"Since Inception" is calculated to include performance from the Fund's predecessor limited partnership (Performance Inception Date: 1/1/2003). The 3 year, 5 year, 10 year and Since Inception returns represent average annual total returns. The average annual total returns of the Driehaus Micro Cap Growth Fund include the performance of one of the Fund's predecessor limited partnerships, which is calculated from January 1, 2003, before the Fund commenced operations and succeeded to the assets of its predecessors on November 18, 2013. The Fund's predecessors are the Driehaus Micro Cap Fund, L.P. (1996 inception) and the Driehaus Institutional Micro Cap Fund, L.P. (2011 inception). The performance of the Driehaus Micro Cap Fund, L.P., which was selected because it has the longer track record of the two predecessor partnerships, has been restated to reflect estimated expenses of the Fund. The predecessor limited partnerships were not registered under the Investment Company Act of 1940, as amended ("1940 Act") and thus were not subject to certain investment and operational restrictions that are imposed by the 1940 Act. If the predecessors had been registered under the 1940 Act, their performance may have been adversely affected. After-tax performance returns are not included for the Driehaus Micro Cap Fund, L.P. The predecessors were not regulated investment companies and therefore did not distribute current or accumulated earnings. Sources: Driehaus Capital Management LLC, Russell Investments, SS&C Inc.

The Limited Partnerships were managed by the same investment team with substantially the same investment objective, policies and philosophies as the Fund. The investment portfolios of the Limited Partnerships were identical and therefore had similar performance. The performance of the Predecessor Partnership is shown here because it has been in operation the longest.

If the Predecessor Partnership had been registered under the 1940 Act, its performance may have been adversely affected. Accordingly, future Fund performance may be different than the Predecessor Partnership’s past performance. After-tax performance returns are not included for the Predecessor Partnership. The Predecessor Partnership was not a regulated investment company under Subchapter M of the Internal Revenue Code of 1986, as amended, and therefore did not distribute current or accumulated earnings and profits and was not subject to the diversification and source of income requirements applicable to regulated investment companies.
