Accounting Policies [Abstract]

Basis of Presentation and Summary of Significant Accounting Policies

Note 1. Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation —The accompanying consolidated financial statements include the accounts of R. R. Donnelley & Sons Company and its subsidiaries (the “Company” or “RRD”) and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). All intercompany transactions have been eliminated in consolidation.

Nature of Operations —RRD is a global, integrated communications provider enabling organizations to create, manage, deliver and optimize their multichannel marketing and business communications. We have a flexible and comprehensive portfolio of integrated communications solutions that allows our clients to engage audiences, reduce costs and drive revenues. Our innovative content management offering, production platform, supply chain management, outsourcing capabilities and customized consultative expertise assist our clients in the delivery of integrated messages across multiple media to highly targeted audiences at optimal times for clients in virtually every private and public sector.

Use of Estimates —The preparation of consolidated financial statements, in conformity with GAAP, requires the extensive use of management’s estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the 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, allowance for credit losses, inventory obsolescence, asset valuations and useful lives, employee benefits, self-insurance reserves, taxes, restructuring and other provisions and contingencies.

Foreign Operations —Assets and liabilities denominated in foreign currencies are translated into U.S. dollars at the exchange rates 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 other comprehensive income (loss) while transaction gains and losses are recorded in net income (loss). Deferred taxes are not provided on cumulative foreign currency translation adjustments when we expect foreign earnings to be permanently reinvested.

Fair Value Measurements —Certain assets and liabilities are required to be recorded at fair value on a recurring basis. 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. We record the fair value of our foreign currency contracts, available-for-sale securities, interest rate swaps, pension plan assets and other postretirement benefits (“OPEB”) plan assets on a recurring basis. Assets measured at fair value on a nonrecurring basis include long-lived assets held and used, long-lived assets held for sale, goodwill and other intangible assets. The fair value of cash, cash equivalents, restricted cash, accounts receivable, short-term debt and accounts payable approximate their carrying values. The three-tier value hierarchy, which prioritizes valuation methodologies based on the reliability of the inputs, is:

Level 1 —Valuations based on quoted prices for identical assets and liabilities in active markets.

Level 2 —Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data.

Level 3 —Valuations based on unobservable inputs reflecting our own assumptions, consistent with reasonably available assumptions made by other market participants.

Net Sales - We have historically presented Sales and Cost of Sales for products and services separately in the Consolidated Statement of Operations and related disclosures. Sales from services became immaterial in relation to Net Sales in the third quarter of 2020 when adjusted by the effect of the activity of the Logistics business now presented in discontinued operations. Accordingly, we now present sales from products and services together within Net Sales in the Consolidated Statement of Operations and related disclosures. Refer to Note 18 – Segment and Geographic Area Information for further details.

Cash, Cash Equivalents and Restricted Cash

Cash and cash equivalents —We consider all highly liquid investments with original maturities of three months or less to be cash equivalents. Short-term securities consist of investment grade instruments of governments, financial institutions and corporations.

Restricted cash —Restricted cash primarily includes amounts related to letters of credit and bank acceptance drafts and amounts received in escrow in connection with the sale of DLS Worldwide (Refer to Note 2 – Discontinued Operations in the Consolidated Financial Statements).

The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the Consolidated Balance Sheets that sum to the total of the same such amounts shown in the Consolidated Statement of Cash Flows.

	December 31,
	2020		2019
Cash and cash equivalents	$	288.8	$	191.9
Restricted cash - current^(a)		62.6		32.9
Restricted cash - noncurrent^(b)		6.2		0.1
Total cash, cash equivalents and restricted cash	$	357.6	$	224.9

(a)	Included within Prepaid expenses and other current assets within the Consolidated Balance Sheets.

(b)	Included within Other noncurrent assets within the Consolidated Balance Sheets.

Receivables and Allowance for Credit Losses —Receivables are stated net of allowances for credit losses and primarily include trade receivables, notes receivable and miscellaneous receivables from suppliers. No single client comprised more than 10% of our consolidated net sales in 2020, 2019 or 2018. We recognize an allowance for credit losses for financial assets carried at amortized cost to present the net amount expected to be collected as of the balance sheet date. Such allowance is based on credit losses expected to arise over the life of the asset’s contractual term, which includes consideration of prepayments. Assets are written off when we determine that such financial assets are deemed uncollectible and are recognized as a deduction from the allowance for credit losses. Expected recoveries of amounts previously written off, not to exceed the aggregate of the amount previously written off, are included in determining the necessary reserve at the balance sheet date. We pool financial assets based on similar risk characteristics to estimate expected credit losses. We estimate expected credit losses on financial assets individually when those assets do not share similar risk characteristics. We closely monitor our accounts receivable including timely account reconciliations, detailed reviews of past due accounts, updated credit limits, and monthly analysis of the adequacy of our reserve for credit losses. Specific client provisions are made when a review of significant outstanding amounts, utilizing information about client creditworthiness and current economic trends, indicates that collection is doubtful. In addition, provisions are made at differing rates, based upon the age of the receivable and our historical collection experience.

We utilize a loss rate approach to determine lifetime expected credit losses for our financial assets. This method is used for calculating an estimate of losses based primarily on our historical loss experience. In determining loss rates, we evaluate information related to historical losses, adjusted for current conditions and further adjusted for the period of time that we can reasonably forecast. We have concluded that we can reasonably support a forecast period for the contractual life of our financial assets. Qualitative and quantitative adjustments related to current conditions and the reasonable and supportable forecast period consider the following: the customer or vendor’s creditworthiness, changes in our policy and procedures to establish customer credit limits, changes in the payment terms of receivables, existence and effect of any concentration of credit and changes in the level of such concentrations, and the effects of other external forces such as the current and forecasted direction of the economic and business environment. We have considered the current and expected economic and market conditions as a result of COVID-19 in determining credit loss expense for the period ended December 31, 2020.

Transactions affecting the allowance for credit losses for financial instruments during the years ended December 31, 2020 and 2019 were as follows. Recoveries were immaterial for the years ended December 31, 2020 and 2019.

	2020			2019
Balance, beginning of year	$	14.3		$	19.6
Additional allowance recognized due to adoption of Topic ASC 326		0.3			—
Credit loss expense		5.7			3.3
Write-offs and other		(4.4	)		(8.6	)
Balance, end of year	$	15.9		$	14.3

Inventories —Inventories include material, labor and factory overhead and are stated at the lower of cost or market and net of excess and obsolescence reserves for raw materials and finished goods. Provisions for excess and obsolete inventories are made at differing rates, utilizing historical data and current economic trends, based upon the age and type of the inventory. Specific excess and obsolescence provisions are also made when a review of specific balances indicates that the inventories will not be utilized in production or sold. The cost of 36.6% and 37.9% of the inventories at December 31, 2020 and 2019, respectively, has been determined using the Last-In, First-Out (LIFO) method. This method is intended to reflect the effect of inventory replacement costs within results of operations; accordingly, charges to cost of sales generally reflect recent costs of material, labor and factory overhead. We use an external-index method of valuing LIFO inventories. The remaining inventories, primarily related to certain acquired and international operations, are valued using the First-In, First-Out or specific identification methods.

The components of inventories, net of excess and obsolescence reserves for raw materials and finished goods, at December 31, 2020 and 2019 were as follows:

	2020			2019
Raw materials and manufacturing supplies	$	147.3		$	139.4
Work in process		64.8			64.6
Finished goods		107.9			116.4
LIFO reserve		(17.9	)		(18.6	)
Total	$	302.1		$	301.8

Long-Lived Assets —We assess potential impairments to our long-lived assets if events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. An impaired asset is written down to its estimated fair value based upon the most recent information available. Estimated fair value is generally measured by discounting estimated future cash flows. Long-lived assets, other than goodwill and other intangible assets, which are held for sale, are recorded at the lower of the carrying value or the fair value less the estimated cost to sell.

Property, Plant and Equipment —Property, plant and equipment are recorded at cost and depreciated on a straight-line basis over their estimated useful lives. Useful lives range from 15 to 40 years for buildings, the lesser of 7 years or the lease term for leasehold improvements and generally from 3 to 15 years for machinery and equipment. Maintenance and repair costs are charged to expense as incurred. Major overhauls that extend the useful lives of existing assets are capitalized. When properties are retired or disposed, the costs and accumulated depreciation are eliminated and the resulting profit or loss is recognized in the results of operations.

The components of property, plant and equipment at December 31, 2020 and 2019 were as follows:

	2020			2019
Land	$	38.2		$	47.8
Buildings		361.0			379.5

During the years ended December 31, 2020, 2019 and 2018, depreciation expense was $100.8 million, $115.5 million, and $125.2 million, respectively.

During the fourth quarter of 2017, we entered into an agreement to sell a printing facility in Shenzhen, China and transfer the related land use rights. As of December 31, 2020, we have received deposits in accordance with the terms of the agreement of approximately $123.3 million which is recorded in other noncurrent liabilities on the Consolidated Balance Sheets. As of December 31, 2020, the carrying cost of the building and land use rights is recorded in other noncurrent assets and is not material. Additional deposits will be paid to us in accordance with the agreement. Gross proceeds from the sale are expected to be approximately $250.0 million, subject to changes in the exchange rate, and we expect the transaction to close in 2022 after closing conditions are satisfied and government approvals are obtained. Our contract with the buyer requires them to pay the final installment in 2022 even if the government’s approval is further delayed. If the buyer fails to comply with terms of the agreement or terminates for any reason, the Company is entitled to retain 30% of the purchase price as liquidated damages.

Goodwill —Goodwill is reviewed for impairment annually 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.

For certain reporting units, we may perform a qualitative, rather than quantitative, assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. In performing this qualitative analysis, we consider various factors, including the excess of prior year estimates of fair value compared to carrying value, the effect of market or industry changes and the reporting units’ actual results compared to projected results. Based on this qualitative analysis, if we determine that it is more likely than not that the fair value of the reporting unit is greater than its carrying value, no further impairment testing is performed.

For the remaining reporting units, we compare each reporting unit’s fair value, estimated based on comparable company market valuations and expected future discounted cash flows to be generated by the reporting unit, to its carrying value. See Note 6, Goodwill and Other Intangible Assets, for further discussion.

Amortization —Certain costs to acquire and develop internal-use computer software are capitalized and amortized over their estimated useful life using the straight-line method, up to a maximum of five years. Amortization expense, primarily related to internally-developed software and excluding amortization expense related to other intangible assets, was $26.1 million, $29.4 million and $27.4 million for the years ended December 31, 2020, 2019 and 2018, respectively. Deferred debt issuance costs are amortized over the term of the related debt. Other intangible assets are recognized separately from goodwill and are amortized over their estimated useful lives. See Note 6, Goodwill and Other Intangible Assets, for further discussion of other intangible assets and the related amortization expense.

Financial Instruments —We use derivative financial instruments to hedge exposures to foreign exchange fluctuations in the ordinary course of business and to hedge the interest rate exposure on certain floating-rate debt.

All derivatives are recorded as other current or noncurrent assets or other current or noncurrent liabilities on the balance sheet at their respective fair values with unrealized gains and losses recorded in other comprehensive income (loss), net of applicable income taxes, or in the results of operations, depending on the purpose for which the derivative is held. For derivatives designated and that qualify as fair value hedges, the gain or loss on the derivative, as well as the offsetting gain or loss on the hedged item attributable to the hedged risk, are recognized in the results of operations. Changes in the fair value of derivatives that do not meet the criteria for designation as a hedge at inception, or fail to meet the criteria thereafter, are recognized currently in the results of operations. At inception of a hedge transaction, we formally document the hedge relationship and the risk management objective for undertaking the hedge. In addition, we assess, both at inception of the hedge and on an ongoing basis, whether the derivative in the hedging transaction has been highly effective in offsetting changes in fair value of the hedged item and whether the derivative is expected to continue to be highly effective. The impact of any ineffectiveness is recognized currently in the results of operations.

Our foreign currency contracts and interest rate swaps are subject to master netting agreements that allow us to settle positive and negative positions with the respective counterparties. Under these master netting agreements, net settlement generally permits us or the counterparty to determine the net amount payable for contracts due on the same date and in the same currency for similar types of derivative transactions. The master netting agreements generally also provide for net settlement of all outstanding contracts with a counterparty in the case of an event of default or a termination event. See Note 13, Derivatives, for additional information.

