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, 2023, as filed with the SEC on February 20, 2024. The Condensed Consolidated Balance Sheet at December 31, 2023 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 June 30, 2024, the unaudited Condensed Consolidated Statements of Income and Comprehensive Income, the unaudited Condensed Consolidated Statements of Stockholders’ Equity for the three and six months ended June 30, 2024 and 2023, and the unaudited Condensed Consolidated Statements of Cash Flows for the six months ended June 30, 2024 and 2023, 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 June 30, 2024 and December 31, 2023, the amounts due to suppliers that participate in the Company’s supplier finance programs were approximately $27.9 million and $32.6 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 and Disclosure Rules 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 year ending December 31, 2024. The adoption of this ASU resulted in additional disclosure of the Company's supplier finance programs, as described above. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which enhances prior reportable segment disclosure requirements in part by requiring entities to disclose significant expenses related to their reportable segments. The amendments in this ASU are effective on a retrospective basis for annual periods beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. Management is currently evaluating the impact that this accounting standard will have on its consolidated financial statements and notes thereto. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires disaggregated information about a reporting entity's effective tax rate reconciliation as well as information on income taxes paid to enhance the transparency and decision usefulness of income tax disclosures. The amendments in this ASU are effective for annual periods beginning after December 15, 2024 on a prospective basis. Management is currently evaluating the impact that this accounting standard will have on its consolidated financial statements and notes thereto. In March 2024, the SEC issued final climate-related disclosure rules requiring disclosure of material climate-related risks, board and management governance of such risks, and material direct and indirect greenhouse gas emissions. The rules also require disclosure in the notes to the financial statements of the effects of severe weather events and other natural conditions. Disclosures will be made prospectively, with phased-in effective dates starting with fiscal years beginning on or after January 1, 2025. In April 2024, the SEC voluntarily stayed implementation of the climate-related disclosure rules, pending completion of judicial review of consolidated challenges to the rules by the Court of Appeals for the Eighth Circuit. Management is currently evaluating the impact that these rules could 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.
