Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Business and Organization	Note 1. Nature of Business and Organization Nature of Business Artisan Partners Asset Management Inc. (“APAM”), through its subsidiaries, is an investment management firm focused on providing high-value added, active investment strategies to sophisticated clients globally. APAM and its subsidiaries are hereafter referred to collectively as “Artisan” or the “Company”. Artisan’s autonomous investment teams manage a broad range of U.S., non-U.S. and global investment strategies that are diversified by asset class, market cap and investment style. Strategies are offered through multiple investment vehicles to accommodate a broad range of client mandates. Artisan offers its investment management services primarily to institutions and through intermediaries that operate with institutional-like decision-making processes and have long-term investment horizons. Organization On March 12, 2013, APAM completed its initial public offering (the “IPO”). APAM was formed for the purpose of becoming the general partner of Artisan Partners Holdings LP (“Artisan Partners Holdings” or “Holdings”) in connection with the IPO. Holdings is a holding company for the investment management business conducted under the name “Artisan Partners”. The reorganization (“IPO Reorganization”) established the necessary corporate structure to complete the IPO while at the same time preserving the ability of the firm to conduct operations through Holdings and its subsidiaries. As its sole general partner, APAM controls the business and affairs of Holdings. As a result, APAM consolidates Holdings’ financial statements and records a noncontrolling interest for the equity interests in Holdings held by the limited partners of Holdings. At December 31, 2021, APAM held approximately 84% of the equity ownership interest in Holdings.

Accounting Policies [Abstract]
Summary of significant accounting policies	Note 2. Summary of Significant Accounting Policies Basis of presentation The accompanying consolidated financial statements were prepared in accordance with U.S. generally accepted accounting principles (“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 Consolidated Financial Statements. As of December 31, 2021, Artisan had a controlling financial interest in one series of Artisan Funds, three sub-funds of Artisan Global Funds and two Artisan Private Funds and, as a result, these funds are included in Artisan’s 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 6, “Variable Interest Entities and Consolidated Investment Products” for additional details. Operating segments Artisan operates in one segment, the investment management industry. Artisan provides investment management services to separate accounts and pooled investment vehicles. Management assesses the financial performance of these vehicles on a combined basis. Cash and cash equivalents Artisan defines cash and cash equivalents as money market funds and other highly liquid investments with original maturities of 90 days or less. Cash and cash equivalents are stated at cost, which approximates fair value due to the short-term nature and liquidity of these financial instruments. For disclosure purposes, cash equivalents are categorized as Level 1 in the fair value hierarchy. Cash and cash equivalents are subject to credit risk and were primarily maintained in demand deposit accounts with financial institutions or treasury money market funds. Interest and dividends related to cash and cash equivalents is recorded in other investment gain (loss) in the Consolidated Statements of Operations. Foreign currency translation Assets and liabilities of foreign operations whose functional currency is not the U.S. dollar are translated at prevailing year-end exchange rates. Revenue and expenses of such foreign operations are translated at average exchange rates during the year. The net effect of the translation adjustment for foreign operations is included in other comprehensive income (loss) in the Consolidated Statements of Comprehensive Income. The cumulative effect of translation adjustments is included in accumulated other comprehensive income (loss) and noncontrolling interests - Artisan Partners Holdings in the Consolidated Statements of Financial Condition, based on period-end ownership levels. Accounts receivable Accounts receivable are carried at invoiced amounts and consist primarily of investment advisory fees that have been earned, but not yet received from clients. Due to the short-term nature of the receivables, the carrying values of these assets approximate fair value. The accounts receivable balance does not include any allowance for doubtful accounts as Artisan believes all accounts receivable balances are fully collectible. There has not been any bad debt expense recorded for the years ended December 31, 2021, 2020 and 2019. Investment securities Investment securities consist of nonconsolidated investments in shares of Artisan Funds, Artisan Global Funds, and Artisan Private Funds. Investments provide exposure to various risks, including price risk (the risk of a potential future decline in value of the investment) and foreign currency risk. Investments are carried at fair value based on net asset values as of the valuation date. Realized and unrealized gains (losses) on nonconsolidated investment securities are recorded in other net investment gain (loss) in the Consolidated Statements of Operations. Dividend income from these investments is recognized when earned and is also included in other investment gain (loss). Property and equipment Property and equipment are carried at cost, less accumulated depreciation. Depreciation is generally recognized on a straight-line basis over the estimated useful lives of the respective assets or the remaining lease term, whichever is shorter. The estimated useful lives of property and equipment as of December 31, 2021 are as follows: Property and Equipment Type Useful Life Computers and equipment Three Computer software Three Furniture and fixtures Seven years Leasehold improvements Two Implementation costs incurred to develop or obtain internal-use software, including hosting arrangements, are capitalized and expensed on a straight-line basis over either the estimated useful life of the respective software or the term of the hosting arrangement. Property and equipment is tested for impairment when there is an indication that the carrying amount of an asset may not be recoverable. When an asset is determined to not be recoverable, the impairment loss is measured based on the excess, if any, of the carrying value of the asset over its fair value. Leases Artisan has lease commitments for office space, parking structures, and equipment, which are all accounted for as operating leases. Artisan records expense for operating leases on a straight-line basis over the lease term. Any lease incentives received by Artisan are also amortized on a straight-line basis over the lease term. Artisan assesses its contractual arrangements for the existence of a lease at inception. Operating leases with an initial term greater than 12 months are recorded as operating lease assets and operating lease liabilities in the Consolidated Statements of Financial Condition. Lease components (e.g. fixed rental payments) and non-lease components (e.g. fixed common-area maintenance costs) are generally accounted for as a single component. Operating lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. Operating lease assets are recognized at the lease commencement date based on the present value of lease payments over the lease term, adjusted for prepaid rent and the remaining balance of lease incentives received. Artisan's lease agreements generally do not provide an implicit interest rate, and therefore the present value calculation uses Artisan's estimated incremental borrowing rate. A market-based approach is used to estimate the incremental borrowing rate for each individual lease using observable market interest rates and Artisan specific inputs. The lease terms include periods covered by options to extend or exclude periods covered by options to terminate the lease when it is reasonably certain that Artisan will exercise that option. Restricted cash Restricted cash represents cash that is restricted as collateral on a standby letter of credit related to a lease obligation. Cash and cash equivalents of consolidated investment products Cash and cash equivalents of consolidated investment products consist of highly liquid investments, including money market funds. See Note 6, “Variable Interest Entities and Consolidated Investment Products” for additional details. Investment assets and liabilities of consolidated investment products Investment assets and liabilities of consolidated investment products primarily consist of equity securities, fixed income securities and options. The carrying value of the investment assets and liabilities is also their fair value. Changes in the fair value of the investments are recognized as gains and losses in earnings. Equity securities are generally valued based upon closing market prices of the security on the principal exchange on which the security is traded. Fixed income securities include corporate bonds, convertible bonds and bank loans. Fixed income securities are generally valued based on the judgment of pricing vendors. Derivative assets and liabilities are generally comprised of put and call options on securities or indices. Put and call options are valued at the mid price (average of the bid price and ask price) as provided by the pricing vendor at the close of trading on the contract’s principal exchange. See Note 6, “Variable Interest Entities and Consolidated Investment Products” for additional details. Redeemable noncontrolling interests Redeemable noncontrolling interests represent third-party investors’ ownership interest in consolidated investment products. Third-party investors in consolidated investment products generally have the right to withdraw their capital, subject to certain conditions. Noncontrolling