Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	Basis of Presentation and Summary of Significant Accounting Policies Nature of Operations —As a worldwide marketing solutions partner, Quad leverages its 50-year heritage of platform excellence, innovation, strong culture and social purpose to create a better way for its clients, employees and communities. The Company’s integrated marketing platform helps brands and marketers reduce complexity, increase efficiency and enhance marketing spend effectiveness. Quad provides its clients with unmatched scale for on-site services and expanded subject expertise in marketing strategy, creative solutions, media deployment and marketing management services. With a client-centric approach that drives the Company to continuously evolve its offering, combined with leading-edge technology and single-source simplicity, the Company has the resources and knowledge to help a wide variety of clients in multiple vertical industries, including retail, publishing, consumer technology, consumer packaged goods, financial services, insurance, healthcare and direct-to-consumer. The Company operates primarily in the commercial print portion of the printing industry as a printer of retail inserts, publications, catalogs, special interest publications, journals, direct mail, directories, in-store marketing and promotion, packaging, newspapers, custom print products, other commercial and specialty printed products and global paper procurement. The Company’s products and services for a variety of industries are sold primarily throughout North America, South America and Europe. In addition, the Company strategically sources packaging product manufacturing over multiple end markets in Central America and Asia. Principles of Consolidation and Basis of Presentation —The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned and majority-owned controlled subsidiaries and have been prepared in accordance with GAAP. The results of operations and accounts of businesses acquired are included in the consolidated financial statements from the dates of acquisition (see Note 3, “Acquisitions and Strategic Investments”). Investments in entities where the Company has both the ability to exert significant influence but not control and an ownership interest of 50% or less but more than 20% are accounted for using the equity method of accounting. Investments in entities where the Company does not exert significant influence or control and has an ownership interest of less than 20% are accounted for using the cost method of accounting. Intercompany transactions and balances have been eliminated in consolidation. Discontinued Operations —The results of operations of the Company’s Book business have been reported as discontinued operations for all periods presented, in accordance with Accounting Standards Codification (“ASC”) 205-20 — Discontinued Operations . The corresponding current and long-term assets and liabilities of the Book business have been classified as held for sale in the consolidated balance sheets in accordance with ASC 205-20 as of December 31, 2019. The sale of the Book business was completed during 2020. The financial information pertaining to discontinued operations has been excluded from all relevant notes to the consolidated financial statements, unless otherwise noted. See all required disclosures and further information in Note 4, “Discontinued Operations” for information about the Company’s sale of its Book business. Foreign Operations —Assets and liabilities denominated in foreign currencies are translated into United States dollars at the exchange rate existing at the respective balance sheet dates. Income and expense items are translated at the average rates during the respective periods. Translation adjustments resulting from fluctuations in exchange rates are recorded as a separate component of accumulated other comprehensive income (loss) on the consolidated statements of shareholders’ equity, while transaction gains and losses are recorded in selling, general and administrative expenses on the consolidated statements of operations. Foreign exchange transactions resulted in losses of $2.0 million during the year ended December 31, 2020 and gains of $1.2 million during the year ended December 31, 2019. The Company had a 49% interest in Plural, a commercial printer based in São Paulo, Brazil, as of December 31, 2020. The Company accounts for this entity using the equity method of accounting. The Company’s equity in the (earnings) loss of Plural’s operations was recorded in equity in (earnings) loss of unconsolidated entity in the Company’s consolidated statements of operations, and was included within the International segment. Distributions received from equity method investees follow the nature of the distribution approach, where each distribution is evaluated on the basis of the source of the payment and is classified as either operating cash inflows or investing cash inflows. The Company reviews its equity method investment regularly for indicators of other than temporary impairment. Quad had no other significant unconsolidated entities as of December 31, 2020. Use of Estimates —The preparation of consolidated financial statements requires the use of management’s estimates and assumptions that affect the reported assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from these estimates. Estimates are used when accounting for items and matters including, but not limited to: allowances for doubtful accounts, inventory obsolescence, asset valuations and useful lives, pension and postretirement benefits, self-insurance reserves, stock-based compensation, taxes, restructuring and other provisions and contingencies. Revenue Recognition —The Company recognizes its products and services revenue based on when the transfer of control passes to the customer or when the service is completed and accepted by the customer. Under agreements with certain customers, products may be stored by the Company for future delivery. In these situations, the Company may receive warehouse management fees for the services it provides. Product returns are not significant because the products are customized; however, the Company accrues for the estimated amount of customer allowances at the time of sale based on historical experience and known trends. Revenue from services is recognized as services are performed. Revenues related to the Company’s imaging operations, which include digital content management, photography, color services and page production, are recognized in accordance with the terms of the contract, typically upon completion of the performed service and acceptance by the customer. Revenues related to the Company’s logistics operations, which includes the delivery of printed material, are recognized upon completion of services. Certain revenues earned by the Company require judgment to determine if revenue should be recorded gross as a principal or net of related costs as an agent. Billings for third-party shipping and handling costs, primarily in the Company’s logistics operations, and out-of-pocket expenses are recorded gross in net sales and cost of sales in the consolidated statements of operations. Many of the Company’s operations process materials, primarily paper, that may be supplied directly by customers or may be purchased by the Company and sold to customers. No revenue is recognized for customer-supplied paper. Revenues for Company-supplied paper are recognized on a gross basis. Byproduct Recoveries —The Company presents byproduct recoveries as a reduction of cost of sales–products in the consolidated statements of operations. Classification of byproduct recoveries as a reduction of cost of sales aligns the proceeds from byproduct recoveries with the corresponding manufacturing costs. Financial Instruments —The Company uses derivative financial instruments for the purpose of hedging interest rate, commodity and foreign exchange exposures that exist as part of ongoing business operations, including interest rate swap agreements, natural gas forward purchase contracts and foreign exchange contracts. As a policy, the Company does not engage in speculative or leveraged transactions, nor does the Company hold or issue financial instruments for trading purposes. Derivative instruments are recorded on the consolidated balance sheets as either assets or liabilities measured at their fair value. If the derivative is designated as a fair value hedge, the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are recognized in earnings. If the derivative is designated as a cash flow hedge, the effective portion of the changes in the fair value of the derivative are recorded as a component of accumulated other comprehensive income (loss) and recognized in the consolidated statements of operations when the hedged item affects earnings. The ineffective portions of the changes in the fair value of hedges are insignificant and recognized in earnings. Cash flows from derivatives that are accounted for as cash flow or fair value hedges are included in the consolidated statements of cash flows in the same category as the item being hedged. Fair Value Measurement —The Company applies fair value accounting for all assets and liabilities that are recognized or disclosed at fair value in its consolidated financial statements on a recurring basis. Fair value represents the amount that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities that are required to be recorded at fair value, the Company considers the principal or most advantageous market and the market-based risk measurements or assumptions that market participants would use in pricing the asset or liability. See Note 15, “Financial Instruments and Fair Value Measurements,” for further discussion. Research and Development —Research and development costs related to the development of new products or the adaptation of existing products are expensed as incurred, included in cost of sales and totaled $3.0 million and $3.6 million during the years ended December 31, 2020 and 2019, respectively. Cash and Cash Equivalents and Restricted Cash —The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. Receivables —Receivables are stated net of allowances for credit losses. No single customer comprised more than 5% of the Company’s consolidated net sales in 2020 or 2019, or 5% of the Company’s consolidated receivables as of December 31, 2020 or 2019. On January 1, 2020, the Company adopted Accounting Standards Update 2016-13 “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”), which changes the impairment model for most financial assets and certain other instruments. This new impairment model, also known as the current expected credit loss (“CECL”) model, is based on expected losses rather than incurred losses. Under ASC 326— Financial Instruments — Credit Losses (“ASC 326”), the Company is required to measure expected credit losses for financial instruments, including trade receivables, based on historical experience, current conditions and reasonable forecasts. The Company has adopted ASU 2016-13 using a modified retrospective transition approach and has recorded a cumulative-effect transition adjustment to accumulated deficit to increase the allowance for credit losses balance as of January 1, 2020. See Note 7, “Receivables,” for further discussion on the transactions affecting the allowances for doubtful accounts. Inventories —Inventories include material, labor, and plant overhead and are stated at the lower of cost or net realizable value. At December 31, 2020 and 2019, all inventories were valued using the first-in, first-out method. See Note 8, “Inventories,” for the components of the Company’s inventories. Leases —On January 1, 2019, the Company adopted Accounting Standards Update 2016-02, “Leases (Topic 842)” (“ASU 2016-02”), which establishes a right-of-use model requiring a lessee to record a right-of-use asset and a lease liability on the balance sheet for all leases with terms longer than twelve months. Leases are classified as either finance or operating, with classification affecting the pattern of expense recognition. The Company adopted ASU 2016-02 using the modified retrospective approach and applied the new guidance under ASC 842 — Leases (“ASC 842”) to those contracts existing at, or entered into after, January 1, 2019. See Note 13, “Leases,” for additional accounting policy and transition disclosures. Property, Plant and Equipment —Property, plant and equipment are recorded at cost, and are depreciated over the estimated useful lives of the assets using the straight-line method for financial reporting purposes. See Note 9, “Property, Plant and Equipment,” for the components of the Company’s property, plant and equipment. Major improvements that extend the useful lives of existing assets are capitalized and charged to the asset accounts. Repairs and maintenance, which do not significantly improve or extend the useful lives of the respective assets, are expensed as incurred. Leasehold improvements are depreciated over the shorter of the lease term or the estimated useful life of the respective asset. When an asset is retired or disposed, the associated costs and accumulated depreciation are eliminated, and the resulting gain or loss is recognized in the Company’s consolidated statements of operations. Asset Category Range of Useful Lives Buildings 10 to 40 Years Machinery and equipment 3 to 15 Years Other 3 to 10 Years Other Intangible Assets —Identifiable intangible assets are recognized apart from goodwill and are amortized over their estimated useful lives. Impairment of Long-Lived and Other Intangible Assets —The Company evaluates long-lived assets and other intangible assets (of which the most significant are property, plant and equipment; right-of-use assets and customer relationship intangible assets) whenever events and circumstances have occurred that indicate the carrying value of an asset may not be recoverable. Determining whether impairment has occurred typically requires various estimates and assumptions, including determining which cash flows are directly related to the potentially impaired asset, the useful life over which cash flows will occur, their amount and the asset’s residual value, if any. In turn, assessing whether there is an impairment loss requires a determination of recoverability, which is generally estimated by the ability to recover the balance of the assets from expected future operating cash flows on an undiscounted basis. If impairment is determined to exist, any related impairment loss is calculated based on the difference in the fair value and carrying value of the asset. Goodwill —Goodwill is reviewed annually for impairment as of October 31, or more frequently if events or changes in circumstances indicate that it is more likely than not that the fair value of a reporting unit is below its carrying value. In performing this analysis, the Company compares each reporting unit’s fair value to its carrying value. The fair value is estimated based on comparable company market valuations and/or expected future discounted cash flows to be generated by the reporting unit. If the carrying value exceeds the reporting unit’s fair value, an impairment loss would be charged to operations in the period identified. See Note 6, “Goodwill and Other Intangible Assets,” for further discussion. Income Taxes —The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of items reported in the financial statements. Under this method, deferred tax assets and liabilities are measured based on the differences between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the effective date of enactment. The Company records net deferred tax assets to the extent the Company believes these assets will more likely than not be realized. This determination is based upon all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies, and recent financial operations. If the Company determines that a deferred income tax asset will not be fully realized in the future, then a valuation allowance is established or increased to reflect the amount at which the asset will more likely than not be realized, which would increase the Company’s provision for income taxes. In a period after a valuation allowance has been established, if the Company determines the related deferred income tax assets will be realized in the future in excess of their net recorded amount, then an adjustment to reduce the related valuation allowance will be made, which would reduce the Company’s provision for income taxes. The Company is regularly audited by foreign and domestic tax authorities. These audits occasionally result in proposed assessments where the ultimate resolution might result in the Company owing additional taxes, including in some cases, penalties and interest. The Company recognizes a tax position in its consolidated financial statements when it is more likely than not that the position would be sustained upon examination by tax authorities. This recognized tax position is then measured at the largest amount of benefit that is more likely than not of being recognized upon ultimate settlement. The Company recognizes interest and penalties related to unrecognized tax benefits in income tax expense. The determination of the Company’s worldwide tax provision and related tax assets and liabilities requires the use of significant judgment in estimating the impact of uncertainties in the application of GAAP and the interpretation of complex tax laws. In the ordinary course of business, there are transactions and calculations where the final tax outcome is uncertain. Where fair market value is required to measure a tax asset or liability for GAAP purposes, the Company periodically obtains independent, third party assistance to validate that such value is determined in conformity with Internal Revenue Service fair market value guidelines. While the Company believes it has the appropriate support for the positions taken, certain positions may be successfully challenged by taxing authorities. Resolution of these uncertainties in a manner inconsistent with management’s expectations could have a material impact on the Company’s financial condition and operating results. The Company applies the provisions of the authoritative guidance on accounting for uncertain tax positions to determine the appropriate amount of tax benefits to be recognized with respect to uncertain tax positions. The determination of the Company’s worldwide tax provision includes the impact of any changes to the amount of tax benefits recognized with respect to uncertain tax positions. See Note 14, “Income Taxes,” for further discussion. Pension Plans —The Company assumed certain frozen underfunded defined benefit pension plans as part of the 2010 World Color Press acquisition. Pension plan costs are determined using actuarial methods and are funded through contributions. The Company records amounts relating to its pension plans based on calculations which include various actuarial assumptions including discount rates, assumed rates of return, and mortality. The Company reviews its actuarial assumptions on an annual basis and modifies the assumptions based on current rates and trends when it is appropriate to do so. The effects of modifications are recognized immediately on the consolidated balance sheets, but are generally amortized into operating income over future periods, with the deferred amount recorded in accumulated other comprehensive loss on the consolidated balance sheets. The Company believes that the assumptions utilized in recording its obligations under its plans are reasonable based on its experience, market conditions and input from its actuaries and investment advisors. For the purposes of calculating the expected return on plan assets, those assets are valued at fair value. When an event gives rise to both a curtailment and a settlement, the curtailment is accounted for prior to the settlement. The Company’s measurement date to measure the defined benefit plan assets and the projected benefit obligation is December 31. The Company has previously participated in MEPPs as a result of the acquisition of World Color Press. Due to the significant underfunded status of the MEPPs, the Company has withdrawn from all significant MEPPs and replaced these union sponsored “promise to pay in the future” defined benefit plans with a Company sponsored “pay as you go” defined contribution plan, which is the form of retirement benefit provided to Quad’s employees. As a result of the decision to withdraw, the Company recorded an estimated withdrawal liability for the MEPPs as part of the World Color Press purchase price allocation process based on information received from the MEPPs’ trustees. See Note 16, “Employee Retirement Plans,” for further discussion. Stock-Based Compensation —The Company recognizes stock-based compensation expense over the vesting period for all stock-based awards made to employees and directors based on the fair value of the instrument at the time of grant. Equity awards accounted for as liabilities are recorded at fair value on the initial issuance date and are remeasured to fair value at each reporting period, with the change in fair value being recorded in selling, general and administrative expense in the consolidated statements of operations. See Note 18, “Equity Incentive Programs,” for further discussion. Accumulated Other Comprehensive Income (Loss) —Accumulated other comprehensive income (loss) consists primarily of unrecognized actuarial gains and losses and prior service costs for pension plans, foreign currency translation adjustments and interest rate swap adjustments, and is presented in the consolidated statements of shareholders’ equity. See Note 20, “Accumulated Other Comprehensive Loss,” for further discussion. The COVID-19 Pandemic Impacts and Response —The COVID-19 pandemic has had, and will continue to have, a negative impact on the Company’s business, financial condition, cash flows, results of operations and supply chain, although the full extent is still uncertain. The Company implemented cost reduction and cash conservation initiatives in response to the impact of the COVID-19 pandemic on its business, including implementing a COVID-19 Temporary Furlough Program through which employees take an unpaid leave of absence – the length of which varies upon business needs; temporary salary reductions for leaders through the end of July 2020, including a 50% salary reduction for the Chief Executive Officer and a 35% salary reduction for named executive officers; a temporary 50% reduction in retainer fees for the Company’s non-employee directors; temporarily suspending use of vacation and vacation payouts through the end of June 2020; temporarily suspending production at several manufacturing facilities where declining client volume or other effects of the pandemic impacted the Company’s ability to operate, all of which resumed operations by the end of September 2020; suspending quarterly dividend payments until further notice; and delaying capital spending projects. The Company also announced the permanent closures of the facilities located in the following locations as a result of ongoing volume declines, particularly in retail, that have been exacerbated by the COVID-19 pandemic during the year ended December 31, 2020: (1) Taunton, Massachusetts; (2) Fernley, Nevada; (3) Nashville, Tennessee; (4) Oklahoma City, Oklahoma; and (5) Charlotte, North Carolina. In addition, the Company amended its Senior Secured Credit Facility during the second quarter of 2020 to provide for certain financial covenant relief through the fiscal quarter ending September 30, 2021. The Company is continuing to evaluate its cost structure and expects to implement additional cost reduction measures as necessary. As the pandemic continues, the extent of the impact on the Company’s business, financial condition, cash flows, results of operations and supply chain will depend on future developments, all of which are still highly uncertain and cannot be predicted. Supplemental Cash Flow Information —The following table summarizes certain supplemental cash flow information for the years ended December 31, 2020 and 2019: 2020 2019 Interest paid, net of amounts capitalized $ 52.3 $ 77.1 Income taxes paid 2.7 9.2 Non-cash investing and financing activities: Non-cash finance lease additions 1.4 7.7 Non-cash operating lease additions 15.0 10.1 Acquisitions of businesses (see Note 3): Fair value of assets acquired, net of cash 5.0 97.2 Liabilities assumed (2.8) (31.5) Goodwill — 58.5 Equity incentive awards — (3.2) Acquisition of businesses—net of cash acquired $ 2.2 $ 121.0

