BUSINESSAs used in this Annual Report on Form 10-K for the fiscal year ended December 31, 2017, the terms "ACCO Brands," "ACCO," the "Company," "we,""us," and "our" refer to ACCO Brands Corporation, a Delaware corporation incorporated in 2005, and its consolidated domestic and international subsidiaries.For a description of certain factors that may have had, or may in the future have, a significant impact on our business, financial condition or results ofoperations, see "Item 1A. Risk Factors."Overview of the CompanyACCO Brands is a designer, marketer and manufacturer of recognized consumer and end-user demanded brands used in businesses, schools, and homes.Our widely known brands include AT-A-GLANCE®, Derwent®, Esselte®, Five Star®, GBC®, Hilroy®, Kensington®, Leitz®, Marbig®, Mead®, NOBO®,Quartet®, Rapid®, Rexel®, Swingline®, Tilibra® and Wilson Jones®. More than 80% of our net sales come from brands that occupy the number one or numbertwo positions in the select product categories in which we compete. We distribute our products through a wide variety of retail and commercial channels toensure that our products are readily and conveniently available for purchase by consumers and other end-users, wherever they prefer to shop. These channelsinclude mass retailers, e-tailers, discount, drug/grocery and variety chains; warehouse clubs; hardware and specialty stores; independent office productdealers; office superstores; and contract stationers. Our products are sold primarily in the U.S., Europe, Australia, Canada, Brazil and Mexico. For the yearended December 31, 2017, approximately 55% of our sales were outside the U.S.; up from 43% in 2016. This increase was the result of the Esselte andPelikan Artline acquisitions, which further extended our geographic reach. For further information on the acquisitions see "Note 3. Acquisitions" to theconsolidated financial statements contained in Part II, Item 8. of this report and "Part II. Item 7. Management's Discussion and Analysis of FinancialCondition and Results of Operations."Over the past several years we have transformed our business by: divesting certain non-core commercially-oriented product lines; acquiring companieswith consumer and end-user demanded brands, and continuing to diversify our distribution channels. In 2012, we acquired the Mead Consumer and OfficeProducts business ("Mead C&OP"), which substantially increased our presence in North America and Brazil in school and calendar products with well-knownconsumer brands. In 2016, we purchased the remaining equity interest in Pelikan Artline from our joint venture partner, which enhanced our competitiveposition in school and business products in Australia and New Zealand and added new consumer categories, including writing instruments and janitorialsupplies. In early 2017, we acquired Esselte Group Holdings AB ("Esselte"), which more than doubled our presence in Europe and added several iconicbusiness brands, a significant base of independent dealer customers, and a new product category of do-it-yourself hardware tools. Together these threeacquisitions have meaningfully expanded our portfolio of well-known end-user demanded brands, enhanced our competitive position from both a productand channel perspective, and added scale to our business operations.Today our Company is a global enterprise focused on developing innovative branded consumer products for use in businesses, schools and homes. Webelieve our leading product category positions provide the scale to enable us to invest in marketing and product innovation to drive profitable growth. Weexpect to derive much of our growth, over the long term, in faster-growing emerging geographies such as Latin America and parts of Asia, the Middle Eastand Eastern Europe, which exhibit stronger demand for our product categories than in developed markets. In all of our markets we see opportunities to growsales through share gains, channel expansion and innovative products. We plan to supplement organic growth globally with strategic acquisitions in bothexisting and adjacent product categories.Reportable SegmentsACCO Brands has three operating business segments each of which is comprised of different geographic regions. Each of the Company's three operatingsegments designs, markets, sources, manufactures and sells recognized consumer and end-user demanded brands used in businesses, schools and homes.Product designs are tailored based on end-user preferences in each geographic region.1Our product categories include storage and organization; stapling; punching; laminating, binding and shredding machines and related consumablesupplies; whiteboards; notebooks; calendars; computer accessories; and do-it-yourself tools, among others. Our portfolio of consumer and end-userdemanded brands includes both globally and regionally recognized brands.Operating Segment Geographic Regions Primary BrandsACCO Brands North America United States and Canada AT-A-GLANCE®, Five Star®, GBC®, Hilroy®, Kensington®,Mead®, Quartet®, and Swingline® ACCO Brands EMEA Europe, Middle East and Africa Derwent®, Esselte®, GBC®, Kensington®, Leitz®, NOBO®,Rapid®, and Rexel® ACCO Brands International Australia, Latin America and Asia-Pacific Artline®, GBC®, Kensington®, Marbig®, Quartet®, Rexel®,Tilibra®, and Wilson Jones®Sales Percentage by Operating Segment 2017 2016 2015ACCO Brands North America 51% 65% 68%ACCO Brands EMEA 28% 11% 13%ACCO Brands International 21% 24% 19% 100% 100% 100%ACCO Brands North AmericaThe ACCO Brands North America segment is comprised of the United States and Canada where the Company is a leading branded supplier of consumerand business products under brands such as AT-A-GLANCE®, Five Star®, GBC®, Hilroy®, Kensington®, Mead®, Quartet®, and Swingline®. The ACCO BrandsNorth America segment designs, sources or manufactures and distributes school notebooks, calendars, whiteboards, storage and organization products (suchas three-ring binders, sheet protectors and indexes), stapling, punching, laminating, binding and shredding products, and computer accessories, among others,which are primarily used in schools, homes and businesses. The majority of revenue in this segment is related to consumer and home products and isassociated with the "back-to-school" season and calendar year-end purchases; we expect sales of consumer products to become an increasingly greaterpercentage of our revenue as they are faster growing than most business-related products.ACCO Brands EMEAThe ACCO Brands EMEA segment is comprised of Europe, the Middle East and Africa, where the Company is a leading branded supplier of consumerand business products under brands such as Derwent®, Esselte®, GBC®, Kensington®, Leitz®, NOBO®, Rapid®, and Rexel®.

Information onBusiness Segments" to the consolidated financial statements contained in Part II, Item 8. of this report.2CustomersACCO Brands markets and sells its strong multi-product offering broadly and is not dependent on any one channel. Our products are sold through allrelevant channels, namely retailers, including: mass retailers; e-tailers; discount, drug/grocery and variety chains; warehouse clubs; hardware and specialtystores; independent office product dealers; office superstores; and contract stationers. We also sell directly to commercial and consumer end-users throughour e-commerce platform and our direct sales organization. Changes in consumer buying patterns over the past several years have resulted in increasedconsumer purchases of our products through mass retailers and e-tailers. Increased sales through retail and e-tail channels have partially mitigated the impactof lower traffic and sales experienced by the traditional office products suppliers and wholesaler channels.Our top ten customers accounted for 44% of net sales for the year ended December 31, 2017. During 2017, no customer exceeded 10% of our net sales.Sales to Staples amounted to approximately 14% of net sales for each of the years ended December 31, 2016 and 2015. Sales to Walmart amounted toapproximately 10% of net sales for the year ended December 31, 2016. Sales to Office Depot amounted to approximately 10% of net sales for the year endedDecember 31, 2015.CompetitionWe operate in a highly competitive environment characterized by low-cost competitors, large, sophisticated customers, low barriers to entry, andcompetition from a wide range of products and services (including private label). ACCO Brands competes with numerous branded consumer productsmanufacturers as well as numerous private label suppliers and importers, including many of our customers who import their own private label productsdirectly from foreign sources. Examples of branded competitors to ACCO Brands include Bi-Silque, Blue Sky, CCL Industries, Dominion Blueline, Fellowes,Hamelin, Herlitz, LSC Communications, Newell Rubbermaid, Novus, Smead, Spiral Binding and Stanley Black and Decker, among others.The Company meets its competitive challenges by creating and maintaining leading brands and differentiated and innovative products that deliversuperior value, performance and benefits to consumers. Our products are sold to consumers and end-users through diverse distribution channels deliveringsuperior customer services. We further meet consumer needs by developing, producing and procuring products at a competitive cost, which are pricedattractively. The Company’s management also believes that its experience at successfully managing a complex, highly seasonal business is a competitiveadvantage.Product DevelopmentOur strong commitment to understanding our consumers and designing products that fulfill their needs drives our product development strategy, whichwe believe is and will continue to be a key contributor to our success. Our products are developed from a strong understanding of consumer needs by our ownresearch and development team or through partnership initiatives with inventors and vendors. Costs related to consumer and product research when paiddirectly by ACCO Brands are included in marketing costs and research and development expenses, respectively. Research and development expensesamounted to $23.5 million, $21.0 million and $20.0 million for the years ended December 31, 2017, 2016 and 2015, respectively. As a percentage of sales,research and development expenses were 1.2%, 1.3% and 1.3% for the years ended December 31, 2017, 2016 and 2015, respectively.We consistently review our business units and product offerings, assess their strategic fit, and seek opportunities to invest in new products andadjacencies as well as to rationalize our product offerings. The criteria we use in assessing strategic fit or investment opportunities include: the ability toincrease sales for the Company; the ability to create strong, differentiated products and brands; the importance of the product category to key customers; therelationship with existing product lines; the importance to the market; the actual and potential impact on our operating performance; and the value to ACCOBrands versus an alternative owner.Marketing and Demand GenerationWe support our brands with a significant investment in targeted marketing, advertising and consumer promotions, which increase brand awareness andhighlight the innovation and differentiation of our products. We work with third party vendors, such as Nielsen, NPD Group, GfK SE and Kantar Group, tocapture and analyze consumer buying habits and product trends. We also use our deep consumer knowledge to develop effective marketing programs,strategies and merchandising activities.3Raw MaterialsThe primary materials used in the manufacturing of many of our products are paper, plastics, resin, polyester and polypropylene substrates, steel, wood,aluminum, melamine, zinc and cork. These materials are available from a number of suppliers, and we are not dependent upon any single supplier for any ofthese materials. Based on our experience, we believe that adequate quantities of these materials will be available in the foreseeable future.SupplyOur products are either manufactured or sourced to ensure that we supply our customers with quality products, innovative solutions and attractivepricing as well as convenient customer service. We have built a customer-focused business model with a flexible supply chain to ensure that these factors areappropriately balanced. Using a combination of manufacturing and third-party sourcing also enables us to reduce our costs and effectively manage ourproduction assets by lowering capital investment and working capital requirements. Our overall strategy is to manufacture locally those products that wouldincur a relatively high freight and/or duty expense or that have high customer service needs and source through third-parties those products, which requirehigher direct labor to produce. We also look for opportunities to leverage our manufacturing facilities to improve operating efficiencies as well as customerservice. We currently manufacture approximately half of our products locally where we operate, and source the remaining half in lower cost countries,primarily China, but also other Far Eastern countries and Eastern Europe.SeasonalityHistorically, our business has experienced higher sales and earnings in the third and fourth quarters of the calendar year and we expect these trends tocontinue. Two principal factors contribute to this seasonality: (1) we are a major supplier of products related to the back-to-school season, which occursprincipally from June through September for our North American business and from November through February for our Australian and Brazilian businesses;and (2) several product categories we sell lend themselves to calendar year-end purchase timing, including planners, paper organization and storage products(including bindery) and Kensington® computer accessories, which have higher sales in the fourth quarter driven by traditionally strong fourth-quarter sales ofpersonal computers and tablets. As a result, we have generated, and expect to continue to generate, most of our earnings in the second half of the year andmuch of our cash flow in the first, third and fourth quarters as receivables are collected.For further information on the seasonality of net sales and earnings, see "Note 19. Quarterly Financial Information (Unaudited)" to the consolidatedfinancial statements contained in Part II, Item 8. of this report.Intellectual PropertyOur products are marketed under a variety of trademarks. Some of our more significant trademarks include ACCO®, AT-A-GLANCE®, Derwent®,Esselte®, Five Star®, GBC®, Hilroy®, Kensington®, Leitz®, Marbig®, Mead®, NOBO®, Quartet®, Rapid®, Rexel®, Swingline®, Tilibra®, and Wilson Jones®.We own rights to these trademarks in various countries throughout the world. We protect these marks as appropriate through registrations in the U.S. andother jurisdictions. Depending on the jurisdiction, trademarks are generally valid as long as they are in use or their registrations are properly maintained andthey have not been found to have become generic. Registrations of trademarks can also generally be renewed indefinitely as long as the trademarks are in use.We also own numerous patents worldwide. While we consider our portfolio of trademarks, patents, proprietary trade secrets, technology, know-how processes,and related intellectual property rights to be material to our operations in the aggregate, the loss of any one trademark, patent or a group of related patentswould not have a material adverse effect on our business as a whole.Environmental MattersWe are subject to national, state, provincial and/or local environmental laws and regulations concerning the discharge of materials into the environmentand the handling, disposal and clean-up of waste materials and otherwise relating to the protection of the environment. This includes environmental laws andregulations that affect the design and composition of certain of our products. It is not possible to quantify with certainty the potential impact of actionsregarding environmental matters, particularly remediation and other compliance efforts that we may undertake in the future. In the opinion of management,compliance with the present environmental protection laws, before taking into account estimated recoveries from third parties, will not have a materialadverse effect upon our capital expenditures, financial condition and results of operations or competitive position.4EmployeesAs of December 31, 2017, we had approximately 6,620 full-time and part-time employees. There have been no strikes or material labor disputes at anyof our facilities during the past five years. We consider our employee relations to be good.5Executive Officers of the CompanyThe following sets forth certain information with regard to our executive officers as of February 28, 2018 (ages are as of December 31, 2017).Mark C.

