Acquisitions	'
	Acquisitions
	On May 1, 2012, the Company completed the Merger of Mead C&OP with a wholly-owned subsidiary of the Company. Mead C&OP was a leading manufacturer and marketer of school supplies, office products, and planning and organizing tools - including the Mead®, Five Star®, Trapper Keeper®, AT-A-GLANCE®, Cambridge®, Day Runner®, Hilroy, Tilibra and Grafons brands in the U.S., Canada and Brazil.
	In the Merger, MWV shareholders received 57.1 million shares of the Company's common stock, or 50.5% of the combined company, valued at $602.3 million on the date of the Merger. After the transaction was completed the Company had 113.1 million common shares outstanding.
	The purchase price, net of working capital adjustments and cash acquired, was $999.8 million. The consideration given included 57.1 million shares of ACCO Brands common stock, which were issued to MWV shareholders with a fair value of $602.3 million and a $460.0 million dividend paid to MWV. The calculation of consideration given for Mead C&OP was finalized during the fourth quarter of 2012 and is described in the following table:
	(in millions, except per share price)	At May 1, 2012
	Calculated consideration for Mead C&OP:
	Outstanding shares of ACCO Brands common stock (1)	56
	Multiplier needed to calculate shares to be issued (2)	1.02020202
	Number of shares issued to MWV shareholders	57.1
	Closing price per share of ACCO Brands common stock (3)	$	10.55
	Value of common shares issued	$	602.3
	Plus:
	Dividend paid to MWV	460
	Less:
	Working capital adjustment (4)	(30.5		)
	Consideration for Mead C&OP	$	1,031.80
	(1) Represents the number of shares of the Company's common stock as of May 1, 2012.
	(2) Represents MWV shareholders' negotiated ownership percentage in ACCO Brands of 50.5% divided by the 49.5% that was owned by ACCO Brands shareholders upon completion of the Merger.
	(3) Represents the closing price per share of the Company's stock as of April 30, 2012.
	(4) Represents the difference between the target net working capital and the closing net working capital as of April 30, 2012.
	The following table presents the allocation of the purchase price to the fair values of the assets acquired and liabilities assumed at the date of acquisition:
	(in millions of dollars)	At May 1, 2012
	Calculation of Goodwill:
	Consideration given for Mead C&OP	$	1,031.80
	Cash acquired	(32.0		)
	Net purchase price	$	999.8
	Plus fair value of liabilities assumed:
	Accounts payable and accrued liabilities	103.9
	Current and non-current deferred tax liabilities	209.6
	Other non-current liabilities	72.9
	Fair value of liabilities assumed	$	386.4
	Less fair value of assets acquired:
	Accounts receivable	73.3
	Inventory	143.5
	Property, plant and equipment	136.6
	Identifiable intangibles	543.2
	Other assets	24.3
	Fair value of assets acquired	$	920.9
	Goodwill	$	465.3
	In the first quarter of 2013 we finalized our fair value estimate of assets acquired and liabilities assumed as of the acquisition date. The final excess of the purchase price over the fair value of net assets acquired has been allocated to goodwill in the amount of $465.3 million. As the allowable one-year evaluation period since the date of acquisition has expired, no additional adjustments to the goodwill related to the acquisition of Mead C&OP will be recognized.
	Cumulative acquisition-related costs of $20.1 million were incurred during the years 2011 and 2012 and were classified as Selling, General and Administrative expenses. Acquisition-related costs of $1.3 million and $14.4 million were incurred during the three and nine months ended September 30, 2012.