interests of consolidated investment products that are currently redeemable or convertible for cash or other assets at the option of the holder are classified as temporary equity. Revenue recognition Artisan’s investment advisory revenue is derived from contracts with customers in the form of investment management fees and performance fees. Investment Management Fees Investment management fees are generally computed as a percentage of assets under management and are recognized as revenue at the end of each distinct service period. Management fees for providing investment advisory services are computed and billed in accordance with the underlying investment management agreements, which is generally on a monthly or quarterly basis. Investment management fees are presented net of cash rebates and expense reimbursements pursuant to contractual expense limitations of certain funds. Performance Fees A number of investment management agreements provide for performance-based fees or incentive allocations, collectively “performance fees”. Performance fees, if earned, are recognized upon completion of the contractually determined measurement period, which is generally quarterly or annually. Performance fees are not subject to claw back as a result of performance declines subsequent to the most recent measurement date. Revenue Recognition Artisan accounts for asset management services as a single performance obligation that is satisfied over time, using a time-based measure of progress to recognize revenue. Customer consideration is variable due to the uncertainty of the value of assets under management during each distinct service period. At the end of each period, Artisan records revenue for the actual amount of investment management fees earned for that period because the uncertainty has been resolved. Performance fees are subject to the uncertainty of market volatility, and as a result, the entire amount of the variable consideration related to performance fees is constrained until the end of each measurement period. At the end of the measurement period, revenue is recorded for the actual amount of performance fees earned during that period because the uncertainty has been resolved. For performance fees with annual measurement periods, revenue recognized in the current period could relate to performance obligations that were partially satisfied in prior periods. Customer Rebates and Expense Reimbursements Artisan has contractually agreed to reimburse for expenses incurred to the extent necessary to limit annualized ordinary operating expenses incurred by certain funds to not more than a fixed percentage of the funds’ average daily net assets. Artisan may also contractually agree to pay fee rebates to certain investors in Artisan Global Funds. Artisan accounts for all reimbursements and rebates as a reduction of the transaction price (and, hence, of revenue) because the billing adjustments and payments represent consideration payable to customers and Artisan does not receive any distinct goods or services from the customers in exchange. Share-based compensation Share-based compensation expense is recognized based on the estimated grant date fair value on a straight-line basis over the requisite service period of the award. The initial requisite service period is generally five years for restricted share-based awards. The Company’s accounting policy is to record the impact of forfeitures when they occur. Distribution, servicing and marketing Artisan Funds has authorized certain financial services companies, broker-dealers, banks or other intermediaries, and in some cases other organizations designated by an authorized intermediary, to accept purchase, exchange, and redemption orders for shares of Artisan Funds on the funds’ behalf. Many intermediaries charge a fee for accounting and shareholder services provided to fund shareholders on the funds’ behalf. Those services typically include recordkeeping, transaction processing for shareholders’ accounts, and other services. Fees are either based on the number of accounts to which the intermediary provides such services or a percentage of the average daily value of fund shares held in such accounts. The funds pay a portion of such fees directly to the intermediaries, which are intended to compensate the intermediary for its provision of services of the type that would be provided by the funds’ transfer agent or other service providers if the shares were registered directly on the books of the funds’ transfer agent. Artisan pays the balance of those fees which includes compensation to the intermediary for its distribution, servicing and marketing of Artisan Funds shares. Artisan Global Funds also have arrangements pursuant to which Artisan is required to pay a portion of its investment management fee for distribution, servicing and marketing of Artisan Global Funds shares. Distribution, servicing and marketing fees paid by Artisan are presented as an operating expense because Artisan is the principal in its role as the primary obligor related to these services. Expenses incurred were as follows: For the Years Ended December 31, 2021 2020 2019 Expenses incurred with respect to Artisan Funds $ 28,640 $ 21,320 $ 20,096 Expenses incurred with respect to Global Funds 899 595 424 Other marketing expenses 2,180 2,397 2,650 Total distribution, servicing and marketing $ 31,719 $ 24,312 $ 23,170 Accrued fees to intermediaries were $5.3 million and $4.2 million as of December 31, 2021 and 2020, respectively, and are included in accounts payable, accrued expenses and other in the Consolidated Statements of Financial Condition. Loss contingencies Artisan considers the assessment of loss contingencies as a significant accounting policy because of the significant uncertainty relating to the outcome of any potential legal actions and other claims and the difficulty of predicting the likelihood and range of the potential liability involved, coupled with the material impact on Artisan’s results of operations that could result from legal actions or other claims and assessments. Artisan recognizes estimated costs to defend as incurred. Potential loss contingencies are reviewed at least quarterly and are adjusted to reflect the impact and status of settlements, rulings, advice of counsel and other information pertinent to a particular matter. Significant differences could exist between the actual cost required to investigate, litigate and/or settle a claim or the ultimate outcome of a suit and management’s estimate. These differences could have a material impact on Artisan’s results of operations, financial position, or cash flows. Recoveries of losses are recognized in the Consolidated Statements of Operations when receipt is deemed probable. No loss contingencies were recorded at December 31, 2021, 2020 and 2019. Currently, there are no legal or administrative proceedings that management believes may have a material effect on Artisan’s consolidated financial position, cash flows or results of operations. Income taxes Artisan accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the future tax consequences attributable to temporary differences between the financial statement carrying amounts and tax bases of assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be realized or settled. Artisan recognizes a valuation allowance if it is more likely than not that some portion or all of the deferred tax assets will not be realized. Artisan accounts for uncertain income tax positions by recognizing the impact of a tax position in its consolidated financial statements when Artisan believes it is more likely than not that the tax position would not be sustained upon examination by the appropriate tax authorities based on the technical merits of the position. Comprehensive income (loss) Total comprehensive income (loss) includes net income and other comprehensive income. Other comprehensive income (loss) consists of foreign currency translation. Partnership distributions Artisan makes distributions to its partners for purposes of paying income taxes as required under the terms of Artisan Partners Holdings’ partnership agreement. Tax distributions are calculated utilizing the highest combined individual federal, state and local income tax rate among the various locations in which the partners, as a result of owning their interests in the partnership, are subject to tax, assuming maximum applicability of the phase-out of itemized deductions contained in the Internal Revenue Code that apply to any specific tax year. Artisan also makes additional distributions under the terms of the partnership agreement. Distributions are recorded in the financial statements on the declaration date. Earnings per share Basic earnings per share is computed under the two-class method by dividing income available to Class A common stockholders by the weighted average number of Class A common shares outstanding during the period. Unvested restricted share-based awards are excluded from the number of Class A common shares outstanding for the basic earnings per share calculation because the shares have not yet been earned by employees. Income available to Class A common stockholders is computed by reducing net income attributable to APAM by earnings (both distributed and undistributed) allocated to participating securities, according to their respective rights to participate in those earnings. Except for certain performance share units, unvested share-based awards are participating securities because the awards include non-forfeitable dividend rights during the vesting period. Class B and Class C common shares do not share in profits of APAM and therefore are not reflected in the calculations. Diluted earnings per share is computed under the more dilutive of the treasury stock method or the two-class method. The weighted average number of Class A common shares outstanding during the period is increased by the assumed conversion of nonparticipating unvested share-based awards into Class A common stock using the treasury stock method. Recent accounting pronouncements None.

