Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	Summary of Significant Accounting Policies Financial Statement Preparation The unaudited condensed consolidated financial statements as of April 1, 2018, and for the quarter and two quarters ended April 1, 2018 and April 2, 2017, have been prepared by Starbucks Corporation under the rules and regulations of the Securities and Exchange Commission (“SEC”). In the opinion of management, the financial information for the quarter and two quarters ended April 1, 2018 and April 2, 2017 reflects all adjustments and accruals, which are of a normal recurring nature, necessary for a fair presentation of the financial position, results of operations and cash flows for the interim periods. In this Quarterly Report on Form 10-Q (“10-Q”), Starbucks Corporation is referred to as “Starbucks,” the “Company,” “we,” “us” or “our.” The financial information as of October 1, 2017 is derived from our audited consolidated financial statements and notes for the fiscal year ended October 1, 2017 (“fiscal 2017”) included in Item 8 in the Fiscal 2017 Annual Report on Form 10-K (the “10-K”). The information included in this 10-Q should be read in conjunction with the footnotes and management’s discussion and analysis of the consolidated financial statements in the 10-K. The results of operations for the quarter and two quarters ended April 1, 2018 are not necessarily indicative of the results of operations that may be achieved for the entire fiscal year ending September 30, 2018 (“fiscal 2018”). Recent Accounting Pronouncements In February 2018, the Financial Accounting Standards Board (“FASB”) issued guidance on the reclassification of certain tax effects from accumulated other comprehensive income (“AOCI”). The guidance permits entities to reclassify the stranded tax effects resulting from the Tax Cuts and Jobs Act (the “Tax Act”) from AOCI to retained earnings. The guidance will be effective at the beginning of our first quarter of fiscal year 2020 but permits adoption in an earlier period. The guidance may be applied in the period of adoption or retrospectively to each period in which the effect of the change related to the Tax Act was recognized. We are currently evaluating the impact this guidance will have on our consolidated financial statements and the timing of adoption. In August 2017, the FASB amended its guidance on the financial reporting of hedging relationships. The new guidance eliminates the requirement to separately measure and report hedge ineffectiveness, expands permissible cash flow hedges on contractually specified components, and simplifies hedge documentation and effectiveness assessment. The guidance will be effective at the beginning of our first quarter of fiscal year 2020 and will require a modified retrospective approach on existing cash flow and net investment hedges. The presentation and disclosure requirements will be applied prospectively. We are currently evaluating the impact this guidance will have on our consolidated financial statements and the timing of adoption. In October 2016, the FASB issued guidance on the accounting for income tax effects of intercompany sales or transfers of assets other than inventory. The guidance requires entities to recognize the income tax impact of an intra-entity sale or transfer of an asset other than inventory when the sale or transfer occurs, rather than when the asset has been sold to an outside party. The guidance will require a modified retrospective application with a cumulative catch-up adjustment to opening retained earnings at the beginning of our first quarter of fiscal 2019 but permits adoption in an earlier period. We are currently evaluating the impact this guidance will have on our consolidated financial statements and the timing of adoption. In March 2016, the FASB issued guidance related to stock-based compensation, which changes the accounting and classification of excess tax benefits and minimum tax withholdings on share-based awards. This guidance requires that excess tax benefits and tax deficiencies related to stock-based compensation be prospectively reflected as income tax expense in our consolidated statement of earnings instead of additional paid-in capital on our consolidated balance sheet. Additionally, within our consolidated statement of cash flows, this guidance requires excess tax benefits to be presented as an operating activity, rather than a financing activity, in the same manner as other cash flows related to income taxes. We adopted this guidance in the first quarter of fiscal 2018. The primary impact of the adoption was the recognition of excess tax benefits that reduced income tax expenses by $16.2 million and $44.4 million for the quarter and two quarters ended April 1, 2018, respectively, instead of additional paid-in capital. As a result, net income increased $16.2 million and $44.4 million for the quarter and two quarters ended April 1, 2018, respectively and basic and diluted earnings per share increased $0.01 and $0.03 for the quarter and two quarters ended April 1, 2018, respectively. Excess tax benefits of $52.7 million, for the two quarters ended April 2, 2017, previously reported in financing activities have been reclassified to operating activities in the consolidated statements of cash flows. In March 2016, the FASB issued guidance for financial liabilities resulting from selling prepaid stored value products that are redeemable at third-party merchants. Under the new guidance, expected breakage amounts associated with these products must be recognized proportionately in earnings as redemption occurs. Our current accounting policy of applying the remote method to all of our stored value cards, including cards redeemable at the third-party licensed locations, will no longer be allowed. We will adopt and implement the provisions of this guidance and the new revenue recognition standard issued by the FASB, as discussed below, in the first quarter of fiscal 2019. In February 2016, the FASB issued guidance on the recognition and measurement of leases. Under the new guidance, lessees are required to recognize a lease liability, which represents the discounted obligation to make future minimum lease payments, and a corresponding right-of-use asset on the balance sheet for most leases. The guidance retains the current accounting for lessors and does not make significant changes to the recognition, measurement, and presentation of expenses and cash flows by a lessee. Enhanced disclosures will also be required to give financial statement users the ability to assess the amount, timing and uncertainty of cash flows arising from leases. The guidance will require modified retrospective application at the beginning of our first quarter of fiscal 2020, with optional practical expedients, but permits adoption in an earlier period. We are currently evaluating the impact this guidance will have on our consolidated financial statements. We expect this adoption will result in a material increase in the assets and liabilities on our consolidated balance sheets but will likely have an insignificant impact on our consolidated statements of earnings. In preparation for the adoption of the guidance, we are in the process of implementing controls and key system changes to enable the preparation of financial information. In May 2014, the FASB issued guidance outlining a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers that supersedes most current revenue recognition guidance. This guidance requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The new guidance may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of adoption. We are currently evaluating the overall impact this guidance will have on our consolidated financial statements, as well as the expected method of adoption. Based on our continued assessment, which may identify other accounting impacts, we have determined the adoption will change the timing of recognition and classification of our stored value card breakage income, which is currently recognized using the remote method and recorded in interest income and other, net. The new guidance will require application of the proportional method and classification within total net revenues on our consolidated statements of earnings. Additionally, the new guidance requires enhanced disclosures, including revenue recognition policies to identify performance obligations to customers and significant judgments in measurement and recognition. We will adopt this guidance in the first quarter of fiscal 2019.

