Accounting Policies [Abstract] |
Basis of Presentation | 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, 2022, as filed with the SEC on February 21, 2023. The Condensed Consolidated Balance Sheet at December 31, 2022 was derived from the audited Consolidated Financial Statements as of that date, but does not include all the disclosures required by accounting principles generally accepted in the United States of America. The unaudited Condensed Consolidated Balance Sheet as of September 30, 2023, the unaudited Condensed Consolidated Statements of Income and Comprehensive Income, the unaudited Condensed Consolidated Statements of Stockholders' Equity for the three and nine months ended September 30, 2023 and 2022, and the unaudited Condensed Consolidated Statements of Cash Flows for the nine months ended September 30, 2023 and 2022, 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.
Supplier Finance Program | Supplier Finance Programs The Company has supplier finance programs that are administered by intermediaries. Under these arrangements, participating suppliers may elect to receive early payment of invoices that have been confirmed by the Company, less an interest deduction or fees paid by the supplier, which is paid to the supplier by third-party finance providers. Wesco agrees to pay the stated amount of confirmed invoices in full on the original due date of the invoices, which is typically within 45 to 180 days of the invoice date, regardless of whether the supplier elects to receive early payment from the third-party finance providers. The Company does not provide assets pledged as security or other forms of guarantees to the finance providers or intermediaries under these arrangements. As of September 30, 2023 and December 31, 2022, the amounts due to suppliers that participate in the Company's supplier finance program were approximately $37.4 million and $30.7 million, respectively, which are included in accounts payable in the Condensed Consolidated Balance Sheet.
New Accounting Pronouncements and Changes in Accounting Principles [Text Block] | Recently Adopted and Recently Issued Accounting Standards In September 2022, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“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. The Company adopted this ASU in the first quarter of 2023, except for the amendment on rollforward information, which the Company will begin disclosing in its Annual Report on Form 10-K for the fiscal year ending December 31, 2024. The adoption of this ASU resulted in additional disclosure of the Company's supplier finance program, as described below. 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.
