Organization, Consolidation and Presentation of Financial Statements [Abstract]
New Accounting Pronouncements	New Accounting Pronouncements - Standards Adopted in 2017 In January 2017, the Financial Accounting Standard Board (FASB) issued Accounting Standard Update (ASU) 2017-04, Intangibles - Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment, which eliminates Step 2 of the current two-step goodwill impairment test and requires only a one-step quantitative impairment test, whereby a goodwill impairment loss will be measured as the excess of a reporting unit’s carrying amount over its fair value (not to exceed the total goodwill allocated to that reporting unit). The ASU is effective for interim and annual periods beginning after December 15, 2019, and is required to be applied prospectively. We elected to early adopt this standard effective January 1, 2017. The adoption of this standard had no impact on our consolidated financial statements or disclosures. In March 2016, the FASB issued ASU 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The standard includes multiple provisions intended to simplify various aspects of the accounting for share-based payments. We retroactively adopted this ASU effective January 1, 2017. Accordingly, the Condensed Consolidated Statement of Cash Flows for the nine months ended September 30, 2016 has been recast to increase both net cash provided by operating activities and net cash used in financing activities by $5 million. In July 2015, the FASB issued ASU 2015-11, Inventory - Simplifying the Measurement of Inventory, which requires inventory to be measured at the lower of cost and net realizable value (estimated selling price less reasonably predictable costs of completion, disposal and transportation). Inventory measured using the last-in, first-out (LIFO) basis is not impacted by the new guidance. This standard became effective January 1, 2017 and there was no impact on our consolidated financial statements or disclosures. New Accounting Pronouncements - Standards Not Yet Adopted In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The ASU changes the recognition and presentation requirements of hedge accounting and reduces the cost and complexity of applying hedge accounting by easing the requirements for effectiveness testing and hedge documentation. The standard is effective for interim and annual periods beginning after December 15, 2018 and early adoption is permitted. We are currently assessing the impact this standard will have on our consolidated financial statements. In May 2017, the FASB issued ASU 2017-09, Scope of Modification Accounting. The ASU provides guidance about which changes to terms and conditions of a share-based payment award require an entity to apply modification accounting. The standard is effective for interim and annual periods beginning after December 15, 2017 and would be applied prospectively to awards modified on or after the effective date. We do not expect the adoption of this standard will have any impact on our consolidated financial statements. In March 2017, the FASB issued ASU 2017-08, Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. The ASU shortens the amortization period for certain callable debt securities held at a premium, requiring the premium to be amortized to the earliest call date. The standard will be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The standard is effective for interim and annual periods beginning after December 15, 2018 and early adoption is permitted. We are currently assessing the impact this standard will have on our consolidated financial statements. In March 2017, the FASB issued ASU 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Benefit Cost. The ASU requires the service cost component of net periodic benefit cost to be presented in the same income statement line item as other employee compensation costs arising from services rendered during the period. Other components of the net periodic benefit cost are to be presented separately, in an appropriately titled line item outside of any subtotal of operating income or disclosed in the footnotes. The standard also limits the amount eligible for capitalization to the service cost component. The standard is effective for interim and annual periods beginning after December 15, 2017 and we are currently assessing the impact this standard will have on our consolidated financial statements. In January 2017, the FASB issued ASU 2017-06 – Plan Accounting: Defined Benefit Pension Plans (Topic 960); Defined Contribution Pension Plans (Topic 962); Health and Welfare Benefit Plans (Topic 965): Employee Benefit Plan Master Trust Reporting. The ASU requires separate disclosure in the statement of net assets available for benefits and the statement of changes in net assets available for benefits of changes in any interests held in a Master Trust and other enhanced disclosures. The standard is effective for interim and annual periods beginning after December 15, 2018 and we are currently evaluating the impact of this standard on our consolidated financial statements. In January 2017, the FASB issued ASU 2017-01, Clarifying the Definition of a Business, which clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The standard is effective for interim and annual periods beginning after December 15, 2017. The impact on our consolidated financial statements will depend on the facts and circumstances of any specific future transactions. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes: Inter-entity Transfers of Assets other than Inventory, which requires tax expense to be recognized from the sale of intra-entity assets, other than inventory, when the transfer occurs, even though the effects of the transaction are eliminated in consolidation. Under current guidance, the tax effects of transfers are deferred until the transferred asset is sold or otherwise recovered through use. The standard is effective for interim and annual periods beginning after December 15, 2017 and early adoption is permitted, including adoption during an interim period. We are currently assessing the impact this standard will have on our consolidated financial statements. In August, 2016, the FASB issued ASU No. 2016-15, Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force). The ASU is intended to reduce diversity in practice in the presentation and classification of certain cash receipts and cash payments by providing guidance on eight specific cash flow issues. The ASU is effective for interim and annual periods beginning after December 15, 2017 and early adoption is permitted, including adoption during an interim period. We are currently assessing the impact this standard will have on our consolidated statement of cash flows. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses. The ASU sets forth a “current expected credit loss” (CECL) model which requires companies to measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions and reasonable supportable forecasts. This replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost and applies to some off-balance sheet credit exposures. This standard is effective for interim and annual periods beginning after December 15, 2019. We are currently assessing the impact this standard will have on our consolidated financial statements and disclosures. In February 2016, the FASB issued ASU 2016-02, Leases. This standard, among other things, will require lessees to recognize almost all leases on their balance sheet as a right-of-use asset and a lease liability and result in enhanced disclosures. The standard is effective for interim and annual periods beginning after December 15, 2018 and early adoption is permitted. We are currently assessing the impact this standard will have on our consolidated financial statements and disclosures. In January 2016, the FASB issued ASU 2016-01, Financial Instruments–Overall: Recognition and Measurement of Financial Assets and Financial Liabilities. This standard primarily affects the accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. The standard is effective for interim and annual periods beginning after December 15, 2017, and early adoption is permitted. We are currently assessing the impact this standard will have on our consolidated financial statements and disclosures. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which requires companies to recognize revenue for the transfer of goods and services to customers in amounts that reflect the consideration the company expects to receive in exchange for those goods and services. In addition, the standard requires enhanced disclosures about the nature, amount, timing and uncertainty of revenue. There were several amendments to the standard during 2016. The standard is effective beginning January 1, 2018 and can be adopted either retrospectively to each reporting period presented or on a modified retrospective basis with a cumulative effect adjustment at the date of the initial application. We plan to adopt the standard on the modified retrospective basis with a cumulative effect adjustment. We have substantially completed our assessment of all potential impacts of the standard and do not expect a change in revenue recognition for the majority of our product and service offerings. The standard will have the most impact on timing of certain revenues in our Software Solutions segment. Specifically, we have concluded that for certain data subscription offerings, the portion of the transaction price allocated to the initial data set will be recognized as revenue at the time of initial delivery rather than over the subscription period. We also concluded that for certain software licenses, revenue will be recognized ratably over the specific contract terms rather than predominately at the time of billing and delivery. Also, we concluded that certain marketing costs associated with the acquisition of new customers will be expensed as incurred rather than recognized over their expected revenue stream of eight years. We have also determined that certain sales commission plans will qualify for capitalization under the new standard. We plan to use the practical expedient that allows companies to expense costs to obtain a contract when the estimated amortization period is less than one year. We expect to complete our quantitative assessment of these key changes and the impact on our consolidated financial statements during the fourth quarter of 2017. We continue to develop our internal controls, accounting policies and new disclosure requirements. We are enhancing our current systems and business processes to facilitate the preparation of financial information that will be required under the new standard. We expect to finalize these activities by the end of the year.
