Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES Tax Cuts and Jobs Act On December 22, 2017, the U.S. government enacted the Tax Act. The Tax Act makes broad and complex changes to the U.S. tax code that will affect the company’s fiscal year ending June 30, 2018, including, but not limited to: (1) reducing the U.S. federal corporate tax rate; (2) requiring a one-time transition tax on certain unrepatriated earnings of foreign subsidiaries that is payable over 8 years; and (3) bonus depreciation that will allow for full expensing of qualified property placed in service after September 27, 2017. The Tax Act also establishes new tax laws that could affect Sysco in future fiscal years, including, but not limited to (1) a general elimination of U.S. federal income taxes on dividends from foreign subsidiaries; (2) a new provision designed to tax global intangible low-taxed income (GILTI); (3) creation of the base erosion anti-abuse tax (BEAT), a new minimum tax; (4) a new limitation on deductible interest; (5) repeal of the domestic production activity deduction; and (6) increased limitations on the deductibility of certain executive compensation. The SEC staff issued SAB 118, which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under Accounting Standards Codification Topic 740, “Income Taxes” (ASC 740). In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete, but it is able to determine a reasonable estimate, it must record a provisional estimate in its financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act. For various reasons that are discussed in greater detail below, the company has not completed its accounting for the income tax effects of certain elements of the Tax Act. In cases where Sysco was able to make reasonable estimates of the effects of elements for which its analysis is not yet complete, the company recorded provisional adjustments. If Sysco was not yet able to make reasonable estimates of the impact of certain elements, the company has not recorded any adjustments related to those elements and has continued accounting for them in accordance with ASC 740 on the basis of the tax laws in effect before the Tax Act. Our accounting for the following elements of the Tax Act is incomplete. However, the company was able to make reasonable estimates of certain effects and, therefore, recorded provisional adjustments of $35.8 million, which is our initial estimate of the following impacts of the Tax Act: Reduction of U.S. federal corporate tax rate: As a result of enactment of the Tax Act, the company revised its estimated annual effective tax rate to reflect a change in the U.S. statutory tax rate. As noted above, the Tax Act reduces the U.S. federal corporate tax rate to 21% in our fiscal year; however, Section 15 of the Internal Revenue Code stipulates that the reduction in the corporate tax rate is applied to fiscal year taxpayers by computing a blended tax rate, based on the applicable tax rates before and after the effective date of the change in the statutory rate. When applied to Sysco’s fiscal year, this blended rate is estimated as 28% for fiscal 2018, a benefit of $64.7 million due to the retroactive application of this lower rate to the beginning of the company’s fiscal year. In addition, the company has recorded a provisional tax benefit of $14.5 million attributable to remeasuring Sysco’s accrued income taxes, deferred tax liabilities and deferred tax assets. Transition Tax: The company recorded a discrete tax expense of $115.0 million attributable to the provisional impact of the transition tax. The transition tax is payable in eight annual installments beginning in our first quarter of fiscal 2019. As a result of the 8 year payment period, approximately $95.0 million attributable to the portion of the provisional transition tax not due within 12 months is located within other long-term liabilities in the consolidated balance sheet as of December 30, 2017. Our accounting for the following elements of the Tax Act is incomplete, and we were not able to make reasonable estimates of the effects. Therefore, no provisional adjustments were recorded. GILTI: The Tax Act creates a new requirement that certain income earned by controlled foreign corporations (CFCs) must be included currently in the gross income of the CFCs’ U.S. shareholder. GILTI is the excess of the shareholder’s “net CFC tested income” over the net deemed tangible income return, which is currently defined as the excess of (1) 10 percent of the aggregate of the U.S. shareholder’s pro rata share of the qualified business asset investment of each CFC with respect to which it is a U.S. shareholder over (2) the amount of certain interest expense taken into account in the determination of net CFC-tested income. Sysco will not be subject to the GILTI provisions until fiscal 2019. Because of the complexity of the new GILTI tax rules, the company is continuing to evaluate this provision of the Tax Act and the application of ASC 740. Under U.S. GAAP, the company is allowed to make an accounting policy choice of either (1) treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current-period