Cautionary Statement Regarding Forward-Looking Statements

Certain statements contained in this Quarterly Report on Form 10-Q other than statements of historical fact, particularly those anticipating future financial performance, business prospects, growth, operating strategies and similar matters, including without limitation, statements concerning the impacts of the COVID-19 pandemic on the Company’s business, operations, results of operations, liquidity and financial condition, are "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. These statements are based on the beliefs and assumptions of management based on information available to us at the time such statements are made. These statements, which are generally identifiable by the use of the words "will," "believe," "expect," "intend," "anticipate," "estimate," "forecast," "project," "plan," and similar expressions, are subject to certain risks and uncertainties, are made as of the date hereof, and we undertake no duty or obligation to update them. Because actual results may differ materially from those suggested or implied by such forward-looking statements, you should not place undue reliance on them when deciding whether to buy, sell or hold the Company's securities.

Our outlook is based on certain assumptions, which we believe to be reasonable under the circumstances. These include, without limitation, assumptions regarding both the near-term and long-term impact of the COVID-19 pandemic on the economy and our business, our customers and the end-users of our products, and other changes in the macro environment; changes in the competitive landscape, including ongoing uncertainties in the traditional office products channels; as well as the impact of fluctuations in foreign currency and acquisitions and the other factors described below.

Among the factors that could cause our actual results to differ materially from our forward-looking statements are: the scope and duration of the COVID-19 pandemic, government actions and other third-party responses to it and the consequences for the global economy, as well as the regional and local economies in which we operate, uncertainties regarding when the risks of the pandemic will subside and how geographies, distribution channels and consumer behaviors will evolve over time in response to the pandemic, and its impact on our business, operations, results of operations and financial condition, including, among others, manufacturing, distribution and supply chain disruptions, reduced demand for our products and services, and the financial condition of our suppliers and customers, including their ability to fund their operations and pay their invoices. Additionally, many of the other risk factors affecting us are currently elevated by, and likely will continue to be elevated by, the COVID-19 pandemic.

Other factors that could affect our results or cause plans, actions and results to differ materially from current expectations are detailed in "Part I, Item 1. Business" and "Part I, Item 1A. Risk Factors" in our Annual Report on Form 10-K for the year ended December 31, 2019, in "Part II, Item 1A. Risk Factors" in our Quarterly Report on Form 10-Q for the quarters ended March 31, 2020 and June 30, 2020, and the discussion under the heading "COVID-19 Impact" as well as the financial statement line item discussions set forth in "Part I, Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations" of this Quarterly Report on Form 10-Q and from time to time in our other Securities and Exchange Commission (the "SEC") filings.

Notes to Condensed Consolidated Financial Statements (Unaudited)

1. Basis of Presentation

As used in this Quarterly Report on Form 10-Q for the quarter ended September 30, 2020, 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 Corporation is responsible for the accuracy and internal consistency of the preparation of the condensed consolidated financial statements and notes contained in this Quarterly Report on Form 10-Q.

The condensed consolidated interim 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 generally accepted accounting principles in the 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, 2019.

The Condensed Consolidated Balance Sheet as of September 30, 2020, the related Consolidated Statements of Income, the Consolidated Statements of Comprehensive Income (Loss), and the Consolidated Statement of Stockholders' Equity for the three and nine months ended September 30, 2020 and 2019 and Condensed Consolidated Statements of Cash Flows for the nine months ended September 30, 2020 and 2019 are unaudited. The December 31, 2019 Condensed Consolidated Balance Sheet data was derived from audited financial statements, but does not include all annual disclosures required by GAAP. The above referenced financial statements included herein were prepared by management 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, 2020 and 2019, and the financial position of the Company as of September 30, 2020. Interim results may not be indicative of results for a full year.

Effective August 1, 2019, we completed the acquisition (the "Foroni Acquisition") of Indústria Gráfica Foroni Ltda. ("Foroni"), a leading provider of Foroni® branded notebooks and paper-based school and office products in Brazil. The purchase price was $41.5 million inclusive of working capital adjustments. The Foroni Acquisition advanced our strategy to expand in faster growing geographies and product categories, add consumer-centric brands and diversify our customer base. The results of Foroni are included in the ACCO Brands International segment effective August 1, 2019. See "Note 3. Acquisitions" for details on the Foroni Acquisition.

The preparation of financial statements in conformity with 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.

2. Recent Accounting Pronouncements and Adopted Accounting Standards

Recent Accounting Pronouncements

In December 2019, the Financial Accounting Standards Board ("FASB") issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which removes certain exceptions for investments, intraperiod allocations and interim calculations, and adds guidance to reduce complexity in accounting for income taxes. ASU 2019-12 is effective for annual periods, and interim periods within those years, beginning after December 15, 2020. The Company is currently evaluating the effects the standard will have on its consolidated financial statements.

There are no other recently issued accounting standards that are expected to have an impact on the Company’s financial condition, results of operations or cash flow.

Recently Adopted Accounting Standards

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, an accounting standard that requires companies to utilize an impairment model (current expected credit loss, or "CECL") for most financial assets measured at amortized cost and certain other financial instruments, which include, but are not limited to, trade and other receivables. This accounting standard replaced the incurred loss model

with a model that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to estimate those losses. Effective January 1, 2020, the Company adopted this standard. The adoption of this standard did not have a material impact on our condensed consolidated financial statements.

There were no other accounting standards that were adopted in the first nine months of 2020 that had a material effect on the Company’s financial condition, results of operations or cash flow.

3. Acquisitions

Acquisition of Foroni

Effective August 1, 2019, we completed the acquisition of Foroni, a leading provider of Foroni® branded notebooks and paper-based school and office products in Brazil. The Foroni Acquisition advanced our strategy to expand in faster growing geographies and product categories, add consumer-centric brands and diversify our customer base. The results of Foroni are included in the ACCO Brands International segment effective August 1, 2019.

The purchase price was R$157.2 million (US$41.5 million based on July 31, 2019, exchange rates) inclusive of working capital adjustments. We also assumed $7.6 million in debt. A portion of the purchase price (R$25.0 million or US$6.6 million based on July 31, 2019 exchange rates) is being held in an escrow account for a period of up to 6 years after closing in the event of any claims against the sellers under the quota purchase agreement. The Company may also make claims against the sellers directly, subject to limitations in the quota purchase agreement, if the escrow is depleted. The Foroni Acquisition and related expenses were funded by cash on hand.

For accounting purposes, the Company was the acquiring enterprise. The Foroni Acquisition is being accounted for as a purchase business combination and Foroni's results are included in the Company’s condensed consolidated financial statements as of August 1, 2019. The additional net sales from Foroni for the one and seven months ended July 31, 2020 were $1.0 million and $16.7 million, respectively.

The Company entered into a Third Amended and Restated Credit Agreement (the "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 agents and various lenders party thereto. The Credit Agreement provided for a five-year senior secured credit facility, which consisted of a €300.0 million (US$320.8 million based on January 27, 2017, exchange rates) term loan facility, an A$80.0 million (US$60.4 million based on January 27, 2017, exchange rates) term loan facility, and a US$400.0 million multi-currency revolving credit facility (the "Revolving Facility").

Effective July 26, 2018, the Company entered into the First Amendment (the "First Amendment") to the Credit Agreement among the Company, certain subsidiaries of the Company, Bank of America, N.A., as administrative agent, and the other lenders party thereto. The First Amendment increased the aggregate revolving credit commitments under the Revolving Facility by $100.0 million such that, after giving effect to such increase, the aggregate amount of revolving credit available under the Revolving Facility was $500.0 million. In addition, the First Amendment also affected certain technical amendments to the Credit Agreement, including the addition of provisions relating to LIBOR successor rate procedures if LIBOR becomes unascertainable or is discontinued in the future and to expressly permit certain intercompany asset transfers. The changes related to LIBOR successor rate procedures are not expected to have a material effect on the Company.

Effective May 23, 2019, the Company entered into a Second Amendment (the "Second Amendment") to the Credit Agreement. Pursuant to the Second Amendment, the Credit Agreement was amended to, among other things:

•extend the maturity date to May 23, 2024;

•increase the aggregate revolving credit commitments under the Revolving Facility from $500.0 million to $600.0 million;

•establish a new term loan facility denominated in U.S. Dollars in an aggregate principal amount of $100.0 million (the "USD Term Loan");

•replace the minimum fixed coverage ratio of 1.25:1.00 with a minimum interest coverage ratio, as calculated under the Credit Agreement, of 3.00:1.00;

13

ACCO Brands Corporation and Subsidiaries

Notes to Condensed Consolidated Financial Statements (Unaudited) (Continued)

•reflect a more favorable restricted payment covenant, with the consolidated leverage ratio hurdle for unlimited restricted payments (including share repurchases and dividends) as calculated under the Credit Agreement increasing from 2.50:1.00 to 3.25:1.00;

•reflect, in certain cases, more favorable pricing with a 25-basis point reduction in the applicable rate on outstanding loans than was in effect prior to the Second Amendment based on the Company's current consolidated leverage ratio, along with lower fees on undrawn amounts;

•eliminate the requirement to make annual principal prepayments of excess cash flow;

•reduce amortization payments for the term loans; and

•increase the qualified receivables transaction basket with respect to sales or financings of certain receivables.

Effective upon the closing of the Second Amendment, the Company borrowed the entire principal amount committed under the USD Term Loan, which was used to repay revolver borrowings and, in combination with the increase in the Revolving Facility, resulted in $200.0 million of additional liquidity becoming available under the Revolving Facility.

On May 1, 2020, the Company entered into a Third Amendment (the "Third Amendment") to its Credit Agreement, among the Company, certain subsidiaries of the Company, Bank of America, N.A., as administrative agent, and the other lenders party thereto. Pursuant to the Third Amendment, the Credit Agreement was amended to, among other things:

•increase the maximum consolidated leverage ratio from 3.75:1.00 to 4.75:1.00, stepping back down to 3.75:1.00 for the first fiscal quarter ending after June 30, 2021;

•amend the pricing based on the Company’s consolidated leverage ratio, with a scaled increase in fees as follows, effective May 1, 2020:

Leverage Ratio	Applicable Rate	Undrawn Fee
> 4.25 to 1.00	2.75%	0.500%
≤ 4.25 to 1.00 and > 4.00 to 1.00	2.50%	0.500%
≤ 4.00 to 1.00 and > 3.50 to 1.00	2.25%	0.375%
≤ 3.50 to 1.00 and > 3.25 to 1.00	2.00%	0.375%
≤ 3.25 to 1.00 and > 3.00 to 1.00	1.75%	0.300%
≤ 3.00 to 1.00 and > 2.00 to 1.00	1.50%	0.250%
≤ 2.00 to 1.00	1.25%	0.200%

Per the terms of the Third Amendment, pricing will be locked at LIBOR plus 2.00% until the Company publishes its financial results for the fiscal quarter ended June 30, 2020;

•Reduce the Company’s capacity to incur certain other indebtedness, and impose additional limitations on certain restricted payments (other than dividends) and permitted acquisitions; and

•Require that the Company pay down any amounts on the Revolving Facility when cash and cash equivalents of the loan parties exceed $100.0 million.

As of September 30, 2020, there were $123.7 million in borrowings outstanding under the Revolving Facility. The remaining amount available for borrowings was $465.5 million (allowing for $10.8 million of letters of credit outstanding on that date).

As of and for the periods ended September 30, 2020 and December 31, 2019, the Company was in compliance with all applicable loan covenants.

5. Leases

The Company leases its corporate headquarters, various other facilities for distribution, manufacturing, and offices, as well as vehicles, forklifts and other equipment. The Company determines if an arrangement is a lease at inception. Leases are included in "Right of use asset, leases" ("ROU Assets"), and the current portion of the lease liability is included in "Lease liabilities" and the non-current portion is included in "Long-term lease liabilities" in the Condensed Consolidated Balance Sheet. The Company currently has an immaterial amount of financing leases and leases with terms of more than one month and less than 12 months. ROU Assets and lease liabilities are recognized based on the present value of lease payments over the lease term. Because most of the Company’s leases do not provide an implicit rate of return, the Company uses its incremental collateralized borrowing rate, on a regional basis, in determining the present value of lease payments. The incremental borrowing rate is dependent upon the duration of the lease and has been segmented into three groups of time. All leases within the same region and the same group of time share the same incremental borrowing rate. The Company has lease agreements with lease and non-lease components, which are combined for accounting purposes for all classes of assets except information technology equipment.

