Amendment Description	EXPLANATORY NOTE Unisys Corporation is filing this Amendment No. 1 on Form 10-K/A (this amendment) to its Annual Report on Form 10-K for the year ended December 31, 2021, originally filed with the Securities and Exchange Commission (SEC) on February 22, 2022 (the original filing) to address management’s re-evaluation of disclosure controls and procedures and to reflect the identification of material weaknesses in the company’s disclosure controls and procedures and internal control over financial reporting. The material weaknesses did not result in any change to the company’s consolidated financial statements as set forth in the original filing. This amendment is limited in scope to make the following changes to the original filing: • To amend Part II - Item 9A. Controls and Procedures related to the effectiveness of our disclosure controls and procedures. • To amend Part I - Item 1A. Risk Factors to add an additional risk factor regarding the potential adverse impact that the failure to remediate the material weaknesses could have on our timely and accurate reporting of financial results and to amend a risk factor in the original filing regarding the potential adverse impacts of cybersecurity incidents and vulnerabilities. • To amend Part II - Item 8. Financial Statements and Supplementary Data to restate (i) Management’s Report on Internal Control Over Financial Reporting, and (ii) the Report of Independent Registered Public Accounting Firm, on the company’s internal control over financial reporting as of December 31, 2021. • To amend Part IV - Item 15. Exhibits and Financial Statement Schedules to include currently dated (i) auditor consents, which are filed herewith as Exhibits 23.1 and 23.2 and (ii) certifications from the company’s Principal Executive Officer and Principal Financial Officer as required by Sections 302 and 906 of the Sarbanes Oxley Act of 2002, which certifications are filed herewith as Exhibits 31.1, 31.2, 32.1 and 32.2. This amendment has not been updated or amended to give effect to any subsequent events beyond those that existed as of the original filing date and should thus be read in conjunction with the original filing and any of the company’s other filings with the SEC subsequent to the original filing, together with any amendments to those filings. Other than the filing of the information identified above, this amendment does not modify or update the disclosure in the original filing in any way.

Accounting Policies [Abstract]

Summary of significant accounting policies

Note 1 — Summary of significant accounting policies

Principles of consolidation

The consolidated financial statements include the accounts of all majority-owned subsidiaries.

Use of estimates

The preparation of financial statements in conformity with generally accepted accounting principles in the United States of America (GAAP) requires management to make estimates and assumptions about future events. These estimates and assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities and the reported amounts of revenue and expenses. Such estimates include the valuation of estimated credit losses, contract assets, operating lease

right-of-use

assets, outsourcing assets, marketable software, goodwill, purchased intangibles and other long-lived assets, legal contingencies, assumptions used in the calculation for systems integration projects, income taxes and retirement and other post-employment benefits, among others. These estimates and assumptions are based on management’s best estimates and judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. Management adjusts such estimates and assumptions when facts and circumstances dictate. As future events and their effects cannot be determined with precision, actual results could differ materially from these estimates. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods.

The company assessed certain accounting matters that generally require consideration of forecasted financial information in context with the information reasonably available to us and the unknown future impacts of

COVID-19

as of December 31, 2021 and through the date of this report. The accounting matters assessed included, but were not limited to the valuation of estimated credit losses, contract assets, outsourcing assets, marketable software, deferred tax assets, goodwill, purchased intangibles and other long-lived assets, and retirement and other post-employment benefits. While there was not a material impact to our consolidated financial position as of December 31, 2021 resulting from our assessments, our future assessment of our current expectations at that time of the future impacts and duration of

COVID-19,

as well as other factors, could result in material impacts to our consolidated financial position in future reporting periods.

Cash and Cash equivalents

Cash and cash equivalents consist of cash on hand, short-term investments purchased with an original maturity of three months or less and certificates of deposit which may be withdrawn at any time at the discretion of the company without penalty. Cash and cash equivalents subject to contractual restrictions and not readily available are classified as restricted cash.

The following table provides a reconciliation of cash and cash equivalents and restricted cash reported within the consolidated balance sheets to the total of the amounts shown in the consolidated statements of cash flows.


As of December 31,	2021		2020
Cash and cash equivalents	$	552.9	$	898.5
Restricted cash		7.7		8.2

Total cash, cash equivalents and restricted cash shown in the consolidated statements of cash flows	$	560.6	$	906.7

Inventories

Inventories are valued at the lower of cost and net realizable value. Cost is determined on the

first-in,

first-out

method.

Properties

Properties are carried at cost and are depreciated over the estimated lives of such assets using the straight-line method. The estimated lives used, in years, are as follows: buildings, 20 – 50; machinery and office equipment, 4 – 7; rental equipment, 4; and

internal-use

software, 3 – 10.

Outsourcing assets

Costs of outsourcing contracts are generally expensed as incurred. However, certain costs incurred upon initiation of an outsourcing contract (principally initial customer setup) are deferred and expensed over the initial contract life. Fixed assets and software used in connection with outsourcing contracts are capitalized and depreciated over the shorter of the initial contract life or in accordance with the fixed asset policy described above.

Recoverability of these costs is subject to various business risks. Quarterly, the company compares the carrying value of these assets with the undiscounted future cash flows expected to be generated by them to determine if there is impairment. If impaired, these assets are reduced to an estimated fair value on a discounted cash flow basis. The company prepares its cash flow estimates based on assumptions that it believes to be reasonable but are also inherently uncertain. Actual future cash flows could differ from these estimates. The gross amount of outsourcing assets totaled $568.3 million and $692.1 million as of December 31, 2021 and 2020, respectively, and related accumulated amortization totaled $443.7 million and $518.2 million as of December 31, 2021 and 2020, respectively.

Marketable software

The cost of development of computer software to be sold or leased, incurred subsequent to establishment of technological feasibility, is capitalized and amortized to cost of sales over the estimated revenue-producing lives of the products. For the company’s proprietary enterprise software products, the amortization period is five years following product release, and for the remaining products, the amortization period is three years following product release. In assessing the estimated revenue-producing lives and recoverability of the products, the company considers operating strategies, underlying technologies utilized, estimated economic life and external market factors, such as expected levels of competition, barriers to entry by potential competitors, stability in the market and governmental regulation. The company continually reassesses the estimated revenue-producing lives of the products and any change in the company’s estimate could result in the remaining amortization expense being accelerated or spread out over a longer period. As of December 31, 2021, the company believes that all unamortized costs are fully recoverable. The gross amount of marketable software totaled $2,266.1 million and $2,219.4 million as of December 31, 2021 and 2020, respectively, and related accumulated amortization totaled $2,089.9 million and $2,025.8 million as of December 31, 2021 and 2020, respectively.

Internal-use

software

The company capitalizes certain internal and external costs incurred to acquire or create

internal-use

software, principally related to software coding, designing system interfaces, and installation and testing of the software. These costs are amortized in accordance with the fixed asset policy described above.

Goodwill and Purchased Intangible Assets

Goodwill arising from the acquisition of an entity represents the excess of the purchase price consideration over the fair value of the underlying identifiable intangible assets and net assets or liabilities assumed. Goodwill is initially recognized as an asset and is subsequently measured at cost less any accumulated impairment losses.

The company tests goodwill for impairment annually in the fourth quarter using data as of September 30 of that year, as well as whenever there are events or changes in circumstances (triggering events) that would more likely than not reduce the fair value of one or more reporting units below its respective carrying amount. The company initially assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. This qualitative assessment considers all relevant factors specific to the reporting units, including macroeconomic conditions, industry and market considerations, overall financial performance, and relevant entity-specific events.

If the company determines that it is not more likely that the carrying amount for a reporting unit is less than its fair value, then subsequent quantitative goodwill impairment testing is not required. If the company determines that it is more likely than not that the carrying amount for a reporting unit is greater than its fair value, then it proceeds with a subsequent quantitative goodwill impairment test. Under the quantitative test, the company compares the fair value of each of its reporting units to their respective carrying value. If the carrying value exceeds fair value, an impairment charge is recognized for the difference. Impaired goodwill is written down to its fair value through a charge to the consolidated statement of income (loss) in the period the impairment is identified.

