These statements identify prospective information. Important factors could cause actual results to differ, possibly materially, from those indicated in these statements. Forward-looking statements are based on the Company’s beliefs, assumptions and expectations of its future performance, taking into account all information currently available to the Company. Such forward-looking statements are subject to risks and uncertainties and assumptions relating to the Company’s operations, financial results, financial condition, business prospects, growth strategy and liquidity, including, but not limited to, changes in the Company’s anticipated revenue and income, which are inherently volatile; changes in the value of the Company’s investments; the pace of the Company’s raising of new funds and liquidation of the Company’s old funds; changes in the Company’s operating or other expenses; the degree to which the Company encounters competition; and general economic and market conditions. The factors listed in the section captioned “Risk Factors” in the Company’s prospectus dated April 11, 2012, which was filed with the SEC on April 12, 2012 in accordance with Rule 424(b) of the Securities Act and is accessible on the SEC’s website at www.sec.gov, provide examples of risks, uncertainties and events that may cause the Company’s actual results to differ materially from the expectations described in its forward-looking statements.