Fair Value Measurements	Note 4. Fair Value Measurements The table below presents information about Artisan’s assets and liabilities that are measured at fair value and the valuation techniques Artisan utilized to determine such fair value. The financial instruments held by consolidated investment products are excluded from the table below and are presented in Note 6, “Variable Interest Entities and Consolidated Investment Products”. In accordance with ASC 820, fair value is defined as the price that Artisan would receive upon selling an investment in an orderly transaction to an independent buyer in the principal or most advantageous market for the investment. The following three-tier fair value hierarchy prioritizes the inputs used in measuring fair value: • Level 1 – Observable inputs such as quoted (unadjusted) market prices in active markets for identical securities. • Level 2 – Other significant observable inputs (including but not limited to quoted prices for similar instruments, interest rates, prepayment speeds, credit risk, etc.). • Level 3 – Significant unobservable inputs (including Artisan’s own assumptions in determining fair value). The following provides the hierarchy of inputs used to derive fair value of Artisan’s assets and liabilities that are financial instruments as of December 31, 2021 and 2020: Assets and Liabilities at Fair Value Total NAV Practical Expedient (No Fair Value Level) Level 1 Level 2 Level 3 December 31, 2021 Assets Money market funds $ 37,861 $ — $ 37,861 $ — $ — Equity securities 47,878 9,975 37,903 — — December 31, 2020 Assets Money market funds $ 25,855 $ — $ 25,855 $ — $ — Equity securities 3,656 57 3,599 — —

The inputs are categorized as Level 2 in the fair value hierarchy, as defined in Note 4, “Fair Value Measurements”. Senior notes - On December 7, 2021, Holdings entered into a Note Purchase Agreement to issue $90.0 million of Series F senior notes in a private placement transaction on August 16, 2022, subject to the satisfaction of certain customary closing conditions. The Company will use the proceeds from the Series F senior notes to repay the $90.0 million of Series C senior notes that mature on August 16, 2022. The Series F senior notes will bear interest at a rate of 3.10% and will mature on August 16, 2032. The fixed interest rate on each series of unsecured notes is subject to a one percentage point increase in the event Holdings receives a below-investment grade rating and any such increase will continue to apply until an investment grade rating is received. Revolving credit agreement - Any loans outstanding under the revolving credit agreement bear interest at a rate per annum equal to, at the Company’s election, (i) LIBOR adjusted by a statutory reserve percentage plus an applicable margin ranging from 1.50% to 2.50%, depending on Holdings’ leverage ratio (as defined in the revolving credit agreement) or (ii) an alternate base rate equal to the highest of (a) Citibank, N.A.’s prime rate, (b) the federal funds effective rate plus 0.50%, and (c) the daily one-month LIBOR adjusted by a statutory reserve percentage plus 1.00%, plus, in each case, an applicable margin ranging from 0.50% to 1.50%, depending on Holdings’ leverage ratio.

Fair Value Disclosures [Abstract]
Variable Interest Entities and Consolidated Investment Products	Note 6. Variable Interest Entities and Consolidated Investment Products Artisan serves as the investment adviser for various types of investment products, consisting of both VIEs and VOEs. Artisan consolidates an investment product if it has a controlling financial interest in the entity. See Note 2, “Summary of Significant Accounting Policies”. Any such entities are collectively referred to herein as consolidated investment products or CIPs. As of December 31, 2021, Artisan is considered to have a controlling financial interest in one series of Artisan Funds, three sub-funds of Artisan Global Funds and two Artisan Private Funds, with an aggregate direct equity investment in the consolidated investment products of $61.9 million. Artisan’s maximum exposure to loss in connection with the assets and liabilities of CIPs is limited to its direct equity investment, while the potential benefit is limited to the management and performance fees received and the return on its equity investment. With the exception of Artisan’s direct equity investment, the assets of CIPs are not available to Artisan’s creditors, nor are they available to Artisan for general corporate purposes. In addition, third-party investors in the CIPs have no recourse to the general credit of the Company. Management and performance fees earned from CIPs are eliminated from revenue upon consolidation. See Note 17, “Related Party Transactions” for additional information on management and performance fees earned from CIPs. Third-party investors’ ownership interest in CIPs is presented as redeemable noncontrolling interests in the Consolidated Statements of Financial Condition as third-party investors have the right to withdraw their capital, subject to certain conditions. Net income attributable to third-party investors is reported as net income attributable to noncontrolling interests - consolidated investment products in the Consolidated Statements of Operations. During the year ended December 31, 2021, the Company determined that it no longer had a controlling financial interest in one Artisan Private Fund upon the redemption of the Company's seed investment. Upon loss of control, the VIE was deconsolidated and the following assets, liabilities, and equity of the fund were derecognized from the Company’s Consolidated Statements of Financial Condition: As of January 1, 2021 Assets of consolidated investment products Cash and cash equivalents $ 34,823 Accounts receivable and other 1,769 Investment assets, at fair value 72,868 Less: Amounts reclassified to investment securities (11,200) Total assets $ 98,260 Liabilities of consolidated investment products Accounts payable, accrued expenses and other $ 76,960 Investment liabilities, at fair value 566 Total liabilities 77,526 Redeemable noncontrolling interests 20,734 Total liabilities and equity $ 98,260 There was no net impact to the Consolidated Statements of Operations for the year ended December 31, 2021. Artisan generally does not recognize a gain or loss upon deconsolidation of investment products because the assets and liabilities of CIPs are carried at fair value. As of December 31, 2021, Artisan held direct equity investments of $10.7 million in VIEs for which the Company does not hold a controlling financial interest. These direct equity investments consisted of seed investments in sub-funds of Artisan Global Funds and Artisan Private Funds, both of which are accounted for under the equity method of accounting because Artisan has significant influence over the funds. Fair Value Measurements - Consolidated Investment Products Investments held by CIPs are reflected at fair value. Short and long positions on equity securities are valued based upon closing prices of the security on the exchange or market designated by the accounting agent or pricing vendor as the principal exchange. The closing price may represent last sale price, official closing price, a closing auction or other information depending on market convention. Short and long positions on fixed income instruments are valued at market value. Market values are generally evaluations based on the judgment of pricing vendors, which may consider, among other factors, the prices at which securities actually trade, broker-dealer quotations, pricing formulas, estimates of market values obtained from yield data relating to investments or securities with similar characteristics and/or discounted cash flow models that might be applicable. Derivative assets and liabilities are generally comprised of put and call options on securities and indices. Put and call options are valued at the mid price (average of bid price and ask price) as provided by the pricing vendor at the close of trading on the contract’s principal exchange. The following tables present the fair value hierarchy levels of assets and