SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract] |
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES INDUSTRY INFORMATION W.W. Grainger, Inc. is a broad line distributor of maintenance, repair and operating supplies, and other related products and services used by businesses and institutions. In this report, the words “Company” or “Grainger” mean W.W. Grainger, Inc. and its subsidiaries. PRINCIPLES OF CONSOLIDATION The Consolidated Financial Statements include the accounts of the Company and its subsidiaries over which the Company exercises control. All significant intercompany transactions are eliminated from the consolidated financial statements. The Company has a 51% ownership in MonotaRO Co., with the residual representing the noncontrolling interest. USE OF ESTIMATES The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and the disclosure of contingent liabilities. Actual results could differ from those estimates. FOREIGN CURRENCY TRANSLATION The U.S. dollar is the reporting currency for all periods presented. The financial statements of the Company’s foreign operating subsidiaries are measured using the local currency as the functional currency. Assets and liabilities of the Company’s foreign operating subsidiaries are translated into U.S. dollars at the exchange rate in effect at the balance sheet date. Revenues and expenses are translated at average rates in effect during the period. Net exchange gains or losses resulting from the translation of financial statements of foreign operations and related long-term debt are recorded as a separate component of other comprehensive earnings. See Note 13 to the Consolidated Financial Statements. Foreign currency transaction gains and losses are included in the Consolidated Statement of Earnings. RECLASSIFICATIONS Certain amounts in the 2015 and 2014 financial statements, as previously reported, have been reclassified to conform to the 2016 presentation. See Note 3 to the Consolidated Financial Statements. These changes did not have a material impact on the Consolidated Financial Statements. REVENUE RECOGNITION Revenues recognized include product sales, billings for freight and handling charges and fees earned for services provided. The Company recognizes product sales and billings for freight and handling charges primarily on the date products are shipped to, or picked up by, the customer. In cases where the product is shipped directly to the customer, the Company recognizes revenue at the time of shipment primarily on a gross basis. The Company's standard shipping terms are FOB shipping point. On occasion, the Company will negotiate FOB destination terms. These sales are recognized upon delivery to the customer. eCommerce revenues, which accounted for 47% of total 2016 revenues, are recognized on the same terms as revenues through other channels. Fee revenues, which accounted for less than 1% of total 2016 revenues, are recognized after services are completed including related service costs. Taxes collected from customers and remitted to governmental authorities are presented on a net basis and are not included in revenue. COST OF MERCHANDISE SOLD Cost of merchandise sold includes product and product-related costs, vendor consideration, freight-out and handling costs. The Company defines handling costs as those costs incurred to fulfill a shipped sales order. VENDOR CONSIDERATION The Company receives rebates and allowances from its vendors to promote their products. The Company utilizes numerous advertising programs to promote its vendors' products, including catalogs and other printed media, Internet, radio and other marketing programs. Most of these programs relate to multiple vendors, which makes supporting the specific, identifiable and incremental criteria difficult, and would require numerous assumptions and judgments. Based on the inexact nature of trying to track reimbursements to the advertising expenditure for each vendor, the Company treats most vendor advertising allowances as a reduction to product purchase price and is reflected in Cost of merchandise sold rather than a reduction of operating (advertising) expenses. Vendor funds that are determined to be reimbursement of specific, incremental and identifiable costs incurred to promote vendors' products are recorded as an offset to the related expenses in Warehouse, marketing and administrative expenses. Rebates earned from vendors that are based on product purchases are capitalized into inventory as part of product purchase price. These rebates are credited to Cost of merchandise sold based on sales. Vendor rebates that are earned based on products sold are credited directly to Cost of merchandise sold. ADVERTISING Advertising costs are expensed in the year the related advertisement is first presented. Advertising expense was $180 million, $180 million and $169 million for 2016, 2015 and 2014, respectively. Most vendor-provided allowances are classified as a reduction to product purchase price and is reflected in Cost of merchandise sold. For additional information see VENDOR CONSIDERATION above. Catalog expense is amortized equally over the life of the catalog, beginning in the month of its distribution. Advertising costs for catalogs that have not been distributed by year-end are capitalized as Prepaid expenses. Amounts included in Prepaid expenses at December 31, 2016 and 2015, were $12 million and $19 million, respectively. WAREHOUSING, MARKETING AND ADMINISTRATIVE EXPENSES Included in this category are purchasing, branch operations, information services and marketing and selling expenses, as well as other types of general and administrative costs. STOCK INCENTIVE PLANS The Company measures all share-based payments using fair-value-based