Summary of Accounting Policies (Policies)	Jul. 02, 2016
Accounting Policies [Abstract]
Business and Consolidation	Business and Consolidation Sysco Corporation, acting through its subsidiaries and divisions (Sysco or the company), is engaged in the marketing and distribution of a wide range of food and related products primarily to the foodservice or food-away-from-home industry. These services are performed for approximately 425,000 customers from 199 distribution facilities located throughout the United States (U.S.), Bahamas, Canada and Ireland. Sysco’s fiscal year ends on the Saturday nearest to June 30^th. This resulted in a 53-week year ending July 2, 2016 for fiscal 2016, and 52-week years for the years ended June 27, 2015 for fiscal 2015 and June 28, 2014 for fiscal 2014. The accompanying financial statements include the accounts of Sysco and its consolidated subsidiaries. All significant intercompany transactions and account balances have been eliminated. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates that affect the reported amounts of assets, liabilities, sales and expenses. Actual results could differ from the estimates used.
Fiscal period	Sysco’s fiscal year ends on the Saturday nearest to June 30^th. This resulted in a 53-week year ending July 2, 2016 for fiscal 2016, and 52-week years for the years ended June 27, 2015 for fiscal 2015 and June 28, 2014 for fiscal 2014.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash includes cash equivalents such as time deposits, certificates of deposit, short-term investments and all highly liquid instruments with original maturities of three months or less, which are recorded at fair value.
Accounts Receivable	Accounts Receivable Accounts receivable consist primarily of trade receivables from customers and receivables from suppliers for marketing or incentive programs. Sysco determines the past due status of trade receivables based on contractual terms with each customer. Sysco evaluates the collectability of accounts receivable and determines the appropriate reserve for doubtful accounts based on a combination of factors. The company utilizes specific criteria to determine uncollectible receivables to be written off including whether a customer has filed for or been placed in bankruptcy, has had accounts referred to outside parties for collection or has had accounts past due over specified periods. In these instances, a specific allowance for doubtful accounts is recorded to reduce the receivable to the net amount reasonably expected to be collected. Allowances are recorded for all other receivables based on an analysis of historical trends of write-offs and recoveries.
Inventories	Inventories Inventories consisting primarily of finished goods include food and related products and lodging products held for resale and are valued at the lower of cost (first-in, first-out method) or market. Elements of costs include the purchase price of the product and freight charges to deliver the product to the company’s warehouses and are net of certain cash or non-cash consideration received from vendors (see “Vendor Consideration”).
Plant and Equipment	Plant and Equipment Capital additions, improvements and major replacements are classified as plant and equipment and are carried at cost. Depreciation is recorded using the straight-line method, which reduces the book value of each asset in equal amounts over its estimated useful life, and is included within operating expenses in the consolidated results of operations. Maintenance, repairs and minor replacements are charged to earnings when they are incurred. Upon the disposition of an asset, its accumulated depreciation is deducted from the original cost, and any gain or loss is reflected in current earnings. Certain internal and external costs related to the acquisition and development of internal use software are capitalized within plant and equipment during the application development stages of the project. Applicable interest charges incurred during the construction of new facilities and development of software for internal use are capitalized as one of the elements of cost and are amortized over the assets’ estimated useful lives.
Long-Lived Assets	Long-Lived Assets Management reviews long-lived assets for indicators of impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Cash flows expected to be generated by the related assets are estimated over the asset’s useful life based on updated projections on an undiscounted basis. For assets held for use, Sysco groups assets and liabilities at the lowest level for which cash flows are separately identifiable. If the evaluation indicates that the carrying value of the asset may not be recoverable, the potential impairment is measured using fair value. Impairment losses for assets to be disposed of, if any, are based on the estimated proceeds to be received, less costs of disposal.