RISK FACTORSThe factors that are discussed below, as well as the matters that are generally set forth in this Annual Report on Form 10-K and the documentsincorporated by reference herein, could materially and adversely affect the Company’s business, results of operations and financial condition.A limited number of large customers account for a significant percentage of our net sales, and a substantial reduction in sales to or the consolidationof one or more of these customers could adversely impact our results of operations.Our top ten customers accounted for 44% of our net sales for the year ended December 31, 2017. The loss of, or a significant reduction in sales to, one ormore of our top customers, or significant changes to the terms on which we sell our products to our top customers, could have a material adverse effect on ourbusiness, results of operations and financial condition.When our larger customers resist our efforts to increase prices, delist our products or reduce the shelf space allotted to our products, or demand lowerpricing, increased promotional programs, longer payment terms or specifically tailored products, our sales and margins may be adversely effected. Othersignificant retail customers might also adopt these tactics in their dealings with us in response to the significant growth in online retailing for consumerproducts, which is outpacing the growth of traditional retail channels. Larger customers also generally have the scale to develop supply chains that permitthem to change their buying patterns, operate with reduced inventories or develop and market their own private label and other economy brands that competewith some of our products, all of which negatively impacts our sales and margins.Office superstores, wholesale and retail customers in Europe, the U.S. and our other major markets face increasing competition. In response theycontinue to consolidate or form buying alliances, resulting in fewer, larger customers with whom we can conduct business. Additionally, certain of them face,or in the future may face, financial difficulties. Continued consolidation among one or a few large retailers in a particular country or region increases the riskthat if any one of them substantially reduces its purchases of our products, we may be unable to find a sufficient number of other retail outlets for our productsto sustain the same level of sales and margins. In 2013, two of our large U.S. customers, Office Depot and OfficeMax, merged. Another large customer, Staples,along with Office Depot also continue to sell off parts of their non-U.S. business to private equity firms. Historically, consolidation of our customers or theirsale to private equity firms have had a material impact on our sales and margins. Further, the declining financial health of one or more of our large customersmay result in a significant loss or reduction in sales to that customer.The economic climate in some of the countries in which we operate is volatile. A slowing economy in our key markets or changes in consumer buyinghabits could adversely affect the financial health of one or more of our large customers, which in turn could have an adverse effect on our results of operationsand financial condition. The sell-through of our products by our customers is dependent in part on high quality merchandising and an appealing storeenvironment to attract consumers, which requires continuing investments by our customers. Large customers that experience financial difficulties may fail tomake such investments or delay them, resulting in lower sales and orders for our products.Sales of our products may be adversely affected by issues that affect consumer discretionary spending and/or consumer spending decisions duringperiods of economic uncertainty or weakness.Our business depends on consumer discretionary spending, and as a result, our results are highly dependent on consumer and business confidence andthe health of the economies in the countries in which we operate. Consumer spending is affected by many factors outside of the Company’s control,including general economic conditions, consumer disposable income levels, consumer confidence levels, the availability, cost and level of consumer debt,the costs of basic necessities and other goods and the effects of the weather or natural disasters. Additionally, during periods of economic uncertainty orweakness, we tend to see our reseller customers reduce inventories as the demand for our products decrease as consumers forgo certain purchases altogether orswitch to private label and other branded and/or generic products that compete on price and quality. Decreases in consumer demand for our products canresult in the need to spend more on promotional activities. Overall, adverse changes in economic conditions or sustained periods of economic uncertainty orweakness could negatively affect our earnings and have an adverse effect on our business, results of operations, cash flow and financial condition.7The Company has foreign currency translation and transaction risks that may materially adversely affect the Company’s results of operations,financial condition and liquidity.Approximately 55% of our net sales for the fiscal year ended December 31, 2017 were transacted in a currency other than the U.S. dollar. Thefluctuations in the foreign currency rates relative to the U.S. dollar can cause transaction, translation, and other losses, which could negatively impact oursales and profitability. We also source approximately half of our products from China and other Far Eastern countries using U.S. dollars. The strengthening ofthe U.S. dollar against foreign currencies ordinarily has a negative impact on the Company’s reported sales and operating margins, and conversely, theweakening of the U.S. dollar against foreign currencies ordinarily has a positive impact.When our cost of goods increases due to a strengthening in the U.S. dollar against the local foreign currency, we will seek to raise prices in our foreignmarkets in an effort to recover the lost margin. Due to competitive pressures and the timing of these price increases relative to the changes in the foreigncurrency exchange rates, it is often difficult to increase prices fast enough to fully offset the cumulative impact of the foreign-exchange-related inflation ofour cost of goods sold in these markets. From time to time, we may also use hedging instruments to mitigate transactional exposure to changes in foreigncurrencies. The effectiveness of our hedges in part depends on our ability to accurately forecast future cash flows, which is particularly difficult duringperiods of uncertain demand for our products and services and highly volatile exchange rates. Further, hedging activities may only offset a portion, or none atall, of the material adverse financial effects of unfavorable movements in foreign exchange rates over the limited time the hedges are in place and we mayincur significant losses from hedging activities due to factors such as demand volatility and currency fluctuations.Our primary exposure to local currency movements is in Europe (the Euro, the Swedish krona and the British pound), Australia, Canada, Brazil, andMexico. Government actions such as currency devaluations, foreign exchange controls, price or profit controls, and a government take-over, could furtheradversely impact foreign currency exchange rates and the Company’s business, results of operations, cash flows, and financial condition.Challenges related to the highly competitive business environments in which we operate could have a material adverse effect on our business, resultsof operations and financial condition.We operate in a highly competitive environment characterized by low-cost competitors; large, sophisticated customers; low barriers to entry; andcompetition from a wide range of products and services (including private label products and electronic and digital products and services that can replace orrender certain of our products obsolete). ACCO Brands competes with numerous branded consumer products manufacturers as well as numerous private labelsuppliers and importers, including many of our customers who import their own private label products directly from foreign sources. Many of our competitorshave strong, sought-after brands. They also have the ability to manufacture products locally at a lower cost or source them from other countries with lowerproduction costs both of which can give them a competitive advantage in terms of price under certain circumstances. In addition, retail space devoted to ourproduct categories is limited and, as a result of competitive pressures, many of our customers are closing retail locations, reducing the size of their retail storesand diversifying their product offerings further reducing the available retail space devoted to our products.As a result, our business is likely to be affected by actions: (1) by our customers to increase their purchases of private label products or otherwisechange product assortments; (2) by current and potential competitors to increase investment in product and brand development, lower prices, take advantageof low entry barriers to expand their production, or move production to countries with lower production costs; and (3) by consumers and other end-users touse lower-priced or alternative products. Any such actions could result in lower sales and margins and adversely affect our business, results of operations andfinancial condition.Our success depends partially on our ability to continue to develop and market innovative products that meet our consumer demands, including priceexpectations.Our competitive position depends on our ability to successfully invest in innovation and product development. That success will depend, in part, onour ability to anticipate and develop and market products that appeal to the changing needs and preferences of our consumers. We could focus our efforts andinvestment on new products that ultimately are not accepted by consumers. Likewise, our failure to offer innovative products that meet consumer and end-user demand could compromise our competitive position and adversely affect our sales, profitability and results of operation.8Our strategy is partially based on growth through acquisitions and the expansion of our product assortment into new and adjacent productcategories that are experiencing higher growth rates. Failure to properly identify, value, manage and integrate acquisitions or to expand into adjacentcategories may materially impact our business, results of operations and financial condition.Our growth strategy includes continued focus on mergers and acquisitions. We are focused on acquiring companies that are either in our existingproduct categories or geographic markets, which enhance our ability to compete effectively or that have the potential to accelerate our growth or our entryinto adjacent product categories.We may not be successful in identifying suitable acquisition opportunities, prevailing against competing potential acquirers, negotiating appropriateacquisition terms, obtaining financing, completing proposed acquisitions, integrating acquired businesses or expanding in new markets or productcategories. In addition, an acquisition may not perform as anticipated, be accretive to earnings or prove to be beneficial to our operations and cash flow. If wefail to effectively identify, value, consummate, manage and integrate any acquired company, we may not realize the potential growth opportunities orachieve the financial results anticipated at the time of its acquisition.An acquisition could also adversely impact our operating performance as a result of the issuance of acquisition-related debt, pre-acquisition assumedliabilities, undisclosed facts about the business, acquisition expense and the amortization of acquired assets or possible future impairments of goodwill orintangible assets associated with the acquisition.To the extent acquisitions increase our exposure to emerging markets, the risks associated with doing business in these markets will increase. See also "-Growth in emerging geographies may be difficult to achieve and exposes us to financial, operational, regulatory and compliance and other risks notpresent or not as prevalent as in more established markets."Additionally, part of our strategy is to expand our product assortment into new and adjacent product categories with a higher growth profile. There canbe no assurance that we will successfully execute these strategies. If we are unable to successfully increase sales by expanding our product assortment, ourbusiness, results of operations and financial condition could be adversely affected.We may face challenges with integrating acquisitions and achieving the financial and other results anticipated at the time of acquisition, includingthe planned synergies.We may face challenges in integrating our acquisitions, including the Pelikan Artline and Esselte acquisitions, with our existing operations. Thesechallenges may include, among other things: integrating the business cultures; possible difficulties in retaining key employees and key customers; and thedifficulty of integrating the acquired business's finance, accounting and other business systems without negatively impacting our internal control overfinancial reporting and our disclosure controls and procedures.The process of integrating operations also could cause an interruption of, or loss of momentum in, the activities of one or more of our businesses.Members of our senior management may need to devote considerable amounts of time to the integration process. If our senior management is not able toeffectively manage the integration processes, or if any significant business activities are interrupted as a result of the integration process, our business andfinancial results could suffer.Additionally, we generally expect that we will realize synergy cost savings and other financial and operating benefits from our acquisitions. Oursuccess in realizing these synergy savings and other financial and operating benefits, and the timing of this realization depends on the successful integrationof the business operations of the acquired company. We cannot predict with certainty if or when these synergy savings and other benefits will occur, or theextent to which we will be successful.Finally, the integration of any acquisition will involve changes to, or implementation of critical information technology systems, modifications to ourinternal control systems, processes and accounting and financial systems, and the establishment of disclosure controls and procedures and internal controlover financial reporting necessary to meet our obligations as a public company. Failure to successfully complete any of these tasks could adversely affect ourinternal control over financial reporting, our disclosure controls and procedures and our ability to effectively and timely report our financial results. If we areunable to accurately report our financial results in a timely manner and establish internal control over financial reporting and disclosure controls andprocedures that are effective; our business, results of operation and financial condition; investor, supplier and customer confidence in our reported financialinformation; the market perception of our Company and/or the trading price of our common stock could be materially and adversely affected.9We rely extensively on information technology systems to operate, transact and otherwise manage our business. Any material failure, inadequacy, orinterruption of that technology or its supporting infrastructure could materially adversely affect our business, results of operations and financialcondition.We rely extensively on our information technology systems, many of which are outsourced to third-party service providers. We depend on thesesystems and our third-party service providers to effectively manage our business and execute the production, distribution and sale of our products as well asto manage and report our financial results and run other support functions. Although we have implemented service level agreements and have establishedmonitoring controls, if our third-party service providers fail to perform their obligations in a timely manner or at satisfactory levels, our business could suffer.Additionally, our failure to properly maintain and successfully upgrade or replace any of these systems, especially our enterprise resource planning systems(including our financial systems), so that they operate effectively could disrupt service to our customers or negatively impact our ability to report ourfinancial results in a timely and accurate manner.Our information technology general controls are an important element of our internal control over financial reporting and our disclosure controls andprocedures. Failure to successfully execute our information technology general controls could adversely impact the effectiveness of our internal control overfinancial reporting and our disclosure controls and procedures and impair our ability to accurately and timely report our financial results.If services to our customers are negatively impacted by the failure of our information systems, if we are unable to accurately and timely report ourfinancial results, or conclude that we do not have effective internal control over financial reporting and effective disclosure controls and procedures, it coulddamage our reputation and adversely affect our business, results of operations and financial condition.Security breaches could compromise our confidential and proprietary information as well as personally identifiable information we hold and exposeus to operational and legal risks which could cause our business and reputation to suffer and materially adversely affect our results of operations.We maintain information necessary to conduct our business in digital form, which is stored in data centers and on our networks and third-party cloudservices, including confidential and proprietary information as well as personally identifiable information regarding our customers and employees. Datamaintained in digital form is subject to the risk of intrusion, tampering and theft. Our information technology and infrastructure may be vulnerable to attacksby hackers or breached due to employee error, malfeasance or other disruptions.We maintain systems designed to prevent such intrusion, tampering and theft. The development and maintenance of these systems is costly andrequires ongoing monitoring and updating as technologies change and efforts by hackers to overcome security measures become more sophisticated. Further,we obtain assurances from third parties to whom we provide confidential, proprietary and personally identifiable information regarding the sufficiency oftheir security procedures and, where appropriate, assess the protections employed by these third parties.Despite these efforts, the possibility of intrusion, tampering and theft cannot be eliminated entirely. The techniques used to obtain unauthorized access,disable or degrade service, or sabotage systems change frequently and often are not recognized until launched against a target. Additionally, there can be noassurance that the actions we and our third party providers are taking and will continue to take will prevent a breach of, or attack on the information systemswhich house our confidential, proprietary and personally identifiable information. Any such breach or attack could compromise our network, the network of athird party to whom we have disclosed confidential, proprietary or personally identifiable information, a data center where we have stored such informationor a third-party cloud service provider, and the information stored there could be accessed, publicly disclosed, lost or stolen.Any such intrusion, tampering or theft and any resulting disclosure or other loss of such information could result in a disruption to our informationtechnology infrastructure, interruption of our business operations, violation of applicable privacy and other laws or standards, significant legal and financialexposure beyond the scope or limits of any insurance coverage, increased operating costs associated with remediation activities, and a loss of confidence inour security measures, all of which could harm our reputation with our customers, end-users, employees and other stakeholders and adversely affect ourresults of operation. Contractual provisions with third parties, including cloud service providers, may limit our ability to recover these losses.10Growth in emerging geographies may be difficult to achieve and exposes us to financial, operational, regulatory and compliance and other risks notpresent or not as prevalent as in more established markets.A portion of our sales are derived from emerging markets such as Latin America and parts of Asia, the Middle East, Africa and Eastern Europe.Moreover, the profitable growth of our business in emerging markets, through both organic investments and through acquisitions, is a key element to ourlong-term growth strategy.Emerging markets generally involve more financial, operational and regulatory and compliance risks than more mature markets. In some cases,emerging markets have greater political and economic volatility, greater vulnerability to infrastructure and labor disruptions, are more susceptible tocorruption and have different laws and regulations. Further, these emerging markets are generally more remote from our headquarter's location and havedifferent cultures which may make it be more difficult to impose corporate standards and procedures and the extraterritorial laws of the U.S. and otherjurisdictions, including the U.S. Foreign Corrupt Practices Act , the U.K. Bribery Act and other similar laws. Negative or uncertain political climates andmilitary disruptions in developing and emerging markets could also adversely affect us. Further, weak or corrupt legal systems may affect our ability toprotect and enforce our intellectual property, contractual and other rights.As we seek to expand and grow in these emerging markets, we increase our exposure to these financial, operational and regulatory and compliance risksas well as legal and other risks, including currency transfer restrictions, the impact of currency fluctuations, hyperinflation or devaluation, changes ininternational trade and tax policies and regulations (including import and export restrictions), the lack of well-established or reliable legal systems,corruption, adverse economic conditions, political actions or instability, terrorism and civil unrest. Likewise, our overall cost of doing business increases dueto the costs of compliance with complex and numerous foreign and U.S. laws and regulations.If we are unable to successfully expand into emerging markets, profitably grow our existing emerging market businesses, achieve the return on capitalwe expect as a result of our investments, or effectively manage the risks inherent in our growth strategy in these markets, our business, results of operationsand financial condition could be adversely affected.The effects of the U.S. Tax Cuts and Jobs Act on our business have not yet been fully analyzed and could have an adverse effect on our net income andcash flows.On December 22, 2017, the Tax Cuts and Jobs Act (the "U.S. Tax Act") was signed into law in the U.S. The U.S. Tax Act includes, among other things,changes to U.S. federal tax rates, imposing significant additional limitations on the deductibility of interest, allowing for the expensing of capitalexpenditures, the migration from a "worldwide" system of taxation to a modified territorial system, and the use of certain border adjustments. Any benefitsassociated with lower U.S. corporate tax rates could be reduced or outweighed by other tax changes adverse to our business or operations, such as new oradditional taxes imposed on earnings and/or reinvested earnings of our foreign subsidiaries. Additionally, the manner in which the U.S. Tax Act will beinterpreted and enforced is still evolving so it is not possible to fully analyze its ultimate impact on the Company. The aggregate impact of such legislationwhen fully implemented could have a material adverse impact on our cash flows and results of operations.Changes to current policies by the U.S. government could materially adversely affect our business.We anticipate possible changes to current policies by the U.S. government that could affect our business, including increased import tariffs or quotasand other changes in U.S. trade relations with other countries (e.g., Mexico and China). These changes could increase our costs in certain markets requiring usto find alternative suppliers or to increase prices. This may cause our customers to find alternative sourcing. There can be no assurance that the Company willbe able to locate alternative suppliers for its products at acceptable costs in a timely manner. In response to these changes, other countries may change theirown policies on business and foreign investment in companies. Additionally, it is possible that U.S. policy changes and uncertainty about policy couldincrease the volatility of currency exchange rates, which could adversely impact our results of operations and financial condition.Litigation or legal proceedings could expose us to significant liabilities and damage our reputation.We are party to various lawsuits and regulatory proceedings, primarily related to alleged patent infringement and employee terminations as well asother claims incidental to our business. In addition, we may be unaware of third party claims of intellectual property infringement relating to our technology,brands or products and we may face other claims related to business operations. Any litigation regarding patents or other intellectual property could be costlyand time-consuming and might require us to pay monetary damages or enter into costly license agreements. We also may be subject to injunctions againstdevelopment and sale of certain of our products.11It is the opinion of management that (other than the Brazilian Tax Assessment described below) the ultimate resolution of currently outstanding matterswill not have a material adverse effect on our financial condition, results of operations or cash flow. However, there is no assurance that we will ultimately besuccessful in our defense of any of these matters or that an adverse outcome in any matter will not negatively affect our results of operations, financialcondition or cash flow. Further, future claims, lawsuits and legal proceedings could materially and adversely affect our business, reputation, results ofoperations and financial condition.In connection with our May 1, 2012 acquisition of the Mead Consumer and Office Products business ("Mead C&OP"), we assumed all of the taxliabilities for the acquired foreign operations including Tilibra Produtos de Papelaria Ltda. ("Tilibra"). In December of 2012, the Federal Revenue Departmentof the Ministry of Finance of Brazil ("FRD") issued a tax assessment (the "Brazilian Tax Assessment") against Tilibra, which challenged the tax deduction ofgoodwill from Tilibra's taxable income for the year 2007 (the "First Assessment"). A second assessment challenging the deduction of goodwill from Tilibra'staxable income for the years 2008, 2009 and 2010 was issued by FRD in October 2013 (the "Second Assessment"). Tilibra is disputing both of the taxassessments.Recently, the final administrative appeal of the Second Assessment was decided against the Company. We intend to challenge this decision in court inearly 2018. In connection with the judicial challenge, we may be required to post security to guarantee payment of the Second Assessment, which represents$24.6 million of the current reserve, should we not prevail. The First Assessment is still being challenged through established administrative procedures.We believe we have meritorious defenses and intend to vigorously contest these matters; however, there can be no assurances that we will ultimatelyprevail. The ultimate outcome will not be determined until the Brazilian tax appeal process is complete, which is expected to take a number of years. Inaddition, Tilibra's 2012 tax year remains open and subject to audit, and there can be no assurances that we will not receive an additional tax assessmentregarding the goodwill for 2012. The time limit for issuing an assessment for 2011 expired in January 2018 and we did not receive an assessment. The timelimit for issuing an assessment for 2012 will expire in January 2019. If the FRD's initial position is ultimately sustained, the amount assessed wouldmaterially and adversely affect our cash flow in the year of settlement.Because there is no settled legal precedent on which to base a definitive opinion as to whether we will ultimately prevail, we consider the outcome ofthis dispute to be uncertain. Since it is not more likely than not that we will prevail, in 2012, we recorded a reserve in the amount of $44.5 million (atDecember 31, 2012 exchange rates) in consideration of this contingency, of which $43.3 million was recorded as an adjustment to the purchase price andwhich included the 2007-2012 tax years plus penalties and interest through December 2012. Included in this reserve is an assumption of penalties at 75%,which is the standard penalty. While there is a possibility that a penalty of 150% could be imposed in connection with the First Assessment, based on thefacts in our case and existing precedent, we believe the likelihood of a 150% penalty is not more likely than not as of December 31, 2017. We will continueto actively monitor administrative and judicial court decisions and evaluate their impact, if any, on our legal assessment of the ultimate outcome of our case.In addition, we will continue to accrue interest related to this contingency until such time as the outcome is known or until evidence is presented that we aremore likely than not to prevail. During the years ended December 31, 2017, 2016 and 2015, we accrued additional interest as a charge to current tax expenseof $2.2 million, $2.8 million and $2.7 million, respectively. At current exchange rates, our accrual through December 31, 2017, including tax, penalties andinterest is $38.7 million.Outsourcing the production of certain of our products, our information technology systems and other administrative functions could materiallyadversely affect our business, results of operations and financial condition.We outsource certain manufacturing functions to suppliers in China, other Asia-Pacific countries and Eastern Europe. Outsourcing of product designand production creates a number of risks, including decreased control over the engineering and manufacturing processes resulting in unforeseen productiondelays or interruptions, inferior product quality, loss or misappropriation of trade secrets and other performance issues, which could result in cost overruns,delayed deliveries or shortages. Additionally, we rely on our suppliers to ensure that our products meet our design and product content specifications, and allapplicable laws, including product safety, security, labor and environmental laws. We also expect our suppliers to conform to our and our customers’expectations with respect to product safety, product quality and social responsibility, be responsive to our audits and otherwise be certified as meeting ourand our customers’ supplier codes of conduct. Failure to meet any of these requirements may result in our having to cease doing business with a supplier orcease production at a particular facility. Substitute suppliers might not be available or, if available, might be unwilling or unable to offer products onacceptable terms or in a timely manner. Any of these circumstances could result in unforeseen production delays and increased costs and negatively affect ourability to deliver products and services to our customers, all of which could adversely affect our business, results of operations and financial condition.12Moreover, if one or more of our suppliers is unable or unwilling to continue to provide products of acceptable quality, at acceptable cost or in a timelymanner due to financial difficulties, insolvency or otherwise, or if customer demand for our products increases, we may be unable to secure sufficientadditional capacity from our current suppliers, or others, in a timely manner or on acceptable terms. Increases in import duties and tariffs could alsonegatively affect our cost of finished goods manufactured by our suppliers in China and other Asia-Pacific countries. Any of these events could result inunforeseen production delays and increased costs and negatively affect our ability to deliver our products and services to our customers, all of which couldadversely affect our business, results of operations and financial condition.We also outsource important portions of our information technology infrastructure and systems support to third party service providers. Outsourcing ofinformation technology services creates risks to our business, which are similar to those created by our product production outsourcing. If one or more of ourinformation technology suppliers is unable or unwilling to continue to provide services at acceptable cost due to financial difficulties, insolvency orotherwise, or if our third party service providers experience a security breach or disruptions in service, our business could be adversely affected.In addition, we outsource certain administrative functions, such as payroll processing and benefit plan administration to third party service providersand may outsource other functions in the future to achieve cost savings and efficiencies. If the service providers to which we outsource these functions do notperform effectively, we may not be able to achieve the expected cost savings and may have to incur additional costs to correct errors they make. Dependingon the function involved, such errors may lead to business disruption, processing inefficiencies or loss of, or damage to intellectual property, or harm toemployee morale.Continued declines in the use of certain of our products could adversely affect our business.A number of our products and brands consist of paper-based and related products. As use of technology-based tools rises worldwide, consumer demandfor traditional paper-based and related products, such as decorative calendars, planners, envelopes, ring binders and mechanical binding equipment, hasdeclined. The continued decline or an acceleration of the decline in the overall demand for any of the products we sell could adversely impact our business,results of operations and financial condition.Our business is subject to risks associated with seasonality, which could materially adversely affect our cash flow, results of operations and financialcondition.Historically, our business has experienced higher sales and earnings in the third and fourth quarters of the calendar year and we expect these trends tocontinue. Two principal factors contribute to this seasonality: (1) we are a major supplier of products related to the back-to-school season, which occursprincipally from June through September for our North American business and from November through February for our Australian and Brazilian businesses;and (2) several product categories we sell lend themselves to calendar year-end purchase timing, including planners, paper organization and storage products(including bindery) and Kensington® computer accessories, which have higher sales in the fourth quarter driven by traditionally strong fourth-quarter sales ofpersonal computers and tablets. As a result, we have generated, and expect to continue to generate, most of our earnings in the second half of the year andmuch of our cash flow in the first, third and fourth quarters as receivables are collected. If these typical seasonal increases in sales of certain products do notmaterialize or if sales of these product lines were to represent a larger overall percentage of our sales or profitability, it may have an outsized impact on ourbusiness that could adversely affect our cash flow, results of operations and financial condition.Our operating results can be adversely affected by changes in the cost or availability of raw materials, transportation, and other necessary suppliesand services.Pricing and availability of raw materials, transportation, and other necessary supplies and services used in our business can be volatile due to numerousfactors beyond our control, including general, domestic and international economic conditions, labor costs, production levels, competition, consumerdemand, and import duties and tariffs. This volatility can significantly affect our business, results of operations, and financial condition.Our success is dependent, in part, on our continued ability to reduce our exposure to increases in those costs through a variety of programs, includingperiodic purchases, future delivery purchases, long-term contracts, sales price adjustments and certain derivative instruments, while maintaining andimproving margins and category share. Also, we rely on third-party manufacturers as a source for many of our products. These manufacturers are also subjectto price volatility and labor cost and other inflationary pressures, which may, in turn, result in an increase in the amount the Company pays for sourcedproducts. During periods of rising raw material prices, there can be no assurance that the Company will be able to pass any portion of such increases on tocustomers. Conversely, when raw material prices decline, customer demands for lower prices could result in lower sale prices and, to the extent the Companyhas existing inventory, lower margins. As a result, fluctuations in raw material prices could have a material adverse effect on the Company’s business, resultsof operations and financial condition.13The primary materials used in the manufacturing of many of our products are paper, plastics, resin, polyester and polypropylene substrates, steel, wood,aluminum, melamine, zinc and cork. Supply shortages for a particular type of material can delay production or cause increases in the cost of manufacturingthe Company’s products. This could have a material adverse effect on the Company’s business, results of operations and financial condition.The risks associated with our failure to comply with laws, rules and regulations and self-regulatory requirements that affect our business, and thecosts of compliance, as well as the impact of changes in such laws could materially adversely affect our business, reputation and results of operations.Our business is subject to national, state, provincial and/or local laws, rules and regulations as well as self-regulatory requirements in numerouscountries due to the nature of our operations and the products we sell. This, in turn, affects the way we conduct our business as well as our customers’expectations and requirements. Among others, laws and self-regulatory requirements in the following significant areas (and the rules and regulationspromulgated thereunder) affect our business and our current and prospective customers’ expectations:•Laws relating to the discharge and emission of certain materials and waste, and establishing standards for their use, disposal and management;•Laws governing content of toxic chemicals and materials in the products we sell;•Product safety laws;•International trade laws;•Privacy and data security laws;•Self-regulatory requirements regarding the acceptance, processing, storage and transmission of credit card data;•Laws governing the use of the internet, social media, advertising, endorsements and testimonials;•Anti-bribery and corruption laws;•Anti-money laundering laws; and•Competition laws.All of these legal frameworks are complex and may change frequently. For example, the European Union adopted the General Data ProtectionRegulation ("GDPR"), which will take effect in May 2018. The GDPR supersedes, and is more stringent than, the existing EU data protection directive.Capital and operating expenses required to establish and maintain compliance with all of these laws, rules and regulations and self-regulatory requirementscan be significant, and violations may result in substantial fines, penalties and civil damages as well as damage to our reputation. Any significant increase inour costs to comply with applicable legal and self-regulatory requirements, or liability arising from noncompliance, as well as changes in tariffs or dutiesassociated with the international transfer of goods could have an adverse effect on our business, results of operations and financial condition as well asdamage to our reputation.In addition, as we expand our business into emerging and new markets, we increase the number of legal and self-regulatory requirements with which weare required to comply, which increases the complexity and costs of compliance as well as the risks of noncompliance.The level of investment returns on pension and post-retirement plan assets and the actuarial assumptions used for valuation purposes could affect theCompany’s earnings and cash flows in future periods. Changes in government regulations could also affect the Company’s pension and post-retirementplan expenses and funding requirements.As of December 31, 2017, the Company had $276.2 million recorded as pension liabilities in its Consolidated Balance Sheet. The funding obligationsfor the Company’s pension plans are impacted by the performance of the financial markets, particularly the equity markets, and interest rates. Fundingobligations are determined by government regulations and are measured each year based on the value of assets and liabilities on a specific date. If thefinancial markets do not provide the long-term returns that are expected, the Company could be required to make larger contributions. The equity marketscan be, and recently have been, very volatile, and therefore the Company’s estimate of future contribution requirements can change dramatically in relativelyshort periods of time. Similarly, changes in interest rates and legislation enacted by governmental authorities can impact the timing and amounts ofcontribution requirements. An adverse change in the funded status of the plans could significantly increase the Company’s required contributions in thefuture and adversely impact its liquidity.Assumptions used in determining projected benefit obligations and the fair value of plan assets for the Company’s pension and post-retirement benefitplans are determined by the Company in consultation with outside actuaries. In the event that the Company determines that changes are warranted in theassumptions used, such as the discount rate, expected long-term rate of return on assets, expected health care costs, or mortality rates, the Company’s futurepension and post-retirement benefit expenses14could increase or decrease. Due to changing market conditions or changes in the participant population, the assumptions that the Company uses may differfrom actual results, which could have a significant impact on the Company’s pension and post-retirement liabilities and related costs and fundingrequirements.We also participate in a multi-employer pension plan for our union employees at our Ogdensburg, New York facility. The plan has reported significantunderfunded liabilities and declared itself in critical and declining status. As a result, the trustees of the plan adopted a rehabilitation plan in an effort toforestall insolvency. Our required contributions to this plan could increase due to the shrinking contribution base resulting from the insolvency, orwithdrawal of other participating employers, the inability or the failure of withdrawing participating employers to pay their withdrawal liability, lower thanexpected returns on pension fund assets, and other funding deficiencies. In the event that we withdraw from participation in the plan, we will be required tomake withdrawal liability payments for a period of 20 years or longer in certain circumstances. The present value of our withdrawal liability payments couldbe significant and would be recorded as an expense in our Consolidated Statements of Income and as a liability on our Consolidated Balance Sheets in thefirst year of our withdrawal.See also "Part II, Item 7. Critical Accounting Policies - Employee Benefit Plans" and "Note 5. Pension and Other Retiree Benefits" to the consolidatedfinancial statements contained in Part II, Item 8. of this report.Impairment of intangible assets could have a material adverse effect on our financial results.We have approximately $1.5 billion of goodwill and other specifically identifiable intangible assets as of December 31, 2017. Future events may occurthat could adversely affect the reported value, or fair value, of our intangible assets that would require impairment charges to our financial results. Suchevents may include, but are not limited to, strategic decisions made in response to changes in economic and competitive conditions, the impact of theeconomic environment on the Company’s sales and customer base, the unfavorable resolution of litigation, a material adverse change in the Company’srelationship with significant customers, or a sustained decline in the Company’s stock price. The Company continues to evaluate the impact of developmentsfrom its reporting units to assess whether impairment indicators are present. Accordingly, the Company may be required to perform impairment tests based onwhether or not indicators are present. In addition, the Company performs an impairment test on an annual basis in the second quarter, as required by GAAPwhether or not impairment indicators are present. See also "Part II, Item 7. Critical Accounting Policies - Intangible Assets," " - Goodwill" and "Note 9.Goodwill and Identifiable Intangible Assets" to the consolidated financial statements contained in Part II, Item 8. of this report.Our existing borrowing arrangements require us to dedicate a substantial portion of our cash flow to debt payments and limit our ability to engage incertain activities. If we are unable to meet our obligations under these agreements or are contractually restricted from pursuing activities or transactionsthat we believe are in our long-term best interests, our business, results of operations and financial condition could be materially adversely affected.As of December 31, 2017, we had $939.5 million of outstanding debt, which increased by approximately $326 million in early 2017 due to theborrowings to fund the acquisition of Esselte and related transaction expenses.Our debt service obligations require us to dedicate a substantial portion of our cash flow from operating activities to payments on our indebtedness,which reduces the availability of our cash flow to fund working capital, capital expenditures, research and product development efforts, potentialacquisitions and for other general corporate purposes. Our indebtedness also may increase our vulnerability to economic downturns and changing marketconditions and place us at a competitive disadvantage relative to competitors that have less debt. In addition, as of December 31, 2017, $538.9 million of ouroutstanding debt is subject to floating interest rates, which increases our exposure to fluctuations in interest rates.The terms of our debt agreements also limit our ability to engage in certain activities and transactions that may be in our and our stockholders' long-term interest. Among other things, the covenants and financial ratios and tests contained in our debt agreements restrict or limit our ability to incur additionalindebtedness, incur certain liens on our assets, issue preferred stock or certain disqualified stock, make restricted payments (including dividends and sharerepurchases), make investments, sell our assets or merge with other companies, and enter into certain transactions with affiliates. We are also required tomaintain specified financial ratios under certain circumstances and satisfy financial condition tests. Our ability to comply with these covenants and financialratios and tests may be affected by events beyond our control, and we may not be able to continue to meet those covenants, ratios and tests.Our ability to meet our debt obligations, including our financial covenants, and to refinance our existing indebtedness upon maturity, will depend uponour future operating performance, which will be affected by general economic, financial, competitive, regulatory, business and other factors. Breach of any ofthe covenants, ratios and tests contained in the agreements governing our15indebtedness, or our inability to pay interest on, or principal of, our outstanding debt as it becomes due, could result in an event of default, in which case ourlenders could declare all amounts outstanding to be immediately due and payable. If our lenders accelerate our indebtedness, or we are not able to refinanceour debts at maturity, our assets may not be sufficient to repay in full such indebtedness and any other indebtedness that would become due as a result of suchacceleration. If we then are unable to obtain replacement financing or any such replacement financing is on terms that are less favorable than theindebtedness being replaced, our liquidity, results of operations and financial condition would be adversely affected.Should any of the risks associated with our indebtedness be realized, our business, results of operations and financial condition could be adverselyaffected. See also "Part II, Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and CapitalResources."Should one of our large customers or suppliers experience financial difficulties or file for bankruptcy, our cash flows, results of operations andfinancial condition could be materially adversely affected.Our customer concentration increases our customer credit risk. If any of our larger customers were to face liquidity issues, become insolvent or file forbankruptcy, we could be adversely impacted due to not only a reduction in future sales but also delays in the payment of existing accounts receivablebalances. Such a result could adversely impact our cash flows, results of operations and financial condition.In addition, should one of our suppliers or third party service providers experience financial difficulties, our business, results of operations and financialcondition could be adversely affected.Our failure to comply with customer contracts may lead to fines or loss of business, which could adversely impact our revenue and results ofoperationsOur contracts with our customers include specific performance requirements. If we fail to comply with the specific provisions of our customer contracts,we could be subject to fines, suffer a loss of business or incur other penalties. If our customer contracts are terminated, if we fail to meet our contractualobligations, or if our ability to compete for new contracts is adversely affected, we could suffer a reduction in expected revenue and margins.Our inability to secure, protect and maintain rights to intellectual property could have an adverse impact on our business.We consider our intellectual property rights, particularly and most notably our trademarks and trade names, but also our patents, trade secrets, tradedress, copyrights and licensing agreements, to be an important and valuable part of our business. Our failure to obtain or adequately protect our intellectualproperty rights, or any change in law or other changes that serve to lessen or remove the current legal protections of our intellectual property, may diminishour competitiveness, dilute the value of our brands, cause confusion in the marketplace and materially impact our sales and profitability.Product liability claims, recalls or regulatory actions could materially adversely affect our financial results or harm our reputation or brands.Claims for losses or injuries purportedly caused by some of our products arise in the ordinary course of our business. In addition to the risk of litigationor regulatory enforcement actions and the associated costs and potential for monetary judgments and penalties, which could have an adverse effect on ourresults of operations and financial condition, product liability claims or regulatory actions, regardless of merit, could result in negative publicity that couldharm our reputation in the marketplace or the value of our consumer brands. We also could be required to recall and possibly discontinue the sale of defectiveor unsafe products, which could result in adverse publicity, significant expenses and adverse impacts to our financial position.Our success depends on our ability to attract and retain qualified personnel.Our success depends on our ability to attract and retain qualified personnel, including executive officers and other key personnel for a diverse, globalworkforce. We rely to a significant degree on compensating our executive officers and key employees with performance-based incentive awards that pay outonly if specified performance goals have been met. To the extent these performance goals are not met and our incentive awards do not pay out, or pay out lessthan the targeted amount, it may motivate certain executive officers and key employees to seek other opportunities and affect our ability to attract and retainqualified personnel. The loss of key management personnel or other key employees or our potential inability to attract such personnel may adversely affectour ability to manage our overall operations and successfully implement our business strategy.16Our stock price is volatile.The market price for our common stock has been volatile historically. Our stock price may be significantly affected by factors including those describedelsewhere in this "Part I, Item 1A. Risk Factors" as well as the following:•quarterly fluctuations in our operating results compared to market expectations;•investors' perceptions of the office products industry;•amounts we repurchase on the open market under our share repurchase program;•changes in financial estimates by us or securities analysts and recommendations by securities analysts; and•the composition of our stockholders, particularly the presence of "short sellers" trading in our stock.Volatility in our stock price could adversely affect our business and financing opportunities and force us to increase our cash compensation to ouremployees or grant larger stock awards, which could hurt our operating results and reduce the percentage ownership of our existing stockholders.Material disruptions resulting from telecommunication failures, labor strikes, power and/or water shortages, acts of God, war, terrorism, othergeopolitical incidents or other circumstances outside our control could adversely impact our business, results of operations and financial condition.A disruption at one of our facilities or at a third-party service provider’s facilities (especially facilities in China, other Asia-Pacific countries and LatinAmerica) could adversely impact production, and our customer deliveries which can negatively impact our operations and result in increased costs. Such adisruption could occur as a result of any number of events, including but not limited to, a major equipment failure, labor stoppages, transportation failuresaffecting the supply and shipment of materials and finished goods, the unavailability of raw materials, severe weather conditions, natural disasters, civilunrest, fire, explosions, health pandemics, war or terrorism and disruptions in utility and other services. Any such disruptions could adversely impact ourbusiness, results of operations and financial condition.ITEM 1B. UNRESOLVED STAFF COMMENTSNone.17ITEM 2.

