used to measure the projected benefit obligation at the beginning of the period. The Company has elected to utilize a spot rate approach, which discounts the individual plan specific expected cash flows underlying the service and interest cost using the applicable spot rates derived from a yield curve used in the determination of the benefit obligation to the relevant projected cash flows. The Company made this change to improve the correlation between projected benefit cash flows and the corresponding yield curve spot rates and to provide a more precise measurement of service and interest costs. This change does not affect the measurement of total benefit obligations. Service and interest cost for the pension and OPEB plans were reduced by an estimated $1.8 million in 2018 as a result of this change. The Company has accounted for this change to the spot rate approach as a change in accounting estimate that is inseparable from a change in accounting principle, pursuant to Accounting Standards Codification (ASC) 250, Accounting Changes and Error Corrections, and accordingly, has accounted for it prospectively. For plans where the discount rate is not derived from plan specific expected cash flows, the Company will continue to employ the current approaches for measuring both the projected benefit obligations and the service and interest cost components of net periodic benefit cost for pension and other post-retirement benefits.
We recognize, as of a measurement date, any unrecognized actuarial net gains andor losses that exceed 10% of the larger of the projected benefit obligations or the plan assets, defined as the "corridor." Amounts inside the corridor are amortized over the average future working lifetime of the active population in the plan using the projected unit credit method. This approximates 11 years.participants' life expectancy.

Discount rates for a majority of our U.S. and foreign plans were determined using the aforementioned spot rate methodology for 2018 and 2017. All remaining plans' discount rates were determined using various corporate bond indexes as indicators of interest rate levels and movements and by matching our projected benefit obligation payment stream to current yields on high quality bonds.
The expected return on assets for the 20162018 net periodic pension cost was determined by multiplying the expected returns of each asset class (based on historical returns) by the expected percentage of the total portfolio invested in that asset class. A total return was determined by summing the expected returns over all asset classes.

The overall objective of our pension investment strategy is to earn a rate of return over time to satisfy the benefit obligations of the pension plans and to maintain sufficient liquidity to pay benefits and meet other cash requirements of our pension funds. Investment policies for our primary U.S. pension plan are determined by the plan’s Investment Committee and set forth in the plan’s investment policy. Asset managers are granted discretion for determining sector mix, selecting securities and timing transactions, subject to the guidelines of the investment policy. An aggressive, flexible management of the portfolio is permitted and encouraged, with shifts of emphasis among equities, fixed income securities and cash equivalents at the discretion of each manager. No target asset allocations are set forth in the investment policy. For our non-U.S. pension plans, our investment objective is generally met through the use of pooled investment funds and insurance contracts.

Equity securities consist primarily of publicly traded U.S. and non-U.S. common stocks. Equities are valued at closing prices reported on the listing stock exchange.

Table of Contents

Fixed income securities consist primarily of U.S. government and agency bonds and U.S. corporate bonds. Fixed income securities are valued at closing prices reported in active markets or based on yields currently available on comparable securities of issuers with similar credit ratings. When quoted prices are not available for identical or similar bonds, the bond is valued under a discounted cash flow approach that maximizes observable inputs, such as current yields of similar instruments, and may include adjustments, for certain risks that may not be observable, such as credit and liquidity risks.
A financial instrument's categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Pooled investment funds consist of mutual and collective investment funds that invest primarily in publicly traded non-U.S. equity and fixed income securities. Pooled investment funds are valued atusing the net asset values calculatedvalue (NAV) provided by the fund manageradministrator of the fund. The NAV is based on fairthe value of the underlying securities.assets owned by the fund, minus its liabilities, divided by the number of shares outstanding. The underlying securities are generally valued at closing prices reported in active markets, quoted prices of similar securities, or discounted cash flows approach that maximizes observable inputs such as current value measurement at the reporting date. These investments are not classified in the fair value hierarchy in accordance with guidance in ASU 2015-07.
Insurance contracts are valued in accordance with the terms of the applicable collective pension contract. The fair value of the plan assets equals the discounted value of the expected cash flows of the accrued pensions which are guaranteed by the counterparty insurer.
Cash equivalents consist primarily of money market and similar temporary investment funds. Cash equivalents are valued at closing prices reported in active markets.
The preceding methods may produce fair value measurements that are not indicative of net realizable value or reflective of future fair values. Although we believe the valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

