                        HIGH INCOME SECURITIES
                        PROSPECTUS--MAY 23, 1996
 
- -------------------------------------------------------------------------------
 
DEAN  WITTER  HIGH INCOME  SECURITIES (THE  "FUND")  IS AN  OPEN-END DIVERSIFIED
MANAGEMENT INVESTMENT COMPANY WHOSE  PRIMARY INVESTMENT OBJECTIVE  IS TO EARN  A
HIGH  LEVEL OF  CURRENT INCOME.  AS A  SECONDARY OBJECTIVE,  THE FUND  WILL SEEK
CAPITAL APPRECIATION, BUT ONLY WHEN  CONSISTENT WITH ITS PRIMARY OBJECTIVE.  THE
FUND  SEEKS  HIGH  CURRENT  INCOME  BY  INVESTING  PRINCIPALLY  IN  FIXED-INCOME
SECURITIES WHICH  ARE  RATED  IN  THE LOWER  CATEGORIES  BY  ESTABLISHED  RATING
SERVICES  (BA OR  LOWER BY  MOODY'S INVESTORS  SERVICE, INC.  OR BB  OR LOWER BY
STANDARD &  POOR'S  CORPORATION)  OR  ARE  NON-RATED  SECURITIES  OF  COMPARABLE
QUALITY.
 
The  Fund invests predominantly in  lower-rated fixed-income securities commonly
known as  junk bonds  and investors  should carefully  consider the  risks  they
present,  including  the risk  of default.  Bonds  of this  type are  subject to
greater risks than higher-rated securities and are considered to be  speculative
with regard to the payment of interest and return of principal. Investors should
also  be cognizant of the fact that  such securities are not generally meant for
short-term investing and should assess  the risks associated with an  investment
in the Fund. (See "Risk Considerations.")
 
Shares  of  the  Fund are  continuously  offered  at net  asset  value. However,
redemptions and/or  repurchases  are  subject  in most  cases  to  a  contingent
deferred sales charge, scaled down from 4% to 1% of the amount redeemed, if made
within  five  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 distribution fee pursuant to a Rule 12b-1 Plan of Distribution  at
the  annual rate of 0.80%  of the lesser of the  (i) average daily aggregate net
sales or (ii)  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  reference.
Additional  information  about  the  Fund  is  contained  in  the  Statement  of
Additional Information,  dated May  23,  1996, which  has  been filed  with  the
Securities  and Exchange  Commission, and which  is available at  no charge upon
request of  the Fund  at the  address  or telephone  numbers listed  below.  The
Statement of Additional Information is incorporated herein by reference.

PROSPECTUS SUMMARY
- --------------------------------------------------------------------------------
 
<TABLE>
<S>             <C>
THE FUND        The  Fund is organized as a Trust, commonly known as a Massachusetts business trust, and
                is an  open-end  diversified  management investment  company  investing  principally  in
                lower-rated fixed-income securities (see page 5).
- -------------------------------------------------------------------------------------------------------
 
SHARES OFFERED  Shares of beneficial interest with $0.01 par value (see page 18).
- -------------------------------------------------------------------------------------------------------
 
OFFERING        At net asset value without sales charge (see page 11). Shares redeemed within five years
PRICE           of  purchase are subject to a contingent  deferred sales charge under most circumstances
                (see page 15).
- -------------------------------------------------------------------------------------------------------
 
MINIMUM         Minimum  initial   investment,  $1,000   ($100  if   the  account   is  opened   through
PURCHASE        EasyInvest-SM-); minimum subsequent investment, $100 (see page 11).
- -------------------------------------------------------------------------------------------------------
 
INVESTMENT      A  high level of current  income primarily; capital appreciation  is secondary (see page
OBJECTIVE       5).
- -------------------------------------------------------------------------------------------------------
 
INVESTMENT      Dean Witter InterCapital Inc., the Investment Manager of the Fund, and its  wholly-owned
MANAGER         subsidiary,  Dean Witter Services Company Inc.,  serve in various investment management,
                advisory, management and administrative capacities to ninety-eight investment  companies
                and  other portfolios with assets of approximately  $83.8 billion at April 30, 1996 (see
                page 5).
- -------------------------------------------------------------------------------------------------------
 
MANAGEMENT FEE  The Investment Manager receives  a monthly fee  at the annual rate  of 0.50% of  average
                daily  net assets.  The fee should  not be compared  with fees paid  by other investment
                companies without  also  considering  applicable  sales  loads  and  distribution  fees,
                including those noted below (see page 5).
- -------------------------------------------------------------------------------------------------------
 
DIVIDENDS AND   Income  dividends  are  declared  and  paid  monthly;  capital  gains,  if  any,  may be
CAPITAL GAINS   distributed at least annually. Dividends and distributions are automatically  reinvested
DISTRIBUTIONS   in  additional shares at net asset value  (without sales charge), unless the shareholder
                elects to receive cash (see page 17).
- -------------------------------------------------------------------------------------------------------
 
DISTRIBUTOR     Dean Witter Distributors  Inc. (the  "Distributor"). The Distributor  receives from  the
AND DISTRIBU-   Fund,  pursuant to a Rule  12b-1 Plan of Distribution,  a distribution fee accrued daily
TION FEE        and payable monthly  at the rate  of 0.80%  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 its sales-related  expenses. The Distributor also  receives the proceeds of  any
                contingent deferred sales charges (see pages 12 and 15).
- -------------------------------------------------------------------------------------------------------
 
REDEMPTION--    Shares  are  redeemable  by  the shareholder  at  net  asset value.  An  account  may be
CONTINGENT      involuntarily redeemed  if total  value of  the account  is less  than $100  or, if  the
DEFERRED SALES  account  was opened through  EasyInvest-SM-, if after twelve  months the shareholder has
CHARGE          invested less than  $1,000 in the  account. Although  no commission or  sales charge  is
                imposed  upon the purchase  of shares, a  contingent deferred sales  charge (scaled down
                from 4% 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 five  years preceding the  redemption.
                However,  there  is  no  charge  imposed  on  redemption  of  shares  purchased  through
                reinvestment of dividends or distributions (see pages 15-16).
- -------------------------------------------------------------------------------------------------------
 
RISKS           Compared with higher rated, lower yielding fixed-income securities, portfolio securities
                of the Fund may be subject to greater  risk of loss of income and principal and  greater
                risk  of increases and decreases in net asset value due to market fluctuations. The Fund
                may also purchase when-issued and delayed  delivery, when, as and if issued  securities,
                restricted  securities,  and zero  coupon securities,  rights and  warrants, convertible
                securities, foreign securities,  common stock  and adjustable rate  mortgages and  enter
                into  repurchase agreements, reverse repurchase agreements and dollar rolls, options and
                futures transactions  and forward  foreign  currency exchange  contracts, all  of  which
                involve  certain special  risks. Investors should  review the  investment objectives and
                policies of the Fund carefully and consider  their ability to assume the risks  involved
                in purchasing shares of the Fund (see pages 6-10).

THE FUND AND ITS MANAGEMENT
- --------------------------------------------------------------------------------
 
Dean Witter  High Income  Securities  (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 The
Commonwealth of Massachusetts on March 23, 1994.
 