In January 2021, the company changed its organizational structure to more effectively address evolving client needs. With these changes, the company changed its reportable segments, operating segments and reporting units. The realignment and change was deemed a triggering event, resulting in the company performing an interim quantitative goodwill impairment test on the reporting units impacted by this segment change as of immediately before and immediately after the change. There were no impairment charges resulting from this analysis. See Note 21, “Segment information” for additional information on the company’s operating and reportable segments.

During the fourth quarter of 2021, the company performed its annual qualitative goodwill assessment and determined it was not necessary to perform the quantitative goodwill impairment test.

When the company performs the quantitative goodwill impairment test for a reporting unit, it estimates the fair value of the reporting unit using both the income approach and the market approach.

The income approach incorporates the use of a discounted cash flow method in which the estimated future cash flows and terminal values for each reporting unit are discounted to present value. Cash flow projections are based on management’s estimates of economic and market conditions, which drive key assumptions of revenue growth rates, operating margins, capital expenditures and working capital requirements. The discount rate in turn is based on various market factors and specific risk characteristics of each reporting unit.

The market approach estimates fair value by applying performance metric multiples to the reporting unit’s prior and expected operating performance. The multiples are derived from comparable publicly traded companies with similar operating and investment characteristics as the reporting unit.

If the fair value of the reporting unit derived using the income approach is significantly different from the fair value estimate using the market approach, the company reevaluates its assumptions used in the two models. When considering the weighting between the market approach and income approach, the company gives more weighting to the income approach. The higher weighting assigned to the income approach takes into consideration that the guideline companies used in the market approach generally represent larger diversified companies relative to the reporting units and may have different long-term growth prospects, among other factors.

In order to assess the reasonableness of the calculated reporting unit fair values, the company also compares the sum of the reporting units’ fair values to its market capitalization (per share stock price multiplied by shares outstanding) and calculates an implied control premium (the excess of the sum of the reporting units’ fair values over the market capitalization).

Estimating the fair value of reporting units requires the use of estimates and significant judgments that are based on a number of factors including actual operating results. It is reasonably possible that the judgments and estimates described above could change in future periods.

Finite-lived intangible assets purchased in a business combination are recorded at fair value and amortized to selling, general and administrative expense over their estimated useful lives. Finite-lived intangible assets are tested for impairment whenever events or changes in circumstances would indicate that the carrying value may not be recoverable. An impairment charge would be recognized if the carrying value exceeds fair value in the consolidated statement of income (loss) in the period the impairment is identified.

Retirement benefits

Accounting rules covering defined benefit pension plans and other postretirement benefits require that amounts recognized in financial statements be determined on an actuarial basis. Management develops the actuarial assumptions used by its U.S. and international defined benefit pension plan obligations based upon the circumstances of each particular plan. The determination of the defined benefit pension plan obligations requires the use of estimates. A significant element in determining the company’s retirement benefits expense or income is the expected long-term rate of return on plan assets. This expected return is an assumption as to the average rate of earnings expected on the funds invested or to be invested to provide for the benefits included in the projected pension benefit obligation. The company applies this assumed long-term rate of return to a calculated value of plan assets, which recognizes changes in the fair value of plan assets in a systematic manner over four years. This produces the expected return on plan assets that is included in retirement benefits expense or income. The difference between this expected return and the actual return on plan assets is deferred. The net deferral of past asset losses or gains affects the calculated value of plan assets and, ultimately, future retirement benefits expense or income.

At December 31 of each year, the company determines the fair value of its retirement benefits plan assets as well as the discount rate to be used to calculate the present value of plan liabilities. Management’s significant assumption used in the determination of the defined benefit pension plan obligations, and settlement losses associated with respect to the U.S. pension plans, is the discount rate. Inherent in deriving the discount rate are significant assumptions with respect to the timing and magnitude of expected benefit payment obligations. The discount rate is an estimate of the interest rate at which the retirement benefits could be effectively settled. In estimating the discount rate, the company looks to rates of return on high-quality, fixed-income investments currently available and expected to be available during the period to maturity of the retirement benefits. The company uses a portfolio of fixed-income securities, which receive at least the second-highest rating given by a recognized ratings agency.

Noncontrolling interest

The company owns a

fifty-one

percent interest in Intelligent Processing Solutions Ltd. (iPSL), a U.K. business process outsourcing joint venture. The remaining interests, which are reflected as a noncontrolling interest in the company’s financial statements, are owned by three financial institutions for which iPSL performs services.

Revenue recognition

Revenue is recognized at an amount that reflects the consideration to which the company expects to be entitled in exchange for transferring goods and services to a customer. The company determines revenue recognition using the following five steps: (1) identify the contract(s) with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when (or as) the company satisfies a performance obligation.

At contract inception, the company assesses the goods and services promised in a contract with a customer and identifies as a performance obligation each promise to transfer to the customer either: (1) a good or service (or a bundle of goods or services) that is distinct or (2) a series of distinct goods or services that are substantially the same and that have the same pattern of transfer to the customer. The company recognizes revenue only when it satisfies a performance obligation by transferring a promised good or service to a customer.

The company must apply its judgment to determine the timing of the satisfaction of performance obligations as well as the transaction price and the amounts allocated to performance obligations including estimating variable consideration, adjusting the consideration for the effects of the time value of money and assessing whether an estimate of variable consideration is constrained.

Revenue from hardware sales is recognized upon the transfer of control to a customer, which is defined as an entity’s ability to direct the use of and obtain substantially all of the remaining benefits of an asset.

Revenue from software licenses is recognized at the inception of either the initial license term or the inception of an extension or renewal to the license term.

Revenue for operating leases is recognized on a monthly basis over the term of the lease and for sales-type leases at the inception of the lease term. Such revenue is not material to the company’s consolidated results of operations.

Revenue from equipment and software maintenance and post-contract support is recognized on a straight-line basis as earned over the terms of the respective contracts. Cost related to such contracts is recognized as incurred.

Revenue and profit under systems integration contracts are recognized over time as the company transfers control of goods or services. The company measures its progress toward satisfaction of its performance obligations using the

cost-to-cost

method, or when services have been performed, depending on the nature of the project. For contracts accounted for using the

cost-to-cost

method, revenue and profit recognized in any given accounting period are based on estimates of total projected contract costs. The estimates are continually reevaluated and revised, when necessary, throughout the life of a contract. Any adjustments to revenue and profit resulting from changes in estimates are accounted for in the period of the change in estimate. When estimates indicate that a loss will be incurred on a contract upon completion, a provision for the expected loss is recorded in the period in which the loss becomes evident. Revenue from such contracts is not material to the company’s consolidated results of operations.

In services arrangements, the company typically satisfies the performance obligation and recognizes revenue over time, because the client simultaneously receives and consumes the benefits provided as the company performs the services. The company’s services are provided on a

time-and-materials

basis, as a fixed-price contract or as a fixed-price per measure of output contract.

Revenue from

time-and-material

contracts is recognized on an output basis as labor hours are delivered.

In managed services, application management, business process outsourcing and other cloud-based services arrangements, the arrangement generally consists of a single performance obligation comprised of services that are substantially the same and that have the same pattern of transfer. The promise to transfer the individual services is not separately identifiable from other promises in the contracts and, therefore, is not distinct. The company applies a measure of progress (typically time-based) to any fixed consideration and allocates variable consideration to the periods of service, which are typically monthly or quarterly, based on usage. As a result, revenue is recognized over the period the services are provided either on a straight-line basis or on a usage basis, depending on the terms of the arrangement (such as whether the company is standing ready to perform or whether the contract has usage-based metrics). This results in revenue recognition that corresponds with the value to the client of the services transferred to date relative to the remaining services promised.

