Organization and Description of Business	Basis of Presentation Cohen & Steers, Inc. (CNS) was organized as a Delaware corporation on March 17, 2004. CNS is the holding company for its direct and indirect subsidiaries, including Cohen & Steers Capital Management, Inc. (CSCM), Cohen & Steers Securities, LLC (CSS), Cohen & Steers UK Limited (CSUK), Cohen & Steers Ireland Limited (CSIL), Cohen & Steers Asia Limited (CSAL), Cohen & Steers Japan Limited (CSJL) and Cohen & Steers Singapore Private Limited (CSSG) (collectively, the Company).

Actual results could differ from those estimates.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Recently Adopted Accounting Pronouncements —In June 2022, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update 2022-03 (ASU), Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions . The standard clarifies that contractual sale restrictions are not considered in measuring the fair value of equity securities, which would be a change in practice for certain entities. The ASU also indicates that a contractual sale restriction is not a separate unit of account, and requires new disclosures for all entities with equity securities subject to a contractual sale restriction. This new guidance became effective on January 1, 2024. The Company's adoption of this new standard did not have an impact on the Company's consolidated financial statements. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures . The standard requires enhanced disclosure of reportable segments and additional information about a segment’s expenses. This new guidance became effective on January 1, 2024. The Company's adoption of this standard did not have a material impact on the Company's consolidated financial statements. Refer to Note 18 for further discussion. New Accounting Pronouncements Not Yet Implemented —In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures . The standard requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as additional information on income taxes paid. The standard is intended to benefit investors by providing more detailed income tax disclosures that would be useful in making capital allocation decisions. This new guidance became effective on January 1, 2025. The Company does not expect that the adoption of this new standard will have a material effect on the Company's consolidated financial statements and related disclosures. In March 2024, the FASB issued ASU 2024-01, Compensation-Stock Compensation (Topic 718): Scope Application of Profits Interest and Similar Awards . The standard clarifies how an entity determines whether a profits interest or similar award is (1) within the scope of Topic 718 or (2) not a share-based payment arrangement and therefore within the scope of other guidance. The guidance in ASU 2024-01 applies to all entities that issue profits interest awards as compensation to employees or nonemployees in exchange for goods or services. This new guidance became effective on January 1, 2025. The Company does not expect that the adoption of this new standard will have a material effect on the Company's consolidated financial statements and related disclosures. In November 2024, the FASB issued ASU 2024-03, Income Statement — Reporting Comprehensive Income — Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses . The standard requires disaggregation of certain expense captions into specified categories in disclosures within the footnotes to the financial statements. This new guidance will be effective on January 1, 2027 for annual reporting and January 1, 2028 for interim reporting. The Company is currently evaluating the impact that the adoption of this new standard will have on the Company's consolidated financial statements and related disclosures. Consolidation of Investment Vehicles —The Company's financial interests in investment vehicles, including the management fees that are received, are evaluated at inception and thereafter, if there is a reconsideration event, in order to determine whether to apply the Variable Interest Entity (VIE) model or the Voting Interest Entity (VOE) model. A VIE is an entity in which either the equity investment at risk is not sufficient to permit the entity to finance its own activities without additional financial support or the group of holders of the equity investment at risk lack certain characteristics of a controlling financial interest. The primary beneficiary is the entity that has the power to direct the activities of the VIE that most significantly affect its performance, and the obligation to absorb losses of the entity or the right to receive benefits from the entity that could potentially be significant to the VIE. Subscriptions and redemptions or amendments to the governing documents of the respective entities could affect an entity's status as a VIE or the determination of the primary beneficiary. Limited partnerships and similar entities are determined to be a VIE generally when the Company is the general partner and the limited partners do not hold substantive kick-out or participation rights. The Company assesses whether it is the primary beneficiary of any VIEs identified by evaluating its economic interests in the entity held either directly by the Company and its affiliates or indirectly through employees. VIEs for which the Company is deemed to be the primary beneficiary are consolidated. Investments that are determined to be VOEs are consolidated when the Company’s ownership interest is greater than 50% of the outstanding voting interests of the vehicle. The Company records noncontrolling interests in consolidated funds for which the Company’s ownership is less than 100%. Cash and Cash Equivalents —Cash and cash equivalents include short-term, highly liquid investments, which are readily convertible into cash. Due from/to Brokers —The Company, including the consolidated funds, may transact with brokers for certain investment activities. The clearing and custody operations for these investment activities are performed pursuant to contractual agreements. The due from/to brokers balances represent cash and/or collateral balances at brokers/custodians and/or receivables and payables for unsettled securities transactions with brokers/custodians. Investments —Management of the Company determines the appropriate classification of its investments at the time