Summary of Significant Accounting Policies

Basis of presentation

Accounting Policies

Basis of Presentation

The Condensed Consolidated Financial Statements of Wal-Mart Stores, Inc. and its subsidiaries ("Walmart" or the "Company") and the accompanying notes included in this Quarterly Report on Form 10-Q are unaudited. In the opinion of management, all adjustments necessary for the fair presentation of the Condensed Consolidated Financial Statements have been included. Such adjustments are of a normal, recurring nature. The Condensed Consolidated Financial Statements, and the accompanying notes, are prepared in accordance with generally accepted accounting principles in the United States ("GAAP") and do not contain certain information included in the Company's Annual Report on Form 10-K for the fiscal year ended January 31, 2017 ("fiscal 2017"). Therefore, the interim Condensed Consolidated Financial Statements should be read in conjunction with that Annual Report on Form 10-K.

The Company's Condensed Consolidated Financial Statements are based on a fiscal year ending January 31 for the United States ("U.S.") and Canadian operations. The Company consolidates all other operations generally using a one-month lag and based on a calendar year. There were no intervening events during the month of October 2017 related to the operations consolidated using a lag that materially affected the Condensed Consolidated Financial Statements.

The Company's business is seasonal to a certain extent due to calendar events and national and religious holidays, as well as weather patterns. Historically, the Company's highest sales volume and operating income have occurred in the fiscal quarter ending January 31.

Receivables

Receivables are stated at their carrying values, net of a reserve for doubtful accounts. Receivables consist primarily of amounts due from:


•	insurance companies resulting from pharmacy sales;


•	banks for customer credit and debit cards and electronic bank transfers that take in excess of seven days to process;


•	consumer financing programs in certain international operations;


•	suppliers for marketing or incentive programs; and


•	real estate transactions.

The Walmart International segment offers a limited number of consumer credit products, primarily through its financial institutions in Canada and Chile to customers in those markets. The receivable balance from consumer credit products was $1.3 billion, net of a reserve for doubtful accounts of $83 million at October 31, 2017, compared to a receivable balance of $1.2 billion, net of a reserve for doubtful accounts of $79 million at January 31, 2017.

Inventories

The Company values inventories at the lower of cost or market as determined primarily by the retail inventory method of accounting, using the last-in, first-out ("LIFO") method for substantially all of the Walmart U.S. segment's inventories. The inventory at the Walmart International segment is valued primarily by the retail inventory method of accounting, using the first-in, first-out ("FIFO") method. The retail inventory method of accounting results in inventory being valued at the lower of cost or market, since permanent markdowns are immediately recorded as a reduction of the retail value of inventory. The inventory at the Sam's Club segment is valued using the LIFO method. At October 31, 2017 and January 31, 2017, the Company's inventories valued at LIFO approximated those inventories as if they were valued at FIFO.

Recent Accounting Pronouncements

Revenue Recognition

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers (Topic 606). This ASU represents a single comprehensive model to recognize revenue to depict the transfer of promised goods or services to a customer at an amount that reflects the consideration it expects to be entitled to in exchange for those goods or services. Management has substantially completed its evaluation of existing contracts and the impact to the Company's consolidated net income, balance sheet and cash flows. The Company will adopt this ASU on February 1, 2018, under the modified retrospective approach, which will result in an immaterial cumulative adjustment to retained earnings. The ASU will also require additional disclosures.

Leases

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which requires lease assets and liabilities to be recorded on the balance sheet. Certain qualitative and quantitative disclosures are also required, as well as retrospective recognition and measurement of impacted leases. The Company will adopt this ASU on February 1, 2019 and is implementing new lease systems in connection with the adoption. Management is still evaluating the effect to the Company's consolidated net income, balance sheet, cash flows and disclosures. Management expects a material impact to the consolidated balance sheet.

