                INVESTMENT OBJECTIVES AND PRINCIPAL STRATEGIES
- --------------------------------------------------------------------------------
 
All of the Galileo Fixed Income Funds are affected by changes in the economy, or
in securities and other markets. Additionally, changes in interest rates will
affect not only the current return on the Galileo Fixed Income Funds, but the
value of the capital investment will most likely fluctuate up or down. There is
also the possibility that investment decisions the Adviser makes will not
accomplish what they were designed to achieve or that companies in which the
Funds invest will have disappointing performance or not pay their debts.

</TABLE>

Under adverse market conditions, each Fund could invest some or all of its
assets in money market securities. Although the Funds would do this only when
seeking to avoid losses, it could have the effect of reducing the benefit from
any upswing in the market.

                                PRINCIPAL RISKS
- ------------------------------------------------------------------------------- 

Risk is the chance that you will lose money on your investment or that it will
not earn as much as you expect. In general, the greater the risk, the more money
your investment can earn for you -- and the more you can lose. Since shares of a
Fund represent an investment in securities with fluctuating market prices, the
value of fund shares will vary as the value of each Fund's portfolio securities
increases or decreases. Therefore, the value of an investment in a Fund could go
down as well as up. All investments are subject to:
    
 .  MARKET RISK      
 
   There is the possibility that the returns from the types of securities in
   which a Fund invests will underperform returns from the various general
   securities markets or different asset classes. Different types of securities
   tend to go through cycles of outperformance and underperformance in
   comparison to the general securities markets.

 .  SECURITIES SELECTION RISK
 
   There is the possibility that the specific securities held in a Fund's
   portfolio will underperform the other funds in the same asset class or
   benchmarks that are representative of the general performance of the asset
   class because of the portfolio manager's choice of securities.
 
Because the Galileo Funds described in this prospectus are fixed income funds,
each Fund may also be subject (in varying degrees) to the following additional
risks:
 
 .  CREDIT RISK
 
   There is the possibility that a Fund could lose money if an issuer is unable
   to meet its financial obligations such as the payment of principal and/or
   interest on an instrument, or goes bankrupt. The High Yield Bond Fund is
   subject to great credit risk because it invests in high yield bond funds,
   which are commonly referred to as "junk bonds." The Core Fixed Income Fund is
   subject to credit risk because it invests to some degree in below investment
   grade fixed income securities.
 
 .  INTEREST RATE RISK
 
   This the possibility that the value of the Fund's portfolio investments may
   fall since fixed income securities generally fall in value when interest
   rates rise. The longer the term of a fixed income instrument, the more
   sensitive it will be to fluctuations in value from interest rate changes.
   Changes in interest rates may have a significant effect on the Core Fixed
   Income, High Yield Bond, Total Return Mortgage-Backed Securities, and
   Mortgage-Backed Securities Funds, because each Fund may hold securities with
   long terms to maturity.
 
   In the case of mortgage-backed securities, rising interest rates tend to
   extend the term to maturity of the securities, making them even more
   susceptible to interest rate changes. When interest rates drop, not only can
   the value of fixed income securities drop, but the yield can drop,
   particularly where the yield on the fixed income securities is tied to
   changes in interest rates, such as adjustable mortgages. Also when interest
   rates drop, the holdings of mortgage-backed securities by the Core Fixed
   Income, Total Return Mortgage-Backed Securities and Mortgage-Backed
   Securities Funds can reduce returns if the owners of the underlying mortgages
   pay off their mortgages sooner than anticipated since the funds prepaid will
   have to be reinvested at the then lower prevailing rates. This is known as
   prepayment risk. When interest rates rise, the holdings of mortgage-backed
   securities by these Funds can reduce returns if the owners of the underlying
   mortgages pay off their mortgages later than anticipated. This is known as
   extension risk.

                                       4
<PAGE>
 
                                PRINCIPAL RISKS
- -------------------------------------------------------------------------------

 .  JUNK BONDS
 
   These bonds are speculative in nature. They are usually issued by companies
   without long track records of sales and earnings, or by those companies with
   questionable credit strength. These bonds are considered "below investment
   grade." The High Yield Bond Fund primarily invests in below investment grade
   corporate securities. The Core Fixed Income Fund may invest in debt
   instruments rated below investment grade.
 
 .  FOREIGN INVESTING RISK
     
   There is the likelihood that foreign investments may be riskier than U.S.
   investments because of a lack of political stability, foreign controls on
   investment and currency exchange rates, fluctuations in currency exchange
   rates, withholding taxes and lack of adequate company information. The Core
   Fixed Income and High Yield Bond Funds are subject to foreign investing risk
   because these Funds may invest a portion of their assets in foreign company
   securities. If they invest in "emerging markets," and they may, the risk is
   even more pronounced. In addition, because foreign securities generally are
   denominated and pay dividends or interest in foreign currencies, the Core
   Fixed Income and High Yield Bond Funds may hold various foreign currencies,
   the value of the net assets of these Funds as measured in U.S. dollars can be
   affected favorably or unfavorably by changes in exchange rates.      
 
 .  LIQUIDITY RISK
 
   There is the possibility that a Fund may lose money or be prevented from
   earning capital gains if it cannot sell a security at the time and price that
   is most beneficial to the Fund. Each Fund (except the Money Market Fund) is
   subject to liquidity risks because it invests in high yield bonds, mortgage-
   backed securities or foreign or emerging markets securities, which have all
   experienced periods of illiquidity.
    
 .  PREPAYMENT RISK      
    
 .  EXTENSION RISK      
     
Each Fund may be more susceptible to some of these risks than others, as noted
in the description of each Fund. A more detailed explanation of these risks is
presented under the "Risk Considerations" section at page 25.      

Your investment is not a bank deposit, and it is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency.
Although the Money Market Fund seeks to preserve the value of your investment at
$1.00 per share, it is possible to lose money by investing in the Fund. The
value of the other Galileo Fixed Income Funds will fluctuate in value.

                              PERFORMANCE SUMMARY
- -------------------------------------------------------------------------------
     
The two tables below show each Fund's annual returns and its long-term
performance with respect to its Institutional Class shares. The first table
shows you how the Fund's performance has varied from year to year. The second
compares the Fund's performance over time to that of a broad-based securities
market index. Both tables assume reinvestment of dividends and distributions.
The performance information includes the performance of predecessor limited
partnerships of each Fund, which were managed by an affiliate of TCW Funds
Management, INC., using the same investment strategy as the Funds. The
performance of the partnerships were calculated using performance standards
applicable to private investment partnerships, which take into account all
elements of total return and reflect the deduction of all fees and expenses of
operation, except for the Money Market and Total Return Mortgage-Backed
Securities Funds. The predecessor limited partnerships were not registered under
the Investment Company Act of 1940 ("1940 Act") and, therefore, were not subject
to certain investment restrictions imposed by the 1940 Act. If the limited
partnerships had been registered under the 1940 Act and Subchapter M of the
Internal Revenue Code of 1986 as amended, their performance might have been
adversely affected. As with all mutual funds, past performance is not a
prediction of future results.

EXPENSE EXAMPLE

This Example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other mutual funds.
    
This example shows what you could pay in expenses over time. It uses the same
hypothetical conditions other funds use in their prospectuses: $10,000 Initial
Investment, 5% total return each year and no changes in expenses. The figures
shown would be the same whether or not you sold your shares at the end of a
period. Because actual return and expenses will be higher or lower, the Example
is for comparison purposes only.

INVESTMENT OBJECTIVES/APPROACH
- ------------------------------

CONCEPTS TO UNDERSTAND
- ----------------------

Maturity is the date on which the principal amount of a note, draft, acceptance,
bond, or other debt instrument becomes due and payable.

The Fund seeks current income, preservation of capital and liquidity. To pursue
these goals, it invests in high credit quality, short-term money market
securities. The Fund also seeks to maintain a constant net asset value of $1.00
per share. To pursue this goal, the Fund invests in money market instruments
that have remaining maturities of 397 days or less (and an average portfolio
maturity of 90 days or less on a dollar-weighted basis).

If the Fund's board believes that any deviation from a $1.00 amortized cost
price per share may result in material dilution or other unfair results to new
or existing shareholders, it will take steps to eliminate or reduce these
consequences. These steps include:

 .  selling portfolio securities prior to maturity

 .  shortening the average maturity of the portfolio

 .  withholding or reducing dividends

 .  redeeming shares in kind

 .  utilizing a net asset value per share determined by using available market
   quotations

MAIN RISKS
- ----------

This portfolio generally has the least investment risk of the Galileo Funds
because it invests in securities that have high credit ratings.

The two primary risks affecting this Fund are "credit risk" and "interest rate
risk." CREDIT RISK refers to the likelihood that the Fund could lose money if a
money market issuer is unable to meet its financial obligations, such as the
payment of principal and/or interest on an investment, or goes bankrupt. This
Fund invests primarily in securities that have limited susceptibility to this
risk. INTEREST RATE RISK refers to the possibility that the value of the Fund's
portfolio investment may fall since fixed income securities generally fall in
value when interest rates rise. Short-term money market instruments generally
are affected less by changes in interest rates than fixed income securities with
longer terms to maturity.

The Fund seeks to earn additional income by making loans of its portfolio
securities to brokers, dealers and other financial institutions. The loans will
be secured at all times by cash and liquid high-grade debt obligations. As with
any extension of credit, there are risks of delay in recovery and in some cases
even loss of rights in the collateral should the borrower fail financially.

INVESTMENT OBJECTIVES/APPROACH
- ------------------------------

CONCEPTS TO UNDERSTAND
- ----------------------

Duration is often used to measure the potential volatility of a bond's price: 
bonds with longer durations are more sensitive to changes in interest rates, 
making them more volatile than bonds with shorter durations. Bonds with fixed 
maturities have a readily determinable duration. Bonds with uncertain payment 
schedules, such as mortgage-backed securities, which can be prepaid, have 
durations which may vary or lengthen in certain interest rate environments, 
making their values even more volatile than they were when acquired.
    
The Fund seeks to provide maximum current income and achieve above average total
return consistent with prudent investment management over a full market cycle.
To pursue this goal, it invests (except when maintaining a temporary defensive
position) at least 65% of  the value of its total assets in fixed income
securities rated A or higher by Moody's and S&P. These securities include U.S.
Government obligations, bonds, notes, debentures, mortgage-backed securities,
asset-backed securities, foreign securities (government and corporate) and other
securities bearing fixed or variable interest rates of any maturity.      

In managing the Fund's investments, the Adviser uses a controlled risk approach.
The techniques of this approach attempt to control the principal risk components
of the fixed income markets. These components include:

 .  security selection within a given sector

 .  relative performance of the various market sectors

 .  the shape of the yield curve

 .  fluctuations in the overall level of interest rates

The Adviser also utilizes active asset allocation in managing the Fund's
investments and monitors the duration of the Fund's portfolio securities to
mitigate the Fund's exposure to interest rate risk.

MARK L. ATTANASIO, PHILIP A. BARACH AND JEFFREY E. GUNDLACH ARE THE FUND'S
PORTFOLIO MANAGERS.

MAIN RISKS
- ----------

The primary risks affecting this Fund are "credit risk," "interest rate risk"
(including "extension risk" and "prepayment risk"), "foreign investing risk" and
"liquidity risk."

CREDIT RISK refers to the likelihood that the Fund could lose money if an issuer
is unable to meet its financial obligations, such as the payment of principal
and/or interest on an instrument, or goes bankrupt. This Fund invests primarily
in high credit quality securities that have limited susceptibility to this risk.
A portion of the Fund's assets, however, will be invested in low credit quality
securities, which may make the Fund more susceptible to credit risk. Debt
securities that are rated below investment grade are considered to be
speculative. Those securities rated below investment grade are also commonly
known as "junk" bonds. This is especially true during periods of economic
uncertainty or during economic downturns. INTEREST RATE RISK refers to the
possibility that the value of the Fund's portfolio investments may fall since
fixed income securities generally fall in value when interest rates rise. The
longer the term of a fixed income instrument, the more sensitive it will be to
fluctuations in value from interest rate changes. Changes in interest rates may
have a significant effect on this Fund, because it may hold securities with long
terms to maturity and mortgage-backed securities, including collateralized
mortgage obligations and stripped mortgage securities. Its holding of mortgage-
backed securities can reduce returns if the owners of the underlying mortgages
pay off their mortgage sooner than anticipated when interest rates go down.
Because this Fund invests in mortgage-backed securities, it may be subject to
extension risk and prepayment risk, which are both a type of interest rate risk.
EXTENSION RISK refers to the possibility that rising interest rates may cause
owners of the underlying mortgages to pay off their mortgages at a slower than
expected rate. This particular risk may effectively change a security which was
considered short or intermediate term into a long-term security. Long-term
securities generally drop in value more dramatically in response to rising
interest rates than short or intermediate-term securities. PREPAYMENT RISK
refers to the possibility that falling interest rates may cause owners of the
underlying mortgages to pay off their mortgages at a faster than expected rate.
This tends to reduce returns since the funds prepaid will have to be reinvested
at the then lower prevailing rates. Because the Fund may invest a portion of its
assets in foreign company securities, it may be subject to FOREIGN INVESTING
RISKS.

                                       14
<PAGE>
 
Foreign investing risk refers to the likelihood that foreign investments may be
riskier than U.S. investments because of many factors, some of which include:

 .  a lack of political or economic stability

 .  foreign controls on investment and changes in currency exchange rates

 .  withholding taxes

 .  a lack of adequate company information

The risks of foreign investing are even more pronounced if the Fund invests in
emerging markets. In addition, securities traded only through foreign markets
may be more volatile and are often harder to sell. Volatility is a way to
measure the changes in the price of a single security or an entire portfolio.
Large and frequent price changes indicate higher volatility, which generally
indicates that there is a greater chance you could lose money over the short
term. The Fund is also subject to foreign currency risk. Because foreign
securities are generally denominated and pay dividends or interest in foreign
currencies, the value of the net assets of the Fund as measured in United States
dollars will be affected favorably or unfavorably by changes in exchange rates.
LIQUIDITY RISK refers to the possibility that the Fund may lose money or be
prevented from earning capital gains if it cannot sell a security at the time
and price that is most beneficial to the Fund. Because the Fund invests in below
investment grade fixed income securities and foreign securities, it is more
susceptible to liquidity risks than funds that invest in higher quality
investments or do not invest in foreign securities.

The Fund may invest some assets in options, futures and foreign currency futures
and forward contracts. These practices are used primarily to hedge the Fund's
portfolio but may also be used to increase returns; however, such practices
sometimes may reduce returns or increase volatility.

The Fund seeks to earn additional income by making loans of its portfolio
securities to brokers, dealers and other financial institutions. The loans will
be secured at all times by cash and liquid high-grade debt obligations. As with
any extension of credit, there are risks of delay in recovery and in some cases
even loss of rights in the collateral should the borrower fail financially.
    
The Fund may engage in active portfolio management which may result in increased
Fund transaction expenses and have tax consequences, such as increased realized 
gains, for investors.

CONCEPTS TO UNDERSTAND

DURATION is often used to measure the potential volatility of a bond's price: 
bonds with longer durations are more sensitive to changes in interest rates, 
making them more volatile than bonds with shorter durations. Bonds with fixed 
maturities have a readily determinable duration. Bonds with uncertain payment 
schedules, such as mortgage-backed securities which can be prepaid, have 
durations which may vary or lengthen in certain interest rate environments, 
making their value even more volatile than they were when acquired.
    
WEIGHTED AVERAGE DURATION is the average duration of the securities in the 
portfolio weighted by market value.      

WEIGHTED AVERAGE RESET FREQUENCY is the average time to the next coupon reset 
date of the floating rate securities in the portfolio weighted by market value.

The Fund seeks to maximize current income. To pursue this goal, the Fund invests
primarily in short-term mortgage-backed securities guaranteed by, or secured by
collateral that is guaranteed by, the United States Government, its agencies,
instrumentalities or its sponsored corporations (collectively, the "Federal
Agencies"), and in privately issued mortgage-backed securities rated Aa or
higher by Moody's or AA or higher by S&P.
    
The Fund will invest (except when maintaining a temporary defensive position) at
least 65% of the value of its total assets in mortgage-backed securities which
are guaranteed by, or secured by collateral which is guaranteed by, Federal
Agencies.  In managing the Fund's investments, the Adviser seeks to construct a
portfolio with a weighted average duration for fixed rate securities and a
weighted average reset frequency for floating rate securities of no more than
two years.

The primary risks affecting this Fund are "credit risk," "interest rate risk"
(including "extension risk" and "prepayment risk"), and "liquidity risk."

CREDIT RISK refers to the likelihood that the Fund could lose money if an issuer
is unable to meet its financial obligations, such as the payment of principal
and/or interest on an instrument, or goes bankrupt. The Fund may invest a
portion of its assets in mortgage-backed securities which are not guaranteed by
the U.S. Government, which may make the Fund subject to substantial credit risk.
This is especially true during periods of economic uncertainty or during
economic downturns. INTEREST RATE RISK refers to the possibility that the value
of the Fund's portfolio investments may fall since fixed income securities
generally fall in value when interest rates rise. The longer the term of a fixed
income instrument, the more sensitive it will be to fluctuations in value from
interest rate changes. Changes in interest rates may have a significant effect
on this Fund, because it may hold securities with long terms to maturity and
mortgage-backed securities, including collateralized mortgage obligations, and
stripped mortgage securities. Its holdings of mortgage-backed securities can
reduce returns if the owners of the underlying mortgages pay off their mortgages
sooner than anticipated when interest rates go down. Because this Fund invests

prepayment risk, which are both a type of interest rate risk. EXTENSION RISK
refers to the possibility that rising interest rates may cause owners of the

This particular risk may effectively change a security which was considered
short or intermediate term into a long-term security. Long-term securities
generally drop in value more dramatically in response to rising interest rates
than short or intermediate-term securities. PREPAYMENT RISK refers to the
possibility that falling interest rates may cause owners of the underlying
mortgages to pay off their mortgages at a faster than expected rate. This tends
to reduce returns since the funds prepaid will have to be reinvested at the then
lower prevailing rates. LIQUIDITY RISK refers to the possibility that the Fund
may lose money or be prevented from earning capital gains if it cannot sell a
security at the time and price that is most beneficial to the Fund. Because
mortgage-backed securities may be less liquid than other securities, the Fund
may be more susceptible to liquidity risks than funds that invest in other
securities.

The Fund may invest some assets in inverse floaters and interest-only and
principal-only securities, which are sometimes referred to as derivatives. These
practices may reduce returns or increase volatility and may be very sensitive to
changes in interest rates.    

The Fund seeks to earn additional income by making loans of its portfolio
securities to brokers, dealers and other financial institutions. The loans will
be secured at all times by cash and liquid high-grade debt obligations. As with
any extension of credit, there are risks of delay in recovery and in some cases
even loss of rights in the collateral should the borrower fail financially.

Fund transaction expenses and have tax consequences, such as increased realized 
gains, for investors.

           TCW GALILEO TOTAL RETURN MORTGAGE-BACKED SECURITIES FUND

INVESTMENT OBJECTIVES/APPROACH
- ------------------------------

CONCEPTS TO UNDERSTAND
- ----------------------

DURATION is often used to measure the potential volatility of a bond's price: 
bonds with longer durations are more sensitive to changes in interest rates, 
making them more volatile than bonds with shorter durations. Bonds with fixed 
maturities have a readily determinable duration. Bonds with uncertain payment 
schedules, such as mortgage-backed securities which can be prepaid, have 
durations which may vary or lengthen in certain interest rate environments, 
marking their value even more volatile than they were when acquired.
    
WEIGHTED AVERAGE DURATION is the average duration of the securities in the 
portfolio weighted by market value.      

WEIGHTED AVERAGE RESET FREQUENCY is the average time to the next coupon reset 
date of the floating rate securities in the portfolio weighted by market value.

The Fund seeks to maximize current income and achieve above average total return
consistent with prudent investment management over a full market cycle. To
pursue these goals, the Fund invests primarily in mortgage-backed securities of
any maturity or type guaranteed by, or secured by collateral that is guaranteed
by, the United States Government, its agencies, instrumentalities or its
sponsored corporations (collectively, the "Federal Agencies"), and in privately
issued mortgage-backed securities rated Aa or higher by Moody's or AA or higher
by S&P.
    
The Fund will invest (except when maintaining a temporary defensive position) at
least 65% of the value of its total assets in mortgage-backed securities which
are guaranteed by, or secured by collateral which is guaranteed by Federal
Agencies.  In managing the Fund's investments, the Adviser seeks to construct a
portfolio with a weighted average duration for fixed rate securities and a
weighted average reset frequency for floating rate securities of no more than
eight years.      

PHILIP A. BARACH, JEFFREY E. GUNDLACH AND FREDERICK H. HORTON ARE THE FUND'S
PORTFOLIO MANAGERS.

MAIN RISKS
- ----------

The primary risks affecting this Fund are "credit risk," "interest rate risk"
(including "extension risk" and "prepayment risk"), and "liquidity risk."

CREDIT RISK refers to the likelihood that the Fund could lose money if an issuer
is unable to meet its financial obligations, such as the payment of principal
and/or interest on an instrument, or goes bankrupt. The Fund may invest a
portion of its assets in mortgage-backed securities which are not guaranteed by
the U.S. Government, which may make the Fund subject to substantial credit risk.
This is especially true during periods of economic uncertainty or during
economic downturns. INTEREST RATE RISK refers to the possibility that the value
of the Fund's portfolio investments may fall since fixed income securities
generally fall in value when interest rates rise. The longer the term of a fixed
income instrument, the more sensitive it will be to fluctuations in value from
interest rate changes. Changes in interest rates may have a significant effect
on this Fund, because it may hold securities with long terms to maturity and
mortgage-backed securities, including collateralized mortgage obligations, and
stripped mortgage securities. Because this Fund invests in mortgage-backed
securities, it may be subject to extension risk and prepayment risk, which are
both a type of interest rate risk. EXTENSION RISK is the possibility that rising
interest rates may cause owners of the underlying mortgages to pay off their
mortgages at a slower than expected rate. This particular risk may effectively
change a security which was considered short or intermediate term into a long-
term security. Long-term securities generally drop in value more dramatically in
response to rising interest rates than short or intermediate-term securities.
PREPAYMENT RISK refers to the possibility that falling interest rates may cause
owners of the underlying mortgages to pay off their mortgages at a faster than
expected rate. This tends to reduce returns since the funds prepaid will have to
be reinvested at the then lower prevailing rates. LIQUIDITY RISK refers to the
possibility that the Fund may lose money or be prevented from earning capital
gains if it cannot sell a security at the time and price that is most beneficial
to the Fund. Because mortgage-backed securities may be less liquid than other
securities, the Fund may be more susceptible to liquidity risks than funds that
invest in other securities.

The Fund may invest some assets in inverse floaters and interest-only and
principal-only securities, which are sometimes referred to as

                                       20
<PAGE>

     
derivatives. These practices may be used to increase returns; however, such
practices sometimes may reduce returns or increase volatility and may be very 
sensitive to changes in interest rates.      

The Fund seeks to earn additional income by making loans of its portfolio
securities to brokers, dealers and other financial institutions. The loans will
be secured at all times by cash and liquid high-grade debt obligations. As with
any extension of credit, there are risks of delay in recovery and in some cases
even loss of rights in the collateral should the borrower fail financially.
    
The Fund may engage in active portfolio management which may result in increased
Fund transaction expenses and have tax consequences such as increased realized 
gains for investors.

                       TCW GALILEO HIGH YIELD BOND FUND

INVESTMENT OBJECTIVES/APPROACH
- ------------------------------

CONCEPTS TO UNDERSTAND
- ----------------------

JUNK BONDS are bonds that have a credit rating of BB or lower by rating agencies
such as Moody's Investors Service, Inc. and Standard & Poor's Corporation. These
bonds are often issued by companies without long track records of sales and 
earnings, or by those companies with questionable credit strength. In the event 
of a prepayment problem by the issuer of these bonds, they will only be paid if 
there is anything left after the payment of senior debt, such as bank loans and 
investment grade bonds. 

Junk bonds are considered to be mostly speculative in nature. This gives the 
Fund more credit risk than Galileo's other fixed income funds, but also give it 
the potential for higher returns.
    
The Fund seeks to maximize income and achieve above average total return
consistent with reasonable risk over a full market cycle. To pursue this goal,
it invests (except when maintaining a temporary defensive position) at least 65%
of the value of its total assets in high yield/below investment grade bonds,
commonly known as "junk" bonds.  It also invests in other high yield fixed
income securities, including convertible and nonconvertible debt securities. 
    
In managing the Fund's investments, the Adviser places emphasis on securities at
the lower-risk end of the high yield bond/below investment grade spectrum. These
securities are issued by companies that the Adviser believes have stable to
improving business prospects. The Adviser's investment approach also emphasizes
consistent and high current income. It attempts to reduce the Fund's investment
risk through diversification and by analysis of:

 .  each issuer

 .  each issuer's ability to make timely payments of principal and interest

 .  broad economic trends and corporate developments

MARK L. ATTANASIO, MARK D. SENKPIEL, AND MELISSA V. WEILER ARE THE FUND'S
PORTFOLIO MANAGERS.

MAIN RISKS
- ----------

The primary risks affecting this Fund are "credit risk," "interest rate risk,"
"liquidity risk" and, to a lesser extent, "foreign investing risk."

CREDIT RISK refers to the likelihood that the Fund could lose money if an issuer
is unable to meet its financial obligations, such as the payment of principal
and/or interest on an instrument, or goes bankrupt. This Fund is subject to high
credit risk, because it invests primarily in high yield/below investment grade
bonds. Debt securities that are rated below investment grade are considered to
be speculative. Those securities rated below investment grade are also commonly
known as "junk" bonds. This is especially true during periods of economic
uncertainty or during economic downturns. INTEREST RATE RISK refers to the
possibility that the value of the Fund's portfolio investments may fall since
fixed income securities generally fall in value when interest rates rise. The
longer the term of a fixed income instrument, the more sensitive it will be to
fluctuations in value from interest rate changes. Changes in interest rates may
have a significant effect on this Fund, because it may hold securities with long
terms to maturity. LIQUIDITY RISK refers to the possibility that the Fund may
lose money or be prevented from earning capital gains if it cannot sell a
security at the time and price that is most beneficial to the Fund. Because high
yield bonds may be less liquid than higher quality securities, the Fund may be
more susceptible to liquidity risk than funds that invest in higher quality
investments. A security whose credit rating has been lowered may be particularly
difficult to sell. Because the Fund may invest a portion of its assets in
foreign company securities, it may be subject to FOREIGN INVESTING RISK. Foreign
investing risk refers to the likelihood that foreign investments may be riskier
than U.S. investments because of many factors, some of which include:

 .  a lack of political or economic stability

 .  foreign controls on investment and currency exchange rates

 .  withholding taxes

 .  a lack of adequate company information

The risks of foreign investing are even more pronounced if the Fund invests in
emerging markets. In addition, securities traded only through foreign markets
may be more volatile and are often harder to sell. Volatility is a way to
measure the changes in the price of a single security or an entire portfolio.
Large and frequent price changes indicate higher volatility, which generally
indicate that there is a greater chance

                                       23
<PAGE>
 
you could lose money over the short term. The Fund is also subject to foreign
currency risk. Because foreign securities are generally denominated and pay
dividends or interest in foreign currencies, the value of the net assets of the
Fund as measured in the United States dollars will be affected favorably or
unfavorably by changes in exchange rates.

The Fund seeks to earn additional income by making loans of its portfolio
securities to brokers, dealers and other financial institutions. The loans will
be secured at all times by cash and liquid high-grade debt obligations. As with
any extension of credit, there are risks of delay in recovery and in some cases
even loss of rights in the collateral should the borrower fail financially.
    
The Fund may engage in active portfolio management which may result in increased
Fund transaction expenses and have tax consequences such as increased realized 
gains for investors.

RISK CONSIDERATIONS
- -------------------

GENERAL INVESTMENT RISK
- -----------------------

Since shares of a Fund represent an investment in securities with fluctuating 
market prices, the value of Fund shares will vary as the value of each Fund's 
portfolio securities increases or decreases. Therefore, the value of an 
investment in a Fund could go down as well as up. This is also true for funds 
that invest primarily in fixed income securities. High credit quality 
investments also react in value to interest rate changes.

Please consider the following risks before investing in a Fund.

Various market risks can affect the price or liquidity of an issuer's
securities. Adverse events occurring with respect to an issuer's performance or
financial position can depress the value of the issuer's securities. The
liquidity in a market for a particular security will affect its value and may be
affected by factors relating to the issuer and the depth of the market for that
security. Other market risks that can affect value include a market's current
attitudes about type of security, market reactions to political or economic
events, and tax and regulatory effects (including lack of adequate regulations
for a market or particular type of instrument). Market restrictions on trading
volume can also affect price and liquidity.

Prices of most securities tend to be more volatile in the short-term. Therefore
an investor who trades frequently or redeems in the short-term is more likely to
incur loss than an investor who holds investments for the longer term. The fewer
the number of issuers in which a Fund invests, the greater the potential
volatility of its portfolio. A security that is leveraged, whether explicitly or
implicitly, will also tend to be more volatile in that both gains and losses are
intensified by the magnifying effects of leverage. Certain instruments (such as
inverse floaters and interest-only securities) behave similarly to leveraged
instruments.
    
The Adviser may temporarily invest up to 100% of the Fund's assets in high
quality, short-term money market instruments if it believes adverse economic or
market conditions, such as excessive volatility or sharp market declines,
justify taking a defensive investment posture. If the Fund attempts to limit
investment risk by temporarily taking a defensive investment position, it may be
unable to pursue its investment objective during that time, and it may miss out
on some or all of an upswing in the securities markets.     

                                       25
<PAGE>
 
RISK CONSIDERATIONS
- -------------------

FIXED INCOME SECURITIES
- -----------------------

Fixed income securities are subject to various risks. The two primary (but not
exclusive) risks affecting fixed income instruments are "credit risk" and
"interest rate risk." These risks can affect a security's price volatility to
varying degrees, depending upon the nature of the instrument. In addition, the
depth and liquidity of the market for an individual or class of fixed income
security can also affect its price and, hence, the market value of a Fund.

"CREDIT RISK" refers to the likelihood that an issuer will default in the
payment of principal and/or interest on an instrument. Financial strength and
solvency of an issuer are the primary factors influencing credit risk. In
addition, lack of or inadequacy of collateral or credit enhancements for a fixed
income security may affect its credit risk. Credit risk of a security may change
over its life and securities which are rated by rating agencies are often
reviewed and may be subject to downgrades.

The High Yield Bond portfolio consists primarily of below investment grade
corporate securities that are commonly known as junk bonds. In addition, the
Core Fixed Income Fund may invest in debt instruments rated below investment
grade. Generally, lower-rated debt securities provide a higher yield than higher
rated debt securities of similar maturity but are subject to greater credit risk
than higher rated securities of similar maturity. These securities are regarded
as predominantly speculative with respect to the issuer's continuing ability to
meet principal and interest payments. Because investment in lower quality
securities involves greater investment risk, achievement of a Fund's investment
objective will be more dependent

                                       26
<PAGE>
 
on the Adviser's analysis than would be the case if the Fund were investing in
higher quality bonds. In addition, lower quality securities may be more
susceptible to real or perceived adverse economic and individual corporate
developments than would investment grade bonds. Moreover, the secondary trading
market for lower quality securities may be less liquid than the market for
investment grade bonds. This potential lack of liquidity may make it more
difficult for the Adviser to value accurately certain portfolio securities.

"INTEREST RATE RISK" refers to the change in value of debt instruments
associated with changes in interest rates. Interest rate changes may affect the
value of a fixed income security directly (especially in the case of fixed rate
securities) and indirectly (especially in the case of adjustable rate
securities). In general, rises in interest rates will negatively impact the
value of fixed rate securities and falling interest rates will have a positive
effect on value. The degree to which a security's price will change as a result
of changes in interest rates is measured by its "duration." For example, the
price of a bond with a 5 year duration would be expected under normal market
conditions to decrease 5% for every 1% increase in interest rates. Generally,
securities with longer maturities have a greater duration and thus are subject
to greater price volatility from changes in interest rates. Adjustable rate
instruments also react to interest rate changes in a similar manner although
generally to a lesser degree (depending, however, on the characteristics of the
reset terms, including the index chosen, frequency of reset and reset caps or
floors, among other things).

                                       27

RISK CONSIDERATIONS
- -------------------

FOREIGN INVESTING
- -----------------

Investment in foreign securities involves special risks in addition to the usual
risks inherent in domestic investments. These include: political or economic
instability; the unpredictability of international trade patterns; the
possibility of foreign governmental actions such as expropriation,
nationalization or confiscatory taxation; the imposition or modification of
currency exchange or foreign investment controls; the imposition of withholding
taxes on dividends, interest and gains; price volatility; and fluctuations in
currency exchange rates. These risks are more pronounced in emerging market
countries.

As compared to United States companies, foreign issuers generally disclose less
financial and other information publicly and are subject to less stringent and
less uniform accounting, auditing and financial reporting standards. Foreign
countries typically impose less thorough regulations on brokers, dealers, stock
exchanges, insiders and listed companies than does the United States, and
foreign securities markets may be less liquid and more volatile than domestic
markets. Investment in foreign securities involves higher costs than investment
in U.S. securities, including higher transaction and custody costs as well as
the imposition of additional taxes by foreign governments. In addition, security
trading practices abroad may offer less protection to investors such as the
Funds. Settlement of transactions in some foreign markets may be delayed or may
be less frequent than in the U.S., which could affect the liquidity of each
Fund's portfolio. Also, it may be more difficult to obtain and enforce legal
judgments against foreign corporate issuers than against

                                       28
<PAGE>
 
domestic issuers and it may be impossible to obtain and enforce judgments
against foreign governmental issuers.
    
Because foreign securities generally are denominated and pay dividends or
interest in foreign currencies, and some of the Funds may hold various foreign
currencies from time to time, the value of the net assets of those Funds as
measured in United States dollars can be affected favorably or unfavorably by
changes in exchange rates. Generally, currency exchange transactions will be
conducted on a spot (i.e., cash) basis at the spot rate prevailing in the
                     ----
currency exchange market. The cost of currency exchange transactions will
generally be the difference between the bid and offer spot rate of the currency
being purchased or sold. In order to protect against uncertainty in the level of
future foreign currency exchange rates, the Core Fixed Income Fund is authorized
to enter into certain foreign currency futures and forward contracts. However,
it is not obligated to do so and, depending on the availability and cost of
these devices, the Fund may be unable to use foreign currency futures and
forward contracts to protect against currency uncertainty. Please see the
Statement of Additional Information for further information.      

With respect to the Core Fixed Income Fund, the forward currency market for the
purchase or sale of U.S. dollars in some countries is not highly developed, and
in certain countries, there may be no such market. If a devaluation of a
currency is generally anticipated, the Fund may not be able to contract to sell
the currency at an exchange rate more advantageous than that which would prevail
after the anticipated amount of devaluation, particularly as regards forward
contracts for local currencies in view of the relatively small, inactive or even
non-existent market for these contracts. In the event the Funds hold securities
denominated in a currency that suffers a devaluation, the Funds' net asset
values will suffer corresponding reductions. In this regard, in December 1994,
the Mexican government determined to allow the Mexican peso to trade freely
against the U.S. dollar rather than within a controlled band, which resulted in
a significant devaluation of the Mexican peso against the dollar. Further, in
July 1997, the Thai and Philippine governments allowed the baht and peso,
respectively, to trade freely against the U.S. dollar resulting in a sharp
devaluation of both currencies, and in 1998 Russia did the same, causing a sharp
devaluation of the ruble.

RISK CONSIDERATIONS
- -------------------

MORTGAGE-BACKED SECURITIES
- --------------------------

CREDIT AND MARKET RISKS OF MORTGAGE-BACKED SECURITIES. The investments by Core
Fixed Income in fixed rate and floating rate mortgage-backed securities will
entail normal credit risks (i.e., the risk of non-payment of interest and
                            ----
principal) and market risks (i.e., the risk that interest rates and other
                             ----
factors will cause the value of the instrument to decline). Many issuers or
servicers of mortgage-backed securities guarantee timely payment of interest and
principal on the securities, whether or not payments are made when due on the
underlying mortgages. This kind of guarantee generally increases the quality of
a security, but does not mean that the security's market value and yield will
not change. Like bond investments, the value of fixed rate mortgage-backed
securities will tend to rise when interest rates fall, and fall when rates rise.
Floating rate mortgage-backed securities will generally tend to have minimal
changes in price when interest rates rise or fall, but their current yield will
be affected. The value of all mortgage-backed securities may also change because
of changes in the market's perception of the creditworthiness of the
organization that issued or guarantees them. In addition, the mortgage-backed
securities market in general may be adversely affected by changes in
governmental legislation or regulation. Fluctuations in the market value of
mortgage-backed securities after their acquisition usually do not affect cash
income from these securities but are reflected in Fund's net asset value.
Factors that could affect the value of a mortgage-backed security include, among
other things, the types and amounts of insurance which a mortgage carries, the
amount of time the mortgage loan has been outstanding, the loan-to-value ratio
of each mortgage and the amount of overcollateralization of a mortgage pool.

                                       30
<PAGE>
 
LIQUIDITY RISK OF MORTGAGE-BACKED SECURITIES. The liquidity of mortgage-backed
securities varies by type of security; at certain times a Fund may encounter
difficulty in disposing of investments. Because mortgage-backed securities may
be less liquid than other securities, a Fund may be more susceptible to
liquidity risks than funds that invest in other securities. In the past, in
stressed markets, certain types of mortgage-backed securities, such as inverse
floaters, and interest-only securities, suffered periods of illiquidity if
disfavored by the market.

PREPAYMENT, EXTENSION AND REDEMPTION RISKS OF MORTGAGE-BACKED SECURITIES.
Mortgage-backed securities reflect an interest in monthly payments made by the
borrowers who receive the underlying mortgage loans. Although the underlying
mortgage loans are for specified periods of time, such as 20 or 30 years, the
borrowers can, and typically do, pay them off sooner. When that happens, the
mortgage-backed security which represents an interest in the underlying mortgage
loan will be prepaid. A borrower is more likely to prepay a mortgage which bears
a relatively high rate of interest. This means that in times of declining
interest rates, a portion of the Fund's higher yielding securities are likely to
be redeemed and the Fund will probably be unable to replace them with securities
having as great a yield. Prepayments can result in lower yields to shareholders.
The increased likelihood of prepayment when interest rates decline also limits
market price appreciation of mortgage-backed securities. This is known as
prepayment risk. Mortgage-backed securities are also subject to extension risk.
Extension risk is the possibility that rising interest rates may cause
prepayments to occur at a slower than expected rate. This particular risk may
effectively change a security which was considered short or intermediate term
into a long-term security. Long-term securities generally fluctuate more widely
in response to changes in interest rates than short or intermediate-term
securities. In addition, a mortgage-backed security may be subject to redemption
at the option of the issuer. If a mortgage-backed security held by a Fund is
called for redemption, the Fund will be required to permit the issuer to redeem
or "pay-off" the security, which could have an adverse effect on the Fund's
ability to achieve its investment objective.

COLLATERALIZED MORTGAGE OBLIGATIONS. There are certain risks associated
specifically with collateralized mortgage obligations ("CMOs.") CMOs are debt
obligations collateralized by mortgage loans or mortgage pass-through
securities. The average life of CMOs is determined using mathematical models
that incorporate prepayment assumptions and other 

                                       31
<PAGE>
 
factors that involve estimates of future economic and market conditions. These
estimates may vary from actual future results, particularly during periods of
extreme market volatility. Further, under certain market conditions, such as
those that occurred in 1994, the average weighted life of certain CMOs may not
accurately reflect the price volatility of such securities. For example, in
periods of supply and demand imbalances in the market for such securities and/or
in periods of sharp interest rate movements, the prices of CMOs may fluctuate to
a greater extent than would be expected from interest rate movements alone. CMOs
issued by private entities are not obligations issued or guaranteed by the
United States Government, its agencies or instrumentalities and are not
guaranteed by any government agency, although the securities underlying a CMO
may be subject to a guarantee. Therefore, if the collateral securing the CMO, as
well as any third party credit support or guarantees, is insufficient to make
payment, the holder could sustain a loss.
    
STRIPPED MORTGAGE SECURITIES. Part of the investment strategy of the Core Fixed
Income, Total Return Mortgage-Backed Securities and Mortgage-Backed Securities
Funds involves interest-only Stripped Mortgage Securities. These investments may
be highly sensitive to changes in interest and tend to be less
liquid than other CMOs. In addition, prepayments of the underlying mortgages 
likely would lower the Funds' returns from stripped securities they hold.      

INVERSE FLOATERS. Total Return Mortgage-Backed and Mortgage-Backed Securities
Funds invest in inverse floaters, a class of CMOs with a coupon rate that resets
in the opposite direction from the market rate of interest to which it is
indexed such as London Interbank Offered Rate (LIBOR) or COFI. Any rise in the
index rate (as a consequence of an increase in interest rates) causes a drop in
the coupon rate of an inverse floater while any drop in the index rate causes an
increase in the coupon of an inverse floater. An inverse floater may behave like
a security that is leveraged since its interest rate usually varies by a
magnitude much greater than the magnitude of the change in the index rate of
interest. The "leverage-like" characteristics inherent in inverse floaters are
associated with greater volatility in their market prices.

ADJUSTABLE RATE MORTGAGES. ARMs contain maximum and minimum rates beyond which
the mortgage interest rate may not vary over the lifetime of the security. In
addition, many ARMs provide for additional limitations on the maximum amount by
which the mortgage interest rate may adjust for any single adjustment period.
Alternatively, certain 

                                       32
<PAGE>
 
ARMs contain limitations on changes in the required monthly payment. In the
event that a monthly payment is not sufficient to pay the interest accruing on
an ARM, any excess interest is added to the principal balance of the mortgage
loan, which is repaid through future monthly payments. If the monthly payment
for such an instrument exceeds the sum of the interest accrued at the applicable
mortgage interest rate and the principal payment required at such point to
amortize the outstanding principal balance over the remaining term of the loan,
the excess is utilized to reduce the then-outstanding principal balance of the
ARM.

ASSET-BACKED SECURITIES. Certain asset-backed securities do not have the benefit
of the same security interest in the related collateral as do mortgage-backed
securities; nor are they provided government guarantees of repayment. Credit
card receivables are generally unsecured, and the debtors are entitled to the
protection of a number of state and federal consumer credit laws, many of which
give such debtors the right to set off certain amounts owed on the credit cards,
thereby reducing the balance due. In addition, some issuers of automobile
receivables permit the servicers to retain possession of the underlying
obligations. If the servicer were to sell these obligations to another party,
there is a risk that the purchaser would acquire an interest superior to that of
the holders of the related automobile receivables.

RISK CONSIDERATIONS
- -------------------

YEAR 2000
- ---------
    
The investment advisory and management services provided by the Adviser and the
services provided to shareholders by the Transfer Agent depend on the smooth
functioning of their computer systems. Many computer software systems in use
today cannot recognize the year 2000, but revert to 1900 or some other date, due
to the manner in which dates were encoded and calculated. That failure could
have a negative impact on the handling of securities trades, pricing and account
services. The Adviser and the Transfer Agent have been actively working on
necessary changes to their own computer systems to prepare for the year 2000 and
expect that their systems will be adapted for year 2000 compliance before that
date, but there can be no assurance that they will be successful, or that
interaction with other non-complying computer systems will not impair their
services at that time. The Adviser has been, and is currently in contact with,
each of its External Service Providers to evaluate their readiness for the year
2000. The Adviser has requested each of its External Service Providers to either
(i) prepare a description of its process for identifying date sensitive areas,
its approach for implementing changes, its testing methodology, along with its
timetable for completion, or (ii) certify as to its year 2000 compliance.      

In addition, it is possible that the markets for securities in which the Funds
invest may be negatively affected by computer failures throughout the financial
services industry commencing January 1, 2000. Improperly functioning trading
systems may result in settlement problems. In addition, corporate and
governmental data processing errors may result in production problems for
individual companies and create overall economic uncertainties. Earnings of
individual issuers will be affected by remediation costs which 

                                       34
<PAGE>
 
may be substantial. Individual firms may further experience disruptions to their
business due to the failure of their counterparts to address approaching year
2000 problems, or could experience further disruption to the economy at large,
which could adversely affect corporate earnings generally and the value of their
securities. Accordingly, a Fund's portfolio investments may be negatively
affected.

EUROPEAN ECONOMIC AND MONETARY UNION

Certain of the Funds will invest in European countries that have agreed to enter
into the European Monetary Union (EMU). EMU is an effort by certain European
countries to, among other things, reduce barriers between countries and
eliminate fluctuations in their currencies. Among other things, EMU establishes
a single European currency (the euro), which was introduced on January 1, 1999
and is expected to replace the existing national currencies of all initial EMU
participants by July 1, 2002. Upon introduction of the euro, certain securities
(beginning with government and corporate bonds) will be redonominated in the
euro and, thereafter will trade and make dividend and other payments only in
euros.

Like other investment companies and business organizations, including the
companies in which the Funds invest, the Funds could be adversely affected: (i)
if the euro, or EMU as a whole does not take effect as planned; (ii) if a
participating country withdraws from EMU; or (iii) if the computing, accounting
and trading systems used by the Funds' service providers, or by other business
entities with which the Funds or their service providers do business, are not
capable of recognizing the euro as a distinct currency at the time of, and
following euro conversion.

ADVISORY AGREEMENT      
- ------------------
    
The Company and the Adviser have entered into an Investment Advisory and
Management Agreement (the "Advisory Agreement"), under the terms of which the
Company has employed the Adviser to manage the investment of its assets, to
place orders for the purchase and sale of its portfolio securities, and to be
responsible for overall management of the Company's business affairs, subject to
control by the Board of Directors of the Company. The Adviser also pays certain
costs of marketing the Funds, including sales personnel compensation, from
legitimate profits from its investment advisory fees and other resources
available to it. In addition, the Adviser may reimburse third party
administrators for retirement plan shareholder servicing expenses.  Under the
Advisory Agreement, the Funds pay to the Adviser as compensation for the
services rendered, facilities furnished, and expenses paid by it the following
fees:      

                                          Annual Management Fee
                                         (As Percent of Average
FUND                                        Net Asset Value)

Total Return Mortgage-Backed Securities          .50%

High Yield Bond                                  .75%


The Advisory Agreement provides that the Adviser shall not be liable for any
error of judgment or mistake of law or for any loss suffered by a Fund in
connection with the matters to which the agreement relates, except a loss
resulting from willful misfeasance, bad faith, gross negligence on the part of
the Adviser in the performance of its duties or from reckless disregard by the
Adviser of its duties under the agreement.

MULTIPLE CLASS STRUCTURE
- ------------------------
    
Each Fund currently offers two classes of shares, Institutional Class shares and
Class N shares. Shares of each class of a Fund represents an equal pro rata
interest in that Fund and generally gives you the same voting, dividend,
liquidation, and other rights. The Institutional Class shares are offered at the
current net asset value. The Class N shares are also offered at the current net
asset value, but will be subject to fees imposed under a distribution plan
("Distribution Plan") adopted pursuant to Rule 12b-1 under the Investment
Company Act of 1940, as amended. Pursuant to the Distribution Plan, each Fund
compensates the Funds' distributor at a rate equal to 0.25% of the average daily
net assets of the Fund attributable to its Class N shares for distribution and
related services. Because these fees are paid out of the Fund's Class N assets 
on an on-going basis, over time, these fees will increase the cost of your 
investment and may cost you more than paying other types of sales charges.

                                YOUR INVESTMENT

ACCOUNT POLICIES AND SERVICES
- -----------------------------

BUYING SHARES
    
You pay no sales charges to invest in a Fund. Your price for Fund shares is the
Fund's net asset value per share (NAV) which is generally calculated as of the
close of trading on the New York Stock Exchange (usually 4:00 p.m. Eastern time)
every day the exchange is open. Your order will be priced at the next NAV
calculated after your order is accepted by the Fund. Orders received by a Fund's
Transfer Agent from dealers, brokers or other service providers after the NAV
for the day is determined will receive that same day's NAV if the orders were
received by the dealers, brokers or service providers from their customers prior
to 4:00 p.m. and were transmitted to and received by the Transfer Agent prior to
8:00 a.m. Eastern time on the next day. A Fund's investments are valued based on
market value, or where market quotations are not readily available, based on
fair value as determined in good faith by the Fund pursuant to procedures
established by the Fund's Board.      
 
          MINIMUMS

          TCW Galileo Funds, Inc. may waive the minimum and subsequent
          investments. All investments must be in U.S. dollars. Third-
          party checks, except those payable to an existing shareholder, 
          will normally not be accepted. If your check or wire does not 
          clear, you will be responsible for any loss a Fund incurs.

                                       40
<PAGE>
 
SELLING SHARES
- --------------

You may sell shares at any time. Your shares will be sold at the next NAV
calculated after your order is accepted by the Fund's transfer agent. Any
certificates representing Fund shares being sold must be returned with your
redemption request. Your order will be processed promptly and you will generally
receive the proceeds within a week.

Before selling recently purchased shares, please note that if the Fund has not
yet collected payment for the shares you are selling, it may delay sending the
proceeds for up to fifteen days.

WRITTEN SELL ORDER
- ------------------

Some circumstances require written sell orders, along with signature guarantees.
These include:

 .  amounts of $100,000 or more

 .  amounts of $1,000 or more on accounts whose address has been changed within
   the last 30 days

 .  requests to send the proceeds to a payee or address different than what is on
   our records

A SIGNATURE GUARANTEE helps protect against fraud. You can obtain one from most
- ---------------------
banks or securities dealers but not from a notary public. Please call us to
ensure that your signature guarantee will be processed correctly.

CHECK WRITING PRIVILEGE
    
You may request checks which may be drawn on your Money Market Fund account.
These checks may be drawn in amounts of $1,000 or more, may be made payable to
the order of any person and may be cashed or deposited. You can set up this
service with your New Account Form or by calling 800-386-3829.      

EXCHANGE PRIVILEGE
    
You can exchange from one Class I Galileo Fund into another. You can request
your exchange in writing or by phone. Be sure to read the current prospectus for
any Fund into which you are exchanging. Any new account established through an
exchange will have the same privileges as your original account (as long as they
are available).     

                                       41
<PAGE>
 
THIRD PARTY TRANSACTION

You may buy and redeem Fund shares through certain broker-dealers and financial
organizations and their authorized intermediaries. If purchases and redemptions
of Fund shares are arranged and settlement is made at an investor's election
through a registered broker-dealer, other than the Fund's distributor, that
broker-dealer may, at its discretion, charge a fee for that service.

ACCOUNT STATEMENTS

Every investor automatically receives regular account statements. You will also
be sent a yearly statement detailing the tax characteristics of any dividends
and distributions you have received.

LARGE REDEMPTION AMOUNTS
- ------------------------

Each Fund also reserves the right to make a "redemption in kind" - payment in 
portfolio securities rather than cash - if the amount you are redeeming in any 
90-day period is large enough to affect Fund operations (for example, if it 
equals more than $250,000 or represents more than 1% of the Fund's assets).

GENERAL POLICIES

For any Fund except the Money Market Fund, if your account falls below $25,000
as a result of redemptions and or exchanges for six months or more, the Fund may
close your account and send you the proceeds upon 60 days' written notice. If
your account with the Money Market Fund drops below $10,000 as a result of
redemptions and or exchanges, the Fund may close your account and send you the
proceeds upon 30 days' written notice.

Unless you decline telephone privileges on your New Account Form, you may be
responsible for any fraudulent telephone order as long as the Transfer Agent
takes reasonable measures to verify the order.

Each Fund restricts excessive trading (usually defined as more than four
exchanges out of the Fund within a calendar year). You are limited to one
exchange of shares in the same Fund during any 15-day period except the TCW
Galileo International Equities Fund, investors in 401(k) and other group

                                       42
<PAGE>
 
retirement accounts, investors who purchase shares through certain broker-
dealers and asset allocation accounts managed by the Adviser or an affiliate.
Each Fund reserves the right to:

 .  refuse any purchase or exchange request that could adversely affect a Fund or
   its operations, including those from any individual or group who, in the
   Fund's view, are likely to engage in excessive trading
    
 .  change or discontinue its exchange privilege, or temporarily suspend this
   privilege during unusual market conditions      
    
 .  delay sending out redemption proceeds for up to seven days (generally applies
   only in cases of very large redemptions, excessive trading or during unusual
   market conditions)

DISTRIBUTIONS AND TAXES
- -----------------------

The amount of dividends of net investment income and distributions of net
realized long and short-term capital gains payable to shareholders will be
determined separately for each Fund. Dividends from the net investment income of
each Fund except the Money Market Fund will be declared and paid monthly.
Dividends from net investment income for the Money Market Fund will be declared
and paid each weekday exclusive of days the New York Stock Exchange or the
Fund's custodian bank is closed. The Funds will distribute any net realized long
or short-term capital gains at least annually. Your distributions will be
reinvested in the fund unless you instruct the fund otherwise. There are no fees
or sales charges on reinvestments.

In any fiscal year in which the Funds qualify as regulated investment companies
and distribute to shareholders all of their net investment income and net
capital gains, the Funds are relieved of federal income tax.

Generally, all dividends and capital gains are taxable whether they are
reinvested or received in cash - unless you are exempt from taxation or entitled
to tax deferral. Capital gains distributions may be taxable at different rates
depending on the length of time a Fund has held the assets sold. Early each
year, you will be notified as to the amount and federal tax status of all
distributions paid during the prior year. Distributions may also be subject to
state or local taxes. The tax treatment of redemptions from a retirement plan
account may differ from redemptions from an ordinary shareholder account. If you
redeem shares of a Fund or exchange them for shares of another Fund, any gain on
the transaction may be subject to tax. You must provide the Funds with a correct
taxpayer identification number (generally your Social Security Number) and
certify that you are not subject to backup withholding. If you fail to do so,
the IRS can require the Funds to withhold 31% of your taxable distributions and
redemptions. Federal law also requires the Funds to withhold 30% or the
applicable tax treaty rate from dividends paid to nonresident alien, non-U.S.
partnership and non-U.S. corporation shareholder accounts.

This is a brief summary of some of the tax laws that affect your investment in
the Fund. Please see the Statement of Additional Information and your tax
adviser for further information.

FINANCIAL HIGHLIGHTS
- --------------------

The financial highlights table is intended to help you understand the Fund's
financial performance for the fiscal years indicated. Certain information
reflects financial results for a single Fund share. "Total return" shows how
much your investment in the Institutional Class shares of the Fund would have
increased (or decreased) during each period, assuming you had reinvested all
dividends and distributions. These figures have been audited by Deloitte &
Touche LLP, whose report, along with Company's financial statements, are
included in the annual report, which is available upon request.

The financial highlights table is intended to help you understand the Fund's
financial performance for the fiscal years indicated. Certain information
reflects financial results for a single Fund share. "Total return" shows how
much your investment in the Institutional Class shares of the Fund would have
increased (or decreased) during each period, assuming you had reinvested all
dividends and distributions. These figures have been audited by Deloitte &
Touche LLP, whose report, along with Company's financial statements, are
included in the annual report, which is available upon request.

INVESTMENT OBJECTIVES AND PRINCIPAL STRATEGIES
- --------------------------------------------------------------------------------
 
All of the Galileo Equity Funds are affected by changes in the economy, or in
securities and other markets. There is also the possibility that investment
decisions the Adviser makes will not accomplish what they were designed to
achieve or that companies in which the Funds invest will have disappointing
performance or not pay their debts.

</TABLE>

Under adverse market conditions, each Fund could invest some or all of its
assets in money market securities. Although the Funds would do this only in
seeking to avoid losses, it could have the effect of reducing the benefit from
any upswing in the market.

PRINCIPAL RISKS
- --------------------------------------------------------------------------------
 
Risk is the chance that you will lose money on your investment or that it will
not earn as much as you expect. In general, the greater the risk, the more money
your investment can earn for you and the more you can lose. Since shares of a
Fund represent an investment of securities with fluctuating market prices, the
value of Fund shares will vary as each Fund's portfolio securities increase or
decrease. Therefore, the value of an investment in a Fund could go down as well
as up. All investments are subject to:
     
 .  MARKET RISK     
 
   There is the possibility that the returns from the types of securities in
   which a Fund invests will underperform returns from the various general
   securities markets or different asset classes. Different types of securities
   tend to go through cycles of outperformance and underperformance in
   comparison to the general securities markets.
   
 .  SECURITIES SELECTION RISK
 
   There is the possibility that the specific securities held in a Fund's
   portfolio will underperform other funds in the same asset class or benchmarks
   that are representative of the general performance of the asset class because
   of the portfolio manager's choice of securities.
   
 .  PRICE VOLATILITY
 
   There is the possibility that the value of the Fund's portfolio will change
   as the prices of its investments go up or down. Although stocks offer the
   potential for greater long-term growth than most fixed income securities,
   stocks generally have higher short-term volatility.
   
   Each Fund may also be subject (in varying degrees) to the following risks:
 
 .  LIQUIDITY RISK
 
   There is the possibility that a Fund may lose money or be prevented from
   earning capital gains if it cannot sell a security at the time and price that
   is most beneficial to the Fund. The Earnings Momentum, Aggressive Growth
   Equities, Small Cap Growth, Small Cap Value, and Value Opportunities Funds
   are subject to liquidity risk because they invest primarily in securities of
   small or medium sized companies. The Convertible Securities Fund is subject
   to liquidity risk because it may invest in lower quality securities.
   
 .  FOREIGN INVESTING RISK
     
   There is the likelihood that foreign investments may be riskier than U.S.
   investments because of a lack of political stability, foreign controls on
   investment and currency exchange rates, fluctuations in currency exchange
   rates, withholding taxes, and lack of adequate company information. Each Fund
   is subject to foreign investing risk because it may invest in foreign company
   securities. In addition, because foreign securities generally are denominated
   and pay dividends or interest in foreign currencies, and each Fund may hold
   various foreign currencies, the value of the net assets of these Funds as
   measured in U.S. dollars can be affected favorably or unfavorably by changes
   in exchange rates.     

                                       5
<PAGE>
 
- --------------------------------------------------------------------------------
PRINCIPAL RISKS
- --------------------------------------------------------------------------------

 .  JUNK BONDS
 
These bonds are speculative in nature. They are usually issued by companies
without long track records of sales and earnings, or by those companies with
questionable credit strength. The Convertible Securities Fund's portfolio
consists, at times, primarily of below investment grade corporate securities.

Each Fund may be more susceptible to some of the risks discussed on the previous
page than others, as noted in the description of each Fund. A more detailed
explanation of these risks is presented under the "Risk Considerations" section
at page 34.

Because each Fund is non-diversified for 1940 Act purposes, it may invest more
than 5% of its total assets in the securities of any one issuer. Consequently,
its exposure to credit and market risks associated with that issuer is
increased.

Your investment is not a bank deposit, and it is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE SUMMARY
- --------------------------------------------------------------------------------
     
The two tables below show each Fund's annual returns and its long-term
performance with respect to its Institutional Class shares. The first table
shows you how the Fund's performance has varied from year to year. The second
compares the Fund's performance over time to that of a broad-based securities
market index. Both tables assume reinvestment of dividends and distributions.
The performance information includes the performance of predecessor limited
partnerships of each Fund, which were managed by an affiliate of TCW Funds
Management, INC., using the same investment strategy as the Funds. The
performance of the partnerships were calculated using performance standards
applicable to private investment partnerships, which take into account all
elements of total return and reflect the deduction of all fees and expenses of
operation, except for the Money Market and Total Return Mortgage-Backed
Securities Funds. The predecessor limited partnerships were not registered under
the Investment Company Act of 1940 ("1940 Act") and, therefore, were not subject
to certain investment restrictions imposed by the 1940 Act. If the limited
partnerships had been registered under the 1940 Act and Subchapter M of the
Internal Revenue Code of 1986 as amended, their performance might have been
adversely affected. As with all mutual funds, past performance is not a
prediction of future results.

Expense Example

This Example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other mutual funds.

This example shows what you could pay in expenses over time. It uses the same
hypothetical conditions other funds use in their prospectuses: $10,000 Initial
Investment, 5% total return each year and no changes in expenses. The figures
shown would be the same whether or not you sold your shares at the end of a
period. Because actual return and expenses will be higher or lower, the example
is for comparison purposes only.

Concepts to understand

Convertible securities are corporate securities that are exchangeable for a set
number of another form of security at a prestated price. They can be in the form
of equity or debt.

The Fund anticipates that it will primarily invest in convertible securities
that have a credit rating of at least B- or B3 by rating agencies such as
Moody's Investors Service, Inc. or Standard & Poor's Corporation or if unrated
are deemed of comparable quality by the Adviser. These securities are considered
to be mostly speculative in nature.
              
          The Fund seeks high total return from current income and capital
          appreciation. To pursue this goal, the Fund (except when maintaining a
          temporary defensive position) invests at least 65% of the value of its
          total assets in convertible securities.     

          In managing the Fund's investments, the Adviser considers the
          following factors when determining which securities to select:

          .  the Adviser's own evaluations of the creditworthiness of the
             issuers of the securities

          .  the interest or dividend income generated by the securities

          .  the potential for capital appreciation of the securities and the
             underlying common stocks

          .  the protection against price declines relative to the underlying
             common stocks

          .  the prices of the securities relative to other comparable 
             securities

          .  whether the securities have protective conditions

          .  the diversification of the Fund's investments

          .  the ratings assigned to the  securities

             Thomas D. Lyon and Kevin A. Hunter are the Fund's portfolio 
             managers.

          The Fund holds primarily convertible securities, which may go up or
          down in value, in accordance with moves in the convertible securities'
          underlying stock, sometimes rapidly and unpredictably.  Although
          stocks offer the potential for greater long-term growth than most
          fixed income securities, stocks generally have higher short-term
          volatility.

          The primary risks affecting this Fund are "credit risk," "interest
          rate risk," "liquidity risk" and, to a lesser extent, "foreign
          investing risk."

          Credit risk refers to the likelihood that the Fund could lose money if
          an issuer is unable to meet its financial obligations, such as the
          payment of principal and/or interest on an instrument, or goes
          bankrupt.  This Fund may be subject to greater credit risk, because it
          invests in convertible debt securities that are below investment
          grade.  Debt securities that are rated below investment grade are
          considered to be speculative.  These securities rated below investment
          grade are also commonly known as "junk" bonds.  This is especially
          true during periods of economic uncertainty or during economic
          downturns.  Below investment grade securities are often issued by
          companies without long track records of sales and earnings, or by
          those companies with questionable credit strength.  In the event of a
          prepayment problem by the issuer of these securities, they will only
          be paid if there is anything left after the payment of senior debt,
          such as bank loans and investment grade bonds.  Interest rate risk
          refers to the possibility that the value of the Fund's portfolio
          investments may fall since fixed income securities generally fall in
          value when interest rates rise.  The longer the term of a fixed income
          instrument, the more sensitive it will be to fluctuations in value
          from interest rate changes.  Liquidity risk refers to the possibility
          that the Fund may lose money or be prevented from earning capital
          gains if it cannot sell a security at the time and price that is most
          beneficial to the Fund.  Because lower quality securities may be less
          liquid than higher quality securities, the Fund may be more
          susceptible to liquidity risk than funds that invest in higher quality
          securities.  A security whose credit rating has been lowered may be
          particularly difficult to sell. Because the Fund may invest a portion
          of its assets in securities issued by foreign companies, it may be
          subject to foreign investing risks.  Foreign investing risk refers to
          the likelihood that foreign investments may be riskier than U.S.
          investments because of many factors, some of which include:

          .  a lack of political or economic stability

          .  foreign controls on investment and changes in currency exchange 
             rates

                                       14
<PAGE>
 
          .  withholding taxes

          .  a lack of adequate company information

          The risks of foreign investing are even more pronounced if the Fund
          invests in emerging markets.  In addition, securities traded only
          through foreign markets may be more volatile and are often harder to
          sell. Volatility is a way to measure the changes in the price of a
          single security or an entire portfolio.  Large and frequent price
          changes indicate higher volatility, which generally indicates that
          there is a greater chance you could lose money over the short term.
          The Fund is also subject to foreign currency risk.  Because foreign
          securities are generally denominated and pay dividends or interest in
          foreign currencies, the value of the net assets of the Fund as
          measured in United States dollars will be affected favorably or
          unfavorably by changes in exchange rates.

          The Fund seeks to earn additional income by making loans of its
          portfolio securities to brokers, dealers and other financial
          institutions.  The loans will be secured at all times by cash and
          liquid high grade debt obligations.  As with any extension of credit,
          there are risks of delay in recovery and in some cases even loss of
          rights in the collateral should the borrower fail financially.
              
          The Fund may engage in active portfolio management which may result in
          increased Fund transaction expenses and have tax consequences such as
          increased realized gains for investors.

Large capitalization companies are established companies that are considered 
known quantities. Large companies often have the resources to weather economic 
shifts, though they can be slower to innovate tank than small companies.

          The Fund seeks long-term capital appreciation.  Performance should be
          measured over a full market cycle.
    
          To pursue this goal, the Fund invests primarily in the common stocks
          of larger companies.  The investment philosophy underlying our
          strategy is a highly focused approach which seeks to achieve superior
          long-term returns by owning shares in companies that are believed to
          have strong and enduring business models and inherent advantages over
          their competitors.  Except when maintaining a temporary defensive
          position, the Fund anticipates that at least 65% of the value of its
          total assets will be invested in equity securities of these companies.
          In implementing its investment policy, the Fund may purchase and sell
          convertible securities and foreign securities.     

          Glen A. Bickerstaff is the Fund's portfolio manager.

          convertible debt securities are rated below investment grade and are

          and interest.

          The primary risks affecting this Fund are "price volatility" and
          "foreign investing risk."  Price volatility refers to the possibility
          that the value of the Fund's portfolio will change as the prices of
          its investments go up or down.  Although the Fund is subject to price
          volatility because of its stock investments, it is subject to less
          price volatility than funds that invest in the securities of smaller
          companies.  Because the Fund may invest a portion of its assets in
          securities issued by foreign companies, it may be subject to foreign
          investing risks.  Foreign investing risk refers to the likelihood that
          foreign investments may be riskier than U.S. investments because of
          many factors, some of which include:

          .  a lack of political or economic stability

          .  foreign controls on investment and currency exchange rates

          .  withholding taxes

          .  a lack of adequate company information

          In addition, securities traded only through foreign markets may be
          more volatile and are often harder to sell.  Volatility is a way to

          value of the net assets of the Fund as measured in United States
          dollars will be affected favorably or unfavorably by changes in
          exchange rates.