Share-Based Compensation —We recognize share-based compensation expense based on estimated fair values for all share-based awards made to employees and directors, including stock options, restricted stock units and performance share units. We recognize compensation expense for share-based awards expected to vest on a straight-line basis over the requisite service period of the award based on their grant date fair value. See Note 16, Stock and Incentive Programs for Employees and Directors, for further discussion.

Preferred Stock —We have two million shares of $1.00 par value preferred stock authorized for issuance. The Board of Directors may divide the preferred stock into one or more series and fix the redemption, dividend, voting, conversion, sinking fund, liquidation and other rights. We have no present plans to issue any preferred stock. We have reserved 0.2 million preferred stock shares for issuance under the Stockholder Rights Plan discussed in Note 17.

Pension and OPEB Plans —We record annual income and expense amounts relating to our pension and OPEB plans based on calculations which include various actuarial assumptions, including discount rates, mortality, assumed rates of return, compensation increases, turnover rates and healthcare cost trend rates. We review our actuarial assumptions on an annual basis and make modifications to the assumptions based on current rates and trends when it is deemed appropriate to do so. The effect of modifications on the value of plan obligations and assets is recognized immediately within other comprehensive income (loss) and amortized into operating earnings over future periods. We believe that the assumptions utilized in recording our obligations under our plans are reasonable based on our experience, market conditions and input from our actuaries and investment advisors. See Note 10, Retirement Plans, for additional information.

Taxes on Income —Deferred taxes are provided using an asset and liability method whereby deferred tax assets are recognized for deductible temporary differences and operating loss carryforwards and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax basis. Deferred tax assets are reduced by a valuation allowance when, in our opinion, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment.

We recognize deferred tax liabilities related to taxes on certain foreign earnings that were not considered to be permanently reinvested. No deferred tax liabilities were recognized for foreign earnings that were considered to be permanently reinvested. We regularly evaluate whether foreign earnings are expected to be permanently reinvested. This evaluation requires judgment about our future operating and liquidity needs. Changes in economic and business conditions, foreign or U.S. tax laws, or our financial situation could result in changes to these judgments and the need to record additional tax liabilities.

We are regularly audited by foreign and domestic tax authorities. These audits occasionally result in proposed assessments where the ultimate resolution might result in us owing additional taxes, including in some cases, penalties and interest. We recognize a tax position in our financial statements when it is more likely than not (i.e., a likelihood of more than fifty percent) 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 greater than fifty percent likely of being realized upon ultimate settlement. Although we believe that our estimates are reasonable, the final outcome of uncertain tax positions may be materially different from that which is reflected in our financial statements. We adjust such reserves upon changes in circumstances that would cause a change to the estimate of the ultimate liability, upon effective settlement or upon the expiration of the statute of limitations, in the period in which such event occurs. See Note 11, Income Taxes, for further discussion.

Spinoff Transactions —On October 1, 2016, we completed the separation of our financial communications and data services business (“Donnelley Financial Solutions, Inc.” or “Donnelley Financial”) and the publishing and retail-centric print services and office products business (“LSC Communications, Inc.” or “LSC”) into two separate publicly-traded companies (the "Separation"). We completed the tax-free distribution of 80.75% of the outstanding common stock of each Donnelley Financial and LSC to our stockholders of record on September 23, 2016 who received one share of Donnelley Financial and LSC for every eight shares of RRD common stock held as of the record date (the “Distribution”). We originally retained 19.25% of the outstanding common stock of each Donnelley Financial and LSC, but disposed of our retained investment in those businesses in subsequent transactions.

The Distribution was recorded as a reduction in Stockholder's Equity during the fourth quarter of 2016. During the second quarter of 2019, we identified an error in the accounting for the Distribution. As a result, the error, which was determined by management to be immaterial to the previously issued consolidated financial statements, has been corrected by increasing Accumulated Deficit by $12.0 million during the year ended December 31, 2019.

Discontinued Operations And Disposal Groups [Abstract]

Discontinued Operations

Note 2. Discontinued Operations

On November 2, 2020, we sold DLS Worldwide, which was part of our broader Logistics business and a component of the Business Services reporting segment for $225.0 million cash, subject to a customary working capital adjustment and an escrow of $22.5 million. We entered into a transaction support agreement with the buyer to assist them in the transition of certain functions, including, but not limited to, information technology, finance, and HR. Further, we entered into several commercial agreements whereby we continue to receive logistics services from the divested business. Sales from the Logistics business to RRD previously eliminated in consolidation have been recast and are now shown as external sales within the financial results of discontinued operations below. The net sales were $38.7 million, $62.7 million and $106.0 million respectively for the twelve months ended December 31, 2020, 2019 and 2018.

On November 3, 2020 we sold International Logistics, also a portion of our broader Logistics business and a component of the Business Services reporting segment for $13.0 million cash, subject to a customary working capital adjustment.

The sale of these businesses is part of our strategy to exit non-core businesses in order to pursue portfolio optimization and to reduce debt. As part of this strategic shift, we previously sold Print Logistics in July 2018 and Courier Logistics in March 2020.

The after-tax net gain on sale of discontinued operations of $127.4 million for the period ended December 31, 2020 reflects the net gain on sale of DLS Worldwide, Courier, and International Logistics.

Beginning in the third quarter of 2020, we have reflected the Print Logistics business, the Logistics Courier business, the DLS Worldwide business, and the International Logistics business, as discontinued operations for all periods presented in the Consolidated Statements of Operations.

Results of discontinued operations were as follows:

	Twelve Months Ended
	December 31,
	2020			2019			2018
Net sales	$	632.5		$	865.7		$	1,203.8
Cost of sales		(548.6	)		(758.7	)		(1,070.5	)
Selling, general, administrative and other operating expenses		(66.2	)		(95.1	)		(109.6	)
Restructuring, impairment and other expense		(21.1	)		(98.6	)		(0.2	)
Operating income (loss) from discontinued operations		(3.4	)		(86.7	)		23.5
Income tax expense		(0.9	)		1.7			3.2
Net income (loss) from discontinued operations	$	(2.5	)	$	(88.4	)	$	20.3

Restructuring, impairment, and other expenses included $20.6 million and $98.5 million of non-cash charges related to impairment of goodwill recorded in 2020 and 2019 respectively.

Our evaluation of goodwill for impairment involves the comparison of the fair value of each reporting unit to its carrying value. If the carrying value of a reporting unit exceeds its estimated fair value, an impairment loss is recognized equal to the excess, limited to the total amount of goodwill allocated to that reporting unit. The Company determines the fair value of its reporting units using a combination of comparable company market valuations and expected future discounted cash flows.

During the first quarter of 2020, we identified a triggering event at our Logistics reporting unit. We determined that the fair value of our Logistics reporting unit was lower than its carrying value, resulting in a goodwill impairment charge of $20.6 million. The goodwill impairment charge resulted from reductions in the estimated fair value for this reporting unit based on lower expectations for future revenue, profitability and cash flows driven by expected reduced demand due to the COVID-19 pandemic. The goodwill impairment charge was determined using discounted cash flow analysis and comparable marketplace fair value data which utilized Level 3 inputs including forecasted future revenue and the selection of the discount rate.

Assets and liabilities of discontinued operations presented in the Consolidated Balance Sheets as of December 31, 2019 include the following:

	December 31, 2019
Receivables, net of allowance	$	120.6
Operating lease right-of-use assets		8.8
Goodwill		53.3
Intangible assets, net		10.9
Other assets		7.0
Total assets of discontinued operations	$	200.6


Accounts payable	$	53.3
Accrued expenses and other liabilities		38.8
Total liabilities of discontinued operations	$	92.1

Note 3. Dispositions

2019 Dispositions

On October 25, 2019, we completed the sale of substantially all of the Global Document Solutions (“GDS”) business for approximately $53.7 million. GDS primarily provided statements and print management services in Europe. The disposition resulted in a loss of $3.8 million during 2019, which was recorded in Other operating expense (income) in the Consolidated Statements of Operations.

On May 8, 2019, we sold the R&D business within the Business Services segment for net proceeds of $11.6 million. The disposition resulted in a gain of $6.1 million during 2019, which was recorded in Other operating expense (income) in the Consolidated Statements of Operations.

On March 31, 2019, our subsidiary, RR Donnelley Editora e Grafica Ltda. (“RRD Brazil”), filed for bankruptcy liquidation in bankruptcy court in Brazil. The bankruptcy petition was approved by the court shortly thereafter and a bankruptcy trustee was appointed. As a result of the bankruptcy liquidation, we recorded a gain of $4.0 million in Other operating expense (income) during 2019, primarily reflecting the reclassification of cumulative currency translation adjustments into earnings and ongoing expenses associated with the bankruptcy proceedings. Subsequent to March 31, 2019, the operating results of RRD Brazil are no longer included in our consolidated results of operations except for legal fees associated with the bankruptcy proceedings. The operations of RRD Brazil had been included in the Business Services segment.

Note 4. Revenue Recognition

All revenue recognized in the Consolidated Statements of Operations is considered to be revenue from contracts with clients according to Subtopic 606, which we adopted on January 1, 2018.

Disaggregation of Revenue

The following table presents net sales disaggregated by products and services:

	2020		2019		2018
Commercial print	$	1,357.7	$	1,694.5	$	1,935.6

Digital and creative solutions		100.0		111.7		125.1
Total net sales	$	4,766.3	$	5,473.2	$	5,702.4

Revenue for commercial print, direct marketing, packaging, statements, labels, digital print and fulfillment, supply chain management and forms is primarily recognized at a point in time. We generally recognize revenue for these products upon the transfer of control of the products to the client which typically occurs upon transfer of title and risk of ownership, which is generally upon shipment to the client. For certain products, we are able to recognize revenue for completed inventory billed but not yet shipped at the client’s direction. Revenue for business process outsourcing and digital and creative solutions is recognized over time or at a point in time, depending on the nature of the service which could be either recurring or project-based.

The following is a description of our products and services:

Commercial Print

We generate revenue by providing various commercial printing products and offer a full range of branded materials including manuals, publications, brochures, business cards, flyers, post cards, posters and promotional items.

Direct Marketing

We generate revenue by providing audience segmentation, creative development, program testing, print production, postal optimization and performance analytics for large-scale personalized direct mail programs.

Packaging

We generate revenue by providing packaging solutions, ranging from rigid boxes to in-box print materials, for clients in healthcare and life sciences, consumer electronics, cosmetics and consumer packaged goods industries.

Statements

We generate revenue by creating critical business communications, including customer billings, financial statements, healthcare communications and insurance documents. Our capabilities include design and composition, variable imaging, email, archival and digital mail interaction, as well as our innovative RRDigital solution set.

Labels

We generate revenue by producing custom labels for clients across multiple industries including warehouse and distribution, retail, pharmaceutical, manufacturing and consumer packaging. We offer distribution and shipping labels, healthcare and durable goods labels, promotional labels and consumer product goods packaging labels.

Digital Print and Fulfillment

We generate revenue by providing in-store marketing materials, including signage and point-of-purchase materials, as well as custom marketing kits that require multiple types of marketing collateral. Under the trade name Motif^TM, we also create custom photobooks.

Supply Chain Management

We generate revenue by providing workflow design to assembly, configuration, kitting and fulfillment for clients in life sciences and healthcare, consumer electronics, telecommunications, cosmetics, education and industrial industries.

Forms

We generate revenue by producing a variety of forms including invoices, order forms and business forms that support both the private and public sectors for clients in financial, government, retail, healthcare and business services industries.

Business Process Outsourcing

We generate revenue by providing outsourcing services including creative services, research and analytics, financial management and other services for legal providers, insurance, telecommunications, utilities, retail and financial services companies.

Digital and Creative Solutions

We generate revenue by creating and managing content for delivery across multiple marketing communications channels including print and digital advertising, direct marketing and mail, packaging, sales collateral, in-store marketing and social media.

Variable Consideration

Certain clients may receive volume-based rebates or early payment discounts, which are accounted for as variable consideration. We estimate these amounts based on the expected amount to be earned by our clients and reduce revenue accordingly. We do not expect significant changes to estimates of variable consideration. Given the nature of our products and the history of returns, product returns are not significant.

