TCW/DW Balanced Fund (the "Fund") is an open-end, diversified management
investment company, whose investment objective is to achieve high total return
through a combination of income and capital appreciation. The Fund seeks to
achieve its investment objective by investing in a diversified portfolio of
common stocks and investment grade fixed-income securities. See "Investment
Objective and Policies."
 
   
The Fund offers four classes of shares (each, a "Class"), each with a different
combination of sales charges, ongoing fees and other features. The different
distribution arrangements permit an investor to choose the method of purchasing
shares that the investor believes is most beneficial given the amount of the
purchase, the length of time the investor expects to hold the shares and other
relevant circumstances. See "Purchase of Fund Shares -- Alternative Purchase
Arrangements."
    
 
   
This Prospectus sets forth concisely the information you should know before

Fund ("Balanced Growth"), pursuant to which the assets of the Fund would be
combined with those of Balanced Growth and shareholders of the Fund would become
shareholders of Balanced Growth receiving shares of Balanced Growth equal to the
value of their holdings in the Fund (the "Reorganization"). The Reorganization
is subject to the approval of shareholders of the Fund. See "The Fund and its
Management."

ALTERNATIVE        Four classes of shares are offered:
PURCHASE           - Class A shares are offered with a front-end sales charge, starting at 5.25%
ARRANGEMENTS       and reduced for larger purchases. Investments of $1 million or more (and
                   investments by certain other limited categories of investors) are not subject
                   to any sales charge at the time of purchase but a contingent deferred sales
                   charge ("CDSC") of 1.0% may be imposed on redemptions within one year of
                   purchase. The Fund is authorized to reimburse the Distributor for specific
                   expenses incurred in promoting the distribution of the Fund's Class A shares
                   and servicing shareholder accounts pursuant to the Fund's 12b-1 Plan.
                   Reimbursement may in no event exceed an amount equal to payments at an annual
                   rate of 0.25% of average daily net assets of the Class (see pages 17, 20 and
                   25).
 
                   - Class B shares are offered without a front-end sales charge, but will in
                   most cases be subject to a CDSC (scaled down from 5.0% to 1.0%) if redeemed
                   within six years after purchase. The CDSC will be imposed on any redemption of
                   shares if after such redemption the aggregate current value of a Class B
                   account with the Fund falls below the aggregate amount of the investor's
                   purchase payments made during the six years preceding the redemption. A
                   different CDSC schedule applies to investments by certain qualified plans.
                   Class B shares are also subject to a 12b-1 fee assessed at the annual rate of
                   1.0% of the average daily net assets of Class B. Shares of the Fund held prior
                   to July 28, 1997 which were acquired in exchange for shares of TCW/DW Funds
                   sold with a CDSC, including shares acquired through reinvestment of dividends
                   and distributions thereon, have been designated Class B shares. Shares held
                   before May 1, 1997 that have been designated Class B shares will convert to
                   Class A shares in May, 2007. In all other instances, Class B shares convert to
                   Class A shares approximately ten years after the date of the original purchase
                   (see pages 17, 23 and 25).
 
                   - Class C shares are offered without a front-end sales charge, but will in
                   most cases be subject to a CDSC of 1.0% if redeemed within one year after
                   purchase. The Fund is authorized to reimburse the Distributor for specific
                   expenses incurred in promoting the distribution of the Fund's Class C shares
                   and servicing shareholder accounts pursuant to the Fund's 12b-1 Plan.
                   Reimbursement may in no event exceed an amount equal to payments at an annual
                   rate of 1.0% of average daily net assets of the Class. All shares of the Fund
                   held prior to July 28, 1997 (other than shares which were acquired in exchange
                   for shares of TCW/DW Funds offered with a CDSC and shares acquired through
                   reinvestment of dividends and distributions thereon) have been designated
                   Class C shares. Shares held before July 28, 1997 that have been designated
                   Class C shares are not subject to the 1.0% CDSC (see pages 17 and 25).
 
                   - Class D shares are offered only to investors meeting an initial investment
                   minimum of $5 million and to certain other limited categories of investors.
                   Class D shares are offered without a front-end sales charge or CDSC and are
                   not subject to any 12b-1 fee (see pages 17 and 25).

DIVIDENDS          Income dividends are intended to be paid quarterly. Capital gains
AND                distributions, if any, will be paid at least annually. The Fund may, however,
CAPITAL GAINS      determine to retain all or part of any net long- term capital gains in any
DISTRIBUTIONS      year for reinvestment. Dividends and capital gains distributions paid on
                   shares of a Class are automatically reinvested in additional shares of the
                   same Class at net asset value unless the shareholder elects to receive cash.
                   Shares acquired by dividend and distribution reinvestment will not be subject
                   to any sales charge or CDSC (see pages 27 and 31).

REDEMPTION         Shares are redeemable by the shareholder at net asset value less any
                   applicable CDSC on Class A, Class B or Class C shares. An account may be
                   involuntarily redeemed if the total value of the account is less than $100 or,
                   if the account was opened through EasyInvest-SM-, if after twelve months the
                   shareholder has invested less than $1,000 in the account (see page 30).
- ------------------------------------------------------------------------------------------------
RISK               The net asset value of the Fund's shares will fluctuate with changes in the
CONSIDERATIONS     market value of the Fund's portfolio securities. The Fund may invest a portion
                   of its assets in mortgage-backed and asset-backed securities, including up to
                   5% of its net assets in collateralized mortgage obligations. Mortgage-backed
                   securities are subject to special risks including prepayments or refinancings
                   of the assets underlying such securities which may have an impact on the yield
                   and the net asset value of the Fund's shares (see pages 13-14). The Fund may
                   invest up to 25% of its total assets in non-dollar denominated foreign
                   securities, which may entail special risks (see pages 12-13). The Fund also
                   may enter into reverse repurchase agreements and dollar rolls, may purchase
                   securities on a when-issued, delayed delivery or "when, as and if issued"
                   basis and may enter into forward foreign currency exchange contracts, which
                   involve certain additional risks (see pages 14-16).

<FN>
- ------------
(1)  Reduced for purchases of $25,000 and over (see "Purchase of Fund Shares --
     Initial Sales Charge Alternative -- Class A Shares").
(2)  Investments that are not subject to any sales charge at the time of
     purchase are subject to a CDSC of 1.00% that will be imposed on redemptions
     made within one year after purchase, except for certain specific
     circumstances (see "Purchase of Fund Shares -- Initial Sales Charge
     Alternative -- Class A Shares").
(3)  The CDSC is scaled down to 1.00% during the sixth year, reaching zero
     thereafter.
(4)  Only applicable to redemptions made within one year after purchase (see
     "Purchase of Fund Shares -- Level Load Alternative -- Class C Shares").
(5)  The 12b-1 fee is accrued daily and payable monthly. The entire 12b-1 fee
     payable by Class A and a portion of the 12b-1 fee payable by each of Class
     B and Class C equal to 0.25% of the average daily net assets of the Class
     are currently each characterized as a service fee within the meaning of
     National Association of Securities Dealers, Inc. ("NASD") guidelines and
     are payments made for personal service and/or maintenance of shareholder
     accounts. The remainder of the 12b-1 fee, if any, is an asset-based sales
     charge, and is a distribution fee paid to the Distributor to compensate it
     for the services provided and the expenses borne by the Distributor and
     others in the distribution of the Fund's shares (see "Purchase of Fund
     Shares -- Plan of Distribution").
(6)  Upon conversion of Class B shares to Class A shares, such shares will be
     subject to the lower 12b-1 fee applicable to Class A shares. No sales
     charge is imposed at the time of conversion of Class B shares to Class A
     shares. Class C shares do not have a conversion feature and, therefore, are
     subject to an ongoing 1.00% distribution fee (see "Purchase of Fund Shares
     -- Alternative Purchase Arrangements").
(7)  There were no outstanding shares of Class A, Class B or Class D prior to
     July 28, 1997. Accordingly, "Total Fund Operating Expenses," as shown above
     with respect to those Classes, are estimates based upon the sum of 12b-1
     Fees, Management Fees and estimated "Other Expenses."

    The purpose of this table is to assist the investor in understanding the
various costs and expenses that an investor in the Fund will bear directly or
indirectly. For a more complete description of these costs and expenses, see
"The Fund and its Management" and "Purchase of Fund Shares -- Plan of
Distribution" and "Repurchases and Redemptions."
 
    Long-term shareholders of Class B and Class C may pay more in sales charges,
including distribution fees, than the economic equivalent of the maximum
front-end sales charges permitted by the NASD.

THE FUND AND ITS MANAGEMENT
- --------------------------------------------------------------------------------
 
    TCW/DW Balanced Fund (the "Fund") is an open-end, diversified management
investment company. The Fund is a trust of the type commonly known as a
"Massachusetts business trust" and was organized under the laws of Massachusetts
on March 2, 1993.
 
    Dean Witter Services Company Inc. (the "Manager"), whose address is Two
World Trade Center, New York, New York 10048, is the Fund's Manager. The Manager
is a wholly-owned subsidiary of Dean Witter InterCapital Inc. ("InterCapital").
InterCapital is a wholly-owned subsidiary of Morgan Stanley, Dean Witter,
Discover & Co., a preeminent global financial services firm that maintains
leading market positions in each of its three primary businesses -- securities,
asset management and credit services.
 
   
    The Manager acts as manager to thirteen other TCW/DW Funds. The Manager and
InterCapital act in various investment management, advisory, management and
administrative capacities to a total of 100 investment companies, thirty of
which are listed on the New York Stock Exchange, with combined assets of
approximately $97.0 billion as of October 31, 1997. InterCapital also manages
and advises portfolios of pension plans, other institutions and individuals
which aggregated approximately $3.7 billion at such date.
    
 
    The Fund has retained the Manager to manage its business affairs, supervise
its overall day-to-day operations (other than providing investment advice) and
provide all administrative services.
 
   
    TCW Funds Management, Inc. (the "Adviser"), whose address is 865 South
Figueroa Street, Suite 1800, Los Angeles, California 90017, is the Fund's
investment adviser. The Adviser was organized in 1987 as a wholly-owned
subsidiary of The TCW Group, Inc. ("TCW"), whose subsidiaries, including Trust
Company of the West and TCW Asset Management Company, provide a variety of
trust, investment management and investment advisory services. Robert A. Day,
who is Chairman of the Board of Directors of TCW, may be deemed to be a control
person of the Adviser by virtue of the aggregate ownership by Mr. Day and his
family of more than 25% of the outstanding voting stock of TCW. The Adviser
serves as investment adviser to thirteen other TCW/DW Funds in addition to the
Fund. As of October 31, 1997, the Adviser and its affiliated companies had
approximately $50 billion under management or committed to management, primarily
from institutional investors.
    
 
    The Fund has retained the Adviser to invest the Fund's assets.
 
    The Fund's Trustees review the various services provided by the Manager and
the Adviser to ensure that the Fund's general investment policies and programs
are being properly carried out and that administrative services are being
provided to the Fund in a satisfactory manner.
 
    As full compensation for the services and facilities furnished to the Fund
and for expenses of the Fund assumed by the Manager, the Fund pays the Manager
monthly compensation calculated daily by applying the annual rate of 0.45% to
the Fund's net assets. As compensation for its investment advisory services, the
Fund pays the Adviser monthly compensation calculated daily by applying an
annual rate of 0.30% to the Fund's net assets. The total of the management and
advisory fees paid by the Fund is higher than the advisory fees paid by most
other investment companies.
 
   
    For the fiscal year ended September 30, 1997, the Fund accrued to the
Manager and the Adviser total compensation amounting to 0.45% and 0.30%,
respectively, of the Fund's average daily net assets and total expenses of Class
C amounted to 2.08% of the average daily net assets of Class C. Shares of Class
A, Class B and Class D were first issued on July 28, 1997. The expenses of the
Fund include: the fees of the Manager and the Adviser; the fee pursuant to the
Plan of Distribution (see "Purchase of Fund Shares"); taxes; transfer agent,
custodian and auditing fees; certain legal fees; and printing and other expenses
relating to the Fund's operations which are not expressly assumed by the Manager
or the Adviser under their respective Agreements with the Fund.
    
 
   
    On November 6, 1997, the Board of Trustees of the Fund approved an Agreement
and Plan of
    
 
                                       10

Reorganization by and between the Fund and Dean Witter Balanced Growth Fund
("Balanced Growth"), pursuant to which the assets of the Fund would be combined
with those of Balanced Growth and shareholders of the Fund would become
shareholders of Balanced Growth receiving shares of Balanced Growth equal to the
value of their holdings in the Fund (the "Reorganization"). The Reorganization
is subject to the approval of shareholders of the Fund. A proxy statement
formally detailing the proposal and the reasons for the Trustees' action, as
well as information concerning Balanced Growth, will be distributed to
shareholders of the Fund who hold shares of the Fund as of the record date for
the shareholder meeting.
    
 
INVESTMENT OBJECTIVE AND POLICIES
- --------------------------------------------------------------------------------
 
    The investment objective of the Fund is to achieve high total return through
a combination of income and capital appreciation. This objective is fundamental
and may not be changed without shareholder approval. There is no assurance that
the objective will be achieved.
 
    The Fund seeks to obtain its objective by investing in a diversified
portfolio of common stocks and investment grade fixed-income securities. The
percentage of assets allocated between equity and fixed-income securities will
vary from time to time depending on the judgment of the Adviser as to general
economic and market conditions, changes in fiscal or monetary policies and
trends in yields and interest rates. However, under normal circumstances, it is
expected that common stocks will represent approximately 60-70% of the Fund's
total assets. In addition, the Fund under normal circumstances will maintain at
least 25% of its total assets in fixed-income securities.
 
    The investments in the equity portion of the Fund's portfolio are determined
pursuant to a "top down" investment process ranging from the overall economic
outlook, to the development of industry/sector preferences, and, last, to
specific stock selections. The following disciplines generally apply with regard
to stock selection of the equity component of the Fund's portfolio: (i) no
single issuer's equity securities will represent at the time of purchase more
than 5% of the Fund's total assets; and (ii) at least 95% of the companies
represented will have minimum market capitalizations at the time of purchase in
excess of $1 billion. Subject to the Fund's investment objective, the Adviser
may modify the foregoing disciplines without notice.
 
    The fixed-income portion of the Fund's portfolio may consist of securities
issued or guaranteed by the U.S. Government (Treasury bills, notes and bonds),
investment grade corporate debt securities (including convertible securities),
mortgage-backed and asset-backed securities and money market securities (as
described below). All fixed-income securities in which the Fund invests will be
either issued or guaranteed by the U.S. Government, its agencies or
instrumentalities or rated at least BBB by Standard & Poor's Corporation ("S&P")
or Baa by Moody's Investors Service, Inc. ("Moody's") or, if not rated,
determined by the Adviser to be of comparable quality.
 
    Under normal circumstances, no more than 10% of the fixed-income portion of
the Fund's portfolio will be rated BBB by S&P or Baa by Moody's. Fixed-income
securities rated BBB by S&P or Baa by Moody's, which generally are regarded as
having an adequate capacity to pay interest and repay principal, have
speculative characteristics. Thus, changes in economic conditions are more
likely to lead to a weakened capacity to make principal and interest payments
than is the case with respect to higher rated securities. If a fixed-income
security held by the Fund is rated BBB or Baa and is subsequently downgraded by
a rating agency, the Fund will retain such security in its portfolio until the
Adviser determines that it is practicable to sell the security without undue
market or tax consequences to the Fund. In the event that such downgraded
securities constitute 5% or more of the Fund's net assets, the Adviser will seek
to sell immediately sufficient securities to reduce the total to below 5%. A
description of fixed-income securities ratings is contained in the Appendix to
the Statement of Additional Information.
 
                                       11
<PAGE>
PORTFOLIO CHARACTERISTICS
 
    Although the Fund will invest primarily in equity securities and
fixed-income corporate debt securities, it may engage to a limited extent in
certain specialized investments and investment techniques which are described
below.
 
    MORTGAGE-BACKED AND ASSET-BACKED SECURITIES.  As stated above, the Fund may
invest in fixed-rate and adjustable-rate mortgage-backed securities
("Mortgage-Backed Securities").
 
    There are currently three basic types of Mortgage-Backed Securities: (i)
those issued or guaranteed by the United States Government or one of its
agencies or instrumentalities, such as the Government National Mortgage
Association ("GNMA"), the Federal National Mortgage Association ("FNMA") and the
Federal Home Loan Mortgage Corporation ("FHLMC") (securities issued by GNMA, but
not those issued by FNMA or FHLMC, are backed by the "full faith and credit" of
the United States); (ii) those issued by private issuers that represent an
interest in or are collateralized by Mortgage-Backed Securities issued or
guaranteed by the United States Government or one of its agencies or
instrumentalities; and (iii) those issued by private issuers that represent an
interest in or are collateralized by whole mortgage loans or Mortgage-Backed
Securities without a government guarantee but usually having some form of
private credit enhancement. The Fund may also invest in adjustable-rate mortgage
securities, which are pass-through mortgage securities collateralized by
mortgages with adjustable rather than fixed rates.
 
    The Fund may also invest up to 5% of its net assets in collateralized
mortgage obligations ("CMOs"), which 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. Types
of CMOs in which the Fund may invest may be issued either by the U.S. Government
or by private issuers.
 
    The Fund may also invest in other asset-backed securities ("Asset-Backed
Securities"), which involve use of the securitization techniques utilized in
connection with Mortgage-Backed Securities in connection with other assets,
primarily automobile and credit card receivables and home equity loans.
 
    CONVERTIBLE SECURITIES.  A convertible security is a bond, debenture, note,
preferred stock or other security that may be converted into or exchanged for a
prescribed amount of common stock of the same or a different issuer within a
particular period of time at a specified price or based on a specified formula.
Convertible securities rank senior to common stocks in a corporation's capital
structure and, therefore, entail less risk than the corporation's common stock.
The value of a convertible security is a function of its "investment value" (its
value as if it did not have a conversion privilege), and its "conversion value"
(the security's worth if it were to be exchanged for the underlying security, at
market value, pursuant to its conversion privilege).
 
    To the extent that a convertible security's investment value is greater than
its conversion value, its price will be primarily a reflection of such
investment value and its price will be likely to increase when interest rates
fall and decrease when interest rates rise, as with a fixed-income security (the
credit standing of the issuer and other factors may also have an effect on the
convertible security's value). If the conversion value exceeds the investment
value, the price of the convertible security will rise above its investment
value and, in addition, may sell at some premium over its conversion value.
(This premium represents the price investors are willing to pay for the
privilege of purchasing a fixed-income security with a possibility of capital
appreciation due to the conversion privilege.) At such times the price of the
convertible security will tend to fluctuate directly with the price of the
underlying equity security.
 
SPECIAL RISK CONSIDERATIONS
 
   
    The net asset value of the Fund's shares will fluctuate with changes in the
market value of the Fund's portfolio securities. The market value of the Fund's
portfolio securities will increase or decrease due to a variety of economic,
market and political factors, including movements in interest rates, which
cannot be predicted. The Fund's yield will also vary based on the yield of the
Fund's portfolio securities.
    
 
                                       12
<PAGE>
    FOREIGN SECURITIES.  The Fund may invest in securities of foreign companies.
The Fund will not invest more than 25% of the value of its total assets, at the
time of purchase, in non-dollar denominated foreign securities (other than
securities of Canadian issuers registered under the Securities Exchange Act of
1934 or American Depository Receipts, on which there is no such limit). The
Fund's investments in unlisted foreign securities are subject to the Fund's
overall policy limiting its investment in illiquid securities to 15% or less of
its net assets. The Fund currently does not intend to invest more than 25% of
its total assets in the securities of issuers in any one country outside the
United States.
 
    Foreign securities investments may be affected by changes in currency rates
or exchange control regulations, changes in governmental administration or
economic or monetary policy (in the United States and abroad) or changed
circumstances in dealings between nations. Fluctuations in the relative rates of
exchange between the currencies of different nations will affect the value of
the Fund's investments denominated in foreign currency. Changes in foreign
currency exchange rates relative to the U.S. dollar will affect the U.S. dollar
value of the Fund's assets denominated in that currency and thereby impact upon
the Fund's total return on such assets.
 
    Investments in foreign securities will also occasion risks relating to
political and economic developments abroad, including the possibility of
expropriations or confiscatory taxation, limitations on the use or transfer of
Fund assets and any effects of foreign social, economic or political
instability. Foreign companies are not subject to the regulatory requirements of
U.S. companies and, as such, there may be less publicly available information
about such companies. Moreover, foreign companies are not subject to uniform
accounting, auditing and financial reporting standards and requirements
comparable to those applicable to U.S. companies.
 
    Securities of foreign issuers may be less liquid than comparable securities
of U.S. issuers and, as such, their price changes may be more volatile.
Furthermore, foreign exchanges and broker-dealers are generally subject to less
government and exchange scrutiny and regulation than their American
counterparts. Brokerage commissions, dealer concessions and other transaction
costs may be higher on foreign markets than in the U.S. In addition, differences
in clearance and settlement procedures on foreign markets may occasion delays in
settlements of the Fund's trades effected in such markets. As such, the
inability to dispose of portfolio securities due to settlement delays could
result in losses to the Fund due to subsequent declines in value of such
securities and the inability of the Fund to make intended security purchases due
to settlement problems could result in a failure of the Fund to make potentially
advantageous investments.
 
    The Fund may also invest up to 5% of its net assets in a type of Mexican
government money market securities known as Cetes, which are peso-denominated
discount debt securities having maturities of one year or less that are sold
through auctions regulated by Banco de Mexico. The Fund will invest in Cetes
only if they meet the rating standards for the fixed-income portion of the
Fund's portfolio.
 
    MORTGAGE-BACKED AND ASSET-BACKED SECURITIES.  All fixed-income securities
are subject to two types of risks: the credit risk and the interest rate risk.
The credit risk relates to the ability of the issuer to meet interest or
principal payments or both as they come due. Generally, higher yielding
fixed-income securities are subject to a credit risk to a greater extent than
lower yielding fixed-income securities. The interest rate risk refers to the
fluctuations in the net asset value of any portfolio of fixed-income securities
resulting from the inverse relationship between price and yield of fixed-income
securities; that is, when the general level of interest rates rises, the prices
of outstanding fixed-income securities decline, and when interest rates fall,
prices rise.
 
    Mortgage-Backed and Asset-Backed Securities have certain different
characteristics than traditional debt securities. Among the major differences
are that interest and principal payments are made more frequently, usually
monthly, and that principal may be prepaid at any time because the underlying
mortgage loans or other assets generally may be prepaid at any time. As a
result, if the Fund purchases such a security at a premium, a prepayment rate
that is faster than expected may reduce yield to maturity, while a prepayment
rate that is slower than expected may have the
 
                                       13
<PAGE>
opposite effect of increasing yield to maturity. Alternatively, if the Fund
purchases these securities at a discount, faster than expected prepayments will
increase, while slower than expected prepayments may reduce, yield to maturity.
 
    Mortgage-Backed and Asset-Backed Securities, like all fixed income
securities, generally decrease in value as a result of increases in interest
rates. In addition, although generally the value of fixed-income securities
increases during periods of falling interest rates and, as stated above,
decreases during periods of rising interest rates, as a result of prepayments
and other factors, this is not always the case with respect to Mortgage-Backed
and Asset-Backed Securities.
 
    Although the extent of prepayments on a pool of mortgage loans depends on
various economic and other factors, as a general rule prepayments on fixed rate
mortgage loans will increase during a period of falling interest rates and
decrease during a period of rising interest rates. Accordingly, amounts
available for reinvestment by the Fund are likely to be greater during a period
of declining interest rates and, as a result, likely to be reinvested at lower
interest rates than during a period of rising interest rates. Mortgage-Backed
Securities generally decrease in value as a result of increases in interest
rates and may benefit less than other fixed-income securities from declining
interest rates because of the risk of prepayment.
 
    Asset-Backed Securities involve certain risks that are not posed by
Mortgage-Backed Securities, resulting mainly from the fact that Asset-Backed
Securities do not usually contain the complete benefit of a security interest in
the related collateral. For example, credit card receivables generally are
unsecured and the debtors are entitled to the protection of a number of state
and federal consumer credit laws, some of which may reduce the ability to obtain
full payment. In the case  of automobile receivables, due to various legal and
economic factors, proceeds from repossessed collateral may not always be
sufficient to support payments on these securities.
 
    There are certain risks associated specifically with CMOs, in which the Fund
may invest up to 5% of its net assets. CMOs issued by private entities are not
U.S. Government securities 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. Also, a number of different factors, including the extent of prepayment
of principal of the collateralized mortgage obligations, affect the availability
of cash for principal payments by the CMO issuer on any payment date and,
accordingly, affect the timing of principal payments on each CMO class. In
addition, CMO classes with higher yields tend to be more volatile with respect
to cash flow of the underlying mortgages; as a result, the market prices of
those classes tend to be more volatile.
 
    The risks of other investment techniques which may be utilized by the Fund
are described under "Other Investment Policies" below.
 
OTHER INVESTMENT POLICIES
 
    As stated above, the Fund may invest in money market instruments, which are
short-term (maturities of up to thirteen months) fixed-income securities issued
by private and governmental institutions. Money market instruments in which the
Fund may invest are securities issued or guaranteed by the U.S. Government or
its agencies (Treasury bills, notes and bonds); obligations of banks subject to
regulation by the U.S. Government and having total assets of $1 billion or more;
Eurodollar certificates of deposit; obligations of savings banks and savings and
loan associations having total assets of $1 billion or more; fully insured
certificates of deposit; and commercial paper rated within the two highest
grades by Moody's or S&P or, if not rated, issued by a company having an
outstanding debt issue rated AAA by S&P or Aaa by Moody's.
 
    REPURCHASE AGREEMENTS.  The Fund may enter into repurchase agreements, which
may be viewed as a type of secured lending by the Fund, and which typically
involve the acquisition by the Fund of debt securities from a selling financial
institution such as a bank, savings and loan association or broker-dealer. The
agreement provides that the Fund will sell back to the institution, and that the
institution will repurchase, the underlying security at a specified price and at
a fixed time in
 
                                       14
<PAGE>
the future, usually not more than seven days from the date of purchase. While
repurchase agreements involve certain risks not associated with direct
investments in debt securities, including the risks of default or bankruptcy of
the selling financial institution, the Fund follows procedures designed to
minimize such risks. These procedures include effecting repurchase transactions
only with large, well-capitalized and well-established financial institutions
and maintaining adequate collateralization.
 
    REVERSE REPURCHASE AGREEMENTS AND DOLLAR ROLLS.  The Fund may also use
reverse repurchase agreements and dollar rolls with respect to up to 5% of its
total assets as part of its investment strategy. Reverse repurchase agreements
involve sales by the Fund of portfolio assets concurrently with an agreement by
the Fund to repurchase the same assets at a later date at a fixed price. The
Fund also may enter into dollar rolls in which the Fund sells securities for
delivery in the current month and simultaneously contracts to repurchase
substantially similar (same type and coupon) securities on a specified future
date.
 
    Reverse repurchase agreements and dollar rolls involve the risk that the
market value of the securities the 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 dollar roll files for
bankruptcy or becomes insolvent, the Fund's use of the 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 dollar rolls are speculative techniques
involving leverage, and are considered borrowings by the Fund.
 
    WHEN-ISSUED AND DELAYED DELIVERY SECURITIES AND FORWARD COMMITMENTS.  From
time to time, in the ordinary course of business, the Fund may purchase
securities on a when-issued or delayed delivery basis or 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. There is no overall
limit on the percentage of the Fund's assets which may be committed to the
purchase of securities on a when-issued, delayed delivery or forward commitment
basis. An increase in the percentage of the Fund's assets committed to the
purchase of securities on a when-issued, delayed delivery or forward commitment
basis may increase the volatility of the Fund's net asset value.
 
    WHEN, AS AND IF ISSUED SECURITIES.  The Fund 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. If the
anticipated event does not occur and the securities are not issued, the Fund
will have lost an investment opportunity. There is no overall limit on the
percentage of the Fund's assets which may be committed to the purchase of
securities on a "when, as and if issued" basis. 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 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.
 
    ZERO COUPON SECURITIES.  A portion of the fixed-income securities purchased
by the Fund may be zero coupon securities. Such securities are purchased at a
discount from their face amount, giving the purchaser the right to receive their
full value at maturity. The interest earned on such securities is, implicitly,
automatically compounded and paid out at maturity. While such compounding at a
constant rate eliminates the risk of receiving lower yields upon reinvestment of
interest if prevailing interest rates decline, the owner of a zero coupon
security will be unable to participate in higher yields upon reinvestment of
interest received on interest-paying securities if prevailing interest rates
rise.
 
    A zero coupon security pays no interest to its holder during its life.
Therefore, to the extent the Fund invests in zero coupon securities, it will not
receive current cash available for distribution to shareholders. In addition,
zero coupon securities are subject to substantially greater price fluctuations
during periods of changing prevailing interest rates than are comparable
securities which pay interest on a current basis.
 
                                       15
<PAGE>
Current federal tax law requires that a holder (such as the Fund) of a zero
coupon security accrue a portion of the discount at which the security was
purchased as income each year even though the Fund receives no interest payments
in cash on the security during the year.
 
    PRIVATE PLACEMENTS.  The Fund may invest up to 5% of its total assets 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. (Securities eligible for
resale pursuant to Rule 144A under the Securities Act, and determined to be
liquid pursuant to the procedures discussed in the following paragraph, are not
subject to the foregoing restriction.) These securities are generally referred
to as private placements or restricted securities. Limitations on the resale of
such securities may have an adverse effect on their marketability, and may
prevent the Fund from disposing of them promptly at reasonable prices. The 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 adopted Rule 144A under the
Securities Act, which permits the Fund to sell restricted securities to
qualified institutional buyers without limitation. The Adviser, pursuant to
procedures adopted by the Trustees of the Fund, will make a determination as to
the liquidity of each restricted security purchased by the Fund. If a restricted
security is determined to be "liquid," such security will not be included within
the category "illiquid securities," which under current policy may not exceed
15% of the Fund's net assets. However, investing in Rule 144A Securities could
have the effect of increasing the level of Fund illiquidity to the extent the
Fund, at a particular point in time, may be unable to find qualified
institutional buyers interested in purchasing such securities.
 
    FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS.  The Fund may enter into
forward foreign currency exchange contracts ("forward contracts") in connection
with its foreign securities investments.
 
    A forward contract involves an obligation to purchase or sell a currency at
a future date, which may be any fixed number of days from the date of the
contract agreed upon by the parties, at a price set at the time of the contract.
The Fund may enter into forward contracts as a hedge against fluctuations in
future foreign exchange rates.
 
    The Fund will enter into forward contracts under various circumstances. When
the Fund enters into a contract for the purchase or sale of a security
denominated in a foreign currency, it may, for example, desire to "lock in" the
price of the security in U.S. dollars or some other foreign currency which the
Fund is temporarily holding in its portfolio.
 
    At other times, when, for example, the Adviser believes that the currency of
a particular foreign country may suffer a substantial decline against the U.S.
dollar or some other foreign currency, the Fund may enter into a forward
contract to sell, for a fixed amount of dollars or other currency, the amount of
foreign currency approximating the value of some or all of the Fund's securities
holdings (or securities which the Fund has purchased for its portfolio)
denominated in such foreign currency. Under identical circumstances, the Fund
may enter into a forward contract to sell, for a fixed amount of U.S. dollars or
other currency, an amount of foreign currency other than the currency in which
the securities to be hedged are denominated approximating the value of some or
all of the portfolio securities to be hedged. This method of hedging, called
"cross-hedging," will be selected by the Adviser when it is determined that the
foreign currency in which the portfolio securities are denominated has
insufficient liquidity or is trading at a discount as compared with some other
foreign currency with which it tends to move in tandem.
 
    If the Fund enters into forward contract transactions and the currency in
which the Fund securities holdings (or anticipated portfolio securities) are
denominated rises in value with respect to the currency which is being purchased
(or sold), then the Fund will have realized fewer gains than had the Fund not
entered into the forward contracts. Moreover, the precise matching of the
forward contract amounts and the value of the securities involved will not
generally be possible, since
 
                                       16
<PAGE>
the future value of such securities in foreign currencies will change as a
consequence of market movements in the value of those securities between the
date the forward contract is entered into and the date it matures. The Fund is
not required to enter into such transactions with regard to its foreign
currency-denominated securities and will not do so unless deemed appropriate by
the Adviser.
 
    FUTURES AND OPTIONS TRANSACTIONS.  The Fund is authorized to engage in
futures and options transactions, although it has no current intention to do so
during the coming year.
 
PORTFOLIO MANAGEMENT
 
    The Fund's portfolio is actively managed by its Adviser with a view to
achieving the Fund's investment objective. James A. Tilton, Managing Director of
the Adviser, is the primary portfolio manager of the equity portion of the
Fund's portfolio, and James M. Goldberg, Managing Director of the Adviser, is
the primary portfolio manager of the fixed-income portion of the Fund's
portfolio. Messrs. Tilton and Goldberg, who have been the primary portfolio
managers of the Fund since its inception, have been portfolio managers with
affiliates of The TCW Group, Inc. since 1980 and 1984, respectively.
 
    In determining which securities to purchase for the Fund or hold in the
Fund's portfolio, the Adviser will rely on information from various sources,
including research, analysis and appraisals of brokers and dealers, including
Dean Witter Reynolds Inc. ("DWR"), and other brokers and dealers that are
affiliates of the Manager, and others regarding economic developments and
interest rate trends, and the Adviser's own analysis of factors it deems
relevant.
 
    Orders for transactions in portfolio securities are placed for the Fund with
a number of brokers anddealers, including DWR and other brokers and dealers that
are affiliates of the Manager or Adviser. The Fund may incur brokerage
commissions on transactions conducted through such affiliates. Under normal
circumstances it is not anticipated that the portfolio trading will result in
the Fund's portfolio turnover rate exceeding 150% in any one year. The Fund will
incur brokerage costs commensurate with its portfolio turnover rate, and thus a
higher level (over 100%) of portfolio transactions will increase the Fund's
overall brokerage expenses. Short term gains and losses may result from such
portfolio transactions.
 
