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, 2018 . Recently Adopted Accounting Pronouncements —In February 2018, the Financial Accounting Standards Board (FASB) issued new guidance allowing entities to reclassify certain tax effects related to the enactment of the Tax Cuts and Jobs Act (the Tax Act) from accumulated other comprehensive income (AOCI) to retained earnings. Prior to the issuance of the new guidance, a portion of the previously recognized deferred tax effects recorded in AOCI was "left stranded" in AOCI as the effect of remeasuring the deferred taxes using the reduced federal corporate income tax rate was required to be recorded through income. The new guidance allows these stranded tax effects to be reclassified from AOCI to retained earnings. The new guidance became effective on January 1, 2019 and the Company adopted the standard using the prospective application. The Company's adoption of the new standard did not have a material effect on its consolidated financial statements and related disclosures. In February 2016, the FASB issued guidance introducing a new lease model which requires lessees to recognize leases on-balance sheet and disclose key information about leasing arrangements. The new guidance establishes a right-of-use model (ROU) that requires a lessee to recognize an ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. This new guidance became effective on January 1, 2019 and the Company adopted the standard, along with certain allowable practical expedients, using the modified retrospective transition approach, which required the recasting of prior period amounts. Other than the Company's condensed consolidated statements of financial condition, the adoption of the new standard had no material impact on its condensed consolidated financial statements. The adoption of the new leasing standard resulted in the following changes to the Company's condensed consolidated statement of financial condition for the year ended December 31, 2018 (in thousands): Previously Reported Adjustments Due to New Leasing Standard to record ROU assets and lease liabilities Reclassification of Deferred Rent Recast Operating lease right-of-use assets $ — $ 54,304 $ (5,816 ) $ 48,488 Operating lease liabilities $ — $ 54,304 $ — $ 54,304 Deferred rent $ 5,816 $ — $ (5,816 ) $ — 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 funds for which the Company's ownership is less than 100%. Cash and Cash Equivalents —Cash and cash equivalents are on deposit with three major financial institutions and consist of short-term, highly-liquid investments, which are readily convertible into cash and have original maturities of three months or less. Due from/to Brokers —Company-sponsored funds that are consolidated 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 cash equivalents balances at brokers/custodians and/or receivables and payables for unsettled securities transactions. 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, 2019 , the Company's investments were comprised of the following: • Equity investments at fair value, which includes securities held within the affiliated funds that the Company consolidates, individual 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 represent debt securities held within the affiliated funds that the Company consolidates and individual debt securities held directly for the purposes of establishing performance track records. • Held-to-maturity investments, which represent fixed income securities recorded at amortized cost. The Company periodically reviews held-to-maturity investments for other-than-temporary impairments (OTTI). If the Company believes an OTTI exists, an impairment charge will be recognized in the Company’s condensed consolidated statements of operations. • Equity method investments, which represent seed investments in which the Company owns between 20-50% of the outstanding voting interests in the affiliated fund 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 the affiliated investee fund 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 affiliated funds consolidated by the Company, enters into derivative contracts to gain exposure to the underlying commodities markets or to hedge market and credit risks of the underlying portfolios, including options, futures and swaps contracts. Gain 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. At March 31, 2019 , none of the outstanding derivative contracts were subject to a master netting agreement or other similar arrangement. Additionally, from time to time, the Company, including the affiliated funds consolidated by the Company, enters into foreign exchange contracts to 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 gains (losses)—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. Operating leases are included in operating lease 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 liabilities are recognized at commencement date based on the net present value of lease payments over the lease term. None of the Company’s lease agreements provide an implicit rate. As a result, the Company used an implied incremental borrowing rate based on the information available at 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 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. 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 affiliated funds that the Company consolidates. These interests are redeemable at the option of the investors and therefore are not treated as permanent equity. Redeemable noncontrolling interest is remeasured at redemption value which approximates the fair value at each reporting period. Investment Advisory and Administration Fees —The Company earns revenue by providing asset management services to institutional accounts and to Company-sponsored open-end and closed-end funds. Investment advisory fees are earned pursuant to the terms of investment management agreements and are based on a contractual fee rate applied to the average assets in the portfolio. 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 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. 