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition Revenue Disaggregation The following table provides information about disaggregated revenue by the Company’s operating segments and major products and services offerings for the years ended December 31, 2020 and 2019: United States Print International Total Year ended December 31, 2020 Catalog, publications, retail inserts and directories $ 1,402.0 $ 230.0 $ 1,632.0 Direct mail and other printed products 538.3 53.3 591.6 Other 3.7 1.4 5.1 Total Products 1,944.0 284.7 2,228.7 Logistics services 357.2 17.2 374.4 Imaging, marketing services and other services 326.4 0.1 326.5 Total Services 683.6 17.3 700.9 Total Net Sales $ 2,627.6 $ 302.0 $ 2,929.6 Year ended December 31, 2019 Catalog, publications, retail inserts and directories $ 2,014.7 $ 301.0 $ 2,315.7 Direct mail and other printed products 681.6 83.7 765.3 Other 17.0 0.3 17.3 Total Products 2,713.3 385.0 3,098.3 Logistics services 429.4 17.0 446.4 Imaging, marketing services and other services 378.3 0.4 378.7 Total Services 807.7 17.4 825.1 Total Net Sales $ 3,521.0 $ 402.4 $ 3,923.4 Nature of Products and Services The Company recognizes its products and services revenue based on when the transfer of control passes to the client or when the service is completed and accepted by the client. The products offering is predominantly comprised of the Company’s print operations which includes retail inserts, publications, catalogs, special interest publications, journals, direct mail, directories, in-store marketing and promotion, packaging, newspapers, custom print products, other commercial and specialty printed products and global paper procurement. The Company considers its logistic operations as services, which include the delivery of printed material. The services offering also includes revenues related to the Company’s imaging operations, which include digital content management, photography, color services, page production, marketing services, media planning and placement, facilities management and medical services. Performance Obligations At contract inception, the Company assesses the products and services promised in its contracts with customers and identifies performance obligations for each promise to transfer to the customer a product or service that is distinct. To identify the performance obligations, the Company considers the goods or services promised in the contract regardless of whether they are explicitly stated or are implied by customary business practices. The Company determined that the following distinct products and services represent separate performance obligations: • Pre-Press Services • Print • Other Services For Pre-Press and Other Services, the Company recognizes revenue at point-in-time upon completion of the performed service and acceptance by the customer. The Company considers transfer of control to occur once the service is performed as the Company has right to payment and the customer has legal title and risk and reward of ownership. The Company recognizes its Print revenues upon transfer of title and the passage of risk of loss, which is point-in-time upon shipment to the customer, and when there is a reasonable assurance as to collectability. Revenues related to the Company’s logistics operations, which includes the delivery of printed material, are included in the Print performance obligation and are also recognized at point-in-time as services are completed. Under agreements with certain customers, products may be stored by the Company for future delivery. In these situations, the Company may receive warehouse management fees for the services it provides. Revenue from warehouse management fees was immaterial for the years ended December 31, 2020 and 2019. Certain revenues earned by the Company require judgment to determine if revenue should be recorded gross as principal or net of related costs as an agent. Billings for third-party shipping and handling costs, primarily in the Company’s logistics operations, and out-of-pocket expenses are recorded gross in net sales and cost of sales in the consolidated statements of operations. Many of the Company’s operations process materials, primarily paper, that may be supplied directly by customers or may be purchased by the Company and sold to customers. No revenue is recognized for customer-supplied paper. Revenues for the Company-supplied paper are recognized on a gross basis. In some cases, the Company will print items that are mailed to consumers and bill the customer for postage. In these cases, the Company is acting as an agent and billings are recorded on a net basis in net sales. Significant Payment Terms Payment terms and conditions for contracts with customers vary. The Company typically offers standard terms of net 30 days. It is not the Company’s standard business practice to offer extended payment terms longer than one year. The Company may offer cash discounts or prepayment and extended terms depending on certain facts and circumstances. As such, when the timing of the Company’s delivery of products and services differs from the timing of payment, the Company will record either a contract asset or a contract liability. Variable Consideration When evaluating the transaction price, the Company analyzes on a contract by contract basis all applicable variable considerations and non-cash consideration and also performs a constraint analysis. The nature of the Company’s contracts give rise to variable consideration, including, volume rebates, credits, discounts, and other similar items that generally decrease the transaction price. These variable amounts generally are credited to the customer, based on achieving certain levels of sales activity, when contracts are signed, or making payments within specific terms. Product returns are not significant because the products are customized; however, the Company accrues for the estimated amount of customer allowances at the time of sale based on historical experience and known trends. When the transaction price requires allocation to multiple performance obligations, the Company uses the estimated stand-alone selling prices using the adjusted market assessment approach. Costs to Obtain Contracts In accordance with ASC 606 — Revenue from Contracts with Customers (“ASC 606”), the Company capitalizes certain sales incentives of the sales compensation packages for costs that are directly attributed to being awarded a customer contract or renewal and would not have been incurred had the contract not been obtained. The Company also defers certain contract acquisition costs paid to the customer at contract inception. Costs to obtain contracts with a duration of less than one year are expensed as incurred. For all contract costs with contracts over one year, the Company amortizes the costs to obtain contracts on a straight-line basis over the estimated life of the contract and reviews quarterly for impairment. Activity impacting costs to obtain contracts for the year ended December 31, 2020, was as follows: Costs to Obtain Contracts Balance at January 1, 2020 $ 12.7 Costs to obtain contracts 1.0 Amortization of costs to obtain contracts (5.0) Balance at December 31, 2020 $ 8.7 Practical Expedients The Company has elected to apply the following practical expedients allowed under ASC 606: • For certain performance obligations related to print contracts, the Company has elected not to disclose the value of unsatisfied performance obligations for the following: (1) contracts that have an original expected length of one year or less; (2) contracts where revenue is recognized as invoiced; or (3) contracts with variable consideration related to unsatisfied performance obligations. The Company had zero volume commitments in contracts that extend beyond one year as of December 31, 2020. • The Company expenses costs to obtain contracts as incurred when the contract duration is less than one year. • The transaction amount is not adjusted for a significant financing component as the period between transfer of the products or services and payment is less than one year. • The Company accounts for shipping and handling activities, which includes postage, that occur after control of the related products or services transfers to the customer as fulfillment activities and are therefore recognized at time of shipping. • The Company excludes from its transaction price any amounts collected from customers for sales taxes.

Acquisitions and Strategic Investments	Acquisitions and Strategic Investments 2020 Change of Ownership in Rise Interactive On June 15, 2020, the Company purchased units of equity in Rise from a previous holder in the form of a $15.9 million note payable paid in full on October 1, 2020, and $1.0 million cash paid on June 15, 2020. In addition, on June 15, 2020, Rise purchased and retired units of equity from previous holders of Rise for $5.4 million in cash. These transactions resulted in the Company’s ownership interest changing from 57% to 99%. The Company began consolidating the results of Rise in the Company’s consolidated financial statements when its equity ownership increased to 57% on March 14, 2018. The portion of Rise’s operating results not owned by the Company of 43% through June 15, 2020 and of 1% after June 15, 2020 is recorded as net earnings (loss) attributable to noncontrolling interests on the consolidated statement of operations. The portion of net assets not owned by the Company is recorded as noncontrolling interests as of the respective dates shown on the consolidated balance sheets. 2019 Acquisition of Periscope On January 3, 2019, the Company completed the acquisition of Periscope, a creative agency headquartered in Minneapolis, Minnesota, for $121.0 million cash paid. Periscope provides a comprehensive service offering, including media buying and analytics, creative and account management. Periscope also has packaging design and premedia services that complement Quad’s print-production capabilities. The purchase price of $134.0 million includes $9.8 million of acquired cash and non-cash equity incentive awards with a grant date fair value of $3.2 million. Included in the purchase price allocation are $69.8 million of identifiable other intangible assets, which are amortized over their estimated useful lives, ranging from five Note 15, “Financial Instruments and Fair Value Measurements ,” for the definition of Level 3 inputs). Periscope’s operations are included in the United States Print and Related Services segment.

