	Organization and Nature of the Business

("Manning & Napier" or the "Company") provides a broad range of investment solutions through separately managed accounts, mutual funds, and collective investment trust funds, as well as a variety of consultative services that complement its investment process. Founded in 1970, the Company offers equity and fixed income portfolios as well as a range of blended asset portfolios, such as life cycle funds, that use a mix of stocks and bonds. Headquartered in Fairport, New York, the Company serves a diversified client base of high net worth individuals and institutions, including 401(k) plans, pension plans, Taft-Hartley plans, endowments and foundations.
	The Company was incorporated on June 22, 2011 for the purpose of facilitating an initial public offering ("IPO") of 13,583,873 shares of its Class A common stock and to become the sole managing member of Manning & Napier Group, LLC and its subsidiaries (“Manning & Napier Group”), a holding company for the investment management businesses conducted by its operating subsidiaries. Prior to the series of transactions to reorganize the capital structure in advance of the IPO, the Company was a group of privately-held, affiliated companies (the "Manning & Napier Companies"). The diagram below depicts the Company's organization structure as of December 31, 2013.
	-1	Manning & Napier, Inc. is the managing member of Manning & Napier Group.

	Summary of Significant Accounting Policies
	Basis of Presentation
	The accompanying 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 (the "SEC"). All material intercompany transactions have been eliminated in consolidation.
	In the quarter ended March 31, 2013, the Company changed the presentation of certain items within its consolidated statements of operations. The Company incurs 12b-1 distribution and servicing fees ("12b-1 fees") that are due to third party distributors of the Manning & Napier Fund, Inc. series of mutual funds (the "Fund") based on the assets under management of designated share classes of the Fund. The Company incurs sub-custodian fees due to a third party that provides custodial services for those assets where Exeter Trust Company is the named custodian. The Company changed its presentation of 12b-1 fees and sub-custodian fees from "Other operating costs" to "Sub-transfer agent and shareholder service costs" to more appropriately reflect the nature of these costs as distribution and asset-based. The line was renamed "Distribution, servicing and custody expenses" to reflect the broader nature of the underlying expenses. In the year ended December 31, 2013, the Company changed its presentation of "Changes in amounts payable under the tax receivable agreement" from "Other operating costs" to a separate component of "Non-operating income (loss)".
	Amounts for the comparative prior fiscal year periods have been reclassified to conform to the current year presentation. These reclassifications had no impact on previously reported net income or financial position and do not represent a restatement of any previously published financial results. The impact is illustrated below:
		Year Ended December 31,