    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 ninety-eight investment companies (the "Dean Witter
Funds"), thirty  of  which are  listed  on the  New  York Stock  Exchange,  with
combined assets of approximately $81.2 billion at April 30, 1996. The Investment
Manager  also  manages  portfolios  of  pension  plans,  other  institutions and
individuals which aggregated approximately $2.6 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
Board  of  Trustees  reviews  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
annual rate of 0.50% to the Fund's net assets determined as of the close of each
business day. Effective May 1,  1996, the Investment Manager's compensation  was
reduced  to 0.425% of  daily net assets  over $500 million.  For the fiscal year
ended March 31,  1996, the  Fund accrued  total compensation  to the  Investment
Manager  amounting to an  annual rate of  0.50% of the  Fund's average daily net
assets and the Fund's total expenses amounted to an annual rate of 1.49% of  the
Fund's average daily net assets.
 
INVESTMENT OBJECTIVES AND POLICIES
- --------------------------------------------------------------------------------
 
The  primary investment objective of the Fund is to earn a high level of current
income. As a secondary objective, the  Fund will seek capital appreciation,  but
only  when  consistent  with  its primary  objective.  Capital  appreciation may
result, for example,  from an improvement  in the credit  standing of an  issuer
whose  securities are held in the Fund's  portfolio or from a general decline in
interest rates, or a combination  of both. Conversely, capital depreciation  may
result,  for  example, from  a  lowered credit  standing  or a  general  rise in
interest rates,  or  a combination  of  both. There  is  no assurance  that  the
objectives will be achieved. The objectives are fundamental policies of the Fund
and  may not  be changed  without the approval  of the  Fund's shareholders. The
following policies may be  changed by the  Fund's Trustees, without  shareholder
approval.
 
    The  higher  yields  sought  by  the  Fund  are  generally  obtainable  from
securities rated in the lower categories by recognized rating services. The Fund
seeks high current income  by investing principally (at  least 65% of its  total
assets)  in  fixed-income  securities rated  Ba  or lower  by  Moody's Investors
Service, Inc.  ("Moody's"), or  BB or  lower by  Standard &  Poor's  Corporation
("Standard  &  Poor's"). Fixed-income  securities  rated Ba  or  BB or  lower by
Moody's and Standard &  Poor's, respectively, are  considered to be  speculative
investments.  Furthermore, the  Fund does  not have  any minimum  quality rating
standard for its investments. As such,  the Fund may invest in securities  rated
as  low as Caa, Ca or C by Moody's or  CCC, CC, C, CI or D by Standard & Poor's.
Fixed-income securities rated Caa or Ca by Moody's may already be in default  on
payment  of interest or principal, while bonds  rated C by Moody's, their lowest
bond rating,  can  be  regarded  as having  extremely  poor  prospects  of  ever
attaining  any real investment standing (the  Fund may purchase securities which
are in default  and which,  thereby, are  not paying  its fixed-income  security
holders  principal and/or interest).  Bonds rated D by  Standard & Poor's, their
lowest bond rating,  are in  payment default. For  a further  discussion of  the
characteristics  and  risks associated  with  high yield  securities,  see "Risk
Considerations" below. A description of  corporate bond ratings is contained  in
the Appendix.
 
    Non-rated securities will also be considered for investment by the Fund when
the  Investment Manager believes that the  financial condition of the issuers of
such securities,  or the  protection afforded  by the  terms of  the  securities

average maturity of the Fund's portfolio will be between five and ten years.
 
    Up to  35% of  the Fund's  total  assets may,  under normal  conditions,  be
invested  in  common  stocks; fixed-income  securities  convertible  into common
stocks; warrants  to  purchase  common  stocks;  investment  grade  fixed-income
securities;  U.S.  Government  securities  (including  zero  coupon securities);
mortgage-backed securities,  financial futures  contracts and  options  thereon;
index  options;  options  on  debt and  equity  securities;  private placements;
repurchase agreements; and  reverse repurchase agreements.  In addition, any  or
all  of the  above 35% of  total assets portion  of the Fund's  portfolio may be
comprised of securities issued by foreign issuers.
 
    Pending investment of proceeds from the sale of shares of the Fund or of its
portfolio securities or  at other times  when market conditions  dictate a  more
"defensive"  investment strategy,  the Fund  may invest  without limit  in money
market instruments, including commercial  paper of corporations organized  under
the   laws  of  any  state  or  political  subdivision  of  the  United  States,
certificates of deposit, bankers' acceptances and other obligations of  domestic
banks  or domestic  branches of foreign  banks, or foreign  branches of domestic
banks, in  each  case  having  total  assets  of  at  least  $500  million,  and
obligations  issued or  guaranteed by the  United States  Government, or foreign
governments or  their respective  instrumentalities or  agencies. The  yield  on
these  securities  will generally  tend  to be  lower  than the  yield  on other
securities to  be  purchased by  the  Fund. To  the  extent the  Fund  purchases
Eurodollar certificates of deposit issued by foreign branches of domestic United
States  banks, consideration will be given  to their domestic marketability, the
lower reserve requirements  normally mandated for  overseas banking  operations,
the  possible  impact of  interruptions in  the  flow of  international currency
transactions and economic developments which might adversely affect the  payment
of principal or interest.
 
    All  fixed-income securities are  subject to two types  of risks: the credit
risk and the interest rate risk. The  credit risk relates to the ability of  the
issuer  to  meet  interest or  principal  payments  or both  as  they  come due.
Generally, higher  yielding bonds  are subject  to a  credit risk  to a  greater
extent  than  higher  quality  bonds.  The  interest  rate  risk  refers  to the
fluctuations in  net asset  value of  any portfolio  of fixed-income  securities
resulting solely from the inverse relationship between price and yield of fixed-
income  securities; that is, when the general level of interest rates rises, the
prices of  outstanding  fixed-income  securities  generally  decline,  and  when
interest rates fall, prices generally rise.
 
    The  ratings of fixed-income securities by Moody's and Standard & Poor's are
a generally accepted barometer of credit risk. However, as the  creditworthiness
of  issuers of  lower-rated fixed-income  securities is  more problematical than
that of issuers of higher-rated fixed-income securities, the achievement of  the
Fund's  investment  objectives  will  be  more  dependent  upon  the  Investment
Manager's own  credit  analysis  than would  be  the  case with  a  mutual  fund
investing primarily in higher quality bonds. The Investment Manager will utilize
a   security's  credit   rating  as  simply   one  indication   of  an  issuer's
creditworthiness and will principally rely upon its own analysis of any security
currently held  by the  Fund or  potentially  purchasable by  the Fund  for  its
portfolio.
 
    In determining which securities to purchase or hold for the Fund's portfolio
and  in seeking to reduce credit and interest rate risks, the Investment Manager
will rely on  information from  various sources,  including: the  rating of  the
security;  research, analysis and  appraisals of brokers  and dealers, including
DWR; the views of the Fund's Trustees and others regarding economic developments
and interest rate trends; and the  Investment Manager's own analysis of  factors
it  deems relevant. The extent to which  the Investment Manager is successful in
reducing depreciation  or losses  arising from  either interest  rate or  credit
risks  depends in part  on the Investment  Manager's portfolio management skills
and judgment in  evaluating the factors  affecting the value  of securities.  No
assurance can be given regarding the degree of success that will be achieved.
 
