| Accounting Policies [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Summary of significant accounting policies | 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 U.S. generally accepted accounting principles 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 accounts receivable, inventories, outsourcing assets, marketable software, goodwill and other long-lived assets, legal contingencies, indemnifications, assumptions used in the measurement of progress toward completion 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 significantly 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. Cash and Cash equivalents Cash and cash equivalents consist of cash on hand, short-term investments purchased with a maturity of three months or less and certificates of deposit which may be withdrawn at any time at the discretion of the company without penalty.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. Restricted cash primarily consists of cash the company is contractually obligated to maintain in accordance with the terms of its U.K. business process outsourcing joint venture agreement and other cash that is restricted from withdrawal. 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.
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. Advertising costs All advertising costs are expensed as incurred. The amount charged to expense during 2018, 2017 and 2016 was $2.8 million, $1.6 million and $2.7 million, respectively. Shipping and handling Costs related to shipping and handling are included in cost of revenue. Goodwill Goodwill arising from the acquisition of an entity represents the excess of the cost of acquisition over the fair value of the acquired identifiable assets, liabilities and contingent liabilities of the entity recognized at the date of acquisition. Goodwill is initially recognized as an asset and is subsequently measured at cost less any accumulated impairment losses. Goodwill is held in the currency of the acquired entity and revalued to the closing rate at each balance sheet date. The company tests goodwill for impairment annually in the fourth quarter using data as of September 30th 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 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 in the period the impairment is identified. The company estimates the fair value of each reporting unit using a combination of the income approach and 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 gave more weighting to the income approach. The higher weighting assigned to the income approach took 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. 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. 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. 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. 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 time and materials service contracts and outsourcing contracts is recognized as the services are provided using either an objective measure of output or on a straight-line basis over the term of the contract. The company also enters into multiple-element arrangements, which 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. To the extent that a performance obligation in a multiple-deliverable arrangement is subject to specific guidance, that performance obligation is accounted for in accordance with such specific guidance. An example of such an arrangement may include leased assets which are subject to specific leasing accounting guidance. In multiple-element arrangements, the company allocates the total transaction price to be earned under the arrangement among the various performance obligations in proportion to their standalone selling prices (relative standalone selling price basis). 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. Many of the company’s contracts have a single performance obligation as the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts and, therefore, not distinct. 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 Services segment, 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 Technology segment, substantially all of the company’s goods and services 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. At December 31, 2018, the company had approximately $1.2 billion of remaining performance obligations of which approximately 40% is estimated to be recognized as revenue by the end of 2019. The company does not disclose the value of unsatisfied performance obligations for (1) contracts with an original expected length of one year or less and (2) contracts for which the company recognizes revenue at the amount to which it has the right to invoice for services performed. The company discloses disaggregation of its customer revenue by geographic areas and by classes of similar products and services, by segment (see note 17). The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled receivables, contract assets and deferred revenue (contract liabilities). The disclosure of contract assets is a new requirement due to the adoption of Topic 606. At December 31, 2017, contract assets were included in accounts receivable, net on the company’s consolidated balance sheet. At December 31, 2018, $22.2 million of long-term contract assets were included in other long-term assets on the company’s consolidated balance sheet. At December 31, 2018, deposit liabilities of $21.2 million were principally included in current deferred revenue. These deposit liabilities represent upfront consideration received from customers for services such as post-contract support and maintenance that allow the customer to terminate the contract at any time for convenience. Significant changes during 2018 in the above contract asset and liability balances were as follows: revenue of $307.1 million was recognized that was included in deferred revenue at December 31, 2017. 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. At December 31, 2018 and December 31, 2017, the company had $12.1 million and $11.0 million, respectively, of deferred commissions. For the year ended December 31, 2018, $6.9 million of amortization expense related to deferred commissions was recorded in selling, general and administrative expense in the company’s consolidated statement of income. Costs to fulfill a contract, which are incurred upon initiation of certain services contracts and are related to initial customer setup, are included in outsourcing assets, net in the company’s consolidated balance sheet. The amount of such cost at December 31, 2018 and December 31, 2017 was $79.5 million and $76.0 million, respectively. These costs are amortized over the initial contract life and reported in Services cost of sales. During 2018, $21.7 million was amortized. Recoverability of these costs are 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 cash flows could differ from these estimates. 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. 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. The company treats the global intangible low-taxed 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. 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, which is generally 3 years following product release. The company continually reassesses the estimated revenue-producing lives of the products and will revise the lives as necessary. The company performs quarterly reviews to ensure that unamortized costs remain recoverable from future revenue. 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. Outsourcing assets Costs on 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 outsourcing assets is subject to various business risks. Quarterly, the company compares the carrying value of the outsourcing assets with the undiscounted future cash flows expected to be generated by the outsourcing assets to determine if there is impairment. If impaired, the outsourcing 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. 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 on intercompany balances are reported in other income (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 translation are included in other income (expense), net. 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 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 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 company estimates the fair value of stock options using a Black-Scholes valuation model. The expense is recorded in selling, general and administrative expenses. 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. 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. 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. 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 long-term debt (see note 12), derivatives (see note 9) and to its postretirement plan assets (see note 14). 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. |