	Other operating costs, as reclassified	$	31,145		$	28,373
	Use of Estimates
	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
	Manning & Napier holds approximately 14% economic interest 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 M&N Group Holdings, LLC (“M&N Group Holdings”) and Manning & Napier Capital Company, LLC (“MNCC”).
	For periods prior to the reorganization, the financial statements include the combined accounts of the Manning & Napier Companies.
	All material intercompany transactions have been eliminated in consolidation.
	Operating Segments
	The Company operates in one segment, the investment management industry. The Company primarily provides investment management services to separately managed accounts, mutual funds and collective investment trust funds. Management assesses the financial performance of these vehicles on a combined basis.
	Advisory Agreements
	The Company derives significant revenue from its role as advisor to the Manning & Napier Fund Inc. series of mutual funds (“Fund”) and the Exeter Collective Investment Trust (“CIT”) investment vehicles.
	Investments in the Fund amounted to approximately $1.7 million and $0.2 million at December 31, 2013 and 2012, respectively.
	Fees earned for advisory related services provided to the Fund and CIT investment vehicles were approximately $196.9 million, $173.4 million and $167.8 million for the years ended December 31, 2013, 2012 and 2011, respectively, which represents greater than 10% of revenue in each period.
	Cash and Cash Equivalents
	The Company 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 mutual funds. 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.
	Due from broker
	The Company conducts business with brokers for certain of its investment activities. The due from broker balance on the consolidated statements of financial condition represents cash held by brokers as collateral for managed futures and cash at brokers as collateral for securities sold, not yet purchased.
	Investment Securities
	Investment securities are classified as either trading 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 on investments in the consolidated statements of operations. Realized gains and losses on sales of trading securities are computed on a specific identification basis. At December 31, 2013 and 2012, trading securities consist solely of investments held by the Company for the purpose of providing initial cash seeding for product development purposes.
	Investment securities classified as available-for-sale consist of U.S. Treasury notes. 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 on investments in the consolidated statements of operations.
	Securities sold, not yet purchased are recorded on the trade date, are stated at fair value and represent obligations of the Company to purchase the securities at prevailing market rates. Therefore, the future satisfaction of such obligations may be for an amount greater or less than the amounts recorded on the consolidated statements of financial condition. The ultimate gains or losses recognized are dependent upon the prices at which these securities are purchased to settle the obligations under the sales commitments. Realized gains and losses from covers of securities sold, not yet purchased transactions are included in net capital gain (loss) from investments on the consolidated statements of operations. Securities sold, not yet purchased are included in accrued expenses and other liabilities in the consolidated statements of financial condition, with any unrealized gains or losses reported in current period earnings in net capital gain (loss) from investments on the consolidated statements of operations.
	Accounts Receivable
	Accounts receivable includes investment management and custodial fees receivable from clients. The Company’s accounts receivable balances do not include any significant allowance for doubtful accounts nor has any significant bad debt expense attributable to accounts receivable been recorded for the years ended December 31, 2013, 2012 or 2011.
	Property and Equipment
	Property and equipment are recorded at cost, less accumulated depreciation. Property and equipment are depreciated on a straight-line basis over the applicable life of the asset class. Depreciation is calculated for computer software, office equipment, and furniture and fixtures using useful lives of 3, 5, and 7 years, respectively. Leasehold improvements are depreciated over the shorter of the estimated useful life of the asset or the remaining expected lease term. Gains or losses upon sale or other disposition of fixed assets, are included in the consolidated statements of operations.
	Leases
	Rent under non-cancelable operating leases with scheduled rent increases is accounted for on a straight-line basis over the lease term, beginning on the date of initial possession or the effective date of the lease agreement. Allowances and other lease incentives provided by the Company’s landlords are amortized on a straight-line basis as a reduction of rent expense. The difference between straight-line rent expense and rent paid and the unamortized deferred lease costs and build-out allowances are recorded as deferred rent liability in the consolidated statements of financial condition.
	Revenue Recognition
	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. Revenue is also earned for providing custodial services, sub-advisor services to mutual funds and collective investment trusts and other services. For mutual funds and collective investment trust vehicles, the Company’s fees are calculated and earned daily based on AUM.
	All other revenue earned is recognized on a U.S. GAAP accounting basis as earned per the terms of the specific contract.
	Equity-Based Compensation
	The Company measures the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. The cost is recognized over the period during which an employee is required to provide service in exchange for the award. The Company estimates an expected forfeiture rate, and only recognize expense for those awards expected to vest. If the actual forfeiture rate is materially different from that estimated, the equity-based compensation expense could be significantly different from the amount initially recorded in the current period. See Note 13 for additional information on equity-based compensation.
	Income Taxes
	The Company records a tax provision for the anticipated tax consequences of the reported results of operations. The provision for income taxes is computed using the asset and liability method, under which deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax basis of assets and liabilities, and for operating losses and tax credit carryforwards. Deferred tax assets and liabilities are measured using the currently enacted tax rates that apply to taxable income in effect for the years in which those tax assets are expected to be realized or settled. The Company records a valuation allowance, if necessary, to reduce deferred tax assets to the amount that is believed more likely than not to be realized.
	The Company recognizes tax benefits from uncertain tax positions only if it is more likely than not that the tax position will be sustained upon examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement.
	Comprehensive Income (Loss)
	Comprehensive income is a measure of income which includes net income (loss) and other comprehensive income (loss). Other comprehensive income (loss) consists of the change in unrealized gains and losses on available-for-sale investments. The changes in the balances of components comprising other comprehensive income (loss) are presented in the accompanying consolidated statements of comprehensive income for the years ended December 31, 2013, 2012 and 2011.
	Loss Contingencies
	The Company accrues for estimated costs, including legal costs related to existing lawsuits, claims and proceedings when it is probable that a liability has been incurred and the costs can be reasonably estimated. Potential loss contingencies and related accruals are reviewed at least quarterly and are adjusted to reflect the impact and status of settlements, rulings, advice of counsel and other information pertinent to a particular matter. Significant differences could exist between the actual cost required to investigate, litigate and/or settle a claim or the ultimate outcome of a suit and management’s estimate. These differences could have a material impact on the Company’s consolidated financial statements. No loss accruals were recorded as of December 31, 2013, 2012 and 2011.
	Recent Accounting Pronouncements
	In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. This new guidance requires entities to present (either on the face of the income statement or in the notes) the effects on the line items of the income statement for amounts reclassified out of Accumulated Other Comprehensive Income. The adoption of this amendment on January 1, 2013 did not have a material impact on the consolidated financial statements and related disclosures.
	In December 2011, the FASB issued ASU 2011-11, Disclosures about Offsetting Assets and Liabilities. The amended standard requires an entity to disclose information about offsetting and related arrangements to enable users of its financial statements to understand the effect of those arrangements on its financial position. The adoption of this standard effective January 1, 2013 did not have a material impact on the consolidated financial statements.