LEGAL PROCEEDINGSWe are party to various lawsuits and regulatory proceedings, primarily related to alleged patent infringement and employee terminations as well asother claims incidental to our business. In addition, we may be unaware of third party claims of intellectual property infringement relating to our technology,brands or products and we may face other claims related to business operations. Any litigation regarding patents or other intellectual property could be costlyand time-consuming and might require us to pay monetary damages or enter into costly license agreements. We also may be subject to injunctions againstdevelopment and sale of certain of our products.It is the opinion of management that (other than the Brazilian Tax Assessment described below) the ultimate resolution of currently outstanding matterswill not have a material adverse effect on our financial condition, results of operations or cash flow. However, there is no assurance that we will ultimately besuccessful in our defense of any of these matters or that an adverse outcome in any matter will not negatively affect our results of operations, financialcondition or cash flow. Further, future claims, lawsuits and legal proceedings could materially and adversely affect our business, reputation, results ofoperations and financial condition.In connection with our May 1, 2012 acquisition of the Mead Consumer and Office Products business ("Mead C&OP"), we assumed all of the taxliabilities for the acquired foreign operations including Tilibra Produtos de Papelaria Ltda. ("Tilibra"). In December of 2012, the Federal Revenue Departmentof the Ministry of Finance of Brazil ("FRD") issued a tax assessment (the "Brazilian Tax Assessment") against Tilibra, which challenged the tax deduction ofgoodwill from Tilibra's taxable income for the year 2007 (the "First Assessment"). A second assessment challenging the deduction of goodwill from Tilibra'staxable income for the years 2008, 2009 and 2010 was issued by FRD in October 2013 (the "Second Assessment"). Tilibra is disputing both of the taxassessments.Recently, the final administrative appeal of the Second Assessment was decided against the Company. We intend to challenge this decision in court inearly 2018. In connection with the judicial challenge, we may be required to post security to guarantee payment of the Second Assessment, which represents$24.6 million of the current reserve, should we not prevail. The First Assessment is still being challenged through established administrative procedures.We believe we have meritorious defenses and intend to vigorously contest these matters; however, there can be no assurances that we will ultimatelyprevail. The ultimate outcome will not be determined until the Brazilian tax appeal process is complete, which is expected to take a number of years. Inaddition, Tilibra's 2012 tax year remains open and subject to audit, and there can be no assurances that we will not receive an additional tax assessmentregarding the goodwill for 2012. The time limit for issuing an assessment for 2011 expired in January 2018 and we did not receive an assessment. The timelimit for issuing an assessment for 2012 will expire in January 2019. If the FRD's initial position is ultimately sustained, the amount assessed wouldmaterially and adversely affect our cash flow in the year of settlement.Because there is no settled legal precedent on which to base a definitive opinion as to whether we will ultimately prevail, we consider the outcome ofthis dispute to be uncertain. Since it is not more likely than not that we will prevail, in 2012, we recorded a reserve in the amount of $44.5 million (atDecember 31, 2012 exchange rates) in consideration of this contingency, of which $43.3 million was recorded as an adjustment to the purchase price andwhich included the 2007-2012 tax years plus penalties and interest through December 2012. Included in this reserve is an assumption of penalties at 75%,which is the standard penalty. While there is a possibility that a penalty of 150% could be imposed in connection with the First Assessment, based on thefacts in our case and existing precedent, we believe the likelihood of a 150% penalty is not more likely than not as of December 31, 2017. We will continueto actively monitor administrative and judicial court decisions and evaluate their impact, if any, on our legal assessment of the ultimate outcome of our case.In addition, we will continue to accrue interest related to this contingency until such time as the outcome is known or until evidence is presented that we aremore likely than not to prevail. During the years ended December 31, 2017, 2016 and 2015, we accrued additional interest as a charge to current tax expenseof $2.2 million, $2.8 million and $2.7 million, respectively. At current exchange rates, our accrual through December 31, 2017, including tax, penalties andinterest is $38.7 million.ITEM 4. MINE SAFETY DISCLOSURESNot applicable.19PART IIITEM 5.

See below for an explanation of how we calculate and use these non-GAAP financial measuresand for a reconciliation of these non-GAAP financial measures to the most comparable GAAP financial measures.We use the non-GAAP financial measures both in the internal evaluation and management of our business and to explain our results to shareholders andthe investment community. Senior management’s incentive compensation is derived, in part, using certain of these measures. We believe these measuresprovide management and investors with a more complete understanding of our underlying operational results and trends, facilitate meaningful comparisonsand enhance an overall understanding of our past financial performance and our future prospects. The non-GAAP results are an indication of our baselineperformance before gains, losses or other charges that we considered to be outside our core operating results.The non-GAAP financial measures exclude certain items that may have a material impact upon our reported financial results such as unusual income taxitems, restructuring and integration charges, acquisition-related expenses, foreign currency fluctuation, and other one-time or non-recurring items. Thesemeasures should not be considered in isolation or as a substitute for, or superior to, the directly comparable GAAP financial measures and should be read inconnection with the company’s financial statements presented in accordance with GAAP.Net Sales at Constant CurrencyWe provide net sales at constant currency in order to facilitate comparisons of our historical sales results as well as highlight the underlying sales trendsin our business. We calculate net sales at constant currency by translating the current period foreign operation net sales at prior year currency rates.The following table provides a reconciliation of GAAP net sales as reported to non-GAAP net sales at constant currency: Year Ended December 31, 2017 Year Ended December31, 2016 (in millions of dollars)GAAP ReportedNet Sales CurrencyTranslation Non-GAAP Net Salesat Constant Currency GAAP Reported NetSales % Change at ConstantCurrencyACCO Brands North America$999.0 $(2.0) $997.0 $1,016.1 (1.9)%ACCO Brands EMEA542.8 (0.8) 542.0 171.8 215.5 %ACCO Brands International407.0 (9.6) 397.4 369.2 7.6 %Total$1,948.8 $(12.4) $1,936.4 $1,557.1 24.4 %23Adjusted Operating IncomeWe provide adjusted operating income in order to facilitate comparisons of our historical operating results by excluding one-time gains, losses andother charges, such as restructuring (credits) charges, integration charges and acquisition-related expenses.The following table provides a reconciliation of GAAP operating income as reported to non-GAAP adjusted operating income: Year Ended December 31, 2017(in millions of dollars)GAAP ReportedOperating Income Adjustments(1) Non-GAAP AdjustedOperating IncomeACCO Brands North America$155.6 $5.8 $161.4ACCO Brands EMEA37.1 17.5 54.6ACCO Brands International50.9 6.2 57.1Corporate(50.6) 8.0 (42.6)Total$193.0 $37.5 $230.5(1) Represents the adjustment of restructuring charges, transaction and integration expenses associated with the Esselte and PA Acquisitions, the gainon the sale of a distribution center related to the Pelikan Artline integration and the amortization of step-up in the value of finished goods inventoryassociated with the acquisition of Esselte.Free Cash FlowWe provide free cash flow in order to show the cash available to pay down debt, buy back shares of common stock, pay dividends and fund strategicacquisitions.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OFOPERATIONSINTRODUCTIONManagement’s Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with the consolidatedfinancial statements of ACCO Brands Corporation and the accompanying notes contained in Item 8. of this report. Unless otherwise noted, the followingdiscussion pertains only to our continuing operations.Overview of the CompanyACCO Brands is a designer, marketer and manufacturer of recognized consumer and end-user demanded brands used in businesses, schools, and homes.Our widely known brands include AT-A-GLANCE®, Derwent®, Esselte®, Five Star®, GBC®, Hilroy®, Kensington®, Leitz®, Marbig®, Mead®, NOBO®,Quartet®, Rapid®, Rexel®, Swingline®, Tilibra® and Wilson Jones®. More than 80% of our net sales come from brands that occupy the number one or numbertwo positions in the select product categories in which we compete. We distribute our products through a wide variety of retail and commercial channels toensure that our products are readily and conveniently available for purchase by consumers and other end-users, wherever they prefer to shop. These channelsinclude mass retailers, e-tailers, discount, drug/grocery and variety chains; warehouse clubs; hardware and specialty stores; independent office productdealers; office superstores; and contract stationers. Our products are sold primarily in the U.S., Europe, Australia, Canada, Brazil and Mexico. For the yearended December 31, 2017, approximately 55% of our sales were outside the U.S., up from 43% in 2016. This increase was the result of the Esselte and PelikanArtline acquisitions, which further extended our geographic reach.Over the past several years we have transformed our business by: divesting certain non-core commercially-oriented product lines; acquiring companieswith consumer and end-user demanded brands, and continuing to diversify our distribution channels. In 2012, we acquired the Mead Consumer and OfficeProducts business ("Mead C&OP"), which substantially increased our presence in North America and Brazil in school and calendar products with well-knownconsumer brands. In 2016, we purchased the remaining equity interest in Pelikan Artline from our joint venture partner, which enhanced our competitiveposition in school and business products in Australia and New Zealand and added new consumer categories, including writing instruments and janitorialsupplies. In early 2017, we acquired Esselte Group Holdings AB ("Esselte"), which more than doubled our presence in Europe and added several iconicbusiness brands, a significant base of independent dealer customers, and a new product category of do-it-yourself hardware tools. Together these threeacquisitions have meaningfully expanded our portfolio of well-known end-user demanded brands, enhanced our competitive position from both a productand channel perspective, and added scale to our business operations.Today our Company is a global enterprise focused on developing innovative branded consumer products for use in businesses, schools and homes. Webelieve our leading product category positions provide the scale to enable us to invest in marketing and product innovation to drive profitable growth. Weexpect to derive much of our growth, over the long term, in faster-growing emerging geographies such as Latin America and parts of Asia, the Middle Eastand Eastern Europe, which exhibit stronger demand for our product categories than in developed markets. In all of our markets we see opportunities to growsales through share gains, channel expansion and innovative products. We plan to supplement organic growth globally with strategic acquisitions in bothexisting and adjacent product categories.AcquisitionsEsselte Group Holdings AB Acquisition and RefinancingOn January 31, 2017, the Company completed the acquisition (the "Esselte Acquisition") of Esselte. Accordingly, the results of Esselte are included inthe Company's consolidated financial statements from February 1, 2017 forward and are reported in all three of the Company's segments, but primarily in theACCO Brands EMEA segment. The acquisition of Esselte made ACCO Brands a leading European manufacturer and marketer of branded consumer andoffice products, and improved ACCO Brands' scale. Esselte products are primarily marketed under the Leitz®, Rapid® and Esselte® brands in the storage andorganization, stapling, punching, binding and laminating equipment and do-it-yourself tools product categories.The cash purchase price paid was $292.3 million, net of cash acquired of $34.2 million. In connection with the Esselte Acquisition, the Companyentered into a Third Amended and Restated Credit Agreement (the "2017 Credit Agreement"), dated as of January 27, 2017. The 2017 Credit Agreementprovides for a five-year senior secured credit facility, which consists of a €300.0 million (US$320.8 million based on January 27, 2017 exchange rates) termloan facility (the "Euro Term Loan A"), a A$80.0 million (US$60.4 million based on January 27, 2017 exchange rates) term loan facility (the "AUD TermLoan A"), and a25US$400.0 million multi-currency revolving credit facility (the "2017 Revolving Facility").Pelikan Artline Joint-Venture AcquisitionOn May 2, 2016, we completed the acquisition of Australia Stationery Industries, Inc. (the "PA Acquisition"), which indirectly owned the 50% of thePelikan Artline joint-venture and the issued capital stock of Pelikan Artline Pty Limited (collectively, "Pelikan Artline") that was not already owned by theCompany. Prior to the PA Acquisition, the Pelikan Artline joint-venture was accounted for using the equity method. The results of Pelikan Artline areincluded in the Company's consolidated financial statements from May 2, 2016 forward, and are reported in the ACCO Brands International segment.Accordingly, we no longer separately report equity in earnings from this joint-venture. Pelikan Artline is a premier distributor of recognized consumer brandsused in businesses, schools, and homes in Australia and New Zealand.For further information on the acquisitions, see "Note 3. Acquisitions" to the consolidated financial statements contained in Item 8. of this report. Forinformation on the financings of the acquisitions, see "Note 4. Long-term Debt and Short-term Borrowings" to the consolidated financial statementscontained in Item 8. of this report.Reportable SegmentsEffective in the first quarter of 2017, as a result of the Esselte Acquisition, the Company realigned its operating structure, which affected the makeup ofits business segments for financial reporting purposes. The Company has three operating business segments each of which is comprised of differentgeographic regions. The Company no longer reports the results of its Computer Products Group as a separate segment. Results of the former ComputerProducts Group are reflected in the appropriate geographic segment based on the region from which sales are made. The Company's three realigned businesssegments are as follows:Operating Segment Geographic Regions Primary BrandsACCO Brands North America United States and Canada AT-A-GLANCE®, Five Star®, GBC®, Hilroy®, Kensington®,Mead®, Quartet®, and Swingline® ACCO Brands EMEA Europe, Middle East and Africa Derwent®, Esselte®, GBC®, Kensington®, Leitz®, NOBO®,Rapid®, and Rexel® ACCO Brands International Australia, Latin America and Asia-Pacific Artline®, GBC®, Kensington®, Marbig®, Quartet®, Rexel®,Tilibra®, and Wilson Jones®We have restated our financial statements for each of the periods presented to reflect this change in reportable business segments.Each of the Company's three operating segments designs, markets, sources, manufactures and sells recognized consumer and end-user demanded brandsused in businesses, schools and homes. Product designs are tailored based on end-user preferences in each geographic region.Our product categories include storage and organization; stapling; punching; laminating, binding and shredding machines and related consumablesupplies; whiteboards; notebooks; calendars; computer accessories; and do-it-yourself tools, among others. Our portfolio of consumer and end-userdemanded brands includes both globally and regionally recognized brands.ACCO Brands markets and sells its strong multi-product offering broadly and is not dependent on any one channel. Our products are sold through allrelevant channels, namely retailers, including: mass retailers; e-tailers; discount, drug/grocery and variety chains; warehouse clubs; hardware and specialtystores; independent office product dealers; office superstores; and contract stationers. We also sell directly to commercial and consumer end-users throughour e-commerce platform and our direct sales organization.For further information on our business segments see "Note 16. Information on Business Segments" to the consolidated financial statements containedin Part II, Item 8. of this report.Overview of 2017 PerformanceOur financial results for the year ended December 31, 2017 reflect the significant benefit of our acquisitions. The Esselte Acquisition and the PAAcquisition primarily impact the financial results of our EMEA and International segments, respectively. For more information, see "Note 3. Acquisitions" tothe consolidated financial statements contained in Item 8. of this report.26The Company's cash flow from operations, effective tax rate and interest payments were impacted by the refinancing of our senior unsecured notes inDecember 2016 to obtain a lower interest rate, and the increase in our bank debt in January 2017 to finance the Esselte Acquisition. For further information,see "Note 4. Long-term Debt and Short-term Borrowings" to the consolidated financial statements contained in Item 8. of this report.In addition, we recorded a tax benefit of $25.7 million related to the newly passed U.S Tax Act in December of 2017.

Foreign currency translation increased sales by $12.4 million, or 1% in the current-year period. Comparable net sales,excluding the acquisitions and foreign currency translation, were down primarily due to declines at certain office superstore customers and lost productplacements.Cost of Products SoldCost of products sold includes all manufacturing, product sourcing and distribution costs, including depreciation related to assets used in themanufacturing, procurement and distribution processes, allocation of certain information technology costs supporting those processes, inbound andoutbound freight, shipping and handling costs, purchasing costs associated with materials and packaging used in the production processes and inventoryvaluation adjustments. Cost of products sold of $1,292.4 million, was up $250.4 million, or 24%, from $1,042.0 million in the prior-year period. Foreigncurrency translation reduced cost of27products sold by $8.4 million, or 1% in the current-year period. Underlying cost of products sold, excluding foreign currency translation, increased due to theinclusion of the acquisitions, partially offset by lower comparable sales and cost savings and productivity improvements.Gross ProfitWe believe that gross profit and gross profit margin provide enhanced shareholder appreciation of underlying profit drivers. Gross profit of $656.4million, was up $141.3 million, or 27%, from $515.1 million in the prior-year period. Foreign currency translation increased gross profit by $4.0 million, or1% in the current-year period. Underlying gross profit, excluding foreign currency translation, increased due to the inclusion of the acquisitions, togetherwith productivity initiatives and higher pricing, which was partially offset by lower comparable sales and inflation.Gross profit as a percent of net sales increased to 33.7% from 33.1%. The increase was primarily due to productivity improvements and higher pricing.Selling, General and Administrative expensesSelling, general and administrative expenses ("SG&A") include advertising, marketing, selling (including commissions), research and development,customer service, depreciation related to assets outside the manufacturing and distribution processes, and all other general and administrative expensesoutside the manufacturing and distribution functions (e.g., finance, human resources, information technology and corporate expenses). SG&A of $406.1million, was up $85.3 million, or 27%, from $320.8 million in the prior-year period. The current-year period includes $16.4 million of integration andtransaction costs related to the acquisitions. The prior-year period included $12.8 million in transaction and integration costs related to the acquisitions.Foreign currency translation increased SG&A by $0.6 million, or 0.2%, in the current-year period. Underlying SG&A, excluding integration and transactioncosts and foreign currency translation, increased primarily due to the inclusion of the acquisitions.As a percentage of net sales, SG&A increased to 20.8% from 20.6% in the prior-year period, primarily due to higher integration and transaction costsincurred in the current-year period, partially offset by productivity initiatives.Amortization of IntangiblesAmortization of intangibles of $35.6 million, was up $14.0 million, or 65%, from $21.6 million in the prior-year period. The increase was due to theinclusion of the Esselte and PA Acquisitions.Restructuring ChargesRestructuring charges in the current-year period of $21.7 million related primarily to the integrations of Esselte and Pelikan Artline. Restructuringcharges in the prior-year period of $5.4 million related primarily to the integration of Pelikan Artline and consolidation of certain functions in the NorthAmerica segment.Operating IncomeOperating income of $193.0 million, was up $25.7 million, or 15%, from $167.3 million in the prior-year period. Foreign currency translation increasedoperating income by $3.2 million, or 2%, in the current-year period. Underlying operating income, excluding restructuring, transaction and integration costs,and foreign currency translation, increased primarily due to the inclusion of the acquisitions.Interest Expense, Equity in Earnings of Joint Venture and Other (Income) Expense, NetInterest expense of $41.1 million, was down $8.2 million, or 17%, from $49.3 million in the prior-year period. The decrease was primarily due to thelower interest rate paid on our senior unsecured notes, which were refinanced in the fourth quarter of 2016, partially offset by interest resulting from increaseddebt incurred in connection with the Esselte Acquisition. The prior-year period included $2.5 million of incremental interest expense related to the above-referenced refinancing of our senior unsecured notes and the accelerated amortization of debt issuance cost related to the prepayment of $70 million on ourU.S. Dollar Senior Secured Term Loan A.As a result of the PA Acquisition, which was completed on May 2, 2016, equity in earnings of joint venture decreased $2.1 million as the Companyceased accounting for the Pelikan Artline joint-venture using the equity method of accounting.28Other (income) expense, net was income of $0.4 million compared to expense of $1.4 million in the prior-year period. The current-year period includeda $2.3 million foreign currency gain related to the settlement of certain intercompany loan transactions. The prior-year period included charges associatedwith the refinancing of our senior unsecured notes. These charges consisted of $25.0 million in a "make-whole" call premium and a $4.9 million charge forthe write-off of debt issuance costs, which were offset by a $28.9 million non-cash gain arising from the PA Acquisition due to the revaluation of theCompany's previously held equity interest to fair value and a gain on the settlement of an intercompany loan of $1.0 million, previously deemedpermanently invested.Income TaxesFor the current-year period, income tax expense was $26.4 million on income before taxes of $158.1 million, or an effective tax rate of 16.7%. The loweffective tax rate for the current-year period is primarily due to a net tax benefit of $25.7 million related to the newly passed U.S. Tax Act in December of2017. This benefit was driven by the reduction of net deferred tax liabilities, partially offset by a one-time mandatory deemed repatriation tax onaccumulated foreign subsidiaries' previously untaxed foreign earnings (the "Transition Toll Tax"). For further information on the impact of the U.S. Tax Act,see "Note 11. Income Taxes" to the consolidated financial statements contained in Item 8. of this report. Also contributing to the low effective rate was $5.6million of excess tax benefits from stock-based compensation related to the adoption of ASU No. 2016-09, Compensation - Stock Compensation (Topic 718):Improvements to Employee Share-Based Payment Accounting. See "Note 2. Significant Accounting Policies" to the consolidated financial statementscontained in Item 8. of this report for details on the adoption of this new standard.For the prior-year period, income tax expense was $29.6 million on income before taxes of $125.1 million, or an effective tax rate of 23.7%. The loweffective tax rate in the prior-year period was primarily due to the following: 1) the $28.9 million gain arising from the PA Acquisition due to the revaluationof the previously held equity interest to fair value, which was not subject to tax, and 2) tax losses on foreign exchange on the repayment of intercompanyloans, for which the pre-tax effect was recorded in equity.Net IncomeNet income of $131.7 million, was up $36.2 million, or 38%, from $95.5 million in the prior-year period. Diluted income per share was $1.19, up $0.32,or 37% from $0.87 per diluted share in the prior-year period. Foreign currency translation increased net income by $5.9 million, or 6% in the current-yearperiod. The increase in net income was primarily due to inclusion of the acquisitions, lower interest expense and a lower effective tax rate.Segment Net Sales and Operating Income for the Years Ended December 31, 2017 and 2016 Year Ended December 31, 2017 Amount of Change Net Sales SegmentOperatingIncome(1) OperatingIncome Margin Net Sales Net Sales SegmentOperatingIncome SegmentOperatingIncome MarginPoints (in millions of dollars) $ % $ % ACCO Brands North America$999.0 $155.6 15.6% $(17.1) (2)% $2.3 2% 50ACCO Brands EMEA542.8 37.1 6.8% 371.0 216% 24.5 194% (50)ACCO Brands International407.0 50.9 12.5% 37.8 10% 1.5 3% (90)Total$1,948.8 $243.6 $391.7 $28.3 Year Ended December 31, 2016 Net Sales SegmentOperatingIncome(1) OperatingIncome Margin (in millions of dollars) ACCO Brands North America$1,016.1 $153.3 15.1% ACCO Brands EMEA171.8 12.6 7.3% ACCO Brands International369.2 49.4 13.4% Total$1,557.1 $215.3 (1)Segment operating income excludes corporate costs: "Interest expense;" "Interest income;" "Equity in earnings of joint-venture" and "Other (income)expense, net."

