Accounting Policies [Abstract]  
Basis of presentation
Basis of presentation
The Consolidated Financial Statements include all subsidiaries in which the Company holds a controlling interest. The Company uses the equity-method of accounting for equity investments in less than majority-owned companies if the investment provides the ability to exercise significant influence. All intercompany transactions have been eliminated.

The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”) requires management to use judgment in the application of accounting policies, including making estimates and assumptions. The Company bases its estimates on the information available at the time, its experiences and various other assumptions believed to be reasonable under the circumstances including estimates of the impact of COVID-19. The extent to which COVID-19 impacts the Company’s business and financial results will depend on numerous evolving factors discussed throughout this Annual Report on Form 10-K including, but not limited to, the severity and duration of COVID-19, the extent to which it will impact our customers, team members, suppliers, vendors, business partners and distribution channels. The Company assessed certain accounting matters that require consideration of estimates and assumptions in context with the information reasonably available to the Company and the unknown future impacts of COVID-19 as of August 31, 2020 and through the date of this report. The accounting matters assessed included, but were not limited to, the Company’s carrying value of goodwill, intangible and other long-lived assets including operating lease right-of-use assets. These estimates and assumptions, including the severity and duration of COVID-19, resulted in a material impact to the Company’s consolidated financial statements as of and for the fiscal year ended August 31, 2020. Refer to note 6, goodwill and other intangible assets for details. The Company’s future assessment of the magnitude and duration of COVID-19, as well as other factors, could result in material impacts to the Company’s consolidated financial statements in future reporting periods. Adjustments may be made in subsequent periods to reflect more current estimates and assumptions about matters that are inherently uncertain. Actual results may differ.

The COVID-19 pandemic has severely impacted the economies of the U.S., the UK and other countries around the world. The impact of COVID-19 on the Company’s businesses, financial position, results of operations and cash flows for the fiscal year ended August 31, 2020, as well as information regarding certain expected or potential impacts of COVID-19 on the Company, is discussed throughout this Annual Report on Form 10-K.

The impact of COVID-19, the influence of certain holidays, seasonality, foreign currency rates, changes in vendor, payer and customer relationships and terms, strategic transactions including acquisitions, changes in laws and general economic conditions in the markets in which the Company operates and other factors on the Company’s operations and net earnings for any period may not be comparable to the same period in previous years.
Certain amounts in the Consolidated Financial Statements and associated notes may not add due to rounding. Percentages have been calculated using unrounded amounts for all periods presented.
Cash and cash equivalents
Cash and cash equivalents
Cash and cash equivalents include cash on hand and highly liquid investments with an original maturity of three months or less. Credit and debit card receivables, which generally settle within one to seven business days, of $101 million and $90 million were included in cash and cash equivalents at August 31, 2020 and 2019, respectively.
Restricted cash and other cash flows from operating activities
Restricted cash and other cash flows from operating activities
Restricted cash
The Company is required to maintain cash deposits with certain banks which consist of deposits restricted under contractual agency agreements and cash restricted by law and other obligations.
Accounts receivable
Accounts receivable
Accounts receivable are stated net of allowances for doubtful accounts. Accounts receivable balances primarily consist of trade receivables due from customers, including amounts due from third-party payers (e.g., pharmacy benefit managers, insurance companies and governmental agencies), clients and members. Trade receivables were $6.0 billion and $6.0 billion at August 31, 2020 and 2019, respectively. Other accounts receivable balances, which consist primarily of receivables from vendors and manufacturers, including receivables from AmerisourceBergen (see note 18, related parties), were $1.2 billion and $1.2 billion at August 31, 2020 and 2019, respectively.
Charges to allowance for doubtful accounts are based on estimates of recoverability using both historical write-offs and specifically identified receivables.
Inventories
Inventories
The Company values inventories on a lower of cost and net realizable value or market basis. Inventories include product costs, inbound freight, direct labor, warehousing costs for retail pharmacy operations and distribution of products and vendor allowances not classified as a reduction of advertising expense.

