New Accounting Standards	NEW ACCOUNTING STANDARDS Revenue from Contracts with Customers In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), and has issued subsequent amendments to this guidance. This new standard will replace all current guidance on this topic and eliminate all industry-specific guidance. The new revenue recognition standard provides a unified model to determine when and how revenue is recognized. The core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services. The guidance is effective for interim and annual periods within new fiscal years beginning after December 15, 2017, which is fiscal 2019 for Sysco, and could be early adopted in fiscal 2018. The standard may be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. As of the end of the second quarter of fiscal 2018, the company was nearing the completion of its assessment of the accounting required under Topic 606 and is completing its documentation of these conclusions. Based on the work completed to date, Sysco does not expect that the implementation of the new standard will have a material effect on the company’s financial statements. The company will continue its assessment and will adopt the standard in the first quarter of fiscal 2019 and expects to use the modified retrospective method. Enhanced disclosures, including revenue recognition policies to identify performance obligations to customers and significant judgments in measurement and recognition, are required. Leases In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), specifying the accounting for leases, which supersedes the leases requirements in Topic 840, Leases. The objective of Topic 842 is to establish the principles that lessees and lessors shall apply to report useful information to users of financial statements about the amount, timing, and uncertainty of cash flows arising from a lease. Lessees are permitted to make an accounting policy election to not recognize the asset and liability for leases with a term of twelve months or less. Lessors’ accounting is largely unchanged from the previous accounting standard. In addition, Topic 842 expands the disclosure requirements of lease arrangements. Topic 842 currently requires lessees and lessors to use a modified retrospective transition approach, which includes a number of practical expedients. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, which is fiscal 2020 for Sysco, with early adoption permitted. The company is currently reviewing the provisions of the new standard.

Revenue from Contracts with Customers

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), and has issued subsequent amendments to this guidance. This new standard will replace all current guidance on this topic and eliminate all industry-specific guidance. The new revenue recognition standard provides a unified model to determine when and how revenue is recognized. The core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services.
