New Accounting Pronouncements and Changes in Accounting Principles [Abstract] |
Recent Accounting Standards [Text Block] | Note 3: Recent Accounting Standards We assess the adoption impacts of recently issued accounting standards by the Financial Accounting Standards Board on our financial statements. The tables below describe impacts from newly issued standards as well as material updates to our previous assessments, if any, from our 2016 Form 10-K. Accounting Standards Adopted
Standard/Description | Effective Date and Adoption Considerations | Effect on Financial Statements or Other Significant Matters
Intangibles - Goodwill and Other - Simplifying the Test for Goodwill Impairment. This accounting standard update eliminates Step 2 from the existing guidance to simplify how goodwill impairment tests are performed. With the elimination of this step, a goodwill impairment test is performed by comparing the fair value of a reporting unit to its carrying value. An impairment charge is recognized for the amount by which the reporting unit's carrying value exceeds its fair value. | We elected to early adopt this accounting standard update in the second quarter of 2017 on a prospective basis. | We expect the adoption of this update to simplify our annual goodwill impairment testing process, by eliminating the need to estimate the implied fair value of a reporting unit’s goodwill, if its respective carrying value exceeds fair value.

Standard/Description | Effective Date and Adoption Considerations | Effect on Financial Statements or Other Significant Matters
Financial Instruments - Recognition and Measurement. Requires changes to the accounting for financial instruments that primarily affect equity securities, financial liabilities measured using the fair value option, and the presentation and disclosure requirements for such instruments. | Effective in the first quarter of 2018. Changes to our marketable equity securities are required to be adopted using a modified-retrospective approach through a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. A cumulative-effect adjustment equal to the balance of unrealized gains or losses in accumulated other comprehensive income (loss) for these securities as of December 31, 2017 will be recorded to retained earnings in the period of adoption. Due to fluctuations in our portfolio, the precise impact from adopting the standard will not be known until December 31, 2017. Since management has elected to apply the measurement alternative to non-marketable equity securities, changes to these securities are adopted prospectively. | Marketable equity securities previously classified as available-for-sale equity investments will be measured and recorded at fair value with changes in fair value recorded through the income statement. All non-marketable equity securities formerly classified as cost method investments will be measured and recorded using the measurement alternative upon adoption. Equity securities measured and recorded using the measurement alternative are recorded at cost minus impairment, if any, plus or minus changes resulting from observable price changes. Adjustments resulting from impairments and observable price changes will be recorded in the income statement. Beginning in the first quarter of 2018, in accordance with the standard, fair value measurement and hierarchy disclosures will no longer be provided for equity securities measured using the measurement alternative. In addition, the existing impairment model will be replaced with a new one-step qualitative impairment model. No initial adoption adjustment will be recorded for these instruments since the standard is required to be applied prospectively for securities measured using the measurement alternative. We are finalizing our impact assessment and changes to our accounting policies and financial statement disclosures.
Compensation - Retirement Benefits - Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This amended standard was issued to provide additional guidance on the presentation of net benefit cost in the income statement and on the components eligible for capitalization in assets. The service cost component of the net periodic benefit cost will continue to be reported within operating income on the consolidated income statement. All other non-service components are required to be presented separately outside operating income and only service costs will be eligible for inventory capitalization. | Effective in the first quarter of 2018. Changes to the presentation of benefit costs are required to be adopted retrospectively while changes to the capitalization of service costs into inventories are required to be adopted prospectively. The standard permits, as a practical expedient, to use the amounts disclosed in the Retirement Benefit Plans footnote for the prior comparative periods as the estimation basis for applying the retrospective presentation requirement. | We expect the adoption of the amended standard to result in the reclassification of approximately $260 million from non-service components above the subtotal of operating income to interest and other, net, for the year ended December 31, 2016. We are continuing to assess the impacts of adoption to our 2017 financial statements.
