Organization, Consolidation and Presentation of Financial Statements [Abstract] |
Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Interim Financial Statements The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (GAAP) for interim financial information and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair statement of the results for interim periods have been included. Results for interim periods should not be considered indicative of results for a full year. These interim Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and Notes thereto contained in the company’s Annual Report on Form 10-K for the year ended December 31, 2016, collectively referred to as the “2016 Annual Report.” The Consolidated Financial Statements include the accounts of the company and all of its subsidiaries in which a controlling interest is maintained. Basis of Presentation Certain reclassifications of prior year's data have been made to conform to current year's presentation. As noted below under “Recent Accounting Pronouncements”, effective January 1, 2017, the company adopted the Financial Accounting Standards Board (FASB) Accounting Standards Update (ASU) No. 2016-09, Compensation - Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting. In conjunction with the adoption of this ASU, the company retrospectively reclassified cash flows related to income tax impacts associated with employee share-based payments in the interim Condensed Consolidated Statements of Cash Flows, as described below. Recent Accounting Pronouncements Accounting Pronouncements Implemented in 2017 In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting, which modifies the accounting for certain aspects of share-based payments to employees. The new guidance requires excess tax benefits and tax deficiencies to be recorded in the income statement when stock awards vest or are settled. In addition, cash flows related to excess tax benefits will no longer be separately classified as a financing activity apart from other income tax cash flows. The standard also allows the company to repurchase more of an employee’s vested shares for tax withholding purposes without triggering liability accounting, and clarifies that all cash payments made to tax authorities on an employee’s behalf for withheld shares should be presented as a financing activity on the statement of cash flows. The company adopted this standard as of January 1, 2017. The primary impact of adoption was the recognition of excess tax benefits in the company's provision for income taxes rather than additional paid-in capital, which is applied prospectively in accordance with the guidance. Adoption of the new standard resulted in the recognition of $20 of excess tax benefits in the company's provision for income taxes rather than additional paid-in capital for the quarter ended March 31, 2017. The company elected to apply the presentation requirements for cash flows related to excess tax benefits retrospectively to all periods presented which resulted in a decrease to both net cash used for operating activities and net cash provided by financing activities of $20 and $15 for quarters ended March 31, 2017 and 2016, respectively. The presentation requirements for cash flows related to employee taxes paid for withheld shares resulted in a decrease to both net cash used for operating activities and net cash provided by financing activities of $26 and $23 for the quarters ended March 31, 2017 and 2016, respectively. The remaining updates required by this standard did not have a material impact to the company’s interim Consolidated Financial Statements. New Accounting Pronouncements to be Implemented In March 2017, the FASB issued ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715), Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The new guidance requires registrants to present the service cost component of net periodic benefit cost in the same income statement line item or items as other employee compensation costs arising from services rendered during the period. In addition, only the service cost component will be eligible for capitalization in assets. Registrants will present the other components of net periodic benefit cost separately from the service cost component; and, the line item or items used in the income statement to present the other components of net periodic benefit cost must be disclosed. The guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted as of the beginning of an annual period. The new standard must be adopted retrospectively for the presentation of the service cost component and the other components of net periodic benefit cost in the income statement, and prospectively for the capitalization of the service cost component of net periodic benefit cost in assets. The company plans to adopt this guidance in the first quarter of 2018 and is currently evaluating the impact on the Consolidated Financial Statements and related disclosures. See Note 14 for the components of net periodic benefit cost. In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment. The new guidance eliminates the requirement to determine the fair value of individual assets and liabilities of a reporting unit to measure goodwill impairment. Under the amendments in the new ASU, goodwill impairment testing will be performed by comparing the fair value of the reporting unit with its carrying amount and recognizing an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. The new standard is effective for annual and interim goodwill impairment tests in fiscal years beginning after December 15, 2019, and should be applied on a prospective basis. Early adoption is permitted for annual or interim goodwill impairment testing performed after January 1, 2017. The company is currently evaluating the timing of adoption. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805), Clarifying the Definition of a Business. The new guidance narrows the existing definition of a business and provides a framework for evaluating whether a transaction should be accounted for as an acquisition (or disposal) of assets or a business. The guidance requires an entity to evaluate if substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets; if so, the set of transferred assets and activities (collectively, the set) is not a business. To be considered a business, the set would need to include an input and a substantive process that together significantly contribute to the ability to create outputs, as defined by the ASU. The guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within those annual reporting periods, and should be applied prospectively. Early adoption is permitted. The company will apply this guidance to applicable transactions after the adoption date. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740), Intra-Entity Transfers of Assets Other Than Inventory. The new guidance requires that entities recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs, rather than when the asset is sold to an outside party. The guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within those annual reporting periods. Early adoption is permitted as of the beginning of an annual reporting period. The new guidance requires adoption on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The company plans to adopt this guidance in the first quarter of 2018 and is currently evaluating the impact this guidance will have on the Consolidated Financial Statements and related disclosures. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments. The new guidance makes eight targeted changes to how cash receipts and cash payments are presented and classified in the statement of cash flows. The guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity that elects early adoption must adopt all of the amendments in the same period. The new guidance requires adoption on a retrospective basis unless it is impracticable to apply, in which case the company would be required to apply the amendments prospectively as of the earliest date practicable. The company is currently evaluating the impact this guidance will have on the Consolidated Financial Statements and related disclosures, but does not expect there to be a significant impact. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The amendments under the new guidance will require lessees to recognize almost all leases on their balance sheet as a right-of-use asset and a lease liability, other than leases that meet the definition of a short-term lease. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as either operating or finance. Classification will be based on criteria that are largely similar to those applied in current lease accounting. Lessor accounting is similar to the current model, but updated to align with certain changes to the lessee model and the new revenue recognition standard. The new leasing standard will be effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. The new standard must be adopted using a modified retrospective transition, requiring application at the beginning of the earliest comparative period presented. The company is currently evaluating the impact of adopting this guidance on its financial position and results of operations. The company is the lessee under various agreements for facilities and equipment that are currently accounted for as operating leases. A complete discussion of these leases is included in the company's 2016 Annual Report in Note 15, "Commitments and Contingent Liabilities." In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which was further updated in March, April, May and December 2016. The new guidance clarifies the principles for recognizing revenue and develops a common revenue standard for GAAP. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. The new standard also will result in additional disclosure requirements to describe the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. In July 2015, the FASB approved a deferral of the ASU effective date from annual and interim periods beginning after December 15, 2016 to annual and interim periods beginning after December 15, 2017. The company continues to evaluate the impact of the new standard on its Consolidated Financial Statements and disclosures. Based on the analysis conducted to date, the company does not believe the impact upon adoption will be material to its Consolidated Financial Statements. The company plans to adopt the standard in the first quarter of 2018 under the modified retrospective transition method.
