evaluates the financial conditions and competitiveness of individual companies
worldwide. It uses a blend of both traditional fundamental research, calling on
the expertise of many external analysts in different countries throughout the
world, and systematic disciplines to uncover signs of "change at the margin"
- --positive business developments which are not yet fully reflected in a
company's stock price. It gathers financial data on 20,000 companies in over 50
countries, and searches for successful, growing companies managing change
advantageously and poised to exceed growth expectations.
 
PRINCIPAL INVESTMENTS
 
    The Fund invests in the larger capitalized companies in each country.
Generally, this means issuers in each country whose market capitalizations are
in the top 75% of publicly traded companies as measured by capitalizations in
that country. Under normal conditions, the Fund invests at least 65% of its
total assets in securities of issuers located in at least three countries
outside the U.S. The Fund may invest up to 35% of its total assets in U.S.
issuers.
 
    Under normal conditions, the Fund invests at least 75% of its total assets
in common and preferred stocks, warrants and convertible securities. It invests
the remainder primarily in investment grade debt securities of any maturity of
foreign companies and foreign governments and their agencies and
instrumentalities. The Fund may also use options and futures contracts as
hedging techniques.
 
PORTFOLIO MANAGEMENT
 
    The Investment Adviser emphasizes a team approach to portfolio management to
maximize its overall effectiveness. For a complete listing of the portfolio
team, see "Portfolio Teams" on page 38.
 
RISK FACTORS
 
    The value of the Fund's investments varies from day to day in response to
the activities of individual companies and general market and economic
conditions. As with any international fund, performance also depends upon
changing values in foreign currencies, different political and regulatory
environments, and other overall economic factors in the countries where the Fund
invests. For further explanation, see "Risk Factors and Special Considerations"
starting on page 41.
 
INVESTOR EXPENSES--CLASS A, B AND C SHARES

(1) Shareholders who buy $1 million in shares without paying a sales charge may
    be charged a contingent deferred sales charge of 1% on redemptions made
    within one year of purchase. See "Contingent Deferred Sales Charge" in this
    prospectus.
   
(2) The Investment Adviser has agreed to waive or defer its management fees and
    to absorb other operating expenses payable by the Fund Class. For Portfolios
    A, B & C, Total operating expenses would have been 4,580%, 16,000% and 
    25.55% respectively and Other expenses would have been 4,579%, 15,998% and
    23.80% respectively, absent the deferral. See "Investment Adviser 
    Compensation."
    
    Because of the 12b-1 fee, long-term shareholders may indirectly pay more
than the equivalent of the maximum permitted front-end sales charge.

WORLDWIDE GROWTH FUND
 
INVESTMENT OBJECTIVE
 
    Maximum long-term capital appreciation.
 
INVESTMENT STRATEGY
 
    The Fund's Investment Adviser focuses on a "bottom-up" analysis that
evaluates the financial conditions and competitiveness of individual companies
worldwide. It uses a blend of both traditional fundamental research, calling on
the expertise of many external analysts in different countries throughout the
world, and systematic disciplines to uncover signs of "change at the margin"
- --positive business developments which are not yet fully reflected in a
company's stock price. It gathers financial data on 20,000 companies in over 50
countries, and searches for successful, growing companies managing change
advantageously and poised to exceed growth expectations.
 
PRINCIPAL INVESTMENTS
 
    Under normal conditions, the Fund invests at least 65% of its total assets
in securities of issuers located in at least three different countries, one of
which may be the U.S. The Fund may invest up to 50% of its total assets in U.S.
issuers.
 
    Under normal conditions the Fund invests at least 75% of its total assets in
common and preferred stocks, warrants and convertible securities. It invests the
remainder in investment grade debt securities of any maturity issued by foreign
companies and foreign governments and their agencies and instrumentalities. The
Fund may also use options and futures contracts as hedging techniques.
 
PORTFOLIO MANAGEMENT
 
    The Investment Adviser emphasizes a team approach to portfolio management to
maximize its overall effectiveness. For a complete list of the portfolio team,
see "Portfolio Teams" on page 38.
 
RISK FACTORS
 
    The value of the Fund's investments varies from day to day in response to
the activities of individual companies, and general market and economic
conditions. The securities of small, less well-known companies may be more
volatile than those of larger companies. As with any international fund,
performance also depends upon changing currency values, different political and
regulatory environments, and other overall economic factors in the countries
where the Fund invests. The risks are magnified in countries with emerging
markets, since these countries may have unstable governments and less
established markets. For a further explanation, see "Risk Factors and Special
Considerations" starting on page 41.
 
INVESTOR EXPENSES--CLASS A, B AND C SHARES
 
    Investors pay various expenses, either directly or indirectly. Actual
expenses may be more or less than those shown.

(2) The Investment Adviser has agreed to waive or defer its management fees and
    to absorb other operating expenses payable by the Fund. For Class A, B & C,
    Total operating expenses would have been 2.17%, 4.81% and 2.61% respectively
    and Other expenses would have been .92%, 3.06% and .86% respectively, absent
    the deferral. See "Investment Adviser Compensation."

INTERNATIONAL SMALL CAP GROWTH FUND
 
INVESTMENT OBJECTIVE
 
    Maximum long-term capital appreciation.
 
INVESTMENT STRATEGY
 
    The Fund's Investment Adviser focuses on a "bottom-up" analysis that
evaluates the financial conditions and competitiveness of individual companies
worldwide. It uses a blend of both traditional fundamental research, calling on
the expertise of many external analysts in different countries throughout the
world, and systematic disciplines to uncover signs of "change at the margin"
- --positive business developments which are not yet fully reflected in a
company's stock price. It gathers financial data on 20,000 companies in over 50
countries, and searches for successful, growing companies managing change
advantageously and poised to exceed growth expectations.
 
    The Fund emphasizes companies in the bottom 75% of publicly traded companies
as measured by market capitalizations in each country ("small cap securities").
The Fund may have less U.S. exposure (up to 35% of its total assets in U.S.
issuers) than the Worldwide Growth Fund.
 
PRINCIPAL INVESTMENTS
 
    Under normal conditions, the Fund invests 65% of its total assets in small
cap securities of issuers located in at least three different countries outside
the U.S. Under normal conditions, the Fund invests at least 75% of its total
assets in common and preferred stock, warrants and convertible securities. It
invests the remainder primarily in investment grade debt securities of any
maturity issued by foreign companies and foreign governments and their agencies
and instrumentalities. The Fund may also use options and futures contracts as
hedging techniques.
 
PORTFOLIO MANAGEMENT
 
    The Investment Adviser emphasizes a team approach to portfolio management to
maximize its overall effectiveness. For a complete list of the portfolio team,
see "Portfolio Teams" on page 38.
 
RISK FACTORS
 
    The value of the Fund's investments varies from day to day in response to
the activities of individual companies, and general market and economic
conditions. As with any international fund, the Fund's performance also depends
upon changing currency values, different political and regulatory environments,
and other overall economic factors in the countries where the Fund invests. In
addition to the risks posed by foreign investing, the securities of smaller,
less well known companies may be more volatile than larger companies and may
trade less frequently. The information regarding these smaller companies may
also be less available, incomplete or inaccurate. Accordingly, the securities of
the companies in which the Fund invests may be more volatile and speculative
than those of larger companies. The risks are magnified in countries with
emerging markets since these countries may have unstable governments and less
established markets. For further explanation, see "Risk Factors and Special
Considerations" starting on page 41.

INVESTOR EXPENSES--CLASS A, B AND C SHARES
 
Investors pay various expenses, either directly or indirectly. Actual
expenses may be more or less than those shown.

</TABLE>
- ------------------------
(1) Shareholders who buy $1 million in shares without paying a sales charge may
    be charged a contingent deferred sales charge of 1% on redemptions made
    within one year of purchase. See "Contingent Deferred Sales Charge" in this
    prospectus.
 
(2) The Investment Adviser has agreed to waive or defer its management fees and
    to absorb other operating expenses payable by the Fund. For Class A, B & C,
    Total operating expenses would have been 3.76%, 4.89% and 3.95% respectively
    and Other expenses would have been 2.51%, 3.14% and 2.20% respectively,
    absent the deferral. See "Investment Adviser Compensation."
 
    Because of the 12b-1 fee, long-term shareholders may indirectly pay more 
than the equivalent of the maximum permitted front-end sales charge.

EMERGING COUNTRIES FUND
 
INVESTMENT OBJECTIVE

    Maximum long-term capital appreciation.

INVESTMENT STRATEGY

    The Fund invests primarily in equity securities of issuers located in
countries with emerging securities market-- that is, countries with securities
markets which are, in the opinion of the Investment Adviser, emerging as
investment markets but have yet to reach a level of maturity associated with
developed foreign stock markets, especially in terms of participation by foreign
investors. The Investment Adviser seeks issuers in the early stages of
development, growth companies, cyclical companies, or companies believed to be
undergoing a basic change in operations. The Investment Adviser currently
selects portfolio securities from an investment universe of approximately 6,000
foreign issuers in over 20 emerging markets.
 
PRINCIPAL INVESTMENTS
 
    Under normal conditions, the Fund invests at least 65% of its total assets
in securities of issuers located in at least three different countries. These
countries include but are not limited to: Argentina, Brazil, Chile, China,
Colombia, the Czech Republic, Greece, Hungary, India, Indonesia, Israel, Jordan,
Malaysia, South Africa, South Korea, Taiwan, Thailand, Italy and Venezuela.
 
    Under normal market conditions, the Fund invests at least 75% of its total
assets in corporate stock (common and preferred), warrants and convertible
securities. It invests the remainder primarily in investment grade bonds of
foreign companies and foreign governments and their agencies and
instrumentalities. The Fund may also use options and futures contracts as
hedging techniques.
 
PORTFOLIO MANAGEMENT
 
    The Investment Adviser emphasizes a team approach to portfolio management to
maximize its overall effectiveness. For a complete list of the portfolio team,
see "Portfolio Teams" on page 38.
 
RISK FACTORS
 
    The value of the Fund's investments varies from day to day in response to
the activities of individual companies and general market and economic
conditions. As with any fund investing in foreign securities, the Fund's
performance also depends upon changing currency values, different political and
regulatory environments, and other overall economic factors in the countries
where the Fund invests. Emerging countries markets may present greater
opportunity for gain, but also involve greater risk than more developed markets.
These countries tend to have less stable governments and less established
markets. The markets tend to be less liquid and more volatile, and offer less
regulatory protection for investors. The economies of emerging countries may be
predominantly based on only a few industries or dependent on revenue from
particular commodities, international aid or other assistance. For further
explanation, see "Risk Factors and Special Considerations" starting on page 41.

