                 - 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

                 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 (i) 1.0% of
                 the lesser of: (a) the average daily net sales of the Fund's Class B shares since
                 implementation of the 12b-1 Plan on November 8, 1989 or (b) the average daily net assets
                 of Class B attributable to shares issued since implementation of the 12b-1 Plan, plus (ii)
                 0.25% of the average daily net assets of Class B attributable to shares issued prior to
                 implementation of the 12b-1 Plan. All shares of the Fund held prior to July 28, 1997
                 (other than shares which were purchased prior to November 8, 1989 (and, with respect to
                 such shares, certain shares acquired through reinvestment of dividends and capital gains
                 distributions) and the shares held by certain employee benefit plans established by Dean
                 Witter Reynolds Inc. and its affiliate, SPS Transaction Services, Inc.) have been
                 designated Class B shares. Shares which were purchased prior to November 8, 1989 (and,
                 with respect to such shares, certain shares acquired through reinvestment of dividends and
                 capital gains distributions) and shares held by those employee benefit plans prior to July
                 28, 1997 have been designated Class D shares. Shares held before May 1, 1997 that have
                 been designated Class B shares will convert to Class A shares in May, 2007. In all other
                 instances, Class B shares convert to Class A shares approximately ten years after the date
                 of the original purchase (see pages 18, 24 and 27).
 
                 - Class C shares are offered without a front-end sales charge, but will in most cases be
                 subject to a CDSC of 1.0% if redeemed within one year after purchase. The Fund is
                 authorized to reimburse the Distributor for specific expenses incurred in promoting the
                 distribution of the Fund's Class C shares and servicing shareholder accounts pursuant to
                 the Fund's 12b-1 Plan. Reimbursement may in no event exceed an amount equal to payments at
                 an annual rate of 1.0% of average daily net assets of the Class (see pages 18 and 27).
 
                 - Class D shares are offered only to investors meeting an initial investment minimum of $5
                 million and to certain other limited categories of investors. Class D shares are offered
                 without a front-end sales charge or CDSC and are not subject to any 12b-1 fee (see pages
                 18 and 27).
- ----------------------------------------------------------------------------------------------------------
Dividends        Dividends from net investment income are paid quarterly and distributions from net capital
and              gains, if any, are paid at least once per year. The Fund may, however, determine to retain
Capital Gains    all or part of any net long-term capital gains in any year for reinvestment. Dividends and
Distributions    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 30 and 34).

- ------------
(1) REDUCED FOR PURCHASES OF $25,000 AND OVER (SEE "PURCHASE OF FUND
    SHARES--INITIAL SALES CHARGE ALTERNATIVE--CLASS A SHARES").
 
(2) INVESTMENTS THAT ARE NOT SUBJECT TO ANY SALES CHARGE AT THE TIME OF PURCHASE
    ARE SUBJECT TO A CDSC OF 1.00% THAT WILL BE IMPOSED ON REDEMPTIONS MADE
    WITHIN ONE YEAR AFTER PURCHASE, EXCEPT FOR CERTAIN SPECIFIC CIRCUMSTANCES
    (SEE "PURCHASE OF FUND SHARES--INITIAL SALES CHARGE ALTERNATIVE--CLASS A
    SHARES").
 
(3) THE CDSC IS SCALED DOWN TO 1.00% DURING THE SIXTH YEAR, REACHING ZERO
    THEREAFTER.
 
(4) ONLY APPLICABLE TO REDEMPTIONS MADE WITHIN ONE YEAR AFTER PURCHASE (SEE
    "PURCHASE OF FUND SHARES-- LEVEL LOAD ALTERNATIVE--CLASS C SHARES").
 
(5) THE 12b-1 FEE IS ACCRUED DAILY AND PAYABLE MONTHLY. THE ENTIRE 12b-1 FEE
    PAYABLE BY CLASS A AND A PORTION OF THE 12b-1 FEE PAYABLE BY EACH OF CLASS B
    AND CLASS C EQUAL TO 0.25% OF THE AVERAGE DAILY NET ASSETS OF THE CLASS ARE
    CURRENTLY EACH CHARACTERIZED AS A SERVICE FEE WITHIN THE MEANING OF NATIONAL
    ASSOCIATION OF SECURITIES DEALERS, INC. ("NASD") GUIDELINES AND ARE PAYMENTS
    MADE FOR PERSONAL SERVICE AND/OR MAINTENANCE OF SHAREHOLDER ACCOUNTS. THE
    REMAINDER OF THE 12b-1 FEE, IF ANY, IS AN ASSET-BASED SALES CHARGE, AND IS A
    DISTRIBUTION FEE PAID TO THE DISTRIBUTOR TO COMPENSATE IT FOR THE SERVICES
    PROVIDED AND THE EXPENSES BORNE BY THE DISTRIBUTOR AND OTHERS IN THE
    DISTRIBUTION OF THE FUND'S SHARES (SEE "PURCHASE OF FUND SHARES--PLAN OF
    DISTRIBUTION").
 
(6) UPON CONVERSION OF CLASS B SHARES TO CLASS A SHARES, SUCH SHARES WILL BE
    SUBJECT TO THE LOWER 12b-1 FEE APPLICABLE TO CLASS A SHARES. NO SALES CHARGE
    IS IMPOSED AT THE TIME OF CONVERSION OF CLASS B SHARES TO CLASS A SHARES.
    CLASS C SHARES DO NOT HAVE A CONVERSION FEATURE AND, THEREFORE, ARE SUBJECT
    TO AN ONGOING 1.00% DISTRIBUTION FEE (SEE "PURCHASE OF FUND
    SHARES--ALTERNATIVE PURCHASE ARRANGEMENTS").
 
   
(7) THE 12b-1 FEE HAS BEEN RESTATED TO REFLECT WHAT THE FEE WOULD HAVE BEEN IF
    THE SHARES THAT WERE DESIGNATED CLASS D SHARES ON JULY 28, 1997 HAD NOT BEEN
    INCLUDED IN THE FUND DURING THE FISCAL YEAR ENDED JULY 31, 1997. THE ACTUAL
    12b-1 FEE WAS 0.89%.
    
 
   
(8) 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 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 Strategist Fund (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 August 5, 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 101 investment companies, thirty of which are
listed on the New York Stock Exchange, with combined assets of approximately
$95.9 billion as of August 31, 1997. The Investment Manager also manages and
advises portfolios of pension plans, other institutions and individuals which
aggregated approximately $3.6 billion at such date.
    
 
    The Fund has retained the Investment Manager to provide administrative
services, manage its business affairs, manage the investment of the Fund's
assets and determine the allocations 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 the annual rate
of 0.60% of the portion of the Fund's net assets not exceeding $500 million,
scaled down at various asset levels to 0.475% on the portion of the Fund's net
assets exceeding $1.5 billion. For the fiscal year ended July 31, 1997, the Fund
accrued total compensation to the Investment Manager amounting to 0.56% of the
Fund's average daily net assets and the total expenses of Class B amounted to
1.56% 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 OBJECTIVE AND POLICIES
- --------------------------------------------------------------------------------
 
    The investment objective of the Fund is to maximize the total return on its
investments. This is a fundamental policy and cannot be changed without the
approval of the Fund's shareholders. In seeking to achieve its objective, the
Fund actively allocates assets among the major asset categories of equity
securities, fixed-income securities and money market instruments. Total return
consists of current income (including dividends, interest and, in the case of
discounted instruments, discount accruals) and capital appreciation (including
realized and unrealized capital gains and losses). There can be
 
                                       10
<PAGE>
no assurance that the investment objective of the Fund will be achieved.
 
    The achievement of the Fund's investment objective depends upon the ability
of the Investment Manager to correctly assess the effects of economic and market
trends on different sectors of the market. The Investment Manager believes that
superior investment returns at lower risk are achievable by actively allocating
resources to the equity, debt and money market sectors of the market as opposed
to relying solely on just one market. At times, the equity market may hold a
higher potential return than the debt market and would warrant a higher asset
allocation. The reverse would be true when the bond market potential return is
higher. Short duration bonds and money market instruments can be used to soften
market declines when both bonds and equities are fully priced. Conserving
capital during declining markets can contribute to maximizing total return over
a longer period of time. In addition, the securities of companies within various
economic sectors may at times offer higher returns than other sectors and can
thus contribute to superior returns. Finally, the Investment Manager believes
that superior stock selection can also contribute to superior total return.
 
    To facilitate reallocation of the Fund's assets in accordance with the
Investment Manager's views as to shifts in the marketplace, the Investment
Manager employs transactions in futures contracts and options thereon. For
example, if the Investment Manager believes that a ten percent increase in that
portion of the Fund's assets invested in fixed-income securities and a
concomitant decrease in that portion of the Fund's assets invested in equity
securities is timely, the Fund might purchase interest rate futures, such as
Treasury bond futures, and sell stock index futures, such as the Standard &
Poor's Corporation ("S&P") 500 Stock Index futures, in equivalent amounts. The
utilization of futures transactions, rather than the purchase and sale of equity
and fixed-income securities, increases the speed and efficacy of the Fund's
asset reallocations. See below for a discussion of futures transactions.
 
    Within the equity sector, the Investment Manager actively allocates funds to
those economic sectors expected to benefit from major trends and to individual
stocks which are deemed to have superior investment potential. The Fund may
purchase equity securities (including convertible debt obligations and
convertible preferred stock) sold on the New York, American and other stock
exchanges and in the over-the-counter market. In addition, the Fund may purchase
and sell warrants and purchase and write listed and over-the-counter options on
individual stocks and stock indexes to hedge against adverse price movements in
its equity portfolio and to increase its total return through the receipt of
premium income. The Fund may also purchase and sell stock index futures and
options thereon to hedge against adverse price movements in its equity portfolio
and to facilitate asset reallocations into and out of the equity area.
 
    Within the fixed-income sector of the market, the Investment Manager seeks
to maximize the return on its investments by adjusting maturities and coupon
rates as well as by exploiting yield differentials among different types of
investment grade bonds. Fixed-income securities in which the Fund may invest are
short-term to intermediate (one to five year maturities) and intermediate to
long-term (greater than five year maturities) debt securities and preferred
stocks, including U.S. Government securities (securities issued or guaranteed as
to principal and interest by the United States or its agencies and
instrumentalities) and corporate securities which are rated at the time of
purchase Baa or better by Moody's Investors Service, Inc. ("Moody's") (while
bonds rated Baa by Moody's are considered investment grade, they have
speculative characteristics as well) or BBB or better by S&P, or which, if
unrated, are deemed to be of comparable quality by the Fund's Trustees (a
description of corporate bond ratings is contained in the Appendix to the
Statement of Additional Information). U.S. Government securities which may be
purchased
 
                                       11
<PAGE>
include zero coupon securities. In addition, the Fund may purchase and write
listed and over-the-counter options on fixed-income securities to hedge against
adverse price movements in its fixed-income portfolio and to increase its total
return through the receipt of premium income. The Fund may also purchase and
sell interest rate futures and options thereon to hedge against adverse price
movements in its fixed-income portfolio and to facilitate asset reallocations
into and out of the fixed-income area.
 
    Within the money market sector of the market, the Investment Manager seeks
to maximize returns by exploiting spreads among short-term instruments. The
money market portion of the Fund's portfolio will contain short-term (maturities
of up to thirteen months) fixed-income securities, issued by private and
governmental institutions. Such securities may include: U.S. Government
securities; bank obligations; Eurodollar certificates of deposit issued by
foreign branches of domestic banks; obligations of savings institutions; fully
insured certificates of deposit; and commercial paper rated within the two
highest grades by 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. For a discussion of the risks of investing in Eurodollar certificates
of deposit, see "Risk Considerations--Foreign Securities" below.
 
    FOREIGN SECURITIES.  The Fund may invest up to 20% of its total assets in
securities issued by foreign governments and other foreign issuers and in
foreign currency issues of domestic issuers, but not more than 10% of its total
assets in such securities, whether issued by a foreign or domestic issuer, which
are denominated in foreign currency. With regard to foreign fixed-income
securities, the Investment Manager believes that in many instances such
securities may provide higher yields than similar securities of domestic
issuers. For a discussion of the risks of investing in foreign securities, see
"Risk Considerations" below.
 
    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. For a discussion of the risks of investing in repurchase agreements,
see "Risk Considerations" below.
 
    PRIVATE PLACEMENTS.  The Fund may invest in securities which are subject to
restrictions on resale because they have not been registered under the
Securities Act of 1933, as amended (the "Securities Act"), or which are
otherwise not readily marketable. These securities are generally referred to as
private placements or restricted securities. The 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. For a discussion of the risks of
investing in private placements, see "Risk Considerations" below.
 
    INVESTMENT IN REAL ESTATE INVESTMENT TRUSTS. The Fund may invest in real
estate investment trusts, which pool investors' funds for investments primarily
in commercial real estate properties. Investment in real estate investment
trusts may be the most practical available means for the Fund to invest in the
real estate industry (the Fund is prohibited from investing in real estate
directly). As a shareholder in a real estate investment trust, the Fund would
bear its ratable share of the real estate investment trust's expenses, including
its advisory and administration
 
                                       12
<PAGE>
fees. At the same time the Fund would continue to pay its own investment
management fees and other expenses, as a result of which the Fund and its
shareholders in effect will be absorbing duplicate levels of fees with respect
to investments in real estate investment trusts.
 
    OPTIONS.  The Fund also may purchase and sell (write) call and put options
on debt and equity securities which are listed on Exchanges or are written in
over-the-counter transactions ("OTC options"). Listed options, which are
currently listed on several different Exchanges, 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.
 
    OTC OPTIONS.  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. The Fund will engage in OTC
option transactions only with primary U.S. Government securities dealers
recognized by the Federal Reserve Bank of New York.
 
    COVERED CALL WRITING.  The Fund is permitted to write covered call options
on portfolio securities, without limit, in order to aid it in achieving its
investment objective. As a writer of a call option, the Fund has the obligation,
upon notice of exercise of the option, to deliver the security underlying the
option (certain listed call options written by the Fund will be exercisable by
the purchaser only on a specific date). See "Options and Futures Transactions--
Covered Call Writing" in the Statement of Additional Information.
 
    COVERED PUT WRITING.  As a writer of covered put options, 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. The
Fund will write put options for two purposes: (1) to receive the premiums paid
by purchasers; and (2) when the Investment Manager wishes to purchase the
security underlying the option at a price lower than its current market price,
in which case it will write the covered put at an exercise price reflecting the
lower purchase price sought. See "Options and Futures Transactions--Covered Put
Writing" in the Statement of Additional Information.
 
    PURCHASING CALL AND PUT OPTIONS.  The Fund may invest up to 5% of its total
assets in the purchase of put and call options on securities and stock indexes.
The Fund may purchase call options only in order to close out a covered call
position. The Fund may purchase put options on securities which it holds (or has
the right to acquire) in its portfolio only to protect itself against a decline
in the value of the security. The Fund may also purchase put options to close
out written put positions in a manner similar to call option closing purchase
transactions. There are no other limits on the Fund's ability to purchase call
and put options.
 
    STOCK INDEX OPTIONS.  The Fund may purchase and write options on stock
indexes. Options on stock indexes are similar to options on stock except that,
rather than the right to take or make delivery of stock at a specified price, an
option on a stock index gives the holder the right to receive, upon exercise of
the option, an amount of cash if the closing level of the stock index upon which
the option is based is greater than, in the case of a call, or less than, in the
case of a put, the exercise price of the option. See "Stock Index Options" and
"Risks of Options on Indexes" in the Statement of Additional Information.
 