          The Fund may invest some assets in options, futures and foreign
          currency futures and forward contracts.  These practices are used
          primarily to hedge the Fund's portfolio but may be used to increase
          returns; however, such practices sometimes may reduce returns or
          increase volatility.

Earnings acceleration is the pattern of increasing rate of growth in a company 
or industry is typically triggered by a change that causes fundamentals to 
improve.

          The Fund seeks long-term capital appreciation. To pursue this goal,
          the Fund invests primarily in equity securities of companies
          experiencing or expected to experience accelerating earnings growth.
          The Fund will invest primarily in common stocks, but may also invest
          in convertible securities, warrants, options and foreign securities.

          The Adviser uses a "bottom-up" approach to identify industries or
          companies that are experiencing or expected to experience an
          acceleration in earnings growth.  It monitors the following changes in
          an attempt to identify these companies:

          .  changes in general economic, political or demographic trends

          .  development of new products or technology

          .  changes in consumer attitudes

          .  changes in a company's competitive advantage

          .  changes in the way a company is operated or valued

          refers to the possibility that the value of the Fund's portfolio will

          be subject to greater price volatility than funds that invest in the

          possibility that the Fund may lose money or be prevented from earning
          capital gains if it cannot sell securities at the time and price that
          is most beneficial to the Fund.  Because the securities of small-sized
          companies may be less liquid than the securities of large-sized
          companies, the Fund may be more susceptible to liquidity risk than
          funds that invest in the securities of large-sized companies.  Because
          the Fund may invest a portion of its assets in securities issued by
          foreign companies, it may be subject to foreign investing risks.
          Foreign investing risk refers to the likelihood that foreign

Large capitalization companies are established companies that are considered 
known quantities. Large capitalization companies often have the resources to 
weather economic shifts, although they can be slower to innovate than small 
companies.

Growth companies are companies exhibiting faster than average gains in earnings 
and which are expected to continue to show high levels of growth gain.
    
          The Fund seeks long-term capital appreciation. To pursue this goal,
          the Fund invests primarily in equity securities of large
          capitalization U.S. companies with above-average earnings prospects.
          It will invest (except when maintaining temporary defensive position)
          at least 65% of the value of its total assets in companies with a
          market capitalization of greater than $3 billion at the time of
          purchase.     

          In managing the Fund's investments, the Adviser seeks to invest in
          companies that will have reported earnings that exceed analysts'
          expectations (i.e., potential for earnings surprises).  The Adviser
                        ----                                                 
          utilizes "bottom-up" fundamental research to identify these companies.
          The Adviser performs fundamental research by using techniques such as:

          .  making company visits

          .  attending industry conferences

          .  maintaining communication with company management

          The Adviser then uses the information that it has obtained from its
          fundamental research to analyze the company's long-term growth
          potential, future earnings and cash flow.

          The Adviser uses quantitative and qualitative screening criteria to
          determine which companies to subject to its fundamental analysis.

          Wendy S. Barker and Douglas S. Foreman are the Fund's portfolio
          managers.

          volatility refers to the possibility that the value of the Fund's
          portfolio will change as the prices of its investments go up or down.
          This Fund may be less susceptible to price volatility risk because it

Large capitalization companies are established companies that are considered 
known quantities. Large capitalization companies often have the resources to 
weather economic shifts, though they can be slower to innovate than small 
companies.

Value companies are companies that appear underpriced according to certain 
financial measurements of their intrinsic worth or business prospects (such as 
price-to-earnings or price-to-book ratios). Because a stock can remain
undervalued for years, value investors often look for factors that could trigger
a rise in price.
    
          The Fund seeks long-term capital appreciation. To pursue this goal,
          the Fund invests primarily in equity securities of large
          capitalization companies. The securities include common and preferred
          stock and convertible securities. The Fund will invest (except when
          maintaining temporary defensive position) at least 65% of the value
          its total assets in publicly traded equity securities of companies
          with a market capitalization of greater than $3 billion at the time of
          purchase. The Fund will invest mostly in "value companies."    
    
          In managing the Fund's investments, the Adviser seeks to invest in
          attractively valued equity securities of companies where the return on
          invested capital is improving.  The Adviser utilizes bottom-up
          fundamental research to identify these companies.  The Adviser

             construction

          criteria to supplement the scope of fundamental research.

Emerging growth companies are companies that are likely to show rapid growth 
through reinventing an existing industry or pioneering a new industry.
    
          The Fund seeks long-term capital appreciation. To pursue this goal,
          the Fund anticipates that at least 65% of the value of its total
          assets will be invested (except when maintaining a temporary defensive
          position) in equity securities in issuers which are characterized as
          "growth" companies according to criteria established by the Adviser.
          These securities include common and preferred stock and convertible
          securities. In managing the Fund's investments, the Adviser will focus
          on emerging companies that exhibit this characteristic.     

          The Adviser utilizes a "bottom-up" approach to identify securities for
          investment.  First, the Adviser uses quantitative and qualitative
          criteria to screen companies.  The Adviser then subjects companies
          that make it through this screening process to fundamental analysis,
          which generally looks for at least some of the following factors:

          .  a demonstrated record of consistent earnings growth or the
             potential to grow earnings

          .  an ability to earn an attractive return on equity

          .  a price/earnings ratio which is less than the Adviser's internally
             estimated three-year earnings growth rate

          .  a large and growing market share

          .  a strong balance sheet

          .  significant ownership interest by management and a strong 
             management team.

          Christopher J. Ainley and Douglas S. Foreman are the Fund's portfolio

Small-Sized Companies seek long term capital appreciation by focusing on small, 
fast-growing companies that offer cutting-edge products, services or 
technologies. Because these companies are often in their early stages of 
development, their stocks tend to fluctuate more than most other securities.
              
          The Fund seeks long-term capital appreciation. To pursue this goal, it
          invests (except when maintaining a temporary defensive position) at
          least 65% of the value of its total assets in equity securities issued
          by companies with market capitalizations, at the time of acquisition,
          within the capitalization range of the companies comprising the
          Standard & Poor's Small Cap 600 Index.     

          In managing the Fund's investments, the Adviser pursues a small cap
          growth investment philosophy.  That philosophy consists of fundamental
          company-by-company analysis used in conjunction with technical and
          quantitative market analysis to screen potential investments and to
          continuously monitor securities in the Fund's portfolio.

          addition, the Fund may hold convertible debt securities.  Many
          convertible debt securities are rated below investment grade and are
          considered speculative by rating agencies as to repayment of principal
          and interest.

          The primary risks affecting this Fund are "price volatility" and
          "liquidity risk."  Price volatility refers to the possibility that the
          value of the Fund's portfolio will change as the prices of its
          investments go up or down.  This Fund may be subject to greater price
          volatility than funds that invest in the securities of large
          companies.  Liquidity risk refers to the possibility that the Fund may
          lose money or be prevented from earning capital gains if it cannot
          sell securities at the time and price that is most beneficial to the
          Fund.  Because the securities of small-size companies may be less
          liquid than the securities of large-size companies, the Fund may be
          susceptible to liquidity risk more than funds that invest in the
          securities of large-sized companies.

          The Fund may invest some assets in options.  This practice is used
          primarily to hedge the Fund's portfolio but may be used to increase
          returns; however, such practice sometimes may reduce returns or
          increase volatility.

          The Fund seeks to earn additional income by making loans of its
          portfolio securities to brokers, dealers and other financial
          institutions.  The loans will be secured at all times by cash and
          liquid high grade debt obligations.  As with any extension of credit,
          there are risks of delay in recovery and in some cases even loss of
          rights in the collateral should the borrower fail financially.
     
          The Fund may engage in active portfolio management which may result in
          increased Fund transaction expenses and have tax consequences, such as
          increased realized gains, for investors.

General Investment Risk
- -----------------------

Since shares of a Fund represent an investment in securities with fluctuating 
market prices, the value of Fund shares will vary as the value of each Fund's 
portfolio securities increases or decreases. Therefore, the value of an 
investment in a Fund could go down as well as up.

          Please consider the following risks before investing in a Fund.

          Various market risks can affect the price or liquidity of an issuer's
          securities.  Adverse events occurring with respect to an issuer's
          performance or financial position can depress the value of the
          issuer's securities.  The liquidity in a market for a particular
          security will affect its value and may be affected by factors relating
          to the issuer, as well as the depth of the market for that security.
          Other market risks that can affect value include a market's current
          attitudes about types of securities, market reactions to political or
          economic events, and tax and regulatory effects (including lack of
          adequate regulations for a market or particular type of instrument).
          Market restrictions on trading volume can also affect price and
          liquidity.

          Prices of many securities tend to be more volatile in the short-term.
          Therefore an investor who trades frequently or redeems in the short-
          term is more likely to incur loss than an investor who holds
          investments for the longer term.  The fewer the number of issuers in
          which a Fund invests, the greater the potential volatility of its
          portfolio.
     
          The Adviser may temporarily invest up to 100% of a Fund's assets in 
          high quality, short-term money market instruments if it believes
          adverse economic or market conditions, such as excessive volatility or
          sharp market declines, justify taking a defensive investment posture.
          If a Fund attempts to limit investment risk by temporarily taking a
          defensive investment position, it may be unable to pursue its
          investment objective during that time, and it may miss out on some or
          all of an upswing in the securities markets.

Foreign Investing
- --------------------


          Investment in foreign securities involves special risks in addition to
          the usual risks inherent in domestic investments.  These include:
          political or economic instability; the unpredictability of
          international trade patterns; the possibility of foreign governmental
          actions such as expropriation, nationalization or confiscatory
          taxation; the imposition or modification of foreign currency or
          foreign investment controls; the imposition of withholding taxes on
          dividends, interest and gains; price volatility; and fluctuations in
          currency exchange rates.

          As compared to United States companies, foreign issuers generally
          disclose less financial and other information publicly and are subject
          to less stringent and less uniform accounting, auditing and financial
          reporting standards.  Foreign countries typically impose less thorough
          regulations on brokers, dealers, stock exchanges, insiders and listed
          companies than does the United States, and foreign securities markets
          may be less liquid and more volatile than domestic markets.
          Investment in foreign securities involves higher costs than investment
          in U.S. securities, including higher transaction and custody costs as
          well as the imposition of additional taxes by foreign governments.  In
          addition, security trading practices abroad may offer less protection
          to investors such as the Funds.  Settlement of transactions in some
          foreign markets may be delayed or may be less frequent than in the
          U.S., which could affect the liquidity of each Fund's portfolio.
          Also, it may be more difficult to obtain and enforce legal judgments
          against foreign corporate issuers than against domestic

                                       35
<PAGE>
 
          issuers and it may be impossible to obtain and enforce judgments
          against foreign governmental issuers.

          Because foreign securities generally are denominated and pay dividends
          or interest in foreign currencies, and some of the Funds hold various
          foreign currencies from time to time, the value of the net assets of
          those Funds as measured in United States dollars will be affected
          favorably or unfavorably by changes in exchange rates.  Generally,
          currency exchange transactions will be conducted on a spot (i.e.,
          cash) basis at the spot rate prevailing in the currency exchange
          market.  The cost of currency exchange transactions will generally be
          the difference between the bid and offer spot rate of the currency
          being purchased or sold.  In order to protect against uncertainty in
          the level of future foreign currency exchange rates, each Fund is
          authorized to enter into certain foreign currency futures and forward
          contracts.  However, it is not obligated to do so and, depending on
          the availability and cost of these services, the Fund may be unable to
          use foreign currency futures and forward contracts to protect against
          currency uncertainty.  Please see the Statement of Additional
          Information for further information.

          The forward currency market for the purchase or sale of U.S. dollars
          in most countries is not highly developed, and in certain countries,
          there may be no such market.  If a devaluation of a currency is
          generally anticipated, a Fund may not be able to contract to sell the
          currency at an exchange rate more advantageous than that which would
          prevail after the anticipated amount of devaluation, particularly in
          regards to forward contracts for local Latin American currencies in
          view of the relatively small, inactive or even non-existent market for
          these contracts.  In the event the Funds hold securities denominated
          in a currency that suffers a devaluation, the Funds' net asset values
          will suffer corresponding reductions.  In this regard, in December
          1994, the Mexican government determined to allow the Mexican peso to
          trade freely against the U.S. dollar rather than within a controlled
          band, which action resulted in a significant devaluation of the
          Mexican peso against the dollar.  Further, in July 1997, the Thai and
          Philippine governments allowed the baht and peso, respectively, to
          trade freely against the U.S. dollar resulting in a sharp devaluation
          of both currencies, and in 1998 Russia did the same, causing a sharp
          devaluation of the ruble.

Fixed Income Securities
- -----------------------

          Fixed Income securities are subject to various risks.  The two primary
          (but not exclusive) risks affecting fixed income instruments are
          "credit risk" and "interest rate risk."  These risks can affect a
          security's price volatility to varying degrees, depending upon the
          nature of the instrument.  In addition, the depth and liquidity of the
          market for an individual or class of fixed income security can also
          affect its price and, hence, the market value of a Fund.

          "Credit risk" refers to the likelihood that an issuer will default in
          the payment of principal and/or interest on an instrument.  Financial
          strength and solvency of an issuer are the primary factors influencing
          credit risk.  In addition, lack of or inadequacy of collateral or
          credit enhancements for a fixed income security may affect its credit
          risk.  Credit risk of a security may change over its life, and
          securities which are rated by rating agencies are often reviewed and
          may be subject to downgrade.

          Each Galileo Equity Fund may invest in convertible securities rated
          below investment grade.  Debt securities that are rated below
          investment grade are considered to be speculative.  Those securities
          rated below investment grade are also commonly known as "junk" bonds.
          Generally, lower-rated debt securities provide a higher yield than
          higher rated debt securities of similar maturity but are subject to
          greater credit risk than higher rated securities of similar maturity.
          Such securities are regarded as predominantly speculative with respect
          to the issuer's continuing ability to meet principal and interest
          payments.  Because investment in lower 

                                       37
<PAGE>
 
          quality securities involves greater investment risk, achievement of a
          Fund's investment objective will be more dependent on the Adviser's
          analysis than would be the case if the Fund were investing in higher
          quality bonds. In addition, lower quality securities may be more
          susceptible to real or perceived adverse economic and individual
          corporate developments than would investment grade bonds. Moreover,
          the secondary trading market for lower quality securities may be less
          liquid than the market for investment grade bonds. This potential lack
          of liquidity may make it more difficult for the Adviser to value
          accurately certain portfolio securities.

          "Interest rate risk" refers to the risks associated with market
          changes in interest rates.  Interest rate changes may affect the value
          of a fixed income security directly (especially in the case of fixed
          rate securities) and indirectly (especially in the case of adjustable
          rate securities).  In general, rises in interest rates will negatively
          impact the price of fixed rate securities and falling interest rates
          will have a positive effect on price.  The degree to which a
          security's price will change as a result of changes in interest rates
          is measured by its "duration."  For example, the price of a bond with
          a 5 year duration would be expected under normal market conditions to
          decrease 5% for every 1% increase in interest rates.  Generally,
          securities with longer maturities have a greater duration and thus are
          subject to greater price volatility from changes in interest rates.
          Adjustable rate instruments also react to interest rate changes in a
          similar manner although generally to a lesser degree (depending,
          however, on the characteristics of the reset terms, including the
          index chosen, frequency of reset and reset caps or floors, among other
          things).

Non-Diversified Status
- ----------------------

          Each of the Galileo Equity Funds is non-diversified for 1940 Act
          purposes and as such may invest a larger percentage of its assets in
          individual issuers than a diversified investment company. In this
          regard, the Fund is not subject to the general limitation that it not
          invest more than 5% of its total assets in the securities of any one
          issuer. To the extent the Fund makes investments in excess of 5% of
          its assets in a particular issuer, its exposure to credit and market
          risks associated with that issuer is increased. However, each Fund's
          investments will be limited so as to qualify for the special tax
          treatment afforded "regulated investment companies" under the Internal
          Revenue Code of 1986, as amended.

Year 2000
- ------------------
    
          The investment advisory and management services provided by the
          Adviser and the services provided to shareholders by the Transfer
          Agent depend on the smooth functioning of their computer systems.
          Many computer software systems in use today cannot recognize the year
          2000, but revert to 1900 or some other date, due to the manner in
          which dates were encoded and calculated.  That failure could have a
          negative impact on the handling of securities trades, pricing and
          account services.  The Adviser and the Transfer Agent have been
          actively working on necessary changes to their own computer systems to
          prepare for the year 2000 and expect that their systems will be
          adapted for year 2000 compliance before that date, but there can be no
          assurance that they will be successful, or that interaction with other
          non-complying computer systems will not impair their services at that
          time.  The Adviser has been, and is currently in contact with, each of
          its External Service Providers to evaluate their readiness for the
          year 2000.  The Adviser has requested each of its External Service
          Providers to either (i) prepare a description of its process for
          identifying date sensitive areas, its approach for implementing
          changes, its testing methodology, along with its timetable for
          completion, or (ii) certify as to its year 2000 compliance.     

          In addition, it is possible that the markets for securities in which
          the Funds invest may be negatively affected by computer failures
          throughout the financial services industry commencing January 1, 2000.
          Improperly functioning trading systems may result in settlement
          problems.  In addition, corporate and governmental data processing
          errors may result in production problems for individual companies and
          create overall economic uncertainties.  Earnings of individual issuers
          will be affected by remediation costs which may be substantial.
          Individual firms may further experience disruptions to their

          problems, or could experience further disruption to the economy at
          large, which could adversely affect corporate earnings generally and
          the value of their securities. Accordingly, a Fund's portfolio
          investments may be negatively affected.

European Economic and Monetary Union
- --------------------------------------
    
          Certain of the Funds will invest in European countries that have
          agreed to enter into the European Monetary Union (EMU).  EMU is an
          effort by certain European countries to, among other things, reduce
          barriers between countries and eliminate fluctuations in their
          currencies.  Among other things, EMU establishes a single European
          currency (the euro), which was introduced on January 1, 1999 and is
          expected to replace the existing national currencies of all initial
          EMU participants by July 1, 2002.  Upon introduction of the euro,
          certain securities (beginning with government and corporate bonds)
          have been redonominated in the euro and, thereafter trade and make
          dividend and other payments only in euros.       
    
          Like other investment companies and business organizations, including
          the companies in which the Funds invest, the Funds could be adversely
          affected: (i) if the euro, or EMU as a whole does not take affect;
          (ii) if a participating country withdraws from EMU; or (iii) if the
          computing, accounting and trading systems used by the Funds' service
          providers, or by other business entities with which the Funds or their
          service providers do business, are not capable of recognizing the euro
          as a distinct currency at the time of, and following euro
          conversion.

          Advisory Agreements

          The Company and the Adviser have entered into an Investment Advisory
          and Management Agreement (the "Advisory Agreement"), under the terms
          of which the Company has employed the Adviser to manage the investment
          of its assets, to place orders for the purchase and sale of its
          portfolio securities, and to be responsible for overall management of
          the Company's business affairs, subject to control by the Board of
          Directors of the Company.  The Adviser also pays certain costs of
          marketing the Funds, including sales personnel compensation, from
          legitimate profits from its investment advisory fees and other
          resources available to it.  In addition, the Adviser may reimburse
          third party administrators for retirement plan shareholder servicing
          expenses.  Under the Advisory Agreement, the Funds pay to the Adviser
          as compensation for the services rendered, facilities furnished, and
          expenses paid by it the following fees:

          The Advisory Agreement provides that the Adviser shall not be liable
          for any error of judgment or mistake of law or for any loss suffered
          by a Fund in connection with the matters to which the agreement
          relates, except a loss resulting from willful misfeasance, bad faith
          or gross negligence on the part of the Adviser in the performance of
          its duties or from reckless disregard by the Adviser of its duties
          under the agreement.

LOGO      MULTIPLE CLASS STRUCTURE
- ----------------------------------
    
          Each Fund currently offers two classes of shares, Institutional Class
          shares and Class N shares.  Shares of each class of a Fund represents
          an equal pro rata interest in that Fund and generally give you the
          same voting, dividend, liquidation, and other rights.  The
          Institutional Class shares are offered at the current net asset value.
          The Class N shares are also offered at the current net asset value,
          but will be subject to fees imposed under a distribution plan
          ("Distribution Plan") adopted pursuant to Rule 12b-1 under the
          Investment Company Act of 1940, as amended. Pursuant to the
          Distribution Plan, each Fund compensates the Funds' distributor at a
          rate equal to 0.25% of the average daily net assets of the Fund
          attributable to its Class N shares for distribution and related
          services. Because these fees are paid out of the Fund's Class N assets
          on an on-going basis, over time, these fees will increase the cost of
          your investment and may cost you more than paying other types of sales
          charges.

LOGO      ACCOUNT POLICIES AND SERVICES
- ---------------------------------------

          Buying shares
    
          You pay no sales charges to invest in a Fund. Your price for Fund
          shares is the Fund's net asset value per share (NAV) which is
          calculated as of the close of trading on the New York Stock Exchange
          (usually 4:00 p.m. Eastern time) every day the exchange is open. Your
          order will be priced at the next NAV calculated after your order is
          accepted by the Fund. Orders received by a Fund's transfer agent from
          dealers, brokers or other service providers after NAV for the day is
          determined will receive that same day's NAV if the orders were
          received by the dealers, brokers or service providers from their
          customers prior to 4:00 P.M. and were transmitted to and received by
          the transfer agent prior to 8:00 a.m. Eastern time on the next day. A
          Fund's investments are valued based on market value, or where market
          quotations are not readily available, based on fair value as
          determined in good faith by the Fund pursuant to procedures
          established by the Fund's board.

          Selling shares

          You may sell shares at any time.  Your shares will be sold at the next
          NAV calculated after your order is accepted by the Fund's Transfer
          Agent.  Any certificates representing Fund shares being sold must be
          returned with your redemption request.  Your order will be processed
          promptly, and you will generally receive the proceeds within a week.

          Before selling recently purchased shares, please note that if the Fund
          has not yet collected payment for the shares you are selling, it may
          delay sending the proceeds for up to fifteen days.

          Written sell order

          Some circumstances require written sell orders, along with signature
          guarantees.  These include:

          .  amounts of $100,00 or more

          .  amounts of $1,000 or more on accounts whose address has been
             changed within the last 30 days

          .  requests to send the proceeds to a payee or address different than
             what is on our records

          A signature guarantee helps protect against fraud.  You can obtain one
          from most banks or securities dealers but not from a notary public.
          Please call us to ensure that your signature guarantee will be
          processed correctly.

          Exchange privilege
    
          You can exchange from one Class I Galileo Fund into another.  You can
          request your exchange in writing or by phone. Be sure to read the
          current prospectus for any Fund into which you are exchanging. Any new
          account established through an exchange will have the same privileges
          as your original account (as long as they are available).      

          Third Party Transaction

          You may buy and redeem Fund shares through certain broker-dealers and
          financial organizations and their authorized intermediaries.  If
          purchases and redemptions of Fund shares are arranged and settlement
          is made at an investor's election through a registered broker-dealer,
          other than the Fund's distributor, that broker-dealer may, at its
          discretion, charge a fee for that service.

          Account statements

          Every Fund investor automatically receives regular account statements.
          You will also be sent a yearly statement detailing the tax
          characteristics of any dividends and distributions you have received.

    General policies

    For any Fund, if your account falls below $25,000 as a result of redemptions
    and or exchanges for six months or more, the Fund may close your account and
    send you the proceeds upon 60 days' written notice.

LARGE REDEMPTION AMOUNTS
- ------------------------

Each Fund also reserves the right to make a "redemption in kind" -- payment in
portfolio securities rather than cash -- if the amount you are redeeming in any
90-day period is large enough to affect Fund operations (for example, if it
equals more than $250,000 or represents more than 1% of the Fund's assets).
    
    Unless you decline telephone privileges on your New Account Form, you may
    be responsible for any fraudulent telephone order as long as the Transfer
    Agent takes reasonable measures to verify the order.
    
    Each Fund restricts excessive trading (usually defined as more than four
    exchanges out of the Fund within a calendar year).  You are limited to one
    exchange of shares in the same Fund during any 15-day period except
    investors in 401(k) and other group retirement accounts, investors who
    purchase shares through certain broker-dealers and asset allocation
    accounts managed by the Adviser or an affiliate.  Each Fund reserves the
    right to:

    .  refuse any purchase or exchange request that could adversely affect a
       Fund or its operations, including those from any individual or group who,
       in the Fund's view, are likely to engage in excessive trading

    .  change or discontinue its exchange privilege, or temporarily suspend this
       privilege during unusual market conditions

    .  delay sending out redemption proceeds for up to seven days (generally
       applies only in cases of very large redemptions, excessive trading or
       during unusual market conditions)

LOGO      DISTRIBUTIONS AND TAXES
- ---------------------------------

          The amount of dividends of net investment income and distributions of
          net realized long and short-term capital gains payable to shareholders
          will be determined separately for each Fund. Dividends from the net
          investment income of each Fund will be declared and paid annually
          except for the Convertible Securities Fund, which will declare and pay
          dividends quarterly.  The Funds will distribute any net realized long
          or short-term capital gains at least annually.  Your distributions
          will be reinvested in the fund unless you instruct the fund otherwise.
          There are no fees or sales charges on reinvestments.

          In any fiscal year in which the Funds qualify as regulated investment
          companies and distribute to shareholders all of their net investment
          income and net capital gains, the Funds are relieved of Federal income
          tax.

          Generally, all dividends and capital gains are taxable whether they
          are reinvested or received in cash - unless you are exempt from
          taxation or entitled to tax deferral.  Capital gains distributions may
          be taxable at different rates depending on the length of time a Fund
          has held the assets sold.  Early each year, you will be notified as to
          the amount and Federal tax status of all distributions paid during the
          prior year.  Distributions may also be subject to state or local
          taxes.  The tax treatment of redemptions from a retirement plan
          account may differ from redemptions from an ordinary shareholder
          account.  If you redeem shares of a Fund or exchange them for shares
          of another Fund, any gain on the transaction may be subject to tax.
          You must provide the Funds with a correct taxpayer identification
          number (generally your Social Security Number) and certify that you
          are not subject to backup withholding.  If you fail to do so, the IRS
          can require the Funds to withhold 31% of your taxable distributions
          and redemptions.  Federal law also requires the Funds to withhold 30%
          or the applicable tax treaty rate from dividends paid to nonresident
          alien, non-U.S. partnership and non-U.S. corporation shareholder
          accounts.

          This is a brief summary of some of the tax laws that affect your
          investment in the Fund.  Please see the Statement of Additional
          Information and your tax adviser for further information.

          Fund's financial performance for the fiscal years indicated.  Certain
          information reflects financial results for a single Fund share.
          "Total return" shows how much your investment in the Institutional

          each period, assuming you had reinvested all dividends and
          distributions.  These figures have been audited by Deloitte & Touche

          The financial highlights table is intended to help you understand the
          Fund's financial performance for the fiscal years indicated.  Certain
          information reflects financial results for a single Fund share.
          "Total return" shows how much your investment in the Institutional
          Class shares of the Fund would have increased (or decreased) during
          each period, assuming you had reinvested all dividends and
          distributions.  These figures have been audited by Deloitte & Touche
          LLP, whose report, along with Company's financial statements, are
          included in the annual report, which is available upon request.

INVESTMENT OBJECTIVES AND PRINCIPAL STRATEGIES

All of the Galileo Institutional Funds are affected by changes in the economy,
or in securities and other markets. There is also the possibility that
investment decisions the Adviser makes will not accomplish what they were
designed to achieve or that companies in which the Funds invest will have
disappointing performance or not pay their debts.

</TABLE>      

Under adverse market conditions, each Fund could invest some or all of its
assets in money market securities. Although the Fund will do this only in
seeking to avoid losses, it could have the effect of reducing the benefit from
any upswing in the market.

PRINCIPAL RISKS
 
Risk is the chance that you will lose money on your investment or that it will
not earn as much as you expect. In general, the greater the risk, the more money
your investment can earn for you and the more you can lose. Since shares of a
Fund represent an investment in securities with fluctuating market prices, the
value of Fund shares will vary as the value of each Fund's portfolio securities
increases or decreases. Therefore, the value of an investment in a Fund could go
down as well as up. All investments are subject to:
    
 .    MARKET RISK     
 
     There is the possibility that the returns from the types of securities in
     which a Fund invests will underperform returns from the various general
     securities markets. Different types of securities tend to go through cycles
     of outperformance and underperformance in comparison to the general
     securities markets.
     
 .    SECURITIES SELECTION RISK
 
     There is the possibility that the specific securities held in the Funds'
     portfolio will underperform the other funds in the same asset class or
     benchmarks that are representative of the general performance of the asset
     class because of the portfolio manager's choice of securities.
 
 .    FOREIGN INVESTING RISK
 
     There is the likelihood that foreign investments may be riskier than U.S.
     investments because of a lack of political stability, foreign controls on
     investment and currency exchange rates, fluctuations in currency exchange
     rates, withholding taxes, and lack of adequate company information. Each
     Fund is subject to foreign investing risk because it invests primarily in
     the assets of foreign governments or companies. Because each Fund (except
     the Japanese Equities Fund) invests in securities of emerging market
     countries, the risk factors listed above are more likely to occur. In
     addition, because foreign securities generally are denominated and pay
     dividends or interest in foreign currencies, and the Galileo International
     Funds hold various foreign currencies, the value of the net assets of these
     Funds as measured in United States dollars will be affected favorably or
     unfavorably by changes in exchange rates.

Each Fund may also be subject (in varying degrees) to the following risks:
 
 .    LIQUIDITY RISK
 
     There is the possibility that a Fund may lose money or be prevented from
     earning capital gains if it cannot sell a security at the time and price
     that is most beneficial to the Fund. Each Fund is subject to liquidity risk
     because foreign securities may be less liquid than U.S. securities.
     
 .    PRICE VOLATILITY
 
     There is the possibility that the value of the Fund's portfolio will change
     as the prices of its investments go up or down. Although stocks offer the
     potential for greater long-term growth than most fixed income securities,
     stocks generally have higher short-term volatility. Each Fund (except the
     Emerging Markets Income Fund) is subject to this risk. In addition, the
     Emerging Markets Income Fund is subject to price volatility because it
     invests in low rated emerging market debt.
     
Because the Galileo International Funds are non-diversified for 1940 Act
purposes, they may invest more than 5% of its total assets in the securities of
any one issuer. Consequently, their exposure to credit and market risks
associated with that issuer is increased.

Your investment is not a bank deposit, and it is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency.

The two tables below show each Fund's annual returns and its long-term
performance with respect to its Institutional Class shares. The first table
shows you how the Fund's performance has varied from year to year. The second
compares the Fund's performance over time to that of a broad-based securities
index. Both tables assume reinvestment of dividends and distributions. The
performance information includes the performance of each Fund's predecessor
limited partnerships, which were managed by an affiliate of TCW Funds
Management, INC., using the same investment strategy as the Funds. The
performance of the partnerships were calculated using performance standards
applicable to private investment partnerships, which take into account all
elements of total return and reflect the deduction of all fees and expenses of
operation, except for the European Equities Fund. The predecessor limited
partnerships were not registered under the Investment Company Act of 1940 ("1940
Act") and, therefore, were not subject to certain investment restrictions
imposed by the 1940 Act. If the limited partnerships had been registered under
the 1940 Act and Subchapter M of the Internal Revenue Code of 1986 as amended,
their performance might have been adversely affected. As with all mutual funds,
past performance is not a prediction of the future.

EXPENSE EXAMPLE

This Example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other mutual funds. 

This example shows what you could pay in expenses over time. It uses the same
hypothetical conditions other funds use in their prospectuses: $10,000 Initial
Investment, 5% total return each year and no changes in expenses. The figures
shown would be the same whether or not you sold your shares at the end of a
period. Because actual return and expenses will be higher or lower, the example
is for comparison purposes only.

INVESTMENT OBJECTIVES/APPROACH                                        
    
          The Fund seeks long-term capital appreciation.  To pursue this goal,
          it invests in equity securities of companies in the Asia Pacific
          Region ("Asia-Pacific Countries"), except Australia, Japan and New
          Zealand. At least 65% of the value of the Fund's total assets will be
          invested (except when maintaining a temporary defensive position) in
          equity securities of Asia Pacific Companies, or securities convertible
          into such equity securities.     

          The Fund will generally invest its portfolio securities among at least
          three Asia Pacific Countries.

          In managing the Fund's investments, the Adviser utilizes an investment
          process that incorporates both a "top-down" and "bottom-up" analysis
          of the Asia-Pacific Countries.  The "top-down" analysis focuses on an
          evaluation of the global environment. The Adviser then complements its
          "top-down" analysis with a "bottom-up" analysis.  The Adviser uses
          "bottom-up" analysis to determine country allocation based on
          estimated earnings.  The key factors used by the Adviser in assessing
          the potential for an expansion (rerating) or contraction (derating) of
          a stock market's earnings multiple are:

          .  liquidity

          .  historical valuations

          .  the sustainability of economic growth and political environment

          The Adviser then performs an industry analysis and screens companies
          based on certain quantitative analyses.

Concepts to understand

Asian Pacific Company (i) is organized under the laws of an Asia-Pacific Country
and has a principal office in Asia; or (ii)derives 50% or more of its gross
revenues or profits from goods produced or sold, investments made, or services
performed in Asia-Pacific Countries or has at least 50% of its assets situated
in Asia-Pacific Countries; or (iii) its equity securities are traded principally
on a stock exchange or over-the-counter in an Asia-Pacific country.

MAIN RISKS

          The Fund holds primarily stocks, which may go up or down in value,
          sometimes rapidly and unpredictably. Although stocks offer the
          potential for greater long-term growth than most fixed income
          securities, stocks generally have higher short-term volatility. In
          addition, the Fund may hold convertible debt securities. Many
          convertible debt securities are rated below investment grade and are
          considered speculative by rating agencies as to repayment of principal
          and interest.

          The primary risks affecting this Fund are "foreign investing risk,"
          "liquidity risk" and "price volatility." Because the Fund invests
          almost all of its assets in securities issued by foreign companies, it
          is subject to foreign investing risks. Foreign investing risk refers
          to the likelihood that foreign investments may be riskier than U.S.
          investments because of many factors, some of which include:

          . a lack of political or economic stability

          . foreign controls on investment and currency exchange rates

          . withholding taxes

          . a lack of adequate company information

          Because the Fund invests in the securities of emerging market
          countries, these risks are more pronounced. In addition, securities
          traded only through foreign markets may be more volatile and are often
          harder to sell. The Fund also is subject to foreign currency risk.
          Because foreign securities generally are denominated and pay dividends
          or interest in foreign currencies, the value of the net assets of the
          Fund as measured in United States dollars will be affected favorably
          or unfavorably by changes in exchange rates. LIQUIDITY RISK refers to
          the possibility that the Fund may lose money or be prevented from
          earning capital gains if it cannot sell a security at the time and
          price that is most beneficial to the Fund. Because foreign securities
          may be less liquid than U.S. securities, the Fund may be more
          susceptible to liquidity risk than funds that invest in U.S.
          securities. PRICE VOLATILITY refers to the possibility that the value
          of the Fund's portfolio will change as the prices of its investments
          go up or down. This Fund may be subject to greater price volatility
          than funds that invest in the securities of U.S. companies.

          The Fund may invest some assets in foreign currency futures, forward
          contracts, options and futures. These practices are used primarily to
          hedge

                                       12
<PAGE>
 

          the Fund's portfolio but may be used to increase returns; however,
          such practices sometimes may reduce returns or increase volatility.

          The Fund seeks to earn additional income by making loans of its
          portfolio securities to brokers, dealers and other financial
          institutions. The loans will be secured at all times by cash and
          liquid high grade debt obligations. As with any extension of credit,
          there are risks of delay in recovery and in some cases even loss of
          rights in the collateral should the borrower fail financially.
    
          The Fund may engage in active portfolio management which may result in
          increased Fund transaction expenses and have tax consequences, such as
          increased realized gains, for investors.

INVESTMENT OBJECTIVES/APPROACH

          The Fund seeks long-term capital appreciation. To pursue this goal, it
          invests primarily in equity securities of companies in Emerging Market
          Countries.
    
          The Fund will generally invest its assets among at least five Emerging
          Market Countries. At least 65% of the value of its total assets will
          be invested (except when maintaining a temporary defensive position)
          in Emerging Market Company equity-related securities.     

          In managing the Fund's investments, the Adviser utilizes both a "top-
          down view" and a "bottom-up analysis". In allocating investments among
          Emerging Market Counties, the Adviser attempts to integrate an
          assessment of how the global environment affects a particular country,
          with an analysis of internal political, market and economic factors.
          Among the country economic variables examined are:

          .  level of economic activity or GDP growth
          
          .  level and direction of local inflation

          .  level and direction of interest rates

          .  monetary policy and money supply growth

          .  current account balances and financing requirements

          .  the pace and degree of privatization

          Based on these analyses, the Adviser estimates the overall earnings
          growth rate (in local currency and in U.S. dollars) of the corporate
          sector within each country. Market valuation levels are examined and
          compared with historical levels and the levels of other Emerging
          Market Countries that have gone through similar stages of economic

Concepts to Understand

Emerging Market Country is a country that has a developing economy or market and
is considered an emerging or developing country by the International Bank of 
Reconstruction and Development or any affiliate thereof (the "World Bank"), as 
well as Hong Kong, Israel and Singapore.

Emerging Market Company: (i) is organized under the laws of an Emerging Market 
Country and has a principal office in an Emerging Market Country; or (ii) 
derives 50% or more of its gross revenues or profits from goods produced or 
sold, investments made, or services performed in Emerging Market Countries or 
has at least 50% of its assets situated in Emerging Market Countries; or (iii) 
its equity securities are traded principally on a stock exchange or

          development. These analyses and estimates form the basis for a
          calculation of the expected return for each market, which is a key
          element of country allocation. The next step in the investment
          decision process is industry analysis within sectors, which includes
          assessing the effects of such developments as privatization programs,
          infrastructure investments, consumer trends and government regulation
          on particular industry sectors. The Adviser attempts to identify the
          sectors that would benefit from structural changes. The Adviser also
          considers the possible impact of short-term cyclical factors, such as
          business and political cycles, on particular industries. These
          analyses produce industry weightings for each market.

          In selecting Emerging Market Companies for investment, the Adviser
          takes into account a variety of factors, including price/earnings
          ratio, earnings growth, quality of management, availability of new
          products and markets, current and historical stock prices, sales
          growth and country factors affecting particular companies.

          The Fund seeks high total return from current income and capital
          appreciation. To pursue this goal, it invests (except when maintaining
          a temporary defensive position) at least 65% of the value of its total
          assets in debt securities issued or guaranteed by companies, financial
          institutions and government entities in Emerging Market Countries. The
          debt securities in which the Fund may invest may consist of securities
          that are unrated or rated BB or lower by S&P or Ba or lower by
          Moody's. Debt securities rated below investment grade are the
          equivalent of high yield, high risk bonds, commonly known as "junk
          bonds." The Fund will invest in at least four Emerging Market
          Countries.     

          In allocating investments among the various Emerging Market Countries,
          the Adviser attempts to analyze internal political, market and

          .  withholding taxes

          .  a lack of adequate company information

          Because the Fund invests in the securities of emerging market
          countries, these risk factors are more pronounced. In addition,
          securities traded only through foreign markets may be more volatile
          and are often harder to sell. The Fund also is subject to foreign
          currency risk. Because foreign securities generally are denominated
          and pay dividends or interest in foreign currencies, the value of the
          net assets of the Fund as measured in United States dollars will be
          affected favorably or unfavorably by changes in exchange rates.
          LIQUIDITY RISK refers to the possibility that the Fund may lose money
          or be prevented from earning capital gains if it cannot sell a
          security at the time and price that is most beneficial to the Fund.
          Because lower quality securities and foreign securities may be less
          liquid than higher quality securities, the Fund may be more
          susceptible to liquidity risk than funds that invest in higher quality
          or U.S. securities. CREDIT RISK refers to the likelihood that the Fund
          could lose money if an issuer is unable to meet its financial
          obligations, such as the payment of principal and/or interest on an
          instrument, or goes bankrupt. This Fund may be subject to greater
          credit risk, because it invests in securities that are below
          investment grade and have no minimum credit rating. Debt securities
          that are rated below investment grade are considered to be
          speculative. Those securities rated below investment grade are also
          commonly known as "junk" bonds. This is especially true during periods
          of economic uncertainty or during economic downturns. INTEREST RATE
          RISK refers to the possibility that the value of the Fund's portfolio
          investments may fall when interest rates rise. Changes in interest
          rates may have a significant effect on the Fund, because it may hold
          securities with long terms to maturity and may use hedging techniques.
          PRICE VOLATILITY refers to the possibility that the value of the
          Fund's portfolio
                          
                                      19

          will change as the value of its investments go up or down. The Fund
          may be subject to greater price volatility than funds that invest in
          the securities of U.S. issuers.      

          The Fund may invest some assets in options, futures, foreign currency
          futures and forward contracts. These practices are used primarily to
          hedge the Fund's portfolio but may be used to increase returns;
          however, such practices sometimes may reduce returns or increase
          volatility.

          The Fund seeks to earn additional income by making loans of its
          portfolio securities to brokers, dealers and other financial
          institutions. The loans will be secured at all times by cash and
          liquid high grade debt obligations. As with any extension of credit,
          there are risks of delay in recovery and in some cases even loss of
          rights in the collateral should the borrower fail financially.
     
          The Fund may engage in active portfolio management which may result in
          increased Fund transaction expenses and have tax consequences, such as
          increased realized gains, for investors.

                      TCW GALILEO EUROPEAN EQUITIES FUND

INVESTMENT OBJECTIVES/APPROACH
                                            
          The Fund seeks long-term capital appreciation. To pursue this goal, it
          invests primarily in the securities of issuers located in Europe. The
          Fund invests (except when maintaining a temporary defensive position)
          at least 65% of the value of its total assets in equity securities
          issued by European companies. These securities include common and
          preferred stocks, rights or warrants to purchase common stock and
          convertible debt or equity securities. The Fund invests in companies
          based in at least three European Countries.     

          In managing the Fund's investments, the Adviser seeks to emphasize
          companies which are moving towards the North American concept of
          shareholder value.

          The Adviser also seeks investment opportunities resulting from the
          fact that economic ties between the former "Eastern bloc" countries of
          Europe and other European countries have been strengthened. The Fund
          will not invest more than 30% of its total assets in issuers based in
          former "Eastern bloc" countries, or more than 10% of its total assets
          in issuers based in any one former "Eastern bloc" country.

          JAMES M. BURNS AND SAKER A. NUSSEIBEH ARE THE FUND'S PORTFOLIO
          MANAGERS.

Concepts to understand

European Company (i) is organized under the laws of a European country and has 
a principal office in Europe; or (ii) derives 50% or more of its gross revenues 
or profits from goods produced or sold, investments made, or services performed 
in European countries or has at least 50% of its assets situated in Europe; or 
(iii) its equity securities are traded principally on a stock exchange or 
over-the-counter in a European country.

MAIN RISKS

          The Fund holds primarily stocks, which may go up or down in value,
          sometimes rapidly and unpredictably. Although stocks offer the
          potential for greater long-term growth than most fixed income
          securities, stocks generally have higher short-term volatility. In
          addition, the Fund may hold convertible debt securities. Many
          convertible debt securities are rated below investment grade and are
          considered speculative by rating agencies as to repayment of principal
          and interest.

          The primary risks affecting this Fund are "foreign investing risk,"
          "liquidity risk," and "price volatility." The Fund is subject to
          foreign investing risk because it invests in securities issued by
          foreign governments or companies. FOREIGN INVESTING RISK refers to the
          likelihood that foreign investments may be riskier than U.S.
          investments because of many factors, some of which include:

          . a lack of political or economic stability

          . foreign controls on investment and currency exchange rates

          . withholding taxes

          . a lack of adequate company information

          Because the Fund invests in the securities of emerging market
          countries, these risk factors are more pronounced. In addition,
          securities traded only through foreign markets may be more volatile
          and are often harder to sell. The Fund is also subject to foreign
          currency risk. Because foreign securities generally are denominated
          and pay dividends or interest in foreign currencies, the value of the
          net assets of the Fund as measured in United States dollars will be
          affected favorably or unfavorably by changes in exchange rates.
          LIQUIDITY RISK refers to the possibility that the Fund may lose money
          or be prevented from earning capital gains if it cannot sell a
          security at the time and price that is most beneficial to the Fund.
          Because foreign securities may be less liquid than U.S. securities,
          the Fund may be more susceptible to liquidity risk than funds that
          invest in U.S. securities. PRICE VOLATILITY refers to the possibility
          that the value of the Fund's portfolio will change as the prices of
          its investments go up or down. This Fund may be subject to greater
          price volatility than funds that invest in the securities of U.S.
          companies.

          The Fund may invest some assets in options, futures, foreign currency
          futures and forward contracts. These practices are used primarily to

                    TCW GALILEO INTERNATIONAL EQUITIES FUND

INVESTMENT OBJECTIVES/APPROACH

          This Fund seeks long-term capital appreciation. To pursue its goal, it
          invests primarily in equity markets outside the U.S. both in developed
          and emerging countries through investment in shares of the Galileo
          Funds.

          In managing the Fund's assets, the Fund allocates its assets, within
          predetermined percentage ranges, among certain of the underlying
          Galileo Funds which, except for the TCW Galileo Money Market Fund,
          invest predominantly in foreign securities. The Fund will invest
          (except when maintaining a temporary defensive position) in the
          following underlying Galileo Funds up to the percentage limits set
          forth below:

          The Fund may invest directly in Australian and New Zealand securities.
          The Board may alter these percentage limits when it deems appropriate.

          Each underlying Galileo Fund has a specific investment objective,
          investment policies and risks. Investors should read the disclosure
          contained in this Prospectus regarding each underlying Galileo Fund's
          investment objective, policies, permissible investments and risks. The
          TCW Galileo Money Market Fund invests in high credit quality, short-
          term money market securities.

MAIN RISKS

          The Fund holds primarily shares of other funds.

          The primary risks affecting the Fund are "foreign investing risk,"
          "liquidity risk" "price volatility," and to a lesser extent, "credit
          risk." Because the Fund will invest most of its assets in underlying
          Galileo Funds, which invest in securities issued by foreign
          governments or companies, it is subject to FOREIGN INVESTING RISKS.
          Foreign investing risk refers to the likelihood that foreign
          investments may be riskier than U.S. investments because of many
          factors, some of which include:

          .  a lack of political or economic stability

          .  foreign controls on investment and currency exchange rates

          .  withholding taxes

          .  a lack of adequate company information

          Because the Fund invests in underlying Galileo Funds, which invest in
          the securities of emerging market countries, these risks are more
          pronounced. In addition, securities traded only through foreign
          markets may be more volatile and are often harder to sell. The Fund
          also is subject to foreign currency risk. Because foreign securities
          generally are denominated and pay dividends or interest in foreign
          currencies, the value of the net assets of those Funds as measured in
          United States dollars will be affected favorably or unfavorably by
          changes in exchange rates. LIQUIDITY RISK refers to the possibility
          that the Fund may lose money or be prevented from earning capital
          gains if it cannot sell a security at the time and price that is most
          beneficial to the Fund. Because foreign securities may be less liquid
          than U.S. securities, the Fund may be more susceptible to liquidity
          risk than funds that invest in U.S. securities. PRICE VOLATILITY
          refers to the possibility that the value of the Fund's portfolio will
          change as the value of its investments go up or down. The Fund may be
          subject to greater price volatility than funds that invest in the
          securities of U.S. companies.

          Investing in the underlying Galileo Funds through the Fund involves
          certain additional expenses and taxes that would not be present in
          direct investments in the underlying Galileo Funds.

          The Fund invests in underlying Galileo Funds, which seek to earn
          additional income by making loans of their portfolio securities to
          brokers, dealers and other financial institutions. The loans will be
          secured at all times by cash and liquid high grade debt obligations.
          As with any extension of credit,

          there are risks of delay in recovery and in some cases even loss of
          rights in the collateral should the borrower fail financially.
    
          The Fund may engage in active portfolio management which may result in
          increased Fund transaction expenses and have tax consequences, such as
          increased realized gains, for investors.

                      TCW GALILEO JAPANESE EQUITIES FUND

INVESTMENT OBJECTIVES/APPROACH
    
          The Fund seeks long-term capital appreciation. To pursue this goal, it
          invests (except when maintaining a temporary defensive position) at
          least 65% of the value of its total assets in equity securities issued
          by Japanese Companies. These securities include common and preferred
          stocks, rights or warrants to purchase common stock and convertible
          debt or equity securities.     
    
          The Fund may invest up to 25% of the value of its total assets in
          equity securities of Japanese Companies traded on the second sections
          of the main Japanese exchanges and in the over-the-counter market
          which generally are smaller companies. The Fund will invest in
          companies that the Adviser believes:     

          .  have potential for good medium term earnings growth

          .  are undervalued within the Japanese equities market

          The Adviser will seek companies that have at least some of the
          following characteristics:

          .  strong balance sheets

          .  strong management team

          .  high quality assets

          .  large market share

          The Fund also may invest up to 35% of its total assets in debt
          securities of issuers located in Japan or issued or guaranteed by the
          Japanese government.
    
   Stephen J. Harker and PeTER A. Kirkman are the Fund's portfolio managers.

          The primary risks affecting this Fund are "foreign investing risk,"
          "single country risk," "liquidity risk," "price volatility" and
          "credit risk." Because the Fund invests in securities issued by
          foreign governments or companies, it is subject to FOREIGN INVESTING
          RISKS. Foreign investing risk refers to the likelihood that foreign
          investments may be riskier than U.S. investments because of many

          value of the net assets of those Funds as measured in United States
          dollars will be affected favorably or unfavorably by changes in

          may lose money or be prevented from earning capital gains if it cannot
          sell a security at the time and price that is most beneficial to the
          Fund. Because foreign securities may be less liquid than U.S.
          securities, the Fund may be more susceptible to liquidity risk than
          funds that invest in U.S. securities. In addition, because the Fund
          may invest in the securities of small-sized companies, these
          securities may be less liquid than the securities of large-sized
          companies. PRICE VOLATILITY refers to the possibility that the value
          of the Fund's portfolio will change as the prices of its investments
          go up or down. The Fund may be subject to greater price volatility
          than funds that invest in the securities of large U.S. companies. The
          Fund is subject to "SINGLE COUNTRY" RISK. As a "single country" mutual
          fund, the Fund may exhibit certain speculative

                                       28
<PAGE>


          characteristics and thus should not constitute a complete investment
          program. The concentration of the Fund's assets in Japanese issuers
          will subject the Fund to the risks of adverse social, political or
          economic events which occur in Japan. CREDIT RISK refers to the
          likelihood that the Fund could lose money if an issuer is unable to
          meet its financial obligations, such as the payment of principal
          and/or interest on an instrument, or goes bankrupt. The Fund may be
          subject to substantial credit risk because it may invest in securities
          that are below investment grade. Debt securities that are rated below
          investment grade are considered to be speculative. Those securities
          rated below investment grade are also commonly known as "junk" bonds.

          The Fund may invest some assets in options, futures, foreign currency
          futures and forward contracts. It may also sell short securities These
          practices are used primarily to hedge the Fund's portfolio but may be
          used to increase returns; however, such practices sometimes may reduce
          returns or increase volatility.

          The Fund seeks to earn additional income by making loans of its
          portfolio securities to brokers, dealers and other financial
          institutions. The loans will be secured at all times by cash and
          liquid high grade debt obligations. As with any extension of credit,
          there are risks of delay in recovery and in some cases even loss of
          rights in the collateral should the borrower fail financially.
    
          The Fund may engage in active portfolio management which may result in
          increased Fund transaction expenses and have tax consequences, such as
          increased realized gains, for investors.

                    TCW GALILEO LATIN AMERICA EQUITIES FUND

INVESTMENT OBJECTIVES/APPROACH
    
          The Fund seeks long-term capital appreciation. To pursue this goal, it
          invests (except when maintaining a temporary defensive position) at
          least 65% of the value of its total assets in Latin American equity
          securities. The Fund invests its assets among at least three Latin
          American countries at all times. Typically, 95% of the Fund's
          investments will consist of equity securities of issuers in Brazil,
          Mexico, Argentina, Chile, Columbia, Peru and Venezuela.     

          Other Latin American countries in which the Fund may invest are: the
          Bahamas, Barbados, Belize, Bolivia, Costa Rica, Dominican Republic,
          Ecuador, El Salvador, French Guinea, Guatemala, Guyana, Haiti,
          Honduras, Jamaica, the Netherlands, Antilles, Nicaragua, Panama,
          Paraguay, Suriname, Trinidad, Tobago, and Uruguay.

          The Fund seeks superior returns by investing in countries, or sectors
          within countries, exhibiting strong earnings growth potential in U.S.
          dollar terms as well as reasonable value. Allocation of assets among
          Latin American countries is based on the risk adjusted attractiveness
          of each market.

          The Adviser carries out both country political and economic analysis
          in order to identify attractive investment opportunities. This
          analysis involves:

          .  internal research

          .  in-country visits with government officials, business leaders, and
             private sector consultants

          .  communicating with multilateral agencies such as the World Bank, 
             IMF, and IADB

Concepts to understand

Latin American securities include (i) debt or equity securities of companies 
organized in a country in Latin America or for which the principal trading 
market (the exchange or over-the-counter market in which the largest portion of 
the shares of the company's securities are traded) is located in Latin America, 
(ii) equity securities of companies that derive at least 50% of their gross 
revenues or profits from either goods produced or services performed in Latin 
America or sales made in Latin America, (iii) equity securities in the form of 
Depositary instruments listed on securities exchanges or traded in other 
regulated markets in the United States issued by companies which meet the 
requirements set forth in clauses (i) and (ii), (iv) debt securities issued or 
guaranteed by the government of a country in Latin America, its agencies or 
instrumentalities, or the central bank of such country, and (v) debt securities 
denominated in a Latin American currency issued by companies to finance 
operations in Latin America.

MAIN RISKS

          The Fund holds primarily stocks, which may go up or down in value,
          sometimes rapidly and unpredictably. Although stocks offer the
          potential for greater long-term growth than most fixed income
          securities, stocks generally have higher short-term volatility. In
          addition, the Fund may hold convertible debt securities. Many
          convertible debt securities are rated below investment grade and are
          considered speculative by rating agencies as to repayment of principal
          and interest.

          The primary risks affecting this Fund are "foreign investing risk,"
          "liquidity risk," and "price volatility." Because the Fund invests a
          portion of its assets in securities issued by foreign governments or
          companies, it may be subject to FOREIGN INVESTING RISKS. Foreign
          investing risk refers to the likelihood that foreign investments may
          be riskier than U.S. investments because of many factors, some of
          which include :

          .  a lack of political or economic stability                  

          .  foreign controls on investment and currency exchange rates 

          .  withholding taxes                                          

          .  a lack of adequate company information                      

          Because the Fund invests in the securities of emerging market
          countries, these risks are more pronounced. In addition, securities
          traded only through foreign markets may be more volatile and are often
          harder to sell. The Fund also is subject to foreign currency risk.
          Because foreign securities generally are denominated and pay dividends
          or interest in foreign currencies, and some of the Funds hold various
          foreign currencies from time to time, the value of the net assets of
          those Funds as measured in United States dollars will be affected
          favorably or unfavorably by changes in exchange rates. LIQUIDITY RISK
          refers to the possibility that the Fund may lose money or be prevented
          from earning capital gains if it cannot sell a security at the time
          and price that is most beneficial to the Fund. Because lower quality
          securities and foreign securities may be less liquid than higher
          quality or U.S. securities, the Fund may be more susceptible to
          liquidity risk than funds that invest in higher quality or U.S.
          investments. PRICE VOLATILITY refers to the possibility that the value
          of the Fund's portfolio will change as the prices of its investments
          go up or down. This Fund may be subject to greater price volatility
          than funds that invest in the securities of large U.S. companies.

                                       32
<PAGE>
 
          The Fund may invest some assets in options, futures, foreign currency
          futures and forward contracts. These practices are used primarily to
          hedge the Fund's portfolio but may be used to increase returns;
          however, such practices sometimes may reduce returns or increase
          volatility.

          The Fund seeks to earn additional income by making loans of its
          portfolio securities to brokers, dealers and other financial
          institutions. The loans will be secured at all times by cash and
          liquid high grade debt obligations. As with any extension of credit,
          there are risks of delay in recovery and in some cases even loss of
          rights in the collateral should the borrower fail financially.
    
          The Fund may engage in active portfolio management which may result in
          increased Fund transaction expenses and have tax consequences, such as
          increased realized gains, for investors.

RISK CONSIDERATIONS

          Please consider the following risks before investing in a Fund.

          Various market risks can affect the price or liquidity of an issuer's
          securities. Adverse events occurring with respect to an issuer's
          performance or financial position can depress the value of the
          issuer's securities. The liquidity in a market for a particular
          security will affect its value and may be affected by factors relating
          to the issuer, as well as the depth of the market for that security.
          Other market risks that can affect value include a market's current
          attitudes about type of security, market reactions to political or
          economic events, and tax and regulatory effects (including the lack of
          adequate regulations for a market or particular type of instrument).
          Market restrictions on trading volume can also affect price and
          liquidity.

          Prices of most securities tend to be more volatile in the short-term.
          Therefore, an investor who trades frequently or redeems in the short-
          term is more likely to incur loss than an investor who holds
          investments for the long term. The fewer the number of issuers in
          which a Fund invests, the greater the potential volatility of its
          portfolio.
     
          The Adviser may temporarily invest up to 100% of the Fund's assets in
          high quality, short-term money market instruments if it believes
          adverse economic or market conditions, such as excessive volatility or
          sharp market declines, justify taking a defensive investment posture.
          If the Fund attempts to limit investment risk by temporarily taking a
          defensive investment position, it may be unable to pursue its
          investment objective during that time, and it may miss out on some or
          all of an upswing in the securities markets.     

General Investment Risk

Since shares of a Fund represent an investment in securities with fluctuating 
market prices, the value of Fund shares will vary as the value of each Fund's 
portfolio securities increases or decreases. Therefore, the value of an 
investment in a Fund could go down as well as up.

RISK CONSIDERATIONS

          Investment in foreign securities involves special risks in addition to
          the usual risks inherent in domestic investments. These include:
          political or economic instability; the unpredictability of
          international trade patterns; the possibility of foreign governmental
          actions such as expropriation, nationalization or confiscatory
          taxation; the imposition or modification of foreign currency or
          foreign investment controls; the imposition of withholding taxes on
          dividends, interest and gains; price volatility; and fluctuations in
          currency exchange rates.

          As compared to United States companies, foreign issuers generally
          disclose less financial and other information publicly and are subject
          to less stringent and less uniform accounting, auditing and financial
          reporting standards. Foreign countries typically impose less thorough
          regulations on brokers, dealers, stock exchanges, insiders and listed
          companies than does the United States. Foreign securities markets may
          be less liquid and more volatile than domestic markets. Investment in
          foreign securities involves higher costs than investment in U.S.
          securities, including higher transaction and custody costs as well as
          the imposition of additional taxes by foreign governments. In
          addition, security trading practices abroad may offer less protection
          to investors such as the Funds. Settlement of transactions in some
          foreign markets may be delayed or may be less frequent than in the
          U.S., which could affect the liquidity of each Fund's portfolio. Also,
          it may be more difficult to obtain and enforce legal judgments against
          foreign corporate issuers than against

          domestic issuers and it may be impossible to obtain and enforce
          judgments against foreign governmental issuers.
    
          Because foreign securities generally are denominated and pay dividends
          or interest in foreign currencies, and some of the Funds hold various
          foreign currencies from time to time, the value of the net assets of
          those Funds as measured in United States dollars will be affected
          favorably or unfavorably by changes in exchange rates. Generally,
          currency exchange transactions will be conducted on a spot (i.e.,
          cash) basis at the spot rate prevailing in the currency exchange
          market. The cost of currency exchange transactions will generally be
          the difference between the bid and offer spot rate of the currency
          being purchased or sold. In order to protect against uncertainty in
          the level of future foreign currency exchange rates, the Galileo
          International Funds are authorized to enter into certain foreign
          currency futures and forward contracts. However, they are not
          obligated to do so and, depending on the availability and cost of
          these devices, the Funds may be unable to use foreign currency futures
          and forward contracts to protect against currency uncertainty. Please
          see the Statement of Additional Information for further information.
     
          With respect to the Emerging Markets Equities, Emerging Markets
          Income, and Latin America Equities Funds, the forward currency market
          for the purchase or sale of U.S. dollars in most Latin American
          countries is not highly developed, and, in certain countries, there
          may be no such market. If a devaluation of a currency is generally
          anticipated, the Funds may not be able to contract to sell the
          currency at an exchange rate more advantageous than that which would
          prevail after the anticipated amount of devaluation, particularly in
          regard to forward contracts for local currencies in view of the
          relatively small, inactive or even non-existent market for these
          contracts. In the event the Funds hold securities denominated in a
          currency that suffers a devaluation, the Funds' net asset values will
          suffer corresponding reductions. In this regard, in December 1994, the
          Mexican government determined to allow the Mexican peso to trade
          freely against the U.S. dollar rather than within a controlled band,
          which action resulted in a significant devaluation of the Mexican peso
          against the dollar. Further, in July 1997, the Thai and Philippine
          governments allowed the baht and peso, respectively, to trade freely
          against the U.S. dollar resulting in a sharp devaluation of both
          currencies, and in 1998 Russia did the same, causing a sharp
          devaluation of the ruble.

RISK CONSIDERATIONS

          Investors should recognize that investing in securities of emerging
          market countries through investment in the Asia Pacific Equities,
          Emerging Markets Equities, Emerging Markets Income, European Equities,
          International Equities and Latin America Equities Funds involves
          certain risks, and considerations, including those set forth below,
          which are not typically associated with investing in the United States
          or other developed countries.

          Political and economic structures in many emerging markets countries
          may be undergoing significant evolution and rapid development, and
          such countries may lack the social, political and economic stability
          characteristics of more developed countries. Some of these countries
          may have in the past failed to recognize private property rights and
          have at times nationalized or expropriated the assets of private
          companies.

          The securities markets of emerging market countries are substantially
          smaller, less developed, less liquid and more volatile than the major
          securities markets in the United States and other developed nations.
          The limited size of many emerging securities markets and limited
          trading volume in issuers compared to the volume of trading in U.S.
          securities or securities of issuers in other developed countries could
          cause prices to be erratic for reasons apart from factors that affect
          the quality of the securities. For example, limited market size may
          cause prices to be unduly influenced by traders who control large
          positions. Adverse publicity and investors' perceptions, whether or
          not based on

Risks Associated With Emerging Market Countries

                                       37
<PAGE>
 
          fundamental analysis, may decrease the value and liquidity of
          portfolio securities, especially in these markets.

          In addition, emerging market countries' exchanges and broker-dealers
          are generally subject to less government and exchange regulation than
          their counterparts in developed countries. Brokerage commissions,
          dealer concessions, custodial expenses and other transaction costs may
          be higher in emerging markets than in developed countries. As a
          result, Funds investing in emerging market countries have operating
          expenses that are expected to be higher than other Funds investing in
          more established market regions.

          Many of the emerging market countries may be subject to a greater
          degree of economic, political and social instability than is the case
          in the United States, Canada, Australia, New Zealand, Japan and
          Western European and certain Asian countries. Such instability may
          result from, among other things, (i) popular unrest associated with
          demands for improved political, economic and social conditions, and
          (ii) internal insurgencies. Such social, political and economic
          instability could disrupt the financial markets in which the Asia
          Pacific Equities, Emerging Markets Equities, Emerging Markets Income,
          International Equities and Latin America Equities Funds invest and
          adversely affect the value of a Fund's assets.

          In certain emerging market countries governments participate to a
          significant degree, through ownership or regulation, in their
          respective economies. Action by these governments could have a
          significant adverse effect on market prices of securities and payment
          of dividends. In addition, most emerging market countries have
          experienced substantial, and in some periods extremely high, rates of
          inflation. Inflation and rapid fluctuation in inflation rates have had
          and may continue to have very negative effects on the economies and
          securities markets of certain emerging market countries. In addition,
          many emerging market countries are grappling with severe recession and
          government instability.

          Many of the currencies of emerging market countries have experienced
          devaluations relative to the U.S. dollar, and major devaluations have
          historically occurred in certain countries. Any devaluations in the
          currencies in which portfolio securities are denominated will have a
          detrimental impact on Funds investing in emerging market countries.
          Many emerging market countries are experiencing currency exchange
          problems.

          Countries have and may in the future impose foreign currency controls
          and repatriation control.

RISK CONSIDERATIONS

          Fixed income securities are subject to various risks. The two primary
          (but not exclusive) risks affecting fixed income instruments are
          "credit risk" and "interest rate risk." These risks can affect a
          security's price volatility to varying degrees, depending upon the
          nature of the instrument. In addition, the depth and liquidity of the
          market for an individual or class of fixed income security can also
          affect its price and, hence, the market value of a Fund.

          "CREDIT RISK" refers to the likelihood that an issuer will default in
          the payment of principal and/or interest on an instrument. Financial
          strength and solvency of an issuer are the primary factors influencing
          credit risk. In addition, lack of or inadequacy of collateral or
          credit enhancements for a fixed income security may affect credit
          risk. Credit risk of a security may change over its life and
          securities which are rated by rating agencies are often reviewed and
          may be subject to downgrades.

          The Emerging Markets Income Fund may invest in debt instruments rated
          below investment grade. Debt securities that are rated below
          investment grade are considered to be speculative. Those securities
          rated below investment grade are also commonly known as "junk" bonds.
          Generally, lower-rated debt securities provide a higher yield than
          higher rated debt securities of similar maturity but are subject to
          greater credit risk than higher rated securities of similar maturity.
          Such securities are regarded as predominantly speculative with respect
          to the issuer's continuing ability to meet principal and interest
          payments. Because investment in lower quality securities involves
          greater investment risk, achievement of a Fund's investment objective
          will be more dependent on the Adviser's analysis than

Fixed Income Securities

                                      40
<PAGE>
 
          would be the case if the Fund were investing in higher quality bonds.
          In addition, lower quality securities may be more susceptible to real
          or perceived adverse economic and individual corporate developments
          than would investment grade bonds. Moreover, the secondary trading
          market for lower quality securities may be less liquid than the market
          for investment grade bonds. This potential lack of liquidity may make
          it more difficult for the Adviser to value accurately certain
          portfolio securities.