INVESTOR EXPENSES--CLASS A, B AND C SHARES

Investors pay various expenses, either directly or indirectly. Actual
expenses may be more or less than those shown.

- ------------------------
 
(1) Shareholders who buy $1 million in shares without paying a sales charge may
    be charged a contingent deferred sales charge of 1% on redemptions made
    within one year of purchase. See "Contingent Deferred Sales Charge" in this
    prospectus.
 
(2) The Investment Adviser has agreed to waive or defer its management fees and
    to absorb other operating expenses payable by the Fund. For Class A, B & C,
    Total operating expenses would have been 3.08%, 3.66% and 3.12% respectively
    and Other expenses would have been 1.58%, 1.66% and 1.12% respectively,
    absent the deferral. See "Investment Adviser Compensation."

Because of the 12b-1 fee, long-term shareholders may indirectly pay more than 
the equivalent of the maximum permitted front-end sales charge.

LARGE CAP GROWTH FUND
 
INVESTMENT OBJECTIVE
 
Maximum long-term capital appreciation.
 
INVESTMENT STRATEGY
 
    The Fund's Investment Adviser focuses on a "bottom-up" analysis that 
evaluates the financial condition and competitiveness of individual 
companies. It uses a blend of both traditional fundamental research and 
computer intensive systematic disciplines to uncover signs of "change at the 
margin" -- positive business developments which are not yet fully reflected 
in a company's stock price. It searches for successful, growing companies 
that are managing change advantageously and poised to exceed growth 
expectations.
 
    The Fund emphasizes equity securities of U.S. companies with market
capitalizations generally above $3 billion and whose earnings and stock prices
are expected to grow faster than the S&P 500 ("large cap securities").
 
PRINCIPAL INVESTMENTS
 
    Under normal conditions, the Fund invests at least 65% of its total assets
in large cap securities, including common and preferred stocks, warrants, and
convertible securities of U.S. companies. It invests the remainder of its assets
primarily in investment grade corporate debt securities of any maturity, U.S.
Government securities, and equity securities of foreign issuers. The Fund may
also use options and futures contracts as hedging techniques.
 
PORTFOLIO MANAGEMENT
 
    The Investment Adviser emphasizes a team approach to portfolio management to
maximize its overall effectiveness. For a complete list of the portfolio team,
see "Portfolio Teams" on page 37.
 
RISK FACTORS
 
    As with any growth fund, the value of your investment will fluctuate from
day to day with movements in the stock markets as well as in response to the
activities of individual companies. To the extent the Fund is overweighted in
certain market sectors compared to the S&P 500, the Fund may be more volatile
than the S&P 500. Additionally, to the extent the Fund invests in foreign
issuers, the risks and volatility are magnified since the performance of foreign
stocks also depends on changes in foreign currency values, different regulatory
and political environments, and overall political and economic conditions in
countries where the Fund invests. For further explanation, see "Risk Factors and
Special Considerations" starting on page 41.

    be charged a contingent deferred sales charge of 1% on redemptions made
    within one year of purchase. See "Contingent Deferred Sales Charge" in this
    prospectus.
 
(2) The Investment Adviser has agreed to waive or defer its management fees and
    to absorb other operating expenses payable by the Fund. For Class A, B & C,
    Total operating expenses would have been 2.31%, 2.96% and 2.96% respectively
    and Other expenses would have been 1.31%, 1.46% and 1.46% respectively,
    absent the deferral. See "Investment Adviser Compensation."
 
Because of the 12b-1 fee, long-term shareholders may indirectly pay more than
the equivalent of the maximum permitted front-end sales charge.

CORE GROWTH FUND

INVESTMENT OBJECTIVE

    Maximum long-term capital appreciation.

INVESTMENT STRATEGY

    The Fund's Investment Adviser focuses on a "bottom-up" analysis that 
evaluates the financial condition and competitiveness of individual 
companies. It uses a blend of both traditional fundamental research and 
computer intensive systematic disciplines to uncover what it calls "change at 
the margin" --positive business developments which are not yet fully 
reflected in the company's stock price. It searches for successful, growing 
companies that are managing change advantageously and poised to exceed growth 
expectations.
 
    The Fund emphasizes companies with market capitalizations above $500 
million.
 
PRINCIPAL INVESTMENTS
 
    Under normal conditions, the Fund invests at least 75% of its total 
assets in common stocks. It invests the remainder of its assets primarily in 
preferred and convertible securities, investment grade debt securities of any 
maturity, and securities issued by the U.S. Government and its agencies and 
instrumentalities. The Fund may invest up to 20% of its total assets in 
foreign securities. The Fund may also use options and futures contracts as 
hedging techniques.
 
PORTFOLIO MANAGEMENT
 
    The Investment Adviser emphasizes a team approach to portfolio management to
maximize its overall effectiveness. For a complete list of the portfolio team,
see "Portfolio Teams" on page 37.
 
RISK FACTORS
 
    As with any growth fund, the value of your investment will fluctuate from
day to day with movements in the stock markets. The companies in which the Fund
invests may be more subject to volatile market movements than securities of
larger, more established companies. To the extent the Fund invests in foreign
securities, the risks and volatility are magnified since the performance of
foreign stocks also depends upon changes in foreign currency values, different
political and regulatory environments, and the overall political and economic
conditions in countries where the Fund invests. For further explanation, see
"Risk Factors and Special Considerations" starting on page 41.

VALUE FUND
 
INVESTMENT OBJECTIVE
 
    Maximum long-term capital appreciation.
 
INVESTMENT STRATEGY
 
    The Fund's Investment Adviser focuses on a "bottom-up" analysis that
evaluates the financial condition and competitiveness of individual companies.
It uses a blend of traditional fundamental research and computer intensive
systematic disciplines to uncover signs of "change at the margin" -- positive
business developments which are not yet fully reflected in a company's stock
price. It searches for successful, growing companies that are managing change
advantageously and poised to exceed growth expectations.
 
    The Fund emphasizes companies with market capitalizations generally above $5
billion.
 
PRINCIPAL INVESTMENTS
 
    Under normal conditions, the Fund invests at least 80% of its total assets
in equity securities. It invests the remainder primarily in preferred and
convertible securities, investment grade debt securities of any maturity, and
securities issued by the U.S. Government and its agencies and instrumentalities.
The Fund may also use options and futures contracts as hedging techniques.
 
    The Fund's portfolio is designed to have risk, capitalization and industry
characteristics similar to those of the S&P 500 index.
 
PORTFOLIO MANAGEMENT
 
    The Investment Adviser emphasizes a team approach to portfolio management to
maximize its overall effectiveness. For a complete list of the portfolio team,
see "Portfolio Teams" on page 37.
 
RISK FACTORS
 
    As with any equity fund, the value of your investment will fluctuate from
day to day with movements in the stock markets. To the extent the Fund invests
in foreign securities, the risks and volatility are magnified since the
performance of foreign stocks depends upon changes in foreign currency values,
different political and regulatory environments, and the overall political and
economic conditions in countries where the Fund invests. For further
explanation, see "Risk Factors and Special Considerations" starting on page 41.


INVESTOR EXPENSES--CLASS A, B AND C SHARES
 
    Investors pay various expenses, either directly or indirectly. Actual
expenses may be more or less than those shown.

(1) Shareholders who buy $1 million in shares without paying a sales charge may
    be charged a contingent deferred sales charge of 1% on redemptions made
    within one year of purchase. See "Contingent Deferred Sales Charge" in this
    prospectus.
 
(2) The Investment Adviser has agreed to waive or defer its management fees and
    to absorb other operating expenses payable by the Fund. For Class A, B & C,
    Total operating expenses are expected to be 2.25%, 2.85% and 2.85%
    respectively, and Other expenses are expected to be 1.50%, 2.10% and 2.10%
    respectively, absent the deferral. See "Investment Adviser Compensation."

    Because of the 12b-1 fee, long-term shareholders may indirectly pay more
than the equivalent of the maximum permitted front-end sales charge.

EMERGING GROWTH FUND
 
INVESTMENT OBJECTIVE
 
    Maximum long-term capital appreciation.
 
INVESTMENT STRATEGY
 
    The Fund's Investment Adviser focuses on a "bottom-up" analysis that
evaluates the financial condition and competitiveness of individual companies.
It uses a blend of both traditional fundamental research and computer intensive
systematic disciplines to uncover what it calls "change at the margin" --
positive business developments which are not yet fully reflected in the
company's stock price. It searches for successful, growing companies that are
managing change advantageously and poised to exceed growth expectations.
 
    The Fund emphasizes companies with market capitalizations below $500 million
at the time of purchase.
 
PRINCIPAL INVESTMENTS
 
    Under normal conditions, the Fund invests at least 75% of its total assets
in common stocks. It invests the remainder primarily in preferred and
convertible securities, investment grade debt securities of any maturity, and
securities issued by the U.S. Government and its agencies and instrumentalities.
The Fund may invest up to 20% of its total assets in foreign securities. The
Fund may also use options and futures contracts as hedging techniques.
 
PORTFOLIO MANAGEMENT
 
    The Investment Adviser emphasizes a team approach to portfolio management to
maximize its overall effectiveness. For a complete list of the portfolio team,
see "Portfolio Teams" on page 37.
 
RISK FACTORS
 
    As with any growth fund, the value of your investment will fluctuate from
day to day with movements in the stock markets. Although small-cap stocks have a
history of long-term growth, they tend to be more volatile and speculative than
stocks of larger, more established companies. To the extent the Fund invests in
foreign issuers, the investment risks and volatility are magnified since the
performance of foreign stocks depends on changes in foreign currency values,
different political and regulatory environments, and the overall political and
economic conditions in the foreign countries where the Fund invests. For further
explanation, see "Risk Factors and Special Considerations" starting on page 41.

(1) Shareholders who buy $1 million in shares without paying a sales charge may
    be charged a contingent deferred sales charge of 1% on redemptions made
    within one year of purchase. See "Contingent Deferred Sales Charge" in this
    prospectus.
 
(2) The Investment Adviser has agreed to waive or defer its management fees and
    to absorb other operating expenses payable by the Fund. For Class B Total
    operating expenses would have been 2.73%, and Other expenses would have been
    .98%, absent the deferral. See "Investment Adviser Compensation."
 