    Except as specifically noted, all investment policies and practices
discussed above are not fundamental policies of the Fund and, as such, may be
changed without shareholder approval.
 
INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------
 
    The investment restrictions listed below are among the restrictions which
have been adopted by the Fund as fundamental policies. Under the Investment
Company Act of 1940, as amended (the "Act"), a fundamental policy may not be
changed without the vote of a majority of the outstanding voting securities of
the Fund, as defined in the Act. For purposes of the following limitations: (i)
all percentage limitations apply immediately after a purchase or initial
investment, and (ii) 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 portfolio.
 
    The Fund may not:
 
        1.  As to 75% of its total assets, invest more than 5% of the value of
    its total assets in the securities of any one issuer (other than obligations
    issued or guaranteed by the United States Government, its agencies or
    instrumentalities).
 
        2.  As to 75% of its total assets, purchase more than 10% of the voting
    securities of any issuer.
 
        3.  Invest 25% or more of the value of its total assets in securities of
    issuers in any one industry. This restriction does not apply to obligations
 
                                       17
<PAGE>
    issued or guaranteed by the United States Government, its agencies or
    instrumentalities.
        4.  Invest more than 5% of the value of its total assets in securities
    of issuers having a record, together with predecessors, of less than three
    years of continuous operation. This restriction does not apply to
    obligations issued or guaranteed by the United States Government, its
    agencies or instrumentalities.
 
PURCHASE OF FUND SHARES
- --------------------------------------------------------------------------------
 
GENERAL
 
    The Fund offers each Class of its shares for sale to the public on a
continuous basis. Pursuant to a Distribution Agreement between the Fund and Dean
Witter Distributors Inc. (the "Distributor"), an affiliate of the Manager,
shares of the Fund are distributed by the Distributor and offered by DWR and
others (which may include TCW Brokerage Services, an affiliate of the Adviser)
which have entered into selected dealer agreements with the Distributor
("Selected Broker-Dealers"). The principal executive office of the Distributor
is located at Two World Trade Center, New York, New York 10048.
 
    The Fund offers four classes of shares (each, a "Class"). Class A shares are
sold to investors with an initial sales charge that declines to zero for larger
purchases; however, Class A shares sold without an initial sales charge are
subject to a contingent deferred sales charge ("CDSC") of 1.0% if redeemed
within one year of purchase, except for certain specific circumstances. Class B
shares are sold without an initial sales charge but are subject to a CDSC
(scaled down from 5.0% to 1.0%) payable upon most redemptions within six years
after purchase. (Class B shares purchased by certain qualified
employer-sponsored benefit plans are subject to a CDSC scaled down from 2.0% to
1.0% if redeemed within three years after purchase.) Class C shares are sold
without an initial sales charge but are subject to a CDSC of 1.0% on most
redemptions made within one year after purchase. Class D shares are sold without
an initial sales charge or CDSC and are available only to investors meeting an
initial investment minimum of $5 million, and to certain other limited
categories of investors. At the discretion of the Board of Trustees of the Fund,
Class A shares may be sold to categories of investors in addition to those set
forth in this prospectus at net asset value without a front-end sales charge,
and Class D shares may be sold to certain other categories of investors, in each
case as may be described in the then current prospectus of the Fund. See
"Alternative Purchase Arrangements -- Selecting a Particular Class" for a
discussion of factors to consider in selecting which Class of shares to
purchase.
 
   
    The minimum initial purchase is $1,000 for each Class of shares, although
Class D shares are only available to persons investing $5 million or more and to
certain other limited categories of investors. For the purpose of meeting the
minimum $5 million initial investment for Class D shares, and subject to the
$1,000 minimum initial investment for each Class of the Fund, an investor's
existing holdings of Class A shares and concurrent investments in Class D shares
of the Fund and other TCW/DW Funds which are multiple class funds ("TCW/DW
Multi-Class Funds") will be aggregated. Subsequent purchases of $100 or more may
be made by sending a check, payable to TCW/DW Balanced Fund, directly to Dean
Witter Trust FSB (the "Transfer Agent" or "DWT") at P.O. Box 1040, Jersey City,
NJ 07303 or by contacting an account executive of DWR or other Selected
Broker-Dealer. When purchasing shares of the Fund, investors must specify
whether the purchase is for Class A, Class B, Class C or Class D shares. If no
Class is specified, the Transfer Agent will not process the transaction until
the proper Class is identified. The minimum initial purchase in the case of
investments through EasyInvest-SM-, an automatic purchase plan (see "Shareholder
Services"), is $100, provided that the schedule of automatic investments will
result in investments totalling at least $1,000 within the first twelve months.
The minimum initial investment in the case of an "Education IRA" is $500, if the
Distributor has reason to believe that additional investments will increase the
investment in the account to $1,000 within three years. In the case of
investments
    
 
                                       18
<PAGE>
   
pursuant to (i) Systematic Payroll Deduction Plans (including Individual
Retirement Plans), (ii) the InterCapital mutual fund asset allocation program
and (iii) fee based programs approved by the Distributor, pursuant to which
participants pay an asset based fee for services in the nature of investment
advisory or administrative services, the Fund, in its discretion, may accept
investments without regard to any minimum amounts which would otherwise be
required if the Fund has reason to believe that additional investments will
increase the investment in all accounts under such Plans to at least $1,000.
Certificates for shares purchased will not be issued unless a request is made by
the shareholder in writing to the Transfer Agent.
    
 
    Shares of the Fund are sold through the Distributor on a normal three
business day settlement basis; that is, payment is due on the third business day
(settlement date) after the order is placed with the Distributor. Since DWR and
other Selected Broker-Dealers forward investors' funds on settlement date, they
will benefit from the temporary use of the funds if payment is made prior
thereto. As noted above, orders placed directly with the Transfer Agent must be
accompanied by payment. Investors will be entitled to receive income dividends
and capital gains distributions if their order is received by the close of
business on the day prior to the record date for such dividends and
distributions.
 
    Sales personnel of a Selected Broker-Dealer are compensated for selling
shares of the Fund by the Distributor or any of its affiliates and/or the
Selected Broker-Dealer. In addition, some sales personnel of the Selected
Broker-Dealer will receive various types of non-cash compensation as special
sales incentives, including trips, educational and/or business seminars and
merchandise. The Fund and the Distributor reserve the right to reject any
purchase order.
 
ALTERNATIVE PURCHASE ARRANGEMENTS
 
    The Fund offers several Classes of shares to investors designed to provide
them with the flexibility of selecting an investment best suited to their needs.
The general public is offered three Classes of shares: Class A shares, Class B
shares and Class C shares, which differ principally in terms of sales charges
and rate of expenses to which they are subject. A fourth Class of shares, Class
D shares, is offered only to limited categories of investors (see "No Load
Alternative -- Class D Shares" below).
 
    Each Class A, Class B, Class C or Class D share of the Fund represents an
identical interest in the investment portfolio of the Fund except that Class A,
Class B and Class C shares bear the expenses of the ongoing shareholder service
fees, Class B and Class C shares bear the expenses of the ongoing distribution
fees and Class A, Class B and Class C shares which are redeemed subject to a
CDSC bear the expense of the additional incremental distribution costs resulting
from the CDSC applicable to shares of those Classes. The ongoing distribution
fees that are imposed on Class A, Class B and Class C shares will be imposed
directly against those Classes and not against all assets of the Fund and,
accordingly, such charges against one Class will not affect the net asset value
of any other Class or have any impact on investors choosing another sales charge
option. See "Plan of Distribution" and "Repurchases and Redemptions."
 
    Set forth below is a summary of the differences between the Classes and the
factors an investor should consider when selecting a particular Class. This
summary is qualified in its entirety by detailed discussion of each Class that
follows this summary.
 
    CLASS A SHARES.  Class A shares are sold at net asset value plus an initial
sales charge of up to 5.25%. The initial sales charge is reduced for certain
purchases. Investments of $1 million or more (and investments by certain other
limited categories of investors) are not subject to any sales charges at the
time of purchase but are subject to a CDSC of 1.0% on redemptions made within
one year after purchase, except for certain specific circumstances. Class A
shares are also subject to a 12b-1 fee of up to 0.25% of the average daily net
assets of the Class. See "Initial Sales Charge Alternative -- Class A Shares."
 
    CLASS B SHARES.  Class B shares are offered at net asset value with no
initial sales charge but are subject to a CDSC (scaled down from 5.0% to 1.0%)
if redeemed within six years of purchase. (Class B shares purchased by certain
qualified employer-sponsored benefit plans are subject to a CDSC scaled down
from 2.0% to 1.0% if
 
                                       19
<PAGE>
redeemed within three years after purchase.) This CDSC may be waived for certain
redemptions. Class B shares are also subject to an annual 12b-1 fee of 1.0% of
the average daily net assets of Class B. The Class B shares' distribution fee
will cause that Class to have higher expenses and pay lower dividends than Class
A or Class D shares.
 
    After approximately ten (10) years, Class B shares will convert
automatically to Class A shares of the Fund, based on the relative net asset
values of the shares of the two Classes on the conversion date. In addition, a
certain portion of Class B shares that have been acquired through the
reinvestment of dividends and distributions will be converted at that time. See
"Contingent Deferred Sales Charge Alternative -- Class B Shares."
 
    CLASS C SHARES.  Class C shares are sold at net asset value with no initial
sales charge but are subject to a CDSC of 1.0% on redemptions made within one
year after purchase. This CDSC may be waived for certain redemptions. They are
subject to an annual 12b-1 fee of up to 1.0% of the average daily net assets of
the Class C shares. The Class C shares' distribution fee may cause that Class to
have higher expenses and pay lower dividends than Class A or Class D shares. See
"Level Load Alternative -- Class C Shares."
 
    CLASS D SHARES.  Class D shares are available only to limited categories of
investors (see "No Load Alternative -- Class D Shares" below). Class D shares
are sold at net asset value with no initial sales charge or CDSC. They are not
subject to any 12b-1 fees. See "No Load Alternative -- Class D Shares."
 
    SELECTING A PARTICULAR CLASS.  In deciding which Class of Fund shares to
purchase, investors should
consider the following factors, as well as any other relevant facts and
circumstances:
 
    The decision as to which Class of shares is more beneficial to an investor
depends on the amount and intended length of his or her investment. Investors
who prefer an initial sales charge alternative may elect to purchase Class A
shares. Investors qualifying for significantly reduced or, in the case of
purchases of $1 million or more, no initial sales charges may find Class A
shares particularly attractive because similar sales charge reductions are not
available with respect to Class B or Class C shares. Moreover, Class A shares
are subject to lower ongoing expenses than are Class B or Class C shares over
the term of the investment. As an alternative, Class B and Class C shares are
sold without any initial sales charge so the entire purchase price is
immediately invested in the Fund. Any investment return on these additional
investment amounts may partially or wholly offset the higher annual expenses of
these Classes. Because the Fund's future return cannot be predicted, however,
there can be no assurance that this would be the case.
 
    Finally, investors should consider the effect of the CDSC period and any
conversion rights of the Classes in the context of their own investment time
frame. For example, although Class C shares are subject to a significantly lower
CDSC upon redemptions, they do not, unlike Class B shares, convert into Class A
shares after approximately ten years, and, therefore, are subject to an ongoing
12b-1 fee of 1.0% (rather than the 0.25% fee applicable to Class A shares) for
an indefinite period of time. Thus, Class B shares may be more attractive than
Class C shares to investors with longer term investment outlooks. Other
investors, however, may elect to purchase Class C shares if, for example, they
determine that they do not wish to be subject to a front-end sales charge and
they are uncertain as to the length of time they intend to hold their shares.
 
    For the purpose of meeting the $5 million minimum investment amount for
Class D shares, holdings of Class A shares in all TCW/DW Multi-Class Funds, and
holdings of shares of "Exchange Funds" (see "Shareholder Services -- Exchange
Privilege") for which Class A shares have been exchanged, will be included
together with the current investment amount.
 
    Sales personnel may receive different compensation for selling each Class of
shares. Investors should understand that the purpose of a CDSC is the same as
that of the initial sales charge in that the sales charges applicable to each
Class provide for the financing of the distribution of shares of that Class.

INITIAL SALES CHARGE ALTERNATIVE -- CLASS A SHARES
 
    Class A shares are sold at net asset value plus an initial sales charge. In
some cases, reduced sales charges may be available, as described below.
Investments of $1 million or more (and investments by certain other limited
categories of investors) are not subject to any sales charges at the time of
purchase but are subject to a CDSC of 1.0% on redemptions made within one year
after purchase (calculated from the last day of the month in which the shares
were purchased), except for certain specific circumstances. The CDSC will be
assessed on an amount equal to the lesser of the current market value or the
cost of the shares being redeemed. The CDSC will not be imposed (i) in the
circumstances set forth below in the section "Contingent Deferred Sales Charge
Alternative -- Class B Shares -- CDSC Waivers," except that the references to
six years in the first paragraph of that section shall mean one year in the case
of Class A shares, and (ii) in the circumstances identified in the section
"Additional Net Asset Value Purchase Options" below. Class A shares are also
subject to an annual 12b-1 fee of up to 0.25% of the average daily net assets of
the Class.
 
    The offering price of Class A shares will be the net asset value per share
next determined following receipt of an order (see "Determination of Net Asset
Value" below), plus a sales charge (expressed as a percentage of the offering
price) on a single transaction as shown in the following table:

    Upon notice to all Selected Broker-Dealers, the Distributor may reallow up
to the full applicable sales charge as shown in the above schedule during
periods specified in such notice. During periods when 90% or more of the sales
charge is reallowed, such Selected Broker-Dealers may be deemed to be
underwriters as that term is defined in the Securities Act of 1933.
 
    The above schedule of sales charges is applicable to purchases in a single
transaction by, among others: (a) an individual; (b) an individual, his or her
spouse and their children under the age of 21 purchasing shares for his, her or
their own accounts; (c) a trustee or other fiduciary purchasing shares for a
single trust estate or a single fiduciary account; (d) a pension, profit-sharing
or other employee benefit plan qualified or non-qualified under Section 401 of
the Internal Revenue Code; (e) tax-exempt organizations enumerated in Section
501(c)(3) or (13) of the Internal Revenue Code;
 
                                       21
<PAGE>
(f) employee benefit plans qualified under Section 401 of the Internal Revenue
Code of a single employer or of employers who are "affiliated persons" of each
other within the meaning of Section 2(a)(3)(c) of the Act; and for investments
in Individual Retirement Accounts of employees of a single employer through
Systematic Payroll Deduction plans; or (g) any other organized group of persons,
whether incorporated or not, provided the organization has been in existence for
at least six months and has some purpose other than the purchase of redeemable
securities of a registered investment company at a discount.
 
    COMBINED PURCHASE PRIVILEGE.  Investors may have the benefit of reduced
sales charges in accordance with the above schedule by combining purchases of
Class A shares of the Fund in single transactions with the purchase of Class A
shares of other TCW/DW Multi-Class Funds. The sales charge payable on the
purchase of the Class A shares of the Fund and the Class A shares of the other
TCW/DW Multi-Class Funds will be at their respective rates applicable to the
total amount of the combined concurrent purchases of such shares.
 
    RIGHT OF ACCUMULATION.  The above persons and entities may benefit from a
reduction of the sales charges in accordance with the above schedule if the
cumulative net asset value of Class A shares purchased in a single transaction,
together with shares of the Fund and other TCW/DW Multi-Class Funds previously
purchased at a price including a front-end sales charge (including shares of the
Fund, other TCW/DW Multi-Class Funds or "Exchange Funds" (see "Shareholder
Services -- Exchange Privilege") acquired in exchange for those shares, and
including in each case shares acquired through reinvestment of dividends and
distributions), which are held at the time of such transaction, amounts to
$25,000 or more. If such investor has a cumulative net asset value of Class A
and Class D shares equal to at least $5 million, such investor is eligible to
purchase Class D shares subject to the $1,000 minimum initial investment
requirement of that Class of the Fund. See "No Load Alternative -- Class D
Shares" below.
 
    The Distributor must be notified by DWR or a Selected Broker-Dealer or the
shareholder at the time a purchase order is placed that the purchase qualifies
for the reduced charge under the Right of Accumulation. Similar notification
must be made in writing by the dealer or shareholder when such an order is
placed by mail. The reduced sales charge will not be granted if: (a) such
notification is not furnished at the time of the order; or (b) a review of the
records of the Selected Broker-Dealer or the Transfer Agent fails to confirm the
investor's represented holdings.
 
    LETTER OF INTENT.  The foregoing schedule of reduced sales charges will also
be available to investors who enter into a written Letter of Intent providing
for the purchase, within a thirteen-month period, of Class A shares of the Fund
from DWR or other Selected Broker-Dealers. The cost of Class A shares of the
Fund or Class A shares of other TCW/DW Multi-Class Funds which were previously
purchased at a price including a front-end sales charge during the 90-day period
prior to the date of receipt by the Distributor of the Letter of Intent, or of
Class A shares of the Fund or other TCW/DW Multi-Class Funds or shares of
"Exchange Funds" (see "Shareholder Services -- Exchange Privilege") acquired in
exchange for Class A shares of such funds purchased during such period at a
price including a front-end sales charge, which are still owned by the
shareholder, may also be included in determining the applicable reduction.
 
    ADDITIONAL NET ASSET VALUE PURCHASE OPTIONS.  In addition to investments of
$1 million or more, Class A shares also may be purchased at net asset value by
the following:
 
   
    (1)  trusts for which DWT (an affiliate of the Investment Manager) provides
discretionary trustee services;
    
 
   
    (2)  persons participating in a fee-based program approved by the
Distributor, pursuant to which such persons pay an asset based fee for services
in the nature of investment advisory or administrative services (such
investments are subject to all of the terms and conditions of such programs,
which may include termination fees, mandatory redemption upon termination and

the interim in cash or a money market fund; and
 
    (6)  other categories of investors, at the discretion of the Board, as
disclosed in the then current prospectus of the Fund.

CONTINGENT DEFERRED SALES CHARGE ALTERNATIVE -- CLASS B SHARES
 
    Class B shares are sold at net asset value next determined without an
initial sales charge so that the full amount of an investor's purchase payment
may be immediately invested in the Fund. A CDSC, however, will be imposed on
most Class B shares redeemed within six years after purchase. The CDSC will be
imposed on any redemption of shares if after such redemption the aggregate
current value of a Class B account with the Fund falls below the aggregate
amount of the investor's purchase payments for Class B shares made during the
six years (or, in the case of shares held by certain employer-sponsored benefit
plans, three years) preceding the redemption. In addition, Class B shares are
subject to an annual 12b-1 fee of 1.0% of the average daily net assets of Class
B.
 
    Except as noted below, Class B shares of the Fund which are held for six
years or more after purchase (calculated from the last day of the month in which
the shares were purchased) will not be subject to any CDSC upon redemption.
Shares redeemed earlier than six years after purchase may, however, be subject
to a CDSC which will be a percentage of the dollar amount of shares redeemed and
will be assessed on an amount equal to the lesser of the current market value or
the cost of the shares being redeemed. The size of this percentage will depend
upon how long the shares have been held, as set forth in the following table:

serves as recordkeeper and whose accounts are opened on or after July 28, 1997,

    CDSC WAIVERS.  A CDSC will not be imposed on: (i) any amount which
represents an increase in value of shares purchased within the six years (or, in
the case of shares held by certain employer-sponsored benefit plans, three
years) preceding the redemption; (ii) the current net asset value of shares
purchased more than six years (or, in the case of shares held by certain
employer-sponsored benefit plans, three years) prior to the redemption; and
(iii) the current net asset value of shares purchased through reinvestment of
dividends or distributions. Moreover, in determining whether a CDSC is
applicable it will be assumed that amounts described in (i), (ii) and (iii)
above (in that order) are redeemed first.
 
    In addition, the CDSC, if otherwise applicable, will be waived in the case
of:
 
    (1)  redemptions of shares held at the time a shareholder dies or becomes
disabled, only if the shares are:  (a) registered either in the name of an
individual shareholder (not a trust), or in the names of such shareholder and
his or her spouse as joint tenants with right of survivorship; or  (b) held in a
qualified corporate or self-employed retirement plan, Individual Retirement
Account ("IRA") or Custodial Account under Section 403(b)(7) of the Internal
Revenue Code ("403(b) Custodial Account"), provided in either case that the
redemption is requested within one year of the death or initial determination of
disability;
 
    (2)  redemptions in connection with the following retirement plan
distributions:  (a) lump-sum or other distributions from a qualified corporate
or self-employed retirement plan following retirement (or, in the case of a "key
employee" of a "top heavy" plan, following attainment of age 59 1/2);  (b)
distributions from an IRA or 403(b) Custodial Account following attainment of
age 59 1/2; or  (c) a tax-free return of an excess contribution to an IRA; and
 
   
    (3)  all redemptions of shares held for the benefit of a participant in a
401(k) plan or other employer-sponsored plan qualified under Section 401(a) of
the Internal Revenue Code which offers investment companies managed by the
Manager or its parent, Dean Witter InterCapital Inc., as self-directed
investment alternatives and for which DWT serves as Trustee or the 401(k)
Support Services Group of DWR serves as recordkeeper ("Eligible Plan"), provided
that either: (a) the plan continues to be an Eligible Plan after the redemption;
or  (b) the redemption is in connection with the complete termination of the
plan involving the distribution of all plan assets to participants.
    
 
    With reference to (1) above, for the purpose of determining disability, the
Distributor utilizes the definition of disability contained in Section 72(m)(7)
of the Internal Revenue Code, which relates to the inability to engage in
gainful employment. With reference to (2) above, the term "distribution" does
not encompass a direct transfer of IRA, 403(b) Custodial Account or retirement
plan assets to a successor custodian or trustee. All waivers will be granted
only following receipt by the Distributor of confirmation of the shareholder's
entitlement.
 
    CONVERSION TO CLASS A SHARES.  Shares of the Fund held prior to July 28,
1997 which were acquired in exchange for shares of TCW/DW Funds sold with a
CDSC, including shares acquired through reinvestment of dividends and
distributions thereon, have been designated Class B shares. Shares held before
May 1, 1997 will convert to Class A shares in May, 2007. In all other instances
Class B shares will convert automatically to Class A shares, based on the
relative net asset values of the shares of the two Classes on the conversion
date, which will be approximately ten (10) years after the date of the original
purchase. The ten year period is calculated from the last day of the month in
which the shares were purchased or, in the case of Class B shares acquired
through an exchange or a series of exchanges, from the last day of the month in
which the original Class B shares were purchased, provided that shares
originally purchased before May 1, 1997 will convert to Class A shares in May,
2007. The con-
 
                                       24
<PAGE>
   
version of shares purchased on or after May 1, 1997 will take place in the month
following the tenth anniversary of the purchase. There will also be converted at
that time such proportion of Class B shares acquired through automatic
reinvestment of dividends and distributions owned by the shareholder as the
total number of his or her Class B shares converting at the time bears to the
total number of outstanding Class B shares purchased and owned by the
shareholder. In the case of Class B shares held by a 401(k) plan or other
employer-sponsored plan qualified under Section 401(a) of the Internal Revenue
Code and for which DWT serves as Trustee or the 401(k) Support Services Group of
DWR serves as recordkeeper, the plan is treated as a single investor and all
Class B shares will convert to Class A shares on the conversion date of the
first shares of a TCW/DW Multi-Class Fund purchased by that plan. In the case of
Class B shares previously exchanged for shares of an "Exchange Fund" (see
"Shareholder Services -- Exchange Privilege"), the period of time the shares
were held in the Exchange Fund (calculated from the last day of the month in
which the Exchange Fund shares were acquired) is excluded from the holding
period for conversion. If those shares are subsequently re-exchanged for Class B
shares of a TCW/DW Multi-Class Fund, the holding period resumes on the last day
of the month in which Class B shares are reacquired.
    
 
    If a shareholder has received share certificates for Class B shares, such
certificates must be delivered to the Transfer Agent at least one week prior to
the date for conversion. Class B shares evidenced by share certificates that are
not received by the Transfer Agent at least one week prior to any conversion
date will be converted into Class A shares on the next scheduled conversion date
after such certificates are received.
 
   
    Effectiveness of the conversion feature is subject to the continuing
availability of a ruling of the Internal Revenue Service or an opinion of
counsel that (i) the conversion of shares does not constitute a taxable event
under the Internal Revenue Code, (ii) Class A shares received on conversion will
have a basis equal to the shareholder's basis in the converted Class B shares
immediately prior to the conversion, and (iii) Class A shares received on
conversion will have a holding period that includes the holding period of the
converted Class B shares. The conversion feature may be suspended if the ruling
or opinion is no longer available. In such event, Class B shares would continue
to be subject to Class B 12b-1 fees.
    
 
LEVEL LOAD ALTERNATIVE -- CLASS C SHARES
 
    Class C shares are sold at net asset value next determined without an
initial sales charge but are subject to a CDSC of 1.0% on most redemptions made
within one year after purchase (calculated from the last day of the month in
which the shares were purchased). The CDSC will be assessed on an amount equal
to the lesser of the current market value or the cost of the shares being
redeemed. The CDSC will not be imposed in the circumstances set forth above in
the section "Contingent Deferred Sales Charge Alternative -- Class B Shares --
CDSC Waivers," except that the references to six years in the first paragraph of
that section shall mean one year in the case of Class C shares. Class C shares
are subject to an annual 12b-1 fee of up to 1.0% of the average daily net assets
of the Class. Unlike Class B shares, Class C shares have no conversion feature
and, accordingly, an investor that purchases Class C shares will be subject to
12b-1 fees applicable to Class C shares for an indefinite period subject to
annual approval by the Fund's Board of Trustees and regulatory limitations. All
shares of the Fund held prior to July 28, 1997 (other than shares which were
acquired in exchange for shares of TCW/ DW Funds sold with a CDSC and shares
acquired through reinvestment of dividends and distributions thereon) have been
designated Class C shares. Shares held before July 28, 1997 that have been
designated Class C shares are not subject to the 1.0% CDSC.
 
NO LOAD ALTERNATIVE -- CLASS D SHARES
 
    Class D shares are offered without any sales charge on purchase or
redemption and without any 12b-1 fee. Class D shares are offered only to
investors meeting an initial investment minimum of $5 million and the following
categories of investors: (i) investors participating in the InterCapital mutual
fund asset allocation program pursuant to which such persons pay an asset based
fee; (ii) persons participating in a fee-based program approved by the
Distributor, pursuant to which such persons pay an asset based fee for services
in the nature
 
                                       25
<PAGE>
   
of investment advisory or administrative services (subject to all of the terms
and conditions of such programs referred to in (i) and (ii) above, which may
include termination fees, mandatory redemption upon termination and such other
circumstances as specified in the programs' agreements, and restrictions on
transferability of Fund shares); (iii) certain Unit Investment Trusts sponsored
by DWR; (iv) certain other open-end investment companies whose shares are
distributed by the Distributor; and (v) other categories of investors, at the
discretion of the Board, as disclosed in the then current prospectus of the
Fund. Investors who require a $5 million minimum initial investment to qualify
to purchase Class D shares may satisfy that requirement by investing that amount
in a single transaction in Class D shares of the Fund and other TCW/DW
Multi-Class Funds, subject to the $1,000 minimum initial investment required for
that Class of the Fund. In addition, for the purpose of meeting the $5 million
minimum investment amount, holdings of Class A shares in all TCW/DW Multi-Class
Funds, and holdings of shares of "Exchange Funds" (see "Shareholder Services --
Exchange Privilege") for which Class A shares have been exchanged, will be
included together with the current investment amount. If a shareholder redeems
Class A shares and purchases Class D shares, such redemption may be a taxable
event.
    
 
PLAN OF DISTRIBUTION
 
    The Fund has adopted a Plan of Distribution pursuant to Rule 12b-1 under the
Act with respect to the distribution of Class A, Class B and Class C shares of
the Fund. In the case of Class A and Class C shares, the Plan provides that the
Fund will reimburse the Distributor and others for the expenses of certain
activities and services incurred by them specifically on behalf of those shares.
Reimbursements for these expenses will be made in monthly payments by the Fund
to the Distributor, which will in no event exceed amounts equal to payments at
the annual rates of 0.25% and 1.0% of the average daily net assets of Class A
and Class C, respectively. In the case of Class B shares, the Plan provides that
the Fund will pay the Distributor a fee, which is accrued daily and paid
monthly, at the annual rate of 1.0% of the average daily net assets of Class B.
The fee is treated by the Fund as an expense in the year it is accrued. In the
case of Class A shares, the entire amount of the fee currently represents a
service fee within the meaning of the NASD guidelines. In the case of Class B
and Class C shares, a portion of the fee payable pursuant to the Plan, equal to
0.25% of the average daily net assets of each of these Classes, is currently
characterized as a service fee. A service fee is a payment made for personal
service and/or the maintenance of shareholder accounts.
 
    Additional amounts paid under the Plan in the case of Class B and Class C
shares are paid to the Distributor for services provided and the expenses borne
by the Distributor and others in the distribution of the shares of those
Classes, including the payment of commissions for sales of the shares of those
Classes and incentive compensation to and expenses of DWR's account executives
and others who engage in or support distribution of shares or who service
shareholder accounts, including overhead and telephone expenses; printing and
distribution of prospectuses and reports used in connection with the offering of
the Fund's shares to other than current shareholders; and preparation, printing
and distribution of sales literature and advertising materials. In addition, the
Distributor may utilize fees paid pursuant to the Plan in the case of Class B
shares to compensate DWR and other Selected Broker-Dealers for their opportunity
costs in advancing such amounts, which compensation would be in the form of a
carrying charge on any unreimbursed expenses.
 
   
    For the fiscal year ended September 30, 1997, Class C shares of the Fund
accrued payments under the Plan amounting to $908,897, which amount is equal to
0.99% of the average daily net assets of Class C for the fiscal year. All shares
held prior to July 28, 1997 have been designated Class C shares. For the fiscal
period July 28 through September 30, 1997, Class A and Class B shares of the
Fund accrued payments under the Plan amounting to $13 and $9,461, respectively,
which amounts on an annualized basis are equal to 0.25% and 1.00% of the average
daily net assets of Class A and Class B, respectively, for such period.
    
 
    In the case of Class B shares, at any given time, the expenses in
distributing Class B shares of the Fund may be in excess of the total of (i) the
payments made by the Fund pursuant to the Plan, and (ii) the proceeds of CDSCs
paid by investors upon the redemption of
 
                                       26
<PAGE>
   
Class B shares. For example, if $1 million in expenses in distributing Class B
shares of the Fund had been incurred and $750,000 had been received as described
in (i) and (ii) above, the excess expense would amount to $250,000. The
Distributor has advised the Fund that there were no such excess amounts,
including the carrying charge described above, for Class B at September 30,
1997. Because there is no requirement under the Plan that the Distributor be
reimbursed for all distribution expenses or any requirement that the Plan be
continued from year to year, such excess amount does not constitute a liability
of the Fund. Although there is no legal obligation for the Fund to pay expenses
incurred in excess of payments made to the Distributor under the Plan, and the
proceeds of CDSCs paid by investors upon redemption of shares, if for any reason
the Plan is terminated the Trustees will consider at that time the manner in
which to treat such expenses. Any cumulative expenses incurred, but not yet
recovered through distribution fees or CDSCs, may or may not be recovered
through future distribution fees or CDSCs.
    
 
   
    In the case of Class A and Class C shares, expenses incurred pursuant to the
Plan in any calendar year in excess of 0.25% or 1.0% of the average daily net
assets of Class A or Class C, respectively, will not be reimbursed by the Fund
through payments in any subsequent year, except that expenses representing a
gross sales commission credited to account executives at the time of sale may be
reimbursed in the subsequent calendar year. The Distributor has advised the Fund
that there were no such expenses which may be reimbursed in the subsequent year
in the case of Class A and Class C on such date. No interest or other financing
charges will be incurred on any Class A or Class C distribution expenses
incurred by the Distributor under the Plan or on any unreimbursed expenses due
to the Distributor pursuant to the Plan.
    
 
DETERMINATION OF NET ASSET VALUE
 
    The net asset value per share is determined once daily at 4:00 p.m., New
York time (or, on days when the New York Stock Exchange closes prior to 4:00
p.m., at such earlier time), on each day that the New York Stock Exchange is
open by taking the net assets of the Fund, dividing by the number of shares
outstanding and adjusting to the nearest cent. The assets belonging to the Class
A, Class B, Class C and Class D shares will be invested together in a single
portfolio. The net asset value of each Class, however, will be determined
separately by subtracting each Class's accrued expenses and liabilities. The net
asset value per share will not be determined on Good Friday and on such other
federal and non-federal holidays as are observed by the New York Stock Exchange.
 
    In the calculation of the Fund's net asset value: (1) an equity portfolio
security listed or traded on the New York or American Stock Exchange or other
stock exchange is valued at its latest sale price on that exchange prior to the
time when assets are valued; if there were no sales that day, the security, is
valued at the latest bid price (in cases where securities are traded on more
than one exchange, the securities are valued on the exchange designated as the
primary market pursuant to procedures adopted by the Trustees); and (2) all
other portfolio securities for which over-the-counter market quotations are
readily available are valued at the latest available bid price prior to the time
of valuation. When market quotations are not readily available, including
circumstances under which it is determined by the Adviser that sale or bid
prices are not reflective of a security's market value, portfolio securities are
valued at their fair value as determined in good faith under procedures
established by and under the general supervision of the Fund's Trustees. For
valuation purposes, quotations of foreign portfolio securities are translated
into U.S. dollar equivalents at the prevailing market rates prior to the close
of the New York Stock Exchange as of the morning of valuation. Dividends
receivable are accrued as of the ex-dividend date or as of the time that the
relevant ex-dividend date and amounts become known.
 
    Short-term debt securities with remaining maturities of 60 days or less at
the time of purchase are valued at amortized cost, unless the Trustees determine
such does not reflect the securities' market value, in which case these
securities will be valued at their fair value as determined by the Trustees.
 