	Basis of Presentation
	As used in this Quarterly Report on Form 10-Q for the quarter ended September 30, 2013, the terms "ACCO Brands," "ACCO," the "Company," "we," "us," and "our" refer to ACCO Brands Corporation and its consolidated domestic and international subsidiaries.
	The management of ACCO Brands is responsible for the accuracy and internal consistency of the condensed consolidated financial statements and notes contained in this Quarterly Report on Form 10-Q.
	The condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Although the Company believes the disclosures are adequate to make the information presented not misleading, certain information and note disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the U.S. have been condensed or omitted pursuant to those rules and regulations. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2012.
	The Condensed Consolidated Balance Sheet as of September 30, 2013, the related Condensed Consolidated Statements of Operations and the Consolidated Statements of Comprehensive Income (Loss) for the three and nine months ended September 30, 2013 and 2012 and Condensed Consolidated Statements of Cash Flows for the nine months ended September 30, 2013 and 2012 are unaudited. The December 31, 2012 Condensed Consolidated Balance Sheet data was derived from audited financial statements, but does not include all annual disclosures required by accounting principles generally accepted in the U.S. The above referenced financial statements included herein were prepared by management on the same basis as the Company's audited consolidated financial statements for the year ended December 31, 2012 and reflect all adjustments (consisting solely of normal recurring items unless otherwise noted) which are, in the opinion of management, necessary for the fair presentation of results of operations and cash flows for the interim periods ended September 30, 2013 and 2012, and the financial position of the Company as of September 30, 2013. Interim results may not be indicative of results for a full year.
	On May 1, 2012, the Company completed the merger of the Consumer and Office Products Business of MeadWestvaco Corporation ("MWV") (“Mead C&OP”) with a wholly-owned subsidiary of the Company (the "Merger"). Accordingly, the results of Mead C&OP are included in the Company's condensed consolidated financial statements from the date of the Merger.
	As part of the inclusion of Mead C&OP financial results with those of the Company, in the second quarter of 2012, certain information technology costs associated with the manufacturing, procurement and distribution operations have been reclassified from advertising, selling, general and administrative expenses (SG&A) to cost of products sold. This reclassification was done to enable the financial results of the two businesses to be consistent and to better reflect those costs associated with the cost of products sold. All prior periods have been reclassified to make the results comparable. For the nine months ended September 30, 2012 reclassified costs totaled $4.0 million. These historical reclassifications were not material and have had no effect on net income.
	The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make certain estimates and assumptions that affect the reported assets and liabilities at the date of the financial statements and the reported revenues and expenses during the reporting periods. Actual results could differ from those estimates.

	Effective May 13, 2013 (the “Effective Date”), the Company entered into an Amended and Restated Credit Agreement (the “Restated Credit Agreement”) among the Company, certain subsidiaries of the Company, Bank of America, N.A., as administrative agent, and the other agents and lenders party thereto. The Restated Credit Agreement amended and restated the Company's existing credit agreement, dated as of March 26, 2012, as amended (the “2012 Credit Agreement”), that had been entered into in connection with the Company's acquisition of Mead C&OP. In addition, immediately prior to the effectiveness of the Restated Credit Agreement, the Company entered into a Second Amendment, dated as of May 13, 2013 (the “Second Amendment ”), to the 2012 Credit Agreement in order to facilitate the entry into and obtain certain lender consents for the Restated Credit Agreement.
	The Restated Credit Agreement provides for a $780 million, five-year senior secured credit facility, which consists of a $250.0 million multi-currency revolving credit facility, due May 2018 (the “Revolving Facility”) and a $530.0 million U.S. dollar denominated Senior Secured Term Loan A, due May 2018 (the “Restated Term Loan A"). Specifically, in connection with the Restated Credit Agreement, the Company:
	•	replaced the Company's then-existing U.S.-dollar denominated Senior Secured Term Loan A, due May 2017, under the 2012 Credit Agreement, which had an aggregate principal amount of $220.8 million outstanding immediately prior to the Effective Date, with the Restated Term Loan A, due May 2018, in an aggregate original principal amount of $530.0 million;
	•	prepaid in full the Company's then-existing U.S.-dollar denominated Senior Secured Term Loan B, due May 2019, under the 2012 Credit Agreement, which had an aggregate principal amount of $310.2 million outstanding immediately prior to the Effective Date, using a portion of the proceeds from the Restated Term A Loan;
	•	replaced the $250.0 million revolving credit facility under the 2012 Credit Agreement with the Revolving Facility, under which $47.3 million was outstanding immediately following the Effective Date; and
	•	prior to the Effective Date, the Company's Canadian-dollar denominated Senior Secured Term Loan A, due May 2017 that had been drawn under the 2012 Credit Agreement was fully repaid.
	As of September 30, 2013, there were borrowings of $1.7 million under our $250.0 million Revolving Facility. The amount available for borrowings was $237.8 million (allowing for $10.5 million of letters of credit outstanding on that date).
	For the nine months ended September 30, 2013, included in Other expense, net is a $9.4 million charge for the write-off of debt origination costs associated with the refinancing. Additionally, the Company incurred approximately $4.5 million in bank, legal and other fees associated with the Restated Credit Agreement. Of these fees, $4.2 million were capitalized and will be amortized over the life of the Restated Term Loan A and the Revolving Facility.
	Loan Covenants
	As of and for the period ended September 30, 2013, the Company was in compliance with all applicable loan covenants.
	Guarantees and Security
	Generally, obligations under the Restated Credit Agreement are guaranteed by certain of the Company's existing and future domestic subsidiaries, and are secured by substantially all of the Company's and certain guarantor subsidiaries' assets, subject to certain exclusions and limitations.