RISK CONSIDERATIONS
 
Because  of  the  special  nature  of  the  Fund's  investment  in  high  income
securities, commonly  known as  junk  bonds, the  Investment Manager  must  take
account of certain special considerations in assessing the risks associated with
such  investments. Although the  growth of the high  income securities market in
the 1980s had paralleled a long  economic expansion, recently many issuers  have
been affected by adverse economic and market conditions. It should be recognized
that  an economic  downturn or increase  in interest  rates is likely  to have a
negative effect on  the high income  bond market and  on the value  of the  high
income securities held by the Fund, as well as on the ability of the securities'
issuers to repay principal and interest on their borrowings.
 
    The prices of high income securities have been found to be less sensitive to
changes  in  prevailing interest  rates than  higher-rated investments,  but are
likely to be more sensitive to adverse economic changes or individual  corporate
developments.  During  an  economic  downturn or  substantial  period  of rising
interest rates, highly leveraged issuers  may experience financial stress  which
would  adversely affect  their ability to  service their  principal and interest
payment obligations,  to  meet  their  projected business  goals  or  to  obtain
additional financing. If the issuer of a fixed-income security owned by the Fund
defaults,  the Fund may incur additional expenses to seek recovery. In addition,
periods of  economic uncertainty  and change  can be  expected to  result in  an
increased   volatility  of  market  prices  of  high  income  securities  and  a
concomitant volatility in the net asset value of a share of the Fund.  Moreover,
the
 
6
<PAGE>
market prices of certain of the Fund's portfolio securities which are structured
as  zero coupon and payment-in-kind securities  are affected to a greater extent
by interest rate changes  and thereby tend to  be more volatile than  securities
which  pay interest periodically and in  cash (see "Dividends, Distributions and
Taxes" for  a  discussion  of  the tax  ramifications  of  investments  in  such
securities).
 
    The  secondary market for high income securities may be less liquid than the
markets for higher quality securities and,  as such, may have an adverse  effect
on  the market prices of certain securities. The limited liquidity of the market
may also adversely affect the ability of the Fund's Trustees to arrive at a fair
value for certain  high income  securities at certain  times and  could make  it
difficult  for the Fund  to sell certain  securities. In addition,  new laws and
proposed new laws  may have  an adverse  effect upon  the value  of high  income
securities and a concomitant negative impact upon the net asset value of a share
of the Fund.
 
    During  the fiscal  year ended March  31, 1996, the  monthly dollar weighted
average ratings  of  the debt  obligations  held by  the  Fund, expressed  as  a
percentage of the Fund's total investments, were as follows:

</TABLE>
 
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 to
minimize such risks. These procedures include effecting repurchase  transactions
only  with large,  well-capitalized and  well-established financial institutions
and maintaining adequate collateralization.
 
WHEN-ISSUED AND DELAYED DELIVERY SECURITIES AND FORWARD COMMITMENTS.  From  time
to time, in the ordinary course of business, the Fund may purchase securities on
a  when-issued or delayed delivery basis or may purchase or sell securities on a
forward commitment basis. When  such transactions are  negotiated, the price  is
fixed  at the time of the commitment, but  delivery and payment can take place a
month or  more after  the  date of  the commitment.  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 accrues
to the purchaser during this period. An increase in the percentage of the Fund's
assets committed  to  the  purchase  of securities  on  a  when-issued,  delayed
delivery  or forward commitment basis may  increase the volatility of the Fund's
net asset value.
 
WHEN, AS AND IF ISSUED SECURITIES.  The Fund may purchase securities on a "when,
as and if issued" basis  under which the issuance  of the security depends  upon
the  occurrence of a subsequent  event, such as approval  of a merger, corporate
reorganization, leveraged buyout or debt restructuring. If the anticipated event
does not occur and  the securities are  not issued, the Fund  will have lost  an
investment  opportunity.  There is  no overall  limit on  the percentage  of the
Fund's assets which may be committed to  the purchase of securities on a  "when,
as  and if  issued" basis. An  increase in  the percentage of  the Fund's assets
committed to the purchase of securities on a "when, as and if issued" basis  may
increase the volatility of its net asset value.
 
PRIVATE  PLACEMENTS.   The Fund  may invest  up to  10% of  its total  assets in
securities which are  subject to restrictions  on resale because  they have  not
been  registered under the  Securities Act of 1933,  as amended (the "Securities
Act"), or which are otherwise  not readily marketable. (Securities eligible  for
resale  pursuant to  Rule 144A  under the Securities  Act, and  determined to be
liquid pursuant to the procedures discussed in the following paragraph, are  not
subject  to the foregoing restriction.)  These securities are generally referred
to as private placements or restricted securities. Limitations on the resale  of
such  securities  may have  an adverse  effect on  their marketability,  and may
prevent the Fund from disposing of them promptly at reasonable prices. The  Fund
may  have to bear the expense of  registering such securities for resale and the
risk of substantial delays in effecting such registration.
 
    The Securities  and Exchange  Commission  has adopted  Rule 144A  under  the
Securities  Act,  which  permits  the  Fund  to  sell  restricted  securities to
qualified institutional  buyers  without  limitation.  The  Investment  Manager,
pursuant  to  procedures  adopted by  the  Trustees  of the  Fund,  will  make a
determination as to the liquidity of  each restricted security purchased by  the
Fund.  If a restricted security is determined to be "liquid", such security will
not be included within the  category "illiquid securities", which under  current
policy may not exceed 15% of the Fund's net
 
                                                                               7
<PAGE>
assets.  However, investing  in Rule  144A Securities  could have  the effect of
increasing the level of Fund illiquidity to the extent the Fund, at a particular
point in time, may be unable  to find qualified institutional buyers  interested
in purchasing such securities.
 
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 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 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.
 
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.
 
INVESTMENT IN REAL ESTATE INVESTMENT TRUSTS.  The Fund may invest in real estate
investment trusts,  which pool  investors' funds  for investments  primarily  in
commercial  real estate properties. Investment  in real estate investment trusts
may be the most  practical available means  for the Fund to  invest in the  real
estate industry (the Fund is prohibited from investing in real estate directly).
As  a shareholder  in a real  estate investment  trust, the Fund  would bear its
ratable share  of the  real estate  investment trust's  expenses, including  its
advisory  and administration fees. At  the same time the  Fund would continue to
pay its own investment management fees and  other expenses as a result of  which
the  Fund and its stockholders  in effect will be  absorbing duplicate levels of
fees with respect to investments in real estate investment trusts.
 
RIGHTS AND WARRANTS.   The  Fund may acquire  rights and/or  warrants which  are
attached  to  other  securities in  its  portfolio,  or which  are  issued  as a
distribution by the issuer  of a security held  in its portfolio. Rights  and/or
warrants  are, in  effect, options to  purchase equity securities  at a specific
price, generally valid for a specific period of time, and have no voting rights,
pay no dividends  and have  no rights with  respect to  the corporation  issuing
them.
 
