Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Critical Accounting Policies There have been no significant changes in our critical accounting policies and estimates from those that were disclosed in our Annual Report on Form 10-K for the year ended December 31, 2016 . 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 our Annual Report on Form 10-K for the year ended December 31, 2016 . 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. Revision of Previously Reported Consolidated Statements of Operations In the quarter ended September 30, 2016, the Company revised its treatment of payments made to certain advisory clients, in accordance with Accounting Standard Codification ("ASC") 605-50, Revenue Recognition - Customer Payments and Incentives to properly present these payments as a reduction to revenue. The Company assessed the materiality of this item on its fiscal year ended December 31, 2015, and all prior and subsequent periods, and concluded that the reclassification was not material to any such periods. The statements of operations for the three and six months ended June 30, 2016 included herein have been revised to reflect the proper presentation of investment management services revenue and distribution, servicing and custody expenses. The reclassification has no impact on operating income or net income. The impact is illustrated below: Three months ended June 30, 2016 Six months ended June 30, 2016 (in thousands) Investment management services revenue, as previously reported $ 67,541 $ 132,079 Revision (3,036 ) (5,532 ) Investment management services revenue, as revised $ 64,505 $ 126,547 Distribution, servicing and custody expenses, as previously reported $ 11,986 $ 23,324 Revision (3,036 ) (5,532 ) Distribution, servicing and custody expenses, as revised $ 8,950 $ 17,792 Principles of Consolidation The Company consolidates all majority-owned subsidiaries. In addition, as of June 30, 2017 , Manning & Napier holds an economic interest of approximately 17.8% in Manning & Napier Group but, 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 Manning & Napier Group Holdings, LLC (“M&N Group Holdings”) and Manning & Napier Capital Company, LLC (“MNCC”). 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 products 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 or as trading securities, as applicable. 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”), Rainier Investment Management Mutual Funds and Rainier Multiple Investment Trust. The Fund, CIT, Rainier Investment Management Mutual Funds 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 $1.4 million as of June 30, 2017 and $1.3 million as of December 31, 2016 . As of December 31, 2016 , the Company maintained a controlling financial interest in one mutual fund, Manning & Napier Fund, Inc. Quality Equity Series, and consolidated the mutual fund. As of June 30, 2017, the Company no longer maintained a controlling financial interest, but did retain significant influence in the mutual fund, which was accounted for as an equity method investment. 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 have been classified as Level 1 in accordance with the fair value hierarchy. Investment Securities Investment securities are classified as either 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 trading consist of equity securities, fixed income securities, and investments in mutual funds for which the Company provides advisory services. Realized and unrealized gains and losses on trading securities are recorded in net gains (losses) on investments in the consolidated statements of operations. At June 30, 2017 , trading securities consist solely of investments held by the Company to provide initial cash seeding for product development purposes. Investments classified as equity method investments represent seed investments in which the Company owns between 20-50% of the outstanding voting interests in the affiliated fund or when it is determined that the Company is able to exercise significant influence but not control over the investments. If the seed investment results in significant influence, but not control, the investment will be accounted for as an equity method investment. When using the equity method, the Company recognizes its share of the investee's net income or loss for the period which is 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 other short-term investments. 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 stockholders’ 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 and Equipment Property and equipment is presented net of accumulated depreciation of approximately $11.9 million and $11.6 million as of June 30, 2017 and December 31, 2016 , 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. On May 10, 2017, the Company entered into an agreement to sell certain U.S. mutual funds to a third party. The transaction is expected to close during the third quarter of 2017, with the selling price based on the total assets under management on the transaction closing date. As of June 30, 2017, the assets under management for these products was approximately $0.5 billion . The carrying value of the intangible assets for client relationships associated with these products was $0 as of June 30, 2017. Operating Segments The Company operates in one segment, the investment management industry. Revenue The majority of the Company’s revenues are based on fees charged to manage customers’ portfolios. Investment management fees are generally computed as a percentage of assets under management ("AUM") and recognized as earned. Fees for providing investment advisory services are computed and billed in accordance with the provisions of the applicable investment management agreements. For the Company’s separately managed accounts, clients either pay investment management fees 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 and recognizes it over the applicable period. When investment management fees are paid in arrears, the Company estimates revenues based on AUM market values as of the most recent month end date, and