Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Principles of Consolidation and Basis of Presentation The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"). The consolidated financial statements include the accounts of the Company, its subsidiaries and investment products that are consolidated. A voting interest entity ("VOE") is consolidated when the Company is considered to have a controlling financial interest, which is typically present when the Company owns a majority of the voting interest in an entity or otherwise has the power to govern the financial and operating policies of the entity. The Company evaluates any variable interest entity ("VIE") in which the Company has a variable interest for consolidation. 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) where as a group, the holders of the equity investment at risk do not possess any one of the following: (a) the power through voting or similar rights to direct the activities that most significantly impact the entity's economic performance, (b) the obligation to absorb expected losses or the right to receive expected residual returns of the entity, or (c) proportionate voting and economic interests and where substantially all of the entity's activities either involve or are conducted on behalf of an investor with disproportionately fewer voting rights. If an entity has any of these characteristics, it is considered a VIE and is required to be consolidated by its primary beneficiary. The primary beneficiary is the entity that has both the power to direct the activities that most significantly impact the VIE's economic performance and has the obligation to absorb losses of, or the right to receive benefits from, the VIE that could potentially be significant to the VIE. See Note 20 for additional information related to the consolidation of investment products. Intercompany accounts and transactions have been eliminated. Noncontrolling Interests Noncontrolling interests - CIP Noncontrolling interests - CIP represent third-party investments in the Company's CIP and are classified as redeemable noncontrolling interests on the Consolidated Balance Sheets because investors in those products are able to request withdrawal at any time. Noncontrolling interests - affiliate Noncontrolling interests - affiliate represent minority interests held in a consolidated affiliate. Minority interests held in the affiliate are subject to holder put rights and Company call rights at established multiples of earnings before interest, taxes, depreciation and amortization and, as such, are considered redeemable at other than fair value. The rights are exercisable at pre-established intervals or upon certain conditions, such as retirement. The put and call rights are not legally detachable or separately exercisable and are deemed to be embedded in the related noncontrolling interests. The Company, in purchasing affiliate equity, has the option to settle in cash or shares of the Company's common stock and is entitled to the cash flow associated with any purchased equity. These minority interests in the affiliate are recorded at estimated redemption value within redeemable noncontrolling interests on the Company's Consolidated Balance Sheets, and any changes in the estimated redemption value are recorded on the Consolidated Statements of Operations within noncontrolling interests. Use of Estimates The preparation of the consolidated financial statements 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 revenues 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. Segment Information Accounting Standards Codification ("ASC") 280, Segment Reporting, establishes disclosure requirements relating to operating segments in annual and interim financial statements. Operating segments are defined as components of an enterprise about which separate financial information is available that is regularly evaluated by the chief operating decision maker in deciding how to allocate resources to the segment and assess its performance. The Company's Chief Executive Officer is the Company's chief operating decision maker. The Company operates in one business segment, namely as an asset manager providing investment management and related services for individual and institutional clients. Although the Company provides disclosures regarding assets under management and other asset flows by product, the Company's determination that it operates in one business segment is based on the fact that the same investment professionals manage both retail and institutional products, operational resources support multiple products, such products have the same or similar regulatory framework and the Company's chief operating decision maker reviews the Company's financial performance on a consolidated level. Investment managers within the Company are generally not aligned with a specific product type. Cash and Cash Equivalents Cash and cash equivalents consist of cash in banks and money market fund investments. Restricted Cash The Company considers cash and cash equivalents of CIP and cash pledged or on deposit of CIP to be restricted as it is not available to the Company for its general operations. Investments Investment Securities - Fair Value Investment securities - fair value consist of investments in the Company's sponsored funds and separately managed accounts and are carried at fair value in accordance with ASC 320, Investments-Debt and Equity Securities ("ASC 320"), and Topic 321, Investments-Equity Securities ("ASC 321"). These securities are marked to market based on the respective publicly quoted net asset values of the funds or market prices of the equity securities or bonds. Transactions in these securities are recorded on a trade date basis. Any unrealized appreciation or depreciation on investment securities is reported on the Consolidated Statement of Operations within realized and unrealized gain (loss) on investments. Equity Method Investments Equity method investments consist of Company investments in noncontrolled entities, where the Company does not hold a controlling financial interest but has the ability to significantly influence operating and financial matters. Equity method investments are accounted for in accordance with ASC 323, Investments-Equity Method and Joint Ventures. Under