The components of lease expense were as follows:

	Three Months Ended September 30,				Nine Months Ended September 30,
(in millions)	2020		2019		2020		2019
Operating lease cost	$	6.7	$	7.3	$	21.0	$	21.7
Sublease income	(0.2)		(0.5)		(0.9)		(1.3)
Total lease cost	$	6.5	$	6.8	$	20.1	$	20.4

Other information related to leases was as follows:

7. Stock-Based Compensation

The following table summarizes our stock-based compensation expense (including stock options, restricted stock units ("RSUs") and performance stock units ("PSUs")) for the three and nine months ended September 30, 2020 and 2019:

	Three Months Ended September 30,				Nine Months Ended September 30,
(in millions)	2020		2019		2020		2019
Stock option compensation expense	$	0.5	$	0.7	$	2.1	$	2.0
RSU compensation expense	1.3		1.2		4.3		4.1
PSU compensation expense	—		(1.0)		(1.2)		0.2
Total stock-based compensation expense	$	1.8	$	0.9	$	5.2	$	6.3

We generally recognize compensation expense for stock-based awards ratably over the vesting period. Stock-based compensation expense for each of the nine months ended September 30, 2020 and 2019 includes $1.0 million of expense related to stock awards granted to eligible non-employee directors, which were fully vested on the grant date. During the third quarter of 2020, the Compensation Committee of the Company's Board of Directors approved stock compensation grants which consisted of 34,359 stock options, 10,311 RSUs and 20,618 PSUs.

The following table summarizes our unrecognized compensation expense and the weighted-average period over which the expense will be recognized as of September 30, 2020:

	September 30, 2020
	Unrecognized	Weighted Average

Work in process	3.8		3.5
Finished goods	253.9		235.4
Total inventories	$	300.5	$	283.3

9. Goodwill and Identifiable Intangible Assets

Goodwill

We test goodwill for impairment at least annually, during the second quarter, and on an interim basis if an event or circumstance indicates that there is a triggering event that would make it more likely than not that an impairment loss had been incurred.

During the second quarter ended June 30, 2020, we performed a qualitative assessment of impairment for goodwill for each of our three reporting units. We considered events and circumstances that may affect the fair value of each reporting unit to determine whether it is necessary to perform the quantitative impairment test. We focused on events or circumstances that could affect the significant inputs, including, but not limited to, financial performance, such as negative or declining cash flows, a decline in actual or planned revenue or earnings compared with actual and projected results of relevant prior periods, competitive, economic, industry and market considerations, and other factors that have or could impact each of our reporting

17

ACCO Brands Corporation and Subsidiaries

Notes to Condensed Consolidated Financial Statements (Unaudited) (Continued)

units. If we determine that it is more likely than not that the goodwill is impaired, then we would perform a quantitative impairment test.

The results of our qualitative assessment performed during the second quarter ended June 30, 2020, was that there were no triggering events that would make it more likely than not that an impairment loss to our goodwill has been incurred for any of our three reporting units.

Changes in the net carrying amount of goodwill by segment were as follows:

(in millions)	ACCO Brands North America		ACCO Brands EMEA		ACCO Brands International		Total
Balance at December 31, 2019	$	375.6	$	165.7	$	177.3	$	718.6
Acquisitions	—		—		3.9		3.9
Foreign currency translation	—		5.2		(4.3)		0.9
Balance at September 30, 2020	$	375.6	$	170.9	$	176.9	$	723.4

The goodwill balance is net of $215.1 million of accumulated impairment losses, which occurred prior to December 31, 2016.

Identifiable Intangible Assets

Foroni Acquisition

The valuation of identifiable intangible assets of $11.1 million acquired in the Foroni Acquisition includes an amortizable trade name, "Foroni®," which has been recorded at its estimated fair value. The fair value of the trade name was determined using the relief from royalty method, which is based on the present value of royalty fees derived from projected revenues. The Foroni® trade name is expected to be amortized over 23 years on a straight-line basis.

The gross carrying value and accumulated amortization by class of identifiable intangible assets as of September 30, 2020 and December 31, 2019, was as follows:

	September 30, 2020							December 31, 2019
(in millions)	Gross Carrying Amounts		Accumulated Amortization			Net Book Value		Gross Carrying Amounts		Accumulated Amortization			Net Book Value
Indefinite-lived intangible assets:
Trade names	$	458.5	$	(44.5)	(1)	$	414.0	$	467.3	$	(44.5)	(1)	$	422.8
Amortizable intangible assets:
Trade names	315.2		(93.3)			221.9		316.7		(83.7)			233.0
Customer and contractual relationships	245.2		(158.3)			86.9		241.0		(142.3)			98.7
Patents	5.8		(1.8)			4.0		5.5		(1.4)			4.1
Subtotal	566.2		(253.4)			312.8		563.2		(227.4)			335.8
Total identifiable intangibles	$	1,024.7	$	(297.9)		$	726.8	$	1,030.5	$	(271.9)		$	758.6

(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 $7.9 million and $8.6 million for the three months ended September 30, 2020 and 2019, respectively, and $24.1 million and $26.8 million for the nine months ended September 30, 2020 and 2019, respectively.

18

ACCO Brands Corporation and Subsidiaries

Notes to Condensed Consolidated Financial Statements (Unaudited) (Continued)

Estimated amortization expense for amortizable intangible assets as of September 30, 2020, for the current year and the next five years is as follows:

(in millions)	2020		2021		2022		2023		2024		2025
Estimated amortization expense(2)	$	32.0	$	28.4	$	24.9	$	22.6	$	21.0	$	19.4

(2)    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. We performed this annual assessment, on a qualitative basis, as allowed by GAAP, for our indefinite-lived trade names in the second quarter of 2020 and concluded that no impairment existed.

COVID-19 Impact

We continue to monitor the significant global impact and uncertainty as a result of COVID-19 to assess the outlook for demand for our products and the effect on our business and our overall financial performance. This includes our risk of impairment of our goodwill and indefinite-lived intangible assets. Although the full impact of COVID-19 on demand remains uncertain, with impact varying significantly by geographic region, we remain committed to taking the actions necessary to protect our long-term financial performance expectations and position the Company for long-term growth. We expect the macroeconomic environment will recover in the medium to long-term. As a result of our analysis, and consideration of events and circumstances, we concluded based on the previously conducted annual assessment, on a qualitative basis, no impairment of our goodwill or indefinite-lived intangible assets was triggered as of June 30, 2020.

The implied fair values of all three of our reporting units, more likely than not, exceed their carrying values at September 30, 2020. In addition, we have not identified a triggering event that would cause us to perform a quantitative goodwill impairment analysis. In management’s opinion, the goodwill balance for our ACCO Brands International reporting unit could be at risk for impairment if operating performance does not recover as expected from the current impacts of COVID-19, if we experience negative changes to the long-term outlook for the business, or changes in factors and assumptions which impact the fair value of our reporting units such as low or declining revenue growth rates, depressed operating margins or adverse changes to the discount rates impacting this report unit.

10. Restructuring

The Company recorded $7.3 million and $4.8 million of restructuring expense for the nine months ended September 30, 2020 and 2019, respectively, and recorded $0.5 million and $2.1 million of restructuring expense for the three months ended September 30, 2020 and 2019, respectively. Restructuring charges in 2020 were primarily related to severance costs in North America. Additional severance charges were also taken in Mexico, Brazil, EMEA and Australia. The restructuring expenses in 2019 were primarily for severance costs related to cost reduction initiatives in our North America and International segments.

11. Income Taxes

For the three months ended September 30, 2020, we recorded an income tax expense of $6.8 million on income before taxes of $25.6 million, for an effective rate of 26.6 percent. The decrease in the effective rate versus the three months ended September 30, 2019 was primarily driven by an accrual made in the prior year of $1.6 million of Brazilian income taxes on a contingent gain.

For the three months ended September 30, 2019, we recorded an income tax expense of $12.2 million on income before taxes of $40.2 million, for an effective rate of 30.3 percent.

For the nine months ended September 30, 2020, we recorded an income tax expense of $13.7 million on income before taxes of $45.9 million, for an effective rate of 29.8 percent. The decrease in the effective rate versus the nine months ended September 30, 2019 was primarily due to an increase in reserves for uncertain tax positions in the prior year, Brazilian income taxes accrued on a contingent gain and a decrease in non-deductible interest in the current year.

For the nine months ended September 30, 2019, we recorded an income tax expense of $38.1 million on income before taxes of $101.4 million, for an effective rate of 37.6 percent. The high effective tax rate for the period was primarily due to the Company increasing its reserves for uncertain tax positions in connection with the Brazil Tax Assessments (see Brazil Tax Assessments below) in the amount of $5.6 million, the accrual of $1.6 million of Brazilian income taxes on a contingent gain, and the recording of deferred state taxes on unremitted non-U.S. earnings in the amount of $0.8 million and other reserves related to various tax contingencies.

The U.S. federal statute of limitations remains open for the years 2016 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 (2016 forward), Brazil (2015 forward), Canada (2016 forward), Germany (2015 forward), Sweden (2015 forward) and the U.K. (2018 forward). We are currently under examination in certain foreign jurisdictions.

Final Section 951A Tax Regulations

On July 20, 2020, the U.S. Department of the Treasury and the Internal Revenue Service issued final section 951A regulations ("Final Regulations") on an election to exclude high-tax global intangible low-taxed income ("GILTI") from a U.S.

shareholder’s gross income. As of the end of the third quarter, we are not expecting that application of the Final Regulations will have a material impact on the Company’s effective tax rate.

Brazil Tax Assessments

In connection with our May 1, 2012, acquisition of the 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 against Tilibra, challenging the tax deduction of goodwill from Tilibra's taxable income for the year 2007 (the "First Assessment"). 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 (the "Second Assessment" and together with the First Assessment, the "Brazil Tax Assessments"). Tilibra is disputing both of the Brazil Tax Assessments.

The final administrative appeal of the Second Assessment was decided against the Company in 2017. In 2018, we decided to appeal this decision to the judicial level. In the event we do not prevail at the judicial level, we will be required to pay an additional penalty representing attorneys' costs and fees; accordingly, in the first quarter of 2019, the Company recorded an additional reserve in the amount of $5.6 million. In connection with the judicial challenge, we were required to provide security to guarantee payment of the Second Assessment should we not prevail.

In the third quarter of 2020, the final administrative appeal of the First Assessment was decided against the Company. We have decided to appeal this decision to the judicial level. We recorded an additional expense in the quarter of $1.2 million representing additional attorneys' costs and fees, which we will be required to pay if we do not prevail at the judicial level.

We believe we have meritorious defenses and intend to vigorously contest both of the Brazil Tax Assessments; however, there can be no assurances that we will ultimately prevail. The ultimate outcome will not be determined until the Brazilian tax appeal process is complete, which is expected to take a number of years. If the FRD's initial position is ultimately sustained, payment of 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 these disputes 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 2007-2012 tax years plus penalties and interest through December 2012. Included in this reserve is an assumption of penalties at 75 percent, which is the standard penalty. While there is a possibility that a penalty of 150 percent could be imposed in connection with the First Assessment, based on the facts in our case and existing precedent, we believe the likelihood of a 150 percent penalty is not more likely than not as of September 30, 2020. We will continue to actively monitor administrative and judicial court decisions and evaluate their impact, if any, on our legal assessment of the ultimate outcome of our disputes. 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. The time limit for issuing an assessment for 2011 and 2012 expired in January 2018 and January 2019, respectively. Since we did not receive an assessments for either of these periods, we reversed the amounts previously accrued, including $5.6 million related to 2011, which was reversed in the first quarter of 2018. During the three months ended September 30, 2020 and 2019, we accrued additional interest as a charge to income tax expense of $0.1 million and $0.3 million, respectively, and for the nine months ended September 30, 2020 and 2019, we accrued additional interest as a charge to current income tax expense of $0.3 million and $0.9 million, respectively. At current exchange rates, our accrual through September 30, 2020, including tax, penalties and interest is $26.1 million (reported in "Other non-current liabilities").

12. Earnings per Share

Total outstanding shares as of September 30, 2020 and 2019, were 94.5 million and 97.2 million, respectively. Under our stock repurchase program, for the three months ended September 30, 2020 no shares were repurchased and for the nine months ended September 30, 2020 we repurchased and retired 2.7 million shares. Under our stock repurchase program, for the three and nine months ended September 30, 2019, we repurchased and retired 2.3 million and 7.0 million shares, respectively. For the nine months ended September 30, 2020 and 2019, we acquired 0.2 million and 0.5 million shares, respectively, related to tax withholding for share-based compensation.

The calculation of basic earnings per share of common stock is based on the weighted-average number of shares of common stock outstanding in the year, or period, over which they were outstanding. Our calculation of diluted earnings per share of common stock assumes that any shares of common stock outstanding were increased by shares that would be issued upon exercise of those stock awards 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.

