As used in this Annual Report on Form 10-K, the term "Company," except as otherwise indicated by the context, means Lincoln Electric Holdings, Inc. and its wholly-owned and majority-owned subsidiaries for which it has a controlling interest. The Lincoln Electric Company began operations in 1895 and was incorporated under the laws of the State of Ohio in 1906. During 1998, The Lincoln Electric Company reorganized into a holding company structure, and Lincoln Electric Holdings, Inc. became the publicly-held parent of Lincoln Electric subsidiaries worldwide, including The Lincoln Electric Company.

The Company is one of only a few worldwide broad-line manufacturers of welding, cutting and brazing products. Welding products include arc welding power sources, plasma cutters, wire feeding systems, robotic welding packages, integrated automation systems, fume extraction equipment, consumable electrodes, fluxes and fluxes.welding accessories. The Company's product offering also includes computer numeric controlled ("CNC") plasma and oxy-fuel cutting systems and regulators and torches used in oxy-fuel welding, cutting and brazing. In addition, the Company has a leading global position in the brazing and soldering alloys market.

The arc welding power sources and wire feeding systems manufactured by the Company range in technology from basic units used for light manufacturing and maintenance to highly sophisticated robotic applications for high volume production welding and fabrication. Three primary types of arc welding electrodes are produced: (1) coated manual or stick electrodes; (2) solid electrodes produced in coil, reel or drum forms for continuous feeding in mechanized welding; and (3) cored electrodes produced in coil form for continuous feeding in mechanized welding.

The Company has, through wholly-owned subsidiaries or joint ventures, manufacturing facilities located in the United States, Australia, Brazil, Canada, China, Colombia, France, Germany, India, Indonesia, Italy, Mexico, the Netherlands, Poland, Portugal, Russia, Turkey, the United Kingdom and Venezuela.

The Company has aligned itsAs of December 31, 2015, the Company's business units were aligned into five operating segments to enhance the utilization of the Company's worldwide resources and global end user and sourcing initiatives.segments. The operating segments consist of North America Welding, Europe Welding, Asia Pacific Welding, South America Welding and The Harris Products Group. The North America Welding segment primarily includes welding operations in the United States, Canada and Mexico. The Europe Welding segment includes welding operations in Europe, Russia, Africa and the Middle East. The Asia Pacific Welding segment primarily includes welding operations in China and Australia. The South America Welding segment primarily includes welding operations in Brazil, Colombia and Venezuela. The Harris Products Group includes the Company's global cutting, soldering and brazing businesses as well as the retail business in the United States. See Note 5 to the Company's consolidated financial statements for segment and geographic area information, which is incorporated herein by reference.

The Company's products are sold in both domestic and international markets. In North America, products are sold principally through industrial distributors, retailers and also directly to users of welding products. Outside of North America, the Company has an international sales organization comprised of Company employees and agents who sell products from the Company's various manufacturing sites to distributors and product users.

The Company's major end-user markets include:

The Company is not dependent on a single customer or a few customers and no individual customer currently accounts for more than ten percent of total Net sales. However, the loss of a large customer could have an adverse effect on the Company's business. The Company's operating results are sensitive to changes in general economic conditions. The arc welding and cutting industry is generally a mature industry in developed markets such as North America and Western Europe and is cyclical in nature. Overall demand for arc welding and cutting products is largely determined by economic cycles and the level of capital spending in manufacturing and other industrial sectors. The Company experiences some variability in reported period-to-period results as demand for the Company's products are mildly seasonal with generally higher demand in the second and third quarters. See "Item 1A. Risk Factors" for further discussion regarding risks associated with customers, general economic conditions and demand.

Conditions in the arc welding and cutting industry are highly competitive. The Company believes it is the world's largest manufacturer of consumables and equipment with relatively few major broad-line competitors worldwide, but numerous smaller competitors in specific geographic markets. The Company continues to pursue strategies to heighten its competitiveness in domestic and international markets, which includes positioning low cost manufacturing facilities in most geographical markets. Competition in the arc welding and cutting industry is based on brand preference, product quality, price, performance, warranty, delivery, service and technical support. The Company believes its performance against these factors has contributed to the Company's position as the leader in the industry.

