| Summary Of Significant Accounting Policies | Summary of Significant Accounting Policies Financial Statement Preparation The unaudited condensed consolidated financial statements as of March 31, 2019, and for the quarter and two quarters ended March 31, 2019 and April 1, 2018, 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 March 31, 2019 and April 1, 2018 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.” Certain prior period information on the condensed consolidated statements of cash flows has been reclassified to conform to the current year presentation. The financial information as of September 30, 2018 is derived from our audited consolidated financial statements and notes for the fiscal year ended September 30, 2018 (“fiscal 2018”) included in Item 8 in the Fiscal 2018 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 March 31, 2019 are not necessarily indicative of the results of operations that may be achieved for the entire fiscal year ending September 29, 2019 (“fiscal 2019”). Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements In the first quarter of fiscal 2019, we adopted the Financial Accounting Standards Board (“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 primary impact of the adoption was an increase to deferred income taxes, net of $227.6 million and a corresponding cumulative adjustment to opening retained earnings at the beginning of fiscal 2019. In the first quarter of fiscal 2019, we adopted the new guidance on revenue recognition utilizing the modified retrospective method, which primarily changed the accounting method and classification of revenue recognition related to unredeemed stored value cards, referred to as stored value card breakage. Under this new guidance, expected breakage amounts must be recognized proportionately in earnings as redemptions occur. Previously, stored value card breakage was recorded to interest income and other, net utilizing the remote method. Starting in the first quarter of 2019, stored value card breakage was recorded in the revenue lines where stored value cards may be redeemed—primarily company-operated and licensed store revenues. The cumulative impact to retained earnings as of October 1, 2018 was $268.0 million. Impact of adoption on our consolidated balance sheet at September 30, 2018:
Due to the adoption, we began classifying stored value card liabilities as current and long-term deferred revenue. See Note 2, Revenue Recognition, for further discussion of classification of impacts of the adoption. Recent Accounting Pronouncements Not Yet Adopted In February 2018, the 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 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 do not expect a material impact upon adoption of this guidance. In August 2017, the FASB amended its guidance on the accounting for 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 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 do not expect this guidance to have a material impact to our consolidated financial statements and may elect to adopt during the second half 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 be effective at the beginning of our first quarter of fiscal 2020, with optional practical expedients. As permitted by the alternative method issued by the FASB, we will be applying the guidance at the beginning of the year of adoption. 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. Revision of Previously Issued Financial Statements We have revised our condensed consolidated statement of comprehensive income and the related footnotes for the quarter and two quarters ended April 1, 2018 to reflect the correction of an immaterial error primarily related to the reclassification of gains and losses resulting from cash flow hedges from accumulated other comprehensive income to net income. Total other comprehensive income was not changed.

