Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions A prior owner of one of the Company’s Affiliates retained an interest in certain of the Affiliate’s private equity investment partnerships. The prior owner’s interest is presented in the Company’s Consolidated Balance Sheets as either a liability in Other liabilities or as Non-controlling interests, depending on the structure of the prior owner’s investments in the partnerships. The total liability was $75.0 million and $72.1 million at December 31, 2015 and September 30, 2016, respectively. The total non-controlling interest was $5.1 million and $3.3 million at December 31, 2015 and September 30, 2016, respectively. In certain cases, Affiliate management owners and Company officers may serve as trustees or directors of certain mutual funds from which the Affiliate earns advisory fee revenue. The Company has liabilities to related parties for contingent payment arrangements in connection with certain business combinations. The total amount payable was $10.2 million and $8.2 million as of December 31, 2015 and September 30, 2016, respectively, and was included in Other liabilities. In the first half of 2015, the Company made payments of $17.5 million associated with these liabilities. In 2016, no such payments have been made. For the nine months ended September 30, 2015, the Company adjusted its estimate of its contingent payment obligations and, accordingly, recorded a total gain attributable to the controlling interest of $44.7 million. For the nine months ended September 30, 2016, the Company adjusted its estimates of its contingent payment obligations and, accordingly, recorded gains attributable to the controlling interest of $2.8 million, all of which occurred in the first three months of the period. These amounts are included in Imputed interest expense and contingent payment arrangements in the Consolidated Statements of Income.