expense when incurred (the “period cost method”) or (2) factoring such amounts into a company’s measurement of its deferred taxes (the “deferred method”). Sysco’s selection of an accounting policy with respect to the new GILTI tax rules will depend, in part, on analyzing our global income to determine whether the company expects to have future U.S. inclusions in taxable income related to GILTI and, if so, what the impact is expected to be. Because whether Sysco expects to have future U.S. inclusions in taxable income related to GILTI depends not only on our current structure and estimated future results of global operations but also the company’s intent and ability to modify its structure and/or its business, Sysco is not yet able to reasonably estimate the effect of this provision of the Tax Act. Therefore, the company has not made any adjustments related to potential GILTI tax in its financial statements and has not made a policy decision regarding whether to record deferred taxes on GILTI. Executive Compensation Limitation: The Tax Act expands the definition under Section 162(m) of the Internal Revenue Code (“Section 162(m)”) of covered employee and provides that, for specified employees, status as a covered employee continues for all subsequent tax years, including years after the death of the individual, and, among other modifications, repeals the exception for performance-based compensation and commissions from the $1 million deduction limitation. In addition, the Tax Act provides for transitional guidance that will allow certain payments made under written and binding agreements entered into prior to November 2, 2017 to be treated as if they were made under the provisions of Section 162(m) that were in effect prior to enactment of the Tax Act. The company is in the process of gathering information on existing compensation arrangements for covered employees as well as assessing the impact of transitional guidance on the realizability of existing deferred tax assets related to compensation arrangements of its covered employees. As a result, the company has not made any adjustments related to impacts of the new executive compensation limitations in its financial statements. Indefinite Reinvestment Assertion: The company is in the process of assessing the impact of the Tax Act on its indefinite reinvestment assertion and the company’s plans to determine any associated impact on the financial statements. Therefore, no adjustments have been made in its financial statements with respect to its indefinite reinvestment assertion. Effective Tax Rate Sysco’s effective tax rate is reflective of the jurisdictions where the company has operations. The effective tax rates for the second quarter and first 26 weeks of fiscal 2018 were 37.11% and 34.71%, respectively. The effective tax rates for the second quarter and first 26 weeks of fiscal 2018 were negatively impacted by the transition tax described above resulting from the Tax Act. These effective tax rates were impacted favorably by a net tax benefit of $79.2 million attributable to the change in the federal statutory tax rate described above, along with the impact of tax law changes in certain foreign jurisdictions and excess tax benefits of equity-based compensation that totaled $8.1 million and $14.8 million, respectively. Sysco began recognizing these excess tax benefits within income tax expense in the first quarter of fiscal 2018 due to the adoption of ASU 2016-09. The effective tax rate for the second quarter of fiscal 2017 of 34.87% and the first 26 weeks of fiscal 2017 of 35.09% was favorably impacted by an increase in earnings in foreign jurisdictions due to the acquisition of the Brakes Group. Uncertain Tax Positions As of December 30, 2017, the gross amount of unrecognized tax benefit and related accrued interest was $16.2 million and $11.5 million, respectively. It is reasonably possible that the amount of the unrecognized tax benefit with respect to certain of the company’s unrecognized tax positions will increase or decrease in the next twelve months, either because Sysco prevails on positions challenged upon audit or because the company agrees to the disallowance. Items that may cause changes to unrecognized tax benefits primarily include the consideration of various filing requirements in numerous states and the allocation of income and expense between tax jurisdictions. At this time, an estimate of the range of the reasonably possible change cannot be made. Other The determination of the company’s provision for income taxes requires judgment, the use of estimates and the interpretation and application of complex tax laws. The company’s provision for income taxes reflects a combination of income earned and taxed in the various U.S. federal and state, as well as foreign, jurisdictions. Jurisdictional tax law changes, increases or decreases in permanent differences between book and tax items, accruals or adjustments of accruals for unrecognized tax benefits or valuation allowances, and the company’s change in the mix of earnings from these taxing jurisdictions all affect the overall effective tax rate.