Foreign currency translation increased sales by $2.0 million, or 0.2%, in the current-year period.Comparable net sales, excluding Esselte and foreign currency translation, decreased primarily due to continued declines with office superstore customers andlost product placements with certain customers. Sales during the back-to-school season were down slightly compared to the prior year, which had stronggrowth.ACCO Brands North America operating income of $155.6 million, was up $2.3 million, or 2%, from $153.3 million in the prior-year period, andoperating income as a percent of net sales increased to 15.6% from 15.1%. The increase was due to higher gross margins from cost savings and productivityinitiatives, and reduced customer sales rebates, which were partially offset by lower comparable sales, higher go-to-market spending and $5.5 million inrestructuring charges (versus $1.1 million in the prior-year period). The restructuring charges related to the realignment of the operating structure of ourformer Computer Products Group, the Esselte integration and other projects to enhance the future long-term performance of the business.ACCO Brands EMEAACCO Brands EMEA net sales of $542.8 million, including approximately $388 million attributable to the Esselte Acquisition, were up $371.0million, or 216%, from $171.8 million in the prior-year period. Foreign currency translation increased sales by $0.8 million, or 0.5%, in the current-yearperiod. Comparable net sales, excluding Esselte and foreign currency translation, decreased due to lost product placements and inventory reductions bycertain customers.ACCO Brands EMEA operating income of $37.1 million, including approximately $24.9 million attributable to the Esselte Acquisition, was up $24.5million, or 194%, from $12.6 million in the prior-year period, but operating income as a percent of net sales decreased to 6.8% from 7.3%. The increase inoperating income was driven by the Esselte Acquisition and includes restructuring costs of $11.2 million, integration costs of $5.5 million, and theamortization of step-up in the value of finished goods inventory of $0.8 million. Foreign currency translation increased operating income by $2.4 million inthe current-year period. Underlying operating income, excluding Esselte, restructuring and integration costs, foreign currency translation and theamortization of step-up in the value of finished goods inventory, decreased due to lower comparable sales, partially offset by reduced SG&A expenses.Operating income as a percent of sales decreased due to restructuring and integration costs, higher intangible amortization resulting from the EsselteAcquisition and lower gross margins (primarily due to Esselte having lower margins than the legacy ACCO business), partially offset by the lower SG&Amargins in the legacy Esselte business.ACCO Brands InternationalACCO Brands International net sales of $407.0 million, including $37.9 million attributable to the PA and Esselte Acquisitions, were up $37.8 million,or 10%, from $369.2 million in the prior-year period. Foreign currency translation increased sales by $9.6 million, or 3% in the current-year period.Comparable net sales, excluding acquisitions and foreign currency translation, decreased primarily due to lost product placements and inventory reductionsin Australia, partially offset by higher sales in Brazil and Mexico.ACCO Brands International operating income of $50.9 million, was up $1.5 million, or 3%, from $49.4 million in the prior-year period, but operatingincome as a percent of net sales decreased to 12.5% from 13.4%. Restructuring and integration costs in the current-year period were $5.0 million and $2.6million, respectively. In addition, the current-year period includes a $1.5 million gain on the sale of a distribution center in New Zealand related to theintegration of Pelikan Artline. The prior-year period includes restructuring costs of $4.3 million, integration costs of $2.3 million and the amortization of thestep-up in value of the finished goods inventory of $0.4 million. Foreign currency translation increased operating income by $0.7 million in the current-yearperiod. Underlying operating income, excluding restructuring and integration costs, the amortization of step-up in the value of finished goods inventory, thegain on sale of the distribution center and foreign currency translation, was flat due to the inclusion of the results of Pelikan Artline in the current-year periodand improved profitability in Brazil and Mexico, which was offset by lower comparable net sales and higher distribution costs associated with the warehouseand IT system consolidation in Australia.30Consolidated Results of Operations for the Years Ended December 31, 2016 and 2015 Year Ended December 31, Amount of Change (in millions of dollars, except per share data)2016(1) 2015 $ %/pts Net sales$1,557.1 $1,510.4 $46.7 3 % Cost of products sold1,042.0 1,032.0 10.0 1 % Gross profit515.1 478.4 36.7 8 % Gross profit margin33.1% 31.7% 1.4ptsAdvertising, selling, general and administrative expenses320.8 295.7 25.1 8 % Amortization of intangibles21.6 19.6 2.0 10 % Restructuring charges (credits)5.4 (0.4) 5.8 NM Operating income167.3 163.5 3.8 2 % Operating income margin10.7% 10.8% (0.1)ptsInterest expense49.3 44.5 4.8 11 % Interest income(6.4) (6.6) (0.2) (3)% Equity in earnings of joint venture(2.1) (7.9) 5.8 (73)% Other expense, net1.4 2.1 (0.7) (33)% Income tax expense29.6 45.5 (15.9) (35)% Effective tax rate23.7% 34.6% (10.9)ptsNet income95.5 85.9 9.6 11 % Weighted average number of diluted shares outstanding:109.2 110.6 (1.4) (1)% Diluted income per share$0.87 $0.78 $0.09 12 % (1)The Company acquired Pelikan Artline on May 2, 2016; the results of which are included in 2016 results from that date forward.Net SalesNet sales of $1,557.1 million, including $78.5 million attributable to the PA Acquisition, were up $46.7 million, or 3%, from $1,510.4 million in theprior-year period. Foreign currency translation reduced net sales by $16.9 million, or 1%. Comparable net sales, excluding Pelikan Artline and foreigncurrency translation, were down due to declines at certain wholesalers and office superstores customers, partially offset by strong growth at mass and e-tailcustomers.Cost of Products SoldCost of products sold of $1,042.0 million, including $47.7 million attributable to the PA Acquisition, was up $10.0 million, or 1%, from $1,032.0million in the prior-year period. Foreign currency translation decreased cost of products sold by $13.3 million, or 1%. Underlying cost of products sold,excluding Pelikan Artline and foreign currency translation, decreased due to lower sales volume and productivity improvements, partially offset by foreign-exchange-related inflationary increases in certain foreign markets' cost of products sold.Gross ProfitGross profit of $515.1 million, including $30.8 million attributable to the PA Acquisition, was up $36.7 million, or 8%, from $478.4 million in theprior-year period. Foreign currency translation decreased gross profit by $3.6 million, or 1%. Underlying gross profit, excluding Pelikan Artline and foreigncurrency translation, increased due to higher pricing and productivity improvements, which were partially offset by foreign-exchange-related inflationaryincreases in certain foreign markets' costs of products sold.Gross profit as a percent of net sales increased to 33.1% from 31.7% in the prior-year period. The increase was primarily due to cost savings andproductivity improvements, higher pricing and the positive impact of the PA Acquisition.31Selling, General and Administrative ExpensesSG&A of $320.8 million, including $16.6 million attributable to the PA Acquisition, was up $25.1 million, or 8%, from $295.7 million in the prior-yearperiod. Foreign currency translation reduced SG&A by $4.8 million, or 2%. The prior-year period included $3.6 million of integration and transaction costsrelated to the PA Acquisition. Underlying SG&A, excluding Pelikan Artline and foreign currency translation, increased, driven by higher professional fees,including $9.2 million of transaction costs related to the Esselte Acquisition. Additionally, the prior-year period benefited from a one-time $2.3 millionrecovery of an indirect tax in Brazil.As a percentage of net sales, SG&A increased to 20.6% from 19.6% in the prior-year period for the reasons mentioned above.Restructuring Charges (Credits)We initiated cost reduction plans related to the consolidation and integration of Pelikan Artline with our already existing Australian and New Zealandbusinesses and, as a result, incurred $4.2 million of charges in 2016, primarily related to severance. In addition, in 2016 we initiated additional cost reductionplans and incurred $1.2 million of severance charges related to the consolidation of certain functions in the North America segment.Amortization of IntangiblesAmortization of intangibles was $21.6 million, up $2.0 million, or 10%, from $19.6 million in the prior-year period. The increase was due to theinclusion due to the PA Acquisition.Operating IncomeOperating income of $167.3 million, including $5.6 million attributable to the PA Acquisition, was up $3.8 million, or 2%, from $163.5 million in theprior-year period. Foreign currency translation increased operating income by $1.6 million, or 1%. Underlying operating income, excluding the PAAcquisition and foreign currency translation, decreased primarily due to increased SG&A.Interest Expense and Other Expense, NetInterest expense of $49.3 million, was up $4.8 million, or 11%, from $44.5 million in the prior-year period. The increase was primarily due to additionaldebt incurred to finance the PA Acquisition and the refinancing of our senior unsecured notes which resulted in the payment of $2.5 million of incrementalinterest expense. Also contributing to the increase was the accelerated amortization of debt issuance cost related to the prepayment of $70 million on our U.S.Dollar Senior Secured Term Loan A.Other expense, net of $1.4 million was down $0.7 million from $2.1 million in the prior-year period. The 2016 year included charges associated withthe above referenced refinancing of our senior unsecured notes. These charges consisted of $25.0 million in a "make-whole" call premium and a $4.9 millioncharge for the write-off of debt issuance costs, which were offset by a $28.9 million non-cash gain arising from the PA Acquisition due to the revaluation ofthe Company's previously held equity interest to fair value and a gain on the settlement of an intercompany loan of $1.0 million, previously deemedpermanently invested. In the prior-year period we wrote-off $1.9 million of debt issuance costs related to the refinancing completed in 2015.Income TaxesIncome tax expense was $29.6 million on income before taxes of $125.1 million, or an effective tax rate of 23.7%. For the prior-year period, income taxexpense was $45.5 million on income before taxes of $131.4 million, or an effective tax rate of 34.6%. The low effective tax rate in 2016 was primarily due tothe following: 1) the $28.9 million non-cash gain arising from the PA Acquisition due to the revaluation of the previously held equity interest to fair value,which was not subject to tax, and 2) tax losses on foreign exchange on the repayment of intercompany loans, for which the pre-tax effect was recorded inequity.Net IncomeNet income was $95.5 million, up $9.6 million, or 11%, from $85.9 million in the prior-year period.

Foreigncurrency translation reduced sales by $4.1 million, or 0.4%. Comparable net sales, excluding foreign currency translation, decreased due to declines at certainwholesalers and an office products superstore due to inventory reductions and consumers purchasing in different channels. The net sales decline was partiallyoffset by strong back-to-school sales, notably with mass-market customers and e-tailers, due to increased product placements and broadened productofferings.ACCO Brands North America operating income of $153.3 million, was up $1.7 million, or 1%, from $151.6 million in the prior-year period.