liabilities held by CIPs measured at fair value as of December 31, 2021 and 2020: Assets and Liabilities at Fair Value Total Level 1 Level 2 Level 3 December 31, 2021 Assets Money market funds $ 7,908 $ 7,908 $ — $ — Equity securities - long position 33,583 31,838 1,745 — Fixed income instruments - long position 161,177 — 156,240 4,937 Derivative assets 241 — 241 — Liabilities Equity securities - short position $ 3,427 $ 3,427 $ — $ — Fixed income instruments - short position 15,570 — 15,570 — Derivative liabilities 182 4 178 — December 31, 2020 Assets Money market funds $ 7,822 $ 7,822 $ — $ — Equity securities - long position 83,960 83,027 933 — Fixed income instruments - long position 133,518 — 133,518 — Derivative assets 12,902 12,902 — — Liabilities Fixed income instruments - short position $ 14,978 $ — $ 14,978 $ — Derivative liabilities 753 566 187 — CIP balances included in the Company's consolidated statements of financial condition were as follows: As of December 31, As of December 31, Net CIP assets included in the table above $ 183,730 $ 222,471 Net CIP assets not included in the table above (10,769) (69,763) Total Net CIP assets 172,961 152,708 Less: redeemable noncontrolling interests 111,035 93,753 Artisan’s direct equity investment in CIPs $ 61,926 $ 58,955

Noncontrolling Interest [Abstract]
Noncontrolling Interest - Holdings	Note 7. Noncontrolling Interests - Holdings Net income attributable to noncontrolling interests - Artisan Partners Holdings in the Consolidated Statements of Operations represents the portion of earnings or loss attributable to the equity ownership interests in Holdings held by the limited partners of Holdings. As of December 31, 2021, APAM held approximately 84% of the equity ownership interests in Holdings. Limited partners of Artisan Partners Holdings are entitled to exchange partnership units (along with a corresponding number of shares of Class B or C common stock of APAM) for shares of Class A common stock from time to time (the "Holdings Common Unit Exchanges"). The Holdings Common Unit Exchanges increase APAM's equity ownership interest in Holdings and result in an increase to deferred tax assets and amounts payable under the tax receivable agreements. See Note 11, “Income Taxes and Related Payments”. In order to maintain the one-to-one correspondence of the number of Holdings partnership units and APAM common shares, Holdings will issue one general partner (“GP”) unit to APAM for each share of Class A common stock issued by APAM. For the years ended December 31, 2021, 2020 and 2019, APAM’s equity ownership interest in Holdings has increased as a result of the following transactions: Holdings GP Units Limited Partnership Units Total APAM Ownership % Balance at January 1, 2019 54,071,188 22,871,684 76,942,872 70 % Issuance of APAM Restricted Shares, Net (1) 876,271 — 876,271 — % Holdings Common Unit Exchanges 1,499,655 (1,499,655) — 3 % Forfeitures from Employee Terminations (1) (17,289) — (17,289) — % Balance at December 31, 2019 56,429,825 21,372,029 77,801,854 73 % Issuance of APAM Restricted Shares, Net (1) 789,114 — 789,114 — % Delivery of Shares Underlying RSUs (1) 24,233 — 24,233 — % 2020 Follow-On Offering 1,802,326 (1,802,326) — 2 % Holdings Common Unit Exchanges 4,128,600 (4,128,600) — 5 % Forfeitures from Employee Terminations (1) (43,091) — (43,091) — % Balance at December 31, 2020 63,131,007 15,441,103 78,572,110 80 % Issuance of APAM Restricted Shares, Net 562,289 — 562,289 1 % Delivery of Shares Underlying RSUs (1) 1,074 — 1,074 — % 2021 Follow-On Offering 963,614 (963,614) — 1 % Holdings Common Unit Exchanges 2,142,292 (2,142,292) — 2 % Forfeitures from Employee Terminations (1) (100,404) — (100,404) — % Balance at December 31, 2021 66,699,872 12,335,197 79,035,069 84 % (1) The impact of the transaction on APAM’s ownership percentage was less than 1%. Changes in ownership of Holdings are accounted for as equity transactions because APAM continues to have a controlling interest in Holdings. Additional paid-in capital and noncontrolling interests - Artisan Partners Holdings in the Consolidated Statements of Financial Condition are adjusted to reallocate Holdings’ historical equity to reflect the change in APAM’s ownership of Holdings. The reallocation of equity had the following impact on the Consolidated Statements of Financial Condition: Statements of Financial Condition For the Years Ended December 31, 2021 2020 Additional paid-in capital $ (563) $ (2,544) Noncontrolling interests - Artisan Partners Holdings 611 2,733 Accumulated other comprehensive income (loss) (48) (189) Net impact to financial condition $ — $ — In addition to the reallocation of historical equity, the change in ownership resulted in an increase to deferred tax assets and additional paid-in capital of $1.8 million and $4.3 million for the years ended December 31, 2021 and 2020, respectively.

As of December 31, 2021, Artisan’s employees held 5,135,864 restricted shares of Class A common stock and all 3,206,580 outstanding shares of Class B common stock, all of which were subject to the agreement. APAM is dependent on cash generated by Holdings to fund any dividends. Generally, Holdings will make distributions to all of its partners, including APAM, based on the proportionate share of ownership each has in Holdings. APAM will fund dividends to its stockholders from its proportionate share of those distributions after provision for its taxes and other obligations. APAM declared and paid the following dividends per share during the years ended December 31, 2021, 2020 and 2019: For the Years Ended December 31, Type of Dividend Class of Stock 2021 2020 2019 Quarterly Common Class A $ 3.92 $ 2.79 $ 2.36 Special Annual Common Class A $ 0.31 $ 0.60 $ 1.03 The following table summarizes APAM’s stock transactions for the years ended December 31, 2021, 2020 and 2019: Total Stock Outstanding Class A Common Stock (1) Class B Common Stock Class C Common Stock Balance at January 1, 2019 76,942,872 54,071,188 8,645,249 14,226,435 Holdings Common Unit Exchanges — 1,499,655 (841,885) (657,770) Restricted Share Award Grants 959,000 959,000 — — Restricted Share Award Net Share Settlement (82,729) (82,729) — — Employee/Partner Terminations (17,289) (17,289) — — Balance at December 31, 2019 77,801,854 56,429,825 7,803,364 13,568,665 2020 Follow-On Offering — 1,802,326 (1,777,326) (25,000) Holdings Common Unit Exchanges — 4,128,600 (1,535,275) (2,593,325) Delivery of Shares Underlying RSUs 24,233 24,233 — — Restricted Share Award Grants 916,085 916,085 — — Restricted Share Award Net Share Settlement (126,971) (126,971) — — Employee/Partner Terminations (43,091) (43,091) (32,805) 32,805 Balance at December 31, 2020 78,572,110 63,131,007 4,457,958 10,983,145 2021 Follow-On Offering — 963,614 (638,614) (325,000) Holdings Common Unit Exchanges — 2,142,292 (612,764) (1,529,528) Delivery of Shares Underlying RSUs 1,074 1,074 — — Restricted Share Award Grants 740,249 740,249 — — Restricted Share Award Net Share Settlement (177,960) (177,960) — — Employee/Partner Terminations (100,404) (100,404) — — Balance at December 31, 2021 79,035,069 66,699,872 3,206,580 9,128,617 (1) There were 327,713, 304,570, and 297,891 restricted stock units outstanding at December 31, 2021, 2020, and 2019, respectively. In addition, there were 135,230 and 60,000 performance share units outstanding at December 31, 2021 and 2020, respectively. Based on the current status of the market and performance conditions, the 135,230 unvested performance share units would ultimately result in the issuance of 135,233 shares of Class A common stock if all other vesting conditions were met. Restricted stock units and performance share units are not reflected in the table because they are not considered outstanding or issued stock. Each Class A, Class B, Class D and Class E common unit of Holdings (together with the corresponding share of Class B or Class C common stock) is exchangeable for one share of Class A common stock. The corresponding shares of Class B and Class C common stock are immediately canceled upon any such exchange. Upon termination of employment with Artisan, an