	As more fully described in the Company’s 2012 Annual Report on Form 10-K, we test goodwill for impairment at 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. The Company performed this annual assessment in the second quarter of 2013 and concluded that no impairment exists.
	Goodwill has been recorded on the Company's balance sheet related to the Merger and represents the excess of the cost of the acquisition when compared to the fair value estimate of the net assets acquired on May 1, 2012 (the date of the Merger). See Note 3, Acquisitions, to these condensed consolidated financial statements for details on the calculation of the goodwill acquired in the Merger.
	Changes in the net carrying amount of goodwill by segment are as follows:

	Identifiable Intangible Assets
	The gross carrying value and accumulated amortization by class of identifiable intangible assets as of September 30, 2013 and December 31, 2012 are as follows:

	-1	Accumulated amortization prior to the adoption of authoritative guidance on goodwill and other intangible assets, at which time further amortization ceased.
	The Company’s intangible amortization expense was $5.9 million and $6.9 million for the three months ended September 30, 2013 and 2012, respectively, and $18.7 million and $13.5 million for the nine months ended September 30, 2013 and 2012, respectively. The increase in the nine month period of intangible amortization expense was driven by incremental amortization related to the Merger.
	As of September 30, 2013, estimated amortization expense for amortizable intangible assets as of September 30, 2013 for the current year and the next five years are as follows:
	(in millions of dollars)	2013			2014				2015		2016			2017				2018
	Estimated amortization expense	$	24.8		$	22.3			$	19.9	$	17.6		$	14.3			$	12.1
	Actual amounts of amortization expense may differ from estimated amounts due to changes in foreign currency exchange rates, additional intangible asset acquisitions, impairment of intangible assets, accelerated amortization of intangible assets and other events.
	The identifiable intangible assets of $543.2 million acquired in the Merger include trade names and customer relationships and were recorded at their fair values. The values assigned were based on the estimated future discounted cash flows attributable to the respective assets. These future cash flows were estimated based on the historical cash flows and then adjusted for anticipated future changes, primarily expected changes in sales volume or price. We have assigned an indefinite life to certain trade names, which include the Five Star®, Mead®, Tilibra and Hilroy brands, based on the Company's intention to use these trade names for an indefinite period of time and the expected sustainability of brands and the product categories and cash flows with which they are associated. Each of the named brands has a long history of high brand recognition in the markets that it serves, has significant market share in the product categories in which it competes and has demonstrated strong historical financial performance.
	We test indefinite-lived intangibles for impairment at 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. The Company performed this annual assessment in the second quarter of 2013 and concluded that no impairment exists. However, due to the recent acquisition of Mead C&OP, the fair values of certain indefinite-lived trade names are not substantially above their carrying values.