| Recent accounting pronouncements and accounting changes | Recent accounting pronouncements and accounting changes Accounting Pronouncements Adopted Effective January 1, 2018, the company adopted ASU No. 2017-07 Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost issued by the Financial Accounting Standards Board (“FASB”) which requires employers to present the service cost component of net periodic benefit cost in the same income statement line item(s) as other employee compensation costs arising from services rendered during the period. The other components of net periodic benefit cost are presented separately from the line items that include service cost and outside the subtotal of operating income. ASU No. 2017-07 allows a practical expedient that permits an entity to use amounts disclosed in its pension and other postretirement benefit plan footnote for the prior comparative periods as the estimation basis for applying the retrospective presentation requirements. The new guidance has been applied on a retrospective basis, using the practical expedient, whereby prior-period financial statements have been adjusted to reflect the adoption of the new guidance, as required by the FASB. For the years ended December 31, 2017 and 2016, $92.5 million and $81.6 million, respectively, of net periodic benefit cost other than service cost, was reclassified from cost of revenue, selling, general and administrative expenses and research and development expenses to other income (expense), net in the company’s consolidated results of operations (see note 14). Effective January 1, 2018, the company adopted ASU No. 2014-09 Revenue from Contracts with Customers (Topic 606) issued by the FASB which establishes principles that an entity shall apply to report useful information to users of financial statements about the nature, amount, timing and uncertainty of revenue and cash flows from a contract with a customer. Topic 606 allows for either “full retrospective” adoption, meaning the standard is applied to all periods presented, or “modified retrospective” adoption, meaning the standard is applied only to the most current period presented in the financial statements. Topic 606 requires the company to recognize revenue for certain transactions, including extended payment term software licenses and short-term software licenses, sooner than the prior rules would allow and requires the company to recognize software license extensions and renewals (the most significant impact upon adoption), later than the prior rules would allow. Topic 606 also requires significantly expanded disclosure requirements. The company has adopted the standard using the modified retrospective method and applied the standard to all contracts that were not completed as of January 1, 2018. The cumulative effect of the adoption was recognized as an increase in the company’s accumulated deficit of $21.4 million on January 1, 2018. The following table summarizes the effects of adopting ASU No. 2014-09 on the company’s consolidated financial statements as of and for the year ended December 31, 2018.
Included in the Technology revenue adjustments for the year ended December 31, 2018 in the above table is $53.0 million of revenue from software license extensions and renewals which were contracted for in the fourth quarter of 2017 and properly recorded as revenue at that time under the revenue recognition rules then in effect (Topic 605). Upon adoption of the new revenue recognition rules (Topic 606) on January 1, 2018, and since the company adopted Topic 606 under the modified retrospective method whereby prior periods were not restated, the company was required to include this $53.0 million in the cumulative effect adjustment to retained earnings on January 1, 2018. Topic 606 requires revenue related to software license renewals or extensions to be recorded when the new license term begins, which in the case of the $53.0 million is January 1, 2018. The company has excluded revenue and related profit for these software licenses to reflect the balances without the adoption of Topic 606 in the above table. This is a one-time adjustment and it will not reoccur in future periods. There are additional adjustments being made in the above table, but they do not represent previously recorded revenue. Those additional adjustments represent other differences between Topic 605 and Topic 606, principally extended payment term software licenses and short-term software licenses both of which are recorded at the inception of the license term under Topic 606, but were required to be recognized ratably over the software license term under Topic 605. An additional adjustment is that under Topic 605, a company was not able to recognize software license revenue until the last software license is delivered due to the lack of vendor specific objective evidence, whereas under Topic 606, a company is required to use the standalone selling price for all performance obligations. This resulted in software license revenue being recognized sooner under Topic 606 compared with Topic 605. In 2018, the company adopted ASU No. 2017-05 Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20) issued by the FASB which clarifies the scope and application of ASC 610-20 on the sale or transfer of nonfinancial assets and in substance nonfinancial assets to noncustomers, including partial sales. The company adopted the standard using the modified retrospective method. The cumulative effect of the adoption was recognized as a decrease in the company’s accumulated deficit of $6.3 million. Effective July 1, 2018, the company adopted ASU No. 2018-02 Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income by applying the changes in the period of adoption. The new guidance permits companies to reclassify stranded tax effects in accumulated other comprehensive income (“AOCI”) caused by the U.S. Tax Cuts and Jobs Act of 2017 (“TCJA”) to retained earnings. Upon enactment of the TCJA, the U.S. corporate tax rate was reduced from 35% to 21% and the Company's U.S. deferred tax balances and related valuation allowances were remeasured to the lower enacted U.S. corporate tax rate. In accordance with its accounting policy, the company releases the income tax effects of deferred tax balances that have a valuation allowance from AOCI once the reason the tax effects were established cease to exist (e.g. postretirement plan is liquidated). The new guidance allows for the reclassification of stranded tax effects as a result of the change in tax rates from the TCJA to be recorded upon adoption of the guidance rather than at cessation date. On July 1, 2018, $208.7 million related to postretirement plans was reclassified from AOCI to retained earnings. In September 2018, the company adopted SEC Release No. 33-10532, Disclosure Update and Simplification which amends certain disclosure requirements that were redundant, duplicative, overlapping, outdated or superseded. In addition, the rule expands the disclosure requirements on changes in stockholders’ equity for interim periods. Under this rule, a reconciliation of changes in stockholders' equity is required for each period for which an income statement is presented. The company applied the new disclosure requirements retrospectively to all periods presented. There was no overall impact on the company’s consolidated financial statements. Effective for the annual reporting period ended December 31, 2018, the company adopted 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 which adds, removes and clarifies disclosure requirements related to defined benefit pension and other postretirement plans. The company applied the changes on a retrospective basis for all periods presented. There was no overall impact on the company’s consolidated financial statements. Accounting Pronouncements Not Yet Adopted In August 2018, the FASB issued ASU No. 2018-15, Intangibles - Goodwill and Other - Internal - Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract which clarifies the accounting for implementation costs incurred in a cloud computing arrangement that is a service contract. This update is effective for fiscal years ending after December 15, 2019, with earlier adoption permitted. The new guidance can be applied retrospectively or prospectively to all implementation costs incurred after the date of adoption. The company is currently assessing when it will choose to adopt, and is currently evaluating the impact of the adoption on its consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13 Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments which introduces a new model for recognizing credit losses on financial instruments based on an estimate of current expected losses. This includes trade and other receivables, loans and other financial instruments. This update is effective for annual periods beginning after December 15, 2019, with earlier adoption permitted. The company is currently assessing when it will choose to adopt, and is currently evaluating the impact of the adoption on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02 Leases (Topic 842), which is intended to improve financial reporting about leasing transactions. The ASU requires organizations that lease assets, referred to as lessees, to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. The standard also requires disclosures to help investors and other financial statement users better understand the amount, timing and uncertainty of cash flows arising from leases. In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842), Targeted Improvements, which provides an alternative transition method permitting the recognition of a cumulative-effect adjustment to retained earnings on the date of adoption rather than restating comparative periods in transition as originally prescribed by Topic 842. The standard is effective for annual reporting periods beginning after December 15, 2018, which for the company is January 1, 2019. The company will adopt the new guidance utilizing the alternative transition method. The company reviewed lease contracts, implemented new lease accounting software, established new processes and internal controls and evaluated the impact of certain accounting policy elections. The adoption is expected to have a material impact on the consolidated financial position, and is not expected to have a material impact on the consolidated results of operations and cash flows. |

