We live in an era of constant, dramatic change. The world's marketplaces are
transforming into a single interconnected community with the integration of the
European Union, economic deregulation and privatization in Latin America, the
technological coming of age in the Pacific Rim and the new entrepreneurial boom
in the United States.
 
At Nicholas-Applegate, we see these changes creating a wealth of investment
opportunities, which we seek out company by company. By expanding our global
reach, we believe we can help you find promising investments throughout the
world.
 
I hope you will join Nicholas-Applegate in our quest for opportunities
worldwide.

GOAL OF THE NICHOLAS-APPLEGATE MUTUAL FUNDS
The Nicholas-Applegate Mutual Funds (the "Trust") are designed to provide
investors with a well-rounded investment program by offering investors various
portfolios each with different investment objectives and policies (each a
"Fund"). The Class A, B and C Shares of each Fund represent interests in a
diversified, open-end management investment company (a mutual fund).

disclosures carefully before investing.

investment adviser to the Funds. Arthur E. Nicholas and 22 other partners with a
staff of approximately 480 employees currently manage over $30 billion of
discretionary assets for numerous clients, including employee benefit plans of
corporations, public retirement systems and unions, university endowments,
foundations, and other institutional investors and individuals.

   INTERNATIONAL CORE GROWTH FUND
 
INVESTMENT OBJECTIVE
 
Maximum long-term capital appreciation.
 
INVESTMENT STRATEGY
 
The 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
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 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 invests in the larger capitalized companies in each country. Generally,
this means issuers in each country whose stock market capitalizations are in the
top 75% of publicly traded companies as measured by capitalizations in that
country.
 
PRINCIPAL INVESTMENTS
 
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 debt securities of any maturity of foreign companies and
foreign governments and their agencies and instrumentalities which are rated
investment grade by a nationally recognized statistical rating agency, or of
comparable quality if unrated. 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 39.
 
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. To the extent
the Fund invests in countries with emerging markets, the risks are magnified
since these countries may have unstable governments and less established
markets. For further explanation, see "Risk Factors and Special Considerations"
starting on page 42.
 
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 pay other operating expenses (excluding interest, taxes, brokerage
     commissions and other portfolio transaction expenses, capital expenditures
     and extraordinary expenses) otherwise payable by the Fund, subject to
     possible later reimbursement during a five year period. For Class A, B & C,
     Management fees would have been 1.00%, 1.00% and 1.00%, respectively, Total
     operating expenses would have been 3.02%, 3.04% and 5.10%, respectively,
     and Other expenses would have been 1.77%, 1.29% and 3.35%, 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 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
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 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 debt securities of any maturity issued by foreign companies and
foreign governments and their agencies and instrumentalities which are rated
investment grade by a nationally recognized statistical rating agency, or of
comparable quality if unrated. 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 39.
 
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 global 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. To the extent the Fund invests
in countries with emerging markets the risks are magnified, since these
countries may have unstable governments and less established markets. The
securities of small, less well-known companies may be more volatile than those
of larger companies. For a further explanation, see "Risk Factors and Special
Considerations" starting on page 42.
 
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 pay other operating expenses (excluding interest, taxes, brokerage
     commissions and other portfolio transaction expenses, capital expenditures
     and extraordinary expenses) otherwise payable by the Fund, subject to
     possible later reimbursement during a five year period. For Class A, B & C,
     Management fees would have been 1.00%, 1.00% and 1.00%, respectively, Total
     operating expenses would have been 2.21%, 2.70% and 2.77%, respectively,
     and Other expenses would have been 0.96%, 0.95% and 1.02%, 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.

   INTERNATIONAL SMALL CAP GROWTH FUND
 
INVESTMENT OBJECTIVE
 
Maximum long-term capital appreciation.
 
INVESTMENT STRATEGY
The 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 countries throughout the world, 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 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 stock market capitalizations in each country ("small cap
securities").
 
PRINCIPAL INVESTMENTS
Under normal conditions, the Fund invests at least 65% of its total assets in
small cap 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 stock, warrants and convertible securities. It invests the
remainder primarily in debt securities of any maturity issued by foreign
companies and foreign governments and their agencies and instrumentalities which
are rated investment grade by a nationally recognized statistical rating agency,
or of comparable quality if unrated. 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 39.
 