Restructuring and Related Activities [Abstract]	'
Restructuring	'
	Restructuring
	During the nine months ended September 30, 2013, the Company committed to new cost savings plans intended to improve the efficiency and effectiveness of our businesses. These plans relate to cost-reduction initiatives within the Company's North American and International segments, and are primarily associated with post-merger integration activities of the North American operations following the acquisition of Mead C&OP and changes in the European business model and manufacturing footprint. The most significant of these plans was finalized during the second quarter of 2013, and relates to the closure of our Brampton, Canada distribution and manufacturing facility and relocation of its activities to other facilities within the Company. The Company recorded $2.3 million and $0.8 million of restructuring charges for the three months ended September 30, 2013 and 2012, respectively, and $17.9 million and $21.6 million of restructuring charges for the nine months ended September 30, 2013 and 2012, respectively. The Company expects approximately $7 million of additional restructuring charges to be incurred in 2013 associated primarily with other initiatives which are currently under development.
	In fiscal year 2012, we initiated cost savings plans related to the consolidation and integration of our recently acquired Mead C&OP business. The most significant of these plans related to our dated goods business and included closure of a manufacturing and distribution facility in East Texas, Pennsylvania and relocation of its activities to other facilities within the Company, which was completed during the second quarter of 2013. We also committed to certain cost savings plans that are expected to improve the efficiency and effectiveness of our U.S. and European businesses, which were independent of any plans related to our acquisition of Mead C&OP.
	A summary of the activity in the restructuring accounts for the nine months ended September 30, 2013 is as follows:
	(in millions of dollars)	Balance at December 31, 2012		Provision		Cash			Non-cash			Balance at September 30, 2013

	Management expects the $15.2 million of employee termination costs to be substantially paid within the next 12 months.
	Gain on Sale
	Not included in the restructuring table above is a net gain of $2.5 million from the sale of the Company's Ireland distribution facility. The sale, which occurred during the second quarter of 2013, generated net cash proceeds of $3.8 million. The gain on sale has been recognized in our Consolidated Statements of Operations in selling, general and administrative expenses.

Income Taxes	'
	Income Taxes
	For the three months ended September 30, 2013, the Company recorded an income tax expense from continuing operations of $14.6 million on income before taxes of $41.0 million. For the prior-year period, we reported an income tax benefit from continuing operations of $13.6 million on income before taxes of $41.6 million. The low tax rate for 2012 was primarily due to a change in the effective tax rate for foreign earnings resulting in a cumulative period adjustment during the third quarter of 2012 and the release of certain valuation allowances, as further discussed below.
	We continually review the need for establishing or releasing valuation allowances on our deferred tax attributes. Following the acquisition of Mead C&OP, in the second quarter of 2012, the Company analyzed its need for maintaining valuation reserves against the expected U.S. future tax benefits. Based on that analysis, the Company determined that as of June 30, 2012, there existed sufficient evidence in the form of future taxable income from the combined operations to release $112.7 million of the valuation allowance that had been previously recorded against the U.S. deferred income tax assets. Also in the second quarter of 2012 valuation allowances in the amount of $17.7 million were released in certain foreign jurisdictions and an additional $0.5 million was released in the third quarter 2012, for a total release of foreign valuation allowances of $18.2 million. The 2013 year-to-date period benefited from the release of foreign valuation allowances in certain foreign jurisdictions in the amount of $7.0 million. The resulting deferred tax assets are comprised principally of net operating loss carryforwards that are expected to be fully realized within the expiration period and other temporary differences.
	For the nine months ended September 30, 2013, the Company recorded an income tax expense from continuing operations of $6.6 million on income before taxes of $33.6 million, which included the valuation release discussed above. For the prior-year period, we reported an income tax benefit from continuing operations of $185.2 million on a loss before taxes of $53.1 million, primarily due to the release of certain valuation allowances, also as discussed above.
	The reconciliation of income taxes for the three and nine month periods ended September 30, 2013 and 2012, computed at the U.S. federal statutory income tax rate, compared to our effective income tax rate for continuing operations, is as follows:
		Three Months Ended September 30,						Nine Months Ended September 30,
	(in millions of dollars)	2013			2012			2013			2012