                                       13
<PAGE>
    FUTURES CONTRACTS.  The Fund may purchase and sell interest rate and stock
index futures contracts ("futures contracts") that are traded on U.S. commodity
exchanges on such underlying securities as U.S. Treasury bonds, notes, and bills
and GNMA Certificates ("interest rate futures") and such indexes as the S&P 500
Index and the New York Stock Exchange Composite Index ("stock index futures")
and the Moody's Investment-Grade Corporate Bond Index ("bond index futures"). As
a futures contract purchaser, the Fund incurs an obligation to take delivery of
a specified amount of the obligation underlying the contract at a specified time
in the future for a specified price. As a seller of a futures contract, the Fund
incurs an obligation to deliver the specified amount of the underlying
obligation at a specified time in return for an agreed upon price. The Fund will
purchase or sell interest rate futures contracts and bond index futures
contracts for the purpose of hedging its fixed-income portfolio (or anticipated
portfolio) securities against changes in prevailing interest rates. The Fund
will purchase or sell stock index futures contracts for the purpose of hedging
its equity portfolio (or anticipated portfolio) securities against changes in
their prices. As noted above, the Fund may also engage in futures transactions
to facilitate reallocation of the Fund's assets. The Fund also may purchase and
write call and put options on futures contracts and enter into closing
transactions with respect to such options to terminate an existing position. See
"Options and Futures Transactions--Futures Contracts" and "Options on Futures
Contracts" in the Statement of Additional Information.
 
    For a discussion of the risks of options and futures transactions, see "Risk
Considerations" below and "Options and Futures Transactions" in the Statement of
Additional Information.
                            ------------------------
 
    The Fund may purchase securities on a when-issued or delayed delivery basis,
may purchase or sell securities on a forward commitment basis, may purchase
securities on a "when, as and if issued" basis, may lend its portfolio
securities, and may enter into reverse repurchase agreements, as discussed under
"Risk Considerations" below.
 
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 level of income
payable to the investor will vary depending upon the market allocation
determined by the Investment Manager and with various determinants such as
interest rates.
 
    FOREIGN SECURITIES.  Foreign securities investments may be affected by
changes in currency rates or exchange control regulations, changes in
governmental administration or economic or monetary policy (in the United States
and abroad) or changed circumstances in dealings between nations. Fluctuations
in the relative rates of exchange between the currencies of different nations
will affect the value of the Fund's investments denominated in foreign currency.
Changes in foreign currency exchange rates relative to the U.S. dollar will
affect the U.S. dollar value of the Fund's assets denominated in that currency
and thereby impact upon the Fund's total return on such assets.
 
    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 Fund will incur costs in connection
with conversions between various currencies.
 
    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
 
                                       14
<PAGE>
foreign social, economic or political instability. Foreign companies are not
subject to the regulatory requirements of U.S. companies and, as such, there may
be less publicly available information about such companies. Moreover, foreign
companies are not subject to uniform accounting, auditing and financial
reporting standards and requirements comparable to those applicable to U.S.
companies. Finally, in the event of a default of any foreign debt obligations,
it may be more difficult for the Fund to obtain or enforce a judgment against
the issuers of such securities.
 
    Securities of foreign issuers may be less liquid than comparable securities
of U.S. issuers and, as such, their price changes may be more volatile.
Furthermore, foreign exchanges and broker-dealers are generally subject to less
government and exchange scrutiny and regulation than their American
counterparts. Brokerage commissions, dealer concessions and other transaction
costs may be higher on foreign markets than in the U.S. In addition, differences
in clearance and settlement procedures on foreign markets may occasion delays in
settlements of the Fund's trades effected in such markets. As such, the
inability to dispose of portfolio securities due to settlement delays could
result in losses to the Fund due to subsequent declines in value of such
securities and the inability of the Fund to make intended security purchases due
to settlement problems could result in a failure of the Fund to make potentially
advantageous investments. To the extent the Fund purchases Eurodollar
certificates of deposit issued by foreign branches of domestic United States
banks, consideration will be given to their domestic marketability, the lower
reserve requirements normally mandated for overseas banking operations, the
possible impact of interruptions in the flow of international currency
transactions and future international political and economic developments which
might adversely affect the payment of principal or interest.
 
    REPURCHASE AGREEMENTS.  While repurchase agreements involve certain risks
not associated with direct investments in debt securities, 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. In addition, the value of the collateral underlying the
repurchase agreement will be at least equal to the repurchase price, including
any accrued interest earned on the repurchase agreement. In the event of a
default or bankruptcy by a selling financial institution, the Fund will seek to
liquidate such collateral. However, the exercising of the Fund's right to
liquidate such collateral could involve certain costs or delays and, to the
extent that proceeds from any sale upon a default of the obligation to
repurchase were less than the repurchase price, the Fund could suffer a loss.
The Fund may not invest in repurchase agreements that do not mature within seven
days if any such investment, together with any other illiquid assets held by the
Fund, amounts to more than 10% of its total assets.
 
    PRIVATE PLACEMENTS.  Limitations on the resale of private placements 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. In the case of restricted securities
determined to be "liquid" pursuant to Rule 144A under the Securities Act, the
Fund's illiquidity could increase if qualified institutional buyers become
unavailable.
 
    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
 
                                       15
<PAGE>
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 the Fund's net asset value.
 
    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. Also, 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.
 
    The extent to which the Fund may enter into transactions involving options
and futures contracts may be limited by the Internal Revenue Code's requirements
for qualification as a regulated investment company and the Fund's intention to
qualify as such. See "Dividends, Distributions and Taxes."
 
    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 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 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. See the Statement of Additional Information for further
discussion of such risks.
 
    New futures contracts, options and other financial products and various
combinations thereof continue to be developed. The Fund may invest in any such
futures, options or products as may be developed, to the extent consistent with
its investment objective and applicable regulatory requirements.
 
    REVERSE REPURCHASE AGREEMENTS.  The Fund may enter into reverse repurchase
agreements, which 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
 
                                       16
<PAGE>
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 considered borrowings by the Fund
and for purposes other than meeting redemptions may not exceed 5% of the Fund's
total assets.
 
    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 money market
instruments, which are maintained in a segregated account pursuant to applicable
regulations and that are equal to at least the market value, determined daily,
of the loaned securities. 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.
 
    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 (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 (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.
 
    For additional risk disclosure, please refer to the "Investment Objective
and Policies" section of the Prospectus and to the "Investment Practices and
Policies" section of the Statement of Additional Information.
 
PORTFOLIO MANAGEMENT
 
   
    The Fund's portfolio is actively managed by the Investment Manager with a
view to achieving the Fund's investment objective. 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") and other broker-dealer affiliates of InterCapital, the
views of others regarding economic developments and interest rate trends, and
the Investment Manager's own analysis of factors it deems relevant. The Fund's
portfolio is managed within InterCapital's Growth and Income Group, which
manages twenty-three funds and fund portfolios, with approximately $27.8 billion
in assets as of August 31, 1997. Mark Bavoso, Senior Vice President of
InterCapital and a member of InterCapital's Growth and Income Group, has been
the primary portfolio manager of the Fund since January, 1994, and has been a
portfolio manager at InterCapital for over five years.
    
 
    Orders for transactions in other portfolio securities and commodities are
placed for the Fund with a number of brokers and dealers, including DWR and
other broker-dealer affiliates of InterCapital. Pursuant to an order of the
Securities and Exchange Commission, the Fund may effect principal transactions
in certain money market instruments with DWR. In addition, the Fund may incur
brokerage commissions on transactions conducted through DWR and other brokers
and dealers that are affiliates of InterCapital.
 
    It is not anticipated that the portfolio trading engaged in by the Fund will
result in its portfolio turnover rate exceeding 200% in any one year. The
 
                                       17
<PAGE>
Fund will incur underwriting discount costs (on underwritten securities) and
brokerage costs commensurate with its portfolio turnover rate, and thus a higher
level (over 100%) of portfolio transactions will increase the Fund's overall
brokerage expenses. See "Dividends, Distributions and Taxes" for a discussion of
the tax implications of the Fund's transactions. A more extensive discussion of
the Fund's portfolio brokerage policies is set forth in the Statement of
Additional Information.
 
    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.
 
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. This restriction does not apply to obligations
issued or guaranteed by the United States Government or its agencies or
instrumentalities.
 
   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 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.
 
    Notwithstanding any other investment policy or restriction, the Fund may
seek to achieve its investment objective by investing all or substantially all
of its assets in another investment company having substantially the same
investment objective and policies as the Fund.
 
PURCHASE OF FUND SHARES
- --------------------------------------------------------------------------------
 
GENERAL
 
    The Fund offers each class of its 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 who have entered into
 
                                       18
<PAGE>
selected dealer agreements with the Distributor ("Selected Broker-Dealers"). The
principal executive office of the Distributor is located at Two World Trade
Center, New York, New York 10048.
 
    The Fund offers four classes of shares (each, a "Class"). Class A shares are
sold to investors with an initial sales charge that declines to zero for larger
purchases; however, Class A shares sold without an initial sales charge are
subject to a contingent deferred sales charge ("CDSC") of 1.0% if redeemed
within one year of purchase, except for certain specific circumstances. Class B
shares are sold without an initial sales charge but are subject to a CDSC
(scaled down from 5.0% to 1.0%) payable upon most redemptions within six years
after purchase. (Class B shares purchased by certain qualified
employer-sponsored benefit plans are subject to a CDSC scaled down from 2.0% to
1.0% if redeemed within three years after purchase.) Class C shares are sold
without an initial sales charge but are subject to a CDSC of 1.0% on most
redemptions made within one year after purchase. Class D shares are sold without
an initial sales charge or CDSC and are available only to investors meeting an
initial investment minimum of $5 million, and to certain other limited
categories of investors. At the discretion of the Board of Trustees of the Fund,
Class A shares may be sold to categories of investors in addition to those set
forth in this prospectus at net asset value without a front-end sales charge,
and Class D shares may be sold to certain other categories of investors, in each
case as may be described in the then current prospectus of the Fund. See
"Alternative Purchase Arrangements-- Selecting a Particular Class" for a
discussion of factors to consider in selecting which Class of shares to
purchase.
 
   
    The minimum initial purchase is $1,000 for each Class of shares, although
Class D shares are only available to persons investing $5 million or more and to
certain other limited categories of investors. For the purpose of meeting the
minimum $5 million initial investment for Class D shares, and subject to the
$1,000 minimum initial investment for each Class of the Fund, an investor's
existing holdings of Class A shares 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 Strategist Fund, directly to Dean Witter
Trust FSB (the "Transfer Agent" or "DWT") at P.O. Box 1040, Jersey City, NJ
07303 or by contacting an account executive of DWR or other Selected
Broker-Dealer. When purchasing shares of the Fund, investors must specify
whether the purchase is for Class A, Class B, Class C or Class D shares. If no
Class is specified, the Transfer Agent will not process the transaction until
the proper Class is identified. The minimum initial purchase in the case of
investments through EasyInvest-SM-, an automatic purchase plan (see "Shareholder
Services"), is $100, provided that the schedule of automatic investments will
result in investments totalling at least $1,000 within the first twelve months.
In the case of investments pursuant to Systematic Payroll Deduction Plans
(including Individual Retirement Plans), the Fund, in its discretion, may accept
investments without regard to any minimum amounts which would otherwise be
required, if the Fund has reason to believe that additional investments will
increase the investment in each account 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
 
                                       19
<PAGE>
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 at the time of their sale by the Distributor or any
of its affiliates and/or the Selected Broker-Dealer. In addition, some sales
personnel of the Selected Broker-Dealer will receive various types of non-cash
compensation as special sales incentives, including trips, educational and/or
business seminars and merchandise. The Fund and the Distributor reserve the
right to reject any purchase 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 5.25%. The initial sales charge is reduced for certain
purchases. Investments of $1 million or more (and investments by certain other
limited categories of investors) are not subject to any sales charges at the
time of purchase but are subject to a CDSC of 1.0% on redemptions made within
one year after purchase, except for certain specific circumstances. Class A
shares are also subject to a 12b-1 fee of up to 0.25% of the average daily net
assets of the Class. See "Initial Sales Charge Alternative--Class A Shares."
 
    CLASS B SHARES.  Class B shares are offered at net asset value with no
initial sales charge but are subject to a CDSC (scaled down from 5.0% to 1.0%)
if redeemed within six years of purchase. (Class B shares purchased by certain
qualified employer-sponsored benefit plans are subject to a CDSC scaled down
from 2.0% to 1.0% if 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 (i) 1.0% of the lesser of: (a) the average daily aggregate gross
sales of the Fund's Class B shares since the implementation of the 12b-1 Plan on
November 8, 1989 (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 implementation of the 12b-1 Plan upon which a
CDSC has been imposed or waived, or (b) the average daily net assets of Class B
attributable to shares issued, net of related shares redeemed, since
implementation of the 12b-1 Plan, plus (ii) 0.25% of the average daily net
assets of Class B attributable to shares issued, net
 
                                       20
<PAGE>
of related shares redeemed, prior to implementation of the 12b-1 Plan. The Class
B shares' distribution fee will cause that Class to have higher expenses and pay
lower dividends than Class A or Class D shares.
 
    After approximately ten (10) years, Class B shares will convert
automatically to Class A shares of the Fund, based on the relative net asset
values of the shares of the two Classes on the conversion date. In addition, a
certain portion of Class B shares that have been acquired through the
reinvestment of dividends and distributions will be converted at that time. See
"Contingent Deferred Sales Charge Alternative--Class B Shares."
 
    CLASS C SHARES.  Class C shares are sold at net asset value with no initial
sales charge but are subject to a CDSC of 1.0% on redemptions made within one
year after purchase. This CDSC may be waived for certain redemptions. They are
subject to an annual 12b-1 fee of up to 1.0% of the average daily net assets of
the Class C shares. The Class C shares' distribution fee may cause that Class to
have higher expenses and pay lower dividends than Class A or Class D shares. See
"Level Load Alternative--Class C Shares."
 
    CLASS D SHARES.  Class D shares are available only to limited categories of
investors (see "No Load Alternative--Class D Shares" below). Class D shares are
sold at net asset value with no initial sales charge or CDSC. They are not
subject to any 12b-1 fees. See "No Load Alternative--Class D Shares."
 
    SELECTING A PARTICULAR CLASS.  In deciding which Class of Fund shares to
purchase, investors should consider the following factors, as well as any other
relevant facts and circumstances:
 
    The decision as to which Class of shares is more beneficial to an investor
depends on the amount and intended length of his or her investment. Investors
who prefer an initial sales charge alternative may elect to purchase Class A
shares. Investors qualifying for significantly reduced or, in the case of
purchases of $1 million or more, no initial sales charges may find Class A
shares particularly attractive because similar sales charge reductions are not
available with respect to Class B or Class C shares. Moreover, Class A shares
are subject to lower ongoing expenses than are Class B or Class C shares over
the term of the investment. As an alternative, Class B and Class C shares are
sold without any initial sales charge so the entire purchase price is
immediately invested in the Fund. Any investment return on these additional
investment amounts may partially or wholly offset the higher annual expenses of
these Classes. Because the Fund's future return cannot be predicted, however,
there can be no assurance that this would be the case.
 
    Finally, investors should consider the effect of the CDSC period and any
conversion rights of the Classes in the context of their own investment time
frame. For example, although Class C shares are subject to a significantly lower
CDSC upon redemptions, they do not, unlike Class B shares, convert into Class A
shares after approximately ten years, and, therefore, are subject to an ongoing
12b-1 fee of 1.0% (rather than the 0.25% fee applicable to Class A shares) for
an indefinite period of time. Thus, Class B shares may be more attractive than
Class C shares to investors with longer term investment outlooks. Other
investors, however, may elect to purchase Class C shares if, for example, they
determine that they do not wish to be subject to a front-end sales charge and
they are uncertain as to the length of time they intend to hold their shares.
 
    For the purpose of meeting the $5 million minimum investment amount for
Class D shares, holdings of Class A shares in all 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
 
                                       21
<PAGE>
sales charges applicable to each Class provide for the financing of the
distribution of shares of that Class.
 
    Set forth below is a chart comparing the sales charge, 12b-1 fees and
conversion options applicable to each Class of shares:

each Class of shares and "Determination of Net Asset Value," "Dividends,
Distributions and Taxes" and "Shareholder Services--Exchange Privilege" for
other differences between the Classes of shares.
 
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.
 
