NOTES TO FINANCIAL STATEMENTS

(UNAUDITED)

Note 1. Accounting policies

Basis of presentation

The Consolidated Condensed Financial Statements of Walgreens Boots Alliance, Inc. (“Walgreens Boots Alliance” or the “Company”) included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission regarding interim financial reporting. The Consolidated Condensed Financial Statements include all subsidiaries in which the Company holds a controlling interest. Investments in less than majority-owned subsidiaries in which the Company does not have a controlling interest, but does have significant influence, are accounted for as equity method investments. All intercompany transactions have been eliminated.

The Consolidated Condensed Financial Statements included herein are unaudited. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) have been condensed or omitted pursuant to such rules and regulations, although the Company believes that the disclosures are adequate to make the information presented not misleading. These unaudited Consolidated Condensed Financial Statements should be read in conjunction with the audited financial statements and the notes thereto included in the Walgreens Boots Alliance Annual Report on Form 10-K for the fiscal year ended August 31, 2017.

In the opinion of management, the unaudited Consolidated Condensed Financial Statements for the interim periods presented include all adjustments (consisting only of normal recurring adjustments) necessary to present a fair statement of the results for such interim periods. 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. With respect to the Company’s Retail Pharmacy USA segment, the positive impact on gross profit margins and gross profit dollars typically has been significant in the first several months after a generic version of a drug is first allowed to compete with the branded version, which is generally referred to as a “generic conversion”. In any given year, the number of major brand name drugs that undergo a conversion from branded to generic status can increase or decrease, which can have a significant impact on the Company’s Retail Pharmacy USA segment’s sales, gross profit margins and gross profit dollars making the Company’s operations or net earnings for any period incomparable.

Note 2. Acquisitions

Acquisition of certain Rite Aid Corporation (“Rite Aid”) assets

On September 19, 2017, the Company announced that it had secured regulatory clearance for an amended and restated asset purchase agreement to purchase 1,932 stores, three distribution centers and related inventory from Rite Aid for $4.375 billion in cash and other consideration. The purchases of these stores have been accounted for as business combinations and occurred in waves during fiscal 2018. The Company purchased 390 stores for total cash consideration of $820 million for the three months ended May 31, 2018 and 1,932 stores for total cash consideration of $4.2 billion for the nine months ended May 31, 2018. The transition of the three distribution centers and related inventory is expected to begin during fiscal 2019 and remains subject to closing conditions set forth in the amended and restated asset purchase agreement.

As of May 31, 2018, the Company had not completed the analysis to assign fair values to all tangible and intangible assets acquired and therefore the purchase price allocation has not been finalized. The preliminary purchase price allocation will be subject to further refinement and may result in material changes. These changes will primarily relate to the allocation of consideration and the fair value assigned to all tangible and intangible assets acquired and identified. During the three months ended May 31, 2018, the Company recorded certain measurement period adjustments to identified assets acquired and liabilities assumed based on additional information regarding such assets and liabilities, which did not have a material impact on the purchase price allocation. The following table summarizes the consideration for the purchases and the preliminary amounts of identified assets acquired and liabilities assumed as of the nine months ended May 31, 2018.

- 9 -

Consideration	$	4,330
Identifiable assets acquired and liabilities assumed
Inventories	$	1,291
Property, plant and equipment	494
Intangible assets	2,028
Accrued expenses and other liabilities	(54		)
Deferred income taxes	5
Other non-current liabilities	(795		)
Total identifiable net assets	2,969
Goodwill	$	1,361

The preliminary identified definite-lived intangible assets were as follows:

Definite-lived intangible assets	Weighted-average useful life (in years)	Amount (in millions)
Customer relationships	12	$	1,850
Favorable lease interests	6	158
Trade names and trademarks	2	20
Total		$	2,028

Consideration includes cash of $4,157 million and the fair value of the option granted to Rite Aid to become a member of the Company’s group purchasing organization, Walgreens Boots Alliance Development GmbH. The fair value for this option was determined using the income approach methodology.  The fair value estimates are based on the market compensation for such services and appropriate discount rate, as relevant, that market participants would consider when estimating fair values.

The goodwill of $1,361 million arising from the business combinations primarily reflects the expected operational synergies and cost savings generated from the Store Optimization Program as well as the expected growth from new customers. See note 3, exit and disposal activities, for additional information. The goodwill was allocated to the Retail Pharmacy USA segment. Substantially all of the goodwill recognized is expected to be deductible for income tax purposes.

The fair value for customer relationships was determined using the multi-period excess earnings method, a form of the income approach. Real property fair values were determined using primarily the income approach and sales comparison approach. The fair value measurements of the intangible assets are based on significant inputs not observable in the market, and thus represent Level 3 measurements. The fair value estimates for the intangible assets are based on projected discounted cash flows, historical and projected financial information, and attrition rates, as relevant, that market participants would consider when estimating fair values.

The following table presents supplemental unaudited condensed pro forma consolidated sales for the three and nine months ended May 31,2018 and 2017 as if all 1,932 stores acquired under the amended and restated asset purchase agreement had occurred on September 1, 2016. Pro forma net earnings of the Company, assuming these purchases had occurred at the beginning of each period presented, would not be materially different from the results reported. See note 3, exit and disposal activities, for additional information. The unaudited condensed pro forma information has been prepared for comparative purposes only and is not intended to be indicative of what the Company’s results would have been had the purchases occurred at the beginning of the periods presented or results which may occur in the future.

	Three months ended May 31,				Nine months ended May 31,
(in millions)	2018		2017		2018		2017
Sales	$	34,366	$	32,496	$	102,059	$	95,378

- 10 -

Actual sales from acquired Rite Aid stores for the three and nine months ended May 31,2018 included in the Consolidated Statement of Earnings are as follows:

(in millions)	Three months ended May 31, 2018		Nine months ended May 31, 2018
Sales	$	2,223	$	3,038

The 1,932 Rite Aid stores acquired did not have a material impact on net earnings of the Company for the three and nine months ended May 31, 2018.

AllianceRx Walgreens Prime

On March 31, 2017, Walgreens Boots Alliance and pharmacy benefit manager Prime Therapeutics LLC (“Prime”) closed a transaction to form a combined central specialty pharmacy and mail services company AllianceRx Walgreens Prime, as part of a strategic alliance. AllianceRx Walgreens Prime is consolidated by Walgreens Boots Alliance and reported within the Retail Pharmacy USA division in its financial statements. The Company accounted for this acquisition of Prime’s specialty pharmacy and mail services business as a business combination involving noncash purchase consideration of $720 million consisting of the issuance of an equity interest in AllianceRx Walgreens Prime.

The Company has completed the purchase accounting for the AllianceRx Walgreens Prime transaction. The following table summarizes the consideration for the acquisition and the amounts of identified assets acquired and liabilities assumed at the date of the transaction (in millions).

Consideration	$	720
Identifiable assets acquired and liabilities assumed
Accounts receivable	$	217
Inventories	149
Property, plant and equipment	11
Intangible assets	331
Trade accounts payable	(90		)
Accrued expenses and other liabilities	(1		)
Total identifiable net assets	617
Goodwill	$	103

The identified intangible assets primarily include purchasing and payer contracts. These contracts are estimated to have a weighted average useful life of 15 years. The goodwill of $103 million arising from the transaction consists of expected purchasing synergies, operating efficiencies by benchmarking performance and applying best practices across the combined company, consolidation of operations, reductions in selling, general and administrative expenses and combining workforces. Substantially all of the goodwill recognized is not expected to be deductible for income tax purposes.

In accordance with ASC Topic 810, Consolidation, the noncontrolling interest was recognized based on its proportionate interest in the identifiable net assets of AllianceRx Walgreens Prime. The difference between the carrying amount of the noncontrolling interest and the fair value recognized as consideration in the business combination is recognized as additional paid in capital.

Note 3. Exit and disposal activities

On October 24, 2017, the Company’s Board of Directors approved a plan to implement a program (the “Store Optimization Program”) as part of an initiative to optimize store locations within the Company’s Retail Pharmacy USA segment upon completion of the acquisition of certain stores and related assets from Rite Aid. The Store Optimization Program includes plans to close approximately 600 stores and related assets across the U.S. The actions under the Store Optimization Program commenced in March 2018 and are expected to take place over an 18 month period.

The Company currently estimates that it will recognize cumulative pre-tax charges to its GAAP financial results of approximately $450 million, including costs associated with lease obligations and other real estate costs, employee severance

- 11 -

and other exit costs. The Company expects to incur pre-tax charges of approximately $270 million for lease obligations and other real estate costs and approximately $180 million for employee severance and other exit costs. The Company estimates that substantially all of these cumulative pre-tax charges will result in cash expenditures.

Costs related to the Store Optimization Program, which were primarily recorded in selling, general and administrative expenses for the Company's Retail Pharmacy USA segment included in the three and nine months ended May 31, 2018, are as follows (in millions):

Three months ended May 31, 2018
Lease obligations and other real estate costs	2

Total costs	$	24

Nine months ended May 31, 2018
Lease obligations and other real estate costs	2
Employee severance and other exit costs	22

¹  Represents unfavorable lease liabilities from acquired Rite Aid stores.

On April 8, 2015, the Walgreens Boots Alliance Board of Directors approved a plan to implement a restructuring program (the “Cost Transformation Program”) as part of an initiative to reduce costs and increase operating efficiencies. The Cost Transformation Program implemented and built on the cost-reduction initiative previously announced by the Company on August 6, 2014 and included plans to close stores across the U.S.; reorganize corporate and field operations; drive operating efficiencies; and streamline information technology and other functions. The actions under the Cost Transformation Program focused primarily on the Retail Pharmacy USA segment, but included activities from all segments. The Company completed the Cost Transformation Program in the fourth quarter of fiscal 2017.

The changes in liabilities related to the Cost Transformation Program for the nine months ended May 31, 2018 include the following (in millions):

	Real estate costs			Severance and other business transition and exit costs			Total

Note 4. Operating 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. The Company recognizes rent expense on a straight-line basis over the term of the lease. In addition to minimum fixed rentals, some leases provide for contingent rentals based upon a portion of sales.

The Company continuously evaluates its real estate portfolio in conjunction with its capital needs. Historically, the Company has entered into several sale-leaseback transactions. For the nine months ended May 31, 2018, the Company did not record any proceeds from sale-leaseback transactions. For the nine months ended May 31, 2017, the Company recorded proceeds from sale-leaseback transactions of $436 million.

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. During the three and nine months ended May 31, 2018, the Company recorded charges of $21 million and $88 million for facilities that were closed. This compares to $25 million and $289 million for the three and nine months ended May 31, 2017. These charges are reported in selling, general and administrative expenses in the Consolidated Condensed Statements of Earnings.

The changes in reserve for facility closings and related lease termination charges primarily in other non-current liabilities, include the following (in millions):

As of May 31, 2018, the Company remains secondarily liable on 71 leases. The maximum potential undiscounted future payments are $311 million as of May 31, 2018.

Note 5. Equity method investments

Equity method investments as of May 31, 2018 and August 31, 2017, are as follows (in millions, except percentages):

	May 31, 2018			August 31, 2017
	Carrying value		Ownership percentage	Carrying value		Ownership percentage
AmerisourceBergen	$	5,120	26%	$	5,024	26%
Others	1,152		8% - 50%	1,296		8% - 50%
Total	$	6,272		$	6,320

AmerisourceBergen investment

As of May 31, 2018 and August 31, 2017, the Company owned 56,854,867 AmerisourceBergen Corporation (“AmerisourceBergen”) common shares, representing approximately 26% of the outstanding AmerisourceBergen common stock. The Company accounts for its equity investment in AmerisourceBergen using the equity method of accounting, with the net earnings attributable to the Company’s investment being classified within the operating income of its Pharmaceutical Wholesale segment. Due to the timing and availability of financial information of AmerisourceBergen, the Company accounts for this equity method investment on a financial reporting lag of two months. Equity earnings from AmerisourceBergen are reported as a separate line in the Consolidated Condensed Statements of Earnings. The level 1 fair market value of the Company’s equity investment in AmerisourceBergen common stock at May 31, 2018 is $4.7 billion.

As of May 31, 2018, the Company’s investment in AmerisourceBergen carrying value exceeded its proportionate share of the net assets of AmerisourceBergen by $4.2 billion. This premium of $4.2 billion was recognized as part of the carrying value in the Company’s equity investment in AmerisourceBergen. The difference was primarily related to goodwill and the fair value of AmerisourceBergen intangible assets.

Other investments

The Company’s other equity method investments include its investments in Guangzhou Pharmaceuticals Corporation (“Guangzhou Pharmaceuticals”) and Nanjing Pharmaceutical Corporation Limited, the Company’s pharmaceutical wholesale investments in China; and the equity method investment retained through the sale of a majority interest in Option Care Inc. in fiscal 2015.

The Company reported $15 million of post-tax equity earnings and $21 million of post-tax equity losses from other equity method investments for the three months ended May 31, 2018 and May 31, 2017, respectively. The Company reported $42 million and $7 million of post-tax equity earnings from other equity method investments for the nine months ended May 31, 2018 and May 31, 2017, respectively. During the nine month period ended May 31, 2018, the Company recorded an impairment of $170 million in its equity interest in Guangzhou Pharmaceuticals, which was included in other income (expense) in the Consolidated Condensed Statements of Earnings. The fair value of the Company’s equity interest in Guangzhou Pharmaceuticals was determined using the proposed sale price and thus represents Level 3 measurement. During the three months ended May 31, 2018, the Company completed the sale of a 30 percent interest in Guangzhou Pharmaceuticals to its joint venture partner Guangzhou Baiyunshan Pharmaceutical Holdings resulting in a $172 million reduction in carrying value and a $8 million cumulative translation adjustment loss.