	Effective tax rate	35.6		%	NM			19.6		%	NM
	The U.S. federal statute of limitations remains open for the year 2010 and forward. Foreign and U.S. state jurisdictions have statutes of limitations generally ranging from 3 to 5 years. Years still open to examination by foreign tax authorities in major jurisdictions include Australia (2008 forward), Brazil (2007 forward), Canada (2006 forward) and the U.K. (2010 forward). We are currently under examination in various foreign jurisdictions.
	In connection with our May 1, 2012 acquisition of Mead C&OP we assumed all of the tax liabilities for the acquired foreign operations. In December of 2012, the Federal Revenue Department of the Ministry of Finance of Brazil ("FRD") issued a tax assessment for the 2007 tax year against Tilibra Produtos de Papelaria Ltda. ("Tilibra"), which challenged the deductibility of goodwill recorded in connection with Mead's 2004 acquisition of Tilibra. In the fourth quarter of 2012, the Company recorded a reserve in the amount of $44.5 million (based on December 2012 exchange rates) in consideration of the 2007 assessment and the expected assessment to be received for the open tax years. In October 2013, the Company received the assessment from FRD for the 2008-2010 tax years. The Company has filed a protest disputing the assessment for the 2007 tax year and it intends to likewise challenge the new assessment. The assessment was as expected, and already reserved for in the 2012 financial statements. In addition, the Company will continue to accrue interest related to this matter until such time as the outcome is known or until evidence is presented that we are more likely than not to prevail. During the three and nine month periods ended September 30, 2013, we accrued additional interest of $0.3 million and $1.0 million, respectively, which was recorded in income tax expense.

	Earnings per Share
	Total outstanding shares as of September 30, 2013 and 2012 were 113.6 million and 113.1 million, respectively. On May 1, 2012 the Company issued 57.1 million shares of stock related to the Merger. The calculation of basic earnings per common share is based on the weighted average number of common shares outstanding in the year, or period, over which they were outstanding. Our calculation of diluted earnings per common share assumes that any common shares outstanding were increased by shares that would be issued upon exercise of those stock units for which the average 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, net of tax.

	Awards of potentially dilutive shares of common stock options which have exercise prices that were higher than the average market price during the period are not included in the computation of dilutive earnings per share as their effect would have been anti-dilutive. These shares totaled approximately 6.1 million and 7.0 million as of September 30, 2013 and 2012, respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]	'
Derivative Financial Instruments	'
	Derivative Financial Instruments
	We are exposed to various market risks, including changes in foreign currency exchange rates and interest rate changes. We enter into financial instruments to manage and reduce the impact of these risks, not for trading or speculative purposes. The counterparties to these financial instruments are major financial institutions. We continually monitor our foreign currency exposures in order to maximize the overall effectiveness of our foreign currency hedge positions. Principal currencies hedged include the U.S. dollar, Euro, Australian dollar, Canadian dollar, Pound sterling and Japanese yen. 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, as appropriate, to further manage our counterparty credit risk. There are no credit contingency features in our derivative financial instruments.
	On the date in which we enter into a derivative, the derivative is designated as a hedge of the identified exposure. We measure the effectiveness of our hedging relationships both at hedge inception and on an ongoing basis.
	Forward Currency Contracts
	We enter into forward foreign currency contracts to reduce the effect of fluctuating foreign currencies, primarily on foreign denominated inventory purchases and intercompany loans. The majority of the Company’s exposure to local currency movements is in Europe, Australia, Canada, Brazil, Mexico and Japan.
	Forward currency contracts are used to hedge foreign denominated inventory purchases for Europe, Australia, Canada and Japan and are designated as cash flow hedges. Unrealized gains and losses on these contracts for inventory purchases are deferred in other comprehensive income (loss) until the contracts are settled and the underlying hedged transactions are recognized, at which time the deferred gains or losses will be reported in the “Cost of products sold” line in the Condensed Consolidated Statements of Operations. As of September 30, 2013 and December 31, 2012, we had cash-flow-designated foreign exchange contracts outstanding with a U.S. dollar equivalent notional value of $95.7 million and $85.0 million, respectively.
	Forward currency contracts used to hedge foreign denominated intercompany loans are not designated as hedging instruments. Gains and losses on these derivative instruments are recognized within "Other expense, net" in the Condensed Consolidated Statements of Operations and are largely offset by the changes in the fair value of the hedged item. The periods of the forward foreign exchange contracts correspond to the periods of the hedged transactions, and do not extend beyond September 2014. As of September 30, 2013 and December 31, 2012, we had undesignated foreign exchange contracts outstanding with a U.S. dollar equivalent notional value of $47.9 million and $90.4 million, respectively.