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 both the three months ended March 31, 2019 and 2018, a portion of the distribution fee revenue recognized in the current 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. Portfolio Consulting and Other —The Company earns the majority of its portfolio consulting and other fees by (i) providing portfolio consulting services in connection with model-based strategy accounts, (ii) earning a licensing fee for the use of the Company's proprietary indexes and (iii) providing portfolio monitoring services related to a number of unit investment trusts. Revenue is earned pursuant to the terms of the underlying contracts and the fee schedules for these relationships vary based on the type of services the Company provides for each relationship. The majority of the Company's revenue from portfolio consulting and other is recognized over time and represents variable consideration, as fees are based on average assets under advisement 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 fee expense represents 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 costs and 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 (Rule 12b-1). The Company pays distribution fee expense based on the average daily net assets under management of certain share classes of certain of the funds. Shareholder servicing fee expense represents payments made to qualified intermediaries for shareholder account service and maintenance. These services are provided pursuant to written agreements with such qualified institutions. The Company pays shareholder servicing fee expense generally based on the average assets under management or the number of accounts being serviced. Intermediary assistance payments represent payments to qualified intermediaries for activities related to distribution, shareholder servicing and 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 or the number of accounts being serviced. Stock-based Compensation —The Company recognizes compensation expense for the grant-date fair value of awards of equity instruments to 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 represents the Company's best estimate of the effective tax rate expected to be applied to the full fiscal year. The calculation of tax liabilities involves dealing with uncertainties in the application of complex tax laws and regulations in a multitude of jurisdictions across the Company's global operations. A tax benefit from an uncertain tax position may be 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. 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 $(6,925,000) and $(7,323,000) at March 31, 2019 and December 31, 2018 , respectively. Gains or losses resulting from transactions denominated in currencies other than the U.S. dollar held by 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 —The Company reports all changes in comprehensive income in the condensed consolidated statements of comprehensive income. Comprehensive income includes net income or loss attributable to common stockholders and amounts attributable to foreign currency translation gain (loss), net of tax. Recently Issued Accounting Pronouncements —In January 2017, the FASB issued guidance to simplify the goodwill impairment test by removing the requirement to perform a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. This new guidance will be effective on January 1, 2020. The Company does not expect the adoption of the new guidance to have a material effect on its condensed consolidated financial statements and related disclosures.

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. If the asset or liability has a specified (contractual) term, the level 2 input must be observable for substantially the full term of the asset or liability. • 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. In determining the appropriate levels, the Company performed a detailed analysis of the assets and liabilities that are subject to ASC 820. The following table presents fair value measurements at March 31, 2019 (in thousands): Level 1 Level 2 Level 3 Investments Measured at NAV Investments Carried at Amortized Cost Total Cash equivalents 49,330 $ — $ — $ — $ — $ 49,330 Equity investments at fair value Common stocks 99,322 $ — $ — $ — $ — $ 99,322 Company-sponsored funds 5,417 — — — — 5,417 Limited partnership interests 1,407 — — 474 — 1,881 Preferred securities 1,224 119 — — — 1,343 Other — — — 122 — 122 Total $ 107,370 $ 119 $ — $ 596 $ — $ 108,085 Trading investments Fixed income $ — $ 29,158 $ — $ — $ — $ 29,158 Total $ — $ 29,158 $ — $ — $ — $ 29,158 Held-to-maturity investments Fixed income $ — $ — $ — $ — $ 49,797 $ 49,797 Total $ — $ — $ — $ — $ 49,797 $ 49,797 Equity method investments $ — $ — $ — $ 23 $ — $ 23 Total investments $ 107,370 $ 29,277 $ — $ 619 $ 49,797 $ 187,063 Derivatives - assets Commodity futures contracts $ 499 $ — $ — $ — $ — $ 499 Foreign exchange contracts — 114 — — — 114 Total $ 499 $ 114 $ — $ — $ — $ 613 Derivatives - liabilities Commodity futures contracts $ 411 $ — $ — $ — $ — $ 411 Commodity swap contracts — 2 — — — 2 Foreign exchange contracts — 127 — — — 127 Total $ 411 $ 129 $ — $ — $ — $ 540 The following table presents fair value measurements at December 31, 2018 (in thousands): Level 1 Level 2 Level 3 Investments Measured at NAV Investments Carried at Amortized Cost Total Cash equivalents $ 78,147 $ — $ — $ — $ — $ 78,147 Equity investments at fair value Common stocks $ 21,982 $ — $ — $ — $ — $ 21,982 Company-sponsored funds 9,456 — — — — 9,456 Limited partnership interests 1,056 — — 550 — 1,606 Preferred securities 30,448 3,193 — — — 33,641 Other — — — 110 — 110 Total $ 62,942 $ 3,193 $ — $ 660 $ — $ 66,795 Trading investments Fixed income $ — $ 108,363 $ — $ — $ — $ 108,363 Total $ — $ 108,363 $ — $ — $ — $ 108,363 Held-to-maturity investments Fixed income $ — $ — $ — $ — $ 49,748 $ 49,748 Total $ — $ — $ — $ — $ 49,748 $ 49,748 Equity method investments $ — $ — $ — $ 26 $ — $ 26 Total investments $ 62,942 $ 111,556 $ — $ 686 $ 49,748 $ 224,932 Derivatives - assets Commodity futures contracts $ 486 $ — $ — $ — $ — $ 486 Commodity swap contracts — 739 — — — 739 Total $ 486 $ 739 $ — $ — $ — $ 1,225 Derivatives - liabilities Commodity futures contracts $ 2,181 $ — $ — $ — $ — $ 2,181 Foreign exchange contracts — 205 — — — 205 Total $ 2,181 $ 205 $ — $ — $ — $ 2,386 Cash equivalents were comprised of investments in actively traded U.S. Treasury money market funds measured at NAV. Equity investments at fair value classified as level 2 were comprised of certain preferred securities with predominately equity-like characteristics whose fair values are 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 held within consolidated funds carried at amortized cost, which approximates fair value, corporate debt securities, as well as certain preferred securities with predominately debt-like characteristics. 