Most of the Company's products may be classified as standard commercial articles and are manufactured for stock. The Company believes it has a competitive advantage in the marketplace because of its highly trained technical sales force and the support of its welding research and development staff to assist customers in optimizing their welding applications. This allows the Company to introduce its products to new users and to establish and maintain close relationships with its customers. This close relationship between the technical sales force and the direct customers, together with its supportive relationship with its distributors, who are particularly interested in handling the broad range of the Company's products, is an important element of the Company's market success and a valuable asset of the Company.

The principal raw materials essential to the Company's business are steel, electronic components, engines, brass, copper, silver, aluminum alloys and various chemicals, all of which are normally available for purchase in the open market.

The Company holds many valuable patents, primarily in arc welding, and has increased the application process as research and development has progressed in both the United States and major international jurisdictions. The Company believes its trademarks are an important asset and aggressively pursues brand management.

The Company conducts a significant amount of its business and has a number of operating facilities in countries outside the United States. As a result, the Company is subject to business risks inherent to non-U.S. activities, including political uncertainty, import and export limitations, exchange controls and currency fluctuations.

Research activities, which the Company believes provide a competitive advantage, relate to the development of new products and the improvement of existing products. Research activities are Company-sponsored. Refer to Note 1 to the Company's consolidated financial statements with respect to total costs of research and development, which is incorporated herein by reference.

The Company's website, www.lincolnelectric.com, is used as a channel for routine distribution of important information, including news releases and financial information. The Company posts its filings as soon as reasonably practicable after they are electronically filed with, or furnished to, the SEC, including annual, quarterly and current reports on Forms 10-K, 10-Q and 8-K; proxy statements; and any amendments to those reports or statements. The Company also posts its Code of Corporate Conduct and Ethics on its website. All such postings and filings are available on the Company's website free of charge. In addition, this website allows investors and other interested persons to sign up to automatically receive e-mail alerts when news releases and financial information is posted on the website. The SEC also maintains a website, www.sec.gov, that contains reports, proxy and information statements and other information regarding issuers that file electronically with the SEC. The content on any website referred to in this Annual Report on Form 10-K is not incorporated by reference into this Annual Report unless expressly noted.

From time to time, information we provide, statements by our employees or information included in our filings with the SEC may contain forward-looking statements that are not historical facts. Those statements are "forward-looking" within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements generally can be identified by the use of words such as "may," "will," "expect," "intend," "estimate," "anticipate," "believe," "forecast," "guidance" or words of similar meaning. Actual results may differ materially from such statements due to a variety of factors that could adversely affect the Company's operating results. Forward-looking statements, and our future performance, operating results, financial position and liquidity, are subject to a variety of factors that could materially affect results, including those risks described below. Any forward-looking statements made in this report or otherwise speak only as of the date of the statement, and, except as required by law, we undertake no obligation to update those statements. Comparisons of results for current and any prior periods are not intended to express any future trends or indications of future performance, unless expressed as such, and should only be viewed as historical data.

In the ordinary course of our business, we face various strategic, operating, compliance and financial risks. These risks could have a material impact on our business, financial condition, operating results and cash flows.

Our Enterprise Risk Management ("ERM") process seeks to identify and address significant risks. Our ERM process is a company-wide initiative that is designed with the intent of prioritizing risks and allocating appropriate resources to address such risks. We use the integrated risk framework of the Committee of Sponsoring Organizations to assess, manage and monitor risks.

Management has identified and prioritized critical risks based on the severity and likelihood of each risk and assigned an executive to address each major identified risk area and lead action plans to monitor and mitigate risks, where possible. Our Board of Directors provides oversight of the ERM process and systematically reviews identified critical risks. The Audit Committee also reviews major financial risk exposures and the steps management has taken to monitor and control them.

Our goal is to pro-actively manage risks in a structured approach and in conjunction with the strategic planning process, with the intent to preserve and enhance shareholder value. However, these and other risks and uncertainties could cause our results to vary materially from recent results or from our anticipated future results. The risk factors and uncertainties described below, together with information incorporated by reference or otherwise included elsewhere in this Annual Report on Form 10-K, should be carefully considered. Additional risks and uncertainties of which we are currently unaware or that we currently believe to be immaterial may also adversely affect our business.

Our operating results are sensitive to changes in general economic conditions. Further recessionary economic cycles, higher interest rates, inflation, higher labor costs, trade barriers in the world markets, financial turmoil related to sovereign debt and changes in tax laws or other economic factors affecting the countries and industries in which we do business could adversely affect demand for our products, thereby impactingproducts. An adverse change in demand could impact our results of operations, collection of accounts receivable and our expected cash flow generation from current and acquired businesses, which may adversely impact our financial condition and access to capital markets.

