However, there is no guarantee that we will be successful. Although the shares of certain products have been approved for trading on a secondary market, investors in the new products should not assume that the shares will ever obtain such an approval due to a variety of factors, including questions regulators, such as the SEC, FINRA, or other regulatory bodies may have regarding such products. As a result, shareholders of such products should be prepared to bear the risk of investment in the shares indefinitely.