Acquisitions and Divestitures


Note 2:	Acquisitions and Divestitures

Fiscal 2018

On March 23, 2018, we sold our company-operated retail store assets and operations in Brazil to SouthRock converting these operations to a fully licensed market, for a total of $48.2 million. This transaction resulted in a pre-tax loss of $8.5 million, which was included in loss from divestiture of certain operations on our consolidated statements of earnings.

On December 31, 2017, we acquired the remaining 50% interest of our East China joint venture (“East China”) from President Chain Store (Hong Kong) Holding Ltd. and Kai Yu (BVI) collectively, “Uni-President Group” or “UPG”, for approximately $1.4 billion. Approximately $86.3 million of pre-existing liabilities owed by East China to Starbucks were effectively settled upon the acquisition. Acquiring the remaining interest of East China, which operates over 1,400 stores in the Shanghai, Jiangsu and Zhejiang Provinces, builds on the Company's ongoing investment in China. The estimated fair values of the assets acquired and liabilities assumed are based on third party valuation and analysis performed by management. The valuation of certain assets and liabilities is preliminary and are subject to change as additional information becomes available.

Concurrently, with the purchase of our East China joint venture, we sold our 50% interest in President Starbucks Coffee Taiwan Limited, our joint venture operations in Taiwan, to UPG for approximately $181.2 million. The transaction resulted in a pre-tax gain of $156.6 million which was included in gains from divestiture of certain operations on our consolidated statements of earnings.

The following table summarizes the preliminary allocation of the total consideration to the fair values of the assets acquired and liabilities assumed as of December 31, 2017, which are reported within our China/Asia Pacific segment (in millions):



Consideration:
Cash paid for UPG 50% equity interest	$	1,440.8
Fair value of our pre-existing 50% equity interest	1,440.8
Settlement of pre-existing liabilities	86.3
Total consideration	$	2,967.9

Fair value of assets acquired and liabilities assumed:
Cash and cash equivalents	$	129.5
Accounts receivable	14.3
Inventories	15.9
Prepaid expenses and other current assets	20.6
Property, plant and equipment	253.9
Other long-term assets	44.6
Other intangible assets	818.0
Goodwill	2,158.1
Total assets acquired	3,454.9
Accounts payable	43.1
Accrued liabilities	177.3
Stored value card liability	21.7
Other long-term liabilities	244.9
Total liabilities assumed	487.0
Total consideration	$	2,967.9

As a result of this acquisition, we remeasured the carrying value of our preexisting 50% equity method investment to fair value, which resulted in a total gain of $1.4 billion that is not subject to income tax, and was presented as gain resulting from acquisition of joint venture on our consolidated statements of earnings. The fair value of $1.4 billion was calculated using an income approach, which was based on significant inputs that are not observable in the market and thus represents a fair value measurement categorized within Level 3 of the fair value hierarchy. Key assumptions used in estimating future cash flows included projected revenue growth and operating expenses, as well as the selection of an appropriate discount rate. Estimates of revenue growth and operating expenses were based on internal projections and considered the historical performance of stores, local market economics and the business environments impacting store performance. The discount rate applied was based on East China's weighted-average cost of capital and included company-specific and size risk premiums.

