RISK               The  net asset value of  the Fund's shares will  fluctuate with changes in the
CONSIDERATIONS     market value  of the  Fund's portfolio  securities. The  value of  the  Fund's
                   convertible  and  fixed-income  portfolio  securities  generally  increase  or
                   decrease due to  changes in prevailing  interest rates. Generally,  a rise  in
                   interest  rates will result in  a decrease in value,  while a drop in interest
                   rates will  result  in  an  increase  in value.  The  high  yield,  high  risk
                   fixed-income  securities in which  the Fund may invest  are subject to greater
                   risk of  loss  of income  and  principal  than higher  rated,  lower  yielding
                   fixed-income  securities. The prices of high  yield, high risk 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.  The  Fund  is   a
                   non-diversified  investment  company  and,  as such,  is  not  subject  to the
                   diversification requirements  of  the  Investment  Company  Act  of  1940,  as
                   amended. As a result, a relatively high percentage of the Fund's assets may be
                   invested in a limited number of issuers. However, the Fund intends to continue
                   to qualify as a regulated investment company under the federal income tax laws
                   and,  as such, is subject to  the diversification requirements of the Internal
                   Revenue Code. The Fund may invest up to 25% of its total assets in  non-dollar
                   denominated  foreign securities, which may entail  special risks (see page 7).
                   The Fund also may engage in options and futures transactions and may  purchase
                   securities  on a  when-issued, delayed  delivery or  "when, as  and if issued"
                   basis, which involve certain additional risks (see page 10).

THE FUND AND ITS MANAGEMENT
- --------------------------------------------------------------------------------
 
    TCW/DW Income and Growth Fund  (the "Fund") is an open-end,  non-diversified
management investment company. The Fund is a trust of the type commonly known as
a   "Massachusetts  business  trust"  and  was   organized  under  the  laws  of
Massachusetts on November 23, 1992.
 
    Dean Witter  Services Company  Inc. (the  "Manager"), whose  address is  Two
World Trade Center, New York, New York 10048, is the Fund's Manager. The Manager
is  a wholly-owned subsidiary of Dean Witter InterCapital Inc. ("InterCapital").
InterCapital is  a  wholly-owned  subsidiary  of Dean  Witter,  Discover  &  Co.
("DWDC"),  a balanced financial services organization providing a broad range of
nationally marketed credit and investment products.
 
    On February 5, 1997, DWDC and Morgan Stanley Group Inc. announced that  they
had  entered into an Agreement and Plan  of Merger, with the combined company to
be named Morgan  Stanley, Dean  Witter, Discover &  Co. The  business of  Morgan
Stanley  Group Inc. and  its affiliated companies  is providing a  wide range of
financial services  for sovereign  governments, corporations,  institutions  and
individuals  throughout the world. DWDC is the direct parent of InterCapital and
Dean  Witter  Distributors  Inc.,  the  Fund's  distributor.  It  is   currently
anticipated   that  the   transaction  will   close  in   mid-1997.  Thereafter,
InterCapital and Dean Witter  Distributors Inc. will  be direct subsidiaries  of
Morgan Stanley, Dean Witter, Discover & Co.
 
    The  Manager acts as manager to thirteen other TCW/DW Funds. The Manager and
InterCapital act  in various  investment  management, advisory,  management  and
administrative  capacities to  a total  of 101  investment companies,  thirty of
which are  listed  on the  New  York Stock  Exchange,  with combined  assets  of
approximately  $89.8 billion as of February  28, 1997. InterCapital also manages
and advises  portfolios of  pension plans,  other institutions  and  individuals
which aggregated approximately $3.2 billion at such date.
 
    The  Fund has retained the Manager to manage its business affairs, supervise
its overall day-to-day operations (other  than providing investment advice)  and
provide all administrative services.
 
    TCW  Funds  Management, Inc.  (the "Adviser"),  whose  address is  865 South
Figueroa Street,  Suite  1800, Los  Angeles,  California 90017,  is  the  Fund's
investment  adviser.  The  Adviser  was  organized  in  1987  as  a wholly-owned
subsidiary of The TCW Group,  Inc. ("TCW"), whose subsidiaries, including  Trust
Company  of the  West and  TCW Asset  Management Company,  provide a  variety of
trust, investment management  and investment advisory  services. Robert A.  Day,
who  is Chairman of the Board of Directors of TCW, may be deemed to be a control
person of the Adviser by  virtue of the aggregate ownership  by Mr. Day and  his
family  of more than 25% of the outstanding  voting stock of The TCW Group, Inc.
The Adviser  serves as  investment adviser  to thirteen  other TCW/DW  Funds  in
addition  to the Fund. As  of February 28, 1997,  the Adviser and its affiliated
companies had  over $50  billion under  management or  committed to  management,
primarily from institutional investors.
 
    The Fund has retained the Adviser to invest the Fund's assets.
 
    The  Fund's Trustees review the various services provided by the Manager and
the Adviser to ensure that the  Fund's general investment policies and  programs
are  being  properly  carried out  and  that administrative  services  are being
provided to the Fund in a satisfactory manner.
 
    As full compensation for the services  and facilities furnished to the  Fund
and  for expenses of the Fund assumed by  the Manager, the Fund pays the Manager
monthly compensation calculated daily  by applying the annual  rate of 0.45%  to
the  Fund's net assets up  to $500 million, scaled down  to 0.42% on assets over
$500 million. As  compensation for  its investment advisory  services, the  Fund
pays  the Adviser  monthly compensation calculated  daily by  applying an annual
rate of 0.30% to the Fund's net assets up to $500 million, scaled down to  0.28%
on  assets over $500  million. For the  fiscal year ended  January 31, 1997, the
Fund   accrued   total   compensation   to   the   Manager   and   the   Adviser
 
                                       6

amounting  to 0.45%  and 0.30%,  respectively, of  the Fund's  average daily net
assets. During that period, the Fund's  total expenses amounted to 2.02% of  the
Fund's average daily net assets.
 
INVESTMENT OBJECTIVE AND POLICIES
- --------------------------------------------------------------------------------
 
    The  investment objective of  the Fund is  to generate high  total return by
providing a  high  level  of  current  income  and  the  potential  for  capital
appreciation.  This  objective is  fundamental and  may  not be  changed without
shareholder approval. There is no assurance that the objective will be achieved.
 
    The Fund  seeks  to  achieve  its  investment  objective  by  investing,  in
descending  order of preference under current market conditions, at least 65% of
its total assets in any or all  of the following types of securities: (1)  bonds
or preferred stock convertible into common stock ("convertible securities"); (2)
other  fixed-income securities, including bonds, notes, debentures and preferred
stocks; (3) common stocks; and (4) U.S. Government securities (securities issued
or guaranteed by the United States or its agencies or instrumentalities).
 
    The Fund will invest at  least 50% of its total  assets in a combination  of
equity  securities and  fixed-income securities  with equity  components such as
convertible securities and  warrants. In addition,  all fixed-income  securities
without  an equity  component in  which the  Fund invests  will have  a weighted
average life or a maturity date of ten years or less.
 
    The Fund  may  invest  in  convertible  securities  and  other  fixed-income
securities  rated below investment grade.  Securities below investment grade are
the equivalent of  high yield, high  risk bonds. Investment  grade is  generally
considered  to  be debt  securities rated  BBB  or higher  by Standard  & Poor's
Corporation ("S&P")  or  Baa  or  higher  by  Moody's  Investors  Service,  Inc.
("Moody's").  (Convertible and other fixed-income securities rated BBB by S&P or
Baa by Moody's, which generally are  regarded as having an adequate capacity  to
pay  interest and  repay principal, have  speculative characteristics.) However,
the Fund will not invest in  convertible and other fixed-income securities  that
are  rated lower than B by S&P or Moody's  or, if not rated, determined to be of
comparable quality by  the Adviser.  The Fund  will not  invest in  fixed-income
securities  that  are  in  default  in  payment  of  principal  or  interest.  A
description of fixed-income securities ratings  is contained in the Appendix  to
this Prospectus.
 