employee-partner’s Class B common units are exchanged for Class E common units and the corresponding shares of Class B common stock are canceled. APAM issues the former employee-partner a number of shares of Class C common stock equal to the former employee-partner’s number of Class E common units. Class E common units are exchangeable for Class A common stock subject to the same restrictions and limitations on exchange applicable to the other common units of Holdings. Artisan Partners Holdings - Partners’ Equity Holdings makes distributions of its net income to the holders of its partnership units for income taxes as required under the terms of the partnership agreement and also makes additional distributions under the terms of the partnership agreement. The distributions are recorded in the financial statements on the declaration date, or on the payment date in lieu of a declaration date. Holdings’ partnership distributions for the years ended December 31, 2021, 2020 and 2019 were as follows: For the Years Ended December 31, 2021 2020 2019 Holdings Partnership Distributions to Limited Partners $ 93,189 $ 85,805 $ 94,842 Holdings Partnership Distributions to APAM 400,191 270,044 226,245 Total Holdings Partnership Distributions $ 493,380 $ 355,849 $ 321,087

Share-based Payment Arrangement [Abstract]
Compensation and Benefits	Note 10. Compensation and Benefits Total compensation and benefits consists of the following: For the Years Ended December 31, 2021 2020 2019 Salaries, incentive compensation and benefits (1) $ 516,931 $ 399,325 $ 358,339 Long-term cash incentive compensation expense 6,887 — — Restricted share-based award compensation expense 39,236 36,493 42,117 Long-term incentive compensation expense 46,123 36,493 42,117 Total compensation and benefits $ 563,054 $ 435,818 $ 400,456 (1) Excluding long-term incentive compensation expense. Incentive compensation Cash incentive compensation paid to members of Artisan’s investment teams and members of its distribution teams is generally based on formulas that are tied directly to revenues. The majority of this incentive compensation is earned on a quarterly basis and paid in the quarter following the quarter in which the incentive was earned with the exception of fourth quarter payments which are paid in the fourth quarter of the year. Cash incentive compensation paid to most other employees is discretionary and subjectively determined based on individual performance and Artisan’s overall results during the applicable year and is generally paid on an annual basis. Long-term incentive compensation awards consist of both APAM restricted share-based awards and long-term cash awards, which are referred to as franchise capital awards. These awards are described in more detail below. Restricted share-based awards Artisan has registered 14,000,000 shares of Class A common stock for issuance under the 2013 Omnibus Incentive Compensation Plan (the “Plan”). Pursuant to the Plan, APAM has granted a combination of restricted stock awards, restricted stock units, and performance share units (collectively referred to as “restricted share-based awards” or "awards") of Class A common stock to employees. Standard Restricted Shares. Standard restricted shares are generally subject to a pro rata five-year service vesting condition. Career Shares. Career shares are generally subject to both (i) a pro rata five-year service vesting condition and (ii) a qualifying retirement (as defined in the award agreement) condition. Franchise Shares . Like career shares, franchise shares are generally subject to both (i) a pro rata five-year service vesting condition and (ii) a qualifying retirement condition. In addition, franchise shares, which are only granted to investment team members, are subject to a Franchise Protection Clause, which provides that the number of shares that ultimately vest depends on whether certain conditions relating to client cash flows are met. If such conditions are not met, compensation cost will be reversed for any shares that do not vest. Performance Share Units (PSUs) . PSUs are generally subject to (i) a three-year service vesting condition, (ii) certain performance conditions related to the Company's adjusted operating margin and total shareholder return compared to a peer group during a three-year performance period, and (iii) for one-half of the PSUs eligible to vest at the end of the performance period, a qualifying retirement condition. The number of shares of Class A common stock that are ultimately issued in connection with each PSU award will depend upon the outcome of the performance, market and qualified retirement conditions. For the portion of a PSU award with a "performance condition" under ASC 718, expense is recognized over the service period if it is probable that the performance condition will be achieved. Compensation expense is recognized based on the estimated grant date fair value on a straight-line basis over the requisite service period of the award. The initial requisite service period is generally five years for restricted stock awards and restricted stock units, and three years for performance share units. The fair value of each award is equal to the market price of the Company's common stock on the grant date, except for performance share units with a "market condition" performance metric under ASC 718, which have a grant-date fair value based on a Monte Carlo valuation model. Unvested restricted share-based awards are subject to forfeiture. Grantees are generally entitled to dividends or dividend equivalents on unvested and vested awards. 3,881,524 shares of Class A common stock were reserved and available for issuance under the Plan as of December 31, 2021. During the year ended December 31, 2021, Artisan granted 740,249 restricted stock awards, 1,306 restricted stock units, and 75,230 performance share units of Class A common stock to employees of the Company. Total compensation expense associated with the 2021 grant is expected to be approximately $44.1 million. The following tables summarize the restricted share-based award activity for the years ended December 31, 2021, 2020 and 2019: Weighted-Average Grant Date Fair Value Restricted Stock Awards and Restricted Stock Units Unvested at January 1, 2019 $ 38.04 4,678,457 Granted 22.92 963,000 Forfeited 34.61 (17,289) Vested 39.21 (618,746) Unvested at January 1, 2020 $ 35.00 5,005,422 Granted 33.80 919,455 Forfeited 30.92 (43,091) Vested 32.59 (588,144) Unvested at January 1, 2021 $ 35.09 5,293,642 Granted 52.93 741,555 Forfeited 29.99 (101,001) Vested 31.51 (688,802) Unvested at December 31, 2021 $ 38.18 5,245,394 Weighted-Average Grant Date Fair Value Performance Share Units Unvested at January 1, 2020 $ — — Granted 52.45 60,000 Forfeited — — Vested — — Unvested at January 1, 2021 $ 52.45 60,000 Granted 68.58 75,230 Forfeited — — Vested — — Unvested at December 31, 2021 $ 61.42 135,230 Based on the current status of the market and performance conditions, the 135,230 unvested performance share units would ultimately result in the issuance of 135,233 shares of Class A common stock if all other vesting conditions were met. The aggregate vesting date fair value of awards that vested during the years ended December 31, 2021, 2020 and 2019 was approximately $35.8 million , $21.0 million, and $15.9 million, respectively. The unrecognized compensation expense for the unvested restricted stock awards and restricted stock units as of December 31, 2021 was $76.5 million with a weighted average recognition period of 3.3 years remaining. The unrecognized compensation expense for the unvested performance share units as of December 31, 2021 was $5.2 million with a weighted average recognition period of 2.8 years remaining. During the years ended December 31, 2021 and 2020, the Company withheld a total of 177,960 and 126,971 restricted shares, respectively, and paid $9.2 million and $4.5 million, respectively, as a result of net share settlements to satisfy employee tax withholding obligations. These net share settlements had the effect of shares repurchased and retired by the Company, as they reduced the number of shares outstanding.