CONVERTIBLE SECURITIES.  Among the fixed-income securities in which the Fund may
invest   are  "convertible"  securities.  A  convertible  security  is  a  bond,
debenture, note, preferred stock or other security that may be converted into or
exchanged for a prescribed  amount of common  stock of the  same or a  different
issuer  within a  particular period  of time  at a  specified price  or formula.
Convertible securities rank senior to  common stocks in a corporation's  capital
structure  and, therefore, entail less risk than the corporation's common stock.
The value of a convertible security is a function of its "investment value" (its
value as if it did not have a conversion privilege), and its "conversion  value"
(the security's worth if it were to be exchanged for the underlying security, at
market  value, pursuant to its conversion privilege). Fluctuations in the prices
of an  underlying  security  will  affect  the  conversion  value  and  cause  a
concomitant fluctuation in the price of the convertible security.
 
    To the extent that a convertible security's investment value is greater than
its  conversion  value,  its  price  will  be  primarily  a  reflection  of such
investment value and its  price will be likely  to increase when interest  rates
fall and decrease when interest rates rise, as with a fixed-income security (the
credit  standing of the issuer and other factors  may also have an effect on the
convertible security's value).  If the conversion  value exceeds the  investment
value,  the price  of the  convertible security  will rise  above its investment
value and, in  addition, will sell  at some premium  over its conversion  value.
(This  premium  represents  the  price  investors are  willing  to  pay  for the
privilege of purchasing a  fixed-income security with  a possibility of  capital
appreciation  due to the conversion  privilege.) At such times  the price of the
convertible security  will tend  to fluctuate  directly with  the price  of  the
underlying equity security.
 
    Because  of the special nature of  the Fund's permitted investments in lower
rated convertible securities, the
 
8
<PAGE>
Investment Manager  must  take  account of  certain  special  considerations  in
assessing  the risks associated with such investments. The prices of lower rated
securities have  been  found to  be  less  sensitive to  changes  in  prevailing
interest  rates  than  higher  rated  investments, but  are  likely  to  be more
sensitive to  adverse economic  changes  or individual  corporate  developments.
During  an economic  downturn or  substantial period  of rising  interest rates,
highly leveraged issuers may experience  financial stress which would  adversely
affect   their  ability  to   service  their  principal   and  interest  payment
obligations, to  meet their  projected business  goals or  to obtain  additional
financing. If the issuer of a lower rated convertible security owned by the Fund
defaults,  the Fund may incur additional expenses to seek recovery. In addition,
periods of  economic uncertainty  and change  can be  expected to  result in  an
increased   volatility  of  market  prices  of  lower  rated  securities  and  a
corresponding volatility in the net asset value of a share of the Fund.
 
FOREIGN SECURITIES.   The Fund may  invest in securities  of foreign  companies.
Foreign  securities investments may be affected  by changes in currency rates or
exchange control regulations, change in governmental administration or  economic
or monetary policy (in the United States and abroad) or changed circumstances in
dealings  between nations. Costs will be incurred in connection with conversions
between various currencies held by  the Fund. Investments in foreign  securities
will also occasion risks relating to political and economic developments abroad,
including   the   possibility  of   expropriations  or   confiscatory  taxation,
limitations on the use  or transfer of  Fund assets and  any effects of  foreign
social, economic or political instability.
 
FORWARD  FOREIGN CURRENCY EXCHANGE  CONTRACTS.  The Fund  may enter into forward
foreign currency exchange  contracts ("forward  contracts") as  a hedge  against
fluctuations in future foreign exchange rates. The Fund will conduct its foreign
currency  exchange transactions either on a spot  (i.e., cash) basis at the spot
rate prevailing in  the foreign  currency exchange market,  or through  entering
into  forward  contracts  to  purchase or  sell  foreign  currencies.  A forward
contract involves an  obligation to purchase  or sell a  specific currency at  a
future date, which may be any fixed number of days from the date of the contract
agreed  upon by the parties, at a price  set at the time of the contract. Should
forward prices decline  during the  period between  the Fund's  entering into  a
forward  contract for the sale of a foreign currency and the date it enters into
an offsetting contract for the purchase  of the foreign currency, the Fund  will
realize  a gain to  the extent the price  of the currency it  has agreed to sell
exceeds the price  of the  currency it has  agreed to  purchase. Should  forward
prices  increase, the  Fund will suffer  a loss to  the extent the  price of the
currency it has  agreed to purchase  exceeds the  price of the  currency it  has
agreed to sell.
 
COMMON STOCKS.  The Fund may directly purchase common stocks on the open market.
In addition, the Fund may acquire common stocks when they are included in a unit
with fixed-income securities purchased by the Fund; when fixed-income securities
held  by the  Fund are  converted to  equity issues;  when the  Fund exercises a
warrant; and when the Fund purchases  the common stock of companies involved  in
takeovers or recapitalization, where the issuer or a stockholder has offered, or
pursuant  to a "going private" transaction is effecting, a transaction involving
the issuance of  newly issued  fixed-income securities  to the  holders of  such
common stock.
 
    The  prices  of  common stock  are  generally  more volatile  than  those of
fixed-income securities. Moreover, not all common stock pay dividends and  those
that  do generally pay lower amounts than most fixed-income securities. The Fund
will only purchase common stocks  directly when the Investment Manager  believes
that their purchase will assist the Fund in meeting its investment objectives.
 
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.
 
INVESTMENT IN REAL ESTATE INVESTMENT TRUSTS.  The Fund may invest in real estate
investment  trusts,  which pool  investors' funds  for investments  primarily in
commercial real estate properties. Investment  in real estate investment  trusts
may  be the most  practical available means for  the Fund to  invest in the real
estate industry (the Fund is prohibited from investing in real estate directly).
As a shareholder  in a real  estate investment  trust, the Fund  would bear  its
ratable  share of  the real  estate investment  trust's expenses,  including its
advisory and administration fees.  At the same time  the Fund would continue  to
pay  its own investment management fees and other expenses, as a result of which
the Fund and its shareholders in effect will
 
                                                                               9

be absorbing duplicate levels of fees with respect to investments in real estate
investment trusts.
 
OPTIONS AND FUTURES TRANSACTIONS
 
The Fund  may  purchase and  sell  (write) call  and  put options  on  portfolio
securities  which are denominated  in either U.S.  dollars or foreign currencies
and on the U.S. dollar and foreign currencies, which are or may in the future be
listed on  several U.S.  and  foreign securities  exchanges  or are  written  in
over-the-counter transactions ("OTC options"). OTC options are purchased from or
sold  (written) to  dealers or  financial institutions  which have  entered into
direct agreements with the Fund.
 
    The Fund is permitted to write covered call options on portfolio  securities
and  the U.S. dollar  and foreign currencies,  without limit, in  order to hedge
against the  decline in  the  value of  a security  or  currency in  which  such
security  is denominated, to earn  additional income and to  close out long call
option positions. The Fund may write  covered put options, under which the  Fund
incurs  an obligation  to buy the  security (or currency)  underlying the option
from the purchaser of the put at the option's exercise price at any time  during
the option period, at the purchaser's election.
 