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, information regarding smaller
companies may be less available, incomplete or inaccurate, and their securities
may trade less frequently than those of larger companies. 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 42.
 
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 pay other operating expenses (excluding interest, taxes, brokerage
     commissions and other portfolio transaction expenses, capital expenditures
     and extraordinary expenses) otherwise payable by the Fund, subject to
     possible later reimbursement during a five year period. For Class A, B & C,
     Management fees would have been 1.00%, 1.00% and 1.00%, respectively, Total
     operating expenses would have been 2.75%, 2.98% and 3.38%, respectively,
     and Other expenses would have been 1.50%, 1.23% and 1.63%, 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 35 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 and Venezuela.
    
 
Under normal market 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 debt securities of foreign companies and
foreign governments and their agencies and instrumentalities which are rated
investment grade by a nationally recognized statistical rating agency, or of
comparable quality if unrated. 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 39.
 
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. The securities of small, less well known
companies may be more volatile than those of larger companies. For further
explanation, see "Risk Factors and Special Considerations" starting on page 42.

   LARGE CAP GROWTH FUND
 
INVESTMENT OBJECTIVE
 
Long-term capital appreciation.
 
INVESTMENT STRATEGY
 
The 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 invests primarily in stocks from a universe of U.S. companies with
market capitalizations corresponding to the upper 90% of the Russell 1000 Growth
Index at time of purchase. As of June 30, 1998, the bottom 10% of the Index
included companies with capitalizations less than $3.9 billion. Capitalization
of companies in the Index will change with market conditions.
 
PRINCIPAL INVESTMENTS
 
Under normal conditions, the Fund invests at least 65% of its total assets in
securities of large capitalization U.S. companies, including common and
preferred stocks, warrants, and convertible securities. It invests the remainder
primarily in corporate debt securities of any maturity which are rated
investment grade by a nationally recognized statistical rating agency, or of
comparable quality if unrated, 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 39.
 
RISK FACTORS
 
As with any growth fund, 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. To the extent the Fund is overweighted in certain market
sectors compared to the Standard & Poor's 500 Stock Index (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 42.
 
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 pay other operating expenses (excluding interest, taxes, brokerage
     commissions and other portfolio transaction expenses, capital expenditures
     and extraordinary expenses) otherwise payable by the Fund, subject to
     possible later reimbursement during a five year period. For Class A, B & C,
     Management fees would have been 0.75%, 0.75% and 0.75%, respectively, Total
     operating expenses would have been 4.70%, 4.78% and 7.79%, respectively,
     and Other expenses would have been 3.70%, 3.28% and 6.29%, 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.

   MID CAP GROWTH FUND
  (FORMERLY CORE GROWTH FUND)
 
INVESTMENT OBJECTIVE
 
Maximum long-term capital appreciation.
 
INVESTMENT STRATEGY
 
The 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 invests at least 65% of its total assets in stocks from a universe of
U.S. companies with market capitalizations corresponding to the middle 90% of
the Russell Midcap Growth Index at time of purchase. As of June 30, 1998, the
middle 90% included companies with capitalizations between $1.6 billion and
$10.7 billion. Capitalization of companies in the Index will change with market
conditions.
    
 
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, debt securities of any maturity which are rated
investment grade by a nationally recognized statistical rating agency, or of
comparable quality if unrated, 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 39.
 
RISK FACTORS
 
As with any growth fund, 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 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 42.

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 pay other operating expenses (excluding interest, taxes, brokerage
     commissions and other portfolio transaction expenses, capital expenditures
     and extraordinary expenses) otherwise payable by the Fund, subject to
     possible later reimbursement during a five year period. For Class A, B & C,
     Management fees would have been 0.75%, 0.75% and 0.75%, respectively, Total
     operating expenses would have been 1.66%, 2.21% and 2.33%, respectively,
     and Other expenses would have been 0.66%, 0.71% and 0.83%, 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.

   VALUE FUND
 
   
INVESTMENT OBJECTIVE
    
 
   
Long-term capital appreciation.
    
 
INVESTMENT STRATEGY
 
   
The Fund's Investment Adviser employs a disciplined, "bottom-up" approach that
evaluates stocks on an individual basis and focuses on company fundamentals. It
uses a blend of computer-intensive systematic disciplines and traditional
fundamental research to uncover stocks that meet three investment criteria:
attractive valuations, underlying financial strength, and prospects for business
improvement.
    
