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.