the equity method of accounting, the Company's share of the noncontrolled entities' net income or loss is recorded in other income (expense), net on the Consolidated Statements of Operations. Distributions received reduce the Company's investment. The investment is evaluated for impairment if events or changes indicate that the carrying amount exceeds its fair value. If the carrying amount of an investment does exceed its fair value and the decline in fair value is deemed to be other-than-temporary, an impairment charge will be recorded. Non-qualified Retirement Plan Assets and Liabilities The Company has a non-qualified retirement plan (the "Excess Incentive Plan") that allows certain employees to voluntarily defer compensation. Assets held in trust, which are considered investment securities, are included in investments at fair value in accordance with ASC 820, Fair Value Measurement ("ASC 820"); the associated obligations to participants, which approximate the fair value of the associated assets, are included in other liabilities on the Consolidated Balance Sheets. (See Note 6 for additional information related to the Excess Incentive Plan.) Furniture, Equipment and Leasehold Improvements, Net Furniture, equipment and leasehold improvements are recorded at cost. Depreciation is computed using the straight-line method over the estimated useful lives of three to seven years for furniture and office equipment and three years for computer equipment and software. Leasehold improvements are depreciated over the shorter of the remaining estimated lives of the related leases or useful lives of the improvements. Major renewals or betterments are capitalized, and recurring repairs and maintenance are expensed as incurred. Leases The Company leases office space and equipment under various leasing arrangements. In accordance with ASC 842, Leases, the Company's leases are evaluated and classified as either financing leases or operating leases, as appropriate. The Company recognizes a lease liability and a corresponding right of use ("ROU") asset on the commencement date of any lease arrangement. The lease liability is initially measured at the present value of the future lease payments over the lease term using the rate implicit in the arrangement or, if not readily determinable, the Company's incremental borrowing rate. The Company determines its incremental borrowing rate through market sources, including relevant industry rates. A ROU asset is measured initially as the value of the lease liability plus initial direct costs and prepaid lease payments, and less lease incentives received. Lease expense is recognized on a straight-line basis over the lease term and is recorded within other operating expenses on the Consolidated Statement of Operations. Goodwill and Other Intangible Assets Goodwill represents the excess of the purchase price of business combinations over the identified assets and liabilities acquired. In accordance with ASC 350, Goodwill and Other Intangible Assets, goodwill is not amortized. The Company has a single reporting unit for the purpose of assessing potential impairments of goodwill. An impairment analysis of goodwill is performed annually or more frequently, if warranted by events or changes in circumstances affecting the Company's business. The Company follows Accounting Standards Update ("ASU") 2011-08, Testing Goodwill for Impairment, which provides the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, it is determined that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the two-step impairment test is unnecessary. The Company's 2023 and 2022 annual goodwill impairment analysis did not result in any impairment charges. Definite-lived intangible assets are comprised of certain investment management agreements, trade names, non-competition agreements and software. These assets are amortized on a straight-line basis over the estimated useful lives of such assets, which range from 4 to 16 years. Definite-lived intangible assets are evaluated for impairment on an ongoing basis whenever events or circumstances indicate that the carrying value of the definite-lived intangible asset may not be recoverable. The Company determines if impairment has occurred by comparing estimates of future undiscounted cash flows to the carrying value of assets. Assets are considered impaired, and an impairment is recorded, if the carrying value exceeds the expected future undiscounted cash flows. Indefinite-lived intangible assets are comprised of certain trade names and fund investment management agreements. These assets are tested for impairment annually or when events or changes in circumstances indicate the assets might be impaired. The Company follows ASU 2012-02, Testing Indefinite-Lived Intangible Assets for Impairment, which provides the option to perform a qualitative assessment of indefinite-lived intangible assets other than goodwill for impairment to determine if additional impairment testing is necessary. The Company's 2023 and 2022 annual indefinite-lived intangible assets impairment analysis did not result in any impairment charges. Contingent Consideration The Company periodically enters into contingent payment arrangements in connection with its business combinations or asset purchases. In contingent payment arrangements, the Company agrees to pay additional transaction consideration to the seller based on future performance. The Company estimates the value of estimated future payments of these potential future obligations at the time a business combination or asset purchase is consummated. Liabilities under contingent payment arrangements are recorded within contingent consideration on the Consolidated Balance Sheets. Contingent payment obligations related to business combinations are remeasured at fair value each reporting date using a simulation model with the assistance of an independent valuation firm and approved by management (level 3 fair value measurement). The change in fair value is recorded in the current period as a gain or loss. Gains and losses resulting from changes in the fair value of contingent payment obligations are reflected within change in fair value of contingent consideration on the Consolidated Statements of Operations. Contingent payment obligations related to our asset purchases, if