adjusts to actual when billed. For mutual funds and collective investment trust vehicles, the Company’s fees are calculated and earned daily based on AUM. Investment management fees are presented net of cash rebates and fees waived pursuant to contractual expense limitations of the funds. The Company is contractually obligated to make payments to certain advisory clients with the intent of providing those clients a discounted fee. In accordance with ASC 605-50 , Revenue Recognition - Customer Payments and Incentives , these payments are presented as a reduction to revenue. Incentives reported as a reduction to revenue for the three and six months ended June 30, 2017 were less than $0.1 million and $3.4 million , respectively, and $3.0 million and $5.5 million for the three and six months ended June 30, 2016 , respectively. The Company has agreements with third parties who provide distribution and administrative services for its mutual funds, collective investment trusts and certain separately managed accounts. Third party agreements are evaluated against ASC 605-45 Revenue Recognition - Principal Agent Considerations to determine whether revenue should be reported gross or net of payments to third-party service providers. In management's judgment there are various indicators that support gross revenue reporting, the most notable being the Company acts as primary obligor and therefore principal service provider. Based on this evaluation, investment management service revenue is recorded gross of distribution and administrative fees paid to third parties. Advisory Agreements The Company derives significant revenue from its role as advisor to affiliated mutual funds and collective investment trusts. Fees earned for advisory related services were approximately $21.1 million and $45.2 million for the three and six months ended June 30, 2017 , respectively, and $29.9 million and $57.8 million for the three and six months ended June 30, 2016 , respectively, which represents greater than 10% of the Company's revenue in each period. Recent Accounting Pronouncements In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) , which supersedes existing accounting standards for revenue recognition and creates a single framework. The revenue standard contains principals that will be applied to determine the measurement of revenue and timing of recognition. We will adopt the new standard on its effective date of January 1, 2018. We have not yet selected whether we will adopt the standard using the retrospective approach with adjustment to each prior period or modified retrospective approach with the cumulative effect of initial application recognized at the date of initial application. We are continuing to assess the impact of adoption though early conclusions indicate the standard will not have a material impact on our financial condition and results of operations. While we have not identified material changes in the timing of revenue recognition, we continue to evaluate the presentation of certain revenue related costs on a gross versus net basis as well as the additional disclosures required by the standard. In January 2016, the FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities, which requires all equity investments to be measured at fair value with changes in the fair value recognized through net income. ASU 2016-01 will be effective on January 1, 2018 and will result in a cumulative-effect adjustment to the balance sheet upon adoption. The Company is currently evaluating the impact that ASU 2016-01 will have on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which is intended to increase transparency and comparability among organizations by recognizing all lease transactions (with terms in excess of 12 months) on the balance sheet as a lease liability and a right-of-use asset (as defined). The new guidance will be effective for fiscal years beginning after December 15, 2018, with earlier application permitted. Upon adoption, the lessee will apply the new standard retrospectively to all periods presented or retrospectively using a cumulative effect adjustment in the year of adoption. The Company is currently evaluating the impact that ASU 2016-02 will have on its consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, Stock Compensation - Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting , which is intended to simplify several aspects of the accounting for share-based payment award transactions. The guidance is effective for fiscal years beginning after December 15, 2016. The Company's adoption of these amendments on January 1, 2017 did not have a material impact on its consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments , to clarify guidance on the classification of certain cash receipts and cash payments in the statement of cash flows. The FASB issued the ASU with the intent of reducing diversity in practice regarding eight types of cash flows. The ASU is effective for annual reporting periods beginning after December 15, 2017, including interim periods within those annual reporting periods. The Company is evaluating the effect of adopting this new accounting standard. In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment , which simplifies the accounting for goodwill impairments by eliminating step two from the goodwill impairment test. The ASU requires goodwill impairments to be measured on the basis of the fair value of the reporting unit relative to the reporting unit's carrying amount rather than on the basis of the implied amount of goodwill relative to the goodwill balance of the reporting unit. The ASU is effective for annual and interim impairment tests for periods beginning after December 15, 2019. Early adoption is allowed for annual and interim impairment tests occurring after January 1, 2017. The Company is evaluating the effect of adopting this new accounting standard.

Business Combinations [Abstract]
Acquisitions	Acquisitions On April 30, 2016 , the Company acquired a majority ownership interest in Rainier Investment Management, LLC ("Rainier”), an active investment management firm.