PORTFOLIO CHARACTERISTICS
 
    CONVERTIBLE  SECURITIES.  A convertible security is a bond, debenture, note,
preferred stock or other security that may be converted into or exchanged for  a
prescribed  amount of common  stock of the  same or a  different issuer within a
particular period of time at a specified price or based on a specified  formula.
Convertible  securities rank senior to common  stocks in a corporation's capital
structure and, therefore, entail less risk than the corporation's common  stock.
The value of a convertible security is a function of its "investment value" (its
value  as if it did not have a conversion privilege), and its "conversion value"
(the security's worth if it were to be exchanged for the underlying security, at
market value, pursuant to its conversion privilege).
 
    To the extent that a convertible security's investment value is greater than
its conversion  value,  its  price  will  be  primarily  a  reflection  of  such
investment  value and its price  will be likely to  increase when interest rates
fall and decrease when interest rates rise, as with a fixed-income security (the
credit standing of the issuer and other  factors may also have an effect on  the
convertible  security's value). If  the conversion value  exceeds the investment
value, the price  of the  convertible security  will rise  above its  investment
value  and, in  addition, may  sell at some  premium over  its conversion value.
(This premium  represents  the  price  investors are  willing  to  pay  for  the
privilege  of purchasing a  fixed-income security with  a possibility of capital
appreciation due to the  conversion privilege.) At such  times the price of  the
convertible  security  will tend  to fluctuate  directly with  the price  of the
underlying equity security.
 
    FOREIGN SECURITIES.  The Fund may invest in securities of foreign companies.
The Fund  may invest  in  Eurodollar convertible  securities, which  are  fixed-
 
                                       7
<PAGE>
income  securities of a U.S.  or foreign issuer that  are issued in U.S. dollars
outside the United States  and are convertible into  or exchangeable for  equity
securities  of  the  same  or  a different  issuer.  Interest  and  dividends on
Eurodollar securities are payable in U.S. dollars outside of the United  States.
The Fund may invest without limitation in Eurodollar convertible securities that
are  convertible  into or  exchangeable for  U.S.  or foreign  equity securities
listed, or represented by American Depository  Receipts listed, on a U.S.  stock
exchange.  The  Fund's investments  in  other Eurodollar  convertible securities
which are exchangeable for unlisted foreign equity securities are subject to the
Fund's overall policy limiting its investment  in illiquid securities to 15%  or
less of its net assets.
 
    The  Fund will not invest more than 25% of the value of its total assets, at
the time of purchase, in  non-dollar denominated foreign securities (other  than
securities  of Canadian issuers registered under  the Securities Exchange Act of
1934 or American  Depository Receipts,  on which there  is no  such limit).  The
Fund's  investments in  unlisted foreign  securities are  subject to  the Fund's
overall policy limiting its investment in illiquid securities to 15% or less  of
its  net assets.  Foreign securities investments  may be affected  by changes in
currency  rates  or  exchange  control  regulations,  changes  in   governmental
administration  or economic or monetary policy (in the United States and abroad)
or changed circumstances in dealings between  nations. Costs may be incurred  in
connection  with conversions  between various currencies  held by  the Fund. The
Fund currently does not intend  to invest more than 25%  of its total assets  in
the  securities of issuers in  any one country outside  the United States. For a
discussion of the risks of foreign securities, see "Risk Considerations," below.
 
RISK CONSIDERATIONS
 
    The net asset value of the Fund's shares will fluctuate with changes in  the
market  value of the Fund's portfolio securities. The market value of the Fund's
portfolio securities will  increase or decrease  due to a  variety of  economic,
market  and political factors  affecting the creditworthiness  of the underlying
issuers, as well as changes in prevailing  interest rates, none of which can  be
predicted.  A decline in  prevailing interest rates  will generally increase the
value of fixed-income securities, while an increase in rates usually reduces the
value of those securities. The Fund's yield also will vary based on the yield of
the Fund's portfolio securities.
 
    HIGH YIELD, HIGH RISK  SECURITIES.  Because  of the ability  of the Fund  to
invest in certain high yield, high risk convertible and fixed-income securities,
the  Adviser must take  into account the  special nature of  such securities and
certain special  considerations  in assessing  the  risks associated  with  such
investments.  Although the  growth of  the high  yield 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  yield  bond market  and  on the  value  of the  high  yield
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 yield 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 yield securities and a concomitant
volatility in the net asset value of a share of the Fund.
 
    The  secondary market for high yield 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  yield securities  at certain  times and  could make  it
difficult for the Fund to sell certain securities.
 
                                       8
<PAGE>
In addition, new laws and potential new laws may have an adverse effect upon the
value  of high yield securities  and a concomitant negative  impact upon the net
asset value of a share of the Fund.
 
    For a discussion  of the  risks of the  Fund's status  as a  non-diversified
investment  company, see "Other Investment Policies," below. For a discussion of
warrants and  stock  rights, see  "Warrants  and  Stock Rights,"  below.  For  a
discussion  of the risks  of options and futures  transactions, see "Options and
Futures Transactions," below.
 
    During the fiscal year ended January  31, 1997, 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>
 
    FOREIGN SECURITIES    Foreign  securities investments  may  be  affected  by
changes   in  currency  rates  or   exchange  control  regulations,  changes  in
governmental administration or economic or monetary policy (in the United States
and abroad) or changed circumstances  in dealings between nations.  Fluctuations
in  the relative rates  of exchange between the  currencies of different nations
will affect the value of the Fund's investments denominated in foreign currency.
Changes in foreign  currency exchange  rates relative  to the  U.S. dollar  will
affect  the U.S. dollar value of the  Fund's assets denominated in that currency
and thereby impact upon the Fund's total return on such assets.
 
    Foreign currency  exchange rates  are  determined by  forces of  supply  and
demand  on the foreign exchange markets. These forces are themselves affected by
the  international  balance  of  payments  and  other  economic  and   financial
conditions,  government intervention,  speculation and  other factors. Moreover,
foreign currency exchange rates may be affected by the regulatory control of the
exchanges on which the currencies trade.
 
    Investments in  foreign  securities will  also  occasion risks  relating  to
political  and  economic  developments  abroad,  including  the  possibility  of
expropriations or confiscatory taxation, limitations  on the use or transfer  of
Fund   assets  and  any  effects  of   foreign  social,  economic  or  political
instability. Foreign companies are not subject to the regulatory requirements of
U.S. companies and, as  such, there may be  less publicly available  information
about  such companies.  Moreover, foreign companies  are not  subject to uniform
accounting,  auditing  and  financial   reporting  standards  and   requirements
comparable to those applicable to U.S. companies.
 
    Securities  of foreign issuers may be less liquid than comparable securities
of U.S.  issuers  and,  as such,  their  price  changes may  be  more  volatile.
Furthermore,  foreign exchanges and broker-dealers are generally subject to less
government  and   exchange  scrutiny   and   regulation  than   their   American
counterparts.  Brokerage commissions,  dealer concessions  and other transaction
costs may be higher on foreign markets than in the U.S. In addition, differences
in clearance and settlement procedures on foreign markets may occasion delays in
settlements of  the  Fund's  trades  effected in  such  markets.  As  such,  the
inability  to dispose  of portfolio  securities due  to settlement  delays could
result in  losses to  the  Fund due  to subsequent  declines  in value  of  such
securities and the inability of the Fund to make intended security purchases due
to settlement problems could result in a failure of the Fund to make potentially
advantageous   investments.  To   the  extent  the   Fund  purchases  Eurodollar
certificates of deposit  issued by  foreign branches of  domestic United  States
banks,  consideration will be  given to their  domestic marketability, the lower
reserve requirements  normally mandated  for  overseas banking  operations,  the
possible   impact  of  interruptions  in  the  flow  of  international  currency
transactions and future international political and economic developments  which
might adversely affect the payment of principal or interest.