In the second quarter of fiscal 2018, we finalized our purchase price based on East China's calendar year 2017 results which resulted in an acquisition gain adjustment of $47.6 million. The acquisition date fair value of goodwill was increased by $21 million, due to the purchase price update and various immaterial revisions to assets acquired and liabilities assumed.

The assets acquired and liabilities assumed are reported within our China/Asia Pacific segment. Other current and long-term assets acquired primarily include lease deposits and prepaid rent. Accrued liabilities and other long-term liabilities assumed primarily include deferred income tax, dividend payable, accrued payroll, income tax payable and accrued occupancy costs.

The definite-lived intangibles primarily relate to reacquired rights to operate stores exclusively in East China. The reacquired rights of $798.0 million represent the fair value calculated over the remaining original contractual period and will be amortized on a straight-line basis through September 2022. Amortization expense for these definite-lived intangible assets for the quarter ended April 1, 2018 was $44.4 million and the estimated future amortization expense is approximately $90.0 million in fiscal 2018, $180.1 million each year for the next three years and approximately $172.9 million in the final year of fiscal 2022.

Goodwill represents the intangible assets that do not qualify for separate recognition and primarily includes the acquired customer base, the acquired workforce including store partners in the region that have strong relationships with these customers, and the existing geographic retail and online presence. The entire balance was allocated to the China/Asia Pacific segment and is not deductible for income tax purposes. Due to foreign currency translation, the balance of goodwill related to the acquisition increased $78.8 million to $2.2 billion as of April 1, 2018.

The table below summarizes our estimated minimum future rental payments under the acquired non-cancelable operating leases as of April 1, 2018 (in millions):



	Operating Leases
Year 1	$	72.2
Year 2	62.6
Year 3	53.7
Year 4	46.6
Year 5	37.0
Thereafter	80.5
Total minimum lease payments	$	352.6

We began consolidating East China's results of operations and cash flows into our consolidated financial statements after December 31, 2017. For the quarter ended April 1, 2018, East China's revenue included in our consolidated statements of earnings was $301.6 million. For the quarter ended April 1, 2018, East China's net earnings included in our consolidated statements of earnings was $26.2 million.

The following table provides the supplemental pro forma revenue and net earnings of the combined entity had the acquisition date of East China been October 3, 2016, the first day of our first quarter of fiscal 2017, rather than the end of our first quarter of fiscal 2018 (in millions):



	Pro Forma (unaudited)
	Quarter Ended				Two Quarters Ended
	Apr 1, 2018		Apr 2, 2017⁽¹⁾		Apr 1, 2018		Apr 2, 2017 ⁽¹⁾
Revenue	$	6,031.8	$	5,516.1	$	12,376.5	$	11,464.1
Net earnings attributable to Starbucks	568.8		759.3		1,691.6		2,558.5


⁽¹⁾	The pro forma net earnings attributable to Starbucks for fiscal 2017 includes the acquisition-related gain of $47.6 million and $1,373.9 million and transaction and integration costs of $8.7 million and $12.4 million for the quarter and two quarters ended April 2, 2017, respectively.

The amounts in the supplemental pro forma earnings for the periods presented above fully eliminate intercompany transactions, apply our accounting policies and reflect adjustments for additional occupancy costs as well as depreciation and amortization that would have been charged assuming the same fair value adjustments to leases, property, plant and equipment and acquired intangibles had been applied on October 3, 2016. These pro forma results are unaudited and are not necessarily indicative of results of operations that would have occurred had the acquisition actually closed in the prior year period or indicative of the results of operations for any future period.

During the quarter and two quarters ended April 1, 2018, we incurred approximately $0.4 million and $2.9 million, respectively, of acquisition-related costs, such as regulatory, legal, and advisory fees, which we have recorded in general and administrative expenses.

On December 11, 2017, we sold the assets associated with our Tazo brand including Tazo^® signature recipes, intellectual property and inventory to Unilever for a total of $383.8 million. The transaction resulted in a pre-tax gain of $347.9 million, which was included in gains from divestiture of certain operations on our consolidated statements of earnings. Results from Tazo operations prior to the sale are reported primarily in Channel Development.

Fiscal 2017

In the fourth quarter of fiscal 2017, we sold our company-operated retail store assets and operations in Singapore to Maxim's Caterers Limited, converting these operations to a fully licensed market, for a total of $119.9 million. This transaction resulted in a pre-tax gain of $83.9 million, which was included in interest income and other, net on our consolidated statements of earnings. An insignificant settlement related to the divestiture was received in the first quarter of 2018 and included in gains from divestiture of certain operations on our consolidated statements of earnings.

Fiscal 2018

On March 23, 2018, we sold our company-operated retail store assets and operations in Brazil to SouthRock converting these operations to a fully licensed market, for a total of $48.2 million. This transaction resulted in a pre-tax loss of $8.5 million, which was included in loss from divestiture of certain operations on our consolidated statements of earnings.