Discontinued Operations [Abstract]
Discontinued Operations	Discontinued Operations During the third quarter of 2019, the Company made a decision to sell its United States Book business as a part of an ongoing process to review its business portfolio and divest assets not core to the Company’s transformation strategy. Accordingly, the Company has classified the Book business as a discontinued operation, as required by ASC 205-20 — Discontinued Operations . The Book business primarily consists of three facilities: Versailles, Kentucky; Fairfield, Pennsylvania; and Martinsburg, West Virginia. The Company’s Book business has historically been included within the United States Print and Related Services segment and the Core Print and Related Services reporting unit. On July 1, 2020, the Company completed the sale of its Versailles, Kentucky book manufacturing plant to CJK Group, Inc., which serves book, magazine, catalog and journal publishers, for $7.0 million in cash and the assumption of approximately $3.0 million in finance lease obligation, resulting in a $10.1 million impairment charge related to property, plant and equipment and a $3.0 million gain on the sale of the business during the year ended December 31, 2020. Working capital was finalized during the third quarter of 2020. The Company used the proceeds from the sale to reduce debt. On October 31, 2020, the Company completed the sale of its Fairfield, Pennsylvania and Martinsburg, West Virginia book manufacturing plants to Berryville Graphics, a division of Bertelsmann Printing Group USA, a media, services and education company, for $14.2 million in cash, resulting in a loss on the sale of the business of $3.5 million and a $1.4 million impairment charge related to property plant and equipment during the year ended December 31, 2020. Working capital was finalized during the fourth quarter of 2020. The Company used the proceeds from the sale to reduce debt. This sale was the final step in the previously announced strategic decision to divest the Company’s Book business to optimize its product portfolio. The following table summarizes the results of operations of the Company’s Book business, which are included in the loss from discontinued operations in the consolidated statements of operations for the years ended December 31, 2020 and 2019. For The Year Ended December 31, 2020 2019 Total net sales $ 79.4 $ 213.8 Total cost of sales, excluding depreciation and amortization 80.4 226.8 Selling, general and administrative expenses 4.2 5.5 Depreciation and amortization — 13.6 Restructuring, impairment and transaction-related charges (1) 16.4 92.1 Goodwill impairment (2) — 10.1 Other expenses, net 0.3 0.1 Loss from discontinued operations before income taxes (21.9) (134.4) Income tax benefit — (33.8) Loss from discontinued operations, net of tax $ (21.9) $ (100.6) ______________________________ (1) The Company recognized $11.5 million of impairment charges for tangible property, plant and equipment during the year ended December 31, 2020, to reduce the carrying value of the Book business to its fair value, and recognized $2.2 million in employee termination charges and $2.7 million in other restructuring charges during the year ended December 31, 2020. Impairment charges recognized to reduce the carrying value of the Book business to its fair value during during the year ended December 31, 2019 included: $86.5 million of impairment charges for tangible property, plant and equipment and $5.6 million of impairment charges for contract assets. (2) The Book business was included in the Core Print and Related Services reporting unit. The amount of goodwill allocated to the Book business was determined based on the relative fair value of the Book business and the portion of the reporting unit that will be retained. Due to the decision to sell the Book business, the Company must determine whether any of the assets of the Book business were impaired. Therefore, management performed an interim goodwill impairment test. Due to the carrying value of the Book business net assets exceeding the estimated fair value, the Company recorded a $10.1 million goodwill impairment charge. The consolidated statements of cash flows for all periods have not been adjusted to separately disclose cash flows related to discontinued operations. Cash flows related to the Book business during the years ended December 31, 2020 and 2019 were as follows: For The Year Ended December 31, 2020 2019 Cash flows used in operating activities $ (3.9) $ (8.0) Cash flows provided by (used in) investing activities 19.6 (17.2) The following table summarizes the current and long-term assets and liabilities of the discontinued Book business that were classified as held for sale in the consolidated balance sheets at December 31, 2020, and 2019: December 31, December 31, Receivables—net $ — $ 19.6 Inventories — 14.0 Prepaid expenses and other current assets (1) — 23.0 Current assets of discontinued operations — 56.6 Property, plant and equipment—net — — Operating lease right-of-use assets—net — 0.2 Goodwill — — Other long-term assets — 0.3 Long-term assets of discontinued operations — 0.5 Accounts payable — 7.0 Other current liabilities — 8.5 Current portion of finance lease obligations — 0.1 Current portion of operating lease obligations — 0.2 Current liabilities of discontinued operations — 15.8 Finance lease obligations — — Other long-term liabilities — 0.6 Long-term liabilities of discontinued operations — 0.6 ______________________________ (1) Includes land and building assets that were reclassified to other current assets as of December 31, 2019 .

Restructuring, Impairment and Transaction-Related Charges	Dec. 31, 2020
Restructuring and Related Activities [Abstract]
Restructuring, Impairment and Transaction-Related Charges	Restructuring, Impairment and Transaction-Related Charges The Company recorded restructuring, impairment and transaction-related charges for the years ended December 31, 2020 and 2019, as follows: 2020 2019 Employee termination charges $ 34.7 $ 22.2 Impairment charges 64.1 7.9 Transaction-related charges 1.4 51.6 Integration costs 1.9 3.3 Other restructuring charges 22.0 4.4 Total $ 124.1 $ 89.4 The costs related to these activities have been recorded on the consolidated statements of operations as restructuring, impairment and transaction-related charges. See Note 21, “Segment Information,” for restructuring, impairment and transaction-related charges by segment. Restructuring Charges The Company began a restructuring program in 2010 related to eliminating excess manufacturing capacity and properly aligning its cost structure. The Company has announced a total of 50 plant closures since 2010. The Company announced the closures of the facilities located in Charlotte, North Carolina; Taunton, Massachusetts (retail facility); Fernley, Nevada; Nashville, Tennessee; and Oklahoma City, Oklahoma during the year ended December 31, 2020. The Company classifies the following charges as restructuring: • Employee termination charges are incurred when the Company reduces its workforce through facility consolidations and separation programs. • Integration costs are incurred primarily for the integration of acquired companies (see Note 3, “Acquisitions and Strategic Investments,” for descriptions of the Company’s recent acquisitions). • Other restructuring charges are comprised of the following components and are presented net of any gains on the sale of facilities and businesses. During the year ended December 31, 2020, the Company recognized gains from the sale of the facilities located in Midland, Michigan and Shakopee, Minnesota. During the year ended December 31, 2019, the Company recognized an $8.4 million gain on the sale of a business, as well as gains from the sale of the facilities located in Franklin, Kentucky and Hazleton, Pennsylvania. Year Ended December 31, 2020 2019 Vacant facility carrying costs and lease exit charges $ 11.5 $ 9.5 Equipment and infrastructure removal costs 1.1 0.4 Gains on the sale of facilities (1.6) (6.1) Other restructuring activities 11.0 0.6 Other restructuring charges $ 22.0 $ 4.4 The restructuring charges recorded were based on plans that have been committed to by management and were, in part, based upon management’s best estimates of future events. Changes to the estimates may require future restructuring charges and adjustments to the restructuring liabilities. The Company expects to incur additional restructuring charges related to these and other initiatives. Impairment Charges The Company recognized impairment charges of $64.1 million during the year ended December 31, 2020, which consisted of $22.1 million, for machinery and equipment no longer being utilized in production as a result of facility consolidations, as well as other capacity reduction restructuring activities; and $42.0 million of land and building impairment charges. The Company recognized impairment charges of $7.9 million during the year ended December 31, 2019, which consisted of $7.6 million of impairment charges primarily for machinery and equipment no longer being utilized in production as a result of facility consolidations, as well as other capacity reduction restructuring activities; and $0.3 million of land and building impairment charges. Additional impairment charges were recorded related to the Book business during the year ended December 31, 2019, which are disclosed in Note 4, “Discontinued Operations”. The fair values of the impaired assets were determined by the Company to be Level 3 under the fair value hierarchy (see Note 15, “Financial Instruments and Fair Value Measurements,” for the definition of Level 3 inputs) and were estimated based on broker quotes, internal expertise related to current marketplace conditions and estimated future discounted cash flows. These assets were adjusted to their estimated fair values at the time of impairment. If estimated fair values subsequently decline, the carrying values of the assets are adjusted accordingly. Transaction-Related Charges The Company incurs transaction-related charges primarily consisting of professional service fees related to business acquisition and divestiture activities. The Company recognized transaction-related charges of $1.4 million and $51.6 million during the years ended December 31, 2020 and 2019, respectively.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill Goodwill represents the excess of the purchase price over the fair value of identifiable net assets acquired in a business combination. Goodwill is assigned to specific reporting units and is tested annually for impairment as of October 31, or more frequently if events or changes in circumstances indicate that it is more likely than not that the fair value of a reporting unit is below its carrying value. Due to the decline in the Company’s stock price and the uncertainty and impacts of the COVID-19 pandemic on the Company and the global economy, an interim goodwill impairment test was completed on the goodwill in the Core Print and Related Services reporting unit during the first quarter of 2020. As a result, the Company determined the fair value of the Core Print and Related Services reporting unit exceeded the carrying value, and therefore no impairment was recorded. The Company completed its annual impairment test as of October 31, 2020, and identified no indicators of impairment in any of the Company's reporting units during the year ended December 31, 2020. Due to the Company’s decision to sell its Book business, an interim goodwill impairment test was completed on the remaining goodwill in the Core Print and Related Services reporting unit during the third quarter of 2019. Due to the carrying value of the Book business net assets exceeding the estimated fair value, the Company recorded a $10.1 million goodwill impairment charge related to the Book business during the third quarter of 2019 (see Note 4, “Discontinued Operations”). In addition, the remaining goodwill that is not allocated to a business to be sold must be tested for impairment. No goodwill impairment was recorded on the remaining $103.0 million related to the retained portion of the Core Print and Related Services reporting unit during the year ended December 31, 2019. Fair value was determined using an equal weighting of both the income and market approaches. Under the income approach, the Company determined fair value based on estimated future cash flows discounted by an estimated weighted-average cost of capital, which reflects the overall level of inherent risk and the rate of return an outside investor would expect to earn. Under the market approach, the Company derived the fair value of the reporting units based on market multiples of comparable publicly-traded companies. This fair value determination was categorized as Level 3 in the fair value hierarchy (see Note 15, “Financial Instruments and Fair Value Measurements,” for the definition of Level 3 inputs). No goodwill impairment charges were recorded related to the Company’s continuing operations during the years ended December 31, 2020 or 2019. The accumulated goodwill impairment losses and the carrying value of goodwill from continuing operations at December 31, 2020 and 2019, were as follows: United States Print and Related Services International Total Goodwill $ 881.3 $ 30.0 $ 911.3 Accumulated goodwill impairment loss (778.3) (30.0) (808.3) Goodwill, net of accumulated goodwill impairment loss $ 103.0 $ — $ 103.0 There was no activity impacting goodwill for the year ended December 31, 2020.

Receivables	ReceivablesThe Company adopted ASU 2016-13 as of January 1, 2020, using a modified retrospective transition approach and has recorded a cumulative-effect transition adjustment to accumulated deficit as of January 1, 2020. The transition adjustment of $6.3 million to accumulated deficit included an $8.4 million increase in the allowance for credit losses, partially offset by a $2.1 million increase in deferred tax benefit. The transition had no impact to the consolidated statement of operations. Prior to granting credit, the Company evaluates each client in an underwriting process, taking into consideration the prospective client’s financial condition, past payment experience, credit bureau information and other financial and qualitative factors that may affect the client’s ability to pay. Specific credit reviews and standard industry credit scoring models are used in performing this evaluation. Clients’ financial condition is continuously monitored as part of the normal course of business. Some of the Company’s clients are highly leveraged or otherwise subject to their own operating and regulatory risks. Specific client provisions are made when a review of significant outstanding amounts, utilizing information about client creditworthiness, as well as current and future economic trends based on reasonable forecasts, indicates that collection is doubtful. The Company also records a general provision based on the overall risk profile of the receivables and through the assessment of reasonable economic forecasts. The risk profile is assessed on a quarterly basis using various methods, including external resources and credit scoring models. Accounts that are deemed uncollectible are written off when all reasonable collection efforts have been exhausted. The Company has recorded a credit loss expense of $9.1 million and $5.6 million during the years ended December 31, 2020 and 2019, respectively, which is included in selling, general and administrative expenses in the consolidated statements of operations. Receivables are stated net of allowances for credit losses in the consolidated balance sheets. Based on the clients’ account reviews and the continued uncertainty of the global economy, the Company has established an allowance for credit losses of $33.8 million as of December 31, 2020, and $25.0 million as of December 31, 2019. 2020 2019 Balance at beginning of year $ 25.0 $ 27.4 Transition adjustment for adoption of ASU 2016-13 8.4 — Balance at beginning of year, including transition adjustment 33.4 27.4 Provisions 9.1 5.6 Write-offs (8.8) (7.8) Translation and other 0.1 (0.2) Balance at end of year $ 33.8 $ 25.0