<PAGE>
    The  risks of other investment techniques which  may be utilized by the Fund
are described  under  "Other  Investment  Policies"  and  "Options  and  Futures
Transactions" below.
 
WARRANTS AND STOCK RIGHTS
 
    The  Fund may invest  up to 5% of  the value of its  net assets in warrants,
including not more  than 2% in  warrants not listed  on either the  New York  or
American  Stock Exchange. The Fund may also invest  up to 5% of the value of its
net assets  in stock  rights. Warrants  are, in  effect, an  option to  purchase
equity  securities at a specific price, generally valid for a specific period of
time, and  have no  voting rights,  pay no  dividends and  have no  rights  with
respect  to the  corporations issuing  them. The  Fund may  acquire warrants and
stock rights attached  to other  securities without reference  to the  foregoing
limitations.
 
OTHER INVESTMENT POLICIES
 
   
    While the Fund invests primarily in the types of securities described above,
under  ordinary circumstances  it may invest  up to  35% of its  total assets in
money market instruments,  which are  short-term (maturities of  up to  thirteen
months) fixed-income securities issued by private and governmental institutions.
Money  market instruments in which the Fund  may invest are securities issued or
guaranteed by the U.S. Government or its agencies; obligations of banks  subject
to  regulation by the U.S.  Government and having total  assets of $1 billion or
more; Eurodollar  certificates  of deposit;  obligations  of savings  banks  and
savings  and loan associations having total assets  of $1 billion or more; fully
insured certificates  of deposit;  and  commercial paper  rated within  the  two
highest grades by Moody's or S&P or, if not rated, issued by a company having an
outstanding debt issue rated AAA by S&P or Aaa by Moody's.
    
 
    There  may be periods  during which, in  the opinion of  the Adviser, market
conditions warrant reduction of some or  all of the Fund's securities  holdings.
During such periods, the Fund may adopt a temporary "defensive" posture in which
greater  than 35% of its total assets is invested in money market instruments or
cash.
 
    The Fund is  classified as  a non-diversified investment  company under  the
Investment  Company Act of  1940, as amended  (the "Act"), and,  as such, is not
limited by the Act  in the proportion of  its assets that it  may invest in  the
obligations  of  a  single issuer.  However,  the  Fund intends  to  conduct its
operations so as to qualify as a "regulated investment company" under Subchapter
M of the  Internal Revenue Code.  See "Dividends, Distributions  and Taxes."  In
order  to qualify, among other requirements, the Fund will limit its investments
so that at the close of each quarter of the taxable year, (i) not more than  25%
of  the  market  value  of the  Fund's  total  assets will  be  invested  in the
securities of a single issuer, and (ii) with respect to 50% of the market  value
of  its total assets  not more than 5%  will be invested in  the securities of a
single issuer and the Fund will not own more than 10% of the outstanding  voting
securities  of a single issuer. To the  extent that a relatively high percentage
of the Fund's assets may be invested  in the obligations of a limited number  of
issuers,  the Fund's portfolio securities may  be more susceptible to any single
economic, political or regulatory occurrence than the portfolio securities of  a
diversified  investment company. The limitations described in this paragraph are
not fundamental policies  and may be  revised to the  extent applicable  Federal
income tax requirements are revised.
 
    REPURCHASE AGREEMENTS.  The Fund may enter into repurchase agreements, which
may  be viewed  as a type  of secured lending  by the Fund,  and which typically
involve the acquisition by the Fund of debt securities from a selling  financial
institution  such as a bank, savings  and loan association or broker-dealer. The
agreement provides that the Fund will sell back to the institution, and that the
institution will repurchase, the underlying security at a specified price and at
a fixed time in the  future, usually not more than  seven days from the date  of
purchase.  While repurchase agreements involve certain risks not associated with
direct investments  in  debt  securities,  including the  risks  of  default  or
bankruptcy  of the  selling financial  institution, the  Fund follows procedures
designed to minimize those risks. These procedures include effecting  repurchase
transactions  only with  large, well-capitalized  and well-established financial
institutions and maintaining adequate collateralization.
 
                                       10
<PAGE>
    WHEN-ISSUED AND DELAYED DELIVERY SECURITIES  AND FORWARD COMMITMENTS.   From
time  to  time,  in the  ordinary  course  of business,  the  Fund  may purchase
securities on a when-issued  or delayed delivery basis  or may purchase or  sell
securities on a forward commitment basis. When such transactions are negotiated,
the  price is fixed at the time of  the commitment, but delivery and payment can
take place a month or more after the date of the commitment. There is no overall
limit on the  percentage of  the Fund's  assets which  may be  committed to  the
purchase  of securities on a when-issued, delayed delivery or forward commitment
basis. An  increase in  the percentage  of the  Fund's assets  committed to  the
purchase  of securities on a when-issued, delayed delivery or forward commitment
basis may increase the volatility of the Fund's net asset value.
 
    WHEN, AS AND IF ISSUED  SECURITIES.  The Fund  may purchase securities on  a
"when,  as and if issued" basis under which the issuance of the security depends
upon the  occurrence  of a  subsequent  event, such  as  approval of  a  merger,
corporate  reorganization,  leveraged  buyout  or  debt  restructuring.  If  the
anticipated event does  not occur and  the securities are  not issued, the  Fund
will  have lost  an investment  opportunity. There  is no  overall limit  on the
percentage of  the Fund's  assets which  may  be committed  to the  purchase  of
securities on a "when, as and if issued" basis. An increase in the percentage of
the  Fund's assets committed to the purchase of securities on a "when, as and if
issued" basis may increase the volatility of  its net asset value. The Fund  may
also  sell securities  on a  "when, as  and if  issued" basis  provided that the
issuance of  the  security  will  result  automatically  from  the  exchange  or
conversion of a security owned by the Fund at the time of the sale.
 
    PRIVATE  PLACEMENTS.  The  Fund may invest up  to 5% of  its total assets in
securities which are  subject to restrictions  on resale because  they have  not
been  registered under the  Securities Act of 1933,  as amended (the "Securities
Act"), or which are otherwise  not readily marketable. (Securities eligible  for
resale  pursuant to  Rule 144A  under the Securities  Act, and  determined to be
liquid pursuant to the procedures discussed in the following paragraph, are  not
subject  to the foregoing restriction.)  These securities are generally referred
to as private placements or restricted securities. Limitations on the resale  of
such  securities  may have  an adverse  effect on  their marketability,  and may
prevent the Fund from disposing of them promptly at reasonable prices. The  Fund
may  have to bear the expense of  registering such securities for resale and the
risk of substantial delays in effecting such registration.
 
The  Securities  and  Exchange  Commission  has  adopted  Rule  144A  under  the
Securities  Act,  which  permits  the  Fund  to  sell  restricted  securities to
qualified institutional  buyers without  limitation.  The Adviser,  pursuant  to
procedures  adopted by the Trustees of the Fund, will make a determination as to
the liquidity of each restricted security purchased by the Fund. If a restricted
security is determined to be "liquid," such security will not be included within
the category "illiquid securities,"  which under current  policy may not  exceed
15%  of the Fund's net assets. However,  investing in Rule 144A securities could
have the effect of increasing  the level of Fund  illiquidity to the extent  the
Fund,  at  a  particular  period  in  time,  may  be  unable  to  find qualified
institutional buyers in purchasing such securities.
 
    INVESTMENT IN OTHER INVESTMENT VEHICLES.   Under the Investment Company  Act
of 1940, as amended, the Fund generally may invest up to 10% of its total assets
in  the aggregate in  shares of other investment  companies and up  to 5% of its
total assets in any one investment company. The Fund may not own more than 3% of
the voting stock of any investment company. In addition, the Fund may invest  in
real  estate  investment trusts,  which  pool investors'  funds  for investments
primarily in commercial real estate  properties. Investment in other  investment
companies  may  be  the sole  or  most practical  means  by which  the  Fund may
participate in  certain  securities  markets,  and  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 an investment company or real estate
investment trust,  the  Fund would  bear  its  ratable share  of  that  entity'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 be
absorbing
 
                                       11
<PAGE>
duplicate levels  of  fees  with  respect to  investments  in  other  investment
companies and in real estate investment trusts.
 
