Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Critical Accounting Policies The Company's critical accounting policies and estimates are disclosed in its Annual Report on Form 10-K for the year ended December 31, 2020. The Company believes that the disclosures herein are adequate so that the information presented is not misleading; however, these financial statements should be read in conjunction with the financial statements and the notes thereto in the Company's Annual Report on Form 10-K for the year ended December 31, 2020. The financial data for the interim periods may not necessarily be indicative of results for future interim periods or for the full year. Basis of Presentation The accompanying unaudited consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and related rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) for interim financial reporting and include all adjustments, consisting only of normal recurring adjustments which are, in the opinion of management, necessary for a fair statement of the results for the interim period. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates or assumptions that affect the reported amounts and disclosures in the consolidated financial statements. Actual results could differ from these estimates or assumptions. Principles of Consolidation The Company consolidates all majority-owned subsidiaries. As of September 30, 2021, Manning & Napier holds an economic interest of approximately 97.7% in Manning & Napier Group and, as managing member, controls all of the business and affairs of Manning & Napier Group. As a result, the Company consolidates the financial results of Manning & Napier Group and records a noncontrolling interest on its consolidated statements of financial condition with respect to the remaining economic interest in Manning & Napier Group held by M&N Group Holdings. All material intercompany transactions have been eliminated in consolidation. In accordance with Accounting Standards Update ("ASU") 2015-02, Consolidation (Topic 810) – Amendments to the Consolidation Analysis , the determination of whether a company is required to consolidate an entity is based on, among other things, an entity’s purpose and design, a company’s ability to direct the activities of the entity that most significantly impact the entity’s economic performance, and whether a company is obligated to absorb losses or receive benefits that could potentially be significant to the entity. The standard also requires ongoing assessments of whether a company is the primary beneficiary of a variable interest entity (“VIE”). When utilizing the voting interest entity ("VOE") model, controlling financial interest is generally defined as majority ownership of voting interests. The Company provides seed capital to its investment teams to develop new strategies and services for its clients. The original seed investment may be held in a separately managed account, comprised solely of the Company's investments or within a mutual fund, where the Company's investments may represent all or only a portion of the total equity investment in the mutual fund. Pursuant to U.S. GAAP, the Company evaluates its investments in mutual funds on a regular basis and consolidates such mutual funds for which it holds a controlling financial interest. When no longer deemed to hold a controlling financial interest, the Company would deconsolidate the fund and classify the remaining investment as either an equity method investment, equity investments, at fair value, or as trading securities, as applicable. As of September 30, 2021 and December 31, 2020, the Company did not have investments classified as an equity method investment. The Company serves as the investment adviser for Manning & Napier Fund, Inc. series of mutual funds (the “Fund”), Exeter Trust Company Collective Investment Trusts (“CIT”) and Rainier Multiple Investment Trust. The Fund, CIT and Rainier Multiple Investment Trust are legal entities, the business and affairs of which are managed by their respective boards of directors. As a result, each of these entities is a VOE. The Company holds, in limited cases, direct investments in a mutual fund (which are made on the same terms as are available to other investors) and consolidates each of these entities where it has a controlling financial interest or a majority voting interest. The Company's investments in the Fund amounted to approximately $2.0 million as of September 30, 2021 and $1.0 million as of December 31, 2020. As of September 30, 2021 and December 31, 2020, the Company did not have a controlling financial interest in any mutual fund. Revenue Investment Management: Investment management fees are computed as a percentage of assets under management ("AUM"). The Company's performance obligation is a series of services that form part of a single performance obligation satisfied over time. Separately managed accounts are paid in advance, typically for a semi-annual or quarterly period, or in arrears, typically for a monthly or quarterly period. When investment management fees are paid in advance, the Company defers the revenue as a contract liability and recognizes it over the applicable period. When investment management fees are paid in arrears, the Company estimates revenue and records a contract asset (accrued accounts receivable) based on AUM as of the most recent month end date. Mutual funds and collective investment trust investment management revenue is calculated and earned daily based on AUM. Revenue is presented net of cash rebates and fees waived pursuant to contractual expense limitations of the funds. The Company also has agreements with third parties who provide recordkeeping and administrative services for employee benefit plans participating in the collective investment trusts. The Company is acting as an agent on behalf of the employee benefit plan sponsors, therefore, investment management revenue is recorded net of fees paid to third party service providers. Distribution and shareholder servicing: The Company receives distribution and servicing fees for providing services to its affiliated mutual funds. Revenue is computed and earned daily based on a percentage of AUM. The performance obligation is a series of services that form part of a single performance obligation satisfied over time. The Company has agreements with third parties who provide distribution and administrative services for its mutual funds. The agreements are evaluated to determine whether revenue should be reported gross or net of payments to third-party service providers. The Company controls the services provided and acts as a principal in the relationship. Therefore, distribution and shareholder servicing revenue is recorded gross of fees paid to third