| Foreign currency | Foreign currency Effective July 1, 2018, the company’s Argentinian subsidiary began to apply highly inflationary accounting due to cumulative inflation of approximately 100 percent or more over the last 3-year period. 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 translation are included in other income (expense), net. The impact of applying highly inflationary accounting in the third quarter of 2018 was immaterial. At December 31, 2018, the company’s operations in Argentina had net monetary assets denominated in local currency of approximately $5.1 million. During the years ended December 31, 2018, 2017 and 2016, the company recognized foreign exchange gains (losses) in “Other income (expense), net” in its consolidated statements of income of $(5.9) million, $(9.9) million and $2.3 million, respectively. The year ended December 31, 2017 also includes $11.8 million of net foreign currency losses related to exiting foreign countries in connection with the company’s restructuring plan. |

| Income taxes | Income taxes Following is the total income (loss) before income taxes and the provision for income taxes for the three years ended December 31, 2018.
Following is a reconciliation of the provision (benefit) for income taxes at the United States statutory tax rate to the provision for income taxes as reported:
The Tax Cuts & Jobs Act (“TCJA”) reduced the U.S. federal income tax rate from 35% to 21% effective January 1, 2018, with no net financial statement impact due to the valuation allowance recorded against all U.S. deferred tax assets. Included in 2017 was a benefit of $50.4 million principally related to the TCJA’s elimination of the corporate Alternative Minimum Tax (“AMT”) and refund of all remaining AMT credits. The 2018 and 2016 provisions for income taxes included $(2.2) million and $3.5 million due to reductions in the Netherlands and U.K. income tax rates, respectively. The Netherlands rate reduction was enacted in the fourth quarter of 2018 and reduced the rate from 25% to 20.5% effective January 1, 2021. The U.K. rate reduction was enacted in the third quarter of 2016 and reduced the rate from 18% to 17% effective April 1, 2020. The tax effects of temporary differences and carryforwards that give rise to significant portions of deferred tax assets and liabilities at December 31, 2018 and 2017 were as follows:
2017 includes a remeasurement of U.S. deferred tax balances as the TCJA reduced the U.S. federal income tax rate from 35% to 21% effective January 1, 2018, with no net financial statement impact due to the valuation allowance recorded against all U.S. deferred tax assets. At December 31, 2018, the company has tax effected tax loss carryforwards as follows:
These carryforwards will expire as follows:
The company also has available tax credit carryforwards, which will expire as follows:
Failure to achieve forecasted taxable income might affect the ultimate realization of the company’s net deferred tax assets. Factors that may affect the company’s ability to achieve sufficient forecasted taxable income include, but are not limited to, the following: increased competition, a decline in sales or margins, loss of market share, the impact of the economic environment, delays in product availability and technological obsolescence. Under U.S. tax law effective through December 31, 2017, undistributed earnings of foreign subsidiaries were generally taxable upon repatriation to the U.S shareholder. Under the TCJA, effective January 1, 2018, distributions from foreign subsidiaries to U.S. shareholders are generally exempt from taxation. With this change in U.S. taxation of earnings of foreign subsidiaries under the TCJA, future distributions of earnings from foreign subsidiaries will generally be exempt from U.S. 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, 2018 approximated $25.3 million. As of January 1, 2018 the U.S. taxable income will include GILTI, which essentially includes net foreign subsidiaries’ earnings above a routine 10% return on their aggregate specified tangible assets. At December 31, 2017, the company made an accounting policy election to treat the GILTI as a period cost when included in U.S. taxable income. Cash paid for income taxes, net of refunds, for the three years ended December 31, 2018, was as follows:
A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:
The company recognizes penalties and interest accrued related to income tax liabilities in the provision for income taxes in its consolidated statements of income. At December 31, 2018 and 2017, the company had an accrual of $2.6 million and $2.3 million, respectively, for the payment of penalties and interest. At December 31, 2018, 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 significantly change; 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 2013 are closed for Brazil, and the audit periods through 2014 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, 2018 is approximately $454.9 million. This limitation will be applied first to any recognized built in losses, then 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. |

| Receivables [Abstract] | |||||||||||||||||||||||||||||||||||||||||
| Accounts receivable | 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 $94.4 million and $109.4 million at December 31, 2018 and 2017, respectively. As of December 31, 2018, receivables under sales-type leases before the allowance for unearned income were collectible as follows:
Unearned income, which is deducted from accounts receivable, was $8.4 million and $12.5 million at December 31, 2018 and 2017, respectively. The allowance for doubtful accounts, which is reported as a deduction from accounts receivable, was $13.7 million and $22.0 million at December 31, 2018 and 2017, respectively. The provision for doubtful accounts, which is reported in selling, general and administrative expenses in the consolidated statements of income, was (income) expense of $(5.1) million, $3.1 million and $2.2 million, in 2018, 2017 and 2016, respectively. |

| Fair Value Disclosures [Abstract] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Financial instruments and concentration of credit risks | 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, 2018 and 2017, the notional amount of these contracts was $384.7 million and $514.0 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, 2018 and 2017.
The following table summarizes the location and amount of gains and losses recognized on foreign exchange forward contracts for the three years ended December 31, 2018.
Financial instruments also 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, 2018 and 2017, 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 market value. Receivables are due from a large number of customers that are dispersed worldwide across many industries. At December 31, 2018 and 2017, the company had no significant concentrations of credit risk with any one customer. At December 31, 2018 and 2017, the company had $85.8 million and $75.8 million, respectively, of receivables due from various U.S. federal governmental agencies. At December 31, 2018 and 2017, the carrying amount of cash and cash equivalents approximated fair value. |