As of December 31, 2020, the borrowings outstanding under the Master Note and Security Agreement were $15.6 million. The senior notes under the Master Note and Security Agreement had a weighted average interest rate of 7.78% at December 31, 2020, which is fixed to maturity, with interest payable semiannually. Principal payments commenced September 1997 and extend through April 2026 in various tranches. The notes are collateralized by certain United States press equipment under the terms of the Master Note and Security Agreement. The Company redeemed $37.6 million of its senior notes under the Master Note and Security Agreement, at par (the outstanding principal balance as of the date of payment), during the year ended December 31, 2020. There was no direct gain or loss recognized as a result of the tender as all notes were redeemed at par; however, $0.2 million of unamortized debt issuance costs related to the tendered notes were recognized as a loss on debt extinguishment during the year ended December 31, 2020. All tendered senior notes under the Master Note and Security Agreement were canceled. The Company used cash flows from operating activities and borrowings under its revolving credit facility to fund the tender. The tender was primarily completed to reallocate debt to the lower interest rate revolving credit facility and thereby reduce interest expense based on current LIBOR rates. Senior Secured Credit Facility On April 28, 2014, the Company entered into its Senior Secured Credit Facility, which included a revolving credit facility, Term Loan A and Term Loan B. The Company completed the third amendment to the Senior Secured Credit Facility on January 31, 2019. This third amendment was completed to provide Quad with the liquidity and structural flexibility to consummate the proposed, but now terminated, acquisition of LSC and to extend existing maturities by (a) increasing the aggregate amount of the existing revolving credit facility from $725.0 million to $800.0 million with a term of five years, maturing on January 31, 2024; (b) increasing the aggregate amount of the existing Term Loan A from $375.0 million to $825.0 million with a delayed draw feature and term of five years, maturing on January 31, 2024; and (c) increasing the aggregate amount of the existing Term Loan B from $300.0 million to $500.0 million with a term of seven years, maturing on January 31, 2026. The Company intended that the loans available under the amended revolving credit facility would be used to repay, refinance, repurchase, redeem, exchange or otherwise terminate LSC’s existing indebtedness in connection with the consummation of the merger, and to pay transaction expenses. On July 26, 2019, following the termination of the proposed acquisition of LSC, Quad fully funded the $825.0 million delayed draw Term Loan A to retire the entire amount outstanding on the $500.0 million Term Loan B and reduced the borrowings under the revolving credit facility. The Company completed the fourth amendment to the Senior Secured Credit Facility on June 29, 2020. The Senior Secured Credit Facility was amended to (a) provide for certain financial covenant relief through the fiscal quarter ending September 30, 2021 (the Covenant Relief Period); (b) reduce the aggregate amount of the existing revolving credit facility from $800.0 million to $500.0 million; (c) make certain adjustments to pricing such as the addition of a 0.75% LIBOR floor; and (d) prohibit repurchases of capital stock and payments of cash dividends during the Covenant Relief Period. Certain amendments were also made to the quarterly financial covenants to which the Company is subject, which are further described below. At December 31, 2020, the Company had no outstanding borrowings on the revolving credit facility, and had $38.6 million of issued letters of credit, leaving $461.4 million available for future borrowings. Borrowings under the revolving credit facility and delayed draw Term Loan A made under the Senior Secured Credit Facility at December 31, 2020, bear interest at 2.50% in excess of reserve adjusted LIBOR, with a LIBOR floor of 0.75%, or 1.50% in excess of an alternate base rate. The Senior Secured Credit Facility is secured by substantially all of the unencumbered assets of the Company. The Senior Secured Credit Facility also requires the Company to provide additional collateral to the lenders in certain limited circumstances. Senior Unsecured Notes The Company issued $300.0 million aggregate principal amount of its Senior Unsecured Notes due May 1, 2022, on April 28, 2014. The Senior Unsecured Notes bear interest at 7.0%, and interest is payable semi-annually. The Senior Unsecured Notes were issued to extend and stagger the Company’s debt maturity profile, further diversify its capital structure and provide more borrowing capacity to better position the Company to execute on its strategic goals. The Company received $294.8 million in net proceeds from the sale of the Senior Unsecured Notes, after deducting the initial purchasers’ discounts and commissions. The proceeds from the Senior Unsecured Notes were used for the same purposes detailed above for the Senior Secured Credit Facility. The Company repurchased $4.7 million of its outstanding Senior Unsecured Notes in the open market, resulting in a net gain on debt extinguishment of $0.8 million during the year ended December 31, 2020. All repurchased Senior Unsecured Notes were canceled. The Company used cash flows from operating activities and borrowings under its revolving credit facility to fund the repurchases. These repurchases were primarily completed to reallocate debt to the lower interest rate revolving credit facility and thereby reduce interest expense based on current LIBOR rates. Each of the Company’s existing and future domestic subsidiaries that is a borrower or guarantees indebtedness under the Company’s Senior Secured Credit Facility or that guarantees certain of the Company’s other indebtedness or indebtedness of the Company’s restricted subsidiaries (other than intercompany indebtedness) fully and unconditionally guarantee or, in the case of future subsidiaries, will guarantee, on a joint and several basis, the Senior Unsecured Notes (the “Guarantor Subsidiaries”). All of the Guarantor Subsidiaries are 100% owned by the Company. Guarantor Subsidiaries will be automatically released from these guarantees upon the occurrence of certain events. International Debt Obligations The Company has two fixed rate, Euro denominated, international term loans for purposes of financing certain capital expenditures and general business needs. The first international term loan in the amount of $21.7 million was entered into on December 28, 2015, was fully funded during 2016 and has a term of six years, maturing December 28, 2021. As of December 31, 2020, $2.2 million remained outstanding on the first international term loan at a weighted average interest rate of 1.72%. The second international term loan in the amount of $12.8 million was entered into on December 21, 2018, bears interest at 1.96% and has a term of five years, maturing on December 31, 2023. As of December 31, 2020, $8.5 million remained outstanding on the second international term loan. The Company has two multicurrency international revolving credit facilities that are used for financing working capital and general business needs. The Company had $4.9 million of borrowings outstanding at a weighted average interest rate of 1.37% on the international revolving credit facilities as of December 31, 2020, leaving $11.2 million available for future borrowing. The terms of the international revolving credit facilities includes certain financial covenants, a guarantee of the international revolving credit facilities by the Company and a security agreement that includes collateralizing substantially all of the Quad Europe Sp. z.o.o. assets. The first multicurrency international revolving credit facility expires on October 31, 2021, and bears interest at the aggregate of the Warsaw Interbank Offered Rate (“WIBOR”) plus 1.40% for any Polish Zloty denominated borrowings, the aggregate of Euro Interbank Offered Rate (“EURIBOR”) plus 1.45% for any Euro denominated borrowings or the aggregate of British pound sterling LIBOR plus 1.45% for any British pound sterling denominate borrowings. The second multicurrency international revolving credit facility expires on November 20, 2021, and bears interest at the aggregate of WIBOR plus 1.00% for any Polish Zloty denominated borrowings or the aggregate of EURIBOR plus 1.00% for any Euro denominated borrowings. Fair Value of Debt Based upon the interest rates available to the Company for borrowings with similar terms and maturities, the fair value of the Company’s total debt was approximately $0.9 billion and $1.1 billion at December 31, 2020 and 2019, respectively. The fair value determination of the Company’s total debt was categorized as Level 2 in the fair value hierarchy (see Note 15, “Financial Instruments and Fair Value Measurements,” for the definition of Level 2 inputs). As of December 31, 2020, approximately $1.6 billion of the Company’s assets were pledged as security under various loans and other agreements.

The following limitations utilize a Total Net Leverage Ratio calculation, which, on a rolling twelve-month basis, is defined as consolidated net indebtedness to consolidated EBITDA (for the twelve months ended December 31, 2020, the Company’s Total Net Leverage Ratio was 3.30 to 1.00). • If the Company’s Total Net Leverage Ratio is greater than 2.75 to 1.00, the Company is prohibited from making greater than $60.0 million of annual dividend payments, capital stock repurchases and certain other payments. If the Total Net Leverage Ratio is less than 2.75 to 1.00, there are no such restrictions, provided, however, that no such restricted payments shall be made during the Covenant Relief Period. As the Company’s Total Net Leverage Ratio as of December 31, 2020, was 3.30 to 1.00, and we are in the Covenant Relief Period, the limitations described above are currently applicable. • If the Company’s Senior Secured Leverage Ratio is greater than 3.00 to 1.00 or the Company’s Total Net Leverage Ratio is greater than 3.50 to 1.00, the Company is prohibited from voluntarily prepaying any of the Senior Unsecured Notes and from voluntarily prepaying any other unsecured or subordinated indebtedness, with certain exceptions (including any mandatory prepayments on the Senior Unsecured Notes or any other unsecured or subordinated debt). If the Senior Secured Leverage Ratio is less than 3.00 to 1.00 and the Total Net Leverage Ratio is less than 3.50 to 1.00, there are no such restrictions. The limitations described above are currently not applicable, as the Company’s Senior Secured Leverage Ratio was 2.41 to 1.00 and Total Net Leverage Ratio was 3.30 to 1.00, as of December 31, 2020 . Estimated Principal Payments The approximate annual principal amounts due on long-term debt, excluding $6.9 million for future amortization of debt issuance costs, at December 31, 2020, were as follows: Principal Payments 2021 $ 20.7 2022 283.6 2023 87.2 2024 537.3 2025 1.0 2026 0.5 Total $ 930.3

Lease Obligations

Lease Obligations	Dec. 31, 2020
Leases [Abstract]
Lease Obligations	Leases The Company determines if an arrangement is or contains a lease at contract inception. The Company recognizes a right-of-use (“ROU”) asset and a lease liability at the lease commencement date. For operating and finance leases, the lease liability is initially measured at the present value of the unpaid lease payments at the lease commencement date, and is subsequently measured at amortized cost using the effective interest method. Key estimates and judgments include how the Company determines the discount rate, lease term and lease payments. • ASC 842 requires a lessee to discount its unpaid lease payments using the interest rate implicit in the lease or, if that rate cannot be readily determined, its incremental borrowing rate. Generally, the Company cannot determine the implicit interest rate as it does not have access to the lessor’s estimated residual value or the amount of the lessor’s deferred initial direct costs. Therefore, the Company generally uses its incremental borrowing rate as the discount rate for the lease. The Company’s incremental borrowing rate for a lease is the rate of interest it would have to pay on a collateralized basis to borrow an amount equal to the lease payments under similar terms based on the published United States Treasury rates as well as the Company’s credit rating at implementation or at the lease inception date. • The lease term for all of the Company’s leases includes the non-cancelable period of the lease, plus or minus any additional periods covered by an option to extend or terminate the lease that the Company is reasonably certain to exercise. • Lease payments included in the lease liability are comprised of fixed payments as well as any exercise price of a Company option to purchase the underlying asset if the Company is reasonably certain to exercise. The Company’s leases do not contain variable lease payments. ROU assets are initially measured at cost, which comprises the initial amount of the lease liability adjusted for lease payments made at or before the lease commencement date, plus any initial direct costs incurred less any lease incentives received. For operating leases, the ROU asset is subsequently amortized by the straight-line lease expense adjusted by the lease liability accretion over the lease term. For finance leases, the ROU asset is subsequently amortized on a straight-line basis from the lease commencement date to the earlier of the end of its useful life or the end of the lease term. Amortization of the ROU asset is recognized and presented separately from interest expense on the lease liability. The Company’s ROU assets for both operating and finance leases are reviewed for impairment losses on a quarterly basis in line with ASC 360-10 — Property, Plant, and Equipment — Overall. The Company has not recognized any impairment losses to date from continuing operations. The Company also monitors its leases for events or changes in circumstances that require a reassessment of the lease. When a reassessment results in the remeasurement of a lease liability, a corresponding adjustment is made to the carrying amount of the ROU asset. Operating leases are included in operating lease right-of-use assets—net, current portion of operating lease obligations, and operating lease obligations in the consolidated balance sheets. Finance leases are included in property and equipment—net, current portion of finance lease obligations, and finance lease obligations in the consolidated balance sheets. The Company has elected not to recognize ROU assets and lease liabilities for short-term leases that have an original lease term of twelve months or less. Therefore, the Company recognizes the lease payments associated with these short-term leases as an expense over the lease term in the consolidated statement of operations. Practical Expedients The Company has elected to apply the following practical expedients allowed under ASU 842: • The Company elected the practical expedient package and therefore did not reassess for any existing leases: ◦ whether contracts are or contain leases; ◦ the lease classification for any existing leases; and ◦ any initial direct costs. • The Company elected the practical expedient related to land easements, allowing to carry forward the accounting treatment for land easements on existing agreements. • The Company used “hindsight” judgments that impact the lease term. • The Company elected to combine lease and non-lease components into one lease component for select underlying lease asset categories. Real estate leases are accounted for separately while all other leases, primarily equipment leases, with separate lease and non-lease components are accounted for as a single lease component. Leases Financial Information The Company enters into various lease agreements for real estate, such as office space and manufacturing facilities, as well as equipment leases, including press, finishing and transportation equipment. Many of these leases provide the Company with options to renew, terminate, or in the case of equipment leases, purchase the related equipment at the termination value, as defined, and at various early buyout dates during the term of the lease. In general, the Company has determined these options were not reasonably certain to be exercised, and therefore are not included in the determination of the lease term. The following summarizes certain lease information for the years ended December 31, 2020 and 2019: Year Ended Year Ended December 31, 2020 December 31, 2019 Lease cost Finance lease cost: Amortization of right-of-use assets $ 3.6 $ 5.8 Interest on lease liabilities 0.4 1.0 Operating lease cost 32.6 42.6 Short-term lease cost 0.3 0.5 Sublease income (2.5) (3.1) Total lease cost $ 34.4 $ 46.8 Other information Cash paid for amounts included in the measurement of lease liabilities Operating cash flows from finance leases $ — $ — Operating cash flows from operating leases 33.4 43.0 Financing cash flows from finance leases 6.6 8.7 Right-of-use assets obtained in exchange for new finance lease liabilities 1.4 7.7 Right-of-use assets obtained in exchange for new operating lease liabilities 15.0 18.7 Weighted-average remaining lease term — finance leases 2.0 years 2.0 years Weighted-average remaining lease term — operating leases 4.0 years 5.1 years Weighted-average discount rate — finance leases 5.0 % 6.5 % Weighted-average discount rate — operating leases 6.3 % 6.7 % The components of finance lease assets at December 31, 2020 and 2019, were as follows: 2020 2019 Leased equipment—gross $ 26.1 $ 30.2 Less: accumulated depreciation (20.5) (17.8) Leased equipment—net $ 5.6 $ 12.4 Future maturities of lease liabilities at December 31, 2020, were as follows: Future Maturities of Operating Leases Future Maturities of Finance Leases 2021 $ 31.1 $ 2.9 2022 23.1 1.6 2023 16.6 0.4 2024 9.6 0.1 2025 6.8 0.1 2026 and thereafter 6.5 — Total minimum payments 93.7 5.1 Less: present value discount (10.8) (0.3) Present value of minimum payments 82.9 4.8 Less: current portion (28.4) (2.8) Long-term lease liability $ 54.5 $ 2.0