Foreign currency translation reduced sales by $4.2 million,33or 1%. Comparable net sales, excluding Pelikan Artline and foreign currency translation, increased due to higher pricing, which benefited sales by 9%. Priceincreases were implemented to recover gross margins following foreign-exchange-related cost of products sold increases, in Australia and Mexico, as well asto offset paper related inflation in Brazil. Partially offsetting the price increases were volume declines, primarily in the legacy ACCO Brands Australianbusiness.ACCO Brands International operating income of $49.4 million, including $6.9 million attributable to the PA Acquisition, increased $20.3 million, or70%, from $29.1 million in the prior-year period, and operating income as a percent of net sales increased to 13.4% from 10.2% in the prior-year period.Pelikan Artline operating income of $6.9 million includes restructuring costs of $4.2 million and integration costs of $2.3 million. Foreign currencytranslation increased operating income by $1.7 million, or 6%, due to the recovery of the Brazilian real, which occurred in the seasonally stronger fourthquarter. Underlying operating income, excluding Pelikan Artline and foreign currency translation, increased due to higher pricing and productivityimprovements, partially offset by lower volumes. In addition, the prior-year period included a one-time $2.3 million recovery of an indirect tax and $1.3million of severance charges, both in Brazil.Liquidity and Capital ResourcesOur primary liquidity needs are to service indebtedness, fund capital expenditures and support working capital requirements. Our principal sources ofliquidity are cash flows from operating activities, cash and cash equivalents held and seasonal borrowings under our 2017 Revolving Facility. As ofDecember 31, 2017, there was $133.9 million in borrowings outstanding under our $400.0 million 2017 Revolving Facility and the amount available forborrowings was $255.0 million (allowing for $11.1 million of letters of credit outstanding on that date).We maintain adequate financing arrangements at market rates. Because of the seasonality of our business, we typically generate much of our cash flowin the first, third and fourth quarters, as accounts receivables are collected, and we use cash in the second quarter to fund working capital in order to supportthe North America back-to-school season. Our Brazilian business is highly seasonal due to the timing of the back-to-school season, which coincides with thecalendar year-end in the fourth quarter. Due to various tax laws, it is costly to transfer short-term working capital in and out of Brazil; therefore, our normalpractice is to hold seasonal cash requirements in Brazil, and invest in short-term Brazilian government securities. Consolidated cash and cash equivalents was$76.9 million as of December 31, 2017, approximately $31 million of which was held in Brazil.On February 12, 2018, the Company's Board of Directors approved the initiation of a cash dividend program under which the Company will pay aregular quarterly cash dividend of $0.06 per share on its common stock ($0.24 per share on an annualized basis). In addition, on February 14, 2018, theCompany announced that its Board of Directors had approved an authorization to repurchase up to an additional $100 million in shares of its common stock.As of December 31, 2017, the Company had $84.0 million remaining of its prior authorizations.Our priorities for cash flow use over the near term, after funding business operations, including restructuring expenditures, are debt reduction,dividends, stock repurchases and to fund strategic acquisitions.The current senior secured credit facilities had a weighted average interest rate of 3.48% as of December 31, 2017 and our senior unsecured notes have afixed interest rate of 5.25%.Debt Amendments and RefinancingThird Amended and Restated Credit AgreementIn connection with the Esselte Acquisition, the Company entered into a Third Amended and Restated Credit Agreement (the "2017 Credit Agreement"),dated as of January 27, 2017, among the Company, certain subsidiaries of the Company, Bank of America, N.A., as administrative agent, and the other agentsand various lenders party thereto. The 2017 Credit Agreement amended and restated the Company’s Second Amended and Restated Credit Agreement datedApril 28, 2015 (the "2015 Credit Agreement").The 2017 Credit Agreement provides a five-year senior secured credit facility, which consists of a €300 million (US$320.8 million based on January 27,2017 exchange rates) term loan facility (the "Euro Term Loan A"), a A$80 million (US$60.4 million based on January 27, 2017 exchange rates) term loanfacility (the "AUD Term Loan A" and, together with the Euro Term Loan A, the "2017 Term A Loan Facility"), and a US$400 million multi-currencyrevolving credit facility (the "2017 Revolving Facility").34Maturity and AmortizationBorrowings under the 2017 Revolving Facility and the 2017 Term A Loan Facility mature on January 27, 2022. Amounts under the 2017 RevolvingFacility are non-amortizing. Beginning June 30, 2017, the outstanding principal amounts under the 2017 Term A Loan Facility are payable in quarterlyinstallments in an amount representing, on an annual basis, 5.0% of the initial aggregate principal amount of such loan facility and increasing to 12.5% on anannual basis by June 30, 2020.Interest ratesAmounts outstanding under the 2017 Credit Agreement bear interest at a rate per annum equal to the Euro Rate with a 0% floor, the Australian BBSRRate, the Canadian BA Rate or the Base Rate, as applicable and as each such rate is defined in the 2017 Credit Agreement, plus an "applicable rate." Theapplicable rate applied to outstanding Euro, Australian and Canadian dollar denominated loans and Base Rate loans is based on the Company’sConsolidated Leverage Ratio (as defined in the 2017 Credit Agreement) as follows:ConsolidatedLeverage Ratio Applicable Rate onEuro/AUD/CDN DollarLoans Applicable Rate on BaseRate Loans> 4.00 to 1.00 2.50% 1.50%≤ 4.00 to 1.00 and > 3.50 to 1.00 2.25% 1.25%≤ 3.50 to 1.00 and > 3.00 to 1.00 2.00% 1.00%≤ 3.00 to 1.00 and > 2.00 to 1.00 1.50% 0.50%≤ 2.00 to 1.00 1.25% 0.25%As of December 31, 2017, the applicable rate on Euro, Australian and Canadian dollar loans was 1.50% and the applicable rate on Base Rate loans was0.50%. Undrawn amounts under the 2017 Revolving Facility are subject to a commitment fee of 0.25% to 0.40% per annum, depending on the Company’sConsolidated Leverage Ratio. As of December 31, 2017, the commitment fee rate was 0.30%.PrepaymentsSubject to certain conditions and specific exceptions, the 2017 Credit Agreement requires the Company to prepay outstanding amounts under the 2017Credit Agreement under various circumstances, including (a) if sales or dispositions of certain property or assets in any fiscal year results in the receipt of netcash proceeds of $12.0 million, then an amount equal to 100% of the net cash proceeds received in excess of such $12.0 million, and (b) with respect to theAUD Term Loan A, in an amount equal to 100% of the net cash proceeds received from the disposition of any real property located in Australia. TheCompany also would be required to make prepayments in the event it receives proceeds related to certain property insurance or condemnation awards, fromadditional debt other than debt permitted under the 2017 Credit Agreement and from excess cash flow as determined under the 2017 Credit Agreement. The2017 Credit Agreement also contains other customary prepayment obligations and provides for voluntary commitment reductions and prepayment of loans,subject to certain conditions and exceptions.Dividends and Share RepurchasesUnder the 2017 Credit Agreement, the Company may pay dividends and/or repurchase shares in an aggregate amount not to exceed the sum of: (i) thegreater of $30 million and 1.00% of the Company’s Consolidated Total Assets (as defined in the 2017 Credit Agreement); plus (ii) an additional amount notto exceed $75.0 million in any fiscal year (provided the Company’s Consolidated Leverage Ratio after giving pro forma effect to the restricted paymentwould be greater than 2.50:1.00 and less than or equal to 3.75:1.00); plus (iii) an additional amount so long as the Consolidated Leverage Ratio after givingpro forma effect to the restricted payment would be less than or equal to 2.50:1.00; plus (iv) any Net Equity Proceeds (as defined in the 2017 CreditAgreement).Financial CovenantsThe Company’s Consolidated Leverage Ratio as of the end of any fiscal quarter may not exceed 3.75:1.00; provided that following the consummationof a Material Acquisition (as defined in the 2017 Credit Agreement), and as of the end of the fiscal quarter in which such Material Acquisition occurred andas of the end of the three fiscal quarters thereafter, the maximum35Consolidated Leverage Ratio level above will increase by 0.50:1.00, provided that no more than one such increase can be in effect at any time. The EsselteAcquisition qualified as a Material Acquisition under the 2017 Credit Agreement.The 2017 Credit Agreement requires the Company to maintain a Consolidated Fixed Charge Coverage Ratio (as defined in the 2017 Credit Agreement)as of the end of any fiscal quarter at or above 1.25 to 1.00.As of December 31, 2017, our Consolidated Leverage Ratio was approximately 2.6 to 1 and our Fixed Charge Coverage Ratio was approximately 5.3 to1.Other Covenants and RestrictionsThe 2017 Credit Agreement contains customary affirmative and negative covenants as well as events of default, including payment defaults, breachof representations and warranties, covenant defaults, cross-defaults, certain bankruptcy or insolvency events, certain ERISA-related events, changes in controlor ownership and invalidity of any loan document. The 2017 Credit Agreement also establishes limitations on the aggregate amount of PermittedAcquisitions and Investments (each as defined in the 2017 Credit Agreement) that the Company and its subsidiaries may make during the term of the 2017Credit Agreement.As of and for the periods ended December 31, 2017 and December 31, 2016, the Company was in compliance with all applicable loan covenants.Guarantees and SecurityGenerally, obligations under the 2017 Credit Agreement are guaranteed by certain of the Company’s existing and future subsidiaries, and are securedby substantially all of the Company’s and certain guarantor subsidiaries’ assets, subject to certain exclusions and limitations.Incremental FacilitiesThe 2017 Credit Agreement permits the Company to seek increases in the size of the 2017 Revolving Facility and the 2017 Term A Loan Facility priorto maturity by up to $500.0 million in the aggregate, subject to lender commitment and the conditions set forth in the 2017 Credit Agreement.Senior Unsecured Notes due December 2024On December 22, 2016, the Company completed a private offering of $400.0 million in senior unsecured notes, due December 2024 (the "New Notes"),which bear interest at 5.25%. Net proceeds from the sale of the New Notes, together with borrowings of $73.9 million under the Company's revolving creditfacility and cash on hand, were used to redeem the then existing senior unsecured notes (the "Old Notes"). The aggregate redemption price of $531.5 millionconsisted of principal due and payable on the Old Notes, a "make-whole" call premium of $25.0 million (included in "Other (income) expense, net"), andaccrued and unpaid interest of $6.5 million (included in "Interest expense") which the Company irrevocably deposited with the trustee of the Old Notesthereby satisfying all its obligations related to the Old Notes.Also included in "Other expense, net" is a $4.9 million charge for the write-off of debt issuance costs associated with the Old Notes. Additionally, weincurred and capitalized approximately $6.1 million in bank, legal and other fees associated with the issuance of the New Notes.Restructuring and Integration ActivitiesFrom time to time the Company may implement restructuring, realignment or cost-reduction plans and activities, including those related to integratingacquired businesses.During the year ended December 31, 2017, the Company recorded an aggregate $21.7 million in restructuring expenses primarily related to theintegration of the ACCO Brands and Esselte operations worldwide. The remaining charges relate to the integration of ACCO Brands and Pelikan Artlineoperations in Australia and New Zealand, and the change in the operating structure in North America, including integration of our former Computer ProductsGroup into our remaining business segments. As of December 31, 2017, there was $13.3 million remaining of restructuring liability on our ConsolidatedBalance Sheet. For further information, see "Note 10. Restructuring" to the consolidated financial statements contained in Item 8. of this report.36In addition, during the year ended December 31, 2017, the Company recorded an aggregate $11.4 million in non-restructuring integration expensesrelated to the integration of the ACCO Brands and Esselte and Pelikan Artline operations.During the first quarter of 2018, the Company approved additional restructuring projects aggregating to $3.5 million, primarily related to changes tothe structure in the ACCO Brands North America segment and the continued integration of Esselte in the ACCO Brands EMEA segment. In accordance withGAAP, none of the aforementioned liabilities were recorded in the fourth quarter of 2017.Consistent with our previous communications about the Esselte Acquisition, the Company currently expects it will record approximately $4 millionfor integration activities and $4 million of incremental restructuring expenses during the remainder of 2018, which is in addition to the $3.5 million ofrestructuring projects approved during the first quarter of 2018. As integration plans are still being finalized, it is not possible to reasonably estimate thenature or timing of these restructuring and integration charges or the timing of their associated cash outflows.Cash Flow for the Years Ended December 31, 2017 and 2016Cash Flow from Operating ActivitiesCash provided by operating activities during the year ended December 31, 2017 of $204.9 million was generated principally from increased operatingprofits, primarily due to the Esselte and PA Acquisitions. Cash generated by incremental operating profits was partially offset by lower contribution fromworking capital (accounts receivable, inventories, accounts payable), payments of professional fees associated with acquisition and integration activities forthe Esselte and PA Acquisitions, increased cash taxes and higher pension contributions. For the 2016 year, cash provided by operating activities was $167.1million. Net income for 2017 was $131.7 million compared to $95.5 million in 2016.The table below shows our cash flow from accounts receivable, inventories and accounts payable for the years ended December 31, 2017 and 2016,respectively:(in millions of dollars) 2017 2016Accounts receivable $10.2 $13.4Inventories 2.5 16.7Accounts payable (18.7) (19.3)Cash flow (used) provided by net working capital $(6.0) $10.8Accounts receivable contributed $10.2 million, which was lower than the prior year of $13.4 million due to the timing of the Esselte Acquisition andhigher sales in certain foreign markets. Inventory contributed $2.5 million, which was lower than the prior year of $16.7 million due to the Esselte and PAAcquisitions, inventory reductions at certain customers and inventory builds in support of warehouse integration activities. Partially offsetting the cashgenerated from net working capital were employee annual incentive payments made in the first quarter (including payroll taxes) related to transactionbonuses paid by the seller in connection with the Esselte Acquisition. The settlement of customer program liabilities was lower, primarily driven by lowersales in comparable businesses, partially offset by increased settlements from the Esselte Acquisition. Other significant cash fluctuations included income taxpayments of $34.8 million in 2017, which were higher than the $16.9 million paid in 2016 due to higher international taxes, largely related to the EsselteAcquisition, and pension contributions of $21.7 million in 2017, which increased from $6.2 million in 2016 due to higher U.S. contribution requirementsand the Esselte Acquisition. Restructuring payments of $13.4 million (primarily associated with headcount reductions and footprint rationalization activitiesin connection with the integration of Esselte and Pelikan Artline) were higher than the prior-year spend of $4.9 million. Interest payments were $38.0 million,lower than the prior-year payments of $50.1 million due to refinancing activities in late 2016 and lower debt.Cash Flow from Investing ActivitiesCash used by investing activities was $319.1 million and $106.4 million for the years ended December 31, 2017 and 2016, respectively. The 2017 cashoutflow reflects the $292.3 million purchase price, net of cash acquired, paid for Esselte. The 2016 cash outflow reflects the $88.8 million purchase price, netof cash acquired, paid for Pelikan Artline. For further information, see "Note 3. Acquisitions" to the consolidated financial statements contained in Item 8. ofthis report. Capital expenditures were $31.0 million and $18.5 million for the years ended December 31, 2017 and 2016, respectively, with the increasedriven by information technology systems-related investments.37Cash Flow from Financing ActivitiesCash provided by financing activities was $142.2 million for the year ended December 31, 2017, compared to $76.4 million used for the same period of2016. Cash provided in 2017 reflects long-term borrowings of $484.1 million, consisting of €300.0 million (US$320.8 million based on January 27, 2017exchange rates) in the form of the Euro Term Loan A incurred to fund the Esselte Acquisition, along with additional borrowings of US$91.4 million under theCompany's 2017 Revolving Facility, primarily to repay the then existing U.S. Dollar Senior Secured Term Loan A in the amount of $81.0 million and toreduce the outstanding balance on the Australian Dollar Senior Secured Term Loan A. Additionally, we used $41.8 million for repurchases of our commonstock and payments related to tax withholding for stock-based compensation, net of proceeds received from the exercise of stock options, and $3.6 million ofdebt issuance costs associated with the financing of the Esselte Acquisition.Cash used in 2016 of $76.4 million reflected long-term borrowings of $587.4 million, consisting primarily of a private issuance of New Notes of $400.0million and an incremental loan in the amount of A$100.0 million (US$76.6 million based on May 2, 2016 exchange rates), along with additionalborrowings under the Company’s then existing revolving facility, to fund the PA Acquisition. Repayments of long-term debt of $685.1 million primarilyreflects the early satisfaction and discharge of our $500 million principal amount of senior unsecured notes, repayments totaling $148.0 million on the thenexisting U.S. Dollar Senior Secured Term Loan A and payment of $24.5 million of debt assumed with the PA Acquisition. In 2016, we also made a "make-whole" call premium payment of $25.0 million related to the early satisfaction and discharge of our $500.0 million principal amount of senior unsecurednotes, and paid $6.9 million in debt issuance fees in connection with the New Notes.Cash Flow for the Years Ended December 31, 2016 and 2015Cash Flow from Operating ActivitiesFor the year ended December 31, 2016, cash provided by operating activities was $167.1 million compared to cash provided by the prior-yearoperating activities of $171.2 million. Net income for 2016 was $95.5 million compared to $85.9 million in 2015. The net operating cash inflow for the 2016year of $167.1 million was generated by enhanced profitability, improved net working capital management (accounts receivable, inventories, accountspayable) and incremental cash flow from the PA Acquisition. Cash outflows in 2016 included an accelerated interest payment of $6.5 million, in associationwith the early satisfaction and discharge of our senior unsecured notes. Additionally, $11.6 million of cash payments were for transaction and integrationcosts associated with the Esselte and PA Acquisitions.The table below shows our cash flow from accounts receivable, inventories and accounts payable for the years ended December 31, 2016 and 2015,respectively:(in millions of dollars) 2016 2015Accounts receivable $13.4 $(3.9)Inventories 16.7 9.8Accounts payable (19.3) (2.6)Cash flow provided by net working capital $10.8 $3.3Accounts receivable contributed $13.4 million in 2016 due to improved management of year-end collections. Inventory provided cash of $16.7 millionas a result of increased real-time inventory purchases earlier in the fourth quarter and improved forecasting, which also contributed to an increased use of cashfor accounts payable, which was $19.3 million in 2016, compared to $2.6 million in the prior year. Partially offsetting the cash generated from operatingprofit and net working capital were significant cash payments related to the settlement of customer program liabilities, which were higher than the prior yeardue to changes in 2016 customer mix and increased settlements in early 2016 (related to higher year-end 2015 purchases by certain customers to achieverebate levels). Outflows related to employee annual incentive payments made in the first quarter, underlying interest payments, income tax payments andrestructuring cash payments were similar to those made during the prior year.38Cash Flow from Investing ActivitiesCash used by investing activities was $106.4 million and $24.6 million for the year ended December 31, 2016 and 2015, respectively. The 2016 cashoutflow reflects the $88.8 million purchase price, net of cash acquired, paid for Pelikan Artline. For further information on the PA Acquisition, see "Note 3.Acquisition" to the consolidated financial statements contained in Item 8. of this report. Capital expenditures were $18.5 million and $27.6 million for theyears ended December 31, 2016 and 2015, respectively. The lower capital expenditures in 2016 reflects lower spending on information technology due to theimplementation of a new enterprise resource planning system in our European operations in the first quarter of 2016.Cash Flow from Financing ActivitiesCash used by financing activities was $76.4 million for the year ended December 31, 2016, compared to a use of $137.8 million for the same period of2015. Cash used in 2016 reflected long-term borrowings of $587.4 million, consisting primarily of a private issuance of the New Notes of $400.0 million andincremental Term A loan in the amount of A$100.0 million (US$76.6 million based on May 2, 2016 exchange rates), along with additional borrowings underthe Company’s existing revolving facility to fund the PA Acquisition. Repayments of long-term debt of $685.1 million primarily reflects the earlysatisfaction and discharge of our $500 million principal amount of senior unsecured notes, repayments totaling $148.0 million on the then existing U.S.Dollar Senior Secured Term Loan A and payment of $24.5 million of debt assumed with the PA Acquisition. In 2016, we also made a "make-whole" callpremium payment of $25.0 million related to the early satisfaction and discharge of our $500.0 million principal amount of senior unsecured notes, and paid$6.9 million in debt issuance fees in connection with the New Notes. Cash used in 2015 reflected net repayments of long-term debt of $70.1 million and$65.9 million to repurchase the Company's common stock and for payments related to tax withholding for share-based compensation.CapitalizationThe Company had 106.7 million shares of common stock outstanding as of December 31, 2017.Adequacy of Liquidity SourcesBased on our 2018 business plan and current forecasts, we believe that cash flow from operations, our current cash balance and other sources ofliquidity, including borrowings available under our 2017 Revolving Facility, will be adequate to support our requirements for working capital, capitalexpenditures, to pay dividends and to service indebtedness for the foreseeable future. Our future operating performance is dependent on many factors, someof which are beyond our control, including prevailing economic, financial and industry conditions. For further information on these risks, see "Part I, Item1A.Risk Factors - Our significant indebtedness requires us to dedicate a substantial portion of our cash flow to debt payments and limits our ability to engagein certain activities."Off-Balance-Sheet Arrangements and Contractual Financial ObligationsThe Company does not have any material off-balance-sheet arrangements that have, or are reasonably likely to have, a current or future effect on ourfinancial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.Our contractual obligations and related payments by period at December 31, 2017 were as follows:(in millions of dollars)2018 2019 - 2020 2021 - 2022 Thereafter TotalDebt$42.8 $89.4 $406.7 $400.0 $938.9Interest on debt(1)34.7 67.2 59.4 41.0 202.3Operating lease obligations28.1 46.6 28.4 17.6 120.7Purchase obligations(2)96.8 0.3 — — 97.1Other long-term liabilities(3)20.0 15.1 15.2 45.2 95.5Total$222.4 $218.6 $509.7 $503.8 $1,454.5(1)Interest calculated at December 31, 2017 rates for variable rate debt.(2)Purchase obligations primarily consist of contracts and non-cancelable purchase orders for raw materials and finished goods.(3)Other long-term liabilities consist of estimated expected employer contributions for 2018, along with estimated future payments, for pension and post-retirement plans that are not paid from assets held in a plan trust.39Due to the uncertainty with respect to the timing of future cash flows associated with our unrecognized tax benefits at December 31, 2017, we areunable to make reasonably reliable estimates of the period of cash settlement with the respective taxing authorities. Therefore, $47.2 million of unrecognizedtax benefits have been excluded from the contractual obligations table above. For further information, see "Note 11. Income Taxes" to the consolidatedfinancial statements contained in Item 8. of this report.Critical Accounting PoliciesOur financial statements are prepared in conformity with accounting principles generally accepted in the U.S. ("GAAP"). Preparation of our financialstatements requires us to make judgments, estimates and assumptions that affect the amounts of actual assets, liabilities, revenues and expenses presented foreach reporting period. Actual results could differ significantly from those estimates. We regularly review our assumptions and estimates, which are based onhistorical experience and, where appropriate, current business trends. We believe that the following discussion addresses our critical accounting policies,which require significant, subjective and complex judgments to be made by our management.Revenue RecognitionWe recognize revenue from product sales when earned, net of applicable provisions for discounts, returns and allowances. We consider revenue to berealized or realizable and earned when all of the following criteria are met: title and risk of loss have passed to the customer, persuasive evidence of anarrangement exists, delivery has occurred, the price is fixed or determinable and collectability is reasonably assured. We also provide our estimate ofpotential bad debt concurrent with recognizing revenue.Customer Program CostsCustomer programs and incentives are a common practice in our industry. We incur customer program costs to obtain favorable product placement, topromote sell-through of products and to maintain competitive pricing. Customer program costs and incentives, including rebates, promotional funds andvolume allowances, are accounted for as a reduction to gross sales. These costs are recorded at the time of sale based on management’s best estimates.Estimates are based on individual customer contracts and projected sales to the customer in comparison to any thresholds indicated by contract. In theabsence of a signed contract, estimates are based on historical or projected experience for each program type or customer. Management periodically reviewsaccruals for these rebates and allowances, and adjusts accruals when circumstances indicate (typically as a result of a change in sales volume expectations orcontractual obligations).Allowances for Doubtful Accounts and Sales ReturnsTrade receivables are recorded at the stated amount, less allowances for discounts, doubtful accounts and returns. The allowance for doubtful accountsrepresents estimated uncollectible receivables associated with potential customer defaults on contractual obligations, usually due to a customer's potentialinsolvency. The allowance includes amounts for certain customers where a risk of default has been specifically identified. In addition, the allowance includesa provision for customer defaults on a general formulaic basis when it is determined the risk of some default is probable and estimable, but cannot yet beassociated with a specific customer. The assessment of the likelihood of customer defaults is based on various factors, including the length of time thereceivables are past due, historical experience and existing economic conditions.The allowance for sales returns represents estimated uncollectible receivables associated with the potential return of products previously sold tocustomers, and is recorded at the same time that the sales are recognized. The allowance includes a general provision for product returns based on historicaltrends. In addition, the allowance includes a reserve for currently authorized customer returns that are considered to be abnormal in comparison to thehistorical basis.InventoriesInventories are priced at the lower of cost (principally first-in, first-out with minor amounts at average) or net realizable value. Inventory reserves arerecorded for obsolete or slow-moving inventory based on assumptions about future demand and marketability of products, the impact of new productintroductions and specific identification of items, such as product discontinuance or engineering/material changes. These estimates could vary significantly,either favorably or unfavorably, from actual requirements if future economic conditions, customer inventory levels or competitive conditions differ from ourexpectations.40Long-Lived AssetsWe test long-lived assets for impairment whenever events or changes in circumstances indicate that the assets’ carrying amount may not be recoverablefrom its undiscounted cash flow. When such events occur, we compare the sum of the undiscounted cash flow expected to result from the use and eventualdisposition of the asset or asset group to the carrying amount of a long-lived asset or asset group. The cash flows are based on our best estimate at the time offuture cash flow, derived from the most recent business projections. If this comparison indicates that there is an impairment, the amount of the impairment istypically calculated using discounted expected future cash flow. The discount rate applied to these cash flows is based on our weighted average cost ofcapital, computed by selecting market rates at the valuation dates for debt and equity that are reflective of the risks associated with an investment in ourindustry as estimated by using comparable publicly traded companies.Intangible AssetsIntangible assets are comprised primarily of indefinite-lived and amortizable intangible assets acquired and arising from the application of purchaseaccounting. Indefinite-lived intangible assets are not amortized, but are evaluated at least annually to determine whether the indefinite useful life isappropriate. In addition, amortizable intangible assets other than goodwill are amortized over their useful lives. Certain of our trade names have beenassigned an indefinite life as we currently anticipate that these trade names will contribute cash flows to ACCO Brands indefinitely.We test indefinite-lived intangibles for impairment at least annually, normally in the second quarter, and whenever market or business events indicatethere may be a potential adverse impact on a particular intangible. The review may be on a qualitative ("Step-Zero") or quantitative ("Step-1") basis asallowed by GAAP. We consider the implications of both external factors (e.g., market growth, pricing, competition, and technology) and internal factors (e.g.,product costs, margins, support expenses, and capital investment) and their potential impact on cash flows in both the near and long term, as well as theirimpact on any identifiable intangible asset associated with the business. Based on recent business results, consideration of significant external and internalfactors, and the resulting business projections, indefinite-lived intangible assets are reviewed to determine whether they are likely to remain indefinite-lived,or whether a finite life is more appropriate. In addition, based on events in the period and future expectations, management considers whether the potentialfor impairment exists. Finite lived intangibles are amortized over 10, 15, 23 or 30 years.We performed our annual assessment, on a qualitative basis, as allowed by GAAP, for the majority of our indefinite-lived trade names in the secondquarter of 2017 and concluded that no impairment existed. For two of our indefinite-lived trade names that are not substantially above their carrying values,Mead® and Hilroy®, we performed Step-1 tests in the second quarter of 2017. The following long-term growth rates and discount rates were used, 1.5% and10.5% for Mead®, and 1.5% and 11.0% for Hilroy®, respectively. We concluded that neither the Mead® nor Hilroy® trade names were impaired. The fair valueof the Mead® trade name was less than 30% above its carrying value as of the second quarter of 2017 Step-1 test. As of December 31, 2017, the carrying valueof the Mead® trade name was $113.3 million.As of June 1, 2017, we changed the indefinite-lived Hilroy® trade name to an amortizable intangible asset. The change was made as a result of decisionsregarding the Company's future use of the trade name. The Company commenced amortizing the Hilroy trade name June 1, 2017 on a straight-line basis overa life of 30 years.GoodwillGoodwill has been recorded on our balance sheet and represents the excess of the cost of an acquisition when compared to the fair value of the netassets acquired. The authoritative guidance on goodwill and other intangible assets requires that goodwill be tested for impairment at a reporting unit level.We have determined that our reporting units are ACCO Brands North America, ACCO Brands EMEA and ACCO Brands International.We test goodwill for impairment at least annually and whenever events or circumstances make it more likely than not that an impairment may haveoccurred. As permitted by GAAP, we may perform a qualitative assessment ("Step-Zero") to determine if it is more likely than not that the fair value of areporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform a quantitative goodwill impairment test ("Step-1")as required by GAAP. We performed our annual assessment in the second quarter of 2017, on a qualitative basis, and concluded that it was not more likelythan not that the fair value of any reporting unit is less than its carrying amount.If the qualitative assessment determines that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, or if it isdetermined that a qualitative assessment is not appropriate, we move onto the quantitative goodwill ("Step-1") impairment test where we calculate the fairvalue of the reporting units. When applying a fair-value-based test, the fair41value of a reporting unit is compared to its carrying value. If the fair value of a reporting unit exceeds the carrying value of the net assets assigned to areporting unit, goodwill is considered not impaired and no further testing is required. If the carrying value of the net assets assigned to a reporting unitexceeds the fair value of a reporting unit, an impairment charge is recognized, however, the loss recognized is not to exceed the total amount of goodwillallocated to the reporting unit.Given the current economic environment and the uncertainties regarding their impact on our business, there can be no assurance that our estimates andassumptions made for purposes of our qualitative impairment testing during 2017 will prove to be accurate predictions of the future. If our assumptionsregarding forecasted revenue or margin growth rates of certain reporting units are not achieved, we may be required to record impairment charges in futureperiods, whether in connection with our next annual impairment testing in the second quarter of fiscal year 2018 or prior to that, if a triggering event isidentified outside of the quarter when the annual impairment test is performed. It is not possible at this time to determine if any such future impairment chargewould result or, if it does, whether such charge would be material.Employee Benefit PlansWe provide a range of benefits to our employees and retired employees, including pension, post-retirement, post-employment and health care benefits.We record annual amounts relating to these plans based on calculations specified by GAAP, which include various actuarial assumptions, including discountrates, assumed rates of return, compensation increases, turnover rates and health care cost trend rates. Actuarial assumptions are reviewed on an annual basisand modifications to these assumptions are made based on current rates and trends when it is deemed appropriate. As required by GAAP, the effect of ourmodifications are generally recorded and amortized over future periods. We believe that the assumptions utilized in recording our obligations under the plansare reasonable based on our experience. The actuarial assumptions used to record our plan obligations could differ materially from actual results due tochanging economic and market conditions, higher or lower withdrawal rates or other factors which may impact the amount of retirement-related benefitexpense recorded by us in future periods.The discount rate assumptions used to determine the pension and post-retirement obligations of the benefit plans are based on a spot-rate yield curvethat matches projected future benefit payments with the appropriate interest rate applicable to the timing of the projected future benefit payments. Theassumed discount rates reflect market rates for high-quality corporate bonds currently available. Our discount rates were determined by considering theaverage of pension yield curves constructed of a large population of high quality corporate bonds. The resulting discount rates reflect the matching of planliability cash flows to the yield curves.The expected long-term rate of return on plan assets reflects management’s expectations of long-term average rates of return on funds invested based onour investment profile to provide for benefits included in the projected benefit obligations. The expected return is based on the outlook for inflation, fixedincome returns and equity returns, while also considering historical returns over the last 10 years, asset allocation and investment strategy.We estimate the service and interest components of net periodic benefit cost (income) for pension and post-retirement benefits utilizing a full yieldcurve approach by applying the specific spot rates along the yield curve used in the determination of the benefit obligation to the relevant projected cashflows.At the end of each calendar year an actuarial evaluation is performed to determine the funded status of our pension and post-retirement obligations andany actuarial gain or loss is recognized in accumulated other comprehensive income (loss) and then amortized into the income statement in future periods.Pension income was $4.9 million, $5.3 million and $5.1 million for the years ended December 31, 2017, 2016 and 2015, respectively. Post-retirementincome was $0.2 million, $0.7 million and $0.7 million for the years ended December 31, 2017, 2016 and 2015, respectively.The weighted average assumptions used to determine benefit obligations for the years ended December 31, 2017, 2016, and 2015 were as follows: Pension Post-retirement U.S. International 2017 2016 2015 2017 2016 2015 2017 2016 2015Discount rate3.7% 4.3% 4.6% 2.3% 2.7% 3.7% 3.2% 3.4% 3.9%Rate of compensationincreaseN/A N/A N/A 2.8% 3.1% 3.0% N/A N/A N/A42The weighted average assumptions used to determine net periodic benefit cost for the years ended December 31, 2017, 2016 and 2015 were as follows: Pension Post-retirement U.S. International 2017 2016 2015 2017 2016 2015 2017 2016 2015Discount rate3.8% 4.6% 4.2% 2.3% 3.7% 3.4% 3.4% 3.9% 3.7%Expected long-term rate ofreturn7.8% 7.8% 8.0% 5.5% 6.0% 6.5% N/A N/A N/ARate of compensationincreaseN/A N/A N/A 3.1% 3.0% 3.0% N/A N/A N/AIn 2018, we expect pension income of approximately $4.9 million and post-retirement income of approximately $0.2 million.A 25-basis point change (0.25%) in our discount rate assumption would lead to an increase or decrease in our pension and post-retirement expense ofapproximately $0.002 million for 2018. A 25-basis point change (0.25%) in our long-term rate of return assumption would lead to an increase or decrease inpension and post-retirement expense of approximately $1.6 million for 2018.Pension and post-retirement liabilities of $275.5 million as of December 31, 2017 increased from $98.0 million at December 31, 2016, primarily due tothe Esselte Acquisition.Income TaxesDeferred tax liabilities or assets are established for temporary differences between financial and tax reporting bases and are subsequently adjusted toreflect changes in tax rates expected to be in effect when the temporary differences reverse. A valuation allowance is recorded to reduce deferred tax assets toan amount that is more likely than not to be realized. Facts and circumstances may change and cause us to revise the conclusions on our ability to realizecertain net operating losses and other deferred tax attributes.The amount of income taxes that we pay is subject to ongoing audits by federal, state and foreign tax authorities. Our estimate of the potential outcomeof any uncertain tax position is subject to management’s assessment of relevant risks, facts and circumstances existing at that time. We believe that we haveadequately provided for reasonably foreseeable outcomes related to these matters. However, our future results may include favorable or unfavorableadjustments to our estimated tax liabilities in the period any assessments are received, revised or resolved.On December 22, 2017, the U.S. Tax Act was signed into law. The U.S. Tax Act makes broad and complex changes to the U.S. tax code, including, butnot limited to: (i) reducing the future U.S. federal corporate tax rate from 35 percent to 21 percent; (ii) requiring companies to pay a one-time transition tax oncertain undistributed earnings of foreign subsidiaries; and (iii) bonus depreciation that will allow for full expensing of qualified property.The undistributed earnings of all non-U.S. subsidiaries were approximately $500 million as of December 31, 2017. All of the undistributed earningshave become subject to U.S. income taxes due to the enactment of the U.S. Tax Act in 2017. As a result of the U.S. Tax Act, we are analyzing the globalworking capital and cash requirements, and potential tax liabilities attributable to future repatriation of cash, but we have yet to determine whether we plan tochange our prior indefinite investment assertion under ASC 740. We will record the effects of any change in prior assertions in the period in which the changeoccurs.Due to the complexity of the global intangible low-taxed income ("GILTI") tax rules recently enacted by the U.S. Tax Act, the Company continues toanalyze this provision and its impact and the proper application of ASC 740. Under GAAP, the Company is allowed to make an accounting policy choice toeither treat the taxes due on future U.S. inclusions in taxable income related to GILTI as a current period expense when incurred (the "period cost method") orfactor in such amounts in to the Company’s measurement of deferred taxes (the "deferred method"). The Company’s selection of an accounting policy inconnection with GILTI depends upon additional analysis and potential future modifications to the existing structure, which are yet to be known.Accordingly, the Company has not recorded any adjustments related to GILTI in our financial statements and has not made a policy choice regarding whetherto record deferred taxes on GILTI.43For further information on the U.S. Tax Act, see "Note 11. Income Taxes" to the consolidated financial statements contained in Item 8. of this report.Recent Accounting Standards Updates and Recently Adopted Accounting StandardsFor information on recent accounting pronouncements, see "Note 2. Significant Accounting Policies" to the consolidated financial statementscontained in Item 8. of this report.ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKOur industry has historically been concentrated in a small number of major customers, primarily large regional resellers of our products includingtraditional office suppliers, retailers, e-tailers and wholesalers. Customer consolidation, shifts in the channels of distribution for our products and sharegrowth of private-label products continue to increase pricing pressures, which may adversely affect margins for our competitors and for us. We are addressingthese challenges through strong end-user brands, broader product penetration within categories, ongoing introduction of innovative new products,continuing improvements in customer service and diversification of our customer base, as well as continued cost and asset reductions.We are exposed to various market risks, including changes in foreign currency exchange rates and interest rate changes. We enter into financialinstruments to manage and reduce the impact of these risks, not for trading or speculative purposes. The counterparties to these financial instruments aremajor financial institutions.See also "Item 1A. Risk Factors."Foreign Exchange Risk ManagementWe enter into forward foreign currency contracts to reduce the effect of fluctuating foreign currencies, primarily on foreign denominated inventorypurchases and intercompany loans. The majority of the Company’s exposure to local currency movements is in Europe (the Euro, the Swedish krona and theBritish pound), Australia, Canada, Brazil, and Mexico. Principal currencies hedged include the U.S. dollar, Euro, Australian dollar, Canadian dollar, Swedishkrona, British pound and Japanese yen. Increases and decreases in the fair market values of our forward agreements are expected to be offset by gains/losses inrecognized net underlying foreign currency transactions or loans. Notional amounts of outstanding foreign currency forward exchange contracts were $188.5million and $128.6 million at December 31, 2017 and 2016, respectively. The net fair value of these foreign currency contracts was $(0.3) million and $4.1million at December 31, 2017 and 2016, respectively. At December 31, 2017, a 10% unfavorable exchange rate movement in our portfolio of foreigncurrency forward contracts would have reduced our unrealized gains by $20.1 million. Consistent with the use of these contracts to neutralize the effect ofexchange rate fluctuations, such unrealized losses or gains would be offset by corresponding gains or losses, respectively, in the remeasurement of theunderlying transactions being hedged. When taken together, we believe these forward contracts and the offsetting underlying commitments do not creatematerial market risk.For further information related to outstanding foreign currency forward exchange contracts, see "Note 13. Derivative Financial Instruments" and "Note14. Fair Value of Financial Instruments" to the consolidated financial statements contained in Item 8. of this report.For our most recent acquisitions (the PA and Esselte Acquisitions), we have taken on additional debt in the local currency of the targets to reduce ourforeign exchange leverage risk. In the case of the PA Acquisition, which primarily conducts its business in the Australian dollar, we borrowed A$100.0million. For the Esselte Acquisition, completed on January 31, 2017, which primarily conducts its business in the Euro, we borrowed €300.0 million. Forfurther information see, "Note 3. Acquisitions" and "Note 4. Long-term Debt and Short-term Borrowings" to the consolidated financial statements containedin Item 8. of this report.44Interest Rate Risk ManagementAmounts outstanding under the 2017 Credit Agreement bear interest at a rate per annum equal to the Euro Rate, with a 0% floor, the Australian BBSRRate, the Canadian BA Rate or the Base Rate, as applicable and as each such rate is defined in the 2017 Credit Agreement, plus an "applicable rate." Theapplicable rate applied to outstanding Euro, Australian and Canadian dollar denominated loans and Base Rate loans is based on the Company’sConsolidated Leverage Ratio (as defined in the 2017 Credit Agreement) as follows:ConsolidatedLeverage Ratio Applicable Rate onEuro/AUD/CDN DollarLoans Applicable Rate on BaseRate Loans> 4.00 to 1.00 2.50% 1.50%≤ 4.00 to 1.00 and > 3.50 to 1.00 2.25% 1.25%≤ 3.50 to 1.00 and > 3.00 to 1.00 2.00% 1.00%≤ 3.00 to 1.00 and > 2.00 to 1.00 1.50% 0.50%≤ 2.00 to 1.00 1.25% 0.25%As of December 31, 2017, the applicable rate on Euro, Australian and Canadian dollar loans was 1.50% and the applicable rate on Base Rate loans was0.50%. Undrawn amounts under the 2017 Revolving Facility are subject to a commitment fee rate of 0.25% to 0.40% per annum, depending on theCompany’s Consolidated Leverage Ratio. As of December 31, 2017, the commitment fee rate was 0.30%.The New Notes have a fixed interest rate and, accordingly, are not exposed to market risk resulting from changes in interest rates. However, the fairmarket value of our long-term fixed interest rate debt is subject to interest rate risk. Generally, the fair market value of fixed interest rate debt will increase asinterest rates fall and decrease as interest rates rise. In addition, fair market values will also reflect the credit markets' view of credit risk spreads and our riskprofile. These interest rate changes may affect the fair market value of our fixed interest rate debt and any repurchases of these New Notes, but do not impactour earnings or cash flows.The following table summarizes information about our major debt components as of December 31, 2017, including the principal cash payments andinterest rates.Debt Obligations Stated Maturity Date (in millions of dollars)2018 2019 2020 2021 2022 Thereafter Total Fair ValueLong term debt: Fixed rate Senior Unsecured Notes, dueDecember 2024$— $— $— $— $— $400.0 $400.0 $412.0Fixed interest rate 5.25% Variable rate Euro Senior Secured TermLoan A, due January 2022$24.6 $33.6 $42.6 $44.8 $199.4 $— $345.0 $345.0Variable rate Australian Dollar SeniorSecured Term Loan A, due January2022$4.3 $5.8 $7.4 $7.8 $34.7 $— $60.0 $60.0Variable rate U.S. Dollar Senior SecuredRevolving Credit Facility, due January2022$13.9 $— $— $— $35.0 $— $48.9 $48.9Variable rate Australian Dollar SeniorSecured Revolving Credit Facility, dueJanuary 2022$— $— $— $— $85.0 $— $85.0 $85.0Average variable interest rate(1)2.16% 2.16% 2.16% 2.16% 2.16% (1)Rates presented are as of December 31, 2017.45ITEM 8.