Noncontrolling Interest [Abstract]	'
Noncontrolling Interests	'
	Noncontrolling Interests
	Manning & Napier holds an approximately 14% economic interest 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 conditions with respect to the remaining approximately 86% economic interest in Manning & Napier Group held by M&N Group Holdings and MNCC. Net income (loss) attributable to noncontrolling interests on the consolidated statements of operations represents the portion of earnings or loss attributable to the economic interest in Manning & Napier Group held by the noncontrolling interests. Subsequent to the IPO, the Company has consolidated the results of Manning & Napier Group; therefore, all income for the period prior to the IPO is entirely attributable to noncontrolling interests.
	The following provides a reconciliation from “Income (loss) before provision for income taxes” to “Net income (loss) attributable to Manning & Napier, Inc.”:
		Year Ended December 31,
		2013			2012			2011
		(in thousands)
	Income (loss) before provision for income taxes	$	86,069		$	84,579		$	(104,434	)

	Less: loss before provision for income taxes of Manning & Napier, Inc. (b)	(937		)	(1,773		)	(298		)
	Income (loss) before provision for income taxes, as adjusted	87,006			86,352			(196,502		)

	Net income (loss) attributable to controlling interest	12,103			11,929			(25,836		)
	Plus: loss before provision for income taxes of Manning & Napier, Inc. (b)	(937		)	(1,773		)	(298		)
	Income (loss) before income taxes attributable to Manning & Napier, Inc.	11,166			10,156			(26,134		)
	Less: provision for income taxes of Manning & Napier, Inc. (d)	8,510			7,687			1,033
	Net income (loss) attributable to Manning & Napier, Inc.	$	2,656		$	2,469		$	(27,167	)
	__________________________
	a)	All income for the period prior to the IPO is entirely attributable to the noncontrolling interests which existed prior to the IPO.
	b)	Manning & Napier, Inc. incurs certain expenses that are only attributable to it and are therefore excluded from the net income (loss) attributable to noncontrolling interests.
	c)	Income (loss) 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. For the 2011 period, the amount of loss attributable to Manning & Napier, Inc. from the date of the IPO through December 31, 2011 represents the Company’s weighted ownership of Manning & Napier Group during that period.
	d)	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 totaled approximately $9.1 million, $8.2 million and $2.0 million for the years ended December 31, 2013, 2012 and 2011, respectively.
	On March 29, 2013, M&N Group Holdings exchanged 498,497 Class A units of Manning & Napier Group for approximately $7.4 million in cash, $6.5 million of which was attributable to the noncontrolling interests. Subsequent to the exchange, the Class A units were retired. In addition, as further described in Note 13, on April 30, 2013 40,480 units of Manning & Napier Group were redeemed and re-issued as Class A common stock and 9,893 shares of Class A common stock were granted resulting in Manning & Napier, Inc. acquiring an additional 50,373 Class A units of Manning & Napier Group. As a result of the aforementioned transactions, the Company's economic ownership interest in Manning & Napier Group increased to approximately 14%. As of December 31, 2013, M&N Group Holdings and MNCC may exchange 75,861,023 Class A units of Manning & Napier Group for shares of the Company's Class A common stock pursuant to the terms of the exchange agreement entered into at the time of the IPO.
	Pursuant to the exchange agreement (Note 11) and following the 2011 consummation of the IPO, Class A units of Manning & Napier Group were acquired from their holders in exchange for cash or shares of the Company’s Class A common stock. In addition, approximately $105.7 million of the net proceeds of the initial public offering were used to purchase Class A units of Manning & Napier Group held by M&N Group Holdings. Manning & Napier Group has elected Section 754 of the Internal Revenue Code, as amended, to be in effect for taxable years in which purchases or exchanges of the Class A units of Manning & Napier Group will occur. Pursuant to the Section 754 election, each future purchase or exchange of such Class A units is expected to result in the purchaser of such units receiving an increase in the tax basis of tangible and intangible assets of Manning & Napier Group. The basis adjustments will increase, for tax purposes, the tax basis in the Manning & Napier Group’s assets attributable to the Class A units acquired. The higher tax basis will increase depreciation and amortization deductions allocable to the Company from Manning & Napier Group and therefore reduce the amount of income tax that the Company would otherwise be required to pay in the future.
	Upon the consummation of the IPO, a tax receivable agreement ("TRA") was entered into between the Company and the other holders of Manning & Napier Group, pursuant to which the Company 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 the Company actually realizes, or is deemed to realize in certain circumstances, as a result of any step-up in tax basis in Manning & Napier Group’s assets resulting from (i) the Company’s purchase of such Class A units from M&N Group Holdings with a portion of the net proceeds of the initial public offering, (ii) the Company’s purchases or exchanges of such Class A units from M&N Group Holdings and MNCC respectively, for cash or, at the Company’s election, shares of its Class A common stock and (iii) payments under the tax receivable agreement, including any tax benefits related to imputed interest deemed to be paid by the Company as a result of such agreement.
	There is a possibility that not all of the 85% of the applicable cash savings will be paid to the selling or exchanging holder of Class A units at the time described above. If it is determined that all or a portion of such applicable tax savings is in doubt, payment to such holders of Class A units will be the amount attributable to the portion of the applicable tax savings that are determined not to be in doubt and the payment of the remainder at such time as it is reasonably determined that the actual tax savings or that the amount is no longer in doubt.
	At December 31, 2013 and 2012, the Company had recorded a total liability of $44.0 million and $45.9 million, respectively, representing the payments due to the selling unit holders under the TRA. Of these amounts, $2.0 million and $1.9 million were included in accrued expenses and other liabilities at December 31, 2013 and 2012, respectively. Payments are anticipated to be made annually over 15 years, commencing from the date of each event that gives rise to the TRA benefits, beginning with the date of the 2011 initial public offering. The payments are made in accordance with the terms of the TRA. The timing of the payments is subject to certain contingencies including the Company having sufficient taxable income to utilize all of the tax benefits defined in the TRA. Payments pursuant to the TRA for the year ended December 31, 2013 and 2012 totaled $2.0 million and $0.3 million, respectively, while the Company made no payments for the year ended December 31, 2011.
	During the years ended December 31, 2013 and 2012, the Company made approximately $120.9 million and $108.1 million, respectively, in distributions to noncontrolling interests. None of these distributions were payments pursuant to the TRA.
	Obligations pursuant to the TRA are obligations of the Company. They do not impact the noncontrolling interests. These obligations are not income tax obligations and have no impact on the tax provision or the allocation of taxes. Furthermore, the TRA has no impact on the allocation of the provision for income taxes to the Company’s net income (loss).