estimable and probable of payment, are initially recorded at their estimated value and reviewed every reporting period for changes. Any changes to the estimated value are recorded as an update of the initial acquisition cost of the asset with a corresponding change to the estimated contingent payment obligation on the Consolidated Balance Sheets. Treasury Stock Treasury stock is accounted for under the cost method and is included as a deduction from equity on the Stockholders' Equity section of the Consolidated Balance Sheets. Upon any subsequent resale, the treasury stock account is reduced by the cost of such stock. Revenue Recognition The Company's revenues are recognized when a performance obligation is satisfied, which occurs when control of the services is transferred to customers. Investment management fees, distribution and service fees, and administration and shareholder service fees are generally calculated as a percentage of average net assets of the investment portfolios managed. The net asset values from which these fees are calculated are variable in nature and subject to factors outside of the Company's control, such as additional investments, withdrawals and market performance. Because of this, these fees are considered constrained until the end of the contractual measurement period (monthly or quarterly), which is when asset values are generally determinable. Investment Management Fees The Company provides investment management services pursuant to investment management agreements through its investment advisers (each an "Adviser"). Investment management services represent a series of distinct daily services that are performed over time. Fees earned on funds are based on each fund's average daily or weekly net assets and are generally calculated and received on a monthly basis. For funds managed by unaffiliated subadvisors, the Company records fees net of the subadvisory fees, as the Company is deemed to be the agent as it relates to the services performed by unaffiliated subadvisers, with the Company's performance obligation being to arrange for the provision of that service and not control the specified service before it is performed. Amounts paid to unaffiliated subadvisers for the years ended December 31, 2023, 2022 and 2021 were $54.7 million, $77.0 million and $115.5 million, respectively. Retail separate account fees are generally earned based on the end of the preceding or current quarter's asset values. Institutional account fees are generally earned based on an average of daily or month-end balances or the current quarter's asset values. Fees for structured finance products are generally earned at a contractual fee rate applied against the end of the preceding quarter par value of the total collateral being managed. Distribution and Service Fees Distribution and service fees are sales- and asset-based fees earned from open-end funds for marketing and distribution services. Depending on the fund type or share class, these fees primarily consist of an asset-based fee that is paid by the fund over a period of years to cover allowable sales and marketing expenses, or front-end sales charges that are based on a percentage of the offering price. Asset-based distribution and service fees are primarily earned as percentages of the average daily net assets value and are paid monthly pursuant to the terms of the respective distribution and service fee contracts. Distribution and service fees represent two performance obligations comprised of distribution and related shareholder servicing activities. Distribution services are generally satisfied upon the sale of a fund share. Shareholder servicing activities are generally services satisfied over time. The Company distributes its open-end funds through unaffiliated financial intermediaries that comprise national, regional and independent broker-dealers. These unaffiliated financial intermediaries provide distribution and shareholder service activities on behalf of the Company. The Company passes related distribution and service fees to these unaffiliated financial intermediaries for these services and considers itself the principal in these arrangements since it has control of the services prior to the services being transferred to the customer. These payments are classified within distribution and other asset-based expenses. Administration and Shareholder Service Fees The Company provides administrative fund services to its U.S. retail funds, and certain of its closed-end funds and shareholder services to its open-end funds. Administration and shareholder services are performed over time. The Company earns fees for these services, which are calculated and paid monthly, based on each fund's average daily or weekly net assets. Administrative fund services include: record keeping, preparing and filing documents required to comply with securities laws, legal administration and compliance services, customer service, supervision of the activities of the funds' service providers, tax services and treasury services. The Company also provides office space, equipment and personnel that may be necessary for managing and administering the business affairs of the funds. Shareholder services include maintaining shareholder accounts, processing shareholder transactions, preparing filings and performing necessary reporting. Other Income and Fees Other income and fees primarily represent fees related to other fee earning assets and contingent sales charges earned from investor redemptions of certain shares sold without a front-end sales charge. Stock-based Compensation The Company accounts for stock-based compensation expense in accordance with ASC 718, Compensation—Stock Compensation ("ASC 718"), which requires the measurement and recognition of compensation expense for share-based awards based on the estimated fair value on the date of grant. Restricted stock units ("RSUs") are stock awards that entitle the holder to receive shares of the Company's common stock as the award vests over time or when certain performance metrics are achieved. The fair value of each RSU award is based on the fair market value price on the date of grant unless it contains a performance metric that is considered a "market condition." Compensation expense for RSU awards is recognized ratably