DECEMBER 26, 1996
    
 
              Dean Witter Federal Securities Trust (the "Fund") is an open-end
diversified management investment company whose investment objective is to earn
a high level of current income. The Fund will seek to achieve its investment
objective by investing primarily in debt securities issued by the U.S.
Government, its agencies or instrumentalities, including mortgage-backed
securities, and by writing covered call and put options against such securities.
The Fund may also purchase options on such securities to effect closing
transactions. In addition, to hedge the Fund's portfolio of securities against
changes in prevailing interest rates, the Fund may purchase put options on U.S.
Government securities and engage in transactions involving interest rate futures
contracts and options on such contracts. Shares of the Fund are not issued,
insured or guaranteed, as to value or yield, by the U.S. Government, its
agencies or instrumentalities.
 
               Shares of the Fund are continuously offered at net asset value
without the imposition of a sales charge. However, redemptions and/ or
repurchases are subject in most cases to a contingent deferred sales charge,
scaled down from 5% to 1% of the amount redeemed, if made within six years of
purchase, which charge will be paid to the Fund's Distributor, Dean Witter
Distributors Inc. (See "Redemptions and Repurchases-- Contingent Deferred Sales
Charge.") In addition, the Fund pays the Distributor a Rule 12b-1 distribution
fee pursuant to a Plan of Distribution at the annual rate of 0.85% of the lesser
of (i) the average daily aggregate net sales or (ii) the average daily net
assets of the Fund. (See "Purchase of Fund Shares--Plan of Distribution.")
 
   
               This Prospectus sets forth concisely the information you should
know before investing in the Fund. It should be read and retained for future

- ----------------------------------------------------------------------------------------------------------------------
Offering          At net asset value without sales charge (see page 15). Shares redeemed within six years of purchase

Purchase          subsequent investments, $100 (see page 15).
- ----------------------------------------------------------------------------------------------------------------------
Investment        The investment objective of the Fund is to earn a high level of current income.
Objective
- ----------------------------------------------------------------------------------------------------------------------
Investment        Dean Witter InterCapital Inc. ("InterCapital"), the Investment Manager of the Fund, and its wholly-
Manager           owned subsidiary, Dean Witter Services Company, Inc., serve in various investment management,
                  advisory, management and administrative capacities to 100 investment companies and other portfolios
                  with assets of approximately $91 billion at November 30, 1996 (see page 5).
- ----------------------------------------------------------------------------------------------------------------------
Management        The Investment Manager receives a monthly fee at the annual rate of 0.55% of the Fund's daily net
Fee               assets not exceeding $1 billion, scaled down at various asset levels to 0.35% of the Fund's daily
                  net assets on assets exceeding $12.5 billion (see page 5).
- ----------------------------------------------------------------------------------------------------------------------
Dividends and     Dividends from net investment income are declared daily and paid monthly. Capital gains
Distributions     distributions are paid at least annually. Dividends and capital gains distributions are
                  automatically reinvested in additional shares at net asset value unless the shareholder elects to
                  receive cash (see pages 17 and 22).
- ----------------------------------------------------------------------------------------------------------------------
Distributor and   Dean Witter Distributors Inc. (the "Distributor"). The Distributor receives from the Fund a
Distribution Fee  distribution fee accrued daily and paid monthly at the rate of 0.85% per annum of the lesser of (i)
                  the Fund's average daily aggregate net sales or (ii) the Fund's average daily net assets. This fee
                  compensates the Distributor for the services provided in distributing shares of the Fund and for
                  sales-related expenses. The Distributor also receives the proceeds of any contingent deferred sales
                  charges (see pages 16 and 20).
- ----------------------------------------------------------------------------------------------------------------------
Redemption--      Shares are redeemable by the shareholder at net asset value. An account may be involuntarily
Contingent        redeemed if the total value of the account is less than $100 or, if the account was opened through
Deferred Sales    EasyInvest-SM-, if after twelve months the shareholder has invested less than $1,000 in the account.
Charge            Although no commission or sales load is imposed upon the purchase of shares, a contingent deferred
                  sales charge (scaled down from 5% to 1%) is imposed on any redemption of shares if after such
                  redemption the aggregate current value of an account with the Fund falls below the aggregate amount
                  of the investor's purchase payments made during the six years preceding the redemption. However,
                  there is no charge imposed on redemption of shares purchased through reinvestment of dividends or
                  distributions (see pages 20-22).
- ----------------------------------------------------------------------------------------------------------------------
Special Risk      The net asset value of the Fund's shares will fluctuate with changes in the market value of its
Considerations    portfolio securities. The Fund's yield will also vary based on the yield of the Fund's portfolio
                  securities. The Fund may purchase and write options on debt instruments, in both exchange-listed and
                  over-the-counter transactions, and engage in transactions involving futures contracts and options
                  thereon. In addition, the Fund may borrow money and thereby leverage its securities investments (in
                  an amount up to 25% of the Fund's total assets) and purchase securities on a when-issued and delayed
                  delivery and firm commitment basis. These investments may involve special risks (see pages 5-14).

THE FUND AND ITS MANAGEMENT
- --------------------------------------------------------------------------------
 
    Dean Witter Federal Securities Trust (the "Fund") is an open-end diversified
management investment company. The Fund is a trust of the type commonly known as
a "Massachusetts business trust" and was organized under the laws of
Massachusetts on November 20, 1986.
 
    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 Dean Witter, Discover & Co. ("DWDC"), a
balanced financial services organization providing a broad range of nationally
marketed credit and investment products.
 
   
    InterCapital and its wholly-owned subsidiary, Dean Witter Services Company
Inc., serve in various investment management, advisory, management and
administrative capacities to 100 investment companies, thirty of which are
listed on the New York Stock Exchange, with combined total assets of
approximately $3.1 billion at November 30, 1996. The Investment Manager also
manages portfolios of pension plans, other institutions and individuals which
aggregated approximately $87.9 billion at such date.
    
 
    The Fund has retained the Investment Manager to provide administrative
services, manage its business affairs and manage the investment of the Fund's
assets, including the placing of orders for the purchase and sale of portfolio
securities. InterCapital has retained Dean Witter Services Company Inc. to
perform the aforementioned administrative services for the Fund.
 
    The Fund's Trustees review the various services provided by or under the
direction of the Investment Manager to ensure that the Fund's general investment
policies and programs are being properly carried out and that administrative
services are being provided to the Fund in a satisfactory manner.
 
   
    As full compensation for the services and facilities furnished to the Fund
and for expenses of the Fund assumed by the Investment Manager, the Fund pays
the Investment Manager monthly compensation calculated daily by applying the
following annual rates to the Fund's net assets determined as of the close of
each business day: 0.55% of the portion of the Fund's daily net assets not
exceeding $1 billion, scaled down at various asset levels to 0.35% of the
portion of daily net assets exceeding $12.5 billion. For the fiscal year ended
October 31, 1996, the Fund accrued total compensation to the Investment Manager
amounting to 0.55% of the Fund's average daily net assets and the Fund's total
expenses amounted to 1.53% of the Fund's average daily net assets.
    
 
INVESTMENT OBJECTIVE AND POLICIES
- --------------------------------------------------------------------------------
 
    The investment objective of the Fund is to earn a high level of current
income. There can be no assurance that the investment objective will be
achieved. This objective is fundamental and cannot be changed without
shareholder approval. The following policies may be changed by the Board of
Trustees without shareholder approval.
 
    The Fund will seek to achieve its objective primarily by investing at least
65% of its total assets in U.S. Government securities (including such
 
securities purchased on a when-issued, delayed delivery or firm commitment
basis). 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.
 
                                       5
<PAGE>
   (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.
 
    The Fund is not limited as to the maturities of the U.S. Government
securities in which it may invest. For a discussion of the risks of investing in
such securities (including such securities purchased on a when-issued, delayed
delivery or firm commitment basis and zero coupon securities), see "Risk
Considerations" below.
 
    MORTGAGE-BACKED SECURITIES.  The Fund may invest in fixed-rate and
adjustable rate U.S. mortgage-backed securities ("Mortgage-Backed Securities").
There are currently three basic types of U.S. Mortgage-Backed Securities: (i)
those issued or guaranteed by the U.S. Government or one of its agencies or
instrumentalities, such as GNMA, FNMA and FHLMC (securities issued by GNMA, but
not those issued by FNMA or FHLMC, are backed by the "full faith and credit" of
the United States); (ii) those issued by private issuers that represent an
interest in or are collateralized by Mortgage-Backed Securities issued or
guaranteed by the U.S. Government or one of its agencies or instrumentalities;
and (iii) those issued by private issuers that represent an interest in or are
collateralized by whole mortgage loans or Mortgage-Backed Securities without a
government guarantee but usually having some form of private credit enhancement.
 
    The Fund will invest in mortgage pass-through securities representing
participation interests in pools of residential mortgage loans originated by
U.S. governmental or private lenders such as banks, broker-dealers and financing
corporations and guaranteed, to the extent provided in such securities, by the
U.S. Government or one of its agencies or instrumentalities. Such securities,
which are ownership interests in the underlying mortgage loans, differ from
conventional debt securities, which provide for periodic payment of interest in
fixed amounts (usually semi-annually) and principal payments at maturity or on
specified call dates. Mortgage pass-through securities provide for monthly
payments that are a "pass-through" of the monthly interest and principal
payments (including any prepayments) made by the individual borrowers on the
pooled mortgage loans, net of any fees paid to the guarantor of such securities
and the servicer of the underlying mortgage loans.
 
    The guaranteed mortgage pass-through securities in which the Fund may invest
include those issued or guaranteed by GNMA, FNMA and FHLMC. GNMA certificates
are direct obligations of the U.S. Government and, as such, are backed by the
"full faith and credit" of the United States. FNMA and FHLMC certificates are
not backed by the full faith and credit of the United States but, as noted
above, the issuing agency or instrumentality has the right to borrow, to meet
its obligations, from an existing line of credit with the U.S. Treasury. The
U.S.
 
                                       6
<PAGE>
Treasury has no legal obligation to provide such line of credit and may choose
not to do so.
 
    Certificates for Mortgage-Backed Securities evidence an interest in a
specific pool of mortgages. These certificates are, in most cases, "modified
pass-through" instruments, wherein the issuing agency guarantees the payment of
principal and interest on mortgages underlying the certificates, whether or not
such amounts are collected by the issuer on the underlying mortgages.
 
    ADJUSTABLE RATE MORTGAGE SECURITIES.  The Fund may also invest in adjustable
rate mortgage securities ("ARMs"), which are pass-through mortgage securities
collateralized by mortgages with adjustable rather than fixed rates. ARMs
eligible for inclusion in a mortgage pool generally provide for a fixed initial
mortgage interest rate for either the first three, six, twelve or thirteen
scheduled monthly payments. Thereafter, the interest rates are subject to
periodic adjustment based on changes to a designated benchmark index.
 
    ARMs contain maximum and minimum rates beyond which the mortgage interest
rate may not vary over the lifetime of the security. In addition, certain ARMs
provide for additional limitations on the maximum amount by which the mortgage
interest rate may adjust for any single adjustment period. Alternatively,
certain ARMs contain limitations on changes in the required monthly payment. In
the event that a monthly payment is not sufficient to pay the interest accruing
on an ARM, any such excess interest is added to the principal balance of the
mortgage loan, which is repaid through future monthly payments. If the monthly
payment for such an instrument exceeds the sum of the interest accrued at the
applicable mortgage interest rate and the principal payment required at such
point to amortize the outstanding principal balance over the remaining term of
the loan, the excess is utilized to reduce the then outstanding principal
balance of the ARM.
 
    PRIVATE MORTGAGE PASS-THROUGH SECURITIES. The Fund may invest in private
mortgage pass-through securities, which are structured similarly to the GNMA,
FNMA and FHLMC mortgage pass-through securities and are issued by originators of
and investors in mortgage loans, including savings and loan associations,
mortgage banks, commercial banks, investment banks and special purpose
subsidiaries of the foregoing. These securities usually are backed by a pool of
conventional fixed rate or adjustable rate mortgage loans. Since private
mortgage pass-through securities typically are not guaranteed by an entity
having the credit status of GNMA, FNMA and FHLMC, such securities generally are
structured with one or more types of credit enhancement.
 
    COLLATERALIZED MORTGAGE OBLIGATIONS AND MULTICLASS PASS-THROUGH
SECURITIES.  The Fund may invest in collateralized mortgage obligations or
"CMOs," which are debt obligations collateralized by mortgage loans or mortgage
pass-through securities. Typically, CMOs are collateralized by GNMA, FNMA or
FHLMC certificates, but also may be collateralized by whole loans or private
mortgage pass-through securities (such collateral collectively hereinafter
referred to as "Mortgage Assets"). Multiclass pass-through securities are equity
interests in a trust composed of Mortgage Assets. Payments of principal of and
interest on the Mortgage Assets, and any reinvestment income thereon, provide
the funds to pay debt service on the CMOs or make scheduled distributions on the
multiclass pass-through securities. CMOs may be issued by agencies or
instrumentalities of the U.S. government, or by private originators of, or
investors in, mortgage loans, including savings and loan associations, mortgage
banks, commercial banks, investment banks and special purpose subsidiaries of
the foregoing. The issuer of a series of CMOs may elect to be treated as a Real
Estate Mortgage Investment Conduit ("REMIC"). REMICs include governmental and/or
private entities that issue a fixed pool of mortgages secured by an interest in
real property. REMICs are similar to CMOs in that they issue multiple classes of
securities but, unlike CMOs, which are required to be structured as debt
securities, REMICs may be structured as indirect ownership interests in the
underlying assets of the REMICs themselves. However, there are no effects on the
Fund from investing in CMOs issued by entities that have elected to be treated
as REMICs,
 
                                       7
<PAGE>
and all future references to CMOs shall also be deemed to include REMICs. In
addition, in reliance upon an interpretation by the staff of the Securities and
Exchange Commission, the Fund may invest without limitation in CMOs and other
Mortgage-Backed Securities which are not by definition excluded from the
provisions of the Act, and which have obtained exemptive orders from such
provisions from the Securities and Exchange Commission.
 
    In a CMO, a series of bonds or certificates is issued in multiple classes.
Each class of CMOs, often referred to as a "tranche," is issued at a specific
fixed or floating coupon rate and has a stated maturity or final distribution
date. Principal prepayments on the Mortgage Assets may cause the CMOs to be
retired substantially earlier than their stated maturities or final distribution
dates. Interest is paid or accrues on all classes of the CMOs on a monthly,
quarterly or semi-annual basis. Certain CMOs may have variable or floating
interest rates and others may be stripped (securities which provide only the
principal or interest feature of the underlying security).
 
    The principal of and interest on the Mortgage Assets may be allocated among
the several classes of a CMO series in a number of different ways. Generally,
the purpose of the allocation of the cash flow of a CMO to the various classes
is to obtain a more predictable cash flow to the individual tranches than exists
with the underlying collateral of the CMO. As a general rule, the more
predictable the cash flow is on a CMO tranche, the lower the anticipated yield
will be on that tranche at the time of issuance relative to prevailing market
yields on Mortgage-Backed Securities. As part of the process of creating more
predictable cash flows on most of the tranches in a series of CMOs, one or more
tranches generally must be created that absorb most of the volatility in the
cash flows on the underlying mortgage loans. The yields on these tranches are
generally higher than prevailing market yields on Mortgage-Backed Securities
with similar maturities. As a result of the uncertainty of the cash flows of
these tranches, the market prices of and yield on these tranches generally are
more volatile.
 
    The Fund also may invest in, among other things, parallel pay CMOs and
Planned Amortization Class CMOs ("PAC Bonds"). Parallel pay CMOs are structured
to provide payments of principal on each payment date to more than one class.
These simultaneous payments are taken into account in calculating the stated
maturity date or final distribution date of each class which, as with other CMO
structures, must be retired by its stated maturity date or final distribution
date but may be retired earlier. PAC Bonds generally require payments of a
specified amount of principal on each payment date. PAC Bonds always are
parallel pay CMOs with the required principal payment on such securities having
the highest priority after interest has been paid to all classes.
 
    TYPES OF CREDIT ENHANCEMENT.  Mortgage-Backed Securities are often backed by
a pool of assets representing the obligations of a number of different parties.
To lessen the effect of failures by obligors on underlying assets to make
payments, those securities may contain elements of credit support, which fall
into two categories: (i) liquidity protection and (ii) protection against losses
resulting from ultimate default by an obligor on the underlying assets.
Liquidity protection refers to the provision of advances, generally by the
entity administering the pool of assets, to ensure that the receipt of payments
on the underlying pool occurs in a timely fashion. Protection against losses
resulting from default ensures ultimate payment of the obligations on at least a
portion of the assets in the pool. This protection may be provided through
guarantees, insurance policies or letters of credit obtained by the issuer or
sponsor from third parties, through various means of structuring the transaction
or through a combination of such approaches. The degree of credit support
provided for each issue is generally based on historical information respecting
the level of credit risk associated with the underlying assets. Delinquencies or
losses in excess of those anticipated could adversely affect the return on an
investment in a security. The Fund will not pay any fees for credit support,
although the existence of credit support may increase the price of a security.

<PAGE>
    For a discussion of the risks of investing in Mortgage-Backed Securities,
see "Risk Considerations" below.
 
    To hedge against adverse changes in the prices of securities it anticipates
purchasing for its portfolio, the Fund may also write covered call and put
options against U.S. Government securities and cash held in its portfolio and
purchase options of the same or similar series to effect closing transactions.
In addition, the Fund may hedge portions of its portfolio securities against
potential changes in prevailing interest rates by purchasing put options on U.S.
Government securities and engaging in transactions involving interest rate
futures contracts and options on such contracts. See "Options and Futures
Transactions" below.
 
    While the Fund will be investing primarily in U.S. Government securities, it
may invest up to 35% of its total assets in options on U.S. Government
securities; options on futures contracts and futures contracts; repurchase
agreements; reverse repurchase agreements and dollar rolls (see "Risk
Considerations" below); money market instruments, including 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); certificates of deposit; bankers' acceptances and other
obligations of domestic banks or domestic branches of foreign banks, in each
case having total assets of at least $500 million; and obligations of foreign
governments or their respective instrumentalities or agencies. Moreover, and
notwithstanding any of the above, the Fund may invest in such instruments
without limitation, on a temporary basis, when market conditions dictate a
"defensive" investment strategy. The Fund may also borrow money for the purpose
of leveraging its investments and lend its portfolio securities, as discussed
under "Risk Considerations" below.
 
OPTIONS AND FUTURES TRANSACTIONS
 
    OPTIONS.  The Fund is permitted to enter into call and put options on U.S.
Treasury notes, bonds and bills which are listed on Exchanges and 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.
 
    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 member banks of the Federal Reserve System or
primary U.S. Government securities dealers or with affiliates of such banks or
dealers which have capital of at least $50 million or whose obligations are
guaranteed by an entity having capital of at least $50 million.
 
    COVERED CALL WRITING.  The Fund is permitted to write covered call options
on U.S. Government securities only, 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
 
                                       9
<PAGE>
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. The aggregate value of the obligations underlying
the puts determined as of the date the options are sold will not exceed 50% of
the Fund's net assets. 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 10% of its total
assets in the purchase of put and call options on U.S. Government securities.
The Fund may purchase call options only in order to close out a covered call
position. The Fund may purchase put options on U.S. Government 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.
 
    FUTURES CONTRACTS.  The Fund may also purchase and sell interest rate
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. 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 futures contracts only for
the purpose of hedging its portfolio (or anticipated portfolio) securities
against changes in prevailing interest rates. The Fund may also purchase and
write call and put options on futures contracts which are traded on an Exchange
and enter into closing transactions with respect to such options to terminate an
existing position. 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.
 