As of June 30, 2017 , the Company's ownership interest in Rainier increased to 86% , due to the forfeiture of unvested ownership interests by certain individuals retiring from Rainier subsequent to the acquisition. Consideration transferred included an upfront cash payment on the transaction closing date of $13.0 million , a portion of which was held in escrow. During the second quarter of 2017, the Company received approximately $0.3 million from amounts held in escrow for post closing adjustments. Additional cash payments of up to $32.5 million over a four year period are contingent upon Rainier’s achievement of certain annual financial targets. The fair value of the liability for this contingent consideration recognized on the acquisition date was $3.5 million . As of June 30, 2017 and December 31, 2016, the fair value of this contingent liability was $0 .

Noncontrolling Interest [Abstract]
Noncontrolling Interests	Noncontrolling Interests Manning & Napier holds an economic interest of approximately 17.8% in Manning & Napier Group, but 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 statement of financial condition with respect to the remaining approximately 82.2% aggregate economic interest in Manning & Napier Group held by M&N Group Holdings and MNCC. 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 provides a reconciliation from “Income before provision for income taxes” to “Net income attributable to Manning & Napier, Inc.”: Three months ended June 30, Six months ended June 30, 2017 2016 2017 2016 (in thousands) Income before provision for income taxes $ 15,831 $ 23,243 $ 33,688 $ 47,101 Less: gain (loss) before provision for income taxes of Manning & Napier, Inc.

(2) Income before provision for 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 for the respective periods. (3) The consolidated provision for income taxes is equal to the sum of (i) the provision for income taxes for entities other than Manning & Napier, Inc. and (ii) the provision for income taxes of Manning & Napier, Inc. which includes all U.S. federal and state income taxes. The consolidated provision for income taxes was $1.2 million and $2.6 million for the three and six months ended June 30, 2017 , respectively, and $1.5 million and $3.2 million for the three and six months ended June 30, 2016 , respectively. As of June 30, 2017 , a total of 63,941,860 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, such units may be exchangeable for shares of the Company's Class A common stock. For any units exchanged, the Company will (i) pay an amount of cash equal to the number of units exchanged 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 31, 2017, M&N Group Holdings and MNCC exchanged a total of 1,842,711 Class A units of Manning & Napier Group for approximately $9.8 million in cash. Subsequent to the exchange the Class A units were retired, resulting in an increase in Manning & Napier's ownership in Manning & Napier Group. In addition, during the six months ended June 30, 2017 , 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, net of forfeitures of unvested restricted stock awards. The following is the impact to the Company's equity ownership interest in Manning & Napier Group for the six months ended June 30, 2017 : Manning & Napier Group Class A Units Held Manning & Napier Total Manning & Napier Ownership % As of December 31, 2016 13,826,575 65,784,571 79,611,146 17.4% Class A Units issued (1) 46,467 — 46,467 —% Class A Units exchanged — (1,842,711 ) (1,842,711 ) 0.4% As of June 30, 2017 13,873,042 63,941,860 77,814,902 17.8% ______________________ (1) The impact of the transaction of Manning & Napier's ownership was less than 0.1% . 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 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. At June 30, 2017 and December 31, 2016 , the Company had recorded a liability of $37.1 million representing the estimated payments due to the selling unit holders under the tax receivable agreement ("TRA") entered into between Manning & Napier and the other holders of Class A Units of Manning & Napier Group. Of these amounts, $2.4 million were included in accrued expenses and other liabilities at June 30, 2017 and December 31, 2016 . The Company made no payments pursuant to the TRA during the six months ended June 30, 2017 and 2016 . 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 Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair 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 provided 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 provides the hierarchy of inputs used to derive the fair value of the Company’s financial instruments measured at fair value on a recurring basis as of June 30, 2017 and December 31, 2016 : June 30, 2017 Level 1 Level 2 Level 3 Totals (in thousands) Equity securities $ 6,514 $ — $ — $ 6,514 Fixed income securities 1,165 6,858 — 8,023 Mutual funds 1,411 — — 1,411 U.S. Treasury notes — 7,111 — 7,111 Short-term investments 22,192 — — 22,192 Total assets at fair value $ 31,282 $ 13,969 $ — $ 45,251 Contingent consideration liability $ — $ — $ — $ — Total liabilities at fair value $ — $ — $ — $ — December 31, 2016 Level 1 Level 2 Level 3 Totals (in thousands) Equity securities $ 7,176 $ — $ — $ 7,176 Fixed income securities 1,071 6,096 — 7,167 Mutual funds 288 — — 288 Mutual funds - consolidated funds 995 — — 995 U.S. Treasury notes — 7,100 — 7,100 Short-term investments 14,744 — — 14,744 Total assets at fair value $ 24,274 $ 13,196 $ — $ 37,470 Contingent consideration liability $ — $ — $ — $ — Total liabilities at fair value $ — $ — $ — $ — Short-term investments consists of certificate of deposits ("CDs") that are stated at cost, which approximate fair value due to the short maturity of the investments. 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. Contingent consideration was a component of the purchase price of Rainier (Note 3). The contingent consideration is payable over a four year period upon Rainier’s achievement of certain financial targets. The fair value of the contingent consideration is calculated on a quarterly basis by forecasting Rainier’s adjusted earnings before interest, taxes and amortization ("EBITA") as defined by the purchase agreement over the contingency period with changes in the fair value included in other operating costs in the consolidated statements of operations. There were no changes in contingent consideration liability measured at fair value using significant unobservable inputs (Level 3) for the six months ended June 30, 2017 . The fair value was $0 at June 30, 2017 and December 31, 2016 . 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 Levels during the six months ended June 30, 2017 .