    Certain of the Fund's portfolio securities may be valued by an outside
pricing service approved by the Fund's Trustees. The pricing service may utilize
a matrix system incorporating security quality, maturity
 
                                       27
<PAGE>
and coupon as the evaluation model parameters, and/or research and evaluations
by its staff, including review of broker-dealer market price quotations, in
determining what it believes is the fair valuation of the portfolio securities
valued by such pricing service.
 
SHAREHOLDER SERVICES
- --------------------------------------------------------------------------------
 
    AUTOMATIC INVESTMENT OF DIVIDENDS AND DISTRIBUTIONS. All income dividends
and capital gains distributions are automatically paid in full and fractional
shares of the applicable Class of the Fund (or, if specified by the shareholder,
in shares of any other open-end TCW/DW Fund), unless the shareholder requests
that they be paid in cash. Shares so acquired are acquired at net asset value
and are not subject to the imposition of a front-end sales charge or a CDSC (see
"Repurchases and Redemptions").
 
    INVESTMENT OF DIVIDENDS OR DISTRIBUTIONS RECEIVED IN CASH.  Any shareholder
who receives a cash payment representing a dividend or capital gains
distribution may invest such dividend or distribution in shares of the
applicable Class at the net asset value per share next determined after receipt
by the Transfer Agent, by returning the check or the proceeds to the Transfer
Agent within 30 days after the payment date. Shares so acquired are acquired at
net asset value and are not subject to the imposition of a front-end sales
charge or a CDSC (see "Repurchases and Redemptions").
 
    EASYINVEST-SM-.  Shareholders may subscribe to EasyInvest, an automatic
purchase plan which provides for any amount from $100 to $5,000 to be
transferred automatically from a checking or savings account or following
redemption of shares of a Dean Witter money market fund, on a semi-monthly,
monthly or quarterly basis, to the Transfer Agent for investment in shares of
the Fund. (See "Purchase of Fund Shares" and "Repurchases and Redemptions --
Involuntary Redemption").
 
    SYSTEMATIC WITHDRAWAL PLAN.  A systematic withdrawal plan (the "Withdrawal
Plan") is available for shareholders who own or purchase shares of the Fund
having a minimum value of $10,000 based upon the then current net asset value.
The Withdrawal Plan provides for monthly or quarterly (March, June, September
and December) checks in any dollar amount, not less than $25, or in any whole
percentage of the account balance, on an annualized basis. Any applicable CDSC
will be imposed on shares redeemed under the Withdrawal Plan (see "Purchase of
Fund Shares"). Therefore, any shareholder participating in the Withdrawal Plan
will have sufficient shares redeemed from his or her account so that the
proceeds (net of any applicable CDSC) to the shareholder will be the designated
monthly or quarterly amount. Withdrawal plan payments should not be considered
as dividends, yields or income. If periodic withdrawal plan payments
continuously exceed net investment income and net capital gains, the
shareholder's original investment will be correspondingly reduced and ultimately
exhausted. Each withdrawal constitutes a redemption of shares and any gain or
loss realized must be recognized for federal income tax purposes.
 
    Shareholders should contact their DWR or other Selected Broker-Dealer
account executive or the Transfer Agent for further information about any of the
above services.
 
    TAX SHELTERED RETIREMENT PLANS.  Retirement plans are available for use by
corporations, the self-employed, Individual Retirement Accounts and Custodial
Accounts under Section 403(b)(7) of the Internal Revenue Code. Adoption of such
plans should be on advice of legal counsel or tax adviser.
 
    For further information regarding plan administration, custodial fees and
other details, investors should contact their DWR or other Selected Broker-
Dealer account executive or the Fund.
 
EXCHANGE PRIVILEGE
 
    Shares of each Class may be exchanged for shares of the same Class of any
other TCW/DW Multi-Class Fund without the imposition of any exchange fee. Shares
may also be exchanged for shares of TCW/DW North American Government Income
Trust and for shares of five money market funds for which InterCapital serves as
investment manager: Dean Witter Liquid Asset Fund Inc., Dean Witter U.S.
Government
 
                                       28
<PAGE>
Money Market Trust, Dean Witter Tax-Free Daily Income Trust, Dean Witter
California Tax-Free Daily Income Trust and Dean Witter New York Municipal Money
Market Trust (the foregoing six funds are hereinafter collectively referred to
as "Exchange Funds"). Exchanges may be made after the shares of the Fund
acquired by purchase (not by exchange or dividend reinvestment) have been held
for thirty days. There is no waiting period for exchanges of shares acquired by
exchange or dividend reinvestment.
 
    An exchange to another TCW/DW Multi-Class Fund or any Exchange Fund that is
not a money market fund is on the basis of the next calculated net asset value
per share of each fund after the exchange order is received. When exchanging
into a money market fund from the Fund, shares of the Fund are redeemed out of
the Fund at their next calculated net asset value and the proceeds of the
redemption are used to purchase shares of the money market fund at their net
asset value determined the following business day. Subsequent exchanges between
any of the money market funds and any of the TCW/DW Multi-Class Funds or any
Exchange Fund that is not a money market fund can be effected on the same basis.
 
   
    No CDSC is imposed at the time of any exchange of shares, although any
applicable CDSC will be imposed upon ultimate redemption. During the period of
time the shareholder remains in an Exchange Fund (calculated from the last day
of the month in which the Exchange Fund shares were acquired), the holding
period (for the purpose of determining the rate of the CDSC) is frozen. If those
shares are subsequently re-exchanged for shares of a TCW/DW Multi-Class Fund,
the holding period previously frozen when the first exchange was made resumes on
the last day of the month in which shares of a TCW/DW Multi-Class Fund are
reacquired. Thus, the CDSC is based upon the time (calculated as described
above) the shareholder was invested in shares of a TCW/DW Multi-Class Fund (see
"Purchase of Fund Shares"). In the case of shares exchanged into an Exchange
Fund, upon a redemption of shares which results in a CDSC being imposed, a
credit (not to exceed the amount of the CDSC) will be given in an amount equal
to the Exchange Fund 12b-1 distribution fees which are attributable to those
shares. (Exchange Fund 12b-1 distribution fees are described in the prospectuses
for those funds.)
    
 
    ADDITIONAL INFORMATION REGARDING EXCHANGES. Purchases and exchanges should
be made for investment purposes only. A pattern of frequent exchanges may be
deemed by the Manager to be abusive and contrary to the best interests of the
Fund's other shareholders and, at the Manager's discretion, may be limited by
the Fund's refusal to accept additional purchases and/or exchanges from the
investor. Although the Fund does not have any specific definition of what
constitutes a pattern of frequent exchanges, and will consider all relevant
factors in determining whether a particular situation is abusive and contrary to
the best interests of the Fund and its other shareholders, investors should be
aware that the Fund, each of the other TCW/DW Funds and each of the money market
funds may in their discretion limit or otherwise restrict the number of times
this Exchange Privilege may be exercised by any investor. Any such restriction
will be made by the Fund on a prospective basis only, upon notice to the
shareholder not later than ten days following such shareholder's most recent
exchange. Also, the Exchange Privilege may be terminated or revised at any time
by the Fund and/or any of such TCW/DW Funds or money market funds for which
shares of the Fund have been exchanged, upon such notice as may be required by
applicable regulatory agencies. Shareholders maintaining margin accounts with
DWR or another Selected Broker-Dealer are referred to their account executive
regarding restrictions on exchange of shares pledged in the margin account.
 
    The current prospectus for each fund describes its investment objective(s)
and policies, and shareholders should obtain a copy and examine it carefully
before investing. Exchanges are subject to the minimum investment requirement of
each Class of shares and any other conditions imposed by each fund. In the case
of a shareholder holding a share certificate or certificates, no exchanges may
be made until all applicable share certificates have been received by the
Transfer Agent and deposited in the shareholder's account. An exchange will be
treated for federal income tax pur-
 
                                       29

poses the same as a repurchase or redemption of shares, on which the shareholder
may realize a capital gain or loss. However, the ability to deduct capital
losses on an exchange may be limited in situations where there is an exchange of
shares within ninety days after the shares are purchased. The Exchange Privilege
is only available in states where an exchange may legally be made.
 
   
    If DWR or another Selected Broker-Dealer is the current dealer of record and
its account numbers are part of the account information, shareholders may
initiate an exchange of shares of the Fund for shares of any of the funds for
which the Exchange Privilege is available pursuant to this Exchange Privilege by
contacting their DWR or other Selected Broker-Dealer account executive (no
Exchange Privilege Authorization Form is required). Other shareholders (and
those shareholders who are clients of DWR or another Selected Broker-Dealer but
who wish to make exchanges directly by writing or telephoning the Transfer
Agent) must complete and forward to the Transfer Agent an Exchange Privilege
Authorization Form, copies of which may be obtained from the Transfer Agent, to
initiate an exchange. If the Authorization Form is used, exchanges may be made
in writing or by contacting the Transfer Agent at (800) 869-NEWS (toll-free).
The Fund will employ reasonable procedures to confirm that exchange instructions
communicated over the telephone are genuine. The procedures include requiring
various forms of personal identification such as name, mailing address, social
security or other tax identification number and DWR or other Selected Broker-
Dealer account number (if any). Telephone instructions will also be recorded. If
such procedures are not employed, the Fund may be liable for any losses due to
unauthorized or fraudulent instructions.
    
 
    Telephone exchange instructions will be accepted if received by the Transfer
Agent between 9:00 a.m. and 4:00 p.m., New York time, on any day the New York
Stock Exchange is open. Any shareholder wishing to make an exchange who has
previously filed an Exchange Privilege Authorization Form and who is unable to
reach the Fund by telephone should contact his or her DWR or other Selected
Broker-Dealer account executive, if appropriate, or make a written exchange
request. Shareholders are advised that during periods of drastic economic or
market changes, it is possible that the telephone exchange procedures may be
difficult to implement, although this has not been the case in the past with
other funds managed by the Manager.
 
    For further information regarding the Exchange Privilege, shareholders
should contact their DWR or other Selected Broker-Dealer account executive or
the Transfer Agent.
 
REPURCHASES AND REDEMPTIONS
- --------------------------------------------------------------------------------
 
   
    REPURCHASES.  DWR and other Selected Broker-Dealers are authorized to
repurchase shares represented by a share certificate which is delivered to any
of their offices. Shares held in a shareholder's account without a share
certificate may also be repurchased by DWR and other Selected Broker-Dealers
upon the telephonic request of the shareholder. The repurchase price is the net
asset value next determined (see "Purchase of Fund Shares") after such
repurchase order is received by DWR or other Selected Broker-Dealer reduced by
any applicable CDSC.
    
 
    The CDSC, if any, will be the only fee imposed by the Fund or the
Distributor. The offer by DWR and other Selected Broker-Dealers to repurchase
shares may be suspended without notice by them at any time. In that event,
shareholders may redeem their shares through the Fund's Transfer Agent as set
forth below under "Redemptions."
 
    REDEMPTIONS.  Shares of each Class of the Fund can be redeemed for cash at
any time at net asset value per share next determined less the amount of any
applicable CDSC in the case of Class A, Class B or Class C shares (see "Purchase
of Fund Shares"). If shares are held in a shareholder's account without a share
certificate, a written request for redemption to the Fund's Transfer Agent at
P.O. Box 983, Jersey City, NJ 07303 is required. If certificates are held by the
shareholder, the shares may be redeemed by surrendering the certif-
 
                                       30
<PAGE>
icates with a written request for redemption, along with any additional
information required by the Transfer Agent.
 
    PAYMENT FOR SHARES REPURCHASED OR REDEEMED.  Payment for shares presented
for repurchase or redemption will be made by check within seven days after
receipt by the Transfer Agent of the certificate and/or written request in good
order. Such payment may be postponed or the right of redemption suspended under
unusual circumstances. If the shares to be redeemed have recently been purchased
by check, payment of the redemption proceeds may be delayed for the minimum time
needed to verify that the check used for investment has been honored (not more
than fifteen days from the time of receipt of the check by the Transfer Agent).
Shareholders maintaining margin accounts with DWR or another Selected
Broker-Dealer are referred to their account executive regarding restrictions on
redemption of shares of the Fund pledged in the margin account.
 
    REINSTATEMENT PRIVILEGE.  A shareholder who has had his or her shares
repurchased or redeemed and has not previously exercised this reinstatement
privilege may, within 35 days after the date of the repurchase or redemption,
reinstate any portion or all of the proceeds of such repurchase or redemption in
shares of the Fund in the same Class from which such shares were redeemed or
repurchased, at net asset value next determined after a reinstatement request,
together with the proceeds, is received by the Transfer Agent and receive a pro
rata credit for any CDSC paid in connection with such redemption or repurchase.
 
    INVOLUNTARY REDEMPTION.  The Fund reserves the right, on 60 days' notice, to
redeem, at their net asset value, the shares of any shareholder (other than
shares held in an Individual Retirement Account or Custodial Account under
Section 403(b)(7) of the Internal Revenue Code) whose shares due to redemptions
by the shareholder have a value of less than $100 or such lesser amount as may
be fixed by the Trustees or, in the case of an account opened through
EasyInvest-SM-, if after twelve months the shareholder has invested less than
$1,000 in the account. However, before the Fund redeems such shares and sends
the proceeds to the shareholder, it will notify the shareholder that the value
of the shares is less than the applicable amount and allow him or her 60 days to
make an additional investment in an amount which will increase the value of his
or her account to at least the applicable amount or more before the redemption
is processed. No CDSC will be imposed on any involuntary redemption.
 
DIVIDENDS, DISTRIBUTIONS AND TAXES
- --------------------------------------------------------------------------------
 
    DIVIDENDS AND DISTRIBUTIONS.  The Fund declares dividends separately for
each Class of shares and intends to pay quarterly income dividends and to
distribute net short-term and net long-term capital gains, if any, at least once
each year. The Fund may, however, determine either to distribute or to retain
all or part of any net long-term capital gains in any year for reinvestment.
 
    All dividends and any capital gains distributions will be paid in additional
shares of the same Class and automatically credited to the shareholder's account
without issuance of a share certificate unless the shareholder requests in
writing that all dividends and/or distributions be paid in cash. Shares acquired
by dividend and distribution reinvestments will not be subject to any front-end
sales charge or CDSC. Class B shares acquired through dividend and distribution
reinvestments will become eligible for conversion to Class A shares on a pro
rata basis. Distributions paid on Class A and Class D shares will be higher than
for Class B and Class C shares because distribution fees paid by Class B and
Class C shares are higher. (See "Shareholder Services -- Automatic Investment of
Dividends and Distributions.")
 
    TAXES.  Because the Fund intends to distribute all of its net investment
income and capital gains to shareholders and otherwise continue to qualify as a
regulated investment company under Subchapter M of the Internal Revenue Code, it
is not expected that the Fund will be required to pay any federal income tax.
Shareholders who are required to pay taxes on their income will normally have to
pay federal income taxes, and any
 
                                       31
<PAGE>
   
state income taxes, on the dividends and distributions they receive from the
Fund. Such dividends and distributions to the extent that they are derived from
net investment income or short-term capital gains, are taxable to the
shareholder as ordinary income regardless of whether the shareholder receives
such payments in additional shares or in cash. Any dividends declared in the
last quarter of any calendar year which are paid in the following year prior to
February 1 will be deemed to have been received by the shareholder in the prior
year. Dividend payments will be eligible for the federal dividends received
deduction available to the Fund's corporate shareholders only to the extent the
aggregate dividends received by the Fund would be eligible for the deduction if
the Fund were the shareholder claiming the dividends received deduction. In this
regard, a 46-day holding period within a 90 day period beginning 45 days before
the ex-dividend date of each qualifying dividend generally must be met by the
Fund and the shareholder.
    
 
    Distributions of net long-term capital gains, if any, are taxable to
shareholders as long-term capital gains regardless of how long a shareholder has
held the Fund's shares and regardless of whether the distribution is received in
additional shares or in cash. Capital gains distributions are not eligible for
the dividends received deduction.
 
    The Fund may at times make payments from sources other than income or net
capital gains. Payments from such sources would, in effect, represent a return
of a portion of each shareholder's investment. All, or a portion, of such
payments would not be taxable to shareholders.
 
   
    After the end of the calendar year, shareholders will be sent full
information on their dividends and capital gains distributions for tax purposes.
To avoid being subject to a 31% federal backup withholding tax on taxable
dividends, capital gains distributions and on the proceeds of redemptions and
repurchases, shareholders' taxpayer identification numbers must be furnished and
certified as to their accuracy.
    
 
    Shareholders should consult their tax advisers as to the applicability of
the foregoing to their current situation.
 
PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
 
    From time to time the Fund may quote its "yield" and/or its "total return"
in advertisements and sales literature. These figures are computed separately
for Class A, Class B, Class C and Class D shares. Both the yield and the total
return of the Fund are based on historical earnings and are not intended to
indicate future performance. The yield of each Class of the Fund is computed by
dividing the Class's net investment income over a 30-day period by an average
value (using the average number of shares entitled to receive dividends and the
net asset value per share at the end of the period), all in accordance with
applicable regulatory requirements. Such amount is compounded for six months and
then annualized for a twelve-month period to derive the yield of the Fund for
each Class.
 
    The "average annual total return" of the Fund refers to a figure reflecting
the average annualized percentage increase (or decrease) in the value of an
initial investment in a Class of the Fund of $1,000 over a period of one, five
and ten years or over the life of the Fund, if less than any of the foregoing.
Average annual total return reflects all income earned by the Fund, any
appreciation or depreciation of the Fund's assets, all expenses incurred by the
applicable Class and all sales charges which would be incurred by shareholders,
for the stated periods. It also assumes reinvestment of all dividends and
distributions paid by the Fund.
 
   
    In addition to the foregoing, the Fund may advertise its total return for
each Class over different periods of time by means of aggregate, average, and
year-by-year or other types of total return figures. Such calculations may or
may not reflect the deduction of any sales charge which, if reflected, would
reduce the performance quoted. The Fund may also advertise the growth of
hypothetical investments of $10,000, $50,000 and $100,000 in each Class of
shares of the Fund. The Fund from time to time may also advertise its
performance relative to certain performance rankings and indexes compiled by
independent organizations (such as mutual fund performance rankings of Lipper
Analytical Services, Inc.).
    
 
                                       32

ADDITIONAL INFORMATION
- --------------------------------------------------------------------------------
 
    VOTING RIGHTS.  All shares of beneficial interest of the Fund are of $0.01
par value and are equal as to earnings, assets and voting privileges except that
each Class will have exclusive voting privileges with respect to matters
relating to distribution expenses borne solely by such Class or any other matter
in which the interests of one Class differ from the interests of any other
Class. In addition, Class B shareholders will have the right to vote on any
proposed material increase in Class A's expenses, if such proposal is submitted
separately to Class A shareholders. Also, as discussed herein, Class A, Class B
and Class C bear the expenses related to the distribution of their respective
shares.
 
    The Fund is not required to hold Annual Meetings of Shareholders and in
ordinary circumstances the Fund does not intend to hold such meetings. The
Trustees may call Special Meetings of Shareholders for action by shareholder
vote as may be required by the Act or the Declaration of Trust. Under certain
circumstances the Trustees may be removed by action of the Trustees or by the
shareholders.
 
    Under Massachusetts law, shareholders of a business trust may, under certain
limited circumstances, be held personally liable as partners for obligations of
the Fund. However, the Declaration of Trust contains an express disclaimer of
shareholder liability for acts or obligations of the Fund, requires that Fund
obligations include such disclaimer, and provides for indemnification and
reimbursement of expenses out of the Fund's property for any shareholder held
personally liable for the obligations of the Fund. Thus, the risk of a
shareholder incurring financial loss on account of shareholder liability is
limited to circumstances in which the Fund itself would be unable to meet its
obligations. Given the above limitations on shareholder personal liability, and
the nature of the Fund's assets and operations, in the opinion of Massachusetts
counsel to the Fund, the risk to shareholders of personal liability is remote.
 
    CODE OF ETHICS.  The Adviser is subject to a Code of Ethics with respect to
investment transactions in which the Adviser's officers, directors and certain
other persons have a beneficial interest to avoid any actual or potential
conflict or abuse of their fiduciary position. The Code of Ethics, as it
pertains to the TCW/DW Funds, contains several restrictions and procedures
designed to eliminate conflicts of interest including: (a) pre-clearance of
personal investment transactions to ensure that personal transactions by
employees are not being conducted at the same time as the Adviser's clients; (b)
quarterly reporting of personal securities transactions; (c) a prohibition
against personally acquiring securities in an initial public offering, entering
into uncovered short sales and writing uncovered options; (d) a seven day
"black-out period" prior or subsequent to a TCW/DW Fund transaction during which
portfolio managers are prohibited from making certain transactions in securities
which are being purchased or sold by a TCW/DW Fund; (e) a prohibition, with
respect to certain investment personnel, from profiting in the purchase and
sale, or sale and purchase, of the same (or equivalent) securities within 60
calendar days; and (f) a prohibition against acquiring any security which is
subject to firm wide or, if applicable, a department restriction of the Adviser.
The Code of Ethics provides that exemptive relief may be given from certain of
its requirements, upon application. The Adviser's Code of Ethics complies with
regulatory requirements and, insofar as it relates to persons associated with
registered investment companies, the 1994 Report of the Advisory Group on
Personal Investing of the Investment Company Institute.

THE FUND AND ITS MANAGEMENT
- --------------------------------------------------------------------------------
 
THE FUND
 
The Fund is a trust of the type commonly known as a "Massachusetts business
trust" and was organized under the laws of the Commonwealth of Massachusetts on
March 2, 1993. The Fund is one of the TCW/DW Funds, which currently consist, in
addition to the Fund, of TCW/DW Core Equity Trust, TCW/DW North American
Government Income Trust, TCW/DW Latin American Growth Fund, TCW/DW Income and
Growth Fund, TCW/DW Small Cap Growth Fund, TCW/DW Term Trust 2000, TCW/DW Term
Trust 2002, TCW/DW Term Trust 2003, TCW/DW Emerging Markets Opportunities Trust,
TCW/DW Total Return Trust, TCW/ DW Mid-Cap Equity Trust, TCW/DW Global Telecom
Trust and TCW/DW Strategic Income Trust.
 
THE MANAGER
 
    Dean Witter Services Company Inc. (the "Manager"), a Delaware corporation,
whose address is Two World Trade Center, New York, New York 10048, is the Fund's
Manager. The Manager is a wholly-owned subsidiary of Dean Witter InterCapital
Inc. ("InterCapital"), a Delaware corporation. InterCapital is a wholly-owned
subsidiary of Morgan Stanley, Dean Witter, Discover & Co. ("MSDWD"), a Delaware
corporation. In an internal reorganization which took place in January, 1993,
InterCapital assumed the investment advisory, administrative and management
activities previously performed by the InterCapital Division of Dean Witter
Reynolds Inc. ("DWR"), a broker-dealer affiliate of the Manager. (As hereinafter
used in this Statement of Additional Information, the term "InterCapital" refers
to DWR's InterCapital Division prior to the internal reorganization and to Dean
Witter InterCapital Inc. thereafter.) The daily management of the Fund is
conducted by or under the direction of officers of the Fund and of the Manager
and Adviser (see below), subject to review by the Fund's Board of Trustees.
Information as to these Trustees and officers is contained under the caption
"Trustees and Officers."
 
    Pursuant to a management agreement (the "Management Agreement") with the
Manager, the Fund has retained the Manager to manage the Fund's business
affairs, supervise the overall day-to-day operations of the Fund (other than
rendering investment advice) and provide all administrative services to the
Fund. Under the terms of the Management Agreement, the Manager also maintains
certain of the Fund's books and furnishes, at its own expense, such office
space, facilities, equipment, supplies, clerical help and bookkeeping and legal
services as the Fund may reasonably require in the conduct of its business,
including the preparation of prospectuses, statements of additional information,
proxy statements and reports required to be filed with the federal and state
securities commissions (except insofar as the participation or assistance of
independent accountants and attorneys is, in the opinion of the Manager,
necessary or desirable). In addition, the Manager pays the salaries of all
personnel, including officers of the Fund, who are employees of the Manager. The
Manager also bears the cost of the Fund's telephone service, heat, light, power
and other utilities.
 
   
    As full compensation for the services and facilities furnished to the Fund
and expenses of the Fund assumed by the Manager, the Fund pays the Manager
monthly compensation calculated daily by applying the annual rate of 0.45% to
the Fund's daily net assets. While the total fees payable under the Management
Agreement and the Advisory Agreement (described below) are higher than that paid
by most other investment companies for similar services, the Board of Trustees
determined that the total fees payable under the Management Agreement and the
Advisory Agreement are reasonable in relation to the scope and quality of
services to be provided thereunder. In this regard, in evaluating the Management
Agreement and the Advisory Agreement, the Board of Trustees recognized that the
Manager and the Adviser had, pursuant to an agreement described under the
section entitled "The Adviser," agreed to a division as between themselves of
the total fees necessary for the management of the business affairs of and the
furnishing of investment advice to the Fund. Accordingly, in reviewing the
Management Agreement and Advisory Agreement, the Board viewed as most
significant the question as to whether the total fees payable under the
Management and Advisory Agreements were in the aggregate reasonable in relation
to the services to be provided thereunder. For the fiscal years ended September
30, 1995, September 30, 1996 and September 30, 1997, the Fund accrued to the
Manager total compensation under the Management Agreement of $541,070, $442,975
and $417,405, respectively. The management fee is allocated among the Classes
pro rata based on the net assets of the Fund attributable to each Class.
    
 
                                       3
<PAGE>
    The Management Agreement provides that in the absence of willful
misfeasance, bad faith, gross negligence or reckless disregard of its
obligations thereunder, the Manager is not liable to the Fund or any of its
investors for any act or omission by the Manager or for any losses sustained by
the Fund or its investors. The Management Agreement in no way restricts the
Manager from acting as manager to others.
 
    InterCapital paid the organizational expenses of the Fund incurred prior to
the offering of the Fund's shares. The Fund has reimbursed InterCapital for such
expenses of approximately $180,493. These expenses have been deferred and are
being amortized by the Fund on the straight line method over a period not to
exceed five years from the date of commencement of the Fund's operations.
 
    The Management Agreement was initially approved by the Trustees on June 4,
1994 and became effective on April 17, 1995. The Management Agreement replaced a
prior management agreement in effect between the Fund and Dean Witter Services
Company, Inc. which in turn replaced a prior management agreement in effect
between the Fund and InterCapital, the parent company of the Manager. The nature
and scope of services provided to the Fund, and the formula to determine fees
paid by the Fund under the Management Agreement, are identical to those of the
previous agreements. The Management Agreement may be terminated at any time,
without penalty, on thirty days' notice by the Trustees of the Fund or by the
Manager.
 
    Under its terms, the Management Agreement had an initial term ending April
30, 1995, and will continue in effect from year to year thereafter, provided
continuance of the Agreement is approved at least annually by the Trustees of
the Fund, including the vote of a majority of the Trustees of the Fund who are
not parties to the Management or Advisory Agreement or "interested persons" (as
defined in the Investment Company Act of 1940, as amended (the "Act")), of any
such party (the "Independent Trustees"). Most recent continuation of the
Management Agreement for one year, until April 30, 1998, was approved by the
Trustees, including a majority of the Independent Trustees, at their meeting on
April 24, 1997.
 
THE ADVISER
 
   
TCW Funds Management, Inc. (the "Adviser") is a wholly-owned subsidiary of The
TCW Group, Inc. ("TCW"), whose direct and indirect subsidiaries, including Trust
Company of the West and TCW Asset Management Company, provide a variety of
trust, investment management and investment advisory services. As of September
30, 1997, the Adviser and its affiliates had approximately $50 billion under
management or committed to management. The Adviser is headquartered at 865 South
Figueroa Street, Suite 1800, Los Angeles, California 90017 and is registered as
an investment adviser under the Investment Advisers Act of 1940. In addition to
the Fund, the Adviser serves as investment adviser to thirteen other TCW/DW
Funds: TCW/DW Core Equity Trust, TCW/DW North American Government Income Trust,
TCW/DW Latin American Growth Fund, TCW/DW Income and Growth Fund, TCW/DW Small
Cap Growth Fund, TCW/DW Term Trust 2000, TCW/DW Term Trust 2002, TCW/DW Term
Trust 2003, TCW/DW Emerging Markets Opportunities Trust, TCW/DW Total Return

Convertible Securities Fund, Inc., a closed-end investment company listed on the
New York Stock Exchange, and to TCW Galileo Funds, Inc., an open-end investment
company, and acts as adviser or sub-adviser to other investment companies.
    
 
    Robert A. Day, who is Chairman of the Board of Directors of TCW, 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 TCW.
 
    Pursuant to an investment advisory agreement (the "Advisory Agreement") with
the Adviser, the Fund has retained the Adviser to invest the Fund's assets,
including the placing of orders for the purchase and sale of portfolio
securities. The Adviser obtains and evaluates such information and advice
relating to the economy, securities markets, and specific securities as it
considers necessary or useful to continuously manage the assets of the Fund in a
manner consistent with its investment objective. In addition, the Adviser pays
the salaries of all personnel, including officers of the Fund, who are employees
of the Adviser.
 
    As full compensation for the services and facilities furnished to the Fund
and expenses of the Fund assumed by the Adviser, the Fund pays the Adviser
monthly compensation calculated daily by applying the
 
                                       4

annual rate of 0.30% to the Fund's daily net assets. For the fiscal years ended
September 30, 1995, 1996 and 1997, the Fund accrued to the Adviser total
compensation under the Advisory Agreement of $360,714, $295,317 and $278,270,
respectively. The advisory fee is allocated among the Classes pro rata based on
the net assets of the Fund attributable to each Class.
    
 
    The Advisory Agreement provides that in the absence of willful misfeasance,
bad faith, gross negligence or reckless disregard of its obligations thereunder,
the Adviser is not liable to the Fund or any of its investors for any act or
omission by the Adviser or for any losses sustained by the Fund or its
Investors. The Advisory Agreement in no way restricts the Adviser from acting as
investment adviser to others.
 
    The Advisory Agreement was initially approved by the Trustees on April 28,
1993 and by InterCapital as then sole shareholder on July 22, 1993. The Advisory
Agreement may be terminated at any time, without penalty, on thirty days' notice
by the Trustees of the Fund, by the holders of a majority, as defined in the
Act, of the outstanding shares of the Fund, or by the Adviser. The Agreement
will automatically terminate in the event of its assignment (as defined in the
Act).
 
    Under its terms, the Advisory Agreement had an initial term ending April 30,
1995, and will continue from year to year thereafter, provided continuance of
the Agreement is approved at least annually by the vote of the holders of a
majority, as defined in the Act, of the outstanding shares of the Fund, or by
the Trustees of the Fund; provided that in either event such continuance is
approved annually by the vote of a majority of the Independent Trustees of the
Fund, which vote must be cast in person at a meeting called for the purpose of
voting on such approval. At their meeting held on April 24, 1997, the Board of
Trustees, including all of the Independent Trustees, approved the most recent
continuation of the Advisory Agreement until April 30, 1998.
 
   
    Expenses not expressly assumed by the Manager under the Management
Agreement, by the Adviser under the Advisory Agreement or by the Distributor of
the Fund's shares, Dean Witter Distributors Inc. ("Distributors" or the
"Distributor") (see "The Distributor"), will be paid by the Fund. These expenses
will be allocated among the four classes of shares of the Fund (each, a Class)
pro rata based on the net assets of the Fund attributable to each Class, except
as described below. Such expenses include, but are not limited to: expenses of
the Plan of Distribution pursuant to Rule 12b-1 (the "12b-1 fee") (see "The
Distributor"); charges and expenses of any registrar; custodian, stock transfer
and dividend disbursing agent; brokerage commissions and securities transaction
costs; taxes; engraving and printing of share certificates; registration costs
of the Fund and its shares under federal and state securities laws; the cost and
expense of printing, including typesetting, and distributing Prospectuses and
Statements of Additional Information of the Fund and supplements thereto to the
Fund's shareholders; all expenses of shareholders' and Trustees' meetings and of
preparing, printing and mailing of proxy statements and reports to shareholders;
fees and travel expenses of Trustees or members of any advisory board or
committee who are not employees of the Manager or Adviser or any corporate
affiliate of either; all expenses incident to any dividend, withdrawal or
redemption options; charges and expenses of any outside service used for pricing
of the Fund's shares; fees and expenses of legal counsel, including counsel to
the Trustees who are not interested persons of the Fund or of the Manager or the
Adviser (not including compensation or expenses of attorneys who are employees
of the Manager or the Adviser) and independent accountants; membership dues of
industry associations; interest on Fund borrowings; postage; insurance premiums
on property or personnel (including officers and Trustees) of the Fund which
inure to its benefit; extraordinary expenses (including, but not limited to,
legal claims and liabilities and litigation costs and any indemnification
relating thereto); and all other costs of the Fund's operation. The 12b-1 fees
relating to a particular Class will be allocated directly to that Class. In
addition, other expenses associated with a particular Class (except advisory or
custodial fees) may be allocated directly to that Class, provided that such
expenses are reasonably identified as specifically attributable to that Class
and the direct allocation to that Class is approved by the Trustees.
    
 
    DWR and TCW have entered into an Agreement for the purpose of creating,
managing, administering and distributing a family of investment companies and
other managed pooled investment vehicles offered on a retail basis within the
United States. The Agreement contemplates that, subject to approval of the board
of trustees or directors of a particular investment entity, DWR or its
affiliates will provide management and distribution services and TCW or its
affiliates will provide investment advisory services for each such investment
entity.
 
                                       5

The Agreement sets forth the terms and conditions of the relationship between
TCW and its affiliates and DWR and its affiliates and the manner in which the
parties will implement the creation and maintenance of the investment entities,
including the parties' expectations as to respective allocation of fees to be
paid by an investment entity to each party for the services to be provided to it
by such party.
 
    The Fund has acknowledged that each of DWR and TCW owns its own name,
initials and logo. The Fund has agreed to change its name at the request of
either the Manager or the Adviser, or if the Management Agreement between the

is terminated.