over the vesting period on a straight-line basis. The value of RSUs that contain a performance metric ("PSUs") is determined based on (i) the fair market value price on the date of grant, for awards that contain a performance metric that represents a "performance condition" in accordance with ASC 718 or (ii) the Monte Carlo simulation valuation model for awards that contain a "market condition" performance metric under ASC 718. Compensation expense for PSU awards with a performance condition is recorded each period based upon a probability assessment of the expected outcome of the performance metric with a final adjustment upon measurement at the end of the performance period. Compensation expense for PSU awards that contain a market condition is fixed at the date of grant and is not adjusted in future periods based upon the achievement of the market condition. Income Taxes The Company accounts for income taxes in accordance with ASC 740, Income Taxes ("ASC 740"), which requires recognition of the amount of taxes payable or refundable for the current year as well as deferred tax assets and liabilities for temporary differences between the tax basis of assets and liabilities and the reported amounts on the Consolidated Financial Statements. The Company's methodology for determining the realizability of deferred tax assets includes consideration of taxable income in prior carryback year(s), if carryback is permitted under the tax law, as well as consideration of the reversal of deferred tax liabilities that are in the same period and jurisdiction and are of the same character as the temporary differences that gave rise to the deferred tax assets. The Company's methodology also includes estimates of future taxable income from its operations as well as the expiration dates and amounts of carry-forwards related to net operating losses and capital losses. These estimates are projected through the life of the related deferred tax assets based on assumptions that the Company believes to be reasonable and consistent with demonstrated operating results. Unanticipated changes in future operating results may have a significant impact on the realization of deferred tax assets. Valuation allowances are provided when it is determined that it is more likely than not that the benefit of deferred tax assets will not be realized. Comprehensive Income The Company reports all changes in comprehensive income on the Consolidated Statements of Changes in Stockholders' Equity and the Consolidated Statements of Comprehensive Income. Comprehensive income includes net income (loss) and foreign currency translation adjustments (net of tax). Earnings (Loss) per Share Earnings (loss) per share ("EPS") is calculated in accordance with ASC 260, Earnings per Share. Basic EPS is computed by dividing net income (loss) attributable to Virtus Investment Partners, Inc. by the weighted-average number of common shares outstanding for the period, excluding dilution for potential common stock issuances. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock, including shares issuable upon the vesting of RSUs and stock option exercises using the treasury stock method, as determined under the if-converted method. Fair Value Measurements and Fair Value of Financial Instruments ASC 820, Fair Value Measurement, establishes a framework for measuring fair value and a valuation hierarchy based upon the transparency of inputs used in the valuation of an asset or liability. The Financial Accounting Standards Board (the "FASB") defines fair value as the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date. Classification within the hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The valuation hierarchy contains three levels as follows: Level 1—Unadjusted quoted prices for identical instruments in active markets. Level 1 assets and liabilities may include debt securities and equity securities that are traded in an active exchange market. 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 in active markets. Level 2 inputs may include observable market data such as closing market prices provided by independent pricing services after considering factors such as the yields or prices of comparable investments of comparable quality, coupon, maturity, call rights and other potential prepayments, terms and type, reported transactions, indications as to values from dealers and general market conditions. In addition, pricing services may determine the fair value of equity securities traded principally in foreign markets when it has been determined that there has been a significant trend in the U.S. equity markets or in index futures trading. Level 2 assets and liabilities may include debt and equity securities, purchased loans and over-the-counter derivative contracts whose fair value is determined using a pricing model without significant unobservable market data inputs. Level 3—Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable in active exchange markets. Recent Accounting Pronouncements New Accounting Standards Not Yet Implemented In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280). This standard updates reportable segment disclosure requirements, clarifies circumstances in which an entity can disclose multiple segment measures of profit or loss and provides new segment disclosure requirements for entities with a single reportable segment. This standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted, with the amendments to be applied retrospectively to all prior periods presented in the financial statements. The Company is in the process of evaluating the impact of adopting this standard and, at this time, does not anticipate it will have a material impact on its consolidated financial statements. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740). This standard updates income tax disclosure requirements by requiring disaggregated information about a reporting entity's effective tax rate reconciliation as well as information on income taxes paid. This standard is effective for fiscal years beginning after December 15, 2024. Early adoption is permitted. The Company is in the process of evaluating the impact of adopting this standard and, at this time, does not anticipate it will have a material impact on its consolidated financial statements.