	Investment securities are classified as either trading 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. At December 31, 2013 and 2012, trading securities consist solely of investments held by the Company to provide initial cash seeding for product development purposes. The Company recognized approximately $0.9 million of net unrealized gains, less than $0.1 million of net unrealized losses and less than $0.1 million of net unrealized gains related to investments classified as trading securities for the years ended December 31, 2013, 2012 and 2011, respectively.

	Derivative Instruments
	The Company enters into futures contracts for product development purposes. Futures are commitments either to purchase or sell a designated financial instrument, currency, commodity or an index at a specified future date for a specified price and may be settled in cash or another financial asset. Upon entering into a futures contract, the Company is required to pledge to the broker an amount of cash, which is reported in due from broker within the consolidated statements of financial condition. Futures contracts have little credit risk because the counterparties are futures exchanges. The Company does not hold any derivatives in a formal hedge relationship under ASC 815-10, Derivatives and Hedging.
	The following tables present the notional value and fair value as of December 31, 2013 for derivative instruments not designated as hedging instruments:

	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 assets as of December 31, 2013 and 2012:
		31-Dec-13
		Level 1		Level 2		Level 3		Totals

	Total assets at fair value	$	7,504	$	5,578	$	—	$	13,082
	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.
	There were no Level 3 securities held by the Company as of December 31, 2013 or 2012.
	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 significant transfers between Level 1 and Level 2 during the years ended December 31, 2013, 2012 and 2011.

	Commitments and Contingencies
	The Company may 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.
	As an investment adviser to a variety of investment products, the Company is subject to routine reviews and inspections by the SEC and Financial Industry Regulatory Authority, Inc., or FINRA. 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 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. Currently, there are no legal proceedings pending or to the Company’s knowledge threatened against it. As of December 31, 2013 and 2012, the Company has not accrued for any such claims, legal proceedings, or other contingencies.
	Lease Commitments
	The Company has several operating leases for office space, and leases its primary office facilities in Fairport, New York under an operating lease expiring December 31, 2022.

	Basic earnings per share (“basic EPS”) is computed by dividing net income by the weighted average number of shares outstanding for the reporting period. Diluted earnings per share (“diluted EPS”) gives effect during the reporting period to other potentially dilutive shares outstanding. The following is a reconciliation of the income and share data used in the basic and diluted earnings per share computations for the years ended December 31, 2013 and 2012 and for the period from November 18, 2011 through December 31, 2011:

	2011 Equity Compensation Plan
	The 2011 Equity Compensation Plan (the “2011 Plan”) was adopted by the Company’s board of directors and approved by the Company’s stockholders prior to the consummation of the IPO. At December 31, 2013, a total of 12,675,523 equity interests remain available for issuance under the 2011 Plan. The equity interests may be issued in the form of the Company’s Class A common stock, restricted stock units, units of Manning & Napier Group, or certain classes of membership interests in the Company which may convert into units of Manning & Napier Group ("LTIP units").
	On April 30, 2013, 467,290 interests were awarded under the 2011 Plan. Of these awards, 40,480 related to the redemption of previously issued and outstanding profit participation units in Manning & Napier Group that were granted prior to the initial public offering, which were subsequently re-issued as Class A common stock. The remaining 426,810 awards represent newly issued awards, consisting of 9,893 shares of Class A common stock and 416,917 of restricted stock units. The Class A common stock awards vested immediately and the restricted stock units will generally vest on the third anniversary of the grant date.
	The following table summarizes stock award activity for the year ended December 31, 2013 under the 2011 Plan:
			Restricted			Weighted Average Grant Date Fair Value
			Stock Awards
	Stock awards outstanding at January 1, 2013		—			$	—
	Granted		467,290			$	15.83