Contract Balances

The following table provides information about contract assets and liabilities from contracts with clients:

	Contract Liabilities
	Short-Term		Long-Term
Balance at January 1, 2020	$	18.9	$	0.2
Balance at December 31, 2020		15.6		—

Contract liabilities primarily relate to client advances received prior to completion of performance obligations. Reductions in contract liabilities are a result of our completion of performance obligations. Revenue recognized during the year ended December 31, 2020 from amounts included in contract liabilities at the beginning of the period was approximately $16.9 million.

Practical Expedients and Exemptions

As part of the adoption of Topic 606, we have elected practical expedients and exemptions allowable under the guidance.

We account for shipping and handling activities performed after the control of a good has been transferred to the client as a fulfillment cost. We accrue for the costs of shipping and handling activities if revenue is recognized before contractually agreed shipping and handling activities occur.

We apply Topic 606 to a portfolio of contracts (or performance obligations) with similar characteristics as we reasonably expect that the effects on the financial statements of applying this guidance to the portfolio would not differ significantly from applying this guidance to the individual contracts (or performance obligations) within that portfolio.

When the output method for measure of progress is determined appropriate, we recognize revenue in the amount for which we have the right to invoice for revenue that is recognized over time and for which we can demonstrate that the invoiced amount corresponds directly with the value to the client for the performance completed to date.

We generally expense sales commissions and other costs to obtain a contract when incurred, because the amortization period would have been one year or less. These costs are recorded within Selling, general and administrative expenses.

We exclude sales taxes and other similar taxes from the measurement of the transaction price. We do not disclose the value of unsatisfied performance obligations, nor do we disclose the timing of revenue recognition for contracts with an original expected length of one year or less.

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

The current portion of restructuring reserves of $33.3 million at December 31, 2020 was included in Accrued liabilities and other, while the long-term portion of $55.3 million, primarily related to MEPP withdrawal obligations, employee terminations in litigation, environmental reserves and lease termination costs, was included in Other noncurrent liabilities at December 31, 2020. The liabilities for the withdrawal obligations associated with our decision to withdraw from all MEPPs included in Accrued liabilities and other and Other noncurrent liabilities are $17.8 million and $52.4 million, respectively, as of December 31, 2020. See Note 10, Retirement Plans, and Note 9 – Commitment and Contingencies, for further discussion of MEPPs.

We anticipate that payments associated with the employee terminations reflected in the above table will be substantially completed by December 2021, excluding employee terminations in litigation within the Business Services segment.

Payments on all of our MEPP withdrawal obligations are scheduled to be substantially completed by 2034. Changes based on uncertainties in these estimated withdrawal obligations could affect the ultimate charges related to MEPP withdrawals. See Note 10, Retirement Plans, for further discussion on MEPPs.

The restructuring liabilities classified as “other” consisted of reserves for employee terminations in litigation, environmental matters and lease liabilities related to restructured facilities. Any potential recoveries or additional charges could affect amounts reported in our consolidated financial statements.

The restructuring reserve as of December 31, 2019 and 2018, and changes during the year ended December 31, 2019, were as follows:

The current portion of restructuring reserves of $14.8 million at December 31, 2019 was included in Accrued liabilities and other, while the long-term portion of $37.7 million, primarily related to MEPP withdrawal obligations, employee terminations in litigation and lease termination costs, was included in Other noncurrent liabilities at December 31, 2019. The liabilities for the withdrawal obligations associated with our decision to withdraw from all MEPPs included in Accrued liabilities and other and Other noncurrent liabilities are $6.5 million and $34.0 million, respectively, as of December 31, 2019. Note 10, Retirement Plans, for further discussion of MEPPs.

Payments associated with the employee terminations reflected in the above table were substantially completed by December 2020, excluding employee terminations in litigation within the Business Services segment.

Fair Value Disclosures [Abstract]

Fair Value Measurement

Note 7. Fair Value Measurement

Certain assets and liabilities are required to be recorded at fair value on a recurring basis. See Note 13, Derivatives, for further discussion on financial assets and liabilities that are carried at fair value on a recurring basis in the Consolidated Balance Sheets.

In addition to assets and liabilities that are recorded at fair value on a recurring basis, we are required to record certain assets and liabilities at fair value on a nonrecurring basis, generally as a result of acquisitions or the re-measurement of assets resulting in impairment charges.

The fair value as of the measurement date, net book value as of the end of the year and related impairment charge for assets measured at fair value on a nonrecurring basis subsequent to initial recognition during the years ended December 31, 2020, 2019 and 2018 were as follows:

	Year Ended December 31, 2020				As of December 31, 2020

Our accounting and finance management determines the valuation policies and procedures for Level 3 fair value measurements and is responsible for the development and determination of unobservable inputs. In 2020 the Fair Value of long-lived assets which were ultimately impaired was determined to be $0. These assets were therefore written off and have no remaining Net Book Value.

Commitments And Contingencies Disclosure [Abstract]

Commitments and Contingencies

Note 9. Commitments and Contingencies

We are subject to laws and regulations relating to the protection of the environment. We provide for expenses associated with environmental remediation obligations when such amounts are probable and can be reasonably estimated. Such accruals are adjusted as new information develops or circumstances change and are generally not discounted. We have been designated as a potentially responsible party or have received claims in two active federal and state Superfund and other multiparty remediation sites. In addition to these sites, we may also have the obligation to remediate six other previously and currently owned facilities. At the Superfund sites, the Comprehensive Environmental Response, Compensation and Liability Act provides that our liability could be joint and several, meaning that we could be required to pay an amount in excess of our proportionate share of the remediation costs.

Our understanding of the financial strength of other potentially responsible parties at the multiparty sites and of other liable parties at the previously owned facilities has been considered, where appropriate, in the determination of our estimated liability. We believe that our recorded reserves, recorded in Accrued liabilities and other and Other noncurrent liabilities, are adequate to cover our share of the potential costs of remediation at each of the multiparty sites and the previously and currently owned facilities. It is not possible to quantify with certainty the potential impact of actions regarding environmental matters, particularly remediation and other compliance efforts that we may undertake in the future. However, in our opinion, compliance with the present environmental protection laws, before taking into account estimated recoveries from third parties, will not have a material effect on our consolidated results of operations, financial position or cash flows.

In April 2019, we received a subpoena from the SEC related to previous business dealings with the Brazilian Ministry of Education. The SEC and Department of Justice (“DOJ”) are investigating the matter, and we are cooperating as they conduct their investigations. In addition, the Brazil authorities are also investigating the matter.

From time to time, our clients and others file voluntary petitions for reorganization under United States bankruptcy laws. In such cases, certain pre-petition payments received by us from these parties could be considered preference items and subject to return.

We also regularly investigate matters reported to our whistleblower hotline and are currently investigating matters in certain foreign locations. In addition, we may be party to litigation arising in the ordinary course of business.

We believe that the final resolution of these preference items, investigations, and litigation will not have a material effect on our consolidated results of operations, financial position or cash flows.

Leases

We determine if an arrangement is a lease at inception. Operating leases are recorded in Operating lease assets, Short-term operating lease liabilities and Long-term operating lease liabilities on the Consolidated Balance Sheets. Operating lease assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. In determining the present value of lease payments, we use our incremental borrowing rate based on the information available at the lease commencement date. Operating lease assets also include any lease payments made and are reduced by any lease incentives received. Our lease terms may include options to extend or not terminate the lease when we are reasonably certain that we will exercise any such options. Leases with an expected term of 12 months or less are not recorded on the balance sheet. Lease expense is recognized on a straight-line basis over the expected lease term.

Our most significant leases are real estate leases for plants, warehouses, storage facilities, offices and other facilities. For real estate leases, we elected the practical expedient permitted under Topic 842 to combine lease and non-lease components. As a result, non-lease components, such as common area maintenance charges, are accounted for as a single lease element. Our remaining operating leases are primarily comprised of leases of machinery and technology equipment. Finance leases are not material.

Certain of our operating lease agreements include variable payments that are passed-through by the landlord, such as insurance, taxes and common area maintenance, payments based on the usage of the asset and rental payments adjusted periodically for inflation. Pass-through charges, payments due to change in usage of the asset and payments due to changes in inflation are included within variable rent expense.

Our lease agreements do not contain material residual value guarantees, restrictions or covenants.

The components of lease expense for the year ended December 31, 2020 and 2019 were as follows:

	Years Ended December 31,
	2020			2019
Operating lease cost	$	89.3		$	94.4
Variable lease cost		32.7			32.4
Sublease income		(1.7	)		(1.2	)
Total lease cost	$	120.3		$	125.6

Short-term lease cost is not material for the year ended December 31, 2020 and 2019 respectively.

Supplemental cash flow information related to leases for the year ended December 31, 2020 and 2019 was as follows:

Contingencies related to LSC Communication, Inc. and Subsidiaries (“LSC”) and Donnelley Financial Solutions, Inc. (“Donnelley Financial”)

Subsequent to the spinoff of LSC and Donnelley Financial, we may be contingently liable for obligations under various operating leases for office, warehouse and manufacturing locations of LSC and Donnelley Financial. In the event that LSC or Donnelley Financial, or any successor lessee, fail to make lease payments or fail to pay other obligations under these lease agreements, we may be required to satisfy those obligations to the lessor. Our exposure to these potential contingent liabilities is decreasing over time as LSC and Donnelley Financial pay monthly lease obligations and as leases expire. As of December 31, 2020, these potential contingent lease obligations were approximately $49.4 million and $2.8 million for LSC and Donnelley Financial, respectively.

On April 13, 2020, LSC announced that it, along with most of its U.S. subsidiaries, voluntarily filed for business reorganization under Chapter 11 of the U.S. Bankruptcy Code. LSC was subsequently acquired by a third party buyer (the “Buyer”). Although the Buyer assumed the majority of LSC’s existing leases, we will continue to be contingently liable for these leases until their termination or renewal. We believe the future lease obligations not assumed by the Buyer are approximately $3.0 million.

In May and June 2020 we became aware that LSC failed to make required monthly contributions to certain of their multiemployer pension plans (“MEPP”). In accordance with laws and regulations governing multiemployer pension plans, we believe that we and Donnelley Financial, as former members of the control group, are contingently liable on a joint and several liability basis for LSC’s MEPP obligations. We believe that the total undiscounted MEPP obligations for which LSC was responsible is approximately $100.0 million and is payable over an average 13-year period. The amount of our ultimate liability related to LSC's MEPP obligations is contingent upon the outcome of our negotiations with Donnelley Financial concerning how the obligations would be apportioned between us and Donnelley Financial. During the third quarter of 2020, we commenced negotiations with Donnelley Financial related to how the MEPP liabilities would be apportioned between the two parties, and agreed to enter into mediation, and then arbitration if an agreement is not reached though the mediation process. We recorded a contingent liability of approximately $37.1 million representing our current estimate of the aggregate payments we believe we will be required to make with respect to LSC’s MEPP liabilities. This amount however could be adjusted in the future based on the final allocation as a result of the mediation process or arbitration. Payments to settle this liability are scheduled to be completed by 2034.

In addition to the aforementioned contingent obligations, in October 2020, we received a demand notice from a law firm representing more than 30 individuals whose accrued supplemental non-qualified pension benefits were transferred to LSC at the time of the spin. We preliminarily settled this claim, as well as other claims from general unsecured creditors, for $5.5 million in the fourth quarter of 2020. This settlement is subject to final court approval as part of the LSC’s reorganization plan which is expected in the first or second quarter of 2021.

Compensation And Retirement Disclosure [Abstract]

Retirement Plans

Note 10. Retirement Plans

We sponsor various defined benefit retirement income pension plans in the U.S., U.K., Canada and certain other international locations, including both funded and unfunded arrangements. Our primary defined benefit plans are frozen. No new employees will be permitted to enter our frozen plans and participants will earn no additional benefits. Benefits are generally based upon years of service and compensation. These defined benefit retirement income plans are funded in conformity with the applicable government regulations. We fund at least the minimum amount required for all funded plans using actuarial cost methods and assumptions acceptable under government regulations.

We made contributions of $9.2 million to our pension plans during the year ended December 31, 2020. We expect to make cash contributions of approximately $5.5 million to our pension plans in 2021.

In addition to the pension plans, we sponsor a 401(k) savings plan, which is a defined contribution retirement income plan.

