Accounting Policies [Abstract] |
Description of Business | Description of Business CDW Corporation (“Parent”), a Fortune 500 company and member of the S&P 500 Index, is a leading multi-brand provider of information technology (“IT”) solutions to business, government, education, and healthcare customers in the United States (“US”), the United Kingdom (“UK”), and Canada. The Company’s broad array of offerings ranges from discrete hardware and software products to integrated IT solutions and services that include on-premise and cloud capabilities across hybrid infrastructure, digital experience, and security. Throughout this report, each of the terms the “Company” and “CDW” refer to Parent and its subsidiaries, collectively. Parent has two 100% owned subsidiaries, CDW LLC and CDW Finance Corporation. CDW LLC is an Illinois limited liability company that, together with its 100% owned subsidiaries, holds all material assets and conducts all business activities and operations of the Company. CDW Finance Corporation is a Delaware corporation formed for the sole purpose of acting as co-issuer of certain debt obligations and does not hold any material assets or engage in any business activities or operations.
Basis of Presentation | Basis of Presentation The accompanying unaudited interim Consolidated Financial Statem ents as of March 31, 2026, and for the three months ended March 31, 2026 and 2025 (the “Consolidated Financial Statements”) have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and the rules and regulations of the US Securities and Exchange Commission (the “SEC”) for interim financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC. The presentation of the Consolidated Financial Statements requires the Company to make estimates and assumptions that affect reported amounts and related disclosures. In the opinion of management, the Consolidated Financial Statements contain all adjustments (consisting of a normal, recurring nature) necessary to present fairly the Company’s financial position, results of operations, comprehensive income, cash flows, and changes in stockholders’ equity as of the dates and for the periods indicated. The unaudited results of operations for such interim periods reported are not necessarily indicative of results for the full year. These Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025 (the “December 31, 2025 Consolidated Financial Statements”). The significant accounting policies and estimates used in preparing these Consolidated Financial Statements were applied on a basis consistent with those reflected in the December 31, 2025 Consolidated Financial Statements.
Principles of Consolidation | Principles of Consolidation The Consolidated Financial Statements include the accounts of Parent and its 100% owned subsidiaries. All intercompany transactions and accounts are eliminated in consolidation.
Recent Accounting Pronouncements | Recent Accounting Pronouncements In September 2025, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. This ASU removes stage-based capitalization rules for internal-use software to increase the operability of the recognition guidance considering different methods of software development. The ASU is effective for all entities for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods, with early adoption permitted. Entities may apply the guidance using a prospective, modified, or retrospective transition approach. The Company is currently evaluating the impact the ASU will have on its Consolidated Financial Statements and related disclosures. In July 2025, the FASB issued ASU 2025-05, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets. This ASU provides a practical expedient to simplify the estimation of expected credit losses for current accounts receivable and current contract assets that arise from transactions accounted for under Topic 606, Revenue from Contracts with Customers. The ASU is effective for annual periods, including interim reporting periods, beginning after December 15, 2025, with early adoption permitted. Entities that elect the practical expedient should apply the amendments in this ASU on a prospective basis. The Company adopted this ASU on January 1, 2026, and elected to apply the practical expedient, which did not have any impact on its Consolidated Financial Statements and related disclosures. In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-240). This ASU requires entities to disclose disaggregated information about specific natural expense categories in the notes to the financial statements. The ASU is effective for all public entities for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027, with early adoption permitted. Entities should apply the amendments on a prospective basis, but retrospective application is permitted. The Company is currently evaluating the impact the ASU will have on its disclosures.
