Summary of major accounting policies (Policies)

12 Months Ended

Aug. 31, 2018

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 experience and various other assumptions believed to be reasonable under the circumstances. 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 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.

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 two to seven business days, of $127 million and $98 million were included in cash and cash equivalents at August 31, 2018 and 2017, respectively.

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 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 $5.4 billion and $5.5 billion at August 31, 2018 and August 31, 2017, respectively. Other accounts receivable balances, which consist primarily of receivables from vendors and manufacturers, including receivables from AmerisourceBergen (see note 17, related parties), were $1.2 billion and $1.1 billion at August 31, 2018 and August 31, 2017, respectively.

Charges to allowance for doubtful accounts are based on estimates of recoverability using both historical write-offs and specifically identified receivables.

Inventories

The Company values inventories on a lower of cost and net realizable value or market. Inventories include product costs, inbound freight, direct labor, warehousing costs for retail pharmacy operations, overhead costs relating to the manufacture 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 $6.7 billion and $5.9 billion at August 31, 2018 and 2017, respectively. At August 31, 2018 and 2017, Retail Pharmacy USA segment inventory would have been greater by $3.0 billion, 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 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 capital lease and capital 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. Therefore, gains and losses on retirement or other disposition of such assets are included in earnings only when an operating location is closed, substantially remodeled or impaired.

The Company capitalizes application development stage costs for internally developed software.

Leases

Initial terms for leased premises in the U.S. 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 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. In addition to minimum fixed rentals, some leases provide for contingent rentals based upon a portion of sales.

Capital leases are recognized within property, plant and equipment and as a capital lease liability within accrued expenses and other liabilities and other non-current liabilities. Operating leases are expensed on a straight line basis over the lease term.

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 other 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 would 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.

Finite-lived intangible assets are amortized on a straight-line basis over their estimated useful lives.

Equity method investments

The Company uses the equity method of accounting for equity investments in companies 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 companies 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, 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

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.

Liabilities for facility closings

The Company provides for future costs related to closed locations. The liability is based on the present value of future rent obligations and other related costs (net of estimated sublease rent) to the first lease option date.

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.

Noncontrolling interests

The 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 Statement of Earnings.

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. For all periods presented, there were no material operational gains or losses from foreign currency transactions.

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

Revenue is recognized when: (i) persuasive evidence of an arrangement exists, (ii) delivery has occurred or services have been rendered, (iii) the seller’s price to the buyer is fixed or determinable and (iv) collectability is reasonably assured. The following revenue recognition policies have been established for the Company’s reportable segments.

Retail Pharmacy USA and Retail Pharmacy International

The Company recognizes revenue, net of taxes and estimated returns, at the time it sells merchandise or dispenses prescription drugs to the customer. Returns are estimated using historical experience. The Company initially 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 historical experience and are updated to actual reimbursement amounts.

Pharmaceutical Wholesale

Wholesale revenue is recognized, net of taxes, upon shipment of goods, which is generally also the day of delivery. When the Company acts in the capacity of an agent or a logistics service provider, revenue is the fee received for the service and is recognized when the services have been performed.

Cost of sales

Cost of sales includes the purchase price of goods and cost of services rendered, store and warehouse inventory loss, inventory obsolescence, manufacturing costs 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.

Loyalty programs

The Company’s loyalty rewards programs are accrued as a charge to cost of sales at the time a point is earned. Points are funded internally and through vendor participation and are credited to cost of sales at the time a vendor-sponsored point is earned. Breakage is recorded as points expire as a result of a member’s inactivity or if the points remain unredeemed after a certain period in accordance with the terms of the loyalty rewards program.

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, which are reduced by the portion funded by vendors, are expensed as incurred or when services have been received.

Impairment of long-lived assets

The Company tests long-lived assets for impairment whenever events or circumstances indicate that a certain asset or asset group may be impaired. Once identified, the amount of the impairment is computed by comparing the carrying value of the assets to the fair value, which is primarily based on the discounted estimated future cash flows.

Stock compensation plans

Stock 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.

Warrants

Until their exercise in fiscal 2016, the warrants to acquire shares of AmerisourceBergen Corporation were accounted for as a derivative under ASC Topic 815, Derivatives and Hedging. The Company reports its warrants at fair value within other non-current assets in the Consolidated Balance Sheets and changes in the fair value of warrants are recognized in other income in the Consolidated Statements of Earnings. A deferred credit from the day-one valuation attributable to the warrants granted to Walgreens was amortized over the life of the warrants.