Certain former employees are entitled to healthcare and life insurance benefits provided they have met certain eligibility requirements. Generally, these former employees became eligible for these retiree healthcare benefits if they met all of the following requirements at the time of termination: (a) attained at least 55 or more points (full years of service and age combined), (b) were at least fifty years of age, (c) had at least two years of continuous, regular, full-time, benefits-eligible service and (d) completed at least two or more years of continuous service with a participating employer, which ended on their termination date. Different requirements need to be met in order to receive subsidized medical and life insurance coverage. This plan was frozen in 2016. Certain of the plan expenses are paid through a tax-exempt trust. Most of the assets of the trust are invested in trust-owned life insurance policies covering certain current and former employees of ours. The underlying assets of the policies are invested primarily in marketable equity, corporate fixed income and government securities.

We operate a prescription drug program for certain Medicare-eligible retirees under a group-based Company-sponsored Medicare Part D program, or Employer Group Waiver Program (“EGWP”). The EGWP subsidies provided to or for the benefit of this program are used to reduce our net retiree medical and prescription drug costs on a group by group basis until such net costs of ours for such group are eliminated, and any EGWP subsidies received in excess of the amount necessary to offset such net costs are used to reduce the included group of retirees’ premiums.

We also maintain several pension and OPEB plans in certain international locations. The expected returns on plan assets and discount rates for these plans are determined based on each plan’s investment approach, local interest rates and plan participant profiles.

The pension and OPEB plan obligations are calculated using generally accepted actuarial methods and are measured as of December 31. Actuarial gains and losses for frozen plans are amortized using the corridor method over the average remaining expected life of active plan participants.

The components of the net periodic benefit expense, (income) and total (income) were as follows:

The accumulated benefit obligation for all defined benefit pension plans was $1,126.2 million and $1,049.9 million at December 31, 2020 and 2019, respectively.

Actuarial gains and losses result from changes in actuarial assumptions, such as changes in the discount rate and revised mortality rates. Actuarial losses in 2020 and 2019 related to plan benefit obligations were primarily the result of changes in discount rates.

Amounts recognized in the Consolidated Balance Sheets as of December 31, 2020 and 2019 were as follows:

Actuarial gains and losses in excess of 10.0% of the greater of the projected benefit obligation or the market-related value of plan assets were recognized as a component of net periodic benefit costs over the average remaining service period of a plan’s active employees. As a result of the plan freezes, the actuarial gains and losses are recognized as a component of net periodic benefit costs over the average remaining life 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. For plans that are frozen or primarily inactive, unrecognized prior service costs or credits are recognized over the average life expectancy of the plan’s participants.

The weighted average assumptions used to determine the benefit obligation at the measurement date were as follows:

	Pension Benefits						OPEB
	2020			2019			2020			2019
Discount rate		2.4	%		3.0	%		2.2	%		3.0	%
Health care cost trend:
Current
Pre-Age 65		—			—			6.2	%		6.2	%
Post-Age 65		—			—			6.2	%		6.2	%
Ultimate		—			—			4.5	%		4.5	%
Interest crediting rate for cash balance plans		2.4	%		3.4	%		—			—

The following table provides a summary of under-funded or unfunded pension benefit plans with projected benefit obligations in excess of plan assets as of December 31, 2020 and 2019:

	Pension Benefits
	2020		2019
Projected benefit obligation	$	872.0	$	819.7
Fair value of plan assets		780.0		705.5

The following table provides a summary of pension plans with accumulated benefit obligations in excess of plan assets as of December 31, 2020 and 2019:

	Pension Benefits
	2020		2019
Accumulated benefit obligation	$	860.1	$	811.3
Fair value of plan assets		780.0		705.5

We determine our assumption for the discount rate to be used for purposes of computing interest costs based on an index of high-quality corporate bond yields and matched-funding yield curve analysis as of the measurement date.

The Medicare Prescription Drug, Improvement and Modernization Act of 2003 included a prescription drug benefit under Medicare Part D, as well as a federal subsidy that began in 2006, to sponsors of retiree health care plans that provide a benefit that is at least actuarially equivalent, as defined in the Act, to Medicare Part D. Two of our retiree health care plans were at least actuarially equivalent to Medicare Part D and were eligible for the federal subsidy. During the years ended December 31, 2020 and 2019, Medicare Part D subsidies received by us were negligible.

During the year ended December 31, 2020, we received approximately $7.9 million in EGWP subsidies.

Benefit payments are expected to be paid as follows:

	Pension Benefits		OPEB-Gross		Estimated Subsidy Reimbursements
2021	$	47.2	$	24.1	$	1.5
2022		48.0		24.0		1.5
2023		49.3		23.8		1.5
2024		51.0		23.3		1.5
2025		51.9		22.8		1.5
2026-2030		271.7		105.1		6.8

Plan Assets

Our U.S. pension plans are frozen and we utilize a risk management approach for our U.S. pension plan assets. The overall investment objective of this approach is to further reduce the risk of significant decreases in the plan’s funded status by allocating a larger portion of the plan’s assets to investments expected to hedge the impact of interest rate risks on the plan’s obligation. Over time, the target asset allocation percentage for the pension plan is expected to decrease for equity and other “return seeking” investments and increase for fixed income and other “hedging” investments. The assumed long-term rate of return for plan assets, which is determined annually, is likely to decrease as the asset allocation shifts over time. The expected long-term rate of return for plan assets is based upon many factors including asset allocations, historical asset returns, current and expected future market conditions, risk and active management premiums. The target asset allocation percentage as of December 31, 2020, for the primary U.S. pension plan was approximately 50% for return seeking investments and approximately 50% for hedging investments.

We segregated our plan assets by the following major categories and levels for determining their fair value as of December 31, 2020 and 2019. All plan assets that are valued using the net asset value per share (“NAV”) practical expedient have not been included within the fair value hierarchy but are separately disclosed.

Cash and cash equivalents— Carrying value approximates fair value. As such, these assets were classified as Level 1. We also invest in certain short-term investments which are valued at their unit value per share available to eligible participants at the measurement date. As such, these assets were classified as Level 2.

Equity— The values of individual equity securities were based on quoted prices in active markets. As such, these assets are classified as Level 1. Additionally, this category includes underlying securities in trust owned life insurance policies which are invested in certain equity securities. These investments are not quoted on active markets; therefore, they are classified as Level 2. Additionally, we invest in certain equity funds that are valued at calculated NAV.

Fixed income— The values of certain fixed income securities were based on quoted prices in active markets. As such, these assets are classified as Level 1. The remaining fixed income securities are typically priced based on a valuation model rather than a last trade basis and are not exchange-traded. These valuation models involve utilizing dealer quotes, analyzing market information, estimating prepayment speeds and evaluating underlying collateral to equate an NAV. Accordingly, we classified these fixed income securities as Level 2. We also invest in certain fixed income funds and securities in trust owned life insurance policies which are valued at NAV and included as Level 2.

Real estate—The fair market value of real estate investment trusts is based on NAV.

For Level 2 and Level 3 plan assets, as applicable, we review significant investments on a quarterly basis including investigation of unusual fluctuations in price or returns and obtaining an understanding of the pricing methodology to assess the reliability of third-party pricing estimates.

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 we believe the valuation methodologies used are appropriate, the use of different methodologies or assumptions in calculating fair value could result in different amounts. We invest in various assets in which valuation is determined by NAV. We believe that the NAV is representative of fair value at the reporting date, as there are no significant restrictions on redemption of these investments or other reasons to indicate that the investment would be redeemed at an amount different than the NAV.

The fair values of our 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		Total		Level 1		Level 2

The fair values of our OPEB 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		Total		Level 1		Level 2

Employee 401(k) Savings Plan — For the benefit of most of our U.S. employees, we maintain a defined contribution retirement savings plan that is intended to be qualified under Section 401(a) of the Internal Revenue Code. Under this plan, employees may contribute a percentage of eligible compensation on both a before-tax and after-tax basis. We may provide a 401(k) discretionary match to participants, but did not during the years ended December 31, 2020, 2019 and 2018.

MEPPs — MEPPs receive contributions from two or more unrelated employers pursuant to one or more collective bargaining agreements and the assets contributed by one employer may be used to fund the benefits of all employees covered within the plan. The risk and level of uncertainty related to participating in these MEPPs differs significantly from the risk associated with the Company-sponsored defined benefit plans. For example, investment decisions are made by parties unrelated to us and the financial stability of other employers participating in a plan may affect our obligations under the plan.

During each of the years ended December 31, 2020, 2019 and 2018, we recorded $40.0 million, $2.9 million and $2.9 million for MEPP withdrawal obligations, respectively. These charges were recorded as net restructuring, impairment and other charges and represent our best estimate of the expected settlement of these withdrawal liabilities. Total contributions to these plans for the years ended December 31, 2020 and 2019 were $10.3 million and $6.5 million, respectively. See Note 5, Restructuring, Impairment and Other Charges, for further discussion on MEPP.

Total	$	10.0		$	54.9	$	31.5

The following is a reconciliation of income tax expense at the U.S. federal statutory tax rate for the years ended December 31, 2020, 2019 and 2018:

	2020			2019			2018
Income taxes at the U.S. federal statutory tax rate	$	(3.3	)	$	10.6		$	0.3

Total	$	10.0		$	54.9		$	31.5

Included in 2020, 2019 and 2018 is the tax impact of limitations on our interest expense deduction as a result of the Tax Act. Non-deductible interest expense will be carried forward as a deferred tax asset; however, it is more likely than not that the benefit of the deferred tax asset will not be fully realized and a full valuation allowance was recorded.

Included in 2020 is the impact from the surrender of corporate owned life insurance policies as well as tax benefits from additional interest expense deductions as result of the Cares Act and additional tax guidance issued in 2020.

Included in 2018 is the final income tax expense adjustment associated with the enactment of the Tax Act, which included the one-time transition tax on foreign earnings, as well as $1.5 million to net deferred tax assets for the reduced corporate income tax rate. Additionally, the 2018 rate includes the inability to recognize a tax benefit on certain losses.

Deferred income taxes

The significant deferred tax assets and liabilities at December 31, 2020 and 2019 were as follows:

	2020			2019
Deferred tax assets:
Pension and OPEB plan liabilities	$	29.1		$	38.9
Net operating losses and other tax carryforwards		195.6			205.6
Interest limitation carryforward		21.4			49.6
Accrued liabilities		48.6			53.9

Total deferred tax assets		390.2			436.7
Valuation allowances		(195.7	)		(237.5	)
Net deferred tax assets	$	194.5		$	199.2

Inventories		(8.6	)		(10.0	)
Operating lease assets		(58.1	)		(47.4	)
Other		(5.7	)		(16.4	)
Total deferred tax liabilities		(130.5	)		(153.5	)

Total net deferred tax assets	$	64.0		$	45.7

The change in net deferred tax assets includes the use of previously disallowed interest and capital losses and their associated valuation allowances as a result of the net gain on sale from discontinued operations.

Transactions affecting the valuation allowances on deferred tax assets during the years ended December 31, 2020, 2019 and 2018 were as follows:

	2020			2019			2018
Balance, beginning of year	$	237.5		$	255.9		$	238.3
Current year expense-net		(44.8	)		34.5			29.1
Write-offs		—			(50.1	)		(0.2	)
Foreign exchange and other		3.0			(2.8	)		(11.3	)
Balance, end of year		195.7			237.5		$	255.9

As of December 31, 2020, we had domestic and foreign net operating loss and other tax credit carryforwards of approximately $126.8 million and $68.8 million ($141.2 million and $64.4 million, respectively, at December 31, 2019), of which $113.5 million expires between 2021 and 2030. Limitations on the utilization of these deferred tax assets may apply therefore we have provided valuation allowances of $174.4 million on these deferred tax assets as of December 31, 2020 ($187.9 million at December 31, 2019).

We are not permanently reinvested on certain foreign earnings yet remain permanently reinvested on all other foreign earnings and other outside basis differences. We have recognized deferred tax liabilities of $4.5 million, $6.7 million and $6.5 million as of December 31, 2020, 2019 and 2018, respectively, related to local taxes on certain foreign earnings which are not considered to be permanently reinvested.

Cash payments for income taxes were $68.7 million, $73.1 million and $37.2 million during the years ended December 31, 2020, 2019 and 2018, respectively. Cash refunds for income taxes were $7.2 million, $12.1 million and $52.5 million during the years ended December 31, 2020, 2019 and 2018, respectively.