parties. Custodial services: Custodial service fees are calculated as a percentage of the client’s market value with additional fees charged for certain transactions. For the safeguarding and administrative services that are subject to a percentage of market value fee, the Company's performance obligation is a series of services that form part of a single performance obligation satisfied over time. Revenue for transactions assigned a stand-alone selling price is recognized in the period in which the transaction is executed. Custodial service fees are billed monthly in arrears. The Company has agreements with third parties who provide safeguarding, recordkeeping and administrative services for their clients. The Company controls the services provided and acts as a principal in the relationship. Therefore, custodial service revenue is recorded gross of fees paid to third parties. Cash and Cash Equivalents The Company generally considers all highly liquid investments with original maturities of three months or less to be cash equivalents. Cash and cash equivalents are primarily held in operating accounts at major financial institutions and also in money market securities. Cash equivalents are stated at cost, which approximates market value due to the short-term maturity of these investments. The fair value of cash equivalents has been classified as Level 1 in accordance with the fair value hierarchy. Investment Securities Investment securities are classified as either equity investments, trading, equity method investments or available-for-sale and are carried at fair value. Fair value is determined based on quoted market prices in active markets for identical or similar instruments. Investment securities classified as equity investments, at fair value consist of equity securities and investments in mutual funds for which the Company provides advisory services. Realized and unrealized gains and losses on equity investments, at fair value or trading securities, as applicable, are recorded in net gains (losses) on investments in the consolidated statements of operations. Investment securities classified as available-for-sale consist of U.S. Treasury notes and corporate bonds. Unrealized gains and losses on available-for-sale securities are excluded from earnings and are reported, net of deferred income tax, as a separate component of accumulated other comprehensive income in shareholders’ equity until realized. The Company periodically reviews each individual security position that has an unrealized loss, or impairment, to determine if that impairment is other-than-temporary. If impairment is determined to be other-than-temporary, the carrying value of the security will be written down to fair value and the loss will be recognized in earnings. Realized gains and losses on sales of available-for-sale securities are computed on a specific identification basis and are recorded in net gains (losses) on investments in the consolidated statements of operations. Property, Equipment, Software and Depreciation Property and equipment is presented net of accumulated depreciation of approximately $12.0 million and $12.6 million as of September 30, 2021 and December 31, 2020, respectively. Capitalized implementation costs for hosting arrangements are included within prepaid expenses and other assets on the Company's statements of financial condition and totaled approximately $6.7 million and $5.3 million, net of accumulated amortization, as of September 30, 2021 and December 31, 2020, respectively. Goodwill and Intangible Assets Goodwill represents the excess cost over the fair value of the identifiable net assets of acquired companies. Identifiable intangible assets generally represent the cost of client relationships and investment management agreements acquired as well as trademarks. Goodwill and indefinite-lived assets are tested for impairment annually or more frequently if events or circumstances indicate that the carrying value may not be recoverable. Intangible assets subject to amortization are tested for impairment whenever events or circumstances indicate that the carrying value may not be recoverable. Goodwill and intangible assets require significant management estimate and judgment, including the valuation and expected life determination in connection with the initial purchase price allocation and the ongoing evaluation for impairment. Leases The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use ("ROU") assets, accrued expenses and other liabilities and operating lease liabilities, non-current on its consolidated statements of financial condition. Finance leases are included in other long-term assets, accrued expenses and other liabilities, and other long-term liabilities on its consolidated statements of financial condition. ROU assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. Operating lease ROU assets and lease liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the Company's leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The incremental borrowing rate, for each identified lease, is the rate of interest that the Company would have to pay to borrow on a collateralized basis over a similar term. The operating lease ROU asset is reduced for any lease incentives. The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain that it will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which are combined for all classes of underlying assets. Treasury Stock On February 3, 2021, the Board of Directors approved a share repurchase program authorizing the Company to purchase up to $10.0 million of Manning & Napier Inc. Class A common shares through December 31, 2021. As of September 30, 2021, the Company had purchased 749,005 shares of Class A common stock for an aggregate price of approximately $5.7 million. Treasury stock is accounted for under the cost method and is included as a deduction from equity in the Shareholders' Equity section of the consolidated statements of financial condition. Upon any subsequent retirement or resale, the treasury stock account is reduced by the cost of such stock. Operating Segments The Company operates in one segment, the investment management industry. Recent Accounting Pronouncements In December 2019, the Financial Accounting Standards Board ("FASB") issued ASU 2019-12, Simplifying the Accounting for Income Taxes , which is intended to simplify various aspects of the income tax accounting guidance, including interim-period accounting for enacted changes in the tax law. ASU 2019-12 is effective for public business entities for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years, and early adoption is permitted. The adoption of this ASU as of January 1, 2021 did not have a material impact on the Company's consolidated financial statements.