The company also enters into arrangements that may include any combination of hardware, software or services. For example, a client may purchase an enterprise server that includes operating system software. In addition, the arrangement may include post-contract support for the software and a contract for post-warranty maintenance for service of the hardware. These arrangements consist of multiple performance obligations, with control over hardware and software transferred in one reporting period and the software support and hardware maintenance services performed across multiple reporting periods. In another example, the company may provide desktop managed services to a client on a long-term multiple-year basis and periodically sell hardware and license software products to the client. The services are provided on a continuous basis across multiple reporting periods and control over the hardware and software products occurs in one reporting period.

The company allocates the total transaction price to be earned under an arrangement among the various performance obligations in proportion to their relative standalone selling prices. The standalone selling price for a performance obligation is the price at which the company would sell a promised good or service separately to a customer.

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. For contracts with multiple performance obligations, the company allocates the contract’s transaction price to each performance obligation using its best estimate of the standalone selling price of each distinct good or service in the contract. The primary methods used to estimate standalone selling price are as follows: (1) the expected cost plus margin approach, under which the company forecasts its expected costs of satisfying a performance obligation and then adds an appropriate margin for that distinct good or service and (2) the percent discount off of list price approach.

In the Digital Workplace Solutions (DWS) and the Cloud and Infrastructure Solutions (C&I) segments, substantially all of the company’s performance obligations are satisfied over time as work progresses and therefore substantially all of the revenue in this segment is recognized over time. The company generally receives payment for these contracts over time as the performance obligations are satisfied.

In the Enterprise Computing Solutions (ECS) segment, substantially all of the company’s sales of software and hardware are transferred to customers at a single point in time. Revenue on these contracts is recognized when control over the product is transferred to the customer or a software license term begins. The company generally receives payment for these contracts upon signature or within 30 to 60 days.

The company discloses disaggregation of its customer revenue by geographic areas by segment (see Note 21, “Segment information”).

The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled receivables, contract assets and deferred revenue (contract liabilities).

Revenue excludes taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue producing transaction and collected by the company from a customer (e.g., sales, use and value-added taxes). Revenue includes payments for shipping and handling activities.

Advertising costs

All advertising costs are expensed as incurred.

Shipping and handling

Costs related to shipping and handling are included in cost of revenue.

Stock-based compensation plans

Stock-based compensation represents the cost related to stock-based awards granted to employees and directors. Compensation expense for performance-based restricted stock and restricted stock unit awards is recognized as expense ratably for each installment from the date of the grant until the date the restrictions lapse and is based on the fair market value at the date of grant and the probability of achievement of the specific performance-related goals. Compensation expense for market-based awards is recognized as expense ratably over the measurement period, regardless of the actual level of achievement, provided the service requirement is met. The fair value of restricted stock and restricted stock units with time and performance conditions is determined based on the trading price of the company’s common shares on the date of grant. The fair value of awards with market conditions is estimated using a Monte Carlo simulation. The company recognizes compensation expense for the fair value of stock options, which have graded vesting, on a straight-line basis over the requisite service period. The expense is recorded in selling, general and administrative expenses.

Income taxes

Income taxes are based on income before taxes for financial reporting purposes and reflect a current tax liability for the estimated taxes payable in the current-year tax returns and changes in deferred taxes. Deferred tax assets or liabilities are determined based on differences between financial reporting and tax bases of assets and liabilities and are measured using enacted tax laws and rates. A valuation allowance is provided on deferred tax assets if it is determined that it is more likely than not that the asset will not be realized. The company releases the income tax effects of deferred tax balances that have a valuation allowance from accumulated other comprehensive income once the reason the tax effects were established ceases to exist (e.g., a postretirement plan is liquidated). The company recognizes penalties and interest accrued related to income tax liabilities in provision for income taxes in its consolidated statements of income (loss).

The company treats the global intangible

low-tax

income tax, or GILTI, as a period cost when included in U.S. taxable income, and the base erosion and anti-abuse tax, or BEAT, as a period cost when incurred.

Translation of foreign currency

The local currency is the functional currency for most of the company’s international subsidiaries, and as such, assets and liabilities are translated into U.S. dollars at

year-end

exchange rates. Income and expense items are translated at average exchange rates during the year. Translation adjustments resulting from changes in exchange rates are reported in other comprehensive income (loss). Exchange gains and losses are reported in other (expense), net.

For those international subsidiaries operating in highly inflationary economies, the U.S. dollar is the functional currency, and as such, nonmonetary assets and liabilities are translated at historical exchange rates, and monetary assets and liabilities are translated at current exchange rates. Exchange gains and losses arising from remeasurement are included in other (expense), net.

Fair value measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining fair value measurements for assets and liabilities required to be recorded at fair value, the company assumes that the transaction is an orderly transaction that assumes exposure to the market for a period before the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets or liabilities; it is not a forced transaction (for example, a forced liquidation or distress sale). The fair value hierarchy has three levels of inputs that may be used to measure fair value: Level 1 – Quoted prices (unadjusted) in active markets for identical assets or liabilities that the company can access at the measurement date; Level 2 – Inputs other than quoted prices within Level 1 that are observable for the asset or liability, either directly or indirectly; and Level 3 – Unobservable inputs for the asset or liability. The company has applied fair value measurements to its derivatives (see Note 13, “Financial instruments and concentration of credit risks”), long-term debt (see Note 16, “Debt”), and to its postretirement plan assets (see Note 18, “Employee plans”).

Accounting Changes and Error Corrections [Abstract]
Recent accounting pronouncements and accounting changes	Note 3 — Recent accounting pronouncements and accounting changes Effective January 1, 2020, the company adopted Accounting Standards Update (ASU) No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which removed certain exceptions 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 new standard was applied to the presentation of the company’s U.S. Federal business, which is reflected in discontinued operations. In October 2021, the Financial Accounting Standards Board issued ASU No. 2021-08, Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. This guidance requires that an acquirer recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with ASC 606, Revenue from Contracts with Customers, as if it had originated the contracts. Deferred revenue acquired in a business combination is no longer required to be measured at its fair value, which had historically resulted in a deferred revenue impairment at the date of acquisition. The amendment is effective January 1, 2023 and early adoption is permitted. The company expects to adopt this new guidance effective January 1, 2022.

Leases and commitments

Leases [Abstract]

Leases and commitments

Note 6 — Leases and commitments

Leases

The company determines if an arrangement is a lease at inception. This determination generally depends on whether the arrangement conveys to the company the right to control the use of an explicitly or implicitly identified asset for a period of time in exchange for consideration. Control of an underlying asset is conveyed to the company if the company obtains the rights to direct the use of and to obtain substantially all of the economic benefits from using the underlying asset. The company is the lessee in lease agreements that include lease and

non-lease

components, which the company accounts for as a single lease component for all personal property leases. The company also has lease agreements in which it is the lessor that include lease and

non-lease

components. For these agreements, the company accounts for these components as a single lease component. Lease expense for variable leases and short-term leases is recognized when the expense is incurred.

Operating leases are included in operating lease

right-of-use

(ROU) assets, other accrued liabilities and long-term operating lease liabilities on the consolidated balance sheets. Operating lease ROU assets and lease liabilities are recognized at the commencement date of the lease based on the present value of lease payments over the lease term. Operating lease payments are recognized as lease expense on a straight-line basis over the lease term.

Finance leases are included in outsourcing assets, net and long-term debt on the consolidated balance sheets. Finance lease ROU assets and lease liabilities are initially measured in the same manner as operating leases. Finance lease ROU assets are amortized using the straight-line method. Finance lease liabilities are measured at amortized cost using the effective interest method.

The company has not capitalized leases with terms of twelve months or less.

As most of the company’s leases do not provide an implicit rate, the company uses its incremental borrowing rate, based on the information available at the lease commencement date, in determining the present value of lease payments. The company determines the incremental borrowing rate using the portfolio approach considering lease term and lease currency.

The lease term for all of the company’s leases includes the

non-cancelable

period of the lease plus any additional periods covered by either a company option to extend (or not to terminate) the lease that the company is reasonably certain to exercise, or an option to extend (or not to terminate) the lease controlled by the lessor.