    The  Fund  may purchase  listed  and OTC  call  and put  options  in amounts
equalling up to 5% of  its total assets. The Fund  may purchase call options  to
close out a covered call position or to protect against an increase in the price
of  a security it  anticipates purchasing or, in  the case of  call options on a
foreign currency,  to hedge  against  an adverse  exchange  rate change  of  the
currency  in  which  the  security  it  anticipates  purchasing  is  denominated
vis-a-vis the currency in which the exercise price is denominated. The Fund  may
purchase  put options on securities  which it holds in  its portfolio to protect
itself against a decline in the value  of the security and 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.
 
    The  Fund may purchase and sell futures contracts that are currently traded,
or may in  the future  be traded,  on U.S.  and foreign  commodity exchanges  on
underlying  portfolio securities, on any  currency ("currency" futures), on U.S.
and foreign  fixed-income  securities  ("interest rate"  futures)  and  on  such
indexes  of U.S. or  foreign equity or  fixed-income securities as  may exist or
come into being ("index" futures). The  Fund may purchase or sell interest  rate
futures  contracts for the  purpose of hedging some  or all of  the value of its
portfolio securities (or  anticipated portfolio securities)  against changes  in
prevailing interest rates. The Fund may purchase or sell index futures contracts
for  the  purpose  of hedging  some  or  all of  its  portfolio  (or anticipated
portfolio) securities against changes in their prices (or the currency in  which
they  are  denominated). 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  also  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.
 
    New futures  contracts, options  and other  financial products  and  various
combinations  thereof continue to be developed. The  Fund may invest in any such
futures, options or products as may be developed, to the extent consistent  with
its investment objective and applicable regulatory requirements.
 
RISKS  OF OPTIONS AND FUTURES TRANSACTIONS.  The Fund may close out its position
as writer of an option, or as a buyer or seller of a futures contract, only if a
liquid secondary market exists for options or futures contracts of that  series.
There is no assurance that such a market will exist, particularly in the case of
OTC options, as such options may generally only be closed out by entering into a
closing  purchase transaction  with the  purchasing dealer.  Also, exchanges may
limit the amount by which  the price of many futures  contracts may move on  any
day.  If the price moves  equal the daily limit on  successive days, then it may
prove impossible to  liquidate a futures  position until the  daily limit  moves
have ceased.
 
    While the futures contracts and options transactions to be engaged in by the
Fund  for  the  purpose  of  hedging the  Fund's  portfolio  securities  are not
speculative in nature, there are risks inherent in the use of such  instruments.
One  such  risk  is  that  the Investment  Manager  could  be  incorrect  in its
expectations as to  the direction or  extent of various  interest rate or  price
movements  or the time span within which  the movements take place. For example,
if the Fund sold futures contracts for the sale of securities in anticipation of
an increase  in interest  rates,  and then  interest  rates went  down  instead,
causing  bond prices  to rise,  the Fund  would lose  money on  the sale  of the
futures contract. Another risk which  will arise in employing futures  contracts
to  protect against  the price  volatility of  portfolio securities  is that the
prices of securities, currencies and  indexes subject to futures contracts  (and
thereby the futures contract prices) may correlate imperfectly with the behavior
of  the U.S.  dollar cash  prices of the  Fund's portfolio  securities and their
denominated currencies.  See  the  Statement of  Additional  Information  for  a
further discussion of risks.
 
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
 
10
<PAGE>
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 April 30, 1996. Peter M. Avelar, 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 its inception. Mr. Avelar has been  managing
portfolios  consisting of fixed-income and equity securities at InterCapital for
over five years.
 
    Although the Fund  does not engage  in substantial short-term  trading as  a
means  of achieving its  investment objective, it  may sell portfolio securities
without regard to the length of time they have been held, in accordance with the
investment policies described earlier.  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. Under normal circumstances,
it is  not anticipated  that the  portfolio trading  will result  in the  Fund's
portfolio  turnover rate  exceeding 200%  in any one  year. The  Fund will incur
underwriting discount  costs (on  underwritten securities)  and brokerage  costs
commensurate  with its portfolio turnover rate.  Short-term gains and losses may
result from  such  portfolio  transactions. See  "Dividends,  Distributions  and
Taxes" for a discussion of the tax implications of the Fund's trading policy.
 
INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------
 
The  investment restrictions listed below are  among the restrictions which have
been adopted by the Fund as  fundamental policies. Under the Investment  Company
Act  of 1940, as  amended (the "Act"),  a fundamental policy  may not be changed
without the vote of a majority of the outstanding voting securities of the Fund,
as defined  in the  Act. For  purposes  of the  following limitations:  (i)  all
percentage limitations apply immediately after a purchase or initial investment,
and  (ii)  any subsequent  change in  any  applicable percentage  resulting from
market fluctuations or  other changes in  total or net  assets does not  require
elimination of any security from the portfolio.
 
    The Fund may not:
 
        1.  As to 75% of its  total assets, invest more than  5% of the value of
    its total assets in the securities of any one issuer (other than obligations
    issued or  guaranteed  by the  United  States Government,  its  agencies  or
    instrumentalities).
 
        2.  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,  its  agencies or
    instrumentalities.
 
        3. Invest more than 5% of the value of its total assets in securities of
    issuers having  a record,  together with  predecessors, of  less than  three
    years  of  continuous operation.  This restriction  shall  not apply  to any
    obligation issued  or  guaranteed  by  the  United  States  Government,  its
    agencies or instrumentalities.
 
        4.  As to 75% of its total assets,  purchase more than 10% of the voting
    securities of any issuer.
 
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 brokers and dealers who have entered into 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. Minimum subsequent purchases of $100
or more may  be made  by sending  a check, payable  to Dean  Witter High  Income
Securities, 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,  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
 
                                                                              11
<PAGE>
determined following  receipt  of an  order  (see "Determination  of  Net  Asset
Value").
 
    Shares  of  the Fund  are sold  through  the Distributor  on a  normal three
business day settlement basis; that is, payment is due on the third business day
(settlement date) after the order is placed with the Distributor. Shares of  the
Fund  purchased through the  Distributor are entitled  to any dividends declared
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 any
dividends declared 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. 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.
 
ANALOGOUS  DEAN WITTER FUNDS.  The  Distributor and the Investment Manager serve
in the same capacities for Dean  Witter High Yield Securities Inc., an  open-end
investment  company with investment objectives and  policies similar to those of
the Fund. Unlike the Fund, however, shares of Dean Witter High Yield  Securities
Inc.  are offered  to the  public with  a sales  charge imposed  at the  time of
purchase,  rather  than  a  contingent  deferred  sales  charge  assessed   upon
redemption  within  five years  of purchase.  These two  Dean Witter  Funds have
differing fees and expenses, which will affect performance. Investors who  would
like  to receive a prospectus for Dean  Witter High Yield Securities Inc. should
call the telephone numbers listed on the front cover of this Prospectus, or  may
call their account executive for additional information.
 
