Summary of Significant Accounti

Summary of Significant Accounting Policies	12 Months Ended

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Recently Adopted Accounting Pronouncements —In December 2019, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update 2019-12, Income Taxes (Topic 740): Simplifying the 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 consolidated financial statements and related disclosures. Accounting Estimates —The preparation of the 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 consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. Management believes the estimates used in preparing the consolidated financial statements are reasonable and prudent. Actual results could differ from those estimates. Reclassifications— The Company reclassified certain prior period amounts to conform with the current period presentation, primarily related to accrued employee benefits which were reclassified from other liabilities and accrued expenses to accrued compensation and benefits on the Company's consolidated statements of financial condition and cash flows. 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. 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. Subscriptions and redemptions or amendments to the governing documents of the respective entities could affect an entity's status as a VIE or the determination of the primary beneficiary. Limited partnerships and similar entities are determined to be a VIE when the Company is the general partner and the limited partners do not hold substantive kick-out or participation rights. The Company assesses whether it is the primary beneficiary of any VIEs identified by evaluating its economic interests in the entity held either directly by the Company and its affiliates or indirectly through employees. VIEs for which the Company is deemed to be the primary beneficiary are consolidated. Investments 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. 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 balances represent 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. The Company's investments are categorized as follows: • Equity investments at fair value, which generally represent listed equity securities held within the consolidated Company-sponsored funds, listed equity securities held directly for the purpose 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 purpose of establishing performance track records. • Held-to-maturity investments 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 December 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 in gain (loss) from investments—net in the Company's 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 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 in gain (loss) from investments—net in the Company's 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 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 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 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 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 which are included in operating lease right-of-use (ROU) assets and operating lease liabilities on the Company’s consolidated statements of financial condition. ROU assets represent the right to use an underlying asset for the lease term and lease liabilities represent obligations to make lease payments arising from the lease. Operating lease ROU assets and lease liabilities are recognized at commencement date based on the net present value of lease payments over the life of the lease. The majority of the Company’s lease agreements do not provide an implicit rate. As a result, the Company used its estimated 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 assets reflect any upfront lease payments made as well as lease incentives received. The lease terms may include options to extend or terminate the lease and these are factored into the determination of the ROU asset and lease liability at lease inception when and if it is reasonably certain that the Company will exercise that option. Lease expense for fixed lease payments is recognized on a straight-line basis over the lease term. The Company has certain lease agreements with non-lease components such as maintenance and executory costs, which are accounted for separately and not included in ROU assets. ROU assets are tested for impairment whenever changes in facts or circumstances indicate that the carrying amount of an asset may not be recoverable. Modification of a lease term would result in remeasurement of the lease liability and a corresponding adjustment to the ROU assets. 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 interests are 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 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. For all periods presented, a portion of the distribution fee revenue recognized in the period may relate to performance obligations satisfied (or partially satisfied) in prior periods. Service fee agreements include a single performance obligation as the services provided are not separately identifiable and are accounted for as a series satisfied over time using a time-based method (days elapsed). Additionally, distribution and service fees represent variable consideration, as fees are based on average assets under management which fluctuate daily. Distribution and Service Fee Expense —Distribution and service fee expense includes distribution fees, shareholder servicing fees and intermediary assistance payments. Distribution fees represent payments made to qualified intermediaries for (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 average daily net assets under management of certain share classes of certain of the funds. Shareholder servicing fees represent payments made to qualified intermediaries for shareholder account service and maintenance. These services are provided pursuant to written agreements with such qualified institutions. Shareholder servicing fees are generally based on average daily net assets under management. Intermediary assistance payments represent payments to