Lease payments included in the measurement of the lease liability are comprised of fixed payments, variable payments that depend on index or rate, amounts expected to be payable under a residual value guarantee and the exercise of the company option to purchase the underlying asset, if reasonably certain.

Variable lease payments associated with the company’s leases are recognized when the event, activity, or circumstance in the lease agreement on which those payments are assessed occurs. Variable lease payments are presented as an operating expense in the company’s consolidated results of operations in the same line item as expense arising from fixed lease payments (operating leases) or amortization of the ROU asset (finance leases).

The company uses the long-lived assets impairment guidance in ASC Subtopic

360-10

Property, Plant, and Equipment

to determine whether a ROU asset is impaired, and if so, the amount of the impairment loss to recognize. If impaired, ROU assets for operating and finance leases are reduced for any impairment losses.

The company monitors for events or changes in circumstances that require a reassessment of its leases. When a reassessment results in the remeasurement of a lease liability, a corresponding adjustment is made to the carrying amount of the corresponding ROU asset unless doing so would reduce the carrying amount of the ROU asset to an amount less than zero. In that case, the amount of the adjustment that would result in a negative ROU asset balance is recorded in the consolidated statement of income (loss).

The company has commitments under operating leases for certain facilities and equipment used in its operations. The company also has finance leases for equipment. The company’s leases generally have initial lease terms ranging from 1 year to 8 years, most of which include options to extend or renew the leases for up to 5 years, and some of which may include options to terminate the leases within 1 year. Certain lease agreements contain provisions for future rent increases.

During 2021, the company’s valuation allowance declined by $45.3 million principally due to the recognition of a net income tax expense of $(102.1) million including net tax benefit of $0.8 million, expired net operating losses/tax credits of $50.0 million, translation adjustments of $18.4 million and other activity of $79.0 million.

During 2020, the company’s valuation allowance declined by $253.2 million principally due to the recognition of a net income tax benefit of $189.0 million including net tax expense of $2.9 million, expired net operating losses/tax credits of $28.9 million, translation adjustments of $(20.9) million and other activity of $56.2 million.

The realization of the company’s net deferred tax assets as of December 31, 2021 is primarily dependent on the ability to generate sustained taxable income in various jurisdictions. Judgment is required to estimate forecasted future taxable income, which may be impacted by future business developments, actual results, strategic operational and tax initiatives, legislative, and other economic factors and developments. It is at least reasonably possible that the company’s judgment about the need for, and level of, existing valuation allowances could change in the near term based on changes in objective evidence such as further sustained income or loss in certain jurisdictions, as well as the other factors discussed above, primarily in certain jurisdictions outside of the United States. As such, the company will continue to monitor income levels and mix among jurisdictions, potential changes to the company’s operating and tax model, and other legislative or global developments in its determination. It is reasonably possible that such changes could result in a material impact to the company’s valuation allowance within the next 12 months. Any increase or decrease in the valuation allowance would result in additional or lower income tax expense in such period and could have a significant impact on that period’s earnings.

Under U.S. tax law, distributions from foreign subsidiaries to U.S. shareholders are generally exempt from taxation. Consequently, the deferred income tax liability on undistributed earnings is generally limited to any foreign withholding or other foreign taxes that will be imposed on such distributions. As the company currently intends to indefinitely reinvest the earnings of certain foreign subsidiaries, no provision has been made for income taxes that may become payable upon distribution of the earnings of such subsidiaries. The unrecognized deferred income tax liability at December 31, 2021 approximated $28.0 million.

Cash paid for income taxes, net of refunds was as follows:


Year ended December 31,	2021		2020		2019
Cash paid for income taxes, net of refunds	$	53.7	$	24.7	$	37.6

A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:


Year ended December 31,	2021			2020			2019
Balance at January 1	$	30.9		$	25.6		$	18.9
Additions based on tax positions related to the current year		3.5			8.5			11.1
Changes for tax positions of prior years		(8.8	)		(0.7	)		(0.6	)
Reductions as a result of a lapse of applicable statute of limitations		(2.6	)		(2.3	)		(2.3	)
Settlements		(0.3	)		(1.8	)		(1.1	)
Changes due to foreign currency		(1.1	)		1.6			(0.4	)

Balance at December 31	$	21.6		$	30.9		$	25.6

The company recognizes penalties and interest accrued related to income tax liabilities in the provision for income taxes in its consolidated statements of income (loss). At December 31, 2021 and 2020, the company had an accrual of $3.8 million and $3.9 million, respectively, for the payment of penalties and interest.

At December 31, 2021, all of the company’s liability for unrecognized tax benefits, if recognized, would affect the company’s effective tax rate. Within the next 12 months, the company believes that it is reasonably possible that the amount of unrecognized tax benefits may decrease by $1.9 million related to a statute of limitation expiration; however, various events could cause this belief to change in the future.

The company and its subsidiaries file income tax returns in the U.S. federal jurisdiction, and various states and foreign jurisdictions. Several U.S. state and foreign income tax audits are in process. The company is under an audit in India, for which years prior to 2007 are closed. For the most significant jurisdictions outside the U.S., the audit periods through 2016 are closed for Brazil, and the audit periods through 2017 are closed for the United Kingdom. All of the various ongoing income tax audits throughout the world are not expected to have a material impact on the company’s financial position.

Internal Revenue Code Sections 382 and 383 provide annual limitations with respect to the ability of a corporation to utilize its net operating loss (as well as certain

built-in

losses) and tax credit carryforwards, respectively (Tax Attributes), against future U.S. taxable income, if the corporation experiences an “ownership change.” In general terms, an ownership change may result from transactions increasing the ownership of certain stockholders in the stock of a corporation by more than 50 percentage points over a three-year period. The company regularly monitors ownership changes (as calculated for purposes of Section 382). The company has determined that, for purposes of the rules of Section 382 described above, an ownership change occurred in February 2011. Any future transaction or transactions and the timing of such transaction or transactions could trigger additional ownership changes under Section 382.

As a result of the February 2011 ownership change, utilization for certain of the company’s Tax Attributes, U.S. net operating losses and tax credits, is subject to an overall annual limitation of $70.6 million. The cumulative limitation as of December 31, 2021 is approximately $462.4 million. This limitation will be applied to any net operating losses and then to any other Tax Attributes. Any unused limitation may be carried over to later years. Based on presently available information and the existence of tax planning strategies, the company does not expect to incur a U.S. cash tax liability in the near term. The company maintains a full valuation allowance against the realization of all U.S. deferred tax assets as well as certain foreign deferred tax assets in excess of deferred tax liabilities.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Accounts receivable	12 Months Ended
Accounts receivable	Dec. 31, 2021
Receivables [Abstract]
Accounts receivable	Note 10 — Accounts receivable Accounts receivable consist principally of trade accounts receivable from customers and are generally unsecured and due within 30 to 90 days. Credit losses relating to these receivables consistently have been within management’s expectations. Expected credit losses are recorded as an allowance for doubtful accounts in the consolidated balance sheets. Estimates of expected credit losses are based primarily on the aging of the accounts receivable balances. The company records a specific reserve for individual accounts when it becomes aware of a customer’s inability to meet its financial obligations, such as in the case of bankruptcy filings or deterioration in the customer’s operating results or financial position. The collection policies and procedures of the company vary by credit class and prior payment history of customers. Revenue recognized in excess of billings on services contracts, or unbilled accounts receivable, was $73.1 million and $63.3 million at December 31, 2021 and 2020, respectively. The allowance for doubtful accounts, which is reported as a deduction from accounts receivable, was $8.0 million and $9.2 million at December 31, 2021 and 2020, respectively. The provision for doubtful accounts, which is reported in selling, general and administrative expenses in the consolidated statements of income (loss), was (income) expense of $(0.6) million, $(0.3) million and $(1.6) million, in 2021, 2020 and 2019, respectively. Additionally, long-term receivables were $49.1 million and $84.4 million at December 31, 2021 and 2020, respectively, and are reported in other long-term assets on the company’s consolidated balance sheets.