RISK CONSIDERATIONS
 
   
    The net asset value of the Fund's shares will fluctuate with changes in the
market value of its portfolio securities. The Fund's yield will also vary based
on the yield of the Fund's portfolio securities. Neither the value nor the yield
of the U.S. Government securities invested in by the Fund (or the value or yield
of the shares of the Fund) is guaranteed by the U.S. Government. Such values and
yield will fluctuate with changes in prevailing interest rates and other
factors.
    
 
    Generally, as prevailing interest rates rise, the value of the U.S.
Government securities held by the Fund, and, concomitantly, the net asset value
of the Fund's shares, will fall. Such securities with longer maturities
generally tend to produce higher yields and are subject to greater market
fluctuation as a result of changes in interest rates than debt securities with
shorter maturities. As noted above, the Fund is not limited as to the maturities
of the U.S. Government securities in which it may invest.
 
    RISKS OF MORTGAGE-BACKED SECURITIES.  Mortgage-Backed Securities have
certain different characteristics than traditional debt securities. Among the
major differences are that interest and principal payments are made more
frequently, usually monthly, and that principal may be prepaid at any time
because the underlying mortgage loans or other assets generally may be prepaid
at any time. As a result, if the Fund purchases such a security at a premium, a
prepayment rate that is faster than expected may reduce yield to maturity, while
a prepayment rate that is slower than expected may have
 
                                       10
<PAGE>
the opposite effect of increasing yield to maturity. Alternatively, if the Fund
purchases these securities at a discount, faster than expected prepayments will
increase, while slower than expected prepayments may reduce, yield to maturity.
 
    Mortgage-Backed Securities, like all fixed-income securities, generally
decrease in value as a result of increases in interest rates. In addition,
although generally the value of fixed-income securities increases during periods
of falling interest rates, Mortgage-Backed Securities may benefit less than
other fixed-income securities from declining interest rates because of the risk
of prepayments.
 
    The average life of Mortgage-Backed Securities varies with the maturities of
the underlying mortgage instruments, which may be up to thirty years but which
may include mortgage instruments with maturities of fifteen years, adjustable
rate mortgage instruments, variable rate mortgage instruments, graduated rate
mortgage instruments and/or other types of mortgage instruments. The assumed
average life of mortgages backing the majority of GNMA and FNMA certificates is
twelve years, and of FHLMC certificates is ten years. This average life is
likely to be substantially shorter than the original maturity of the mortgage
pools underlying the certificates, as a pool's duration may be shortened by
unscheduled or early payments of principal on the underlying mortgages. As
prepayment rates vary widely, it is not possible to accurately predict the
average life of a particular pool.
 
    Although the extent of prepayments on a pool of mortgage loans depends on
various factors, including the prevailing level of interest rates, general
economic conditions, the location and age of the mortgage and other social and
demographic conditions, as a general rule prepayments on fixed rate mortgage
loans will increase during a period of falling interest rates and decrease
during a period of rising interest rates. If the Fund has purchased securities
backed by pools containing mortgages whose yields exceed the prevailing interest
rate, any premium paid for such securities may be lost. As a result, the net
asset value of shares of the Fund and the Fund's ability to achieve its
investment objective may be adversely affected by mortgage prepayments. Amounts
available for reinvestment by the Fund are likely to be greater during a period
of declining interest rates and, as a result, likely to be reinvested at lower
interest rates than during a period of rising interest rates.
 
    There are certain risks associated specifically with CMOs. CMOs issued by
private entities are not U.S. Government securities and are not guaranteed by
any government agency, although the securities underlying a CMO may be subject
to a guarantee. Therefore, if the collateral securing the CMO, as well as any
third party credit support or guarantees, is insufficient to make payment, the
holder could sustain a loss. However, the Fund will invest in CMOs issued by
private entities only if the CMOs are rated Aaa by Moody's or AAA by S&P, or, if
unrated, such CMOs are determined to be of comparable quality to the permitted
rated investments. Also, a number of different factors, including the extent of
prepayment of principal of the Mortgage Assets, affect the availability of cash
for principal payments by the CMO issuer on any payment date and, accordingly,
affect the timing of principal payments on each CMO class.
 
    RISKS OF OPTIONS AND FUTURES TRANSACTIONS. The Fund may close out its
position as writer of an option only if a liquid secondary market exists for
options 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 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.
 
    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."
 
                                       11
<PAGE>
    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 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 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.
 
   
    REPURCHASE AGREEMENTS.  The Fund may enter into repurchase agreements, which
may be viewed as a type of secured lending by the Fund, and which typically
involve the acquisition by the Fund of debt securities from a selling financial
institution such as a bank, savings and loan association or broker-dealer. The
agreement provides that the Fund will sell back to the institution, and that the
institution will repurchase, the underlying security at a specified price and at
a fixed time in the future, usually not more than seven days from the date of
purchase. While repurchase agreements involve certain risks not associated with
direct investments in debt securities, including the risks of default or
bankruptcy of the selling financial institution, the Fund follows procedures
designed to minimize those risks. These procedures include effecting repurchase
transactions only with large, well-capitalized and well-established financial
institutions whose financial condition will be continually monitored by the
Investment Manager subject to procedures established by the Board of Trustees of
the Fund. 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.
    
 
    LEVERAGING.  The Fund may borrow money, but only from a bank and in an
amount up to 25% of the Fund's total assets taken at the lower of market value
or cost, not including the amount borrowed. When the Fund borrows it will be
because it seeks additional income by leveraging its investments through
purchasing securities with the borrowed funds. The Fund will be required to
maintain an asset coverage (including the proceeds of borrowings) of at least
300% of such borrowings in accordance with the provisions of the Investment
Company Act of 1940, as amended (the "Act"). The investment policy provides that
the Fund may not purchase or sell a security on margin. Borrowings for
leveraging will be subject to current margin requirements of the Federal Reserve
Board and where necessary the Fund may use any or all of its securities as
collateral for such borrowings. Any investment gains made with the additional
monies in excess of interest paid will cause the net asset value of the Fund's
shares to rise to a greater extent than would otherwise be the case. Conversely,
if the investment performance of the additional monies fails to cover their cost
to the Fund, net asset value will decrease to a greater extent than would
otherwise be the case. This is the speculative factor involved in leverage. If,
due to market fluctuations or other reasons, the value of the Fund's assets
(including the proceeds of borrowings) becomes at any time less than three times
the amount of any outstanding bank debt, the Fund, within three
busi-
 
                                       12
<PAGE>
ness days, will reduce its bank debt to the extent necessary to meet the
required 300% asset coverage. In doing this, the Fund may have to sell a portion
of its investments at a time when it may be disadvantageous to do so.
 
    ZERO COUPON SECURITIES.  A portion of the fixed-income securities purchased
by the Fund may be zero coupon securities. Such securities are purchased at a
discount from their face amount, giving the purchaser the right to receive their
full value at maturity. The interest earned on such securities is, implicitly,
automatically compounded and paid out at maturity. While such compounding at a
constant rate eliminates the risk of receiving lower yields upon reinvestment of
interest if prevailing interest rates decline, the owner of a zero coupon
security will be unable to participate in higher yields upon reinvestment of
interest received on interest-paying securities if prevailing interest rates
rise.
 
    A zero coupon security pays no interest to its holder during its life.
Therefore, to the extent the Fund invests in zero coupon securities, it will not
receive current cash available for distribution to shareholders. In addition,
zero coupon securities are subject to substantially greater price fluctuations
during periods of changing prevailing interest rates than are comparable
securities which pay interest on a current basis. Current federal tax law
requires that a holder (such as the Fund) of a zero coupon security accrue a
portion of the discount at which the security was purchased as income each year
even though the Fund receives no interest payments in cash on the security
during the year.
 
    WHEN-ISSUED AND DELAYED DELIVERY SECURITIES AND FIRM COMMITMENTS.  From time
to time, in the ordinary course of business, the Fund may purchase U.S.
Government securities on a when-issued or delayed delivery basis or may purchase
or sell U.S. Government securities on a firm commitment basis. When such
transactions are negotiated, the price is fixed at the time of the commitment,
but delivery and payment can take place a month or more after the date of the
commitment. There is no overall limit on the percentage of the Fund's assets
which may be committed to the purchase of securities on a when-issued, delayed
delivery or forward commitment basis. An increase in the percentage of the
Fund's assets committed to the purchase of securities on a when-issued, delayed
delivery or forward commitment basis may increase the volatility of the Fund's
net asset value.
 
    REVERSE REPURCHASE AGREEMENTS AND DOLLAR ROLLS.  The Fund may also use
reverse repurchase agreements and dollar rolls as part of its investment
strategy. Reverse repurchase agreements involve sales by the Fund of portfolio
assets concurrently with an agreement by the Fund to repurchase the same assets
at a later date at a fixed price. The Fund may enter into dollar rolls in which
the Fund sells securities for delivery in the current month and simultaneously
contracts to repurchase substantially similar (same type and coupon) securities
on a specified future date. Reverse repurchase agreements and dollar rolls
involve the risk that the market value of the securities the Fund is obligated
to repurchase under the agreement may decline below the repurchase price. In the
event the buyer of securities under a reverse repurchase agreement or dollar
roll files for bankruptcy or becomes insolvent, the Fund's use of the proceeds
of the agreement may be restricted pending a determination by the other party,
or its trustee or receiver, whether to enforce the Fund's obligation to
repurchase the securities.
 
    Reverse repurchase agreements and dollar rolls are speculative techniques
involving leverage, and are considered borrowings by the Fund.
 
    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,
 
                                       13
<PAGE>
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.
 
    For additional risk disclosure, please refer to the discussion of specific
investments under the "Investment Objective and Policies" section of the
Prospectus and the "Investment Practices and Policies" section of the Statement
of Additional Information.
 
PORTFOLIO MANAGEMENT
 
   
    The Fund's portfolio is actively managed by its Investment Manager with a
view to achieving the Fund's investment 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"), a broker-dealer affiliate of InterCapital, the views of
Trustees of the Fund and others regarding economic developments and interest
rate trends, and the Investment Manager's own analysis of factors it deems
relevant. The Fund is managed within InterCapital's Taxable Fixed-Income Group,
which manages twenty-five funds and fund portfolios, with approximately $13
billion in assets at November 30, 1996. Rajesh K. Gupta, Senior Vice President
of InterCapital and a member of InterCapital's Taxable Fixed-Income Group, has
been the primary portfolio manager of the Fund since June, 1987 and has been
managing portfolios comprised of government securities at InterCapital for over
five years.
    
 
    Brokerage commissions are not normally charged on the purchase or sale of
U.S. Government obligations, but such transactions may involve costs in the form
of spreads between bid and asked prices. Orders for transactions in other
portfolio securities and commodities are placed for the Fund with a number of
brokers and dealers, including DWR. 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. It is not anticipated that
the portfolio trading engaged in by the Fund will result in its portfolio
turnover rate exceeding 100%.
 
    Except as specified, the investment policies noted above are not fundamental
policies and may be changed without shareholder approval.
 
INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------
 
    The investment restrictions listed below are among the restrictions that
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.
 
    The Fund may not:
 
   1. Invest more than 5% of the value of its total assets in the securities of
any one issuer (other than obligations issued, or guaranteed by, the United
States Government, its agencies or instrumentalities).
 
   2. Purchase more than 10% of all outstanding voting securities or any class
of securities of any one issuer.
 
   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. The Investment Manager disagrees with this position.
Nevertheless, the Fund has agreed to treat OTC
 
                                       14
<PAGE>
options and the covering assets thereon as illiquid securities for purposes of
this investment restriction.
 
   4. Invest more than 5% of the value of its total assets in securities of
issuers having a record, together with predecessors, of less than three years of
continuous operation. This restriction shall not apply to any obligation of the
United States Government, its agencies or instrumentalities.
 
   5. Purchase or sell commodities or commodities contracts except that the Fund
may purchase or write interest rate futures contracts and related options
thereon.
 
   6. 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.)
 
   7. 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.
 
   8. Borrow money, except from banks for investment purposes or as a temporary
measure for extraordinary or emergency purposes in an amount up to 25% of the
Fund's total assets, within the limits set forth in the Act or enter into
reverse repurchase agreements in an amount exceeding 10% of the Fund's total
assets other than for purposes of meeting redemptions.
 
    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.
 
PURCHASE OF FUND SHARES
- --------------------------------------------------------------------------------
 
    The Fund offers 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 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 minimum initial purchase is $1,000. Subsequent purchases of $100 or more
may be made by sending a check, payable to Dean Witter Federal Securities Trust,
directly to Dean Witter Trust Company (the "Transfer Agent") at P.O. Box 1040,
Jersey City, NJ 07303 or by contacting an account executive of DWR or other
Selected Broker-Dealer. 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 all accounts under such Plans to at least $1,000.
Certificates for shares purchased will not be issued unless a request is made by
the shareholder in writing to the Transfer Agent. The offering price will be the
net asset value per share next determined following receipt of an order (see
"Determination of Net Asset Value" below).
    
 
    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
 
                                       15
<PAGE>
day (settlement date) after the order is placed with the Distributor. Shares of
the Fund purchased through the Distributor are entitled to dividends beginning
on the next business day following settlement date. 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. Shares
purchased through the Transfer Agent are entitled to dividends beginning on the
next business day following receipt of an order. As noted above, orders placed
directly with the Transfer Agent must be accompanied by payment. Investors will
be entitled to receive capital gains distributions if their order is received by
the close of business on the day prior to the record date for such
distributions. While no sales charge is imposed at the time shares are
purchased, a contingent deferred sales charge may be imposed at the time of
redemption (see "Redemptions and Repurchases"). Sales personnel are compensated
for selling shares of the Fund at the time of their sale by the Distributor
and/or 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.
 
PLAN OF DISTRIBUTION
 
    The Fund has adopted a Plan of Distribution pursuant to Rule 12b-1 under the
Act (the "Plan"), under which the Fund pays the Distributor a fee, which is
accrued daily and paid monthly, at an annual rate of 0.85% of the lesser of: (a)
the average daily aggregate gross sales of the Fund's shares since the inception
of the Fund (not including reinvestments of dividends or distributions), less
the average daily aggregate net asset value of the Fund's shares redeemed since
the Fund's inception upon which a contingent deferred sales charge has been
imposed or waived, or (b) the Fund's average daily net assets. This fee is
treated by the Fund as an expense in the year it is accrued. A portion of the
fee payable pursuant to the Plan, equal to 0.20% of the Fund's average daily net
assets, is characterized as a service fee within the meaning of NASD guidelines.
The service fee is a payment made for personal service and/or the maintenance of
shareholder accounts.
 
    Amounts paid under the Plan are 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, including the payment of commissions for
sales of the Fund's shares and incentive compensation to and expenses of DWR
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 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 distribution expenses.
 
   
    For the fiscal year ended October 31, 1996, the Fund accrued payments under
the Plan amounting to $6,554,450, which amount is equal to 0.85% of the Fund's
average daily net assets for the fiscal year. The payments accrued under the
Plan were calculated pursuant to clause (b) of the compensation formula under
the Plan.
    
 
    At any given time, the expenses of distributing 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 contingent deferred sales charges paid by investors
upon the redemption of shares (see "Redemptions and Repurchases--Contingent
Deferred Sales Charge"). For example, if $1 million in expenses in distributing
shares of the Fund had been incurred and $750,000 had been received as described
in (i) and (ii) above, the excess expense would amount to $250,000. The
Distributor has advised the Fund that such excess
 
                                       16
<PAGE>
   
amount, including the carrying charge described above, totalled $27,489,031 at
October 31, 1996, which was equal to 3.82% of the Fund's net assets on such
date. Because there is no requirement under the Plan that the Distributor be
reimbursed for all distribution expenses or any requirement that the Plan be
continued from year to year, this excess amount does not constitute a liability
of the Fund. Although there is no legal obligation for the Fund to pay expenses
incurred in excess of payments made to the Distributor under the Plan and the
proceeds of contingent deferred sales charges paid by investors upon redemption
of shares, if for any reason the Plan is terminated the Trustees will consider
at that time the manner in which to treat such expenses. Any cumulative expenses
incurred, but not yet recovered through distribution fees or contingent deferred
sales charges, may or may not be recovered through future distribution fees or
contingent deferred sales charges.
    
 
DETERMINATION OF NET ASSET VALUE
 
    The net asset value per share 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 by taking the value of all assets of the Fund, subtracting all
its liabilities, dividing by the number of shares outstanding and adjusting to
the nearest cent. 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) all portfolio
securities for which over-the-counter market quotations are readily available
are valued at the latest bid price prior to the time of valuation, and (2) 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 securities
for which market quotations are not readily available may also 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 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. The value of other assets will be determined in good faith under
procedures established by and under the supervision of the Trustees.
 
   
    Certain of the Fund's portfolio securities may
be valued by an outside pricing service approved
by the Fund's Trustees. The pricing service may utilize a matrix system
incorporating security quality, maturity and coupon as the evaluation model
parameters, and/or research evaluations by its staff, including review of
broker-dealer market price quotations, in determining what it believes is the
fair valuation of the portfolio securities valued by such pricing service.
    
 
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 Fund (or, if specified by the shareholder, any other open-end
investment company for which InterCapital serves as investment manager
(collectively, with the Fund, the "Dean Witter Funds")), unless the shareholder
requests that they be paid in cash. Shares so acquired are not subject to the
imposition of a contingent deferred sales charge upon their redemption (see
"Redemptions and Repurchases"). Such dividends and distributions will
 
                                       17
<PAGE>
be paid, at the net asset value per share, in shares of the Fund (or in cash if
the shareholder so requests) on the monthly payment date, which will be no later
than the last business day of the month for which the dividend or distribution
is payable. Processing of dividend checks begins immediately following the
monthly payment date. Shareholders who have requested to receive dividends in
cash will normally receive their monthly dividend check during the first ten
days of the following month.
 
    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 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 not subject to the imposition of a contingent
deferred sales charge upon their redemption (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, on a semi-monthly,
monthly or quarterly basis, to the Transfer Agent for investment in shares of
the Fund (see "Purchase of Fund Shares" and "Redemptions and
Repurchases--Involuntary Redemption").
 
    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
contingent deferred sales charge will be imposed on shares redeemed under the
Withdrawal Plan (see "Redemptions and Repurchases--Contingent Deferred Sales
Charge"). 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 contingent deferred sales charge) to the shareholder will
be the designated monthly or quarterly amount.
 
    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 through the
Distributor for use by corporations, the self-employed, Individual Retirement
Accounts and Custodial Accounts under Section 403(b)(7) of the Internal Revenue
Code. Adoption of such plans should be on advice of legal counsel or tax
adviser.
 
    For further information regarding plan administration, custodial fees and
other details, investors should contact their account executive or the Fund.
 
    EXCHANGE PRIVILEGE.  The Fund makes available to its shareholders an
"Exchange Privilege" allowing the exchange of shares of the Fund for shares of
other Dean Witter Funds sold with a contingent deferred sales charge ("CDSC
funds"), and for shares of Dean Witter Short-Term U.S. Treasury Trust, Dean
Witter Limited Term Municipal Trust, Dean Witter Short-Term Bond Fund, Dean
Witter Balanced Growth Fund, Dean Witter Balanced Income Fund, Dean Witter
Intermediate Term U.S. Treasury Trust and five Dean Witter Funds which are money
market funds (the foregoing eleven non-CDSC funds are hereinafter referred to as
the "Exchange Funds"). Exchanges may be made after the shares of the Fund
acquired by purchase (not by exchange or dividend reinvestment) have been held
for thirty days. There is no waiting period for exchanges of shares acquired by
exchange or dividend reinvestment.
 