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

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 bases. Deferred tax assets and liabilities are measured pursuant to tax laws using rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The 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

The 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.

New accounting pronouncements

Adoption of new accounting pronouncements

Accounting for hedging activities

In August 2017, the FASB issued Accounting Standards Update (“ASU”) 2017-12, Derivative and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. This ASU expands an entity’s ability to hedge nonfinancial and financial risk components and reduces complexity in fair value hedges of interest rate risk. It eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. It also eases certain documentation and assessment requirements and modifies the accounting for components excluded from the assessment of hedge effectiveness. This ASU is effective for fiscal years beginning after December 15, 2018 (fiscal 2020), and interim periods within those fiscal years, with early adoption permitted. The Company early adopted this guidance during the third fiscal quarter of 2018. The adoption did not have any impact on the Company’s results of operations, cash flows or financial position.

Measurement of inventory

In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory. This ASU simplifies current accounting treatments by requiring entities to measure most inventories at “the lower of cost and net realizable value” rather than using lower of cost or market. This guidance does not apply to inventories measured using last-in, first-out method or the retail inventory method. This ASU is effective for fiscal years beginning after December 15, 2016 (fiscal 2018), and interim periods within those fiscal years. The Company adopted this guidance on a prospective basis at the beginning of fiscal 2018 and adoption did not have a material impact on the Company’s results of operations, cash flows or financial position.

New accounting pronouncements not yet adopted

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). 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 amendments in this ASU can be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. 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.

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 2022) 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.

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. This ASU is effective for annual periods beginning after December 15, 2018 (fiscal 2020), and interim periods within those years. 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.

Accounting for reclassification of certain tax effects from accumulated other comprehensive income

In February 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“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. This ASU is effective for fiscal years beginning after December 15, 2018 (fiscal 2020), and interim periods within those fiscal years, with early adoption permitted. The new guidance must be applied either on a prospective basis in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in the U.S. federal corporate income tax rate in the U.S. tax law changes are recognized. 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.

Presentation of net periodic pension cost and net periodic postretirement benefit cost

In March 2017, the FASB issued ASU 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This ASU requires an employer to report the service cost component of net periodic pension cost and net periodic postretirement cost in the same line item in the statement of earnings as other compensation costs arising from services rendered by the related employees during the period. The other net cost components are required to be presented in the statement of earnings separately from the service cost component and outside a subtotal of income from operations. Additionally, the line item used in the statement of earnings to present the other net cost components must be disclosed in the notes to the financial statements. This ASU is effective for fiscal years beginning after December 15, 2017 (fiscal 2019), and interim periods within those fiscal years, and must be applied on a retrospective basis. The Company has evaluated the effect of adopting this new accounting guidance and determined that adoption will not have a material impact on the Company’s results of operations. The Company will adopt this new accounting guidance as of September 1, 2018 (fiscal 2019).

Restricted cash

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. This ASU requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the Statement of Cash Flows. This ASU is effective for fiscal years beginning after December 15, 2017 (fiscal 2019), and interim periods within those fiscal years, with early adoption permitted. The new guidance must be applied on a retrospective basis. The Company has evaluated the effect of adopting this new accounting guidance and determined that adoption will not have a material impact on the Company’s Statement of Cash Flows. The Company will adopt this new accounting guidance as of September 1, 2018 (fiscal 2019).

Tax accounting for intra-entity asset transfers

In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory. Topic 740, Income Taxes, prohibits the recognition of current and deferred income taxes for an intra-entity asset transfer until the asset has been sold to an outside party. In addition, interpretations of this guidance have developed in practice for transfers of certain intangible and tangible assets. This prohibition on recognition is an exception to the principle of comprehensive recognition of current and deferred income taxes in GAAP. To more faithfully represent the economics of intra-entity asset transfers, the amendments in this ASU require that entities recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The amendments in this ASU do not change GAAP for the pre-tax effects of an intra-entity asset transfer under Topic 810, Consolidation, or for an intra-entity transfer of inventory. This ASU is effective for fiscal years beginning after December 15, 2017 (fiscal 2019), including interim periods within those fiscal years, with early adoption permitted. The new guidance must be applied on a modified retrospective basis through a cumulative effect adjustment recognized directly to retained earnings as of the date of adoption. The Company has evaluated the effect of adopting this new accounting guidance and determined that adoption will not have a material impact on the Company’s results of operations. The Company will adopt this new accounting guidance as of September 1, 2018 (fiscal 2019).

