Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	Basis of Presentation and Significant Accounting Policies The condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). The condensed consolidated financial statements set forth herein include the accounts of CNS and its direct and indirect subsidiaries. Intercompany balances and transactions have been eliminated in consolidation. The condensed consolidated financial statements of the Company included herein are unaudited and have been prepared in accordance with the instructions to Form 10-Q pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). In the opinion of management, all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation of the interim results have been made. The Company's condensed consolidated financial statements and the related notes should be read together with the consolidated financial statements and the related notes included in the Company's Annual Report on Form 10-K for the year ended December 31, 2020. Recently Adopted Accounting Pronouncements —In December 2019, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update 2019-12, Income Taxes (Topic 740) : Simplifying Accounting for Income Taxes . The standard is intended to simplify various aspects related to income taxes and removes certain exceptions to the general principles in Topic 740. This new guidance became effective on January 1, 2021. The Company's adoption of the new standard did not have a material effect on its condensed consolidated financial statements and related disclosures. Accounting Estimates —The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosures of contingent assets and liabilities at the dates of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. Management believes the estimates used in preparing the condensed consolidated financial statements are reasonable and prudent. Actual results could differ from those estimates. Consolidation of Company-sponsored Funds —Investments in Company-sponsored funds and management fees 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. In performing this analysis, all of the Company's management fees are presumed to be commensurate and at market and are therefore not considered variable interests. A VIE is an entity in which either (i) the equity investment at risk is not sufficient to permit the entity to finance its own activities without additional financial support or (ii) 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 (i) the power to direct the activities of the VIE that most significantly affect its performance, and (ii) 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. Investments 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. 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 in Company-sponsored funds 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 fund or when the Company is the general partner of the fund and the limited partners do not have substantive kick-out or participating rights in the fund. The Company records noncontrolling interests in consolidated Company-sponsored funds for which the Company's ownership is less than 100%. Cash and Cash Equivalents —Cash and cash equivalents are on deposit with several highly rated financial institutions and include short-term, highly-liquid investments, which are readily convertible into cash and have original maturities of three months or less. Due from/to Brokers —The Company, including the consolidated Company-sponsored 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 balance represents cash and/or cash collateral balances at brokers/custodians and/or receivables and payables for unsettled securities transactions with brokers. 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 on a quarterly basis. At March 31, 2021, the Company's investments were comprised of the following: • Equity investments at fair value, which generally represent equity securities held within the consolidated Company-sponsored funds, listed equity securities held directly for the purposes of establishing performance track records and seed investments in Company-sponsored open-end funds where the Company has neither control nor the ability to exercise significant influence. • Trading investments, which generally represent debt securities held within the consolidated Company-sponsored funds and listed debt securities held directly for the purposes of establishing performance track records. • Held-to-maturity investments, if any, generally represent corporate investments in U.S. Treasury securities recorded at amortized cost. Under the current expected credit loss model, any expected credit losses are recognized as an allowance, which represents an adjustment to the amortized costs basis. The Company did not hold any held-to-maturity investments at March 31, 2021. • Equity method investments, which generally represent seed investments in Company-sponsored funds in which the Company owns between 20-50% of the outstanding voting interests or when it is determined that the Company is able to exercise significant influence but not control over the investments. When using the equity method, the Company recognizes its respective share of net income or loss for the period which is recorded as gain (loss) from investments—net in the Company's condensed consolidated statements of operations. Realized and unrealized gains and losses on equity investments at fair value, trading investments and equity method investments are recorded in gain (loss) from investments—net in the Company's condensed consolidated statements of operations. From time to time, the Company, including the consolidated Company-sponsored funds, may enter into 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. Gains and losses on derivative contracts are recorded as gain (loss) from investments—net in the Company's condensed consolidated statements of operations. The fair values of these instruments are recorded in other assets or other liabilities and accrued expenses on the Company's condensed consolidated statements of financial condition. Additionally, from time to time, the Company, including the consolidated Company-sponsored funds, may enter into forward foreign exchange contracts to economically hedge its currency exposure. These instruments are measured at fair value based on the prevailing forward exchange rate with gains and losses recorded in foreign currency gain (loss)—net in the Company’s condensed consolidated statements of operations. The fair values of these contracts are recorded in other assets or other liabilities and accrued expenses on the Company’s condensed consolidated statements of financial condition. 