Revenue from Contract with Customer [Abstract]

Capitalized contract costs

Note 12 — Capitalized contract costs

The company’s incremental direct costs of obtaining a contract consist of sales commissions which are deferred and amortized ratably over the initial contract life. These costs are classified as current or noncurrent based on the timing of when the company expects to recognize the expense. The current and noncurrent portions of deferred commissions are included in prepaid expenses and other current assets and in other long-term assets, respectively, in the company’s consolidated balance sheets.

Deferred commissions were as follows:


As of December 31,	2021		2020
Deferred commissions	$	6.7	$	8.7

Amortization expense related to deferred commissions was as follows:


Year ended December 31,	2021		2020		2019
Deferred commissions—amortization expense (i)	$	2.9	$	3.2	$	3.1

(i)	Reported in selling, general and administrative expense in the company’s consolidated statements of income (loss)

Costs on outsourcing contracts are generally expensed as incurred. However, certain costs incurred upon initiation of an outsourcing contract (costs to fulfill a contract), principally initial customer setup, are capitalized and expensed over the initial contract life. These costs are included in outsourcing assets, net in the company’s consolidated balance sheets, and are amortized over the initial contract life and reported in cost of revenue.

Costs to fulfill a contract were as follows:


As of December 31,	2021		2020
Costs to fulfill a contract	$	56.2	$	74.4

Amortization expense related to costs to fulfill a contract was as follows:


Year ended December 31,	2021		2020		2019
Costs to fulfill a contract—amortization expense	$	27.9	$	27.5	$	24.2

The remaining balance of outsourcing assets, net is comprised of fixed assets and software used in connection with outsourcing contracts. These costs are capitalized and depreciated over the shorter of the initial contract life or in accordance with the company’s fixed asset policy.

Financial instruments and concentration of credit risks

Fair Value Disclosures [Abstract]

Financial instruments and concentration of credit risks

Note 13 — Financial instruments and concentration of credit risks

Due to its foreign operations, the company is exposed to the effects of foreign currency exchange rate fluctuations on the U.S. dollar, principally related to intercompany account balances. The company uses derivative financial instruments to reduce its exposure to market risks from changes in foreign currency exchange rates on such balances. The company enters into foreign exchange forward contracts, generally having maturities of three months or less, which have not been designated as hedging instruments. At December 31, 2021 and 2020, the notional amount of these contracts was $552.2 million and $588.5 million, respectively. The fair value of these forward contracts is based on quoted prices for similar but not identical financial instruments; as such, the inputs are considered Level 2 inputs.

The following table summarizes the fair value of the company’s foreign exchange forward contracts.


As of December 31,	2021		2020
Balance Sheet Location
Prepaid expenses and other current assets	$	3.6	$	1.4
Other accrued liabilities		2.1		1.0

Total fair value	$	1.5	$	0.4

The following table summarizes the location and amount of gains (losses) recognized on foreign exchange forward contracts.


Year Ended December 31,	2021			2020		2019
Statement of Income Location
Other (expense), net	$	(18.8	)	$	7.6	$	1.7

Financial instruments include temporary cash investments and customer accounts receivable. Temporary investments are placed with creditworthy financial institutions, primarily in money market funds, time deposits and certificate of deposits which may be withdrawn at any time at the discretion of the company without penalty. At December 31, 2021 and 2020, the company’s cash equivalents principally have maturities of less than one month or can be withdrawn at any time at the discretion of the company without penalty. Due to the short maturities of these instruments, they are carried on the consolidated balance sheets at cost plus accrued interest, which approximates fair value. Receivables are due from a large number of customers that are dispersed worldwide across many industries. At December 31, 2021 and 2020, the company had no significant concentrations of credit risk with any one customer.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

Long-lived assets to be sold are classified as

held-for-sale

in the period in which they meet all the criteria for the disposal of long-lived assets. The company measures assets

held-for-sale

at the lower of their carrying amount or fair value less cost to sell. Additionally, the company determined that such assets comprise operations and cash flows that can be clearly distinguished, operationally and for financial reporting purposes, from the rest of the company.

In September 2021, the company entered into a letter of intent (LOI) with a third party for the sale of certain facilities, land and equipment related to a data center facility located in Eagan, Minnesota. Upon the execution of the LOI, these assets were classified as

held-for-sale

in the company’s consolidated balance sheet and measured at the lower of their carrying amount or fair value less cost to sell.

Senior Secured Notes due 2027

On October 29, 2020, the company issued $485.0 million aggregate principal amount of its 6.875% Senior Secured Notes due 2027 (the 2027 Notes). The 2027 Notes pay interest semiannually on May 1 and November 1 and will mature on November 1, 2027, unless earlier repurchased or redeemed. The 2027 Notes are fully and unconditionally guaranteed on a senior secured basis by Unisys Holding Corporation, Unisys NPL, Inc., Unisys AP Investment Company I, CompuGain LLC and CompuGain Public Services, LLC, each of which is a U.S. corporation or limited liability company that is directly or indirectly owned by the company (the subsidiary guarantors).

The 2027 Notes and the related guarantees rank equally in right of payment with all of the existing and future senior debt of the company and its subsidiary guarantors and senior in right of payment to any future subordinated debt of the company and its subsidiary guarantors. The 2027 Notes and the related guarantees are structurally subordinated to all existing and future liabilities (including preferred stock, trade payables and pension liabilities) of the subsidiaries of the company that are not subsidiary guarantors. The 2027 Notes and the guarantees are secured by liens on substantially all assets of the company and the subsidiary guarantors, other than certain excluded assets (the collateral). The liens securing the 2027 Notes on certain ABL collateral are subordinated to the liens on ABL collateral in favor of the ABL secured parties and, in the future, the liens securing the 2027 Notes may be subordinated to liens on the collateral securing certain permitted first lien debt, subject to certain limitations and permitted liens.

Prior to November 1, 2023 the company may, at its option, redeem some or all of the 2027 Notes at any time, at a price equal to 100% of the principal amount of the 2027 Notes redeemed plus a “make-whole” premium, plus accrued and unpaid interest, if any. The company may also redeem, at its option, up to 40% of the 2027 Notes at any time prior to November 1, 2023, using the proceeds of certain equity offerings at a redemption price of 106.875% of the principal amount thereof, plus accrued and unpaid interest, if any. On or after November 1, 2023, the company may, on any one or more occasions, redeem all or a part of the 2027 Notes at specified redemption premiums, declining to par for any redemptions on or after November 1, 2025.

The indenture contains covenants that limit the ability of the company and its restricted subsidiaries to, among other things: (i) incur additional indebtedness and guarantee indebtedness; (ii) pay dividends or make other distributions or repurchase or redeem its capital stock; (iii) prepay, redeem or repurchase certain debt; (iv) make certain prepayments in respect of pension obligations; (v) issue certain preferred stock or similar equity securities; (vi) make loans and investments (including investments by the company and subsidiary guarantors in subsidiaries that are not guarantors); (vii) sell assets; (viii) create or incur liens; (ix) enter into transactions with affiliates; (x) enter into agreements restricting its subsidiaries’ ability to pay dividends; and (xi) consolidate, merge or sell all or substantially all of its assets. These covenants are subject to several important limitations and exceptions.

If the company experiences certain kinds of changes of control (as defined in the indenture), it will be required to offer to repurchase the 2027 Notes at 101% of the principal amount of the 2027 Notes, plus accrued and unpaid interest as of the repurchase date, if any. In addition, if the company sells assets under certain circumstances it must apply the proceeds towards an offer to repurchase the 2027 Notes at a price equal to par plus accrued and unpaid interest, if any.

The indenture also provides for events of default, which, if any of them occur, would permit or require the principal, premium, if any, interest and any other monetary obligations on all the then outstanding 2027 Notes to be due and payable immediately.