THE BOARD OF TRUSTEES, THE INDEPENDENT TRUSTEES, AND THE COMMITTEES
 
   
    The Board of Trustees consists of nine (9) trustees. These same individuals
also serve as trustees for all of the TCW/DW Funds. As of the date of this
Statement of Additional Information, there are a total of 14 TCW/ DW Funds. As
of October 31, 1997, the TCW/DW Funds had total net assets of approximately $4.4
billion and approximately a quarter of a million shareholders.
    
 
    Five Trustees (56% of the total number) have no affiliation or business
connection with TCW Funds Management, Inc. or Dean Witter Services Company Inc.
or any of their affiliated persons and do not own any stock or other securities
issued by MSDWD or TCW, the parent companies of Dean Witter Services Company
Inc. and TCW Funds Management, Inc., respectively. These are the "disinterested"
or "independent" Trustees. The other four Trustees (the "management Trustees")
are affiliated with either Dean Witter Services Company Inc. or TCW. Four of the
five independent Trustees are also Independent Trustees of the Dean Witter
Funds.
 
    Law and regulation establish both general guidelines and specific duties for
the Independent Trustees. The TCW/DW Funds seek as Independent Trustees
individuals of distinction and experience in business and finance, government
service or academia; these are people whose advice and counsel are in demand by
others and for whom there is often competition. To accept a position on the
Funds' Boards, such individuals may reject other attractive assignments because
the Funds make substantial demands on their time. Indeed, by serving on
 
                                       9
<PAGE>
the Funds' Boards, certain Trustees who would otherwise be qualified and in
demand to serve on bank boards would be prohibited by law from doing so.
 
    All of the Independent Trustees serve as members of the Audit Committee and
the Committee of the Independent Trustees. Three of them also serve as members
of the Derivatives Committee. During the calendar year ended December 31, 1996,
the three Committees held a combined total of fifteen meetings. The Committees
hold some meetings at the offices of the Manager or Adviser and some outside
those offices. Management Trustees or officers do not attend these meetings
unless they are invited for purposes of furnishing information or making a
report.
 
    The Committee of the Independent Trustees is charged with recommending to
the full Board approval of management, advisory and administration contracts,
Rule 12b-1 plans and distribution and underwriting agreements; continually
reviewing Fund performance; checking on the pricing of portfolio securities,
brokerage commissions, transfer agent costs and performance, and trading among
Funds in the same complex; and approving fidelity bond and related insurance
coverage and allocations, as well as other matters that arise from time to time.
The Independent Trustees are required to select and nominate individuals to fill
any Independent Trustee vacancy on the Board of any Fund that has a Rule 12b-1
plan of distribution. Each of the open-end TCW/DW Funds has such a plan.
 
    The Audit Committee is charged with recommending to the full Board the
engagement or discharge of the Fund's independent accountants; directing
investigations into matters within the scope of the independent accountants'
duties, including the power to retain outside specialists; reviewing with the
independent accountants the audit plan and results of the auditing engagement;
approving professional services provided by the independent accountants and
other accounting firms prior to the performance of such services; reviewing the
independence of the independent accountants; considering the range of audit and
non-audit fees; reviewing the adequacy of the Fund's system of internal
controls; and preparing and submitting Committee meeting minutes to the full
Board.
 
    Finally, the Board of each Fund has formed a Derivatives Committee to
establish parameters for and oversee the activities of the Fund with respect to
derivative investments, if any, made by the Fund.
 
DUTIES OF CHAIRMAN OF COMMITTEE OF THE INDEPENDENT TRUSTEES AND AUDIT COMMITTEE
 
    On July 1, 1996, Mr. Haire became Chairman of the Committee of the
Independent Trustees and the Audit Committee of the TCW/DW Funds. The Chairman
of the Committees maintains an office at the Funds' headquarters in New York. He
is responsible for keeping abreast of regulatory and industry developments and
the Funds' operations and management. He screens and/or prepares written
materials and identifies critical issues for the Independent Trustees to
consider, develops agendas for Committee meetings, determines the type and
amount of information that the Committees will need to form a judgment on
various issues, and arranges to have that information furnished to Committee
members. He also arranges for the services of independent experts and consults
with them in advance of meetings to help refine reports and to focus on critical
issues. Members of the Committees believe that the person who serves as Chairman
of both Committees and guides their efforts is pivotal to the effective
functioning of the Committees.
 
    The Chairman of the Committees also maintains continuous contact with the
Funds' management, with independent counsel to the Independent Trustees and with
the Funds' independent auditors. He arranges for a series of special meetings
involving the annual review of investment advisory, management and other
operating contracts of the Funds and, on behalf of the Committees, conducts
negotiations with the Investment Adviser and the Manager and other service
providers. In effect, the Chairman of the Committees serves as a combination of
chief executive and support staff of the Independent Trustees.
 
    The Chairman of the Committee of the Independent Trustees and the Audit
Committee is not employed by any other organization and devotes his time
primarily to the services he performs as Committee Chairman and Independent
Trustee of the TCW/DW Funds and as Chairman of the Committee of the Independent
Trustees and the Audit Committee and Independent Director or Trustee of the Dean
Witter Funds. The current Committee Chairman has had more than 35 years
experience as a senior executive in the investment company industry.

ADVANTAGES OF HAVING SAME INDIVIDUALS AS INDEPENDENT TRUSTEES FOR ALL TCW/DW
FUNDS
 
    The Independent Trustees and the Funds' management believe that having the
same Independent Trustees for each of the TCW/DW Funds avoids the duplication of
effort that would arise from having different groups of individuals serving as
Independent Trustees for each of the Funds or even of sub-groups of Funds. They
believe that having the same individuals serve as Independent Trustees of all
the Funds tends to increase their knowledge and expertise regarding matters
which affect the Fund complex generally and enhances their ability to negotiate
on behalf of each Fund with the Fund's service providers. This arrangement also
precludes the possibility of separate groups of Independent Trustees arriving at
conflicting decisions regarding operations and management of the Funds and
avoids the cost and confusion that would likely ensue. Finally, having the same
Independent Trustees serve on all Fund Boards enhances the ability of each Fund
to obtain, at modest cost to each separate Fund, the services of Independent
Trustees, and a Chairman of their Committees, of the caliber, experience and
business acumen of the individuals who serve as Independent Trustees of the
TCW/DW Funds.
 
COMPENSATION OF INDEPENDENT TRUSTEES
 
   
    The Fund pays each Independent Trustee an annual fee of $2,225 plus a per
meeting fee of $200 for meetings of the Board of Trustees or committees of the
Board of Trustees attended by the Trustee (the Fund pays the Chairman of the
Audit Committee an annual fee of $750 and pays the Chairman of the Committee of
the Independent Trustees an additional annual fee of $1,200). If a Board meeting
and a Committee meeting, or more than one Committee meeting, take place on a
single day, the Trustees are paid a single meeting fee by the Fund. The Fund
also reimburses such Trustees for travel and other out-of-pocket expenses
incurred by them in connection with attending such meetings. Trustees and
officers of the Fund who are or have been employed by the Manager or the Adviser
or an affiliated company of either receive no compensation or expense
reimbursement from the Fund. The Trustees of the TCW/DW Funds do not have
retirement or deferred compensation plans.

Independent Trustees by the Fund for the fiscal year ended September 30, 1997.

    As of the date of this Statement of Additional Information, 57 of the Dean
Witter Funds have adopted a retirement program under which an Independent
Trustee who retires after serving for at least five years (or such lesser period
as may be determined by the Board) as an Independent Director or Trustee of any
Dean Witter Fund that has adopted the retirement program (each such Fund
referred to as an "Adopting Fund" and each such Trustee referred to as an
"Eligible Trustee") is entitled to retirement payments upon reaching the
eligible retirement age (normally, after attaining age 72). Annual payments are
based upon length of service. Currently, upon retirement, each Eligible Trustee
is entitled to receive from the Adopting Fund, commencing as of his or her
retirement date and continuing for the remainder of his or her life, an annual
retirement benefit (the "Regular Benefit") equal to 25.0% of his or her Eligible
Compensation plus 0.4166666% of such Eligible Compensation for each full month
of service as an Independent Director or Trustee of any Adopting Fund in excess
of five years up to a maximum of 50.0% after ten years of service. The foregoing
percentages may be changed by the Board.(1) "Eligible Compensation" is one-fifth
of the total compensation earned by such Eligible Trustee for service to the
Adopting Fund in the five year period prior to the date of the Eligible
Trustee's retirement. Benefits under the retirement program are not secured or
funded by the Adopting Funds.
 
- ---------------
(1) An Eligible Trustee may elect alternate payments of his or her retirement
    benefits based upon the combined life expectancy of such Eligible Trustee
    and his or her spouse on the date of such Eligible Trustee's retirement. The
    amount estimated to be payable under this method, through the remainder of
    the later of the lives of such Eligible Trustee and spouse, will be the
    actuarial equivalent of the Regular Benefit. In addition, the Eligible
    Trustee may elect that the surviving spouse's periodic payment of benefits
    will be equal to either 50% or 100% of the previous periodic amount, an
    election that, respectively, increases or decreases the previous periodic
    amount so that the resulting payments will be the actuarial equivalent of
    the Regular Benefit.

INVESTMENT PRACTICES AND POLICIES
- --------------------------------------------------------------------------------
 
U.S. GOVERNMENT SECURITIES
 
    As discussed in the Prospectus, the Fund may invest in, among other
securities, securities issued by the U.S. Government, its agencies or
instrumentalities. Such securities include:
 
       (1) U.S. Treasury bills (maturities of one year or less), U.S. Treasury
    notes (maturities of one to ten years) and U.S. Treasury bonds (generally
    maturities of greater than ten years), all of which are direct obligations
    of the U.S. Government and, as such, are backed by the "full faith and
    credit" of the United States.
 
       (2) Securities issued by agencies and instrumentalities of the U.S.
    Government which are backed by the full faith and credit of the United
    States. Among the agencies and instrumentalities issuing such obligations
    are the Federal Housing Administration, the Government National Mortgage
    Association ("GNMA"), the Department of Housing and Urban Development, the
    Export-Import Bank, the Farmers Home Administration, the General Services
    Administration, the Maritime Administration and the Small Business
    Administration. The maturities of such obligations range from three months
    to 30 years.
 
       (3) Securities issued by agencies and instrumentalities which are not
    backed by the full faith and credit of the United States, but whose issuing
    agency or instrumentality has the right to borrow, to meet its obligations,
    from an existing line of credit with the U.S. Treasury. Among the agencies
    and instrumentalities issuing such obligations are the Tennessee Valley
    Authority, the Federal National Mortgage Association ("FNMA"), the Federal
    Home Loan Mortgage Corporation ("FHLMC") and the U.S. Postal Service.
 
       (4) Securities issued by agencies and instrumentalities which are not
    backed by the full faith and credit of the United States, but which are
    backed by the credit of the issuing agency or instrumentality. Among the
    agencies and instrumentalities issuing such obligations are the Federal Farm
    Credit System and the Federal Home Loan Banks.
 
    Neither the value nor the yield of the U.S. Government securities which may
be invested in by the Fund are guaranteed by the U.S. Government. Such values
and yield will fluctuate with changes in prevailing
 
                                       13
<PAGE>
interest rates and other factors. Generally, as prevailing interest rates rise,
the value of any U.S. Government securities held by the Fund will fall. Such
securities with longer maturities generally tend to produce higher yields and
are subject to greater market fluctuation as a result of changes in interest
rates than debt securities with shorter maturities. The Fund is not limited as
to the maturities of the U.S. Government securities in which it may invest.
 
MORTGAGE-BACKED SECURITIES
 
    As discussed in the Prospectus, the Fund may invest in, among other
securities, fixed-rate and adjustable rate mortgage-backed securities
("Mortgage-Backed Securities").
 
    There are currently three basic types of Mortgage-Backed Securities: (i)
those issued or guaranteed by the United States Government or one of its
agencies or instrumentalities, such as the Government National Mortgage
Association ("GNMA"), the Federal National Mortgage Association ("FNMA") and the
Federal Home Loan Mortgage Corporation ("FHLMC") (securities issued by GNMA, but
not those issued by FNMA or FHLMC, are backed by the "full faith and credit" of
the United States); (ii) those issued by private issuers that represent an
interest in or are collateralized by Mortgage-Backed Securities issued or
guaranteed by the United States Government or one of its agencies or
instrumentalities; and (iii) those issued by private issuers that represent an
interest in or are collateralized by whole mortgage loans or Mortgage-Backed
Securities without a government guarantee but usually having some form of
private credit enhancement.
 
    The Fund may invest in mortgage pass-through securities representing
participation interests in pools of residential mortgage loans originated by
United States governmental or private lenders such as banks, broker-dealers and
financing corporations and guaranteed, to the extent provided in such
securities, by the United States Government or one of its agencies or
instrumentalities. 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
semi-annually) and principal payments at maturity or on specified call dates.
Mortgage pass-through securities provide for monthly payments 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 Fund 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 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.
 
    ADJUSTABLE RATE MORTGAGE SECURITIES.  As stated in the Prospectus, the Fund
may also invest in adjustable rate mortgage securities ("ARMs"), which are
pass-through mortgage securities collateralized by mortgages with adjustable
rather than fixed rates. ARMs eligible for inclusion in a mortgage pool
generally provide for a fixed initial mortgage interest rate for either the
first three, six, twelve or thirteen scheduled monthly payments. Thereafter, the
interest rates are subject to periodic adjustment based on changes to a
designated benchmark index.
 
    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
 
                                       14
<PAGE>
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.
 
    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 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.
 
    COLLATERALIZED MORTGAGE OBLIGATIONS AND MULTICLASS PASS-THROUGH
SECURITIES.  As stated in the Prospectus, the Fund may invest up to 5% of its
net assets in collateralized mortgage obligations or "CMOs." 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 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 agencies or instrumentalities of
the United States government, 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 interests in the
underlying assets of the REMICs themselves. However, there are no effects on the
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
REMICs.
 
    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 semi-annual basis. Certain CMOs may have variable or floating
interest rates and others may be stripped (securities which provide only the
principal or interest feature of the underlying security).
 
    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 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 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 Fund also may invest in, among other things, parallel pay CMOs and
Planned Amortization Class CMOs ("PAC Bonds"). Parallel pay CMOs are structured
to provide payments of principal on each payment date to more than one class.
These simultaneous payments are taken into account in calculating the stated
maturity date or final distribution date of each class, which, as with other CMO
structures, must be retired by
 
                                       15
<PAGE>
its stated maturity date or final distribution date but may be retired earlier.
PAC Bonds generally require payments of a specified amount of principal on each
payment date. PAC Bonds always are parallel pay CMOs with the required principal
payment on such securities having the highest priority after interest has been
paid to all classes.
 
    RISKS OF MORTGAGE-BACKED AND ASSET-BACKED SECURITIES.  Mortgage-Backed and
Asset-Backed Securities have certain different characteristics than traditional
debt securities. Among the major differences are that interest and principal
payments are made more frequently, usually monthly, and that principal may be
prepaid at any time because the underlying mortgage loans or other assets
generally may be prepaid at any time. As a result, if the Fund purchases such a
security at a premium, a prepayment rate that is faster than expected may reduce
yield to maturity, while a prepayment rate that is slower than expected may have
the opposite effect of increasing yield to maturity. Alternatively, if the Fund
purchases these securities at a discount, faster than expected prepayments will
increase, while slower than expected prepayments may reduce, yield to maturity.
The Fund may invest a portion of its assets in derivative Mortgage-Backed
Securities such as Stripped Mortgage-Backed Securities which are highly
sensitive to changes in prepayment and interest rates. The Adviser will seek to
manage these risks (and potential benefits) by investing in a variety of such
securities and through hedging techniques.
 
    Mortgage-Backed and Asset-Backed Securities, like all fixed income
securities, generally decrease in value as a result of increases in interest
rates. In addition, although generally the value of fixed-income securities
increases during periods of falling interest rates and, as stated above,
decreases during periods of rising interest rates, as a result of prepayments
and other factors, this is not always the case with respect to Mortgage-Backed
and Asset-Backed Securities.
 
    Although the extent of prepayments on a pool of mortgage loans depends on
various economic and other factors, as a general rule prepayments on fixed rate
mortgage loans will increase during a period of falling interest rates and
decrease during a period of rising interest rates. Accordingly, amounts
available for reinvestment by the Fund are likely to be greater during a period
of declining interest rates and, as a result, likely to be reinvested at lower
interest rates than during a period of rising interest rates. Asset-Backed
Securities, although less likely to experience the same prepayment rates as
Mortgage-Backed Securities, may respond to certain of the same factors
influencing prepayments, while at other times different factors, such as changes
in credit use and payment patterns resulting from social, legal and economic
factors, will predominate. Mortgage-Backed and Asset-Backed Securities generally
decrease in value as a result of increases in interest rates and may benefit
less than other fixed income securities from declining interest rates because of
the risk of prepayment.
 
    There are certain risks associated specifically with CMOs. CMOs issued by
private entities are not U.S. Government securities 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. However, as stated above, the Fund will invest only
in CMOs which are of investment grade or, if unrated, are determined to be of
comparable quality. Also, a number of different factors, including the extent of
prepayment of principal of the Mortgage Assets, affect the availability of cash
for principal payments by the CMO issuer on any payment date and, accordingly,
affect the timing of principal payments on each CMO class.
 
    Asset-Backed Securities involve certain risks that are not posed by
Mortgage-Backed Securities, resulting mainly from the fact that Asset-Backed
Securities do not usually contain the complete benefit of a security interest in
the related collateral. For example, credit card receivables generally are
unsecured and the debtors are entitled to the protection of a number of state
and federal consumer credit laws, some of which may reduce the ability to obtain
full payment. In the case of automobile receivables, due to various legal and
economic factors, proceeds from repossessed collateral may not always be
sufficient to support payments on these securities.
 
RISKS OF INTERNATIONAL INVESTING
 
    As stated in the Prospectus, the Fund may invest up to 25% of its total
assets in foreign securities. Investments in foreign securities will occasion
risks relating to political and economic developments abroad,
 
                                       16
<PAGE>
including the possibility of expropriations or confiscatory taxation,
limitations on the use or transfer of Fund assets and any effects of foreign
social, economic or political instability. Foreign securities are not subject to
the regulatory requirements of U.S. securities and, as such, there may be less
publicly available information about such securities. Moreover, foreign
securities are not subject to uniform accounting, auditing and financial
standards and requirements comparable to those applicable to U.S. securities.
 
    Securities of foreign issuers may be less liquid than comparable securities
of U.S. issuers and, as such, their price changes may be more volatile.
Furthermore, foreign exchanges and broker-dealers are generally subject to less
government and exchange scrutiny and regulation than their American
counterparts. Brokerage commissions, dealer concessions and other transaction
costs may be higher on foreign markets than in the U.S. In addition, differences
in clearance and settlement procedures on foreign markets may occasion delays in
settlements of Fund trades effected in such markets. Inability to dispose of
portfolio securities due to settlement delays could result in losses to the Fund
due to subsequent declines in value of such securities and the inability of the
Fund to make intended security purchases due to settlement problems could result
in a failure of the Fund to make potentially advantageous investments.
 
    Investments in foreign securities also involve currency risks. Fluctuations
in the relative rates of exchange among the currencies involved will affect the
value of the Fund's investments. Changes in foreign currency exchange rates
relative to the U.S. dollar will affect the U.S. dollar value of the Fund's
assets denominated in that currency and thereby impact upon the Fund's total
return on such assets.
 
    Foreign currency exchange rates are determined by forces of supply and
demand on the foreign exchange markets. These forces are themselves affected by
the international balance of payments and other economic and financial
conditions, government intervention, speculation and other factors. Moreover,
foreign currency exchange rates may be affected by the regulatory control of the
exchanges on which the currencies trade.
 
    As stated in the Prospectus, the Fund may invest up to 5% of its total
assets in Cetes, a type of Mexican government peso denominated debt securities.
Certain special considerations are associated with investing in debt obligations
of the Mexican government. The Mexican government has exercised and continues to
exercise a significant influence over many aspects of the private sector in
Mexico. Mexican government actions concerning the economy could have a
significant effect on market conditions and prices and yields of Mexican debt
obligations, including those in which the Fund invests. Mexico is currently the
second largest debtor nation (among developing countries) to commercial banks
and foreign governments. The value of the Fund's portfolio investments may be
affected by changes in oil prices, interest rates, taxation and other political
or economic developments in Mexico, including recent rates of inflation which
have exceeded the rates of inflation in the United States.
 
MONEY MARKET SECURITIES
 
    As stated in the Prospectus, the U.S. money market instruments which the
Fund may purchase include U.S. Government securities, bank obligations,
Eurodollar certificates of deposit, obligations of savings institutions, fully
insured certificates of deposit and commercial paper. Such securities 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.  Obligations (including certificates of deposit and
bankers' acceptances) 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 to the extent below;
 
    EURODOLLAR CERTIFICATES OF DEPOSIT.  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);
 
                                       17
<PAGE>
    OBLIGATIONS OF SAVINGS INSTITUTIONS.  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.  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 net assets in all such obligations
and in all illiquid assets, in the aggregate; and
 
    COMMERCIAL PAPER.  Commercial paper rated within the two highest grades by
Standard & Poor's Corporation or the highest grade by Moody's Investors Service,
Inc. or, if not rated, issued by a company having an outstanding debt issue
rated at least AAA by Standard & Poor's or Aaa by Moody's.
 
REPURCHASE AGREEMENTS
 
    When cash may be available for only a few days, it may be invested by the
Fund in repurchase agreements until such time as it may otherwise be invested or
used for payments of obligations of the Fund. These agreements, which may be
viewed as a type of secured lending by the Fund, typically involve the
acquisition by the Fund of debt securities from a selling financial institution
such as a bank, savings and loan association or broker-dealer. The agreement
provides 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 will be marked-to-market daily to determine that the
value of the collateral, as specified in the agreement, does not decrease below
the purchase price plus accrued interest. If such 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 time when the repurchase is to occur. Although such date
is deemed by the Fund to be the maturity date of a repurchase agreement, the
maturities of securities subject to repurchase agreements are not subject to any
limits.
 
    While repurchase agreements involve certain risks not associated with direct
investments in debt securities, the Fund follows procedures designed to minimize
such risks. These procedures include effecting repurchase transactions only with
large, well-capitalized and well-established financial institutions whose
financial condition will be continually monitored by the Adviser subject to
procedures established by the Board of Trustees of the Fund. In addition, as
described above, the value of the collateral underlying the repurchase agreement
will be at least equal to the repurchase price, including any accrued interest
earned on the repurchase agreement. In the event of a default or bankruptcy by a
selling financial institution, the Fund will seek to liquidate such collateral.
However, the exercising of the Fund's right to liquidate such collateral could
involve certain costs or delays and, to the extent that proceeds from any sale
upon a default of the obligation to repurchase were less than the repurchase
price, the Fund could suffer a loss. It is the current policy of the Fund not to
invest in repurchase agreements that do not mature within seven days if any such
investment, together with any other illiquid assets held by the Fund, amounts to
more than 15% of its net assets.
 
REVERSE REPURCHASE AGREEMENTS AND DOLLAR ROLLS
 
    The Fund may also use reverse repurchase agreements and dollar rolls with
respect to up to 5% of its total assets as part of its investment strategy.
Reverse repurchase agreements involve sales by the Fund of portfolio assets
concurrently with an agreement by the Fund to repurchase the same assets at a
later date at a fixed price. During the reverse repurchase agreement period, the
Fund continues to receive principal and interest payments on these securities.
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.
 
    The Fund may enter into dollar rolls in which the Fund sells securities for
delivery in the current month and simultaneously contracts to repurchase
substantially similar (same type and coupon) securities on a
 
                                       18
<PAGE>
specified future date. During the roll period, the Fund foregoes principal and
interest paid on the securities. The Fund is compensated by the difference
between the current sales price and the lower forward price for the future
purchase (often referred to as the "drop") as well as by the interest earned on
the cash proceeds of the initial sale.
 
    The Fund will establish a segregated account with its custodian bank in
which it will maintain cash, U.S. Government securities or other liquid
portfolio securities equal in value to its obligations in respect of reverse
repurchase agreements and dollar rolls. Reverse repurchase agreements and dollar
rolls involve the risk that the market value of the securities the 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 dollar roll files for bankruptcy or becomes insolvent, the Fund's use of the
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 dollar rolls are
speculative techniques involving leverage, and are considered borrowings by the
Fund.
 
WARRANTS
 
    The Fund may invest up to 5% of the value of its net assets in warrants,
including not more than 2% in warrants not listed on either the New York or
American Stock Exchange. Warrants are, in effect, an option to purchase equity
securities at a specific price, generally valid for a specific period of time,
and have no voting rights, pay no dividends and have no rights with respect to
the corporations issuing them. The Fund may acquire warrants attached to other
securities without reference to the foregoing limitations.
 
WHEN-ISSUED AND DELAYED DELIVERY SECURITIES AND FORWARD COMMITMENTS
 
    From time to time, in the ordinary course of business, the Fund 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 the 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
the 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. The Fund will also establish a segregated
account with the Fund's custodian bank in which it will continuously maintain
cash or U.S. Government securities or other liquid portfolio securities equal in
value to commitments to purchase securities on a when-issued, delayed delivery
or forward commitment basis; subject to this requirement, the 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-issued or
delayed delivery basis may increase the volatility of the Fund's net asset
value.
 
WHEN, AS AND IF ISSUED SECURITIES
 
    The Fund 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
occur within five 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. The 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
 
                                       19
<PAGE>
volatility of its net asset value. The 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.
 
FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS.
 
    As discussed in the Prospectus, the Fund may enter into forward foreign
currency exchange contracts ("forward contracts") as a hedge against
fluctuations in future foreign exchange rates. The Fund will conduct its foreign
currency exchange transactions either on a spot (i.e., cash) basis at the spot
rate prevailing in the foreign currency exchange market, or through entering
into forward contracts to purchase or sell foreign currencies. A forward
contract involves an obligation to purchase or sell a specific currency at a
future date, which may be any fixed number of days from the date of the contract
agreed upon by the parties, at a price set at the time of the contract. These
contracts are traded in the interbank market conducted directly between currency
traders (usually large, commercial and investment banks) and their customers.
Such forward contracts will only be entered into with United States banks and
their foreign branches or foreign banks whose assets total $1 billion or more. A
forward contract generally has no deposit requirement, and no commissions are
charged at any stage for trades.
 
    The Fund will enter into forward contracts under various circumstances. When
the Fund enters into a contract for the purchase or sale of a security
denominated in a foreign currency, it may, for example, desire to "lock in" the
price of the security in U.S. dollars or some other foreign currency which the
Fund is temporarily holding in its portfolio. By entering into a forward
contract for the purchase or sale, for a fixed amount of dollars or other
currency, of the amount of foreign currency involved in the underlying security
transactions, the Fund will be able to protect itself against a possible loss
resulting from an adverse change in the relationship between the U.S. dollar or
other currency which is being used for the security purchase and the foreign
currency in which the security is denominated during the period between the date
on which the security is purchased or sold and the date on which payment is made
or received.
 
    At other times, when, for example, the Adviser believes that the currency of
a particular foreign country may suffer a substantial decline against the U.S.
dollar or some other foreign currency, the Fund may enter into a forward
contract to sell, for a fixed amount of dollars or other currency, the amount of
foreign currency approximating the value of some or all of the Fund's securities
holdings (or securities which the Fund has purchased for its portfolio)
denominated in such foreign currency. Under identical circumstances, the Fund
may enter into a forward contract to sell, for a fixed amount of U.S. dollars or
other currency, an amount of foreign currency other than the currency in which
the securities to be hedged are denominated approximating the value of some or
all of the portfolio securities to be hedged. This method of hedging, called
"cross-hedging," will be selected by the Adviser when it is determined that the
foreign currency in which the portfolio securities are denominated has
insufficient liquidity or is trading at a discount as compared with some other
foreign currency with which it tends to move in tandem.
 
    In addition, when the Adviser anticipates purchasing securities at some time
in the future, and wishes to lock in the current exchange rate of the currency
in which those securities are denominated against the U.S. dollar or some other
foreign currency, the Fund may enter into a forward contract to purchase an
amount of currency equal to some or all of the value of the anticipated
purchase, for a fixed amount of U.S. dollars or other currency. The Fund may,
however, close out the forward contract without purchasing the security which
was the subject of the "anticipatory" hedge.
 
    The Fund will not enter into such forward contracts or maintain a net
exposure to such contracts where the consummation of the contracts would
obligate the Fund to deliver an amount of foreign currency in excess of the
value of the Fund's portfolio securities or other assets denominated in that
currency. Under normal circumstances, consideration of the prospect for currency
parities will be incorporated into the longer term investment decisions made
with regard to overall diversification strategies. However, the management of
the Fund believes that it is important to have the flexibility to enter into
such forward contracts when it determines that the best interests of the Fund
will be served. The Fund's custodian bank will place cash, U.S. Government
securities or other appropriate liquid portfolio securities in a segregated
account of the Fund in an amount equal to the value of the Fund's total assets
committed to the consummation of forward contracts entered into under
 
                                       20
<PAGE>
the circumstances set forth above. If the value of the securities placed in the
segregated account declines, additional cash or securities will be placed in the
account on a daily basis so that the value of the account will equal the amount
of the Fund's commitments with respect to such contracts.
 
    Where, for example, the Fund is hedging a portfolio position consisting of
foreign fixed-income securities denominated in a foreign currency against
adverse exchange rate moves vis-a-vis the U.S. dollar, at the maturity of the
forward contract for delivery by the Fund of a foreign currency, the Fund may
either sell the portfolio security and make delivery of the foreign currency, or
it may retain the security and terminate its contractual obligation to deliver
the foreign currency by purchasing an "offsetting" contract with the same
currency trader obligating it to purchase, on the same maturity date, the same
amount of the foreign currency (however, the ability of the Fund to terminate a
contract is contingent upon the willingness of the currency trader with whom the
contract has been entered into to permit an offsetting transaction). It is
impossible to forecast the market value of portfolio securities at the
expiration of the contract. Accordingly, it may be necessary for the Fund to
purchase additional foreign currency on the spot market (and bear the expense of
such purchase) if the market value of the security is less than the amount of
foreign currency the Fund is obligated to deliver and if a decision is made to
sell the security and make delivery of the foreign currency. Conversely, it may
be necessary to sell on the spot market some of the foreign currency received
upon the sale of the portfolio securities if its market value exceeds the amount
of foreign currency the Fund is obligated to deliver.
 
    If the Fund retains the portfolio securities and engages in an offsetting
transaction, the Fund will incur a gain or loss to the extent that there has
been movement in spot or forward contract prices. If the Fund engages in an
offsetting transaction, it may subsequently enter into a new forward contract to
sell the foreign currency. Should forward prices decline during the period
between the Fund's entering into a forward contract for the sale of a foreign
currency and the date it enters into an offsetting contract for the purchase of
the foreign currency, the Fund will realize a gain to the extent the price of
the currency it has agreed to sell exceeds the price of the currency it has
agreed to purchase. Should forward prices increase, the Fund will suffer a loss
to the extent the price of the currency it has agreed to purchase exceeds the
price of the currency it has agreed to sell.
 
    If the Fund purchases a fixed-income security which is denominated in U.S.
dollars but which will pay out its principal based upon a formula tied to the
exchange rate between the U.S. dollar and a foreign currency, it may hedge
against a decline in the principal value of the security by entering into a
forward contract to sell an amount of the relevant foreign currency equal to
some or all of the principal value of the security.
 
    At times when the Fund has written a call or put option on a fixed-income
security or the currency in which it is denominated, it may wish to enter into a
forward contract to purchase or sell the foreign currency in which the security
is denominated. A forward contract would, for example, hedge the risk of the
security on which a call option has been written declining in value to a greater
extent than the value of the premium received for the option. The Fund will
maintain with its Custodian at all times, cash, U.S. Government securities, or
other appropriate liquid portfolio securities in a segregated account equal in
value to all forward contract obligations and option contract obligations
entered into in hedge situations such as this.
 
    Although the Fund values its assets daily in terms of U.S. dollars, it does
not intend to convert its holdings of foreign currencies into U.S. dollars on a
daily basis. It will, however, do so from time to time, and investors should be
aware of the costs of currency conversion. Although foreign exchange dealers do
not charge a fee for conversion, they do realize a profit based on the spread
between the prices at which they are buying and selling various currencies. Thus
a dealer may offer to sell a foreign currency to the Fund at one rate, while
offering a lesser rate of exchange should the Fund desire to resell that
currency to the dealer.
 
    The Fund generally will not enter into a forward contract with a term of
greater than one year, although it may enter into forward contracts for periods
of up to five years. The Fund may be limited in its ability to enter into
hedging transactions involving forward contracts by the Internal Revenue Code
requirements relating to qualifications as a regulated investment company.
 
OPTIONS AND FUTURES TRANSACTIONS
 
    The Fund may write covered call options against securities held in its
portfolio and covered put options on eligible portfolio securities and stock
indexes and purchase options of the same series to effect closing
 
                                       21
<PAGE>
transactions, and may hedge against potential changes in the market value of
investments (or anticipated investments) and facilitate the reallocation of the
Fund's assets into and out of equities and fixed-income securities by purchasing
put and call options on portfolio (or eligible portfolio) securities and
engaging in transactions involving futures contracts and options on such
contracts.
 
    Call and put options on U.S. Treasury notes, bonds and bills and equity
securities are listed on Exchanges and are written in over-the-counter
transactions ("OTC options"). Listed options are issued by the Options Clearing
Corporation ("OCC") and other clearing entities including foreign exchanges.
Ownership of a listed call option gives the Fund the right to buy from the OCC
the underlying security covered by the option at the stated exercise price (the
price per unit of the underlying security) by filing an exercise notice prior to
the expiration date of the option. The writer (seller) of the option would then
have the obligation to sell to the OCC the underlying security at that exercise
price prior to the expiration date of the option, regardless of its then current
market price. Ownership of a listed put option would give the Fund the right to
sell the underlying security to the OCC at the stated exercise price. Upon
notice of exercise of the put option, the writer of the put would have the
obligation to purchase the underlying security from the OCC at the exercise
price.
 