Our facilities and operations, and the facilities and operations of our suppliers and customers, could be disrupted by events beyond our control, such as war, political unrest, public health concerns,pandemic, labor disputes or natural disasters. Any such disruption could cause delays in the production and distribution of our products and the loss of sales and customers. Insurance proceeds may not adequately compensate the Company for the losses.

In the normal course of business, we are exposed to market risks related to the availability of and price fluctuations in the purchase of energy and commodities used in the manufacture of our products (primarily steel, brass, copper, silver, aluminum alloys, electronic components, electricity and natural gas). The availability and prices for energy costs and raw materials, including steel, nonferrous metals and chemicals, are subject to volatility and are influenced by worldwide economic conditions, speculative action, world supply and demand balances, inventory levels, availability of substitute materials, currency exchange rates, our competitors' production costs, anticipated or perceived shortages and other factors.

Increases in the cost of raw materials and components may adversely affect our profitability if we are unable to pass along to our customers these cost increases in the form of price increases or otherwise reduce our cost of goods sold. Although most of the raw materials and components used in our products are commercially available from a number of sources and in adequate supply, any disruption in the availability of such raw materials and components, our inability to timely or otherwise obtain substitutes for such items, or any deterioration in our relationships with or the financial viability of our suppliers could adversely affect our business.

The long-term impact of the asbestos loss contingency, in the aggregate, on operating results, operating cash flows and access to capital markets is difficult to assess, particularly since claims are in many different stages of development and we benefit significantly from cost-sharing with co-defendants and insurance carriers. While we intend to contest these lawsuits vigorously, and believe we have applicable insurance relating to these claims, there are several risks and uncertainties that may affect our liability for personal injury claims relating to exposure to asbestos, including the future impact of changing cost sharing arrangements or a change in our overall trial experience.

Asbestos use in welding consumables in the U.S. ceased in 1981.

Our business exposes us to potential product liability risks that are inherent in the design, manufacture, sale and application of our products and the products of third-party suppliers that we utilize or resell. Our products are used in a variety of applications, including infrastructure projects such as oil and gas pipelines and platforms, buildings, bridges and power generation facilities, the manufacture of transportation and heavy equipment and machinery and various other construction projects. We face risk of exposure to product liability claims in the event that accidents or failures on these projects result, or are alleged to result, in bodily injury or property damage. Further, our products are designed for use in specific applications, and if a product is used inappropriately, personal injury or property damage may result.

The occurrence of defects in or failures of our products, or the misuse of our products in specific applications, could cause termination of customer contracts, increased costs and losses to us, our customers and other end users. We cannot be assured that we will not experience any material product liability losses in the future or that we will not incur significant costs to defend those claims. Further, we cannot be assured that our product liability insurance coverage will be adequate for any liabilities that we may ultimately incur or that product liability insurance will continue to be available on terms acceptable to us. Even if we are successful defending such claims or product liability coverage is adequate, claims of this nature could cause customers to lose confidence in our products and our company. Warranty claims are not generally covered by insurance and we may incur significant warranty costs in the future for which we would not be reimbursed.

The arc welding and cutting industry is generally a mature industry in developed markets such as North America and Western Europe and is cyclical in nature. Overall demand for arc welding and cutting products is largely determined by the level of capital spending in manufacturing and other industrial sectors, and the welding industry has historically experienced contraction during periods of slowing industrial activity. If economic, business and industry conditions deteriorate, capital spending in those sectors may be substantially decreased, which could reduce demand for our products, our revenues and our results of operations.

Part of our business strategy is to pursue targeted business acquisition opportunities, including foreign investment opportunities. For example, we have completed and continue to pursue acquisitions in emerging markets including, but not limited to, Brazil, Russia, India and China in order to strategically position resources to increase our presence in growing markets. We cannot be certain that we will be successful in pursuing potential acquisition candidates or that the consequences of any acquisition would be beneficial to us. Future acquisitions may expose us to unexpected liabilities and involve the expenditure of significant funds and management time. Further, we may not be able to successfully integrate any acquired business with our existing businesses or recognize the expected benefits from any completed acquisition.

Depending on the nature, size and timing of future acquisitions, we may be required to raise additional financing, which may not be available to us on acceptable terms. Our current operational cash flow is sufficient to fund our current acquisition plans, but a significant acquisition could require access to the capital markets.