The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"). The consolidated financial statements include the accounts of the Company, its subsidiaries and investment products that are consolidated. A voting interest entity ("VOE") is consolidated when the Company is considered to have a controlling financial interest, which is typically present when the Company owns a majority of the voting interest in an entity or otherwise has the power to govern the financial and operating policies of the entity.

The Company evaluates any variable interest entity ("VIE") in which the Company has a variable interest for consolidation. 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) where as a group, the holders of the equity investment at risk do not possess any one of the following: (a) the power through voting or similar rights to direct the activities that most significantly impact the entity's economic performance, (b) the obligation to absorb expected losses or the right to receive expected residual returns of the entity, or (c) proportionate voting and economic interests and where substantially all of the entity's activities either involve or are conducted on behalf of an investor with disproportionately fewer voting rights. If an entity has any of these characteristics, it is considered a VIE and is required to be consolidated by its primary beneficiary. The primary beneficiary is the entity that has both the power to direct the activities that most significantly impact the VIE's economic performance and has the obligation to absorb losses of, or the right to receive benefits from, the VIE that could potentially be significant to the VIE. See Note 20 for additional information related to the consolidation of investment products. Intercompany accounts and transactions have been eliminated.

Noncontrolling interests - affiliate represent minority interests held in a consolidated affiliate. Minority interests held in the affiliate are subject to holder put rights and Company call rights at established multiples of earnings before interest, taxes, depreciation and amortization and, as such, are considered redeemable at other than fair value. The rights are exercisable at pre-established intervals or upon certain conditions, such as retirement. The put and call rights are not legally detachable or separately exercisable and are deemed to be embedded in the related noncontrolling interests. The Company, in purchasing affiliate equity, has the option to settle in cash or shares of the Company's common stock and is entitled to the cash flow associated with any purchased equity. These minority interests in the affiliate are recorded at estimated redemption value within redeemable noncontrolling interests on the Company's Consolidated Balance Sheets, and any changes in the estimated redemption value are recorded on the Consolidated Statements of Operations within noncontrolling interests.