    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.
 
OPTIONS AND FUTURES TRANSACTIONS
 
    The Fund may  purchase and sell  (write) call and  put options on  portfolio
securities  and on the U.S. dollar  which are or may in  the future be listed on
securities exchanges  or  are  written in  over-the-counter  transactions  ("OTC
Options"). Listed options are issued or guaranteed by the exchange on which they
trade or by a clearing corporation such as the Options Clearing Corporation. 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, without limit, in order to aid it in achieving its investment objective.
The Fund may also write covered put options; however, the aggregate value of the
obligations underlying the puts determined as  of the date the options are  sold
will not exceed 50% of the Fund's net assets.
 
    The  Fund may purchase listed and OTC call and put options on securities and
stock indexes 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. The Fund may
purchase put  options on  securities which  it holds  in its  portfolio only  to
protect itself against a decline in the value of the security. The Fund may also
purchase  put options to close out written  put positions in a manner similar to
call option closing  purchase transactions.  There are  no other  limits on  the
Fund's ability to purchase call and put options.
 
    The  Fund may also purchase  and sell interest rate  and stock index futures
contracts ("futures contracts") that are  traded on U.S. commodity exchanges  on
such  underlying securities  as U.S. Treasury  bonds, notes, and  bills and GNMA
Certificates ("interest rate" futures) and such indexes as the S&P 500 Index and
the New York  Stock Exchange  Composite Index  ("stock index"  futures) and  the
Moody's Investment-Grade Corporation Bond Index ("bond index" futures). The Fund
will  purchase or  sell interest rate  futures contracts and  bond index futures
contracts for the purpose of hedging its fixed-income portfolio (or  anticipated
portfolio)  against changes in prevailing interest rates and to alter the Fund's
asset allocation  in fixed-income  securities. The  Fund will  purchase or  sell
stock  index futures contracts  for the purpose of  hedging its equity portfolio
(or anticipated portfolio) against changes in their prices.
 
    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.
 
                                       12
<PAGE>
    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 Adviser  could be incorrect in its expectations as  to
the  direction or extent of various interest rate or price movements or the time
span within  which the  movements take  place.  For example,  if the  Fund  sold
futures  contracts for the sale of securities  in anticipation of an increase in
interest rates, and then interest rates  went down instead, causing bond  prices
to rise, the Fund would lose money on the sale. Another risk which 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 dollar cash prices of the Fund's portfolio
securities and their  denominated currencies.  See the  Statement of  Additional
Information for a further discussion of such risks.
 
PORTFOLIO MANAGEMENT
 
    The  Fund's portfolio  is actively  managed by  its Adviser  with a  view to
achieving the Fund's  investment objective. Robert  M. Hanisee, Mark  Attanasio,
Kevin  A. Hunter and Melissa Weiler, Managing  Directors of the Adviser, are the
primary portfolio  managers of  the Fund.  Messrs. Hanisee  and Hunter  and  Ms.
Weiler  have been primary portfolio  managers of the Fund  since April, 1995 and
Mr. Attanasio  has been  a portfolio  manager  of the  Fund since  March,  1996.
Messrs.  Hanisee and Hunter have been  portfolio managers with affiliates of The
TCW Group, Inc.  since 1990  and 1989, respectively.  Mr. Attanasio  has been  a
portfolio  manager with the  TCW Group Inc. and  affiliates thereof since April,
1995. Prior  thereto  he was  Co-Chief  Executive Officer  and  Chief  Portfolio
Strategist of Crescent Corporation (April, 1991-April 1995). Ms. Weiler has been
a  portfolio manager with affiliates  of The TCW Group,  Inc. since April, 1995,
and prior thereto was a Vice President and Portfolio Manager of Crescent Capital
Corporation, an Investment  Adviser, with  which she had  been affiliated  since
February  1992.  Prior thereto,  she was  a Senior  Investment Analyst  at First
Capital Holdings Corporation.
 
    In determining which  securities to  purchase for the  Fund or  hold in  the
Fund's  portfolio, the  Adviser will rely  on information  from various sources,
including research, analysis  and appraisals of  brokers and dealers,  including
Dean Witter Reynolds Inc. ("DWR"), a broker-dealer affiliate of the Manager, and
others  regarding  economic  developments  and  interest  rate  trends,  and the
Adviser's own analysis of factors it deems relevant.
 
    Orders for transactions in portfolio  securities and commodities are  placed
for  the Fund with a number of brokers  and dealers, including DWR. 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 100% in any one year. The Fund will
incur brokerage costs commensurate with its portfolio turnover rate.
 
    Except  as  specifically  noted,  all  investment  policies  and   practices
discussed  above are not fundamental  policies of the Fund  and, as such, may be
changed without shareholder approval.

INVESTMENT RESTRICTIONS
- --------------------------------------------------------------------------------
 
    The investment restrictions  listed below are  among the restrictions  which
have  been  adopted  by the  Fund  as  fundamental policies.  Under  the  Act, a
fundamental policy may  not be changed  without the  vote of a  majority of  the
outstanding  voting securities of the Fund, as  defined in the Act. For purposes
of the following limitations: (i)  all percentage limitations apply  immediately
after  a purchase or initial  investment, and (ii) any  subsequent change in any
applicable percentage resulting  from market  fluctuations or  other changes  in
total  or  net assets  does not  require  elimination of  any security  from the
portfolio.
 
    The Fund may not:
 
      1. Invest 25% or more  of the value of its  total assets in securities  of
    issuers  in any one industry. This restriction does not apply to obligations
    issued or  guaranteed  by the  United  States Government,  its  agencies  or
    instrumentalities.
 
      2.  Invest more than 5% of the value  of its total assets in securities of
    issuers having  a record,  together with  predecessors, of  less than  three
    years   of  continuous  operation.  This   restriction  does  not  apply  to
    obligations issued  or  guaranteed  by the  United  States  Government,  its
    agencies or instrumentalities.
 
    In addition, as a non-fundamental policy, the Fund may not, 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 Manager, shares of
the Fund are distributed by the Distributor and offered by DWR and others (which
may include  TCW Brokerage  Services,  an affiliate  of  the Adviser)  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  and subsequent purchases of $100 or
more may be made by sending a  check, payable to TCW/DW Income and Growth  Fund,
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  another
Selected  Broker-Dealer. The minimum initial purchase in the case of investments
through EasyInvest-SM-, an automatic purchase plan (see "Shareholder Services"),
is $100, provided  that the  schedule of  automatic investments  will result  in
investments  totalling at  least $1,000 within  the first twelve  months. In the
case of investments  pursuant to Systematic  Payroll Deduction Plans  (including
Individual   Retirement  Plans),  the  Fund,   in  its  discretion,  may  accept
investments without  regard to  any  minimum amounts  which would  otherwise  be
required  if the  Fund has  reason to  believe that  additional investments will
increase the investment  in all accounts  under such Plans  to at least  $1,000.
Certificates for shares purchased will not be issued unless a request is made by
the shareholder in writing to the Transfer Agent.
 
    Shares  of  the Fund  are sold  through  the Distributor  on a  normal three
business day settlement basis; that is, payment is due on the third business day
(settlement date) after the order is placed with the Distributor. Since DWR  and
other  Selected Broker-Dealers forward investors' funds on settlement date, they
will benefit  from the  temporary use  of the  funds if  payment is  made  prior
thereto.  As noted above, orders placed directly with the Transfer Agent must be
accompanied by payment. Investors will  be entitled to receive income  dividends
and  capital gains  distributions if  their order  is received  by the  close of
business  on  the  day  prior  to  the  record  date  for  such  dividends   and
distributions.
 