    OPTIONS ON TREASURY BONDS AND NOTES.  Because trading 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 obligations by acquiring and holding the
underlying security. However, if the 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, the Fund will hold
the Treasury bills in a segregated account with its Custodian, so that they will
be treated as being covered.
 
    OTC OPTIONS.  Exchange-listed options are issued by the OCC (in the U.S.) or
other clearing entity 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 the Fund. With OTC options, such variables as expiration date, exercise
price and premium will be agreed upon between the Fund and the transacting
dealer, without the intermediation of a third party such as the OCC. If the
transacting dealer fails to make or take delivery of the securities underlying
an option it has written, in accordance with the terms of that option, the Fund
would lose the premium paid for the option as well as any anticipated benefit of
the transaction. The Fund will engage in OTC option transactions only with
primary U.S. Government securities dealers recognized by the Federal Reserve
Bank of New York.
 
    COVERED CALL WRITING.  The Fund is permitted to write covered call options
on portfolio securities, without limit, in order to aid in achieving its
investment objective. Generally, a call option is "covered" if the 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 subject to the option except that in the case
of call options on U.S. Treasury Bills, the 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 securities deliverable under the call option. A
call option is also covered if the Fund holds a call on the same security as the
underlying security 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 mark 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 with its Custodian.
 
                                       22
<PAGE>
    The Fund will receive 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 the Fund to achieve a greater total return than would be
realized from holding the underlying securities alone. Moreover, the income
received from the premium will offset a portion of the potential loss incurred
by the Fund if the securities underlying the option are ultimately sold by the
Fund at a loss. The income received from premiums will fluctuate with varying
economic market conditions. If the market value of the portfolio securities upon
which call options have been written increases, the Fund may receive less 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,
the Fund may be required, at any time, to deliver the underlying security
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 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 from being called,
to permit the sale of an underlying security or to enable the Fund to write
another call option on the underlying security with either a different exercise
price or expiration date or both. Also, effecting a closing purchase transaction
will permit the cash or proceeds from the concurrent sale of any securities
subject to the option to be used for other investments by the Fund. The 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.
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.
 
    If a call option expires unexercised, the 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 during
the option period. If a call option is exercised, the Fund realizes a gain or
loss from the sale of the underlying security equal to the difference between
the purchase price of the underlying security and the proceeds of the sale of
the security plus the premium received for on the option less the commission
paid.
 
    Options written by a Fund normally have expiration dates of from up to nine
months (equity securities) to eighteen months (fixed-income securities) from the
date written. The exercise price of a call option may be below, equal to or
above the current market value of the underlying security at the time the option
is written. See "Risks of Options and Futures Transactions," below.
 
    COVERED PUT WRITING.  As a writer of a covered put option, the 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 the 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 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 mark 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,
the Fund assumes the risk of loss should the market value of the underlying
security 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
 
                                       23
<PAGE>
price against delivery of the underlying security. The operation of and
limitations on covered put options in other respects are substantially identical
to those of call options.
 
    The Fund will write put options for two purposes: (1) to receive the income
derived from the premiums paid by purchasers; and (2) when the Adviser wishes to
purchase the security 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. 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 difference between
the exercise price of the option and the current market price of the underlying
securities when the put is exercised, offset by the premium received (less the
commissions paid on the transaction).
 
    PURCHASING CALL AND PUT OPTIONS.  The Fund may purchase listed and OTC call
and put options in amounts equaling up to 5% of its total assets. The Fund may
purchase call options only in order to close out a covered call position (see
"Covered Call Writing" above) and to protect against an increase in price of a
security it anticipates purchasing. 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 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.
 
    The Fund may purchase put options on securities which it holds (or has the
right to acquire) in its portfolio only to protect itself against a decline in
the value of the security. If the value of the underlying security 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, the Fund may sell a put option which it has previously purchased prior
to the sale of the securities underlying such option. Such a sale would result
in a net gain or loss depending on 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. Any such gain or loss could be offset in whole or in part by a
change in the market value of the underlying security. If a put option purchased
by the Fund expired without being sold or exercised, the premium would be lost.
 
    RISKS OF OPTIONS TRANSACTIONS.  The successful use of options depends on the
ability of the Adviser to forecast correctly interest rates and market
movements. If the market value of the portfolio securities upon which call
options have been written increases, the 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. 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 increase, but has retained the risk of loss
should the price of the underlying security decline. The covered put writer also
retains the risk of loss should the market value of the underlying security
decline below the exercise price of the option less the premium received on the
sale of the option. In both cases, the writer has no control over the time when
it may be required to fulfill its obligation as a writer of the option. Once an
option writer has received an exercise notice, it cannot effect a closing
purchase transaction in order to terminate its obligation under the option and
must deliver or receive the underlying securities at the exercise price.
 
    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 over-the-counter 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 covered put option writer who is
unable to effect a closing purchase transaction or to purchase an offsetting
over-the-counter 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 covered put writer would be unable to utilize the amount held in
cash or U.S. Government or other liquid portfolio securities as security for the
put option for other investment purposes until the exercise or expiration of the
option.
 
    The Fund's ability to close out its position as a writer of an option is
dependent upon the existence of a liquid secondary market on option Exchanges.
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
 
                                       24
<PAGE>
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: (i) insufficient trading interest in certain options; (ii)
restrictions on transactions imposed by an Exchange; (iii) trading halts,
suspensions or other restrictions imposed with respect to particular classes or
series of options or underlying securities; (iv) interruption of the normal
operations on an Exchange; (v) inadequacy of the facilities of an Exchange or
the OCC to handle current trading volume; or (vi) 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 OCC as a result of trades on that
Exchange would generally continue to be exercisable in accordance with their
terms.
 
    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, the Fund would continue to
be required to make daily cash payments of variation margin on open futures
positions. In such situations, if the 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, the 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
the Fund's ability to effectively hedge its portfolio.
 
    In the event of the bankruptcy of a broker through which the Fund engages in
transactions in options, 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 the Fund, the Fund could experience a loss of all or part of the
value of the option. Transactions are entered into by the Fund only with brokers
or financial institutions deemed creditworthy by the Adviser.
 
    Each of the Exchanges has established limitations governing the maximum
number of call or put 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 the Fund may write.
 
    While the futures contracts and options transactions to be engaged in by the
Fund for the purpose of hedging the Fund's portfolio securities are not
speculative in nature, there are risks inherent in the use of such instruments.
One such risk which may arise in employing futures contracts to protect against
the price volatility of portfolio securities is that the prices of securities
and indexes subject to futures contracts (and thereby the futures contract
prices) may correlate imperfectly with the behavior of the cash prices of the
Fund's portfolio securities. Another such risk is that prices of interest rate
futures contracts may not move in tandem with the changes in prevailing interest
rates against which the Fund seeks a hedge. A correlation may also be distorted
by the fact that the futures market is dominated by short-term traders seeking
to profit from the difference between a contract or security price objective and
their cost of borrowed funds. Such distortions are generally minor and would
diminish as the contract approached maturity.
 
    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
 
                                       25
<PAGE>
price and rate movements can take place in the underlying markets that cannot be
reflected in the option markets.
 
    STOCK INDEX OPTIONS.  Options on stock indexes are similar to options on
stock except that, rather than the right to take or make delivery of stock at a
specified price, an option on a stock index gives the holder the right to
receive, upon exercise of the option, an amount of cash if the closing level of
the stock index upon which the option is based is greater than, in the case of a
call, or less than, in the case of a put, the exercise price of the option. This
amount of cash is equal to such difference between the closing price of the
index and the exercise price of the option expressed in dollars times a
specified multiple (the "multiplier"). The multiplier for an index option
performs a function similar to the unit of trading for a stock option. It
determines the total dollar value per contract of each point in the difference
between the exercise price of an option and the current level of the underlying
index. A multiplier of 100 means that a one-point difference will yield $100.
Options on different indexes may have different multipliers. The writer of the
option is obligated, in return for the premium received, to make delivery of
this amount. Unlike stock options, all settlements are in cash and a gain or
loss depends on price movements in the stock market generally (or in a
particular segment of the market) rather than the price movements in individual
stocks. Currently, options are traded on the S&P 100 Index and the S&P 500 Index
on the Chicago Board Options Exchange, the Major Market Index and the Computer
Technology Index, Oil Index and Institutional Index on the American Stock
Exchange and the NYSE Index and NYSE Beta Index on the New York Stock Exchange,
The Financial News Composite Index on the Pacific Stock Exchange and the Value
Line Index, National O-T-C Index and Utilities Index on the Philadelphia Stock
Exchange, each of which and any similar index on which options are traded in the
future which include stocks that are not limited to any particular industry or
segment of the market is referred to as a "broadly based stock market index."
Options on stock indexes provide the Fund with a means of protecting the Fund
against the risk of market wide price movements. If the Adviser anticipates a
market decline, the Fund could purchase a stock index put option. If the
expected market decline materialized, the resulting decrease in the value of the
Fund's portfolio would be offset to the extent of the increase in the value of
the put option. If the Adviser anticipates a market rise, the Fund may purchase
a stock index call option to enable the Fund to participate in such rise until
completion of anticipated common stock purchases by the Fund. Purchases and
sales of stock index options also enable the Adviser to more speedily achieve
changes in the Fund's equity positions.
 
    The Fund will write put options on stock indexes only if such positions are
covered by cash, U.S. Government securities or other liquid portfolio securities
equal to the aggregate exercise price of the puts, which cover is held for the
Fund in a segregated account maintained for it by the Fund's Custodian. All call
options on stock indexes written by the Fund will be covered either by a
portfolio of stocks substantially replicating the movement of the index
underlying the call option or by holding a separate call option on the same
stock index with a strike price no higher than the strike price of the call
option sold by the Fund.
 
    RISKS OF OPTIONS ON INDEXES.  Because exercises of stock index options are
settled in cash, call writers such as the Fund cannot provide in advance for
their potential settlement obligations by acquiring and holding the underlying
securities. A call writer can offset some of the risk of its writing position by
holding a diversified portfolio of stocks similar to those on which the
underlying index is based. However, most investors cannot, as a practical
matter, acquire and hold a portfolio containing exactly the same stocks as the
underlying index, and, as a result, bear a risk that the value of the securities
held will vary from the value of the index. Even if an index call writer could
assemble a stock portfolio that exactly reproduced the composition of the
underlying index, the writer still would not be fully covered from a risk
standpoint because of the "timing risk" inherent in writing index options. When
an index option is exercised, the amount of cash that the holder is entitled to
receive is determined by the difference between the exercise price and the
closing index level on the date when the option is exercised. As with other
kinds of options, the writer will not learn that it has been assigned until the
next business day, at the earliest. The time lag between exercise and notice of
assignment poses no risk for the writer of a covered call on a specific
underlying security, such as a common stock, because there the writer's
obligation is to deliver the underlying security, not to pay its value as of a
fixed time in the past. So long as the writer already owns the underlying
security, it can satisfy its settlement obligations by simply delivering it, and
the risk that its value may have declined since the exercise date is borne by
the exercising holder. In contrast, even if the writer of an index call holds
stocks that exactly match the composition of the underlying index, it
 
                                       26
<PAGE>
will not be able to satisfy its assignment obligations by delivering those
stocks against payment of the exercise price. Instead, it will be required to
pay cash in an amount based on the closing index value on the exercise date; and
by the time it learns that it has been assigned, the index may have declined,
with a corresponding decrease in the value of its stock portfolio. This "timing
risk" is an inherent limitation on the ability of index call writers to cover
their risk exposure by holding stock positions.
 
    A holder of an index option who exercises it before the closing index value
for that day is available runs the risk that the level of the underlying index
may subsequently change. If such a change causes the exercised option to fall
out-of-the-money, the exercising holder will be required to pay the difference
between the closing index value and the exercise price of the option (times the
applicable multiplier) to the assigned writer.
 
    If dissemination of the current level of an underlying index is interrupted,
or if trading is interrupted in stocks accounting for a substantial portion of
the value of an index, the trading of options on that index will ordinarily be
halted. If the trading of options on an underlying index is halted, an exchange
may impose restrictions prohibiting the exercise of such options.
 
    FUTURES CONTRACTS.  The Fund may purchase and sell interest rate and stock
index futures contracts ("futures contracts") that are traded on U.S. commodity
exchanges on such underlying securities as U.S. Treasury bonds, notes and bills
("interest rate" futures) and such indexes as the S&P 500 Index, the Moody's
Investment-Grade Corporate Bond Index and the New York Stock Exchange Composite
Index ("index" futures).
 
    As a futures contract purchaser, the Fund incurs an obligation to take
delivery of a specified amount of the obligation underlying the contract at a
specified time in the future for a specified price. As a seller of a futures
contract, the Fund incurs an obligation to deliver the specified amount of the
underlying obligation at a specified time in return for an agreed upon price.
 
    The Fund will purchase or sell interest rate futures contracts and bond
index futures contracts for the purpose of hedging its fixed-income portfolio
securities (or anticipated portfolio securities) against changes in prevailing
interest rates. If the Adviser anticipates that interest rates may rise and,
concomitantly, the price of fixed-income securities fall, the Fund may sell an
interest rate futures contract or a bond index futures contract. If declining
interest rates are anticipated, the Fund may purchase an interest rate futures
contract to protect against a potential increase in the price of U.S. Government
securities the Fund intends to purchase. Subsequently, appropriate fixed-income
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.
 
    The Fund will purchase or sell stock index futures contracts for the purpose
of hedging its equity portfolio securities (or anticipated portfolio securities)
against changes in their prices. If the Adviser anticipates that the prices of
stock held by the Fund may fall, the Fund may sell a stock index futures
contract. Conversely, if the Adviser wishes to hedge against anticipated price
rises in those stocks which the Fund intends to purchase, the Fund may purchase
stock index futures contracts. In addition, interest rate and stock index
futures contracts will be bought or sold in order to close out a short or long
position in a corresponding futures contract.
 
    Although most interest rate futures contracts call for actual delivery or
acceptance of securities, the contracts usually are closed out before the
settlement date without the making or taking of delivery. Index futures
contracts provide for the delivery of an amount of cash equal to a specified
dollar amount times the difference between the stock index value at the open or
close of the last trading day of the contract and the futures contract price. A
futures contract sale is closed out by effecting a futures contract purchase for
the same aggregate amount of the specific type of equity security and the same
delivery date. If the sale price exceeds the offsetting purchase price, the
seller would be paid the difference and would realize a gain. If the offsetting
purchase price exceeds the sale price, the seller would pay the difference and
would realize a loss. Similarly, a futures contract purchase is closed out by
effecting a futures contract sale for the same aggregate amount of the specific
type of equity security and the same delivery date. If the offsetting sale 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 the Fund will be able to enter into a closing
transaction.
 
                                       27
<PAGE>
    INTEREST RATE FUTURES CONTRACTS.  When the Fund enters into an interest rate
futures contract, it is initially required to deposit with the Fund's Custodian,
in a segregated account in the name of the broker performing the transaction, an
"initial margin" of cash or U.S. Government securities or other liquid portfolio
securities equal to approximately 2% of the contract amount. 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.
 
    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 brokers' client but is, rather, a good faith deposit on the futures
contract which will be returned to the Fund upon the proper termination of the
futures contract. The margin deposits made are marked to market daily and the
Fund may be required to make subsequent deposits called "variation margin," with
the Fund's Custodian, in the account in the name of the broker, which are
reflective of price fluctuations in the futures contract. Currently, interest
rates futures contracts can be purchased on debt securities such as U.S.
Treasury Bills and Bonds, U.S. Treasury Notes with maturities between 6 1/2 and
10 years, GNMA Certificates and Bank Certificates of Deposit.
 
    INDEX FUTURES CONTRACTS.  The Fund may invest in index futures contracts. An
index futures contract sale creates an obligation by the Fund, as seller, to
deliver cash at a specified future time. An index futures contract purchase
would create an obligation by the Fund, as purchaser, to take delivery of cash
at a specified future time. Futures contracts on indexes do not require the
physical delivery of securities, but provide for a final cash settlement on the
expiration date which reflects accumulated profits and losses credited or
debited to each party's account.
 
    The Fund is required to maintain margin deposits with brokerage firms
through which it effects index futures contracts in a manner similar to that
described above for interest rate futures contracts. Currently, the initial
margin requirements range from 3% to 10% of the contract amount for index
futures. In addition, due to current industry practice, daily variations in
gains and losses on open contracts are required to be reflected in cash in the
form of variation margin payments. The Fund may be required to make additional
margin payments during the term of the contract.
 
    At any time prior to expiration of the futures contract, the 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
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 a gain.
 
    Currently, index futures contracts can be purchased or sold with respect to,
among others, the Standard & Poor's 500 Stock Price Index and the Standard &
Poor's 100 Stock Price Index on the Chicago Mercantile Exchange, the New York
Stock Exchange Composite Index on the New York Futures Exchange, the Major
Market Index on the American Stock Exchange, the Moody's Investment-Grade
Corporate Bond Index on the Chicago Board of Trade and the Value Line Stock
Index on the Kansas City Board of Trade.
 
    OPTIONS ON FUTURES CONTRACTS.  The Fund may purchase and write call and put
options on futures contracts 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), and the writer
the obligation, 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. Upon exercise of the
option, the delivery of the futures position by the writer of the option to the
holder of the option is accompanied by delivery of the accumulated balance in
the writer's futures margin account, which represents the amount by which the
market price of the futures contract at the time of exercise exceeds, in the
case of a call, or is less than, in the case of a put, the exercise price of the
option on the futures contract.
 
    The Fund 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, the Adviser 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
 
                                       28
<PAGE>
an interest rate futures contract, the underlying security of which correlates
with the portion of the portfolio the Adviser seeks to hedge. Any premiums
received in the writing of options on futures contracts may, of course, augment
the total return of the Fund and thereby provide a further hedge against losses
resulting from price declines in portions of the Fund's portfolio.
 
    The writer of an option on a futures contract is required to deposit initial
and variation margin pursuant to requirements similar to those applicable to
futures contracts. Premiums received from the writing of an option on a futures
contract are included in initial margin deposits.
 
    LIMITATIONS ON FUTURES CONTRACTS AND OPTIONS ON FUTURES.  The Fund may not
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 exceeds 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 calculating the 5%.
However, there is no overall limitation on the percentage of the Fund's assets
which may be subject to a hedge position. In addition, in accordance with the
regulations of the Commodity Futures Trading Commission ("CFTC") under which the
Fund is exempted from registration as a commodity pool operator, the Fund may
only enter into futures contracts and options on futures contracts transactions
for purposes of hedging a part or all of its portfolio. If the CFTC changes its
regulations so that the Fund would be permitted to write options on futures
contracts for purposes other than hedging the Fund's investments without CFTC
registration, the Fund may engage in such transactions for those purposes.
Except as described above, there are no other limitations on the use of futures
and options thereon by the Fund.
 
    RISKS OF TRANSACTIONS IN FUTURES CONTRACTS AND RELATED OPTIONS.  The
successful use of futures and related options depends on the ability of the
Adviser to accurately predict market, interest rate and currency movements. The
Fund may sell a futures contract to protect against the decline in the value of
securities held by the Fund. However, it is possible that the futures market may
advance and the value of securities held in the portfolio of the Fund may
decline. If this occurred, the Fund would lose money on the futures contract and
also experience a decline in value of its portfolio securities. However, while
this could occur for a very brief period or to a very small degree, over time
the value of a diversified portfolio will tend to move in the same direction as
the futures contracts.
 
    If the Fund purchases a futures contract to hedge against the increase in
value of securities it intends to buy, and the value of such securities
decreases, then the Fund may determine not to invest in the securities as
planned and will realize a loss on the futures contract that is not offset by a
reduction in the price of the securities.
 
    In order to assure that the Fund is entering into transactions in futures
contracts for hedging purposes as such is defined by the CFTC either: 1) a
substantial majority (i.e., approximately 75%) of all anticipatory hedge
transactions (transactions in which the Fund does not own at the time of the
transaction, but expects to acquire, the securities underlying the relevant
futures contract) involving the purchase of futures contracts will be completed
by the purchase of securities which are the subject of the hedge or 2) the
underlying value of all long positions in futures contracts will not exceed the
total value of a) all short-term debt obligations held by the Fund; b) cash held
by the Fund; c) cash proceeds due to the Fund on investments within thirty days;
d) the margin deposited on the contracts; and e) any unrealized appreciation in
the value of the contracts.
 
    In addition, if the Fund holds a long position in a futures contract or has
sold a put option on a futures contract, it will hold cash, U.S. Government
securities or other liquid portfolio securities obligations equal to the
purchase price of the contract or the exercise price of the put option (less the
amount of initial or variation margin on deposit) in a segregated account
maintained for the Fund by its Custodian. Alternatively, the Fund could cover
its long position by purchasing a put option on the same futures contract with
an exercise price as high or higher than the price of the contract held by the
Fund.
 
    If the Fund maintains a short position in a futures contract or has sold a
call option on a futures contract, it will cover this position by holding, in a
segregated account maintained at its Custodian, cash, U.S. Government
 
                                       29
<PAGE>
securities or other liquid portfolio securities equal in value (when added to
any initial or variation margin on deposit) to the market value of the
securities underlying the futures contract or the exercise price of the option.
Such a position may also be covered by owning the securities underlying the
futures contract (in the case of a stock index futures contract a portfolio of
securities substantially replicating the relevant index), or by holding a call
option permitting the Fund to purchase the same contract at a price no higher
than the price at which the short position was established.
 
    Exchanges may limit the amount by which the price of futures contracts 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, the Fund would
be required to make daily cash payments of variation margin on open futures
positions. In such situations, if the 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, the Fund may be required
to take 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 the
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 the 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 the Fund's transactions effected on foreign exchanges.
 
    The extent to which the Fund may enter into transactions involving options
and futures contracts may be limited by the Internal Revenue Code's requirements
for qualification as a regulated investment company and the Fund's intention to
qualify as such. See "Dividends, Distributions and Taxes" in the Prospectus and
the Statement of Additional Information.
 
    While the futures contracts and options transactions to be engaged in by the
Fund for the purpose of hedging the Fund's portfolio securities are not
speculative in nature, there are risks inherent in the use of such instruments.
One such risk which may arise in employing futures contracts to protect against
the price volatility of portfolio securities is that the prices of securities
and indexes subject to futures contracts (and thereby the futures contract
prices) may correlate imperfectly with the behavior of the cash prices of the
Fund's portfolio securities. Another such risk is that prices of interest rate
futures contracts may not move in tandem with the changes in prevailing interest
rates against which the Fund seeks a hedge. A correlation may also be distorted
(a) temporarily, by short-term traders seeking to profit from the difference
between a contract or security price objective and their cost of borrowed funds;
(b) by investors in futures contracts electing to close out their contracts
through offsetting transactions rather than meet margin deposit requirements;
(c) by investors in futures contracts opting to make or take delivery of
underlying securities rather than engage in closing transactions, thereby
reducing liquidity of the futures market; and (d) temporarily, by speculators
who view the deposit requirements in the futures markets as less onerous than
margin requirements in the cash market. Due to the possibility of price
distortion in the futures market and because of the imperfect correlation
between movements in the prices of securities and movements in the prices of
futures contracts, a correct forecast of interest rate trends may still not
result in a successful hedging transaction.
 
    There is no assurance that a liquid secondary market will exist for futures
contracts and related options in which the 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, the 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 the 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 the Fund to make or take delivery of the
underlying securities at a time when it may be disadvantageous to do so.
 
                                       30
<PAGE>
    Compared to the purchase or sale of futures contracts, the purchase of call
or put options on futures contracts involves less potential risk to the Fund
because the maximum amount at risk is the premium 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 the 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.
 
    The Adviser has substantial experience in the use of the investment
techniques described above under the heading "Options and Futures Transactions,"
which techniques require skills different from those needed to select the
portfolio securities underlying various options and futures contracts.
 
LENDING OF PORTFOLIO SECURITIES
 
    Consistent with applicable regulatory requirements, the Fund may lend its
portfolio securities to brokers, dealers and other financial institutions,
provided that such loans are callable at any time by the Fund (subject to notice
provisions described below), and are at all times secured by cash or money
market instruments, which are maintained in a segregated account pursuant to
applicable regulations and that are equal to at least the market value,
determined daily, of the loaned securities. The advantage of such loans is that
the Fund continues 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. The Fund will not lend its portfolio
securities if such loans are not permitted by the laws or regulations of any
state in which its shares are qualified for sale and 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 the Fund on two business days' 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 extensions of credit, there are risks of delay in recovery and in
some cases even loss of rights in the collateral should the borrower of the
securities fail financially. However, these loans of portfolio securities will
only be made to firms deemed by the Fund's management to be creditworthy and
when the income which can be earned from such loans justifies the attendant
risks. Upon termination of the loan, the borrower is required to return the
securities to the Fund. Any gain or loss in the market price during the loan
period would inure to the Fund. The creditworthiness of firms to which the Fund
lends its portfolio securities will be monitored on an ongoing basis by the
Adviser pursuant to procedures adopted and reviewed, on an ongoing basis, by the
Board of Trustees of the Fund.
 
    When voting or consent rights which accompany loaned securities pass to the
borrower, the Fund will follow the policy of calling the loaned securities, to
be delivered within one day after notice, to permit the exercise of such rights
if the matters involved would have a material effect on the Fund's investment in
such loaned securities. The Fund will pay reasonable finder's, administrative
and custodial fees in connection with a loan of its securities.
 
PORTFOLIO TURNOVER
 
   
    It is anticipated that the Fund's portfolio turnover rate generally will not
exceed 150%. A 150% turnover rate would occur, for example, if 150% of the
securities held in the Fund's portfolio (excluding all securities whose
maturities at acquisition were one year or less) were sold and replaced within
one year. For the fiscal years ended September 30, 1996 and September 30, 1997,
the Fund's portfolio turnover rate was approximately 117% and 80%, respectively.
    
 
INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------
 
    In addition to the investment restrictions enumerated in the Prospectus, the
investment restrictions listed below have been adopted by the Fund as
fundamental policies, except as otherwise indicated. Under the Act, a
fundamental policy may not be changed without the vote of a majority of the
outstanding voting securities of the Fund, as defined in the Act. Such a
majority is defined as the lesser of (a) 67% or more of the shares present at a
meeting of shareholders, if the holders of 50% of the outstanding shares of the
Fund are present or represented by proxy or (b) more than 50% of the outstanding
shares of the Fund.
 
                                       31
<PAGE>
    The Fund may not:
 
       1.  Purchase or sell real estate or interests therein (including limited
           partnership interests), although the Fund may purchase securities of
    issuers which engage in real estate operations and securities secured by
    real estate or interests therein.
 
       2.  Purchase oil, gas or other mineral leases, rights or royalty
           contracts or exploration or development programs, except that the
    Fund may invest in the securities of companies which operate, invest in, or
    sponsor such programs.
 
       3.  Borrow money, except that the Fund (i) may borrow from a bank for
           temporary or emergency purposes in amounts not exceeding 5% (taken at
    the lower of cost or current value) of its total assets (not including the
    amount borrowed), and (ii) may engage in reverse repurchase agreements and
    dollar rolls.
 
       4.  Pledge its assets or assign or otherwise encumber them except to
           secure borrowings effected within the limitations set forth in
    restriction (3). For the purpose of this restriction, collateral
    arrangements with respect to initial or variation margin for futures are not
    deemed to be pledges of assets.
 
       5.  Issue senior securities as defined in the Act except insofar as the
           Fund may be deemed to have issued a senior security by reason of (a)
    entering into any repurchase agreement; (b) purchasing any securities on a
    when-issued or delayed delivery basis; (c) purchasing or selling any
    financial futures contracts or options thereon; (d) borrowing money in
    accordance with restrictions described above; or (e) lending portfolio
    securities.
 
       6.  Make loans of money or securities, except: (a) by the purchase of
           portfolio securities in which the Fund may invest consistent with its
    investment objective and policies; (b) by investment in repurchase
    agreements; or (c) by lending its portfolio securities.
 
       7.  Make short sales of securities.
 
       8.  Purchase securities on margin, except for such short-term loans as
           are necessary for the clearance of portfolio securities. The deposit
    or payment by the Fund of initial or variation margin in connection with
    futures contracts is not considered the purchase of a security on margin.
 
       9.  Purchase or sell commodities or commodities contracts except that the
           Fund may purchase or sell futures contracts or options on futures.
 
       10. Engage in the underwriting of securities, except insofar as the Fund
           may be deemed an underwriter under the Securities Act of 1933 in
    disposing of a portfolio security. (The Fund may invest in restricted
    securities subject to the non-fundamental limitations contained in the
    Prospectus.)
 
       11. Invest for the purpose of exercising control or management of any
           other issuer.
 
    In addition, as a nonfundamental policy, the Fund may not purchase
securities of other investment companies, except in connection with a merger,
consolidation, reorganization or acquisition of assets or by purchase in the
open market of securities of closed-end investment companies where no
underwriter's or dealer's commission or profit, other than customary broker's
commissions, is involved and only if immediately thereafter not more than (a) 5%
of the Fund's total assets, taken at market value, would be invested in any one
such company, (b) 10% of the Fund's total assets, taken at market value, would
be invested in such securities and (c) 3% of any one such company's voting
securities would be owned by the Fund.
 
    As a non-fundamental policy, the Fund may not invest in other investment
companies in reliance on Sections 12(d)(1)(F), 12(d)(1)(G) or 12(d)(1)(J) of the
Act.
 
    If (except with respect to Restriction 3) a percentage restriction is
adhered to at the time of investment, a later increase or decrease in percentage
resulting from a change in values of portfolio securities or amount of total or
net assets will not be considered a violation of any of the foregoing
restrictions.

PORTFOLIO TRANSACTIONS AND BROKERAGE
- --------------------------------------------------------------------------------
 
   
    Subject to the general supervision of the Trustees, the Adviser is
responsible for decisions to buy and sell securities for the Fund, the selection
of brokers and dealers to effect the transactions, and the negotiation of
brokerage commissions, if any. Purchases and sales of securities on a stock
exchange are effected through brokers who charge a commission for their
services. In the over-the-counter market, securities are generally traded on a
"net" basis with dealers acting as principal for their own accounts without a
stated commission, although the price of the security usually includes a profit
to the dealer. In addition, securities may be purchased at times in underwritten
offerings where the price includes a fixed amount of compensation, generally
referred to as the underwriter's concession or discount. Futures transactions
will usually be effected through a broker and a commission will be charged. On
occasion, the Fund may also purchase certain money market instruments directly
from an issuer, in which case no commissions or discounts are paid. During the
fiscal years ended September 30, 1995, 1996 and 1997 the Fund paid $223,076,
$130,941 and $96,388, respectively, in brokerage commissions.
    
 
    The Adviser currently serves as investment adviser to a number of clients,
including other investment companies, and may in the future act as investment
adviser to others. It is the practice of the Adviser to cause purchase and sale
transactions to be allocated among the Fund and others whose assets it manages
in such manner as it deems equitable. In making such allocations among the Fund
and other client accounts, the main factors considered are the respective
investment objectives, the relative size of portfolio holdings of the same or
comparable securities, the availability of cash for investment, the size of
investment commitments generally held and the opinions of the persons
responsible for managing the portfolios of the Fund and other client accounts.
 
    The policy of the Fund regarding purchases and sales of securities for its
portfolio is that primary consideration will be given to obtaining the most
favorable prices and efficient executions of transactions. Consistent with this
policy, when securities transactions are effected on a stock exchange, the
Fund's policy is to pay commissions which are considered fair and reasonable
without necessarily determining that the lowest possible commissions are paid in
all circumstances. The Fund believes that a requirement always to seek the
lowest possible commission cost could impede effective portfolio management and
preclude the Fund and the Adviser from obtaining a high quality of brokerage and
research services. In seeking to determine the reasonableness of brokerage
commissions paid in any transaction, the Adviser relies upon its experience and
knowledge regarding commissions generally charged by various brokers and on its
judgment in evaluating the brokerage and research services received from the
broker effecting the transaction. Such determinations are necessarily subjective
and imprecise, as in most cases an exact dollar value for those services is not
ascertainable.
 
   
    In seeking to implement the Fund's policies, the Adviser effects
transactions with those brokers and dealers who the Adviser believes provide the
most favorable prices and are capable of providing efficient executions. If the
Adviser believes such prices and executions are obtainable from more than one
broker or dealer, it may give consideration to placing portfolio transactions
with those brokers and dealers who also furnish research and other services to
the Fund or the Adviser. Such services may include, but are not limited to, any
one or more of the following: 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, availability of securities, availability of
buyers, and availability of sellers. In addition, they include recommendations
as to purchase and sale of individual securities and timing of such
transactions. The Fund will not purchase at a higher price or sell at a lower
price in connection with transactions affected with a dealer, acting as
principal, who furnishes research services to the Fund than would be the case if
no weight were given by the Fund to the dealer's furnishing of such services.
During the fiscal year ended September 30, 1997, the Fund directed the payment
of $72,639 in brokerage commissions in connection with transactions in the
aggregate amount of $58,756,856 to brokers because of research services
provided.
    
 
    The information and services received by the Adviser from brokers and
dealers may be of benefit to the Adviser in the management of accounts of some
of its other clients and may not in all cases benefit the Fund
 
                                       33
<PAGE>
directly. While the receipt of such information and services is useful in
varying degrees and would generally reduce the amount of research or services
otherwise performed by the Adviser and thereby reduce its expenses, it is of
indeterminable value and the advisory fee paid to the Adviser is not reduced by
any amount that may be attributable to the value of such services.
 