The Company’s Retail Pharmacy USA segment inventory is accounted for using the last-in-first-out (“LIFO”) method. The total carrying value of the segment inventory accounted for under the LIFO method was $6.4 billion and $6.6 billion at August 31, 2020 and 2019, respectively. At August 31, 2020 and 2019, Retail Pharmacy USA segment inventory would have been greater by $3.3 billion and $3.2 billion, respectively, if they had been valued on a lower of first-in-first-out (“FIFO”) cost and net realizable value.
The Company’s Retail Pharmacy International and Pharmaceutical Wholesale segments’ inventory is primarily accounted for using the FIFO method.
Property, plant and equipment
Property, plant and equipment
Property, plant and equipment are stated at cost less accumulated depreciation. Major repairs, which extend the useful life of an asset, are capitalized; routine maintenance and repairs are charged against earnings. Depreciation is provided on a straight-line basis over the estimated useful lives of owned assets. Leasehold improvements, equipment under finance lease and finance lease properties are amortized over their respective estimate of useful life or over the term of the lease, whichever is shorter. The majority of the Company’s fixtures and equipment uses the composite method of depreciation. The following table summarizes the Company’s property, plant and equipment (in millions) and estimated useful lives (in years):

The Company capitalizes application development stage costs for internally developed software. These costs are amortized over a three to ten year period.
Leases
Leases
The Company determines if an arrangement contains a lease at the inception of a contract. The lease classification is determined at the commencement date. Right-of-use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease during the lease term. Right-of-use assets and lease liabilities are recognized at the commencement date based on the present value of the remaining future minimum lease payments during the lease term. The commencement date of all lease terms is the earlier of the date the Company becomes legally obligated to make rent payments or the date the Company has the right to control the property. The Company utilizes its incremental borrowing rate to discount the lease payments. The incremental borrowing rate is based on the Company's estimated rate of interest for a collateralized borrowing over a similar term as the lease term. The operating lease right-of-use assets also include lease payments made before commencement, lease incentives and are recorded net of impairment. Operating leases are expensed on a straight line basis over the lease term.

Initial terms for leased premises in the United States are typically 15 to 25 years, followed by additional terms containing renewal options at five-year intervals, and may include rent escalation clauses. Non-U.S. leases are typically for shorter terms and may include cancellation clauses or renewal options. The lease term of real estate leases includes renewal options that are reasonably certain of being exercised. Options to extend are considered reasonably certain of being exercised based on evaluation if there is significant investments within the leased property which have useful lives greater than the non-cancelable lease term, performance of the underlying store and the Company’s economic and strategic initiatives. Short-term leases with an initial term of 12 months or less are not recorded on the balance sheets.

The Company accounts for lease components and non-lease components as a single lease component. Variable lease payment amounts that cannot be determined at the commencement of the lease such as increases in lease payments based on changes in index rates or usage, are not included in the right-of-use assets or lease liabilities. These are expensed as incurred. The Company has real estate leases which require additional payments based on sales volume, as well as reimbursement for real estate taxes, common area maintenance and insurance, which are expensed as incurred as variable lease costs and hence are not included in the lease payments used to calculate lease liability. Other real estate leases contain one fixed lease payment that includes real estate taxes, common area maintenance and insurance. These fixed payments are considered part of the lease payment and included in the right-of-use assets and lease liabilities. The Company does not separately account for the land portion of the leases involving land and building.

Finance leases are recognized within property, plant and equipment and as a finance lease liability within accrued expenses and other liabilities and other noncurrent liabilities.
Business combinations
Business combinations
The Company allocates the fair value of purchase consideration to the tangible and intangible assets purchased and the liabilities assumed on the basis of their fair values at the date of acquisition. The determination of fair values of assets acquired and liabilities assumed requires estimates and the use of valuation techniques when a market value is not readily available. Any
excess of purchase price over the fair value of net tangible and intangible assets acquired is allocated to goodwill. If the Company obtains new information about facts and circumstances that existed as of the acquisition date during the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the assets acquired and liabilities assumed.
Goodwill and indefinite-lived intangible assets
Goodwill and indefinite-lived intangible assets
Goodwill represents the excess of the purchase price over the fair value of assets acquired and liabilities assumed in business combinations. Acquired intangible assets are recorded at fair value.