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. Since these securities do not trade on a daily basis, the pricing services evaluate pricing applications and apply available information through processes such as yield curves, benchmarking of like securities, sector groupings, and matrix pricing, to prepare evaluations. 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 - 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, both of which are valued based on the NAVs of the underlying investments. At March 31, 2019 and December 31, 2018, 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 - the Company's partnership interest in a Company-sponsored limited partnership that invests in non-registered real estate funds, which approximated its fair value based on the fund's NAV. The Company's ownership in this limited partnership was approximately 0.2% at both March 31, 2019 and December 31, 2018. The Company's risk with respect to this investment is limited to its equity ownership and any uncollected management fees. At March 31, 2019 and December 31, 2018, the Company did not have the ability to redeem this investment. Held-to-maturity investments were comprised of U.S. Treasury securities, which were directly issued by the U.S. government, with original maturities of 6 to 24 months. These securities were purchased with the intent to hold to maturity and are 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 table are intended to permit reconciliation of the fair value hierarchy to the amounts presented on the consolidated statement of financial position. Commodity swap contracts classified as level 2 were valued based on the underlying futures contracts. Foreign currency exchange contracts classified as level 2 were valued based on the prevailing forward exchange rate. The following table summarizes the changes in level 3 limited partnership interests in trading investments measured at fair value on a recurring basis for the three months ended March 31, 2018 (in thousands): Balance at beginning of the period $ 605 Purchases / contributions — Sales / distributions (598 ) Realized gains (losses) (68 ) Unrealized gains (losses) 61 Transfers into (out of) level 3 — Balance at end of the period $ — Realized and unrealized gains (losses) in the above table were recorded as gain (loss) from investments—net in the Company's condensed consolidated statements of operations. 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. Foreign exchange contracts are valued based on the prevailing forward exchange rate, which is an input that is observable in active markets (level 2). 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 involves a significant degree of judgment, taking into consideration a combination of internal and external factors. Such investments 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.

Earnings Per Share [Abstract]
Earnings Per Share	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 using the treasury stock method by dividing net income attributable to common stockholders by the total weighted average shares of common stock outstanding and common stock equivalents. 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. Anti-dilutive common stock equivalents of approximately 4,700 and 4,600 shares were excluded from the computation for the three months ended March 31, 2019 and 2018, respectively. The following table reconciles income and share data used in the basic and diluted earnings per share computations for the periods presented (in thousands, except per share data): Three Months Ended 2019 2018 Net income $ 39,977 $ 28,924 Less: Net (income) loss attributable to redeemable noncontrolling interests (7,434 ) (1,338 ) Net income attributable to common stockholders $ 32,543 $ 27,586 Basic weighted average shares outstanding 47,146 46,683 Dilutive potential shares from restricted stock units 496 469 Diluted weighted average shares outstanding 47,642 47,152 Basic earnings per share attributable to common stockholders $ 0.69 $ 0.59 Diluted earnings per share attributable to common stockholders $ 0.68 $ 0.59

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The provision for income taxes includes U.S. federal, state, local and foreign taxes. The effective tax rate for the three months ended March 31, 2019 was approximately 24.2% , compared with 22.7% for the three months ended March 31, 2018 . The effective tax rate for both the three months ended March 31, 2019 and 2018 differed from the U.S. federal statutory rate of 21% primarily due to state, local and foreign taxes, partially offset by the tax effects related to the delivery of restricted stock units. 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 February 2018, the Financial Accounting Standards Board (FASB) issued new guidance allowing entities to reclassify certain tax effects related to the enactment of the Tax Cuts and Jobs Act (the Tax Act) from accumulated other comprehensive income (AOCI) to retained earnings. Prior to the issuance of the new guidance, a portion of the previously recognized deferred tax effects recorded in AOCI was "left stranded" in AOCI as the effect of remeasuring the deferred taxes using the reduced federal corporate income tax rate was required to be recorded through income. The new guidance allows these stranded tax effects to be reclassified from AOCI to retained earnings. The new guidance became effective on January 1, 2019 and the Company adopted the standard using the prospective application. The Company's adoption of the new standard did not have a material effect on its consolidated financial statements and related disclosures. In February 2016, the FASB issued guidance introducing a new lease model which requires lessees to recognize leases on-balance sheet and disclose key information about leasing arrangements. The new guidance establishes a right-of-use model (ROU) that requires a lessee to recognize an ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. This new guidance became effective on January 1, 2019 and the Company adopted the standard, along with certain allowable practical expedients, using the modified retrospective transition approach, which required the recasting of prior period amounts. Other than the Company's condensed consolidated statements of financial condition, the adoption of the new standard had no material impact on its condensed consolidated financial statements.