Our weighted-average shares outstanding for the three and nine months ended September 30, 2020 and 2019 was as follows:

	Three Months Ended September 30,		Nine Months Ended September 30,
(in millions)	2020	2019	2020	2019
Weighted-average number of shares of common stock outstanding - basic	94.5	97.6	95.0	100.4
Stock options	—	0.4	0.1	0.4
Restricted stock units	1.1	0.9	1.1	1.1
Weighted-average shares and assumed conversions - diluted	95.6	98.9	96.2	101.9

Awards of potentially dilutive shares of common stock, 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 and nine months ended September 30, 2020, the number of anti-dilutive shares was approximately 8.0 million and 7.5 million, respectively. For the three and nine months ended September 30, 2019, the number of anti-dilutive shares was approximately 5.0 million and 4.7 million, respectively.

13. 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 against the U.S. dollar include the Euro, Australian dollar, Canadian dollar, Swedish krona, 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, on the date 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 with third parties 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 (the Euro, the Swedish krona and the British pound), Brazil, Australia, Canada, and Mexico.

22

ACCO Brands Corporation and Subsidiaries

Notes to Condensed Consolidated Financial Statements (Unaudited) (Continued)

Forward currency contracts are used to hedge foreign denominated inventory purchases for Europe, Australia, Canada, Japan and New Zealand, and are designated as cash flow hedges. Unrealized gains and losses on these contracts are deferred in Accumulated Other Comprehensive Income ("AOCI") until the contracts are settled and the underlying hedged transactions relating to inventory purchases are recognized, at which time the deferred gains or losses will be reported in the "Cost of products sold" line in the "Consolidated Statements of Income." As of September 30, 2020 and December 31, 2019, we had cash flow foreign exchange contracts outstanding with a U.S. dollar equivalent notional value of $108.4 million and $96.7 million, respectively, which were designated as hedges.

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 (income), net" in the "Consolidated Statements of Income" 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 May 2024. As of September 30, 2020 and December 31, 2019, we had foreign exchange contracts outstanding with a U.S. dollar equivalent notional value of $171.0 million and $182.6 million, respectively, which were not designated as hedges.

The following table summarizes the fair value of our derivative financial instruments as of September 30, 2020 and December 31, 2019:

	Fair Value of Derivative Instruments
	Derivative Assets					Derivative Liabilities
(in millions)	Balance Sheet Location	September 30, 2020		December 31, 2019		Balance Sheet Location	September 30, 2020		December 31, 2019

14. 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.

24

ACCO Brands Corporation and Subsidiaries

Notes to Condensed Consolidated Financial Statements (Unaudited) (Continued)

We have determined that our financial assets and liabilities described in "Note 13. Derivative Financial Instruments" 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, 2020 and December 31, 2019:

(in millions)	September 30, 2020		December 31, 2019
Assets:
Forward currency contracts	$	21.9	$	8.0
Liabilities:
Forward currency contracts	$	22.8	$	9.5

Our forward currency contracts are included in "Other current assets," "Other current liabilities," "Other non-current assets," or "Other non-current liabilities." The forward foreign currency exchange contracts are primarily valued based on the foreign currency spot and forward rates quoted by 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 $917.3 million and $816.0 million and the estimated fair value of total debt was $926.7 million and $831.4 million at September 30, 2020 and December 31, 2019, 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 time to maturity.

15. Accumulated Other Comprehensive Income (Loss)

AOCI is defined as net income (loss) and other changes in stockholders’ equity from transactions and other events from sources other than stockholders. The components of, and changes in, AOCI were as follows:

(in millions)	Derivative Financial Instruments		Foreign Currency Adjustments		Unrecognized Pension and Other Post-retirement Benefit Costs		Accumulated Other Comprehensive Income (Loss)
Balance at December 31, 2019	$	(0.2)	$	(299.5)	$	(206.0)	$	(505.7)

(1)     These AOCI components are included in the computation of net periodic benefit cost for pension and post-retirement plans. See "Note 6. Pension and Other Retiree Benefits" for additional details.

16. Revenue Recognition

Revenue is recognized when control of the promised goods or services is transferred to our customers in an amount reflective of the consideration we expect to receive in exchange for those goods or services. Taxes we collect concurrent with revenue producing activities are excluded from revenue. Incidental items incurred that are immaterial in the context of the contract are expensed.

At the inception of each contract, the Company assesses the products and services promised and identifies each distinct performance obligation. To identify the performance obligations, the Company considers all products and services promised regardless of whether they are explicitly stated or implied within the contract or by standard business practices.

Freight and distribution activities performed before the customer obtains control of the goods are not considered promised services under customer contracts and therefore are not distinct performance obligations. The Company has chosen to account for shipping and handling activities as a fulfillment activity, and therefore accrues the expense of freight and distribution in "Cost of products sold" when product is shipped.

Service or Extended Maintenance Agreements ("EMAs"). As of December 31, 2019, there was $5.5 million of unearned revenue associated with outstanding EMAs, primarily reported in "Other current liabilities." During the three and nine months ended September 30, 2020, $0.7 million and $4.8 million of the unearned revenue was earned and recognized, respectively. As of September 30, 2020, the amount of unearned revenue from EMAs was $3.3 million. We expect to earn and recognize approximately $2.6 million of the unearned amount in the next 12 months and $0.7 million in periods beyond the next 12 months.

17. Information on Business Segments

The Company has three operating business segments each of which is comprised of different geographic regions. The Company's three segments are as follows:

Operating Segment	Geography	Primary Brands	Primary Products
ACCO Brands North America	United States and Canada	Five Star®, Quartet®, AT-A-GLANCE®, GBC®, Swingline®, Kensington®, Mead®, and Hilroy®	School notebooks, planners, dry erase boards, storage and organization products (3-ring binders), stapling, punching, laminating, binding products, and computer accessories
ACCO Brands EMEA	Europe, Middle East and Africa	Leitz®, Rapid®, Esselte®, Kensington®, Rexel® GBC®, NOBO®, and Derwent®	Storage and organization products (lever-arch binders, sheet protectors, indexes), stapling, punching, laminating, shredding, do-it-yourself tools, dry erase boards, writing instruments and computer accessories
ACCO Brands International	Australia/N.Z., Latin America and Asia-Pacific	Tilibra®, GBC®, Barrilito®, Foroni®, Marbig®, Kensington®, Artline®*, Wilson Jones®, Quartet®, Spirax®, and Rexel® *Australia/N.Z. only	School notebooks, planners, dry erase boards, storage and organization products (binders, sheet protectors and indexes), stapling, punching, laminating, shredding, writing instruments, janitorial supplies and computer accessories

Each business segment designs, markets, sources, manufactures and sells recognized consumer and other end-user demanded branded products used in businesses, schools and homes. Product designs are tailored to end-user preferences in each geographic region, and where possible, leverage common engineering, design, and sourcing.

Our product categories include storage and organization; stapling; punching; laminating, shredding and binding machines; dry erase boards; notebooks; calendars; computer accessories; and do-it-yourself tools, among others. Our portfolio includes both globally and regionally recognized brands. The revenue in North America and International segments includes significant sales of consumer products that have very important, seasonal selling periods related to back-to-school and calendar year-end. For North America and Mexico, back-to-school straddles the second and third quarters, and for the Southern Hemisphere it takes place in the fourth and first quarter. We expect sales of consumer products to become a greater percentage of our revenue because demand for consumer back-to-school products is growing faster than demand for most business-related and calendar products.

Customers

We distribute our products through a wide variety of retail and commercial channels to ensure that they are readily and conveniently available for purchase by consumers and other end-users, wherever they prefer to shop. These channels include mass retailers; e-tailers; discount, drug/grocery and variety chains; warehouse clubs; hardware and specialty stores; independent office product dealers; office superstores; wholesalers; and contract stationers. We also sell directly to commercial and consumer end-users through our e-commerce sites and our direct sales organization.

18. Commitments and Contingencies

Pending Litigation - Brazil Tax Assessments

In connection with our May 1, 2012, acquisition of the Mead C&OP business, we assumed all of the tax liabilities for the acquired foreign operations including Tilibra. For further information, see "Note 11. Income Taxes - Brazil Tax Assessments" for details on tax assessments issued by the FRD against Tilibra challenging the tax deduction of goodwill from Tilibra's taxable income for the years 2007 through 2010. If the FRD's initial position is ultimately sustained, payment of the amount assessed would materially and adversely affect our cash flow in the year of settlement.

Brazil Tax Credits

In March 2017, the Supreme Court of Brazil ruled against the Brazilian tax authority in a leading case related to the computation of certain indirect taxes. The Supreme Court ruled that the indirect tax base should not include a value-added tax known as "ICMS." The Supreme Court decision, in principle, affects all applicable judicial proceedings in progress, and reduces future indirect taxes on our Brazilian subsidiary, Tilibra. However, the Brazilian tax authority has filed an appeal seeking clarification of certain matters, including the amount by which taxpayers would be entitled to reduce their indirect tax base (i.e. the gross ICMS collected or the net ICMS paid). The appeal also requests a modulation of the decision’s effects, which may limit its retrospective impact on taxpayers, including Tilibra.

Tilibra has paid and continues to pay these indirect taxes on a tax base which includes the gross ICMS collected. It has also filed legal actions in Brazil to request reimbursement of these excess tax payments by way of future credits ("Tax Credits") and for permission to exclude the gross ICMS collected from the tax base in future periods. Tilibra’s legal actions cover various

time periods and some have been finally decided in a court of law in favor of Tilibra, while others are still pending a final decision.

Due to the uncertainties associated with the scope of the application of the Brazilian Supreme Court’s ruling, taking into account the Brazilian tax authority’s appeal and request for modulation, the Company has and will recognize income only for the amount of Tax Credits actually monetized, which will occur when Tilibra receives a cash flow benefit from applying the Tax Credits against various taxes payable in Brazil. The benefit of the Tax Credits realized by the Company has and will be recorded in the Consolidated Statements of Income in the line item "Other expense (income), net."

Tilibra received final decisions for Tax Credits in the amount of $4.3 million, of which $3.3 million was offset against Brazilian taxes in the fourth quarter of 2019, with the balance used during the first quarter of 2020. This amount of Tax Credits assumes that only the net amount of ICMS paid can be excluded from the tax base. The total value of these Tax Credits was recorded as a gain in Tilibra’s local statutory accounts during the third quarter of 2019, resulting in Brazilian federal taxes payable of approximately $1.6 million.

Final decisions in the remaining legal actions Tilibra has filed may result in additional Tax Credits that could be monetized in future periods. Further, a favorable decision in the leading case by the Brazilian Supreme Court on the methodology to compute the Tax Credits (i.e. gross ICMS collected) would result in additional Tax Credits being available to Tilibra. The amount of these additional Tax Credits may be material.

Foroni, in years prior to the acquisition, also filed legal actions in Brazil to recover these excess indirect tax payments; however, all of Foroni's claims are still pending a final decision. In the event any Tax Credits are recovered on behalf of Foroni, we are required under the quota purchase agreement to remit such recovery to the former owners of Foroni on a net income tax paid basis, and therefore will not recognize any benefit in the Consolidated Statements of Income.

Other Pending Litigation

We are party to various lawsuits and regulatory proceedings, primarily related to alleged patent infringement, as well as other 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 costly and time-consuming and might require us to pay monetary damages or enter into costly license agreements. We also may be subject to injunctions against development and sale of certain of our products.

It is the opinion of management that (other than the Brazil Tax Assessments) the ultimate resolution of currently outstanding matters will 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 be successful in our 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.

Environmental

We are subject to national, state, provincial and/or local environmental laws and regulations concerning the discharge of materials into the environment and the handling, disposal and clean-up of waste materials and other items relating to the protection of the environment. This includes environmental laws and regulations that affect the design and composition of certain of our products. 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 and results of operations or competitive position.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Introduction

Management’s Discussion and Analysis of Financial Condition and Results of Operations for the three and nine months ended September 30, 2020 and 2019 should be read in conjunction with the unaudited condensed consolidated financial statements of ACCO Brands Corporation and the accompanying notes contained therein.

Overview of the Company

ACCO Brands designs, markets and manufactures well-recognized consumer, school, and office products. Our widely known brands include AT-A-GLANCE®, Barrilito®, Derwent®, Esselte®, Five Star®, Foroni®, GBC®, Hilroy®, Kensington®, Leitz®, Marbig®, Mead®, NOBO®, Quartet®, Rapid®, Rexel®, Swingline®, Tilibra® and Wilson Jones®. Approximately 75 percent of our net sales come from brands that occupy the No. 1 or No. 2 position in the product categories in which we compete. We distribute our products through a wide variety of retail and commercial channels to ensure that our products are readily and conveniently available for purchase by consumers and other end-users, wherever they prefer to shop. These channels include mass retailers; e-tailers; discount, drug/grocery and variety chains; warehouse clubs; hardware and specialty stores; independent office product dealers; office superstores; wholesalers; and contract stationers. Our products are sold primarily in the U.S., Europe, Brazil, Australia, Canada, and Mexico. For the year ended December 31, 2019, approximately 43 percent of our net sales were in the U.S.