²  Credit facilities includes borrowings outstanding under the February 2017 Revolving Credit Agreement, the August 2017 Revolving Credit Agreement and the 2017 Term Loan Credit Agreement, which are described in more detail below. From time to time, the Company may also enter into other credit facilities, including in March 2018, a $350 million short-term unsecured revolving credit facility which was undrawn as of May 31, 2018.

³  The $6 billion, $8 billion, £0.7 billion, €0.75 billion, $4 billion and $1 billion note issuances as of May 31, 2018 had fair values and carrying values of $2.4 billion and $2.5 billion, $6.4 billion and $6.5 billion, $1.0 billion and $0.9 billion, $0.9 billion and $0.9 billion, $1.7 billion and $1.7 billion, and $0.3 billion and $0.2 billion, respectively. The fair values of the notes outstanding are level 1 fair value measures and determined based on quoted market price and translated at the May 31, 2018 spot rate, as applicable. The fair values and carrying values of these issuances do not include notes that have been redeemed or repaid as of May 31, 2018.

⁶  Other short-term debt represents a mix of fixed and variable rate borrowings with various maturities and working capital facilities denominated in various currencies.

⁷  Notes are unsubordinated debt obligations of Walgreens Boots Alliance and rank equally in right of payment with all other unsecured and unsubordinated indebtedness of Walgreens Boots Alliance from time to time outstanding.

⁸  Other long-term debt represents a mix of fixed and variable rate borrowings in various currencies with various maturities.

August 2017 Credit Agreements

On August 24, 2017, the Company entered into a $1.0 billion revolving credit agreement with the lenders from time to time party thereto (the “August 2017 Revolving Credit Agreement”) and a $1.0 billion term loan credit agreement with Sumitomo Mitsui Banking Corporation (the “2017 Term Loan Credit Agreement”).

The August 2017 Revolving Credit Agreement is an unsecured revolving credit facility with a facility termination date of the earlier of (a) January 31, 2019, subject to any extension thereof pursuant to the terms of the August 2017 Revolving Credit Agreement and (b) the date of termination in whole of the aggregate commitments provided by the lenders thereunder. As of May 31, 2018, there were no borrowings outstanding under the August 2017 Revolving Credit Agreement. The 2017 Term Loan Credit Agreement is an unsecured “multi-draw” term loan facility which matures on March 30, 2019.  As of May 31, 2018, Walgreens Boots Alliance had $1.0 billion of borrowings outstanding under the 2017 Term Loan Credit Agreement, and no additional commitments were available.

February 2017 Revolving Credit Agreement

On February 1, 2017, the Company entered into a $1.0 billion revolving credit facility (as amended, the “February 2017 Revolving Credit Agreement”) with the lenders from time to time party thereto and, on August 1, 2017, the Company entered into an amendment agreement thereto. The terms and conditions of the February 2017 Revolving Credit Agreement were unchanged by the amendment other than the extension of the facility termination date to the earlier of (a) January 31, 2019 and (b) the date of termination in whole of the aggregate commitments provided by the lenders thereunder. As of May 31, 2018, there were no borrowings outstanding under the February 2017 Revolving Credit Agreement.

$6.0 billion note issuance

On June 1, 2016, Walgreens Boots Alliance received net proceeds of $6.0 billion from a public offering of five series of U.S. dollar notes with varying maturities and interest rates. Because the merger with Rite Aid was not consummated on or prior to June 1, 2017, the 2018 notes, the 2021 notes and the 2023 notes were redeemed on June 5, 2017 under the special mandatory redemption terms of the indenture governing such notes. Walgreens Boots Alliance was required to redeem all of the 2018 notes, the 2021 notes and the 2023 notes then outstanding, at a special mandatory redemption price equal to 101% of the aggregate principal amount of such notes, plus accrued and unpaid interest of approximately $1 million to, but excluding, the date of redemption. The 2026 notes and 2046 notes remain outstanding in accordance with their respective terms.

Debt covenants

Each of the Company’s credit facilities contain a covenant to maintain, as of the last day of each fiscal quarter, a ratio of consolidated debt to total capitalization not to exceed 0.60:1.00. The credit facilities contain various other customary covenants.

Commercial paper

The Company periodically borrows under its commercial paper program and may borrow under it in future periods. The Company had average daily short-term borrowings of $1.4 billion of commercial paper outstanding at a weighted average interest rate of 2.00% for the nine months ended May 31, 2018. The Company had no activity under its commercial paper program for the nine months ended May 31, 2017.

Interest

Interest paid was $450 million and $573 million for the nine months ended May 31, 2018 and May 31, 2017, respectively.

Note 8. Financial instruments

The Company uses derivative instruments to manage its exposure to interest rate and foreign currency exchange risks.

The notional amounts, fair value and balance sheet presentation of derivative instruments outstanding as of May 31, 2018 and August 31, 2017 are as follows (in millions):

- 17 -

	May 31, 2018				August 31, 2017
	Notional 1		Fair value		Notional 1		Fair value		Location in Consolidated Condensed Balance Sheets

Derivatives not designated as hedges:

Foreign currency forwards	—		—		2,816		19		Other current liabilities

¹  Amounts are presented in U.S. dollar equivalents, as applicable.

The Company uses interest rate swaps to manage the interest rate exposure associated with some of its fixed-rate borrowings and designates them as fair value hedges. From time to time, the Company may use forward starting interest rate swaps to hedge interest rate exposure of some or all of its anticipated debt issuances.

The Company utilizes foreign currency forward contracts and other foreign currency derivatives to hedge significant committed and highly probable future transactions and cash flows denominated in currencies other than the functional currency of the Company or its subsidiaries. The Company has significant non-U.S. dollar denominated net investments and uses foreign currency denominated financial instruments, specifically foreign currency derivatives and foreign currency denominated debt, to hedge its foreign currency risk.

Fair value hedges

The Company holds an interest rate swap converting $250 million of its 5.250% fixed rate notes to a floating interest rate based on the six-month LIBOR in arrears plus a constant spread. The swap termination date coincides with the January 15, 2019 maturity date of the notes. This swap was designated as a fair value hedge.

The gains and losses due to changes in fair value on the swaps and on the hedged notes attributable to interest rate risk did not have a material impact on the Company’s Financial Statements. The changes in fair value of the Company’s debt that was swapped from fixed to variable rate and designated as fair value hedges are included in long-term debt on the Consolidated Condensed Balance Sheets (see note 7, debt).

Derivatives not designated as hedges

The Company enters into derivative transactions that are not designated as accounting hedges. These derivative instruments are economic hedges of foreign currency risks. The income and (expense) due to changes in fair value of these derivative instruments were recognized in earnings as follows (in millions):

		Three months ended May 31,					Nine months ended May 31,
	Location in Consolidated Condensed Statements of Earnings	2018		2017			2018			2017
Foreign currency forwards	Selling, general and administrative expenses	$	108	$	(19	)	$	(75	)	$	28
Foreign currency forwards	Other income (expense)	3		(1		)	36			(15		)

Derivatives credit risk

Counterparties to derivative financial instruments expose the Company to credit-related losses in the event of counterparty nonperformance, and the Company regularly monitors the credit worthiness of each counterparty.

Derivatives offsetting

The Company does not offset the fair value amounts of derivative instruments subject to master netting agreements in the Consolidated Condensed Balance Sheets.

Note 9. Fair value measurements

The Company measures certain assets and liabilities in accordance with ASC Topic 820, Fair Value Measurements and Disclosures, which defines fair value as the price that would be received for an asset or paid to transfer a liability in an orderly

- 18 -

transaction between market participants on the measurement date. In addition, it establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three broad levels:

Level 1 - Quoted prices in active markets that are accessible at the measurement date for identical assets and liabilities. The fair value hierarchy gives the highest priority to level 1 inputs.

Level 2 - Observable inputs other than quoted prices in active markets.

Level 3 - Unobservable inputs for which there is little or no market data available. The fair value hierarchy gives the lowest priority to level 3 inputs.

Assets and liabilities measured at fair value on a recurring basis are as follows (in millions):

	May 31, 2018		Level 1		Level 2		Level 3
Assets:
Money market funds1	$	1,104	$	1,104	$	—	$	—
Available-for-sale investments2	1		1		—		—

¹  Money market funds are valued at the closing price reported by the fund sponsor.

²  The fair value of quoted investments are based on current bid prices as of the balance sheet dates.

³  The fair value of forward currency contracts are estimated by discounting the difference between the contractual forward price and the current available forward price for the residual maturity of the contract using observable market rates.

⁴  The fair value of interest rate swaps is calculated by discounting the estimated future cash flows based on the applicable observable yield curves. See note 8, financial instruments for additional information.

There were no transfers between levels for the three and nine months ended May 31, 2018.

The Company reports its debt instruments under the guidance of ASC Topic 825, Financial Instruments, which requires disclosure of the fair value of the Company’s debt in the footnotes to the Consolidated Financial Statements. Unless otherwise noted, the fair value for all notes was determined based upon quoted market prices and therefore categorized as level 1. See note 7, debt for further information. The carrying values of accounts receivable, net and trade accounts payable approximated their respective fair values due to their short-term nature.

Note 10. Commitments and contingencies

The Company is involved in legal proceedings and is subject to investigations, inspections, audits, inquiries and similar actions by governmental authorities, arising in the normal course of the Company’s business, including the matters described below. Legal proceedings, in general, and securities and class action litigation, in particular, can be expensive and disruptive. Some of these suits may purport or may be determined to be class actions and/or involve parties seeking large and/or indeterminate amounts, including punitive or exemplary damages, and may remain unresolved for several years. From time to time, the Company is also involved in legal proceedings as a plaintiff involving antitrust, tax, contract, intellectual property and other matters. Gain contingencies, if any, are recognized when they are realized. The results of legal proceedings are often uncertain and difficult to predict, and the costs incurred in litigation can be substantial, regardless of the outcome. The Company believes that its defenses and assertions in pending legal proceedings have merit, and does not believe that any of these pending matters, after consideration of applicable reserves and rights to indemnification, will have a material adverse effect on the Company’s consolidated financial position. However, substantial unanticipated verdicts, fines and rulings do sometimes occur. As a result, the Company could from time to time incur judgments, enter into settlements or revise its expectations regarding the outcome

- 19 -

of certain matters, and such developments could have a material adverse effect on its results of operations in the period in which the amounts are accrued and/or its cash flows in the period in which the amounts are paid.

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 is 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.

On December 29, 2014, a putative shareholder filed a derivative action in federal court in the Northern District of Illinois against certain current and former directors and officers of Walgreen Co., and Walgreen Co. as a nominal defendant, arising out of certain public statements the Company made regarding its former fiscal 2016 goals. The action asserts claims for breach of fiduciary duty, waste and unjust enrichment. On April 10, 2015, the defendants filed a motion to dismiss. On May 18, 2015, the case was stayed in light of a securities class action that was filed on April 10, 2015. After a ruling issued on September 30, 2016 in the securities class action, which is described below, on November 3, 2016, the Court entered a stipulation and order extending the stay until the securities case is fully resolved.

On April 10, 2015, a putative shareholder filed a securities class action in federal court in the Northern District of Illinois against Walgreen Co. and certain former officers of Walgreen Co. The action asserts claims for violation of the federal securities laws arising out of certain public statements the Company made regarding its former fiscal 2016 goals. On June 16, 2015, the Court entered an order appointing a lead plaintiff. Pursuant to the Court’s order, lead plaintiff filed an amended complaint on August 17, 2015, and defendants moved to dismiss the amended complaint on October 16, 2015. Lead plaintiff filed a response to the motion to dismiss on December 22, 2015, and defendants filed a reply in support of the motion on February 5, 2016. On September 30, 2016, the Court issued an order granting in part and denying in part defendants’ motion to dismiss. Defendants filed their answer to the amended complaint on November 4, 2016 and filed an amended answer on January 16, 2017. Plaintiffs filed their motion for class certification on April 21, 2017. Plaintiffs’ motion was granted on March 29, 2018 and merits discovery is proceeding.

As of August 31, 2017, the Company was aware of two putative class action lawsuits filed by purported Rite Aid stockholders against Rite Aid and its board of directors, Walgreens Boots Alliance and Victoria Merger Sub, Inc. for claims arising out of the transactions contemplated by the original Merger Agreement (prior to its amendment on January 29, 2017) (such transactions, the “Rite Aid Transactions”). One Rite Aid action was filed in the State of Pennsylvania in the Court of Common Pleas of Cumberland County (the “Pennsylvania action”), and one action was filed in the United States District Court for the Middle District of Pennsylvania (the “federal action”). The Pennsylvania action primarily alleged that the Rite Aid board of directors breached its fiduciary duties in connection with the Rite Aid Transactions by, among other things, agreeing to an unfair and inadequate price, agreeing to deal protection devices that preclude other bidders from making successful competing offers for Rite Aid, and failing to disclose all allegedly material information concerning the proposed merger, and also alleged that Walgreens Boots Alliance and Victoria Merger Sub, Inc. aided and abetted these alleged breaches of fiduciary duty. The federal action alleged, among other things, that Rite Aid and its board of directors disseminated an allegedly false and misleading proxy statement in connection with the Rite Aid Transactions. The plaintiffs in the federal action also filed a motion for preliminary injunction seeking to enjoin the Rite Aid shareholder vote relating to the Rite Aid Transactions. That motion was denied and plaintiffs agreed to stay the litigation until after the Rite Aid Transactions closed. On March 17, 2017, plaintiffs moved to lift the stay to allow plaintiffs to file an amended complaint. On August 4, 2017, that motion was granted for the limited purpose of allowing plaintiffs to file a motion seeking leave to amend their complaint in light of the termination of the Merger Agreement. Plaintiffs filed such a motion on September 22, 2017. The Company filed its response on October 6, 2017. The Court granted the motion on November 27, 2017, ordering the plaintiffs to file their amended complaint within 10 business days. Plaintiffs filed their amended complaint on December 11, 2017. Pursuant to a briefing schedule set by the Court, the

- 20 -

Company filed a motion to dismiss on February 16, 2018. Plaintiffs filed their response brief on May 1, 2018 and reply briefs were filed on June 7, 2018.

