[1] | The fair value of the intangible assets is comprised of investment management contracts with a fair value of $28.0 million, client relationships with a fair value of $20.5 million and a trademark with a fair value of $5.5 million as of the acquisition date. The fair value of the investment management contracts was determined based on the multi-period excess earnings method (a Level 3 input), has a useful life of approximately 4 years. The fair value of the client relationships was determined based on the multi-period excess earnings method (a Level 3 input) and has a useful life of approximately 4-10 years. The fair value of the trademark was determined based on the relief-from-royalty method (a Level 3 input) and has a useful life of 9 years. The useful lives are based on the individual contractual terms and the period over which the majority of cashflows would be realized. The definite lived intangibles are amortized on a straight-line basis over the useful life and have a weighted-average useful life of approximately 6 years.
[2] | The fair value of the noncontrolling interest was determined based on an extrapolation of consideration method.
