Accounting Policies [Abstract] |
Principles of consolidation | Principles of consolidation The consolidated financial statements include the accounts of all majority-owned subsidiaries.
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.
Cash and Cash equivalents | 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hand, short-term investments purchased with a maturity of three months or less and certificates of deposit which may be withdrawn at any time at the discretion of the company without penalty.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.
Inventories | 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 Properties are carried at cost and are depreciated over the estimated lives of such assets using the straight-line method.
Advertising costs | Advertising costs All advertising costs are expensed as incurred.
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.
Internal-use software | 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 | 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 | 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).
Noncontrolling interest | 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 | 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.