Accounts receivable balances do not include an allowance for doubtful accounts nor has any significant bad debt expense attributable to accounts receivable been recorded during the three and nine months ended September 30, 2021 or 2020. Advisory and Distribution Agreements The Company earns investment advisory fees, distribution fees and administrative service fees under agreements with affiliated mutual funds and collective investment trusts. Fees earned for advisory and distribution services provided were approximately $11.1 million and $31.6 million for the three and nine months ended September 30, 2021, respectively, and approximately $9.3 million and $26.7 million for the three and nine months ended September 30, 2020, respectively, which represents greater than 25% of revenue in each period. The following provides amounts due from affiliated mutual funds and collective investment trusts reported within accounts receivable in the consolidated statements of financial condition as of September 30, 2021 and December 31, 2020: September 30, 2021 December 31, 2020 (in thousands) Affiliated mutual funds $ 3,492 $ 3,275 Affiliated collective investment trusts 1,397 1,325 Accounts receivable - affiliated mutual funds and collective investment trusts $ 4,889 $ 4,600 Contract assets and liabilities Accrued accounts receivable : Accrued accounts receivable represents the Company's contract asset for revenue that has been recognized in advance of billing separately managed account contracts.

Noncontrolling Interest [Abstract]
Noncontrolling Interests	Noncontrolling Interests Manning & Napier holds an economic interest of approximately 97.7% in Manning & Napier Group, and as managing member controls all of the business and affairs of Manning & Napier Group. As a result, the Company consolidates the financial results of Manning & Napier Group and records a noncontrolling interest on its consolidated statements of financial condition with respect to the remaining approximately 2.3% economic interest in Manning & Napier Group held by M&N Group Holdings. Net income attributable to noncontrolling interests on the statements of operations represents the portion of earnings attributable to the economic interest in Manning & Napier Group held by the noncontrolling interests. The following table provides a reconciliation from “Income before provision for (benefit from) income taxes” to “Net income attributable to Manning & Napier, Inc.”: Three months ended September 30, Nine months ended September 30, 2021 2020 2021 2020 (in thousands) Income before provision for (benefit from) income taxes $ 9,233 $ 4,805 $ 23,926 $ 8,157 Less: income (loss) before provision for (benefit from) income taxes of Manning & Napier, Inc.

(2) Income before provision for (benefit from) income taxes is allocated to the controlling interest based on the percentage of units of Manning & Napier Group held by Manning & Napier, Inc. The amount represents the Company's weighted ownership of Manning & Napier Group's income for the respective periods. (3) The consolidated provision for (benefit from) income taxes is equal to the sum of (i) the provision for (benefit from) income taxes for entities other than Manning & Napier, Inc. and (ii) the provision for (benefit from) income taxes of Manning & Napier, Inc. which includes all U.S. federal and state income taxes. The consolidated provision for (benefit from) income taxes was a provision of $2.5 million and $1.7 million for the three months ended September 30, 2021 and 2020, respectively, and a provision of $4.5 million and benefit of less than $0.1 million for the nine months ended September 30, 2021 and 2020, respectively. As of September 30, 2021, a total of 428,812 units of Manning & Napier Group were held by the noncontrolling interests. Pursuant to the terms of the exchange agreement entered into at the time of the Company's initial public offering ("Exchange Agreement"), such units may be tendered for exchange or redemption. For any units exchanged, the Company may (i) pay an amount of cash equal to the number of tendered units multiplied by the value of one share of the Company's Class A common stock less a market discount and expected expenses, or, at the Company's election, (ii) issue shares of the Company's Class A common stock on a one-for-one basis, subject to customary adjustments. As the Company receives units of Manning & Napier Group that are exchanged, the Company's ownership of Manning & Napier Group will increase. On March 15, 2021, the Company received notice that 1,592,969 of Class A units of Manning & Napier Group were tendered for redemption or exchange. The independent directors, on behalf of the Company, decided that such exchange would be settled in 1,592,969 shares of unregistered Class A common stock of the Company. The Company completed the exchange on June 30, 2021 and as a result, Manning & Napier acquired an equivalent number of Class A units of Manning & Napier Group and its ownership of Manning & Napier Group increased from 89.0% to 97.7%. During the nine months ended September 30, 2021, Class A common stock was issued under the Company's 2011 Equity Compensation Plan (the "Equity Plan") for which Manning & Napier, Inc. acquired an equivalent number of Class A units of Manning & Napier Group. The following is the impact to the Company's equity ownership interest in Manning & Napier Group for the nine months ended September 30, 2021: Manning & Napier Group Class A Units Held Manning & Napier Total Manning & Napier Ownership % As of December 31, 2020 15,783,638 2,021,781 17,805,419 88.6% Class A Units issued 624,323 — 624,323 0.4% Class A Units exchanged 1,592,969 (1,592,969) — 8.7% As of September 30, 2021 18,000,930 428,812 18,429,742 97.7% Manning & Napier Inc., as managing member, controls all of the business and affairs of Manning & Napier Group. Since the Company continues to have a controlling interest in Manning & Napier Group, the aforementioned changes in ownership of Manning & Napier Group were accounted for as equity transactions under ASC Topic 810, Consolidation . Additional paid-in capital and noncontrolling interests in the consolidated statements of financial position are adjusted to reallocate the Company's historical equity to reflect the change in ownership of Manning & Napier Group. As a result of the completion of the exchange on June 30, 2021 and