Income Taxes	Income Taxes Income taxes from continuing operations have been based on the following components of earnings (loss) from continuing operations before income taxes and equity in (earnings) loss of unconsolidated entity for the years ended December 31, 2020 and 2019: 2020 2019 United States $ (108.8) $ (94.1) Foreign 2.7 14.3 Total $ (106.1) $ (79.8) The components of income tax expense (benefit) from continuing operations for the years ended December 31, 2020, and 2019, were as follows: 2020 2019 Federal: Current $ (47.3) $ (2.2) Deferred 32.3 (21.0) State: Current (1.5) 0.9 Deferred 17.0 (4.9) Foreign: Current 0.6 0.1 Deferred (0.8) 2.7 Total income tax expense (benefit) $ 0.3 $ (24.4) The following table outlines the reconciliation of differences between the Federal statutory tax rate and the Company’s income tax expense (benefit) from continuing operations for the years ended December 31, 2020 and 2019: 2020 2019 Federal statutory rate $ (22.3) $ (16.8) State taxes, net of federal benefit 15.4 (4.1) Adjustment to valuation allowances 13.1 (0.2) Benefit of Net Operating Loss Carryback (14.3) — Impact from foreign branches 2.1 2.6 Adjustment of deferred tax liabilities 2.0 (1.6) Foreign rate differential (1.3) — Adjustment of uncertain tax positions 0.8 (2.5) Other 4.8 (1.8) Income tax expense (benefit) $ 0.3 $ (24.4) The $15.4 million effective rate reconciling item for State taxes, net of federal benefit, in 2020 includes a $19.1 million adjustment to valuation allowance primarily related to net operating losses and credits that are not expected to be realized in the future for state income tax purposes. The $13.1 million adjustment to valuation allowance in 2020 primarily relates to net operating losses, credits and the deferred tax asset for interest limitation that are not expected to be realized in the future for federal income tax purposes. On March 27, 2020, the United States government passed into law the Coronavirus Aid, Relief, and Economic Security Act (the “CARES act”). This legislation includes significant tax provisions and other measures to assist individuals and businesses impacted by the economic effects of the COVID-19 pandemic. The $14.3 million rate reconciling item for Benefit of Net Operating Loss Carryback in 2020, primarily relates to the provision from the CARES act allowing a net operating loss (“NOL”) generated in 2019 and 2020 to be carried back five years to years when the federal statutory tax rate was 35%. The amount of NOL available to be carried back was increased by other provisions in the CARES act that temporarily increases the amount of interest expense businesses are allowed to deduct in 2019 and 2020. Deferred Income Taxes The significant deferred tax assets and liabilities as of December 31, 2020 and 2019, were as follows: 2020 2019 Deferred tax assets: Net operating loss and other tax carryforwards $ 145.9 $ 125.1 Pension and workers compensation benefits 33.2 43.1 Accrued liabilities 20.5 11.1 Goodwill and intangible assets 19.0 17.4 Interest limitation 18.2 73.7 Accrued compensation 10.1 16.1 Allowance for doubtful accounts 7.2 5.5 Other 9.8 8.0 Total deferred tax assets 263.9 300.0 Valuation allowance (143.9) (107.1) Net deferred tax assets $ 120.0 $ 192.9 Deferred tax liabilities: Property, plant and equipment $ (103.8) $ (130.6) Other (4.2) (3.9) Total deferred tax liabilities (108.0) (134.5) Net deferred tax assets (liabilities) $ 12.0 $ 58.4 The Company has recorded deferred income tax liabilities of $4.2 million and $2.8 million as of December 31, 2020 and 2019, respectively, which were included in deferred income taxes in the consolidated balance sheets. The Company has also recorded deferred income tax assets of $16.2 million and $61.2 million as of December 31, 2020 and 2019, respectively, which were included in other long-term assets in the consolidated balance sheets. At December 31, 2020, the Company had the following gross amounts of tax-related carryforwards: • Net operating loss carryforwards of $82.2 million, $72.3 million and $638.3 million for federal, foreign and state, respectively. The federal net operating loss carryforward was generated in 2020 and is available without expiration. Of the foreign net operating loss carryforwards, $28.8 million is available without expiration, while the remainder expires through 2040. The state net operating loss carryforwards expire in varying amounts through 2040. • Capital loss carryforwards of $17.1 million and $8.7 million for federal and state, respectively. The federal and state capital loss carryforwards expire in 2022. • Various credit carryforwards of $8.9 million, $28.9 million and $44.0 million for federal, foreign and state, respectively. The federal carryforward expires in 2040, the foreign credit carryforward expires in 2026, and the state credit carryforwards include $32.1 million that is available without expiration, while the remainder expires through 2040. As of December 31, 2020, the Company has recorded a valuation allowance of $143.9 million on its consolidated balance sheet primarily related to the tax-affected amounts of the above carryforwards. The valuation allowance includes $22.5 million, $46.0 million and $75.4 million of federal, foreign and state deferred tax assets, respectively, that are not expected to be realized. Uncertain Tax Positions The following table summarizes the activity of the Company’s liability for unrecognized tax benefits at December 31, 2020 and 2019: 2020 2019 Balance at beginning of period $ 17.8 $ 14.4 Additions for tax positions of the current year — — Additions for tax positions of prior years 0.9 7.8 Reductions for tax positions of prior years (6.1) — Lapses of applicable statutes of limitations (1.0) (4.3) Settlements during the period — (0.1) Balance at end of period $ 11.6 $ 17.8 As of December 31, 2020, $10.4 million of unrecognized tax benefits would impact the Company’s effective tax rate, if recognized. Of that amount, it is reasonably possible that $0.4 million of the total amount of unrecognized tax benefits will decrease within the next twelve months due to resolution of income tax audits or statute expirations. The Company classified interest expense (income) and any related penalties (refunds) related to income tax uncertainties as a component of income tax expense (benefit). The following table summarizes the Company’s interest expense (income) related to tax uncertainties and penalties recognized during the years ended December 31, 2020 and 2019: 2020 2019 Interest expense (income) $ (0.3) $ 0.5 Penalties (refunds) — — Accrued interest and penalties related to income tax uncertainties are reported as components of other current liabilities and other long-term liabilities in the consolidated balance sheets.

Tax years from 2016 through 2020 remain open and subject to examination in the Company’s various major state jurisdictions within the United States.

Financial Instruments and Fair

Financial Instruments and Fair Value Measurements	12 Months Ended
Financial Instruments and Fair Value Measurements	Dec. 31, 2020
Fair Value Disclosures [Abstract]
Financial Instruments and Fair Value Measurements	Financial Instruments and Fair Value Measurements Certain assets and liabilities are required to be recorded at fair value on a recurring basis, while other assets and liabilities are recorded at fair value on a nonrecurring basis, generally as a result of acquisitions or impairment charges. Fair value is determined based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. GAAP also classifies the inputs used to measure fair value into the following hierarchy: Level 1: Quoted prices in active markets for identical assets or liabilities. Level 2: Quoted prices in active markets for similar assets or liabilities, 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. There were no Level 3 recurring measurements of assets or liabilities as of December 31, 2020. Interest Rate Swaps The Company currently holds two interest rate swap contracts. The purpose of entering into the contracts was to reduce the variability of cash flows from interest payments related to a portion of Quad’s variable-rate debt. The interest rate swaps were previously designated as cash flow hedges as they effectively converted the notional value of the Company’s variable rate debt based on one-month LIBOR to a fixed rate, including a spread on underlying debt, and a monthly reset in the variable interest rate. However, the Company amended its Senior Secured Credit Facility during the second quarter of 2020, which added a 0.75% LIBOR floor to the Company’s variable rate debt, changing the critical terms of the hedged instrument. Due to this change in critical terms, the Company has elected to de-designate the swaps as cash flow hedges, resulting in future changes in fair value being recognized in interest expense. The balance of the accumulated other comprehensive loss attributable to the interest rate swaps as of June 30, 2020, will be amortized to interest expense on a straight-line basis over the remaining lives of the swap contracts. The Company expects to reclassify $7.1 million of this balance to interest expense over the next twelve months. March 19, 2019 February 7, 2017 Effective date March 29, 2019 February 28, 2017 Termination date March 28, 2024 February 28, 2022 Term 5 years 5 years Notional amount $130.0 $250.0 Fixed swap rate 2.43% 1.89% The Company classifies the interest rate swaps as Level 2 because the inputs into the valuation model are observable or can be derived or corroborated utilizing observable market data at commonly quoted intervals. The fair values of the interest rate swaps classified as Level 2 as of December 31, 2020 and 2019, were as follows: Balance Sheet Location December 31, 2020 December 31, 2019 Interest rate swap liabilities Other long-term liabilities (14.4) (6.4) Prior to the Company’s de-designation of the interest rate swaps as cash flow hedges, the interest rate swaps were considered highly effective, with no amount of ineffectiveness recorded into earnings. The changes in the fair value of the interest rate swaps have been included in other comprehensive loss in the consolidated statements of comprehensive loss through the first quarter of 2020, and have been recorded as an adjustment to interest expense in the consolidated statements of operations in the periods thereafter. The cash flows associated with the interest rate swaps have been recognized as an adjustment to interest expense in the consolidated statements of operations: Year Ended December 31, 2020 2019 Cash Flow Impacts Net interest paid (received) $ 5.6 $ (0.8) Impacts with Swaps as Hedging Instruments Loss recognized in other comprehensive loss $ 11.1 $ 10.7 Impacts with Swaps as Nonhedging Instruments Income recognized in interest expense excluded from hedge effectiveness assessments $ (3.1) $ — Amounts reclassified out of accumulated other comprehensive loss to interest expense 3.6 — Net interest expense 5.6 (0.8) Total impact of swaps to interest expense $ 6.1 $ (0.8) Foreign Exchange Contracts The Company has operations in countries that have transactions outside their functional currencies and periodically enters into foreign exchange contracts. These contracts are used to hedge the net exposures of changes in foreign currency exchange rates and are designated as either cash flow hedges or fair value hedges. Gains or losses on net foreign currency hedges are intended to offset losses or gains on the underlying net exposures in an effort to reduce the earnings volatility resulting from fluctuating foreign currency exchange rates. There were no open foreign currency exchange contracts as of December 31, 2020. Natural Gas Forward Contracts The Company periodically enters into natural gas forward purchase contracts to hedge against increases in commodity costs. The Company’s commodity contracts qualified for the exception related to normal purchases and sales during the years ended December 31, 2020 and 2019, as the Company takes delivery in the normal course of business. Debt The Company measures fair value on its debt instruments using interest rates available to the Company for borrowings with similar terms and maturities and is categorized as Level 2. See Note 12, “Debt,” for the fair value of the Company’s debt as of December 31, 2020. Nonrecurring Fair Value Measurements In addition to assets and liabilities that are recorded at fair value on a recurring basis, the Company is required to record certain assets and liabilities at fair value on a nonrecurring basis, generally as a result of acquisitions or the remeasurement of assets resulting in impairment charges. See Note 3, “Acquisitions and Strategic Investments,” for further discussion on acquisitions. See Note 4, “Discontinued Operations”; Note 5, “Restructuring, Impairment and Transaction-Related Charges”; Note 6, “Goodwill and Other Intangible Assets”; and Note 9, “Property, Plant and Equipment” for further discussion on impairment charges recorded as a result of the remeasurement of certain long-lived assets. Other Estimated Fair Value Measurements The Company records the fair value of its forward contracts and pension plan assets on a recurring basis. The fair value of cash and cash equivalents, receivables, inventories, restricted cash, accounts payable and other current liabilities approximate their carrying values as of December 31, 2020 and 2019. See Note 16, “Employee Retirement Plans,” for the details of Level 1 and Level 2 inputs related to employee retirement plans.

