The following information supplements disclosure in the Fund's prospectus and
remains in effect until further notice:

Due to recent market events, regulatory authorities in various countries have
enacted temporary rules prohibiting the short-selling of certain stocks. The
length of the bans and the types of securities included in the bans vary from
country to country. While most prohibitions focus on the short-selling of
financial stocks, some countries may have more extensive bans.

As described in the prospectus, the Fund utilizes a long/short investment
strategy in which a portion of the Fund's assets are short positions. While the
prohibitions remain in effect, the Fund will be restricted from engaging in
short sales of certain securities, primarily in the financial sector.
