Accounting Changes and Error Corrections [Abstract]
Changes in Accounting	CHANGES IN ACCOUNTING Stock Compensation In March 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-09, Improvements to Employee Share-Based Payment Accounting (Topic 718). The ASU identifies areas for simplification involving several aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as equity or liabilities, an option to recognize gross stock compensation expense with actual forfeitures recognized as they occur, as well as certain classifications on the statement of cash flows. The company elected to maintain the current policy to estimate forfeitures expected to occur to determine stock-based compensation expense. Further, the company adopted the provisions that have changed its accounting for excess tax benefits, or detriments. Excess tax benefits, or detriments, were previously included within additional paid-in capital in the consolidated balance sheet and were a part of the diluted share calculation. With the adoption of ASU 2016-09 on a prospective basis, excess tax benefits, or detriments, are included within income tax expense in the consolidated results of operations and are no longer a part of the diluted share calculation. In the first quarter of fiscal 2018, the company recognized excess tax benefits of $16.0 million from stock option exercises that occurred during the quarter. The standard also requires several presentation changes with regard to the statement of cash flows. Cash flows related to excess tax benefits or detriments are included in net cash provided by operating activities, rather than as a financing activity. Sysco chose a retrospective application of this provision; therefore, amounts presented for fiscal 2017 reflect the guidance required by this ASU. The standard further requires that cash paid by an employer, when directly withholding shares for tax withholding purposes, should be classified as a financing activity. Retrospective application is required for this provision; however, amounts were not material for either period and, therefore, were not separately disclosed or retroactively applied. Simplifying the Test for Goodwill Impairment In January 2017, the FASB issued ASU 2017-04, Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, which simplifies the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. The amendments also eliminate the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The company elected to early adopt this ASU, as it is easier to execute.