                                       14
<PAGE>
    The  offering price will  be the net  asset value per  share next determined
following receipt of an  order (see "Determination of  Net Asset Value").  Sales
personnel  of a  Selected Broker-Dealer are  compensated for shares  of the Fund
sold by them by  the Distributor or  any of its  affiliates and/or the  Selected
Broker-Dealer.  In addition, some sales  personnel of the Selected Broker-Dealer
will receive various types of non-cash compensation as special sales incentives,
including trips, educational and/or business seminars and merchandise. The  Fund
and the Distributor reserve the right to reject any purchase orders.
 
PLAN OF DISTRIBUTION
 
    The  Fund has  entered into  a Plan of  Distribution pursuant  to Rule 12b-1
under the Act with  the Distributor whereby the  expenses of certain  activities
and  services, including  personal services  to shareholders  and maintenance of
shareholder accounts, in connection with  the distribution of the Fund's  shares
are  reimbursed. The principal activities and  services which may be provided by
DWR, its affiliates or any other Selected Broker-Dealer under the Plan  include:
(1)  compensation  to,  and  expenses of,  DWR  account  executives  and others,
including overhead and telephone expenses;  (2) sales incentives and bonuses  to
sales  representatives and to  marketing personnel in  connection with promoting
sales of the Fund's shares; (3)  expenses incurred in connection with  promoting
sales of the Fund's shares; (4) preparing and distributing sales literature; and
(5)  providing  advertising and  promotional  activities, including  direct mail
solicitation  and  television,  radio,  newspaper,  magazine  and  other   media
advertisements.  Reimbursements  for  these  services will  be  made  in monthly
payments by the Fund, which will in no event exceed an amount equal to a payment
at the annual rate of 0.75% of the Fund's average daily net assets. A portion of
the amount payable  pursuant to  the Plan,  which may  not exceed  0.25% of  the
Fund's  average daily net assets,  is characterized as a  service fee within the
meaning of  NASD guidelines.  The service  fee is  a payment  made for  personal
service  and/or  the  maintenance  of  shareholder  accounts.  Expenses incurred
pursuant to the Plan in any fiscal year in excess of 0.75% of the Fund's average
daily net assets will not be reimbursed by the Fund through payments accrued  in
any  subsequent  fiscal  year.  The Fund  accrued  $425,303  to  the Distributor
pursuant to the  Plan for the  fiscal year ended  January 31, 1997.  This is  an
accrual at the annual rate of 0.74% of the Fund's average daily net assets.
 
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
stock  exchange is valued at its latest sale price on that exchange prior to the
time when assets are valued;  if there were no sales  that day, the security  is
valued  at the latest  bid price (in  cases where securities  are traded on more
than one exchange, the securities are  valued on the exchange designated as  the
primary  market pursuant  to procedures  adopted by  the Trustees);  and (2) all
other portfolio  securities for  which  over-the-counter market  quotations  are
readily available are valued at the latest available bid price prior to the time
of  valuation.  When  market  quotations are  not  readily  available, including
circumstances under  which it  is determined  by the  Adviser that  sale or  bid
prices are not reflective of a security's market value, portfolio securities are
valued  at  their  fair  value  as determined  in  good  faith  under procedures
established by and  under the general  supervision of the  Fund's Trustees.  For
valuation  purposes, quotations  of foreign portfolio  securities are translated
into U.S. dollar equivalents at the  prevailing market rates prior to the  close
of  the New  York Stock  Exchange. Dividends  receivable are  accrued as  of the
ex-dividend date  or as  of the  time  that the  relevant ex-dividend  date  and
amounts become known.
 
                                       15
<PAGE>
    Short-term  debt securities with remaining maturities  of 60 days or less at
the time of purchase are valued at amortized cost, unless the Trustees determine
such does  not  reflect  the  securities' market  value,  in  which  case  these
securities will be valued at their fair value as determined by the Trustees.
 
    Certain  of  the Fund's  portfolio securities  may be  valued by  an outside
pricing service approved by the Fund's Trustees. The pricing service may utilize
a matrix  system incorporating  security  quality, maturity  and coupon  as  the
evaluation  model  parameters, and/or  research  and evaluations  by  its staff,
including review of broker-dealer market  price quotations, in determining  what
it  believes is the  fair valuation of  the portfolio securities  valued by such
 
pricing service.
 
SHAREHOLDER SERVICES
- --------------------------------------------------------------------------------
 
    AUTOMATIC INVESTMENT OF  DIVIDENDS AND DISTRIBUTIONS.  All income  dividends
and  capital gains distributions  are automatically paid  in full and fractional
shares of the Fund (or, if specified by the shareholder, any other TCW/DW Fund),
unless the shareholder  requests that  they be paid  in cash.  Each purchase  of
shares of the Fund is made upon the condition that the Transfer Agent is thereby
automatically  appointed as agent  of the investor to  receive all dividends and
capital gains distributions on shares owned by the investor. Such dividends  and
distributions  will be paid, at the net asset  value per share, in shares of the
Fund (or in cash if the shareholder so requests) as of the close of business  on
the  record date.  At any time  an investor  may request the  Transfer Agent, in
writing, to have subsequent dividends and/or capital gains distributions paid to
him or her in cash  rather than shares. In order  to provide sufficient time  to
process  the change, such  request should be  received by the  Transfer Agent at
least  five  business  days  prior  to  the  record  date  of  the  dividend  or
distribution.  In the case  of recently purchased  shares for which registration
instructions have not been  received on the record  date, cash payments will  be
made  to DWR or another  Selected Broker-Dealer, which will  be forwarded to the
shareholder, upon the receipt of proper instructions.
 
    INVESTMENT OF DIVIDENDS OR DISTRIBUTIONS RECEIVED IN CASH.  Any  shareholder
who   receives  a  cash  payment  representing   a  dividend  or  capital  gains
distribution may invest such dividend or distribution at the net asset value per
share next determined  after receipt  by the  Transfer Agent,  by returning  the
check  or the proceeds  to the Transfer  Agent within 30  days after the payment
date.
 
    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 "Repurchases  and Redemptions --
Involuntary Redemption").
 
    SYSTEMATIC WITHDRAWAL PLAN.  A  systematic withdrawal plan (the  "Withdrawal
Plan")  is available  for shareholders  who own or  purchase shares  of the Fund
having a minimum value of $10,000 based  upon the then current net asset  value.
The  Withdrawal Plan provides  for monthly or  quarterly (March, June, September
and December) checks in any  dollar amount, not less than  $25, or in any  whole
percentage  of the  account balance, on  an annualized  basis. Only shareholders
having accounts  in  which  no  share certificates  have  been  issued  will  be
permitted to enroll in the Withdrawal Plan.
 
    Shareholders  should  contact  their  DWR  or  other  Selected Broker-Dealer
account executive or the Transfer Agent for further information about any of the
above services.
 
    TAX SHELTERED RETIREMENT PLANS.  Retirement  plans are available for use  by
corporations,  the self-employed,  Individual Retirement  Accounts and Custodial
Accounts under Section 403(b)(7) of the Internal
 
                                       16
<PAGE>
Revenue Code. Adoption of such plans should be on advice of legal counsel or tax
adviser.
 
    For further information  regarding plan administration,  custodial fees  and
other  details, investors should contact their account executive or the Transfer
Agent.
 
EXCHANGE PRIVILEGE
 
    An "Exchange  Privilege," that  is, the  privilege of  exchanging shares  of
certain  Funds for  shares of  the Fund, exists  whereby shares  of TCW/DW Funds
which are open-end investment companies sold with a contingent deferred (at time
of redemption) sales charge  ("CDSC Funds") may be  exchanged for shares of  the
Fund,  for  shares  of TCW/DW  North  American Government  Income  Trust, TCW/DW
Balanced Fund, and for shares of five money market funds for which  InterCapital
serves  as investment manager:  Dean Witter Liquid Asset  Fund Inc., Dean Witter
U.S. Government Money  Market Trust,  Dean Witter Tax-Free  Daily Income  Trust,
Dean  Witter California  Tax-Free Daily  Income Trust  and Dean  Witter New York
Municipal  Money  Market  Trust  (the  foregoing  eight  investment   companies,
including  the  Fund,  are  hereinafter collectively  referred  to  as "Exchange
Funds").
 
