Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	Basis of Presentation and Significant Accounting Policies Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, these financial statements contain all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of the Company’s financial condition and results of operations. Operating results for the three and nine months ended September 30, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015. We have reclassified certain amounts in prior-period financial statements to conform to the current period's presentation. The condensed consolidated financial statements include the accounts of the Company, its subsidiaries and sponsored investment products in which it has a controlling financial interest, referred to as consolidated sponsored investment products or consolidated investment product. The Company is generally considered to have a controlling financial interest when it owns a majority of the voting interest in an entity or otherwise has the power to govern the financial and operating policies of the subsidiary. See Notes 13, 14 and 15 for additional information related to the consolidation of sponsored investment products and the investment product. Intercompany accounts and transactions have been eliminated. The Company also evaluates any variable interest entities (“VIEs”) in which the Company has a variable interest for consolidation. A VIE is an entity in which either (a) the equity investment at risk is not sufficient to permit the entity to finance its own activities without additional financial support or (b) where as a group, the holders of the equity investment at risk do not possess: (i) the power to direct the activities that most significantly impact the entity’s performance; (ii) the obligation to absorb expected losses or the right to receive expected residual returns of the entity; or (iii) proportionate voting and economic interests and where substantially all of the entity’s activities either involve or are conducted on behalf of the equity holders. If any entity has any of these characteristics, it is considered a VIE and is required to be consolidated by its primary beneficiary. The primary beneficiary is the entity that has both the power to direct the activities that most significantly impact the VIE’s economic performance and has the obligation to absorb losses of, or the right to receive benefits from, the VIE that could potentially be significant to the VIE. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014 filed with the Securities and Exchange Commission. The Company’s significant accounting policies, which have been consistently applied, are summarized in the 2014 Annual Report on Form 10-K. New Accounting Standards In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2015-03, Simplifying the Presentation of Debt Issuance Costs ("ASU2015-3"), which changes the presentation of debt issuance costs in the balance sheet. The new guidance requires that debt issuance costs be presented as a deduction from the carrying amount of the related debt rather than being presented as an asset. Amortization of debt issuance costs will continue to be reported as interest expense. In August 2015, the FASB issued ASU 2015-15 to amend ASU 2015-03 to address line-of-credit agreements. ASU 2015-15 allows entities to present debt issuance costs related to line-of-credit agreements as an asset and amortize deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings. The new guidance is effective for fiscal years and interim periods within those years beginning after December 15, 2015 and requires retrospective application for each prior period presented. Early adoption is permitted for financial statements that have not been previously issued. This standard is not expected to have a material impact on the Company's financial statements. In February 2015, the FASB issued ASU No. 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis (“ASU 2015-02”). This standard modifies existing consolidation guidance for reporting organizations that are required to evaluate whether they should consolidate certain legal entities. ASU 2015-02 is effective for fiscal years and interim periods within those years beginning after December 15, 2015 and requires either a retrospective or a modified retrospective approach to adoption. Early adoption is permitted. The Company is currently evaluating the potential impact of this standard on its financial statements, as well as the available transition methods. In August 2014, the FASB issued ASU No. 2014-13, Measuring the Financial Assets and Financial Liabilities of a Consolidated Collateralized Financing Entity (“CFE”) (“ASU 2014-13”). This new guidance requires reporting entities to use the more observable of the fair value of the financial assets or the financial liabilities to measure the financial assets and the financial liabilities of a CFE when a CFE is initially consolidated. It permits entities to make an accounting policy election to apply this same measurement approach after initial consolidation or to apply other GAAP to account for the consolidated CFE’s financial assets and financial liabilities. It also prohibits all entities from electing to use the fair value option in ASC 825, Financial Instruments, to measure either the financial assets or financial liabilities of a consolidated CFE that is within the scope of this issue. This guidance is effective for fiscal years beginning after December 15, 2015 and interim periods therein. Early adoption is permitted using a modified retrospective transition approach as described in the pronouncement. The Company has not yet adopted ASU 2014-13 and is currently evaluating the impact ASU 2014-13 is expected to have on its consolidated financial statements. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). ASU 2014-09 provides a comprehensive new revenue recognition model requiring a company to recognize revenue to depict the transfer of goods or services to a customer at an amount reflecting the consideration it expects to receive in exchange for those goods or services. Companies may use either a full retrospective or a modified retrospective approach. In July 2015, the FASB confirmed a deferral of the effective date by one year, with early adoption on the original effective date permitted. As deferred, ASU 2014-09 is effective for the first interim period within annual reporting periods beginning after December 15, 2017 with early adoption permitted. The Company has not yet adopted ASU 2014-09 and is currently evaluating the impact ASU 2014-09 is expected to have on its consolidated financial statements.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, these financial statements contain all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of the Company’s financial condition and results of operations. Operating results for the three and nine months ended September 30, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015. We have reclassified certain amounts in prior-period financial statements to conform to the current period's presentation.

The condensed consolidated financial statements include the accounts of the Company, its subsidiaries and sponsored investment products in which it has a controlling financial interest, referred to as consolidated sponsored investment products or consolidated investment product. The Company is generally considered to have a controlling financial interest when it owns a majority of the voting interest in an entity or otherwise has the power to govern the financial and operating policies of the subsidiary.