    An exchange to another 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
 
                                       18
<PAGE>
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 CDSC funds can be effected on the same basis. No contingent
deferred sales charge ("CDSC") is imposed at the time of any exchange, although
any applicable CDSC will be imposed upon ultimate redemption. Shares of the Fund
acquired in exchange for shares of another CDSC fund having a different CDSC
schedule than that of this Fund will be subject to the CDSC schedule of this
Fund, even if such shares are subsequently re-exchanged for shares of the CDSC
fund originally purchased. 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 (for the purpose of
determining the rate of the CDSC) is frozen. If those shares are subsequently
reexchanged for 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 CDSC fund are reacquired. Thus, the CDSC is based upon the time (calculated
as described above) the shareholder was invested in a CDSC fund (see
"Redemptions and Repurchases--Contingent Deferred Sales Charge"). 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 incurred on or after that date which are
attributable to those shares. (Exchange Fund 12b-1 distribution fees are
described in the prospectuses for those funds.)
 
    In addition, shares of the Fund may be acquired in exchange for shares of
Dean Witter Funds sold with a front-end sales charge ("front-end sales charge
funds"), but shares of the Fund, however acquired, may not be exchanged for
shares of front-end sales charge funds. Shares of a CDSC fund acquired in
exchange for shares of a front-end sales charge fund (or in exchange for shares
of other Dean Witter Funds for which shares of a front-end sales charge fund
have been exchanged) are not subject to any CDSC upon their redemption.
 
    Purchases and exchanges should be made for investment purposes only. A
pattern of frequent exchanges may be deemed by the Investment Manager to be
abusive and contrary to the best interests of the Fund's other shareholders and,
at the Investment Manager's discretion, may be limited by the Fund's refusal to
accept additional purchases and/ or exchanges from the investor. Although the
Fund does not have any specific definition of what constitutes a pattern of
frequent exchanges, and will consider all relevant factors in determining
whether a particular situation is abusive and contrary to the best interests of
the Fund and its other shareholders, investors should be aware that the Fund and
each of the other Dean Witter Funds may in their discretion limit or otherwise
restrict the number of times this Exchange Privilege may be exercised by any
investor. Any such restriction will be made by the Fund on a prospective basis
only, upon notice to the shareholder not later than ten days following such
shareholder's most recent exchange. Also, the Exchange Privilege may be
terminated or revised at any time by the Fund and/or any of such Dean Witter
Funds for which shares of the Fund have been exchanged, upon such notice as may
be required by applicable regulatory agencies. Shareholders maintaining margin
accounts with DWR or another Selected Broker-Dealer are referred to their
account executive regarding restrictions on exchange of shares of the Fund
pledged in the margin account.
 
    The current prospectus for each fund describes its investment objective(s)
and policies, and shareholders should obtain a copy and examine it carefully
before investing. Exchanges are subject to the minimum investment requirement
and any other conditions imposed by each fund. An exchange will be treated for
federal income tax purposes the same as a repurchase or redemption of shares, on
which
 
                                       19
<PAGE>
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 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 the Fund can be redeemed for cash at any time at the
net asset value per share next determined; however, such redemption proceeds may
be reduced by the amount of any applicable contingent deferred sales charges
(see below). 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(s), the shares may be redeemed by surrendering the certificate(s)
with a written request for redemption, along with any additional information
required by the Transfer Agent.
 
                                       20
<PAGE>
    CONTINGENT DEFERRED SALES CHARGE.  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 charge upon redemption.
Shares redeemed sooner than six years after purchase may, however, be subject to
a charge upon redemption. This charge is called a "contingent deferred sales
charge" ("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 table below:
 
<TABLE>

             PURCHASE                   ON A PERCENTAGE OF
           PAYMENT MADE                  AMOUNT REDEEMED
- -----------------------------------  ------------------------
<S>                                  <C>
First..............................              5.0%
Second.............................              4.0%
Third..............................              3.0%
Fourth.............................              2.0%
Fifth..............................              2.0%
Sixth..............................              1.0%
Seventh and thereafter.............            None
</TABLE>
 
    A CDSC will not be imposed on: (i) any amount which represents an increase
in value of shares purchased within the six years preceding the redemption; (ii)
the current net asset value of shares purchased more than six 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 Dean Witter Funds sold with a front-end sales charge 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-
 
                                       21
<PAGE>
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
corporate or self-employed retirement plan qualified under Section 401(k) 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 Dean Witter Trust Company or
Dean Witter Trust FSB, each of which is an affiliate of the Investment Manager,
serves as Trustee ("Eligible 401(k) Plan"), provided that either:  (A) the plan
continues to be an Eligible 401(k) 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.
 
    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 upon repurchase by the Fund,
the Distributor, DWR and other Selected Broker-Dealers. 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 receipt of the check by the Transfer Agent).
Shareholders maintaining margin accounts with DWR or another Selected Broker-
Dealer are referred to their account executive regarding restrictions on
redemption of shares of the Fund pledged in the margin account.
 
    REINSTATEMENT PRIVILEGE.  A shareholder who has had his or her shares
redeemed or repurchased and has not previously exercised this reinstatement
privilege may, within thirty 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 at the 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 Internal Revenue Code) whose shares due to
 
                                       22
<PAGE>
   
redemptions by the shareholder have a value of less than $100 or such lesser
amount as may be fixed by the Trustees or, in the case of an account opened
through EasyInvest-SM-, if after twelve months the shareholder has invested less
than $1,000 in the account. However, before the Fund redeems such shares and
sends the proceeds to the shareholder, it will notify the shareholder that the
value of the shares is less than the applicable amount and allow him or her
sixty days to make an additional investment in an amount which will increase the
value of his of her account to at least the applicable amount before the
redemption is processed. No CDSC will be imposed on any involuntary redemption.
    
 
DIVIDENDS, DISTRIBUTIONS AND TAXES
- --------------------------------------------------------------------------------
 
    DIVIDENDS AND DISTRIBUTIONS.  The Fund declares dividends from net
investment income on each day the New York Stock Exchange is open for business
to shareholders of record as of the close of business the preceding business
day. Such dividends are paid monthly. The Fund intends to distribute all of the
Fund's net investment income on an annual basis.
 
    The Fund may pay quarterly dividends of realized net short-term capital
gains, if any. Such dividends may include a portion of the premiums
received by the Fund from expired call and put options written by the Fund on
U.S. Government securities, and of the net gains realized on closing purchase
transactions with respect to such options. The Fund may elect to retain a
portion of any net short-term capital gains for reinvestment. Net realized
long-term capital gains, if any, will be distributed at least once per year,
although the Investment Manager reserves the right to retain a portion of such
gains for reinvestment.
 
   
    As of October 31, 1996, the Fund had a net capital loss carryover of
approximately $58,206,000. To the extent of such carryover, the Fund could
retain gains realized in future years without either the Fund or its
shareholders being required to pay a tax on such gains. However, the Fund may
distribute to shareholders realized gains. Such distributions could,
notwithstanding the loss carryover, be taxable to shareholders to the extent of
the Fund's realized gains. Also, the Fund may at times make payments from
sources other than income or net capital gains. Payments from such sources will,
in effect, represent a return of a portion of each shareholder's investment.
All, or a portion, of such payments will not be taxable to shareholders.
    
 
    All dividends and capital gains distributions will be paid in additional
Fund shares (without sales charge) and automatically credited to the
shareholder's account without issuance of a share certificate unless the
shareholder requests in writing that all dividends be paid in cash. (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 on such income and capital gains.
 
    Gains or losses on the Fund's transactions in listed options on securities,
futures and options on futures may be treated as 60% long-term and 40%
short-term. When the Fund engages in options and futures transactions, various
tax regulations applicable to the Fund may have the effect of causing the Fund
to recognize a gain or loss for tax purposes before that gain or loss is
realized, or to defer recognition of a realized loss for tax purposes.
Recognition, for tax purposes, of an unrealized loss may result in a lesser
amount of the Fund's realized net short-term gains being available for quarterly
distribution.
 
    As a regulated investment company, the Fund is subject to the requirement
that less than 30% of its gross income be derived 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
 
                                       23
<PAGE>
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.
 
    Shareholders who are required to pay taxes on their income will normally
have to pay federal income taxes, and any applicable state and/or local income
taxes, on the dividends and distributions they receive from the Fund. Such
dividends and distributions, to the extent that they are derived from net
investment income and net short-term capital gains, are taxable to the
shareholder as ordinary dividend income regardless of whether the shareholder
receives such distributions in additional shares or in cash.
 
    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.
 
    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, distributions and the proceeds of redemptions and repurchases,
shareholders' taxpayer identification numbers must be furnished and certified as
to their accuracy.
 
    The foregoing discussion relates solely to the federal income tax
consequences of an investment in the Fund. Distributions may also be subject to
state and local taxes; therefore, each shareholder is advised to consult his or
her own tax adviser.
 
PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
 
    From time to time the Fund may quote its "yield" and/or its "total return"
in advertisements and sales literature. Both the yield and the total return of
the Fund are based on historical earnings and are not intended to indicate
future performance. The yield of the Fund is computed by dividing the Fund's net
investment income over a 30-day period by an average value (using the average
number of shares entitled to receive dividends and the net asset value per share
at the end of the period), all in accordance with applicable regulatory
requirements. Such amount is compounded for six months and then annualized for a
twelve-month period to derive the Fund's yield.
 
   
    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 the Fund of $1,000 over periods of one, five and ten
years, or 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 Fund and all
sales charges 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 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 the contingent deferred 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 shares of the Fund.
The Fund from time to time may also advertise its performance relative to
certain performance rankings and indexes compiled by independent organizations
(such as Lipper Analytical Services, Inc. and Salomon Brothers Treasury Index,
Shearson Lehman Government Bond Index, Merrill Lynch Mortgage Master Index and
Donahue's Money Market Index).

ADDITIONAL INFORMATION
- --------------------------------------------------------------------------------
 
    VOTING RIGHTS.  All shares of beneficial interest of the Fund are of $0.01
par value and are equal as to earnings, assets and voting privileges.
 
    The Fund is not required to hold Annual Meetings of Shareholders and in
ordinary circumstances the Fund does not intend to hold such meetings. The
Trustees may call Special Meetings of Shareholders for action by shareholder
vote as may be required by the Act or the Declaration of Trust. Under certain
circumstances the Trustees may be removed by action of the Trustees or by the
shareholders.
 
    Under Massachusetts law, shareholders of a business trust may, under certain
circumstances, be held personally liable as partners for the obligations of the
Fund. However, the Declaration of Trust contains an express disclaimer of
shareholder liability for acts or obligations of the Fund, requires that Fund
obligations include such disclaimer, and provides for indemnification and
reimbursement of expenses out of the Fund's property for any shareholder held
personally liable for the obligations of the Fund. Thus, the risk of a
shareholder incurring financial loss on account of shareholder liability is
limited to circumstances in which the Fund itself would be unable to meet its
obligations. Given the above limitations on shareholder personal liability, and
the nature of the Fund's assets and operations, the possibility of the Fund
being unable to meet its obligations is remote and, in the opinion of
Massachusetts counsel to the Fund, the risk to Fund shareholders of personal
liability is remote.
 
    CODE OF ETHICS.  Directors, officers and employees of InterCapital, Dean
Witter Services Company Inc. and the Distributor are subject to a strict Code of
Ethics adopted by those companies. The Code of Ethics is intended to ensure that
the interests of shareholders and other clients are placed ahead of any personal
interest, that no undue personal benefit is obtained from a person's employment
activities and that actual and potential conflicts of interest are avoided. To
achieve these goals and comply with regulatory requirements, the Code of Ethics
requires, among other things, that personal securities transactions by employees
of the companies be subject to an advance clearance process to monitor that no
Dean Witter Fund is engaged at the same time in a purchase or sale of the same
security. The Code of Ethics bans the purchase of securities in an initial
public offering, and also prohibits engaging in futures and options transactions
and profiting on short-term trading (that is, a purchase within sixty days of a
sale or a sale within sixty days of a purchase) of a security. In addition,
investment personnel may not purchase or sell a security for their personal
account within thirty days before or after any transaction in any Dean Witter
Fund managed by them. Any violations of the Code of Ethics are subject to
sanctions, including reprimand, demotion or suspension or 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.
 
    SHAREHOLDER INQUIRES.  All inquiries regarding the Fund should be directed

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
November  20,  1986. The  Fund's name  was changed  from Dean  Witter Government
Securities Plus to Dean Witter Federal  Securities Trust by the Trustees of  the
Fund on August 17, 1992.
 
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 Dean Witter, Discover &  Co. ("DWDC"), a Delaware corporation.  In
an  internal  reorganization which  took  place in  January,  1993, InterCapital
assumed  the  investment  advisory,  administrative  and  management  activities
previously  performed by the InterCapital Division  of Dean Witter Reynolds Inc.
("DWR"), a broker-dealer affiliate of InterCapital. (As hereinafter used in this
Statement of Additional  Information, the terms  "InterCapital" and  "Investment
Manager"   refer  to   DWR's  InterCapital   Division  prior   to  the  internal
reorganization  and  Dean  Witter  InterCapital  Inc.  thereafter.)  The   daily
management  of  the  Fund  and  research relating  to  the  Fund's  portfolio is
conducted by  or  under  the direction  of  officers  of the  Fund  and  of  the
Investment  Manager,  subject  to  review  by  the  Fund's  Board  of  Trustees.
Information as to  these Trustees and  officers is contained  under the  caption
"Trustees and Officers."

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

Opportunities Trust, TCW/DW Term Trust 2000,  TCW/DW Term Trust 2002 and  TCW/DW
Term  Trust  2003  (the  "TCW/DW  Funds").  InterCapital  also  serves  as:  (i)
sub-adviser to  Templeton Global  Opportunities  Trust, an  open-end  investment
company;  (ii)  administrator  of The  BlackRock  Strategic Term  Trust  Inc., a
closed-end  investment  company;  and  (iii)  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 and policies.
 
    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,  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 that  date.  The
foregoing internal reorganizations did not result in any change in the nature or
scope  of the administrative services  being provided to the  Fund or any of the
fees being paid by the Fund for  the overall services being performed under  the
terms of the existing Agreement.
 
    Expenses not expressly assumed by the Investment Manager under the Agreement
or  by  the Distributor  of  the Fund's  shares,  Dean Witter  Distributors Inc.
("Distributors" or the "Distributor") (see  "The Distributor"), will be paid  by
the  Fund.  The expenses  borne by  the Fund  include, but  are not  limited to:
expenses  of  the  Plan  of  Distribution  pursuant  to  Rule  12b-1  (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; fees  and expenses  of legal  counsel,
including counsel to the Trustees who
 
                                       4
<PAGE>
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.
 
   
    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: 0.55% of the portion of
the daily net assets of the Fund not exceeding $1 billion; 0.525% of the portion
of the  Fund's daily  net assets  exceeding $1  billion but  not exceeding  $1.5
billion;  0.50% of  the portion  of the Fund's  daily net  assets exceeding $1.5
billion but not exceeding $2 billion; 0.475% of the portion of the Fund's  daily
net  assets exceeding $2  billion but not  exceeding $2.5 billion;  0.45% of the
portion of the Fund's daily net assets exceeding $2.5 billion but not  exceeding
$5  billion; 0.425% of the  portion of the Fund's  daily net assets exceeding $5
billion but not exceeding $7.5 billion; 0.40% of the portion of the Fund's daily
net assets exceeding $7.5 billion but  not exceeding $10 billion; 0.375% of  the
portion  of the Fund's daily net assets  exceeding $10 billion but not exceeding
$12.5 billion; and 0.35% of the portion of the Fund's daily net assets exceeding
$12.5 billion.  Total compensation  accrued to  the Investment  Manager for  the
fiscal  years  ended October  31, 1994,  1995 and  1996 amounted  to $5,387,156,
$4,542,697 and $4,241,115, 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 Trustees on October 30, 1992 and
by the shareholders of the Fund at a Special Meeting of Shareholders on  January
12,  1993.  The  Agreement  is substantially  identical  to  a  prior investment
agreement which was initially approved by the Trustees on December 15, 1986,  by
DWR  as the then sole shareholder on January 13, 1987 and by the shareholders at
a Meeting of  Shareholders on May  31, 1988,  as such prior  agreement had  been
amended  by the Independent Trustees at their  meeting held on April 28, 1988 to
lower the management fee  payable to the Investment  Manager to the current  fee
payable.  The Agreement took effect on June 30, 1993 upon the spin-off by Sears,
Roebuck and Co. of its remaining shares of DWDC. The Agreement may be terminated
at any time, without penalty, on thirty days' notice by the Board of Trustees of
the Fund, by the holders of a majority, as defined in the Investment Company Act
of 1940 (the "Act"), of the outstanding shares of the Fund, or by the Investment
Manager. The  Agreement  will  automatically  terminate  in  the  event  of  its
assignment (as defined in the Act).
 
   
    Under  its terms, the Agreement  had an initial term  ending April 30, 1994,
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. At their meeting
held  on April  17, 1996,  the Fund's  Board of  Trustees, including  all of the
Independent Trustees, approved  continuation of  the Agreement  until April  30,
1997.
    
 
   
    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 consists of eight (8) 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 82 Dean Witter Funds, comprised  of
122  portfolios. As of  November 30, 1996,  the Dean Witter  Funds had total net
assets of approximately $82.2 billion and more than five million shareholders.
    
 
   
    Six Trustees  (75% 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, DWDC. These
are the "disinterested" or "independent"  Trustees. The other two Trustees  (the
"management  Trustees")  are  affiliated  with  InterCapital.  Four  of  the six
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, 1995,
the three Committees held a combined  total of fifteen meetings. The  Committees
hold  some  meetings at  InterCapital's offices  and some  outside InterCapital.
Management Trustees or  officers do not  attend these meetings  unless they  are
invited for purposes of furnishing information or making a report.
 
    The  Committee of the  Independent Trustees is  charged with recommending to
the full Board  approval of management,  advisory and administration  contracts,
Rule  12b-1  plans  and distribution  and  underwriting  agreements; continually
reviewing Fund performance;  checking on  the pricing  of portfolio  securities,
brokerage  commissions, transfer agent costs  and performance, and trading among
Funds in the  same complex; and  approving fidelity bond  and related  insurance
coverage and allocations, as well as other matters that arise from time to time.
The Independent Trustees are required to select and nominate individuals to fill
any  Independent Trustee vacancy on the Board of  any Fund that has a Rule 12b-1
plan of distribution. Most of the Dean Witter Funds have such a plan.
 
                                       8
<PAGE>
    The Audit  Committee is  charged with  recommending to  the full  Board  the
engagement  or  discharge  of  the  Fund's  independent  accountants;  directing
investigations into matters  within the  scope of  the independent  accountants'
duties,  including the power  to retain outside  specialists; reviewing with the
independent accountants the audit plan  and results of the auditing  engagement;
approving  professional  services provided  by  the independent  accountants and
other accounting firms prior to the performance of such services; reviewing  the
independence  of the independent accountants; considering the range of audit and
non-audit fees;  reviewing  the  adequacy  of  the  Fund's  system  of  internal
controls;  and preparing  and submitting Committee  meeting minutes  to the full
Board.
 
    Finally, the  Board of  each  Fund has  formed  a Derivatives  Committee  to
establish  parameters for and oversee the activities of the Fund with respect to
derivative investments, if any, made by the Fund.
 