    Because of the 12b-1 fee, long-term shareholders may indirectly pay more
than the equivalent of the maximum permitted front-end sales charge.

INCOME & GROWTH FUND
 
INVESTMENT OBJECTIVE
 
    Maximum total return, consisting of long-term capital appreciation and
current income.
 
INVESTMENT STRATEGY
 
    THE FUND INVESTS PRIMARILY IN CONVERTIBLE SECURITIES.  The Investment
Adviser evaluates each security's investment characteristics as a fixed income
instrument as well as its potential for capital appreciation. In evaluating
convertibles, the Investment Adviser searches for what it calls "change at the
margin" -- positive business developments which are not yet fully reflected in
the company's stock price. It searches for successful growing companies that are
managing change advantageously and poised to exceed growth expectations.
 
    The Fund seeks to capture approximately 70-80% of the upside performance of
the underlying equities with 50% or less of the downside exposure.
 
PRINCIPAL INVESTMENTS
 
    Under normal conditions, the Fund invests at least 65% of its total assets
in convertible securities. It invests the remainder primarily in common and
preferred stocks, debt securities of any maturity, and securities issued by the
U.S. Government and its agencies and instrumentalities. The Fund may also use
options and futures contracts as hedging techniques.
 
    At all times, the Fund invests a minimum of 25% of its total assets in
common and preferred stocks, and 25% in other income producing convertible and
debt securities. The Fund may also invest up to 35% of its net assets in debt
securities rated below investment grade by a nationally recognized statistical
rating agency, or of comparable quality if unrated.
 
    The Fund emphasizes companies with market capitalizations above $500
million.
 
PORTFOLIO MANAGEMENT
 
    The Investment Adviser emphasizes a team approach to portfolio management to
maximize its overall effectiveness. For a complete list of the portfolio team,
see "Portfolio Teams" on page 37.
 
RISK FACTORS
 
    Convertible securities have the investment characteristics of both equity
and debt securities. Accordingly, the value of your investment will fluctuate
with movements in the stock and bond markets. The companies in which the Fund
invests may be subject to more volatile market movements than securities of
larger, more established companies. The value of the Fund's debt securities will
change as interest rates fluctuate: if rates go up, the value of debt securities
goes down; if rates go down, the value of debt securities goes up. In addition,
the lower rated convertible securities in which the Fund may invest are
considered predominately speculative and are subject to greater volatility and
risk of loss than investment grade securities, particularly in deteriorating
economic periods. For further explanation, see "Risk Factors and Special
Considerations" starting on page 41.
 
INVESTOR EXPENSES--CLASS A, B AND C SHARES
 
    Investors pay various expenses, either directly or indirectly. Actual
expenses may be more or less than those shown.

(1) Shareholders who buy $1 million in shares without paying a sales charge may
    be charged a contingent deferred sales charge of 1% on redemptions made
    within one year of purchase. See "Contingent Deferred Sales Charge" in this
    prospectus.
 
(2) The Investment Adviser has agreed to waive or defer its management fees and
    to absorb other operating expenses payable by the Fund. For Class A, B & C,
    Total operating expenses would have been 1.75%, 3.19% and 2.29%,
    respectively, and Other expenses would have been .75%, 1.69% and .79%
    respectively, absent the deferral. See "Investment Adviser Compensation."
 
    Because of the 12b-1 fee, long-term shareholders may indirectly pay more
than the equivalent of the maximum permitted front-end sales charge.

BALANCED GROWTH FUND
 
INVESTMENT OBJECTIVE
 
    A balance of long-term capital appreciation and current income.
 
INVESTMENT STRATEGY
 
    The Fund's Investment Adviser actively manages a blended portfolio of equity
and fixed income securities with an emphasis on the overall total return. For
the equity portion, the Investment Adviser focuses on a "bottom-up" analysis
that evaluates the financial condition and competitiveness of individual
companies. It primarily uses computer intensive systematic disciplines to
uncover "change at the margin" -- positive business developments that are not
yet fully reflected in a company's stock price. The fixed income portion is
actively managed to take advantage of current interest rates and bond market
trends by varying the structure, duration and allocation of fixed income
investments from various business sectors.
 
PRINCIPAL INVESTMENTS
 
    Under normal conditions, the Fund allocates about 60% of its total assets
(but no more than 70% and no less than 50%) to equity securities, with an
emphasis on companies with market capitalizations in excess of $500 million, and
about 40% of its total assets to debt securities of any maturity issued by
corporations and the U.S.
 
    Government and its agencies and instrumentalities. A portion of the Fund's
net assets (less than 35%) may be invested in debt securities rated below
investment grade by a nationally recognized statistical rating agency, or of
comparable quality if unrated. The Fund may invest up to 20% of its total assets
in securities of foreign issuers. The Fund may also use options as a hedging
technique.
 
PORTFOLIO MANAGEMENT
 
    The Investment Adviser emphasizes a team approach to portfolio management to
maximize its overall effectiveness. For a complete list of the portfolio team,
see "Portfolio Teams" on page 37.
 
RISK FACTORS
 
    As with any fund that invests in common stocks and debt obligations, the
value of your investment will fluctuate with movements in the stock and bond
markets. Equity securities in which the Fund invests may be more volatile than
securities of larger, more established companies. The value of the Fund's debt
securities will change as interest rates fluctuate: if rates go up, the value of
debt securities goes down; if rates go down, the value of debt securities goes
up. Lower rated securities in which the Fund invests are considered speculative
and are subject to greater volatility and risk of loss than investment grade
securities, particularly in deteriorating economic periods. For further
explanation, see "Risk Factors and Special Considerations" starting on page 41.

(1) Shareholders who buy $1 million in shares without paying a sales charge may
    be charged a contingent deferred sales charge of 1% on redemptions made
    within one year of purchase. See "Contingent Deferred Sales Charge" in this
    prospectus.
   
(2) The Investment Adviser has agreed to waive or defer its management fees and
    to absorb other operating expenses payable by the Fund. For Class A, B & C,
    Total operating expenses would have been 3.00%, 6.44% and 2.83%
    respectively, and Other expenses would have been 2.00%, 4.94% and 1.33%
    respectively, absent the deferral. See "Investment Adviser Compensation."
    
    Because of the 12b-1 fee, long-term shareholders may indirectly pay more
than the equivalent of the maximum permitted front-end sales charge. #

FULLY DISCRETIONARY FUND
 
INVESTMENT OBJECTIVE
 
    Seeks maximum total return.
 
INVESTMENT STRATEGY
 
    The Fund's Investment Adviser seeks to outperform the total return of an
index of either government/ corporate investment grade debt or
government/corporate/ mortgage investment grade debt over a full market cycle
through an actively managed diversified portfolio of debt securities. When
evaluating any bond, the Investment Adviser selects bonds based upon a "top
down" analysis of economic trends. Investment philosophy emphasizes interest
rate decisions and shifts among sectors of the bond market. It also analyzes
credit quality, the yield to maturity of the security, and the effect the
security will have on the Fund.
 
PRINCIPAL INVESTMENTS
 
    Under normal conditions, the Fund invests at least 65% of its total assets
in investment grade debt securities issued by U.S. and foreign corporations,
U.S. and foreign governments, and their agencies and instrumentalities. These
securities include bonds, notes, mortgage backed and asset backed securities
with rates that are fixed, variable or floating. The Fund may invest up to 20%
of its assets in debt securities rated below investment grade by a nationally
recognized statistical rating agency, or of comparable quality if unrated. For a
description of these ratings, see "corporate bond ratings" beginning on page 45.
The Fund may also use options, futures contracts and interest rate and currency
swaps as hedging techniques. The average portfolio duration of the Fund will
range from two to eight years. The Fund may invest up to 30% of its total assets
in securities payable in foreign currencies.
 
PORTFOLIO MANAGEMENT
 
    The Investment Adviser emphasizes a team approach to portfolio management to
maximize its overall effectiveness. For a complete list of the portfolio team,
see "Portfolio Teams" on page 37.
 
RISK FACTORS
 
    As with any fund that invests in bonds, the value of the Fund's investments
fluctuates in response to movements in interest rates. If interest rates go up,
the value of bonds fall; if rates go down, the value of bonds rise. However, the
Investment Adviser expects the Fund's fluctuations to be more moderate than
those of a fund with a longer average duration. The lower rated debt securities
in which the Fund invests are considered speculative and are subject to greater
volatility and risk of loss than investment grade securities, particularly in
deteriorating economic periods. To the extent the Fund invests in foreign
securities, performance also depends upon changing currency values, different
political and economic environments, and other overall economic conditions in
countries where the Fund invests. For further explanation, see "Risk Factors and
Special Considerations" starting on page 41.

INVESTOR EXPENSES--CLASS A, B AND C SHARES
 
    Investors pay various expenses, either directly or indirectly. Actual
expenses may be more or less than those shown.

</TABLE>
 
- ------------------------
 
(1) Shareholders who buy $1 million in shares without paying a sales charge may
    be charged a contingent deferred sales charge of 1% on redemptions made
    within one year of purchase. See "Contingent Deferred Sales Charge" in this
    prospectus.
 
(2) The Investment Adviser has agreed to waive or defer its management fees and
    to absorb other operating expenses payable by the Fund. For Class A, B & C,
    Total operating expenses are expected to be 7.73%, 8.38% and 5.03%,
    respectively, and Other expenses are expected to be 7.38%, 7.93% and 4.58%
    respectively, absent the deferral. See "Investment Adviser Compensation."
 
Because of the 12b-1 fee, long-term shareholders may indirectly pay more than
the equivalent of the maximum permitted front-end sales charge.

HIGH YIELD BOND FUND
 
INVESTMENT OBJECTIVE
 
    High level of current income and capital growth.
 
INVESTMENT STRATEGY
 
    The Fund invests primarily in lower rated debt securities commonly referred
to as "junk bonds." When evaluating any bond, the Investment Adviser selects
bonds based upon a combination of both "top down" analysis of economic trends
and "bottom-up" analysis that evaluates the financial condition and
competitiveness of individual companies. It also analyzes credit quality, the
yield to maturity of the security, and the effect the security will have on the
average yield to maturity of the Fund. The Investment Adviser believes it can
lower the risks of investing in lower rated debt through these professional
management techniques and through diversification.
 