The Company was also named as a defendant in eight putative class action lawsuits filed in the Court of Chancery of the State of Delaware (the “Delaware actions”). Those actions were consolidated, and plaintiffs filed a motion for preliminary injunction seeking to enjoin the Rite Aid shareholder vote relating to the Rite Aid Transactions. That motion was denied and the plaintiffs in the Delaware actions agreed to settle this matter for an immaterial amount. The Delaware actions all have been dismissed.

In December 2017, the United States Judicial Panel on Multidistrict Litigation consolidated numerous cases filed against an array of defendants by various plaintiffs such as counties, cities, hospitals, Indian tribes and others, alleging claims generally concerning the impacts of widespread opioid abuse. The consolidated multidistrict litigation, captioned In re National Prescription Opiate Litigation (MDL No. 2804), is pending in the U.S. District Court for the Northern District of Ohio. The Company is named as a defendant in a subset of the cases included in this multidistrict litigation. The Company also has been named as a defendant in several lawsuits brought in state courts relating to opioid matters. The relief sought by various plaintiffs is compensatory and punitive damages, as well as injunctive relief. Additionally, the Company has received from the Attorney Generals of several states subpoenas, civil investigative demands, and/or other requests concerning opioid matters.

Note 11. Income taxes

The effective tax rate for the three and nine months ended May 31, 2018 was 7.6% and 19.4% respectively, compared to 12.4% and 16.2% for the three and nine months ended May 31, 2017. As further described below, the decrease in the effective tax rate for the three months ended and the increase in the effective tax rate for the nine months endedMay 31, 2018 were significantly impacted by an additional provisional net tax benefit of $140 million and a provisional net tax expense of $44 million respectively, as a result of the U.S. tax law changes, which were enacted on December 22, 2017. The decrease in the prior year comparable periods are due to higher net discrete tax benefits. In addition, the Company's results for the three and nine months ended May 31, 2018 also include a net reduction to the Company’s estimated annual tax rate for the current year as a result of the U.S. tax law changes.

Income taxes paid for the nine months endedMay 31, 2018 were $428 million, compared to $839 million for the nine months endedMay 31, 2017.

U.S. tax law changes

The United States government enacted comprehensive tax legislation in December 2017. The accounting guidance on income taxes generally requires the effects of new tax legislation to be recognized in the period of enactment. The SEC issued Staff Accounting Bulletin 118 (“SAB 118”), which provides for a measurement period of up to one year from the enactment date for companies to complete their accounting for the U.S. tax law changes. In accordance with the SEC staff guidance, companies must reflect the income tax effects of those aspects of the U.S. tax law changes for which the accounting is complete. To the extent a company’s accounting for the income tax effect of certain provisions of the U.S. tax law changes is incomplete but the Company is able to determine a reasonable estimate, a provisional estimate must be recorded in the Company’s financial statements. If companies cannot determine a provisional estimate for the effects of an aspect of the U.S. tax law changes, they should continue applying the accounting guidance on income taxes on the basis of the provisions of the tax laws in effect immediately before the U.S. tax law changes were enacted.

The U.S. tax law changes include broad and complex changes affecting the Company’s fiscal 2018 results. Among other things, the U.S. tax law changes reduce the federal corporate tax rate from 35% to 21% effective January 1, 2018 and require companies to immediately accrue for and pay over an eight year period a one-time transition tax on certain un-repatriated earnings of foreign subsidiaries. The U.S. tax law changes also alter the taxation of foreign earnings, repeal of the deduction for domestic production activities and establish a global intangible low tax income (GILTI) regime, as well as base erosion anti-avoidance tax (BEAT).

In connection with the Company’s ongoing analysis of the impact of the U.S. tax law changes, which is provisional and subject to change, the Company recorded a net tax expense of $44 million during the nine months ended May 31, 2018. This provisional net tax expense arises from the Company’s accrual for the transition tax and other U.S. tax law changes of $679 million, partly offset by a benefit of $635 million from re-measuring the Company’s net U.S. deferred tax liabilities.

Based on the effective dates of certain aspects of the U.S. tax law changes as well as estimated data required to be used in the corresponding measurement calculations, the Company’s analysis of the income tax effects of the U.S. tax law changes could not be finalized as of May 31, 2018. While the Company made reasonable estimates of the impact of the transition tax and the remeasurement of its deferred tax assets and liabilities, the final impact of the U.S. tax law changes may differ from these estimates, due to, among other things, changes in its interpretations and assumptions, additional guidance and actions the

- 21 -

Company may take. The Company expects to finalize such provisional amounts within the time period prescribed by SAB 118. The U.S. tax law changes created new rules that allow the Company to make an accounting policy election to either treat taxes due on future GILTI inclusions in taxable income as either a current period expense or reflect such inclusions related to temporary basis differences in the Company’s measurement of deferred taxes. The Company’s analysis of the new GILTI rules is not complete; therefore, the Company has not made a policy election regarding the tax accounting treatment of the GILTI tax.

The U.S. tax law changes have the potential to change the Company’s assertions with respect to whether earnings of the Company’s foreign subsidiaries should remain indefinitely reinvested. The Company continues to evaluate these changes, therefore, the Company has not made any changes to its indefinite reinvestment assertions.

Note 12. Retirement benefits

The Company sponsors several retirement plans, including defined benefit plans, defined contribution plans and a postretirement health plan.

Defined benefit pension plans (non-U.S. plans)

The Company has various defined benefit pension plans outside the United States. The principal defined benefit pension plan is the Boots Pension Plan, which covers certain employees in the United Kingdom (the “Boots Plan”). The Boots Plan is a funded final salary defined benefit plan providing pensions and death benefits to members. The Boots Plan was closed to future accrual effective July 1, 2010, with pensions calculated based on salaries up until that date. The Boots Plan is governed by a trustee board, which is independent of the Company. The plan is subject to a full funding actuarial valuation on a triennial basis.

Components of net periodic pension costs for the defined benefit pension plans (in millions):

	Three months ended May 31,						Nine months ended May 31,
	2018			2017			2018			2017

Expected returns on plan assets/other	(54		)	(41		)	(158		)	(112		)
Total net periodic pension costs	$	(2	)	$	3		$	(7	)	$	20

The Company made cash contributions to its defined benefit pension plans of $57 million for the nine months ended May 31, 2018, which primarily related to committed funded payments. The Company plans to contribute an additional $7 million to its defined benefit pension plans in fiscal 2018.

Defined contribution plans

The principal retirement plan for U.S. employees is the Walgreen Profit-Sharing Retirement Trust, to which both the Company and participating employees contribute. The Company’s contribution is in the form of a guaranteed match which is approved annually by the Walgreen Co. Board of Directors and reviewed by the Compensation Committee and Finance Committee of the Walgreens Boots Alliance Board of Directors. The profit-sharing provision was an expense of $53 million and $164 million for the three and nine months ended May 31, 2018 compared to an expense of $58 million and $164 million in the three and nine months ended May 31, 2017.

The Company also has certain contract based defined contribution arrangements. The principal one is the Alliance Healthcare & Boots Retirement Savings Plan, which is United Kingdom based and to which both the Company and participating employees contribute. The cost recognized in the Consolidated Condensed Statements of Earnings for the three and nine months ended May 31, 2018 was $33 million and $94 million compared to a cost of $26 million and $82 million in the three and nine months ended May 31, 2017.

Postretirement healthcare plan

The Company provides certain health insurance benefits to retired U.S. employees who meet eligibility requirements, including age, years of service and date of hire. The costs of these benefits are accrued over the service life of the employee. An amendment to this plan in the third quarter of fiscal 2017 resulted in a $109 million curtailment gain.

Note 13. 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. There were 12.1 million outstanding options to purchase common shares that were anti-dilutive and excluded from the third quarter earnings per share calculation as of May 31, 2018 compared to 6.4 million as of May 31, 2017. Anti-dilutive shares excluded from the year to date earnings per share calculation were 10.1 million for the period ended May 31, 2018 compared to 5.7 million for the period ended May 31, 2017.

Note 14. Accumulated other comprehensive income (loss)

The following is a summary of net changes in accumulated other comprehensive income by component and net of tax for the three and nine months ended May 31, 2018 and May 31, 2017 (in millions):

Note 15. Segment reporting

The Company has aligned its operations into three reportable segments: Retail Pharmacy USA, Retail Pharmacy International, and Pharmaceutical Wholesale. The operating segments have been identified based on the financial data utilized by the Company’s Chief Executive Officer (the chief operating decision maker) to assess segment performance and allocate resources among the Company’s operating segments, which have been aggregated as described below. The chief operating decision maker uses adjusted operating income to assess segment profitability. The chief operating decision maker does not use total assets by segment to make decisions regarding resources, therefore the total asset disclosure by segment has not been included.

• The Retail Pharmacy USA segment consists of the Walgreens business, which includes the operation of retail drugstores and convenient care clinics; and operation of mail and central specialty pharmacy services. Sales for the segment are principally derived from the sale of prescription drugs and a wide assortment of retail products, including health and wellness, beauty, personal care and consumables and general merchandise.

• The Retail Pharmacy International segment consists of pharmacy-led health and beauty retail businesses and optical practices. These businesses include Boots branded stores in the United Kingdom, Thailand, Norway, the Republic of Ireland and the Netherlands; Benavides in Mexico and Ahumada in Chile. Sales for the segment are principally derived from the sale of prescription drugs and health and wellness, beauty, personal care and other consumer products.

• The Pharmaceutical Wholesale segment consists of the Alliance Healthcare pharmaceutical wholesaling and distribution businesses and an equity method investment in AmerisourceBergen. Wholesale operations are located in the United Kingdom, Germany, France, Turkey, Spain, the Netherlands, Egypt, Norway, Romania, Czech Republic and Lithuania. Sales for the segment are principally derived from wholesaling and distribution of a comprehensive offering of brand-name pharmaceuticals (including specialty pharmaceutical products) and generic pharmaceuticals, health and beauty products, home healthcare supplies and equipment, and related services to pharmacies and other healthcare providers.

The results of operations for each reportable segment include procurement benefits and an allocation of corporate-related overhead costs. The “Eliminations” column contains items not allocable to the reportable segments, as the information is not utilized by the chief operating decision maker to assess segment performance and allocate resources.

Note 17. New accounting pronouncements

Adoption of new accounting pronouncements

Accounting for hedging activities

In August 2017, the FASB issued 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

- 27 -

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. The updated accounting policy for financial instruments is as follows:

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 - 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 Statements of Earnings when the hedged item affects earnings. When a derivative in a hedge relationship is terminated or the hedged item is sold, extinguished or terminated, hedge accounting is discontinued prospectively.

New accounting pronouncements not yet adopted

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

- 28 -

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 is evaluating the effect of adopting this new accounting guidance. 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).

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-

- 29 -

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.

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 minus impairment, if any, plus or minus 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 continues to evaluate the impact of this ASU, the related amendments and the interpretive guidance on the Company's consolidated financial statements, and will use the modified retrospective method as the transition approach when adopting this new accounting guidance on September 1, 2018 (fiscal 2019). Based on the preliminary assessment, the impact of adopting the new guidance will not be material to the consolidated financial statements and will be limited to immaterial changes to the timing of 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.

Note 19. Subsequent event

On June 28, 2018, Premise Health Holding Corp. and OMERS, a Canadian pension fund, announced that an affiliate of OMERS will acquire control of Premise Health, which is currently owned by an entity in which the Company indirectly holds a minority equity interest. The transaction, which is subject to customary closing conditions, is expected to be completed in July 2018. Upon closing, the Company estimates that it would recognize an after-tax gain on disposition of approximately $272 million, which the Company intends to treat as a special item impacting the comparability of results.

Item 2. Management’s discussion and analysis of financial condition and results of operations

The following discussion and analysis of our financial condition and results of operations should be read together with the financial statements and the related notes included elsewhere herein and the Consolidated Financial Statements, accompanying notes and Management’s discussion and analysis of financial condition and results of operations and other disclosures contained in the Walgreens Boots Alliance, Inc. Annual Report on Form 10-K for the fiscal year ended August 31, 2017. This discussion contains forward-looking statements that involve risks and uncertainties. Our actual results may differ materially from those discussed in forward-looking statements. Factors that might cause a difference include, but are not limited to, those discussed under “Cautionary note regarding forward-looking statements” below and in Item 1A “Risk factors” in our Form 10-K for the fiscal year ended August 31, 2017 and in our Form 10-Q for the fiscal quarter ended November 30, 2017. References herein to the “Company”, “we”, “us”, or “our” refer to Walgreens Boots Alliance, Inc. and its subsidiaries, except as otherwise indicated or the context otherwise requires.

INTRODUCTION AND SEGMENTS

Walgreens Boots Alliance, Inc. (“Walgreens Boots Alliance”) and its subsidiaries are a global pharmacy-led health and wellbeing enterprise. Its operations are conducted through three reportable segments:

• Retail Pharmacy USA;

• Retail Pharmacy International; and

• Pharmaceutical Wholesale

See note 15, segment reporting for further information.

Acquisition of certain Rite Aid Corporation (“Rite Aid”) assets

On September 19, 2017, the Company announced it had secured regulatory clearance for an amended and restated asset purchase agreement to purchase 1,932 stores, three distribution centers and related inventory from Rite Aid for $4.375 billion in cash and other consideration. The Company has completed the acquisition of all 1,932 Rite Aid stores. The transition of the three distribution centers and related inventory is expected to begin during fiscal 2019 and remains subject to closing conditions set forth in the amended and restated asset purchase agreement.

The Company continues to expect to complete integration of the acquired stores and related assets by the end of fiscal 2020, at an estimated total cost of approximately $750 million, which is reported as acquisition-related costs. In addition, the Company continues to expect to spend approximately $500 million of capital on store conversions and related activities. The Company continues to expect annual synergies from the transaction of more than $300 million, which are expected to be fully realized within four years of the initial closing of this transaction and derived primarily from procurement, cost savings and other operational matters.