Diversified Plan is comprised of participant-directed 401(k) contributions, Company match and profit sharing contributions, with total participant assets of $2.2 billion as of December 31, 2020. Company 401(k) matching contributions were $11.7 million and $15.4 million for the years ended December 31, 2020 and 2019, respectively. The Company’s ESOP holds profit sharing contributions of Company stock, which are made at the discretion of the Company’s Board of Directors. There were no profit sharing contributions for the years ended December 31, 2020 and 2019. Defined Benefit Plans The Company assumed various funded and unfunded frozen pension plans for a portion of its full-time employees in the United States as part of the acquisition of World Color Press in 2010. Benefits are generally based upon years of service and compensation. These plans are funded in conformity with the applicable government regulations. The Company funds at least the minimum amount required for all qualified plans using actuarial cost methods and assumptions acceptable under government regulations. The components of net pension income for the years ended December 31, 2020 and 2019, were as follows: Pension Benefits 2020 2019 Interest cost $ (13.6) $ (17.5) Expected return on plan assets 24.2 23.5 Net periodic benefit income 10.6 6.0 Settlement charge (0.1) — Net pension income $ 10.5 $ 6.0 The underfunded pension obligations are calculated using generally accepted actuarial methods and are measured annually as of December 31. The following table provides a reconciliation of the projected benefit obligation, fair value of plan assets and the funded status of the pension plans as of December 31, 2020 and 2019: Pension Benefits 2020 2019 Changes in benefit obligation Projected benefit obligation, beginning of year $ (515.7) $ (476.4) Interest cost (13.6) (17.5) Actuarial loss (40.5) (64.6) Benefits paid 43.6 42.8 Liability benefit from settlement 0.6 — Projected benefit obligation, end of year (525.6) (515.7) Changes in plan assets Fair value of plan assets, beginning of year 436.8 393.8 Actual return on plan assets 68.0 80.0 Employer contributions 7.8 5.8 Benefits paid (43.6) (42.8) Fair value of plan assets, end of year 469.0 436.8 Funded status $ (56.6) $ (78.9) The net underfunded defined benefit plan obligations decreased by $22.3 million during the year ended December 31, 2020. This decrease was primarily due to an actual return on pension plan assets of 17.0% during the year ended December 31, 2020, which was above the expected return on plan assets assumption of 5.75% and $7.8 million of employer contributions. The asset increase was partially offset by an 83 basis point decrease in the pension discount rate from 3.20% at December 31, 2019, to 2.37% at December 31, 2020. Amounts recognized on the consolidated balance sheets as of December 31, 2020 and 2019, were as follows: Pension Benefits 2020 2019 Current liabilities $ (1.7) $ (1.8) Noncurrent liabilities (54.9) (77.1) Total amount recognized $ (56.6) $ (78.9) The following table provides a reconciliation of the Company’s accumulated other comprehensive loss prior to any deferred tax effects at December 31, 2020 and 2019: Actuarial Gain / (Loss), net Balance at January 1, 2019 $ (33.3) Amount arising during the period (8.1) Balance at December 31, 2019 (41.4) Amount arising during the period 3.2 Impact of pension plan settlement charge included in net loss 0.1 Balance at December 31, 2020 $ (38.1) Actuarial gains and losses in excess of 10% of the greater of the projected benefit obligation or the market-related value of plan assets are recognized as a component of net periodic benefit costs over the average remaining service period of a plan’s active employees. Unrecognized prior service costs or credits are also recognized as a component of net periodic benefit cost over the average remaining service period of a plan’s active employees. The weighted average assumptions used to determine net periodic benefit costs for the years ended December 31, 2020 and 2019, were as follows: Pension Benefits 2020 2019 Discount rate 3.20 % 4.22 % Expected long-term return on plan assets 5.75 % 6.25 % The weighted average assumptions used to determine pension benefit obligations at December 31, 2020 and 2019, were as follows: Pension Benefits 2020 2019 Discount rate (end of year rate) 2.37 % 3.20 % The Company determines its assumed discount rate based on an index of high-quality corporate bond yields and matched-funding yield curve analysis as of the measurement date. Estimated Company Contributions and Benefit Payments In 2021, the Company expects to make cash contributions of $4.1 million to its qualified defined benefit pension plans and expects to make estimated benefit payments of $1.7 million to its non-qualified defined benefit pension plans. The actual pension contributions may differ based on the funding calculations, and the Company may choose to make additional discretionary contributions. The estimated benefit payments may differ based on actual experience. Estimated Future Benefit Payments by the Plans to or on Behalf of Plan Participants An estimate of the Plans’ present value of future benefit payments to be made from funded qualified plans and unfunded non-qualified plans to plan participants at December 31, 2020, were as follows: Future Pension 2021 $ 38.0 2022 36.1 2023 35.1 2024 34.1 2025 33.4 2026 - 2030 149.6 Thereafter 199.3 Total $ 525.6 Plan Assets and Investment Strategy The Company follows a disciplined investment strategy, which provides diversification of investments by asset class, foreign currency, sector and company. The Pension Committee has an approved investment policy for the pension plan that establishes long-term asset mix targets based on several factors including the following: the funded status, historical returns achieved by worldwide investment markets, the time horizon of the pension plan’s obligations, and the investment risk. An allocation range by asset class is developed whereby a mix of equity securities and debt securities are used to provide an appropriate risk-adjusted long-term return on plan assets. Third-party investment managers are employed to invest assets in both passively-indexed and actively-managed strategies and investment returns and risks are monitored on an ongoing basis. Derivatives are used at certain times to hedge foreign currency exposure. Gains or losses on the derivatives are offset by a corresponding change in the value of the hedged assets. Derivatives are strictly used for hedging purposes and not speculative purposes. The current target allocations for plan assets on a weighted average basis are 30% equity securities and 70% debt securities, including cash and cash equivalents. The actual asset allocation as of December 31, 2020, and as of December 31, 2019, was approximately 30% equity securities and 70% debt securities. Equity investments are diversified by country, issuer and industry sector. Debt securities primarily consist of government bonds and corporate bonds from diversified industries. The expected long-term rate of return on assets assumption is selected by first identifying the expected range of long-term rates of return for each major asset class. Expected long-term rates of return are developed based on long-term historical averages, current expectations of future returns and anticipated inflation rates. The expected long-term rate of return on plan assets is then calculated by weighting each asset class. The fair values of the Company’s pension plan assets at December 31, 2020 and 2019, by asset category were as follows: December 31, 2020 December 31, 2019 Asset Category Total Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Cash and cash equivalents $ 5.3 $ 5.3 $ — $ — $ 1.9 $ 1.9 $ — $ — Debt securities 125.7 — 125.7 — 118.0 — 118.0 — Equity securities 28.9 — 28.9 — 27.0 — 27.0 — Total pension plan assets, excluding those measured at net asset value (“NAV”) 159.9 $ 5.3 $ 154.6 $ — 146.9 $ 1.9 $ 145.0 $ — Investments measured at NAV (1) 309.1 289.9 Total pension plan assets $ 469.0 $ 436.8 ______________________________ (1) These investments consist of privately placed funds that are valued based on NAV. NAV of the funds is based on the fair value of each fund’s underlying investments. In accordance with ASC Subtopic 820-10, certain investments that are measured at fair value using the NAV per share (or its equivalent) practical expedient have not been classified in the fair value hierarchy. There were no Level 3 assets as of December 31, 2020 and 2019. See Note 15, “ Financial Instruments and Fair Value Measurements,” for definitions of fair value levels. The Company segregated its plan assets by the following major categories and levels for determining their fair value as of December 31, 2020: Cash and cash equivalents. Carrying value approximates fair value and these assets are classified as Level 1. Debt Securities. This category consists of bonds, short-term fixed income securities and fixed income pooled funds fair valued based on a compilation of primarily observable market information or broker quotes in over-the-counter markets and are classified as Level 2. Equity Securities. This category consists of equity pooled funds that are classified as Level 2 in the fair value hierarchy. Level 2 assets are valued using quoted prices in markets that are not active, broker dealer quotations, and other methods by which all significant input was observable at the measurement date. The valuation methodologies described above may generate a fair value calculation that may not be indicative of net realizable value or future fair values. While the Company believes the valuation methodologies used are appropriate, the use of different methodologies or assumptions in calculating fair value could result in different amounts. The Company invests in various assets in which valuation is determined by NAV. The Company believes that NAV is representative of fair value at the reporting date, as there are no significant restrictions on redemption on these investments or other reasons to indicate that the investment would be redeemed at an amount different than NAV. The fair value measurements in common/collective trusts, calculated using a NAV and their redemption restrictions, for the years ended December 31, 2020 and 2019, are as follows: Fair Value Redemption Frequency (If Currently Eligible) Redemption Notice Period 2020 2019 JP Morgan Chase Bank Strategic Property Fund $ 12.8 $ 12.6 Quarterly 30 days Pyramis Long Corporate A or Better 98.5 93.3 Daily 15 days Pyramis Long Duration 98.8 92.2 Daily 15 days Russell 3000 Index NL 99.0 91.8 Daily 1 day Total value of investments measured at NAV $ 309.1 $ 289.9 Risk Management For all directly invested funds, the concentration risk is monitored through specific guidelines in the investment manager mandates. The investment manager mandates were developed by the Company’s external investment advisor, and specify diversification standards such as the maximum exposure per issuer, and concentration limits per type of security, industry and country when applicable. For the investments made through pooled funds, the investment mandates of the funds were again reviewed by the Company’s external investment advisor, to determine that the investment objectives and guidelines were consistent with the Company’s overall pension plan risk management objectives. In managing the plan assets, management reviews and manages risk associated with funded status risk, interest rate risk, market risk, counterparty risk, liquidity risk and operational risk. Liability management and asset class diversification are central to the Company’s risk management approach and are integral to the overall investment strategy. Given the process in place to ensure a proper diversification of the portfolio, management believes that the Company pension plan assets are not exposed to significant concentration risk. Multiemployer Pension Plans The Company has previously participated in a number of MEPPs under terms of collective bargaining agreements that cover a number of its employees. The risks of participating in these MEPPs are different from single employer plans in the following aspects: • Assets contributed to the MEPPs by one company may be used to provide benefits to employees of other participating companies. • If a participating company stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating companies. • If the Company stops participating in some or all of its MEPPs, and continues in business, the Company would be required to pay an amount, referred to as a withdrawal liability, based on the unfunded status of the plan. The Company has withdrawn from all significant MEPPs and replaced these union sponsored “promise to pay in the future” defined benefit plans with a Company sponsored “pay as you go” defined contribution plan. The two MEPPs, the GCIU and GCC, are significantly underfunded, and will require the Company to pay a withdrawal liability to fund its pro rata share of the underfunding as of the plan year the full withdrawal was completed. As a result of the decision to withdraw, the Company accrued the estimated withdrawal liability based on information provided by each plan’s trustee, as part of the purchase price allocation for World Color Press. The GCIU Plan is a defined benefit plan that provides retirement benefits, total and permanent disability benefits, and pre-retirement death benefits for the participating union employees of the Company. The funded status of the GCIU Plan is classified as critical and declining based on the GCIU Plan’s 2020 certification to the United States Department of Labor, as the funded percentage for the plan is less than 65%, and the plan is projected to become insolvent in 2031. As a result, the GCIU Plan implemented a rehabilitation plan to improve the plan’s funded status. In 2019, the Company and the GCIU reached a settlement agreement for all claims, with scheduled payments until April 2032. The GCC Plan is a defined benefit plan that provides retirement benefits, disability benefits, and early retirement benefits for the participating union employees of the Company. The funded status of the GCC Plan is classified as critical and declining based on the GCC Plan’s 2020 certification to the United States Department of Labor, as the funded percentage for the plan is less than 65%, and the plan is projected to become insolvent by 2023. As a result, the GCC Plan implemented a rehabilitation plan to improve the plan’s funded status. In 2016, the Company and the GCC reached a settlement agreement for all claims, with scheduled payments until February 2024. The Company made payments totaling $11.4 million and $10.4 million for the years ended December 31, 2020 and 2019, respectively. The Company has reserved $35.7 million as its estimate of the total MEPPs withdrawal liability as of December 31, 2020, of which $32.2 million was recorded in other long-term liabilities and $3.5 million was recorded in other current liabilities in the consolidated balance sheets.