                                       22
<PAGE>
    The above schedule of sales charges is applicable to purchases in a single
transaction by, among others: (a) an individual; (b) an individual, his or her
spouse and their children under the age of 21 purchasing shares for his, her or
their own accounts; (c) a trustee or other fiduciary purchasing shares for a
single trust estate or a single fiduciary account; (d) a pension, profit-sharing
or other employee benefit plan qualified or non-qualified under Section 401 of
the Internal Revenue Code; (e) tax-exempt organizations enumerated in Section
501(c)(3) or (13) of the Internal Revenue Code; (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 equal to at least $5 million, such
investor is eligible to purchase Class D shares subject to the $1,000 minimum
initial investment requirement of that Class of the Fund. See "No Load
Alternative-- Class D Shares" below.
 
    The Distributor must be notified by DWR or a Selected Broker-Dealer or the
shareholder at the time a purchase order is placed that the purchase qualifies
for the reduced charge under the Right of Accumulation. Similar notification
must be made in writing by the dealer or shareholder when such an order is
placed by mail. The reduced sales charge will not be granted if: (a) such
notification is not furnished at the time of the order; or (b) a review of the
records of the Selected Broker-Dealer or the Transfer Agent fails to confirm the
investor's represented holdings.
 
    LETTER OF INTENT.  The foregoing schedule of reduced sales charges will also
be available to investors who enter into a written Letter of Intent providing
for the purchase, within a thirteen-month period, of Class A shares of the Fund
from DWR or other Selected Broker-Dealers. The cost of Class A shares of the
Fund or 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.
 
                                       23
<PAGE>
    ADDITIONAL NET ASSET VALUE PURCHASE OPTIONS. In addition to investments of
$1 million or more, Class A shares also may be purchased at net asset value by
the following:
 
   
   (1) trusts for which DWT (an affiliate of the Investment Manager) provides
discretionary trustee services;
    
 
   
   (2) persons participating in a fee-based program approved by the Distributor,
pursuant to which such persons pay an asset based fee for services in the nature
of investment advisory or administrative services (such investments are subject
to all of the terms and conditions of such programs, which may include
termination fees, mandatory redemption upon termination and such other
circumstances as specified in the programs' agreements, and restrictions on
transferability of Fund shares);
    
 
   
   (3) retirement plans qualified under Section 401(k) of the Internal Revenue
Code ("401(k) plans") and other employer-sponsored plans qualified under Section
401(a) of the Internal Revenue Code with at least 200 eligible employees and for
which DWT serves as Trustee or the 401(k) Support Services Group of DWR serves
as recordkeeper;
    
 
   
   (4) 401(k) plans and other employer-sponsored plans qualified under Section
401(a) of the Internal Revenue Code for which DWT serves as Trustee or the
401(k) Support Services Group of DWR serves as recordkeeper whose Class B shares
have converted to Class A shares, regardless of the plan's asset size or number
of eligible employees;
    
 
   (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 employer-sponsored benefit
plans, three years) preceding the redemption. In addition, Class B shares are
subject to an annual 12b-1 fee of (i) 1.0% of the lesser of: (a) the average
daily aggregate gross sales of the Fund's Class B shares since the
implementation of the 12b-1 Plan on November 8, 1989 (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
implementation of the 12b-1 Plan upon which a CDSC has been imposed or waived,
or (b) the average daily net assets of Class B attributable to shares issued,
net of related shares redeemed, since implementation of the 12b-1 Plan, plus
(ii) 0.25% of the average daily net assets of Class B attributable to shares
issued, net of related shares redeemed, prior to implementation of the 12b-1
Plan.

    Except as noted below, Class B shares of the Fund which are held for six
years or more after purchase (calculated from the last day of the month in which
the shares were purchased) will not be subject to any CDSC upon redemption.
Shares redeemed earlier than six years after purchase may, however, be subject
to a CDSC which will be a percentage of the dollar amount of shares redeemed and
will be assessed on an amount equal to the lesser of the current market value or
the cost of the shares being redeemed. The size of this percentage will depend
upon how long the shares have been held, as set forth in the following table:

    CDSC WAIVERS.  A CDSC will not be imposed on: (i) any amount which
represents an increase in value of shares purchased within the six years (or, in
the case of shares held by certain employer-sponsored benefit plans, three
years) preceding the redemption; (ii) the current net asset value of shares
purchased more than six years (or, in the case of shares held by certain
employer-sponsored benefit plans, three years) prior to the redemption; and
(iii) the current net asset value of shares purchased through reinvestment of
dividends or distributions 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
401(k) plan or other employer-

sponsored plan qualified under Section 401(a) of the Internal Revenue Code which
offers investment companies managed by the Investment Manager or its subsidiary,
Dean Witter Services Company Inc., as self-directed investment alternatives and
for which DWT serves as Trustee or the 401(k) Support Services Group of DWR
serves as recordkeeper ("Eligible Plan"), provided that either:  (a) the plan
continues to be an Eligible Plan after the redemption; or  (b) the redemption is
in connection with the complete termination of the plan involving the
distribution of all plan assets to participants.
    
 
    With reference to (1) above, for the purpose of determining disability, the
Distributor utilizes the definition of disability contained in Section 72(m)(7)
of the Internal Revenue Code, which relates to the inability to engage in
gainful employment. With reference to (2) above, the term "distribution" does
not encompass a direct transfer of IRA, 403(b) Custodial Account or retirement
plan assets to a successor custodian or trustee. All waivers will be granted
only following receipt by the Distributor of confirmation of the shareholder's
entitlement.
 
   
    CONVERSION TO CLASS A SHARES.  All shares of the Fund held prior to July 28,
1997 (other than shares which were purchased prior to November 8, 1989 (and,
with respect to such shares, including such proportion of shares acquired
through reinvestment of dividends and capital gains distributions as the total
number of shares acquired prior to such date bears to the total number of Fund
shares purchased and owned by a shareholder (collectively, the "Old Shares"))
and shares held by certain employee benefit plans established by DWR and its
affiliate, SPS Transaction Services, Inc.) have been designated Class B shares.
Shares held before May 1, 1997 that have been designated Class B shares will
convert to Class A shares in May, 2007. In all other instances Class B shares
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 401(k) plan or other
employer-sponsored plan qualified under Section 401(a) of the Internal Revenue
Code and for which DWT serves as Trustee or the 401(k) Support Services Group of
DWR serves as recordkeeper, the plan is treated as a single investor and all
Class B shares will convert to Class A shares on the conversion date of the
first shares of a 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
 
                                       26
<PAGE>
on the next scheduled conversion date after such certificates are received.
 
    Effectiveness of the conversion feature is subject to the continuing
availability of a ruling of the Internal Revenue Service or an opinion of
counsel that (i) the conversion of shares does not constitute a taxable event
under the Internal Revenue Code, (ii) Class A shares received on conversion will
have a basis equal to the shareholder's basis in the converted Class B shares
immediately prior to the conversion, and (iii) Class A shares received on
conversion will have a holding period that includes the holding period of the
converted Class B shares. The conversion feature may be suspended if the ruling
or opinion is no longer available. In such event, Class B shares would continue
to be subject to Class B 12b-1 fees.

   
    
 
LEVEL LOAD ALTERNATIVE--CLASS C SHARES
 
    Class C shares are sold at net asset value next determined without an
initial sales charge but are subject to a CDSC of 1.0% on most redemptions made
within one year after purchase (calculated from the last day of the month in
which the shares were purchased). The CDSC will be assessed on an amount equal
to the lesser of the current market value or the cost of the shares being
redeemed. The CDSC will not be imposed in the circumstances set forth above in
the section "Contingent Deferred Sales Charge Alternative--Class B Shares--CDSC
Waivers," except that the references to six years in the first paragraph of that
section shall mean one year in the case of Class C shares. Class C shares are
subject to an annual 12b-1 fee of up to 1.0% of the average daily net assets of
the Class. Unlike Class B shares, Class C shares have no conversion feature and,
accordingly, an investor that purchases Class C shares will be subject to 12b-1
fees applicable to Class C shares for an indefinite period subject to annual
approval by the Fund's Board of Trustees and regulatory limitations.
 
NO LOAD ALTERNATIVE--CLASS D SHARES
 
   
    Class D shares are offered without any sales charge on purchase or
redemption and without any 12b-1 fee. Class D shares are offered only to
investors meeting an initial investment minimum of $5 million and the following
categories of investors: (i) investors participating in the InterCapital mutual
fund asset allocation program pursuant to which such persons pay an asset based
fee; (ii) persons participating in a fee-based program approved by the
Distributor, pursuant to which such persons pay an asset based fee for services
in the nature 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. The Old Shares
and shares held by the employee benefit plans referred to in clause (iii) above
prior to July 28, 1997 have been designated Class D shares. Investors who
require a $5 million minimum initial investment to qualify to purchase Class D
shares may satisfy that requirement by investing that amount in a single
transaction in Class D shares of the Fund and other 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 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
 
                                       27
<PAGE>
the distribution of Class A, Class B and Class C shares of the Fund. In the case
of Class A and Class C shares, the Plan provides that the Fund will reimburse
the Distributor and others for the expenses of certain activities and services
incurred by them specifically on behalf of those shares. Reimbursements for
these expenses will be made in monthly payments by the Fund to the Distributor,
which will in no event exceed amounts equal to payments at the annual rates of
0.25% and 1.0% of the average daily net assets of Class A and Class C,
respectively. In the case of Class B shares, the Plan provides that the Fund
will pay the Distributor a fee, which is accrued daily and paid monthly, at the
annual rate of (i) 1.0% of the lesser of: (a) the average daily aggregate gross
sales of the Fund's Class B shares since the implementation of the Plan on
November 8, 1989 (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 implementation of the 12b-1 Plan upon which a
CDSC has been imposed or waived, or (b) the average daily net assets of Class B
attributable to shares issued, net of related shares redeemed, since
implementation of the 12b-1 Plan, plus (ii) 0.25% of the average daily net
assets of Class B attributable to shares issued, net of related shares redeemed,
prior to implementation of the 12b-1 Plan. The fee is treated by the Fund as an
expense in the year it is accrued. In the case of Class A shares, the entire
amount of the fee currently represents a service fee within the meaning of the
NASD guidelines. In the case of Class B and Class C shares, a portion of the fee
payable pursuant to the Plan, equal to 0.25% of the average daily net assets of
each of these Classes, is currently characterized as a service fee. A service
fee is a payment made for personal service and/or the maintenance of shareholder
accounts.
 
    Additional amounts paid under the Plan in the case of Class B and Class C
shares are paid to the Distributor for services provided and the expenses borne
by the Distributor and others in the distribution of the shares of those
Classes, including the payment of commissions for sales of the shares of those
Classes and incentive compensation to and expenses of DWR's account executives
and others who engage in or support distribution of shares or who service
shareholder accounts, including overhead and telephone expenses; printing and
distribution of prospectuses and reports used in connection with the offering of
the Fund's shares to other than current shareholders; and preparation, printing
and distribution of sales literature and advertising materials. In addition, the
Distributor may utilize fees paid pursuant to the Plan in the case of Class B
shares to compensate DWR and other Selected Broker-Dealers for their opportunity
costs in advancing such amounts, which compensation would be in the form of a
carrying charge on any unreimbursed expenses.
 
   
    For the fiscal year ended July 31, 1997, Class B shares of the Fund accrued
payments under the Plan amounting to $12,491,604, which amount is equal to 0.89%
of the average daily net assets of Class B for the fiscal year. These payments
were calculated pursuant to clauses (i)(a) and (ii) of the compensation formula
under the Plan. All shares held prior to July 28, 1997 (other than the Old
Shares and shares held by certain employee benefit plans established by DWR and
its affiliate, SPS Transaction Services, Inc.) have been designated Class B
shares. For the fiscal period July 28 through July 31, 1997, Class A and Class C
shares of the Fund accrued payments under the Plan amounting to $1 and $6,
respectively, which amounts on an annualized basis are equal to 0.25% and 1.0%
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
 
                                       28
<PAGE>
   
Distributor has advised the Fund that such excess amounts, including the
carrying charge described above, totalled $37,067,710 at July 31, 1997, which
was equal to 2.38% of the net assets of Class B on such date. Of this amount,
$13,444,602 represents excess distribution expenses of Dean Witter Managed
Assets Trust, the net assets of which were combined with those of the Fund on
December 22, 1995 pursuant to an Agreement and Plan of Reorganization. Because
there is no requirement under the Plan that the Distributor be reimbursed for
all distribution expenses or any requirement that the Plan be continued from
year to year, such excess amount does not constitute a liability of the Fund.
Although there is no legal obligation for the Fund to pay expenses incurred in
excess of payments made to the Distributor under the Plan and the proceeds of
CDSCs paid by investors upon redemption of shares, if for any reason the Plan is
terminated, the Trustees will consider at that time the manner in which to treat
such expenses. Any cumulative expenses incurred, but not yet recovered through
distribution fees or CDSCs, may or may not be recovered through future
distribution fees or CDSCs.
    
 
   
    In the case of Class A and Class C shares, expenses incurred pursuant to the
Plan in any calendar year in excess of 0.25% or 1.0% of the average daily net
assets of Class A or Class C, respectively, will not be reimbursed by the Fund
through payments in any subsequent year, except that expenses representing a
gross sales commission credited to account executives at the time of sale may be
reimbursed in the subsequent calendar year. The Distributor has advised the Fund
that there were no such expenses which may be reimbursed in the subsequent year
in the case of Class A and Class C on such date. No interest or other financing
charges will be incurred on any Class A or Class C distribution expenses
incurred by the Distributor under the Plan or on any unreimbursed expenses due
to the Distributor pursuant to the Plan.
    
 
DETERMINATION OF NET ASSET VALUE
 
    The net asset value per share is determined once daily at 4:00 p.m., New
York time (or, on days when the New York Stock Exchange closes prior to 4:00
p.m., at such earlier time), on each day that the New York Stock Exchange is
open by taking the net assets of the Fund, dividing by the number of shares
outstanding and adjusting to the nearest cent. The assets belonging to the Class
A, Class B, Class C and Class D shares will be invested together in a single
portfolio. The net asset value of each Class, however, will be determined
separately by subtracting each Class's accrued expenses and liabilities. The net
asset value per share will not be determined on Good Friday and on such other
federal and non-federal holidays as are observed by the New York Stock Exchange.
 
   
    In the calculation of the Fund's net asset value: (1) an equity portfolio
security listed or traded on the New York or American Stock Exchange is valued
at its latest sale price on that exchange prior to the time assets are valued;
if there were no sales that day, the security is valued at the latest bid price
(in cases where a security is traded on more than one exchange, the security is
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 bid price (in cases where a security is traded on more than one exchange,
the security is valued on the exchange designated as the primary market pursuant
to procedures adopted by the Trustees). When market quotations are not readily
available, including circumstances under which it is determined by 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 Fund's 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).
    
 
    Short-term debt securities with remaining maturities of sixty days or less
at the time of purchase are
 
                                       29
<PAGE>
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 the pricing
service believes is the fair valuation of such portfolio securities.
 
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 Redemtption").
 
   
    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, eligible Individual Retirement Accounts and
Custodial Accounts under Section 403(b)(7) of the Internal Revenue Code.
Adoption of such plans should be on advice of legal counsel or tax adviser.
 
                                       30

    For further information regarding plan administration, custodial fees and
other details, investors should contact their DWR or other Selected Broker-
Dealer account executive or the 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., Dean Witter High Income Securities and Dean Witter National Municipal
Trust, which are Dean Witter Funds offered with a CDSC ("CDSC Funds"). Exchanges
may be made after the shares of the Fund acquired by purchase (not by exchange
or dividend reinvestment) have been held for thirty days. There is no waiting
period for exchanges of shares acquired by exchange or dividend reinvestment.
 
    An exchange to another Dean Witter Multi-Class Fund, any FSC Fund, any CDSC
Fund or any Exchange Fund that is not a money market fund is on the basis of the
next calculated net asset value per share of each fund after the exchange order
is received. When exchanging into a money market fund from the Fund, shares of
the Fund are redeemed out of the Fund at their next calculated net asset value
and the proceeds of the redemption are used to purchase shares of the money
market fund at their net asset value determined the following business day.
Subsequent exchanges between any of the money market funds and any of the Dean
Witter Multi-Class Funds, FSC Funds or CDSC Funds or any Exchange Fund that is
not a money market fund can be effected on the same basis.
 