Goodwill and indefinite-lived intangible assets are evaluated for impairment annually during the fourth quarter, or more frequently if an event occurs or circumstances change that could more likely than not reduce the fair value of a reporting unit or intangible asset below its carrying value. As part of the Company’s impairment analysis, fair value of a reporting unit is determined using both the income and market approaches. The income approach requires management to estimate a number of factors for each reporting unit, including projected future operating results, economic projections, anticipated future cash flows and discount rates. The market approach estimates fair value using comparable marketplace fair value data from within a comparable industry grouping. Indefinite-lived intangible assets are tested for impairment by comparing the estimated fair value of the asset to its carrying value. If the carrying value of the asset exceeds its estimated fair value, an impairment loss is recognized and the asset is written down to its estimated fair value
Equity method investments
Equity method investments
The Company uses the equity method of accounting for equity investments if the investment provides the ability to exercise significant influence, but not control, over operating and financial policies of the investee. The Company’s proportionate share of the net income or loss of these investees is included in consolidated net earnings. Judgment regarding the level of influence over each equity method investment includes considering key factors such as the Company’s ownership interest, legal form of the investee (e.g. limited liability partnership), representation on the board of directors, participation in policy-making decisions and material intra-entity transactions.
The Company evaluates equity method investments for impairment whenever events or changes in circumstances indicate that the carrying amount of the investment might not be recoverable. Factors considered by the Company when reviewing an equity method investment for impairment include the length of time (duration) and the extent (severity) to which the fair value of the equity method investment has been less than cost, the investee’s financial condition and near-term prospects and the intent and ability to hold the investment for a period of time sufficient to allow for anticipated recovery. An impairment that is other-than-temporary is recognized in the period identified.
Financial instruments
Financial instruments
The Company uses derivative instruments to hedge its exposure to interest rate and currency risks arising from operating and financing activities. In accordance with its risk management policies, the Company does not hold or issue derivative instruments for trading or speculative purposes.

Derivatives are recognized on the Consolidated Balance Sheets at their fair values. When the Company becomes a party to a derivative instrument and intends to apply hedge accounting, it formally documents the hedge relationship and the risk management objective for undertaking the hedge which includes designating the instrument for financial reporting purposes as a fair value hedge, a cash flow hedge, or a net investment hedge. The accounting for changes in fair value of a derivative instrument depends on whether the Company had designated it in a qualifying hedging relationship and on the type of hedging relationship. The Company applies the following accounting policies:

Changes in the fair value of a derivative designated as a fair value hedge, along with the gain or loss on the hedged asset or liability attributable to the hedged risk, are recorded in the Consolidated Statements of Earnings in the same line item, generally interest expense, net.
Changes in the fair value of a derivative designated as a cash flow hedge are recorded in accumulated other comprehensive income (loss) in the Consolidated Statements of Comprehensive Income and reclassified into earnings in the period or periods during which the hedged item affects earnings and is presented in the same line item as the earnings effect of the hedged item.
Changes in the fair value of a derivative designated as a hedge of a net investment in a foreign operation are recorded in cumulative translation adjustments within accumulated other comprehensive income (loss) in the Consolidated Statements of Comprehensive Income. Recognition in earnings of amounts previously recorded in cumulative translation adjustments is limited to circumstances such as complete or substantially complete liquidation of the net investment in the hedged investments in foreign operations.
Changes in the fair value of a derivative not designated in a hedging relationship are recognized in the Consolidated Statements of Earnings.
Cash receipts or payments on a settlement of a derivative contract are reported in the Consolidated Statements of Cash Flows consistent with the nature of the underlying hedged item.