Our income taxes payable for federal and state purposes has been reduced by the tax benefits associated with the exercise and vesting of stock based compensation awards.

See Note 15, Other Comprehensive Loss, for details of the income tax expense or benefit allocated to each component of other comprehensive loss.

Uncertain tax positions

Changes in unrecognized tax benefits at December 31, 2020, 2019 and 2018 were as follows:

	2020			2019			2018
Balance at beginning of year	$	23.1		$	25.0		$	30.9
Additions for tax positions of the current year		—			0.1			0.2
Additions for tax positions of prior years		4.1			—			—
Reductions for tax positions of prior years		(2.1	)		—			(2.8	)
Settlements during the year		(2.9	)		(0.4	)		(0.1	)
Lapses of applicable statutes of limitations		(1.5	)		(1.6	)		(3.2	)
Balance at end of year	$	20.7		$	23.1		$	25.0

As of December 31, 2020, 2019 and 2018, we had $20.7 million, $23.1 million and $25.0 million, respectively, of unrecognized tax benefits. Unrecognized tax benefits of $13.3 million as of December 31, 2020, if recognized, would decrease income taxes.

As of December 31, 2020, it is reasonably possible that the total amount of unrecognized tax benefits will decrease within twelve months by as much as $10.8 million due to the resolution of audits or expirations of statutes of limitations related to U.S. federal, state and international tax positions.

We classify interest expense and any related penalties related to income tax uncertainties as a component of income tax expense. The total interest (benefit) expense related to tax uncertainties recognized in the Consolidated Statements of Operations were insignificant for the years ended December 31, 2020, 2019 and 2018, respectively. There were no benefits from the reversal of accrued penalties for the years ended December 31, 2020, 2019 and 2018. Accrued interest of $3.7 million and $3.6 million related to income tax uncertainties are reported in Other noncurrent liabilities in the Consolidated Balance Sheets at December 31, 2020 and 2019, respectively. There were no accrued penalties related to income tax uncertainties for the years ended December 31, 2020 and 2019.

We have tax years from 2010 and thereafter that remain open and subject to examination by the IRS, certain state taxing authorities or certain foreign tax jurisdictions.

(a)

As of December 31, 2020 and 2019, the interest rate on the Term Loan due January 15, 2024 was 5.15% and 6.80%, respectively.

The fair values of the senior notes and debentures, which were determined using the market approach based upon quoted prices or interest rates available to us for debt obligations with similar terms and maturities, were determined to be Level 2 under the fair value hierarchy. The fair value of our total debt was greater than its book value by approximately $142.9 million and $29.3 million at December 31, 2020 and 2019, respectively.

During the year ended December 31, 2020, we executed various transactions that reduced our near-term maturities and extended our debt maturity profile. During this period, we repurchased on the open market $98.5 million aggregate principal of debt maturing in 2020, 2021, and 2022, including $1.3 million of the 7.625% notes due 2020 (the “2020 Notes”), $67.6 million aggregate principal of 7.875% notes due 2021 (the “2021 Notes”), $1.3 million aggregate principal of the 8.875% debentures due 2021 (the “2021 Debentures”), and $28.3 million aggregate principal of the 7.000% notes due in 2022 (the “2022 Notes”) using available cash. These repurchases included a cumulative premium of $0.9 million.

On December 4, 2020, we redeemed the remaining $83.3 million aggregate principal outstanding of the 2021 Notes using a combination of available cash and a borrowing under our ABL Credit Facility. The redemption price included a premium of $1.7 million.

On June 18, 2020, we completed a public exchange transaction in which we exchanged $246.2 million aggregate principal amount of the Company’s debt held by various investors maturing between 2021 and 2024 (the “Old Debt”) for $244.9 million aggregate principal amount of newly issued unsecured 8.25% notes due 2027 (the “New 2027 Notes”). The Old Debt that was exchanged consisted of $16.4 million of the 2021 Notes; $3.3 million of the 2021 Debentures; $25.8 million of the 2022 Notes; $161.6 million of the 6.500% notes due 2023 (the “2023 Notes”); and $39.1 million of the 6.000% of notes due 2024 (the “2024 Notes”). Other than the interest rate, the terms of the New 2027 Notes are substantially similar to the terms of the Old Debt. We treated the transaction as a debt modification, which resulted in a premium on the New 2027 Notes of approximately $1.0 million.

In March 2020, we entered into privately negotiated agreements with the largest holder of our outstanding notes (the “Holder”) to extend a significant portion of the Company’s 2023 and 2024 maturities. The agreements included the exchange of $277.0 million aggregate principal amount of notes owned by the Holder, consisting of $54.0 million of the 2023 Notes, $177.4 million of the 2024 Notes, and $45.6 million of the 6.625% debentures due 2029 (the “2029 Debentures”) for $297.0 million aggregate principal amount of newly issued unsecured 8.50% notes due 2029 (the “New 2029 Notes”). Other than the interest rate, the terms of the New 2029 Notes are substantially similar to the terms of the 2029 Debentures. We treated the transaction as a debt modification, which resulted in a discount on the New 2029 Notes of approximately $20 million, inclusive of approximately $0.3 million of fees paid to the Holder. The exchange was executed in a series of transactions that were completed on April 8, 2020. The agreements also included the repurchase of $6.6 million of the 2022 Notes and $20.0 million of the 2024 Notes. These repurchases were completed in March and were funded with a draw from our ABL Credit Facility. We recorded a gain of $0.2 million on these repurchases.

In May 2020, we entered into an additional agreement with the Holder in which the Holder agreed to exchange approximately $9.0 million aggregate principal amount of the 2029 Debentures and $14.5 million aggregate principal amount of 8.820% Debentures due 2031 for approximately $21.2 million aggregate principal amount of New 2029 Notes. This transaction was completed on June 19, 2020. We treated the transaction as a debt modification, which resulted in a premium on the New 2029 Notes of approximately $2.1 million, inclusive of $0.2 million of fees paid to the Holder.

During the year ended December 31, 2019, we repurchased on the open market $23.4 million and $20.7 million in aggregate principal amount of the 2021 Notes and 2021 Debentures, respectively. We recorded a loss on debt extinguishment of $0.8 million in 2019 on these repurchases.

On October 15, 2018, we entered into a $550.0 million senior secured term loan B (the “Term Loan”) pursuant to a credit agreement (the “Term Loan Credit Agreement”). Proceeds from the Term Loan, net of a $5.5 million discount, were used to repurchase certain senior notes, pay transaction fees and repay a portion of borrowings under the ABL Credit Facility. The Term Loan is scheduled to mature on January 15, 2024, at which time the remaining outstanding balance under the Term Loan will be due and payable. Principal payments of $1.4 million are due quarterly. The Term Loan bears interest based on the London Interbank Offered Rate (LIBOR) plus a margin of 5% or a base rate plus a margin of 4%.

On October 15, 2018, we repurchased $172.6 million and $257.4 million in aggregate principal amount of the 2020 Notes and the 2021 Notes, respectively, pursuant to a tender offer. We recorded a loss on debt extinguishment of $32.3 million in the fourth quarter of 2018 on the repurchase of the bonds, representing tender premiums paid of $29.0 million, write-off of unamortized debt issuance costs of $1.5 million and fees and expenses of $1.8 million.

We entered into an $800.0 million senior secured asset-based revolving credit facility (the “ABL Credit Facility”) on September 29, 2017, pursuant to a credit agreement (the “ABL Credit Agreement”), which replaced our prior $800.0 million senior secured revolving credit facility dated September 30, 2016.

On October 15, 2018, we amended the ABL Credit Agreement to, among other things, permit (i) the incurrence of the debt pursuant to the Term Loan Credit Agreement and (ii) the incurrence of a lien on the ABL Priority Collateral (described below) to secure our obligations under the Term Loan Credit Agreement and related guarantees on a second-priority basis. The ABL Credit Facility is scheduled to mature on September 29, 2022, at which time all outstanding amounts under the ABL Credit Facility will be due and payable.

The amount available to be borrowed under the ABL Credit Facility is equal to the lesser of (a) $800.0 million and (b) a borrowing base formula based on the amount of accounts receivable, inventory, machinery, equipment and, if we were to so elect in the future subject to the satisfaction of certain conditions, fee-owned real estate of ours and our material domestic subsidiaries, subject to certain eligibility criteria and advance rates (collectively, the “Borrowing Base”). The aggregate amount of real estate, machinery and equipment that can be included in the Borrowing Base formula cannot exceed $200.0 million.

Borrowings under the ABL Credit Facility bear interest at a rate dependent on the average quarterly availability and is calculated according to a base rate (except in certain circumstances, based on the prime rate) or a Eurocurrency rate (except in certain circumstances, based on LIBOR) plus an applicable margin. The applicable margin for base rate loans ranges from 0.25% to 0.50% and the applicable margin for Eurocurrency loans ranges from 1.25% to 1.50%. In addition, a fee is payable quarterly on the unused portion of the total commitments. This fee accrues at a rate of either 0.25% or 0.375% depending upon the average usage of the facility. Borrowings under the ABL Credit Facility may be used for working capital and general corporate purposes.

Based on our Borrowing Base as of December 31, 2020 and existing borrowings, we had approximately $575.9 million of borrowing capacity available under the ABL Credit Facility. The weighted average interest rate on borrowings under our ABL Credit Facility was 1.7%, 3.7%, 3.5% for the years ended December 31, 2020, 2019 and 2018, respectively.

Our obligations under the ABL Credit Facility are guaranteed by our material domestic subsidiaries (the “Guarantors”) and are secured by a security interest in substantially all assets of ours and the Guarantors, including, only to the extent included in the Borrowing Base, real property, in each case subject to certain exceptions and exclusions. The assets of ours and the Guarantors consisting of accounts receivable, inventory, deposit accounts, securities accounts, machinery and equipment and, to the extent related to the foregoing, general intangibles, documents and instruments, as well as 65% of the equity interests of our first-tier foreign subsidiaries (collectively, the “ABL Priority Collateral”), secure our obligations and the obligations of the Guarantors under the ABL Credit Facility and the related guarantees on a first-priority basis, and all other collateral other than the ABL Priority Collateral secures our obligations and the obligations of the Guarantors under the ABL Credit Facility on a second-priority basis, in each case, subject to permitted liens.

Our obligations under the Term Loan Credit Agreement are guaranteed by the Guarantors and are secured by a security interest in substantially all assets of ours and the Guarantors, including certain material real property, subject to certain exceptions and exclusions. The ABL Priority Collateral secures our obligations and the obligations of the Guarantors under the Term Loan Credit Agreement and related guarantees on a second-priority basis, and all other collateral other than the ABL Priority Collateral secures our obligations and the obligations of the Guarantors under the Term Loan Credit Agreement and related guarantees on a first-priority basis, in each case, subject to permitted liens.

Our debt agreements contain customary affirmative and negative covenants including negative covenants restricting, among other things, our ability to incur debt, make investments, make certain restricted payments (including payments on certain other debt and external dividends), incur liens securing other debt, consummate certain fundamental transactions, enter into transactions with affiliates and consummate asset sales. The ABL Credit Agreement contains a covenant which requires us to maintain a minimum fixed charge coverage ratio of 1.0 to 1.0 if availability under the ABL Credit Facility declines below certain levels. The Term Loan Credit Agreement requires that the net cash proceeds of significant asset sales be used to prepay the Term Loan to the extent that the net cash proceeds are not used for reinvestment in assets useful to our business, certain acquisitions and investments, repayment of certain borrowings under our ABL Credit Facility or the funding of debt repayments, redemptions or tenders of certain existing notes maturing prior to the maturity of the Term Loan, in each case, subject to certain restrictions and limitations set forth in the Term Loan Credit Agreement.

As of December 31, 2020, we had no outstanding borrowings and $56.1 million of letters of credit issued under the ABL Credit Facility. We also had $166.5 million in other uncommitted credit facilities, primarily outside the U.S. (the “Other Facilities”), of which we had $91.5 million in outstanding letters of credit, bank guarantees and bank acceptance drafts.

At December 31, 2020, the future maturities of debt were as follows:

	Amount
2021		61.1
2022		84.8
2023		80.5
2024		584.2
2025		—
2026 and thereafter		721.3
Total ^(a)	$	1,531.9

(a)	Excludes unamortized debt issuance costs of $9.6 million and $19.2 million of bond discount which do not represent contractual commitments with a fixed amount or maturity date.