Earnings Per Share [Abstract]
Earnings Per Share Attributable to Quad Common Shareholders	Loss Per Share Attributable to Quad Common Shareholders Basic earnings (loss) per share attributable to Quad common shareholders is computed as net earnings (loss) attributable to Quad common shareholders, divided by the basic weighted average common shares outstanding. The calculation of diluted earnings (loss) per share attributable to Quad common shareholders includes the effect of any dilutive equity incentive instruments. The Company uses the treasury stock method to calculate the effect of outstanding dilutive equity incentive instruments, which requires the Company to compute total proceeds as the sum of the amount the employee must pay upon exercise of the award and the amount of unearned stock-based compensation costs attributed to future services. Equity incentive instruments for which the total employee proceeds from exercise exceed the average fair value of the same equity incentive instrument over the period have an anti-dilutive effect on earnings per share during periods with net earnings, and accordingly, the Company excludes them from the calculation. Due to the net loss incurred during the years ended December 31, 2020 and 2019, the assumed exercise of all equity incentive instruments was anti-dilutive and therefore, not included in the diluted loss per share calculation. Reconciliations of the numerator and the denominator of the basic and diluted per share computations for the Company’s common stock for the years ended December 31, 2020 and 2019, are summarized as follows: 2020 2019 Numerator: Net loss from continuing operations $ (106.6) $ (55.7) Less: net loss attributable to noncontrolling interests (0.2) — Net loss from continuing operations attributable to Quad common shareholders (106.4) (55.7) Loss from discontinued operations, net of tax (21.9) (100.6) Net loss attributable to Quad common shareholders $ (128.3) $ (156.3) Denominator: Basic weighted average number of common shares outstanding for all classes of common stock 50.6 50.0 Plus: effect of dilutive equity incentive instruments — — Diluted weighted average number of common shares outstanding for all classes of common shares 50.6 50.0 Loss per share attributable to Quad common shareholders: Basic and diluted: Continuing operations $ (2.10) $ (1.11) Discontinued operations (0.43) (2.01) Basic and diluted loss per share attributable to Quad common shareholders $ (2.53) $ (3.12) Cash dividends paid per common share for all classes of common shares $ 0.15 $ 1.05

Share-based Payment Arrangement [Abstract]
Equity Incentive Programs	Equity Incentive Programs The shareholders of the Company approved the Quad/Graphics, Inc. 2020 Omnibus Incentive Plan (the “2020 Plan”) at the Company’s annual meeting of shareholders held on May 18, 2020, (the “Annual Meeting”) for two complementary purposes: (1) to attract and retain outstanding individuals to serve as directors, officers and employees; and (2) to increase shareholder value. The Company’s previous plan, the Quad/Graphics, Inc. 2010 Omnibus Plan (the “2010 Plan”), was terminated on the date of approval of the 2020 Plan, and no new awards will be granted under the 2010 Plan. All awards that were granted under the 2010 Plan that were outstanding as of May 18, 2020, will remain outstanding and will continue to be governed by the 2010 Plan. The 2020 Plan provides for an aggregate 3,000,000 shares of class A common stock reserved for issuance, plus shares still available for issuance or re-credited under the 2010 Plan. Awards under the 2020 Plan may consist of incentive awards, stock options, stock appreciation rights, performance shares, performance share units, shares of class A common stock, restricted stock (“RS”), restricted stock units (“RSU”), deferred stock units (“DSU”) or other stock-based awards as determined by the Company’s Board of Directors. Each stock option granted has an exercise price of no less than 100% of the fair market value of the class A common stock on the date of grant. There were 3,580,483 shares of class A common stock reserved for issuance under the 2020 Plan as of December 31, 2020, including 3,000,000 shares of class A common stock that were approved for issuance at the Annual Meeting and 580,483 shares of class A common stock that were remaining and available for issuance that transferred from the 2010 Plan. Authorized unissued shares or treasury shares may be used for issuance under the Company’s equity incentive programs. The Company plans to either use treasury shares of its class A common stock or issue shares of class A common stock to meet the stock requirements of its awards in the future. The Company recognizes compensation expense based on estimated grant date fair values for all share-based awards issued to employees and non-employee directors, including stock options, performance shares, performance share units, restricted stock, restricted stock units and deferred stock units. The Company recognizes these compensation costs for only those awards expected to vest, on a straight-line basis over the requisite three four Equity Incentive Compensation Expense Equity incentive compensation expense was recorded primarily in selling, general and administrative expenses in the consolidated statements of operations and includes expense (income) recognized for liability awards that are remeasured on a quarterly basis. The total compensation expense recognized related to all equity incentive programs for the years ended December 31, 2020 and 2019, was as follows: Year ended December 31, 2020 2019 RS and RSU equity awards expense $ 9.7 $ 13.8 RSU liability awards income (0.1) (1.1) DSU awards expense 1.0 0.9 Total equity incentive compensation expense $ 10.6 $ 13.6 Total future compensation expense related to all equity incentive programs granted as of December 31, 2020, is estimated to be $9.3 million, which consists entirely of expense for RS and RSU awards. Estimated future compensation expense is $6.8 million for 2021, $2.3 million for 2022 and $0.2 million for 2023. Stock Options Options vest over four years, with no vesting in the first year and one-third vesting upon the second, third and fourth anniversary dates. As defined in the individual grant agreements, acceleration of vesting may occur under a change in control, death, disability or normal retirement of the grantee. Options expire no later than the tenth anniversary of the grant date, 24 months after termination for death, 36 months after termination for normal retirement or disability and 90 days after termination of employment for any other reason. Options are not credited with dividend declarations, except for the November 18, 2011 grants. Stock options are only to be granted to employees. There were no stock options granted during the years ended December 31, 2020 and 2019. There was no compensation expense recognized related to stock options for the years ended December 31, 2020 and 2019. There is no future compensation expense for stock options granted as of December 31, 2020. The following table is a summary of the stock option activity for the year ended December 31, 2020: Shares Weighted Weighted Aggregate Outstanding and exercisable at December 31, 2019 790,237 $ 25.27 1.1 $ — Granted — — Exercised — — Canceled/forfeited/expired (275,361) 21.11 Outstanding and exercisable at December 31, 2020 514,876 $ 27.49 0.5 $ — The intrinsic value of options outstanding and exercisable as of December 31, 2020 and 2019, was based on the fair value of the stock price. All outstanding options are vested as of December 31, 2020. There were no stock options exercised for the years ended December 31, 2020 and 2019. Restricted Stock and Restricted Stock Units Restricted stock and restricted stock unit awards consist of shares or the rights to shares of the Company’s class A stock which are awarded to employees of the Company. The awards are restricted such that they are subject to substantial risk of forfeiture and to restrictions on their sale or other transfer by the employee. RSU awards are typically granted to eligible employees outside of the United States. As defined in the individual grant agreements, acceleration of vesting may occur under a change in control, death, disability or normal retirement of the grantee. Grantees receiving RS grants are able to exercise full voting rights and receive full credit for dividends during the vesting period. All such dividends will be paid to the RS grantee within 45 days of full vesting. Grantees receiving RSUs are not entitled to vote but do earn dividends. Upon vesting, RSUs will be settled either through cash payment equal to the fair market value of the RSUs on the vesting date or through issuance of Company class A stock. The following table is a summary of RS and RSU award activity for the year ended December 31, 2020: Restricted Stock Restricted Stock Units Shares Weighted- Weighted- Units Weighted- Weighted- Nonvested at December 31, 2019 2,623,971 $ 17.82 1.5 230,621 $ 14.75 1.9 Granted 1,111,141 4.65 45,353 4.67 Vested (550,516) 26.84 (25,228) 26.88 Forfeited (222,846) 13.22 (1,208) 12.32 Nonvested at December 31, 2020 2,961,750 $ 11.55 1.3 249,538 $ 11.70 1.3 In the first quarter of 2019, the Company issued RSU awards in connection with the acquisition of Periscope that are accounted for as liability awards that will vest on March 1, 2022. The awards were recorded at fair value on the initial issuance date and are remeasured to fair value at each reporting period, with the change in fair value being recorded in selling, general and administrative expense in the consolidated statements of operations. The change in fair value of the awards classified as liabilities resulted in income of $0.1 million for the year ended December 31, 2020. As of December 31, 2020, the fair value of the RSU awards classified as liabilities was $0.5 million and was included in other long-term liabilities on the consolidated balance sheets. In general, RS and RSU awards will vest on the third anniversary of the grant date, provided the holder of the share is continuously employed by the Company until the vesting date. Compensation expense recognized for RS and RSUs classified as equity was $9.7 million and $13.8 million for the years ended December 31, 2020 and 2019, respectively. Deferred Stock Units Deferred stock units are awards of rights to shares of the Company’s class A stock and are awarded to non-employee directors of the Company. The following table is a summary of DSU award activity for the year ended December 31, 2020: Deferred Stock Units Units Weighted Average Grant Date Fair Value Per Share Outstanding at December 31, 2019 314,658 $ 16.22 Granted 204,088 4.67 Dividend equivalents granted 21,145 3.40 Settled (38,930) 19.81 Outstanding at December 31, 2020 500,961 $ 10.69 Each DSU award entitles the grantee to receive one share of class A stock upon the earlier of the separation date of the grantee or the second anniversary of the grant date, but could be subject to acceleration for a change in control, death or disability as defined in the individual DSU grant agreement. Grantees of DSU awards may not exercise voting rights, but are credited with dividend equivalents and those dividend equivalents will be converted into additional DSU awards based on the closing price of the class A stock. Compensation expense recognized for DSUs was $1.0 million and $0.9 million for the years ended December 31, 2020 and 2019, respectively. As DSU awards are fully vested on the grant date, all compensation expense was recognized at the date of grant.

The Company also has 0.5 million shares of $0.01 par value preferred stock authorized, of which none were issued at December 31, 2020 and 2019. The Company has no present plans to issue any preferred stock. On July 30, 2018, the Company’s Board of Directors authorized a share repurchase program of up to $100.0 million of the Company’s outstanding class A common stock. Under the authorization, share repurchases may be made at the Company’s discretion, from time to time, in the open market and/or in privately negotiated transactions as permitted by federal securities laws and other legal requirements. The timing, manner, price and amount of any repurchase will depend on economic and market conditions, share price, trading volume, applicable legal requirements and other factors. The program may be suspended or discontinued at any time. The Company is currently prohibited from repurchasing capital stock through the Covenant Relief Period, in accordance with the fourth amendment to the April 28, 2014 Senior Secured Credit Facility, completed on June 29, 2020. There were no shares of the Company’s class A stock repurchased during the years ended December 31, 2020 and 2019. As of December 31, 2020, there were $100.0 million of authorized repurchases remaining under the program.

New Accounting Pronouncements	New Accounting PronouncementsIn March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2020-04 “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (“ASU 2020-04”), which provides optional guidance for a limited period of time to ease the potential burden in accounting for reference rate reform. ASU 2020-04 permits entities to apply certain expedients and exceptions for contracts, hedging relationships, and other transactions impacted by the anticipated transition away from the use of LIBOR or other interbank offered rates to alternative reference rates. This optional guidance is effective as of March 12, 2020, through December 31, 2022. The Company is evaluating the impact of the adoption of ASU 2020-04 on the consolidated financial statements. In December 2019, the FASB issued Accounting Standards Update 2019-12 “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes” (“ASU 2019-12”), which enhances and simplifies various aspects of the income tax accounting guidance, including requirements such as tax basis step-up in goodwill obtained in a transaction that is not a business combination, ownership changes in investments, accounting for hybrid tax regimes, interim-period accounting for enacted changes in tax law and limitation of tax benefit on year-to-date losses. This guidance is effective for interim and annual periods beginning after December 15, 2020, with early adoption permitted. The Company has adopted this standard as of January 1, 2021. The Company evaluated the impact of the adoption of ASU 2019-12 on the consolidated financial statements and believes there is no material financial impact. In August 2018, the FASB issued Accounting Standards Update 2018-14 “Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans”, which adds, removes and clarifies year-end disclosure requirements related to defined benefit pension and other postretirement plans. This guidance is effective for annual periods ending after December 15, 2020, with early adoption permitted. This new guidance will require a retrospective adoption approach. The Company has adopted this standard for the year ended December 31, 2020, and has included the required disclosures within Note 16, “Employee Retirement Plans”.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations	Nature of Operations —As a worldwide marketing solutions partner, Quad leverages its 50-year heritage of platform excellence, innovation, strong culture and social purpose to create a better way for its clients, employees and communities. The Company’s integrated marketing platform helps brands and marketers reduce complexity, increase efficiency and enhance marketing spend effectiveness.