The amounts and timing of all estimates are subject to change until finalized. The actual amounts and timing may vary materially based on various factors. See “cautionary note regarding forward-looking statements” below.

Comparability

The influence of certain holidays, seasonality, foreign currency rates, changes in vendor, payer and customer relationships and terms, strategic transactions including acquisitions, for example the acquisition of stores and other assets from Rite Aid, joint ventures and other strategic collaborations, changes in laws, for example the U.S. tax law changes, 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 and are not necessarily indicative of future operating results.

RECENT DEVELOPMENTS

Premise Health

On June 28, 2018, Premise Health Holding Corp. and OMERS, a Canadian pension fund, announced that an affiliate of OMERS will acquire control of Premise Health, which is currently owned by an entity in which the Company indirectly holds a minority equity interest. The transaction, which is subject to customary closing conditions, is expected to be completed in July 2018. Upon closing, the Company estimates that it would recognize an after-tax gain on disposition of approximately $272 million, which the Company intends to treat as a special item impacting the comparability of results. See “cautionary note regarding forward-looking statements” below.

U.S. tax law changes

The United States government enacted comprehensive tax legislation in December 2017. The U.S. tax law changes include broad and complex changes affecting the Company's fiscal 2018 results. Among other things, the U.S. tax law changes reduce the federal corporate tax rate from 35% to 21% effective January 1, 2018 and require companies to immediately accrue for and pay over an eight year period a one-time transition tax on certain un-repatriated earnings of foreign subsidiaries. The U.S. tax law changes also alter the taxation of foreign earnings, repeal the deduction for domestic production activities and establish a global intangible low tax income (GILTI) regime as well as a base erosion anti-avoidance tax (BEAT).

In connection with the Company’s ongoing analysis of the impact of the U.S. tax law changes, which is provisional and subject to change, the Company recorded a net tax expense of $44 million during the nine months ended May 31, 2018. This provisional net tax expense arises from the Company’s accrual for the transition tax and other U.S. tax law changes of $679 million, partly offset by a benefit of $635 million from re-measuring the Company’s net U.S. deferred tax liabilities. As of May 31, 2018, while the Company made reasonable estimates of the impact of the U.S. tax law changes, the final impact may differ from these estimates, due to, among other things, changes in its interpretations and assumptions, additional guidance and actions the Company may take.

In addition, the Company’s results for the three and nine months ended May 31, 2018 also include a net reduction to the estimated annual tax rate for the current year as a result of the U.S. tax law changes.

Investment in Chinese Pharmacy Chain GuoDa

On December 6, 2017 the Company announced that it had reached an agreement with China National Accord Medicines Corporation Ltd. to become an investor in its subsidiary Sinopharm Holding Guoda Drugstores Co., Ltd. (“GuoDa”), a leading retail pharmacy chain in China.

Following a public tender process, the Company’s bid met all the requirements set by the seller to acquire a 40 percent equity interest in GuoDa worth approximately $432 million translated using spot rate at May 31, 2018. The transaction is subject to regulatory review and approval, and other customary closing conditions. Upon completion, the Company will account for this equity investment using the equity method of accounting.

EXIT AND DISPOSAL ACTIVITIES

Store Optimization Program

On October 24, 2017, the Company’s Board of Directors approved a plan to implement a program (the “Store Optimization Program”) to optimize store locations within the Company’s Retail Pharmacy USA segment upon completion of the acquisition of certain stores and related assets from Rite Aid. The Store Optimization Program includes plans to close approximately 600 stores and related assets across the U.S. and is expected to result in cost savings of approximately $300 million per year to be fully delivered by the end of fiscal 2020. The actions under the Store Optimization Program commenced in March 2018 and are expected to take place over an 18 month period.

- 32 -

The Company currently estimates that it will recognize cumulative pre-tax charges to its GAAP financial results of approximately $450 million, including costs associated with lease obligations and other real estate costs, employee severance and other exit costs. The Company expects to incur pre-tax charges of approximately $270 million for lease obligations and other real estate costs and approximately $180 million for employee severance and other exit costs. The Company estimates that substantially all of these cumulative pre-tax charges will result in cash expenditures.

The Company has recognized cumulative pre-tax charges to its financial results in accordance with generally accepted accounting principles in the United States of America ("GAAP") of $24 million, which were recorded within selling, general, and administrative expenses. These charges included $2 million related to lease obligations and other real estate costs and $22 million in employee severance and other exit costs.

Store Optimization Program charges are recognized as the costs are incurred over time in accordance with GAAP. The Company treats charges related to the Store Optimization Program as special items impacting comparability of results in its quarterly earnings disclosures.

The amounts and timing of all estimates are subject to change until finalized. The actual amounts and timing may vary materially based on various factors. See “cautionary note regarding forward-looking statements” below.

AMERISOURCEBERGEN CORPORATION RELATIONSHIP

As of May 31, 2018, the Company owned 56,854,867 AmerisourceBergen common shares representing approximately 26% of the outstanding AmerisourceBergen common stock, and had designated one member of AmerisourceBergen’s board of directors. As of May 31, 2018, the Company can acquire up to an additional 8,398,752 AmerisourceBergen shares in the open market and thereafter designate another member of AmerisourceBergen’s board of directors, subject in each case to applicable legal and contractual requirements. The amount of permitted open market purchases is subject to increase or decrease in certain circumstances.

Effective March 18, 2016, the Company began accounting for the investment in AmerisourceBergen using the equity method of accounting, subject to a two-month reporting lag, with the net earnings attributable to the investment being classified within the operating income of the Pharmaceutical Wholesale segment. See note 5, equity method investments, to the Consolidated Condensed Financial Statements for further information.

WALGREENS BOOTS ALLIANCE RESULTS OF OPERATIONS

Net earnings attributable to Walgreens Boots Alliance for the three months ended May 31, 2018increased 15.5% to $1.3 billion compared with the prior year period, while diluted net earnings per share increased 26.2% to $1.35 compared with the prior year period. The increases in net earnings and diluted net earnings per share for the three month period ended May 31, 2018 primarily reflect costs related to the Company's Cost Transformation Program in the prior year period and a lower effective tax rate in the current period. Diluted net earnings per share was also positively affected by a lower number of shares outstanding compared to the prior year period. Net earnings and diluted net earnings per share were each positively impacted by 1.0 percentage points as a result of currency translation.

Net earnings attributable to Walgreens Boots Alliance for the nine months ended May 31, 2018increased 7.2% to $3.5 billion compared with the prior year period, while diluted net earnings per share increased16.2% to $3.51 compared with the prior year period. The increases in net earnings and diluted net earnings per share for the nine month period ended May 31, 2018 primarily reflect the effects of the Cost Transformation Program in the prior year period, partially offset by impairment of the Company's equity method investment in Guangzhou Pharmaceuticals Corporation in the nine months ended May 31, 2018. Diluted net earnings per share was also positively affected by a lower number of shares outstanding compared to the prior year period. Net earnings and diluted net earnings per share were positively impacted by 0.9 percentage points and 1.0 percentage points respectively, as a result of currency translation.

Other income (expense) for the three months ended May 31, 2018 was an expense of $4 million as compared to an expense of $8 million for the three months ended May 31, 2017. Other income (expense) for the nine months ended May 31, 2018 was an expense of $132 million, which primarily reflects the impairment of the Company’s equity method investment in Guangzhou Pharmaceuticals, as compared to an expense of $22 million, for the nine months ended May 31, 2017.

Interest was a net expense of $157 million and $457 million for the three and nine months ended May 31, 2018, respectively, compared to $155 million and $500 million in the three and nine months ended May 31, 2017, respectively. For the nine months ended May 31, 2018 the decrease is primarily as a result of the redemption of certain notes in June 2017 pursuant to the special mandatory redemption terms of the indenture governing such notes.

The effective tax rate for the three and nine months ended May 31, 2018 was 7.6% and 19.4% respectively, compared to 12.4% and 16.2% for the three and nine months ended May 31, 2017. For the three months endedMay 31, 2018, the decrease in the effective tax rate was due to the impact of the U.S. tax law changes enacted in December 2017, including the company’s estimated accrual for transition tax, which was updated in the quarter. For the nine months ended May 31, 2018, the increase in the effective tax rate reflects the Company’s estimated accrual for transition tax. A provisional net tax benefit of $140 million and net expense of $44 million was recorded during the three and nine months ended May 31, 2018, respectively, as a result of U.S. tax law changes enacted in December 2017. In addition, the Company’s results for the nine months ended May 31, 2018 also include a net reduction to the Company’s estimated annual tax rate for the current year as a result of the U.S. tax law changes.

Adjusted diluted net earnings per share (Non-GAAP measure)

Adjusted net earnings attributable to Walgreens Boots Alliance for the three months ended May 31, 2018increased 5.6% to $1.5 billion, compared with the year-ago quarter. Adjusted diluted net earnings per share increased 15.0% to $1.53, compared with the year-ago quarter. Adjusted net earnings and adjusted diluted net earnings per share were each positively impacted by 1.0 percentage points and 1.5 percentage points respectively, as a result of currency translation.

Excluding the impact of currency translation, the increase in adjusted net earnings and adjusted diluted net earnings per share for the three months ended May 31, 2018 reflects the impact of the U.S. tax law changes. Adjusted diluted net earnings per share was also positively affected by a lower number of shares outstanding compared to the prior year period.

Adjusted net earnings attributable to Walgreens Boots Alliance for the nine months ended May 31, 2018increased 10.2% to $4.5 billion, compared with the year-ago period. Adjusted diluted net earnings per share increased 19.8% to $4.54, compared with the year-ago period. Adjusted net earnings and adjusted diluted net earnings per share were positively impacted by 1.1 percentage points and 1.3 percentage points, respectively, as a result of currency translation.

Excluding the impact of currency translation, the increase in adjusted net earnings and adjusted diluted net earnings per share for the nine months ended May 31, 2018 primarily reflects the impact of the U.S. tax law changes and increased adjusted operating income. Adjusted diluted net earnings per share was also positively affected by a lower number of shares outstanding compared to the prior year period. See “--Non-GAAP Measures” below for a reconciliation to the most directly comparable GAAP measure.

Sales for the three months ended May 31, 2018 and 2017

Retail Pharmacy USA division’s sales for the three months ended May 31, 2018increased by 15.0% to $25.9 billion. Sales in comparable stores decreased 1.2% compared with the year-ago quarter.

Pharmacy sales increased by 19.3% for the three months ended May 31, 2018 and accounted for 72.5% of the division’s sales. The increase in the current quarter is mainly due to higher prescription volumes from the acquisition of Rite Aid stores and from central specialty and mail following the formation of AllianceRx Walgreens Prime. In the year-ago quarter, pharmacy sales increased10.3% and accounted for 69.9% of the division’s sales. Comparable pharmacy sales were unchanged for the three months ended May 31, 2018, compared to an increase of 5.8% in the year-ago quarter. Brand inflation was offset by reimbursement pressure and generics which had a negative impact on comparable pharmacy sales growth. The effect of generic drugs, which have a lower retail price, replacing brand name drugs reduced prescription sales by 1.1% in the three months ended May 31, 2018 compared to a reduction of 2.6% in the year-ago quarter. On division sales, this effect was a reduction of 0.7% for the three months ended May 31, 2018 compared to a reduction of 1.6% for the year-ago quarter. The total number of prescriptions (including immunizations) filled for the three months ended May 31, 2018 was 215.2 million compared to 196.0 million in the year-ago quarter. Prescriptions (including immunizations) filled adjusted to 30-day equivalents were 285.2 million in the three months ended May 31, 2018 compared to 255.2 million in the year-ago quarter.

Retail sales increased 5.2% for the three months ended May 31, 2018 and were 27.5% of the division’s sales. In the year-ago quarter, retail sales decreased 1.8% and represented 30.1% of the division’s sales. The increase in the current quarter is mainly due to sales from the acquired Rite Aid stores. Comparable retail sales decreased 3.8% in the three months ended May 31, 2018 compared to a decrease of 0.4% in the year-ago quarter.

Operating income for the three months ended May 31, 2018 and 2017

²  Comparable stores are defined as those that have been open for at least twelve consecutive months without closure for seven or more consecutive days and without a major remodel or a natural disaster in the past twelve months. Relocated and acquired stores are not included as comparable stores for the first twelve months after the relocation or acquisition. The method of calculating comparable sales varies across the industries in which the Company operates. As a result, our method of calculating comparable sales may not be the same as other companies’ methods.

³  The Company presents certain information related to current period operating results in “constant currency,” which is a non-GAAP financial measure. These amounts are calculated by translating current period results at the foreign currency exchange rates used in the comparable period in the prior year. The Company presents such constant currency financial information because it has significant operations outside of the United States reporting in currencies other than the U.S. dollar and this presentation provides a framework to assess how its business performed excluding the impact of foreign currency exchange rate fluctuations.

LIQUIDITY AND CAPITAL RESOURCES

Cash and cash equivalents were $1.8 billion (including $730 million in non-U.S. jurisdictions) as of May 31, 2018, compared to $12.3 billion (including $2.2 billion in non-U.S. jurisdictions) at May 31, 2017. Short-term investment objectives are primarily to minimize risk and maintain liquidity. To attain these objectives, investment limits are placed on the amount, type and issuer of securities. Investments are principally in U.S. Treasury money market funds and AAA-rated money market funds.

Our long-term capital policy is to maintain a strong balance sheet and financial flexibility; reinvest in our core strategies; invest in strategic opportunities that reinforce our core strategies and meet return requirements; and return surplus cash flow to stockholders in the form of dividends and share repurchases over the long term. In June 2018, the Company’s Board of Directors reviewed and refined the Company’s dividend policy to set forth the Company’s current intention to increase its dividend each year.