Derivative Instruments And Hedging Activities Disclosure [Abstract]

Derivatives

Note 13. Derivatives

All derivatives are recorded as other current or noncurrent assets or other current or noncurrent liabilities in the Consolidated Balance Sheets at their respective fair values. Unrealized gains and losses related to derivatives are recorded in the Consolidated Statements of Operations, or in other comprehensive income (loss), net of applicable income taxes, depending on the purpose for which the derivative is held. At the inception of a hedge transaction, we formally document the hedge relationship and the risk management objective for undertaking the hedge. In addition, we assess both at inception of the hedge and on an ongoing basis, whether the derivative in the hedging transaction has been highly effective in offsetting changes in fair value or cash flows of the hedged item and whether the derivative is expected to continue to be highly effective. The impact of any ineffectiveness is also recognized in the Consolidated Statements of Operations.

We are exposed to the impact of foreign currency fluctuations based on our global operations. Foreign currency fluctuations affect the U.S. dollar value of revenues earned and expenses incurred in foreign currencies. We are also exposed to currency risk to the extent we own assets or incur liabilities, or enter into other transactions that are not in the functional currency of the subsidiary in which we operate. We employ different practices to manage these risks, including where appropriate the use of derivative instruments, such as foreign currency forward contracts. To the extent the gains and losses associated with the fair values of foreign currency derivatives are recognized in the Consolidated Statements of Operations, they are generally offset by gains and losses on underlying payables, receivables and net investments in foreign subsidiaries. We do not use derivative financial instruments for trading or speculative purposes. The aggregate notional value of the forward contracts at December 31, 2020 and 2019 was $220.7 million and $179.9 million, respectively. The fair values of foreign currency contracts were determined to be Level 2 under the fair value hierarchy and are valued using market exchange rates.

In the fourth quarter of 2019 and the first quarter of 2020, we entered into interest rate swap agreements to manage interest rate risk exposure, effectively changing the interest rate on $400.0 million of our floating-rate Term Loan based on LIBOR to a fixed-rate. The interest rate swaps, with a notional value of $400.0 million, were designated as cash flow hedges against the variability of cash flows associated with our Term Loan scheduled to mature on January 15, 2024, which are attributable to changes in the benchmark interest rate.

The fair values of interest rate swaps were determined to be Level 2 under the fair value hierarchy and were developed using the market standard methodology of netting the discounted future variable cash payments and the discounted expected fixed cash receipts. Credit valuation adjustments, which consider the impact of any credit enhancements to the contracts, are incorporated in the fair values to account for potential nonperformance risk. We evaluate the credit value adjustments of the interest rate swap agreements, which take into account the possibility of counterparty and our own default, on at least a quarterly basis.

Our foreign currency contracts and interest rate swaps are subject to master netting agreements that allow us to settle positive and negative positions with the respective counterparties. Under these master netting agreements, net settlement generally permits us or the counterparty to determine the net amount payable for contracts due on the same date and in the same currency for similar types of derivative transactions. The master netting agreements generally also provide for net settlement of all outstanding contracts with a counterparty in the case of an event of default or a termination event.

We manage credit risk for our derivative positions on a counterparty-by-counterparty basis, considering the net portfolio exposure with each counterparty, consistent with our risk management strategy for such transactions. Our agreements with each of our counterparties contain a provision where we could be declared in default on our derivative obligations if we either default or, in certain cases, are capable of being declared in default of any of our indebtedness greater than specified thresholds. These agreements also contain a provision where we could be declared in default subsequent to a merger or restructuring type event if the creditworthiness of the resulting entity is materially weakened.

As of December 31, 2020 and 2019, the fair values of our derivative financial instruments and their classifications on the Consolidated Balance Sheets were as follows:

Earnings Per Share [Abstract]

Earnings per Share

Note 14. Earnings per Share

Basic earnings per share is calculated by dividing net earnings attributable to RRD common stockholders by the weighted average number of common shares outstanding for the period. In computing diluted earnings per share, basic earnings per share is adjusted for the assumed issuance of all potentially dilutive share-based awards, including stock options, restricted stock units and performance share units. Performance share units are excluded if the performance targets upon which the issuance of the shares is contingent have not been achieved and the respective performance period has not been completed as of the end of the current period. Additionally, stock options are considered anti-dilutive when the exercise price exceeds the average market value of our stock price during the applicable period. In periods when we are in a net loss from continuing operations, share-based awards are excluded from the calculation of earnings per share as their inclusion would have an antidilutive effect.

During the years ended December 31, 2020, 2019 and 2018, no shares of common stock were purchased by us, however, shares were withheld for tax liabilities upon the vesting of equity awards.

The reconciliation of the numerator and denominator of the basic and diluted earnings per share calculation and the anti-dilutive share-based awards for the years ended December 31, 2020, 2019 and 2018 were as follows:

Share Based Compensation [Abstract]

Stock and Incentive Programs for Employees and Directors

Note 16. Stock and Incentive Programs for Employees and Directors

We recognize compensation expense based on estimated grant date fair values for all share-based awards issued to employees and directors, including stock options, restricted stock units and performance share units. We estimate the fair value of share-based awards based on assumptions as of the grant date. We recognize compensation expenses for those awards expected to vest, on a straight-line basis over the requisite service period of the award, which is generally the vesting term of three years for restricted stock awards and stock options and the performance period for performance share units. For those awards in which there is no requisite service period, we immediately recognize the compensation expense. We recognize forfeitures as they occur as a reduction of compensation expense.

Share-Based Compensation Expense

The total share-based compensation expense was $8.1 million, $10.9 million and $8.6 million for the years ended December 31, 2020, 2019 and 2018, respectively. The resulting income tax benefit was $2.1 million, $2.8 million and $2.2 million for the years ended December 31, 2020, 2019 and 2018, respectively. As of December 31, 2020, $4.7 million of unrecognized compensation expense related to share-based compensation plans is expected to be recognized over a weighted-average period of 1.4 years.

Share-Based Compensation Plans

We have one share-based compensation plan under which we may grant future awards, as described below, and one terminated or expired share-based compensation plan under which awards remain outstanding.

The 2017 Performance Incentive Plan (“2017 PIP”) was approved by stockholders to provide incentives to our key employees. Awards under the 2017 PIP are generally not restricted to any specific form or structure and could include, without limitation, stock options, stock units, restricted stock awards, cash or stock bonuses and stock appreciation rights. There were 7.3 million shares of common stock reserved and authorized for issuance under the 2017 PIP. At December 31, 2020, there were 1.7 million shares of common stock authorized and available for grant under the 2017 PIP.

General Terms of Awards

Under various incentive plans, we have granted certain employees non-qualified stock options, restricted stock units, performance share units and cash-settled stock units (“phantom stock units”). The Human Resources Committee of the Board of Directors has discretion to establish the terms and conditions for grants, including the number of shares, vesting and required service or other performance criteria. The maximum term of any award under the 2017 PIP and previous plans is ten years.

The exercise price of a stock option is equal to the closing price of our common stock on the option grant date and generally vest over four years. Options generally expire ten years from the date of grant or five years after the date of retirement, whichever is earlier.

The rights granted to the recipient of restricted stock unit awards generally accrue ratably over the restriction or vesting period, which is generally three years. We have also granted restricted stock unit awards which cliff vest three years from the grant date. Restricted stock unit awards are subject to forfeiture upon termination of employment prior to vesting, subject in some cases to early vesting upon specified events, including death or permanent disability of the grantee, termination of the grantee’s employment under certain circumstances or a change in control of the Company. We record compensation expense of restricted stock unit awards based on the fair value of the awards at the date of grant ratably over the period during which the restrictions lapse. Dividends are not paid on restricted stock units.

Awards that may be paid in cash are classified as liability awards due to their expected settlement in cash, and are included in Accrued liabilities and other in the Consolidated Balance Sheets. Compensation expense for these awards is measured based upon the fair value of the awards at the end of each reporting period. Awards payable only in shares are classified as equity awards due to their expected settlement in common stock. Compensation expense for these awards is measured based upon the fair value of the awards at the date of grant. Dividend equivalents are accrued for shares awarded to the Board of Directors and paid in the form of cash.

We have granted performance share unit awards to certain executive officers and senior management. Distributions under these awards are payable at the end of their respective performance periods in common stock or cash, at our discretion. The number of share units that vest can range from zero to 150% for the 2020, 2019 and 2018 awards, depending on achievement of a targeted performance metric for a performance period of three years inclusive of the year in which the award was granted. These awards are subject to forfeiture upon termination under certain circumstances prior to vesting. We expense the cost of the performance share unit awards based on the fair value of the awards at the date of grant and the estimated achievement of the performance metric, ratably over the performance period of three years.

In addition, we have granted phantom stock units to certain members of senior management. These awards vest and are payable in three equal installments over a period of three years after the grant date. Phantom stock units are not shares of our common stock and therefore the recipients of these awards do not receive ownership interest in the Company or stockholder voting rights. These awards are subject to forfeiture upon termination of employment prior to vesting, subject in some cases to early vesting upon specified events, including death or permanent disability of the grantee, termination of the grantee’s employment under certain circumstances or a change in control of the Company. All phantom stock unit awards are classified as liability awards due to their expected settlement in cash, and are included in Accrued liabilities and other in the Consolidated Balance Sheets. Compensation expense for these awards is measured based upon the fair value of the awards at the end of each reporting period. Dividends are not paid on phantom stock units.

Stock Options

There were no options granted during the years ended December 31, 2020, 2019 and 2018.

Stockholder Rights Plan

Equity [Abstract]

Stockholder Rights Plan

Note 17. Stockholder Rights Plan

On August 28, 2019, our Board of Directors approved a Stockholder Rights Agreement (the “Rights Agreement”). Our Board of Directors approved an amendment of the Rights Agreement on August 17, 2020 to extend the agreement for an additional year. Under the terms of the Rights Agreement, each share of our common stock is accompanied by one right; each right entitles the stockholder to purchase from the Company one one-thousandth of a newly issued share of Series A Junior Participating Preferred Stock at an exercise price of $12 per share, subject to adjustment.

Subject to certain exceptions, the rights become exercisable 10 business days following a public announcement that a person (the “Acquiring Person”) has acquired beneficial ownership of 10% (or 20% in certain circumstances ) or more of the outstanding shares of common stock of the Company (the “Stock Acquisition Date”). The rights will expire on August 28, 2021, unless redeemed, exchanged or terminated earlier by the Company. The Rights Agreement can be amended by our Board of Directors allowing for an extension of the expiration date. At any time until 10 business days following the Stock Acquisition Date, the Company may redeem the rights for $0.001 per right.

In the event a person becomes an Acquiring Person, each holder of a right, other than the Acquiring Person, will have the right to receive common stock (or, in certain circumstances, cash, property or other securities of the Company) having a value equal to two times the exercise price of the right.

In the event that we are acquired in a merger or other business combination as defined in the Rights Agreement, or 50% or more of our assets or earnings power is sold, each right entitles the holders to purchase common stock of the acquiring company having a value equal to two times the exercise price of the right.

At any time after a person becomes an Acquiring Person and prior to the acquisition by any person or group of 50% or more of the outstanding common stock, the Board of Directors may exchange the rights (other than rights owned by such person or group which have become void), in whole or in part, at an exchange ratio of one share of common stock, or one one-thousandth of a share of Series A Preferred Stock (or of a share of a class or series of the Company’s preferred stock having equivalent rights, preferences and privileges), per right, subject to adjustment.

Accounting Changes And Error Corrections [Abstract]

New Accounting Pronouncements

Note 19. New Accounting Pronouncements

Recently Adopted Accounting Pronouncements

In August 2018, the FASB issued ASU No. 2018-14 “Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans” (“ASU 2018-14”), which removes certain disclosures that are no longer cost beneficial and also includes additional disclosures to improve the overall usefulness of the disclosure requirements to financial statement users. ASU 2018-14 will be effective for public entities for fiscal years ending after December 15, 2020; early adoption is permitted. We adopted ASU 2018-14 on December 31, 2020 and have reflected the required disclosure modifications in Note 10, Retirement Plans.