of purchase and re-evaluates such determination no less than quarterly. The Company's investments are categorized as follows: • Equity investments at fair value generally represent common stocks, limited partnership interests, exchange-traded preferred securities, and seed investments in Company-sponsored vehicles including its Non-Traded REIT. • Trading investments generally represent U.S. Treasury securities, over-the-counter preferred securities and investment-grade corporate debt securities. The Company has elected the fair value option for a seed investment that otherwise would have been accounted for using the equity method of accounting. Distributions from this seed investment are recorded in interest and dividend income—net in the Company's consolidated statements of operations when earned. Gains and losses on the Company's investments, including those for which the fair value option has been elected, are recorded in gain (loss) from investments—net in the Company's consolidated statements of operations. From time to time, the Company, including the consolidated funds, may enter into forward foreign exchange contracts to economically hedge currency exposure, and derivative contracts, including options, futures and swaps contracts, to gain exposure to the underlying commodities markets or to economically hedge market risk of the underlying portfolios. Leases —The Company determines if an arrangement is a lease at inception. The Company has operating leases for corporate offices and certain information technology equipment which are included in operating lease right-of-use (ROU) assets and operating lease liabilities on the Company’s consolidated statements of financial condition. ROU assets represent the right to use an underlying asset for the lease term and lease liabilities represent obligations to make lease payments arising from the lease. Operating lease ROU assets and lease liabilities are recognized at commencement date based on the net present value of lease payments over the life of the lease and thereafter, are remeasured if there is a change in lease terms. The majority of the Company’s lease agreements do not provide an implicit rate. As a result, the Company uses an estimated incremental borrowing rate based on the information available as of the applicable lease commencement date in determining the present value of lease payments. The operating lease ROU assets reflect any upfront lease payments made as well as lease incentives received. The lease terms may include options to extend or terminate the lease and these are factored into the determination of the ROU asset and lease liability at lease inception when and if it is reasonably certain that the Company will exercise that option. Lease expense for fixed lease payments is recognized on a straight-line basis over the lease term. The Company has certain lease agreements with non-lease components such as maintenance and executory costs, which are accounted for separately and not included in ROU assets. ROU assets are tested for impairment whenever changes in facts or circumstances indicate that the carrying amount of an asset may not be recoverable. Modification of a lease term would result in remeasurement of the lease liability and a corresponding adjustment to the ROU asset. Noncontrolling Interests —Noncontrolling interests consist of nonredeemable and redeemable third-party interests in the Company's consolidated funds. Noncontrolling interests that are not redeemable at the option of the investors are classified as nonredeemable noncontrolling interests and are included in stockholders’ equity. Noncontrolling interests that are redeemable at the option of the investors are classified as redeemable noncontrolling interests and are not treated as permanent equity. Noncontrolling interests are recorded at fair value which approximates the net asset value at each reporting date. Investment Advisory and Administration Fees —The Company earns revenue by providing asset management services to institutional accounts, open-end and closed-end funds as well as model-based portfolios. Investment advisory fees are earned pursuant to the terms of investment management agreements and are generally based on a contractual fee rate applied to the average assets under management. The Company also earns administration fees from certain open-end and closed-end funds pursuant to the terms of underlying administration contracts. Administration fees are based on the average daily assets under management of such funds. Investment advisory and administration fee revenue is recognized when earned and is recorded net of any fund reimbursements. The investment advisory and administration contracts each include a single performance obligation as the services provided are not separately identifiable and are accounted for as a series satisfied over time using a time-based method (days elapsed). Additionally, investment advisory and administration fees represent variable consideration, as fees are based on average assets under management which fluctuate daily. In certain instances, the Company may earn performance fees when specified performance hurdles are met during the performance period. Performance fees are forms of variable consideration and are not recognized until it becomes probable that there will not be a significant reversal of the cumulative revenue recognized . Distribution and Service Fee Revenue —Distribution and service fee revenue is based on the average daily net assets of certain share classes of U.S. open-end funds. Distribution and service fee revenue is earned daily and is recorded gross of any third-party distribution and service fee expense for applicable share classes. Distribution fee agreements include a single performance obligation that is satisfied at a point in time when an investor purchases shares of an open-end fund. For all periods presented, a portion of the distribution fee revenue recognized in the period may relate to performance obligations satisfied (or partially satisfied) in prior periods. Service fee agreements include a single performance obligation as the services provided are not separately identifiable and are accounted for as a series satisfied over time using a time-based method (days elapsed). Additionally, distribution and service fees represent variable consideration, as