Goodwill and Intangibles	Goodwill and Intangibles Goodwill and intangibles represent the excess of cost over the fair value of tangible net assets acquired. Goodwill and intangibles with indefinite lives are not amortized. Goodwill is assigned to the reporting units that are expected to benefit from the synergies of a business combination. The recoverability of goodwill and indefinite-lived intangibles is assessed annually, or more frequently as needed when events or changes have occurred that would suggest an impairment of carrying value, by determining whether the fair values of the applicable reporting units exceed their carrying values. The reporting units used to assess goodwill impairment are the company’s 14 operating segments as described in Note 22, “Business Segment Information.” The components within each of the 14 operating segments have similar economic characteristics and therefore are aggregated into 14 reporting units. The evaluation of fair value requires the use of projections, estimates and assumptions as to the future performance of the operations in performing a discounted cash flow analysis, as well as assumptions regarding sales and earnings multiples that would be applied in comparable acquisitions. Intangibles with definite lives are amortized over their useful lives in a manner consistent with underlying cash flow, which generally ranges from two to ten years. Management reviews finite-lived intangibles for indicators of impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Cash flows expected to be generated by the finite-lived intangibles are estimated over the intangible asset’s useful life based on updated projections on an undiscounted basis. If the evaluation indicates that the carrying value of the finite-lived intangible asset may not be recoverable, the potential impairment is measured at fair value.
Restricted Cash	Restricted Cash Sysco is required by its insurers to collateralize a part of the self-insured portion of its workers’ compensation and liability claims. Sysco has chosen to satisfy these collateral requirements by depositing funds in insurance trusts or by issuing letters of credit. Sysco chose to satisfy these collateral requirements by issuing letters of credit in fiscal 2016. All amounts in restricted cash at June 27, 2015 represented funds deposited in insurance trusts.
Derivative Financial Instruments	Derivative Financial Instruments All derivatives are recognized as assets or liabilities within the consolidated balance sheets at fair value at their gross values. Gains or losses on derivative financial instruments designated as fair value hedges are recognized immediately in the consolidated results of operations, along with the offsetting gain or loss related to the underlying hedged item. Gains or losses on derivative financial instruments designated as cash flow hedges are recorded as a separate component of shareholders’ equity from inception of the hedges to their settlement, at which time gains or losses are reclassified to the Consolidated Results of Operations in conjunction with the recognition of the underlying hedged item. In the normal course of business, Sysco enters into forward purchase agreements for the procurement of fuel and electricity. Certain of these agreements meet the definition of a derivative. However, the company elected to use the normal purchase and sale exemption available under derivatives accounting literature; therefore, these agreements are not recorded at fair value.
Investments in Corporate-Owned Life Insurance	Investments in Corporate-Owned Life Insurance Investments in corporate-owned life insurance (COLI) policies are recorded at their cash surrender values as of each balance sheet date. Changes in the cash surrender value during the period are recorded as a gain or loss within operating expenses. Sysco has the ability and intent to hold its COLI policies to maturity and the company does not record deferred tax balances related to cash surrender value gains or losses for these policies. Deferred tax balances are recorded for those policies that Sysco intends to redeem prior to maturity.
Treasury Stock	Treasury Stock The company records treasury stock purchases at cost. Shares removed from treasury are valued at cost using the average cost method.
Foreign Currency Translation	Foreign Currency Translation The assets and liabilities of all foreign subsidiaries are translated at current exchange rates. Related translation adjustments are recorded as a component of accumulated other comprehensive income (loss).
Revenue Recognition	Revenue Recognition The company recognizes revenue from the sale of a product when it is considered to be realized or realizable and earned. The company determines these requirements to be met at the point at which the product is delivered to the customer. The company grants certain customers sales incentives such as rebates or discounts and treats these as a reduction of sales at the time the sale is recognized. Sales tax collected from customers is not included in revenue but rather recorded as a liability due to the respective taxing authorities. Purchases and sales of inventory with the same counterparty that are entered into in contemplation of one another are considered to be a single nonmonetary transaction. As such, the company records the net effect of such transactions in the consolidated results of operations within sales.
