New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements	Adoption of New Accounting Pronouncements Goodwill Impairment In January 2017, the FASB issued authoritative guidance intended to simplify the subsequent measurement of goodwill by eliminating step two from the goodwill impairment test. Under the new guidance, the recognition of an impairment charge is calculated based on the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The guidance should be applied on a prospective basis and is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. We early adopted this guidance during the quarter ended March 31, 2017. New Accounting Pronouncements Not Yet Adopted Financial and Commodity Risks In August 2017, the FASB issued authoritative guidance intended to refine and expand hedge accounting for both financial and commodity risks. The revised guidance will create more transparency around how economic results are presented, both on the face of the financial statements and in the footnotes. In addition, this guidance makes certain targeted improvements to simplify the application of hedge accounting guidance. This guidance is effective for annual periods beginning after December 15, 2018, including interim periods within those annual periods, with early adoption permitted. We are currently evaluating the potential impact on our financial position and results of operations upon adoption of this guidance. Pension and Other Postretirement Benefit Plans In March 2017, the FASB issued authoritative guidance intended to improve the consistency, transparency and usefulness of financial information related to defined benefit pension or other postretirement plans. Under the new guidance, an employer must disaggregate the service cost component from the other components of net benefit cost within the income statement. Specifically, the new guidance will require us only to report the service cost component in the same line item as other compensation costs arising from services rendered by the pertinent employees during the period; while the other components of net benefit cost will now be presented in the income statement separately from the service cost component and outside of operating income. The amendments in this update also allow only the service cost component to be eligible for capitalization when applicable. This guidance is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods. The guidance related to the income statement presentation of service costs and other pension and postretirement benefit costs should be applied retrospectively, while the capitalization of service costs component should be applied prospectively. These changes will impact the presentation of net periodic pension costs and net periodic postretirement benefit costs within our results of operations upon adoption of this guidance. We currently anticipate the impact of this guidance for the year ended December 31, 2017, based on financial information retrospectively adjusted for the pension methodology change as discussed in Note 1, "Basis of Presentation and Summary of Significant Accounting Policies", to be an increase to cost of goods sold of approximately $19 million, an increase to marketing, general and administrative expense of $20 million, and an increase to expense recorded within special items, net of approximately $8 million, and an offsetting benefit to other income (expense), net of approximately $47 million. In conjunction with the adoption of this guidance, we will also retrospectively and prospectively allocate the non-service component of pension and other postretirement benefit plan cost to our Corporate segment. Accordingly, only service cost will be recorded in our segments' results of operations going forward. We anticipate the impact of this reclassification to be a benefit, recorded within other income (expense), net of approximately $47 million within our Corporate segment for the year ended December 31, 2017, with an offsetting impact to cost of goods sold (increase to our Europe segment of approximately $27 million and decrease to our U.S. segment and Canada segment of approximately $7 million and $1 million, respectively), marketing, general and administrative expenses (increase to our Europe segment of approximately $19 million, as well as increases to each of our Canada and U.S. segments of approximately $0.5 million) and special items, net (increase to our U.S. and Canada segments of approximately $5 million and $3 million, respectively). Leases In February 2016, the FASB issued authoritative guidance intended to increase transparency and comparability among organizations by recognizing lease assets and liabilities on the balance sheet and disclosing key information about leasing arrangements. Under the new guidance, lessees will be required to recognize a right-of-use asset and a lease liability, measured on a discounted basis, at the commencement date for all leases with terms greater than twelve months. Additionally, this guidance will require disclosures to help investors and other financial statement users to better understand the amount, timing, and uncertainty of cash flows arising from leases, including qualitative and quantitative requirements. The guidance should be applied under a modified retrospective transition approach. This guidance is effective for annual reporting periods beginning after December 15, 2018, including interim periods within those annual periods, with early adoption permitted. We are currently evaluating the potential impact on our financial position and results of operations upon adoption of this guidance. This guidance will result in our existing operating leases, for certain real estate and equipment, to be recognized on our balance sheet. We will further analyze our lease arrangements as we complete our assessment and implementation of this new guidance. Revenue Recognition In May 2014, the FASB issued authoritative guidance related to new accounting requirements for the recognition of revenue from contracts with customers. 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 to in exchange for the goods or services. We will adopt this guidance and related amendments as of January 1, 2018, applying the modified retrospective transition approach to all contracts. Based on our comprehensive assessment of the new guidance, including our evaluation of the five-step approach outlined within the guidance, we concluded that the adoption will not have a significant impact to our core revenue generating activities. However, the adoption will result in a change in presentation of certain cash payments made to customers as well as the timing of recognition of certain promotional discounts. Specifically, certain cash payments to customers were previously recorded within marketing, general and administrative expenses in the consolidated statements of operations. Upon the adoption of the new guidance, many of these cash payments will not meet the specific criteria within the new guidance of providing a “distinct” good or service, and therefore, will be required to be presented as a reduction of revenue. Based on foreign exchange rates as of December 31, 2017, we currently anticipate that the impact of this change will result in a reduction of revenue and marketing, general and administrative expenses by approximately $70 million to $90 million during the first year of adoption, primarily within our Canada segment, with no impact to net income. However, actual results may differ from these estimates. Furthermore, upon adoption of the new guidance, certain of our promotional discounts which are deemed variable consideration under the new guidance, will now be recognized at the time of the related shipment of product, which is earlier than recognized under historical guidance. We anticipate that this change in recognition timing will shift financial statement recognition primarily amongst quarters, however, do not anticipate that the full-year impact will be significant to our financial results. We also evaluated the requirements of the new guidance on our other revenue generating activities such as contract brewing and license arrangements, and concluded that no changes to our historical accounting treatment is required. As a result of the cumulative impact of adopting the new guidance in the first quarter of 2018, we currently expect to record a net reduction to opening retained earnings of approximately $26 million to $30 million as of January 1, 2018, with an offsetting increase primarily within accounts payable and other current liabilities, and the related tax effects, related primarily to the accelerated recognition of certain promotional discounts. We are in the process of finalizing this transition adjustment calculation, which will be completed during the first quarter of 2018. Other than the items noted above, there have been no new accounting pronouncements not yet effective or adopted in the current year that we believe have a significant impact, or potential significant impact, to our consolidated financial statements.