fees are based on average assets under management which fluctuate daily. Distribution and Service Fee Expense —Distribution and service fee expense includes distribution fees, shareholder servicing fees and intermediary assistance payments. Distribution fees represent payments made to qualified intermediaries for assistance in connection with the distribution of certain open-end funds' shares and for other expenses such as advertising, printing and distribution of prospectuses to investors. Such amounts may also be used to pay financial intermediaries for services as specified in the terms of written agreements complying with Rule 12b-1 of the Investment Company Act of 1940. Distribution fees are based on average daily net assets under management of certain share classes of certain of the funds. Shareholder servicing fees represent payments made to qualified intermediaries for shareholder account service and maintenance. These services are provided pursuant to written agreements with such qualified institutions. Shareholder servicing fees are generally based on average daily net assets under management. Intermediary assistance payments represent payments to qualified intermediaries for activities related to distribution, shareholder servicing as well as marketing and support of certain open-end funds and are incremental to those described above. Intermediary assistance payments are generally based on average daily net assets under management. Stock-based Compensation —The Company recognizes compensation expense for the grant-date fair value of restricted stock unit awards to certain employees. This expense is recognized over the period during which employees are required to provide service. Forfeitures are recorded as incurred. Any change to the key terms of an employee’s award subsequent to the grant date is evaluated and, if necessary, accounted for as a modification. If the modification results in the remeasurement of the fair value of the award, the remeasured compensation cost is recognized over the remaining service period. Income Taxes —The Company records the current and deferred tax consequences of all transactions that have been recognized in the consolidated financial statements in accordance with the provisions of the enacted tax laws. Deferred tax assets are recognized for temporary differences that will result in deductible amounts in future years at tax rates that are expected to apply in those years. The Company records a valuation allowance, when necessary, to reduce deferred tax assets to an amount that more likely than not will be realized. Deferred tax liabilities are recognized for temporary differences that will result in taxable income in future years at tax rates that are expected to apply in those years. The calculation of tax liabilities involves uncertainties in the application of complex tax laws and regulations across the Company's global operations. A tax benefit from an uncertain tax position is recognized when it is more likely than not that the position will be sustained upon examination, including resolution of any related appeals or litigation processes, on the basis of the technical merits. The Company records potential interest and penalties related to uncertain tax positions in the provision for income taxes in the consolidated statements of operations. Earnings Per Share —Basic earnings per share is calculated by dividing net income attributable to common stockholders by the weighted average shares outstanding. Diluted earnings per share is calculated by dividing net income attributable to common stockholders by the total weighted average shares of common stock outstanding and common stock equivalents determined using the treasury stock method. Common stock equivalents are comprised of dilutive potential shares from restricted stock unit awards and are excluded from the computation if their effect is anti-dilutive. Currency Translation and Transactions —Assets and liabilities of subsidiaries having non-U.S. dollar functional currencies are translated at exchange rates at the applicable consolidated statement of financial condition date. Revenue and expenses of such subsidiaries are translated at average exchange rates during the period. The gains or losses resulting from translating non-U.S. dollar functional currency into U.S. dollars are included in the Company's consolidated statements of comprehensive income. The cumulative translation adjustment was $(10.0) million, $(7.7) million and $(10.8) million as of December 31, 2024, 2023 and 2022, respectively, and was reported within accumulated other comprehensive income (loss) on the consolidated statements of financial condition. Gains or losses resulting from transactions denominated in currencies other than the functional currency of each respective entity and gains and losses arising on remeasurement of U.S. dollar-denominated assets and liabilities held by certain foreign subsidiaries are included in foreign currency gain (loss)—net in the Company’s consolidated statements of operations.

Fair Value Disclosures [Abstract]
Fair Value	Fair Value ASC Topic 820, Fair Value Measurement specifies a hierarchy of valuation classifications based on whether the inputs to the valuation techniques used in each valuation classification are observable or unobservable. These classifications are summarized in three broad levels: • Level 1—Unadjusted quoted prices for identical instruments in active markets. • Level 2—Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable. • Level 3—Valuations derived from valuation techniques in which significant inputs or significant value drivers are unobservable. These levels are not necessarily an indication of the risk or liquidity associated with the investments. The following tables present fair value measurements: December 31, 2024 (in thousands) Level 1 Level 2 Level 3 Investments Total Cash equivalents $ 147,832 $ — $ — $ — $ 147,832 Equity investments at fair value: Common stocks $ 96,081 $ 1,462 $ — $ — $ 97,543 Limited partnership interests — — 32,552 1,448 34,000 Preferred securities 1,507 74 — — 1,581 Non-Traded REIT — 69,998 — — 69,998 Other 5,156 — — 133 5,289 Total $ 102,744 $ 71,534 $ 32,552 $ 1,581 $ 208,411 Trading investments: Fixed income $ — $ 126,953 $ — $ — $ 126,953 Equity method investments $ — $ — $ — $ 13 $ 13 Total investments $ 102,744 $ 198,487 $ 32,552 $ 1,594 $ 335,377 Derivatives - assets: Total return swaps $ — $ 1,570 $ — $ — $ 1,570 Forward contracts - foreign exchange — 484 — — 484 Total $ — $ 2,054 $ — $ — $ 2,054 Derivatives - liabilities: Total return swaps $ — $ 252 $ — $ — $ 252 Total $ — $ 252 $ — $ — $ 252 December 31, 2023 (in thousands) Level 1 Level 2 Level 3 Investments Total Cash equivalents $ 151,915 $ — $ — $ — $ 151,915 Equity investments at fair value: Common stocks $ 163,365 $ 697 $ — $ — $ 164,062 Limited partnership interests — — 13,202 1,228 14,430 Preferred securities 1,775 62 — — 1,837 Other 508 — — 121 629 Total $ 165,648 $ 759 $ 13,202 $ 1,349 $ 180,958 Trading investments: Fixed income $ — $ 77,996 $ — $ — $ 77,996 Equity method investments $ — $ — $ — $ 16 $ 16 Total investments $ 165,648 $ 78,755 $ 13,202 $ 1,365 $ 258,970 Derivatives - assets: Total return swaps $ — $ 28 $ — $ — $ 28 Total $ — $ 28 $ — $ — $ 28 Derivatives - liabilities: Total return swaps $ — $ 2,488 $ — $ — $ 2,488 Forward contracts - foreign exchange — 405 — — 405 Total $ — $ 2,893 $ — $ — $ 2,893 Equity investments at fair value classified as Level 2 included common stocks, Cohen & Steers Income Opportunities REIT, Inc. (CNSREIT) and exchange-traded preferred securities, for which quoted prices in active markets are not available. Effective January 1, 2024, the Company deconsolidated CNSREIT and elected the fair value option to align the measurement of the seed investment and the related gains and losses with other seed investments. The Company's ownership interest was 49.4% at December 31, 2024. The fair value of this seed investment is based on the monthly published net asset value (NAV), which is an observable transaction price, however, shares are not actively traded as subscription and redemption activity happens monthly. The unrealized gain on the seed investment in CNSREIT was $2.8 million for the year ended December 31, 2024. Equity investments at fair value classified as Level 3 were comprised of limited partnership interests in joint ventures that hold investments in private real estate. Trading investments classified as Level 2 were comprised of U.S. Treasury securities, over-the-counter preferred securities and investment-grade corporate debt securities. Fair values were generally determined using third-party pricing services. The pricing services may utilize evaluated pricing models that vary by asset class and incorporate available trade, bid and other market information. Investments measured at NAV were comprised of certain investments measured at fair value using NAV (or its equivalent) as a practical expedient including limited partnership interests in private real estate funds. At December 31, 2024 and 2023, the Company did not have the ability to redeem its interests in the majority of these investments. Investments measured at NAV as a practical expedient have not been classified in the fair value hierarchy. The amounts presented in the above tables are intended to permit reconciliation of the fair value hierarchy to the amounts presented on the consolidated statements of financial condition. Total return swap contracts classified as Level 2 were valued based on the underlying futures contracts or equity indices. Foreign currency exchange contracts classified as Level 2 were valued based on the prevailing forward exchange rate, which is an input that is observable in active markets. The following table summarizes the changes in Level 3 investments measured at fair value on a recurring basis: Years Ended December 31, (in thousands) 2024 2023 Balance at beginning of period $ 13,202 $ 10,759 Purchases/contributions 19,998 11,856 Sales/distributions — (5,352) Unrealized gains (losses) (648) (4,061) Balance at end of period $ 32,552 $ 13,202 Valuation Techniques In certain instances, debt and equity securities are valued on the basis of prices from an orderly transaction between market participants provided by reputable broker-dealers or independent pricing services. In determining the value of a particular investment, independent pricing services may use information with respect to transactions in such investments, broker quotes, pricing matrices, market transactions in comparable investments and various relationships between investments. As part of its independent price verification process, the Company generally performs reviews of valuations provided by broker-dealers or independent pricing services. Investments in funds are valued at their closing price or NAV (or its equivalent) as a practical expedient. In the absence of observable market prices, the Company values its investments using valuation methodologies applied on a consistent basis. For some investments, little market activity may exist; management's determination of fair value is then based on the best information available in the circumstances, and may incorporate management's own assumptions and involve a significant degree of judgment, taking into consideration a combination of internal and external factors. Such investments are valued no less than quarterly, taking into consideration any changes in key inputs and changes in economic and other relevant conditions, and valuation models are updated accordingly. The Company has established a valuation committee to administer, implement and oversee the valuation policies and procedures (the Valuation Committee). Additionally, the Company has retained an independent valuation services firm to assist in the determination of the fair value of certain private real estate investments. The following table summarizes the valuation techniques and significant unobservable inputs approved by the Valuation Committee for Level 3 investments measured at fair value on a recurring basis: Fair Value as of December 31, 2024 (in thousands) Valuation Technique Unobservable Inputs Range Weighted Average Limited partnership interests $32,552 Discounted cash flow Discount rate 7.00% - 10.50% 5.25% - 8.75% 8.82% 7.39% Fair Value as of December 31, 2023 (in thousands) Valuation Technique Unobservable Inputs Value Weighted Average Limited partnership interests $13,202 Discounted cash flow Discount rate 9.25% 7.75% 9.25% 7.75% Transaction price n/a Changes in the significant unobservable inputs in the above tables may result in a materially higher or lower fair value measurement.