Cash provided by operations and the issuance of debt are the principal sources of funds for expansion, investments, acquisitions, remodeling programs, dividends to shareholders and stock repurchases. Net cash provided by operating activities for the nine months ended May 31, 2018 was $5.4 billion, compared to $5.2 billion for the year-ago period. The $148 millionincrease in cash provided by operating activities was primarily due to lower cash outflows from income taxes paid and accrued expenses and other liabilities partially offset by higher cash outflows from accounts receivable, net and trade accounts payable. Changes in income taxes paid are mainly due to the impact of U.S. tax law changes. Changes in accrued expenses and other liabilities are mainly driven by the timing of payments. Changes in accounts receivable, net are mainly driven by increased sales in Retail Pharmacy USA and timing. Changes in trade accounts payable are mainly driven by the timing of payments resulting from term changes on pharmaceutical related purchases in the year ago period partially offset by increased purchases in Retail Pharmacy USA.

Net cash used for investing activities was $5.1 billion for the nine months ended May 31, 2018, compared to $452 million used in the year-ago period. Business acquisitions in the nine months ended May 31, 2018 were $4.2 billion compared to $63 million for the year-ago period.

For the nine months ended May 31, 2018, additions to property, plant and equipment were $983 million compared to $912 million in the year-ago period. Capital expenditures by reporting segment were as follows:

	Nine months ended May 31,
	2018		2017
Retail Pharmacy USA	$	726	$	556
Retail Pharmacy International	182		279
Pharmaceutical Wholesale	75		77
Total	$	983	$	912

Significant capital expenditures primarily relate to investments in our stores and information technology projects.

Additionally, investing activities for the nine months ended May 31, 2018 did not include any proceeds related to sale-leaseback transactions, compared to $436 million in the year-ago period.

Net cash used for financing activities for the nine months ended May 31, 2018 was $1.8 billion, compared to net cash used of $2.3 billion in the year-ago period. The Company repurchased shares as part of the June 2017 stock repurchase program described below and to support the needs of the employee stock plans totaling $2.5 billion in the nine months ended May 31, 2018, compared to $1.5 billion in shares repurchased in the nine months ended May 31, 2017. Proceeds related to employee stock plans were $118 million during the nine months ended May 31, 2018, compared to $174 million for the nine months ended May 31, 2017. Cash dividends paid were $1.3 billion during the nine months ended May 31, 2018, compared to $1.2 billion for the same period a year ago.

The Company believes that cash flow from operations, availability under our existing credit facilities and arrangements, current cash and investment balances and our ability to obtain other financing, if necessary, will provide adequate cash funds for our foreseeable working capital needs, capital expenditures at existing facilities, pending acquisitions (including the acquisition of Rite Aid assets), dividend payments and debt service obligations for at least the next 12 months. Our cash requirements are subject to change as business conditions warrant and opportunities arise. The timing and size of any new business ventures or acquisitions that the Company may complete may also impact our cash requirements.

Stock repurchase programs

In April 2017, Walgreens Boots Alliance authorized a stock repurchase program (the “April 2017 stock repurchase program”), which authorized the repurchase of up to $1.0 billion of Walgreens Boots Alliance common stock prior to the program’s expiration on December 31, 2017. In May 2017, the Company completed the April 2017 stock repurchase program, purchasing 11.8 million shares. In June 2017, Walgreens Boots Alliance authorized a new stock repurchase program, which authorized the repurchase of up to $5.0 billion of Walgreens Boots Alliance common stock prior to the program’s expiration on August 31, 2018, which authorization was increased by an additional $1.0 billion in October 2017 (as expanded, the “June 2017 stock repurchase program”). During fiscal 2017, the Company purchased 47.2 million shares at a total cost of $3.8 billion under the June 2017 stock repurchase program. During the nine months ended May 31, 2018, the Company purchased 30.3 million shares at a total cost of $2.2 billion. The June 2017 stock repurchase program was completed in October 2017. In June 2018, Walgreens Boots Alliance authorized a new stock repurchase program, which authorized the repurchase of up to $10.0 billion of Walgreens Boots Alliance common stock, which program has no specified expiration date. The Company determines the timing and amount of repurchases, including repurchases to offset anticipated dilution from equity incentive plans, based on our assessment of various factors, including prevailing market conditions, alternate uses of capital, liquidity and the economic environment. The Company has repurchased, and may from time to time in the future repurchase, shares on the open market through Rule 10b5-1 plans, which enable us to repurchase shares at times when the Company otherwise might be precluded from doing so under insider trading laws.

Commercial paper

The Company periodically borrows under its commercial paper program and may continue to borrow under it in future periods. The Company had $1.0 billion commercial paper borrowings outstanding as of May 31, 2018 and there were no commercial paper borrowings outstanding as of August 31, 2017. The Company had average daily short-term borrowings of $1.4 billion of commercial paper outstanding at a weighted average interest rate of 2.00% for the nine months ended May 31, 2018 and no activity under its commercial paper program for the nine months ended May 31, 2017.

Financing actions

On November 10, 2014, Walgreens Boots Alliance and Walgreens entered into a term loan credit agreement with the lenders party thereto (the “2014 Term Loan Agreement”), which provided Walgreens Boots Alliance and Walgreens with the ability to borrow up to £1.45 billion on an unsecured basis. On August 30, 2017, Walgreens Boots Alliance used available cash to repay in full all outstanding loans and obligations under the 2014 Term Loan Agreement, which, as of such date, consisted of the remaining unamortized amount of £1.41 billion ($1.83 billion at the August 31, 2017 spot rate of $1.295 to £1) aggregate principal amount of outstanding loans together with accrued interest thereon through, but excluding, the payment date, and the 2014 Term Loan Agreement terminated in accordance with its terms.

On November 10, 2014, Walgreens Boots Alliance and Walgreens entered into a five-year unsecured, multicurrency revolving credit agreement with the lenders party thereto (the “2014 Revolving Credit Agreement”), which has available credit of $3.0 billion, of which $500 million is available for the issuance of letters of credit. Borrowings under the 2014 Revolving Credit Agreement bear interest at a fluctuating rate per annum equal to, at Walgreens Boots Alliance’s option, the alternate base rate or the reserve adjusted LIBOR, in each case, plus an applicable margin calculated based on Walgreens Boots Alliance’s credit ratings. As of May 31, 2018 and 2017, there were no borrowings or letters of credit issued pursuant to the 2014 Revolving Credit Agreement.

On November 18, 2014, Walgreens Boots Alliance issued several series of unsecured, unsubordinated notes totaling $8.0 billion, with maturities ranging from 2016 to 2044. All such notes have fixed interest rates, with the exception of the $750 million floating rate notes due 2016, which were repaid in full in May 2016 and which had a floating rate based on the three month LIBOR plus a fixed spread of 45 basis points. On August 28, 2017, Walgreens Boots Alliance redeemed in full its $750 million 1.750% notes due 2017 at a make-whole redemption price.

On June 1, 2016, Walgreens Boots Alliance issued in an underwritten public offering $1.2 billion of 1.750% notes due 2018 (the “2018 notes”), $1.5 billion of 2.600% notes due 2021 (the “2021 notes”), $0.8 billion of 3.100% notes due 2023 (the “2023 notes”), $1.9 billion of 3.450% notes due 2026 (the “2026 notes”) and $0.6 billion of 4.650% notes due 2046 (the “2046 notes”). Because the merger with Rite Aid was not consummated on or prior to June 1, 2017, the 2018 notes, the 2021 notes and the 2023 notes were redeemed on June 5, 2017 under the special mandatory redemption terms of the indenture governing such notes. The 2026 notes and 2046 notes remain outstanding in accordance with their respective terms.

On February 1, 2017, Walgreens Boots Alliance entered into a $1.0 billion revolving credit facility (as amended, the “February 2017 Revolving Credit Agreement”) with the lenders from time to time party thereto and, on August 1, 2017, Walgreens Boots

- 47 -

Alliance entered into an amendment agreement thereto. The terms and conditions of the February 2017 Revolving Credit Agreement were unchanged by the amendment other than the extension of the facility termination date to the earlier of (a) January 31, 2019 and (b) the date of termination in whole of the aggregate commitments provided by the lenders thereunder. Borrowings under the February 2017 Revolving Credit Agreement will bear interest at a fluctuating rate per annum equal to, at Walgreens Boots Alliance’s option, the alternate base rate or the reserve adjusted Eurocurrency rate, in each case, plus an applicable margin calculated based on Walgreens Boots Alliance’s credit ratings. As of May 31, 2018, there were no borrowings under the February 2017 Revolving Credit Agreement.

On August 24, 2017, Walgreens Boots Alliance entered into a $1.0 billion revolving credit agreement with the lenders from time to time party thereto (the “August 2017 Revolving Credit Agreement”) and a $1.0 billion term loan credit agreement with Sumitomo Mitsui Banking Corporation (the “2017 Term Loan Credit Agreement” and together with the August 2017 Revolving Credit Agreement, the “August 2017 Credit Agreements”). The August 2017 Revolving Credit Agreement is an unsecured revolving credit facility with a facility termination date of the earlier of (a) January 31, 2019, subject to any extension thereof pursuant to the terms of the August 2017 Revolving Credit Agreement and (b) the date of termination in whole of the aggregate commitments provided by the lenders thereunder. As of May 31, 2018, there were no borrowings outstanding under the August 2017 Revolving Credit Agreement. The 2017 Term Loan Credit Agreement is an unsecured “multi-draw” term loan facility maturing on March 30, 2019. As of May 31, 2018, Walgreens Boots Alliance had $1.0 billion of borrowings outstanding under the 2017 Term Loan Credit Agreement, and no additional commitments were available. Borrowings under the August 2017 Credit Agreements will bear interest at a fluctuating rate per annum equal to, at Walgreens Boots Alliance’s option, the alternate base rate or the Eurocurrency rate, in each case, plus an applicable margin calculated based on Walgreens Boots Alliance’s credit ratings.

From time to time, the Company may also enter into other credit facilities, including in March 2018, a $350 million short-term unsecured revolving credit facility which was undrawn as of May 31, 2018.

Debt covenants

Each of the Company’s credit facilities described above contain a covenant to maintain, as of the last day of each fiscal quarter, a ratio of consolidated debt to total capitalization not to exceed 0.60:1.00. The credit facilities contain various other customary covenants. As of May 31, 2018, the Company was in compliance with all such applicable covenants.

Credit ratings

As of June 27, 2018, the credit ratings of Walgreens Boots Alliance were:

Rating agency	Long-term debt rating	Commercial paper rating	Outlook
Fitch	BBB	F2	Stable
Moody’s	Baa2	P-2	Stable
Standard & Poor’s	BBB	A-2	Stable

In assessing our credit strength, each rating agency considers various factors including our business model, capital structure, financial policies and financial performance. There can be no assurance that any particular rating will be assigned or maintained. Our credit ratings impact our borrowing costs, access to capital markets and operating lease costs. The rating agency ratings are not recommendations to buy, sell or hold our debt securities or commercial paper. Each rating may be subject to revision or withdrawal at any time by the assigning rating agency and should be evaluated independently of any other rating.

AmerisourceBergen relationship

Pursuant to our arrangements with AmerisourceBergen, the Company has the right, but not the obligation, to purchase a minority equity position in AmerisourceBergen over time as described under “--AmerisourceBergen Corporation relationship” above. Subject to applicable legal and contractual requirements, share purchases may be made from time to time in open market transactions or pursuant to instruments and plans complying with Rule 10b5-1.

OFF-BALANCE SHEET ARRANGEMENTS

The Company does not have any unconsolidated special purpose entities and, except as described herein, the Company does not have significant exposure to any off-balance sheet arrangements. The term “off-balance sheet arrangement” generally means any transaction, agreement or other contractual arrangement to which an entity unconsolidated with us is a party, under which the Company has: (i) any obligation arising under a guarantee contract, derivative instrument or variable interest; or (ii) a retained or contingent interest in assets transferred to such entity or similar arrangement that serves as credit, liquidity or market risk support for such assets.

- 48 -

As of May 31, 2018, the Company has issued $200 million in letters of credit, primarily related to insurance obligations. The Company also had $45 million of guarantees to various suppliers outstanding as of May 31, 2018. The Company remains secondarily liable on 71 leases. The maximum potential undiscounted future payments related to these leases was $311 million as of May 31, 2018.

CONTRACTUAL OBLIGATIONS AND COMMITMENTS

Other than our obligations under the amended and restated asset purchase agreement with Rite Aid and the transactions contemplated thereby, there have been no material changes, outside of the ordinary course of business, in our outstanding contractual obligations disclosed in the Walgreens Boots Alliance Annual Report on Form 10-K for the year ended August 31, 2017.

CRITICAL ACCOUNTING POLICIES

The Consolidated Financial Statements are prepared in accordance with GAAP and include amounts based on management’s prudent judgments and estimates. Actual results may differ from these estimates. Management believes that any reasonable deviation from those judgments and estimates would not have a material impact on our consolidated financial position or results of operations. To the extent that the estimates used differ from actual results, however, adjustments to the statement of earnings and corresponding balance sheet accounts would be necessary. These adjustments would be made in future periods. For a discussion of our significant accounting policies, please see the Walgreens Boots Alliance Annual Report on Form 10-K for the fiscal year ended August 31, 2017. Some of the more significant estimates include business combinations, goodwill and indefinite-lived intangible asset impairment, vendor allowances, liability for closed locations, cost of sales and inventory, equity method investments, pension and postretirement benefits and income taxes. There have been no significant changes in those accounting policies.

NEW ACCOUNTING PRONOUNCEMENTS

A discussion of new accounting pronouncements is described in note 17, new accounting pronouncements in Item 1. Consolidated Condensed Financial Statements (Unaudited) of this Quarterly Report on Form 10-Q and is incorporated herein by reference.