methods and records compensation expense related to these payments over the vesting period. See Note 11 to the Consolidated Financial Statements. INCOME TAXES Income taxes are recognized during the year in which transactions enter into the determination of financial statement income, with deferred taxes being provided for temporary differences between financial and tax reporting. The Company recognizes in the financial statements a provision for tax uncertainties, resulting from application of complex tax regulations in multiple tax jurisdictions. The Company evaluates our deferred income taxes to determine if valuation allowances are required using a “more likely than not” standard. This assessment considers the nature, frequency and amount of book and taxable income and losses, the duration of statutory carryback and forward periods, future reversals of existing taxable temporary differences and tax planning strategies, among other matters. See Note 14 to the Consolidated Financial Statements. OTHER COMPREHENSIVE EARNINGS (LOSSES) The Company's Other comprehensive earnings (losses) include foreign currency translation adjustments, changes in fair value of derivatives designated as hedges and unrecognized gains (losses) on postretirement and other employment-related benefit plans. Accumulated other comprehensive earnings (losses) (AOCE) are presented separately as part of shareholders' equity. See Note 13 to the Consolidated Financial Statements. CASH AND CASH EQUIVALENTS The Company considers investments in highly liquid debt instruments, purchased with an original maturity of 90 days or less, to be cash equivalents. CONCENTRATION OF CREDIT RISK The Company places temporary cash investments with institutions of high credit quality and, by policy, limits the amount of credit exposure to any one institution. The Company has a broad customer base representing many diverse industries doing business in all regions of the United States, Canada, Europe, Asia and Latin America. Consequently, no significant concentration of credit risk is considered to exist. ACCOUNTS RECEIVABLE AND ALLOWANCE FOR DOUBTFUL ACCOUNTS Accounts receivable are stated at their estimated net realizable value. The Company establishes reserves for customer accounts that are potentially uncollectible. The method used to estimate the allowances is based on several factors, including the age of the receivables and the historical ratio of actual write-offs to the age of the receivables. These analyses also take into consideration economic conditions that may have an impact on a specific industry, group of customers or a specific customer. See Note 4 to the Consolidated Financial Statements. INVENTORIES Inventories are valued at the lower of cost or market. Cost is determined primarily by the last-in, first-out (LIFO) method, which accounts for approximately 64% of total inventory. For the remaining inventory, cost is determined by the first-in, first-out (FIFO) method. Grainger establishes inventory reserves for obsolete inventory. Grainger regularly reviews inventory to evaluate continued demand and identify any obsolete or excess quantities. Grainger records provisions for the difference between excess and obsolete inventory cost and its estimated realizable value. PROPERTY, BUILDINGS AND EQUIPMENT Property, buildings and equipment are valued at cost. For financial statement purposes, depreciation and amortization are recorded in amounts sufficient to relate the cost of depreciable assets to operations over their estimated service lives, principally on the declining-balance and sum-of-the-years-digits depreciation methods. The Company's international businesses record depreciation expense primarily on a straight-line basis. The principal estimated useful lives for determining depreciation are as follows:
Buildings, structures and improvements | 10 to 30 years
Furniture, fixtures, machinery and equipment | 3 to 10 years
Depreciation expense was $166 million, $162 million and $154 million for the years ended December 31, 2016, 2015 and 2014, respectively. Improvements to leased property are amortized over the initial terms of the respective leases or the estimated service lives of the improvements, whichever is shorter. The Company capitalized interest costs of $2 million, $4 million and $2 million for the years ended December 31, 2016, 2015 and 2014, respectively. LONG-LIVED ASSETS The carrying value of long-lived assets, primarily property, buildings and equipment and amortizable intangibles, is evaluated whenever events or changes in circumstances indicate that the carrying value of the asset may be impaired. An impairment loss is recognized when estimated undiscounted future cash flows resulting from use of the asset, including disposition, are less than the carrying value of the asset. Impairment is measured as the amount by which the asset's carrying amount exceeds the fair value. GOODWILL AND OTHER INTANGIBLES Goodwill is recognized as the excess cost of an acquired entity over the net amount assigned to assets acquired and liabilities assumed. Goodwill is not amortized, but rather tested for impairment on an annual basis and more often if circumstances require. Impairment losses are recognized whenever the implied fair value of goodwill is less than its carrying value. The Company recognizes an acquired intangible apart from goodwill whenever the intangible arises from contractual or other legal rights, or whenever it can be separated or divided from the acquired entity and sold, transferred, licensed, rented or exchanged, either individually or in combination with a related contract, asset or liability. Such intangibles are amortized over their estimated useful lives unless the estimated useful life is determined