We also have audited theCompany’s internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control - Integrated Framework (2013) issued by theCommittee of Sponsoring Organizations of the Treadway Commission.In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and2016, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2017, in conformity with U.S. generally acceptedaccounting principles. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based oncriteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.Basis for OpinionsThe Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment ofthe effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility isto express an opinion on the Company’s consolidated financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are apublic accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Companyin accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance aboutwhether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting wasmaintained in all material respects.Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether dueto error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in theconsolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overallpresentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financialreporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Ouraudits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.Definition and Limitations of Internal Control Over Financial ReportingA company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation offinancial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policiesand 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 accountingprinciples, 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) providereasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on thefinancial 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 futureperiods 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 maydeteriorate.[/s/ KPMG LLP]We have served as the Company’s auditor since 2009.Chicago, IllinoisFebruary 28, 201847ACCO Brands Corporation and SubsidiariesConsolidated

Basis of PresentationAs used in this Annual Report on Form 10-K for the fiscal year ended December 31, 2017, the terms "ACCO Brands," "ACCO," the "Company," "we,""us," and "our" refer to ACCO Brands Corporation, a Delaware corporation incorporated in 2005, and its consolidated domestic and international subsidiaries.The management of ACCO Brands Corporation is responsible for the accuracy and internal consistency of the preparation of the consolidated financialstatements and notes contained in this Annual Report on Form 10-K.The consolidated financial statements include the accounts of ACCO Brands Corporation and its domestic and international subsidiaries. Intercompanyaccounts and transactions have been eliminated in consolidation.On January 31, 2017, the Company completed the acquisition (the "Esselte Acquisition") of Esselte Group Holdings AB ("Esselte"). Accordingly, thefinancial results of Esselte are included in the Company's condensed consolidated financial statements as of February 1, 2017, and are reflected in all three ofthe Company's reportable segments. See "Note 3. Acquisitions" for details on the Esselte Acquisition.Effective with the first quarter of 2017, as a result of the Esselte Acquisition, the Company realigned its operating structure, which impacted itsdetermination of its business segments for financial reporting purposes. As a result, the Company no longer reports the financial results of its ComputerProducts Group as a separate segment. Prior year amounts included herein have been restated to conform to the current year presentation. See "Note 16.Information on Business Segments" for details on the realigned segments.On May 2, 2016, the Company completed the acquisition of Australia Stationery Industries, Inc. (the "PA Acquisition"), which indirectly owned the50% of the Pelikan Artline joint-venture and the issued capital stock of Pelikan Artline Pty Limited (collectively, "Pelikan Artline") that was not alreadyowned by the Company. Prior to the PA Acquisition, the Pelikan Artline joint-venture was accounted for under the equity method. From the date of the PAAcquisition, the results of Pelikan Artline are included in the Company's consolidated financial statements and are reported in the ACCO BrandsInternational segment. Accordingly, we no longer separately report equity in earnings from this joint venture. See "Note 3. Acquisitions" for details on the PAAcquisition.The preparation of financial statements in conformity with generally accepted accounting principles in the U.S. ("GAAP") requires management tomake certain estimates and assumptions that affect the reported assets and liabilities at the date of the financial statements and the reported revenues andexpenses during the reporting periods. Actual results could differ from those estimates.2. Significant Accounting PoliciesNature of BusinessACCO Brands is a designer, marketer and manufacturer of recognized consumer and end-user demanded brands used in businesses, schools, and homes.ACCO Brands has three operating business segments each of which is comprised of different geographic regions. Each of the Company's three operatingsegments designs, markets, sources, manufactures and sells recognized consumer and end-user demanded brands used in businesses, schools and homes.Product designs are tailored based on end-user preferences in each geographic region.Our product categories include storage and organization; stapling; punching; laminating, binding and shredding machines and related consumablesupplies; whiteboards; notebooks; calendars; computer accessories; and do-it-yourself tools, among others. Our portfolio of consumer and end-userdemanded brands includes both globally and regionally recognized brands.ACCO Brands markets and sells its strong multi-product offering broadly and is not dependent on any one channel. Our products are sold through allrelevant channels, namely retailers, including: mass retailers; e-tailers; discount, drug/grocery and variety chains; warehouse clubs; hardware and specialtystores; independent office product dealers; office superstores; and contract53ACCO Brands Corporation and SubsidiariesNotes to Consolidated Financial Statements (Continued)stationers. We also sell directly to commercial and consumer end-users through our e-commerce platform and our direct sales organization.Use of EstimatesThe preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reportedamounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts ofrevenues and expenses during the reporting period. Actual results could differ from these estimates.Cash and Cash EquivalentsHighly liquid investments with an original maturity of three months or less are included in cash and cash equivalents.Allowances for Doubtful Accounts, Discounts and ReturnsTrade receivables are recorded at the stated amount, less allowances for discounts, doubtful accounts and returns. The allowance for doubtful accountsrepresents estimated uncollectible receivables associated with potential customer defaults on contractual obligations, usually due to a customer's potentialinsolvency. The allowance includes amounts for certain customers where a risk of default has been specifically identified. In addition, the allowance includesa provision for customer defaults on a general formulaic basis when it is determined the risk of some default is probable and estimable, but cannot yet beassociated with a specific customer. The assessment of the likelihood of customer defaults is based on various factors, including the length of time thereceivables are past due, historical experience and existing economic conditions.The allowance for sales returns represents estimated uncollectible receivables associated with the potential return of products previously sold tocustomers, and is recorded at the same time that the sales are recognized. The allowance includes a general provision for product returns based on historicaltrends. In addition, the allowance includes a reserve for currently authorized customer returns that are considered to be abnormal in comparison to thehistorical basis.InventoriesInventories are priced at the lower of cost (principally first-in, first-out with minor amounts at average) or net realizable value. Inventory reserves arerecorded for obsolete or slow-moving inventory based on assumptions about future demand and marketability of products, the impact of new productintroductions and specific identification of items, such as product discontinuance or engineering/material changes. These estimates could vary significantly,either favorably or unfavorably, from actual requirements if future economic conditions, customer inventory levels or competitive conditions differ from ourexpectations.Property, Plant and EquipmentProperty, plant and equipment are carried at cost. Depreciation is provided, principally on a straight-line basis, over the estimated useful lives of theassets. Gains or losses resulting from dispositions are included in operating income. Betterments and renewals, which improve and extend the life of an assetare capitalized; maintenance and repair costs are expensed. Purchased computer software is capitalized and amortized over the software’s useful life. Thefollowing table shows estimated useful lives of property, plant and equipment:Property, plant and equipment Useful LifeBuildings 40 to 50 yearsLeasehold improvements Lesser of lease term or the life of the assetMachinery, equipment and furniture 3 to 10 yearsComputer software 5 to 10 yearsWe capitalize interest for major capital projects. Capitalized interest is added to the cost of the underlying assets and is depreciated over the useful livesof those assets. We capitalized interest of $0.1 million, $0.1 million and $1.3 million for the years ended December 31, 2017, 2016 and 2015, respectively.54ACCO Brands Corporation and SubsidiariesNotes to Consolidated Financial Statements (Continued)Long-Lived AssetsWe test long-lived assets for impairment whenever events or changes in circumstances indicate that the assets’ carrying amount may not be recoverablefrom its undiscounted cash flow. When such events occur, we compare the sum of the undiscounted cash flow expected to result from the use and eventualdisposition of the asset or asset group to the carrying amount of a long-lived asset or asset group. The cash flows are based on our best estimate at the time offuture cash flow, derived from the most recent business projections. If this comparison indicates that there is an impairment, the amount of the impairment istypically calculated using discounted expected future cash flow. The discount rate applied to these cash flows is based on our weighted average cost ofcapital, computed by selecting market rates at the valuation dates for debt and equity that are reflective of the risks associated with an investment in ourindustry as estimated by using comparable publicly traded companies.Intangible AssetsIntangible assets are comprised primarily of indefinite-lived and amortizable intangible assets acquired and arising from the application of purchaseaccounting. Indefinite-lived intangible assets are not amortized, but are evaluated at least annually to determine whether the indefinite useful life isappropriate. In addition, amortizable intangible assets other than goodwill are amortized over their useful lives. Certain of our trade names have beenassigned an indefinite life as we currently anticipate that these trade names will contribute cash flows to ACCO Brands indefinitely.We test indefinite-lived intangibles for impairment at least annually, normally in the second quarter, and whenever market or business events indicatethere may be a potential adverse impact on a particular intangible. The review may be on a qualitative ("Step-Zero") or quantitative ("Step-1") basis asallowed by GAAP. We consider the implications of both external factors (e.g., market growth, pricing, competition, and technology) and internal factors (e.g.,product costs, margins, support expenses, and capital investment) and their potential impact on cash flows in both the near and long term, as well as theirimpact on any identifiable intangible asset associated with the business. Based on recent business results, consideration of significant external and internalfactors, and the resulting business projections, indefinite-lived intangible assets are reviewed to determine whether they are likely to remain indefinite-lived,or whether a finite life is more appropriate. In addition, based on events in the period and future expectations, management considers whether the potentialfor impairment exists. Finite lived intangibles are amortized over 10, 15, 23 or 30 years.We performed our annual assessment, on a qualitative basis, as allowed by GAAP, for the majority of our indefinite-lived trade names in the secondquarter of 2017 and concluded that no impairment existed. For two of our indefinite-lived trade names that are not substantially above their carrying values,Mead® and Hilroy®, we performed Step-1 tests in the second quarter of 2017. The following long-term growth rates and discount rates were used, 1.5% and10.5% for Mead®, and 1.5% and 11.0% for Hilroy®, respectively. We concluded that neither the Mead® nor Hilroy® trade names were impaired. The fair valueof the Mead® trade name was less than 30% above its carrying value as of the second quarter of 2017 Step-1 test. As of December 31, 2017, the carrying valueof the Mead® trade name was $113.3 million.As of June 1, 2017, we changed the indefinite-lived Hilroy® trade name to an amortizable intangible asset. The change was made as a result of decisionsregarding the Company's future use of the trade name. The Company commenced amortizing the Hilroy trade name June 1, 2017 on a straight-line basis overa life of 30 years.GoodwillGoodwill has been recorded on our balance sheet and represents the excess of the cost of an acquisition when compared to the fair value of the netassets acquired. The authoritative guidance on goodwill and other intangible assets requires that goodwill be tested for impairment at a reporting unit level.We have determined that our reporting units are ACCO Brands North America, ACCO Brands EMEA and ACCO Brands International.We test goodwill for impairment at least annually and whenever events or circumstances make it more likely than not that an impairment may haveoccurred. As permitted by GAAP, we may perform a qualitative assessment ("Step-Zero") to determine if it is more likely than not that the fair value of areporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform a quantitative goodwill impairment test ("Step-1")as required by GAAP. We performed our annual assessment in the second quarter of 2017, on a qualitative basis, and concluded that it was not more likelythan not that the fair value of any reporting unit is less than its carrying amount.55ACCO Brands Corporation and SubsidiariesNotes to Consolidated Financial Statements (Continued)If the qualitative assessment determines that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, or if it isdetermined that a qualitative assessment is not appropriate, we move onto the quantitative goodwill ("Step-1") impairment test where we calculate the fairvalue of the reporting units. When applying a fair-value-based test, the fair value of a reporting unit is compared to its carrying value. If the fair value of areporting unit exceeds the carrying value of the net assets assigned to a reporting unit, goodwill is considered not impaired and no further testing is required.If the carrying value of the net assets assigned to a reporting unit exceeds the fair value of a reporting unit, an impairment charge is recognized, however, theloss recognized is not to exceed the total amount of goodwill allocated to the reporting unit.Employee Benefit PlansWe provide a range of benefits to our employees and retired employees, including pension, post-retirement, post-employment and health care benefits.We record annual amounts relating to these plans based on calculations specified by GAAP, which include various actuarial assumptions, including discountrates, assumed rates of return, compensation increases, turnover rates and health care cost trend rates. Actuarial assumptions are reviewed on an annual basisand modifications to these assumptions are made based on current rates and trends when it is deemed appropriate. As required by GAAP, the effect of ourmodifications are generally recorded and amortized over future periods.Income TaxesDeferred tax liabilities or assets are established for temporary differences between financial and tax reporting bases and are subsequently adjusted toreflect changes in tax rates expected to be in effect when the temporary differences reverse. A valuation allowance is recorded to reduce deferred tax assets toan amount that is more likely than not to be realized. Facts and circumstances may change and cause us to revise the conclusions on our ability to realizecertain net operating losses and other deferred tax attributes.The amount of income taxes that we pay is subject to ongoing audits by federal, state and foreign tax authorities. Our estimate of the potential outcomeof any uncertain tax position is subject to management’s assessment of relevant risks, facts and circumstances existing at that time. We believe that we haveadequately provided for reasonably foreseeable outcomes related to these matters. However, our future results may include favorable or unfavorableadjustments to our estimated tax liabilities in the period any assessments are received, revised or resolved.On December 22, 2017, the U.S. Tax Act was signed into law. The U.S. Tax Act makes broad and complex changes to the U.S. tax code, including, butnot limited to: (i) reducing the future U.S. federal corporate tax rate from 35 percent to 21 percent; (ii) requiring companies to pay a one-time transition tax oncertain undistributed earnings of foreign subsidiaries; and (iii) bonus depreciation that will allow for full expensing of qualified property.The undistributed earnings of all non-U.S. subsidiaries were approximately $500 million as of December 31, 2017. All of the undistributed earningshave become subject to U.S. income taxes due to the enactment of the U.S. Tax Act in 2017. As a result of the U.S. Tax Act, we are analyzing the globalworking capital and cash requirements, and potential tax liabilities attributable to future repatriation of cash, but we have yet to determine whether we plan tochange our prior indefinite investment assertion under ASC 740. We will record the effects of any change in prior assertions in the period in which the changeoccurs.Due to the complexity of the global intangible low-taxed income ("GILTI") tax rules recently enacted by the U.S. Tax Act, the Company continues toanalyze this provision and its impact and the proper application of ASC 740. Under GAAP, the Company is allowed to make an accounting policy choice toeither treat the taxes due on future U.S. inclusions in taxable income related to GILTI as a current period expense when incurred (the "period cost method") orfactor in such amounts in to the Company’s measurement of deferred taxes (the "deferred method"). The Company’s selection of an accounting policy inconnection with GILTI depends upon additional analysis and potential future modifications to the existing structure, which are yet to be known.Accordingly, the Company has not recorded any adjustments related to GILTI in our financial statements and has not made a policy choice regarding whetherto record deferred taxes on GILTI.For further information on the U.S. Tax Act, see "Note 11. Income Taxes" to the consolidated financial statements contained in Item 8. of this report.56ACCO Brands Corporation and SubsidiariesNotes to Consolidated Financial Statements (Continued)Revenue RecognitionWe recognize revenue from product sales when earned, net of applicable provisions for discounts, returns and allowances. We consider revenue to berealized or realizable and earned when all of the following criteria are met: title and risk of loss have passed to the customer, persuasive evidence of anarrangement exists, delivery has occurred, the price is fixed or determinable and collectability is reasonably assured. We also provide our estimate ofpotential bad debt concurrent with recognizing revenue.Customer Program CostsCustomer program costs include, but are not limited to, sales rebates, which are generally tied to achievement of certain sales volume levels, in-storepromotional allowances, shared media and customer catalog allowances and other cooperative advertising arrangements, and freight allowance programs. Wegenerally recognize customer program costs as a deduction to gross sales at the time that the associated revenue is recognized. Certain customer incentivesthat do not directly relate to future revenues are expensed when initiated.In addition, accrued customer program liabilities principally include, but are not limited to, sales volume rebates, promotional allowances, sharedmedia and customer catalog allowances and other cooperative advertising arrangements and freight allowances.Cost of Products SoldCost of products sold includes all manufacturing, product sourcing and distribution costs, including depreciation related to assets used in themanufacturing, procurement and distribution process, allocation of certain information technology costs supporting those processes, inbound and outboundfreight, shipping and handling costs, purchasing costs associated with materials and packaging used in the production processes.Selling, General and Administrative ExpensesSelling, general and administrative expenses ("SG&A") include advertising, marketing, selling (including commissions), research and development,customer service, depreciation related to assets outside the manufacturing and distribution processes and all other general and administrative expensesoutside the manufacturing and distribution functions (e.g., finance, human resources, information technology, and corporate expenses).Advertising CostsAdvertising costs amounted to $114.8 million, $110.1 million and $120.9 million for the years ended December 31, 2017, 2016 and 2015,respectively. These costs primarily include, but are not limited to, cooperative advertising and promotional allowances as described in "Customer ProgramCosts" above, and are principally expensed as incurred.Shipping and HandlingWe reflect all amounts billed to customers for shipping and handling in net sales and the costs incurred from shipping and handling product (includingcosts to ship and move product from the seller’s place of business to the buyer’s place of business, as well as costs to store, move and prepare products forshipment) in cost of products sold.Warranty ReservesWe offer our customers various warranty terms based on the type of product that is sold. Estimated future obligations related to products sold underthese warranty terms are provided by charges to cost of products sold in the same period in which the related revenue is recognized.Research and DevelopmentResearch and development expenses, which amounted to $23.5 million, $21.0 million and $20.0 million for the years ended December 31, 2017, 2016and 2015, respectively, are classified as SG&A expenses and are charged to expense as incurred.57ACCO Brands Corporation and SubsidiariesNotes to Consolidated Financial Statements (Continued)Stock-Based CompensationOur primary types of share-based compensation consist of stock options, restricted stock unit awards and performance stock unit awards. Stock-basedcompensation cost is measured at the grant date, based on the fair value of the award, and is recognized as expense over the requisite service period. Whereawards are made with non-substantive vesting periods (for example, where a portion of the award vests due to retirement eligibility), we estimate andrecognize expense based on the period from the grant date to the date on which the employee is retirement eligible. Effective in 2017, the Company made theaccounting policy election to account for forfeitures as they occur, which affects the timing of stock compensation expense. See "Recently AdoptedAccounting Standards" below for details.Foreign Currency TranslationForeign currency balance sheet accounts are translated into U.S. dollars at the rates of exchange at the balance sheet date. Income and expenses aretranslated at the average rates of exchange in effect during the period. The related translation adjustments are made directly to a separate component ofaccumulated other comprehensive income (loss) ("AOCI") in stockholders’ equity. Some transactions are made in currencies different from an entity’sfunctional currency. Gains and losses on these foreign currency transactions are included in income as they occur.Derivative Financial InstrumentsWe recognize all derivatives as either assets or liabilities on the balance sheet and record those instruments at fair value. If the derivative is designatedas a fair value hedge and is effective, the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are recognized inearnings in the same period. If the derivative is designated as a cash flow hedge, the effective portions of changes in the fair value of the derivative arerecorded in AOCI and are recognized in the Consolidated Statements of Income when the hedged item affects earnings. Ineffective portions of changes in thefair value of cash flow hedges are recognized in earnings.Certain forecasted transactions, assets and liabilities are exposed to foreign currency risk. We continually monitor our foreign currency exposures inorder to maximize the overall effectiveness of our foreign currency hedge positions. Principal currencies hedged include the U.S. dollar, Euro, Australiandollar, Canadian dollar, Swedish krona, British pound and Japanese yen.Recent Accounting Standards UpdatesIn May 2014 the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update (ASU) No. 2014-09, Revenue fromContracts with Customers (Topic 606), which supersedes substantially all existing revenue recognition requirements, including most industry-specificguidance. The new standard requires a company to recognize revenue when it transfers goods or services to customers in an amount that reflects theconsideration that the company expects to receive for those goods or services. The FASB has subsequently issued the following amendments to ASU 2014-09, which have the same effective date and transition date of January 1, 2018:•In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, whichdelayed the effective date of the new standard from January 1, 2017 to January 1, 2018. The FASB also agreed to allow entities to choose to adoptthe standard as of the original effective date.•In March 2016, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations,which clarifies the implementation guidance on principal versus agent considerations.•In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations andLicensing, which clarifies certain aspects of identifying performance obligations and licensing implementation guidance.•In May 2016, the FASB issued ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and PracticalExpedients related to disclosures of remaining performance obligations, as well as other amendments to guidance on collectability, non-cashconsideration and the presentation of sales and other similar taxes collected from customers.58ACCO Brands Corporation and SubsidiariesNotes to Consolidated Financial Statements (Continued)•In December 2016, the FASB issued ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts withCustomers, which amends certain narrow aspects of the guidance issued in ASU 2014-09, including guidance related to the disclosure of remainingperformance obligations and prior-period performance obligations, as well as other amendments to the guidance on loan guarantee fees, contractcosts, refund liabilities, advertising costs and the clarification of certain examples.The Company analyzed the impact of ASU 2014-09 across all of its revenue streams. This included reviewing current accounting policies and practicesto identify potential differences that would result from applying the requirements under the new standard. The Company also completed contract reviews andvalidated the results of applying the new revenue guidance. Upon the implementation of ASU 2014-09, the Company expects to accelerate the timing ofsome of its revenue recognition with respect to its customer contracts for private label and customized products. This acceleration of revenue would only befor contracts where a right to payment exists and there is no alternative use for the product, as prescribed by ASU 2014-09.The Company will adopt the new standard using the modified retrospective approach, under which the cumulative effect of initially applying the newguidance will be recognized as an adjustment to the opening balance of retained earnings in the first quarter of 2018. The Company expects to record anincrease to its opening balance of retained earnings of approximately $1.6 million, net of tax effect, in the first quarter ending March 31, 2018.The Company is also in the process of updating its controls and systems, and is still finalizing its new disclosures required in 2018.In February 2018, the FASB issued ASU No. 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220). In December 2017, the U.S.Tax Act was signed into law. Prior to ASU 2018-02, GAAP required deferred tax assets and deferred tax liabilities to be adjusted for the effect of a change intax laws or rates with the effect included in income from continuing operations in the reporting period including the enactment date. The U.S. Tax Actreduces the historical U.S corporate tax rate and the effect of that change is required to be included in income from continuing operations, even if the originaltax effects were recorded in Accumulated Other Comprehensive Income ("AOCI"). This could cause some tax effects to become stranded in AOCI as they arenot updated to reflect the new tax rate. This new standard allows a company to elect to reclass the stranded tax effects resulting from the U.S. Tax Act fromAOCI to retained earnings. The adoption of the new standard may be applied in the period of adoption or retrospectively to each period(s) effected by thechange in the corporate tax rate. The Company is currently in the process of evaluating the impact of adoption of ASU 2018-02 on the Company’sconsolidated financial statements. ASU 2018-02 is effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2018.Early adoption of the standard is permitted including adoption in any interim period for which financial statements have not been issued.In August 2017, the FASB issued ASU No. 2017-12, Derivative and Hedging (Topic 815), Targeted Improvements to Accounting for HedgingActivities. The new standard improves certain aspects of the hedge accounting model, including making more risk management strategies eligible for hedgeaccounting and simplifying the assessment of hedge effectiveness. The Company is currently in the process of assessing the impact of adoption of ASU 2017-12 on the Company's consolidated financial statements. The Company will adopt ASU 2017-12 effective with its 2019 fiscal year.In March 2017, the FASB issued ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net PeriodicPension Cost and Net Periodic Postretirement Benefit Cost. The new standard requires presentation of all components of net periodic pension andpostretirement benefit costs, other than service costs, in an income statement line item outside of a subtotal of income from operations. The service costcomponent will continue to be presented in the same line item as other employee compensation costs. In addition, the guidance allows only service costs tobe eligible for capitalization. The guidance is required to be adopted retrospectively with respect to the income statement requirement and prospectively forthe capitalization requirement. We do not expect the change in the capitalization requirement to have a material effect on our financial statements, but it isexpected to have a material effect on our operating income. The Company will use the practical expedient that permits an employer to use the amountsdisclosed in "Note 5. Pension and Other Retiree Benefits" as the basis for applying the retrospective presentation requirements. On this basis, the Company'soperating income for the years ended December 31, 2017 and 2016 would be reduced by approximately $8.4 million and $8.2 million, respectively. The newguidance is effective with the first quarter of the Company's 2018 fiscal year.In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). This new standard will require the recognition, on the balance sheet, of mostleases as lease assets (right-of-use assets) and lease liabilities by lessees for those leases classified as operating leases under current GAAP. Lease expense isrecorded on the income statement in a manner similar to current59ACCO Brands Corporation and SubsidiariesNotes to Consolidated Financial Statements (Continued)accounting. This new standard also includes increased disclosures to meet the objective of enabling users of financial statements to understand more aboutthe nature of an entity’s leasing activities. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods withinthose fiscal years. Early adoption is permitted and adoption of ASU 2016-02 is to be done on a modified retrospective basis. The Company is currently in theprocess of evaluating the impact of adoption of ASU 2016-02 on the Company’s consolidated financial statements and it currently expects that most of itsoperating lease commitments will be subject to the new standard and will be recognized as operating lease liabilities and right-of-use assets upon theadoption of ASU 2016-02. It is expected that these changes will be material to the Company's consolidated financial statements. The Company will adoptASU 2016-02 effective with its 2019 fiscal year.Other than the items mentioned above, there are no other recently issued accounting standards that are expected to have a material effect on theCompany’s financial condition, results of operations or cash flow.Recently Adopted Accounting StandardsIn March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-BasedPayment Accounting. This new standard simplifies the accounting for employee share-based payments and involves several aspects of the accounting forshare-based transactions, including the potential timing of expenses, the income tax consequences, classification of awards as either equity or liabilities andclassification on the statement of cash flows. ASU 2016-09 is effective for annual periods beginning after December 15, 2016, and interim periods withinthose annual periods. The Company adopted ASU 2016-09 effective with the first quarter of 2017. The Company made the allowed accounting policyelection to account for forfeitures as they occur, which affects the timing of stock compensation expense. The change in accounting of forfeitures, along withthe changes related to how excess tax benefits are recognized, has been done using a modified retrospective transition method by means of a cumulative-effect adjustment to equity as of the beginning of the first quarter of 2017, which was not material. An effect of the change was to require recognition ofexcess tax benefits in our Consolidated Statements of Income rather than as a component of equity under the previous standard; therefore, for the year endedDecember 31, 2017, a tax benefit of $5.6 million was recorded in the Company's Consolidated Statements of Income.In July 2015, the FASB issued ASU No. 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. This new standard applies toinventory that is measured using first-in, first-out (FIFO) or average cost. An entity should measure inventory within the scope of ASU 2015-11 at the lower ofcost or net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs ofcompletion, disposal and transportation. ASU 2015-11 is effective for fiscal years beginning after December 15, 2016. The Company adopted ASU 2015-11effective with the first quarter of 2017 and it had an immaterial effect on the Company's consolidated financial statements.3. AcquisitionsAcquisition of Esselte Group Holdings AB (the "Esselte Acquisition")On January 31, 2017, ACCO Europe Limited ("ACCO Europe"), an indirect wholly-owned subsidiary of the Company, completed the EsselteAcquisition. The Esselte Acquisition was made pursuant to the share purchase agreement, dated October 21, 2016, as amended (the "Purchase Agreement"),among ACCO Europe, the Company and an entity controlled by J. W. Childs ("Seller").With the acquisition of Esselte, ACCO Brands is a leading European manufacturer and marketer of branded business products. Esselte takes products tomarket under the Leitz®, Rapid® and Esselte® brands in the storage and organization, stapling, punching, business machines and do-it-yourself tools productcategories. The combination improved ACCO Brands’ scale and enhanced its position as an industry leader in Europe.The purchase price paid at closing was €302.9 million (US$326.8 million based on January 31, 2017 exchange rates) and was subject to a workingcapital adjustment that reduced it by $0.3 million. The purchase price, net of cash acquired of $34.2 million, was $292.3 million. A portion of the purchaseprice (€8.1 million (US$8.7 million based on January 31, 2017 exchange rates)) is being held in an escrow account for a period of up to two years afterclosing as ACCO Europe’s sole recourse against Seller in the event of any claims against Seller under the Purchase Agreement. A warranty and indemnityinsurance policy held by the Company and ACCO Europe insures certain of Seller’s contractual obligations to ACCO Europe under the Purchase Agreementfor up to €40.0 million (US$43.2 million based on January 31, 2017 exchange rates) for a period of up to seven years, subject to certain deductibles andlimitations set forth in the policy.60ACCO Brands Corporation and SubsidiariesNotes to Consolidated Financial Statements (Continued)The Esselte Acquisition and related expenses were funded through a term loan of €300.0 million (US$320.8 million based on January 27, 2017exchange rates) and cash on hand. See "Note 4. Long-term Debt and Short-term Borrowings" for details.For accounting purposes, the Company is the acquiring enterprise. The Esselte Acquisition is being accounted for as a purchase combination andEsselte's results are included in the Company’s condensed consolidated financial statements as of February 1, 2017. Esselte contributed $406.9 million of netsales for the year ended December 31, 2017.The following table presents the allocation of the consideration given to the fair values of the assets acquired and liabilities assumed at the date ofacquisition.(in millions of dollars)At January 31, 2017Calculation of Goodwill: Purchase price, net of working capital adjustment$326.5 Plus fair value of liabilities assumed: Accounts payable and accrued liabilities121.9Deferred tax liabilities83.6Pension obligations174.1Other non-current liabilities5.8 Fair value of liabilities assumed$385.4 Less fair value of assets acquired: Cash acquired34.2Accounts receivable60.0Inventory41.9Property, plant and equipment75.6Identifiable intangibles277.0Deferred tax assets106.3Other assets10.4 Fair value of assets acquired$605.4 Goodwill$106.5We have finalized our fair value estimate of assets acquired and liabilities assumed as of the acquisition date. No additional adjustments to the goodwillrelated to the Esselte Acquisition will be recognized.The excess of the purchase price over the fair value of net assets acquired is allocated to goodwill. The goodwill of $106.5 million is primarilyattributable to synergies expected to be realized from facility integration, headcount reduction and other operational streamlining activities, and from theexistence of an assembled workforce.During the fourth quarter of 2017, the previously estimated values for property, plant and equipment continued to be refined, which resulted inreductions in value of $2.4 million and we revised the depreciable life of certain assets. The impact to net income from this refinement in the first threequarters of 2017 would have been immaterial.For the years ended December 31, 2017 and 2016, transaction costs were $5.0 million and $9.2 million, respectively. These costs were reported asSG&A expenses.61ACCO Brands Corporation and SubsidiariesNotes to Consolidated Financial Statements (Continued)Unaudited Pro Forma Consolidated ResultsThe accounting literature establishes guidelines regarding, and requires the presentation of, the following unaudited pro forma information. Therefore,the unaudited pro forma information presented below is not intended to represent, nor do we believe it is indicative of, the consolidated results of operationsof the Company that would have been reported had the Esselte Acquisition been completed on January 1, 2016. Furthermore, the unaudited pro formainformation does not give effect to the anticipated synergies or other anticipated benefits of the Esselte Acquisition.Had the Esselte Acquisition occurred on January 1, 2016, unaudited pro forma consolidated results for the years ended December 31, 2017 and 2016would have been as follows: Year Ended December 31,(in millions of dollars, except per share data) 2017 2016Net sales $1,992.3 $2,006.3Net income 149.2 55.6Net income per common share (diluted) $1.35 $0.51The pro forma amounts are based on the Company's historical results and the historical results for the acquired Esselte business, which have beentranslated at the average foreign exchange rates for the periods presented. The pro forma results of operations have been adjusted for amortization of finite-lived intangibles, and other charges related to the Esselte Acquisition accounting. The pro forma results for the year ended December 31, 2016 have also beenadjusted to include transaction costs related to the Esselte Acquisition of $14.2 million and amortization of the purchase accounting step-up in inventorycost of $0.9 million.Acquisition of Australia Stationery Industries, Inc. (the "PA Acquisition")On May 2, 2016, the Company completed the PA Acquisition, purchasing the remaining 50% interest in the former Pelikan Artline joint-venture, whichit did not already own. Prior to the PA Acquisition, the Company's investment in the Pelikan Artline joint-venture was accounted for under the equitymethod. Pelikan Artline's product categories include writing instruments, notebooks, binding and lamination, visual communication, cleaning and janitorialsupplies, as well as general stationery. Its industry-leading brands include Artline®, Quartet®, GBC®, Spirax® and Texta®, among others.In the PA Acquisition, ACCO Brands Australia Pty Limited and Bigadale Pty Limited (collectively, ''ACCO Australia"), two wholly-owned indirectsubsidiaries of the Company, entered into a Share Sale Agreement (the "Agreement") with Andrew Kaldor, Cherington Investments Pty Ltd, FreiburgNominees Proprietary Limited, Enora Pty Ltd and Bruce Haynes and certain Guarantors named therein (collectively, the "Seller Parties") to purchase directlyor indirectly 100% of the capital stock of Australia Stationery Industries, Inc., which indirectly owned the 50% of the Pelikan Artline joint-venture and theissued capital stock of Pelikan Artline Pty Limited (collectively "Pelikan Artline") that was not already owned by ACCO Brands Australia Pty Limited.The purchase price was $103.7 million, net of working capital adjustments, and was $88.8 million, net of cash acquired.Following completion of the PA Acquisition, ACCO Australia owns, directly and indirectly, 100% of Pelikan Artline. In addition to representations,warranties and covenants, the Agreement contains indemnification obligations and certain non-competition and non-solicitation covenants made by theSeller Parties in favor of ACCO Australia. A portion of the purchase price was allocated to fund the redemption of a 19.83% minority interest from ashareholder of a subsidiary of Pelikan Artline (the "Minority Interest Redemption"), which occurred shortly following the closing of the PA Acquisition.Additionally, approximately 10% of the purchase price after deducting the Minority Interest Redemption is held in escrow as security with respect to post-closing warranty, tax claims and indemnification obligations.The Company financed the PA Acquisition through increased borrowings under its existing credit facility. See "Note 4. Long-term Debt and Short-termBorrowings" for details on these additional borrowings.For accounting purposes, the Company is the acquiring enterprise. The PA Acquisition was accounted for as a purchased business combination andPelikan Artline's results are included in the Company’s consolidated financial statements from the date of the PA Acquisition, May 2, 2016.62ACCO Brands Corporation and SubsidiariesNotes to Consolidated Financial Statements (Continued)The Company’s previously held equity interest in the Pelikan Artline joint-venture was remeasured to fair value at the date the controlling interest wasacquired. The fair value of the previously held equity interest in the Pelikan Artline joint-venture was determined by applying the income approach andusing significant inputs that market participants would consider, including: revenue growth rates, operating margins, a discount rate and an adjustment forlack of control. The $28.9 million excess of the fair value of the previously held equity interest when compared to the carrying value was recognized as again in "Other (income) expense, net” in the Consolidated Statements of Income.The calculation of consideration given in the PA Acquisition is described in the following table.(in millions of dollars)At May 2, 2016Purchase price, net of working capital adjustment$103.7Fair value of previously held equity interest69.3Consideration for Pelikan Artline$173.0The following table presents the allocation of the consideration given to the fair values of the assets acquired and liabilities assumed at the date of thePA Acquisition.(in millions of dollars)At May 2, 2016Calculation of Goodwill: Purchase price, net of working capital adjustment$103.7 Fair value of previously held equity interest69.3 Plus fair value of liabilities assumed: Accounts payable and accrued liabilities21.7Deferred tax liabilities0.2Debt24.7Other non-current liabilities1.4 Fair value of liabilities assumed$48.0 Less fair value of assets acquired: Cash acquired14.9Accounts receivable27.0Inventory24.1Property and equipment2.2Identifiable intangibles58.0Deferred tax assets5.7Other assets8.6 Fair value of assets acquired$140.5 Goodwill$80.5In the fourth quarter of 2016 we finalized our fair value estimate of assets acquired and liabilities assumed as of the acquisition date.