The preparation of the consolidated financial statements 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 revenues 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.

Accounting Standards Codification ("ASC") 280, Segment Reporting, establishes disclosure requirements relating to operating segments in annual and interim financial statements. Operating segments are defined as components of an enterprise about which separate financial information is available that is regularly evaluated by the chief operating decision maker in deciding how to allocate resources to the segment and assess its performance. The Company's Chief Executive Officer is the Company's chief operating decision maker. The Company operates in one business segment, namely as an asset manager providing investment management and related services for individual and institutional clients. Although the Company provides disclosures regarding assets under management and other asset flows by product, the Company's determination that it operates in one business segment is based on the fact that the same investment professionals manage both retail and institutional products, operational resources support multiple products, such products have the same or similar regulatory framework and the Company's chief operating decision maker reviews the Company's financial performance on a consolidated level. Investment managers within the Company are generally not aligned with a specific product type.

Investment securities - fair value consist of investments in the Company's sponsored funds and separately managed accounts and are carried at fair value in accordance with ASC 320, Investments-Debt and Equity Securities ("ASC 320"), and Topic 321, Investments-Equity Securities ("ASC 321"). These securities are marked to market based on the respective publicly quoted net asset values of the funds or market prices of the equity securities or bonds. Transactions in these securities are recorded on a trade date basis. Any unrealized appreciation or depreciation on investment securities is reported on the Consolidated Statement of Operations within realized and unrealized gain (loss) on investments.

Equity method investments consist of Company investments in noncontrolled entities, where the Company does not hold a controlling financial interest but has the ability to significantly influence operating and financial matters. Equity method investments are accounted for in accordance with ASC 323, Investments-Equity Method and Joint Ventures. Under the equity method of accounting, the Company's share of the noncontrolled entities' net income or loss is recorded in other income (expense), net on the Consolidated Statements of Operations. Distributions received reduce the Company's investment. The investment is evaluated for impairment if events or changes indicate that the carrying amount exceeds its fair value. If the carrying amount of an investment does exceed its fair value and the decline in fair value is deemed to be other-than-temporary, an impairment charge will be recorded.

The Company has a non-qualified retirement plan (the "Excess Incentive Plan") that allows certain employees to voluntarily defer compensation. Assets held in trust, which are considered investment securities, are included in investments at fair value in accordance with ASC 820, Fair Value Measurement ("ASC 820"); the associated obligations to participants, which approximate the fair value of the associated assets, are included in other liabilities on the Consolidated Balance Sheets. (See Note 6 for additional information related to the Excess Incentive Plan.)

Furniture, equipment and leasehold improvements are recorded at cost. Depreciation is computed using the straight-line method over the estimated useful lives of three to seven years for furniture and office equipment and three years for computer equipment and software. Leasehold improvements are depreciated over the shorter of the remaining estimated lives of the related leases or useful lives of the improvements. Major renewals or betterments are capitalized, and recurring repairs and maintenance are expensed as incurred.

The Company leases office space and equipment under various leasing arrangements. In accordance with ASC 842, Leases, the Company's leases are evaluated and classified as either financing leases or operating leases, as appropriate. The Company recognizes a lease liability and a corresponding right of use ("ROU") asset on the commencement date of any lease arrangement. The lease liability is initially measured at the present value of the future lease payments over the lease term using the rate implicit in the arrangement or, if not readily determinable, the Company's incremental borrowing rate. The Company determines its incremental borrowing rate through market sources, including relevant industry rates. A ROU asset is measured initially as the value of the lease liability plus initial direct costs and prepaid lease payments, and less lease incentives received. Lease expense is recognized on a straight-line basis over the lease term and is recorded within other operating expenses on the Consolidated Statement of Operations.

Goodwill represents the excess of the purchase price of business combinations over the identified assets and liabilities acquired. In accordance with ASC 350, Goodwill and Other Intangible Assets, goodwill is not amortized. The Company has a single reporting unit for the purpose of assessing potential impairments of goodwill. An impairment analysis of goodwill is performed annually or more frequently, if warranted by events or changes in circumstances affecting the Company's business. The Company follows Accounting Standards Update ("ASU") 2011-08, Testing Goodwill for Impairment, which provides the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, it is determined that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the two-step impairment test is unnecessary. The Company's 2023 and 2022 annual goodwill impairment analysis did not result in any impairment charges.

Definite-lived intangible assets are comprised of certain investment management agreements, trade names, non-competition agreements and software. These assets are amortized on a straight-line basis over the estimated useful lives of such assets, which range from 4 to 16 years. Definite-lived intangible assets are evaluated for impairment on an ongoing basis whenever events or circumstances indicate that the carrying value of the definite-lived intangible asset may not be recoverable. The Company determines if impairment has occurred by comparing estimates of future undiscounted cash flows to the carrying value of assets. Assets are considered impaired, and an impairment is recorded, if the carrying value exceeds the expected future undiscounted cash flows.

Indefinite-lived intangible assets are comprised of certain trade names and fund investment management agreements. These assets are tested for impairment annually or when events or changes in circumstances indicate the assets might be impaired. The Company follows ASU 2012-02, Testing Indefinite-Lived Intangible Assets for Impairment, which provides the option to perform a qualitative assessment of indefinite-lived intangible assets other than goodwill for impairment to determine if additional impairment testing is necessary. The Company's 2023 and 2022 annual indefinite-lived intangible assets impairment analysis did not result in any impairment charges.