Vendor Consideration	Vendor Consideration Sysco recognizes consideration received from vendors when the services performed in connection with the monies received are completed and when the related product has been sold by Sysco as a reduction to cost of sales. There are several types of cash consideration received from vendors. In many instances, the vendor consideration is in the form of a specified amount per case or per pound. In these instances, Sysco will recognize the vendor consideration as a reduction of cost of sales when the product is sold. In the situations in which the vendor consideration is not related directly to specific product purchases, Sysco will recognize these as a reduction of cost of sales when the earnings process is complete, the related service is performed and the amounts are realized.
Shipping and Handling Costs	Shipping and Handling Costs Shipping and handling costs include costs associated with the selection of products and delivery to customers.
Insurance Program	Insurance Program Sysco maintains a self-insurance program covering portions of workers’ compensation, general and vehicle liability and property insurance costs. The amounts in excess of the self-insured levels are fully insured by third party insurers. The company also maintains a fully self-insured group medical program. Liabilities associated with these risks are estimated in part by considering historical claims experience, medical cost trends, demographic factors, severity factors and other actuarial assumptions.
Share-Based Compensation	Share-Based Compensation Sysco recognizes expense for its share-based compensation based on the fair value of the awards that are granted. The fair value of stock options is estimated at the date of grant using the Black-Scholes option pricing model. Option pricing methods require the input of highly subjective assumptions, including the expected stock price volatility. The fair value of restricted stock and restricted stock unit awards are based on the company’s stock price on the date of grant. Measured compensation cost is recognized ratably over the vesting period of the related share-based compensation award. Cash flows resulting from tax deductions in excess of the compensation cost recognized for those options (excess tax benefits) are classified as financing cash flows on the consolidated cash flows statements.
Income Taxes	Income Taxes Sysco recognizes deferred tax assets and liabilities based on the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured pursuant to tax laws using rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The impact on deferred tax assets and liabilities of a change in tax rate is recognized in income in the period that includes the enactment date. Valuation allowances are established when necessary to reduce deferred tax assets to the amount more likely than not to be realized. Sysco recognizes a tax benefit from an uncertain tax position when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits of the position. The amount recognized is measured as the largest amount of tax benefit that has greater than a 50% likelihood of being realized upon settlement. To the extent interest and penalties may be assessed by taxing authorities on any underpayment of income tax, estimated amounts required by the accounting guidance related to uncertain tax positions have been accrued and are classified as a component of income taxes in the consolidated results of operations. The determination of the company’s provision for income taxes requires significant judgment, the use of estimates and the interpretation and application of complex tax laws. The company’s provision for income taxes primarily reflects a combination of income earned and taxed in the various U.S. federal and state, as well as various foreign jurisdictions. Jurisdictional tax law changes, increases or decreases in permanent differences between book and tax items, accruals or adjustments of accruals for tax contingencies or valuation allowances, and the company’s change in the mix of earnings from these taxing jurisdictions all affect the overall effective tax rate.
Acquisitions	Acquisitions Acquisitions of businesses are accounted for using the acquisition method of accounting, and the financial statements include the results of the acquired operations from the respective dates of acquisition. The purchase price of the acquired entities is allocated to the net assets acquired and liabilities assumed based on the estimated fair value at the dates of acquisition, with any excess of cost over the fair value of net assets acquired, including intangibles, recognized as goodwill. The balances included in the consolidated balance sheets related to recent acquisitions are based upon preliminary information and are subject to change when final asset and liability valuations are obtained. Subsequent changes to the preliminary balances are reflected retrospectively, if material. Material changes to the preliminary allocations are not anticipated by management.