Manning & Napier Group's election under Section 754 of the Internal Revenue Code ("IRC"), the Company expects to benefit from future depreciation and amortization deductions resulting from increases in the tax basis of tangible and intangible assets of Manning & Napier Group. Those deductions allocated to the Company will be taken into account in reporting the Company's taxable income resulting in the recognition of a deferred tax asset. Manning & Napier and the holders of Manning & Napier Group are party to a tax receivable agreement ("TRA"), pursuant to which Manning & Napier is required to pay to such holders 85% of the applicable cash savings, if any, in U.S. federal, state, local and foreign income tax that Manning & Napier actually realizes, or is deemed to realize in certain circumstances, as a result of (i) certain tax attributes of their units sold to Manning & Napier or exchanged (for shares of Class A common stock) and that are created as a result of the sales or exchanges and payments under the TRA and (ii) tax benefits related to imputed interest. Accordingly, as a result of the completion of the exchange on June 30, 2021, deferred tax assets, amounts payable under the tax receivable agreement and additional paid-in capital increased by approximately $1.9 million, $1.6 million and $0.3 million respectively, within the Company’s consolidated statements of financial condition. In addition, the Company recognized a deferred tax asset of approximately $0.3 million, resulting from an increased share of Manning & Napier Group's existing deferred tax assets. At September 30, 2021 and December 31, 2020, the Company had recorded a liability of $18.8 million and $19.0 million, respectively, representing the estimated payments due to the selling unit holders under the TRA entered into between Manning & Napier and the other holders of Class A Units of Manning & Napier Group. Of these amounts, approximately $3.2 million and $5.2 million were included in accrued expenses and other liabilities at September 30, 2021 and December 31, 2020, respectively. The Company made payments of approximately $2.1 million during the nine months ended September 30, 2021 and made no payments pursuant to the TRA during the nine months ended September 30, 2020. Obligations pursuant to the TRA are obligations of Manning & Napier. They do not impact the noncontrolling interests. These obligations are not income tax obligations. Furthermore, the TRA has no impact on the allocation of the provision for income taxes to the Company’s net income.

Fair value is determined based on quoted market prices in active markets for identical or similar instruments. Investment securities classified as equity investments, at fair value consist of equity securities and investments in mutual funds for which the Company provides advisory services. At September 30, 2021 and December 31, 2020, equity investments, at fair value consist of investments held by the Company to provide initial cash seeding for product development purposes and investments in mutual funds to hedge economic exposure to market movements on its deferred compensation plan. The Company recognized approximately $0.1 million of net unrealized gains and $0.1 million of net unrealized losses related to investments classified as equity investments, at fair value during the nine months ended September 30, 2021 and 2020, respectively. Investment securities classified as available-for-sale consist of U.S. Treasury notes and corporate bonds to optimize cash management opportunities and for compliance with certain regulatory requirements. As of September 30, 2021 and December 31, 2020, approximately $0.6 million of these securities was considered restricted. The Company periodically reviews each individual security position that has an unrealized loss, or impairment, to determine if that impairment is other-than-temporary. No other-than-temporary impairment charges have been recognized by the Company during the nine months ended September 30, 2021 and 2020.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value MeasurementsFair value is defined as the price that the Company would receive upon selling an investment in an orderly transaction to an independent buyer in the principal or most advantageous market of the investment. A fair value hierarchy is applied that gives the highest priority to unadjusted quoted prices in active markets for identical assets and liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The following three-tier fair value hierarchy prioritizes the inputs used in measuring fair value: • Level 1—observable inputs such as quoted prices in active markets for identical securities; • Level 2—other significant observable inputs (including but not limited to quoted prices for similar securities, interest rates, prepayment rates, credit risk, etc.); and • Level 3—significant unobservable inputs (including the Company’s own assumptions in determining the fair value of investments). The following table summarizes the hierarchy of inputs used to derive the fair value of the Company’s assets as of September 30, 2021 and December 31, 2020: September 30, 2021 Level 1 Level 2 Level 3 Totals (in thousands) Equity securities $ 5,831 $ — $ — $ 5,831 Fixed income securities — 7,299 — 7,299 Mutual funds 2,020 — — 2,020 U.S. Treasury notes — 9,941 — 9,941 Total assets at fair value $ 7,851 $ 17,240 $ — $ 25,091 December 31, 2020 Level 1 Level 2 Level 3 Totals (in thousands) Equity securities $ 5,592 $ — $ — $ 5,592 Fixed income securities — 6,403 — 6,403 Mutual funds 1,004 — — 1,004 U.S. Treasury notes — 10,498 — 10,498 Total assets at fair value $ 6,596 $ 16,901 $ — $ 23,497 Valuations of investments in fixed income securities and U.S. Treasury notes can generally be obtained through independent pricing services. For most bond types, the pricing service utilizes matrix pricing, which considers one or more of the following factors: yield or price of bonds of comparable quality, coupon, maturity, current cash flows, type and current day trade information, as well as dealer supplied prices. These valuations are categorized as Level 2 in the hierarchy. The Company’s policy is to recognize transfers in and transfers out of the valuation levels as of the beginning of the reporting period. There were no transfers between valuation levels during the nine months ended September 30, 2021.