We expect to make net contributions of $5.9$7.1 million to our pension plans in 20172019, which are primarily associated with our International segment.
For the 20162018 beginning of the year measurement purposes (net periodic benefit expense), a 6.5% increase in the costs of covered health care benefits was assumed, decreasing by 0.5% for each successive year to 4.5% in 20202022 and thereafter. For the 20162018 end of the year measurement purposes (benefit obligation), 6.0%a 6.5% increase in the costs of covered health care benefits was assumed, decreasing by 0.5% for each successive year to 4.5% in 20212023 and thereafter. A one-percentage-point change in assumed health care cost trend rates would have increased or decreased the other post-retirement benefit obligations and current year plan expense by approximately $810 thousand$1.0 million and $55 thousand,$0.1 million, respectively.
Expense for defined contribution pension plans was $9.0 million in 2018, $8.1 million in 2017 and $5.1 million in 2016, $6.8 million in 2015 and $6.5 million in 2014 .2016.
Estimated pension benefits to be paid under our defined benefit pension plans during the next five years are $20.9 million in 2017, $21.6 million in 2018, $22.2$29.8 million in 2019, $23.7$24.8 million in 2020, $24.6$25.7 million in 2021, $26.4 million in 2022 and are expected to aggregate $138.5$27.3 million in 2023, and an aggregated $145.1 million for the five years thereafter. Estimated other post-retirement benefits to be paid during the next five years are $1.7 million in 2017, $1.7 million in 2018, $1.9$2.8 million in 2019, $1.8$2.7 million in 2020, $1.9$2.8 million in 2021, $2.6 million in 2022, $2.3 million in 2023, and are expected to aggregate $8.1an aggregated $10.3 million for the five years thereafter.

During the yearyears ended December 31, 2018, 2017 and 2016, we recognized $4.6 million, $3.6 million and $2.8 million of income, respectively, related to interest earned on cash balances, short-term investments and notes receivable from insurance companies. Please refer to Note 19 19—Contingencies to the Consolidated Financial Statements in Part II Item 8 of this Form 10-K for further discussion on the Company's notes receivable from insurance companies.
During the year ended December 31, 2015, we recorded $4.2 million of losses associated with the disposal of net assets related to the Safety Works business in our Americas segment. A discounted cash flow valuation was also performed and showed that the book value of intangible assets used to support certain non-core product sales exceeded their fair value by $0.7 million in our Americas segment. Additionally, we recognized a $2.0 million gain on the sale of property in Australia, which is part of our International segment, as the Company continues to right-size operations and optimize its global footprint.
During the year ended December 31, 2014, we recognized a $2.2 million gain on the sale of detector tube assets in our International segment. All proceeds associated with this transaction were collected in 2014. Under the terms of the transitional agreements, we continued to manufacture and sell detector tubes on behalf of the buyer until mid-2014.
Note 16—Leases
We lease office space, manufacturing and warehouse facilities, automobiles and other equipment under operating lease arrangements. Rent expense was $12.5 million in 2018, $13.7 million in 2017 and $12.6 million in 2016, $10.8 million in 2015 and $11.7 million in 2014.2016. Minimum rent commitments under noncancellable leases are $12.2 million in 2017, $11.0 million in 2018, $10.6$11.2 million in 2019, $5.2$7.9 million in 2020, $4.2$6.1 million in 2021, $3.8 million in 2022, $2.6 million in 2023 and $7.0$2.0 million thereafter.
Note 17—Derivative Financial Instruments
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 basisat fair value and report the related gains or losses in currency exchange losses, (gains)net, in the consolidated statementConsolidated Statement of income.Income. At December 31, 2016,2018, the notional amount of open forward contracts was $75.3$72.4 million and the unrealized gain on these contracts was $0.3$0.5 million. All open forward contracts will mature during the first quarter of 2017.2019.

