               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.")

The                 The Fund is organized as a Trust, commonly known as a Massachusetts business trust, and is an open-end,

                    charge, and concurrent investments in Class D shares of the Fund and other Dean Witter Funds that are multiple
                    class funds, will be aggregated. The minimum subsequent investment is $100 (see page 21).
- ------------------------------------------------------------------------------------------------------------------------------------
Investment          The primary investment objective of the Fund is to provide a high level of current income. As a secondary

- ------------------------------------------------------------------------------------------------------------------------------------
Investment          Dean Witter InterCapital Inc. ("InterCapital"), the Investment Manager of the Fund, and its wholly-owned
Manager             subsidiary, Dean Witter Services Company Inc., serve in various investment management, advisory, management and

                    billion at December 31, 1997 (see page 9).
- ------------------------------------------------------------------------------------------------------------------------------------
Management          The Investment Manager receives a monthly fee at the annual rate of 0.75% of the Fund's daily net assets, scaled
Fee                 down at various asset levels to 0.30% of the Fund's daily net assets on assets in excess of $1 billion (see page
                    9).
- ------------------------------------------------------------------------------------------------------------------------------------
Distributor and     Dean Witter Distributors Inc. (the "Distributor"). The Fund has adopted a distribution plan pursuant to Rule
Distribution Fee    12b-1 under the Investment Company Act (the "12b-1 Plan") with respect to the distribution fees paid by the
                    Class A, Class B and Class C shares of the Fund to the Distributor. 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 0.20% of the average daily net assets
                    of Class B and 0.25% of the average daily net assets of Class C are currently each characterized as a service
                    fee within the meaning of the National Association of Securities Dealers, Inc. guidelines. The remaining portion
                    of the 12b-1 fee, if any, is characterized as an asset-based sales charge (see pages 21 and 29).
- ------------------------------------------------------------------------------------------------------------------------------------
Alternative         Four classes of shares are offered:
Purchase
Arrangements        - Class A shares are offered with a front-end sales charge, starting at 4.25% 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 21, 24 and 29).

<TABLE>
<S>                 <C>
                    - 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 0.85% of the lesser of: (a) the average daily net sales of
                    the Fund's Class B shares or (b) the average daily net assets of Class B. All shares of the Fund held prior to
                    July 28, 1997 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 convert to Class A shares approximately ten years after the
                    date of the original purchase (see pages 21, 26 and 29).
                    - 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 0.85% of average daily net assets of the Class (see pages 21 and 29).
                    - Class D shares are offered only to investors meeting an initial investment minimum of $5 million ($25 million
                    for certain qualified plans) 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 21 and 29).
- ------------------------------------------------------------------------------------------------------------------------------------
Dividends and       Dividends from net investment income are declared and paid monthly. Capital gains, if any, are paid at least
Capital Gains       annually. The Fund may, however, determine to retain all or part of any net long-term capital gains in any year
Distributions       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 32 and 36).
- ------------------------------------------------------------------------------------------------------------------------------------
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 36).
- ------------------------------------------------------------------------------------------------------------------------------------
Special             The net asset value of the Fund's shares will fluctuate with changes in the market value of its portfolio
Risk                securities. The Fund is a non-diversified investment company and, as such, is not subject to the diversification
Considerations      requirements of the Investment Company Act of 1940, as amended (see page 10). In addition, it should be
                    recognized that the foreign securities and markets in which the Fund will invest pose different and possibly
                    greater risks than those customarily associated with domestic securities and their markets. Moreover, investors
                    should consider other risks associated with a portfolio of international securities, including fluctuations in
                    foreign currency exchange rates (i.e., if a substantial portion of the Fund's assets are denominated in foreign
                    currencies which decrease in value with respect to the U.S. dollar, the value of the investor's shares and the
                    distributions made on those shares will, likewise, decrease in value), foreign securities exchange controls and
                    foreign tax rates, as well as investments in forward currency contracts, options and futures contracts (see
                    pages 12-19).

(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 0.20% OF THE AVERAGE DAILY NET ASSETS OF CLASS B AND
    0.25% OF THE AVERAGE DAILY NET ASSETS OF CLASS C 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 0.85% DISTRIBUTION FEE (SEE "PURCHASE OF FUND
    SHARES--ALTERNATIVE PURCHASE ARRANGEMENTS").
   
(7) THERE WERE NO OUTSTANDING SHARES OF CLASS A, CLASS C 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," "Purchase of Fund Shares--Plan of Distribution"
and "Redemptions and Repurchases."
 
    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
- --------------------------------------------------------------------------------
 
    Dean Witter World Wide Income Trust (the "Fund") is an open-end,
non-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 October 14, 1988.
 
    Dean Witter InterCapital Inc. ("InterCapital" or (the "Investment Manager"),
whose address is Two World Trade Center, New York, New York 10048, is the Fund's
Investment Manager. The Investment Manager, which was incorporated in July,
1992, 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.
 
   
    InterCapital and its wholly-owned subsidiary, Dean Witter Services Company
Inc., serve in various investment management, advisory, management and
administrative capacities to 103 investment companies, 29 of which are listed on
the New York Stock Exchange, with combined total assets of approximately $98.9
billion as of December 31, 1997. The Investment Manager also manages portfolios
of pension plans, other institutions and individuals which aggregated
approximately $4 billion at such date.
    
 
    The Fund has retained the Investment Manager to provide administrative
services, manage its business affairs and manage the investment of the Fund's
assets, including the placing of orders for the purchase and sale of portfolio
securities. InterCapital has retained Dean Witter Services Company Inc. to
perform the aforementioned administrative services for the Fund.
 
    The Fund's Trustees review the various services provided by or under the
direction of the Investment Manager 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 Investment Manager, the Fund pays
the Investment Manager monthly compensation calculated daily at an annual rate
of 0.75% of the daily net assets of the Fund up to $250 million, scaled down at
various asset levels to 0.30% of the daily net assets of the Fund exceeding $1
billion. For the fiscal year ended October 31, 1997, the Fund accrued total
compensation to the Investment Manager amounting to 0.75% of the Fund's average
daily net assets and the total expenses of Class B amounted to 2.02% of the
average daily net assets of Class B. Shares of Class A, Class C and Class D were
first issued on July 28, 1997. The expenses of the Fund include: the fee of the
Investment Manager; 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 Investment Manager under its Investment
Management Agreement with the Fund.
    
 
INVESTMENT OBJECTIVES AND POLICIES
- --------------------------------------------------------------------------------
 
    The primary investment objective of the Fund is to provide a high level of
current income. As a secondary objective, the Fund will seek appreciation in the
value of its assets. The Fund will attempt to achieve its investment objectives
by investing primarily in a portfolio of fixed-income securities issued by
foreign and U.S. corporations or issued or guaranteed by foreign governments,
government
 
                                       9
<PAGE>
agencies or government subdivisions, supranational organizations (or any
subdivision thereof) and the U.S. Government, its agencies and
instrumentalities. There can be no assurance that the Fund will achieve its
objectives. The investment objectives are fundamental policies of the Fund and,
as such, may not be changed without the approval of the shareholders of the
Fund.
 
    The Fund may invest in securities issued by government entities or
corporations of any single nation and which are denominated in any single
currency. The Investment Manager will, however, actively allocate the Fund's
investments among various geographic regions, nations, currencies and
corporations or governmental entities in its attempt to maximize the dividends
paid on the Fund's shares and, if possible, the appreciation of their value. In
addition, it is the Fund's policy that, during normal market conditions, its
assets will be comprised of investments in the securities of issuers located in
at least three separate nations (which may include the United States). The
Investment Manager will consider such factors as the yield of individual
securities, the anticipated appreciation of such securities, the state of the
economies of the countries in which the investments are made, the levels of
inflation existing in such countries, the liquidity and financial soundness of
the markets in which such securities trade, the levels of inflation existing
within the relevant country and the current and anticipated relationships of
such countries' currencies to the U.S. dollar. The currency in which the Fund's
securities will be principally denominated will be a function of these factors
in that, at any given time, the Investment Manager may determine, after review
of these factors, that the fixed-income securities in a given country are
superior to the fixed-income securities in a different country, and,
accordingly, increase the proportion of the Fund's assets denominated in the
currency of the country with the superior investment climate.
 
    It is anticipated that the securities held by the Fund in its portfolio will
be denominated, principally, in the following currencies: the United States
dollar, Australian dollar, New Zealand dollar, German mark, Japanese yen, French
franc, British pound, Canadian dollar, Mexican peso, Swiss franc, Dutch guilder,
Belgian franc, Swedish kronor, Italian lira, Finnish markka and European
Currency Unit (a weighted composite of the currencies of member states of the
European Monetary System). Securities of issuers within a given country may be
denominated in the currency of a different country.
 
    The U.S. Government securities in which the Fund may invest include U.S.
Treasury bonds, notes and bills, which are direct obligations of the U.S.
Government as well as in securities issued or guaranteed by agencies and
instrumentalities of the U.S. Government. Some of the securities of such
agencies and instrumentalities are backed by the full faith and credit of the
U.S. (e.g., the Government National Mortgage Association), while others are not
backed by the full faith and credit of the U.S. but are backed by the credit of
the issuing agency or instrumentality (e.g., the Federal Home Loan Bank) or are
backed by an existing line of credit with the U.S. Treasury from which its
issuing agency or instrumentality may borrow (e.g., the Federal National
Mortgage Association).
 
    The Fund may invest in fixed-income securities issued or guaranteed by
supranational organizations. Such organizations are entities designated or
supported by a government or government entity to promote economic development,
and include, among others, the Asian Development Bank, the European Coal and
Steel Community, the European Economic Community and the World Bank. These
organizations do not have taxing authority and are dependent upon their members
for payments of interest and principal. Each supranational entity's lending
activities are limited to a percentage of its total capital (including "callable
capital" contributed by members at the entity's call), reserves and net income.
Securities issued by supranational organizations may be denominated in U.S.
dollars or in foreign currencies.
 
                                       10
<PAGE>
    In seeking to achieve its objectives, the Fund will normally invest at least
65% of its assets in fixed-income securities issued or guaranteed by the U.S.
Government, its agencies and instrumentalities or fixed-income securities issued
by U.S. corporations, foreign governments, foreign corporations or other
entities which have been rated within the four highest categories as determined
by Moody's Investors Service, Inc. ("Moody's") (Aaa, Aa, A or Baa) or Standard &
Poor's Corporation ("S&P") (AAA, AA, A or BBB), or which are unrated by such
rating agencies but which are deemed to be of comparable quality by the
Investment Manager. The ratings of fixed-income securities by Moody's and S&P
are a generally accepted barometer of credit risk. Fixed-income securities rated
Baa by Moody's have certain speculative characteristics. A description of S&P
and Moody's ratings is contained in the Statement of Additional Information.
 
    The types of fixed-income securities invested in by the Fund include
straight debt obligations of varying maturities, such as bonds, notes, bills,
debentures, equipment lease and trust certificates, conditional sales contracts,
commercial paper, commercial bank obligations, obligations of savings
institutions, bankers' acceptances, Eurodollar certificates of deposit and fixed
and adjustable rate preferred stocks.
 
    The Fund may invest without limitation in notes and commercial paper, the
principal amount of which is indexed to certain specific foreign currency
exchange rates. Indexed notes and commercial paper typically provide that their
principal amount is adjusted upwards or downwards (but not below zero) at
maturity to reflect fluctuations in the exchange rate between two currencies
during the period the obligation is outstanding, depending on the terms of the
specific security. In selecting the two currencies, the Investment Manager will
consider the correlation and relative yields of various currencies. The Fund
will purchase an indexed obligation using the currency in which it is
denominated and, at maturity, will receive interest and principal payments
thereon in that currency. The amount of principal payable by the issuer at
maturity, however, will vary (i.e., increase or decrease) in response to the
change (if any) in the exchange rates between the two specified currencies
during the period from the date the instrument is issued to its maturity date.
The potential for realizing gains as a result of changes in foreign currency
exchange rates may enable the Fund to hedge the currency in which the obligation
is denominated (or to effect cross-hedges against other currencies) against a
decline in the U.S. dollar value of investments denominated in foreign
currencies, while providing an attractive money market rate of return. The Fund
will purchase such indexed obligations to generate current income or for hedging
purposes and will not speculate in such obligations.
 
    Under normal conditions, a percentage of the short-term investments in the
Fund's portfolio may be money market securities. Money market securities include
short-term obligations issued or guaranteed by the U.S. Government or foreign
governments or issued by such governments' respective agencies and
instrumentalities, bank money market instruments including certificates of
deposit, bankers' acceptances, time deposits and deposit notes and certain other
short-term obligations such as short-term commercial paper. With respect to bank
money instruments, the obligations may be issued by U.S. or foreign depository
institutions, foreign branches or subsidiaries of U.S. depository institutions
("Eurodollar" obligations), U.S. branches or subsidiaries of foreign depository
institutions ("Yankeedollar" obligations) or foreign branches or subsidiaries of
foreign depository institutions. Eurodollar and Yankeedollar obligations and
obligations of branches or subsidiaries of foreign depository institutions may
be general obligations of the parent bank or may be limited to the issuing
branch or subsidiary by the terms of the specific obligations or by government
regulation.
 
    In addition, the Fund may invest in fixed-income securities which are
convertible into common stock, such as convertible debentures and convertible
preferred stock, and fixed-income securities to which are attached equity
features such as
 
                                       11
<PAGE>
shares of common stock, warrants for the purchase of common stock,
participations based on revenues, sales or profits and other conversion and/or
exchange rights.
 
    The Fund may also invest in securities of foreign issuers in the form of
American Depository Receipts (ADRs), European Depository Receipts (EDRs) or
other similar securities convertible into securities of foreign issuers. These
securities may not necessarily be denominated in the same currency as the
securities into which they may be converted. ADRs are receipts typically issued
by a United States bank or trust company evidencing ownership of the underlying
securities. EDRs are European receipts evidencing a similar arrangement.
Generally, ADRs, in registered form, are designed for use in the United States
securities markets and EDRs, in bearer form, are designed for use in European
securities markets.
 
    There may be periods during which, in the opinion of the Investment Manager,
market conditions warrant reduction of some or all of the Fund's securities
holdings. During such periods, the Fund may adopt a temporary "defensive"
posture in which greater than 35% of its assets are invested in cash or money
market instruments. Under such circumstances, the money market instruments in
which the Fund may invest are securities issued or guaranteed by the U.S.
Government; U.S. bank obligations; Eurodollar certificates of deposit;
obligations of American savings institutions; fully insured certificates of
deposit; and commercial paper of U.S. issuers rated within the two highest
grades by Moody's or S&P or, if not rated, are issued by a company having an
outstanding debt issue rated at least AA by S&P or Aa by Moody's.
 
RISK CONSIDERATIONS
 
    The net asset value of the Fund's shares will fluctuate with changes in the
market value of its portfolio securities. The market value of the Fund's
portfolio securities will increase or decrease due to a variety of economic,
market or political factors which cannot be predicted. The Fund's yield will
also vary based on the yield of the Fund's portfolio 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. 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.
 
    The Fund may also purchase fixed-income securities which are issued by U.S.
issuers and which are denominated in U.S. dollars but which return principal to
investors in amounts which are tied to the exchange rate between the U.S. dollar
and a foreign currency. The payment of interest on such securities is generally
made at a fixed U.S. dollar rate.
 
    NON-DIVERSIFIED STATUS.  The Fund is a non-diversified investment company
and, as such, is not subject to the diversification requirements of the
Investment Company Act of 1940, as amended (the "Act"). As a non-diversified
investment company, the Fund may invest a greater portion of its assets in the
securities of a single issuer and thus is subject to greater exposure to risks
such as a decline in the credit rating of that issuer. However, the Fund
anticipates that it will qualify as a regulated investment company under the
federal income tax laws and, if so qualified, will be subject to the applicable
diversification requirements of the Internal Revenue Code, as amended (the
"Code"). As a regulated investment company under the Code, the Fund may not, as
of the end of any of its fiscal quarters, have invested more than 25% of its
total assets in the securities of any one issuer (including a foreign
government), or as to 50% of its total assets, have invested more than 5% of its
total assets in the securities of a single issuer.
 
