Organization, Consolidation and Presentation of Financial Statements [Abstract] |
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES W.W. Grainger, Inc. is a broad line, business-to-business distributor of maintenance, repair and operating (MRO) products and services with operations primarily in North America (N.A.), Japan and the United Kingdom (U.K.). In this report, the words “Grainger” or “Company” mean W.W. Grainger, Inc. and its subsidiaries, except where the context makes it clear that the reference is only to W.W. Grainger, Inc. itself and not its subsidiaries. Basis of Presentation The Company's Condensed Consolidated Financial Statements have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial reporting and the rules and regulations of the U.S. Securities and Exchange Commission (SEC) and therefore do not include all information and disclosures normally included in the annual Consolidated Financial Statements. The preparation of these Condensed Consolidated Financial Statements and accompanying notes in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported. Actual results could differ materially from these estimated amounts. In the opinion of the Company’s management, the Condensed Consolidated Financial Statements reflect all adjustments, which are normal and recurring in nature, necessary for fair financial statement presentation. The Condensed Consolidated Balance Sheet at December 31, 2021, has been derived from the audited Consolidated Financial Statements at that date but does not include all of the information and footnotes required by GAAP for complete financial statements. The Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and accompanying notes for the year ended December 31, 2021 included in the Company’s Annual Report on Form 10-K filed with the SEC on February 23, 2022 (2021 Form 10-K). There w ere no mater ial changes to the Company’s significant accounting policies from those disclosed in Note 1 of the Notes to Consolidated Financial Statements in Part II, Item 8: Financial Statements and Supplementary Data in the Company's 2021 Form 10-K. New Accounting Standards Accounting Pronouncements Recently Adopted In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting as modified by subsequently issued ASU 2021-01. This update provides optional expedients and exceptions for applying GAAP to certain contract modifications and hedging relationships that reference London Inter-bank Offered Rate (LIBOR) or another reference rate expected to be discontinued. The guidance is effective upon issuance and generally can be applied prospectively to contract modifications made and hedging relationships entered or evaluated on or before December 31, 20 22. In October 2022, the FASB amended Topic 848, updating the sunset date from December 31, 2022 to December 31, 2024. Th e Company adopted this ASU on July 1, 2022 on a prospective basis and it did not have a material impact on the Consolidated Financial Statements. For further discussion on the credit agreement modifications made to the revolving credit facility, see Note 5. In November 2021, the FASB issued ASU 2021-10, Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance. This update provides increased transparency of government assistance, including the disclosure of the types of assistance an entity receives, an entity's method of accounting for government assistance and the effect of the assistance on an entity's financial statements. The guidance is effective for annual periods beginning after December 15, 2021 and should be applied prospectively or retrospectively. Early adoption is permitted. The Company adopted this ASU on January 1, 2022 on a prospective basis and it did not have a material impact on the Consolidated Financial Stateme nts and related disclosures.
