Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2. Summary of Significant Accounting Policies Basis of presentation The accompanying financial statements are unaudited. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of such consolidated financial statements have been included. Such interim results are not necessarily indicative of full year results. The consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial reporting and accordingly they do not include all of the information and footnotes required in the annual consolidated financial statements and accompanying footnotes. The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by U.S. GAAP. As a result, the interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in APAM’s latest annual report on Form 10-K. The accompanying financial statements were prepared in accordance with U.S. GAAP and related rules and regulations of the SEC. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates or assumptions that affect the reported amounts and disclosures in the financial statements. Actual results could differ from these estimates or assumptions. Principles of consolidation Artisan’s policy is to consolidate all subsidiaries or other entities in which it has a controlling financial interest. The consolidation guidance requires an analysis to determine if an entity should be evaluated for consolidation using the voting interest entity (“VOE”) model or the variable interest entity (“VIE”) model. Under the VOE model, controlling financial interest is generally defined as a majority ownership of voting interests. Under the VIE model, controlling financial interest is defined as (i) the power to direct activities that most significantly impact the economic performance of the entity and (ii) the right to receive potentially significant benefits or the obligation to absorb potentially significant losses. Artisan generally consolidates VIEs in which it meets the power criteria and holds an equity ownership interest of greater than 10%. The consolidated financial statements include the accounts of APAM and all subsidiaries or other entities in which APAM has a direct or indirect controlling financial interest. All material intercompany balances have been eliminated in consolidation. Artisan serves as the investment adviser to Artisan Funds, Artisan Global Funds and Artisan Private Funds. Artisan Funds and Artisan Global Funds are corporate entities, the business and affairs of which are managed by their respective boards of directors. The shareholders of the funds retain voting rights, including rights to elect and reelect members of their respective boards of directors. Each series of Artisan Funds is a VOE and is separately evaluated for consolidation under the VOE model. The shareholders of Artisan Global Funds lack simple majority liquidation rights, and as a result, each sub-fund of Artisan Global Funds is evaluated for consolidation under the VIE model. Artisan Private Funds are also evaluated for consolidation under the VIE model because third-party equity holders of the funds generally lack the ability to divest Artisan of its control of the funds. From time to time, the Company makes investments in Artisan Funds, Artisan Global Funds and Artisan Private Funds. If the investment results in a controlling financial interest, APAM consolidates the fund and the underlying activity of the entire fund is included in Artisan’s unaudited consolidated financial statements. As of June 30, 2026, Artisan had a controlling financial interest in four sub-funds of Artisan Global Funds, three Artisan Private Funds and one series of Artisan Funds and, as a result, these funds are included in Artisan’s unaudited consolidated financial statements. Because these consolidated investment products meet the definition of investment companies under U.S. GAAP, Artisan has retained the specialized industry accounting principles for investment companies in the consolidated financial statements. See Note 7, “Variable Interest Entities and Consolidated Investment Products” for additional details. Reclassification In conjunction with quarterly reporting on Form 10-Q for the quarter ended June 30, 2026, the Company added the line Gain (loss) on non-operating liabilities in the non-operating section of the unaudited consolidated statements of operations. That line will include the change in fair value of contingent consideration as well as the net gain (loss) on tax receivable agreements which was previously reported in its own line item. Amounts for the comparative prior fiscal year periods have been reclassified to conform to the current year presentation. These reclassifications had no impact on previously reported operating income, non-operating income, net income or financial position. 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,” which removes all references to software development project stages so that the guidance is neutral to different software development methods. The amendment eliminates the project stage model and clarifies that capitalization of internal-use software costs commences when management has authorized and committed funding for the project and it is probable that software will be completed and used to perform the function intended. The Company is required to adopt the guidance for the year ending December 31, 2028. The Company is currently evaluating the impact of the ASU on its consolidated financial statements. In November 2024, the FASB issued ASU 2024-03, “Disaggregation of Income Statement Expenses”, which requires disclosure of additional information and disaggregation of certain expenses included in the income statement. The Company is required to adopt the guidance for the year ending December 31, 2027. The Company is currently evaluating the impact of this ASU on its consolidated financial statements.