Maturities of long-term debt, including capital leases, in each of the next five years and thereafter are as follows:
Cash paid for interest and capitalized interest expense during the three years ended December 31, 2018 was as follows:
Senior Secured Notes In 2017, the company issued $440.0 million aggregate principal amount of 10.75% Senior Secured Notes due 2022 (the “2022 Notes”). The 2022 Notes are initially fully and unconditionally guaranteed on a senior secured basis by Unisys Holding Corporation, Unisys AP Investment Company I and Unisys NPL, Inc. (together with the Company, the “Grantors”). In the future, the 2022 Notes will be guaranteed by each material domestic subsidiary and each restricted subsidiary that guarantees the secured revolving credit facility and other indebtedness of the company or another subsidiary guarantor. The 2022 Notes and the guarantees will rank equally in right of payment with all of the existing and future senior debt of the company and the subsidiary guarantors. The 2022 Notes and the guarantees will be structurally subordinated to all existing and future liabilities (including preferred stock, trade payables and pension liabilities) of the company’s subsidiaries that are not subsidiary guarantors. The 2022 Notes pay interest semiannually on April 15 and October 15 at an annual rate of 10.75%, and will mature on April 15, 2022, unless earlier repurchased or redeemed. The company may, at its option, redeem some or all of the 2022 Notes at any time on or after April 15, 2020 at a redemption price determined in accordance with the redemption schedule set forth in the indenture governing the Notes (the “indenture”), plus accrued and unpaid interest, if any. Prior to April 15, 2020, the company may, at its option, redeem some or all of the 2022 Notes at any time, at a price equal to 100% of the principal amount of the 2022 Notes redeemed plus a “make-whole” premium, plus accrued and unpaid interest, if any. The company may also redeem, at its option, up to 35% of the 2022 Notes at any time prior to April 15, 2020, using the proceeds of certain equity offerings at a redemption price of 110.75% of the principal amount thereof, plus accrued and unpaid interest, if any. In addition, the company may redeem all (but not less than all) of the 2022 Notes at any time that the Collateral Coverage Ratio is less than the Required Collateral Coverage Ratio (as such terms are described below and further defined in the indenture) at a price equal to 100% of the principal amount of the 2022 Notes plus accrued and unpaid interest, if any. 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. The indenture also includes a covenant requiring that the company maintain a Collateral Coverage Ratio of not less than 1.50:1.00 (the “Required Collateral Coverage Ratio”) as of any test date. The Collateral Coverage Ratio is based on the ratio of (A) Grantor unrestricted cash and cash equivalents plus 4.75 multiplied by of the greater of (x) Grantor EBITDA for the most recently ended four fiscal quarters and (y) (i) the average quarterly Grantor EBITDA for the most recently ended seven fiscal quarters, multiplied by (ii) four, to (B) secured indebtedness of the Grantors. The Collateral Coverage Ratio is tested quarterly. If the Collateral Coverage Ratio is less than the Required Collateral Coverage Ratio as of any test date, and the company has not redeemed the 2022 Notes within 90 days thereafter, this will be an event of default under the indenture. If the company experiences certain kinds of changes of control, it must offer to purchase the 2022 Notes at 101% of the principal amount of the 2022 Notes, plus accrued and unpaid interest, if any. In addition, if the company sells assets under certain circumstances it must apply the proceeds towards an offer to repurchase the 2022 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 occurs, would permit or require the principal, premium, if any, interest and any other monetary obligations on all the then outstanding 2022 Notes to be due and payable immediately. Interest expense related to the 2022 Notes is comprised of the following:
Convertible Senior Notes In 2016, the company issued $213.5 million aggregate principal amount of Convertible Senior Notes due 2021 (the “2021 Notes”). The 2021 Notes, which are senior unsecured obligations, bear interest at a coupon rate of 5.50% (or 9.5% effective interest rate) per year until maturity, payable semiannually in arrears on March 1 and September 1 of each year. The 2021 Notes are not redeemable prior to maturity and are convertible into shares of the company’s common stock. The conversion rate for the 2021 Notes is 102.4249 shares of the company’s common stock per $1,000 principal amount of the 2021 Notes (or a total amount of 21,867,716 shares), which is equivalent to an initial conversion price of approximately $9.76 per share of the company’s common stock. Upon any conversion, the company will settle its conversion obligation in cash, shares of its common stock, or a combination of cash and shares of its common stock, at its election. In connection with the issuance of the 2021 Notes, the company also paid $27.3 million to enter into privately negotiated capped call transactions with the initial purchasers and/or affiliates of the initial purchasers. The capped call transactions will cover, subject to customary anti-dilution adjustments, the number of shares of the company’s common stock that will initially underlie the 2021 Notes. The capped call transactions will effectively raise the conversion premium on the 2021 Notes from approximately 22.5% to approximately 60%, which raises the initial conversion price from approximately $9.76 per share of common stock to approximately $12.75 per share of common stock. The capped call transactions are expected to reduce potential dilution to the company’s common stock and/or offset potential cash payments the company is required to make in excess of the principal amount upon any conversion of the 2021 Notes. Interest expense related to the 2021 Notes is comprised of the following:
Revolving Credit Facility The company has a secured revolving credit facility (the “Credit Agreement”) that provides for loans and letters of credit. During the second quarter of 2018, the maximum amount available under the facility was increased from $125.0 million to$145.0 million (with a limit on letters of credit of $30.0 million). The accordion feature contained in the Credit Agreement that permitted this increase allows for an increase in the amount of the facility up to $150.0 million. Availability under the credit facility is subject to a borrowing base calculated by reference to the company’s receivables. At December 31, 2018, the company had no borrowings and $6.5 million of letters of credit outstanding, and availability under the facility was $138.5 million net of letters of credit issued. The Credit Agreement expires October 5, 2022, subject to a springing maturity (i) on the date that is 91 days prior to the maturity date of the 2021 Notes unless, on such date, certain conditions are met; or (ii) on the date that is 60 days prior to the maturity date of the 2022 Notes unless, by such date, such secured notes have not been redeemed or refinanced. The credit facility is guaranteed by Unisys Holding Corporation, Unisys NPL, Inc., Unisys AP Investment Company I 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 credit facility falls below the greater of 10% of the lenders’ commitments under the facility and $15.0 million. The Credit Agreement contains customary representations and warranties, including that there has been no material adverse change in the company’s business, properties, operations or financial condition. The Credit Agreement includes limitations 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. 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. At December 31, 2018, the company has met all covenants and conditions under its various lending agreements. The company expects to continue to meet these covenants and conditions. The company’s principal sources of liquidity are cash on hand, cash from operations and its revolving credit facility, discussed above. The company and certain international subsidiaries have access to uncommitted lines of credit from various banks. The company’s anticipated future cash expenditures include anticipated contributions to its defined benefit pension plans. The company believes that it has adequate sources of liquidity to meet its expected 2019 cash requirements. |