qualified intermediaries for activities related to distribution, shareholder servicing as well as marketing and support of the Company's sponsored open-end funds and are incremental to those described above. Intermediary assistance payments are generally based on average daily net assets under management. Stock-based Compensation —The Company recognizes compensation expense for the grant-date fair value of restricted stock unit awards to certain employees. This expense is recognized over the period during which employees are required to provide service. Forfeitures are recorded as incurred. Any change to the key terms of an employee’s award subsequent to the grant date is evaluated and, if necessary, accounted for as a modification. If the modification results in the remeasurement of the fair value of the award, the remeasured compensation cost is recognized over the remaining service period. Income Taxes —The Company records the current and deferred tax consequences of all transactions that have been recognized in the consolidated financial statements in accordance with the provisions of the enacted tax laws. Deferred tax assets are recognized for temporary differences that will result in deductible amounts in future years at tax rates that are expected to apply in those years. 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 calculation of tax liabilities involves uncertainties in the application of complex tax laws and regulations across the Company's global operations. A tax benefit from an uncertain tax position is recognized when it is more likely than not that the position will be sustained upon examination, including resolution of any related appeals or litigation processes, on the basis of the technical merits. The Company records potential interest and penalties related to uncertain tax positions in the provision for income taxes in the consolidated statements of operations. Currency Translation and Transactions —Assets and liabilities of subsidiaries having non-U.S. dollar functional currencies are translated at exchange rates at the applicable consolidated statement of financial condition date. Revenue and expenses of such subsidiaries are translated at average exchange rates during the period. The gains or losses resulting from translating non-U.S. dollar functional currency into U.S. dollars are included in the Company's consolidated statements of comprehensive income. The cumulative translation adjustment was $(5.9) million, $(4.1) million and $(6.3) million as of December 31, 2021, 2020 and 2019, respectively, and was reported within accumulated other comprehensive income (loss) on the consolidated statements of financial condition. Gains or losses resulting from transactions denominated in currencies other than the U.S. dollar within certain foreign subsidiaries and gains and losses arising on revaluation of U.S. dollar-denominated assets and liabilities held by certain foreign subsidiaries are included in foreign currency gain (loss)-net in the Company’s consolidated statements of operations. Comprehensive Income —The Company reports all changes in comprehensive income in the 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).

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: December 31, 2021 (in thousands) Level 1 Level 2 Level 3 Investments Measured at NAV (1) Total Cash equivalents $ 104,591 $ — $ — $ — $ 104,591 Equity investments at fair value: Common stocks $ 126,301 $ 116 $ — $ — $ 126,417 Company-sponsored funds 103 — — — 103 Limited partnership interests 986 — — 1,816 2,802 Preferred securities 1,465 — — — 1,465 Other — — — 143 143 Total $ 128,855 $ 116 $ — $ 1,959 $ 130,930 Trading investments: Fixed income $ — $ 23,711 $ — $ — $ 23,711 Equity method investments $ — $ — $ — $ 13 $ 13 Total investments $ 128,855 $ 23,827 $ — $ 1,972 $ 154,654 Derivatives - assets: Total return swaps - commodities (2) $ — $ 481 $ — $ — $ 481 Forward contracts - foreign exchange — 209 — — 209 Total $ — $ 690 $ — $ — $ 690 Derivatives - liabilities: Total return swaps - commodities $ — $ 17 $ — $ — $ 17 Total return swaps - equities — 867 — — 867 Forward contracts - foreign exchange — 3 — — 3 Total $ — $ 887 $ — $ — $ 887 ________________________ (1) Comprised of certain investments measured at fair value using net asset value (NAV) as a practical expedient.

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 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 as follows: • Equity investments at fair value included: ◦ interests in private real estate funds held by the Company's consolidated 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). At December 31, 2021 and 2020, the Company did not have the ability to redeem the interests in private real estate funds held by the Company's consolidated funds. 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 interest in the Cohen & Steers Global Realty Partners III-TE, L.P. (GRP-TE) which 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 December 31, 2021 or 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 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 as a practical expedient and investments carried at amortized cost have not been classified in the fair value hierarchy. The amounts presented in the above tables are intended to permit reconciliation of the fair value hierarchy to the amounts presented on the consolidated statements of financial condition. 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 are valued no less than 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 ShareBasic earnings per share is calculated by dividing net income attributable to common stockholders by the weighted average shares outstanding. Diluted earnings per share is calculated by dividing net income attributable to common stockholders by the total weighted average shares of common stock outstanding and common stock equivalents determined using the treasury stock method. Common stock equivalents are comprised of dilutive potential shares from restricted stock unit awards and are excluded from the computation if their effect is anti-dilutive.