Stock-Based Compensation	Stock-Based Compensation Amended and Restated Stock Incentive Plan The Amended and Restated Cohen & Steers, Inc. Stock Incentive Plan (the SIP) provides for the issuance of Restricted Stock Units (RSUs), stock options and other stock-based awards to eligible employees and directors. The SIP was amended in 2022 to (i) extend the term for an additional ten years through May 5, 2032, and (ii) increase the number of shares of common stock of the Company with respect to which awards may be granted under the plan. As of December 31, 2024, a total of 23.0 million shares of common stock may be granted under the SIP. The board of directors is authorized to increase the number of shares available for issuance under the SIP, subject to shareholder approval. At December 31, 2024, a total of 20.1 million RSUs, representing the same amount of common stock, had been issued under the SIP. As of December 31, 2024, there was $65.7 million of compensation related to unamortized RSUs that had not yet been recognized in the consolidated statement of operations. The Company expects to recognize this expense over approximately the next three years. In January 2025, the Company granted approximately 511,000 RSUs under the SIP with a grant date fair value of $45.3 million, which generally vest over a four-year period. Restricted Stock Units Vested Restricted Stock Unit Grants The Company grants awards of vested RSUs to the non-management directors and certain employees of the Company pursuant to the SIP. The fair value at the date of grant is fully expensed. Dividends declared on these awards are paid in cash. In connection with the grant of these vested RSUs, the Company recorded non-cash stock-based compensation expense of $0.8 million, $1.0 million and $2.7 million for the years ended December 31, 2024, 2023 and 2022, respectively. Unvested Restricted Stock Unit Grants From time to time, the Company grants awards of unvested RSUs to certain employees pursuant to the SIP. The fair value at the date of grant is expensed on a straight-line basis over the applicable service period, which is generally four years. Dividends declared by the Company are paid in additional RSUs which are subject to forfeiture until they are delivered. The dividend equivalent RSUs will generally vest and be delivered on the fourth anniversary of the original grant date. The Company recorded non-cash stock-based compensation expense related to these awards, net of forfeitures, of $8.8 million for each of the years ended December 31, 2024, 2023 and 2022. Incentive Bonus Plans for Employees of the Company The Company has implemented a program for employees which, based upon compensation levels, automatically defers a portion of their total compensation in the form of unvested RSUs (Mandatory Program). The fair value at the date of grant of the RSUs under the Mandatory Program is expensed on a straight-line basis over the vesting period, which is typically four years. Dividends declared by the Company are paid in additional RSUs which are subject to forfeiture until they are delivered. The dividend equivalent RSUs will generally vest and be delivered on the fourth anniversary of the original grant date. The Company recorded non-cash stock-based compensation expense under the Mandatory Program, net of forfeitures, of $42.5 million, $34.4 million and $37.5 million for the years ended December 31, 2024, 2023 and 2022, respectively.

Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	Cybersecurity is a crucial component of our enterprise risk management program. We have implemented and maintain various information security processes designed to identify, assess and manage material risks from cybersecurity threats to our critical computer networks, third party hosted services, communications systems, hardware and software and our critical data, including intellectual property, confidential information that is proprietary, strategic or competitive in nature and information relating to our clients and investments. Our cybersecurity risk management function is led by our Cybersecurity Management team which is comprised of our Chief Information Security Officer (CISO), Chief Technology Officer (CTO), members of our Information Technology (IT) department, as well as members of our Legal and Compliance Departments. Our Cybersecurity Management team is primarily responsible for developing, implementing and monitoring our cybersecurity program and reporting on cybersecurity matters to senior management as well as our board of directors. Members of our Cybersecurity Management identify and assess risks from cybersecurity threats by monitoring our threat environment and the Company’s enterprise risk profile using various manual and automated tools as well as by: (i) utilizing shared information about vulnerabilities and exploits from professional security organizations, reports or other services that identify cybersecurity threats and through the use of external intelligence feeds; (ii) analyzing reports of threats and actors; (iii) conducting periodic vulnerability scans of the Company’s IT environment; (iv) evaluating our and our industry’s risk profile; (v) evaluating threats that are reported to us; (vi) coordinating with law enforcement concerning threats; (vii) conducting internal and external audits of our information security control environment and operating effectiveness; and (viii) conducting threat assessments for internal and external threats, including through the use of third party threat assessments and vulnerability threat assessments. We implement and maintain various technical, physical and organizational measures, processes, standards and policies designed to manage and mitigate material risks from cybersecurity threats, including, but not limited to: • technical and physical safeguards : (i) real-time security information and event monitoring of systems, workstations, servers and networks, and periodic internal and external vulnerability scans; (ii) asset management tracking and disposal; (iii) incident detection and response; (iv) data encryption; (v) notification monitoring from Company personnel and from third parties regarding issues and signs of potential incidents; and (vi) logical access controls and network security controls; and • organizational safeguards : (i) incident response plans that address our response to a cybersecurity incident; (ii) personnel and vendors dedicated to overseeing the Company’s cybersecurity program; (iii) periodic mandatory employee cybersecurity training; (iv) periodic risk assessments and testing of our policies, standards, processes and practices designed to address cybersecurity threats and incidents; (v) policies and programs such as security standards, a vendor risk management program, a vulnerability management policy and disaster recovery and business continuity plans; and (vi) insurance coverage dedicated to losses resulting from cybersecurity incidents. Cybersecurity risk management is integrated into the Company’s overall enterprise risk management (ERM) process. For example, (i) enterprise risk management-level cybersecurity risks are reviewed at least annually by our information technology security team; (ii) internal and external penetration tests are performed to identify vulnerabilities and findings are risk ranked based on potential likelihood and impact; and (iii) members of Cybersecurity Management report on cybersecurity risk management and related matters to the audit committee of the board of directors, as part of their ongoing evaluation and oversight of overall enterprise risk pursuant to non-exclusive authority delegated by the board of directors. We use third-party service providers to assist us in identifying, assessing and monitoring material risks from cybersecurity threats, including through penetration testing, provision of threat intelligence and continuous monitoring of our environment. We report key findings to the audit committee of the board of directors and, if appropriate, the board of directors and adjust our cybersecurity policies, standards, processes and practices as necessary based in part on information provided by these assessments and engagements. We also use third-party service providers to perform a variety of functions throughout our business, such as application providers, hosting companies and supply chain resources. We maintain a risk-based approach to identifying and overseeing cybersecurity risks and vulnerabilities presented by our engagement of third parties, as well as the information systems of third parties that could adversely impact our business in the event of a cybersecurity incident affecting those third-party systems. Our vendor risk management program may involve different assessments designed to help identify cybersecurity risks including: (i) vendor risk assessments; (ii) security questionnaires; (iii) vendor audits; (iv) vulnerability scans relating to vendors; (v) security assessment calls with the vendor’s security personnel and our review of the vendor’s written security program, security assessments and other reports; (vi) evidence of cybersecurity preparedness through a System and Organization Controls (SOC) 1 or SOC 2 report; and (vii) the imposition of contractual obligations on the vendor. For a description of the risks from cybersecurity threats that may materially affect the Company, see our risk factors under Part 1. Item 1A. Risk Factors in this Annual Report on Form 10-K, including under the caption “We could incur financial losses, reputational harm and regulatory penalties if we fail to implement effective information security policies and procedures.”