	Forfeited		—			—
	Stock awards outstanding at December 31, 2013		416,917			$	15.63
	The weighted average fair value of 2011 Plan awards granted during the year ended December 31, 2013 was $15.83, based on the closing sale price of Manning & Napier Inc.'s Class A common stock as reported on the New York Stock Exchange on the date of grant, and reduced by the present value of the dividends expected to be paid on the underlying shares during the requisite service period. For such awards that vest over time, recipients are not entitled to dividends declared on the underlying Class A common shares until the awards become fully vested.
	For the year ended December 31, 2013, the Company recorded approximately $1.7 million of compensation expense, respectively, related to awards under the 2011 Plan. The aggregate intrinsic value of 2011 Plan awards that vested during the year ended December 31, 2013 was approximately $0.9 million. As of December 31, 2013, there was unrecognized compensation expense related to 2011 Plan awards of approximately $5.0 million, which the Company expects to recognize over a weighted average period of approximately 2.3 years.
	2011 Reorganization-Related Transactions
	In connection with the 2011 reorganization transactions, Class B units of M&N Group Holdings were granted to William Manning as part of the overall agreement among William Manning and the other owners of the Manning & Napier Companies to consummate the reorganization. These Class B units were vested immediately upon the consummation of the IPO. As such, a one-time compensation charge of $213.0 million was recognized by the Company in 2011, based on the value of these units.
	Also upon the consummation of the IPO, the Company adopted new vesting terms related to the pre-IPO ownership interests of certain employees of the Company other than William Manning. Such individuals were entitled to 15% of their pre-reorganization ownership interests upon the consummation of the IPO, with an additional 5% of such ownership interests vesting annually through 2014, provided such individuals are employees of the Company as of such date (service-based vesting). The remaining ownership interests will be subject to performance-based vesting annually through 2014, to be determined by a vesting committee, and subject to an initial two-year lockup period as well as other selling restrictions (performance-based vesting). Notwithstanding these vesting requirements, in the event William Manning sells any portion of his interests in the Manning & Napier Companies following the consummation of the initial public offering, the other pre-IPO employee-owners will have the right to sell a pro rata amount of such individuals’ indirect ownership interest in Manning & Napier Group, and if any individual does not at such time have fully vested ownership interests sufficient to allow such participation, an amount of their ownership interests will vest to the extent necessary to allow them to participate in the pro rata sale. In connection with the reorganization and the related amendment to the limited liability company agreement of Manning & Napier Group, these pre-IPO ownership interests were reclassified as Class A Units of Manning & Napier Group. As such, fully vested ownership interests may be exchangeable for shares of the Company’s Class A common stock (Note 11).
	Reorganization-Related Equity Compensation
	During 2013, the Company recorded compensation expense for the approximately 3.8 million performance-based awards eligible to vest on December 31, 2013 under the vesting terms of ownership interests in connection with the 2011 reorganization transactions. Vesting of these performance-based awards was contingent upon the satisfaction of annual performance criteria specific to each award recipient. The determination of whether an award recipient met such performance criteria was made by a vesting committee at the end of the annual service period, and resulted in a total of 3.4 million awards vesting on December 31, 2013. In accordance with Accounting Standards Codification Topic 718, Stock Compensation, the grant date for these performance-based awards occurred at the end of the service period. Prior to the grant date, compensation expense was re-measured at the end of each reporting period, to the extent that service has been rendered in proportion to the total requisite service period. No expense is being recognized for the performance-based awards eligible to vest on December 31, 2014, as the performance conditions have not yet been defined.
	The following table summarizes performance-based stock unit activity for the year ended December 31, 2013 specific to the 2011 reorganization transactions:
		Performance-Based Stock Units			Weighted Average Grant Date Fair Value
	Stock unit awards outstanding at January 1, 2013	28,914			$	12

	The following table summarizes service-based stock unit activity for the year ended December 31, 2013 specific to the 2011 reorganization transactions:
		Service-Based Stock Units			Weighted Average Grant Date Fair Value