                                       12
<PAGE>
    FOREIGN SECURITIES.  Investors should carefully consider the risks of
investing in securities of foreign issuers and securities denominated in
non-U.S. currencies. Fluctuations in the relative rates of exchange between the
currencies of different nations may 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 yield on such assets and the net asset value
of a share of the Fund as well as the amount of the Fund's distributions. For
example, if a substantial portion of the Fund's assets are denominated in
Japanese yen and the relative exchange rate of the yen falls with respect to the
U.S. dollar (i.e., a yen is worth a smaller fraction of a dollar than it had
been) then the Fund will be receiving a lesser amount of interest on its
fixed-income securities denominated in yen (when converted into U.S. dollars)
and when the Fund's assets are valued for purposes of determining the net asset
value per share of the Fund, the net assets of the Fund reflected by the
yen-denominated securities will have declined in U.S. dollar value and the net
asset value of the Fund (always stated in U.S. dollars) may have also declined.
 
    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. The foreign currency transactions of
the Fund will be conducted on a spot basis or through forward contracts or
futures contracts (see below). The Fund may incur certain costs in connection
with these currency transactions.
 
    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 generally subject to
uniform accounting, auditing and financial 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 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.
                                  ------------
 
    To hedge against adverse price movements in the securities held in its
portfolio and the currencies in which they are denominated (as well as in the
securities it might wish to purchase and their denominated currencies) the Fund
may engage in transactions in forward foreign currency contracts, options on
securities and currencies, and futures contracts and options on futures
contracts on securities, currencies and indexes. The Fund may also write options
on securities and currencies to assist it in meeting its objective of providing
a high level of current income. A discussion of these transactions follows and
is supplemented by further disclosure in the Statement of Additional
Information.
 
                                       13
<PAGE>
    FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS. A forward foreign currency
exchange contract ("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. 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 Fund's Investment Manager believes
that the currency of a particular foreign country may suffer a substantial
decline against the U.S. dollar or some other foreign currency, it 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 portfolio securities (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.
The Investment Manager will select this method of hedging, called
"cross-hedging," when it determines that the foreign currency in which the
portfolio securities are denominated have insufficient liquidity or are trading
at a discount as compared with some other foreign currency with which it tends
to move in tandem.
 
    In addition, when the Fund's Investment Manager 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, it 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.
 
    Lastly, the Fund is permitted to enter into forward contracts with respect
to currencies in which certain of its portfolio securities are denominated and
on which options have been written (see "Options and Futures Transactions").
 
    In all of the above circumstances, if the currency in which the Fund's
portfolio securities (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 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 Investment Manager.
 
                                       14
<PAGE>
    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. To the extent that the Fund enters into forward foreign
currency contracts to hedge against a decline in the value of portfolio holdings
denominated in a particular foreign currency resulting from currency
fluctuations, there is a risk that the Fund may nevertheless realize a gain or
loss as a result of currency fluctuations after such portfolio holdings are sold
if the Fund is unable to enter into an "offsetting" forward foreign currency
contract with the same party or another party. The Fund may be limited in its
ability to enter into hedging transactions involving forward contracts by the
Code requirements relating to qualification as a regulated investment company
(see "Dividends, Distributions and Taxes").
 
OPTIONS AND FUTURES TRANSACTIONS
 
    The Fund may purchase and sell (write) call and put options on U.S. Treasury
notes, bonds and bills, on various foreign currencies and on equity securities
which are listed on several U.S. and foreign securities exchanges and are
written in over-the-counter transactions ("OTC options"). Listed options are
issued or guaranteed by the exchange on which they trade or by a clearing
corporation such as the Options Clearing Corporation ("OCC"). Ownership of a
listed call option gives the Fund the right to buy from the OCC (in the U.S.) or
other clearing corporation or exchange, the underlying security or currency
covered by the option at the stated exercise price (the price per unit of the
underlying security or currency) by filing an exercise notice prior to the
expiration date of the option. Ownership of a listed put option would give the
Fund the right to sell the underlying security or currency to the OCC (in the
U.S.) or other clearing corporation or exchange at the stated exercise price.
OTC options are purchased from or sold (written) to dealers or financial
institutions which have entered into direct agreements with the Fund. With
respect to 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.
 
    COVERED CALL WRITING.  The Fund is permitted to write covered call options
on portfolio securities which are denominated in either U.S. dollars or foreign
currencies, without limit, in order to aid it in achieving its investment
objectives and to close out long call option positions. As a writer of a call
option, the Fund has the obligation, upon notice of exercise of the option, to
deliver the security or amount of currency underlying the option (certain listed
and OTC call options written by the Fund will be exercisable by the purchaser
only on a specific date).
 
    COVERED PUT WRITING.  As a writer of covered put options, the Fund incurs an
obligation to buy the security (or currency) 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). The Fund will write put options for three purposes: (1) to receive the
premiums paid by purchasers; (2) when the Investment Manager wishes to purchase
the security underlying the option (or a security denominated in the currency
underlying the option) at a price lower than its current market price, in which
case it will write the covered put at an exercise price reflecting the lower
purchase price sought; and (3) to close out a long put option position. The
aggregate value of the obligations underlying the puts determined as of the date
the options are sold will not exceed 50% of the Fund's net assets.
 
    PURCHASING CALL AND PUT OPTIONS.  The Fund may purchase listed and OTC call
and put options in amounts equalling up to 5% of its total assets. The Fund may
purchase call options to close out a written call position or to protect against
an increase in the price of a security it anticipates purchasing or, in the case
of call options on a foreign currency, to hedge against an adverse exchange rate
change of the currency in which the security it anticipates
 
                                       15
<PAGE>
purchasing is denominated vis-a-vis the currency in which the exercise price is
denominated. The Fund may purchase put options on securities which it holds in
its portfolio only to protect itself against a decline in the value of the
security. Similarly, the Fund may purchase put options on currencies in which
securities which it holds are denominated only to protect itself against a
decline in value of such currency vis-a-vis the currency in which the exercise
price is denominated. There are no other limits on the Fund's ability to
purchase call and put options.
 
    FUTURES CONTRACTS.  The Fund may purchase and sell futures contracts that
are currently traded, or may in the future be traded, on U.S. and foreign
commodity exchanges on such underlying fixed-income securities as U.S. Treasury
bonds, notes, and bills and/or any foreign government fixed-income security
("interest rate" futures), on various currencies ("currency" futures) and on
such indexes of U.S. or foreign fixed-income securities as may exist or come
into being, such as the Moody's Investment-Grade Corporate Bond 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 for the
purpose of hedging the value of its fixed-income portfolio securities (or
anticipated portfolio securities) against changes in prevailing interest rates.
The Fund will purchase or sell index futures contracts for the purpose of
hedging its fixed-income portfolio (or anticipated portfolio) against changes in
their prices. The Fund will purchase or sell currency futures on currencies in
which its portfolio securities (or anticipated portfolio securities) are
denominated for the purposes of hedging against anticipated changes in currency
exchange rates. In addition to the above, interest rate, index and currency
futures will be bought or sold in order to close out a short or long position
maintained by the Fund in a corresponding futures contract.
 
    OPTIONS ON FUTURES CONTRACTS.  The Fund may purchase and write call and put
options on futures contracts which are traded on an exchange and enter into
closing transactions with respect to such options to terminate an existing
position. An option on a futures contract gives the purchaser the right (in
return for the premium paid) to assume a position in a futures contract (a long
position if the option is a call and a short position if the option is a put) at
a specified exercise price at any time during the term of the option.
 
    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.
 
    RISKS OF OPTIONS AND FUTURES TRANSACTIONS. The Fund may close out its
position as writer of an option, or as a buyer or seller of a futures contract,
only if a liquid secondary market exists for options or futures contracts of
that series. There is no assurance that such a market will exist, particularly
in the case of OTC options, as such options will generally only be closed out by
entering into a closing purchase transaction with the purchasing dealer.
 
    Exchanges may limit the amount by which the price of many 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.
 
    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 is that
 
                                       16
<PAGE>
the Investment Manager could be incorrect in its expectations as to the
direction or extent of various interest rate or price movements or the time span
within which the movements take place. For example, if the Fund sold futures
contracts for the sale of securities in anticipation of an increase in interest
rates, and then interest rates went down instead, causing bond prices to rise,
the Fund would lose money on the sale.
 
    Another risk which may arise in employing futures contracts to protect
against the price volatility of portfolio securities is that the prices of
securities, currencies and indexes subject to futures contracts (and thereby the
futures contract prices) may correlate imperfectly with the behavior of the U.S.
dollar cash prices of the Fund's portfolio securities and their denominated
currencies. 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 Fund, by entering into transactions in foreign futures and options
markets, will also incur risks similar to those discussed above under the
section entitled "Foreign Securities."
 
OTHER INVESTMENT POLICIES
 
    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 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 those 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
Investment Manager subject to procedures established by the Board of Trustees of
the Fund.
 
    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 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, the
convertible security will 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
 
                                       17
<PAGE>
directly with the price of the underlying equity security.
 
    REVERSE REPURCHASE AGREEMENTS.  The Fund may also use reverse repurchase
agreements 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. Reverse
repurchase agreements 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 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 are
speculative techniques involving leverage, and are considered borrowings by the
Fund.
 
    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. 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.
 
    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.
 
    PRIVATE PLACEMENTS.  The Fund may invest up to 10% of its total assets in
securities which are subject to restrictions on resale because they have not
been registered under the Securities Act of
 
                                       18
<PAGE>
1933, as amended (the "Securities Act"), or which are otherwise not readily
marketable. (Securities eligible for resale pursuant to Rule 144A of 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 Investment Manager,
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 is limited by
the Fund's investment restrictions to 10% of the Fund's total assets. Investing
in Rule 144A securities could have the effect of increasing the level of Fund
illiquidity to the extent the Fund, at a particular time, may be unable to find
qualified institutional buyers interested in purchasing such securities.
 
    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 certain notice provisions described in the Statement of
Additional Information), and are at all times secured by cash or cash
equivalents, which are maintained in a segregated account pursuant to applicable
regulations and that are at least equal to the market value, determined daily,
of the loaned securities. 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, loans of portfolio
securities will only be made to firms deemed by the Investment Manager to be
creditworthy and when the income which can be earned from such loans justifies
the attendant risks.
 
    Except as specifically noted, all investment objectives, policies and
practices discussed above are not fundamental policies of the Fund and, as such,
may be changed without shareholder approval.
 
   
    YEAR 2000.  The investment management services provided to the Fund by the
Investment Manager and the services provided to shareholders by the Distributor
and the Transfer Agent depend on the smooth functioning of their computer
systems. Many computer software systems in use today cannot recognize the year
2000, but revert to 1900 or some other date, due to the manner in which dates
were encoded and calculated. That failure could have a negative impact on the
handling of securities trades, pricing and account services. The Investment
Manager, the Distributor and the Transfer Agent have been actively working on
necessary changes to their own computer systems to prepare for the year 2000 and
expect that their systems will be adapted before that date, but there can be no
assurance that they will be successful, or that interaction with other
non-complying computer systems will not impair their services at that time.
    
 
    For additional risk disclosure, please refer to the discussion of specific
investments under the "Investment Objectives and Policies" section of the
Prospectus and the "Investment Practices and Policies" section of the Statement
of Additional Information.
 
PORTFOLIO MANAGEMENT
 
    The Fund's portfolio is actively managed by its Investment Manager with a
view to achieving the Fund's investment objectives.
 
   
    The Fund is managed within InterCapital's Taxable Fixed-Income Group, which
manages 23 funds
    
 
                                       19
<PAGE>
   
and fund portfolios, with approximately $13.3 billion in assets at December 31,
1997. Rajesh K. Gupta, Senior Vice President of InterCapital, and Peter J.
Seeley, Vice President of InterCapital (since April, 1996), each a member of
InterCapital's Taxable Fixed-Income Group, are the primary portfolio managers of
the Fund. Mr. Gupta and Mr. Seeley have been the Fund's primary portfolio
managers since February, 1998 and December, 1994, respectively. Mr. Gupta has
been managing portfolios consisting of fixed-income securities since June, 1987.
Mr. Seeley has been a portfolio manager with InterCapital since July, 1994,
prior to which time he was a portfolio manager with Nikko Capital Management
(October, 1992-June, 1994). In determining which securities to purchase for the
Fund or hold in the Fund's portfolio, the Investment Manager will rely on
information from various sources, including research, analysis and appraisals of
brokers and dealers, including Dean Witter Reynolds Inc. ("DWR"), Morgan Stanley
& Co. Incorporated and other broker-dealer affiliates of InterCapital, and the
views of others regarding economic developments and interest rate trends, and
the Investment Manager's own analysis of factors it deems relevant.
    
 
    Personnel of the Investment Manager have 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.
 
   
    Securities purchased by the Fund are generally sold by dealers acting as
principal for their own accounts. Orders for transactions in other portfolio
securities and commodities are placed for the Fund with a number of brokers and
dealers, including DWR, Morgan Stanley & Co. Incorporated and other
broker-dealers that are affiliates of InterCapital. The Fund may incur brokerage
commissions on transactions conducted through such affiliates. Pursuant to an
order of the Securities and Exchange Commission, the Fund may effect principal
transactions in certain money market instruments with DWR and Morgan Stanley &
Co. Incorporated.
    
 
   
    The Fund may sell portfolio securities without regard to the length of time
that they have been held, in order to take advantage of new investment
opportunities or yield differentials, or because the Fund desires to preserve
gains or limit losses due to changing economic conditions, interest rate trends,
or the financial condition of the issuer. It is not anticipated that the Fund's
portfolio turnover rate will exceed 300% in any one year. The Fund will incur
underwriting discount costs (on underwritten securities) and brokerage costs
commensurate with its portfolio turnover rate. Short term gains and losses may
result from such portfolio transactions. See "Dividends, Distributions and
Taxes" for a discussion of the tax implications of the Fund's transactions.
    
 
INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------
 
    The investment restrictions listed below are among the restrictions which
have been adopted by the Fund as fundamental policies. 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. 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. Invest 25% or more of the value of its total assets in securities of
issuers in any one industry.
 
                                       20
<PAGE>
   2. 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 shall not apply to any obligation issued
or guaranteed by the United States Government, its agencies or
instrumentalities.
 
   3. Purchase or sell commodities or commodities contracts except that the Fund
may purchase or write interest rate, currency and stock and bond index futures
contracts and related options thereon.
 
   4. Pledge its assets or assign or otherwise encumber them except to secure
permitted borrowings. (For the purpose of this restriction, collateral
arrangements with respect to the writing of options and collateral arrangements
with respect to initial or variation margin for futures are not deemed to be
pledges of assets.)
 
   5. Purchase securities on margin (but the Fund may obtain short-term loans as
are necessary for the clearance of transactions). The deposit or payment by the
Fund of initial or variation margin in connection with futures contracts or
related options thereon is not considered the purchase of a security on margin.
 
   6. Invest more than 10% of its total assets in "illiquid securities"
(securities for which market quotations are not readily available) and
repurchase agreements which have a maturity of longer than seven days.
Generally, OTC options and the assets used as "cover" for written OTC options
are illiquid securities. However, the Fund is permitted to treat the securities
it uses as cover for written OTC options as liquid provided it follows a
procedure whereby it will sell OTC options only to qualified dealers who agree
that the Fund may repurchase such options at a maximum price to be calculated
pursuant to a predetermined formula set forth in the option agreement. The
formula may vary from agreement to agreement, but is generally based on a
multiple of the premium received by the Fund for writing the option plus the
amount, if any, of the options intrinsic value. An OTC option is considered an
illiquid asset only to the extent that the maximum repurchase price under the
formula exceeds the intrinsic value of the option.
 
    Notwithstanding any other investment policy or restriction, the Fund may
seek to achieve its investment objectives by investing all or substantially all
of its assets in another investment company having substantially the same
investment objectives and policies as the Fund.
 
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 Investment
Manager, shares of the Fund are distributed by the Distributor and offered by
DWR and other dealers 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 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
    
 
                                       21
<PAGE>
   
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 ($25 million for certain
qualified plans), 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 ($25 million
for certain qualified plans) or more and to certain other limited categories of
investors. For the purpose of meeting the minimum $5 million (or $25 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 of the Fund and other Dean Witter Funds that are multiple class funds
("Dean Witter Multi-Class Funds") and shares of Dean Witter Funds sold with a
front-end sales charge ("FSC Funds") and concurrent investments in Class D
shares of the Fund and other Dean Witter Multi-Class Funds will be aggregated.
Subsequent purchases of $100 or more may be made by sending a check, payable to
Dean Witter World Wide Income Trust, 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 $1,000 within the first twelve months. The minimum initial
purchase 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 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,
provided, in the case of Systematic Payroll Deduction Plans, that the
Distributor 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 requested 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
 
                                       22
<PAGE>
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 orders.
 
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 "Redemptions and Repurchases."
 