For these leases, the office space or equipment is an explicitly identified asset within the contract. The Company has determined that it has obtained substantially all of the economic benefits from the use of the underlying asset and directs how and for what purpose the asset is used during the term of the contract. Certain of the Company's operating leases have been subleased for which the Company will receive cash totaling approximately $3.7 million over the remaining term of su ch leases. The lease terms for the four subleased operating leases end ranging from 2025 to 2028.

Commitments and Contingencies	Commitments and ContingenciesThe Company may from time to time enter into agreements that contain certain representations and warranties and which provide general indemnifications. The Company may also serve as a guarantor of such obligations. The Company’s maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Company that have not yet occurred. The Company expects any risk of liability associated with such guarantees to be remote. Regulation As an investment adviser to a variety of investment products, the Company and its affiliated broker-dealer are subject to routine reviews and inspections by the SEC and the Financial Industry Regulatory Authority, Inc. From time to time the Company may also be subject to claims, or be involved in various legal proceedings, arising in the ordinary course of its business and other contingencies. The Company does not believe that the outcome of any of these reviews, inspections or other legal proceedings will have a material impact on its consolidated financial statements; however, litigation is subject to many uncertainties, and the outcome of individual litigated matters is difficult to predict. The Company will establish accruals for matters that are probable, can be reasonably estimated, and may take into account any related insurance recoveries to the extent of such recoveries. As of September 30, 2021 and December 31, 2020, the Company has not accrued for any such claims, legal proceedings, or other contingencies.

Earnings per Common Share

Earnings per Common Share	9 Months Ended

Earnings Per Share [Abstract]
Earnings per Common Share	Earnings per Common Share Basic earnings per share (“basic EPS”) is computed using the two-class method to determine net income available to Class A common stock. The two-class method includes an earnings allocation formula that determines earnings per share for each participating security according to dividends declared and undistributed earnings for the period. The Company's restricted Class A common shares granted under the Equity Plan have non-forfeitable dividend rights during their vesting period and are therefore considered participating securities under the two-class method. Under the two-class method, the Company's net income available to Class A common stock is reduced by the amount allocated to the unvested restricted Class A common stock. Basic EPS is calculated by dividing net income available to Class A common stock by the weighted average number of common shares outstanding during the period. Diluted earnings per share (“diluted EPS”) is computed under the more dilutive of either the treasury method or the two-class method. For the diluted calculation, the weighted average number of common shares outstanding during the period is increased by the assumed conversion into Class A common stock of unvested restricted stock units, unvested restricted stock awards, and outstanding stock options (collectively, "outstanding equity awards"), as well as the exchangeable Class A units of Manning & Napier Group, to the extent that such conversion would dilute earnings per share. Net income attributable to noncontrolling interests on the statements of operations represents the portion of earnings attributable to the economic interest of Manning & Napier Group held by the noncontrolling interests (Note 4). For periods in which the outstanding Class A Units of Manning & Napier Group are dilutive to the Company's earnings per share, the calculation of diluted earnings per share also takes into account the incremental net income that would be available to Class A common stock upon the conversion of Class A Units into Class A common stock. The following is a reconciliation of the income and share data used in the basic and diluted EPS computations for the three and nine months ended September 30, 2021 and 2020 under the two-class method: Three months ended September 30, Nine months ended September 30, 2021 2020 2021 2020 (in thousands, except share data) Numerator: Net income attributable to controlling and noncontrolling interests $ 6,710 $ 3,067 $ 19,415 $ 8,185 Less: net income attributable to noncontrolling interests 207 560 1,747 3,274 Net income attributable to Manning & Napier, Inc. $ 6,503 $ 2,507 $ 17,668 $ 4,911 Less: allocation to participating securities — 20 45 52 Net income available to Class A common stock for basic EPS $ 6,503 $ 2,487 $ 17,623 $ 4,859 Plus: reallocation of net income attributable to participating securities — 3 8 4 Plus: incremental net income as a result of conversion of Class A Units of Manning & Napier Group to Class A common stock (60) — — 2,279 Net income available to Class A common stock for diluted EPS $ 6,443 $ 2,490 $ 17,631 $ 7,142 Denominator: Weighted average shares of Class A common stock outstanding - basic 18,481,147 16,176,280 17,493,299 16,041,128 Dilutive effect of outstanding equity awards 3,316,496 2,752,674 3,349,871 1,584,781 Dilutive effect of exchangeable Class A Units 428,812 — — 30,713,850 Weighted average shares of Class A common stock outstanding - diluted 22,226,455 18,928,954 20,843,170 48,339,759 Net income available to Class A common stock per share - basic $ 0.35 $ 0.15 $ 1.01 $ 0.30 Net income available to Class A common stock per share - diluted $ 0.29 $ 0.13 $ 0.85 $ 0.15 Performance-based stock options are excluded from the calculation of diluted EPS for periods in which the associated market condition has not yet been achieved. As such, for the three and nine months ended September 30, 2021, no unvested performance-based stock options were excluded, and for the three and nine months ended September 30, 2020, 2,022,000 unvested performance-based stock options were excluded from the calculation of diluted EPS. For each of the three and nine months ended September 30, 2021, no unvested equity awards were excluded from the calculation of diluted EPS. For the three and nine months ended September 30, 2020, 64,530 and 164,696, respectively, unvested equity awards were excluded from the calculation of diluted EPS because the effect would have been anti-dilutive.

