| Summary of Significant Accounting Policies | NOTE 1 : Summary of Significant Accounting Policies Lowe’s Companies, Inc. and subsidiaries (the Company) is the world’s second-largest home improvement retailer and operated 2,152 stores in the United States, Canada, and Mexico at February 2, 2018 . Below are those accounting policies considered by the Company to be significant. Fiscal Year - The Company’s fiscal year ends on the Friday nearest the end of January. Fiscal years 2017 and 2015 each contained 52 weeks and fiscal 2016 contained 53 weeks. All references herein for the years 2017 , 2016 , and 2015 represent the fiscal years ended February 2, 2018 , February 3, 2017 , and January 29, 2016 , respectively. Principles of Consolidation - The consolidated financial statements include the accounts of the Company and its wholly-owned or controlled operating subsidiaries. All intercompany accounts and transactions have been eliminated. Foreign Currency - The functional currencies of the Company’s international subsidiaries are generally the local currencies of the countries in which the subsidiaries are located. Foreign currency denominated assets and liabilities are translated into U.S. dollars using the exchange rates in effect at the balance sheet date. Results of operations and cash flows are translated using the average exchange rates throughout the period. The effect of exchange rate fluctuations on translation of assets and liabilities is included as a component of shareholders’ equity in accumulated other comprehensive income/loss. Gains and losses from foreign currency transactions are included in selling, general and administrative (SG&A) expense. Use of Estimates - The preparation of the Company’s financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates that affect the reported amounts of assets, liabilities, sales and expenses, and related disclosures of contingent assets and liabilities. The Company bases these estimates on historical results and various other assumptions believed to be reasonable, all of which form the basis for making estimates concerning the carrying values of assets and liabilities that are not readily available from other sources. Actual results may differ from these estimates. Cash and Cash Equivalents - Cash and cash equivalents include cash on hand, demand deposits, and short-term investments with original maturities of three months or less when purchased. Cash and cash equivalents are carried at amortized cost on the consolidated balance sheets. The majority of payments due from financial institutions for the settlement of credit card and debit card transactions process within two business days and are, therefore, classified as cash and cash equivalents. Investments - Investments generally consist of money market funds, municipal obligations, certificates of deposit, and municipal floating rate obligations, all of which are classified as available-for-sale. Available-for-sale securities are recorded at fair value, and unrealized gains and losses are recorded, net of tax, as a component of accumulated other comprehensive income/loss. Gross unrealized gains and losses were insignificant at February 2, 2018 and February 3, 2017 . The proceeds from sales of available-for-sale securities were $523 million , $505 million , and $394 million for 2017 , 2016 , and 2015 , respectively. Gross realized gains and losses on the sale of available-for-sale securities were not significant for any of the periods presented. Investments with a stated maturity date of one year or less from the balance sheet date or that are expected to be used in current operations are classified as short-term investments. All other investments are classified as long-term. Investments classified as long-term at February 2, 2018 , will mature in one to 37 years, based on stated maturity dates. The Company classifies as investments restricted balances primarily pledged as collateral for the Company’s extended protection plan program. Restricted balances included in short-term investments were $86 million at February 2, 2018 , and $81 million at February 3, 2017 . Restricted balances included in long-term investments were $381 million at February 2, 2018 , and $354 million at February 3, 2017 . Merchandise Inventory - The majority of the Company’s inventory is stated at the lower of cost and net realizable value using the first-in, first-out method of inventory accounting. Inventory for certain subsidiaries representing approximately 10% and 8% of the consolidated inventory balances as of February 2, 2018 and February 3, 2017 , respectively, are stated at lower of cost and net realizable value using other inventory methods, including the weighted average cost method and the retail inventory method. The cost of inventory includes certain costs associated with the preparation of inventory for resale, including distribution center costs, and is net of vendor funds. The Company records an inventory reserve for the anticipated loss associated with selling inventories below cost. This reserve is based on management’s current knowledge with respect to inventory levels, sales trends, and historical experience. Management does not believe the Company’s merchandise inventories are subject to significant risk of obsolescence in the near term, and management has the ability to adjust purchasing practices based on anticipated sales trends and general economic