The goodwill of $80.5 million is primarilyattributable to synergies expected to be realized from facility integration, headcount reduction and other operational streamlining activities, and from theexistence of an assembled workforce.63ACCO Brands Corporation and SubsidiariesNotes to Consolidated Financial Statements (Continued)For the years ended December 31, 2016 and 2015, transaction costs related to the PA Acquisition were $1.3 million and $0.6 million, respectively.These costs were reported as SG&A expenses.4.

The Esselte Acquisition qualified as a MaterialAcquisition under the 2017 Credit Agreement.The 2017 Credit Agreement requires the Company to maintain a Consolidated Fixed Charge Coverage Ratio (as defined in the 2017 Credit Agreement)as of the end of any fiscal quarter at or above 1.25 to 1.00.As of December 31, 2017, our Consolidated Leverage Ratio was approximately 2.6 to 1 and our Fixed Charge Coverage Ratio was approximately 5.3 to1.Other Covenants and RestrictionsThe 2017 Credit Agreement contains customary affirmative and negative covenants as well as events of default, including payment defaults, breachof representations and warranties, covenant defaults, cross-defaults, certain bankruptcy or insolvency events, certain ERISA-related events, changes in controlor ownership and invalidity of any loan document.

The aggregateredemption price of $531.5 million consisted of principal due and payable on the Old Notes, a "make-whole" call premium of $25.0 million (included in"Other (income) expense, net"), and accrued and unpaid interest of $6.5 million (included in "Interest expense").66ACCO Brands Corporation and SubsidiariesNotes to Consolidated Financial Statements (Continued)Also included in "Other (income) expense, net" in 2016 was a $4.9 million charge for the write-off of debt issuance costs associated with the Old Notes.Additionally, we incurred and capitalized approximately $6.1 million in bank, legal and other fees associated with the issuance of the New Notes in 2016.Second Amended and Restated Credit AgreementDuring 2016, the Company’s credit facilities were governed by a Second Amended and Restated Credit Agreement, dated April 28, 2015 (assubsequently amended, the "2015 Credit Agreement"), among the Company, certain subsidiaries of the Company, Bank of America, N.A., as administrativeagent, and the other agents and lenders party thereto.The 2015 Credit Agreement provided for a $600.0 million five-year senior secured credit facility, which consisted of a $300.0 million revolving creditfacility (the "2015 Revolving Facility") and a $300.0 million term loan (the "2015 Term Loan A"). Borrowings under the 2015 Credit Agreement were dueApril 2020.In connection with the PA Acquisition, effective May 1, 2016, the Company entered into a Second Amendment and Additional Borrower Consent,among the Company, certain guarantor subsidiaries of the Company, Bank of America, N.A., as administrative agent, and the other lenders party thereto,which amended the 2015 Credit Agreement. Among other things, the Second Amendment amended the 2015 Credit Agreement to include ACCO BrandsAustralia Holding Pty. Ltd. ("ACCO Australia Holdings") as a foreign borrower and, together with a related incremental joinder agreement, facilitatedborrowings under the 2015 Credit Agreement by ACCO Australia Holdings.Financing of PA AcquisitionThe PA Acquisition, which closed in the second quarter of 2016, was financed through a borrowing under the 2015 Credit Agreement of A$100.0million (US$76.6 million based on May 2, 2016 exchange rates) by ACCO Australia Holdings in the form of an incremental Australian Dollar Senior SecuredTerm A loan, along with additional borrowings of A$152.0 million (US$116.4 million based on May 2, 2016 exchange rates) under the 2015 RevolvingFacility. The Company used some of the proceeds from the borrowings to reduce the U.S. Dollar Senior Secured Term Loan A due April 2020 by $78.0million and to pay off the debt assumed in the PA Acquisition of A$32.1 million (US$24.5 million based on May 2, 2016 exchange rates).Compliance with Loan CovenantsAs of and for the periods ended December 31, 2017 and December 31, 2016, the Company was in compliance with all applicable loan covenants.Guarantees and SecurityGenerally, obligations under the 2017 Credit Agreement and the 2015 Credit Agreement are and were guaranteed by certain of the Company's existingand future subsidiaries, and are and were secured by substantially all of the Company's and certain guarantor subsidiaries' assets, subject to certain exclusionsand limitations.The New Notes are irrevocably and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by each of our existing and futuredomestic subsidiaries other than certain excluded subsidiaries. The New Notes and the related guarantees will rank equally in right of payment with all of theexisting and future senior debt of the Company and the guarantors, senior in right of payment to all of the existing and future subordinated debt of theCompany and the guarantors, and effectively subordinated to all of the existing and future secured indebtedness of the Company and the guarantors to theextent of the value of the assets securing such indebtedness. The New Notes and the guarantees are and will be structurally subordinated to all existing andfuture liabilities, including trade payables, of each of the Company's subsidiaries that do not guarantee the notes.5. Pension and Other Retiree BenefitsWe have a number of pension plans, principally in Germany, the U.K. and the U.S. The plans provide for payment of retirement benefits, primarilycommencing between the ages of 60 and 65, and also for payment of certain disability and severance benefits. After meeting certain qualifications, anemployee acquires a vested right to future benefits. The benefits payable under the plans are generally determined based on an employee’s length of serviceand earnings. The majority of these plans have been frozen and67ACCO Brands Corporation and SubsidiariesNotes to Consolidated Financial Statements (Continued)are no longer accruing additional service benefits. Cash contributions to the plans are made as necessary to ensure legal funding requirements are satisfied.In the Esselte Acquisition, we acquired numerous pension plans, primarily in Germany and the U.K. The German plan, which is unfunded, is theprimarily driver of our increased pension liabilities compared to the prior-year period. The Esselte U.K. plan is frozen.On January 20, 2009, the Company’s Board of Directors approved plan amendments to temporarily freeze our ACCO Brands Corporation Pension Planfor Salaried and Certain Hourly Paid Employees in the U.S. (the "U.S. Salaried Plan") effective March 7, 2009. During the fourth quarter of 2014, the U.S.Salaried Plan became permanently frozen and, as of December 31, 2014, we have permanently frozen a portion of our U.S. pension plan for certain bargainedhourly employees.On September 30, 2012, our legacy U.K. pension plan was frozen. As of December 31, 2016, all of our Canadian pension plans were frozen.We also provide post-retirement health care and life insurance benefits to certain employee and retirees in the U.S., U.K. and Canada. All but one ofthese benefit plans have been frozen to new participants. Many employees and retirees outside of the U.S. are covered by government health care programs.68ACCO Brands Corporation and SubsidiariesNotes to Consolidated Financial Statements (Continued)The

Contributions are determined under various formulas. Costs related to such plans amounted to$13.4 million, $11.3 million and $9.8 million for the years ended December 31, 2017, 2016, and 2015, respectively. The increase of $2.1 million in definedcontribution plan costs in 2017 compared to 2016 is due to the Esselte Acquisition and additional matching contributions in the U.S. The $1.5 millionincrease in defined contribution plan costs in 2016 compared to 2015 was due to the PA Acquisition and additional matching contributions in the U.S.Multi-Employer Pension PlanWe are a participant in a multi-employer pension plan. The plan has reported significant underfunded liabilities and declared itself in critical anddeclining status (red). As a result, the trustees of the plan adopted a rehabilitation plan (RP) in an effort to forestall insolvency. Our required contributions tothis plan could increase due to the shrinking contribution base resulting from the insolvency of or withdrawal of other participating employers, from theinability or the failure of withdrawing participating employers to pay their withdrawal liability, from lower than expected returns on pension fund assets, andfrom other funding deficiencies. In the event that we withdraw from participation in the plan, we will be required to make withdrawal liability payments for aperiod of 20 years or longer in certain circumstances. The present value of our withdrawal liability payments would be recorded as an expense in ourConsolidated Statements of Income and as a liability on our Consolidated Balance Sheets in the first year of our withdrawal. The most recent PensionProtection Act (PPA) zone status available in 2017 and 2016 is for the plan’s years ended December 31, 2016 and 2015, respectively. The zone status is basedon information that we received from the plan and is certified by the plan’s actuary. Plans in the red zone are generally less than 65 percent funded, plans inthe yellow zone are less than 80 percent funded, and plans in the green zone are at least 80 percent funded.

Stock-Based CompensationThe ACCO Brands Corporation Incentive Plan (the "Plan") provides for stock based awards generally in the form of stock options, stock-settledappreciation rights ("SSARs"), restricted stock units ("RSUs") and performance stock units ("PSUs"), any of which may be granted alone or with other types ofawards and dividend equivalents. We have one share-based compensation plan under which a total of up to 13,118,430 shares may be issued under awards tokey employees and non-employee directors.Beginning in 2017, per ASU No. 2016-09 Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based PaymentAccounting, the Company made the allowed accounting policy election to account for forfeitures as they occur, which affects the timing of stockcompensation expense. Prior to 2017, forfeitures were estimated at the time of grant in order to calculate the amount of share-based payment awardsultimately expected to vest and the forfeiture rate was based on historical experience.We will satisfy the requirement for delivering shares of our common stock for our Plan by issuing new shares.The following table summarizes the impact of all stock-based compensation expense on our Consolidated Statements of Income for the years endedDecember 31, 2017, 2016 and 2015.(in millions of dollars)2017 2016 2015Selling, general and administrative expense$17.0 $19.4 $16.0Loss before income tax(17.0) (19.4) (16.0)Income tax benefit(6.1) (7.0) (5.7)Net loss$(10.9) $(12.4) $(10.3)There was no capitalization of stock-based compensation expense.75ACCO Brands Corporation and SubsidiariesNotes to Consolidated Financial Statements (Continued)Stock-based compensation expense by award type for the years ended December 31, 2017, 2016 and 2015 was as follows:(in millions of dollars)2017 2016 2015Stock option compensation expense$2.4 $2.9 $3.9RSU compensation expense4.3 4.5 4.7PSU compensation expense10.3 12.0 7.4Total stock-based compensation expense$17.0 $19.4 $16.0Stock Option and SSAR AwardsThe exercise price of each stock option equals or exceeds the fair market price of our stock on the date of grant. Options can generally be exercised overa maximum term of up to seven years. Stock options outstanding as of December 31, 2017 generally vest ratably over three years. In 2016, we did not grantany option awards. SSARs were last issued in 2009 and expired in 2016. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model and the weighted average assumptions as outlined in the following table: Year Ended December 31, 2017 2015Weighted average expected lives4.8years 4.5yearsWeighted average risk-free interest rate2.04% 1.47%Weighted average expected volatility39.7% 46.5%Expected dividend yield0.0% 0.0%Weighted average grant date fair value$4.70 $3.00 Volatility was calculated using ACCO Brands' historic volatility. The weighted average expected option term reflects ACCO Brands' historic life for alloption tranches beginning in 2017. Prior to 2017, the weighted average expected option term reflects the application of the simplified method, which definesthe life as the average of the contractual term of the option and the weighted average vesting period for all option tranches. The risk-free interest rate for theexpected term of the option is based on the U.S. Treasury yield curve in effect at the time of grant.A summary of the changes in stock options outstanding under the Plan during the year ended December 31, 2017 is presented below: NumberOutstanding WeightedAverageExercisePrice Weighted AverageRemainingContractual Term AggregateIntrinsicValueOutstanding at December 31, 20164,133,874 $7.82 Granted745,772 $12.75 Exercised(547,107) $7.72 Forfeited(59,888) $9.57 Outstanding at December 31, 20174,272,651 $8.68 3.3 years $15.5 millionExercisable shares at December 31, 20173,157,606 $7.88 2.6 years $13.6 millionWe received cash of $4.2 million, $6.8 million and $0.7 million from the exercise of stock options during the years ended December 31, 2017, 2016and 2015, respectively.

As of December 31, 2017, we had unrecognized compensation expense related to stock options of $2.7 million, which will be recognized over aweighted-average period of 1.5 years.Stock Unit AwardsRSUs vest over a pre-determined period of time, generally three years from the date of grant. Stock-based compensation expense for the years endedDecember 31, 2017, 2016 and 2015 includes $0.8 million, $0.9 million and $0.8 million, respectively, of expense that consisted of shares of stock (includedin RSU compensation expense) and RSUs granted to non-employee directors, which became fully vested on the grant date. PSUs also vest over a pre-determined period of time, minimally three years, but are further subject to the achievement of certain business performance criteria being met during thevesting period. Based upon the level of achieved performance, the number of shares actually awarded can vary from 0% to 150% of the original grant.There were 1,534,058 RSUs outstanding as of December 31, 2017. All outstanding RSUs as of December 31, 2017 vest within three years of their dateof grant. We generally recognize compensation expense for our RSU awards ratably over the service period. Also outstanding as of December 31, 2017 were3,531,312 PSUs. All outstanding PSUs as of December 31, 2017 vest at the end of their respective performance periods subject to the level of achievement ofthe performance targets associated with such awards. Upon vesting, all of the remaining RSU and PSU awards will be converted into the right to receive oneshare of common stock of the Company for each unit that vests. The cost of these awards is determined using the fair value of the shares on the date of grant,and compensation expense is generally recognized over the period during which the employee provides the requisite service to the Company. We generallyrecognize compensation expense for our PSU awards ratably over the performance period based on management’s judgment of the likelihood thatperformance measures will be attained.A summary of the changes in the RSUs outstanding under the Plan during 2017 is presented below: StockUnits WeightedAverageGrantDate FairValueOutstanding at December 31, 20161,910,669 $7.23Granted438,521 $12.65Vested and distributed(691,319) $6.21Vested and deferred distributed(38,042) $9.46Forfeited and cancelled(85,771) $8.66Outstanding at December 31, 20171,534,058 $9.10Vested and deferred at December 31, 2017(1)326,835 $9.16(1)Included in outstanding at December 31, 2017.

Amortization expense for software was $7.1 million,$7.0 million and $6.1 million for the years ended December 31, 2017, 2016 and 2015, respectively.The increase in net property, plant and equipment is primarily due to the Esselte Acquisition.9. Goodwill and Identifiable Intangible AssetsGoodwillEffective in the first quarter of 2017, as a result of the Esselte Acquisition, the Company realigned its operating structure, which impacted itsdetermination of its business segments for financial reporting purposes. As a result, the Company no longer reports the results of its Computer Products Groupas a separate segment. See "Note 16. Information on Business Segments" for further details on the realigned segments. The Company's three realignedsegments are as follows:Operating Segment GeographyACCO Brands North America United States and CanadaACCO Brands EMEA Europe, Middle East and AfricaACCO Brands International Australia, Latin America and Asia-PacificAs part of the realignment, the Company performed a quantitative goodwill impairment test ("Step-1") to reallocate the goodwill among the realignedsegments based on their relative fair values. There were no impairment charges recognized as a result of this change.We have restated our reportable segments for the period presented below to reflect this change.Changes in the net carrying amount of goodwill by segment were as follows: (in millions of dollars)ACCOBrandsNorth America ACCOBrandsEMEA ACCOBrandsInternational Total Balance at December 31, 2016380.7 39.5 166.9 587.1 Esselte Acquisition(5.1) 113.2 (1.6) 106.5 Translation— (23.3) — (23.3) Balance at December 31, 2017$375.6 $129.4 $165.3 $670.379ACCO Brands Corporation and SubsidiariesNotes to Consolidated Financial Statements (Continued)The goodwill balance includes $215.1 million of accumulated impairment losses, which occurred prior to December 31, 2016.Goodwill has been recorded on our Consolidated Balance Sheet related to the Esselte Acquisition and represents the excess of the cost of the EsselteAcquisition when compared to the fair value estimate of the net assets acquired on January 31, 2017 (the date of the Esselte Acquisition). See "Note 3.Acquisitions", for details on the calculation of the goodwill acquired in the Esselte Acquisition.The authoritative guidance on goodwill and other intangible assets requires that goodwill be tested for impairment at a reporting unit level. We havedetermined that our reporting units are ACCO Brands North America, ACCO Brands EMEA and ACCO Brands International. We test goodwill for impairmentat least annually and on an interim basis if an event or circumstance indicates that it is more likely than not that an impairment loss has been incurred. TheCompany performed this annual assessment, on a qualitative basis, as allowed by GAAP, in the second quarter of 2017 and concluded that no impairmentexisted.A considerable amount of management judgment and assumptions are required in performing the impairment tests, principally in determining the fairvalue of each reporting unit and the indefinite lived intangible assets. While we believe our judgments and assumptions are reasonable, different assumptionscould change the estimated fair values and, therefore, impairment charges could be required. Significant negative industry or economic trends, disruptions toour business, loss of significant customers, inability to effectively integrate acquired businesses, unexpected significant changes or planned changes in theuse of the assets or in entity structure and divestitures may adversely impact the assumptions used in the valuations and ultimately result in future impairmentcharges.Identifiable IntangiblesWe test indefinite-lived intangibles for impairment at least annually and on an interim basis if an event or circumstance indicates that it is more likelythan not that an impairment loss has been incurred. We performed this annual assessment, on a qualitative (Step-Zero) basis, as allowed by GAAP, for themajority of indefinite-lived trade names in the second quarter of 2017 and concluded that no impairment existed. For two of our indefinite-lived trade namesthat are not substantially above their carrying values, Mead® and Hilroy®, we performed quantitative tests (Step 1) in the second quarter of 2017. Thefollowing long-term growth rates and discount rates were used, 1.5% and 10.5% for Mead®, and 1.5% and 11.0% for Hilroy®, respectively. We concluded thatneither the Mead® nor Hilroy® trade names were impaired. The fair value of the Mead® trade name was less than 30% above its carrying value as of thesecond quarter of 2017 Step-1 test. As of December 31, 2017, the carrying value of the Mead® trade name was $113.3 million. As of June 1, 2017, we changed the indefinite-lived Hilroy trade name to an amortizable intangible asset. The change was made as a result of decisionsregarding the Company's future use of the trade name. The Company commenced amortizing the Hilroy trade name June 1, 2017 on a straight-line basis overa life of 30 years.The identifiable intangible assets of $277.0 million acquired in the Esselte Acquisition include amortizable customer relationships, indefinite livedand amortizable trade names and patents, which have been recorded at their estimated fair values. The fair value of the trade names and patents wasdetermined using the relief from royalty method, which is based on the present value of royalty fees derived from projected revenues. The fair value of thecustomer relationships was determined using the multi-period excess earnings method, which is based on the present value of the projected after-tax cashflows.80ACCO Brands Corporation and SubsidiariesNotes to Consolidated Financial Statements (Continued)Amortizable customer relationships, trade names and patents are expected to be amortized over lives ranging from 10 to 30 years from the EsselteAcquisition date of January 31, 2017.