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 payable monthly, at an annual rate of 0.80% 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  capital   gains
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  services
and/or the maintenance of shareholder accounts.
 
    Amounts  paid  under  the Plan  are  paid  to the  Distributor  for 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's
account executives and others who engage in or support distribution of shares or
who  service shareholder  accounts, including  overhead and  telephone expenses;
printing and distribution of  prospectuses and reports  used in connection  with
the  offering  of the  Fund's  shares to  other  than current  shareholders; and
preparation, printing  and  distribution  of sales  literature  and  advertising
materials.  In addition, the  Distributor may utilize fees  paid pursuant to the
Plan to compensate DWR and  other Selected Broker-Dealers for their  opportunity
costs  in advancing such amounts,  which compensation would be  in the form of a
carrying charge on any unreimbursed expenses.
 
    For the fiscal year  ended March 31, 1996,  the Fund accrued payments  under
the  Plan amounting to $2,640,686, which amount  is equal to 0.80% of the Fund's
average daily net  assets for the  period. 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  the  excess  distribution  expenses,
including the carrying charge described above, totalled $12,773,251 at March 31,
1996, which was equal to 2.53% 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, such excess  amount, if any, 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
dis-
 
12
<PAGE>
tribution 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) an equity  portfolio
security  listed or traded on  the New York or  American Stock Exchange or other
domestic or foreign stock exchange or quoted  by NASDAQ is valued at its  latest
sale  price on that exchange or quotation  service prior to the time when assets
are valued (if  there were  no sales  that day, the  security is  valued at  the
latest  bid  price)  (in cases  where  a security  is  traded on  more  than one
exchange, the  security is  valued on  the exchange  designated as  the  primary
market  pursuant  to procedures  adopted  by the  Trustees);  and (2)  all other
portfolio securities for  which over-the-counter market  quotations are  readily
available  are valued at  the latest bid  price. When market  quotations are not
readily available, including circumstances under  which it is determined by  the
Investment  Manager that sale and bid prices  are not reflective of a security's
market value, portfolio securities are valued at their fair value as  determined
in  good faith under procedures established by and under the general supervision
of the Board of Trustees.
 
    Short-term debt securities with remaining  maturities of sixty days or  less
at  the  time of  purchase are  valued  at amortized  cost, unless  the Trustees
determine such does  not reflect  the securities'  market value,  in which  case
these  securities  will be  valued  at their  fair  value as  determined  by the
Trustees.
 
    Certain of  the Fund's  portfolio securities  may be  valued by  an  outside
pricing service approved by the Fund's Trustees. The pricing service may utilize
a  matrix  system incorporating  security quality,  maturity  and coupon  as the
evaluation model parameters, and/or research evaluations by its staff, including
review of broker-dealer market price quotations, in determining what it believes
is the  fair  valuation of  the  portfolio  securities valued  by  such  pricing
service.
 
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  as acquired are  not subject  to the  imposition of a
contingent deferred sales  charge upon  their redemption  (see "Redemptions  and
Repurchases").
 
INVESTMENT  OF 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 for  use  by
corporations,  the self-employed,  Individual Retirement  Accounts and Custodial
Accounts under
 
                                                                              13
<PAGE>
Section 403(b)(7) of the Internal Revenue Code. Adoption of such plans should be
on advice of legal counsel or tax adviser.
 
    For further information  regarding plan administration,  custodial fees  and
other   details,  investors   should  contact   their  DWR   or  other  Selected
Broker-Dealer account executive or the Transfer Agent.
 
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  Intermediate  Term U.S.
Treasury Trust,  Dean Witter  Short-Term  Bond Fund,  Dean Witter  Limited  Term
Municipal  Trust, Dean Witter Balanced Growth  Fund, Dean Witter Balanced Income
Fund and five  Dean Witter  Funds which are  money market  funds (the  foregoing
eleven  non-CDSC funds are hereinafter collectively referred to as the "Exchange
Funds"). Exchanges may be made after the shares of the Fund acquired by purchase
(not by exchange or dividend reinvestment) have been held for thirty days. There
is no waiting period  for exchanges of shares  acquired by exchange or  dividend
reinvestment.
 
    An exchange to another CDSC fund or to any Exchange Fund that is not a money
market  fund is on the basis of the next calculated net asset value per share of
each fund after  the exchange order  is received. When  exchanging into a  money
market  fund from the Fund, shares  of the Fund are redeemed  out of the Fund at
their next calculated  net asset value  and the proceeds  of the redemption  are
used  to  purchase shares  of the  money market  fund at  their net  asset value
determined the following business day.  Subsequent exchanges between any of  the
money  market funds and any of the 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 which are exchanged for shares of another CDSC fund having a
higher CDSC schedule than that of the Fund will be subject to the CDSC  schedule
of  the other CDSC fund, even if shares are subsequently re-exchanged for shares
of the Fund prior to redemption.  Concomitantly, shares of the Fund acquired  in
exchange  for shares of another CDSC fund having a lower 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 one and examine it carefully before
investing.  Exchanges are subject to the  minimum investment requirement and any
other conditions imposed by each fund. In the
 
14
<PAGE>
case of  any  shareholder  holding  a  share  certificate  or  certificates,  no
exchanges  may be made until the share  certificate(s) have been received by the
Transfer Agent and deposited in the  shareholder's account. An exchange will  be
treated  for federal income tax purposes the  same as a repurchase of redemption
of shares, on which the shareholder may realize a capital gain or loss. However,
the ability to deduct capital losses on an exchange may be limited in situations
where there is an  exchange of shares  within ninety days  after the shares  are
purchased.  The Exchange Privilege is only available in states where an exchange
may legally be made.
 
    If DWR or another Selected Broker-Dealer is the current dealer of record and
its account  numbers  are part  of  the account  information,  shareholders  may
initiate  an exchange of shares of the Fund for shares of any of the Dean Witter
Funds (for which the Exchange Privilege is available) pursuant to this  Exchange
Privilege   by  contacting  their  account   executive  (no  Exchange  Privilege
Authorization Form is required). Other shareholders (and those shareholders  who
are  clients  of DWR  or  other Selected  Broker-Dealers  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 experience 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 certificates with
a written request for redemption, along with any additional information required
by the Transfer Agent.
 
CONTINGENT DEFERRED SALES CHARGE.   Shares of the Fund  which are held for  five
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 five years  after purchase may, however, be  subject
to  a charge upon redemption. This charge is called a "contingent deferred sales
charge" ("CDSC"), and it  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:

    A CDSC will not be imposed on:  (i) any amount which represents an  increase
in  value of  shares purchased within  the five years  preceding the redemption;
(ii) the current net asset value of shares purchased more than five 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.
 