Financial Instruments

In January 2016, the FASB issued ASU 2016-01, Financial Instruments–Overall (Topic 825), which updates certain aspects of recognition, measurement, presentation and disclosure of financial instruments. The Company will adopt this ASU on February 1, 2018. This ASU will primarily impact the Company's accounting for its investment in JD.com ("JD"). Upon adoption, the Company will record a cumulative effect adjustment to retained earnings, which could be material depending on the market value of our investment in JD at January 31, 2018. Subsequent to adoption, changes in the value of the Company's investment in JD will be recorded in consolidated net income.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments–Credit Losses (Topic 326), which modifies the measurement of expected credit losses of certain financial instruments. The Company will adopt this ASU on February 1, 2020. Management is currently evaluating this ASU to determine its impact to the Company's consolidated net income, balance sheet, cash flows and disclosures.

In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging–Targeted Improvements to Accounting for Hedging Activities (Topic 815), which amends and simplifies hedge accounting with the intent of better aligning financial reporting with an entity's risk management activities. The ASU is effective February 1, 2019. Management is currently evaluating this ASU to determine when the Company will adopt it and the resulting impact to the Company's consolidated financial statements.

Stock Compensation

In March 2016, the FASB issued ASU 2016-09, Compensation–Stock Compensation (Topic 718), which is intended to simplify accounting for share-based payment transactions. The ASU changed several aspects of the accounting for share-based payment award transactions, including accounting for income taxes, forfeitures and minimum statutory tax withholding requirements. Management adopted this ASU beginning February 1, 2017, and as a result, reclassified an immaterial amount from operating activities to financing activities in the Company's prior year consolidated cash flows.

Net Income Per Common Share

Net income per common share

Net Income Per Common Share

Basic net income per common share attributable to Walmart is based on the weighted-average common shares outstanding during the relevant period. Diluted net income per common share attributable to Walmart is based on the weighted-average common shares outstanding during the relevant period adjusted for the dilutive effect of share-based awards. The Company did not have significant share-based awards outstanding that were antidilutive and not included in the calculation of diluted net income per common share attributable to Walmart for the three and nine months ended October 31, 2017 and 2016.

The following table provides a reconciliation of the numerators and denominators used to determine basic and diluted net income per common share attributable to Walmart:

In connection with extinguishing debt, the Company paid premiums of approximately $2.1 billion during the nine months ended October 31, 2017, resulting in a loss on extinguishment of debt of approximately $2.1 billion.

The Company also repaid other, smaller long-term debt as it matured in non-U.S. markets.

Fair Value Measurements

Fair value measurements

Fair Value Measurements

The Company records and discloses certain financial and non-financial assets and liabilities at fair value. The fair value of an asset is the price at which the asset could be sold in an ordinary transaction between unrelated, knowledgeable and willing parties able to engage in the transaction. The fair value of a liability is the amount that would be paid to transfer the liability to a new obligor in a transaction between such parties, not the amount that would be paid to settle the liability with the creditor. Assets and liabilities recorded at fair value are measured using the fair value hierarchy, which prioritizes the inputs used in measuring fair value. The levels of the fair value hierarchy are:


•	Level 1: observable inputs such as quoted prices in active markets;


•	Level 2: inputs other than quoted prices in active markets that are either directly or indirectly observable; and


•	Level 3: unobservable inputs for which little or no market data exists, therefore requiring the Company to develop its own assumptions.

Recurring Fair Value Measurements

The Company holds derivative instruments that are required to be measured at fair value on a recurring basis. The fair values are the estimated amounts the Company would receive or pay upon termination of the related derivative agreements as of the reporting dates. The fair values have been measured using the income approach and Level 2 inputs, which include the relevant interest rate and foreign currency forward curves. As of October 31, 2017 and January 31, 2017, the notional amounts and fair values of these derivatives were as follows:



	October 31, 2017					January 31, 2017
(Amounts in millions)	Notional Amount		Fair Value			Notional Amount		Fair Value
Receive fixed-rate, pay variable-rate interest rate swaps designated as fair value hedges	$	5,000	$	(6	)	$	5,000	$	(4	)
Receive fixed-rate, pay fixed-rate cross-currency swaps designated as net investment hedges	2,250		399			2,250		471
Receive fixed-rate, pay fixed-rate cross-currency swaps designated as cash flow hedges	4,240		(254		)	3,957		(618		)
Total	$	11,490	$	139		$	11,207	$	(151	)

Additionally, the Company's available-for-sale securities are measured at fair value on a recurring basis using Level 1 inputs. Changes in fair value are recorded in accumulated other comprehensive loss. The cost basis and fair value of the Company's available-for-sale securities as of October 31, 2017 and January 31, 2017, are as follows:



	October 31, 2017				January 31, 2017
(Amounts in millions)	Cost Basis		Fair Value		Cost Basis		Fair Value
Available-for-sale securities	$	1,901	$	2,703	$	1,901	$	2,046

Nonrecurring Fair Value Measurements

In addition to assets and liabilities that are recorded at fair value on a recurring basis, the Company's assets and liabilities are also subject to nonrecurring fair value measurements. Generally, assets are recorded at fair value on a nonrecurring basis as a result of impairment charges. The Company did not record any significant impairment charges to assets measured at fair value on a nonrecurring basis during the three and nine months ended October 31, 2017 or for the fiscal year ended January 31, 2017.

Other Fair Value Disclosures

The Company records cash and cash equivalents and short-term borrowings at cost. The carrying values of these instruments approximate their fair value due to their short-term maturities.

The Company's long-term debt is also recorded at cost. The fair value is estimated using Level 2 inputs based on the Company's current incremental borrowing rate for similar types of borrowing arrangements. The carrying value and fair value of the Company's long-term debt as of October 31, 2017 and January 31, 2017, are as follows:



	October 31, 2017				January 31, 2017
(Amounts in millions)	Carrying Value		Fair Value		Carrying Value		Fair Value
Long-term debt, including amounts due within one year	$	37,463	$	43,378	$	38,271	$	44,602

Derivative Financial Instruments

Derivative financial instruments

Derivative Financial Instruments

The Company uses derivative financial instruments for hedging and non-trading purposes to manage its exposure to changes in interest and currency exchange rates, as well as to maintain an appropriate mix of fixed- and variable-rate debt. Use of derivative financial instruments in hedging programs subjects the Company to certain risks, such as market and credit risks. Market risk represents the possibility that the value of the derivative financial instrument will change. In a hedging relationship, the change in the value of the derivative financial instrument is offset to a great extent by the change in the value of the underlying hedged item. Credit risk related to a derivative financial instrument represents the possibility that the counterparty will not fulfill the terms of the contract. The notional, or contractual, amount of the Company's derivative financial instruments is used to measure interest to be paid or received and does not represent the Company's exposure due to credit risk. Credit risk is monitored through established approval procedures, including setting concentration limits by counterparty, reviewing credit ratings and requiring collateral (generally cash) from the counterparty when appropriate.

The Company only enters into derivative transactions with counterparties rated "A-" or better by nationally recognized credit rating agencies. Subsequent to entering into derivative transactions, the Company regularly monitors the credit ratings of its counterparties. In connection with various derivative agreements, including master netting arrangements, the Company held cash collateral from counterparties of $251 million and $242 million at October 31, 2017 and January 31, 2017, respectively. The Company records cash collateral received as amounts due to the counterparties exclusive of any derivative asset. Furthermore, as part of the master netting arrangements with each of these counterparties, the Company is also required to post collateral with a counterparty if the Company's net derivative liability position exceeds $150 million with such counterparties. The Company did not have any cash collateral posted with counterparties at October 31, 2017 and January 31, 2017, respectively. The Company records cash collateral it posts with counterparties as amounts receivable from those counterparties exclusive of any derivative liability.

The Company uses derivative financial instruments for the purpose of hedging its exposure to interest and currency exchange rate risks and, accordingly, the contractual terms of a hedged instrument closely mirror those of the hedged item, providing a high degree of risk reduction and correlation. Contracts that are effective at meeting the risk reduction and correlation criteria are recorded using hedge accounting. If a derivative financial instrument is recorded using hedge accounting, depending on the nature of the hedge, changes in the fair value of the instrument will either be offset against the change in fair value of the hedged assets, liabilities or firm commitments through earnings or be recognized in accumulated other comprehensive loss until the hedged item is recognized in earnings. Any hedge ineffectiveness is immediately recognized in earnings. The Company's net investment and cash flow instruments are highly effective hedges and the ineffective portion has not been, and is not expected to be, significant. Instruments that do not meet the criteria for hedge accounting, or contracts for which the Company has not elected hedge accounting, are recorded at fair value with unrealized gains or losses reported in earnings during the period of the change.