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 and these leases are included in operating lease right-of-use (ROU) assets and operating lease liabilities on the Company’s condensed 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 lease term. The majority of the Company’s lease agreements do not provide an implicit rate. As a result, the Company used an incremental borrowing rate based on the information available as of lease commencement dates in determining the present value of lease payments. The operating lease ROU asset reflects 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 re-measurement of the lease liability and a corresponding adjustment to the ROU asset. Goodwill and Intangible Assets —Goodwill represents the excess of the cost of the Company's investment in the net assets of an acquired company over the fair value of the underlying identifiable net assets at the date of acquisition. Goodwill and indefinite-lived intangible assets are not amortized but are tested at least annually for impairment by comparing the fair value to their carrying amounts. Redeemable Noncontrolling Interests —Redeemable noncontrolling interests represent third-party interests in the consolidated Company-sponsored funds. These interests are redeemable at the option of the investors and therefore are not treated as permanent equity. Redeemable noncontrolling interest is recorded at fair value which approximates the redemption value at each reporting period. Investment Advisory and Administration Fees —The Company earns revenue by providing asset management services to institutional accounts, Company-sponsored 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 Company-sponsored 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 the Company's sponsored open-end funds distributed by CSS. Distribution and service fee revenue is earned daily and is generally 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 in a Company-sponsored open-end fund. Distribution fees represent variable consideration, as fees are based on average assets under management which fluctuate daily. 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). 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 and service fee expense is recorded on an accrual basis. Distribution fees represent payments made to qualified intermediaries for (i) assistance in connection with the distribution of the Company's sponsored open-end funds' shares and (ii) 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 the 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 the average daily 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 the Company's sponsored open-end funds and are incremental to those described above. Intermediary assistance payments are generally based on the average assets under management. Stock-based Compensation —The Company recognizes compensation expense for the grant-date fair value of awards of equity instruments to certain employees. This expense is recognized over the period during which employees are required to provide service. Forfeitures are recorded as incurred. Income Taxes —The Company records the current and deferred tax consequences of all transactions that have been recognized in the condensed 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. 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 Company records a valuation allowance, when necessary, to reduce deferred tax assets to an amount that more likely than not will be realized. The effective tax rate for interim periods is based on the Company's best estimate of the effective tax rate expected to be applied to the full fiscal year adjusted for discrete items during the period. 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 condensed consolidated statements of operations. Currency Translation and Transactions —Assets and liabilities of subsidiaries having non-U.S. dollar functional currencies are translated at exchange rates at the applicable condensed consolidated statement of financial condition date.

Fair Value Disclosures [Abstract]
Fair Value	Fair Value Accounting Standards Codification Topic 820, Fair Value Measurement (ASC 820) 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 the three broad levels listed below: • 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. Inputs used to measure fair value might fall in different levels of the fair value hierarchy, in which case the Company defaults to the lowest level input that is significant to the fair value measurement in its entirety. These levels are not necessarily an indication of the risk or liquidity associated with the investments. The following tables present fair value measurements: March 31, 2021 (in thousands) Level 1 Level 2 Level 3 Investments Total Cash equivalents $ 30,596 $ — $ — $ — $ 30,596 Equity investments at fair value: Common stocks $ 97,246 $ 224 $ — $ — $ 97,470 Company-sponsored funds 174 — — — 174 Limited partnership interests 965 — — 265 1,230 Preferred securities 1,466 18 — — 1,484 Other — — — 128 128 Total $ 99,851 $ 242 $ — $ 393 $ 100,486 Trading investments: Fixed income $ — $ 27,936 $ — $ — $ 27,936 Equity method investments $ — $ — $ — $ 15 $ 15 Total investments $ 99,851 $ 28,178 $ — $ 408 $ 128,437 Derivatives - assets: Futures - commodities $ 783 $ — $ — $ — $ 783 Total return swaps - commodities — 147 — — 147 Forward contracts - foreign exchange — 801 — — 801 Total $ 783 $ 948 $ — $ — $ 1,731 Derivatives - liabilities: Futures - commodities $ 630 $ — $ — $ — $ 630 Total return swaps - commodities (1) — 210 — — 210 Total return swaps - equities — 1,078 — — 1,078 Forward contracts - foreign exchange — 12 — — 12 Total $ 630 $ 1,300 $ — $ — $ 1,930 ________________________ (1) Included total return swaps - commodities held by consolidated Company-sponsored funds.