Income Tax Disclosure [Abstract]
Income Taxes and Related Payments	Note 11. Income Taxes and Related Payments APAM is subject to U.S. federal, state and local income taxation on APAM’s allocable portion of Holdings’ income, as well as foreign income taxes payable by Holdings’ subsidiaries. Components of the provision for income taxes consist of the following: For the Years Ended December 31, Current: 2021 2020 2019 Federal $ 53,131 $ 24,116 $ 13,609 State and local 14,990 8,174 6,315 Foreign 523 515 529 Total 68,644 32,805 20,453 Deferred: Federal 32,655 27,110 22,310 State and local 5,727 880 (14,954) Total 38,382 27,990 7,356 Income tax expense $ 107,026 $ 60,795 $ 27,809 The provision for income taxes differs from the amount of income tax computed by applying the applicable U.S. statutory federal income tax rate to income before provision for income taxes as follows: For the Years Ended December 31, 2021 2020 2019 U.S. federal statutory rate 21.0 % 21.0 % 21.0 % State and local taxes, net of federal tax effect 3.5 3.1 2.8 Excess tax benefits on share-based compensation (1.4) (1.1) (0.7) Rate benefit from the flow through entity (4.1) (5.5) (6.7) Change in state tax rate — (1.1) (6.8) Unrecognized tax benefits — 0.2 0.6 Other 0.4 (0.1) 0.1 Effective tax rate 19.4 % 16.5 % 10.3 % The effective tax rate includes a rate benefit attributable to the fact that, for the years ended December 31, 2021 , 2020 and 2019, approximately 19%, 24% and 31%, respectively, of Artisan Partners Holdings’ taxable earnings were attributable to other partners and not subject to corporate-level taxes. The effective tax rate was also lower than the statutory rate due to tax deductible dividends paid on unvested restricted share-based awards and favorable tax deductions related to the vesting of restricted share-based awards. The effective tax rate was also reduced in the years ended December 31, 2020, and 2019 due to the remeasurement of existing deferred tax assets resulting from an increase in Artisan's state deferred income tax rates. In connection with the IPO, APAM entered into two tax receivable agreements (“TRAs”). The first TRA, generally provides for the payment by APAM to a private equity fund (the “Pre-H&F Corp Merger Shareholder”) or its assignees of 85% of the applicable cash savings, if any, of U.S. federal, state and local income taxes that APAM actually realizes (or is deemed to realize in certain circumstances) as a result of (i) the tax attributes of the preferred units APAM acquired in the merger of a wholly-owned subsidiary of the Pre-H&F Corp Merger Shareholder into APAM in March 2013 and (ii) tax benefits related to imputed interest. The second TRA generally provides for the payment by APAM to current or former limited partners of Holdings or their assignees of 85% of the applicable cash savings, if any, of U.S. federal, state and local income taxes that APAM actually realizes (or is deemed to realize in certain circumstances) as a result of (i) certain tax attributes of their partnership units sold to APAM or exchanged (for shares of Class A common stock, convertible preferred stock or other consideration) and that are created as a result of such sales or exchanges and payments under the TRAs and (ii) tax benefits related to imputed interest. Under both agreements, APAM generally will retain the benefit of the remaining 15% of the applicable tax savings. For purposes of the TRAs, cash savings of income taxes are calculated by comparing APAM’s actual income tax liability to the amount it would have been required to pay had it not been able to utilize any of the tax benefits subject to the TRAs, unless certain assumptions apply. The TRAs will continue in effect until all such tax benefits have been utilized or expired, unless APAM exercises its right to terminate the agreements or payments under the agreements are accelerated in the event that APAM materially breaches any of its material obligations under the agreements. The actual increase in tax basis, as well as the amount and timing of any payments under these agreements, will vary depending upon a number of factors, including the timing of sales or exchanges by the holders of limited partnership units, the price of the Class A common stock at the time of such sales or exchanges, whether such sales or exchanges are taxable, the amount and timing of the taxable income APAM generates in the future and the tax rate then applicable and the portion of APAM’s payments under the TRAs constituting imputed interest or depreciable basis or amortizable basis. Payments under the TRAs, if any, will be made pro rata among all TRA counterparties entitled to payments on an annual basis to the extent APAM has sufficient taxable income to utilize the increased depreciation and amortization charges and imputed interest deductions. Artisan expects to make one or more payments under the TRAs, to the extent they are required, prior to or within 125 days after APAM’s U.S. federal income tax return is filed for each fiscal year. Interest on the TRA payments will accrue at a rate equal to one-year LIBOR plus 100 basis points from the due date (without extension) of such tax return until such payments are made. Amounts payable under the TRAs are estimates which may be impacted by factors, including but not limited to, expected tax rates, projected taxable income, and projected ownership levels and are subject to change. Changes in the estimates of amounts payable under tax receivable agreements are recorded as non-operating income (loss) in the Consolidated Statements of Operations. The change in the Company’s deferred tax assets related to the tax benefits described above and the change in corresponding amounts payable under the TRAs for the years ended December 31, 2021 and 2020 is summarized as follows: Deferred Tax Asset - Amortizable Basis Amounts Payable Under Tax Receivable Agreements December 31, 2019 $ 408,140 $ 375,324 2020 Follow-On Offering 21,424 18,211 2020 Holdings Common Unit Exchanges 48,474 41,203 Amortization (34,686) — Payments under TRAs (1) — (26,943) Change in estimate (2) 3,602 4,673 December 31, 2020 $ 446,954 $ 412,468 2021 Follow-On Offering 16,362 13,908 2021 Holdings Common Unit Exchanges 36,069 30,659 Amortization (39,483) — Payments under TRAs (1) — (31,250) Change in estimate (9) (358) December 31, 2021 $ 459,893 $ 425,427 (1) Interest payments of $42 thousand and $60 thousand were paid in addition to these TRA payments for the years ended December 31, 2021 and 2020, respectively. (2) Included in these totals are adjustments to the deferred tax assets for changes in the state deferred enacted tax rates of $3.7 million for the year ended December 31, 2020. Net deferred tax assets comprise the following: Deferred tax assets: As of December 31, 2021 As of December 31, 2020 Amortizable basis (1) $ 459,893 $ 446,954 Other (2) 38,009 35,107 Total deferred tax assets 497,902 482,061 Less: valuation allowance (3) — — Net deferred tax assets $ 497,902 $ 482,061 (1) Represents the unamortized step-up of tax basis and other tax attributes from the merger and partnership unit sales and exchanges described above. These future tax benefits are subject to the TRA agreements. (2) Represents the net deferred tax assets associated with the merger described above and other miscellaneous deferred tax assets. These future tax benefits are not subject to the TRA agreements. (3) Artisan assessed whether the deferred tax assets would be realizable and determined based on its history of taxable income that the benefits would more likely than not be realized. Accordingly, no valuation allowance is required. Accounting standards establish a minimum threshold for recognizing, and a process for measuring, the benefits of income tax return positions in financial statements. The change in the Company’s gross unrecognized tax benefits for the years ended December 31, 2021, 2020 and 2019 is summarized as follows: For the Years Ended December 31, 2021 2020 2019 Balance at beginning of year $ 1,085 $ 1,667 $ — Additions for tax positions of prior years — 1,187 1,667 Reductions for tax positions of prior years — (613) — Tax positions related to the current year — 216 — Settlements with taxing authorities — (1,372) — Expirations of statute of limitations — — — Balance at end of year $ 1,085 $ 1,085 $ 1,667 If recognized, $1.0 million and $0.7 million of the benefits recorded as of December 31, 2021 and 2020, respectively, would favorably impact the effective tax rate in future periods. The total amount of unrecognized tax benefits is currently not expected to significantly increase or decrease within the next twelve months. The Company recognizes interest and penalties related to unrecognized tax benefits as a component of the income tax provision. Accrued interest on uncertain tax positions was $0.2 million as of December 31, 2021 and 2020, and is excluded from the unrecognized tax benefits total above. The gross unrecognized tax benefit is recorded within accounts payable, accrued expenses, and other in the Company's Consolidated Statements of Financial Condition. In the normal course of business, Artisan is subject to examination by federal and certain state, local and foreign tax regulators. As of December 31, 2021, U.S. federal income tax returns filed for the years 2018 through 2020 are open and therefore subject to examination. State, local and foreign income tax returns filed are generally subject to examination from 2017 to 2020.