| Revenue Recognition [Abstract] | |
| Revenue Recognition, Policy [Policy Text Block] | The following significant revenue recognition accounting policies from our most recent Annual Report on Form 10-K have been restated to reflect the adoption of the new guidance. Consolidated revenues are presented net of intercompany eliminations for wholly-owned subsidiaries and investees controlled by us and for product sales to and royalty and other fees from licensees accounted for under the equity method. Additionally, consolidated revenues are recognized net of any discounts, returns, allowances and sales incentives, including coupon redemptions and rebates. Company-operated Store Revenues Company-operated store revenues are recognized when payment is tendered at the point of sale as the performance obligation has been satisfied. Company-operated store revenues are reported excluding sales, use or other transaction taxes that are collected from customers and remitted to taxing authorities. Licensed Store Revenues Licensed store revenues consist of product and equipment sales, royalties and other fees paid by licensees to use the Starbucks brand and for services such as training and design. Sales of coffee, tea, food and related products are generally recognized upon shipment to licensees, depending on contract terms. Shipping charges billed to licensees are also recognized as revenue, and the related shipping costs are included in cost of sales including occupancy costs on our condensed consolidated statements of earnings. Initial nonrefundable pre-opening service fees, including site selection and evaluation, store development and design and operational training, are recognized upon completion of services. Royalty revenues are recognized based upon a percentage of reported sales, and other continuing fees, such as marketing and service fees, are recognized as the performance obligations are met. Stored Value Cards Stored value cards can be activated through various channels, including at our company-operated and most licensed store locations, online at Starbucks.com or via mobile devices held by our customers, and at certain other third-party websites and locations, such as grocery stores, although they cannot be reloaded at these third-party websites or locations. Amounts loaded onto stored value cards are initially recorded as deferred revenue and recognized as revenue upon redemption. Historically, the majority of stored value cards are redeemed within one year. In many of our company-owned markets, including the U.S., our stored value cards do not have an expiration date nor do we charge service fees that cause a decrement to customer balances. Based on historical redemption rates, a portion of stored value cards is not expected to be redeemed and will be recognized as breakage over time in proportion to stored value card redemptions. The redemption rates are based on historical redemption patterns for each market, including the timing and business channel in which the card was activated, and unclaimed property laws, if applicable. Breakage is recognized as company-operated stores and licensed stores revenue within the condensed consolidated statement of earnings. For the quarter and two quarters ended March 31, 2019, we recognized breakage revenue of $37.5 million and $72.3 million in company-operated store revenues and $4.7 million and $9.3 million in licensed store revenues, respectively. Prior to fiscal 2019, breakage was recorded using the remote method and recorded in interest income and other, net. There were no material impacts to the financial results for the quarter and two quarters ended March 31, 2019, respectively, including the change in income statement presentation. Loyalty Program Customers in the U.S., Canada, and certain other countries who register their Starbucks Card are automatically enrolled in the Starbucks® Rewards program, which is primarily a spend-based loyalty program. They earn loyalty points (“Stars”) with each purchase at participating Starbucks® stores and when making purchases with the Starbucks-branded credit and debit cards. After accumulating a certain number of Stars, the customer earns a reward that can be redeemed for free product that, regardless of where the related Stars were earned within that country, will be honored at company-operated stores and certain participating licensed store locations in that same country. We defer revenue associated with the estimated selling price of Stars earned by Starbucks® Rewards members towards free product as each Star is earned and a corresponding liability is established in deferred revenue. This deferral is based on the estimated value of the product for which the reward is expected to be redeemed, net of estimated unredeemed Stars. Stars generally expire after six months. When a customer redeems an earned reward, we recognize revenue for the redeemed product and reduce the related deferred revenue. The new guidance does not impact the timing or total revenue recognized related to the loyalty program. Other Revenues Other revenues primarily include royalty revenues, sales of packaged coffee, tea and a variety of ready-to-drink beverages and single-serve coffee and tea products to customers outside of our company-operated and licensed stores. Sales of these products are generally recognized upon shipment to customers, depending on contract terms. Beginning in late fiscal 2018, other revenues also include product sales to and licensing revenue from Nestlé related to our Global Coffee Alliance. Product sales to Nestlé are generally recognized when the product is shipped whereas royalty revenues are recognized based on a percentage of reported sales. The timing and amount of revenue recognized related to other revenues were not impacted by the adoption of new guidance. Deferred Revenues In the fourth quarter of fiscal 2018, we licensed the rights to sell and market our products in authorized channels to Nestlé, or the “Global Coffee Alliance,” and also received an upfront prepaid royalty. The upfront payment of approximately $7 billion was recorded as deferred revenue as we have continuing performance obligations to support the Global Coffee Alliance, including providing Nestlé access to certain intellectual properties and products for future resale. The upfront payment will be recognized as other revenue on a straight-line basis over the estimated economic life of the arrangement of 40 years. At March 31, 2019, the current and long-term deferred revenue related to the Nestlé upfront payment was $174.0 million and $6.7 billion, respectively. Additionally, deferred revenues include our unredeemed stored value card liability and unredeemed Stars associated with our loyalty program. The beginning balances of fiscal 2019 current and long-term deferred revenue related to our stored value card and loyalty program were $906.6 million and $64.0 million, respectively. The balance of current and long-term deferred revenue related to our stored value card and loyalty program was $1.1 billion and $73.6 million, respectively, as of March 31, 2019. Disaggregation of Revenues Revenues disaggregated by segment, product type and geographic area are disclosed in Note 15, Segment Reporting.