Fair Value Instruments

The Company is a party to receive fixed-rate, pay variable-rate interest rate swaps that the Company uses to hedge the fair value of fixed-rate debt. The notional amounts are used to measure interest to be paid or received and do not represent the Company's exposure due to credit loss. The Company's interest rate swaps that receive fixed-interest rate payments and pay variable-interest rate payments are designated as fair value hedges. As the specific terms and notional amounts of the derivative instruments match those of the fixed-rate debt being hedged, the derivative instruments are assumed to be perfectly effective hedges. Changes in the fair values of these derivative instruments are recorded in earnings, but are offset by corresponding changes in the fair values of the hedged items, also recorded in earnings, and, accordingly, do not impact the Company's Condensed Consolidated Statements of Income. These fair value instruments will mature on dates ranging from October 2020 to April 2024.

Net Investment Instruments

The Company is a party to cross-currency interest rate swaps that the Company uses to hedge its net investments. The agreements are contracts to exchange fixed-rate payments in one currency for fixed-rate payments in another currency. All changes in the fair value of these instruments are recorded in accumulated other comprehensive loss, offsetting the currency translation adjustment of the related investment that is also recorded in accumulated other comprehensive loss. These instruments will mature on dates ranging from July 2020 to February 2030.

The Company has issued foreign-currency-denominated long-term debt as hedges of net investments of certain of its foreign operations. These foreign-currency-denominated long-term debt issuances are designated and qualify as nonderivative hedging instruments. Accordingly, the foreign currency translation of these debt instruments is recorded in accumulated other comprehensive loss, offsetting the foreign currency translation adjustment of the related net investments that is also recorded in accumulated other comprehensive loss. At October 31, 2017 and January 31, 2017, the Company had ¥180 billion and ¥10 billion, respectively, of outstanding long-term debt designated as a hedge of its net investment in Japan, as well as outstanding long-term debt of £2.1 billion and £2.5 billion at October 31, 2017 and January 31, 2017, respectively, that was designated as a hedge of its net investment in the United Kingdom. These nonderivative net investment hedges will mature on dates ranging from July 2020 to January 2039.

Cash Flow Instruments

The Company is a party to receive fixed-rate, pay fixed-rate cross-currency interest rate swaps to hedge the currency exposure associated with the forecasted payments of principal and interest of certain non-U.S. denominated debt. The swaps are designated as cash flow hedges of the currency risk related to payments on the non-U.S. denominated debt. The effective portion of changes in the fair value of derivatives designated as cash flow hedges of foreign exchange risk is recorded in accumulated other comprehensive loss and is subsequently reclassified into earnings in the period that the hedged forecasted transaction affects earnings. The hedged items are recognized foreign currency-denominated liabilities that are re-measured at spot exchange rates each period, and the assessment of effectiveness (and measurement of any ineffectiveness) is based on total changes in the related derivative's cash flows. As a result, the amount reclassified into earnings each period includes an amount that offsets the related transaction gain or loss arising from that re-measurement and the adjustment to earnings for the period's allocable portion of the initial spot-forward difference associated with the hedging instrument. These cash flow instruments will mature on dates ranging from April 2022 to March 2034.

Financial Statement Presentation

Although subject to master netting arrangements, the Company does not offset derivative assets and derivative liabilities in its Condensed Consolidated Balance Sheets. Derivative instruments with an unrealized gain are recorded in the Company's Condensed Consolidated Balance Sheets as either current or non-current assets, based on maturity date, and those hedging instruments with an unrealized loss are recorded as either current or non-current liabilities, based on maturity date. Refer to Note 5 for the net presentation of the Company's derivative instruments.

The Company's derivative instruments, as well as its nonderivative debt instruments designated and qualifying as net investment hedges, were classified as follows in the Company's Condensed Consolidated Balance Sheets:



	October 31, 2017						January 31, 2017
(Amounts in millions)	Fair Value Instruments		Net Investment Instruments		Cash Flow Instruments		Fair Value Instruments		Net Investment Instruments		Cash Flow Instruments
Derivative instruments
Derivative assets:
Other assets and deferred charges	$	7	$	399	$	86	$	8	$	471	$	—

Derivative liabilities:
Deferred income taxes and other	13		—		340		12		—		618

Nonderivative hedging instruments
Long-term debt	—		4,423		—		—		3,209		—

Gains and losses related to the Company's derivatives primarily relate to interest rate hedges, which are recorded in interest, net, in the Company's Condensed Consolidated Statements of Income. Amounts related to the Company's derivatives expected to be reclassified from accumulated other comprehensive loss to net income during the next 12 months are not significant.

