Recently Adopted Accounting Standards	Recently Adopted Accounting Standards In July 2015, amended accounting guidance was issued regarding the measurement of inventory. The amended guidance requires that inventory accounted for under the first-in, first-out (FIFO) or average cost methods be measured at the lower of cost and net realizable value, where net realizable value represents the estimated selling price of inventory in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The amended guidance has no impact on inventory accounted for under the last-in, first-out (LIFO) or retail inventory methods. The Company adopted this amended guidance on a prospective basis effective June 1, 2017. The adoption of this guidance did not impact our consolidated financial position or results of operations.
Recently Issued Accounting Standards	Recently Issued Accounting Standards In May 2014, new accounting guidance was issued that replaces most existing revenue recognition guidance under U.S. GAAP. The new guidance requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. Subsequently, additional guidance was issued on several areas including guidance intended to improve the operability and understandability of the implementation of principal versus agent considerations and clarifications on the identification of performance obligations and implementation of guidance related to licensing. The new guidance is effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. The guidance permits the use of either the retrospective or cumulative effect transition method. We are in the process of evaluating the effect this guidance will have on the presentation of our consolidated financial statements and related disclosures. While we have not yet identified any material changes in the timing of revenue recognition, our evaluation is ongoing and not complete. We plan to adopt the new guidance in the first quarter of fiscal 2019. The Company will continue to monitor any modifications, clarifications, and interpretations by the FASB that may impact its conclusions. In February 2016, new accounting guidance was issued that replaces most existing lease accounting guidance under U.S. GAAP. Among other changes, the new guidance requires that lease assets and liabilities be recognized on the balance sheet by lessees for those leases classified as operating leases under previous guidance. The new guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted, and the change is to be applied using a modified retrospective approach as of the beginning of the earliest period presented. We are in the process of evaluating the effect this guidance will have on our consolidated financial position, results of operations and cash flows, and we have not determined the effect of the new guidance on our ongoing financial reporting. In June 2016, new accounting guidance was issued related to the measurement of credit losses on financial instruments. The new guidance changes the impairment model for most financial assets to require measurement and recognition of expected credit losses for financial assets held. The new guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. We are in the process of evaluating the effect this guidance will have on our consolidated financial position and results of operations, and we have not determined the effect of the new guidance on our ongoing financial reporting. In August 2016, amended accounting guidance was issued to clarify the proper cash flow presentation of certain specific types of cash payments and cash receipts. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We are in the process of evaluating the effect this guidance will have on our consolidated financial position, results of operations and cash flows, and we have not determined the effect of the amended guidance on our ongoing financial reporting. In October 2016, amended accounting guidance was issued that requires the income tax consequences of an intra-entity transfer of an asset other than inventory to be recognized when the transfer occurs. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We are in the process of evaluating the effect this guidance will have on our consolidated financial position, results of operations and cash flows, and have not determined the effect of the amended guidance on our ongoing financial reporting. In November 2016, amended accounting guidance was issued that requires amounts generally described as restricted cash and restricted cash equivalents to be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We do not expect the adoption of this amended guidance to have a material impact on our consolidated cash flows. In January 2017, amended accounting guidance was issued to clarify the definition of a business to provide additional guidance to assist in evaluating whether transactions should be accounted for as an acquisition (or disposal) of either an asset or business. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We do not expect the adoption of this amended guidance to have a material impact on our consolidated financial position or results of operations. In January 2017, amended accounting guidance was issued to simplify the goodwill impairment calculation, by removing Step 2 of the goodwill impairment test. Goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of the goodwill. The amended guidance is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. We are in the process of evaluating the effect this guidance will have on our consolidated financial position and results of operations, and have not determined the effect on our ongoing financial reporting. In March 2017, amended accounting guidance was issued that requires an employer to report the service cost component of pension and postretirement benefits in the same line as other current employee compensation costs. Additionally, other components of net benefit cost are to be presented in the income statement separately from the service cost component and outside of income from operations. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. We are in the process of evaluating the effect this guidance will have on our consolidated financial position and results of operations, and have not determined the effect on our ongoing financial reporting. In May 2017, amended accounting guidance was issued to provide guidance about which changes to the terms or conditions of a share-based payment award require application of modification accounting. The amended guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. We do not expect the adoption of this amended guidance to have a material impact on our consolidated financial position or results of operations. In August 2017, amended accounting guidance was issued that modifies hedge accounting by making more hedge strategies eligible for hedge accounting, amending presentation and disclosure requirements, and changing how companies assess effectiveness. The intent is to simplify application of hedge accounting and increase transparency of information about an entity’s risk management activities. The amended guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. We are in the process of evaluating the effect this guidance will have on our consolidated financial position and results of operations, and have not determined the effect on our ongoing financial reporting.
Economic (Non-designated) Hedges	Economic (Non-designated) Hedges We enter into foreign currency exchange contracts to manage our foreign currency exchange rate exposure related to inter-company and financing transactions that do not meet the requirements for hedge accounting treatment. We also enter into certain commodity contracts that do not qualify for hedge accounting treatment. Accordingly, these derivative instruments are adjusted to current market value at the end of each period through earnings.
Cash Flow Hedges
Cash Flow Hedges	Cash Flow Hedges We enter into derivative instruments to hedge our exposure to changes in cash flows attributable to interest rate and commodity price fluctuations associated with certain forecasted transactions. These derivative instruments are designated and qualify as cash flow hedges. Accordingly, the effective portion of the gain or loss on the derivative instrument is reported as a component of OCI and reclassified into earnings in the same line associated with the forecasted transaction and in the same period during which the hedged transaction affects earnings. The ineffective portion of the gain or loss on the derivative instrument is recognized in earnings immediately.