Share-based Payment Arrangement, Noncash Expense [Abstract]
Equity Based Compensation	Equity-Based Compensation The Equity Plan was adopted by the Company's board of directors and approved by shareholders prior to the consummation of the Company's 2011 initial public offering. Under the Equity Plan, a total of 13,142,813 equity interests are authorized for issuance, and may be issued in the form of Class A common stock, restricted stock units, stock options, units of Manning & Napier Group, or certain classes of membership interests in the Company which may convert into units of Manning & Napier Group. At September 30, 2021, a total of 2,154,456 equity interests were available for issuance pursuant to the Equity Plan. The following table summarizes activity related to awards of restricted stock and restricted stock units (collectively, "stock awards") under the Equity Plan for the nine months ended September 30, 2021: Stock Awards Weighted Average Grant Date Fair Value Outstanding at January 1, 2021 3,044,981 $ 2.03 Granted 1,152,369 $ 6.04 Vested (201,778) $ 9.70 Forfeited (182,405) $ 2.16 Outstanding at September 30, 2021 3,813,167 $ 2.83 The weighted average fair value of stock awards granted during the nine months ended September 30, 2021 was $6.04, based on the closing sale price of the Company's Class A common stock as reported on the New York Stock Exchange on the date of grant, and, if not entitled to dividends or dividend equivalents during the vesting period, reduced by the present value of such amounts expected to be paid on the underlying shares during the requisite service period. For the three and nine months ended September 30, 2021, the Company recorded approximately $0.6 million and $2.6 million, respectively, of compensation expense related to stock awards under the Equity Plan. For the three and nine months ended September 30, 2020, the Company recorded approximately $0.7 million and $2.5 million, respectively, of compensation expense related to stock awards under the Equity Plan. The aggregate intrinsic value of stock awards that vested during each of the nine months ended September 30, 2021 and 2020 was approximately $1.5 million and $0.9 million, respectively. As of September 30, 2021, there was unrecognized compensation expense of approximately $8.2 million related to stock awards, which the Company expects to recognize over a weighted average period of approximately 3.9 years. A summary of activity under the Equity Plan related to stock option awards during the nine months ended September 30, 2021 is presented below: Stock Option Awards Weighted Average Exercise Price Weighted Average Contractual Term Aggregate Outstanding at January 1, 2021 2,250,000 $ 2.01 Granted — $ — Exercised (1,750,000) $ 2.01 Forfeited — $ — Outstanding at September 30, 2021 500,000 $ 2.01 3.8 $ 3,560 Exercisable at September 30, 2021 333,332 $ 2.01 3.6 $ 2,373 For the three and nine months ended September 30, 2021, the Company recorded approximately less than $0.1 million and $0.2 million, respectively, of compensation expense related to stock options under the Equity Plan. For the three and nine months ended September 30, 2020, the Company recorded approximately $0.1 million and $0.4 million, respectively, of compensation expense related to stock options under the Equity Plan. As of September 30, 2021, there was unrecognized compensation expense of less than $0.1 million related to stock options, which the Company expects to recognize over a weighted average period of approximately 0.4 years. In connection with the vesting of restricted stock units and exercise of stock options during the nine months ended September 30, 2021, the Company withheld a total of 710,019 shares of Class A common stock to satisfy approximately $5.2 million of employee income tax withholding requirements. These net share settlements had the effect of shares repurchased and retired by the Company, as they reduced the total number of Class A common shares outstanding.