Share Repurchases

Share repurchases

Share Repurchases

From time to time, the Company repurchases shares of its common stock under share repurchase programs authorized by the Company's Board of Directors. All repurchases made during the nine months ended October 31, 2017 were made under the plan in effect at the beginning of the fiscal year. On October 9, 2017, the Board of Directors approved a new $20.0 billion share repurchase program which, beginning on November 20, 2017, replaced the previous share repurchase program. As of October 31, 2017, authorization for $2.6 billion of share repurchases remained under the share repurchase program that was in effect at the beginning of the quarter and that expired on November 17, 2017. Any repurchased shares are constructively retired and returned to an unissued status.

The Company considers several factors in determining when to execute share repurchases, including, among other things, current cash needs, capacity for leverage, cost of borrowings and the market price of its common stock. The following table provides, on a settlement date basis, the number of shares repurchased, average price paid per share and total amount paid for share repurchases for the nine months ended October 31, 2017 and 2016:



	Nine Months Ended October 31,
(Amounts in millions, except per share data)	2017		2016
Total number of shares repurchased	87.8		90.6
Average price paid per share	$	75.76	$	69.04
Total amount paid for share repurchases	$	6,656	$	6,254

The dividend installments payable on April 3, 2017, June 5, 2017 and September 5, 2017 were paid as scheduled.

Contingencies

Legal Proceedings

The Company is involved in a number of legal proceedings. The Company has made accruals with respect to these matters, where appropriate, which are reflected in the Company's Condensed Consolidated Financial Statements. For some matters, a liability is not probable or the amount cannot be reasonably estimated and therefore an accrual has not been made. However, where a liability is reasonably possible and may be material, such matters have been disclosed. The Company may enter into discussions regarding settlement of these matters, and may enter into settlement agreements, if it believes settlement is in the best interest of the Company and its shareholders.

Unless stated otherwise, the matters discussed below, if decided adversely to or settled by the Company, individually or in the aggregate, may result in a liability material to the Company's financial condition or results of operations.

ASDA Equal Value Claims

ASDA Stores, Ltd. ("ASDA"), a wholly-owned subsidiary of the Company, is a defendant in over 10,000 "equal value" claims that are proceeding before an Employment Tribunal in Manchester (the "Employment Tribunal") in the United Kingdom ("UK") on behalf of current and former ASDA store employees, and further claims may be asserted in the future. The claimants allege that the work performed by female employees in ASDA's retail stores is of equal value in terms of, among other things, the demands of their jobs compared to that of male employees working in ASDA's warehouse and distribution facilities, and that the disparity in pay between these different job positions is not objectively justified. As a result, claimants are requesting differential back pay based on higher wage rates in the warehouse and distribution facilities and higher wage rates on a prospective basis.

On March 23, 2015, ASDA asked the Employment Tribunal to stay all proceedings and to "strike out" substantially all of the claims because the claimants had not adhered to the Tribunal’s procedural rule for including multiple claimants on a the same claim form. On July 23, 2015, the Employment Tribunal denied ASDA's requests. Following additional proceedings, on June 20, 2017, the Employment Appeal Tribunal ruled in favor of ASDA on the "strike out" issue and remitted the matter to the Employment Tribunal to determine whether the improperly filed claims should be struck out. On July 12, 2017, claimants sought permission from the Court of Appeals to appeal this ruling, which was granted on October 3, 2017.

As to the initial phase of the Equal Value claims, on October 14, 2016, following a preliminary hearing, the Employment Tribunal ruled that claimants could compare their positions in ASDA's retail stores with those of employees in ASDA's warehouse and distribution facilities. On August 31, 2017, the Employment Appeal Tribunal affirmed the Employment Tribunal's ruling. The Employment Appeal Tribunal also granted permission for ASDA to appeal substantially all of its findings on August 31, 2017. ASDA sought permission to appeal the remainder of the Employment Appeal Tribunal's findings to the Court of Appeals on September 21, 2017.

