As a result, reported diluted earnings per share for the three months ended MarchB 31, 2015 and 2014 are the same as basic earnings per share.

	As used in this Quarterly Report on Form 10-Q for the quarter ended March 31, 2015, the terms "ACCO Brands," "ACCO," the "Company," "we," "us," and "our" refer to ACCO Brands Corporation and its consolidated 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 SEC. 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. ("U.S. GAAP") 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, 2014.
	The Condensed Consolidated Balance Sheet as of March 31, 2015, the related Condensed Consolidated Statements of Operations and the Consolidated Statements of Comprehensive Income (Loss) for the three months ended March 31, 2015 and 2014 and Condensed Consolidated Statements of Cash Flows for the three months ended March 31, 2015 and 2014 are unaudited. The December 31, 2014 Condensed Consolidated Balance Sheet data was derived from audited financial statements, but does not include all annual disclosures required by U.S. GAAP. 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, 2014 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 March 31, 2015 and 2014, and the financial position of the Company as of March 31, 2015. Interim results may not be indicative of results for a full year.
	We reclassified certain costs from cost of products sold to SG&A to align classifications of certain expenses across our businesses. All prior periods have been adjusted to make the results comparable. For the three months ended March 31, 2014, reclassified costs totaled $0.2 million. These historical reclassifications were not material and have had no effect on net income.
	The preparation of financial statements in conformity with U.S. GAAP 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.

	The Company’s intangible amortization expense was $5.2 million and $5.9 million for the three months ended March 31, 2015 and 2014, respectively.
	Estimated amortization expense for amortizable intangible assets as of March 31, 2015 for the current year and the next five years are as follows:

	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.
	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 2014 and concluded that no impairment existed.

Restructuring	Restructuring
	During 2014, we initiated restructuring actions that further enhance our ongoing efforts to centralize, control and streamline our global and regional operational, supply chain and administrative functions, primarily associated with our North American school, office and Computer Products Group workforce.
	We recorded $0.5 million of income and $1.1 million of expense related to these restructuring actions for the three months ended March 31, 2015 and 2014, respectively. Employee termination income in 2015 relates to the release of reserves no longer required.
	A summary of the activity in the restructuring accounts for the three months ended March 31, 2015 was as follows:
	(in millions of dollars)	Balance at December 31, 2014		Income			Cash			Non-cash			Balance at March 31, 2015

Income Taxes	Income Taxes
	The reconciliation of income taxes for the three month periods ended March 31, 2015 and 2014, computed at the U.S. federal statutory income tax rate, compared to our effective income tax rate, was as follows:
		Three Months Ended March 31,
	(in millions of dollars)	2015			2014
	Income tax benefit computed at U.S. statutory income tax rate (35%)	$	(2.0	)	$	(3.7	)
	Interest on Brazilian Tax Assessment	0.7			0.7
	Miscellaneous	1.4			0.1
	Income tax expense (benefit) as reported	$	0.1		$	(2.9	)
	Effective tax rate	(1.8		)%	27.1		%
	For the three months ended March 31, 2015, we recorded an income tax expense of $0.1 million on a loss before taxes of $5.7 million. For the three months ended March 31, 2014, we reported an income tax benefit of $2.9 million on a loss before taxes of $10.7 million. The increase in income tax expense in 2015 was primarily due to interest expense on certain foreign tax disputes and unrealized tax benefits related to stock compensation.
	The U.S. federal statute of limitations remains open for the year 2011 and forward. Foreign and U.S. state jurisdictions have statutes of limitations generally ranging from 2 to 5 years. Years still open to examination by foreign tax authorities in major jurisdictions include Australia (2010 forward), Brazil (2009 forward), Canada (2007 forward) and the U.K. (2012 forward). We are currently under examination in various foreign jurisdictions.
	Income Tax Assessment
	In connection with our May 1, 2012 acquisition of Mead Consumer and Office Products Business ("Mead C&OP") we assumed all of the tax liabilities for the acquired foreign operations including Tilibra Produtos de Papelaria Ltda. ("Tilibra"). In December of 2012, the Federal Revenue Department of the Ministry of Finance of Brazil ("FRD") issued a tax assessment (the "Brazilian Tax Assessment") against Tilibra, which challenged the tax deduction of goodwill from Tilibra's taxable income for the year 2007. A second assessment challenging the deduction of goodwill from Tilibra's taxable income for the years 2008, 2009 and 2010 was issued by FRD in October 2013.
	Tilibra is disputing both of the tax assessments 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 ultimately prevail. We are in the early stages of the process to challenge the FRD's tax assessments, and the ultimate outcome will not be determined until the Brazilian tax appeal process is complete, which is expected to take a number of years. In addition, Tilibra's 2011-2012 tax years remain open and subject to audit, and there can be no assurances that we will not receive additional tax assessments regarding the goodwill for one or more of those years. With respect to years 2007 to 2012 we have accrued a total of R104.7 million ($32.5 million based on current exchange rates) of tax, penalties and interest. If the FRD's initial position is ultimately sustained, the amount assessed would materially 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 of this 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 (at December 31, 2012 exchange rates) in consideration of this contingency, of which $43.3 million was recorded as an adjustment to the purchase price and which included the 2008-2012 tax years plus interest and penalties through December 2012. 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 are more likely than not to prevail. During the three months ended March 31, 2015 and 2014, we accrued additional interest as a charge to current tax expense of $0.7 million and $0.7 million, respectively.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings per Share
	Total outstanding shares as of March 31, 2015 and 2014 were 110.9 million and 114.1 million, respectively. As part of our approved stock repurchase plan, in the first quarter of 2015, we repurchased and retired 2.1 million shares of common stock. In addition we acquired 0.6 million treasury shares related to tax withholding for share-based compensation. 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.