Accounting Policies [Abstract]
Recently Adopted Accounting Pronouncements and New Accounting Pronouncements	Recently Adopted Accounting Pronouncements —In June 2022, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update 2022-03 (ASU), Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions . The standard clarifies that contractual sale restrictions are not considered in measuring the fair value of equity securities, which would be a change in practice for certain entities. The ASU also indicates that a contractual sale restriction is not a separate unit of account, and requires new disclosures for all entities with equity securities subject to a contractual sale restriction. This new guidance became effective on January 1, 2024. The Company's adoption of this new standard did not have an impact on the Company's consolidated financial statements. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures . The standard requires enhanced disclosure of reportable segments and additional information about a segment’s expenses. This new guidance became effective on January 1, 2024. The Company's adoption of this standard did not have a material impact on the Company's consolidated financial statements. Refer to Note 18 for further discussion. New Accounting Pronouncements Not Yet Implemented —In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures . The standard requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as additional information on income taxes paid. The standard is intended to benefit investors by providing more detailed income tax disclosures that would be useful in making capital allocation decisions. This new guidance became effective on January 1, 2025. The Company does not expect that the adoption of this new standard will have a material effect on the Company's consolidated financial statements and related disclosures. In March 2024, the FASB issued ASU 2024-01, Compensation-Stock Compensation (Topic 718): Scope Application of Profits Interest and Similar Awards . The standard clarifies how an entity determines whether a profits interest or similar award is (1) within the scope of Topic 718 or (2) not a share-based payment arrangement and therefore within the scope of other guidance. The guidance in ASU 2024-01 applies to all entities that issue profits interest awards as compensation to employees or nonemployees in exchange for goods or services. This new guidance became effective on January 1, 2025. The Company does not expect that the adoption of this new standard will have a material effect on the Company's consolidated financial statements and related disclosures. In November 2024, the FASB issued ASU 2024-03, Income Statement — Reporting Comprehensive Income — Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses . The standard requires disaggregation of certain expense captions into specified categories in disclosures within the footnotes to the financial statements. This new guidance will be effective on January 1, 2027 for annual reporting and January 1, 2028 for interim reporting. The Company is currently evaluating the impact that the adoption of this new standard will have on the Company's consolidated financial statements and related disclosures.
Consolidation of Company-sponsored Funds	Consolidation of Investment Vehicles —The Company's financial interests in investment vehicles, including the management fees that are received, are evaluated at inception and thereafter, if there is a reconsideration event, in order to determine whether to apply the Variable Interest Entity (VIE) model or the Voting Interest Entity (VOE) model. A VIE is an entity in which either the equity investment at risk is not sufficient to permit the entity to finance its own activities without additional financial support or the group of holders of the equity investment at risk lack certain characteristics of a controlling financial interest. The primary beneficiary is the entity that has the power to direct the activities of the VIE that most significantly affect its performance, and the obligation to absorb losses of the entity or the right to receive benefits from the entity that could potentially be significant to the VIE. Subscriptions and redemptions or amendments to the governing documents of the respective entities could affect an entity's status as a VIE or the determination of the primary beneficiary. Limited partnerships and similar entities are determined to be a VIE generally when the Company is the general partner and the limited partners do not hold substantive kick-out or participation rights. The Company assesses whether it is the primary beneficiary of any VIEs identified by evaluating its economic interests in the entity held either directly by the Company and its affiliates or indirectly through employees. VIEs for which the Company is deemed to be the primary beneficiary are consolidated. Investments that are determined to be VOEs are consolidated when the Company’s ownership interest is greater than 50% of the outstanding voting interests of the vehicle. The Company records noncontrolling interests in consolidated funds for which the Company’s ownership is less than 100%.
Cash and Cash Equivalents	Cash and Cash Equivalents —Cash and cash equivalents include short-term, highly liquid investments, which are readily convertible into cash.
Due from/to Brokers	Due from/to Brokers —The Company, including the consolidated funds, may transact with brokers for certain investment activities. The clearing and custody operations for these investment activities are performed pursuant to contractual agreements. The due from/to brokers balances represent cash and/or collateral balances at brokers/custodians and/or receivables and payables for unsettled securities transactions with brokers/custodians.