PRINCIPAL INVESTMENTS
 
    Under normal conditions, the Fund allocates at least 65% of its total assets
in lower rated debt securities and convertible securities rated below investment
grade by a nationally recognized statistical rating agency, or of comparable
quality if unrated. There is no limit on either the portfolio maturity or the
acceptable rating of securities bought by the Fund. For a description of these
ratings, see "Corporate Bond Ratings" beginning on page 45. Securities may bear
rates that are fixed, variable or floating. The Fund may invest up to 35% of its
total assets in equity securities of U.S. and foreign companies. The Fund is not
restricted to investments in companies of any particular size, but currently
intends to invest principally in companies with market capitalization above $100
million at the time of purchase. The Fund may also use options, futures
contracts and interest rate and currency swaps as hedging techniques.
 
PORTFOLIO MANAGEMENT
 
    The Investment Adviser emphasizes a team approach to portfolio management to
maximize its overall effectiveness. For a complete list of the portfolio team,
see "Portfolio Teams" on page 37.
 
RISK FACTORS
 
    As with any fund that invests primarily in bonds, the value of the Fund's
investments fluctuates in response to movements in interest rates. When rates go
up, debt security prices fall; when rates go down, debt security prices rise.
Lower rated securities, while usually offering higher yields, generally have
more risk and volatility than higher rated securities because of reduced
creditworthiness and greater chance of default. Periods of high interest rates
and recession may adversely affect the issuer's ability to pay interest and
principal. To the extent the Fund invests in stocks, the value of those
investments will fluctuate day to day with movements in the stock market as well
as in response to the activities of individual companies. The companies in which
the Fund invests may be more subject to volatile market movements than
securities of larger, more established companies. To the extent the Fund invests
in foreign securities, performance also depends on changes in foreign currency
values, different political and regulatory environments, and overall economic
factors in the countries where the Fund invests. For further explanation, see
"Risk Factors and Special Considerations" starting on page 41.
 
INVESTOR EXPENSES--CLASS A, B AND C SHARES
 
    Investors pay various expenses, either directly or indirectly. Actual

</TABLE>
 
- ------------------------
 
(1) Shareholders who buy $1 million in shares without paying a sales charge may
    be charged a contingent deferred sales charge of 1% on redemptions made
    within one year of purchase. See "Contingent Deferred Sales Charge" in this
    prospectus.
 
(2) The Investment Adviser has agreed to waive or defer its management fees and
    to absorb other operating expenses payable by the Fund. For Class A, B & C,
    Total operating expenses are expected to be 2.25%, 2.85% and 2.85%,
    respectively, and Other expenses are expected to be 1.50%, 2.10% and 2.10%
    respectively, absent the deferral. See "Investment Adviser Compensation."
 
Because of the 12b-1 fee, long-term shareholders may indirectly pay more than
the equivalent of the maximum permitted front-end sales charge.

MONEY MARKET FUND
 
INVESTMENT OBJECTIVE
 
    High current income consistent with preservation of capital and maintenance
of liquidity.
 
INVESTMENT STRATEGY
 
    The Fund's Investment Adviser invests only in securities that mature in 397
days or less, and are rated in one of the two highest short term rating
categories by one or more nationally recognized statistical rating organization,
or in comparable unrated securities. The Fund maintains a dollar weighted
portfolio average maturity of 90 days or less.
 
PRINCIPAL INVESTMENTS
 
    The Fund invests in high-quality, short-term U.S. dollar denominated money
market instruments that comply with the credit quality and diversification
requirements of Rule 2a7 under the Investment Company Act, which regulates money
market funds. These include obligations issued or guaranteed by the U.S.
Government, its agencies or instrumentalities; certificates of deposit, time
deposits and bankers' acceptances of certain domestic and foreign banks and
domestic savings and loan associations; commercial paper and other short term
corporate obligations; and repurchase agreements. Certain of the acceptable debt
instruments may be credit enhanced by a guaranty, letter of credit, or
insurance.
 
PORTFOLIO MANAGEMENT
 
    The Investment Adviser emphasizes a team approach to portfolio management to
maximize its overall effectiveness. For a complete list of the portfolio team,
see "Portfolio Teams" on page 37.
 
RISK FACTORS
 
    Although the Fund seeks to preserve the value of your investment at $1.00
per share, it is possible to lose money by investing in the Fund. As with any
money market fund, there is the risk that the issuers or guarantors of
securities owned by the Fund will default on the payment of principal or
interest or the obligation to repurchase securities from the Fund. Neither the
Fund nor the portfolio is insured or guaranteed by the U.S. Government. For
further explanation, see "Risk Factors and Special Considerations" starting on
page 41.

CLASS C SHARES
 
    Shareholders who redeem Class C Shares within one full year of the purchase
date may be charged a CDSC of 1%.
 
MONEY MARKET FUND
 
    A CDSC may be charged on redemptions of shares purchased through an 
exchange of Class B or C Shares of an investor who did not own the Class B 
Shares for six full years or the Class C Shares for one full year, whichever 
is applicable.
 
    There is no CDSC imposed on shares acquired through reinvestment of
dividends or capital gains.
 
    The CDSC will be imposed on the lesser of the original purchase price or 
the net asset value of the redeemed shares at the time of redemption. CDSC 
calculations are based on the numbers of shares involved, not the value of 
your account. To keep your CDSC as low as possible, each time you place a 
request to sell shares we will first sell any shares in your account that 
represent reinvested dividends/capital gains and then shares that satisfy the 
holding period. If there are not enough of these to meet your request, we 
will sell your shares on a first in, first out basis. Your financial 
institution may elect to waive some or all of the payment thereby reducing 
the otherwise applicable CDSC.
 
SALES CHARGE REDUCTIONS AND WAIVERS
 
REDUCING YOUR CLASS A SALES CHARGES.
 
    There are several ways you can combine multiple purchases of shares of Class
A Shares to take advantage of the breakpoints in the sales charge schedule.
These can be combined in any manner:
 
- -  ACCUMULATION PRIVILEGE -- lets you add the value of Class A Shares you and
    your immediate family already own to the amount of your next investment for
    purposes of calculating the sales charge.
 
                                       30
<PAGE>

- -  LETTER OF INTENT -- lets you purchase Class A Shares over a 13 month period
    and receive the same sales charge as if all shares had been purchased at
    once.
 
- -  COMBINATION PRIVILEGE -- lets you combine Class A Shares for purposes of
    reducing the sales charge.
 
    TO UTILIZE: COMPLETE THE APPROPRIATE SECTION ON YOUR APPLICATION, OR CONTACT
YOUR FINANCIAL REPRESENTATIVE OR NICHOLAS-APPLEGATE MUTUAL FUNDS TO ADD THESE
OPTIONS TO AN EXISTING ACCOUNT.
 
    CDSC WAIVERS. In general, the CDSC may be waived on shares you sell for the
following reasons:
 
- -  make payments through certain systematic withdrawal plans
 
- -  qualifying distributions from qualified retirement plans and other employee
    benefit plans
 
- -  distributions from custodial accounts under section 403(b)(7) of the Internal
    Revenue Code as well as IRAs due to death, disability or attainment of age
    59 1/2
 
    TO UTILIZE: CONTACT YOUR FINANCIAL REPRESENTATIVE OR NICHOLAS-APPLEGATE
MUTUAL FUNDS, OR CONSULT THE SAI (SEE THE BACK COVER OF THIS PROSPECTUS).
 
    REINSTATEMENT PRIVILEGE.  If you sell Class A Shares, you may invest some or
all of the proceeds in the same class within 90 days without a sales charge. If
you paid a CDSC when you sold your shares, you will be credited with the amount
of the CDSC. All accounts involved must have the same registration.
 
    TO UTILIZE: CONTACT YOUR FINANCIAL REPRESENTATIVE OR NICHOLAS-APPLEGATE
MUTUAL FUNDS.
 
    NET ASSET VALUE PURCHASES.  Class A Shares may be sold at net asset value
to:
 
    (1) current or retired directors, trustees, partners, officers and employees
of the Trust, the Distributor, the Investment Adviser and its general partner,
certain family members of the above persons, and trusts or plans primarily for
such persons;
 
    (2) current or retired registered representatives or full time employees and
their spouses and minor children and plans of such persons;
 
    (3) former limited partners and participants of certain investment
partnerships and pooled trusts previously managed by the Investment Adviser;
 
    (4) investors who exchange their shares from an unaffiliated investment
company which has a sales charge, so long as shares are purchased within 60 days
of the redemption;
 
    (5) trustees or other fiduciaries purchasing shares for certain retirement
plans of organizations with 50 or more eligible employees;
 
    (6) Investment Advisers and financial planners who place trades for their
own accounts or the accounts of their clients either individually or through a
master account and who charge a management, consulting or other fee for their
services;
 
    (7) employee sponsored benefit plans in connection with purchases of Class A
Shares made as a result of participant directed exchanges between options in
such a plan;
 
    (8) "wrap accounts" for the benefit of clients of broker dealers, financial
institutions or financial planners having sales or service agreements with the
distributor or another broker-dealer or financial institution with respect to
sales of Class A Shares; and

    (9) such other persons as are determined by the Board of Trustees (or by the
distributor pursuant to guidelines established by the board) to have acquired
shares under circumstances not involving any sales expense to the trust or the
distributor.
 
DISTRIBUTION PLAN AND SHAREHOLDER SERVICES
 
    Each Fund has adopted a distribution plan in accordance with Rule 12b-1
under the Investment Company Act. Class B and C Shares may pay a fee to the
Distributor in an amount computed at an annual rate of .75% of the average daily
net assets to finance any activity which is principally intended to result in
the sale of shares. Class A Shares may pay the Distributor a fee equal to .25%
of the average daily net assets, and the Money Market Fund may pay up to .15% of
the average daily net assets. The schedule of such fees and the basis upon which
such fees will be paid will be determined from time to time by the distributor.
 
    Each of the Funds has entered into a Shareholder Services Agreement with the
Distributor under which each Fund will reimburse the Distributor up to .25% of
the average daily assets of each of the Portfolios to pay financial institutions
for certain personal services for shareholders and for the maintenance of
shareholder accounts.
 
    In addition to the payments described above, the distributor may also pay
additional compensation to financial institutions in connection with selling
shares of the Funds. Compensation may include financial assistance for
conferences, shareholder services, computer software, training programs or
promotional activities. The distributor offers additional compensation to
financial institutions that the distributor expects will sell a significant
amount of shares. Financial institutions may obtain more information by calling
(800) 551-8045.

  A definition         A signature guarantee is required of a financial institution to verify the authenticity
                                     of an individual's signature. It can usually be obtained from
                                         a broker, commercial or savings bank, or credit union.