For derivative instruments designated as hedges, the Company assesses, both at the hedge’s inception and on an ongoing basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in fair values or cash flows of hedged items. Highly effective means that cumulative changes in the fair value of the derivative are between 80% and 125% of the cumulative changes in the fair value of the hedged item. In addition, when the Company determines that a derivative is not highly effective as a hedge, hedge accounting is discontinued. When it is probable that a hedged forecasted transaction will not occur, the Company discontinues hedge accounting for the affected portion of the forecasted transaction and reclassifies any gains or losses in accumulated other comprehensive income (loss) to earnings in the Consolidated Statement of Earnings. When a derivative in a hedge relationship is terminated or the hedged item is sold, extinguished or terminated, hedge accounting is discontinued prospectively.
Pension and postretirement benefits
Pension and postretirement benefits
The Company has various defined benefit pension plans that cover some of its non-U.S. employees. The Company also has a postretirement healthcare plan that covers qualifying U.S. employees. Eligibility and the level of benefits for these plans vary depending on participants’ status, date of hire and or length of service. Pension and postretirement plan expenses and valuations are dependent on assumptions used by third-party actuaries in calculating those amounts. These assumptions include discount rates, healthcare cost trends, long-term return on plan assets, retirement rates, mortality rates and other factors.
The Company funds its pension plans in accordance with applicable regulations. The Company records the service cost component of net pension cost and net postretirement benefit cost in selling, general and administrative expenses. The Company records all other net cost components of net pension cost and net postretirement benefit cost in other income (expense). The postretirement healthcare plan is not funded.
Noncontrolling interests Noncontrolling interestsThe Company presents noncontrolling interests as a component of equity on its Consolidated Balance Sheets and reports the portion of its earnings or loss for noncontrolling interest as net earnings attributable to noncontrolling interests in the Consolidated Statements of Earnings
Currency
Currency
Assets and liabilities of non-U.S. dollar functional currency operations are translated into U.S. dollars at end-of-period exchange rates while revenues, expenses and cash flows are translated at average monthly exchange rates over the period. Equity is translated at historical exchange rates and the resulting cumulative translation adjustments are included as a component of accumulated other comprehensive income (loss) in the Consolidated Balance Sheets.

Assets and liabilities not denominated in the functional currency are remeasured into the functional currency at end-of-period exchange rates, except for nonmonetary balance sheet amounts, which are remeasured at historical exchange rates. Revenues and expenses are recorded at average monthly exchange rates over the period, except for those expenses related to nonmonetary balance sheet amounts, which are remeasured at historical exchange rates. Gains or losses from foreign currency remeasurement are generally included in selling, general and administrative expenses within the Consolidated Statements of Earnings.
Commitments and contingencies
Commitments and contingencies
On a quarterly basis, the Company assesses its liabilities and contingencies for outstanding legal proceedings and reserves are established on a case-by-case basis for those legal claims for which management concludes that it is probable that a loss will be incurred and that the amount of such loss can be reasonably estimated. Substantially all of these contingencies are subject to significant uncertainties and, therefore, determining the likelihood of a loss and/or the measurement of any loss can be complex.
With respect to litigation and other legal proceedings where the Company has determined that a loss is reasonably possible, the Company may be unable to estimate the amount or range of reasonably possible loss due to the inherent difficulty of predicting the outcome of and uncertainties regarding such litigation and legal proceedings. The Company’s assessments are based on estimates and assumptions that have been deemed reasonable by management, but that may prove to be incomplete or inaccurate, and unanticipated events and circumstances may occur that might cause the Company to change those estimates and assumptions. Therefore, it is possible that an unfavorable resolution of one or more pending litigation or other contingencies could have a material adverse effect on the Company’s Consolidated Financial Statements in a future fiscal period. Management’s assessment of current litigation and other legal proceedings, including the corresponding accruals, could change because of the discovery of facts with respect to legal actions or other proceedings pending against the Company which are not presently known. Adverse rulings or determinations by judges, juries, governmental authorities or other parties could also result in changes to management’s assessment of current liabilities and contingencies. Accordingly, the ultimate costs of resolving these claims may be substantially higher or lower than the amounts reserved.
Revenue recognition, Loyalty programs and gift card, Cost of sales
Revenue recognition
Sales are recognized at an amount that reflects the consideration to which the Company expects to be entitled in exchange for transferring control of goods or services to the customer. Sales are reported on the gross amount billed to a customer less discounts if it has earned revenue as a principal from the sale of goods and services. Sales are reported on the net amount retained (that is, the amount billed to the customer less the amount paid to a vendor) if it has earned a commission or a fee as an agent.