Basis of Presentation	Basis of Presentation The financial statements include consolidated balance sheets, consolidated results of operations, consolidated statements of comprehensive income and consolidated cash flows. In the opinion of management, all adjustments, which consist of normal recurring adjustments, except as otherwise disclosed, necessary to present fairly the financial position, results of operations, comprehensive income and cash flows for all periods presented have been made. Deferred taxes within the consolidated balance sheet for July 2, 2016, have been classified as long-term due to the adoption of an accounting pronouncement related to simplification in the presentation of deferred taxes. See Note 2, "Changes in Accounting" for additional information on these changes. In fiscal 2015, Sysco acquired a 50% interest in a foodservice company in Mexico and accounted for this interest using the equity-method of accounting. In fiscal 2016, Sysco obtained control of the board of this company and began consolidating these operations; therefore, the financial position, results of operations and cash flows for this company have been included in Sysco’s consolidated financial statements. The value of the 50% noncontrolling interest is considered redeemable due to certain features of the investment agreement and has been presented as mezzanine equity, which is outside of permanent equity, in the consolidated balance sheets. The income attributable to the noncontrolling interest is located within Other expense (income), net, in the consolidated results of operations, as this amount is not material. The non-cash add back for the change in the value of the noncontrolling interest is located within Other non-cash items on the consolidated cash flows. In fiscal 2015, Sysco acquired a 50% interest in a foodservice company in Costa Rica. It was determined that consolidation of the entity was appropriate and, therefore, the financial position, results of operations and cash flows for this company have been included in Sysco’s consolidated financial statements. The value of the 50% noncontrolling interest is considered redeemable due to certain features of the investment agreement and has been presented as mezzanine equity, which is outside of permanent equity, in the consolidated balance sheets. The income attributable to the noncontrolling interest is located within Other expense (income), net in the consolidated results of operations, as this amount is not material. The non-cash add back for the change in the value of the noncontrolling interest is located within Other non-cash items on the consolidated cash flows.
New Accounting Pronouncements	Simplification of Balance Sheet Classification of Deferred Taxes In November 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2015-17, Balance Sheet Classification of Deferred Taxes, as part of its simplification initiative, which is the FASB's effort to reduce the cost and complexity of certain aspects of U.S. GAAP. This guidance requires that all deferred tax assets and liabilities, along with any related valuation allowance, be classified as non-current on the balance sheet. The guidance does not change the existing requirement that only permits offsetting of deferred tax assets and deferred tax liabilities within a jurisdiction. The company early adopted this standard in the second quarter of fiscal 2016 on a prospective basis, as permitted by the ASU. Stock Compensation In March 2016, the FASB issued ASU 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, as part of its initiative to reduce complexity in accounting standards. The areas for simplification involve several aspects of the accounting for employee share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. In addition, the amendments eliminate the guidance in Topic 718 that was indefinitely deferred shortly after the issuance of FASB Statement No. 123 (revised 2004), Share-Based Payment. The guidance is effective for interim and annual periods beginning after December 15, 2016, which is fiscal 2018 for Sysco, with early adoption permitted. The company is currently reviewing the provisions of the new standard. 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. Lessees and lessors will 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. Financial Instruments In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10), which requires the following: (1) all equity investments to be measured at fair value with changes in the fair value recognized through net income (other than those accounted for under equity method of accounting or those that result in consolidation of the investee); (2) an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments; and (3) eliminates the requirement to disclose the fair value of financial instruments measured at amortized cost for entities that are not public business entities and the requirement to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet for public business entities. The guidance is effective for interim and annual periods beginning after December 15, 2017, which is fiscal 2019 for Sysco. The company is currently reviewing the provisions of the new standard. Business Combinations In September 2015, the FASB issued ASU 2015-16, Business Combinations (Topic 805), which requires that an acquirer retrospectively adjust provisional amounts recognized in a business combination during the measurement period. To simplify the accounting for adjustments made to provisional amounts, the amendments require that the acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amount is determined. The acquirer is required to also record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. In addition, an entity is required to present separately on the face of the income statement or disclose in the notes to the financial statements the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015, which is fiscal 2017 for Sysco. The amendment will be applied prospectively to adjustments to provisional amounts that occur after the effective date with earlier adoption permitted. Revenue from Contracts with Customers In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). This new standard will replace all current GAAP 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. In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net), which clarifies the implementation guidance on principal versus agent considerations. The collective guidance is effective for interim and annual periods 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. The company has not selected a transition method and is currently evaluating the impact of the pending adoption of this ASU on its ongoing financial reporting.