Claimants are now proceeding in the next phase of their claims. That phase will determine whether the work performed by the claimants is of equal value to the work performed by employees in ASDA's warehouse and distribution facilities.

At present, the Company cannot predict the number of such claims that may be filed, and cannot reasonably estimate any loss or range of loss that may arise from these proceedings. The Company believes it has substantial factual and legal defenses to these claims, and intends to defend the claims vigorously.

FCPA Investigation and Related Matters

The Audit Committee (the "Audit Committee") of the Board of Directors of the Company has been conducting an internal investigation into, among other things, alleged violations of the U.S. Foreign Corrupt Practices Act ("FCPA") and other alleged crimes or misconduct in connection with foreign subsidiaries, including Wal-Mart de México, S.A.B. de C.V. ("Walmex"), and whether prior allegations of such violations and/or misconduct were appropriately handled by the Company. The Audit Committee and the Company have engaged outside counsel from a number of law firms and other advisors who are assisting in the on-going investigation of these matters.

The Company has also been conducting a voluntary global review of its policies, practices and internal controls for anti-corruption compliance. The Company is engaged in strengthening its global anti-corruption compliance program through appropriate remedial anti-corruption measures. In November 2011, the Company voluntarily disclosed that investigative activity to the U.S. Department of Justice (the "DOJ") and the Securities and Exchange Commission (the "SEC"). Since the implementation of the global review and the enhanced anti-corruption compliance program, the Audit Committee and the Company have identified or been made aware of additional allegations regarding potential violations of the FCPA. When such allegations have been reported or identified, the Audit Committee and the Company, together with their third party advisors, have conducted inquiries and when warranted based on those inquiries, opened investigations. Inquiries or investigations regarding allegations of potential FCPA violations were commenced in a number of foreign markets where the Company operates, including, but not limited to, Brazil, China and India.

As previously disclosed, the Company is under investigation by the DOJ and the SEC regarding possible violations of the FCPA. The Company has been cooperating with the agencies and discussions have been ongoing regarding the resolution of these matters. These discussions have progressed to a point that the Company can now reasonably estimate a probable loss and has recorded an aggregate accrual of $283 million with respect to these matters (the "Accrual"). As the discussions are continuing, there can be no assurance as to the timing or the terms of the final resolution of these matters.

A number of federal and local government agencies in Mexico have also initiated investigations of these matters. Walmex is cooperating with the Mexican governmental agencies conducting these investigations. Furthermore, lawsuits relating to the matters under investigation have been filed by several of the Company's shareholders against it, certain of its current directors, and certain of its former directors, certain of its former officers and certain of Walmex's former officers.

The Company could be exposed to a variety of negative consequences as a result of the matters noted above. There could be one or more enforcement actions in respect of the matters that are the subject of some or all of the on-going government investigations, and such actions, if brought, may result in judgments, settlements, fines, penalties, injunctions, cease and desist orders, debarment or other relief, criminal convictions and/or penalties and the shareholder lawsuits referenced above may result in judgments against the Company and its current and former directors and officers named in those proceedings. The Company expects that there will be on-going media and governmental interest, including additional news articles from media publications on these matters, which could impact the perception among certain audiences of the Company's role as a corporate citizen.

In addition, the Company has incurred and expects to continue to incur costs in responding to requests for information or subpoenas seeking documents, testimony and other information in connection with the government investigations, in defending the shareholder lawsuits, and in conducting the review and investigations. These costs will be expensed as incurred. For the three and nine months ended October 31, 2017 and 2016, the Company incurred the following third-party expenses in connection with the FCPA investigation and related matters:



	Three Months Ended October 31,				Nine Months Ended October 31,
(Amounts in millions)	2017		2016		2017		2016
Ongoing inquiries and investigations	$	2	$	24	$	22	$	68
Global compliance program and organizational enhancements	3		5		11		14
Total	$	5	$	29	$	33	$	82

The Company does not presently believe that these matters, including the Accrual (and the payment of the Accrual at some point-in-time in the future), will have a material adverse effect on its business, although given the inherent uncertainties in such situations, the Company can provide no assurance that these matters will not be material to its business in the future.