    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 4.25%. 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 plans are subject to a CDSC scaled down from 2.0% to 1.0% if 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 0.85% of
the lesser of: (a) the average daily aggregate gross sales of the Fund's Class B
shares since the incep-
tion of the Fund (not including reinvestments of dividends or capital gains
distributions), less the average daily aggregate net asset value of the Fund's
Class B shares redeemed since the Fund's inception upon which a CDSC has been
imposed or waived, or (b) 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

    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 0.85% 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 0.85% (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 (or $25 million) minimum
investment amount for Class D shares, holdings of Class A shares in all Dean
Witter Multi-Class Funds, shares of FSC Funds and shares of Dean Witter Funds
for which such 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,
 
                                       25
<PAGE>
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; (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 Dean Witter Multi-Class Funds and shares of FSC Funds. The sales
charge payable on the purchase of the Class A shares of the Fund, the Class A
shares of the other Dean Witter Multi-Class Funds and the shares of the FSC
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 Dean Witter Funds previously
purchased at a price including a front-end sales charge (including shares of the
Fund and other Dean Witter Funds 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 shares of
FSC Funds and Class A and Class D shares that together with the current
investment amount, is equal to at least $5 million ($25 million for certain
qualified plans), 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 shares of other Dean Witter 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 shares of other Dean Witter Funds acquired in exchange for 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,
 
                                       26
<PAGE>
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
such other circumstances as specified in the program's agreements, and
restrictions on transferability of Fund shares);
    
 
   
    (3) employer-sponsored 401(k) and other plans qualified under Section 401(a)
of the Internal Revenue Code ("Qualified Retirement Plans") with at least 200
eligible employees and for which DWT serves as Trustee or DWR's Retirement Plan
Services serves as recordkeeper pursuant to a written Recordkeeping Services
Agreement;
    
 
   
    (4) Qualified Retirement Plans for which DWT serves as Trustee or DWR's
Retirement Plan Services serves as recordkeeper pursuant to a written
Recordkeeping Services Agreement;
    
 
    (5) investors who are clients of a Dean Witter account executive who joined
Dean Witter from another investment firm within six months prior to the date of
purchase of Fund shares by such investors, if the shares are being purchased
with the proceeds from a redemption of shares of an open-end proprietary mutual
fund of the account executive's previous firm which imposed either a front-end
or deferred sales charge, provided such purchase was made within sixty days
after the redemption and the proceeds of the redemption had been maintained in
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.
 
    No CDSC will be imposed on redemptions of shares purchased pursuant to
paragraphs (1), (2) or (5), above.
 
    For further information concerning purchases of the Fund's shares, contact
DWR or another Selected Broker-Dealer or consult the Statement of Additional
Information.
 
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 Qualified Retirement Plans,
three years) preceding the redemption. In addition, Class B shares are subject
to an annual 12b-1 fee of 0.85% of the lesser of: (a) the average daily
aggregate gross sales of the Fund's Class B shares since the inception of the
Fund (not including reinvestments of dividends or capital gains distributions),
less the average daily aggregate net asset value of the Fund's Class B shares
redeemed since the Fund's inception upon which a CDSC has been imposed or
waived, or (b) 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 sub-
ject 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
 
                                       27
<PAGE>
will depend upon how long the shares have been held, as set forth in the
following table:

    In the case of Class B shares of the Fund purchased on or after July 28,
1997 by Qualified Retirement Plans for which DWT serves as Trustee or DWR's
Retirement Plan Services serves as recordkeeper pursuant to a written
Recordkeeping Services Agreement, shares held for three years or more after
purchase (calculated as described in the paragraph above) will not be subject to
any CDSC upon redemption. However, shares redeemed earlier than three years
after purchase may be subject to a CDSC (calculated as described in the
paragraph above), the percentage of which will depend on how long the shares
have been held, as set forth in the following table:

    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 Qualified Retirement 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 Qualified
Retirement Plans, three years) prior to the redemption; and (iii) the current
net asset value of shares purchased through reinvestment of dividends or
distributions and/or shares acquired in exchange for shares of FSC Funds or of
other Dean Witter Funds acquired in exchange for such shares. 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
Qualified Retirement Plan which offers investment companies managed by the
Investment Manager or its subsidiary, Dean Witter Services Company Inc., as
self-directed investment alternatives and for which DWT serves as Trustee or
DWR's Retirement Plan Services serves as recordkeeper pursuant to a written
Recordkeeping Services Agreement ("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
    
 
                                       28
<PAGE>
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.  All shares of the Fund held prior to July 28,
1997 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 conversion 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 Qualified Retirement Plan for which DWT serves as
Trustee or DWR's Retirement Plan Services serves as recordkeeper pursuant to a
written Recordkeeping Services Agreement, 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 Dean Witter 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 Dean Witter 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
 
                                       29
<PAGE>
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 0.85% 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.
 
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 ($25 million for
Qualified Retirement Plans for which DWT serves as Trustee or DWR's Retirement
Plan Services serves as recordkeeper pursuant to a written Recordkeeping
Services Agreement) 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 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) 401(k) plans established by DWR and SPS Transaction Services, Inc. (an
affiliate of DWR) for their employees; (iv) certain Unit Investment Trusts
sponsored by DWR; (v) certain other open-end investment companies whose shares
are distributed by the Distributor; and (vi) 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 (or $25 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 Dean Witter 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 (or $25 million) minimum investment amount, holdings of
Class A shares in all Dean Witter Multi-Class Funds, shares of FSC Funds and
shares of Dean Witter Funds for which such 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 0.85% 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 0.85% of the lesser of: (a) the average daily
aggregate gross sales of the Fund's Class B
 
                                       30
<PAGE>
shares since the inception of the Fund (not including reinvestments of dividends
or capital gains distributions), less the average daily aggregate net asset
value of the Fund's Class B shares redeemed since the Fund's inception upon
which a CDSC has been imposed or waived, or (b) 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
0.20% and 0.25% of the average daily net assets of each of these Classes,
respectively, 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 October 31, 1997, Class B shares of the Fund
accrued payments under the Plan amounting to $881,250, which amount is equal to
0.85% of the average daily net assets of Class B for the fiscal year. These
payments accrued under the Plan were calculated pursuant to clause (b) of the
compensation formula under the Plan. All shares held prior to July 28, 1997 have
been designated Class B shares. For the fiscal period July 28 through October
31, 1997, Class A and Class C shares of the Fund accrued payments under the Plan
amounting to $169 and $165, respectively, which amounts on an annualized basis
are equal to 0.25% and 0.85% of the average daily net assets of Class A and
Class C, 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 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 such
excess amounts, including the carrying charge described above, totalled
$8,370,199 at October 31, 1997, which was equal to 8.77% of the net assets of
the Fund on such date. 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.
    
 
                                       31
<PAGE>
   
    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 0.85% 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 unreimbursed expenses representing a gross sales commission credited to
account executives at the time of sale totalled $715 in the case of Class C at
December 31, 1997, which amount was equal to 0.61% of the net assets of Class C
on such date, and that there were no such expenses that may be reimbursed in the
subsequent year in the case of Class A 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
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); 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
Investment Manager 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 Fund's Trustees. For valuation purposes, quotations of foreign portfolio
securities, other assets and liabilities and forward contracts stated in foreign
currency are translated into U.S. dollar equivalents at the prevailing market
rates prior to the close of the New York Stock Exchange.
 
    Short-term debt 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.
 
    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 and coupon as the
evaluation model parameters, and/or research 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.
 
    Generally, trading in foreign securities, as well as corporate bonds, United
States government securities and money market instruments, is substantially
completed each day at various times prior
 
                                       32
<PAGE>
to the close of the New York Stock Exchange. The values of such securities used
in computing the net asset value of the Fund's shares are determined as of such
times. Foreign currency exchange rates are also generally determined prior to
the close of the New York Stock Exchange. Occasionally, events which affect the
values of such securities and such exchange rates may occur between the times at
which they are determined and the close of the New York Stock Exchange and will
therefore not be reflected in the computation of the Fund's net asset value. If
events materially affecting the value of such securities occur during such
period, then these securities will be valued at their fair value as determined
in good faith under procedures established by and under the supervision of the
Trustees.
 
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 Dean Witter 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 "Redemptions and Repurchases").
 
    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 "Redemptions and Repurchases --
Involuntary Redemption").
 
    INVESTMENT OF DIVIDENDS AND 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 thirty 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 "Redemptions and Repurchases.")
 
    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
 
                                       33
<PAGE>
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 account executive or the Transfer
Agent.
 
EXCHANGE PRIVILEGE
 
   
    Shares of each Class may be exchanged for shares of the same Class of any
other Dean Witter Multi-Class Fund without the imposition of any exchange fee.
Shares may also be exchanged for shares of the following funds: Dean Witter
Short-Term U.S. Treasury Trust, Dean Witter Limited Term Municipal Trust, Dean
Witter Short-Term Bond Fund, Dean Witter Intermediate Term U.S. Treasury Trust
and five Dean Witter funds which are money market funds (the "Exchange Funds").
Class A shares may also be exchanged for shares of Dean Witter Multi-State
Municipal Series Trust and Dean Witter Hawaii Municipal Trust, which are Dean
Witter Funds sold with a front-end sales charge ("FSC Funds"). Class B shares
may also be exchanged for shares of Dean Witter Global Short-Term Income Fund
Inc. ("Global Short-Term"), which is a Dean Witter Fund offered with a CDSC.
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 Dean Witter Multi-Class Fund, any FSC Fund, Global
Short-Term 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
Dean Witter Multi-Class Funds, FSC Funds or Global Short-Term 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 Dean Witter Multi-Class
Fund or shares of Global Short-Term, the holding period previously frozen when
the first exchange was made resumes on the last day of the month in which shares
of a Dean Witter Multi-Class Fund or shares of Global Short-Term Fund are
reacquired. Thus, the CDSC is based upon the time (calculated as described
above) the shareholder was invested in shares of a Dean Witter Multi-Class Fund
or in shares of Global Short-Term (see "Purchase of Fund Shares"). In the case
of exchanges of Class A shares which are subject to a CDSC, the holding period
also includes the time (calculated as described above) the shareholder was
invested in shares of a FSC Fund. In the case of shares exchanged into an
Exchange Fund on or after April 23, 1990, 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
incurred on or after that date which are attributable to those shares. (Exchange
Fund 12b-1 distribution fees are described in the prospectuses for those funds.)
Class B shares of the Fund acquired in exchange for Class B shares of another
Dean Witter Multi-Class Fund having a different CDSC schedule than that of this
Fund will be subject to the higher CDSC schedule, even if such shares are
subsequently re-exchanged for shares of the fund with the lower CDSC schedule.
    
 
                                       34
<PAGE>
    ADDITIONAL INFORMATION REGARDING EXPENSES. Purchases and exchanges should be
made for investment purposes only. A pattern of frequent exchanges may be deemed
by the Investment Manager to be abusive and contrary to the best interests of
the Fund's other shareholders and, at the Investment 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 and each of the other Dean
Witter 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 Dean Witter 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 of the Fund 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 purposes 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 Dean Witter
Funds (for which the Exchange Privilege is available) pursuant to this Exchange
Privilege by contacting their 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. Such procedures may
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 may also
be recorded. If such procedures are not employed, the Fund may be liable for any
losses due to unauthorized or fradulent 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
 
                                       35
<PAGE>
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
with the Dean Witter Funds in the past.
 
    Shareholders should contact their DWR or other Selected Broker-Dealer
account executive or the Transfer Agent for further information about the
Exchange Privilege.
 
REDEMPTIONS AND REPURCHASES
- --------------------------------------------------------------------------------
 
    REDEMPTION.  Shares of each Class of the Fund can be redeemed for cash at
any time at the 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 certificates with a
written request for redemption along with any additional information required by
the Transfer Agent.
 
    REPURCHASE.  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 (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 above under "Redemption."
 
    PAYMENT FOR SHARES REDEEMED OR REPURCHASED.  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
redeemed or repurchased and has not previously exercised this reinstatement
privilege may, within 35 days after the date of the 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 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.
 
                                       36
<PAGE>
    INVOLUNTARY REDEMPTION.  The Fund reserves the right, on sixty 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, 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 the shareholder sixty
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 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 monthly 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 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 net short-term and long-term capital gains to shareholders and remain
qualified as a regulated investment company under Subchapter M of the Code, it
is not expected that the Fund will be required to pay any federal income tax on
such income and capital gains.
 
   
    Gains or losses on the Fund's transactions in certain listed options on
securities and on futures and options on futures generally are treated as 60%
long-term gain/loss and 40% short-term gain/loss. When the Fund engages in
options and futures transactions, various tax regulations applicable to the Fund
may have the effect of causing the Fund to recognize a gain or loss for tax
purposes before that gain or loss is realized, or to defer recognition of a
realized loss for tax purposes. Recognition, for tax purposes, of an unrealized
loss may result in a lesser amount of the Fund's realized net gains being
available for distribution.
    
 
    Shareholders will normally have to pay federal income taxes, and any
applicable state and/or local 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 and net short-term capital gains,
are taxable to the shareholder as ordinary dividend income regardless of whether
the shareholder receives such distributions 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, for tax purposes, to have
been received by the shareholder in the prior year.
 
                                       37
<PAGE>
    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.
 
    The Fund may at times make payments from sources other than income or net
capital gains. Payments from such sources will, in effect, represent a return of
a portion of each shareholder's investment. All, or a portion, of such payments
will 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,
including information as to the portion taxable as ordinary income and the
portion taxable as long-term capital gains. Shareholders will also be notified
of their proportionate share of long-term capital gains distributions that are
eligible for a reduced rate of tax under the Taxpayer Relief Act of 1997.
    
 
    To avoid being subject to a 31% federal backup withholding tax on taxable
dividends, capital gains distributions and the proceeds of redemptions and
repurchases, shareholders' taxpayer identification numbers must be furnished and
certified as to their accuracy.
 
    Dividends, interest and gains received by the Fund may give rise to
withholding and other taxes imposed by foreign countries. If it qualifies for
and has made the appropriate election with the Internal Revenue Service, the
Fund will report annually to its shareholders the amount per share of such
taxes, to enable shareholders to claim United States foreign tax credits or
deductions with respect to such taxes. In the absence of such an election, the
Fund would deduct foreign tax in computing the amount of its distributable
income.
 
    The foregoing discussion relates solely to the federal income tax
consequences of an investment in the Fund. Distributions may also be subject to
state and local taxes; therefore, each shareholder is advised to consult his or
her own tax adviser.
 
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
maximum offering price 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 Fund's yield
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 periods of one, five
and ten years, as well as over the life of the Fund. 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
 
                                       38
<PAGE>
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. and Salomon Brothers Treasury
Index, Salomon Brothers World Government Index, Salomon Brothers Corporate
Index, Shearson Lehman Corporate/Government Bond Index and Donahue's Money
Market Index).
 
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
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, the possibility of the Fund
being unable to meet its obligations is remote and, in the opinion of
Massachusetts counsel to the Fund, the risk to Fund shareholders of personal
liability is remote.
 
    CODE OF ETHICS.  Directors, officers and employees of InterCapital, Dean
Witter Services Company Inc. and the Distributor are subject to a strict Code of
Ethics adopted by those companies. The Code of Ethics is intended to ensure that
the interests of shareholders and other clients are placed ahead of any personal
interest, that no undue personal benefit is obtained from a person's employment
activities and that actual and potential conflicts of interest are avoided. To
achieve these goals and comply with regulatory requirements, the Code of Ethics
requires, among other things, that personal securities transactions by employees
of the companies be subject to an advance clearance process to monitor that no
Dean Witter Fund is engaged at the same time in a purchase or sale of the same
security. The Code of Ethics bans the purchase of securities in an initial
public offering, and also prohibits engaging in futures and options transactions
and profiting on short-term trading (that is, a purchase within sixty days of a
sale or a sale within sixty days of a purchase) of a security. In addition,
investment personnel may not purchase or sell a security for their personal
account within thirty days before or after any transaction in any Dean Witter
Fund managed by them. Any violations of the Code of Ethics are subject to
sanctions, including reprimand, demotion or suspension or
 
                                       39
<PAGE>
termination of employment. The Code of Ethics comports with regulatory
requirements and the recommendations in the 1994 report by the Investment
Company Institute Advisory Group on Personal Investing.
 
    MASTER/FEEDER CONVERSION.  The Fund reserves the right to seek to achieve
its investment objectives by investing all of its investable assets in a
non-diversified, open-end management investment company having the same
investment objectives and policies and substantially the same investment
restrictions as those applicable to the Fund.
 