The Company operates primarily in the commercial print portion of the printing industry as a printer of retail inserts, publications, catalogs, special interest publications, journals, direct mail, directories, in-store marketing and promotion, packaging, newspapers, custom print products, other commercial and specialty printed products and global paper procurement. The Company’s products and services for a variety of industries are sold primarily throughout North America, South America and Europe. In addition, the Company strategically sources packaging product manufacturing over multiple end markets in Central America and Asia.
Principles of Consolidation and Basis of Presentation	Principles of Consolidation and Basis of Presentation —The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned and majority-owned controlled subsidiaries and have been prepared in accordance with GAAP. The results of operations and accounts of businesses acquired are included in the consolidated financial statements from the dates of acquisition (see Note 3, “Acquisitions and Strategic Investments”).
Foreign Operations	Foreign Operations—Assets and liabilities denominated in foreign currencies are translated into United States dollars at the exchange rate existing at the respective balance sheet dates. Income and expense items are translated at the average rates during the respective periods. Translation adjustments resulting from fluctuations in exchange rates are recorded as a separate component of accumulated other comprehensive income (loss) on the consolidated statements of shareholders’ equity, while transaction gains and losses are recorded in selling, general and administrative expenses on the consolidated statements of operations.
Use of Estimates	Use of Estimates —The preparation of consolidated financial statements requires the use of management’s estimates and assumptions that affect the reported assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from these estimates. Estimates are used when accounting for items and matters including, but not limited to: allowances for doubtful accounts, inventory obsolescence, asset valuations and useful lives, pension and postretirement benefits, self-insurance reserves, stock-based compensation, taxes, restructuring and other provisions and contingencies.
Revenue Recognition and Byproduct Recoveries	Revenue Recognition —The Company recognizes its products and services revenue based on when the transfer of control passes to the customer or when the service is completed and accepted by the customer. Under agreements with certain customers, products may be stored by the Company for future delivery. In these situations, the Company may receive warehouse management fees for the services it provides. Product returns are not significant because the products are customized; however, the Company accrues for the estimated amount of customer allowances at the time of sale based on historical experience and known trends. Revenue from services is recognized as services are performed. Revenues related to the Company’s imaging operations, which include digital content management, photography, color services and page production, are recognized in accordance with the terms of the contract, typically upon completion of the performed service and acceptance by the customer. Revenues related to the Company’s logistics operations, which includes the delivery of printed material, are recognized upon completion of services. Certain revenues earned by the Company require judgment to determine if revenue should be recorded gross as a principal or net of related costs as an agent. Billings for third-party shipping and handling costs, primarily in the Company’s logistics operations, and out-of-pocket expenses are recorded gross in net sales and cost of sales in the consolidated statements of operations. Many of the Company’s operations process materials, primarily paper, that may be supplied directly by customers or may be purchased by the Company and sold to customers. No revenue is recognized for customer-supplied paper. Revenues for Company-supplied paper are recognized on a gross basis. Byproduct Recoveries —The Company presents byproduct recoveries as a reduction of cost of sales–products in the consolidated statements of operations. Classification of byproduct recoveries as a reduction of cost of sales aligns the proceeds from byproduct recoveries with the corresponding manufacturing costs.
Financial Instruments	Financial Instruments —The Company uses derivative financial instruments for the purpose of hedging interest rate, commodity and foreign exchange exposures that exist as part of ongoing business operations, including interest rate swap agreements, natural gas forward purchase contracts and foreign exchange contracts. As a policy, the Company does not engage in speculative or leveraged transactions, nor does the Company hold or issue financial instruments for trading purposes. Derivative instruments are recorded on the consolidated balance sheets as either assets or liabilities measured at their fair value. If the derivative is designated as a fair value hedge, the changes in the fair value of the derivative and of the hedged item attributable to the hedged risk are recognized in earnings. If the derivative is designated as a cash flow hedge, the effective portion of the changes in the fair value of the derivative are recorded as a component of accumulated other comprehensive income (loss) and recognized in the consolidated statements of operations when the hedged item affects earnings. The ineffective portions of the changes in the fair value of hedges are insignificant and recognized in earnings. Cash flows from derivatives that are accounted for as cash flow or fair value hedges are included in the consolidated statements of cash flows in the same category as the item being hedged.
Fair Value Measurement	Fair Value Measurement—The Company applies fair value accounting for all assets and liabilities that are recognized or disclosed at fair value in its consolidated financial statements on a recurring basis. Fair value represents the amount that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities that are required to be recorded at fair value, the Company considers the principal or most advantageous market and the market-based risk measurements or assumptions that market participants would use in pricing the asset or liability.
Research and Development	Research and Development —Research and development costs related to the development of new products or the adaptation of existing products are expensed as incurred, included in cost of sales and totaled $3.0 million and $3.6 million during the years ended December 31, 2020 and 2019, respectively.
Cash and Cash Equivalents	Cash and Cash Equivalents and Restricted Cash —The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents.
Receivables	Receivables—Receivables are stated net of allowances for credit losses. No single customer comprised more than 5% of the Company’s consolidated net sales in 2020 or 2019, or 5% of the Company’s consolidated receivables as of December 31, 2020 or 2019.
Inventories	Inventories—Inventories include material, labor, and plant overhead and are stated at the lower of cost or net realizable value. At December 31, 2020 and 2019, all inventories were valued using the first-in, first-out method.
Property, Plant and Equipment	Property, Plant and Equipment —Property, plant and equipment are recorded at cost, and are depreciated over the estimated useful lives of the assets using the straight-line method for financial reporting purposes. See Note 9, “Property, Plant and Equipment,” for the components of the Company’s property, plant and equipment. Major improvements that extend the useful lives of existing assets are capitalized and charged to the asset accounts. Repairs and maintenance, which do not significantly improve or extend the useful lives of the respective assets, are expensed as incurred. Leasehold improvements are depreciated over the shorter of the lease term or the estimated useful life of the respective asset. When an asset is retired or disposed, the associated costs and accumulated depreciation are eliminated, and the resulting gain or loss is recognized in the Company’s consolidated statements of operations. Asset Category Range of Useful Lives Buildings 10 to 40 Years Machinery and equipment 3 to 15 Years Other 3 to 10 Years
Other Intangible Assets	Other Intangible Assets —Identifiable intangible assets are recognized apart from goodwill and are amortized over their estimated useful lives.
Impairment of Long-Lived and Other Intangible Assets	Impairment of Long-Lived and Other Intangible Assets —The Company evaluates long-lived assets and other intangible assets (of which the most significant are property, plant and equipment; right-of-use assets and customer relationship intangible assets) whenever events and circumstances have occurred that indicate the carrying value of an asset may not be recoverable. Determining whether impairment has occurred typically requires various estimates and assumptions, including determining which cash flows are directly related to the potentially impaired asset, the useful life over which cash flows will occur, their amount and the asset’s residual value, if any. In turn, assessing whether there is an impairment loss requires a determination of recoverability, which is generally estimated by the ability to recover the balance of the assets from expected future operating cash flows on an undiscounted basis. If impairment is determined to exist, any related impairment loss is calculated based on the difference in the fair value and carrying value of the asset.
Goodwill	Goodwill—Goodwill is reviewed annually for impairment as of October 31, or more frequently if events or changes in circumstances indicate that it is more likely than not that the fair value of a reporting unit is below its carrying value. In performing this analysis, the Company compares each reporting unit’s fair value to its carrying value. The fair value is estimated based on comparable company market valuations and/or expected future discounted cash flows to be generated by the reporting unit. If the carrying value exceeds the reporting unit’s fair value, an impairment loss would be charged to operations in the period identified.
Income Taxes	Income Taxes —The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of items reported in the financial statements. Under this method, deferred tax assets and liabilities are measured based on the differences between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the effective date of enactment. The Company records net deferred tax assets to the extent the Company believes these assets will more likely than not be realized. This determination is based upon all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies, and recent financial operations. If the Company determines that a deferred income tax asset will not be fully realized in the future, then a valuation allowance is established or increased to reflect the amount at which the asset will more likely than not be realized, which would increase the Company’s provision for income taxes. In a period after a valuation allowance has been established, if the Company determines the related deferred income tax assets will be realized in the future in excess of their net recorded amount, then an adjustment to reduce the related valuation allowance will be made, which would reduce the Company’s provision for income taxes. The Company is regularly audited by foreign and domestic tax authorities. These audits occasionally result in proposed assessments where the ultimate resolution might result in the Company owing additional taxes, including in some cases, penalties and interest. The Company recognizes a tax position in its consolidated financial statements when it is more likely than not that the position would be sustained upon examination by tax authorities. This recognized tax position is then measured at the largest amount of benefit that is more likely than not of being recognized upon ultimate settlement. The Company recognizes interest and penalties related to unrecognized tax benefits in income tax expense.
Pension Plans	Pension Plans —The Company assumed certain frozen underfunded defined benefit pension plans as part of the 2010 World Color Press acquisition. Pension plan costs are determined using actuarial methods and are funded through contributions. The Company records amounts relating to its pension plans based on calculations which include various actuarial assumptions including discount rates, assumed rates of return, and mortality. The Company reviews its actuarial assumptions on an annual basis and modifies the assumptions based on current rates and trends when it is appropriate to do so. The effects of modifications are recognized immediately on the consolidated balance sheets, but are generally amortized into operating income over future periods, with the deferred amount recorded in accumulated other comprehensive loss on the consolidated balance sheets. The Company believes that the assumptions utilized in recording its obligations under its plans are reasonable based on its experience, market conditions and input from its actuaries and investment advisors. For the purposes of calculating the expected return on plan assets, those assets are valued at fair value. When an event gives rise to both a curtailment and a settlement, the curtailment is accounted for prior to the settlement. The Company’s measurement date to measure the defined benefit plan assets and the projected benefit obligation is December 31. The Company has previously participated in MEPPs as a result of the acquisition of World Color Press. Due to the significant underfunded status of the MEPPs, the Company has withdrawn from all significant MEPPs and replaced these union sponsored “promise to pay in the future” defined benefit plans with a Company sponsored “pay as you go” defined contribution plan, which is the form of retirement benefit provided to Quad’s employees. As a result of the decision to withdraw, the Company recorded an estimated withdrawal liability for the MEPPs as part of the World Color
Stock-Based Compensation	Stock-Based Compensation—The Company recognizes stock-based compensation expense over the vesting period for all stock-based awards made to employees and directors based on the fair value of the instrument at the time of grant.
Accumulated Other Comprehensive Income (Loss)	Accumulated Other Comprehensive Income (Loss)—Accumulated other comprehensive income (loss) consists primarily of unrecognized actuarial gains and losses and prior service costs for pension plans, foreign currency translation adjustments and interest rate swap adjustments, and is presented in the consolidated statements of shareholders’ equity.
Fair Value Measurement Policy	Certain assets and liabilities are required to be recorded at fair value on a recurring basis, while other assets and liabilities are recorded at fair value on a nonrecurring basis, generally as a result of acquisitions or impairment charges. Fair value is determined based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants. GAAP also classifies the inputs used to measure fair value into the following hierarchy: Level 1: Quoted prices in active markets for identical assets or liabilities. Level 2: Quoted prices in active markets for similar assets or liabilities, 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. There were no Level 3 recurring measurements of assets or liabilities as of December 31, 2020.
Earnings (Loss) Per Share	Basic earnings (loss) per share attributable to Quad common shareholders is computed as net earnings (loss) attributable to Quad common shareholders, divided by the basic weighted average common shares outstanding. The calculation of diluted earnings (loss) per share attributable to Quad common shareholders includes the effect of any dilutive equity incentive instruments. The Company uses the treasury stock method to calculate the effect of outstanding dilutive equity incentive instruments, which requires the Company to compute total proceeds as the sum of the amount the employee must pay upon exercise of the award and the amount of unearned stock-based compensation costs attributed to future services.Equity incentive instruments for which the total employee proceeds from exercise exceed the average fair value of the same equity incentive instrument over the period have an anti-dilutive effect on earnings per share during periods with net earnings, and accordingly, the Company excludes them from the calculation.
New Accounting Pronouncements	In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2020-04 “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (“ASU 2020-04”), which provides optional guidance for a limited period of time to ease the potential burden in accounting for reference rate reform. ASU 2020-04 permits entities to apply certain expedients and exceptions for contracts, hedging relationships, and other transactions impacted by the anticipated transition away from the use of LIBOR or other interbank offered rates to alternative reference rates. This optional guidance is effective as of March 12, 2020, through December 31, 2022. The Company is evaluating the impact of the adoption of ASU 2020-04 on the consolidated financial statements. In December 2019, the FASB issued Accounting Standards Update 2019-12 “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes” (“ASU 2019-12”), which enhances and simplifies various aspects of the income tax accounting guidance, including requirements such as tax basis step-up in goodwill obtained in a transaction that is not a business combination, ownership changes in investments, accounting for hybrid tax regimes, interim-period accounting for enacted changes in tax law and limitation of tax benefit on year-to-date losses. This guidance is effective for interim and annual periods beginning after December 15, 2020, with early adoption permitted. The Company has adopted this standard as of January 1, 2021. The Company evaluated the impact of the adoption of ASU 2019-12 on the consolidated financial statements and believes there is no material financial impact. In August 2018, the FASB issued Accounting Standards Update 2018-14 “Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans”, which adds, removes and clarifies year-end disclosure requirements related to defined benefit pension and other postretirement plans. This guidance is effective for annual periods ending after December 15, 2020, with early adoption permitted. This new guidance will require a retrospective adoption approach. The Company has adopted this standard for the year ended December 31, 2020, and has included the required disclosures within Note 16, “Employee Retirement Plans”.

Disposal Groups, Including Discontinued Operations	The following table summarizes the results of operations of the Company’s Book business, which are included in the loss from discontinued operations in the consolidated statements of operations for the years ended December 31, 2020 and 2019. For The Year Ended December 31, 2020 2019 Total net sales $ 79.4 $ 213.8 Total cost of sales, excluding depreciation and amortization 80.4 226.8 Selling, general and administrative expenses 4.2 5.5 Depreciation and amortization — 13.6 Restructuring, impairment and transaction-related charges (1) 16.4 92.1 Goodwill impairment (2) — 10.1 Other expenses, net 0.3 0.1 Loss from discontinued operations before income taxes (21.9) (134.4) Income tax benefit — (33.8) Loss from discontinued operations, net of tax $ (21.9) $ (100.6) ______________________________ (1) The Company recognized $11.5 million of impairment charges for tangible property, plant and equipment during the year ended December 31, 2020, to reduce the carrying value of the Book business to its fair value, and recognized $2.2 million in employee termination charges and $2.7 million in other restructuring charges during the year ended December 31, 2020. Impairment charges recognized to reduce the carrying value of the Book business to its fair value during during the year ended December 31, 2019 included: $86.5 million of impairment charges for tangible property, plant and equipment and $5.6 million of impairment charges for contract assets. (2) The Book business was included in the Core Print and Related Services reporting unit. The amount of goodwill allocated to the Book business was determined based on the relative fair value of the Book business and the portion of the reporting unit that will be retained. Due to the decision to sell the Book business, the Company must determine whether any of the assets of the Book business were impaired.