On December 31, 2017, we acquired the remaining 50% interest of our East China joint venture (“East China”) from President Chain Store (Hong Kong) Holding Ltd. and Kai Yu (BVI) collectively, “Uni-President Group” or “UPG”, for approximately $1.4 billion. Approximately $86.3 million of pre-existing liabilities owed by East China to Starbucks were effectively settled upon the acquisition. Acquiring the remaining interest of East China, which operates over 1,400 stores in the Shanghai, Jiangsu and Zhejiang Provinces, builds on the Company's ongoing investment in China. The estimated fair values of the assets acquired and liabilities assumed are based on third party valuation and analysis performed by management. The valuation of certain assets and liabilities is preliminary and are subject to change as additional information becomes available.

Concurrently, with the purchase of our East China joint venture, we sold our 50% interest in President Starbucks Coffee Taiwan Limited, our joint venture operations in Taiwan, to UPG for approximately $181.2 million. The transaction resulted in a pre-tax gain of $156.6 million which was included in gains from divestiture of certain operations on our consolidated statements of earnings.

The following table summarizes the preliminary allocation of the total consideration to the fair values of the assets acquired and liabilities assumed as of December 31, 2017, which are reported within our China/Asia Pacific segment (in millions):



Consideration:
Cash paid for UPG 50% equity interest	$	1,440.8
Fair value of our pre-existing 50% equity interest	1,440.8
Settlement of pre-existing liabilities	86.3
Total consideration	$	2,967.9

Fair value of assets acquired and liabilities assumed:
Cash and cash equivalents	$	129.5
Accounts receivable	14.3
Inventories	15.9
Prepaid expenses and other current assets	20.6
Property, plant and equipment	253.9
Other long-term assets	44.6
Other intangible assets	818.0
Goodwill	2,158.1
Total assets acquired	3,454.9
Accounts payable	43.1
Accrued liabilities	177.3
Stored value card liability	21.7
Other long-term liabilities	244.9
Total liabilities assumed	487.0
Total consideration	$	2,967.9

As a result of this acquisition, we remeasured the carrying value of our preexisting 50% equity method investment to fair value, which resulted in a total gain of $1.4 billion that is not subject to income tax, and was presented as gain resulting from acquisition of joint venture on our consolidated statements of earnings. The fair value of $1.4 billion was calculated using an income approach, which was based on significant inputs that are not observable in the market and thus represents a fair value measurement categorized within Level 3 of the fair value hierarchy. Key assumptions used in estimating future cash flows included projected revenue growth and operating expenses, as well as the selection of an appropriate discount rate. Estimates of revenue growth and operating expenses were based on internal projections and considered the historical performance of stores, local market economics and the business environments impacting store performance. The discount rate applied was based on East China's weighted-average cost of capital and included company-specific and size risk premiums.

In the second quarter of fiscal 2018, we finalized our purchase price based on East China's calendar year 2017 results which resulted in an acquisition gain adjustment of $47.6 million. The acquisition date fair value of goodwill was increased by $21 million, due to the purchase price update and various immaterial revisions to assets acquired and liabilities assumed.

The assets acquired and liabilities assumed are reported within our China/Asia Pacific segment. Other current and long-term assets acquired primarily include lease deposits and prepaid rent. Accrued liabilities and other long-term liabilities assumed primarily include deferred income tax, dividend payable, accrued payroll, income tax payable and accrued occupancy costs.

The definite-lived intangibles primarily relate to reacquired rights to operate stores exclusively in East China. The reacquired rights of $798.0 million represent the fair value calculated over the remaining original contractual period and will be amortized on a straight-line basis through September 2022. Amortization expense for these definite-lived intangible assets for the quarter ended April 1, 2018 was $44.4 million and the estimated future amortization expense is approximately $90.0 million in fiscal 2018, $180.1 million each year for the next three years and approximately $172.9 million in the final year of fiscal 2022.

Goodwill represents the intangible assets that do not qualify for separate recognition and primarily includes the acquired customer base, the acquired workforce including store partners in the region that have strong relationships with these customers, and the existing geographic retail and online presence. The entire balance was allocated to the China/Asia Pacific segment and is not deductible for income tax purposes. Due to foreign currency translation, the balance of goodwill related to the acquisition increased $78.8 million to $2.2 billion as of April 1, 2018.

The table below summarizes our estimated minimum future rental payments under the acquired non-cancelable operating leases as of April 1, 2018 (in millions):



	Operating Leases
Year 1	$	72.2
Year 2	62.6
Year 3	53.7
Year 4	46.6
Year 5	37.0
Thereafter	80.5
Total minimum lease payments	$	352.6

We began consolidating East China's results of operations and cash flows into our consolidated financial statements after December 31, 2017. For the quarter ended April 1, 2018, East China's revenue included in our consolidated statements of earnings was $301.6 million. For the quarter ended April 1, 2018, East China's net earnings included in our consolidated statements of earnings was $26.2 million.