Investments	Investments —Management of the Company determines the appropriate classification of its investments at the time of purchase and re-evaluates such determination no less than quarterly. The Company's investments are categorized as follows: • Equity investments at fair value generally represent common stocks, limited partnership interests, exchange-traded preferred securities, and seed investments in Company-sponsored vehicles including its Non-Traded REIT. • Trading investments generally represent U.S. Treasury securities, over-the-counter preferred securities and investment-grade corporate debt securities. The Company has elected the fair value option for a seed investment that otherwise would have been accounted for using the equity method of accounting. Distributions from this seed investment are recorded in interest and dividend income—net in the Company's consolidated statements of operations when earned. Gains and losses on the Company's investments, including those for which the fair value option has been elected, are recorded in gain (loss) from investments—net in the Company's consolidated statements of operations. From time to time, the Company, including the consolidated funds, may enter into forward foreign exchange contracts to economically hedge currency exposure, and derivative contracts, including options, futures and swaps contracts, to gain exposure to the underlying commodities markets or to economically hedge market risk of the underlying portfolios.
Leases	Leases —The Company determines if an arrangement is a lease at inception. The Company has operating leases for corporate offices and certain information technology equipment which are included in operating lease right-of-use (ROU) assets and operating lease liabilities on the Company’s consolidated statements of financial condition. ROU assets represent the right to use an underlying asset for the lease term and lease liabilities represent obligations to make lease payments arising from the lease. Operating lease ROU assets and lease liabilities are recognized at commencement date based on the net present value of lease payments over the life of the lease and thereafter, are remeasured if there is a change in lease terms. The majority of the Company’s lease agreements do not provide an implicit rate. As a result, the Company uses an estimated incremental borrowing rate based on the information available as of the applicable lease commencement date in determining the present value of lease payments. The operating lease ROU assets reflect any upfront lease payments made as well as lease incentives received. The lease terms may include options to extend or terminate the lease and these are factored into the determination of the ROU asset and lease liability at lease inception when and if it is reasonably certain that the Company will exercise that option. Lease expense for fixed lease payments is recognized on a straight-line basis over the lease term. The Company has certain lease agreements with non-lease components such as maintenance and executory costs, which are accounted for separately and not included in ROU assets. ROU assets are tested for impairment whenever changes in facts or circumstances indicate that the carrying amount of an asset may not be recoverable. Modification of a lease term would result in remeasurement of the lease liability and a corresponding adjustment to the ROU asset.
Noncontrolling Interests	Noncontrolling Interests —Noncontrolling interests consist of nonredeemable and redeemable third-party interests in the Company's consolidated funds. Noncontrolling interests that are not redeemable at the option of the investors are classified as nonredeemable noncontrolling interests and are included in stockholders’ equity. Noncontrolling interests that are redeemable at the option of the investors are classified as redeemable noncontrolling interests and are not treated as permanent equity. Noncontrolling interests are recorded at fair value which approximates the net asset value at each reporting date.
Investment Advisory and Administration Fees	Investment Advisory and Administration Fees —The Company earns revenue by providing asset management services to institutional accounts, open-end and closed-end funds as well as model-based portfolios. Investment advisory fees are earned pursuant to the terms of investment management agreements and are generally based on a contractual fee rate applied to the average assets under management. The Company also earns administration fees from certain open-end and closed-end funds pursuant to the terms of underlying administration contracts. Administration fees are based on the average daily assets under management of such funds. Investment advisory and administration fee revenue is recognized when earned and is recorded net of any fund reimbursements. The investment advisory and administration contracts each include a single performance obligation as the services provided are not separately identifiable and are accounted for as a series satisfied over time using a time-based method (days elapsed). Additionally, investment advisory and administration fees represent variable consideration, as fees are based on average assets under management which fluctuate daily. In certain instances, the Company may earn performance fees when specified performance hurdles are met during the performance period. Performance fees are forms of variable consideration and are not recognized until it becomes probable that there will not be a significant reversal of the cumulative revenue recognized .
Distribution and Service Fee Revenue	Distribution and Service Fee Revenue —Distribution and service fee revenue is based on the average daily net assets of certain share classes of U.S. open-end funds. Distribution and service fee revenue is earned daily and is recorded gross of any third-party distribution and service fee expense for applicable share classes. Distribution fee agreements include a single performance obligation that is satisfied at a point in time when an investor purchases shares of an open-end fund. For all periods presented, a portion of the distribution fee revenue recognized in the period may relate to performance obligations satisfied (or partially satisfied) in prior periods. Service fee agreements include a single performance obligation as the services provided are not separately identifiable and are accounted for as a series satisfied over time using a time-based method (days elapsed). Additionally, distribution and service fees represent variable consideration, as fees are based on average assets under management which fluctuate daily.