Equity investments at fair value classified as level 2 were comprised of common stocks and preferred securities with predominately equity-like characteristics for which quoted prices in active markets are not available. Fair values for the common stocks classified as level 2 were generally based on quoted prices for similar instruments in active markets. Fair values for the preferred securities classified as level 2 were generally determined using third-party pricing services. The pricing services may utilize pricing models, and inputs into those models may include reported trades, executable bid and ask prices, broker-dealer quotations, prices or yields of similar securities, benchmark curves and other market information. The pricing services may use a matrix approach, which considers information regarding securities with similar characteristics to determine the valuation for a security. Trading investments classified as level 2 were comprised of U.S. Treasury securities and corporate debt securities. The fair value amounts 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. These investments were comprised of: • Equity investments at fair value - included limited partner interests in limited partnership vehicles that invest in non-registered real estate funds and the Company's co-investment in a Cayman trust invested in global listed infrastructure securities (which is included in "Other" in the leveling table), both of which are valued based on the NAVs of the underlying investments. At March 31, 2021 and December 31, 2020, the Company did not have the ability to redeem the interests in the limited partnership vehicles; there were no contractual restrictions on the Company's ability to redeem its interest in the Cayman trust. • Equity method investments - included the Company's partnership interests in the Cohen & Steers Global Realty Partners III-TE, L.P. (GRP-TE) at March 31, 2021 and December 31, 2020. GRP-TE invests in non-registered real estate funds. The Company's ownership interest was approximately 0.2% and the Company did not have the ability to redeem the investment at either March 31, 2021 or December 31, 2020. In addition, at December 31, 2020, the Cohen & Steers Global Realty Focus Fund (GRF), a series of Cohen & Steers Series LP was included. During the first quarter of 2021, GRF was redeemed. Held-to-maturity investments at December 31, 2020, were comprised of U.S. Treasury securities, which were directly issued by the U.S. government. These securities were purchased with the intent to hold to maturity and were recorded at amortized cost. Investments measured at NAV and held-to-maturity investments 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 condensed consolidated statements of financial condition. 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. Valuation Techniques In certain instances, debt, equity and preferred 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 Company-sponsored 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, which are generally immaterial, are valued on a quarterly basis, taking into consideration any changes in key inputs and changes in economic and other relevant conditions, and valuation models are updated accordingly. The valuation process also includes a review by the Company's valuation committee which is comprised of senior members from various departments within the Company, including investment management. The valuation committee provides independent oversight of the valuation policies and procedures.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The provision for income taxes included U.S. federal, state, local and foreign taxes. The effective tax rate for the three months ended March 31, 2021 was approximately 8.4%, compared with approximately 2.2% for the three months ended March 31, 2020. The effective tax rate for the three months ended March 31, 2021 differed from the U.S. federal statutory rate of 21.0% primarily due to state, local and foreign income taxes which were more than offset by discrete tax items, primarily related to the reversal of certain liabilities associated with unrecognized tax benefits and the appreciated value of the restricted stock units delivered in January 2021. The effective tax rate for the three months ended March 31, 2020 differed from the U.S. federal statutory rate of 21.0% primarily due to state, local and foreign income taxes which were more than offset by discrete tax items primarily related to the appreciated value of restricted stock units delivered in January 2020.Deferred income taxes represent the tax effects of the temporary differences between book and tax bases and are measured using enacted tax rates that will be in effect when such items are expected to reverse. The Company's net deferred tax asset was primarily comprised of future income tax deductions attributable to the delivery of unvested restricted stock units. The Company records a valuation allowance, when necessary, to reduce deferred tax assets to an amount that more likely than not will be realized.