| Employee plans | 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, 2018, 2.4 million shares of unissued common stock of the company were available for granting under these plans. As of December 31, 2018, the company has granted non-qualified stock options 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, 2018, 2017 and 2016, the company recognized $13.2 million, $11.2 million and $9.5 million of share-based compensation expense, which is comprised of $13.1 million, $10.1 million and $7.5 million of restricted stock unit expense and $0.1 million, $1.1 million and $2.0 million of stock option expense, respectively. There were no grants of stock option awards for the years ended December 31, 2018 and 2017. In 2016, the company granted 11 thousand stock option awards. The weighted-average fair value of the grant, which was estimated using the Black-Scholes option pricing model was $4.53. As of December 31, 2018, 1.1 million stock option awards with a weighted-average exercise price of $27.90 are outstanding. 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. Time-based 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 unit activity for the year ended December 31, 2018 follows (shares in thousands):
The aggregate weighted-average grant-date fair value of restricted stock units granted during the years ended December 31, 2018, 2017 and 2016 was $17.9 million, $14.4 million and $12.9 million, respectively. The fair value of 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.
As of December 31, 2018, there was $12.2 million of total unrecognized compensation cost related to outstanding restricted stock units granted under the company’s plans. That cost is expected to be recognized over a weighted-average period of 1.9 years. The aggregate weighted-average grant-date fair value of restricted stock units vested during the years ended December 31, 2018, 2017 and 2016 was $10.4 million, $7.4 million and $3.5 million, respectively. Common stock issued upon exercise of stock options or upon lapse of restrictions on restricted stock units are newly issued shares. During 2018 and 2017, the company did not recognize any tax benefits from the exercise of stock options or upon issuance of stock upon lapse of restrictions on restricted stock units because of its tax position. Any such tax benefits resulting from tax deductions in excess of the compensation costs recognized are classified as operating cash flows. 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, 2018, 2017 and 2016, was $11.1 million, $10.8 million and $10.7 million, respectively. The company has defined contribution plans in certain locations outside the United States. The charge to income related to these plans was $21.3 million, $18.5 million and $19.0 million, for the years ended December 31, 2018, 2017 and 2016, 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, 2018 and 2017, the liability to the participants of these plans was $11.6 million and $13.4 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., U.K. and the Netherlands, accrual of future benefits under the plans has ceased. During 2018, cash lump-sum payments were paid to certain plan participants in two of the company’s international defined benefit pension plans which resulted in a non-cash pension settlement charge of $6.4 million for the year ended December 31, 2018. Retirement plans’ funded status and amounts recognized in the company’s consolidated balance sheets at December 31, 2018 and 2017 follows:
Information for defined benefit retirement plans with an accumulated benefit obligation in excess of plan assets at December 31, 2018 and 2017 follows:
Information for defined benefit retirement plans with a projected benefit obligation in excess of plan assets at December 31, 2018 and 2017 follows:
Net periodic pension cost (income) for 2018, 2017 and 2016 includes the following components:
(i) Service cost is reported in cost of revenue - services and selling, general and administrative expenses. All other components of net periodic pension cost are reported in other income (expense), net in the consolidated statements of income. Weighted-average assumptions used to determine net periodic pension cost for the years ended December 31 were as follows:
The company’s investment policy targets and ranges for each asset category are as follows:
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 primarily in equity securities in the U.S. and for international plans by investing in appropriate asset classes, subject to the constraints of each plan 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. plan 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 2019, the company expects to make cash contributions of $105.6 million to its worldwide defined benefit pension plans, which are comprised of $38.4 million primarily for international defined benefit pension plans and $67.2 million for the company’s U.S. qualified defined benefit pension plans. As of December 31, 2018, the following benefit payments are expected to be paid from the defined benefit pension plans:
Other postretirement benefits A reconciliation of the benefit obligation, fair value of the plan assets and the funded status of the postretirement benefit plans at December 31, 2018 and 2017, follows:
Net periodic postretirement benefit cost for 2018, 2017 and 2016, follows:
(i) Service cost is reported in selling, general and administrative expenses. All other components of net periodic benefit cost are reported in other income (expense), net in the consolidated statements of income. Weighted-average assumptions used to determine net periodic postretirement benefit cost for the years ended December 31 were as follows:
Weighted-average assumptions used to determine benefit obligation at December 31 were as follows:
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 2019, the company expects to contribute approximately $8 million to its postretirement benefit plans.
As of December 31, 2018, the following benefits are expected to be paid from the company’s postretirement 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 90 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, 2018.
(i) Level 1 derivatives represent unrealized appreciation or depreciation on open futures contracts. The value of open futures contracts includes derivatives and the cumulative futures contracts variation margin received from brokers. (ii) Investments measured at fair value using NAV as a practical expedient have not been classified in the fair value hierarchy. The fair value amounts presented in this table for these investments are included to permit reconciliation of the fair value hierarchy to the total plan assets. The following table sets forth by level, within the fair value hierarchy, the plans’ assets (liabilities) at fair value at December 31, 2017.
(i) Investments measured at fair value using NAV as a practical expedient have not been classified in the fair value hierarchy. The fair value amounts presented in this table for these investments are included to permit reconciliation of the fair value hierarchy to the total plan assets. The following table sets forth a summary of changes in the fair value of the plans’ Level 3 assets for the year ended December 31, 2018.
The following table sets forth a summary of changes in the fair value of the plans’ Level 3 assets for the year ended December 31, 2017.
The following table presents additional information about plan assets valued using the net asset value as a practical expedient within the fair value hierarchy table.
(i) Includes investments in private real estate funds and limited partnerships. The funds invest in U.S. real estate and allow redemptions quarterly, though queues, restrictions and gates may extend the period. The limited partnerships include investments in primarily U.S. real estate, and can never be redeemed. The partnerships are all currently being wound up, and are expected to make all distributions over the next year. (ii) Includes investments in limited partnerships, which invest primarily in U.S. buyouts and venture capital. The investments can never be redeemed. The partnerships are all currently being wound up, and are expected to make all distributions over the next three years. |