 
   
The Fund emphasizes equity securities of undervalued, large U.S. 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, debt securities of any maturity which are rated
investment grade by a nationally recognized statistical rating agency, or of
comparable quality if unrated, 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.
 
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 39.
 
RISK FACTORS
As with any equity fund, 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. 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 42.

   SMALL CAP GROWTH FUND
  (FORMERLY EMERGING GROWTH FUND)
 
INVESTMENT OBJECTIVE
 
Maximum long-term capital appreciation.
 
INVESTMENT STRATEGY
 
The 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 invests at least 65% of its total assets in stocks from a universe of
U.S. companies with market capitalizations corresponding to the middle 90% of
the Russell 2000 Growth Index at time of purchase. As of June 30, 1998, the
middle 90% included companies with capitalizations between $255 million and $1.4
billion. Capitalization of companies in the Index will change with market
conditions.
    
 
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, debt securities of any maturity which are rated investment grade by
a nationally recognized statistical rating agency, or of comparable quality if
unrated, 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 39.
 
RISK FACTORS
As with any growth fund, 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. 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 42.

     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 pay other operating expenses (excluding interest, taxes, brokerage
     commissions and other portfolio transaction expenses, capital expenditures
     and extraordinary expenses) otherwise payable by the Fund, subject to
     possible later reimbursement during a five year period. For Class A, B & C,
     Management fees would have been 1.00%, 1.00% and 1.00%, respectively, Total
     operating expenses would have been 1.90%, 2.63% and 2.59%, respectively,
     and Other expenses would have been 0.65%, 0.88% and 0.84%, 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.

   CONVERTIBLE FUND
  (FORMERLY INCOME & GROWTH FUND)
 
INVESTMENT OBJECTIVE
 
Maximum total return, consisting of 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 emphasizes companies with market capitalizations above $500 million.
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. For a description of these
ratings, see "Corporate Bond Ratings" beginning on page 45.
 
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 39.
 
RISK FACTORS
 
Convertible securities have the investment characteristics of both equity and
debt securities. Accordingly, the value of the Fund's investments varies in
response to movements in the stock and bond markets. Stock prices fluctuate in
response to the activities of individual companies and general market and
economic conditions. 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 changes as interest rates
fluctuate: if rates rise, the value of debt securities fall; if rates fall, the
value of debt securities rise. In addition, the lower rated debt 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 42.

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 pay other operating expenses (excluding interest, taxes, brokerage
     commissions and other portfolio transaction expenses, capital expenditures
     and extraordinary expenses) otherwise payable by the Fund, subject to
     possible later reimbursement during a five year period. For Class A, B & C,
     Management fees would have been 0.75%, 0.75% and 0.75%, respectively, Total
     operating expenses would have been 1.74%, 2.33% and 2.31%, respectively,
     and Other expenses would have been 0.74%, 0.83% and 0.81%, 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. For a description of these ratings, see
"Corporate Bond Ratings" beginning on page 45. 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 39.
 
RISK FACTORS
 
As with any fund that invests in common stocks and debt obligations, the value
of the Fund's investments varies in response to movements in the stock and bond
markets. Stock prices fluctuate in response to the activities of individual
companies and general market and economic conditions. 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 changes as
interest rates fluctuate: if rates rise, the value of debt securities fall; if
rates fall, the value of debt securities rise. In addition, 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 42.
 
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 pay other operating expenses (excluding interest, taxes, brokerage
     commissions and other portfolio transaction expenses, capital expenditures
     and extraordinary expenses) otherwise payable by the Fund, subject to
     possible later reimbursement during a five year period. For Class A, B & C,
     Management fees would have been 0.75%, 0.75% and 0.75%, respectively, Total
     operating expenses would have been 2.56%, 2.71% and 2.68%, respectively,
     and Other expenses would have been 1.56%, 1.21% and 1.18%, 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 QUALITY BOND FUND
  (FORMERLY FULLY DISCRETIONARY FIXED INCOME 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 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
debt securities issued by U.S. and foreign corporations, U.S. and foreign
governments, and their agencies and instrumentalities which are rated in the top
two investment grades by a nationally recognized statistical rating agency, or
of comparable quality if unrated. These securities include bonds, notes,
mortgage backed and asset backed securities with rates that are fixed, variable
or floating. 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.
    