Fair Value Disclosures [Abstract]	'
Fair Value Of Financial Instruments	'
	Fair Value of Financial Instruments
	In 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 the fair value measurement is categorized in three levels, in order of priority, as described below:
	Level 1	Unadjusted quoted prices in active markets for identical assets or liabilities
	Level 2	Unadjusted 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 liability
	Level 3	Unobservable inputs for the asset or liability
	We utilize the best available information in measuring fair value. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.
	We have determined that our financial assets and liabilities are Level 2 in the fair value hierarchy. The following table sets forth our financial assets and liabilities that were accounted for at fair value on a recurring basis as of September 30, 2013 and December 31, 2012, respectively:
	(in millions of dollars)	September 30,		December 31,
		2013		2012
	Assets:
	Forward currency contracts	$	1.3	$	1.2
	Liabilities:
	Forward currency contracts	$	1.6	$	0.8
	Our forward currency contracts are included in "Other current assets" or "Other current liabilities" and mature within 12 months. The forward foreign currency exchange contracts are primarily valued based on the foreign currency spot and forward rates quoted by the banks or foreign currency dealers. As such, these derivative instruments are classified within Level 2.
	The fair values of cash and cash equivalents, notes payable to banks, accounts receivable and accounts payable approximate carrying amounts due principally to their short maturities. The carrying amount of total debt was $1,000.7 million and $1,072.1 million and the estimated fair value of total debt was $997.0 million and $1,097.5 million at September 30, 2013 and December 31, 2012, respectively. The fair values are determined from quoted market prices, where available, and from investment bankers using current interest rates considering credit ratings and the remaining terms of maturity.

	Information on Business Segments
	In conjunction with the Merger during the second quarter of 2012, we realigned our Americas and International segments. The pre-acquisition Latin America business has been moved into the International segment along with Mead C&OP's Brazilian operations. Our Computer Products Group was unaffected by the realignment or the Merger.
	The Company’s three business segments are described below.
	ACCO Brands North America and ACCO Brands International
	Our office, school and calendar product lines use name brands such as: AT-A-GLANCE®, Day-Timer®, Five Star®, GBC®, Hilroy®, Marbig, Mead®, NOBO, Quartet®, Rexel, Swingline®, Tilibra, Wilson Jones® and many others. Products and brands are not confined to one channel or product category and are sold based on end-user preference in each geographic location. We manufacture approximately 50% of our products, and specify and source approximately 50% of our products, mainly from Asia. The majority of our office products, such as stapling, binding and laminating equipment and related consumable supplies, shredders and whiteboards, are used by businesses. Most of these end-users purchase their products from our customers, which include commercial contract stationers, mass merchandisers, retail superstores, wholesalers, resellers, mail order and internet catalogs, club stores and dealers. We also supply some of our products directly to large commercial and industrial end-users. For all of our products, historically, we have targeted the premium end of the product categories in which we compete. However, we also supply private label products for our customers and provide machine maintenance and certain repair services. Our school products include notebooks, folders, decorative calendars, and stationery products. We distribute our school products primarily through traditional and online retail mass market, grocery, drug and office superstore channels. Our calendar products are sold throughout all channels where we sell office or school products, and we also sell calendar products direct to consumers.
	The customer base to which we sell our products is mainly made up of large global and regional resellers of our products. Mass and retail channels mainly sell to individual consumers but also to small businesses. Office superstores mainly sell to commercial customers but also to individual consumers at their retail stores. As a result, there is no clear correlation between product, consumer or distribution channel. We also sell to commercial contract stationers, wholesalers, distributors, mail order and internet catalogs, and independent dealers. Over half of our product sales by our customers are to business end-users, who generally seek premium products that have added value or ease-of-use features and a reputation for reliability, performance and professional appearance. Some of our document finishing products are sold directly to high-volume end-users and commercial reprographic centers.
	Computer Products Group
	The Computer Products Group designs, distributes, markets and sells accessories for laptop and desktop computers and tablets and smart phones. These accessories primarily include security products,tablet covers and keypads, smart phone accessories, power adapters, input devices such as mice, laptop computer carrying cases, hubs, docking stations and ergonomic devices. The Computer Products Group sells mostly under the Kensington®, Microsaver® and ClickSafe® brand names, with the majority of its revenue coming from the U.S. and Western Europe.
	Our computer products are manufactured by third-party suppliers, principally in Asia, and are stored in and distributed from our regional facilities. Our computer products are sold primarily to consumer electronics retailers, information technology value-added resellers, original equipment manufacturers and office products retailers.