Our leading product category positions provide the scale to invest in marketing and product innovation to drive profitable growth. Over the long term, we expect to derive much of our growth from emerging markets such as Latin America and parts of Asia, the Middle East, and Eastern Europe. In all of our markets, we see opportunities for sales growth through share gains, channel expansion, and product enhancements.

Our strategy is to grow our global portfolio of consumer brands, offer more innovative products, increase our presence in faster growing geographies and channels, and diversify our customer base. We plan to supplement organic growth with strategic acquisitions in both existing and adjacent product categories. We generate strong operating cash flow, and will continue to leverage our cost structure through synergies and productivity savings to drive long-term profit improvement.

In support of these strategic imperatives, we have been transforming our business by acquiring companies with consumer and other end-user demanded brands, diversifying our distribution channels and increasing our global presence. These acquisitions have meaningfully expanded our portfolio of well-known brands, enhanced our competitive position from both a product and channel perspective, and added scale to our operations. Today ACCO Brands is a global enterprise focused on developing innovative, branded consumer products for use in businesses, schools, and homes.

Overview of Performance

As used in this Quarterly Report on Form 10-Q, "COVID-19 impacts" include the operational, financial, and other effects on ACCO Brands, its customers and end users of its products, of school and business closures, work from home, remote and hybrid learning, government orders and manufacturing, distribution and supply chain and other disruptions resulting from COVID-19 and the actions ACCO Brands, its customers and end users have taken in response to the pandemic, including actions we have taken to manage our inventory and credit risk under the circumstances.

The COVID-19 impacts on our business have varied and continue to vary significantly by geographic region and country depending upon a range of factors, including how seriously the pandemic is affecting public health in the country and whether and to what degree businesses and schools are open, the general seasonality of our business in that country, the nature and level of government support, and the channel structure. During the third quarter, all segments were impacted by COVID-19, but EMEA experienced lower impacts and our International segment experienced, and continues to experience, the highest impacts, largely in Latin America due to the seriousness of the pandemic and the dependence of our Brazilian and Mexican businesses on the sale of school products. In North America, following good sell-in of back-to-school products in the second quarter, our third quarter sales were adversely affected by weaker sell through as many school districts chose to delay or not issue school purchase lists that normally drive back-to-school consumer demand.

Our third quarter net sales declined $61.6 million, or 12.2 percent primarily from COVID-19 impacts. Operating income declined 29.7 percent, primarily due to the lower sales, partially offset by company-wide cost reductions and government assistance in certain countries, generally in return for maintaining employment, pay and benefits. Foreign exchange had a

31

minimal impact on sales as the Euro, British pound, and Australian dollar moved favorably, while Latin American currencies deteriorated. From a profit perspective, foreign exchange provided a $1 million benefit.

Operating cash inflow for the nine months ended September 30, 2020, was $21.8 million, compared with last year's operating cash inflow of $75.1 million. The $53.3 million year-over-year difference was due to lower net income and more cash used for working capital.

COVID-19 Impact

COVID-19 and the actions being taken by national, state and local governments, businesses, schools and others to address it (including work from home, quarantines, travel restrictions, business and school closure, remote learning, and cancellations of, and limitations on, public gatherings) have caused and continue to cause significant disruptions to normal business operations and have had, and are expected to continue to have, significant adverse impacts on our customers and end-users worldwide. Similarly, our business, sales, earnings, and results of operations have been and will continue to be materially adversely affected by these events, as well as the current and expected continued negative impact on the global economy and uncertainties regarding when the risks of the pandemic will subside and how geographies, distribution channels and consumer behaviors will evolve over time in response to the pandemic.

Health and Safety of Our People

Our top priority is the health and safety of our employees and we continue to follow all of the modified operating procedures we implemented earlier this year to address their safety. We will continue to modify our operations based on local conditions and consistent with government mandates regarding employee health and safety and make changes as appropriate.

During the third quarter, most of our office and administrative employees continued to work from home, but many employees outside North America, particularly in EMEA, began returning to work in our offices. We have implemented modifications to our normal office procedures similar to those used at our plants and distribution facilities to protect the health and safety of our employees returning to our office locations.

Facilities and Supply Chain

During the first quarter, COVID-19 impacted our Chinese supply chain and we experienced some out-of-stocks and lost sales, but we began to see improvement early in the second quarter and we had no significant supply chain issues in meeting our back-to-school orders in North America during the second or third quarter. During the third quarter, we continued manufacturing and shipping at reduced levels based on lower demand in our North America and International segments.

We currently believe the most significant facilities and supply chain issues are behind us, but there can be no assurance that there will not be future disruptions (including closures) or a reemergence of facilities and supply chain impacts as a result of COVID-19.

Cost Reductions

To begin to address the financial impact of the pandemic on our results of operations, we initially implemented temporary cost-cutting initiatives to better align our cost structure with the expected decline in 2020 sales. Effective July 1, 2020, we reinstated employee salaries, which had been reduced as one of the temporary measures taken in April and most employees have returned from temporary furloughs; however, we continued the postponement of most 2020 merit increases and suspension of matching contributions for the U.S. 40l(k) plan during the third quarter. Likewise, actions to reduce discretionary spending and delay hiring and non-essential capital spending remain in effect and we continue to manage the number of employees working in our manufacturing and distribution facilities based upon demand. Finally, we have turned our attention to more permanent structural changes that are necessary in light of the anticipated longer-term impacts of COVID-19 on our business. Our worldwide headcount is down approximately 700 people, or 10 percent, compared with year end 2019. These cost reduction actions, when combined with our normal productivity savings, reduced costs approximately $20 million for the third quarter. We continue to evaluate the impact of COVID-19 on our business and expect to make additional structural changes and take associated restructuring charges in future quarters.

Where we qualify, we have taken full advantage of government assistance available to employers in the countries outside the U.S. where we operate. Most of this assistance is designed to encourage and enable companies to sustain employment, including pay and working conditions of employees, by providing cash benefits to employers. In the third quarter, we received $3.5 million in government assistance to offset the payroll and other costs of retaining our employees. This assistance was

32

accounted for on a cash-received basis and, therefore, our third quarter includes government assistance we qualified for based on our second quarter results. As the pandemic appears to be abating in some regions, these government assistance programs are being reduced or eliminated and there can be no assurance that government assistance programs will continue or that we will continue to meet the performance criteria to obtain benefits.

There can be no assurance that these cost-savings measures, and any additional cost-savings measures we may implement in the future, will be sufficient to offset the current and future adverse financial impacts of COVID-19 on our business, results of operation or financial condition.

Liquidity, Capital Resources and Other Assets

We are in a strong financial position with $85.8 million cash on hand and $465.5 million available for borrowings under our $600 million committed revolving credit facility as of the end of the third quarter. During the second quarter of 2020, we amended our bank debt maintenance covenant increasing the maximum consolidated leverage ratio from 3.75x to 4.75x, stepping back down to 3.75x for the first quarter ending after June 30, 2021. This provides us with additional financial flexibility to cover the anticipated financial impact of COVID-19 should we need it. As of September 30, 2020, our consolidated leverage ratio was 3.45x. We have no debt maturities before May 2024.

Early in 2020, we announced that we do not intend to repurchase additional shares of our common stock during 2020. Our long-term strategy remains to deploy cash to fund dividends, reduce debt, make acquisitions and repurchase stock.

We are monitoring our working capital, including accounts receivable and inventory. We have and are continuing to experience an increased level of late payments and potential bad debts in certain geographies as our customers deal with the COVID-19 impacts on their businesses. Our bad debt expense was $2.6 million higher in the current quarter than in the third quarter of 2019 and $6.3 million higher on a year-to-date basis than the prior year. We are actively managing our receivables and have restricted and will continue to restrict our own sales if necessary to mitigate our risk. In addition, the drop in demand has increased the need to make additional provisions for slow moving inventory. In the third quarter, we had a $5.7 million charge for inventory provisions, $0.5 million higher than the third quarter of 2019 and $4.8 million higher on a year-to-date basis than the prior year. We anticipate that these trends for increased bad debt and inventory provisions will continue.

We continue to monitor the significant global impact and uncertainty as a result of COVID-19 to assess the outlook for demand for our products and the effect on our business and our overall financial performance. Although the full impact of COVID-19 on demand remains uncertain, with impact varying significantly by geographic region, we remain committed to taking the actions necessary to protect our long-term financial performance expectations and position the Company for long-term growth. We expect the macroeconomic environment will recover in the medium to long-term. Given our financial strength, we currently expect to be able to maintain adequate liquidity as we manage through the current environment.

Outlook

For the fourth quarter, we expect the business impacts from COVID-19 will continue to vary significantly by geographic region and country depending upon a range of factors, including how seriously the pandemic is affecting public health in the country and whether and to what degree businesses and schools are open, the general seasonality of our business in that country, the nature and level of government support, and the channel structure. By way of example, our New Zealand and Asia businesses are currently experiencing a lower impact from the pandemic. However, many parts of Europe are currently experiencing a second wave. Likewise, we expect our Latin American businesses to continue to be significantly and adversely impacted by COVID-19 during the fourth quarter and the early part of 2021.

While the level of overall orders improved across all of our segments during the third quarter versus the second quarter, there can be no assurance that this will continue, or that orders will not decline in the future. We have limited visibility for the fourth quarter and even less into 2021, but we expect overall demand to continue to be down relative to 2019, especially for commercial products and for back-to-school products in Brazil. For North America, commercial products represent a larger share of sales mix, and EMEA has historically also seen very strong commercial sales in the fourth quarter. There is great uncertainty as to how the recent increases in COVID-19 cases will impact potential sales outcomes for the balance of 2020 and beyond.

We expect that the pandemic will continue to materially and adversely affect our business, sales, and results of operations for some time, but we cannot reasonably estimate its financial impact beyond the fourth quarter at this time. We are also uncertain as to the magnitude of the longer-term impact on our results of operations, financial condition, liquidity, customers, consumers, suppliers, industry and employees. Even after the pandemic has subsided, we may experience materially adverse

33

impacts on our business due to any resulting economic recession or depression, a change in the competitive landscape or changes in the behavior of customers, consumers and other end users.

Acquisitions

Indústria Gráfica Foroni Ltda. Acquisition

Effective August 1, 2019, we completed the acquisition (the "Foroni Acquisition") of Indústria Gráfica Foroni Ltda. ("Foroni"), a leading provider of Foroni® branded notebooks and paper-based school and office products in Brazil. The purchase price was $41.5 million inclusive of working capital adjustments. We also assumed $7.6 million of debt. The Foroni Acquisition advanced our strategy to expand in faster growing geographies and product categories, add consumer-centric brands and diversify our customer base. The results of Foroni are included in the ACCO Brands International segment effective August 1, 2019.

For further information on the Foroni Acquisition, see "Note 3. Acquisitions" to the condensed consolidated financial statements contained in Item 1. of this Quarterly Report on Form 10-Q.

Foreign Exchange Rates

The quarterly and year-to-date average foreign exchange rates for the currencies in most of our major markets have declined relative to the U.S. dollar from the prior-year-to-date period, although many currencies strengthened versus the U.S. dollar during the third quarter as detailed below:

	2020 3rd QTR Average Versus 2019 3rd QTR Average	2020 YTD Average Versus 2019 YTD Average
Currency	Increase/(Decline)	Increase/(Decline)
Euro	5%	—%

Net Sales

For the three months ended September 30, 2020, net sales decreased primarily due to the COVID-19 impacts. While these impacts were overall less severe than in the second quarter, our International segment experienced the most significant impact. The impact in our North America segment was more modest and even smaller in our EMEA segment. Adverse foreign exchange contributed $0.5 million, or 0.1 percent, to the decline. Net sales benefited from the Foroni Acquisition with the additional one month contributing $1.0 million to net sales. Back-to-school sales in North America and Mexico declined because of low replenishment orders. Our commercial office product sales continued to exhibit the largest decline from COVID-19 impacts, partially offset by growth in Kensington® computer accessories, TruSens® air purifiers, Leitz® shredders, and Derwent® art supplies.

For the nine months ended September 30, 2020, net sales decreased primarily due to lower demand resulting from COVID-19 impacts in all three segments. Adverse foreign exchange was $18.1 million, or 1.3 percent. Net sales benefited from the Foroni Acquisition with the additional seven months contributing $16.7 million.

Cost of Products Sold

Cost of products sold includes all manufacturing, product sourcing and distribution costs, including depreciation related to assets used in manufacturing; procurement and distribution process; allocation of certain information technology costs supporting those processes; inbound and outbound freight; shipping and handling costs; purchasing costs associated with materials and packaging used in the production processes; and inventory valuation adjustments.