   
    No CDSC is imposed at the time of any exchange of shares, although any
applicable CDSC will be imposed upon ultimate redemption. During the period of
time the shareholder remains in an Exchange Fund (calculated from the last day
of the month in which the Exchange Fund shares were acquired), the holding
period (for the purpose of determining the rate of the CDSC) is frozen. If those
shares are subsequently re-exchanged for shares of a Dean Witter Multi-Class
Fund or shares of a CDSC Fund, the holding period previously frozen when the
first exchange was made resumes on the last day of the month in which shares of
a Dean Witter Multi-Class Fund or shares of a CDSC 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 a CDSC
Fund (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, if any, incurred on or after that
date which are attributable to those shares. (Exchange Fund 12b-1 distribution
fees are described in the prospectus for those funds.) Class B shares of the
Fund acquired in exchange for Class B shares of another Dean Witter Multi-Class
Fund or shares of a CDSC 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.
    
 
    ADDITIONAL INFORMATION REGARDING EXCHANGES. Purchases and exchanges should
be made for investment purposes only. A pattern of frequent
 
                                       31
<PAGE>
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 fraudulent instructions.
 
    Telephone exchange instructions will be accepted if received by the Transfer
Agent between 9:00 a.m. and 4:00 p.m., New York time, on any day the New York
Stock Exchange is open. Any shareholder wishing to make an exchange who has
previously filed an Exchange Privilege Authorization Form and who is unable to
reach the Fund by telephone should contact his or her DWR or other Selected
Broker-Dealer account executive, if
 
                                       32
<PAGE>
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 documentation 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, e.g., when normal trading is not taking place on the New
York Stock Exchange. 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 investment 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 their net asset value next determined after a reinstatement
request, together with the proceeds, is received by the Transfer Agent and
receive a pro rata credit for any CDSC paid in connection with such redemption
or repurchase.
 
    INVOLUNTARY REDEMPTION.  The Fund reserves the right, on 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
 
                                       33
<PAGE>
Internal Revenue Code) whose shares have a value of less than $100, or such
lesser amount as may be fixed by the Board of Trustees or, in the case of an
account opened through EasyInvest-SM-, if after twelve months the shareholder
has invested less than $1,000 in the account. However, before the Fund redeems
such shares and sends the proceeds to the shareholder it will notify the
shareholder that the value of the shares is less than the applicable amount and
allow the shareholder sixty days to make an additional investment in an amount
which will increase the value of the 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 quarterly income dividends and to
distribute net short-term and net long-term capital gains, if any, at least once
each year. The Fund may, however, determine either to distribute or to retain
all or part of any 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 capital gains to shareholders and otherwise continue
to qualify as a regulated investment company under Subchapter M of the Internal
Revenue Code, it is not expected that the Fund will be required to pay any
federal income tax. Shareholders who are required to pay taxes on their income
will normally have to pay federal income taxes, and any state income taxes, on
the dividends and distributions they receive from the Fund. Such dividends and
distributions, to the extent that they are derived from net investment income or
net 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,
for tax purposes, to have been received by the shareholder in the prior year.
 
    Gains or losses on the Fund's transactions in listed non-equity options,
futures and options on futures generally are treated as 60% long-term and 40%
short-term capital gains or losses. 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 gains being available for annual
distribution.
 
    One of the requirements for the Fund to remain qualified as a regulated
investment company is that less than 30% of the Fund's gross income be derived
from gains from the sale or other disposition of securities held for less than
three months. Accordingly, the Fund may be restricted in the writing of options
on securities held for less than three months, in the writing of options which
expire in less than three
 
                                       34
<PAGE>
months, and in effecting closing transactions with respect to call or put
options which have been written or purchased less than three months prior to
such transactions. The Fund may also be restricted in its ability to engage in
transactions involving futures contracts.
 
    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 corporate dividends received deduction.
 
    The Fund may at times make payments from sources other than income or net
capital gains.
Payments from such sources would, in effect, represent a return of a portion of
each shareholder's investment. All, or a portion, of such payments would not be
taxable to shareholders.
 
    After the end of the calendar year, shareholders will be sent full
information on their dividends and capital gains distributions for tax purposes.
To avoid being subject to a 31% federal backup withholding tax on taxable
dividends, capital gains distributions and the proceeds of redemptions and
repurchases, shareholders' taxpayer identification numbers must be furnished and
certified as to their accuracy.
 
    Shareholders should consult their tax advisers as to the applicability of
the foregoing to their current situation.
 
PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
 
    From time to time the Fund may quote its "total return" in advertisements
and sales literature. These figures are computed separately for Class A, Class
B, Class C and Class D shares. The total return of the Fund is based on
historical earnings and is not intended to indicate future performance. 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, or over the life of the Fund, if less than any of the foregoing. Average
annual total return reflects all income earned by the Fund, any appreciation or
depreciation of the Fund's assets, all expenses incurred by the applicable Class
and all sales charges which would be incurred by shareholders, for the stated
periods. It also assumes reinvestment of all dividends and distributions paid by
the Fund.
 
    In addition to the foregoing, the Fund may advertise its total return for
each Class over different periods of time by means of aggregate, average,
year-by-year or other types of total return figures. Such calculations may or
may not reflect the deduction of any sales charge which, if reflected, would
reduce the performance quoted. The Fund may also advertise the growth of
hypothetical investments of $10,000, $50,000 and $100,000 in each Class of
shares of the Fund. The Fund from time to time may also advertise its
performance relative to certain performance rankings and indexes compiled by
independent organizations (e.g., mutual fund performance rankings of Lipper
Analytical Services, Inc.; S&P 500 stock index; Dow Jones and Company, Inc.
Industrial Average).
 
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
 
                                       35
<PAGE>
proposal is submitted separately to Class A shareholders. Also, as discussed
herein, Class A, Class B and Class C bear the expenses related to the
distribution of their respective shares.
 
    The Fund is not required to hold Annual Meetings of Shareholders and in
ordinary circumstances the Fund does not intend to hold such meetings. The
Trustees may call Special Meetings of Shareholders for action by shareholder
vote as may be required by the Act or the Declaration of Trust. Under certain
circumstances, the Trustees may be removed by action of the Trustees or by the
Shareholders.
 
    Under Massachusetts law, shareholders of a business trust may, under certain
limited circumstances, be held personally liable as partners for obligations of
the Fund. However, the Declaration of Trust contains an express disclaimer of
shareholder liability for acts or obligations of the Fund, requires that Fund
obligations include such disclaimer, and provides for indemnification and
reimbursement of expenses out of the Fund's property for any shareholder held
personally liable for the obligations of the Fund. Thus, the risk of a
shareholder incurring financial loss on account of shareholder liability is
limited to circumstances in which the Fund itself would be unable to meet its
obligations. Given the above limitations on shareholder personal liability, and
the nature of the Fund's assets and operations, the possibility of the Fund
being unable to meet its obligations is remote and thus, 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 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 objective by investing all of its investable assets in a
non-diversified, open-end management investment company having the same
investment objective and policies and substantially the same investment
restrictions as those applicable to the Fund.
 
    SHAREHOLDER INQUIRIES.  All inquiries regarding the Fund should be directed
to the Fund at the telephone numbers or address set forth on the front cover of
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
August 5, 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 to Dean Witter InterCapital Inc.
thereafter.) The daily management of the Fund and research relating to the
Fund's portfolio are 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."
 
   
    InterCapital is also the investment manager or investment adviser of the

The foregoing investment companies, together with the Fund, are 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 investment
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 Growth Fund, TCW/DW Income and Growth Fund, TCW/DW Small Cap Growth
Fund, TCW/DW Balanced Fund, TCW/DW Total Return Trust, TCW/DW Mid-Cap Equity
Trust, TCW/DW Global Telecom Trust, TCW/DW Strategic Income Trust, TCW/DW
Emerging Markets 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) administrator of The BlackRock Strategic Term Trust Inc., a closed-end
investment company; and (ii) sub-administrator of MassMutual Participation
Investors and Templeton Global Governments Income Trust, closed-end investment
companies.
 
    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 objective. 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 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 such 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 Fund's shareholders; all expenses of shareholders'
and Trustees' meetings and of preparing, printing and mailing of proxy
statements and reports to shareholders; fees and travel expenses of Trustees or
members of any advisory board or committee who are not employees of the
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;
    
 
                                       4
<PAGE>
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 by applying the
following annual rates to the Fund's daily net assets: 0.60% of the portion of
the daily net assets not exceeding $500 million; 0.55% of the next $500 million;
0.50% of the next $500 million; and 0.475% of the portion of the daily net
assets exceeding $1.5 billion. The management fee is allocated among the Classes
pro rata based on the net assets of the Fund attributable to each Class. For the
fiscal years ended July 31, 1995, 1996 and 1997, the Fund accrued to the
Investment Manager total compensation of $4,679,443, $6,414,184 and $7,751,652,
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, as such agreement had been
amended by the Trustees at their meetings held on April 28, 1993 and April 17,
1996, to lower the management fees charged on the Fund's daily net assets in
excess of $1 billion and $1.5 billion. 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 Trustees of the Fund, by the holders of a
majority, as defined in the Act, of the outstanding shares of the Fund, or by
the 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.
 
    The Fund has acknowledged that the name "Dean Witter" is a property right of
DWR. The Fund has agreed that DWR or its parent company may use, or at any time
permit others to use, the name "Dean Witter." The Fund has also agreed that in
the event the Agreement is terminated, or if the affiliation between
InterCapital and its parent company is terminated, the Fund will eliminate the
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 currently 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 127 portfolios. As of August 31, 1997, the Dean Witter Funds had
total net assets of approximately $90.6 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, 1996,
the three Committees held a combined total of sixteen 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
 
                                       8
<PAGE>
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.
 
    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, since July
1, 1996, 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
 
                                       9
<PAGE>
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 $1,000 plus a per
meeting fee of $50 for meetings of the Board of Trustees or committees of the
Board of Trustees attended by the Trustee (the Fund pays the Chairman of the
Audit Committee an annual fee of $750 and pays the Chairman of the Committee of
the Independent Trustees an additional annual fee of $1,200). If a Board meeting
and a Committee meeting, or more than one Committee meeting, take place on a
single day, the Trustees are paid a single meeting fee by the Fund. The Fund
also reimburses such Trustees for travel and other out-of-pocket expenses
incurred by them in connection with attending such meetings. Trustees and
officers of the Fund who are or have been employed by the Investment Manager or
an affiliated company receive no compensation or expense reimbursement from the
Fund.
    
 
   
    The following table illustrates the compensation paid to the Fund's
Independent Trustees by the Fund for the fiscal year ended July 31, 1997.

    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
 
                                       10
<PAGE>
referred to as an "Adopting Fund" and each such Trustee referred to as an
"Eligible Trustee") is entitled to retirement payments upon reaching the
eligible retirement age (normally, after attaining age 72). Annual payments are
based upon length of service. Currently, upon retirement, each Eligible Trustee
is entitled to receive from the Adopting Fund, commencing as of his or her
retirement date and continuing for the remainder of his or her life, an annual
retirement benefit (the "Regular Benefit") equal to 25.0% of his or her Eligible
Compensation plus 0.4166666% of such Eligible Compensation for each full month
of service as an Independent Director or Trustee of any Adopting Fund in excess
of five years up to a maximum of 50.0% after ten years of service. The foregoing
percentages may be changed by the Board.(1) "Eligible Compensation" is one-fifth
of the total compensation earned by such Eligible Trustee for service to the
Adopting Fund in the five year period prior to the date of the Eligible
Trustee's retirement. Benefits under the retirement program are not secured or
funded by the Adopting Funds.
 
   
    The following table illustrates the retirement benefits accrued to the
Fund's Independent Trustees by the Fund for the fiscal year ended July 31, 1997
and by the 57 Dean Witter Funds (including the Fund) as of December 31, 1996,

commence upon their retirement, from the Fund as of July 31, 1997 and from the

(1) An Eligible Trustee may elect alternate payments of his or her retirement
    benefits based upon the combined life expectancy of such Eligible Trustee
    and his or her spouse on the date of such Eligible Trustee's retirement. The
    amount estimated to be payable under this method, through the remainder of
    the later of the lives of such Eligible Trustee and spouse, will be the
    actuarial equivalent of the Regular Benefit. In addition, the Eligible
    Trustee may elect that the surviving spouse's periodic payment of benefits
    will be equal to either 50% or 100% of the previous periodic amount, an
    election that, respectively, increases or decreases the previous periodic
    amount so that the resulting payments will be the actuarial equivalent of
    the Regular Benefit.
 
(2) Based on current levels of compensation. Amount of annual benefits also
    varies depending on the Trustee's elections described in Footnote (1) above.
 
(3) These numbers reflect the effect of the combination of the net assets of
    Dean Witter Managed Assets Trust with those of the Fund on December 22, 1995
    pursuant to an Agreement and Plan of Reorganization.
 
    As of the date of this Statement of Additional Information, the aggregate
number of shares of beneficial interest of the Fund owned by the Fund's officers
and Trustees as a group was less than 1 percent of the Fund's shares of
beneficial interest outstanding.
 
INVESTMENT PRACTICES AND POLICIES
- --------------------------------------------------------------------------------
 
    U.S. GOVERNMENT SECURITIES.  As stated in the Prospectus, the Fund may
invest in short-term to intermediate (one to five year maturities) and
intermediate to long term (greater than five year maturities) fixed-income
securities which are issued or guaranteed, as to principal and interest, by the
United States or its agencies and instrumentalities.
 
                                       11
<PAGE>
    Such U.S. Government securities include:
 
        (1) U.S. Treasury bills (maturities of one year or less), U.S. Treasury
    notes (maturities of one to ten years) and U.S. Treasury bonds (generally
    maturities of greater than ten years), all of which are direct obligations
    of the U.S. Government and, as such, are backed by the "full faith and
    credit" of the United States.
 
        (2) Securities issued by agencies and instrumentalities of the U.S.
    Government which are backed by the full faith and credit of the United
    States. Among the agencies and instrumentalities issuing such obligations
    are the Federal Housing Administration, the Government National Mortgage
    Association ("GNMA"), the Department of Housing and Urban Development, the
    Export-Import Bank, the Farmers Home Administration, the General Services
    Administration, the Maritime Administration and the Small Business
    Administration. The maturities of such obligations range from three months
    to thirty 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.
 
    ZERO COUPON SECURITIES.  A portion of the U.S. Government 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 if prevailing interest rates rise. For this
reason, zero coupon securities are subject to substantially greater price
fluctuations during periods of changing prevailing interest rates than are
comparable securities which pay interest currently.
 
    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 billion or more, and instruments secured by
    such obligations, not including obligations of foreign branches of domestic
    banks except to the extent below;
 
        EURODOLLAR CERTIFICATES OF DEPOSIT.  Eurodollar certificates of deposit
    issued by foreign branches of domestic banks having total assets of $1
    billion or more;
 
        OBLIGATIONS OF SAVINGS INSTITUTIONS.  Certificates of deposit of savings
    banks and savings and loan associations, having total assets of $1 billion
    or more;
 
                                       12
<PAGE>
        FULLY INSURED CERTIFICATES OF DEPOSIT.  Certificates of deposit of banks
    and savings institutions, having total assets of less than $1 billion, if
    the principal amount of the obligation is insured by the 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 Corporation ("S&P") or the highest grade by Moody's
    Investors Service, Inc. ("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.
 
    LENDING OF PORTFOLIO SECURITIES.  Consistent with applicable regulatory
requirements, the Fund may lend its portfolio securities to brokers, dealers and
other financial institutions, provided that such loans are callable at any time
by the Fund (subject to notice provisions described below), and are at all times
secured by cash or cash equivalents, which are maintained in a segregated
account pursuant to applicable regulations and that are equal to at least the
market value, determined daily, of the loaned securities. The advantage of such
loans is that the Fund continues to receive the income on the loaned securities
while at the same time earning interest on the cash amounts deposited as
collateral, which will be invested in short-term obligations. The Fund will not
lend its portfolio securities if such loans are not permitted by the laws or
regulations of any state in which its shares are qualified for sale and will not
lend more than 25% of the value of its total assets. A loan may be terminated by
the borrower on one business 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 did not
lend any of its portfolio securities during the fiscal year ended July 31, 1997.
    