 
The Fund may invest up to 20% of its assets in debt securities rated below
investment grade. For a description of these ratings, see "Corporate Bond
Ratings" beginning on page 47. 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 39.
 
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 rise,
the prices of debt securities fall; if rates fall, the prices of debt securities
rise. However, the Investment Adviser expects the Fund's fluctuations to be more
moderate than those of a fund with a longer average duration. In addition, 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 42.

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 pay other operating expenses (excluding interest, taxes, brokerage
     commissions and other portfolio transaction expenses, capital expenditures
     and extraordinary expenses) otherwise payable by the Fund, subject to
     possible later reimbursement during a five year period. For Class A, B & C,
     Management fees are expected to be 0.45%, 0.45% and 0.45%, respectively,
     Total operating expenses are expected to be 5.93%, 4.82% and 3.82%,
     respectively, and Other expenses are expected to be 5.23%, 3.87% and 2.87%,
     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 invests 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 47. 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 39.
 
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
rise, debt security prices fall; when rates fall, 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 42.

   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 39.
 
RISK FACTORS
Although the Fund seeks to preserve the value of a shareholder's 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 42.

 Shareholders who redeem Class C Shares within one full year of
 the purchase date may be charged a CDSC of 1%.
 
                    MONEY MARKET FUND SHARES
 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.
 
/ / 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. 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

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.

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 0.75% 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
0.25% of the average daily net assets, and the Money Market Fund may pay up to
0.15% 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 0.25%

amount of shares. Financial institutions may obtain more information by calling

                                  recently by check, payment may be delayed until the check clears, which may take up to 15
                                 calendar days from the date of purchase. Sales by a corporation, trust or fiduciary may have
                                          special requirements. Please contact your financial representative, a plan
                                                     administrator/sponsor or us for further information.

   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 value of 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.
 
OTHER SHARE CLASSES. Certain Funds also offer Class I and Q shares. The Class I
and Q shares have no sales charges and have other expenses which may result in
performance for those Classes which is different from that of Class A, B and C
shares. You can obtain more information about Class I and Q shares from
Nicholas-Applegate Securities at (800) 551-8643.
 
SHAREHOLDER INQUIRIES. Shareholder inquiries should be addressed to the Trust,

457 plans, and all qualified retirement plans. For further information about any

the form of dividends. Each Fund pays dividends as follows:

Any net capital gains are distributed annually.
 
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.
 
Dividends you receive from a Fund, whether reinvested or taken as cash, are
generally 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.

C-- 1.72%, 2.60% and 2.35%; High Quality Bond Class A, B & C--0.95%, 1.35% and
1.35%; High Yield Bond Class A, B & C--1.10%, 1.75% and 1.75%; and Money Market
Fund--0.70%*. Each Fund 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. The Investment Adviser will not recover any fee
waivers or expense reimbursements from a Fund more than five years after the
expenses were incurred (March 31, 2003 in the case of expenses incurred prior to
March 31, 1998).
    
 
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 a monthly fee at the annual rate of 0.10%
of average net assets. Each Fund pays Investment Company Administration
Corporation a monthly fee at an annual rate ranging from 0.05% to 0.01% of
average net assets, with a minimum of $40,000 per Fund.
 
DISTRIBUTOR:
 
Nicholas-Applegate Securities
600 West Broadway, 30th Floor
San Diego, California 92101
(800) 551-8045
 
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 July 24, 1998, the various classes of most 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.
 
INTERNATIONAL 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 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.
 
A number of Asian countries are currently experiencing economic difficulties and
significant declines in values in their financial markets as a result of the
rapid convergence in those countries, beginning in the fourth quarter of 1997,
of a number of the social, political and economic risk factors referred to
above. The unsettled condition of several Asian financial markets has also
affected emerging markets in other countries and regions. These conditions could
continue or deteriorate further in the future.
<PAGE>
                                                                              43
 
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.
 