                                                                              15
<PAGE>
    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  or Custodial  Account under Section  403(b)(7) of  the Internal Revenue
Code, provided in either case that  the redemption is requested within one  year
of the death or initial determination of disability;
 
    (2)   redemptions  in   connection  with   the  following   retirement  plan
distributions:  (A) lump-sum or  other distributions from a qualified  corporate
or  self-employed retirement plan following retirement (or in the case of a "key
employee" of  a "top  heavy" plan,  following attainment  of age  59 1/2;    (B)
distributions  from an Individual Retirement  Account or Custodial Account under
Section 403(b)(7)  of the  Internal  Revenue Code  following attainment  of  age
59 1/2); and  (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,
an  affiliate  of  the Investment  Manager,  serves as  recordkeeper  or 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
or telegraphic request of the shareholder. The repurchase price is the net asset
value  next computed (see "Purchase of Fund Shares") after such repurchase order
is received by DWR  or other Selected Broker-Dealer,  reduced by any  applicable
CDSC.
 
    The  CDSC, if any, will be the only fee imposed by the Fund, the Distributor
or DWR or  other Selected  Broker-Dealer. The offer  by DWR  and other  Selected
Broker-Dealers  to  repurchase shares  may be  suspended  without notice  by the
Distributor at any  time. In that  event, shareholders may  redeem their  shares
through the Fund's Transfer Agent as set forth above under "Redemption."
 
PAYMENT  FOR SHARES REDEEMED  OR REPURCHASED.  Payment  for shares presented for
repurchase or redemption will be made  by check within seven days after  receipt
by  the Transfer Agent of the certificate  and/or written request in good order.
Such payment may be postponed or the right of redemption suspended under unusual
circumstances. If the  shares to  be redeemed  have recently  been purchased  by
check,  payment of the redemption  proceeds may be delayed  for the minimum time
needed to verify that the check used  for investment has been honored (not  more
than  fifteen days from the time of receipt of the check by the Transfer Agent).
Shareholders  maintaining  margin   accounts  with  DWR   or  another   Selected
Broker-Dealer  are referred to their account executive regarding restrictions on
redemption of shares of the Fund pledged in the margin account.
 
REINSTATEMENT PRIVILEGE.  A shareholder who  has had his or her shares  redeemed
or  repurchased and  has not  previously exercised  this reinstatement privilege
may, within  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  their  net  asset  value  next  determined  after  a
reinstatement request, together with the  proceeds, is received by the  Transfer
Agent  and receive a pro-rata  credit for any CDSC  paid in connection with such
redemption or repurchase.
 
INVOLUNTARY REDEMPTION.  The Fund reserves the right, on sixty days' notice,  to
redeem  and at net asset value, the shares of any shareholder (other than shares
held in  an Individual  Retirement Account  or Custodial  Account under  Section
403(b)(7)  of the Internal Revenue Code) whose  shares due to redemptions by the
shareholder have a value of less than $100 or such lesser amount as may be fixed
by the Trustees  or, in the  case of  an account opened  through EasyInvest,  if
after  twelve  months  the shareholder  has  invested  less than  $1,000  in the
account. However, before the Fund redeems such shares and sends the proceeds  to
the  shareholder, it will notify the shareholder that the value of the shares is
less than the  applicable amount  and allow  him or her  sixty days  to make  an
additional  investment in an amount which will  increase the value of his or her
account to at least the applicable amount before the redemption is processed. No
CDSC will be imposed on any involuntary redemption.

DIVIDENDS, DISTRIBUTIONS AND TAXES
- --------------------------------------------------------------------------------
 
DIVIDENDS AND DISTRIBUTIONS.  The Fund intends to declare and pay monthly income
dividends and to distribute net short-term  and net long-term capital gains,  if
any,  at  least once  each  year. The  Fund  may, however,  determine  either to
distribute or to retain all or part  of any long-term capital gains in any  year
for reinvestment.
 
    All  dividends and  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 and  such
request is received by the close of business on the day prior to the record date
for  such  distributions.  (See "Shareholder  Services--Automatic  Investment of
Dividends and Distributions".)
 
TAXES.  Because the Fund intends to distribute all of its net investment  income
and  net capital gains  to shareholders and  otherwise continue to  qualify as a
regulated investment company under Subchapter M of the Internal Revenue Code, it
is not expected that the Fund will be required to pay any Federal income tax  on
such income and capital gains.
 
    With  respect to the  Fund's investments in  zero coupon and payment-in-kind
bonds, the  Fund accrues  income prior  to  any actual  cash payments  by  their
issuers.  In order to comply with Subchapter  M of the Internal Revenue Code and
be able to forego payment of Federal income tax on its income and capital gains,
the Fund must  distribute all  of its  net investment  income, including  income
accrued  from zero coupon  and payment-in-kind bonds.  As such, the  Fund may be
required to dispose of  some of its  portfolio securities under  disadvantageous
circumstances to generate the cash required for distribution.
 
    Shareholders  will  normally  have  to pay  Federal  income  taxes,  and any
applicable state and/or local income  taxes, on the dividends and  distributions
they receive from the Fund. Such dividends and distributions, to the extent they
are  derived from  net investment  income or  net short-term  capital gains, are
taxable to the shareholder as ordinary dividend income regardless of whether the
shareholder receives such  distributions in  additional shares or  in cash.  Any
dividends  declared in the last calendar quarter  of any year to shareholders of
record for that period which  are paid in the  following calendar year prior  to
February  1 will  be deemed  received by the  shareholder in  the prior calendar
year. Since the Fund's income is expected to be derived primarily from  interest
rather  than dividends,  only a  small portion,  if any,  of such  dividends and
distributions is  expected to  be eligible  for the  Federal dividends  received
deduction available to corporations.
 
    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. Capital gains may be generated by transactions
in options and futures contracts engaged in by the Fund.
 
    The  Fund may at times  make payments from sources  other than income or net
capital gains. Payments from such sources will, in effect, represent a return of
a portion of each shareholder's investment. All, or a portion, of such  payments
will not be taxable to shareholders.
 
    After the end of the calendar year, shareholders will receive a statement of
their  dividends  and capital  gains distributions  for tax  purposes, including
information as to the portion taxable as ordinary income and the portion taxable
as capital gains.
 
    To avoid being subject  to a 31% Federal  backup withholding tax on  taxable
dividends,  capital  gains distributions  and  the proceeds  of  redemptions and
repurchases, shareholders' taxpayer identification numbers must be furnished and
certified as to their accuracy.
 
    Shareholders should consult their tax advisers regarding specific  questions
as to state or local taxes and as to the applicability of the foregoing to their
current federal tax situation.
 
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 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
 
                                                                              17
<PAGE>
expenses  incurred by the  Fund and all sales  charges incurred by shareholders,
for the  stated  period. 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, and year-by-year  or
other  types of total return figures. The  Fund may also advertise the growth of
hypothetical investments of $10,000, $50,000 and $100,000 in shares of the Fund.
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  from time  to time  may  also advertise  its performance  relative  to
certain  performance rankings and indexes compiled by independent organizations,
such as mutual fund performance rankings of Lipper Analytical Services, Inc.
 
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  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.

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

        CONDITIONAL  RATING:  Municipal bonds for which the security 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  unseasoned in  operation
    experience,  (c) rentals which  begin when facilities  are completed, or
    (d)  payments  to   which  some  other   limiting  condition   attaches.
    Parenthetical  rating denotes probable credit stature upon completion of
    construction or elimination of basis of condition.
 