Interest expense related to the 2027 Notes is comprised of the following:

Senior Secured Notes due 2022

On April 15, 2020, the company redeemed all $440.0 million in aggregate principal amount of its outstanding 10.750% Senior Secured Notes due 2022 (the 2022 Notes) for a redemption price equal to 105.375% of the aggregate principal amount of the 2022 Notes redeemed plus accrued but unpaid interest to, but not including, the redemption date. The redemption price paid was $487.3 million and is made up of the following: $440.0 million of principal amount due, $23.65 million of call premium and $23.65 million of accrued interest through April 14, 2020. In 2020, the company recorded a loss on debt extinguishment in other expense, net of $28.5 million consisting of the premium of $23.65 million and write off of $4.8 million of unamortized discount and fees related to the issuance of the 2022 Notes.

Interest expense related to the 2022 Notes is comprised of the following:

Convertible Senior Notes Due 2021

In 2016, the company issued $213.5 million aggregate principal amount of Convertible Senior Notes due 2021 (the 2021 Notes). Following the completion of the separate, privately negotiated exchange agreements in 2019, $84.2 million aggregate principal amount of 2021 Notes remained outstanding.

On March 3, 2021, the company completed the conversion of $84.2 million aggregate principal amount of the 2021 Notes that remained outstanding for a combination of cash and shares of the company’s common stock. As a result of the conversion of the outstanding 2021 Notes, the company delivered to the holders of such notes (i) aggregate cash payments totaling approximately $86.5 million, which included an aggregate cash payment for outstanding principal of approximately $84.2 million, an aggregate cash payment for accrued interest of approximately $2.3 million and a nominal cash payment in lieu of fractional shares, and (ii) 4,537,123 shares of the company’s common stock in the aggregate. The issuance of the common stock was made in exchange for the 2021 Notes pursuant to an exemption from the registration requirements provided by Section 3(a)(9) of the Securities Act of 1933, as amended.

The company also received 1,251,460 shares of its common stock, held in treasury stock, from the settlement of the capped call transactions that the company had entered into with the initial purchasers and/or affiliates of the initial purchasers of the 2021 Notes in connection with the issuance of the 2021 Notes. As a result, the net number of outstanding shares of the company’s common stock following the conversion of the 2021 Notes increased by 3,285,663 shares.

Interest expense related to the 2021 Notes is comprised of the following:

Other Debt

In 2019, the company entered into a $27.7 million Installment Payment Agreement (IPA) maturing on December 20, 2023 with a syndicate of financial institutions to finance the acquisition of certain software licenses necessary for the provision of services to a client. Interest accrues at an annual rate of 7.0% and the company is required to make monthly principal and interest payments on each agreement in arrears. At December 31, 2021 and 2020, $5.5 million and $6.5 million, was reported in current maturities of long-term debt, respectively.

In 2019, the company entered into a vendor agreement in the amount of $19.3 million to finance the acquisition of certain software licenses used to provide services to our clients and for its own internal use. Interest accrues at an annual rate of 5.47% and the company is required to make annual principal and interest payments in advance with the last payment due on March 1, 2024. At December 31, 2021 and 2020, $3.8 million and $3.6 million was reported in current maturities of long-term debt, respectively.

Asset Based Lending (ABL) Credit Facility

Contemporaneously with the issuance of the 2027 Notes, the company and the subsidiary guarantors entered into an amendment and restatement of the company’s secured revolving credit facility (the Amended and Restated ABL Credit Facility) that provides for revolving loans and letters of credit up to an aggregate amount of $145.0 million (with a limit on letters of credit of $40.0 million), with an accordion feature provision allowing for the aggregate amount available under the credit facility to be increased up to $175.0 million upon the satisfaction of certain conditions specified in the Amended and Restated ABL Credit Facility. The amendment and restatement extended the maturity from October 2022 to October 29, 2025 and modified certain other terms and covenants. Availability under the credit facility is subject to a borrowing base calculated by reference to the company’s receivables. At December 31, 2021, the company had no borrowings and $5.7 million of letters of credit outstanding, and availability under the facility was $80.4 million net of letters of credit issued.

The Amended and Restated ABL Credit Facility is subject to a springing maturity, under which the Amended and Restated ABL Credit Facility will immediately mature 91 days prior to any date on which contributions to pension funds in the United States in an amount in excess of $100.0 million are required to be paid unless the company is able to meet certain conditions, including that the company has the liquidity (as defined in the Amended and Restarted ABL Credit Facility) to cash settle the amount of such pension payments, no default or event of default has occurred under the Amended and Restated ABL Credit Facility, the company’s liquidity is above $130.0 million and the company is in compliance with the then applicable fixed charge coverage ratio on a pro forma basis.

The Amended and Restated ABL Credit Facility is guaranteed by the subsidiary guarantors and any future material domestic subsidiaries. The facility is secured by the assets of the company and the subsidiary guarantors, other than certain excluded assets, under a security agreement entered into by the company and the subsidiary guarantors in favor of JPMorgan Chase Bank, N.A., as agent for the lenders under the credit facility.

The company is required to maintain a minimum fixed charge coverage ratio if the availability under the Amended and Restated ABL Credit Facility falls below the greater of 10% of the lenders’ commitments under the facility and $14.5 million.

The Amended and Restated ABL Credit Facility contains customary representations and warranties, including, but not limited to, that there has been no material adverse change in the company’s business, properties, operations or financial condition. The Amended and Restated ABL Credit Facility includes restrictions on the ability of the company and its subsidiaries to, among other things, incur other debt or liens, dispose of assets and make acquisitions, loans and investments, repurchase its equity, and prepay other debt. These restrictions are subject to several important limitations and exceptions. Events of default include

non-payment,

failure to comply with covenants, materially incorrect representations and warranties, change of control and default under other debt aggregating at least $50.0 million, subject to relevant cure periods, as applicable.

Note 18 — Employee plans

Stock plans

Under stockholder approved stock-based plans, stock options, stock appreciation rights, restricted stock and restricted stock units may be granted to officers, directors and other key employees. At December 31, 2021, 6.8 million shares of unissued common stock of the company were available for granting under these plans.

As of December 31, 2021, the company has granted

non-qualified

stock options, restricted stock and restricted stock units under these plans. The company recognizes compensation cost, net of a forfeiture rate, in selling, general and administrative expenses, and recognizes the compensation cost for only those awards expected to vest. The company estimates the forfeiture rate based on its historical experience and its expectations about future forfeitures.

During the years ended December 31, 2021, 2020 and 2019, the company recorded $18.8 million, $14.5 million and $13.2 million of restricted stock and restricted stock unit compensation expense, respectively.

Restricted stock and restricted stock unit awards may contain time-based units, performance-based units, total shareholder return market-based units, or a combination of these units. Each performance-based and market-based unit will vest into zero to two shares depending on the degree to which the performance or market conditions are met. Compensation expense for performance-based awards is recognized as expense ratably for each installment from the date of grant until the date the restrictions lapse and is based on the fair market value at the date of grant and the probability of achievement of the specific performance-related goals. Compensation expense for market-based awards is recognized as expense ratably over the measurement period, regardless of the actual level of achievement, provided the service requirement is met. Restricted stock unit grants for the company’s directors vest upon award and compensation expense for such awards is recognized upon grant.

A summary of restricted stock and restricted stock unit (RSU) activity for the year ended December 31, 2021 follows (shares in thousands):


	Restricted Stock and RSU’s			Weighted- Average Grant-Date Fair Value
Outstanding at December 31, 2020		1,726		$	17.87
Granted		1,590			25.38
Vested		(923	)		16.60
Forfeited and expired		(269	)		19.02

Outstanding at December 31, 2021		2,124			22.73

The aggregate weighted-average grant-date fair value of restricted stock and restricted stock units granted during the years ended December 31, 2021, 2020 and 2019 was $37.5 million, $17.4 million and $16.9 million, respectively. The fair value of restricted stock and restricted stock units with time and performance conditions is determined based on the trading price of the company’s common shares on the date of grant. The fair value of awards with market conditions is estimated using a Monte Carlo simulation with the following weighted-average assumptions.