Item 3. Quantitative and qualitative disclosure about market risk

Interest rate risk

The Company is exposed to interest rate volatility with regard to existing debt issuances. Primary exposures include U.S. Treasury rates, LIBOR and commercial paper rates. From time to time, the Company uses interest rate swaps and forward-starting interest rate swaps to hedge our exposure to the impact of interest rate changes on existing debt and future debt issuances respectively, to reduce the volatility of our financing costs and, based on current and projected market conditions, achieve a desired proportion of fixed versus floating-rate debt. Generally under these swaps, the Company agrees with a counterparty to exchange the difference between fixed-rate and floating-rate interest amounts based on an agreed upon notional principal amount.

Information regarding our transactions are set forth in note 8, financial instruments, to the Consolidated Condensed Financial Statements. These financial instruments are sensitive to changes in interest rates. On May 31, 2018, the Company had no material long-term debt obligations that had floating interest rates. The amounts exclude the impact of any associated derivative contracts.

Foreign currency exchange rate risk

The Company is exposed to fluctuations in foreign currency exchange rates, primarily with respect to the British pound sterling and Euro,and certain other foreign currencies, which may affect our net investment in foreign subsidiaries and may cause fluctuations in cash flows related to foreign denominated transactions. The Company is also exposed to the translation of foreign currency earnings to the U.S. dollar. The Company enters into foreign currency forward contracts to hedge against the effect of exchange rate fluctuations on non-functional currency cash flows. These transactions are almost exclusively less than 12 months in maturity. In addition, the Company enters into foreign currency forward contracts that are not designated in hedging relationships to offset, in part, the impacts of certain intercompany activities (primarily associated with intercompany financing transactions).

Our foreign currency derivative instruments are sensitive to changes in exchange rates. A hypothetical 1% change in foreign currency exchange rates versus the U.S. dollar would change the fair value of the foreign currency derivatives held as of May 31, 2018 by approximately $14 million. The foreign currency derivatives are intended to partially hedge anticipated transactions, foreign currency trade payables and receivables, and net investments in foreign subsidiaries.

Item 4. Controls and procedures

Evaluation of disclosure controls and procedures

Management conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this Form 10-Q. The controls evaluation was conducted under the supervision and with the participation of the Company’s management, including its Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”). As of the end of the period covered by this report, the Company had acquired 1,932 stores from Rite Aid. The scope of management's assessment of the effectiveness of the Company's disclosure controls and procedures did not include the internal controls over financial reporting of the acquired Rite Aid stores. This exclusion is in accordance with the SEC staff's general guidance that an assessment of a recently acquired business may be omitted from the scope of management's assessment for one year following the acquisition. Based upon the controls evaluation, our CEO and CFO have concluded that, as of the end of the period covered by this report, our disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified by the SEC, and that such information is accumulated and communicated to management, including the CEO and CFO, as appropriate to allow timely decisions regarding required disclosure.

Changes in internal control over financial reporting

In connection with the evaluation pursuant to Exchange Act Rule 13a-15(d) of the Company’s internal control over financial reporting (as defined in Exchange Act Rule 13a-15(f)) by the Company’s management, including its CEO and CFO, no changes during the three months ended May 31, 2018 were identified that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting. As a result of the acquisition of Rite Aid stores, the Company has incorporated internal controls over significant processes specific to the acquisition that it believes to be appropriate and necessary in consideration of the level of related integration. As the post-closing integration continues, the Company will continue to review such internal controls and processes and may take further steps to integrate such controls and processes with those of the Company.

Inherent limitations on effectiveness of controls

Our management, including the CEO and CFO, do not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. The design of a

- 51 -

control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Further, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Controls can also be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Projections of any evaluation of controls effectiveness to future periods are subject to risks. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures.

Part II.  Other Information

Item 1. Legal proceedings

The information in response to this item is incorporated herein by reference to note 10, commitments and contingencies of the Consolidated Condensed Financial Statements of this Quarterly Report.

Item 1A. Risk factors

In addition to the other information set forth in this report, you should carefully consider the factors discussed in Item 1A. “Risk factors” in the Walgreens Boots Alliance Annual Report on Form 10-K for the fiscal year ended August 31, 2017 and Quarterly Report on Form 10-Q for the fiscal quarter ended November 30, 2017, which could materially affect our business, financial condition or future results.

Item 2. Unregistered sales of equity securities and use of proceeds

(c) There were no purchases of the Company’s common stock during the quarter ended May 31, 2018 and as of that date no shares were authorized to be repurchased under a publicly announced plan. In June 2018, Walgreens Boots Alliance authorized a new stock repurchase program, which authorized the repurchase of up to $10.0 billion of Walgreens Boots Alliance common stock, which program has no specified expiration date. Subject to applicable law, share purchases may be made from time to time in open market transactions, privately negotiated transactions including accelerated share repurchase agreements, or pursuant to instruments and plans complying with Rule 10b5-1.

Item 6. Exhibits

The agreements included as exhibits to this report are included to provide information regarding their terms and not intended to provide any other factual or disclosure information about the Company or the other parties to the agreements. The agreements may contain representations and warranties by each of the parties to the applicable agreement that were made solely for the benefit of the other parties to the applicable agreement, and:

• should not in all instances be treated as categorical statements of fact, but rather as a way of allocating the risk to one of the parties if those statements prove to be inaccurate;

Basis of presentation

The Consolidated Condensed Financial Statements of Walgreens Boots Alliance, Inc. (“Walgreens Boots Alliance” or the “Company”) included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission regarding interim financial reporting. The Consolidated Condensed Financial Statements include all subsidiaries in which the Company holds a controlling interest. Investments in less than majority-owned subsidiaries in which the Company does not have a controlling interest, but does have significant influence, are accounted for as equity method investments. All intercompany transactions have been eliminated.

The Consolidated Condensed Financial Statements included herein are unaudited. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) have been condensed or omitted pursuant to such rules and regulations, although the Company believes that the disclosures are adequate to make the information presented not misleading. These unaudited Consolidated Condensed Financial Statements should be read in conjunction with the audited financial statements and the notes thereto included in the Walgreens Boots Alliance Annual Report on Form 10-K for the fiscal year ended August 31, 2017.

In the opinion of management, the unaudited Consolidated Condensed Financial Statements for the interim periods presented include all adjustments (consisting only of normal recurring adjustments) necessary to present a fair statement of the results for such interim periods. 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. With respect to the Company’s Retail Pharmacy USA segment, the positive impact on gross profit margins and gross profit dollars typically has been significant in the first several months after a generic version of a drug is first allowed to compete with the branded version, which is generally referred to as a “generic conversion”. In any given year, the number of major brand name drugs that undergo a conversion from branded to generic status can increase or decrease, which can have a significant impact on the Company’s Retail Pharmacy USA segment’s sales, gross profit margins and gross profit dollars making the Company’s operations or net earnings for any period incomparable.

Acquisitions

Acquisition of certain Rite Aid Corporation (“Rite Aid”) assets

On September 19, 2017, the Company announced that it had secured regulatory clearance for an amended and restated asset purchase agreement to purchase 1,932 stores, three distribution centers and related inventory from Rite Aid for $4.375 billion in cash and other consideration. The purchases of these stores have been accounted for as business combinations and occurred in waves during fiscal 2018. The Company purchased 390 stores for total cash consideration of $820 million for the three months ended May 31, 2018 and 1,932 stores for total cash consideration of $4.2 billion for the nine months ended May 31, 2018. The transition of the three distribution centers and related inventory is expected to begin during fiscal 2019 and remains subject to closing conditions set forth in the amended and restated asset purchase agreement.

As of May 31, 2018, the Company had not completed the analysis to assign fair values to all tangible and intangible assets acquired and therefore the purchase price allocation has not been finalized. The preliminary purchase price allocation will be subject to further refinement and may result in material changes. These changes will primarily relate to the allocation of consideration and the fair value assigned to all tangible and intangible assets acquired and identified. During the three months ended May 31, 2018, the Company recorded certain measurement period adjustments to identified assets acquired and liabilities assumed based on additional information regarding such assets and liabilities, which did not have a material impact on the purchase price allocation. The following table summarizes the consideration for the purchases and the preliminary amounts of identified assets acquired and liabilities assumed as of the nine months ended May 31, 2018.

Consideration	$	4,330
Identifiable assets acquired and liabilities assumed
Inventories	$	1,291
Property, plant and equipment	494
Intangible assets	2,028
Accrued expenses and other liabilities	(54		)
Deferred income taxes	5
Other non-current liabilities	(795		)
Total identifiable net assets	2,969
Goodwill	$	1,361

The preliminary identified definite-lived intangible assets were as follows:

Definite-lived intangible assets	Weighted-average useful life (in years)	Amount (in millions)
Customer relationships	12	$	1,850
Favorable lease interests	6	158
Trade names and trademarks	2	20
Total		$	2,028

Consideration includes cash of $4,157 million and the fair value of the option granted to Rite Aid to become a member of the Company’s group purchasing organization, Walgreens Boots Alliance Development GmbH. The fair value for this option was determined using the income approach methodology.  The fair value estimates are based on the market compensation for such services and appropriate discount rate, as relevant, that market participants would consider when estimating fair values.

The goodwill of $1,361 million arising from the business combinations primarily reflects the expected operational synergies and cost savings generated from the Store Optimization Program as well as the expected growth from new customers. See note 3, exit and disposal activities, for additional information. The goodwill was allocated to the Retail Pharmacy USA segment. Substantially all of the goodwill recognized is expected to be deductible for income tax purposes.

The fair value for customer relationships was determined using the multi-period excess earnings method, a form of the income approach. Real property fair values were determined using primarily the income approach and sales comparison approach. The fair value measurements of the intangible assets are based on significant inputs not observable in the market, and thus represent Level 3 measurements. The fair value estimates for the intangible assets are based on projected discounted cash flows, historical and projected financial information, and attrition rates, as relevant, that market participants would consider when estimating fair values.

The following table presents supplemental unaudited condensed pro forma consolidated sales for the three and nine months ended May 31,2018 and 2017 as if all 1,932 stores acquired under the amended and restated asset purchase agreement had occurred on September 1, 2016. Pro forma net earnings of the Company, assuming these purchases had occurred at the beginning of each period presented, would not be materially different from the results reported. See note 3, exit and disposal activities, for additional information. The unaudited condensed pro forma information has been prepared for comparative purposes only and is not intended to be indicative of what the Company’s results would have been had the purchases occurred at the beginning of the periods presented or results which may occur in the future.

AllianceRx Walgreens Prime

On March 31, 2017, Walgreens Boots Alliance and pharmacy benefit manager Prime Therapeutics LLC (“Prime”) closed a transaction to form a combined central specialty pharmacy and mail services company AllianceRx Walgreens Prime, as part of a strategic alliance. AllianceRx Walgreens Prime is consolidated by Walgreens Boots Alliance and reported within the Retail Pharmacy USA division in its financial statements. The Company accounted for this acquisition of Prime’s specialty pharmacy and mail services business as a business combination involving noncash purchase consideration of $720 million consisting of the issuance of an equity interest in AllianceRx Walgreens Prime.

The Company has completed the purchase accounting for the AllianceRx Walgreens Prime transaction. The following table summarizes the consideration for the acquisition and the amounts of identified assets acquired and liabilities assumed at the date of the transaction (in millions).

Consideration	$	720
Identifiable assets acquired and liabilities assumed
Accounts receivable	$	217
Inventories	149
Property, plant and equipment	11
Intangible assets	331
Trade accounts payable	(90		)
Accrued expenses and other liabilities	(1		)
Total identifiable net assets	617
Goodwill	$	103

The identified intangible assets primarily include purchasing and payer contracts. These contracts are estimated to have a weighted average useful life of 15 years. The goodwill of $103 million arising from the transaction consists of expected purchasing synergies, operating efficiencies by benchmarking performance and applying best practices across the combined company, consolidation of operations, reductions in selling, general and administrative expenses and combining workforces. Substantially all of the goodwill recognized is not expected to be deductible for income tax purposes.

In accordance with ASC Topic 810, Consolidation, the noncontrolling interest was recognized based on its proportionate interest in the identifiable net assets of AllianceRx Walgreens Prime. The difference between the carrying amount of the noncontrolling interest and the fair value recognized as consideration in the business combination is recognized as additional paid in capital.

Restructuring and Related Activities [Abstract]

Exit and disposal activities

Exit and disposal activities

On October 24, 2017, the Company’s Board of Directors approved a plan to implement a program (the “Store Optimization Program”) as part of an initiative to optimize store locations within the Company’s Retail Pharmacy USA segment upon completion of the acquisition of certain stores and related assets from Rite Aid. The Store Optimization Program includes plans to close approximately 600 stores and related assets across the U.S. The actions under the Store Optimization Program commenced in March 2018 and are expected to take place over an 18 month period.

The Company currently estimates that it will recognize cumulative pre-tax charges to its GAAP financial results of approximately $450 million, including costs associated with lease obligations and other real estate costs, employee severance and other exit costs. The Company expects to incur pre-tax charges of approximately $270 million for lease obligations and other real estate costs and approximately $180 million for employee severance and other exit costs. The Company estimates that substantially all of these cumulative pre-tax charges will result in cash expenditures.

Costs related to the Store Optimization Program, which were primarily recorded in selling, general and administrative expenses for the Company's Retail Pharmacy USA segment included in the three and nine months ended May 31, 2018, are as follows (in millions):

Three months ended May 31, 2018

On April 8, 2015, the Walgreens Boots Alliance Board of Directors approved a plan to implement a restructuring program (the “Cost Transformation Program”) as part of an initiative to reduce costs and increase operating efficiencies. The Cost Transformation Program implemented and built on the cost-reduction initiative previously announced by the Company on August 6, 2014 and included plans to close stores across the U.S.; reorganize corporate and field operations; drive operating efficiencies; and streamline information technology and other functions. The actions under the Cost Transformation Program focused primarily on the Retail Pharmacy USA segment, but included activities from all segments. The Company completed the Cost Transformation Program in the fourth quarter of fiscal 2017.