Retail Pharmacy USA and Retail Pharmacy International
The Company recognizes revenue, net of taxes and expected returns, at the time it sells merchandise or dispenses prescription drugs to the customer. The Company estimates revenue based on expected reimbursements from third-party payers (e.g., pharmacy benefit managers, insurance companies and governmental agencies) for dispensing prescription drugs. The estimates are based on all available information including historical experience and are updated to actual reimbursement amounts.

Pharmaceutical Wholesale
Wholesale revenue is recognized, net of taxes and expected returns, upon shipment of goods, which is generally also the day of delivery.

Loyalty programs and gift cards
The Company’s loyalty rewards programs represent a separate performance obligation and are accounted for using the deferred revenue approach. When goods are sold, the transaction price is allocated between goods sold and loyalty points awarded based upon the relative standalone selling price. The revenue allocated to the loyalty points is recognized upon redemption. Loyalty programs breakage is recognized as revenue based on the redemption pattern.

Customer purchases of gift cards are not recognized as revenue until the card is redeemed. Gift card breakage (i.e., unused gift card) is recognized as revenue based on the redemption pattern.

Cost of sales
Cost of sales includes the purchase price of goods and cost of services rendered, store and warehouse inventory loss, inventory obsolescence and supplier rebates. In addition to product costs, cost of sales includes warehousing costs for retail operations, purchasing costs, freight costs, cash discounts and vendor allowances.

Vendor allowances and supplier rebates
Vendor allowances are principally received as a result of purchases, sales or promotion of vendors’ products. Allowances are generally recorded as a reduction of inventory and are recognized as a reduction of cost of sales when the related merchandise is sold. Allowances received for promoting vendors’ products are offset against advertising expense and result in a reduction of selling, general and administrative expenses to the extent of advertising costs incurred, with the excess treated as a reduction of inventory costs.

Rebates or refunds received by the Company from its suppliers, mostly in cash, are considered as an adjustment of the prices of the supplier’s products purchased by the Company.
Selling, general and administrative expenses
Selling, general and administrative expenses
Selling, general and administrative expenses mainly consist of salaries and employee costs, occupancy costs, depreciation and amortization, credit and debit card fees and expenses directly related to stores. In addition, other costs included are headquarters’ expenses, advertising costs (net of vendor advertising allowances), wholesale warehousing costs and insurance.
Advertising costs
Advertising costs
Advertising costs, which are reduced by the portion funded by vendors, are expensed as incurred or when services have been received. Net advertising expenses, which are included in selling, general and administrative expenses, were $534 million in fiscal 2020, $585 million in fiscal 2019 and $665 million in fiscal 2018.
Impairment of long-lived assets
Impairment of long-lived assets
The Company evaluates the recoverability of long-lived assets whenever events or changes in circumstances indicate that the carrying value of such an asset may not be recoverable. The evaluation of long-lived assets is performed at the lowest level of identifiable cash flows. Long-lived assets related to the Company’s retail operations include property, plant and equipment, definite-lived intangibles, right of use asset as well as operating lease liability. If the asset group fails the recoverability test, then an impairment charge is determined based on the difference between the fair value of the asset group compared to its carrying value. Fair value of the asset group is generally determined using income approach based on cash flows expected from the use and eventual disposal of the asset group.
Stock compensation plans Stock compensation plansStock based compensation is measured at fair value at the grant date. The Company grants stock options, performance shares and restricted units to the Company’s non-employee directors, officers and employees. The Company recognizes compensation expense on a straight-line basis over the substantive service period.
Insurance
Insurance
The Company obtains insurance coverage for catastrophic exposures as well as those risks required by law to be insured. In general, the Company’s U.S. subsidiaries retain a significant portion of losses related to workers’ compensation, property, comprehensive general, pharmacist and vehicle liability, while non-U.S. subsidiaries manage their exposures through insurance coverage with third-party carriers. Management regularly reviews the probable outcome of claims and proceedings, the expenses expected to be incurred, the availability and limits of the insurance coverage and the established accruals for liabilities. Liabilities for losses are recorded based upon the Company’s estimates for both claims incurred and claims incurred but not reported. The provisions are estimated in part by considering historical claims experience, demographic factors and other actuarial assumptions.
Income taxes
Income taxes
The Company accounts for income taxes according to the asset and liability method. Under this method, deferred tax assets and liabilities are recognized based upon the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured pursuant to tax laws using rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rate is recognized in income in the period that includes the enactment date. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts more likely than not to be realized.