The following table provides the supplemental pro forma revenue and net earnings of the combined entity had the acquisition date of East China been October 3, 2016, the first day of our first quarter of fiscal 2017, rather than the end of our first quarter of fiscal 2018 (in millions):



	Pro Forma (unaudited)
	Quarter Ended				Two Quarters Ended
	Apr 1, 2018		Apr 2, 2017⁽¹⁾		Apr 1, 2018		Apr 2, 2017 ⁽¹⁾
Revenue	$	6,031.8	$	5,516.1	$	12,376.5	$	11,464.1
Net earnings attributable to Starbucks	568.8		759.3		1,691.6		2,558.5


⁽¹⁾	The pro forma net earnings attributable to Starbucks for fiscal 2017 includes the acquisition-related gain of $47.6 million and $1,373.9 million and transaction and integration costs of $8.7 million and $12.4 million for the quarter and two quarters ended April 2, 2017, respectively.

The amounts in the supplemental pro forma earnings for the periods presented above fully eliminate intercompany transactions, apply our accounting policies and reflect adjustments for additional occupancy costs as well as depreciation and amortization that would have been charged assuming the same fair value adjustments to leases, property, plant and equipment and acquired intangibles had been applied on October 3, 2016. These pro forma results are unaudited and are not necessarily indicative of results of operations that would have occurred had the acquisition actually closed in the prior year period or indicative of the results of operations for any future period.

During the quarter and two quarters ended April 1, 2018, we incurred approximately $0.4 million and $2.9 million, respectively, of acquisition-related costs, such as regulatory, legal, and advisory fees, which we have recorded in general and administrative expenses.

On December 11, 2017, we sold the assets associated with our Tazo brand including Tazo^® signature recipes, intellectual property and inventory to Unilever for a total of $383.8 million. The transaction resulted in a pre-tax gain of $347.9 million, which was included in gains from divestiture of certain operations on our consolidated statements of earnings. Results from Tazo operations prior to the sale are reported primarily in Channel Development.

Fiscal 2017

In the fourth quarter of fiscal 2017, we sold our company-operated retail store assets and operations in Singapore to Maxim's Caterers Limited, converting these operations to a fully licensed market, for a total of $119.9 million. This transaction resulted in a pre-tax gain of $83.9 million, which was included in interest income and other, net on our consolidated statements of earnings. An insignificant settlement related to the divestiture was received in the first quarter of 2018 and included in gains from divestiture of certain operations on our consolidated statements of earnings.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

Interest Rates

We are subject to interest rate volatility with regard to existing and future issuances of debt. From time to time, we enter into swap agreements to manage our exposure to interest rate fluctuations.

To hedge the variability in cash flows due to changes in benchmark interest rates, we enter into interest rate swap agreements related to anticipated debt issuances. These agreements are cash settled at the time of the pricing of the related debt. The effective portion of the derivative's gain or loss is recorded in accumulated other comprehensive income (“AOCI”) and is subsequently reclassified to interest expense over the life of the related debt.

To hedge the exposure to changes in the fair value of our fixed-rate debt, we enter into interest rate swap agreements, which are designated as fair value hedges. The changes in fair values of these derivative instruments and the offsetting changes in fair values of the underlying hedged debt are recorded in interest expense and have an insignificant impact on our condensed consolidated statement of earnings. Refer to Note 8, Debt, for additional information on our long-term debt.

Foreign Currency

To reduce cash flow volatility from foreign currency fluctuations, we enter into forward and swap contracts to hedge portions of cash flows of anticipated intercompany royalty payments, inventory purchases, and intercompany borrowing and lending activities. The effective portion of the derivative's gain or loss is recorded in AOCI and is subsequently reclassified to revenue, cost of sales including occupancy costs, or interest income and other, net, respectively, when the hedged exposure affects net earnings.

From time to time, we enter into forward contracts or use foreign currency-denominated debt to hedge the currency exposure of our net investment in certain international operations. The effective portion of these instruments' gain or loss is recorded in AOCI and is subsequently reclassified to net earnings when the hedged net investment is either sold or substantially liquidated.

Foreign currency forward and swap contracts not designated as hedging instruments are used to mitigate the foreign exchange risk of certain other balance sheet items. Gains and losses from these derivatives are largely offset by the financial impact of translating foreign currency denominated payables and receivables; these gains and losses are recorded in interest income and other, net.