The changes in liabilities related to the Cost Transformation Program for the nine months ended May 31, 2018 include the following (in millions):

Leases [Abstract]

Operating leases

Operating 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. The Company recognizes rent expense on a straight-line basis over the term of the lease. In addition to minimum fixed rentals, some leases provide for contingent rentals based upon a portion of sales.

The Company continuously evaluates its real estate portfolio in conjunction with its capital needs. Historically, the Company has entered into several sale-leaseback transactions. For the nine months ended May 31, 2018, the Company did not record any proceeds from sale-leaseback transactions. For the nine months ended May 31, 2017, the Company recorded proceeds from sale-leaseback transactions of $436 million.

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. During the three and nine months ended May 31, 2018, the Company recorded charges of $21 million and $88 million for facilities that were closed. This compares to $25 million and $289 million for the three and nine months ended May 31, 2017. These charges are reported in selling, general and administrative expenses in the Consolidated Condensed Statements of Earnings.

The changes in reserve for facility closings and related lease termination charges primarily in other non-current liabilities, include the following (in millions):

	For the nine months ended May 31, 2018			For the twelve months ended August 31, 2017
Balance at beginning of period	$	718		$	466

As of May 31, 2018, the Company remains secondarily liable on 71 leases. The maximum potential undiscounted future payments are $311 million as of May 31, 2018.

Others	1,152		8% - 50%	1,296		8% - 50%
Total	$	6,272		$	6,320

AmerisourceBergen investment

As of May 31, 2018 and August 31, 2017, the Company owned 56,854,867 AmerisourceBergen Corporation (“AmerisourceBergen”) common shares, representing approximately 26% of the outstanding AmerisourceBergen common stock. The Company accounts for its equity investment in AmerisourceBergen using the equity method of accounting, with the net earnings attributable to the Company’s investment being classified within the operating income of its Pharmaceutical Wholesale segment. Due to the timing and availability of financial information of AmerisourceBergen, the Company accounts for this equity method investment on a financial reporting lag of two months. Equity earnings from AmerisourceBergen are reported as a separate line in the Consolidated Condensed Statements of Earnings. The level 1 fair market value of the Company’s equity investment in AmerisourceBergen common stock at May 31, 2018 is $4.7 billion.

As of May 31, 2018, the Company’s investment in AmerisourceBergen carrying value exceeded its proportionate share of the net assets of AmerisourceBergen by $4.2 billion. This premium of $4.2 billion was recognized as part of the carrying value in the Company’s equity investment in AmerisourceBergen. The difference was primarily related to goodwill and the fair value of AmerisourceBergen intangible assets.

Other investments

The Company’s other equity method investments include its investments in Guangzhou Pharmaceuticals Corporation (“Guangzhou Pharmaceuticals”) and Nanjing Pharmaceutical Corporation Limited, the Company’s pharmaceutical wholesale investments in China; and the equity method investment retained through the sale of a majority interest in Option Care Inc. in fiscal 2015.

The Company reported $15 million of post-tax equity earnings and $21 million of post-tax equity losses from other equity method investments for the three months ended May 31, 2018 and May 31, 2017, respectively. The Company reported $42 million and $7 million of post-tax equity earnings from other equity method investments for the nine months ended May 31, 2018 and May 31, 2017, respectively. During the nine month period ended May 31, 2018, the Company recorded an impairment of $170 million in its equity interest in Guangzhou Pharmaceuticals, which was included in other income (expense) in the Consolidated Condensed Statements of Earnings. The fair value of the Company’s equity interest in Guangzhou Pharmaceuticals was determined using the proposed sale price and thus represents Level 3 measurement. During the three months ended May 31, 2018, the Company completed the sale of a 30 percent interest in Guangzhou Pharmaceuticals to its joint venture partner Guangzhou Baiyunshan Pharmaceutical Holdings resulting in a $172 million reduction in carrying value and a $8 million cumulative translation adjustment loss.

August 2017 Credit Agreements

On August 24, 2017, the Company entered into a $1.0 billion revolving credit agreement with the lenders from time to time party thereto (the “August 2017 Revolving Credit Agreement”) and a $1.0 billion term loan credit agreement with Sumitomo Mitsui Banking Corporation (the “2017 Term Loan Credit Agreement”).

The August 2017 Revolving Credit Agreement is an unsecured revolving credit facility with a facility termination date of the earlier of (a) January 31, 2019, subject to any extension thereof pursuant to the terms of the August 2017 Revolving Credit Agreement and (b) the date of termination in whole of the aggregate commitments provided by the lenders thereunder. As of May 31, 2018, there were no borrowings outstanding under the August 2017 Revolving Credit Agreement. The 2017 Term Loan Credit Agreement is an unsecured “multi-draw” term loan facility which matures on March 30, 2019.  As of May 31, 2018, Walgreens Boots Alliance had $1.0 billion of borrowings outstanding under the 2017 Term Loan Credit Agreement, and no additional commitments were available.

February 2017 Revolving Credit Agreement

On February 1, 2017, the Company entered into a $1.0 billion revolving credit facility (as amended, the “February 2017 Revolving Credit Agreement”) with the lenders from time to time party thereto and, on August 1, 2017, the Company entered into an amendment agreement thereto. The terms and conditions of the February 2017 Revolving Credit Agreement were unchanged by the amendment other than the extension of the facility termination date to the earlier of (a) January 31, 2019 and (b) the date of termination in whole of the aggregate commitments provided by the lenders thereunder. As of May 31, 2018, there were no borrowings outstanding under the February 2017 Revolving Credit Agreement.

$6.0 billion note issuance

On June 1, 2016, Walgreens Boots Alliance received net proceeds of $6.0 billion from a public offering of five series of U.S. dollar notes with varying maturities and interest rates. Because the merger with Rite Aid was not consummated on or prior to June 1, 2017, the 2018 notes, the 2021 notes and the 2023 notes were redeemed on June 5, 2017 under the special mandatory redemption terms of the indenture governing such notes. Walgreens Boots Alliance was required to redeem all of the 2018 notes, the 2021 notes and the 2023 notes then outstanding, at a special mandatory redemption price equal to 101% of the aggregate principal amount of such notes, plus accrued and unpaid interest of approximately $1 million to, but excluding, the date of redemption. The 2026 notes and 2046 notes remain outstanding in accordance with their respective terms.

Debt covenants

Each of the Company’s credit facilities contain a covenant to maintain, as of the last day of each fiscal quarter, a ratio of consolidated debt to total capitalization not to exceed 0.60:1.00. The credit facilities contain various other customary covenants.

Commercial paper

The Company periodically borrows under its commercial paper program and may borrow under it in future periods. The Company had average daily short-term borrowings of $1.4 billion of commercial paper outstanding at a weighted average interest rate of 2.00% for the nine months ended May 31, 2018. The Company had no activity under its commercial paper program for the nine months ended May 31, 2017.

The Company uses interest rate swaps to manage the interest rate exposure associated with some of its fixed-rate borrowings and designates them as fair value hedges. From time to time, the Company may use forward starting interest rate swaps to hedge interest rate exposure of some or all of its anticipated debt issuances.

The Company utilizes foreign currency forward contracts and other foreign currency derivatives to hedge significant committed and highly probable future transactions and cash flows denominated in currencies other than the functional currency of the Company or its subsidiaries. The Company has significant non-U.S. dollar denominated net investments and uses foreign currency denominated financial instruments, specifically foreign currency derivatives and foreign currency denominated debt, to hedge its foreign currency risk.

Fair value hedges

The Company holds an interest rate swap converting $250 million of its 5.250% fixed rate notes to a floating interest rate based on the six-month LIBOR in arrears plus a constant spread. The swap termination date coincides with the January 15, 2019 maturity date of the notes. This swap was designated as a fair value hedge.

The gains and losses due to changes in fair value on the swaps and on the hedged notes attributable to interest rate risk did not have a material impact on the Company’s Financial Statements. The changes in fair value of the Company’s debt that was swapped from fixed to variable rate and designated as fair value hedges are included in long-term debt on the Consolidated Condensed Balance Sheets (see note 7, debt).

Derivatives not designated as hedges

The Company enters into derivative transactions that are not designated as accounting hedges. These derivative instruments are economic hedges of foreign currency risks. The income and (expense) due to changes in fair value of these derivative instruments were recognized in earnings as follows (in millions):

		Three months ended May 31,					Nine months ended May 31,

Foreign currency forwards	Other income (expense)	3		(1		)	36			(15		)

Derivatives credit risk

Counterparties to derivative financial instruments expose the Company to credit-related losses in the event of counterparty nonperformance, and the Company regularly monitors the credit worthiness of each counterparty.

Derivatives offsetting

The Company does not offset the fair value amounts of derivative instruments subject to master netting agreements in the Consolidated Condensed Balance Sheets.

Fair Value Disclosures [Abstract]

Fair value measurements

Fair value measurements

The Company measures certain assets and liabilities in accordance with ASC Topic 820, Fair Value Measurements and Disclosures, which defines fair value as the price that would be received for an asset or paid to transfer a liability in an orderly transaction between market participants on the measurement date. In addition, it establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three broad levels:

Level 1 - Quoted prices in active markets that are accessible at the measurement date for identical assets and liabilities. The fair value hierarchy gives the highest priority to level 1 inputs.

Level 2 - Observable inputs other than quoted prices in active markets.

Level 3 - Unobservable inputs for which there is little or no market data available. The fair value hierarchy gives the lowest priority to level 3 inputs.

Assets and liabilities measured at fair value on a recurring basis are as follows (in millions):

	May 31, 2018		Level 1		Level 2		Level 3
Assets:
Money market funds1	$	1,104	$	1,104	$	—	$	—

¹  Money market funds are valued at the closing price reported by the fund sponsor.

²  The fair value of quoted investments are based on current bid prices as of the balance sheet dates.

³  The fair value of forward currency contracts are estimated by discounting the difference between the contractual forward price and the current available forward price for the residual maturity of the contract using observable market rates.

⁴  The fair value of interest rate swaps is calculated by discounting the estimated future cash flows based on the applicable observable yield curves. See note 8, financial instruments for additional information.

There were no transfers between levels for the three and nine months ended May 31, 2018.

The Company reports its debt instruments under the guidance of ASC Topic 825, Financial Instruments, which requires disclosure of the fair value of the Company’s debt in the footnotes to the Consolidated Financial Statements. Unless otherwise noted, the fair value for all notes was determined based upon quoted market prices and therefore categorized as level 1. See note 7, debt for further information. The carrying values of accounts receivable, net and trade accounts payable approximated their respective fair values due to their short-term nature.

Commitments and Contingencies Disclosure [Abstract]

Commitments and contingencies

Commitments and contingencies

The Company is involved in legal proceedings and is subject to investigations, inspections, audits, inquiries and similar actions by governmental authorities, arising in the normal course of the Company’s business, including the matters described below. Legal proceedings, in general, and securities and class action litigation, in particular, can be expensive and disruptive. Some of these suits may purport or may be determined to be class actions and/or involve parties seeking large and/or indeterminate amounts, including punitive or exemplary damages, and may remain unresolved for several years. From time to time, the Company is also involved in legal proceedings as a plaintiff involving antitrust, tax, contract, intellectual property and other matters. Gain contingencies, if any, are recognized when they are realized. The results of legal proceedings are often uncertain and difficult to predict, and the costs incurred in litigation can be substantial, regardless of the outcome. The Company believes that its defenses and assertions in pending legal proceedings have merit, and does not believe that any of these pending matters, after consideration of applicable reserves and rights to indemnification, will have a material adverse effect on the Company’s consolidated financial position. However, substantial unanticipated verdicts, fines and rulings do sometimes occur. As a result, the Company could from time to time incur judgments, enter into settlements or revise its expectations regarding the outcome of certain matters, and such developments could have a material adverse effect on its results of operations in the period in which the amounts are accrued and/or its cash flows in the period in which the amounts are paid.

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 is 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.

On December 29, 2014, a putative shareholder filed a derivative action in federal court in the Northern District of Illinois against certain current and former directors and officers of Walgreen Co., and Walgreen Co. as a nominal defendant, arising out of certain public statements the Company made regarding its former fiscal 2016 goals. The action asserts claims for breach of fiduciary duty, waste and unjust enrichment. On April 10, 2015, the defendants filed a motion to dismiss. On May 18, 2015, the case was stayed in light of a securities class action that was filed on April 10, 2015. After a ruling issued on September 30, 2016 in the securities class action, which is described below, on November 3, 2016, the Court entered a stipulation and order extending the stay until the securities case is fully resolved.

On April 10, 2015, a putative shareholder filed a securities class action in federal court in the Northern District of Illinois against Walgreen Co. and certain former officers of Walgreen Co. The action asserts claims for violation of the federal securities laws arising out of certain public statements the Company made regarding its former fiscal 2016 goals. On June 16, 2015, the Court entered an order appointing a lead plaintiff. Pursuant to the Court’s order, lead plaintiff filed an amended complaint on August 17, 2015, and defendants moved to dismiss the amended complaint on October 16, 2015. Lead plaintiff filed a response to the motion to dismiss on December 22, 2015, and defendants filed a reply in support of the motion on February 5, 2016. On September 30, 2016, the Court issued an order granting in part and denying in part defendants’ motion to dismiss. Defendants filed their answer to the amended complaint on November 4, 2016 and filed an amended answer on January 16, 2017. Plaintiffs filed their motion for class certification on April 21, 2017. Plaintiffs’ motion was granted on March 29, 2018 and merits discovery is proceeding.