Acquisitions, Disposals and Related Items

Acquisitions, disposals and related items

Acquisitions, Disposals and Related Items

The Company completed certain eCommerce acquisitions during the three and nine months ended October 31, 2017, which were immaterial, individually and in the aggregate, to the Company's Condensed Consolidated Financial Statements.

The following significant transaction primarily impacts the operations of the Company's Walmart U.S. segment:

Jet.com, Inc. ("jet.com")

In September 2016, the Company completed the acquisition of jet.com, a U.S.-based eCommerce company. The integration of jet.com into the Walmart U.S. segment is building upon the current eCommerce foundation, allowing for synergies from talent, logistical operations and access to a broader customer base. The total purchase price for the acquisition was $2.4 billion, net of cash acquired. The allocation of the purchase price includes $1.7 billion in goodwill and $0.6 billion in intangible assets. As part of the transaction, the Company will pay additional compensation of approximately $0.8 billion over a five-year period.

The following significant transactions impact the operations of the Company's Walmart International segment:

Suburbia

In April 2017, one of the Company's subsidiaries sold Suburbia, the apparel retail division in Mexico, for $1.0 billion. As part of the sales agreement, the Company is also leasing certain real estate to the purchaser. The sale resulted in a pre-tax gain of $0.7 billion, of which $0.4 billion was recognized in the second quarter of fiscal 2018 in membership and other income, and the remainder was deferred and is being recognized over the lease terms of approximately 20 years.

Yihaodian and JD

In June 2016, the Company sold certain assets relating to Yihaodian, its eCommerce operations in China, including the Yihaodian brand, website and application, to JD in exchange for Class A ordinary shares of JD representing approximately five percent of JD's outstanding ordinary shares on a fully diluted basis. The $1.5 billion investment in JD is carried at cost and is included in other assets and deferred charges in the accompanying Consolidated Balance Sheets. The sale resulted in the recognition of a $535 million noncash gain, which was included in membership and other income. Subsequently, during fiscal 2017, the Company purchased $1.9 billion of additional JD shares classified as available for sale securities, representing an incremental ownership percentage of approximately five percent, for a total ownership of approximately ten percent of JD's outstanding ordinary shares.

Segments

The Company is engaged in retail and wholesale operations located in the U.S., Argentina, Brazil, Canada, Chile, China, India, Japan, Mexico and the United Kingdom, as well as countries located in Africa and Central America. The Company's operations are conducted in three business segments: Walmart U.S., Walmart International and Sam's Club. The Company defines its segments as those operations whose results its chief operating decision maker ("CODM") regularly reviews to analyze performance and allocate resources. The Company sells similar individual products and services in each of its segments. It is impractical to segregate and identify revenues for each of these individual products and services.

The Walmart U.S. segment includes the Company's mass merchant concept in the U.S. operating under the "Walmart" or "Wal-Mart" brands, as well as digital retail. The Walmart International segment consists of the Company's operations outside of the U.S., including various retail websites. The Sam's Club segment includes the warehouse membership clubs in the U.S., as well as digital retail. Corporate and support consists of corporate overhead and other items not allocated to any of the Company's segments.

The Company measures the results of its segments using, among other measures, each segment's net sales and operating income, which includes certain corporate overhead allocations. From time to time, the Company revises the measurement of each segment's operating income, including any corporate overhead allocations, as determined by the information regularly reviewed by its CODM. When the measurement of a segment changes, previous period amounts and balances are reclassified to be comparable to the current period's presentation.

Net sales by segment are as follows:



	Three Months Ended October 31,				Nine Months Ended October 31,
(Amounts in millions)	2017		2016		2017		2016
Net sales:
Walmart U.S.	$	77,724	$	74,550	$	231,898	$	224,086
Walmart International	29,548		28,390		84,976		85,094
Sam's Club	14,864		14,236		43,737		42,387
Net sales	$	122,136	$	117,176	$	360,611	$	351,567

Operating income by segment, as well as operating loss for corporate and support, interest, net, and loss on extinguishment of debt are as follows:



	Three Months Ended October 31,						Nine Months Ended October 31,
(Amounts in millions)	2017			2016			2017			2016
Operating income (loss):

Accounting Policies Summary of Significant Accounting Policies (Policies)

Receivables, policy

Receivables

Receivables are stated at their carrying values, net of a reserve for doubtful accounts. Receivables consist primarily of amounts due from:


•	insurance companies resulting from pharmacy sales;


•	banks for customer credit and debit cards and electronic bank transfers that take in excess of seven days to process;


•	consumer financing programs in certain international operations;


•	suppliers for marketing or incentive programs; and


•	real estate transactions.