As a result, reported diluted earnings per share for the three months ended March 31, 2015 and 2014 are the same as basic earnings per share.
	Awards of potentially dilutive shares of common stock pursuant to 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. For the three months ended March 31, 2015 and 2014, these shares were approximately 9.8 million and 8.6 million, 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, British pound 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.
	When hedge accounting is applicable, 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 March 31, 2015 and December 31, 2014, we had cash-flow-designated foreign exchange contracts outstanding with a U.S. dollar equivalent notional value of $76.6 million and $68.4 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 income, net" in the "Condensed Consolidated Statements of Operations" and are largely offset by the change in the current translated 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 December 2016. As of March 31, 2015 and December 31, 2014, we had undesignated foreign exchange contracts outstanding with a U.S. dollar equivalent notional value of $35.6 million and $55.8 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 March 31, 2015 and December 31, 2014:
	(in millions of dollars)	March 31,		December 31,
		2015		2014
	Assets:
	Forward currency contracts	$	3.8	$	4.7
	Liabilities:
	Forward currency contracts	$	0.1	$	0.5
	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 $819.7 million and $800.7 million and the estimated fair value of total debt was $839.7 million and $831.9 million at March 31, 2015 and December 31, 2014, 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.

	ACCO Brands North America and ACCO Brands International
	ACCO Brands North America and ACCO Brands International manufacture, source and sell traditional office products, school supplies and calendar products. ACCO Brands North America comprises the U.S. and Canada, and ACCO Brands International comprises the rest of the world, primarily Northern Europe, Brazil, Australia and Mexico.
	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.
	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 traditional office supply resellers, wholesalers and other retailers, including on-line retailers. We also supply some of our products directly to large commercial and industrial end-users, and provide business machine maintenance and certain repair services. We also supply private label products within the office products sector.

	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. See "Note 9. Income Taxes - Income Tax Assessment" for details on tax assessments issued by the FRD against our acquired indirect subsidiary, Tilibra, which challenged the tax deduction of goodwill from Tilibra's taxable income for the years 2007 through 2010.
	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 condition, 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 federal, state and local laws and regulations concerning the discharge of materials into the environment and the handling, disposal and clean-up of waste materials and otherwise relating to the protection of the environment. It is not possible to quantify with certainty the potential impact of actions regarding environmental matters, particularly remediation and other compliance efforts that we may undertake in the future. In the opinion of our management, compliance with the present environmental protection laws, before taking into account estimated recoveries from third parties, will not have a material adverse effect upon our capital expenditures, financial condition or results of operations.

Subsequent Event	Subsequent Event
	Effective April 28, 2015 (the "Effective Date"), the Company entered into a Second Amended and Restated Credit Agreement, dated as of April 28, 2015 (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 provides for a $600 million, five-year senior secured credit facility, which consists of a $300 million revolving credit facility (the "Restated Revolving Facility") and a $300 million term loan. Specifically, in connection with the Restated Credit Agreement, the Company:
	•	replaced the Company’s existing U.S.-dollar denominated Senior Secured Term A Loan, due May 2018, under the 2013 Credit Agreement, which had an aggregate principal amount of $299 million outstanding immediately prior to the Effective Date, with a new U.S.-dollar denominated Senior Secured Term A Loan, with a maturity date as specified below, in an aggregate original principal amount of $300 million (the "Restated Term A Loan"); and
	•	replaced the $250 million Revolving Facility under the 2013 Credit Agreement with the Restated Revolving Facility, under which approximately $42 million was outstanding immediately following the Effective Date.
	Borrowings under the Restated Term A Loan were used to continue the entire outstanding principal amount of the existing Term A Loan and pay fees associated with the Restated Credit Agreement. The Restated Revolving Facility is expected to be available for working capital and general corporate purposes.
	Borrowings under the Restated Revolving Facility and the Restated Term A Loan will mature on the earlier of (i) April 28, 2020 and (ii) the date that is 180 days prior to the maturity of the Company’s senior unsecured notes, due April 30, 2020, unless such notes are earlier refinanced. Amounts under the Revolving Facility will be non-amortizing. Beginning September 30, 2015, the outstanding principal amount under the Restated Term A Loan will be payable in quarterly installments in an amount representing, on an annual basis, 5.0% of the initial aggregate principal amount of such loan and increasing to 12.5% by September 30, 2018.
	The Restated Credit Agreement permits the Company to seek increases in the size of the Restated Revolving Facility and the Restated Term A Loan prior to maturity by up to $500 million, in the aggregate, subject to certain conditions and lender commitment

Earnings Per Share [Abstract]
Schedule of Weighted Average Number of Shares	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.

	-1	Due to the net loss during the three months ended March 31, 2015 and 2014, the denominator in the diluted earnings per share calculation does not include the effects of the stock awards for which the average market price for the period exceeds the exercise price, as it would result in a less dilutive computation. As a result, reported diluted earnings per share for the three months ended March 31, 2015 and 2014 are the same as basic earnings per share.

[1]	Due to the net loss during the three months ended MarchB 31, 2015 and 2014, the denominator in the diluted earnings per share calculation does not include the effects of the stock awards for which the average market price for the period exceeds the exercise price, as it would result in a less dilutive computation. As a result, reported diluted earnings per share for the three months ended MarchB 31, 2015 and 2014 are the same as basic earnings per share.