          "INTEREST RATE RISK" refers to the change in value of debt instruments
          associated with changes in interest rates. Interest rate changes may
          affect the value of a fixed income security directly (especially in
          the case of fixed rate securities) and indirectly (especially in the
          case of adjustable rate securities). In general, rises in interest
          rates will negatively impact the value of fixed rate securities and
          falling interest rates will have a positive effect on value. The
          degree to which a security's price will change as a result of changes
          in interest rates is measured by its "duration." For example, the
          price of a bond with a 5 year duration would be expected under normal
          market conditions to decrease 5% for every 1% increase in interest
          rates. Generally, securities with longer maturities have a greater
          duration and thus are subject to greater price volatility from changes
          in interest rates. Adjustable rate instruments also react to interest
          rate changes in a similar manner although generally to a lesser degree
          (depending, however, on the characteristics of the reset terms,
          including the index chosen, frequency of reset and reset caps or
          floors, among other things).

RISK CONSIDERATIONS

          Each of the Galileo International Funds are non-diversified for 1940
          Act purposes and as such may invest a larger percentage of its assets
          in individual issuers than a diversified investment company. In this
          regard, the Fund is not subject to the general limitation that it not
          invest more than 5% of its total assets in the securities of any one
          issuer. To the extent the Fund makes investments in excess of 5% of
          its assets in a particular issuer, its exposure to credit and market
          risks associated with that issuer is increased. However, the Fund's
          investments will be limited so as to qualify for the special tax
          treatment afforded "regulated investment companies" under the Internal
          Revenue Code of 1986, as amended.

RISK CONSIDERATIONS
    
          The investment advisory and management services provided by the
          Adviser and the services provided to shareholders by the Transfer
          Agent depend on the smooth functioning of their computer systems. Many
          computer software systems in use today cannot recognize the year 2000,
          but revert to 1900 or some other date, due to the manner in which
          dates were encoded and calculated. That failure could have a negative
          impact on the handling of securities trades, pricing and account
          services. The Adviser and the Transfer Agent have been actively
          working on necessary changes to their own computer systems to prepare
          for the year 2000 and expect that their systems will be adapted for
          year 2000 compliance before that date, but there can be no assurance
          that they will be successful, or that interaction with other non-
          complying computer systems will not impair their services at that
          time. The Adviser has been, and is currently in contact with, each of
          its External Service Providers to evaluate their readiness for the
          year 2000. The Adviser has requested each of its External Service
          Providers to either; (i) prepare a description of its process for
          identifying date sensitive areas, its approach for implementing
          changes, its testing methodology, along with its timetable for
          completion, or (ii) certify as to its year 2000 compliance.     

          In addition, it is possible that the markets for securities in which
          the Funds invest may be negatively affected by computer failures
          throughout the financial services industry commencing January 1, 2000.

          addition, corporate and governmental data processing errors may result
          in production problems for individual companies and create overall
          economic uncertainties. Earnings of individual issuers will be
          affected by remediation costs which may be substantial. Individual
          firms may further experience disruptions to their business due to the
          failure of their counterparts to address year 2000 problems, or could
          experience further disruption to the economy at large, which could
          adversely affect corporate earnings generally and the value of their
          securities. Accordingly, a Fund's portfolio investments may be
          negatively affected.

RISK CONSIDERATIONS
    
          Certain of the Funds will invest in European countries that have
          agreed to enter into the European Monetary Union (EMU). EMU is an
          effort by certain European countries to, among other things, reduce
          barriers between countries and eliminate fluctuations in their
          currencies. Among other things, EMU establishes a single European
          currency (the euro), which was introduced on January 1, 1999 and is
          expected to replace the existing national currencies of all initial
          EMU participants by July 1, 2002. Upon introduction of the euro,
          certain securities (beginning with government and corporate bonds)
          have been redonominated in the euro and, thereafter trade and make
          dividend and other payments only in euros.     
    
          Like other investment companies and business organizations, including
          the companies in which the Funds invest, the Funds could be adversely
          affected: (i) if the euro, or EMU as a whole does not take effect (ii)
          if a participating country withdraws from EMU; or (iii) if the
          computing, accounting and trading systems used by the Funds' service
          providers, or by other business entities with which the Funds or their
          service providers do business, are not capable of recognizing the euro
          as a distinct currency at the time of, and following euro
          conversion.

ADVISORY AGREEMENT      

          The Company and the Adviser have entered into an Investment Advisory
          and Management Agreement (the "Advisory Agreement"), under the terms
          of 

                                       47
<PAGE>
 
    
          which the Company has employed the Adviser to manage the investment
          of its assets, to place orders for the purchase and sale of its
          portfolio securities, and to be responsible for overall management of
          the Company's business affairs, subject to control by the Board of
          Directors of the Company.  The Adviser also pays certain costs of
          marketing the Funds, including sales personnel compensation, from
          legitimate profits from its investment advisory fees and other
          resources available to it.  In addition, the Adviser may reimburse
          third party administrators for retirement plan shareholder servicing
          expenses. Under the Advisory Agreement, the Funds pay to the Adviser
          as compensation for the services rendered, facilities furnished, and
          expenses paid by it the following fees:     

                                                                        
                                     Annual Management Fee
Fund                                (As Percent of Average Net Asset Value)
- ----                                ---------------------------------------
Asia Pacific Equities               1.00%
Emerging Markets Equities           1.00%
Emerging Markets Income              .75%
European Equities                    .75%
Latin America Equities              1.00%
International Equities              -----
Japanese Equities                    .75%

          The Advisory Agreement for International Equities provides that the
          Fund does not pay a direct management fee.  However, as a "Fund of
          Funds" investing its assets in a mix of other Galileo Funds,
          International Equities will bear its proportionate share of the
          management fee of any other Fund in which it invests.

          The Adviser has retained, at its sole expense, TCW Asia to provide
          investment advisory services for the Asia Pacific Equities and
          Emerging Markets Equities Funds, and TCW London to provide such
          services with respect to the Emerging Markets Equities, European
          Equities, International Equities and Japanese Equities Funds.  Under
          the Sub-Advisory Agreements the Sub-Advisers assist the Adviser in
          performing its advisory functions in respect of the Funds.

                                      48
<PAGE>
     
          The Advisory and Sub-Advisory Agreements provide that the Adviser and
          Sub-Advisers, respectively, shall not be liable for any error of
          judgment or mistake of law or for any loss suffered by a Fund in
          connection with the matters to which the agreements relate, except a
          loss resulting from willful misfeasance, bad faith or gross negligence
          on the part of the Adviser or Sub-Advisers in the performance of their
          duties or from reckless disregard by them of their duties under each
          respective agreement.      

MULTIPLE CLASS STRUCTURE
    
          Each Fund currently offers two classes of shares, Institutional Class
          shares and Class N shares.  Shares of each class of a Fund represents
          an equal pro rata interest in that Fund and generally gives you the
          same voting, dividend, liquidation, and other rights.  The
          Institutional Class shares are offered at the current net asset value.
          The Class N shares are also offered at the current net asset value,
          but will be subject to fees imposed under a distribution plan
          ("Distribution Plan") adopted pursuant to Rule 12b-1 under the
          Investment Company Act of 1940, as amended.  Pursuant to the
          Distribution Plan, each Fund compensates the Funds' distributor at a
          rate equal to 0.25% of the average daily net assets of that Fund
          attributable to its Class N shares for distribution and related
          services. Because these fees are paid out of the Fund's Class N assets
          on an on-going basis, over time, these fees will increase the cost of
          your investment and may cost you more than paying other types of
          sales charges.

                                YOUR INVESTMENT
ACCOUNT POLICIES AND SERVICES

Buying shares
    
     You pay no sales charges to invest in a Fund.  Your price for Fund shares
     is the Fund's net asset value per share (NAV) which is calculated as of the
     close of trading on the New York Stock Exchange (usually 4:00 p.m. Eastern
     time) every day the exchange is open. Your order will be priced at the next
     NAV calculated after your order is accepted by the Fund. Orders received by
     a Fund's Transfer agent from dealers, brokers or other service providers
     after the NAV for the day is determined will receive that same day's NAV if
     the orders were received by the dealers, brokers or service providers from
     their customers prior to 4:00 p.m. and were transmitted to and received by
     the transfer agent prior to 8:00 a.m. Eastern time on the next day. A
     Fund's investments are valued based on market value, or where market
     quotations are not readily available, based on fair value as determined in
     good faith by the Fund's board.

SELLING SHARES

     You may sell shares at any time.  Your shares will be sold at the next NAV
     calculated after your order is accepted by the Fund's transfer agent.  Any
     certificates representing Fund shares being sold must be returned with your
     redemption request.  Your order will be processed promptly and you will
     generally receive the proceeds within a week.

     Before selling recently purchased shares, please note that if the Fund has
     not yet collected payment for the shares you are selling, it may delay
     sending the proceeds for up to fifteen days.

WRITTEN SELL ORDER

     Some circumstances require written sell orders, along with signature
     guarantees.  These include:

     .  amounts of $100,00 or more

     .  amounts of $1,000 or more on accounts whose address has been changed
        within the last 30 days

     .  requests to send the proceeds to a payee or address different than what
        is on our records

     A SIGNATURE GUARANTEE helps protect against fraud.  You can obtain one from
     most banks or securities dealers but not from a notary public.  Please call
     us to ensure that your signature guarantee will be processed correctly.

EXCHANGE PRIVILEGE
    
     You can exchange from one Class I Galileo Fund into another.  You can
     request your exchange in writing or by phone. Be sure to read the current
     prospectus for any Fund into which you are exchanging. Any new account
     established through an exchange will have the same privileges as your
     original account (as long as they are available).      

THIRD-PARTY TRANSACTIONS

     You may buy and redeem Fund shares through certain broker-dealers and
     financial organizations and their authorized intermediaries.  If purchases
     and redemptions of Fund shares are arranged and settlement is made at an
     investors election through a registered broker-dealer other than the Fund's
     distributor, that broker-dealer may, at its discretion, charge a fee for
     that service.

                                       51

ACCOUNT STATEMENTS

     Every Fund investor automatically receives regular account statements.  You
     will also be sent a yearly statement detailing the tax characteristics of
     any dividends and distributions you have received.

GENERAL POLICIES

     For any Fund, if your account falls below $25,000 as a result of
     redemptions and or exchanges for six months or more, the Fund may close
     your account and send you the proceeds upon 60 days' written notice.

     Unless you decline telephone privileges on your New Account Form, you may
     be responsible for any fraudulent telephone order as long as the Transfer
     Agent takes reasonable measures to verify the order.
    
     Each Fund restricts excessive trading (usually defined as more than four
     exchanges out of the Fund within a calendar year).  You are limited to one
     exchange of shares in the same Fund during any 15-day period except
     for the International Equities Fund, 401(k) and other group retirement
     accounts, investors who purchase shares through certain broker-dealers and
     asset allocation accounts managed by the Adviser or an affiliate. Each Fund
     reserves the right to:      

     .  refuse any purchase or exchange request that could adversely affect a
        Fund or its operations, including those from any individual or group
        who, in the Fund's view, are likely to engage in excessive trading

     .  change or discontinue its exchange privilege, or temporarily suspend
        this privilege during unusual market conditions

     .  delay sending out redemption proceeds for up to seven days (generally
        applies only in cases of very large redemptions, excessive trading or
        during unusual market conditions)

Large Redemption Amounts
    
Each Fund also reserves the right to make a "redemption in kind" - payment in 
portfolio securities rather than cash - if the amount you are redeeming in any 
90-day period is large enough to affect Fund operations (for example, if it 
equals more than $250,000 or represents more than 1% of the Fund's assets).

DISTRIBUTIONS AND TAXES

     The amount of dividends of net investment income and distributions of net
     realized long and short-term capital gains payable to shareholders will be
     determined separately for each Fund.  Dividends from the net investment
     income of the Emerging Markets Income Fund will be declared and paid
     monthly.  Dividends from the net investment income of each other Fund will
     be declared and paid annually. The Funds will distribute any net realized
     long or short-term capital gains at least annually.  Your distributions
     will be reinvested in the fund unless you instruct the fund otherwise.
     There are no fees or sales charges on reinvestments.

     In any fiscal year in which the Funds qualify as regulated investment
     companies and distribute to shareholders all of their net investment income
     and net capital gains, the Funds are relieved of Federal income tax.

     Generally, all dividends and capital gains are taxable whether they are
     reinvested or received in cash - unless you are exempt from taxation or
     entitled to tax deferral.  Capital gains distributions may be taxable at
     different rates depending on the length of time a Fund has held the assets
     sold.  Early each year, you will be notified as to the amount and Federal
     tax status of all distributions paid during the prior year.  Distributions
     may also be subject to state or local taxes.  The tax treatment of
     redemptions from a retirement plan account may differ from redemptions from
     an ordinary shareholder account.  If you redeem shares of a Fund or
     exchange them for shares of another Fund, any gain on the transaction may
     be subject to tax.  You must provide the Funds with a correct taxpayer
     identification number (generally your Social Security Number) and certify
     that you are not subject to backup withholding.  If you fail to do so, the
     IRS can require the Funds to withhold 31% of your taxable distributions and
     redemptions.  Federal law also requires the Funds to withhold 30% or the
     applicable tax treaty rate from dividends paid to nonresident alien, non-
     U.S. partnership and non-U.S. corporation shareholder accounts.

     This is a brief summary of some of the tax laws that affect your investment
     in the Fund.  Please see the Statement of Additional Information and your
     tax adviser for further information.

FINANCIAL HIGHLIGHTS

          The financial highlights table is intended to help you understand the
          Fund's financial performance for the fiscal years indicated. Certain
          information reflects financial results for a single Fund share. "Total
          return" shows how much your investment in the Institutional Class
          shares of the Fund would have increased (or decreased) during each
          period, assuming you had reinvested all dividends and distributions.
          These figures have been audited by Deloitte & Touche LLP, whose
          report, along with Company's financial statements, are included in the
          annual report, which is available upon request.

          results.
     /2/  Annualized.
     /3/  The Adviser has voluntarily agreed to reduce its fee, or to pay the
          operating expenses of the Fund, to the extent necessary to limit
          ordinary operating expenses of the Fund to 1.20% of net assets through
          December 31, 1998. Had such action not been taken, total annualized
          operating expenses for the period November 3, 1997 (commencement of
          operations) through October 31, 1998 would have been 1.51% of average
          net assets.

FINANCIAL HIGHLIGHTS

          The financial highlights table is intended to help you understand the
          Fund's financial performance for the fiscal years indicated. Certain
          information reflects financial results for a single Fund share. "Total
          return" shows how much your investment in the Institutional Class
          shares of the Fund would have increased (or decreased) during each
          period, assuming you had reinvested all dividends and distributions.
          These figures have been audited by Deloitte & Touche LLP, whose
          report, along with Company's financial statements, are included in the
          annual report, which is available upon request.

                INVESTMENT OBJECTIVES AND PRINCIPAL STRATEGIES
- --------------------------------------------------------------------------------
 
The Fund is affected by changes in the economy, or in securities and other
markets. There is also the possibility that investment decisions the Adviser
makes will not accomplish what they were designed to achieve or that companies
in which the Fund invests will have disappointing performance or not pay their
debts.

</TABLE>

Under adverse market conditions, the Fund could invest some or all of its assets
in money market securities.  Although the Fund would do this only in seeking to
avoid losses, it could have the effect of reducing the benefit from any upswing
in the market.

                               PRINCIPAL RISKS 
- --------------------------------------------------------------------------------
Risk is the chance that you will lose money on your investment or that it will
not earn as much as you expect. In general, the greater the risk, the more money
your investment can earn for you -- and the more you can lose. Since shares of 
the Fund represent an investment of securities with fluctuating market prices,
the value of Fund shares will vary as the Fund's portfolio securities increase
or decrease. Therefore, the value of an investment in the Fund could go down as
well as up. All investments are subject to:
     
 .  MARKET RISK      
 
   There is the possibility that the returns from the types of securities in
   which the Fund invests will underperform returns from the various general
   securities markets or different asset classes. Different types of securities
   tend to go through cycles of outperformance and underperformance in
   comparison to the general securities markets.
 
 .  SECURITIES SELECTION RISK
 
   There is the possibility that the specific securities held in the Fund's
   portfolio will underperform other funds in the same asset class or benchmarks
   that are representative of the general performance of the asset class because
   of the portfolio manager's choice of securities.
 
 .  PRICE VOLATILITY
 
   There is the possibility that the value of the Fund's portfolio will change
   as the prices of its investments go up or down. Although stocks offer the
   potential for greater long-term growth than most fixed income securities,
   stocks generally have higher short-term volatility.
     
The Fund may also be subject to the following risks:      
 
 .  LIQUIDITY RISK

   There is the possibility that the Fund may lose money or be prevented from
   earning capital gains if it cannot sell a security at the time and price
   that is most beneficial to the Fund. The Fund is subject to liquidity risk
   because it invests primarily in securities of medium sized companies.
 
 .  FOREIGN INVESTING RISK
     
   There is the likelihood that foreign investments may be riskier than U.S.
   investments because of a lack of political stability, foreign controls on
   investment and currency exchange rates, fluctuations in currency exchange
   rates, withholding taxes, and lack of adequate company information. The Fund
   is subject to foreign investing risk because it may invest a portion of its
   assets in foreign company securities. In addition, because foreign securities
   generally are denominated and pay dividends or interest in foreign
   currencies, and the Fund may hold various foreign currencies, the value of
   the net assets of the Fund as measured in U.S. dollars can be affected
   favorably or unfavorably by changes in exchange rates.

<PAGE>
 
                                PRINCIPAL RISKS
- --------------------------------------------------------------------------------

Because the Fund is non-diversified for 1940 Act purposes, it may invest more
than 5% of its total assets in the securities of any one issuer. Consequently,
its exposure to credit and market risks associated with that issuer is
increased.

Your investment is not a bank deposit, and it is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency.

                              PERFORMANCE SUMMARY
- --------------------------------------------------------------------------------
     
The two tables below show the Fund's annual returns and its long-term
performance with respect to its Institutional Class shares (Class N shares of
the Fund commenced operations on March 1, 1999). The first table shows you how
the Fund's performance has varied from year to year. The second compares the
Fund's performance over time to that of a broad-based securities index. Both
tables assume reinvestment of dividends and distributions. The performance
information includes performance of the predecessor limited partnership, which
was managed by a predecessor of TCW Funds Management, Inc. using the same
investment strategy as the Fund. The performance of the partnership was
calculated using performance standards applicable to private investment
partnerships which take into account all elements of total return and reflect
the deduction of all fees and expenses of operation. The predecessor limited
partnership, was not registered under the Investment Company Act of 1940 ("1940
Act") and therefore, was not subject to certain investment restrictions imposed
by the 1940 Act and Subchapter M of the Internal Revenue Code of 1986, as
amended. If the limited partnership had been registered under the 1940 Act its
performance could have been adversely affected. As with all mutual funds, past
performance is not a prediction of future results.

This Example shows what you could pay in expenses over time. It uses the same
hypothetical conditions other funds use in their prospectuses: $10,000 Initial
Investment, 5% total return each year and no changes in expenses. The figures
shown would be the same whether or not you sold your shares at the end of a
period. Because actual return and expenses will be higher or lower, the Example
is for comparison purposes only.

                  TCW GALILEO AGGRESSIVE GROWTH EQUITIES FUND

INVESTMENT OBJECTIVES/APPROACH
- ------------------------------

CONCEPTS TO UNDERSTAND
- ----------------------
Emerging growth companies are companies that are likely to show rapid growth 
through reinventing an existing industry or pioneering a new industry.

    
The Fund seeks long-term capital appreciation. To pursue this goal, the Fund
anticipates that at least 65% of the value of its total assets will be invested
in equity securities (except when maintaining a temporary defensive position) of
issuers, which are characterized as "growth" companies according to criteria
established by the Adviser. These securities include common and preferred stock
and convertible securities. In managing the Fund's investments, the Adviser will
focus on emerging companies that exhibit this characteristic.      

The Adviser utilizes a "bottom-up" approach to identify securities for
investment. First, the Adviser uses quantitative and qualitative criteria to
screen companies. The Adviser then subjects companies that make it through this
screening process to fundamental analysis, which generally looks for at least
some of the following factors:

 .  a demonstrated record of consistent earnings growth or the potential to grow
   earnings
 .  an ability to earn an attractive return on equity
 .  a price/earnings ratio which is less than the Adviser's internally estimated
   three-year earnings growth rate
 .  a large and growing market share
 .  a strong balance sheet
 .  significant ownership interest by management and a strong management team.

MAIN RISKS
- ----------

The Fund holds primarily stocks, which may go up or down in value, sometimes
rapidly and unpredictably. Although stocks offer the potential for greater long-
term growth than most fixed income securities, stocks generally have higher
short-term volatility. In addition, the Fund may hold convertible debt
securities. Many convertible debt securities are rated below investment grade
and are considered speculative by rating agencies as to repayment of principal
and interest.

The primary risks affecting this Fund are "price volatility" and "liquidity
risk." PRICE VOLATILITY refers to the possibility that the value of the Fund's
portfolio will change as the prices of its investments go up or down. This Fund
may be subject to greater price volatility than funds that invest in the
securities of larger companies. LIQUIDITY RISK refers to the possibility that
the Fund may lose money or be prevented from earning capital gains if it cannot
sell securities at the time and price that is most beneficial to the Fund.
Because the securities of medium-sized companies may be less liquid than the
securities of large-sized companies, the Fund may be susceptible to liquidity
risk more than funds that invest in the securities of large-sized companies. In
addition, the Fund may be subject to liquidity risk because it may invest in
debt instruments rated below investment grade.
    
The Fund seeks to earn additional income by making loans of its portfolio
securities to brokers, dealers and other financial institutions. The loans will
be secured at all times by cash and liquid high grade debt obligations. As with
any extension of credit, there are risks of delay in recovery and in some cases
even loss of rights in the collateral should the borrower fail financially. The
Fund may engage in active portfolio management which may result in increased
Fund transaction expenses and have tax consequences such as increased realized
gains for investors.

RISK CONSIDERATIONS
- -------------------

GENERAL INVESTMENT RISK
- -----------------------

Since shares of the fund represent an Investment in securities with fluctuating 
market prices, the value of Fund shares will vary as the value of the Fund's 
portfolio securities increases or decreases. Therefore, the value of an 
investment in the Fund could go down as well as up.


Please consider the following risks before investing in the Fund.

Various market risks can affect the price or liquidity of an issuer's
securities. Adverse events occurring with respect to an issuer's performance or
financial position can depress the value of the issuer's securities. The
liquidity in a market for a particular security will affect its value and may be
affected by factors relating to the issuer, as well as the depth of the market
for that security. Other market risks that can affect value include a market's
current attitudes about types of securities, market reactions to political or
economic events, and tax and regulatory effects (including lack of adequate
regulations for a market or particular type of instrument). Market restrictions
on trading volume can also affect price and liquidity.

Prices of many securities tend to be more volatile in the short-term. Therefore,
an investor who trades frequently or redeems in the short-term is more likely to
incur loss than an investor who holds investments for the longer term. The fewer
the number of issuers in which a Fund invests, the greater the potential
volatility of its portfolio.
     
The Adviser may temporarily invest up to 100% of the Fund's assets in high
quality, short-term money market instruments if it believes adverse economic or
market conditions, such as excessive volatility or sharp market declines,
justify taking a defensive investment posture. If the Fund attempts to limit
investment risk by temporarily taking a defensive investment position, it may be
unable to pursue its investment objective during that time, and it may miss out
on some or all of an upswing in the securities markets.     

                                       12

RISK CONSIDERATIONS
- -------------------

FOREIGN INVESTING
- -----------------

Investment in foreign securities involves special risks in addition to the usual
risks inherent in domestic investments. These include: political or economic
instability; the unpredictability of international trade patterns; the
possibility of foreign governmental actions such as expropriation,
nationalization or confiscatory taxation; the imposition or modification of
foreign currency or foreign investment controls; the imposition of withholding
taxes on dividends, interest and gains; price volatility; and fluctuations in
currency exchange rates.
    
As compared to U.S. companies, foreign issuers generally disclose less financial
and other information publicly and are subject to less stringent and less
uniform accounting, auditing and financial reporting standards. Foreign
countries typically impose less thorough regulations on brokers, dealers, stock
exchanges, insiders and listed companies than does the U.S., and foreign
securities markets may be less liquid and more volatile than domestic markets.
Investment in foreign securities involves higher costs than investment in U.S.
securities, including higher transaction and custody costs as well as the
imposition of additional taxes by foreign governments. In addition, security
trading practices abroad may offer less protection to investors such as the
Fund. Settlement of transactions in some foreign markets may be delayed or may
be less frequent than in the U.S., which could affect the liquidity of the
Fund's portfolio. Also, it may be more     

                                       13
<PAGE>
 
difficult to obtain and enforce legal judgments against foreign corporate
issuers than against domestic issuers and it may be impossible to obtain and
enforce judgments against foreign governmental issuers.

Because foreign securities generally are denominated and pay dividends or
interest in foreign currencies, and the Fund may hold various foreign currencies
from time to time, the value of the net assets of the Fund as measured in United
States dollars can be affected favorably or unfavorably by changes in exchange
rates. Generally, currency exchange transactions will be conducted on a spot
(i.e., cash) basis at the spot rate prevailing in the currency exchange market.
The cost of currency exchange transactions will generally be the difference
between the bid and offer spot rate of the currency being purchased or sold. In
order to protect against uncertainty in the level of future foreign currency
exchange rates, the Fund is authorized to enter into certain foreign currency
futures and forward contracts. However, it is not obligated to do so, and,
depending on the availability and cost of these devices, the Fund may be unable
to use foreign currency futures and forward contracts to protect against
currency uncertainty. Please see Statement of Additional Information for further
information. 
    
The forward currency market for the purchase or sale of U.S. dollars in most
countries is not highly developed, and in certain countries, there may be no
such market. If a devaluation of a currency is generally anticipated, the Fund
may not be able to contract to sell the currency at an exchange rate more
advantageous than that which would prevail after the anticipated amount of
devaluation, particularly in regards to forward contracts for local Latin
American currencies in view of the relatively small, inactive or even non-
existent market for these contracts. In the event the Fund holds securities
denominated in a currency that suffers a devaluation, the Fund's net asset
values will suffer corresponding reductions. In this regard, in December 1994,
the Mexican government determined to allow the Mexican peso to trade freely
against the U.S. dollar rather than within a controlled band, which action
resulted in a significant devaluation of the Mexican peso against the dollar.
Further, in July 1997, the Thai and Philippine governments allowed the baht and
peso, respectively, to trade freely against the United States dollar resulting
in a sharp devaluation of both currencies, and in 1998 Russia did the same,
causing a sharp devaluation of the ruble.

RISK CONSIDERATIONS
- -------------------

FIXED INCOME SECURITIES
- -----------------------

Fixed income securities are subject to various risks. The two primary (but not
exclusive) risks affecting fixed income instruments are "credit risk" and
"interest rate risk." These risks can affect a security's price volatility to
varying degrees, depending upon the nature of the instrument. In addition, the
depth and liquidity of the market for an individual or class of fixed income
security can also affect its price and, hence, the market value of the Fund.


"CREDIT RISK" refers to the likelihood that an issuer will default in the
payment of principal and/or interest on an instrument. Financial strength and
solvency of an issuer are the primary factors influencing credit risk. In
addition, lack of or inadequacy of collateral or credit enhancements for a fixed
income security may affect its credit risk. Credit risk of a security may change
over its life, and securities which are rated by rating agencies are often
reviewed and may be subject to downgrade.

The Fund may invest in convertible securities rated below investment grade. Debt
securities that are rated below investment grade are considered to be
speculative; they are also commonly known as "junk" bonds. Generally, lower-
rated debt securities provide a higher yield than higher rated debt securities
of similar maturity but are subject to greater credit risk than higher rated
securities of similar maturity. Such securities are regarded as predominantly
speculative with respect to the issuer's continuing ability to meet principal
and interest 

                                       15
<PAGE>
 
payments. Because investment in lower quality securities involves greater
investment risk, achievement of the Fund's investment objective will be more
dependent on the Adviser's analysis than would be the case if the Fund were
investing in higher quality bonds. In addition, lower quality securities may be
more susceptible to real or perceived adverse economic and individual corporate
developments than would investment grade bonds. Moreover, the secondary trading
market for lower quality securities may be less liquid than the market for
investment grade bonds. This potential lack of liquidity may make it more
difficult for the Adviser to value accurately certain portfolio securities.

"INTEREST RATE RISK" refers to the risks associated with market changes in
interest rates. Interest rate changes may affect the value of a fixed income
security directly (especially in the case of fixed rate securities) and
indirectly (especially in the case of adjustable rate securities). In general,
rises in interest rates will negatively impact the price of fixed rate
securities and falling interest rates will have a positive effect on price. The
degree to which a security's price will change as a result of changes in
interest rates is measured by its "duration." For example, the price of a bond
with a 5 year duration would be expected under normal market conditions to
decrease 5% for every 1% increase in interest rates. Generally, securities with
longer maturities have a greater duration and thus are subject to greater price
volatility from changes in interest rates. Adjustable rate instruments also
react to interest rate changes in a similar manner although generally to a
lesser degree (depending, however, on the characteristics of the reset terms,
including the index chosen, frequency of reset and reset caps or floors, among
other things).

                                       16
<PAGE>
 
RISK CONSIDERATIONS
- -------------------

NON-DIVERSIFIED STATUS
- ----------------------

The Fund is non-diversified for 1940 Act purposes and as such may invest a
larger percentage of its assets in individual issuers than a diversified
investment company. In this regard, the Fund is not subject to the general
limitation that it not invest more than 5% of its total assets in the securities
of any one issuer. To the extent the Fund makes investments in excess of 5% of
its assets in a particular issuer, its exposure to credit and market risks
associated with that issuer is increased. However, the Fund's investments will
be limited so as to qualify for the special tax treatment afforded "regulated
investment companies" under the Internal Revenue Code of 1986, as amended.

                                       17
<PAGE>
 
RISK CONSIDERATIONS
- -------------------

YEAR 2000
- ---------
    
The investment advisory and management services provided by the Adviser and the
services provided to shareholders by the Transfer Agent depend on the smooth
functioning of their computer systems. Many computer software systems in use
today cannot recognize the year 2000, but revert to 1900 or some other date, due
to the manner in which dates were encoded and calculated. That failure could
have a negative impact on the handling of securities trades, pricing and account
services. The Adviser and the Transfer Agent have been actively working on
necessary changes to their own computer systems to prepare for the year 2000 and
expect that their systems will be adapted for year 2000 compliance before that
date, but there can be no assurance that they will be successful, or that
interaction with other non-complying computer systems will not impair their
services at that time. The Adviser has been, and is currently, in contact with
each of its External Service Providers to evaluate their readiness for the year
2000. The Adviser has requested each of its External Service Providers to either
(i) prepare a description of its process for identifying date sensitive areas,
its approach for implementing changes, its testing methodology, along with its
timetable for completion, or (ii) certify as to its year 2000 compliance.      

In addition, it is possible that the markets for securities in which the Fund
invests may be negatively affected by computer failures throughout the financial
services industry commencing January 1, 2000. Improperly functioning trading
systems may result in settlement problems. In addition, corporate and
governmental data processing errors may result in production problems for
individual companies and create overall economic uncertainties. Earnings of
individual issuers will be affected by remediation

                                       18
<PAGE>
 
costs which may be substantial. Individual firms may further experience
disruptions to their business due to the failure of their counterparts to
address year 2000 problems, or could experience further disruption to the
economy at large, which could adversely affect corporate earnings generally and
the value of their securities. Accordingly, the Fund's portfolio investments may
be negatively affected.

                                       19
<PAGE>
 
RISK CONSIDERATIONS
- -------------------

EUROPEAN ECONOMIC AND MONETARY UNION
- ------------------------------------
    
The Fund may invest in European countries that have agreed to enter into the
European Monetary Union (EMU). EMU is an effort by certain European countries
to, among other things, reduce barriers between countries and eliminate
fluctuations in their currencies. Among other things, EMU establishes a single
European currency (the euro), which was introduced on January 1, 1999 and is
expected to replace the existing national currencies of all initial EMU
participants by July 1, 2002. Upon introduction of the euro, certain securities
(beginning with government and corporate bonds) have been redonominated in the
euro and, thereafter trade and make dividend and other payments only in 
euros.     
    
Like other investment companies and business organizations, including the
companies in which the Fund invests, the Fund could be adversely affected: (i)
if the euro, or EMU as a whole does not take affect as planned; (ii) if a
participating country withdraws from EMU; or (iii) if the computing, accounting
and trading systems used by the Fund's service providers, or by other business
entities with which the Fund or its service providers do business, are not
capable of recognizing the euro as a distinct currency at the time of, and
following euro conversion.

ADVISORY AGREEMENT

The Company and the Adviser have entered into an Investment Advisory and
Management Agreement (the "Advisory Agreement"), under the terms of which the
Company has employed the Adviser to manage the investment of its assets, to
place orders for the purchase and sale of its portfolio securities, and to be
responsible for overall management of the Company's business affairs, subject to
control by the Board of Directors of the Company. The Adviser also pays certain
costs of marketing the Fund, including sales personnel compensation, from
legitimate profits from its investment advisory fees and other resources
available to it. 

                                       21

Under the Advisory Agreement, the Fund pays to the Adviser as compensation for
the services rendered, facilities furnished, and expenses paid by it the
following fees:

The Advisory Agreement provides that the Adviser shall not be liable for any
error of judgment or mistake of law or for any loss suffered by the Fund in
connection with the matters to which the agreement relates, except a loss
resulting from willful misfeasance, bad faith or gross negligence on the part of
the Adviser in the performance of its duties or from reckless disregard by the
Adviser of its duties under the agreement.

MULTIPLE CLASS STRUCTURE
- ------------------------
The Fund currently offers two classes of shares, Institutional Class shares and
Class N shares. Shares of each class of the Fund represent an equal pro rata
interest in the Fund and generally gives you the same voting, dividend,
liquidation, and other rights. The Institutional Class shares are offered at the
current net asset value. The Class N shares are also offered at the current net
asset value, but will be subject to fees imposed under a distribution plan
("Distribution Plan") adopted pursuant to Rule 12b-1 under the Investment
Company Act of 1940, as amended. Pursuant to the Distribution Plan, the Fund
compensates the Fund's distributor at a rate equal to 0.25% of the average daily
net assets of the Fund attributable to its Class N shares for distribution and
related services. Because these fees are paid out of the Fund's Class N assets
on an on-going basis, over time, these fees will increase the cost of your
investment and may cost you more than paying other types of sales charges.

ACCOUNT POLICIES AND SERVICES
- -----------------------------

BUYING SHARES
    
You pay no sales charges to invest in the Fund. Your price for Fund shares is
the Fund's net asset value per share (NAV) which is calculated as of the close
of trading on the New York Stock Exchange (usually 4:00 p.m. Eastern time) every
day the exchange is open. Your order will be priced at the next NAV calculated
after your order is accepted by the Fund. Orders received by the Fund's Transfer
Agent from dealers, brokers or other service providers after the NAV for the day
is determined, will receive that same day's NAV if the orders were received by
the dealers, brokers or service providers from their customers prior to 4:00
p.m. and were transmitted to and received by the Transfer Agent prior to 8:00
a.m. Eastern time on the next day. The Fund's investments are valued based on
market value, or where market quotations are not readily available, based on
fair value as determined in good faith by the Fund pursuant to procedures
established by the Fund's board.

SELLING SHARES

You may sell shares at any time. Your shares will be sold at the next NAV
calculated after your order is accepted by the Fund's Transfer Agent. Any
certificates representing Fund shares being sold must be returned with your
redemption request. Your order will be processed promptly, and you will
generally receive the proceeds within a week.

Before selling recently purchased shares, please note that if the Fund has not
yet collected payment for the shares you are selling, it may delay sending the
proceeds for up to fifteen days.

WRITTEN SELL ORDER

Some circumstances require written sell orders, along with signature guarantees.
These include:

     .  amounts of $100,000 or more

     .  amounts of $1,000 or more on accounts whose address has been changed
        within the last 30 days

     .  requests to send the proceeds to a payee or address different than what
        is on our records

A SIGNATURE GUARANTEE helps protect against fraud. You can obtain one from most
banks or securities dealers but not from a notary public. Please call us to
ensure that your signature guarantee will be processed correctly.

EXCHANGE PRIVILEGE

You can exchange from one Class N Galileo Fund into another. You can request
your exchange in writing or by phone. Be sure to read the current prospectus for
any Fund into which you are exchanging. Any new account established through an
exchange will have the same privileges as your original account (as long as they
are available).

THIRD PARTY TRANSACTIONS

You may buy and redeem Fund shares through certain broker-dealers and financial
organizations and their authorized intermediaries. If purchases and redemptions
of Fund shares are arranged and settlement is made at an investor's election
through a registered broker-dealer, other than the Fund's distributor, that
broker-dealer may, at its discretion, charge a fee for that service.

                                       24

ACCOUNT STATEMENTS

Every Galileo investor automatically receives regular account statements. You
will also be sent a yearly statement detailing the tax characteristics of any
dividends and distributions you have received.

GENERAL POLICIES

If your account falls below $1,000 as a result of redemptions and or exchanges
for six months or more, the Fund may close your account and send you the
proceeds upon 60 days' written notice.

LARGE REDEMPTION AMOUNTS
- ------------------------

The Fund also reserves the right to make a "redemption in kind" - payment in
portfolio securities rather than cash - if the amount you are redeeming in any
90-day period is large enough to affect Fund operations (for example, if it
equals more than $250,000 or represents more than 1% of the Fund's assets).

Unless you decline telephone privileges on your New Account Form, you may be
responsible for any fraudulent telephone order as long as the Transfer Agent
takes reasonable measures to verify the order.

The Fund restricts excessive trading (usually defined as more than four
exchanges out of the Fund within a calendar year). You are limited to one
exchange of shares in the Fund during any 15-day period except investors in
401(k) and other group retirement accounts, investors who purchase shares
through certain broker dealers, and asset allocation accounts managed by the
Adviser or an affiliate. The Fund reserves the right to:

     .  refuse any purchase or exchange request that could adversely affect the
        Fund or its operations, including those from any individual or group
        who, in the Fund's view, are likely to engage in excessive trading

     .  change or discontinue its exchange privilege, or temporarily suspend
        this privilege during unusual market conditions

     .  delay sending out redemption proceeds for up to seven days (generally
        applies only in cases of very large redemptions, excessive trading or
        during unusual market conditions).

DISTRIBUTIONS AND TAXES
- -----------------------

The amount of dividends of net investment income and distributions of net
realized long and short-term capital gains payable to shareholders will be
determined separately for the Fund. Dividends from the net investment income of
the Fund will be declared and paid annually. The Fund will distribute any net
realized long or short-term capital gains at least annually. Your distributions
will be reinvested in the Fund unless you instruct the Fund otherwise. There are
no fees or sales charges on reinvestments.

In any fiscal year in which the Fund qualifies as a regulated investment company
and distributes to shareholders all of its net investment income and net capital
gains, the Fund is relieved of Federal income tax.

Generally, all dividends and capital gains are taxable whether they are
reinvested or received in cash - unless you are exempt from taxation or entitled
to tax deferral. Capital gains distributions may be taxable at different rates
depending on the length of time the Fund has held the assets sold. Early each
year, you will be notified as to the amount and Federal tax status of all
distributions paid during the prior year. Distributions may also be subject to
state or local taxes. The tax treatment of redemptions from a retirement plan
account may differ from redemptions from an ordinary shareholder account. If you
redeem shares of the Fund or exchange them for shares of another Fund, any gain
on the transaction may be subject to tax. You must provide the Fund with a
correct taxpayer identification number (generally your Social Security Number)
and certify that you are not subject to backup withholding. If you fail to do
so, the IRS can require the Fund to withhold 31% of your taxable distributions
and redemptions. Federal law also requires the Fund to withhold 30% or the
applicable tax treaty rate from dividends paid to nonresident alien, non-U.S.
partnership and non-U.S. corporation shareholder accounts.

This is a brief summary of some of the tax laws that affect your investment in
the Fund. Please see the Statement of Additional Information and your tax
adviser for further information.

FINANCIAL HIGHLIGHTS
- --------------------

The financial highlights table is intended to help you understand the Fund's
financial performance for the fiscal years indicated. Certain information
reflects financial results for a single Fund share. "Total return" shows how
much your investment in the Institutional Class shares of the Fund would have
increased (or decreased) during each period, assuming you had reinvested all
dividends and distributions (Class N shares of the Fund commenced operations on
March 1, 1999). These figures have been audited by Deloitte & Touche LLP, whose
report, along with Company's financial statements, are included in the annual
report, which is available upon request.

INVESTMENT OBJECTIVES AND PRINCIPAL STRATEGIES
- --------------------------------------------------------------------------------
 
The Fund is affected by changes in the economy, or in securities and other
markets. Additionally, changes in interest rates will affect not only the
current return on the Fund, but the value of the capital investment will most
likely fluctuate up or down. There is also the possibility that investment
decisions the Adviser makes will not accomplish what they were designed to
achieve or that companies in which the Fund invests will have disappointing
performance or not pay their debts.

Under adverse market conditions, the Fund could invest some or all of its assets
in money market securities.  Although the Fund would do this only when seeking
to avoid losses, it could have the effect of reducing the benefit from any
upswing in the market.

PRINCIPAL RISKS
- -------------------------------------------------------------------------------
 
Risk is the chance that you will lose money on your investment or that it will
not earn as much as you expect. In general, the greater the risk, the more money
your investment can earn for you and the more you can lose. Since shares of the
Fund represent an investment in securities with fluctuating market prices, the
value of fund shares will vary as the value of the Fund's portfolio securities
increases or decreases in value. Therefore, the value of an investment in the
Fund could go down as well as up. All investments are subject to:
    
 .    MARKET RISK     
 
     There is the possibility that the returns from the types of securities in
     which the Fund invests will underperform returns from the various general
     securities markets or different asset classes. Different types of
     securities tend to go through cycles of outperformance and underperformance
     in comparison to the general securities markets.

 .    SECURITIES SELECTION RISK
 
     There is the possibility that the specific securities held in the Fund's
     portfolio will underperform the other funds in the same asset class or will
     underperform benchmarks that are representative of the general performance
     of the asset class because of the portfolio manager's choice of securities.
     
Because the Fund is a fixed-income fund. The Fund is subject (in varying
degrees) to the following additional risks:
 
 .    CREDIT RISK
 
     There is the possibility that the Fund could lose money if an issuer is
     unable to meet its financial obligations such as the payment of principal
     and/or interest on an instrument, or goes bankrupt. The Fund is subject to
     credit risk because it invests to some degree in below investment grade
     fixed income securities.
     
 .    INTEREST RATE RISK
 
     There is the possibility that the value of the Fund's portfolio investments
     may fall since fixed income securities generally fall in value when
     interest rates rise. The longer the term of a fixed income instrument, the
     more sensitive it will be to fluctuations in value from interest rate
     changes. Changes in interest rates may have a significant effect on the
     Fund because it may hold securities with long terms to maturity.
     
     In the case of mortgage-backed securities, rising interest rates tend to
     extend the term to maturity of the securities, making them even more
     susceptible to interest rate changes. When interest rates drop, not only
     can the value of fixed income securities drop, but the yield can drop,
     particularly where the yield on the fixed income securities is tied to
     changes in interest rates, such as adjustable mortgages. Also when interest
     rates drop, the holdings of mortgage-backed securities by the Fund can
     reduce returns if the owners of the underlying mortgages pay off their
     mortgages sooner than anticipated since the funds prepaid will have to be
     reinvested at the then lower prevailing rates. This is known as prepayment
     risk. When interest rates rise, the holdings of mortgage-backed securities
     by the Fund can reduce returns if the owners of the underlying mortgages
     pay off their mortgages later than anticipated. This is known as extension
     risk. 

                                       4
<PAGE>
 
- -------------------------------------------------------------------------------
PRINCIPAL RISKS
- -------------------------------------------------------------------------------
 
 .    JUNK BONDS
 
     These bonds are speculative in nature. They are usually issued by companies
     without long tract records of sales and earnings, or by those companies
     with questionable credit strength. These bonds are considered "below
     investment grade." The Fund may invest in debt instruments rated below
     investment grade.
     
 .    FOREIGN INVESTING RISK
     
     There is the likelihood that foreign investments may be riskier than U.S.
     investments because of a lack of political stability, foreign controls on
     investment and currency exchange rates, fluctuations in currency exchange
     rates withholding taxes, and a lack of adequate company information. The
     Fund is subject to foreign investing risk because it may invest a portion
     of its assets in foreign company securities. If it invests in "emerging
     markets," and it may, the risk is even more pronounced. In addition,
     because foreign securities generally are denominated and pay dividends or
     interest in foreign currencies, and the Fund may hold various foreign
     currencies, the value of the net assets of the Fund as measured in U.S.
     dollars can be affected favorably or unfavorably by changes in exchange
     rates.     
     
 .    LIQUIDITY RISK
 
     There is the possibility that the Fund may lose money or be prevented from
     earning capital gains if it cannot sell a security at the time and price
     that is most beneficial to the Fund. The Fund is subject to liquidity risks
     because it invests in high yield bonds, mortgage-backed securities or
     foreign or emerging markets securities, which have all experienced periods
     of illiquidity.
         
The Fund may be more susceptible to some of these risks than others, as noted in
the description of the Fund. A more detailed explanation of these risks is
presented under the "Risk Considerations" section at page 11.      
    
Your investment is not a bank deposit, and it is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE SUMMARY
- -------------------------------------------------------------------------------
     
The two tables below show the Fund's annual returns and its long-term
performance with respect to its Institutional Class shares (Class N shares of
the Fund commenced operations on March 1, 1999). The first table shows you how
the Fund's performance has varied from year to year. The second compares the
Fund's performance over time to that of a broad-based securities index. Both
tables assume reinvestment of dividends and distributions. The performance
information includes performance of the predecessor limited partnership, which
was managed by a predecessor of TCW Funds Management, Inc. using the same
investment strategy as the Fund. The performance of the partnership was
calculated using performance standards applicable to private investment
partnerships which take into account all elements of total return and reflect
the deduction of all fees and expenses of operation. The predecessor limited
partnership, was not registered under the Investment Company Act of 1940 ("1940
Act") and therefore, was not subject to certain investment restrictions imposed
by the 1940 Act and Subchapter M of the Internal Revenue Code of 1986, as
amended. If the limited partnership had been registered under the 1940 Act its
performance could have been adversely affected. As with all mutual funds, past
performance is not a prediction of future results.

Expense Example

This Example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other mutual funds.

This Example shows what you could pay in expenses over time. It uses the same
hypothetical conditions other funds use in their prospectuses: $10,000 initial
investment, 5% total return each year and no changes in expenses. The figures
shown would be the same whether or not you sold your shares at the end of a
period. Because actual return and expenses will be higher or lower, the Example
is for comparison purposes only.

LOGO      INVESTMENT OBJECTIVES/APPROACH
- ----------------------------------------

Concepts to understand
- ----------------------

Duration is often used to measure the potential volatility of a bond's price:
bonds with longer durations are more sensitive to changes in interest rates,
making them more volatile than bonds with shorter durations. Bonds with fixed
maturities have a readily determinable duration. Bonds with uncertain payment
schedules, such as mortgage-backed securities, which can be prepaid, have
durations which may vary or lengthen in certain interest rate environments,
making their values even more volatile than they were when acquired.
    
          The Fund seeks to provide maximum current income and achieve above
          average total return consistent with prudent investment management
          over a full market cycle.  To pursue this goal, it invests (except
          when maintaining a temporary defensive position) at least 65% of the
          value of its total assets in fixed income securities rated A or higher
          by Moody's and S&P. These securities include U.S. Government
          obligations, bonds, notes, debentures, mortgage-backed securities,
          asset-backed securities, foreign securities (government and 
          corporate), and other securities bearing fixed or variable interest
          rates of any maturity.    

          In managing the Fund's investments, the Adviser uses a controlled risk
          approach.  The techniques of this approach attempt to control the
          principal risk components of the fixed income markets.  These
          components include:

LOGO      MAIN RISKS
- --------------------

          The primary risks affecting this Fund are "credit risk," "interest
          rate risk" (including "extension risk" and "prepayment risk"),
          "foreign investing risk" and "liquidity risk."

          Credit risk refers to the likelihood that the Fund could lose money if
          an issuer is unable to meet its financial obligations, such as the
          payment of principal and/or interest on an instrument, or goes
          bankrupt.  This Fund invests primarily in high credit quality
          securities that have limited susceptibility to this risk.  A portion
          of the Fund's assets, however, will be invested in low credit quality
          securities that may make the Fund subject to greater credit risk,
          especially during periods of economic uncertainty or during economic
          downturns.  Debt securities that are rated below investment grade are
          considered to be speculative.  Securities rated below investment grade
          are also known as "junk" bonds.  Interest rate risk refers to the
          possibility that the value of the Fund's portfolio investments may
          fall since fixed income securities generally fall in value when
          interest rates rise.  The longer the term of a fixed income
          instrument, the more sensitive it will be to fluctuations in value
          from interest rate changes.  Changes in interest rates may have a
          significant effect on this Fund, because it may hold securities with
          long terms to maturity and mortgage-backed securities, including
          collateralized mortgage obligations and stripped mortgage securities.
          Its holding of mortgage-backed securities can reduce returns if the
          owners of the underlying mortgages pay off their mortgages sooner than
          anticipated when interest rates go down.  Because this Fund may invest
          in mortgage-backed securities, it may be subject to extension risk and
          prepayment risk, which are both a type of interest rate risk.
          Extension risk refers to the possibility that rising interest rates
          may cause owners of the underlying mortgages to pay off their
          mortgages at a slower than expected rate.  This particular risk may
          effectively change a security which was considered short or
          intermediate term into a long-term security. Long-term securities
          generally drop in value more dramatically in response to rising
          interest rates than short or intermediate-term securities.  Prepayment
          risk refers to the possibility that falling interest rates may cause
          owners of the underlying mortgages to pay off their mortgages at a
          faster than expected rate.  Because the Fund may invest a portion of
          its assets in foreign company securities, it may be subject to foreign
          investing risks.  Foreign investing risk refers to the likelihood

                                       9
<PAGE>
 
          that foreign investments may be riskier than U.S. investments because
          of many factors, some of which include:

          .  a lack of political or economic stability
            
          .  foreign controls on investment and changes in currency exchange 
             rates
            
          .  withholding taxes
            
          .  a lack of adequate company information

          The risks of foreign investing are even more pronounced if the Fund
          invests in emerging markets.  In addition, securities traded only
          through foreign markets may be more volatile and are often harder to
          sell. Volatility is a way to measure the changes in the price of a
          single security or an entire portfolio.  Large and frequent price
          changes indicate higher volatility, which generally indicates that
          there is a greater chance you could lose money over the short term.
          The Fund is also subject to foreign currency risk.  Because foreign
          securities are generally denominated and pay dividends or interest in
          foreign currencies, the value of the net assets of the Fund as
          measured in the United States dollars will be affected favorably or
          unfavorably by changes in exchange rates.  Liquidity risk refers to
          the possibility that the Fund may lose money or be prevented from
          earning capital gains if it cannot sell a security at the time and
          price that is most beneficial to the Fund.  Because the Fund invests
          in below grade fixed income securities, it is more susceptible to
          liquidity risks than funds that invest in higher quality investments.

          The Fund may invest some assets in options, futures and foreign
          currency futures, and forward contracts.  These practices are used
          primarily to hedge the Fund's portfolio, but may also be used to
          increase returns; however, such practices sometimes may reduce returns
          or increase volatility.

          The Fund seeks to earn additional income by making loans of its
          portfolio securities to brokers, dealers and other financial
          institutions.  The loans will be secured at all times by cash and
          liquid high grade debt obligations.  As with any extension of credit,
          there are risks of delay in recovery and in some cases even loss of
          rights in the collateral should the borrower fail financially.
    
          The Fund may engage in active portfolio management which may result in
          increased fund transaction expenses and have tax consequences such as
          increased realized gains.

General Investment Risk
- -----------------------
    
Since shares of the Fund represent an investment in securities with fluctuating 
market prices, the value of Fund shares will vary as the value of the Fund's 
portfolio securities increases or decreases. Therefore, the value of an 
investment in a Fund could go down as well as up. This is also true for funds 
that invest primarily in fixed income securities. High credit quality 
investments also react in value to interest rate changes.     

          Please consider the following risks before investing in the Fund.

          Various market risks can affect the price or liquidity of an issuer's
          securities.  Adverse events occurring with respect to an issuer's
          performance or financial position can depress the value of the
          issuer's securities.  The liquidity in a market for a particular
          security will affect its value and may be affected by factors relating
          to the issuer and the depth of the market for that security.  Other
          market risks that can affect value include a market's current
          attitudes about type of security, market reactions to political or
          economic events, and tax and regulatory effects (including lack of
          adequate regulations for a market or particular type of instrument).
          Market restrictions on trading volume can also affect price and
          liquidity.
    
          Prices of most securities tend to be more volatile in the short-term.
          Therefore, an investor who trades frequently or redeems in the short-
          term is more likely to incur loss than an investor who holds
          investments for the long term.  The fewer the number of issuers in
          which the Fund invests, the greater the potential volatility of its
          portfolio.  A security that is leveraged, whether explicitly or
          implicitly, will also tend to be more volatile in that both gains and
          losses are intensified by the magnifying effects of leverage.  Certain
          instruments (such as inverse floaters and interest-only securities)
          behave similarly to leveraged instruments.     
    
          The Adviser may temporarily invest up to 100% of the Fund's assets in
          high quality, short-term money market instruments if it believes
          adverse economic or market conditions, such as excessive volatility or
          sharp market declines, justify taking a defensive investment posture.
          If the Fund attempts to limit investment risk by temporarily taking a
          defensive investment position, it may be unable to pursue its
          investment objective during that time, and it may miss out on some or
          all of an upswing in the securities markets.

- -----------------------------

Fixed Income Securities
- -----------------------
    
          Fixed income securities are subject to various risks.  The two primary
          (but not exclusive) risks affecting fixed income instruments are
          "credit risk" and "interest rate risk."  These risks can affect a
          security's price volatility to varying degrees, depending upon the
          nature of the instrument.  In addition, the depth and liquidity of the
          market for an individual or class of fixed income security can also
          affect its price and, hence, the market value of the Fund.     

          "Credit risk" refers to the likelihood that an issuer will default in
          the payment of principal and/or interest on an instrument.  Financial
          strength and solvency of an issuer are the primary factors influencing
          credit risk.  In addition, lack of or inadequacy of collateral or
          credit enhancements for a fixed income security may affect its credit
          risk.  Credit risk of a security may change over its life and
          securities which are rated by rating agencies are often reviewed and
          may be subject to downgrades.

          The Fund may invest in debt instruments rated below investment grade.
          Debt securities that are rated below investment grade are considered
          to be speculative; they are also commonly known as "junk" bonds.
          Generally, lower-rated debt securities provide a higher yield than
          higher rated debt securities of similar maturity but are subject to
          greater credit risk than higher rated securities of similar maturity.
          These securities are regarded as predominantly speculative with
          respect to the issuer's continuing ability to meet principal and
          interest payments.  Because investment in lower quality securities
          involves greater investment risk, achievement of the Fund's investment
          objective will be more dependent 

                                       12
<PAGE>
 
          on the Adviser's analysis than would be the case if the Fund were
          investing in higher quality bonds. In addition, lower quality
          securities may be more susceptible to real or perceived adverse
          economic and individual corporate developments than would investment
          grade bonds. Moreover, the secondary trading market for lower quality
          securities may be less liquid than the market for investment grade
          bonds. This potential lack of liquidity may make it more difficult for
          the Adviser to value accurately certain portfolio securities.

          "Interest rate risk" refers to the change in value of debt instruments
          associated with changes in interest rates.  Interest rate changes may
          affect the value of a fixed income security directly (especially in
          the case of fixed rate securities) and indirectly (especially in the
          case of adjustable rate securities).  In general, rises in interest
          rates will negatively impact the value of fixed rate securities and
          falling interest rates will have a positive effect on value.  The
          degree to which a security's price will change as a result of changes
          in interest rates is measured by its "duration."  For example, the
          price of a bond with a 5-year duration would be expected under normal
          market conditions to decrease 5% for every 1% increase in interest
          rates.  Generally, securities with longer maturities have a greater
          duration and thus are subject to greater price volatility from changes
          in interest rates.  Adjustable rate instruments also react to interest
          rate changes in a similar manner although generally to a lesser degree
          (depending, however, on the characteristics of the reset terms,
          including the index chosen, frequency of reset and reset caps or
          floors, among other things).

Foreign Investing
- ----------------------

          Investment in foreign securities involves special risks in addition to
          the usual risks inherent in domestic investments.  These include:
          political or economic instability; the unpredictability of
          international trade patterns; the possibility of foreign governmental
          actions such as expropriation, nationalization or confiscatory
          taxation; the imposition or modification of currency exchange or
          foreign investment controls; the imposition of withholding taxes on
          dividends, interest and gains; price volatility; and fluctuations in
          currency exchange rates.   These risks are more pronounced in emerging
          market countries.

          As compared to United States companies, foreign issuers generally
          disclose less financial and other information publicly and are subject
          to less stringent and less uniform accounting, auditing and financial
          reporting standards.  Foreign countries typically impose less thorough
          regulations on brokers, dealers, stock exchanges, insiders and listed
          companies than does the United States, and foreign securities markets
          may be less liquid and more volatile than domestic markets.
          Investment in foreign securities involves higher costs than investment
          in U.S. securities, including higher transaction and custody costs as
          well as the imposition of additional taxes by foreign governments.  In
          addition, security trading practices abroad may offer less protection
          to investors such as the Fund.  Settlement of transactions in some
          foreign markets may be delayed or may be less frequent than in the
          U.S., which could affect the liquidity of the Fund's portfolio.  Also,
          it may be more difficult to obtain and enforce legal judgments against
          foreign corporate issuers than against

                                       14
<PAGE>
 
          domestic issuers and it may be impossible to obtain and enforce
          judgments against foreign governmental issues.
    
          Because foreign securities generally are denominated and pay dividends
          or interest in foreign currencies, and the Fund may hold various
          foreign currencies from time to time, the value of the net assets of
          the Fund as measured in United States dollars can be affected
          favorably or unfavorably by changes in exchange rates. Generally,
          currency exchange transactions will be conducted on a spot (i.e.,
                                                                      ----
          cash) basis at the spot rate prevailing in the currency exchange
          market. The cost of currency exchange transactions will generally be
          the difference between the bid and offer spot rate of the currency
          being purchased or sold. In order to protect against uncertainty in
          the level of future foreign currency exchange rates, the Fund is
          authorized to enter into certain foreign currency futures and forward
          contracts. However, it is not obligated to do so and, depending on the
          availability and cost of these devices, the Fund may be unable to use
          foreign currency futures and forward contracts to protect against
          currency uncertainty. Please see the Statement of Additional
          Information for further information.     

          With respect to the Fund, the forward currency market for the purchase
          or sale of U.S. dollars in some countries is not highly developed, and
          in certain countries, there may be no such market.  If a devaluation
          of a currency is generally anticipated, the Fund may not be able to
          contract to sell the currency at an exchange rate more advantageous
          than that which would prevail after the anticipated amount of
          devaluation, particularly as regards forward contracts for local
          currencies in view of the relatively small, inactive or even non-
          existent market for these contracts.  In the event the Fund holds
          securities denominated in a currency that suffers a devaluation, the
          Fund's net asset value will suffer corresponding reductions.  In this
          regard, in December 1994, the Mexican government determined to allow
          the Mexican peso to trade freely against the U.S. dollar rather than
          within a controlled band, which resulted in a significant devaluation
          of the Mexican peso against the dollar.  Further, in July 1997, the
          Thai and Philippine governments allowed the baht and peso,
          respectively, to trade freely against the U.S. dollar resulting in a
          sharp devaluation of both currencies, and in 1998 Russia did the same,
          causing a sharp devaluation of the ruble.

Mortgage-Backed Securities
- ----------------------------
    
          Credit and Market Risks of Mortgage-Backed Securities.  The
          investments by the Fund in fixed rate and floating rate mortgage-
          backed securities will entail normal credit risks (i.e., the risk of
                                                             ----             
          non-payment of interest and principal) and market risks (i.e., the
                                                                   ----     
          risk that interest rates and other factors will cause the value of the
          instrument to decline).  Many issuers or servicers of mortgage-backed
          securities guarantee timely payment of interest and principal on the
          securities, whether or not payments are made when due on the
          underlying mortgages.  This kind of guarantee generally increases the
          quality of a security, but does not mean that the security's market
          value and yield will not change.  Like bond investments, the value of
          fixed rate mortgage-backed securities will tend to rise when interest
          rates fall, and fall when rates rise.  Floating rate mortgage-backed
          securities will generally tend to have minimal changes in price when
          interest rates rise or fall, but their current yield will be affected.
          The value of all mortgage-backed securities may also change because of
          changes in the market's perception of the creditworthiness of the
          organization that issued or guarantees them.  In addition, the
          mortgage-backed securities market in general may be adversely affected
          by changes in governmental legislation or regulation.  Fluctuations in
          the market value of mortgage-backed securities after their acquisition
          usually do not affect cash income from these securities but are
          reflected in the Fund's net asset value. Factors that could affect the
          value of a mortgage-backed security include, among other things, the
          types and amounts of insurance which a mortgagor carries, the amount
          of time the mortgage loan has been outstanding, the loan-to-value
          ratio of     

                                       16
<PAGE>
 
          each mortgage and the amount of overcollateralization of a mortgage
          pool.

          Liquidity Risk of Mortgage-Backed Securities.  The liquidity of
          mortgage-backed securities varies by type of security; at certain
          times the Fund may encounter difficulty in disposing of investments.
          Because mortgage-backed securities may be less liquid than other
          securities, the Fund may be more susceptible to liquidity risks than
          funds that invest in other securities.  In the past, in stressed
          markets, certain types of mortgage-backed securities, such as inverse
          floaters, and interest-only securities, suffered periods of
          illiquidity if disfavored by the market.

          Prepayment, Extension and Redemption Risks of Mortgage-Backed
          Securities.  Mortgage-backed securities reflect an interest in monthly
          payments made by the borrowers who receive the underlying mortgage
          loans.  Although the underlying mortgage loans are for specified
          periods of time, such as 20 or 30 years, the borrowers can, and
          typically do, pay them off sooner.  When that happens, the mortgage-
          backed security which represents an interest in the underlying
          mortgage loan will be prepaid.  A borrower is more likely to prepay a
          mortgage which bears a relatively high rate of interest.  This means
          that in times of declining interest rates, a portion of the Fund's
          higher yielding securities are likely to be redeemed and the Fund will
          probably be unable to replace them with securities having as great a
          yield.  Prepayments can result in lower yields to shareholders.  The
          increased likelihood of prepayment when interest rates decline also
          limits market price appreciation of mortgage-backed securities.  This
          is known as prepayment risk.  Mortgage-backed securities are also
          subject to extension risk.  Extension risk is the possibility that
          rising interest rates may cause prepayments to occur at a slower than
          expected rate.  This particular risk may effectively change a security
          which was considered short or intermediate term into a long term
          security.  Long-term return securities generally fluctuate more widely
          in response to changes in interest rates than short or intermediate-
          term securities.  In addition, a mortgage-backed security may be
          subject to redemption at the option of the issuer.  If a mortgage-
          backed security held by the Fund is called for redemption, the Fund
          will be required to permit the issuer to redeem or "pay-off" the
          security, which could have an adverse effect on the Fund's ability to
          achieve its investment objective.

          Collateralized Mortgage Obligations.  There are certain risks
          associated specifically with collateralized mortgage obligations
          ("CMOs.")  CMOs are debt obligations collateralized by mortgage loans
          or mortgage pass-through securities.  The average life of CMOs is
          determined using mathematical models that incorporate prepayment
          assumptions and other factors that involve estimates of future
          economic and market conditions.  These estimates may vary from actual
          future results, particularly during periods of extreme market
          volatility.  Further, under certain market conditions, such as those
          that occurred in 1994, the average weighted life of certain CMOs may
          not accurately reflect the price volatility of such securities.  For
          example, in periods of supply and demand imbalances in the market for
          such securities and/or in periods of sharp interest rate movements,
          the prices of CMOs may fluctuate to a greater extent than would be
          expected from interest rate movements alone. CMOs issued by private
          entities are not obligations issued or guaranteed by the United States
          Government, its agencies or instrumentalities and are not guaranteed
          by any government agency, although the securities underlying a CMO may
          be subject to a guarantee.  Therefore, if the collateral securing the
          CMO, as well as any third party credit support or guarantees, is
          insufficient to make payment, the holder could sustain a loss.
    
          Stripped Mortgage Securities.  Part of the investment strategy of the
          Fund involves interest-only Stripped Mortgage Securities.  These
          investments may be highly sensitive to changes in interest 
          and tend to be less liquid than other CMOs. In addition, prepayments
          of the underlying mortgages likely would lower the Fund's return from
          stripped securities it holds.      

          Adjustable Rate Mortgages.  ARMs contain maximum and minimum rates
          beyond which the mortgage interest rate may not vary over the lifetime
          of the security.  In addition, many ARMs provide for additional
          limitations on the maximum amount by which the mortgage interest rate
          may adjust for any single adjustment period.  Alternatively, certain
          ARMs contain limitations on changes in the required monthly payment.
          In the event that a monthly payment is not sufficient to pay the
          interest accruing on an ARM, any excess interest is added to the
          principal balance of the mortgage loan, which is repaid through future
          monthly payments.  If the monthly payment for such an instrument
          exceeds the sum of the interest accrued at the applicable mortgage
          interest rate and the principal payment required at such point to
          amortize the outstanding 

                                       18
<PAGE>
 
          principal balance over the remaining term of the loan, the excess is
          utilized to reduce the then-outstanding principal balance of the ARM.

          Asset-Backed Securities.  Certain asset-backed securities do not have
          the benefit of the same security interest in the related collateral as
          do mortgage-backed securities; nor are they provided government
          guarantees of repayment.  Credit card receivables are generally
          unsecured, and the debtors are entitled to the protection of a number
          of state and federal consumer credit laws, many of which give such
          debtors the right to set off certain amounts owed on the credit cards,
          thereby reducing the balance due.  In addition, some issuers of
          automobile receivables permit the servicers to retain possession of
          the underlying obligations.  If the servicer were to sell these
          obligations to another party, there is a risk that the purchaser would
          acquire an interest superior to that of the holders of the related
          automobile receivables.