    SHAREHOLDER INQUIRIES.  All inquiries regarding the Fund should be directed

this Prospectus.

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
October 14, 1988.
 
THE INVESTMENT MANAGER
 
    Dean Witter InterCapital Inc. (the "Investment Manager" or "InterCapital"),
a Delaware corporation, whose address is Two World Trade Center, New York, New
York 10048, is the Fund's Investment Manager. 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 InterCapital. (As
hereinafter used in this Statement of Additional Information, the terms
"InterCapital" and "Investment Manager" refer to DWR's InterCapital Division
prior to the internal reorganization and 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 Investment Manager, 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."

collectively referred to as the Dean Witter Funds.
 
   
    In addition, Dean Witter Services Company Inc. ("DWSC"), a wholly-owned
subsidiary of InterCapital, serves as manager for the following companies for
which TCW Funds Management, Inc. is the investment adviser: TCW/DW Core Equity
Trust, TCW/DW North American Government Income Trust, TCW/DW Latin American

Opportunities Trust, TCW/DW Term Trust 2000, TCW/DW Term Trust 2002 and TCW/DW
Term Trust 2003 (the "TCW/DW Funds"). InterCapital also serves as: (i)
sub-adviser to Templeton Global Opportunities Trust, an open-end investment
company; (ii) administrator of The BlackRock Strategic Term Trust Inc., a
closed-end investment company; (iii) sub-administrator of MassMutual
Participation Investors and Templeton Global Governments Income Trust,
closed-end investment companies; and (iii) investment adviser of Offshore
Dividend Growth Fund and Offshore Money Market Fund, mutual funds established
under the laws of the Cayman Islands and available only to investors who are
participants in DWR's International Active Assets Account program and are
neither citizens nor residents of the United States.
    
 
    Pursuant to an Investment Management Agreement (the "Agreement") with the
Investment Manager, the Fund has retained the Investment Manager to manage the
investment of the Fund's assets, including the placing of orders for the
purchase and sale of portfolio securities. The Investment Manager 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 objectives.
 
    Under the terms of the Agreement, in addition to managing the Fund's
investments, the Investment Manager maintains certain of the Fund's books and
records and furnishes, at its own expense, such office space, facilities,
equipment, clerical help and bookkeeping and certain 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 federal and state securities commissions
(except insofar as the participation or assistance of independent accountants
and attorneys is, in the opinion of the Investment Manager, necessary or
desirable). In addition, the Investment Manager pays the salaries of all
personnel, including officers of the Fund, who are employees of the Investment
Manager. The Investment Manager also bears the cost of telephone service, heat,
light, power and other utilities provided to the Fund.
 
    Effective December 31, 1993, pursuant to a Services Agreement between
InterCapital and DWSC, DWSC began to provide the administrative services to the
Fund which were previously performed directly by InterCapital. On April 17,
1995, DWSC was reorganized in the State of Delaware, necessitating the entry
into a new Services Agreement by InterCapital and DWSC on that date. The
foregoing internal reorganizations did not result in any change in the nature or
scope of the administrative services being provided to the Fund or any of the
fees being paid by the Fund for the overall services being performed under the
terms of the existing Agreement.
 
   
    Expenses not expressly assumed by the Investment Manager under the 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; 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
    
 
                                       4
<PAGE>
Fund's shareholders; all expenses of shareholders' and Trustees' meetings and of
preparing, printing and mailing 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 Investment Manager or any corporate
affiliate of the Investment Manager; 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 Investment Manager (not including compensation or expenses of attorneys
who are employees of the Investment Manager) 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.
 
   
    As full compensation for the services and facilities furnished to the Fund
and expenses of the Fund assumed by the Investment Manager, the Fund pays the
Investment Manager monthly compensation calculated daily at an annual rate of
0.75% of the daily net assets of the Fund up to $250 million; 0.60% of the
portion of the daily net assets of the Fund exceeding $250 million but not
exceeding $500 million; 0.50% of the portion of the daily net assets of the Fund
exceeding $500 million but not exceeding $750 million; 0.40% of the portion of
the daily net assets of the Fund exceeding $750 million but not exceeding $1
billion; and 0.30% of the daily net assets of the Fund exceeding $1 billion. The
management fee is allocated among the Classes pro rata based on the net assets
attributable to each Class. For the fiscal years ended October 31, 1995, 1996
and 1997, the Fund accrued to the Investment Manager total compensation in the
amounts of $1,169,823, $933,697 and 778,248, respectively.
    
 
    The Agreement provides that in the absence of willful misfeasance, bad
faith, gross negligence or reckless disregard of its obligations thereunder, the
Investment Manager is not liable to the Fund or any of its investors for any act
or omission by the Investment Manager or for any losses sustained by the Fund or
its investors. The Agreement in no way restricts the Investment Manager from
acting as investment manager or adviser to others.
 
    The Agreement was initially approved by the Board of Trustees on February
21, 1997 and by the shareholders of the Fund at a Special Meeting of
Shareholders held on May 21, 1997. The Agreement is substantially identical to a
prior investment management agreement which was initially approved by the Board
of Trustees on October 30, 1992 and by the shareholders of the Fund at a Special
Meeting of Shareholders held on January 12, 1993. The Agreement took effect on
May 31, 1997 upon the consummation of the merger of Dean Witter, Discover & Co.
with Morgan Stanley Group Inc. The Agreement may be terminated at any time,
without penalty, on thirty days' notice by the Board of Trustees of the Fund, by
the holders of a majority, as defined in the Investment Company Act of 1940 (the
"Act"), of the outstanding shares of the Fund, or by the Investment Manager. The
Agreement will automatically terminate in the event of its assignment (as
defined in the Act).
 
   
    Under its terms, the Agreement had an initial term ending April 30, 1999,
and will remain in effect 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 Trustees of the Fund who are
not parties to the Agreement or "interested persons" (as defined in the Act) of
any such party (the "Independent Trustees"), which vote must be cast in person
at a meeting called for the purpose of voting on such approval.

name "Dean Witter" from its name if DWR or its parent company shall so request.

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 directors or trustees for all of the Dean Witter Funds, and are
referred to in this section as Trustees. As of the date of this Statement of
Additional Information, there are a total of 84 Dean Witter Funds, comprised of
128 portfolios. As of December 31, 1997, the Dean Witter Funds had total net
assets of approximately $93.7 billion and more than six million shareholders.
    
 
   
    Seven Trustees (77% of the total number) have no affiliation or business
connection with InterCapital or any of its affiliated persons and do not own any
stock or other securities issued by InterCapital's parent company, MSDWD. These
are the "disinterested" or "independent" Trustees. The other two Trustees (the
"management Trustees") are affiliated with InterCapital. Four of the seven
independent Trustees are also Independent Trustees of the TCW/DW Funds.
    
 
   
    Law and regulation establish both general guidelines and specific duties for
the Independent Trustees. The Dean Witter 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 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, 1997,
the three Committees held a combined total of seventeen meetings. The Committees
hold some meetings at InterCapital's offices and some outside InterCapital.
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. Most of the Dean Witter Funds have such a plan.
    
 
                                       9
<PAGE>
   
    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
    
 
   
    The Chairman of the Committee of the Independent Trustees and the Audit
Committee 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 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 Dean Witter Funds and as an Independent Trustee and as Chairman
of the Committee of the Independent Trustees and the Audit Committee of the
TCW/DW 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 DEAN
WITTER FUNDS
    
 
   
    The Independent Trustees and the Funds' management believe that having the
same Independent Trustees for each of the Dean Witter 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 Dean Witter Funds.
    
 
   
COMPENSATION OF INDEPENDENT TRUSTEES
    
 
   
    The Fund pays each Independent Trustee an annual fee of $800 plus a per
meeting fee of $50 for meetings of the Board of Trustees or committees of the

    As of the date of this Statement of Additional Information, 57 of the Dean
Witter Funds, including the Fund, 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
    
 
                                       11
<PAGE>
   
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.
    
 
   
    The following table illustrates the retirement benefits accrued to the
Fund's Independent Trustees by the Fund for the fiscal year ended October 31,
1997 and by the 57 Dean Witter Funds (including the Fund) for the year ended
December 31, 1997, and the estimated retirement benefits for the Fund's
Independent Trustees, to commence upon their retirement, from the Fund as of
October 31, 1997 and from the 57 Dean Witter Funds as of December 31, 1997.

    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
- --------------------------------------------------------------------------------
 
CONVERTIBLE SECURITIES
 
    The Fund may invest in fixed-income securities which are convertible into
common stock. 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).
 
                                       12
<PAGE>
    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, will 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. Convertible securities may be purchased by the Fund
at varying price levels above their investment values and/or their conversion
values in keeping with the Fund's objectives.
 
WARRANTS
 
    The Fund may acquire warrants which are attached to fixed-income securities
purchased for its portfolio and hold such warrants until the Investment Manager
determines it is prudent to sell. 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. If warrants remain unexercised at the
end of the exercise period, they will lapse and the Fund's investment in them
will be lost. The prices of warrants do not necessarily move parallel to the
prices of the underlying securities.
 
U.S. GOVERNMENT SECURITIES
 
    Securities issued by the U.S. Government, its agencies or instrumentalities
in which the Fund may invest 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 is guaranteed by the U.S. Government. Such values and
yield will fluctuate with changes in prevailing 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.
 
                                       13
<PAGE>
ZERO COUPON TREASURY SECURITIES
 
    A portion of the U.S. Government securities purchased by the Fund may be
"zero coupon" Treasury securities. These are U.S. Treasury bills, notes and
bonds which have been stripped of their unmatured interest coupons and receipts
or which are certificates representing interests in such stripped debt
obligations and coupons. Such securities are purchased at a discount from their
face amount, giving the purchaser the right to receive their full value at
maturity. A zero coupon security pays no interest to its holder during its life.
Its value to an investor consists of the difference between its face value at
the time of maturity and the price for which it was acquired, which is generally
an amount significantly less than its face value (sometimes referred to as a
"deep discount" price). The Fund intends to invest in such zero coupon treasury
securities as STRIPS, Treasury Receipts, Physical Coupons, and Proprietary
Receipts.
 
    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 if
prevailing interest rates rise. For this reason, zero coupon securities are
subject to substantially greater market price fluctuations during periods of
changing prevailing interest rates than are comparable debt securities which
make current distributions of interest. 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.
 
    Currently the only U.S. Treasury security issued without coupons is the
Treasury bill. However, in the last few years a number of banks and brokerage
firms have separated ("stripped") the principal portions from the coupon
portions of the U.S. Treasury bonds and notes and sold them separately in the
form of receipts or certificates representing undivided interests in these
instruments (which instruments are generally held by a bank in a custodial or
trust account).
 
MONEY MARKET INSTRUMENTS
 
    As stated in the Prospectus, the 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 $1,000,000,000 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
$1,000,000,000 or more;
 
    OBLIGATIONS OF SAVINGS INSTITUTIONS.  Certificates of deposit of savings
banks and savings and loan associations, having total assets of $1,000,000,000
or more;
 
    FULLY INSURED CERTIFICATES OF DEPOSIT.  Certificates of deposit of banks and
savings institutions, having total assets of less than $1,000,000,000, 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 10% or less of the Fund's total assets in all such
obligations and in all illiquid assets, in the aggregate;
 
   
    COMMERCIAL PAPER.  Commercial paper rated within the two highest grades by
Standard & Poor's ("S&P") or the highest grade by Moody's or, if not rated,
issued by a company having an outstanding debt issue rated at least AA by S&P or
Aa by Moody's.
    
 
                                       14
<PAGE>
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 and their customers. Such forward contracts will only be entered into
with United States banks and their foreign branches, insurance companies and
other dealers whose assets total $1 billion or more 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.
 
    When management of the Fund believes that the currency of a particular
foreign country may suffer a substantial movement against the U.S. dollar, it
may enter into a forward contract to purchase or 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 portfolio securities denominated in such
foreign currency. 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 Investment Manager 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, high grade debt securities or other liquid
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 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. 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
 
                                       15
<PAGE>
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 currency 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 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.
 
OPTIONS AND FUTURES TRANSACTIONS
 
    As discussed in the Prospectus, 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 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 (currently the Chicago Board Options
Exchange, American Stock Exchange, New York Stock Exchange, Pacific Stock
Exchange and Philadelphia Stock Exchange) and are written in over-the-counter
transactions ("OTC Options"). Listed options are issued by the Options Clearing
Corporation ("OCC"). 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 interest in options
written on Treasury bonds and notes tends to center on the most recently
auctioned issues, the exchanges on which such securities trade will not continue
indefinitely to introduce options with new expirations to replace expiring
options on particular issues. Instead, the expirations introduced at the
commencement of options trading on a particular issue will be allowed to run
their course, with the possible addition of a limited
 
                                       16
<PAGE>
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.
 
    OPTIONS ON GNMA CERTIFICATES.  Currently, options on GNMA Certificates are
only traded over-the-counter. Since the remaining principal balance of GNMA
Certificates declines each month as a result of mortgage payments, the Fund, as
a writer of a GNMA call holding GNMA Certificates as "cover" to satisfy its
delivery obligation in the event of exercise, may find that the GNMA
Certificates it holds no longer have a sufficient remaining principal balance
for this purpose. Should this occur, the Fund will purchase additional GNMA
Certificates from the same pool (if obtainable) or replacement GNMA Certificates
in the cash market in order to maintain its cover. A GNMA Certificate held by
the Fund to cover an option position in any but the nearest expiration month may
cease to represent cover for the option in the event of a decline in the GNMA
coupon rate at which new pools are originated under the FHA/VA loan ceiling in
effect at any given time, as such decline may increase the prepayments made on
other mortgage pools. If this should occur, the Fund will no longer be covered,
and the Fund will either enter into a closing purchase transaction or replace
such Certificate with a Certificate which represents cover. When the Fund closes
out its position or replaces such Certificate, it may realize an unanticipated
loss and incur transaction costs.
 
    OPTIONS ON FOREIGN CURRENCIES.  The Fund may purchase and write options on
foreign currencies for purposes similar to those involved with investing in
forward foreign currency exchange contracts. For example, in order to protect
against declines in the dollar value of portfolio securities which are
denominated in a foreign currency, the Fund may purchase put options on an
amount of such foreign currency equivalent to the current value of the portfolio
securities involved. As a result, the Fund would be enabled to sell the foreign
currency for a fixed amount of U.S. dollars, thereby "locking in" the dollar
value of the portfolio securities (less the amount of the premiums paid for the
options). Conversely, the Fund may purchase call options on foreign currencies
in which securities it anticipates purchasing are denominated to secure a set
U.S. dollar price for such securities and protect against a decline in the value
of the U.S. dollar against such foreign currency. The Fund may also purchase
call and put options to close out written option positions.
 
    The Fund may also write call options on foreign currency to protect against
potential declines in its portfolio securities which are denominated in foreign
currencies. If the U.S. dollar value of the portfolio securities falls as a
result of a decline in the exchange rate between the foreign currency in which
it is denominated and the U.S. dollar, then a loss to the Fund occasioned by
such value decline would be ameliorated by receipt of the premium on the option
sold. At the same time, however, the Fund gives up the benefit of any rise in
value of the relevant portfolio securities above the exercise price of the
option and, in fact, only receives a benefit from the writing of the option to
the extent that the value of the portfolio securities falls below the price of
the premium received. A put option on a foreign currency would be written by the
Fund for the same reason it would purchase a call option, namely, to hedge
against an increase in the U.S. dollar value of a foreign security which the
Fund anticipates purchasing. Here, the receipt of the premium would offset, to
the extent of the size of the premium, any increased cost to the Fund resulting
from an increase in the U.S. dollar value of the foreign security. However, the
Fund could not benefit from any decline in the cost of the foreign security
which is greater than the price of the premium received. The Fund may also write
options to close out long put and call option positions.
 
                                       17
<PAGE>
    The markets in foreign currency options are relatively new and the Fund's
ability to establish and close out positions on such options is subject to the
maintenance of a liquid secondary market. Although the Fund will not purchase or
write such options unless and until, in the Investment Manager's opinion, the
market for them has developed sufficiently to ensure that the risks in
connection with such options are not greater than the risks in connection with
the underlying currency, there can be no assurance that a liquid secondary
market will exist for a particular option at any specific time. In addition,
options on foreign currencies are affected by all of those factors which
influence foreign exchange rates and investments generally.
 