conditions. However, changes in consumer purchasing patterns could result in the need for additional reserves. The Company also records an inventory reserve for the estimated shrinkage between physical inventories. This reserve is based primarily on actual shrink results from previous physical inventories. Changes in the estimated shrink reserve are made based on the timing and results of physical inventories. The Company receives funds from vendors in the normal course of business, principally as a result of purchase volumes, sales, early payments, or promotions of vendors’ products. Generally, these vendor funds do not represent the reimbursement of specific, incremental, and identifiable costs incurred by the Company to sell the vendor’s product. Therefore, the Company treats these funds as a reduction in the cost of inventory, and are recognized as a reduction of cost of sales when the inventory is sold. Funds that are determined to be reimbursements of specific, incremental, and identifiable costs incurred to sell vendors’ products are recorded as an offset to the related expense. The Company develops accrual rates for vendor funds based on the provisions of the agreements in place. Due to the complexity and diversity of the individual vendor agreements, the Company performs analyses and reviews historical trends throughout the year and confirms actual amounts with select vendors to ensure the amounts earned are appropriately recorded. Amounts accrued throughout the year could be impacted if actual purchase volumes differ from projected annual purchase volumes, especially in the case of programs that provide for increased funding when graduated purchase volumes are met. Credit Programs - The Company has an agreement with Synchrony Bank (Synchrony), formerly GE Capital Retail, under which Synchrony purchases at face value commercial business accounts receivable originated by the Company and services these accounts. This agreement expires in December 2023, unless terminated sooner by the parties. The Company primarily accounts for these transfers as sales of the accounts receivable. When the Company transfers its commercial business accounts receivable, it retains certain interests in those receivables, including the funding of a loss reserve and its obligation related to Synchrony’s ongoing servicing of the receivables sold. Any gain or loss on the sale is determined based on the previous carrying amounts of the transferred assets allocated at fair value between the receivables sold and the interests retained. Fair value is based on the present value of expected future cash flows, taking into account the key assumptions of anticipated credit losses, payment rates, late fee rates, Synchrony’s servicing costs, and the discount rate commensurate with the uncertainty involved. Due to the short-term nature of the receivables sold, changes to the key assumptions would not materially impact the recorded gain or loss on the sales of receivables or the fair value of the retained interests in the receivables. Total commercial business accounts receivable sold to Synchrony were $3.1 billion in 2017 , $2.8 billion in 2016 , and $2.6 billion in 2015 . The Company recognized losses of $39 million in 2017 , $32 million in 2016 , and $36 million in 2015 on these receivable sales as SG&A expense, which primarily relates to the fair value of obligations related to servicing costs that are remitted to Synchrony monthly. At February 2, 2018 and February 3, 2017 , the fair value of the retained interests was determined based on the present value of expected future cash flows and was insignificant. Sales generated through the Company’s proprietary credit cards are not reflected in receivables. Under an agreement with Synchrony, credit is extended directly to customers by Synchrony. All credit program-related services are performed and controlled directly by Synchrony. The Company has the option, but no obligation, to purchase the receivables at the end of the agreement in December 2023. Tender costs, including amounts associated with accepting the Company’s proprietary credit cards, are included in SG&A expense in the consolidated statements of earnings. The total portfolio of receivables held by Synchrony, including both receivables originated by Synchrony from the Company’s proprietary credit cards and commercial business accounts receivable originated by the Company and sold to Synchrony, approximated $10.2 billion at February 2, 2018 , and $9.6 billion at February 3, 2017 . Property and Depreciation - Property is recorded at cost. Costs associated with major additions are capitalized and depreciated. Capital assets are expected to yield future benefits and have original useful lives which exceed one year. The total cost of a capital asset generally includes all applicable sales taxes, delivery costs, installation costs, and other appropriate costs incurred by the Company, including interest in the case of self-constructed assets. Upon disposal, the cost of properties and related accumulated depreciation is removed from the accounts, with gains and losses reflected in SG&A expense in the consolidated statements of earnings. Property consists of land, buildings and building improvements, equipment, and construction in progress. Buildings and building improvements includes owned buildings, as well as buildings under capital lease and leasehold improvements. Equipment