When you need one       A signature guarantee is needed when making a written request for the following reasons:
                                          1. When selling more than $50,000 worth of shares;
                                2. When you want a check or bank wire sent to a name or address that is not 
                                                   currently listed on the account;
                            3. To sell shares from an account controlled by a corporation, partnership, trust 
                                                           or fiduciary; or

                                                        account with the same registration.
                             If opening an account as part of an exchange, you must obtain and read the prospectus. If
                             you intend to keep money in the Fund you are exchanging from, make sure that you leave an
                               amount equal to or greater than the Fund's minimum account size (see the "Opening an
                                                                Account" section).
                               To protect other investors, the Trust may limit the number of exchanges you can make.

YOUR ACCOUNT
 
TRANSACTION POLICIES
 
    VALUATION OF SHARES.  The net asset value per share (NAV) for the Fund is
determined each business day at the close of regular trading on the New York
Stock Exchange (usually 4 p.m. Eastern Time) by dividing the Class' net assets
by the number of its shares outstanding.
 
    BUY AND SELL PRICES.  When you buy shares, you pay the NAV, as described
earlier. When you sell shares, you receive the NAV. Your financial institution
may charge you a fee to execute orders on your behalf.
 
    EXECUTION OF REQUESTS.  Each Fund is open on the days the New York Stock
Exchange is open, usually Monday-Friday. Buy and sell requests are executed at
the NAV next calculated after your request is received in good order by the
transfer agent or another agent designated by the trust.
 
    At times of peak activity, it may be difficult to place requests by phone.
During these times, consider sending your request in writing. Each Fund reserves
the right to reject any purchase or to suspend or modify the continuous offering
of its shares. Your financial representative is responsible for forwarding
payment promptly to the transfer agent. The Trust reserves the right to cancel
any buy request if payment is not received within three days.
 
    In unusual circumstances, any Fund may temporarily suspend the processing of
sell requests, or may postpone payment of proceeds for up to three business days
or longer, as allowed by federal securities laws.
 
    TELEPHONE TRANSACTIONS.  For your protection, telephone requests may be
recorded in order to verify their accuracy. In addition, the Trust will take
measures to verify the identity of the caller, such as asking for name, account
number, Social Security or taxpayer ID number and other relevant information. If
these measures are not taken, your Fund may be responsible for any losses that
may occur in your account due to an unauthorized telephone call.
 
    EXCHANGES.  You may exchange shares of any Class for shares of the same
Class (A, B, or C) of any other Fund, generally without paying any additional
sales charges. You may also exchange shares of any Fund for shares of the Money
Market Portfolio. Class C shares purchased through an exchange from a like Class
will continue to age from the original date and will retain the same CDSC rate
as they had before the exchange. The holding period of Money Market Fund shares
purchased through an exchange from Class B or C shares is excluded from the
calculation of the holding period on Class B and C shares.
 
    To protect the interests of other investors in a Fund, the trust may cancel
the exchange privileges of any parties that, in the opinion of the Investment
Adviser, are using market timing strategies that adversely affect the Fund.
Guidelines for exchanges are available from the distributor upon request. A Fund
may also refuse any exchange order.
 
    CERTIFICATED SHARES.  Most shares are electronically recorded. If you wish
to have certificates for your shares, please write to the transfer agent.
Certificated shares can only be sold by returning the certificates to the
transfer agent, along with a letter of instruction or a stock power and a
signature guarantee.
 
    SALES IN ADVANCE OF PURCHASE PAYMENTS.  When you place a request to sell
shares for which the purchase money has not yet been collected, the request will
be executed in a timely fashion, but the Fund will not release the proceeds to
you until your purchase payment clears. This may take up to fifteen calendar
days after the purchase.
 
    SHAREHOLDER INQUIRIES.  Shareholder inquiries should be addressed to the
Trust, c/o the Trust's transfer agent,
 
    State Street Bank and Trust Company 
    Attention: Nicholas-Applegate Mutual Funds 
    P.O. Box 8326 
    Boston, Ma 02266-8326

    Telephone inquiries can be made by calling 1-800-551-8043 or, from outside
the U.S., 1-617-774-5000 (collect).
 
                         FEATURES AND ACCOUNT POLICIES
 
    The services referred to in this section may be terminated or modified at
any time upon 60 days' written notice to shareholders. Shareholders seeking to
add to, change or cancel their selection of available services should contact
the transfer agent at the address and telephone number provided above.
 
    RETIREMENT PLANS.  You may invest in each Fund through various retirement
plans, including IRAs, Simplified Employee Plan (SEP) IRAs, 403(b) plans, 457
plans, and all qualified retirement plans. For further information about any of
the plans, agreements, applications and annual fees, contact the Distributor,
your financial representative or plan sponsor. To determine which retirement
plan is appropriate for you, consult your tax adviser.
 
    ACCOUNT STATEMENTS.  In general, you will receive account statements as
follows:
 
    - After every transaction that affects your account balance.
 
    - After any changes of name or address of the registered owner(s).
 
    - In all other circumstances, every quarter.
 
    Every year you will also receive an applicable tax information statement,
mailed by January 31.

    DIVIDENDS.  The Funds generally distribute most or all of their net earnings
in the form of dividends. Each Fund pays dividends as follows:

    DIVIDEND REINVESTMENTS.  If you choose this option, or if you do not
indicate any choice, your dividends will be reinvested on the ex-dividend date.
Alternatively, you can choose to have a check for your dividends mailed to you.
Interest will not accrue or be paid on uncashed dividend checks.
 
    SHAREHOLDER SERVICES.  The Investment Adviser may make payments from its own
resources to brokers, consultants and financial institutions for performing
certain services for shareholders and for the maintenance of shareholder
accounts.
 
    TAXABILITY OF DIVIDENDS.  As long as a Fund meets the requirements for being
a tax-qualified regulated investment company, which each Fund has in the past
and intends to in the future, it pays no federal income tax on the earnings it
distributes to shareholders.
 
    Consequently, dividends you receive from a Fund whether reinvested or taken
as cash, are generally considered taxable. Dividends from a Fund's long-term
capital gains are taxable as capital gains; dividends from other sources are
generally taxable as ordinary income.

    Some dividends paid in January may be taxable as if they had been paid the
previous December. Corporations may be entitled to take a dividends received
deduction for a portion of certain dividends they receive.
 
    The tax information statement that is mailed to you details your dividends
and their federal tax category, although you should verify your tax liability
with your tax professional.
 
    TAXABILITY OF TRANSACTIONS.  Any time you sell or exchange shares, it is
considered a taxable event for you. Depending on the purchase price and the sale
price of the shares you sell or exchange, you may have a gain or a loss on the
transaction. You are responsible for any tax liabilities generated by your
transactions.
 
    SMALL ACCOUNTS (NON-RETIREMENT ONLY). If you draw down a non-retirement
account so that its total value is less than the Fund minimum, you may be asked
to purchase more shares within 60 days. If you do not take action, the Fund may
close out your account and mail you the proceeds. Your account will not be
closed if its drop in value is due to Fund performance.
 
    AUTOMATIC WITHDRAWALS.  You may make automatic withdrawals from a Fund of
$50 or more on a monthly or quarterly basis if you have an account of $5,000 or
more in the Fund. Withdrawal proceeds will normally be received prior to the end
of the month or quarter. See the account application for further information.
 
    AUTOMATIC INVESTMENT PLAN.  You may make regular monthly or quarterly
investments in Class A, B and C Shares of each Fund through automatic
withdrawals of specified amounts from your bank account once an automatic
investment plan is established. See the account application for further details
about this service or call the Transfer Agent at 1-800-551-8043.
 
    CROSS-REINVESTMENT. You may cross-reinvest dividends or dividends and
capital gains distributions paid by one Fund into Class A, B and C Shares of
another Fund, subject to conditions outlined in the Statement of Additional
Information and the applicable provisions of the qualified retirement plan.
   
    CONVERSION OF CLASS B FUND SHARES.  Class B shares in a Fund will
automatically be exchanged for Class A shares of such Fund seven years after
purchase. Exchanges will be made at relative net asset value free of any charges
and will not constitute a taxable event for income tax purposes. The amount of
time shares are held in the Money Market Fund will be excluded from the
calculation of the holding period.

ORGANIZATION AND MANAGEMENT
 
INVESTMENT ADVISER COMPENSATION
   
    Each Fund pays the Investment Adviser a fee pursuant to an investment
advisory agreement. The Emerging Countries Fund pays an advisory fee at the
annual rate of 1.25% of the Fund's net assets. The Worldwide, International Core
Growth and International Small Cap Funds each pay an advisory fee at the annual
rate of 1.00% on the first $500 million of each Fund's net assets, .90% on the
next 500 million of each Fund's net assets, and .85% on net assets on each Fund
in excess of $1 billion. The Fully Discretionary Fund pays at the annual rate of
0.45% of the first $500 million of the Fund's average net assets, 0.40% of the
next $250 million of net assets, and 0.35% of net assets in excess of $750
million. The High Yield Bond Fund pays at the annual rate of 0.60% of the Fund's
net assets. The Emerging Growth Fund pays at the annual rate of 1.00% of the
Fund's net assets. The Large Cap Growth, Core Growth, Value, Income & Growth,
and Balanced Growth Funds each pay at the annual rate of 0.75% of the first $500
million of the Fund's net assets, 0.675% of the next $500 million of net assets,
and 0.65% of net assets in excess of $1 billion.
 
    The Investment Adviser has agreed to waive or defer its management fees
payable by the Funds, and to absorb other operating expenses of the Funds and
the Portfolios, so that the expenses for the Portfolio will not exceed the
following expense ratios on an annual basis through March 31, 1998: Worldwide
Growth Class A, B & C--1.85%, 2.50%, and 2.50%; International Small Cap Growth
Class A, B & C-- 1.95%, 2.60% and 2.60%; Emerging Countries--Class A, B &
C--2.25%, 2.90% and 2.90%; International Core Growth Class A, B & C--1.95%,
2.60% and 2.60%; Income & Growth, Balanced Growth, Large Cap, Value, Core Growth
and High Yield Bond Class A, B & C--1.60%, 2.25% and 2.25%; Emerging Growth
Class A, B & C -1.95%, 2.60% and 2.60%; Fully Discretionary Class A, B &
C--0.95%, 1.35% and 1.35%; and Money Market Fund--1.10%. Each Portfolio will
reimburse the Investment Adviser for fees deferred or other expenses paid
pursuant to this Agreement in later years in which operating expenses for the
Fund are less than the percentage limitation set forth above for any such year.
    