In determining the provision for income taxes, the Company uses income, permanent differences between book and tax income, the relative proportion of foreign and domestic income, enacted statutory income tax rates, projections of income subject to Subpart F rules and unrecognized tax benefits related to current year results. Discrete events such as the assessment of the ultimate outcome of tax audits, audit settlements, recognizing previously unrecognized tax benefits due to lapsing of the applicable statute of limitations, recognizing or de-recognizing benefits of deferred tax assets due to future year financial statement projections and changes in tax laws are recognized in the period in which they occur.

The Company is subject to routine income tax audits that occur periodically in the normal course of business. U.S. federal, state, local and foreign tax authorities raise questions regarding the Company’s tax filing positions, including the timing and amount of deductions and the allocation of income among various tax jurisdictions. In evaluating the tax benefits associated
with the various tax filing positions, the Company records a tax benefit for uncertain tax positions using the highest cumulative tax benefit that is more likely than not to be realized. Adjustments are made to the liability for unrecognized tax benefits in the period in which the Company determines the issue is effectively settled with the tax authorities, the statute of limitations expires for the return containing the tax position or when more information becomes available.
Earnings per share Earnings per shareThe dilutive effect of outstanding stock options on earnings per share is calculated using the treasury stock method. Stock options are anti-dilutive and excluded from the earnings per share calculation if the exercise price exceeds the average market price of the common shares.

Adoption of new accounting pronouncements
Financial instruments - hedging and derivatives
In October 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-16, Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (“SOFR”) Overnight Index Swap (“OIS”) Rate as Benchmark Interest Rate for Hedge Accounting Purposes. This ASU permits use of the OIS rate based on the SOFR as a U.S. benchmark interest rate for hedge accounting purposes. The Company adopted this new accounting standard on September 1, 2019 on a prospective basis. The adoption of this ASU had no impact on the Company’s results of operations, cash flows or financial position.

Intangibles – goodwill and other – internal-use software
In August 2018, the FASB issued ASU 2018-15, Intangibles-Goodwill and Other- Internal-Use Software (Subtopic 350-40). This ASU addresses customer’s accounting for implementation costs incurred in a cloud computing arrangement that is a service contract and also adds certain disclosure requirements related to implementation costs incurred for internal-use software and cloud computing arrangements. The amendment aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The Company early adopted this new accounting standard on September 1, 2019 on a prospective basis. The adoption of this ASU did not have a material impact on the Company’s results of operations or financial position.

Contributions made
In June 2018, the FASB issued ASU 2018-08, Clarifying the Scope and the Accounting Guidance for Contributions Received and Contributions Made (Topic 958). This ASU clarifies and improves guidance about whether a transfer of assets (or reduction of liabilities) is a contribution or an exchange transaction, and whether a contribution is conditional. The ASU applies to all entities, including business entities, that receive or make contributions of cash or other assets, including promises to give. The Company adopted this new accounting standard on September 1, 2019 on a prospective basis. The adoption of this ASU did not have a material impact on the Company’s results of operations or financial position.

Compensation – stock compensation
In June 2018, the FASB issued ASU 2018-07, Compensation-Stock Compensation (Topic 718). This ASU eliminated most of the differences between accounting guidance for share-based compensation granted to nonemployees and the guidance for share-based compensation granted to employees. The ASU supersedes the guidance for nonemployees and expands the scope of the guidance for employees to include both. The Company adopted this new accounting standard on September 1, 2019. The adoption of this ASU had no impact on the Company’s results of operations, cash flows or financial position.