primarily includes store racking and displays, computer hardware and software, forklifts, vehicles, and other store equipment . Depreciation is provided over the estimated useful lives of the depreciable assets. Assets are depreciated using the straight-line method. Leasehold improvements and assets under capital lease are depreciated over the shorter of their estimated useful lives or the term of the related lease, which may include one or more option renewal periods where failure to exercise such options would result in an economic penalty in such amount that renewal appears, at the inception of the lease, to be reasonably assured. During the term of a lease, if leasehold improvements are placed in service significantly after the inception of the lease, the Company depreciates these leasehold improvements over the shorter of the useful life of the leasehold assets or a term that includes lease renewal periods deemed to be reasonably assured at the time the leasehold improvements are placed into service. The amortization of these assets is included in depreciation expense in the consolidated financial statements. Long-Lived Asset Impairment/Exit Activities - The carrying amounts of long-lived assets are reviewed whenever certain events or changes in circumstances indicate that the carrying amounts may not be recoverable. A potential impairment has occurred for long-lived assets held-for-use if projected future undiscounted cash flows expected to result from the use and eventual disposition of the assets are less than the carrying amounts of the assets. An impairment loss is recorded for long-lived assets held-for-use when the carrying amount of the asset is not recoverable and exceeds its fair value. Excess properties that are expected to be sold within the next 12 months and meet the other relevant held-for-sale criteria are classified as long-lived assets held-for-sale. Excess properties consist primarily of retail outparcels and property associated with relocated or closed locations. An impairment loss is recorded for long-lived assets held-for-sale when the carrying amount of the asset exceeds its fair value less cost to sell. A long-lived asset is not depreciated while it is classified as held-for-sale. For long-lived assets to be abandoned, the Company considers the asset to be disposed of when it ceases to be used. Until it ceases to be used, the Company continues to classify the asset as held-for-use and tests for potential impairment accordingly. If the Company commits to a plan to abandon a long-lived asset before the end of its previously estimated useful life, its depreciable life is re-evaluated. Impairment losses are included in SG&A expense in the consolidated statements of earnings. Fair value measurements associated with long-lived asset impairments are further described in Note 4 to the consolidated financial statements. When locations under operating leases are closed, a liability is recognized for the fair value of future contractual obligations, including future minimum lease payments, property taxes, utilities, common area maintenance, and other ongoing expenses, net of estimated sublease income and other recoverable items. When the Company commits to an exit plan and communicates that plan to affected employees, a liability is recognized in connection with one-time employee termination benefits. Subsequent changes to the liabilities, including a change resulting from a revision to either the timing or the amount of estimated cash flows, are recognized in the period of change. Expenses associated with exit activities are included in SG&A expense in the consolidated statement of earnings. Amounts accrued for exit activities were not material for any of the periods presented. Goodwill - Goodwill is the excess of the purchase price over the fair value of identifiable assets acquired, less liabilities assumed, in a business combination. The Company reviews goodwill for impairment at the reporting unit level, which is one level below the operating segment level. Goodwill is not amortized but is evaluated for impairment at least annually on the first day of the fourth quarter or whenever events or changes in circumstances indicate that it is more likely than not that the carrying amount may not be recoverable. The evaluation begins with a qualitative assessment to determine whether a quantitative impairment test is necessary. If, after assessing qualitative factors, we determine it is more likely than not that the fair value of the reporting unit is less than the carrying amount, then the two-step goodwill impairment test is necessary. The first step of the goodwill impairment test used to identify potential impairment compares the fair value of a reporting unit with its carrying amount, including goodwill. Fair value represents the price a market participant would be willing to pay in a potential sale of the reporting unit and is based on discounted future cash flows. If the fair value exceeds carrying value, then no goodwill impairment has occurred. If the carrying value of the reporting unit exceeds its fair value, a second step is required to measure possible goodwill impairment loss. The second step includes hypothetically valuing the tangible and intangible assets and liabilities of the reporting unit as if the reporting unit had been acquired in a business combination. Then, the implied fair value of the reporting unit’s goodwill is