    The value of a foreign currency option depends upon the value of the
underlying currency relative to the U.S. dollar. As a result, the price of the
option position may vary with changes in the value of either or both currencies
and have no relationship to the investment merits of a foreign security,
including foreign securities held in a "hedged" investment portfolio. Because
foreign currency transactions occurring in the interbank market involve
substantially larger amounts than those that may be involved in the use of
foreign currency options, investors may be disadvantaged by having to deal in an
odd lot market (generally consisting of transactions of less than $1 million)
for the underlying foreign currencies at prices that are less favorable than for
round lots.
 
    There is no systematic reporting of last sale information for foreign
currencies or any regulatory requirement that quotations available through
dealers or other market sources be firm or revised on a timely basis. Quotation
information available is generally representative of very large transactions in
the interbank market and thus may not reflect relatively smaller transactions
(i.e., less than $1 million) where rates may be less favorable. The interbank
market in foreign currencies is a global, around-the-clock market. To the extent
that the U.S. options markets are closed while the markets for the underlying
currencies remain open, significant price and rate movements may take place in
the underlying markets that are not reflected in the options market.
 
    OTC OPTIONS.  Exchange-listed options are issued by the OCC 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.
 
    COVERED CALL WRITING.  As stated in the Prospectus, the Fund is permitted to
write covered call options on portfolio securities and the currencies in which
they are denominated, without limit, in order to aid in achieving its investment
objectives. 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 (currency) 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 security (currency) 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 (currency) of the written option, where the exercise price
of the call used for coverage is equal to or less than the exercise price of the
call written or greater than the exercise price of the call written if the 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.
 
    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 earn a higher level of current income than it
would earn from holding the underlying securities (currencies) alone. Moreover,
the premium received will offset a portion of the potential loss incurred by the
Fund if the securities
 
                                       18
<PAGE>
(currencies) underlying the option are ultimately sold (exchanged) by the Fund
at a loss. The premium received will fluctuate with varying economic market
conditions. If the market value of the portfolio securities (or the currencies
in which they are denominated) upon which call options have been written
increases, 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.
 
    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
(currency) against payment of the exercise price on any calls it has written
(exercise of certain listed and OTC options may be limited to specific
expiration dates). This obligation is terminated upon the expiration of the
option period or at such earlier time when the writer effects a closing purchase
transaction. A closing purchase transaction is accomplished by purchasing an
option of the same series as the option previously written. However, once the
Fund has been assigned an exercise notice, the Fund will be unable to effect a
closing purchase transaction.
 
    Closing purchase transactions are ordinarily effected to realize a profit on
an outstanding call option, to prevent an underlying security (currency) from
being called, to permit the sale of an underlying security (or the exchange of
the underlying currency) or to enable the Fund to write another call option on
the underlying security (currency) with either a different exercise price or
expiration date or both. 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 (currency). Conversely, a gain resulting from a closing
purchase transaction could be offset in whole or in part or exceeded by a
decline in the market value of the underlying security (currency).
 
    If a call option expires unexercised, 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
(currency) during the option period. If a call option is exercised, the Fund
realizes a gain or loss from the sale of the underlying security (currency)
equal to the difference between the purchase price of the underlying security
(currency) and the proceeds of the sale of the security (currency) plus the
premium received for the option less the commission paid.
 
    Options written by the Fund will normally have expiration dates of up to
eighteen months 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 Transactions," below.
 
    COVERED PUT WRITING.  As stated in the Prospectus, 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 (currency) as the underlying
security of the written option, where the exercise price of the purchased option
is equal to or more than the exercise price of the put written or less than the
exercise price of the put written if the marked to market difference is
maintained by the Fund in cash, U.S. Government securities or other liquid
portfolio securities which the Fund holds in a segregated account maintained at
its Custodian. In writing puts, the Fund assumes the risk of loss should the
market value of the underlying security (currency) decline below the exercise
price of the option (any loss being decreased by the receipt of the premium on
the option written). In the case of listed options, during the option period,
the Fund may be required, at any time, to make payment of the exercise price
against delivery of the underlying security (currency). The operation of and
limitations on covered put options in other respects are substantially identical
to those of call options.
 
                                       19
<PAGE>
    The Fund will write put options for three purposes: (1) to receive the
income derived from the premiums paid by purchasers; (2) when the Investment
Manager wishes to purchase the security (or a security denominated in the
currency underlying the option) underlying the option at a price lower than its
current market price, in which case it will write the covered put at an exercise
price reflecting the lower purchase price sought; and (3) to close out a long
put option position. The potential gain on a covered put option is limited to
the premium received on the option (less the commissions paid on the
transaction) while the potential loss equals the differences between the
exercise price of the option and the current market price of the underlying
securities (currencies) when the put is exercised, offset by the premium
received (less the commissions paid on the transaction).
 
    PURCHASING CALL AND PUT OPTIONS.  As stated in the Prospectus, the Fund may
purchase listed and OTC call and put options in amounts equalling up to 5% of
its total assets. The Fund may purchase a call option in order to close out a
covered call position (see "Covered Call Writing" above), to protect against an
increase in price of a security it anticipates purchasing or, in the case of a
call option on foreign currency, to hedge against an adverse exchange rate move
of the currency in which the security it anticipates purchasing is denominated
vis-a-vis the currency in which the exercise price is denominated. If the price
of the security (or value of the currency in which it is denominated) underlying
the option fails to rise above the exercise price by an amount exceeding the
price of the option premium, the Fund will sustain a loss equal to some or all
of the premium price. The purchase of the call option to effect a closing
transaction on a call written over-the-counter may be a listed or an OTC option.
In either case, the call purchased is likely to be on the same securities
(currencies) and have the same terms as the written option. If purchased
over-the-counter, the option would generally be acquired from the dealer or
financial institution which purchased the call written by the Fund.
 
    The Fund may purchase put options on securities (currencies) which it holds
in its portfolio only to protect itself against a decline in the value of the
security. If the value of the underlying security (currency) were to fall below
the exercise price of the put purchased in an amount greater than the premium
paid for the option, the Fund would incur no additional loss. The Fund may also
purchase put options to close out written put positions in a manner similar to
call options closing purchase transactions. In addition, the Fund may sell a put
option which it has previously purchased prior to the sale of the securities
(currencies) underlying such option. Such a sale would result in a net gain or
loss depending 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.
And such gain or loss could be offset in whole or in part by a change in the
market value of the underlying security (currency). If a put option purchased by
the Fund expired without being sold or exercised, the premium would be lost.
 
    RISKS OF OPTIONS TRANSACTIONS.  During the option period, the covered call
writer has, in return for the premium on the option, given up the opportunity
for capital appreciation above the exercise price should the market price of the
underlying security (or the value of its denominated currency) increase, but has
retained the risk of loss should the price of the underlying security (or the
value of its denominated currency) decline. The secured put writer also retains
the risk of loss should the market value of the underlying security (or the
value of its denominated currency) 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 OTC option, it cannot sell the underlying security until the
option expires or the option is exercised. Accordingly, a covered call option
writer may not be able to sell an underlying security at a time when it might
otherwise be advantageous to do so. A secured put option writer who is unable to
effect a closing purchase transaction or to purchase an offsetting OTC option
would continue to bear the risk of decline in the market price of the underlying
security until the option
 
                                       20
<PAGE>
expires or is exercised. In addition, a secured 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.
 
    As discussed in the Prospectus, 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 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 Options Clearing Corporation ("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
excercisable in accordance with their terms.
 
    In the event of the bankruptcy of a broker through which the Fund engages in
transactions in options, the Fund could experience delays and/or losses in
liquidating open positions purchased or sold through the broker and/or incur a
loss of all or part of its margin deposits with the broker. Similarly, in the
event of the bankruptcy of the writer of an OTC option purchased by 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 Investment Manager.
 
    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.
 
    The hours of trading for options may not conform to the hours during which
the underlying securities are traded. To the extent that the option markets
close before the markets for the underlying securities, significant price and
rate movements can take place in the underlying markets that cannot be reflected
in the option markets.
 
    The extent to which the Fund may enter into transactions involving options
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).
 
    FUTURES CONTRACTS.  As stated in the Prospectus, the Fund may purchase and
sell interest rate, currency, and index futures contracts ("futures contracts"),
that are traded on U.S. and foreign commodity exchanges, on such underlying
securities as U.S. Treasury bonds, notes and bills and/or any foreign government
fixed-income security ("interest rate" futures), on various currencies
("currency futures") and on such indexes of U.S. and foreign fixed-income
securities as may exist or come into being, such as the Moody's Investment-Grade
Corporate Bond Index ("index" futures).
 
                                       21
<PAGE>
    The Fund will purchase or sell interest rate futures contracts and bond
index futures contracts for the purpose of hedging its fixed-income portfolio
(or anticipated portfolio) against changes in prevailing interest rates and to
alter the Fund's asset allocation in fixed-income securities. If the Investment
Manager anticipates that interest rates may rise and, concomitantly, the price
of fixed-income securities fall, or wishes to decrease the Fund's asset
allocation in fixed-income securities, the Fund may sell an interest rate
futures contract or a bond index futures contract. If declining interest rates
are anticipated or if the Investment Manager wishes to increase the Fund's asset
allocation of fixed-income securities, 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.
 
    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. A futures contract
sale is closed out by effecting a futures contract purchase for the same
aggregate amount of the specific type of security (currency) 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 security (currency) 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.
 
    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 3% 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 of cash or U.S. Government
securities or other liquid portfolio securities called "variation margin," with
the Fund's futures contract clearing broker, which are reflective of price
fluctuations in the futures contract. Currently, interest rate 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.
 
    CURRENCY FUTURES.  Generally, foreign currency futures provide for the
delivery of a specified amount of a given currency, on the exercise date, for a
set exercise price denominated in U.S. dollars or other currency. Foreign
currency futures contracts would be entered into for the same reason and under
the same circumstances as forward foreign currency exchange contracts. The
Investment Manager will assess such factors as cost spreads, liquidity and
transaction costs in determining whether to utilize futures contracts or forward
contracts its in foreign currency transactions and hedging strategy. Currently,
currency futures exist for, among other foreign currencies, the Japanese yen,
West German marks, Canadian dollars, British pound, Swiss franc and European
currency unit.
 
    Purchasers and sellers of foreign currency futures contracts are subject to
the same risks that apply to the buying and selling of futures generally. In
addition, there are risks associated with foreign currency futures contracts and
their use as a hedging device similar to those associated with options on
foreign currencies described above. Further, settlement of a foreign currency
futures contract must occur within
 
                                       22
<PAGE>
the country issuing the underlying currency. Thus, the Fund must accept or make
delivery of the underlying foreign currency in accordance with any U.S. or
foreign restrictions or regulation regarding the maintenance of foreign banking
arrangements by U.S. residents and may be required to pay any fees, taxes or
charges associated with such delivery which are assessed in the issuing country.
 
    Options on foreign currency futures contracts may involve certain additional
risks. Trading options on foreign currency futures contracts is relatively new.
The ability to establish and close out positions on such options is subject to
the maintenance of a liquid secondary market. To reduce this risk, the Fund will
not purchase or write options on foreign currency futures contracts unless and
until, in the Investment Manager's opinion, the market for such options has
developed sufficiently that the risks in connection with such options are not
greater than the risks in connection with transactions in the underlying foreign
currency futures contracts.
 
    INDEX FUTURES CONTRACTS.  As discussed in the Prospectus, 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 gain.
 
    OPTIONS ON FUTURES CONTRACTS.  The Fund may purchase and write call and put
options on futures contracts which are traded on an Exchange and enter into
closing transactions with respect to such options to terminate an existing
position. An option on a futures contract gives the purchaser the right (in
return for the premium paid), to assume a position in a futures contract (a long
position if the option is a call and a short position if the option is a put) at
a specified exercise price at any time during the term of the option. 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 Investment
Manager wished to protect against an increase in interest rates and the
resulting negative impact on the value of a portion of its fixed-income
portfolio, it might write a call option on an interest rate futures contract,
the underlying security of which correlates with the portion of the portfolio
the Investment Manager 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.
 
                                       23
<PAGE>
    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.  As stated
in the Prospectus, the Fund may sell a futures contract to protect against the
decline in the value of securities (or the currency in which they are
denominated) held by the Fund. However, it is possible that the futures market
may advance and the value of securities (or the currency in which they are
denominated) 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 (or the currency in which they are
denominated), and the value of such securities (currencies) 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.
 
    If the Fund has sold a call option in a futures contract, it will cover this
position by holding, in a segregated account maintained at its Custodian, cash,
U.S. Government 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 (currencies) underlying the futures contract or the exercise
price of the option. Such a position may also be covered by owning the
securities (currencies) underlying the futures contract, 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.
 
    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 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.
 
    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
 
                                       24
<PAGE>
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.
 
    In the event of the bankruptcy of a broker through which the Fund engages in
transactions in futures or options thereon, the Fund could experience delays
and/or losses in liquidating open positions purchased or sold through the broker
and/or incur a loss of all or part of its margin deposits with the broker.
Similarly, in the event of the bankruptcy of the writer of an OTC option
purchased by 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 Investment Manager.
 
    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 (and the currencies in which they
are denominated) 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 (and the
currencies in which they are denominated). 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.
 
    As stated in the Prospectus, there may exist an imperfect correlation
between the price movements of futures contracts purchased by the Fund and the
movements in the prices of the securities (currencies) which are the subject of
the hedge. If participants in the futures market elect to close out their
contracts through offsetting transactions rather than meet margin deposit
requirements, distortions in the normal relationship between the debt securities
or currency markets and futures markets could result. Price distortions could
also result if investors in futures contracts opt to make or take delivery of
underlying securities rather than engage in closing transactions due to the
resultant reduction in the liquidity of the futures market. In addition, due to
the fact that, from the point of view of speculators, the deposit requirements
in the futures markets are less onerous than margin requirements in the cash
market, increased participation by speculators in the futures market could cause
temporary price distortions. Due to the possibility of price distortions 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 by the Investment Manager may still not result
in a successful hedging transaction.
 
    As stated in the Prospectus, 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
 
                                       25
<PAGE>
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 (currencies) at a time when it may be disadvantageous to do so.
 
    The extent to which the Fund may enter into transactions involving futures
contracts and options thereon 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).
 
    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 (currencies).
 
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. A repurchase agreement may be
viewed as a type of secured lending by the Fund which typically involves the
acquisition by the Fund of government 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 full
value of the collateral, as specified in the agreement, does not decrease below
the repurchase price plus accrued interest. If such decrease occurs, additional
collateral will be requested from the counterparty and will be added to the
account to maintain full collateralization. In the event the original seller
defaults on its obligations to repurchase, as a result of its bankruptcy or
otherwise, the Fund will seek to sell the collateral, which action could involve
costs or delays. In such case, the Fund's ability to dispose of the collateral
to recover its investment may be restricted or delayed.
 
    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 and may exceed one year.
 
    While repurchase agreements involve certain risks not associated with direct
investments in debt securities, the Fund follows procedures designed to minimize
such risks. Repurchase agreements will be transacted only with large,
well-capitalized and well-established financial institutions whose financial
condition will be continuously monitored by the Investment Manager subject to
procedures established by the Trustees. The procedures also require that the
collateral underlying the agreement be specified. The Fund does not presently
intend to enter into repurchase agreements so that more than 5% of the Fund's
net assets are subject to such agreements.
 
REVERSE REPURCHASE AGREEMENTS
 
    The Fund may also use reverse repurchase agreements for purposes of meeting
redemptions or 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.
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. Opportunities
to achieve this advantage may not always be available, and the Fund intends to
use the reverse repurchase technique only when it will be to its
 
                                       26
<PAGE>
advantage to do so. The Fund will establish a segregated account with its
custodian bank in which it will maintain cash or cash equivalents or other
liquid portfolio securities (i.e. U.S. Government securities) equal in value to
its obligations in respect of reverse repurchase agreements. Reverse repurchase
agreements are considered borrowings by the Fund and, in accordance with legal
requirements, the Fund will maintain an asset coverage (including the proceeds)
of at least 300% with respect to all reverse repurchase agreements. Reverse
repurchase agreements may not exceed 10% of the Fund's total assets.
 
WHEN-ISSUED AND DELAYED DELIVERY SECURITIES AND FORWARD COMMITMENTS
 
    As discussed in the Prospectus, 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 are subject to market
fluctuation and no interest accrues to the purchaser during this period. 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 securities on a
when-issued or delayed delivery basis, the Fund will record the transaction and
thereafter reflect the value, each day, of such security in determining the net
asset value of the Fund. At the time of delivery of the securities, the value
may be more or less than the purchase 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 for such when-issued or delayed delivery
securities; 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. The Investment
Manager and the Trustees do not believe that the Fund's net asset value or
income will be adversely affected by its purchase of securities on such basis.
 
