Finance, The Wall Street Journal, Barron's, Investors Business Daily, Newsweek,

performance may also be compared to the performance of other mutual funds
tracked by financial or business publications or periodicals. The Fund may also
quote evaluations mentioned in independent radio or television broadcasts and
may use charts and graphs to illustrate the past performance of various indices
such as those mentioned above and illustrations using hypothetical rates of
return to illustrate the effects of compounding and tax-deferral. Each Fund may
advertise examples of the effects of periodic investment plans, including the
principle of dollar cost averaging. In such a program, an investor invests a
fixed dollar amount in a fund at periodic intervals, thereby purchasing fewer
shares when prices are high and more shares when prices are low. While such a
strategy does not assure a profit or guard against a loss in a declining market,
the investor's average cost per share can be lower than if fixed numbers of
shares are purchased at the same intervals.
From time to time, each Fund may discuss or quote its current portfolio
manager as well as other investment personnel, including such persons' views on:
the economy; securities markets; portfolio securities and their issuers;
investment philosophies, strategies, techniques and criteria used in the
selection of securities to be purchased or sold for the Fund; the Fund's
portfolio holdings; the investment research and analysis process; the
formulation and evaluation of investment recommendations; and the assessment and
evaluation of credit, interest rate, market and economic risks and similar or
related matters.
The date of this Supplement is May 9, 1996.