For the three months ended September 30, 2020, foreign exchange reduced cost of products sold $0.8 million, or 0.2 percent, and the Foroni Acquisition added $1.0 million, or 0.3 percent. Excluding Foroni and foreign exchange, cost of products sold decreased primarily due to lower comparable net sales. Additional factors included cost reductions, partially offset by lower fixed cost absorption. We received $1.5 million in government assistance, primarily provided in return for maintaining employment and wages.

For the nine months ended September 30, 2020, foreign exchange reduced cost of products sold $13.6 million, or 1.4

35

percent, and the Foroni Acquisition added $15.7 million, or 1.6 percent. Excluding Foroni and foreign exchange, cost of products sold decreased, primarily due to lower comparable sales. Additional factors included cost reductions, partially offset by lower fixed cost absorption, and $4.8 million of additional reserves for slow moving and obsolete inventory. We received $3.0 million in government assistance, primarily provided in return for maintaining employment and wages.

Gross Profit

We believe that gross profit and gross profit margin provide enhanced shareholder understanding of our underlying operating profit drivers.

For the three months ended September 30, 2020, foreign exchange increased gross profit $0.3 million, or 0.2 percent. Excluding foreign exchange, gross profit decreased primarily due to lower comparable sales.

For the three months ended September 30, 2020, gross profit as a percent of net sales decreased 220 basis points. Gross profit margin declined in the North America and International segments primarily due to an unfavorable customer and product mix, and lower fixed cost absorption.

For the nine months ended September 30, 2020, foreign exchange reduced gross profit $4.5 million, or 1.0 percent, and the Foroni Acquisition added $1.0 million, or 0.2 percent. Excluding Foroni and foreign exchange, gross profit decreased primarily due to lower comparable sales.

For the nine months ended September 30, 2020, gross profit as a percent of net sales decreased 240 basis points. Gross profit margin declined in all segments, primarily due to an unfavorable customer and product mix, lower fixed cost absorption, and higher charges for slow moving and obsolete inventory.

Selling, General and Administrative Expenses

Selling, 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 expenses outside the manufacturing and distribution functions (e.g., finance, human resources, and information technology).

For the three months ended September 30, 2020, foreign exchange reduced SG&A $0.7 million, or 0.7 percent, and the Foroni Acquisition added $0.3 million, or 0.3 percent. The current year includes $0.1 million of integration costs related to the Foroni Acquisition. Excluding Foroni, integration costs, and foreign exchange, SG&A declined due to cost reductions, partially offset by an accrual for pay restitutions to our employees and $2.6 million of increased bad debt expense. SG&A benefited from $2.0 million in government assistance, primarily provided in return for maintaining employment and wages.

For the three months ended September 30, 2020, SG&A as a percentage of net sales increased, primarily due to lower net sales, partially offset by lower SG&A expense.

For the nine months ended September 30, 2020, foreign exchange reduced SG&A $5.0 million, or 1.7 percent, and the Foroni Acquisition added $3.2 million, or 1.1 percent. The current-year period includes $0.8 million of integration and transaction costs related to the Foroni Acquisition. The prior-year period included $1.9 million in integration costs related to prior acquisitions. Excluding Foroni, integration and transaction costs, and foreign exchange, SG&A declined due to cost reductions, partially offset by $6.3 million of increased bad debt expense. SG&A benefited from $4.5 million in government assistance, primarily provided in return for maintaining employment and wages.

For the nine months ended September 30, 2020, SG&A as a percentage of net sales increased, primarily due to lower net sales.

Restructuring Charges

For the three months ended September 30, 2020, restructuring charges were $0.5 million for severance expense in North America and International.

36

For the nine months ended September 30, 2020, restructuring charges were $7.3 million. Costs associated with severance expense in North America were $5.0 million. The remainder of the severance charges were in Mexico, Brazil, EMEA and Australia. The prior-year charges related to severance costs associated with changes in the operating structure of our North America and International segments.

Operating Income

For the three months ended September 30, 2020, operating income decreased, primarily due to lower net sales from COVID-19 impacts, which were partially offset by cost reductions. Foreign exchange benefited operating income $1.0 million, or 2.0 percent. Foroni contributed a loss of $1.5 million.

For the nine months ended September 30, 2020, operating income decreased, primarily due to lower net sales from COVID-19 impacts, which were partially offset by cost reductions. Foreign exchange benefited operating income $1.0 million, or 0.8 percent. Foroni contributed a loss of $3.9 million.

Interest Expense and Income

For both the three and nine months ended September 30, 2020, the decrease in interest expense was primarily due to lower average debt outstanding and lower interest rates on our variable rate debt. The decrease in interest income was primarily due to lower cash balances being held in Brazil.

Income Tax Expense

For the three months ended September 30, 2020, the decrease in the effective tax rate in 2020 was primarily driven by an accrual made in the prior year of $1.6 million of Brazilian income taxes on a contingent gain.

For the nine months ended September 30, 2020, the decrease in effective tax rate for the period was primarily due to an increase in reserves for uncertain tax positions in the prior year, Brazilian income taxes accrued on a contingent gain and a decrease in non-deductible interest in the current year.

For the nine months ended September 30, 2019, the high effective tax rate for the prior-year period was primarily due to the Company increasing its reserves for uncertain tax positions in connection with the Brazil Tax Assessments (see Brazil Tax Assessments below) in the amount of $5.6 million, the accrual of the previously mentioned $1.6 million of Brazilian income taxes on a contingent gain, and the recording of deferred state taxes on unremitted non-U.S. earnings in the amount of $0.8 million and other reserves related to various tax contingencies.

See "Note 11. Income Taxes - Brazil Tax Assessments" to the condensed consolidated financial statements contained in Item 1. of this report for additional details on the Brazil Tax Assessments.

Net Income/Diluted Income per Share

For the three months ended September 30, 2020, net income decreased primarily due to lower operating income. Foreign exchange increased net income $0.9 million, or 3.2 percent. Diluted income per share benefited from fewer outstanding shares.

For the nine months ended September 30, 2019, net income decreased primarily due to lower operating income. Foreign exchange increased net income $0.9 million, or 1.4 percent. Diluted income per share benefited from fewer outstanding shares.

For the three months ended September 30, 2020, net sales decreased primarily from lower demand due to COVID-19 impacts. The segment saw very strong growth in sales of Kensington® computer accessories, which included its largest ever single contract shipment, more than doubling its sales in the quarter from last year. Sales of TruSens® air purifiers and Derwent® art supplies also posted good growth. This was offset by a weak back-to-school sell-out as approximately 70 percent of students were partly or fully learning remotely, which caused customers and consumers to reduce purchases. We expect an elongated back-to-school season that will extend into the fourth quarter, as retailers continue to sell through a larger-than-normal inventory overhang. Excluding the growth in computer accessories, we continue to experience more significant sales reductions with our commercial and office superstore customers, and we expect this trend to continue. Sales to these customers collectively were down approximately 30 percent compared with the prior year while our sales to mass/retail/e-tail customers, which are heavily weighted to back to school, were only down approximately 11 percent relative to the prior year. Unfavorable foreign exchange reduced net sales $0.5 million, or 0.2 percent.

For the nine months ended September 30, 2020, net sales decreased primarily from lower demand due to COVID-19 impacts. The segment saw very good growth in Kensington® and TruSens® branded products. Back-to-school sales for the second and third quarters combined were approximately 5 percent below 2019 primarily due to a reduction in the total back-to-school market. In addition, we reduced both our sales of private label products and sales to certain retailers. We have experienced the more severe COVID-19 impacts in our commercial product lines while sales to mass/retail/e-tail customers remained flat. Unfavorable foreign exchange reduced net sales $1.3 million, or 0.2 percent.

For the three months ended September 30, 2020, operating income and operating margin decreased primarily due to lower sales related to COVID-19 impacts and unfavorable customer and product mix. Partially offsetting these factors were cost reductions and $0.4 million in Canadian government assistance, primarily provided in return for maintaining employment and wages.

For the nine months ended September 30, 2020, operating income and operating margin decreased primarily due to lower sales related to COVID-19 impacts, unfavorable customer and product mix, lower fixed cost absorption and increased reserves for slow moving and obsolete inventory. Restructuring charges were $5.3 million versus $1.5 million in the prior year. Partially offsetting these factors were cost reductions, and $1.6 million in Canadian government assistance, primarily provided in return for maintaining employment and wages.

For the three months ended September 30, 2020, net sales increased due to favorable foreign exchange of $6.1 million, or 4.6 percent. Comparable sales declined 2.1 percent primarily from lower demand related to COVID-19 impacts. These impacts were largely offset by growth in sales of Leitz® personal shredders, TruSens® air purifiers, DIY tools, and computer accessories. EMEA experienced a much stronger level of demand in the third quarter compared with the second quarter as many COVID-19 restrictions were lifted and commercial businesses and consumers were less adversely impacted. Given the recent resurgence of the COVID-19 pandemic throughout Europe, there can be no assurance this demand will continue in the fourth quarter.

For the nine months ended September 30, 2020, net sales and comparable sales decreased primarily from lower demand due to COVID-19 impacts. Unfavorable foreign exchange reduced net sales $0.3 million, or 0.1 percent.

For the three months ended September 30, 2020, operating income and margin improved primarily from a higher gross margin (50 basis points) and lower SG&A costs (100 basis points), as well as $0.3 million of lower restructuring charges. EMEA received $1.2 million in governments' assistance, primarily provided in return for maintaining employment and wages. Foreign exchange increased operating income $0.7 million, or 5.1 percent.

For the nine months ended September 30, 2020, operating income and operating margin declined primarily due to lower sales from COVID-19 impacts, lower fixed cost absorption, and higher bad debt expense. Partially offsetting these factors were cost reductions and $2.7 million in governments' assistance, primarily provided in return for maintaining employment and wages. Foreign exchange increased operating income $0.6 million, or 1.6 percent.

For the three months ended September 30, 2020, net sales decreased primarily as a result of lower demand due to COVID-19 impacts, which were felt in all markets, but most severely in Mexico, Brazil, and Chile (representing 70 percent of the segment decline). Outside of Latin America, the largest impact on demand was from the lockdown in the state of Victoria, Australia. Net sales benefited from the Foroni Acquisition with the additional one month contributing $1.0 million to net sales. Unfavorable foreign exchange was $6.1 million, or 6.1 percent. Excluding Foroni and foreign exchange, comparable sales decreased $25.9 million, or 25.8 percent, primarily due to lower demand from COVID-19 impacts.

For the nine months ended September 30, 2020, net sales and comparable sales decreased primarily as a result of lower demand related to COVID-19 impacts. Net sales benefited from the Foroni Acquisition with the additional seven months contributing $16.7 million, or 6.2 percent, which was largely offset by unfavorable foreign exchange of $16.5 million, or 6.1 percent.

For the three months ended September 30, 2020, foreign exchange increased operating income $0.3 million, or 2.8 percent. Operating income included a $1.5 million loss from Foroni. Excluding Foroni and foreign exchange, the decrease in operating income was primarily driven by lower sales, adverse customer and product mix, higher bad debt expense, and lower

39

fixed cost absorption. Partially offsetting these factors were cost reductions and $1.9 million in government assistance, primarily provided in return for maintaining employment and wages. Restructuring charges in the quarter were $0.3 million versus $0.1 million in the prior year.

For the nine months ended September 30, 2020, foreign exchange increased operating income $0.6 million, or 2.9 percent. Foroni contributed a loss of $3.9 million. Excluding Foroni and foreign exchange, operating income decreased primarily from lower sales, lower fixed cost absorption and higher bad debt expense. Partially offsetting these factors were cost reductions and $3.2 million in government assistance, primarily provided in return for maintaining employment and wages. Restructuring charges were $1.5 million versus $1.2 million in the prior year.

Supplemental Non-GAAP Financial Measure

To supplement our condensed consolidated financial statements presented in accordance with generally accepted accounting principles in the U.S. ("GAAP"), we provide investors with certain non-GAAP financial measures, including comparable net sales. Comparable net sales represent net sales excluding the impact of acquisitions and with current-period foreign operation sales translated at prior-year currency rates. We sometimes refer to comparable net sales as comparable sales.

We use comparable net sales both to explain our results to stockholders and the investment community and in the internal evaluation and management of our business. We believe comparable net sales provide management and investors with a more complete understanding of our underlying operational results and trends, facilitate meaningful period-to-period comparisons and enhance an overall understanding of our past and future financial performance. Comparable net sales should not be considered in isolation or as a substitute for, or superior to, the directly comparable GAAP financial measure and should be read in connection with the Company's financial statements presented in accordance with GAAP.

