__________________________ (1)The Company accounts for its interests in private equity funds under the equity method of accounting and, therefore, uses NAV as a practical expedient, one quarter in arrears (adjusted for current period calls and distributions) to determine the fair value. These funds primarily invest in a broad range of third-party funds and direct investments. Distributions will be received as the underlying assets are liquidated over the life of the funds, which is generally up to 15 years. (2)These are multi-disciplinary funds that invest across various asset classes and strategies, including equity, credit, and real estate. Investments are generally redeemable on a daily, monthly or quarterly basis. (3)Fair value attributable to the controlling interest was $137.6 million and $164.4 million as of December 31, 2019 and 2020, respectively.
