Subsequent Events [Abstract]
Subsequent Events	SUBSEQUENT EVENTS In May 2017, a Sysco subsidiary voluntarily withdrew from a multiemployer pension plan and has recorded a $35.6 million withdrawal liability subsequent to the third quarter of fiscal 2017. This withdrawal liability was estimated at the time of withdrawal based on the most recently available valuation and participant data for the plan and amounts could be subsequently adjusted to the period of payment to reflect any changes to this estimate. If this plan were to undergo a mass withdrawal, as defined by the Pension Benefit Guaranty Corporation, within the two plan years following the plan year in which we withdrew from that plan, Sysco could have additional liability. The May 2017 withdrawal was not pursuant to an agreement or arrangement with any other entity. Potential Withdrawal Liability Under current law regarding multiemployer defined benefit plans, a plan’s termination, Sysco’s voluntary withdrawal, or the mass withdrawal of all contributing employers from any underfunded multiemployer defined benefit plan would require Sysco to make payments to the plan for Sysco’s proportionate share of the multiemployer plan’s unfunded vested liabilities. Generally, Sysco does not have the greatest share of potential withdrawal liability among the contributing employers in any of the multiemployer pension plans to which it contributes. Sysco believes that one of the above-mentioned events is reasonably possible for certain plans in which it participates; however, the company estimates its share of withdrawal liability for these plans is not significant. This estimate excludes plans for which Sysco has recorded a withdrawal liability or where the likelihood of the above-mentioned events is deemed remote. This estimate is based on the information available from plan administrators, which had valuation dates ranging from December 31, 2013 to January 1, 2015, with January 1, 2015 being the date for a majority of the plans. The company’s estimate reflects the condition of each applicable multiemployer pension plan as of those dates. Due to the lack of current information, management believes Sysco’s share of any potential withdrawal liability at the time of a withdrawal event could materially differ from this estimate.