Year 2000
- ---------------
    
          The investment advisory and management services provided by the
          Adviser and the services provided to shareholders by the Transfer
          Agent depend on the smooth functioning of their computer systems.
          Many computer software systems in use today cannot recognize the year
          2000, but revert to 1900 or some other date, due to the manner in
          which dates were encoded and calculated.  Such a failure could have a
          negative impact on the handling of securities trades, pricing and
          account services.  The Adviser and the Transfer Agent have been
          actively working on necessary changes to their own computer systems to
          prepare for the year 2000 and expect that their systems will be
          adapted for year 2000 compliance before that date, but there can be no
          assurance that they will be successful, or that interaction with other
          non-complying computer systems will not impair their services at that
          time.  The Adviser has been, and is currently in contact with each of
          its External Service Providers to evaluate their readiness for the
          year 2000.  The Adviser has requested each of its External Service
          Providers to either; (i) prepare a description of its process for
          identifying date sensitive areas, its approach for implementing
          changes, its testing methodology, along with its timetable for
          completion, or (ii) certify its year 2000 compliance.     


          In addition, it is possible that the markets for securities in which
          the Fund invests may be negatively affected by computer failures
          throughout the financial services industry commencing January 1, 2000.
          Improperly functioning trading systems may result in settlement
          problems.  In addition, corporate and governmental data processing
          errors may result in production problems for individual companies and
          create overall economic uncertainties.  Earnings of individual issuers

                                       20
<PAGE>
 
          will be affected by remediation costs which may be substantial.
          Individual firms may further experience disruptions to their business
          due to the failure of their counterparts to address approaching year
          2000 problems, or could experience further disruption to the economy
          at large, which could adversely affect corporate earnings generally
          and the value of their securities.  Accordingly, the Fund's portfolio
          investments may be negatively affected.

European Economic and Monetary Union
- ------------------------------------
    
          The Fund may invest in European countries that have agreed to enter
          into the European Monetary Union (EMU).  EMU is an effort by certain
          European countries to, among other things, reduce barriers between
          countries and eliminate fluctuations in their currencies.  Among other
          things, EMU establishes a single European currency (the euro), which
          was introduced on January 1, 1999 and is expected to replace the
          existing national currencies of all initial EMU participants by July
          1, 2002. Upon introduction of the euro, certain securities (beginning
          with government and corporate bonds) have been redonominated in the
          euro and, thereafter trade and make dividend and other payments only
          in euros.     
    
          Like other investment companies and business organizations, including
          the companies in which the Fund invests, the Fund could be adversely
          affected: (i) if the euro, or EMU as a whole does not take effect; 
          (ii) if a participating country withdraws from EMU; or (iii) if the
          computing, accounting and trading systems used by the Fund's service
          providers, or by other business entities with which the Fund or its
          service providers do business, are not capable of recognizing the euro
          as a distinct currency at the time of, and following euro
          conversion.

          Advisory Agreement
    
          The Company and the Adviser have entered into an Investment Advisory
          and Management Agreement (the "Advisory Agreement"), under the terms
          of which the Company has employed the Adviser to manage the investment
          of its assets, to place orders for the purchase and sale of its
          portfolio securities, and to be responsible for overall management of
          the Company's business affairs, subject to control by the Board of
          Directors of the Company.  The Adviser also pays certain costs of
          marketing the Fund, including sales personnel compensation, from its
          legitimate profits from its investment advisory fees and other
          resources available to it. Under the Advisory Agreement, the Fund pays
          to the Adviser as compensation for the services rendered, facilities
          furnished, and expenses paid by it the following fees:

          for any error of judgment or mistake of law or for any loss suffered
          by the Fund in connection with the matters to which the agreements
          relate, except a loss resulting from willful misfeasance, bad faith,
          gross negligence on the part of the Adviser in the performance of its
          duties or from reckless disregard by the Adviser of its duties under
          the agreement.

LOGO      MULTIPLE CLASS STRUCTURE
- ----------------------------------
    
          The Fund currently offers two classes of shares, Institutional Class
          shares and Class N shares.  Shares of each class of the Fund
          represents an equal pro rata interest in that Fund and generally give
          you the same voting, dividend, liquidation, and other rights.  The
          Institutional Class shares are offered at the current net asset value.
          The Class N shares are also offered at the current net asset value,
          but will be subject to fees imposed under a distribution plan
          ("Distribution Plan") adopted pursuant to Rule 12b-1 under the
          Investment Company Act of 1940, as amended, by the Fund.  The
          Distribution Plan allows the Fund to pay distribution and other fees
          for the sale of its Class N shares and for services provided to
          shareholders. Pursuant to the Distribution Plan, the Fund compensates
          the Fund's distributor at a rate equal to 0.25% of the average daily
          net assets of the Fund attributable to its Class N shares. Because
          these fees are paid out of the Fund's Class N assets on an on-going
          basis, over time, these fees will increase the cost of your investment
          and may cost you more than paying other types of sales charges.

- ----------------------------------------

          Buying shares
    
          You pay no sales charges to invest in the Fund.  Your price for Fund
          shares is the Fund's net asset value per share (NAV) which is
          calculated as of the close of trading on the New York Stock Exchange
          (usually 4:00 p.m. Eastern time) every day the exchange is open. Your
          order will be priced at the next NAV calculated after your order is
          accepted by the Fund. Orders received by the Fund's Transfer agent
          from dealers, brokers or other service providers after the NAV for the
          day is determined, will receive that same day's NAV if the orders were
          received by the dealers, brokers or service providers from their
          customers prior to 4:00 p.m. and were transmitted to and received by
          the transfer agent prior to 8:00 a.m. Eastern time on the next day.
          The Fund's investments are valued based on market value, or where
          market quotations are not readily available, based on fair value as
          determined in good faith by the Fund pursuant to procedures
          established by the Fund's Board.

          Selling shares

          You may sell shares at any time.  Your shares will be sold at the next
          NAV calculated after your order is accepted by the Fund's transfer
          agent.  Any certificates representing Fund shares being sold must be
          returned with your redemption request.  Your order will be processed
          promptly and you will generally receive the proceeds within a week.

          Before selling recently purchased shares, please note that if the Fund
          has not yet collected payment for the shares you are selling, it may
          delay sending the proceeds for up to fifteen days.

          Written sell order

          Some circumstances require written sell orders, along with signature
          guarantees.  These include:
    
          .  amounts of $100,000 or more     

          .  amounts of $1,000 or more on accounts whose address has been
             changed within the last 30 days

          .  requests to send the proceeds to a payee or address different than
             what is on our records

          A signature guarantee helps protect against fraud.  You can obtain one
          from most banks or securities dealers but not from a notary public.
          Please call us to ensure that your signature guarantee will be
          processed correctly.

          Exchange privilege

          You can exchange from one Class N Galileo Fund into another.  You can
          request your exchange in writing or by phone.  Be sure to read the
          current prospectus for any Fund into which you are exchanging.  Any
          new account established through an exchange will have the same
          privileges as your original account (as long as they are available).

          Third Party Transactions

          You may buy and redeem Fund shares through certain broker-dealers and
          financial organizations and their authorized intermediaries.  If
          purchases and redemptions of Fund shares are arranged and settlement
          is made at an investor's election through a registered broker-dealer,
          other than the 

                                       27

          Fund's distributor, that broker-dealer may at its discretion, charge a
          fee for that service.

          Account statements

          Every investor automatically receives regular account statements.  You
          will also be sent a yearly statement detailing the tax characteristics
          of any dividends and distributions you have received.

LARGE REDEMPTION AMOUNTS
- ------------------------

The Fund also reserves the right to make a "redemption in kind" -- payment in 
portfolio securities rather than cash -- if the amount you are redeeming in any 
90-day period is large enough to affect Fund operations (for example, if it  
equals more than $250,000 or represents more than 1% of the Fund's assets).

          General policies

          If your account falls below $1,000 as a result of redemptions and or
          exchanges for six months or more, the Fund may close your account and
          send you the proceeds upon 60 days' written notice

          Unless you decline telephone privileges on your New Account Form, you
          may be responsible for any fraudulent telephone order as long as the
          Transfer Agent takes reasonable measures to verify the order.
    
          The Fund restricts excessive trading (usually defined as more than
          four exchanges out of the Fund within a calendar year).  You are
          limited to one exchange of shares in the Fund during any 15-day period
          except investors in 401(k) and other group retirement accounts, 
          investors who purchase shares through certain broker-dealers, and
          asset allocation accounts managed by the Adviser or an affiliate. The
          Fund reserves the right to:     

          .  refuse any purchase or exchange request that could adversely affect
             the Fund or its operations, including those from any individuals or
             groups who, in the Fund's view, are likely to engage in excessive
             trading
    
          .  change or discontinue its exchange privilege, or temporarily
             suspend this privilege during unusual market conditions.     
    
          .  delay sending out redemption proceeds for up to seven days
             (generally applies only in cases of very large redemptions,
             excessive trading or during unusual market conditions)

LOGO      DISTRIBUTIONS AND TAXES
- ---------------------------------

          The amount of dividends of net investment income and distributions of
          net realized long and short-term capital gains payable to shareholders
          will be determined separately for the Fund.  Dividends from the net
          investment income of the Fund will be declared and paid monthly.  The
          Fund will distribute any net realized long or short-term capital gains
          at least annually.  Your distributions will be reinvested in the Fund
          unless you instruct the Fund otherwise.  There are no fees or sales
          charges on reinvestments.

          In any fiscal year in which the Fund qualifies as a regulated
          investment company and distributes to shareholders all of its net
          investment income and net capital gains, the Fund is relieved of
          federal income tax.

          Generally, all dividends and capital gains are taxable whether they
          are reinvested or received in cash- unless you are exempt from
          taxation or entitled to tax deferral.  Capital gains distributions may
          be taxable at different rates depending on the length of time the Fund
          has held the assets sold.  Early each year, you will be notified as to
          the amount and federal tax status of all distributions paid during the
          prior year.  Distributions may also be subject to state or local
          taxes.  The tax treatment of redemptions from a retirement plan
          account may differ from redemptions from an ordinary shareholder
          account.  If you redeem shares of the Fund or exchange them for shares
          of another Fund, any gain on the transaction may be subject to tax.
          You must provide the Funds with a correct taxpayer identification
          number (generally your Social Security Number) and certify that you
          are not subject to backup withholding.  If you fail to do so, the IRS
          can require the Fund to withhold 31% of your taxable distributions and
          redemptions.  Federal law also requires the Fund to withhold 30% or
          the applicable tax treaty rate from dividends paid to nonresident
          alien, non-U.S. partnership and non-U.S. corporation shareholder
          accounts.

          This is a brief summary of some of the tax laws that affect your
          investment in the Fund.  Please see the Statement of Additional
          Information and your tax adviser for further information.

LOGO      FINANCIAL HIGHLIGHTS
- ------------------------------

          The financial highlights table is intended to help you understand the
          Fund's financial performance for the fiscal years indicated.  Certain
          information reflects financial results for a single Fund share.
          "Total return" shows how much your investment in the Institutional
          Class shares of the Fund would have increased (or decreased) during
          each period, assuming you had reinvested all dividends and
          distributions (Class N shares of the Fund commenced operations on
          March 1, 1999).  These figures have been audited by Deloitte & Touche
          LLP, whose report, along with Company's financial statements, are
          included in the annual report, which is available upon request.

INVESTMENT OBJECTIVES AND PRINCIPAL STRATEGIES

The Fund is affected by changes in the economy, or in securities and other
markets.  There is also the possibility that investment decisions the Adviser
makes will not accomplish what they were designed to achieve, or that companies
in which the Fund invests will have disappointing performance or not pay their
debts.

Under adverse market conditions, the Fund could invest some or all of its assets
in money market securities. Although the Fund would do this only in seeking to
avoid losses, it could have the effect of reducing the benefit from any upswing
in the market.

PRINCIPAL RISKS

Risk is the chance that you will lose money on your investment or that it will
not earn as much as you expect. In general, the greater the risk, the more money
your investment can earn for you and the more you can lose. Since shares of the
Fund represent an investment in securities with fluctuating market prices, the
value of Fund shares will vary as the value of the Fund's portfolio securities
increases or decreases. Therefore, the value of an investment in the Fund could
go down as well as up. All investments are subject to:
    
 .    MARKET RISK      

     There is the possibility that the returns from the types of securities in
     which the Fund invests will underperform returns from the various general
     securities markets. Different types of securities tend to go through cycles
     of outperformance and underperformance in comparison to the general
     securities markets.

 .    SECURITIES SELECTION RISK

     There is the possibility that the specific securities held in the Fund's
     portfolio will underperform the other funds in the same asset class, or
     benchmarks that are representative of the general performance of the asset
     class, because of the portfolio manager's choice of securities.

 .    FOREIGN INVESTING RISK
    
     There is the likelihood that foreign investments may be riskier than U.S.
     investments because of a lack of political stability, foreign controls on
     investment and currency exchange rates, fluctuations in currency exchange
     rates, withholding taxes, and lack of adequate company information. The
     Fund is subject to foreign investing risk because it invests primarily in
     the assets of foreign companies. Because the Fund invests in securities of
     emerging market countries, the risk factors listed above are more likely to
     occur. In addition, because foreign securities generally are denominated
     and pay dividends or interest in foreign currencies, and the Fund holds
     various foreign currencies, the value of the net assets of the Fund as
     measured in United States dollars will be affected favorably or unfavorably
     by changes in exchange rates.     

The Fund may also be subject (in varying degrees) to the following risks:

 .    LIQUIDITY RISK

     There is the possibility that the Fund may lose money or be prevented from
     earning capital gains if it cannot sell a security at the time and price
     that is most beneficial to the Fund.  The Fund is subject to liquidity risk
     because foreign securities may be less liquid than U.S. securities.

 .    PRICE VOLATILITY

     There is the possibility that the value of the Fund's portfolio will change
     as the prices of its investments go up or down.  Although stocks offer the
     potential for greater long-term growth than most fixed income securities,
     stocks generally have higher short-term volatility.  The Fund is subject to
     this risk.

Because the Fund is non-diversified for 1940 Act purposes, it may invest more
than 5% of its total assets in the securities of any one issuer.  Consequently,
its exposure to credit and market risks associated with that issuer is
increased.

Your investment is not a bank deposit, and it is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE SUMMARY
     
The two tables below show the Fund's annual returns and its long-term
performance with respect to its Institutional Class shares (Class N shares of
the Fund commenced operations on March 1, 1999). The first table shows you how
the Fund's performance has varied from year to year. The second compares the
Fund's performance over time to that of a broad-based securities index. Both
tables assume reinvestment of dividends and distributions. The performance
information includes performance of the predecessor limited partnership, which
was managed by a predecessor of TCW Funds Management, Inc. using the same
investment strategy as the Fund. The performance of the partnership was
calculated using performance standards applicable to private investment
partnerships which take into account all elements of total return and reflect
the deduction of all fees and expenses of operation. The predecessor limited
partnership, was not registered under the Investment Company Act of 1940 ("1940
Act") and therefore, was not subject to certain investment restrictions imposed
by the 1940 Act and Subchapter M of the Internal Revenue Code of 1986, as
amended. If the limited partnership had been registered under the 1940 Act its
performance could have been adversely affected. As with all mutual funds, past
performance is not a prediction of future results.

FUND EXPENSES AND EXPENSE EXAMPLE

As an investor, you pay certain fees and expenses in connection with the Fund,
which are described in the table below.  Annual fund operating expenses are paid
out of Fund assets, so their effect is included in the share price.  The Class N
shares of the Fund have no sales charge (load), but are subject to Rule 12b-1
distribution fees.

EXPENSE EXAMPLE

This Example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other mutual funds.
    
This Example shows what you could pay in expenses over time. It uses the same
hypothetical conditions other funds use in their prospectuses: $10,000 Initial
Investment, 5% total return each year and no changes in expenses. The figures
shown would be the same whether or not you sold your shares at the end of a
period. Because actual return and expenses will be higher or lower, the Example
is for comparison purposes only.

          TCW Galileo European Equities Fund


INVESTMENT OBJECTIVES/APPROACH
    
          The Fund seeks long-term capital appreciation. To pursue this goal, it
          invests primarily in the securities of issuers located in Europe. The
          Fund invests (except when maintaining temporary defensive position) at
          least 65% of the value of its total assets in equity securities issued
          by European Companies. These securities include common and preferred
          stocks, rights or warrants to purchase common stock and convertible
          debt or equity securities. The Fund invests in companies based in at
          least three European countries.      

          In managing the Fund's investments, the Adviser seeks to emphasize
          companies which are moving towards the North American concept of
          shareholder value.

          The Adviser also seeks investment opportunities resulting from the
          fact that economic ties between the former "Eastern bloc" countries of
          Europe and other European countries have been strengthened. The Fund
          will not invest more than 30% of its total assets in issuers based in
          former "Eastern bloc" countries, or more than 10% of its total assets
          in issuers based in any one former "Eastern bloc" country.

          JAMES M. BURNS AND SAKER A. NUSSEIBEH ARE THE FUND'S PORTFOLIO
          MANAGERS.

Concepts to understand

EUROPEAN COMPANY (i) is organized under the laws of a European country and has a
principal office in Europe; or (ii)  derives 50% or more of its gross revenues
or profits from goods produced or sold, investments made, or services performed
in European countries or has at least 50% of its assets situated in Europe; or
(iii) its equity securities are traded principally on a stock exchange or over-
the-counter in a European country.

                                       8
<PAGE>
 
          MAIN RISKS

          The Fund holds primarily stocks, which may go up or down in value,
          sometimes rapidly and unpredictably. Although stocks offer the
          potential for greater long-term growth than most fixed income
          securities, stocks generally have higher short-term volatility. In
          addition, the Fund may hold convertible debt securities. Many
          convertible debt securities are rated below investment grade and are
          considered speculative by rating agencies as to repayment of principal
          and interest.

          The primary risks affecting this Fund are "foreign investing risk,"
          "liquidity risk," and "price volatility." The Fund is subject to
          foreign investing risk because it invests in securities issued by
          foreign governments or companies. FOREIGN INVESTING RISK refers to the
          likelihood that foreign investments may be riskier than U.S.
          investments because of many factors, some of which include:

          .  a lack of political or economic stability

          .  foreign controls on investment and currency exchange rates

          .  withholding taxes

          .  a lack of adequate company information
    
          Because the Fund invests in the securities of emerging market
          countries, these risk factors are more pronounced. In addition,
          securities traded only through foreign markets may be more volatile
          and are often harder to sell. The Fund also is subject to foreign
          currency risk. Because foreign securities generally are denominated
          and pay dividends or interest in foreign currencies, the value of the
          net assets of the Fund as measured in U.S. dollars will be affected
          favorably or unfavorably by changes in exchange rates. LIQUIDITY RISK
          refers to the possibility that the Fund may lose money or be prevented
          from earning capital gains if it cannot sell a security at the time
          and price that is most beneficial to the Fund. Because foreign
          securities may be less liquid than U.S. securities, the Fund may be
          more susceptible to liquidity risk than funds that invest in U.S.
          securities. PRICE VOLATILITY refers to the possibility that the value
          of the Fund's portfolio will change as the prices of its investments
          go up or down. This Fund may be subject to greater price volatility
          than funds that invest in the securities of U.S. companies.      

          The Fund may invest some assets in options, futures and foreign
          currency futures and forward contracts. These practices are used

                                       9
<PAGE>
 
          primarily to hedge the Fund's portfolio but may be used to increase
          returns; however, such practices sometimes may reduce returns or
          increase volatility.

          The Fund seeks to earn additional income by making loans of its
          portfolio securities to brokers, dealers and other financial
          institutions. The loans will be secured at all times by cash and
          liquid high grade debt obligations. As with any extension of credit,
          there are risks of delay in recovery and in some cases even loss of
          rights in the collateral should the borrower fail financially.
    
          The fund may engage in active portfolio management which may result in
          increased fund transaction expenses and have tax consequences such as
          increased realized gains for investors.      

                                       10

RISK CONSIDERATIONS

          Please consider the following risks before investing in the Fund.

          Various market risks can affect the price or liquidity of an issuer's
          securities. Adverse events occurring with respect to an issuer's
          performance or financial position can depress the value of the
          issuer's securities. The liquidity in a market for a particular
          security will affect its value and may be affected by factors relating
          to the issuer, as well as the depth of the market for that security.
          Other market risks that can affect value include a market's current
          attitudes about type of security, market reactions to political or
          economic events, and tax and regulatory effects (including the lack of
          adequate regulations for a market or particular type of instrument).
          Market restrictions on trading volume can also affect price and
          liquidity.

          Prices of most securities tend to be more volatile in the short-term.
          Therefore, an investor who trades frequently or redeems in the short-
          term is more likely to incur loss than an investor who holds
          investments for the long term. The fewer the number of issuers in
          which a Fund invests, the greater the potential volatility of its
          portfolio.
    
          The Adviser may temporarily invest up to 100% of the Fund's assets in
          high quality, short-term money market instruments if it believes
          adverse economic or market conditions, such as excessive volatility or
          sharp market declines, justify taking a defensive investment posture.
          If the Fund attempts to limit investment risk by temporarily taking a
          defensive investment position, it may be unable to pursue its
          investment objective during that time, and it may miss out on some or
          all of an upswing in the securities markets.     

GENERAL INVESTMENT RISK

Since shares of the Fund represent an investment in securities with fluctuating
market prices, the value of Fund shares will vary as the value of the Fund's
portfolio securities increases or decreases. Therefore, the value of an
investment in the Fund could go down as well as up.

                                      11
<PAGE>
 
          

RISK CONSIDERATIONS

          FOREIGN INVESTING

          Investment in foreign securities involves special risks in addition to
          the usual risks inherent in domestic investments. These include:
          political or economic instability; the unpredictability of
          international trade patterns; the possibility of foreign governmental
          actions such as expropriation, nationalization or confiscatory
          taxation; the imposition or modification of foreign currency or
          foreign investment controls; the imposition of withholding taxes on
          dividends, interest and gains; price volatility; and fluctuations in
          currency exchange rates.

          As compared to United States companies, foreign issuers generally
          disclose less financial and other information publicly and are subject
          to less stringent and less uniform accounting, auditing and financial
          reporting standards. Foreign countries typically impose less thorough
          regulations on brokers, dealers, stock exchanges, insiders and listed
          companies than does the United States. Foreign securities markets may
          be less liquid and more volatile than domestic markets. Investment in
          foreign securities involves higher costs than investment in United
          States securities, including higher transaction and custody costs as
          well as the imposition of additional taxes by foreign governments. In
          addition, security trading practices abroad may offer less protection
          to investors such as the Fund. Settlement of transactions in some
          foreign markets may be delayed or may be less frequent than in the
          United States, which could affect the liquidity of the Fund's
          portfolio. Also, it may be more difficult to obtain and enforce legal
          judgments against foreign corporate issuers

                                       12
<PAGE>
 
          than against domestic issuers and it may be impossible to obtain and
          enforce judgments against foreign governmental issuers.
    
          Because foreign securities generally are denominated and pay dividends
          or interest in foreign currencies, and the Fund holds various foreign
          currencies from time to time, the value of the net assets of the Fund
          as measured in U.S. dollars will be affected favorably or unfavorably
          by changes in exchange rates. Generally, currency exchange
          transactions will be conducted on a spot (i.e., cash) basis at the
          spot rate prevailing in the currency exchange market. The cost of
          currency exchange transactions will generally be the difference
          between the bid and offer spot rate of the currency being purchased or
          sold. In order to protect against uncertainty in the level of further
          foreign currency exchange rates, the Fund is authorized to enter into
          certain foreign currency futures and forward contracts. However, it is
          not obligated to do so and, depending on the availability and cost of
          these services, the Fund may be unable to use foreign currency futures
          and forward contracts to protect against currency uncertainty. Please
          see the Statement of Additional Information for further information. 
     
    
          The forward currency market for the purchase or sale of U.S. dollars
          in most countries is not highly developed, and in certain countries,
          there may be no such market. If a devaluation of a currency is
          generally anticipated, the Fund may not be able to contract to sell
          the currency at an exchange rate more advantageous than that which
          would prevail after the anticipated amount of the devaluation. In the
          event the Fund holds securities denominated in a currency that suffers
          a devaluation, the Fund's net asset values will suffer corresponding
          reductions. In this regard, in December 1994, the Mexican government
          determined to allow the Mexican peso to trade freely against the U.S.
          dollar, rather than within a controlled band, which action resulted in
          a significant devaluation of the Mexican peso against the dollar.
          Further, in July 1997, the Thai and Philippine governments allowed the
          baht and peso, respectively, to trade freely against the U.S. dollar
          resulting in a sharp devaluation of both currencies, and in 1998
          Russia did the same, causing a sharp devaluation of the ruble.

RISK CONSIDERATIONS

          RISKS ASSOCIATED WITH EMERGING MARKET COUNTRIES

          Investors should recognize that investing in securities of emerging
          market countries involves certain risks, and considerations, including
          those set forth below, which are not typically associated with
          investing in the United States or other developed countries.

          Political and economic structures in many emerging markets countries
          may be undergoing significant evolution and rapid development, and
          such countries may lack the social, political and economic stability
          characteristics of more developed countries. Some of these countries
          may have in the past failed to recognize private property rights and
          have at times nationalized or expropriated the assets of private
          companies.

          The securities markets of emerging market countries are substantially
          smaller, less developed, less liquid and more volatile than the major
          securities markets in the United States and other developed nations.
          The limited size of many emerging securities markets and limited
          trading volume in issuers compared to the volume of trading in U.S.
          securities or securities of issuers in other developed countries could
          cause prices to be erratic for reasons apart from factors that affect
          the quality of the securities. For example, limited market size may
          cause prices to be unduly influenced by traders who control large
          positions. Adverse publicity and investors' perceptions, whether or
          not based on fundamental analysis, may decrease the value and
          liquidity of portfolio securities, especially in these markets.

                                      14
<PAGE>
 
          In addition, emerging market countries' exchanges' and broker-dealers
          are generally subject to less government and exchange regulation than
          their counterparts in developed countries. Brokerage commissions,
          dealer concessions, custodial expenses and other transaction costs may
          be higher on emerging markets than in developed countries. As a
          result, the Fund has operating expenses that are expected to be higher
          than other funds investing in more established market regions.
    
          Many of the emerging market countries may be subject to a greater
          degree of economic, political and social instability than is the case
          in the United States, Canada, Australia, New Zealand, Japan and
          Western European and certain Asian countries. Such instability may
          result from, among other things; (i) popular unrest associated with
          demands for improved political, economic and social conditions, and
          (ii) internal insurgencies.      

          In certain emerging market countries governments participate to a
          significant degree, through ownership or regulation, in their
          respective economies. Action by these governments could have a
          significant adverse effect on market prices of securities and payment
          of dividends. In addition, most emerging market countries have
          experienced substantial, and in some periods extremely high, rates of
          inflation. Inflation and rapid fluctuation in inflation rates have had
          and may continue to have very negative effects on the economies and
          securities markets of certain emerging market countries. In addition,
          many emerging market countries are grappling with severe recession and
          government instability.
    
          Many of the currencies of emerging market countries have experienced
          devaluations relative to the U.S. dollar, and major devaluations have
          historically occurred in certain countries. Any devaluations in the
          currencies in which portfolio securities are denominated will have a
          detrimental impact on funds investing in emerging market countries.
          Many emerging market countries are experiencing currency exchange
          problems. Countries have and may in the future impose foreign currency
          controls and repatriation control.

RISK CONSIDERATIONS

          NON-DIVERSIFIED STATUS

          The Fund is non-diversified for 1940 Act purposes and as such may
          invest a larger percentage of its assets in individual issuers than a
          diversified investment company. In this regard, the Fund is not
          subject to the general limitation that it not invest more than 5% of
          its total assets in the securities of any one issuer. To the extent
          the Fund makes investments in excess of 5% of its assets in a
          particular issuer, its exposure to credit and market risks associated
          with that issuer is increased. However, the Fund's investments will be
          limited so as to qualify for the special tax treatment afforded
          "regulated investment companies" under the Internal Revenue Code of
          1986, as amended.

                                       16
<PAGE>
 
RISK CONSIDERATIONS

          YEAR 2000
    
          The investment advisory and management services provided by the
          Adviser and the services provided to shareholders by the Transfer
          Agent depend on the smooth functioning of their computer systems. Many
          computer software systems in use today cannot recognize the year 2000,
          but revert to 1900 or some other date, due to the manner in which
          dates were encoded and calculated. That failure could have a negative
          impact on the handling of securities trades, pricing and account
          services. The Adviser and the Transfer Agent have been actively
          working on necessary changes to their own computer systems to prepare
          for the year 2000 and expect that their systems will be adapted for
          year 2000 compliance before that date, but there can be no assurance
          that they will be successful, or that interaction with other non-
          complying computer systems will not impair their services at that
          time. The Adviser has been, and is currently in contact with each of
          its External Service Providers to evaluate their readiness for the
          year 2000. The Adviser has requested each of its External Service
          Providers to either; (i) prepare a description of its process for
          identifying date sensitive areas, its approach for implementing
          changes, its testing methodology, along with its timetable for
          completion, or (ii) certify its year 2000 compliance.      

          In addition, it is possible that the markets for securities in which
          the Fund invests may be negatively affected by computer failures
          throughout the financial services industry commencing

                                      17
<PAGE>
 
          January 1, 2000. Improperly functioning trading systems may result in
          settlement problems. In addition, corporate and governmental data
          processing errors may result in production problems for individual
          companies and create overall economic uncertainties. Earnings of
          individual issuers will be affected by remediation costs which may be
          substantial. Individual firms may further experience disruptions to
          their business due to the failure of their counterparts to address
          year 2000 problems, or could experience further disruption to the
          economy at large, which could adversely affect corporate earnings
          generally and the value of their securities. Accordingly, the Fund's
          portfolio investments may be negatively affected.

                                       18
<PAGE>
 
RISK CONSIDERATIONS

          EUROPEAN ECONOMIC AND MONETARY UNION
    
          The Fund will invest in European countries that have agreed to enter
          into the European Monetary Union (EMU). EMU is an effort by certain
          European countries to, among other things, reduce barriers between
          countries and eliminate fluctuations in their currencies. Among other
          things, EMU establishes a single European currency (the euro), which
          was introduced on January 1, 1999 and is expected to replace the
          existing national currencies of all initial EMU participants by July
          1, 2002. Upon introduction of the euro, certain securities (beginning
          with government and corporate bonds) have been redonominated in the
          euro and, thereafter trade and make dividend and other payments only
          in euros.      
    
          Like other investment companies and business organizations, including
          the companies in which the Fund invests, the Fund could be adversely
          affected: (i) if the euro, or EMU as a whole does not take effect;
          (ii) if a participating country withdraws from EMU; or (iii) if the
          computing, accounting and trading systems used by the Fund's service
          providers, or by other business entities with which the Fund or its
          service providers do business, are not capable of recognizing the euro
          as a distinct currency at the time of, and following euro conversion.

          ADVISORY AGREEMENT


          The Company and the Adviser have entered into an Investment Advisory
          and Management Agreement (the "Advisory Agreement"), under the terms
          of which the Company has employed the Adviser to manage the investment

          of its assets, to place orders for the purchase and sale of its
          portfolio securities, and to be responsible for overall management of
          the Company's business affairs, subject to control by the Board of
          Directors of the Company. The Adviser also pays certain costs of
          marketing the Fund, including sales personnel compensation, from
          legitimate profits from its investment advisory fees and other
          resources available to it. Under the Advisory Agreement, the Fund pays
          to the Adviser as compensation for the services rendered, facilities
          furnished, and expenses paid by it, the following fees:

          The Adviser has retained, at its sole expense, TCW London to provide

          Agreement the Sub-Adviser assists the Adviser in performing its
          advisory functions in respect of the Fund.      
              
          The Advisory Agreement and Sub-Advisory Agreement provide that the
          Adviser and Sub-Adviser, respectively, shall not be liable for any
          error of judgment or mistake of law or for any loss suffered by the
          Fund in connection with the matters to which the agreement relates,
          except a loss resulting from willful misfeasance, bad faith or gross
          negligence on the part of the Adviser or Sub-Adviser in the
          performance of their duties or from reckless disregard by the Adviser
          or Sub-Adviser of their duties under the agreements.

MULTIPLE CLASS STRUCTURE

          The Fund currently offers two classes of shares, Institutional Class
          shares and Class N shares. Shares of each class of the Fund represent
          an equal pro rata interest in the Fund and generally gives you the
          same voting, dividend, liquidation, and other rights. The
          Institutional Class shares are offered at the current net asset value.
          The Class N shares are also offered at the current net asset value,
          but will be subject to fees imposed under a distribution plan
          ("Distribution Plan") adopted pursuant to Rule 12b-1 under the
          Investment Company Act of 1940, as amended. Pursuant to the
          Distribution Plan, the Fund compensates its distributor at a rate
          equal to 0.25% of the average daily net assets of the Fund
          attributable to its Class N shares for distribution and related
          services. Because these fees are paid out of the Fund's Class N assets
          on an on-going basis, over time, these fees will increase the cost of
          your investment and may cost you more than paying other types of sales
          charges.

                                YOUR INVESTMENT

ACCOUNT POLICIES AND SERVICES

Buying shares
    
You pay no sales charges to invest in the Fund. Your price for Fund shares is
the Fund's net asset value per share (NAV) which is calculated as of the close
of trading on the New York Stock Exchange (usually 4:00 p.m. Eastern time) every
day the exchange is open. Your order will be priced at the next NAV calculated
after your order is accepted by the Fund. Orders received by the Fund's Transfer
Agent from dealers, brokers or other service providers after the NAV for the day
is determined will receive that same day's NAV if the orders were received by
the dealers, brokers or service providers from their customers prior to 4:00
p.m. and were transmitted to and received by the Transfer Agent prior to 8:00
a.m. Eastern time on the next day. The Fund's investments are valued based on
market value, or where market quotations are not readily available, based on
fair value as determined in good faith by the Fund's board pursuant to
procedures established by the Fund's board.

SELLING SHARES

You may sell shares at any time. Your shares will be sold at the next NAV
calculated after your order is accepted by the Fund's Transfer Agent. Any
certificates representing Fund shares being sold must be returned with your
redemption request. Your order will be processed promptly and you will generally
receive the proceeds within a week.

Before selling recently purchased shares, please note that if the Fund has not
yet collected payment for the shares you are selling, it may delay sending the
proceeds for up to fifteen days.

WRITTEN SELL ORDER

Some circumstances require written sell orders, along with signature guarantees.
These include:

 .  amounts of $100,000 or more

 .  amounts of $1,000 or more on accounts whose address has been changed within
   the last 30 days

 .  requests to send the proceeds to a payee or address different than what is on
   our records

A SIGNATURE GUARANTEE helps protect against fraud. You can obtain one from most
banks or securities dealers but not from a notary public. Please call us to
ensure that your signature guarantee will be processed correctly.

EXCHANGE PRIVILEGE

You can exchange from one Class N Galileo Fund into another. You can request
your exchange in writing or by phone. Be sure to read the current prospectus for
any Fund into which you are exchanging. Any new account established through an
exchange will have the same privileges as your original account (as long as they
are available).

THIRD PARTY TRANSACTIONS

You may buy and redeem Fund shares through certain broker-dealers and financial
organizations and their authorized intermediaries. If purchases and redemptions
of Fund shares are arranged and settlement made at an investor's election
through a registered broker-dealer, other than the Fund's distributor, that
broker-dealer may, at its discretion, charge a fee for that service.

                                      24
<PAGE>
 
LARGE REDEMPTION AMOUNTS

The Fund also reserves the right to make a "redemption in kind"  payment in
portfolio securities rather than cash  if the amount you are redeeming in any
90-day period is large enough to affect Fund operations ( for example, if it
equals more than $250,000 or represents more than 1% of the Fund's assets).

ACCOUNT STATEMENTS

Every Galileo investor automatically receives regular account statements. You'll
also be sent a yearly statement detailing the tax characteristics of any
dividends and distributions you have received.

GENERAL POLICIES

If your account falls below $1,000 as a result of redemptions and or exchanges
for six months or more, the Fund may close your account and send you the
proceeds upon 60 days' written notice.

Unless you decline telephone privileges on your New Account Form, you may be
responsible for any fraudulent telephone order as long as the Transfer Agent
takes reasonable measures to verify the order.

The Fund restricts excessive trading (usually defined as more than four
exchanges out of the Fund within a calendar year). You are limited to one
exchange of shares in the Fund during any 15-day period except investors in
401(k) and other group retirement accounts, investors who purchase shares
through certain broker-dealers and asset allocation accounts managed by the
Adviser or an affiliate. The Fund reserves the right to:

 .  refuse any purchase or exchange request that could adversely affect the Fund
   or its operations, including those from any individual or group who, in the
   Fund's view, are likely to engage in excessive trading

 .  change or discontinue its exchange privilege, or temporarily suspend this
   privilege during unusual market conditions
    
 .  delay sending out redemption proceeds for up to seven days (generally applies
   only in cases of very large redemptions, excessive trading or during unusual
   market conditions).

DISTRIBUTIONS AND TAXES

     The amount of dividends of net investment income and distributions of net
     realized long and short-term capital gains payable to shareholders will be
     determined separately for the Fund. Dividends from the net investment
     income of the Fund will be declared and paid annually. The Fund will
     distribute any net realized long or short-term capital gains at least
     annually. Your distributions will be reinvested in the Fund unless you
     instruct the Fund otherwise. There are no fees or sales charges on
     reinvestments.

     In any fiscal year in which the Fund qualifies as a regulated investment
     company and distributes to shareholders all of its net investment income
     and net capital gains, the Fund is relieved of Federal income tax.

     Generally, all dividends and capital gains are taxable whether they are
     reinvested or received in cash - unless you are exempt from taxation or
     entitled to tax deferral. Capital gains distributions may be taxable at
     different rates depending on the length of time the Fund has held the
     assets sold. Early each year, you will be notified as to the amount and
     Federal tax status of all distributions paid during the prior year.
     Distributions may also be subject to state or local taxes. The tax
     treatment of redemptions from a retirement plan account may differ from
     redemptions from an ordinary shareholder account. If you redeem shares of
     the Fund or exchange them for shares of another Galileo Fund, any gain on
     the transaction may be subject to tax. You must provide the Fund with a
     correct taxpayer identification number (generally your Social Security
     Number) and certify that you are not subject to backup withholding. If you
     fail to do so, the IRS can require the Fund to withhold 31% of your taxable
     distributions and redemptions. Federal law also requires the Fund to
     withhold 30% or the applicable tax treaty rate from dividends paid to
     nonresident alien, non-U.S. partnership and non-U.S. corporation
     shareholder accounts.

     This is a brief summary of some of the tax laws that affect your investment
     in the Fund. Please see the Statement of Additional Information and your
     tax adviser for further information.

          FINANCIAL HIGHLIGHTS


          The financial highlights table is intended to help you understand the
          Fund's financial performance for the fiscal years indicated.  Certain
          information reflects financial results for a single Fund share.
          "Total return" shows how much your investment in the Institutional
          Class shares of the Fund would have increased (or decreased) during
          each period, assuming you had reinvested all dividends and
          distributions (Class N shares of the Fund commenced operations on
          March 1, 1999).  These figures have been audited by Deloitte & Touche
          LLP, whose report, along with Company's financial statements, are
          included in the annual report, which is available upon request.

INVESTMENT OBJECTIVES AND PRINCIPAL STRATEGIES
- ----------------------------------------------

 
The Fund is affected by changes in the economy, or in securities and other
markets. Additionally, changes in interest rates will affect not only the
current return on the Fund, but the value of the capital investment will most
likely fluctuate up or down. There is also the possibility that investment
decisions the Adviser makes will not accomplish what they were designed to
achieve or that companies in which the Fund invests will have disappointing
performance or not pay their debts.

      TCW Galileo Funds, Inc.            Investment Objectives                        Principal Investment Strategies 
- ----------------------------------------------------------------------------------------------------------------------------------
TCW Galileo High Yield Bond Fund         Maximize current income and achieve          Invests in high yield bonds, commonly known as
                                         above average total return turn              "junk" bonds.
                                         consistent with reasonable risk over
                                         a full market cycle
- ----------------------------------------------------------------------------------------------------------------------------------
</TABLE>

Under adverse market conditions, the Fund could invest some or all of its assets
in money market securities. Although the Fund would do this only when seeking to
avoid losses, it could have the effect of reducing the benefit from any upswing
in the market.

                                       3
<PAGE>
 
PRINCIPAL RISKS
- ---------------
 
Risk is the chance that you will lose money on your investment or that it will
not earn as much as you expect. In general, the greater the risk, the more money
your investment can earn for you and the more you can lose. Since shares of the
Fund represent an investment in securities with fluctuating market prices, the
value of fund shares will vary as the value of the Fund's portfolio securities
increases or decreases. Therefore, the value of an investment in the Fund could
go down as well as up. All investments are subject to:
    
 .     MARKET RISK      
 
      There is the possibility that the returns from the types of securities in
      which the Fund invests will underperform returns from the various general
      securities markets or different asset classes. Different types of
      securities tend to go through cycles of outperformance and
      underperformance in comparison to the general securities markets.

 .     SECURITIES SELECTION RISK
 
      There is the possibility that the specific securities held in the Fund's
      portfolio will underperform the other funds in the same asset class or
      benchmarks that are representative of the general performance of the asset
      class because of the portfolio manager's choice of securities.
 
Because the Fund is a fixed income fund, the Fund may also be subject (in
varying degrees) to the following additional risks:
 
 .     CREDIT RISK
 
      There is the possibility that the Fund could lose money if an issuer is
      unable to meet its financial obligations such as the payment of principal
      and/or interest on an instrument, or goes bankrupt. The Fund is subject to
      great credit risk because it invests in high yield bond funds, which are
      commonly referred to as "junk bonds."
 
 .     INTEREST RATE RISK
 
      There is the possibility that the value of the Fund's portfolio
      investments may fall since fixed income securities generally fall in value
      when interest rates rise. The longer the term of a fixed income
      instrument, the more sensitive it will be to fluctuations in value from
      interest rate changes. Changes in interest rates may have a significant
      effect on the Fund, because the Fund may hold securities with long terms
      to maturity. 
 

                                       4
<PAGE>
 
PRINCIPAL RISKS
- ---------------
 
 .     JUNK BONDS
 
      These bonds are speculative in nature. They are usually issued by
      companies without long track records of sales and earnings, or by those
      companies with questionable credit strength. These bonds are considered
      "below investment grade." The Fund primarily invests in below investment
      grade corporate securities.
 
 .     FOREIGN INVESTING RISK
     
      There is the likelihood that foreign investments may be riskier than U.S.
      investments because of a lack of political stability, foreign controls on
      investment and currency exchange rates, fluctuations in currency exchange
      rates, withholding taxes and lack of adequate company information. The
      Fund is subject to foreign investing risk because it may invest a portion
      of its assets in foreign company securities. If it invests in emerging
      markets countries, and it may, these risks are more pronounced. In
      addition, because foreign securities generally are denominated and pay
      dividends or interest in foreign currencies, and the Fund may hold various
      foreign currencies, the value of the net assets of the Fund as measured in
      U.S. dollars can be affected favorably or unfavorably by changes in
      exchange rates.     
 
 .     LIQUIDITY RISK
 
      There is the possibility that the Fund may lose money or be prevented from
      earning capital gains if it cannot sell a security at the time and price
      that is most beneficial to the Fund. The Fund is subject to liquidity
      risks because it invests in high yield bonds, mortgage-backed securities
      or foreign or emerging markets securities, which have all experienced
      periods of illiquidity.
 
The Fund may be more susceptible to some of these risks than others, as noted in
the description of the Fund. A more detailed explanation of these risks is
presented under the "Risk Considerations" section at page 12. 

Your investment is not a bank deposit, and it is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE SUMMARY
- -------------------
     
The two tables below show the Fund's annual returns and its long-term
performance with respect to its Institutional Class shares (Class N shares of
the Fund commenced operations on March 1, 1999). The first table shows you how
the Fund's performance has varied from year to year. The second compares the
Fund's performance over time to that of a broad-based securities index. Both
tables assume reinvestment of dividends and distributions. The performance
information includes performance of the predecessor limited partnership, which
was managed by a predecessor of TCW Funds Management, Inc. using the same
investment strategy as the Fund. The performance of the partnership was
calculated using performance standards applicable to private investment
partnerships which take into account all elements of total return and reflect
the deduction of all fees and expenses of operation. The predecessor limited
partnership, was not registered under the Investment Company Act of 1940 ("1940
Act") and therefore, was not subject to certain investment restrictions imposed
by the 1940 Act and Subchapter M of the Internal Revenue Code of 1986, as
amended. If the limited partnership had been registered under the 1940 Act its
performance could have been adversely affected. As with all mutual funds, past
performance is not a prediction of future results.

Expense Example

This Example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other mutual funds.

This Example shows what you could pay in expenses over time. It uses the same
hypothetical conditions other funds use in their prospectuses: $10,000 Initial
Investment, 5% total return each year and no changes in expenses. The figures
shown would be the same whether or not you sold your shares at the end of a
period. Because actual return and expenses will be higher or lower, the Example
is for comparison purposes only.

                       TCW Galileo High Yield Bond Fund

 . INVESTMENT OBJECTIVES/APPROACH
- --------------------------------
    
The Fund seeks to maximize income and achieve above average total return
consistent with reasonable risk over a full market cycle. To pursue this goal,
it invests (except when maintaining a temporary defensive position) at least 65%
of the value of its total assets in high yield/below investment grade bonds,
commonly known as "junk" bonds. It also invests in other high yield fixed income
securities, including convertible and non-convertible debt securities.     

In managing the Fund's investments, the Adviser places emphasis on securities at
the lower-risk end of the high yield bond/below investment grade spectrum. These
securities are issued by companies that the Adviser believes have stable to
improving business prospects. The Adviser's investment approach also emphasizes
consistent and high current income. It attempts to reduce the Fund's investment
risk through diversification and by analysis of:

 .  each issuer

 .  each issuer's ability to make timely payments of principal and interest

 .  broad economic trends and corporate developments

Mark L. Attanasio, Mark D. Senkpiel, and Melissa V. Weiler are the Fund's
portfolio managers.


Concepts to understand
- ----------------------

Junk bonds are bonds that have a  credit rating of BB or lower by rating
agencies such as Moody's Investors Service, Inc. and Standard & Poor's
Corporation.  These bonds are often issued by companies without long track
records of sales and earnings, or by those companies with questionable credit
strength.  In the event of a prepayment problem by the issuer of these bonds,
they will only be paid if there is anything left after the payment of senior
debt, such as bank loans and investment grade bonds.

Junk bonds are considered to be mostly speculative in nature.  This gives the
Fund more credit risk than Galileo's other fixed income funds, but also gives it
the potential for higher returns

                                       9
<PAGE>
 
 . MAIN RISKS
- ------------

The primary risks affecting this Fund are "credit risk," "interest rate risk,"
"liquidity risk" and, to a lesser extent, "foreign investing risk."

Credit risk refers to the likelihood that the Fund could lose money if an issuer
is unable to meet its financial obligations, such as the payment of principal
and/or interest on an instrument, or goes bankrupt. This Fund is subject to high
credit risk, because it invests primarily in high yield/below investment grade
bonds. Debt securities that are rated below investment grade are considered to
be speculative; they are also commonly known as "junk" bonds. This is especially
true during periods of economic uncertainty or during economic downturns.
Interest rate risk refers to the possibility that the value of the Fund's
portfolio investments may fall since fixed income securities generally fall in
value when interest rates rise. The longer the term of a fixed income
instrument, the more sensitive it will be to fluctuations in value from interest
rate changes. Changes in interest rates may have a significant effect on this
Fund, because it may hold securities with long terms to maturity. Liquidity risk
refers to the possibility that the Fund may lose money or be prevented from
earning capital gains if it cannot sell a security at the time and price that is
most beneficial to the Fund. Because high yield bonds may be less liquid than
higher quality securities, the Fund may be more susceptible to liquidity risk
than funds that invest in higher quality investments. A security whose credit
rating has been lowered may be particularly difficult to sell. Because the Fund
may invest a portion of its assets in foreign company securities, it may be
subject to foreign investing risk. Foreign investing risk refers to the
likelihood that foreign investments may be riskier than U.S. investments because
of many factors, some of which include:

 .  a lack of political or economic stability

 .  foreign controls on investment and currency exchange rates

 .  withholding taxes

 .  a lack of adequate company information

The risks of foreign investing are even more pronounced if the Fund invests in
emerging markets. In addition, securities traded only through foreign markets
may be more volatile and are often harder to sell. Volatility is a way to
measure the changes in the price of a single security or an entire portfolio.
Large and frequent price changes indicate 

                                       10
<PAGE>
     
higher volatility, which generally indicate that there is a greater chance you
could lose money over the short term. The Fund is also subject to foreign
currency risk. Because foreign securities are generally denominated and pay
dividends or interest in foreign currencies, the value of the net assets of the
Fund as measured in the U.S. dollars will be affected favorably or unfavorably
by changes in exchange rates.      

The Fund seeks to earn additional income by making loans of its portfolio
securities to brokers, dealers and other financial institutions. The loans will
be secured at all times by cash and liquid high-grade debt obligations. As with
any extension of credit, there are risks of delay in recovery and in some cases
even loss of rights in the collateral should the borrower fail financially.
    
The Fund may engage in active portfolio management which may result in increased
Fund transaction expenses and have tax consequences such as increased realized 
gains for investors.

================================================================================

 . RISK CONSIDERATIONS
- ---------------------


Please consider the following risks before investing in the Fund.

Various market risks can affect the price or liquidity of an issuer's
securities. Adverse events occurring with respect to an issuer's performance or
financial position can depress the value of the issuer's securities. The
liquidity in a market for a particular security will affect its value and may be
affected by factors relating to the issuer and the depth of the market for that
security. Other market risks that can affect value include a market's current
attitudes about type of security, market reactions to political or economic
events, and tax and regulatory effects (including lack of adequate regulations
for a market or particular type of instrument). Market restrictions on trading
volume can also affect price and liquidity.

Prices of most securities tend to be more volatile in the short-term. Therefore
an investor who trades frequently or redeems in the short-term is more likely to
incur loss than an investor who holds investments for the longer term. The fewer
the number of issuers in which a Fund invests, the greater the potential
volatility of its portfolio.
    
The Adviser may temporarily invest up to 100% of the Fund's assets in high
quality, short-term money market instruments if it believes adverse economic or
market conditions, such as excessive volatility or sharp market declines,
justify taking a defensive investment posture. If the Fund attempts to limit
investment risk by temporarily taking a defensive investment position, it may be
unable to pursue its investment objective during that time, and it may miss out
on some or all of an upswing in the securities markets.     

General Investment Risk
- -----------------------

Since shares of the Fund represent an investment in securities with fluctuating
market prices, the value of Fund shares will vary as the value of the Fund's
portfolio securities increases or decreases.  Therefore, the value of an
investment in the Fund could go down as well as up.  This is also true for funds
that invest primarily in fixed income securities.  High credit quality
investments also react in value to interest rate changes.

                                       12
<PAGE>
 
 . RISK CONSIDERATIONS
- ---------------------

Fixed Income Securities
- -----------------------

Fixed income securities are subject to various risks. The two primary (but not
exclusive) risks affecting fixed income instruments are "credit risk" and
"interest rate risk." These risks can affect a security's price volatility to
varying degrees, depending upon the nature of the instrument. In addition, the
depth and liquidity of the market for an individual or class of fixed income
security can also affect its price and, hence, the market value of a Fund.

"Credit risk" refers to the likelihood that an issuer will default in the
payment of principal and/or interest on an instrument. Financial strength and
solvency of an issuer are the primary factors influencing credit risk. In
addition, lack of or inadequacy of collateral or credit enhancements for a fixed
income security may affect its credit risk. Credit risk of a security may change
over its life and securities which are rated by rating agencies are often
reviewed and may be subject to downgrades.

The Fund's portfolio consists primarily of below investment grade corporate
securities that are commonly known as junk bonds. Generally, lower-rated debt
securities provide a higher yield than higher rated debt securities of similar
maturity but are subject to greater credit risk than higher rated securities of
similar maturity. These securities are regarded as predominantly speculative
with respect to the issuer's continuing ability to meet principal and interest
payments. Because investment in lower quality securities involves greater
investment risk, achievement of the Fund's investment objective will be more
dependent on the Adviser's analysis than would be the 

                                       13
<PAGE>
 
case if the Fund were investing in higher quality bonds. In addition, lower
quality securities may be more susceptible to real or perceived adverse economic
and individual corporate developments than would investment grade bonds.
Moreover, the secondary trading market for lower quality securities may be less
liquid than the market for investment grade bonds. This potential lack of
liquidity may make it more difficult for the Adviser to value accurately certain
portfolio securities.

"Interest rate risk" refers to the change in value of debt instruments
associated with changes in interest rates. Interest rate changes may affect the
value of a fixed income security directly (especially in the case of fixed rate
securities) and indirectly (especially in the case of adjustable rate
securities). In general, rises in interest rates will negatively impact the
value of fixed rate securities and falling interest rates will have a positive
effect on value. The degree to which a security's price will change as a result
of changes in interest rates is measured by its "duration." For example, the
price of a bond with a 5 year duration would be expected under normal market
conditions to decrease 5% for every 1% increase in interest rates. Generally,
securities with longer maturities have a greater duration and thus are subject
to greater price volatility from changes in interest rates. Adjustable rate
instruments also react to interest rate changes in a similar manner although
generally to a lesser degree (depending, however, on the characteristics of the
reset terms, including the index chosen, frequency of reset and reset caps or
floors, among other things).

 . RISK CONSIDERATIONS
- ---------------------


Foreign Investing
- -----------------


Investment in foreign securities involves special risks in addition to the usual
risks inherent in domestic investments. These include: political or economic
instability; the unpredictability of international trade patterns; the
possibility of foreign governmental actions such as expropriation,
nationalization or confiscatory taxation; the imposition or modification of
currency exchange or foreign investment controls; the imposition of withholding
taxes on dividends, interest and gains; price volatility; and fluctuations in
currency exchange rates. These risks are more pronounced in emerging market
countries.

As compared to United States companies, foreign issuers generally disclose less
financial and other information publicly and are subject to less stringent and
less uniform accounting, auditing and financial reporting standards. Foreign
countries typically impose less thorough regulations on brokers, dealers, stock
exchanges, insiders and listed companies than does the United States, and
foreign securities markets may be less liquid and more volatile than domestic
markets. Investment in foreign securities involves higher costs than investment
in U.S. securities, including higher transaction and custody costs as well as
the imposition of additional taxes by foreign governments. In addition, security
trading practices abroad may offer less protection to investors such as the
Fund. Settlement of transactions in some foreign markets may be delayed or may
be less frequent than in the U.S., which could affect the liquidity of the
Fund's portfolio. Also, it may be more difficult to obtain and enforce legal
judgments against foreign corporate issuers than against

                                       15
<PAGE>
 
domestic issuers and it may be impossible to obtain and enforce judgments
against foreign governmental issuers.
    
Because foreign securities generally are denominated and pay dividends or
interest in foreign currencies, and the Fund may hold various foreign currencies
from time to time, the value of the net assets of the Fund as measured in U.S.
dollars can be affected favorably or unfavorably by changes in exchange rates.
Generally, currency exchange transactions will be conducted on a spot (i.e.,
cash) basis at the spot rate prevailing in the currency exchange market. The
cost of currency exchange transactions will generally be the difference between
the bid and offer spot rate of the currency being purchased or sold. In order to
protect against uncertainty in the level of future foreign currency exchange
rates, the Fund is authorized to enter into foreign currency futures and forward
contracts. However, it is not obligated to do so and, depending on the
availability and cost of these devices, the Fund may be unable to use foreign
currency futures and forward contract to protest against currency uncertainty.
Please see the Statement of Additional Information for further information.    

The forward currency market for the purchase or sale of U.S. dollars in some
countries is not highly developed, and in certain countries, there may be no
such market. If a devaluation of a currency is generally anticipated, the Fund
may not be able to contract to sell the currency at an exchange rate more
advantageous than that which would prevail after the anticipated amount of
devaluation, particularly as regards forward contracts for local currencies in
view of the relatively small, inactive or even non-existent market for these
contracts. In the event the Fund holds securities denominated in a currency that
suffers a devaluation, the Fund's net asset value will suffer corresponding
reductions. In this regard, in December 1994, the Mexican government determined
to allow the Mexican peso to trade freely against the U.S. dollar rather than
within a controlled band, which resulted in a significant devaluation of the
Mexican peso against the dollar. Further, in July 1997, the Thai and Philippine
governments allowed the baht and peso, respectively, to trade freely against the
U.S. dollar resulting in a sharp devaluation of both currencies, and in 1998
Russia did the same, causing a sharp devaluation of the ruble.

 . RISK CONSIDERATIONS
- ---------------------


Year 2000
- ---------

    
The investment advisory and management services provided by the Adviser and the
services provided to shareholders by the Transfer Agent depend on the smooth
functioning of their computer systems. Many computer software systems in use
today cannot recognize the year 2000, but revert to 1900 or some other date, due
to the manner in which dates were encoded and calculated. That failure could
have a negative impact on the handling of securities trades, pricing and account
services. The Adviser and the Transfer Agent have been actively working on
necessary changes to their own computer systems to prepare for the year 2000 and
expect that their systems will be adapted for year 2000 compliance before that
date, but there can be no assurance that they will be successful, or that
interaction with other non-complying computer systems will not impair their
services at that time. The Adviser has been, and is currently in contact with,
each of its External Service Providers to evaluate their readiness for the year
2000. The Adviser has requested each of its External Service Providers to either
(i) prepare a description of its process for identifying date sensitive areas,
its approach for implementing changes, its testing methodology, along with its
timetable for completion, or (ii) certify as to its year 2000 compliance.      

In addition, it is possible that the markets for securities in which the Fund
invests may be negatively affected by computer failures throughout the financial
services industry commencing January 1, 2000. Improperly functioning trading
systems may result in settlement problems. In addition, corporate and
governmental data processing errors may result in production problems for
individual companies and create overall economic uncertainties. Earnings of
individual issuers

                                       17
<PAGE>
 
will be affected by remediation costs which may be substantial. Individual firms
may further experience disruptions to their business due to the failure of their
counterparts to address approaching year 2000 problems, or could experience
further disruption to the economy at large, which could adversely affect
corporate earnings generally and the value of their securities. Accordingly, the
Fund's portfolio investments may be negatively affected.

                                       18
<PAGE>
 
 . RISK CONSIDERATIONS
- ---------------------


European Economic and Monetary Union
- ------------------------------------

    
The Fund may invest in European countries that have agreed to enter into the
European Monetary Union (EMU). EMU is an effort by certain European countries
to, among other things, reduce barriers between countries and eliminate
fluctuations in their currencies. Among other things, EMU establishes a single
European currency (the euro), which was introduced on January 1, 1999 and is
expected to replace the existing national currencies of all initial EMU
participants by July 1, 2002. Upon introduction of the euro, certain securities
(beginning with government and corporate bonds) have been redonominated in
the euro and, thereafter trade and make dividend and other payments only in
euros.      
    
Like other investment companies and business organizations, including the
companies in which the Fund invests, the Fund could be adversely affected: (i)
if the euro, or EMU as a whole does not take effect; (ii) if a participating
country withdraws from EMU; or (iii) if the computing, accounting and trading
systems used by the Fund's service providers, or by other business entities with
which the Fund or its service providers do business, are not capable of
recognizing the euro as a distinct currency at the time of, and following euro
conversion.

The Advisory Agreement provides that the Adviser shall not be liable for any
error of judgment or mistake of law or for any loss suffered by the Fund in
connection with the matters to which the agreement relates, except a loss
resulting from willful misfeasance, bad faith, gross negligence on the part of
the Adviser in the performance of its duties or from reckless disregard by the
Adviser of its duties under the agreement.

 . MULTIPLE CLASS STRUCTURE
- --------------------------

The Fund currently offers two classes of shares, Institutional Class shares and
Class N shares. Shares of each class of the Fund represents an equal pro rata
interest in that Fund and generally gives you the same voting, dividend,
liquidation, and other rights. The Institutional Class shares are offered at the
current net asset value. The Class N shares are also offered at the current net
asset value, but will be subject to fees imposed under a distribution plan
("Distribution Plan") adopted pursuant to Rule 12b-1 under the Investment
Company Act of 1940, as amended. Pursuant to the Distribution Plan, the Fund
compensates its distributor at a rate equal to 0.25% of the average daily net
assets of the Fund attributable to its Class N shares for distribution and
related services are paid out of the 

                                       21
<PAGE>
 
Fund's Class N shares for distribution and related services. Because these fees
are paid out of the Fund's Class N assets on an on-going basis, over time, these
fees will increase the cost of your investment and may cost you more than paying
other types of sales charges.

 . ACCOUNT POLICIES AND SERVICES
- -------------------------------

Buying shares
    
You pay no sales charges to invest in the Fund. Your price for Fund shares is
the Fund's net asset value per share (NAV) which is calculated as of the close
of trading on the New York Stock Exchange (usually 4:00 p.m. Eastern time) every
day the exchange is open. Your order will be priced at the next NAV calculated
after your order is accepted by the Fund. Orders received by the Fund's Transfer
Agent from dealers, brokers or other service providers after the NAV for the day
is determined, will receive that same day's NAV if the orders were received by
the dealers, brokers or service providers from their customers prior to 4:00
p.m. and were transmitted to and received by the Transfer Agent prior to 8:00
a.m. Eastern time on the next day. The Fund's investments are valued based on
market value, or where market quotations are not readily available, based on
fair value as determined in good faith by the Fund pursuant to procedures
established by the Fund's Board.

Selling shares

You may sell shares at any time. Your shares will be sold at the next NAV
calculated after your order is accepted by the Fund's Transfer Agent. Any
certificates representing Fund shares being sold must be returned with your
redemption request. Your order will be processed promptly and you will generally
receive the proceeds within a week.

Before selling recently purchased shares, please note that if the Fund has not
yet collected payment for the shares you are selling, it may delay sending the
proceeds for up to fifteen days.

Written sell order

Some circumstances require written sell orders, along with signature guarantees.
These include:

 .  amounts of $100,000 or more

 .  amounts of $1,000 or more on accounts whose address has been changed within
   the last 30 days

 .  requests to send the proceeds to a payee or address different than what is on
   our records

A signature guarantee helps protect against fraud. You can obtain one from most
banks or securities dealers but not from a notary public. Please call us to
ensure that your signature guarantee will be processed correctly.

         

         

Exchange privilege

You can exchange from one Class N Galileo Fund into another. You can request
your exchange in writing or by phone. Be sure to read the current prospectus for
any Fund into which you are exchanging. Any 

                                       24
<PAGE>
 
new account established through an exchange will have the same privileges as
your original account (as long as they are available).

Third Party Transactions
    
You may buy and redeem Fund shares through certain broker-dealers and financial
organizations and their authorized intermediaries. If purchases and redemptions
of Fund shares are arranged and settlement is made at an investor's election
through a registered broker-dealer, other than the Fund's distributor, that
broker-dealer may, at its discretion, charge a fee for that service.      

Account statements

Every investor automatically receives regular account statements. You will also
be sent a yearly statement detailing the tax characteristics of any dividends
and distributions you have received.

LARGE REDEMPTION AMOUNTS
- ------------------------

The Fund also reserves the right to make a "redemption in kind"  payment in
portfolio securities rather than cash  if the amount you are redeeming in any
90-day period is large enough to affect Fund operations ( for example, if it
equals more than $250,000 or represents more than 1% of the Fund's assets).


General policies

If your account falls below $1,000 as a result of redemptions and or exchanges
for six months or more, the Fund may close your account and send you the
proceeds upon 60 days' written notice.

Unless you decline telephone privileges on your New Account Form, you may be
responsible for any fraudulent telephone order as long as the Transfer Agent
takes reasonable measures to verify the order.
    
The Fund restricts excessive trading (usually defined as more than four
exchanges out of the Fund within a calendar year). You are limited to one
exchange of shares in the Fund during any 15-day period except investors in
401(k) and other group retirement accounts, investors who purchase shares
through certain broker-dealers, and asset allocation accounts managed by the
Adviser or an affiliate. The Fund reserves the right to:      



                                       25
<PAGE>
 
 .  refuse any purchase or exchange request that could adversely affect the Fund
   or its operations, including those

 .  from any individual or group who, in the Fund's view, are likely to engage in
   excessive trading

 .  change or discontinue its exchange privilege, or temporarily suspend this
   privilege during unusual market conditions delay sending out redemption
   proceeds for up to seven days (generally applies only in cases of very large
   redemptions, excessive trading or during unusual market conditions)

 . DISTRIBUTIONS AND TAXES
- -------------------------

The amount of dividends of net investment income and distributions of net
realized long and short-term capital gains payable to shareholders will be
determined separately for the Fund. Dividends from the net investment income of
the Fund will be declared and paid monthly. The Fund will distribute any net
realized long or short-term capital gains at least annually. Your distributions
will be reinvested in the fund unless you instruct the fund otherwise. There are
no fees or sales charges on reinvestments.

In any fiscal year in which the Fund qualifies as a regulated investment company
and distributes to shareholders all of their net investment income and net
capital gains, the Fund is relieved of federal income tax.

Generally, all dividends and capital gains are taxable whether they are
reinvested or received in cash unless you are exempt from taxation or entitled
to tax deferral. Capital gains distributions may be taxable at different rates
depending on the length of time the Fund has held the assets sold. Early each
year, you will be notified as to the amount and federal tax status of all
distributions paid during the prior year. Distributions may also be subject to
state or local taxes. The tax treatment of redemptions from a retirement plan
account may differ from redemptions from an ordinary shareholder account. If you
redeem shares of the Fund or exchange them for shares of another fund, any gain
on the transaction may be subject to tax. You must provide the Fund with a
correct taxpayer identification number (generally your Social Security Number)
and certify that you are not subject to backup withholding. If you fail to do
so, the IRS can require the Fund to withhold 31% of your taxable distributions
and redemptions. Federal law also requires the Fund to withhold 30% or the
applicable tax treaty rate from dividends paid to nonresident alien, non-U.S.
partnership and non-U.S. corporation shareholder accounts.

This is a brief summary of some of the tax laws that affect your investment in
the Fund. Please see the Statement of Additional Information and your tax
adviser for further information.

 . FINANCIAL HIGHLIGHTS
- ----------------------

The financial highlights table is intended to help you understand the Fund's
financial performance for the fiscal years indicated. Certain information
reflects financial results for a single Fund share. "Total return" shows how
much your investment in the Institutional Class shares of the Fund would have
increased (or decreased) during each period, assuming you had reinvested all
dividends and distributions (Class N shares of the Fund commenced operations on
March 1, 1999). These figures have been audited by Deloitte & Touche LLP, whose
report, along with Company's financial statements, are included in the annual
report, which is available upon request.

Investment Objectives and Principal Strategies
- ----------------------------------------------      
 
The Fund is affected by changes in the economy, or in securities and other
markets. There is also the possibility that investment decisions the Adviser
makes will not accomplish what they were designed to achieve or that companies
in which the Fund invests will have disappointing performance or not pay their
debts.

