Past performance is no guarantee of future results. Any historical returns, expected returns, or probability projections may not reflect actual future performance. All securities involve risk and may result in significant losses.

Alternative investments in private placements are highly illiquid, speculative, and involve a high degree of risk. Past performance is not indicative of future results. Investors may not get back their money originally invested and those who cannot afford to lose their entire investment should not invest. Prior to investing, carefully consider the respective fund documentation for details about potential risks, charges, and expenses. The value of an investment may go down as well as up. An investment in a private equity ("PE") fund or investment vehicle as Openstone SA, registered under number 98307779300013 and located at 61 rue de Lyon, 75012 Paris, is not the same as a deposit with a banking institution. Investors receive illiquid and/or restricted membership interests that may be subject to holding period requirements and/or liquidity concerns. Investors who cannot hold an investment for the long term (at least 10 years) should not invest. In the most sensible investment strategy for PE investing, PE should only be part of your overall investment portfolio.