Accounting Policies [Abstract]
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements —In December 2019, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update 2019-12, Income Taxes (Topic 740) : Simplifying Accounting for Income Taxes . The standard is intended to simplify various aspects related to income taxes and removes certain exceptions to the general principles in Topic 740. This new guidance became effective on January 1, 2021. The Company's adoption of the new standard did not have a material effect on its condensed consolidated financial statements and related disclosures.
Accounting Estimates	Accounting Estimates —The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosures of contingent assets and liabilities at the dates of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. Management believes the estimates used in preparing the condensed consolidated financial statements are reasonable and prudent. Actual results could differ from those estimates.
Consolidation of Company-sponsored Funds	Consolidation of Company-sponsored Funds —Investments in Company-sponsored funds and management fees 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. In performing this analysis, all of the Company's management fees are presumed to be commensurate and at market and are therefore not considered variable interests. A VIE is an entity in which either (i) the equity investment at risk is not sufficient to permit the entity to finance its own activities without additional financial support or (ii) 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 (i) the power to direct the activities of the VIE that most significantly affect its performance, and (ii) 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. Investments 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. 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.
Cash and Cash Equivalents	Cash and Cash Equivalents —Cash and cash equivalents are on deposit with several highly rated financial institutions and include short-term, highly-liquid investments, which are readily convertible into cash and have original maturities of three months or less.
Due from/to Brokers	Due from/to Brokers —The Company, including the consolidated Company-sponsored 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 balance represents cash and/or cash collateral balances at brokers/custodians and/or receivables and payables for unsettled securities transactions with brokers.
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 on a quarterly basis. At March 31, 2021, the Company's investments were comprised of the following: • Equity investments at fair value, which generally represent equity securities held within the consolidated Company-sponsored funds, listed equity securities held directly for the purposes of establishing performance track records and seed investments in Company-sponsored open-end funds where the Company has neither control nor the ability to exercise significant influence. • Trading investments, which generally represent debt securities held within the consolidated Company-sponsored funds and listed debt securities held directly for the purposes of establishing performance track records. • Held-to-maturity investments, if any, generally represent corporate investments in U.S. Treasury securities recorded at amortized cost. Under the current expected credit loss model, any expected credit losses are recognized as an allowance, which represents an adjustment to the amortized costs basis. The Company did not hold any held-to-maturity investments at March 31, 2021. • Equity method investments, which generally represent seed investments in Company-sponsored funds in which the Company owns between 20-50% of the outstanding voting interests or when it is determined that the Company is able to exercise significant influence but not control over the investments. When using the equity method, the Company recognizes its respective share of net income or loss for the period which is recorded as gain (loss) from investments—net in the Company's condensed consolidated statements of operations. Realized and unrealized gains and losses on equity investments at fair value, trading investments and equity method investments are recorded in gain (loss) from investments—net in the Company's condensed consolidated statements of operations. From time to time, the Company, including the consolidated Company-sponsored funds, may enter into 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. Gains and losses on derivative contracts are recorded as gain (loss) from investments—net in the Company's condensed consolidated statements of operations. The fair values of these instruments are recorded in other assets or other liabilities and accrued expenses on the Company's condensed consolidated statements of financial condition. Additionally, from time to time, the Company, including the consolidated Company-sponsored funds, may enter into forward foreign exchange contracts to economically hedge its currency exposure. These instruments are measured at fair value based on the prevailing forward exchange rate with gains and losses recorded in foreign currency gain (loss)—net in the Company’s condensed consolidated statements of operations. The fair values of these contracts are recorded in other assets or other liabilities and accrued expenses on the Company’s condensed consolidated statements of financial condition.