Litigation and contingencies |

| Commitments and Contingencies Disclosure [Abstract] | |
| Litigation and contingencies | 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 flows could be materially affected in any particular period by the resolution of one or more of the legal matters pending against it. In April 2007, the Ministry of Justice of Belgium sued Unisys Belgium SA-NV, a Unisys subsidiary (“Unisys Belgium”), in the Court of First Instance of Brussels. The Belgian government had engaged the company to design and develop software for a computerized system to be used to manage the Belgian court system. The Belgian State terminated the contract and in its lawsuit has alleged that the termination was justified because Unisys Belgium failed to deliver satisfactory software in a timely manner. It claims damages of approximately €28.0 million. Unisys Belgium filed its defense and counterclaim in April 2008, in the amount of approximately €18.5 million. The company believes it has valid defenses to the claims and contends that the Belgian State’s termination of the contract was unjustified. 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, 2018, 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 $101.0 million. On June 26, 2014, the State of Louisiana filed a Petition for Damages against, among other defendants, the company and Molina Information Systems, LLC, in the Parish of East Baton Rouge, 19th Judicial District. The State alleged that between 1989 and 2012 the defendants, each acting successively as the State’s Medicaid fiscal intermediary, utilized an incorrect reimbursement formula for the payment of pharmaceutical claims causing the State to pay excessive amounts for prescription drugs. The State contends overpayments of approximately $68.0 million for the period January 2002 through July 2011 and sought data to identify the claims at issue for the remaining time period. On August 14, 2018, the Louisiana Court of Appeal for the First Circuit dismissed the case. On September 27, 2018, the Court denied the State’s motion for a rehearing. On October 26, 2018, the State applied for a writ of review to the Louisiana Supreme Court, which was granted on January 18, 2019. The Louisiana Supreme Court will calendar the case for further briefing. 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, 2018, it has adequate provisions for any such matters. |

| Segment information | Segment information As described in Note 2, effective January 1, 2018, the company adopted the requirements of Topic 606 which resulted in an adjustment to Technology revenue and profit of $53.0 million in the first quarter of 2018. The adjustment represents revenue from software license extensions and renewals, which were contracted for in the fourth quarter of 2017 and properly recorded as revenue at that time under the revenue recognition rules then in effect (Topic 605). Topic 606 requires revenue related to software license renewals or extensions to be recorded when the new license term begins, which in the case of the $53.0 million, is January 1, 2018. Effective January 1, 2018, the company changed the grouping of certain of its classes of services. As a result, prior-periods’ customer revenue by classes of similar services have been reclassified to conform to the current-year period. The company has two business segments: Services and Technology. Revenue classifications within the Services and Technology segment are as follows:
The accounting policies of each business 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 Technology segment recognizes intersegment revenue and manufacturing profit on software and hardware shipments to customers under Services contracts. The Services segment, in turn, recognizes customer revenue and marketing profits on such shipments of company software and hardware to customers. The Services segment also includes the sale of software and hardware products sourced from third parties that are sold to customers through the company’s Services channels. In the company’s consolidated statements of income, the manufacturing costs of products sourced from the Technology segment and sold to Services customers are reported in cost of revenue for Services. Also included in the Technology segment’s sales and operating profit are sales of software and hardware sold to the Services segment for internal use in Services engagements. The amount of such profit included in operating income of the Technology segment for the years ended December 31, 2018, 2017 and 2016 was $4.2 million, $6.3 million and $0.7 million, respectively. The profit on these transactions is eliminated in Corporate. The company evaluates business segment performance based on operating income exclusive of postretirement income or expense, restructuring charges and unusual and nonrecurring items, which are included in Corporate. All other corporate and centrally incurred costs are allocated to the business segments based principally on revenue, employees, square footage or usage. No single customer accounts for more than 10% of revenue. Revenue from various agencies of the U.S. Government, which is reported in both business segments, was approximately $574 million, $571 million and $564 million in 2018, 2017 and 2016, respectively. Corporate assets are principally cash and cash equivalents, prepaid postretirement assets and deferred income taxes. The expense or income related to corporate assets is allocated to the business segments. Customer revenue by classes of similar products or services, by segment, is presented below:

| Use of estimates | Use of estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles 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 accounts receivable, inventories, outsourcing assets, marketable software, goodwill and other long-lived assets, legal contingencies, indemnifications, assumptions used in the measurement of progress toward completion 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 significantly 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. |