Note 18—Fair Value Measurements
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy are:
Level 1—Observable inputs that reflect unadjusted quoted prices for identical assets or liabilities in active markets.
Level 2—Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.
Level 3—Unobservable inputs for the asset or liability.
The valuation methodologies we used to measure financial assets and liabilities were limited to the pension plan assets described in Note 14 and the derivative financial instruments described in Note 17. See Note 14 for the fair value hierarchy classification of pension plan assets. We estimate the fair value of the derivative financial instruments, consisting of foreign currency forward contracts, based upon valuation models with inputs that generally can be verified by observable market conditions and do not involve significant management judgment. Accordingly, the fair values of the derivative financial instruments are classified within Level 2 of the fair value hierarchy.
With the exception of our investments in marketable securities and fixed rate long-term debt both as disclosed below, we believe that the reported carrying amounts of our remaining financial assets and liabilities approximate their fair values.
We value our investments in marketable securities, primarily fixed income, at fair value using quoted market prices for similar securities or pricing models. Accordingly, the fair values of the investments are classified within Level 2 of the fair value hierarchy. The amortized cost basis of our investments was $55.4 million as of December 31, 2018 and the fair value was $55.1 million which was reported in "Investments, short-term" in the accompanying Consolidated Balance Sheet. The change in fair value is recorded in other comprehensive income, net of tax. The Company does not intend to sell, nor is it more likely than not that we will be required to sell, these securities prior to recovery of their cost, as such, management believes that any unrealized gains or losses are temporary; therefore, no impairment gains or losses relating to these securities have been recognized.  The Company did not hold any investment securities as of December 31, 2017. All investments in marketable securities have maturities of one year or less and are currently in an unrealized loss position as of December 31, 2018.
The reported carrying amount of fixed rate long-term debt (including the current portion) was $175$130 million and $140$181 million at December 31, 20162018 and 2015,2017, respectively. The fair value of this debt was $194$139 million and $145$200 million at December 31, 20162018 and 2015,2017, respectively. The fair value of this debt was determined using Level 2 inputs by evaluating like rated companies with publicly traded bonds where available or current borrowing rates available for financings with similar terms and maturities.

Product Liabilityliability
The Company categorizes theWe face an inherent business risk of exposure to product liability lossesclaims arising from the alleged failure of its subsidiary MSA LLC into two main categories:our products to prevent the types of personal injury or death against which they are designed to protect. Product liability claims are categorized as either single incident andor cumulative trauma.
Single incident product liability 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 LLCThe Company estimates its liability for single incident product liability claims based on expected settlement costs for reportedasserted single incident product liability claims, and an estimate of costs for unreportedsingle incident product liability claims (claims incurred but not reported or IBNR)("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 reportedasserted single incident product liability claims and IBNR single incident product liability claims, was $3.4$3.6 million at December 31, 20162018 and $3.5$5.4 million at December 31, 2015.2017. Single incident product liability expense duringwas $2.0 million, $2.4 million and $0.8 million for the yearyears ended December 31, 2018, 2017 and 2016, was $0.8 million and was $0.9 million for the year ended December 31, 2015.respectively. 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 product liability 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. One of the Company's affiliates Mine Safety Appliances Company, LLC ("MSA LLC is presentlyLLC") was named as a defendant in 1,7941,481 lawsuits comprised of 3,023 claims.2,355 claims as of December 31, 2018. 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.