The following tables provide a reconciliation of GAAP net sales change as reported to non-GAAP comparable net sales change:

Liquidity and Capital Resources

Our primary liquidity needs are to service indebtedness, fund capital expenditures, fund our acquisition strategy and support working capital requirements. Our principal sources of liquidity are cash flows from operating activities, cash and cash equivalents held and seasonal borrowings under our $600 million multi-currency revolving credit facility (the "Revolving Facility"). As of September 30, 2020, there was $123.7 million in borrowings outstanding under the Revolving Facility ($5.2 million reported in "Current portion of long-term debt" and $118.5 million reported in "Long-term debt, net") and the amount available for borrowings was $465.5 million (allowing for $10.8 million of letters of credit outstanding on that date). We maintain adequate financing arrangements at market rates.

We are in a strong financial position with $85.8 million cash on hand and $465.5 million available for borrowings under our Revolving Facility as of the end of the third quarter of 2020. During the second quarter, we amended our bank debt maintenance covenant increasing the maximum consolidated leverage ratio from 3.75x to 4.75x, stepping back down to 3.75x for the first quarter ending after June 30, 2021. This will provide us additional financial flexibility to cover the anticipated financial impact of COVID-19 should we need it. As of September 30, 2020, our consolidated leverage ratio was 3.45x. We have no debt maturities before May 2024.

Early in 2020, we announced that we do not intend to repurchase additional shares of our common stock during 2020. Our long-term strategy remains to deploy cash to fund dividends, reduce debt, make acquisitions and repurchase stock.

We are monitoring our working capital, including accounts receivable and inventory. We have and are continuing to experience an increased level of late payments and potential bad debts in certain geographies as our customers deal with the COVID-19 impacts on their businesses. Our bad debt expense was $2.6 million higher in the current quarter than in the third quarter of 2019 and $6.3 million higher on a year-to-date basis than the prior year. We are actively managing our receivables and have restricted and will continue to restrict our own sales if necessary to mitigate our risk. In addition, the drop in demand

41

has increased the need to make additional provisions for slow moving inventory. In the third quarter, we had a $5.7 million charge for inventory provisions, $0.5 million higher than the third quarter of 2019 and $4.8 million higher on a year-to-date basis than the prior year. We anticipate that these trends for increased bad debt and inventory provisions will continue.

The $536.5 million of debt currently outstanding under our senior secured credit facilities has a weighted average interest rate of 2.41 percent as of September 30, 2020, and the $375.0 million outstanding principal amount of our senior unsecured notes (the "Senior Unsecured Notes") has a fixed interest rate of 5.25 percent.

Consolidated cash and cash equivalents were $85.8 million as of September 30, 2020, approximately $23 million of which was held in Brazil. Our Brazilian businesses is highly seasonal due to the timing of the back-to-school season, which coincides with the calendar year-end in the fourth quarter. Due to various tax laws, it is costly to make frequent cash transfers in and out of Brazil; therefore, our normal practice is to hold seasonal cash requirements in Brazil, and invest it in short-term Brazilian government securities.

Adequacy of Liquidity Sources

We believe that cash flow from operations, our current cash balance and other sources of liquidity, including borrowings available under our Revolving Facility, will be adequate to support our requirements for working capital, capital and restructuring expenditures and to service indebtedness for the foreseeable future.

Restructuring and Integration Activities

From time to time the Company may implement restructuring, realignment or cost-reduction plans and activities, including those related to integrating acquired businesses.

During the three and nine months ended September 30, 2020, the Company recorded $0.5 million and $7.3 million, respectively, in restructuring expenses primarily related to costs associated with cost reduction programs initiated during the second quarter of 2020, representing expected severance costs in North America. Additional severance charges were also taken in Mexico, Brazil, EMEA and Australia. For additional details, see "Note 10. Restructuring" to the condensed consolidated financial statements contained in "Part I, Item 1. Financial Information" of this Quarterly Report on Form 10-Q.

In addition, during the three and nine months ended September 30, 2020, the Company recorded an aggregate $0.1 million and $0.8 million, respectively, in non-restructuring integration expenses related to the integration of Foroni with ACCO Brands' operations in Brazil.

Cash Flow for the Nine Months Ended September 30, 2020 and 2019

Cash Flow from Operating Activities

Cash provided by operating activities during the nine months ended September 30, 2020 was $21.8 million, a reduction of $53.3 million compared to cash provided by operating activities of $75.1 million during the nine months ended September 30, 2019. The reduction of $53.3 million included reduced net income of $31.1 million, an $18.2 million of additional cash used for paying accrued expenses, including income taxes, and an increase in cash used for working capital requirements of $3.5 million.

The table below shows our cash flow used or provided by accounts receivable, inventories and accounts payable for the nine months ended September 30, 2020 and 2019:

	Nine Months Ended				Amount of Change
(in millions)	September 30, 2020		September 30, 2019
Accounts receivable	$	78.7	$	54.0	$	24.7
Inventories	(28.4)		34.8		(63.2)
Accounts payable	(67.1)		(102.1)		35.0
Cash flow used by net working capital	$	(16.8)	$	(13.3)	$	(3.5)

42

•Accounts receivable was a source of cash of $78.7 million during the nine months ended September 30, 2020, a favorable change of $24.7 million compared to a source of cash of $54.0 million during the first nine months ended September 30, 2019. The $24.7 million improvement included an increase in cash collections in early 2020, compared to early 2019, due to a receivable balance at the end of 2019 that was $25.3 million higher than 2018.

•Inventories was a use of cash of $28.4 million during the nine months ended September 30, 2020, an unfavorable change of $63.2 million when compared with the $34.8 million cash provided during the nine months ended September 30, 2019. The use of cash for inventory was higher during the nine months ended September 30, 2020, compared to the nine months ended September 30, 2019, as a result of the Company acquiring less inventory during the first nine months of 2019. This was due to the Company acquiring inventory during the fourth quarter of 2018 that would normally be acquired during 2019 in order to secure supply and to partially reduce anticipated inflation and import tariffs that went into effect during 2019.

•Accounts payable was a use of cash of $67.1 million during the nine months ended September 30, 2020, a favorable change of $35.0 million when compared to a use of cash of $102.1 million during the nine months ended September 30, 2019. The use of cash for accounts payable was higher during the nine months ended September 30, 2019 as a result of the Company paying for the additional inventory that was acquired during the fourth quarter of 2018.

Cash Flow from Investing Activities

Cash used by investing activities was $11.2 million and $69.1 million for the nine months ended September 30, 2020 and 2019, respectively. Cash used for capital expenditures was down $10.1 million primarily due to the completion of certain IT projects completed during 2020. Cash used for acquisitions was $47.3 million in 2019 which included the Foroni acquisition for $42.1 million and the acquisition of certain assets of the Cumberland brand in Australia for $5.2 million.

Cash Flow from Financing Activities

Cash provided by financing activities was $48.6 million for the nine months ended September 30, 2020, an increase of $82.7 million, compared with cash used of $34.1 million by financing activities during the first nine months of the prior year. The increase of $82.7 million primarily relates to a reduction of cash used for share repurchases of $37.9 million and an increase in cash provided by our incremental net borrowings of $42.3 million during the first nine months of 2020, compared to the prior year’s first nine months.

Credit Facilities and Notes Covenants

As of and for the periods ended September 30, 2020 and December 31, 2019, the Company was in compliance with all applicable loan covenants.

Guarantees and Security

Generally, obligations under the Credit Agreement are guaranteed by certain of the Company’s existing and future subsidiaries, and are secured by substantially all of the Company’s and certain guarantor subsidiaries’ assets, subject to certain exclusions and limitations.

PART II — OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

There are various claims, lawsuits and pending actions against us incidental to our operations, including the income tax assessments against our Brazilian subsidiary, Tilibra Produtos de Papelaria Ltda (the "Brazil Tax Assessments"), which is more fully described in our Annual Report on Form 10-K for the year ended December 31, 2019 and in "Part I, Item 1. Note 11. Income Taxes - Brazil Tax Assessments" to the Condensed Consolidated Financial Statements contained in this Quarterly Report on Form 10-Q.

It is the opinion of management that (other than the Brazil Tax Assessments) the ultimate resolution of currently outstanding matters will 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 be successful in our 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.

ITEM 1A. RISK FACTORS

There have been no material changes in our risk factors from those disclosed "Part I, Item 1A. Risk Factors" in our Annual Report on Form 10-K for the year ended December 31, 2019, except as updated under "Part II, Item 1A.

Basis Of Presentation

1. Basis of Presentation

As used in this Quarterly Report on Form 10-Q for the quarter ended September 30, 2020, 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 Corporation is responsible for the accuracy and internal consistency of the preparation of the condensed consolidated financial statements and notes contained in this Quarterly Report on Form 10-Q.

The condensed consolidated interim 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 generally accepted accounting principles in the 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, 2019.

The Condensed Consolidated Balance Sheet as of September 30, 2020, the related Consolidated Statements of Income, the Consolidated Statements of Comprehensive Income (Loss), and the Consolidated Statement of Stockholders' Equity for the three and nine months ended September 30, 2020 and 2019 and Condensed Consolidated Statements of Cash Flows for the nine months ended September 30, 2020 and 2019 are unaudited. The December 31, 2019 Condensed Consolidated Balance Sheet data was derived from audited financial statements, but does not include all annual disclosures required by GAAP. The above referenced financial statements included herein were prepared by management 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, 2020 and 2019, and the financial position of the Company as of September 30, 2020. Interim results may not be indicative of results for a full year.

Effective August 1, 2019, we completed the acquisition (the "Foroni Acquisition") of Indústria Gráfica Foroni Ltda. ("Foroni"), a leading provider of Foroni® branded notebooks and paper-based school and office products in Brazil. The purchase price was $41.5 million inclusive of working capital adjustments. The Foroni Acquisition advanced our strategy to expand in faster growing geographies and product categories, add consumer-centric brands and diversify our customer base. The results of Foroni are included in the ACCO Brands International segment effective August 1, 2019. See "Note 3. Acquisitions" for details on the Foroni Acquisition.

The preparation of financial statements in conformity with 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.

Recent Accounting Pronouncements

2. Recent Accounting Pronouncements and Adopted Accounting Standards

Recent Accounting Pronouncements

In December 2019, the Financial Accounting Standards Board ("FASB") issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which removes certain exceptions for investments, intraperiod allocations and interim calculations, and adds guidance to reduce complexity in accounting for income taxes. ASU 2019-12 is effective for annual periods, and interim periods within those years, beginning after December 15, 2020. The Company is currently evaluating the effects the standard will have on its consolidated financial statements.

There are no other recently issued accounting standards that are expected to have an impact on the Company’s financial condition, results of operations or cash flow.

Recently Adopted Accounting Standards

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, an accounting standard that requires companies to utilize an impairment model (current expected credit loss, or "CECL") for most financial assets measured at amortized cost and certain other financial instruments, which include, but are not limited to, trade and other receivables. This accounting standard replaced the incurred loss model

with a model that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to estimate those losses. Effective January 1, 2020, the Company adopted this standard. The adoption of this standard did not have a material impact on our condensed consolidated financial statements.

There were no other accounting standards that were adopted in the first nine months of 2020 that had a material effect on the Company’s financial condition, results of operations or cash flow.

3. Acquisitions

Acquisition of Foroni

Effective August 1, 2019, we completed the acquisition of Foroni, a leading provider of Foroni® branded notebooks and paper-based school and office products in Brazil. The Foroni Acquisition advanced our strategy to expand in faster growing geographies and product categories, add consumer-centric brands and diversify our customer base. The results of Foroni are included in the ACCO Brands International segment effective August 1, 2019.

The purchase price was R$157.2 million (US$41.5 million based on July 31, 2019, exchange rates) inclusive of working capital adjustments. We also assumed $7.6 million in debt. A portion of the purchase price (R$25.0 million or US$6.6 million based on July 31, 2019 exchange rates) is being held in an escrow account for a period of up to 6 years after closing in the event of any claims against the sellers under the quota purchase agreement. The Company may also make claims against the sellers directly, subject to limitations in the quota purchase agreement, if the escrow is depleted. The Foroni Acquisition and related expenses were funded by cash on hand.

For accounting purposes, the Company was the acquiring enterprise. The Foroni Acquisition is being accounted for as a purchase business combination and Foroni's results are included in the Company’s condensed consolidated financial statements as of August 1, 2019. The additional net sales from Foroni for the one and seven months ended July 31, 2020 were $1.0 million and $16.7 million, respectively.

