Acquisitions	Acquisitions Acquisitions are accounted for under ASC 805, Business Combinations. On September 23, 2016, we acquired a 100% ownership interest in Ramius Alternative Solutions LLC ("RASL"), a global alternative investment management business that, as of the acquisition date, had approximately $2.5 billion in AUM. RASL offers a range of customized alternative investment and advisory solutions to a global institutional client base. On the acquisition date, we made a cash payment of $20.5 million and recorded a contingent consideration payable of $11.9 million based on projected fee revenues over a five-year measurement period. The excess of the purchase price over the current fair value of identifiable net assets acquired resulted in the recognition of $21.9 million of goodwill. We recorded $10.0 million of definite-lived intangible assets relating to investment management contracts. On June 20, 2014, we acquired an 81.7% ownership interest in CPH Capital Fondsmaeglerselskab A/S (“CPH”), a Danish asset management firm that managed approximately $3 billion in global core equity assets for institutional investors, for a cash payment of $64.4 million and a contingent consideration payable of $9.4 million based on projected assets under management levels over a three-year measurement period. The excess of the purchase price over the fair value of identifiable assets acquired resulted in the recognition of $58.1 million of goodwill. We recorded $24.1 million of definite-lived intangible assets relating to separately-managed account relationships and $3.5 million of indefinite-lived intangible assets relating to an acquired fund’s investment contract. We also recorded redeemable non-controlling interests of $16.5 million relating to the fair value of the portion of CPH we did not own. During 2015 and 2016, we purchased additional shares of CPH, bringing our ownership interest to 90.4% as of December 31, 2016.