Accounting for reclassification of certain tax effects from accumulated other comprehensive income
In February 2018, the FASB issued ASU 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This ASU addresses the income tax effects of items in accumulated other comprehensive income (“AOCI”) which were originally recognized in other comprehensive income, rather than in income from continuing operations. Specifically, it permits a reclassification from AOCI to retained earnings for the adjustment of deferred taxes due to the reduction of the historical corporate income tax rate to the newly enacted corporate income tax rate resulting from the U.S. tax law changes enacted in December 2017. It also requires certain disclosures about these reclassifications. The Company adopted this new accounting standard on September 1, 2019 on a prospective basis. The Company elected not to reclassify the income tax effects of change in historical corporate tax rate from AOCI to retained earnings. The adoption of this ASU had no impact on the Company’s results of operations, cash flows or financial position.
Leases
In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which supersedes Topic 840, Leases. Subsequently, the FASB issued additional ASUs which further clarify this guidance. This ASU increases the transparency and comparability of organizations by requiring the capitalization of substantially all leases on the balance sheet and disclosures of key information about leasing arrangements. Under this new guidance, at the lease commencement date, a lessee recognizes a right-of-use asset and lease liability, which is initially measured at the present value of the future lease payments. For income statement purposes, a dual model was retained for lessees, requiring leases to be classified as either operating or finance leases. Under the operating lease model, lease expense is recognized on a straight-line basis over the lease term. Under the finance lease model, interest on the lease liability is recognized separately from amortization of the right-of-use asset. In addition, a new ASU was issued in July 2018, to provide relief to companies from restating the comparative periods.

The Company adopted this new accounting standard on September 1, 2019 on a modified retrospective basis and applied the new standard to all leases through a cumulative-effect adjustment to beginning retained earnings. As a result, comparative financial information has not been restated and continues to be reported under the accounting standards in effect for those periods. The Company elected the package of practical expedients permitted under the transition guidance, which among other things, allows the carryforward of historical lease classification. The adoption of this new accounting standard resulted in recognition of lease liabilities of $24 billion and recognition of right-of-use assets of $22 billion net of liabilities for facility closing, deferred rent, favorable lease interest intangible asset, unfavorable lease interest liability, lease incentives and prepaid rent as of August 31, 2019. The adoption also resulted in a decrease to retained earnings of $0.4 billion due to transition date impairment of right-of-use assets related to previously impaired long-lived assets of $0.8 billion, net of tax, partially offset by de-recognition of deferred gains on historical sale-leaseback transactions of $0.4 billion, net of tax. See note 4. Leases for further information.

The impact to the Company's opening Consolidated Balance Sheets as of September 1, 2019 was as follows (in millions):

According to the guidance provided in the FASB staff Q&A Topic 842 Leases – Accounting for lease concessions related to the effects of COVID-19, released on April 2020, the Company elected to account for certain lease concessions related to COVID-19 as a reduction to rent expense for the period. During the fiscal year ended August 31, 2020, these rent concessions related to COVID-19 were not material.

Effects of Reference Rate Reform on Financial Reporting
In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This ASU provides optional expedient and exceptions for applying generally accepted accounting principles to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. In response to the concerns about structural risks of interbank offered rates ("IBORs") and, particularly, the risk of cessation of the London Interbank Offered Rate ("LIBOR"), regulators in several jurisdictions around the world have undertaken reference rate reform initiatives to identify alternative reference rates that are more observable or transaction based and less susceptible to manipulation. The ASU provides companies with optional guidance to ease the potential accounting burden associated with transitioning away from reference rates that are expected to be discontinued. The ASU can be adopted no later than December 1, 2022 (fiscal 2023) with early adoption permitted. The Company is evaluating the effect of adopting this new accounting guidance.

Financial Instruments
In March 2020, FASB issued ASU 2020-03. This ASU improves and clarifies various financial instruments topics, including the current expected credit losses ("CECL") standard issued in 2016. The ASU includes seven different issues that describe the areas of improvement and the related amendments to GAAP, intended to make the standards easier to understand and apply by eliminating inconsistencies and providing clarifications. The amendments have different effective dates. The Company is evaluating the effect of adopting this new accounting guidance, but does not expect adoption will have a material impact on the Company’s financial statements.