 
    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 added to the
account to maintain full collateralization. The Fund will accrue interest from
the institution until the time when the repurchase is to occur. Although such
date is deemed by the Fund to be the maturity date of a repurchase agreement,
the maturities of securities subject to repurchase agreements are not subject to
any limits and may exceed one year.
 
                                       13

    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. In addition, as described above, the
value of the collateral underlying the repurchase agreement will be at least
equal to the repurchase price, including any accrued interest earned on the
repurchase agreement. In the event of a default or bankruptcy by a selling
financial institution, the Fund will seek to liquidate such collateral. However,
the exercising of the Fund's right to liquidate such collateral could involve
certain costs or delays and, to the extent that proceeds from the sale upon a
default of the obligation to repurchase were less than the repurchase price, the
Fund could suffer a loss. The Fund has not to date and 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 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 otherwise obtaining the cash. Opportunities
to achieve this advantage may not always be available. The Fund will establish a
segregated account with its custodian bank in which it will maintain cash, U.S.
Government securities or other liquid portfolio securities equal in value to its
obligations in respect of reverse repurchase agreements. Reverse repurchase
agreements are considered borrowings by the Fund and for purposes other than
meeting redemptions may not exceed 5% of the Fund's total assets.
 
    WARRANTS.  The Fund may acquire warrants attached to other securities and,
in addition may invest up to 5% of the value of its total assets in warrants,
including up to 2% of such assets in warrants not listed on either the New York
or American Stock Exchange. Warrants are, in effect, an option to purchase
equity securities at a specific price, generally valid for a specific period of
time, and have no voting rights, pay no dividends and have no rights with
respect to the corporation issuing them.
 
    WHEN-ISSUED AND DELAYED DELIVERY SECURITIES.  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, i.e., delivery
and payment can take place a month or more after the date of the transactions.
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 Board
of 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
 
                                       14
<PAGE>
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.
 
OPTIONS AND FUTURES TRANSACTIONS
 
    The Fund may write covered call options against securities held in its
portfolio and covered put options on eligible portfolio securities and stock
indexes and purchase options of the same series to effect closing 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 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.
 
                                       15
<PAGE>
    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 a loss and incur
transaction costs.
 
    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. The Fund will engage in OTC option
transactions only with primary U.S. Government securities dealers recognized by
the Federal Reserve Bank of New York.
 
    COVERED CALL WRITING.  The Fund is permitted to write covered call options
on portfolio securities and on stock index options, without limit, in order to
aid in achieving its investment objective. Generally, a call option is "covered"
if the Fund owns, or has the right to acquire, without additional cash
consideration (or for additional cash consideration held for the Fund by its
Custodian in a segregated account) the underlying security subject to the option
except that in the case of call options on U.S. Treasury Bills, the Fund might
own U.S. Treasury Bills of a different series from those underlying the call
option, but with a principal amount and value corresponding to the exercise
price and a maturity date no later than that of the securities deliverable under
the call option. A call option is also covered if the Fund holds a call on the
same security as the underlying security of the written option, where the
exercise price of the call used for coverage is equal to or less than the
exercise price of the call written or greater than the exercise price of the
call written if the mark-to-market difference is maintained by the Fund in cash,
U.S. Government securities or other liquid portfolio securities which the Fund
holds in a segregated account maintained with its Custodian.
 
    The Fund will receive from the purchaser, in return for a call it has
written, a "premium"; i.e., the price of the option. Receipt of these premiums
may better enable the Fund to achieve a greater total return than would be
realized from holding the underlying securities alone. Moreover, the premium
received will offset a portion of the potential loss incurred by the Fund if the
securities underlying the option are ultimately sold by the Fund at a loss. The
value of the premium received will fluctuate with varying economic market
conditions.
 
    As regards listed options and certain OTC options, during the option period,
the Fund may be required, at any time, to deliver the underlying security
against payment of the exercise price on any calls it has written (exercise of
certain listed and OTC options may be limited to specific expiration dates).
This obligation is terminated upon the expiration of the option period or at
such earlier time when the writer effects a closing purchase transaction. A
closing purchase transaction is accomplished by purchasing an option of the same
series as the option previously written.
 
    Closing purchase transactions are ordinarily effected to realize a profit on
an outstanding call option to prevent an underlying security from being called,
to permit the sale of an underlying security or to
 
                                       16
<PAGE>
enable the Fund to write another call option on the underlying security with
either a different exercise price or expiration date or both. Also, effecting a
closing purchase transaction will permit the cash or proceeds from the
concurrent sale of any securities subject to the option to be used for other
investments by the Fund. The Fund may realize a net gain or loss from a closing
purchase transaction depending upon whether the amount of the premium received
on the call option is more or less than the cost of effecting the closing
purchase transaction. Any loss incurred in a closing purchase transaction may be
wholly or partially offset by unrealized appreciation in the market value of the
underlying security. Conversely, a gain resulting from a closing purchase
transaction could be offset in whole or in part or exceeded by a decline in the
market value of the underlying security.
 
    If a call option expires unexercised, the Fund realizes a gain in the amount
of the premium on the option less the commission paid. Such a gain, however, may
be offset by depreciation in the market value of the underlying security during
the option period. If a call option is exercised, the Fund realizes a gain or
loss from the sale of the underlying security equal to the difference between
the purchase price of the underlying security and the proceeds of the sale of
the security plus the premium received for on the option less the commission
paid.
 
    Options written by a Fund normally have expiration dates of from up to nine
months (equity securities) to eighteen months (fixed-income securities) from the
date written. The exercise price of a call option may be below, equal to or
above the current market value of the underlying security at the time the option
is written. See "Risks of Options and Futures Transactions," below.
 
    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 underlying such option. Such a sale would result in a net gain
or loss depending on whether the amount received on the sale is more or less
than the premium and other transaction costs paid on the put option which is
sold. Any such gain or loss could be offset in whole or in part by a change in
the market value of the underlying security. If a put option purchased by the
Fund expired without being sold or exercised, the premium would be lost.
 
    COVERED PUT WRITING.  As a writer of a covered put option, the Fund incurs
an obligation to buy the security underlying the option from the purchaser of
the put, at the option's exercise price at any time during the option period, at
the purchaser's election (certain listed and OTC put options written by the Fund
will be exercisable by the purchaser only on a specific date). A put is
"covered" if 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 written put position
could be covered by the Fund by its purchase of a put option on the same
security as the underlying security of the written option, where the exercise
price of the purchased option is equal to or more than the exercise price of the
put written or less than the exercise price of the put written if the
mark-to-market difference is maintained by the Fund in cash, U.S. Government
securities or other liquid portfolio securities which the Fund holds in a
segregated account maintained at its Custodian. In 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. The operation
of and limitations on covered put options in other respects are substantially
identical to those of call options.
 
    The Fund will write put options for two purposes: (1) to receive the income
derived from the premiums paid by purchasers; and (2) when the Investment
Manager wishes to purchase the security underlying the option at a price lower
than its current market price, in which case it will write the covered put at an
exercise price reflecting the lower purchase price sought. The potential gain on
a covered put option is limited to the premium received on the option (less the
commissions paid on the transaction) while the potential loss equals the
difference between the exercise price of the option and the current market price
of the underlying securities when the put is exercised, offset by the premium
received (less the commissions paid on the transaction).
 
                                       17
<PAGE>
    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 in order to close out a covered call position (see
"Covered Call Writing" above) and, as to 2% of its total assets, purchase call
options on securities it intends to purchase. If, in the latter case, the price
of the security 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. A call purchased to close out a
position is likely to be on the same securities and have the same terms as the
written option. The option would generally be acquired from the dealer or
financial institution which purchased the call written by the Fund.
 
    The Fund may purchase put options on securities which it holds (or has the
right to acquire) in its portfolio only to protect itself against a decline in
the value of the security. If the value of the underlying security were to fall
below the exercise price of the put purchased in an amount greater than the
premium paid for the option, the Fund would incur no additional loss. 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 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 when it was
purchased. Any such gain or loss could be offset in whole or in part by a change
in the market value of the underlying security. If a put option purchased by the
Fund expired without being sold or exercised, the premium would be lost.
 
    RISKS OF OPTIONS TRANSACTIONS.  The successful use of options depends on the
ability of the Investment Manager to forecast correctly interest rates and
market movements. If the market value of the portfolio securities upon which
call options have been written increases, the Fund may receive a lower total
return from the portion of its portfolio upon which calls have been written than
it would have had such calls not been written. In writing puts, the Fund assumes
the risk of loss should the market value of the underlying securities decline
below the exercise price of the option (any loss being decreased by the receipt
of the premium on the option written). During the option period, the covered
call writer has, in return for the premium on the option, given up the
opportunity for capital appreciation above the exercise price should the market
price of the underlying security increase, but has retained the risk of loss
should the price of the underlying security decline. The secured put writer also
retains the risk of loss should the market value of the underlying security
decline below the exercise price of the option less the premium received on the
sale of the option. In both cases, the writer has no control over the time when
it may be required to fulfill its obligation as a writer of the option. Once an
option writer has received an exercise notice, it cannot effect a closing
purchase transaction in order to terminate its obligation under the option and
must deliver or receive the underlying securities at the exercise price.
 
    Prior to exercise or expiration, an option position can only be terminated
by entering into a closing purchase or sale transaction. If a covered call
option writer is unable to effect a closing purchase transaction or to purchase
an offsetting 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 covered put option writer who is unable to
effect a closing purchase transaction or to purchase an offsetting over-the-
counter option would continue to bear the risk of decline in the market price of
the underlying security until the option expires or is exercised. In addition, a
covered put writer would be unable to utilize the amount held in cash or U.S.
Government or other liquid portfolio securities as cover for the put option for
other investment purposes until the exercise or expiration of the option.
 
    The Fund's ability to close out its position as a writer of an option is
dependent upon the existence of a liquid secondary market on option exchanges.
There is no assurance that such a market will exist, particularly in the case of
OTC options, as such options will generally only be closed out by entering into
a closing purchase 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
 
                                       18
<PAGE>
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
exercisable 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).
 
    STOCK INDEX OPTIONS.  Options on stock indexes are similar to options on
stock except that, rather than the right to take or make delivery of stock at a
specified price, an option on a stock index gives the holder the right to
receive, upon exercise of the option, an amount of cash if the closing level of
the stock index upon which the option is based is greater than, in the case of a
call, or less than, in the case of a put, the exercise price of the option. This
amount of cash is equal to such difference between the closing price of the
index and the exercise price of the option expressed in dollars times a
specified multiple (the "multiplier"). The multiplier for an index option
performs a function similar to the unit of trading for a stock option. It
determines the total dollar value per contract of each point in the difference
between the exercise price of an option and the current level of the underlying
index. A multiplier of 100 means that a one-point difference will yield $100.
Options on different indexes may have different multipliers. The writer of the
option is obligated, in return for the premium received, to make delivery of
this amount. Unlike stock options, all settlements are in cash and a gain or
loss depends on price movements in the stock market generally (or in a
particular segment of the market) rather than the price movements in individual
stocks. Currently, options are traded on, among other indexes, the Standard &
Poor's 100 Index and the Standard & Poor's 500 Index on the Chicago Board
Options Exchange, the Major Market Index and the Computer Technology Index, Oil
Index and Institutional Index on the American Stock Exchange and the NYSE Index
and NYSE Beta Index on the New York Stock Exchange, The Financial
 
                                       19
<PAGE>
News Composite Index on the Pacific Stock Exchange and the Value Line Index,
National O-T-C Index and Utilities Index on the Philadelphia Stock Exchange,
each of which and any similar index on which options are traded in the future
which include stocks that are not limited to any particular industry or segment
of the market is referred to as a "broadly based stock market index." The Fund
will invest only in broadly based indexes. Options on broad-based stock indexes
provide the Fund with a means of protecting the Fund against the risk of
market-wide price movements. If the Investment Manager anticipates a market
decline, the Fund could purchase a stock index put option. If the expected
market decline materialized, the resulting decrease in the value of the Fund's
portfolio would be offset to the extent of the increase in the value of the put
option. If the Investment Manager anticipates a market rise, the Fund may
purchase a stock index call option to enable the Fund to participate in such
rise until completion of anticipated common stock purchases by the Fund.
Purchases and sales of stock index options also enable the Investment Manager to
more speedily achieve changes in the Fund's equity positions.
 
    The Fund will be able to write put options on stock indexes only if such
positions are covered by cash, U.S. Government securities or other liquid
portfolio securities equal to the aggregate exercise price of the puts, or by a
put option on the same stock index with a strike price no lower than the strike
price of the put option sold by the Fund, which cover is held for the Fund in a
segregated account maintained for it by the Fund's Custodian. All call options
on stock indexes written by the Fund will be covered either by a portfolio of
stocks substantially replicating the movement of the index underlying the call
option or by holding a separate call option on the same stock index with a
strike price no higher than the strike price of the call option sold by the
Fund.
 
    RISKS OF OPTIONS ON INDEXES.  Because exercises of stock index options are
settled in cash, the Fund, as a call writer, would not be able to provide in
advance for their potential settlement obligations by acquiring and holding the
underlying securities. A call writer can offset some of the risk of its writing
position by holding a diversified portfolio of stocks similar to those on which
the underlying index is based. However, most investors cannot, as a practical
matter, acquire and hold a portfolio containing exactly the same stocks as the
underlying index, and, as a result, bear a risk that the value of the securities
held will vary from the value of the index. Even if an index call writer could
assemble a stock portfolio that exactly reproduced the composition of the
underlying index, the writer still would not be fully covered from a risk
standpoint because of the "timing risk" inherent in writing index options. When
an index option is exercised, the amount of cash that the holder is entitled to
receive is determined by the difference between the exercise price and the
closing index level on the date when the option is exercised. As with other
kinds of options, the writer will not learn that it has been assigned until the
next business day, at the earliest. The time lag between exercise and notice of
assignment poses no risk for the writer of a covered call on a specific
underlying security, such as a common stock, because there the writer's
obligation is to deliver the underlying security, not to pay its value as of a
fixed time in the past. So long as the writer already owns the underlying
security, it can satisfy its settlement obligations by simply delivering it, and
the risk that its value may have declined since the exercise date is borne by
the exercising holder. In contrast, even if the writer of an index call holds
stocks that exactly match the composition of the underlying index, it will not
be able to satisfy its assignment obligations by delivering those stocks against
payment of the exercise price. Instead, it will be required to pay cash in an
amount based on the closing index value on the exercise date; and by the time it
learns that it has been assigned, the index may have declined with a
corresponding decrease in the value of its stock portfolio. This "timing risk"
is an inherent limitation on the ability of index call writers to cover their
risk exposure by holding stock positions.
 
    A holder of an index option who exercises it before the closing index value
for that day is available runs the risk that the level of the underlying index
may subsequently change. If such a change causes the exercised option to fall
out-of-the-money, the exercising holder will be required to pay the difference
between the closing index value and the exercise price of the option (times the
applicable multiplier) to the assigned writer.
 
                                       20
<PAGE>
    If dissemination of the current level of an underlying index is interrupted,
or if trading is interrupted in stocks accounting for a substantial portion of
the value of an index, the trading of options on that index will ordinarily be
halted. If the trading of options on an underlying index is halted, an exchange
may impose restrictions prohibiting the exercise of such options.
 
    FUTURES CONTRACTS.  As stated in the Prospectus, the Fund may purchase and
sell interest rate and stock index futures contracts ("futures contracts") that
are traded on U.S. commodity exchanges on such underlying securities as U.S.
Treasury bonds, notes, bills and GNMA Certificates ("interest rate futures") and
such indexes as the S&P 500 Index, the Moody's Investment-Grade Corporate Bond
Index and the New York Stock Exchange Composite Index ("index futures").
 