to be indefinite. The straight-line method of amortization is used as it has been determined to approximate the use pattern of the asset. The Company also maintains intangible assets with indefinite lives, which are not amortized. These intangibles are tested for impairment on an annual basis and more often if circumstances require. Impairment losses are recognized whenever the estimated fair value of these assets is less than their carrying value. See Note 3 to the Consolidated Financial Statements. The Company capitalizes certain costs related to the purchase and development of internal-use software. Amortization of capitalized software is on a straight-line basis over three or five years. FAIR VALUE OF FINANCIAL INSTRUMENTS The carrying amounts of cash and cash equivalents, receivables and accounts payable approximate fair value due to the short-term nature of these financial instruments. See Note 8 to the Consolidated Financial Statements for fair value of long-term debt. WARRANTY RESERVES The Company generally warrants the products it sells against defects for one year. For a significant portion of warranty claims, the manufacturer of the product is responsible for expenses. For warranty expenses not covered by the manufacturer, the Company provides a reserve for future costs based primarily on historical experience. Warranty reserves were $3 million at December 31, 2016 and 2015. CONTINGENCIES The Company accrues for costs relating to litigation claims and other contingent matters, when it is probable that a liability has been incurred and the amount of the assessment can be reasonably estimated. NEW ACCOUNTING STANDARDS In July 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Board (ASU) 2015-11, Simplifying the Measurement of Inventory, which simplifies the subsequent measurement of inventory by replacing the lower of cost or market test with a lower of cost or net realizable value (NRV) test. NRV is calculated as the estimated selling price less reasonably predictable costs of completion, disposal and transportation. This ASU is effective for fiscal years and for interim periods within those fiscal years beginning after December 15, 2016, and prospective adoption is required. This ASU is not expected to have a material impact on the Company's Consolidated Financial Statements. In January 2016, the FASB issued ASU 2016-01, Financial Instruments: Recognition and Measurement of Financial Assets and Financial Liabilities. This change to the financial instrument model primarily affects the accounting for equity investments, financial liabilities under fair value options and the presentation and disclosure requirements for financial instruments. The effective date for the standard is for fiscal years and interim periods within those years beginning after December 15, 2017. Certain provisions of the new guidance can be adopted early. The Company is evaluating the impact of this ASU. In February 2016, the FASB issued ASU 2016-02, Leases. This ASU improves transparency and comparability related to the accounting and reporting of leasing arrangements. The guidance will require balance sheet recognition for assets and liabilities associated with rights and obligations created by leases with terms greater than twelve months. The effective date for the standard is for fiscal years and interim periods within those years beginning after December 15, 2018. Early adoption is permitted. The Company is evaluating the impact of this ASU. In March 2016, the FASB issued ASU 2016-07, Investments - Equity Method and Joint Ventures: Simplifying the Transition to the Equity Method of Accounting.This ASU eliminates the requirement to retroactively adjust the investment, results of operations and retained earnings when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence. The amendment requires that the investor add the cost of acquiring the additional interest to the current basis of the investor's previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. The effective date for the standard is for fiscal years and interim periods within those years beginning after December 15, 2016. The amendment should be applied prospectively and early application is permitted. This ASU is not expected to have a material impact on the Company's Consolidated Financial Statements. In March 2016, the FASB issued ASU 2016-09, Stock Based Compensation: Improvements to Employee Share-Based Payment Accounting. This ASU simplifies several aspects of the accounting for employee share-based payment transactions, including accounting for income taxes, forfeitures and statutory tax withholdings requirements, as well as classification in the statement of cash flows. The effective date for the standard is for fiscal years and interim periods within those years beginning after December 15, 2016. Early adoption is permitted. If early adoption is elected, all amendments in the ASU that apply must be adopted in the same period. The Company has elected not to early adopt this ASU. The Company expects the new guidance to impact its tax expense and dilutive shares outstanding calculation, with a potentially dilutive impact on future earnings per share and increased period-to-period variability of net earnings. The impact cannot be quantified due to the timing and exercise activity that will occur in future periods. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments. This ASU affects an entity to varying degrees depending on the credit quality of the assets held by the entity, their duration and how the entity applies current GAAP. The effective date of the amendment to the standard is for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company is evaluating the impact of this ASU. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows - Classification of Certain Cash Receipts and Cash Payments. This ASU addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. The effective date of the amendment to the standard is for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. This ASU is not expected to have a material impact on the Company's Consolidated Financial Statements. In October 2016, the FASB issued ASU 2016-16, Income Taxes - Intra-Entity Transfers of Assets Other Than Inventory. This ASU eliminates the existing exception in U.S. GAAP that prohibits the recognition of income tax consequences for most intra-entity asset transfers. The effective date of this ASU is fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. This ASU is not expected to have a material impact on the Company's Consolidated Financial Statements. In October 2016, the FASB issued ASU 2016-17, Consolidation - Interests Held Through Related Parties That Are Under Common Control. This ASU amends the consolidation guidance on how a reporting entity that is the single decision maker of a variable interest entity (VIE) should treat indirect interests in the entity held through related parties that are under common control with the reporting entity when determining whether it is the primary beneficiary of that VIE. The effective date of the amendment to the standard is for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. This ASU is not expected to have a material impact on the Company's Consolidated Financial Statements. In December 2016, the FASB issued ASU 2016-19, Technical Corrections and Improvements. This ASU represents changes to clarify, correct errors or make minor improvements to the Accounting Standards Codification. The amendments make the Accounting Standards Codification easier to understand and easier to apply by eliminating inconsistencies and providing clarifications. Most of the amendments in this Update do not require transition guidance and are effective upon issuance of this Update. Six amendments in this Update clarify guidance or correct references in the Accounting Standards Codification that could potentially result in changes in current practice because of either misapplication or misunderstanding of current guidance. Early adoption is permitted for the amendments that require transition guidance. This ASU is not expected to have a material impact on the Company's Consolidated Financial Statements. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. This ASU clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill and consolidation. The effective date of this ASU is for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company is evaluating the impact of this ASU. In January 2017, the FASB issued ASU 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This ASU is to simplify how an entity is required to test goodwill for impairment. The effective date of the amendment to the standard is for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company's goodwill impairment testing for the fiscal period beginning January 1, 2018, will follow the provisions of this ASU. REVENUE RECOGNITION STANDARDS In July 2015, FASB announced a one-year delay in the effective date of ASU 2014-09, Revenue from Contracts with Customers. This ASU will now be effective for interim and annual periods beginning after December 15, 2017. The standard will supersede nearly all existing revenue recognition guidance under U.S. GAAP. The core principle of the ASU is that an entity should recognize revenue when it transfers 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. The ASU also requires additional disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The standard permits adoption as early as the original effective date, which was for interim and annual periods beginning after December 15, 2016. In March 2016, the FASB issued ASU 2016-08, Revenue from Contract with Customers: Principal versus Agent Considerations (Reporting Revenue Gross versus Net). This ASU is meant to reduce the potential for diversity in practice arising from inconsistent application of the principal versus agent guidance as well as reduce the cost and complexity during the transition and on an ongoing basis. In April 2016, the FASB issued ASU 2016-10, Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing. This ASU is meant to clarify the identification of performance obligations and the licensing implementation guidelines, while retaining the related principles of those areas. In December 2016, the FASB issued ASU 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers. This ASU includes technical corrections and improvements to Topic 606 and other Topics amended by Update 2014-09 to increase stakeholders’ awareness of the proposals and to expedite improvements to ASU 2014-09. The effective dates of ASU 2016-08, ASU 2016-10 and ASU 2016-20 are consistent with ASU 2014-09. The Company has elected not to early adopt these ASUs. The standard permits the use of either the full retrospective or the modified retrospective adoption method. The Company is planning to elect the modified retrospective method and recognize the cumulative effect of initially applying the new standard as an adjustment to the opening balance of equity as of January 1, 2018. These ASUs require expanded qualitative and quantitative disclosures of revenue and cash flows emerging from Contracts with Customers. The Company has evaluated the provisions of the new standard and is in the process of assessing its impact on financial statements, information systems, business processes and financial statement disclosures. Based on initial reviews, the standard is not expected to have a material impact on the Company's Consolidated Financial Statements.