| Acquisitions and Divestitures | Acquisitions, Divestitures and Strategic Alliance Fiscal 2019 In the second quarter of fiscal 2019, we sold our company-operated retail businesses in France and the Netherlands to Alsea, S.A.B. de C.V. converting these operations to fully licensed markets. These transactions did not have a material impact to our condensed consolidated financial statements. Fiscal 2018 We entered into an agreement on May 6, 2018 to establish the Global Coffee Alliance with Nestlé. On August 26, 2018, we licensed the rights to market, sell and distribute Starbucks consumer packaged goods and foodservice products in authorized channels to Nestlé. We received an upfront payment of approximately $7 billion consisting primarily of prepaid royalties which was recorded as current and long-term deferred revenue. See Note 2, Revenue Recognition, for the accounting treatment. On March 23, 2018, we sold our company-operated retail business in Brazil to SouthRock converting these operations to a fully licensed market. This transaction did not have a material impact to our condensed consolidated financial statements. 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 and 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 condensed consolidated statements of earnings in fiscal 2018. 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 net gain resulting from divestiture of certain operations on our condensed consolidated statements of earnings.

| Derivative Financial Instruments | Derivative Financial Instruments Interest Rates We are subject to interest rate volatility relating to our debt issuances. From time to time, we enter into swap agreements and treasury locks 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 and treasury locks 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 statements of earnings. Refer to Note 9, 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 6, 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. Gains and losses on derivative contracts and foreign currency-denominated debt designated as hedging instruments included in AOCI and expected to be reclassified into earnings within 12 months, net of tax (in millions):

| Inventories | Inventories (in millions):
Other merchandise held for sale includes, among other items, serveware, food and tea. Inventory levels vary due to seasonality, commodity market supply and price fluctuations. As of March 31, 2019, we had committed to purchasing green coffee totaling $1.0 billion under fixed-price contracts and an estimated $278 million under price-to-be-fixed contracts. As of March 31, 2019, 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.

Impact of reclassifications from AOCI on the consolidated statements of earnings (in millions):
In addition to 2.4 billion shares of authorized common stock with $0.001 par value per share, the Company has authorized 7.5 million shares of preferred stock, none of which was outstanding as of March 31, 2019. In September 2018, we entered into accelerated share repurchase agreements (“ASR agreements”) with third-party financial institutions totaling $5.0 billion, effective October 1, 2018. We made a $5.0 billion upfront payment to the financial institutions and received an initial delivery of 72.0 million shares. In March 2019, we received an additional 4.9 million shares upon the completion of the program based on a volume-weighted average share price (less discount) of $65.03. In March 2019, we entered into ASR agreements with third-party financial institutions totaling $2.0 billion, effective March 22, 2019. We made a $2.0 billion upfront payment to the financial institutions and received an initial delivery of 22.2 million shares of our common stock, which approximated 80 percent of the total value based on our share price of $71.96 at the inception of the agreement. Upon completion, the total shares repurchased will be based on the volume-weighted average share price during the term of the ASR agreements less an applicable discount. The financial institutions may be required to deliver additional shares or, under certain circumstances, we may elect to deliver shares or make a cash payment to the financial institutions. Final settlement is expected to be completed no later than June 2019. Outside of the ASR agreements noted above, we repurchased 10.2 million shares of common stock for $713.2 million on the open market during the two quarters ended March 31, 2019. In connection with the ASR agreements and other open market transactions, we repurchased 109.3 million shares of common stock at a total cost of $7.7 billion for the two quarters ended March 31, 2019. During the same period of fiscal 2018, we repurchased 55.9 million shares at a total cost of $3.2 billion. In the first quarter 2019, we announced that our Board of Directors approved an increase of 120 million shares to our ongoing share repurchase program. As of March 31, 2019, 59.5 million shares remained available for repurchase under current authorizations. During the second quarter of fiscal 2019, our Board of Directors declared a quarterly cash dividend to shareholders of $0.36 per share to be paid on May 24, 2019 to shareholders of record as of the close of business on May 9, 2019.