WHEN, AS AND IF ISSUED SECURITIES
 
    As discussed in the Prospectus, 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 Investment Manager 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. The value of the Fund's commitments to
purchase the securities of any one issuer, together with the value of all
securities of such issuer owned by the Fund, may not exceed 5% of the value of
the Fund's total assets at the time the initial commitment to purchase such
securities is made (see "Investment Restrictions"). Subject to the foregoing
restrictions, 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 volatility of
its net asset value. The Investment Manager and the Trustees do not believe that
the net asset value of the Fund will be adversely affected by its purchase of
securities on such basis. 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.
 
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
 
                                       27
<PAGE>
Fund (subject to notice provisions described below), and are at all times
secured by cash or appropriate high-grade debt obligations, which are maintained
in a segregated account pursuant to applicable regulations and that are at least
equal to 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 days' 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 Investment Manager 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. The Fund has not
to date lent any of its portfolio securities.
 
PORTFOLIO TRADING
 
    It is anticipated that the Fund's portfolio turnover rate will not exceed
300% in any one year. A 300% turnover rate would occur, for example, if 300% 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.
 
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.
 
    The Fund may not:
 
         1.   Invest in securities of any issuer if, to the knowledge of the
    Fund, any officer or trustee of the Fund or any officer or director of the
    Investment Manager owns more than 1/2 of 1% of the outstanding securities of
    such issuer, and such officers, trustees and directors who own more than 1/2
    of 1% own in the aggregate more than 5% of the outstanding securities of
    such issuers.
 
         2.   Purchase or sell real estate or interests therein, although the
    Fund may purchase securities of issuers which engage in real estate
    operations and securities secured by real estate or interests therein.
 
         3.   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.
 
                                       28
<PAGE>
         4.   Purchase securities of other investment companies, except in
    connection with a merger, consolidation, reorganization or acquisition of
    assets. However, the Fund may invest up to 10% of the value of its total
    assets in the securities of foreign investment companies, but only under
    circumstances where purchase of the securities of foreign investment
    companies would secure entry to national markets which are otherwise not
    open to the Fund for investment or where the security is issued by a foreign
    bank which is deemed to be an investment company under U.S. securities laws
    and/or regulations.
 
        The Fund anticipates that it will incur any indirect expenses incurred
    through investment in a foreign investment company, such as the payment of a
    management fee. Furthermore, it should be noted that foreign investment
    companies are not subject to the U.S. securities laws and may be subject to
    fewer or less stringent regulations than U.S. investment companies.
 
         5.   Borrow money (except insofar as the Fund may be deemed to have
    borrowed by entrance into a reverse repurchase agreement up to an amount not
    exceeding 10% of the Fund's total assets), except that the Fund 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).
 
         6.   Pledge its assets or assign or otherwise encumber them except to
    secure borrowings effected within the limitations set forth in restriction
    (5). For the purpose of this restriction, collateral arrangements with
    respect to the writing of options and collateral arrangements with respect
    to initial or variation margin for futures are not deemed to be pledges of
    assets.
 
         7.   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 or reverse repurchase agreement; (b) purchasing
    any securities on a when-issued or delayed delivery basis; (c) purchasing or
    selling futures contracts, forward foreign exchange contracts or options;
    (d) borrowing money in accordance with restrictions described above; or (e)
    lending portfolio securities.
 
         8.   Make loans of money or securities, except: (a) by the purchase of
    publicly distributed debt obligations in which the Fund may invest
    consistent with its investment objectives and policies; (b) by investment in
    repurchase or reverse repurchase agreements; or (c) by lending its portfolio
    securities.
 
         9.   Make short sales of securities.
 
        10.   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 or related options thereon is not considered the purchase
    of a security on margin.
 
        11.   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.
 
        12.   Invest for the purpose of exercising control or management of any
    other issuer.
 
    If 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.
 
    Notwithstanding any other investment policy or restriction, the Fund may
seek to achieve its investment objectives by investing all or substantially all
of its assets in another investment company having substantially the same
investment objectives and policies as the Fund.

PORTFOLIO TRANSACTIONS AND BROKERAGE
- --------------------------------------------------------------------------------
 
   
    Subject to the general supervision of the Board of Trustees, the Investment
Manager 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. The Fund expects that the primary market for the securities in
which it intends to invest will generally be the over-the-counter market. 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. The
Fund expects that securities will 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. Options and 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 October 31, 1995, 1996 and 1997, the
Fund paid a total of $63,973, $53,726 and $18,640, respectively, in brokerage
commissions.
    
 
    The Investment Manager currently serves as investment manager to a number of
clients, including other investment companies, and may in the future act as
investment manager or adviser to others. It is the practice of the Investment
Manager 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, various
factors may be considered, including 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. In the case of certain initial
and secondary public offerings, the Investment Manager may utilize a pro rata
allocation process based on the size of the Dean Witter Funds involved and the
number of shares available from the public offering.
 
    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 Investment Manager from obtaining a high quality of
brokerage and research services. In seeking to determine the reasonableness of
brokerage commissions paid in any transaction, the Investment Manager 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.
 
    The Fund anticipates that certain of its transactions involving foreign
securities will be effected on securities exchanges. Fixed commissions on such
transactions are generally higher than negotiated commissions on domestic
transactions. There is also generally less government supervision and regulation
of foreign securities exchanges and brokers than in the United States.
 
    In seeking to implement the Fund's policies, the Investment Manager effects
transactions with those brokers and dealers who the Investment Manager believes
provide the most favorable prices and are capable of providing efficient
executions. If the Investment Manager 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 Investment Manager. Such services
may include, but are not limited to, any one or more of the following:
information as to the availability of securities for purchase or sale;
statistical or factual
 
                                       30
<PAGE>
   
information or opinions pertaining to investment; wire services; and appraisals
or evaluations of portfolio securities. During the fiscal year ended October 31,
1997, the Fund did not direct the payment of any brokerage commissions because
of research services provided.
    
 
    The information and services received by the Investment Manager from brokers
and dealers may be of benefit to the Investment Manager in the management of
accounts of some of its other clients and may not in all cases benefit the Fund
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 Investment Manager and thereby reduce its expenses,
it is of indeterminable value and the management fee paid to the Investment
Manager is not reduced by any amount that may be attributable to the value of
such services.
 
   
    Pursuant to an order of the Securities and Exchange Commission, the Fund may
effect principal transactions in certain money market instruments with DWR. The
Fund will limit its transactions with DWR to U.S. Government and Government
Agency Securities, Bank Money Instruments (i.e., Certificates of Deposit and
Bankers' Acceptances) and Commercial Paper. Such transactions will be effected
with DWR only when the price available from DWR is better than that available
from other dealers. During the fiscal years ended October 31, 1995, 1996 and
1997, the Fund did not effect any principal transactions with DWR.
    
 
   
    Consistent with the policy described above, brokerage transactions in
securities listed on exchanges or admitted to unlisted trading privileges may be
effected through DWR, Morgan Stanley & Co. Incorporated 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 DWR and Morgan Stanley & Co. Incorporated 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 the 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 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 an
affiliated broker or dealer are consistent with the foregoing standard. During
the fiscal years ended October 31, 1995, 1996 and 1997, the Fund did not effect
any securities transactions with or through an affiliated broker or dealer.
    
 
   
    During the fiscal year ended October 31, 1997, the Fund did not acquire any
securities of the ten brokers who executed the largest dollar amounts of the
Fund's portfolio transactions or of the ten dealers who executed the largest
dollar amounts of principal transactions with the Fund during the period, or
securities of the parents of those broker-dealers.
    
 
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. In addition, the Distributor may enter into selected
dealer agreements with other selected broker-dealers. The Distributor, a
Delaware corporation, is a wholly-owned subsidiary of MSDWD. The Trustees of the
Fund, including a majority of the Trustees who are not, and were not at the time
they voted, interested persons of the Fund, as defined in the Act (the
"Independent Trustees"), approved, at their meeting held on June 30, 1997, the
current Distribution Agreement appointing the Distributor as exclusive
distributor of the Fund's shares and providing for the Distributor to bear
distribution expenses not borne by the Fund. The current Distribution Agreement
is substantively identical to the Fund's previous distribution agreement in all
material respects, except for the dates of effectiveness. By its terms, the
Distribution Agreement has an initial term ending April 30, 1998, and will
remain in effect from year to year thereafter if approved by the Board.
 
                                       31
<PAGE>
    The Distributor bears all expenses incurred 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 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 and state securities laws and pays filing fees in
accordance with state securities laws. The Fund and the Distributor have agreed
to indemnify each other against certain liabilities, including liabilities under
the Securities Act 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
 
   
    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% and 0.85% of the average daily net assets of Class A and
Class C, respectively, and, with respect to Class B, 0.85% of the lesser of: (a)
the average daily aggregate gross sales of the Fund's Class B shares since the
inception of the Fund (not including reinvestments of dividends or capital gains
distributions), less the average daily aggregate net asset value of the Fund's
Class B shares redeemed since the Fund's inception upon which a contingent
deferred sales charge has been imposed or upon which such charge has been
waived, or (b) the average daily net assets of Class B. 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 $338,000, $109,685 and $67,575 in contingent deferred
sales charges from Class B for the fiscal years ended October 31, 1995, 1996 and
1997, respectively, and (b) approximately $0 in front-end sales charges from
Class A for the fiscal year ended October 31, 1997, none of which was retained
by the Distributor. No contingent deferred sales charges were received from
Class A or Class C for the fiscal year ended October 31, 1997.
    
 
    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
pursuant to the Plan equal to 0.20% of the average daily net assets of Class B
and 0.25% of the average daily net assets of Class C are currently each
characterized as a "service fee" under the Rules of the Association of the
National Association of Securities Dealers, Inc. (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 as 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 January 31, 1989, by
DWR as the then sole shareholder of the Fund on February 1, 1989 and by the
shareholders holding a majority, as defined in the Act, of the outstanding
voting securities of the Fund at a Special Meeting of Shareholders of the Fund
held on June 26, 1990.
 
    At their meeting held on October 30, 1992, the Trustees of the Fund,
including all of the Independent 12b-1 Trustees, approved certain amendments to
the Plan which took effect in January, 1993 and were designed to reflect the
fact that upon an internal reorganization the share distribution activities
theretofore performed for the Fund by DWR were assumed by the Distributor and
DWR's sales activities
 
                                       32
<PAGE>
are now being performed pursuant to the terms of a selected dealer agreement
between the Distributor and DWR. The amendments provide that payments under the
Plan will be made to the Distributor rather than to DWR as before the amendment,
and that the Distributor in turn is authorized to make payments to DWR, its
affiliates or other selected broker-dealers (or direct that the Fund pay such
entities directly). The Distributor is also authorized to retain part of such
fee as compensation for its own distribution-related expenses. At their meeting
held on April 28, 1993, the Trustees, including a majority of the Independent
12b-1 Trustees, approved certain technical amendments to the Plan in connection
with amendments adopted by the National Association of Securities Dealers, Inc.
to its Rules of the Association. At their meeting held on October 26, 1995, the
Trustees of the Fund, including all of 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 calendar quarter a written report provided
by the Distributor of the amounts expended by the Distributor under the Plan and
the purpose for which such expenditures were made. Class B shares of the Fund
accrued amounts payable to the Distributor under the Plan, during the fiscal
year ended October 31, 1997, of $881,250. This amount is equal to 0.85% of the
Fund's average daily net assets for the fiscal year and was calculated pursuant
to clause (b) of the compensation formula under the Plan. This amount is treated
by the Fund as an expense in the year it is accrued. For the fiscal period July
28 through October 31, 1997, Class A and Class C shares of the Fund accrued
payments under the Plan amounting to $169 and $165, respectively, which amounts
are equal to 0.25% and 0.85% of the average daily net assets of Class A and
Class C, 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 different 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 4.0% of the
amount sold (except as provided in the following sentence) and an annual
residual commission, currently a residual of up to 0.20% 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 employer-sponsored 401(k) and other
plans qualified under Section 401(a) of the Internal Revenue Code ("Qualified
Retirement Plans") for which Dean Witter Trust FSB ("DWT") serves as Trustee or
DWR's Retirement Plan Services serves as recordkeeper pursuant to a written
Recordkeeping Services Agreement, the Investment Manager 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 4.0% of the amount sold (except as
provided in the following sentence) and an annual residual commission, currently
a residual of up to 0.20% of the current value (not including reinvested
dividends or distributions) of the amount sold in all cases. In the case of
Class B shares purchased on or after July 28, 1997 by Qualified Retirement Plans
for which DWT serves as Trustee or DWR's Retirement Plan Services serves as
recordkeeper pursuant to a written Recordkeeping Services Agreement, DWR
compensates its account executives by paying them, from its own funds, a gross
sales credit of 3.0% of the amount sold.
    
 
                                       33
<PAGE>
    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 0.85% 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
InterCapital's mutual fund asset allocation program, the Investment Manager
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. The Investment Manager 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. 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.
    
 
    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 0.85%, 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.
 
   
    Each Class paid 100% of the amounts accrued under the Plan with respect to
that Class for the fiscal year ended October 31, 1997 to the Distributor. The
Distributor and DWR estimate that they have spent,
    
 
                                       34
<PAGE>
   
pursuant to the Plan, $36,026,861 on behalf of the Fund since the inception of
the Fund. It is estimated that this amount was spent in approximately the
following ways: (i) 7.13% ($2,568,946)--advertising and promotional expenses;
(ii) 0.59% ($212,634)--printing of prospectuses for distribution to other than
current shareholders; and (iii) 92.28% ($33,245,281)--other expenses, including
the gross sales credit and the carrying charge, of which 14.86% ($4,939,032)
represents carrying charges, 33.12% ($11,011,131) represents commission credits
to DWR branch offices for payments of commissions to account executives; and
52.02% ($17,295,118) represents overhead and other branch office
distribution-related expenses. These amounts represent amounts paid by Class B
only; there were no Class A or Class C shares outstanding on such date. The
amounts accrued by Class A and Class C for distribution during the fiscal period
July 28 through October 31, 1997 were for expenses that relate to compensation
of sales personnel and associated overhead expenses.
    
 
   
    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.
The Distributor has advised the Fund that in the case of Class B shares the
excess distribution expenses, including the carrying charge designed to
approximate the opportunity costs incurred by DWR which arise from it having
advanced monies without having received the amount of any sales charges imposed
at the time of sale of the Fund's Class B shares, totalled $8,370,199 as of
October 31, 1997. 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 financial
interest in the operation of the Plan except to the extent that the Distributor,
InterCapital, DWR, DWSC or certain of their employees may be deemed to have 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, 1989, and
will remain in effect from year to year thereafter, provided such continuance is
approved annually by a vote of the Independent 12b-1 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 continuation of the
Plan, the Trustees requested and received from the Distributor and reviewed all
the information which they 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 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. 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 by the shareholders of the
affected Class or Classes of the Fund, and all material amendments to 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
 
                                       35
<PAGE>
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 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 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 such price does not reflect their market value. 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 as of 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.
    
 
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 Dean Witter Funds that are multiple class funds
("Dean Witter Multi-Class Funds") or shares of other Dean Witter Funds sold with
a front-end sales charge 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 4.0% 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.
    
 
                                       36
<PAGE>
    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 Dean Witter Funds
held by the shareholder which were previously purchased at a price including a
front-end sales charge (including shares of the Fund and other Dean Witter Funds
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" (see "Shareholder Services--Exchange
Privilege") and the purchase of shares of other Dean Witter Funds will not be
included in determining whether the stated goal of a Letter of Intent has been
reached.
 
    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 Qualified Retirement 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 Qualified
Retirement 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 Dean Witter Fund (see "Shareholder
Services--Targeted Dividends"), plus (c) the current net asset value of shares
acquired in exchange for (i) shares of Dean Witter front-end sales charge funds,
or (ii) shares of other Dean Witter Funds for which shares of front-end sales
charge funds have been exchanged (see "Shareholder Services--Exchange
Privilege"), plus
    
 
                                       37
<PAGE>
(d) 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 Qualified Retirement
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 and/or shares
acquired in exchange for shares of Dean Witter front-end sales charge funds, or
for shares of other Dean Witter funds for which shares of front-end sales charge
funds have been exchanged. 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
Qualified Retirement Plans, three years) prior to the redemption and/or shares
purchased through reinvestment of dividends or distributions and/ or shares
acquired in the above-described exchanges 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 Qualified Retirement 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
- --------------------------------------------------------------------------------
 
    Upon the purchase of shares of the Fund, a Shareholder Investment Account is
opened for the investor on the books of the Fund and 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. 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.  As stated in the
Prospectus, all income 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, at the net asset value per share, in
shares of the applicable Class of the Fund (or in cash if the shareholder so
requests) 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 other selected
broker-dealer, and 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.
    