Cumulative trauma product liability litigation is inherently unpredictable.unpredictable and MSA LLC's expense with respect to cumulative trauma product liability claims could vary significantly in future periods. Factors that can limit ourMSA LLC's ability to estimate potential liability for cumulative trauma product liability claims include low volumes in the lacknumber of claims experienceasserted and resolved (both in general and with applicable plaintiffs’respect to particular plaintiffs' counsel, as claims experience can vary significantly among different counsel, low volume of resolution, lack of confidence with the consistencycounsel), inconsistency of claims composition, oruncertainty as to if and over what time periods claims might be asserted in the future, and other factors. With respect to the risk associated with any particular case that is filed against MSA LLC, 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 a 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. ComplaintsThe complaints initially filed generally dohave not provideprovided 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 casecase-by-case analysis of the relevant facts, including the nature of the injury, the jurisdiction in which the claim is filed, the plaintiffs' counsel for the plaintiff 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 inwith respect to particular claims and uncertainties surrounding the litigation process in different jurisdictions and from jurisdiction to jurisdiction and case to case. Consequently,case within a particular jurisdiction.
Management works with outside legal counsel quarterly to review and assess MSA LLC is unableLLC's exposure to comprehensively estimate itsasserted cumulative trauma product liability exposure.
Currentlyclaims not yet resolved. In addition, in connection with finalizing and reporting its results of operations, management works annually (unless significant changes in consultationtrends or new developments warrant an earlier review) with itsan outside valuation consultant and outside legal counsel has been unable to estimate,review MSA LLC's exposure to all cumulative trauma product liability claims. The review process for asserted cumulative trauma product liability claims not yet resolved takes into account available facts for those claims, including their number and therefore has not recorded any liability, for MSA LLC’s IBNRcomposition, outcomes of matters resolved during current and prior periods, and variances associated with different groups of claims, plaintiffs' counsel, claims filing trends, and venues, as well as any other relevant information.
In August 2017, MSA LLC obtained additional detailed information about a significant number of claims that were then pending against it, including the nature and extent of the alleged injuries, product identification and other factors. MSA LLC subsequently agreed to resolve a substantial number of these claims, for certain$75.2 million, a portion of which was insured. Amounts in excess of estimated insurance recoveries were reflected within Other operating expense in the Consolidated Statement of Income. MSA LLC paid a total of $28.6 million and $25.2 million during 2018 and 2017, respectively. related to these settlements. MSA LLC expects to pay $7.1 million ratably over each of the next three quarters ending in the third quarter of 2019.

In the fourth quarter of 2017, MSA LLC, in consultation with an outside valuation consultant and outside legal counsel, performed a review for IBNR cumulative trauma product liability claims. Based on that review process, which concluded in early 2018, it was determined that a reasonable estimate for the liability of MSA LLC's IBNR claims was $111.1 million. Accordingly, the cumulative trauma product liability reserve was increased by $111.1 million for estimated IBNR cumulative trauma product liability claims.

The ability to make a reasonable estimate of the potential liability for IBNR cumulative trauma product liability claims in 2017 resulted from recent developments affecting asbestos claims, recent developments affecting silica claims, and recent developments affecting coal dust claims. Significant changes in MSA LLC’s claims experience over the last few years have resulted in stabilization of a number of factors important to the estimation process and enabled greater predictability of IBNR claims. These developments occurred as a result of changes in defense strategy implemented in recent years, increased experience in defending, negotiating, and resolving key groups of claims, and resolutions of a substantial number of cumulative trauma product liability claims in the last few years. These changes collectively resulted in MSA LLC having a more stable recent claims history that could be extrapolated into the future and greater certainty as to the number of claims that might be asserted against MSA LLC in the future, the percentage of those claims that might be resolved without payment, and the potential settlement value of those claims that are not resolved without payment. All of these factors were considered by MSA LLC’s valuation consultant in estimating the IBNR cumulative trauma product liability claims. MSA LLC, taking into account the analysis and estimates developed by its existingconsultant, concluded that reasonable estimates for its IBNR asbestos, silica and coal dust claims including those coal dust claimscould be made and that arose subsequent to the Couch verdictliability described below.above was accrued.

At December 31, 2015,There remains considerable uncertainty in numerous aspects of MSA LLC's potential future claims experience, such as with respect to the number of claims that might be asserted, the alleged severity of those claims and the average settlement values of those claims, and that uncertainty may cause actual claims experience in the future to vary from the current estimate. Numerous uncertainties also exist with respect to factors not specific to MSA LLC’s claims experience, including potential legislative or judicial changes at the federal level or in key states concerning claims adjudication, future bankruptcy proceedings involving key co-defendants, payments from trusts established to compensate claimants, and/or changes in medical science relating to the diagnosis and treatment of cumulative trauma product liability claims. If future estimates of asserted cumulative trauma product liability claims not yet resolved and/or IBNR cumulative trauma product liability claims are materially higher (lower) than the accrued liability, we will record an appropriate charge (credit) to the Consolidated Statement of Income to increase (decrease) the accrued liability.