	Forfeited	(8,853	)		$	12
	Stock unit awards outstanding at December 31, 2013	1,458,049			$	12
	For performance-based and service-based awards granted during the year ended December 31, 2013, the weighted average fair value of the awards granted was $17.65 and $16.54, respectively, as determined by the closing sale price of Manning & Napier, Inc.’s Class A common stock as reported on the New York Stock Exchange on the date of grant.
	For the year ended December 31, 2013, the Company recorded approximately $81.2 million of compensation expense related to the vesting terms of ownership interests in connection with the 2011 reorganization transactions. For the year ended December 31, 2013, approximately $19.6 million is attributable to the service-based awards. For the same period, the remaining expense of approximately $61.6 million is attributable to performance-based awards. For the year ended December 31, 2013, $60.8 million of the expense attributable to performance-based awards is related to awards that vested on December 31, 2013 under the vesting terms of ownership interests in connection with the 2011 reorganization transactions. As discussed above, this expense is based upon the closing sale price of Manning & Napier Inc.’s Class A common stock as reported on the New York Stock Exchange on December 31, 2013.
	For the year ended December 31, 2012, the Company recorded approximately $72.3 million of compensation expense related to the vesting terms of ownership interests in connection with the 2011 reorganization transactions. For the year ended December 31, 2012, approximately $18.4 million is attributable to the service-based awards. For the same period, the remaining expense of approximately $53.8 million is attributable to performance-based awards. For the year ended December 31, 2012, $53.1 million of the expense attributable to performance-based awards is related to awards that vested on December 31, 2012 under the vesting terms of ownership interests in connection with the 2011 reorganization transactions. As discussed above, this expense is based upon the closing sale price of Manning & Napier Inc.’s Class A common stock as reported on the New York Stock Exchange on December 31, 2012.
	For the year ended December 31, 2011, the Company recorded approximately $0.9 million of compensation expense related to shares granted prior to the IPO as well as $215.3 million of compensation expense related to the amended vesting terms of ownership interests described above. Of this amount, $213.0 million was a one-time compensation charge related to the fully vested Class B Units of M&N Group Holdings granted to William Manning.
	The aggregate intrinsic value of service-based and performance-based stock units that vested during the year ended December 31, 2013 was approximately $26.1 million and $61.9 million, respectively. The aggregate intrinsic value of service-based and performance-based stock units that vested during the year ended December 31, 2012 was approximately $19.3 million and $53.7 million, respectively. The aggregate intrinsic value of stock units that vested during the year ended December 31, 2011 was approximately $213.9 million.
	As of December 31, 2013, there was unrecognized compensation expense related to unvested service-based awards of approximately $15.7 million. The Company expects to recognize this expense over a weighted average period of 0.9 years.
	As of December 31, 2013, there was unrecognized compensation expense related to unvested performance-based awards of approximately $73.4 million, which the Company expects to recognize over a weighted average period of 1.0 years. Included in this total is an estimate of $72.7 million of unrecognized compensation expense related to the approximately 4.2 million unvested performance-based awards under the vesting terms of ownership interests in connection with the 2011 reorganization transactions. This estimate is based upon the closing sale price of Manning & Napier, Inc.’s Class A common stock as reported on December 31, 2013, and includes performance awards eligible to vest through 2014.
	Stock unit awards forfeited during the year ended December 31, 2013 were redistributed amongst the legacy owners, including William Manning. Of the stock units forfeited, 102,390 were granted to William Manning which vested immediately. The remaining units were awarded to the other legacy owners and are subject to performance criteria. This award does not result in dilution to the number of outstanding shares of Class A common stock. The aggregate intrinsic value of these stock units that vested during the year ended December 31, 2013 was approximately $1.7 million.

	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 and local income taxes on their earnings, as such 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, state and local income taxes on their earnings and losses, respectively.
	Components of the provision for income taxes consist of the following:

	Provision for income taxes	$	9,128		$	8,160		$	1,982
	The provision for income taxes includes a (benefit) provision 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. This (favorable) unfavorable impact is partially offset by the impact of certain permanent items, primarily attributable to certain compensation related expenses that are not deductible for tax purposes.

	The decrease in net deferred tax assets as of December 31, 2013 since December 31, 2012 was primarily attributable to amortization of the tangible and intangible assets of Manning & Napier Group. During the year ended December 31, 2011, the Company recorded the tax basis of the tangible and intangible assets of Manning & Napier Group in accordance with the Company’s election made under Section 754 of the Internal Revenue Code. Upon consummation of the initial public offering, the Company entered into an exchange agreement whereby interests of Manning & Napier Group were exchanged for Class A shares. This transaction resulted in an increase in the tax basis of the tangible and intangible assets of Manning & Napier Group, which triggered a liability under the tax receivable agreement. The agreement provides for a payment to the Manning & Napier Group selling unit holders of 85% of the cash tax savings (if any) of the Company, resulting from the increased tax benefits from the exchange and for the Company to retain 15% of such benefits.
	As of December 31, 2013 and 2012, the Company had no available net operating loss carryforwards for income tax purposes.
	The Company has assessed the recoverability of the deferred tax assets and believes it is more likely than not that the assets will be realized. The Company has not recorded a valuation allowance as of December 31, 2013 and 2012.
	Accounting for Uncertainty in Income Taxes
	The Company's liability for income taxes associated with unrecognized tax benefits of $3.1 million was unchanged during the years ended December 31, 2013 and 2012.
	The Company’s policy regarding interest and penalties related to uncertain tax positions is to recognize such items as a component of the provision for income taxes. The Company recorded less than $0.1 million in interest and no penalties in the consolidated statements of operations for the year ended December 31, 2013, and no interest or penalties in the years ended December 31, 2012 and 2011.
	The Company does not expect that changes in the liability for unrecognized tax benefits during the next twelve months will have a significant impact on the Company's financial position or results of operations. If the unrecognized tax benefits of $3.1 million were subsequently recognized, it would favorably affect the effective income tax rate in the period recognized.
	The Company files income tax returns with Federal, state and local jurisdictions. The Company’s U.S. Federal and state tax matters for the years 2010 through 2012 remain subject to examination by the respective tax authorities.

