Accounting Policies [Abstract] |
ACCOUNTING POLICIES | Basis of Presentation The accompanying unaudited Condensed Consolidated Financial Statements of Wesco have been prepared in accordance with Rule 10-01 of Regulation S-X of the Securities and Exchange Commission (the “SEC”). The unaudited condensed consolidated financial information should be read in conjunction with the audited Consolidated Financial Statements and Notes thereto included in WESCO International, Inc.’s Annual Report on Form 10-K for the year ended December 31, 2021, as filed with the SEC on February 25, 2022. The Condensed Consolidated Balance Sheet at December 31, 2021 was derived from the audited Consolidated Financial Statements as of that date, but does not include all of the disclosures required by accounting principles generally accepted in the United States of America. The unaudited Condensed Consolidated Balance Sheet as of September 30, 2022, the unaudited Condensed Consolidated Statements of Income and Comprehensive Income and the unaudited Condensed Consolidated Statements of Stockholders' Equity for the three and nine months ended September 30, 2022, and 2021, and the unaudited Condensed Consolidated Statements of Cash Flows for the nine months ended September 30, 2022, and 2021, respectively, in the opinion of management, have been prepared on the same basis as the audited Consolidated Financial Statements and include all adjustments necessary for the fair statement of the results of the interim periods presented herein. All adjustments reflected in the unaudited condensed consolidated financial information are of a normal recurring nature unless indicated. The results for the interim periods presented herein are not necessarily indicative of the results to be expected for the full year. Recently Adopted and Recently Issued Accounting Standards In March 2020, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments in this ASU are effective for all entities as of March 12, 2020 through December 31, 2022. The Company adopted this ASU during the first quarter of 2022 in connection with amending Wesco's credit facilities, as disclosed in Note 7, "Debt". The replacement of London Interbank Offered Rate ("LIBOR") and the related adoption of the optional guidance under this accounting standard did not have a material impact on the Company's consolidated financial statements and notes thereto. In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, which requires contract assets and contract liabilities acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with ASC Topic 606, Revenue from Contracts with Customers, as if the acquirer had originated the contracts. The amendments in this ASU are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Management is currently evaluating the impact that the adoption of this accounting standard will have on its consolidated financial statements and notes thereto. In September 2022, the FASB issued ASU 2022-04, Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations, which requires that a buyer in a supplier finance program disclose sufficient information about the program to allow a user of financial statements to understand the program's nature, activity during the period, changes from period to period, and potential magnitude. The amendments in this ASU are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, except for the amendment on rollforward information, which is effective for fiscal years beginning after December 15, 2023. Early adoption is permitted. Management is currently evaluating the impact that the adoption of this accounting standard will have on its consolidated financial statements and notes thereto. Other pronouncements issued by the FASB or other authoritative accounting standards groups with future effective dates are either not applicable or are not expected to be significant to Wesco’s financial position, results of operations or cash flows.