In June 2016, the FASB issued ASU No. 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. Under the new guidance, entities are required to measure expected credit losses for financial instruments, including trade receivables, based on historical experience, current conditions and reasonable forecasts. ASU 2016-13 is effective for public entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. We established a cross-functional implementation team to analyze the effect of Topic 326. The analysis included identifying pools of receivables, developing and assessing estimation methodologies, policy elections, and evaluating our business processes and internal controls to meet the accounting, reporting and disclosure requirements. On January 1, 2020, we adopted and applied Topic 326 using the modified retrospective method. The cumulative adjustment to retained earnings was $0.3 million.

Accounting Pronouncements Issued and Not Yet Adopted

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform, which provides companies with optional guidance, including expedients and exceptions for applying generally accepted accounting principles to contracts and other transactions affected by reference rate reform, such as LIBOR. This new standard was effective upon issuance and generally can be applied to applicable contract modifications through December 31, 2022. None of our debt contracts have been modified in 2020, therefore, we have not yet adopted the new guidance. We are currently evaluating the impact of ASU 2020-04 on the consolidated financial statements, which we will adopt upon the first modification to our debt agreements.

In December 2019, the FASB issued ASU No. 2019-12 “Simplifying the Accounting for Income Taxes (Topic 740)” (“ASU 2019-12”), which simplifies the accounting for income taxes by eliminating certain exceptions to the guidance in Accounting Standards Codification (“ASC”) 740 related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. The standard also simplifies aspects of the accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. ASU 2019-12 will be effective for public entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020, however early adoption is permitted. We will follow all applicable changes as required as of January 1, 2021, the effective date, and no changes are necessary to earlier periods.

- Definition

The entire disclosure for change in accounting principle. Includes, but is not limited to, nature, reason, and method of adopting amendment to accounting standards or other change in accounting principle.

Basis of Presentation and Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2020

Accounting Policies [Abstract]

Nature of Operations

Nature of Operations —RRD is a global, integrated communications provider enabling organizations to create, manage, deliver and optimize their multichannel marketing and business communications. We have a flexible and comprehensive portfolio of integrated communications solutions that allows our clients to engage audiences, reduce costs and drive revenues. Our innovative content management offering, production platform, supply chain management, outsourcing capabilities and customized consultative expertise assist our clients in the delivery of integrated messages across multiple media to highly targeted audiences at optimal times for clients in virtually every private and public sector.

Use of Estimates

Use of Estimates —The preparation of consolidated financial statements, in conformity with GAAP, requires the extensive use of management’s estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the 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, allowance for credit losses, inventory obsolescence, asset valuations and useful lives, employee benefits, self-insurance reserves, taxes, restructuring and other provisions and contingencies.

Foreign Operations

Foreign Operations —Assets and liabilities denominated in foreign currencies are translated into U.S. dollars at the exchange rates 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 other comprehensive income (loss) while transaction gains and losses are recorded in net income (loss). Deferred taxes are not provided on cumulative foreign currency translation adjustments when we expect foreign earnings to be permanently reinvested.

Fair Value Measurements

Fair Value Measurements —Certain assets and liabilities are required to be recorded at fair value on a recurring basis. 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. We record the fair value of our foreign currency contracts, available-for-sale securities, interest rate swaps, pension plan assets and other postretirement benefits (“OPEB”) plan assets on a recurring basis. Assets measured at fair value on a nonrecurring basis include long-lived assets held and used, long-lived assets held for sale, goodwill and other intangible assets. The fair value of cash, cash equivalents, restricted cash, accounts receivable, short-term debt and accounts payable approximate their carrying values. The three-tier value hierarchy, which prioritizes valuation methodologies based on the reliability of the inputs, is:

Level 1 —Valuations based on quoted prices for identical assets and liabilities in active markets.

Level 2 —Valuations based on observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data.

Level 3 —Valuations based on unobservable inputs reflecting our own assumptions, consistent with reasonably available assumptions made by other market participants.

Net Sales

Net Sales - We have historically presented Sales and Cost of Sales for products and services separately in the Consolidated Statement of Operations and related disclosures. Sales from services became immaterial in relation to Net Sales in the third quarter of 2020 when adjusted by the effect of the activity of the Logistics business now presented in discontinued operations. Accordingly, we now present sales from products and services together within Net Sales in the Consolidated Statement of Operations and related disclosures. Refer to Note 18 – Segment and Geographic Area Information for further details.

Cash, Cash Equivalents and Restricted Cash

Cash and cash equivalents —We consider all highly liquid investments with original maturities of three months or less to be cash equivalents. Short-term securities consist of investment grade instruments of governments, financial institutions and corporations.

Restricted cash —Restricted cash primarily includes amounts related to letters of credit and bank acceptance drafts and amounts received in escrow in connection with the sale of DLS Worldwide (Refer to Note 2 – Discontinued Operations in the Consolidated Financial Statements).

The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the Consolidated Balance Sheets that sum to the total of the same such amounts shown in the Consolidated Statement of Cash Flows.

	December 31,
	2020		2019
Cash and cash equivalents	$	288.8	$	191.9
Restricted cash - current^(a)		62.6		32.9
Restricted cash - noncurrent^(b)		6.2		0.1
Total cash, cash equivalents and restricted cash	$	357.6	$	224.9

(a)	Included within Prepaid expenses and other current assets within the Consolidated Balance Sheets.

(b)	Included within Other noncurrent assets within the Consolidated Balance Sheets.

Receivables and Allowance for Credit Losses

Receivables and Allowance for Credit Losses —Receivables are stated net of allowances for credit losses and primarily include trade receivables, notes receivable and miscellaneous receivables from suppliers. No single client comprised more than 10% of our consolidated net sales in 2020, 2019 or 2018. We recognize an allowance for credit losses for financial assets carried at amortized cost to present the net amount expected to be collected as of the balance sheet date. Such allowance is based on credit losses expected to arise over the life of the asset’s contractual term, which includes consideration of prepayments. Assets are written off when we determine that such financial assets are deemed uncollectible and are recognized as a deduction from the allowance for credit losses. Expected recoveries of amounts previously written off, not to exceed the aggregate of the amount previously written off, are included in determining the necessary reserve at the balance sheet date. We pool financial assets based on similar risk characteristics to estimate expected credit losses. We estimate expected credit losses on financial assets individually when those assets do not share similar risk characteristics. We closely monitor our accounts receivable including timely account reconciliations, detailed reviews of past due accounts, updated credit limits, and monthly analysis of the adequacy of our reserve for credit losses. Specific client provisions are made when a review of significant outstanding amounts, utilizing information about client creditworthiness and current economic trends, indicates that collection is doubtful. In addition, provisions are made at differing rates, based upon the age of the receivable and our historical collection experience.

We utilize a loss rate approach to determine lifetime expected credit losses for our financial assets. This method is used for calculating an estimate of losses based primarily on our historical loss experience. In determining loss rates, we evaluate information related to historical losses, adjusted for current conditions and further adjusted for the period of time that we can reasonably forecast. We have concluded that we can reasonably support a forecast period for the contractual life of our financial assets. Qualitative and quantitative adjustments related to current conditions and the reasonable and supportable forecast period consider the following: the customer or vendor’s creditworthiness, changes in our policy and procedures to establish customer credit limits, changes in the payment terms of receivables, existence and effect of any concentration of credit and changes in the level of such concentrations, and the effects of other external forces such as the current and forecasted direction of the economic and business environment. We have considered the current and expected economic and market conditions as a result of COVID-19 in determining credit loss expense for the period ended December 31, 2020.

Transactions affecting the allowance for credit losses for financial instruments during the years ended December 31, 2020 and 2019 were as follows. Recoveries were immaterial for the years ended December 31, 2020 and 2019.

	2020			2019
Balance, beginning of year	$	14.3		$	19.6
Additional allowance recognized due to adoption of Topic ASC 326		0.3			—
Credit loss expense		5.7			3.3
Write-offs and other		(4.4	)		(8.6	)
Balance, end of year	$	15.9		$	14.3

Inventories

Inventories —Inventories include material, labor and factory overhead and are stated at the lower of cost or market and net of excess and obsolescence reserves for raw materials and finished goods. Provisions for excess and obsolete inventories are made at differing rates, utilizing historical data and current economic trends, based upon the age and type of the inventory. Specific excess and obsolescence provisions are also made when a review of specific balances indicates that the inventories will not be utilized in production or sold. The cost of 36.6% and 37.9% of the inventories at December 31, 2020 and 2019, respectively, has been determined using the Last-In, First-Out (LIFO) method. This method is intended to reflect the effect of inventory replacement costs within results of operations; accordingly, charges to cost of sales generally reflect recent costs of material, labor and factory overhead. We use an external-index method of valuing LIFO inventories. The remaining inventories, primarily related to certain acquired and international operations, are valued using the First-In, First-Out or specific identification methods.

The components of inventories, net of excess and obsolescence reserves for raw materials and finished goods, at December 31, 2020 and 2019 were as follows:

	2020			2019
Raw materials and manufacturing supplies	$	147.3		$	139.4
Work in process		64.8			64.6
Finished goods		107.9			116.4
LIFO reserve		(17.9	)		(18.6	)
Total	$	302.1		$	301.8

Long-Lived Assets

Long-Lived Assets —We assess potential impairments to our long-lived assets if events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. An impaired asset is written down to its estimated fair value based upon the most recent information available. Estimated fair value is generally measured by discounting estimated future cash flows. Long-lived assets, other than goodwill and other intangible assets, which are held for sale, are recorded at the lower of the carrying value or the fair value less the estimated cost to sell.

Property, Plant and Equipment

Property, Plant and Equipment —Property, plant and equipment are recorded at cost and depreciated on a straight-line basis over their estimated useful lives. Useful lives range from 15 to 40 years for buildings, the lesser of 7 years or the lease term for leasehold improvements and generally from 3 to 15 years for machinery and equipment. Maintenance and repair costs are charged to expense as incurred. Major overhauls that extend the useful lives of existing assets are capitalized. When properties are retired or disposed, the costs and accumulated depreciation are eliminated and the resulting profit or loss is recognized in the results of operations.

The components of property, plant and equipment at December 31, 2020 and 2019 were as follows:

	2020			2019
Land	$	38.2		$	47.8
Buildings		361.0			379.5
Machinery and equipment		1,703.1			1,702.0
		2,102.3			2,129.3
Accumulated depreciation		(1,663.5	)		(1,629.9	)
Total	$	438.8		$	499.4

During the years ended December 31, 2020, 2019 and 2018, depreciation expense was $100.8 million, $115.5 million, and $125.2 million, respectively.

During the fourth quarter of 2017, we entered into an agreement to sell a printing facility in Shenzhen, China and transfer the related land use rights. As of December 31, 2020, we have received deposits in accordance with the terms of the agreement of approximately $123.3 million which is recorded in other noncurrent liabilities on the Consolidated Balance Sheets. As of December 31, 2020, the carrying cost of the building and land use rights is recorded in other noncurrent assets and is not material. Additional deposits will be paid to us in accordance with the agreement. Gross proceeds from the sale are expected to be approximately $250.0 million, subject to changes in the exchange rate, and we expect the transaction to close in 2022 after closing conditions are satisfied and government approvals are obtained. Our contract with the buyer requires them to pay the final installment in 2022 even if the government’s approval is further delayed. If the buyer fails to comply with terms of the agreement or terminates for any reason, the Company is entitled to retain 30% of the purchase price as liquidated damages.

Goodwill

Goodwill —Goodwill is reviewed for impairment annually 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.

For certain reporting units, we may perform a qualitative, rather than quantitative, assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. In performing this qualitative analysis, we consider various factors, including the excess of prior year estimates of fair value compared to carrying value, the effect of market or industry changes and the reporting units’ actual results compared to projected results. Based on this qualitative analysis, if we determine that it is more likely than not that the fair value of the reporting unit is greater than its carrying value, no further impairment testing is performed.

For the remaining reporting units, we compare each reporting unit’s fair value, estimated based on comparable company market valuations and expected future discounted cash flows to be generated by the reporting unit, to its carrying value. See Note 6, Goodwill and Other Intangible Assets, for further discussion.

Amortization

Amortization —Certain costs to acquire and develop internal-use computer software are capitalized and amortized over their estimated useful life using the straight-line method, up to a maximum of five years. Amortization expense, primarily related to internally-developed software and excluding amortization expense related to other intangible assets, was $26.1 million, $29.4 million and $27.4 million for the years ended December 31, 2020, 2019 and 2018, respectively. Deferred debt issuance costs are amortized over the term of the related debt. Other intangible assets are recognized separately from goodwill and are amortized over their estimated useful lives. See Note 6, Goodwill and Other Intangible Assets, for further discussion of other intangible assets and the related amortization expense.