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies The 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 of one or more of the Manning & Napier Group entities. 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, Financial Industry Regulatory Authority, Inc., National Futures Association and U.S. Commodity Futures Trading Commission. From time to time, the Company may also be subject to claims, be involved in various legal proceedings arising in the ordinary course of its business and be subject to 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 June 30, 2017 and December 31, 2016 , the Company has not accrued for any such claims, legal proceedings, or other contingencies.

Earnings per Common Share

Earnings per Common Share	6 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 2011 Equity Compensation Plan (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 the unvested equity awards and the exchangeable units of Manning & Napier Group, to the extent that such conversion would dilute earnings per share. The following is a reconciliation of the income and share data used in the basic and diluted earnings per share computations for the three and six months ended June 30, 2017 and 2016 under the two-class method: Three months ended June 30, Six months ended June 30, 2017 2016 2017 2016 (in thousands, except share data) Net income attributable to controlling and noncontrolling interests $ 14,589 $ 21,698 $ 31,103 $ 43,882 Less: net income attributable to noncontrolling interests 12,904 19,093 27,521 38,859 Net income attributable to Manning & Napier, Inc. $ 1,685 $ 2,605 $ 3,582 $ 5,023 Less: allocation to participating securities 102 172 212 334 Net income available to Class A common stock $ 1,583 $ 2,433 $ 3,370 $ 4,689 Weighted average shares of Class A common stock outstanding - basic 14,111,368 13,960,768 14,077,313 13,852,949 Dilutive effect from unvested equity awards 187,466 282,811 179,598 356,862 Weighted average shares of Class A common stock outstanding - diluted 14,298,834 14,243,579 14,256,911 14,209,811 Net income available to Class A common stock per share - basic $ 0.12 $ 0.17 $ 0.25 $ 0.34 Net income available to Class A common stock per share - diluted $ 0.12 $ 0.17 $ 0.25 $ 0.33 The Company’s Class B common stock represent voting interests and do not participate in the earnings of the Company. Accordingly, there is no basic or diluted EPS related to the Company’s Class B common stock. For both the three and six months ended June 30, 2017 , 830,000 unvested equity awards were excluded from the calculation of diluted earnings per common share because the effect would have been anti-dilutive. For the three and six months ended June 30, 2016 , 990,000 and 1,010,000 , respectively, unvested equity awards were excluded from the calculation of diluted earnings per common share because the effect would have been anti-dilutive. At June 30, 2017 and 2016 there were 63,941,860 and 65,784,571 Class A Units of Manning & Napier Group outstanding, respectively, which, subject to certain restrictions, may be exchangeable for up to an equivalent number of the Company's Class A common stock. These units were not included in the calculation of diluted earnings per common share for the three and six months ended June 30, 2017 or for the three and six months ended June 30, 2016 , because the effect would have been anti-dilutive.

During the six months ended June 30, 2017 and 2016 , the Company withheld a total of 69,597 and 111,729 restricted shares, respectively, as a result of net share settlements to satisfy employee tax withholding obligations. The Company paid approximately $0.3 million and $1.0 million in employee tax withholding obligations related to these settlements during the six months ended June 30, 2017 and 2016 , respectively. These net share settlements had the effect of shares repurchased and retired by the Company, as they reduced the number of shares outstanding.