Year ended December 31,	2021			2020
Weighted-average fair value of grant	$	40.02		$	28.33
Risk-free interest rate (i)		0.27	%		1.35	%

(i)	Represents the continuously compounded semi-annual zero-coupon U.S. treasury rate commensurate with the remaining performance period

(ii)	Based on historical volatility for the company that is commensurate with the length of the performance period

(iii)

Represents the remaining life of the longest performance period

As of December 31, 2021, there was $25.0 million of total unrecognized compensation cost related to outstanding restricted stock and restricted stock units granted under the company’s plans. That cost is expected to be recognized over a weighted-average period of 2.3 years. The aggregate weighted-average grant-date fair value of restricted stock and restricted stock units vested during the years ended December 31, 2021, 2020 and 2019 was $15.3 million, $13.0 million and $14.9 million, respectively.

Common stock issued upon lapse of restrictions on restricted stock and restricted stock units are newly issued shares. In light of its tax position, the company is currently not recognizing any tax benefits from the issuance of stock upon lapse of restrictions on restricted stock and restricted stock units.

Defined contribution and compensation plans

U.S. employees are eligible to participate in an employee savings plan. Under this plan, employees may contribute a percentage of their pay for investment in various investment alternatives. The company matches 50 percent of the first 6 percent of eligible pay contributed by participants to the plan on a

before-tax

basis (subject to IRS limits). The company funds the match with cash. The charge to income related to the company match for the years ended December 31, 2021, 2020 and 2019, was $7.5 million, $8.8 million and $8.2 million, respectively.

The company has defined contribution plans in certain locations outside the United States. The charge to income related to these plans was $16.4 million, $16.2 million and $19.3 million, for the years ended December 31, 2021, 2020 and 2019, respectively.

The company has

non-qualified

compensation plans, which allow certain highly compensated employees and directors to defer the receipt of a portion of their salary, bonus and fees. Participants can earn a return on their deferred balance that is based on hypothetical investments in various investment vehicles. Changes in the market value of these investments are reflected as an adjustment to the liability with an offset to expense. As of December 31, 2021 and 2020, the liability to the participants of these plans was $10.6 million and $12.7 million, respectively. These amounts reflect the accumulated participant deferrals and earnings thereon as of that date. The company makes no contributions to the deferred compensation plans and remains contingently liable to the participants.

Retirement benefits

For the company’s more significant defined benefit pension plans, including the U.S. and U.K., accrual of future benefits under the plans has ceased. Management develops the actuarial assumptions used by its U.S. and international defined benefit pension plan obligations based upon the circumstances of each particular plan. The determination of the defined benefit pension plan obligations requires the use of estimates.

In January of 2021, the company purchased a group annuity contract for $279 million to transfer projected benefit obligations related to approximately 11,600 retirees of the company’s U.S. defined benefit pension plans. This action resulted in a

pre-tax

settlement loss of $158.0 million.

Effective May 1, 2021, the company’s primary pension plan related to its Dutch subsidiary was transferred to a multi-client circle within a multi-employer fund. This resulted in removing all of the plan’s projected benefit obligations, valued at approximately $553 million, from the company’s balance sheet. This action resulted in a

pre-tax

settlement loss of $182.5 million.

In the second quarter of 2021, the company’s Swiss subsidiary transferred its defined benefit pension plan to a multiple-employer collective foundation. This resulted in removing the projected benefit obligations related to retirees under the Swiss plan, valued at approximately $100 million, from the company’s balance sheet. The transfer required a

one-time

additional contribution of approximately $10 million to the Swiss plan in 2021. This action resulted in a

pre-tax

settlement loss of $28.8 million.

On October 14, 2021, the company purchased a group annuity contract for approximately $235 million to transfer projected benefit obligations related to approximately 6,900 retirees of the company’s U.S. defined benefit pension plans. This action resulted in a

pre-tax

settlement loss of $130.1 million.

The American Rescue Plan Act, which was signed into law in the U.S. on March 11, 2021, includes a provision for pension relief that extends the amortization period for required contributions from 7 to 15 years and provides for the stabilization of interest rates used to calculate future required contributions. As a result, the company was not required to make cash contributions to its U.S. qualified defined benefit pension plans in 2021.

In December 2020, the company completed a

lump-sum

cash-out

offer for eligible former associates who had deferred vested benefit under the company’s U.S. defined benefit pension plans to receive the value of their entire pension benefit in a

lump-sum

payment. As a result, the pension plan trust made lump sum payments to approximately 3,500 former associates of $276.0 million and the company recorded a

non-cash

pre-tax

settlement charge of $142.1 million.

Management’s significant assumption used in the determination of the defined benefit pension plan obligations, and settlement losses with respect to the U.S. pension plans, is the discount rate. Weighted-average assumptions used to determine net periodic pension cost were as follows:


	U.S. Plans									International Plans
Year ended December 31,	2021			2020			2019			2021			2020			2019
Discount rate		2.85	%		3.53	%		4.50	%		1.23	%		1.82	%		2.55	%
Expected long-term rate of return on assets		6.07	%		6.50	%		6.80	%		3.30	%		3.50	%		4.18	%

Weighted-average assumptions used to determine benefit obligations at December 31 were as follows:

Discount rate		3.18	%		2.85	%		3.53	%		1.73	%		1.23	%		1.82	%

The company’s investment policy targets and ranges for each asset category are as follows:


	U.S.						International
Asset Category	Target			Range			Target			Range
Equity securities		52	%		47-57	%		18	%		15-20	%
Debt securities		34	%		29-39	%		62	%		57-66	%
Cash		0	%		0-5	%		0	%		0-5	%
Other		14	%		9-19	%		20	%		17-24	%

The company periodically reviews its asset allocation, taking into consideration plan liabilities, local regulatory requirements, plan payment streams and then-current capital market assumptions. The actual asset allocation for each plan is monitored at least quarterly, relative to the established policy targets and ranges. If the actual asset allocation is close to or out of any of the ranges, a review is conducted. Rebalancing will occur toward the target allocation, with due consideration given to the liquidity of the investments and transaction costs.

The objectives of the company’s investment strategies are as follows: (a) to provide a total return that, over the long term, increases the ratio of plan assets to liabilities by maximizing investment return on assets, at a level of risk deemed appropriate, (b) to maximize return on assets by investing in equity securities in the U.S. and for international plans by investing in appropriate asset classes, subject to the constraints of each plan’s asset allocation targets, as discussed above, design and local regulations, (c) to diversify investments within asset classes to reduce the impact of losses in single investments, and (d) for the U.S. plans to invest in compliance with the Employee Retirement Income Security Act of 1974 (ERISA), as amended and any subsequent applicable regulations and laws, and for international plans to invest in a prudent manner in compliance with local applicable regulations and laws.

The company sets the expected long-term rate of return based on the expected long-term return of the various asset categories in which it invests. The company considered the current expectations for future returns and the actual historical returns of each asset class. Also, since the company’s investment policy is to actively manage certain asset classes where the potential exists to outperform the broader market, the expected returns for those asset classes were adjusted to reflect the expected additional returns.

In 2022, the company expects to make cash contributions of $40.2 million, primarily for international defined benefit pension plans.

As of December 31, 2021, the following benefit payments are expected to be paid from the defined benefit pension plans:


Year	U.S.		International
2022	$	308.6	$	87.9
2023		302.4		90.9

Year ended December 31,	2021			2020			2019
Discount rate		2.70	%		2.21	%		5.13	%

The company reviews its asset allocation periodically, taking into consideration plan liabilities, plan payment streams and then-current capital market assumptions. The company sets the long-term expected return on asset assumption, based principally on the long-term expected return on debt securities. These return assumptions are based on a combination of current market conditions, capital market expectations of third-party investment advisors and actual historical returns of the asset classes. In 2022, the company expects to contribute approximately $6 million to its postretirement benefit plans.

The following provides a description of the valuation methodologies and the levels of inputs used to measure fair value, and the general classification of investments in the company’s U.S. and international defined benefit pension plans, and the company’s other postretirement benefit plan.

Level 1 – These investments include cash, common stocks, real estate investment trusts, exchange traded funds, futures and options and U.S. government securities. These investments are valued using quoted prices in an active market. Payables, receivables and cumulative futures contracts variation margin received from brokers are also included as Level 1 investments and are valued at face value.