    As a futures contract purchaser, the Fund incurs an obligation to take
delivery of a specified amount of the obligation underlying the contract at a
specified time in the future for a specified price. As a seller of a futures
contract, the Fund incurs an obligation to deliver the specified amount of the
underlying obligation at a specified time in return for an agreed upon price.
 
    The Fund will purchase or sell interest rate futures contracts and bond
index futures contracts for the purpose of hedging its fixed-income portfolio
(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.
 
    The Fund will purchase or sell stock index futures contracts for the purpose
of hedging its equity portfolio (or anticipated portfolio) against changes in
their prices. If the Investment Manager anticipates that the prices of stock
held by the Fund may fall or wishes to decrease the Fund's asset allocation in
equity securities, the Fund may sell a stock index futures contract. Conversely,
if the Investment Manager wishes to increase the Fund's assets which are
invested in stocks or as a hedge against anticipated price rises in those stocks
which the Fund intends to purchase, the Fund may purchase stock index futures
contracts. This allows the Fund to purchase equities, in accordance with the
Investment Manager's asset allocations, in an orderly and efficacious manner. In
addition, interest rate and stock index futures contracts will be bought or sold
in order to close out a short or long position in a corresponding futures
contract.
 
    Although most interest rate futures contracts call for actual delivery or
acceptance of securities, the contracts usually are closed out before the
settlement date without the making or taking of delivery. Stock index futures
contracts provide for the delivery of an amount of cash equal to a specified
dollar amount times the difference between the stock index value at the open or
close of the last trading day of the contract and the futures contract price. A
futures contract sale is closed out by effecting a futures contract purchase for
the same aggregate amount of the specific type of equity security and the same
delivery date. If the sale price exceeds the offsetting purchase price, the
seller would be paid the difference and would realize a gain. If the offsetting
purchase price exceeds the sale price, the seller would pay the difference and
would realize a loss. Similarly, a futures contract purchase is closed out by
effecting a futures contract sale for the same aggregate amount of the specific
type of equity security and the same delivery date. If the offsetting sale price
exceeds the purchase price, the purchaser would realize a gain, whereas if the
purchase price exceeds the offsetting sale price, the purchaser would realize a
loss. There is no assurance that the Fund will be able to enter into a closing
transaction.
 
    INTEREST RATE FUTURES.  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
 
                                       21
<PAGE>
portfolio securities equal to approximately 2% of the contract amount. Initial
margin requirements are established by the Exchanges on which futures contracts
trade and may, from time to time, change. In addition, brokers may establish
margin deposit requirements in excess of those required by the Exchanges.
 
    Initial margin in futures transactions is different from margin in
securities transactions in that initial margin does not involve the borrowing of
funds by a broker's 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 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.
 
    INDEX FUTURES.  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 a gain.
 
    Currently, index futures contracts can be purchased or sold with respect to,
among others, the Standard & Poor's 500 Stock Price Index and the Standard &
Poor's 100 Stock Price Index on the Chicago Mercantile Exchange, the New York
Stock Exchange Composite Index on the New York Futures Exchange, the Major
Market Index on the American Stock Exchange, the Value Line Stock Index on the
Kansas City Board of Trade and the Moody's Investment-Grade Corporate Bond Index
on the Chicago Board of Trade.
 
    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
 
                                       22
<PAGE>
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.
 
    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 initial margin plus the amount paid for
premiums for unexpired options on futures contracts exceeds 5% of the value of
the Fund's total assets, after taking into account unrealized gains and
unrealized losses on such contracts it has entered into, provided, however, that
in the case of an option that is in-the-money (the exercise price of the call
(put) option is less (more) than the market price of the underlying security) at
the time of purchase, the in-the-money amount may be excluded in calculating the
5%. However, there is no overall limitation on the percentage of the Fund's
assets which may be subject to a hedge position. In addition, in accordance with
the regulations of the Commodity Futures Trading Commission ("CFTC") under which
the Fund is exempted from registration as a commodity pool operator, the Fund
may only enter into futures contracts and options on futures contracts
transactions for purposes of hedging a part or all of its portfolio. If the CFTC
changes its regulations so that the Fund would be permitted to write options on
futures contracts for purposes other than hedging the Fund's investments without
CFTC registration, the Fund may engage in such transactions for those purposes.
Except as described above, there are no other limitations on the use of futures
and options thereon by the Fund.
 
    RISKS OF TRANSACTIONS IN FUTURES CONTRACTS AND RELATED OPTIONS.  The
successful use of futures and related options depends on the ability of the
Investment Manager to accurately predict market and interest rate movements. As
stated in the prospectus, the Fund may sell a futures contract to protect
against the decline in the value of securities held by the Fund. However, it is
possible that the futures market may advance and the value of securities held in
the portfolio of the Fund may decline. If this occurred, the Fund would lose
money on the futures contract and also experience a decline in value of its
portfolio securities. However, while this could occur for a very brief period or
to a very small degree, over time the value of a diversified portfolio will tend
to move in the same direction as the futures contracts.
 
    If the Fund purchases a futures contract to hedge against the increase in
value of securities it intends to buy, and the value of such securities
decreases, then the Investment Manager 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 maintains a short position in a futures contract or has sold a
call option on a futures contract, it will cover this position by holding, in a
segregated account maintained at its Custodian, cash, U.S. Government securities
or other high grade debt obligations equal in value (when added to any initial
or variation margin on deposit) to the market value of the securities underlying
the futures contract or the exercise price of the option. Such a position may
also be covered by owning the securities underlying the futures contract (in the
case of a stock index futures contract a portfolio of securities substantially
replicating the relevant index), or by holding a call option permitting the Fund
to purchase the same contract at a price no higher than the price at which the
short position was established.
 
    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
 
                                       23
<PAGE>
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
contracts it holds at a time when it is disadvantageous to do so. The inability
to close out options and futures positions could also have an adverse impact on
the Fund's ability to effectively hedge its portfolio.
 
    In the event of the bankruptcy of a broker through which the Fund engages in
transactions in 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 is that the prices of securities
and indexes subject to futures contracts (and thereby the futures contract
prices) may correlate imperfectly with the behavior of the cash prices of the
Fund's portfolio securities. Another such risk is that prices of interest rate
futures contracts may not move in tandem with the changes in prevailing interest
rates against which the Fund seeks a hedge. A correlation may also be distorted
by the fact that the futures market is dominated by short-term traders seeking
to profit from the difference between a contract or security price objective and
their cost of borrowed funds. Such distortions are generally minor and would
diminish as the contract approached maturity.
 
    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 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 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.
 
    There is no assurance that a liquid secondary market will exist for futures
contracts and related options in which the Fund may invest. In the event a
liquid market does not exist, it may not be possible to close out a futures
position, and in the event of adverse price movements, the Fund would continue
to be required to make daily cash payments of variation margin. In addition,
limitations imposed by an exchange or board of trade on which futures contracts
are traded may compel or prevent the Fund from closing out a contract which may
result in reduced gain or increased loss to the Fund. The absence of a liquid
market in futures contracts might cause the Fund to make or take delivery of the
underlying securities at a time when it may be disadvantageous to do so.
 
                                       24
<PAGE>
    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.
 
    The Investment Manager has substantial experience in the use of the
investment techniques described above under the heading "Options and Futures
Transactions," which techniques require skills different from those needed to
select the portfolio securities underlying various options and futures
contracts.
 
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/ director of the Fund or of the Investment
    Manager owns more than 1/2 of 1% of the outstanding securities of such
    issuer, and such officers and trustees/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.    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. The
    staff of the Securities and Exchange Commission ("SEC") has taken the
    position that purchased OTC options and the assets used as "cover" for
    written OTC options are illiquid securities and the Fund will treat these
    assets as such.
 
         4.    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.
 
         5.    Purchase securities of other investment companies, except in
    connection with a merger, consolidation, reorganization or acquisition of
    assets.
 
         6.    Borrow money (except insofar as to the Fund may be deemed to have
    borrowed by entrance into a reverse repurchase agreement), except that the
    Fund may, but not to leverage the Fund's assets, 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).
 
                                       25
<PAGE>
         7.    Pledge its assets or assign or otherwise encumber them except to
    secure borrowings effected within the limitations set forth in restriction
    (6). 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.
 
         8.    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
    borrowing money in accordance with restrictions described above.
 
         9.    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 objective and policies; (b) by investment in
    repurchase agreements; or (c) by lending its portfolio securities.
 
        10.   Make short sales of securities.
 
        11.   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.
 
        12.   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.
 
        13.   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 objective by investing all or substantially all
of its assets in another investment company having substantially the same
investment objective 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. 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 July 31, 1995, 1996 and
1997, the Fund paid a total of $845,540, $1,417,865 and $1,189,162,
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
 
                                       26
<PAGE>
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.
 
   
    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 information or opinions pertaining to investment; wire
services; and appraisals or evaluations of portfolio securities. During the
fiscal year ended July 31, 1997, the Fund directed the payment of $1,114,797 in
brokerage commissions in connection with transactions in the aggregate amount of
$735,355,459 to brokers 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 such 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.
 
    Consistent with the policy described above, brokerage transactions in
securities listed on exchanges or admitted to unlisted trading privileges may be
effected through DWR and other affiliated brokers and dealers. In order for an
affiliated broker or dealer to effect any portfolio transactions for the Fund,
the commissions, fees or other remuneration received by the affiliated broker or
dealer must be reasonable and fair compared to the commissions, fees or other
remuneration paid to other brokers in connection with comparable transactions
involving similar securities being purchased or sold on an exchange during a
comparable period of time. This standard would allow 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 Board of Trustees of the Fund, including a majority of the
Trustees who are not "interested" persons of the Fund, as defined in the Act,
have adopted procedures which are reasonably designed to provide that any
commissions, fees or
 
                                       27
<PAGE>
   
other remuneration paid to an affiliated broker or dealer are consistent with
the foregoing standard. The Fund does not reduce the management fee it pays to
the Investment Manager by any amount of the brokerage commissions it may pay to
an affiliated broker or dealer. During the fiscal years ended July 31, 1995,
1996 and 1997, the Fund paid a total of $84,770, $105,265 and $37,367,
respectively, in brokerage commissions to DWR. The brokerage commissions paid to
DWR represented approximately 3.14% of the total brokerage commissions paid by
the Fund for the fiscal year ended July 31, 1997 and were paid on account of
transactions having an aggregate dollar value equal to approximately 6.68% of
the aggregate dollar value of all portfolio transactions of the Fund during the
period for which commissions were paid. During the period June 1 through July
31, 1997, the Fund paid a total of $1,005 in brokerage commissions to Morgan
Stanley & Co., Inc., which broker-dealer became an affiliate of the Investment
Manager on May 31, 1997 upon consummation of the merger of Dean Witter, Discover
& Co. with Morgan Stanley Group Inc. The brokerage commissions paid to Morgan
Stanley & Co., Inc. represented approximately 0.08% of the total brokerage
commissions paid by the Fund for this period and were paid on account of
transactions having an aggregate dollar value equal to approximately 0.10% of
the aggregate dollar value of all portfolio transactions of the Fund during the
period for which commissions were paid.
    
 
   
    During the fiscal year ended July 31, 1997, the Fund purchased bonds issued
by Bank America, The Bank of New York, Chase Manhattan Corp., Lehman Brothers
Holdings Inc., Morgan Stanley Group Inc. and PaineWebber Inc., and common stock
issued by Chase Manhattan Corp. At July 31, 1997, the Fund held a bond issued by
Lehman Brothers Holdings Inc. and common stock issued by Chase Manhattan Corp.
with market values of $6,033,060 and $17,034,375, respectively. These issuers
were among the ten brokers or the ten dealers which executed transactions for or
with the Fund in the largest dollar amounts during the fiscal year ended July
31, 1997.
    
 
THE DISTRIBUTOR
- --------------------------------------------------------------------------------
 
    As discussed in the Prospectus, shares of the Fund are distributed by Dean
Witter Distributors Inc. (the "Distributor"). The Distributor has entered into a
selected dealer agreement with DWR, which through its own sales organization
sells shares of the Fund. 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 exclusive distributor
of the Fund's shares and providing for the Distributor to bear distribution
expenses not borne by the Fund. By its terms, the Distribution Agreement has an
initial term ending April 30, 1998, and will remain in effect from year to year
thereafter if approved by the Trustees.
 
    The Distributor bears all expenses it may incur in providing services under
the Distribution Agreement. Such expenses include the payment of commissions for
sales of the Fund's shares and incentive compensation to account executives. The
Distributor also pays certain expenses in connection with the distribution of
the Fund's shares, including the costs of preparing, printing and distributing
advertising or promotional materials, and the costs of printing and distributing
prospectuses and supplements thereto used in connection with the offering and
sale of the Fund's shares. The Fund bears the costs of initial typesetting,
printing and distribution of prospectuses and supplements thereto to
shareholders. The Fund also bears the costs of registering the Fund and its
shares under federal securities laws and pays filing fees in accordance with
state securities laws. The Fund and 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
 
                                       28
<PAGE>
its obligations, the Distributor is not liable to the Fund or any of its
shareholders for any error of judgement 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 1.0% of the average daily net assets of Class A and
Class C, respectively, and, with respect to Class B, (i) 1.0% of the lesser of:
(a) the average daily aggregate gross sales of the Fund's Class B shares since
the implementation of the Plan on November 8, 1989 (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 implementation
of the Plan 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 attributable to shares issued, net of related shares redeemed, since the
implementation of the Plan; plus (ii) 0.25% of the average daily net assets of
Class B attributable to shares issued, net of related shares redeemed, prior to
implementation of the Plan. 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 approximately
$1,775,000, $1,662,000 and $1,683,000 in contingent deferred sales charges for
the fiscal years ended July 31, 1995, 1996 and 1997, respectively, none of which
was retained by the Distributor. These amounts were received from Class B only.
No front-end sales charges were received from Class A and no contingent deferred
sales charges were received from Class A or Class C for the fiscal period July
28 through July 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 0.25% of such Class's average daily net assets are
currently each characterized as a "service fee" under the Rules of the
Association of the National Association of Securities Dealers, 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 Trustees, including all of
the Trustees who are not "interested persons" of the Fund (as defined in the
Act) and who had or have no direct or indirect financial interest in the
operation of the Plan (the "Independent 12b-1 Trustees"), cast in person at a
meeting called for the purpose of voting on the Plan, on July 27, 1989, and by
the shareholders holding a majority, as defined in the Act, of the outstanding
shares of the Fund, at the Fund's Special Meeting of Shareholders held on
November 8, 1989. The Plan amended and restated the Fund's initial Plan of
Distribution which had been in effect from August 26, 1988 through November 7,
1989.
 
    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 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, also 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 December 19, 1995, the shareholders of the
Fund approved an amendment to the
 
                                       29
<PAGE>
Plan to permit payments to be made under the Plan with respect to distribution
expenses incurred in connection with the distribution of shares of an investment
company whose assets are acquired by the Fund in a tax-free reorganization. At
their meeting held on June 30, 1997, the Trustees, including a majority of the
Independent 12b-1 Trustees, approved amendments to the Plan to reflect the
multiple-class structure for the Fund, which took effect on July 28, 1997.
 