Income Taxes	Income Taxes The 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 LLC’s 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. The Company’s income tax provision and effective tax rate were as follows: Three months ended June 30, Six months ended June 30, 2017 2016 2017 2016 (in thousands) Earnings from continuing operations before income taxes $ 15,831 $ 23,243 $ 33,688 $ 47,101 Effective tax rate 7.8 % 6.6 % 7.7 % 6.8 % Provision for income taxes 1,242 1,545 2,585 3,219 Provision for income taxes statutory rate 5,383 8,135 11,454 16,485 Difference between tax at effective vs. statutory rate $ (4,141 ) $ (6,590 ) $ (8,869 ) $ (13,266 ) For the three and six months ended June 30, 2017 and 2016 , the difference between the Company’s recorded provision and the provision that would result from applying the U.S. statutory rate of 34% and 35% , respectively, is primarily attributable to the benefit resulting from the fact that a significant portion of 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.

Revision of Previously Reported Consolidated Statements of Operations	Revision of Previously Reported Consolidated Statements of Operations In the quarter ended September 30, 2016, the Company revised its treatment of payments made to certain advisory clients, in accordance with Accounting Standard Codification ("ASC") 605-50, Revenue Recognition - Customer Payments and Incentives to properly present these payments as a reduction to revenue. The Company assessed the materiality of this item on its fiscal year ended December 31, 2015, and all prior and subsequent periods, and concluded that the reclassification was not material to any such periods. The statements of operations for the three and six months ended June 30, 2016 included herein have been revised to reflect the proper presentation of investment management services revenue and distribution, servicing and custody expenses. The reclassification has no impact on operating income or net income. The impact is illustrated below: Three months ended June 30, 2016 Six months ended June 30, 2016 (in thousands) Investment management services revenue, as previously reported $ 67,541 $ 132,079 Revision (3,036 ) (5,532 ) Investment management services revenue, as revised $ 64,505 $ 126,547 Distribution, servicing and custody expenses, as previously reported $ 11,986 $ 23,324 Revision (3,036 ) (5,532 ) Distribution, servicing and custody expenses, as revised $ 8,950 $ 17,792
Principles of Consolidation	Principles of Consolidation The Company consolidates all majority-owned subsidiaries. In addition, as of June 30, 2017 , Manning & Napier holds an economic interest of approximately 17.8% in Manning & Napier Group but, 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 Manning & Napier Group Holdings, LLC (“M&N Group Holdings”) and Manning & Napier Capital Company, LLC (“MNCC”). 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 products 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 or as trading securities, as applicable. 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”), Rainier Investment Management Mutual Funds and Rainier Multiple Investment Trust. The Fund, CIT, Rainier Investment Management Mutual Funds 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 $1.4 million as of June 30, 2017 and $1.3 million as of December 31, 2016 . As of December 31, 2016 , the Company maintained a controlling financial interest in one mutual fund, Manning & Napier Fund, Inc. Quality Equity Series, and consolidated the mutual fund. As of June 30, 2017, the Company no longer maintained a controlling financial interest, but did retain significant influence in the mutual fund, which was accounted for as an equity method investment.
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 have been classified as Level 1 in accordance with the fair value hierarchy.
Investment Securities	Investment Securities Investment securities are classified as either 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 trading consist of equity securities, fixed income securities, and investments in mutual funds for which the Company provides advisory services. Realized and unrealized gains and losses on trading securities are recorded in net gains (losses) on investments in the consolidated statements of operations. At June 30, 2017 , trading securities consist solely of investments held by the Company to provide initial cash seeding for product development purposes. Investments classified as equity method investments represent seed investments in which the Company owns between 20-50% of the outstanding voting interests in the affiliated fund or when it is determined that the Company is able to exercise significant influence but not control over the investments. If the seed investment results in significant influence, but not control, the investment will be accounted for as an equity method investment. When using the equity method, the Company recognizes its share of the investee's net income or loss for the period which is 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 other short-term investments. 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 stockholders’ 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.
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. On May 10, 2017, the Company entered into an agreement to sell certain U.S. mutual funds to a third party. The transaction is expected to close during the third quarter of 2017, with the selling price based on the total assets under management on the transaction closing date. As of June 30, 2017, the assets under management for these products was approximately $0.5 billion . The carrying value of the intangible assets for client relationships associated with these products was $0 as of June 30, 2017.
Operating Segments	Operating Segments The Company operates in one segment, the investment management industry.