compared to the carrying value of that goodwill. If the carrying value of the reporting unit’s goodwill exceeds the implied fair value of the goodwill, an impairment loss is recognized in an amount equal to the excess, not to exceed the carrying value. A reporting unit is an operating segment or a business unit one level below that operating segment, for which discrete financial information is prepared and regularly reviewed by segment management. Goodwill is allocated to the following reporting units: U.S. Home Improvement, Orchard Supply Hardware (Orchard), Canada - Retail, and Canada - Distribution. The changes in the carrying amount of goodwill for 2017 , 2016 , and 2015 were as follows: (In millions) 2017 2016 2015 Goodwill, balance at beginning of year $ 1,082 $ 154 $ 154 Acquisitions 1 160 1,015 — Impairment — (46 ) — Other adjustments 2 65 (41 ) — Goodwill, balance at end of year $ 1,307 $ 1,082 $ 154 1 Goodwill recorded for 2017 acquisitions relates to Maintenance Supply Headquarters. Goodwill recorded for 2016 acquisitions primarily relates to RONA. See Note 2 for additional information regarding these acquisitions. 2 Other adjustments primarily consist of changes in the goodwill balance as a result of foreign currency translation. During the third quarter of fiscal year 2016, due to a strategic reassessment of the Orchard operations, the Company determined potential indicators of impairment within the reporting unit existed, and quantitatively evaluated the Orchard reporting unit for impairment. The Company classified this fair value measurement as Level 3. See Note 4 for additional information on the Company’s fair value measurements. The Company performed a discounted cash flow analysis for the Orchard reporting unit. The discounted cash flow model included management assumptions for expected sales growth, expansion plans, capital expenditures, and overall operational forecasts. The analysis led to the conclusion that the goodwill allocated to the Orchard reporting unit had no implied value. Accordingly, the full carrying value of $46 million relating to Orchard goodwill was impaired during the third quarter of 2016. Gross carrying amounts and cumulative goodwill impairment losses are as follows: February 2, 2018 February 3, 2017 (In millions) Gross Carrying Amount Cumulative Impairment Gross Carrying Amount Cumulative Impairment Goodwill $ 1,354 $ (47 ) $ 1,129 $ (47 ) Equity Method Investments - The Company’s investments in certain unconsolidated entities are accounted for under the equity method. The balance of these investments is included in other assets (noncurrent) in the accompanying consolidated balance sheets. The balance is increased to reflect the Company’s capital contributions and equity in earnings of the investees. The balance is decreased for its equity in losses of the investees, for distributions received that are not in excess of the carrying amount of the investments, and for any other than temporary impairment losses recognized. Equity method investments were not significant as of February 2, 2018 and February 3, 2017 . The Company’s equity in earnings and losses of the investees are included in SG&A expense, and were not significant for any of the periods presented. Equity method investments are evaluated for impairment whenever events or changes in circumstances indicate that a decline in value has occurred that is other than temporary. Evidence considered in this evaluation includes, but would not necessarily be limited to, the financial condition and near-term prospects of the investee, recent operating trends and forecasted performance of the investee, market conditions in the geographic area or industry in which the investee operates and the Company’s strategic plans for holding the investment in relation to the period of time expected for an anticipated recovery of its carrying value. Investments that are determined to have a decline in value deemed to be other than temporary are written down to estimated fair value. The Company’s other than temporary impairment losses are included in SG&A expense, and were not significant for 2017 and 2016 . See Note 3 for additional information on the other than temporary impairment loss the Company recognized in 2015 , related to its investment in the Australian joint venture. Leases - For lease agreements that provide for escalating rent payments or free-rent occupancy periods, the Company recognizes rent expense on a straight-line basis over the non-cancellable lease term and option renewal periods where failure to exercise such options would result in an economic penalty in such amount that renewal appears, at the inception of the lease, to be reasonably assured. The lease term commences on the date that the Company takes possession of or controls the physical use of the property. Deferred rent is included in other liabilities (noncurrent) on the consolidated balance sheets. When the Company renegotiates and amends a lease to extend the non-cancellable lease term prior to the date at which it would have been required to exercise or decline a term extension option, the amendment is treated as a new lease. The new lease begins on the date the lease amendment is entered into and ends on the last date of the non-cancellable lease term, as adjusted to include any option renewal periods where failure to exercise such options would result in an economic penalty in such amount that