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 small, medium and large 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, the terms the “Company” and “CDW” refer to Parent and its subsidiaries. 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 Statements as of June 30, 2024 and for the three and six months ended June 30, 2024 and 2023 (the “Consolidated Financial Statements”) have been prepared in conformity with accounting principles generally accepted in the United States of America (“US 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 US 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, 2023 (the “December 31, 2023 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, 2023 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 December 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This ASU enhances existing income tax disclosures primarily through standardization and disaggregation of rate reconciliation categories and income taxes paid by jurisdiction. The ASU is effective for all public entities for annual periods beginning after December 15, 2024, 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 this ASU will have on its disclosures. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. This ASU improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses included in a segment’s profit or loss measure on an annual and interim basis. The ASU is effective for all public entities for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Entities are required to apply the amendments on a retrospective basis. The Company is currently evaluating the impact this ASU will have on its disclosures.