   
DUTIES OF CHAIRMAN OF COMMITTEE OF THE INDEPENDENT TRUSTEES AND AUDIT COMMITTEE
    
 
   
    The Chairman of  the Committee  of the  Independent Trustees  and the  Audit
Committee  maintains an  office at  the Funds' headquarters  in New  York. He is
responsible for keeping abreast of regulatory and industry developments and  the
Funds'  operations and management. He  screens and/or prepares written materials
and identifies  critical  issues  for  the  Independent  Trustees  to  consider,
develops  agendas  for Committee  meetings, determines  the  type and  amount of
information that the Committees will need to form a judgment on various  issues,
and  arranges to have  that information furnished to  Committee members. He also
arranges for  the services  of independent  experts and  consults with  them  in
advance  of meetings  to help  refine reports and  to focus  on critical issues.
Members of the Committees believe that the person who serves as Chairman of both
Committees and guides their efforts is  pivotal to the effective functioning  of
the Committees.
    
 
    The  Chairman of the  Committees also maintains  continuous contact with the
Funds' management, with independent counsel to the Independent Trustees and with
the Funds' independent auditors.  He arranges for a  series of special  meetings
involving  the  annual  review  of  investment  advisory,  management  and other
operating contracts of  the Funds  and, on  behalf of  the Committees,  conducts
negotiations with the Investment Manager and other service providers. In effect,
the  Chairman of the Committees  serves as a combination  of chief executive and
support staff of the Independent Trustees.
 
   
    The Chairman of  the Committee  of the  Independent Trustees  and the  Audit
Committee  is  not  employed by  any  other  organization and  devotes  his time
primarily to  the services  he performs  as Committee  Chairman and  Independent
Trustee  of the Dean  Witter Funds and  as an Independent  Trustee of the TCW/DW
Funds 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  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
    
 
                                       9

Committee of the Independent Trustees an  additional annual fee of $1,200).  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.

Independent Trustees by the Fund for the fiscal year ended October 31, 1996.

(1)  For the 79  Dean Witter Funds in  operation at December  31, 1995. As noted
    above, on July 1, 1996,  Mr. Haire became Chairman  of the Committee of  the
    Independent Trustees and the Audit Committee of the TCW/DW Funds in addition
    to continuing to serve in such positions for the Dean Witter Funds.
    
 
   
    As  of the date of this Statement  of Additional Information, 57 of the Dean
Witter Funds, including the Fund, have adopted a retirement program under  which
an  Independent Trustee who  retires after serving  for at least  five years (or
such lesser period as may be determined by the Board) as an Independent Director
or Trustee of any Dean Witter Fund that has adopted the retirement program (each
such Fund referred to as an "Adopting Fund" and each such Trustee referred to as
an "Eligible  Trustee") is  entitled to  retirement payments  upon reaching  the
eligible  retirement age (normally, after attaining age 72). Annual payments are
based upon length of service. Currently, upon retirement, each Eligible  Trustee
is  entitled to  receive from  the Adopting  Fund, commencing  as of  his or her
retirement date and continuing 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
    
 
                                       10
<PAGE>
   
Board.(2)  "Eligible Compensation" is one-fifth of the total compensation earned
by such Eligible  Trustee for  service to  the Adopting  Fund in  the five  year
period  prior to the  date of the Eligible  Trustee's retirement. Benefits under
the retirement program are not secured or funded by the Adopting Funds.
    
 
   
    The following  table  illustrates the  retirement  benefits accrued  to  the
Fund's  Independent Trustees by the  Fund for the fiscal  year ended October 31,
1996 and by the  57 Dean Witter  Funds (including the Fund)  as of December  31,
1995,  and the estimated retirement benefits for the Fund's Independent Trustees
from the Fund as  of October 31, 1996  and from the 57  Dean Witter Funds as  of
December 31, 1995.

(2)  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.

    varies depending on the Trustee's elections described in Footnote (2) above.
    
 
   
    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
- --------------------------------------------------------------------------------
 
    As  discussed in the  Prospectus, certain of  the U.S. Government securities
purchased by  the  Fund  are "mortgage-backed  securities",  which  evidence  an
interest  in a  specific pool  of mortgages. Such  securities are  issued by the
Government National  Mortgage Association  ("GNMA"), Federal  National  Mortgage
Association ("FNMA") and the Federal Home Loan Mortgage Corporation ("FHLMC").
 
    GNMA  CERTIFICATES.   GNMA Certificates evidence  an interest  in a specific
pool of mortgages insured by the  Federal Housing Administration ("FHA") or  the
Farmers Home Administration or guaranteed by the Veterans Administration ("VA").
Scheduled  payments of principal and interest are made to the registered holders
of GNMA Certificates. The GNMA Certificates that the Fund will invest in are  of
the  modified pass-through type.  GNMA guarantees the  timely payment of monthly
installments of principal and interest on modified pass-through certificates  at
the time such payments are due, whether or not such amounts are collected by the
issuer  on the underlying mortgages. The  National Housing Act provides that the
full faith and credit of the United  States is pledged to the timely payment  of
principal and interest by GNMA of amounts due on these GNMA Certificates.
 
    The  average life  of GNMA  Certificates varies  with the  maturities of the
underlying mortgage  instruments,  with  maximum maturities  of  30  years.  The
average  life is likely to  be substantially less than  the original maturity of
the mortgage pools  underlying the securities  as the result  of prepayments  or
 
                                       11
<PAGE>
refinancing  of  such  mortgages  or foreclosure.  Such  prepayments  are passed
through to the registered holder with the regular monthly payments of  principal
and  interest, which has the effect of reducing future payments. Due to the GNMA
guarantee, foreclosures impose no risk to principal investments.
 
    The average life  of pass-through pools  varies with the  maturities of  the
underlying  mortgage instruments. In addition, a pool's term may be shortened by
unscheduled or  early payments  of principal  on the  underlying mortgages.  The
occurrence  of mortgage prepayments is affected by  such factors as the level of
interest rates,  general  economic  conditions,  the location  and  age  of  the
mortgage  and other social and demographic  conditions. As prepayment rates vary
widely, it  is  not  possible  to  accurately predict  the  average  life  of  a
particular  pool. However, statistics indicate that the average life of the type
of mortgages  backing the  majority  of GNMA  Certificates is  approximately  12
years.  For this reason, it  is standard practice to  treat GNMA Certificates as
30-year mortgage-backed securities which prepay fully in the twelfth year. Pools
of mortgages  with  other  maturities or  different  characteristics  will  have
varying  assumptions  for average  life. The  assumed average  life of  pools of
mortgages having  terms  of less  than  30 years  is  less than  12  years,  but
typically not less than 5 years.
 
    The  coupon rate of interest of GNMA Certificates is lower than the interest
rate  paid  on  the  VA-guaranteed  or  FHA-insured  mortgages  underlying   the
Certificates,  but only by the  amount of the fees paid  to GNMA and the issuer.
Such fees in the aggregate usually amount to approximately .50 of 1%.
 
    Yields on pass-through securities are typically quoted by investment dealers
and vendors  based on  the  maturities of  the  underlying instruments  and  the
associated  average life assumption.  In periods of  falling interest rates, the
rate of prepayment tends to increase, thereby shortening the actual average life
of a  pool of  mortgage-related  securities. Conversely,  in periods  of  rising
rates,  the rate of prepayment tends to decrease, thereby lengthening the actual
average life of the pool. Reinvestment by  the Fund of prepayments may occur  at
higher  or  lower interest  rates  than the  original  investment. Historically,
actual average life has been consistent with the 12-year assumption referred  to
above. The actual yield of each GNMA Certificate is influenced by the prepayment
experience  of the mortgage  pool underlying the  Certificates. Interest on GNMA
Certificates is paid  monthly, rather  than semiannually,  as is  the case  with
traditional bonds.
 
    FHLMC SECURITIES.  The Federal Home Loan Mortgage Corporation was created in
1970  through enactment of Title III of  the Emergency Home Finance Act of 1970.
Its purpose  is to  promote  development of  a  nationwide secondary  market  in
conventional residential mortgages.
 
    The  FHLMC issues two  types of mortgage  pass-through securities, mortgages
participation  certificates  ("PCs")   and  guaranteed  mortgages   certificates
("GMCs").  PCs resemble GNMA Certificates in that  each PC represents a pro rata
share of all interest  and principal payments made  and owned on the  underlying
pool.  The FHMLC guarantees  timely monthly payment  of interest on  PCs and the
full return of principal when due. PCs  have an assumed average life similar  to
GNMA Certificates.
 
    GMCs  also represent a  pro rata interest  in a pool  of mortgages. However,
these instruments pay interest semi-annually and return principal once a year in
guaranteed minimum payments. The  expected average life  of these securities  is
approximately ten years.
 
    FNMA  SECURITIES.  The Federal National Mortgage Association was established
in 1938 to create a secondary market in mortgages insured by the FHA.
 
    FNMA   issues   guaranteed   mortgage   pass-through   certificates   ("FNMA
Certificates").  FNMA Certificates resemble GNMA  Certificates in that each FNMA
Certificate represents a pro rata share  of all interest and principal  payments
made and owed on the underlying pool. FNMA guarantees timely payment of interest
on FNMA Certificates and the full return of principal. FNMA Certificates have an
assumed average life similar to GNMA Certificates.
 
    LEVERAGING.   As discussed in the Prospectus, the Fund may borrow money, but
only from a bank and  in an amount up  to 25% of the  value of the Fund's  total
assets  taken at  the lower of  market value  or cost, not  including the amount
borrowed, in an effort to obtain additional income by leveraging its investments
through purchasing securities with the  borrowed funds. Such borrowings will  be
subject to
 
                                       12
<PAGE>
current margin requirements of the Federal Reserve Board and where necessary the
Fund may use any or all of its securities as collateral for such borrowings. Any
investment gains made with the additional monies in excess of interest paid will
cause  the net asset value of the Fund's shares to rise to a greater extent than
would otherwise be the  case. Conversely, if the  investment performance of  the
additional  monies fails to cover  their cost to the  Fund, net asset value will
decrease to a  greater extent  than would  otherwise be  the case.  This is  the
speculative factor involved in leverage.
 
    The  Fund  will be  required to  maintain an  asset coverage  (including the
proceeds of borrowings) of at least  300% of such borrowings in accordance  with
the  provisions of the Act. If, due to market fluctuations or other reasons, the
value of the Fund's assets (including the proceeds of borrowings) becomes at any
time less than three times  the amount of any  outstanding bank debt, the  Fund,
within three business days, will reduce its bank debt to the extent necessary to
meet the required 300% asset coverage. In restoring the 300% asset coverage, the
Fund  may have to  sell a portion  of its investments  at a time  when it may be
disadvantageous to do so.
 
    The investment policy  provides that  the Fund may  not purchase  or sell  a
security  on margin. The margin and bank borrowing restrictions will prevent the
ordinary purchase of a security which involves a cash borrowing from a broker of
any part of the purchase price of a security.
 
   
    The Fund may also borrow from banks as a temporary measure for extraordinary
or emergency purposes,  and for these  purposes and leveraging  combined, in  no
event  an amount greater than  25% of the value of  the Fund's total assets. The
Fund did not borrow any money during its fiscal year ended October 31, 1996.
    
 
    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 day's notice, or by
the  Fund on  two business days'  notice. If  the borrower fails  to deliver the
loaned securities within two  days after receipt of  notice, the Fund could  use
the  collateral to replace the securities  while holding the borrower liable for
any excess  of replacement  cost  over collateral.  As  with any  extensions  of
credit,  there are  risks of delay  in recovery and  in some cases  even loss of
rights in the collateral should the borrower of the securities fail financially.
However, these loans of portfolio securities  will only be made to firms  deemed
by  the Fund's management  to be creditworthy  and when the  income which can be
earned from such loans  justifies the attendant risks.  Upon termination of  the
loan, the borrower is required to return the securities to the Fund. Any gain or
loss  in the market  price during the loan  period would inure  to the Fund. The
creditworthiness of firms to which the Fund lends its portfolio securities  will
be  monitored  on  an  ongoing  basis  by  the  Investment  Manager  pursuant to
procedures adopted and reviewed, on an  ongoing basis, by the Board of  Trustees
of the Fund.
 
    When  voting or consent rights which accompany loaned securities pass to the
borrower, the Fund will follow the  policy of calling the loaned securities,  to
be  delivered within one day after notice, to permit the exercise of such rights
if the matters involved would have a material effect on the Fund's investment in
such loaned securities.  The Fund will  pay reasonable finder's,  administrative
and custodial fees in connection with a loan of its securities. The Fund has not
to date lent any of its portfolio securities.
 
    REPURCHASE  AGREEMENTS.  When cash may be  available for only a few days, it
may be invested by the Fund in  repurchase agreements until such time as it  may
otherwise  be invested or  used for payments  of obligations of  the Fund. These
agreements,  which  may  be  viewed  as  a  type  of  secured  lending  by   the
 
                                       13
<PAGE>
   
Fund,  typically involve the acquisition  by the Fund of  debt securities from a
selling financial institution such  as a bank, savings  and loan association  or
broker-dealer.  The  agreement provides  that  the Fund  will  sell back  to the
institution, and that the institution  will repurchase, the underlying  security
("collateral"),  which is held by the Fund's Custodian, 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.  If  such  decrease  occurs,
additional   collateral  will  be   added  to  the   account  to  maintain  full
collateralization. In the event the original seller defaults on its obligations,
the Fund will seek to sell the  collateral, which action could involve costs  or
delays. In such case, the Fund's ability to dispose of the collateral to recover
its investment may be restricted or delayed.
    
 
    The  Fund will accrue interest from the  institution until the time when the
repurchase is to  occur. Although  such date  is deemed by  the Fund  to be  the
maturity date of a repurchase agreement, the maturities of securities subject to
repurchase agreements are not subject to any limits. While repurchase agreements
involve certain risks not associated with direct investments in debt securities,
the  Fund follows procedures  designed to minimize  such risks. These procedures
include effecting repurchase transactions only with large, well-capitalized  and
well-established  financial  institutions,  whose  financial  condition  will be
continually monitored. In addition, the  value of the collateral underlying  the
repurchase  agreement will  always be  at least  equal to  the repurchase price,
including any accrued interest earned on the repurchase agreement. In the  event
of  a default or  bankruptcy by a  selling financial institution,  the Fund will
seek to liquidate such collateral. However,  the exercising of the Fund's  right
to  liquidate such collateral could involve certain  costs or delays and, to the
extent that  proceeds  from  any  sale  upon a  default  of  the  obligation  to
repurchase were less than the repurchase price, the Fund could suffer a loss. It
is the current policy of the Fund not to invest in repurchase agreements that do
not  mature within seven  days if any  such investment, together  with any other
illiquid assets held by the Fund, amounts to more than 10% of its total  assets.
The  Fund's investments  in repurchase  agreements may  at times  be substantial
when, in the view of the  Investment Manager, liquidity or other  considerations
warrant.
 
    REVERSE  REPURCHASE  AGREEMENTS AND  DOLLAR ROLLS.   The  Fund may  also use
reverse repurchase  agreements  and  dollar  rolls as  part  of  its  investment
strategy.  Reverse repurchase agreements involve sales  by the Fund of portfolio
assets concurrently with an agreement by the Fund to repurchase the same  assets
at a later date at a fixed price. Generally, the effect of such a transaction is
that  the Fund  can recover all  or most of  the cash invested  in the portfolio
securities involved during the term  of the reverse repurchase agreement,  while
it  will be  able to  keep the interest  income associated  with those portfolio
securities. Such transactions are only advantageous if the interest cost to  the
Fund  of the reverse repurchase  transaction is less than  the cost of obtaining
the cash otherwise. Opportunities  to achieve this advantage  may not always  be
available,  and the  Fund intends to  use the reverse  repurchase technique only
when it will be to its advantage to do so.
 
    The Fund may enter into dollar rolls in which the Fund sells securities  for
delivery  in  the  current  month  and  simultaneously  contracts  to repurchase
substantially similar (same type  and coupon) securities  on a specified  future
date.  During the roll period, the Fund  foregoes principal and interest paid on
the securities. The Fund  is compensated by the  difference between the  current
sales  price and the lower forward price for the future purchase (often referred
to as the "drop") as well as by the interest earned on the cash proceeds of  the
initial sale.
 
   
    The  Fund will establish a segregated account with its Custodian in which it
will maintain  cash or  cash equivalents  or other  liquid portfolio  securities
equal  in value to its obligations  in respect of reverse repurchase agreements.
Reverse repurchase agreements and dollar rolls are considered borrowings by  the
Fund  and for purposes other than meeting  redemptions may not exceed 10% of the
Fund's total assets.
    
 
    WHEN-ISSUED AND DELAYED  DELIVERY SECURITIES  AND FORWARD  COMMITMENTS.   As
discussed  in the Prospectus, from time to time 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
 
                                       14
<PAGE>
   
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.  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. The securities so purchased or sold are subject to market fluctuation
and no interest  or dividends accrue  to the purchaser  prior to the  settlement
date.  At the time the Fund makes  the commitment to purchase or sell securities
on a when-issued, delayed delivery or  forward commitment basis, it will  record
the  transaction and  thereafter reflect the  value, each day,  of such security
purchased or, if a  sale, the proceeds  to be received,  in determining its  net
asset  value. At the time of delivery of the securities, their value may be more
or less  than  the purchase  or  sale price.  The  Fund will  also  establish  a
segregated account with its custodian bank in which it will continually maintain
cash  or cash equivalents or other liquid portfolio securities equal in value to
commitments to purchase securities on a when-issued, delayed delivery or forward
commitment 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 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)  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 are listed on
Exchanges (currently the Chicago Board  Options Exchange and the American  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.
 
    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  member banks of  the Federal Reserve  System or  primary
U.S.  Government securities dealers or with  affiliates of such banks or dealers
which have capital of at least  $50 million or whose obligations are  guaranteed
by an entity having capital of at least $50 million.
 
    OPTIONS  ON TREASURY BONDS  AND NOTES.  Because  trading interest in options
written on Treasury bonds and notes tends to center mostly 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.
 
                                       15
<PAGE>
    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 it  will
be treated as being covered.
 
    OPTIONS  ON GNMA CERTIFICATES.  Currently,  options on GNMA Certificates are
only traded  over-the-counter. Since  the remaining  principal balance  of  GNMA
Certificates  declines each month as a result of mortgage payments, the Fund, as
a writer of  a GNMA call  holding GNMA  Certificates as "cover"  to satisfy  its
delivery   obligation  in  the  event  of  exercise,  may  find  that  the  GNMA
Certificates it holds no  longer have a  sufficient remaining principal  balance
for  this purpose.  Should this  occur, the  Fund will  purchase additional GNMA
Certificates from the same pool (if obtainable) or replacement GNMA Certificates
in the cash market in  order to maintain its cover.  A GNMA Certificate held  by
the Fund to cover an option position in any but the nearest expiration month may
cease  to represent cover for the  option in the event of  a decline in the GNMA
coupon rate at which new pools are  originated under the FHA/VA loan ceiling  in
effect  at any given time, as such  decline may increase the prepayments made on
other mortgage pools. If this should occur, the Fund will no longer be  covered,
and  the Fund will either  enter into a closing  purchase transaction or replace
such Certificate with a Certificate which represents cover. When the Fund closes
out its position or replaces such  Certificate, it may realize an  unanticipated
loss and incur transaction costs.
 
    RISKS  OF OPTIONS ON U.S. GOVERNMENT  SECURITIES.  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. 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 the  underlying securities at  the
exercise price.
 