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. 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 funds for which the Company's ownership is less than 100%.
Cash and Cash Equivalents	Cash and Cash Equivalents —Cash and cash equivalents are on deposit with three major financial institutions and consist of 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 —Company-sponsored funds that are consolidated 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 cash equivalents balances at brokers/custodians and/or receivables and payables for unsettled securities transactions.
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, 2019 , the Company's investments were comprised of the following: • Equity investments at fair value, which includes securities held within the affiliated funds that the Company consolidates, individual 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 represent debt securities held within the affiliated funds that the Company consolidates and individual debt securities held directly for the purposes of establishing performance track records. • Held-to-maturity investments, which represent fixed income securities recorded at amortized cost. The Company periodically reviews held-to-maturity investments for other-than-temporary impairments (OTTI). If the Company believes an OTTI exists, an impairment charge will be recognized in the Company’s condensed consolidated statements of operations. • Equity method investments, which represent seed investments in which the Company owns between 20-50% of the outstanding voting interests in the affiliated fund 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 the affiliated investee fund 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 affiliated funds consolidated by the Company, enters into derivative contracts to gain exposure to the underlying commodities markets or to hedge market and credit risks of the underlying portfolios, including options, futures and swaps contracts. Gain 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. At March 31, 2019 , none of the outstanding derivative contracts were subject to a master netting agreement or other similar arrangement. Additionally, from time to time, the Company, including the affiliated funds consolidated by the Company, enters into foreign exchange contracts to 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 gains (losses)—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.
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. Leases —The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease 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 liabilities are recognized at commencement date based on the net present value of lease payments over the lease term. None of the Company’s lease agreements provide an implicit rate. As a result, the Company used an implied incremental borrowing rate based on the information available at 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 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.
Redeemable Noncontrolling Interests	Redeemable Noncontrolling Interests —Redeemable noncontrolling interests represent third-party interests in the affiliated funds that the Company consolidates. These interests are redeemable at the option of the investors and therefore are not treated as permanent equity. Redeemable noncontrolling interest is remeasured at redemption value which approximates the fair value at each reporting period.
Stock-based Compensation	Stock-based Compensation —The Company recognizes compensation expense for the grant-date fair value of awards of equity instruments to 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 represents the Company's best estimate of the effective tax rate expected to be applied to the full fiscal year. The calculation of tax liabilities involves dealing with uncertainties in the application of complex tax laws and regulations in a multitude of jurisdictions across the Company's global operations. A tax benefit from an uncertain tax position may be 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 $(6,925,000) and $(7,323,000) at March 31, 2019 and December 31, 2018 , respectively. Gains or losses resulting from transactions denominated in currencies other than the U.S. dollar held by 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 includes net income or loss attributable to common stockholders and amounts attributable to foreign currency translation gain (loss), net of tax.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements —In January 2017, the FASB issued guidance to simplify the goodwill impairment test by removing the requirement to perform a hypothetical purchase price allocation. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. This new guidance will be effective on January 1, 2020. The Company does not expect the adoption of the new guidance to have a material effect on its condensed consolidated financial statements and related disclosures.
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. Foreign exchange contracts are valued based on the prevailing forward exchange rate, which is an input that is observable in active markets (level 2). 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 involves a significant degree of judgment, taking into consideration a combination of internal and external factors. Such investments 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.
