The Funds do not permit market timing. Do not invest in the Funds if you are a market-timer. As money is shifted in and out of a Fund, the Fund incurs expenses for buying and selling securities. These costs are borne by all Fund shareholders, including long-term investors who do not generate such costs. Therefore, the Funds have adopted the following policies to discourage short-term trading:

  • The Funds (excluding the Active Income Fund, Event Driven Fund and Multi-Asset Growth Economies Fund) will deduct 2% from the redemption amount if you sell shares within 60 days of purchase.
  • The Funds reserve the right to reject any purchase order -- including exchanges from other Driehaus Mutual Funds -- that it regards as disruptive to the efficient management of the Funds.
  • The Funds reserve the right to limit the number of times that you can exchange into and out of a Fund. 
  • The Funds reserve the right to stop offering shares at any time.

Shareholder Net Asset Value Information
Each Fund's net asset value is determined as of the regular close of the New York Stock Exchange ("NYSE") (normally 3 p.m., Central time) on each day the NYSE is open for trading. Purchases and redemptions are made at a Fund's net asset value per share next calculated after receipt of your purchase or redemption order in good form. Net asset value per share is determined by dividing the difference between the values of a Fund's assets and its liabilities by the number of its shares outstanding. Because foreign securities markets may operate on days that are not business days in the United States, the value of a Fund's holdings may change on days when you will not be able to purchase or redeem the Funds' shares.