The following table presents the allocation of the consideration given to the fair values of the assets acquired and liabilities assumed at the date of acquisition, which was finalized in the third quarter of 2020:

(in millions)	At August 1, 2019
Calculation of Goodwill:
Purchase price, net of working capital adjustment	$	41.5
Plus fair value of liabilities assumed:
Accounts payable and accrued liabilities	13.9
Deferred tax liabilities	5.4
Debt	7.6
Lease liabilities	5.3
Other non-current liabilities	1.5
Fair value of liabilities assumed	$	33.7
Less fair value of assets acquired:
Cash acquired	—
Accounts receivable	17.5
Inventory	12.5
Property and equipment	8.8
Identifiable intangibles	11.1
Deferred tax assets	2.7
Right of use asset, leases	5.3
Other assets	3.6
Fair value of assets acquired	$	61.5
Goodwill	$	13.7

During the year ended December 31, 2019, transaction costs related to the Foroni Acquisition were $1.5 million, and for the nine months ended September 30, 2020, they were $0.2 million. These costs were reported as selling, general and administrative ("SG&A") expenses in the Company's Consolidated Statements of Income.

The Company entered into a Third Amended and Restated Credit Agreement (the "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 agents and various lenders party thereto. The Credit Agreement provided for a five-year senior secured credit facility, which consisted of a €300.0 million (US$320.8 million based on January 27, 2017, exchange rates) term loan facility, an A$80.0 million (US$60.4 million based on January 27, 2017, exchange rates) term loan facility, and a US$400.0 million multi-currency revolving credit facility (the "Revolving Facility").

Effective July 26, 2018, the Company entered into the First Amendment (the "First Amendment") to the Credit Agreement among the Company, certain subsidiaries of the Company, Bank of America, N.A., as administrative agent, and the other lenders party thereto. The First Amendment increased the aggregate revolving credit commitments under the Revolving Facility by $100.0 million such that, after giving effect to such increase, the aggregate amount of revolving credit available under the Revolving Facility was $500.0 million. In addition, the First Amendment also affected certain technical amendments to the Credit Agreement, including the addition of provisions relating to LIBOR successor rate procedures if LIBOR becomes unascertainable or is discontinued in the future and to expressly permit certain intercompany asset transfers. The changes related to LIBOR successor rate procedures are not expected to have a material effect on the Company.

Effective May 23, 2019, the Company entered into a Second Amendment (the "Second Amendment") to the Credit Agreement. Pursuant to the Second Amendment, the Credit Agreement was amended to, among other things:

•extend the maturity date to May 23, 2024;

•increase the aggregate revolving credit commitments under the Revolving Facility from $500.0 million to $600.0 million;

•establish a new term loan facility denominated in U.S. Dollars in an aggregate principal amount of $100.0 million (the "USD Term Loan");

•replace the minimum fixed coverage ratio of 1.25:1.00 with a minimum interest coverage ratio, as calculated under the Credit Agreement, of 3.00:1.00;

•reflect a more favorable restricted payment covenant, with the consolidated leverage ratio hurdle for unlimited restricted payments (including share repurchases and dividends) as calculated under the Credit Agreement increasing from 2.50:1.00 to 3.25:1.00;

•reflect, in certain cases, more favorable pricing with a 25-basis point reduction in the applicable rate on outstanding loans than was in effect prior to the Second Amendment based on the Company's current consolidated leverage ratio, along with lower fees on undrawn amounts;

•eliminate the requirement to make annual principal prepayments of excess cash flow;

•reduce amortization payments for the term loans; and

•increase the qualified receivables transaction basket with respect to sales or financings of certain receivables.

Effective upon the closing of the Second Amendment, the Company borrowed the entire principal amount committed under the USD Term Loan, which was used to repay revolver borrowings and, in combination with the increase in the Revolving Facility, resulted in $200.0 million of additional liquidity becoming available under the Revolving Facility.

On May 1, 2020, the Company entered into a Third Amendment (the "Third Amendment") to its Credit Agreement, among the Company, certain subsidiaries of the Company, Bank of America, N.A., as administrative agent, and the other lenders party thereto. Pursuant to the Third Amendment, the Credit Agreement was amended to, among other things:

•increase the maximum consolidated leverage ratio from 3.75:1.00 to 4.75:1.00, stepping back down to 3.75:1.00 for the first fiscal quarter ending after June 30, 2021;

•amend the pricing based on the Company’s consolidated leverage ratio, with a scaled increase in fees as follows, effective May 1, 2020:

Leverage Ratio	Applicable Rate	Undrawn Fee
> 4.25 to 1.00	2.75%	0.500%
≤ 4.25 to 1.00 and > 4.00 to 1.00	2.50%	0.500%
≤ 4.00 to 1.00 and > 3.50 to 1.00	2.25%	0.375%
≤ 3.50 to 1.00 and > 3.25 to 1.00	2.00%	0.375%
≤ 3.25 to 1.00 and > 3.00 to 1.00	1.75%	0.300%
≤ 3.00 to 1.00 and > 2.00 to 1.00	1.50%	0.250%
≤ 2.00 to 1.00	1.25%	0.200%

Per the terms of the Third Amendment, pricing will be locked at LIBOR plus 2.00% until the Company publishes its financial results for the fiscal quarter ended June 30, 2020;

•Reduce the Company’s capacity to incur certain other indebtedness, and impose additional limitations on certain restricted payments (other than dividends) and permitted acquisitions; and

•Require that the Company pay down any amounts on the Revolving Facility when cash and cash equivalents of the loan parties exceed $100.0 million.

As of September 30, 2020, there were $123.7 million in borrowings outstanding under the Revolving Facility. The remaining amount available for borrowings was $465.5 million (allowing for $10.8 million of letters of credit outstanding on that date).

As of and for the periods ended September 30, 2020 and December 31, 2019, the Company was in compliance with all applicable loan covenants.

Leases [Abstract]

Leases

5. Leases

The Company leases its corporate headquarters, various other facilities for distribution, manufacturing, and offices, as well as vehicles, forklifts and other equipment. The Company determines if an arrangement is a lease at inception. Leases are included in "Right of use asset, leases" ("ROU Assets"), and the current portion of the lease liability is included in "Lease liabilities" and the non-current portion is included in "Long-term lease liabilities" in the Condensed Consolidated Balance Sheet. The Company currently has an immaterial amount of financing leases and leases with terms of more than one month and less than 12 months. ROU Assets and lease liabilities are recognized based on the present value of lease payments over the lease term. Because most of the Company’s leases do not provide an implicit rate of return, the Company uses its incremental collateralized borrowing rate, on a regional basis, in determining the present value of lease payments. The incremental borrowing rate is dependent upon the duration of the lease and has been segmented into three groups of time. All leases within the same region and the same group of time share the same incremental borrowing rate. The Company has lease agreements with lease and non-lease components, which are combined for accounting purposes for all classes of assets except information technology equipment.

The components of lease expense were as follows:

	Three Months Ended September 30,				Nine Months Ended September 30,
(in millions)	2020		2019		2020		2019

Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill And Identifiable Intangibles

9. Goodwill and Identifiable Intangible Assets

Goodwill

We test goodwill for impairment at least annually, during the second quarter, and on an interim basis if an event or circumstance indicates that there is a triggering event that would make it more likely than not that an impairment loss had been incurred.

During the second quarter ended June 30, 2020, we performed a qualitative assessment of impairment for goodwill for each of our three reporting units. We considered events and circumstances that may affect the fair value of each reporting unit to determine whether it is necessary to perform the quantitative impairment test. We focused on events or circumstances that could affect the significant inputs, including, but not limited to, financial performance, such as negative or declining cash flows, a decline in actual or planned revenue or earnings compared with actual and projected results of relevant prior periods, competitive, economic, industry and market considerations, and other factors that have or could impact each of our reporting

units. If we determine that it is more likely than not that the goodwill is impaired, then we would perform a quantitative impairment test.

The results of our qualitative assessment performed during the second quarter ended June 30, 2020, was that there were no triggering events that would make it more likely than not that an impairment loss to our goodwill has been incurred for any of our three reporting units.

Changes in the net carrying amount of goodwill by segment were as follows:

(in millions)	ACCO Brands North America		ACCO Brands EMEA		ACCO Brands International		Total
Balance at December 31, 2019	$	375.6	$	165.7	$	177.3	$	718.6

Balance at September 30, 2020	$	375.6	$	170.9	$	176.9	$	723.4

The goodwill balance is net of $215.1 million of accumulated impairment losses, which occurred prior to December 31, 2016.

Identifiable Intangible Assets

Foroni Acquisition

The valuation of identifiable intangible assets of $11.1 million acquired in the Foroni Acquisition includes an amortizable trade name, "Foroni®," which has been recorded at its estimated fair value. The fair value of the trade name was determined using the relief from royalty method, which is based on the present value of royalty fees derived from projected revenues. The Foroni® trade name is expected to be amortized over 23 years on a straight-line basis.

The gross carrying value and accumulated amortization by class of identifiable intangible assets as of September 30, 2020 and December 31, 2019, was as follows:

	September 30, 2020							December 31, 2019

The Company's intangible amortization expense was $7.9 million and $8.6 million for the three months ended September 30, 2020 and 2019, respectively, and $24.1 million and $26.8 million for the nine months ended September 30, 2020 and 2019, respectively.

Estimated amortization expense for amortizable intangible assets as of September 30, 2020, for the current year and the next five years is as follows:

Estimated amortization expense(2)	$	32.0	$	28.4	$	24.9	$	22.6	$	21.0	$	19.4

(2)    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. We performed this annual assessment, on a qualitative basis, as allowed by GAAP, for our indefinite-lived trade names in the second quarter of 2020 and concluded that no impairment existed.

COVID-19 Impact

We continue to monitor the significant global impact and uncertainty as a result of COVID-19 to assess the outlook for demand for our products and the effect on our business and our overall financial performance. This includes our risk of impairment of our goodwill and indefinite-lived intangible assets. Although the full impact of COVID-19 on demand remains uncertain, with impact varying significantly by geographic region, we remain committed to taking the actions necessary to protect our long-term financial performance expectations and position the Company for long-term growth. We expect the macroeconomic environment will recover in the medium to long-term. As a result of our analysis, and consideration of events and circumstances, we concluded based on the previously conducted annual assessment, on a qualitative basis, no impairment of our goodwill or indefinite-lived intangible assets was triggered as of June 30, 2020.

The implied fair values of all three of our reporting units, more likely than not, exceed their carrying values at September 30, 2020. In addition, we have not identified a triggering event that would cause us to perform a quantitative goodwill impairment analysis. In management’s opinion, the goodwill balance for our ACCO Brands International reporting unit could be at risk for impairment if operating performance does not recover as expected from the current impacts of COVID-19, if we experience negative changes to the long-term outlook for the business, or changes in factors and assumptions which impact the fair value of our reporting units such as low or declining revenue growth rates, depressed operating margins or adverse changes to the discount rates impacting this report unit.

Income Taxes

11. Income Taxes

For the three months ended September 30, 2020, we recorded an income tax expense of $6.8 million on income before taxes of $25.6 million, for an effective rate of 26.6 percent. The decrease in the effective rate versus the three months ended September 30, 2019 was primarily driven by an accrual made in the prior year of $1.6 million of Brazilian income taxes on a contingent gain.

For the three months ended September 30, 2019, we recorded an income tax expense of $12.2 million on income before taxes of $40.2 million, for an effective rate of 30.3 percent.

For the nine months ended September 30, 2020, we recorded an income tax expense of $13.7 million on income before taxes of $45.9 million, for an effective rate of 29.8 percent. The decrease in the effective rate versus the nine months ended September 30, 2019 was primarily due to an increase in reserves for uncertain tax positions in the prior year, Brazilian income taxes accrued on a contingent gain and a decrease in non-deductible interest in the current year.

For the nine months ended September 30, 2019, we recorded an income tax expense of $38.1 million on income before taxes of $101.4 million, for an effective rate of 37.6 percent. The high effective tax rate for the period was primarily due to the Company increasing its reserves for uncertain tax positions in connection with the Brazil Tax Assessments (see Brazil Tax Assessments below) in the amount of $5.6 million, the accrual of $1.6 million of Brazilian income taxes on a contingent gain, and the recording of deferred state taxes on unremitted non-U.S. earnings in the amount of $0.8 million and other reserves related to various tax contingencies.

The U.S. federal statute of limitations remains open for the years 2016 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 (2016 forward), Brazil (2015 forward), Canada (2016 forward), Germany (2015 forward), Sweden (2015 forward) and the U.K. (2018 forward). We are currently under examination in certain foreign jurisdictions.

Final Section 951A Tax Regulations

On July 20, 2020, the U.S. Department of the Treasury and the Internal Revenue Service issued final section 951A regulations ("Final Regulations") on an election to exclude high-tax global intangible low-taxed income ("GILTI") from a U.S.

shareholder’s gross income. As of the end of the third quarter, we are not expecting that application of the Final Regulations will have a material impact on the Company’s effective tax rate.