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 and these leases are included in operating lease right-of-use (ROU) assets and operating lease liabilities on the Company’s condensed 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 lease term. The majority of the Company’s lease agreements do not provide an implicit rate. As a result, the Company used an incremental borrowing rate based on the information available as of lease commencement dates in determining the present value of lease payments. The operating lease ROU asset reflects 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 re-measurement of the lease liability and a corresponding adjustment to the ROU asset.
Goodwill and Intangible Assets	Goodwill and Intangible Assets —Goodwill represents the excess of the cost of the Company's investment in the net assets of an acquired company over the fair value of the underlying identifiable net assets at the date of acquisition. Goodwill and indefinite-lived intangible assets are not amortized but are tested at least annually for impairment by comparing the fair value to their carrying amounts.
Redeemable Noncontrolling Interests	Redeemable Noncontrolling Interests —Redeemable noncontrolling interests represent third-party interests in the consolidated Company-sponsored funds. These interests are redeemable at the option of the investors and therefore are not treated as permanent equity. Redeemable noncontrolling interest is recorded at fair value which approximates the redemption value at each reporting period.
Investment Advisory and Administration Fees	Investment Advisory and Administration Fees —The Company earns revenue by providing asset management services to institutional accounts, Company-sponsored 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 Company-sponsored 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 [Policy Text Block]	Distribution and Service Fee Revenue —Distribution and service fee revenue is based on the average daily net assets of certain share classes of the Company's sponsored open-end funds distributed by CSS. Distribution and service fee revenue is earned daily and is generally 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 in a Company-sponsored open-end fund. Distribution fees represent variable consideration, as fees are based on average assets under management which fluctuate daily. 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
Distribution and Service Fee Expense [Policy Text Block]	Distribution and Service Fee Expense —Distribution and service fee expense includes distribution fees, shareholder servicing fees and intermediary assistance payments. Distribution and service fee expense is recorded on an accrual basis. Distribution fees represent payments made to qualified intermediaries for (i) assistance in connection with the distribution of the Company's sponsored open-end funds' shares and (ii) 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 the 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 the average daily 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 the Company's sponsored open-end funds and are incremental to those described above. Intermediary assistance payments are generally based on the average assets under management.
Stock-based Compensation	Stock-based Compensation —The Company recognizes compensation expense for the grant-date fair value of awards of equity instruments to certain employees. This expense is recognized over the period during which employees are required to provide service. Forfeitures are recorded as incurred.
Income Taxes	Income Taxes —The Company records the current and deferred tax consequences of all transactions that have been recognized in the condensed 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. 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 Company records a valuation allowance, when necessary, to reduce deferred tax assets to an amount that more likely than not will be realized. The effective tax rate for interim periods is based on the Company's best estimate of the effective tax rate expected to be applied to the full fiscal year adjusted for discrete items during the period. 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 condensed consolidated statements of operations.
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 condensed 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 condensed consolidated statements of comprehensive income. The cumulative translation adjustment was $(4,729,000) and ($4,134,000) at March 31, 2021 and December 31, 2020, respectively. Gains or losses resulting from transactions denominated in currencies other than the U.S. dollar within certain foreign subsidiaries are included in non-operating income (loss) in the condensed consolidated statements of operations. Gains and losses arising on revaluation of U.S. dollar-denominated assets and liabilities held by foreign subsidiaries are also included in non-operating income (loss) in the Company’s condensed consolidated statements of operations.
Comprehensive Income	Comprehensive Income —The Company reports all changes in comprehensive income in the condensed consolidated statements of comprehensive income. Comprehensive income generally includes net income or loss attributable to common stockholders and amounts attributable to foreign currency translation gain (loss), net of tax.
Valuation Techniques	Valuation Techniques In certain instances, debt, equity and preferred 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 Company-sponsored 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, which are generally immaterial, are valued on a quarterly basis, taking into consideration any changes in key inputs and changes in economic and other relevant conditions, and valuation models are updated accordingly. The valuation process also includes a review by the Company's valuation committee which is comprised of senior members from various departments within the Company, including investment management. The valuation committee provides independent oversight of the valuation policies and procedures.