    Prior  to exercise or expiration, an  option position can only be terminated
by entering  into a  closing purchase  or sale  transaction. If  a covered  call
option  writer is unable to effect a closing purchase transaction or to purchase
an offsetting  OTC option,  it cannot  sell the  underlying security  until  the
option  expires or the  option is exercised. Accordingly,  a covered call option
writer may not be able  to sell an underlying security  at a time when it  might
otherwise be advantageous to do so. A secured put option writer who is unable to
effect  a closing purchase  transaction or to purchase  an offsetting OTC option
would continue to bear the risk of decline in the market price of the underlying
security until the option  expires or is exercised.  In addition, a secured  put
writer  would be unable  to utilize the  amount held in  cash or U.S. Government
securities as security for  the put option for  other investment purposes  until
the exercise or expiration of the option.
 
    As discussed in the Prospectus, the Fund's ability to close out its position
as  a writer of an  exchange-listed option is dependent  upon the existence of a
liquid secondary market on Option Exchanges. 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
 
                                       16
<PAGE>
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.
 
    The hours  of trading  for options  on U.S.  Government securities  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.
 
   
    COVERED CALL WRITING.  The Fund  is permitted to write covered call  options
on portfolio securities, without limit. 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
premium received will fluctuate with varying economic market conditions. If  the
market  value  of the  portfolio securities  upon which  call options  have been
written increases, the Fund  may receive less total  return from the portion  of
its  portfolio upon which  calls have been  written than it  would have had such
calls not been written.
 
    As regards listed options and certain OTC options, during the option period,
the Fund  may be  required, at  any  time, to  deliver the  underlying  security
against  payment of the exercise price on  any calls it has written (exercise of
certain listed and  OTC options may  be limited to  specific expiration  dates).
This  obligation is terminated  upon the expiration  of the option  period or at
such earlier time  when the  writer effects  a closing  purchase transaction.  A
closing purchase transaction is accomplished by purchasing an option of the same
series  as  the  option previously  written.  However,  once the  Fund  has been
assigned an  exercise  notice, the  Fund  will be  unable  to effect  a  closing
purchase transaction.
 
    Closing purchase transactions are ordinarily effected to realize a profit on
an  outstanding call option to prevent an underlying security from being called,
to permit the  sale of an  underlying security or  to enable the  Fund to  write
another  call option on the underlying security with either a different exercise
price or expiration date or both. Also, effecting a closing purchase transaction
will permit the  cash or  proceeds from the  concurrent sale  of any  securities
subject to the option to be used for other investments by the Fund. The Fund may
realize  a net gain or  loss from a closing  purchase transaction depending upon
whether the amount of the  premium received on the call  option is more or  less
than  the cost of effecting the  closing purchase transaction. Any loss incurred
in a  closing  purchase  transaction  may  be  wholly  or  partially  offset  by
unrealized  appreciation  in  the  market  value  of  the  underlying  security.
Conversely, a gain resulting from a closing purchase transaction could be offset
in whole  or in  part  or exceeded  by a  decline  in the  market value  of  the
underlying security.
 
    If a call option expires unexercised, the Fund realizes a gain in the amount
of the premium on the option less the commission paid. Such a gain, however, may
be  offset by depreciation in the market value of the underlying security during
the option  period.  If  a  call  option  is  exercised,  the  Fund  realizes  a
 
                                       17
<PAGE>
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 on the option less the commission
paid.
 
   
    Options  written by a Fund normally have  expiration dates of up to eighteen
months from the date written. The exercise price of a call option may be  below,
equal  to or above  the current market  value of the  underlying security at the
time the option is written.
    
 
   
    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 put options written by the Fund will be
exercisable by the purchaser only on a specific date). A put is "covered" if, at
all times, the Fund maintains, in a segregated account maintained on its  behalf
at  the  Fund's  Custodian, cash,  U.S.  Government securities  or  other liquid
portfolio securities in an amount  equal to at least  the exercise price of  the
option, at all times during the option period. Similarly, a 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 writing puts, the Fund assumes the  risk
of  loss should the  market value of  the underlying security  decline below the
exercise price of the  option (any loss  being decreased by  the receipt of  the
premium on the option written). In the case of listed options, during the option
period,  the Fund may be required, at any  time, to make payment of the exercise
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
differences between the  exercise price  of the  option and  the current  market
price  of the  underlying securities  when the put  is exercised,  offset by the
premium received (less the commissions paid on the transaction).
 
    PURCHASING CALL AND PUT OPTIONS.  The Fund may purchase listed and OTC  call
and put options in amounts equalling up to 10% of its total assets. The Fund may
purchase  call options only in  order to close out  a covered call position (see
"Covered Call Writing" above). The  call purchased is likely  to be on the  same
securities and have the same terms as the written option.
 
    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 which is  sold.
Any  such gain or loss  could be offset in  whole or in part  by a change in the
market value of the underlying security. If  a put option purchased by the  Fund
expired without being sold or exercised, the premium would be lost.
 
    RISKS  OF OPTIONS TRANSACTIONS.  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
 
                                       18
<PAGE>
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 secured put option writer who is unable to
effect  a closing purchase  transaction or to purchase  an offsetting OTC option
would continue to bear the risk of decline in the market price of the underlying
security until the option  expires or is exercised.  In addition, a secured  put
writer  would be unable  to utilize the  amount held in  cash or U.S. Government
securities or other liquid portfolio securities  as security for the put  option
for other investment purposes until the exercise or expiration of the option.
    
 
    The  Fund's ability to  close out its position  as a writer  of an option is
dependent upon the existence of a  liquid secondary market on option  exchanges.
There is no assurance that such a market will exist, particularly in the case of
OTC  options, as such options will generally only be closed out by entering into
a closing purchase transaction with the purchasing dealer. However, the Fund may
be able to purchase an offsetting option  which does not close out its  position
as  a writer but constitutes an asset of equal value to the obligation under the
option written. If the Fund is not able to either enter into a closing  purchase
transaction  or purchase an offsetting position, it will be required to maintain
the securities subject to the call,  or the collateral underlying the put,  even
though it might not be advantageous to do so, until a closing transaction can be
entered into (or the option is exercised or expires).
 
    Among  the possible reasons for the absence  of a liquid secondary market on
an Exchange  are: (i)  insufficient trading  interest in  certain options;  (ii)
restrictions  on  transactions  imposed  by an  Exchange;  (iii)  trading halts,
suspensions or other restrictions imposed with respect to particular classes  or
series  of options  or underlying  securities; (iv)  interruption of  the normal
operations on an Exchange;  (v) inadequacy of the  facilities of an Exchange  or
the  Options Clearing Corporation  ("OCC") to handle  current trading volume; or
(vi) a decision by one or more  Exchanges to discontinue the trading of  options
(or  a particular  class or  series of  options), in  which event  the secondary
market on that Exchange (or in that  class or series of options) would cease  to
exist, although outstanding options on that Exchange that had been issued by the
OCC  as  a result  of trades  on that  Exchange would  generally continue  to be
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.
 
                                       19
<PAGE>
    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.
 
    INTEREST RATE FUTURES CONTRACTS.  As a purchaser of an interest rate futures
contract ("futures contract"), the Fund incurs an obligation to take delivery of
a specified  amount of  the  obligation underlying  the  futures 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 futures contracts for the purpose of hedging
its  portfolio  (or  anticipated   portfolio)  securities  against  changes   in
prevailing  interest rates. If the  Investment Manager anticipates that interest
rates may rise and, concomitantly, the price of U.S. Government securities fall,
the  Fund  may  sell  a  futures  contract.  If  declining  interest  rates  are
anticipated,  the  Fund may  purchase a  futures contract  to protect  against a
potential increase in the price of  U.S. Government securities the Fund  intends
to  purchase.  Subsequently,  appropriate  U.S.  Government  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. In addition,  futures contracts will  be bought or  sold in order  to
close out a short or long position in a corresponding futures contract.
 
    Although  most futures contracts  call for actual  delivery or acceptance of
securities, the  contracts usually  are closed  out before  the settlement  date
without  the making or taking of delivery. A futures contract sale is closed out
by effecting a futures  contract purchase for the  same aggregate amount of  the
specific  type of security and the same delivery date. If the sale price exceeds
the offsetting purchase price, the seller would be paid the difference and would
realize a gain.  If the offsetting  purchase price exceeds  the sale price,  the
seller  would pay the difference and would  realize a loss. Similarly, a futures
contract purchase is  closed out by  effecting a futures  contract sale for  the
same  aggregate amount of  the specific type  of security 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.
 
   
    When  the Fund enters  into a futures  contract it is  initially required to
deposit with its Custodian, in  a segregated account in  the name of the  broker
performing  the  transaction  an "initial  margin"  of cash  or  U.S. Government
securities or other liquid portfolio securities equal to approximately 2% of the
contract amount. Initial margin requirements are established by the Exchanges on
which futures contracts trade and may,  from time to time, change. In  addition,
brokers may establish margin deposit requirements in excess of those required by
the Exchanges.
    
 
    Initial   margin  in  futures  transactions  is  different  from  margin  in
securities transactions in that initial margin does not involve the borrowing of
funds by a brokers' client but is,  rather, a good faith deposit on the  futures
contract  which will be returned to the  Fund upon the proper termination of the
futures contract. The margin  deposits made are marked  to market daily and  the
Fund  may be required  to make subsequent deposits  into the segregated account,
maintained at  its  Custodian for  that  purpose,  of cash  or  U.S.  Government
securities,  called "variation  margin," in  the name  of the  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.
 
    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),  and the  writer  the obligation,  to  assume a
position in a futures contract  (a long position if the  option is a call and  a
short position if the option is a put) at a specified exercise price at any time
during  the term of the option. Upon exercise of the option, the delivery of the
futures position by
 
                                       20
<PAGE>
the writer of the option to the holder of the option is accompanied by  delivery
of  the  accumulated  balance  in the  writer's  futures  margin  account, which
represents the amount by which the market  price of the futures contract at  the
time of exercise exceeds, in the case of a call, or is less than, in the case of
a put, the exercise price of the option on the futures contract.
 
    The  Fund will purchase and write options on futures contracts for identical
purposes to  those  set forth  above  for the  purchase  of a  futures  contract
(purchase  of a call option or  sale of a put option)  and the sale of a futures
contract (purchase of a put option or sale of a call option), or to close out  a
long  or short  position in futures  contracts. If, for  example, the Investment
Manager wished  to  protect  against  an increase  in  interest  rates  and  the
resulting  negative impact  on the  value of  a portion  of its  U.S. Government
securities 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 margin plus the amount paid for premiums for
unexpired  options on futures  contracts exceeds 5%  of the value  of the Fund's
total assets, after taking into  account unrealized gains and unrealized  losses
on such contracts it has entered into, provided, however, that in the case of an
option that is in-the-money (the exercise price of the call (put) option is less
(more)  than  the  market price  of  the  underlying security)  at  the  time of
purchase, the  in-the-money  amount  may  be excluded  in  calculating  the  5%.
However,  there is no overall limitation on  the percentage of the Fund's assets
which may be subject to  a hedge position. In  addition, in accordance with  the
regulations of the Commodity Futures Trading Commission ("CFTC") under which the
Fund  is exempted from registration  as a commodity pool  operator, the Fund may
only enter into futures contracts and options on futures contracts  transactions
for  purposes of hedging a part or all of its portfolio. If the CFTC changes its
regulations so that  the Fund  would be permitted  to write  options on  futures
contracts  for purposes other  than hedging the  Fund's investments without CFTC
registration, the  Fund may  engage  in such  transactions for  those  purposes.
Except  as described above, there are no other limitations on the use of futures
and options thereon by the Fund.
 
    RISKS OF TRANSACTIONS IN FUTURES CONTRACTS  AND RELATED OPTIONS.  As  stated
in  the Prospectus, the Fund may sell  a futures contract to protect against the
decline in the value of U.S. Government securities held by the Fund. However, it
is possible that the futures market may advance and the value of securities held
in the Fund's portfolio may decline. If this were to occur, the Fund would  lose
money  on the futures  contracts and also  experience a decline  in value in its
portfolio securities. However, while this could occur for a very brief period or
to a very  small degree,  over time  the market prices  of the  securities of  a
diversified  portfolio will tend to move in  the same direction as the prices of
futures contracts.
 
    If the Fund purchases  a futures contract to  hedge against the increase  in
value  of U.S. Government  securities it intends  to buy, and  the value of such
securities decreases,  then  the  Fund  may  determine  not  to  invest  in  the
securities  as planned and will  realize a loss on  the futures contract that is
not offset by a reduction in the price of the securities.
 
    In order to assure  that the Fund is  entering into transactions in  futures
contracts  for hedging  purposes as such  is defined by  the Commodities Futures
Trading Commission either: (1) a substantial majority (i.e., approximately  75%)
of  all anticipatory hedge transactions (transactions in which the Fund does not
own at  the time  of the  transaction, but  expects to  acquire, the  securities
underlying  the  relevant futures  contract) involving  the purchase  of futures
contracts will be completed by the purchase of securities which are the  subject
of  the hedge,  or (2)  the underlying  value of  all long  positions in futures
 
                                       21
<PAGE>
contracts will not exceed the total value of (a) all short-term debt obligations
held by the Fund; (b) cash held by  the Fund; (c) cash proceeds due to the  Fund
on  investments within thirty  days; (d) the margin  deposited on the contracts;
and (e) any unrealized appreciation in the value of the contracts.
 
    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, or  by
holding  a call option  permitting the Fund  to purchase the  same contract at a
price no higher than the price at which the short position was established.
 
   
    In addition, if the Fund holds a long position in a futures contract or  has
sold  a put  option on a  futures contract,  it will hold  cash, U.S. Government
securities or other liquid portfolio securities  equal to the purchase price  of
the contract or the exercise price of the put option (less the amount of initial
or  variation margin on deposit) in a segregated account maintained for the Fund
by its  Custodian. Alternatively,  the Fund  could cover  its long  position  by
purchasing  a put option on the same  futures contract with an exercise price as
high or higher than the price of the contract held by the Fund.
    
 
    Exchanges limit the amount by which the price of a futures contract may move
on any day. If the price moves equal the daily limit on successive days, then it
may prove impossible to liquidate a futures position until the daily limit moves
have ceased. In the event of adverse price movements, the Fund would continue to
be required to  make daily  cash payments of  variation margin  on open  futures
positions. In such situations, if the Fund has insufficient cash, it may have to
sell  portfolio securities to meet daily variation margin requirements at a time
when it may be disadvantageous to do  so. In addition, the Fund may be  required
to  take or  make delivery of  the instruments underlying  interest rate futures
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  broker
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
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   relationships  between  the  debt
securities and futures market 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
 
                                       22
<PAGE>
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  U.S. Government 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.
 
    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 contracts or underlying U.S. Government 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.
 
PORTFOLIO TURNOVER
 
    The  Fund may sell portfolio securities without regard to the length of time
they have  been  held whenever  such  sale  will, in  the  Investment  Manager's
opinion,  strengthen  the  Fund's  position  and  contribute  to  its investment
objective. As  a result,  the Fund's  portfolio turnover  rate may  exceed  100%
(although it is not anticipated to do so). A 100% turnover rate would occur, for
example,  if 100% of the securities held  in the Fund's portfolio (excluding all
securities whose maturities at acquisition were one year or less) were sold  and
replaced within one year.
 
INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------
 
    In addition to the investment restrictions enumerated in the Prospectus, the
investment   restrictions  listed  below  have  been  adopted  by  the  Fund  as
fundamental  policies,  except  as  otherwise   indicated.  Under  the  Act,   a
fundamental  policy may  not be changed  without the  vote of a  majority of the
outstanding voting  securities  of the  Fund,  as defined  in  the Act.  Such  a
majority  is defined as the lesser of (a) 67% or more of the shares present at a
meeting of shareholders, if the holders of 50% of the outstanding shares of  the
Fund are present or represented by proxy or (b) more than 50% of the outstanding
shares of the Fund.
 
    The Fund may not:
 
         1. Invest in securities of any issuer if, to the knowledge of the Fund,
    any  officer or  trustee/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 issuer.
 
         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.
 
                                       23
<PAGE>
         3.  Purchase  oil,  gas  or other  mineral  leases,  rights  or royalty
    contracts, or exploration or development programs, except that the Fund  may
    invest  in the securities of companies  which operate, invest in, or sponsor
    such programs.
 
         4.  Purchase  securities  of  other  investment  companies,  except  in
    connection  with a  merger, consolidation, reorganization  or acquisition of
    assets.
 
         5. Issue senior securities as defined in the Act, except insofar as the
    Fund may  be deemed  to have  issued a  senior security  by reason  of:  (a)
    entering  into any reverse repurchase agreement; (b) borrowing money; or (c)
    purchasing any  securities on  a when-issued,  delayed delivery  or  forward
    commitment basis.
 
         6.  Make loans of money  or securities, except: (a)  by the purchase of
    publicly  distributed  debt  obligations  in  which  the  Fund  may   invest
    consistent with its investment objectives and policies; (b) by investment in
    repurchase  or reverse purchase agreements; or  (c) by lending its portfolio
    securities.
 
         7. 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.
 
         8.  Invest for the  purpose of exercising control  or management of any
    other issuer.
 
         9. 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.
 
        10. Make short sales of securities or maintain a short position,  unless
    at  all times when a short position is  open it owns an equal amount of such
    securities or securities convertible  into or exchangeable, without  payment
    of any further consideration, for securities of the same issue as, and equal
    in amount to, the securities sold short, and unless not more than 10% of the
    Fund's  net assets (taken  at market value)  is held as  collateral for such
    sales at any one  time (it is  the present intention  of management to  make
    such sales only for the purpose of deferring realization of gain or loss for
    Federal  income tax  purposes; such  sales would  not be  made of securities
    subject to outstanding options).
 
    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 the foregoing restrictions.
 
PORTFOLIO TRANSACTIONS AND BROKERAGE
- --------------------------------------------------------------------------------
 
   
    Subject to  the  general  supervision  of the  Trustees  of  the  Fund,  the
Investment  Manager is responsible for the  investment decisions and the placing
of the orders  for portfolio  transactions for  the Fund.  The Fund's  portfolio
transactions will occur primarily with issuers, underwriters or major dealers in
U.S.  Government securities acting as principals. Such transactions are normally
on a net basis and do not involve payment of brokerage commissions. The cost  of
securities  purchased from an underwriter usually  includes a commission paid by
the issuer to the underwriters;  transactions with dealers normally reflect  the
spread  between  bid and  asked prices.  Options  and futures  transactions will
usually be effected through  a broker and a  commission will be charged.  During
the fiscal years ended October 31, 1994, 1995 and 1996, the Fund paid a total of
$104,215, $111,547 and $109,449, 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 or  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 are  considered, including  the  respective investment  objectives,  the
relative    size   of   portfolio   holdings   of   the   same   or   comparable
    
 
                                       24
<PAGE>
   
securities, the  availability of  cash for  investment, the  size of  investment
commitments  generally  held and  the opinions  of  the persons  responsible for
managing the portfolios of the  Fund and other client  accounts. In the case  of
certain  initial  and secondary  public  offerings, the  Investment  Manager may
utilize a pro-rata allocation process based on the size of the Dean Witter Funds
involved and the number of shares available from the public offering.
    
 
   
    The policy  of the  Fund regarding  purchases and  sales of  securities  and
futures  contracts for its portfolio is that primary consideration will be given
to obtaining the most favorable prices and efficient execution of  transactions.
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 price  and execution  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 October 31, 1996, the Fund  did not direct the payment of any
brokerage commissions because of research services provided.
    