Under adverse market conditions, the Fund could invest some or all of its assets
in money market securities.  Although the Fund would do this only in seeking to
avoid losses, it could have the effect of reducing the benefit from any upswing
in the market.

Principal Risks
- --------------- 
Risk is the chance that you will lose money on your investment or that it will
not earn as much as you expect. In general, the greater the risk, the more money
your investment can earn for you and the more you can lose. Since shares of the
Fund represent an investment in securities with fluctuating market prices, the
value of Fund shares will vary as the Fund's portfolio securities increase or
decrease in value. Therefore, the value of an investment in the Fund could go
down as well as up. All investments are subject to:      
     
 .  MARKET RISK      
 
   There is the possibility that the returns from the types of securities in
   which the Fund invests will underperform returns from the various general
   securities markets or different asset classes. Different types of securities
   tend to go through cycles of outperformance and underperformance in
   comparison to the general securities markets.
 
 .  SECURITIES SELECTION RISK
 
   There is the possibility that the specific securities held in the Fund's
   portfolio will underperform other funds in the same asset class or
   benchmarks that are representative of the general performance of the asset
   class because of the portfolio manager's choice of securities.
    
 .  PRICE VOLATILITY
 
   There is the possibility that the value of the Fund's portfolio will change
   as the prices of its investments go up or down. Although stocks offer the
   potential for greater long-term growth than most fixed income securities,
   stocks generally have higher short-term volatility.
 
The Fund may also be subject to the following risk:
     
 .  FOREIGN INVESTING RISK
 
   There is the likelihood that foreign investments may be riskier than U.S.
   investments because of a lack of political stability, foreign controls on
   investment and currency exchange rates, fluctuations in currency exchange
   rates, withholding taxes, and a lack of adequate company information. The
   Fund is subject to foreign investing risk because it may invest a portion of
   its assets in foreign company securities. In addition, because foreign
   securities generally are denominated and pay dividends or interest in foreign
   currencies, and the Fund may hold various foreign currencies, the value of
   the net assets of the Fund as measured in U.S. dollars can be affected
   favorably or unfavorably by changes in exchange rates.     

                                       4
<PAGE>
    
Principal Risks      
- ---------------

Because the Fund is non-diversified for 1940 Act purposes, it may invest more
than 5% of its total assets in the securities of any one issuer. Consequently,
its exposure to credit and market risks associated with that issuer is
increased. 

Your investment is not a bank deposit, and it is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency.

Performance Summary 
- -------------------     
     
The two tables below show the Fund's annual returns and its long-term
performance with respect to its Institutional Class shares (Class N shares of
the Fund commenced operations on March 1, 1999). The first table shows you how
the Fund's performance has varied from year to year. The second compares the
Fund's performance over time to that of a broad-based securities index. Both
tables assume reinvestment of dividends and distributions. The performance
information includes performance of the predecessor limited partnership, which
was managed by a predecessor of TCW Funds Management, Inc. using the same
investment strategy as the Fund. The performance of the partnership was
calculated using performance standards applicable to private investment
partnerships which take into account all elements of total return and reflect
the deduction of all fees and expenses of operation. The predecessor limited
partnership, was not registered under the Investment Company Act of 1940 ("1940
Act") and therefore, was not subject to certain investment restrictions imposed
by the 1940 Act and Subchapter M of the Internal Revenue Code of 1986, as
amended. If the limited partnership had been registered under the 1940 Act its
performance could have been adversely affected. As with all mutual funds, past
performance is not a prediction of future results.

 Funds Expenses and Expense Example      
- -----------------------------------

As an investor, you pay certain fees and expenses in connection with the Fund,
which are described in the table below. Annual fund operating expenses are paid
out of Fund assets, so their effect is included in the share price. The Class N
shares of the Fund have no sales charge (load), but are subject to Rule 12b-1
distribution fees.

EXPENSE EXAMPLE

This Example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other mutual funds.
    
This Example shows what you could pay in expenses over time. It uses the same
hypothetical conditions other funds use in their prospectuses: $10,000 Initial
Investment, 5% total return each year and no changes in expenses. The figures
shown would be the same whether or not you sold your shares at the end of a
period. Because actual return and expenses will be higher or lower, the Example
is for comparison purposes only.

                       --------------------------------

       INVESTMENT OBJECTIVES/APPROACH
       ------------------------------
    
          The Fund seeks long-term capital appreciation. To pursue this goal,
          the Fund invests primarily in equity securities of large
          capitalization companies. The securities include common and preferred
          stock and convertible securities. The Fund will invest (except when
          maintaining a temporary defensive position) at least 65% of the
          value of its total assets in publicly traded equity securities of
          companies with a market capitalization of greater than $3 billion at
          the time of purchase. The Fund will invest mostly in "value
          companies."      
    
          In managing the Fund's investments, the Adviser seeks to invest in
          attractively valued equity securities of companies where the return on
          invested capital is improving.  The Adviser utilizes bottom-up
          fundamental research to identify these companies.  The Adviser
          performs fundamental research by using techniques such as:      

          .  making company visits
          .  financial screening to identify companies
          .  maintaining a disciplined approach to stock selection and portfolio
             construction

          The Adviser will use both quantitative and qualitative screen-ing
          criteria to supplement the scope of its fundamental research.

          Thomas K. McKissick is the Fund's portfolio manager.


Concepts to understand
- ----------------------

Large capitalization companies are established companies that are considered 
known quantities. Large capitalization companies often have the resources to 
weather economic shifts, though they can be slower to innovate than small 
companies.  
   
Value companies are companies that appear underpriced according to certain
financial measurements of their intrinsic worth or business prospects (such as
price-to-earnings or price-to-book ratios). Because a stock can remain
undervalued for years, value investors often look for factors that could trigger
a rise in price.      

                                       9
<PAGE>
 
MAIN RISKS
- ----------

          The Fund holds primarily stocks, which may go up or down in value,
          sometimes rapidly and unpredictably. Although stocks offer the
          potential for greater long-term growth than most fixed income
          securities, stocks generally have higher short-term volatility.  In
          addition, the Fund may hold convertible debt securities.  Many
          convertible debt securities are rated below investment grade and are
          considered speculative by rating agencies as to repayment of principal
          and interest.

          The primary risk affecting this Fund is "price volatility." Price
          volatility refers to the possibility that the value of the Fund's
          portfolio will change as the prices of its investments go up or down.
          This Fund may be less susceptible to price volatility than funds that
          invest in the securities of small companies. This is especially true
          during periods of economic uncertainty or during economic downturns.

          The Fund may invest some assets in options.  This practice is used
          primarily to hedge the Fund's portfolio, but it may be used to
          increase returns; however, this practice sometimes may reduce returns
          or increase volatility.

          The Fund seeks to earn additional income by making loans of its
          portfolio securities to brokers, dealers and other financial
          institutions.  The loans will be secured at all times by cash and
          liquid high grade debt obligations.  As with any extension of credit,
          there are risks of delay in recovery and in some cases even loss of
          rights in the collateral should the borrower fail financially.
    
          The Fund may engage in active portfolio management which may result in
          increased Fund transaction expenses and have tax consequences such as
          increased realized gains for investors.

- --------------------------------------------------------------------------------


RISK CONSIDERATION
- ------------------

          Please consider the following risks before investing in the Fund.

          Various market risks can affect the price or liquidity of an issuer's
          securities.  Adverse events occurring with respect to an issuer's
          performance or financial position can depress the value of the
          issuer's securities.  The liquidity in a market for a particular
          security will affect its value and may be affected by factors relating
          to the issuer, as well as the depth of the market for that security.
          Other market risks that can affect value include a market's current
          attitudes about types of securities, market reactions to political or
          economic events, and tax and regulatory effects (including lack of
          adequate regulations for a market or particular type of instrument).
          Market restrictions on trading volume can also affect price and
          liquidity.
    
          Prices of many securities tend to be more volatile in the short-term.
          Therefore, an investor who trades frequently or redeems in the short-
          term is more likely to incur loss than an investor who holds
          investments for the longer term.  The fewer the number of issuers in
          which the Fund invests, the greater the potential volatility of its
          portfolio.     
    
          TCW may temporarily invest up to 100% of the Fund's assets in high
          quality, short-term money market instruments if it believes adverse
          economic or market conditions, such as excessive volatility or sharp
          market declines, justify taking a defensive investment posture. If the
          Fund attempts to limit investment risk by temporarily taking a
          defensive investment position, it may be unable to pursue its
          investment objective during that time, and it may miss out on some or
          all of an upswing in the securities markets.      

General Investment Risk
- -----------------------

Since shares of the Fund represent an investment in securities with fluctuating 
market prices, the value of Fund shares will vary as the value of the Fund's 
portfolio securities increases or decreases. Therefore, the value of an 
investment in the Fund could go down as well as up.

RISK CONSIDERATIONS
- -------------------

    
Foreign Investing      
- -----------------

          Investment in foreign securities involves special risks in addition to
          the usual risks inherent in domestic investments.  These include:
          political or economic instability; the unpredictability of
          international trade patterns; the possibility of foreign governmental
          actions such as expropriation, nationalization or confiscatory
          taxation; the imposition or modification of foreign currency or
          foreign investment controls; the imposition of withholding taxes on
          dividends, interest and gains; price volatility; and fluctuations in
          currency exchange rates.
    
          As compared to United States companies, foreign issuers generally
          disclose less financial and other information publicly and are subject
          to less stringent and less uniform accounting, auditing and financial
          reporting standards. Foreign countries typically impose less thorough
          regulations on brokers, dealers, stock exchanges, insiders and listed
          companies than does the U.S., and foreign securities markets may be
          less liquid and more volatile than domestic markets. Investment in
          foreign securities involves higher costs than investment in United
          States securities, including higher transaction and custody costs as
          well as the imposition of additional taxes by foreign governments. In
          addition, security trading practices abroad may offer less protection
          to investors such as the Fund. Settlement of transactions in some
          foreign markets may be delayed or may be less frequent than in the 
          U.S., which could affect the liquidity of the Fund's portfolio. Also,
          it may be more

          difficult to obtain and enforce legal judgments against foreign
          corporate issuers than against domestic issuers and it may be
          impossible to obtain and enforce judgments against foreign
          governmental issuers.
    
          Because foreign securities generally are denominated and pay dividends
          or interest in foreign currencies, and the Fund may hold various
          foreign currencies from time to time, the value of the net assets of
          the Fund as measured in U.S. dollars can be affected favorably or
          unfavorably by changes in exchange rates. Generally, currency exchange
          transactions will be conducted on a spot (i.e., cash) basis at the
          spot rate prevailing in the currency exchange market. The cost of
          currency exchange transactions will generally be the difference
          between the bid and offer spot rate of the currency being purchased or
          sold. In order to protect against uncertainty in the level of future
          foreign currency exchange rates, the Fund is authorized to enter into
          certain foreign currency futures and forward contracts. However, it is
          not obligated to do so and, depending on the availability and cost of
          these devices, the Fund may be unable to use foreign currency futures
          and forward contracts to protect against currency uncertainty. Please
          see the Statement of Additional Information for further information.
              
    
          The forward currency market for the purchase or sale of United States
          dollars in most countries is not highly developed, and in certain
          countries, there may be no such market. If a devaluation of a currency
          is generally anticipated, the Fund may not be able to contract to sell
          the currency at an exchange rate more advantageous than that which
          would prevail after the anticipated amount of devaluation. In the
          event the Fund holds securities denominated in a currency that suffers
          a devaluation, the Fund's net asset values will suffer corresponding
          reductions. In this regard, in December 1994, the Mexican government
          determined to allow the Mexican peso to trade freely against the U.S.
          dollar rather than within a controlled band, which resulted in a
          significant devaluation of the Mexican peso against the dollar.
          Further, in July 1997, the Thai and Philippine governments allowed the
          baht and peso, respectively, to trade freely against the United States
          dollar resulting in a sharp devaluation of both currencies. In 1998
          Russia did the same, causing a sharp devaluation of the ruble.

RISK CONSIDERATIONS
- -------------------



          Fixed income securities are subject to various risks.  The two primary
          (but not exclusive) risks affecting fixed income instruments are
          "credit risk" and "interest rate risk."  These risks can affect a
          security's price volatility to varying degrees, depending upon the
          nature of the instrument.  In addition, the depth and liquidity of the
          market for an individual or class of fixed income security can also
          affect its price and, hence, the market value of the Fund.
    
Fixed Income Securities      
- -----------------------

          "Credit risk" refers to the likelihood that an issuer will default in
          the payment of principal and/or interest on an instrument.  Financial
          strength and solvency of an issuer are the primary factors influencing
          credit risk.  In addition, lack of or inadequacy of collateral or
          credit enhancements for a fixed income security may affect its credit
          risk.  Credit risk of a security may change over its life, and
          securities which are rated by rating agencies are often reviewed and
          may be subject to downgrade.

          The Fund may invest in convertible securities rated below investment
          grade.  Debt securities that are rated below investment grade are
          considered to be speculative; they are also commonly known as "junk"
          bonds.  Generally, lower-rated debt securities provide a higher yield
          than higher rated debt securities of similar maturity but are subject
          to greater credit risk than higher rated securities of similar
          maturity.  Such securities are regarded as predominantly speculative
          with respect to the issuer's continuing ability to meet principal and
          interest 



                                       14

          payments. Because investment in lower quality securities involves
          greater investment risk, achievement of the Fund's investment
          objective will be more dependent on the Adviser's analysis than would
          be the case if the Fund were investing in higher quality bonds. In
          addition, lower quality securities may be more susceptible to real or
          perceived adverse economic and individual corporate developments than
          would investment grade bonds. Moreover, the secondary trading market
          for lower quality securities may be less liquid than the market for
          investment grade bonds. This potential lack of liquidity may make it
          more difficult for the Adviser to value accurately certain portfolio
          securities.

          "Interest rate risk" refers to the risks associated with market
          changes in interest rates.  Interest rate changes may affect the value
          of a fixed income security directly (especially in the case of fixed
          rate securities) and indirectly (especially in the case of adjustable
          rate securities).  In general, rises in interest rates will negatively
          impact the price of fixed rate securities and falling interest rates
          will have a positive effect on price.  The degree to which a
          security's price will change as a result of changes in interest rates
          is measured by its "duration."  For example, the price of a bond with
          a 5 year duration would be expected under normal market conditions to
          decrease 5% for every 1% increase in interest rates.  Generally,
          securities with longer maturities have a greater duration and thus are
          subject to greater price volatility from changes in interest rates.
          Adjustable rate instruments also react to interest rate changes in a
          similar manner although generally to a lesser degree (depending,
          however, on the characteristics of the reset terms, including the
          index chosen, frequency of reset and reset caps or floors, among other
          things).

Non-Diversified Status      
- ----------------------


          The Fund is non-diversified for 1940 Act purposes and as such may
          invest a larger percentage of its assets in individual issuers than a
          diversified investment company. In this regard, the Fund is not
          subject to the general limitation that it not invest more than 5% of
          its total assets in the securities of any one issuer. To the extent
          the Fund makes investments in excess of 5% of its assets in a
          particular issuer, its exposure to credit and market risks associated
          with that issuer is increased. However, the Fund's investments will be
          limited so as to qualify for the special tax treatment afforded
          "regulated investment companies" under the Internal Revenue Code of
          1986, as amended.

Year 2000      
- ---------
    
          The investment advisory and management services provided by the
          Adviser and the services provided to shareholders by the Transfer
          Agent depend on the smooth functioning of their computer systems.
          Many computer software systems in use today cannot recognize the year
          2000, but revert to 1900 or some other date, due to the manner in
          which dates were encoded and calculated.  Such a failure could have a
          negative impact on the handling of securities trades, pricing and
          account services.  The Adviser and the Transfer Agent have been
          actively working on necessary changes to their own computer systems to
          prepare for the year 2000 and expect that their systems will be
          adapted for year 2000 compliance before that date, but there can be no
          assurance that they will be successful, or that interaction with other
          non-complying computer systems will not impair their services at that
          time.  The Adviser has been, and is currently in contact with, each of
          its External Service Providers to evaluate their readiness for the
          year 2000.  The Adviser has requested each of its External Service
          Providers to either (i) prepare a description of its process for
          identifying date sensitive areas, its approach for implementing
          changes, and its testing methodology, along with its timetable for
          completion, or (ii) certified its year 2000 compliance.      

          In addition, it is possible that the markets for securities in which
          the Fund invests may be negatively affected by computer failures
          throughout the financial services industry commencing January 1, 2000.
          Improperly functioning trading systems may result in settlement
          problems.  Corporate and governmental data processing errors may
          result in production problems for individual companies and create
          overall economic uncertainties.  Earnings of individual 

       



                                       17

          issuers will be affected by remediation costs which may be
          substantial. Individual firms may further experience disruptions to
          their business due to the failure of their counterparts to address
          year 2000 problems, or could experience further disruption to the
          economy at large, which could adversely affect corporate earnings
          generally and the value of their securities. Accordingly, the Fund's
          portfolio investments may be negatively affected.

European Economic and Monetary Union      
- ------------------------------------
    
          The Fund may invest in European countries that have agreed to enter
          into the European Monetary Union (EMU). EMU is an effort by certain
          European countries to, among other things, reduce barriers between
          countries and eliminate fluctuations in their currencies. Among other
          things, EMU establishes a single European currency (the euro), which
          was introduced on January 1, 1999 and is expected to replace the
          existing national currencies of all initial EMU participants by July
          1, 2002. Upon introduction of the euro, certain securities (beginning
          with government and corporate bonds) have been redenominated in the
          euro and, thereafter will trade and make dividend and other payments
          only in euros.     
    
          Like other investment companies and business organizations, including
          the companies in which the Fund invests, the Fund could be adversely
          affected: (i) if the euro, or EMU as a whole does not take affect;
          (ii) if a participating country withdraws from EMU; or (iii) if the
          computing, accounting and trading systems used by the Fund's service
          providers, or by other business entities with which the Fund or its
          service providers do business, are not capable of recognizing the euro
          as a distinct currency at the time of, and following euro 
          conversion.

MANAGEMENT OF THE FUND
- ----------------------

          Investment Adviser

          The Fund's investment adviser is TCW Funds Management, Inc. (the
          "Adviser") and is headquartered at 865 South Figueroa Street, Suite
          1800, Los Angeles, California 90017. As of October 31, 1998, the
          Adviser and its affiliated companies, which provide a variety of
          trust, investment management and investment advisory services, had
          over $50 billion under management or committed for management.

          Advisory Agreement

          The Company and the Adviser have entered into an Investment Advisory
          and Management Agreement (the "Advisory Agreement"), under the terms
          of which the Company has employed the Adviser to manage the investment
          of its assets, to place orders for the purchase and sale of its
          portfolio securities,  and to be responsible for overall management of
          the Company's business affairs, subject to control by the Board of
          Directors of the Company.  The Adviser also pays certain costs of
          marketing the Fund, including sales personnel compensation, from
          legitimate profits from its investment advisory fees and other
          resources available to it. Under the Advisory Agreement, the Fund pays
          to the Adviser as compensation for the services rendered, facilities
          furnished, and expenses paid by it the following fees:

          The Advisory Agreement provides that the Adviser shall not be liable
          for any error of judgment or mistake of law or for any loss suffered
          by the Fund in connection with the matters to which the agreement
          relates, except a loss resulting from willful misfeasance, bad faith
          or gross negligence on the part of the Adviser in the performance of
          its duties or from reckless disregard by the Adviser of its duties
          under the agreement.

 .         MULTIPLE CLASS STRUCTURE        

          The Fund currently offers two classes of shares, Institutional Class
          shares and Class N shares.  Shares of each class of the Fund represent
          an equal pro rata interest in the Fund and generally gives you the
          same voting, dividend, liquidation, and other rights.  The
          Institutional Class shares are offered at the current net asset value.
          The Class N shares are also offered at the current net asset value,
          but will be subject to fees imposed under a distribution plan
          ("Distribution Plan") adopted pursuant to Rule 12b-1 under the
          Investment Company Act of 1940, as amended.  Pursuant to the
          Distribution Plan, the Fund compensates the Fund's distributor at a
          rate equal to 0.25% of the average daily net assets of the Fund
          attributable to its Class N shares for distribution and related
          services.  Because these fees are paid out of the Fund's Class N
          assets on an on-going basis, over time, these fees will increase the
          cost of your investment and may cost you more than paying other types
          of sales charges.

          Buying shares
    
          You pay no sales charges to invest in the Fund. Your price for Fund
          shares is the Fund's net asset value per share (NAV) which is
          calculated as of the close of trading on the New York Stock Exchange
          (usually 4:00 p.m. Eastern time) every day the exchange is open. Your
          order will be priced at the next NAV calculated after your order is
          accepted by the Fund. Orders received by the Fund's Transfer Agent
          from dealers, brokers or other service providers after the NAV for the
          day is determined, will receive that same day's NAV if the orders were
          received by the dealers, brokers or service providers from their
          customers prior to 4:00 p.m. and were transmitted to and received by
          the Transfer Agent prior to 8:00 a.m. Eastern time on the next day.
          The Fund's investments are valued based on market value, or where
          market quotations are not readily available, based on fair value as
          determined in good faith by the Fund pursuant to procedures
          established by the Fund's board.

          Selling shares

          You may sell shares at any time.  Your shares will be sold at the next
          NAV calculated after your order is accepted by the Fund's Transfer
          Agent.  Any certificates representing Fund shares being sold must be
          returned with your redemption request.  Your order will be processed
          promptly, and you will generally receive the proceeds within a week.

          Before selling recently purchased shares, please note that if the Fund
          has not yet collected payment for the shares you are selling, it may
          delay sending the proceeds for up to fifteen days.

          Written sell order

          Some circumstances require written sell orders, along with signature
          guarantees.  These include:

          .  amounts of $100,000 or more

          .  amounts of $1,000 or more on accounts whose address has been
             changed within the last 30 days

          .  requests to send the proceeds to a payee or address different than 
             what is on our records

          A signature guarantee helps protect against fraud.  You can obtain one
          from most banks or securities dealers but not from a notary public.
          Please call us to ensure that your signature guarantee will be
          processed correctly.

          Exchange privilege

          You can exchange from one Class N Galileo Fund into another.  You can
          request your exchange in writing or by phone.  Be sure to read the
          current prospectus for any Fund into which you are exchanging.  Any
          new account established through an exchange will have the same
          privileges as your original account (as long as they are available).

          Third Party Transactions

          You may buy and redeem Fund shares through certain broker-dealers and
          financial organizations and their authorized intermediaries.  If
          purchases and redemptions of Fund shares are arranged and settlement
          is made at an investor's election through a registered broker-dealer,
          other than the Fund's distributor, that broker-dealer may, at its
          discretion, charge a fee for that service.

          Account statements

          Every Galileo investor automatically receives regular account
          statements.  You will also be sent a yearly statement detailing the
          tax characteristics of any dividends and distributions you have
          received.

          General policies

          If your account falls below $1,000 as a result of redemptions and or
          exchanges for six months or more, the Fund may close your account and
          send you the proceeds upon 60 days' written notice.

          Unless you decline telephone privileges on your New Account Form, you
          may be responsible for any fraudulent telephone order as long as the
          Transfer Agent takes reasonable measures to verify the order.

     The Fund restricts excessive trading (usually defined as more than four
     exchanges out of the Fund within a calendar year).  You are limited to one
     exchange of shares in the Fund during any 15-day period except investors in
     401(k) and other group retirement accounts, investors who purchase shares
     through certain broker-dealers and asset allocation accounts managed by the
     Adviser or an affiliate.  The Fund reserves the right to:

     .  refuse any purchase or exchange request that could adversely affect the
        Fund or its operations, including those from any individual or group
        who, in the Fund's view, are likely to engage in excessive trading

     .  change or discontinue its exchange privilege, or temporarily suspend
        this privilege during unusual market conditions

     .  delay sending out redemption proceeds for up to seven days (generally
        applies only in cases of very large redemptions, excessive trading or
        during unusual market conditions)

LARGE REDEMPTION AMOUNTS
- ------------------------
The Fund also reserves the right to make a "redemption in kind" - payment in 
portfolio securities rather than cash - if the amount you are redeeming in any 
90-day period is large enough to affect Fund operations (for example, if it 
equals more than $250,000 or represents more than 1% of the Fund's assets).

 .         DISTRIBUTIONS AND TAXES

          The amount of dividends of net investment income and distributions of
          net realized long and short-term capital gains payable to shareholders
          will be determined separately for the Fund. Dividends from the net
          investment income of the Fund will be declared and paid annually.  The
          Fund will distribute any net realized long or short-term capital gains
          at least annually.  Your distributions will be reinvested in the Fund
          unless you instruct the Fund otherwise.  There are no fees or sales
          charges on reinvestments.

          In any fiscal year in which the Fund qualifies as a regulated
          investment company and distributes to shareholders all of its net
          investment income and net capital gains, the Fund is relieved of
          Federal income tax.

          Generally, all dividends and capital gains are taxable whether they
          are reinvested or received in cash - unless you are exempt from
          taxation or entitled to tax deferral.  Capital gains distributions may
          be taxable at different rates depending on the length of time the Fund
          has held the assets sold.  Early each year, you will be notified as to
          the amount and Federal tax status of all distributions paid during the
          prior year.  Distributions may also be subject to state or local
          taxes.  The tax treatment of redemptions from a retirement plan
          account may differ from redemptions from an ordinary shareholder
          account.  If you redeem shares of the Fund or exchange them for shares
          of another Fund, any gain on the transaction may be subject to tax.
          You must provide the Fund with a correct taxpayer identification
          number (generally your Social Security Number) and certify that you
          are not subject to backup withholding.  If you fail to do so, the IRS
          can require the Fund to withhold 31% of your taxable distributions and
          redemptions.  Federal law also requires the Fund to withhold 30% or
          the applicable tax treaty rate from dividends paid to nonresident
          alien, non-U.S. partnership and non-U.S. corporation shareholder
          accounts.

          This is a brief summary of some of the tax laws that affect your
          investment in the Fund.  Please see the Statement of Additional
          Information and your tax adviser for further information.

 .         FINANCIAL HIGHLIGHTS  


          The financial highlights table is intended to help you understand the
          Fund's financial performance for the fiscal years indicated.  Certain
          information reflects financial results for a single Fund share.
          "Total return" shows how much your investment in the Institutional
          Class shares of the Fund would have increased (or decreased) during
          each period, assuming you had reinvested all dividends and
          distributions (Class N shares of the Fund commenced operations on
          March 1, 1999).  These figures have been audited by Deloitte & Touche
          LLP, whose report, along with Company's financial statements, are
          included in the annual report, which is available upon request.

INVESTMENT OBJECTIVES AND PRINCIPAL STRATEGIES
- ----------------------------------------------

 
The Fund is affected by changes in the economy, or in securities and other
markets. There is also the possibility that investment decisions the Adviser
makes will not accomplish what they were designed to achieve or that companies
in which the Fund invests will have disappointing performance or not pay their
debts.

Under adverse market conditions, the Fund could invest some or all of its assets
in money market securities.  Although the Fund would do this only in seeking to
avoid losses, it could have the effect of reducing the benefit from any upswing
in the market.

PRINCIPAL RISKS
- ---------------
 
Risk is the chance that you will lose money on your investment or that it will
not earn as much as you expect. In general, the greater the risk, the more money
your investment can earn for you and the more you can lose. Since shares of the
Fund represent an investment of securities with fluctuating market prices, the
value of Fund shares will vary as the Fund's portfolio securities increase or
decrease. Therefore, the value of an investment in the Fund could go down as
well as up. All investments are subject to:
     
 .     MARKET RISK     
 
      There is the possibility that the returns from the types of securities in
      which the Fund invests will under perform returns from the various general
      securities markets or different asset classes. Different types of
      securities tend to go through cycles of outperformance and
      underperformance in comparison to the general securities markets.
 
 .     SECURITIES SELECTION RISK
 
      There is the possibility that the specific securities held in the Fund's
      portfolio will underperform other funds in the same asset class or
      benchmarks that are representative of the general performance of the asset
      class because of the portfolio manager's choice of securities.
 
 .     PRICE VOLATILITY
 
      There is the possibility that the value of the Fund's portfolio will
      change as the prices of its investments go up or down. Although stocks
      offer the potential for greater long-term growth than most fixed income
      securities, stocks generally have higher short-term volatility.
 
The Fund may also be subject to the following risks:
 
 .     LIQUIDITY RISK
 
      There is the possibility that the Fund may lose money or be prevented from
      earning capital gains if it cannot sell a security at the time and price
      that is most beneficial to the Fund. The Fund is subject to liquidity risk
      because it invests primarily in securities of small sized companies.
 
 .     FOREIGN INVESTING RISK
     
      There is the likelihood that foreign investments may be riskier than U.S.
      investments because of a lack of political stability, foreign controls on
      investment and currency exchange rates, fluctuation in currency exchange
      rates, withholding taxes, and lack of adequate company information. The
      Fund is subject to foreign investing risk because it may invest a portion
      of its assets in foreign company securities. In addition, because foreign
      securities generally are denominated and pay dividends or interest in
      foreign currencies, the Fund may hold various foreign currencies, the
      value of the net assets of the Fund as measured in U.S. dollars can be
      affected favorably or unfavorably by changes in exchange rates.    

                                       4
<PAGE>
 
PRINCIPAL RISKS
- ---------------

      Because the Fund is non-diversified for 1940 Act purposes, it may invest
      more than 5% of its total assets in the securities of any one issuer.
      Consequently, its exposure to credit and market risks associated with that
      issuer is increased.

      Your investment is not a bank deposit, and it is not insured or guaranteed
      by the Federal Deposit Insurance Corporation or any other government
      agency.

PERFORMANCE SUMMARY
- -------------------
     
The two tables below show the Fund's annual returns and its long-term
performance with respect to its Institutional Class shares (Class N shares of
the Fund commenced operations on March 1, 1999). The first table shows you how
the Fund's performance has varied from year to year. The second compares the
Fund's performance over time to that of a broad-based securities index. Both
tables assume reinvestment of dividends and distributions. The performance
information includes performance of the predecessor limited partnership, which
was managed by a predecessor of TCW Funds Management, Inc. using the same
investment strategy as the Fund. The performance of the partnership was
calculated using performance standards applicable to private investment
partnerships which take into account all elements of total return and reflect
the deduction of all fees and expenses of operation. The predecessor limited
partnership, was not registered under the Investment Company Act of 1940 ("1940
Act") and therefore, was not subject to certain investment restrictions imposed
by the 1940 Act and Subchapter M of the Internal Revenue Code of 1986, as
amended. If the limited partnership had been registered under the 1940 Act its
performance could have been adversely affected. As with all mutual funds, past
performance is not a prediction of future results.

FUND EXPENSES AND EXPENSE EXAMPLE
- ---------------------------------
 
As an investor, you pay certain fees and expenses in connection with the Fund,
which are described in the table below. Annual Fund operating expenses are paid
out of Fund assets, so their effect is included in the share price. The Class N
shares of the Fund have no sales charge (load), but are subject to Rule 12b-1
distribution fees.

Expense Example

This Example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other mutual funds.

This Example shows what you could pay in expenses over time. It uses the same
hypothetical conditions other funds use in their prospectuses: $10,000 Initial
Investment, 5% total return each year and no changes in expenses. The figures
shown would be the same whether or not you sold your shares at the end of a
period. Because actual return and expenses will be higher or lower, the example
is for comparison purposes only.

 . INVESTMENT OBJECTIVES/APPROACH
- --------------------------------
    
The Fund seeks long-term capital appreciation. To pursue this goal, it invests
(except when maintaining a temporary defensive position) at least 65% of the
value of its total assets in equity securities issued by companies with market
capitalizations, at the time of acquisition, within the capitalization range of
the companies comprising the Standard & Poor's Small Cap 600 Index.     

In managing the Fund's investments, the Adviser pursues a small cap growth
investment philosophy. That philosophy consists of fundamental company-by-
company analysis used in conjunction with technical and quantitative market
analysis to screen potential investments and to continuously monitor securities
in the Fund's portfolio.

Douglas S. Foreman, Christopher J. Ainley, Nicholas J. Capuano and
Charles Larsen are the Fund's portfolio managers.


Concepts to understand
- ----------------------
Small-Sized Companies seek long-term capital appreciation by focusing on small,
fast-growing companies that offer cutting-edge products, services or 
technologies. Because these companies are often in their early stages of 
development, their stocks tend to fluctuate more than most other securities.

                                       9
<PAGE>
 
 . MAIN RISKS
- ------------

The Fund holds primarily stocks, which may go up or down in value, sometimes
rapidly and unpredictably. Although stocks offer the potential for greater long-
term growth than most fixed income securities, stocks generally have higher
short-term volatility. In addition, the Fund may hold convertible debt
securities. Many convertible debt securities are rated below investment grade
and are considered speculative by rating agencies as to repayment of principal
and interest.

The primary risks affecting this Fund are "price volatility" and "liquidity
risk." Price volatility refers to the possibility that the value of the Fund's
portfolio will change as the prices of its investments go up or down. This Fund
may be subject to greater price volatility than funds that invest in the
securities of large or midcap companies. Liquidity risk refers to the
possibility that the Fund may lose money or be prevented from earning capital
gains if it cannot sell securities at the time and price that is most beneficial
to the Fund. Because the securities of small-size companies may be less liquid
than the securities of large-size companies, the Fund may be more susceptible to
liquidity risk than funds that invest in the securities of large-sized
companies.

The Fund may invest some assets in options. This practice is used primarily to
hedge the Fund's portfolio, but may be used to increase returns; however, such
practice sometimes may reduce returns or increase volatility.

The Fund seeks to earn additional income by making loans of its portfolio
securities to brokers, dealers and other financial institutions. The loans will
be secured at all times by cash and liquid high grade debt obligations. As with
any extension of credit, there are risks of delay in recovery and in some cases
even loss of rights in the collateral should the borrower fail financially.

    
The Fund may engage in active portfolio management which may result in increased
fund transaction expenses and have tax consequences such as increased realized 
gains for investors.

================================================================================
 . RISK CONSIDERATIONS
- ---------------------

Please consider the following risks before investing in the Fund.

Various market risks can affect the price or liquidity of an issuer's
securities. Adverse events occurring with respect to an issuer's performance or
financial position can depress the value of the issuer's securities. The
liquidity in a market for a particular security will affect its value and may be
affected by factors relating to the issuer, as well as the depth of the market
for that security. Other market risks that can affect value include a market's
current attitudes about types of securities, market reactions to political or
economic events, and tax and regulatory effects (including lack of adequate
regulations for a market or particular type of instrument). Market restrictions
on trading volume can also affect price and liquidity.

Prices of many securities tend to be more volatile in the short-term. Therefore
an investor who trades frequently or redeems in the short-term is more likely to
incur loss than an investor who holds investments for the longer term. The fewer
the number of issuers in which a Fund invests, the greater the potential
volatility of its portfolio.
    
The Adviser may temporarily invest up to 100% of the Fund's assets in high
quality, short-term money market instruments if it believes adverse economic or
market conditions, such as excessive volatility or sharp market declines,
justify taking a defensive investment posture. If the Fund attempts to limit
investment risk by temporarily taking a defensive investment position, it may be
unable to pursue its investment objective during that time and it may miss out
on some or all of an upswing in the securities markets.    

General Investment Risk
- -----------------------

Since shares of the Fund represent an investment in securities with fluctuating 
market prices, the value of Fund shares will vary as the value of the Fund's
portfolio securities increases or decreases. Therefore, the value of an 
investment in the Fund could go down as well as up.

                                       11
<PAGE>
 
 . RISK CONSIDERATIONS
- ---------------------

FOREIGN INVESTING
- -----------------

Investment in foreign securities involves special risks in addition to the usual
risks inherent in domestic investments. These include: political or economic
instability; the unpredictability of international trade patterns; the
possibility of foreign governmental actions such as expropriation,
nationalization or confiscatory taxation; the imposition or modification of
foreign currency or foreign investment controls; the imposition of withholding
taxes on dividends, interest and gains; price volatility; and fluctuations in
currency exchange rates.
    
As compared to United States companies, foreign issuers generally disclose less
financial and other information publicly and are subject to less stringent and
less uniform accounting, auditing and financial reporting standards. Foreign
countries typically impose less thorough regulations on brokers, dealers, stock
exchanges, insiders and listed companies than does the U.S., and foreign
securities markets may be less liquid and more volatile than domestic markets.
Investment in foreign securities involves higher costs than investment in United
States securities, including higher transaction and custody costs as well as the
imposition of additional taxes by foreign governments. In addition, security
trading practices abroad may offer less protection to investors such as the
Fund. Settlement of transactions in some foreign markets may be delayed or may
be less frequent than in the U.S., which could affect the liquidity of the
Fund's portfolio. Also, it may be more     

                                       12
<PAGE>
 
difficult to obtain and enforce legal judgments against foreign corporate
issuers than against domestic issuers and it may be impossible to obtain and
enforce judgments against foreign governmental issuers.
    
Because foreign securities generally are denominated and pay dividends or
interest in foreign currencies, and the Fund may hold various foreign currencies
from time to time, the value of the net assets of the Fund as measured in United
States dollars can be affected favorably or unfavorably by changes in exchange
rates. Generally, currency exchange transactions will be conducted on a spot
(i.e., cash) basis at the spot rate prevailing in the currency exchange market.
 ----
The cost of currency exchange transactions will generally be the difference
between the bid and offer spot rate of the currency being purchased or sold. In
order to protect against uncertainty in the level of future foreign currency
exchange rates, the Fund is authorized to enter into certain foreign currency
futures and forward contracts. However, it is not obligated to do so and,
depending on the availability and cost of these devices, the Fund may be unable
to use foreign currency futures and forward contracts to protect against
currency uncertainty. Please see the State of Additional Information for further
information.     
    
The forward currency market for the purchase or sale of U.S. dollars in most
countries is not highly developed, and in certain countries, there may be no
such market. If a devaluation of a currency is generally anticipated, the Fund
may not be able to contract to sell the currency at an exchange rate more
advantageous than that which would prevail after the anticipated amount of
devaluation. In the event the Fund holds securities denominated in a currency
that suffers a devaluation, the Fund's net asset values will suffer
corresponding reductions. In this regard, in December 1994, the Mexican
government determined to allow the Mexican peso to trade freely against the
United States dollar rather than within a controlled band, which action resulted
in a significant devaluation of the Mexican peso against the dollar. Further, in
July 1997, the Thai and Philippine governments allowed the baht and peso,
respectively, to trade freely against the U.S. dollar resulting in a sharp
devaluation of both currencies, and in 1998 Russia did the same, causing a sharp
devaluation of the ruble.

 . RISK CONSIDERATIONS
- ---------------------

Fixed Income Securities
- -----------------------

Fixed income securities are subject to various risks. The two primary (but not
exclusive) risks affecting fixed income instruments are "credit risk" and
"interest rate risk." These risks can affect a security's price volatility to
varying degrees, depending upon the nature of the instrument. In addition, the
depth and liquidity of the market for an individual or class of fixed income
security can also affect its price and, hence, the market value of the Fund.


"Credit risk" refers to the likelihood that an issuer will default in the
payment of principal and/or interest on an instrument. Financial strength and
solvency of an issuer are the primary factors influencing credit risk. In
addition, lack of or inadequacy of collateral or credit enhancements for a fixed
income security may affect its credit risk. Credit risk of a security may change
over its life, and securities which are rated by rating agencies are often
reviewed and may be subject to downgrade.

The Fund may invest in convertible securities rated below investment grade. Debt
securities that are rated below investment grade are considered to be
speculative; they are also commonly known as "junk" bonds. Generally, lower-
rated debt securities provide a higher yield than higher rated debt securities
of similar maturity but are subject to greater credit risk than higher rated
securities of similar maturity. Such securities are regarded as predominantly
speculative with respect to the issuer's continuing ability to meet principal
and interest 

                                       14
<PAGE>
 
payments. Because investment in lower quality securities involves greater
investment risk, achievement of the Fund's investment objective will be more
dependent on the Adviser's analysis than would be the case if the Fund were
investing in higher quality bonds. In addition, lower quality securities may be
more susceptible to real or perceived adverse economic and individual corporate
developments than would investment grade bonds. Moreover, the secondary trading
market for lower quality securities may be less liquid than the market for
investment grade bonds. This potential lack of liquidity may make it more
difficult for the Adviser to value accurately certain portfolio securities.

"Interest rate risk" refers to the risks associated with market changes in
interest rates. Interest rate changes may affect the value of a fixed income
security directly (especially in the case of fixed rate securities) and
indirectly (especially in the case of adjustable rate securities). In general,
rises in interest rates will negatively impact the price of fixed rate
securities and falling interest rates will have a positive effect on price. The
degree to which a security's price will change as a result of changes in
interest rates is measured by its "duration." For example, the price of a bond
with a 5 year duration would be expected under normal market conditions to
decrease 5% for every 1% increase in interest rates. Generally, securities with
longer maturities have a greater duration and thus are subject to greater price
volatility from changes in interest rates. Adjustable rate instruments also
react to interest rate changes in a similar manner although generally to a
lesser degree (depending, however, on the characteristics of the reset terms,
including the index chosen, frequency of reset and reset caps or floors, among
other things).

 . RISK CONSIDERATIONS
- ---------------------

Non-Diversified Status
- ----------------------

The Fund is non-diversified for 1940 Act purposes and as such may invest a
larger percentage of its assets in individual issuers than a diversified
investment company. In this regard, the Fund is not subject to the general
limitation that it not invest more than 5% of its total assets in the securities
of any one issuer. To the extent the Fund makes investments in excess of 5% of
its assets in a particular issuer, its exposure to credit and market risks
associated with that issuer is increased. However, the Fund's investments will
be limited so as to qualify for the special tax treatment afforded "regulated
investment companies" under the Internal Revenue Code of 1986, as amended.

                                       16
<PAGE>
 
 . RISK CONSIDERATIONS
- ---------------------

Year 2000
- ---------
    
The investment advisory and management services provided by the Adviser and the
services provided to shareholders by the Transfer Agent depend on the smooth
functioning of their computer systems. Many computer software systems in use
today cannot recognize the year 2000, but revert to 1900 or some other date, due
to the manner in which dates were encoded and calculated. Such a failure could
have a negative impact on the handling of securities trades, pricing and account
services. The Adviser and the Transfer Agent have been actively working on
necessary changes to their own computer systems to prepare for the year 2000 and
expect that their systems will be adapted for year 2000 compliance before that
date, but there can be no assurance that they will be successful, or that
interaction with other non-complying computer systems will not impair their
services at that time. The Adviser has been, and is currently in contact with,
each of its External Service Providers to evaluate their readiness for the year
2000. The Adviser has requested each of its External Service Providers to either
(i) prepare a description of its process for identifying date sensitive areas,
its approach for implementing damages, its testing methodology, along with its
timetable for completion, or (ii) certify its year 2000 compliance.     

In addition, it is possible that the markets for securities in which the Fund
invests may be negatively affected by computer failures throughout the financial
services industry commencing on January 1, 2000. Improperly functioning trading
systems may result in settlement problems. In addition, corporate and
governmental data processing errors may result in production problems for
individual companies and create overall economic uncertainties. Earnings of
individual 

                                       17
<PAGE>
 
issuers will be affected by remediation costs which may be substantial.
Individual firms may further experience disruptions to their business due to the
failure of their counterparts to address year 2000 problems, or could experience
further disruption to the economy at large, which could adversely affect
corporate earnings generally and the value of their securities. Accordingly, the
Fund's portfolio investments may be negatively affected.

 . RISK CONSIDERATIONS
- ---------------------

European Economic and Monetary Union
- ------------------------------------
    The Fund may invest in European countries that have agreed to enter into the
European Monetary Union (EMU). EMU is an effort by certain European countries
to, among other things, reduce barriers between countries and eliminate
fluctuations in their currencies. Among other things, EMU establishes a single
European currency (the euro), which was introduced on January 1, 1999 and is
expected to replace the existing national currencies of all initial EMU
participants by July 1, 2002. Upon introduction of the euro, certain securities
(beginning with government and corporate bonds) have been redonominated in the
euro and, thereafter trade and make dividend and other payments only in euros.
    
    
Like other investment companies and business organizations, including the
companies in which the Fund invests, the Fund could be adversely affected: (i)
if the euro, or EMU as a whole does not take effect; (ii) if a participating
country withdraws from EMU; or (iii) if the computing, accounting and trading
systems used by the Fund's service providers, or by other business entities with
which the Fund or its service providers do business, are not capable of
recognizing the euro as a distinct currency at the time of, and following euro
conversion.

Advisory Agreement

The Company and the Adviser have entered into an Investment Advisory and
Management Agreement (the "Advisory Agreement"), under the terms of which the
Company has employed the Adviser to manage the investment of its assets, to
place orders for the purchase and sale of its 

                                       20
<PAGE>
     
portfolio securities, and to be responsible for overall management of the
Company's business affairs, subject to control by the Board of Directors of the
Company. The Adviser also pays certain costs of marketing the Fund, including
sales personnel compensation, from legitimate profits from its investment
advisory fees and other resources available to it. Under the Advisory Agreement,
the Fund pays to the Adviser as compensation for the services rendered,
facilities furnished, and expenses paid by it the following fees:

Small Cap Growth                                  1.00%


The Advisory Agreement provides that the Adviser shall not be liable for any
error of judgment or mistake of law or for any loss suffered by the Fund in
connection with the matters to which the agreement relates, except a loss
resulting from willful misfeasance, bad faith or gross negligence on the part of
the Adviser in the performance of its duties or from reckless disregard by the
Adviser of its duties under the agreement.

 .MULTIPLE CLASS STRUCTURE
- -------------------------

The Fund currently offers two classes of shares, Institutional Class shares and
Class N shares. Shares of each class of the Fund represent an equal pro rata
interest in the Fund and generally gives you the same voting, dividend,
liquidation, and other rights. The Institutional Class shares are offered at the
current net asset value. The Class N shares are also offered at the current net
asset value, but will be subject fees imposed under a distribution plan
("Distribution Plan") adopted pursuant to Rule 12b-1 under the Investment
Company Act of 1940, as amended. Pursuant to the Distribution Plan, the Fund
compensates the Fund's distributor at a rate equal to 0.25% of the average daily
net assets of the Fund attributable to its Class N shares for distribution and
related services. Because these fees are paid out of the Fund's Class N assets
on an on-going basis, over time, these fees will increase the cost of your
investment and may cost you more than paying other types of sales charges.

 . ACCOUNT POLICIES AND SERVICES
- -------------------------------

Buying shares
    
You pay no sales charges to invest in the Fund. Your price for Fund shares is
the Fund's net asset value per share (NAV) which is calculated as of the close
of trading on the New York Stock Exchange (usually 4:00 p.m. Eastern time) every
day the exchange is open. Your order will be priced at the next NAV calculated
after your order is accepted by the Fund. Orders received by the Fund's Transfer
Agent from dealers, brokers or other service providers after the NAV for the day
is determined, will receive that same day's NAV if the orders were received by
the dealers, brokers or service providers from their customers prior to 4:00
p.m. and were transmitted to and received by the Transfer Agent prior to 8:00
a.m. Eastern time on the next day. The Fund's investments are valued based on
market value, or where market quotations are not readily available, based on
fair value as determined in good faith by the Fund pursuant to procedures
established by the Fund's board.

The TCW Galileo Funds, Inc. may waive the minimum initial investment. All
investments must be in U.S. dollars. Third-party checks, except those payable to
an existing shareholder, will normally not be accepted. If your check or wire
does not clear, you will be responsible for any loss the Fund incurs.     
    
Automatic Investment Plan ($100 Minimum)

Selling shares

You may sell shares at any time. Your shares will be sold at the next NAV
calculated after your order is accepted by the Fund's Transfer Agent. Any
certificates representing Fund shares being sold must be returned with your
redemption request. Your order will be processed promptly, and you will
generally receive the proceeds within a week.

Before selling recently purchased shares, please note that if the Fund has not
yet collected payment for the shares you are selling, it may delay sending the
proceeds for up to fifteen days.

Written sell order

Some circumstances require written sell orders, along with signature guarantees.
These include:

 .  amounts of $100,000 or more

 .  amounts of $1,000 or more on accounts whose address has been changed within
   the last 30 days

 .  requests to send the proceeds to a payee or address different than what is on
   our records

A signature guarantee helps protect against fraud. You can obtain one from most
banks or securities dealers but not from a notary public. Please call us to
ensure that your signature guarantee will be processed correctly.

Exchange privilege

You can exchange from one Class N Galileo Fund into another. You can request
your exchange in writing or by phone. Be sure to read the current prospectus for
any Fund into which you are exchanging. Any new account established through an
exchange will have the same privileges as your original account (as long as they
are available).

Third Party Transactions

You may buy and redeem Fund shares through certain broker-dealers and financial
organizations and their authorized.intermediaries. If purchases and redemptions
of Fund shares are arranged and settlement is made at an investor's election
through a registered broker-dealer, other than the Fund's distributor, that
broker-dealer may, at its discretion, charge a fee for that service.

                                       23
<PAGE>

LARGE REDEMPTION AMOUNTS
- ------------------------

The Fund also reserves the right to make a "redemption in kind" - payment in 
portfolio securities rather than cash - if the amount you are redeeming in any 
90-day period is large enough to affect Fund operations (for example, if it 
equals more than $250,000 or represents more than 1% of the Fund's assets). 

Account statements

Every Galileo investor automatically receives regular account statements. You
will also be sent a yearly statement detailing the tax characteristics of any
dividends and distributions you have received.

General policies

If your account falls below $1,000 as a result of redemptions and or exchanges
for six months or more, the Fund may close your account and send you the
proceeds upon 60 days' written notice.

Unless you decline telephone privileges on your New Account Form, you may be
responsible for any fraudulent telephone order as long as the Transfer Agent
takes reasonable measures to verify the order.

The Fund restricts excessive trading (usually defined as more than four
exchanges out of the Fund within a calendar year). You are limited to one
exchange of shares in the Fund during any 15-day period except investors in
401(k) and other group retirement accounts, investors who purchase shares
through certain broker-dealers and asset allocation accounts managed by the
Adviser or an affiliate. The Fund reserves the right to:

 .  refuse any purchase or exchange request that could adversely affect the Fund
   or its operations, including those from any individual or group who, in the
   Fund's view, are likely to engage in excessive trading

 .  change or discontinue its exchange privilege, or temporarily suspend this
   privilege during unusual market conditions

 .  delay sending out redemption proceeds for up to seven days (generally applies
   only in cases of very large redemptions, excessive

 . DISTRIBUTIONS AND TAXES
- -------------------------

The amount of dividends of net investment income and distributions of net
realized long and short-term capital gains payable to shareholders will be
determined separately for the Fund. Dividends from the net investment income of
the Fund will be declared and paid annually. The Fund will distribute any net
realized long or short-term capital gains at least annually. Your distributions
will be reinvested in the Fund unless you instruct the Fund otherwise. There are
no fees or sales charges on reinvestments.

In any fiscal year in which the Fund qualifies as a regulated investment company
and distributes to shareholders all of its net investment income and net capital
gains, the Fund is relieved of Federal income tax.

Generally, all dividends and capital gains are taxable whether they are
reinvested or received in cash - unless you are exempt from taxation or entitled
to tax deferral. Capital gains distributions may be taxable at different rates
depending on the length of time the Fund has held the assets sold. Early each
year, you will be notified as to the amount and Federal tax status of all
distributions paid during the prior year. Distributions may also be subject to
state or local taxes. The tax treatment of redemptions from a retirement plan
account may differ from redemptions from an ordinary shareholder account. If you
redeem shares of the Fund or exchange them for shares of another Fund, any gain
on the transaction may be subject to tax. You must provide the Fund with a
correct taxpayer identification number (generally your Social Security Number)
and certify that you are not subject to backup withholding. If you fail to do
so, the IRS can require the Fund to withhold 31% of your taxable distributions
and redemptions. Federal law also requires the Fund to withhold 30% or the
applicable tax treaty rate from dividends paid to nonresident alien, non-U.S.
partnership and non-U.S. corporation shareholder accounts.

This is a brief summary of some of the tax laws that affect your investment in
the Fund. Please see the Statement of Additional Information and your tax
adviser for further information.

 . FINANCIAL HIGHLIGHTS
- ----------------------

The financial highlights table is intended to help you understand the Fund's
financial performance for the fiscal years indicated. Certain information
reflects financial results for a single Fund share. "Total return" shows how
much your investment in the Institutional Class shares of the Fund would have
increased (or decreased) during each period, assuming you had reinvested all
dividends and distributions (Class N shares commenced operations on March 1,
1999). These figures have been audited by Deloitte & Touche LLP, whose report,
along with Company's financial statements, are included in the annual report,
which is available upon request.

/3/  The Adviser has voluntarily agreed to reduce its fee from the Fund, or to
     pay the operating expenses of the Fund, to the extent necessary to limit
     the ordinary operating expenses of the Fund to 1.09% of net assets through
     December 31, 1994. Had such action not been taken, total annualized
     operating expenses for the period March 1, 1994 (commencement of
     operations) through October 31, 1994 would have been 1.39% of average net
     assets and for the fiscal year ended October 31, 1995, total operating
     expenses would have been 1.24% of average net assets.

INVESTMENT OBJECTIVES AND PRINCIPAL STRATEGIES
- --------------------------------------------------------------------------------

 
 
The Fund is affected by changes in the economy, or in securities and other
markets. There is also the possibility that investment decisions the Adviser
makes will not accomplish what they were designed to achieve or that companies
in which the Fund invests will have disappointing performance or not pay their
debts.

Under adverse market conditions, the Fund could invest some or all of its assets
in money market securities.  Although the Fund would do this only in seeking to
avoid losses, it could have the effect of reducing the benefit from any upswing
in the market.

PRINCIPAL RISKS
- --------------------------------------------------------------------------------
 
Risk is the chance that you will lose money on your investment or that it will
not earn as much as you expect. In general, the greater the risk, the more money
your investment can earn for you and the more you can lose. Since shares of the
Fund represent an investment of securities with fluctuating market prices, the
value of Fund shares will vary as the Fund's portfolio securities increase or
decrease. Therefore, the value of an investment in the Fund could go down as
well as up. All investments are subject to:
     
 .     MARKET RISK     
 
      There is the possibility that the returns from the types of securities in
      which the Fund invests will underperform returns from the various general
      securities markets or different asset classes. Different types of
      securities tend to go through cycles of outperformance and
      underperformance in comparison to the general securities markets.
 
 .     SECURITIES SELECTION RISK
 
      There is the possibility that the specific securities held in the Fund's
      portfolio will underperform other funds in the same asset class or
      benchmarks that are representative of the general performance of the asset
      class because of the portfolio manager's choice of securities.
 
 .     PRICE VOLATILITY
 
      There is the possibility that the value of the Fund's portfolio will
      change as the prices of its investments go up or down. Although stocks
      offer the potential for greater long-term growth than most fixed income
      securities, stocks generally have higher short-term volatility.
 
The Fund may also be subject (in varying degrees) to the following risks:
 
 .     LIQUIDITY RISK
 
      There is the possibility that the Fund may lose money or be prevented from
      earning capital gains if it cannot sell a security at the time and price
      that is most beneficial to the Fund.
 
 .     FOREIGN INVESTING RISK
     
      There is the likelihood that foreign investments may be riskier than U.S.
      investments because of a lack of political stability, foreign controls on
      investment and currency exchange rates fluctuations in currency exchange
      rates, withholding taxes, and lack of adequate company information. The
      Fund is subject to foreign investing risk because it may invest a portion
      of its assets in foreign company securities. In addition, because foreign
      securities generally are denominated and pay dividends or interest in
      foreign currencies, and the Fund may hold various foreign currencies, the
      value of the net assets of the Fund as measured in U.S. dollars can be
      affected favorably or unfavorably by changes in exchange rates.    

                                       4
<PAGE>
 
- --------------------------------------------------------------------------------
PRINCIPAL RISKS
- --------------------------------------------------------------------------------
    
Because the Fund is non-diversified for purposes of the Investment Company Act
of 1940, as amended (the "1940 Act") it may invest more than 5% of its total
assets in the securities of any one issuer. Consequently, its exposure to credit
and market risks associated with that issuer is increased.     

Your investment is not a bank deposit, and it is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE SUMMARY
- --------------------------------------------------------------------------------
     
The two tables below show the Fund's annual returns and its long-term
performance with respect to its Institutional Class shares (Class N shares of
the Fund commenced operations on March 1, 1999). The first table shows you how
the Fund's performance has varied from year to year. The second compares the
Fund's performance over time to that of a broad-based securities index. Both
tables assume reinvestment of dividends and distributions. The performance
information includes performance of the predecessor limited partnership, which
was managed by a predecessor of TCW Funds Management, Inc. using the same
investment strategy as the Fund. The performance of the partnership was
calculated using performance standards applicable to private investment
partnerships which take into account all elements of total return and reflect
the deduction of all fees and expenses of operation. The predecessor limited
partnership, was not registered under the Investment Company Act of 1940 ("1940
Act") and therefore, was not subject to certain investment restrictions imposed
by the 1940 Act and Subchapter M of the Internal Revenue Code of 1986, as
amended. If the limited partnership had been registered under the 1940 Act its
performance could have been adversely affected. As with all mutual funds, past
performance is not a prediction of future results.

Expense Example

This Example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other mutual funds.

This Example shows what you could pay in expenses over time. It uses the same
hypothetical conditions other funds use in their prospectuses: $10,000 Initial
Investment, 5% total return each year and no changes in expenses. The figures
shown would be the same whether or not you sold your shares at the end of a
period. Because actual return and expenses will be higher or lower, the example
is for comparison purposes only.

LOGO      INVESTMENT OBJECTIVES/APPROACH
- ---------------------------------------

Concepts to understand
- ----------------------

Large capitalization companies are established companies that are considered
known quantities. Large companies often have the resources to weather economic
shifts, though they can be slower to innovate than small companies.

          The Fund seeks long-term capital appreciation.  Performance should be
          measured over a full market cycle.
    
          To pursue this goal, the Fund invests primarily in the common stocks
          of larger companies.  The investment philosophy underlying our
          strategy is a highly focused approach which seeks to achieve superior
          long-term returns by owning shares in companies that are believed to
          have strong and enduring business models and inherent advantages over
          their competitors.  Except when maintaining a temporary defensive
          position, the Fund anticipates that at least 65% of the value of its
          total assets will be invested in equity securities of these companies.
          In implementing its investment policy, the Fund may purchase and sell
          convertible securities and foreign securities.     

          Glen A. Bickerstaff is the Fund's portfolio manager.

<PAGE>
 
LOGO      MAIN RISKS
- --------------------

          The Fund holds primarily stocks, which may go up or down in value,
          sometimes rapidly and unpredictably.  Although stocks offer the
          potential for greater long-term growth than most fixed income
          securities, stocks generally have higher short-term volatility.  In
          addition, the Fund may hold convertible debt securities.  Many
          convertible debt securities are rated below investment grade and are
          considered speculative by rating agencies as to repayment of principal
          and interest.

          The primary risks affecting this Fund are "price volatility" and
          "foreign investing risk."  Price volatility refers to the possibility
          that the value of the Fund's portfolio will change as the prices of
          its investments go up or down.  Although the Fund is subject to price
          volatility because of its stock investments, it is subject to less
          price volatility than funds that invest in the securities of smaller
          companies.  Because the Fund may invest a portion of its assets in
          securities issued by foreign companies, it may be subject to foreign
          investing risks.  Foreign investing risk refers to the likelihood that
          foreign investments may be riskier than U.S. investments because of
          many factors, some of which include:

          .  a lack of political or economic stability

          .  foreign controls on investment and currency exchange rates

          .  withholding taxes

          .  a lack of adequate company information
    
          In addition, securities traded only through foreign markets may be
          more volatile and are often harder to sell.  Volatility is a way to
          measure the changes in the price of a single security or an entire
          portfolio.  Large and frequent price changes indicate higher
          volatility, which generally indicates that there is a greater chance
          you could lose money over the short-term.  The Fund is also subject to
          foreign currency risk. Because foreign securities are generally
          denominated and pay dividends or interest in foreign currencies, the
          value of the net assets of the Fund as measured in U.S. dollars
          will be affected favorably or unfavorably by changes in exchange
          rates.    

          The Fund may invest some assets in options, futures and foreign
          currency futures, and forward contracts.  These practices are used
          primarily to hedge the Fund's portfolio but may be used to increase
          returns; however, such practices sometimes may reduce returns or
          increase volatility.

                                       10
<PAGE>
 
          The Fund seeks to earn additional income by making loans of its
          portfolio securities to brokers, dealers and other financial
          institutions.  The loans will be secured at all times by cash and
          liquid high grade debt obligations.  As with any extension of credit,
          there are risks of delay in recovery and in some cases even loss of
          rights in the collateral should the borrower fail financially.
    
          The Fund may engage in active portfolio management which may result in
          increased fund transaction expenses and have tax consequences such as
          increased realized gain for investors.

LOGO      RISK CONSIDERATIONS
- -----------------------------

General Investment Risk
- -----------------------

Since shares of the Fund represent an investment in securities with fluctuating 
market prices, the value of Fund shares will vary as the value of the Fund's 
portfolio securities increases or decreases. Therefore, the value of an 
investment in the Fund could go down as well as up.

          Please consider the following risks before investing in the Fund.

          Various market risks can affect the price or liquidity of an issuer's
          securities.  Adverse events occurring with respect to an issuer's
          performance or financial position can depress the value of the
          issuer's securities.  The liquidity in a market for a particular
          security will affect its value and may be affected by factors relating
          to the issuer, as well as the depth of the market for that security.
          Other market risks that can affect value include a market's current
          attitudes about types of securities, market reactions to political or
          economic events, and tax and regulatory effects (including lack of
          adequate regulations for a market or particular type of instrument).
          Market restrictions on trading volume can also affect price and
          liquidity.

          Prices of many securities tend to be more volatile in the short-term.
          Therefore, an investor who trades frequently or redeems in the short-
          term is more likely to incur loss than an investor who holds
          investments for the longer term.  The fewer the number of issuers in
          which a Fund invests, the greater the potential volatility of its
          portfolio.
    
          The Adviser may temporarily invest up to 100% of the Fund's assets in
          high quality, short-term money market instruments if it believes
          adverse economic or market conditions, such as excessive volatility or
          sharp market declines, justify taking a defensive investment posture.
          If the Fund attempts to limit investment risk by temporarily taking a
          defensive investment position, it may be unable to pursue its
          investment objective during that time, and it may miss out on some or
          all of an upswing in the securities markets.

- -----------------------------

Foreign Securities
- ------------------

          Investment in foreign securities involves special risks in addition to
          the usual risks inherent in domestic investments.  These include:
          political or economic instability; the unpredictability of
          international trade patterns; the possibility of foreign governmental
          actions such as expropriation, nationalization or confiscatory
          taxation; the imposition or modification of foreign currency or
          foreign investment controls; the imposition of withholding taxes on
          dividends, interest and gains; price volatility; and fluctuations in
          currency exchange rates.
    
          As compared to U.S. companies, foreign issuers generally disclose less
          financial and other information publicly and are subject to less
          stringent and less uniform accounting, auditing and financial
          reporting standards. Foreign countries typically impose less thorough
          regulations on brokers, dealers, stock exchanges, insiders and listed
          companies than does the United States, and foreign securities markets
          may be less liquid and more volatile than domestic markets. Investment
          in foreign securities involves higher costs than investment in U.S.
          securities, including higher transaction and custody costs as well as
          the imposition of additional taxes by foreign governments. In
          addition, security trading practices abroad may offer less protection
          to investors such as the Fund. Settlement of transactions in some
          foreign markets may be delayed or may be less frequent than in the
          U.S., which could affect the liquidity of the Fund's portfolio. Also,
          it may be more difficult to obtain and enforce legal judgments against
          foreign     
                                       13

          corporate issuers than against domestic issuers and it may be
          impossible to obtain and enforce judgments against foreign
          governmental issuers.
    
          Because foreign securities generally are denominated and pay dividends
          or interest in foreign currencies, and the Fund may hold various
          foreign currencies from time to time, the value of the net assets of
          the Fund as measured in U.S. dollars can be affected favorably or
          unfavorably by changes in exchange rates. Generally, currency exchange
          transactions will be conducted on a spot (i.e., cash) basis at the
          spot rate prevailing in the currency exchange market. The cost of
          currency exchange transactions will generally be the difference
          between the bid and offer spot rate of the currency being purchased or
          sold. In order to protect against uncertainty in the level of future
          foreign currency exchange rates, the Fund is authorized to enter into
          certain foreign currency futures and forward contracts. However, it is
          not obligated to do so and, depending on the availability and cost of
          these devices, the Fund may be unable to use foreign currency futures
          and forward contracts to protect against currency uncertainty. Please
          see the Statement of Additional Information for further
          information.    

          The forward currency market for the purchase or sale of U.S. dollars
          in most countries is not highly developed, and in certain countries,
          there may be no such market.  If a devaluation of a currency is
          generally anticipated, the Fund may not be able to contract to sell
          the currency at an exchange rate more advantageous than that which
          would prevail after the anticipated amount of devaluation.  In the
          event the Fund holds securities denominated in a currency that suffers
          a devaluation, the Fund's net asset values will suffer corresponding
          reductions.  In this regard, in December 1994, the Mexican government
          determined to allow the Mexican peso to trade freely against the U.S.
          dollar rather than within a controlled band, which action resulted in
          a significant devaluation of the Mexican peso against the dollar.
          Further, in July 1997, the Thai and Philippine governments allowed the
          baht and peso, respectively, to trade freely against the U.S. dollar
          resulting in a sharp devaluation of both currencies, and in 1998
          Russia did the same, causing a sharp devaluation of the ruble.

Fixed Income Securities
- -----------------------

          Fixed income securities are subject to various risks.  The two primary
          (but not exclusive) risks affecting fixed income instruments are
          "credit risk" and "interest rate risk."  These risks can affect a
          security's price volatility to varying degrees, depending upon the
          nature of the instrument.  In addition, the depth and liquidity of the
          market for an individual or class of fixed income security can also
          affect its price and, hence, the market value of the Fund.

          "Credit risk" refers to the likelihood that an issuer will default in
          the payment of principal and/or interest on an instrument.  Financial
          strength and solvency of an issuer are the primary factors influencing
          credit risk.  In addition, lack of or inadequacy of collateral or
          credit enhancements for a fixed income security may affect its credit
          risk.  Credit risk of a security may change over its life, and
          securities which are rated by rating agencies are often reviewed and
          may be subject to downgrade.