renewal appears, at the inception of the lease amendment, to be reasonably assured. The new lease is classified as operating or capital under the authoritative guidance through use of assumptions regarding residual value, economic life, incremental borrowing rate, and fair value of the leased asset(s) as of the date of the amendment. Accounts Payable - The Company has an agreement with a third party to provide an accounts payable tracking system which facilitates participating suppliers’ ability to finance payment obligations from the Company with designated third-party financial institutions. Participating suppliers may, at their sole discretion, make offers to finance one or more payment obligations of the Company prior to their scheduled due dates at a discounted price to participating financial institutions. The Company’s goal in entering into this arrangement is to capture overall supply chain savings, in the form of pricing, payment terms, or vendor funding, created by facilitating suppliers’ ability to finance payment obligations at more favorable discount rates, while providing them with greater working capital flexibility. The Company’s obligations to its suppliers, including amounts due and scheduled payment dates, are not impacted by suppliers’ decisions to finance amounts under this arrangement. However, the Company’s right to offset balances due from suppliers against payment obligations is restricted by this arrangement for those payment obligations that have been financed by suppliers. The Company’s outstanding payment obligation placed on the accounts payable tracking system were $1.6 billion as of February 2, 2018 and February 3, 2017 , and participating suppliers had financed $1.1 billion and $1.0 billion , respectively, of those payment obligations to participating financial institutions. Other Current Liabilities - Other current liabilities on the consolidated balance sheets consist of: (In millions) February 2, 2018 February 3, 2017 Self-insurance liabilities $ 347 $ 327 Accrued dividends 340 304 Accrued interest 184 194 Sales tax liabilities 144 210 Accrued property taxes 109 108 Other 826 832 Total $ 1,950 $ 1,975 Self-Insurance - The Company is self-insured for certain losses relating to workers’ compensation, automobile, property, and general and product liability claims. The Company has insurance coverage to limit the exposure arising from these claims. The Company is also self-insured for certain losses relating to extended protection plan and medical and dental claims. Self-insurance claims filed and claims incurred but not reported are accrued based upon management’s estimates of the discounted ultimate cost for self-insured claims incurred using actuarial assumptions followed in the insurance industry and historical experience. Although management believes it has the ability to reasonably estimate losses related to claims, it is possible that actual results could differ from recorded self-insurance liabilities. The total self-insurance liability, including the current and non-current portions, was $890 million and $831 million at February 2, 2018 , and February 3, 2017 , respectively. The Company provides surety bonds issued by insurance companies to secure payment of workers’ compensation liabilities as required in certain states where the Company is self-insured. Outstanding surety bonds relating to self-insurance were $238 million and $243 million at February 2, 2018 , and February 3, 2017 , respectively. Income Taxes - The Company establishes deferred income tax assets and liabilities for temporary differences between the tax and financial accounting bases of assets and liabilities. The tax effects of such differences are reflected in the consolidated balance sheets at the enacted tax rates expected to be in effect when the differences reverse. A valuation allowance is recorded to reduce the carrying amount of deferred tax assets if it is more likely than not that all or a portion of the asset will not be realized. The tax balances and income tax expense recognized by the Company are based on management’s interpretation of the tax statutes of multiple jurisdictions. The Company establishes a liability for tax positions for which there is uncertainty as to whether or not the position will be ultimately sustained. The Company includes interest related to tax issues as part of net interest on the consolidated financial statements. The Company records any applicable penalties related to tax issues within the income tax provision. Shareholders’ Equity - The Company has a share repurchase program that is executed through purchases made from time to time either in the open market or through private market transactions. Shares purchased under the repurchase program are retired and returned to authorized and unissued status. Any excess of cost over par value is charged to additional paid-in capital to the extent that a balance is present. Once additional paid-in capital is fully depleted, remaining excess of cost over par value is charged to retained earnings. Revenue Recognition - The Company recognizes revenues, net of sales tax, when sales transactions occur and customers take possession of the merchandise. A provision for anticipated merchandise returns is provided through a reduction of sales and cost of sales in the period that the related sales are recorded. Revenues from product installation services are recognized when