The Company periodically enters into contingent payment arrangements in connection with its business combinations or asset purchases. In contingent payment arrangements, the Company agrees to pay additional transaction consideration to the seller based on future performance. The Company estimates the value of estimated future payments of these potential future obligations at the time a business combination or asset purchase is consummated. Liabilities under contingent payment arrangements are recorded within contingent consideration on the Consolidated Balance Sheets.

Contingent payment obligations related to business combinations are remeasured at fair value each reporting date using a simulation model with the assistance of an independent valuation firm and approved by management (level 3 fair value measurement). The change in fair value is recorded in the current period as a gain or loss. Gains and losses resulting

Contingent payment obligations related to our asset purchases, if estimable and probable of payment, are initially recorded at their estimated value and reviewed every reporting period for changes. Any changes to the estimated value are recorded as an update of the initial acquisition cost of the asset with a corresponding change to the estimated contingent payment obligation on the Consolidated Balance Sheets.

The Company's revenues are recognized when a performance obligation is satisfied, which occurs when control of the services is transferred to customers. Investment management fees, distribution and service fees, and administration and shareholder service fees are generally calculated as a percentage of average net assets of the investment portfolios managed. The net asset values from which these fees are calculated are variable in nature and subject to factors outside of the Company's control, such as additional investments, withdrawals and market performance. Because of this, these fees are considered constrained until the end of the contractual measurement period (monthly or quarterly), which is when asset values are generally determinable.

The Company provides investment management services pursuant to investment management agreements through its investment advisers (each an "Adviser"). Investment management services represent a series of distinct daily services that are performed over time. Fees earned on funds are based on each fund's average daily or weekly net assets and are generally calculated and received on a monthly basis. For funds managed by unaffiliated subadvisors, the Company records fees net of the subadvisory fees, as the Company is deemed to be the agent as it relates to the services performed by unaffiliated subadvisers, with the Company's performance obligation being to arrange for the provision of that service and not control the specified service before it is performed. Amounts paid to unaffiliated subadvisers for the years ended December 31, 2023, 2022 and 2021 were $54.7 million, $77.0 million and $115.5 million, respectively.

Retail separate account fees are generally earned based on the end of the preceding or current quarter's asset values. Institutional account fees are generally earned based on an average of daily or month-end balances or the current quarter's asset values. Fees for structured finance products are generally earned at a contractual fee rate applied against the end of the preceding quarter par value of the total collateral being managed.

Distribution and service fees are sales- and asset-based fees earned from open-end funds for marketing and distribution services. Depending on the fund type or share class, these fees primarily consist of an asset-based fee that is paid by the fund over a period of years to cover allowable sales and marketing expenses, or front-end sales charges that are based on a percentage of the offering price. Asset-based distribution and service fees are primarily earned as percentages of the average daily net assets value and are paid monthly pursuant to the terms of the respective distribution and service fee contracts.

Distribution and service fees represent two performance obligations comprised of distribution and related shareholder servicing activities. Distribution services are generally satisfied upon the sale of a fund share. Shareholder servicing activities are generally services satisfied over time.

The Company distributes its open-end funds through unaffiliated financial intermediaries that comprise national, regional and independent broker-dealers. These unaffiliated financial intermediaries provide distribution and shareholder service activities on behalf of the Company. The Company passes related distribution and service fees to these unaffiliated financial intermediaries for these services and considers itself the principal in these arrangements since it has control of the services prior to the services being transferred to the customer. These payments are classified within distribution and other asset-based expenses.

The Company provides administrative fund services to its U.S. retail funds, and certain of its closed-end funds and shareholder services to its open-end funds. Administration and shareholder services are performed over time. The Company earns fees for these services, which are calculated and paid monthly, based on each fund's average daily or weekly net assets. Administrative fund services include: record keeping, preparing and filing documents required to comply with securities laws, legal administration and compliance services, customer service, supervision of the activities of the funds' service providers, tax services and treasury services. The Company also provides office space, equipment and personnel that may be necessary for managing and administering the business affairs of the funds. Shareholder services include maintaining shareholder accounts, processing shareholder transactions, preparing filings and performing necessary reporting.