          The Fund may invest in convertible securities rated below investment
          grade.  Debt securities that are rated below investment grade are
          considered to be speculative; they are also commonly known as "junk"
          bonds.  Generally, lower-rated debt securities provide a higher yield
          than higher rated debt securities of similar maturity but are subject
          to greater credit risk than higher rated securities of similar
          maturity.  Such securities are regarded as predominantly speculative
          with respect to the issuer's continuing ability to meet principal and
          interest payments.  Because investment in lower quality securities
          involves 

                                       15
<PAGE>
 
          greater investment risk, achievement of the Fund's investment
          objective will be more dependent on the Adviser's analysis than would
          be the case if the Fund were investing in higher quality bonds. In
          addition, lower quality securities may be more susceptible to real or
          perceived adverse economic and individual corporate developments than
          would investment grade bonds. Moreover, the secondary trading market
          for lower quality securities may be less liquid than the market for
          investment grade bonds. This potential lack of liquidity may make it
          more difficult for the Adviser to value accurately certain portfolio
          securities.

          "Interest rate risk" refers to the risks associated with market
          changes in interest rates.  Interest rate changes may affect the value
          of a fixed income security directly (especially in the case of fixed
          rate securities) and indirectly (especially in the case of adjustable
          rate securities).  In general, rises in interest rates will negatively
          impact the price of fixed rate securities and falling interest rates
          will have a positive effect on price.  The degree to which a
          security's price will change as a result of changes in interest rates
          is measured by its "duration."  For example, the price of a bond with
          a 5 year duration would be expected under normal market conditions to
          decrease 5% for every 1% increase in interest rates.  Generally,
          securities with longer maturities have a greater duration and thus are
          subject to greater price volatility from changes in interest rates.
          Adjustable rate instruments also react to interest rate changes in a
          similar manner although generally to a lesser degree (depending,
          however, on the characteristics of the reset terms, including the
          index chosen, frequency of reset and reset caps or floors, among other
          things).

Non-Diversified Status
- ----------------------

          The Fund is non-diversified for 1940 Act purposes and as such may
          invest a larger percentage of its assets in individual issuers than a
          diversified investment company. In this regard, the Fund is not
          subject to the general limitation that it not invest more than 5% of
          its total assets in the securities of any one issuer. To the extent
          the Fund makes investments in excess of 5% of its assets in a
          particular issuer, its exposure to credit and market risks associated
          with that issuer is increased. However, the Fund's investments will be
          limited so as to qualify for the special tax treatment afforded
          "regulated investment companies" under the Internal Revenue Code of
          1986, as amended.

Year 2000
- ---------
    
          The investment advisory and management services provided by the
          Adviser and the services provided to shareholders by the Transfer
          Agent depend on the smooth functioning of their computer systems.
          Many computer software systems in use today cannot recognize the year
          2000, but revert to 1900 or some other date, due to the manner in
          which dates were encoded and calculated.  That failure could have a
          negative impact on the handling of securities trades, pricing and
          account services.  The Adviser and the Transfer Agent have been
          actively working on necessary changes to their own computer systems to
          prepare for the year 2000 and expect that their systems will be
          adapted for year 2000 compliance before that date, but there can be no
          assurance that they will be successful, or that interaction with other
          non-complying computer systems will not impair their services at that
          time.  The Adviser has been, and is currently in contact with each of
          its External Service Providers to evaluate their readiness for the
          year 2000.  The Adviser has requested each of its External Service
          Providers to either (i) prepare a description of its process for
          identifying date sensitive areas, its approach for implementing
          changes, its testing methodology, along with its timetable for
          completion, or (ii) certify as to its year 2000 compliance.     

          In addition, it is possible that the markets for securities in which
          the Fund invests may be negatively affected by computer failures
          throughout the financial services industry commencing January 1, 2000.
          Improperly functioning trading systems may result in settlement
          problems.  In addition, corporate and governmental data processing
          errors may result in production problems for individual companies and
          create overall economic uncertainties.  Earnings of individual issuers
          will be affected by remediation costs which may be substantial.

          Individual firms may further experience disruptions to their business
          due to the failure of their counterparts to address year 2000
          problems, or could experience further disruption to the economy at
          large, which could adversely affect corporate earnings generally and
          the value of their securities.  Accordingly, the Fund's portfolio
          investments may be negatively affected.

European Economic and Monetary Union
- ------------------------------------
    
          The Fund may invest in European countries that have agreed to enter
          into the European Monetary Union (EMU).  EMU is an effort by certain
          European countries to, among other things, reduce barriers between
          countries and eliminate fluctuations in their currencies.  Among other
          things, EMU establishes a single European currency (the euro), which
          was introduced on January 1, 1999 and is expected to replace the
          existing national currencies of all initial EMU participants by July
          1, 2002.  Upon introduction of the euro, certain securities (beginning
          with government and corporate bonds) have been redenominated in the
          euro and, thereafter trade and make dividend and other payments only
          in euros.     
    
          Like other investment companies and business organizations, including
          the companies in which the Fund invests, the Fund could be adversely
          affected: (i) if the euro, or EMU as a whole does not take affect (ii)
          if a participating country withdraws from EMU; or (iii) if the
          computing, accounting and trading systems used by the Fund's service
          providers, or by other business entities with which the Fund or its
          service providers do business, are not capable of recognizing the euro

          Advisory Agreement

          The Company and the Adviser have entered into an Investment Advisory
          and Management Agreement (the "Advisory Agreement"), under the terms
          of which the Company has employed the Adviser to manage the investment
          of its assets, to place orders for the purchase and sale of its
          portfolio securities, and to be responsible for overall management of
          the Company's business affairs, subject to control by the Board of
          Directors of the Company.  The Adviser also pays certain costs of
          marketing the Fund, including sales personnel compensation, from
          legitimate profits from its investment advisory fees and other
          resources available to it.  Under the Advisory Agreement, the Fund
          pays to the Adviser as compensation for the services rendered,
          facilities furnished, and expenses paid by it the following fees:

</TABLE>

          The Advisory Agreement provides that the Adviser shall not be liable
          for any error of judgment or mistake of law or for any loss suffered
          by the Fund in connection with the matters to which the agreement
          relates, except a loss resulting from willful misfeasance, bad faith
          or gross negligence on the part of the Adviser in the performance of
          its duties or from reckless disregard by the Adviser of its duties
          under the agreement.


LOGO      MULTIPLE CLASS STRUCTURE
- ----------------------------------
    
          The Fund currently offers two classes of shares, Institutional Class
          shares and Class N shares.  Shares of each class of the Fund
          represents an equal pro rata interest in the Fund and generally gives
          you the same voting, dividend, liquidation, and other rights.  The
          Institutional Class shares are offered at the current net asset value.
          The Class N shares are also offered at the current net asset value,
          but will be subject to fees imposed under a distribution plan
          ("Distribution Plan") adopted pursuant to Rule 12b-1 under the 1940
          Act. Pursuant to the Distribution Plan, the Fund compensates the its
          distributor at a rate equal to 0.25% of the average daily net assets
          of the Fund attributable to its Class N shares for distribution and
          related services. Because these fees are paid out of the Fund's Class
          N assets on an on-going basis, over time, these fees will increase the
          cost of your investment and may cost you more than paying other types
          of sales charges.

- ---------------------------------------

          Buying shares

          You pay no sales charges to invest in the Fund. Your price for Fund
          shares is the Fund's net asset value per share (NAV) which is
          calculated as of the close of trading on the New York Stock Exchange
          (usually 4:00 p.m. Eastern time) every day the exchange is open. Your
          order will be priced at the next NAV calculated after your order is
          accepted by the Fund. Orders received by the Fund's Transfer Agent
          from dealers, brokers or other service providers after the NAV for the
          day is determined, will receive that same day's NAV if the orders were
          received by the dealers, brokers or service providers from their
          customers prior to 4:00 p.m. and were transmitted to and received by
          the Transfer Agent prior to 8:00 a.m. Eastern time on the next day.
          The Fund's investments are valued based on market value, or where
          market quotations are not readily available, based on fair value as
          determined in good faith by the Fund pursuant to procedures
          established by the Fund's board.

          Selling shares

          You may sell shares at any time.  Your shares will be sold at the next
          NAV calculated after your order is accepted by the Fund's Transfer
          Agent.  Any certificates representing Fund shares being sold must be
          returned with your redemption request.  Your order will be processed
          promptly, and you will generally receive the proceeds within a week.

          Before selling recently purchased shares, please note that if the Fund
          has not yet collected payment for the shares you are selling, it may
          delay sending the proceeds for up to fifteen days.

          Written sell order

          Some circumstances require written sell orders, along with signature
          guarantees.  These include:

          .  amounts of $100,00 or more

          .  amounts of $1,000 or more on accounts whose address has been
             changed within the last 30 days

          .  requests to send the proceeds to a payee or address different than
             what is on our records

          A signature guarantee helps protect against fraud.  You can obtain one
          from most banks or securities dealers but not from a notary public.
          Please call us to ensure that your signature guarantee will be
          processed correctly.

          Exchange privilege

          You can exchange from one Class N Galileo Fund into another.  You can
          request your exchange in writing or by phone.  Be sure to read the
          current prospectus for any Fund into which you are exchanging.  Any
          new account established through an exchange will have the same
          privileges as your original account (as long as they are available).

          Third Party Transactions

          You may buy and redeem Fund shares through certain broker-dealers and
          financial organizations and their authorized intermediaries.  If
          purchases and redemptions of Fund shares are arranged and settlement
          is made at an investor's election through a registered broker-dealer,
          other than the Fund's distributor, that broker-dealer may, at its
          discretion, charge a fee for that service.

          Account statements

          Every Galileo investor automatically receives regular account
          statements.  You will also be sent a yearly statement detailing the
          tax characteristics of any dividends and distributions you have
          received.

          General policies

          If your account falls below $1,000 as a result of redemptions and or
          exchanges for six months or more, the Fund may close your account and
          send you the proceeds upon 60 days' written notice.

          Unless you decline telephone privileges on your New Account Form, you
          may be responsible for any fraudulent telephone order as long as the
          Transfer Agent takes reasonable measures to verify the order.


LARGE REDEMPTION AMOUNTS
- ------------------------

The Fund also reserves the right to make a "redemption in kind" -- payment in 
portfolio securities rather than cash -- if the amount you are redeeming in any 
90-day period is large enough to affect Fund operations (for example, if it
equals more than $250,000 or represents more than 1% of the Fund's assets).

     The Fund restricts excessive trading (usually defined as more than four
     exchanges out of the Fund within a calendar year).  You are limited to one
     exchange of shares in the Fund during any 15-day period except investors in
     401(k) and other group retirement accounts, investors who purchase shares
     through certain broker-dealers and asset allocation accounts managed by the
     Adviser or an affiliate.  The Fund reserves the right to:

 .    refuse any purchase or exchange request that could adversely affect the
     Fund or its operations, including those from any individual or group who,
     in the Fund's view, are likely to engage in excessive trading

 .    change or discontinue its exchange privilege, or temporarily suspend this
     privilege during unusual market conditions

 .    delay sending out redemption proceeds for up to seven days (generally
     applies only in cases of very large redemptions, excessive trading or
     during unusual market conditions)

LOGO      DISTRIBUTION AND TAXES
- --------------------------------

          The amount of dividends of net investment income and distributions of
          net realized long and short-term capital gains payable to shareholders
          will be determined separately for the Fund. Dividends from the net
          investment income of the Fund will be declared and paid annually.  The
          Fund will distribute any net realized long or short-term capital gains
          at least annually.  Your distributions will be reinvested in the Fund
          unless you instruct the Fund otherwise.  There are no fees or sales
          charges on reinvestments.

          In any fiscal year in which the Fund qualifies as a regulated
          investment company and distribute to shareholders all of their net
          investment income and net capital gains, the Fund is relieved of
          Federal income tax.

          Generally, all dividends and capital gains are taxable whether they
          are reinvested or received in cash - unless you are exempt from
          taxation or entitled to tax deferral.  Capital gains distributions may
          be taxable at different rates depending on the length of time the Fund
          has held the assets sold.  Early each year, you will be notified as to
          the amount and Federal tax status of all distributions paid during the
          prior year.  Distributions may also be subject to state or local
          taxes.  The tax treatment of redemptions from a retirement plan
          account may differ from redemptions from an ordinary shareholder
          account.  If you redeem shares of the Fund or exchange them for shares
          of another Fund, any gain on the transaction may be subject to tax.
          You must provide the Fund with a correct taxpayer identification
          number (generally your Social Security Number) and certify that you
          are not subject to backup withholding.  If you fail to do so, the IRS
          can require the Fund to withhold 31% of your taxable distributions and
          redemptions.  Federal law also requires the Fund to withhold 30% or
          the applicable tax treaty rate from dividends paid to nonresident
          alien, non-U.S. partnership and non-U.S. corporation shareholder
          accounts.

          This is a brief summary of some of the tax laws that affect your
          investment in the Fund.  Please see the Statement of Additional
          Information and your tax adviser for further information.

          The financial highlights table is intended to help you understand the
          Fund's financial performance for the fiscal years indicated.  Certain
          information reflects financial results for a single Fund share.
          "Total return" shows how much your investment in the Institutional
          Class shares of the Fund would have increased (or decreased) during
          each period, assuming you had reinvested all dividends and
          distributions (Class N shares commenced operations on March 1, 1999).
          These figures have been audited by Deloitte & Touche LLP, whose

INVESTMENT OBJECTIVES AND PRINCIPAL STRATEGIES
- --------------------------------------------------------------------------------
 
The Fund is affected by changes in the economy, or in securities and other
markets. There is also the possibility that investment decisions the Adviser
makes will not accomplish what they were designed to achieve or that companies
in which the Fund invests will have disappointing performance or not pay their
debts.

</TABLE>

Under adverse market conditions, the Fund could invest some or all of its assets
in money market securities.  Although the Fund would do this only in seeking to
avoid losses, it could have the effect of reducing the benefit from any upswing
in the market.

                                PRINCIPAL RISKS 
- --------------------------------------------------------------------------------
     
Risk is the chance that you will lose money on your investment or that it will
not earn as much as you expect. In general, the greater the risk, the more money
your investment can earn for you-and the more you can lose. Since shares of the
Fund represent an investment of securities with fluctuating market prices, the
value of Fund shares will vary as the Fund's portfolio securities increase or
decrease. Therefore, the value of an investment in the Fund could go down as
well as up. All investments are subject to:      
     
 .  MARKET RISK      
 
   There is the possibility that the returns from the types of securities in
   which the Fund invests will underperform returns from the various general
   securities markets or different asset classes. Different types of securities
   tend to go through cycles of outperformance and underperformance in
   comparison to the general securities markets.
   
 .  SECURITIES SELECTION RISK
 
   There is the possibility that the specific securities held in the Fund's
   portfolio will underperform other funds in the same asset class or benchmarks
   that are representative of the general performance of the asset class because
   of the portfolio manager's choice of securities.
   
 .  PRICE VOLATILITY
 
   There is the possibility that the value of the Fund's portfolio will change
   as the prices of its investments go up or down. Although stocks offer the
   potential for greater long-term growth than most fixed income securities,
   stocks generally have higher short-term volatility.
   
The Fund may also be subject to the following risk:
 
 .  FOREIGN INVESTING RISK
     
   There is the likelihood that foreign investments may be riskier than U.S.
   investments because of a lack of political stability, foreign controls on
   investment and currency exchange rates, fluctuations in currency exchange
   rates, withholding taxes, and a lack of adequate company information. The
   Fund is subject to foreign investing risk because it may invest in foreign
   company securities. In addition, because foreign securities generally are
   denominated and pay dividends or interest in foreign currencies, and the Fund
   may hold various foreign currencies, the value of the net assets of the Fund
   as measured in U.S. dollars can be affected favorably or unfavorably by
   changes in exchange rates.     

                                       4
<PAGE>
 
- --------------------------------------------------------------------------------
PRINCIPAL RISKS
- --------------------------------------------------------------------------------

Because the Fund is non-diversified for 1940 Act purposes, it may invest more
than 5% of its total assets in the securities of any one issuer. Consequently,
its exposure to credit and market risks associated with that issuer is
increased. 
    
Your investment is not a bank deposit, and it is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE SUMMARY
- --------------------------------------------------------------------------------
     
The two tables below show the Fund's annual returns and its long-term
performance with respect to its Institutional Class shares (Class N shares of
the Fund commenced operations on March 1, 1999). The first table shows you how
the Fund's performance has varied from year to year. The second compares the
Fund's performance over time to that of a broad-based securities index. Both
tables assume reinvestment of dividends and distributions. The performance
information includes performance of the predecessor limited partnership, which
was managed by a predecessor of TCW Funds Management, Inc. using the same
investment strategy as the Fund. The performance of the partnership was
calculated using performance standards applicable to private investment
partnerships which take into account all elements of total return and reflect
the deduction of all fees and expenses of operation. The predecessor limited
partnership, was not registered under the Investment Company Act of 1940 ("1940
Act") and therefore, was not subject to certain investment restrictions imposed
by the 1940 Act and Subchapter M of the Internal Revenue Code of 1986, as
amended. If the limited partnership had been registered under the 1940 Act its
performance could have been adversely affected. As with all mutual funds, past
performance is not a prediction of future results.

Expense Example

This Example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other mutual funds.
    
This Example shows what you could pay in expenses over time. It uses the same
hypothetical conditions other funds use in their prospectuses: $10,000 Initial
Investment, 5% total return each year and no changes in expenses. The figures
shown would be the same whether or not you sold your shares at the end of a
period. Because actual return and expenses will be higher or lower, the Example
is for comparison purposes only.

LOGO      INVESTMENT OBJECTIVES/APPROACH
          ------------------------------

Concepts to understand
- ----------------------

Large capitalization companies are established companies that are considered 
known quantities. Large capitalization companies often have the resources to 
weather economic shifts, although they can be slower to innovate than small 
companies.

Growth companies are companies exhibiting faster than average gains in earnings 
and which are expected to continue to show high levels of growth gain.
    
          The Fund seeks long-term capital appreciation.  To pursue this goal,
          it invests primarily in equity securities of large capitalization U.S.
          companies with above-average earnings prospects.  It will invest
          (except when maintaining a temporary defensive position) at least 65%
          of the value of total assets in companies with a market capitalization
          of greater than $3 billion at the time of purchase.     

          In managing the Fund's investments, the Adviser seeks to invest in
          companies that will have reported earnings that exceed analysts'
          expectations (i.e., potential for earnings surprises).  The Adviser
                        ----                                                 
          utilizes "bottom-up" fundamental research to identify these companies.
          The Adviser performs fundamental research by using techniques such as:

          .  making company visits
          .  attending industry conferences
          .  maintaining communication with company management
          
          The Adviser then uses the information that it has obtained from its
          fundamental research to analyze the company's long-term growth
          potential, future earnings and cash flow.

          The Adviser uses quantitative and qualitative screening criteria to
          determine which companies to subject to its fundamental analysis.
          
          Wendy S. Barker and Douglas S. Foreman are the Fund's portfolio
          managers.

<PAGE>
 
LOGO      MAIN RISKS
          ----------

          The Fund holds primarily stocks, which may go up or down in value,
          sometimes rapidly and unpredictably. Although stocks offer the
          potential for greater long-term growth than most fixed income
          securities, stocks generally have higher short-term volatility.  In
          addition, the Fund may hold convertible debt securities.  Many
          convertible debt securities are rated below investment grade and are
          considered speculative by rating agencies as to repayment of principal
          and interest.

          The primary risk affecting this Fund is "price volatility."  Price
          volatility refers to the possibility that the value of the Fund's
          portfolio will change as the prices of its investments go up or down.
          This Fund may be less susceptible to price volatility risk because it
          invests in the securities of large companies.  This is especially true
          during periods of economic uncertainty or during economic downturns.

          The Fund seeks to earn additional income by making loans of its
          portfolio securities to brokers, dealers and other financial
          institutions.  The loans will be secured at all times by cash and
          liquid high grade debt obligations.  As with any extension of credit,
          there are risks of delay in recovery and in some cases even loss of
          rights in the collateral should the borrower fail financially.
    
          The Fund may engage in active portfolio management which may result in
          increased Fund transaction expenses and have tax consequences such as
          increased realized gains for investors.

          -------------------

General Investment Risk
- -----------------------

Since shares of the Fund represent an investment in securities with fluctuating
market prices, the value of Fund shares will vary as the value of the Fund's
portfolio securities increases or decreases. Therefore, the value of an
investment in the Fund could go down as well as up.

         Please consider the following risks before investing in the Fund.

          Various market risks can affect the price or liquidity of an issuer's
          securities.  Adverse events occurring with respect to an issuer's
          performance or financial position can depress the value of the
          issuer's securities.  The liquidity in a market for a particular
          security will affect its value and may be affected by factors relating
          to the issuer, as well as the depth of the market for that security.
          Other market risks that can affect value include a market's current
          attitudes about types of securities, market reactions to political or
          economic events, and tax and regulatory effects (including lack of
          adequate regulations for a market or particular type of instrument).
          Market restrictions on trading volume can also affect price and
          liquidity.

          Prices of many securities tend to be more volatile in the short-term.
          Therefore an investor who trades frequently or redeems in the short-
          term is more likely to incur loss than an investor who holds
          investments for the longer term  The fewer the number of issuers in
          which a Fund invests, the greater the potential volatility of its
          portfolio.
    
          The Adviser may temporarily invest up to 100% of the Fund's assets in
          high quality, short-term money market instruments if it believes
          adverse economic or market conditions, such as excessive volatility or
          sharp market declines, justify taking a defensive investment posture.
          If the Fund attempts to limit investment risk by temporarily taking a
          defensive investment position, it may be unable to pursue its
          investment objective during that time, and it may miss out on some or
          all of an upswing in the securities markets.

Foreign Investing
- -----------------

          Investment in foreign securities involves special risks in addition to
          the usual risks inherent in domestic investments.  These include:
          political or economic instability; the unpredictability of
          international trade patterns; the possibility of foreign governmental
          actions such as expropriation, nationalization or confiscatory
          taxation; the imposition or modification of foreign currency or
          foreign investment controls; the imposition of withholding taxes on
          dividends, interest and gains; price volatility; and fluctuations in
          currency exchange rates.
    
          As compared to U.S. companies, foreign issuers generally disclose less
          financial and other information publicly and are subject to less
          stringent and less uniform accounting, auditing and financial
          reporting standards. Foreign countries typically impose less thorough
          regulations on brokers, dealers, stock exchanges, insiders and listed
          companies than does the U.S., and foreign securities markets may be
          less liquid and more volatile than domestic markets. Investment in
          foreign securities involves higher costs than investment in United
          States securities, including higher transaction and custody costs as
          well as the imposition of additional taxes by foreign governments. In
          addition, security trading practices abroad may offer less protection
          to investors such as the Fund. Settlement of transactions in some
          foreign markets may be delayed or may be less frequent than in the
          U.S., which could affect the liquidity of the Fund's portfolio. Also,
          it may be more difficult to obtain and enforce legal     

                                       12
<PAGE>
 
          judgments against foreign corporate issuers than against domestic
          issuers and it may be impossible to obtain and enforce judgments
          against foreign governmental issuers.
    
          Because foreign securities generally are denominated and pay dividends
          or interest in foreign currencies, and the Fund may hold various
          foreign currencies from time to time, the value of the net assets of
          the Fund as measured in U.S. dollars can be affected favorably or
          unfavorably by changes in exchange rates. Generally, currency exchange
          transactions will be conducted on a spot (i.e., cash) basis at the
          spot rate prevailing in the currency exchange market. The cost of
          currency exchange transactions will generally be the difference
          between the bid and offer spot rate of the currency being purchased or
          sold. In order to protect against uncertainty in the level of future
          foreign currency exchange rates, the Fund is authorized to enter into
          certain foreign currency futures and forward contracts. However, it is
          not obligated to do so and, depending on the availability and cost of
          these devices, the Fund may be unable to use foreign currency futures
          and forward contracts to protect against currency uncertainty. Please
          see the Statement of Additional Information for further
          information.    
    
          The forward currency market for the purchase or sale of U.S. dollars
          in most countries is not highly developed, and in certain countries,
          there may be no such market. If a devaluation of a currency is
          generally anticipated, the Fund may not be able to contract to sell
          the currency at an exchange rate more advantageous than that which
          would prevail after the anticipated amount of devaluation. In the
          event the Fund holds securities denominated in a currency that suffers
          a devaluation, the Fund's net asset values will suffer corresponding
          reductions. In this regard, in December 1994, the Mexican government
          determined to allow the Mexican peso to trade freely against the U.S.
          dollar rather than within a controlled band, which action resulted in
          a significant devaluation of the Mexican peso against the dollar.
          Further, in July 1997, the Thai and Philippine governments allowed the
          baht and peso, respectively, to trade freely against the United States
          dollar resulting in a sharp devaluation of both currencies, and in
          1998 Russia did the same, causing a sharp devaluation of the
          ruble.

LOGO      RISK CONSIDERATIONS
          -------------------
    
Fixed Income Securities     
- ----------------------- 

          Fixed income securities are subject to various risks.  The two primary
          (but not exclusive) risks affecting fixed income instruments are
          "credit risk" and "interest rate risk."  These risks can affect a
          security's price volatility to varying degrees, depending upon the
          nature of the instrument.  In addition, the depth and liquidity of the
          market for an individual or class of fixed income security can also
          affect its price and, hence, the market value of the Fund.

         
          "Credit risk" refers to the likelihood that an issuer will default in
          the payment of principal and/or interest on an instrument.  Financial
          strength and solvency of an issuer are the primary factors influencing
          credit risk.  In addition, lack of or inadequacy of collateral or
          credit enhancements for a fixed income security may affect its credit
          risk.  Credit risk of a security may change over its life, and
          securities which are rated by rating agencies are often reviewed and
          may be subject to downgrade.
    
          The Fund may invest in convertible securities rated below investment
          grade.  Debt securities that are rated below investment grade are
          considered to be speculative; they are also commonly known as "junk"
          bonds.  Generally, lower-rated debt securities provide a higher yield
          than higher rated debt securities of similar maturity but are subject
          to greater credit risk than higher rated securities of similar
          maturity.  Such securities are regarded as predominantly speculative
          with respect to the issuer's continuing ability to meet principal and
          interest payments.  Because investment in lower quality securities
          involves      

                                       14
<PAGE>
 
          greater investment risk, achievement of the Fund's investment
          objective will be more dependent on the Adviser's analysis than would
          be the case if the Fund were investing in higher quality bonds. In
          addition, lower quality securities may be more susceptible to real or
          perceived adverse economic and individual corporate developments than
          would investment grade bonds. Moreover, the secondary trading market
          for lower quality securities may be less liquid than the market for
          investment grade bonds. This potential lack of liquidity may make it
          more difficult for the Adviser to value accurately certain portfolio
          securities.

          "Interest rate risk" refers to the risks associated with market
          changes in interest rates.  Interest rate changes may affect the value
          of a fixed income security directly (especially in the case of fixed
          rate securities) and indirectly (especially in the case of adjustable
          rate securities).  In general, rises in interest rates will negatively
          impact the price of fixed rate securities and falling interest rates
          will have a positive effect on price.  The degree to which a
          security's price will change as a result of changes in interest rates
          is measured by its "duration."  For example, the price of a bond with
          a 5 year duration would be expected under normal market conditions to
          decrease 5% for every 1% increase in interest rates.  Generally,
          securities with longer maturities have a greater duration and thus are
          subject to greater price volatility from changes in interest rates.
          Adjustable rate instruments also react to interest rate changes in a
          similar manner although generally to a lesser degree (depending,
          however, on the characteristics of the reset terms, including the
          index chosen, frequency of reset and reset caps or floors, among other
          things).

Non-Diversified Status
- ----------------------

          The Fund is non-diversified for 1940 Act purposes and as such may
          invest a larger percentage of its assets in individual issuers than a
          diversified investment company. In this regard, the Fund is not
          subject to the general limitation that it not invest more than 5% of
          its total assets in the securities of any one issuer. To the extent
          the Fund makes investments in excess of 5% of its assets in a
          particular issuer, its exposure to credit and market risks associated
          with that issuer is increased. However, the Fund's investments will be
          limited so as to qualify for the special tax treatment afforded
          "regulated investment companies" under the Internal Revenue Code of
          1986, as amended.

Year 2000
- ---------
    
          The investment advisory and management services provided by the
          Adviser and the services provided to shareholders by the Transfer
          Agent depend on the smooth functioning of their computer systems.
          Many computer software systems in use today cannot recognize the year
          2000, but revert to 1900 or some other date, due to the manner in
          which dates were encoded and calculated.  That failure could have a
          negative impact on the handling of securities trades, pricing and
          account services.  The Adviser and the Transfer Agent have been
          actively working on necessary changes to their own computer systems to
          prepare for the year 2000 and expect that their systems will be
          adapted for year 2000 compliance before that date, but there can be no
          assurance that they will be successful, or that interaction with other
          non-complying computer systems will not impair their services at that
          time.  The Adviser has been, and is currently in contact with each of
          its External Service Providers to evaluate their readiness for the
          year 2000.  The Adviser has requested each of its External Service
          Providers to either (i) prepare a description of its process for
          identifying date sensitive areas, its approach for implementing
          changes, its testing methodology, along with its timetable for
          completion, or (ii) certify as to its year 2000 compliance.     

          In addition, it is possible that the markets for securities in which
          the Fund invests may be negatively affected by computer failures
          throughout the financial services industry commencing January 1, 2000.
          Improperly functioning trading systems may result in settlement
          problems.  In addition, corporate and governmental data processing
          errors may result in production problems for individual companies and
          create overall economic uncertainties.  Earnings of individual issuers
          will be affected by remediation costs which may be substantial.

          Individual firms may further experience disruptions to their business
          due to the failure of their counterparts to address year 2000
          problems, or could experience further disruption to the economy at
          large, which could adversely affect corporate earnings generally and
          the value of their securities.  Accordingly, the Fund's portfolio
          investments may be negatively affected.

LOGO      RISK CONSIDERATIONS
          -------------------

European Economic and Monetary Union
- ------------------------------------
    
          The Fund may invest in European countries that have agreed to enter
          into the European Monetary Union (EMU).  EMU is an effort by certain
          European countries to, among other things, reduce barriers between
          countries and eliminate fluctuations in their currencies.  Among other
          things, EMU establishes a single European currency (the euro), which
          was introduced on January 1, 1999 and is expected to replace the
          existing national currencies of all initial EMU participants by July
          1, 2002. Upon introduction of the euro, certain securities (beginning
          with government and corporate bonds) have been redonominated in the
          euro and, thereafter will trade and make dividend and other payments
          only in euros.     
    
          Like other investment companies and business organizations, including
          the companies in which the Fund invests, the Fund could be adversely
          affected: (i) if the euro, or EMU as a whole does not take affect; 
          (ii) if a participating country withdraws from EMU; or (iii) if the
          computing, accounting and trading systems used by the Fund's service
          providers, or by other business entities with which the Fund or its
          service providers do business, are not capable of recognizing the euro
          as a distinct currency at the time of, and following euro 
          conversion.

          Investment Adviser

          The Fund's investment adviser is TCW Funds Management, Inc. (the
          "Adviser") and is headquartered at 865 South Figueroa Street, Suite
          1800, Los Angeles, California 90017. As of December 31, 1998, the
          Adviser and its affiliated companies, which provide a variety of
          trust, investment management and investment advisory services, had
          over $50 billion under management or committed for management.

          Advisory Agreement


          The Company and the Adviser have entered into an Investment Advisory
          and Management Agreement (the "Advisory Agreement"), under the terms
          of which the Company has employed the Adviser to manage the investment
          of its assets, to place orders for the purchase and sale of its
          portfolio securities, and to be responsible for overall management of
          the Company's business affairs, subject to control by the Board of
          Directors of the Company.  The Adviser also pays certain costs of
          marketing the Fund, including sales personnel compensation, from
          legitimate profits from its investment advisory fees and other
          resources available to it. Under the Advisory Agreement, the Fund pays
          to the Adviser as compensation for the services rendered, facilities
          furnished, and expenses paid by it the following fees:

          The Advisory Agreement provides that the Adviser shall not be liable
          for any error of judgment or mistake of law or for any loss suffered
          by the Fund in connection with the matters to which the agreement
          relates, except a loss resulting from willful misfeasance, bad faith
          or gross negligence on the part of the Adviser in the performance of
          its duties or from reckless disregard by the Adviser of its duties
          under the agreement.

LOGO      MULTIPLE CLASS STRUCTURE
          ------------------------

          The Fund currently offers two classes of shares, Institutional Class
          shares and Class N shares.  Shares of each class of the Fund represent
          an equal pro rata interest in the Fund and generally gives you the
          same voting, dividend, liquidation, and other rights.  The
          Institutional Class shares are offered at the current net asset value.
          The Class N shares are also offered at the current net asset value,
          but will be subject to fees imposed under a distribution plan
          ("Distribution Plan") adopted pursuant to Rule 12b-1 under the
          Investment Company Act of 1940, as amended.  Pursuant to the
          Distribution Plan, the Fund compensates the Fund's distributor at a
          rate equal to 0.25% of the average daily net assets of the Fund
          attributable to its Class N shares for distribution and related
          services.  Because these fees are paid out of the Fund's Class N
          assets on an on-going basis, over time, these fees will increase the
          cost of your investment and may cost you more than paying other types
          of sales charges.

LOGO      ACCOUNT POLICIES AND SERVICES
          -----------------------------

          Buying shares
    
          You pay no sales charges to invest in the Fund.  Your price for Fund
          shares is the Fund's net asset value per share (NAV) which is
          calculated as of the close of trading on the New York Stock Exchange
          (usually 4:00 p.m. Eastern time) every day the exchange is open. Your
          order will be priced at the next NAV calculated after your order is
          accepted by the Fund. Orders received by the Fund's Transfer Agent
          from dealers, brokers or other service providers after the NAV for the
          day is determined that day will receive that same day's NAV if the
          orders were received by the dealers, brokers or service providers from
          their customers prior to 4:00 p.m. and were transmitted to and
          received by the Transfer Agent prior to 8:00 a.m. Eastern time on the
          next day. The Fund's investments are valued based on market value, or
          where market quotations are not readily available, based on fair value
          as determined in good faith by the Fund pursuant to procedures
          established by the Fund's board.

          Selling shares

          You may sell shares at any time.  Your shares will be sold at the next
          NAV calculated after your order is accepted by the Fund's Transfer
          Agent.  Any certificates representing Fund shares being sold must be
          returned with your redemption request.  Your order will be processed
          promptly, and you will generally receive the proceeds within a week.

          Before selling recently purchased shares, please note that if the Fund
          has not yet collected payment for the shares you are selling, it may
          delay sending the proceeds for up to fifteen days.

          Written sell order

          Some circumstances require written sell orders, along with signature
          guarantees.  These include:

          .  amounts of $100,000 or more

          .  amounts of $1,000 or more on accounts whose address has been 
             changed within the last 30 days
 
          .  requests to send the proceeds to a payee or address different than
             what is on our records

          A signature guarantee helps protect against fraud.  You can obtain one
          from most banks or securities dealers but not from a notary public.
          Please call us to ensure that your signature guarantee will be
          processed correctly.

          Exchange privilege

          You can exchange from one Class N Galileo Fund into another.  You can
          request your exchange in writing or by phone.  Be sure to read the
          current prospectus for any Fund into which you are exchanging.  Any
          new account established through an exchange will have the same
          privileges as your original account (as long as they are available).

          Third Party Transactions

          You may buy and redeem Fund shares through certain broker-dealers and
          financial organizations and their authorized intermediaries.  If
          purchases and redemptions of Fund shares are arranged and settlement
          is made at an investor's election through a registered broker-dealer,
          other than the Fund's distributor, that broker-dealer may, at its
          discretion, charge a fee for that service.

LARGE REDEMPTION AMOUNTS
- ------------------------

The Fund also reserves the right to make a "redemption in kind" -- payment in
portfolio securities rather than cash -- if the amount you are redeeming in any
90-day period is large enough to affect Fund operations (for example, if it
equals more than $250,000 or represents more than 1% of the Fund's assets).     

         Account statements

         Every Galileo investor automatically receives regular account
         statements. You will also be sent a yearly statement detailing the tax
         characteristics of any dividends and distributions you have received.

         General policies

         If your account falls below $1,000 as a result of redemptions and or
         exchanges for six months or more, the Fund may close your account and
         send you the proceeds upon 60 days' written notice.

         Unless you decline telephone privileges on your New Account Form, you
         may be responsible for any fraudulent telephone order as long as the
         Transfer Agent takes reasonable measures to verify the order.

         

     The Fund restricts excessive trading (usually defined as more than four
     exchanges out of the Fund within a calendar year).  You are limited to one
     exchange of shares in the Fund during any 15-day period except investors in
     401(k) and other group retirement accounts, investors who purchase shares
     through certain broker-dealers and asset allocation accounts managed by the
     Adviser or an affiliate.  The Fund reserves the right to:

     .  refuse any purchase or exchange request that could adversely affect the
        Fund or its operations, including those from any individual or group 
        who, in the Fund's view, are likely to engage in excessive trading

     .  change or discontinue its exchange privilege, or temporarily suspend 
        this privilege during unusual market conditions

     .  delay sending out redemption proceeds for up to seven days (generally 
        applies only in cases of very large redemptions, excessive trading or 
        during unusual market conditions)

LOGO      DISTRIBUTIONS AND TAXES
          -----------------------

          The amount of dividends of net investment income and distributions of
          net realized long and short-term capital gains payable to shareholders
          will be determined separately for the Fund. Dividends from the net
          investment income of the Fund will be declared and paid annually.  The
          Fund will distribute any net realized long or short-term capital gains
          at least annually.  Your distributions will be reinvested in the Fund
          unless you instruct the Fund otherwise.  There are no fees or sales
          charges on reinvestments.

          In any fiscal year in which the Fund qualifies as a regulated
          investment company and distributes to shareholders all of its net
          investment income and net capital gains, the Fund is relieved of
          Federal income tax.

          Generally, all dividends and capital gains are taxable whether they
          are reinvested or received in cash - unless you are exempt from
          taxation or entitled to tax deferral.  Capital gains distributions may
          be taxable at different rates depending on the length of time the Fund
          has held the assets sold.  Early each year, you will be notified as to
          the amount and Federal tax status of all distributions paid during the
          prior year.  Distributions may also be subject to state or local
          taxes.  The tax treatment of redemptions from a retirement plan
          account may differ from redemptions from an ordinary shareholder
          account.  If you redeem shares of the Fund or exchange them for shares
          of another Fund, any gain on the transaction may be subject to tax.
          You must provide the Fund with a correct taxpayer identification
          number (generally your Social Security Number) and certify that you
          are not subject to backup withholding.  If you fail to do so, the IRS
          can require the Fund to withhold 31% of your taxable distributions and
          redemptions.  Federal law also requires the Fund to withhold 30% or
          the applicable tax treaty rate from dividends paid to nonresident
          alien, non-U.S. partnership and non-U.S. corporation shareholder
          accounts.

          This is a brief summary of some of the tax laws that affect your
          investment in the Fund.  Please see the Statement of Additional
          Information and your tax adviser for further information.

          The financial highlights table is intended to help you understand the
          Fund's financial performance for the fiscal years indicated.  Certain
          information reflects financial results for a single Fund share.
          "Total return" shows how much your investment in the Institutional
          Class shares of the Fund would have increased (or decreased) during
          each period, assuming you had reinvested all dividends and
          distributions (Class N shares commenced operations on March 1, 1999).
          These figures have been audited by Deloitte & Touche LLP, whose

INVESTMENT OBJECTIVES AND PRINCIPAL STRATEGIES
- --------------------------------------------------------------------------------

The Fund is affected by changes in the economy, or in securities and other
markets. Additionally, changes in interest rates will affect not only the
current return on the Fund, but the value of the capital investment will most
likely fluctuate up or down. There is also the possibility that investment
decisions the Adviser makes will not accomplish what they were designed to
achieve or that companies in which the Fund invests will have disappointing
performance or not pay their debts.

 Under adverse market conditions, the Fund could invest some or all of its
 assets in money market securities.  Although the Fund would do this only when
 seeking to avoid losses, it could have the effect of reducing the benefit from
 any upswing in the market.

PRINCIPAL RISKS
- --------------------------------------------------------------------------------

Risk is the chance that you will lose money on your investment or that it will
not earn as much as you expect. In general, the greater the risk, the more money
your investment can earn for you and the more you can lose. Since shares of the
Fund represent an investment in securities with fluctuating market prices, the
value of fund shares will vary as the value of the Fund's portfolio securities
increases or decreases in value. Therefore, the value of an investment in the
Fund could go down as well as up. All investments are subject to:
    
 .    MARKET RISK     
 
     There is the possibility that the returns from the types of securities in
     which the Fund invests will underperform returns from the various general
     securities markets or different asset classes. Different types of
     securities tend to go through cycles of outperformance and underperformance
     in comparison to the general securities markets.

 .    SECURITIES SELECTION RISK
 
     There is the possibility that the specific securities held in the Fund's
     portfolio will underperform the other funds in the same asset class or
     benchmarks that are representative of the general performance of the asset
     class because of the portfolio manager's choice of securities.
     
Because the Fund is a fixed income fund, the Fund may also be subject (in
varying degrees) to the following additional risks:
 
 .  CREDIT RISK
 
   There is the possibility that the Fund could lose money if an issuer is
   unable to meet its financial obligations such as the payment of principal
   and/or interest on an instrument, or goes bankrupt. The Fund is subject to
   some credit risk because it invests in private issued mortgage-backed
   securities.

 .  INTEREST RATE RISK
 
   There is the possibility that the value of the Fund's portfolio investments
   may fall since fixed income securities generally fall in value when interest
   rates rise. The longer the term of a fixed income instrument, the more
   sensitive it will be to fluctuations in value from interest rate changes.
   Changes in interest rates may have a significant effect on the Fund, because
   it may hold securities with long terms to maturity.
     
   In the case of mortgage-backed securities, rising interest rates tend to
   extend the term to maturity of the securities, making them even more
   susceptible to interest rate changes. When interest rates drop, not only can
   the value of fixed income securities drop, but the yield can drop,
   particularly where the yield on the fixed income securities is tied to
   changes in interest rates, such as adjustable mortgages. Also when interest
   rates drop, the holdings of mortgage-backed securities by the Fund can reduce
   returns if the owners of the underlying mortgages pay off their mortgages
   sooner than anticipated since the funds prepaid will have to be reinvested at
   the then lower prevailing rates. This is known as prepayment risk. When
   interest rates rise, the holdings of mortgage-backed securities by this Fund
   can reduce returns if the owners of the underlying mortgages pay off their
   mortgages later than anticipated. This is known as extension risk.

- --------------------------------------------------------------------------------
PRINCIPAL RISKS
- --------------------------------------------------------------------------------
 
 .  LIQUIDITY RISK
     
   There is the possibility that the Fund may lose money or be prevented from
   earning capital gains if it cannot sell a security at the time and price that
   is most beneficial to the Fund. The Fund is subject to liquidity risks
   because it invests in mortgage-backed securities, which have experienced
   periods of illiquidity.     
 
A more detailed explanation of these risks is presented under the "Risk
Considerations" section at page 12. 

Your investment is not a bank deposit, and it is not insured or guaranteed by
the Federal Deposit Insurance Corporation or any other government agency.

PERFORMANCE SUMMARY
- --------------------------------------------------------------------------------
     
The two tables below show the Fund's annual returns and its long-term
performance with respect to its Institutional Class shares (Class N shares of
the Fund commenced operations on March 1, 1999). The first table shows you how
the Fund's performance has varied from year to year. The second compares the
Fund's performance over time to that of a broad-based securities index. Both
tables assume reinvestment of dividends and distributions. The performance
information includes performance of the predecessor limited partnership, which
was managed by a predecessor of TCW Funds Management, Inc. using the same
investment strategy as the Fund. The performance of the partnership was
calculated using performance standards applicable to private investment
partnerships which take into account all elements of total return and reflect
the deduction of all fees and expenses of operation. The predecessor limited
partnership, was not registered under the Investment Company Act of 1940 ("1940
Act") and therefore, was not subject to certain investment restrictions imposed
by the 1940 Act and Subchapter M of the Internal Revenue Code of 1986, as
amended. If the limited partnership had been registered under the 1940 Act its
performance could have been adversely affected. As with all mutual funds, past
performance is not a prediction of future results.

This Example is intended to help you compare the cost of investing in the Fund
with the cost of investing in other mutual funds.
    
This Example shows what you could pay in expenses over time. It uses the same
hypothetical conditions other funds use in their prospectuses: $10,000 Initial
Investment, 5% total return each year and no changes in expenses. The figures
shown would be the same whether or not you sold your shares at the end of a
period. Because actual return and expenses will be higher or lower, the Example
is for comparison purposes only.

[LOGO] INVESTMENT OBJECTIVES/APPROACH     
       ------------------------------

Concepts to understand
- ----------------------

Duration is often used to measure the potential volatility of a bond's price: 
bonds with longer durations are more sensitive to changes in interest rates, 
making them more volatile than bonds with shorter durations. Bonds with fixed 
maturities have a readliy determinable duration. Bonds with uncertain payment
schedules, such as mortgage-backed securities which can be prepaid, have
durations which may vary or lengthen in certain interest rate environments,
making their value even more volatile than they were when acquired.
    
Weighted average duration is the average duration of the securities in the 
portfolio weighted by market value.     

Weighted average reset frequency is the average time to the next coupon reset 
date of the floating rate securities in the portfolio weighted by market value.

          The Fund seeks to maximize current income and achieve above average
          total return consistent with prudent investment management over a full
          market cycle.  To pursue these goals, the Fund invests primarily in
          mortgage-backed securities of any maturity or type guaranteed by, or
          secured by collateral that is guaranteed by, the United States
          Government, its agencies, instrumentalities or its sponsored
          corporations (collectively, the "Federal Agencies"), and in privately
          issued mortgage-backed securities rated Aa or higher by Moody's or AA
          or higher by S&P.
    
          The Fund will invest (except when maintaining a temporary defensive
          position) at least 65% of the value of its total assets in mortgage-
          backed securities which are guaranteed by, or secured by collateral
          which is guaranteed by Federal Agencies. In managing the Fund's
          investments, the Adviser seeks to construct a portfolio with a
          weighted-average duration for fixed rate securities and a weighted
          average reset frequency for floating rate securities of no more than
          eight years.    

          Philip A. Barach, Jeffrey E. Gundlach and Frederick H. Horton are the
          Fund's portfolio managers.

[LOGO]    MAIN RISKS
      --------------

          The primary risks affecting this Fund are "credit risk," "interest
          rate risk" (including "extension risk" and "prepayment risk"), and
          "liquidity risk."

          Credit risk refers to the likelihood that the Fund could lose money if
          an issuer is unable to meet its financial obligations, such as the
          payment of principal and/or interest on an instrument, or goes
          bankrupt.  The Fund may invest a portion of its assets in mortgage-
          backed securities which are not guaranteed by the U.S. Government,
          which may make the Fund subject to substantial credit risk. This is
          especially true during periods of economic uncertainty or during
          economic downturns.  Interest rate risk refers to the possibility that
          the value of the Fund's portfolio investments may fall since fixed
          income securities generally fall in value when interest rates rise.
          The longer the term of a fixed income instrument, the more sensitive
          it will be to fluctuations in value from interest rate changes.
          Changes in interest rates may have a significant effect on this Fund,
          because it may hold securities with long terms to maturity and
          mortgage-backed securities, including collateralized mortgage
          obligations, and stripped mortgage securities.  Because this Fund
          invests in mortgage-backed securities, it may be subject to extension
          risk and prepayment risk, which are both a type of interest rate risk.
          Extension risk is the possibility that rising interest rates may cause
          owners of the underlying mortgages to pay off their mortgages at a
          slower than expected rate.  This particular risk may effectively
          change a security which was considered short or intermediate term into
          a long-term security.  Long-term securities generally drop in value
          more dramatically in response to rising interest rates than short or
          intermediate-term securities.  Prepayment risk refers to the
          possibility that falling interest rates may cause owners of the
          underlying mortgages to pay off their mortgages at a faster than
          expected rate.  This tends to reduce returns since the funds prepaid
          will have to be reinvested at the then lower prevailing rates.
          Liquidity risk refers to the possibility that the Fund may lose money
          or be prevented from earning capital gains if it cannot sell a
          security at the time and price that is most beneficial to the Fund.
          Because mortgage-backed securities may be less liquid than other
          securities, the Fund may be more susceptible to liquidity risks than
          funds that invest in other securities.

          The Fund may invest some assets in inverse floaters and interest-only
          and principal-only securities, which are sometimes referred to as

                                       10
<PAGE>
 
     
          derivatives.  These practices may be used to increase returns;
          however, such practices sometimes may reduce returns or increase
          volatility and may be very sensitive to changes in interest 
          rates.     

          The Fund seeks to earn additional income by making loans of its
          portfolio securities to brokers, dealers and other financial
          institutions.  The loans will be secured at all times by cash and
          other liquid high-grade debt obligations.  As with any extension of
          credit, there are risks of delay in recovery and in some cases even
          loss of rights in the collateral should the borrower fail financially.
    
          The fund may engage in active portfolio management which may result in
          increased fund transaction expenses and have tax consequences such as
          increased realized gains for investors.

General Investment Risk
- -----------------------
    
Since shares of the Fund represent an investment in securities with fluctuating 
market prices, the value of Fund shares will vary as the value of the Fund's 
portfolio securities increases or decreases. Therefore, the value of an 
investment in the Fund could go down as well as up. This is also true for funds 
that invest primarily in fixed income securities. High credit quality
investments also react in value to interest rate changes.     

          Please consider the following risks before investing in the Fund.

          Various market risks can affect the price or liquidity of an issuer's
          securities.  Adverse events occurring with respect to an issuer's
          performance or financial position can depress the value of the
          issuer's securities.  The liquidity in a market for a particular
          security will affect its value and may be affected by factors relating
          to the issuer and the depth of the market for that security.  Other
          market risks that can affect value include a market's current
          attitudes about type of security, market reactions to political or
          economic events, and tax and regulatory effects (including lack of
          adequate regulations for a market or particular type of instrument).
          Market restrictions on trading volume can also affect price and
          liquidity.
    
          Prices of most securities tend to be more volatile in the short-term.
          Therefore, an investor who trades frequently or redeems in the short-
          term is more likely to incur loss than an investor who holds
          investments for the longer term.  The fewer the number of issuers in
          which a Fund invests, the greater the potential volatility of its
          portfolio.  Lack of diversification in a portfolio can also increase
          volatility and may be very sensitive to changes in interest 
          values.     
    
The Adviser may temporarily invest up to 100% of the Fund's assets in high
quality, short-term money market instruments if it believes adverse economic or
market conditions, such as excessive volatility or sharp market declines,
justify taking a defensive investment posture. If the Fund attempts to limit
investment risk by temporarily taking a defensive investment position, it may be
unable to pursue its investment objective during that time, and it may miss out
on some or all of an upswing in the securities markets.

Fixed Income Securities
- -----------------------


          Fixed income securities are subject to various risks.  The two primary
          (but not exclusive) risks affecting fixed income instruments are
          "credit risk" and "interest rate risk."  These risks can affect a
          security's price volatility to varying degrees, depending upon the
          nature of the instrument.  In addition, the depth and liquidity of the
          market for an individual or class of fixed income security can also
          affect its price and, hence, the market value of the Fund.

          "Credit risk" refers to the likelihood that an issuer will default in
          the payment of principal and/or interest on an instrument.  Financial
          strength and solvency of an issuer are the primary factors influencing
          credit risk.  In addition, lack of or inadequacy of collateral or
          credit enhancements for a fixed income security may affect its credit
          risk.  Credit risk of a security may change over its life and
          securities which are rated by rating agencies are often reviewed and
          may be subject to downgrades.

          "Interest rate risk" refers to the change in value of debt instruments
          associated with changes in interest rates.  Interest rate changes may
          affect the value of a fixed income security directly (especially in
          the case of fixed rate securities) and indirectly (especially in the
          case of adjustable rate securities).  In general, rises in interest
          rates will negatively impact the value of fixed rate securities and
          falling interest rates will have a positive effect on value.  The
          degree to which a security's price will change as a result of changes
          in interest rates is measured by its "duration."  For example, the
          price of a bond with a 5-year duration would be expected under normal
          market conditions to decrease 5% for every 1%

                                       13
<PAGE>
 
          increase in interest rates. Generally, securities with longer
          maturities have a greater duration and thus are subject to greater
          price volatility from changes in interest rates. Adjustable rate
          instruments also react to interest rate changes in a similar manner
          although generally to a lesser degree (depending, however, on the
          characteristics of the reset terms, including the index chosen,
          frequency of reset and reset caps or floors, among other things).

      -----------------------

Mortgage-Backed Securities
- --------------------------


          Credit and Market Risks of Mortgage-Backed Securities.  The
          investments by the Fund in fixed rate and floating rate mortgage-
          backed securities will entail normal credit risks (i.e., the risk of
                                                             ----             
          non-payment of interest and principal) and market risks (i.e., the
                                                                   ----     
          risk that interest rates and other factors will cause the value of the
          instrument to decline).  Many issuers or servicers of mortgage-backed
          securities guarantee timely payment of interest and principal on the
          securities, whether or not payments are made when due on the
          underlying mortgages.  This kind of guarantee generally increases the
          quality of a security, but does not mean that the security's market
          value and yield will not change.  Like bond investments, the value of
          fixed rate mortgage-backed securities will tend to rise when interest
          rates fall, and fall when rates rise.  Floating rate mortgage-backed
          securities will generally tend to have minimal changes in price when
          interest rates rise or fall, but their current yield will be affected.
          The value of all mortgage-backed securities may also change because of
          changes in the market's perception of the creditworthiness of the
          organization that issued or guarantees them.  In addition, the
          mortgage-backed securities market in general may be adversely affected
          by changes in governmental legislation or regulation.  Fluctuations in
          the market value of mortgage-backed securities after their acquisition
          usually do not affect cash income from these securities but are
          reflected in the Fund's net asset value. Factors that could affect the
          value of a mortgage-backed security include, among other things, the
          types and amounts of insurance which a mortgage carries, the amount of
          time the mortgage loan has been outstanding, the loan-to-value ratio
          of

                                       15
<PAGE>
 
          each mortgage and the amount of overcollateralization of a mortgage
          pool.

          Liquidity Risk of Mortgage-Backed Securities.  The liquidity of
          mortgage-backed securities varies by type of security; at certain
          times the Fund may encounter difficulty in disposing of investments.
          Because mortgage-backed securities may be less liquid than other
          securities, the Fund may be more susceptible to liquidity risks than
          funds that invest in other securities.  In the past, in stressed
          markets, certain types of mortgage-backed securities, such as inverse
          floaters, and interest-only securities, suffered periods of
          illiquidity if disfavored by the market.

          Prepayment, Extension and Redemption Risks of Mortgage-Backed
          Securities.  Mortgage-backed securities reflect an interest in monthly
          payments made by the borrowers who receive the underlying mortgage
          loans.  Although the underlying mortgage loans are for specified
          periods of time, such as 20 or 30 years, the borrowers can, and
          typically do, pay them off sooner.  When that happens, the mortgage-
          backed security which represents an interest in the underlying
          mortgage loan will be prepaid.  A borrower is more likely to prepay a
          mortgage which bears a relatively high rate of interest.  This means
          that in times of declining interest rates, a portion of the Fund's
          higher yielding securities are likely to be redeemed and the Fund will
          probably be unable to replace them with securities having as great a
          yield.  Prepayments can result in lower yields to shareholders.  The
          increased likelihood of prepayment when interest rates decline also
          limits market price appreciation of mortgage-backed securities.  This
          is known as prepayment risk.  Mortgage-backed securities are also
          subject to extension risk.  Extension risk is the possibility that
          rising interest rates may cause prepayments to occur at a slower than
          expected rate.  This particular risk may effectively change a security
          which was considered short or intermediate term into a long-term
          security.  Long-term securities generally fluctuate more widely in
          response to changes in interest rates than short or intermediate-term
          securities.  In addition, a mortgage-backed security may be subject to
          redemption at the option of the issuer.  If a mortgage-backed security
          held by the Fund is called for redemption, the Fund will be required
          to permit the issuer to redeem or "pay-off" the security, which could
          have an adverse effect on the Fund's ability to achieve its investment
          objective.

                                       16

          Collateralized Mortgage Obligations.  There are certain risks
          associated specifically with collateralized mortgage obligations
          ("CMOs.")  CMOs are debt obligations collateralized by mortgage loans
          or mortgage pass-through securities.  The average life of CMOs is
          determined using mathematical models that incorporate prepayment
          assumptions and other factors that involve estimates of future
          economic and market conditions.  These estimates may vary from actual
          future results, particularly during periods of extreme market
          volatility.  Further, under certain market conditions, such as those
          that occurred in 1994, the average weighted life of certain CMOs may
          not accurately reflect the price volatility of such securities.  For
          example, in periods of supply and demand imbalances in the market for
          such securities and/or in periods of sharp interest rate movements,
          the prices of CMOs may fluctuate to a greater extent than would be
          expected from interest rate movements alone. CMOs issued by private
          entities are not obligations issued or guaranteed by the United States
          Government, its agencies or instrumentalities and are not guaranteed
          by any government agency, although the securities underlying a CMO may
          be subject to a guarantee.  Therefore, if the collateral securing the
          CMO, as well as any third party credit support or guarantees, is
          insufficient to make payment, the holder could sustain a loss.
    
          Stripped Mortgage Securities.  Part of the investment strategy of the
          Total Return Mortgage-Backed Securities Fund involves interest-only
          Stripped Mortgage Securities. These investments may be highly
          sensitive to changes in interest and tend to be less liquid than
          other CMOs. In addition, prepayments of the underlying mortgages
          likely would lower the Fund's returns from stripped securities it
          holds.    

          Inverse Floaters. The Fund invests in inverse floaters, a class of
          CMOs with a coupon rate that resets in the opposite direction from the
          market rate of interest to which it is indexed such as London
          Interbank Offered Rate (LIBOR) or COFI.  Any rise in the index rate
          (as a consequence of an increase in interest rates) causes a drop in
          the coupon rate of an inverse floater while any drop in the index rate
          causes an increase in the coupon of an inverse floater.  An inverse
          floater may behave like a security that is leveraged since its
          interest rate usually varies by a magnitude much greater than the
          magnitude of the change in the index rate of interest.  The "leverage-
          like" characteristics inherent in inverse floaters are associated with
          greater volatility in their market prices.

                                       17

          Adjustable Rate Mortgages.  ARMs contain maximum and minimum rates
          beyond which the mortgage interest rate may not vary over the lifetime
          of the security.  In addition, many ARMs provide for additional
          limitations on the maximum amount by which the mortgage interest rate
          may adjust for any single adjustment period.  Alternatively, certain
          ARMs contain limitations on changes in the required monthly payment.
          In the event that a monthly payment is not sufficient to pay the
          interest accruing on an ARM, any excess interest is added to the
          principal balance of the mortgage loan, which is repaid through future
          monthly payments.  If the monthly payment for such an instrument
          exceeds the sum of the interest accrued at the applicable mortgage
          interest rate and the principal payment required at such point to
          amortize the outstanding principal balance over the remaining term of
          the loan, the excess is utilized to reduce the then-outstanding
          principal balance of the ARM.

          Asset-Backed Securities.  Certain asset-backed securities do not have
          the benefit of the same security interest in the related collateral as
          do mortgage-backed securities; nor are they provided government
          guarantees of repayment.  Credit card receivables are generally
          unsecured, and the debtors are entitled to the protection of a number
          of state and federal consumer credit laws, many of which give such
          debtors the right to set off certain amounts owed on the credit cards,
          thereby reducing the balance due.  In addition, some issuers of
          automobile receivables permit the servicers to retain possession of
          the underlying obligations.  If the servicer were to sell these
          obligations to another party, there is a risk that the purchaser would
          acquire an interest superior to that of the holders of the related
          automobile receivables.

[LOGO]    RISK CONSIDERATIONS
      -----------------------

Year 2000
- ---------
    
          The investment advisory and management services provided by the
          Adviser and the services provided to shareholders by the Transfer
          Agent depend on the smooth functioning of their computer systems.
          Many computer software systems in use today cannot recognize the year
          2000, but revert to 1900 or some other date, due to the manner in
          which dates were encoded and calculated.  Such a failure could have a
          negative impact on the handling of securities trades, pricing and
          account services.  The Adviser and the Transfer Agent have been
          actively working on necessary changes to their own computer systems to
          prepare for the year 2000 and expect that their systems will be
          adapted for year 2000 compliance before that date, but there can be no
          assurance that they will be successful, or that interaction with other
          non-complying computer systems will not impair their services at that
          time.  The Adviser has been, and is currently, in contact with each of
          its External Service Providers to evaluate their readiness for the
          year 2000.  The Adviser has requested each of its External Service
          Providers to either; (i) prepare a description of its process for
          identifying date sensitive areas, its approach for implementing
          changes its testing methodology, along with its timetable for
          completion, or (ii) certify its year 2000 compliance.     

          In addition, it is possible that the markets for securities in which
          the Fund invests may be negatively affected by computer failures
          throughout the financial services industry commencing January 1, 2000.
          Improperly functioning trading systems may result in settlement
          problems.  In addition, corporate and governmental data processing
          errors may result in production problems for individual companies and
          create overall economic uncertainties.  Earnings of individual issuers

                                       19
<PAGE>
 
          will be affected by remediation costs which may be substantial.
          Individual firms may further experience disruptions to their business
          due to the failure of their counterparts to address approaching year
          2000 problems, or could experience further disruption to the economy
          at large, which could adversely affect corporate earnings generally
          and the value of their securities.  Accordingly, the Fund's portfolio
          investments may be negatively affected.

[LOGO]    MANAGEMENT OF THE FUND
      --------------------------

          Investment Adviser

          The Fund's investment adviser is TCW Funds Management, Inc. and is
          headquartered at 865 South Figueroa Street, Suite 1800, Los Angeles,
          California 90017.  As of December 31, 1998, the Adviser and its
          affiliated companies, which provide a variety of trust, investment
          management and investment advisory services, had over $50 billion
          under management or committed for management.

          Advisory Agreement

          The Company and the Adviser have entered into an Investment Advisory
          and Management Agreement (the "Advisory Agreement"), under the terms
          of which the Company has employed the Adviser to manage the investment
          of its assets, to place orders for the purchase and sale of its
          portfolio securities, and to be responsible for overall management of
          the

<PAGE>
 
          Company's business affairs, subject to control by the Board of
          Directors of the Company.  The Adviser also pays certain costs of
          marketing the Fund, including sales personnel compensation, from
          legitimate profits from its investment advisory fees and other
          resources available to it. Under the Advisory Agreement, the Fund pays
          to the Adviser as compensation for the services rendered, facilities
          furnished, and expenses paid by it the following fees:

</TABLE>

          The Advisory Agreement provides that the Adviser shall not be liable
          for any error of judgment or mistake of law or for any loss suffered
          by the Fund in connection with the matters to which the agreement
          relates, except a loss resulting from willful misfeasance, bad faith,
          gross negligence on the part of the Adviser in the performance of its
          duties or from reckless disregard by the Adviser of its duties under
          the agreement.

[LOGO]    MULTIPLE CLASS STRUCTURE
      ----------------------------

          The Fund currently offers two classes of shares, Institutional Class
          shares and Class N shares.  Shares of each class of the Fund represent
          an equal pro rata interest in that Fund and generally gives you the
          same voting, dividend, liquidation, and other rights.  The
          Institutional Class shares are offered at the current net asset value.
          The Class N shares are also offered at the current net asset value,
          but will be subject to service fees imposed under a distribution plan
          ("Distribution Plan") adopted pursuant to Rule 12b-1 under the
          Investment Company Act of 1940, as amended. Pursuant to the
          Distribution Plan, the Fund compensates its distributor at a rate
          equal to 0.25% of the average daily net assets of the Fund
          attributable to its Class N shares for distribution and related
          services.  Because these fees are paid out of the Fund's Class N
          assets on an on-going basis, over time, these fees will increase the
          cost of your investment and may cost you more than paying other types
          of sales charges.

[LOGO]    ACCOUNT POLICIES AND SERVICES
      ---------------------------------

          Buying shares
    
          You pay no sales charges to invest in the Fund. Your price for Fund
          shares is the Fund's net asset value per share (NAV) which is
          calculated as of the close of trading on the New York Stock Exchange
          (usually 4:00 p.m. Eastern time) every day the exchange is open. Your
          order will be priced at the next NAV calculated after your order is
          accepted by the Fund. Orders received by the Fund's Transfer Agent
          from dealers, brokers or other service providers after the NAV for the
          day is determined, will receive that same day's NAV if the orders were
          received by the dealers, brokers or service providers from their
          customers prior to 4:00 p.m. and were transmitted to and received by
          the Transfer Agent prior to 8:00 a.m. Eastern time on the next day.
          The Fund's investments are valued based on market value, or where
          market quotations are not readily available, based on fair value as
          determined in good faith by the Fund pursuant to procedures
          established by the Fund's Board.

          Selling shares

          You may sell shares at any time.  Your shares will be sold at the next
          NAV calculated after your order is accepted by the Fund's Transfer
          Agent.  Any certificates representing Fund shares being sold must be
          returned with your redemption request.  Your order will be processed
          promptly and you will generally receive the proceeds within a week.

          Before selling recently purchased shares, please note that if the Fund
          has not yet collected payment for the shares you are selling, it may
          delay sending the proceeds for up to fifteen  days.

          Written sell order

          Some circumstances require written sell orders, along with signature
          guarantees.  These include:

          .  amounts of $100,000 or more

          .  amounts of $1,000 or more on accounts whose address has been
             changed within the last 30 days

          .  requests to send the proceeds to a payee or address different than
             what is on our records

          A signature guarantee helps protect against fraud.  You can obtain one
          from most banks or securities dealers but not from a notary public.
          Please call us to ensure that your signature guarantee will be
          processed correctly.

         

          Exchange privilege

          You can exchange from one Class N Galileo Fund into another.  You can
          request your exchange in writing or by phone.  Be sure to read the
          current prospectus for any Fund into which you are exchanging.  Any
          new account established through an exchange will have the same
          privileges as your original account (as long as they are available).

                                       24
<PAGE>
 
          Third Party Transactions

          You may buy and redeem Fund shares through certain broker-dealers and
          financial organizations and their authorized intermediaries.  If
          purchases and redemptions of Fund shares are arranged and settlement
          is made at an investor's election through a registered broker-dealer,
          other than the Fund's distributor, that broker-dealer may, at its
          discretion, charge a fee for that service.

          Account statements

          Every investor automatically receives regular account statements.  You
          will also be sent a yearly statement detailing the tax characteristics
          of any dividends and distributions you have received.

          General policies

          If your account falls below $1,000 as a result of redemptions and or
          exchanges for six months or more, the Fund may close your account and
          send you the proceeds upon 60 days' written notice.