    An exchange from a CDSC Fund to an 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 a  CDSC Fund,  shares of  the CDSC  Fund are  redeemed at  their next
calculated net asset value and exchanged for shares of the money market fund  at
their  net  asset value  determined  the following  business  day. Additionally,
shares of any Exchange Fund  received in an exchange for  shares of a CDSC  Fund
(regardless  of  the type  of  fund originally  purchased)  may be  redeemed and
exchanged for  shares  of  an Exchange  Fund  or  a CDSC  Fund.  Any  applicable
contingent  deferred sales  charge ("CDSC") will  have to be  paid upon ultimate
redemption of shares originally purchased from a CDSC Fund. 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. However, in the case of shares exchanged into an Exchange Fund,  upon
a  redemption of shares which results in a  CDSC being imposed, a credit (not to
exceed the amount of the CDSC) will be given in an amount equal to the  Exchange
Fund  12b-1  distribution  fees  which are  attributable  to  those  shares (see
"Purchase of Fund  Shares --  Plan of Distribution"  in this  Prospectus or  the
respective  other Exchange  Fund prospectus for  a description  of Exchange Fund
12b-1 distribution fees). Exchanges involving CDSC  Funds may be made after  the
shares  of  the CDSC  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.
 
    Purchases  and  exchanges should  be made  for  investment purposes  only. A
pattern of frequent exchanges  may be deemed  by the Manager  to be abusive  and
contrary  to the  best interests  of the Fund's  other shareholders  and, at the
Manager's discretion, may be limited by the Fund's refusal to accept  additional
purchases  and/or exchanges from  the investor. Although the  Fund does not have
any specific definition of what constitutes a pattern of frequent exchanges, and
will consider all relevant factors in determining whether a particular situation
is abusive  and  contrary to  the  best interests  of  the Fund  and  its  other
shareholders,  investors should be aware that the Fund, each of the other TCW/DW
Funds and  each of  the money  market funds  may in  their discretion  limit  or
otherwise  restrict the number of times this Exchange Privilege may be exercised
by any investor. Any such restriction will be made by the Fund on a  prospective
basis  only, upon notice  to the shareholder  not later than  ten days following
such shareholder's most  recent exchange.  Also, the Exchange  Privilege may  be
terminated or revised at any time by the Fund and/or any of such TCW/DW Funds or
money  market funds for which shares of  the Fund have been exchanged, upon such
notice as  may  be  required by  applicable  regulatory  agencies.  Shareholders
maintaining  margin  accounts with  DWR  or another  Selected  Broker-Dealer are
referred to their account executive regarding
restric-
 
                                       17
<PAGE>
tions on exchange of shares pledged in the margin account.
 
    The current prospectus for each  fund describes its investment  objective(s)
and  policies, and  shareholders should obtain  a copy and  examine it carefully
before investing. Exchanges  are subject to  the minimum investment  requirement
and  any other conditions imposed by each  fund. An exchange will be treated for
federal income tax purposes the same as a repurchase or redemption of shares, on
which the shareholder may realize a  capital gain or loss. However, the  ability
to deduct capital losses on an exchange may be limited in situations where there
is  an exchange of shares within ninety days after the shares are purchased. The
Exchange Privilege is only available in states where an exchange may legally  be
made.
 
    If DWR or another Selected Broker-Dealer is the current dealer of record and
its  account  numbers  are part  of  the account  information,  shareholders may
initiate an exchange of shares  of the Fund for shares  of any of the funds  for
which the Exchange Privilege is available pursuant to this Exchange Privilege by
contacting  their  DWR or  other  Selected Broker-Dealer  account  executive (no
Exchange Privilege  Authorization Form  is  required). Other  shareholders  (and
those  shareholders who are clients of  DWR or 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. The  procedures include requiring
various forms of personal identification  such as name, mailing address,  social
security  or other tax  identification number and DWR  or other Selected Broker-
Dealer account number (if any). Telephone instructions will also be recorded. If
such procedures are not employed, the Fund  may be liable for any losses due  to
unauthorized or fraudulent transactions.
 
    Telephone exchange instructions will be accepted if received by the Transfer
Agent  between 9:00 a.m. and 4:00  p.m., New York time, on  any day the New York
Stock Exchange is  open. Any  shareholder wishing to  make an  exchange who  has
previously  filed an Exchange Privilege Authorization  Form and who is unable to
reach the Fund  by telephone should  contact his  or her DWR  or other  Selected
Broker-Dealer  account  executive, if  appropriate, or  make a  written exchange
request. Shareholders are  advised that  during periods of  drastic economic  or
market  changes, it  is possible that  the telephone exchange  procedures may be
difficult to implement, although  this has not  been the case  in the past  with
other funds managed by the Manager.
 
    For  further  information  regarding  the  Exchange  Privilege, shareholders
should contact their DWR  or other Selected  Broker-Dealer account executive  or
the Transfer Agent.
 
REPURCHASES AND REDEMPTIONS
- --------------------------------------------------------------------------------
 
    REPURCHASES.    DWR  and  other Selected  Broker-Dealers  are  authorized to
repurchase shares represented by a share  certificate which is delivered to  any
of  their  offices.  Shares held  in  a  shareholder's account  without  a share
certificate may also  be repurchased by  DWR and other  Selected Broker  Dealers
upon  the telephonic request of the shareholder. The repurchase price is the net
asset value next determined  (see "Purchase of Fund  Shares -- Determination  of
Net  Asset Value") after such  repurchase order is received  by DWR or the other
Selected Broker-Dealer. The offers by  DWR and other Selected Broker-Dealers  to
repurchase  shares from shareholders  may be suspended  by them at  any time. In
that event, shareholders  may redeem  their shares through  the Fund's  Transfer
Agent as set forth below under "Redemptions."
 
    REDEMPTIONS.  Shares of the Fund can be redeemed for cash at any time at net
asset  value per share  next determined. If  shares are held  in a shareholder's
 
                                       18
<PAGE>
account at the Transfer Agent without a share certificate, a written request for
redemption must be sent  to the Fund's  Transfer Agent at  P.O. Box 983,  Jersey
City,  NJ 07303. The share certificate, or  an accompanying stock power, and the
request for  redemption,  must be  signed  by the  shareholder  or  shareholders
exactly  as the shares  are registered. Each request  for redemption, whether or
not accompanied by  a share  certificate, must be  sent to  the Fund's  Transfer
Agent,  which will redeem the shares at their net asset value next determined as
described under "Purchase of  Fund Shares -- Determination  of Net Asset  Value"
after  it receives  the request,  and certificate,  if any,  in good  order. Any
redemption request received  after such  determination will be  redeemed at  the
next  determined net  asset value.  The term "good  order" means  that the share
certificate, if any, and request for redemption are properly signed, accompanied
by any  documentation  required  by  the  Transfer  Agent,  and  bear  signature
guarantees  when required by  the Fund or  the Transfer Agent.  If redemption is
requested by a corporation, partnership, trust or fiduciary, the Transfer  Agent
may  require that written evidence of authority acceptable to the Transfer Agent
be submitted before such request is accepted. With regard to shares of the  Fund
acquired  pursuant to the Exchange Privilege, any applicable contingent deferred
sales charge will be imposed upon  the redemption of such shares (see  "Purchase
of Fund Shares -- Exchange Privilege").
 