Commodities

Depending on market conditions, we may enter into coffee futures contracts and collars (the combination of a purchased call option and a sold put option) to hedge a portion of anticipated cash flows under our price-to-be-fixed green coffee contracts, which are described further in Note 5, Inventories. The effective portion of each derivative's gain or loss is recorded in AOCI and is subsequently reclassified to cost of sales including occupancy costs when the hedged exposure affects net earnings.

To mitigate the price uncertainty of a portion of our future purchases, primarily of dairy products, diesel fuel and other commodities, we enter into swap contracts, futures and collars that are not designated as hedging instruments. Gains and losses from these derivatives are recorded in interest income and other, net to help offset price fluctuations on our beverage, food, packaging and transportation costs, which are included in cost of sales including occupancy costs on our consolidated statements of earnings.

There were no material transfers between levels, and there was no significant activity within Level 3 instruments during the periods presented. The fair values of any financial instruments presented above exclude the impact of netting assets and liabilities when a legally enforceable master netting agreement exists.

Gross unrealized holding gains and losses on investments were not material as of April 1, 2018 and October 1, 2017.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

Assets and liabilities recognized or disclosed at fair value on the condensed consolidated financial statements on a nonrecurring basis include items such as property, plant and equipment, goodwill and other intangible assets, equity and cost method investments and other assets. These assets are measured at fair value if determined to be impaired.

The strength of the Swiss franc, continued shift of consumer behaviors to neighboring countries and the relocations of certain businesses in recent years have sustained beyond our prior projections. Moreover, the investments and improvements we have made have not sufficiently slowed the performance decline as quickly as we anticipated. Therefore, we do not expect to fully recover the Switzerland retail reporting unit's carrying value and recorded a goodwill impairment charge of $28.5 million during the second quarter of fiscal 2018.

Other than the aforementioned fair value adjustment, there were no other material fair value adjustments during the quarter and two quarters ended April 1, 2018 and April 2, 2017. The estimated fair value of our long-term debt based on the quoted market price (Level 2) is included at Note 8, Debt.

Other merchandise held for sale includes, among other items, serveware and tea. Inventory levels vary due to seasonality, commodity market supply and price fluctuations.

As of April 1, 2018, we had committed to purchasing green coffee totaling $631 million under fixed-price contracts and an estimated $547 million under price-to-be-fixed contracts. As of April 1, 2018, none of our price-to-be fixed contracts were effectively fixed through the use of futures contracts. Price-to-be-fixed contracts are purchase commitments whereby the quality, quantity, delivery period, and other negotiated terms are agreed upon, but the date, and therefore the price, at which the base “C” coffee commodity price component will be fixed has not yet been established. For most contracts, either Starbucks or the seller has the option to “fix” the base “C” coffee commodity price prior to the delivery date. For other contracts, Starbucks and the seller may agree upon pricing parameters determined by the base “C” coffee commodity price. Until prices are fixed, we estimate the total cost of these purchase commitments. We believe, based on relationships established with our suppliers in the past, the risk of non-delivery on these purchase commitments is remote.

Income Taxes	Apr. 01, 2018
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our interim tax provision is determined using an estimated annual effective tax rate and adjusted for discrete taxable events that may occur during the quarter. We recognize the effects of tax legislation in the period in which the law is enacted. Our deferred tax assets and liabilities are remeasured using enacted tax rates expected to apply to taxable income in the years we estimate the related temporary differences to reverse. On December 22, 2017, the President of the United States signed and enacted comprehensive tax legislation into law H.R. 1, commonly referred to as the Tax Act. Except for certain provisions, the Tax Act is effective for tax years beginning on or after January 1, 2018. As a fiscal year U.S. taxpayer, the majority of the provisions will apply to our fiscal 2019, such as eliminating the domestic manufacturing deduction, creating new taxes on certain foreign sourced income and introducing new limitations on certain business deductions. For fiscal 2018 and effective in the first fiscal quarter, the most significant impacts include: lowering of the U.S. federal corporate income tax rate; remeasuring certain net deferred tax liabilities; and requiring the transition tax on the deemed repatriation of certain foreign earnings. The phase in of the lower corporate income tax rate resulted in a blended rate of 24.5% for fiscal 2018, as compared to the previous 35%. The tax rate will be reduced to 21% in subsequent fiscal years. We recorded net income tax benefit for the provisional remeasurement of certain deferred taxes and related amounts of $76 million for the two quarters ended April 1, 2018. Additionally, we recorded a provisional $26 million and $238 million of income tax expense for the estimated effects of the transition tax, net of adjustments related to uncertain tax positions for the quarter and two quarters ended April 1, 2018, respectively. Of the total provisional transition tax obligation recorded to date, $246 million of income taxes payable was included in other long-term liabilities on the condensed consolidated balance sheet as of April 1, 2018. Based on our current interpretation of the Tax Act, we made reasonable estimates to record provisional adjustments during the first quarter of fiscal 2018, as described above. Collectively, these items did not have a material impact to our condensed consolidated financial statements. Since we are still accumulating and processing data to finalize the underlying calculations and expect regulators to issue further guidance, among other things, we believe our estimates may change during fiscal 2018. We continue to refine such amounts within the measurement period allowed, which will be completed no later than the first quarter of fiscal 2019.