As of August 31, 2017, the Company was aware of two putative class action lawsuits filed by purported Rite Aid stockholders against Rite Aid and its board of directors, Walgreens Boots Alliance and Victoria Merger Sub, Inc. for claims arising out of the transactions contemplated by the original Merger Agreement (prior to its amendment on January 29, 2017) (such transactions, the “Rite Aid Transactions”). One Rite Aid action was filed in the State of Pennsylvania in the Court of Common Pleas of Cumberland County (the “Pennsylvania action”), and one action was filed in the United States District Court for the Middle District of Pennsylvania (the “federal action”). The Pennsylvania action primarily alleged that the Rite Aid board of directors breached its fiduciary duties in connection with the Rite Aid Transactions by, among other things, agreeing to an unfair and inadequate price, agreeing to deal protection devices that preclude other bidders from making successful competing offers for Rite Aid, and failing to disclose all allegedly material information concerning the proposed merger, and also alleged that Walgreens Boots Alliance and Victoria Merger Sub, Inc. aided and abetted these alleged breaches of fiduciary duty. The federal action alleged, among other things, that Rite Aid and its board of directors disseminated an allegedly false and misleading proxy statement in connection with the Rite Aid Transactions. The plaintiffs in the federal action also filed a motion for preliminary injunction seeking to enjoin the Rite Aid shareholder vote relating to the Rite Aid Transactions. That motion was denied and plaintiffs agreed to stay the litigation until after the Rite Aid Transactions closed. On March 17, 2017, plaintiffs moved to lift the stay to allow plaintiffs to file an amended complaint. On August 4, 2017, that motion was granted for the limited purpose of allowing plaintiffs to file a motion seeking leave to amend their complaint in light of the termination of the Merger Agreement. Plaintiffs filed such a motion on September 22, 2017. The Company filed its response on October 6, 2017. The Court granted the motion on November 27, 2017, ordering the plaintiffs to file their amended complaint within 10 business days. Plaintiffs filed their amended complaint on December 11, 2017. Pursuant to a briefing schedule set by the Court, the Company filed a motion to dismiss on February 16, 2018. Plaintiffs filed their response brief on May 1, 2018 and reply briefs were filed on June 7, 2018.

The Company was also named as a defendant in eight putative class action lawsuits filed in the Court of Chancery of the State of Delaware (the “Delaware actions”). Those actions were consolidated, and plaintiffs filed a motion for preliminary injunction seeking to enjoin the Rite Aid shareholder vote relating to the Rite Aid Transactions. That motion was denied and the plaintiffs in the Delaware actions agreed to settle this matter for an immaterial amount. The Delaware actions all have been dismissed.

In December 2017, the United States Judicial Panel on Multidistrict Litigation consolidated numerous cases filed against an array of defendants by various plaintiffs such as counties, cities, hospitals, Indian tribes and others, alleging claims generally concerning the impacts of widespread opioid abuse. The consolidated multidistrict litigation, captioned In re National Prescription Opiate Litigation (MDL No. 2804), is pending in the U.S. District Court for the Northern District of Ohio. The Company is named as a defendant in a subset of the cases included in this multidistrict litigation. The Company also has been named as a defendant in several lawsuits brought in state courts relating to opioid matters. The relief sought by various plaintiffs is compensatory and punitive damages, as well as injunctive relief. Additionally, the Company has received from the Attorney Generals of several states subpoenas, civil investigative demands, and/or other requests concerning opioid matters.

Income Tax Disclosure [Abstract]

Income taxes

Income taxes

The effective tax rate for the three and nine months ended May 31, 2018 was 7.6% and 19.4% respectively, compared to 12.4% and 16.2% for the three and nine months ended May 31, 2017. As further described below, the decrease in the effective tax rate for the three months ended and the increase in the effective tax rate for the nine months endedMay 31, 2018 were significantly impacted by an additional provisional net tax benefit of $140 million and a provisional net tax expense of $44 million respectively, as a result of the U.S. tax law changes, which were enacted on December 22, 2017. The decrease in the prior year comparable periods are due to higher net discrete tax benefits. In addition, the Company's results for the three and nine months ended May 31, 2018 also include a net reduction to the Company’s estimated annual tax rate for the current year as a result of the U.S. tax law changes.

Income taxes paid for the nine months endedMay 31, 2018 were $428 million, compared to $839 million for the nine months endedMay 31, 2017.

U.S. tax law changes

The United States government enacted comprehensive tax legislation in December 2017. The accounting guidance on income taxes generally requires the effects of new tax legislation to be recognized in the period of enactment. The SEC issued Staff Accounting Bulletin 118 (“SAB 118”), which provides for a measurement period of up to one year from the enactment date for companies to complete their accounting for the U.S. tax law changes. In accordance with the SEC staff guidance, companies must reflect the income tax effects of those aspects of the U.S. tax law changes for which the accounting is complete. To the extent a company’s accounting for the income tax effect of certain provisions of the U.S. tax law changes is incomplete but the Company is able to determine a reasonable estimate, a provisional estimate must be recorded in the Company’s financial statements. If companies cannot determine a provisional estimate for the effects of an aspect of the U.S. tax law changes, they should continue applying the accounting guidance on income taxes on the basis of the provisions of the tax laws in effect immediately before the U.S. tax law changes were enacted.

The U.S. tax law changes include broad and complex changes affecting the Company’s fiscal 2018 results. Among other things, the U.S. tax law changes reduce the federal corporate tax rate from 35% to 21% effective January 1, 2018 and require companies to immediately accrue for and pay over an eight year period a one-time transition tax on certain un-repatriated earnings of foreign subsidiaries. The U.S. tax law changes also alter the taxation of foreign earnings, repeal of the deduction for domestic production activities and establish a global intangible low tax income (GILTI) regime, as well as base erosion anti-avoidance tax (BEAT).

In connection with the Company’s ongoing analysis of the impact of the U.S. tax law changes, which is provisional and subject to change, the Company recorded a net tax expense of $44 million during the nine months ended May 31, 2018. This provisional net tax expense arises from the Company’s accrual for the transition tax and other U.S. tax law changes of $679 million, partly offset by a benefit of $635 million from re-measuring the Company’s net U.S. deferred tax liabilities.

Based on the effective dates of certain aspects of the U.S. tax law changes as well as estimated data required to be used in the corresponding measurement calculations, the Company’s analysis of the income tax effects of the U.S. tax law changes could not be finalized as of May 31, 2018. While the Company made reasonable estimates of the impact of the transition tax and the remeasurement of its deferred tax assets and liabilities, the final impact of the U.S. tax law changes may differ from these estimates, due to, among other things, changes in its interpretations and assumptions, additional guidance and actions the Company may take. The Company expects to finalize such provisional amounts within the time period prescribed by SAB 118. The U.S. tax law changes created new rules that allow the Company to make an accounting policy election to either treat taxes due on future GILTI inclusions in taxable income as either a current period expense or reflect such inclusions related to temporary basis differences in the Company’s measurement of deferred taxes. The Company’s analysis of the new GILTI rules is not complete; therefore, the Company has not made a policy election regarding the tax accounting treatment of the GILTI tax.

The U.S. tax law changes have the potential to change the Company’s assertions with respect to whether earnings of the Company’s foreign subsidiaries should remain indefinitely reinvested. The Company continues to evaluate these changes, therefore, the Company has not made any changes to its indefinite reinvestment assertions.

Retirement Benefits [Abstract]

Retirement benefits

Retirement benefits

The Company sponsors several retirement plans, including defined benefit plans, defined contribution plans and a postretirement health plan.

Defined benefit pension plans (non-U.S. plans)

The Company has various defined benefit pension plans outside the United States. The principal defined benefit pension plan is the Boots Pension Plan, which covers certain employees in the United Kingdom (the “Boots Plan”). The Boots Plan is a funded final salary defined benefit plan providing pensions and death benefits to members. The Boots Plan was closed to future accrual effective July 1, 2010, with pensions calculated based on salaries up until that date. The Boots Plan is governed by a trustee board, which is independent of the Company. The plan is subject to a full funding actuarial valuation on a triennial basis.

Components of net periodic pension costs for the defined benefit pension plans (in millions):

	Three months ended May 31,						Nine months ended May 31,
	2018			2017			2018			2017

Expected returns on plan assets/other	(54		)	(41		)	(158		)	(112		)
Total net periodic pension costs	$	(2	)	$	3		$	(7	)	$	20

The Company made cash contributions to its defined benefit pension plans of $57 million for the nine months ended May 31, 2018, which primarily related to committed funded payments. The Company plans to contribute an additional $7 million to its defined benefit pension plans in fiscal 2018.

Defined contribution plans

The principal retirement plan for U.S. employees is the Walgreen Profit-Sharing Retirement Trust, to which both the Company and participating employees contribute. The Company’s contribution is in the form of a guaranteed match which is approved annually by the Walgreen Co. Board of Directors and reviewed by the Compensation Committee and Finance Committee of the Walgreens Boots Alliance Board of Directors. The profit-sharing provision was an expense of $53 million and $164 million for the three and nine months ended May 31, 2018 compared to an expense of $58 million and $164 million in the three and nine months ended May 31, 2017.

The Company also has certain contract based defined contribution arrangements. The principal one is the Alliance Healthcare & Boots Retirement Savings Plan, which is United Kingdom based and to which both the Company and participating employees contribute. The cost recognized in the Consolidated Condensed Statements of Earnings for the three and nine months ended May 31, 2018 was $33 million and $94 million compared to a cost of $26 million and $82 million in the three and nine months ended May 31, 2017.

Postretirement healthcare plan

The Company provides certain health insurance benefits to retired U.S. employees who meet eligibility requirements, including age, years of service and date of hire. The costs of these benefits are accrued over the service life of the employee. An amendment to this plan in the third quarter of fiscal 2017 resulted in a $109 million curtailment gain.

Segment Reporting [Abstract]

Segment reporting

Segment reporting

The Company has aligned its operations into three reportable segments: Retail Pharmacy USA, Retail Pharmacy International, and Pharmaceutical Wholesale. The operating segments have been identified based on the financial data utilized by the Company’s Chief Executive Officer (the chief operating decision maker) to assess segment performance and allocate resources among the Company’s operating segments, which have been aggregated as described below. The chief operating decision maker uses adjusted operating income to assess segment profitability. The chief operating decision maker does not use total assets by segment to make decisions regarding resources, therefore the total asset disclosure by segment has not been included.

• The Retail Pharmacy USA segment consists of the Walgreens business, which includes the operation of retail drugstores and convenient care clinics; and operation of mail and central specialty pharmacy services. Sales for the segment are principally derived from the sale of prescription drugs and a wide assortment of retail products, including health and wellness, beauty, personal care and consumables and general merchandise.

• The Retail Pharmacy International segment consists of pharmacy-led health and beauty retail businesses and optical practices. These businesses include Boots branded stores in the United Kingdom, Thailand, Norway, the Republic of Ireland and the Netherlands; Benavides in Mexico and Ahumada in Chile. Sales for the segment are principally derived from the sale of prescription drugs and health and wellness, beauty, personal care and other consumer products.

• The Pharmaceutical Wholesale segment consists of the Alliance Healthcare pharmaceutical wholesaling and distribution businesses and an equity method investment in AmerisourceBergen. Wholesale operations are located in the United Kingdom, Germany, France, Turkey, Spain, the Netherlands, Egypt, Norway, Romania, Czech Republic and Lithuania. Sales for the segment are principally derived from wholesaling and distribution of a comprehensive offering of brand-name pharmaceuticals (including specialty pharmaceutical products) and generic pharmaceuticals, health and beauty products, home healthcare supplies and equipment, and related services to pharmacies and other healthcare providers.

The results of operations for each reportable segment include procurement benefits and an allocation of corporate-related overhead costs. The “Eliminations” column contains items not allocable to the reportable segments, as the information is not utilized by the chief operating decision maker to assess segment performance and allocate resources.

The following table reflects results of operations of the Company’s reportable segments (in millions):

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]

New accounting pronouncements

New accounting pronouncements

Adoption of new accounting pronouncements

Accounting for hedging activities

In August 2017, the FASB issued 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. The updated accounting policy for financial instruments is as follows:

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 - 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 Statements of Earnings when the hedged item affects earnings. When a derivative in a hedge relationship is terminated or the hedged item is sold, extinguished or terminated, hedge accounting is discontinued prospectively.

New accounting pronouncements not yet adopted

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 is evaluating the effect of adopting this new accounting guidance. 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.

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 minus impairment, if any, plus or minus 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 continues to evaluate the impact of this ASU, the related amendments and the interpretive guidance on the Company's consolidated financial statements, and will use the modified retrospective method as the transition approach when adopting this new accounting guidance on September 1, 2018 (fiscal 2019). Based on the preliminary assessment, the impact of adopting the new guidance will not be material to the consolidated financial statements and will be limited to immaterial changes to the timing of 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.

Basis of Presentation

Basis of presentation

The Consolidated Condensed Financial Statements of Walgreens Boots Alliance, Inc. (“Walgreens Boots Alliance” or the “Company”) included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission regarding interim financial reporting. The Consolidated Condensed Financial Statements include all subsidiaries in which the Company holds a controlling interest. Investments in less than majority-owned subsidiaries in which the Company does not have a controlling interest, but does have significant influence, are accounted for as equity method investments. All intercompany transactions have been eliminated.

The Consolidated Condensed Financial Statements included herein are unaudited. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) have been condensed or omitted pursuant to such rules and regulations, although the Company believes that the disclosures are adequate to make the information presented not misleading. These unaudited Consolidated Condensed Financial Statements should be read in conjunction with the audited financial statements and the notes thereto included in the Walgreens Boots Alliance Annual Report on Form 10-K for the fiscal year ended August 31, 2017.

In the opinion of management, the unaudited Consolidated Condensed Financial Statements for the interim periods presented include all adjustments (consisting only of normal recurring adjustments) necessary to present a fair statement of the results for such interim periods. 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. With respect to the Company’s Retail Pharmacy USA segment, the positive impact on gross profit margins and gross profit dollars typically has been significant in the first several months after a generic version of a drug is first allowed to compete with the branded version, which is generally referred to as a “generic conversion”. In any given year, the number of major brand name drugs that undergo a conversion from branded to generic status can increase or decrease, which can have a significant impact on the Company’s Retail Pharmacy USA segment’s sales, gross profit margins and gross profit dollars making the Company’s operations or net earnings for any period incomparable.
