Description of Business and Significant Accounting Policies
Basis of Presentation	Basis of Presentation We have prepared the accompanying unaudited consolidated financial statements pursuant to the rules and regulations of the SEC. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations, although we believe that the disclosures are adequate to enable a reasonable understanding of the information presented. The information in this Quarterly Report on Form 10-Q should be read in conjunction with Part I, Item 2 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our audited financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2015 (the “2015 Form 10-K”). Certain amounts in the prior years’ financial statements have been reclassified for consistent presentation. The accompanying unaudited consolidated financial statements are prepared consistent with the accounting policies described in Note 1 to the consolidated financial statements included in our 2015 Form 10-K except as noted below. In our opinion, the accompanying unaudited consolidated financial statements reflect all adjustments (consisting of only a normal and recurring nature) necessary to present fairly our financial position at September 30, 2016, the results of operations and cash flows for the nine months ended September 30, 2016 and 2015 in conformity with accounting principles generally accepted in the United States.
Investment Securities and Investments in Sponsored Funds	Investments Securities and Investments in Sponsored Funds Sponsored funds, which include the Funds, the IGI Funds and privately offered funds structured in the form of limited liability companies, are investments we have made for general corporate investment purposes and to provide seed capital for new investment products. The Company’s initial investment in a new investment product typically represents 100% ownership in that product. Sponsored funds are initially consolidated and are accounted for as trading securities. The Company has classified its investments in certain sponsored funds as either equity method investments (when the Company owns between 20% and 50% of the fund) or as available for sale investments (when the Company owns less than 20% of the fund) as described in Note 4. Investments held by our broker-dealer entities or certain investments that are anticipated to be purchased and sold on a more frequent basis are classified as trading.

Disclosure of accounting policy for investments in financial assets, including marketable securities (debt and equity securities with readily determinable fair values), investments accounted for under the equity method and cost method, securities borrowed and loaned, and repurchase and resale agreements. For marketable securities, the disclosure may include the entity's accounting treatment for transfers between investment categories and how the fair values for such securities are determined. Also, for all investments, an entity may describe its policy for assessing, recognizing and measuring impairment of the investment.