| Shipping and handling and Revenue recognition | 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. 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. 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. 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 time and materials service contracts and outsourcing contracts is recognized as the services are provided using either an objective measure of output or on a straight-line basis over the term of the contract. The company also enters into multiple-element arrangements, which 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. To the extent that a performance obligation in a multiple-deliverable arrangement is subject to specific guidance, that performance obligation is accounted for in accordance with such specific guidance. An example of such an arrangement may include leased assets which are subject to specific leasing accounting guidance. In multiple-element arrangements, the company allocates the total transaction price to be earned under the arrangement among the various performance obligations in proportion to their standalone selling prices (relative standalone selling price basis). 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. Many of the company’s contracts have a single performance obligation as the promise to transfer the individual goods or services is not separately identifiable from other promises in the contracts and, therefore, not distinct. 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 Services segment, 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 Technology segment, substantially all of the company’s goods and services 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. At December 31, 2018, the company had approximately $1.2 billion of remaining performance obligations of which approximately 40% is estimated to be recognized as revenue by the end of 2019. The company does not disclose the value of unsatisfied performance obligations for (1) contracts with an original expected length of one year or less and (2) contracts for which the company recognizes revenue at the amount to which it has the right to invoice for services performed. The company discloses disaggregation of its customer revenue by geographic areas and by classes of similar products and services, by segment (see note 17). The timing of revenue recognition, billings and cash collections results in billed accounts receivable, unbilled receivables, contract assets and deferred revenue (contract liabilities). The disclosure of contract assets is a new requirement due to the adoption of Topic 606. At December 31, 2017, contract assets were included in accounts receivable, net on the company’s consolidated balance sheet. At December 31, 2018, $22.2 million of long-term contract assets were included in other long-term assets on the company’s consolidated balance sheet. At December 31, 2018, deposit liabilities of $21.2 million were principally included in current deferred revenue. These deposit liabilities represent upfront consideration received from customers for services such as post-contract support and maintenance that allow the customer to terminate the contract at any time for convenience. Significant changes during 2018 in the above contract asset and liability balances were as follows: revenue of $307.1 million was recognized that was included in deferred revenue at December 31, 2017. 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. At December 31, 2018 and December 31, 2017, the company had $12.1 million and $11.0 million, respectively, of deferred commissions. For the year ended December 31, 2018, $6.9 million of amortization expense related to deferred commissions was recorded in selling, general and administrative expense in the company’s consolidated statement of income. Costs to fulfill a contract, which are incurred upon initiation of certain services contracts and are related to initial customer setup, are included in outsourcing assets, net in the company’s consolidated balance sheet. The amount of such cost at December 31, 2018 and December 31, 2017 was $79.5 million and $76.0 million, respectively. These costs are amortized over the initial contract life and reported in Services cost of sales. During 2018, $21.7 million was amortized. Recoverability of these costs are 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 cash flows could differ from these estimates. Shipping and handling Costs related to shipping and handling are included in cost of revenue. |

| Goodwill | Goodwill Goodwill arising from the acquisition of an entity represents the excess of the cost of acquisition over the fair value of the acquired identifiable assets, liabilities and contingent liabilities of the entity recognized at the date of acquisition. Goodwill is initially recognized as an asset and is subsequently measured at cost less any accumulated impairment losses. Goodwill is held in the currency of the acquired entity and revalued to the closing rate at each balance sheet date. The company tests goodwill for impairment annually in the fourth quarter using data as of September 30th 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 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 in the period the impairment is identified. The company estimates the fair value of each reporting unit using a combination of the income approach and 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 gave more weighting to the income approach. The higher weighting assigned to the income approach took 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. |

| Income taxes | 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. 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. The company treats the global intangible low-taxed 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. |

| Marketable software | 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, which is generally 3 years following product release. The company continually reassesses the estimated revenue-producing lives of the products and will revise the lives as necessary. The company performs quarterly reviews to ensure that unamortized costs remain recoverable from future revenue. |

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 outsourcing assets is subject to various business risks. Quarterly, the company compares the carrying value of the outsourcing assets with the undiscounted future cash flows expected to be generated by the outsourcing assets to determine if there is impairment. If impaired, the outsourcing 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. |

| Translation of foreign currency | 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 on intercompany balances are reported in other income (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 translation are included in other income (expense), net. |

| Stock-based compensation plans | 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 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 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 company estimates the fair value of stock options using a Black-Scholes valuation model. The expense is recorded in selling, general and administrative expenses. |

| Retirement benefits | 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. 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. 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. |

| Fair value measurements | 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 long-term debt (see note 12), derivatives (see note 9) and to its postretirement plan assets (see note 14). |