ADMINISTRATOR COMPENSATION
   
    The Funds pay administrative fees for administrative personnel and services
(including certain legal and financial reporting services). Each Fund pays
Nicholas-Applegate Capital Management an annual fee of .10% of net assets. Each
Fund pays Investment Company Administration Corporation (ICAC) an annual fee at
an annual rate ranging from .05% to .01% of average net assets, with a minimum
of $40,000 per Fund.

PORTFOLIO TRADES
 
    The Investment Adviser is responsible for the Funds' portfolio transactions.
In placing portfolio trades, the Investment Adviser may use brokerage firms that
sell shares of the Fund or that provide research services to the Fund, but only
when the Investment Adviser believes no other firm offers a better combination
of quality execution (i.e. timeliness and completeness) and favorable price. The
Investment Adviser expects high annual portfolio turnover up to 200%. This is
generally higher than other Funds and will result in the Funds incurring higher
brokerage costs.
 
INVESTMENT OBJECTIVE
   
    Each Fund's investment objective is fundamental and may only be changed with
shareholder approval. The other fundamental limitations are described in the
Statement of Additional Information. All other changes may be made by the Board
of Trustees without shareholder approval.
    

DIVERSIFICATION
 
    All the Funds are diversified.
 
PRIOR MASTER-FEEDER STRUCTURE
   
    Prior to Febuary 27, 1998, the various classes of each of the Funds were
separate Portfolios of the Trust, and invested all of their assets in
corresponding portfolios of Nicholas-Applegate Investment Trust (the "Master
Trust"). In this "master-feeder" structure, the Investment Adviser served as the
adviser to the Master Trust, and the Trust had no separate adviser. The
"master-feeder" structure was terminated, with the approval of the shareholders
of the Trust, in order to achieve certain economies for the Trust.

RISK FACTORS AND SPECIAL CONSIDERATIONS
 
MUTUAL FUND CONSIDERATIONS IN GENERAL
 
    Prospective investors should know that any mutual fund investment is 
subject to market fluctuations and other risks inherent in investing in 
securities. There can be no assurance that your investment will increase in 
value. The value of your investment will go up and down depending upon market 
forces and you may not recoup your original investment. You should consider 
an investment in any of the Funds a long-term investment.
 
DERIVATIVE CONTRACTS AND SECURITIES CONSIDERATIONS
   
    The term "derivative" traditionally applies to certain contracts that 
"derive" their value from changes in the value of underlying securities, 
currencies, commodities or indices. Investors refer to certain types of 
securities that incorporate the performance characteristics of these 
contracts as derivatives. Derivatives are sophisticated instruments that 
typically involve a small investment of cash relative to the magnitude of 
risks assumed. These include swap agreements, options, futures, and 
convertible securities. The Funds seek to use derivative contracts and 
securities to reduce volatility and increase total performance. While the 
price reaction of certain derivatives to market changes may differ from 
traditional investments such as stocks and bonds, derivatives do not 
necessarily present greater market risks than traditional investments. 
Derivatives are also subject to credit risks related to the counterparty's 
ability to perform, and any deterioration in the counterparty's 
creditworthiness could adversely affect the instrument. The Funds will only 
use derivatives in a manner consistent with their investment objectives, 
policies and limitations.
    

GLOBAL INVESTING CONSIDERATIONS
 
    CURRENCY FLUCTUATIONS. Because the assets in each Fund may be invested in 
instruments issued by foreign companies, the principal, income and sales 
proceeds may be paid to the Funds in local foreign currencies. A reduction in 
the value of local currencies relative to the U.S. dollar could mean a 
corresponding reduction in the value of the Funds. The value of a foreign 
security generally tends to decrease when the value of the U.S. dollar rises 
against the foreign currency in which the security is denominated and tends 
to increase when the value of the dollar falls against such currency. The 
Funds may incur costs in connection with conversions between currencies.
 
    SOCIAL, POLITICAL AND ECONOMIC FACTORS. The economies of many of the 
countries where the Funds may invest may be subject to a substantially 
greater degree of social, political and economic instability than the United 
States. Such instability may result from, among other things, the following: 
authoritarian governments; popular unrest associated with demands for 
improved political, economic and social conditions; internal insurgencies and 
terrorist activities; hostile relations with neighboring countries; and drug 
trafficking. This instability might impair the financial conditions of 
issuers or disrupt the financial markets in which the Funds invest.
 
    The economies of foreign countries may differ favorably or unfavorably 
and significantly from the economy of the United States in such respects as 
the rate of growth of gross domestic product, rate of inflation, currency 
depreciation, savings rates, fiscal balances, and balance of payments 
positions. Governments of many foreign countries continue to exercise 
substantial control over private enterprise and own or control many 
companies. Government actions could have a significant impact on economic 
conditions in certain countries which could affect the value of the 
securities of the Funds. For example, a foreign country could nationalize an 
entire industry. In such a case, the Funds may not be fairly compensated for 
their losses and might lose their entire investment in the country involved.
 
    The economies of certain foreign countries are heavily dependent upon 
international trade and accordingly are affected by protective trade barriers 
and the economic conditions of their trading partners. The enactment by the 
United States or other principal trading partners of protectionist 
legislation could have a significant adverse effect on the securities markets 
of these countries. Some foreign countries (mostly in Africa and Latin 
America) are large debtors of commercial banks, foreign governments, and 
supranational organizations. These obligations, as well as future 
restructurings of debt, may affect the economic performance and political and 
social stability of these countries.
   
    Hong Kong transferred its sovereignty from Great Britain to the People's 
Republic of China in 1997. China has espoused policies antagonistic to free 
enterprise capitalism and democracy. There can be no assurance that China 
will continue to protect property rights in Hong Kong after 1997, although 
China has moved toward free enterprise, and has established stock exchanges 
of its own.
    

                                     41

RISK FACTORS AND SPECIAL CONSIDERATIONS
 
    INFLATION. Certain foreign countries, especially many emerging countries, 
have experienced substantial, and in some periods extremely high and 
volatile, rates of inflation. Rapid fluctuations in inflation rates and wage 
and price controls may continue to have unpredictable effects on the 
economies, companies and securities markets of these countries.
 
MARKET CHARACTERISTICS
 
    DIFFERENCES IN SECURITIES MARKETS. The securities markets in foreign 
countries have substantially less trading volume than the markets in the 
United States and debt and equity securities of many companies listed on such 
markets may be less liquid and more volatile than comparable securities in 
the United States. Some of the stock exchanges in foreign countries, to the 
extent that established markets exist, are in the earlier stages of their 
development. The limited liquidity of certain securities markets may affect 
the ability of each Fund to buy and sell securities at the desired price and 
time. In addition, the securities markets of some foreign countries are 
susceptible to being influenced by large investors trading significant blocks 
of stocks.
 
    Trading practices in certain foreign countries are also significantly 
different from those in the United States. Local commercial, corporation and 
securities laws govern the sale and resale of securities, and certain 
restrictions may apply. Although brokerage commissions are generally higher 
than those in the U.S., the Investment Adviser will seek to achieve the most 
favorable net results. In addition, securities settlements and clearance 
procedures may be less developed and less reliable than those in the United 
States. Delays in settlement could result in temporary periods in which the 
assets of the Funds are not fully invested, or could result in a Fund being 
unable to sell a security in a falling market.
 
    CUSTODIAL AND REGISTRATION PROCEDURES. Systems for the registration and 
transfer of securities in foreign markets can be less developed than similar 
systems in the United States. There may be no standardized process for 
registration of securities or a central registration system to track share 
ownership. The process for transferring shares may be cumbersome, costly, 
time-consuming and uncertain. For example, the share registrar may require a 
shareholder to travel to that country to present required documentation 
before buying or selling securities. In some instances, there may be no 
requirements to maintain back-up shareholder records. Failure by the share 
registrar to properly maintain shareholder records, protect the same against 
fire or computer virus, or carry adequate insurance against such occurrences, 
potentially could result in a loss of a Fund's investment in those securities.
 
    GOVERNMENT SUPERVISION OF SECURITIES MARKETS. Disclosure and regulatory 
standards in many foreign countries are in many respects less stringent than 
those in the United States. There may be less government supervision and 
regulation of securities exchanges, listed companies, investors, and brokers 
in foreign countries than in the United States, and enforcement of existing 
regulations may be extremely limited.
 
    FINANCIAL INFORMATION AND REPORTING STANDARDS. Issuers in foreign 
countries are generally subject to accounting, auditing, and financial 
standards and requirements that differ, in some cases materially, from those 
in the United States. In particular, the assets and profits appearing in 
financial statements may not reflect their financial position or results in 
the way they would be reflected had the statements been prepared in 
accordance with U.S. generally accepted accounting principles. Consequently, 
financial data may not reflect the true condition of those issuers and 
securities markets.
 
    LOWER RATED SECURITIES CONSIDERATIONS. The Balanced Growth, Income & 
Growth, Fully Discretionary and High Yield Bond Funds each invest in debt and 
convertible securities below investment grade. These securities usually offer 
higher yields than higher rated securities but are also subject to more risk 
than higher rated securities. Lower rated or unrated debt obligations are 
more likely to react to developments affecting market and credit risks that 
are more high rated securities, which react primarily to movements in the 
past level of interest rates. In the past, economic downturns or increases in 
interest rates caused a higher incidence of default by issuers of lower-rated 
securities.
 
    In some cases, such obligations may be highly speculative, and may have 
poor prospects for reaching investment grade. To the extent the issuer 
defaults, the Fund may incur additional expenses in order to enforce its 
rights or to participate in a restructuring of the obligation. In addition, 
the prices of lower-rated securities generally tend to be more volatile and 
the market less liquid than those of higher-rated securities. Consequently, 
the Funds may at times experience difficulty in liquidating their investments 
at the desired times and prices.
   
    The average percentages of assets invested by the Funds listed below in 
bonds of each permissible rating, on a monthly dollar-weighted basis, were as 
follows for the nine month period ended December 31, 1997: Income & 
Growth--AA-      %; A-      %; BBB-      %; BB-      %; B-      %; CCC-      
%; non-rated-      %; Balanced Growth--AA-      %; A-      %; BBB-      %; 
BB-      %; B-      %; CCC-      %; non-rated-      %; Fully 
Discretionary--AA-      %; A-   %; BBB-      %; BB-      %; B-      %; CCC-   
   %; non-rated-      %; and High Yield Bond-- AA-   %; A-      %; BBB-      
%; BB-      %; B-      %; CCC-      %; non-rated-      %. A description of 
the rating categories is contained in this prospectus.