Financial Instruments

Financial Instruments —We use derivative financial instruments to hedge exposures to foreign exchange fluctuations in the ordinary course of business and to hedge the interest rate exposure on certain floating-rate debt.

All derivatives are recorded as other current or noncurrent assets or other current or noncurrent liabilities on the balance sheet at their respective fair values with unrealized gains and losses recorded in other comprehensive income (loss), net of applicable income taxes, or in the results of operations, depending on the purpose for which the derivative is held. For derivatives designated and that qualify as fair value hedges, the gain or loss on the derivative, as well as the offsetting gain or loss on the hedged item attributable to the hedged risk, are recognized in the results of operations. Changes in the fair value of derivatives that do not meet the criteria for designation as a hedge at inception, or fail to meet the criteria thereafter, are recognized currently in the results of operations. At inception of a hedge transaction, we formally document the hedge relationship and the risk management objective for undertaking the hedge. In addition, we assess, both at inception of the hedge and on an ongoing basis, whether the derivative in the hedging transaction has been highly effective in offsetting changes in fair value of the hedged item and whether the derivative is expected to continue to be highly effective. The impact of any ineffectiveness is recognized currently in the results of operations.

Our foreign currency contracts and interest rate swaps are subject to master netting agreements that allow us to settle positive and negative positions with the respective counterparties. Under these master netting agreements, net settlement generally permits us or the counterparty to determine the net amount payable for contracts due on the same date and in the same currency for similar types of derivative transactions. The master netting agreements generally also provide for net settlement of all outstanding contracts with a counterparty in the case of an event of default or a termination event. See Note 13, Derivatives, for additional information.

Share-Based Compensation

Share-Based Compensation —We recognize share-based compensation expense based on estimated fair values for all share-based awards made to employees and directors, including stock options, restricted stock units and performance share units. We recognize compensation expense for share-based awards expected to vest on a straight-line basis over the requisite service period of the award based on their grant date fair value. See Note 16, Stock and Incentive Programs for Employees and Directors, for further discussion.

Preferred Stock

Preferred Stock —We have two million shares of $1.00 par value preferred stock authorized for issuance. The Board of Directors may divide the preferred stock into one or more series and fix the redemption, dividend, voting, conversion, sinking fund, liquidation and other rights. We have no present plans to issue any preferred stock. We have reserved 0.2 million preferred stock shares for issuance under the Stockholder Rights Plan discussed in Note 17.

Pension and OPEB Plans

Pension and OPEB Plans —We record annual income and expense amounts relating to our pension and OPEB plans based on calculations which include various actuarial assumptions, including discount rates, mortality, assumed rates of return, compensation increases, turnover rates and healthcare cost trend rates. We review our actuarial assumptions on an annual basis and make modifications to the assumptions based on current rates and trends when it is deemed appropriate to do so. The effect of modifications on the value of plan obligations and assets is recognized immediately within other comprehensive income (loss) and amortized into operating earnings over future periods. We believe that the assumptions utilized in recording our obligations under our plans are reasonable based on our experience, market conditions and input from our actuaries and investment advisors. See Note 10, Retirement Plans, for additional information.

Taxes on Income

Taxes on Income —Deferred taxes are provided using an asset and liability method whereby deferred tax assets are recognized for deductible temporary differences and operating loss carryforwards and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax basis. Deferred tax assets are reduced by a valuation allowance when, in our opinion, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment.

We recognize deferred tax liabilities related to taxes on certain foreign earnings that were not considered to be permanently reinvested. No deferred tax liabilities were recognized for foreign earnings that were considered to be permanently reinvested. We regularly evaluate whether foreign earnings are expected to be permanently reinvested. This evaluation requires judgment about our future operating and liquidity needs. Changes in economic and business conditions, foreign or U.S. tax laws, or our financial situation could result in changes to these judgments and the need to record additional tax liabilities.

We are regularly audited by foreign and domestic tax authorities. These audits occasionally result in proposed assessments where the ultimate resolution might result in us owing additional taxes, including in some cases, penalties and interest. We recognize a tax position in our financial statements when it is more likely than not (i.e., a likelihood of more than fifty percent) 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 greater than fifty percent likely of being realized upon ultimate settlement. Although we believe that our estimates are reasonable, the final outcome of uncertain tax positions may be materially different from that which is reflected in our financial statements. We adjust such reserves upon changes in circumstances that would cause a change to the estimate of the ultimate liability, upon effective settlement or upon the expiration of the statute of limitations, in the period in which such event occurs. See Note 11, Income Taxes, for further discussion.

Revenue Recognition

All revenue recognized in the Consolidated Statements of Operations is considered to be revenue from contracts with clients according to Subtopic 606, which we adopted on January 1, 2018.

Disaggregation of Revenue

The following table presents net sales disaggregated by products and services:

	2020		2019		2018
Commercial print	$	1,357.7	$	1,694.5	$	1,935.6
Packaging		687.6		668.5		672.0
Direct marketing		555.4		676.7		581.6
Labels		496.6		497.4		481.4
Statements		441.6		545.4		584.2
Digital print and fulfillment		425.7		492.1		474.4
Supply chain management		329.9		298.7		321.0
Forms		202.4		244.3		267.5
Business process outsourcing		169.4		243.9		259.6
Digital and creative solutions		100.0		111.7		125.1
Total net sales	$	4,766.3	$	5,473.2	$	5,702.4

Revenue for commercial print, direct marketing, packaging, statements, labels, digital print and fulfillment, supply chain management and forms is primarily recognized at a point in time. We generally recognize revenue for these products upon the transfer of control of the products to the client which typically occurs upon transfer of title and risk of ownership, which is generally upon shipment to the client. For certain products, we are able to recognize revenue for completed inventory billed but not yet shipped at the client’s direction. Revenue for business process outsourcing and digital and creative solutions is recognized over time or at a point in time, depending on the nature of the service which could be either recurring or project-based.

The following is a description of our products and services:

Commercial Print

We generate revenue by providing various commercial printing products and offer a full range of branded materials including manuals, publications, brochures, business cards, flyers, post cards, posters and promotional items.

Direct Marketing

We generate revenue by providing audience segmentation, creative development, program testing, print production, postal optimization and performance analytics for large-scale personalized direct mail programs.

Packaging

We generate revenue by providing packaging solutions, ranging from rigid boxes to in-box print materials, for clients in healthcare and life sciences, consumer electronics, cosmetics and consumer packaged goods industries.

Statements

We generate revenue by creating critical business communications, including customer billings, financial statements, healthcare communications and insurance documents. Our capabilities include design and composition, variable imaging, email, archival and digital mail interaction, as well as our innovative RRDigital solution set.

Labels

We generate revenue by producing custom labels for clients across multiple industries including warehouse and distribution, retail, pharmaceutical, manufacturing and consumer packaging. We offer distribution and shipping labels, healthcare and durable goods labels, promotional labels and consumer product goods packaging labels.

Digital Print and Fulfillment

We generate revenue by providing in-store marketing materials, including signage and point-of-purchase materials, as well as custom marketing kits that require multiple types of marketing collateral. Under the trade name Motif^TM, we also create custom photobooks.

Supply Chain Management

We generate revenue by providing workflow design to assembly, configuration, kitting and fulfillment for clients in life sciences and healthcare, consumer electronics, telecommunications, cosmetics, education and industrial industries.

Forms

We generate revenue by producing a variety of forms including invoices, order forms and business forms that support both the private and public sectors for clients in financial, government, retail, healthcare and business services industries.

Business Process Outsourcing

We generate revenue by providing outsourcing services including creative services, research and analytics, financial management and other services for legal providers, insurance, telecommunications, utilities, retail and financial services companies.

Digital and Creative Solutions

We generate revenue by creating and managing content for delivery across multiple marketing communications channels including print and digital advertising, direct marketing and mail, packaging, sales collateral, in-store marketing and social media.

Variable Consideration

Certain clients may receive volume-based rebates or early payment discounts, which are accounted for as variable consideration. We estimate these amounts based on the expected amount to be earned by our clients and reduce revenue accordingly. We do not expect significant changes to estimates of variable consideration. Given the nature of our products and the history of returns, product returns are not significant.

Contract Balances

The following table provides information about contract assets and liabilities from contracts with clients:

	Contract Liabilities
	Short-Term		Long-Term
Balance at January 1, 2020	$	18.9	$	0.2
Balance at December 31, 2020		15.6		—

Contract liabilities primarily relate to client advances received prior to completion of performance obligations. Reductions in contract liabilities are a result of our completion of performance obligations. Revenue recognized during the year ended December 31, 2020 from amounts included in contract liabilities at the beginning of the period was approximately $16.9 million.

Practical Expedients and Exemptions

As part of the adoption of Topic 606, we have elected practical expedients and exemptions allowable under the guidance.

We account for shipping and handling activities performed after the control of a good has been transferred to the client as a fulfillment cost. We accrue for the costs of shipping and handling activities if revenue is recognized before contractually agreed shipping and handling activities occur.

We apply Topic 606 to a portfolio of contracts (or performance obligations) with similar characteristics as we reasonably expect that the effects on the financial statements of applying this guidance to the portfolio would not differ significantly from applying this guidance to the individual contracts (or performance obligations) within that portfolio.

When the output method for measure of progress is determined appropriate, we recognize revenue in the amount for which we have the right to invoice for revenue that is recognized over time and for which we can demonstrate that the invoiced amount corresponds directly with the value to the client for the performance completed to date.

We generally expense sales commissions and other costs to obtain a contract when incurred, because the amortization period would have been one year or less. These costs are recorded within Selling, general and administrative expenses.

We exclude sales taxes and other similar taxes from the measurement of the transaction price. We do not disclose the value of unsatisfied performance obligations, nor do we disclose the timing of revenue recognition for contracts with an original expected length of one year or less.

Summary of Results and Assets and Liabilities of Discontinued Operations

Results of discontinued operations were as follows:

	Twelve Months Ended
	December 31,
	2020			2019			2018
Net sales	$	632.5		$	865.7		$	1,203.8
Cost of sales		(548.6	)		(758.7	)		(1,070.5	)
Selling, general, administrative and other operating expenses		(66.2	)		(95.1	)		(109.6	)
Restructuring, impairment and other expense		(21.1	)		(98.6	)		(0.2	)
Operating income (loss) from discontinued operations		(3.4	)		(86.7	)		23.5
Income tax expense		(0.9	)		1.7			3.2
Net income (loss) from discontinued operations	$	(2.5	)	$	(88.4	)	$	20.3

Restructuring, impairment, and other expenses included $20.6 million and $98.5 million of non-cash charges related to impairment of goodwill recorded in 2020 and 2019 respectively.

Our evaluation of goodwill for impairment involves the comparison of the fair value of each reporting unit to its carrying value. If the carrying value of a reporting unit exceeds its estimated fair value, an impairment loss is recognized equal to the excess, limited to the total amount of goodwill allocated to that reporting unit. The Company determines the fair value of its reporting units using a combination of comparable company market valuations and expected future discounted cash flows.

During the first quarter of 2020, we identified a triggering event at our Logistics reporting unit. We determined that the fair value of our Logistics reporting unit was lower than its carrying value, resulting in a goodwill impairment charge of $20.6 million. The goodwill impairment charge resulted from reductions in the estimated fair value for this reporting unit based on lower expectations for future revenue, profitability and cash flows driven by expected reduced demand due to the COVID-19 pandemic. The goodwill impairment charge was determined using discounted cash flow analysis and comparable marketplace fair value data which utilized Level 3 inputs including forecasted future revenue and the selection of the discount rate.

Assets and liabilities of discontinued operations presented in the Consolidated Balance Sheets as of December 31, 2019 include the following:

	December 31, 2019
Receivables, net of allowance	$	120.6
Operating lease right-of-use assets		8.8
Goodwill		53.3
Intangible assets, net		10.9
Other assets		7.0
Total assets of discontinued operations	$	200.6


Accounts payable	$	53.3
Accrued expenses and other liabilities		38.8
Total liabilities of discontinued operations	$	92.1