Share-based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation Amended and Restated Stock Incentive Plan The Amended and Restated Cohen & Steers, Inc. Stock Incentive Plan (the SIP) provides for the issuance of Restricted Stock Units (RSUs), stock options and other stock-based awards to eligible employees and directors. A total of 20.0 million shares of common stock may be granted under the SIP. The board of directors is authorized to increase the number of shares available for issuance under the SIP, subject to shareholder approval. At December 31, 2021, 18.0 million RSUs, representing the same amount of common stock, had been issued under the SIP. As of December 31, 2021, there was $65.2 million of compensation related to unamortized RSUs that had not yet been recognized in the consolidated statement of operations. The Company expects to recognize this expense over approximately the next three years. In January 2022, the Company granted approximately 634,000 RSUs under the SIP with a grant date fair value of $52.3 million, which generally vest over a four-year period. Restricted Stock Units Vested Restricted Stock Unit Grants The Company grants awards of vested RSUs to the non-management directors and certain employees of the Company pursuant to the SIP. Dividends declared on these awards are paid in cash. In connection with the grant of these vested RSUs, the Company recorded non-cash stock-based compensation expense of $2.1 million, $0.7 million and $0.6 million for the years ended December 31, 2021, 2020 and 2019, respectively. Unvested Restricted Stock Unit Grants From time to time, the Company grants awards of unvested RSUs to certain employees pursuant to the SIP. The fair value at the date of grant is expensed on a straight-line basis over the applicable service period, which is generally four years. Dividends declared by the Company are paid in additional RSUs which are subject to forfeiture until they are delivered. The dividend equivalent RSUs will generally vest and be delivered on the fourth anniversary of the original grant date. The Company recorded stock-based compensation expense, net of forfeitures, of $8.5 million, $4.6 million and $4.4 million for the years ended December 31, 2021, 2020 and 2019, respectively. Incentive Bonus Plans for Employees of the Company The Company has implemented a program for employees which, based upon compensation levels, automatically allocates a portion of their year-end bonuses in the form of unvested RSUs (Mandatory Program). The fair value at the date of grant of the RSUs under the Mandatory Program is expensed on a straight-line basis over the vesting period, which is generally four years. Dividends declared by the Company are paid in additional RSUs which are subject to forfeiture until they are delivered. The dividend equivalent RSUs will generally vest and be delivered on the fourth anniversary of the original grant date.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2021
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 the 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 consolidated financial statements and related disclosures.
Accounting Estimates	Accounting Estimates —The preparation of the 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 consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. Management believes the estimates used in preparing the consolidated financial statements are reasonable and prudent. Actual results could differ from those estimates.
Reclassifications	Reclassifications— The Company reclassified certain prior period amounts to conform with the current period presentation, primarily related to accrued employee benefits which were reclassified from other liabilities and accrued expenses to accrued compensation and benefits on the Company's consolidated statements of financial condition and cash flows.
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. 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. Subscriptions and redemptions or amendments to the governing documents of the respective entities could affect an entity's status as a VIE or the determination of the primary beneficiary. Limited partnerships and similar entities are determined to be a VIE when the Company is the general partner and the limited partners do not hold substantive kick-out or participation rights. The Company assesses whether it is the primary beneficiary of any VIEs identified by evaluating its economic interests in the entity held either directly by the Company and its affiliates or indirectly through employees. VIEs for which the Company is deemed to be the primary beneficiary are consolidated. Investments 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.