Summary_of_Significant_Account1

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2013
Accounting Policies [Abstract]	'
Basis of Presentation	'
	Basis of Presentation
	The accompanying 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 (the "SEC"). All material intercompany transactions have been eliminated in consolidation.
	In the quarter ended March 31, 2013, the Company changed the presentation of certain items within its consolidated statements of operations. The Company incurs 12b-1 distribution and servicing fees ("12b-1 fees") that are due to third party distributors of the Manning & Napier Fund, Inc. series of mutual funds (the "Fund") based on the assets under management of designated share classes of the Fund. The Company incurs sub-custodian fees due to a third party that provides custodial services for those assets where Exeter Trust Company is the named custodian. The Company changed its presentation of 12b-1 fees and sub-custodian fees from "Other operating costs" to "Sub-transfer agent and shareholder service costs" to more appropriately reflect the nature of these costs as distribution and asset-based. The line was renamed "Distribution, servicing and custody expenses" to reflect the broader nature of the underlying expenses. In the year ended December 31, 2013, the Company changed its presentation of "Changes in amounts payable under the tax receivable agreement" from "Other operating costs" to a separate component of "Non-operating income (loss)".
	Amounts for the comparative prior fiscal year periods have been reclassified to conform to the current year presentation. These reclassifications had no impact on previously reported net income or financial position and do not represent a restatement of any previously published financial results.
Use of Estimates	'
	Use of Estimates
	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
	Manning & Napier holds approximately 14% economic interest 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 M&N Group Holdings, LLC (“M&N Group Holdings”) and Manning & Napier Capital Company, LLC (“MNCC”).
	For periods prior to the reorganization, the financial statements include the combined accounts of the Manning & Napier Companies.
	All material intercompany transactions have been eliminated in consolidation.
Operating Segments	'
	Operating Segments
	The Company operates in one segment, the investment management industry. The Company primarily provides investment management services to separately managed accounts, mutual funds and collective investment trust funds. Management assesses the financial performance of these vehicles on a combined basis.
Advisory Agreements	'
	Advisory Agreements
	The Company derives significant revenue from its role as advisor to the Manning & Napier Fund Inc. series of mutual funds (“Fund”) and the Exeter Collective Investment Trust (“CIT”) investment vehicles.
	Investments in the Fund amounted to approximately $1.7 million and $0.2 million at December 31, 2013 and 2012, respectively.
	Fees earned for advisory related services provided to the Fund and CIT investment vehicles were approximately $196.9 million, $173.4 million and $167.8 million for the years ended December 31, 2013, 2012 and 2011, respectively, which represents greater than 10% of revenue in each period.
Cash and Cash Equivalents	'
	Cash and Cash Equivalents
	The Company 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 mutual funds
Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy	'
	Due from broker
	The Company conducts business with brokers for certain of its investment activities. The due from broker balance on the consolidated statements of financial condition represents cash held by brokers as collateral for managed futures and cash at brokers as collateral for securities sold, not yet purchased.
Investment Securities	'
	Investment Securities
	Investment securities are classified as either trading 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 on investments in the consolidated statements of operations. Realized gains and losses on sales of trading securities are computed on a specific identification basis. At December 31, 2013 and 2012, trading securities consist solely of investments held by the Company for the purpose of providing initial cash seeding for product development purposes.
	Investment securities classified as available-for-sale consist of U.S. Treasury notes. 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 on investments in the consolidated statements of operations.
	Securities sold, not yet purchased are recorded on the trade date, are stated at fair value and represent obligations of the Company to purchase the securities at prevailing market rates. Therefore, the future satisfaction of such obligations may be for an amount greater or less than the amounts recorded on the consolidated statements of financial condition. The ultimate gains or losses recognized are dependent upon the prices at which these securities are purchased to settle the obligations under the sales commitments. Realized gains and losses from covers of securities sold, not yet purchased transactions are included in net capital gain (loss) from investments on the consolidated statements of operations. Securities sold, not yet purchased are included in accrued expenses and other liabilities in the consolidated statements of financial condition, with any unrealized gains or losses reported in current period earnings in net capital gain (loss) from investments on the consolidated statements of operations.
Accounts Receivable	'
	Accounts Receivable
	Accounts receivable includes investment management and custodial fees receivable from clients. The Company’s accounts receivable balances do not include any significant allowance for doubtful accounts nor has any significant bad debt expense attributable to accounts receivable been recorded for the years ended December 31, 2013, 2012 or 2011.
Property and Equipment	'
	Property and Equipment
	Property and equipment are recorded at cost, less accumulated depreciation. Property and equipment are depreciated on a straight-line basis over the applicable life of the asset class. Depreciation is calculated for computer software, office equipment, and furniture and fixtures using useful lives of 3, 5, and 7 years, respectively. Leasehold improvements are depreciated over the shorter of the estimated useful life of the asset or the remaining expected lease term. Gains or losses upon sale or other disposition of fixed assets, are included in the consolidated statements of operations.
Leases	'
	Leases
	Rent under non-cancelable operating leases with scheduled rent increases is accounted for on a straight-line basis over the lease term, beginning on the date of initial possession or the effective date of the lease agreement. Allowances and other lease incentives provided by the Company’s landlords are amortized on a straight-line basis as a reduction of rent expense. The difference between straight-line rent expense and rent paid and the unamortized deferred lease costs and build-out allowances are recorded as deferred rent liability in the consolidated statements of financial condition.
Revenue Recognition	'
	Revenue Recognition
	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. Revenue is also earned for providing custodial services, sub-advisor services to mutual funds and collective investment trusts and other services. For mutual funds and collective investment trust vehicles, the Company’s fees are calculated and earned daily based on AUM.
	All other revenue earned is recognized on a U.S. GAAP accounting basis as earned per the terms of the specific contract.
Equity-Based Compensation	'
	Equity-Based Compensation
	The Company measures the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. The cost is recognized over the period during which an employee is required to provide service in exchange for the award. The Company estimates an expected forfeiture rate, and only recognize expense for those awards expected to vest. If the actual forfeiture rate is materially different from that estimated, the equity-based compensation expense could be significantly different from the amount initially recorded in the current period. See Note 13 for additional information on equity-based compensation.
Income Taxes	'
	Income Taxes
	The Company records a tax provision for the anticipated tax consequences of the reported results of operations. The provision for income taxes is computed using the asset and liability method, under which deferred tax assets and liabilities are recognized for the expected future tax consequences of temporary differences between the financial reporting and tax basis of assets and liabilities, and for operating losses and tax credit carryforwards. Deferred tax assets and liabilities are measured using the currently enacted tax rates that apply to taxable income in effect for the years in which those tax assets are expected to be realized or settled. The Company records a valuation allowance, if necessary, to reduce deferred tax assets to the amount that is believed more likely than not to be realized.
	The Company recognizes tax benefits from uncertain tax positions only if it is more likely than not that the tax position will be sustained upon examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement.
Comprehensive Income (Loss)	'
	Comprehensive Income (Loss)
	Comprehensive income is a measure of income which includes net income (loss) and other comprehensive income (loss). Other comprehensive income (loss) consists of the change in unrealized gains and losses on available-for-sale investments. The changes in the balances of components comprising other comprehensive income (loss) are presented in the accompanying consolidated statements of comprehensive income for the years ended December 31, 2013, 2012 and 2011.
Loss Contingencies	'
	Loss Contingencies
	The Company accrues for estimated costs, including legal costs related to existing lawsuits, claims and proceedings when it is probable that a liability has been incurred and the costs can be reasonably estimated. Potential loss contingencies and related accruals are reviewed at least quarterly and are adjusted to reflect the impact and status of settlements, rulings, advice of counsel and other information pertinent to a particular matter. Significant differences could exist between the actual cost required to investigate, litigate and/or settle a claim or the ultimate outcome of a suit and management’s estimate. These differences could have a material impact on the Company’s consolidated financial statements. No loss accruals were recorded as of December 31, 2013, 2012 and 2011.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements
	In February 2013, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2013-02, Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income. This new guidance requires entities to present (either on the face of the income statement or in the notes) the effects on the line items of the income statement for amounts reclassified out of Accumulated Other Comprehensive Income. The adoption of this amendment on January 1, 2013 did not have a material impact on the consolidated financial statements and related disclosures.
	In December 2011, the FASB issued ASU 2011-11, Disclosures about Offsetting Assets and Liabilities. The amended standard requires an entity to disclose information about offsetting and related arrangements to enable users of its financial statements to understand the effect of those arrangements on its financial position. The adoption of this standard effective January 1, 2013 did not have a material impact on the consolidated financial statements.