Potential dilutive shares consist of the incremental common shares issuable upon the exercise of outstanding stock options (both vested and nonvested) and unvested RSUs, calculated using the treasury stock method. The calculation of dilutive shares outstanding excludes out-of-the-money stock options (i.e., such options’ exercise prices were greater than the average market price of our common shares for the period) because their inclusion would have been antidilutive. Out-of-the-money stock options totaled approximately 4.8 million and 5.2 million as of April 1, 2018 and April 2, 2017, respectively.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure [Text Block]	Commitments and Contingencies Legal Proceedings On April 13, 2010, an organization named Council for Education and Research on Toxics (“Plaintiff”) filed a lawsuit in the Superior Court of the State of California, County of Los Angeles, against the Company and certain other defendants who manufacture, package, distribute or sell coffee. The lawsuit is Council for Education and Research on Toxics v. Starbucks Corporation, et al.. On May 9, 2011, the Plaintiffs filed an additional lawsuit in the Superior Court of the State of California, County of Los Angeles, against the Company and additional defendants who manufacture, package, distribute or sell coffee. The lawsuit is Council for Education and Research on Toxics v. Brad Barry LLC, et al.. Both cases have since been consolidated for all purposes as __________________and now include nearly one hundred defendants. Plaintiff alleges that the Company and the other defendants failed to provide warnings of the chemical acrylamide under section 25249.5 of the California Safe Drinking Water and Toxic Enforcement Act of 1986, better known as Proposition 65. Plaintiff seeks equitable relief, including providing warnings to consumers, as well as civil penalties in the amount of the statutory maximum of two thousand five hundred dollars per day per violation of Proposition 65. The Plaintiff asserts that every consumed cup of coffee, absent a compliant warning, is equivalent to a violation under Proposition 65. The Company, as part of a joint defense group organized to defend against the lawsuit, disputes the claims of the Plaintiff. Acrylamide is not added to coffee, but is present in all coffee in small amounts (parts per billion) as a byproduct of the coffee bean roasting process. The Company has asserted multiple affirmative defenses. Trial of the first phase of the case commenced on September 8, 2014 and was limited to three affirmative defenses shared by all defendants. On September 1, 2015, the trial court issued a final ruling adverse to defendants on all Phase 1 defenses. Trial of the second phase of the case commenced in the fall of 2017. On March 28, 2018, the trial court issued a proposed ruling adverse to defendants on the Phase 2 defense, the Company’s last remaining defense to liability. The March 28^thruling is not final. Should the trial court finalize and affirm its proposed ruling in Phase 2, trial would proceed to a third phase regarding remedies issues. At this stage of the proceedings, prior to a trial on remedies issues, Starbucks is unable to predict the potential loss or effect on the Company or its operations. The trial court has discretion to impose zero penalties against the Company or to impose significant statutory penalties. Significant labeling or warning requirements that could potentially be imposed by the trial court may increase our costs and adversely affect sales of our coffee products, as well as, involve substantial expense and operational disruption, which could have a material adverse impact on our financial position and our results of operations. Furthermore, a future appellate court decision could reverse the trial court rulings. The outcome and the financial impact of settlement or the trial or appellate court rulings of the case to the Company, if any, cannot be predicted. Starbucks is party to various other legal proceedings arising in the ordinary course of business, including certain employment litigation cases that have been certified as class or collective actions, but, except as noted above, is not currently a party to any legal proceeding that management believes could have a material adverse effect on our consolidated financial position, results of operations or cash flows.

The existing portfolio of Teavana stores are expected to be closed during fiscal 2018. Lease exit costs associated with our restructuring efforts will be recognized concurrently with either actual store closures or upon reaching a lease termination agreement with the landlord. Total lease exit costs are expected to be approximately $134.5 million of which $100.9 million and $117.5 million were recorded within restructuring expenses on the consolidated statement of earnings in the quarter and two quarters ended April 1, 2018, respectively. During the first two quarters of 2017, we did not record any restructuring expenses. Previously recorded lease exit costs recorded within restructuring expenses for fiscal year 2017 were $15.7 million.