Restricted stock units ("RSUs") are stock awards that entitle the holder to receive shares of the Company's common stock as the award vests over time or when certain performance metrics are achieved. The fair value of each RSU award is based on the fair market value price on the date of grant unless it contains a performance metric that is considered a "market condition." Compensation expense for RSU awards is recognized ratably over the vesting period on a straight-line basis. The value of RSUs that contain a performance metric ("PSUs") is determined based on (i) the fair market value price on the date of grant, for awards that contain a performance metric that represents a "performance condition" in accordance with ASC 718 or (ii) the Monte Carlo simulation valuation model for awards that contain a "market condition" performance metric under ASC 718. Compensation expense for PSU awards with a performance condition is recorded each period based upon a probability assessment of the expected outcome of the performance metric with a final adjustment upon measurement at the end of the performance period. Compensation expense for PSU awards that contain a market condition is fixed at the date of grant and is not adjusted in future periods based upon the achievement of the market condition.

The Company accounts for income taxes in accordance with ASC 740, Income Taxes ("ASC 740"), which requires recognition of the amount of taxes payable or refundable for the current year as well as deferred tax assets and liabilities for temporary differences between the tax basis of assets and liabilities and the reported amounts on the Consolidated Financial Statements.

The Company's methodology for determining the realizability of deferred tax assets includes consideration of taxable income in prior carryback year(s), if carryback is permitted under the tax law, as well as consideration of the reversal of deferred tax liabilities that are in the same period and jurisdiction and are of the same character as the temporary differences that gave rise to the deferred tax assets. The Company's methodology also includes estimates of future taxable income from its operations as well as the expiration dates and amounts of carry-forwards related to net operating losses and capital losses. These estimates are projected through the life of the related deferred tax assets based on assumptions that the Company believes to be reasonable and consistent with demonstrated operating results. Unanticipated changes in future operating results may have a significant impact on the realization of deferred tax assets. Valuation allowances are provided when it is determined that it is more likely than not that the benefit of deferred tax assets will not be realized.

Earnings (loss) per share ("EPS") is calculated in accordance with ASC 260, Earnings per Share. Basic EPS is computed by dividing net income (loss) attributable to Virtus Investment Partners, Inc. by the weighted-average number of common shares outstanding for the period, excluding dilution for potential common stock issuances. Diluted EPS reflects the potential

ASC 820, Fair Value Measurement, establishes a framework for measuring fair value and a valuation hierarchy based upon the transparency of inputs used in the valuation of an asset or liability. The Financial Accounting Standards Board (the "FASB") defines fair value as the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date. Classification within the hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The valuation hierarchy contains three levels as follows:

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 in active markets. Level 2 inputs may include observable market data such as closing market prices provided by independent pricing services after considering factors such as the yields or prices of comparable investments of comparable quality, coupon, maturity, call rights and other potential prepayments, terms and type, reported transactions, indications as to values from dealers and general market conditions. In addition, pricing services may determine the fair value of equity securities traded principally in foreign markets when it has been determined that there has been a significant trend in the U.S. equity markets or in index futures trading. Level 2 assets and liabilities may include debt and equity securities, purchased loans and over-the-counter derivative contracts whose fair value is determined using a pricing model without significant unobservable market data inputs.

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280). This standard updates reportable segment disclosure requirements, clarifies circumstances in which an entity can disclose multiple segment measures of profit or loss and provides new segment disclosure requirements for entities with a single reportable segment. This standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted, with the amendments to be applied retrospectively to all prior periods presented in the financial statements. The Company is in the process of evaluating the impact of adopting this standard and, at this time, does not anticipate it will have a material impact on its consolidated financial statements.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740). This standard updates income tax disclosure requirements by requiring disaggregated information about a reporting entity's effective tax rate reconciliation as well as information on income taxes paid. This standard is effective for fiscal years beginning after December 15, 2024. Early adoption is permitted. The Company is in the process of evaluating the impact of adopting this standard and, at this time, does not anticipate it will have a material impact on its consolidated financial statements.