Level 2 – These investments include the following:

Pooled Funds – These investments are comprised of money market funds and fixed income securities. The money market funds are valued using the readily determinable fair value (RDFV) provided by trustees of the funds. The fixed income securities are valued based on quoted prices for identical or similar investments in markets that may not be active.

Commingled Funds – These investments are comprised of debt, equity and other securities and are valued using the RDFV provided by trustees of the funds. The fair value per share for these funds are published and are the basis for current transactions.

Other Fixed Income – These investments are comprised of corporate and government fixed income investments and asset and mortgage-backed securities for which there are quoted prices for identical or similar investments in markets that may not be active.

Derivatives – These investments include forward exchange contracts and options, which are traded on an active market, but not on an exchange; therefore, the inputs may not be readily observable. These investments also include fixed income futures and other derivative instruments.

Level 3 – These investments include the following:

Insurance Contracts – These investments are insurance contracts which are carried at book value, are not publicly traded and are reported at a fair value determined by the insurance provider.

Certain investments are valued using net asset value (NAV) as a practical expedient. These investments may not be redeemable on a daily basis and may have redemption notice periods of up to 120 days. These investments include the following:

Commingled Funds – These investments are comprised of debt, equity and other securities.

Private Real Estate and Private Equity – These investments represent interests in limited partnerships which invest in privately-held companies or privately-held real estate or other real assets. Net asset values are developed and reported by the general partners that manage the partnerships. These valuations are based on property appraisals, utilization of market transactions that provide valuation information for comparable companies, discounted cash flows, and other methods. These valuations are reported quarterly and adjusted as necessary at year end based on cash flows within the most recent period.

The following table sets forth by level, within the fair value hierarchy, the plans’ assets (liabilities) at fair value at December 31, 2021.

Litigation and contingencies	12 Months Ended
Litigation and contingencies	Dec. 31, 2021
Commitments and Contingencies Disclosure [Abstract]
Litigation and contingencies	Note 19 — Litigation and contingencies There are various lawsuits, claims, investigations and proceedings that have been brought or asserted against the company, which arise in the ordinary course of business, including actions with respect to commercial and government contracts, labor and employment, employee benefits, environmental matters, intellectual property and non-income tax matters. The company records a provision for these matters when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Any provisions are reviewed at least quarterly and are adjusted to reflect the impact and status of settlements, rulings, advice of counsel and other information and events pertinent to a particular matter. The company believes that it has valid defenses with respect to legal matters pending against it. Based on its experience, the company also believes that the damage amounts claimed in the lawsuits disclosed below are not a meaningful indicator of the company’s potential liability. Litigation is inherently unpredictable, however, and it is possible that the company’s results of operations or cash flow could be materially affected in any particular period by the resolution of one or more of the legal matters pending against it. The company’s Brazilian operations, along with those of many other companies doing business in Brazil, are involved in various litigation matters, including numerous governmental assessments related to indirect and other taxes, as well as disputes associated with former employees and contract labor. The tax-related matters pertain to value-added taxes, customs, duties, sales and other non-income-related tax exposures. The labor-related matters include claims related to compensation. The company believes that appropriate accruals have been established for such matters based on information currently available. At December 31, 2021, excluding those matters that have been assessed by management as being remote as to the likelihood of ultimately resulting in a loss, the amount related to unreserved tax-related matters, inclusive of any related interest, is estimated to be up to approximately $75 million. With respect to the specific legal proceedings and claims described above, except as otherwise noted, either (i) the amount or range of possible losses in excess of amounts accrued, if any, is not reasonably estimable or (ii) the company believes that the amount or range of possible losses in excess of amounts accrued that are estimable would not be material. Litigation is inherently unpredictable and unfavorable resolutions could occur. Accordingly, it is possible that an adverse outcome from such matters could exceed the amounts accrued in an amount that could be material to the company’s financial condition, results of operations and cash flows in any particular reporting period. Notwithstanding that the ultimate results of the lawsuits, claims, investigations and proceedings that have been brought or asserted against the company are not currently determinable, the company believes that at December 31, 2021, it has adequate provisions for any such matters.

Segment information

12 Months Ended

Dec. 31, 2021

Segment Reporting [Abstract]

Segment information

Note 21 — Segment information

The company’s reportable segments are as follows:

•

Digital Workplace Solutions (DWS), which provides solutions that transform digital workplaces securely and create exceptional

end-user

experiences;

•

Cloud and Infrastructure Solutions (C&I), which provides solutions that drive modern IT service platforms, cloud applications development, intelligent services, and cybersecurity services; and

•

Enterprise Computing Solutions (ECS), which provides solutions that harness secure, continuous high-intensity computing and enable digital services through software-defined operating environments.

The accounting policies of each segment are the same as those followed by the company as a whole. Intersegment sales and transfers are priced as if the sales or transfers were to third parties. Accordingly, the ECS segment records intersegment revenue and manufacturing profit on hardware and software shipments to customers under contracts of other segments. These segments, in turn, record customer revenue and marketing profits on such shipments of company hardware and software to customers. In the company’s consolidated statements of income (loss), the manufacturing costs of products sourced from the ECS segment and sold to other segments’ customers are reported in cost of revenue for these other segments. Also included in the ECS segment’s sales and gross profit are sales of hardware and software sold to other segments for internal use in their engagements. The amount of such profit included in gross profit of the ECS segment for the years ended December 31, 2021, 2020 and 2019 was $1.4 million, $7.8 million and $5.7 million, respectively. The sales and profit on these transactions is eliminated in Corporate.

The company evaluates segment performance based on gross profit exclusive of the service cost component of postretirement income or expense, restructuring charges, amortization of purchased intangibles and unusual and nonrecurring items, which are included in Corporate. In 2021, the company also changed its internal measurement of segment profitability. Prior period amounts have therefore been reclassified to be comparable to the current period’s presentation. No single customer accounts for more than 10% of revenue.

Corporate assets are principally cash and cash equivalents, prepaid postretirement assets and deferred income taxes. The expense or income related to corporate assets and centrally incurred costs are allocated to the business segments.

A summary of the company’s operations by reportable segment is presented below:

Revenue recognition

Revenue from software licenses is recognized at the inception of either the initial license term or the inception of an extension or renewal to the license term.

cost-to-cost

method, or when services have been performed, depending on the nature of the project. For contracts accounted for using the

cost-to-cost

time-and-materials

basis, as a fixed-price contract or as a fixed-price per measure of output contract.

Revenue from

time-and-material

contracts is recognized on an output basis as labor hours are delivered.

The company discloses disaggregation of its customer revenue by geographic areas by segment (see Note 21, “Segment information”).

The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled receivables, contract assets and deferred revenue (contract liabilities).

Shipping and handling

Costs related to shipping and handling are included in cost of revenue.

Advertising costs

All advertising costs are expensed as incurred.

Stock-based compensation plans

Income taxes

The company treats the global intangible

low-tax

income tax, or GILTI, as a period cost when included in U.S. taxable income, and the base erosion and anti-abuse tax, or BEAT, as a period cost when incurred.

Translation of foreign currency

The local currency is the functional currency for most of the company’s international subsidiaries, and as such, assets and liabilities are translated into U.S. dollars at

year-end

Recent accounting pronouncements and accounting changes

Effective January 1, 2020, the company adopted Accounting Standards Update (ASU)

No. 2019-12,

Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which removed certain exceptions 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 new standard was applied to the presentation of the company’s U.S. Federal business, which is reflected in discontinued operations.

In October 2021, the Financial Accounting Standards Board issued ASU

No. 2021-08,

Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. This guidance requires that an acquirer recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with ASC 606, Revenue from Contracts with Customers, as if it had originated the contracts. Deferred revenue acquired in a business combination is no longer required to be measured at its fair value, which had historically resulted in a deferred revenue impairment at the date of acquisition. The amendment is effective January 1, 2023 and early adoption is permitted. The company expects to adopt this new guidance effective January 1, 2022.