Our abilityAdditionally, from time to complete the divestiture of assets, or interests in assets, may be subject to factors beyond our control, and in certain casestime we may be required to retain liabilities for certain matters.

Sellers typically retain certain liabilities or indemnify buyers for certain matters. The magnitude of any such retained liability or indemnification obligation may be difficult to quantify at the time of the transaction and ultimately may be material. Also, as is typical in divestitures, third parties may be unwilling to release us from guarantees or other credit support provided prior to the sale of the divested assets. As a result, after a divestiture, we may remain secondarily liable for the obligations guaranteed or supported to the extent that the buyer of the assets fails to perform these obligations.

Our continued success depends, in part, on our ability to continue to meet our customers' needs for welding and cutting products through the introduction of innovative new products and the enhancement of existing product design and performance characteristics. We must remain committed to product research and development and customer service in order to remain competitive. We cannot be assured that new products or product improvements, once developed, will meet with customer acceptance and contribute positively to our operating results, or that we will be able to continue our product development efforts at a pace to sustain future growth. Further, we may lose customers to our competitors if they demonstrate product design, development or manufacturing capabilities superior to ours.

We operate in a highly competitive global environment and compete in each of our businesses with other broad-line manufacturers and numerous smaller competitors specializing in particular products. We compete primarily on the basis of brand, product quality, price, performance, warranty, delivery, service and technical support. We have previously initiated, and may in the future initiate significant rationalization activities to align our business to market conditions.conditions and improve our overall competitiveness. Such rationalization activities could fail to deliver the desired competitive cost structure and could result in disruptions in customer service. If our products, services, support and cost structure do not enable us to compete successfully based on any of the criteria listed above, our operations, results and prospects could suffer.

Further, in the past decade, the arc welding industry in the United States and other developed countries has been subject to increased levels of foreign competition as low cost imports have become more readily available. Our competitive position could also be harmed if new or emerging competitors become more active in the arc welding business. For example, while steel manufacturers traditionally have not been significant competitors in the domestic arc welding industry, some foreign integrated steel producers manufacture selected consumable arc welding products. In addition, in certain markets of the world, distributors manufacture and sell arc welding products. Our sales and results of operations, as well as our plans to expand in some foreign countries, could be adversely affected by this practice.

Our long-term strategy is to continue to increase our market share in growing international markets. The share of sales and profits we derive from our international operations and exports from the United States is significant. This trend increases our exposure to the performance of many developing economies in addition to the developed economies outside of the United States. If international economies were to experience significant slowdowns, it could adversely affect our financial condition, results of operations and cash flows.

There are a number of risks in doing business internationally, which may impede our ability to achieve our strategic objectives relating to our foreign operations. Many developing countries have a significant degree of political and economic uncertainty and social turmoil that may impede our ability to implement and achieve our international growth objectives. Conducting business internationally subjects us to corporate governance and management challenges in consideration of the numerous U.S. and foreign laws and regulations, including regulations relating to import-export control, technology transfer restrictions, repatriation of earnings and funds, exchange controls, labor regulations, nationalization, anti-boycott provisions and anti-bribery laws (such as the Foreign Corrupt Practices Act and the Organization for Economic Cooperation and Development Convention). Failure by the Company or its sales representatives, agents or distributors to comply with these laws and regulations could result in administrative, civil or criminal liabilities, all or any of which could negatively impact our business and reputation. Our foreign operations also subject us to the risks of international terrorism and hostilities.

In particular, the economic and political environment in Venezuela exposes us to various risks. Currency exchange restrictions limit our ability to convert bolivars to U.S. dollars, which impacts our ability to repatriate earnings and to purchase goods and services necessary to operate our Venezuelan business. The restrictions could cause a slowdown, temporary shutdown or complete shutdown of operations at our Venezuelan subsidiary, which could negatively affect our earnings and cash flows.

Our success depends in part on the efforts and abilities of our management team and key employees. Their skills, experience and industry knowledge significantly benefit our operations and performance. Our future success will also depend on our ability to identify, attract and retain highly qualified managerial and technical (including research and development), sales and marketing, and customer service personnel. Competition for these individuals is intense, and we may not succeed in identifying, attracting or retaining qualified personnel. With our strategy to expand internationally into developing markets, we may incur additional risks as some developing economies lack a sufficiently trained labor pool.

Any interruption of our workforce, including interruptions due to unionization efforts, changes in labor relations or shortages of appropriately skilled individuals could impact our results of operations and financial condition.