    Whether  certificates are held  by the shareholder  or shares are  held in a
shareholder's account, if the proceeds are to  be paid to any person other  than
the record owner, or if the proceeds are to be paid to a corporation (other than
DWR  or  another Selected  Broker-Dealer for  the  account of  the shareholder),
partnership, trust or fiduciary, or sent to the shareholder at an address  other
than  the  registered  address, signatures  must  be guaranteed  by  an eligible
guarantor acceptable  to the  Transfer Agent  (shareholders should  contact  the
Transfer  Agent for  a determination as  to whether a  particular institution is
such an eligible guarantor). A  stock power may be  obtained from any dealer  or
commercial  bank. The Fund may change  the signature guarantee requirements from
time to time upon  notice to shareholders,  which may be by  means of a  revised
prospectus.
 
    PAYMENT  FOR SHARES REPURCHASED  OR REDEEMED.   Payment for shares presented
for repurchase  or redemption  will be  made by  check within  seven days  after
receipt  by the Transfer Agent of the certificate and/or written request in good
order. Such payment may be postponed or the right of redemption suspended  under
unusual circumstances. If the shares to be redeemed have recently been purchased
by check, payment of the redemption proceeds may be delayed for the minimum time
needed  to verify that the check used  for investment has been honored (not more
than fifteen days from the time of receipt of the check by the Transfer  Agent).
Shareholders   maintaining  margin   accounts  with  DWR   or  another  Selected
Broker-Dealer are referred to their account executive regarding restrictions  on
redemption of shares of the Fund pledged in the margin account.
 
    REINSTATEMENT  PRIVILEGE.   A  shareholder  who has  had  his or  her shares
redeemed or  repurchased and  has not  previously exercised  this  reinstatement
privilege  may, within 30 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  net asset value  next determined  after a  reinstatement
request, together with the proceeds, is received by the Transfer Agent.
 
    INVOLUNTARY REDEMPTION.  The Fund reserves the right, on 60 days' notice, to
redeem,  at their  net asset  value, the shares  of any  shareholder (other than
shares held  in an  individual  Retirement Account  or Custodial  Account  under
Section  403(b)(7) of the Internal Revenue Code) whose shares due to redemptions
by the shareholder have a value of less  than $100 or such lesser amount as  may
be  fixed  by  the  Trustees or,  in  the  case of  an  account  offered through
EasyInvest, if after twelve months the shareholder has invested less than $1,000
in the  account. However,  before the  Fund redeems  such shares  and sends  the
proceeds  to the shareholder, it  will notify the shareholder  that the value of
the shares is less than the applicable amount and allow the shareholder 60  days
to  make an additional investment in an  amount which will increase the value of
the account  to  at  least  the  applicable  amount  before  the  redemption  is
processed.

DIVIDENDS, DISTRIBUTIONS AND TAXES
- --------------------------------------------------------------------------------
 
    DIVIDENDS  AND DISTRIBUTIONS.   The Fund intends  to pay quarterly dividends
and to distribute  substantially all of  the Fund's net  investment income.  The
Fund  intends to distribute  net short-term and net  long-term capital gains, if
any, at  least  once each  year.  The Fund  may,  however, determine  either  to
distribute  or to retain all  or part of any net  long-term capital gains in any
year for reinvestment.
 
    All dividends and any capital gains distributions will be paid in additional
Fund shares  and automatically  credited to  the shareholder's  account  without
issuance  of a share certificate unless the shareholder requests in writing that
all dividends and/or distributions be paid in cash. (See "Shareholders  Services
- -- Automatic Investment of Dividends and Distributions.")
 
    TAXES.   Because the  Fund intends to  distribute all of  its net investment
income and capital gains to shareholders and otherwise continue to qualify as  a
regulated investment company under Subchapter M of the Internal Revenue Code, it
is  not expected that the  Fund will be required to  pay any federal income tax.
Shareholders who are required to pay taxes on their income will normally have to
pay federal  income taxes,  and any  state income  taxes, on  the dividends  and
distributions  they receive from the Fund.  Such dividends and distributions, to
the extent  that they  are  derived from  net  investment income  or  short-term
capital  gains, are taxable to the  shareholder as ordinary income regardless of
whether the shareholder receives such payments in additional shares or in cash.
 
    Distributions of  net  long-term  capital  gains, if  any,  are  taxable  to
shareholders as long-term capital gains regardless of how long a shareholder has
held the Fund's shares and regardless of whether the distribution is received in
additional  shares or in cash. Capital  gains distributions are not eligible for
the corporate dividends received deduction.
 
    The Fund may at times  make payments from sources  other than income or  net
capital  gains. Payments from such  sources, in effect, represent  a return of a
portion of each shareholder's  investment. All, or a  portion, of such  payments
will not be taxable to shareholders.
 
    After  the  end  of  the  calendar  year,  shareholders  will  be  sent full
information on their dividends and capital gains distributions for tax purposes.
To avoid  being subject  to a  31%  federal backup  withholding tax  on  taxable
dividends,  capital  gains distributions  and  the proceeds  of  redemptions and
repurchases, shareholders' taxpayer identification numbers must be furnished and
certified as to their accuracy.
 
    Shareholders should consult their  tax advisers as  to the applicability  of
the foregoing to their current situation.
 
PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
 
    From  time to time the Fund may  quote its "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  net
investment  income of the Fund  over a 30-day period  by an average value (using
the average number  of shares entitled  to receive dividends  and the net  asset
value  per share at  the end of  the period), all  in accordance with applicable
regulatory requirements.  Such amount  is  compounded for  six months  and  then
annualized for a twelve-month period to derive the yield of the Fund.
 
    From  time to time the  Fund may quote its  "total return" in advertisements
and sales  literature. The  total return  of  the Fund  is based  on  historical
earnings and is not intended to indicate future performance. The "average annual
total  return" of the Fund refers to  a figure reflecting the average annualized
percentage increase (or decrease) in the  value of an initial investment in  the
Fund of $1,000 over periods of one, five and ten years, as well as over the life
of the Fund, if less than
 
                                       20
<PAGE>
any  of the foregoing. Average annual total return reflects all income earned by
the Fund, any appreciation or depreciation of the Fund's assets and all expenses
incurred by the Fund, which would be incurred by redeeming shareholders, for the
stated periods. It also assumes reinvestment of all dividends and  distributions
paid by the Fund.
 
    In  addition to the foregoing, the Fund  may advertise its total return over
different periods of time  by means of aggregate,  average, 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.
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.  Under
certain circumstances the Trustees may be removed by action of the Trustees. The
shareholders also have the right under certain circumstances to remove Trustees.
 
    Under Massachusetts law, shareholders of a business trust may, under certain
limited  circumstances, be held personally liable as partners for obligations of
the Fund. However, the  Declaration of Trust contains  an express disclaimer  of
shareholder  liability for acts  or obligations of the  Fund, requires that Fund
obligations include  such  disclaimer,  and  provides  for  indemnification  and
reimbursement  of expenses out  of the Fund's property  for any shareholder held
personally liable  for  the  obligations  of  the Fund.  Thus,  the  risk  of  a
shareholder  incurring  financial loss  on account  of shareholder  liability is
limited to circumstances in which  the Fund itself would  be unable to meet  its
obligations.  Given the above limitations on shareholder personal liability, and
the nature of the Fund's assets and operations, in the opinion of  Massachusetts
counsel to the Fund, the risk to shareholders of personal liability is remote.
 