	Pending Litigation - Brazil Tax Assessment
	In connection with our May 1, 2012 acquisition of Mead C&OP we assumed all of the tax liabilities for the acquired foreign operations. In December of 2012, the Federal Revenue Department of the Ministry of Finance of Brazil ("FRD") issued a tax assessment for the 2007 tax year against Tilibra Produtos de Papelaria Ltda. ("Tilibra"), which challenged the deductibility of goodwill recorded in connection with Mead's 2004 acquisition of Tilibra. In the fourth quarter of 2012, the Company recorded a reserve in the amount of $44.5 million (based on December 2012 exchange rates) in consideration of the 2007 assessment and the expected assessment to be received for the open tax years. In October 2013, the Company received the assessment from FRD for the 2008-2010 tax years. The Company has filed a protest disputing the assessment for the 2007 tax year and it intends to likewise challenge the new assessment. The assessment was as expected, and already reserved for in the 2012 financial statements. In addition, the Company will continue to accrue interest related to this matter until such time as the outcome is known or until evidence is presented that we are more likely than not to prevail. During the three and nine months ended September 30, 2013 we accrued additional interest of $0.3 million and $1.0 million, respectively.
	Other Pending Litigation
	There are various other claims, lawsuits and pending actions against us incidental to our operations. It is the opinion of management that the ultimate resolution of these matters will not have a material adverse effect on our consolidated financial position, results of operations or cash flows. However, we can make no assurances that we will ultimately be successful in our defense of any of these matters.
	Environmental
	We are subject to laws and regulations relating to the protection of the environment. While it is not possible to quantify with certainty the potential impact of actions regarding environmental matters, particularly remediation and other compliance efforts that our subsidiaries may undertake in the future, in the opinion of management, compliance with the present environmental protection laws, before taking into account any estimated recoveries from third parties, will not have a material adverse effect upon the results of operations, cash flows or financial condition of the Company.

	19. Condensed Consolidating Financial Information
	Certain of the Company’s 100% owned domestic subsidiaries are required to jointly and severally, fully and unconditionally guarantee the 6.75% Senior Unsecured Notes that are due in the year 2020. Rather than filing separate financial statements for each guarantor subsidiary with the Securities and Exchange Commission, the Company has elected to present the following condensed consolidating financial statements, which detail the results of operations for the three and nine months ended September 30, 2013 and 2012, cash flows for the nine months ended September 30, 2013, and 2012, and financial position as of September 30, 2013 and December 31, 2012 of the Company and its guarantor and non-guarantor subsidiaries (in each case carrying investments under the equity method), and the eliminations necessary to arrive at the reported amounts included in the condensed consolidated financial statements of the Company. Certain previously reported amounts within the December 2012 condensed consolidating balance sheet have been revised to appropriately reflect the allocation of $70.9 million of goodwill and receivables from affiliates within the Guarantor balance sheet. The revisions resulted in these line items in the condensed consolidating balance sheet moving between the guarantor and non-guarantor columns of the accompanying balance sheet presentation. Such revisions were immaterial to the previously reported guarantors’ condensed consolidating balance sheet.