Certain significant assumptions underlying the material components of the accrual for IBNR cumulative trauma product liability claims include MSA LLC's experience related to the following:

The types of illnesses alleged by claimants to give rise to their claims;

The number of claims asserted against MSA LLC;

The propensity of claimants and their counsel asserting cumulative trauma product liability claims to name MSA LLC establishedas a $7.1 milliondefendant;
The percentage of cumulative trauma product liability claims asserted against MSA LLC that are dismissed without payment;
The average value of settlements paid to claimants; and

The jurisdiction in which claims are asserted.

Additional assumptions include the following:

MSA LLC will continue to evaluate and handle cumulative trauma product liability claims in accordance with its existing defense strategy;

The number and effect of co-defendant bankruptcies will not materially change in the future;

No material changes in medical science occur with respect to cumulative trauma product liability claims; and

No material changes in law occur with respect to cumulative trauma product liability claims including, in particular, no material state or federal tort reform actions affecting such claims.

Total cumulative trauma product liability reserve was $187.3 million, including $24.5 million for reported claims. During 2016, we increased this reserve by $0.4 million to $7.5 millionclaims settled but not yet paid and related defense costs, as of December 31, 2016.2018 and $181.1 million, including $54.5 million for claims settled but not yet paid and related defense costs, as of December 31, 2017. This reserve includes estimated amounts for asserted claims not yet resolved and IBNR claims. Those estimated amounts reflect asbestos, silica, and coal dust claims expected to be asserted through the year 2069 and are not discounted to present value. The totalCompany revised its estimates of MSA LLC's potential liability for cumulative trauma product liability reserve,claims for the current year as a result of its annual review process described above. The revisions to the Company’s estimates of potential liability for cumulative trauma product liability claims are based on an assessment of trends in the tort system generally and changes in MSA LLC’s claims experience over the past year, including the estimated reserve for reportednumber of claims asserted, average value of settlements paid to claimants, the number and settlements that have not yet been paid, totaled $11.1 million at December 31, 2016.

Insurance Receivable and Notes Receivable, Insurance Companies
In the year over year variabilitynormal course of our financial results.
On February 26, 2016, a Kentucky state court jury in the James Couch claim rendered a verdict againstbusiness, MSA LLC of $7.2 million dollars (comprised of $3.2 million of an apportioned share of compensatory damagesmakes payments to settle various claims and $4.0 million in punitive damages). The Couch claim is afor related defense costs and records receivables for the estimated amounts that are covered by insurance. With respect to cumulative trauma product liability lawsuit involving exposure to coal dust.Management believes that the verdict against MSA LLC is inconsistent with Kentucky law and many issues have been raised on appeal, including the statute of limitations, failure to meet the standard of causation and the appropriate application of punitive damages. The Company and its outside legal counsel have concluded that, based on their assessment of the appellate issues, a reversal of the adverse judgment is reasonably possible and, consequently, a loss contingency is not probable at this time and is not included in the $7.5 million product liability reserve as of December 31, 2016. In the future, if the Company determines that losses with respect to this matter are probable, MSA LLC, consistent with its existing practices, will record an accrual and provide appropriate disclosures as required by ASC 450-20-50, Contingencies. In the event that MSA LLC’s appeal of the adverse verdict is unsuccessful or not fully successful, the loss could total the full amount of the verdict, plus additional amounts for post-judgment interest. If so, the $3.2 million compensatory portion of the verdict (and associated interest) would be added to the product liability reserve and the insurance receivable, to the extent insurance is available. The $4.0 million punitive portion of the verdict (and associated interest) would be expensed because we do not have insurance to cover punitive damages in this case.
Insurance Receivable
claims, MSA LLC purchased insurance policies for the policy years from 1952-1986 from over 20 different insurance carriers that, subject to some common contract exclusions, provideprovided coverage for cumulative trauma product liability losses and, in many instances, related defense costs (the "Occurrence-Based Policies"). After 1986, MSA LLC’s insurance policiesThe Occurrence-Based Policies have significant per claim deductibles. Based on this, the Company does not expect to be materially reimbursedretentions and applicable exclusions for any claims alleging exposures that occurred entirely after this date.
In the normal course of business, MSA LLC makes payments to settlecumulative trauma product liability claims after April 1986. While we continue to pursue reimbursement under certain policies, the vast majority of these insurance policies have been exhausted, settled or converted into negotiated coverage-in-place agreements with the applicable insurers (the "Coverage-In-Place Agreements"). As a result, MSA LLC is now largely self-insured for cumulative trauma product liability claims.
Since MSA LLC is now largely self-insured for cumulative trauma product liability claims, additional amounts recorded as insurance receivables will be limited and for related defense costs and records receivables forbased on calculating the amounts that are covered by insurance. The available limits of the applicable Occurrence-Based Policies exceed the recorded insurance receivable balance.to be reimbursed pursuant to negotiated Coverage-In-Place Agreements. Various factors could affect the timing and amount of recovery of the insurance receivable,receivables, including assumptions regarding claims composition (which are relevant to calculating reimbursement under the outcometerms of negotiations with insurers and the outcome of the coverage litigation with respect to the Occurrence-Based Policies,certain Coverage-In-Place Agreements) and the extent to which the issuing insurers may become insolvent in the future.