Classification of certain cash receipts and cash payments

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This ASU addresses the classification of certain specific cash flow issues including debt prepayment or extinguishment costs, settlement of certain debt instruments, contingent consideration payments made after a business combination, proceeds from the settlement of certain insurance claims and distributions received from equity method investees. This ASU is effective for fiscal years beginning after December 15, 2017 (fiscal 2019), and interim periods within those fiscal years, with early adoption permitted. An entity that elects early adoption must adopt all of the amendments in the same period and the new guidance must be applied on a retrospective basis. The Company has evaluated the effect of adopting this new accounting guidance and determined that adoption will not have a material impact on the Company’s Statement of Cash Flows. The Company will adopt this new accounting guidance as of September 1, 2018 (fiscal 2019).

Leases

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which supersedes Topic 840, Leases. Subsequently, the FASB has 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. The new guidance is effective for fiscal years beginning after December 15, 2018 (fiscal 2020), and interim periods within those fiscal years. In transition, lessees are required to recognize and measure leases at the beginning of the earliest period presented (fiscal 2018) using a modified retrospective approach which includes a number of optional practical expedients that entities may elect to apply. In July 2018, a new ASU was issued to provide relief to the companies from restating the comparative period. Pursuant to this ASU, WBA will not restate comparative periods presented in the Company’s financial statements in the period of adoption.

The Company will adopt this ASU on September 1, 2019 (fiscal 2020). The Company has begun evaluating and planning for adoption and implementation of this ASU, including implementing a new global lease accounting system, evaluating practical expedient and accounting policy elections and assessing the overall financial statement impact. This ASU will have a material impact on the Company’s financial position. The impact on the Company’s results of operations is being evaluated. The impact of this ASU is non-cash in nature and will not affect the Company’s cash flows.

Classification and measurement of financial instruments

In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. Subsequently, the FASB has issued additional ASUs which further clarify this guidance. This ASU requires equity investments (except those under the equity method of accounting or those that result in the consolidation of an investee) to be measured at fair value with changes in fair value recognized in net income. However, an entity may choose to measure equity investments that do not have readily determinable fair values at cost less impairment, if any, and changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. This simplifies the impairment assessment of equity investments previous held at cost. Separate presentation of financial assets and liabilities by measurement category is required. This ASU is effective prospectively for fiscal years beginning after December 15, 2017 (fiscal 2019), and interim periods within those fiscal years. Early application is permitted, for fiscal years or interim periods that have not yet been issued as of the beginning of the fiscal year of adoption. The new guidance must be applied on a modified retrospective basis, with the exception of the amendments related to the measurement alternative for equity investments without readily determinable fair values, which must be applied on a prospective basis. The Company has evaluated the effect of adopting this new accounting guidance and determined that adoption will not have a material impact on the Company’s results of operations. The Company will adopt this new accounting guidance as of September 1, 2018 (fiscal 2019).

Revenue recognition on contracts with customers

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). This ASU provides a single principles-based revenue recognition model with a five-step analysis of transactions to determine when and how revenue is recognized. The core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Subsequently, the FASB has issued additional ASUs which further clarify this guidance and also defer the effective date by one year to fiscal years beginning after December 15, 2017 (fiscal 2019), and interim periods within those fiscal years. The Company will use the modified retrospective method as the transition approach when adopting this new accounting guidance on September 1, 2018 (fiscal 2019). The Company has evaluated the effect of adopting this new accounting guidance, the related amendments and the interpretive guidance on the Company's Consolidated Financial Statements and determined that adoption will not have a material impact on the Company’s results of operations and will be limited to immaterial changes to recognition of revenues related to loyalty programs and gift cards, in addition to disaggregated revenue disclosures. Specifically, the Company currently uses the cost approach to account for loyalty programs. Upon adoption, the Company will use the deferred revenue approach. Additionally, gift card breakage currently is recognized at point of sale by the Retail Pharmacy USA segment and upon expiration primarily within the Retail Pharmacy International segment. Upon adoption of the new revenue recognition guidance, all breakage will be recognized based on the pattern in which the customer redeems the gift cards.