| Recent accounting pronouncements and accounting changes | Accounting Pronouncements Adopted Effective January 1, 2018, the company adopted ASU No. 2017-07 Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost issued by the Financial Accounting Standards Board (“FASB”) which requires employers to present the service cost component of net periodic benefit cost in the same income statement line item(s) as other employee compensation costs arising from services rendered during the period. The other components of net periodic benefit cost are presented separately from the line items that include service cost and outside the subtotal of operating income. ASU No. 2017-07 allows a practical expedient that permits an entity to use amounts disclosed in its pension and other postretirement benefit plan footnote for the prior comparative periods as the estimation basis for applying the retrospective presentation requirements. The new guidance has been applied on a retrospective basis, using the practical expedient, whereby prior-period financial statements have been adjusted to reflect the adoption of the new guidance, as required by the FASB. For the years ended December 31, 2017 and 2016, $92.5 million and $81.6 million, respectively, of net periodic benefit cost other than service cost, was reclassified from cost of revenue, selling, general and administrative expenses and research and development expenses to other income (expense), net in the company’s consolidated results of operations (see note 14). Effective January 1, 2018, the company adopted ASU No. 2014-09 Revenue from Contracts with Customers (Topic 606) issued by the FASB which establishes principles that an entity shall apply to report useful information to users of financial statements about the nature, amount, timing and uncertainty of revenue and cash flows from a contract with a customer. Topic 606 allows for either “full retrospective” adoption, meaning the standard is applied to all periods presented, or “modified retrospective” adoption, meaning the standard is applied only to the most current period presented in the financial statements. Topic 606 requires the company to recognize revenue for certain transactions, including extended payment term software licenses and short-term software licenses, sooner than the prior rules would allow and requires the company to recognize software license extensions and renewals (the most significant impact upon adoption), later than the prior rules would allow. Topic 606 also requires significantly expanded disclosure requirements. The company has adopted the standard using the modified retrospective method and applied the standard to all contracts that were not completed as of January 1, 2018. The cumulative effect of the adoption was recognized as an increase in the company’s accumulated deficit of $21.4 million on January 1, 2018. The following table summarizes the effects of adopting ASU No. 2014-09 on the company’s consolidated financial statements as of and for the year ended December 31, 2018.
Included in the Technology revenue adjustments for the year ended December 31, 2018 in the above table is $53.0 million of revenue from software license extensions and renewals which were contracted for in the fourth quarter of 2017 and properly recorded as revenue at that time under the revenue recognition rules then in effect (Topic 605). Upon adoption of the new revenue recognition rules (Topic 606) on January 1, 2018, and since the company adopted Topic 606 under the modified retrospective method whereby prior periods were not restated, the company was required to include this $53.0 million in the cumulative effect adjustment to retained earnings on January 1, 2018. Topic 606 requires revenue related to software license renewals or extensions to be recorded when the new license term begins, which in the case of the $53.0 million is January 1, 2018. The company has excluded revenue and related profit for these software licenses to reflect the balances without the adoption of Topic 606 in the above table. This is a one-time adjustment and it will not reoccur in future periods. There are additional adjustments being made in the above table, but they do not represent previously recorded revenue. Those additional adjustments represent other differences between Topic 605 and Topic 606, principally extended payment term software licenses and short-term software licenses both of which are recorded at the inception of the license term under Topic 606, but were required to be recognized ratably over the software license term under Topic 605. An additional adjustment is that under Topic 605, a company was not able to recognize software license revenue until the last software license is delivered due to the lack of vendor specific objective evidence, whereas under Topic 606, a company is required to use the standalone selling price for all performance obligations. This resulted in software license revenue being recognized sooner under Topic 606 compared with Topic 605. In 2018, the company adopted ASU No. 2017-05 Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20) issued by the FASB which clarifies the scope and application of ASC 610-20 on the sale or transfer of nonfinancial assets and in substance nonfinancial assets to noncustomers, including partial sales. The company adopted the standard using the modified retrospective method. The cumulative effect of the adoption was recognized as a decrease in the company’s accumulated deficit of $6.3 million. Effective July 1, 2018, the company adopted ASU No. 2018-02 Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income by applying the changes in the period of adoption. The new guidance permits companies to reclassify stranded tax effects in accumulated other comprehensive income (“AOCI”) caused by the U.S. Tax Cuts and Jobs Act of 2017 (“TCJA”) to retained earnings. Upon enactment of the TCJA, the U.S. corporate tax rate was reduced from 35% to 21% and the Company's U.S. deferred tax balances and related valuation allowances were remeasured to the lower enacted U.S. corporate tax rate. In accordance with its accounting policy, the company releases the income tax effects of deferred tax balances that have a valuation allowance from AOCI once the reason the tax effects were established cease to exist (e.g. postretirement plan is liquidated). The new guidance allows for the reclassification of stranded tax effects as a result of the change in tax rates from the TCJA to be recorded upon adoption of the guidance rather than at cessation date. On July 1, 2018, $208.7 million related to postretirement plans was reclassified from AOCI to retained earnings. In September 2018, the company adopted SEC Release No. 33-10532, Disclosure Update and Simplification which amends certain disclosure requirements that were redundant, duplicative, overlapping, outdated or superseded. In addition, the rule expands the disclosure requirements on changes in stockholders’ equity for interim periods. Under this rule, a reconciliation of changes in stockholders' equity is required for each period for which an income statement is presented. The company applied the new disclosure requirements retrospectively to all periods presented. There was no overall impact on the company’s consolidated financial statements. Effective for the annual reporting period ended December 31, 2018, the company adopted 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 which adds, removes and clarifies disclosure requirements related to defined benefit pension and other postretirement plans. The company applied the changes on a retrospective basis for all periods presented. There was no overall impact on the company’s consolidated financial statements. Accounting Pronouncements Not Yet Adopted In August 2018, the FASB issued ASU No. 2018-15, Intangibles - Goodwill and Other - Internal - Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract which clarifies the accounting for implementation costs incurred in a cloud computing arrangement that is a service contract. This update is effective for fiscal years ending after December 15, 2019, with earlier adoption permitted. The new guidance can be applied retrospectively or prospectively to all implementation costs incurred after the date of adoption. The company is currently assessing when it will choose to adopt, and is currently evaluating the impact of the adoption on its consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13 Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments which introduces a new model for recognizing credit losses on financial instruments based on an estimate of current expected losses. This includes trade and other receivables, loans and other financial instruments. This update is effective for annual periods beginning after December 15, 2019, with earlier adoption permitted. The company is currently assessing when it will choose to adopt, and is currently evaluating the impact of the adoption on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02 Leases (Topic 842), which is intended to improve financial reporting about leasing transactions. The ASU requires organizations that lease assets, referred to as lessees, to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. The standard also requires disclosures to help investors and other financial statement users better understand the amount, timing and uncertainty of cash flows arising from leases. In July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842), Targeted Improvements, which provides an alternative transition method permitting the recognition of a cumulative-effect adjustment to retained earnings on the date of adoption rather than restating comparative periods in transition as originally prescribed by Topic 842. The standard is effective for annual reporting periods beginning after December 15, 2018, which for the company is January 1, 2019. The company will adopt the new guidance utilizing the alternative transition method. The company reviewed lease contracts, implemented new lease accounting software, established new processes and internal controls and evaluated the impact of certain accounting policy elections. The adoption is expected to have a material impact on the consolidated financial position, and is not expected to have a material impact on the consolidated results of operations and cash flows. |