THE FUNDS' INVESTMENTS
 
    EQUITY SECURITIES. Equity securities include common stocks, convertible 
securities and warrants. The Funds may invest in growth companies, cyclical 
companies, companies with smaller market capitalizations, or companies 
believed to be undergoing a basic change in operations or markets. Although 
equity securities have a history of long-term growth in value, their prices 
rise and fall as a result of changes in the company's financial condition as 
well as movements in the overall securities markets.
 
    SMALLER ISSUERS. Smaller and medium sized issuers may be less seasoned, 
have more limited product lines, markets, financial resources and management 
depth, and be more susceptible to adverse market conditions than larger 
issuers. As a result, the securities of such smaller issuers may be less 
actively traded than those of larger issuers and may also experience greater 
market volatility. CONVERTIBLE SECURITIES. A convertible security is a fixed 
income equity security that may be converted into a prescribed amount of 
common stock at a specified formula. A convertible security entitles the 
owner to receive interest until the security matures or is converted. 
Convertibles have several unique investment characteristics such as: (a) 
higher yields than common stocks but lower yields than straight debt 
securities; (b) lesser degree of fluctuation in value than the underlying 
stock since they have fixed income characteristics; and (c) potential for 
capital appreciation if the market price of the underlying security increases.
 
    CORPORATE DEBT SECURITIES. Corporate debt securities are subject to the 
risk of an issuer's inability to meet principal and interest payments on the 
obligation (credit risk) and may also be subject to price volatility due to 
such factors as interest rate sensitivity, market perception of the 
credit-worthiness of the issuer and general market liquidity (market risk). 
When interest rates decline, the value of the Funds' debt securities can be 
expected to rise, and when interest rates rise, the value of those securities 
can be expected to decline. Debt securities with longer maturities tend to be 
more sensitive to interest rate movements than those with shorter maturities.
 
    Debt obligations carry a rating of at least Baa from Moody's or BBB from 
Standard and Poor's, or a comparable rating from another rating agency or, if 
not rated by an agency, determined by the Investment Adviser to be of 
comparable quality. Bonds rated BBB or Baa may have speculative 
characteristics and changes in economic circumstances are more likely to lead 
to a weakened capacity to make interest and principal payments than higher 
rated bonds. For a further explanation of these ratings, see the Statement of 
Additional Information.
 
    U.S. GOVERNMENT SECURITIES. U.S. Government securities are obligations 
issued or guaranteed by the U.S. Government, its agencies or 
instrumentalities. Some U.S. Government securities such as U.S. Treasury 
bills, notes, bonds, and certificates issued by the Government National 
Mortgage Association (GNMA) are supported by the full faith and credit of the 
United States. Other U.S. Government securities, such as securities issued by 
the Federal National Mortgage Association (FNMA) and the Federal Home Loan 
Bank Board, are supported by the right of the issuer to borrow from the U.S. 
Treasury. Still others, such as the Student Loan Marketing Association, are 
supported only by the credit of the issuer. U.S. Government securities may 
include zero coupon securities that are issued or purchased at a significant 
discount from face value.
 
    ZERO COUPON SECURITIES. The Income & Growth and Balanced Growth Funds may 
invest up to 35% of their net assets in zero coupon securities issued or 
guaranteed by the U.S. Government and its agencies and instrumentalities. 
These securities are sold at a substantial discount from face value and 
redeemed at face value at their maturity date without interim payments of 
principal and interest. They may be subject to greater volatility than other 
securities. In addition, because income is accrued on a current basis, a Fund 
may have to sell other portfolio securities to make necessary income 
distributions.
 
    MORTGAGE-RELATED SECURITIES. Collateralized Mortgage Obligations (CMO's) 
are debt obligations collateralized by a pool of mortgage loans or mortgage 
passes-through securities. Typically CMOs are collateralized by certificates 
issued or guaranteed by the U.S. Government, its agencies or 
instrumentalities, such as GNMA. GNMA certificates are mortgaged-backed 
securities representing part ownership of a pool of mortgage loans, which are 
issued by lenders such as mortgage bankers, commercial banks, and savings 
associations, and are either insured by the federal housing administration or 
the veterans administration.
 
    ASSET BACKED SECURITIES. The non-mortgage-related asset-backed securities 
in which the High Yield Bond and Fully Discretionary Funds invest include, 
but are not limited to, interests in pools of receivables, such as credit 
card and accounts receivables and motor vehicle and other installment 
purchase obligations and leases. Interests in these pools are not backed by 
the U.S. Government and may or may not be secured.
   
    The credit characteristic of asset -backed securities differs in a number 
of respects from that of traditional debt securities. Asset-backed securities 
generally do not have the benefit of a security interest in collateral that 
is comparable to other debt obligations, and there is a possibility that 
recoveries on repossessed collateral may not be available to support payment 
on these securities.

<PAGE>

RISK FACTORS AND SPECIAL CONSIDERATIONS
   
    SOVEREIGN DEBT SECURITIES. Certain Funds may invest in sovereign debt 
securities issued by governments of foreign countries. The sovereign debt in 
which the Funds may invest may be rated below investment grade. These 
securities usually offer higher yields than higher rated securities but are 
also subject to greater risk than higher rated securities.
 
    BRADY BONDS. Brady bonds represent a type of sovereign debt. These 
obligations were created under a debt restructuring plan introduced by former 
U.S. Secretary of the Treasury, Nicholas F. Brady, in which foreign entities 
issued these obligations in exchange for their existing commercial bank 
loans. Brady Bonds have been issued by Argentina, Brazil, Costa Rica, 
Dominican Republic, Mexico, Philippines, Uruguay and Venezuela, and may be 
issued by other emerging countries.
    

    INVESTMENT COMPANY SECURITIES. Each Fund may invest up to 10% of its 
total assets in the shares of other investment companies. The Funds may 
invest in money market mutual Funds in connection with the management of 
their daily cash positions. The Funds may also make indirect foreign 
investments through other investment companies that have comparable 
investment objectives and policies as the Funds. In addition to the advisory 
and operational fees each Fund bears directly in connection with its own 
operation, the Funds would also bear their pro rata portions of each other 
investment company's advisory and operational expenses.
 
    ILLIQUID SECURITIES. Each Fund may invest up to 15% of its net assets in 
securities that are considered illiquid. An illiquid investment is generally 
an investment that is not registered in the under U.S. securities laws, or 
cannot be disposed of within seven days in the normal course of business at 
approximately the amount at which the Fund values it. Limitations on resale 
may adversely affect the marketability of illiquid securities and the Fund 
may not be able to dispose of these securities at the desired time and price. 
A Fund may bear additional expenses if it has to register these securities 
under U.S. securities laws before being resold.
 
    TEMPORARY INVESTMENTS. The Funds may from time to time on a temporary 
basis to maintain liquidity or when the Investment Adviser determines that 
the market conditions call for a temporary defensive posture, invest all of 
their assets in short-term instruments. These temporary investments include: 
notes issued or guaranteed by the U.S. Government, its agencies or 
instrumentalities; commercial paper rated in the highest two rating 
categories; certificates of deposit; repurchase agreements and other high 
grade corporate debt securities.
 
THE FUNDS' INVESTMENT TECHNIQUES
 
    REPURCHASE AGREEMENTS. Each Fund may enter into repurchase agreements, 
that is the purchase by the Fund of a security that seller has agreed to buy 
back, usually within one to seven days. The seller's promise to repurchase 
the security is fully collateralized by securities equal in value to 102% of 
the purchase price, including accrued interest. If the seller defaults and 
the collateral value declines, the Fund might incur a loss. If the seller 
declares bankruptcy, the Fund may not be able to sell the collateral at the 
desired time. The Funds enter into these agreements only with brokers, 
dealers, or banks that meet credit quality standards established by the Board 
of Trustees.
 
    SECURITIES SWAPS. Securities swaps represent a technique primarily used 
to indirectly participate in the securities market of a country from which a 
Fund would otherwise be precluded for lack of an established securities 
custody and safekeeping system. The Fund deposits an amount of cash with its 
custodian (or the broker, if legally permitted) in an amount equal to the 
selling price of the underlying security. Thereafter, the Fund pays or 
receives cash from the broker equal to the change in the value of the 
underlying security.
 
    SHORT SALES. A "short sale" is the sale by the Fund of a security which 
has been borrowed from a third party on the expectation that the market price 
will drop. If the price of the security drops, the Fund will make a profit by 
purchasing the security in the open market at lower price than at which it 
sold the security. If the price of the security rises, the Fund may have to 
cover its short position at a higher price than the short sale price, 
resulting in a loss. A short sale can be covered or uncovered. In a covered 
short sale, the Fund either (1) borrows and sells securities it already owns 
(also known as a short sale "against the box"), or (2) deposits in a 
segregated account cash, U.S. Government securities, or other liquid 
securities in an amount equal to the difference between the market value of 
the securities and the short sale price. Use of uncovered short sales is a 
speculative investment technique and has potentially unlimited risk. 
Accordingly, a Fund will not make uncovered short sales in an amount 
exceeding the lesser of 2% of the Fund's net assets or 2% of the securities 
of such class of the issuer. The Board of Trustees has determined that no 
Fund will make short sales if to do so would create liabilities or require 
collateral deposits of more than 25% of the Fund's total assets.
 
    WHEN ISSUED AND DELAYED DELIVERY TRANSACTIONS. Each Fund may purchase or 
sell securities for delivery at a future date, generally 15 to 45 days after 
the commitment is made. The other party's failure to complete the transaction 
may cause the Fund to miss a price or yield
 
                                       44

<PAGE>

considered to be advantageous. A Fund may not purchase when issued securities 
or enter into firm commitments if, as a result, more than 15% of the Fund's 
net assets would be segregated to cover such securities.
 
    BORROWING. Each Fund may borrow up to 20% of its total assets for 
temporary, extraordinary or emergency purposes. Each Fund may also borrow 
money through reverse repurchase agreements, uncovered short sales, and other 
techniques. All borrowings by a Fund cannot exceed one-third of a Fund's 
total assets. As a consequence of borrowing, a Fund will incur obligations to 
pay interest, resulting in an increase in expenses.
 
