**Represents the Annual Fund Operating Expenses for the year ended December 31, 2008 as disclosed in the current prospectus dated April 30, 2009. It is important to understand that a decline in the Fund’s average net assets due to unprecedented market volatility or other factors could cause the Fund’s expense ratio for the current fiscal year to be higher than the expense information presented. Due to the expense limitation agreement described below, however, the Fund’s expense ratio would be limited to 2.00%. The Fund participates in a commission recapture program by directing certain portfolio trades to brokers who have agreed to rebate to the Fund a portion of the commissions generated. For the year ended December 31, 2008, these rebates were used to pay certain Fund expenses, which ultimately reduced the Fund's "Total Annual Fund Operating Expenses" to 1.75%. Driehaus Capital Management LLC ("the Adviser") has entered into a written agreement dated December 1, 2008 to cap the Fund’s annual operating expenses at 2.00% of average daily net assets until December 1, 2011. For a period of three years subsequent to the date of the agreement, the Adviser is entitled to reimbursement for previously waived fees and reimbursed expenses to the extent that the Fund’s expense ratio remains below the operating expense cap.

***Represents the Annual Fund Operating Expenses for the year ended December 31, 2008 as disclosed in the current prospectus dated April 30, 2009. It is important to understand that a decline in the Fund’s average net assets due to unprecedented market volatility or other factors could cause the Fund’s expense ratio for the current fiscal year to be higher than the expense information presented. The Fund pays Driehaus Capital Management LLC an annual management fee on a monthly basis as follows: 1.50% on the first $500 million of average daily net assets; 1.35% on the next $500 million; and 1.25% of average daily net assets in excess of $1 billion. The Fund participates in a commission recapture program by directing certain portfolio trades to brokers who have agreed to rebate to the Fund a portion of the commissions generated. For the year ended December 31, 2008, these rebates were used to pay certain Fund expenses, which ultimately reduced the Fund’s “Total Annual Fund Operating Expenses” to 1.64%.

Due to the expense limitation agreement described below, however, the Fund’s expense ratio would be limited to 2.00%. “Other Expenses” are estimated for the current fiscal year because the Fund commenced operations on May 1, 2008 and has not yet completed a full fiscal year. The Fund participates in a commission recapture program by directing certain portfolio trades to brokers who have agreed to rebate to the Fund a portion of the commissions generated. For the period ended December 31, 2008, these rebates were available to pay certain Fund expenses, although this had no impact on the Fund’s “Total Annual Fund Operating Expenses.” Driehaus Capital Management LLC ("the Adviser") has entered into a written agreement to cap the Fund’s annual operating expenses at 2.00% of average daily net assets until April 30, 2011. For a period of three years subsequent to the Fund’s commencement of operations on May 1, 2008, the Adviser is entitled to reimbursement for previously waived fees and reimbursed expenses to the extent that the Fund’s expense ratio remains below the operating expense cap.

******As disclosed in the current prospectus dated April 15, 2009, the Annual Fund Operating Expenses are estimated for the current fiscal year because the Fund did not commence operations until April 27, 2009. Driehaus Capital Management LLC ("the Adviser") has entered into a written agreement to cap the Fund’s operating expenses at 1.75% of average daily net assets until April 26, 2012. For a period of three years subsequent to the Fund’s commencement of operations, the Adviser is entitled to reimbursement for previously waived fees and reimbursed expenses to the extent that the Fund’s expense ratio remains below the expense cap.

*******As disclosed in the current prospectus dated May 6, 2009, “Other Expenses,” which include a shareholder services fee, are estimated for the current fiscal year because the Fund did not commence operations until June 1, 2009. The information in the table reflects the expenses of the Predecessor Fund for the fiscal year ended September 30, 2008, adjusted for the shareholder services fee. The Adviser has entered into a written agreement to cap the Fund’s ordinary operating expenses, excluding Dividends and Interest on Short Sales, at 1.00% of average daily net assets until May 31, 2010. For this same one year period, the Adviser is entitled to reimbursement for previously waived fees and reimbursed expenses to the extent that the Fund’s ordinary operating expenses, excluding Dividends and Interest on Short Sales, remain below the operating expense cap.

The Funds invest in foreign securities, including small and mid cap stocks, which may be subject to greater volatility than other investments. During certain periods, the Funds have benefited from unusually strong market conditions. At times, a significant portion of a Fund's return may be attributable to investments in initial public offerings (IPOs) or concentrations in certain strong performing sectors, such as technology. Returns from IPOs or sector concentrations may not be repeated or consistently achieved in the future. In addition, participating in IPOs and other investments during favorable market conditions may enhance the performance of a Fund with a smaller asset base, and the Fund may not experience similar performance results as its assets grow.

Stocks of medium-sized companies tend to be more volatile in price than those of larger companies and may have underperformed the stocks of small and large companies during some periods. In addition, investments in medium-sized companies may be more susceptible to particular economic events or competitive factors than are larger, more broadly diversified companies. Growth stocks may involve special risks and their prices may be more volatile than the overall market.

The Driehaus Active Income Fund (the "Fund"), in addition to investing in unrated and investment grade bonds, may also invest in junk bonds, which involve greater credit risk, including the risk of default. The prices of high yield bonds are more sensitive to changing economic conditions and can fall dramatically in response to negative news about the issuer or its industry, or the economy in general. The use of derivatives involves risks different from, and possibly greater than, the risks associated with investing directly in the underlying assets. Derivatives can be highly volatile, illiquid and difficult to value, and there is a risk that changes in the value of a derivative held by the Fund will not correlate with the Fund’s other investments. Further, the Fund may invest in derivatives for speculative purposes. Gains or losses from speculative positions in a derivative may be much greater than the derivative’s original cost and potential losses may be substantial. The Fund may make short sales. Short sales expose the Fund to the risk of loss. It is anticipated that the Fund will experience high rates of portfolio turnover, which may result in payment by the Fund of above-average transaction costs. This is a nondiversified fund; compared to other funds, the Fund may invest a greater percentage of assets in a particular issuer or a small number of issuers. As a consequence, the Fund may be subject to greater risks and larger losses than diversified funds.

Investments in overseas markets can pose more risks than U.S. investments, and share prices the Funds' are expected to be more volatile than that of a U.S.-only fund. In addition, the Funds' returns will fluctuate with changes in stock market conditions, currency values, interest rates, foreign government regulations, and economic and political conditions in countries in which the Funds invest. These risks are generally greater when investing in emerging markets. These and other risk considerations are discussed in the Funds' prospectus.