The Holdings limited partnership units are anti-dilutive primarily due to the impact of public company expenses. Unvested restricted share-based awards with non-forfeitable dividend rights during the vesting period are considered participating securities and are therefore anti-dilutive. The following table summarizes the weighted-average shares outstanding that are excluded from the calculation of diluted earnings per share because their effect would have been anti-dilutive: For the Years Ended December 31, Anti-Dilutive Weighted Average Shares Outstanding 2021 2020 2019 Holdings limited partnership units 14,167,538 17,885,335 21,827,809 Unvested restricted share-based awards 5,410,221 5,313,466 5,026,357 Total 19,577,759 23,198,801 26,854,166

Benefit Plans	Note 13. Benefit Plans Artisan has a 401(k) plan and similar foreign arrangements for its non-U.S. employees, under which it provides a matching contribution on employees’ pre-tax contributions. Expenses related to Artisan’s benefits plans for the years ended December 31, 2021, 2020 and 2019 were $8.4 million, $7.8 million and $7.2 million, respectively, and are included in compensation and benefits in the Consolidated Statements of Operations. Artisan provides an opportunity for eligible employees to participate in Artisan’s financial growth and success through phantom equity awards, pursuant to the Artisan Partners Holdings LP Phantom Equity Plan. The phantom equity awards provide participants the right to receive cash payments upon vesting based on the trading price of APAM’s Class A common stock. Awards made under the Phantom Equity Plan are liability awards and are subject to vesting on a pro-rata basis over five years. Award recipients must be employed by Artisan on the vesting date in order to receive payment. Expense related to the Phantom Equity Plan for the years ended December 31, 2021, 2020 and 2019 was $1.6 million, $1.6 million and $0.9 million, respectively, and is included in compensation and benefits in the Consolidated Statements of Operations. The liability at December 31, 2021 and 2020 for the plan was $1.5 million.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2021
Accounting Policies [Abstract]
Basis of presentation	Basis of presentation The accompanying consolidated financial statements were prepared in accordance with U.S. generally accepted accounting principles (“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	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.
Operating segments	Operating segments Artisan operates in one segment, the investment management industry. Artisan provides investment management services to separate accounts and pooled investment vehicles. Management assesses the financial performance of these vehicles on a combined basis.
Cash and cash equivalents	Cash and cash equivalentsArtisan defines cash and cash equivalents as money market funds and other highly liquid investments with original maturities of 90 days or less. Cash and cash equivalents are stated at cost, which approximates fair value due to the short-term nature and liquidity of these financial instruments. For disclosure purposes, cash equivalents are categorized as Level 1 in the fair value hierarchy. Cash and cash equivalents are subject to credit risk and were primarily maintained in demand deposit accounts with financial institutions or treasury money market funds. Interest and dividends related to cash and cash equivalents is recorded in other investment gain (loss) in the Consolidated Statements of Operations.
Foreign currency translation	Foreign currency translation Assets and liabilities of foreign operations whose functional currency is not the U.S. dollar are translated at prevailing year-end exchange rates. Revenue and expenses of such foreign operations are translated at average exchange rates during the year. The net effect of the translation adjustment for foreign operations is included in other comprehensive income (loss) in the Consolidated Statements of Comprehensive Income. The cumulative effect of translation adjustments is included in accumulated other comprehensive income (loss) and noncontrolling interests - Artisan Partners Holdings in the Consolidated Statements of Financial Condition, based on period-end ownership levels.
Accounts receivable	Accounts receivable Accounts receivable are carried at invoiced amounts and consist primarily of investment advisory fees that have been earned, but not yet received from clients. Due to the short-term nature of the receivables, the carrying values of these assets approximate fair value. The accounts receivable balance does not include any allowance for doubtful accounts as Artisan believes all accounts receivable balances are fully collectible. There has not been any bad debt expense recorded for the years ended December 31, 2021, 2020 and 2019.
Investment securities	Investment securities Investment securities consist of nonconsolidated investments in shares of Artisan Funds, Artisan Global Funds, and Artisan Private Funds. Investments provide exposure to various risks, including price risk (the risk of a potential future decline in value of the investment) and foreign currency risk. Investments are carried at fair value based on net asset values as of the valuation date.
Property and equipment	Property and equipment Property and equipment are carried at cost, less accumulated depreciation. Depreciation is generally recognized on a straight-line basis over the estimated useful lives of the respective assets or the remaining lease term, whichever is shorter. The estimated useful lives of property and equipment as of December 31, 2021 are as follows: Property and Equipment Type Useful Life Computers and equipment Three Computer software Three Furniture and fixtures Seven years Leasehold improvements Two Implementation costs incurred to develop or obtain internal-use software, including hosting arrangements, are capitalized and expensed on a straight-line basis over either the estimated useful life of the respective software or the term of the hosting arrangement. Property and equipment is tested for impairment when there is an indication that the carrying amount of an asset may not be recoverable. When an asset is determined to not be recoverable, the impairment loss is measured based on the excess, if any, of the carrying value of the asset over its fair value.
Restricted cash	Restricted cash Restricted cash represents cash that is restricted as collateral on a standby letter of credit related to a lease obligation.
Cash and cash equivalents of consolidated investment products	Cash and cash equivalents of consolidated investment productsCash and cash equivalents of consolidated investment products consist of highly liquid investments, including money market funds. See Note 6, “Variable Interest Entities and Consolidated Investment Products” for additional details.
Investment assets and liabilities of consolidated investment products	Investment assets and liabilities of consolidated investment productsInvestment assets and liabilities of consolidated investment products primarily consist of equity securities, fixed income securities and options. The carrying value of the investment assets and liabilities is also their fair value. Changes in the fair value of the investments are recognized as gains and losses in earnings. Equity securities are generally valued based upon closing market prices of the security on the principal exchange on which the security is traded. Fixed income securities include corporate bonds, convertible bonds and bank loans. Fixed income securities are generally valued based on the judgment of pricing vendors. Derivative assets and liabilities are generally comprised of put and call options on securities or indices. Put and call options are valued at the mid price (average of the bid price and ask price) as provided by the pricing vendor at the close of trading on the contract’s principal exchange. See Note 6, “Variable Interest Entities and Consolidated Investment Products” for additional details.
Redeemable noncontrolling interests	Redeemable noncontrolling interests Redeemable noncontrolling interests represent third-party investors’ ownership interest in consolidated investment products. Third-party investors in consolidated investment products generally have the right to withdraw their capital, subject to certain conditions. Noncontrolling interests of consolidated investment products that are currently redeemable or convertible for cash or other assets at the option of the holder are classified as temporary equity.
Revenue recognition	Revenue recognition Artisan’s investment advisory revenue is derived from contracts with customers in the form of investment management fees and performance fees. Investment Management Fees Investment management fees are generally computed as a percentage of assets under management and are recognized as revenue at the end of each distinct service period. Management fees for providing investment advisory services are computed and billed in accordance with the underlying investment management agreements, which is generally on a monthly or quarterly basis. Investment management fees are presented net of cash rebates and expense reimbursements pursuant to contractual expense limitations of certain funds. Performance Fees A number of investment management agreements provide for performance-based fees or incentive allocations, collectively “performance fees”. Performance fees, if earned, are recognized upon completion of the contractually determined measurement period, which is generally quarterly or annually. Performance fees are not subject to claw back as a result of performance declines subsequent to the most recent measurement date. Revenue Recognition Artisan accounts for asset management services as a single performance obligation that is satisfied over time, using a time-based measure of progress to recognize revenue. Customer consideration is variable due to the uncertainty of the value of assets under management during each distinct service period. At the end of each period, Artisan records revenue for the actual amount of investment management fees earned for that period because the uncertainty has been resolved. Performance fees are subject to the uncertainty of market volatility, and as a result, the entire amount of the variable consideration related to performance fees is constrained until the end of each measurement period. At the end of the measurement period, revenue is recorded for the actual amount of performance fees earned during that period because the uncertainty has been resolved. For performance fees with annual measurement periods, revenue recognized in the current period could relate to performance obligations that were partially satisfied in prior periods. Customer Rebates and Expense Reimbursements Artisan has contractually agreed to reimburse for expenses incurred to the extent necessary to limit annualized ordinary operating expenses incurred by certain funds to not more than a fixed percentage of the funds’ average daily net assets. Artisan may also contractually agree to pay fee rebates to certain investors in Artisan Global Funds. Artisan accounts for all reimbursements and rebates as a reduction of the transaction price (and, hence, of revenue) because the billing adjustments and payments represent consideration payable to customers and Artisan does not receive any distinct goods or services from the customers in exchange.
