These costs, which are not reflected in annual fund operating expenses or in the example, affect the Funds performance.

Because the Fund may invest in securities of a smaller number of issuers, it may be more exposed to the risks associated with and developments affecting an individual issuer than a fund that invests more widely.

For the most part, these securities will be common stock. Many of the companies in which the Fund invests are located in markets generally considered to be emerging markets. The Fund may also invest in convertible securities. The Fund invests in companies it believes are undervalued relative to the market. Current income from dividends and interest will not be an important factor in selecting the securities in which the Fund will invest. Risk is inherent in all investing. The value of your investment in Pacific Fund, as well as the amount of return you receive on your investment, may fluctuate significantly from day to day and over time. You may lose part or all of your investment in the Fund or your investment may not perform as well as other similar investments. The following is a summary description of certain risks of investing in the Fund.  <table style="BORDER-COLLAPSE:COLLAPSE" border="0" cellpadding="0" cellspacing="0" width="100%"> <tr> <td width="1%" valign="top" align="left">n</td> <td width="1%" valign="top"> </td> <td align="left" valign="top"> Convertible Securities Risk  The market value of a convertible security performs like that of a regular debt security; that is, if market interest rates rise, the value of a convertible security usually falls. In addition, convertible securities are subject to the risk that the issuer will not be able to pay interest or dividends when due, and their market value may change based on changes in the issuers credit rating or the markets perception of the issuers creditworthiness. Since it derives a portion of its value from the common stock into which it may be converted, a convertible security is also subject to the same types of market and issuer risk as apply to the underlying common stock. </td></tr></table> <table style="BORDER-COLLAPSE:COLLAPSE" border="0" cellpadding="0" cellspacing="0" width="100%"> <tr> <td width="1%" valign="top" align="left">n</td> <td width="1%" valign="top"> </td> <td align="left" valign="top"> Emerging Markets Risk  Emerging markets are riskier than more developed markets because they tend to develop unevenly and may never fully develop. Investments in emerging markets may be considered speculative. Emerging markets are more likely to experience hyperinflation and currency devaluations, which adversely affect returns to U.S. investors. In addition, many emerging securities markets have far lower trading volumes and less liquidity than developed markets. </td></tr></table> <table style="BORDER-COLLAPSE:COLLAPSE" border="0" cellpadding="0" cellspacing="0" width="100%"> <tr> <td width="1%" valign="top" align="left">n</td> <td width="1%" valign="top"> </td> <td align="left" valign="top"> Equity Securities Risk  Stock markets are volatile.