Revenue	Revenue The majority of the Company’s revenues are based on fees charged to manage customers’ portfolios. Investment management fees are generally computed as a percentage of assets under management ("AUM") and recognized as earned. Fees for providing investment advisory services are computed and billed in accordance with the provisions of the applicable investment management agreements. For the Company’s separately managed accounts, clients either pay investment management fees 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 and recognizes it over the applicable period. When investment management fees are paid in arrears, the Company estimates revenues based on AUM market values as of the most recent month end date, and adjusts to actual when billed. For mutual funds and collective investment trust vehicles, the Company’s fees are calculated and earned daily based on AUM. Investment management fees are presented net of cash rebates and fees waived pursuant to contractual expense limitations of the funds. The Company is contractually obligated to make payments to certain advisory clients with the intent of providing those clients a discounted fee. In accordance with ASC 605-50 , Revenue Recognition - Customer Payments and Incentives , these payments are presented as a reduction to revenue. Incentives reported as a reduction to revenue for the three and six months ended June 30, 2017 were less than $0.1 million and $3.4 million , respectively, and $3.0 million and $5.5 million for the three and six months ended June 30, 2016 , respectively. The Company has agreements with third parties who provide distribution and administrative services for its mutual funds, collective investment trusts and certain separately managed accounts. Third party agreements are evaluated against ASC 605-45 Revenue Recognition - Principal Agent Considerations to determine whether revenue should be reported gross or net of payments to third-party service providers. In management's judgment there are various indicators that support gross revenue reporting, the most notable being the Company acts as primary obligor and therefore principal service provider. Based on this evaluation, investment management service revenue is recorded gross of distribution and administrative fees paid to third parties.
Advisory Agreements	Advisory Agreements The Company derives significant revenue from its role as advisor to affiliated mutual funds and collective investment trusts. Fees earned for advisory related services were approximately $21.1 million and $45.2 million for the three and six months ended June 30, 2017 , respectively, and $29.9 million and $57.8 million for the three and six months ended June 30, 2016 , respectively, which represents greater than 10% of the Company's revenue in each period.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) , which supersedes existing accounting standards for revenue recognition and creates a single framework. The revenue standard contains principals that will be applied to determine the measurement of revenue and timing of recognition. We will adopt the new standard on its effective date of January 1, 2018. We have not yet selected whether we will adopt the standard using the retrospective approach with adjustment to each prior period or modified retrospective approach with the cumulative effect of initial application recognized at the date of initial application. We are continuing to assess the impact of adoption though early conclusions indicate the standard will not have a material impact on our financial condition and results of operations. While we have not identified material changes in the timing of revenue recognition, we continue to evaluate the presentation of certain revenue related costs on a gross versus net basis as well as the additional disclosures required by the standard. In January 2016, the FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities, which requires all equity investments to be measured at fair value with changes in the fair value recognized through net income. ASU 2016-01 will be effective on January 1, 2018 and will result in a cumulative-effect adjustment to the balance sheet upon adoption. The Company is currently evaluating the impact that ASU 2016-01 will have on its consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which is intended to increase transparency and comparability among organizations by recognizing all lease transactions (with terms in excess of 12 months) on the balance sheet as a lease liability and a right-of-use asset (as defined). The new guidance will be effective for fiscal years beginning after December 15, 2018, with earlier application permitted. Upon adoption, the lessee will apply the new standard retrospectively to all periods presented or retrospectively using a cumulative effect adjustment in the year of adoption. The Company is currently evaluating the impact that ASU 2016-02 will have on its consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, Stock Compensation - Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting , which is intended to simplify several aspects of the accounting for share-based payment award transactions. The guidance is effective for fiscal years beginning after December 15, 2016. The Company's adoption of these amendments on January 1, 2017 did not have a material impact on its consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230), Classification of Certain Cash Receipts and Cash Payments , to clarify guidance on the classification of certain cash receipts and cash payments in the statement of cash flows. The FASB issued the ASU with the intent of reducing diversity in practice regarding eight types of cash flows. The ASU is effective for annual reporting periods beginning after December 15, 2017, including interim periods within those annual reporting periods. The Company is evaluating the effect of adopting this new accounting standard. In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment , which simplifies the accounting for goodwill impairments by eliminating step two from the goodwill impairment test. The ASU requires goodwill impairments to be measured on the basis of the fair value of the reporting unit relative to the reporting unit's carrying amount rather than on the basis of the implied amount of goodwill relative to the goodwill balance of the reporting unit. The ASU is effective for annual and interim impairment tests for periods beginning after December 15, 2019. Early adoption is allowed for annual and interim impairment tests occurring after January 1, 2017. The Company is evaluating the effect of adopting this new accounting standard.
Property, Plant and Equipment, Policy [Policy Text Block]	Property and Equipment Property and equipment is presented net of accumulated depreciation of approximately $11.9 million and $11.6 million as of June 30, 2017 and December 31, 2016 , respectively.