        RATING REFINEMENTS:  Moody's may apply numerical modifiers, 1, 2 and
    3 in  each  generic rating  classification  from  Aa through  B  in  its
    corporate  and municipal  bond rating  system. The  modifier 1 indicates
    that the  security  ranks  in  the higher  end  of  its  generic  rating
    category; the modifier 2 indicates a mid-range ranking; and a modifier 3
    indicates  that the issue ranks  in the lower end  of its generic rating
    category.
 
                            COMMERCIAL PAPER RATINGS
 
        Moody's Commercial  Paper ratings  are opinions  of the  ability  to
    repay  punctually promissory obligations not having an original maturity
    in  excess  of  nine  months.   Moody's  employs  the  following   three
    designations,  all  judged  to  be  investment  grade,  to  indicate the
    relative repayment capacity of rated issuers: Prime-1, Prime-2, Prime-3.
 
       Issuers rated  Prime-1  have a  superior  capacity for  repayment  of
    short-term  promissory obligations. Issuers rated  Prime-2 have a strong
    capacity for repayment of short-term promissory obligations; and Issuers
    rated Prime-3 have  an acceptable capacity  for repayment of  short-term
    promissory  obligations. Issuers rated Not Prime  do not fall within any
    of the Prime rating categories.
 
    STANDARD & POOR'S CORPORATION ("STANDARD & POOR'S")
 
                                    BOND RATINGS
 
       A Standard  & Poor's  bond  rating is  a  current assessment  of  the
    creditworthiness  of an obligor  with respect to  a specific obligation.
    This assessment may take into consideration obligors such as guarantors,
    insurers, or lessees.
 
       The ratings are based on current information furnished by the  issuer
    or  obtained  by  Standard  & Poor's  from  other  sources  it considers
    reliable. The ratings are  based, in varying  degrees, on the  following
    considerations:  (1) likelihood  of default-capacity  and willingness of
    the obligor  as to  the  timely payment  of  interest and  repayment  of
    principal  in accordance with the terms of the obligation; (2) nature of
    and provisions of the  obligation; and (3)  protection afforded by,  and
    relative  position  of,  the  obligation  in  the  event  of bankruptcy,
    reorganization or other  arrangement under  the laws  of bankruptcy  and
    other laws affecting creditors' rights.
 
       Standard  & Poor's does  not perform an audit  in connection with any
    rating and may,  on occasion, rely  on unaudited financial  information.
    The  ratings  may be  changed,  suspended or  withdrawn  as a  result of
    changes in,  or  unavailability  of,  such  information,  or  for  other
    reasons.
 
<TABLE>
<S>        <C>
AAA        Debt  rated AAA has the highest rating assigned  by Standard & Poor's. Capacity to pay
           interest and repay principal is extremely strong.
AA         Debt rated AA  has a  very strong  capacity to pay  interest and  repay principal  and
           differs from the highest-rated issues only in small degree.
A          Debt  rated A has a strong capacity to  pay interest and repay principal although they
           are somewhat more susceptible to the  adverse effects of changes in circumstances  and
           economic conditions than debt in higher-rated categories.
BBB        Debt  rated BBB is regarded  as having an adequate capacity  to pay interest and repay
           principal. Whereas  it  normally  exhibits  adequate  protection  parameters,  adverse
           economic  conditions or changing circumstances  are more likely to  lead to a weakened
           capacity to pay interest and repay principal  for debt in this category than for  debt
           in higher-rated categories.
           Bonds rated AAA, AA, A and BBB are considered investment grade bonds.
BB         Debt rated BB has less near-term vulnerability to default than other speculative grade
           debt.  However, it faces major ongoing  uncertainties or exposure to adverse business,
           financial or  economic conditions  which could  lead to  inadequate capacity  to  meet
           timely interest and principal payment.
B          Debt  rated B has a greater vulnerability to default but presently has the capacity to
           meet interest  payments  and  principal repayments.  Adverse  business,  financial  or
           economic  conditions would likely  impair capacity or willingness  to pay interest and
           repay principal.
</TABLE>

<PAGE>
<TABLE>
<S>        <C>
CCC        Debt rated CCC has a current  identifiable vulnerability to default, and is  dependent
           upon  favorable business, financial and economic conditions to meet timely payments of
           interest and repayments of principal. In  the event of adverse business, financial  or
           economic  conditions, it is not likely to have  the capacity to pay interest and repay
           principal.
CC         The rating  CC is  typically applied  to debt  subordinated to  senior debt  which  is
           assigned an actual or implied CCC rating.
C          The  rating  C is  typically  applied to  debt subordinated  to  senior debt  which is
           assigned an actual or implied CCC- debt rating.
CI         The rating CI is reserved for income bonds on which no interest is being paid.
D          Debt rated "D" is in  payment default. The "D" rating  category is used when  interest
           payments  or principal payments  are not made on  the date due  even if the applicable
           grace period has  not expired, unless  S&P believes  that such payments  will be  made
           during  such grace  period. The  "D" rating  also will  be used  upon the  filing of a
           bankruptcy petition if debt service payments are jeopardized.
NR         Indicates that no rating has been requested, that there is insufficient information on
           which to base a rating or  that Standard & Poor's does  not rate a particular type  of
           obligation as a matter of policy.
           Bonds  rated BB,  B, CCC, CC  and C  are regarded as  having predominantly speculative
           characteristics with  respect to  capacity to  pay interest  and repay  principal.  BB
           indicates  the least degree  of speculation and  C the highest  degree of speculation.
           While such debt will  likely have some quality  and protective characteristics,  these
           are outweighed by large uncertainties or major risk exposures to adverse conditions.
           Plus (+) or minus (-): The ratings from AA to CCC may be modified by the addition of a
           plus or minus sign to show relative standing within the major ratings categories.
           In  the case of municipal bonds, 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 RATINGS
 
        Standard and Poor's commercial paper rating is a current  assessment
    of  the likelihood of timely payment of debt having an original maturity
    of no  more  than  365  days.  The commercial  paper  rating  is  not  a
    recommendation  to purchase  or sell a  security. The  ratings are based
    upon current information furnished by the issuer or obtained by S&P from
    other sources  it  considers  reliable.  The  ratings  may  be  changed,
    suspended,  or withdrawn as a result  of changes in or unavailability of
    such information. Ratings are graded into group categories, ranging from
    "A" for the highest quality obligations  to "D" for the lowest.  Ratings
    are  applicable  to both  taxable and  tax-exempt commercial  paper. The
    categories are as follows:
 
       Issues assigned  A  ratings  are  regarded  as  having  the  greatest
    capacity for timely payment. Issues in this category are further refined
    with  the designation  1, 2  and 3  to indicate  the relative  degree of
    safety.
 
<TABLE>
<S>        <C>
    A-1    indicates that the degree of safety regarding timely payment is very strong.
    A-2    indicates capacity for timely  payment on issues with  this designation is  strong.
           However,  the  relative degree  of  safety is  not  as overwhelming  as  for issues
           designated "A-1".
    A-3    indicates a satisfactory  capacity for  timely payment.  Obligations carrying  this
           designation  are,  however,  somewhat more  vulnerable  to the  adverse  effects of
           changes in circumstances than obligations carrying the higher designations.