   
    Consistent with the policy described above, brokerage transactions in
securities listed on exchanges or admitted to unlisted trading privileges may be
effected through DWR and other affiliated brokers and dealers. In order for an
affiliated broker or dealer to effect any portfolio transactions for the Fund,
the commissions, fees or other remuneration received by the affiliated broker or
dealer must be reasonable and fair compared to the commissions, fees or other
remuneration paid to other brokers in connection with comparable transactions
involving similar securities being purchased or sold on an exchange during a
comparable period of time. This standard would allow an affiliated broker or
dealer to receive no more than the remuneration which would be expected to be
received by an unaffiliated broker in a commensurate arm's-length transaction.
Furthermore, the Board of Trustees of the Fund, including a majority of the
Trustees who are not "interested" persons of the Fund, as defined in the Act,
have adopted procedures which are reasonably designed to provide that any
commissions, fees or other remuneration paid to the affiliated broker or dealer
are consistent with the foregoing standard. During the fiscal years ended
September 30, 1995, 1996 and 1997, the Fund paid a total of $49,753, $9,886 and
$10,895, respectively, in commissions to DWR. During the fiscal year ended
September 30, 1997, the brokerage commissions paid to DWR represented
approximately 11.30% of the total brokerage commissions paid by the Fund during
the period and were paid on account of transactions having an aggregate dollar
value equal to approximately 17.38% of the aggregate dollar value of all
portfolio transactions of the Fund during the period for which commissions were
paid.
    
 
   
    During the period June 1 through September 30, 1997, the Fund paid a total
of $1,140 in brokerage commissions to Morgan Stanley & Co., Inc., which
broker-dealer became an affiliate of the Distributor on May 31, 1997 upon
consummation of the merger of Dean Witter, Discover & Co. with Morgan Stanley
Group Inc. The brokerage commissions paid to Morgan Stanley & Co., Inc.
represented approximately 1.18% of the total brokerage commissions paid by the
Fund for this period and were paid on account of transactions having an
aggregate dollar value equal to approximately 1.32% of the aggregate dollar
value of all portfolio transactions of the Fund during the period for which
commissions were paid.
    
 
   
    During the fiscal year ended September 30, 1997, the Fund purchased a
collateralized mortgage obligation, 6.50%, 6/28/24 issued by Bear Stearns
Mortgage Securities Inc. and common stock issued by Merrill Lynch & Co. At
September 30, 1997, the Fund held the aforementioned securities with market
values of $582,885 and $1,787,919, respectively. These issuers were among the
ten brokers or the ten dealers which executed transactions for or with the Fund
in the largest dollar amounts during the fiscal year ended September 30, 1997.
    
 
THE DISTRIBUTOR
- --------------------------------------------------------------------------------
 
    As discussed in the Prospectus, shares of the Fund are distributed by Dean
Witter Distributors Inc. (the "Distributor"). The Distributor has entered into a
selected dealer agreement with DWR, which through its own sales organization
sells shares of the Fund, and may enter into selected broker-dealer agreements
with others. The Distributor, a Delaware corporation, is a wholly-owned
subsidiary of MSDWD. As part of an internal reorganization that took place in
December, 1992, the Distributor assumed the investment company share
distribution activities previously performed by DWR. The Trustees of the Fund,
including a majority of the Independent Trustees, approved, at their meeting on
June 30, 1997, the current Distribution Agreement appointing the Distributor
exclusive distributor of the Fund's shares and providing for the Distributor to
bear distribution expenses not borne by the Fund. By its terms, the Distribution
Agreement has an initial term ending April 30, 1998, and provides that it will
remain in effect from year to year thereafter if approved by the Board.
 
    The Distributor bears all expenses it may incur in providing services under
the Distribution Agreement. Such expenses include the payment of commissions for
sales of the Fund's shares and incentive compensation to account executives. The
Distributor also pays certain expenses in connection with the distribution of
the
 
                                       34
<PAGE>
Fund's shares, including the costs of preparing, printing and distributing
advertising or promotional materials, and the costs of printing and distributing
prospectuses and supplements thereto used in connection with the offering and
sale of the Fund's shares. The Fund bears the costs of initial typesetting,
printing and distribution of prospectuses and supplements thereto to
shareholders. The Fund also bears the costs of registering the Fund and its
shares under federal securities laws and pays filing fees in accordance with
state securities laws. The Fund and Distributor have agreed to indemnify each
other against certain liabilities, including liabilities under the Securities
Act of of 1933, as amended. Under the Distribution Agreement, the Distributor
uses its best efforts in rendering services to the Fund, but in the absence of
willful misfeasance, bad faith, gross negligence or reckless disregard of its
obligations, the Distributor is not liable to the Fund or any of its
shareholders for any error of judgment or mistake of law or for any act or
omission or for any losses sustained by the Fund or its shareholders.
 
PLAN OF DISTRIBUTION
 
   
    PLAN OF DISTRIBUTION.  The Fund has adopted a Plan of Distribution pursuant
to Rule 12b-1 under the Act (the "Plan") pursuant to which each Class, other
than Class D, pays the Distributor compensation accrued daily and payable
monthly at the following annual rates: 0.25%, 1.0% and 1.0% of the average daily
net assets of Class A, Class B and Class C, respectively. The Distributor also
receives the proceeds of front-end sales charges and of contingent deferred
sales charges imposed on certain redemptions of shares, which are separate and
apart from payments made pursuant to the Plan (see "Purchase of Fund Shares" in
the Prospectus). The Distributor has informed the Fund that it and/or DWR
received (a) approximately $0, $1,110 and $216 in contingent deferred sales
charges from Class A, Class B and Class C, respectively, for the fiscal year
ended September 30, 1997, and (b) approximately $524 in front-end sales charges
from Class A for the fiscal year ended September 30, 1997, none of which was
retained by the Distributor.
    
 
    The Distributor has informed the Fund that the entire fee payable by Class A
and a portion of the fees payable by each of Class B and Class C each year under
the Plan equal to 0.25% of such Class's average daily net assets are currently
each characterized as a "service fee" under the Rules of the Association of the
National Association of Securities Dealers (of which the Distributor is a
member). The service fee is a payment made for personal service and/or the
maintenance of shareholder accounts. The remaining portion of the Plan fees
payable by a Class, if any, is characterized an "asset-based sales charge" as
such is defined by the aforementioned Rules of the Association.
 
    The Plan was adopted by a majority vote of the Board of Trustees, including
all of the Trustees of the Fund who are not "interested persons" of the Fund (as
defined in the Act) and who have no direct or indirect financial interest in the
operation of the Plan (the "Independent 12b-1 Trustees"), cast in person at a
meeting called for the purpose of voting on the Plan, on July 21, 1993, and by
InterCapital as the then sole shareholder of the Fund on July 22, 1993.
 
    At their meeting held on October 26, 1995, the Trustees of the Fund,
including all the Independent 12b-1 Trustees, approved an amendment to the Plan
to permit payments to be made under the Plan with respect to certain
distribution expenses incurred in connection with the distribution of shares,
including personal services to shareholders with respect to holdings of such
shares, of an investment company whose assets are acquired by the Fund in a
tax-free reorganization. At their meeting held on June 30, 1997, the Trustees,
including a majority of the Independent 12b-1 Trustees, approved amendments to
the Plan to reflect the multiple-class structure for the Fund, which took effect
on July 28, 1997.
 
   
    Under the Plan and as required by Rule 12b-1, the Trustees receive and
review promptly after the end of each fiscal quarter a written report provided
by the Distributor of the amounts expended under the Plan and the purpose for
which such expenditures were made. In the Trustees' quarterly reviews of the
Plan, they will consider its continued appropriateness and the level of
compensation provided therein. Class C shares of the Fund accrued amounts
payable to the Distributor under the Plan, during the fiscal year ended
September 30, 1997, of $908,897. This amount is equal to payments required to be
paid monthly by the Fund which were computed at the annual rate of 0.99% of the
average daily net assets of Class C. The 12b-1 fee is treated by the Fund as an
expense in the year it is accrued. For the fiscal period July 28, 1997 through
September 30, 1997,
    
 
                                       35
<PAGE>
   
Class A and Class B shares of the Fund accrued payments under the Plan amounting
to $13 and $9,461, respectively, which amounts are equal to 0.25% and 1.00% of
the average daily net assets of Class A and Class B, respectively, for such
period.
    
 
    The Plan was adopted in order to permit the implementation of the Fund's
method of distribution. Under this distribution method the Fund offers four
Classes of shares, each with a distribution arrangement as set forth in the
Prospectus.
 
   
    With respect to Class A shares, DWR compensates its account executives by
paying them, from proceeds of the front-end sales charge, commissions for the
sale of Class A shares, currently a gross sales credit of up to 5.0% of the
amount sold (except as provided in the following sentence) and an annual
residual commission, currently a residual of up to 0.25% of the current value of
the respective accounts for which they are the account executives or dealers of
record in all cases. On orders of $1 million or more (for which no sales charge
was paid) or net asset value purchases by 401(k) plans or other
employer-sponsored plans qualified under Section 401(a) of the Internal Revenue
Code for which Dean Witter Trust FSB ("DWT") serves as Trustee or the 401(k)
Support Services Group of DWR serves as recordkeeper, InterCapital compensates
DWR's account executives by paying them, from its own funds, a gross sales
credit of 1.0% of the amount sold.
    
 
   
    With respect to Class B shares, DWR compensates its account executives by
paying them, from its own funds, commissions for the sale of Class B shares,
currently a gross sales credit of up to 5.0% of the amount sold (except as
provided in the following sentence) and an annual residual commission, currently
a residual of up to 0.25% of the current value of the respective accounts for
which they are the account executives of record in all cases. In the case of
retirement plans qualified under Section 401(k) of the Internal Revenue Code and
other employer-sponsored plans qualified under Section 401(a) of the Internal
Revenue Code for which DWT serves as Trustee or the 401(k) Support Services
Group of DWR serves as recordkeeper, and which plans are opened on or after July
28, 1997, DWR compensates its account executives by paying them, from its own
funds, a gross sales credit of 3.0% of the amount sold.
    
 
    With respect to Class C shares, DWR compensates its account executives by
paying them, from its own funds, commissions for the sale of Class C shares,
currently a gross sales credit of up to 1.0% of the amount sold and an annual
residual commission, currently a residual of up to 1.0% of the current value of
the respective accounts for which they are the account executives of record.
 
    With respect to Class D shares other than shares held by participants in the
InterCapital mutual fund asset allocation program, InterCapital compensates
DWR's account executives by paying them, from its own funds, commissions for the
sale of Class D shares, currently a gross sales credit of up to 1.0% of the
amount sold. There is a chargeback of 100% of the amount paid if the Class D
shares are redeemed in the first year and a chargeback of 50% of the amount paid
if the Class D shares are redeemed in the second year after purchase.
InterCapital also compensates DWR's account executives by paying them, from its
own funds, an annual residual commission, currently a residual of up to 0.10% of
the current value of the respective accounts for which they are the account
executives of record (not including accounts of participants in the InterCapital
mutual fund asset allocation program).
 
    The gross sales credit is a charge which reflects commissions paid by DWR to
its account executives and DWR's Fund-associated distribution-related expenses,
including sales compensation, and overhead and other branch office
distribution-related expenses including (a) the expenses of operating DWR's
branch offices in connection with the sale of Fund shares, including lease
costs, the salaries and employee benefits of operations and sales support
personnel, utility costs, communications costs and the costs of stationery and
supplies, (b) the costs of client sales seminars, (c) travel expenses of mutual
fund sales coordinators to promote the sale of Fund shares and (d) other
expenses relating to branch promotion of Fund sales. The distribution fee that
the Distributor receives from the Fund under the Plan, in effect, offsets
distribution expenses incurred under the Plan on behalf of the Fund and, in the
case of Class B shares, opportunity costs, such as the gross sales credit and an
assumed interest charge thereon ("carrying charge"). In the Distributor's
reporting of the distribution expenses to the Fund, in the case of Class B
shares, such assumed interest (computed at the "broker's call rate") has been
calculated on the gross credit as it is reduced by amounts received by the
Distributor under the Plan and any contingent deferred sales charges received by
the Distributor upon redemption of shares of the Fund.
 
                                       36
<PAGE>
No other interest charge is included as a distribution expense in the
Distributor's calculation of its distribution costs for this purpose. The
broker's call rate is the interest rate charged to securities brokers on loans
secured by exchange-listed securities.
 
   
    Each Class paid 100% of the amounts accrued under the Plan with respect to
the Class for the fiscal year ended September 30, 1997 to the Distributor. The
Distributor estimates it has spent, pursuant to the Plan, $8,052 on behalf of
Class B since the inception of the Plan. It is estimated that this amount was
spent in approximately the following ways: (i) 1.22% ($98)--advertising and
promotional expenses; (ii) 0% ($0)-- printing of prospectuses for distribution
to other than current shareholders; and (iii) 98.78% ($7,954)--other expenses,
including the gross sales credit and the carrying charges of which 0% ($0)
represents carrying charges, 40.39% ($3,213) represents commission credits to
DWR branch offices for payments of commissions to account executives and 59.61%
($4,741) represents overhead and other branch office distribution-related
expenses. The term "overhead and other branch office distribution-related
expenses" represents (a) the expenses of operating DWR's branch offices in
connection with the sale of the Fund shares, including lease costs, the salaries
and employee benefits of operations and sales support personnel, utility costs,
communications costs and the costs of stationery and supplies; (b) the costs of
client sales seminars; (c) travel expenses of Mutual Fund sales coordinators to
promote the sale of Fund shares; and (d) other expenses relating to branch
promotion of Fund share sales. The amounts accrued by Class A for distribution
during the fiscal period July 28, 1997 through September 30, 1997 were for
expenses which relate to compensation of sales personnel and associated overhead
expenses.
    
 
   
    The Fund is authorized to reimburse expenses incurred or to be incurred in
promoting the distribution of the Fund's Class A and Class C shares and in
servicing shareholder accounts. Reimbursement will be made through payments at
the end of each month. The amount of each monthly payment may in no event exceed
an amount equal to a payment at the annual rate of 0.25%, in the case of Class
A, and 1.0%, in the case of Class C, of the average net assets of the respective
Class during the month. No interest or other financing charges, if any, incurred
on any distribution expenses on behalf of Class A and Class C will be
reimbursable under the Plan. With respect to Class A, in the case of all
expenses other than expenses representing the service fee, and, with respect to
Class C, in the case of all expenses other than expenses representing a gross
sales credit or a residual to account executives, such amounts shall be
determined at the beginning of each calendar quarter by the Trustees, including,
a majority of the Independent 12b-1 Trustees. Expenses representing the service
fee (for Class A) or a gross sales credit or a residual to account executives
(for Class C) may be reimbursed without prior determination. In the event that
the Distributor proposes that monies shall be reimbursed for other than such
expenses, then in making quarterly determinations of the amounts that may be
reimbursed by the Fund, the Distributor will provide and the Trustees will
review a quarterly budget of projected distribution expenses to be incurred on
behalf of the Fund, together with a report explaining the purposes and
anticipated benefits of incurring such expenses. The Trustees will determine
which particular expenses, and the portions thereof, that may be borne by the
Fund, and in making such a determination shall consider the scope of the
Distributor's commitment to promoting the distribution of the Fund's Class A and
Class C shares.
    
 
   
    In the case of Class B shares, at any given time, the expenses of
distributing shares of the Fund may be more or less than the total of (i) the
payments made by the Fund pursuant to the Plan and (ii) the proceeds of
contingent deferred sales charges paid by investors upon redemption of shares.
Because there is no requirement under the Plan that the Distributor be
reimbursed for all distribution expenses with respect to Class B shares or any
requirement that the Plan be continued from year to year, this excess amount
does not constitute a liability of the Fund. Although there is no legal
obligation for the Fund to pay expenses incurred in excess of payments made to
the Distributor under the Plan and the proceeds of contingent deferred sales
charges paid by investors upon redemption of shares, if for any reason the Plan
is terminated, the Trustees will consider at that time the manner in which to
treat such expenses. Any cumulative expenses incurred, but not yet recovered
through distribution fees or contingent deferred sales charges, may or may not
be recovered through future distribution fees or contingent deferred sales
charges.
    
 
    No interested person of the Fund nor any Trustee of the Fund who is not an
interested person of the Fund, as defined in the Act, has any direct or indirect
financial interest in the operation of the Plan except to the extent that DWR,
InterCapital, the Distributor or the Manager, or certain of their employees, may
be deemed to have
 
                                       37
<PAGE>
such an interest as a result of benefits derived from the successful operation
of the Plan or as a result of receiving a portion of the amounts expended
thereunder by the Fund.
 
    Under its terms, the Plan had an initial term ending April 30, 1994, and
provides that it will continue from year to year thereafter, provided such
continuance is approved annually by a vote of the Trustees in the manner
described above. Prior to the Board's approval of amendments to the Plan to
reflect the multiple class structure for the Fund, the most recent continuance
of the Plan for one year, until April 30, 1998, was approved by the Board of
Trustees of the Fund, including a majority of the Independent 12b-1 Trustees, at
a Board meeting held on April 24, 1997. Prior to approving the continuation of
the Plan, the Board requested and received from the Distributor and reviewed all
the information which it deemed necessary to arrive at an informed
determination. In making their determination to continue the Plan, the Trustees
considered: (1) the Fund's experience under the Plan and whether such experience
indicates that the Plan is operating as anticipated; (2) the benefits the Fund
had obtained, was obtaining and would be likely to obtain under the Plan; and
(3) what services had been provided and were continuing to be provided under the
Plan by the Distributor, DWR and other selected broker-dealers to the Fund and
its shareholders. Based upon their review, the Trustees of the Fund, including
each of the Independent 12b-1 Trustees, determined that continuation of the Plan
would be in the best interest of the Fund and would have a reasonable likelihood
of continuing to benefit the Fund and its shareholders. This determination was
based upon the conclusion of the Trustees that the Plan provides an effective
means of stimulating sales of shares of the Fund and of reducing or avoiding net
redemptions and the potentially adverse effects that may occur therefrom. In the
Trustees' quarterly review of the Plan, they will consider its continued
appropriateness and the level of compensation provided therein.
 
   
    The Plan may not be amended to increase materially the amount to be spent
for the services described therein without approval of the shareholders of the
affected Class or Classes of the Fund, and all material amendments of the Plan
must also be approved by the Trustees in the manner described above. The Plan
may be terminated at any time, without payment of any penalty, by vote of a
majority of the Independent 12b-1 Trustees or by a vote of a majority of the
outstanding voting securities of the Fund (as defined in the Act) on not more
than thirty days' written notice to any other party to the Plan. So long as the
Plan is in effect, the election and nomination of Independent 12b-1 Trustees
shall be committed to the discretion of the Independent 12b-1 Trustees.
    
 
DETERMINATION OF NET ASSET VALUE
- --------------------------------------------------------------------------------
 
    As stated in the Prospectus, short-term securities with remaining maturities
of sixty days or less at the time of purchase are valued at amortized cost,
unless the Trustees determine such does not reflect the securities' market
value, in which case these securities will be valued at their fair value as
determined by the Trustees. Other short-term debt securities will be valued on a
mark-to-market basis until such time as they reach a remaining maturity of sixty
days, whereupon they will be valued at amortized cost using their value on the
61st day unless the Trustees determine such does not reflect the securities'
market value, in which case these securities will be valued at their fair value
as determined by the Trustees. Listed options on debt securities are valued at
the latest sale price on the exchange on which they are listed unless no sales
of such options have taken place that day, in which case they will be valued at
the mean between their latest bid and asked prices. Unlisted options on debt
securities and all options on equity securities are valued at the mean between
their latest bid and asked prices. Futures are valued at the latest sale price
on the commodities exchange on which they trade unless the Trustees determine
that such price does not reflect their market value, in which case they will be
valued at their fair value as determined by the Trustees. All other securities
and other assets are valued at their fair value as determined in good faith
under procedures established by and under the supervision of the Trustees.
 
    The net asset value per share for each Class of shares of the Fund is
determined once daily at 4:00 p.m., New York time (or, on days when the New York
Stock Exchange closes prior to 4:00 p.m., at such earlier time), on each day
that the New York Stock Exchange is open. The New York Stock Exchange currently
observes the following holidays: New Year's Day, Reverend Dr. Martin Luther
King, Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence Day,
Labor Day, Thanksgiving Day and Christmas Day.
 
                                       38

PURCHASE OF FUND SHARES
- --------------------------------------------------------------------------------
 
    As discussed in the Prospectus, the Fund offers four Classes of shares as
follows:
 
INITIAL SALES CHARGE ALTERNATIVE--CLASS A SHARES
 
    Class A shares are sold to investors with an initial sales charge that
declines to zero for larger purchases; however, Class A shares sold without an
initial sales charge are subject to a contingent deferred sales charge ("CDSC")
of 1.0% if redeemed within one year of purchase, except in the circumstances
discussed in the Prospectus.
 
    RIGHT OF ACCUMULATION.  As discussed in the Prospectus, investors may
combine the current value of shares purchased in separate transactions for
purposes of benefitting from the reduced sales charges available for purchases
of shares of the Fund totalling at least $25,000 in net asset value. For
example, if any person or entity who qualifies for this privilege holds Class A
shares of the Fund and/or other TCW/DW Funds which are multiple class funds
("TCW/DW Multi-Class Funds") purchased at a price including a front-end sales
charge having a current value of $5,000, and purchases $20,000 of additional
shares of the Fund, the sales charge applicable to the $20,000 purchase would be
4.75% of the offering price.
 
   
    The Distributor must be notified by the selected broker-dealer or the
shareholder at the time a purchase order is placed that the purchase qualifies
for the reduced charge under the Right of Accumulation. Similar notification
must be made in writing by the selected broker-dealer or shareholder when such
an order is placed by mail. The reduced sales charge will not be granted if: (a)
such notification is not furnished at the time of the order; or (b) a review of
the records of the Distributor or Dean Witter Trust FSB (the "Transfer Agent")
fails to confirm the investor's represented holdings.
    
 
    LETTER OF INTENT.  As discussed in the Prospectus, reduced sales charges are
available to investors who enter into a written Letter of Intent providing for
the purchase, within a thirteen-month period, of Class A shares of the Fund from
the Distributor or from a single Selected Broker-Dealer.
 
    A Letter of Intent permits an investor to establish a total investment goal
to be achieved by any number of purchases over a thirteen-month period. Each
purchase of Class A shares made during the period will receive the reduced sales
commission applicable to the amount represented by the goal, as if it were a
single purchase. A number of shares equal in value to 5% of the dollar amount of
the Letter of Intent will be held in escrow by the Transfer Agent, in the name
of the shareholder. The initial purchase under a Letter of Intent must be equal
to at least 5% of the stated investment goal.
 
    The Letter of Intent does not obligate the investor to purchase, nor the
Fund to sell, the indicated amount. In the event the Letter of Intent goal is
not achieved within the thirteen-month period, the investor is required to pay
the difference between the sales charge otherwise applicable to the purchases
made during this period and sales charges actually paid. Such payment may be
made directly to the Distributor or, if not paid, the Distributor is authorized
by the shareholder to liquidate a sufficient number of his or her escrowed
shares to obtain such difference.
 
    If the goal is exceeded and purchases pass the next sales charge level, the
sales charge on the entire amount of the purchase that results in passing that
level and on subsequent purchases will be subject to further reduced sales
charges in the same manner as set forth above under "Right of Accumulation," but
there will be no retroactive reduction of sales charges on previous purchases.
For the purpose of determining whether the investor is entitled to a further
reduced sales charge applicable to purchases at or above a sales charge level
which exceeds the stated goal of a Letter of Intent, the cumulative current net
asset value of any shares owned by the investor in any other TCW/DW Multi-Class
Funds held by the shareholder which were previously purchased at a price
including a front-end sales charge (including shares of the Fund, other TCW/DW
Multi-Class Funds or "Exchange Funds" (see "Shareholder Services--Exchange
Privilege") acquired in exchange for those shares, and including in each case
shares acquired through reinvestment of dividends and distributions) will be
added to the cost or net asset value of shares of the Fund owned by the
investor. However, shares of "Exchange Funds" and the purchase of shares of
other TCW/DW Funds will not be included in determining whether the stated goal
of a Letter of Intent has been reached.
 
                                       39
<PAGE>
    At any time while a Letter of Intent is in effect, a shareholder may, by
written notice to the Distributor, increase the amount of the stated goal. In
that event, only shares purchased during the previous 90-day period and still
owned by the shareholder will be included in the new sales charge reduction. The
5% escrow and minimum purchase requirements will be applicable to the new stated
goal. Investors electing to purchase shares of the Fund pursuant to a Letter of
Intent should carefully read such Letter of Intent.
 
CONTINGENT DEFERRED SALES CHARGE ALTERNATIVE--CLASS B SHARES
 
    Class B shares are sold without an initial sales charge but are subject to a
CDSC payable upon most redemptions within six years after purchase. As stated in
the Prospectus, a CDSC will be imposed on any redemption by an investor if after
such redemption the current value of the investor's Class B shares of the Fund
is less than the dollar amount of all payments by the shareholder for the
purchase of Class B shares during the preceding six years (or, in the case of
shares held by certain employer-sponsored benefit plans, three years). However,
no CDSC will be imposed to the extent that the net asset value of the shares
redeemed does not exceed: (a) the current net asset value of shares purchased
more than six years (or, in the case of shares held by certain
employer-sponsored benefit plans, three years) prior to the redemption, plus (b)
the current net asset value of shares purchased through reinvestment of
dividends or distributions of the Fund or another TCW/DW Fund (see "Shareholder
Services--Targeted Dividends"), plus (c) increases in the net asset value of the
investor's shares above the total amount of payments for the purchase of Fund
shares made during the preceding six (three) years. The CDSC will be paid to the
Distributor.
 
    In determining the applicability of the CDSC to each redemption, the amount
which represents an increase in the net asset value of the investor's shares
above the amount of the total payments for the purchase of shares within the
last six years (or, in the case of shares held by certain employer-sponsored
benefit plans, three years) will be redeemed first. In the event the redemption
amount exceeds such increase in value, the next portion of the amount redeemed
will be the amount which represents the net asset value of the investor's shares
purchased more than six (three) years prior to the redemption and/or shares
purchased through reinvestment of dividends or distributions. A portion of the
amount redeemed which exceeds an amount which represents both such increase in
value and the value of shares purchased more than six years (or, in the case of
shares held by certain employer-sponsored benefit plans, three years) prior to
the redemption and/or shares purchased through reinvestment of dividends or
distributions will be subject to a CDSC.
 
    The amount of the CDSC, if any, will vary depending on the number of years
from the time of payment for the purchase of Class B shares of the Fund until
the time of redemption of such shares. For purposes of determining the number of
years from the time of any payment for the purchase of shares, all payments made
during a month will be aggregated and deemed to have been made on the last day
of the month. The following table sets forth the rates of the CDSC applicable to
most Class B shares of the Fund:

    In determining the rate of the CDSC, it will be assumed that a redemption is
made of shares held by the investor for the longest period of time within the
applicable six-year or three-year period. This will result in any such CDSC
being imposed at the lowest possible rate. The CDSC will be imposed, in
accordance with the table shown above, on any redemptions within six years (or,
in the case of shares held by certain employer-sponsored benefit plans, three
years) of purchase which are in excess of these amounts and which redemptions do
not qualify for waiver of the CDSC, as described in the Prospectus.
 
LEVEL LOAD ALTERNATIVE--CLASS C SHARES
 
    Class C shares are sold without a sales charge but are subject to a CDSC of
1.0% on most redemptions made within one year after purchase, except in the
circumstances discussed in the Prospectus.
 
NO LOAD ALTERNATIVE--CLASS D SHARES
 
    Class D shares are offered without any sales charge on purchase or
redemption. Class D shares are offered only to those persons meeting the
qualifications set forth in the Prospectus.
 
SHAREHOLDER SERVICES
- --------------------------------------------------------------------------------
 
    SHAREHOLDER INVESTMENT ACCOUNT.  Upon purchase of shares of the Fund, a
Shareholder Investment Account is opened for the investor on the books of the
Fund, maintained by the Transfer Agent. This is an open account in which shares
owned by the investor are credited by the Transfer Agent in lieu of issuance of
a share certificate. If a share certificate is desired, it must be requested in
writing for each transaction. Certificates are issued only for full shares and
may be redeposited in the account at any time. There is no charge to the
investor for issuance of a certificate. No certificates will be issued for
fractional shares or to shareholders who have elected the Systematic Withdrawal
Plan for withdrawing cash from their accounts. Whenever a shareholder-instituted
transaction takes place in the Shareholder Investment Account, the shareholder
will be mailed a confirmation of the transaction from the Fund or from DWR or
other selected broker-dealer.
 
   
    AUTOMATIC INVESTMENT OF DIVIDENDS AND DISTRIBUTIONS.  All dividends and
capital gains distributions are automatically paid in full and fractional shares
of the applicable Class of the Fund, unless the shareholder requests that they
be paid in cash. Each purchase of shares of the Fund is made upon the condition
that the Transfer Agent is thereby automatically appointed as agent of the
investor to receive all dividends and capital gains distributions on shares
owned by the investor. Such dividends and distributions will be paid in shares
of the applicable Class of the Fund (or in cash if the shareholder so requests)
at the net asset value per share as of the close of business on the record date.
At any time an investor may request the Transfer Agent, in writing, to have
subsequent dividends and/or capital gains distributions paid to him or her in
cash rather than shares. To assure sufficient time to process the change, such
request should be received by the Transfer Agent at least five business days
prior to the record date of the dividend or distribution. In the case of
recently purchased shares for which registration instructions have not been
received on the record date, cash payments will be made to DWR or the other
selected broker-dealer, and which will be forwarded to the shareholder, upon the
receipt of proper instructions. It has been and remains the Fund's policy and
practice that, if checks for dividends or distributions paid in cash remain
uncashed, no interest will accrue on amounts represented by such uncashed
checks.
    
 
    EASYINVEST-SM-.  Shareholders may subscribe to EasyInvest, an automatic
purchase plan which provides for any amount from $100 to $5,000 to be
transferred automatically from a checking or savings account, or
 
                                       41
<PAGE>
   
following redemption of shares of a Dean Witter money market fund, on a
semi-monthly, monthly or quarterly basis, to the Transfer Agent for investment
in shares of the Fund. Shares purchased through EasyInvest will be added to the
shareholder's existing account at the net asset value calculated the same
business day the transfer of funds is effected (subject to any applicable sales
charges). For further information or to subscribe to EasyInvest, shareholders
should contact their DWR or other selected broker-dealer account executive or
the Transfer Agent.
    
 
    INVESTMENT OF DISTRIBUTIONS RECEIVED IN CASH.  As discussed in the
Prospectus, any shareholder who receives a cash payment representing a dividend
or capital gains distribution may invest such dividend or distribution in shares
of the applicable Class at the net asset value per share, without the imposition
of a CDSC upon redemption, by returning the check or the proceeds to the
Transfer Agent within 30 days after the payment date. If the shareholder returns
the proceeds of a dividend or distribution, such funds must be accompanied by a
signed statement indicating that the proceeds constitute a dividend or
distribution to be invested. Such investment will be made at the net asset value
per share next determined after receipt of the check or the proceeds by the
Transfer Agent.
 
    DIRECT INVESTMENTS THROUGH TRANSFER AGENT.  As discussed in the Prospectus,
shareholders may make additional investments in any Class of shares of the Fund
for which they qualify at any time by sending a check in any amount, not less
than $100, payable to TCW/DW Balanced Fund, and indicating the selected Class,
directly to the Transfer Agent. In the case of Class A shares, after deduction
of any applicable sales charge, the balance will be applied to the purchase of
Fund shares, and, in the case of shares of the other Classes, the entire amount
will be applied to the purchase of Fund shares, at the net asset value per share
next computed after receipt of the check of purchase payment by the Transfer
Agent. The shares so purchased will be credited to the investor's account.
 
    TARGETED DIVIDENDS-SM-.  In states where it is legally permissible to do so,
shareholders may also have all income dividends and capital gains distributions
automatically invested in shares of any Class of an open-end TCW/DW Fund other
than TCW/DW Balanced Fund or in another Class of TCW/DW Balanced Fund. Such
investment will be made as described above for automatic investment in shares of
the applicable Class of the Fund, at the net asset value per share of the
selected TCW/DW Fund as of the close of business of the payment date of the
dividend or distribution, and will begin to earn dividends, if any, in the
selected TCW/DW Fund the next business day. To participate in the Targeted
Dividends program, shareholders should contact their DWR or other selected
broker-dealer account executive or the Transfer Agent. Shareholders of the Fund
must be shareholders of the selected Class of the TCW/DW Fund targeted to
receive investments from dividends at the time they enter the Targeted Dividends
program. Investors should review the prospectus of the targeted TCW/ DW Fund
before entering the program.
 
    SYSTEMATIC WITHDRAWAL PLAN.  As discussed in the Prospectus, a systematic
withdrawal plan is available for shareholders who own or purchase shares of the
Fund having a minimum value of $10,000 based upon the then current net asset
value. The plan provides for monthly or quarterly (March, June, September and
December) checks in any dollar amount, not less than $25, or in any whole
percentage of the account balance, on an annualized basis. Any applicable CDSC
will be imposed on shares redeemed under the Withdrawal Plan (see "Purchase of
Fund Shares"). Therefore, any shareholder participating in the Withdrawal Plan
will have sufficient shares redeemed from his or her account so that the
proceeds (net of any applicable CDSC) to the shareholder will be the designated
monthly or quarterly amount.
 
    Withdrawal Plan payments should not be considered as dividends, yields or
income. If periodic withdrawal plan payments continuously exceed net investment
income and net capital gains, the shareholder's original investment will be
correspondingly reduced and ultimately exhausted.
 
    Each withdrawal constitutes a redemption of shares and any gain or loss
realized must be recognized for federal income tax purposes. Although the
shareholder may make additional investments of $2,500 or more under the
Withdrawal Plan, withdrawals made concurrently with purchases of additional
shares may be inadvisable because of sales charges which may be applicable to
purchases or redemptions of shares (see "Purchase of Fund Shares").
 