   
    Under the Plan and as required by Rule 12b-1, the Trustees receive and
review promptly after the end of each fiscal quarter a written report provided
by the Distributor of the amounts expended 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 July 31, 1997, of $12,491,604. This amount is equal to 0.89% of the
average daily net assets of Class B for the fiscal year and was calculated
pursuant to clauses (i)(a) and (ii) 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 July 31, 1997, Class A and Class C shares of
the Fund accrued payments under the Plan amounting to $1 and $6, respectively,
which amounts are equal to 0.25% and 1.0% 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 5.0% of the
amount sold (except as provided in the following sentence) and an annual
residual commission, currently a residual of up to 0.25% of the current value of
the respective accounts for which they are the account executives or dealers of
record in all cases. On orders of $1 million or more (for which no sales charge
was paid) or net asset value purchases by 401(k) plans or other
employer-sponsored plans qualified under Section 401(a) of the Internal Revenue
Code for which Dean Witter Trust FSB ("DWT") serves as Trustee or the 401(k)
Support Services Group of DWR serves as recordkeeper, 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 5.0% of the amount sold (except as
provided in the following sentence) and an annual residual commission, currently
a residual of up to 0.25% of the current value (not including reinvested
dividends or distributions) of the amount sold in all cases. In the case of
retirement plans qualified under Section 401(k) of the Internal Revenue Code and
other employer-sponsored plans qualified under Section 401(a) of the Internal
Revenue Code for which DWT serves as Trustee or the 401(k) Support Services
Group of DWR serves as recordkeeper, and which plans are opened on or after July
28, 1997, DWR compensates its account executives by paying them, from its own
funds, a gross sales credit of 3.0% of the amount sold.
    
 
    With respect to Class C shares, DWR compensates its account executives by
paying them, from its own funds, commissions for the sale of Class C shares,
currently a gross sales credit of up to 1.0% of the amount sold and an annual
residual commission, currently a residual of up to 1.0% of the current value of
the respective accounts for which they are the account executives of record.
 
    With respect to Class D shares other than shares held by participants in
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
 
                                       30
<PAGE>
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 share sales. The distribution fee
that the Distributor receives from the Fund under the Plan, in effect, offsets
distribution expenses incurred 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 sales 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
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 1.0%, in the case of Class C, of the average net assets of the respective
Class during the month. No interest or other financing charges, if any, incurred
on any distribution expenses on behalf of Class A and Class C will be
reimbursable under the Plan. With respect to Class A, in the case of all
expenses other than expenses representing the service fee, and, with respect to
Class C, in the case of all expenses other than expenses representing a gross
sales credit or a residual to account executives, such amounts shall be
determined at the beginning of each calendar quarter by the Trustees, including
a majority of the Independent 12b-1 Trustees. Expenses representing the service
fee (for Class A) or a gross sales credit or a residual to account executives
(for Class C) may be reimbursed without prior determination. In the event that
the Distributor proposes that monies shall be reimbursed for other than such
expenses, then in making quarterly determinations of the amounts that may be
reimbursed by the Fund, the Distributor will provide and the Trustees will
review a quarterly budget of projected distribution expenses to be incurred on
behalf of the Fund, together with a report explaining the purposes and
anticipated benefits of incurring such expenses. The Trustees will determine
which particular expenses, and the portions thereof, that may be borne by the
Fund, and in making such a determination shall consider the scope of the
Distributor's commitment to promoting the distribution of the Fund's Class A and
Class C shares.
    
 
   
    Each Class paid 100% of the amounts accrued under the Plan with respect to
that Class for the fiscal year ended July 31, 1997 to the Distributor. The
Distributor and DWR estimate that they have spent, pursuant to the Plan,
$91,860,398 on behalf of Class B since the inception of the Fund. It is
estimated that this amount was spent in approximately the following ways: (i)
3.25% ($2,989,043)--advertising and promotional expenses; (ii) 0.29% ($270,696)
printing of prospectuses for distribution to other than current shareholders;
and (iii) 96.46% ($88,600,659)--other expenses, including the gross sales credit
and the carrying charge, of which 7.64% ($6,770,173) represents carrying
charges, 30.83% ($27,313,322) represents commission credits to DWR branch
offices for payments of commissions to account executives, 46.36% ($41,072,562)
represents overhead and other branch office distribution-related expenses, and
15.17% ($13,444,602) represents excess distribution expenses of Dean Witter
Managed Assets Trust, the net assets of which were combined with those of the
Fund on December 22, 1995 pursuant to an
    
 
                                       31
<PAGE>
   
Agreement and Plan of Reorganization. The amounts accrued by Class A and Class C
for distribution during the fiscal period July 28 through July 31, 1997 were for
expenses which relate to compensation of sales personnel and associated overhead
expenses.
    
 
   
    In the case of Class B shares, at any given time, the expenses in
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 $37,067,710 as of
July 31, 1997. Because there is no requirement under the Plan that the
Distributor be reimbursed for all 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 distribution expenses 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 or any Trustee of the Fund who is not an
interested person of the Fund, as defined in the Act, had any direct or indirect
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 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, 1990 and will
continue from year to year thereafter, provided such continuance is approved
annually by a vote of the Trustees in the manner described above. Prior to the
Board's approval of amendments to the Plan to reflect the multiple-class
structure for the Fund, the most recent continuance of the Plan for one year,
until April 30, 1998, was approved by the Trustees of the Fund, including a
majority of the Independent 12b-1 Trustees, at a meeting of the Trustees held on
April 24, 1997. Prior to approving the continuation of the Plan, the Trustees
requested and received from the Distributor and reviewed all 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 of the shareholders of the
affected Class or Classes of the Fund, and all material amendments of the Plan
must also be approved by the Trustees in the manner described above. The Plan
may be terminated at any time, without payment of any penalty, by vote of a
majority of the Trustees who are not interested persons of the Fund and who have
no direct or indirect financial interest in the operation of the Plan, or by a
vote of a majority of the outstanding voting securities of the Fund (as defined
in the Act) on not more than thirty days' written notice to any other party to
the Plan. So long as the Plan is in effect, the election and nomination of
Independent 12b-1 Trustees shall be committed to the discretion of the
Independent 12b-1 Trustees.

DETERMINATION OF NET ASSET VALUE
- --------------------------------------------------------------------------------
 
    As stated in the Prospectus, short-term securities with remaining maturities
of sixty days or less at the time of purchase are valued at amortized cost,
unless the Trustees determine such does not reflect the securities' market
value, in which case these securities will be valued at their fair value as
determined by the Trustees. Other short-term debt securities will be valued on a
mark-to-market basis until such time as they reach a remaining maturity of sixty
days, whereupon they will be valued at amortized cost using their value on the
61st day unless the Trustees determine such does not reflect the securities'
market value, in which case these securities will be valued at their fair value
as determined by the Trustees. Listed options on debt securities are valued at
the latest sale price on the exchange on which they are listed unless no sales
of such options have taken place that day, in which case they will be valued at
the mean between their latest bid and asked prices. Unlisted options on debt
securities and all options on equity securities are valued at the mean between
their latest bid and asked prices. Futures are valued at the latest sale price
on the commodities exchange on which they trade unless the Trustees determine
such price does not reflect their market value, in which case they will be
valued at their fair value as determined by the Trustees. All other securities
and other assets are valued at their fair value as determined in good faith
under procedures established by and under the supervision of the Trustees.
 
    The net asset value per share for each Class of shares of the Fund is
determined once daily at 4:00 p.m. New York time (or, on days when the New York
Stock Exchange closes prior to 4:00 p.m., at such earlier time), on each day
that the New York Stock Exchange is open. The New York Stock Exchange currently
observes the following holidays: New Year's Day, Reverend Dr. Martin Luther
King, Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence Day,
Labor Day, Thanksgiving Day, and Christmas Day.
 
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 4.75% of
the offering price.
 
   
    The Distributor must be notified by the selected broker-dealer or the
shareholder at the time a purchase order is placed that the purchase qualifies
for the reduced charge under the Right of Accumulation. Similar notification
must be made in writing by the selected broker-dealer or shareholder when such
an order is placed by mail. The reduced sales charge will not be granted if: (a)
such notification is not furnished at the time of the order; or (b) a review of
the records of the Distributor or Dean Witter Trust FSB (the "Transfer Agent")
fails to confirm the investor's represented holdings.
    
 
    LETTER OF INTENT.  As discussed in the Prospectus, reduced sales charges are
available to investors who enter into a written Letter of Intent providing for
the purchase, within a thirteen-month period, of Class A shares of the Fund from
the Distributor or from a single Selected Broker-Dealer.
 
                                       33
<PAGE>
    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 employer-sponsored benefit plans, three years). However,
no CDSC will be imposed to the extent that the net asset value of the shares
redeemed does not exceed: (a) the current net asset value of shares purchased
more than six years (or, in the case of shares held by certain
employer-sponsored benefit plans, three years) prior to the redemption, plus (b)
the current net asset value of shares purchased through reinvestment of
dividends or distributions of the Fund or another 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 (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 employer-sponsored
benefit plans, three years) will be redeemed first. In the event the redemption
amount exceeds such increase in value, the next portion of the amount redeemed
will be the amount which represents the net asset value of the investor's shares
purchased more than six (three) years prior to the redemption and/or shares
purchased through reinvestment of dividends or distributions 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
employer-sponsored benefit 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 employer-sponsored benefit plans, three
years) of purchase which are in excess of these amounts and which redemptions do
not qualify for waiver of the CDSC, as described in the Prospectus.
 
LEVEL LOAD ALTERNATIVE--CLASS C SHARES
 
    Class C shares are sold without a sales charge but are subject to a CDSC of
1.0% on most redemptions made within one year after purchase, except in the
circumstances discussed in the Prospectus.

NO LOAD ALTERNATIVE--CLASS D SHARES
 
    Class D shares are offered without any sales charge on purchase or
redemption. Class D shares are offered only to those persons meeting the
qualifications set forth in the Prospectus.
 
SHAREHOLDER SERVICES
- --------------------------------------------------------------------------------
 
    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 the 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 Strategist Fund or in another Class of Dean Witter
Strategist Fund. Such investment will be made as described above for automatic
investment in shares of the applicable Class of the Fund, at the net asset value
per share of the selected 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 the same business day the
transfer of funds is effected (subject to any applicable sales charges). For
further information or to subscribe to EasyInvest, shareholders should contact
their DWR or other selected broker-dealer account executive or the Transfer
Agent.
    
 
                                       36
<PAGE>
    INVESTMENT OF DIVIDENDS OR DISTRIBUTIONS RECEIVED IN CASH.  As discussed in
the Prospectus, any shareholder who receives a cash payment representing a
dividend or capital gains distribution may invest such dividend or distribution
in shares of the applicable Class at net asset value, without the imposition of
a CDSC upon redemption, by returning the check or the proceeds to the Transfer
Agent within thirty days after the payment date. If the shareholder returns the
proceeds of a dividend or distribution, such funds must be accompanied by a
signed statement indicating that the proceeds constitute a dividend or
distribution to be invested. Such investment will be made at the net asset value
per share next determined after receipt of the check or the proceeds by the
Transfer Agent.
 
    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 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.
 
    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, or amounts credited to a shareholder's DWR or other
selected broker-dealer brokerage account, 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.
 
    DIRECT INVESTMENT THROUGH TRANSFER AGENT.  As discussed in the Prospectus, a
shareholder 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 Strategist Fund, 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,
 
                                       37
<PAGE>
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., Dean Witter High
Income Securities and Dean Witter National Municipal Trust, which are Dean
Witter Funds offered with a CDSC ("CDSC Funds"). Exchanges may be made after the
shares of the Fund acquired by purchase (not by exchange or dividend
reinvestment) have been held for thirty days. There is no waiting period for
exchanges of shares acquired by exchange or dividend reinvestment. An exchange
will be treated for federal income tax purposes the same as a repurchase or
redemption of shares, on which the shareholder may realize a capital gain or
loss.
 
    Any new account established through the Exchange Privilege will have the
same registration and cash dividend or dividend reinvestment plan as the present
account, unless the Transfer Agent receives written notification to the
contrary. For telephone exchanges, the exact registration of the existing
account and the account number must be provided.
 
    Any shares held in certificate form cannot be exchanged but must be
forwarded to the Transfer Agent and deposited into the shareholder's account
before being eligible for exchange. (Certificates mailed in for deposit should
not be endorsed.)
 
    As described below, and in the Prospectus under the caption "Purchase of
Fund Shares," a CDSC may be imposed upon a redemption, depending on a number of
factors, including the number of years from the time of purchase until the time
of redemption or exchange ("holding period"). When shares of a Dean Witter
Multi-Class Fund or any CDSC Fund are exchanged for shares of an Exchange Fund,
the exchange is executed at no charge to the shareholder, without the imposition
of the CDSC at the time of the exchange. During the period of time the
shareholder remains in the Exchange Fund (calculated from the last day of the
month in which the Exchange Fund shares were acquired), the holding period or
"year since purchase payment made" is frozen. When shares are redeemed out of
the Exchange Fund, they will be subject to a CDSC which would be based upon the
period of time the shareholder held shares in a Dean Witter Multi-Class Fund or
in a CDSC Fund. However, 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, if any, incurred
on or after that date which are attributable to those shares. Shareholders
acquiring shares of an Exchange Fund pursuant to this exchange privilege may
exchange those shares back into a Dean Witter Multi-Class Fund or a CDSC Fund
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 of a CDSC 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 Dean Witter Multi-Class Fund or in a CDSC
Fund. 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.
 
                                       38
<PAGE>
    When shares initially purchased in a Dean Witter Multi-Class Fund or in a
CDSC Fund are exchanged for shares of a Dean Witter Multi-Class Fund, shares of
a CDSC Fund, 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 on the CDSC schedule applicable to the
shares) prior to the exchange, (ii) originally acquired through reinvestment of
dividends or distributions 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. With
respect to exchanges, redemptions or repurchases, the Transfer Agent shall be
liable for its own negligence and not for the default or negligence of its
correspondents or for losses in transit. The Fund shall not be liable for any
default or negligence of the Transfer Agent, the Distributor or any selected
broker-dealer.
 
    The Distributor and any selected broker-dealer have authorized and appointed
the Transfer Agent to act as their agent in connection with the application of
proceeds of any redemption of Fund shares to the purchase of shares of any other
fund and the general administration of the Exchange Privilege. No commission or
discounts will be paid to the Distributor or any selected broker-dealer for any
transactions pursuant to this Exchange Privilege.
 
    Exchanges are subject to the minimum investment requirement and any other
conditions imposed by each fund. (The minimum initial investment for the
Exchange Privilege account of each Class is $5,000 for Dean Witter Liquid Asset
Fund Inc., Dean Witter Tax-Free Daily Income Trust, Dean Witter New York
Municipal Money Market Trust and Dean Witter California Tax-Free Daily Income
Trust, although those funds may, at their discretion, accept initial investments
of as low as $1,000. The minimum initial investment for the Exchange Privilege
account of each Class is $10,000 for Dean Witter Short-Term U.S. Treasury Trust
although that fund may, in its discretion, accept initial investments as low as
$5,000. The minimum initial investment for the Exchange Privilege account of
each Class is $5,000 for Dean Witter
 
                                       39
<PAGE>
Special Value Fund. The minimum initial investment for the Exchange Privilege
account of each Class of 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
Exchange Funds 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 re-
stricted, (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") 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.
 
    Whether certificates are held by the shareholder or shares are held in a
shareholder's account, if the proceeds are to be paid to any person other than
the record owner, or if the proceeds are to be paid to a corporation (other than
the Distributor or a selected broker-dealer for the account of the shareholder),
partnership, trust or fiduciary, or sent to the shareholder at an address other
than the registered address, signatures must be guaranteed by an eligible
guarantor acceptable to the Transfer Agent (shareholders should contact the
Transfer Agent for a determination as to whether a particular institution is
such an eligible guarantor). A stock power may be obtained from any dealer or
commercial bank. The Fund may change the signature guarantee requirements from
time to time upon notice to shareholders, which may be by means of a 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
 
                                       40
<PAGE>
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. 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. 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, 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). 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 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 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 at the net
asset value next determined after a reinstatement request, together with the
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 will notify shareholders that, following an election by the
Fund, the shareholders will be required to include such undistributed gains in
determining their taxable income and may claim their share of the tax paid by
the Fund as a credit against their individual federal income tax.

    Because the Fund intends to distribute all of its net investment income and
net capital gains to shareholders and otherwise continue to qualify as a
regulated investment company under Subchapter M of the Internal Revenue Code, it
is not expected that the Fund will be required to pay any federal income tax.
Shareholders will normally have to pay federal income taxes, and any state
income taxes, on the dividends and distributions they receive from the Fund.
Such dividends and distributions, to the extent that they are derived from net
investment income or net 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 calendar
year.
 
    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 capital gains or losses.
 