    SECURITIES LENDING. Each Fund may lend securities to financial 
institutions such as banks, broker/ dealers and other recognized 
institutional investors in amounts up to 30% of the Fund's total assets. 
These loans earn income for the Fund and are collateralized by cash, 
securities, letters of credit or any combination thereof. The Fund might 
experience loss if the financial institution defaults on the loan.
 
    FOREIGN CURRENCY TRANSACTIONS. Each Fund investing in foreign securities 
may enter in to foreign currency transactions either on a spot or cash basis 
at prevailing rates or through forward foreign currency exchange contracts in 
order to have the necessary currencies to settle transactions. Each such Fund 
may also enter into foreign currency transactions to protect Fund assets 
against adverse changes in foreign currency exchange rates. Such efforts 
could limit potential gains that might result from a relative increase in the 
value of such currencies, and might, in certain cases, result in losses to a 
Fund.
   
    OPTIONS. Each Fund may deal in options on securities, securities indices 
and foreign currencies. The Funds may use options to manage stock prices, 
interest rate and currency risks. A Fund may not purchase or sell options if 
more than 25% of its net assets would be hedged. The Funds may also write 
covered call options and secured put options to seek to generate income or 
lock in gains on up to 25% of their net assets.
 
    FUTURES AND OPTIONS ON FUTURES. Each Fund may enter into futures 
contracts, or options thereon, involving foreign currency, interest rates, 
securities, and securities indices, for hedging purposes only. A stock index 
futures contract is a bilateral agreement pursuant to which two parties agree 
to take or make delivery of an amount of cash equal to a specified dollar 
amount times the difference between the stock index value at the close of the 
last trading day of the contract and the price at which the futures contract 
is originally struck. No physical delivery of the underlying stocks in the 
index is made. As a general rule, no Fund will purchase or sell futures if, 
immediately thereafter, more than 25% of its net assets would be hedged.
    

    RISKS OF FUTURES AND OPTIONS TRANSACTIONS. When a Fund uses options, 
futures and options on futures as hedging devices, there is a risk that the 
prices of the hedging vehicles may not correlate perfectly with the prices of 
the securities in the portfolio. This may cause the futures contract and any 
related options to react differently than the Fund's portfolio securities to 
market changes. In addition, the Investment Adviser could be incorrect in its 
expectations about the direction or the extent of market movements. In these 
events, a Fund could lose money on the futures contracts or option.
 
    It is not certain that a secondary market for positions in futures 
contracts or for options will exist at all times. Although the Investment 
Adviser will consider liquidity before entering into these transactions, 
there is no assurance that a liquid secondary market will exist for these 
instruments.
   
    NON-HEDGING STRATEGIC TRANSACTIONS. Each Fund's options, futures and swap 
transactions will generally be entered into for hedging purposes--to protect 
against possible changes in the market values of securities held in or to be 
purchased for the Fund's Portfolio resulting from securities markets, 
currency, or interest rate fluctuations, to protect the Fund's unrealized 
gains in the values of its portfolio securities, to facilitate the sale of 
such securities for investment purposes, to manage the effective maturity or 
duration of the Fund's portfolio, or to establish a position in the 
derivatives markets as a temporary substitute for purchase or sale of 
particular securities. However, in addition to the hedging transactions 
referred to above, the Fully Discretionary Fund may enter into options, 
futures and swap transactions to enhance potential gain in circumstances 
where hedging is not involved. The Fund's net loss exposure resulting from 
transactions entered into for such purposes will not exceed 5% of the Fund's 
net assets at any one time and , to the extent necessary, the Fund will close 
out transactions in order to comply with this limitation. Such transactions 
are subject to the limitations described above under "Options" and "Futures 
and Options on Futures."
    

CORPORATE BOND RATINGS
 
DESCRIPTION OF MOODY'S CORPORATE BOND RATINGS
 
    Aaa--Bonds rated Aaa are judged to be of the best quality. They carry the 
smallest degree of investment risk and are generally referred to as "gilt 
edge." Interest payments are protected by a large or by an exceptionally 
stable margin and principal is secure. While the various protective elements 
are likely to change, such changes are most unlikely to impair the 
fundamentally strong position of such issues.
 
                                      45

<PAGE>

RISK FACTORS AND SPECIAL CONSIDERATIONS
 
    Aa--Bonds rated Aa are judged to be high quality by all standards. 
Together with the Aaa group they comprise what are generally known as 
high-grade bonds. They are rated lower than the best bonds because margins of 
protection may not be as large as in Aaa securities or fluctuation of 
protective elements may be of greater amplitude or other elements present 
which make the long-term risks appear somewhat larger than in Aaa securities.
 
    A--Bonds rated A possess many favorable investment attributes and are to 
be considered as upper-medium-grade obligations. Factors giving security to 
principal and interest are considered adequate but elements may be present 
which suggest a susceptibility to impairment sometime in the future.
 
    Baa--Bonds rated Baa are considered medium-grade obligations (i.e., they 
are neither highly protected nor poorly secured). Interest payments and 
principal security appear adequate for the present but certain protective 
elements may be lacking or may be characteristically unreliable over any 
great length of time. Such bonds lack outstanding investment characteristics 
and in fact have speculative characteristics as well.
 
    B--Bonds rated B generally lack characteristics of the desirable 
investment. Assurance of interest and principal payments or maintenance of 
other terms of the contract over any long period of time may be small.
 
    Caa--Bonds rated Caa are of poor standing. Such issues may be in default 
or there may be present elements of danger with respect to principal or 
interest.
 
    Ca--Bonds rated Ca represent obligations which are speculative in a high 
degree. Such issues are often in default or have other marked short-comings.
 
    C--Bonds rated C are the lowest-rated class of bonds, and such issues can 
be regarding as having extremely poor prospects of ever attaining any real 
investment standing.
 
    Moody's applies numerical modifiers, 1, 2, and 3, in each generic rating 
classification from Aa through B in its corporate bond rating system. The 
modified 1 indicates that the security ranks in the higher end of its generic 
rating category; the modifier 2 indicates a mid range ranking; and the 
modifier 3 indicates that the issue ranks in the lower end of its generic 
rating category.
 
DESCRIPTION OF S&P'S CORPORATE BOND RATINGS
 
    AAA--Debt rated aaa has the highest rating assigned by Standard & Poor's 
to a debt obligation. Capacity to pay interest and repay principal is 
extremely strong.
 
    AA--Debt rated AA has a very strong capacity to pay interest and repay 
principal and differs from the higher-rated issues only in small degree.
 
    A--Debt rated A has a strong capacity to pay interest and repay 
principal, although it is somewhat more susceptible to the adverse
 
    Effects of changes in circumstances and economic conditions than debt in 
higher rated categories.
 
    BBB--Debt rated BBB is regarded as having an adequate capacity to pay 
interest and repay principal. Whereas it normally exhibits adequate 
protection parameters, adverse economic conditions or changing circumstances 
are more likely to lead to a weakened capacity to pay interest and repay 
principal for debt in this category than in higher-rated categories.
 
    BB--Debt rated BB has less near-term vulnerability to default than other 
speculative issues. However, it faces major ongoing uncertainties or exposure 
to adverse business, financial or economic conditions which could lead to 
inadequate capacity to meet timely interest and principal payments. The BB 
rating category is also used for debt subordinated to senior debt that is 
assigned an actual or implied BBB rating.
 
                                      46

<PAGE>

    B--Debt rated B has a greater vulnerability to default but currently has 
the capacity to meet interest payments and principal repayments. Adverse 
business, financial, or economic conditions will likely impair capacity or 
willingness to pay interest and repay principal. The B rating category is 
also used for debt subordinated to senior debt that is assigned an actual or 
implied BB--rating.
 
    CCC--Debt rated CCC has a currently identifiable vulnerability to 
default, and is dependent upon favorable business, financial and economic 
conditions to meet timely payment of interest and repayment of principal. In 
the event of adverse business financial or economic conditions, it is not 
likely to have the capacity to pay interest and repay principal. The CCC 
rating category is also used for debt subordinated to senior debt that is 
assigned an actual or implied B or B -rating.
 
    CC--Debt rated CC is typically applied to debt subordinated to senior 
debt which is assigned an actual or implied CCC debt rating.
 
    C--The rating C is typically applied to debt subordinated to senior debt 
which is assigned an actual or implied CCC-debt rating. The C rating may be 
used to cover a situation where a bankruptcy petition has been filed, but 
debt service payments are continued.
 
    CI--The rating CI is reserved for income bonds on which no interest is 
being paid.
 
    D--Debt rated D is in payment default. The d rating category is used when 
interest payments or principal payments are not made on the date due even if 
the applicable grace period has not expired, unless S&P believes that such 
payments will be made during such grace period. The D rating will also be 
used upon the filing of a bankruptcy petition if debt service payments are 
jeopardized.
 
    The ratings from AA to CCC may be modified by the addition of a plus or 
minus sign to show relative standing within the major rating categories.

Item 27.  INDEMNIFICATION.

          Registrant's trustees, officers, employees and agents against
liabilities incurred by them in connection with the defense or disposition of
any action or proceeding in which they may be involved or with which they may be
threatened, while in office or thereafter, by reason of being or having been in
such office, except with respect to matters as to which it has been determined
that they acted with willful misfeasance, bad faith, gross negligence or
reckless disregard of the duties involved in the conduct of their office
("Disabling Conduct").

          Section 8 of Registrant's Administration Agreement, filed herewith as
Exhibit 9.1, provides for the indemnification of Registrant's Administrator
against all liabilities incurred by it in performing its obligations under the
Agreement, except with respect to matters involving its Disabling Conduct.
Section 9 of Registrant's Distribution Agreement, filed herewith as Exhibit 6,
provides for the indemnification of Registrant's Distributor against all
liabilities incurred by it in performing its obligations under the Agreement,
except with respect to matters involving its Disabling Conduct.  Section 4 of
the Shareholder Service Agreement, filed herewith as Exhibit 9.3, provides for
the indemnification of Registrant's Distributor against all liabilities incurred
by it in performing its obligations under the Agreement, except with respect to
matters involving its Disabling Conduct.

          Registrant has obtained from a major insurance carrier a trustees' and
officers' liability policy covering certain types of errors and omissions.

          Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to trustees, officers and controlling
persons of the Registrant pursuant to the foregoing provisions, or otherwise,
the Registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Securities Act and is, therefore, unenforceable.  In the event that a
claim for indemnification against such liabilities (other than the payment by
the Registrant of expenses incurred or paid by a trustee, officer or controlling
person of the Registrant in the successful defense of any action, suit or
proceeding) is asserted by such trustee, officer, or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.