INCOME TAXES

Tax Cuts and Jobs Act

On December 22, 2017, the U.S. government enacted the Tax Act. The Tax Act makes broad and complex changes to the U.S. tax code that will affect the company’s fiscal year ending June 30, 2018, including, but not limited to: (1) reducing the U.S. federal corporate tax rate; (2) requiring a one-time transition tax on certain unrepatriated earnings of foreign subsidiaries that is payable over 8 years; and (3) bonus depreciation that will allow for full expensing of qualified property placed in service after September 27, 2017. The Tax Act also establishes new tax laws that could affect Sysco in future fiscal years, including, but not limited to (1) a general elimination of U.S. federal income taxes on dividends from foreign subsidiaries; (2) a new provision designed to tax global intangible low-taxed income (GILTI); (3) creation of the base erosion anti-abuse tax (BEAT), a new minimum tax; (4) a new limitation on deductible interest; (5) repeal of the domestic production activity deduction; and (6) increased limitations on the deductibility of certain executive compensation.

The SEC staff issued SAB 118, which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under Accounting Standards Codification Topic 740, “Income Taxes” (ASC 740). In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete, but it is able to determine a reasonable estimate, it must record a provisional estimate in its financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act. For various reasons that are discussed in greater detail below, the company has not completed its accounting for the income tax effects of certain elements of the Tax Act. In cases where Sysco was able to make reasonable estimates of the effects of elements for which its analysis is not yet complete, the company recorded provisional adjustments. If Sysco was not yet able to make reasonable estimates of the impact of certain elements, the company has not recorded any adjustments related to those elements and has continued accounting for them in accordance with ASC 740 on the basis of the tax laws in effect before the Tax Act.

Our accounting for the following elements of the Tax Act is incomplete. However, the company was able to make reasonable estimates of certain effects and, therefore, recorded provisional adjustments of $35.8 million, which is our initial estimate of the following impacts of the Tax Act:

Reduction of U.S. federal corporate tax rate: As a result of enactment of the Tax Act, the company revised its estimated annual effective tax rate to reflect a change in the U.S. statutory tax rate. As noted above, the Tax Act reduces the U.S. federal corporate tax rate to 21% in our fiscal year; however, Section 15 of the Internal Revenue Code stipulates that the reduction in the corporate tax rate is applied to fiscal year taxpayers by computing a blended tax rate, based on the applicable tax rates before and after the effective date of the change in the statutory rate. When applied to Sysco’s fiscal year, this blended rate is estimated as 28% for fiscal 2018, a benefit of $64.7 million due to the retroactive application of this lower rate to the beginning of the company’s fiscal year. In addition, the company has recorded a provisional tax benefit of $14.5 million attributable to remeasuring Sysco’s accrued income taxes, deferred tax liabilities and deferred tax assets.

Transition Tax: The company recorded a discrete tax expense of $115.0 million attributable to the provisional impact of the transition tax. The transition tax is payable in eight annual installments beginning in our first quarter of fiscal 2019. As a result of the 8 year payment period, approximately $95.0 million attributable to the portion of the provisional transition tax not due within 12 months is located within other long-term liabilities in the consolidated balance sheet as of December 30, 2017.

Our accounting for the following elements of the Tax Act is incomplete, and we were not able to make reasonable estimates of the effects. Therefore, no provisional adjustments were recorded.

GILTI: The Tax Act creates a new requirement that certain income earned by controlled foreign corporations (CFCs) must be included currently in the gross income of the CFCs’ U.S. shareholder. GILTI is the excess of the shareholder’s “net CFC tested income” over the net deemed tangible income return, which is currently defined as the excess of (1) 10 percent of the aggregate of the U.S. shareholder’s pro rata share of the qualified business asset investment of each CFC with respect to which it is a U.S. shareholder over (2) the amount of certain interest expense taken into account in the determination of net CFC-tested income. Sysco will not be subject to the GILTI provisions until fiscal 2019.