Total cumulative trauma liability losses were $63.8 million, $219.0 million, and $30.5 million for the years as well as the recent trial verdict against North River, which resulted in a favorable outcome, demonstrate that we have strong legal positions concerning MSA LLC's rights to coverage. The trial verdict is described below.

Insurance Litigation

For more than a decade, MSA LLC is currently involvedwas engaged in insurance coverage litigation with a numbermany of its insurance carriers regarding itsthat issued Occurrence-Based Policies.
In 2009, MSA LLC (as Mine Safety Appliances Company) sued The North River Insurance Company (North River) in the United States District Court for the Western District of Pennsylvania, alleging that North River breached one of its insurance policies by failing to pay amounts owed to MSA LLC and that it engaged in bad-faith claims handling. MSA LLC believes that North River’s refusal to indemnify it under the policy for product liability losses and legal fees paid by MSA LLC is wholly contrary to Pennsylvania law and MSA LLC is vigorously pursuing the legal actions necessary to collect all due amounts. A trial date has not yet been scheduled.

In 2010, North River sued MSA LLC (as Mine Safety Appliances Company) in the Court of Common Pleas of Allegheny County, Pennsylvania seeking a declaratory judgment concerning their responsibilities under three additional policies. MSA LLC asserted claims against North River for breaches of contract for failures to pay amounts owed to MSA LLC. MSA LLC also alleged that North River engaged in bad-faith claims handling.
On October 6, 2016, a Pennsylvania state court jury found that North River breached the three contracts at issue in the case, and that North River also violated common law standards of bad faith in handling MSA LLC's clams. As a result of the jury's findings, the court entered a verdict in favor of MSA LLC and against North River for $10.9 million, the full amount of the contractual damages at issue in the case. The $10.9 million, which is comprised of previously recorded payments to settle product liability claims and related defense costs, is part of MSA LLC's insurance receivable. In addition to the claims decided by the jury, MSA LLC also presented a claim under Pennsylvania's bad faith statue, which is decided by the court. Following the jury verdict, the court also issued a verdict finding that North River had acted in bad faith. In December 2016 and January 2017, the Pennsylvania state court heard evidence regarding the extent of damages awardable as a result of the statutory bad faith claim. In an order dated February 9, 2017, the Court of Common Pleas of Allegheny County awarded MSA LLC an additional $46.9 million in damages related to this statutory bad faith claim. The $46.9 million award was comprised of $30.0 million in punitive damages, $11.8 million in attorneys' fees, and $5.1 million in pre-judgment interest, each of which is authorized by a Pennsylvania statute covering bad faith claims handling matters. The court will hear post-trial motions through mid-second quarter.
In July 2010, MSA LLC (as Mine Safety Appliances Company) filed a lawsuit in the Superior Court of the State of Delaware seeking declaratory and other relief from the majority of its excess insurance carriers concerning the future rights and obligations of MSA LLC and its excess insurance carriers under various insurance policies. During the same time period, MSA LLC was also engaged in coverage disputes with The reason for this insurance coverage action is to secure a comprehensive resolutionNorth River Insurance Company (“North River”) in various courts. Since 2010, MSA LLC reached negotiated resolutions with the vast majority of its rights under the insurance policies issued bycarriers once in litigation, including the insurers. Trial is scheduled forJuly 2018 settlement with North River disclosed below.
In February 2017, MSA LLC resolved through a negotiated settlement its coverage litigation with The Hartford ("Hartford").  Additionally, in April 2017.
Through2017, MSA LLC resolved through negotiated settlements MSA LLC has resolved claims against certainits coverage litigation with Travelers Insurance Company ("Travelers") and Wausau Indemnity Company ("Wausau").  Each of its insurance carriers on certain policies. When a settlement is reached, MSA LLC dismisses the settling carrier from the relevant above noted lawsuit(s). Assuming satisfactory resolution, once disputes are resolved with eachcarriers agreed to cash payments which were made in 2017 or January 2018. In addition, Travelers has agreed to pay a percentage of the remaining carriers, MSA LLC anticipates having commitments to provide future payment streams which should be sufficient to satisfy its presently recorded insurance receivables due from insurance carriers.
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. 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 settlements paid as incurred on a claim-by-claim basis.  As part of these settlements, MSA LLC dismissed all claims against Hartford, Travelers and Wausau in the coverage litigation in the Superior Court of the State of Delaware.