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. Securities rated below investment grade
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 than
are more high rated securities, which react primarily to movements in 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
<PAGE>

   RISK FACTORS AND SPECIAL CONSIDERATIONS
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 (as rated by Standard & Poor's Corporation), on a
monthly dollar-weighted basis, were as follows for the year ended March 31,
1998: Convertible-- AAA-1.87%; AA-2.21%; A-9.57%; BBB-12.46%; BB-9.57%; B-8.80%;
CCC-0.13%; non-rated-9.05%; Balanced Growth--AAA-21.02%; AA-1.60%; A-4.31%;
BBB-1.94%; BB-0.26%; B-2.29%; CCC-0.99%; CC-0.01%; non-rated-1.55%; High Quality
Bond--AAA-61.28%; AA-5.35%; A-10.57%; BBB-5.29%; BB-1.81%; B-4.87%; CCC-0.67%;
CC-0.15%; non-rated-2.94%; and High Yield Bond--BB-10.41%; B-47.74%; CCC-11.29%;
non-rated-17.16%. 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
the 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 that are deemed investment grade 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, are determined by the
Investment Adviser to be of comparable quality. Bonds rated Baa or BBB 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
"Corporate Bond Ratings" beginning on page 45.
 
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 securities of 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. 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 ("CMOs") are
debt obligations collateralized by a pool of mortgage loans or mortgage
<PAGE>
                                                                              45
 
pass-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.
The rate of prepayment of underlying mortgage loans in a pool rises when
interest rates fall and falls when interest rates rise. Accordingly, it is not
possible to predict accurately the average life of a particular pool.
 
ASSET BACKED SECURITIES. The non-mortgage-related asset-backed securities in
which certain 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 characteristics of asset-backed securities differs in a number of
respects from those 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.
 
   
SOVEREIGN DEBT SECURITIES. Sovereign debt securities are 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, the Dominican Republic,
Mexico, the 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 a Fund bears
directly in connection with its own operation, the Fund would also bear its pro
rata portions of each other investment company's advisory and operational
expenses.
 
   
ILLIQUID SECURITIES. Each Fund may invest up to 15% (except the Money Market
Fund which may invest up to 10%) of its net assets in securities that are
considered illiquid. An illiquid investment is generally an investment that is
not registered 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. The
Board of Trustees has determined that Rule 144A securities are not illiquid
securities.
    
 
TEMPORARY INVESTMENTS. Each Fund may, from time to time on a temporary basis,
invest all of its assets in short-term instruments to maintain liquidity or when
the Investment Adviser determines that the market conditions call for a
temporary defensive posture. 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. Repurchase agreements are the purchase by the Fund of a
security that the 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. A securities swap is a technique primarily used to indirectly
participate in the securities market of a country from which a Fund would
<PAGE>
46
 
   RISK FACTORS AND SPECIAL CONSIDERATIONS
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 a 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 of loss. 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 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. Interest
costs on borrowings may fluctuate with changing market rates of interest and may
partially offset or exceed the return earned on borrowed funds (or on the assets
that were retained rather than sold to meet the needs for which funds were
borrowed). Under adverse market conditions, a Fund might have to sell portfolio
securities to meet interest or principal payments at a time when fundamental
investment considerations would not favor such sales.
 
   
SECURITIES LENDING. The Funds may lend securities only 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 or letters of credit. The Fund
might experience a 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. Options on securities, securities indices and foreign currencies may be
used to manage market, 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. A futures contract obligates the seller of the
contract to deliver and the purchaser of the contract to take delivery of the
type of foreign currency, financial instrument or security called for in the
contract at a specified future time for a specified price. 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
<PAGE>
                                                                              47
 
perfectly with the prices of the portfolio securities being hedged. 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. Although the Investment Adviser will consider liquidity
before entering into these transactions, there is no assurance that a liquid
secondary market will exist for positions in futures contracts or for options at
all times.
 
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 High Quality Bond
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."
 
THE YEAR 2000
 
The Investment Adviser has taken steps that it believes are reasonably designed
to address the potential failure of computer programs used by the Investment
Adviser and the Trust's service providers to address the Year 2000 issue. There
can be no assurance that these steps will be sufficient to avoid any adverse
impact.
 
In addition, the Year 2000 problem may adversely affect the Funds' investments.
For example, portfolio companies may incur substantial costs to address the
problem. They may also suffer losses caused by corporate and governmental data
processing errors.
 
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.
 
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.
 
Ba - Bonds rated Ba are judged to have speculative elements; their future cannot
be considered well-assured. Often the protection of interest and principal
payments may be very moderate, and thereby not well safeguarded during both good
and bad times over the future. Uncertainty of position characterizes bonds in
this class.
 