RestructuringDuring 2017, the Company initiated cost savings plans related to the consolidation and integration of Esselte affecting all three of the Company'ssegments, but primarily the ACCO Brands EMEA segment. The cost savings initiatives undertaken by the Company in 2016 to further enhance its operationsin the ACCO Brands North America segment were expanded during 2017 to include the change in the operating structure in North America, includingintegration of our former Computer Products Group.During 2016, the Company initiated cost savings plans related to the consolidation and integration of the acquired Pelikan Artline business into theCompany's already existing Australia and New Zealand businesses within the ACCO Brands International segment.During the first quarter of 2018, the Company approved additional restructuring projects aggregating to $3.5 million, primarily related to changes tothe structure in the ACCO Brands North America segment and the continued integration of Esselte in the ACCO Brands EMEA segment. In accordance withGAAP, none of the aforementioned liabilities were recorded in the fourth quarter of 2017.Consistent with our previous communications about the Esselte Acquisition, the Company currently expects it will record approximately $4 million ofincremental restructuring expenses during the remainder of 2018, which is in addition to the $3.5 million of restructuring projects approved during the firstquarter of 2018. As integration plans are still being finalized, it is not possible to reasonably estimate the nature or timing of these restructuring andintegration charges or the timing of their associated cash outflows.For the years ended December 31, 2017, 2016 and 2015, we recorded restructuring charges (credits) of $21.7 million, $5.4 million and $(0.4) million,respectively.The summary of the activity in the restructuring liability (which is included in "Other current liabilities") for the year ended December 31, 2017 was asfollows:(in millions of dollars)Balance atDecember 31,2016 Esselte Acquisition(4) Provision CashExpenditures Non-cashItems/Currency Change Balance atDecember 31,2017Employee termination costs(1)$1.4 $1.5 $18.2 $(9.6) $0.5 $12.0Termination of lease agreements(2)0.1 1.2 2.4 (3.1) 0.2 0.8Other(3)— 0.1 1.1 (0.7) — 0.5Total restructuring liability$1.5 $2.8 $21.7 $(13.4) $0.7 $13.3(1) We expect the remaining $12.0 million employee termination costs to be substantially paid within the next eighteen months.(2) We expect the remaining $0.8 million termination of lease costs to be substantially paid within the next fifteen months.(3) We expect the remaining $0.5 million of other costs to be substantially paid with the next twelve months.(4) Restructuring liabilities assumed in the Esselte Acquisition.During the fourth quarter of 2017, in connection with the Pelikan Artline integration, the Company sold its building and related assets in New Zealandfor net proceeds of $3.9 million and recorded a gain on sale of $1.5 million as a reduction of SG&A expense in its Consolidated Statements of Income withinthe ACCO Brands International segment. The sale was not included in the Company’s restructuring liability activity presented above.82ACCO Brands Corporation and SubsidiariesNotes to Consolidated Financial Statements (Continued)The summary of the activity in the restructuring accounts for the year ended December 31, 2016 was as follows:(in millions of dollars)Balance atDecember 31,2015 PA Acquisition (5) Provision CashExpenditures Non-cashItems/Currency Change Balance atDecember 31,2016Employee termination costs$0.9 $— $5.2 $(4.7) $— $1.4Termination of lease agreements0.1 — 0.2 (0.2) — 0.1Total restructuring liability$1.0 $— $5.4 $(4.9) $— $1.5(5) Restructuring liabilities assumed in the PA Acquisition.The summary of the activity in the restructuring accounts for the year ended December 31, 2015 was as follows:(in millions of dollars)Balance atDecember 31,2014 Acquisitions Provision/(Credits) CashExpenditures Non-cashItems/Currency Change Balance atDecember 31,2015Employee termination costs$7.8 $— $(0.6) $(6.0) $(0.3) $0.9Termination of lease agreements0.6 — 0.2 (0.7) — 0.1Total restructuring liability$8.4 $— $(0.4) $(6.7) $(0.3) $1.0Restructuring charges (credits) for the years ended December 31, 2017, 2016 and 2015 by reporting segment were as follows: December 31,(in millions of dollars)2017 2016 2015ACCO Brands North America$5.5 $1.1 $(0.4)ACCO Brands EMEA11.2 — —ACCO Brands International5.0 4.3 — Total restructuring charges (credits)$21.7 $5.4 $(0.4)83ACCO Brands Corporation and SubsidiariesNotes to Consolidated Financial Statements (Continued)11.

The lower effective rate for 2017 of 16.7% wasprimarily driven by a $25.7 million benefit resulting from the U.S. Tax Act, and a $5.6 million benefit due to the impact of the Company's adoption of ASUNo. 2016-9, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. ASU No. 2016-9 in 2017.Tax ReformOn December 22, 2017, the U.S. Tax Act was signed into law. The U.S. Tax Act makes broad and complex changes to the U.S. tax code, including, butnot limited to: (i) reducing the future U.S. federal corporate tax rate from 35 percent to 21 percent; (ii) requiring companies to pay a one-time transition tax oncertain undistributed earnings of foreign subsidiaries; and (iii) bonus depreciation that will allow for full expensing of qualified property.The U.S. Tax Act also established new tax laws that will affect 2018, including, but not limited to: (i) the reduction of the U.S. federal corporate tax ratediscussed above; (ii) a general elimination of U.S. federal income taxes on dividends from foreign subsidiaries; (iii) a new provision designed to tax globalintangible low-taxed income ("GILTI"); (iv) the repeal of the domestic production activity deductions; (v) limitations on the deductibility of certainexecutive compensation; (vi) limitations on the use of foreign tax credits to reduce the U.S. income tax liability; and (vii) a new provision that allows adomestic corporation an immediate deduction for a portion of its foreign derived intangible income ("FDII").The SEC staff issued Staff Accounting Bulletin ("SAB") 118, which provides guidance on accounting for the tax effects of the U.S. Tax Act. SAB 118provides a measurement period that should not extend beyond one year from the enactment date84ACCO Brands Corporation and SubsidiariesNotes to Consolidated Financial Statements (Continued)for companies to complete the related accounting under ASC 740, Accounting for Income Taxes. In accordance with SAB 118, a company must reflect theincome tax effects of those aspects of the U.S. Tax Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for acertain income tax effect of the U.S. Tax Act is incomplete, but it is able to determine a reasonable estimate, it must record a provisional estimate in thefinancial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the U.S. Tax Act.Changes in tax rates and tax laws are accounted for in the period of enactment. Therefore, during the year ended December 31, 2017, we recorded a nettax benefit totaling $25.7 million related to our current provisional estimate of the provisions of the U.S. Tax Act.Transition Toll TaxThe U.S. Tax Act eliminates the deferral of U.S. income tax on the historical undistributed earnings by imposing the Transition Toll Tax, which is a one-time mandatory deemed repatriation tax on undistributed foreign earnings. The Transition Toll Tax is assessed on the U.S. shareholder's share of the foreigncorporation's accumulated foreign earnings that have not previously been taxed. Earnings in the form of cash and cash equivalents will be taxed at a rate of15.5% and all other earnings will be taxed at a rate of 8.0%.As of December 31, 2017, we have accrued income tax liabilities of $38.0 million under the Transition Toll Tax, of which $3.0 million is expected to bepaid within one year. The Transition Toll Tax will be paid over an eight-year period, starting in 2018, and will not accrue interest. The Transition Toll Taxexpense, net of foreign tax credit carryforwards of $14.0 million, is $24.0 million.Effect on Deferred Tax Assets and LiabilitiesOur deferred tax assets and liabilities are measured at the enacted tax rate expected to apply when these temporary differences are expected to berealized or settled.As our deferred tax liabilities exceed the balance of our deferred tax assets as of the date of enactment, we have recorded a tax benefit of $49.7 million,reflecting the decrease in the U.S. corporate income tax rate.Status of our AssessmentThe Company’s accounting for certain components of the U.S. Tax Act is not complete. However, the Company was able to make reasonable estimatesof the effects and recorded provisional estimates for these items. In connection with our initial analysis of the impact of the U.S. Tax Act, the Companyrecorded a provisional benefit of $25.7 million. The benefit consists of an expense of $24.0 million, net of foreign tax credit carryforwards of $14.0 million,for the one-time Transition Toll Tax and a net benefit of $49.7 million in connection with the revaluation of the deferred tax assets and liabilities resultingfrom the decrease in the U.S. corporate tax rate. To compute the Transition Toll Tax, the Company must determine the amount of post-1986 accumulatedearnings and profits of the relevant subsidiaries as well as the total non-U.S. income taxes on the earnings and profits. While the Company made a reasonableestimate of the Transition Toll Tax, further information will be gathered and analyzed in order to compute a more precise final amount. Additionally, theCompany was able to make a reasonable estimate of the impact of the reduction of the U.S. corporate tax rate, but it may be impacted by other components ofthe U.S. Tax Act, including, but not limited to, the state tax effects of adjustments to federal temporary differences, and the impact of changes to limits inconnection with the deductibility of executive compensation. Due to the complexity of the GILTI tax rules, the Company continues to analyze this provisionand its impact and the proper application of ASC 740. Under GAAP, the Company is allowed to make an accounting policy choice to either treat the taxesdue on future U.S. inclusions in taxable income related to GILTI as a current period expense when incurred (the "period cost method") or factor in suchamounts in to the Company’s measurement of deferred taxes (the "deferred method"). The Company’s selection of an accounting policy in connection withGILTI is dependent upon additional analysis and potential future modifications to the existing structure, which are yet to be known. Accordingly, theCompany has not recorded any adjustments related to GILTI in our financial statements and has not made a policy choice regarding whether to recorddeferred taxes on GILTI. The Company will continue its analysis of the impact of the U.S. Tax Act on the financial statements. The actual impact of the U.S.Tax Act may differ from the current estimate, possibly materially, due to changes to interpretations and assumptions the Company has made, future guidancethat may be issued and actions taken by the Company as a result of the law.85ACCO Brands Corporation and SubsidiariesNotes to Consolidated Financial Statements (Continued)2016 and 2015For 2016, we recorded income tax expense of $29.6 million on income before taxes of $125.1 million. The lower effective rate for 2016 of 23.7% wasdue to the following: 1) a tax benefit of $12.0 million on the previously held equity interest; due to no tax expense, under Australian tax law, on the $28.9million non-cash gain arising from the PA Acquisition due to the revaluation of the Company's ownership interest to fair value and due to the release of adeferred tax liability related to a tax basis difference in the Pelikan Artline joint-venture assets, 2) a tax benefit of $9.6 million on a net foreign exchange losson the repayment of intercompany loans, for which the pre-tax effect was recorded in equity and 3) earnings from foreign jurisdictions which are taxed at alower rate. In addition, in 2016, the Foreign Tax Credit Carryover from 2007 of $10.9 million expired, and the associated valuation allowance on thecarryover was removed; the combination of these two items does not affect income tax expense.For 2015, we recorded income tax expense of $45.5 million on income before taxes of $131.4 million. The effective rate for 2015 of 34.6%approximated the U.S. statutory tax rate of 35%.We continually review the need for establishing or releasing valuation allowances on our deferred tax assets. In 2017, the Company had a net taxbenefit from the release and generation of valuation allowances in U.S. state and certain foreign jurisdictions of $0.7 million. In 2016, the Company had a nettax benefit from the release and generation of valuation allowances in U.S. state and certain foreign jurisdictions of $0.7 million. In 2015, the Company had anet tax expense from the release and generation of valuation allowances in U.S. state and certain foreign jurisdictions of $0.3 million.As of December 31, 2017, the U.S. federal statute of limitations remains open for the year 2014 and forward. Foreign and U.S. state jurisdictions havestatutes of limitations generally ranging from 2 to 5 years. As of December 31, 2017, years still open to examination by foreign tax authorities in majorjurisdictions include Australia (2013 forward), Brazil (2011 forward), Canada (2009 forward), Germany (2011 forward), Sweden (2011 forward) and the U.K.(2016 forward). We are currently under examination in various foreign jurisdictions.Deferred tax liabilities of $83.6 million and deferred tax assets of $106.3 million acquired in the Esselte Acquisition, as of January 31, 2017, have beenrecorded at their estimated fair values. See "Note 3.

All of the undistributed earningshave become subject to U.S. income taxes due to the enactment of the U.S. Tax Act in 2017. As a result of the U.S. Tax Act, we are analyzing the globalworking capital and cash requirements, and potential tax liabilities attributable to future repatriation of cash, but we have yet to determine whether we plan tochange our prior indefinite investment assertion under ASC 740. We will record the effects of any change in prior assertions in the period in which the changeoccurs.As of December 31, 2017, $529.6 million of net operating loss carryforwards are available to reduce future taxable income of domestic andinternational companies. These loss carryforwards expire in the years 2018 through 2031 or have an unlimited carryover period.Interest and penalties related to unrecognized tax benefits are recognized within "Income tax (benefit) expense" in the Consolidated Statements ofIncome. As of December 31, 2017, we have accrued a cumulative $14.7 million for interest and penalties on the unrecognized tax benefits.A reconciliation of the beginning and ending amount of unrecognized tax benefits was as follows:(in millions of dollars)2017 2016 2015Balance at beginning of year$43.7 $34.8 $45.9Additions for tax positions of prior years2.9 3.0 3.0Reductions for tax positions of prior years(0.7) (0.5) —Esselte Acquisition1.6 — —Increase resulting from foreign currency translation— 6.4 —Decrease resulting from foreign currency translation(0.3) — (14.1)Balance at end of year$47.2 $43.7 $34.8As of December 31, 2017, the amount of unrecognized tax benefits increased to $47.2 million, of which $45.5 million would impact our effective taxrate, if recognized. We expect the amount of unrecognized tax benefits to change within the next twelve months, most notably for the Brazilian TaxAssessment (see below) for the 2011 year, which lapsed without being assessed effective January 1, 2018; and for which the Company expects to release $5.5million of the reserve in the first quarter of 2018. None of the positions included in the unrecognized tax benefit relate to tax positions for which the ultimatedeductibility is highly certain, but for which there is uncertainty about such deductibility.87ACCO Brands Corporation and SubsidiariesNotes to Consolidated Financial Statements (Continued)Income Tax AssessmentIn connection with our May 1, 2012 acquisition of the Mead Consumer and Office Products business ("Mead C&OP"), we assumed all of the taxliabilities for the acquired foreign operations including Tilibra Produtos de Papelaria Ltda. ("Tilibra"). In December of 2012, the Federal Revenue Departmentof the Ministry of Finance of Brazil ("FRD") issued a tax assessment (the "Brazilian Tax Assessment") against Tilibra, which challenged the tax deduction ofgoodwill from Tilibra's taxable income for the year 2007 (the "First Assessment"). A second assessment challenging the deduction of goodwill from Tilibra'staxable income for the years 2008, 2009 and 2010 was issued by FRD in October 2013 (the "Second Assessment"). Tilibra is disputing both of the taxassessments.Recently, the final administrative appeal of the Second Assessment was decided against the Company. We intend to challenge this decision in court inearly 2018. In connection with the judicial challenge, we may be required to post security to guarantee payment of the Second Assessment, which represents$24.6 million of the current reserve, should we not prevail. The First Assessment is still being challenged through established administrative procedures.We believe we have meritorious defenses and intend to vigorously contest these matters; however, there can be no assurances that we will ultimatelyprevail. The ultimate outcome will not be determined until the Brazilian tax appeal process is complete, which is expected to take a number of years. Inaddition, Tilibra's 2012 tax year remains open and subject to audit, and there can be no assurances that we will not receive an additional tax assessmentregarding the goodwill for 2012. The time limit for issuing an assessment for 2011 expired in January 2018 and we did not receive an assessment. The timelimit for issuing an assessment for 2012 will expire in January 2019. If the FRD's initial position is ultimately sustained, the amount assessed wouldmaterially and adversely affect our cash flow in the year of settlement.Because there is no settled legal precedent on which to base a definitive opinion as to whether we will ultimately prevail, we consider the outcome ofthis dispute to be uncertain. Since it is not more likely than not that we will prevail, in 2012, we recorded a reserve in the amount of $44.5 million (atDecember 31, 2012 exchange rates) in consideration of this contingency, of which $43.3 million was recorded as an adjustment to the purchase price andwhich included the 2007-2012 tax years plus penalties and interest through December 2012. Included in this reserve is an assumption of penalties at 75%,which is the standard penalty. While there is a possibility that a penalty of 150% could be imposed in connection with the First Assessment, based on thefacts in our case and existing precedent, we believe the likelihood of a 150% penalty is not more likely than not as of December 31, 2017. We will continueto actively monitor administrative and judicial court decisions and evaluate their impact, if any, on our legal assessment of the ultimate outcome of our case.In addition, we will continue to accrue interest related to this contingency until such time as the outcome is known or until evidence is presented that we aremore likely than not to prevail. During the years ended December 31, 2017, 2016 and 2015, we accrued additional interest as a charge to current tax expenseof $2.2 million, $2.8 million and $2.7 million, respectively. At current exchange rates, our accrual through December 31, 2017, including tax, penalties andinterest is $38.7 million.88ACCO Brands Corporation and SubsidiariesNotes to Consolidated Financial Statements (Continued)12. Earnings per ShareTotal outstanding shares as of December 31, 2017, 2016 and 2015 were 106.7 million, 107.9 million and 105.6 million respectively. Under our stockrepurchase program, for the years ended December 31, 2017 and 2015, we repurchased and retired 3.3 million and 7.7 million shares of common stock,respectively. No shares were repurchased during the year ended December 31, 2016. For each of the years ended December 31, 2017, 2016 and 2015, weacquired 0.7 million shares, related to tax withholding for share-based compensation. The calculation of basic earnings per common share is based on theweighted average number of common shares outstanding in the year, or period, over which they were outstanding. Our calculation of diluted earnings percommon share assumes that any common shares outstanding were increased by shares that would be issued upon exercise of those stock units for which theaverage market price for the period exceeds the exercise price less the shares that could have been purchased by the Company with the related proceeds,including compensation expense measured but not yet recognized.(in millions)2017 2016 2015Weighted-average number of common shares outstanding - basic108.1 107.0 108.8Stock options1.3 0.8 0.2Stock-settled stock appreciation rights— — 0.3Restricted stock units1.5 1.4 1.3Adjusted weighted-average shares and assumed conversions - diluted110.9 109.2 110.6Awards of potentially dilutive shares of common stock, which have exercise prices that were higher than the average market price during the period, arenot included in the computation of dilutive earnings per share as their effect would have been anti-dilutive. For the years ended December 31, 2017, 2016and 2015, these shares were approximately 3.1 million, 3.6 million and 5.5 million, respectively.13. Derivative Financial InstrumentsWe are exposed to various market risks, including changes in foreign currency exchange rates and interest rate changes. We enter into financialinstruments to manage and reduce the impact of these risks, not for trading or speculative purposes. The counterparties to these financial instruments aremajor financial institutions. We continually monitor our foreign currency exposures in order to maximize the overall effectiveness of our foreign currencyhedge positions. Principal currencies hedged include the U.S. dollar, Euro, Australian dollar, Canadian dollar, Swedish krona, British pound and Japaneseyen. We are subject to credit risk, which relates to the ability of counterparties to meet their contractual payment obligations or the potential non-performance by counterparties to financial instrument contracts. Management continues to monitor the status of our counterparties and will take action, asappropriate, to further manage our counterparty credit risk. There are no credit contingency features in our derivative financial instruments.When hedge accounting is applicable, on the date we enter into a derivative, the derivative is designated as a hedge of the identified exposure. Wemeasure the effectiveness of our hedging relationships both at hedge inception and on an ongoing basis.Forward Currency ContractsWe enter into forward foreign currency contracts with third parties to reduce the effect of fluctuating foreign currencies, primarily on foreigndenominated inventory purchases and intercompany loans. The majority of the Company’s exposure to local currency movements is in Europe (the Euro, theSwedish krona and the British pound), Australia, Canada, Brazil, and Mexico.Forward currency contracts are used to hedge foreign denominated inventory purchases for Europe, Australia, Canada and Japan and are designated ascash flow hedges. Unrealized gains and losses on these contracts for inventory purchases are deferred in accumulated other comprehensive income (loss)("AOCI") until the contracts are settled and the underlying hedged transactions are recognized, at which time the deferred gains or losses will be reported inthe "Cost of products sold" line in the Consolidated Statements of Income. As of December 31, 2017 and 2016, the Company had cash flow designatedforeign exchange contracts outstanding with a U.S. dollar equivalent notional value of $93.5 million and $76.5 million, respectively.Forward currency contracts used to hedge foreign denominated intercompany loans are not designated as hedging instruments.

Fair Value of Financial InstrumentsIn establishing a fair value, there is a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The basis of thefair value measurement is categorized in three levels, in order of priority, as described below:Level 1Unadjusted quoted prices in active markets for identical assets or liabilitiesLevel 2Unadjusted quoted prices in active markets for similar assets or liabilities, or Unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or Inputs other than quoted prices that are observable for the asset or liabilityLevel 3Unobservable inputs for the asset or liability90ACCO Brands Corporation and SubsidiariesNotes to Consolidated Financial Statements (Continued)We utilize the best available information in measuring fair value. Financial assets and liabilities are classified in their entirety based on the lowest levelof input that is significant to the fair value measurement.We have determined that our financial assets and liabilities described in "Note 13. Derivative Financial Instruments" are Level 2 in the fair valuehierarchy. The following table sets forth our financial assets and liabilities that were accounted for at fair value on a recurring basis as of December 31, 2017and 2016:(in millions of dollars)December 31, 2017 December 31, 2016Assets: Forward currency contracts$25.1 $4.4Liabilities: Forward currency contracts25.4 0.3Our forward currency contracts are included in "Other current assets," "Other non-current assets," "Other current liabilities," or "Other non-currentliabilities" and do not extend beyond December 2018, except for one which extends to December 2020. The forward foreign currency exchange contracts areprimarily valued based on the foreign currency spot and forward rates quoted by the banks or foreign currency dealers. As such, these derivative instrumentsare classified within Level 2.The fair values of cash and cash equivalents, notes payable to banks, accounts receivable and accounts payable approximate carrying amounts dueprincipally to their short maturities. The carrying amount of total debt was $939.5 million and $703.5 million and the estimated fair value of total debt was$951.5 million and $708.4 million as of December 31, 2017 and 2016, respectively. The fair values are determined from quoted market prices, whereavailable, and from investment bankers using current interest rates considering credit ratings and the remaining terms of maturity.15.

Information on Business SegmentsEffective in the first quarter of 2017, as a result of the Esselte Acquisition, the Company realigned its operating structure, which affected the makeup ofits business segments for financial reporting purposes. The Company has three operating business segments each of which is comprised of differentgeographic regions. The Company no longer reports the results of its Computer Products Group as a separate segment. Results of the former ComputerProducts Group are reflected in the appropriate geographic segment based on the region from which sales are made. The Company's three realigned businesssegments are as follows:Operating Segment Geographic Regions Primary BrandsACCO Brands North America United States and Canada AT-A-GLANCE®, Five Star®, GBC®, Hilroy®, Kensington®,Mead®, Quartet®, and Swingline® ACCO Brands EMEA Europe, Middle East and Africa Derwent®, Esselte®, GBC®, Kensington®, Leitz®, NOBO®,Rapid®, and Rexel® ACCO Brands International Australia, Latin America and Asia-Pacific Artline®, GBC®, Kensington®, Marbig®, Quartet®, Rexel®,Tilibra®, and Wilson Jones®We have restated our financial statements for each of the periods presented to reflect this change in reportable business segments.Each of the Company's three operating segments designs, markets, sources, manufactures and sells recognized consumer and end-user demanded brandsused in businesses, schools and homes.

Joint-Venture InvestmentSummarized below is the financial information for the Pelikan Artline joint-venture, in which we owned a 50% non-controlling interest, through May1, 2016, which was accounted for using the equity method.

Commitments and ContingenciesPending LitigationIn connection with our May 1, 2012 acquisition of the Mead C&OP business, we assumed all of the tax liabilities for the acquired foreign operationsincluding Tilibra Produtos de Papelaria Ltda. ("Tilibra"). For further information see "Note 11. Income Taxes - Income Tax Assessment" for details on taxassessments issued by the FRD against Tilibra, which challenged the tax deduction of goodwill from Tilibra's taxable income for the years 2007 through2010.We are party to various lawsuits and regulatory proceedings, primarily related to alleged patent infringement and employee terminations as well asother claims incidental to our business. In addition, we may be unaware of third party claims of intellectual property infringement relating to our technology,brands or products and we may face other claims related to business operations. Any litigation regarding patents or other intellectual property could be costlyand time-consuming and might require us to pay monetary damages or enter into costly license agreements. We also may be subject to injunctions againstdevelopment and sale of certain of our products.It is the opinion of management that (other than the Brazilian Tax Assessment) the ultimate resolution of currently outstanding matters will not have amaterial adverse effect on our financial condition, results of operations or cash flow. However, there is no assurance that we will ultimately be successful inour defense of any of these matters or that an adverse outcome in any matter will not affect our results of operations, financial condition or cash flow. Further,future claims, lawsuits and legal proceedings could materially and adversely affect our business, reputation, results of operations and financial condition.Lease CommitmentsFuture minimum rental payments for all non-cancelable operating leases (reduced by minor amounts from subleases) as of December 31, 2017 were asfollows:(in millions of dollars) 2018$28.1201925.0202021.6202116.2202212.2Thereafter17.6Total minimum rental payments120.7Less minimum rentals to be received under non-cancelable subleases2.0Future minimum payments for operating leases, net of sublease rental income$118.7Total rental expense reported in our Consolidated Statements of Income for all non-cancelable operating leases (reduced by minor amounts forsubleases) amounted to $30.9 million, $24.2 million and $21.2 million for the years ended December 31, 2017, 2016 and 2015, respectively.97ACCO Brands Corporation and SubsidiariesNotes to Consolidated Financial Statements (Continued)Unconditional Purchase CommitmentsFuture minimum payments under unconditional purchase commitments, primarily for inventory purchase commitments as of December 31, 2017 wereas follows:(in millions of dollars) 2018$96.820190.220200.12021—2022—Thereafter—Total unconditional purchase commitments$97.1EnvironmentalWe are subject to national, state, provincial and/or local environmental laws and regulations concerning the discharge of materials into theenvironment and the handling, disposal and clean-up of waste materials and otherwise relating to the protection of the environment. This includesenvironmental laws and regulations that affect the design and composition of certain of our products. It is not possible to quantify with certainty the potentialimpact of actions regarding environmental matters, particularly remediation and other compliance efforts that we may undertake in the future. In the opinionof management, compliance with the present environmental protection laws, before taking into account estimated recoveries from third parties, will not havea material adverse effect upon our capital expenditures, financial condition and results of operations or competitive position.98ACCO Brands Corporation and SubsidiariesNotes to Consolidated Financial Statements (Continued)19.

Two principal factors contribute to this seasonality: (1) we are a major supplier of products related to the back-to-school season, whichoccurs principally from June through September for our North American business and from November through February for our Australian andBrazilian businesses; and (2) several product categories we sell lend themselves to calendar year-end purchase timing, including planners, paperorganization and storage products (including bindery) and Kensington® computer accessories, which have higher sales in the fourth quarter driven bytraditionally strong fourth-quarter sales of personal computers and tablets.(2)The sum of the quarterly earnings per share amounts may not equal the total for the year due to the effects of rounding, dilution as a result of issuingshares of common stock and repurchasing of shares of common stock during the year.99ACCO Brands Corporation and SubsidiariesNotes to Consolidated Financial Statements (Continued)20.