Unit and share-based compensation	Share-based compensation Share-based compensation expense is recognized based on the estimated grant date fair value on a straight-line basis over the requisite service period of the award. The initial requisite service period is generally five years for restricted share-based awards. The Company’s accounting policy is to record the impact of forfeitures when they occur.
Distribution fees	Distribution, servicing and marketing Artisan Funds has authorized certain financial services companies, broker-dealers, banks or other intermediaries, and in some cases other organizations designated by an authorized intermediary, to accept purchase, exchange, and redemption orders for shares of Artisan Funds on the funds’ behalf. Many intermediaries charge a fee for accounting and shareholder services provided to fund shareholders on the funds’ behalf. Those services typically include recordkeeping, transaction processing for shareholders’ accounts, and other services. Fees are either based on the number of accounts to which the intermediary provides such services or a percentage of the average daily value of fund shares held in such accounts. The funds pay a portion of such fees directly to the intermediaries, which are intended to compensate the intermediary for its provision of services of the type that would be provided by the funds’ transfer agent or other service providers if the shares were registered directly on the books of the funds’ transfer agent. Artisan pays the balance of those fees which includes compensation to the intermediary for its distribution, servicing and marketing of Artisan Funds shares. Artisan Global Funds also have arrangements pursuant to which Artisan is required to pay a portion of its investment management fee for distribution, servicing and marketing of Artisan Global Funds shares. Distribution, servicing and marketing fees paid by Artisan are presented as an operating expense because Artisan is the principal in its role as the primary obligor related to these services. Expenses incurred were as follows: For the Years Ended December 31, 2021 2020 2019 Expenses incurred with respect to Artisan Funds $ 28,640 $ 21,320 $ 20,096 Expenses incurred with respect to Global Funds 899 595 424 Other marketing expenses 2,180 2,397 2,650 Total distribution, servicing and marketing $ 31,719 $ 24,312 $ 23,170 Accrued fees to intermediaries were $5.3 million and $4.2 million as of December 31, 2021 and 2020, respectively, and are included in accounts payable, accrued expenses and other in the Consolidated Statements of Financial Condition.
Leases	Leases Artisan has lease commitments for office space, parking structures, and equipment, which are all accounted for as operating leases. Artisan records expense for operating leases on a straight-line basis over the lease term. Any lease incentives received by Artisan are also amortized on a straight-line basis over the lease term. Artisan assesses its contractual arrangements for the existence of a lease at inception. Operating leases with an initial term greater than 12 months are recorded as operating lease assets and operating lease liabilities in the Consolidated Statements of Financial Condition. Lease components (e.g. fixed rental payments) and non-lease components (e.g. fixed common-area maintenance costs) are generally accounted for as a single component. Operating lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. Operating lease assets are recognized at the lease commencement date based on the present value of lease payments over the lease term, adjusted for prepaid rent and the remaining balance of lease incentives received. Artisan's lease agreements generally do not provide an implicit interest rate, and therefore the present value calculation uses Artisan's estimated incremental borrowing rate. A market-based approach is used to estimate the incremental borrowing rate for each individual lease using observable market interest rates and Artisan specific inputs. The lease terms include periods covered by options to extend or exclude periods covered by options to terminate the lease when it is reasonably certain that Artisan will exercise that option.
Loss contingencies	Loss contingencies Artisan considers the assessment of loss contingencies as a significant accounting policy because of the significant uncertainty relating to the outcome of any potential legal actions and other claims and the difficulty of predicting the likelihood and range of the potential liability involved, coupled with the material impact on Artisan’s results of operations that could result from legal actions or other claims and assessments. Artisan recognizes estimated costs to defend as incurred. Potential loss contingencies are reviewed at least quarterly and are adjusted to reflect the impact and status of settlements, rulings, advice of counsel and other information pertinent to a particular matter. Significant differences could exist between the actual cost required to investigate, litigate and/or settle a claim or the ultimate outcome of a suit and management’s estimate. These differences could have a material impact on Artisan’s results of operations, financial position, or cash flows. Recoveries of losses are recognized in the Consolidated Statements of Operations when receipt is deemed probable. No loss contingencies were recorded at December 31, 2021, 2020 and 2019. Currently, there are no legal or administrative proceedings that management believes may have a material effect on Artisan’s consolidated financial position, cash flows or results of operations.
Income taxes	Income taxes Artisan accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the future tax consequences attributable to temporary differences between the financial statement carrying amounts and tax bases of assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be realized or settled. Artisan recognizes a valuation allowance if it is more likely than not that some portion or all of the deferred tax assets will not be realized. Artisan accounts for uncertain income tax positions by recognizing the impact of a tax position in its consolidated financial statements when Artisan believes it is more likely than not that the tax position would not be sustained upon examination by the appropriate tax authorities based on the technical merits of the position.
Comprehensive income (loss)	Comprehensive income (loss) Total comprehensive income (loss) includes net income and other comprehensive income. Other comprehensive income (loss) consists of foreign currency translation.
Partnership distributions	Partnership distributions Artisan makes distributions to its partners for purposes of paying income taxes as required under the terms of Artisan Partners Holdings’ partnership agreement. Tax distributions are calculated utilizing the highest combined individual federal, state and local income tax rate among the various locations in which the partners, as a result of owning their interests in the partnership, are subject to tax, assuming maximum applicability of the phase-out of itemized deductions contained in the Internal Revenue Code that apply to any specific tax year. Artisan also makes additional distributions under the terms of the partnership agreement. Distributions are recorded in the financial statements on the declaration date.
Earnings per share	Earnings per share Basic earnings per share is computed under the two-class method by dividing income available to Class A common stockholders by the weighted average number of Class A common shares outstanding during the period. Unvested restricted share-based awards are excluded from the number of Class A common shares outstanding for the basic earnings per share calculation because the shares have not yet been earned by employees. Income available to Class A common stockholders is computed by reducing net income attributable to APAM by earnings (both distributed and undistributed) allocated to participating securities, according to their respective rights to participate in those earnings. Except for certain performance share units, unvested share-based awards are participating securities because the awards include non-forfeitable dividend rights during the vesting period. Class B and Class C common shares do not share in profits of APAM and therefore are not reflected in the calculations. Diluted earnings per share is computed under the more dilutive of the treasury stock method or the two-class method. The weighted average number of Class A common shares outstanding during the period is increased by the assumed conversion of nonparticipating unvested share-based awards into Class A common stock using the treasury stock method.
Recent accounting pronouncements	Recent accounting pronouncements None.