Because of the complexity of the new GILTI tax rules, the company is continuing to evaluate this provision of the Tax Act and the application of ASC 740. Under U.S. GAAP, the company is allowed to make an accounting policy choice of either (1) treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current-period expense when incurred (the “period cost method”) or (2) factoring such amounts into a company’s measurement of its deferred taxes (the “deferred method”). Sysco’s selection of an accounting policy with respect to the new GILTI tax rules will depend, in part, on analyzing our global income to determine whether the company expects to have future U.S. inclusions in taxable income related to GILTI and, if so, what the impact is expected to be. Because whether Sysco expects to have future U.S. inclusions in taxable income related to GILTI depends not only on our current structure and estimated future results of global operations but also the company’s intent and ability to modify its structure and/or its business, Sysco is not yet able to reasonably estimate the effect of this provision of the Tax Act. Therefore, the company has not made any adjustments related to potential GILTI tax in its financial statements and has not made a policy decision regarding whether to record deferred taxes on GILTI.

Executive Compensation Limitation: The Tax Act expands the definition under Section 162(m) of the Internal Revenue Code (“Section 162(m)”) of covered employee and provides that, for specified employees, status as a covered employee continues for all subsequent tax years, including years after the death of the individual, and, among other modifications, repeals the exception for performance-based compensation and commissions from the $1 million deduction limitation. In addition, the Tax Act provides for transitional guidance that will allow certain payments made under written and binding agreements entered into prior to November 2, 2017 to be treated as if they were made under the provisions of Section 162(m) that were in effect prior to enactment of the Tax Act. The company is in the process of gathering information on existing compensation arrangements for covered employees as well as assessing the impact of transitional guidance on the realizability of existing deferred tax assets related to compensation arrangements of its covered employees. As a result, the company has not made any adjustments related to impacts of the new executive compensation limitations in its financial statements.

Indefinite Reinvestment Assertion: The company is in the process of assessing the impact of the Tax Act on its indefinite reinvestment assertion and the company’s plans to determine any associated impact on the financial statements. Therefore, no adjustments have been made in its financial statements with respect to its indefinite reinvestment assertion.

Effective Tax Rate

Sysco’s effective tax rate is reflective of the jurisdictions where the company has operations. The effective tax rates for the second quarter and first 26 weeks of fiscal 2018 were 37.11% and 34.71%, respectively. The effective tax rates for the second quarter and first 26 weeks of fiscal 2018 were negatively impacted by the transition tax described above resulting from the Tax Act. These effective tax rates were impacted favorably by a net tax benefit of $79.2 million attributable to the change in the federal statutory tax rate described above, along with the impact of tax law changes in certain foreign jurisdictions and excess tax benefits of equity-based compensation that totaled $8.1 million and $14.8 million, respectively. Sysco began recognizing these excess tax benefits within income tax expense in the first quarter of fiscal 2018 due to the adoption of ASU 2016-09. The effective tax rate for the second quarter of fiscal 2017 of 34.87% and the first 26 weeks of fiscal 2017 of 35.09% was favorably impacted by an increase in earnings in foreign jurisdictions due to the acquisition of the Brakes Group.

Uncertain Tax Positions

As of December 30, 2017, the gross amount of unrecognized tax benefit and related accrued interest was $16.2 million and $11.5 million, respectively. It is reasonably possible that the amount of the unrecognized tax benefit with respect to certain of the company’s unrecognized tax positions will increase or decrease in the next twelve months, either because Sysco prevails on positions challenged upon audit or because the company agrees to the disallowance. Items that may cause changes to unrecognized tax benefits primarily include the consideration of various filing requirements in numerous states and the allocation of income and expense between tax jurisdictions. At this time, an estimate of the range of the reasonably possible change cannot be made.

Other

The determination of the company’s provision for income taxes requires judgment, the use of estimates and the interpretation and application of complex tax laws. The company’s provision for income taxes reflects a combination of income earned and taxed in the various U.S. federal and state, as well as foreign, jurisdictions. Jurisdictional tax law changes, increases or decreases in permanent differences between book and tax items, accruals or adjustments of accruals for unrecognized tax benefits or valuation allowances, and the company’s change in the mix of earnings from these taxing jurisdictions all affect the overall effective tax rate.