                                       42
<PAGE>
    The Transfer Agent acts as agent for the shareholder in tendering to the
Fund for redemption sufficient full and fractional shares to provide the amount
of the periodic withdrawal payment designated in the application. The shares
will be redeemed at their net asset value determined, at the shareholder's
option, on the tenth or twenty-fifth day (or next following business day) of the
relevant month or quarter and normally a check for the proceeds will be mailed
by the Transfer Agent within five business days after the date of redemption.
The Withdrawal Plan may be terminated at any time by the Fund.
 
    Any shareholder who wishes to have payments under the Withdrawal Plan made
to a third party or sent to an address other than the one listed on the account
must send complete written instructions to the Transfer Agent to enroll in the
Withdrawal Plan. The shareholder's signature on such instructions must be
guaranteed by an eligible guarantor acceptable to the Transfer Agent
(shareholders should contact the Transfer Agent for a determination as to
whether a particular institution is such an eligible guarantor). A shareholder
may, at any time, change the amount and interval of withdrawal payments through
his or her DWR or other selected broker-dealer account executive or by written
notification to the Transfer Agent. In addition, the party and/or the address to
which checks are mailed may be changed by written notification to the Transfer
Agent, with signature guarantees required in the manner described above. The
shareholder may also terminate the Withdrawal Plan at any time by written notice
to the Transfer Agent. In the event of such termination, the account will be
continued as a regular shareholder investment account. The shareholder may also
redeem all or part of the shares held in the Withdrawal Plan account (see
"Repurchases and Redemptions" in the Prospectus) at any time. Shareholders
wishing to enroll in the Withdrawal Plan should contact their account executive
or the Transfer Agent.
 
EXCHANGE PRIVILEGE
 
    As discussed in the Prospectus, the Fund makes available to its shareholders
an Exchange Privilege whereby shareholders of each Class of shares of the Fund
may exchange their shares for shares of the same Class of shares of any other
TCW/DW Multi-Class Fund without the imposition of any exchange fee. Shares may
also be exchanged for TCW/DW North American Government Income Trust and five
money market funds for which InterCapital serves as investment manager (the
foregoing six funds are hereinafter collectively referred to as the "Exchange
Funds"). Exchanges may be made after the shares of the fund acquired by purchase
(not by exchange or dividend reinvestment) have been held for thirty days. There
is no waiting period for exchanges of shares acquired by exchange or dividend
reinvestment. An exchange will be treated for federal income tax purposes the
same as a repurchase or redemption of shares, on which the shareholder may
realize a capital gain or loss.
 
    Shareholders utilizing the Fund's Exchange Privilege may subsequently
re-exchange such shares back to the Fund. However, no exchange privilege is
available between the Fund and any other fund managed by the Manager or
InterCapital, except for other TCW/DW Funds and the five money market funds
listed in the Prospectus.
 
    Any new account established through the Exchange Privilege will have the
same registration and cash dividend or dividend reinvestment plan as the present
account, unless the Transfer Agent receives written notification to the
contrary. For telephone exchanges, the exact registration of the existing
account and the account number must be provided.
 
    Any shares held in certificate form cannot be exchanged but must be
forwarded to the Transfer Agent and deposited into the shareholder's account
before being eligible for exchange. (Certificates mailed in for deposit should
not be endorsed.)
 
    As described below, and in the Prospectus under the caption "Purchase of
Fund Shares," a CDSC may be imposed upon a redemption, depending on a number of
factors, including the number of years from the time of purchase until the time
of redemption or exchange ("holding period"). When shares of a TCW/DW Multi-
Class Fund are exchanged for shares of an Exchange Fund, the exchange is
executed at no charge to the shareholder, without the imposition of the CDSC at
the time of the exchange. During the period of time the shareholder remains in
the Exchange Fund (calculated from the last day of the month in which the
Exchange Fund shares were acquired), the holding period or "year since purchase
payment made" is frozen. When shares
 
                                       43
<PAGE>
are redeemed out of the Exchange Fund, they will be subject to a CDSC which
would be based upon the period of time the shareholder held shares in a TCW/DW
Multi-Class Fund. However, in the case of shares exchanged into an Exchange
Fund, upon a redemption of shares which results in a CDSC being imposed, a
credit (not to exceed the amount of the CDSC) will be given in an amount equal
to the Exchange Fund 12b-1 distribution fees which are attributable to those
shares. Shareholders acquiring shares of an Exchange Fund pursuant to this
exchange privilege may exchange those shares back into a TCW/DW Multi-Class Fund
from the Exchange Fund, with no charge being imposed on such exchange. The
holding period previously frozen when shares were first exchanged for shares of
an Exchange Fund resumes on the last day of the month in which shares of a TCW/
DW Multi-Class Fund are reacquired. A CDSC is imposed only upon an ultimate
redemption, based upon the time (calculated as described above) the shareholder
was invested in a TCW/DW Multi-Class Fund.
 
    When shares initially purchased in a TCW/DW Multi-Class Fund are exchanged
for shares of a TCW/DW Multi-Class Fund or shares of an Exchange Fund, the date
of purchase of the shares of the fund exchanged into, for purposes of the CDSC
upon redemption, will be the last day of the month in which the shares being
exchanged were originally purchased. In allocating the purchase payments between
funds for purposes of the CDSC, the amount which represents the current net
asset value of shares at the time of the exchange which were (i) purchased more
than one, three or six years (depending on the CDSC schedule applicable to the
shares) prior to the exchange and (ii) originally acquired through reinvestment
of dividends or distributions (all such shares called "Free Shares"), will be
exchanged first. After an exchange, all dividends earned on shares in the
Exchange Fund will be considered Free Shares. If the exchanged amount exceeds
the value of such Free Shares, an exchange is made, on a block-by-block basis,
of non-Free Shares held for the longest period of time. Shares equal to any
appreciation in the value of non-Free Shares exchanged will be treated as Free
Shares, and the amount of the purchase payments for the non-Free Shares of the
fund exchanged into will be equal to the lesser of (a) the purchase payments
for, or (b) the current net asset value of, the exchanged non-Free Shares. If an
exchange between funds would result in exchange of only part of a particular
block of non-Free Shares, then shares equal to any appreciation in the value of
the block (up to the amount of the exchange) will be treated as Free Shares and
exchanged first, and the purchase payment for that block will be allocated on a
pro rata basis between the non-Free Shares of that block to be retained and the
non-Free Shares to be exchanged. The prorated amount of such purchase payment
attributable to the retained non-Free Shares will remain as the purchase payment
for such shares, and the amount of purchase payment for the exchanged non-Free
Shares will be equal to the lesser of (a) the prorated amount of the purchase
payment for, or (b) the current net asset value of, those exchanged non-Free
Shares. Based upon the procedures described in the CDSC Fund Prospectus under
the caption "Purchase of Fund Shares," any applicable CDSC will be imposed upon
the ultimate redemption of shares of any fund, regardless of the number of
exchanges since those shares were originally purchased.
 
    With respect to the redemption or repurchase of shares of the Fund, the
application of proceeds to the purchase of new shares in the Fund or any other
of the funds and the general administration of the Exchange Privilege, the
Transfer Agent acts as agent for the Distributor and for the shareholder's
selected broker-dealer, if any, in the performance of such functions.
 
    With respect to exchanges, redemptions or repurchases, the Transfer Agent
shall be liable for its own negligence and not for the default or negligence of
its correspondents or for losses in transit. The Fund shall not be liable for
any default or negligence of the Transfer Agent, the Distributor or any selected
broker-dealer.
 
    The Distributor and any selected broker-dealer have authorized and appointed
the Transfer Agent to act as their agent in connection with the application of
proceeds of any redemption of Fund shares to the purchase of shares of any other
fund and the general administration of the Exchange Privilege. No commission or
discounts will be paid to the Distributor or any selected broker-dealer for any
transactions pursuant to this Exchange Privilege.
 
    Exchanges are subject to the minimum investment requirement and any other
conditions imposed by each fund. (The minimum initial investment for the
Exchange Privilege account of each Class is $5,000 for Dean Witter Liquid Asset
Fund Inc., Dean Witter Tax-Free Daily Income Trust, Dean Witter New York
Municipal Money Market Trust and Dean Witter California Tax-Free Daily Income
Trust, although those funds may, at
 
                                       44
<PAGE>
their discretion, accept initial investments of as low as $1,000. The minimum
initial investment for the Exchange Privilege account of each Class for Dean
Witter U.S. Government Money Market Trust and all TCW/DW Funds is $1,000.) Upon
exchange into an Exchange Fund, the shares of the fund will be held in a special
Exchange Privilege Account separately from accounts of those shareholders who
have acquired their shares directly from that fund. As a result, certain
services normally available to shareholders of money market funds, including the
check writing feature, will not be available for funds held in that account.
 
    The Fund, each of the other TCW/DW Funds and and each of the money market
funds may limit the number of times this Exchange Privilege may be exercised by
any investor within a specified period of time. Also, the Exchange Privilege may
be terminated or revised at any time by the Fund and/or any of the funds for
which shares of the Fund have been exchanged, upon such notice as may be
required by applicable regulatory agencies (presently sixty days for termination
or material revision), provided that six months prior written notice of
termination will be given to the shareholders who hold shares of the Exchange
Funds, pursuant to this Exchange Privilege, and provided further that the
Exchange Privilege may be terminated or materially revised without notice at
times (a) when the New York Stock Exchange is closed for other than customary
weekends and holidays, (b) when trading on that Exchange is restricted, (c) when
an emergency exists as a result of which disposal by the Fund of securities
owned by it is not reasonably practicable or it is not reasonably practicable
for the Fund fairly to determine the value of its net assets, (d) during any
other period when the Securities and Exchange Commission by order so permits
(provided that applicable rules and regulations of the Securities and Exchange
Commission shall govern as to whether the conditions prescribed in (b) or (c)
exist) or (e) if the Fund would be unable to invest amounts effectively in
accordance with its investment objective, policies and restrictions.
Shareholders maintaining margin accounts with DWR or another selected
broker-dealer are referred to their account executives regarding restrictions on
exchange of shares of the Fund pledged in the margin account.
 
    For further information regarding the Fund's Exchange Privilege,
shareholders should contact their DWR or other selected broker-dealer account
executive or the Transfer Agent.
 
REPURCHASES AND REDEMPTIONS
- --------------------------------------------------------------------------------
 
    REDEMPTION.  As stated in the Prospectus, shares of each Class of the Fund
can be redeemed for cash at any time at the net asset value per share next
determined; however, such redemption proceeds will be reduced by the amount of
any applicable CDSC. If shares are held in a shareholder's account without a
share certificate, a written request for redemption to the Fund's Transfer Agent
at P.O. Box 983, Jersey City, NJ 07303 is required. If certificates are held by
the shareholder, the shares may be redeemed by surrendering the certificates
with a written request for redemption. The share certificate, or an accompanying
stock power, and the request for redemption, must be signed by the shareholder
or shareholders exactly as the shares are registered. Each request for
redemption, whether or not accompanied by a share certificate, must be sent to
the Fund's Transfer Agent, which will redeem the shares at their net asset value
next computed (see "Purchase of Fund Shares") after it receives the request, and
certificate, if any, in good order. Any redemption request received after such
computation will be redeemed at the next determined net asset value. The term
"good order" means that the share certificate, if any, and request for
redemption are properly signed, accompanied by any documentation required by the
Transfer Agent, and bear signature guarantees when required by the Fund or the
Transfer Agent. If redemption is requested by a corporation, partnership, trust
or fiduciary, the Transfer Agent may require that written evidence of authority
acceptable to the Transfer Agent be submitted before such request is accepted.
 
    Whether certificates are held by the shareholder or shares are held in a
shareholder's account, if the proceeds are to be paid to any person other than
the record owner, or if the proceeds are to be paid to a corporation (other than
the Distributor or a selected broker-dealer for the account of the shareholder),
partnership, trust or fiduciary, or sent to the shareholder at an address other
than the registered address, signatures must be guaranteed by an eligible
guarantor acceptable to the Transfer Agent (shareholders should contact the
Transfer Agent for a determination as to whether a particular institution is
such an eligible guarantor). A stock power may be obtained from any dealer or
commercial bank. The Fund may change the signature guarantee requirements from
time to time upon notice to shareholders, which may be by means of a revised
prospectus.
 
                                       45
<PAGE>
    REPURCHASE.  As stated in the Prospectus, DWR and other selected
broker-dealers are authorized to repurchase shares represented by a share
certificate which is delivered to any of their offices. Shares held in a
shareholder's account without a share certificate may also be repurchased by DWR
and other selected broker-dealers upon the telephonic request of the
shareholder. The repurchase price is the net asset value next computed after
such purchase order is received by DWR or other selected broker-dealer reduced
by any applicable CDSC.
 
   
    PAYMENT FOR SHARES REPURCHASED OR REDEEMED.  As discussed in the Prospectus,
payment for shares of any Class presented for repurchase or redemption will be
ordinarily made by check within seven days after receipt by the Transfer Agent
of the certificate and/or written request in good order. Such payment may be
postponed or the right of redemption suspended at times (a) when the New York
Stock Exchange is closed for other than customary weekends and holidays, (b)
when trading on that Exchange is restricted, (c) when an emergency exists as a
result of which disposal by the Fund of securities owned by it is not reasonably
practicable or it is not reasonably practicable for the Fund fairly to determine
the value of its net assets, or (d) during any other period when the Securities
and Exchange Commission by order so permits; provided that applicable rules and
regulations of the Securities and Exchange Commission shall govern as to whether
the conditions prescribed in (b) or (c) exist. If the shares to be redeemed have
recently been purchased by check and the check has not yet cleared, payment of
redemption proceeds may be delayed until the check has cleared (not more than
fifteen days from the time of receipt of the check by the Transfer Agent). It
has been and remains the Fund's policy and practice that, if checks for
redemption proceeds remain uncashed, no interest will accrue on amounts
represented by such uncashed checks. Shareholders maintaining margin accounts
with DWR or another selected broker-dealer are referred to their account
executive regarding restrictions on redemption of shares of the Fund pledged in
the margin account.
    
 
    TRANSFERS OF SHARES.  In the event a shareholder requests a transfer of any
shares to a new registration, such shares will be transferred without sales
charge at the time of transfer. With regard to the status of shares which are
either subject to the CDSC or free of such charge (and with regard to the length
of time shares subject to the charge have been held), any transfer involving
less than all of the shares in an account will be made on a pro rata basis (that
is, by transferring shares in the same proportion that the transferred shares
bear to the total shares in the account immediately prior to the transfer). The
transferred shares will continue to be subject to any applicable CDSC as if they
had not been so transferred.
 
    REINSTATEMENT PRIVILEGE.  As discussed in the Prospectus, a shareholder who
has had his or her shares redeemed or repurchased and has not previously
exercised this reinstatement privilege may within 35 days after the date of
redemption or repurchase reinstate any portion or all of the proceeds of such
redemption or repurchase in shares of the Fund in the same Class at the net
asset value next determined after a reinstatement request, together with such
proceeds, is received by the Transfer Agent.
 
    Exercise of the reinstatement privilege will not affect the federal income
tax treatment of any gain or loss realized upon the redemption or repurchase,
except that if the redemption or repurchase resulted in a loss and reinstatement
is made in shares of the Fund, some or all of the loss, depending on the amount
reinstated, will not be allowed as a deduction for federal income tax purposes,
but will be applied to adjust the cost basis of the shares acquired upon
reinstatement.
 
DIVIDENDS, DISTRIBUTIONS AND TAXES
- --------------------------------------------------------------------------------
 
    As discussed in the Prospectus, the Fund will determine either to distribute
or to retain all or part of any net long-term capital gains in any year for
reinvestment. If any such gains are retained, the Fund will pay federal income
tax thereon, and shareholders will be required to include such undistributed
gains in their taxable income and will be able to claim their share of the tax
paid by the Fund as a credit against their individual federal income tax.
 
    Gains or losses on sales of securities by the Fund will be long-term capital
gains or losses if the securities have been held by the Fund for more than
twelve months. Gains or losses on the sale of securities held for twelve months
or less will be short-term gains or losses.
 
    The Fund's transactions, if any, in options and futures contracts may be
subject to special provisions of the Internal Revenue Code that, among other
things, may affect the character of gains and losses realized by the Fund (i.e.,
may affect whether gains or losses are ordinary or capital), accelerate
recognition of income to the Fund and defer Fund losses. These rules could
therefore affect the character, amount and timing of distributions to
 
                                       46
<PAGE>
shareholders. These rules also (a) could require the Fund to mark-to-market
certain types of the positions in its portfolio (i.e., treat them as if they
were closed out) 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.
 
    Any dividend or capital gains distribution received by a shareholder from
any investment company will have the effect of reducing the net asset value of
the shareholder's stock in that company by the exact amount of the dividend or
capital gains distribution. Furthermore, capital gains distributions and
dividends are subject to federal income taxes. If the net asset value of the
shares should be reduced below a shareholder's cost as a result of the payment
of dividends or the distribution of realized net long-term capital gains, such
payment or distribution would be in part a return of the shareholder's
investment to the extent of such reduction below the shareholder's cost, but
nonetheless would be fully taxable at either ordinary or capital gain rates.
Therefore, an investor should consider the tax implications of purchasing Fund
shares immediately prior to a dividend or distribution record date.
 
    Shareholders are urged to consult their attorneys or tax advisers regarding
specific questions as to federal, state or local taxes.
 
PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
 
    As discussed in the Prospectus, from time to time the Fund may quote its
"yield" and/or its "total return" in advertisements and sales literature. These
figures are computed separately for Class A, Class B, Class C and Class D
shares. Prior to July 28, 1997 the Fund offered only one Class of shares.
Because all shares of the Fund held prior to such time (other than shares which
were acquired in exchange for shares of TCW/DW Funds offered with a CDSC and
shares acquired through reinvestment of dividends and distributions thereon)
have been designated Class C, certain historical performance data may be
restated to reflect the 1.0% CDSC imposed on most Class C shares redeemed within
one year after purchase.
 
   
    Yield is calculated for any 30-day period as follows: the amount of interest
and/or dividend income for each security in the Fund's portfolio is determined
in accordance with regulatory requirements; the total for the entire portfolio
constitutes the Fund's gross income for the period. Expenses accrued during the
period are subtracted to arrive at "net investment income." The resulting amount
is divided by the product of the maximum offering price per share on the last
day of the period multiplied by the average number of Fund shares outstanding
during the period that were entitled to dividends. This amount is added to 1 and
raised to the sixth power. 1 is then subtracted from the result and the
difference is multiplied by 2 to arrive at the annualized yield. The Fund's
yield for the 30-day period ended September 30, 1997 was 1.35% for Class A,
0.67% for Class B, 0.67% for Class C and 1.68% for Class D.
    
 
   
    The Fund's "average annual total return" represents an annualization of the
Fund's total return over a particular period and is computed by finding the
annual percentage rate which will result in the ending redeemable value of a
hypothetical $1,000 investment made at the beginning of a one, five or ten year
period, or for the period from the date of commencement of the Fund's
operations, if shorter than any of the foregoing. The ending redeemable value is
reduced by any CDSC at the end of the one, five or ten year or other period. For
the purpose of this calculation, it is assumed that all dividends and
distributions are reinvested. The formula for computing the average annual total
return involves a percentage obtained by dividing the ending redeemable value by
the amount of the initial investment, taking a root of the quotient (where the
root is equivalent to the number of years in the period) and subtracting 1 from
the result. The actual average annual total returns for Class C shares of the
Fund for the fiscal year ended September 30, 1997 and for the period October 29,
1993 (commencement of operations) through September 30, 1997 were 17.67% and
9.34%, respectively.
    
 
   
    For periods of less than one year, the Fund quotes its total return on a
non-annualized basis. Accordingly, the Fund may compute its aggregate total
return for each of Class A, Class B and Class D for specified periods by
determining the aggregate percentage rate which will result in the ending value
of a hypothetical $1,000 investment made at the beginning of the period. For the
purpose of this calculation, it is assumed that all dividends and distributions
are reinvested. The formula for computing aggregate total return involves a
percentage obtained by dividing the ending value by the initial $1,000
investment and subtracting 1 from the result. The ending redeemable value for
Class A reflects the imposition of the maximum front-end sales charge for Class
A. The ending redeemable value for Class B is reduced by any CDSC at the end of
the period. Based on the foregoing calculations, the total returns for the
period July 28, 1997 through September 30, 1997 were -4.66%, -4.52% and 0.65%
for Class A, Class B and Class D, respectively.
    
 
                                       47
<PAGE>
   
    In addition to the foregoing, the Fund may advertise its total return for
each Class over different periods of time by means of aggregate, year-by-year or
other types of total return figures. Such calculations may or may not reflect
the imposition of the maximum front-end sales charge for Class A or the
deduction of the CDSC for each of Class B and Class C which, if reflected, would
reduce the performance quoted. For example, the average annual total return of
the Fund may be calculated in the manner described above, but without deduction
for any applicable sales charge. Based upon the foregoing, the actual average
annual total returns of Class C for the fiscal year ended September 30, 1997 and
for the period October 29, 1993 through September 30, 1997 were 18.67% and
9.34%, respectively. In addition, the Fund may compute its aggregate total
return for specified periods by determining the aggregate percentage rate which
will result in the ending value of a hypothetical $1,000 investment made at the
beginning of the period. For the purpose of this calculation, it is assumed that
all dividends and distributions are reinvested. The formula for computing
aggregate total return involves a percentage obtained by dividing the ending
value (without the reduction for any sales charge) by the initial $1,000
investment and subtracting 1 from the result. Based on the foregoing calculation
the actual total returns for Class C for the fiscal year ended September 30,
1997 and the period October 29, 1993 through September 30, 1997 were 18.67% and
41.93%, respectively. Based on the foregoing calculations, the total returns for
Class A, Class B, and Class D for the period July 28, 1997 through September 30,
1997 were 0.62%, 0.48% and 0.65%, respectively.
    
 
   
    The Fund may also advertise the growth of hypothetical investments of
$10,000, $50,000 or $100,000 in each Class of shares of the Fund by adding 1 to
the Fund's aggregate total return to date (expressed as a decimal and without
taking into account the effect of any applicable CDSC) and multiplying by
$9,475, $48,000 and $97,000 in the case of Class A (investments of $10,000,
$50,000 or $100,000 adjusted for the initial sales charge), or by $10,000,
$50,000 and $100,000 in the case of each of Class B, Class C and Class D, as the
case may be. Investments of $10,000, $50,000 and $100,000 in the Fund at
inception would have grown or declined to the following amounts at September 30,
1997.

DESCRIPTION OF SHARES
- --------------------------------------------------------------------------------
 
    The shareholders of the Fund are entitled to a full vote for each full share
held. The Trustees have been elected by InterCapital as the sole shareholder of
the Fund or, in the case of Messrs. Schroeder and Stern, by the other Trustees
on April 20, 1995. The Trustees themselves have the power to alter the number
and the terms of office of the Trustees, and they may at any time lengthen their
own terms or make their terms of unlimited duration and appoint their own
successors, provided that always at least a majority of the Trustees has been
elected by the shareholders of the Fund. Under certain circumstances the
Trustees may be removed by action of the Trustees. The shareholders also have
the right to remove the Trustees following a meeting called for that purpose
requested in writing by the record holders of not less than ten percent of the
Fund's outstanding shares. The voting rights of shareholders are not cumulative,
so that holders of more than 50 percent of the shares voting can, if they
choose, elect all Trustees being selected, while the holders of the remaining
shares would be unable to elect any Trustees.
 
    The Declaration of Trust permits the Trustees to authorize the creation of
additional series of shares (the proceeds of which would be invested in
separate, independently managed portfolios) and additional classes of shares
within any series. The Trustees have not presently authorized any such
additional series or classes of shares other than as set forth in the
Prospectus.
 
    The Declaration of Trust provides that no Trustee, officer, employee or
agent of the Fund is liable to the Fund or to a shareholder, nor is any Trustee,
officer, employee or agent liable to any third persons in connection with the
affairs of the Fund, except as such liability may arise from his own bad faith,
willful misfeasance, gross negligence, or reckless disregard of his duties. It
also provides that all third persons shall look solely to the Fund's property
for satisfaction of claims arising in connection with the affairs of the Fund.
With the exceptions stated, the Declaration of
 
                                       48
<PAGE>
Trust provides that a Trustee, officer, employee or agent is entitled to be
indemnified against all liabilities in connection with the affairs of the Fund.
 
    The Fund is authorized to issue an unlimited number of shares of beneficial
interest. The Fund shall be of unlimited duration subject to the provisions in
the Declaration of Trust concerning termination by action of the shareholders.

TCW/DW BALANCED FUND
REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE SHAREHOLDERS AND TRUSTEES
OF TCW/DW BALANCED FUND
 
In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of TCW/DW Balanced Fund (the "Fund")
at September 30, 1997, the results of its operations for the year then ended,
the changes in its net assets for each of the two years in the period then ended
and the financial highlights for each of the periods presented, in conformity
with generally accepted accounting principles. These financial statements and
financial highlights (hereafter referred to as "financial statements") are the
responsibility of the Fund's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at September 30, 1997 by
correspondence with the custodian, provide a reasonable basis for the opinion
expressed above.
 
As described in Note 8 to the financial statements, the Fund's Board of Trustees
has approved, subject to the consent of the Fund's shareholders, a
reorganization plan whereby the Fund would be merged into Dean Witter Balanced
Growth Fund.

NOTES TO FINANCIAL STATEMENTS SEPTEMBER 30, 1997
 
1. ORGANIZATION AND ACCOUNTING POLICIES
 
TCW/DW Balanced Fund (the "Fund") is registered under the Investment Company Act
of 1940, as amended (the "Act"), as a diversified, open-end management
investment company. The Fund's investment objective is to achieve a high total
return through a combination of income and capital appreciation. The Fund seeks
to achieve its objective by investing in a diversified portfolio of common
stocks and investment grade fixed-income securities. The Fund was organized as a
Massachusetts business trust on March 2, 1993 and commenced operations on
October 29, 1993. On July 28, 1997, the Fund commenced offering three additional
classes of shares, with the then current shares, other than shares which were
acquired in exchange for shares of Funds for which Dean Witter Services Company
Inc. serves as Manager and TCW Funds Management, Inc. serves as Adviser ("TCW/DW
Funds") offered with a contingent deferred sale charge ("CDSC") and shares
acquired through reinvestment of dividends and distributions thereon, have been
designated Class C shares. Shares held prior to July 28, 1997 which were
acquired in exchange for shares of a TCW/DW Fund sold with a CDSC, including
shares acquired through reinvestment of dividends and distributions thereon,
have been designated Class B shares.
 
The Fund offers Class A shares, Class B shares, Class C shares and Class D
shares. The four classes are substantially the same except that most Class A
shares are subject to a sales charge imposed at the time of purchase, some Class
A shares, and most Class B shares and Class C shares are subject to a contingent
deferred sales charge imposed on shares redeemed within one year, six years and
one year, respectively. Class D shares are not subject to a sales charge.
Additionally, Class A shares, Class B shares and Class C shares incur
distribution expenses.
 
The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures. Actual results could differ from
those estimates.
 
The following is a summary of significant accounting policies:
 
A. VALUATION OF INVESTMENTS --  (1) an equity security listed or traded on the
New York, American, other domestic or foreign stock exchange is valued at its
latest sale price on that exchange prior to the time when assets are valued; if
there were no sales that day, the security is valued at the latest bid price (in
cases where securities are traded on more than one exchange, the securities are
valued on the exchange designated as the primary market pursuant to procedures
adopted by the Trustees); (2) all other portfolio securities for which
over-the-counter market quotations are readily available are valued at the
latest available bid price prior to the time of valuation; (3) when market
quotations are
 
                                       59
<PAGE>
TCW/DW BALANCED FUND
NOTES TO FINANCIAL STATEMENTS SEPTEMBER 30, 1997, CONTINUED
 
not readily available, including circumstances under which it is determined by
TCW Funds Management, Inc. (the "Adviser") that sale and bid prices are not
reflective of a security's market value, portfolio securities are valued at
their fair value as determined in good faith under procedures established by and
under the general supervision of the Trustees (valuation of debt securities for
which market quotations are not readily available may be based upon current
market prices of securities which are comparable in coupon, rating and maturity
or an appropriate matrix utilizing similar factors); (4) certain portfolio
securities may be valued by an outside pricing service approved by the Trustees.
The pricing service may utilize a matrix system incorporating security quality,
maturity and coupon as the evaluation model parameters, and/or research and
evaluations by its staff, including review of broker-dealer market price
quotations, if available, in determining what it believes is the fair valuation
of the portfolio securities valued by such pricing service; and (5) short-term
debt securities having a maturity date of more than sixty days at time of
purchase are valued on a mark-to-market basis until sixty days prior to maturity
and thereafter at amortized cost based on their value on the 61st day.
Short-term debt securities having a maturity date of sixty days or less at the
time of purchase are valued at amortized cost.
 
B. ACCOUNTING FOR INVESTMENTS -- Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). Realized gains and
losses on security transactions are determined by the identified cost method.
Dividend income and other distributions are recorded on the ex-dividend date
except for certain dividends on foreign securities which are recorded as soon as
the Fund is informed after the ex-dividend date. Discounts are accreted over the
life of the respective securities. Interest income is accrued daily.
 
C. MULTIPLE CLASS ALLOCATIONS -- Investment income, expenses (other than
distribution fees), and realized and unrealized gains and losses are allocated
to each class of shares based upon the relative net asset value on the date such
items are recognized. Distribution fees are charged directly to the respective
class.
 
D. FEDERAL INCOME TAX STATUS -- It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute all of its taxable income to its shareholders.
Accordingly, no federal income tax provision is required.
 
E. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- The Fund records dividends and
distributions to its shareholders on the record date. The amount of dividends
and distributions from net investment income and net realized capital gains are
determined in accordance with federal income tax regulations which may differ
from generally accepted accounting principles. These "book/tax"

differences are either considered temporary or permanent in nature. To the
extent these differences are permanent in nature, such amounts are reclassified
within the capital accounts based on their federal tax-basis treatment;
temporary differences do not require reclassification. Dividends and
distributions which exceed net investment income and net realized capital gains
for financial reporting purposes but not for tax purposes are reported as
dividends in excess of net investment income or distributions in excess of net
realized capital gains. To the extent they exceed net investment income and net
realized capital gains for tax purposes, they are reported as distributions of
paid-in-capital.
 
F. ORGANIZATIONAL EXPENSES -- Dean Witter InterCapital Inc., an affiliate of
Dean Witter Services Company, Inc. (the "Manager"), paid the organizational
expenses of the Fund in the amount of $180,493 which have been reimbursed for
the full amount thereof. Such expenses have been deferred and are being
amortized on the straight-line method over a period not to exceed five years
from the commencement of operations.
 
2. MANAGEMENT AGREEMENT
 
Pursuant to a Management Agreement, the Fund pays the Manager a management fee,
accrued daily and payable monthly, by applying the annual rate of 0.45% to the
net assets of the Fund determined as of the close of each business day.
 
Under the terms of the Agreement, the Manager maintains certain of the Fund's
books and records and furnishes, at its own expense, office space, facilities,
equipment, clerical, bookkeeping and certain legal services and pays the
salaries of all personnel, including officers of the Fund who are employees of
the Manager. The Manager also bears the cost of telephone services, heat, light,
power and other utilities provided to the Fund.
 
3. INVESTMENT ADVISORY AGREEMENT
 
Pursuant to an Investment Advisory Agreement, the Fund pays the Adviser an
advisory fee, accrued daily and payable monthly, by applying the annual rate of
0.30% to the net assets of the Fund determined as of the close of each business
day.
 
Under the terms of the Agreement, the Fund has retained the Adviser to invest
the Fund's assets, including placing orders for the purchase and sale of
portfolio securities. The Adviser obtains and evaluates such information and
advice relating to the economy, securities markets, and specific
 
                                       61

securities as it considers necessary or useful to continuously manage the assets
of the Fund in a manner consistent with its investment objective. In addition,
the Adviser pays the salaries of all personnel, including officers of the Fund,
who are employees of the Adviser.
 
4. PLAN OF DISTRIBUTION
 
Shares of the Fund are distributed by Dean Witter Distributors Inc. (the
"Distributor"), an affiliate of the Manager. The Fund has adopted a Plan of
Distribution (the "Plan") pursuant to Rule 12b-1 under the Act. The Plan
provides that the Fund will pay the Distributor a fee which is accrued daily and
paid monthly at the following annual rates: (i) Class A--0.25% of the average
daily net assets of Class A; (ii) Class B--1.0% of the average daily net assets
of Class B; and (iii) Class C--1.0% of the average daily net assets of Class C.
In the case of Class A shares, amounts paid under the Plan are paid to the
Distributor for services provided. In the case of Class B and Class C shares,
amounts paid under the Plan are paid to the Distributor for services provided
and the expenses borne by it and others in the distribution of the shares of
these Classes, including the payment of commissions for sales of these Classes
and incentive compensation to, and expenses of, the account executives of Dean
Witter Reynolds Inc. ("DWR"), an affiliate of the Manager and Distributor, and
others who engage in or support distribution of the shares or who service
shareholder accounts, including overhead and telephone expenses; printing and
distribution of prospectuses and reports used in connection with the offering of
these shares to other than current shareholders; and preparation, printing and
distribution of sales literature and advertising materials. In addition, the
Distributor may utilize fees paid pursuant to the Plan, in the case of Class B
shares, to compensate DWR and other selected broker-dealers for their
opportunity costs in advancing such amounts, which compensation would be in the
form of a carrying charge on any unreimbursed expenses.
 
In the case of Class B shares, provided that the Plan continues in effect, any
cumulative expenses incurred by the Distributor but not yet recovered may be
recovered through the payment of future distribution fees from the Fund pursuant
to the Plan and contingent deferred sales charges paid by investors upon
redemption of Class B shares. Although there is no legal obligation for the Fund
to pay expenses incurred in excess of payments made to the Distributor under the
Plan and the proceeds of contingent deferred sales charges paid by investors
upon redemption of shares, if for any reason the Plan is terminated, the
Trustees will consider at that time the manner in which to treat such expenses.
The Distributor has advised the Fund that there were no such excess amounts at
September 30, 1997.