Distribution and Service Fee Expense	Distribution and Service Fee Expense —Distribution and service fee expense includes distribution fees, shareholder servicing fees and intermediary assistance payments. Distribution fees represent payments made to qualified intermediaries for assistance in connection with the distribution of certain open-end funds' shares and for other expenses such as advertising, printing and distribution of prospectuses to investors. Such amounts may also be used to pay financial intermediaries for services as specified in the terms of written agreements complying with Rule 12b-1 of the Investment Company Act of 1940. Distribution fees are based on average daily net assets under management of certain share classes of certain of the funds. Shareholder servicing fees represent payments made to qualified intermediaries for shareholder account service and maintenance. These services are provided pursuant to written agreements with such qualified institutions. Shareholder servicing fees are generally based on average daily net assets under management. Intermediary assistance payments represent payments to qualified intermediaries for activities related to distribution, shareholder servicing as well as marketing and support of certain open-end funds and are incremental to those described above. Intermediary assistance payments are generally based on average daily net assets under management.
Stock-based Compensation	Stock-based Compensation —The Company recognizes compensation expense for the grant-date fair value of restricted stock unit awards to certain employees. This expense is recognized over the period during which employees are required to provide service. Forfeitures are recorded as incurred. Any change to the key terms of an employee’s award subsequent to the grant date is evaluated and, if necessary, accounted for as a modification. If the modification results in the remeasurement of the fair value of the award, the remeasured compensation cost is recognized over the remaining service period.
Income Taxes	Income Taxes —The Company records the current and deferred tax consequences of all transactions that have been recognized in the consolidated financial statements in accordance with the provisions of the enacted tax laws. Deferred tax assets are recognized for temporary differences that will result in deductible amounts in future years at tax rates that are expected to apply in those years. The Company records a valuation allowance, when necessary, to reduce deferred tax assets to an amount that more likely than not will be realized. Deferred tax liabilities are recognized for temporary differences that will result in taxable income in future years at tax rates that are expected to apply in those years. The calculation of tax liabilities involves uncertainties in the application of complex tax laws and regulations across the Company's global operations. A tax benefit from an uncertain tax position is recognized when it is more likely than not that the position will be sustained upon examination, including resolution of any related appeals or litigation processes, on the basis of the technical merits. The Company records potential interest and penalties related to uncertain tax positions in the provision for income taxes in the consolidated statements of operations.
Earnings Per Share, Policy	Earnings Per Share —Basic earnings per share is calculated by dividing net income attributable to common stockholders by the weighted average shares outstanding. Diluted earnings per share is calculated by dividing net income attributable to common stockholders by the total weighted average shares of common stock outstanding and common stock equivalents determined using the treasury stock method. Common stock equivalents are comprised of dilutive potential shares from restricted stock unit awards and are excluded from the computation if their effect is anti-dilutive.
Currency Translation and Transactions	Currency Translation and Transactions —Assets and liabilities of subsidiaries having non-U.S. dollar functional currencies are translated at exchange rates at the applicable consolidated statement of financial condition date. Revenue and expenses of such subsidiaries are translated at average exchange rates during the period. The gains or losses resulting from translating non-U.S. dollar functional currency into U.S. dollars are included in the Company's consolidated statements of comprehensive income. The cumulative translation adjustment was $(10.0) million, $(7.7) million and $(10.8) million as of December 31, 2024, 2023 and 2022, respectively, and was reported within accumulated other comprehensive income (loss) on the consolidated statements of financial condition. Gains or losses resulting from transactions denominated in currencies other than the functional currency of each respective entity and gains and losses arising on remeasurement of U.S. dollar-denominated assets and liabilities held by certain foreign subsidiaries are included in foreign currency gain (loss)—net in the Company’s consolidated statements of operations.
Valuation Techniques	Valuation Techniques In certain instances, debt and equity securities are valued on the basis of prices from an orderly transaction between market participants provided by reputable broker-dealers or independent pricing services. In determining the value of a particular investment, independent pricing services may use information with respect to transactions in such investments, broker quotes, pricing matrices, market transactions in comparable investments and various relationships between investments. As part of its independent price verification process, the Company generally performs reviews of valuations provided by broker-dealers or independent pricing services. Investments in funds are valued at their closing price or NAV (or its equivalent) as a practical expedient. In the absence of observable market prices, the Company values its investments using valuation methodologies applied on a consistent basis. For some investments, little market activity may exist; management's determination of fair value is then based on the best information available in the circumstances, and may incorporate management's own assumptions and involve a significant degree of judgment, taking into consideration a combination of internal and external factors. Such investments are valued no less than quarterly, taking into consideration any changes in key inputs and changes in economic and other relevant conditions, and valuation models are updated accordingly. The Company has established a valuation committee to administer, implement and oversee the valuation policies and procedures (the Valuation Committee). Additionally, the Company has retained an independent valuation services firm to assist in the determination of the fair value of certain private real estate investments. The following table summarizes the valuation techniques and significant unobservable inputs approved by the Valuation Committee for Level 3 investments measured at fair value on a recurring basis: Fair Value as of December 31, 2024 (in thousands) Valuation Technique Unobservable Inputs Range Weighted Average Limited partnership interests $32,552 Discounted cash flow Discount rate 7.00% - 10.50% 5.25% - 8.75% 8.82% 7.39% Fair Value as of December 31, 2023 (in thousands) Valuation Technique Unobservable Inputs Value Weighted Average Limited partnership interests $13,202 Discounted cash flow Discount rate 9.25% 7.75% 9.25% 7.75% Transaction price n/a Changes in the significant unobservable inputs in the above tables may result in a materially higher or lower fair value measurement.