 
    The information and services received by the Investment Manager from brokers
and dealers may be  of benefit to  the Investment Manager  in the management  of
accounts  of some of its other clients and may not in all cases benefit the Fund
directly. While  the receipt  of  such information  and  services is  useful  in
varying  degrees and would  generally reduce the amount  of research or services
otherwise performed by the Investment  Manager and thereby reduce its  expenses,
it  is of  indeterminable value  and the management  fee paid  to the Investment
Manager is not reduced by  any amount that may be  attributable to the value  of
such services.
 
    Pursuant to an order of the Securities and Exchange Commission, the Fund may
effect  principal transactions in certain money market instruments with DWR. The
Fund will limit  its transactions  with DWR  to U.S.  Government and  Government
Agency  Securities, Bank  Money Instruments  (I.E., Certificates  of Deposit and
Bankers' Acceptances) and Commercial Paper.  Such transactions will be  effected
with  DWR only when the  price available from DWR  is better than that available
from other dealers.
 
   
    Consistent with  the  policy  described  above,  brokerage  transactions  in
securities listed on exchanges or admitted to unlisted trading privileges may be
effected  through DWR. In order for DWR to effect portfolio transactions for the
Fund, the  commissions, fees  or  other remuneration  received  by DWR  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 DWR to  receive no more  than the remuneration
which would  be  expected  to  be  received  by  an  unaffiliated  broker  in  a
commensurate  arm's-length transaction.  Furthermore, the Trustees  of the Fund,
including a majority  of the Trustees  who are not  "interested" Trustees,  have
adopted   procedures  which  are   reasonably  designed  to   provide  that  any
commissions, fees or  other remuneration  paid to  DWR are  consistent with  the
foregoing  standard. During  the fiscal years  ended October 31,  1994, 1995 and
1996, the Fund  paid a  total of $10,971,  $9,495 and  $8,477, respectively,  in
brokerage  commissions to DWR.  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  DWR.  During the  fiscal  year ended  October  31, 1996,  the  brokerage
commissions  paid to DWR represented approximately  7.74% of the total brokerage
commissions paid  by the  Fund  during the  year and  were  paid on  account  of
transactions  having an aggregate  dollar value equal  to approximately 9.73% of
the aggregate dollar value of all portfolio transactions of the Fund during  the
year for which commissions were paid. In addition, during the fiscal years ended
October 31, 1994, 1995 and 1996, the Fund paid DWR $81,776, $80,741 and $69,669,
respectively, for clearing options and futures transactions.

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 DWDC. 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 October 30, 1992,
the current  Distribution  Agreement  appointing the  Distributor  as  exclusive
distributor  of  the Fund's  shares and  providing for  the Distributor  to bear
distribution expenses not borne by the Fund. The current Distribution  Agreement
is  substantively identical to  the Fund's previous  distribution agreements. By
its terms, the Distribution Agreement had an initial term ending April 30, 1994,
and will remain in effect from year to year thereafter if approved by the Board.
At their meeting  held on April  17, 1996,  the Trustees, including  all of  the
Independent  Trustees, approved  the continuation of  the Distribution Agreement
until April 30, 1997.
    
 
    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 to prospective shareholders. The Fund bears
the  costs of initial typesetting, printing and distribution of prospectuses and
supplements thereto to shareholders. The Fund bears the costs of registering the
Fund and its shares under  federal and state securities  laws. The Fund and  the
Distributor  have agreed  to indemnify  each other  against certain liabilities,
including liabilities under the  Securities Act of 1933,  as amended. Under  the
Distribution  Agreement,  the Distributor  uses  its best  efforts  in rendering
services to the  Fund, but  in the absence  of willful  misfeasance, bad  faith,
gross  negligence or reckless  disregard of its  obligations, the Distributor is
not liable to the Fund or any of its shareholders for any error of judgement  or
mistake  of law or  for any act of  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 the Fund  pays the Distributor  compensation
accrued  daily and payable monthly at the annual rate of 0.85% of the lesser of:
(a) the  average daily  aggregate gross  sales of  the Fund's  shares since  the
inception   of   the  Fund   (not   including  reinvestment   of   dividends  or
distributions), less the average daily aggregate  net asset value of the  Fund's
shares  redeemed since  the Fund's  inception upon  which a  contingent deferred
sales charge has been  imposed or waived,  or (b) the  Fund's average daily  net
assets.  The Distributor also receives the proceeds of contingent deferred sales
charges imposed on certain redemptions of  shares, which are separate and  apart
from  payments made  pursuant to the  Plan (see "Redemptions  and Repurchases --
Contingent Deferred  Sales  Charge"  in the  Prospectus).  The  Distributor  has
informed  the Fund that it and/or  DWR received approximately $822,000, $750,000
and $641,000 in  contingent deferred sales  charges for the  fiscal years  ended
October 31, 1994, 1995 and 1996, respectively, none of which was retained by the
Distributor.
    
 
    The  Distributor has informed the Fund that a portion of the fees payable by
the Fund each year  pursuant to the  Plan equal to 0.20%  of the Fund's  average
daily  net assets is  characterized as a  "service fee" under  the Rules of Fair
Practice of the National Association of  Securities Dealers, Inc. (of which  the
Distributor is a member). Such portion of the fee is a payment made for personal
service and/or the maintenance of shareholder accounts. The remaining portion of
the  Plan fees  payable by  the Fund is  characterized as  an "asset-based sales
charge" as such is defined by the aforementioned Rules of Fair Practice.
 
                                       26
<PAGE>
    The  Plan was adopted by a majority vote of the Board of Trustees, including
all of the Trustees of the Fund who are not "interested persons" of the Fund (as
defined in the Act) and who have no direct or indirect financial interest in the
operation of the Plan  (the "Independent 12b-1 Trustees"),  cast in person at  a
meeting  called for the purpose of voting on  the Plan, on December 15, 1986, by
DWR as the  then sole shareholder  of the Fund  on January 13,  1987 and by  the
shareholders  holding  a majority,  as defined  in the  Act, of  the outstanding
voting securities of the Fund at a  Special Meeting of Shareholders of the  Fund
held on May 31, 1988.
 
    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  the  reorganization  described  above  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,  approved
certain  technical amendments to the Plan  in connection with amendments adopted
by the National  Association of Securities  Dealers, Inc. to  its Rules of  Fair
Practice.  At their meeting held on October  26, 1995, the Trustees of the Fund,
including all of the  Independent 12b-1 Trustees, approved  an amendment to  the
Plan  to  permit payments  to be  made under  the Plan  with respect  to certain
distribution expenses incurred  in connection with  the distribution of  shares,
including  personal services  to shareholders with  respect to  holdings of such
shares, of an  investment company whose  assets are  acquired by the  Fund in  a
tax-free reorganization.
 
   
    Under  the Plan  and as  required by  Rule 12b-1,  the Trustees  receive and
review promptly after the end of each calendar quarter a written report provided
by the Distributor of the  amounts expended under the  Plan and the purpose  for
which  such  expenditures were  made. The  Fund accrued  amounts payable  to the
Distributor and DWR  under the Plan,  during the fiscal  year ended October  31,
1996,  of $6,554,450. This amount is equal  to 0.85% of the Fund's average daily
net assets for the fiscal year and was calculated pursuant to clause (b) of  the
compensation  formula under the Plan.  This amount is treated  by the Fund as an
expense in the year it is accrued.
    
 
    The Plan was  adopted in order  to permit the  implementation of the  Fund's
method  of distribution. Under this distribution  method, shares of the Fund are
sold without a sales load  being deducted at the time  of purchase, so that  the
full amount of an investor's purchase payment will be invested in shares without
any  deduction  for  sales charges.  Shares  of the  Fund  may be  subject  to a
contingent deferred sales charge, payable to the Distributor, if redeemed during
the six years after  their purchase. DWR compensates  its account executives  by
paying  them, from its own funds, commissions for the sale of the Fund's shares,
currently a gross  sales credit of  up to 4%  of the amount  sold and an  annual
residual  commission of  up to 0.20  of 1%  of the current  value (not including
reinvested dividends  or distributions)  of  the amount  sold. The  gross  sales
credit  is  a charge  which  reflects commissions  paid  by DWR  to  its account
executives and DWR's  Fund associated  distribution-related expenses,  including
sales  compensation, and  overhead and other  branch office distribution-related
expenses including:  (a)  the expenses  of  operating DWR's  branch  offices  in
connection with the sale of Fund shares, including lease costs, the salaries and
employee  benefits  of operations  and sales  support personnel,  utility costs,
communications costs and the costs of stationery and supplies, (b) the costs  of
client  sales seminars, (c) travel expenses of mutual fund sales coordinators to
promote the  sale of  Fund shares  and  (d) other  expenses relating  to  branch
promotion of Fund sales. The distribution fee that the Distributor receives from
the Fund under the Plan, in effect, offsets distribution expenses incurred under
the  Plan on behalf of  the Fund and 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, 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 charge received
 
                                       27
<PAGE>
by  the Distributor  upon redemption  of shares of  the Fund.  No other interest
charge is included as a distribution expense in the Distributor's calculation of
its distribution costs for this purpose. The broker's call rate is the  interest
rate   charged  to  securities  brokers  on  loans  secured  by  exchange-listed
securities.
 
   
    The Fund paid 100% of the $6,554,450  accrued under the Plan for the  fiscal
year ended October 31, 1996 to the Distributor. The Distributor and DWR estimate
that  they have spent, pursuant to the  Plan, $176,271,676 on behalf of the Fund
since the inception of the Plan. It  is estimated that this amount was spent  in
approximately  the  following ways:  (i) 2.44%  ($4,301,263) --  advertising and
promotional expenses;  (ii) 0.23%  ($400,898) --  printing of  prospectuses  for
distribution to other than current shareholders; and (iii) 97.33% ($171,569,515)
- --  other expenses, including the gross sales credit and the carrying charge, of
which 17.10%  ($29,336,832) represents  carrying charges,  33.44%  ($57,376,664)
represents  commission credits to DWR branch offices for payments of commissions
to account executives  and 49.46%  ($84,856,019) represents  overhead and  other
branch office distribution-related expenses.
    
 
   
    At  any given time, the  expenses of distributing shares  of the Fund may be
more or less than the total of (i) the payments made by the Fund pursuant to the
Plan and  (ii)  the  proceeds  of contingent  deferred  sales  charges  paid  by
investors  upon redemption of shares. The  Distributor has advised the Fund that
the excess 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 shares, totalled $27,489,031 as of October 31, 1996. 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, this excess  amount does not constitute  a liability of the  Fund.
Although  there is no legal obligation for  the Fund to pay expenses incurred in
excess of payments made to  the Distributor under the  Plan and the proceeds  of
contingent  deferred sales charges paid by  investors upon redemption of shares,
if for any reason  the Plan is  terminated, the Trustees  will consider at  that
time  the  manner  in which  to  treat  such expenses.  Any  cumulative expenses
incurred, but not yet recovered through distribution fees or contingent deferred
sales charges, may or may not  be recovered through future distribution fees  or
contingent deferred sales charges.
    
 
    No  interested person of the Fund nor any  Trustee of the Fund who is not an
interested person of the Fund, as defined  in the Act, has any direct  financial
interest in the operation of the Plan except to the extent that the Distributor,
InterCapital,  DWR or certain of  their employees may be  deemed to have such an
interest as a result  of benefits derived from  the successful operation of  the
Plan or as a result of receiving a portion of the amounts expended thereunder by
the Fund.
 
   
    Under  its terms, the Plan remained in  effect until April 30, 1987 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. The most
recent continuance of the Plan for one year, until April 30, 1997, was  approved
by  the Board of Trustees  of the Fund, including  a majority of the Independent
12b-1 Trustees, at a Board  meeting held on April  17, 1996. Prior to  approving
the  continuation  of the  Plan, the  Trustees requested  and received  from the
Distributor and  reviewed all  the information  which they  deemed necessary  to
arrive  at an informed determination. In  making their determination to continue
the Plan, the Trustees considered: (1) the Fund's experience under the Plan  and
whether such experience indicates that the Plan is operating as anticipated; (2)
the  benefits the Fund had obtained, was obtaining and would be likely to obtain
under the Plan; and (3) what services  had been provided and were continuing  to
be  provided under the Plan  to the Fund and  its shareholders. Based upon their
review, the  Trustees of  the  Fund, including  each  of the  Independent  12b-1
Trustees, determined that continuation of the Plan would be in the best interest
of  the Fund and would have a reasonable likelihood of continuing to benefit the
Fund and its shareholders. In the  Trustees' quarterly review of the Plan,  they
will  consider  its  continued  appropriateness and  the  level  of compensation
provided herein.
    
 
    The Plan may not be  amended to increase materially  the amount to be  spent
for  the services described therein without  approval by the shareholders of the
Fund, and all material amendments to the
 
                                       28
<PAGE>
Plan must also be approved  by the Trustees in  the manner described above.  The
Plan may be terminated at any time, without payment of any penalty, by vote of a
majority  of the Independent  12b-1 Trustees or by  a vote of  a majority of the
outstanding voting securities of the  Fund (as defined in  the Act) on not  more
than  thirty days' written notice to any other  party to the Plan. The Plan will
automatically terminate in the event of its assignment (as defined in the  Act).
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 debt  securities  with remaining
maturities of sixty days or less at the time of purchase are valued at amortized
cost, unless the Trustees determine such does not reflect the securities' market
value, in which  case these securities  will be  valued at their  fair value  as
determined by the Trustees. Other short-term debt securities will be valued on a
mark-to-market basis until such time as they reach a remaining maturity of sixty
days,  whereupon they will be valued at  amortized cost using their value on the
61st day unless  the Trustees determine  such does not  reflect the  securities'
market  value, in which case these securities will be valued at their fair value
as determined by  the Trustees.  Listed options are  valued at  the latest  sale
price  on the exchange on which they are  listed unless no sales of such options
have taken place that day, in which case they will be valued at the mean between
their latest  bid and  asked prices.  Unlisted options  are valued  at the  mean
between their latest bid and asked prices. Futures are valued at the latest sale
price  on  the commodities  exchange  on which  they  trade unless  the Trustees
determine such price  does not reflect  their market value,  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.
 
    As stated in the Prospectus, the Investment Manager will compute the  Fund's
net  asset value 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; Presidents' Day; Good
Friday; Memorial  Day;  Independence  Day;  Labor  Day;  Thanksgiving  Day;  and
Christmas Day.
 
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 Fund's
Transfer Agent, Dean  Witter Trust Company  (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  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 Fund (or  in
cash  if the shareholder so requests) as of the close of business on the monthly
payment date, as stated in the Prospectus.  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 payment  date of  the
dividend   or   the   record   date   of   the   distribution.   In   the   case
 
                                       29
<PAGE>
of recently purchased shares for  which registration instructions have not  been
received  on the payment  or record date, cash  payments will be  made to DWR or
other selected broker-dealer, and will be forwarded to the shareholder, upon the
receipt of proper instructions.
 
    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 an open-end Dean Witter Fund other than Dean
Witter Federal Securities Trust. Such investment will be made as described above
for automatic investment in shares of the Fund, at the net asset value per share
of the selected  Dean Witter Fund  as of the  close of business  on the  monthly
payment  date 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  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, 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.  For further  information  or to  subscribe  to
EasyInvest,   shareholders   should  contact   their   DWR  or   other  selected
broker-dealer account executive or the Transfer Agent.
 
    INVESTMENT OF DIVIDENDS OR DISTRIBUTIONS RECEIVED IN CASH.  As discussed  in
the  Prospectus,  any shareholder  who receives  a  cash payment  representing a
dividend or distribution may invest such  dividend or distribution at net  asset
value,  without  the  imposition  of a  contingent  deferred  sales  charge 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 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  contingent deferred  sales  charge  will  be
imposed  on  shares redeemed  under the  Withdrawal  Plan (see  "Redemptions and
Repurchases -- Contingent  Deferred Sales Charge").  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  contingent
deferred  sales charge)  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  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
 
                                       30
<PAGE>
$2,500 or more  under the  Withdrawal Plan, withdrawals  made concurrently  with
purchases  of additional  shares may  be inadvisable  because of  the contingent
deferred sales charge applicable  to the redemption  of shares purchased  during
the  preceding six years (see "Redemption and Repurchases -- Contingent Deferred
Sales Charge").
 
    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  INVESTMENTS THROUGH TRANSFER AGENT.  As discussed in the Prospectus,
a shareholder may make additional investments in Fund shares at any time through
a Shareholder Investment Account by sending a check in any amount, not less than
$100, directly to the Fund's Transfer Agent. Such amounts will be applied to the
purchase of Fund shares at the net  asset value per share next determined  after
receipt  of the check or  purchase payment by the  Transfer Agent. The shares so
purchased will be credited to the investment account.
 
EXCHANGE PRIVILEGE
 
    As discussed in the Prospectus, the Fund makes available to its shareholders
an Exchange Privilege whereby shareholders of the Fund may exchange their shares
for shares of  other Dean  Witter Funds sold  with a  contingent deferred  sales
charge  ("CDSC funds"), and  for shares of Dean  Witter Short-Term U.S. Treasury
Trust, Dean Witter  Limited Term  Municipal Trust, Dean  Witter Short-Term  Bond
Fund,  Dean Witter Balanced Growth Fund,  Dean Witter Balanced Income Fund, Dean
Witter Intermediate Term U.S.  Treasury Trust and five  Dean Witter Funds  which
are  money market  funds (the  foregoing eleven  non-CDSC funds  are hereinafter
referred to as the "Exchange Funds"). Exchanges may be made after the shares  of
the  Fund acquired by  purchase (not by exchange  or dividend reinvestment) have
been held for thirty days.  There is no waiting  period for exchanges of  shares
acquired  by exchange or dividend reinvestment.  An exchange will be treated for
federal income tax purposes the same as a repurchase or redemption of shares, on
which the shareholder may realize a capital gain or loss.
 
    Any new account  established through  the Exchange Privilege  will have  the
same registration and cash dividend or dividend reinvestment plan as the present
account,  unless  the  Transfer  Agent  receives  written  notification  to  the
contrary. For  telephone  exchanges,  the exact  registration  of  the  existing
account and the account number must be provided.
 
    Any  shares  held  in  certificate  form cannot  be  exchanged  but  must be
forwarded to the  Transfer Agent  and deposited into  the shareholder's  account
before  being eligible for exchange. (Certificates  mailed in for deposit should
not be endorsed.)
 
   
    As described  below, and  in  the Prospectus  under the  captions  "Exchange
Privilege"  and "Contingent Deferred Sales  Charge," a contingent deferred sales
charge ("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  the Fund or  any
other  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"
    
 
                                       31
<PAGE>
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  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
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  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 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 CDSC fund.
 
    In  addition, shares of the  Fund may be acquired  in exchange for shares of
Dean Witter Funds sold  with a front-end sales  charge ("front-end sales  charge
funds"),  but shares  of the  Fund, however acquired,  may not  be exchanged for
shares of  front-end sales  charge funds.  Shares  of a  CDSC fund  acquired  in
exchange  for shares of a front-end sales charge fund (or in exchange for shares
of other Dean Witter  Funds for which  shares of a  front-end sales charge  fund
have been exchanged) are not subject to any CDSC upon their redemption.
 