Income Taxes

Income Taxes	9 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	Income TaxesThe Company is comprised of entities that have elected to be treated as either a limited liability company ("LLC") or a “C-Corporation". As such, the entities functioning as LLCs are not liable for or able to benefit from U.S. federal and most state income taxes on their earnings, and earnings (losses) will be included in the personal income tax returns of each entity’s unit holders. The entities functioning as C-Corporations are liable for or able to benefit from U.S. federal and state and local income taxes on their earnings and losses, respectively. In calculating the provision for income taxes, the Company uses an estimate of the annual effective tax rate based upon the facts and circumstances at each interim period. On a quarterly basis, the estimated annual effective tax rate is adjusted, as appropriate, based upon changes in facts and circumstances, if any, as compared to those forecasted at the beginning of the fiscal year and at each interim period thereafter. The Company’s income tax provision (benefit) and effective tax rate were as follows: Three months ended September 30, Nine months ended September 30, 2021 2020 2021 2020 (in thousands) Income before provision for (benefit from) income taxes $ 9,233 $ 4,805 $ 23,926 $ 8,157 Effective tax rate 27.3 % 36.2 % 18.9 % (0.3) % Provision for (benefit from) income taxes 2,523 1,738 4,511 (28) Provision for (benefit from) income taxes at statutory rate 1,939 1,009 5,024 1,713 Difference between tax at effective vs. statutory rate $ 584 $ 729 $ (513) $ (1,741) The provision for (benefit from) income taxes includes a benefit attributable to the fact that the Company’s operations include a series of flow-through entities which are generally not subject to federal and most state income taxes. Accordingly, a portion of the Company’s earnings are not subject to corporate level taxes. The Company recognized a reduced benefit from flow-through entities during the nine months ended September 30, 2021 compared to September 30, 2020 due to a higher portion of Manning & Napier Group's earnings subject to taxation at the C-Corporation level attributed to Manning & Napier Inc.'s increased ownership of Manning & Napier Group as of September 30, 2021 compared to September 30, 2020. In addition, the effective rate during the nine months ended September 30, 2021 is lower than the statutory rate of 21% due to the incremental tax benefits realized from the exercise of stock option awards during the first and second quarters of 2021, partially offset by the impacts from permanent differences between book and tax income, including but not limited to Section 162(m) of the IRC which limits the annual amount of deductible compensation. During the three months ended September 30, 2021, the Company reached a settlement with a certain state related to the Company's 2016, 2017 and 2018 corporate income tax returns. As a result, the Company recognized approximately $0.3 million within its provision for income taxes during the three months ended September 30, 2021.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	9 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and related rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) for interim financial reporting and include all adjustments, consisting only of normal recurring adjustments which are, in the opinion of management, necessary for a fair statement of the results for the interim period. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates or assumptions that affect the reported amounts and disclosures in the consolidated financial statements. Actual results could differ from these estimates or assumptions.
Principles of Consolidation	Principles of Consolidation The Company consolidates all majority-owned subsidiaries. As of September 30, 2021, Manning & Napier holds an economic interest of approximately 97.7% in Manning & Napier Group and, as managing member, controls all of the business and affairs of Manning & Napier Group. As a result, the Company consolidates the financial results of Manning & Napier Group and records a noncontrolling interest on its consolidated statements of financial condition with respect to the remaining economic interest in Manning & Napier Group held by M&N Group Holdings. All material intercompany transactions have been eliminated in consolidation. In accordance with Accounting Standards Update ("ASU") 2015-02, Consolidation (Topic 810) – Amendments to the Consolidation Analysis , the determination of whether a company is required to consolidate an entity is based on, among other things, an entity’s purpose and design, a company’s ability to direct the activities of the entity that most significantly impact the entity’s economic performance, and whether a company is obligated to absorb losses or receive benefits that could potentially be significant to the entity. The standard also requires ongoing assessments of whether a company is the primary beneficiary of a variable interest entity (“VIE”). When utilizing the voting interest entity ("VOE") model, controlling financial interest is generally defined as majority ownership of voting interests. The Company provides seed capital to its investment teams to develop new strategies and services for its clients. The original seed investment may be held in a separately managed account, comprised solely of the Company's investments or within a mutual fund, where the Company's investments may represent all or only a portion of the total equity investment in the mutual fund. Pursuant to U.S. GAAP, the Company evaluates its investments in mutual funds on a regular basis and consolidates such mutual funds for which it holds a controlling financial interest. When no longer deemed to hold a controlling financial interest, the Company would deconsolidate the fund and classify the remaining investment as either an equity method investment, equity investments, at fair value, or as trading securities, as applicable. As of September 30, 2021 and December 31, 2020, the Company did not have investments classified as an equity method investment. The Company serves as the investment adviser for Manning & Napier Fund, Inc. series of mutual funds (the “Fund”), Exeter Trust Company Collective Investment Trusts (“CIT”) and Rainier Multiple Investment Trust. The Fund, CIT and Rainier Multiple Investment Trust are legal entities, the business and affairs of which are managed by their respective boards of directors. As a result, each of these entities is a VOE. The Company holds, in limited cases, direct investments in a mutual fund (which are made on the same terms as are available to other investors) and consolidates each of these entities where it has a controlling financial interest or a majority voting interest. The Company's investments in the Fund amounted to approximately $2.0 million as of September 30, 2021 and $1.0 million as of December 31, 2020. As of September 30, 2021 and December 31, 2020, the Company did not have a controlling financial interest in any mutual fund.