LARGE REDEMPTION AMOUNTS
- ------------------------

The Fund also reserves the right to make a "redemption in kind"-payment in 
portfolio securities rather than cash-if the amount you are redeeming in any 
90-day period is large enough to affect Fund operations (for example, if it 
equals more than $250,000 or represents more than 1% of the Fund's assets).

          Unless you decline telephone privileges on your New Account Form, you
          may be responsible for any fraudulent telephone order as long as the
          Transfer Agent takes reasonable measures to verify the order.
    
          The Fund restricts excessive trading (usually defined as more than
          four exchanges out of the Fund within a calendar year).  You are
          limited to one exchange of shares in the Fund during any 15-day period
          except investors in 401(k) and other group retirement accounts,
          investors who purchase shares through certain broker-dealers and asset
          allocation accounts managed by the Adviser or an affiliate. The Fund
          reserves the right to:     

          .  refuse any purchase or exchange request that could adversely affect
             the Fund or its operations, including those from any individual or
             group who, in the Fund's view, are likely to engage in excessive
             trading

                                       25
<PAGE>
 
     
          .  change or discontinue its exchange privilege, or temporarily
             suspend this privilege during unusual market conditions.      
    
          .  delay sending out redemption proceeds for up to seven days
             (generally applies only in cases of very large redemptions,
             excessive trading or during unusual market conditions)

[LOGO]    DISTRIBUTIONS AND TAXES
      ---------------------------

          The amount of dividends of net investment income and distributions of
          net realized long and short-term capital gains payable to shareholders
          will be determined separately for the Fund.  Dividends from the net
          investment income of the Fund will be declared and paid monthly. The
          Fund will distribute any net realized long or short-term capital gains
          at least annually.  Your distributions will be reinvested in the Fund
          unless you instruct the Fund otherwise.  There are no fees or sales
          charges on reinvestments.

          In any fiscal year in which the Fund qualifies as a regulated
          investment company and distribute to shareholders all of its net
          investment income and net capital gains, the Fund is relieved of
          federal income tax.

          Generally, all dividends and capital gains are taxable whether they
          are reinvested or received in cash - unless you are exempt from
          taxation or entitled to tax deferral.  Capital gains distributions may
          be taxable at different rates depending on the length of time the Fund
          has held the assets sold.  Early each year, you will be notified as to
          the amount and federal tax status of all distributions paid during the
          prior year.  Distributions may also be subject to state or local
          taxes.  The tax treatment of redemptions from a retirement plan
          account may differ from redemptions from an ordinary shareholder
          account.  If you redeem shares of the Fund or exchange them for shares
          of another Galileo Fund, any gain on the transaction may be subject to
          tax.  You must provide the Fund with a correct taxpayer identification
          number (generally your Social Security Number) and certify that you
          are not subject to backup withholding.  If you fail to do so, the IRS
          can require the Fund to withhold 31% of your taxable distributions and
          redemptions.  Federal law also requires the Fund to withhold 30% or
          the applicable tax treaty rate from dividends paid to nonresident
          alien, non-U.S. partnership and non-U.S. corporation shareholder
          accounts.

          This is a brief summary of some of the tax laws that affect your
          investment in the Fund.  Please see the Statement of Additional
          Information and your tax adviser for further information.

[LOGO]    FINANCIAL HIGHLIGHTS
      --------------------------------------

          The financial highlights table is intended to help you understand the
          Fund's financial performance for the fiscal years indicated.  Certain
          information reflects financial results for a single Fund share.
          "Total return" shows how much your investment in the Institutional
          Class shares of the Fund would have increased (or decreased) during
          each period, assuming you had reinvested all dividends and
          distributions (Class N shares of the Fund commenced operations on
          March 1, 1998).   These figures have been audited by Deloitte & Touche
          LLP, whose report, along with Company's financial statements, are
          included in the annual report, which is available upon request.

INVESTMENT PRACTICES
    
In attempting to achieve its investment objective, a Fund  may utilize, among
others, one or more of the strategies or securities set forth below. The Funds
may, in addition, invest in other instruments (including derivative investments)
or use other investment strategies that are developed or become available in the
future and that are consistent with their objectives and restrictions. Certain
of the Funds, for purposes of calculating certain guidelines, will utilize
the previous month-end capitalization range of various securities indices.    

Strategies Available to All Funds

Money Market Instruments.  All Funds may invest in money market instruments,
although the Bond Funds, Equity Funds and Emerging Markets Income will generally
do so for defensive or temporary purposes only.  These instruments are limited
to:

U.S. Government Securities.  Obligations issued or guaranteed as to principal
- --------------------------                                                   
and interest by the United States or its agencies (such as the Export-Import
Bank of the United States, Federal Housing Administration and Government
National Mortgage Association) or its instrumentalities (such as the Federal
Home Loan Bank), including Treasury bills, notes and bonds;

Bank Obligations.
- ---------------- 

          (All Funds except Money Market)  Obligations including certificates of
deposit, bankers' acceptances, commercial paper (see below) and other debt
obligations of banks subject to regulation by the U.S. Government and having
total assets of $1 billion or more, and instruments secured by such obligations,
not including obligations of foreign branches of domestic banks except as
permitted below.

          (Money Market Fund)  U.S. dollar denominated instruments issued or
guaranteed by the 50 largest bank holding companies in the United States, in
terms of total assets, their subsidiaries and their London branches.  Such bank
obligations may be general obligations of the parent bank holding company or may
be limited to the issuing entity by the terms of the specific obligation or by
government regulation;

          Eurodollar Certificates of Deposit.  (All Funds)  Eurodollar
          ----------------------------------                          
certificates of deposit issued by foreign branches of domestic banks having
total assets of $1 billion or more (investments in Eurodollar certificates may
be affected by changes in currency rates or exchange control regulations, or
changes in governmental administration or economic or monetary policy in the
United States and abroad);

                                       2
<PAGE>
 
          Obligations of Savings Institutions.  (All Funds)  Certificates of
          -----------------------------------                               
deposit of savings banks and savings and loan associations, having total assets
of $1 billion or more (investments in savings institutions above $100,000 in
principal amount are not protected by federal deposit insurance);

          Fully Insured Certificates of Deposit.  (All Funds except Money
          -------------------------------------                          
Market) Certificates of deposit of banks and savings institutions, having total
assets of less than $1 billion, if the principal amount of the obligation is
insured by the Bank Insurance Fund or the Savings Association Insurance Fund
(each of which is administered by the Federal Deposit Insurance Corporation),
limited to $100,000 principal amount per certificate and to 15% or less of the
Fund's total assets in all such obligations and in all illiquid assets, in the
aggregate;

          Commercial Paper.  The Funds may purchase commercial paper rated
          ----------------                                                
within the two highest ratings categories by Standard & Poor's Corporation
("S&P") or Moody's Investors Service, Inc. ("Moody's") or, if not rated, the
security is determined by the Adviser to be of comparable quality.

          World Bank Securities.  (Money Market Fund)  Obligations of the
          ---------------------                                          
International Bank for Reconstruction and Development, also known as the World
Bank (these obligations are supported by subscribed but unpaid commitments of
member countries, and there is no assurance that these commitments will be
undertaken or complied with in the future).

          Money Market Mutual Funds.  (All Funds)  Shares of United States money
          -------------------------                                             
market investment companies not affiliated with the Adviser, subject to
applicable legal restrictions and the Adviser's determination that such
investments are beneficial to the relevant Fund and appropriate in view of such
considerations as yield (taking into account the advisory fees and expenses of
the money market fund), quality and liquidity.

          Other Short-Term Obligations.  (All Funds).  Debt securities that have
          ----------------------------                                          
a remaining maturity of 397 days or less and that have a long-term rating within
the three highest ratings categories by S&P or Moody's.

Repurchase Agreements.  Repurchase agreements, which may be viewed as a type of
secured lending by a Fund, typically involve the acquisition by a Fund of debt
securities from a selling financial institution such as a bank, savings and loan
association or broker-dealer.  The repurchase agreements will provide that the
Fund will sell back to the institution, and that the institution will
repurchase, the underlying security ("collateral") at a specified price and at a
fixed time in the future, usually not more than seven days from the date of
purchase.  The collateral will be maintained in a segregated account and, with
respect to United States repurchase agreements, will be marked to market daily
to ensure that the full value of the collateral, as specified in the repurchase
agreement, does not decrease below the repurchase price plus accrued interest.
If such a decrease occurs, additional collateral will be requested and, when
received, added to the account to maintain full collateralization.  The Fund
will accrue interest from the institution until the date the repurchase occurs.
Although this date is deemed by each Fund to be the maturity date of a
repurchase agreement, the maturities of the collateral securities are not
subject to any limits and

                                       3
<PAGE>
 
may exceed one year. Repurchase agreements maturing in more than seven days will
be considered illiquid for purposes of the restriction on each Fund's investment
in illiquid and restricted securities.

Lending of Portfolio Securities.  Each Fund may, consistent with applicable
regulatory requirements, lend their portfolio securities to brokers, dealers and
other financial institutions, provided such loans are callable at any time by
the Funds (subject to the notice provisions described below), and are at all
times secured by cash, bank letters of credit, other money market instruments
rated A-1, P-1 or the equivalent or securities of the United States Government
(or its agencies or instrumentalities), which are maintained in a segregated
account and that are equal to at least the market value, determined daily, of
the loaned securities.  The advantage of such loans is that the Funds continue
to receive the income on the loaned securities while at the same time earning
interest on the cash amounts deposited as collateral, which will be invested in
short-term obligations.  A Fund will not lend more than 25% of the value of its
total assets.  A loan may be terminated by the borrower on one business day's
notice, or by a Fund on two business day's notice.  If the borrower fails to
deliver the loaned securities within two days after receipt of notice, the Fund
could use the collateral to replace the securities while holding the borrower
liable for any excess of replacement cost over collateral.  As with any
extension of credit, there are risks of delay in recovery and in some cases even
loss of rights in the collateral should the borrower fail financially.  However,
loans of portfolio securities will only be made to firms deemed by the Adviser
to be creditworthy.  Upon termination of the loan, the borrower is required to
return the securities to the Funds.  Any gain or loss in the marketplace during
the loan period would inure to the Fund.

When voting or consent rights which accompany loaned securities pass to the
borrower, the Fund will call the loaned securities, to be delivered within one
day after notice, to permit the Fund to vote the securities if the matters
involved would have a material effect on the Fund's investment in such loaned
securities.  A Fund will pay reasonable finder's, administrative and custodian
fees in connection with a loan of securities.

When-Issued and Delayed Delivery Securities and Forward Commitments.  From time
to time, in the ordinary course of business, any Bond Fund, Equity Fund or
Emerging Markets Income may purchase securities on a when-issued or delayed
delivery basis and may purchase or sell securities on a forward commitment
basis.  When such transactions are negotiated, the price is fixed at the time of
the commitment, but delivery and payment can take place a month or more after
the date of the commitment.  The securities so purchased or sold are subject to
market fluctuation, and no interest or dividends accrue to the purchaser prior
to the settlement date.  While a Fund will only purchase securities on a when-
issued, delayed delivery or forward commitment basis with the intention of
acquiring the securities, the Fund may sell the securities before the settlement
date, if it is deemed advisable.  At the time a Fund makes the commitment to
purchase or sell securities on a when-issued, delayed delivery or forward
commitment basis, the Fund will record the transaction and thereafter reflect
the value, each day, of such security purchased or, if a sale, the proceeds to
be received, in determining its net asset value.  At the time of delivery of the
securities, the value may be more or less than the purchase or sale price.  An
increase in the percentage of a Fund's assets committed to the purchase of
securities on a when-issued or delayed delivery basis may increase the
volatility of the Fund's net asset value.  The Adviser does not believe that any
Fund's net asset value or income will be adversely affected by its purchase of
securities on such basis.

When, As and If Issued Securities.  Emerging Markets Income and the Bond and
Equity Funds may purchase securities on a "when, as and if issued" basis under
which the issuance of the security depends upon the occurrence of a subsequent
event, such as approval of a merger, corporate reorganization, leveraged buyout
or debt restructuring.  The commitment for the purchase of any such security
will not be recognized in the portfolio of the Fund until the Adviser determines
that issuance of the security is probable.  At such time, the Fund will record
the transaction and, in determining its net asset value, will reflect the value
of the security daily.  At such time, the Fund will also establish a segregated
account with its custodian bank in which it will continuously maintain cash or
U.S. Government Securities or other liquid portfolio securities equal in value
to recognized commitments for such securities.  Settlement of the trade will
ordinarily occur within three Business Days of the occurrence of the subsequent
event.  Once a segregated account has been established, if the anticipated event
does not occur and the securities are not issued, the Fund will have lost an
investment opportunity.  Each Fund may purchase securities on such basis without
limit.  An increase in the percentage of the Fund's assets committed to the
purchase of securities on a "when, as and if issued" basis may increase the
volatility of its net asset value.  The Adviser does not believe that the net
asset value of the Fund will be adversely affected by its purchase of securities
on such basis.  Each Fund may also sell securities on a "when, as and if issued"
basis provided that the issuance of the security will result automatically from
the exchange or conversion of a security owned by the Fund at the time of the
sale.

Securities, Mortgage-Backed Securities, Money Market and Latin America Equities

Reverse Repurchase Agreements.  Reverse repurchase agreements involve sales by a
Fund of portfolio securities concurrently with an agreement by the Fund to
repurchase the same securities at a later date at a fixed price.  Generally, the
effect of such a transaction is that the Fund can recover all or most of the
cash invested in the portfolio securities involved during the term of the
reverse repurchase agreement, while it will be able to keep the interest income
associated with those portfolio securities.  Such transactions are only
advantageous if the interest cost to the Fund of the reverse repurchase
transaction is less than the cost of obtaining the cash otherwise.

Strategies Available to Emerging Markets Income, All Bond Funds and Equity Funds
(Except Aggressive Growth Equities and International Equities)

Options.  Emerging Markets Income, the Bond Funds and the Equity Funds (except
Aggressive Growth Equities and International Equities) may purchase and write
(sell) call and put options,  including options listed on U.S. or foreign
securities exchanges or written in over-the-counter transactions ("OTC
Options").

Exchange-listed options are issued by the Options Clearing Corporation ("OCC")
(in the U.S.) or other clearing corporation or exchange which assures that all
transactions in such options are properly executed.  OTC Options are purchased
from or sold (written) to dealers or financial institutions which have entered
into direct agreements with a Fund.  With OTC Options, such variables as
expiration date, exercise price and premium will be agreed upon between a Fund
and the transacting dealer, without the intermediation of a third party such as
the OCC.  If the

                                       5
<PAGE>
 
transacting dealer fails to make or take delivery of the securities or amount of
foreign currency underlying an option it has written, in accordance with the
terms of that option, a Fund would lose the premium paid for the option as well
as any anticipated benefit of the transaction. Each Fund will engage in OTC
Option transactions only with brokers or financial institutions deemed
creditworthy by the Fund's management.

Covered Call Writing.  Emerging Markets Income, the Bond Funds and the Equity
Funds (except Aggressive Growth Equities and International Equities) are
permitted to write covered call options on securities and (for the Equity Funds,
except Aggressive Growth Equities and International Equities and, for the Bond
Funds, Core Fixed Income and Emerging Markets Income) on the U.S. dollar and
foreign currencies.  Generally, a call option is "covered" if a Fund owns, or
has the right to acquire, without additional cash consideration (or for
additional cash consideration held for the Fund by its custodian in a segregated
account) the underlying security (currency) subject to the option except that in
the case of call options on U.S. Treasury bills, a Fund might own U.S. Treasury
bills of a different series from those underlying the call option, but with a
principal amount and value corresponding to the exercise price and a maturity
date no later than that of the security (currency) deliverable under the call
option.  A call option is also covered if a Fund holds a call on the same
security as the underlying security (currency) of the written option, where the
exercise price of the call used for coverage is equal to or less than the
exercise price of the call written or greater than the exercise price of the
call written if the marked to market difference is maintained by a Fund in cash,
U.S. Government Securities or other liquid portfolio securities which a Fund
holds in a segregated account maintained with its custodian.

The writer of an option receives from the purchaser, in return for a call it has
written, a "premium"; i.e., the price of the option.  Receipt of these premiums
may better enable a Fund to earn a higher level of current income than it would
earn from holding the underlying securities (currencies) alone. Moreover, the
premium received will offset a portion of the potential loss incurred by the
Fund if the securities (currencies) underlying the option are ultimately sold
(exchanged) by the Fund at a loss.  Furthermore, a premium received on a call
written on a foreign currency will ameliorate any potential loss of value on the
portfolio security due to a decline in the value of the currency.

However, during the option period, the covered call writer has, in return for
the premium on the option, given up the opportunity for capital appreciation
above the exercise price should the market price of the underlying security (or
the exchange rate of the currency in which it is denominated) increase, but has
retained the risk of loss should the price of the underlying security (or the
exchange rate of the currency in which it is denominated) decline.  The premium
received will fluctuate with varying economic market conditions.  If the market
value of the portfolio securities (or the currencies in which they are
denominated) upon which call options have been written increases, a Fund may
receive a lower total return from the portion of its portfolio upon which calls
have been written than it would have had such calls not been written.

As regards listed options and certain OTC Options, during the option period, a
Fund may be required, at any time, to deliver the underlying security (currency)
against payment of the exercise price on any calls it has written (exercise of
certain listed and OTC Options may be limited to specific expiration dates).
This obligation is terminated upon the expiration of the option period or

                                       6
<PAGE>
 
at such earlier time when the writer effects a closing purchase transaction. A
closing purchase transaction is accomplished by purchasing an option of the same
series as the option previously written. However, once the Fund has been
assigned an exercise notice, the Fund will be unable to effect a closing
purchase transaction.

Closing purchase transactions are ordinarily effected to realize a profit on an
outstanding call option, to prevent an underlying security (currency) from being
called, to permit the sale of an underlying security (or the exchange of the
underlying currency) or to enable a Fund to write another call option on the
underlying security (currency) with either a different exercise price or
expiration date or both.  A Fund may realize a net gain or loss from a closing
purchase transaction depending upon whether the amount of the premium received
on the call option is more or less than the cost of effecting the closing
purchase transaction.  Any loss incurred in a closing purchase transaction may
be wholly or partially offset by unrealized appreciation in the market value of
the underlying security (currency).  Conversely, a gain resulting from a closing
purchase transaction could be offset in whole or in part or exceeded by a
decline in the market value of the underlying security (currency).

If a call option expires unexercised, a Fund realizes a gain in the amount of
the premium on the option less the commission paid.  Such a gain, however, may
be offset by depreciation in the market value of the underlying security
(currency) during the option period.  If a call option is exercised, a Fund
realizes a gain or loss from the sale of the underlying security (currency)
equal to the difference between the purchase price of the underlying security
(currency) and the proceeds of the sale of the security (currency) plus the
premium received on the option less the commission paid.

Covered Put Writing.  As a writer of a covered put option, a Fund incurs an
obligation to buy the security underlying the option from the purchaser of the
put, at the option's exercise price at any time during the option period, at the
purchaser's election (certain listed and OTC put options written by a Fund will
be exercisable by the purchaser only on a specific date).  A put is "covered"
if, at all times, the Fund maintains, in a segregated account maintained on its
behalf at the Fund's custodian, cash, U.S. Government Securities or other liquid
portfolio securities in an amount equal to at least the exercise price of the
option, at all times during the option period.  Similarly, a short put position
could be covered by the Fund by its purchase of a put option on the same
security (currency) as the underlying security of the written option, where the
exercise price of the purchased option is equal to or more than the exercise
price of the put written or less than the exercise price of the put written if
the marked to market difference is maintained by the Fund in cash, U.S.
Government Securities or other liquid portfolio securities which the Fund holds
in a segregated account maintained at its custodian.  In writing puts, a Fund
assumes the risk of loss should the market value of the underlying security
(currency) decline below the exercise price of the option (any loss being
decreased by the receipt of the premium on the option written).  In the case of
listed options, during the option period, the Fund may be required, at any time,
to make payment of the exercise price against delivery of the underlying
security (currency).  The operation of and limitations on covered put options in
other respects are substantially identical to those of call options.

                                       7
<PAGE>
 
The Funds will write put options for three purposes: (a) to receive the income
derived from the premiums paid by purchasers; (b) when the Adviser wishes to
purchase the security (or a security denominated in the currency underlying the
option) underlying the option at a price lower than its current market price, in
which case it will write the covered put at an exercise price reflecting the
lower purchase price sought; and (c) to close out a long put option position.
The potential gain on a covered put option is limited to the premium received on
the option (less the commissions paid on the transaction) while the potential
loss equals the differences between the exercise price of the option and the
current market price of the underlying securities (currencies) when the put is
exercised, offset by the premium received (less the commissions paid on the
transaction).

Purchasing Call and Put Options.  A Fund may purchase a call option in order to
close out a covered call position (see "Covered Call Writing" above), to protect
against an increase in price of a security it anticipates purchasing or, in the
case of a call option on foreign currency, to hedge against an adverse exchange
rate move of the currency in which the security it anticipates purchasing is
denominated vis-a-vis the currency in which the exercise price is denominated.
The purchase of the call option to effect a closing transaction on a call
written over-the-counter may be a listed or an OTC Option.  In either case, the
call purchased is likely to be on the same securities (currencies) and have the
same terms as the written option.  If purchased over-the-counter, the option
would generally be acquired from the dealer or financial institution which
purchased the call written by the Fund.

A Fund may purchase put options on securities or currencies which it holds in
its portfolio to protect itself against a decline in the value of the security
and to close out written put option positions. If the value of the underlying
security or currency were to fall below the exercise price of the put purchased
in an amount greater than the premium paid for the option, the Fund would incur
no additional loss.  In addition, a Fund may sell a put option which it has
previously purchased prior to the sale of the securities (currencies) underlying
such option.  Such a sale would result in a net gain or loss depending whether
the amount received on the sale is more or less than the premium and other
transaction costs paid on the put option which is sold.  Such gain or loss could
be offset in whole or in part by a change in the market value of the underlying
security (currency).  If a put option purchased by a Fund expired without being
sold or exercised, the premium would be lost.

Options on Treasury Bonds and Notes.  Because trading interest in options
written on Treasury bonds and notes tends to center on the most recently
auctioned issues, the exchanges on which such securities trade will not continue
indefinitely to introduce options with new expirations to replace expiring
options on particular issues.  Instead, the expirations introduced at the
commencement of options trading on a particular issue will be allowed to run
their course, with the possible addition of a limited number of new expirations
as the original ones expire.  Options trading on each issue of bonds or notes
will thus be phased out as new options are listed on more recent issues, and
options representing a full range of expirations will not ordinarily be
available for every issue on which options are traded.

Options on Treasury Bills.  Because a deliverable Treasury bill changes from
week to week, writers of Treasury bill calls cannot provide in advance for their
potential exercise settlement

                                       8
<PAGE>
 
obligations by acquiring and holding the underlying security. However, if a Fund
holds a long position in Treasury bills with a principal amount of the
securities deliverable upon exercise of the option, the position may be hedged
from a risk standpoint by the writing of a call option. For so long as the call
option is outstanding, a Fund will hold the Treasury bills in a segregated
account with its custodian, so that they will be treated as being covered.

Options on Foreign Currencies.  The  Equity Funds (except Aggressive Growth
Equities and International Equities), Core Fixed Income and Emerging Markets
Income may purchase and write options on foreign currencies for purposes similar
to those involved with investing in foreign currency forward contracts.  For
example, in order to protect against declines in the dollar value of portfolio
securities which are denominated in a foreign currency, a Fund may purchase put
options on an amount of such foreign currency equivalent to the current value of
the portfolio securities involved.  As a result, the Fund would be enabled to
sell the foreign currency for a fixed amount of U.S. dollars, thereby "locking
in" the dollar value of the portfolio securities (less the amount of the
premiums paid for the options).  Conversely, a Fund may purchase call options on
foreign currencies in which securities it anticipates purchasing are denominated
to secure a set U.S. dollar price for such securities and protect against a
decline in the value of the U.S. dollar against such foreign currency.  Each of
these Funds may also purchase call and put options to close out written option
positions.

Each of these Funds may also write call options on foreign currency to protect
against potential declines in its portfolio securities which are denominated in
foreign currencies.  If the U.S. dollar value of the portfolio securities falls
as a result of a decline in the exchange rate between the foreign currency in
which it is denominated and the U.S. dollar, then a loss to a Fund occasioned by
such value decline would be ameliorated by receipt of the premium on the option
sold.  At the same time, however, the Fund gives up the benefit of any rise in
value of the relevant portfolio securities above the exercise price of the
option and, in fact, only receives a benefit from the writing of the option to
the extent that the value of the portfolio securities falls below the price of
the premium received.  A Fund may also write options to close out long call
option positions.  A put option on a foreign currency would be written by the
Fund for the same reason it would purchase a call option, namely, to hedge
against an increase in the U.S. dollar value of a foreign security which a Fund
anticipates purchasing.  Here, the receipt of the premium would offset, to the
extent of the size of the premium, any increased cost to a Fund resulting from
an increase in the U.S. dollar value of the foreign security.  However, a Fund
could not benefit from any decline in the cost of the foreign security which is
greater than the price of the premium received.  A Fund may also write options
to close out long put and call option positions.

The markets in foreign currency options are relatively new and a Fund's ability
to establish and close out positions on such options is subject to the
maintenance of a liquid secondary market.  Although the Funds will not purchase
or write such options unless and until, in the opinion of the Adviser, the
market for them has developed sufficiently to ensure that the risks in
connection with such options are not greater than the risks in connection with
the underlying currency, there can be no assurance that a liquid secondary
market will exist for a particular option at any specific time.  In addition,
options on foreign currencies are affected by all of those factors which
influence foreign exchange rates and investments generally.

                                       9
<PAGE>
 
The value of a foreign currency option depends upon the value of the underlying
currency relative to the U.S. dollar.  As a result, the price of the option
position may vary with changes in the value of either or both currencies and
have no relationship to the investment merits of a foreign security, including
foreign securities held in a "hedged" investment portfolio.  Because foreign
currency transactions occurring in the interbank market involve substantially
larger amounts than those that may be involved in the use of foreign currency
options, investors may be disadvantaged by having to deal in an odd lot market
(generally consisting of transactions of less than $1 million) for the
underlying foreign currencies at prices that are less favorable than for round
lots.

There is no systematic reporting of last sale information for foreign currencies
or any regulatory requirement that quotations available through dealers or other
market sources be firm or revised on a timely basis.  Quotation information
available is generally representative of very large transactions in the
interbank market and thus may not reflect relatively smaller transactions (i.e.,
less than $ l million) where rates may be less favorable. The interbank market
in foreign currencies is a global, around-the-clock market. To the extent that
the U.S. options markets are closed while the markets for the underlying
currencies remain open, significant price and rate movements may take place in
the underlying markets that are not reflected in the options market.

Strategies Available to Emerging Markets Income, All Bond Funds and Equity Funds
(Except Large Cap Growth, Aggressive Growth Equities, Small Cap Value, Value
Opportunities and International Equities)

Futures Contracts.  Emerging Markets Income, the Bond Funds and the Equity Funds
(except Large Cap Growth, Aggressive Growth Equities, Small Cap Value, Value
Opportunities and International Equities) may purchase and sell interest rate,
currency, and index futures contracts ("futures contracts"), on securities
eligible for purchase by the Fund. Subject to certain limitations, a Fund may
enter into futures contracts or options on such contracts to attempt to protect
against possible changes in the market value of securities held in or to be
purchased by the Fund resulting from interest rate or market fluctuations, to
protect the Fund's unrealized gains in the value of its portfolio securities, to
facilitate the sale of such securities for investment purposes, to manage its
effective maturity or duration, or to establish a position in the derivatives
markets as a temporary substitute for purchasing or selling particular
securities.

To the extent futures positions constitute "bona fide hedge" positions as
defined by the rules and regulations of the Commodity Futures Trading Commission
("CFTC"), there is no overall limitation on the percentage of a Fund's assets
which may be committed to futures contracts and options or futures contracts,
provided the aggregate value of such positions does not exceed the value of such
Fund's portfolio securities.  With respect to futures positions that are not
"bona fide hedge" positions, no Fund may enter into futures contracts or related
options if, immediately thereafter, the amount of initial margin and premiums
for unexpired futures contracts and options on futures contracts exceeds 5% of
the Fund's liquidation value, after taking into account unrealized profits and
losses on such futures contracts, provided, however, that in the case of an
option that is in-the-money (the exercise price of the call (put) option is less
(more) than the market price of the underlying security) at the time of
purchase, the in-the-money amount may be excluded in calculating the 5%.

                                       10

A Fund may purchase or sell interest rate futures for the purpose of hedging
some or all of the value of its portfolio securities against changes in
prevailing interest rates or to manage its duration or effective maturity.  If
the Adviser anticipates that interest rates may rise and, concomitantly, the
price of certain of its portfolio securities may fall, the Fund may sell futures
contracts.  If declining interest rates are anticipated, the Fund may purchase
futures contracts to protect against a potential increase in the price of
securities the Fund intends to purchase.  Subsequently, appropriate securities
may be purchased by the Fund in an orderly fashion; as securities are purchased,
corresponding futures positions would be terminated by offsetting sales of
contracts.  A Fund may purchase or sell futures on various currencies in which
its portfolio securities are denominated for the purpose of hedging against
anticipated changes in currency exchange rates.  A Fund will enter into currency
futures contracts to "lock in" the value of a security purchased or sold in a
given currency vis-a-vis a different currency or to hedge against an adverse
currency exchange rate movement of a portfolio security's denominated currency
vis-a-vis a different currency.  Foreign currency futures contracts would be
entered into for the same reason and under the same circumstances as foreign
currency forward contracts.  The Adviser will assess such factors as cost
spreads, liquidity and transaction costs in determining whether to utilize
futures contracts or forward contracts in its foreign currency transactions and
hedging strategy.

Initial margin in futures transactions is different from margin in securities
transactions in that initial margin does not involve the borrowing of funds by a
broker's client but is, rather, a good faith deposit on the futures contract
which will be returned to a Fund upon the proper termination of the futures
contract.  The margin deposits are marked to market daily and the Fund may be
required to make subsequent deposits of cash or U.S. Government Securities
called "variation margin", with the Fund's futures contract clearing broker,
which are reflective of price fluctuations in the futures contract.  Initial
margin requirements are established by the exchanges on which futures contracts
trade and may, from time to time, change. In addition, brokers may establish
margin deposit requirements in excess of those required by the exchanges.

At any time prior to expiration of a futures contract, a Fund may elect to close
the position by taking an opposite position which will operate to terminate the
Fund's position in the futures contract.  A final determination of any variation
margin is then made, additional cash is required to be paid by or released to
the Fund and the Fund realizes a loss or gain.

Although many futures contracts call for actual commitment or acceptance of
securities, the contracts usually are closed out before the settlement date
without making or taking delivery.  A short futures position is usually closed
out by purchasing futures contracts for the same aggregate amount of the
underlying instruments and with the same delivery date.  If the sale price
exceeds the offsetting purchase price, the seller would be paid the difference
and realize a gain.  If the offsetting purchase price exceeds the sales price,
the seller would pay the difference and would realize a loss.  Similarly, a long
futures position in usually closed out by effecting a futures contract sale for
the same aggregate amount of the specific type of security (currency) and the
same delivery date.  If the offsetting sales price exceeds the purchase price,
the purchaser would realize a gain, whereas if the purchase price exceeds the
offsetting sale price, the purchaser would realize a loss.  There is no
assurance that a Fund will be able to enter into a closing transactions.

Options on Futures Contracts.  Emerging Markets Income, the Bond Funds and the
Equity Funds (except Large Cap Growth, Aggressive Growth Equities, Small Cap
Value, Value Opportunities and International Equities) may also purchase and
write call and put options on futures contracts which are traded on an exchange
and enter into closing transactions with respect to such options to terminate an
existing position.  An option on a futures contract gives the purchaser the
right (in return for the premium paid) to assume a position in a futures
contract (a long position if the option is a call and a short position if the
option is a put) at a specified exercise price at any time during the term of
the option.

Funds will purchase and write options on futures contracts for identical
purposes to those set forth above for the purchase of a futures contract
(purchase of a call option or sale of a put option) and the sale of a futures
contract (purchase of a put option or sale of a call option), or to close out a
long or short position in futures contracts.  If, for example, a Fund wished to
protect against an increase in interest rates and the resulting negative impact
on the value of a portion of its fixed-income portfolio, it might write a call
option on an interest rate futures contract, the underlying security of which
correlates with the portion of the portfolio the Fund seeks to hedge.  Any
premiums received in the writing of options on futures contracts may, of course,
provide a further hedge against losses resulting from price declines in portions
of a Fund's portfolio.

Strategies Available to High Yield Bond and the Equity Funds (except
International Equities)

Convertible Securities.  Convertible securities include bonds, debentures,
notes, preferred stock or other securities that may be converted into or
exchanged for common stock or other equity securities of the same or a different
issuer.  The Funds will invest primarily in convertible securities that are
rated at least B- by S&P or B3 by Moody's or, if not rated, determined to be of
comparable quality by the Adviser except Emerging Markets Income which can
invest a substantial portion of its assets in convertible securities rated lower
than B- by S&P or B3 by Moody's or, if not rated, determined to be of comparable
quality by the Adviser.  Convertible securities provide a conversion right for a
particular period of time at a specified price or formula.  A convertible
security entitles the holder to receive interest paid or accrued on debt or the
dividend paid on preferred stock until the convertible security matures or is
redeemed, converted or exchanged.  Before conversion, convertible securities
have characteristics similar to nonconvertible debt securities in that they
ordinarily provide a stable stream of income with generally higher yields than
those of common stocks of the same or similar issuers.  Therefore, they
generally entail less risk than the corporation's common stock, although the
extent to which such risk is reduced depends in large measure upon the proximity
of its price to its value as a nonconvertible fixed income security.

The value of a convertible security is a function of its "investment value"
(determined by its yield in comparison with the yields of other securities of
comparable maturity and quality that do not have a conversion privilege), and
its "conversion value" (the security's worth, at market value, if converted into
the underlying common stock).  The investment value of a convertible security is
influenced by changes in interest rates, with investment value declining as
interest rates increase and increasing as interest rates decline.  The credit
standing of the issuer and other factors may also have an effect on the
convertible security's investment value.  The conversion value of a convertible
security is determined by the market price of the underlying common stock.  If
the

                                       12
<PAGE>
 
conversion value is low relative to the investment value, the price of the
convertible security is governed principally by its investment value.  To the
extent the market price of the underlying common stock approaches or exceeds the
conversion price, the price of the convertible security will be increasingly
influenced by its conversion value.  In addition, a convertible security
generally will sell at a premium over its conversion value determined by the
extent to which investors place value on the right to acquire the underlying
common stock while holding a fixed income security.

Strategies Available to Core Fixed Income, Asia Pacific Equities, Emerging
Markets Equities, Emerging Markets Income, European Equities and Latin America
Equities

Sovereign Debt Obligations.  The Core Fixed Income, Asia Pacific Equities,
Emerging Markets Equities, Emerging Markets Income, European Equities and Latin
America Equities may invest in Sovereign Debt of emerging market countries.
Political conditions, in terms of a country or agency's willingness to meet the
terms of its debt obligations, are of considerable significance.  Investors
should be aware that the Sovereign Debt instruments in which these Funds may
invest involve great risk and are deemed to be the equivalent in terms of
quality to securities rated below investment grade by Moody's and S&P.

Sovereign Debt generally offers high yields, reflecting not only perceived
credit risk, but also the need to compete with other local investments in
domestic financial markets.  Mexico and certain other emerging market countries
are among the largest debtors to commercial banks and foreign governments.  A
foreign debtor's willingness or ability to repay principal and interest due in a
timely manner may be affected by, among other factors, its cash flow situation,
the extent of its foreign reserves, the availability of sufficient foreign
exchange on the date a payment is due, the relative size of the debt service
burden to the economy as a whole, the foreign debtor's policy towards the
International Monetary Fund and the political constraints to which a sovereign
debtor may be subject.  Sovereign debtors may default on their Sovereign Debt.
Sovereign debtors may also be dependent on expected disbursements from foreign
governments, multilateral agencies and others abroad to reduce principal and
interest arrearages on their debt.  The commitment on the part of these
governments, agencies and others to make such disbursements may be conditioned
on a sovereign debtor's implementation of economic reforms and/or economic
performance and the timely service of such debtor's obligations.  Failure to
implement such reforms, achieve such levels of economic performance or repay
principal or interest when due may result in the cancellation of such third
parties' commitments to lend funds to the sovereign debtor, which may further
impair such debtor's ability or willingness to service its debts.

In recent years, some of the emerging market countries in which the Funds expect
to invest have encountered difficulties in servicing their Sovereign Debt.  Some
of these countries have withheld payments of interest and/or principal of
Sovereign Debt.  These difficulties have also led to agreements to restructure
external debt obligations; in particular, commercial bank loans, typically by
rescheduling principal payments, reducing interest rates and extended new
credits to finance interest payments on existing debt.  In the future, holders
of Sovereign Debt may be requested to participate in similar reschedulings to
such debt.

                                       13
<PAGE>
 
The ability or willingness of the governments of Mexico and other emerging
market countries to make timely payments on their Sovereign Debt is likely to be
influenced strongly by a country's balance of trade and its access to trade and
other international credits.  A country whose exports are concentrated in a few
commodities could be vulnerable to a decline in the international prices of one
or more of such commodities.  Increased protectionism on the part of a country's
trading partners could also adversely affect its exports.  Such events could
extinguish a country's trade account surplus, if any.  To the extent that a
country receives payment for its exports in currencies other than hard
currencies, its ability to make hard currency payments could be affected.

The occurrence of political, social and diplomatic changes in one or more of the
countries issuing Sovereign Debt could adversely affect the Funds' investments.
The countries issuing such instruments are faced with social and political
issues and some of them have experienced high rates of inflation in recent years
and have extensive internal debt.  Among other effects, high inflation and
internal debt service requirements may adversely affect the cost and
availability of future domestic sovereign borrowing to finance governmental
programs, and may have other adverse social, political and economic
consequences.  Political changes or a deterioration of a country's domestic
economy or balance of trade may affect the willingness of countries to service
their Sovereign Debt.  There can be no assurance that adverse political changes
will not cause the Funds to suffer a loss of interest or principal on any of its
holdings.

As a result of all of the foregoing, a government obligor may default on its
obligations.  If such an event occurs, a Fund may have limited legal recourse
against the issuer and/or guarantor.  Remedies must, in some cases, be pursued
in the courts of the defaulting party itself, and the ability of the holder of
foreign government debt securities to obtain recourse may be subject to the
political climate in the relevant country.  Bankruptcy, moratorium and other
similar laws applicable to issuers of Sovereign Debt Obligations may be
substantially different from those applicable to issuers of private debt
obligations.  In addition, no assurance can be given that the holders of
commercial bank debt will not contest payments to the holders of other foreign
government debt obligations in the event of default under their commercial bank
loan agreements.

Periods of economic uncertainty may result in the volatility of market prices of
Sovereign Debt and in turn, the Funds' net asset value, to a greater extent than
the volatility inherent in domestic securities.  The value of Sovereign Debt
will likely vary inversely with changes in prevailing interest rates, which are
subject to considerable variance in the international market.

Strategies Available to Core Fixed Income, Total Return Mortgage-Backed
Securities and Mortgage-Backed Securities

Guaranteed Mortgage Pass-Through Securities.  Core Fixed Income, Total Return
Mortgage-Backed Securities and Mortgage-Backed Securities may invest in mortgage
pass-through securities representing participation interests in pools of
residential mortgage loans purchased from individual lenders by a Federal Agency
or originated by private lenders and guaranteed, to the extent provided in such
securities, by a Federal Agency.  Such securities, which are ownership interests
in the underlying mortgage loans, differ from conventional debt securities,
which provide for periodic payment of interest in fixed amounts (usually
semiannually) and principal payments at maturity or on specified call dates.
Mortgage pass-through securities provide for monthly payments (not necessarily
in fixed amounts) that are a "pass-through" of the monthly interest and
principal payments (including any prepayments) made by the individual borrowers
on the pooled mortgage loans, net of any fees paid to the guarantor of such
securities and the servicer of the underlying mortgage loans.

The guaranteed mortgage pass-through securities in which the Funds may invest
include those issued or guaranteed by GNMA, FNMA and FHLMC.  GNMA certificates
are direct obligations of the U.S. Government and, as such, are backed by the
"full faith and credit" of the United States.  FNMA is a federally chartered,
privately owned corporation and FHLMC is a corporate instrumentality of the
United States.  FNMA and FHLMC certificates are not backed by the full faith and
credit of the United States but the issuing agency or instrumentality has the
right to borrow, to meet its obligations, from an existing line of credit with
the U.S. Treasury.  The U.S. Treasury has no legal obligation to provide such
line of credit and may choose not to do so.

Certificates for these types of mortgage-backed securities evidence an interest
in a specific pool of mortgages.  These certificates are, in most cases,
"modified pass-through" instruments, wherein the issuing agency guarantees the
payment of principal and interest on mortgages underlying the certificates,
whether or not such amounts are collected by the issuer on the underlying
mortgages.

Collateralized Mortgage Obligations and Multiclass Pass-Through Securities.
CMOs are debt obligations collateralized by mortgage loans or mortgage pass-
through securities.  Typically, CMOs are collateralized by GNMA, FNMA or FHLMC
certificates, but also may be collateralized by whole loans or private mortgage
pass-through securities (such collateral is collectively hereinafter referred to
as "Mortgage Assets").  Multiclass pass-through securities are equity interests
in a trust composed of Mortgage Assets.  Payments of principal of and interest
on the Mortgage Assets, and any reinvestment income thereon, provide the funds
to pay debt service on the CMOs or make scheduled distributions on the
multiclass pass-through securities.  CMOs may be issued by Federal Agencies, or
by private originators of, or investors in, mortgage loans, including savings
and loan associations, mortgage banks, commercial banks, investment banks and
special purpose subsidiaries of the foregoing.  The issuer of a series of CMOs
may elect to be treated as a Real Estate Mortgage Investment Conduit ("REMIC").
REMICs include governmental and/or private entities that issue a fixed pool of
mortgages secured by an interest in real property.  REMICs are similar to CMOs
in that they issue multiple classes of securities, but unlike CMOs, which are
required to be structured as debt securities, REMICs may be structured as
indirect ownership

                                       15
<PAGE>
 
interests in the underlying assets of the REMICs themselves. However, there are
no effects on a Fund from investing in CMOs issued by entities that have elected
to be treated as REMICs, and all future references to CMOs shall also be deemed
to include REMIC.

In a CMO, a series of bonds or certificates is issued in multiple classes.  Each
class of CMOs, often referred to as a "tranche," is issued at a specific fixed
or floating coupon rate and has a stated maturity or final distribution date.
Principal prepayments on the Mortgage Assets may cause the CMOs to be retired
substantially earlier than their stated maturities or final distribution dates.
Interest is paid or accrues on all classes of the CMOs on a monthly, quarterly
or semiannual basis.  Certain CMOs may have variable or floating interest rates
and others may be Stripped Mortgage Securities.

The principal of and interest on the Mortgage Assets may be allocated among the
several classes of a CMO series in a number of different ways.  Generally, the
purpose of the allocation of the cash flow of a CMO to the various classes is to
obtain a more predictable cash flow to certain of the individual tranches than
exists with the underlying collateral of the CMO.  As a general rule, the more
predictable the cash flow is on a CMO tranche, the lower the anticipated yield
will be on that tranche at the time of issuance relative to prevailing market
yields on other mortgage-backed securities.  As part of the process of creating
more predictable cash flows on most of the tranches in a series of CMOs, one or
more tranches generally must be created that absorb most of the volatility in
the cash flows on the underlying mortgage loans.  The yields on these tranches
are generally higher than prevailing market yields on mortgage-backed securities
with similar maturities.  As a result of the uncertainty of the cash flows of
these tranches, the market prices of and yield on these tranches generally are
more volatile.  The Funds will not invest in CMO and REMIC residuals.

Private Mortgage Pass-Through Securities.  Private mortgage pass-through
securities are structured similarly to the GNMA, FNMA and FHLMC mortgage pass-
through securities and are issued by United States and foreign private issuers
such as originators of and investors in mortgage loans, including savings and
loan associations, mortgage banks, commercial banks, investment banks and
special purpose subsidiaries of the foregoing.  These securities usually are
backed by a pool of conventional fixed rate or adjustable rate mortgage loans.
Since private mortgage pass-through securities typically are not guaranteed by
an entity having the credit status of GNMA, FNMA and FHLMC, such securities
generally are structured with one or more types of credit enhancement.

Mortgage-backed securities are often backed by a pool of assets representing the
obligations of a number of different parties.  To lessen the effect of failures
by obligors on underlying assets to make payments, those securities may contain
elements of credit support, which fall into two categories:  (i) liquidity
protection and (ii) protection against losses resulting from ultimate default by
an obligor on the underlying assets.  Liquidity protection refers to the
provision of advances, generally by the entity administering the pool of assets,
to ensure that the receipt of payments on the underlying pool occurs in a timely
fashion.  Protection against losses resulting from default ensures ultimate
payment of the obligations on at least a portion of the assets in the pool.
This protection may be provided through guarantees, insurance policies or
letters of credit obtained by the issuer or sponsor from third parties, through
various means of structuring the transaction or

                                       16
<PAGE>
 
through a combination of such approaches. The degree of credit support provided
for each issue is generally based on historical information respecting the level
of credit risk associated with the underlying assets. Delinquencies or losses in
excess of those anticipated could adversely affect the return on an investment
in a security. The Funds will not pay any fees for credit support, although the
existence of credit support may increase the price of a security.

Stripped Mortgage Securities.  Stripped Mortgage Securities may be issued by
Federal Agencies, or by private originators of, or investors in, mortgage loans,
including savings and loan associations, mortgage banks, commercial banks,
investment banks and special purpose subsidiaries of the foregoing.  Stripped
Mortgage Securities not issued by Federal Agencies will be treated by the Funds
as illiquid securities so long as the staff of the Securities and Exchange
Commission maintains its position that such securities are illiquid.

Stripped Mortgage Securities usually are structured with two classes that
receive different proportions of the interest and principal distribution on a
pool of mortgage assets.  A common type of Stripped Mortgage Security will have
one class receiving some of the interest and most of the principal from the
mortgage assets, while the other class will receive most of the interest and the
remainder of the principal.  In the most extreme case, one class will receive
all of the interest (the interest-only or "IO" class), while the other class
will receive all of the principal (the principal-only or "PO" class).  PO
classes generate income through the accretion of the deep discount at which such
securities are purchased, and, while PO classes do not receive periodic payments
of interest, they receive monthly payments associated with scheduled
amortization and principal prepayment from the mortgage assets underlying the PO
class.  The yield to maturity on an IO class is extremely sensitive to the rate
of principal payments (including prepayments) on the related underlying mortgage
assets, and a rapid rate of principal payments may have a material adverse
effect on such security's yield to maturity.  If the underlying mortgage assets
experience greater than anticipated prepayments of principal, the Fund may fail
to fully recoup its initial investment in these securities.

A Fund may purchase Stripped Mortgage Securities for income, or for hedging
purposes to protect the Fund's portfolio against interest rate fluctuations.
For example, since an IO class will tend to increase in value as interest rates
rise, it may be utilized to hedge against a decrease in value of other fixed-
income securities in a rising interest rate environment.

Mortgage Dollar Rolls.  The Funds may enter into mortgage dollar rolls with a
bank or a broker-dealer.  A mortgage dollar roll is a transaction in which a
Fund sells mortgage-related securities for immediate settlement and
simultaneously purchases the same type of securities for forward settlement at a
discount.  While the Fund begins accruing interest on the newly purchased
securities from the purchase or trade date, it is able to invest the proceeds
from the sale of its previously owned securities, which will be used to pay for
the new securities, in money market investments until the future settlement
date.  The use of mortgage dollar rolls is a speculative technique involving
leverage, and is considered to be a form of borrowing by the Fund.

Asset-Backed Securities.  Asset-backed securities have structural
characteristics similar to mortgage-backed securities but have underlying assets
that are not mortgage loans or interests in

                                       17
<PAGE>
 
mortgage loans. Various types of assets, primarily automobile and credit card
receivables, are securitized in pass-through structures similar to mortgage 
pass-through structures. In general, the collateral supporting asset-backed
securities is of shorter maturity than mortgage loans and is likely to
experience substantial prepayments. As with mortgage-related securities, asset-
backed securities are often backed by a pool of assets representing the
obligations of a number of different parties and use similar credit enhancement
techniques. The cash flow generated by the underlying assets is applied to make
required payments on the securities and to pay related administrative expenses.
The amount of residual cash flow resulting from a particular issue of asset-
backed or mortgage-backed securities depends on, among other things, the
characteristics of the underlying assets, the coupon rates on the securities,
prevailing interest rates, the amount of administrative expenses and the actual
prepayment experience on the underlying assets. Core Fixed Income, Total Return
Mortgage-Backed Securities and Mortgage-Backed Securities may each invest in any
such instruments or variations as may be developed, to the extent consistent
with its investment objectives and policies and applicable regulatory
requirements.

Inverse Floaters.  Inverse floaters constitute a class of CMOs with a coupon
rate that moves inversely to a designated index, such as LIBOR or COFI.  Inverse
floaters have coupon rates that typically change at a multiple of the changes of
the relevant index rate.  Any rise in the index rate (as a consequence of an
increase in interest rates) causes a drop in the coupon rate on an inverse
floater while any drop in the index rate causes an increase in the coupon rate
of an inverse floater.  In some circumstances, the coupon on an inverse floater
could decrease to zero.  In addition, like most other fixed-income securities,
the value of inverse floaters will decrease as interest rates increase and their
average lives will extend.  Inverse floaters exhibit greater price volatility
than the majority of mortgage-backed securities.  In addition, some inverse
floaters display extreme sensitivity to changes in prepayments.  As a result,
the yield to maturity of an inverse floater is sensitive not only to changes in
interest rates but also to changes in prepayment rates on the related underlying
mortgage assets.  As described above, inverse floaters may be used alone or in
tandem with interest-only stripped mortgage instruments.  The Adviser believes
that, notwithstanding the fact that inverse floaters exhibit price volatility,
the use of inverse floaters as a component of the Fund's overall portfolio, in
light of the Fund's anticipated portfolio composition in the aggregate, is
compatible with the Fund's objective.

Growth Equities and International Equities), Core Fixed Income and Emerging
Markets Income

Forward Currency Transactions.  The Equity Funds (except Earnings Momentum,
Aggressive Growth Equities and International Equities), Core Fixed Income and
Emerging Markets Income may enter into forward currency transactions.  A foreign
currency forward contract involves an obligation to purchase or sell a specific
currency at an agreed future date, at a price set at the time of the contract.
These contracts are traded in the interbank market conducted directly between
currency traders.  A Fund may enter into foreign currency forward contracts in
order to protect against the risk that the U.S. dollar value of the Fund's
dividends, interest and net realized capital gains in local currency will
decline to the extent of any devaluation of the currency during the intervals
between (a) (i) the time the Fund becomes entitled to receive or receives
dividends, interest and realized gains or (ii) the time an investor gives notice
of a requested redemption of a certain amount and (b) the time such amount(s)
are converted into U.S. dollars for remittance out of the particular country or
countries.

At the maturity of a forward contract, a Fund may either accept or make delivery
of the currency specified in the contract or, prior to maturity, enter into a
closing purchase transaction involving the purchase or sale of an offsetting
contract.  Closing purchase transactions with respect to forward contracts are
usually effected with the currency trader who is a party to the original forward
contract.

The cost to a Fund of engaging in forward currency transactions may vary with
factors such as the length of the contract period and the market conditions then
prevailing.  Because forward currency transactions are usually conducted on a
principal basis, no fees or commissions are involved, although the price charged
in the transaction includes a dealer's markup.  The use of forward currency
contracts does not eliminate fluctuations in the underlying prices of the
securities, but it does establish a rate of exchange that can be achieved in the
future.  In addition, although forward currency contracts limit the risk of loss
due to a devaluation of the foreign currency in relation to the U.S. dollar,
they also limit any potential gain if that foreign currency appreciates with
respect to the U.S. dollar.

Short Sales Against the Box.  The Convertible Securities, Large Cap Growth and
Large Cap Value Funds may from time to time make short sales of securities it
owns or has the right to acquire through conversion or exchange of other
securities it owns.  A short sale is "against the box" to the extent that a Fund
contemporaneously owns or has the right to obtain at no added cost securities
identical to those sold short.  In a short sale, a Fund does not immediately
deliver the securities sold and does not receive the proceeds from the sale.
The Fund is said to have a short position in the securities sold until it
delivers the securities sold, at which time it receives the proceeds of the
sale.  When a short sale transaction is closed out by delivery of the
securities, any gain or loss on the transaction is taxable as a short term
capital gain or loss.

To secure its obligation to deliver the securities sold short, a Fund will
deposit in a separate escrow account with its custodian an equal amount of the
securities sold short or securities convertible into

                                       19
<PAGE>
 
or exchangeable for such securities. The Fund may close out a short position by
purchasing and delivering an equal amount of the securities sold short, rather
than by delivering securities already held by the Fund, because the Fund may
want to continue to receive interest and dividend payments on securities in its
portfolio that are convertible into the securities sold short.

A Fund may make a short sale in order to hedge against market risks when the
Adviser believes that the price of a security may decline, causing a decline in
the value of a security owned by the Fund or a security convertible into or
exchangeable for such security.  However, to the extent that in a generally
rising market the Fund maintains short positions in securities rising with the
market, the net asset value of the Fund would be expected to increase to a
lesser extent than the net asset value of an investment company that does not
engage in short sales.  A Fund may also make a short sale when it does not want
to sell the security it owns, because, among other reasons, it wishes to defer
recognition of gain or loss for Federal income tax purposes.  In such case, any
future losses in the Fund's long position should be reduced by a gain in the
short position.  The extent to which such gains or losses are reduced will
depend upon the amount of the security sold short relative to the amount the
Fund owns, either directly or indirectly, and, in the case where the Fund owns
convertible securities, changes in the investment value or conversion premiums.
Additionally, a Fund may use short sales when it is determined that a
convertible security can be bought at a small conversion premium and has a yield
advantage relative to the underlying common stock sold short.  The potential
risk in this strategy is the possible loss of any premium over conversion value
in the convertible security at the time of purchase.  The purpose of this
strategy is to produce income from the yield advantage and to provide the
potential for a gain should the conversion premium increase.

Investment in Other Investment Vehicles.  Investment in other investment
companies or similar investment vehicles may be the sole or most practical means
by which a Fund can participate in certain Latin American, Asian and other
emerging securities markets or invest in particular industries within those
markets.  Some of these investment vehicles may be closed-end investment
companies which may trade at a discount from their net asset value.  Such
investments may involve the payment of substantial premiums above the value of
such issuers' portfolio securities, and are subject to limitations under the
1940 Act (see below) and market availability.  There can be no assurance that
vehicles or funds for investing in certain Latin American, Asian and other
Emerging Markets countries will be available for investment, particularly in the
early stages of the Fund's operations.  In addition, special tax considerations
may apply.  The Funds do not intend to invest in such vehicles or funds unless,
in the judgment of the Adviser, the potential benefits of such investment
justify the payment of any applicable premium or sales charges.  As a
shareholder in an investment company, the Funds would bear their ratable share
of that investment company's expenses, including its advisory and administration
fees.  At the same time the Fund would continue to pay their own management and
advisory fees and other expenses.  Under the 1940 Act, the Funds generally may
invest up to 10% of its total assets in the aggregate in shares of other
investment companies and up to 5% of its total assets in any one investment
company, as long as that investment does not represent more than 3% of the
voting stock of the acquired investment company at the time such shares are
purchased.

Investment for the Purpose of Acquiring Control.  The Asia Pacific Equities,
Latin America Equities and Emerging Markets Equities Funds may acquire the
securities of wholly-owned subsidiaries in order to facilitate investing in the
securities of certain foreign issuers.  The tax laws of certain countries impose
a capital gains tax on profits derived from securities dispositions.  Certain of
these countries have double taxation treaties whereby residents of one country
are exempt from taxation on their investments in the securities of issuers in
another country.  The Funds intend to establish wholly-owned subsidiaries in
certain foreign countries to take advantage of these double taxation treaties in
order to avoid the imposition of various taxes, including capital gains

RISK CONSIDERATIONS

The following risk considerations relate to investment practices undertaken by
some or all of the Funds.  Generally, since shares of a Fund represent an
investment in securities with fluctuating market prices, shareholders should
understand that the value of their Fund shares will vary as the value of each
Fund's portfolio securities increases or decreases.  Therefore, the value of an
investment in a Fund could go down as well as up.  There is no guarantee of
successful performance, that a Fund's objective can be achieved or that an
investment in a Fund will achieve a positive return. Each Fund should be
considered as a means of diversifying an investment portfolio and is not in
itself a balanced investment program.

Prospective investors should consider the following risks.

General

Various market risks can affect the price or liquidity of an issuer's
securities.  Adverse events occurring with respect to an issuer's performance or
financial position can depress the value of the issuer's securities.  The
liquidity in a market for a particular security will affect its value and may be
affected by factors relating to the issuer, as well as the depth of the market
for that security.  Other market risks that can affect value include a market's
current attitudes about type of security, market reactions to political or
economic events, and tax and regulatory effects (including lack of adequate
regulations for a market or particular type of instrument).  Market restrictions
on trading volume can also affect price and liquidity.
    
Certain risks exist because of the composition and investment horizon of a
particular portfolio of securities.  Prices of many securities tend to be more
volatile in the short-term and lack of diversification in a portfolio can also
increase volatility. Certain Galileo Funds are not diversified. Non-diversified
Funds are not subject to certain regulatory limits, including limits on the size
of their positions in individual issuers.  To the extent such funds exceed these
limits, they will be more exposed to risks of particular issuers than a
diversified fund.  Such funds will, however, comply with the diversification
requirements of Subchapter M of the Internal Revenue Code of 1986, as amended.
A security that is leveraged, whether explicitly or implicitly, will also tend
to be more volatile in that both gains and losses are intensified by the
magnifying     

                                       21
<PAGE>
 
effects of leverage. Certain instruments (such as inverse floaters) behave
similarly to leveraged instruments. Generally, such securities contain formulas
requiring recalculation of their interest rates in a manner that multiplies the
change in a market rate.

Repurchase Agreements

In the event of a default or bankruptcy by a selling financial institution under
a repurchase agreement, a Fund will seek to sell the underlying security serving
as collateral.  However, this could involve certain costs or delays, and, to the
extent that proceeds from any sale were less than the repurchase price, the Fund
could suffer a loss.  Each Fund follows procedures designed to minimize the
risks associated with repurchase agreements, including effecting repurchase
transactions only with large, well-capitalized and well-established financial
institutions and specifying the required value of the collateral underlying the
agreement.

Reverse Repurchase Agreements and Mortgage Dollar Rolls

Reverse repurchase agreements and mortgage dollar rolls involve the risk that
the market value of the securities a Fund is obligated to repurchase under the
agreement may decline below the repurchase price.  In the event the buyer of
securities under a reverse repurchase agreement or mortgage dollar roll files
for bankruptcy or becomes insolvent, the Fund's use of proceeds of the agreement
may be restricted pending a determination by the other party, or its trustee or
receiver, whether to enforce the Fund's obligation to repurchase the securities.
Reverse repurchase agreements and mortgage dollar rolls are speculative
techniques involving leverage, and are considered borrowings by the Fund.  Under
the requirements of the 1940 Act, the Fund is required to maintain an asset
coverage (including the proceeds of the borrowings) of at least 300% of all
borrowings.  None of the Funds authorized to utilize these instruments expects
to engage in reverse repurchase agreements or mortgage dollar rolls (together
with other borrowings of the Fund) with respect to greater than 30% of the
Fund's total assets.

Fixed Income Securities

Fixed Income securities are subject to various risks.  The two primary (but not
exclusive) risks affecting fixed income instruments are "credit risk" and
"interest rate risk."  These risks can affect a security's price volatility to
varying degrees, depending upon the nature of the instrument.  In addition, the
depth and liquidity of the market for an individual or class of fixed income
security can also affect its price and, hence, the market value of a Fund.

"Credit risk" refers to the likelihood that an issuer will default in the
payment of principal and/or interest on an instrument.  Financial strength and
solvency of an issuer are the primary factors influencing credit risk.  In
addition, lack of or inadequacy of collateral or credit enhancements for a fixed
income security may affect its credit risk.  Credit risk of a security may
change over its life and securities which are rated by rating agencies are often
reviewed and may be subject to downgrade.

"Interest rate risk" refers to the risks associated with market changes in
interest rates.  Interest rate changes may affect the value of a fixed income
security directly (especially in the case of

                                       22
<PAGE>
 
fixed rate securities) and directly (especially in the case of adjustable rate
securities). In general, rises in interest rates will negatively impact the
price of fixed rate securities and falling interest rates will have a positive
effect on price. The degree to which a security's price will change as a result
of changes in interest rates is measured by its "duration." For example, the
price of a bond with a 5 year duration would be expected under normal market
conditions to decrease 5% for every 1% increase in interest rates. Generally,
securities with longer maturities have a greater duration and thus are subject
to greater price volatility from changes in interest rates. Adjustable rate
instruments also react to interest rate changes in a similar manner although
generally to a lesser degree (depending, however, on the characteristics of the
re-set terms, including the index chosen, frequency of reset and reset caps or
floors, among other things).

Foreign Securities

The Equity Funds, Emerging Markets Income and Core Fixed Income are each
permitted to invest in securities issued by foreign governments or companies and
Convertible Securities and High Yield Bond may invest in securities issued by
foreign companies.  Investment in foreign securities involves special risks in
addition to the usual risks inherent in domestic investments.  These include:
political or economic instability; the unpredictability of international trade
patterns; the possibility of foreign governmental actions such as expropriation,
nationalization or confiscatory taxation; the imposition or modification of
foreign currency or foreign investment controls; the imposition of withholding
taxes on dividends, interest and gains; price volatility; and fluctuations in
currency exchange rates.  As compared to United States companies, foreign
issuers generally disclose less financial and other information publicly and are
subject to less stringent and less uniform accounting, auditing and financial
reporting standards.  Foreign countries typically impose less thorough
regulations on brokers, dealers, stock exchanges, insiders and listed companies
than does the United States, and foreign securities markets may be less liquid
and more volatile than domestic markets.  Investment in foreign securities
involves higher costs than investment in U.S. securities, including higher
transaction and custody costs as well as the imposition of additional taxes by
foreign governments.  In addition, security trading practices abroad may offer
less protection to investors such as the Funds.  Settlement of transactions in
some foreign markets may be delayed or may be less frequent than in the U.S.,
which could affect the liquidity of each Fund's portfolio.  Also, it may be more
difficult to obtain and enforce legal judgments against foreign corporate
issuers than against domestic issuers and it may be impossible to obtain and
enforce judgments against foreign governmental issues.

Foreign Currency Risks

Because foreign securities generally are denominated and pay dividends or
interest in foreign currencies, and some of the Funds hold various foreign
currencies from time to time, the value of the net assets of those Funds as
measured in United States dollars will be affected favorably or unfavorably by
changes in exchange rates.  Generally, currency exchange transactions will be
conducted on a spot (i.e., cash) basis at the spot rate prevailing in the
currency exchange market.  The cost of currency exchange transactions will
generally be the difference between the bid and offer spot rate of the currency
being purchased or sold.  In order to protect against uncertainty in the level
of future foreign currency exchange rates, the Equity Funds, Emerging Markets
Income

                                       23
<PAGE>
 
and Core Fixed Income are authorized to enter into certain foreign currency
future and forward contracts. However, it is not obligated to do so and,
depending on the availability and cost of these devices, the Fund may be unable
to use them to protect against currency risk. While foreign currency future and
forward contracts may be available, the cost of these instruments may be
prohibitively expensive so that the Fund may not to be able to effectively use
them

With respect to Emerging Markets Equities, Emerging Markets Income, Core Fixed
Income and Latin America Equities, the forward currency market for the purchase
or sale of U.S. dollars in most Latin American countries, including Mexico, is
not highly developed, and in certain Latin American countries, there may be no
such market.  If a devaluation of a Latin American currency is generally
anticipated, the Fund may not be able to contract to sell the currency at an
exchange rate more advantageous than that which would prevail after the
anticipated amount of devaluation, particularly as regards forward contracts for
local Latin American currencies in view of the relatively small, inactive or
even non-existent market for these contracts.  In the event the Funds hold
securities denominated in a currency that suffers a devaluation, the Funds' net
asset values will suffer corresponding reductions.  In this regard, in December
1994, the Mexican government determined to allow the Mexican peso to trade
freely against the U.S. dollar rather than within a controlled band, which
action resulted in a significant devaluation of the Mexican peso against the
dollar.  Further, in July 1997, the Thai and Philippine governments allowed the
baht and peso, respectively, to trade freely against the U.S. dollar resulting
in a sharp devaluation of both currencies, and in 1998 Russia did the same,
causing a sharp devaluation of the ruble.

Risks Associated With Emerging Market Countries

Investors should recognize that investing in securities of emerging market
countries through investment in the Asia Pacific Equities, Emerging Markets
Equities, Emerging Markets Income, International Equities, Latin America
Equities Funds and European Equities involves certain risks, and considerations,
including those set forth below, which are not typically associated with
investing in the United States or other developed countries.

Political and economic structures in many emerging markets countries may be
undergoing significant evolution and rapid development, and such countries may
lack the social, political and economic stability characteristics of more
developed countries.  Some of these countries may have in the past failed to
recognize private property rights and have at times nationalized or expropriated
the assets of private companies.

The securities markets of emerging market countries are substantially smaller,
less developed, less liquid and more volatile than the major securities markets
in the United States and other developed nations.  The limited size of many
emerging securities markets and limited trading volume in issuers compared to
volume of trading in U.S. securities or securities of issuers in other developed
countries could cause prices to be erratic for reasons apart from factors that
affect the quality of the securities.  For example, limited market size may
cause prices to be unduly influenced by traders who control large positions.
Adverse publicity and investors' perceptions, whether or not based on
fundamental analysis, may decrease the value and liquidity of portfolio
securities, especially in these markets.

                                       24
<PAGE>
 
In addition, emerging market countries' exchanges' and broker-dealers are
generally subject to less government and exchange regulation than their
counterparts in developed countries.  Brokerage commissions, dealer concessions,
custodial expenses and other transaction costs may be higher in emerging markets
than in developed countries.  As a result, Funds investing in emerging market
countries have operating expenses that are expected to be higher than other
funds investing in more established market regions.