The Walmart International segment offers a limited number of consumer credit products, primarily through its financial institutions in Canada and Chile to customers in those markets. The receivable balance from consumer credit products was $1.3 billion, net of a reserve for doubtful accounts of $83 million at October 31, 2017, compared to a receivable balance of $1.2 billion, net of a reserve for doubtful accounts of $79 million at January 31, 2017.

Inventory, policy

Inventories

The Company values inventories at the lower of cost or market as determined primarily by the retail inventory method of accounting, using the last-in, first-out ("LIFO") method for substantially all of the Walmart U.S. segment's inventories. The inventory at the Walmart International segment is valued primarily by the retail inventory method of accounting, using the first-in, first-out ("FIFO") method. The retail inventory method of accounting results in inventory being valued at the lower of cost or market, since permanent markdowns are immediately recorded as a reduction of the retail value of inventory. The inventory at the Sam's Club segment is valued using the LIFO method. At October 31, 2017 and January 31, 2017, the Company's inventories valued at LIFO approximated those inventories as if they were valued at FIFO.

New accounting pronouncements, policy

Recent Accounting Pronouncements

Revenue Recognition

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers (Topic 606). This ASU represents a single comprehensive model to recognize revenue to depict the transfer of promised goods or services to a customer at an amount that reflects the consideration it expects to be entitled to in exchange for those goods or services. Management has substantially completed its evaluation of existing contracts and the impact to the Company's consolidated net income, balance sheet and cash flows. The Company will adopt this ASU on February 1, 2018, under the modified retrospective approach, which will result in an immaterial cumulative adjustment to retained earnings. The ASU will also require additional disclosures.

Leases

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which requires lease assets and liabilities to be recorded on the balance sheet. Certain qualitative and quantitative disclosures are also required, as well as retrospective recognition and measurement of impacted leases. The Company will adopt this ASU on February 1, 2019 and is implementing new lease systems in connection with the adoption. Management is still evaluating the effect to the Company's consolidated net income, balance sheet, cash flows and disclosures. Management expects a material impact to the consolidated balance sheet.

Financial Instruments

In January 2016, the FASB issued ASU 2016-01, Financial Instruments–Overall (Topic 825), which updates certain aspects of recognition, measurement, presentation and disclosure of financial instruments. The Company will adopt this ASU on February 1, 2018. This ASU will primarily impact the Company's accounting for its investment in JD.com ("JD"). Upon adoption, the Company will record a cumulative effect adjustment to retained earnings, which could be material depending on the market value of our investment in JD at January 31, 2018. Subsequent to adoption, changes in the value of the Company's investment in JD will be recorded in consolidated net income.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments–Credit Losses (Topic 326), which modifies the measurement of expected credit losses of certain financial instruments. The Company will adopt this ASU on February 1, 2020. Management is currently evaluating this ASU to determine its impact to the Company's consolidated net income, balance sheet, cash flows and disclosures.

In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging–Targeted Improvements to Accounting for Hedging Activities (Topic 815), which amends and simplifies hedge accounting with the intent of better aligning financial reporting with an entity's risk management activities. The ASU is effective February 1, 2019. Management is currently evaluating this ASU to determine when the Company will adopt it and the resulting impact to the Company's consolidated financial statements.

Stock Compensation

In March 2016, the FASB issued ASU 2016-09, Compensation–Stock Compensation (Topic 718), which is intended to simplify accounting for share-based payment transactions. The ASU changed several aspects of the accounting for share-based payment award transactions, including accounting for income taxes, forfeitures and minimum statutory tax withholding requirements. Management adopted this ASU beginning February 1, 2017, and as a result, reclassified an immaterial amount from operating activities to financing activities in the Company's prior year consolidated cash flows.