Revenue	Revenue Investment Management: Investment management fees are computed as a percentage of assets under management ("AUM"). The Company's performance obligation is a series of services that form part of a single performance obligation satisfied over time. Separately managed accounts are paid in advance, typically for a semi-annual or quarterly period, or in arrears, typically for a monthly or quarterly period. When investment management fees are paid in advance, the Company defers the revenue as a contract liability and recognizes it over the applicable period. When investment management fees are paid in arrears, the Company estimates revenue and records a contract asset (accrued accounts receivable) based on AUM as of the most recent month end date. Mutual funds and collective investment trust investment management revenue is calculated and earned daily based on AUM. Revenue is presented net of cash rebates and fees waived pursuant to contractual expense limitations of the funds. The Company also has agreements with third parties who provide recordkeeping and administrative services for employee benefit plans participating in the collective investment trusts. The Company is acting as an agent on behalf of the employee benefit plan sponsors, therefore, investment management revenue is recorded net of fees paid to third party service providers. Distribution and shareholder servicing: The Company receives distribution and servicing fees for providing services to its affiliated mutual funds. Revenue is computed and earned daily based on a percentage of AUM. The performance obligation is a series of services that form part of a single performance obligation satisfied over time. The Company has agreements with third parties who provide distribution and administrative services for its mutual funds. The agreements are evaluated to determine whether revenue should be reported gross or net of payments to third-party service providers. The Company controls the services provided and acts as a principal in the relationship. Therefore, distribution and shareholder servicing revenue is recorded gross of fees paid to third parties. Custodial services: Custodial service fees are calculated as a percentage of the client’s market value with additional fees charged for certain transactions. For the safeguarding and administrative services that are subject to a percentage of market
Cash and Cash Equivalents	Cash and Cash Equivalents The Company generally considers all highly liquid investments with original maturities of three months or less to be cash equivalents. Cash and cash equivalents are primarily held in operating accounts at major financial institutions and also in money market securities. Cash equivalents are stated at cost, which approximates market value due to the short-term maturity of these investments. The fair value of cash equivalents has been classified as Level 1 in accordance with the fair value hierarchy.
Investment Securities	Investment Securities Investment securities are classified as either equity investments, trading, equity method investments or available-for-sale and are carried at fair value. Fair value is determined based on quoted market prices in active markets for identical or similar instruments. Investment securities classified as equity investments, at fair value consist of equity securities and investments in mutual funds for which the Company provides advisory services. Realized and unrealized gains and losses on equity investments, at fair value or trading securities, as applicable, are recorded in net gains (losses) on investments in the consolidated statements of operations.
Property and Equipment	Property, Equipment, Software and Depreciation Property and equipment is presented net of accumulated depreciation of approximately $12.0 million and $12.6 million as of September 30, 2021 and December 31, 2020, respectively. Capitalized implementation costs for hosting arrangements are included within prepaid expenses and other assets on the Company's statements of financial condition and totaled approximately $6.7 million and $5.3 million, net of accumulated amortization, as of September 30, 2021 and December 31, 2020, respectively.
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill represents the excess cost over the fair value of the identifiable net assets of acquired companies. Identifiable intangible assets generally represent the cost of client relationships and investment management agreements acquired as well as trademarks. Goodwill and indefinite-lived assets are tested for impairment annually or more frequently if events or circumstances indicate that the carrying value may not be recoverable. Intangible assets subject to amortization are tested for impairment whenever events or circumstances indicate that the carrying value may not be recoverable. Goodwill and intangible assets require significant management estimate and judgment, including the valuation and expected life determination in connection with the initial purchase price allocation and the ongoing evaluation for impairment.
Leases	Leases The Company determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use ("ROU") assets, accrued expenses and other liabilities and operating lease liabilities, non-current on its consolidated statements of financial condition. Finance leases are included in other long-term assets, accrued expenses and other liabilities, and other long-term liabilities on its consolidated statements of financial condition. ROU assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. Operating lease ROU assets and lease liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the Company's leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The incremental borrowing rate, for each identified lease, is the rate of interest that the Company would have to pay to borrow on a collateralized basis over a similar term. The operating lease ROU asset is reduced for any lease incentives. The Company's lease terms may include options to extend or terminate the lease when it is reasonably certain that it will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which are combined for all classes of underlying assets.
Treasury Stock	Treasury Stock On February 3, 2021, the Board of Directors approved a share repurchase program authorizing the Company to purchase up to $10.0 million of Manning & Napier Inc. Class A common shares through December 31, 2021. As of September 30, 2021, the Company had purchased 749,005 shares of Class A common stock for an aggregate price of approximately $5.7 million.
Operating Segments	Operating SegmentsThe Company operates in one segment, the investment management industry.
Recently Adopted Accounting Pronouncements	Recent Accounting Pronouncements In December 2019, the Financial Accounting Standards Board ("FASB") issued ASU 2019-12, Simplifying the Accounting for Income Taxes , which is intended to simplify various aspects of the income tax accounting guidance, including interim-period accounting for enacted changes in the tax law. ASU 2019-12 is effective for public business entities for fiscal years beginning after December 15, 2020, including interim periods within those fiscal years, and early adoption is permitted. The adoption of this ASU as of January 1, 2021 did not have a material impact on the Company's consolidated financial statements.