Brazil Tax Assessments

In connection with our May 1, 2012, acquisition of the 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 against Tilibra, challenging the tax deduction of goodwill from Tilibra's taxable income for the year 2007 (the "First Assessment"). 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 (the "Second Assessment" and together with the First Assessment, the "Brazil Tax Assessments"). Tilibra is disputing both of the Brazil Tax Assessments.

The final administrative appeal of the Second Assessment was decided against the Company in 2017. In 2018, we decided to appeal this decision to the judicial level. In the event we do not prevail at the judicial level, we will be required to pay an additional penalty representing attorneys' costs and fees; accordingly, in the first quarter of 2019, the Company recorded an additional reserve in the amount of $5.6 million. In connection with the judicial challenge, we were required to provide security to guarantee payment of the Second Assessment should we not prevail.

In the third quarter of 2020, the final administrative appeal of the First Assessment was decided against the Company. We have decided to appeal this decision to the judicial level. We recorded an additional expense in the quarter of $1.2 million representing additional attorneys' costs and fees, which we will be required to pay if we do not prevail at the judicial level.

We believe we have meritorious defenses and intend to vigorously contest both of the Brazil Tax Assessments; however, there can be no assurances that we will ultimately prevail. The ultimate outcome will not be determined until the Brazilian tax appeal process is complete, which is expected to take a number of years. If the FRD's initial position is ultimately sustained, payment of 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 these disputes 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 2007-2012 tax years plus penalties and interest through December 2012. Included in this reserve is an assumption of penalties at 75 percent, which is the standard penalty. While there is a possibility that a penalty of 150 percent could be imposed in connection with the First Assessment, based on the facts in our case and existing precedent, we believe the likelihood of a 150 percent penalty is not more likely than not as of September 30, 2020. We will continue to actively monitor administrative and judicial court decisions and evaluate their impact, if any, on our legal assessment of the ultimate outcome of our disputes. 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. The time limit for issuing an assessment for 2011 and 2012 expired in January 2018 and January 2019, respectively. Since we did not receive an assessments for either of these periods, we reversed the amounts previously accrued, including $5.6 million related to 2011, which was reversed in the first quarter of 2018. During the three months ended September 30, 2020 and 2019, we accrued additional interest as a charge to income tax expense of $0.1 million and $0.3 million, respectively, and for the nine months ended September 30, 2020 and 2019, we accrued additional interest as a charge to current income tax expense of $0.3 million and $0.9 million, respectively. At current exchange rates, our accrual through September 30, 2020, including tax, penalties and interest is $26.1 million (reported in "Other non-current liabilities").

Earnings Per Share [Abstract]

Earnings Per Share

12. Earnings per Share

Total outstanding shares as of September 30, 2020 and 2019, were 94.5 million and 97.2 million, respectively. Under our stock repurchase program, for the three months ended September 30, 2020 no shares were repurchased and for the nine months ended September 30, 2020 we repurchased and retired 2.7 million shares. Under our stock repurchase program, for the three and nine months ended September 30, 2019, we repurchased and retired 2.3 million and 7.0 million shares, respectively. For the nine months ended September 30, 2020 and 2019, we acquired 0.2 million and 0.5 million shares, respectively, related to tax withholding for share-based compensation.

The calculation of basic earnings per share of common stock is based on the weighted-average number of shares of common stock outstanding in the year, or period, over which they were outstanding. Our calculation of diluted earnings per share of common stock assumes that any shares of common stock outstanding were increased by shares that would be issued upon exercise of those stock awards 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.

Our weighted-average shares outstanding for the three and nine months ended September 30, 2020 and 2019 was as follows:

	Three Months Ended September 30,		Nine Months Ended September 30,
(in millions)	2020	2019	2020	2019
Weighted-average number of shares of common stock outstanding - basic	94.5	97.6	95.0	100.4
Stock options	—	0.4	0.1	0.4
Restricted stock units	1.1	0.9	1.1	1.1
Weighted-average shares and assumed conversions - diluted	95.6	98.9	96.2	101.9

Awards of potentially dilutive shares of common stock, 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 and nine months ended September 30, 2020, the number of anti-dilutive shares was approximately 8.0 million and 7.5 million, respectively. For the three and nine months ended September 30, 2019, the number of anti-dilutive shares was approximately 5.0 million and 4.7 million, respectively

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

13. 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 against the U.S. dollar include the Euro, Australian dollar, Canadian dollar, Swedish krona, 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, on the date 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 with third parties 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 (the Euro, the Swedish krona and the British pound), Brazil, Australia, Canada, and Mexico.

Forward currency contracts are used to hedge foreign denominated inventory purchases for Europe, Australia, Canada, Japan and New Zealand, and are designated as cash flow hedges. Unrealized gains and losses on these contracts are deferred in Accumulated Other Comprehensive Income ("AOCI") until the contracts are settled and the underlying hedged transactions relating to inventory purchases are recognized, at which time the deferred gains or losses will be reported in the "Cost of products sold" line in the "Consolidated Statements of Income." As of September 30, 2020 and December 31, 2019, we had cash flow foreign exchange contracts outstanding with a U.S. dollar equivalent notional value of $108.4 million and $96.7 million, respectively, which were designated as hedges.

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 (income), net" in the "Consolidated Statements of Income" 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 May 2024. As of September 30, 2020 and December 31, 2019, we had foreign exchange contracts outstanding with a U.S. dollar equivalent notional value of $171.0 million and $182.6 million, respectively, which were not designated as hedges.

Fair Value Disclosures [Abstract]

Fair Value Of Financial Instruments

14. 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 described in "Note 13. Derivative Financial Instruments" 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, 2020 and December 31, 2019:

(in millions)	September 30, 2020		December 31, 2019
Assets:
Forward currency contracts	$	21.9	$	8.0
Liabilities:
Forward currency contracts	$	22.8	$	9.5

Our forward currency contracts are included in "Other current assets," "Other current liabilities," "Other non-current assets," or "Other non-current liabilities." The forward foreign currency exchange contracts are primarily valued based on the foreign currency spot and forward rates quoted by 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 $917.3 million and $816.0 million and the estimated fair value of total debt was $926.7 million and $831.4 million at September 30, 2020 and December 31, 2019, 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 time to maturity.

Revenue Recognition

Revenue from Contract with Customer [Abstract]

Revenue

16. Revenue Recognition

Revenue is recognized when control of the promised goods or services is transferred to our customers in an amount reflective of the consideration we expect to receive in exchange for those goods or services. Taxes we collect concurrent with revenue producing activities are excluded from revenue. Incidental items incurred that are immaterial in the context of the contract are expensed.

At the inception of each contract, the Company assesses the products and services promised and identifies each distinct performance obligation. To identify the performance obligations, the Company considers all products and services promised regardless of whether they are explicitly stated or implied within the contract or by standard business practices.

Freight and distribution activities performed before the customer obtains control of the goods are not considered promised services under customer contracts and therefore are not distinct performance obligations. The Company has chosen to account for shipping and handling activities as a fulfillment activity, and therefore accrues the expense of freight and distribution in "Cost of products sold" when product is shipped.

Service or Extended Maintenance Agreements ("EMAs"). As of December 31, 2019, there was $5.5 million of unearned revenue associated with outstanding EMAs, primarily reported in "Other current liabilities." During the three and nine months ended September 30, 2020, $0.7 million and $4.8 million of the unearned revenue was earned and recognized, respectively. As of September 30, 2020, the amount of unearned revenue from EMAs was $3.3 million. We expect to earn and recognize approximately $2.6 million of the unearned amount in the next 12 months and $0.7 million in periods beyond the next 12 months.

Each business segment designs, markets, sources, manufactures and sells recognized consumer and other end-user demanded branded products used in businesses, schools and homes. Product designs are tailored to end-user preferences in each geographic region, and where possible, leverage common engineering, design, and sourcing.

Our product categories include storage and organization; stapling; punching; laminating, shredding and binding machines; dry erase boards; notebooks; calendars; computer accessories; and do-it-yourself tools, among others. Our portfolio includes both globally and regionally recognized brands. The revenue in North America and International segments includes significant sales of consumer products that have very important, seasonal selling periods related to back-to-school and calendar year-end. For North America and Mexico, back-to-school straddles the second and third quarters, and for the Southern Hemisphere it takes place in the fourth and first quarter. We expect sales of consumer products to become a greater percentage of our revenue because demand for consumer back-to-school products is growing faster than demand for most business-related and calendar products.

Customers

We distribute our products through a wide variety of retail and commercial channels to ensure that they are readily and conveniently available for purchase by consumers and other end-users, wherever they prefer to shop. These channels include mass retailers; e-tailers; discount, drug/grocery and variety chains; warehouse clubs; hardware and specialty stores; independent office product dealers; office superstores; wholesalers; and contract stationers. We also sell directly to commercial and consumer end-users through our e-commerce sites and our direct sales organization.

Pending Litigation - Brazil Tax Assessments

In connection with our May 1, 2012, acquisition of the Mead C&OP business, we assumed all of the tax liabilities for the acquired foreign operations including Tilibra. For further information, see "Note 11. Income Taxes - Brazil Tax Assessments" for details on tax assessments issued by the FRD against Tilibra challenging the tax deduction of goodwill from Tilibra's taxable income for the years 2007 through 2010. If the FRD's initial position is ultimately sustained, payment of the amount assessed would materially and adversely affect our cash flow in the year of settlement.

Brazil Tax Credits

In March 2017, the Supreme Court of Brazil ruled against the Brazilian tax authority in a leading case related to the computation of certain indirect taxes. The Supreme Court ruled that the indirect tax base should not include a value-added tax known as "ICMS." The Supreme Court decision, in principle, affects all applicable judicial proceedings in progress, and reduces future indirect taxes on our Brazilian subsidiary, Tilibra. However, the Brazilian tax authority has filed an appeal seeking clarification of certain matters, including the amount by which taxpayers would be entitled to reduce their indirect tax base (i.e. the gross ICMS collected or the net ICMS paid). The appeal also requests a modulation of the decision’s effects, which may limit its retrospective impact on taxpayers, including Tilibra.

Tilibra has paid and continues to pay these indirect taxes on a tax base which includes the gross ICMS collected. It has also filed legal actions in Brazil to request reimbursement of these excess tax payments by way of future credits ("Tax Credits") and for permission to exclude the gross ICMS collected from the tax base in future periods. Tilibra’s legal actions cover various

time periods and some have been finally decided in a court of law in favor of Tilibra, while others are still pending a final decision.

Due to the uncertainties associated with the scope of the application of the Brazilian Supreme Court’s ruling, taking into account the Brazilian tax authority’s appeal and request for modulation, the Company has and will recognize income only for the amount of Tax Credits actually monetized, which will occur when Tilibra receives a cash flow benefit from applying the Tax Credits against various taxes payable in Brazil. The benefit of the Tax Credits realized by the Company has and will be recorded in the Consolidated Statements of Income in the line item "Other expense (income), net."

Tilibra received final decisions for Tax Credits in the amount of $4.3 million, of which $3.3 million was offset against Brazilian taxes in the fourth quarter of 2019, with the balance used during the first quarter of 2020. This amount of Tax Credits assumes that only the net amount of ICMS paid can be excluded from the tax base. The total value of these Tax Credits was recorded as a gain in Tilibra’s local statutory accounts during the third quarter of 2019, resulting in Brazilian federal taxes payable of approximately $1.6 million.

Final decisions in the remaining legal actions Tilibra has filed may result in additional Tax Credits that could be monetized in future periods. Further, a favorable decision in the leading case by the Brazilian Supreme Court on the methodology to compute the Tax Credits (i.e. gross ICMS collected) would result in additional Tax Credits being available to Tilibra. The amount of these additional Tax Credits may be material.

Foroni, in years prior to the acquisition, also filed legal actions in Brazil to recover these excess indirect tax payments; however, all of Foroni's claims are still pending a final decision. In the event any Tax Credits are recovered on behalf of Foroni, we are required under the quota purchase agreement to remit such recovery to the former owners of Foroni on a net income tax paid basis, and therefore will not recognize any benefit in the Consolidated Statements of Income.

Other Pending Litigation

We are party to various lawsuits and regulatory proceedings, primarily related to alleged patent infringement, as well as other 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 costly and time-consuming and might require us to pay monetary damages or enter into costly license agreements. We also may be subject to injunctions against development and sale of certain of our products.

It is the opinion of management that (other than the Brazil Tax Assessments) the ultimate resolution of currently outstanding matters will 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 be successful in our 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.

Environmental

We are subject to national, state, provincial and/or local environmental laws and regulations concerning the discharge of materials into the environment and the handling, disposal and clean-up of waste materials and other items relating to the protection of the environment. This includes environmental laws and regulations that affect the design and composition of certain of our products. 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 and results of operations or competitive position.