| 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. The tax rate for fiscal 2019 and future years was reduced to 21% from our blended 24.5% in fiscal 2018. In the first quarter of fiscal 2019 the measurement period related to the Tax Act concluded, which resulted in immaterial adjustments to our provisional estimates. In the first quarter of fiscal 2019, we revised our indefinite reinvestment assertions for prior years' earnings from certain foreign subsidiaries. This change did not have a material impact to our financial results. In foreign subsidiaries in which we are partially indefinitely reinvested, the gross taxable temporary difference between its accounting basis and tax basis is approximately $1.3 billion, for which there could be up to approximately $300 million of unrecognized tax liability. While the Tax Act provides for a modified territorial tax system, global intangible low-taxed income (“GILTI”) provisions are applied providing an incremental tax on foreign income. We have made an accounting policy election to treat taxes due under the GILTI provision as a current period expense.

| 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 brewed coffee. The lawsuit is Council for Education and Research on Toxics v. Starbucks Corporation, et al.. On May 9, 2011, the Plaintiff 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 packaged coffee. The lawsuit is Council for Education and Research on Toxics v. Brad Barry LLC, et al.. Both cases have since been consolidated and now include nearly eighty defendants, which constitute the great majority of the coffee industry in California. Plaintiff alleges that the Company and the other defendants failed to provide warnings for their coffee products of exposure to the chemical acrylamide as required under California Health and Safety Code section 25249.5, 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 of coffee products, 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 May 7, 2018, the trial court issued a ruling adverse to defendants on the Phase 2 defense, the Company's last remaining defense to liability. On June 22, 2018, the California Office of Environmental Health Hazard Assessment (OEHHA) proposed a new regulation clarifying that cancer warnings are not required for coffee under Proposition 65. The case was set to proceed to a third phase trial on damages, remedies and attorneys' fees on October 15, 2018. However, on October 12, 2018, the California Court of Appeal granted the defendants request for a stay of the Phase 3 trial. At this stage of the proceedings, Starbucks believes that the likelihood that the Company will ultimately incur a loss in connection with this litigation is reasonably possible rather than probable. Accordingly, no loss contingency was recorded for this matter. The outcome and the financial impact of the case to Starbucks, 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.

| Accounting Policies [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Recent Accounting Pronouncements | Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements In the first quarter of fiscal 2019, we adopted the Financial Accounting Standards Board (“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 primary impact of the adoption was an increase to deferred income taxes, net of $227.6 million and a corresponding cumulative adjustment to opening retained earnings at the beginning of fiscal 2019. In the first quarter of fiscal 2019, we adopted the new guidance on revenue recognition utilizing the modified retrospective method, which primarily changed the accounting method and classification of revenue recognition related to unredeemed stored value cards, referred to as stored value card breakage. Under this new guidance, expected breakage amounts must be recognized proportionately in earnings as redemptions occur. Previously, stored value card breakage was recorded to interest income and other, net utilizing the remote method. Starting in the first quarter of 2019, stored value card breakage was recorded in the revenue lines where stored value cards may be redeemed—primarily company-operated and licensed store revenues. The cumulative impact to retained earnings as of October 1, 2018 was $268.0 million. Impact of adoption on our consolidated balance sheet at September 30, 2018:
Due to the adoption, we began classifying stored value card liabilities as current and long-term deferred revenue. See Note 2, Revenue Recognition, for further discussion of classification of impacts of the adoption. Recent Accounting Pronouncements Not Yet Adopted In February 2018, the 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 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 do not expect a material impact upon adoption of this guidance. In August 2017, the FASB amended its guidance on the accounting for 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 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 do not expect this guidance to have a material impact to our consolidated financial statements and may elect to adopt during the second half 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 be effective at the beginning of our first quarter of fiscal 2020, with optional practical expedients. As permitted by the alternative method issued by the FASB, we will be applying the guidance at the beginning of the year of adoption. 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. Revision of Previously Issued Financial Statements We have revised our condensed consolidated statement of comprehensive income and the related footnotes for the quarter and two quarters ended April 1, 2018 to reflect the correction of an immaterial error primarily related to the reclassification of gains and losses resulting from cash flow hedges from accumulated other comprehensive income to net income. Total other comprehensive income was not changed.
