New Accounting Standards	NEW ACCOUNTING STANDARDS 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. Implementation Costs Incurred in a Cloud Computing Arrangement In August 2018, the FASB issued ASU 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract, which aligns the accounting for implementation costs incurred in a cloud computing arrangement that is a service contract with the guidance on capitalizing costs associated with developing or obtaining internal-use software. The guidance amends Accounting Standards Codification (ASC) 350 to include in its scope implementation costs of a cloud computing arrangement that is a service contract and clarifies that a customer should apply ASC 350 to determine which implementation costs should be capitalized in such a cloud computing arrangement. This guidance is effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2019, which is the first quarter of fiscal 2021 for Sysco, with early adoption permitted.