the installation is completed. Deferred revenues associated with amounts received for which customers have not yet taken possession of merchandise or for which installation has not yet been completed were $831 million and $755 million at February 2, 2018 , and February 3, 2017 , respectively. Revenues from stored-value cards, which include gift cards and returned merchandise credits, are deferred and recognized when the cards are redeemed. The liability associated with outstanding stored-value cards was $547 million and $498 million at February 2, 2018 , and February 3, 2017 , respectively, and these amounts are included in deferred revenue on the consolidated balance sheets. The Company recognizes income from unredeemed stored-value cards at the point at which redemption becomes remote. The Company’s stored-value cards have no expiration date or dormancy fees. Therefore, to determine when redemption is remote, the Company analyzes an aging of the unredeemed cards based on the date of last stored-value card use. The amount of revenue recognized from unredeemed stored-value cards for which redemption was deemed remote was not significant for 2017 , 2016 , and 2015 . Extended Protection Plans - The Company sells separately-priced extended protection plan contracts under a Lowe’s-branded program for which the Company is ultimately self-insured. The Company recognizes revenue from extended protection plan sales on a straight-line basis over the respective contract term. Extended protection plan contract terms primarily range from one to four years from the date of purchase or the end of the manufacturer’s warranty, as applicable. Changes in deferred revenue for extended protection plan contracts are summarized as follows: (In millions) 2017 2016 2015 Deferred revenue - extended protection plans, beginning of year $ 763 $ 729 $ 730 Additions to deferred revenue 408 387 350 Deferred revenue recognized (368 ) (353 ) (351 ) Deferred revenue - extended protection plans, end of year $ 803 $ 763 $ 729 Incremental direct acquisition costs associated with the sale of extended protection plans are also deferred and recognized as expense on a straight-line basis over the respective contract term. Deferred costs associated with extended protection plan contracts were $19 million and $18 million at February 2, 2018 , and February 3, 2017 , respectively. The Company’s extended protection plan deferred costs are included in other assets (noncurrent) on the consolidated balance sheets. All other costs, such as costs of services performed under the contract, general and administrative expenses, and advertising expenses are expensed as incurred. The liability for extended protection plan claims incurred is included in other current liabilities on the consolidated balance sheets and was not material in any of the years presented. Expenses for claims are recognized when incurred and totaled $161 million , $141 million , and $127 million for 2017 , 2016 , and 2015 , respectively. Cost of Sales and Selling, General and Administrative Expenses - The following lists the primary costs classified in each major expense category: Cost of Sales Selling, General and Administrative n Total cost of products sold, including: - Purchase costs, net of vendor funds; - Freight expenses associated with moving merchandise inventories from vendors to selling locations; - Costs associated with operating the Company’s distribution network, including payroll and benefit costs and occupancy costs; n Costs of installation services provided; n Costs associated with delivery of products directly from vendors to customers by third parties; n Costs associated with inventory shrinkage and obsolescence; n Costs of services performed under the extended protection plan. n Payroll and benefit costs for retail and corporate employees; n Occupancy costs of retail and corporate facilities; n Advertising; n Costs associated with delivery of products from stores and distribution centers to customers; n Third-party, in-store service costs; n Tender costs, including bank charges, costs associated with credit card interchange fees and amounts associated with accepting the Company’s proprietary credit cards; n Costs associated with self-insured plans, and premium costs for stop-loss coverage and fully insured plans; n Long-lived asset impairment losses and gains/losses on disposal of assets; n Other administrative costs, such as supplies, and travel and entertainment. Advertising - Costs associated with advertising are charged to expense as incurred. Advertising expenses were $968 million , $893 million , and $769 million in 2017 , 2016 , and 2015 , respectively. Shipping and Handling Costs - The Company includes shipping and handling costs relating to the delivery of products directly from vendors to customers by third parties in cost of sales. Shipping and handling costs, which include third-party delivery costs, salaries, and vehicle operations expenses relating to the delivery of products from stores and distribution centers to customers, are classified as SG&A expense. Shipping and handling costs included in SG&A expense were $841 million , $700 million and $607 million in 2017 , 2016 , and 2015 , respectively. Store Opening Costs - Costs of opening new or relocated retail stores, which include payroll and supply costs incurred prior to store opening and grand opening advertising costs, are charged to expense |