    CODE  OF ETHICS.  The Adviser is subject to a Code of Ethics with respect to
investment transactions in which the  Adviser's officers, directors and  certain
other  persons  have a  beneficial  interest to  avoid  any actual  or potential
conflict or  abuse  of their  fiduciary  position. The  Code  of Ethics,  as  it
pertains  to  the TCW/DW  Funds,  contains several  restrictions  and procedures
designed to  eliminate conflicts  of interest  including: (a)  pre-clearance  of
personal  investment  transactions  to  ensure  that  personal  transactions  by
employees are not being conducted at the same time as the Adviser's clients; (b)
quarterly reporting  of  personal  securities transactions;  (c)  a  prohibition
against  personally acquiring securities in an initial public offering, entering
into uncovered  short sales  and  writing uncovered  options;  (d) a  seven  day
"black-out  period" prior to  or subsequent to a  TCW/DW Fund transaction during
which portfolio  managers are  prohibited from  making certain  transactions  in
securities  which  are  being  purchased  or  sold  by  a  TCW/DW  Fund;  (e)  a
prohibition, with respect to certain investment personnel, from profiting in the
purchase and sale, or sale and purchase, of the same (or equivalent)  securities
within  60 calendar days;  and (f) a prohibition  against acquiring any security
which is subject to firm wide or, if applicable, a department restriction of the
Adviser. The Code  of Ethics provides  that exemptive relief  may be given  from
certain  of its  requirements, upon  application. The  Adviser's Code  of Ethics
complies with  regulatory requirements  and, insofar  as it  relates to  persons
associated with registered investment companies, the 1994 Report of the Advisory
Group on Personal Investing of the Investment Company Institute.

RATINGS OF CORPORATE DEBT INSTRUMENTS
MOODY'S INVESTORS SERVICE INC. ("MOODY'S")
 
                         FIXED-INCOME SECURITY RATINGS
 
<TABLE>
<S>        <C>
Aaa        Fixed-income  securities 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         Fixed-income  securities which  are rated  Aa are  judged to  be of  high quality  by all
           standards. Together with the  Aaa group they  comprise what are  generally known as  high
           grade fixed-income securities. They are rated lower than the best fixed-income securities
           because  margins of protection may not be as large as in Aaa securities or fluctuation of
           protective elements may be of  greater amplitude or there  may be other elements  present
           which make the long-term risks appear somewhat larger than in Aaa securities.
A          Fixed-income  securities which are  rated A possess  many favorable investment attributes
           and are to be considered  as upper medium grade  obligations. Factors giving security  to
           principal and interest are considered adequate, but elements may be present which suggest
           a susceptibility to impairment sometime in the future.
Baa        Fixed-income  securities which are rated Baa  are considered as medium grade obligations;
           i.e., they  are  neither highly  protected  nor  poorly secured.  Interest  payments  and
           principal security appear adequate for the present but certain protective elements may be
           lacking  or may  be characteristically  unreliable over  any great  length of  time. Such
           fixed-income securities  lack outstanding  investment characteristics  and in  fact  have
           speculative characteristics as well.
           Fixed-income securities rated Aaa, Aa, A and Baa are considered investment grade.
Ba         Fixed-income securities 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  in the future.  Uncertainty of position  characterizes bonds in this
           class.
B          Fixed-income securities which are rated B generally lack characteristics of the desirable
           investment. 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        Fixed-income securities 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         Fixed-income securities 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          Fixed-income  securities which  are rated  C are the  lowest rated  class of fixed-income
           securities, and issues so  rated can be  regarded as having  extremely poor prospects  of
           ever attaining any real investment standing.
</TABLE>
 
    RATING  REFINEMENTS:  Moody's may apply numerical  modifiers, 1, 2, and 3 in
each  generic  rating  classification  from  Aa  through  B  in  its   municipal
fixed-income  security rating system. The modifier 1 indicates that the security
ranks in the higher end of its generic rating category; the modifier 2 indicates
a mid-range ranking;  and a modifier  3 indicates  that the issue  ranks in  the
lower end of its generic rating category.

                            COMMERCIAL PAPER RATINGS
 
    Moody's  Commercial  Paper  ratings are  opinions  of the  ability  to repay
punctually promissory obligations not having  an original maturity in excess  of
nine  months. The ratings apply to Municipal Commercial Paper as well as taxable
Commercial Paper. Moody's employs the  following three designations, all  judged
to  be investment  grade, to indicate  the relative repayment  capacity of rated
issuers: Prime-1, Prime-2, Prime-3.
 
    Issuers rated Prime-1 have a  superior capacity for repayment of  short-term
promissory  obligations.  Issuers  rated  Prime-2  have  a  strong  capacity for
repayment of short-term promissory obligations;  and Issuers rated Prime-3  have
an  acceptable  capacity  for repayment  of  short-term  promissory obligations.
Issuers rated Not Prime do not fall within any of the Prime rating categories.
 
STANDARD & POOR'S CORPORATION ("STANDARD & POOR'S")
 
                         FIXED-INCOME SECURITY RATINGS
 
    A Standard & Poor's fixed-income security rating is a current assessment  of
the  creditworthiness of an obligor with  respect to a specific obligation. This
assessment may take into consideration obligors such as guarantors, insurers, or
lessees.
 
    The ratings are  based on  current information  furnished by  the issuer  or
obtained  by Standard  & Poor's  from other  sources it  considers reliable. The
ratings are  based, in  varying degrees,  on the  following considerations:  (1)
likelihood  of default-capacity and willingness of  the obligor as to the timely
payment of interest and repayment of  principal in accordance with the terms  of
the  obligation;  (2)  nature  of  and provisions  of  the  obligation;  and (3)
protection afforded by, and relative position of, the obligation in the event of
bankruptcy, reorganization or other arrangement under the laws of bankruptcy and
other laws affecting creditors' rights.
 
    Standard & Poor's does  not perform an audit  in connection with any  rating
and  may, on occasion, rely on  unaudited financial information. The ratings may
be changed, suspended or withdrawn as a result of changes in, or  unavailability
of, such information, or for other reasons.
 
<TABLE>
<S>        <C>
AAA        Fixed-income  securities  rated "AAA"  have the  highest rating  assigned by  Standard &
           Poor's. Capacity to pay interest and repay principal is extremely strong.
AA         Fixed-income securities rated "AA" have a very strong capacity to pay interest and repay
           principal and differs from the highest-rated issues only in small degree.
A          Fixed-income securities  rated "A"  have a  strong capacity  to pay  interest and  repay
           principal  although they are somewhat more susceptible to the adverse effects of changes
           in circumstances and  economic conditions than  fixed-income securities in  higher-rated
           categories.
BBB        Fixed-income  securities rated "BBB" are regarded as  having an adequate capacity to pay
           interest  and  repay  principal.  Whereas  it  normally  exhibits  adequate   protection
           parameters,  adverse economic  conditions or changing  circumstances are  more likely to
           lead to  a  weakened capacity  to  pay interest  and  repay principal  for  fixed-income
           securities in this category than for fixed-income securities in higher-rated categories.
           Fixed-income securities rated AAA, AA, A and BBB are considered investment grade.
BB         Fixed-income  securities rated  "BB" have less  near-term vulnerability  to default than
           other speculative  grade  fixed-income  securities.  However,  it  faces  major  ongoing
           uncertainties  or exposure to  adverse business, financial  or economic conditions which
           could lead to inadequate capacity or willingness to pay interest and repay principal.
B          Fixed-income securities rated "B" have 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>
 
                                       23
<PAGE>
<TABLE>
<S>        <C>
CCC        Fixed-income  securities  rated  "CCC"  have  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 fixed-income securities subordinated to  senior
           debt which is assigned an actual or implied "CCC" rating.
C          The  rating "C" is  typically applied to fixed-income  securities subordinated to senior
           debt which is assigned an actual or implied "CCC-" rating.
CI         The rating "CI" is reserved  for fixed-income securities on  which no interest is  being
           paid.
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.
           Fixed-income  securities 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 fixed-income securities 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 rating from "AA" to "CCC" may be modified by the addition  of
           a plus or minus sign to show relative standing with the major ratings categories.
</TABLE>
 
                            COMMERCIAL PAPER RATINGS
 
    Standard  and Poor's commercial paper rating  is a current assessment of the
likelihood of timely payment of debt having an original maturity of no more than
365 days. The  commercial paper rating  is not a  recommendation to purchase  or
sell a security. The ratings are based upon current information furnished by the
issuer  or obtained by 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.