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 balances represent 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. The Company's investments are categorized as follows: • Equity investments at fair value, which generally represent listed equity securities held within the consolidated Company-sponsored funds, listed equity securities held directly for the purpose 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 purpose of establishing performance track records. • Held-to-maturity investments 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 December 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 in gain (loss) from investments—net in the Company's 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 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 in gain (loss) from investments—net in the Company's 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 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 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 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 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 which are included in operating lease right-of-use (ROU) assets and operating lease liabilities on the Company’s consolidated statements of financial condition. ROU assets represent the right to use an underlying asset for the lease term and lease liabilities represent obligations to make lease payments arising from the lease. Operating lease ROU assets and lease liabilities are recognized at commencement date based on the net present value of lease payments over the life of the lease. The majority of the Company’s lease agreements do not provide an implicit rate. As a result, the Company used its estimated 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 assets reflect any upfront lease payments made as well as lease incentives received. The lease terms may include options to extend or terminate the lease and these are factored into the determination of the ROU asset and lease liability at lease inception when and if it is reasonably certain that the Company will exercise that option. Lease expense for fixed lease payments is recognized on a straight-line basis over the lease term. The Company has certain lease agreements with non-lease components such as maintenance and executory costs, which are accounted for separately and not included in ROU assets. ROU assets are tested for impairment whenever changes in facts or circumstances indicate that the carrying amount of an asset may not be recoverable. Modification of a lease term would result in remeasurement of the lease liability and a corresponding adjustment to the ROU assets.
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 interests are 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	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 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. For all periods presented, a portion of the distribution fee revenue recognized in the period may relate to performance obligations satisfied (or partially satisfied) in prior periods. Service fee agreements include a single performance obligation as the services provided are not separately identifiable and are accounted for as a series satisfied over time using a time-based method (days elapsed). Additionally, distribution and service fees represent variable consideration, as fees are based on average assets under management which fluctuate daily.
Distribution and Service Fee Expense	Distribution and Service Fee Expense —Distribution and service fee expense includes distribution fees, shareholder servicing fees and intermediary assistance payments. Distribution fees represent payments made to qualified intermediaries for (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 average daily net assets under management of certain share classes of certain of the funds. Shareholder servicing fees represent payments made to qualified intermediaries for shareholder account service and maintenance. These services are provided pursuant to written agreements with such qualified institutions. Shareholder servicing fees are generally based on average daily net assets under management. Intermediary assistance payments represent payments to qualified intermediaries for activities related to distribution, shareholder servicing as well as marketing and support of the Company's sponsored open-end funds and are incremental to those described above. Intermediary assistance payments are generally based on average daily net assets under management.
Stock-based Compensation	Stock-based Compensation —The Company recognizes compensation expense for the grant-date fair value of restricted stock unit awards to certain employees. This expense is recognized over the period during which employees are required to provide service. Forfeitures are recorded as incurred. Any change to the key terms of an employee’s award subsequent to the grant date is evaluated and, if necessary, accounted for as a modification. If the modification results in the remeasurement of the fair value of the award, the remeasured compensation cost is recognized over the remaining service period.
Income Taxes	Income Taxes —The Company records the current and deferred tax consequences of all transactions that have been recognized in the consolidated financial statements in accordance with the provisions of the enacted tax laws. Deferred tax assets are recognized for temporary differences that will result in deductible amounts in future years at tax rates that are expected to apply in those years. 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 calculation of tax liabilities involves uncertainties in the application of complex tax laws and regulations across the Company's global operations. A tax benefit from an uncertain tax position is recognized when it is more likely than not that the position will be sustained upon examination, including resolution of any related appeals or litigation processes, on the basis of the technical merits. The Company records potential interest and penalties related to uncertain tax positions in the provision for income taxes in the consolidated statements of operations.
Currency Translation and Transactions	Currency Translation and Transactions —Assets and liabilities of subsidiaries having non-U.S. dollar functional currencies are translated at exchange rates at the applicable consolidated statement of financial condition date. Revenue and expenses of such subsidiaries are translated at average exchange rates during the period. The gains or losses resulting from translating non-U.S. dollar functional currency into U.S. dollars are included in the Company's consolidated statements of comprehensive income. The cumulative translation adjustment was $(5.9) million, $(4.1) million and $(6.3) million as of December 31, 2021, 2020 and 2019, respectively, and was reported within accumulated other comprehensive income (loss) on the consolidated statements of financial condition. Gains or losses resulting from transactions denominated in currencies other than the U.S. dollar within certain foreign subsidiaries and gains and losses arising on revaluation of U.S. dollar-denominated assets and liabilities held by certain foreign subsidiaries are included in foreign currency gain (loss)-net in the Company’s consolidated statements of operations.
Comprehensive Income	Comprehensive Income —The Company reports all changes in comprehensive income in the 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).
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 are valued no less than 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.