In July 2018, MSA LLC resolved through a negotiated settlement its remaining coverage litigation with North River. As part of this settlement, in October 2018, MSA LLC dismissed all claims and appeals against North River in each of the pending coverage actions. This represents a settlement with MSA LLC’s last major Occurrence-Based insurance carrier. Payment under this negotiated settlement was received in the third quarter of 2018 and was accounted for as a reduction of the insurance receivable balance.
Product Warranty
The Company provides warranties on certain product sales. Product warranty reserves are established in the same period that revenue from the sale of the related products is recognized, or in the period that a specific issue arises as to the functionality of a Company's product. The determination of such reserves requires the Company to make estimates of product return rates and expected costs to repair or to replace the products under warranty.
The amounts of the reserves are incurredbased on established terms and the resultsCompany's best estimate of litigationthe amounts necessary to settle future and negotiations with insurance carriers. After it becomes largely self-insured, MSA LLCexisting claims on products sold as of the balance sheet date. If actual return rates and/or repair and replacement costs differ significantly from estimates, adjustments to recognize additional cost of sales 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.  required in future periods.

Note 20—Discontinued Operations
On February 29, 2016, the Company sold 100% of the stock associated with its South African personal protective equipment distribution business and its Zambian operations, which were reported in the International segment.
The Company received $15.9 million from the closing of this transaction and recorded a loss of approximately $0.3 million during the first quarter of 2016.
During the second quarter of 2016, the Company corrected its gain calculation on the disposition of the South African personal protective equipment distribution business and its Zambian operations. This resulted in a gain of approximately $2.5 million being recorded during the second quarter in discontinued operations that should have been recorded in the first quarter of 2016. The Company evaluated materiality in accordance with SEC Staff Accounting Bulletins Topics 1.M and 1.N and considered relevant qualitative and quantitative factors. The Company concluded that this modification was not material to the first quarter of 2016 or the trend in earnings over the affected periods. The modification had no effect on cash flows or debt covenant compliance.
The operations of this business qualify as a component of an entity under FASB ASC 205-20 "Presentation of Financial Statements - Discontinued Operations", and thus, the operations have been reclassified as discontinued operations and prior periods have been reclassified to conform to this presentation.

Item 9A. Controls and Procedures
(a) Evaluation of disclosure controls and procedures. Based on their evaluation as of the end of the period covered by this Form 10-K, the Company’s principal executive officer and principal financial officer have concluded that the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”)) are effective to ensure that information required to be disclosed by the Company in reports that it files or submits under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms and (ii) accumulated and communicated to our management, including the principal executive officer and principle financial officer, as appropriate to allow timely decisions regarding required disclosure.
Management has excluded Senscient from its assessment of internal control over financial reporting as of December 31, 2016 because it was acquired by the Company in a purchase business combination late in the third quarter of 2016. Senscient is wholly-owned by MSA.

There were no changes in the Company’s internal control over financial reporting that occurred during the Company’s most recent fiscal quarter, that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