Our businesses, results of operations or financial condition could be adversely affected if laws, regulations or standards relating to us, our products or the markets in which we operate are newly implemented or changed. New or revised laws, regulations or standards could increase our cost of doing business or restrict our ability to operate our business and execute our strategies.

Although our financial results are reported in U.S. dollars, a significant portion of our sales and operating costs are realized in other currencies. Our profitability is affected by movements of the U.S. dollar against other foreign currencies in which we generate revenues and incur expenses. Significant fluctuations in relative currency values, in particular an increase in the value of the U.S. dollar against foreign currencies, could have an adverse effect on our profitability and financial condition.

Our business is subject to income taxes in the United States and various foreign jurisdictions. Domestic and international tax liabilities are subject to the allocation of income among various tax jurisdictions. Our effective tax rate could be adversely affected by changes in the mix among earnings in countries with differing statutory tax rates, changes in the valuation allowances of deferred tax assets or changes in tax laws.

The amount of income taxes paid is subject to ongoing audits by United States federal, state and local tax authorities and by foreign tax authorities. If these audits result in assessments different from amounts reserved, future financial results may include unfavorable adjustments which could have a material adverse effect on our results of operations.

The conduct and management of our business relies extensively on information technology systems.systems, which contain confidential information related to our customers, suppliers and employees and other proprietary business information. We maintain some of these systems and are also dependent on a number of critical corporate infrastructure services provided by third parties relating to, among other things, human resources, electronic communication services and finance functions. If these systems are damaged, cease to function properly or are subject to a significant cyber security breach, we may suffer an interruption in our ability to manage and operate the business and our results of operations and financial condition could be adversely affected. Furthermore, a security breach could result in unfavorable publicity, damage to our reputation, loss of our trade secrets and other competitive information, allegations by our customers that we have not performed our contractual obligations, litigation by affected parties and fines and other sanctions resulting from any related breaches of data privacy regulations. Any of these could have an adverse effect on our results of operations and financial condition.

We are subject to increasingly complex environmental regulations affecting international manufacturers, including those related to air and water emissions, waste management and climate change.

Changes in environmental laws or regulations could result in newhigher expenses and payments, and uncertainty relating to environmental laws or additional regulatory or product standard requirements for the Company's global businesses. We are unable, at this time,regulations may also affect how we conduct our operations and structure our investments and could limit our ability to predict the significance of these requirements as the impact of any future GHG legislative, regulatory or product standards is dependent on the timingenforce our rights. Changes in environmental and design of the mandates or standards. Furthermore, the potential physical impacts of theorized climate change on the Company's customers,laws or regulations, including laws relating to greenhouse gas emissions, could subject us to additional costs and therefore on the Company'srestrictions, including increased energy and raw material costs. If environmental laws or regulations are either changed or adopted and impose significant operational restrictions and compliance requirements upon us or our products, they could negatively impact our business, capital expenditures, results of operations, are speculativefinancial condition and highly uncertain, and would be particular to the circumstances developing in various geographical regions. These potential physical effects may adversely impact the cost, production, sales and financial performance of the Company's operations which we are unable, at this time, to predict.competitive position.

It is our policy to apply strict standards for environmental protection to all of our operations inside and outside of the United States, even when we are not subject to local government regulations. We may incur substantial costs, including cleanup costs, fines and civil or criminal sanctions, liabilities resulting from third-party property damage or personal injury claims, or our products could be enjoined from entering certain jurisdictions, if we were to violate or become liable under environmental laws or if our products become non-compliant with environmental laws.

We also face increasing complexity in our products design and procurement operations as we adjust to new and future requirements relating to the design, production and labeling of our products that are sold worldwide in multiple jurisdictions. The ultimate costs under environmental laws and the timing of these costs are difficult to predict,predict.

Throughout 2015, we implemented rationalization plans and incurred employee severance and other related costs totaling $13,719. For more information regarding our rationalization plans, refer to the rationalization and asset impairment related disclosure under some environmental laws relatingNote 6 to contaminated locations canthe Company's consolidated financial statements. We may take additional actions in the future to further optimize our cost structure and improve the efficiency of our operations, which will reduce our profitability in the periods incurred. As a result of these actions, we will likely continue to incur charges, which may include but are not be imposed retroactivelylimited to asset impairments, employee severance costs, charges for pension and other postretirement contractual benefits and pension settlements, any of which could be significant, and could adversely affect our financial condition and results of operations. In addition, we may not realize anticipated savings or benefits from past or future rationalization plans in full or in part or within the time periods we expect. Failure to realize anticipated savings or benefits from our cost reduction actions could have a material adverse effect on a jointour business, financial condition, liquidity, results of operations and several basis.cash flows.