Summary of Significant Accounting Policies Summary of Significant Policies (Policies)	6 Months Ended

Accounting Policies [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements In February 2018, the Financial Accounting Standards Board (“FASB”) issued guidance on the reclassification of certain tax effects from accumulated other comprehensive income (“AOCI”). The guidance permits entities to reclassify the stranded tax effects resulting from the Tax Cuts and Jobs Act (the “Tax Act”) from AOCI to retained earnings. The guidance will be effective at the beginning of our first quarter of fiscal year 2020 but permits adoption in an earlier period. The guidance may be applied in the period of adoption or retrospectively to each period in which the effect of the change related to the Tax Act was recognized. We are currently evaluating the impact this guidance will have on our consolidated financial statements and the timing of adoption. In August 2017, the FASB amended its guidance on the financial reporting of hedging relationships. The new guidance eliminates the requirement to separately measure and report hedge ineffectiveness, expands permissible cash flow hedges on contractually specified components, and simplifies hedge documentation and effectiveness assessment. The guidance will be effective at the beginning of our first quarter of fiscal year 2020 and will require a modified retrospective approach on existing cash flow and net investment hedges. The presentation and disclosure requirements will be applied prospectively. We are currently evaluating the impact this guidance will have on our consolidated financial statements and the timing of adoption. In October 2016, the FASB issued guidance on the accounting for income tax effects of intercompany sales or transfers of assets other than inventory. The guidance requires entities to recognize the income tax impact of an intra-entity sale or transfer of an asset other than inventory when the sale or transfer occurs, rather than when the asset has been sold to an outside party. The guidance will require a modified retrospective application with a cumulative catch-up adjustment to opening retained earnings at the beginning of our first quarter of fiscal 2019 but permits adoption in an earlier period. We are currently evaluating the impact this guidance will have on our consolidated financial statements and the timing of adoption. In March 2016, the FASB issued guidance related to stock-based compensation, which changes the accounting and classification of excess tax benefits and minimum tax withholdings on share-based awards. This guidance requires that excess tax benefits and tax deficiencies related to stock-based compensation be prospectively reflected as income tax expense in our consolidated statement of earnings instead of additional paid-in capital on our consolidated balance sheet. Additionally, within our consolidated statement of cash flows, this guidance requires excess tax benefits to be presented as an operating activity, rather than a financing activity, in the same manner as other cash flows related to income taxes. We adopted this guidance in the first quarter of fiscal 2018. The primary impact of the adoption was the recognition of excess tax benefits that reduced income tax expenses by $16.2 million and $44.4 million for the quarter and two quarters ended April 1, 2018, respectively, instead of additional paid-in capital. As a result, net income increased $16.2 million and $44.4 million for the quarter and two quarters ended April 1, 2018, respectively and basic and diluted earnings per share increased $0.01 and $0.03 for the quarter and two quarters ended April 1, 2018, respectively. Excess tax benefits of $52.7 million, for the two quarters ended April 2, 2017, previously reported in financing activities have been reclassified to operating activities in the consolidated statements of cash flows. In March 2016, the FASB issued guidance for financial liabilities resulting from selling prepaid stored value products that are redeemable at third-party merchants. Under the new guidance, expected breakage amounts associated with these products must be recognized proportionately in earnings as redemption occurs. Our current accounting policy of applying the remote method to all of our stored value cards, including cards redeemable at the third-party licensed locations, will no longer be allowed. We will adopt and implement the provisions of this guidance and the new revenue recognition standard issued by the FASB, as discussed below, in the first quarter of fiscal 2019. In February 2016, the FASB issued guidance on the recognition and measurement of leases. Under the new guidance, lessees are required to recognize a lease liability, which represents the discounted obligation to make future minimum lease payments, and a corresponding right-of-use asset on the balance sheet for most leases. The guidance retains the current accounting for lessors and does not make significant changes to the recognition, measurement, and presentation of expenses and cash flows by a lessee. Enhanced disclosures will also be required to give financial statement users the ability to assess the amount, timing and uncertainty of cash flows arising from leases. The guidance will require modified retrospective application at the beginning of our first quarter of fiscal 2020, with optional practical expedients, but permits adoption in an earlier period. We are currently evaluating the impact this guidance will have on our consolidated financial statements. We expect this adoption will result in a material increase in the assets and liabilities on our consolidated balance sheets but will likely have an insignificant impact on our consolidated statements of earnings. In preparation for the adoption of the guidance, we are in the process of implementing controls and key system changes to enable the preparation of financial information. In May 2014, the FASB issued guidance outlining a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers that supersedes most current revenue recognition guidance. This guidance requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The new guidance may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of adoption. We are currently evaluating the overall impact this guidance will have on our consolidated financial statements, as well as the expected method of adoption. Based on our continued assessment, which may identify other accounting impacts, we have determined the adoption will change the timing of recognition and classification of our stored value card breakage income, which is currently recognized using the remote method and recorded in interest income and other, net. The new guidance will require application of the proportional method and classification within total net revenues on our consolidated statements of earnings. Additionally, the new guidance requires enhanced disclosures, including revenue recognition policies to identify performance obligations to customers and significant judgments in measurement and recognition. We will adopt this guidance in the first quarter of fiscal 2019.