NOTES TO FINANCIAL STATEMENTS SEPTEMBER 30, 1997, CONTINUED
 
In the case of Class A shares and Class C shares, expenses incurred pursuant to
the Plan in any calendar year in excess of 0.25% or 1.0% of the average daily
net assets of Class A or Class C, respectively, will not be reimbursed by the

           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         Fixed-income securities 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 fixed-income securities. They are rated lower than the best fixed-income
           securities 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          Fixed-income securities 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        Fixed-income securities 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 fixed-income securities lack outstanding investment
           characteristics and in fact have speculative characteristics as well.
           Fixed-income securities rated Aaa, Aa, A and Baa are considered investment grade.
</TABLE>
 
    RATING REFINEMENTS:  Moody's may apply numerical modifiers, 1, 2, and 3 in
each generic rating classification in its fixed-income security rating system.
The modifier 1 indicates that the security ranks in the higher end of its
generic rating category; the modifier 2 indicates a mid-range ranking; and a
modifier 3 indicates that the issue ranks in the lower end of its generic rating
category.
 
                            COMMERCIAL PAPER RATINGS
 
    Moody's Commercial Paper ratings are opinions of the ability to repay
punctually promissory obligations not having an original maturity in excess of
nine months. The ratings apply to Municipal Commercial Paper as well as taxable
Commercial Paper. Moody's employs the following three designations, all judged
to be investment grade, to indicate the relative repayment capacity of rated
issuers: Prime-1, Prime-2, Prime-3.
 
    Issuers rated Prime-1 have a superior capacity for repayment of short-term
promissory obligations. Issuers rated Prime-2 have a strong capacity for
repayment of short-term promissory obligations; and Issuers rated Prime-3 have
an acceptable capacity for repayment of short-term promissory obligations.
Issuers rated Not Prime do not fall within any of the Prime rating categories.
 
STANDARD & POOR'S CORPORATION ("STANDARD & POOR'S")
 
                         FIXED-INCOME SECURITY RATINGS
    A Standard & Poor's fixed-income security rating is a current assessment of
the creditworthiness of an obligor with respect to a specific obligation. This
assessment may take into consideration obligors such as guarantors, insurers, or
lessees.
 
    The ratings are based on current information furnished by the issuer or
obtained by Standard & Poor's from other sources it considers reliable. The
ratings are based, in varying degrees, on the following considerations: (1)
likelihood of default-capacity and willingness of the obligor as to the timely
payment of interest and repayment of principal in accordance with the terms of
the obligation; (2) nature of and provisions of the
 
                                       68
<PAGE>
obligation; and (3) protection afforded by, and relative position of, the
obligation in the event of bankruptcy, reorganization or other arrangement under
the laws of bankruptcy and other laws affecting creditors' rights.
 
    Standard & Poor's does not perform an audit in connection with any rating
and may, on occasion, rely on unaudited financial information. The ratings may
be changed, suspended or withdrawn as a result of changes in, or unavailability
of, such information, or for other reasons.
 
<TABLE>
<S>        <C>
AAA        Fixed-income securities rated "AAA" have the highest rating assigned by Standard &
           Poor's. Capacity to pay interest and repay principal is extremely strong.
AA         Fixed-income securities rated "AA" have a very strong capacity to pay interest and
           repay principal and differs from the highest-rated issues only in small degree.
A          Fixed-income securities rated "A" have a strong capacity to pay interest and repay
           principal although they are somewhat more susceptible to the adverse effects of
           changes in circumstances and economic conditions than fixed-income securities in
           higher-rated categories.
BBB        Fixed-income securities rated "BBB" are 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 fixed-income
           securities in this category than for fixed-income securities in higher-rated
           categories.
           Fixed-income securities rated AAA, AA, A and BBB are considered investment grade.
           Plus (+) or minus (-): The rating may be modified by the addition of a plus or
           minus sign to show relative standing with the major ratings categories.
</TABLE>
 
                            COMMERCIAL PAPER RATINGS
 
   
    Standard and Poor's commercial paper rating is a current assessment of the
likelihood of timely payment of debt having an original maturity of no more than
365 days. The commercial paper rating is not a recommendation to purchase or
sell a security. The ratings are based upon current information furnished by the
issuer or obtained by Standard and Poor's from other sources it considers
reliable. The ratings may be changed, suspended, or withdrawn as a result of
changes in or unavailability of such information. Ratings are graded into group
categories, ranging from "A" for the highest quality obligations to "D" for the
lowest. Ratings are applicable to both taxable and tax-exempt commercial paper.
The categories are as follows:
    
 
    Issues assigned A ratings are regarded as having the greatest capacity for
timely payment. Issues in this category are further refined with the designation
1, 2, and 3 to indicate the relative degree of safety.
 
   
<TABLE>
<S>        <C>
A-1        indicates that the degree of safety regarding timely payment is very strong.
A-2        indicates capacity for timely payment on issues with this designation is strong.
           However, the relative degree of safety is not as overwhelming as for issues
           designated "A-1."
A-3        indicates a satisfactory capacity for timely payment. Obligations carrying this
           designation are, however, somewhat more vulnerable to the adverse effects of changes
           in circumstances than obligations carrying the higher designations.

Item 27. Indemnification.

     Pursuant to Section 5.3 of the Registrant's Declaration of Trust and under
Section 4.8 of the Registrant's By-Laws, the indemnification of the Registrant's
trustees, officers, employees and agents is permitted if it is determined that
they acted under the belief that their actions were in or not opposed to the
best interest of the Registrant, and, with respect to any criminal proceeding,
they had reasonable cause to believe their conduct was not unlawful.  In
addition, indemnification is permitted only if it is determined that the actions
in question did not render them liable by reason of willful misfeasance, bad
faith or gross negligence in the performance of their duties or by reason of
reckless disregard of their obligations and duties to the Registrant.  Trustees,
officers, employees and agents will be indemnified for the expense of litigation
if it is determined that they are entitled to indemnification against any
liability established in such litigation.  The Registrant may also advance money
for these expenses provided that they give their undertakings to repay the
Registrant unless their conduct is later determined to permit indemnification.


                                      2
<PAGE>


     Pursuant to Section 5.2 of the Registrant's Declaration of Trust and
paragraph 8 of the Registrant's Management and Advisory Agreements, none of the
Manager, the Adviser or any trustee, officer, employee or agent of the
Registrant shall be liable for any action or failure to act, except in the case
of bad faith, willful misfeasance, gross negligence or reckless disregard of
duties to the Registrant.

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

     The Registrant hereby undertakes that it will apply the indemnification
provision of its by-laws in a manner consistent with Release 11330 of the
Securities and Exchange Commission under the Investment Company Act of 1940, so
long as the interpretation of Sections 17(h) and 17(i) of such Act remains in
effect.

     Registrant, in conjunction with the Manager, Registrant's Trustees, and
other registered investment management companies managed by the Manager,
maintains insurance on behalf of any person who is or was a Trustee, officer,
employee, or agent of Registrant, or who is or was serving at the request of
Registrant as a trustee, director, officer, employee or agent of another trust
or corporation, against any liability asserted against him and incurred by him
or arising out of his position.  However, in no event will Registrant maintain
insurance to indemnify any such person for any act for which Registrant itself
is not permitted to indemnify him.

                             TCW/DW BALANCED FUND
                 AMENDED AND RESTATED AS OF OCTOBER 23, 1997

                                  ARTICLE I
                                 DEFINITIONS

   The terms "COMMISSION," "DECLARATION," "DISTRIBUTOR," "INVESTMENT
ADVISER," "MAJORITY SHAREHOLDER VOTE," "1940 ACT," "SHAREHOLDER," "SHARES,"
"TRANSFER AGENT," "TRUST," "TRUST PROPERTY," and "TRUSTEES" have the
respective meanings given them in the Declaration of Trust of TCW/DW Balanced
Fund dated March 1, 1993.

                                  ARTICLE II
                                   OFFICES

   SECTION 2.1. PRINCIPAL OFFICE. Until changed by the Trustees, the
principal office of the Trust in the Commonwealth of Massachusetts shall be
in the City of Boston, County of Suffolk.

   SECTION 2.2. OTHER OFFICES. In addition to its principal office in the
Commonwealth of Massachusetts, the Trust may have an office or offices in the
City of New York, State of New York, and at such other places within and
without the Commonwealth as the Trustees may from time to time designate or
the business of the Trust may require.

                                 ARTICLE III
                            SHAREHOLDERS' MEETINGS

   SECTION 3.1. PLACE OF MEETINGS. Meetings of Shareholders shall be held at
such place, within or without the Commonwealth of Massachusetts, as may be
designated from time to time by the Trustees.

   SECTION 3.2. MEETINGS. Meetings of Shareholders of the Trust shall be held
whenever called by the Trustees or the President of the Trust and whenever
election of a Trustee or Trustees by Shareholders is required by the
provisions of Section 16(a) of the 1940 Act, for that purpose. Meetings of
Shareholders shall also be called by the Secretary upon the written request
of the holders of Shares entitled to vote not less than ten percent (10%) of
all the votes entitled to be cast at such meeting, except to the extent
otherwise required by Section 16(c) of the 1940 Act, as made applicable to
the Trust by the provisions of Section 2.3 of the Declaration. Such request
shall state the purpose or purposes of such meeting and the matters proposed
to be acted on thereat. Except to the extent otherwise required by Section
16(c) of the 1940 Act, as made applicable to the Trust by the provisions of
Section 2.3 of the Declaration, the Secretary shall inform such Shareholders
of the reasonable estimated cost of preparing and mailing such notice of the
meeting, and upon payment to the Trust of such costs, the Secretary shall
give notice stating the purpose or purposes of the meeting to all entitled to
vote at such meeting. No meeting need be called upon the request of the
holders of Shares entitled to cast less than a majority of all votes entitled
to be cast at such meeting, to consider any matter which is substantially the
same as a matter voted upon at any meeting of Shareholders held during the
preceding twelve months.

   SECTION 3.3. NOTICE OF MEETINGS. Written or printed notice of every
Shareholders' meeting stating the place, date, and purpose or purposes
thereof, shall be given by the Secretary not less than ten (10) nor more than
ninety (90) days before such meeting to each Shareholder entitled to vote at
such meeting. Such notice shall be deemed to be given when deposited in the
United States mail, postage prepaid, directed to the Shareholder at his
address as it appears on the records of the Trust.

   SECTION 3.4. QUORUM AND ADJOURNMENT OF MEETINGS. Except as otherwise
provided by law, by the Declaration or by these By-Laws, at all meetings of
Shareholders, the holders of a majority of the Shares issued and outstanding
and entitled to vote thereat, present in person or represented by proxy,
shall be

                                1
<PAGE>
requisite and shall constitute a quorum for the transaction of business. In
the absence of a quorum, the Shareholders present or represented by proxy and
entitled to vote thereat shall have the power to adjourn the meeting from
time to time. The Shareholders present in person or represented by proxy at
any meeting and entitled to vote thereat also shall have the power to adjourn
the meeting from time to time if the vote required to approve or reject any
proposal described in the original notice of such meeting is not obtained
(with proxies being voted for or against adjournment consistent with the
votes for and against the proposal for which the required vote has not been
obtained). The affirmative vote of the holders of a majority of the Shares
then present in person or represented by proxy shall be required to adjourn
any meeting. Any adjourned meeting may be reconvened without further notice
or change in record date. At any reconvened meeting at which a quorum shall
be present, any business may be transacted that might have been transacted at
the meeting as originally called.

   SECTION 3.5. VOTING RIGHTS, PROXIES. At each meeting of Shareholders, each
holder of record of Shares entitled to vote thereat shall be entitled to one
vote in person or by proxy, executed in writing by the Shareholder or his
duly authorized attorney-in-fact, for each Share of beneficial interest of
the Trust and for the fractional portion of one vote for each fractional
Share entitled to vote so registered in his name on the records of the Trust
on the date fixed as the record date for the determination of Shareholders
entitled to vote at such meeting. No proxy shall be valid after eleven months
from its date, unless otherwise provided in the proxy. At all meetings of
Shareholders, unless the voting is conducted by inspectors, all questions
relating to the qualification of voters and the validity of proxies and the
acceptance or rejection of votes shall be decided by the chairman of the
meeting. Pursuant to a resolution of a majority of the Trustees, proxies may
be solicited in the name of one or more Trustees or Officers of the Trust.

   SECTION 3.6. VOTE REQUIRED. Except as otherwise provided by law, by the
Declaration of Trust, or by these By-Laws, at each meeting of Shareholders at
which a quorum is present, all matters shall be decided by Majority
Shareholder Vote.

   SECTION 3.7. INSPECTORS OF ELECTION. In advance of any meeting of
Shareholders, the Trustees may appoint Inspectors of Election to act at the
meeting or any adjournment thereof. If Inspectors of Election are not so
appointed, the chairman of any meeting of Shareholders may, and on the
request of any Shareholder or his proxy shall, appoint Inspectors of Election
of the meeting. In case any person appointed as Inspector fails to appear or
fails or refuses to act, the vacancy may be filled by appointment made by the
Trustees in advance of the convening of the meeting or at the meeting by the
person acting as chairman. The Inspectors of Election shall determine the
number of Shares outstanding, the Shares represented at the meeting, the
existence of a quorum, the authenticity, validity and effect of proxies,
shall receive votes, ballots or consents, shall hear and determine all
challenges and questions in any way arising in connection with the right to
vote, shall count and tabulate all votes or consents, determine the results,
and do such other acts as may be proper to conduct the election or vote with
fairness to all Shareholders. On request of the chairman of the meeting, or
of any Shareholder or his proxy, the Inspectors of Election shall make a
report in writing of any challenge or question or matter determined by them
and shall execute a certificate of any facts found by them.

   SECTION 3.8. INSPECTION OF BOOKS AND RECORDS. Shareholders shall have such
rights and procedures of inspection of the books and records of the Trust as
are granted to Shareholders under the Corporations and Associations Law of
the State of Maryland.

   SECTION 3.9. ACTION BY SHAREHOLDERS WITHOUT MEETING. Except as otherwise
provided by law, the provisions of these By-Laws relating to notices and
meetings to the contrary notwithstanding, any action required or permitted to
be taken at any meeting of Shareholders may be taken without a meeting if a
majority of the Shareholders entitled to vote upon the action consent to the
action in writing and such consents are filed with the records of the Trust.
Such consent shall be treated for all purposes as a vote taken at a meeting
of Shareholders.

   SECTION 3.10. PRESENCE AT MEETINGS. Presence at meetings of shareholders
requires physical attendance by the shareholder or his or her proxy at the
meeting site and does not encompass attendance by telephonic or other
electronic means.

                                  ARTICLE IV
                                   TRUSTEES

   SECTION 4.1. MEETINGS OF THE TRUSTEES. The Trustees may in their
discretion provide for regular or special meetings of the Trustees. Regular
meetings of the Trustees may be held at such time and place as shall be
determined from time to time by the Trustees without further notice. Special
meetings of the Trustees may be called at any time by the Chairman and shall
be called by the Chairman or the Secretary upon the written request of any
two (2) Trustees.

   SECTION 4.2. NOTICE OF SPECIAL MEETINGS. Written notice of special
meetings of the Trustees, stating the place, date and time thereof, shall be
given not less than two (2) days before such meeting to each Trustee,
personally, by telegram, by mail, or by leaving such notice at his place of
residence or usual place of business. If mailed, such notice shall be deemed
to be given when deposited in the United States mail, postage prepaid,
directed to the Trustee at his address as it appears on the records of the
Trust. Subject to the provisions of the 1940 Act, notice or waiver of notice
need not specify the purpose of any special meeting.

   SECTION 4.3. TELEPHONE MEETINGS. Subject to the provisions of the 1940
Act, any Trustee, or any member or members of any committee designated by the
Trustees, may participate in a meeting of the Trustees, or any such
committee, as the case may be, by means of a conference telephone or similar
communications equipment if all persons participating in the meeting can hear
each other at the same time. Participation in a meeting by these means
constitutes presence in person at the meeting.

   SECTION 4.4. QUORUM, VOTING AND ADJOURNMENT OF MEETINGS. At all meetings
of the Trustees, a majority of the Trustees shall be requisite to and shall
constitute a quorum for the transaction of business. If a quorum is present,
the affirmative vote of a majority of the Trustees present shall be the act
of the Trustees, unless the concurrence of a greater proportion is expressly
required for such action by law, the Declaration or these By-Laws. If at any
meeting of the Trustees there be less than a quorum present, the Trustees
present thereat may adjourn the meeting from time to time, without notice
other than announcement at the meeting, until a quorum shall have been
obtained.

   SECTION 4.5. ACTION BY TRUSTEES WITHOUT MEETING. The provisions of these
By-Laws covering notices and meetings to the contrary notwithstanding, and
except as required by law, any action required or permitted to be taken at
any meeting of the Trustees may be taken without a meeting if a consent in
writing setting forth the action shall be signed by all of the Trustees
entitled to vote upon the action and such written consent is filed with the
minutes of proceedings of the Trustees.

   SECTION 4.6. EXPENSES AND FEES. Each Trustee may be allowed expenses, if
any, for attendance at each regular or special meeting of the Trustees, and
each Trustee who is not an officer or employee of the Trust or of its
investment manager or underwriter or of any corporate affiliate of any of
said persons shall receive for services rendered as a Trustee of the Trust
such compensation as may be fixed by the Trustees. Nothing herein contained
shall be construed to preclude any Trustee from serving the Trust in any
other capacity and receiving compensation therefor.

   SECTION 4.7. EXECUTION OF INSTRUMENTS AND DOCUMENTS AND SIGNING OF CHECKS
AND OTHER OBLIGATIONS AND TRANSFERS. All instruments, documents and other
papers shall be executed in the name and on behalf of the Trust and all
checks, notes, drafts and other obligations for the payment of money by the
Trust shall be signed, and all transfer of securities standing in the name of
the Trust shall be executed, by the Chairman, the President, any Vice
President or the Treasurer or by any one or more officers or agents of the
Trust as shall be designated for that purpose by vote of the Trustees;
notwithstanding the above, nothing in this Section 4.7 shall be deemed to
preclude the electronic authorization, by designated persons, of the Trust's
Custodian (as described herein in Section 9.1) to transfer assets of the
Trust, as provided for herein in Section 9.1.

   SECTION 4.8. INDEMNIFICATION OF TRUSTEES, OFFICERS, EMPLOYEES AND
AGENTS. (a) The Trust shall indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending, or completed
action, suit or proceeding, whether civil, criminal, administrative or
investigative

                                3
<PAGE>
(other than an action by or in the right of the Trust) by reason of the fact
that he is or was a Trustee, officer, employee, or agent of the Trust. The
indemnification shall be against expenses, including attorneys' fees,
judgments, fines, and amounts paid in settlement, actually and reasonably
incurred by him in connection with the action, suit, or proceeding, if he
acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the Trust, and, with respect to any criminal
action or proceeding, had no reasonable cause to believe his conduct was
unlawful. The termination of any action, suit or proceeding by judgment,
order, settlement, conviction, or upon a plea of nolo contendere or its
equivalent, shall not, of itself, create a presumption that the person did
not act in good faith and in a manner which he reasonably believed to be in
or not opposed to the best interests of the Trust, and, with respect to any
criminal action or proceeding, had reasonable cause to believe that his
conduct was unlawful.

   (b) The Trust shall indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action
or suit by or on behalf of the Trust to obtain a judgment or decree in its
favor by reason of the fact that he is or was a Trustee, officer, employee,
or agent of the Trust. The indemnification shall be against expenses,
including attorneys' fees actually and reasonably incurred by him in
connection with the defense or settlement of the action or suit, if he acted
in good faith and in a manner he reasonably believed to be in or not opposed
to the best interests of the Trust; except that no indemnification shall be
made in respect of any claim, issue, or matter as to which the person has
been adjudged to be liable for negligence or misconduct in the performance of
his duty to the Trust, except to the extent that the court in which the
action or suit was brought, or a court of equity in the county in which the
Trust has its principal office, determines upon application that, despite the
adjudication of liability but in view of all circumstances of the case, the
person is fairly and reasonably entitled to indemnity for those expenses
which the court shall deem proper, provided such Trustee, officer, employee
or agent is not adjudged to be liable by reason of his willful misfeasance,
bad faith, gross negligence or reckless disregard of the duties involved in
the conduct of his office.

   (c) To the extent that a Trustee, officer, employee, or agent of the Trust
has been successful on the merits or otherwise in defense of any action, suit
or proceeding referred to in subsection (a) or (b) or in defense of any
claim, issue or matter therein, he shall be indemnified against expenses,
including attorneys' fees, actually and reasonably incurred by him in
connection therewith.

   (d) (1) Unless a court orders otherwise, any indemnification under
subsections (a) or (b) of this section may be made by the Trust only as
authorized in the specific case after a determination that indemnification of
the Trustee, officer, employee, or agent is proper in the circumstances
because he has met the applicable standard of conduct set forth in
subsections (a) or (b).

    (2) The determination shall be made:

      (i) By the Trustees, by a majority vote of a quorum which consists of
    Trustees who were not parties to the action, suit or proceeding; or

      (ii) If the required quorum is not obtainable, or if a quorum of
    disinterested Trustees so directs, by independent legal counsel in a
    written opinion; or

      (iii) By the Shareholders.

    (3) Notwithstanding any provision of this Section 4.8, no person shall be
entitled to indemnification for any liability, whether or not there is an
adjudication of liability, arising by reason of willful misfeasance, bad
faith, gross negligence, or reckless disregard of duties as described in
Section 17(h) and (i) of the Investment Company Act of 1940 ("disabling
conduct"). A person shall be deemed not liable by reason of disabling
conduct if, either:

      (i) a final decision on the merits is made by a court or other body
    before whom the proceeding was brought that the person to be indemnified
    ("indemnitee") was not liable by reason of disabling conduct; or

      (ii) in the absence of such a decision, a reasonable determination,
    based upon a review of the facts, that the indemnitee was not liable by
    reason of disabling conduct, is made by either--

                                4
<PAGE>
          (A) a majority of a quorum of Trustees who are neither "interested
         persons" of the Trust, as defined in Section 2(a)(19) of the
         Investment Company Act of 1940, nor parties to the action, suit or
         proceeding, or

          (B) an independent legal counsel in a written opinion.

   (e) Expenses, including attorneys' fees, incurred by a Trustee, officer,
employee or agent of the Trust in defending a civil or criminal action, suit
or proceeding may be paid by the Trust in advance of the final disposition
thereof if:

    (1) authorized in the specific case by the Trustees; and

    (2) the Trust receives an undertaking by or on behalf of the Trustee,
   officer, employee or agent of the Trust to repay the advance if it is not
   ultimately determined that such person is entitled to be indemnified by
   the Trust; and

    (3) either, (i) such person provides a security for his undertaking, or

      (ii) the Trust is insured against losses by reason of any lawful
    advances, or

     (iii) a determination, based on a review of readily available facts,
    that there is reason to believe that such person ultimately will be found
    entitled to indemnification, is made by either--

        (A) a majority of a quorum which consists of Trustees who are neither
       "interested persons" of the Trust, as defined in Section 2(a)(19) of
       the 1940 Act, nor parties to the action, suit or proceeding, or

        (B) an independent legal counsel in a written opinion.

   (f) The indemnification provided by this Section shall not be deemed
exclusive of any other rights to which a person may be entitled under any
by-law, agreement, vote of Shareholders or disinterested Trustees or
otherwise, both as to action in his official capacity and as to action in
another capacity while holding the office, and shall continue as to a person
who has ceased to be a Trustee, officer, employee, or agent and inure to the
benefit of the heirs, executors and administrators of such person; provided
that no person may satisfy any right of indemnity or reimbursement granted
herein or to which he may be otherwise entitled except out of the property of
the Trust, and no Shareholder shall be personally liable with respect to any
claim for indemnity or reimbursement or otherwise.

   (g) The Trust may purchase and maintain insurance on behalf of any person
who is or was a Trustee, officer, employee, or agent of the Trust, against
any liability asserted against him and incurred by him in any such capacity,
or arising out of his status as such. However, in no event will the Trust
purchase insurance to indemnify any officer or Trustee against liability for
any act for which the Trust itself is not permitted to indemnify him.

   (h) Nothing contained in this Section shall be construed to protect any
Trustee or officer of the Trust against any liability to the Trust or to its
security holders to which he would otherwise be subject by reason of willful
misfeasance, bad faith, gross negligence or reckless disregard of the duties
involved in the conduct of his office.

                                  ARTICLE V
                                  COMMITTEES

   SECTION 5.1. EXECUTIVE AND OTHER COMMITTEES. The Trustees, by resolution
adopted by a majority of the Trustees, may designate an Executive Committee
and/or committees, each committee to consist of two (2) or more of the
Trustees of the Trust and may delegate to such committees, in the intervals
between meetings of the Trustees, any or all of the powers of the Trustees in
the management of the business and affairs of the Trust. In the absence of
any member of any such committee, the members thereof present at any meeting,
whether or not they constitute a quorum, may appoint a Trustee to act in
place of such absent member. Each such committee shall keep a record of its
proceedings.

                                5
<PAGE>
   The Executive Committee and any other committee shall fix its own rules or
procedure, but the presence of at least fifty percent (50%) of the members of
the whole committee shall in each case be necessary to constitute a quorum of
the committee and the affirmative vote of the majority of the members of the
committee present at the meeting shall be necessary to take action.

   All actions of the Executive Committee shall be reported to the Trustees
at the meeting thereof next succeeding to the taking of such action.

   SECTION 5.2. ADVISORY COMMITTEE. The Trustees may appoint an advisory
committee which shall be composed of persons who do not serve the Trust in
any other capacity and which shall have advisory functions with respect to
the investments of the Trust but which shall have no power to determine that
any security or other investment shall be purchased, sold or otherwise
disposed of by the Trust. The number of persons constituting any such
advisory committee shall be determined from time to time by the Trustees. The
members of any such advisory committee may receive compensation for their
services and may be allowed such fees and expenses for the attendance at
meetings as the Trustees may from time to time determine to be appropriate.

   SECTION 5.3. COMMITTEE ACTION WITHOUT MEETING. The provisions of these
By-Laws covering notices and meetings to the contrary notwithstanding, and
except as required by law, any action required or permitted to be taken at
any meeting of any Committee of the Trustees appointed pursuant to Section
5.1 of these By-Laws may be taken without a meeting if a consent in writing
setting forth the action shall be signed by all members of the Committee
entitled to vote upon the action and such written consent is filed with the

   Subject to any applicable provisions of law and the Declaration, dividends
and distributions upon the Shares may be declared at such intervals as the

<PAGE>
   Inasmuch as the computation of net income and net profits from the sales
of securities or other properties for federal income tax purposes may vary
from the computation thereof on the records of the Trust, the Trustees shall
have power, in their discretion, to distribute as income dividends and as
capital gain distributions, respectively, amounts sufficient to enable the

                                 ARTICLE VIII

   SECTION 8.1. CERTIFICATES OF SHARES. Certificates for Shares of each
series or class of Shares shall be in such form and of such design as the
Trustees shall approve, subject to the right of the Trustees to change such
form and design at any time or from time to time, and shall be entered in the
records of the Trust as they are issued. Each such certificate shall bear a
distinguishing number; shall exhibit the holder's name and certify the number
of full Shares owned by such holder; shall be signed by or in the name of the
Trust by the Chairman, the President, or a Vice President, and countersigned
by the Secretary or an Assistant Secretary or the Treasurer and an Assistant
Treasurer of the Trust; shall be sealed with the seal; and shall contain such

may be facsimile, printed or engraved. The Trust may, at its option,
determine not to issue a certificate or certificates to evidence Shares owned
of record by any Shareholder.

   In case any officer or officers who shall have signed, or whose facsimile
signature or signatures shall appear on, any such certificate or certificates
shall cease to be such officer or officers of the Trust, whether because of
death, resignation or otherwise, before such certificate or certificates
shall have been delivered by the Trust, such certificate or certificates
shall, nevertheless, be adopted by the Trust and be issued and delivered as
though the person or persons who signed such certificate or certificates or
whose facsimile signature or signatures shall appear therein had not ceased
to be such officer or officers of the Trust.

   No certificate shall be issued for any share until such share is fully
paid.

   SECTION 8.2. LOST, STOLEN, DESTROYED AND MUTILATED CERTIFICATES. The
Trustees may direct a new certificate or certificates to be issued in place
of any certificate or certificates theretofore issued by the Trust alleged to
have been lost, stolen or destroyed, upon satisfactory proof of such loss,
theft, or destruction; and the Trustees may, in their discretion, require the
owner of the lost, stolen or destroyed certificate, or his legal
representative, to give to the Trust and to such Registrar, Transfer Agent
and/or Transfer Clerk as may be authorized or required to countersign such
new certificate or certificates, a bond in such sum and of such type as they
may direct, and with such surety or sureties, as they may direct, as
indemnity against any claim that may be against them or any of them on
account of or in connection with the alleged loss, theft or destruction of
any such certificate.

                                  ARTICLE IX

if any, as may be contained in these By-Laws and the 1940 Act:

     (1) to receive and hold the securities owned by the Trust and deliver the
    same upon written or electronically transmitted order;

     (2) to receive and receipt for any moneys due to the Trust and deposit
    the same in its own banking department or elsewhere as the Trustees may
    direct;

     (3) to disburse such funds upon orders or vouchers;

                                8
<PAGE>
all upon such basis of compensation as may be agreed upon between the
Trustees and the custodian. If so directed by a Majority Shareholder Vote,
the custodian shall deliver and pay over all property of the Trust held by it
as specified in such vote.

   The Trustees may also authorize the custodian to employ one or more
sub-custodians from time to time to perform such of the acts and services of
the custodian and upon such terms and conditions as may be agreed upon
between the custodian and such sub-custodian and approved by the Trustees.

   SECTION 9.2. CENTRAL CERTIFICATE SYSTEM. Subject to such rules,
regulations and orders as the Commission may adopt, the Trustees may direct
the custodian to deposit all or any part of the securities owned by the Trust
in a system for the central handling of securities established by a national
securities exchange or a national securities association registered with the
Commission under the Securities Exchange Act of 1934, or such other person as
may be permitted by the Commission, or otherwise in accordance with the 1940
Act, pursuant to which system all securities of any particular class or
series of any issuer deposited within the system are treated as fungible and
may be transferred or pledged by bookkeeping entry without physical delivery
of such securities, provided that all such deposits shall be subject to
withdrawal only upon the order of the Trust.

                                  ARTICLE X
                               WAIVER OF NOTICE

   Whenever any notice of the time, place or purpose of any meeting of
Shareholders, Trustees, or of any committee is required to be given in
accordance with law or under the provisions of the Declaration or these
By-Laws, a waiver thereof in writing, signed by the person or persons
entitled to such notice and filed with the records of the meeting, whether
before or after the holding thereof, or actual attendance at the meeting of
shareholders, Trustees or committee, as the case may be, in person, shall be
deemed equivalent to the giving of such notice to such person.

record date for the purpose of determining the Shareholders entitled to (i)
receive notice of, or to vote at, any meeting of Shareholders, or (ii)
receive payment of any dividend or the allotment of any rights, or in order
to make a determination of Shareholders for any other proper purpose. The
record date, in any case, shall not be more than one hundred eighty (180)
days, and in the case of a meeting of Shareholders not less than ten (10)
days, prior to the date on which such meeting is to be held or the date on
which such other particular action requiring determination of Shareholders is
to be taken, as the case may be. In the case of a meeting of Shareholders,
the meeting date set forth in the notice to Shareholders accompanying the
proxy statement shall be the date used for purposes of calculating the 180
day or 10 day period, and any adjourned meeting may be reconvened without a
change in record date. In lieu of fixing a record date, the Trustees may
provide that the transfer books shall be closed for a stated period but not
to exceed, in any case, twenty (20) days. If the transfer books are closed
for the purpose of determining Shareholders entitled to notice of a vote at a
meeting of Shareholders, such books shall be closed for at least ten (10)
days immediately preceding the meeting.

   SECTION 11.3. SEAL. The Trustees shall adopt a seal, which shall be in
such form and shall have such inscription thereon as the Trustees may from
time to time provide. The seal of the Trust may be affixed to any document,
and the seal and its attestation may be lithographed, engraved or otherwise
printed on any document with the same force and effect as if it had been
imprinted and attested manually in the same manner and with the same effect
as if done by a Massachusetts business corporation under Massachusetts law.

to time.

the payment of money of the Trust, and all notes or other evidences of
indebtedness issued in the name of the Trust, shall be signed by such officer
or officers or such other person or persons as the Trustees may from time to
time designate, or as may be specified in or pursuant to the agreement
between the Trust and the bank or trust company appointed as Custodian of the
securities and funds of the Trust.

                                 ARTICLE XII
                     COMPLIANCE WITH FEDERAL REGULATIONS

   The Trustees are hereby empowered to take such action as they may deem to
be necessary, desirable or appropriate so that the Trust is or shall be in
compliance with any federal or state statute, rule or regulation with which
compliance by the Trust is required.

                                 ARTICLE XIII
                                  AMENDMENTS

   These By-Laws may be amended, altered, or repealed, or new By-Laws may be
adopted, (a) by a Majority Shareholder Vote, or (b) by the Trustees;
provided, however, that no By-Law may be amended, adopted or repealed by the
Trustees if such amendment, adoption or repeal requires, pursuant to law, the
Declaration, or these By-Laws, a vote of the Shareholders. The Trustees shall
in no event adopt By-Laws which are in conflict with the Declaration, and any
apparent inconsistency shall be construed in favor of the related provisions
in the Declaration.

                                 ARTICLE XIV
                             DECLARATION OF TRUST

   The Declaration of Trust establishing TCW/DW Balanced Fund, dated March 1,
1993, a copy of which is on file in the office of the Secretary of the
Commonwealth of Massachusetts, provides that the name TCW/DW Balanced Fund
refers to the Trustees under the Declaration collectively as Trustees, but
not as individuals or personally; and no Trustee, Shareholder, officer,
employee or agent of TCW/DW Balanced Fund shall be held to any personal
liability, nor shall resort be had to their private property for the