Many of the emerging market countries may be subject to greater degree of
economic, political and social instability than is the case in the United
States, Canada, Australia, New Zealand, Japan and Western European and certain
Asian countries.  Such instability may result from, among other things, (i)
popular unrest associated with demands for improved political, economic and
social conditions, and (ii) internal insurgencies.  Such social, political and
economic instability could disrupt the financial markets in which the Asia
Pacific Equities, Emerging Markets Equities, Emerging Markets Income,
International Equities and Latin America Equities Funds invest and adversely
affect the value of a Fund's assets.

In certain emerging market countries governments participate to a significant
degree, through ownership or regulation, in their respective economies.  Action
by these governments could have a significant adverse effect on market prices of
securities and payment of dividends.  In addition, most emerging market
countries have experienced substantial, and in some periods extremely high,
rates of inflation.  Inflation and rapid fluctuation in inflation rates have had
and may continue to have very negative effects on the economies and securities
markets of certain emerging market countries.

Many of the currencies of emerging market countries have experienced
devaluations relative to the U.S. dollar, and major devaluations have
historically occurred in certain countries.  Any devaluations in the currencies
in which portfolio securities are denominated will have a detrimental impact on
Funds investing in emerging market countries.  Many emerging market countries
are experiencing currency exchange problems.  Countries have and may in the
future impose foreign currency controls and repatriation control.

Futures

There are certain risks inherent in the use of futures contracts and options on
futures contracts.  Successful use of futures contracts by a Fund is subject to
the ability of the Adviser to correctly predict movements in the direction of
interest rates or changes in market conditions.  In addition, there can be no
assurance that there will be a correlation between price movements in the
underlying securities, currencies or index and the price movements in the
securities which are the subject of hedge.  Positions in futures contracts and
options on futures contracts may be closed out only on the exchange or board of
trade on which they were entered into, and there can be no assurance that an
active market will exist for a particular contract or option at any particular
time.  If a Fund has hedged against the possibility of an increase in interest
rates or a decrease in the value of portfolio securities and interest rates fall
or the value of portfolio securities increase instead, a Fund will lose part or
all of the benefit of the increased value of securities that it has hedged
because it will have offsetting losses in its futures positions.  In addition,
in such

                                       25
<PAGE>
 
situations, if a Fund has insufficient cash, it may have to sell securities to
meet daily variation margin requirements at a time when it is disadvantageous to
do so. These sales of securities may, but will not necessarily, be at increased
prices that reflect the decline in interest rates. While utilization of futures
contracts and options on futures contracts may be advantageous to a Fund, if the
Fund is not successful in employing such instruments in managing its
investments, the Fund's performance will be worse than if the Fund not make such
investment in futures contracts and options on futures contracts.

Options

The successful use of options depends on the ability of the Adviser to forecast
interest rate and market movements correctly.  For example, if a Fund were to
write a call option based on the Adviser's expectation that the price of the
underlying security would fall, but the price were to rise instead, the Fund
could be required to sell the security upon exercise at a price below the
current market price.  Similarly, if a Fund were to write a put option based on
the Adviser's expectation that the price of the underlying security would rise,
but the price were to fall instead, the Fund could be required to purchase the
security upon exercise at a price higher than the current market price.

When it purchases an option, a Fund runs the risk that it will lose its entire
investment in the option in a relatively short period of time, unless the Fund
exercises the option or enters into a closing transaction with respect to the
option during the life of the option.  If the price of the underlying security
does not rise (in the case of a call) or fall (in the case of a put) to an
extent sufficient to cover the option premium and transaction costs, the Fund
will lose part or all of its investment in the option.  This contrasts with an
investment by the Fund in the underlying security, since the Fund will not lose
any of its investment in such security if the price does not change.

The effective use of options also depends on a Fund's ability to terminate
option positions at times when the Adviser deems it desirable to do so.
Although the Fund will take an option position only if the Adviser believes
there is a liquid secondary market for the option, there is no assurance that
the Fund will be able to effect closing transactions at any particular time or
at an acceptable price.

If a secondary trading market in options were to become unavailable, a Fund
could no longer engage in closing transactions.  Lack of investor interest might
adversely affect the liquidity of the market for particular options or series of
options.  A market may discontinue trading of a particular option or options
generally.  In addition, a market could become temporarily unavailable if
unusual events - such as volume in excess of trading or clearing capability -
were to interrupt its normal operations.

A market may at times find it necessary to impose restrictions on particular
types of options transactions, such as opening transactions.  For example, if an
underlying security ceases to meet qualifications imposed by the market or the
Options Clearing Corporation, new series of options on that security will no
longer be opened to replace expiring series, and opening transactions in
existing series may be prohibited.  If an options market were to become
unavailable, a Fund

                                       26
<PAGE>
 
which holds an option would be able to realize profits or limit losses only by
exercising the option, and a Fund which acted as option writer would remain
obligated under the option until expiration or exercise.

Special risks are presented by internationally-traded options of the type
certain of the Equity Funds, Emerging Markets Income and Core Fixed Income may
acquire.  Because of time differences between the United States and the various
foreign countries, and because different holidays are observed in different
countries, foreign options markets may be open for trading during hours or on
days when U.S. markets are closed.  As a result, option premiums may not reflect
the current prices of the underlying interest in the United States.

Risks Associated With Lower Rated Securities

The Convertible Securities and High Yield Bond portfolios consist primarily of
below investment grade corporate securities that are commonly known as junk
bonds.  In addition, the Equity Funds may invest in convertible securities and
Asia Pacific Equities, Core Fixed Income, Earnings Momentum, Aggressive Growth
Equities, Emerging Markets Equities, Emerging Markets Income,  European Equities
and Latin America Equities may invest in debt instruments rated below investment
grade.  Lower rated securities are traded in markets that may be relatively less
liquid and subject to greater changes in liquidity than the markets for higher
rated securities.

High yield/high risk securities can be classified into two categories:  (a)
securities issued without an investment grade rating and (b) securities whose
credit ratings have been downgraded below investment grade because of declining
investment fundamentals.  The first category includes securities issued by
"emerging credit" companies and companies which have experienced a leveraged
buyout or recapitalization.  Although the small and medium size companies that
constitute emerging credit issuers typically have significant operating
histories, these companies generally do not have strong enough operating results
to secure investment grade ratings from the rating agencies.  In addition, in
recent years there has been a substantial volume of high yield/high risk
securities issued by companies that have converted from public to private
ownership through leveraged buyout transactions and by companies that have
restructured their balance sheets through leveraged recapitalizations.  High
yield/high risk securities issued in these situations are used primarily to pay
existing stockholders for their shares or to finance special dividend
distributions to shareholders.  The indebtedness incurred in connection with
these transactions is often substantial and, as a result, often produces highly
leveraged capital structures which present special risks for the holders of such
securities.  Also, the market price of such securities may be more volatile to
the extent that expected benefits from the restructuring do not materialize.
The second category of high yield/high risk securities consists of securities of
former investment grade companies that have experienced poor operating
performance due to such factors as cyclical downtrends in their industry, poor
management or increased foreign competition.

Generally, lower-rated debt securities provide a higher yield than higher rated
debt securities of similar maturity but are subject to greater risk of loss of
principal and interest ("credit risk") than higher rated securities of similar
maturity.  They are generally considered to be subject to greater

                                       27
<PAGE>
 
risk than securities with higher ratings particularly in the event of a
deterioration of general economic conditions. The lower ratings of the high
yield/high risk securities which the Fund will purchase reflect a greater
possibility that the financial condition of the issuers, or adverse changes in
general economic conditions, or both, may impair the ability of the issuers to
make payments of principal and interest. The market value of a single lower-
rated fixed income security may fluctuate more than the market value of higher
rated securities, since changes in the creditworthiness of lower rated issuers
and in market perceptions of the issuers' creditworthiness tend to occur more
frequently and in a more pronounced manner than in the case of higher rated
issuers. High yield/high risk fixed income securities also tend to reflect
individual corporate developments to a greater extent than higher rated
securities. The securities in which the Fund invests are frequently subordinated
to senior indebtedness.

Since the high yield bond market is relatively new, its growth has paralleled a
long economic expansion, and it has not weathered a recession in its present
size and form.  An economic downturn or increase in interest rates may result in
a higher incidence of high yield bond defaults and is likely to have a negative
effect on the high yield bond market and on the value of the high yield/high
risk bonds in the Fund's portfolio, as well as on the ability of the bonds'
issuers to repay principal and interest.

The economy and interest rates affect high yield/high risk securities
differently from other securities.  The prices of high yield bonds have been
found to be less sensitive to interest rate changes than higher-rated
investments, but more sensitive to adverse economic changes or individual
corporate developments.  During an economic downturn or substantial period of
rising interest rates, highly leveraged issuers may experience financial stress
which would adversely affect their ability to service their principal and
interest payment obligations, to meet projected business goals, and to obtain
additional financing.  If the issuer of a bond owned by the Fund defaults, the
Fund may incur additional expenses to seek recovery.  In addition, periods of
economic uncertainty and changes can be expected to result in increased
volatility of market prices of high yield bonds and the Fund's asset value.
Furthermore, the market prices of high yield/high risk bonds structured as zero
coupon or pay-in-kind securities are affected to a greater extent by interest
rate changes and thereby tend to be more volatile than securities which pay
interest periodically and in cash.

To the extent there is a limited retail secondary market for particular high
yield bonds, these bonds may be thinly-traded and the Adviser's ability to
accurately value high yield bonds and the Fund's assets may be more difficult
because there is less reliable, objective data available.  In addition, the
Fund's ability to acquire or dispose of the bonds may be negatively-impacted.
Adverse publicity and investor perceptions, whether or not based on fundamental
analysis, may decrease the values and liquidity of high yield bonds, especially
in a thinly-traded market.  To the extent the Fund owns or may acquire illiquid
or restricted high yield bonds, these securities may involve special
registration responsibilities, liabilities and costs, and liquidity and
valuation difficulties.

Special tax considerations are associated with investing in lower rated debt
securities structured as zero coupon or pay-in-kind securities.  The Fund
accrues income on these securities prior to

                                       28
<PAGE>
 
the receipt of cash payments. The Fund must distribute substantially all of its
income to its shareholders to qualify for pass-through treatment under the tax
laws and may, therefore, have to dispose of its portfolio securities to satisfy
distribution requirements.

Underwriting and dealer spreads associated with the purchase of lower rated
bonds are typically higher than those associated with the purchase of high grade
bonds.

Risks Associated With Mortgage-Backed Securities

Credit and Market Risks of Mortgage-Backed Securities.  The investments by Core
Fixed Income, Total Return Mortgage-Backed Securities and Mortgage-Backed
Securities in fixed rate and floating rate mortgage-backed securities will
entail normal credit risks (i.e., the risk of non-payment of interest and
principal) and market risks (i.e., the risk that interest rates and other
factors will cause the value of the instrument to decline).  Many issuers or
servicers of mortgage-backed securities guarantee timely payment of interest and
principal on the securities, whether or not payments are made when due on the
underlying mortgages.  This kind of guarantee generally increases the quality of
a security, but does not mean that the security's market value and yield will
not change.  Like bond investments, the value of fixed rate mortgage-backed
securities will tend to rise when interest rates fall, and fall when rates rise.
Floating rate mortgage-backed securities will generally tend to have minimal
changes in price when interest rates rise or fall.  The value of all mortgage-
backed securities may also change because of changes in the market's perception
of the creditworthiness of the organization that issued or guarantees them.  In
addition, the mortgage-backed securities market in general may be adversely
affected by changes in governmental legislation or regulation.  Fluctuations in
the market value of mortgage-backed securities after their acquisition usually
do not affect cash income from such securities but are reflected in each Fund's
net asset value.  The liquidity of mortgage-backed securities varies by type of
security; at certain times a Fund may encounter difficulty in disposing of
investments.  Other factors that could affect the value of a mortgage-backed
security include, among other things, the types and amounts of insurance which a
mortgagor carries, the amount of time the mortgage loan has been outstanding,
the loan-to-value ratio of each mortgage and the amount of overcollateralization
of a mortgage pool.

Prepayment and Redemption Risk of Mortgage-Backed Securities.  Mortgage-backed
securities reflect an interest in monthly payments made by the borrowers who
receive the underlying mortgage loans.  Although the underlying mortgage loans
are for specified periods of time, such as 20 or 30 years, the borrowers can,
and typically do, pay them off sooner.  In such an event, the mortgage-backed
security which represents an interest in such underlying mortgage loan will be
prepaid.  A borrower is more likely to prepay a mortgage which bears a
relatively high rate of interest.  This means that in times of declining
interest rates, a portion of the Fund's higher yielding securities are likely to
be redeemed and the Fund will probably be unable to replace them with securities
having as great a yield.  Prepayments can result in lower yields to
shareholders.  The increased likelihood of prepayment when interest rates
decline also limits market price appreciation of mortgage-backed securities.  In
addition, a mortgage-backed security may be subject to redemption at the option
of the issuer.  If a mortgage-backed security held by a Fund is called for
redemption, the Fund will be required to permit the issuer to redeem

                                       29
<PAGE>
 
the security, which could have an adverse effect on the Fund's ability to
achieve its investment objective.

Collateralized Mortgage Obligations.  There are certain risks associated
specifically with CMOs.  CMOs issued by private entities are not obligations
issued or guaranteed by the United States Government, its agencies or
instrumentalities and are not guaranteed by any government agency, although the
securities underlying a CMO may be subject to a guarantee.  Therefore, if the
collateral securing the CMO, as well as any third party credit support or
guarantees, is insufficient to make payment, the holder could sustain a loss.
In addition, the average life of CMOs is determined using mathematical models
that incorporate prepayment assumptions and other factors that involve estimates
of future economic and market conditions.  These estimates may vary from actual
future results, particularly during periods of extreme market volatility.
Further, under certain market conditions, such as those that occurred in 1994,
the average weighted life of certain CMOs may not accurately reflect the price
volatility of such securities.  For example, in periods of supply and demand
imbalances in the market for such securities and/or in periods of sharp interest
rate movements, the prices of CMOs may fluctuate to a greater extent than would
be expected from interest rate movements alone.

Stripped Mortgage Securities.  Part of the investment strategy of Core Fixed
Income, Total Return Mortgage-Backed Securities and Mortgage-Backed Securities
involves interest-only Stripped Mortgage Securities.  These investments are
highly sensitive to changes in interest and prepayment rates and tend to be less
liquid than other CMOs.

Inverse Floaters. Total Return Mortgage-Backed and Mortgage-Backed Securities
invest in inverse floaters, a class of CMOs with a coupon rate that resets in
the opposite direction from the market rate of interest to which it is indexed
such as LIBOR or COFI.  Any rise in the index rate (as a consequence of an
increase in interest rates) causes a drop in the coupon rate of an inverse
floater while any drop in the index rate causes an increase in the coupon of an
inverse floater.  An inverse floater may be considered to be leveraged to the
extent that its interest rate varies by a magnitude that exceeds the magnitude
of the change in the index rate of interest.  The higher degree of leverage
inherent in inverse floaters is associated with greater volatility in their
market prices.

Adjustable Rate Mortgages.  ARMs contain maximum and minimum rates beyond which
the mortgage interest rate may not vary over the lifetime of the security.  In
addition, certain ARMs provide for additional limitations on the maximum amount
by which the mortgage interest rate may adjust for any single adjustment period.
Alternatively, certain ARMs contain limitations on changes in the required
monthly payment.  In the event that a monthly payment is not sufficient to pay
the interest accruing on an ARM, any such excess interest is added to the
principal balance of the mortgage loan, which is repaid through future monthly
payments.  If the monthly payment for such an instrument exceeds the sum of the
interest accrued at the applicable mortgage interest rate and the principal
payment required at such point to amortize the outstanding principal balance
over the remaining term of the loan, the excess is utilized to reduce the then
outstanding principal balance of the ARM.

                                       30
<PAGE>
 
Asset-Backed Securities.  Certain asset-backed securities do not have the
benefit of the same security interest in the related collateral as do mortgage-
backed securities.  Credit card receivables are generally unsecured, and the
debtors are entitled to the protection of a number of state and federal consumer
credit laws, many of which give such debtors the right to set off certain
amounts owed on the credit cards, thereby reducing the balance due.  In
addition, some issuers of automobile receivables permit the servicers to retain
possession of the underlying obligations.  If the servicer were to sell these
obligations to another party, there is a risk that the purchaser would acquire
an interest superior to that of the holders of the related automobile
receivables.

Rating Categories

A description of the rating categories as published by Moody's and S&P is set
forth in the Appendix to this Statement of Additional Information.  Ratings
assigned by Moody's and/or S&P to securities acquired by a Fund reflect only the
views of those agencies as to the quality of the securities they have undertaken
to rate.  It should be emphasized, however, that ratings are relative and
subjective and are not absolute standards of quality.  There is no assurance
that a rating assigned initially will not change.  A Fund may retain a security
whose rating has changed or has become unrated.

Restricted Securities

Each Fund may invest in securities which are subject to restrictions on resale
because they have not been registered under the Securities Act of 1933, as
amended (the "Securities Act"), or which are otherwise not readily marketable.
These securities are generally referred to as private placements or restricted
securities.  The Adviser, pursuant to procedures adopted by the Board of
Directors of the Company, will make a determination as to the liquidity of each
restricted security purchased by a Fund.  If a restricted security is determined
to be "liquid," it will not be included within the category "illiquid
securities," which under each Bond Fund's and Equity Fund's current policies may
not exceed 15% of the Fund's net assets and which under Money Market's current
policies may not exceed 10% of the Fund's net assets.

Limitations on the resale of restricted securities may have an adverse effect on
their marketability, and may prevent a Fund from disposing of them promptly at
reasonable prices.  A Fund may have to bear the expense of registering such
securities for resale and the risk of substantial delays in effecting such
registration.  The Securities and Exchange Commission has recently adopted Rule
144A under the Securities Act, which permits each Fund to sell restricted
securities to qualified institutional buyers without limitation.  The Rule 144A
marketplace of sellers and qualified institutional buyers is new and still
developing and may take a period of time to develop into a mature liquid market.
As such, the market for certain private placements purchased pursuant to Rule
144A may be initially small or may, subsequent to purchase, become illiquid.
Furthermore, the Adviser may not possess all the information concerning an issue
of securities that it wishes to purchase in a private placement to which it
would normally have had access, had the registration statement necessitated by a
public offering been filed with the Securities and Exchange Commission.

                                       31
<PAGE>
 
Options Transactions

The effective use of options also depends on a Fund's ability to terminate
option positions at times when the Adviser deems it desirable to do so.  Prior
to exercise or expiration, an option position can only be terminated by entering
into a closing purchase or sale transaction.  If a covered call option writer is
unable to effect a closing purchase transaction or to purchase an offsetting OTC
Option, it cannot sell the underlying security until the option expires or the
option is exercised.  Accordingly, a covered call option writer may not be able
to sell an underlying security at a time when it might otherwise be advantageous
to do so.  A secured put option writer who is unable to effect a closing
purchase transaction or to purchase an offsetting OTC Option would continue to
bear the risk of decline in the market price of the underlying security until
the option expires or is exercised.  In addition, a secured put writer would be
unable to utilize the amount held in cash or U.S. Government Securities or other
high grade short-term obligations as security for the put option for other
investment purposes until the exercise or expiration of the option.

A Fund's ability to close out its position as a writer of an option is dependent
upon the existence of a liquid secondary market.  There is no assurance that
such a market will exist, particularly in the case of OTC Options, as such
options will generally only be closed out by entering into a closing purchase
transaction with the purchasing dealer.  However, the Fund may be able to
purchase an offsetting option which does not close out its position as a writer
but constitutes an asset of equal value to the obligation under the option
written.  If the Fund is not able to either enter into a closing purchase
transaction or purchase an offsetting position, it will be required to maintain
the securities subject to the call, or the collateral underlying the put, even
though it might not be advantageous to do so, until a closing transaction can be
entered into (or the option is exercised or expires).

Among the possible reasons for the absence of a liquid secondary market on an
exchange are:  (a) insufficient trading interest in certain options; (b)
restrictions on transactions imposed by an exchange; (c) trading halts,
suspensions or other restrictions imposed with respect to particular classes or
series of options or underlying securities; (d) interruption of the normal
operations on an exchange; (e) inadequacy of the facilities of an exchange or
the OCC or other relevant clearing corporation to handle current trading volume;
or (f) a decision by one or more exchanges to discontinue the trading of options
(or a particular class or series of options), in which event the secondary
market on that exchange (or in that class or series of options) would cease to
exist, although outstanding options on that exchange that had been issued by the
relevant clearing corporation as a result of trades on that exchange would
generally continue to be exercisable in accordance with their terms.

In the event of the bankruptcy of a broker through which a Fund engages in
transactions in options, the Fund could experience delays and/or losses in
liquidating open positions purchased or sold through the broker and/or incur a
loss of all or part of its margin deposits with the broker.  Similarly, in the
event of the bankruptcy of the writer of an OTC Option purchased by a Fund, the
Fund could experience a loss of all or part of the value of the option.
Transactions are entered into by a Fund only with brokers or financial
institutions deemed creditworthy by the Fund's management.

                                       32
<PAGE>
 
Each of the exchanges has established limitations governing the maximum number
of options on the same underlying security or futures contract (whether or not
covered) which may be written by a single investor, whether acting alone or in
concert with others (regardless of whether such options are written on the same
or different exchanges or are held or written on one or more accounts or through
one or more brokers).  An exchange may order the liquidation of positions found
to be in violation of these limits and it may impose other sanctions or
restrictions.  These position limits may restrict the number of listed options
which a Fund may write.

The hours of trading for options may not conform to the hours during which the
underlying securities are traded.  To the extent that the option markets close
before the markets for the underlying securities, significant price and rate
movements can take place in the underlying markets that cannot be reflected in
the option markets.

Futures Contracts and Options on Futures
    
There are certain risks inherent in the use of futures contracts and options on
futures contracts.  Successful use of futures contracts by a Fund is subject to
the ability of the Adviser to correctly predict movements in the direction of
interest rates or changes in market conditions.  In addition, there can be no
assurance that there will be a correlation between price movements in the
underlying securities, currencies or index and the price movements in the
securities which are the subject of the hedge.     

Positions in futures contracts and options on futures contracts may be closed
out only on the exchange or board of trade on which they were entered into, and
there can be no assurance that an active market will exist for a particular
contract or option at any particular time.  If a Fund has hedged against the
possibility of an increase in interest rates or a decrease in the value of
portfolio securities and interest rates fall or the value of portfolio
securities increase instead, a Fund will lose part or all of the benefit of the
increased value of securities that it has hedged because it will have offsetting
losses in its futures positions.  In addition, in such situations, if a Fund has
insufficient cash, it may have to sell securities to meet daily variation margin
requirements at a time when it may be disadvantageous to do so.  These sales of
securities may, but will not necessarily be at increased prices that reflect the
decline in interest rates.  While utilization of futures contracts and options
on futures contracts may be advantageous to the Fund, if the Fund is not
successful in employing such instruments in managing the Fund's investments, the
Fund's performance will be worse than if the Fund did not make such investments.

Each Fund will enter into transactions in futures contracts for hedging purposes
only, including without limitation, futures contracts that are "bona fide
hedges" as defined by the CFTC.  In connection with the purchase of sale of
futures contracts, a Fund will be required to either (i) segregate sufficient
cash or other liquid assets to cover the outstanding position or (ii) cover the
futures contract by either owning the instruments underlying the futures
contracts or by holding a portfolio of securities with characteristics
substantially similar to the underlying index or stock index comprising the
futures contracts or by holding a separate offsetting option permitting it to
purchase or sell the same futures contract.  A call option is "covered" if
written against securities owned by the Fund writing the option or if written
against related securities the Fund holds.  A put

                                       33
<PAGE>
 
option is "covered" if the Fund writing the option maintains at all time cash,
short-term Treasury obligations or other liquid assets with a value equal to the
option exercise price in a segregated account with the Fund's custodian, or if
it has bought and holds a put on the same security (and on the same amount of
securities) where the exercise price of the put held by the Fund is equal to or
greater than the exercise price of the put written by the Fund.

Exchanges limit the amount by which the price of a futures contract may move on
any day.  If the price moves equal the daily limit on successive days, then it
may prove impossible to liquidate a futures position until the daily limit moves
have ceased.  In the event of adverse price movements, a Fund would continue to
be required to make daily cash payments of variation margin on open futures
positions.  In such situations, if a Fund has insufficient cash, it may have to
sell portfolio securities to meet daily variation margin requirements at a time
when it may be disadvantageous to do so.  In addition, a Fund may be required to
take or make delivery of the instruments underlying interest rate futures
contracts it holds at a time when it is disadvantageous to do so.  The inability
to close out options and futures positions could also have an adverse impact on
a Fund's ability to effectively hedge its portfolio.

Futures contracts and options thereon which are purchased or sold on foreign
commodities exchanges may have greater price volatility than their U.S.
counterparts.  Furthermore, foreign commodities exchanges may be less regulated
and under less governmental scrutiny than U.S. exchanges.  Brokerage
commissions, clearing costs and other transaction costs may be higher on foreign
exchanges.  Greater margin requirements may limit a Fund's ability to enter into
certain commodity transactions on foreign exchanges.  Moreover, differences in
clearance and delivery requirements on foreign exchanges may occasion delays in
the settlement of a Fund's transactions effected on foreign exchanges.

In the event of the bankruptcy of a broker through which a Fund engages in
transactions in futures or options thereon, the Fund could experience delays
and/or losses in liquidating open positions purchased or sold through the broker
and/or incur a loss of all or part of its margin deposits with the broker.
Similarly, in the event of the bankruptcy, of the writer of an OTC option
purchased by a Fund, the Fund could experience a loss of all or part of the
value of the option.  Transactions are entered into by a Fund only with brokers
or financial institutions deemed creditworthy by the Adviser.

There is no assurance that a liquid secondary market will exist for futures
contracts and related options in which a Fund may invest.  In the event a liquid
market does not exist, it may not be possible to close out a futures position,
and in the event of adverse price movements, a Fund would continue to be
required to make daily cash payments of variation margin.  In addition,
limitations imposed by an exchange or board of trade on which futures contracts
are traded may compel or prevent a Fund from closing out a contract which may
result in reduced gain or increased loss to the Fund.  The absence of a liquid
market in futures contracts might cause a Fund to make or take delivery of the
underlying securities (currencies) at a time when it may be disadvantageous to
do so.

Compared to the purchase or sale of futures contracts, the purchase of call or
put options on futures contracts involves less potential risk to a Fund because
the maximum amount at risk is the premium

                                       34
<PAGE>
 
paid for the options (plus transaction costs). However, there may be
circumstances when the purchase of a call or put option on a futures contract
would result in a loss to a Fund notwithstanding that the purchase or sale of a
futures contract would not result in a loss, as in the instance where there is
no movement in the prices of the futures contract or underlying securities
(currencies).

Options on foreign currency futures contracts may involve certain additional
risks.  Trading options on foreign currency futures contracts is relatively new.
The ability to establish and close out positions on such options is subject to
the maintenance of a liquid secondary market.  To reduce this risk, a Fund will
not purchase or write options on foreign currency futures contracts unless and
until, in the Adviser's opinion, the market for such options has developed
sufficiently that the risks in connection with such options are not greater than
the risks in connection with transactions in the underlying foreign currency
futures contracts.

Portfolio Turnover

The portfolio turnover rate is calculated by dividing the lesser of the value of
purchases or sales of portfolio securities for the year by the monthly average
value of portfolio securities.  For example, a portfolio turnover rate of 100%
would occur if all of a Fund's securities that are included in the computation
of turnover were replaced once during a period of one year.  Securities with
remaining maturities of one year or less at the date of acquisition are excluded
from the calculation.
    
Certain practices that may be employed by the Funds could result in high
portfolio turnover.  For example, portfolio securities may be sold in
anticipation of a rise in interest rates (market decline) or purchased in
anticipation of a decline in interest rates (market rise) and later sold.  In
addition, a security may be sold and another of comparable quality purchased at
approximately the same time to take advantage of what the Adviser believes to be
a temporary disparity in the normal yield relationship between the two
securities.  These yield disparities may occur for reasons not directly related
to the investment quality of particular issues or the general movement of
interest rates, such as changes in the overall demand for, or supply of, various
types of securities.  High portfolio turnover can result in increased
transaction costs for shareholders.  High turnover generally results from the 
adviser's effort to maximize return for a particular period.     

Brokerage Practices

The Adviser is responsible for the placement of the Funds' portfolio
transactions and the negotiation of prices and commissions, if any, with respect
to such transactions.  Fixed income and unlisted equity securities are generally
purchased from a primary market maker acting as principal on a net basis without
a stated commission but at prices generally reflecting a dealer spread.  Listed
equity securities are normally purchased through brokers in transactions
executed on securities exchanges involving negotiated commissions.  Both fixed
income and equity securities are also purchased in underwritten offerings at
fixed prices which include discounts to underwriters and/or concessions to
dealers.  In placing a portfolio transaction, the Adviser seeks to obtain the
best execution for the Fund, taking into account such factors as price
(including the applicable dealer spread or commission, if any), size of order,
difficulty of execution and operational facilities of the firm involved and the
firm's risk in positioning a block of securities.

                                       35
<PAGE>
 
Consistent with its policy of securing best execution, in selecting broker-
dealers and negotiating any commissions or prices involved in Fund transactions,
the Adviser considers the range and quality of the professional services
provided by such firms.  Brokerage services include the ability to most
effectively execute large orders without adversely impacting markets and
positioning securities in order to enable the Adviser to effect orderly
purchases or sales for a Fund.  Accordingly, transactions will not always be
executed at the lowest available commission.  Consistent with the Conduct Rules
of the National Association of Securities Dealers, Inc., and subject to seeking
the most favorable price and execution available  and other such polices as the
Board of Directors may determine, the Adviser may consider sales of shares of a
Fund as a factor in the selection of broker-dealers to execute the Fund's
portfolio transactions.  In addition, the Adviser may effect transactions which
cause a Fund to pay a commission or net price in excess of a commission or net
price which another broker-dealer would have charged if the Adviser first
determines that such commission or net price is reasonable in relation to the
value of the brokerage and research services provided by the broker-dealer to
the Fund.

Research services include such items as reports on industries and companies,
economic analyses and review of business conditions, portfolio strategy,
analytic computer software, account performance services, computer terminals and
various trading and/or quotation equipment.  They also include advice from
broker-dealers as to the value of securities and availability of securities,
buyers, and sellers.  In addition, they include recommendations as to purchase
and sale of individual securities and timing of transactions.

Fixed income securities are generally purchased from the issuer or a primary
market maker acting as principal on a net basis with no brokerage commission
paid by the client.  Such securities, as well as equity securities, may also be
purchased from underwriters at prices which include underwriting fees.

The Adviser maintains an internal allocation procedure to identify those broker-
dealers who have provided it with research services and endeavors to place
sufficient transactions with them to ensure the continued receipt of research
services the Adviser believes are useful.  When the Adviser receives products or
services that are used both for research and other purposes, it makes a good
faith allocation.  While the non-research portion will be paid in cash by the
Adviser, the portion attributable to research may be paid through brokerage
commissions.
    
Research services furnished by broker-dealers may be used in providing services
for any or all of the clients of the Adviser, as well as clients of affiliated
companies, and may be used in connection with accounts other than those which
pay commissions to the broker-dealers providing the research services.  During

INVESTMENT RESTRICTIONS

The investment restrictions numbered 1 through 8 below have been adopted by the
Company with respect to the Funds as fundamental policies (except as otherwise
provided in 1).  A fundamental policy affecting a particular Fund may not be
changed without the vote of a majority of the outstanding shares of the affected
Fund.  Investment restrictions 9 and 10 with respect to a Fund may be changed by
vote of a majority of the Company's Board of Directors at any time.

Investment policies adopted by the Company are:

1.   No Fund will borrow money, except that (a) a Fund may borrow from banks for
     temporary or emergency (not leveraging) purposes including the meeting of
     redemption requests that might otherwise require the untimely disposition
     of securities, (b) Core Fixed Income, Total Return Mortgage-Backed
     Securities, Mortgage-Backed Securities, Latin America Equities and Money
     Market may each enter into reverse repurchase agreements, (c) Core Fixed
     Income Total Return Mortgage-Backed Securities and Mortgage-Backed
     Securities may utilize mortgage dollar rolls, and (d) each Fund other than
     Money Market may enter into futures contracts for hedging purposes subject
     to the conditions set forth in paragraph 8 below.  The total amount
     borrowed by a Fund (including, for this purpose, reverse repurchase
     agreements and mortgage dollar rolls) at any time will not exceed 30% (or,
     in the case of Money Market, 10%) of the value of the Fund's total assets
     (including the amount borrowed) valued at market less liabilities (not
     including the amount borrowed) at the time the borrowing is made.  As an
     operating policy, whenever borrowings pursuant to (a) exceed 5% (or, in the
     case of Money Market, 10%) of the value of a Fund's total assets, the Fund
     will not purchase any securities.

2.  No Fund will issue senior securities as defined in the 1940 Act, provided
    that the Funds may (a) enter into repurchase agreements; (b) purchase
    securities on a when-issued or delayed delivery basis; (c) purchase or sell
    financial futures contracts or options thereon; and (d) borrow money in
    accordance with the restrictions described in paragraph 1 above.

3.  No Fund will underwrite securities of other companies, except insofar as the
    Fund might be deemed to be an underwriter for purposes of the Securities Act
    by virtue of disposing of portfolio securities.

4.  No Fund will purchase any securities that would cause 25% or more of the
    value of the Fund's total assets at the time of purchase to be invested in
    the securities of any one particular industry or group of industries,
    provided that this limitation shall not apply to any Fund's purchase of U.S.
    Government Securities, and, in the case of Money Market, to the purchase of
    obligations of domestic branches of United States banks.  The European
    Equities Fund may invest more than 25% of the value of its total assets in a
    single European country, the International Equities Fund may invest more
    than 25% of the value of its total assets in shares of registered investment
    companies, the Japanese Equities Fund may invest more than 25% of the value
    of its total assets in debt securities issued or guaranteed by the Japanese
    government and the Emerging Markets Income Fund may invest more than 25% of
    the value of its total assets in debt securities issued or guaranteed by the
    governments of Emerging Markets Countries.  In determining industry
    classifications for foreign issuers, each Fund will use reasonable
    classifications that are not so broad that the primary economic
    characteristic of the companies in a single class are materially different.
    Each Fund will determine such classifications of foreign issuers based on
    the issuer's principal or major business activities.

5.  No Fund will invest in real estate, real estate mortgage loans, residual
    interests in REMICs, oil, gas and other mineral leases (including other
    universal exploration or development programs), or real estate limited
    partnerships, except that a Fund may purchase securities backed by real
    estate or interests therein, or issued by companies, including real estate
    investment trusts, which invest in real estate or interests therein, and
    except that Core Fixed Income, Total Return Mortgage-Backed Securities and
    Mortgage-Backed Securities are not prohibited from investing in real estate
    mortgage loans.

6.  No Fund may make loans of cash except by purchasing qualified debt
    obligations or entering into repurchase agreements.

7.  Each Fund may effect short sales of securities or maintain a short position
    only if the Fund at the time of sale either owns or has the right to acquire
    at no additional cost securities equivalent in kind and amount to those
    sold.

8.  No Fund will invest in commodities or commodities contracts, except that
    each Bond Fund or Equity Fund may enter into futures contracts or purchase
    related options thereon if, immediately thereafter, the amount committed to
    margin plus the amount paid for premiums for unexpired options on futures
    contracts does not exceed 5% of the value of the Fund's total assets, after
    taking into account unrealized gains and unrealized losses on such contracts
    it has entered into, provided, however, that in the case of an option that
    is in-the-money (the exercise price of the call (put) option is less (more)
    than the market price of the underlying security) at the time of purchase,
    the in-the-money amount may be excluded in

                                       38
<PAGE>
 
    calculating the 5%. The entry into foreign currency forward contracts shall
    not be deemed to involve investing in commodities.

9.  No Fund will purchase securities on margin, except that a Fund may obtain
    any short-term credits necessary for clearance of purchases and sales of
    securities.  For purposes of this restriction, the deposit or payment of
    initial or variation margin in connection with futures contracts and related
    options will not be deemed to be a purchase of securities on margin.

10. No Fund will purchase the securities of an issuer for the purpose of
    acquiring control or management thereof except that Asia Pacific Equities,
    Emerging Markets Equities and Latin America Equities may acquire the
    securities of subsidiaries in order to facilitate investing in the
    securities of foreign issuers.

The percentage limitations contained in the restrictions listed above apply,
with the exception of (1), at the time of purchase or initial investment and any
subsequent change in any applicable percentage resulting from market
fluctuations or other changes in total or net assets does not require
elimination of any security from the Fund.

DIRECTORS AND OFFICERS OF THE COMPANY

A board of five directors is responsible for overseeing the Fund's affairs.  The
Fund has an executive committee, consisting of Marc I. Stern, Chairman, John C.
Argue and Thomas E. Larkin, which may act for the Board of Directors between

INVESTMENT ADVISORY AND SUB-ADVISORY AGREEMENTS

The Company and the Adviser are parties to an Investment Management and Advisory
Agreement ("Advisory Agreement").  The Adviser was organized in 1987 as a
wholly-owned subsidiary of The TCW Group, Inc. (formerly TCW Management
Company).  Robert A. Day may be deemed to be a control person of the Adviser by
the virtue of the aggregate ownership of Mr. Day and his family of more than 25%
of the outstanding voting stock of The TCW Group, Inc.  Under the Advisory
Agreement, the Company retains the Adviser to manage the investment of its
assets, to place orders for the purchase and sale of its portfolio securities,
to administer its day-to-day operations, and to be responsible for overall
management of the Company's business affairs subject to control by the Board of
Directors of the Company.  The Adviser is responsible for obtaining and
evaluating economic, statistical, and financial data and for formulating and
implementing investment programs in furtherance of the Company's investment
objectives.

The Adviser has retained, at its sole expense, two affiliated companies to act
as Sub-Adviser to certain of the Funds.  TCW Asia Limited acts as a Sub-Adviser
to the Asia Pacific Equities and Emerging Markets Equities Funds and TCW London
International, Limited (regulated by I.M.R.O.) is a Sub-Adviser to Emerging
Markets Equities, European Equities, Japanese Equities and International
Equities Funds.  TCW Asia and TCW London are wholly-owned subsidiaries of The
TCW Group, Inc. (collectively, TCW Asia Limited and TCW London International,
Ltd. are the "Sub-Advisers").  The Sub-Advisers provide their respective Funds
with investment advice and portfolio management subject to the overall
supervision of the Adviser.

The Adviser furnishes to the Company office space at such places as are agreed
upon from time to time and all office facilities, business equipment, supplies,
utilities and telephone service necessary for managing the affairs and
investments and arranges for officers or employees of the Adviser to serve,
without compensation from the Company, as officers, directors or employees of
the Company if desired and reasonably required by the Company.

The fee allocable to each Fund is calculated daily by applying the annual
management fee percent for the Fund to the Fund's net asset value.  The fee is
payable for each calendar month as soon as practicable after the end of that
month.  In addition, prior to fiscal year ended October 31, 1998, each Bond and
Equity Fund and Emerging Markets Income reimbursed the Adviser for the costs of
providing accounting services to the Fund, including maintaining the Fund's
financial books and records, calculating its daily net asset value, and
preparing its financial statements, in an amount not exceeding $35,000 for the
applicable fiscal year (subject to any expense limit described below).  Money
Market also reimburses the Adviser for the Fund's accounting services, but in an
amount not exceeding 0.10% of the Fund's average daily net assets.  The total
amounts paid, exclusive of any expense reimbursement by the Adviser and payment

Large Cap Value and Emerging Markets Income were:  0.91% (after expense
reimbursement), 0.55% (after expense reimbursement) and 1.53%, respectively.

The Advisory Agreement also provides that each Fund (except for Money Market)
will reimburse the Adviser for the Fund's organizational expenses.  Such
organizational expenses will be amortized by each Fund over five years.

The Advisory Agreement was approved by each Fund's initial shareholder and will
continue in effect as to each Fund initially for two years and thereafter from
year to year if such continuance is specifically approved at least annually by
(a) the Board of Directors of the Company or by the vote

                                       44
<PAGE>
 
of a majority of the outstanding voting securities of the Fund, and (b) vote of
a majority of the directors who are not "interested persons" of the Company or
the Adviser (the Independent Directors), cast in person at a meeting called for
the purpose of voting on such approval. The Advisory Agreement may be terminated
without penalty at any time on 60 days' written notice, by vote of a majority of
the Board of Directors of the Company or by vote of a majority of the
outstanding voting securities of the Fund. The Advisory Agreement terminates
automatically in the event of assignment.

The Company has acknowledged that the name "TCW" is owned by The TCW Group, Inc.
(formerly, TCW Management Company) ("TCW"), the parent of the Adviser.  The
Company has agreed to change its name and the name of the Funds at the request
of TCW if any advisory agreement into which TCW or any of its affiliates and the
Company may enter is terminated.

The Advisory Agreement and Sub-Advisory Agreements also provides that the
Adviser and Sub-Advisers shall not be liable to the Company for any actions or
omissions if it acted in good faith without gross negligence, willful
misfeasance, bad faith, or from reckless disregard of their duties.

DISTRIBUTION OF COMPANY SHARES

TCW Brokerage Services ("Distributor") serves as the nonexclusive distributor of
each class of the Company's shares pursuant to an Amended and Restated
Distribution Agreement ("Distribution Agreement") with the Company which is
subject to approval by the Board.  The Distribution Agreement is terminable
without penalty, on not less than 60 days' notice, by the Company's Board of
Directors, by vote of holders of a majority of the Company's shares, or by the
Distributor.

The Company offers two classes of shares:  Institutional Class shares and Class
N shares.  Shares of the Institutional Class are offered primarily for direct
investment by investors such as pension and profit sharing plans, employee
benefit trusts, endowment, foundations, corporations and high net individuals.
Class N shares are offered through firms which are members of the National
Association of Securities Dealers, Inc. ("NASD"), and which have dealer
agreements with the Distributor.

The Company has adopted a Plan Pursuant to Rule 18f-3 under the 1940 Act (" Rule
18f-3 Plan").  Under the Rule 18f-3 Plan, shares of each class of each Fund
represent an equal pro rata interest in such Fund and, generally, have identical
voting, dividend, liquidation, and other rights, preferences, powers,
restrictions, limitations, qualifications and terms and conditions, except that:
(a) each class has a different designation; (b) each class of shares bears any
class-specific expenses allocated to it; and (c) each class has exclusive voting
rights on any matter submitted to shareholders that relates solely to its
distribution or service arrangements, and each class has separate voting rights
on any matter submitted to shareholders in which the interests of one class
differ from the interests of any other class.  In addition, each class may have
a differing sales charge structure, and differing exchange and conversion
features.

The Company also has adopted a distribution plan pursuant to Rule 12b-1 under
the 1940 Act ("Distribution Plan") with respect to the Class N shares of each
Fund.  Under the terms of the

                                       45
<PAGE>
 
Distribution Plan, each Fund compensates the Distributor at a rate equal to
0.25% of the average daily net assets of the Fund attributable to its Class N
shares for distribution and related services. The Distributor may pay any or all
of the fee payable to it for distribution and related services to the firms that
are members of the NASD, subject to compliance by the firms with the terms of
the dealer agreement between the firm and the Distributor. Under the terms of
the Distribution Plan, services which a firm will provide under a dealer
agreement may include, but are not limited to, the following functions:
providing facilities to answer questions from prospective investors about a
Fund; receiving and answering correspondence, including requests for
prospectuses and statements of additional information; preparing, printing and
delivering prospectuses and shareholder reports to prospective shareholders;
complying with federal and state securities laws pertaining to the sale of Class
N shares; and assisting investors in completing application forms and selecting
dividend and other account options.

The Distribution Plan provides that it may not be amended to materially increase
the costs which Class N shareholders may bear under the Plan without the
approval of a majority of the outstanding voting securities of Class N, and by
vote of a majority of both (i) the Board of Directors of the Company, and (ii)
those Directors of the Company who are not "interested persons" of the Company
(as defined in the 1940 Act) and who have no direct or indirect financial
interest in the operation of the Plan or any agreements related to it cast in
person at a meeting called for the purpose of voting on the Plan and any related
amendments.

The Distribution Plan provides that it may not take effect until approved by a
vote of a majority of both (i) the Board of Directors of the Company, and (ii)
those Directors of the Company who are not "interested persons" of the Company
(as defined in the 1940 Act) and who have no direct or indirect financial
interest in the operation of the Plan or any agreements related to it cast in
person at a meeting called for the purpose of voting on the Plan and any related
amendments.  The Administrative Plans were approved by the Trustees, including
the disinterested Trustees, at a meeting held on December 17, 1998.

The Distribution Plan provides that it shall continue in effect so long as such
continuance is specifically approved at least annually by the by a vote of a
majority of both (i) the Board of Directors of the Company, and (ii) those
Directors of the Company who are not "interested persons" of the Company (as
defined in the 1940 Act) and who have no direct or indirect financial interest
in the operation of the Plan or any agreements related to it cast in person at a
meeting called for the purpose of voting on the Plan and any related amendments.

ADMINISTRATION AGREEMENT

Investors Bank & Trust Company ("Administrator") serves as the administrator of
the Company pursuant to an Administration Agreement.  Under the Administration
Agreement, the Administrator will provide certain administrative services to the
Company, including:  fund accounting; calculation of the daily net asset value
of each Fund; monitoring the Company's expense accruals; calculating monthly
total return and yield figures; prospectus and statement of additional
information compliance monitoring; preparing certain financial statements of the
Company; and preparing the Company's Form N-SAR.

DETERMINATION OF NET ASSET VALUE

As discussed in the Prospectus, the Company will not calculate the net asset
value of the Funds on certain holidays, weekends and when there is no activity
in a Fund's shares.  On those days, securities held by a Fund may nevertheless
be actively traded, and the value of the Fund's shares could be significantly
affected.

A Fund determines its net asset value per share by subtracting its liabilities
(including accrued expenses and dividends payable) from its total assets (the
market value of the securities the Fund holds plus cash and other assets,
including income accrued but not yet received) and dividing the result by the
total number of shares outstanding.

HOW TO BUY AND REDEEM SHARES

Shares in a Fund may be purchased and redeemed in the manner described in the
Prospectus and in this Statement of Additional Information.

Computation of Public Offering Prices

The Funds offer their shares to the public on a continuous basis.  The public
offering price per share of each Fund is equal to its net asset value per share
next computed after receipt of a purchase order.  See "Determination of Net
Asset Value", above.

Distributions in Kind

If the Board of Directors determines that it would be detrimental to the best
interests of the remaining shareholders of a Fund to make a redemption payment
wholly in cash, the Fund may pay, in accordance with SEC rules, any portion of a
redemption in excess of the lesser of $250,000 or 1% of the Fund's net assets by
distribution in kind of portfolio securities in lieu of cash.  Shareholders
receiving distributions in kind may incur brokerage commissions or other costs
when subsequently disposing of shares of those securities.

HOW TO EXCHANGE SHARES

A shareholder may exchange all or part of its shares of one Fund for shares of
another Fund (subject to receipt of any required state securities law clearances
with respect to certain Funds in the shareholder's state of residence).  An
exchange of shares is treated for federal income tax purposes

                                       47
<PAGE>
 
as a redemption (sale) of shares given in exchange by the shareholder, and an
exchanging shareholder may, therefore, realize a taxable gain or loss in
connection with the exchange. See "Distributions and Taxes" below.

The exchange privilege enables a shareholder to acquire shares in a Fund with
different investment objectives or policies when the shareholder believes that a
shift between Funds is an appropriate investment decision.

Upon receipt of proper instructions and all necessary supporting documents,
shares submitted for exchange are redeemed at the then-current net asset value
and the proceeds are immediately invested, at a price as described above, in
shares of the Fund being acquired.  The Company reserves the right to reject any
exchange request.

As described in the Prospectus, the exchange privilege may be terminated or
revised by the Company.

PURCHASES-IN-KIND

The Funds may, at the sole discretion of the Adviser, accept securities in
exchange for shares of a Fund.  Securities which may be accepted in exchange for
shares of any Fund must: (1) meet the investment objectives and policies of the
Fund; (2) be acquired for investment and not for resale; (3) be liquid
securities which are not restricted as to transfer either by law or liquidity of
market (determined by reference to liquidity policies established by the Board
of Directors); and (4) have a value which is readily ascertainable as evidenced
by, for example, a listing on a recognized stock exchange.

DISTRIBUTIONS AND TAXES

Each of the Funds intends to qualify as a "regulated investment company" under
the Internal Revenue Code of 1986, as amended (the "Internal Revenue Code").  A
Fund that is a regulated investment company and distributes to its shareholders
at least 90% of its taxable net investment income (including, for this purpose,
its net realized short-term capital gains) and 90% of its tax-exempt interest
income (reduced by certain expenses), will not be liable for federal income
taxes to the extent its taxable net investment income and its net realized long-
term and short-term capital gains, if any, are distributed to its shareholders.
However, a Fund will be taxed on that portion of taxable net investment income
and long-term and short-term capital gains that it retains.  Furthermore, a Fund
will be subject to United States corporate income tax (and possibly state or
local income or franchise tax) with respect to such distributed amounts in any
year that it fails to qualify as a regulated investment company or fails to meet
the 90% distribution requirement.

To qualify as a regulated investment company, in addition to the 90%
distribution requirement described above, a Fund must: (a) derive at least 90%
of its gross income from dividends, interest, certain payments with respect to
securities loans and gains from the sale or other disposition of stock or
securities or foreign currencies or other income (including but not limited to
gains from options, futures or forward contracts) derived with respect to its
business in investing in such stock, securities or currencies, and (b) diversify
its holdings so that at the end of each fiscal quarter, (i) at

                                       48
<PAGE>
 
least 50% of the value of the Fund's assets is represented by cash items, U.S.
Government Securities and other securities, limited in respect of any one
issuer, to an amount not greater than 5% of the Fund's total assets and 10% of
the outstanding voting securities of such issuer, and (ii) not more than 25% of
the value of its total assets is invested in the securities of any one issuer
(other than U.S. Government Securities) or in the securities of two or more
issuers (other than U.S. Government Securities) which the Fund controls (i.e.,
holds at least 20% of the combined voting power) and which are engaged in the
same or similar trades or businesses or related trades or businesses.

With respect to the Equity Funds that invest in foreign currency or forward
foreign exchange contracts, Core Fixed Income and Emerging Markets Income, gains
from such foreign currency and forward foreign exchange contracts relating to
investments in stocks, securities or foreign currencies are considered to be
qualifying income for purposes of the 90% gross income test described in clause
(a) above, provided such gains are directly related to the Fund's principal
business of investing in stock or securities.  It is currently unclear, however,
who will be treated as the issuer of certain foreign currency instruments or how
foreign currency contracts will be valued for purposes of the asset
diversification requirements applicable to the Fund described in clause (c)
above.  Until such time as these uncertainties are resolved, each Fund will
utilize the more conservative, or limited, definition or approach with respect
to determining permissible investments in its portfolio.

Investments in foreign currencies, forward contracts, options, futures contracts
and options thereon may subject a Fund to special provisions of the Internal
Revenue Code that may affect the character of gains and losses realized by the
Fund (i.e., may affect whether gains or losses are ordinary or capital), may
accelerate recognition of income to a Fund, and may defer Fund losses.  These
rules also (a) could require a Fund to mark-to-market certain types of the
positions in its portfolio (i.e., treat them as if they had been closed out in a
fully taxable transaction) and (b) may cause the Fund to recognize income
without receiving cash with which to pay dividends or make distributions in
amounts necessary to satisfy the distribution requirements for avoiding income
and excise taxes.

As a general rule, a Fund's gain or loss on a sale or exchange of an investment
will be a long-term capital gain or loss if the Fund has held the investment for
more than one year and will be a short-term capital gain or loss if it has held
the investment for one year or less.  Furthermore, as a general rule, a
shareholder's gain or loss on a sale or redemption of Fund shares will be a
long-term capital gain or loss if the shareholder has held his or her Fund
shares for more than one year and will be a short-term capital gain or loss if
he or she has held his or her Fund shares for one year or less.  For federal,
state and local income tax purposes, an exchange by a shareholder of shares in
one Fund or securities for shares in a Fund will be treated as a taxable sale
for a purchase price equal to the fair market value of the shares received.

Any loss realized on the disposition by a shareholder of its shares in a Fund
will be disallowed to the extent the shares disposed of are replaced with other
Fund shares, including replacement through the reinvesting of dividends and
capital gains distributions in the Fund, within a period (of 61 days) beginning
30 days before and ending 30 days after the disposition of the shares.  In such
a case, the basis of the shares acquired will be increased to reflect the
disallowed loss.  Any loss

                                       49
<PAGE>
 
realized by a shareholder on the sale of a Fund share held by the shareholder
for six months or less will be treated as a long-term capital loss to the extent
of any distributions of capital gain dividends (as defined below) received by
the shareholder with respect to such share.

While only the Equity Funds expect to realize a significant amount of net long-
term capital gains, any such realized gains will be distributed as described in
the Prospectus.  See "Dividends, Distributions and Taxes" in the Prospectus.
Such distributions ("capital gain dividends"), if any, will be taxable to
shareholders as long-term capital gains, regardless of how long a shareholder
has held Fund shares, and will be designated as capital gain dividends in a
written notice mailed to the shareholder after the close of the Fund's prior
taxable year.  A Fund may be subject to taxes in foreign countries in which each
invests.  If such a Fund invests in an entity which is classified as a "passive
foreign investment company" ("PFIC") for U.S. tax purposes, the application of
certain technical tax provisions applying to such companies could result in the
imposition of federal income tax with respect to such investments at the Fund
level which could not be eliminated by distributions to the shareholders of the
Fund.  It is not anticipated that any taxes at the Fund level with respect to
investments in PFICs will be significant.

Under the Internal Revenue Code, a nondeductible excise tax of 4% is imposed on
a Fund to the extent the Fund does not distribute by the end of any calendar
year at least 98% of its ordinary income for that calendar year and at least 98%
of the net amount of its capital gains (both long-term and short-term) for the
one-year period ending on October 31 of such calendar year (or December 31 if
the Fund so elects), plus any undistributed amounts of taxable income for prior
years.  For this purpose, however, any income or gain retained by the Fund that
is subject to corporate income tax will be considered to have been distributed
by year-end.  Each Fund intends to meet these distribution requirements to avoid
the excise tax liability.

Dividends generally are taxable to shareholders at the time they are paid.
However, dividends declared in October, November and December and made to
shareholders of record in such a month are treated as paid and are taxable as of
December 31, provided that the Fund pays the dividend during January of the
following year.

If a shareholder fails to furnish a correct taxpayer identification number,
fails to report fully dividend or interest income, or fails to certify that it
has provided a correct taxpayer identification number and that it is not subject
to "backup withholding," then the shareholder may be subject to a 31% "backup
withholding" tax with respect to: (a) taxable dividends and distributions, and,
(b) the proceeds of any redemptions of Fund shares.  An individual's taxpayer
identification number is his social security number.  The 31% "backup
withholding" tax is not an additional tax and may be credited against a
taxpayer's regular federal income tax liability.

Dividends to shareholders who are non-resident aliens may be subject to a 30%
United States withholding tax under provisions of the Code applicable to foreign
individuals and entities unless a reduced rate of withholding or a withholding
exemption is provided under applicable treaty law.  Non-resident shareholders
should consult their own tax advisers.

The foregoing is a general and abbreviated summary of the applicable provisions
of the Internal Revenue Code and Treasury Regulations presently in effect.  For
the complete provisions, reference

                                       50
<PAGE>
 
should be made to the pertinent Internal Revenue Code sections and the Treasury
Regulations promulgated thereunder. The Internal Revenue Code and these
Regulations are subject to change by legislative or administrative action.

Each shareholder will receive annual information from its Fund regarding the tax
status of Fund distributions.  Shareholders are urged to consult their attorneys
or tax advisers with respect to the applicability of federal, state, local,
estate and gift taxes and non-U.S. taxes to their investment in the Fund.

INVESTMENT RESULTS

From time to time, the Company may quote the performance of a Fund in terms of
yield, actual distributions, total return or capital appreciation in reports or
other communications to shareholders or in other published material.

The Bond Funds may quote a 30-day yield figures which is calculated according to
a formula prescribed by the SEC.  The formula can be expressed as follows:

   YIELD = 2[(a-b) + 1)/6/ - 1]
              ---
              cd
Where:
     a   =    dividends and interest earned during the period.

     b   =    expenses accrued for the period (net of reimbursement).

     c   =    the average daily number of shares outstanding during the period
              that were entitled to receive dividends.

     d   =    the maximum offering price per share on the last day of the
              period. 

For the purpose of determining the interest earned (variable "a" in the formula)
on debt obligations that were purchased by one of the Bond Funds at a discount
or premium, the formula generally calls for amortization of the discount or
premium; the amortization schedule will be adjusted monthly to reflect changes
in the market values of the debt obligations.

The yield of Money Market is its net income expressed in annualized terms.  The
SEC requires by rule that a yield quotation set forth in an advertisement for a
"money market" fund be computed by a standardized method based on a historical
seven calendar day period.  The standardized yield is computed by determining
the net change (exclusive of realized gains and losses and unrealized
appreciation and depreciation) in the value of a hypothetical pre-existing
account having a balance of one share at the beginning of the period, dividing
the net change in account value by the value of the account at the beginning of
the base period return by 365/7.  The determination of net change in account
value reflects the value of additional shares purchased with dividends from the
original share, dividends declared on both the original share and such
additional shares, and all fees that are

                                       51
<PAGE>
 
charged to all shareholder accounts, in proportion to the length of the base
period and the Fund's average account size. Money Market may also calculate its
effective yield by compounding the unannualized base period return (calculated
as described above) by adding 1 to the base period return, raising the sum to a
power equal to 365 divided by 7, and subtracting one.

The yield quoted at any time represents the amount being earned on a current
basis for the indicated period and is a function of the types of instruments in
Money Market, their quality and length of maturity, and the Fund's operating
expenses.  The length of maturity for the Fund is the average dollar weighted
maturity of the Fund.  This means that the Fund has an average maturity of a
stated number of days for all of its issues.  The calculation is weighted by the
relative value of the investment.

Each Bond Fund's and Equity Fund's total return may be calculated on an "average
annual total return" basis, and may also be calculated on an "aggregate total
return" basis, for various periods.  Average annual total return reflects the
average annual percentage change in the value of an investment in a Fund over
the particular measuring period.  Aggregate total return reflects the cumulative
percentage change in value over the measuring period.  Average annual total
return figures provided for the Bond Funds and Equity Funds will be computed
according to a formula prescribed by the SEC.  The formula for an average annual
total return can be expressed as follows:

P(1+T)/n/ ` ERV

Where:

     P     =    hypothetical initial payment of $1,000

     T     =    average annual total return

     n     =    number of years

     ERV        Ending Redeemable Value of a hypothetical $1,000 payment made at
                the beginning of the 1, 5 or 10 year (or other) periods or the
                life of the Fund

The formula for calculating aggregate total return can be expressed as follows:

Aggregate Total Return  [ ( ERV ) - 1 ]
                            ---        
                             P

The calculation of average annual total return and aggregate total return
assumes reinvestment of all income dividends and capital gain distributions on
the reinvestment dates during the period and includes all recurring fees charged
to all shareholder accounts.

The ERV assumes complete redemption of the hypothetical investment at the end of
the measuring period and reflects deduction of all nonrecurring charges at the
end of the measuring period covered by the computation.  A Fund's net investment
income changes in response to fluctuations in interest rates and the expenses of
the Fund.

                                       52
<PAGE>
 
A Fund's performance will vary from time to time depending upon market
conditions, the composition of its portfolio and its operating expenses.
Consequently, any given performance quotation should not be considered
representative of the Fund's performance for any specified period in the future.
In addition, because performance will fluctuate, it may not provide a basis for
comparing an investment in a Fund with certain bank deposits or other
investments that pay a fixed yield or return for a stated period of time.

Investors should recognize that, because the Bond Funds will have a high
component of fixed-income securities, in periods of declining interest rates the
yields of the Bond Funds will tend to be somewhat higher than prevailing market
rates, and in periods of rising interest rates yields will tend to be somewhat
lower.  In addition, when interest rates are falling, the inflow of net new
money to the Bond Funds from the continuous sale of shares will likely be
invested in portfolio instruments producing lower yields than the balance of the
Bond Funds' securities, thereby reducing the current yields of the Bond Funds.
In periods of rising interest rates, the opposite can be expected to occur.

Comparative performance information may be used from time to time in publishing
information about the Company's shares, including data from Lipper Analytical
Services, Inc., CDA Technologies, Inc., or similar independent services which
monitor the performance of mutual funds or with other appropriate indexes of
investment securities.  The performance information may also include evaluations
of the Funds published by nationally recognized ranking services and by
financial publications that are nationally recognized, such as Business Week,
Forbes, Fortune, Institutional Investor, Money and The Wall Street Journal.  A
Fund may compare its performance to other investments or relevant indexes
including, but not limited to, the following:  High Yield Bond -- First Boston

ORGANIZATION, SHARES AND VOTING RIGHTS

The Company was incorporated as a Maryland corporation on September 15, 1992 and
is registered with the Securities and Exchange Commission as an open-end,
management investment company.  The Company has acknowledged that the name "TCW"
is owned by The TCW Group, Inc. ("TCW"), the parent of the Adviser.  The Company
has agreed to change its name and the name of the Funds at the request of TCW if
any advisory agreement into which TCW or any of its affiliates and the Company
may enter is terminated.

The Fund offers two classes of shares: the Institutional Class shares and the
Class N shares.  The Institutional Class shares are offered at the current net
asset value.  The Class N shares are also offered at the current net asset
value, but will be subject to distribution or service fees imposed under the
Distribution Plan.  Shares of each class of a Fund represents an equal
proportionate share in the assets, liabilities, income and expenses of that
Fund and, generally, have identical voting, dividend, liquidation, and other
rights, other than the payment of distribution fees imposed under the
Distribution Plan.  All shares issued will be fully paid and nonassessable and
will have no preemptive or conversion rights.  Each share has one vote and
fractional shares have fractional votes.  As a Maryland corporation, the Company
is not required to hold an annual shareholder meeting in any year in which the
selection of directors is not required to be acted on under the 1940 Act.
Shareholder approval will be sought only for certain changes in the operation of
the Funds and for the election of directors under certain circumstances.
Directors may be removed by a majority of all votes entitled to be cast by
shareholders at a meeting.  A special meeting of the shareholders will be called
to elect or remove directors if requested by the holders of ten percent of the
Company's outstanding shares.  All shareholders of the Funds will vote together
with all other shareholders of the Funds and with all shareholders of all other
funds that the Company may form in the future on all matters affecting the
Company, including the election or removal of directors.  For matters where the
interests of separate Funds or classes of a Fund are not identical, the matter
will be voted on separately by each affected Fund or class.  For matters
affecting only one Fund or class of a Fund, only the shareholders of that Fund
or class will be entitled to vote thereon.  Voting is not cumulative.  Upon
request in writing by ten or more shareholders who have been shareholders of
record for at least six months and hold at least the lesser of shares having a
net asset value of $25,000 or one percent of all outstanding shares, the Company
will provide the requesting shareholders either access to the names and
addresses of all shareholders of record or information as to the approximate
number of shareholders of record and the approximate cost of mailing any
proposed communication to them.  If the Company elects the latter procedure, and
the requesting shareholders tender material for mailing together with the
reasonable expenses of the mailing, the Company will either mail the material as
requested or submit the material to the Securities and Exchange Commission for a
determination that the mailing of the material would be inappropriate.

                                   APPENDIX A

Description of S&P and Moody's Ratings

S&P

AAA - Debt rated AAA has the highest rating assigned by S&P.  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.

Fixed income securities rated AAA, AA, A and BBB are considered investment
grade.

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 or 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 - The rating CC is typically applied to debt subordinated to senior debt that
is assigned an actual or implied CCC rating.

                                      A-1
<PAGE>
 
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 also will be used upon the
filing of a bankruptcy petition if  debt service payments are jeopardized.

Plus (+) or Minus (-) - 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
categories.

Moody's

Aaa - Bonds which are rated Aaa are judged to be 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 as can be visualized are most unlikely to impair
the fundamentally strong position of such issues.

Aa - Bonds which are rated Aa are judged to be of 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 there may be other elements present which make
the long-term risks appear somewhat larger than in Aaa securities.

A - Bonds which are 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 which are rated Baa are considered as 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.

Fixed income securities which are rated Aaa, Aa, A and Baa are considered
investment grade.

Ba - Bonds which are rated Ba are judged to have speculative elements; their
future cannot be considered as well assured.  Often the protection of interest
and principal payments may be very moderate and thereby not well safeguarded
during other good and bad times over the future.  Uncertainty of position
characterizes bonds in this class.

                                      A-2
<PAGE>
 
B - Bonds which are rated B generally lack characteristics of the desirable
investment.  Assurance of interest and principal payments or of maintenance of
other terms of the contract over any long period of time may be small.

Caa - Bonds which are rated Caa are of poor standing.  Such issues may be in
default or there may be present elements of danger with respect to principal or
interest.

Ca - Bonds which are rated Ca represent obligations which are speculative in a
high degree.  Such issues are often in default or have other marked
shortcomings.

C - Bonds which are rated C are the lowest rated class of bonds and issues so
rated can be regarded as having extremely poor prospects of ever attaining any
real investment standing.

Moody's applies the numerical modifiers 1, 2 and 3 to each generic rating
classification from Aa through B.  The modifier 1 indicates that the issue 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.

ITEM 24.  Persons Controlled by or Under Common Control with the Registrant
          -----------------------------------------------------------------

TCW Funds Management, Inc. (the "Adviser") is a 100% owned subsidiary of The TCW
Group, Inc. (formerly TCW Management Company), a Nevada corporation.  Robert A.
Day, who is Chairman of the Board of Directors of the Adviser, may be deemed to
be a control person of the Adviser by virtue of the aggregate ownership of Mr.
Day and his family of more than 25% of the outstanding voting stock of The TCW
Group, Inc. (formerly TCW Management Company).

ITEM 25.  Indemnification
          ---------------

Under Article Eighth, Section (9) of the Company's Articles of Incorporation,
directors and officers of the Company will be indemnified, and will be advanced
expenses, to the fullest extent permitted by Maryland law, but not in violation
of Section 17(i) of the Investment Company Act of 1940.  Such indemnification
rights are also limited by Article 9.01 of the Company's Bylaws.

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

No. 801-29075) filed with the Commission, which is hereby incorporated by
reference, for the activities and affiliations of the officers and directors of

knowledge of Registrant, none of the directors or executive officers of the
Investment Advisor is or has been at any time during the past two fiscal years
engaged in any other business, profession, vocation or employment of a
substantial nature.   In addition to the Funds, the Adviser serves as investment
