Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Critical Accounting Policies The Company's critical accounting policies and estimates are disclosed in its Annual Report on Form 10-K for the year ended December 31, 2017 . The Company believes that the disclosures herein are adequate so that the information presented is not misleading; however, these financial statements should be read in conjunction with the financial statements and the notes thereto in the Company's Annual Report on Form 10-K for the year ended December 31, 2017 . The financial data for the interim periods may not necessarily be indicative of results for future interim periods or for the full year. Changes to the Company's accounting policies as a result of adopting ASU 2014-09, Revenue from Contracts with Customers (Topic 606) are discussed under "Revenue", "Costs to Obtain a Contract" and "Reclassifications" below. Revenue Investment Management: Investment management fees are computed as a percentage of assets under management ("AUM"). The Company's performance obligation is a series of services that form part of a single obligation satisfied over time. Separately managed accounts are paid in advance, typically for a semi-annual or quarterly period, or in arrears, typically for a monthly or quarterly period. When investment management fees are paid in advance, the Company defers the revenue as a contract liability and recognizes it over the applicable period. When investment management fees are paid in arrears, the Company estimates revenue and records a contract asset (accrued accounts receivable) based on AUM as of the most recent month end date. Mutual funds and collective investment trust investment management revenue is calculated and earned daily based on AUM. Revenue is presented net of cash rebates and fees waived pursuant to contractual expense limitations of the funds. The Company also has agreements with third parties who provide recordkeeping and administrative services for employee benefit plans participating in the collective investment trusts. The Company is acting as an agent on behalf of the employee benefit plan sponsors, therefore, investment management revenue is recorded net of fees paid to third party service providers. Distribution and shareholder servicing: The Company receives distribution and servicing fees for providing services to its affiliated mutual funds. Revenue is computed and earned daily based on a percentage of AUM. The performance obligation is a series of services that form part of a single performance obligation satisfied over time. The Company has agreements with third parties who provide distribution and administrative services for its mutual funds. The agreements are evaluated to determine whether revenue should be reported gross or net of payments to third-party service providers. The Company controls the services provided and acts as a principal in the relationship. Therefore, distribution and shareholder servicing revenue is recorded gross of fees paid to third parties. Custodial services: Custodial service fees are calculated as a percentage of the client’s market value with additional fees charged for certain transactions. For the safeguarding and administrative services that are subject to a percentage of market value fee, the Company's performance obligation is a series of services that form part of a single obligation satisfied over time. Revenue for transactions assigned a stand-alone selling price is recognized in the period which the transaction is executed. Custodial service fees are billed monthly in arrears. The Company has agreements with third parties who provide safeguarding, recordkeeping and administrative services for their clients. The Company controls the services provided and acts as a principal in the relationship. Therefore, custodial service revenue is recorded gross of fees paid to third parties. Costs to Obtain a Contract Incremental first year commissions directly associated with new separate account and collective investment trust contracts are capitalized and amortized straight-line over the estimated customer contract period of 7 years for separate accounts and 3 years for collective investment trust contracts. Refer to Note 3 for further discussion. 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. Reclassifications The Company changed the presentation of revenue within its consolidated statements of operations for the three and six months ended June 30, 2018 . Revenue, previously reported as a single line item, has been disaggregated to present revenue by the various services the Company provides. Amounts for the comparative prior periods have been reclassified to conform to the current period 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. For periods prior to and including December 31, 2017, the Company presented "Accounts receivable - affiliated mutual funds" on its consolidated statements of financial condition. Further disclosure regarding accounts receivable from affiliated mutual funds and the components of accounts receivable as of June 30, 2018 is included in "Accounts Receivable" in Note 3 of the notes to the consolidated financial statements. Amounts for the comparative prior fiscal year periods have been reclassified to conform to the current period presentation. These reclassifications had no impact on previously reported net income and do not represent a restatement of any previously published financial results. Principles of Consolidation The Company consolidates all majority-owned subsidiaries. In addition, as of June 30, 2018 , Manning & Napier holds an economic interest of approximately 18.2% 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”) and Rainier Multiple Investment Trust. The Fund, CIT and Rainier Multiple Investment Trust are legal entities, the business and affairs of which are managed by their respective boards of directors. As a result, each of these entities is a VOE. The Company holds, in limited cases, direct investments in a mutual fund (which are made on the same terms as are available to other investors) and consolidates each of these entities where it has a controlling financial interest or a majority voting interest. The Company's investments in the Fund amounted to approximately $1.4 million as of June 30, 2018 and $2.6 million as of December 31, 2017 . As of December 31, 2017 , the Company maintained significant influence in one mutual fund, Manning & Napier Fund, Inc. Quality Equity Series, but did not maintain a controlling financial interest in the mutual fund, which was accounted for as an equity method investment. During the first quarter of 2018, the Manning & Napier Fund, Inc. Quality Equity Series liquidated and closed. 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, 2018 , 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, corporate bonds 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 $11.7 million and $11.4 million as of June 30, 2018 and December 31, 2017 , 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 January 16, 2018, the Company sold a Rainier U.S. mutual fund to a third party for approximately $2.1 million , based on total assets under management on the closing date of approximately $0.3 billion . The carrying value of the intangible assets for client relationships associated with these products was zero as a result of the impairment loss recognized in 2016. During the first quarter of 2018, the Company recognized a gain of approximately $2.1 million for the sale of this fund, as included in other operating costs in the consolidated statements of operations. Operating Segments The Company operates in one segment, the investment management industry. Recently Adopted Accounting Pronouncements In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). The revenue standard contains principals to determine the measurement of revenue and timing of recognition and also impacts the accounting for incremental costs to obtain a contract. The Company adopted the new standard on its effective date of January 1, 2018. Refer to Note 3 for further discussion regarding the impact of adoption of this 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. The guidance is effective on January 1, 2018. The Company's adoption of ASU 2016-01 on January 1, 2018 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's adoption of ASU 2016-15 on January 1, 2018 did not have a material impact on its consolidated financial statements. Recent Accounting Pronouncements Not Yet Adopted 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 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. In February 2018, the FASB issued ASU No. 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income . The ASU requires a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the newly enacted federal corporate income tax rate as a result of the Tax Cuts and Jobs Act. The amount of the reclassification is the difference between the historical corporate income tax rate and the newly enacted 21% corporate income tax rate. The ASU will be effective for fiscal years beginning after December 15, 2018, with early adoption permitted. The Company is evaluating the effect of adopting this new accounting standard. |