Reconciliation from Income Before Provision for Income Taxes to Net Income Attributable to Manning & Napier, Inc.	'
	The following provides a reconciliation from “Income (loss) before provision for income taxes” to “Net income (loss) attributable to Manning & Napier, Inc.”:
		Year Ended December 31,
		2013			2012			2011
		(in thousands)
	Income (loss) before provision for income taxes	$	86,069		$	84,579		$	(104,434	)

	Less: provision for income taxes of Manning & Napier, Inc. (d)	8,510			7,687			1,033
	Net income (loss) attributable to Manning & Napier, Inc.	$	2,656		$	2,469		$	(27,167	)
	__________________________
	a)	All income for the period prior to the IPO is entirely attributable to the noncontrolling interests which existed prior to the IPO.
	b)	Manning & Napier, Inc. incurs certain expenses that are only attributable to it and are therefore excluded from the net income (loss) attributable to noncontrolling interests.
	c)	Income (loss) 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. For the 2011 period, the amount of loss attributable to Manning & Napier, Inc. from the date of the IPO through December 31, 2011 represents the Company’s weighted ownership of Manning & Napier Group during that period.
	d)	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 totaled approximately $9.1 million, $8.2 million and $2.0 million for the years ended December 31, 2013, 2012 and 2011, respectively.