The Company has been advised that there is no arrangement or understanding among any one of the officers listed and any other persons pursuant to which he or she was elected as an officer. The executive officers are elected by the Board of Directors normally for a term of one year and/or until the election of their successors.

All properties relating to the Company's Cleveland, Ohio headquarters and manufacturing facilities are owned by the Company. Most of the Company's foreign subsidiaries own manufacturing facilities in the country where they are located. The Company believes that its existing properties are in good condition and are suitable for the conduct of its business.

In addition, the Company maintains operating leases for some manufacturing facilities, distribution centers and sales offices throughout the world. See Note 16 to the Company's consolidated financial statements for information regarding the Company's lease commitments.

The Company is subject, from time to time, to a variety of civil and administrative proceedings arising out of its normal operations, including, without limitation, product liability claims, regulatory claims and health, safety and environmental claims. Among such proceedings are the cases described below.

The principal raw materials essential to the Company's business are steel, electronic components, engines, brass, copper, silver, aluminum alloys and various chemicals, all of which are normally available for purchase in the open market.

Key economic measures relevant to the Company include industrial production trends, steel consumption, purchasing manager indices, capacity utilization within durable goods manufacturers and consumer confidence indicators. Key industries which provide a relative indication of demand drivers to the Company include steel, farm machinery and equipment, construction and transportation, fabricated metals, electrical equipment, ship and boat building, defense, truck manufacturing, energy and railroad equipment. Although these measures provide key information on trends relevant to the Company, the Company does not have available a more direct correlation of leading indicators which can provide a forward-looking view of demand levels in the markets which ultimately use the Company's welding products.

Key operating measures utilized by the operating units to manage the Company include orders, sales, inventory and fill-rates, all of which provide key indicators of business trends. These measures are reported on various cycles including daily, weekly and monthly depending on the needs established by operating management.

Key financial measures utilized by the Company's executive management and operating units in order to evaluate the results of its business and in understanding key variables impacting the current and future results of the Company include: sales; gross profit; selling, general and administrative expenses; operating income; earnings before interest and taxes; earnings before interest, taxes and bonus; net income; adjusted operating income; adjusted earnings before interest and income taxes, adjusted net income; adjusted diluted earnings per share; operating cash flows; and capital expenditures, including applicable ratios such as return on invested capital and average operating working capital to sales. These measures are reviewed at monthly, quarterly and annual intervals and compared with historical periods, as well as objectives established by the Board of Directors of the Company.

The following table shows the Company's results of operations:

The Company reviews Adjusted operating income, Adjusted net income, and Adjusted diluted earnings per share and Return on invested capital, all non-GAAP financial measures, in assessing and evaluating the Company's underlying operating performance. These non-GAAP financial measures exclude the impact of special items on the Company's reported financial results. Non-GAAP financial measures should be read in conjunction with the generally accepted accounting principles in the United States ("GAAP") financial measures, as non-GAAP measures are a supplement to, and not a replacement for, GAAP financial measures. From time to time management evaluates and discloses to investors the non-GAAP measure Free cash flow ("FCF").  FCF is defined as Net cash provided by operating activities less Capital expenditures.

The following table presents a reconciliation of Operating income as reported to Adjusted operating income:

Special items included in Operating income during 2014 include net rationalization and asset impairment charges primarily consisting of non-cash asset impairment charges of $32,742 offset by gains of $3,930 related to the sale of assets. Special items for 2014 also include Venezuelan remeasurement losses of $21,133 related to the adoption of a new foreign exchange mechanism in the first quarter.mechanism.

The following table presents reconciliations of Net income and Diluted earnings per share as reported to Adjusted net income and Adjusted diluted earnings per share:

The Company's cash flow from operations can be cyclical. Operational cash flow is a key driver of liquidity, providing cash and access to capital markets. In assessing liquidity, the Company reviews working capital measurements to define areas for improvement. Management anticipates the Company will be able to satisfy cash requirements for its ongoing businesses for the foreseeable future primarily with cash generated by operations, existing cash balances, borrowings under its existing credit facilities and raising debt in capital markets.

The following table reflects changes in key cash flow measures:
