deleted in its entirety and replaced with the following:&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 12pt 0 0"&gt;The Fund&#x2019;s portfolio will
generally consist of between 25 and 50 securities. The Fund may also invest in securities offered in an initial public offering ("IPO")
or in companies that have recently completed an IPO. The Fund may invest in foreign securities directly or indirectly via depositary receipts
(e.g., American Depositary Receipts (ADRs) and Global Depositary Receipts (GDRs)).&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 12pt 0 0"&gt;&lt;b&gt;IPO Risk&lt;/b&gt;. The Fund may invest in securities
offered in an IPO or in companies that have recently completed an IPO. The market value of IPO shares can have significant volatility
due to factors such as the absence of a prior public market, unseasoned trading, a small number of shares available for trading and limited
information about the issuer. The purchase of IPO shares may involve high transaction costs, and the Fund may lose money on an investment
in such securities.&lt;/p&gt;