    Gains or losses on the Fund's transactions, if any, in futures and
non-equity options generally are treated as 60% long-term and 40% short-term
capital gains or losses. When the Fund engages in 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.
 
    One of the requirements for the Fund to remain qualified as a regulated
investment company is that less than 30% of its gross income be derived from
gains from the sale or other disposition of securities held for less than three
months. Accordingly, the Fund may be restricted in the writing of options on
securities held for less than three months, in the writing of options which
expire in less than three months, and in effecting closing transactions with
respect to call or put options which have been written or purchased less than
three months prior to such transactions. The Fund may also be restricted in its
ability to engage in transactions involving futures contracts.
 
    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.
 
    Under current federal law, the Fund will receive net investment income in
the form of interest by virtue of holding Treasury bills, notes and bonds, and
will recognize income attributable to it from holding zero coupon Treasury
securities. 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
payment in cash on the security during the year. As an investment company, the
Fund must pay out substantially all of its net investment income each year.
Accordingly, the Fund, to the extent it invests in zero coupon Treasury
securities, may be required to pay out as an income distribution each year an
amount which is greater than the total amount of cash receipts of interest the
Fund actually received. Such distributions will be made from the available cash
of the Fund or by liquidation of portfolio securities if necessary. If a
distribution or cash necessitates the liquidation of portfolio securities, the
Investment Manager will select which securities to sell. The Fund may realize a
gain or loss from such sales. In the event the Fund realizes net capital gains
from such transactions, its shareholders may receive a larger capital gain
distribution, if any, than they would in the absence of such transactions.
 
    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 for which amortization 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 in accordance with the provisions of the Internal Revenue Code.
Realized gains and losses on security transactions are determined on the
identified cost method.
 
                                       42
<PAGE>
    Any dividend or capital gains distribution received by a shareholder from
any investment company will have the effect of reducing the net asset value of
the shareholder's stock in that company by the exact amount of the dividend or
capital gains distribution. Furthermore, capital gains distributions and
dividends are subject to federal income taxes. If the net asset value of the
shares should be reduced below a shareholder's cost as a result of the payment
of dividends or the distribution of realized net long-term capital gains, such
payment or distribution would be in part a return of the shareholder's
investment to the extent of such reduction below the shareholder's cost, but
nonetheless would be fully taxable. Therefore, an investor should consider the
tax implications of purchasing Fund shares immediately prior to a distribution
record date.
 
    Dividend payments will be eligible for the federal dividends received
deduction available to the Fund's corporate shareholders only to the extent the
aggregate dividends received by the Fund would be eligible for the deduction if
the Fund were the shareholder claiming the dividends received deduction. The
amount of dividends paid by the Fund which may qualify for the dividends
received deduction is limited to the aggregate amount of qualifying dividends
which the Fund derives from its portfolio investments which the Fund has held
for a minimum period, usually 46 days. Any distributions made by the Fund will
not be eligible for the dividends received deduction with respect to shares
which are held by the shareholder for 45 days or less. Any long-term capital
gain distributions will also not be eligible for the dividends received
deduction. The ability to take the dividends received deduction will also be
limited in the case of a Fund shareholder which incurs or continues indebtedness
which is directly attributable to its investment in the Fund.
 
    After the end of the 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
"total return" in advertisements and sales literature. These figures are
computed separately for Class A, Class B, Class C and Class D shares. 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 total returns of Class B for the fiscal year ended July 31, 1997, for the
five year period ended July 31, 1997 and for the period from October 31, 1988
(commencement of operations) through July 31, 1997 were 24.73%, 13.09% and
14.26%, respectively.
    
 
   
    For periods of less than one year, the Fund quotes its total return on a
non-annualized basis. Accordingly, the Fund may compute its aggregate total
return for each of Class A, Class 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
    
 
                                       43
<PAGE>
   
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 July 31,
1997 were -3.45%, 0.90% and 1.90% for Class A, Class C and Class D,
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 July 31,
1997, for the five year period ended July 31, 1997 and for the period October
31, 1988 through July 31, 1997 were 29.73%, 13.33% and 14.26%, 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 on the foregoing
calculation, the total returns for Class B for the fiscal year ending July 31,
1997, for the five year period ended July 31, 1997 and for the period October
31, 1988 through July 31, 1997 were 29.73%, 86.95% and 220.97%, respectively.
Based on the foregoing calculations, the total returns for Class A, Class C and
Class D for the period July 28 through July 31, 1997 were 1.90%, 1.90% and
1.90%, 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
$9,475, $48,000 and $97,000 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 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 to the following amounts at July 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.
    
 
                                       44
<PAGE>
    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 (which would be used to distinguish among the rights of
different categories of shareholders, as might be required by future regulations
or other unforeseen circumstances). The Trustees have not authorized any such
additional series or classes of shares other than as set forth in the
Prospectus.
 
    The Declaration of Trust provides that no Trustee, officer, employee or
agent of the Fund is liable to the Fund or to a shareholder, nor is any Trustee,
officer, employee or agent liable to any third persons in connection with the
affairs of the Fund, except as such liability may arise from his/her or its own
bad faith, willful misfeasance, gross negligence, or reckless disregard of his
his/her or its 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 Fund is authorized to issue an unlimited number of shares of beneficial
interest. The Fund shall be of unlimited duration subject to the provisions in
the Declaration of Trust concerning termination by action of the shareholders.

DEAN WITTER STRATEGIST FUND
NOTES TO FINANCIAL STATEMENTS JULY 31, 1997
 
1. ORGANIZATION AND ACCOUNTING POLICIES
 
Dean Witter Strategist Fund (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 investment objective is to maximize
the total return of its investments. The Fund seeks to achieve its objective by
actively allocating its assets among major asset categories of equity and
fixed-income securities and money market instruments. The Fund was organized as
a Massachusetts business trust on August 5, 1988 and commenced operations on
October 31, 1988. On July 28, 1997, the Fund commenced offering three additional
classes of shares, with the then current shares, other than shares which were
purchased prior to November 8, 1989 (and with respect to such shares, certain
shares acquired through reinvestment of dividends and capital gains
distributions (collectively the "Old Shares")) and shares held by certain
employee benefit plans established by Dean Witter Reynolds Inc. and its
affiliate, SPS Transaction Services, Inc., designated as Class B shares. The Old
Shares and shares held by those employee benefit plans prior to July 28, 1997
have been designated Class D shares.
 
The Fund offers Class A shares, Class B shares, Class C shares and Class D
shares. The four classes are substantially the same except that most Class A
shares are subject to a sales charge imposed at the time of purchase, some Class
A shares, and most Class B shares and Class C shares are subject to a contingent
deferred sales charge imposed on shares redeemed within one year, six years and
one year, respectively. Class D shares are not subject to a sales charge.
Additionally, Class A shares, Class B shares and Class C shares incur
distribution expenses.
 
The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts and disclosures. Actual results could differ from
those estimates.
 
The following is a summary of significant accounting policies:
 
A. VALUATION OF INVESTMENTS -- (1) an equity security listed or traded on the
New York, American 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); (2) all other portfolio securities for which
over-the-counter market quotations are readily available are valued at the
latest available bid price prior to the time of valuation; (3) when market
quotations are not readily available, including circumstances under which it is
determined by Dean Witter
 
                                       55

DEAN WITTER STRATEGIST FUND
NOTES TO FINANCIAL STATEMENTS JULY 31, 1997, CONTINUED
 
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 of the Fund's
portfolio securities may be valued by an outside pricing service approved by the
Trustees. The pricing service may utilize a matrix system incorporating security
quality, maturity and coupon as the evaluation model parameters, and/or research
and evaluations by its staff, including review of broker-dealer market price
quotations, if available, in determining what it believes is the fair valuation
of the portfolio securities valued by such pricing service; and (5) short-term
debt securities having a maturity date of more than sixty days at time of
purchase are valued on a mark-to-market basis until sixty days prior to maturity
and thereafter at amortized cost based on their value on the 61st day.
Short-term debt securities having a maturity date of sixty days or less at the
time of purchase are valued at amortized cost.
 
B. ACCOUNTING FOR INVESTMENTS -- Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). Realized gains and
losses on security transactions are determined by the identified cost method.
Discounts are accreted over the life of the respective securities. Dividend
income and other distributions are recorded on the ex-dividend date. Interest
income is accrued daily.
 
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 the income is earned or expenses and
realized and unrealized gains and losses are incurred. Distribution fees are
charged directly to the respective class.
 
C. 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.
 
D. 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 the Fund pays the Investment
Manager a management fee, accrued daily and payable monthly, by applying the
following annual rates to the net assets of the Fund determined at the close of
each business day: 0.60% to the portion of daily net assets not exceeding $500
million; 0.55% to the portion of daily net assets exceeding $500 million but not
exceeding $1 billion; 0.50% to the portion of daily net assets exceeding $1
billion but not exceeding $1.5 billion; and 0.475% to the portion of daily net
assets exceeding $1.5 billion.
 
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 -- 0.25% of the average
daily net assets of Class A; (ii) Class B -- 1.0% of the lesser of: (a) the
average daily aggregate gross sales of the Class B shares since the
implementation of the Plan on November 8, 1989 (not including reinvestment of
dividend or capital gain distributions) less the average daily aggregate net
asset value of the Class B shares redeemed since the Fund's implementation of
the Plan 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 --
1.0% of the average daily net assets of Class C. In the case of Class A shares,
amounts paid under the Plan are paid to the Distributor for services provided.
In the case of Class B and Class C shares, amounts paid under the Plan are paid
to the Distributor for services

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 $37,067,710 at July 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 1.0% of the average daily
net assets of Class A or Class C, respectively, will not be reimbursed by the
Fund through payments in any subsequent year, except that expenses representing
a gross sales credit to account executives may be reimbursed in the subsequent
calendar year. For the period ended July 31, 1997, the distribution fee was
accrued for Class A shares and Class C shares at the annual rate of 0.25% and
1.0%, respectively.
 
The Distributor has informed the Fund that for the year ended July 31, 1997, it
received contingent deferred sales charges from certain redemptions of the
Fund's Class B shares of approximately $1,683,000. The shareholders pay such
charges which are not an expense of the Fund.

REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE SHAREHOLDERS AND TRUSTEES
OF DEAN WITTER STRATEGIST FUND
 
In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Dean Witter Strategist Fund (the
"Fund") at July 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 July 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
 
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.
 
    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.
 
                            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 categories.
 
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
 
                                       65
<PAGE>
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.
 
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.
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.
 
                            COMMERCIAL PAPER RATINGS
 
    Standard and Poor's commercial paper rating is a current assessment of the
likelihood of timely payment of debt having an original maturity of no more than
365 days. The commercial paper rating is not a recommendation to purchase or
sell a security. The ratings are based upon current information furnished by the
issuer or obtained by S&P 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.
 
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.
   
          Pursuant to Section 5.2 of the Registrant's Declaration of Trust 
and paragraph 8 of the Registrant's Investment Management Agreement, 


                                          2
<PAGE>


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.

     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 to the

address as it appears on the records of the Trust.

business. In the absence of a quorum, the Shareholders present or represented 
by proxy and entitled to vote thereat shall have power to adjourn the meeting 
from time to time. Any adjourned meeting may be held as adjourned without

the Trust and for the fractional portion of one vote for each fractional 
Share entitled to vote so registered in his name on the records of the Trust 
on the date fixed as the record date for the determination of Shareholders 
entitled to vote at such meeting. No proxy shall be valid after eleven months 
from its date, unless otherwise provided in the proxy. At all meetings of 
Shareholders, unless the voting is conducted by inspectors, all questions 
relating to the qualification of voters and the validity of proxies and the 
acceptance or rejection of votes shall be decided by the chairman of the 
meeting. Pursuant to a resolution of a majority of the Trustees, proxies may 
be solicited in the name of one or more Trustees or Officers of the Trust. 

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

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

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

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

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

                                   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 President, the President, any Vice 
President or the Treasurer or by any one or more officers or agents of the 
Trust as shall be designated for that purpose by vote of the Trustees; 
notwithstanding the above, nothing in this Section 4.7 shall be deemed to 
preclude the electronic authorization, by designated persons, of the Trust's 
Custodian (as described herein in Section 9.1) to transfer assets of the 
Trust, as provided for herein in Section 9.1. 

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

                                         3           
<PAGE>

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

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

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

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

         (2) The determination shall be made: 

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

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

             (iii) By the Shareholders. 

         (3) Notwithstanding any provision of this Section 4.8, no person shall
     be entitled to indemnification for any liability, whether or not there is 
     an adjudication of liability, arising by reason of willful misfeasance, 
     bad faith, gross negligence, or reckless disregard of duties as described
     in Section 17(h) and (i) of the Investment Company Act of 1940 
     ("disabling conduct"). A person shall be deemed not liable by reason of
     disabling conduct if, either: 
 
             (i) a final decision on the merits is made by a court or other body
    before whom the proceeding was brought that the person to be indemnified 
    ("indemnitee") was not liable by reason of disabling conduct; or 

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

                                         4           
<PAGE>

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

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

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

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

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

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

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

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

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

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

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

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

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

                                  ARTICLE V 
                                  COMMITTEES 

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

                                         5           
<PAGE>

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

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

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

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

                                  ARTICLE VI

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 
the other executive officers need be a Trustee. Two or more offices, except 
those of President and any Vice President, may be held by the same person, 
but no officer shall execute, acknowledge or verify any instrument in more 
than one capacity. The executive officers of the Trust shall be elected 
annually by the Trustees and each executive officer so elected shall hold

appoint, such other officers and agents as the Trustees shall at any time or 
from time to time deem advisable. 

     SECTION 6.3. TERM AND REMOVAL AND VACANCIES. Each officer of the Trust 
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 Chairman to the 
extent provided by the Trustees with respect to officers appointed by the 
President.

between themselves and the Trust, shall have such authority and perform such 
duties in the management of the Trust as may be provided in or pursuant to 
these By-Laws, or to the extent not so provided, as may be prescribed by the

number and shall have such titles as may be determined from time to time by

meetings of the Shareholders and special meetings of the Trustees, and shall 
perform such other duties and have such powers as the Trustees, or the 
President, may from time to time prescribe. He shall keep in safe custody the 
seal of the Trust and affix or cause the same to be affixed to any instrument 
requiring it, and, when so affixed, it shall be attested by his signature or 
by the signature of an Assistant Secretary. 

     SECTION 6.11. THE ASSISTANT SECRETARIES. The Assistant Secretary, or, if 
there be more than one, the Assistant Secretaries in the order determined by

     SECTION 6.12. THE TREASURER. The Treasurer shall be the chief financial 
officer of the Trust. He shall keep or cause to be kept full and accurate 
accounts of receipts and disbursements in books belonging to the Trust, and 
he shall render to the Trustees and the President, whenever any of them

     SECTION 6.13. THE ASSISTANT TREASURERS. The Assistant Treasurer, or, if 
there shall be more than one, the Assistant Treasurers in the order 
determined by the Trustees or the President, shall, in the absence or 
disability of the Treasurer, perform the duties and exercise the powers of 
the Treasurer and shall perform such other duties and have such other powers 
as the Trustees, or the President, may from time to time prescribe. 

     SECTION 6.14. DELEGATION OF DUTIES. Whenever an officer is absent or 
disabled, or whenever for any reason the Trustees may deem it desirable, the 
Trustees may delegate the powers and duties of an officer or officers to any

                                 ARTICLE VII 
                         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

time to time determine. 

                                         7           
<PAGE>

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

         (1) to receive and hold the securities owned by the Trust and deliver

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.

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.

                               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.

                                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

record date for the purpose of determining Shareholders entitled to notice 
of, or to vote at, any meeting of Shareholders, or Shareholders entitled to 
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. Such 
date, in any case, shall be not more than ninety (90) days, and in case of a 
meeting of Shareholders not less than ten (10) days, prior to the date on 
which particular action requiring such determination of Shareholders is to be

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 such meeting. 

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

   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. 

                                9

     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 Strategist Fund, dated 
August 4, 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 
Strategist Fund refers to the Trustees under the Declaration collectively as