   
    When  shares initially purchased in a CDSC  fund are exchanged for shares of
another CDSC fund, or for  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 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  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 (all such shares called "Free
Shares"), will be  exchanged first. Shares  of Dean Witter  American Value  Fund
acquired  prior  to  April  30,  1984, shares  of  Dean  Witter  Dividend Growth
Securities Inc. and  Dean Witter  Natural Resource  Development Securities  Inc.
acquired  prior  to July  2, 1984,  and  shares of  Dean Witter  Strategist Fund
acquired prior to November 8, 1989, are also considered Free Shares and will  be
the  first Free Shares to be exchanged.  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  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 "Contingent Deferred Sales Charge," 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
 
                                       32
<PAGE>
Exchange Privilege, the Transfer Agent acts as agent for the Distributor and for
the  shareholder's selected  broker-dealer, if any,  in the  performance of such
functions. The Transfer Agent shall be liable for its own negligence and not for
the default or negligence  of its correspondents or  for losses in transit.  The
Fund  shall not be liable  for any default or  negligence of the Transfer Agent,
the Distributor or any selected broker-dealer.
 
    The Distributor and any selected broker-dealer have authorized and appointed
the Transfer Agent to act as their  agent in connection with the application  of
proceeds of any redemption of Fund shares to the purchase of shares of any other
fund  and the general administration of the Exchange Privilege. No commission or
discounts will be paid to the Distributor or any selected broker-broker 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 is $5,000  for
Dean  Witter Liquid  Asset Fund Inc.,  Dean Witter Tax-Free  Daily Income Trust,
Dean Witter California  Tax-Free Daily  Income Trust  and Dean  Witter New  York
Municipal  Money Market  Trust, although those  funds may,  at their discretion,
accept initial investments of as low  as $1,000. The minimum initial  investment
is  $10,000 for  Dean Witter Short-Term  U.S Treasury Trust,  although that fund
may, at  its discretion,  accept initial  purchases  of as  low as  $5,000.  The
minimum  initial investment  is $5,000 for  Dean Witter Special  Value Fund. The
minimum initial  investment  for all  other  Dean  Witter Funds  for  which  the
Exchange Privilege is available is $1,000.) Upon exchange into an Exchange Fund,
the  shares of that  fund will be  held in a  special Exchange Privilege Account
separately from accounts of  those shareholders who  have acquired their  shares
directly  from that  fund. As a  result, certain services  normally available to
shareholders of those funds,  including the check writing  feature, will not  be
available for funds held in that account.
    
 
    The  Fund and each  of the other Dean  Witter Funds may  limit the number of
times this  Exchange  Privilege  may  be exercised  by  any  investor  within  a
specified  period of  time. Also,  the Exchange  Privilege may  be terminated or
revised at any time by  the Fund and/or any of  the Dean Witter Funds for  which
shares  of the Fund have been exchanged, upon  such notice as may be required by
applicable  regulatory  agencies  (presently  sixty  days'  prior  written   for
termination  or  material revision),  provided  that six  months'  prior written
notice of termination will be  given to the shareholders  who hold shares of  an
Exchange  Fund pursuant to the Exchange Privilege, and provided further that the
Exchange Privilege may  be terminated  or materially revised  without notice  at
times  (a) when the New  York Stock Exchange is  closed for other than customary
weekends and holidays, (b) when trading on that Exchange is restricted, (c) when
an emergency exists  as a result  of which  disposal by the  Fund of  securities
owned  by it is not  reasonably practicable or it  is not reasonably practicable
for the Fund fairly  to determine the  value of its net  assets, (d) during  any
other  period when  the Securities and  Exchange Commission by  order so permits
(provided that applicable rules and  regulations of the Securities and  Exchange
Commission  shall govern as to  whether the conditions prescribed  in (b) or (c)
exist) or (e)  if the  Fund would  be unable  to invest  amounts effectively  in
accordance with its investment objective, policies and restrictions.
 
    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.  As stated in the Prospectus, shares of the Fund can be redeemed
for  cash at any time at the net asset value per share next determined; however,
such redemption  proceeds  may  be  reduced by  the  amount  of  any  applicable
contingent  deferred  sales  charges  (see  below).  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
 
                                       33
<PAGE>
Agent,  which will redeem the shares at their net asset value next computed (see
"Purchase of Fund Shares" in the Prospectus) after it receives the request,  and
certificate,  if any, in good order.  Any redemption request received after such
computation will be redeemed  at the next determined  net asset value. The  term
"good  order"  means  that  the  share  certificate,  if  any,  and  request for
redemption are properly signed, accompanied by any documentation required by the
Transfer Agent, and bear signature guarantees  when required by the Fund or  the
Transfer  Agent. If redemption is requested by a corporation, partnership, trust
or fiduciary, the Transfer Agent may require that written evidence of  authority
acceptable to the Transfer Agent be submitted before such request is accepted.
 
    Whether  certificates are held  by the shareholder  or shares are  held in a
shareholder's account, if the proceeds are to  be paid to any person other  than
the record owner, or if the proceeds are to be paid to a corporation (other than
the Distributor or a selected broker-dealer for the account of the shareholder),
partnership,  trust or fiduciary, or sent to the shareholder at an address other
than the  registered  address, 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.
 
    CONTINGENT DEFERRED SALES CHARGE.  As stated in the Prospectus, a contingent
deferred sales charge ("CDSC") will be imposed on any redemption by an  investor
if  after such redemption the current value of the investor's shares of the Fund
is less  than the  dollar amount  of all  payments by  the shareholder  for  the
purchase of Fund shares during the preceding six 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
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 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 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  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  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 Fund  shares until  the time  of
redemption of such shares. For purposes of
 
                                       34
<PAGE>
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:

Sixth........................................                1.0%
Seventh and thereafter.......................                None
</TABLE>
 
    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 period. This will result in  any such CDSC being imposed at
the  lowest  possible  rate.  Accordingly,  shareholders  may  redeem,   without
incurring  any CDSC,  amounts equal to  any net  increase in the  value of their
shares above the  amount of  their purchase payments  made within  the past  six
years  and amounts equal to the current  value of shares purchased more than six
years prior  to the  redemption  and shares  purchased through  reinvestment  of
dividends  or distributions  or 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.  The CDSC will  be
imposed, in accordance with the table shown above, on any redemptions within six
years of purchase which are in excess of these amounts and which redemptions are
not  (a)  requested  within  one  year  of  death  or  initial  determination of
disability  of  a  shareholder,  or   (b)  made  pursuant  to  certain   taxable
distributions  from retirement plans or retirement accounts, as described in the
Prospectus.
 
    PAYMENT FOR SHARES REDEEMED OR REPURCHASED.  As discussed in the Prospectus,
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. 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  (including  a certified  or  bank  cashier's
check),  payment  of redemption  proceeds may  be delayed  for the  minimum time
needed to verify that the check used  for investment has been honored (not  more
than  fifteen days  from the  time of  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 accounts.
 
    TRANSFERS OF SHARES.   In  the event a  shareholder requests  a transfer  of
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 contingent  deferred sales charge or  free of such charge
(and with regard to the  length of time shares subject  to the charge have  been
held),  any transfer involving less than all of the shares in an account will be
made on  a  pro-rata  basis  (that  is,  by  transferring  shares  in  the  same
 
                                       35
<PAGE>
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 contingent  deferred sales charge 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 thirty days after the date of
redemption or repurchase, reinstate any portion  or all of the proceeds of  such
redemption  or repurchase  in shares  of the  Fund at  the net  asset value next
determined after  the reinstatement  request, together  with such  proceeds,  is
received by the Transfer Agent.
 
    Exercise  of the reinstatement privilege will  not affect the federal income
tax treatment of any gain or loss realized upon 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  the  amount  of  such
undistributed gains in  determining their  taxable income  and will  be able  to
claim  their share of the tax paid by the Fund as a credit against their federal
income tax.
 
    Because the Fund intends to distribute all of its net investment income  and
capital  gains to shareholders and otherwise  continue to qualify as a regulated
investment company under Subchapter  M of the Internal  Revenue Code, it is  not
expected  that  the  Fund  will  be required  to  pay  any  federal  income tax.
Shareholders will normally have to pay federal income taxes, and any  applicable
state and/or local income taxes, on the dividends and distributions they receive
from  the Fund. Such  dividends and distributions,  to the extent  that they are
derived from net investment income or  short-term capital gains, are taxable  to
the  shareholder  as  ordinary  income  regardless  of  whether  the shareholder
receives such payments in additional shares  or in cash. Any dividends  declared
in  the last quarter of  any calendar year which are  paid in the following year
prior to February  1 will be  deemed received  by the shareholder  in the  prior
year.
 
    Gains  or losses on  the sales of  securities by the  Fund will generally 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.
 
    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.
 
    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.
 
    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
 
                                       36
<PAGE>
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 will 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.
 
    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  long-term capital  gains, such
payment or  distribution  would  be  in  part  a  return  of  the  shareholder's
investment  to the  extent of such  reduction below the  shareholder's cost, but
nonetheless would be  fully taxable at  either ordinary or  capital gain  rates.
Therefore,  an investor should consider the  tax implications of purchasing Fund
shares immediately prior to a dividend or distribution record date.
 
    OPTIONS AND FUTURES.  Exchange-traded  futures contracts, listed options  on
futures   contracts  and  listed  options  on  U.S.  Government  securities  are
classified as "Section 1256" contracts under the Code. The character of gain  or
loss  resulting from  the sale,  disposition, closing  out, expiration  or other
termination of Section 1256 contracts is generally treated as long-term  capital
gain  or loss to the extent of 60 percent thereof and short-term capital gain or
loss to  the extent  of 40  percent  thereof. Section  1256 contracts  are  also
required  to  be marked-to-market  at the  end  of the  Fund's fiscal  year, for
purpose of Federal  income tax  calculations. These  rules may  be different  if
these transactions represent straddles for tax purposes.
 
    Over-the-counter  options are not  classified as Section  1256 contracts and
are not subject to the mark-to-market  or 60 percent-40 percent taxation  rules.
When  call options written, or put options purchased, by the Fund are exercised,
the gain or  loss realized  on the  sales of  the underlying  securities may  be
either  short-term  or  long-term,  depending upon  the  holding  period  of the
securities. In determining the  amount of gain or  loss, the sales proceeds  are
reduced  by  the premium  paid  for over-the-counter  puts  or increased  by the
premium received for over-the-counter calls.
 
    If the Fund holds a  U.S. Government security which  is offset by a  Section
1256  contract, the Fund would be deemed to hold a "mixed straddle" position, as
such is defined in the Code. The  Fund may elect to identify its mixed  straddle
positions  and thereby  avoid the application  of certain rules  which could, in
certain  circumstances,  cause  deferral  or  disallowance  of  losses,   change
long-term  capital  gains into  short-term gains,  or change  short-term capital
losses into long-term capital losses.
 
    Whether the portfolio  security constituting  part of  the identified  mixed
straddle  is deemed to have been held for less than three months for purposes of
determining qualification of the Fund as a regulated investment company will  be
determined  generally  by the  actual holding  period  of the  security, without
regard to the recognition of gain or loss upon entering into the mixed straddle.
This recognition of unrealized gain or loss will be taken into account, however,
in  determining  the  amount  of  income  available  for  the  Fund's  quarterly
distributions,  and  can result  in  an amount  which  is greater  or  less than
 
                                       37
<PAGE>
the Fund's net  realized gains being  available for distribution.  If an  amount
which  is less than the Fund's net realized gains is available for distribution,
the Fund may elect to distribute more than such available amount, up to the full
amount of such net realized gains. Such a distribution may, in part,  constitute
a return of capital to the shareholders.
 
    If  the Fund does not elect to  identify a mixed straddle, no recognition of
gain or loss  on the  U.S. Government securities  in the  Fund's portfolio  will
result  when the mixed straddle is entered into. However, any losses realized on
the straddle  will be  governed by  a number  of tax  rules which  might,  under
certain  circumstances, defer or disallow the losses in whole or in part, change
long-term  gains  into  short-term  gains,  or  change  short-term  losses  into
long-term  losses. A deferral or disallowance  of recognition of a realized loss
may result in an amount being  available for the Fund's quarterly  distributions
which is greater than the Fund's net realized gains.
 
    After  the  end  of  the  calendar  year,  shareholders  will  be  sent full
information on their dividends and capital gains distributions for tax purposes,
including information as to the portion taxable as ordinary income, the  portion
taxable  as long-term  capital gains  and any  portion treated  as a non-taxable
return of capital. Any such return of capital will reduce the shareholders'  tax
basis  in  their  shares.  To  avoid  being  subject  to  a  31%  federal backup
withholding tax  on  taxable  dividends, capital  gains  distributions  and  the
proceeds  of redemptions and  repurchases, shareholders' taxpayer identification
numbers must be furnished and certified as to their accuracy.
 
    Shareholders are urged to consult their attorneys or tax advisers  regarding
specific questions as to federal, state or local taxes.
 
PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
 
   
    As  discussed in the  Prospectus, from time  to time the  Fund may quote its
"yield" and/or its "total return" in advertisements and sales literature.  Yield
is  calculated for any 30-day  period as follows: the  amount of interest and/or
dividend income  for each  security in  the Fund's  portfolio is  determined  in
accordance  with  regulatory requirements;  the total  for the  entire portfolio
constitutes the Fund's gross income for the period. Expenses accrued during  the
period are subtracted to arrive at "net investment income". The resulting amount
is  divided by the product of  the net asset value per  share on the last day of
the period multiplied by  the average number of  Fund shares outstanding  during
the period that were entitled to dividends. This amount is added to 1 and raised
to  the sixth power. 1 is then subtracted  from the result and the difference is
multiplied by 2 to arrive at the  annualized yield. For the 30-day period  ended
October 31, 1996, the Fund's yield, calculated pursuant to the formula described
above, was 5.92%.
    
 
   
    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 contingent deferred sales charge  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
the  Fund for the fiscal  year ended October 31, 1996,  for the five years ended
October 31,  1996  and for  the  period from  March  31, 1987  (commencement  of
operations) through October 31, 1996 were -1.08%, 6.06% and 7.31%, respectively.
    
 
    In  addition to the foregoing, the Fund  may advertise its total return 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 the  contingent deferred  sales charge which,  if reflected,  would
reduce  the performance quoted. For example,  the average annual total return of
the Fund may be calculated in
 
                                       38
<PAGE>
   
the manner described above, but without deduction for any applicable  contingent
deferred  sales  charge. Based  on this  calculation,  the average  annual total
returns of the Fund  for the fiscal  year ended October 31,  1996, for the  five
years  ended October  31, 1996 and  for the  period from March  31, 1987 through
October 31, 1996 were 3.79%, 6.37% and 7.31%, respectively.
    
 
   
    In addition, the Fund may compute  its aggregate total return for  specified
periods  by determining the  aggregate percentage rate which  will result in the
ending value of a  hypothetical $1,000 investment made  at the beginning of  the
period.  For the purpose of  this calculation, it is  assumed that all dividends
and distributions  are reinvested.  The formula  for computing  aggregate  total
return  involves a percentage obtained by dividing the ending value (without the
reduction for  any  contingent deferred  sales  charge) by  the  initial  $1,000
investment   and  subtracting  1  from  the   result.  Based  on  the  foregoing
calculation, the Fund's  total returns  for the  fiscal year  ended October  31,
1996,  for the five years  ended October 31, 1996 and  for the period from March
31, 1987 through October 31, 1996 were 3.79%, 36.17% and 96.61%, respectively.
    
 
   
    The Fund  may  also advertise  the  growth of  hypothetical  investments  of
$10,000,  $50,000 and $100,000 in  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 $10,000, $50,000
or $100,000, as the case may be. Investments of $10,000, $50,000 and $100,000 in
the Fund  at  inception would  have  grown  to $19,661,  $98,305  and  $196,610,
respectively, at October 31, 1996.
    
 
    The  Fund  may advertise,  from time  to time,  its performance  relative to
certain performance rankings and indexes compiled by independent organizations.
 
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, except for Messrs. Bozic, Purcell and Schroeder, have
been elected by the shareholders of the Fund, most recently at a Special Meeting
of Shareholders held on January 12,  1993. Messrs. Bozic, Purcell and  Schroeder
were  elected by the other  Trustees of the Fund on  April 8, 1994. 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  or shorten their own terms or make
their terms of  unlimited duration  and appoint their  own successors,  provided
that  always  at  least a  majority  of the  Trustees  has been  elected  by the
shareholders of  the Fund.  Under  certain circumstances,  the Trustees  may  be
removed  by action of the Trustees. The  shareholders also have the right, under
certain circumstances, to remove the Trustees. The voting rights of shareholders
are not cumulative, so that holders of more than 50 percent of the shares voting
can, if they choose, elect all Trustees being selected, while the holders of the
remaining shares would be unable to elect any Trustees.
 
   
    The Declaration of Trust 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 presently  authorized
any such additional series or classes of shares.
    
 
    The Declaration of Trust further 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 duties. It also provides that all third persons shall look solely to  the
Fund    property   for   satisfaction   of    claims   arising   in   connection
 
                                       39

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 liability 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 or
the Trustees.

DEAN WITTER FEDERAL SECURITIES TRUST
REPORT OF INDEPENDENT ACCOUNTANTS
 
TO THE SHAREHOLDERS AND TRUSTEES
OF DEAN WITTER FEDERAL SECURITIES TRUST
 
In our opinion, the accompanying statement of assets and liabilities, including
the portfolio of investments, and the related statements of operations and of
changes in net assets and the financial highlights present fairly, in all
material respects, the financial position of Dean Witter Federal Securities
Trust (the "Fund") at October 31, 1996, 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 nine years in the
period then ended and for the period March 31, 1987 (commencement of operations)
through October 31, 1987, in conformity with generally accepted accounting
principles. These financial statements and financial highlights (hereafter
referred to as "financial statements") are the responsibility of the Fund's
management; our responsibility is to express an opinion on these financial
statements based on our audits. We conducted our audits of these financial
statements in accordance with generally accepted auditing standards which
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits, which included
confirmation of securities at October 31, 1996 by correspondence with the
custodian and brokers, provide a reasonable basis for the opinion expressed
above.

DEAN WITTER FEDERAL SECURITIES TRUST
NOTES TO FINANCIAL STATEMENTS OCTOBER 31, 1996
 
1. ORGANIZATION AND ACCOUNTING POLICIES
 
Dean Witter Federal Securities Trust (the "Fund") is registered under the
Investment Company Act of 1940, as amended (the "Act"), as a diversified,
open-end management investment company. The Fund's investment objective is to
earn a high level of current income. The Fund commenced operations on March 31,
1987.
 
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) all portfolio securities for which
over-the-counter market quotations are readily available are valued at the
latest available bid price prior to the time of valuation; (2) listed options
are valued at the latest sale price on the exchange on which they are listed
unless no sales of such options have taken place that day, in which case they
will be valued at the mean between their latest bid and asked price; (3) futures
contracts are valued at the latest sale price as of the close of the commodities
exchange on which they trade unless the Trustees determine that such price does
not reflect their market value, in which case they will be valued at fair value
as determined by the Trustees; (4) when market quotations are not readily
available, including circumstances under which it is determined by the
Investment Manager that the sale or bid prices are not reflective of a
securities 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); and (5) short-term debt securities having a
maturity date of more than sixty days at the time of purchase are valued on a
mark-to-market basis until sixty days prior to maturity and thereafter at
amortized cost based on their value on the 61st day. Short-term debt securities
having a maturity date of sixty days or less at the time of purchase are valued
at amortized cost.
 
B. ACCOUNTING FOR INVESTMENTS -- Security transactions are accounted for on the
trade date (date the order to buy or sell is executed). Realized gains and
losses on security transactions are determined by the identified cost method.
Discounts are accreted over the life of the respective securities. Interest
income is accrued daily.
 