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.
<PAGE>
48
 
   RISK FACTORS AND SPECIAL CONSIDERATIONS
 
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.
 
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.

   PRIOR PERFORMANCE OF CERTAIN FUNDS AND THEIR PREDECESSORS
 
    The following table sets forth historical performance information for the
Class A, B and C shares of the Mid Cap Growth, Convertible and International
Small Cap Growth Funds. It includes historical performance information for the
A, B and C Portfolios which preceded the Funds prior to the reorganization of
the Trust in March, 1998, for the corresponding master funds of the Master Trust
which were operated by the Investment Adviser prior to the organization of such
A, B and C Portfolios, and for the following investment partnerships which
preceded such master funds: Mid Cap Growth Fund--includes performance
information for Whitehall Partners, a California limited partnership the assets
of which were transferred to the predecessor of the Mid Cap Growth Fund in
April, 1993; Convertible Fund--includes performance information for Coventry
Partners, a California limited partnership the assets of which were transferred
to the predecessor of the Convertible Fund in April, 1993; International Small
Cap Growth Fund--includes performance information for Huntington Partners, a
California limited partnership the assets of which were transferred to the
predecessor of the International Small Cap Growth Fund in January, 1994.
 
    All information set forth in the table relies on data supplied by the
Investment Adviser or from statistical services, reports or other sources
believed by the Investment Adviser to be reliable. However, such information has
not been verified and is unaudited. See "Performance Information" in the
Statement of Additional Information for information about calculation of total
return.
 
   
    The Investment Adviser has advised the Trust that such partnerships were
operated with materially equivalent investment objectives, policies, strategies
and restrictions as such A, B and C Portfolios, and their assets were
transferred to the corresponding master funds of the Master Trust prior to the
effective date of the Portfolios' registration statement. It has indicated that
such results for the prior partnerships and for the corresponding master funds
of the Master Trust, have been adjusted to reflect the deduction of the fees and
expenses of the A, B and C Portfolios (including Rule 12b-1 fees), and, for the
period preceding the reorganization of the Trust, the proportionate shares of
the operating expenses of the corresponding master funds of the Master Trust
(including advisory fees), and give effect to transaction costs (such as sales
loads) as well as reinvestment of income and gains. However, the prior
investment partnerships were not registered under the 1940 Act and were not
subject to certain investment restrictions imposed by such Act; if they had been
so registered, their performance might have been adversely affected.
    
 
    The results presented on the following pages may not necessarily equate with
the return experienced by any particular shareholder or partner as a result of
the timing of investments and redemptions. In addition, the effect of taxes on
any shareholder or partner will depend on such person's tax status, and the
results have not been reduced to reflect any income tax which may have been
payable.

1    The Russell Mid Cap Growth Index measures the performance of those
     companies among the 800 smallest companies in the Russell 1000 Index with
     higher than average price-to-book ratios and forecasted growth. The Russell
     1000 Index contains the top 1,000 securities of the Russell 3000 Index,
     which comprises the 3,000 largest U.S. securities as determined by total
     market capitalization. The Russell Mid Cap Growth Index is considered
     generally representative of the U.S. market for mid cap stocks. The average
     market capitalization is approximately $4 billion, the median market
     capitalization is approximately $2.5 billion and the largest company in the
     Index had an approximate market capitalization of $8.7 billion. This Index
     reflects the reinvestment of income dividends and capital gains
     distributions, if any, but does not reflect fees, brokerage commissions, or
     other expenses of investing. The Index was not available until 1986.
 
2    The CS First Boston Convertible Index is an unmanaged market weighted index
     representing the universe of convertible securities, whether they are
     convertible preferred stocks or convertible bonds. The Index reflects the
     reinvestment of income dividends and capital gains distributions, if any,
     but does not reflect fees, brokerage commissions or markups, or other
     expenses of investing.
 
3    The Salomon EPAC Extended Market Index ("EMI") is an unmanaged index that
     includes shares of approximately 2,800 companies in 22 countries excluding
     Canada and the United States. Companies included in the Index are smaller
     capitalization companies with available float market capitalizations
     greater than U.S. $100 million. Only issues that are legally and
     practically available to outside investors are included in the Index. Index
     returns reflect the reinvestment of income dividends and capital gains
     distributions, if any, but do not reflect fees, brokerage commissions, or
     other expenses of investing.