 
    TARGETED DIVIDENDS.-SM-  In states where it is legally permissible,
shareholders may also have all income dividends and capital gains distributions
automatically invested in shares of any Class of an open-end Dean Witter Fund
other than Dean Witter World Wide Income Trust or in another Class of Dean
Witter World Wide Income Trust. 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 Dean Witter Fund as of the close of
business on the payment date of the dividend or distribution and will begin to
earn dividends, if any, in the selected Dean Witter 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 Dean Witter Fund targeted to receive investments from dividends at the time
they enter the Targeted Dividends program. Investors should review the
prospectus of the targeted Dean Witter Fund before entering the program.
 
    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. Shares purchased through EasyInvest will be added to the shareholder's
existing account at the net asset value calculated
 
                                       39
<PAGE>
   
the same business day the transfer of funds is effected (subject to any
applicable sales charges). Shares of the Dean Witter money market funds redeemed
in connection with EasyInvest are redeemed on the business day preceding the
transfer of funds. 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 DIVIDENDS OR DISTRIBUTIONS RECEIVED IN CASH.  As discussed in
the Prospectus, any shareholder who receives a cash payment representing a
dividend or distribution may invest such dividend or distribution in shares of
the applicable Class at net asset value, 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 proceeds by the Transfer Agent.
 
    SYSTEMATIC WITHDRAWAL PLAN.  As discussed in the Prospectus, 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 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.
 
    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.
 
    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").
 
    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 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 "Redemptions and
Repurchases" in the Prospectus) at any time.
 
                                       40
<PAGE>
    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 Dean Witter World Wide Income Trust, and indicating the
selected Class, directly to the Fund's 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 or
purchase payment by the Transfer Agent. The shares so purchased will be credited
to the investor's account.
 
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
Dean Witter Multi-Class Fund without the imposition of any exchange fee. Shares
may also be exchanged for shares of any of the following funds: Dean Witter
Short-Term U.S. Treasury Trust, Dean Witter Limited Term Municipal Trust, Dean
Witter Short-Term Bond Fund, Dean Witter Intermediate Term U.S. Treasury Trust
and five Dean Witter Funds which are money market funds (the foregoing nine
funds are hereinafter referred to as the "Exchange Funds"). Class A shares may
also be exchanged for shares of Dean Witter Multi-State Municipal Series Trust
and Dean Witter Hawaii Municipal Trust, which are Dean Witter Funds sold with a
front-end sales charge ("FSC Funds"). Class B shares may also be exchanged for
shares of Dean Witter Global Short-Term Income Fund Inc. ("Global Short-Term"),
which is a Dean Witter Funds offered with a CDSC. 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.
    
 
    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 captions "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 Dean Witter
Multi-Class Fund or Global Short-Term 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 are redeemed out of
an Exchange Fund, they will be subject to a CDSC which would be based upon the
period of time the shareholder held shares in a Dean Witter Multi-Class Fund or
in Global Short-Term. However, in the case of shares exchanged for shares of an
Exchange Fund on or after April 23, 1990, 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
incurred on or after that date which are attributable to those shares.
Shareholders acquiring shares of an Exchange Fund or a money market fund
pursuant to this exchange privilege may exchange those shares back into a Dean
Witter Multi-Class Fund or Global Short-Term from the Exchange Fund, with no
CDSC being imposed on such exchange. The holding period previously frozen when
shares were first exchanged for shares of the Exchange Fund resumes on the last
day of the month in which shares of a Dean Witter Multi-Class Fund or Global
Short-Term 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 CDSC Fund, a Dean Witter Multi-Class Fund or in
    
 
                                       41
<PAGE>
   
Global Short-Term. In the case of exchanges of Class A shares which are subject
to a CDSC, the holding period also includes the time (calculated as described
above) the shareholder was invested in a FSC Fund.
    
 
   
    When shares initially purchased in a Dean Witter Multi-Class Fund or in
Global Short-Term are exchanged for shares of a Dean Witter Multi-Class Fund,
shares of Global Short-Term, shares of a FSC 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 upon the CDSC schedule
applicable to the shares) prior to the exchange, (ii) originally acquired
through reinvestment of dividends or distributions of the Fund or another Dean
Witter Fund and (iii) acquired in exchange for shares of FSC Funds, or for
shares of other Dean Witter Funds for which shares of FSC Funds have been
exchanged (all such shares called "Free Shares"), will be exchanged first. After
an exchange, all dividends earned on shares in an 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 (except that with respect to Class B shares, if
shares held for identical periods of time but subject to different CDSC
schedules are held in the same Exchange Privilege account, the shares of that
block that are subject to a lower CDSC rate will be exchanged prior to the
shares of that block that are subject to a higher CDSC rate). 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 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. 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 their discretion, accept initial investments
of as low as $1,000. The minimum initial
 
                                       42
<PAGE>
investment for the Exchange Privilege account of each Class is $10,000 for Dean
Witter Short-Term U.S. Treasury Trust, although that fund, at its discretion,
may accept initial purchases of as low as $5,000. The minimum initial investment
for the Exchange Privilege account of each Class is $5,000 for Dean Witter
Special Value Fund. The minimum initial investment for the Exchange Privilege
account of each Class for all other Dean Witter Funds for which the Exchange
Privilege is available is $1,000.) Upon exchange into an Exchange Fund, the
shares of that 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 those funds, including the check writing feature, will not be
available for funds held in that account.
 
    The Fund and each of the other Dean Witter 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 Dean Witter Funds for which
shares of the Fund have been exchanged, upon such notice as may be required by
applicable regulatory agencies (presently sixty days' prior written notice for
termination or material revision), provided that six months' prior written
notice of termination will be given to the shareholders who hold shares of an
Exchange Fund pursuant to the 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(s), policies and restrictions.
 
    For further information regarding the Exchange Privilege, shareholders
should contact their DWR or other selected broker-dealer account executive or
the Transfer Agent.
 
REDEMPTIONS AND REPURCHASES
- --------------------------------------------------------------------------------
 
    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" in the Prospectus) 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,
 
                                       43
<PAGE>
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 supplement to the prospectus
or a new prospectus.
 
    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 REDEEMED OR REPURCHASED.  As discussed in the Prospectus,
payment for shares of any Class 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 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 (including a certified or bank cashier's
check), payment of 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 proceeds 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 of 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, if the Fund makes an election, the shareholders would include
such undistributed gains in their income and shareholders will be able to claim
their share of the tax paid by the Fund as a credit against their individual
federal income tax.
 
    In computing net investment income, the Fund will not amortize premiums or
accrue discounts on fixed-income securities in the portfolio, except those
original issue discounts or acquisition discounts for which accrual is required
for federal income tax purposes. Additionally, with respect to market discounts
on bonds, a portion of any capital gain realized upon disposition may be
characterized as taxable ordinary income. Realized gains and losses on security
transactions are determined on the identified cost method.
 
    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.
 
   
    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 Treasury intends to issue regulations to
permit shareholders to take into account their proportionate share of the Fund's
capital gains distributions that will be subject to a reduced rate under the
Taxpayer Relief Act of 1997. The Taxpayer Relief Act reduced the maximum tax on
long-term capital gains from 28% to 20%; however, it also lengthened the
required holding period to obtain this lower rate from more than twelve months
to more than eighteen months. These lower rates do not apply to collectibles and
certain other assets. Additionally, the maximum capital gain rate for assets
that are held more than five years and that are acquired after December 31, 2000
is 18%.
    
 
   
    Any ordinary income dividends or capital gains distributions received by a
shareholder from any investment company will have the effect of reducing the net
asset value of the shareholder's shares in that company by the exact amount of
the dividend or capital gains distribution. Furthermore, capital gains
distributions and ordinary income 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 realized long-term capital
gains, such payment 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 taxable to the shareholder. Therefore, an investor should consider the tax
implications of purchasing Fund shares immediately prior to a dividend or
distribution record date.
    
 
   
    Any loss realized by shareholders upon a redemption of shares within six
months of the date of their purchase will be treated as a long-term capital loss
to the extent of any distributions of net long-term capital gains during the
six-month period.
    
 
   
    The Fund has qualified and intends to continue to qualify as a regulated
investment company under Subchapter M of the Internal Revenue Code of 1986 (the
"Code"). If so qualified, the Fund will not be subject to federal income tax on
its net investment income and capital gains, if any, realized during any fiscal
year in which it distributes such income and capital gains to its shareholders.
In addition, the Fund intends to distribute to its shareholders each calendar
year a sufficient amount of ordinary income and capital gains to avoid the
imposition of a 4% excise tax. Shareholders will normally have to pay federal
income taxes, and any state and/or local 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 received by the
shareholder in the prior year.
    
 
   
    Dividends, interest and capital gains received by the Fund may give rise to
withholding and other taxes imposed by foreign countries. Tax conventions
between certain countries and the United States
    
 
                                       45
<PAGE>
may reduce or eliminate such taxes. Investors may be entitled to claim United
States foreign tax credits with respect to such taxes, subject to certain
provisions and limitations contained in the Code. If more than 50% of the Fund's
total assets at the close of its fiscal year consist of securities of foreign
corporations, the Fund would be eligible and would determine whether or not to
file an election with the Internal Revenue Service pursuant to which
shareholders of the Fund will be required to include their respective pro rata
portions of such withholding taxes in their United States income tax returns as
gross income, treat such respective pro rata portions as taxes paid by them, and
deduct such respective pro rata portions in computing their taxable incomes or,
alternatively, use them as foreign tax credits against their United States
income taxes. If the Fund does elect to file the election with the Internal
Revenue Service, the Fund will report annually to its shareholders the amount
per share of such withholding.
 
    SPECIAL RULES FOR CERTAIN FOREIGN CURRENCY TRANSACTIONS.  In general, gains
from foreign currencies and from foreign currency options, foreign currency
futures and forward foreign exchange contracts relating to investments in stock,
securities or foreign currencies will be qualifying income for purposes of
determining whether the Fund qualifies as a regulated investment company. It is
currently unclear, however, who will be treated as the issuer of a foreign
currency instrument or how foreign currency options, futures, or forward foreign
currency contracts will be valued for purposes of the regulated investment
company diversification requirements applicable to the Fund. The Fund may
request a private letter ruling from the Internal Revenue Service on some or all
of these issues.
 
    Under Code Section 988, special rules are provided for certain transactions
in a foreign currency other than the taxpayer's functional currency (I.E.,
unless certain special rules apply, currencies other than the U.S. dollar). In
general, foreign currency gains or losses from forward contracts, from futures
contracts that are not "regulated futures contracts," and from unlisted options
will be treated as ordinary income or loss under Code Section 988. Also, certain
foreign exchange gains derived with respect to foreign fixed-income securities
are also subject to Section 988 treatment. In general, however, Code Section 988
gains or losses will increase or decrease the amount of the Fund's investment
company taxable income available to be distributed to shareholders as ordinary
income, rather than increasing or decreasing the amount of the Fund's net
capital gain. Additionally, if Code Section 988 losses exceed other investment
company taxable income during a taxable year, the Fund would not be able to make
any ordinary dividend distributions.
 
   
    After the end of the calendar year, shareholders will be sent full
information on their dividends and capital gains distributions for tax purposes,
including information as to the portion taxable as ordinary income, the portion
taxable as long-term capital gains and the portion eligible for the dividends
received deduction. To avoid being subject to a 31% federal backup withholding
tax on taxable dividends, capital gains distributions and the proceeds of
redemptions and repurchases, shareholders' taxpayer identification numbers must
be furnished and certified as to their accuracy.
    
 
    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. Yield is calculated for any 30-day period as follows: the amount of
interest 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" of each Class. 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 shares
of the applicable Class 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 yields for the 30-day period ended October 31, 1997,
calculated pursuant to the formula described above, were 4.86%, 4.52%, 4.50%,
and 5.26% for Class A, Class B, Class C, and Class D, respectively.
    
 
                                       46
<PAGE>
   
    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 C 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 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 October 31,
1997 were -2.08%, 1.12% and 2.44% for Class A, Class C and Class D,
respectively.
    
 
   
    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 average annual returns of the Fund for the fiscal year ended
October 31, 1997, for the five years ended October 31, 1997 and for the period
March 30, 1989 (commencement of the Fund's operations) through October 31, 1997
were 2.21%, 7.08% and 7.07%, respectively.
    
 
   
    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,
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 on this calculation,
the average annual total returns of Class B for the fiscal year ended October
31, 1997, for the five years ended October 31, 1997 and for the period March 30,
1989 (commencement of operations) through October 31, 1997 were 7.05%, 7.38% and
7.07%, respectively.
    
 
   
    In addition, the Fund may compute its aggregate total return for each Class
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 upon the foregoing
calculation, the total return for Class B for the fiscal year ended October 31,
1997 was 7.05%, for the five years ended October 31, 1997 was 42.78%, and for
the period March 30, 1989 (commencement of operations) through October 31, 1997
was 79.87%. Based on the foregoing calculations, the total returns for Class A,
Class C and Class D for the period July 28 through October 31, 1997 were 2.27%,
2.12% and 2.44%, respectively.
    
 
    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 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
$9,575, $48,250 and $97,250 in the case of Class A (investments of $10,000,
$50,000 and $100,000 adjusted for the initial sales charge) or by $10,000,
$50,000 and $100,000 in the case of each
 
                                       47
<PAGE>
   
of Class B, Class C and Class D, as the case may be. Investments of $10,000,
$50,000 and $100,000 in each Class at inception of the Class would have grown
(declined) to the following amounts at October 31, 1997:

DESCRIPTION OF SHARES OF THE FUND
    
- --------------------------------------------------------------------------------
 
   
    The shareholders of the Fund are entitled to a full vote for each full share
held. All of the Trustees have been elected by the shareholders of the Fund,
most recently at a Special Meeting of Shareholders held on May 21, 1997. 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 under certain
circumstances to remove the Trustees. 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 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 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 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 Trust shall be of unlimited duration subject to the provisions in the
Declaration of Trust concerning termination by action of the shareholders.

DEAN WITTER WORLD WIDE INCOME TRUST
NOTES TO FINANCIAL STATEMENTS OCTOBER 31, 1997
 
1. ORGANIZATION AND ACCOUNTING POLICIES
 
Dean Witter World Wide Income Trust (the "Fund") is registered under the
Investment Company Act of 1940, as amended (the "Act"), as a non-diversified,
open-end management investment company. The Fund's primary investment objective
is to provide a high level of current income and, as a secondary objective,
seeks appreciation in the value of its assets. The Fund was organized as a
Massachusetts business trust on October 14, 1988 and commenced operations on
March 30, 1989. On July 28, 1997, the Fund commenced offering three classes of
shares, with the then current shares designated as 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
these estimates.
 
The following is a summary of significant accounting policies:
 
A. VALUATION OF INVESTMENTS -- (1) all 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; (2) futures contracts
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 it will be valued at fair value as determined by the
Trustees; (3) when market quotations are not readily available, including
circumstances under which it is determined by Dean Witter InterCapital Inc. (the
"Investment Manager") 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 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
 
                                       54
<PAGE>
DEAN WITTER WORLD WIDE INCOME TRUST
NOTES TO FINANCIAL STATEMENTS OCTOBER 31, 1997, CONTINUED
 
its staff, including review of broker-dealer market price quotations, if
available, in determining what it believes is the fair valuation of the
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.
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. FUTURES CONTRACTS -- A futures contract is an agreement between two parties
to buy and sell financial instruments at a set price on a future date. Upon
entering into such a contract, the Fund is required to pledge to the broker
cash, U.S. Government securities or other liquid portfolio securities equal to
the minimum initial margin requirements of the applicable futures exchange.
Pursuant to the contract, the Fund agrees to receive from or pay to the broker
an amount of cash equal to the daily fluctuation in the value of the contract
which is known as variation margin. Such receipts or payments are recorded by
the Fund as unrealized gains or losses. Upon closing of the contract, the Fund
realizes a gain or loss equal to the difference between the value of the
contract at the time it was opened and the value at the time it was closed.
 