C. OPTIONS AND FUTURES -- (1) Written options on debt obligations: When the Fund
writes a call or put option, an amount equal to the premium received is included
in the Fund's Statement of Assets and
 
                                       48
<PAGE>
DEAN WITTER FEDERAL SECURITIES TRUST
NOTES TO FINANCIAL STATEMENTS OCTOBER 31, 1996, CONTINUED
 
Liabilities as a liability which is subsequently marked-to-market to reflect the
current market value. If a written option either expires or the Fund enters into
a closing purchase transaction, the Fund realizes a gain or loss without regard
to any unrealized gain or loss on the underlying security and the liability
related to such option is extinguished. If a written call option is exercised,
the Fund realizes a gain or loss from the sale of the underlying security and
the proceeds from such sale are increased by the premium originally received. If
a written put option is exercised, the amount of the premium originally received
reduces the cost of the security which the Fund purchases upon exercise of the
option; (2) Purchased options on debt obligations: When the Fund purchases a
call or put option, the premium paid is recorded as an investment which is
subsequently marked-to-market to reflect the current market value. If a
purchased option expires, the Fund will realize a loss to the extent of the
premium paid. If the Fund enters into a closing sale transaction, a gain or loss
is realized for the difference between the proceeds from the sale and the cost
of the option. If a put option is exercised, the cost of the security sold upon
exercise will be increased by the premium originally paid. If a call option is
exercised, the cost of the security purchased upon exercise will be increased by
the premium originally paid; (3) Options on futures contracts: The Fund is
required to deposit U.S. Government securities or other liquid portfolio
securities as "initial margin" and "variation margin" with respect to written
call and put options on futures contracts. If a written option expires, the Fund
realizes a gain. If a written call or put option is exercised, the premium
received will decrease or increase the unrealized loss or gain on the futures
contract. If the Fund enters into a closing purchase transaction, the Fund
realizes a gain or loss without regard to any unrealized gain or loss on the
underlying futures contract and the liability related to such option is
extinguished; (4) Futures contracts: A futures contract is an agreement between
two parties to buy and sell financial instruments at a set price on a future
date. Upon entering into such a contract, the Fund is required to pledge to the
broker cash or U.S. Government securities equal to the minimum initial margin
requirements of the applicable futures exchange. Pursuant to the contract, the
Fund agrees to receive from or pay to the broker an amount of cash equal to the
daily fluctuation in the value of the contract. Such receipts or payments known
as variation margin are recorded by the Fund as unrealized gains or losses. Upon
closing of the contract, the Fund realizes a gain or loss equal to the
difference between the value of the contract at the time it was opened and the
value at the time it was closed.
 
D. FEDERAL INCOME TAX STATUS -- It is the Fund's policy to comply with the
requirements of the Internal Revenue Code applicable to regulated investment
companies and to distribute all of its taxable income to its shareholders.
Accordingly, no federal income tax provision is required.

DEAN WITTER FEDERAL SECURITIES TRUST
NOTES TO FINANCIAL STATEMENTS OCTOBER 31, 1996, CONTINUED
 
E. DIVIDENDS AND DISTRIBUTIONS TO SHAREHOLDERS -- The Fund records dividends and
distributions to its shareholders on the ex-dividend date. The amount of
dividends and distributions from net investment income and net realized capital
gains are determined in accordance with federal income tax regulations which may
differ from generally accepted accounting principles. These "book/tax"
differences are either considered temporary or permanent in nature. To the
extent these differences are permanent in nature, such amounts are reclassified
within the capital accounts based on their federal tax-basis treatment;
temporary differences do not require reclassification. Dividends and
distributions which exceed net investment income and net realized capital gains
for financial reporting purposes but not for tax purposes are reported as
dividends in excess of net investment income or distributions in excess of net
realized capital gains. To the extent they exceed net investment income and net
realized capital gains for tax purposes, they are reported as distributions of
paid-in-capital.
 
2. INVESTMENT MANAGEMENT AGREEMENT
 
Pursuant to an Investment Management Agreement with Dean Witter InterCapital
Inc. (the "Investment Manager"), the Fund pays the Investment Manager a
management fee, accrued daily and payable monthly, by applying the following
annual rates to the Fund's net assets determined at the close of each business
day: 0.55% to the portion of daily net assets not exceeding $1 billion; 0.525%
to the portion of daily net assets exceeding $1 billion but not exceeding $1.5
billion; 0.50% to the portion of daily net assets exceeding $1.5 billion but not
exceeding $2 billion; 0.475% to the portion of daily net assets exceeding $2
billion but not exceeding $2.5 billion; 0.45% to the portion of daily net assets
exceeding $2.5 billion but not exceeding $5 billion; 0.425% to the portion of
daily net assets exceeding $5 billion but not exceeding $7.5 billion; 0.40% to
the portion of daily net assets exceeding $7.5 billion but not exceeding $10
billion; 0.375% to the portion of daily net assets exceeding $10 billion but not
exceeding $12.5 billion; and 0.35% to the portion of daily net assets exceeding
$12.5 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 pursuant
to which the Fund pays the Distributor compensation, accrued daily and payable
monthly, at an annual rate of 0.85% of the lesser of: (a) the average daily
aggregate gross sales of the Fund's shares since the Fund's inception (not
including reinvestment of dividend or capital gain distributions) less the
average daily aggregate net asset value of the Fund's shares redeemed since the
Fund's inception upon which a contingent deferred sales charge has been imposed
or upon which such charge has been waived; or (b) the Fund's average daily net
assets. Amounts paid under the Plan are paid to the Distributor to compensate it
for the services provided and the expenses borne by it and others in the
distribution of the Fund's shares, including the payment of commissions for
sales of the Fund's shares and incentive compensation to, and expenses of, the
account executives of Dean Witter Reynolds Inc. ("DWR"), an affiliate of the
Investment Manager and Distributor, and other employees or selected
broker-dealers who engage in or support distribution of the Fund's 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 be compensated under the Plan for
its opportunity costs in advancing such amounts which compensation would be in
the form of a carrying charge on any unreimbursed expenses incurred by the
Distributor.
 
Provided that the Plan continues in effect, any cumulative expenses incurred by
the Distributor but not yet recovered, may be recovered through future
distribution fees from the Fund and contingent deferred sales charges from the
Fund's shareholders.
 
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 the 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
$27,489,031 at October 31, 1996.
 
The Distributor has informed the Fund that for the year ended October 31, 1996,
it received approximately $641,000 in contingent deferred sales charges from
certain redemptions of the Fund's shares.

defer approximately $10,449,000 of realized losses on certain closed options and
futures contracts.
 
At October 31, 1996, the Fund had temporary book/tax differences primarily
attributable to capital loss deferrals on straddles and permanent book/tax
differences attributable to an expired capital loss carryover. To reflect
reclassifications arising from permanent book/tax differences for the year ended
October 31, 1996, paid-in-capital was charged and accumulated net realized loss
was credited $27,139,691.
 
7. PURPOSES OF AND RISKS RELATING TO CERTAIN FINANCIAL INSTRUMENTS
 
To hedge against adverse interest rate and market risks on portfolio positions
or anticipated positions in U.S. Government securities, or in the case of
written options, to close out long or short positions in futures contracts, the
Fund may enter into written options on interest rate futures and interest rate
futures contracts ("derivative instruments").
 
These derivative instruments involve elements of market risk in excess of the
amount reflected in the Statement of Assets and Liabilities. The Fund bears the
risk of an unfavorable change in the value of the underlying securities or
currencies.
 
At October 31, 1996, the Fund had outstanding written options on interest rate
futures and interest rate futures used to manage interest rate and market
exposure on portfolio positions or anticipated positions in U.S. Government
securities.

RATINGS OF CORPORATE DEBT INSTRUMENTS
                                      BONDS
 
    The  four highest ratings of Moody's Investors Service, Inc. ("Moody's") for
corporate bonds are Aaa, Aa, A and  Baa, all of which are considered  investment
grade.  Bonds rated Aaa are judged to be of the "best quality". The rating of Aa
is assigned to bonds  which are of  "high quality by all  standards", but as  to
which  margins  of  protection or  other  elements make  long-term  risks appear
somewhat larger than Aaa rated bonds. The  Aaa and Aa rated bonds comprise  what
are  generally known as "high  grade bonds". Bonds which  are rated A by Moody's
possess many favorable  investment attributes and  are considered "upper  medium
grade  obligations". Bonds rated Baa  are considered "medium grade" obligations.
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.  Moody's  applies  numerical
modifiers,  1, 2,  and 3, in  each rating  classification for Aa  and below. The
modifier 1 indicates that the security ranks in the higher end of its  category;
the  modifier 2 indicates a mid-range ranking; and the modifier 3 indicates that
the issue ranks  in the lower  end of  its category. The  foregoing ratings  are
sometimes  presented in  parentheses preceded with  a "con"  indicating that the
bonds are rated conditionally.  Bonds, the security for  which depends upon  the
completion  of  some  act  or  the  fulfillment  of  some  condition,  are rated
conditionally. These  are  bonds  secured  by (a)  earnings  of  projects  under
construction,  (b) earnings  of projects when  facilities are  completed, or (c)
payments to which  some other  limiting condition  attaches. Such  parenthetical
rating  denotes the probable  credit stature upon  completion of construction or
elimination of the basis of the condition.
 
    The four  highest ratings  of  Standard &  Poor's Corporation  ("Standard  &
Poor's")  for  bonds  are  AAA, AA,  A  and  BBB, all  of  which  are considered
investment grade. Bonds rated AAA bear the highest rating assigned by Standard &
Poor's to  a debt  obligation,  and the  rating  indicates an  extremely  strong
capacity  to pay interest  and repay principal.  Bonds rated AA  also qualify as
high-quality debt obligations. Capacity to  pay interest and repay principal  is
very  strong, and in the majority of  instances they differ from AAA issues only
in small degree. Bonds rated  A have 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.  The BBB rating, which is  the
lowest  "investment grade"  security rating by  Standard &  Poor's, indicates an
adequate capacity to  repay principal  and pay interest.  Whereas they  normally
exhibit  adequate protection parameters, adverse economic conditions or changing
circumstances are more likely  to lead to a  weakened capacity to pay  principal
and  interest for bonds in  this category than for bonds  in the A category. The
ratings of AA and below may be modified by the addition of a plus or minus  sign
to  show relative  standing within  the major  rating categories.  The foregoing
ratings are  sometimes followed  by a  "p" which  indicates that  the rating  is
provisional.  A  provisional rating  assumes  the successful  completion  of the
project being financed by  the bonds being rated  and indicates that payment  of
debt  service requirements is largely or  entirely dependent upon the successful
and timely completion  of the  project. This rating,  however, while  addressing
credit  quality subsequent to completion of the project, makes no comment on the
likelihood or risk of default upon failure of such completion.
 
                                COMMERCIAL PAPER
 
    Moody's Commercial Paper ratings are opinions  of the ability of issuers  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, Highest Quality;  Prime-2, Higher Quality; and  Prime-3,
High Quality.
 
    Standard  & Poor's  commercial paper rating  is a current  assessment of the
likelihood of timely payment of debt having an original maturity of no more than
365 days. The commercial paper rating is
 
                                       55
<PAGE>
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  four categories, ranging from  "A" for the highest
quality obligations  to  "D" for  the  lowest.  Issues assigned  A  ratings  are
regarded  as having  the greatest  capacity for  timely payment.  Issues in this
category are further refined with the designations  1, 2, and 3 to indicate  the
relative  degree of safety. The "A-1+"  and "A-1" designations indicate that the
degree of safety regarding timely payment is very strong.

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, 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


                                        2

<PAGE>

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

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

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

                     DEAN WITTER FEDERAL SECURITIES TRUST 
                 AMENDED AND RESTATED AS OF OCTOBER 25, 1996 

                                  ARTICLE I 

                                 DEFINITIONS 

   The terms "COMMISSION", "DECLARATION", "DISTRIBUTOR", "INVESTMENT 
ADVISER", "MAJORITY SHAREHOLDER VOTE", "1940 ACT", "SHAREHOLDER", "SHARES", 
"TRANSFER AGENT", "TRUST", "TRUST PROPERTY", and "TRUSTEES" have the 
respective meanings given them in the Declaration of Trust of Dean Witter 
Federal Securities Trust dated November 20, 1986, as amended from time to 
time. 

                                  ARTICLE II
 
                                   OFFICES 

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

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

                                 ARTICLE III
 
                            SHAREHOLDERS' MEETINGS 

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

   SECTION 3.2. MEETINGS. Meetings of Shareholders of the Trust shall be held 
whenever called by the Trustees or the President of the Trust and whenever 
election of a Trustee or Trustees by Shareholders is required by the 
provisions of Section 16(a) of the 1940 Act, for that purpose. Meetings of 
Shareholders shall also be called by the Secretary upon the written request 
of the holders of Shares entitled to vote not less than twenty-five percent 
(25%) of all the votes entitled to be cast at such meeting. Such request 
shall state the purpose or purposes of such meeting and the matters proposed 
to be acted on thereat. The Secretary shall inform such Shareholders of the 
reasonable estimated cost of preparing and mailing such notice of the 
meeting, and upon payment to the Trust of such costs, the Secretary shall 
give notice stating the purpose or purposes of the meeting to all entitled to 
vote at such meeting. No meeting need be called upon the request of the 
holders of Shares entitled to cast less than a majority of all votes entitled 
to be cast at such meeting, to consider any matter which is substantially the 
same as a matter voted upon at any meeting of Shareholders held during the 
preceding twelve months. 

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

                                       1

<PAGE>

   SECTION 3.4. QUORUM AND ADJOURNMENT OF MEETINGS. Except as otherwise 
provided by law, by the Declaration or by these By-Laws, at all meetings of 
Shareholders the holders of a majority of the Shares issued and outstanding 
and entitled to vote thereat, present in person or represented by proxy, 
shall be requisite and shall constitute a quorum for the transaction of 
business. In the absence of a quorum, the Shareholders present or represented 
by proxy and entitled to vote thereat shall have power to adjourn the meeting 
from time to time. Any adjourned meeting may be held as adjourned without 
further notice. At any adjourned meeting at which a quorum shall be present, 
any business may be transacted as if the meeting had been held as originally 
called. 

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

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

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

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

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

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

                                  ARTICLE IV 

                                   TRUSTEES 

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

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

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

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

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

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

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

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

                                       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--

          (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

those of President and any Vice President, may be held by the same person,

than one capacity. The executive officers of the Trust shall be elected 
annually by the Trustees and each executive officer so elected shall hold

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.

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

time by the Trustees or the President, shall, in the absence or disability of 
the President, exercise the powers and perform the duties of the President, 
and he or they shall perform such other duties as the Trustees or the 
President may from time to time prescribe. 

   SECTION 6.9. THE ASSISTANT VICE PRESIDENTS. The Assistant Vice President, 
or, if there be more than one, the Assistant Vice Presidents, shall perform

the Trustees or the President. 

   SECTION 6.10. THE SECRETARY. The Secretary shall attend all meetings of 
the Trustees and all meetings of the Shareholders and record all the

to be kept for that purpose, and shall perform like duties for the standing

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 
the Trustees or the President, shall, in the absence or disability of the

President may from time to time prescribe. 

   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 
require it, an account of his transactions as Treasurer and of the financial 
condition of the Trust; and he shall perform such other duties as the 
Trustees, or the President, may from time to time prescribe. 

   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 
other officer or officers or to any Trustee or Trustees. 

                                 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 
Trustees may determine, in cash, in securities or other property, or in 
Shares, from any sources permitted by law, all as the Trustees shall from 
time to time determine. 

                                       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 
    the same upon written or electronically transmitted order; 

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

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

                                       8

<PAGE>

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

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

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

                                  ARTICLE X 

                               WAIVER OF NOTICE 

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

                                  ARTICLE XI
 
                                MISCELLANEOUS

Trust may be kept outside the Commonwealth of Massachusetts at such place or 
places as the Trustees may from time to time determine, except as otherwise 
required by law. 

   SECTION 11.2. RECORD DATE. The Trustees may fix in advance a date as the 
record date for the purpose of determining 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 
taken. In lieu of fixing a record date the Trustees may provide that the 
transfer books shall be closed for a stated period but not to exceed, in any 
case, twenty (20) days. If the transfer books are closed for the purpose of 
determining Shareholders entitled to notice of a vote at a meeting of 
Shareholders, such books shall be closed for at least ten (10) days 
immediately preceding 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
<PAGE>

   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 Federal Securities 
Trust, dated November 20, 1986, a copy of which, together with all amendments 
thereto, is on file in the office of the Secretary of the Commonwealth of 
Massachusetts, provides that the name Dean Witter Federal Securities Trust 
(formerly known as Dean Witter Government Securities Plus) refers to the 
Trustees under the Declaration collectively as Trustees, but not as 
individuals or personally; and no Trustee, Shareholder, officer, employee or 
agent of Dean Witter Federal Securities Trust shall be held to any personal 
liability, nor shall resort be had to their private property for the 
satisfaction of any obligation or claim or otherwise, in connection with the 
affairs of said Dean Witter Federal Securities Trust, but the Trust Estate 
only shall be liable.

                         AMENDMENT TO CUSTODY AGREEMENT

     Amendment made as of this 17th day of April, 1996 by and between Dean 
Witter Federal Securities Trust (the "Fund") and The Bank of New York (the 
"Custodian") to the Custody Agreement between the Fund and the Custodian 
dated September 20, 1991 (the "Custody Agreement"). The Custody Agreement is 
hereby amended as follows:

     Article XV Section 8 of the Custody Agreement shall be deleted and be
replaced by Section 8.(a), 8.(b) and 8.(c) as set forth below:

     "8.  (a)  The Custodian will use reasonable care with respect to its 
obligations under this Agreement and the safekeeping of Securities and moneys 
owned by the Fund. The Custodian shall indemnify the Fund against and save 
the Fund harmless from all liability, claims, losses and demands whatsoever, 
including attorneys' fees, howsoever arising or incurred as the result of the 
failure of a subcustodian which is a banking institution located in a foreign 
country and identified on Schedule A attached hereto and as amended from time 
to time upon mutual agreement of the parties (each, a "Subcustodian") to 
exercise reasonable care with respect to the safekeeping of such Securities 
and moneys to the same extent that the Custodian would be liable to the Fund 
if the Custodian were holding such securities and moneys in New York. In the 
event of any loss to the Fund by reason of the failure of the Custodian or a 
Subcustodian to utilize reasonable care, the Custodian shall be liable to the 
Fund only to the extent of the Fund's direct damages, to be determined based 
on the market value of the Securities and moneys which are the subject of the 
loss at the date of discovery of such loss and without reference to any 
special conditions or circumstances.

     8.   (b)  The Custodian shall not be liable for any loss which results from
(i) the general risk of investing, or (ii) investing or holding Securities and
moneys in a particular country including, but not limited to, losses resulting
from nationalization, expropriation or other governmental actions; regulation of
the banking or securities industry; currency restrictions, devaluations or
fluctuations; or market conditions which prevent the orderly execution of
securities transactions or affect the value of Securities or moneys.

     8.   (c)  Neither party shall be liable to the other for any loss due to
forces beyond its control including, but not limited to, strikes or work
stoppages, acts of war or terrorism, insurrection, revolution, nuclear fusion,
fission or radiation, or acts of God."

     IN WITNESS WHEREOF, the parties hereto have caused this Amendment to be
executed by their respective Officers, thereunto duly authorized and their
respective seals to be hereunto affixed, as of the day and year first above
written.