Investments - equity securities; Investments—Equity Method and Joint Ventures; Derivatives and Hedging
In January 2020, the FASB issued ASU 2020-01, Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815). The amendments in this ASU clarify the interaction between the accounting for investments in equity securities, investment in equity method and certain derivatives instruments. The ASU is expected to reduce diversity in practice and increase comparability of the accounting for these interactions. This ASU is effective for fiscal years beginning after December 15, 2021 (fiscal 2023). The adoption of this ASU is not expected to have any impact on the Company's results of operations, cash flows or financial position.

Income taxes - simplifying the accounting for income taxes
In December 2019, the FASB issued ASU 2019-12: Simplifying the Accounting for Income Taxes (Topic 740), which removes certain exceptions to the general principles in Topic 740 and improves consistent application of and simplifies GAAP for other areas of Topic 740 by clarifying and amending existing guidance. This ASU is effective for fiscal years beginning after December 15, 2020 (fiscal 2022), and interim periods within those fiscal years, with early adoption permitted. The Company is evaluating the effect of adopting this new accounting guidance but does not expect adoption will have a material impact on the Company's disclosures.

Investments - equity securities
In April 2019, the FASB issued ASU 2019-04, Codification Improvements to Financial Instruments-Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Financial Instruments (Topic 825). This extensive ASU provides clarifications for three topics related to financial instruments accounting, some of which apply to the Company. For example, this ASU clarifies the disclosure requirements that apply to equity securities without a readily determinable fair value for which the measurement alternative is elected. This ASU is effective for fiscal years beginning after December 15, 2019 (fiscal 2021). The adoption of this ASU is not expected to have a significant impact on the Company's results of operations, cash flows or financial position.

Collaborative arrangements
In November 2018, the FASB issued ASU 2018-18, Collaborative Arrangements (Topic 808). This ASU clarifies the interaction between Topic 808, Collaborative Arrangements, and Topic 606, Revenue from Contracts with Customers. This ASU is effective for fiscal years beginning after December 15, 2019 (fiscal 2021). The adoption of this ASU is not expected to have a significant impact on the Company’s results of operations, cash flows or financial position.

Compensation – retirement benefits – defined benefit plans
In August 2018, the FASB issued ASU 2018-14, Compensation - Retirement benefits (Topic 715-20). This ASU amends ASC 715 to add, remove and clarify disclosure requirements related to defined benefit pension and other postretirement plans. The ASU eliminates the requirement to disclose the amounts in accumulated other comprehensive income expected to be recognized as part of net periodic benefit cost over the next year. The ASU also removes the disclosure requirements for the effects of a one-percentage-point change on the assumed health care costs and the effect of this change in rates on service cost, interest cost and the benefit obligation for postretirement health care benefits. This ASU is effective for fiscal years ending after December 15, 2020 (fiscal 2021) and must be applied on a retrospective basis. The Company is evaluating the effect of adopting this new
accounting guidance, but does not expect adoption will have a material impact on the Company's financial position.

Fair value measurement
In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820). The ASU eliminates such disclosures as the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy. The ASU adds new disclosure requirements for Level 3 measurements. This ASU is effective for fiscal years beginning after December 15, 2019 (fiscal 2021), and interim periods within those fiscal years, with early adoption permitted for any eliminated or modified disclosures. The Company is evaluating the effect of adopting this new accounting guidance, but does not expect adoption will have a material impact on the Company's disclosures.

Financial instruments - credit losses
In June 2016, the FASB issued ASU 2016-13: Measurement of Credit Losses on Financial Instruments (Topic 326), which amends the Board’s guidance on the impairment of financial instruments. The ASU adds to U.S. GAAP an impairment model that is based on expected losses rather than incurred losses, which is known as the CECL model. The CECL model applies to most debt instruments (other than those measured at fair value), trade and other receivables, financial guarantee contracts, and loan commitments. This ASU is effective for fiscal years beginning after December 15, 2019 (fiscal 2021), and interim periods within those fiscal years, with early adoption permitted. The Company is evaluating the effect of adopting this new accounting guidance, but does not expect adoption will have a material impact on the Company’s financial position or results of operations.