E. FOREIGN CURRENCY TRANSLATION -- The books and records of the Fund are
maintained in U.S. dollars as follows: (1) the foreign currency market value of
investment securities, other assets and liabilities and forward foreign currency
contracts are translated at the exchange rates prevailing at the end of the
period; and (2) purchases, sales, income and expenses are translated at the
exchange rates prevailing on the respective dates of such transactions. The
resultant exchange gains and losses are included in the Statement of Operations
as realized and unrealized gain/loss on foreign exchange transactions. Pursuant
to U.S. Federal income tax regulations, certain foreign exchange gains/losses
included in realized and unrealized gain/loss are included in or are a reduction
of ordinary income for
 
                                       55
<PAGE>
DEAN WITTER WORLD WIDE INCOME TRUST
NOTES TO FINANCIAL STATEMENTS OCTOBER 31, 1997, CONTINUED
 
federal income tax purposes. The Fund does not isolate that portion of the
results of operations arising as a result of changes in the foreign exchange
rates from the changes in the market prices of the securities.
 
F. FORWARD FOREIGN CURRENCY CONTRACTS -- The Fund may enter into forward foreign
currency contracts which are valued daily at the appropriate exchange rates. The
resultant unrealized exchange gains and losses are included in the Statement of
Operations as unrealized foreign currency gain or loss. The Fund records
realized gains or losses on delivery of the currency or at the time the forward
contract is extinguished (compensated) by entering into a closing transaction
prior to delivery.
 
G. 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.
 
H. 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.
 
2. INVESTMENT MANAGEMENT AGREEMENT
 
Pursuant to an Investment Management Agreement with the Investment Manager the
Fund pays a management fee, accrued daily and payable monthly, by applying the
following annual rates to the net assets of the Fund determined as of the close
of each business day: 0.75% to the portion of daily net assets not exceeding
$250 million; 0.60% to the portion of daily net assets exceeding $250 million
but not exceeding $500 million; 0.50% to the portion of daily net assets
exceeding $500 million but not exceeding $750 million; 0.40% to the portion of
daily net assets exceeding $750 million but not exceeding $1 billion; and 0.30%
to the portion of daily net assets exceeding $1 billion.

NOTES TO FINANCIAL STATEMENTS OCTOBER 31, 1997, CONTINUED
 
Under the terms of the Agreement, in addition to managing the Fund's
investments, the Investment 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 Investment
Manager. The Investment Manager also bears the cost of telephone services, heat,
light, power and other utilities provided to the Fund.
 
3. PLAN OF DISTRIBUTION
 
Shares of the Fund are distributed by Dean Witter Distributors Inc. (the
"Distributor"), an affiliate of the Investment 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 - up to 0.25% of the
average daily net assets of Class A; (ii) Class B - 0.85% of the lesser of: (a)
the average daily aggregate gross sales of the Class B shares since inception of
the Fund (not including reinvestment of dividend or capital gain distributions)
less the average net asset value of the Class B shares redeemed since the Fund's
inception upon which a contingent deferred sales charge has been imposed or
waived; or (b) the average daily net assets of Class B; and (iii) Class C - up
to 0.85% 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 Investment 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 such excess amounts, including
carrying charges, totaled $8,370,199 at October 31, 1997.
 
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 0.85% 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 credit to account executives may be reimbursed in the subsequent
calendar year. For the period ended October 31, 1997, the distribution fee was
accrued for Class A shares and Class C shares at the annual rate of 0.25% and
0.85%, respectively.
 
The Distributor has informed the Fund that for the year ended October 31, 1997,
it received contingent deferred sales charges from certain redemptions of the
Fund's Class B shares $67,575. The respective shareholders pay such charges
which are not an expense of the Fund.
 
4. SECURITY TRANSACTIONS AND TRANSACTIONS WITH AFFILIATES
 
The cost of purchases and proceeds from sales of portfolio securities, excluding
short-term investments, for the year ended October 31, 1997 aggregated
$306,368,737 and $321,049,399, respectively. Included in the aforementioned are
purchases and sales of U.S. Government securities of $184,895,045 and
$143,030,418, respectively.
 
Dean Witter Trust FSB, an affiliate of the Investment Manager and Distributor,
is the Fund's transfer agent. At October 31, 1997, the Fund had transfer agent
fees and expenses payable of approximately $1,000.
 
The Fund has an unfunded noncontributory defined benefit pension plan covering
all independent Trustees of the Fund who will have served as independent
Trustees for at least five years at the time of retirement. Benefits under this
plan are based on years of service and compensation during the last five years
of service. Aggregate pension costs for the year ended October 31, 1997 included
in Trustees' fees and expenses in the Statement of Operations amounted to
$2,434. At October 31, 1997, the Fund had an accrued pension liability of
$48,664 which is included in accrued expenses in the Statement of Assets and

6. FEDERAL INCOME TAX STATUS
 
During the year ended October 31, 1997, the Fund utilized approximately $873,000
of its net capital loss carryover. At October 31, 1997, the Fund had a net
capital loss carryover of approximately $5,327,000 which will be available
through October 31, 2002 to offset future capital gains to the extent provided
by regulations.
 
As of October 31, 1997, the Fund had temporary book/tax differences primarily
attributable to the mark-to-market of open forward foreign currency exchange
contracts and compensated forward foreign currency exchange contracts and
permanent book/tax differences primarily attributable to foreign currency gains.
To reflect reclassifications arising from the permanent differences, accumulated
net realized loss was charged $1,590,042, paid-in-capital was credited $44,385
and accumulated undistributed net investment income was credited $1,634,427.

7. PURPOSES OF AND RISKS RELATING TO CERTAIN FINANCIAL INSTRUMENTS
 
The Fund may enter into forward foreign currency contracts ("forward contracts")
to facilitate settlement of foreign currency denominated portfolio transactions
or to manage its foreign currency exposure or to sell, for a fixed amount of
U.S. dollars or other currency, the amount of foreign currency approximating the
value of some or all of its holdings denominated in such foreign currency or 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 its holdings to
be hedged. Additionally, when the Investment Manager anticipates purchasing
securities at some time in the future, the Fund may enter into a forward
contract to purchase an amount of currency equal to some or all the value of the
anticipated purchase for a fixed amount of U.S. dollars or other currency.
 
To hedge against adverse interest rate, foreign currency and market risks, the
Fund may enter into written options on interest rate futures and interest rate
futures contracts ("derivative investments").
 
Forward contracts and derivative instruments involve elements of market risk in
excess of the amount reflected in the Statement of Assets and Liabilities. The
Fund bears the risk of an unfavorable change in the foreign exchange rates
underlying the forward contracts. Risks may also arise upon entering into these
contracts from the potential inability of the counterparties to meet the terms
of their contracts.
 
At October 31, 1997, there were outstanding forward contracts used to facilitate
settlement of foreign currency denominated portfolio transactions and to manage
foreign currency exposure.

DEAN WITTER WORLD WIDE INCOME TRUST
REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE SHAREHOLDERS AND TRUSTEES
OF DEAN WITTER WORLD WIDE INCOME TRUST
 
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 Dean Witter World Wide Income Trust
(the "Fund") at October 31, 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 October
31, 1997 by correspondence with the custodian and brokers, provide a reasonable
basis for the opinion expressed above.

RATINGS
 
MOODY'S INVESTORS SERVICE INC. ("MOODY'S")
 
                                  BOND RATINGS
 
<TABLE>
<S>        <C>
Aaa        Bonds which are rated Aaa are judged to be of the best quality. They carry the
           smallest degree of investment risk and are generally referred to as "gilt edge."
           Interest payments are protected by a large or by an exceptionally stable margin and
           principal is secure. While the various protective elements are likely to change,
           such changes as can be visualized are most unlikely to impair the fundamentally
           strong position of such issues.
 
Aa         Bonds which are rated Aa are judged to be of high quality by all standards.
           Together with the Aaa group they comprise what are generally known as high grade
           bonds. They are rated lower than the best bonds because margins of protection may
           not be as large as in Aaa securities or fluctuation of protective elements may be
           of greater amplitude or there may be other elements present which make the
           long-term risks appear somewhat larger than in Aaa securities.
 
A          Bonds which are rated A possess many favorable investment attributes and are to be
           considered as upper medium grade obligations. Factors giving security to principal
           and interest are considered adequate, but elements may be present which suggest a
           susceptibility to impairment sometime in the future.
 
Baa        Bonds which are rated Baa are considered as medium grade obligations; i.e., they
           are neither highly protected nor poorly secured. Interest payments and principal
           security appear adequate for the present but certain protective elements may be
           lacking or may be characteristically unreliable over any great length of time. Such
           bonds lack outstanding investment characteristics and in fact have speculative
           characteristics as well.
 
           Bonds rated Aaa, Aa, A and Baa are considered investment grade bonds.
 
Ba         Bonds which are rated Ba are judged to have speculative elements; their future
           cannot be considered as well assured. Often the protection of interest and
           principal payments may be very moderate, and therefore not well safeguarded during
           both good and bad times over the future. Uncertainty of position characterizes
           bonds in this class.
 
B          Bonds which are rated B generally lack characteristics of desirable investments.
           Assurance of interest and principal payments or of maintenance of other terms of
           the contract over any long period of time may be small.
 
Caa        Bonds which are rated Caa are of poor standing. Such issues may be in default or
           there may be present elements of danger with respect to principal or interest.
 
Ca         Bonds which are rated Ca represent obligations which are speculative in a high
           degree. Such issues are often in default or have other marked shortcomings.
 
C          Bonds which are rated C are the lowest rated class of bonds, and issues so rated
           can be regarded as having extremely poor prospects of ever attaining any real
           investment standing.
</TABLE>
 
    RATING REFINEMENTS: Moody's may apply numerical modifiers, 1, 2, and 3 in
each generic rating classification from Aa through B in its corporate and
municipal bond 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.

<PAGE>
                            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. 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 catagories.
 
STANDARD & POOR'S CORPORATION ("STANDARD & POOR'S")
 
                                  BOND RATINGS
 
    A Standard & Poor's bond 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 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        Debt rated AAA has the highest rating assigned by Standard & Poor's. Capacity to
           pay interest and repay principal is extremely strong.
 
AA         Debt rated AA has a very strong capacity to pay interest and repay principal and
           differs from the highest-rated issues only in small degree.
 
A          Debt rated A has 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 debt in higher-rated categories.
 
BBB        Debt rated BBB is regarded as having an adequate capacity to pay interest and repay
           principal. Whereas it normally exhibits adequate protection parameters, adverse
           economic conditions or changing circumstances are more likely to lead to a weakened
           capacity to pay interest and repay principal for debt in this category than for
           debt in higher-rated categories.
 
           Bonds rated AAA, AA, A and BBB are considered investment grade bonds.
 
BB         Debt rated BB has less near-term vulnerability to default than other speculative
           grade debt. However, it faces major ongoing uncertainties or exposure to adverse
           business, financial or economic conditions which could lead to inadequate capacity
           to meet timely interest and principal payment.
 
B          Debt rated B has a greater vulnerability to default but presently has the capacity
           to meet interest payments and principal repayments. Adverse business, financial or
           economic conditions would likely impair capacity or willingness to pay interest and
           repay principal.
</TABLE>
 
                                       66
<PAGE>
<TABLE>
<S>        <C>
CCC        Debt rated CCC has a current identifiable vulnerability to default, and is
           dependent upon favorable business, financial and economic conditions to meet timely
           payments of interest and repayments of principal. In the event of adverse business,
           financial or economic conditions, it is not likely to have the capacity to pay
           interest and repay principal.
 
CC         The rating CC is typically applied to debt subordinated to senior debt which is
           assigned an actual or implied CCC rating.
 
C          The rating C is typically applied to debt subordinated to senior debt which is
           assigned an actual or implied CCC- debt rating.
 
CI         The rating CI is reserved for income bonds on which no interest is being paid.
 
D          Debt rated D is in default. The D rating is assigned on the day an interest or
           principal payment is missed.
 
NR         Indicates that no rating has been requested, that there is insufficient information
           on which to base a rating or that Standard & Poor's does not rate a particular type
           of obligation as a matter of policy.
</TABLE>
 
                            COMMERCIAL PAPER RATINGS
 
   
    Standard & 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 & 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. 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.


<PAGE>


     Pursuant to Section 5.2 of the Registrant's Declaration of Trust and
paragraph 8 of the Registrant's Investment Management Agreement, neither the
Investment Manager nor 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 Investment Manager, Registrant's
Trustees, and other registered investment management companies managed by the
Investment 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.

                         DEAN WITTER WORLD WIDE INCOME TRUST

                     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 Dean Witter World Wide Income Trust
dated October 13, 1988.

                                      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 twenty-five percent (25%) of all the votes
entitled to be cast at such meeting, except 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.


<PAGE>

     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
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 Section 32 of 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.

<PAGE>

     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 President and shall be called by the President
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
(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


                                          4
<PAGE>

            (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--

               (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 


                                          5
<PAGE>

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.

     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 records of the
proceedings of the Committee.

                                      ARTICLE VI

     SECTION 6.1. EXECUTIVE OFFICERS. The executive officers of the Trust shall
be a Chairman, a President, one or more Vice Presidents, a Secretary and a
Treasurer. The Chairman shall be selected from among the Trustees but none of

capacity. The executive officers of the Trust shall be elected annually by the
Trustees and each executive officer so elected shall hold office until his
successor is elected and has qualified.

     SECTION 6.2. OTHER OFFICERS AND AGENTS. The Trustees may also elect one or
more Assistant Vice Presidents, Assistant Secretaries and Assistant Treasurers

shall hold office until his successor is elected and has qualified. Any officer
or agent of the Trust may be removed by the Trustees whenever, in their
judgment, the best interests of the Trust will be served thereby, but such
removal shall be without prejudice to the contractual rights, if any, of the
person so removed.

     SECTION 6.4. COMPENSATION OF OFFICERS. The compensation of officers and
agents of the Trust shall be fixed by the Trustees, or by the President to the
extent provided by the Trustees with respect to officers appointed by the

                             DIVIDENDS AND DISTRIBUTIONS

     Subject to any applicable provisions of law and the Declaration, dividends
and distributions upon the Shares may be declared at such intervals as the
Trustees may determine, in cash, in securities or other property, or in Shares,
from any sources permitted by law, all as the Trustees shall from time to time
determine.

     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 Trust to avoid or
reduce liability for federal income taxes.

                                     ARTICLE VIII

                                CERTIFICATES OF SHARES

     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 recitals as may be
required by law. Where any certificate is signed by a Transfer Agent or by a
Registrar, the signature of such officers and the seal 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

                                      CUSTODIAN

     SECTION 9.1. APPOINTMENT AND DUTIES. The Trust shall at times employ a bank
or trust company having capital, surplus and undivided profits of at least five
million dollars ($5,000,000) as custodian with authority as its agent, but
subject to such restrictions, limitations and other requirements, if any, as may
be contained in these By-Laws and the 1940 Act:



                                          8
<PAGE>

          (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;

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.

                                      ARTICLE XI

                                    MISCELLANEOUS

     SECTION 11.1. LOCATION OF BOOKS AND RECORDS. The books and records of the
Trust may be kept outside the Commonwealth of Massachusetts at such place or
places as the Trustees may from time to time determine, except as otherwise
required by law.

     SECTION 11.2 RECORD DATE. The Trustees may fix in advance a date as the
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.

<PAGE>

     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.

     SECTION 11.4. FISCAL YEAR. The fiscal year of the Trust shall end on such
date as the Trustees may by resolution specify, and the Trustees may by
resolution change such date for future fiscal years at any time and from time to
time.

     SECTION 11.5. ORDERS FOR PAYMENT OF MONEY. All orders or instructions for
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 Dean Witter World Wide Income Trust,
dated October 13, 1988, a copy of which is on file in the office of the
Secretary of the Commonwealth of Massachusetts, provides that the name Dean
Witter World Wide Income Trust refers to the Trustees under the Declaration

    agreement between the Fund and DWTFSB, DWTFSB shall:
 
           (i) Receive for acceptance, orders for the purchase of Shares, and

       in the appropriate Shareholder account;
 
           (iii) Receive for acceptance redemption requests and redemption

       a record of the total number of Shares of the Fund which are authorized,
       based upon data provided to it by the Fund, and issued and outstanding.
       DWTFSB shall also provide to the Fund on a regular basis the total number
       of Shares that are authorized, issued and outstanding and shall notify

       statements for Shareholders and providing Shareholder account
       information;

       time to time by the Fund and DWTFSB.
 
        (d) DWTFSB shall provide such additional services and functions not
    specifically described herein as may be mutually agreed between DWTFSB and
